31,000,000 SHARES

Fluence Energy, Inc.

CLASS A COMMON STOCK

This is an initial public offering of shares of Class A common stock of Fluence Energy, Inc. We are selling 31,000,000 shares of Class A common stock.

Prior to this offering, there has been no public market for the Class A common stock. It is currently estimated that the initial public offering price per share of Class A common stock will be between $21.00 and $24.00. We have applied to list our Class A common stock on the Nasdaq Global Market under the symbol “FLNC.”

We will have three classes of common stock after this offering: Class A common stock, Class B-1 common stock and Class B-2 common stock. Each share of our Class A common stock entitles its holder to one vote per share, each share of our Class B-1 common stock entitles its holder to five votes per share and each share of our Class B-2 common stock entitles its holder to one vote per share on all matters presented to our stockholders generally. Immediately following the consummation of this offering, all of the outstanding shares of our Class B-1 common stock will be held by the Founders (as defined below), which will represent in the aggregate approximately 92.2% of the voting power of our outstanding common stock after this offering (or approximately 91.5% if the underwriters exercise in full their option to purchase additional shares).

This offering is being conducted through what is commonly referred to as an “Up-C” structure, which is often used by partnerships and limited liability companies undertaking an initial public offering. The Up-C approach provides the existing owners with the tax treatment of continuing to own interests in a pass-through structure and provides potential future tax benefits for both the public company and the existing owners when they ultimately redeem their pass-through interests for shares of Class A common stock or cash from the sale of newly issued shares of Class A common stock. We will be a holding company, and upon consummation of this offering and the application of the proceeds therefrom, our principal asset will consist of LLC Interests (as defined below) we purchase directly from Fluence Energy, LLC with the net proceeds from this offering and acquire indirectly from the Blocker Shareholder (as defined below), collectively representing an aggregate 29.7% economic interest in Fluence Energy, LLC. Of the remaining 70.3% economic interest in Fluence Energy, LLC, 70.3% will be owned by the Founders through their ownership of LLC Interests. Fluence Energy, LLC intends to use the net proceeds from the sale of LLC Interests to Fluence Energy, Inc. to repay all outstanding borrowings under our existing Line of Credit and the Promissory Notes (as defined below), and the remainder for working capital and other general corporate purposes.

Fluence Energy, Inc. will be the sole managing member of Fluence Energy, LLC. We will operate and control all the business and affairs of Fluence Energy, LLC and its direct and indirect subsidiaries and, through Fluence Energy, LLC and its direct and indirect subsidiaries, conduct our business.

Following this offering, we will be a “controlled company” within the meaning of the Nasdaq rules. See “Our Organizational Structure” and “Management—Controlled Company Exception.”

We are an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended, or the Securities Act, and will be subject to reduced disclosure and public reporting requirements. This prospectus complies with the requirements that apply to an issuer that is an emerging growth company.

See “Risk Factors” beginning on page 25 to read about factors you should consider before buying shares of our Class A common stock.

Neither the Securities and Exchange Commission nor any other regulatory body has approved or disapproved of these securities or passed upon the accuracy or adequacy of this prospectus. Any representation to the contrary is a criminal offense.

We have agreed to reimburse the underwriters for certain expenses in connection with this offering. See “Underwriting.”

At our request, the underwriters have reserved for sale at the initial public offering price per share up to 5% of the shares of Class A common stock offered by this prospectus for sale at the initial public offering price through a directed share program to certain individuals identified by management. See the section titled “Underwriting—Directed Share Program.”

BNP Paribas Energy Transition Fund (“BNPP ET”) has indicated an interest in purchasing an aggregate of up to a maximum of $70 million in shares of Class A common stock in this offering at the initial public offering price. Because this indication of interest is not a binding agreement or a commitment to purchase, BNPP ET could determine to purchase more, fewer or no shares of Class A common stock in this offering, or the underwriters could determine to sell more, fewer or no shares to BNPP ET. The underwriters will receive the same discount on any of the shares of Class A common stock purchased by BNPP ET as they will on any other shares of Class A common stock sold to the public in this offering.

The underwriters have the option to purchase up to an additional 4,650,000 shares of Class A common stock from us at the initial price to public less the underwriting discount within 30 days of the date of this prospectus.

The underwriters expect to deliver the shares of Class A common stock against payment in New York, New York on �� , 2021.

Our Mission

Our mission is to transform the way we power our world for a more sustainable future.

Overview

We are enabling the global clean energy transition with market-leading energy storage products and services and digital applications for renewables and storage. We believe battery energy storage technology (“energy storage”) is at the center of this transition and is becoming even more important as more renewables are added to the grid and the transportation sector moves towards electrification. We are driving change by delivering configurable energy storage product, service, and digital application packages, as well as our AI-enabled Fluence IQ Platform to optimize renewable and third-party storage assets. Our offerings help major utilities, developers, and commercial and industrial (“C&I”) customers around the world deliver a more sustainable, reliable, and resilient electric grid in a repeatable, scalable way.

Energy storage is a key solution to the challenges facing electricity markets and transmission grids, including: electricity load variability and quality issues from increased participation of renewable energy generation; growing consumer and industrial demand for smart grid services; and localized capacity constraints on transmission networks, particularly around periods of peak demand. Energy storage is a uniquely flexible, asset that can provide multiple critical grid services, including energy shifting, peaking capacity, ancillary services, and transmission and distribution infrastructure functions. Our team has helped the industry move from a few deployments of single-function systems under 10 megawatts (“MW”), to multiple deployments of systems over 100 MW with broad functionality optimized by advanced software and digital intelligence.

Fluence is a leading pure-play provider of energy storage technology globally, and our AI-enabled Fluence IQ helps customers maximize the value and performance of single assets or entire portfolios of clean energy assets. Although we were established in January 2018 as a joint venture between Siemens and AES, members of our board of directors and leadership team were part of the founding team at AES Energy Storage that conceived and tested the world’s first lithium-ion energy storage system on an electric grid starting in 2007. Fluence has built on AES’ industry-defining work in clean energy and storage operations and Siemens’ energy technology leadership and global sales presence. The result is an agile company with a global presence solely focused on enabling the clean energy transition.

TABLE OF CONTENTS

enable cross-sales of Fluence energy storage products. Last year, we unveiled our sixth-generation technology stack (“Tech Stack”), which is the foundation of our energy storage products. The Tech Stack is comprised of our modular, factory-built hardware (“Fluence Cube”), proprietary operating system (“Fluence OS”), and AI-enabled digital platform (“Fluence IQ”). In addition to energy storage products, our offerings include delivery services and recurring operational services, as well as financing structuring services, such as energy-storage-as-a-service (“ESaaS”). Our Fluence IQ Digital Platform includes the Fluence Bidding Application, which delivers AI-powered market bidding optimization for solar, wind, and energy storage assets, including non-Fluence energy storage systems.

Guidehouse Consulting has ranked us as the leading energy storage provider since our inception, based on factors including vision, go-to-market strategy, product performance, technology, and execution. We were also ranked the leading global energy storage systems integrator by Navigant in 2018 and the largest global energy storage system integrator in a 2021 report by Clean Horizon. We won Best Commercial Technology of the Year at the 2020 S&P Global Platts Global Energy Awards for our sixth-generation Tech Stack and were named to Fast Company’s Most Innovative Companies, Energy list in 2019 and 2021. Previous generations of our technology have won the Edison Electric Institute’s annual Edison Awards (2016, 2019, and 2021).

As of September 30, 2021, we had 1.0 gigawatts (“GW”) of energy storage assets deployed and 2.7 GW of contracted backlog across 29 markets with a gross global pipeline of 14.2 GW. As of September 30, 2021, our global operational and maintenance (“O&M”) services team was providing services for 0.8 GW of energy storage assets, with a further 1.9 GW of contracted backlog, which have provided Fluence with over 290 terabytes of data on energy storage operation and performance as of June 30, 2021. As of June 30, 2021, we had $885 million of contracted backlog related to energy storage products, representing a 14% increase related to the same date last year and as of September 30, 2021 we estimated that we had between approximately $1,344 million and $1,393 million of contracted backlog related to energy storage products.

In 2020, we entered into an agreement with QFH for a $125 million investment to accelerate our growth and the global deployment of our offerings, which has included the acquisition of the software and digital intelligence platform of Advanced Microgrid Solutions (“AMS”), a leading artificial intelligence-enabled optimized bidding software for utility-scale storage and renewable generation assets, which became the Fluence Bidding Application. As of September 30, 2021, we had an aggregate of 3.1 GW of renewable energy assets using the Fluence Bidding Application and 1.6 GW of contracted backlog related to renewable and energy storage assets. We expect our services and Fluence IQ digital applications, including the Fluence Bidding Application, to expand meaningfully over the next five years and contribute increasingly to our bottom-line growth.

Our Industry and Market Opportunity

Climate change is an existential threat. Severe weather events and broader awareness of the financial implications of climate change are driving a systemic global transition away from fossil fuels towards sustainable energy systems. However, renewable generation, unlike fossil fuel generation, has no inherent storage capacity and can only be used in favorable wind and solar conditions. Energy storage is therefore a critical enabler of large-scale adoption of 24/7 renewable energy. Furthermore, accelerating electrification of industries such as transportation is driving demand for more generation. Energy storage can help both serve and smooth additional peak demand, improving grid reliability and managing energy requirements.

As the first truly digital asset on the electric grid, energy storage is also a uniquely flexible tool for grid planners, operators, and power providers. We believe energy storage sits at the epicenter of the global clean energy transition and represents the backbone of a massive change in our energy market infrastructure driven by three key trends: Grid modernization, decarbonization, and digitalization. The energy transformation will require $100 trillion of investment through 2050 based on the midpoint of Bloomberg New Energy Finance’s (“BloombergNEF”) NEO 2020 clean electricity and green hydrogen pathway.

The energy storage market is comprised of three components:

•

Energy storage products—the components (including batteries), professional services, and labor required to manufacture, assemble, and install products. According to BloombergNEF, global annual

TABLE OF CONTENTS

energy storage capacity installations, excluding the residential market, grew from 0.6 GW a year in 2015 to 3.8 GW a year in 2020, and are expected to grow to 34.2 GW a year by 2030. We believe most forecasts for the energy storage sector, including BloombergNEF, understate the size and market opportunity as forecasts generally only account for spend associated with the physical energy storage asset and do not account for the associated service and digital spend.

•

Services—recurring operational and maintenance services that energy storage products require, management services that are provided by third parties when asset owners outsource the operations of their systems, and the provision of ESaaS. According to BloombergNEF, global installed energy storage capacity, excluding the residential market, grew 57% per annum between 2015 and 2020, and the installed base is expected to grow at a 31% annual growth rate through 2030. BloombergNEF forecasts that global installed energy storage capacity will reach 193.7 GW by 2030, excluding the residential market.

•

Digital applications and solutions—operating systems, applications, such as trading platforms that allow system owners to manage their grid participation, and dynamic capacity services, such as virtual power plants. We believe there is an opportunity to not only deploy digital applications and solutions on individual assets but also across entire energy storage fleets and portfolios of generation assets to improve their collective performance and economic output, and to reduce the overall carbon footprint of the electric grid by optimizing the interactions between different asset types.

We believe there are multiple factors driving continued growth in the energy storage sector, including:

•

The accelerating transition from fossil to renewable generation is expected to require significant increases in energy storage capacity to both offset potential grid instability caused by intermittent renewable resources and enable the use of power from renewable generation assets at times when the natural resource is unavailable.

•

Growing capacity constraints on existing power grids that were not designed to support distributed and renewable generation infrastructure or technologies such as electric vehicles are positioning energy storage assets as a key solution.

•

A forecasted reduction in the battery cost, estimated by BloombergNEF to be approximately 8% annually from 2020 to 2030, is expected to improve the economics of energy storage and support the development of larger energy storage systems.

•

The levelized cost of storage (LCOS) of battery storage has decreased from an estimated $324/MWh in 2018 to an estimated $192/MWh in 2020, according to the Lazard Levelized Cost of Storage Analysis. This reduction in cost makes battery storage economically competitive with the gas peakers which are estimated in 2020 to have a levelized cost of energy (LCOE) range of $151/MWh to $198/MWh, according to the Lazard Levelized Cost of Energy Analysis.

•

Environmental responsibility has become a priority for major companies and investors, with over 300 major companies having pledged to source 100% of their energy from renewables as part of the RE100, a global corporate renewable energy initiative.

•

Governments across the globe have announced policies to support the transition from fossil fuels to low-carbon forms of energy.

Services

Operational & Maintenance Services

Energy Storage-as-a-Service

Fluence, working with third-party financial partners, including Siemens Financial Services, offers financing structuring services to customers. For instance, ESaaS enables customers to access the benefits of energy storage without upfront investment or technical expertise.

Digital Applications and Solutions

Our team is continuously expanding the digital applications we offer to customers. Those applications may include internally developed applications as well as third-party applications offered through the Fluence IQ digital applications platform.

Our proprietary operations platform, Fluence OS, enables asset owners to manage storage product operations according to pre-set modes and access real-time information through cloud-based data. It is an integral part of all our energy storage product sales. Fluence OS controls software enables Fluence energy storage products to deliver critical grid services such as primary frequency regulation, secondary frequency response, fast frequency response, peak shaving, voltage regulation, power factor regulation, non-spinning reserves, capacity peak power, solar energy time-shifting, firm solar export, energy arbitrage, and more. Fluence also delivers stacking of grid services, allowing storage assets to perform multiple services simultaneously and increase revenue-generating opportunities. In addition to Fluence OS, we offer the Fluence IQ Digital Platform with specialized digital applications that encompasses proprietary artificial intelligence and data science technologies, such as the Fluence Bidding Application.

TABLE OF CONTENTS

The Bidding Application is a leading artificial intelligence-enabled bidding software for utility-scale storage and renewable and conventional generation assets, enabling customers to optimize asset trading in wholesale electricity markets. That leadership is demonstrated by the fact that it has been selected by one customer for deployment in the California market to optimize a product acquired from a Fluence competitor. In addition, it is currently used to optimize approximately 20% of all the utility-scale wind and solar assets bidding into Australia’s National Electricity Market, including one of the largest solar farms in the country. One of the goals of the AMS acquisition is to combine Fluence’s insights from deep experience operating energy storage products globally with the Bidding Application’s optimized market participation capabilities.

Our Bidding Application is technology-agnostic (it can be applied to wind and solar assets as well as energy storage assets) and vendor-agnostic (it is available to optimize non-Fluence storage products), and it is delivered using cloud-based software-as-a-service, avoiding requirements for onsite hardware or software installations. Our pricing strategy is based on a volume-based subscription fee with the ability to start with a smaller scale and increase the number of assets covered by the software as customers build out their fleets, along with the potential for performance-based revenue-sharing structures.

Our Competitive Strengths

We believe the following key strengths have enabled us to become a leading provider of energy storage products, services, and digital applications, positioning us to continue to capture future market opportunities:

•

Incumbent position with global track record of success. We are one of the largest providers of energy storage products globally, with 1.0 GW of energy storage assets deployed and 2.7 GW of contracted backlog as of September 30, 2021, and a track record of 13 years of experience from our predecessor companies. Additionally, as of September 30, 2021, we had an aggregate of 3.1 GW of renewable energy assets using the Fluence Bidding Application and 1.6 GW of contracted backlog related to renewables and energy storage assets. Moreover, through Fluence OS, we have access to hundreds of thousands of hours of cumulative energy storage product operating history, with over 290 terabytes of data on operation and performance as of June 30, 2021. This data enables us to optimize our asset base, dispatching them to maximize economics, reduce operational costs, extend useful lives, and deliver critical grid services when needed.

•

Disruptive digital and software products. We use multi-layered design of edge and cloud applications, including Fluence OS and Fluence IQ, to transform hardware into digital assets that provide extensive market and grid services, such as the Fluence Bidding Application. Our dedicated Fluence Digital team is focused on developing and commercializing additional cloud-based applications using optimization, AI-driven predictive analytics, and software to address the challenges customers face when participating in complex energy markets.

•

Large installed base enables cross-selling and incremental revenue streams. Our installed base is a captive market for repeat customers and high-margin follow-on service and digital opportunities, as we are best positioned to provide tailored, value-maximizing solutions for our own products. The majority of our customers adopt energy storage as a new asset class and return for subsequent products purchases. We believe our substantial base of customers and data enables cross-selling of our service and digital offerings. Conversely, digital applications sold to non-Fluence energy storage product customers can enable energy storage product cross-sales. By deploying learnings from our digital application customers to develop offerings that meet their business needs, we believe we can create opportunities to convert them into product owners.

•

Global supply chain and technology partnerships. We have developed a global supply chain with an evolving regionally focused operational model with the objective of assembling products in proximity to major markets and partnering with innovative suppliers. For example, we recently signed a technology co-development and supply agreement with Northvolt that expands our battery supply chain into Europe and allows us to develop, manufacture, and commercialize an optimized battery subsystem that is significantly more energy dense than today’s standard solutions. The agreement also enables us to deploy a battery management system that we can integrate with other vendors to extend our value chain, develop battery competencies, and lower total cost of ownership.

TABLE OF CONTENTS

•

Battery technology-agnostic. Our energy storage products are designed to work with many types of batteries, and we have established partnerships with the leading battery manufacturers around the world, with approximately 20 GWh of contracted battery supply through 2024. As a result, we do not believe we are exposed to significant risk from changes in battery technology or shifts in market share between different manufacturers.

•

Experienced management team with extensive energy storage experience. We believe we have assembled one of the most experienced management teams in the energy storage sector, with over 200 years of aggregate industry experience and a proven track-record of managing high-growth, international operations for global industrial and technology companies. Members of our management and Board were on the team that conceived and tested the first ever grid-connected lithium-ion energy storage system and sold the world’s first commercial system.

Our Growth Strategy

We intend to leverage our global scale, technology leadership and market share position to help transform the way we power our world for a more sustainable future. Some key elements of our growth strategy include:

•

Develop energy products, services, and digital applications packaged into solutions that solve customers’ energy challenges. Our close relationships with customers and our market intimacy informs our hardware and software product development and service offerings and enables us to continually expand use cases for energy storage on the grid—pushing the edge of innovation for grid modernization and decarbonization as our customers’ business models evolve.

•

Expand competitive advantage of productization and manufacturing. We aim to create an optimized production organization, develop mass manufacturing facilities globally, and continue to secure partnerships with key battery suppliers. We believe that enhancing our product-focused model and supply chain leverage will support our global growth objectives and result in superior unit economics.

•

Optimize sales channels and market segmentation with a regionalized model. We are focused on expanding standardized offerings that are optimized for each of our sales channels, allowing us to streamline product procurement for our customers, improve our sales cycle, enhance our ability to scale and support our margin expansion. We are also moving to a more localized, regional organizational structure to better support customers and sales channels, improve logistics, and enhance market focus.

•

Leverage our sponsor relationships to accelerate global growth. Our partnerships with AES and Siemens provide built-in and growing customer bases and an international sales channel. In addition, in 2021, QIA became a strategic sponsor with its investment through QFH that may help position us to form relationships with additional technology partners, customers, and suppliers.

•

Expand our services with additional value-add offerings. Our delivery and operational service offerings address the diverse needs of our customers in different markets around the world. We intend to build and expand our portfolio of service offerings, including product upgrades, analysis, performance assurance, risk management products, and software support, using data-driven insights generated from our large installed base of energy storage products.

•

Accelerate the deployment of the Fluence Bidding Application and develop new Fluence IQ digital applications. Our digital offerings enable renewable and energy storage asset owners to solve the complexities of power system dispatch on a grid that remains dependent on out-of-date infrastructure and inefficient tools. We are focused on making the Fluence Bidding Application available in more markets while expanding our breadth of Fluence IQ digital application offerings, including integrated solutions for specific customer segments and new asset classes.

•

Incubate innovative business models. We continue to explore disruptive digitally-driven business models, including ESaaS, wide-ranging dynamic capacity, virtual storage, asset- and revenue-sharing models, and other offerings that will reinforce our position as a leading provider of comprehensive solutions to support the clean energy transition.

•

Ability to acquire and successfully integrate companies. We have a demonstrated track record of successfully acquiring and integrating companies, and believe we have the operational structure in place to achieve synergies and capture cross-selling opportunities. For example, within eight months of acquiring AMS, we had fully integrated the team and technology into Fluence and grown adoption of the Fluence Bidding Application software by 1.7 GW.

Environmental, Social, and Governance

We are a purpose-built, purpose-driven company on a mission to transform the way we power our world for a more sustainable future. We support the clean energy transition by enabling greater adoption of renewable energy and decarbonized technologies such as electric vehicles and reduced use of thermal generation resources. Our offerings enable more sustainable, reliable, and resilient electric grids in a repeatable, scalable way. On an annualized basis, based on MW deployed as of May 2021, we estimate that Fluence energy storage products have eliminated 145,000 metric tons of carbon per year that would have otherwise been produced—the equivalent of taking more than 30,000 cars off the road each year.

We endeavor to go beyond the inherent environmental aspects of our technology and implement sustainable and ethical processes throughout our organization. Our supplier code of conduct is at the core of our compliance expectations, and addresses environmental protection, child labor, conflict minerals, and anti-corruption, among other areas. In addition, we only purchase raw materials and minerals from trusted suppliers. In sourcing cobalt for example, we request that suppliers provide an official cobalt statement disclosing its origin, and we only buy cobalt battery chemistry from suppliers who are part of a sustainable cobalt sourcing initiative. In 2021, our supply chain sustainability coordinator engaged the Carbon Disclosure Project to conduct an audit of our supply chain’s carbon footprint.

We are committed to implementing responsible environmental and ethical practices in our corporate offices as well as our supply chain. Our offices are internationally certified to ISO 14001, which requires an organization to implement and demonstrate compliance with an effective environmental management system to identify and control the environmental impact of its activities, products, and services; continually improve environmental performance; and implement a systematic approach to setting environmental objectives and targets.

Creation of Our Company

We were created from the union of AES’ Energy Storage division and Siemens’ battery-based energy storage solutions group. The founding team at AES Energy Storage—several of whom are on Fluence’s leadership team and Board—tested the first ever lithium-ion battery energy storage system on the grid in 2007, sold the world’s first commercial grid-scale energy storage system in Chile in 2009, and subsequently amassed deep expertise in utility-scale storage solutions for flexible peaking capacity, ancillary services such as frequency regulation, transmission and distribution reliability, and renewable integration applications. Siemens’ battery-based energy storage solutions group was established in 2011, building on the company’s knowledge of customer power needs as a leading global original equipment manufacturer and developing experience in microgrid and islanding applications, renewable hybrid technology, and consumer peak shaving.

The diagram below depicts our organizational structure after giving effect to the Transactions, including this offering, assuming no exercise by the underwriters of their option to purchase additional shares of Class A common stock.

[MISSING IMAGE: tm2120236d11-fc_votingbw.jpg]

This chart does not include the 23,988,372 shares of Class A common stock issuable pursuant to our equity compensation plans.

After giving effect to the Transactions, including this offering, Fluence Energy, Inc. will be a holding company whose principal asset will consist of 29.7% of the outstanding LLC Interests of Fluence Energy, LLC (or 31.6% if the underwriters exercise in full their option to purchase additional shares of our Class A common stock). This offering is being conducted through what is commonly referred to as an “Up-C” structure, which is often used by partnerships and limited liability companies undertaking an initial public offering. The Up-C approach provides the existing owners with the tax treatment of continuing to own interests in a pass-through structure and provides potential future tax benefits for both the public company and the existing owners when they ultimately redeem their pass-through interests for shares of Class A common stock or cash from the sale of newly issued shares of Class A common stock.

Recent Developments—Preliminary Fourth Quarter Results

While we have not yet completed our closing procedures as of and for the three months and fiscal year ended September 30, 2021, set forth below are selected, unaudited, preliminary estimated results for that period.

Based on our preliminary internal estimates, we estimate new energy storage product contracts executed during the fiscal year ended September 30, 2021 will represent total contracted power of approximately 1,311 MW, compared to 844 MW of total contracted power during the fiscal year ended September 30, 2020, and new energy storage products executed during the three months ended September 30, 2021 will represent total contracted power of approximately 821 MW, compared to 279 MW of total contracted power during the three months ended September 30, 2020.

TABLE OF CONTENTS

Additionally, we estimate that for the fiscal year ended September 30, 2021, we had approximately 1,959 MW of contracted service contracts, compared to 232 MW for the fiscal year ended September 30, 2020, and for the three months ended September 30, 2021, we had approximately 749 MW of contracted service contracts, compared to 205 MW for the three months ended September 30, 2020.

For the fiscal year ended September 30, 2021, we estimate that we had approximately 2,744 MW of contracted digital contracts, compared to 0 MW for the fiscal year ended September 30, 2020, and for the three months ended September 30, 2021, we estimate that we had approximately 1,010 MW of contracted digital contracts, compared to 0 MW for the three months ended September 30, 2020.

We also estimate that our total revenue for the fiscal year ending September 30, 2021 will be between approximately $650 million and $699 million, compared to $561.3 million of total revenue for the fiscal year ended September 30, 2020, and our total revenue for the three months ending September 30, 2021 will be between approximately $158 million and $207 million, compared to $239.5 million of total revenue for the three months ended September 30, 2020, which is being driven primarily by sales of our energy storage products. Revenue for the three months and fiscal year ending September 30, 2021 has been negatively affected by impacts related to the COVID-19 global pandemic, such as delays in shipping out energy storage products and temporary closures of customer construction sites. Such delays may continue in fiscal year 2022. Please see “Risk Factors—Risks Related to our Business—We have experienced and may continue to experience delays, disruptions, or quality control problems in our manufacturing operations in part due to our third-party supplier and manufacturer concentration.” and “—We face risks related to actual or threatened health epidemics, such as the COVID-19 pandemic, and other outbreaks, which could significantly disrupt our suppliers’ manufacturing and our operations.”

As discussed elsewhere in this prospectus, we experience seasonality and typically see increased order intake in the third and fourth fiscal quarters (April to September), and we have seen that trend continue in our fiscal fourth quarter ended September 30, 2021. Please see “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors and Trends—Seasonality” and “Risk Factors—Risks Related to Our Financial Condition and Liquidity—Our order intake and cash flows have been highly seasonal, which could make our future performance difficult to predict and could cause our results of operations for a particular period to fluctuate from quarter to quarter or fall below expectations, resulting in a decline in the price of our Class A common stock” for further discussion of our seasonality.

For the three months and fiscal year ended September 30, 2021, we expect that our financial results, specifically our gross profit and gross profit as a percentage of revenue, will be negatively impacted by (a) capacity constraints within the shipping industry and increased shipping costs, both of which we believe are caused primarily as a result of the COVID-19 pandemic, and (b) cost overruns and delays we are experiencing in some projects currently under construction. Some of those costs overruns and delays are occurring in the first Generation 6 product deliveries. As a result, we expect to recognize gross loss of approximately $64 million to $75 million for the fiscal year ended September 30, 2021 compared to a gross profit of $7.9 million for the fiscal year ended September 30, 2020, and a gross loss of approximately $54 million to $65 million for the three months ended September 30, 2021 compared to a gross profit of $12 million for the three months ended September 30, 2020. We also expect to report a lower gross profit as a percentage of revenue for the three months and fiscal year ended September 30, 2021 compared to the corresponding periods of fiscal 2020. See “Risk Factors—Risks Related to Our Business—Significant changes in the cost of raw materials or to logistic cost(s) could adversely affect our financial performance” and “Risk Factors - We have experienced and may continue to experience delays, disruptions, or quality control problems in our manufacturing operations in part due to our third-party supplier and manufacturer concentration.”

We expect that the negative impacts of the items discussed below will result in a net loss of approximately $158 million to $169 million for the fiscal year ended September 30, 2021, compared to a net loss of $46.7 million for the fiscal year ended September 30, 2020, and a net loss of approximately $84 million to $95 million for the three months ended September 30, 2021, compared to a net loss of $1.1 million for the three months ended September 30, 2020.

The increased investment into our business growth, the transition to a mass manufacturing business model, the delays from shipping, and temporary customer site closures is causing negative cash flow. We

TABLE OF CONTENTS

estimate that our cash flow from operations for the fiscal year ending September 30, 2021 will be between approximately $(254) million and $(264) million, compared to $(14) million of cash flow from operations for the fiscal year ended September 30, 2020, and our cash flow from operations for the three months ending September 30, 2021 will be between approximately $(115) million and $(125) million, compared to $61.8 million of cash flow from operations for the three months ended September 30, 2020.

As of September 30, 2021, we had $100 million of indebtedness outstanding under our existing Line of Credit and the Promissory Notes.

Our preliminary estimated results for the three months and fiscal year ending September 30, 2021 are based solely on information available to us as of the date of this prospectus and are inherently uncertain and subject to change due to a variety of business, economic and competitive risks and uncertainties, many of which are not within our control, and we undertake no obligation to update this information. Our estimates contained in this prospectus are forward looking statements. These estimates should not be viewed as a substitute for our full interim or annual financial statements prepared in accordance with GAAP. Accordingly, you should not place undue reliance on this preliminary data. Our actual results may differ materially from these estimates due to financial results for the remainder of the fiscal year, the completion of our year-end closing procedures, final adjustments and developments that may arise between now and the time our financial results for the three months and fiscal year ended September 30, 2021 are finalized. Our actual consolidated financial statements and related notes for the year ended September 30, 2021 are not expected to be filed with the SEC until after this offering is completed. During the course of the preparation of these actual consolidated financial statements and related notes, additional items that may require material adjustments to the preliminary estimated financial results presented above could be identified.

The preliminary financial data included in this prospectus have been prepared by and are the responsibility of our management.

Additional Updates

As discussed in our condensed consolidated financial statements for the nine months ended June 30, 2021 contained within this prospectus, we were notified on April 28, 2021 of an emergency aboard a vessel carrying Fluence inventory. This incident resulted in damage to a portion of our cargo aboard the vessel. We recorded a gross inventory loss of $19.8 million during the nine months ended June 30, 2021 based on our best preliminary estimate of the net realizable value of the cargo. Subsequent to the issuance of our condensed consolidated financial statements for the nine months ended June 30, 2021, we have revised our estimate of gross inventory losses to $11.4 million based on further inspection and assessment of the damaged inventory. In addition to the inventory losses, we have incurred and expect to incur incremental expenses related to the incident, primarily consisting of inspection costs, project cost overruns due to logistical changes, legal fees and fees to dispose of the damaged cargo. The amount of these incremental expenses incurred during the fiscal year ended September 30, 2021 were approximately $9.4 million (subject to adjustment based on finalization of our financial results for fiscal year 2021), and we expect to incur at least an additional $2.9 million during the fiscal year ended September 30, 2022. We still expect insurance receivables of at least $10.0 million related to non-disputed claims that we believe are probable of collection.

On September 4, 2021, a 300 MW energy storage facility owned by one of our customers experienced an overheating event. Fluence served as the energy storage technology provider and installed the facility, which was completed earlier in fiscal year 2021. No injuries were reported from the incident. The facility has been taken offline as teams from Fluence, our customer, and the battery manufacturer investigate the incident. We are currently not able to estimate the impact, if any, that this incident may have on our reputation or financial results, or on market adoption of our products.

•

we have experienced and may continue to experience delays, disruptions, or quality control problems in our manufacturing operations in part due to our third-party supplier and manufacturer concentration;

•

we have experienced and may continue to experience exposure to risks associated with construction, utility interconnection, cost overruns, and delays, including those related to obtaining government permits and other contingencies that may arise in the course of completing installations;

•

the interruption of the flow of components and materials from international vendors could disrupt our supply chain, including as a result of the imposition of additional duties, tariffs, and other charges on imports and exports;

•

significant changes in the cost of raw materials or to logistic cost could adversely affect our financial performance;

•

if any energy storage products provided to our customers contain manufacturing defects, our business and financial results could be adversely affected;

•

a loss of one or more of our significant customers, their inability to perform under their contracts, or their default in payment could harm our business and negatively impact revenue, results of operations, and cash flow;

•

if we fail to manage our recent and future growth effectively, we may be unable to execute our business plan, maintain high levels of customer service, or adequately address competitive challenges;

•

we depend on our senior management team and other key employees, and the loss of one or more of these employees or an inability to attract and retain other highly skilled employees could harm our business;

•

if renewable energy technologies are not suitable for widespread adoption or sufficient demand for our hardware and software-enabled services does not develop or takes longer to develop than we anticipate, our sales may decline and we may be unable to achieve or sustain profitability;

•

if we are unable to obtain, maintain, and enforce intellectual property protection for our technology or if the scope of our intellectual property protection is not sufficiently broad, others may be able to develop and commercialize technology substantially similar to ours, and our ability to successfully commercialize our technology may be adversely affected;

•

we have made and expect to continue to make acquisitions, and if we fail to successfully select, execute, or integrate our acquisitions, then our business and operating results could be harmed and our stock price could decline;

•

we are controlled by the Continuing Equity Owners, whose interests may differ from those of our public stockholders;

•

the Tax Receivable Agreement we will enter into with the Founders requires us to make cash payments to them in respect of certain tax benefits to which we may become entitled, and we expect that such payments will be substantial; and

•

the services that we receive from the Founders may not be sufficient for us to operate our business, and we would likely incur significant incremental costs if we lost access to our Founders’ services.

Before you invest in our Class A common stock, you should carefully consider all the information in this prospectus, including as set forth in the section titled “Risk Factors.”

Implications of Being an Emerging Growth Company

We qualify as an “emerging growth company” as defined in the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). An emerging growth company may take advantage of certain reduced reporting and other requirements that are otherwise generally applicable to public companies. As a result:

•

we are required to have only two years of audited financial statements and only two years of related selected financial data and management’s discussion and analysis of financial condition and results of operations disclosure;

•

we are not required to engage an auditor to report on our internal control over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act of 2002 (the “Sarbanes-Oxley Act”);

•

we are not required to comply with the requirement of the Public Company Accounting Oversight Board regarding the communication of critical audit matters in the auditor’s report on the financial statements;

•

we are not required to submit certain executive compensation matters to stockholder advisory votes, such as “say-on-pay,” “say-on-frequency,” and “say-on-golden parachutes;” and

•

we are not required to comply with certain disclosure requirements related to executive compensation, such as the requirement to present a comparison of our Chief Executive Officer’s compensation to our median employee compensation.

We have elected to take advantage of certain of these reduced disclosure obligations in the registration statement of which this prospectus forms a part. We may take advantage of these reduced reporting and other requirements until such time that we are no longer an emerging growth company. We will remain an emerging growth company until the earliest of: (1) the last day of the fiscal year following the fifth anniversary of the consummation of this offering; (2) the last day of the fiscal year in which we have total annual gross revenue of at least $1.07 billion; (3) the last day of the fiscal year in which we are deemed to be a “large accelerated filer” as defined in Rule 12b-2 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which would occur if the market value of our common stock held by non-affiliates exceeded $700.0 million as of the last business day of the second fiscal quarter of such year; or (4) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the prior three-year period.

In addition, the JOBS Act permits an emerging growth company like us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to take advantage of this extended transition period. As a result, the information that we provide to stockholders may be different than the information you may receive from other public companies in which you hold equity.

Each share of our Class A common stock entitles its holders to one vote per share, each share of our Class B-1 common stock entitles its holders to five votes per share and each share of our Class B-2 common stock entitles its holders to one vote per share on all matters presented to our stockholders generally.

TABLE OF CONTENTS

time) on the date that is seven years following the closing of the offering. See “Description of Capital Stock.”

Redemption rights of holders of LLC Interests

The Founders may, subject to certain exceptions, from time to time at each of their options require Fluence Energy, LLC to redeem all or a portion of their LLC Interests in exchange for, at our election (determined solely by our independent directors (within the meaning of the rules of Nasdaq) who are disinterested), newly-issued shares of our Class A common stock on a one-for-one basis or a cash payment from the sale of newly issued shares of Class A common stock equal to a volume weighted average market price of one share of our Class A common stock for each LLC Interest so redeemed, in each case, in accordance with the terms of the Fluence Energy LLC Agreement; provided that, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), we may effect a direct exchange by Fluence Energy, Inc. of such Class A common stock or such cash, as applicable, for such LLC Interests. In the event of cash settlement, Fluence Energy, Inc. would issue new shares of Class A common stock and use the proceeds from the sale of these newly-issued shares of Class A common stock to fully fund the cash settlement, which, in effect, limits the amount of the cash payment to the redeeming member. Such Founders may, subject to certain exceptions, exercise such redemption right for as long as their LLC Interests remain outstanding. See “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement.” Simultaneously with the payment of cash or shares of Class A common stock, as applicable, in connection with a redemption or exchange of LLC Interests pursuant to the terms of the Fluence Energy LLC Agreement, a number of shares of our Class B-1 common stock or Class B-2 common stock, as the case may be, registered in the name of the redeeming or exchanging Founder will automatically be transferred to the Company and will be cancelled for no consideration on a one-for-one basis with the number of LLC Interests so redeemed or exchanged.

Use of proceeds

We estimate, based upon an assumed initial public offering price of $22.50 per share (which is the midpoint of the estimated price range set forth on the cover page of this prospectus), that we will receive net proceeds from this offering of approximately $650.9 million (or $750.0 million if the underwriters exercise in full their option to purchase additional shares of Class A common stock), after deducting the underwriting discount and estimated offering expenses payable by us. We intend to use the net proceeds from this offering to purchase 31,000,000 newly issued LLC Interests (or 35,650,000 LLC Interests if the underwriters exercise in full their option to purchase additional shares of Class A common stock) directly from Fluence Energy, LLC at a price per unit equal to the initial public offering price per share of Class A common stock in this offering less the underwriting discount and estimated offering expenses payable by us. Fluence Energy,

TABLE OF CONTENTS

LLC intends to use the net proceeds from the sale of LLC Interests to Fluence Energy, Inc. to repay all outstanding borrowings under our existing Line of Credit and the Promissory Notes, and the remainder for working capital and other general corporate purposes. Fluence Energy, LLC will bear or reimburse Fluence Energy, Inc. for all of the expenses of this offering. See “Use of Proceeds.”

Dividend policy

We currently intend to retain all available funds and any future earnings to fund the development and growth of our business, and therefore, we do not anticipate declaring or paying any cash dividends on our Class A common stock in the foreseeable future. Holders of our Class B-1 and Class B-2 common stock are not entitled to participate in any dividends declared by our board of directors. Because we are a holding company, our ability to pay cash dividends on our Class A common stock depends on our receipt of cash distributions from Fluence Energy, LLC and, through Fluence Energy, LLC, cash distributions and dividends from our other direct and indirect subsidiaries. Assuming Fluence Energy, LLC makes distributions out of earnings and profits (other than tax distributions and other distributions to pay expenses) to its members in any given year, we currently expect, subject to the determination of our board of directors, to pay dividends on our Class A common stock out of the portion of such distributions remaining after our payment of taxes, Tax Receivable Agreement payments and expenses, and subject to Delaware law. Our ability to pay dividends may be restricted by the terms of any future credit agreement or any future debt or preferred equity securities of us or our subsidiaries. Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors, subject to compliance with contractual restrictions and covenants in the agreements governing our future indebtedness. Any such determination will also depend upon our business prospects, results of operations, financial condition, cash requirements and availability, industry trends, and other factors that our board of directors may deem relevant. See “Dividend Policy.”

Controlled company
exception

After the consummation of the Transactions, we will be considered a “controlled company” within the meaning of the listing rules of the Nasdaq Global Market, or the Nasdaq rules, as the Continuing Equity Owners will have more than 50% of the voting power for the election of directors. See “Principal Stockholders.” As a “controlled company,” we will not be subject to certain corporate governance requirements, including that: (1) a majority of our board of directors consists of “independent directors,” as defined under the Nasdaq rules; (2) our board of directors have a compensation committee that is comprised entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and (3) our director nominations be made, or recommended to our full board of directors, by our independent directors or by a nominations committee that is

TABLE OF CONTENTS

comprised entirely of independent directors and that we adopt a written charter or board resolution addressing the nominations process. As a result, we may not have a majority of independent directors on our board of directors, an entirely independent nominating and corporate governance committee, an entirely independent compensation committee or perform annual performance evaluations of the nominating and corporate governance and compensation committees unless and until such time as we are required to do so.

Directed Share Program

At our request, the underwriters have reserved up to 5.0% of the shares of Class A common stock offered by this prospectus for sale at the initial public offering price through a directed share program to certain individuals identified by management. Any shares sold under the directed share program will not be subject to the terms of any lock-up agreement, except in the case of shares purchased by our officers or directors. The number of shares of Class A common stock available for sale to the general public will be reduced by the number of reserved shares sold to these individuals. Any reserved shares not purchased by these individuals will be offered by the underwriters to the general public on the same basis as the other shares of Class A common stock offered under this prospectus. See the section titled “Underwriting—Directed Share Program.”

Tax Receivable Agreement

We will enter into a Tax Receivable Agreement with Fluence Energy, LLC and the Founders that will provide for the payment by Fluence Energy, Inc. to such Founders of 85% of the amount of tax benefits, if any, that Fluence Energy, Inc. actually realizes (or in some circumstances is deemed to realize) as a result of (1) increases in our proportionate share of the tax basis of the assets of Fluence Energy, LLC and its subsidiaries resulting from future redemptions or exchanges (or deemed exchanges in certain circumstances) of LLC Interests by the Founders for Class A common stock or cash from the sale of newly issued shares of Class A common stock as described above under “—Redemption rights of holders of LLC Interests” and certain distributions (or deemed distributions) by Fluence Energy, LLC; and (2) certain additional tax benefits arising from payments made under the Tax Receivable Agreement. Following this offering, we expect to use distributions from Fluence Energy, LLC to fund any payments that we will be required to make under the Tax Receivable Agreement. We anticipate funding ordinary course payments under the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under any future debt agreements. Our obligations under the Tax Receivable Agreement could have a substantial negative effect on our liquidity. See “Certain Relationships and Related Party Transactions—Tax Receivable Agreement” for a discussion of the Tax Receivable Agreement.

Registration rights agreement

Pursuant to the Registration Rights Agreement, we will, subject to the terms and conditions thereof, agree to register the resale of the shares of our Class A common stock that are

TABLE OF CONTENTS

held by, issued or issuable to the Continuing Equity Owners. See “Certain Relationships and Related Party Transactions—Registration Rights Agreement” for a discussion of the Registration Rights Agreement.

Indication of Interest

BNPP ET has indicated an interest in purchasing an aggregate of up to a maximum of $70 million in shares of Class A common stock in this offering at the initial public offering price. Because this indication of interest is not a binding agreement or a commitment to purchase, BNPP ET could determine to purchase more, fewer or no shares of Class A common stock in this offering, or the underwriters could determine to sell more, fewer or no shares to BNPP ET. The underwriters will receive the same discount on any of the shares of Class A common stock purchased by BNPP ET as they will on any other shares of Class A common stock sold to the public in this offering.

Risk factors

See “Risk Factors” beginning on page 25 and other information included in this prospectus for a discussion of factors you should carefully consider before deciding to invest in shares of our Class A common stock.

Trading symbol

We have applied to list our Class A common stock on The Nasdaq Global Market under the symbol “FLNC.”

Unless we indicate otherwise or the context otherwise requires, all information in this prospectus:

•

gives effect to the amendment and restatement of the Fluence Energy LLC Agreement that converts all existing ownership interests in Fluence Energy, LLC into 117,173,390 LLC Interests, as well as the filing of our amended and restated certificate of incorporation;

•

gives effect to the other Transactions, including the consummation of this offering;

•

excludes 23,988,371 shares of Class A common stock reserved for issuance under options issued pursuant to the Existing Equity Plan (as defined below) which will convert upon effectiveness of this offering into options to acquire shares of Class A common stock, or shares of Class A common stock reserved for issuance under our 2021 Equity Plan, or the 2021 Plan or shares of Class A common stock that may be issued in respect of awards under the Existing Phantom Equity Plan (as defined below);

•

assumes an initial public offering price of $22.50 per share of Class A common stock, which is the midpoint of the estimated price range set forth on the cover page of this prospectus; and

•

assumes no exercise by the underwriters of their option to purchase 4,650,000 additional shares of Class A common stock from us.

Summary Historical and Pro Forma Condensed Consolidated Financial and Other Data

The following tables present the summary historical consolidated financial and other data for Fluence Energy, LLC and its subsidiaries and the summary pro forma consolidated financial and other data for Fluence Energy, LLC.

Fluence Energy, Inc. was formed as a Delaware corporation on June 21, 2021 and does not have historical financial results. Fluence Energy, Inc. currently has no assets or liabilities and has conducted no operations, and has not, to date, conducted any activities other than those incident to its formation, those in preparation for the Transactions and the preparation of this prospectus and the registration statement of which this prospectus forms a part. The summary consolidated statements of operations data and statements of cash flows data for the years ended September 30, 2020 and 2019, and the summary consolidated balance sheet data as of September 30, 2020 and 2019 are derived from the audited consolidated financial statements of Fluence Energy, LLC included elsewhere in this prospectus. We have derived the summary consolidated statements of operations and cash flows data for the nine months ended June 30, 2021 and June 30, 2020 from our unaudited condensed consolidated financial statements included elsewhere in this prospectus. Our summary consolidated balance sheet data as of June 30, 2021 has been derived from our unaudited condensed consolidated financial statements for such period included elsewhere in this prospectus. The unaudited consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and, in the opinion of management, include all adjustments, consisting only of normal and recurring adjustments, necessary for a fair statement of the information set forth herein. Interim financial results are not necessarily indicative of results for the full year or any future reporting period.

The unaudited pro forma consolidated balance sheet as of June 30, 2021 presents the consolidated financial position of Fluence Energy, LLC after giving pro forma effect to the Transactions, excluding this offering, and Fluence Energy, Inc. adjusted for this offering and the contemplated use of the net proceeds from this offering as described under “Our Organizational Structure” and “Use of Proceeds” as if such transactions had occurred as of the balance sheet date.

The pro forma adjustments are based on available information and upon assumptions that our management believes are reasonable in order to reflect, on a pro forma basis, the impact of the Transactions, excluding this offering, and as further adjusted for this offering, on the historical financial information of Fluence Energy, LLC. The unaudited pro forma consolidated financial information is subject to change based on the actual initial public offering price, the number of common shares sold in this offering, and other terms of this offering determined at pricing. The unaudited pro forma consolidated financial information is included for informational purposes only and does not purport to reflect the results of operations or financial position of Fluence Energy, Inc. that would have occurred had it operated according to the organizational structure set forth herein to be in place post-offering as a standalone public company during the periods presented.

RISK FACTORS

Investing in our Class A common stock involves a high degree of risk. You should carefully consider the risks and uncertainties described below, together with all of the other information in this prospectus, including our consolidated financial statements and the related notes, before deciding to invest in our Class A common stock. The occurrence of any of the events described below could harm our business, operating results, and financial condition. In such an event, the market price of our Class A common stock could decline, and you may lose all or part of your investment. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business. See “Cautionary Note Regarding Forward-Looking Statements.”

Risks Related to Our Business

Our limited operating and revenue history as an independent entity and our nascent industry make evaluating our business and future prospects difficult.

We were established in January 2018 as a joint venture between Siemens and AES. Since then, we have continued to evolve, including through acquisitions. While both AES and Siemens had approximately ten years of experience in battery-based energy storage before combining those businesses to create Fluence, and we benefit from the industry experience and substantial support AES and Siemens provide, we have a limited history operating our business and generating revenue as an independent entity, and therefore a limited history upon which you can base an investment decision.

Our future growth is dependent on rising demand for clean electric power solutions that can provide electric power with lower carbon emissions and replacement of conventional generation sources and the adoption speed of digital software applications to modernize the efficiency of power assets and the electric grid. Among other renewable energy market trends, we expect our business results to be driven by declines in the cost of generation of renewable power, decreases in the cost of manufacturing battery pack products, customer needs for services and digital applications, commercial, legal and political pressure for the reduced use of fossil fuels and electric power generation that relies on fossil or other non-renewable fuels, and a rapidly growing energy storage market driven by increasing demand from C&I customers, utilities, and grid operators. However, predicting our future revenue and appropriately budgeting for our expenses is difficult, and we have limited insight into trends that may emerge and affect our business.

If we are unable to attract new customers and retain existing customers, our revenue growth will be adversely affected.

To increase our revenue, our business strategy depends on our ability to attract new customers and retain existing customers. We face competition from other energy storage and digital application providers in the recruitment of potential customers. If we are unable to convince potential customers of the benefits of our services or if potential or existing customers prefer the product and service offerings of one of our competitors, we may not be able to effectively implement our growth strategy. Additionally, a significant portion of our annual sales were direct sales to AES or a result of our Siemens sales relationship. See Note 13 to our unaudited consolidated financial statements for the nine months ended June 30, 2021, “Related Party Transactions.” If we fail to maintain those relationships, or if AES or Siemens decide to reduce their energy storage activities in the future, it could impact our sales and our growth would be even more reliant on our ability to recruit new customers. Our inability to recruit new customers and retain existing customers would harm our ability to execute our growth strategy and may have a material adverse effect on our business operations and financial position.

We have experienced and may continue to experience delays, disruptions, or quality control problems in our manufacturing operations in part due to our third-party supplier and manufacturer concentration.

Our product development, manufacturing and testing protocols are complex and require significant technological and production process expertise, and we currently depend on a limited number of third-party manufacturers, including for batteries and other key components of our products. In addition to concentration in our supply chain for batteries and other components, as of today, we have one major

TABLE OF CONTENTS

contract manufacturer for the Fluence Cube and are planning to expand our set of partners in the near term. As we introduce new products, we plan to expand our supply chain and regional manufacturing capabilities to further support customers in APAC, EMEA, and the Americas. While the risks of relying on a single Cube vendor and a limited number of suppliers for batteries and other components will diminish with regional and footprint optimization, expansion may be delayed by the process of vetting and qualifying new suppliers and manufacturing partners. Further, any vendor delay or disruption could cause a delay or disruption in our ability to meet customer requirements which may result in a loss of customers. Such processes involve a number of precise steps from design to production.

Any change in our processes could cause one or more production errors, requiring a temporary suspension or delay in our production line until the errors can be researched, identified, and properly addressed and rectified. This may occur particularly as we introduce new products, modify our engineering and production techniques, and/or expand our capacity. In addition, our failure to maintain appropriate quality assurance processes could result in increased product failures, loss of customers, increased warranty reserve, or increased production and logistics costs, and delays. Any of these developments could have a material adverse effect on our business, financial condition, and results of operations.

We have experienced and may continue to experience exposure to risks associated with construction, utility interconnection, cost overruns, and delays, including those related to obtaining government permits and other contingencies that may arise in the course of completing installations.

Although we generally are not regulated as a utility, federal, state, and local government statutes and regulations concerning electricity heavily influence the market for our product and services. These statutes and regulations often relate to electricity pricing, net metering, incentives, taxation, and the rules surrounding the interconnection of customer-owned electricity generation for specific technologies. In the U.S., governments frequently modify these statutes and regulations. Governments, often acting through state utility or public service commissions, change and adopt different requirements for utilities and rates for commercial customers on a regular basis. Changes, or in some cases a lack of change, in any of the laws, regulations, ordinances, or other rules that apply to customer installations and new technology could make it more costly for our customers to install and operate our energy storage products on particular sites, and in turn could negatively affect our ability to deliver cost savings to customers for the purchase of electricity.

The installation and operation of our energy storage products at a particular site are also generally subject to oversight and regulation in accordance with national, state, and local laws and ordinances relating to building codes, safety, environmental protection, and related matters, and typically require obtaining and keeping in good standing various local and other governmental approvals and permits, including environmental approvals and permits, that vary by jurisdiction. In some cases, these approvals and permits require periodic renewal. It is difficult and costly to track the requirements of every individual authority having jurisdiction over energy storage product installations, to design our energy storage products to comply with these varying standards, and for our customers to obtain all applicable approvals and permits. We cannot predict whether or when all permits required for a given customer’s project will be granted or whether the conditions associated with the permits will be achievable. The denial of a permit or utility connection essential to a project or the imposition of impractical conditions would impair our customer’s ability to develop the project. In addition, we cannot predict whether the permitting process will be lengthened due to complexities and appeals. Delay in the review and permitting process for a project can impair or delay our customers’ abilities to develop that project or increase the cost so substantially that the project is no longer attractive to our customers. Furthermore, unforeseen delays in the review and permitting process could delay the timing of the installation of our energy storage products and could therefore adversely affect the timing of the recognition of revenue related to hardware acceptance by our customer, which could adversely affect our operating results in a particular period.

The production and installation of our energy storage products also involves the incurrence of various project costs and can entail project modifications. We have policies and procedures regarding the approval of project costs and modifications. In connection with our limited operating history and our significant growth, we have in the past experienced and may in the future experience incurrence of project costs without proper documentation or adhering to our policies and procedures. We have implemented additional training on our policies and procedures in this regard. In addition, disagreements with our customers and

TABLE OF CONTENTS

suppliers have arisen and may in the future arise with respect to project schedules, work and modifications, which can result in the need to find different suppliers, loss of future business, additional costs to us and not realizing the anticipated profit from the project.

In addition, the successful installation of our energy storage products is dependent upon the availability of and timely connection to the local electric grid. Our customers may be unable to obtain the required consent and authorization of local utilities to ensure successful interconnection to energy grids to enable the successful discharge of renewable energy. Any delays in our customers’ ability to connect with utilities, delays in the performance of installation-related services, or poor performance of installation-related services will have an adverse effect on our results and could cause operating results to vary materially from period to period.

The interruption of the flow of components and materials from international vendors could disrupt our supply chain, including as a result of the imposition of additional duties, tariffs, and other charges on imports and exports.

We purchase some of our components and materials outside of the United States through arrangements with various vendors, and have experienced delays in obtaining these components and materials as a result of the recent coronavirus pandemic (“COVID-19 pandemic”). Political, social, or economic instability in these regions, or in other regions where our products are made, could cause future disruptions in trade. Actions in various countries have created uncertainty with respect to tariff impacts on the costs of some of our components and materials. The degree of our exposure is dependent on (among other things) the type of materials, rates imposed, and timing of the tariffs. Other events that could also cause disruptions to our supply chain include:

•

the imposition of additional trade law provisions or regulations;

•

the imposition of additional duties, tariffs and other charges on imports and exports, including as a result of the escalating trade war between China and the United States;

•

quotas imposed by bilateral trade agreements;

•

foreign currency fluctuations;

•

logistics and shipping constraints;

•

natural disasters;

•

public health issues and epidemic diseases, their effects (including any disruptions they may cause) or the perception of their effects;

•

theft;

•

restrictions on the transfer of funds;

•

the financial instability or bankruptcy of vendors; and

•

significant labor disputes, such as dock strikes.

We cannot predict whether the countries in which our components and materials are sourced, or may be sourced in the future, will be subject to new or additional trade restrictions imposed by the United States or other foreign governments, including the likelihood, type, or effect of any such restrictions. Trade restrictions, including new or increased tariffs or quotas, border taxes, embargoes, safeguards, and customs restrictions against certain components and materials, as well as labor strikes and work stoppages or boycotts, could increase the cost or reduce or delay the supply of components and materials available to us and adversely affect our business, financial condition or results of operations.

Significant changes in the cost of raw materials or to logistic cost could adversely affect our financial performance.

We are subject to risk from fluctuating market prices of certain commodity raw materials, including steel and aluminum, that are used in our products. Prices of these raw materials may be affected by supply restrictions or other logistic costs market factors from time to time, and we do not enter into hedging

TABLE OF CONTENTS

arrangements to mitigate commodity risk. Significant price changes for these raw materials could reduce our operating margins if we are unable to recover such increases from our customers, and could harm our business, financial condition, and results of operations.

Failure by our vendors or our component or raw material suppliers to use ethical business practices and comply with applicable laws and regulations may adversely affect our business.

We do not control our vendors or suppliers or their business practices. Accordingly, we cannot guarantee that they follow ethical business practices, such as fair wage practices and compliance with environmental, safety, and other local laws. A lack of demonstrated compliance could lead us to seek alternative manufacturers or suppliers, which could increase our costs and result in delayed delivery of our products, product shortages, or other disruptions of our operations. Violation of labor or other laws by our manufacturers or suppliers or the divergence of a supplier’s labor or other practices from those generally accepted as ethical in the U.S. or other markets in which we do business could also attract negative publicity for us and harm our business.

We face supply chain competition and, in some instances, have entered into long-term supply agreements that could result in insufficient inventory and negatively affect our results of operations.

We have entered into long-term supply agreements with certain suppliers and contract manufacturers of batteries, inverters, and other components of our energy storage products. Some of these supply agreements provide for fixed or inflation-adjusted pricing, substantial prepayment obligations, and commitments to continue purchasing certain levels of components in future periods regardless of the level of demand we receive from customers. If our suppliers provide insufficient inventory at the level of quality required to meet customer demand, or if our suppliers are unable or unwilling to provide us with the contracted quantities, as we have limited alternatives for supply in the short term, our results of operations could be materially and negatively impacted. If our customers do not provide sufficient demand to purchase the levels of inventory we have committed to purchasing in future periods, our ability to generate revenue or cash flows may be limited.

Further, we face significant specific counterparty risk under long-term supply agreements when dealing with certain suppliers without a long, stable production and financial history. Given the uniqueness of our product, many of our suppliers do not have a long operating history and may not have substantial capital resources. In the event any such supplier experiences financial difficulties, it may be difficult or may require substantial time and expense to replace such supplier. We do not know whether we will be able to maintain long-term supply relationships with our critical suppliers, or secure new long-term supply agreements. Additionally, many of the battery storage products and components of our energy storage products are procured from foreign suppliers, which exposes us to risks including unforeseen increases in costs or interruptions in supply arising from changes in applicable international trade regulations, such as taxes, tariffs, or quotas. Any of the foregoing could materially adversely affect our business, financial condition, and results of operations.

Certain of our suppliers also supply products and components to other businesses, including businesses engaged in the production of electric vehicles, consumer electronics and other industries unrelated to energy storage products. As a relatively low-volume purchaser of certain of these parts and materials, we may be unable to procure a sufficient supply of the items on favorable terms or at all, in the event that our suppliers fail to produce sufficient quantities to satisfy the demands of all of their customers, which could materially adversely affect our business, financial condition, and results of operations.

If any energy storage products provided to our customers contain manufacturing defects, our business and financial results could be adversely affected.

The energy storage products we develop are complex energy solutions. We rely on our component OEM suppliers and contract manufacturers to control the quality of certain components that make up the energy storage products sold to our customers. We do not manufacture the batteries or other components of the energy storage products. As a result, our ability to seek recourse for liabilities and recover costs from our component OEM suppliers and contract manufacturers depends on our contractual rights as well as the financial condition and integrity of such component OEM suppliers and contract manufacturers that

TABLE OF CONTENTS

supply us with the batteries and other components of our energy storage products. Such products may contain undetected or latent errors or defects. We provide installation, construction and commissioning services for our customers that purchase our products. In the past, we have from time to time discovered latent defects in energy storage products, and have experienced defects in workmanship. In connection with such defects in the future, we could incur significant expenses or disruptions of our operations. Any manufacturing defects or other failures of our energy storage products to perform as expected could cause us to incur significant re-engineering costs, divert the attention of our personnel from operating and maintenance efforts, expose us to adverse regulatory action, and significantly and adversely affect customer satisfaction, market acceptance, and our business reputation. Furthermore, our component OEM suppliers and contract manufacturers may be unable to correct manufacturing defects or other failures of any energy storage products in a manner satisfactory to our customers, which could adversely affect customer satisfaction, market acceptance, and our business reputation.

On rare occasions, lithium-ion batteries can rapidly release the energy they contain by venting smoke and flames in a manner that can ignite nearby materials as well as other lithium-ion batteries. This faulty result could subject us to lawsuits, product recalls, or redesign efforts, all of which would be time consuming and expensive. For example, in April 2019, the McMicken energy storage facility in Arizona experienced a thermal event and subsequent explosion, injuring several first responders and making the facility inoperable. The facility was built by AES prior to the creation of Fluence, and was under a maintenance contract with Fluence. The response and investigation required significant expense and the devotion of significant management time. Also, negative public perceptions regarding the suitability of lithium-ion batteries for energy applications or any future incident involving lithium-ion batteries, such as a plant, vehicle or other fire, even if such incident does not involve hardware provided by us, could adversely affect our business and reputation.

A loss of one or more of our significant customers, including but not limited to AES and Siemens, their inability to perform under their contracts, or their default in payment could harm our business and negatively impact revenue, results of operations, and cash flow.

We are dependent on a relatively small number of customers for our sales, and a small number of customers have historically accounted for a material portion of our revenue. The loss of any one of the Company’s significant customers, their inability to perform under their contracts, or their default in payment could have a materially adverse effect on the revenues and profits of the Company. For the near future, we may continue to derive a significant portion of our net sales from a small number of customers. For the year ended September 30, 2020, our top five customers, in the aggregate, accounted for approximately 90% of our revenue. Accordingly, loss of a significant customer or a significant reduction in pricing or order volume from a significant customer could materially reduce net sales and operating results in any reporting period.

If we fail to manage our recent and future growth effectively, we may be unable to execute our business plan, maintain high levels of customer service, or adequately address competitive challenges.

We have experienced significant growth in recent periods. We intend to continue to expand our business significantly within existing and new market segments. This growth has placed, and any future growth may place, a significant strain on our management, operational, and financial infrastructure. In particular, we will be required to expand, train, and manage our growing employee base and scale and otherwise improve our IT infrastructure in tandem with that headcount growth. Our management will also be required to maintain and expand our relationships with customers, suppliers, channel partners, and other third parties and attract new customers and suppliers, as well as manage multiple geographic locations. Our current and planned operations, personnel, IT, and other systems and procedures might be inadequate to support our future growth and may require us to make additional unanticipated investment in our infrastructure. Our success and ability to further scale our business will depend, in part, on our ability to manage these changes in a cost-effective and efficient manner. If we cannot manage our growth, we may be unable to take advantage of market opportunities, execute our business strategies, or respond to competitive pressures. This could also result in declines in quality or customer satisfaction, increased costs, difficulties in introducing new offerings, or other operational difficulties. Any failure to effectively manage growth could adversely impact our business and reputation.

TABLE OF CONTENTS

If we are not able to maintain and enhance our reputation and brand recognition, our business and results of operations will be harmed.

We believe that maintaining and enhancing our reputation and brand recognition is critical to our relationships with customers. The promotion of our brand may require us to make substantial investments, and we anticipate that, as our market becomes increasingly competitive, these marketing initiatives may become increasingly difficult and expensive. Our marketing activities may not be successful or yield increased revenue, and to the extent that these activities yield increased revenue, the increased revenue may not offset the expenses we incur, and our results of operations could be harmed. In addition, any factor that diminishes our reputation or that of our management, including failing to meet the expectations of or provide quality products and services to our customers, or any adverse publicity or litigation involving or surrounding us, one of our centers, or our management, could make it substantially more difficult for us to attract new customers. If we do not successfully maintain and enhance our reputation and brand recognition, our business may not grow, and we could lose our relationships with customers, which would harm our business, results of operations, and financial condition.

Our growth depends in part on the success of our relationships with third parties.

We rely on third-party general contractors to install energy storage products at our customers’ sites. We currently work with a limited number of general contractors, which has impacted and may continue to impact our ability to facilitate customer installations as planned. Our work with contractors or their subcontractors may have the effect of our being required to comply with additional rules (including rules unique to our customers), working conditions, site remediation, and other union requirements, which can add costs and complexity to an installation project. The timeliness, thoroughness, and quality of the installation-related services performed by our general contractors and their subcontractors in the past have not always met our expectations or standards and in the future may not meet our expectations and standards, and it may be difficult to find and train third-party general contractors that meet our standards at a competitive cost.

In addition, a key component of our growth strategy is to develop or expand our relationships with third parties. For example, we are investing resources in establishing strategic relationships with market players across a variety of industries, including large renewable project developers, to generate new customers. These programs may not roll out as quickly as planned or produce the results we anticipated. A significant portion of our business depends on attracting new counterparties and retaining existing counterparties. Negotiating relationships with our counterparties, investing in due diligence efforts with potential counterparties, training such third parties and contractors, and monitoring them for compliance with our standards requires significant time and resources and may present greater risks and challenges than expanding a direct sales or installation team. If we are unsuccessful in establishing or maintaining our relationships with these third parties, our ability to grow our business and address our market opportunity could be impaired. Even if we are able to establish and maintain these relationships, we may not be able to execute on our goal of leveraging these relationships to meaningfully expand our business, brand recognition and customer base. Such circumstance would limit our growth potential and our opportunities to generate significant additional revenue or cash flows.

We depend on our senior management team and other key employees, and the loss of one or more of these employees or an inability to attract and retain other highly skilled employees could harm our business.

Our success depends largely upon the continued services of our senior management team and other key employees. We rely on our leadership team in the areas of sales and operations, information technology and security, marketing, and general and administrative functions. From time to time, there may be changes in our executive management team resulting from the hiring or departure of executives, which could disrupt our business. Our executive officers and other key personnel are not subject to any restrictions that would require them to continue to work for us for any specified period and, therefore, they could terminate their employment with us at any time. The loss of one or more of the members of our senior management team, or other key employees, could harm our business. Changes in our executive management team may also cause disruptions in, and harm to, our business. See “—We must attract and retain highly qualified personnel in order to execute our growth plan.”

TABLE OF CONTENTS

We must attract and retain highly qualified personnel in order to execute our growth plan.

Competition for highly qualified personnel is intense. We have, from time to time, experienced, and we expect to continue to experience, difficulty in hiring and retaining employees with appropriate qualifications. Many of the companies with which we compete for experienced personnel have greater resources than we have. If we hire employees from competitors or other companies, their former employers may attempt to assert that these employees or we have breached certain legal obligations, resulting in a diversion of our time and resources. If we fail to attract new personnel or fail to retain and motivate our current personnel, our business and future growth prospects could be harmed.

Our products and technology could have undetected defects, errors, or bugs in hardware or software which could reduce market adoption, damage our reputation with current or prospective customers and/or expose us to product liability and other claims that could materially and adversely affect our business.

We may be subject to claims that our hardware and software-enabled services have malfunctioned and persons were injured or purported to be injured. Any insurance that we carry may not be sufficient or it may not apply to all situations. Similarly, to the extent that such malfunctions are related to components obtained from third-party vendors, such vendors may not assume responsibility for such malfunctions. In addition, our customers could be subjected to claims as a result of such incidents and may bring legal claims against us to attempt to hold us liable. Any of these events could adversely affect our brand, relationships with customers, operating results, or financial condition. For example, on September 4, 2021, a 300 MW energy storage facility owned by one of our customers experienced an overheating event. Fluence served as the energy storage technology provider and installed the facility, which was completed earlier in fiscal year 2021. No injuries were reported from the incident. The facility has been taken offline as teams from Fluence, our customer, and the battery manufacturer investigate the incident. We are currently not able to estimate the impact, if any, that this incident may have on our reputation or financial results, or on market adoption of our products.

Furthermore, our products and technology platform are complex and developed by many employees with various components of hardware and software sourced from third-parties. Our products and software have contained design and manufacturing-related defects and errors and may in the future contain undetected defects or errors. Our installation and construction work have contained and in the future may contain workmanship errors. We are continuing to evolve the features and functionality of our products and technology platform through updates and enhancements, and as we do, we may introduce additional defects or errors that may not be detected until after deployment to customers through our hardware. In addition, if our hardware and software-enabled services, including any updates or patches, are not implemented or used correctly or as intended, inadequate performance, data breaches, and disruptions in service may result.

In particular, the Fluence Bidding Application delivers artificial intelligence-enabled bidding software for utility-scale storage and renewable generation assets, enabling customers to optimize asset trading in wholesale electricity markets. While we generally are not regulated as a utility or a broker-dealer, customers of the Fluence Bidding Application are regulated utilities. We could experience scrutiny from regulators for providing the Fluence Bidding Application to our customers.

Any defects or errors in product or services offerings, or the perception of such defects or errors, or other performance problems could result in any of the following, each of which could adversely affect our business, financial condition, and results of operations:

•

expenditure of significant financial and product development resources, including recalls, in efforts to analyze, correct, eliminate, or work around errors or defects;

•

loss of existing or potential customers or partners;

•

interruptions or delays in sales;

•

delayed or lost revenue;

•

delay or failure to attain market acceptance;

•

delay in the development or release of new functionality or improvements;

TABLE OF CONTENTS

•

negative publicity and reputational harm;

•

sales credits or refunds;

•

security vulnerabilities, data breaches, and exposure of confidential or proprietary information;

•

diversion of development and customer service resources;

•

breach of warranty claims;

•

legal claims under applicable laws, rules, and regulations; and

•

the expense and risk of litigation.

Although we have contractual protections, such as warranty disclaimers and limitation of liability provisions, in many of our agreements with customers, resellers, and other business partners, such protections may not be uniformly implemented in all contracts and, where implemented, may not fully or effectively protect from claims by customers, resellers, business partners or other third parties. Any insurance coverage or indemnification obligations of suppliers may not adequately cover all such claims, or cover only a portion of such claims. A successful product liability, warranty, or other similar claim could have an adverse effect on our business, financial condition, and operating results. In addition, even claims that ultimately are unsuccessful could result in expenditure of funds in litigation, divert management’s time and other resources, and cause reputational harm.

Compromises, interruptions, or shutdowns of our systems, including those managed by third parties, whether intentional or inadvertent, could lead to delays in our business operations and, if significant or extreme, affect our results of operations.

From time to time, our systems require modifications and updates, including by adding new hardware, software, and applications; maintaining, updating, or replacing legacy programs; and integrating new service providers and adding enhanced or new functionality. Although we are actively selecting systems and vendors and implementing procedures to enable us to maintain the integrity of our systems when we modify them, there are inherent risks associated with modifying or replacing systems, and with new or changed relationships, including accurately capturing and maintaining data, realizing the expected benefit of the change, and managing the potential disruption of the operation of the systems as the changes are implemented. Potential issues associated with implementation of these technology initiatives could reduce the efficiency of our operations in the short term. The efficient operation and successful growth of our business depends upon our information technology systems. The failure of our information technology systems and the third-party systems we rely on to perform as designed, or our failure to implement and operate them effectively, could disrupt our business or subject us to liability and thereby have a material adverse effect on our business, financial condition, results of operations, and prospects.

Our current and planned foreign operations could subject us to additional business, financial, regulatory, and competitive risks.

We sell our products in a number of different countries, including the United States, the United Kingdom, multiple EU countries, Australia, and the Philippines. We have in the past, and may in the future, evaluate opportunities to expand into new geographic markets and introduce new product offerings and services that are a natural extension of our existing business. We also may from time to time engage in acquisitions of businesses or product lines with the potential to strengthen our market position, enable us to enter attractive markets, expand our technological capabilities, or provide synergy opportunities.

Our success operating in these new geographic or product markets, or in operating any acquired business, will depend on a number of factors, including our ability to develop solutions to address the requirements of the battery energy storage industry, our timely qualification and certification of new products, our ability to manage increased manufacturing capacity and production, and our ability to identify and integrate any acquired businesses.

Further, any additional markets that we may enter could have different characteristics from the markets in which we currently sell products, and our success will depend on our ability to adapt properly to these

TABLE OF CONTENTS

differences. These differences may include regulatory requirements, including tax laws, trade laws, labor regulations, tariffs, export quotas, customs duties, or other trade restrictions, limited or unfavorable intellectual property protection, international, political, or economic conditions, restrictions on the repatriation of earnings, longer sales cycles, warranty expectations, product return policies, and cost, performance, and compatibility requirements. In addition, expanding into new geographic markets will increase our exposure to presently existing and new risks, such as fluctuations in the value of foreign currencies and difficulties and increased expenses in complying with United States and foreign laws, regulations, and trade standards, including the Foreign Corrupt Practices Act of 1977, as amended.

Tax laws and regulations in various jurisdictions where we currently operate or may operate in the future also could result in additional tax liabilities for us or otherwise adversely affect us. See the discussion under “—Changes in tax laws or regulations that are applied adversely to us or our customers could materially adversely affect our business, financial condition, results of operations and prospects.” below.

Failure to develop and introduce new products successfully into the market, to successfully integrate acquired businesses or to otherwise manage the risks and challenges associated with our potential expansion into new product and geographic markets, could adversely affect our revenues and our ability to sustain profitability.

Amounts included in our pipeline and contracted backlog may not result in actual revenue or translate into profits.

As of September 30, 2021, our pipeline, which represents potential contracts where we either have been selected by the customer or have provided the customer a quote or bid, but for which the contracts have not been signed, was 14.2 GW compared to 11.3 GW as of September 30, 2020. As of September 30, 2021, we estimated that we had between approximately $1,344 million and $1,393 million of contracted backlog related to energy storage products. We define “contracted backlog” as signed purchase orders or contractual minimum purchase commitments with take-or pay provisions. For our energy storage product contracts, contracted backlog includes signed customer orders or contracts under execution prior to when substantial completion is achieved. For service contracts, contracted backlog includes signed service agreement associated with our storage product projects that have not been completed. For digital applications contracts, contracted backlog includes signed agreements where the associated subscription has not started.

Our pipeline and contracted backlog are based on numerous assumptions and limitations, are calculated using our internal data that have not been independently verified by third parties and may not provide an accurate indication of our future or expected results. Pipeline and contracted backlog are internal management metrics that we construct from market information reported by our global sales force. We monitor and track our pipeline and contracted backlog, but they are not maintained or audited in accordance with U.S. GAAP. Although the amount of contracted backlog includes signed purchase orders or other contractual commitments and the amount of pipeline includes potential future orders, we cannot guarantee that our pipeline or contracted backlog will result in actual revenue in the originally anticipated period or at all. Our customers operate in a relatively new industry and have based their commitments to us on assumptions about future energy prices, demand levels, regulatory obligations and incentives, among other factors. Further, certain of those customers may need to obtain financing to fulfill their commitments to us. If the market does not grow as expected, the regulatory environment changes, or customers fail to obtain necessary financial backing, customers may fail to satisfy their minimum purchase commitments to us and we would fail to realize our contracted backlog. In that event, our revenue and profitability could be adversely affected. Our pipeline or contracted backlog may not generate margins equal to our historical operating results. We have only recently begun to track our pipeline and contracted backlog on a consistent basis, and as a result, we do not have significant experience in determining the level of realization that we will achieve on these contracts. Our customers may experience project delays or cancel orders as a result of external market factors and economic or other factors beyond our control. If our pipeline or backlog fails to result in revenue at all or in a timely manner, we could experience a reduction in revenue, profitability, and liquidity. See the sections titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Operating Metrics—Pipeline” for additional information regarding our pipeline and “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors And Trends” for additional information regarding our pipeline and contracted backlog.

TABLE OF CONTENTS

Our hardware and software-enabled services involve a lengthy sales and installation cycle, and if we fail to close sales on a regular and timely basis it could adversely affect our business, financial condition, and results of operations.

Our sales cycle is typically three (3) to twelve (12) months for our hardware and software-enabled services but can vary considerably. In order to make a sale, we must typically provide a significant level of education to prospective customers regarding the use and benefits of our hardware and software-enabled services.

The period between initial discussions with a potential customer and the sale of even a single energy storage product typically depends on a number of factors, including the potential customer’s budget and decision as to the type of financing it chooses to use, as well as the arrangement of such financing. Prospective customers often undertake a significant evaluation process, which may further extend the sales cycle. This lengthy sales and installation cycle is subject to a number of significant risks over which we have little or no control. Because of both the long sales and installation cycles, we may expend significant resources without having certainty of generating a sale.

These lengthy sales and installation cycles increase the risk that our customers may fail to satisfy their payment obligations, cancel orders before the completion of the transaction, or delay the planned date for installation. Cancellation rates may be impacted by factors outside of our control including an inability to install an energy storage product at the customer’s chosen location because of permitting or other regulatory issues, unanticipated changes in the cost or availability of alternative sources of electricity available to the customer, or other reasons unique to each customer. Our operating expenses are based on anticipated sales levels, and many of our expenses are fixed. If we are unsuccessful in closing sales after expending significant resources or if we experience delays or cancellations, our business, financial condition, and results of operations could be adversely affected.

Additionally, we have long-term, multi-year service contracts with some of our customers. If those contracts are terminated or if we are unable to continue to fulfill the obligations under such contracts, our business, financial condition, and results of operations could be adversely affected.

Any failure to offer high-quality technical support services may adversely affect our relationships with our customers and adversely affect our financial results.

Our customers depend on our support organization to resolve any technical issues relating to our hardware and software-enabled services. In addition, we have, in some instances, provided performance guarantees for our products and services to our customers. Any failure meet such guarantees or to maintain high-quality and highly-responsive technical support, or a market perception that we do not maintain high-quality and highly-responsive support, could adversely affect our reputation, our ability to sell our products to existing and prospective customers, and our business, financial condition, and results of operations.

We offer technical support services with our hardware and software-enabled services and may be unable to respond quickly enough to accommodate short-term increases in demand for support services, particularly as we increase the size of our customer base. We also may be unable to modify the format of our support services to compete with changes in support services provided by competitors. It is difficult to predict demand for technical support services and if demand increases significantly, we may be unable to provide satisfactory support services to our customers. Additionally, increased demand for these services, without corresponding revenue, could increase costs and adversely affect our business, financial condition, and results of operations.

We may experience difficulties in establishing mass manufacturing capacity and estimating potential cost savings and efficiencies from anticipated improvements to our manufacturing capabilities.

While our manufacturing output achieved to date is already at commercial scale, it is a fraction of what we expect will be necessary to fully meet the demand we see in the market for our products. The manufacturing process for our expected full commercial scale is still being refined and improved. There are risks associated with scaling up manufacturing to larger commercial volumes including, among others, technical or other

TABLE OF CONTENTS

problems with process scale-up, process reproducibility, stability issues, quality consistency, timely availability of raw materials, cost overruns, and adequate definitions or qualifications for safety, reliability, and quality. In addition, in connection with our limited operating history and our significant growth, we have in the past experienced and may in the future experience incurrence of project costs without proper documentation or adhering to our policies and procedures. There is no assurance that our manufacturers will be successful in establishing a larger-scale commercial manufacturing process that achieves our objectives for manufacturing capacity and cost per battery, in a timely manner or at all. If we are unable to produce sufficient quantities of product on a timely basis and in a cost-effective manner, the Company’s commercialization efforts would be impaired which could materially affect our business, financial condition, results of operations, and growth prospects.

If our estimates of useful life for our energy storage products and related hardware and software-enabled services are inaccurate or if our component OEM suppliers do not meet service and performance warranties and guarantees, our business and financial results could be adversely affected.

We sell hardware and software-enabled services to our customers. Our software-enabled services are essential to the operation of these hardware products. Our pricing of services contracts is based upon the value we expect to deliver to our customers, including considerations such as the useful life of the energy storage product and prevailing electricity prices. We also provide warranties and guarantees covering the efficiency and performance of certain of our products and digital applications, in some cases up to 25 years in length. We do not have a long history with a large number of field deployments, and our estimates may prove to be incorrect. Failure to meet these performance warranties and guarantee levels may require us to refund our service contract payments to the customer or require us to make cash payments to the customer based on actual performance, as compared to expected performance.

As part of growing our business, we have made and expect to continue to make acquisitions. If we fail to successfully select, execute, or integrate our acquisitions, then our business and operating results could be harmed and our stock price could decline.

We will continuously evaluate potential acquisitions to add new product lines and technologies, gain new sales channels, or enter into new sales territories. For example, in 2020, we acquired AMS’ software and digital intelligence platform, which became the Fluence Bidding Application. Acquisitions involve numerous risks and challenges, including but not limited to the following:

•

integrating the companies, assets, systems, products, sales channels, and personnel that we acquire;

•

higher than anticipated acquisition and integration costs and expenses;

•

reliance on third parties to provide transition services for a period of time after closing to ensure an orderly transition of the business;

•

growing or maintaining revenues to justify the purchase price and the increased expenses associated with acquisitions;

•

entering into territories or markets with which we have limited or no prior experience;

•

establishing or maintaining business relationships with customers, vendors, and suppliers who may be new to us;

•

overcoming the employee, customer, vendor, and supplier turnover that may occur as a result of the acquisition;

•

disruption of, and demands on, our ongoing business as a result of integration activities including diversion of management’s time and attention from running the day to day operations of our business;

•

inability to implement uniform standards, disclosure controls and procedures, internal controls over financial reporting, and other procedures and policies in a timely manner;

•

inability to realize the anticipated benefits of or successfully integrate with our existing business the businesses, products, technologies or personnel that we acquire; and

•

potential post-closing disputes.

TABLE OF CONTENTS

As part of undertaking an acquisition, we may also significantly revise our capital structure or operational budget, such as issuing common stock that would dilute the ownership percentage of our stockholders, assuming liabilities or debt, utilizing a substantial portion of our cash resources to pay for the acquisition, or significantly increasing operating expenses. In addition, our effective tax rate in any particular quarter may also be impacted by acquisitions. Following the closing of an acquisition, we may also have disputes with the seller regarding contractual requirements and covenants, purchase price adjustments, contingent payments, or for indemnifiable losses. Any such disputes may be time consuming and distract management from other aspects of our business. In addition, if we increase the pace or size of acquisitions, we will have to expend significant management time and effort into the transactions and integrations, and we may not have the proper human resources bandwidth to ensure successful integrations and accordingly, our business could be harmed or the benefits of our acquisitions may not be realized.

As part of the terms of an acquisition, we may commit to pay additional contingent consideration if certain revenue or other performance milestones are met. We are required to evaluate the fair value of such commitments at each reporting date and adjust the amount recorded if there are changes to the fair value.

We cannot ensure that we will be successful in identifying, selecting, executing, and integrating acquisitions. Failure to manage and successfully integrate acquisitions could materially harm our business and operating results. In addition, if stock market analysts or our stockholders do not support or believe in the value of the acquisitions that we choose to undertake, our stock price may decline.

Our customer relationships, business, financial results and reputation may be adversely impacted due to events and incidents relating to storage, delivery, installation, operation and shutdowns of our energy storage products, including events and incidents outside of our control. We are subject to various risks as a result of the size, weight, nature and sophisticated nature of our energy storage products, including exposure to production, delivery, supply chain, inventory, installation and maintenance issues. Such issues may, and from time to time have, result in financial losses, including losses resulting from our failure to deliver or install our energy storage products on a contractually agreed timeframe, or losses resulting from agreed warranty or indemnity terms. Furthermore, issues and incidents involving our customers or their facilities at which our energy storage products are located, whether or not attributable to our energy storage products, may have an adverse effect on our reputation and customer relationships. Any of these developments could have a material adverse effect on our business, financial condition, and results of operations. For example, on September 4, 2021, a 300 MW energy storage facility owned by one of our customers experienced an overheating event. Fluence served as the energy storage technology provider and installed the facility, which was completed earlier in fiscal year 2021. No injuries were reported from the incident. The facility has been taken offline as teams from Fluence, our customer, and the battery manufacturer investigate the incident. We are currently not able to estimate the financial impact, if any, that this incident may have on our financial results.

We may acquire companies for both strategic and financial reasons but may not realize a return on our investments.

We have acquired, and plan to continue to seek to acquire, other companies to further our strategic objectives and support our key business initiatives. These investments may include acquiring equity or debt instruments of public or private companies which may be non-marketable at the time of our initial investment. We do not restrict the types of companies which we might seek to acquire. These companies may range from early-stage companies that are often still defining their strategic direction to more mature companies with established revenue streams and business models. We must also analyze tax, accounting, and legal issues when making these acquisitions. If we do not structure these acquisitions properly, we may be subject to certain unfavorable accounting or tax impact.

We face risks related to actual or threatened health epidemics, such as the COVID-19 pandemic, and other outbreaks, which could significantly disrupt our suppliers’ manufacturing and our operations.

Our business could be adversely impacted by the effects of a widespread outbreak of contagious disease, including the recent outbreak of respiratory illness caused by the COVID-19 pandemic. Any

TABLE OF CONTENTS

widespread outbreak of contagious diseases, and other adverse public health developments, could cause disruption to, among other things, our ground operations at project sites, our manufacturing facilities and our suppliers and vendors located in the United States, Asia and elsewhere and have a material and adverse effect on our business operations. Our ground operations at project sites, our manufacturing facilities and our suppliers and vendors could be disrupted by worker absenteeism, quarantines, shortage of the COVID-19 pandemic test kits and personal protection equipment for employees, office and factory closures, disruptions to ports and other shipping infrastructure, or other travel or health-related restrictions. If our ground operations at project sites, our manufacturing facilities and our suppliers or vendors are so affected, our supply chain, manufacturing and product shipments will be delayed, which could adversely affect our business, operations and customer relationships. For example, our suppliers and vendors in Asia have been affected by business closures and disruptions to ports and other shipping infrastructure. In addition, the macroeconomic effects of the COVID-19 pandemic in the United States and other markets has resulted in a widespread health crisis that has adversely affected the economies and financial markets of many countries, resulting in an economic downturn that could affect demand for our products and impact our operating results.

Given the ongoing and dynamic nature of the circumstances, it is difficult to predict the full impact of the COVID-19 pandemic on our business. The extent of such impact will depend on future developments, which are highly uncertain, including when the COVID-19 pandemic can be controlled and abated. Further, while jurisdictions in which we operate have gradually allowed the reopening of businesses and other organizations and removed the sheltering restrictions, it is premature to assess whether doing so will result in a meaningful increase in economic activity and the impact of such actions on further the COVID-19 pandemic cases.

We are monitoring the recent global health emergency driven by the potential impact of the COVID-19 pandemic, along with global supply and demand dynamics. The extent to which these events may impact our business will depend on future developments, which are highly uncertain and cannot be predicted at this time.

We have encountered and could encounter in the future project delays and resulting liquidated damages claims from customers due to impacts on suppliers, customers, or others. The duration and intensity of these impacts and resulting disruption to our operations is uncertain and continues to evolve as of the date of this filing. Accordingly, management will continue to monitor the impact of the global situation on its financial condition, liquidity, operations, suppliers, industry, and workforce.

To the extent the COVID-19 pandemic adversely affects our financial condition, operating results and cash flows, it may also have the effect of heightening many of the other risks described in this “Risk Factors” section, such as those relating to our high level of indebtedness, our need to generate sufficient cash flows to service our indebtedness and our ability to comply with the covenants contained in the agreements that govern our indebtedness.

Risks Related to Our Industry

If renewable energy technologies are not suitable for widespread adoption or sufficient demand for our hardware and software-enabled services does not develop or takes longer to develop than we anticipate, our sales may decline, and we may be unable to achieve or sustain profitability.

The market for renewable, distributed energy generation is emerging and rapidly evolving, and its future success is uncertain. If renewable energy generation proves unsuitable for widespread commercial deployment or if demand for our renewable energy hardware and software-enabled services fails to develop sufficiently, we would be unable to achieve sales and market share.

Many factors may influence the widespread adoption of renewable energy generation and demand for our hardware and software-enabled services, including, but not limited to, the cost-effectiveness of renewable energy technologies as compared with conventional and competitive technologies, the performance and reliability of renewable energy products as compared with conventional and non-renewable products, fluctuations in economic and market conditions that impact the viability of conventional and competitive alternative energy sources, increases or decreases in the prices of oil, coal and natural gas, continued

TABLE OF CONTENTS

deregulation of the electric power industry and broader energy industry, and the availability or effectiveness of government subsidies and incentives. You should consider our prospects in light of the risks and uncertainties emerging companies encounter when introducing new products and services into a nascent industry.

The growth and profitability of our business is dependent upon the continued decline in the cost of battery storage. Over the last decade the cost of battery storage products, particularly lithium-ion based battery storage products, have declined significantly. This lower cost has been driven by advances in battery technology, maturation of the battery supply chain, the scale of battery production by the leading manufacturers and other factors. The growth of our hardware sales and related software-enabled services is dependent upon the continued decrease in the price and efficiency of battery storage products of our component OEM suppliers. If for any reason our component OEM suppliers are unable to continue to reduce the price of their battery storage products, our business and financial condition will be negatively impacted.

If the estimates and assumptions we use to determine the size of our total addressable market are inaccurate, our future growth rate may be affected, and the potential growth of our business may be limited.

Market estimates and growth forecasts are subject to significant uncertainty and are based on assumptions and estimates that may prove to be inaccurate. Even if the market in which we compete meets our size estimates and forecasted growth, our business could fail to grow at similar rates, if at all. The assumptions relating to our market opportunity include, but are not limited to, the following: (i) according to BloombergNEF, global energy storage capacity grew 63% per annum between 2015 and 2020 and is expected to grow at a further 41% annual growth rate through 2025; (ii) declines in lithium-ion battery costs and in the cost of renewable generation; (iii) growing demand for renewable energy; and (iv) increased complexity of the electrical grid. Our market opportunity is also based on the assumption that our existing and future offerings will be more attractive to our customers and potential customers than competing products and services. If these assumptions prove inaccurate, our business, financial condition, and results of operations could be adversely affected. For more information regarding our estimates of market opportunity and the forecasts of market growth included herein, see the section entitled “Business.”

The economic benefit of our energy storage products to our customers depends on the cost of electricity available from alternative sources, including local electric utility companies, which cost structure is subject to change.

The economic benefit of our energy storage products to our customers includes, among other things, the benefit of reducing such customer’s payments to the local electric utility company. The rates at which electricity is available from a customer’s local electric utility company is subject to change and any changes in such rates may affect the relative benefits of our energy storage products. Further, the local electric utility may impose “departing load,” “standby” or other charges on our customers in connection with their acquisition of our energy storage products, the amounts of which are outside of our control and which may have a material impact on the economic benefit of our energy storage products to our customers. Changes in the rates offered by local electric utilities and/or in the applicability or amounts of charges and other fees imposed by such utilities on customers acquiring our energy storage products could adversely affect the demand for our energy storage products.

Existing electric utility industry policies and regulations, and any subsequent changes, may present technical, regulatory, and economic barriers to the purchase and use of energy storage products that may significantly reduce demand for our products or harm our ability to compete.

Federal, state, local, and foreign government regulations and policies concerning the broader electric utility industry, as well as internal policies and regulations promulgated by electric utilities and organized electric markets with respect to fees, practices, and rate design, heavily influence the market for electricity generation products and services. These regulations and policies often affect electricity pricing and the interconnection of generation facilities, and can be subject to frequent modifications by governments, regulatory bodies, utilities, and market operators. For example, changes in fee structures, electricity pricing structures, and system permitting, interconnection, and operating requirements can deter purchases of

TABLE OF CONTENTS

renewable energy products by reducing anticipated revenues or increasing costs or regulatory burdens for would-be system purchasers. The resulting reductions in demand for energy products could harm our business, prospects, financial condition, and results of operations.

A significant recent development in renewable-energy pricing policies in the U.S. occurred on July 16, 2020, when the Federal Energy Regulatory Commission (“FERC”) issued a final rule amending regulations that implement the Public Utility Regulatory Policies Act (“PURPA”). Among other requirements, PURPA mandates that electric utilities buy the output of certain renewable generators below established capacity thresholds. PURPA also requires that such sales occur at a utility’s “avoided cost” rate. FERC’s PURPA reforms include modifications (1) to how regulators and electric utilities may establish avoided cost rates for new contracts; (2) that reduce from 20 MW to 5 MW the capacity threshold above which a renewable-energy qualifying facility is rebuttably presumed to have nondiscriminatory market access, thereby removing the requirement for utilities to purchase its output; (3) that require regulators to establish criteria for determining when an electric utility incurs a legally enforceable obligation to purchase from a PURPA facility; and (4) that reduce barriers for third parties to challenge PURPA eligibility. The net effect of these changes is uncertain, as FERC’s final rules do not become effective until 120 days after publication in the Federal Register, and some changes will not become fully effective until states and other jurisdictions implement the new authorities provided by FERC. In general, however, FERC’s PURPA reforms have the potential to reduce prices for the output from certain new renewable generation projects while also narrowing the scope of PURPA eligibility for new projects. These effects could reduce demand for PURPA-eligible battery energy storage products and could harm our business, prospects, financial condition, and results of operations.

Changes in other current laws or regulations applicable to us or the imposition of new laws, regulations, or policies in the U.S., Europe, or other jurisdictions in which we do business could have a material adverse effect on our business, financial condition, and results of operations. Any changes to government, utility, or electric market regulations or policies that favor electric utilities or other market participants could reduce the competitiveness of battery energy storage products and cause a significant reduction in demand for our products and services and adversely impact our growth. In addition, changes in our products or changes in export and import laws and implementing regulations may create delays in the introduction of new products in international markets, prevent our customers from deploying our products internationally or, in some cases, prevent the export or import of our products to certain countries altogether. Any such event could have a material adverse effect on our business, financial condition, and results of operations.

An increase in interest rates or a reduction in the availability of tax equity or project debt capital in the global financial markets could make it difficult for end customers to finance the cost of a renewable energy system and could reduce the demand for our products.

Many end users depend on financing to fund the initial capital expenditure required to purchase our products and services. As a result, an increase in interest rates or a reduction in the supply of project debt or tax equity financing could reduce the number of customer projects that receive financing or otherwise make it difficult for our customers or their customers to secure the financing necessary to construct a renewable energy system on favorable terms, or at all, and thus lower demand for our products, which could limit our growth or reduce our net sales. In addition, we believe that a significant percentage of end-users construct renewable energy systems as an investment, funding a significant portion of the initial capital expenditure with financing from third parties. An increase in interest rates could lower an investor’s return on investment, increase equity requirements, or make alternative investments more attractive relative to our products and services and, in each case, could cause these end users to seek alternative investments.

Changes in tax laws or regulations that are applied adversely to us or our customers could materially adversely affect our business, financial condition, results of operations, and prospects.

Changes in corporate tax rates, tax incentives for renewable energy projects, the realization of net deferred tax assets relating to our U.S. operations, the taxation of foreign earnings, and the deductibility of expenses under future tax reform legislation could have a material impact on the value of our deferred tax assets, could result in significant one-time charges in the current or future taxable years, and could increase our future U.S. tax expense, which could have a material adverse effect on our business, financial condition, results of operations, and prospects.

TABLE OF CONTENTS

Governmental agencies in the jurisdictions in which we and our affiliates do business, as well as the Organization for Economic Cooperation and Development (the “OECD”), have recently focused on issues related to the taxation of multinational business, including issues relating to “base erosion and profit shifting,” where profits are reported as earned for tax purposes in relatively low-tax jurisdictions or payments are made between affiliates in jurisdictions with different tax rates. The OECD has released several components of its comprehensive plan to create an agreed set of international rules for addressing base erosion and profit shifting, and governmental authorities from various jurisdictions (including the United States) continue to discuss potential legislation and other reforms, including proposals for global minimum tax rates.

As we operate in numerous jurisdictions, the application of tax laws can be subject to diverging and sometimes conflicting interpretations by tax authorities of these jurisdictions. It is not uncommon for taxing authorities in different countries to have conflicting views, for instance with respect to whether a permanent establishment exists in a particular jurisdiction, the manner in which an arm’s length standard is applied for transfer pricing purposes, or with respect to the valuations of intellectual property. For example, if a taxing authority in one country where we operate were to reallocate income from another country where we operate, and if the taxing authority in the second country did not agree with the reallocation asserted by the first country, then we could be subject to tax on the same income in both countries, resulting in double taxation. If taxing authorities were to allocate income to a higher tax jurisdiction, subject our income to double taxation or assess interest and penalties, our tax liabilities could increase, which could adversely affect our business, financial condition, and results of operations.

Due to the potential for changes to tax laws and regulations or changes to the interpretation thereof (including regulations and interpretations pertaining to recent and proposed potential tax reforms in the United States), the ambiguity of tax laws and regulations, the subjectivity of factual interpretations, the complexity of our intercompany arrangements, uncertainties regarding the geographic mix of earnings in any particular period, and other factors, our estimates of effective tax rate and income tax assets and liabilities may be incorrect and our financial statements could be adversely affected, and the resulting impacts may vary substantially from period to period.

In particular, in the United States, there have been multiple significant changes recently proposed (including by the Biden administration and by members of Congress) to the taxation of business entities, including, among other things, an increase in the U.S. federal corporate income tax rate, a transition to graduated rates, an increase in the tax rate applicable to global intangible low-taxed income and elimination of certain exemptions, and various other changes to the U.S. international tax regime. These and other proposals are currently being discussed, but the likelihood of these changes being enacted or implemented is not yet clear. We are currently unable to predict whether such changes will occur and, if so, when they would be effective or the ultimate impact on us or our business. To the extent that such changes have a negative impact on us or our business, these changes may materially and adversely impact our business, financial condition, and results of operations.

In addition, the amounts of taxes we pay are subject to current or future audits by taxing authorities in the United States and all other jurisdictions in which we operate. If audits result in additional payments or assessments different from our reserves, our future results may include unfavorable adjustments to our tax liabilities, and our financial statements could be adversely affected.

We may incur obligations, liabilities, or costs under environmental, health, and safety laws, which could have an adverse impact on our business, financial condition, and results of operations.

We are required to comply with national, state, local, and foreign laws and regulations regarding the protection of the environment, health, and safety. We may incur expenses, or be subject to liability, related to the transportation, storage, or disposal of lithium-ion batteries. Adoption of more stringent laws and regulations in the future could require us to incur substantial costs to come into compliance with these laws and regulations. In addition, violations of, or liabilities under, these laws and regulations may result in restrictions being imposed on our operating activities or in our being subject to adverse publicity, substantial fines, penalties, criminal proceedings, third-party property damage or personal injury claims, cleanup costs, or other costs. Liability under these laws and regulations can be imposed on a joint and several basis and without regard to fault or the legality of the activities giving rise to the claim. In addition, future developments such as more aggressive enforcement policies or the discovery of presently unknown

TABLE OF CONTENTS

environmental conditions may require expenditures that could have an adverse effect on our business, financial condition, and results of operations.

The reduction, elimination, or expiration of government incentives for, or regulations mandating the use of, renewable energy could reduce demand for energy storage products and harm our business.

Federal, state, local, and foreign government bodies provide incentives to owners, end users, distributors, system integrators and manufacturers of renewable energy products to promote renewable electricity in the form of rebates, tax credits and other financial incentives.

The range and duration of these incentives varies widely by jurisdiction. Our customers typically use our products for grid-connected applications wherein power is sold under a power purchase agreement or into an organized electric market. The reduction, elimination, or expiration of government incentives for grid-connected electricity may negatively affect the competitiveness of our offerings relative to conventional renewable sources of electricity and could harm or halt the growth of our industry and our business. These subsidies and incentives may expire on a particular date, end when the allocated funding is exhausted or be reduced or terminated as renewable energy adoption rates increase or as a result of legal challenges, the adoption of new statutes or regulations, or the passage of time. These reductions or terminations may occur without warning.

Revenue from any projects we support may be adversely affected if there is a decline in public acceptance or support of renewable energy, or regulatory agencies, local communities, or other third parties delay, prevent, or increase the cost of constructing and operating customer projects.

Certain persons, associations and groups could oppose renewable energy projects in general or our customers’ projects specifically, citing, for example, misuse of water resources, landscape degradation, land use, food scarcity or price increase, and harm to the environment. Moreover, regulation may restrict the development of renewable energy plants in certain areas. In order to develop a renewable energy project, our customers are typically required to obtain, among other things, environmental impact permits or other authorizations and building permits, which in turn require environmental impact studies to be undertaken and public hearings and comment periods to be held during which any person, association, or group may oppose a project. Any such opposition may be taken into account by government officials responsible for granting the relevant permits, which could result in the permits being delayed or not being granted or being granted solely on the condition that our customers carry out certain corrective measures to the proposed project.

Severe weather events, including the effects of climate change, are inherently unpredictable and may have a material adverse effect on our financial results and financial condition.

Our business, including our customers and suppliers, may be exposed to severe weather events and natural disasters, such as tornadoes, tsunamis, tropical storms (including hurricanes), earthquakes, windstorms, hailstorms, severe thunderstorms, wildfires, and other fires, which could cause operating results to vary significantly from one period to the next. We may incur losses in our business in excess of: (1) those experienced in prior years, (2) the average expected level used in pricing, or (3) current insurance coverage limits. The incidence and severity of severe weather conditions and other natural disasters are inherently unpredictable. Climate change may affect the occurrence of certain natural events, such as an increase in the frequency or severity of wind and thunderstorm events, and tornado or hailstorm events due to increased convection in the atmosphere; more frequent wildfires and subsequent landslides in certain geographies; higher incidence of deluge flooding; and the potential for an increase in severity of the hurricane events due to higher sea surface temperatures. Additionally, climate change may adversely impact the demand, price, and availability of insurance. Due to significant variability associated with future changing climate conditions, we are unable to predict the impact climate change will have on our business.

Risks Related to Our Financial Condition and Liquidity

Our order intake and cash flows have been highly seasonal, which could make our future performance difficult to predict and could cause our results of operations for a particular period to fluctuate from quarter to quarter or fall below expectations, resulting in a decline in the price of our Class A common stock.

Our quarterly results of operations are difficult to predict and may fluctuate significantly in the future. We experience seasonality and typically see increased order intake in our third and fourth fiscal quarters,

TABLE OF CONTENTS

driven by demand in the Northern Hemisphere to install energy storage products before the summer of the following year. Our services and digital application offerings do not experience the same seasonality given their recurring nature. Combined third and fourth fiscal quarter order intake for energy storage products in fiscal year 2020 and fiscal year 2019 accounted for 80% or more of our total intake each year. As a result, revenue recognition is significantly stronger in our third and fourth fiscal quarters. Cash flows historically have been negative in our first and second fiscal quarters, neutral to positive in our third fiscal quarter, and positive in our fourth fiscal quarter. See “Recent Developments — Preliminary Fourth Quarter Results.”

We have a history of net losses, we anticipate increasing expenses in the future, and we may not be able to achieve or maintain profitability.

We have incurred net losses on an annual basis since our inception. We incurred net losses of $46.7 million and $47.0 million for the years ended September 30, 2020 and 2019, respectively, and net losses of $74.6 million and $42.7 million for the nine months ended June 30, 2021 and 2020, respectively. We expect our aggregate costs will increase substantially in the foreseeable future and our losses will continue as we expect to invest heavily in increasing our customer base, expanding our operations, hiring additional employees, and operating as a public company. These efforts may prove more expensive than we currently anticipate, and we may not succeed in increasing our revenue sufficiently to offset these higher expenses. To date, we have financed our operations with equity contributions from AES Grid Stability, Siemens Industry, and QFH, cash and cash equivalents, negative working capital, and short-term borrowings. Our net cash flow from operations was negative for the year ended September 30, 2020 and the nine months ended June 30, 2021. We may not generate positive cash flow from operations or profitability in any given period, and our limited operating history may make it difficult for you to evaluate our current business and our future prospects.

We have encountered and will continue to encounter risks and difficulties frequently experienced by growing companies in rapidly changing industries, including increasing expenses as we continue to grow our business. We expect our operating expenses to increase significantly over the next several years as we continue to hire additional personnel, expand our operations and infrastructure, and continue to expand to reach more customers. In addition to the expected costs to grow our business, we also expect to incur additional legal, accounting, and other expenses as a newly public company. These investments may be more costly than we expect, and if we do not achieve the benefits anticipated from these investments, or if the realization of these benefits is delayed, they may not result in increased revenue or growth in our business. If our growth rate were to decline significantly or become negative, it could adversely affect our financial condition and results of operations. If we are not able to achieve or maintain positive cash flow in the long term, we may require additional financing, which may not be available on favorable terms or at all and/or which would be dilutive to our stockholders. If we are unable to successfully address these risks and challenges as we encounter them, our business, results of operations and financial condition would be adversely affected. Our failure to achieve or maintain profitability could negatively impact the value of our common stock.

The Revolver we will enter into in connection with this offering imposes certain restrictions that may affect our ability to operate our business and make payments on our indebtedness.

In connection with this offering, we plan to enter into the Revolver, which will contain covenants that, among other things, will restrict our ability to incur additional indebtedness; incur liens; sell, transfer, or dispose of property and assets; invest; make dividends or distributions or other restricted payments and engage in affiliate transactions. In addition, we will be required to maintain (i) minimum liquidity and gross revenue requirements, in each case, until consolidated EBITDA reaches a certain specified threshold and we make an election, and (ii) thereafter, a maximum total leverage ratio and a minimum interest coverage ratio. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Revolving Credit Facility.” The Revolver will limit our ability to make certain payments, including dividends or distributions on Fluence Energy, LLC’s equity and other restricted payments, provided, however, that payments in respect of certain tax distributions under the Fluence Energy LLC Agreement and certain payments under the TRA will be permitted. These restrictions may restrict our current and future operations, particularly our ability to respond to certain changes in our business or

TABLE OF CONTENTS

industry, or take future actions. In connection with the Revolver, we will grant the lenders party thereto a security interest in substantially all of our assets.

Our ability to meet these restrictive covenants can be impacted by events beyond our control and we may be unable to do so. Our Revolver and related security agreements will provide that our breach or failure to satisfy certain covenants constitutes an event of default. Upon the occurrence of an event of default, our lenders could elect to declare all amounts outstanding under its debt agreements to be immediately due and payable. In addition, our lenders would have the right to proceed against the assets we provided as collateral pursuant to the Revolver and related security agreement. If the debt under our Revolver was to be accelerated, we may not have sufficient cash on hand or be able to sell sufficient collateral to repay it, which would have an immediate adverse effect on our business and operating results. This could potentially cause us to cease operations and result in a complete loss of your investment in our Class A common stock.

Moreover, the new Revolver will require us to dedicate a portion of our cash flow from operations to interest payments, thereby reducing the availability of cash flow to fund working capital, capital expenditures and other general corporate purposes; increasing our vulnerability to adverse general economic, industry, or competitive developments or conditions; and limiting our flexibility in planning for, or reacting to, changes in our business and the industry in which we operate or in pursuing our strategic objectives.

Our future capital needs are uncertain and we may need to raise additional funds in the future, and such funds may not be available on acceptable terms or at all.

We believe that our current cash and cash equivalents, including the net proceeds from this offering together with our expected cash from operations, will be sufficient to meet our projected operating requirements for the foreseeable future. However, continued expansion of our business will be expensive, and we may seek additional funds from public and private stock offerings, borrowings under our existing or new credit facilities or other sources which we may not be able to maintain or obtain on acceptable or commercially reasonable terms, if at all. Our capital requirements will depend on many factors, including:

•

market acceptance of our offerings;

•

the revenue generated by sales of our offerings;

•

the costs associated with expanding our sales and marketing efforts;

•

the expenses we incur in manufacturing and selling our products;

•

the costs of developing and commercializing new products or technologies;

•

the cost of filing and prosecuting patent applications and defending and enforcing our patent and other intellectual property rights;

•

the cost of defending, in litigation or otherwise, any claims that we infringe third-party patent or other intellectual property rights;

•

the cost of enforcing or defending against non-competition claims;

•

the number and timing of acquisitions and other strategic transactions;

•

the costs associated with our planned international expansion; and

•

unanticipated general and administrative expenses.

As a result of these factors, we may seek to raise additional capital to, among others:

•

maintain appropriate product inventory levels;

•

continue our research and development and protect our intellectual property rights;

•

defend claims, in litigation or otherwise;

•

expand our geographic reach;

•

commercialize our new products; and

•

acquire companies and license products or intellectual property.

TABLE OF CONTENTS

Such capital may not be available on favorable terms, or at all. Furthermore, if we issue equity or debt securities to raise additional capital, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences, and privileges senior to those of our existing stockholders. In addition, if we raise additional capital through collaboration, licensing, or other similar arrangements, it may be necessary to relinquish valuable rights to our products, potential products, or proprietary technologies, or grant licenses on terms that are not favorable to us. Historically, we have relied on parent corporate guarantees from our affiliates to support project sales. If we are unable to rely on our standalone credit quality or utilize such parent corporate guarantees going forward, it may impact our ability to sell products or establish supplier relationships going forward. If we cannot raise capital on acceptable terms, we may not be able to develop or enhance our products, execute our business plan, take advantage of future opportunities, or respond to competitive pressures, changes in our supplier relationships, or unanticipated customer requirements. Any of these events could adversely affect our ability to achieve our development and commercialization goals, which could have a material adverse effect on our business, results of operations, and financial condition.

Risks Related to Our Intellectual Property and Technology

If we are unable to obtain, maintain and enforce intellectual property protection for our technology or if the scope of our intellectual property protection is not sufficiently broad, others may be able to develop and commercialize technology substantially similar to ours, and our ability to successfully commercialize our technology may be adversely affected.

Our business depends on internally developed technology, including hardware, software, databases, confidential information and know-how, the protection of which is crucial to the success of our business. We rely on a combination of trademark, trade-secret, and copyright laws and confidentiality procedures and contractual provisions to protect our intellectual property rights in our internally developed technology. We may, over time, increase our investment in protecting our intellectual property through additional trademark, patent, and other intellectual property filings that could be expensive and time-consuming. Effective trademark, trade-secret, and copyright protection is expensive to develop and maintain, both in terms of initial and ongoing registration requirements and the costs of defending our rights. These measures, however, may not be sufficient to offer us meaningful protection. If we are unable to protect our intellectual property and other rights, our competitive position and our business could be harmed, as third parties may be able to commercialize and use technologies and software products that are substantially the same as ours without incurring the development and licensing costs that we have incurred. Any of our owned or licensed intellectual property rights could be challenged, invalidated, circumvented, infringed, or misappropriated, our trade secrets and other confidential information could be disclosed in an unauthorized manner to third parties, or our intellectual property rights may not be sufficient to permit us to take advantage of current market trends or otherwise to provide us with competitive advantages, which could result in costly redesign efforts, discontinuance of certain offerings, or other competitive harm.

Monitoring unauthorized use of our intellectual property is difficult and costly. From time to time, we seek to analyze our competitors’ services, and may in the future seek to enforce our rights against potential infringement. However, the steps we have taken to protect our intellectual property rights may not be adequate to prevent infringement or misappropriation of our intellectual property. We may not be able to detect unauthorized use of, or take appropriate steps to enforce, our intellectual property rights. Any inability to meaningfully protect our intellectual property rights could result in harm to our ability to compete and reduce demand for our technology. Moreover, our failure to develop and properly manage new intellectual property could adversely affect our market positions and business opportunities. Also, some of our services rely on technologies and software developed by or licensed from third parties, and we may not be able to maintain our relationships with such third parties or enter into similar relationships in the future on reasonable terms or at all.

Uncertainty may result from changes to intellectual property legislation and from interpretations of intellectual property laws by applicable courts and agencies. Accordingly, despite our efforts, we may be unable to obtain and maintain the intellectual property rights necessary to provide us with a competitive advantage. Our failure to obtain, maintain and enforce our intellectual property rights could therefore have a material adverse effect on our business, financial condition, and results of operations.

TABLE OF CONTENTS

We may be sued by third parties for infringement, misappropriation, dilution, or other violation of their intellectual property or proprietary rights.

Internet, advertising, and e-commerce companies frequently are subject to litigation based on allegations of infringement, misappropriation, dilution, or other violations of intellectual property rights. Some internet, advertising, and e-commerce companies, including some of our competitors, as well as non-practicing entities, own large numbers of patents, copyrights, trademarks, and trade secrets, which they may use to assert claims against us.

Third parties may in the future assert, that we have infringed, misappropriated, diluted, or otherwise violated their intellectual property rights. For instance, the use of our technology to provide our offerings could be challenged by claims that such use infringes, dilutes, misappropriates, or otherwise violates the intellectual property rights of a third party. In addition, we may in the future be exposed to claims that content published or made available through our apps or websites violates third-party intellectual property rights.

As we face increasing competition and as a public company, the possibility of intellectual property rights claims against us grows. Such claims and litigation may involve patent holding companies or other adverse intellectual property rights holders who have no relevant product revenue, and therefore our own pending patents and other intellectual property rights may provide little or no deterrence to these rights holders in bringing intellectual property rights claims against us. There may be intellectual property rights held by others, including issued or pending patents and trademarks, that cover significant aspects of our technologies, content, branding, or business methods, and we cannot assure that we are not infringing or violating, and have not violated or infringed, any third-party intellectual property rights or that we will not be held to have done so or be accused of doing so in the future. We expect that we may receive in the future notices that claim we or our partners, or clients using our solutions and services, have misappropriated, or misused other parties’ intellectual property rights, particularly as the number of competitors in our market grows and the functionality of applications amongst competitors overlaps.

Any claim that we have violated intellectual property or other proprietary rights of third parties, with or without merit, and whether or not it results in litigation, is settled out of court or is determined in our favor, could be time-consuming and costly to address and resolve, and could divert the time and attention of management and technical personnel from our business. Furthermore, an adverse outcome of a dispute may result in an injunction and could require us to pay substantial monetary damages, including treble damages and attorneys’ fees, if we are found to have willfully infringed a party’s intellectual property rights. Any settlement or adverse judgment resulting from such a claim could require us to enter into a licensing agreement to continue using the technology, content, or other intellectual property that is the subject of the claim; restrict or prohibit our use of such technology, content, or other intellectual property; require us to expend significant resources to redesign our technology or solutions; and require us to indemnify third parties. Royalty or licensing agreements, if required or desirable, may be unavailable on terms acceptable to us, or at all, and may require significant royalty payments and other expenditures. We may also be required to develop alternative non-infringing technology, which could require significant time and expense. There also can be no assurance that we would be able to develop or license suitable alternative technology, content, or other intellectual property to permit us to continue offering the affected technology, content, or services to our partners or clients. If we cannot develop or license technology for any allegedly infringing aspect of our business, we would be forced to limit our product or service offerings and may be unable to compete effectively. Any of these events could materially harm our business, financial condition, and results of operations.

If our trademarks and trade names are not adequately protected or protectable, we may not be able to build name recognition in our markets of interest, and our competitive position may be harmed.

The registered or unregistered trademarks or trade names that we own may be challenged, infringed, circumvented, declared generic, lapsed, or determined to be infringing on or dilutive of other marks. We may not be able to protect our rights in these trademarks and trade names, which we need in order to build name recognition with potential members, partners, and clients. In addition, third parties may file for registration of trademarks similar or identical to our trademarks, thereby impeding our ability to build brand identity and possibly leading to market confusion. If they succeed in registering or developing common-law rights in such trademarks, and if we are not successful in challenging such third-party rights, we may

TABLE OF CONTENTS

not be able to use these trademarks to develop brand recognition of our technologies, products, or services. In addition, there could be potential trade name or trademark infringement claims brought by owners of other registered or unregistered trademarks or trademarks that incorporate variations of our registered or unregistered trademarks or trade names. If we are unable to establish name recognition based on our trademarks and trade names, we may not be able to compete effectively, which could have a material adverse effect on our business, financial condition, results of operations and prospects.

We may not be able to enforce our intellectual property rights throughout the world.

We may also be required to protect our proprietary technology and content in an increasing number of jurisdictions, a process that is expensive and may not be successful, or which we may not pursue in every location. Filing, prosecuting, maintaining, defending, and enforcing intellectual property rights on our products, services, and technologies in all countries throughout the world could be prohibitively expensive, and our intellectual property rights in some countries outside the United States can be less extensive than those in the United States. We do not own and have not registered or applied for intellectual property registrations in all countries outside the United States. Competitors may use our technologies in jurisdictions where we have not obtained protection to develop their own products and services and, further, may export otherwise violating products and services to territories where we have protection but enforcement is not as strong as that in the United States. These products and services may compete with our solutions and services, and our intellectual property rights may not be effective or sufficient to prevent them from competing. In addition, the laws of some foreign countries do not protect certain proprietary rights to the same extent as the laws of the United States, and many companies have encountered significant challenges in establishing and enforcing certain of their proprietary rights outside of the United States. These challenges can be caused by the absence or inconsistency of the application of rules and methods for the establishment and enforcement of intellectual property rights outside of the United States. For instance, there is no uniform worldwide policy regarding patentable subject matter or the scope of claims allowable for business methods. As such, we do not know the degree of future protection that we will have on our technologies, products, and services.

In addition, the legal systems of some countries, particularly developing countries, do not favor the enforcement of certain intellectual property protection. This could make it difficult for us to stop the misappropriation or other violation of certain of our other intellectual property rights. Accordingly, we may choose not to seek protection in certain countries, and we will not have the benefit of protection in such countries. Proceedings to enforce our intellectual property rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business. Accordingly, our efforts to protect our intellectual property rights in such countries may be inadequate. In addition, changes in the law and legal decisions by courts in the United States and foreign countries may affect our ability to obtain adequate protection for our products, services, and other technologies and the enforcement of intellectual property. Any of the foregoing could harm our competitive position, business, financial condition, results of operations, and prospects.

We may be subject to claims that our employees, consultants, or advisors have wrongfully used or disclosed alleged trade secrets of their current or former employers or claims asserting ownership of what we regard as our own intellectual property.

Many of our employees, consultants, and advisors are currently or were previously employed at other companies in our field, including our competitors or potential competitors. Although we try to ensure that our employees, consultants, and advisors do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these individuals have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual’s current or former employer. Litigation may be necessary to defend against these claims. If we fail in defending any such claims, in addition to paying monetary damages, we may lose valuable intellectual property rights or personnel. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

In addition, while it is our policy to require our employees and contractors who may be involved in the conception or development of intellectual property to execute agreements assigning such intellectual property

TABLE OF CONTENTS

to us, we may be unsuccessful in executing such an agreement with each party who, in fact, conceives or develops intellectual property that we regard as our own. The assignment of intellectual property rights may not be self-executing, or the assignment agreements may be breached, and we may be forced to bring claims against third parties, or defend claims that they may bring against us, to determine the ownership of what we regard as our intellectual property. Any of the foregoing could harm our competitive position, business, financial condition, results of operations, and prospects.

Our business depends on our ability to effectively invest in, implement improvements to and properly maintain the uninterrupted operation and data integrity of our information technology and other business systems.

Our business is highly dependent on maintaining effective information systems as well as the integrity and of the data we use to serve our customers and operate our business. Because of the large amount of data that we collect and manage, it is possible that hardware failures or errors in our systems could result in data loss or corruption or cause the information that we collect to be incomplete or contain inaccuracies that our partners regard as significant. If our data were found to be inaccurate or unreliable due to fraud or other error, or if we, or any of the third-party service providers we engage, were to fail to maintain information systems and data integrity effectively, we could experience operational disruptions that may impact our operations and hinder our ability to provide services, establish appropriate pricing for services, establish reserves, report financial results timely and accurately and maintain regulatory compliance, among other things. If any such failure of our data integrity were to result in the theft, corruption or other harm to the data of our customers, our ability to retain and attract partners or customers may be harmed.

We must continue to invest in long-term solutions that will enable us to anticipate customer needs and expectations, enhance the customer experience, act as a differentiator in the market, and protect against cybersecurity risks and threats. Despite our implementation of reasonable security measures, our IT systems, like those of other companies, are vulnerable to damages from computer viruses, natural disasters, fire, power loss, telecommunications failures, personnel misconduct, human error, unauthorized access, physical or electronic security breaches, cyber-attacks (including malicious and destructive code, phishing attacks, ransomware, and denial of service attacks), and other similar disruptions. Such attacks or security breaches may be perpetrated by bad actors internally or externally (including computer hackers, persons involved with organized crime, or foreign state or foreign state-supported actors). Cybersecurity threat actors employ a wide variety of methods and techniques that are constantly evolving, increasingly sophisticated, and difficult to detect and successfully defend against. We have experienced such incidents in the past, and any future incidents could expose us to claims, litigation, regulatory or other governmental investigations, administrative fines, and potential liability. Any system failure, accident, or security breach could result in disruptions to our operations. A material network breach in the security of our IT systems could include the theft of our trade secrets, customer information, human resources information, or other confidential data, including but not limited to personally identifiable information.

Although past incidents have not had a material effect on our business operations or financial performance, to the extent that any disruption or security breach results in a loss or damage to our data, or an inappropriate disclosure of confidential, proprietary or customer information, it could cause significant damage to our reputation, affect our relationships with our customers and strategic partners, lead to claims against us from governments and private plaintiffs, and adversely affect our business. We cannot guarantee that future cyberattacks, if successful, will not have a material effect on our business or financial results.

Many governments have enacted laws requiring companies to provide notice of cyber incidents involving certain types of data, including personal data. These laws may be subject to alterations and revisions, and if we fail to comply with our obligations under such laws in the jurisdictions in which we operate, we could be subject to regulatory action and lawsuits. If an actual or perceived cybersecurity breach of security measures, unauthorized access to our system or the systems of the third-party vendors that we rely upon, or any other cybersecurity threat occurs, we may incur liability, costs, or damages, contract termination, our reputation may be compromised, our ability to attract new customers could be negatively affected, and our business, financial condition, and results of operations could be materially and adversely affected. Any compromise of our security could also result in a violation of applicable domestic and foreign security, privacy or data protection, consumer protection, and other laws, regulatory or other governmental investigations, enforcement actions, and legal and financial exposure, including potential

TABLE OF CONTENTS

contractual liability. In addition, we may be required to incur significant costs to protect against and remediate damage caused by these disruptions or security breaches in the future.

We utilize open-source software, which may pose particular risks to our proprietary software and solutions.

We use open-source software in our solutions and will use open-source software in the future. Companies that incorporate open-source software into their solutions have, from time to time, faced claims challenging the use of open-source software and compliance with open-source license terms. Some licenses governing the use of open-source software contain requirements that we make available source code for modifications or derivative works we create based upon the open-source software, and that we license such modifications or derivative works under the terms of a particular open-source license or other license granting third parties certain rights of further use. By the terms of certain open-source licenses, we could be required to release the source code of our proprietary software, and to make our proprietary software available under open-source licenses to third parties at no cost, if we combine our proprietary software with open-source software in certain manners. Although we monitor our use of open-source software, we cannot assure you that all open-source software is reviewed prior to use in our solutions, that our developers have not incorporated open-source software into our solutions, or that they will not do so in the future. Additionally, the terms of many open-source licenses to which we are subject have not been interpreted by U.S. or foreign courts. There is a risk that open-source software licenses could be construed in a manner that imposes unanticipated conditions or restrictions on our ability to market or provide our solutions as currently marketed or provided. Companies that incorporate open-source software into their products have, in the past, faced claims seeking enforcement of open-source license provisions and claims asserting ownership of open-source software incorporated into their product. If an author or other third party that distributes such open-source software were to allege that we had not complied with the conditions of an open-source license, we could incur significant legal costs defending ourselves against such allegations. In the event such claims were successful, we could be subject to significant damages or be enjoined from the distribution of our software. In addition, the terms of open-source software licenses may require us to provide source code that we develop using such open-source software to others on unfavorable license terms. As a result of our current or future use of open-source software, we may face claims or litigation, be required to release our proprietary source code, pay damages for breach of contract, re-engineer our solutions, discontinue making our solutions available in the event re-engineering cannot be accomplished on a timely basis, or take other remedial action. Any such re-engineering or other remedial efforts could require significant additional research and development resources, and we may not be able to successfully complete any such re-engineering or other remedial efforts. Further, in addition to risks related to license requirements, use of certain open-source software can lead to greater risks than use of third-party commercial software, as open-source licensors generally do not provide warranties or controls on the origin of software. Any of these risks could be difficult to eliminate or manage, and, if not addressed, could have a negative effect on our business, financial condition, and results of operations.

If we fail to comply with our obligations under license or technology agreements with third parties, we may be required to pay damages, and we could lose license rights that are critical to our business. If we fail to comply with our obligations under license and technology agreements with AES and Siemens, we could lose license rights, including to patents and patent applications, which may prove to be material to our business.

We license certain intellectual property, including patents, technologies and software from third parties, including AES and Siemens, that is important to our business, and in the future, we may enter into additional agreements that provide us with licenses to valuable intellectual property or technology. If we fail to comply with any of the obligations under our license agreements, we may be required to pay damages and the licensor may have the right to terminate the license. Termination by the licensor would cause us to lose valuable rights, and could prevent us from selling our products and services, or adversely impact our ability to commercialize future solutions and services. Our business would suffer if any current or future licenses terminate, if the licensors fail to abide by the terms of the license, if the licensors fail to enforce licensed patents against infringing third parties, if the licensed intellectual property is found to be invalid or unenforceable, if the licensed intellectual property expires or if we are unable to enter into necessary licenses on acceptable terms. In addition, our rights to certain intellectual property, technologies, and software, are licensed to us on a non-exclusive basis. The owners of these non-exclusively licensed technologies are therefore free to license them to third parties, including our competitors, on terms that may be superior

TABLE OF CONTENTS

to those offered to us, which could place us at a competitive disadvantage. Moreover, our licensors may own or control intellectual property that has not been licensed to us and, as a result, we may be subject to claims, regardless of their merit, that we are infringing or otherwise violating the licensor’s rights. In addition, the agreements under which we license intellectual property or technology from third parties are generally complex, and certain provisions in such agreements may be susceptible to multiple interpretations. The resolution of any contract interpretation disagreement that may arise could narrow what we believe to be the scope of our rights to the relevant intellectual property or technology, or increase what we believe to be our financial or other obligations under the relevant agreement. Any of the foregoing could harm our competitive position, business, financial condition, results of operations, and prospects.

If we cannot license rights to use technologies on reasonable terms, we may not be able to commercialize new solutions or services in the future.

In the future, we may identify additional third-party intellectual property we may need to license in order to engage in our business, including to develop or commercialize new products or services. However, such licenses may not be available on acceptable terms or at all. The licensing or acquisition of third-party intellectual property rights is a competitive area, and several more established companies may pursue strategies to license or acquire third-party intellectual property rights that we may consider attractive or necessary. These established companies may have a competitive advantage over us due to their size, capital resources, and greater development or commercialization capabilities. In addition, companies that perceive us to be a competitor may be unwilling to assign or license rights to us. Even if such licenses are available, we may be required to pay the licensor substantial royalties based on sales of our products and services. Such royalties are a component of the cost of our products or services and may affect the margins on our products and services. In addition, such licenses may be non-exclusive, which could give our competitors access to the same intellectual property licensed to us. If we are unable to enter into the necessary licenses on acceptable terms or at all, if any necessary licenses are subsequently terminated, if our licensors fail to abide by the terms of the licenses, if our licensors fail to prevent infringement by third parties, or if the licensed intellectual property rights are found to be invalid or unenforceable, or if the licensed intellectual property rights expire, our business, financial condition, results of operations, and prospects could be affected. If licenses to third-party intellectual property rights are or become required for us to engage in our business, the rights may be non-exclusive, which could give our competitors access to the same technology or intellectual property rights licensed to us. Moreover, we could encounter delays and other obstacles in our attempt to develop alternatives. Defense of any lawsuit or failure to obtain any of these licenses on favorable terms could prevent us from commercializing solutions and services, which could harm our competitive position, business, financial condition, results of operations, and prospects.

Risks related to the Offering and Ownership of our Class A Common Stock

Certain provisions of Delaware law and antitakeover provisions in our organizational documents could delay or prevent a change of control.

Certain provisions of Delaware law, our amended and restated certificate of incorporation, amended and restated bylaws, and our Stockholders Agreement may have an antitakeover effect and may delay, defer, or prevent a merger, acquisition, tender offer, takeover attempt, or other change of control transaction that a stockholder might consider in its best interest, including those attempts that might result in a premium over the market price for the shares held by our stockholders. These provisions provide for, among other things:

•

the ability of our board of directors to issue one or more series of preferred stock;

•

advance notice for nominations of directors by stockholders and for stockholders to include matters to be considered at our annual meetings;

•

certain limitations on convening special stockholder meetings;

•

prohibit cumulative voting in the election of directors;

•

that certain provisions of amended and restated certificate of incorporation may be amended only by the affirmative vote of at least 66 2/3% of the voting power represented by our then-outstanding common stock;

TABLE OF CONTENTS

•

the right of each of AES Grid Stability, Siemens Industry, and the Blocker Shareholder to nominate certain of our directors;

•

the shares of our Class B-1 common stock that will be held by our Founders entitle them to five votes per share on all matters presented to our stockholders generally; and

•

the consent rights of the Continuing Equity Owners in the Stockholders Agreement as described in “Certain Relationships and Related Party Transactions — Stockholders Agreement.”

These antitakeover provisions could make it more difficult for a third party to acquire us, even if the third party’s offer may be considered beneficial by many of our stockholders. As a result, our stockholders may be limited in their ability to obtain a premium for their shares.

In addition, we have opted out of Section 203 of the General Corporation Law of the State of Delaware, which we refer to as the DGCL, but our amended and restated certificate of incorporation will provide that engaging in any of a broad range of business combinations with any “interested” stockholder (any stockholder with 15% or more of our voting stock) for a period of three years following the date on which the stockholder became an “interested” stockholder is prohibited, subject to certain exceptions. See “Description of Capital Stock.”

The JOBS Act will allow us to postpone the date by which we must comply with certain laws and regulations intended to protect investors and to reduce the amount of information we provide in our reports filed with the SEC. We cannot be certain if this reduced disclosure will make our Class A common stock less attractive to investors.

The JOBS Act is intended to reduce the regulatory burden on “emerging growth companies.” As defined in the JOBS Act, a public company whose initial public offering of common equity securities occurs after December 8, 2011, and whose annual net revenues are less than $1.07 billion will, in general, qualify as an “emerging growth company” until the earliest of:

•

the last day of its fiscal year following the fifth anniversary of the date of its initial public offering of common equity securities;

•

the last day of its fiscal year in which it has annual gross revenue of $1.07 billion or more;

•

the date on which it has, during the previous three-year period, issued more than $1.07 billion in nonconvertible debt; and

•

the date on which it is deemed to be a “large accelerated filer,” which will occur at such time as the company (1) has an aggregate worldwide market value of common equity securities held by non-affiliates of $700 million or more as of the last business day of its most recently completed second fiscal quarter, (2) has been required to file annual and quarterly reports under the Securities Exchange Act of 1934, as amended, or the Exchange Act, for a period of at least 12 months, and (3) has filed at least one annual report pursuant to the Exchange Act.

Under this definition, we will be an “emerging growth company” upon completion of this offering and could remain an “emerging growth company” until as late as the fifth anniversary of the completion of this offering. For so long as we are an “emerging growth company,” we will, among other things:

•

not be required to comply with the auditor attestation requirements of Section 404(b) of the Sarbanes-Oxley Act;

•

not be required to hold a nonbinding advisory stockholder vote on executive compensation pursuant to Section 14A(a) of the Exchange Act;

•

not be required to seek stockholder approval of any golden parachute payments not previously approved pursuant to Section 14A(b) of the Exchange Act;

•

be exempt from the requirement of the Public Company Accounting Oversight Board, or PCAOB, regarding the communication of critical audit matters in the auditor’s report on the financial statements; and

TABLE OF CONTENTS

•

be subject to reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements.

In addition, Section 107 of the JOBS Act provides that an emerging growth company can use the extended transition period provided in Section 7(a)(2)(B) of the Securities Act for complying with new or revised accounting standards. This permits an emerging growth company to delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to use this extended transition period and, as a result, our consolidated financial statements may not be comparable to the financial statements of issuers who are required to comply with the effective dates for new or revised accounting standards that are applicable to public companies.

We cannot predict if investors will find our Class A common stock less attractive as a result of our decision to take advantage of some or all of the reduced disclosure requirements above. If some investors find our Class A common stock less attractive as a result, there may be a less active trading market for our Class A common stock and our stock price may be more volatile.

Because we have no current plans to pay regular cash dividends on our Class A common stock following this offering, you may not receive any return on investment unless you sell your Class A common stock for a price greater than that which you paid for it.

We do not anticipate paying any regular cash dividends on our Class A common stock following this offering. Any decision to declare and pay dividends in the future will be made at the discretion of our board of directors and will depend on, among other things, general and economic conditions, our results of operations and financial condition, our available cash and current and anticipated cash needs, capital requirements, contractual, legal, tax and regulatory restrictions, and such other factors that our board of directors may deem relevant. In addition, our ability to pay dividends is, and may be, limited by covenants of any future outstanding indebtedness we or our subsidiaries incur. Therefore, any return on investment in our Class A common stock is solely dependent upon the appreciation of the price of our Class A common stock on the open market, which may not occur. See “Dividend Policy” for more detail.

We cannot predict the effect our multiple class structure may have on the market price of our Class A common stock.

We cannot predict whether our multiple class structure will result in a lower or more volatile market price of our Class A common stock, in adverse publicity, or other adverse consequences. For example, certain index providers have announced restrictions on including companies with multiple-class share structures in certain of their indices. In July 2017, FTSE Russell announced that it plans to require new constituents of its indices to have greater than 5% of the company’s voting rights in the hands of public stockholders, and S&P Dow Jones announced that it will no longer admit companies with multiple-class share structures to certain of its indices. Affected indices include the Russell 2000 and the S&P 500, S&P MidCap 400, and S&P SmallCap 600, which together make up the S&P Composite 1500. Also in 2017, MSCI, a leading stock index provider, opened public consultations on their treatment of no-vote and multi-class structures and temporarily barred new multi-class listings from certain of its indices and in October 2018, MSCI announced its decision to include equity securities “with unequal voting structures” in its indices and to launch a new index that specifically includes voting rights in its eligibility criteria. Under such announced policies, the multiple class structure of our stock would make us ineligible for inclusion in certain indices and, as a result, mutual funds, exchange-traded funds, and other investment vehicles that attempt to track those indices would not invest in our Class A common stock. These policies are relatively new, and it is unclear what effect, if any, they will have on the valuations of publicly traded companies excluded from such indices, but it is possible they may depress valuations, compared to similar companies that are included. Given the sustained flow of investment funds into passive strategies that seek to track certain indices, exclusion from certain stock indices would likely preclude investment by many of these funds and could make our Class A common stock less attractive to other investors. As a result, the market price of our Class A common stock could be adversely affected.

We are a “controlled company” within the meaning of the Nasdaq rules and, as a result, will qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You may not have the same protections afforded to stockholders of companies that are subject to such corporate governance requirements.

After the consummation of the Transactions, our Continuing Equity Owners will have more than 50% of the voting power for the election of directors, and, as a result, we will be considered a “controlled

TABLE OF CONTENTS

company” for the purposes of the Nasdaq rules. As such, we will qualify for, and intend to rely on, exemptions from certain corporate governance requirements, including the requirements to have a majority of independent directors on our board of directors, an entirely independent compensation committee or to have director nominations be made, or recommended to the full board of directors, by its independent directors or by a nominations committee that is composed entirely of independent directors.

The corporate governance requirements and, specifically, the independence standards are intended to ensure directors who are considered independent are free of any conflicting interest that could influence their actions as directors. Following this offering, we intend to utilize certain exemptions afforded to a “controlled company.” As a result, we will not be subject to certain corporate governance requirements, including that a majority of our board of directors consists of “independent directors,” as defined under the rules of the Nasdaq. In addition, we are not required to have director nominations be made, or recommended to the full board of directors, by its independent directors or by a nominations committee that is composed entirely of independent directors.

Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the Nasdaq rules. Our status as a controlled company could make our Class A common stock less attractive to some investors or otherwise harm our stock price.

No market currently exists for our Class A common stock, and an active, liquid trading market for our Class A common stock may not develop, which may cause our Class A common stock to trade at a discount from the initial offering price and make it difficult for you to sell the Class A common stock you purchase.

Prior to this offering, there has not been a public market for our Class A common stock. We cannot predict the extent to which investor interest in us will lead to the development of a trading market or how active and liquid that market may become. If an active and liquid trading market does not develop or continue, you may have difficulty selling any of our Class A common stock that you purchase at a price above the price you purchase it or at all. The initial public offering price for the shares was determined by negotiations between us and the underwriters and may not be indicative of prices that will prevail in the open market following this offering. The failure of an active and liquid trading market to develop and continue would likely have a material adverse effect on the value of our Class A common stock. The market price of our Class A common stock may decline below the initial offering price, and you may not be able to sell your shares of our Class A common stock at or above the price you paid in this offering, or at all. An inactive market may also impair our ability to raise capital to continue to fund operations by selling shares and may impair our ability to acquire other companies or technologies by using our shares as consideration.

Our amended and restated certificate of incorporation will provide that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for certain stockholder litigation matters, and the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, employees or stockholders.

Our amended and restated certificate of incorporation will provide (A) (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any current or former director, officer, other employee or stockholder of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws (as either may be amended or restated) or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware or (iv) any action asserting a claim governed by the internal affairs doctrine of the law of the State of Delaware shall, to the fullest extent permitted by law, be exclusively brought in the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, the federal district court of the State of Delaware; and (B) the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, the exclusive forum provision shall not apply to claims seeking to enforce any liability or duty created by the Exchange Act. The choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for

TABLE OF CONTENTS

disputes with us or our directors, officers, or other employees, which may discourage such lawsuits against us and our directors, officers, and other employees. Alternatively, if a court were to find the choice of forum provision contained in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, results of operations, and financial condition. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in our amended and restated certificate of incorporation.

Our amended and restated certificate of incorporation provides that the doctrine of “corporate opportunity” will not apply with respect to any director or stockholder who is not employed by us or our subsidiaries.

The doctrine of corporate opportunity generally provides that a corporate fiduciary may not develop an opportunity using corporate resources, acquire an interest adverse to that of the corporation or acquire property that is reasonably incident to the present or prospective business of the corporation or in which the corporation has a present or expectancy interest, unless that opportunity is first presented to the corporation and the corporation chooses not to pursue that opportunity. The doctrine of corporate opportunity is intended to preclude officers or directors or other fiduciaries from personally benefiting from opportunities that belong to the corporation. Our amended and restated certificate of incorporation, which will be in effect upon the consummation of the Transactions, will provide that the doctrine of “corporate opportunity” will not apply with respect to any director or stockholder who is not employed by us or our subsidiaries. Any director or stockholder who is not employed by us or our subsidiaries will, therefore, have no duty to communicate or present corporate opportunities to us, and will have the right to either hold any corporate opportunity for their (and their affiliates’) own account and benefit or to recommend, assign or otherwise transfer such corporate opportunity to persons other than us, including to any director or stockholder who is not employed by us or our subsidiaries.

As a result, certain of our stockholders, directors, and their respective affiliates, including AES Grid Stability, Siemens Industry, the Blocker Shareholder, and any of our directors nominated by them that is not employed by us or our subsidiaries, will not be prohibited from operating or investing in competing businesses. We, therefore, may find ourselves in competition with certain of our stockholders, directors, or their respective affiliates, and we may not have knowledge of, or be able to pursue, transactions that could potentially be beneficial to us. Accordingly, we may lose a corporate opportunity or suffer competitive harm, which could negatively impact our business, operating results, and financial condition.

If securities analysts do not publish research or reports about our business or if they downgrade our stock or our sector, or if there is any fluctuation in our credit rating, our stock price and trading volume could decline.

The trading market for our Class A common stock will rely in part on the research and reports that industry or financial analysts publish about us or our business. We do not control these analysts. Securities and industry analysts do not currently, and may never, publish research on our company. If no securities or industry analysts commence coverage of us, the trading price of our shares would likely be negatively impacted. Furthermore, if one or more of the analysts who do cover us downgrade our stock or our industry, or the stock of any of our competitors, or publish inaccurate or unfavorable research about our business, the price of our stock could decline. If one or more of these analysts stops covering us or fails to publish reports on us regularly, we could lose visibility in the market, which, in turn, could cause our stock price or trading volume to decline.

Additionally, any fluctuation in the credit rating of us or our subsidiaries may impact our ability to access debt markets in the future or increase our cost of future debt, which could have a material adverse effect on our operations and financial condition, which in return may adversely affect the trading price of shares of our Class A common stock.

Future sales, or the perception of future sales, by us or our existing stockholders in the public market following this offering could cause the market price for our Class A common stock to decline.

After this offering, the sale of shares of our Class A common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our Class A

TABLE OF CONTENTS

common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

Upon consummation of the Transactions, we will have outstanding a total of 49,493,275 shares of Class A common stock. Of the outstanding shares, the 31,000,000 shares sold in this offering (or 35,650,000 shares if the underwriters exercise in full their option to purchase additional shares) will be freely tradable without restriction or further registration under the Securities Act, other than any shares held by our affiliates. In addition, the shares of Class A common stock issued to the Blocker Shareholder in the Transactions will be eligible for resale pursuant to Rule 144 without restriction or further registration under the Securities Act, other than affiliate restrictions under Rule 144. Any shares of Class A common stock held by our affiliates will be eligible for resale pursuant to Rule 144 under the Securities Act, subject to the volume, manner of sale, holding period and other limitations of Rule 144.

Our directors and executive officers, and substantially all of our stockholders have entered into lock-up agreements with the underwriters prior to the commencement of this offering pursuant to which each of these persons or entities, subject to certain exceptions, for a period of 180 days after the date of this prospectus, may not, without the prior written consent of J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC on behalf of the underwriters, (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Class A common stock or any securities convertible into or exercisable or exchangeable for Class A common stock; or (2) file any registration statement with the Securities and Exchange Commission relating to the offering of any Class A common stock or any securities convertible into or exercisable or exchangeable for Class A common stock; or (3) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Class A common stock, whether any such transaction described in clauses (1), (2), or (3) is to be settled by delivery of Class A common stock or such other securities, in cash or otherwise. See “Underwriting.”

In addition, we have reserved 12,267,403 shares of Class A common stock for issuance pursuant to equity incentives issued pursuant to the Existing Equity Plan which will convert upon effectiveness of this offering into options and other rights to acquire shares of Class A common stock. Further, we have reserved 2,220,968 shares of Class A common stock for issuance pursuant to phantom units issued pursuant to the Existing Phantom Equity Plan, which will convert into a right to receive cash or equity based upon the value of shares of Class A common stock. Finally, we have reserved 9,500,000 shares of Class A common stock for issuance under the 2021 Plan. Any Class A common stock that we issue under the 2021 Plan or other equity incentive plans that we may adopt in the future would dilute the percentage ownership held by the investors who purchase Class A common stock in this offering.

As restrictions on resale end or if these stockholders exercise their registration rights, the market price of our shares of Class A common stock could drop significantly if the holders of these shares sell them or are perceived by the market as intending to sell them. These factors could also make it more difficult for us to raise additional funds through future offerings of our shares of Class A common stock or other securities.

In the future, we may also issue securities in connection with investments, acquisitions or capital raising activities. In particular, the number of shares of our Class A common stock issued in connection with an investment or acquisition, or to raise additional equity capital, could constitute a material portion of our then-outstanding shares of our Class A common stock. Any such issuance of additional securities in the future may result in additional dilution to you, or may adversely impact the price of our Class A common stock.

Our stock price may change significantly following the offering, and you may not be able to resell shares of our Class A common stock at or above the price you paid or at all, and you could lose all or part of your investment as a result.

The initial public offering price for the shares was determined by negotiations between us and the underwriters. You may not be able to resell your shares at or above the initial public offering price due to a number of factors included herein, including the following:

•

results of operations that vary from the expectations of securities analysts and investors;

TABLE OF CONTENTS

•

results of operations that vary from those of our competitors;

•

changes in expectations as to our future financial performance, including financial estimates and investment recommendations by securities analysts and investors;

•

technology changes, changes in consumer behavior in our industry;

•

security breaches related to our systems or those of our affiliates or strategic partners;

•

changes in economic conditions for companies in our industry;

•

changes in market valuations of, or earnings and other announcements by, companies in our industry;

•

declines in the market prices of stocks generally, particularly those of energy storage providers;

•

strategic actions by us or our competitors;

•

announcements by us, our competitors or our strategic partners of significant contracts, new products, acquisitions, joint marketing relationships, joint ventures, other strategic relationships, or capital commitments;

•

changes in general economic or market conditions or trends in our industry or the economy as a whole and, in particular, in the energy storage environment;

•

changes in business or regulatory conditions;

•

future sales of our Class A common stock or other securities;

•

investor perceptions of the investment opportunity associated with our Class A common stock relative to other investment alternatives;

•

the public’s response to press releases or other public announcements by us or third parties, including our filings with the SEC;

•

announcements relating to litigation or governmental investigations;

•

guidance, if any, that we provide to the public, any changes in this guidance, or our failure to meet this guidance;

•

the development and sustainability of an active trading market for our stock;

•

changes in accounting principles; and

•

other events or factors, including those resulting from system failures and disruptions, natural disasters, war, acts of terrorism, an outbreak of highly infectious or contagious diseases, such as the COVID-19 pandemic, or responses to these events.

Furthermore, the stock market may experience extreme volatility that, in some cases, may be unrelated or disproportionate to the operating performance of particular companies. These broad market and industry fluctuations may adversely affect the market price of our Class A common stock, regardless of our actual operating performance. In addition, price volatility may be greater if the public float and trading volume of our Class A common stock is low.

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we were involved in securities litigation, it could have a substantial cost and divert resources and the attention of management from our business regardless of the outcome of such litigation.

If you purchase shares of Class A common stock in this offering, you will suffer immediate and substantial dilution of your investment.

The initial public offering price of our Class A common stock is substantially higher than the net tangible book value per share of our Class A common stock. Therefore, if you purchase shares of our Class A common stock in this offering, you will pay a price per share that substantially exceeds our net tangible book value per share after this offering. You will experience immediate dilution of $18.92 per share, representing the difference between our net tangible book value per share after giving effect to this offering

TABLE OF CONTENTS

and the initial public offering price. In addition, investors who purchase Class A common stock from us in this offering will have contributed 75.7% of the aggregate price paid by all purchasers of our outstanding equity but will own only approximately 18.6% of our outstanding equity after this offering. See “Dilution” for more detail, including the calculation of the net tangible book value per share of our Class A common stock.

Risks Related to Our Existing Shareholders

Our articles of incorporation limit our Continuing Equity Owners’ and their directors’ and officers’ liability to us or you for breach of fiduciary duty and could also prevent us from benefiting from corporate opportunities that might otherwise have been available to us.

Our articles of incorporation will provide that, subject to any contractual provision to the contrary, our Continuing Equity Owners will have no obligation to refrain from:

•

engaging in the same or similar business activities or lines of business as we do;

•

doing business with any of our clients, customers, vendors or lessors;

•

employing or otherwise engaging any of our officers or employees; or

•

making investments in any property in which we may make investments.

Under our articles of incorporation, neither Continuing Equity Owners nor any officer or director of Continuing Equity Owners, except as provided in our articles of incorporation, will be liable to us or to our stockholders for breach of any fiduciary duty by reason of any of these activities.

Any interests or expectancy in corporate opportunities which become known to (i) any of our directors or officers who are also directors, officers, employees or other affiliates of Continuing Equity Owners or their affiliates (except that we and our subsidiaries shall not be deemed affiliates of Continuing Equity Owners or its affiliates for the purposes of the provision), or dual persons, or (ii) our Continuing Equity Owners themselves, and which relate to the business of Fluence or may constitute a corporate opportunity for both our Continuing Equity Owners and us. Generally, neither our Continuing Equity Owners nor our directors or officers who are also dual persons will be liable to us or our stockholders for breach of any fiduciary duty by reason of the fact that any such person pursues or acquires any corporate opportunity for the account of our Continuing Equity Owners or their affiliates, directs, recommends, sells, assigns or otherwise transfers such corporate opportunity to Our Continuing Equity Owners or its affiliates, or does not communicate information regarding such corporate opportunity to us. The corporate opportunity provision may exacerbate conflicts of interest between our Continuing Equity Owners and us because the provision effectively permits one of our directors or officers who also serves as a director, officer, employee or other affiliate of Our Continuing Equity Owners to choose to direct a corporate opportunity to our Continuing Equity Owners instead of us.

Our Continuing Equity Owners will not be restricted from competing with us in the energy storage business, including as a result of acquiring a company that operates an energy storage business. Due to the significant resources of our Continuing Equity Owners, including their intellectual property (all of which our Continuing Equity Owners will retain and certain of which they will license to us under the IP License Agreements), financial resources, name recognition and know-how resulting from the previous management of our business, our Continuing Equity Owners could have a significant competitive advantage over us should it decide to utilize these resources to engage in the type of business we conduct, which may cause our operating results and financial condition to be materially adversely affected.

We are controlled by the Continuing Equity Owners, whose interests may differ from those of our public stockholders.

Immediately following this offering and the application of net proceeds from this offering, the Continuing Equity Owners will control approximately 92.2% of the combined voting power of our common stock through their ownership of both Class A common stock and Class B-1 common stock. The Continuing Equity Owners will, for the foreseeable future, have the ability to substantially influence us through their ownership position over corporate management and affairs. The Continuing Equity Owners

TABLE OF CONTENTS

are able to, subject to applicable law, and the voting arrangements described in “Certain Relationships and Related Party Transactions,” elect a majority of the members of our board of directors and control actions to be taken by us and our board of directors, including amendments to our certificate of incorporation and bylaws and approval of significant corporate transactions, including mergers and sales of substantially all of our assets. The directors so elected will have the authority, subject to the terms of our indebtedness and applicable rules and regulations, to issue additional stock, implement stock repurchase programs, declare dividends and make other decisions. It is possible that the interests of the Continuing Equity Owners may in some circumstances conflict with our interests and the interests of our other stockholders, including you. For example, the Continuing Equity Owners may have different tax positions from us, especially in light of the Tax Receivable Agreement, that could influence our decisions regarding whether and when to dispose of assets, whether and when to incur new or refinance existing indebtedness, and whether and when we should terminate the Tax Receivable Agreement and accelerate its obligations thereunder. In addition, the determination of future tax reporting positions and the structuring of future transactions may take into consideration the Continuing Equity Owners’ tax or other considerations, which may differ from the considerations of us or our other stockholders. See “Certain Relationships and Related Party Transactions—Tax Receivable Agreement.”

Certain of our officers and directors may have actual or potential conflicts of interest because of their positions with our Continuing Equity Owners.

Following this offering, Julian Nebreda, Lisa Krueger, Barbara Humpton, Emma Falck, Axel Meier, Chris Shelton and Simon Smith will serve on our board of directors and will retain their positions with AES, Siemens, or QIA, as applicable. These individuals’ holdings in and compensation from the Continuing Equity Owners may be significant for some of these persons. Their positions at AES, Siemens, or QIA, their compensation from AES, Siemens or QIA and the ownership of any equity or equity awards in AES, Siemens, or QIA, as applicable, may create the appearance of conflicts of interest when these individuals are faced with decisions that could have different implications for our Continuing Equity Owners than the decisions have for us.

We rely on our access to our Founders’ brands and reputation, some of our Founders’ relationships, and the brands and reputations of unaffiliated third parties.

We believe the association with our Founders has contributed to our building relationships with our customers due to their recognized brands and products, as well as resources such as their intellectual property and access to third parties’ intellectual property. Any perceived loss of our Founders’ scale, capital base and financial strength as a result of this offering, or any actual loss in the future, may prompt business partners to reprice, modify or terminate their relationships with us. In addition, our Founders’ reduction of their ownership of our company may cause some of our existing agreements and licenses to be terminated. We cannot predict with certainty the effect that this offering will have on our business.

Third parties may seek to hold us responsible for liabilities of our Founders, which could result in a decrease in our income.

Third parties may seek to hold us responsible for our Founders’ liabilities. If those liabilities are significant and we are ultimately held liable for them, we cannot assure that we will be able to recover the full amount of our losses from our Founders.

We may be required to pay additional taxes as a result of partnership tax audit rules.

We may be required to pay additional taxes as a result of partnership audit rules under U.S. federal and other applicable income tax law. The Bipartisan Budget Act of 2015 changed the rules applicable to U.S. federal income tax audits of partnerships, including entities such as Fluence Energy, LLC. Under these rules (which generally are effective for taxable years beginning after December 31, 2017), subject to certain exceptions, audit adjustments to items of income, gain, loss, deduction, or credit of an entity (and any holder’s share thereof) are determined, and taxes, interest, and penalties attributable thereto, are assessed and collected, at the partnership level. Although there is uncertainty about how these rules will continue to be implemented, it is possible that they could result in Fluence Energy, LLC (or any of its subsidiaries that are

TABLE OF CONTENTS

or have been treated as partnerships for U.S. federal income tax purposes) being required to pay additional taxes, interest, and penalties as a result of an audit adjustment, and we, as an owner of Fluence Energy, LLC (or as an indirect owner of such other entities), could be required to indirectly bear the economic burden of those taxes, interest, and penalties even if they relate to periods prior to this offering and even though we may not otherwise have been required to pay additional corporate-level taxes as a result of the related audit adjustment.

We may incur certain tax liabilities attributable to the Blocker Company as a result of the transactions contemplated to occur in connection with this offering.

In connection with the Transactions and pursuant to the Blocker Mergers, the Blocker Company will merge with and into us. See “Our Organizational Structure.” As the successor to the Blocker Company, we will generally succeed to and be responsible for any outstanding or historical liabilities, including tax liabilities, of the Blocker Company, including any liabilities that might be incurred as a result of the Blocker Mergers. Any such liabilities for which we are responsible could have an adverse effect on our liquidity and financial condition.

We may not achieve some or all of the anticipated benefits of being a standalone public company.

We may not be able to achieve all of the anticipated strategic and financial benefits expected as a result of being a standalone public company, or such benefits may be delayed or not occur at all. These anticipated benefits include the following:

•

allowing investors to evaluate the distinct merits, performance and future prospects of our business, independent of our Founders’ other businesses;

•

improving our strategic and operational flexibility and increasing management focus as we continue to implement our strategic plan and allowing us to respond more effectively to the competitive environment for our business;

•

allowing us to adopt a capital structure better suited to our financial profile and business needs, without competing for capital with our Founders’ other businesses;

•

creating an independent equity structure that will facilitate our ability to effect future acquisitions utilizing our capital stock; and

•

facilitating incentive compensation arrangements for employees more directly tied to the performance of our business, and enhancing employee hiring and retention by, among other things, improving the alignment of management and employee incentives with performance and growth objectives of our business.

We may not achieve the anticipated benefits of being a standalone public company for a variety of reasons, and it could adversely affect our operating results and financial condition.

The services that we receive from our Founders may not be sufficient for us to operate our business, and we would likely incur significant incremental costs if we lost access to our Founders’ services.

Because we have not operated as an independent company, we have obtained, and will need to continue to obtain, services from our Founders relating to many important corporate functions including the support we receive from AES relating to clean energy project development and the access Siemens provides to its global sales channels, among various others. We will pay our Founders mutually agreed-upon fees for these services, which will be based on their costs of providing the services.

If we lost access to the services provided to us by certain of our Founders, we would need to replicate or replace certain functions, systems, and infrastructure. We may also need to make investments or hire additional employees to operate without the same access to our Founders’ existing operational infrastructure and wide-ranging support. These initiatives may be costly to implement. Due to the scope and complexity of the underlying projects relative to these efforts, the amount of total costs could be materially higher than our estimate, and the timing of the incurrence of these costs could be subject to change.

TABLE OF CONTENTS

We may not be able to replace these services or enter into appropriate third-party agreements on terms and conditions, including cost, comparable to those that we have received in the past and will continue to receive from our Founders. Additionally, if the agreements pursuant to which such services are provided are terminated, we may be unable to sustain the services at the same levels or obtain the same benefits as when we were receiving such services and benefits from our Founders. If we have to operate these functions separately, if we do not have our own adequate systems and business functions in place or if we are unable to obtain them from other providers, we may not be able to operate our business effectively or at comparable costs, and our profitability may decline. In addition, we have historically received informal support from certain of our Founders. The level of this informal support could diminish or be eliminated following this offering.

While we are controlled by our Continuing Equity Owners, we may not have the leverage to negotiate amendments to our agreements with our Founders, if required, on terms as favorable to us as those we would negotiate with an unaffiliated third party.

Our historical financial results are not necessarily representative of the results we have or may achieve as a standalone company and may not be a reliable indicator of our future results.

Our historical financial results included in this prospectus do not reflect the financial condition, results of operations or cash flows we would have achieved as a standalone company during the periods presented or those we will achieve in the future. This is primarily the result of the following factors:

•

our historical financial results reflect charges for the use of certain proprietary and third-party intellectual property licensed or sublicensed from certain of our Founders under a prior intercompany intellectual property license agreement;

•

our cost of potential future debt and our capital structure will be different from that reflected in our historical financial statements;

•

we will incur additional ongoing costs as a result of this offering, including costs related to public company reporting, investor relations, and compliance with the Sarbanes-Oxley Act; and

•

this offering may have a material effect on our relationship with our players and our other business relationships, including supplier relationships.

Our financial condition and future results of operations could be materially different from amounts reflected in our historical financial statements included elsewhere in this prospectus, so it may be difficult for investors to compare our future results to historical results or to evaluate our relative performance or trends in our business.

Similarly, the pro forma financial information included in this prospectus includes adjustments based upon available information we believe to be reasonable. However, the assumptions may change and actual results may differ. In addition, we have not made pro forma adjustments to reflect changes that will occur in our cost structure, funding, and operations as a result of our transition to becoming a public company, including any changes that may occur in our employee base, potential increased costs associated with reduced economies of scale and increased costs associated with being a publicly traded, standalone company.

Risks Related to Our Organizational Structure

Our principal asset after the completion of this offering will be our interest in Fluence Energy, LLC, and, as a result, we will depend on distributions from Fluence Energy, LLC to pay our taxes and expenses, including payments under the Tax Receivable Agreement. Fluence Energy, LLC’s ability to make such distributions may be subject to various limitations and restrictions.

Upon the consummation of this offering and the Transactions, we will be a holding company and will have no material assets other than our ownership of LLC Interests. As such, we will have no independent means of generating revenue or cash flow, and our ability to pay our taxes and operating expenses or declare and pay dividends in the future, if any, will be dependent upon the financial results and cash flows of Fluence Energy, LLC and its subsidiaries and distributions we receive from Fluence Energy, LLC. There can be no assurance that Fluence Energy, LLC and its subsidiaries will generate sufficient cash flow to

TABLE OF CONTENTS

distribute funds to us or that applicable state law and contractual restrictions, including negative covenants in our debt instruments, will permit such distributions. Although Fluence Energy, LLC is not currently subject to any debt instruments or other agreements that would restrict its ability to make distributions to us, our future debt agreements, including our Revolver, may restrict the ability of our subsidiaries to pay dividends to Fluence Energy, LLC.

Fluence Energy, LLC will continue to be treated as a partnership for U.S. federal income tax purposes and, as such, generally will not be subject to any entity-level U.S. federal income tax. Instead, any taxable income of Fluence Energy, LLC will be allocated to holders of LLC Interests, including us. Accordingly, we will incur income taxes on our allocable share of any net taxable income of Fluence Energy, LLC. Following this offering, we expect to use distributions from Fluence Energy, LLC to fund any payments that we will be required to make under the Tax Receivable Agreement. Under the terms of the Fluence Energy LLC Agreement, Fluence Energy, LLC will be obligated, subject to various limitations and restrictions, including with respect to our debt agreements, to make tax distributions to holders of LLC Interests, including us, although tax distributions may not be paid in whole or in part in certain circumstances, including if Fluence Energy, LLC does not have available cash to make such distributions. In addition to tax expenses, we will also incur expenses related to our operations, including payments under the Tax Receivable Agreement, which we expect could be significant. See “Certain Relationships and Related Party Transactions—Tax Receivable Agreement.” We intend, as its managing member, to cause Fluence Energy, LLC to make cash distributions to the holders of LLC Interests in an amount sufficient to (1) fund all or part of their tax obligations in respect of taxable income allocated to them and (2) cover our operating expenses, including payments under the Tax Receivable Agreement. However, Fluence Energy, LLC’s ability to make such distributions may be subject to various limitations and restrictions, such as restrictions on distributions that would either violate any contract or agreement to which Fluence Energy, LLC is then a party, including debt agreements, or any applicable law, or that would have the effect of rendering Fluence Energy, LLC insolvent. If we do not have sufficient funds to pay tax or other liabilities, or to fund our operations (including, if applicable, as a result of an acceleration of our obligations under the Tax Receivable Agreement), we may have to borrow funds, which could materially and adversely affect our liquidity and financial condition, and subject us to various restrictions imposed by any lenders of such funds. To the extent we are unable to make timely payments under the Tax Receivable Agreement for any reason, such payments generally will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement resulting in the acceleration of payments due under the Tax Receivable Agreement. See “Certain Relationships and Related Party Transactions—Tax Receivable Agreement” and “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement.” In addition, if Fluence Energy, LLC does not have sufficient funds to make distributions, our ability to declare and pay cash dividends will also be restricted or impaired. See “—Risks related to the offering and ownership of our Class A common stock” and “Dividend Policy.”

As a result of (1) potential differences in the amount of net taxable income allocable to us and to Fluence Energy, LLC’s other equityholders, (2) the lower tax rate applicable to corporations as opposed to individuals, and (3) certain tax benefits that we anticipate from (a) future redemptions or exchanges of LLC Interests from the Founders, (b) payments under the Tax Receivable Agreement and (c) certain other transactions, tax distributions to us may be in amounts that exceed our tax liabilities. Our board of directors will determine the appropriate uses for any excess cash so accumulated, which may include, among other uses, the payment of obligations under the Tax Receivable Agreement. We will have no obligation to distribute such cash (or other available cash) to our stockholders. No adjustments to the redemption or exchange ratio or price for LLC Interests and corresponding shares of Class B-1 or Class B-2 common stock will be made as a result of any cash distribution by us or any retention of cash by us. To the extent we do not distribute such excess cash as dividends on our Class A common stock, we may take other actions with respect to such excess cash, for example, holding such excess cash, or lending it (or a portion thereof) to Fluence Energy, LLC or its subsidiaries, which may result in shares of our Class A common stock increasing in value relative to the value of LLC Interests. The holders of LLC Interests may benefit from any value attributable to such cash balances or loan receivables if they acquire shares of Class A common stock in exchange for their LLC Interests or otherwise exercise their rights to redeem or exchange their LLC Interests, notwithstanding that such holders may have participated previously as holders of LLC Interests in distributions by Fluence Energy, LLC that resulted in the excess cash balances.

TABLE OF CONTENTS

The Tax Receivable Agreement with the Founders requires us to make cash payments to them in respect of certain tax benefits to which we may become entitled, and we expect that such payments will be substantial.

In connection with the consummation of this offering, we will enter into a Tax Receivable Agreement with Fluence Energy, LLC and the Founders. Under the Tax Receivable Agreement, we will be required to make cash payments to such Founders equal to 85% of the tax benefits, if any, that we actually realize, or in certain circumstances are deemed to realize, as a result of (1) the increases in our share of the tax basis of assets of Fluence Energy, LLC and its subsidiaries resulting from any future redemptions or exchanges of LLC Interests from the Founders as described under “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement” and certain distributions (or deemed distributions) by Fluence Energy, LLC; and (2) certain other tax benefits arising from payments under the Tax Receivable Agreement. We anticipate funding ordinary course payments under the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under any future debt agreements. We expect that the amount of the cash payments we will be required to make under the Tax Receivable Agreement will be substantial. Based on certain assumptions described in “Unaudited Pro Forma Consolidated Financial Information”, we estimate our Founders will be entitled to receive payments under the Tax Receivable Agreement (assuming all Founders exchange their LLC Interests for shares of Class A common stock on the date of this offering) totaling approximately $487.2 million. Any payments made by us to the Founders under the Tax Receivable Agreement will not be available for reinvestment in our business and will generally reduce the amount of overall cash flow that might have otherwise been available to us and have a substantial negative impact on our liquidity. To the extent that we are unable to make timely payments under the Tax Receivable Agreement for any reason, the unpaid amounts generally will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement resulting in the acceleration of payments due under the Tax Receivable Agreement. The payments under the Tax Receivable Agreement are not conditioned upon continued ownership of us by the redeeming or exchanging Founders. Furthermore, our future obligation to make payments under the Tax Receivable Agreement could make us a less attractive target for an acquisition, particularly in the case of an acquirer that cannot use some or all of the tax benefits that are the subject of the Tax Receivable Agreement. For more information, see “Certain Relationships and Related Party Transactions—Tax Receivable Agreement.” The actual increase in tax basis, and the actual utilization of any resulting tax benefits, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors: including the timing of redemptions of exchanges by the Founders; the price of shares of our Class A common stock at the time of the exchange; the extent to which such redemptions or exchanges are taxable; the amount of gain recognized by such Founders; the amount and timing of the taxable income allocated to us or otherwise generated by us in the future; the portion of our payments under the Tax Receivable Agreement constituting imputed interest; and the federal and state tax rates then applicable.

Our organizational structure, including the Tax Receivable Agreement, confers certain benefits upon the Founders that will not benefit holders of our Class A common stock to the same extent that it will benefit the Founders.

Our organizational structure, including the Tax Receivable Agreement, confers certain benefits upon the Founders that will not benefit the holders of our Class A common stock to the same extent that it will benefit such Founders. We will enter into the Tax Receivable Agreement with Fluence Energy, LLC and certain Founders in connection with the completion of this offering and the Transactions, which will provide for the payment by us to such Founders of 85% of the amount of tax benefits, if any, that we actually realize, or in some circumstances are deemed to realize, as a result of (1) the increases in our share of the tax basis of assets of Fluence Energy, LLC and its subsidiaries resulting from any future redemptions or exchanges of LLC Interests from the Founders as described under “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement” and certain distributions (or deemed distributions) by Fluence Energy, LLC and (2) certain other tax benefits arising from payments under the Tax Receivable Agreement. See “Certain Relationships and Related Party Transactions—Tax Receivable Agreement.” Although we will retain 15% of the amount of such tax benefits, this and other aspects of our organizational structure may adversely impact the future trading market for the Class A common stock.

TABLE OF CONTENTS

In certain cases, payments under the Tax Receivable Agreement may be accelerated or significantly exceed any actual benefits we realize in respect of the tax attributes subject to the Tax Receivable Agreement.

The Tax Receivable Agreement will provide that if (1) we materially breach any of our material obligations under the Tax Receivable Agreement and the Continuing Equity Owners elect an early termination of the Tax Receivable Agreement, (2) certain mergers, asset sales, other forms of business combinations or other changes of control were to occur after the consummation of this offering and the Continuing Equity Owners elect an early termination of the Tax Receivable Agreement, or (3) we elect, at any time, an early termination of the Tax Receivable Agreement, then our obligations, or our successor’s obligations, under the Tax Receivable Agreement to make payments would be based on certain assumptions, including an assumption that we would have sufficient taxable income to fully utilize all potential future tax benefits that are subject to the Tax Receivable Agreement.

As a result of the foregoing, we would be required to make an immediate cash payment equal to the present value of the anticipated future tax benefits that are the subject of the Tax Receivable Agreement, based on certain assumptions, which payment may be made significantly in advance of the actual realization, if any, of such future tax benefits. We could also be required to make cash payments to the Founders that are greater than the specified percentage of any actual benefits we ultimately realize in respect of the tax benefits that are subject to the Tax Receivable Agreement. In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring, or preventing certain mergers, asset sales, other forms of business combinations or other changes of control. There can be no assurance that we will be able to fund or finance our obligations under the Tax Receivable Agreement. To the extent we are unable to make timely payments under the Tax Receivable Agreement for any reason, such payments generally will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement resulting in the acceleration of payments due under the Tax Receivable Agreement. We may need to incur debt to finance payments under the Tax Receivable Agreement to the extent our cash resources are insufficient to meet our obligations under the Tax Receivable Agreement as a result of timing discrepancies or otherwise.

We will not be reimbursed for any payments made under the Tax Receivable Agreement in the event that any tax benefits are disallowed.

Payments under the Tax Receivable Agreement will be based on the tax reporting positions that we determine, and the U.S. Internal Revenue Service, or the IRS, or another tax authority, may challenge all or part of the tax basis increases or other tax benefits we claim, as well as other related tax positions we take, and a court could sustain such challenge. If the outcome of any audit of us or our subsidiaries is reasonably expected to adversely affect the rights and obligations of the Continuing Equity Owners under the Tax Receivable Agreement in a material respect, then we will notify the Continuing Equity Owners of such audit, keep them reasonably informed with respect thereto, provide them with a reasonable opportunity to provide information and other input concerning the audit or the relevant portion thereof and consider such information and other input in good faith. The interests of such Founders in any such challenge may differ from or conflict with our interests and your interests, and the Founders may exercise their rights relating to any such challenge in a manner adverse to our interests and your interests. We will not be reimbursed for any cash payments previously made under the Tax Receivable Agreement in the event that any tax benefits initially claimed by us and for which payment has been made are subsequently challenged by a taxing authority and are ultimately disallowed. Instead, any excess cash payments made by us will be netted against any future cash payments we might otherwise be required to make to the applicable Founder under the terms of the Tax Receivable Agreement. However, we might not determine that we have effectively made an excess cash payment to a Founder for a number of years following the initial time of such payment and, if any of our tax reporting positions are challenged by a taxing authority, we will not be permitted to reduce any future cash payments under the Tax Receivable Agreement until any such challenge is finally settled or determined. Moreover, the excess cash payments we made previously under the Tax Receivable Agreement could be greater than the amount of future cash payments against which we would otherwise be permitted to net such excess. The applicable U.S. federal income tax rules for determining applicable tax benefits we may claim are complex and factual in nature, and there can be no assurance that the IRS or a court will not disagree with our tax reporting positions. As a result, payments could be made

TABLE OF CONTENTS

under the Tax Receivable Agreement significantly in excess of any actual cash tax savings that we realize in respect of the tax attributes that are the subject of the Tax Receivable Agreement.

Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our results of operations and financial condition.

We are subject to taxes by the U.S. federal, state, local, and foreign tax authorities. Our future effective tax rates could be subject to volatility or adversely affected by a number of factors, including:

•

allocation of expenses to and among different jurisdictions;

•

changes in the valuation of our deferred tax assets and liabilities;

•

expected timing and amount of the release of any tax valuation allowances;

•

tax effects of stock-based compensation;

•

costs related to intercompany restructurings;

•

changes in tax laws, tax treaties, regulations or interpretations thereof; or

•

lower than anticipated future earnings in jurisdictions where we have lower statutory tax rates and higher than anticipated future earnings in jurisdictions where we have higher statutory tax rates.

In addition, we may be subject to audits of our income, sales and other taxes by U.S. federal, state, and local, and foreign taxing authorities. Outcomes from these audits could have an adverse effect on our operating results and financial condition.

If we were deemed to be an investment company under the Investment Company Act of 1940, as amended, or the 1940 Act, including as a result of our ownership of Fluence Energy, LLC, applicable restrictions could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business.

Under Sections 3(a)(1)(A) and (C) of the 1940 Act, a company generally will be deemed to be an “investment company” for purposes of the 1940 Act if (1) it is, or holds itself out as being, engaged primarily, or proposes to engage primarily, in the business of investing, reinvesting or trading in securities, or (2) it engages, or proposes to engage, in the business of investing, reinvesting, owning, holding or trading in securities and it owns or proposes to acquire investment securities having a value exceeding 40% of the value of its total assets (exclusive of U.S. government securities and cash items) on an unconsolidated basis. We do not believe that we are an “investment company,” as such term is defined in either of those sections of the 1940 Act.

We and Fluence Energy, LLC intend to conduct our operations so that we will not be deemed an investment company. As the sole managing member of Fluence Energy, LLC, we will control and operate Fluence Energy, LLC. On that basis, we believe that our interest in Fluence Energy, LLC is not an “investment security” as that term is used in the 1940 Act. However, if we were to cease participation in the management of Fluence Energy, LLC, or if Fluence Energy, LLC itself becomes an investment company, our interest in Fluence Energy, LLC could be deemed an “investment security” for purposes of the 1940 Act.

We and Fluence Energy, LLC intend to conduct our operations so that we will not be deemed an investment company. If it were established that we were an unregistered investment company, there would be a risk that we would be subject to monetary penalties and injunctive relief in an action brought by the SEC, that we would be unable to enforce contracts with third parties and that third parties could seek to obtain rescission of transactions undertaken during the period it was established that we were an unregistered investment company. If we were required to register as an investment company, restrictions imposed by the 1940 Act, including limitations on our capital structure and our ability to transact with affiliates, could make it impractical for us to continue our business as contemplated and could have a material adverse effect on our business.

TABLE OF CONTENTS

General Risk Factors

We will incur significant costs as a result of operating as a public company.

Prior to this offering, we operated on a private basis. After this offering, we will be subject to the reporting requirements of the Exchange Act, the Sarbanes-Oxley Act, the Dodd-Frank Act, the listing requirements of the exchange on which our securities are listed and other applicable securities laws and regulations. The expenses incurred by public companies generally for reporting and corporate governance purposes have been increasing. We expect these rules and regulations to increase our legal and financial compliance costs and to make some activities more difficult, time-consuming, and costly, although we are currently unable to estimate these costs with any degree of certainty. We also expect that being a public company and being subject to new rules and regulations will make it more expensive for us to obtain director and officer liability insurance, and we may be required to accept reduced coverage or incur substantially higher costs to obtain coverage. These laws and regulations could also make it more difficult for us to attract and retain qualified persons to serve on our board of directors, our board committees or as our executive officers. Furthermore, if we are unable to satisfy our obligations as a public company, we could be subject to delisting of our Class A common stock, fines, sanctions, and other regulatory action and potentially civil litigation. These factors may, therefore, strain our resources, divert management’s attention, and affect our ability to attract and retain qualified board members.

As a result of becoming a public company following our IPO, we will be obligated to develop and maintain proper and effective internal control over financial reporting in order to comply with Section 404 of the Sarbanes-Oxley Act. We may not complete our analysis of our internal control over financial reporting in a timely manner, or these internal controls may not be determined to be effective, which may adversely affect investor confidence in us and, as a result, the value of our common stock. In addition, because of our status as an emerging growth company, you will not be able to depend on any attestation from our independent registered public accountants as to our internal control over financial reporting for the foreseeable future.

We will become a public company following our IPO, and we will be required by Section 404 of the Sarbanes-Oxley Act to furnish a report by management on, among other things, the effectiveness of our internal control over financial reporting as of the year ending September 30, 2022. The process of designing and implementing internal control over financial reporting required to comply with this requirement will be time-consuming, costly, and complicated. If during the evaluation and testing process we identify one or more other material weaknesses in our internal control over financial reporting or determine that existing material weaknesses have not been remediated, our management will be unable to assert that our internal control over financial reporting is effective. In addition, if we fail to achieve and maintain the adequacy of our internal controls, as such standards are modified, supplemented, or amended from time to time, we may not be able to ensure that we can conclude on an ongoing basis that we have effective internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act.

Even if our management concludes that our internal control over financial reporting is effective, our independent registered public accounting firm may issue a report that is qualified if it is not satisfied with our controls or the level at which our controls are documented, designed, operated, or reviewed. However, our independent registered public accounting firm will not be required to attest formally to the effectiveness of our internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act until the later of the filing of our second annual report following the completion of our IPO or the date we are no longer an “emerging growth company,” as defined in the JOBS Act. Accordingly, you will not be able to depend on any attestation concerning our internal control over financial reporting from our independent registered public accountants for the foreseeable future.

During the fiscal year ended September 30, 2020, a material weakness in the internal control over revenue recognition process has been identified. The design and implementation of controls has not been sufficient to adequately interpret ASC 606 in the design of the accounting policy related to in-transit and delivered, but uninstalled equipment. We are in the process of developing a remediation plan which includes, without limitation, i) hiring additional experienced accounting, financial reporting and internal control personnel as we transition to being a public company and are required to comply with Section 404 of the Sarbanes-Oxley Act, ii) implementing controls to enhance our review of significant accounting transactions

TABLE OF CONTENTS

and other new technical accounting and financial reporting issues and preparing and reviewing accounting memoranda addressing these issues, and iii) implementing controls to enable an effective and timely review of account analyses and account reconciliations. We have recently hired additional resources, and we are engaging with a third-party consulting firm to assist us with our formal internal control plan and provide staff augmentation of our internal audit function.

The material weaknesses will not be considered remediated until management designs and implements effective controls that operate for a sufficient period of time and management has concluded, through testing, that these controls are effective.

We and our independent registered public accounting firm were not required to, and did not, perform an evaluation of our internal control over financial reporting as of September 30, 2020, in accordance with Section 404(b) of the Sarbanes-Oxley Act. Accordingly, we cannot assure you that we have identified all, or that we will not in the future have additional, material weaknesses. Material weaknesses may still exist when we report on the effectiveness of our internal control over financial reporting as required under Section 404 of the Sarbanes-Oxley Act.

We cannot be certain as to the timing of completion of our evaluation, testing, and any remediation actions or the impact of the same on our operations. If we are not able to implement the requirements of Section 404 of the Sarbanes-Oxley Act in a timely manner or with adequate compliance, our independent registered public accounting firm may issue an adverse opinion due to ineffective internal controls over financial reporting, and we may be subject to sanctions or investigation by regulatory authorities, such as the SEC. As a result, there could be a negative reaction in the financial markets due to a loss of confidence in the reliability of our financial statements. In addition, we may be required to incur costs in improving our internal control system and the hiring of additional personnel. Any such action could negatively affect our results of operations and cash flows.

Our management team has limited experience managing a public company.

Most members of our management team have limited experience managing a publicly traded company, interacting with public company investors, and complying with the increasingly complex laws pertaining to public companies. Our management team may not successfully or efficiently manage us as a public company that is subject to significant regulatory oversight and reporting obligations under the federal securities laws and the continuous scrutiny of securities analysts and investors. These new obligations and constituents require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could adversely affect our business, results of operations and financial condition. See “—We will incur significant costs as a result of operating as a public company.”

Future litigation or administrative proceedings could have a material adverse effect on our business, financial condition, and results of operations.

We have been and continue to be involved in legal proceedings, administrative proceedings, claims, and other litigation. In addition, since our energy storage product is a new type of product in a nascent market, we have in the past needed and may in the future need to seek the amendment of existing regulations or, in some cases, the creation of new regulations, in order to operate our business in some jurisdictions. Such regulatory processes may require public hearings concerning our business, which could expose us to subsequent litigation. Unfavorable outcomes or developments relating to proceedings to which we are a party or transactions involving our products and services, such as judgments for monetary damages, injunctions, or denial or revocation of permits, could have a material adverse effect on our business, financial condition, and results of operations. In addition, settlement of claims could adversely affect our financial condition and results of operations.

OUR ORGANIZATIONAL STRUCTURE

Fluence Energy, Inc., a Delaware corporation, was formed on June 21, 2021 and is the issuer of the Class A common stock offered by this prospectus. Prior to this offering and the Transactions (as defined below), all of our business operations have been conducted through Fluence Energy, LLC and its direct and indirect subsidiaries and the Original LLC Owners are the only owners of Fluence Energy, LLC. We will consummate the Transactions, excluding this offering, prior to the consummation of this offering.

Existing Organization

Fluence Energy, LLC is treated as a partnership for U.S. federal income tax purposes and, as such is generally not subject to any U.S. federal entity-level income taxes. Taxable income or loss of Fluence Energy, LLC is included in the U.S. federal income tax returns of Fluence Energy, LLC’s members. Prior to the consummation of this offering, the Original LLC Owners were the only members of Fluence Energy, LLC.

Transactions

Prior to the Transactions, we expect there will initially be one holder of common stock of Fluence Energy, Inc. We will consummate the following organizational transactions in connection with this offering:

This approach provides the Founders with the tax treatment of continuing to own interests in a pass-through structure and provides potential future tax benefits for both Fluence Energy, Inc. and the Founders when the Founders ultimately redeem their LLC Interests for shares of Class A common stock or cash from the sale of newly issued shares of Class A common stock. One of the tax benefits to the Founders associated with this structure is that the portion of Fluence Energy, LLC’s future taxable income that is allocated to the Founders will be taxed for U.S. federal income tax purposes on a flow-through basis and therefore will not be subject to corporate income taxes for such purposes at the Fluence Energy, LLC level. Additionally, because the Founders will be entitled to have their LLC Interests redeemed for newly issued shares of our Class A common stock on a one-for-one basis or, at our option, for cash from the sale of newly issued shares of Class A common stock, the Up-C structure also provides the Founders with potential liquidity that holders of non-publicly traded limited liability companies are not typically afforded.

Fluence Energy, Inc. also expects to benefit from the Up-C structure, in general, in the form of cash tax savings in amounts equal to 15% of certain tax benefits that Fluence Energy, Inc. actually realizes (or in some circumstances is deemed to have realized) arising from Basis Adjustments (as defined below) and certain other tax benefits related to our entering into the Tax Receivable Agreement, including tax benefits attributable to payments under the Tax Receivable Agreement. Such cash tax benefits and cash tax savings generally would not be available to Fluence Energy, Inc. without the Up-C structure. The Tax Receivable Agreement is discussed in “Certain Relationships and Related Party Transactions—Tax Receivable Agreement,” and the estimated payments with respect thereto are set forth in “—The Offering—Tax receivable agreement.” See “Risk Factors—Risks Related to Our Company and Our Organizational Structure.”

This diagram excludes shares of Class A common stock reserved for issuance under options issued pursuant to the Existing Equity Plan which will convert upon effectiveness of this offering into options to acquire shares of Class A common stock, phantom units issued pursuant to the Existing Phantom Equity Plan, which will convert into a right to receive cash or equity based upon the value of shares of Class A common stock, or shares of Class A common stock reserved for issuance under our 2021 Equity Plan.

As the sole managing member of Fluence Energy, LLC, we will operate and control all the business and affairs of Fluence Energy, LLC and, through Fluence Energy, LLC and its direct and indirect

subsidiaries, conduct our business. Following the Transactions, including this offering, Fluence Energy, Inc. will control the management of Fluence Energy, LLC as its sole managing member. As a result, Fluence Energy, Inc. will consolidate Fluence Energy, LLC and record a significant non-controlling interest in a consolidated entity in Fluence Energy, Inc.’s consolidated financial statements for the economic interest in Fluence Energy, LLC held by the Founders.

Incorporation of Fluence Energy, Inc.

Fluence Energy, Inc., the issuer of the Class A common stock offered by this prospectus, was incorporated as a Delaware corporation on June 21, 2021. Fluence Energy, Inc. has not engaged in any business transactions or activities to date and had no assets or liabilities during the periods presented in this prospectus, and will not engage in any activities prior to consummation of this offering except in connection with its formation and the Transactions. The amended and restated certificate of incorporation of Fluence Energy, Inc. that will become effective immediately prior to the consummation of this offering will, among other things, authorize three classes of common stock, Class A common stock, Class B-1 common stock and Class B-2 common stock, each having the terms described in “Description of Capital Stock.”

Reclassification and Amendment and Restatement of the Fluence Energy LLC Agreement

Prior to the consummation of this offering, the existing limited liability company agreement of Fluence Energy, LLC will be amended and restated to, among other things, recapitalize its capital structure by creating a single new class of units that we refer to as “common units” and provide for a right of redemption of common units in exchange for, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq), who are disinterested), shares of our Class A common stock or cash from the sale of newly issued shares of Class A common stock. See “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement.”

Tax Receivable Agreement

Prior to the completion of this offering, we will enter into a Tax Receivable Agreement with our Founders that provides for the payment by Fluence Energy, Inc. to such Founders of 85% of the benefits, if any, that Fluence Energy, Inc. actually realizes, or is deemed to realize (calculated using certain assumptions), as a result of (i) increases in Fluence Energy, Inc.’s allocable share of the tax basis of the assets of Fluence Energy, LLC and its subsidiaries resulting from future redemptions or exchanges of LLC Interests by the Founders and (ii) certain other tax benefits related to our entering into the Tax Receivable Agreement, including tax benefits attributable to payments under the Tax Receivable Agreement. Future redemptions or exchanges of LLC Interests are expected to result in increases in the tax basis of the assets of Fluence Energy, LLC and certain of its subsidiaries. The increases in existing tax basis and the tax basis adjustments generated over time may increase (for tax purposes) the depreciation and amortization deductions available to Fluence Energy, Inc. and, therefore, may reduce the amount of U.S. federal, state and local tax that Fluence Energy, Inc. would otherwise be required to pay in the future. Actual tax benefits realized by Fluence Energy, Inc. may differ from tax benefits calculated under the Tax Receivable Agreement as a result of the use of certain assumptions in the Tax Receivable Agreement, including the use of an assumed state and local income tax rate to calculate tax benefits. This payment obligation is an obligation of Fluence Energy, Inc. and not of Fluence Energy, LLC, and is expected to be significant. We anticipate funding ordinary course payments under the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under any future debt agreements. We expect that the amount of the cash payments we will be required to make under the Tax Receivable Agreement will be substantial. We estimate our Founders will be entitled to receive payments under the Tax Receivable Agreement (assuming all Founders exchange their LLC Interests for shares of Class A common stock on the date of this offering) totaling approximately $487.2 million. Any payments made by us to the Founders under the Tax Receivable Agreement will not be available for reinvestment in our business and will generally reduce the amount of overall cash flow that might have otherwise been available to us and have a substantial negative impact on our liquidity. To the extent that we are unable to make timely payments under the Tax Receivable Agreement for any reason, the unpaid amounts generally will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement resulting in the acceleration of payments due under the Tax Receivable Agreement. See “Certain Relationships and Related Person Transactions—Tax Receivable Agreement.”

TABLE OF CONTENTS

USE OF PROCEEDS

We intend to use the net proceeds from this offering to purchase 31,000,000 newly issued LLC Interests (or 35,650,000 LLC Interests if the underwriters exercise in full their option to purchase additional shares of Class A common stock) directly from Fluence Energy, LLC at a price per unit equal to the initial public offering price per share of Class A common stock in this offering less the underwriting discount and estimated offering expenses payable by us.

Fluence Energy, LLC intends to use the net proceeds from the sale of LLC Interests to Fluence Energy, Inc. to repay all outstanding amounts under our existing Line of Credit and the Promissory Notes (as defined below), and the remainder for working capital and other general corporate purposes.

On August 11, 2021, Fluence Energy, LLC entered into a promissory note with each of Siemens Industry (the “Siemens Promissory Note”) and AES Grid Stability, (the “AES Promissory Note” and together with the Siemens Promissory Note, the “Promissory Notes”), under which Fluence Energy, LLC received a bridge financing of an aggregate of $50.0 million. In connection with the bridge financing, Fluence Energy, LLC issued a $25.0 million promissory note to each of Siemens Industry and AES Grid Stability. The Promissory Notes are unsecured, the AES Promissory Note has a maturity date of August 11, 2022 and the Siemens Promissory Note has a maturity date of December 31, 2021. If we complete a private placement or public offering of certain equity securities prior to the maturity date, the Promissory Notes and all accrued interest thereunder will automatically and without notice be due and payable within five business days. The Promissory Notes bear interest at 2.86% per annum through and until the earliest of the maturity date thereunder and or a mandatory prepayment event (including consummation of this offering), at which time the interest rate will increase by an additional 2%. The proceeds from the Promissory Notes are being used by Fluence Energy, LLC to provide additional liquidity and to fund ongoing working capital needs.

Assuming no exercise of the underwriters’ option to purchase additional shares of Class A common stock, each $1.00 increase (decrease) in the assumed initial public offering price of $22.50 per share (which is the midpoint of the estimated price range set forth on the cover page of this prospectus) would increase (decrease) the net proceeds to us from this offering by approximately $29.4 million and, in turn, the net proceeds received by Fluence Energy, LLC from the sale of LLC Interests to Fluence Energy, Inc. by $29.4 million, assuming the number of shares offered, as set forth on the cover page of this prospectus, remains the same, and after deducting the underwriting discount and estimated offering expenses payable by us.

Each 1,000,000 share increase (decrease) in the number of shares offered by us in this offering would increase (decrease) the net proceeds to us from this offering by approximately $21.3 million and, in turn, the net proceeds received by Fluence Energy, LLC from the sale of LLC Interests to Fluence Energy, Inc. by $21.3 million, assuming that the price per share for the offering remains at $22.50 (which is the midpoint of the estimated price range set forth on the cover page of this prospectus), and after deducting the underwriting discount and estimated offering expenses payable by us.

Fluence Energy, LLC will bear or reimburse Fluence Energy, Inc. for all of the expenses incurred in connection with the Transactions, including this offering.

TABLE OF CONTENTS

DIVIDEND POLICY

We currently intend to retain all available funds and any future earnings to fund the development and growth of our business, and therefore we do not anticipate declaring or paying any cash dividends on our Class A common stock in the foreseeable future. Holders of our Class B-1 and Class B-2 common stock are not entitled to participate in any dividends declared by our board of directors. Furthermore, because we are a holding company, our ability to pay cash dividends on our Class A common stock depends on our receipt of cash distributions from Fluence Energy, LLC and, through Fluence Energy, LLC, cash distributions and dividends from our other direct and indirect subsidiaries. Assuming Fluence Energy, LLC makes distributions out of earnings and profits (other than tax distributions and other distributions to pay expenses) to its members in any given year, we currently expect, subject to the determination of our board of directors, to pay dividends on our Class A common stock out of the portion of such distributions remaining after our payment of taxes, Tax Receivable Agreement payments and expenses, and subject to Delaware law. Our ability to pay dividends may be restricted by the terms of any future credit agreement or any future debt or preferred equity securities of us or our subsidiaries. See “Description of Capital Stock” and “Management’s Discussion and Analysis of Financial Condition and Results of Operation—Liquidity and Capital Resources.” Any future determination as to the declaration and payment of dividends, if any, will be at the discretion of our board of directors and subject to compliance with contractual restrictions and covenants in the agreements governing our future indebtedness. Any such determination will also depend upon our business prospects, results of operations, financial condition, cash requirements and availability and other factors that our board of directors may deem relevant.

Accordingly, you may need to sell your shares of our Class A common stock to realize a return on your investment, and you may not be able to sell your shares at or above the price you paid for them. See “Risk Factors—Risks related to the offering and ownership of our Class A common stock—Because we have no current plans to pay regular cash dividends on our Class A common stock following this offering, you may not receive any return on investment unless you sell your Class A common stock for a price greater than that which you paid for it.”

Immediately following this offering, we will be a holding company, and our principal asset will be the LLC Interests we purchase from Fluence Energy, LLC and acquire indirectly from the Blocker Shareholder. If we decide to pay a dividend in the future, we may need to cause Fluence Energy, LLC to make distributions to us in an amount sufficient to cover such dividend. If Fluence Energy, LLC makes such distributions to us, the other holders of LLC Interests will be entitled to receive pro rata distributions, although tax distributions that Fluence Energy, LLC makes may not be pro rata. See “Risk Factors—Risks related to our organizational structure—Our principal asset after the completion of this offering will be our interest in Fluence Energy, LLC, and, as a result, we will depend on distributions from Fluence Energy, LLC to pay our taxes and expenses, including payments under the Tax Receivable Agreement. Fluence Energy, LLC’s ability to make such distributions may be subject to various limitations and restrictions.”

TABLE OF CONTENTS

DILUTION

The Founders will own LLC Interests after the Transactions, and the Blocker Shareholder will receive shares of Class A common stock in the Transactions. We have presented dilution in pro forma net tangible book value per share both before and after this offering assuming that all of the holders of LLC Interests (other than Fluence Energy, Inc.) had their LLC Interests redeemed or exchanged for newly issued shares of Class A common stock on a one-for-one basis (rather than for cash) and the automatic transfer to the Company and cancellation for no consideration of all of their shares of Class B-1 and Class B-2 common stock (which are not entitled to receive distributions or dividends, whether cash or stock from Fluence Energy, Inc.) in order to more meaningfully present the dilutive impact on the investors in this offering. We refer to the assumed redemption or exchange of all LLC Interests for shares of Class A common stock as described in the previous sentence as the Assumed Redemption.

Dilution is the amount by which the offering price paid by the purchasers of the Class A common stock in this offering exceeds the pro forma net tangible book value per share of Class A common stock after the offering. Fluence Energy, LLC’s pro forma net tangible book value as of June 30, 2021 prior to this offering and after giving effect to the other Transactions and the Assumed Redemption was a deficit of $15.3 million. Pro forma net tangible book value per share prior to this offering is determined by subtracting our total liabilities from the total book value of our tangible assets and dividing the difference by the number of shares of Class A common stock deemed to be outstanding after giving effect to the Assumed Redemption.

If you invest in our Class A common stock in this offering, your ownership interest will be immediately diluted to the extent of the difference between the initial public offering price per share and the pro forma net tangible book value per share of our Class A common stock after this offering.

Pro forma net tangible book value per share after this offering is determined by subtracting our total liabilities from the total book value of our tangible assets and dividing the difference by the number of shares of Class A common stock deemed to be outstanding, after giving effect to the Transactions, including this offering and the application of the net proceeds from this offering as described in “Use of Proceeds,” and the Assumed Redemption. Our pro forma net tangible book value as of June 30, 2021, after giving effect to this offering would have been approximately $616.1 million, or $3.69 per share of Class A common stock. This amount represents an immediate increase in pro forma net tangible book value of $3.58 per share to our existing stockholders and an immediate dilution in pro forma net tangible book value of approximately $18.92 per share to new investors purchasing shares of Class A common stock in this offering. We determine dilution by subtracting the pro forma net tangible book value per share after this offering from the amount of cash that a new investor paid for a share of Class A common stock. The following table illustrates this dilution:

The following table illustrates this dilution on a per share basis to new investors.

Assumed initial public offering price per share of common stock			$22.50
Pro forma net tangible book value per share as of June 30, 2021	$	(0.11)
Increase per share attributable to new investors purchasing shares of common stock in this offering		3.69
Pro forma as adjusted net tangible book value per share immediately after this offering					3.58
Dilution in pro forma as adjusted net tangible book value per share to new common stock investors in this offering				$	18.92

The following table summarizes, as of June 30, 2021, after giving effect to the Transactions (including this offering) and the Assumed Redemption, the number of shares of Class A common stock purchased from us, the total consideration paid, or to be paid, to us and the average price per share paid, or to be paid, by existing owners and by the new investors. The calculation below is based on an assumed initial public offering price of $22.50 per share, which is the midpoint of the estimated price range set forth on the cover page of this prospectus, before deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

TABLE OF CONTENTS

	Shares Purchased				Total Consideration					Average price per Share
	Number		Percent		Amount			Percent		Average price per Share
Existing stockholders		135,666,665		81.4%		$	223,424,000		24.3%		$	1.65
New investors		31,000,000		18.6			697,500,000		75.7		$	22.50
Total		166,666,665		100%		$	920,924,000		100%

Each $1.00 increase (decrease) in the assumed initial public offering price of $22.50 per share would increase (decrease) the total consideration paid by new investors and the total consideration paid by all stockholders by $29.4, assuming the number of shares offered by us and the selling stockholder, as set forth on the cover page of this prospectus, remains the same and after deducting the underwriting discounts and commissions but before estimated offering expenses.

The number of shares of our Class A common stock outstanding after this offering as shown in the tables above is based on the number of shares outstanding as of September 30, 2021, after giving effect to the Transactions and the Assumed Redemption. The discussion and tables above exclude shares of Class B-1 and Class B-2 common stock, because holders of the Class B-1 and Class B-2 common stock are not entitled to distributions or dividends, whether cash or stock, from Fluence Energy, Inc. To the extent that options are issued under our compensatory stock plans or we issue additional shares of common stock in the future, there will be further dilution to investors participating in this offering.

Except as otherwise indicated, the discussion and the tables above assume no exercise of the underwriters’ option to purchase additional shares of Class A common stock. If the underwriters exercise in full their option to purchase additional shares of Class A common stock, the percentage of shares of Class A common stock held by the Continuing Equity Owners will decrease to approximately 34.2% of the total number of shares of our Class A common stock outstanding after this offering; and the number of shares held by new investors will increase to 35,650,000, or approximately 65.8% of the total number of shares of our Class A common stock outstanding after this offering.

UNAUDITED PRO FORMA CONSOLIDATED FINANCIAL INFORMATION

Fluence Energy, Inc. was formed on June 21, 2021 and does not have historical financial results. Fluence Energy, Inc. currently has no assets or liabilities and has conducted no operations. The following unaudited pro forma consolidated financial information reflects the impact of this offering, after giving effect to the Transactions discussed in “Our Organizational Structure.” Following the completion of the Transactions, Fluence Energy, Inc. will be a holding company whose principal asset will consist of 29.7% of the outstanding LLC Interests that it acquires directly from Fluence Energy, LLC and indirectly from the Blocker Shareholder in connection with this offering. The remaining LLC Interests will be held by the Founders. Fluence Energy, Inc. will act as the sole managing member of Fluence Energy, LLC. Fluence Energy, Inc. will operate and control the business and affairs of Fluence Energy, LLC and its direct and indirect subsidiaries, and, through Fluence Energy, LLC and its direct and indirect subsidiaries, conduct its business.

The following unaudited pro forma consolidated statements of operations for the year ended September 30, 2020 and the nine months ended June 30, 2021 give effect to the Transactions, including this offering, as if the same had occurred on October 1, 2019. The unaudited pro forma consolidated balance sheet as of June 30, 2021 presents our unaudited pro forma balance sheet giving effect to the Transactions, including this offering, as if they had occurred as of June 30, 2021.

We have derived the unaudited pro forma consolidated statement of operations and unaudited pro forma consolidated balance sheet from the consolidated financial statements of Fluence Energy, LLC and its subsidiaries included elsewhere in this prospectus. The unaudited consolidated pro forma financial information has been prepared on the basis that we will be taxed as a corporation for U.S. federal and state income tax purposes and, accordingly, will become a taxpaying entity subject to U.S. federal, state and foreign income taxes. The presentation of the unaudited consolidated pro forma financial information is prepared in conformity with Article 11 of Regulation S-X, as amended by the final rule, Release 33-10786 “Amendments to Financial Disclosures about Acquired and Disposed Businesses.” The unaudited consolidated pro forma financial information has been adjusted to include Transaction Accounting Adjustments, which reflect the application of the accounting required by generally accepted accounting principles in the United States (“GAAP”), linking the effects of the transactions listed above to the Company’s historical consolidated financial statements and is based on currently available information and certain estimates and assumptions. See the accompanying notes to the unaudited consolidated pro forma financial information for a discussion of assumptions made.

We refer to the adjustments related to the Transactions, including the impact of the Transactions described in “Our Organizational Structure,” but excluding the adjustments related to the Offering, as the Pro Forma Transaction Adjustments.

The adjustments related to this offering, which we refer to as the Pro Forma Offering Adjustments, are described in the notes to the unaudited pro forma consolidated financial information and principally include the following:

•

the amendment and restatement of the limited liability company agreement of Fluence Energy, LLC to, among other things, appoint Fluence Energy, Inc. as the sole managing member of Fluence Energy, LLC and provide certain redemption rights to the Founders;

•

the issuance of 18,493,275 shares of our Class A common stock to the Blocker Shareholder in one or more mergers, pursuant to which we acquire their LLC Interests;

•

the execution of the Tax Receivable Agreement and recognition of the related payable under such agreement;

•

the issuance of 31,000,000 shares of our Class A common stock to the investors in this offering in exchange for net proceeds of approximately $660.9 million (based on an assumed initial public offering price of $22.50 per share, the midpoint of the estimated price range set forth on the cover page of this prospectus), after deducting the underwriting discounts and commissions but before estimated offering expenses payable by us; and

TABLE OF CONTENTS

•

the payment of fees and expenses related to this offering and the application of the net proceeds from the sale of Class A common stock in this offering to purchase LLC Interests from Fluence Energy LLC and certain Continuing Equity Owners at a purchase price per unit equal to the initial public offering price per share of Class A common stock less the underwriting discounts and commissions, with such LLC Interests representing 29.7% of the outstanding LLC Interests.

Except as otherwise indicated, the unaudited pro forma consolidated financial information presented assumes no exercise by the underwriters of their option to purchase additional shares of Class A common stock in the offering.

As a public company, we will be implementing additional procedures and processes for the purpose of addressing the standards and requirements applicable to public companies. We expect to incur additional annual expenses related to these additional procedures and processes and, among other things, additional directors’ and officers’ liability insurance, director fees, additional expenses associated with complying with the reporting requirements of the SEC, transfer agent fees, costs relating to additional accounting, legal and administrative personnel, increased auditing, tax and legal fees, stock exchange listing fees and other public company expenses. We have not included any pro forma adjustments relating to these costs in the information below.

The unaudited pro forma consolidated financial information is included for informational purposes only. The unaudited pro forma consolidated financial information should not be relied upon as being indicative of our results of operations or financial condition had the Transactions, including this offering, occurred on the dates assumed. The unaudited pro forma consolidated financial information also does not project our results of operations or financial position for any future period or date. The unaudited pro forma consolidated statement of operations and balance sheet should be read in conjunction with the “Risk Factors,” “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our consolidated financial statements and related notes included elsewhere in this prospectus.

We expect to obtain an increase in the tax basis of our share of the assets of Fluence Energy, LLC and certain of its subsidiaries when common units are redeemed or exchanged by the Founders if the value of the common units redeemed or exchanged exceeds the existing tax basis of the corresponding share of the assets of Fluence Energy, LLC at the time of the redemption or exchange, and in other qualifying transactions. This increase in tax basis may have the effect of reducing the amounts that we would otherwise pay in the future to various tax authorities. The increase in tax basis may also decrease gains (or increase losses) on future dispositions of certain capital assets to the extent tax basis is allocated to those capital assets. In connection with the consummation of this offering, we will enter into a Tax Receivable Agreement with AES Grid Stability and Siemens Industry that will provide for the payment by us to AES Grid Stability and Siemens Industry of 85% of the amount of tax benefits, if any, that we actually realize or in some cases are deemed to realize as a result of certain increases in the tax basis of assets of Fluence Energy, LLC and its subsidiaries resulting from, redemptions or exchanges (or deemed exchanges) of LLC Interests or certain distributions (or deemed distributions) by Fluence Energy, LLC and (ii) certain additional tax benefits related to our entering into the Tax Receivable Agreement, including tax benefits attributable to payments that we make under the Tax Receivable Agreement. See “Related Party Transactions—Tax Receivable Agreement.”

If all of the Founders were to exchange or redeem their LLC Interests for Class A common stock pursuant to the terms of the Fluence Energy LLC Agreement, we would recognize a deferred tax asset of approximately $811.0 million and a related liability for payments under the Tax Receivable Agreement of approximately $487.2 million, assuming, among other factors, (i) all exchanges occurred on the same day; (ii) a price of $22.50 per share of Class A common stock (the midpoint of the estimated price range set forth on the cover of this prospectus); (iii) a constant corporate tax rate of 27%; (iv) we will have sufficient taxable income to fully utilize the tax benefits; (v) Fluence Energy, LLC is able to fully depreciate or amortize its assets; and (vi) no material changes in applicable tax law. These amounts are estimates and have been prepared for informational purposes only. The actual amount of deferred tax assets and related liabilities that we will recognize will differ based on, among other things, the timing of the redemptions or exchanges, the price of our shares of Class A common stock at the time of the redemptions or exchanges and the tax rates then in effect.

Notes to unaudited pro forma consolidated balance sheet

(1)

Fluence Energy, Inc. was formed on June 21, 2021 and will have no material assets or results of operations until the consummation of the Transactions, and therefore its historical financial position is not shown in a separate column in this unaudited pro forma balance sheet.

(2)

In connection with this offering the Class B membership units will be recapitalized and converted into Class A common stock of Fluence Energy, Inc. As a result, no Class B membership units will be outstanding following the offering.

(3)

As a result of the Transactions, we will hold a significant equity interest in Fluence Energy, LLC. and will be the managing member of Fluence Energy, LLC. Accordingly, we will operate and control all of the business and affairs of Fluence Energy, LLC and, through Fluence Energy, LLC. and its operating subsidiaries, conduct Fluence Energy, Inc.’s business. As a result, we will consolidate the financial results of Fluence Energy, LLC and will report a non-controlling interest related to the LLC Units held by the Continuing Equity Owners on our consolidated balance sheet.

The computation of the non-controlling interest following the consummation of this offering, based on the assumed initial public offering price, is as follows:

	Units		Percentage
Interest in Fluence Energy, LLC held by Fluence Energy, Inc.		49,493,275		29.7%
Non-controlling interest in Fluence Energy, LLC held by Continuing Equity Owners		117,173,390		70.3%

TABLE OF CONTENTS

In connection with this offering, we will issue 117,173,390 shares of Class B-1 common stock to the Continuing Equity Owners, on a one to-one basis with the number of common units of Fluence Energy, LLC they own for nominal consideration.

The following table includes a reconciliation of the impact of this adjustment to non-controlling interest:

(4)

Reflects the net effect on cash of the receipt of offering proceeds to us of $650.9, based on the assumed sale of shares of Class A common stock at an assumed initial public offering of $22.50 per share, the midpoint of the estimated price range set forth on the cover page of this prospectus, after deducting the underwriting discounts and commissions and estimated offering expenses payable by us. These amounts, as described in “Use of Proceeds,” will be used by Fluence Energy, LLC to repay any future outstanding borrowings under our existing Line of Credit and the Promissory Notes, and the remainder for working capital and other general corporate purposes.

(5)

This adjustment relates to: (a) the cumulative catch-up for the services provided under both the Options and Phantoms of $15.1 million, (b) a modification of historical grants to the former CEO, (c) a modification of historical grants to executives of the Company, and (d) a Day 1 liability related to the liability classified awards of $11.2 million, all of which we expect to incur following the completion of this offering. Below is a further breakdown of the four components, respectively:

(a) Options and Phantom awards which meet their performance condition upon the IPO and are adjusted based on their original grant date fair value representing a cumulative adjustment of the service to-date on outstanding awards since grant; and

(b) Immediately prior to this offering, the existing Options and Phantoms will be modified, qualifying as an improbable to improbable modification under ASC 718, to remove their required service condition and change their performance condition settlement to be paid in cash at the time of IPO. The $4.8 million charge represents the value of the Options and Phantoms as of the new measurement date;

(c) Immediately prior to this offering, the existing Phantom awards for executive members of the Company will be modified, qualifying as an improbable to improbable modification under ASC 718, to extend their required service condition after the performance condition has been met. The $13.3 million charge represents the value of the Phantoms as of the new measurement date which is based on the assumed initial public offering price of $22.50 per share, the midpoint of the estimated price range set forth on the cover page of this prospectus; and

(d) Options and Phantom awards which are liability classified and will be cash settled at an assumed initial public offering of $22.50 per share, the midpoint of the estimated price range set forth on the cover page of this prospectus, after deducting the underwriting discounts and commissions but before estimated offering expenses payable by us.

(6)

We are deferring certain costs associated with this offering, including certain legal, accounting, and other related expenses, which have been recorded in other assets on our consolidated balance sheet. Upon completion of this offering, these deferred costs will be charged against the proceeds from this offering with a corresponding reduction to additional paid-in capital.

This adjustment relates to the compensation expense we expect to incur following the completion of

TABLE OF CONTENTS

this offering which relates to stock compensation expense related to the 827,590 option awards and 145,330 phantom units granted in April 2021 and outstanding as of June 30, 2021.These awards were subject to performance conditions, including a liquidity event such as an IPO. Accordingly, in connection with the IPO, the Company expects to record an accelerated charge of $13.1 million as explained in Note 5 (refer to Balance Sheet) related to the cumulative catch-up for the service provided and the modification of awards granted to the former CEO that will be settled in cash. The Company has calculated $33.9 million for the fiscal year 2020 annual period and $7.6 million for the nine months ended June 30, 2021 interim period using a graded vesting approach, which front loads the compensation expense over the service vesting term, causing a majority of the expense to be recognized in fiscal year 2020 assuming the awards had been granted on October 1, 2019.

(3)

Following the Transactions, we will be subject to United States federal income taxes, in addition to applicable state and local taxes, with respect to our allocable share of any net taxable income of Fluence Energy, LLC. Fluence Energy, LLC has been, and will continue to be, treated as a partnership for U.S. federal and state income tax purposes. As such, income generated by Fluence Energy, LLC will flow through to its partners, including us, and is generally not subject to tax at the Fluence Energy, LLC level. Given the historical losses of Fluence Energy, LLC, the deferred tax assets carry a full valuation allowance, and as such, the effective tax rate following the consummation of this offering is expected to be 3.5%. We will continue to assess the realizability of the deferred tax assets each reporting period.

(4)

Upon completion of the Transactions, we will become the sole managing member of Fluence Energy, LLC. We will have the sole voting interest in, and control of the management of, Fluence Energy, LLC. As a result, we will consolidate the financial results of Fluence Energy, LLC and will report a non-controlling interest related to the interests in Fluence Energy, LLC held by the Founders on our consolidated balance sheet. Immediately following the Transactions, the economic interests held by the non-controlling interest will be approximately 70.3%. If the underwriters exercise their option to purchase additional shares of our Class A common stock in full, the economic interests held by the non-controlling interest will be approximately 68.4%. The impact of all adjustments to the Statement of Operations has been allocated between Fluence Energy, Inc. and non-controlling interests.

(5)

This adjustment relates to amortization of the customary upfront fees paid in connection with the Revolver plus associated legal expenses. The upfront fees and associated legal expenses of $2.0 million are amortized over the four year term of the Revolver. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Liquidity and Capital Resources—Revolving Credit Facility.”

(6)

Pro forma basic earnings per share is computed by dividing the net income available to Class A common stockholders by the weighted- average number of shares of Class A common stock outstanding during the period. Pro forma diluted earnings per share is computed by adjusting the net income available to Class A common stockholders and the weighted-average shares of Class A common stock outstanding to give effect to potentially dilutive securities. Shares of our Class B-1 and Class B-2 common stock are not entitled to receive any distributions or dividends and have no rights to convert into Class A common stock. When a common unit is exchanged for, at the holder’s election, cash or Class A common stock by a Founder who holds shares of our Class B-1 or Class B-2 common stock, such Founder will be required to surrender a share of Class B-1 common stock or Class B-2 common stock, as the case may be, which we will cancel for no consideration. Therefore, we did not include shares of our Class B-1 or Class B-2 common stock in the computation of pro forma basic earnings per share. As we have incurred losses for all periods presented, pro forma diluted loss per share is equal to pro forma basic loss per share because the effect of potentially dilutive securities would be antidilutive.

MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION
AND RESULTS OF OPERATIONS

The following discussion and analysis should be read in conjunction with our audited consolidated financial statements and related notes as of and for the fiscal years ended September 30, 2020 and 2019, as well as our unaudited condensed consolidated financial statements and the related notes as of and for the nine months ended June 30, 2021 and 2020 appearing elsewhere in this prospectus. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth under “Risk Factors” or in other parts of this prospectus.

Historically, our business has been operated through Fluence Energy, LLC, together with its subsidiaries. Fluence Energy, Inc. was formed for the purpose of this offering and has engaged to date only in activities in contemplation of this offering. Upon the completion of this offering, all of our business will continue to be conducted through Fluence Energy, LLC, together with its subsidiaries, and the financial results of Fluence Energy, LLC will be consolidated in our financial statements. Fluence Energy, Inc. will be a holding company whose sole material asset will be the LLC Interests in Fluence Energy LLC. Fluence Energy LLC is, and will continue to be, taxed as a partnership for federal income tax purposes and, as a result, its members, including Fluence Energy, Inc. will pay income taxes with respect to their allocable shares of its net taxable income. For more information regarding the organizational transactions and holding company structure, see “Our Organizational Structure.” As of June 30, 2021, Fluence Energy, LLC had three subsidiaries: Fluence Energy GmbH in Germany, Fluence Energy Pty Ltd. in Australia, and Fluence Energy Inc. in the Philippines.

Our fiscal year begins on October 1 and ends on September 30.

Overview

We are enabling the global clean energy transition with market-leading energy storage products and services and digital applications for renewables and storage. We believe energy storage is at the center of this transition and is becoming even more important as more renewables are added to the grid and the transportation sector moves towards electrification. We are driving change by delivering configurable energy storage product, service, and digital application packages, as well as our AI-enabled Fluence IQ Platform to optimize renewable and third-party storage assets. Our offerings help major utilities, developers, and C&I customers around the world to deliver a more sustainable, reliable, and resilient electric grid in a repeatable, scalable way.

Fluence Energy, LLC was established in January 2018 as a joint venture between AES Grid Stability and Siemens Industry. On December 27, 2020, we entered into a subscription agreement with QFH for the issuance of 1,250,000 Class B units for a total value of $125.0 million. Following the completion of the transaction on June 9, 2021, and as of June 30, 2021, AES Grid Stability holds 3,960,000 Class A units, or 43.2% of our limited liability interest, Siemens Industry holds 3,960,000 Class A units, or 43.2% of our limited liability interest and QFH holds 1,250,000 Class B units, or 13.6% of our limited liability interests.

Since our inception in January 2018, we have focused on international growth and to further develop our energy storage product and delivery services, the operational services, and digital applications. We have incurred net operating losses each year since our inception. We have financed our operations with equity contributions from AES Grid Stability, Siemens Industry, and QFH, cash and cash equivalents, negative working capital, and short-term borrowings.

As of June 30, 2021, we deployed cumulative 942 MW of energy storage products, compared to 460 MW as of September 30, 2020. We recognized revenue of $492.6 million, representing an increase of $170.7 million, or 53.0%, for the nine months ended June 30, 2021 compared to the nine months ended June 30, 2020 as we expanded our sales in terms of the number of energy storage products sold as well as geographic footprint in 2021. Revenue generated from operations in the United States increased from $230.6 million in the nine months ended June 30, 2020 to $357.1 million in the nine months ended June 30, 2021, representing a 54.9% increase. Revenue generated from international operations increased from $91.3 million

TABLE OF CONTENTS

in the nine months ended June 30, 2020 to $135.5 million in the nine months ended June 30, 2021, representing a 48.4% increase, which was driven by growth in existing international markets and expansion into new markets.

Revenue and costs of goods and services both increased significantly due to increased sales volumes, while relatively greater weighted average cost of material and supplies, resulted in a decreased gross profit margin for the nine months ended June 30, 2021 compared to the nine months ended June 30, 2020.

Research and development, sales and marketing, and general and administrative expenses all increased for the nine months ended June 30, 2021, compared to the nine months ended June 30, 2020 as we have been investing heavily in our human capital, technology, products and services to support significant increases in our operations and related revenues. We expect these expenses to increase for the foreseeable future as we experience continuing substantial growth and mature as a public company.

We believe the anticipated proceeds of this offering along with cash flows from operations, short-term borrowing, and our June 2021 investment from QIA will be sufficient to meet our expense and capital requirements for the foreseeable future.

Key Factors and Trends

We believe that our performance and future success depend on several factors that present significant opportunities for us but also pose risks and challenges, including those discussed below and in the section of this prospectus titled “Risk Factors.”

Expected Decrease In Lithium-ion Battery Cost

Our revenue growth is directly tied to the continued adoption of energy storage products by our customers. The cost of lithium-ion energy storage hardware has declined significantly in the last decade and has resulted in a large addressable market today. According to BloombergNEF, the component costs for lithium-ion battery packs are expected to fall from $161 per kilowatt hour (“kWh”) in 2020 to $73/kWh in 2030, an 8% annual reduction over this period. The market for energy storage is rapidly evolving, and while we believe costs will continue to decline, there is no guarantee that they will decline or decline at the rates we expect. If costs do not continue to decline, this could adversely affect our ability to increase our revenue or grow our business.

Increasing Deployment Of Renewable Energy

Deployment of renewable energy resources has accelerated over the last decade, and solar and wind have become a low-cost energy source. BloombergNEF estimates that renewable energy is expected to represent 70% of all new global capacity installations over the next 10 years. Energy storage is critical to reducing the intermittency and volatility of solar and wind generation.

Competition

We are a global energy storage leader. We intend to leverage our competitive strengths, technology, leadership, and market share position to help transform the way we power our world for a more sustainable future. The market for our products is competitive, and we may face increased competition as new and existing competitors introduce energy storage solutions and components. Furthermore, as we expand our services and digital applications in the future, we may face other competitors including software providers and some hardware manufacturers that offer software solutions. If our market share declines due to increased competition, our revenue and ability to generate profits in the future may be adversely affected.

Seasonality

We experience seasonality and typically see increased order intake in our third and fourth fiscal quarters (April – September), driven by demand in the Northern Hemisphere to install energy storage products before the summer of the following year. Combined third and fourth fiscal quarter order intake generally accounted for 80% or more of our total intake each year. As a result, revenue generation is typically significantly stronger in our third and fourth fiscal quarters as we provide the majority of our products to

TABLE OF CONTENTS

customers during these periods. Cash flows historically have been negative in our first and second fiscal quarters, neutral to positive in our third fiscal quarter, and positive in our fourth fiscal quarter. See “Recent Developments — Preliminary Fourth Quarter Results.” Our services and digital applications and solutions offerings do not experience the same seasonality given their recurring nature.

Impact of the COVID-19 Pandemic

On March 11, 2020, the World Health Organization declared the outbreak of a strain of novel coronavirus disease, the COVID-19 pandemic, a global pandemic. Governments in affected areas and countries in which we operate have imposed a number of measures designed to contain the outbreak, including business closures, travel restrictions, quarantines, and cancellations of gatherings and events. We have implemented operational and protective measures to ensure the safety, health, and welfare of our employees and stakeholders. This includes implementing work from home policies for all office employees. We have also ensured that all employees and visitors that visit our facilities have access to personal protective equipment, and we strictly enforce social distancing. Many of the sites where our products and services are delivered have been declared critical infrastructure and remained open following the respective safety protocols. However, many of our customers’ project sites have experienced shutdowns and delays related to COVID-19. We will maintain these precautions and procedures until the COVID-19 pandemic is under adequate control. As of June 30, 2021, the COVID-19 pandemic has not had a material impact on our operations or financial condition.

The full impact of the COVID-19 pandemic on our financial condition and results of operations will depend on future developments, such as the ultimate duration and scope of the pandemic, its impact on our employees, customers, and vendors, in addition to how quickly normal economic conditions and operations resume and whether the pandemic impacts other risks disclosed in “Risk Factors” within this prospectus. Even after the pandemic has subsided, we may continue to experience adverse impacts to our business from any economic recession or depression that may occur as a result of the pandemic. Therefore, we cannot reasonably estimate the impact at this time. We continue to actively monitor the pandemic and may decide to take further actions that alter our business operations as may be required by federal, state, or local authorities or that we determine to be in the best interests of our employees, customers, vendors, and shareholders.

Key Components of Our Results of Operations

The following discussion describes certain line items in our Consolidated Statements of Operations.

Total Revenue

We generate revenue from the sale of energy storage products, service agreements with customers to provide operational services related to battery-based energy storage products, and from digital application contracts after the acquisition of AMS in 2021. Fluence enters into contracts with utility companies, developers, and commercial and industrial customers. We derive the majority of our revenues from selling product solutions. When we sell a battery-based energy storage product, we enter into a contract with our customers covering the price, specifications, delivery dates and warranty for the products being purchased, among other things.

Our revenue is affected by changes in the price, volume and mix of products and services purchased by our customers, which is driven by the demand for our products, geographic mix of our customers, strength of competitors’ product offerings, and availability of government incentives to the end-users of our products.

Our revenue growth is dependent on continued growth in the amount of battery-based energy storage products projects constructed each year and our ability to increase our share of demand in the geographies where we currently compete and plan to compete in the future as well as our ability to continue to develop and commercialize new and innovative products that address the changing technology and performance requirements of our customers.

Cost of Goods and Services

Cost of goods and services consists primarily of product costs, including purchased materials and supplies, as well as costs related to shipping, customer support, product warranty and personnel. Personnel

TABLE OF CONTENTS

costs in cost of goods and services includes both direct labor costs as well as costs attributable to any individuals whose activities relate to the transformation of raw materials or component parts into finished goods or the transportation of materials to the customer.

Our product costs are affected by the underlying cost of raw materials, including steel and aluminum supply costs, including inverters, casings, fuses, and cable; technological innovation; economies of scale resulting in lower supply costs; and improvements in production processes and automation. We do not currently hedge against changes in the price of raw materials. We generally expect our average cost of materials and supplies to decrease as sales volumes increase, however, some of these costs, primarily personnel related costs, are not directly affected by sales volume.

Gross Profit (Loss) and Gross Profit Margin

Gross profit (loss) and gross profit margin may vary from quarter to quarter and is primarily affected by our sales volume, product prices, product costs, product mix, customer mix, geographical mix, shipping method, warranty costs, and seasonality.

Operating Expenses

Operating expenses consist of research and development, sales and marketing and general and administrative expenses as well as depreciation and amortization. Personnel-related expenses are the most significant component of our operating expenses and include salaries, benefits, sales commissions, and payroll taxes. We expect to invest in additional resources to support our growth which will increase our operating expenses in the near future.

Research and Development Expenses

Research and development expenses consist primarily of personnel-related expenses, including salaries, benefits, and payroll taxes, for engineers engaged in the design and development of products and technologies, as well as products, materials, and third-party services used in our research and development process. We expect research and development expenses to increase in future periods to support our growth and as we continue to invest in research and development activities that are necessary to achieve our technology and product roadmap goals. These expenses may vary from period to period as a percentage of revenue, depending primarily upon when we choose to make more significant investments.

Sales and Marketing Expenses

Sales and marketing expenses consist primarily of personnel-related expenses, including salaries, benefits, amortization of sales commissions, and payroll taxes, for our sales and marketing organization, consultants and other third-party vendors. We expect to increase our sales and marketing personnel as we expand into new geographic markets. We intend to expand our sales presence and marketing efforts to additional countries in the future.

General and Administrative Expenses

General and administrative expenses consist primarily of personnel-related expenses, including salaries, benefits, and payroll taxes, for our executives, sales, finance, human resources, information technology, engineering and legal organizations that do not relate directly to the sales or research and development functions, as well as travel expenses, facilities costs, bad debt expense and fees for professional services. Professional services consist of audit, legal, tax, insurance, information technology and other costs. We expect general and administrative expenses to increase in the future as we scale our headcount with the growth of our business. We also expect that after the completion of this offering, we will incur additional audit, tax, accounting, legal and other costs related to compliance with applicable securities and other regulations, as well as additional insurance, investor relations and other costs associated with being a public company.

Depreciation and Amortization

Depreciation consists of costs associated with property, plant and equipment (“PP&E”) and amortization of intangibles consisting of patents, licenses, and developed technology over their expected

period of use. We expect that as we increase both our revenues and the number of our general and administrative personnel, we will invest in additional PP&E to support our growth resulting in additional depreciation and amortization.

Tax Expense

As the Company is currently treated as a partnership, we are generally not subject to U.S. federal or state income tax. As such, we do not pay U.S. federal or state income tax, as taxable income or loss will be included in the U.S. tax returns of our members. We are subject to income taxes, including withholding taxes, outside the U.S. and our income tax expense (benefit) on the consolidated statements of operations primarily relates to income taxes from foreign operations, withholding taxes on intercompany royalties and changes in valuation allowances related to deferred tax assets of certain foreign subsidiaries. After consummation of this offering, we will become subject to U.S. federal and state income taxes with respect to our allocable share of any taxable income or loss of Fluence Energy, LLC, and we will be taxed at the prevailing corporate tax rates. We will continue to be subject to foreign income taxes with respect to our foreign subsidiaries and our expectations are valuation allowances will be needed in certain tax jurisdictions. In addition to tax expenses, we also will incur expenses related to our operations, as well as payments under the Tax Receivable Agreement, which we expect could be significant over time. Following this offering, we will receive a portion of any distributions made by Fluence Energy, LLC. Any cash received from such distributions from our subsidiaries will be first used by us to satisfy any tax liability and then to make payments required under the Tax Receivable Agreement.

Other Income, Net

Other income, net consists of income (expense) from foreign currency exchange adjustments for monetary assets and liabilities.

Deployed or Asset Under Management

Deployed represents cumulative energy storage products that have achieved substantial completion and are not decommissioned.

Asset under management for service contracts represents our long-term service contracts with customers associated with our completed energy storage system products. We start providing maintenance, monitoring, or other operational services after the storage product projects are completed.

Asset under management for digital software contracts represents the amount of MWs under signed digital application contracts, including Fluence Trading Platform after the acquisition of AMS in 2021.

Contracted Backlog and Contracted

For our energy storage products contracts, contracted backlog includes signed customer orders or contracts under execution prior to when substantial completion is achieved. For service contracts, contracted backlog includes signed service agreements associated with our storage product projects that have not been completed and the associated service has not started. For digital applications contracts, contracted backlog includes signed agreements where the associated subscription has not started.

Contracted represents new energy storage product contracts, new service contracts and new digital contracts signed during each fiscal year presented.

Pipeline

Pipeline represents our uncontracted, potential revenue from energy storage products, service, and digital software contracts currently in process, which have a reasonable likelihood of contract execution within 24 months. Pipeline is monitored by management to understand the growth of our Company and our estimated future revenue related to customer contracts for our battery-based energy storage products and services.

We cannot guarantee that our contracted backlog or pipeline will result in actual revenue in the originally anticipated period or at all. Contracted backlog and pipeline may not generate margins equal to our historical operating results. We have only recently begun to track our contracted backlog and pipelines on a consistent basis as performance measures, and as a result, we do not have significant experience in determining the level of realization that we will achieve on these contracts. Our customers may experience project delays or cancel orders as a result of external market factors and economic or other factors beyond our control. If our contracted backlog and pipeline fail to result in revenue at all or in a timely manner, we

TABLE OF CONTENTS

could experience a reduction in revenue, profitability, and liquidity. Pipeline is an internal management metric that we construct from market information reported by our global sales force. We monitor and track our pipeline but it is not maintained or audited in accordance with U.S. GAAP.

Non-GAAP Financial Measures

This section contains references to certain non-GAAP financial measures, including Adjusted EBITDA, Adjusted Gross Profit (Loss), Adjusted Gross Profit Margin, Adjusted Net Loss, and Free Cash Flow.

Adjusted Gross Profit (Loss) is calculated using gross profit (loss), adjusted to exclude certain non-recurring income or expenses. Adjusted Gross Profit Margin is calculated using Adjusted Gross Profit (Loss) divided by total revenue.

Adjusted Net Loss is calculated using net loss, adjusted to exclude (i) amortization of intangibles, (ii) equity-based compensation, (iii) other non-recurring income or expenses, and (iv) tax impact of these adjustments.

These non-GAAP measures are intended as supplemental measures of performance and/or liquidity that are neither required by, nor presented in accordance with, GAAP. We present these non-GAAP measures because we believe they assist investors and analysts in comparing our performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our core operating performance. In addition, we use certain of these non-GAAP measures (i) as factors in evaluating management’s performance when determining incentive compensation and (ii) to evaluate the effectiveness of our business strategies.

These non-GAAP measures should not be considered in isolation or as substitutes for performance measures calculated in accordance with GAAP and may not be comparable to similar measures presented by other entities. Readers are cautioned that these non-GAAP measures should not be construed as alternatives to other measures of financial performance calculated in accordance with GAAP. These non-GAAP measures and their reconciliation to GAAP financial measures are shown below.

The following tables present our non-GAAP measures for the periods indicated.

Total Revenue

Total revenue increased from $321.9 million for the nine months ended June 30, 2020 to $492.6 million for the nine months ended June 30, 2021. The increase of $170.7 million, or 53.0%, was mainly from the sales of our battery energy storage products, which increased by $168.8 million, as we expanded our business in the United States and international markets. Sales to customers in the United States and the Philippines increased $126.5 million and $47.5 million, respectively.

Costs of Goods and Services

Cost of goods and services increased from $325.9 million for the nine months ended June 30, 2020 to $502.6 million for the nine months ended June 30, 2021. The $176.7 million or 54.2% increase was primarily from materials and supplies, and shipping costs associated with the sale of our battery energy storage products due to the increased sales volume and higher weighted average cost of the material and supplies. Included within cost of goods and services for the nine months ended June 30, 2021 were $9.8 million in costs related to a cargo loss incident in the period. Refer to Note 12—Commitments and Contingencies.

Gross Profit (Loss) and Gross Profit Margin

Gross loss was $4.1 million and negative gross profit margin was 1.3% for the nine months ended June 30, 2020, compared to gross loss of $10.1 million and negative gross profit margin of 2.0% for the nine months ended June 30, 2021. The decrease was driven by relatively greater weighted average cost of material and supplies, increased shipping cost and the cargo loss incident in the nine-month period ended June 30, 2021 as compared to the nine-month period ended June 30, 2020.

Research and Development Expenses

Research and development expenses increased from $8.5 million for the nine months ended June 30, 2020 to $17.2 million for the nine months ended June 30, 2021. The $8.7 million or 101.9% increase was mainly related to increased salaries and personnel-related costs as we continued to expand our research and development efforts.

TABLE OF CONTENTS

Sales and Marketing Expenses

Sales and marketing expenses increased from $12.3 million for the nine months ended June 30, 2020 to $16.9 million for the nine months ended June 30, 2021. The increase of $4.6 million, or 37.7%, is related to increased personnel-related expenses for our sales and marketing organization, consultants and other third-party vendors, including the increase in sales and marketing expense in global markets.

General and Administrative Expenses

General and administrative expenses increased from $12.7 million for the nine months ended June 30, 2020 to $23.2 million for the nine months ended June 30, 2021. The $10.5 million or 82.5% increase was mainly related to increases in personnel-related expenses including corporate, executive, finance, and other administrative functions, as well as expenses for outside professional services as we have been expanding our personnel headcount rapidly to support our growth.

Depreciation and Amortization

Depreciation and amortization increased from $2.2 million for the nine months ended June 30, 2020 to $3.5 million for the nine months ended June 30, 2021. This increase was from $0.9 million amortization related to intangible assets from the AMS acquisition and $0.4 million depreciation from increased fixed assets.

Other Expense, Net

Other expense, net, increased from $0.1 million for the nine months ended June 30, 2020 to $1.1 million for the nine months ended June 30, 2021. The $1.0 million or 1,040.9% increase was mainly from foreign currency exchange adjustments for monetary assets and liabilities.

Income Tax Expense

Income tax expense decreased from $5.7 million in the nine months ended June 30, 2020 to $2.9 million in the nine months ended June 30, 2021. The effective income tax rate was (14.2)% and (4.0)% for the nine months ended June 30, 2020 and 2021, respectively. The $2.8 million decrease in income tax expense and change in effective tax rate were primarily due to an increase in global pre-tax loss for the nine months ended June 30, 2021. Furthermore, the income tax expense for the nine months ended June 30, 2020 included an increase in the valuation allowance recorded on deferred tax assets.

Net Loss

Net loss increased from $45.6 million in the nine months ended June 30, 2020 to $74.8 million in the nine months ended June 30, 2021. The increase in net loss was mainly due to an increase in gross loss related to our operations which included expenses of $9.8 million related to the cargo loss incident as well as increased expenses in general and administrative expenses, sales and marketing expenses and research and development expenses due to the expansion of our business and the build out of our corporate functions.

Total Revenue

Total revenue increased from $92.2 million in FY 2019 to $561.3 million in FY 2020. The $469.1 million or 509.1% increase was mainly from the sales of our battery energy storage products as we expanded our business in United State and international markets.

Costs of Goods and Services

Cost of goods and services increased from $100.1 million in FY 2019 to $553.4 million in FY 2020. The $453.3 million or 453.0% increase was primarily from materials and supplies associated with the sale of our battery energy storage products due to the increased sales volume net of lower weighted average cost of the material and supplies.

Gross Profit (Loss) and Gross Profit Margin

Gross profit was $7.9 million, and gross profit margin was 1.4%, in FY 2020, compared to a gross loss of $7.9 million, and a negative gross profit margin of 8.6%, in FY 2019. The increase was driven by higher sales of energy storage products, net of lower per unit cost of material and supplies in FY 2020.

Research and Development Expenses

Research and development expenses increased from $9.9 million in FY 2019 to $11.5 million in FY 2020. The $1.6 million or 16.9% increase in FY 2020 compared to FY 2019 was mainly related to increased salaries and personnel-related costs.

Sales and Marketing Expenses

Sales and marketing expenses increased from $15.0 million in FY 2019 to $16.3 million in FY 2020. The increase of $1.3 million, or 8.5%, is related to increased marketing cost to support our revenue growth.

General and Administrative Expenses

General and administrative expenses increased from $13.9 million in FY 2019 to $17.9 million in FY 2020. The $4.0 million or 28.6% increase in FY 2020 as compared with FY 2019 related mainly to

TABLE OF CONTENTS

increases in personnel-related expenses including corporate, executive, finance, and other administrative functions, as well as expenses for outside professional services as we have been expanding our personnel headcount rapidly to support our growth.

Depreciation and Amortization

Depreciation and amortization remained flat from $2.9 million in FY 2019 to $3.0 million in FY 2020.

Other Income, Net

Other income, net decreased from $1.8 million in FY 2019 to $0.5 million in FY 2020. The $1.3 million or 71.6% decrease was mainly from foreign currency exchange adjustments for monetary assets and liabilities.

Income Tax Expense (Benefit)

Income tax expense increased from a $(0.8) million benefit in FY 2019 to a $6.4 million expense in FY 2020. The $7.2 million increase in income tax expense was mainly due to $3.4 million of tax withholdings on intracompany royalties and increase in valuation allowance of our deferred tax asset for foreign subsidiaries.

The effective income tax rate was (15.9) % and 1.6% for FY 2020 and FY 2019, respectively, with the change due to an increase in our international operations.

Net Loss

Net loss decreased from $47.0 million in FY 2019 to $46.7 million in FY 2020. The slight decrease in net loss was mainly due to an increase in gross profit, offset by increased expenses in general and administrative, sales and marketing, and research and development related to supporting expanding operations of the business, and also due to increase in income tax expense.

Liquidity and Capital Resources

Since inception and through June 30, 2021, our principal sources of liquidity were our cash and cash equivalents, short-term borrowing, capital from AES Grid Stability and Siemens Industry, and proceeds from the QFH investment.

We received a $6.3 million capital contribution from Siemens Industry and a $2.5 million capital contribution from AES Grid Stability during the nine months ended June 30, 2021 and 2020, respectively.

Additionally, we procured liquidity from short-term borrowing from banks. We have an Uncommitted Line of Credit Agreement (“Line of Credit’) with Citibank, N.A. (“Citibank”) originally signed on January 29, 2019, which allows us to borrow an amount in aggregate not to exceed $2.0 million, from time to time, until January 29, 2021 (“Expiration Date”). The Line of Credit was further amended to increase the aggregate borrowing amount to $10.0 million, $30.0 million, and $50.0 million on May 13, 2020, August 7, 2020, and December 23, 2020, respectively. The Expiration Date for the Line of Credit was extended to March 31, 2023, on June 2, 2021. We did not have any outstanding short-term borrowings from the Line of Credit as of June 30, 2021, September 30, 2020 and 2019. Subsequent to June 30, 2021, we borrowed an aggregate of $50.0 million under the line of credit, all of which is outstanding as of September 3, 2021.

On December 27, 2020, we entered into a subscription agreement with QFH for the issuance of 1,250,000 Class B units for a total value of $125.0 million. The transaction completed on June 9, 2021 with the proceeds used to accelerate our growth.

On April 28, 2021 and June 3, 2021, we borrowed $25.0 million and $25.0 million, respectively, from AES in the form of one-year promissory notes, each bearing an annual interest at 2.86%. On May 3, 2021, we borrowed $25.0 million from Siemens Industry, in the form of a one-year promissory note with an annual interest rate of 2.86%. The proceeds were used for general working capital needs. As of June 22, 2021, these total $75.0 million in borrowings from AES and Siemens Industry were paid off in full.

TABLE OF CONTENTS

On August 11, 2021, Fluence Energy, LLC entered into a promissory note with each of Siemens Industry and AES Grid Stability, under which Fluence Energy, LLC received a bridge financing of an aggregate of $50.0 million. In connection with the bridge financing, Fluence Energy, LLC issued a $25.0 million promissory note to each of Siemens Industry and AES Grid Stability (together, the “Promissory Notes”). The Promissory Notes are unsecured and the note with AES Grid Stability matures on August 11, 2022 and the note with Siemens Industry matures on December 31, 2021. If we complete a private placement or public offering of certain equity securities prior to the maturity date, the Promissory Notes and all accrued interest thereunder will automatically and without notice be due and payable within five business days. The Promissory Notes bear interest at 2.86% per annum through and until the earliest of the maturity date thereunder and a mandatory prepayment event, at which time the interest rate will increase by an additional 2%. The proceeds from the Promissory Notes are being used by Fluence Energy, LLC to provide additional liquidity and to fund ongoing working capital needs.

We believe that our current cash and cash equivalents, cash flows from operations, short-term borrowing, and recent investments from QIA through QFH, combined with the anticipated proceeds of this offering, will be sufficient to meet our capital expenditure and working capital requirements for the foreseeable future.

After completion of this offering, Fluence Energy, Inc. will be a holding company and will have no material assets other than its ownership of LLC Interests. Fluence Energy, Inc. has no independent means of generating revenue and is dependent upon the financial results and cash flows of Fluence Energy, LLC and its subsidiaries and distributions we receive from Fluence Energy, LLC. Fluence Energy, Inc. intends to cause Fluence Energy, LLC to make distributions and payments to its holders of LLC Interests, including Fluence Energy, Inc. and our Founders, in an amount sufficient to cover all applicable taxes at assumed tax rates, expenses, payments under the Tax Receivable Agreement and dividends, if any, declared by it. Deterioration in the financial condition, earnings or cash flow of Fluence Energy, LLC and its subsidiaries for any reason could limit or impair their ability to pay such distributions. Additionally, the terms of our financing arrangements, including the Revolving Credit Facility (as defined below), contain covenants that may restrict Fluence Energy, LLC and its subsidiaries from paying such distributions, subject to certain exceptions. Further, Fluence Energy, LLC is generally prohibited under Delaware law from making a distribution to a member to the extent that, at the time of the distribution, after giving effect to the distribution, liabilities of Fluence Energy, LLC (with certain exceptions) exceed the fair value of its assets. Subsidiaries of Fluence Energy, LLC are generally subject to similar legal limitations on their ability to make distributions to Fluence Energy, LLC. See “Dividend Policy” and “Risk Factors—Risks Related to Our Organizational Structure—Our principal asset after the completion of this offering will be our interest in Fluence Energy, LLC, and, as a result, we will depend on distributions from Fluence Energy, LLC to pay our taxes and expenses, including payments under the Tax Receivable Agreement. Fluence Energy, LLC’s ability to make such distributions may be subject to various limitations and restrictions.”

Revolving Credit Facility

In connection with this offering, we plan to enter into the Revolver, dated on or about the date of the consummation of this offering, by and among Fluence Energy, LLC, as the borrower, Fluence Energy Inc., as a parent guarantor, the subsidiary guarantors party thereto, the lenders party thereto and JP Morgan Chase Bank, N.A., as administrative agent and collateral agent. The Revolver will be secured by a (i) first priority pledge of the equity securities of Fluence Energy, LLC and its subsidiaries and (ii) first priority security interests in, and mortgages on, substantially all tangible and intangible personal property and material fee-owned real property of Fluence Energy, LLC, the parent guarantor and each subsidiary guarantor party thereto, in each case, subject to customary exceptions and limitations. The effectiveness of the Revolver is conditioned upon the consummation of this offering, however this offering is not contingent upon the effectiveness of the Revolver.

The interest rate will be either (i) the Adjusted LIBOR or Adjusted EURIBO Rate (each as defined in the Revolver) plus 3.0% or (ii) the Alternate Base Rate (as defined in the Revolver) plus 2.0% (subject to customary LIBOR replacement provisions and alternative benchmark rates including customary spread adjustments with respect to borrowings in foreign currency), at the option of Fluence Energy, LLC. Fluence Energy, LLC is required to pay to the lenders a commitment fee of 0.55% per annum on the average daily unused portion of the revolving commitments through maturity, which will be the four-year anniversary of

TABLE OF CONTENTS

the closing date of the Revolver. The Revolver will also provide for up to $200.0 million in letter of credit issuances, which will require customary issuance and administration fees, as well as a fronting fee payable to each issuer thereof and a letter of credit participation fee of 2.75% per annum payable to the lenders.

The Revolver will contain covenants that, among other things, will restrict our ability to incur additional indebtedness; incur liens; sell, transfer, or dispose of property and assets; make investments or acquisitions; make dividends, distributions or other restricted payments; and engage in affiliate transactions. The Revolver will limit our ability to make certain payments, including dividends and distributions on Fluence Energy, LLC’s equity, Fluence Energy, Inc.’s equity and other restricted payments. In addition, we will be required to maintain (i) minimum liquidity and gross revenue requirements, in each case, until consolidated EBITDA reaches a certain specified threshold and we make an election, and (ii) thereafter, a maximum total leverage ratio and a minimum interest coverage ratio. Such covenants will be tested on a quarterly basis.

Tax Receivable Agreement

In connection with the Offering Transactions, we will enter into the tax receivable agreement (the “Tax Receivable Agreement”) with Fluence Energy, LLC and the Founders that will provide for the payment by Fluence Energy, Inc. to the Founders of 85% of the amount of certain tax benefits, if any, that Fluence Energy, Inc. actually realizes, or in some circumstances is deemed to realize, arising from the Basis Adjustments (as defined below) and certain other tax benefits arising from payments made under the Tax Receivable Agreement. Fluence Energy, LLC will have in effect an election under Section 754 of the Code effective for each taxable year in which a redemption or exchange (including deemed exchange) of LLC Interests for Class A common stock or cash occurs or when Fluence Energy, LLC makes (or is deemed to make) certain distributions. These Tax Receivable Agreement payments are not conditioned upon one or more of the Founders maintaining a continued ownership interest in Fluence Energy, LLC. If a Founder transfers LLC Interests but does not assign to the transferee of such units its rights under the Tax Receivable Agreement, such Founder generally will continue to be entitled to receive payments under the Tax Receivable Agreement arising in respect of a subsequent exchange of such LLC Interests. In general, the Founders’ rights under the Tax Receivable Agreement may not be assigned, sold, pledged or otherwise alienated or transferred to any person, other than certain permitted transferees, without our prior written consent (not to be unreasonably withheld) and such person’s becoming a party to the Tax Receivable Agreement and agreeing to succeed to the applicable Founder’s interest therein.

Subsequent redemptions or exchanges of LLC Interests are expected to result in increases in the tax basis of the assets of Fluence Energy, LLC and certain of its subsidiaries. Increases in tax basis and tax basis adjustments generated over time may increase (for tax purposes) the depreciation and amortization deductions available to Fluence Energy, Inc. and, therefore, may reduce the amount of U.S. federal, state and local tax that Fluence Energy, Inc. would otherwise be required to pay in the future, although the IRS may challenge all or part of the validity of that tax basis, and a court could sustain such a challenge. Fluence Energy, Inc.’s allocable share of tax basis and the anticipated tax basis adjustments upon redemptions or exchanges of LLC Interests may also decrease gains (or increase losses) on future dispositions of certain assets to the extent tax basis is allocated to those assets. Actual tax benefits realized by Fluence Energy, Inc. may differ from tax benefits calculated under the Tax Receivable Agreement as a result of the use of certain assumptions in the Tax Receivable Agreement, including the use of an assumed state and local income tax rate to calculate tax benefits. The payment obligation under the Tax Receivable Agreement is an obligation of Fluence Energy, Inc. and not of Fluence Energy, LLC. Following this offering, we expect to use distributions from Fluence Energy, LLC to fund any payments that we will be required to make under the Tax Receivable Agreement. To the extent we are unable to make timely payments under the Tax Receivable Agreement for any reason, such payments generally will be deferred and will accrue interest until paid; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement resulting in the acceleration of payments due under the Tax Receivable Agreement. Fluence Energy, Inc. expects to benefit from the remaining 15% of cash tax benefits, if any, it realizes from such tax benefits. For purposes of the Tax Receivable Agreement, the cash tax benefits will be computed by comparing the actual income tax liability of Fluence Energy, Inc. to the amount of such taxes that Fluence Energy, Inc. would have been required to pay had there been no such tax basis adjustments of the assets of Fluence Energy, LLC or its subsidiaries as a result of redemptions or exchanges and had Fluence Energy, Inc. not entered into the Tax Receivable Agreement. The actual and

TABLE OF CONTENTS

hypothetical tax liabilities determined in the Tax Receivable Agreement will be calculated using the actual U.S. federal income tax rate in effect for the applicable period and an assumed state and local income tax rate (along with the use of certain other assumptions). The term of the Tax Receivable Agreement will continue until all such tax benefits have been utilized or expired, unless Fluence Energy, Inc. exercises its right to terminate the Tax Receivable Agreement early, certain changes of control occur or Fluence Energy, Inc. breaches any of its material obligations under the Tax Receivable Agreement, in which case, all obligations generally (and in the case of such a change of control or such breach, only if the Founders elect) will be accelerated and due as if Fluence Energy, Inc. had exercised its right to terminate the Tax Receivable Agreement. The payment to be made upon an early termination of the Tax Receivable Agreement will generally equal the present value of payments to be made under the Tax Receivable Agreement using certain assumptions. Estimating the amount of payments that may be made under the Tax Receivable Agreement is by its nature imprecise, insofar as the calculation of amounts payable depends on a variety of factors. The tax basis adjustments upon the redemption or exchange of LLC Interests, as well as the amount and timing of any payments under the Tax Receivable Agreement, will vary depending upon a number of factors, including the timing of purchases or exchanges, the price of shares of our Class A common stock at the time of the purchase or exchange, the extent to which such purchases or exchanges do not result in a basis adjustment, the amount of tax attributes, changes in tax rates and the amount and timing of our income.

We expect that as a result of the anticipated tax basis adjustment of the assets of Fluence Energy, LLC and its subsidiaries upon the redemption or exchange of LLC Interests and our possible utilization of certain tax attributes, the payments that we may make under the Tax Receivable Agreement will be substantial. If all of the Founders were to exchange or redeem their LLC Interests for Class A common stock pursuant to the terms of the Fluence Energy LLC Agreement, we estimate our Founders will be entitled to receive payments under the Tax Receivable Agreement totaling approximately $487.2 million; assuming, among other factors, (i) all exchanges occurred on the same day; (ii) a price of $22.50 per share of Class A common stock (the midpoint of the estimated price range set forth on the cover of this prospectus); (iii) a constant corporate tax rate of 27%; (iv) we will have sufficient taxable income to fully utilize the tax benefits; (v) Fluence Energy, LLC is able to fully depreciate or amortize its assets; and (vi) no material changes in applicable tax law. The payments under the Tax Receivable Agreement are not conditioned upon continued ownership of us by the Founders. Although the timing and extent of future payments could vary significantly under the Tax Receivable Agreement for the factors discussed above, we anticipate funding payments from the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under any future debt agreements, and such payments are not anticipated to be dependent upon the availability of proceeds of this offering. See “Certain Relationships and Related Person Transactions—Tax Receivable Agreement.”

Historical Cash Flows – Nine months ended June 30

The following table summarizes our cash flows from operating, investing, and financing activities for the periods presented.

	Nine Months Ended June 30,						YTD 2021 vs. YTD 2020
($ in thousands)	2021			2020			$ Change		% Change
Net cash (used in) operating activities		$	(139,277)		$	(75,865)		(63,412)		(83.6)%
Net cash (used in) provided by investing activities		$	(20,999)		$	18,293		(39,292)		(214.8)%
Net cash provided by financing activities		$	125,729		$	10,500		115,229		1,097.4%

Net cash flows used in operating activities were $139.3 million in the nine months ended June 30, 2021 compared to $75.9 million in the nine months ended June 30, 2020. The decrease in net operating cash flows was mainly due to increased purchases of inventory due to the significant expansion of our business activities, partially offset by increases in accounts payable and accruals.

Net cash flows used in investing activities in the nine months ended June 30, 2021 included $18.0 million cash paid for acquisitions and $3.0 million cash outflows used in purchases of property and equipment. Net cash flows provided by investing activities in the nine months ended June 30, 2020 included $19.0 million cash inflows from the release of bank deposits that were collateralized for outstanding bank guarantees, net of $1.0 million cash outflows used in purchases of property and equipment.

TABLE OF CONTENTS

Cash flows provided by financing activities of $125.7 million for the nine months ended June 30, 2021 included $117.3 million net proceeds from issuance of Class B membership units and $6.3 million capital contribution from Siemens Industry. Cash flows provided by financing activities of $10.5 million for the nine months ended June 30, 2020 included $ 8.0 million borrowing from lines of credit and $2.5 million capital contribution from AES Grid Stability.

Historical Cash Flows – Annual periods ended September 30

The following table summarizes our cash flows from operating, investing, and financing activities for the periods presented.

	Fiscal Year Ended September 30,						FY 2020 vs. FY 2019
($ in thousands)	2020			2019			Change		Change %
Net cash (used in) provided by operating activities		$	(14,016)		$	27,682		(41,698)		(150.6)%
Net cash provided by (used in) investing activities		$	18,220		$	(22,736)		40,956		180.1%
Net cash provided by financing activities		$	2,500		$	10,000		(7,500)		(75.0)%

Net cash flows used in operating activities were $14.0 million in FY 2020 compared to net cash flows provided by operating activities of $27.7 million in FY 2019. The decrease in net operating cash flows was mainly due to increased trade receivables and unbilled receivable balances from increased sales of energy storage products, partially offset by increased accounts payable and accruals.

Net cash flows from investing activities in FY 2020 included $20.0 million of cash inflows from the release of bank deposits that were collateralized for outstanding bank guarantees, net of $1.8 million of cash out flows used in purchases of property and equipment. Net cash flows used in investing activities in FY 2019 included $20.0 million of bank deposits invested and placed as collateral in FY 2019 and $2.7 million of cash out flows used in purchases of property and equipment.

Cash flows provided by financing activities of $2.5 million and $10.0 million were from capital contributions from AES Grid Stability in FY 2020 and FY 2019, respectively.

Credit Support and Reimbursement Agreement

We are party to an Amended and Restated Credit Support and Reimbursement Agreement with AES and Siemens Industry whereby they may, from time to time, agree to furnish credit support to us in the form of direct issuances of credit support to our lenders or other beneficiaries or through their lenders’ provision of letters of credit to backstop our own facilities or obligations. Pursuant to the Credit Support and Reimbursement Agreement, if AES or Siemens Industry agree to provide a particular credit support (which they are permitted to grant or deny in their sole discretion), they are entitled to receipt of a credit support fee and reimbursement for all amounts paid to our lenders or other counterparties, payable upon demand. The Credit Support and Reimbursement Agreement will not provide any credit support from September 30, 2026, provided that either AES or Siemens Industry will be permitted to terminate the agreement upon six months prior notice.

Critical Accounting Policies and Use of Estimates

Our financial statements have been prepared in accordance with GAAP. In the preparation of these financial statements, we consider an accounting judgment, estimate or assumption to be critical when (1) the estimate or assumption is complex in nature or requires a high degree of judgment and (2) the use of different judgments, estimates, and assumptions could have a material impact on the consolidated financial statements. We believe that the accounting policies discussed below are critical to understanding our historical and future performance, as these policies relate to the more significant areas involving management’s judgments and estimates. Refer to Note 2—Summary of Significant Accounting Policies and Estimates for further discussion of our critical accounting policies and estimates.

TABLE OF CONTENTS

Revenue Recognition

We determine our revenue recognition through the following steps: (i) identification of the contract or contracts with a customer, (ii) identification of the performance obligations within the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the performance obligations within the contract, and (v) recognition of revenue as the performance obligation has been satisfied.

As of June 30, 2021, our revenue was generated primarily from sale and battery-based energy storage products, providing operational services related to storage products, and digital application and solutions.

Sale of Energy Storage Products

Fluence enters into contracts with utility companies, developers, and C&I customers to design and build battery-based energy storage products. Each storage product is customized depending on the customer’s energy needs. Customer payments are due upon meeting certain milestones that are consistent with contract-specific phases of a project. We determine the transaction price based on the consideration expected to be received which includes estimates for project execution risks and other variable considerations, including liquidated damages. The transaction price identified is allocated to each distinct performance obligation to deliver a good or service based on the relative standalone selling prices. Generally, our contracts to design and build battery-based storage solutions are determined to have one performance obligation. We believe that the prices negotiated with each individual customer are representative of the stand-alone selling price of the energy storage products.

We recognize revenue over time as a result of the continuous transfer of control of our energy storage products to the customer. This continuous transfer of control to the customer is supported by clauses in the contracts that provide enforceable rights to payment of the transaction price associated with work performed to date, and is for products that do not have an alternative use to us and/or the project is built on the customer’s land that is under the customer’s control.

Revenue from the contracts is recognized using the percentage of completion method based on cost incurred as a percentage of total estimated contract costs. Contract costs include all direct material and labor costs related to contract performance. Pre-contract costs with no future benefit are expensed in the period in which they are incurred. Since the revenue recognition of these contracts depends on estimates, which are assessed continually during the term of the contract, recognized revenues and profit are subject to revisions as the contract progresses to completion. The cumulative effects of revisions of estimated total contract costs and revenues, together with any contract reserves which may be deemed appropriate, are recorded in the period in which the facts and changes in circumstance become known. Due to the uncertainties inherent in the estimation process, it is reasonably possible that these estimates will be revised in a different period. When a loss is forecasted for a contract, the full amount of the anticipated loss is recognized in the period in which it is determined that a loss will occur.

Services

Fluence also enters into long-term service agreements with customers to provide operational services related to purchased battery-based energy storage products. The services include maintenance, monitoring, and other minor services. We account for the services as a single performance obligation as the services are substantially the same and have the same pattern of transfer to the customers. Straight-line revenue recognition method is applied for these types of services. We believe using a time-based method to measure progress is appropriate as the performance obligations are satisfied evenly over time based on the fact that customers receive the services evenly and cost pattern does not change significantly over the service period. Revenue is recognized by dividing the total contact revenue over the service period.

102

TABLE OF CONTENTS

from other services discussed above. Performance obligations of the services are satisfied over time. Percentage of completion revenue recognition method is applied for service type warranties as the cost pattern changes significantly with little to no operating costs incurred in the earlier years and larger costs incurred in later years when augmentation is required to restore the required capacity, for example, adding more batteries or changing some existing modules with declined capacity.

For both products and service contracts where there are multiple performance obligations in a single contract, we allocate the consideration to the various obligations in the contract based on the relative standalone selling price method. Standalone selling prices are estimated based on estimated costs plus margin or using market data for comparable products when estimated costs are not imputable.

Digital Applications and Solutions

In October 2020, Fluence acquired the Advanced Microgrid Solutions (“AMS”) software and digital intelligence platform, which became the Fluence Trading Platform. Contracts involving the Fluence Trading Platform are generally entered into with commercial entities that control utility-scale storage and renewable generation assets. Fluence Trading Platform arrangements consist of a promise to provide access to proprietary cloud-based Software-as-a-Service (“SaaS”) to promote enhanced financial returns on the utility-scale storage and renewable generation assets. The Fluence Trading Platform is a hosted service that delivers automated, market-compliant bids to local electricity market operators. Customers do not receive legal title or ownership of the software as a result of these arrangements. The term for Fluence’s contracts with Trading Platform customers is generally 5 years, which may include certain renewal options to extend the initial contract term or certain termination options to reduce the initial contract term.

The Fluence Trading Platform is technology- and vendor-agnostic (i.e. it can be utilized for wind and solar assets as well as non-Fluence systems). The Fluence Trading Platform is separately identifiable from other promises that Fluence offers to its customers (i.e. it is not highly interrelated or integrated with other solutions). As such, Fluence determined that the Fluence Trading Platform should be accounted for as a separate performance obligation. Revenue from the Fluence Trading Platform includes an integration fee and a monthly subscription fee. We consider the access to the Fluence Trading Platform and related support services in a customer contract to be a series of distinct services which comprise a single performance obligation because they are substantially the same and have the same pattern of transfer. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met.

Internal Control Over Financial Reporting

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements in accordance with GAAP. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of annual or interim financial statements will not be prevented or detected on a timely basis.

During the fiscal year ended September 30, 2020, a material weakness in the internal control over our revenue recognition process was identified. The design and implementation of controls has not been sufficient to adequately interpret ASC 606 in the design of the accounting policy related to in-transit and delivered, but uninstalled equipment. We are in the process of developing a remediation plan which includes, without limitation, (i) hiring additional experienced accounting, financial reporting and internal control personnel as we transition to being a public company and are required to comply with Section 404 of the Sarbanes-Oxley Act, (ii) implementing controls to enhance our review of significant accounting transactions and other new technical accounting and financial reporting issues and preparing and reviewing accounting memoranda addressing these issues, and (iii) implementing controls to enable an effective and timely review of account analyses and account reconciliations. We have recently hired additional resources, and we are engaging with a third-party consulting firm to assist us with our formal internal control plan and provide staff augmentation of our internal audit function.

103

TABLE OF CONTENTS

We and our independent registered public accounting firm were not required to, and did not, perform an evaluation of our internal control over financial reporting as of June 30, 2021, or September 30, 2020, in accordance with Section 404(b) of the Sarbanes-Oxley Act. Accordingly, we cannot assure you that we have identified all, or that we will not in the future have additional, material weaknesses. Material weaknesses may still exist when we report on the effectiveness of our internal control over financial reporting as required under Section 404 of the Sarbanes-Oxley Act.

Quantitative and Qualitative Disclosures About Market Risk

Market risk is the potential loss that may result from market changes associated with our business or with an existing or forecasted financial transactions. We are exposed to various market risks in the ordinary course of our business which are discussed below.

Credit Risk

Credit risk refers to the risk that a counterparty may default on its contractual obligations resulting in a loss to us. Our counterparties for sale of our energy storage products and delivery service are customers including conglomerates, utilities / load-serving entities, independent power producers, developers, and C&I customers in the United States and other countries. A loss of one or more of our significant customers, their inability to perform under their contracts, or their default in payment could harm our business and negatively impact revenue, results of operations, and cash flows. Credit policies have been approved and implemented to govern our portfolio of counterparties with the objective of mitigating credit losses. These policies establish guidelines, controls, and limits to manage credit risk within approved tolerances by mandating an appropriate evaluation of the financial condition of existing and potential counterparties, monitoring agency credit ratings, and by implementing credit practices that limit exposure according to the risk profiles of the counterparties. In addition, customers are required to make milestone payments based on their project’s progress. We may also, at times, require letters of credit, parent guarantees or cash collateral when deemed necessary.

Our overall exposure may be affected positively or negatively by macroeconomic or regulatory changes that impact our counterparties to one extent or another. As of June 30, 2021, the COVID-19 pandemic has not had a material impact on our credit risk exposure to our counterparties. Currently, management does not anticipate a material adverse effect in our financial position or results of operations as a consequence of counterparty non-performance. We continuously monitor the creditworthiness of all our counterparties.

Foreign Currency Risk

Our reporting currency is the U.S. dollar, while certain of our current subsidiaries have other functional currencies, reflecting their principal operating markets. Fluctuations in currency exchange rates between the U.S. dollar and the Euro, the British pound, the Australian dollar, and the Swiss Franc in our current foreign markets could create significant fluctuations in earnings and cash flows. To date, we have not had material exposure to foreign currency fluctuations and have not had material hedging instruments to hedge the foreign currency risks.

Commodity Price Risk

We are subject to risk from fluctuating market prices of certain commodity raw materials that are used in our products. Prices of these raw materials may be affected by supply restrictions, logistics and shipping, and tariffs or other market factors from time to time, and we do not enter into hedging arrangements to mitigate commodity risk. Significant price changes for these raw materials could reduce our operating margins if we are unable to recover such increases from our customers and could harm our business, financial condition, and results of operations.

TABLE OF CONTENTS

Customer Concentration and Emerging Market Exposure Risk

We deliver products and services in developed economies, including the United States, the United Kingdom, Chile, Ireland, Switzerland, Australia, and Germany. We also deliver products and services in the Philippines, which represent 20.9% and 34.1% of revenue the nine months ended June 30, 2021 and FY 2020, respectively. Macroeconomic conditions in developing economies are usually more volatile than in developed economies and entail certain risks and uncertainties. Changes in the United States trade environment, including the imposition of import tariffs, could adversely affect the amount or timing of our revenues, results of operations or cash flows. The interruption of the flow of components and materials from international vendors could disrupt our supply chain, including as a result of the imposition of additional duties, tariffs and other charges on imports and exports.

Emerging Growth Company Status

We are an emerging growth company, as defined under the JOBS Act. The JOBS Act permits an emerging growth company like us to take advantage of an extended transition period to comply with new or revised accounting standards applicable to public companies. We have elected to take advantage of this extended transition period. As a result, the information that we provide to stockholders may be different than the information you may receive from other public companies in which you hold equity.

Energy Storage Market Opportunity

The energy storage market is comprised of three components: energy storage products; services; and digital applications and solutions. Energy storage products encompass the components (including batteries), professional services, and labor required to manufacture, assemble, and install products. Services include the recurring operational and maintenance services that energy storage products require, management services that are provided by third parties when asset owners outsource the operations of their systems, and the provision of ESaaS. Digital applications and solutions include operating systems, applications, such as trading platforms that allow system owners to manage their grid participation, and dynamic capacity services, such as virtual power plants (“VPPs”). These trading platforms and VPPs can be deployed on both energy storage assets and renewable and conventional generation assets.

The energy storage products market is driven by the deployment of new energy storage products globally, and its addressable market is comprised of the annual spend associated with the manufacturing, delivery, and installation of new energy storage products. According to BloombergNEF, global annual energy storage capacity installations, excluding the residential market, grew from 0.6 GW a year in 2015 to 3.8 GW a year in 2020, and are expected to grow to 34.2 GW a year by 2030. We believe most forecasts for the energy storage sector, including BloombergNEF’s, understate the size and market opportunity as forecasts generally only account for spend associated with the physical energy storage asset and do not account for the associated service and digital spend.

The services market is driven by the growth in installed energy storage products globally, and its addressable market is comprised of the recurring annual service spend across the entire fleet of energy storage products, which is continuing to grow through new product installations. According to

114

TABLE OF CONTENTS

BloombergNEF, global installed energy storage capacity, excluding the residential market, grew 57% per annum between 2015 and 2020, and the installed base is expected to grow at a 31% annual growth rate through 2030. BloombergNEF forecasts that global installed energy storage capacity will reach 193.7 GW by 2030, excluding the residential market.

The digital applications and solutions sector is driven by the growth in installed energy storage products and renewable and conventional generation assets, and its addressable market is comprised of the total global installed fleet of energy storage products and renewable and conventional generation assets. The digital applications and solutions economic model is primarily structured as (i) $/kilowatt (“kW”) recurring fixed fees, and in some cases (ii) $/kW performance-based incentive fees both calculated based on the GWs of storage and generation assets on which digital applications and solutions service offerings are deployed. We believe there is an opportunity to not only deploy digital applications and solutions on individual assets but also across entire energy storage fleets and portfolios of generation assets to improve their collective performance and economic output, and to reduce the overall carbon footprint of the electric grid by optimizing the interactions between different asset types.

Key Drivers of Growing Energy Storage Market

We believe there are multiple factors driving continued growth in the energy storage sector including:

•

Heightened grid variability from the increasing prevalence of renewable energy and decarbonized technologies. BloombergNEF forecasts that 1,298 GW of coal and natural gas power plants are expected to be retired globally over the next 10 years and that renewable energy is expected to represent approximately 75% of all new global capacity installations in the same period. Energy storage is a proven replacement for retiring natural gas plants, as evidenced by the AES Alamitos Battery Energy Storage System in Long Beach, California, which uses Fluence technology and was procured specifically to replace a retiring natural gas plant that provided critical peaking capacity for the LA Basin. The accelerating transition from fossil to renewable generation and from conventional to electric vehicles is expected to require significant increases in energy storage capacity to both offset potential grid instability caused by intermittent renewable resources and enable the use of power from renewable generation assets at times when the natural resource is unavailable.

•

Ability to compensate for infrastructure constraints. The existing power grid was not designed to support distributed and renewable generation infrastructure. Growing capacity constraints on transmission lines are forcing grid operators to curtail, or dump, excess renewable energy, limiting the ability to decarbonize the grid. Energy storage assets placed at strategic nodes on transmission networks allow power to be transmitted during times of increased transmission capacity. This reduces congestion, increases use of existing transmission lines, and lowers system operating costs. Additionally, by being able to store renewable power, grid operators can use renewable energy to meet potential power shortfalls that would otherwise be met by traditional sources of energy such as natural gas peaker plants.

•

Expected decrease in battery costs. According to BloombergNEF, the component costs for lithium-ion battery packs are expected to fall from $161/kWh in 2020 to $73/kWh in 2030, which represents an 8% annual reduction over this period. This forecasted reduction in the battery cost is expected to improve the economics of energy storage and support the development of larger energy storage systems. Moreover, the levelized cost of storage (LCOS) of battery storage has decreased from an estimated $324/MWh in 2018 to an estimated $192/MWh in 2020, according to the Lazard Levelized Cost of Storage Analysis. This reduction in cost makes battery storage economically competitive with the gas peakers which are estimated in 2020 to have a levelized cost of energy (LCOE) range of $151/MWh to $198/MWh, according to the Lazard Levelized Cost of Energy Analysis.

•

Corporate and investor support for decarbonization. Over 300 major companies have pledged to source 100% of their energy from renewable energy as part of the RE100 initiative. This trend has driven over 13 GW of corporate power purchase agreements to be signed in the United States in 2020 compared to just 3 GW in 2017, according to BloombergNEF. Additionally, environmental responsibility has also become a priority for investors. In September 2020, Climate Action 100+, an

115

TABLE OF CONTENTS

investor initiative representing 500 global investors collectively managing more than $47 trillion in assets, sent letters to multiple corporations to urge them to set clear goals to pursue net-zero emissions by 2050 or sooner.

•

Favorable government policy initiatives. Governments across the globe have announced policies to support the transition from fossil fuels to low-carbon forms of energy. For example, the United States recently rejoined the Paris Agreement and proposed a tax incentive for standalone energy storage projects as part of President Biden’s American Jobs Plan. Internationally, the European Union has proposed legislation targeting achieving net-zero emissions by 2050, Australia announced a targeted two-thirds reduction in emissions per unit of gross domestic product by 2030, and India pledged to achieve a 33-35% reduction in emissions intensity by 2030.

•

Automated Trading: System-generated complete bid files (with option for customer override) for seamless transmission to market operators and real-time review of market results.

Our Bidding Application is technology-agnostic (it can be applied to wind and solar assets as well as energy storage assets) and vendor-agnostic (it is available to optimize non-Fluence storage products), and is delivered using cloud-based software-as-a-service, avoiding requirements for onsite hardware or software installations. Our pricing strategy is based on a volume-based subscription fee with the ability to start with a smaller scale and increase the number of assets covered by the software as customers build out their fleets, along with the potential for performance-based revenue-sharing structures.

The Fluence Bidding Application analyzes thousands of variables to provide leading price forecasting and optimization using proprietary machine learning algorithms. The resulting market-compliant bids can increase revenue for wind and solar asset owners by up to 10%, and up to 25-30% for energy storage asset owners over a 12-month period compared to manual trading. The Percent of Perfect Foresight (“PoP”) metric helps asset owners evaluate the performance of an algorithmic trading approach by comparing it with the maximum revenue an asset could have attained if it had perfect knowledge of actual market prices (i.e., “perfect foresight”). The Fluence Bidding Application has delivered up to 90% PoP to customers in Australia’s NEM.

To protect the Fluence OS and Fluence IQ, we employ enterprise-class network security, with firewall software monitoring and controlling all local network traffic. Secure, role-based user access is done via a virtual private network (“VPN”) with multi-factor authentication and 256-bit encryption. High-grade, Advanced Encryption Standard 256-bit encryption is used to protect all data in transit from local systems to the VPC. Data in transit takes place over secure, site-to-site VPN tunnels. A secure, logically isolated cloud environment uses restrictive firewall and security group rules to limit connectivity within the VPC. All external access to the cloud is done using VPN with multi-factor authentication.

TABLE OF CONTENTS

producers, developers, conglomerates, and C&I customers. In fiscal 2020, our five largest customers represented approximately 90% of our revenues. As of June 30, 2021, we had a gross global pipeline of 13.3 GWs, and customers in the United States composed the largest portion of our gross global pipeline at 6.5 GWs or 49%, with the United Kingdom following at 1.7 GWs or 13%, and Australia at 0.7 GWs or 5%.

Our Commitment to Responsible Environmental and Ethical Practices

Our mission is to transform the way we power our world for a more sustainable future. We support the clean energy transition by enabling greater adoption of renewable energy and reduced use of thermal generation resources. Our offerings enable more sustainable, reliable, and resilient electric grids in a repeatable, scalable way.

The AES Alamitos Battery Energy Storage System, which uses Fluence technology, exemplifies our commitment to sustainability. Providing 100 MW / 400 MWh of renewable energy storage to reduce California’s reliance on fossil fuels, it represents the first time in the U.S. that an energy storage product was procured as a peak capacity resource instead of natural gas. This system can provide enough energy to cleanly power 22,000 homes during peak conditions.

We plan to report how we oversee and manage environmental, social, and governance (“ESG”) factors material to our business under the sector-specific ESG standards recommended by the Sustainability Accounting Standards Board (the “SASB”), including an annual sustainability report. As part of our plan to provide ESG disclosures pursuant to SASB standards, we will evaluate aligning our internal sustainability goals with certain United Nations Sustainable Development Goals. On an annualized basis, based on MW deployed as of May 2021, we estimate Fluence energy storage products have eliminated 145,000 metric tons of carbon per year that would have otherwise been produced—the equivalent of taking more than 30,000 cars off the road each year.

Our supplier code of conduct is at the core of our compliance expectations, and addresses environmental protection, child labor, conflict minerals, and anti-corruption, among other areas. In addition, we only purchase raw materials and minerals from trusted suppliers. In sourcing cobalt for example, we request that suppliers provide an official cobalt statement disclosing its origin, and we only buy cobalt battery chemistry from suppliers who are part of a sustainable cobalt sourcing initiative. In 2021, our supply chain sustainability coordinator engaged the Carbon Disclosure Project to conduct an audit of our supply chain’s carbon footprint.

In addition, we are committed to implementing responsible environmental and ethical practices in our corporate offices as well as our supply chain. Our offices are internationally certified to ISO 14001, which requires an organization to implement and demonstrate compliance with an effective environmental management system to identify and control the environmental impact of its activities, products, and services; continually improve environmental performance; and implement a systematic approach to setting environmental objectives and targets.

Human Capital Management

We believe our workforce is critical to our success and we strive to create a positive, equitable, and safe work environment. A survey of employees during the pandemic revealed that most people prefer to work remotely rather than in the office, so Fluence has moved to a 75% remote work policy permanently and offers employees a stipend for home office equipment. To create a culture of transparency, we maintain a regular cadence of communications from the executive leadership team to employees, including emails, quarterly all hands meetings, Q&A sessions, and employee resource groups with executive sponsors.

As of May 31, 2021, we had 379 full-time employees. None of our employees in the United States is represented by a labor union. As of May 31, 2021, approximately 64 of our employees in Germany were represented by a works council. We have not experienced any employment-related work stoppages, and we consider relations with our employees to be good.

Our purpose-driven culture has fostered a work environment in which employees feel supported, empowered to develop in their careers, and fulfilled in their work. Initiatives driven by this culture include a partnership with Inova through which we provide free professional and wellness services to employees and

professional development courses made available to all employees. To assess and continually improve employee sentiment, we conduct regular employee surveys soliciting feedback on topics such as work/life balance, working remotely, career development, and mentorship.

Fluence is internationally certified to ISO 9001, a quality management standard that ensures a commitment to customer satisfaction, purpose-driven leadership, and equitable involvement for all employees. Fluence is also internationally certified to ISO 45001, an occupational health and safety standard which requires certain proactive measures to ensure employee safety and reduce workplace risks. Fluence’s corporate headquarters is certified to SA8000, which demonstrates our commitment to the elimination of unethical and discriminatory labor practices, while affirming workers’ rights, livable wages, and treating all people with dignity.

Fluence is committed to fostering a culture of diversity and inclusion that makes our employees feel safe and engaged. We have conducted trainings for hiring managers on how to avoid bias in the interview process, and formed a diversity and inclusion working group to identify and address areas for improvement. Our workforce includes citizens of 38 countries. Women represent 24% of our total workforce and 40% of our key corporate management roles.

Manufacturing

Our manufacturing strategy is designed to meet our key objectives: limit capital-intensive and low value-added activities that can be outsourced to other companies; maintain a capital light business model; minimize labor content where possible; minimize the amount of assembly our customers are required to do at the site; and minimize material movement both from vendors to us and within factories.

Mass manufacturing is a cornerstone of our product delivery approach and a key to driving down product cost and delivering at scale. We aim to create an optimized production organization, develop mass manufacturing capabilities globally through contract manufacturing, and continue to secure partnerships with key battery suppliers. We believe that enhancing our product-focused model and supply chain leverage will support our global growth objectives and result in superior unit economics.

We have entered outsourcing contracts for the assembly and production of our Fluence Cube, which ship directly from our contract manufacturers to job sites or designated warehouses. By using regional contract manufacturers, we can drop ship products directly to our customers’ sites, which improves working capital turnover, quality, and inventory management. The Fluence Cube is currently manufactured in Asia, and we intend to expand manufacturing to sites in North America and Europe. As of July 31, 2021, Fluence has contracted approximately 1.2 GW of our sixth-generation products.

We have developed a global supply chain with an evolving regionally focused operational model with the objective of allowing us to assemble products in proximity to major markets to minimize material movement, working capital investment, and costs of goods sold. Additionally, we believe that the volume of key components we purchase, such as lithium-ion batteries, provides us preferential pricing, terms, and availability from our suppliers, creating a competitive advantage. We recently entered into a technology co-development and supply agreement with Northvolt that expands our battery supply chain into Europe. Pursuant to this agreement, we have a license to develop, manufacture and commercialize an optimized battery subsystem that is significantly more energy dense than today’s standard solutions. The agreement also enables us to deploy as a battery management system that can be integrated with other vendors to extend our value chain, develop battery competencies, and lower total cost of ownership.

Intellectual Property

The success of our business depends, in part, on our ability to maintain and protect our proprietary technologies, information, processes and know-how. We rely primarily on patent, trademark, copyright and trade secret laws, confidentiality agreements and procedures, and other contractual arrangements to protect our technology. Fluence also has a perpetual license (terminable in the event of an uncured material breach) to certain patents and other intellectual property that belong to AES and Siemens, including methods for cooling inverters, overvoltage protections, and transfer of large amounts of data (methodology).

TABLE OF CONTENTS

As of May 31, 2021, we had access to twenty-one patents and forty-eight patent applications filed by AES in the United States and multiple other countries, and five patents and eleven patent applications filed by Siemens in the United States and multiple other countries. In addition, as of May 31, 2021, we owned ninety-seven trademark registrations globally, one patent application pending for examination in the United States, and eleven domain name registrations. Many of our patents relate to product architecture, application algorithms, and renewable resource integration.

We rely on trade secret protection and confidentiality agreements to safeguard our interests with respect to proprietary know-how and software that is not patented and processes for which patents are difficult to enforce. We believe that many elements of our manufacturing processes involve proprietary know-how, technology or data that are not covered by patents or patent applications, including technical processes, test equipment designs, algorithms, and procedures.

We require our customers and business partners to enter into confidentiality agreements before we disclose any sensitive aspects of our technology or business plans.

Seasonality

We experience seasonality and typically see increased order intake in our third and fourth fiscal quarters, driven by demand in the Northern Hemisphere to install energy storage products before the summer of the following year. Combined third and fourth fiscal quarter order intake in fiscal 2019 and 2020 accounted for 80% or more of our total order intake each year. As a result, revenue recognition is typically stronger in our third and fourth fiscal quarters. Cash flows historically have been negative in our first and second fiscal quarters, neutral to positive in our third fiscal quarter, and positive in our fourth fiscal quarter. Our services and digital application offerings do not experience the same seasonality given their recurring nature. See “Recent Developments — Preliminary Fourth Quarter Results.”

Competition

Our products, services, and digital applications are highly specialized and specific to the clean energy industry. The unique expertise required to design these offerings as well as customers’ reluctance to try unproven products has confined the number of firms that produce such products to a relatively small number, particularly in the segments we are targeting. In addition, we are continuously engaging in developing new use cases and opening new market segments, which are often less contested.

Our principal competitors include Tesla and Wartsila, but competition varies by geography, grid service or customer segment. A key differentiator is our ability to identify customer needs and deliver customer-centric products, services, and use cases that can compete in the market either as packages or standalone offerings. We believe we compete favorably based on performance and value-creation, including low total cost of ownership, long-term reliability, varied service options, and convenient and efficient sales and delivery processes. We believe we are the current market leader in our space.

Government Regulation and Compliance

Governments across the globe have announced policies to support the transition from fossil fuels to low-carbon forms of energy. For example, the United States recently rejoined the Paris Agreement, an international climate change agreement among almost 200 nations that calls for countries to set their own greenhouse gas (“GHG”) emissions targets and be transparent about the measures each country will use to achieve these targets, and proposed a tax incentive for standalone energy storage projects as part of President Biden’s American Jobs Plan. Internationally, the European Union has proposed legislation targeting achieving net-zero emissions by 2050, Australia announced a targeted two thirds reduction in the emissions intensity of its economy by 2030, and India pledged to achieve a 33 – 35% reduction in emissions intensity by 2030.

Current and future legislation or regulations that may be adopted to address climate change could make lower GHG-emitting energy sources, such as solar and wind, more desirable than higher GHG-emitting energy sources, such as coal and natural gas. As a result, such climate change regulatory and legislative

126

TABLE OF CONTENTS

initiatives with more stringent limitations on GHG emissions would potentially increase the demand for energy storage products.

There are varying policy frameworks across the United States and abroad designed to support and accelerate adoption of clean and/or reliable distributed generation technologies. These policy initiatives come in the form of tax incentives, cash grants, performance incentives, and/or electric tariffs.

Our energy storage products are currently installed or in delivery in Arizona, California, Colorado, Indiana, Maryland, Massachusetts, New York, New Jersey, North Carolina, Ohio, Pennsylvania, Texas, and West Virginia, each of which has its own enabling policy framework. Some states have utility procurement programs and/or renewable portfolio standards for which our technology is eligible. Many states, including California, Massachusetts, and New York, offer tax exemptions or other customer incentives. These policy provisions are subject to change.

Although we generally are not regulated as a utility, federal, state, and local government statutes and regulations concerning electricity heavily influence the market for our product and services. These statutes and regulations often relate to electricity pricing, net metering, incentives, taxation, competition with utilities and the interconnection of customer-owned electricity generation. In the United States, governments continuously modify these statutes and regulations. Governments, often acting through state utility or public service commissions, change and adopt different rates for commercial (and residential) customers on a regular basis. These changes can have a positive or negative impact on our ability to deliver cost savings to customers for the purchase of electricity.

Several states have an energy storage mandate or policies designed to encourage the adoption of storage. For example, Virginia has a mandate for 3.1 GW of energy storage by 2035, California offers a cash rebate for storage installations through the Self Generation Incentive Program, and Massachusetts and New York offer performance-based financial incentives for storage. Storage installations also are supported in certain states by state public utility commission policies that require utilities to consider alternatives such as storage before they can build new generation. In February 2018, the Federal Energy Regulatory Commission (“FERC”) issued Order 841 directing regional transmission operators and independent system operators to remove barriers to the participation of storage in wholesale electricity markets and to establish rules to help ensure storage resources are compensated for the services they provide. An appeal of Order 841 filed by utility trade associations and other parties challenging the extent of FERC’s jurisdiction over storage resources connected to distribution systems (among other issues) is currently pending before the U.S. Court of Appeals for the D.C. Circuit. In September 2020, the FERC issued Order 2222 opening U.S. wholesale energy markets to aggregations of distributed energy resources like rooftop solar, “behind the meter” batteries and electric vehicles.

Energy storage products require interconnection agreements from the applicable authorities having jurisdiction to operate. In almost all cases, interconnection agreements are standard form agreements that have been pre-approved by the local public utility commission or other regulatory body with jurisdiction over interconnection agreements. As such, no additional regulatory approvals are typically required once interconnection agreements are signed.

Permits and Approvals

Each of our installations or customer installations must be designed, constructed, and operated in compliance with applicable federal, state, and local regulations, codes, standards, guidelines, policies, and laws. To install and operate energy storage products on our platform, we, our customers, or our partners, as applicable, are required to obtain applicable permits and approvals from local authorities having jurisdiction to install energy storage products and to interconnect the products with the local electrical utility.

Government Incentives

The U.S. Congress is considering a variety of proposals for tax incentives that will benefit the energy storage industry, including in the form of tax credits. IRS private letter ruling 201809003 clarified that energy storage is eligible for federal tax credits if charged primarily by qualifying renewable resources. In

127

TABLE OF CONTENTS

December 2020, the U.S. Congress passed a spending bill that includes $35 billion in energy research and development programs, a two-year extension of the Investment Tax Credit (“ITC”) for solar power, a one-year extension of the Production Tax Credit for wind power projects, and an extension through 2025 for offshore wind tax credits. In June 2021, the White House announced that it will look into dramatically expanding U.S. production of lithium batteries, rare earth minerals, and semiconductors, and seek to stimulate demand for domestically manufactured batteries by expanding federal energy storage procurement, expanding the ITC to include stationary energy storage as a standalone resource, and instituting power transmission regulatory reform to support renewable power and stationary energy storage. Also in June, the Senate passed a $250 billion bipartisan technology and manufacturing bill whose provisions included: (i) provide $52 billion to support domestic semiconductor manufacturing; and (ii) authorize $16.9 billion for the Department of Energy from FY22 to FY26 for research and development and energy-related supply chains in key technology areas. Proposals being considered by Congress include: (i) the establishment of an ITC for standalone energy storage (i.e., products not paired with a renewable resource); (ii) extension of the federal solar energy ITC for ten (10) more years, keeping the credit at 30% through 2029; (iii) the consolidation of 44 federal energy tax incentives into three provisions to award credits for clean electricity, lower-emitting transportation fuels and energy efficient offices and homes; and (iv) the allowance of renewable electricity production and investment tax credits to be transferred on a limited basis to any entity involved in a renewable energy project, regardless of whether they have taxable income. There can be no assurance that all or any of the above proposals will be adopted by the U.S. Congress.

Facilities

Our corporate headquarters are in Arlington, Virginia, and consist of approximately 17,000 square feet of office space. We lease our corporate headquarters. We also have offices in Alpharetta, Georgia, San Francisco, California, Erlangen, Germany, Melbourne, Australia, and Taguig City, Philippines. Our Erlangen office includes an energy storage testing facility.

We believe that our existing properties are in good condition and are sufficient and suitable for the conduct of our business for the foreseeable future. To the extent our needs change as our business grows, we expect that additional space and facilities will be available.

We have gone through rigorous certification processes at several of our offices and are actively pursuing additional certification at others. The corporate office space and the testing facility in Erlangen are ISO 9001, ISO 14001, and ISO 45001 certified (quality, environmental and safety certifications, respectively). Our Melbourne office is ISO 9001 certified, and our U.S. Arlington office is SA8000 certified which is a standard of ethical and decent working conditions.

Legal Proceedings

From time to time, we may be involved in litigation relating to claims that arise out of our operations and businesses and that cover a wide range of matters, including, among others, intellectual property matters, contract disputes, insurance and property damage claims, employment claims, personal injury claims, product liability claims, environmental claims and warranty claims. Currently, there are no claims or proceedings against us that we believe will have a material adverse effect on our business, financial condition, results of operations or cash flows. However, the results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, we may incur significant costs and experience a diversion of management resources as a result of claims and litigation.

Our business and affairs are managed under the direction of our board of directors, which will consist of 12 members upon consummation of the Transactions. Our amended and restated certificate of incorporation will provide that, subject to the rights of the holders of preferred stock, the number of directors on our board of directors shall be fixed exclusively by resolution adopted by our board of directors (provided that such number shall not be less than the aggregate number of directors that the parties to the Stockholders Agreement are entitled to nominate from time to time). Our amended and restated certificate of incorporation and our amended and restated bylaws will provide that each member of our board of directors will serve for a one-year term, being elected each year by our stockholders.

When considering whether directors have the experience, qualifications, attributes or skills, taken as a whole, to enable our board of directors to satisfy its oversight responsibilities effectively in light of our business and structure, the board of directors focuses primarily on each person’s background and experience as reflected in the information discussed in each of the directors’ individual biographies set forth above. We believe that our directors provide an appropriate mix of experience and skills relevant to the size and nature of our business.

Prior to the consummation of the Transactions, we will enter into the Stockholders Agreement with our Continuing Equity Owners, pursuant to which each party thereto will agree to vote, or cause to be voted, all of their outstanding shares of our Class A common stock, Class B-1 common stock and Class B-2 common stock at any annual or special meeting of stockholders in which directors are elected, so as to cause the election of all of the directors that are nominated by the other Continuing Equity Owners. Immediately following the consummation of the Transactions, each of AES Grid Stability and Siemens Industry will directly or indirectly own 117,173,390 shares of Class B-1 common stock of Fluence Energy, Inc., which in each case represents approximately 92.2% of the combined voting power of all of Fluence Energy, Inc.’s common stock, and the Blocker Shareholder will directly or indirectly own 18,493,275 shares of Class A common stock of Fluence Energy, Inc., which represents approximately 2.9% of the combined voting power of all of Fluence Energy, Inc.’s common stock. For a description of the terms of the Stockholders Agreement, see “Certain Relationships and Related Party Transactions—Stockholders Agreement.”

Director Independence

Prior to the consummation of the Transactions, our board of directors undertook a review of the independence of our directors and considered whether any director has a relationship with us that could compromise that director’s ability to exercise independent judgment in carrying out that director’s responsibilities. Our board of directors has affirmatively determined that Cynthia Arnold, Herman Bulls, Elizabeth Fessenden and Harald von Heynitz are each an “independent director,” as defined under the Nasdaq rules. In making these determinations, our board of directors considered the current and prior relationships that each director has with the Company and all other facts and circumstances our board of directors

133

TABLE OF CONTENTS

deemed relevant in determining his or her independence, including the beneficial ownership of our capital stock by each director, and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Controlled Company Exception

After the consummation of the Transactions, AES Grid Stability and Siemens Industry, and the Continuing Equity Owners as a whole, will collectively have beneficial ownership of more than 50% of the combined voting power of our common stock. As a result, we will be a “controlled company” within the meaning of the corporate governance standards of the Nasdaq rules and intend to elect not to comply with certain corporate governance standards, including that: (1) a majority of our board of directors consists of “independent directors,” as defined under the Nasdaq rules; (2) our board of directors have a compensation committee that is comprised entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and (3) our director nominations be made, or recommended to our full board of directors, by our independent directors or by a nominations committee that is comprised entirely of independent directors and that we adopt a written charter or board resolution addressing the nominations process. We intend to rely on the foregoing exemptions provided to controlled companies under the Nasdaq rules. Therefore, immediately following the consummation of the Transactions, we may not have a majority of independent directors on our board of directors, have our director nominations be made by our independent directors or by an entirely independent nominations committee or an entirely independent compensation committee unless and until such time as we are required to do so. Accordingly, you may not have the same protections afforded to stockholders of companies that are subject to all of these corporate governance requirements. In the event that we cease to be a “controlled company” and our shares continue to be listed on the Nasdaq, we will be required to comply with these provisions within the applicable transition periods. See “Risk Factors—Risks related to the offering and ownership of our Class A common stock—We are a ‘controlled company’ within the meaning of the Nasdaq rules and, as a result, will qualify for, and intend to rely on, exemptions from certain corporate governance requirements. You may not have the same protections afforded to stockholders of companies that are subject to such corporate governance requirements.”

Committees of Our Board of Directors

Our board of directors directs the management of our business and affairs, as provided by Delaware law, and conducts its business through meetings of the board of directors and its standing committees. We will have a standing audit committee, nominating and corporate governance committee and compensation committee. In addition, from time to time, special committees may be established under the direction of the board of directors when necessary to address specific issues.

Audit Committee

Upon the consummation of the Transactions, our audit committee will consist of Cynthia Arnold, Herman Bulls, Elizabeth Fessenden and Harald von Heynitz, with Ms. Fessenden serving as chair. Rule 10A-3 of the Exchange Act and the Nasdaq rules require that our audit committee have at least one independent member upon the listing of our Class A common stock, have a majority of independent members within 90 days of the date of this prospectus and be composed entirely of independent members within one year of the date of this prospectus. Our board of directors has affirmatively determined that Herman Bulls, Cynthia Arnold, Harald von Heynitz and Elizabeth Fessenden each meet the definition of “independent director” for purposes of serving on the audit committee under the Nasdaq rules and the independence standards under Rule 10A-3 of the Exchange Act and the Nasdaq rules. Each member of our audit committee meets the financial literacy requirements of the Nasdaq rules. In addition, our board of directors has determined that each of Elizabeth Fessenden and Harald von Heynitz will qualify as an “audit committee financial expert,” as such term is defined in Item 407(d)(5) of Regulation S-K. Our board of directors will adopt a written charter for the audit committee, which will be available on our principal corporate website at https:// fluenceenergy.com substantially concurrently with the consummation of the Transactions. The information on any of our websites is deemed not to be incorporated in this prospectus or to be part of this prospectus.

Nominating and Corporate Governance Committee

•

making regular reports to our board of directors regarding the activities of the committee;

•

making periodic evaluations of the performance of the committee; and

•

annually reviewing and reassessing the charter and submitting any recommended changes to our board of directors for its consideration.

Upon the consummation of the Transactions, our nominating and corporate governance committee will consist of Cynthia Arnold, Herman Bulls, Harald von Heynitz, Lisa Krueger and Axel Meier, with Mr. Bulls serving as chair. We intend to avail ourselves of the “controlled company” exception under the Nasdaq rules, which exempts us from the requirement that we have a nominating and corporate governance committee composed entirely of independent directors. Axel Meier and Lisa Krueger do not qualify as “independent directors” under the Nasdaq rules. Our board of directors will adopt a written charter for the nominating and corporate governance committee, which will be available on our principal corporate website at https:// fluenceenergy.com substantially concurrently with the consummation of the Transactions. The information on any of our websites is deemed not to be incorporated in this prospectus or to be part of this prospectus.

Actual compensation programs that we adopt following the completion of this offering may differ materially from the currently planned programs summarized in this discussion.

2021 Summary Compensation Table

The following table sets forth information concerning the compensation of our named executive officers for our fiscal year ended September 30, 2021.

Name and Principal Position	Year		Salary ($)		Stock Awards ($)		Option Awards ($)		Total(1)

The Company and individual bonus factors required for our board of directors to determine the annual, performance-based bonuses for fiscal year 2021 are not final, and accordingly our board of directors has not yet determined the bonus amounts for our named executive officers. We anticipate that such determinations will be made in the first quarter of the fiscal year 2022, at which time the Company will disclose the amount of such bonuses.

(2)

In fiscal year 2021, we granted 20,700 phantom units to Mr. Dubuc on April 2, 2021. However, in September 2021, the Company and Mr. Dubuc mutually agreed that Mr. Dubuc would relinquish his phantom units awarded on April 2, 2021, in connection with the compensation review in anticipation of this offering.

TABLE OF CONTENTS

Base Salaries

The named executive officers receive a base salary to compensate them for services rendered to the Company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities.

The actual salaries paid to each named executive officer for 2021 are set forth in the “Summary Compensation Table” above in the column entitled “Salary.” Effective August 1, 2021, each named executive officer received a base salary increase. Mr. Dubuc’s current base salary is $450,000, Mr. Fehr’s current base salary is $350,000 and Ms. Boll’s current base salary is $325,000.

Bonus Compensation

Annual Cash Bonus

Each of our named executive officers are eligible for an annual, performance-based bonus for fiscal year 2021. The performance-based bonus has both a Company bonus factor and an individual bonus factor. The Company bonus factor is determined as a percentage, up to 200%. The individual bonus factor is determined using a five-point rating score, of which the Company will ascribe as a percentage, up to 125%. The amount of the annual bonus for each named executive officer will be determined by our board of directors. Mr. Dubuc’s target annual bonus opportunity for fiscal year 2021 was $337,500, which was 75% of his annual base salary for fiscal year 2021, which increased from 70% in August 2021. Mr. Fehr’s target annual bonus opportunity for fiscal year 2021 was $175,000, which was 50% of his annual base salary for fiscal year 2021. Ms. Boll’s target annual bonus opportunity for fiscal year 2021 was $146,250, which was 45% of her annual base salary for fiscal year 2021, which increased from 40% in August 2021. The Company and individual bonus factors required for our board of directors to determine the annual, performance-based bonuses for fiscal year 2021 are not final, and accordingly our board of directors has not yet determined the bonus amounts for our named executive officers. We anticipate that such determinations will be made in the first quarter of the fiscal year 2022, at which time the Company will disclose the amount of such bonuses.

Cash Long Term Incentive Program

In 2018, the Company approved the cash long term incentive program, pursuant to which participants were eligible to earn a cash bonus based on a three-year performance period dependent on the Company’s achievement of certain target metrics of revenue, profit and/or operating cash flow. Mr. Fehr received awards under such program for the following performance periods: fiscal year 2018 through fiscal year 2020, fiscal year 2019 through fiscal year 2021 and fiscal year 2020 through fiscal year 2022. For the performance period ending in fiscal year 2021, Mr. Fehr’s target bonus under the incentive program was $137,500. Ms. Boll only participated in such program for the fiscal year 2020 through fiscal year 2023 performance period and Mr. Dubuc did not participate in such program. The Company bonus factors required for our board of directors to determine Mr. Fehr’s bonus under this long term incentive program for the performance period ending in fiscal year 2021 are not final, and accordingly our board of directors has not yet determined the bonus amount for him. We anticipate that such determination will be made in the first quarter of the fiscal year 2022, at which time the Company will disclose the amount of such bonuses.

Equity Compensation

2020 Unit Option Plan of Fluence Energy, LLC

We maintain the 2020 Unit Option Plan of Fluence Energy, LLC (the “Existing Equity Plan”). The Existing Equity Plan provides our employees (including the named executive officers), consultants, non-employee directors, and other service providers and those of our affiliates the opportunity to participate in the equity appreciation of our business through the receipt of options to purchase Class A-1 Units. We believe that such unit options encourage a sense of proprietorship and stimulate interest in our development and financial success. Following this offering, no further awards are expected to be made under the Existing Equity Plan.

139

TABLE OF CONTENTS

In fiscal year 2021, we granted unit options to Messrs. Dubuc and Fehr and Ms. Boll on April 2, 2021, covering 68,400, 30,800, and 27,300 Class A-1 Units, respectively. Unit option awards are each scheduled to vest upon the satisfaction of a service-based requirement and a liquidity-event requirement. The service-based requirement will be satisfied over a three-year period, as to one-third of the unit option on each of the first, second and third anniversaries of the grant date, subject to the executive’s continued employment with the Company through each applicable vesting date. The liquidity-event requirement will be satisfied upon the earlier to occur of a Liquidation Event, as defined in the Existing Equity Plan (which generally means a merger, consolidation or similar transaction where the Class A-1 Units do not continue to represent a majority of the voting power of the surviving entity (or a parent thereof) or a sale, lease, transfer, license or other disposition of substantially all of the Company’s assets), or an initial public offering, which includes this offering, subject to continued service through such liquidity event.

It is anticipated that any unit options granted pursuant to the Existing Equity Plan will be converted into stock options in the Company and remain outstanding and continue to vest in accordance with their terms upon and following the effectiveness of this offering. Each Class A-1 Unit subject to an outstanding grant under the Existing Equity Plan will be converted into approximately 14.8 shares of the Company.

Fluence Energy, LLC Phantom Equity Incentive Plan

We also maintain the Fluence Energy, LLC Phantom Equity Incentive Plan (the “Existing Phantom Equity Plan”). The Existing Phantom Equity Plan is designed to further align employees’ interests with the interests of Fluence Energy, LLC, and its subsidiaries, and each phantom unit granted under the Existing Phantom Equity Plan represents a right to a potential one-time payment equal to the value of a Class A-1 Unit, less such phantom unit’s strike price (if any). In general, awards of phantom equity vest and are paid upon the six-month anniversary of an initial public offering, which includes this offering, unless otherwise determined by a majority of each of the Class A and Class B Units, subject to continued employment through such date. However, in connection with this offering, the awards for Mr. Fehr and Ms. Boll and certain other executive team members will vest with respect to 1/3 of their respective phantom units on each of the sixth, eighteenth and thirtieth-month anniversaries of this offering.

In fiscal year 2021, we granted phantom units to Messrs. Dubuc and Fehr and Ms. Boll, on April 2, 2021, which following this offering will be in respect of 306,248, 137,589 and 122,795 shares of the Company, respectively. The strike price of such phantom units was $0.00. However, in September 2021, the Company and Mr. Dubuc mutually agreed that Mr. Dubuc would relinquish his phantom units awarded on April 2, 2021, in connection with the compensation review in anticipation of this offering.

2021 Incentive Award Plan

We have adopted the 2021 Incentive Award Plan in connection with this offering in order to facilitate the grant of cash and equity incentives to directors, employees (including our named executive officers) and consultants of the Company and certain of its affiliates and to enable the Company and certain of its affiliates to obtain and retain services of these individuals, which we believe is essential to our long-term success. For additional information about the 2021 Incentive Award Plan, please see the section titled “New Incentive Plans” below.

Other Elements of Compensation

Retirement Plans

We maintain a 401(k) retirement savings plan for our employees, including our named executive officers, who satisfy certain eligibility requirements. The Internal Revenue Code allows eligible employees to defer a portion of their compensation, within prescribed limits, on a pre-tax basis through contributions to the 401(k) plan. Currently, we match employee contributions up to a maximum of 5% of the employee’s compensation per pay period. We believe that providing a vehicle for tax-deferred retirement savings though our 401(k) plan, and making matching and non-elective contributions, adds to the overall desirability of our executive compensation package and further incentivizes our employees, including our named executive officers, in accordance with our compensation policies.

140

TABLE OF CONTENTS

Employee Benefits and Perquisites

Health/Welfare Plans. All of our full-time employees, including our named executive officers, are eligible to participate in our health and welfare plans, including:

short-term and long-term disability insurance;

•

life insurance;

We believe the benefits described above are necessary and appropriate to provide a competitive compensation package to our employees, including our named executive officers.

Perquisites. We did not provide any perquisites to our named executives officers in fiscal year 2021.

No Tax Gross-Ups

We do not make gross-up payments to cover our named executive officers’ personal income taxes that may pertain to any of the compensation or benefits paid or provided by the Company.

The unit option awards vest upon the satisfaction of both a service-based requirement and a liquidity-event requirement. The service-based requirement will be satisfied over a three-year period, as to one-third of the unit option on each of the first, second and third anniversaries of April 2, 2021, subject to the executive’s continued employment with the Company through each applicable vesting date. The liquidity-event requirement will be satisfied upon the earlier to occur of a Liquidation Event or an initial public offering, which includes this offering, subject to continued service through such liquidity event. The number of options set forth herein represents the number of shares of Class A common stock subject to such options.

Executive Employment and Severance Arrangements

Our named executive officers are currently not party to any employment agreements.

2021 Incentive Award Plan

The plan administrator may also institute and determine the terms and conditions of an “exchange program,” which could provide for the surrender or cancellation, transfer, or reduction or increase of exercise price, of outstanding awards, subject to the limitations provided for in the 2021 Plan. The plan administrator’s determinations under the 2021 Plan are in its sole discretion and will be final and binding on all persons having or claiming any interest in the 2021 Plan or any award thereunder.

Limitation on Awards and Shares Available

The number of shares initially available for issuance under awards granted pursuant to the 2021 Plan will be 9,500,000. No more than 9,500,000 shares of common stock may be issued upon the exercise of incentive stock options under the 2021 Plan. Shares issued under the 2021 Plan may be authorized but unissued shares, shares purchased in the open market or treasury shares.

If an award under the 2021 Plan expires, lapses or is terminated, exchanged for cash, surrendered, repurchased, cancelled without having been fully exercised or forfeited, then any shares subject to such award will, as applicable, become or again be available for new grants under the 2021 Plan. Shares delivered to the Company by a participant to satisfy the applicable exercise price or purchase price of an award and/or satisfy any applicable tax withholding obligation (including shares retained by the Company from the award being exercised or purchased and/or creating the tax obligation), will not become or again be available for award grants under the 2021 Plan. The payment of dividend equivalents in cash in conjunction with any outstanding awards will not count against the number of shares available for issuance under the 2021 Plan. Awards granted under the 2021 Plan upon the assumption of, or in substitution or exchange for, awards authorized or outstanding under a qualifying equity plan maintained by an entity with which we enter into a merger, consolidation, acquisition or similar corporate transaction will not reduce the shares available for grant under the 2021 Plan. The plan administrator may, in its discretion, make adjustments to the maximum number and kind of shares which may be issued under the 2021 Plan upon the occurrence of a merger, reorganization, consolidation, combination, amalgamation, recapitalization, liquidation, dissolution, or sale, transfer, exchange or other disposition of all or substantially all of the assets of the Company, or sale or exchange of common stock or other securities of the Company, change in control, issuance of warrants or other rights to purchase common stock or other securities of the Company or similar corporate transaction or event.

Awards

The 2021 Plan provides for the grant of stock options, including incentive stock options, or ISOs, and nonqualified stock options, or NSOs; restricted stock; dividend equivalents; restricted stock units, or RSUs; stock appreciation rights, or SARs; and other stock or cash-based awards. Certain awards under the 2021 Plan may constitute or provide for a deferral of compensation, subject to Section 409A of the Code, which may impose additional requirements on the terms and conditions of such awards. All awards under the 2021 Plan will be set forth in award agreements, which will detail the terms and conditions of the awards, including any applicable vesting and payment terms and post-termination exercise limitations. A brief description of each award type follows.

Stock options. Stock options provide for the purchase of shares of common stock in the future at an exercise price set on the grant date. ISOs, by contrast to NSOs, may provide tax deferral beyond exercise and favorable capital gains tax treatment to their holders if certain holding period and other requirements of the Code are satisfied. Unless otherwise determined by the plan administrator and only with respect to certain substitute options granted in connection with a corporate transaction, the exercise price of a stock option will not be less than 100% of the fair market value of the underlying share on the date of grant (or 110% in the case of ISOs granted to certain significant shareholders). Unless otherwise determined by the plan administrator in accordance with applicable laws, the term of a stock option may not be longer than ten years (or five years in the case of ISOs granted to certain significant shareholders). Vesting conditions determined by the plan administrator may apply to stock options and may include continued service,

144

TABLE OF CONTENTS

performance and/or other conditions as the plan administrator may determine. ISOs may be granted only to the Company’s U.S. employees and employees of the Company’s present or future parent or subsidiaries, if any.

SARs. SARs entitle their holder, upon exercise, to receive from the Company an amount equal to the appreciation of the shares subject to the award between the grant date and the exercise date. The exercise price of a SAR will not be less than 100% of the fair market value of the underlying share on the date of grant (except with respect to certain substitute SARs granted in connection with a corporate transaction), and unless otherwise determined by the plan administrator in accordance with applicable laws, the term of a SAR may not be longer than ten years. Vesting conditions determined by the plan administrator may apply to SARs and may include continued service, performance and/or other conditions as the plan administrator may determine.

Restricted stock and RSUs. Restricted stock is an award of nontransferable shares of common stock that remain forfeitable unless and until specified conditions are met, and which may be subject to a purchase price. RSUs are unfunded, unsecured rights to receive, on the applicable settlement date, common stock or an amount in cash or other consideration determined by the plan administrator to be of equal value as of such settlement date, subject to certain vesting conditions and other restrictions during the applicable restriction period or periods set forth in the award agreement. RSUs may be accompanied by the right to receive the equivalent value of dividends paid on shares of common stock prior to the delivery of the underlying shares, subject to the same restrictions on transferability and forfeitability as the RSUs with respect to which the dividend equivalents are granted. Delivery of the shares underlying RSUs may be deferred under the terms of the award or at the election of the participant, if the plan administrator permits such a deferral and in accordance with applicable law. Conditions applicable to restricted stock and RSUs may be based on continuing service, performance and/or such other conditions as the plan administrator may determine.

Other stock or cash-based awards. Other stock or cash-based awards may be granted to participants, including awards entitling participants to receive common stock to be delivered in the future and including annual or other periodic or long-term cash bonus awards (whether based on specified performance criteria or otherwise). Such awards may be paid in common stock, cash or other property, as the administrator determines. Other stock or cash-based awards may be granted to participants and may also be available as a payment form in the settlement of other awards, as standalone payments and as payment in lieu of compensation payable to any individual who is eligible to receive awards. The plan administrator will determine the terms and conditions of other stock or cash-based awards, which may include vesting conditions based on continued service, performance and/or other conditions.

Performance Awards

Performance awards include any of the foregoing awards that are granted subject to vesting and/or payment based on the attainment of specified performance goals or other criteria the plan administrator may determine, which may or may not be objectively determinable. Performance criteria upon which performance goals are established by the plan administrator may include: net earnings or losses (either before or after one or more of interest, taxes, depreciation, amortization and non-cash equity-based compensation expense); gross or net sales or revenue or sales or revenue growth; net income (either before or after taxes) or adjusted net income; profits (including, but not limited to, gross profits, net profits, profit growth, net operation profit or economic profit), profit return ratios or operating margin; budget or operating earnings (either before or after taxes or before or after allocation of corporate overhead and bonus); cash flow (including operating cash flow and free cash flow or cash flow return on capital); return on assets; return on capital or invested capital; cost of capital; return on shareholders’ equity; total shareholder return; return on sales; costs, reductions in costs and cost control measures; expenses; working capital; earnings or loss per share; adjusted earnings or loss per share; price per share or dividends per share (or appreciation in or maintenance of such price or dividends); regulatory achievements or compliance; implementation, completion or attainment of objectives relating to research, development, regulatory, commercial or strategic milestones or developments; market share; economic value or economic value added models; division, group or corporate financial goals; customer satisfaction/growth; customer service; employee satisfaction; recruitment and maintenance of personnel; human resources management; supervision of litigation and other legal matters; strategic partnerships and transactions; financial ratios (including those measuring

145

TABLE OF CONTENTS

liquidity, activity, profitability or leverage); debt levels or reductions; sales-related goals; financing and other capital raising transactions; cash on hand; acquisition activity; investment sourcing activity; marketing initiatives; and other measures of performance selected by the Company’s board of directors or its applicable committee, any of which may be measured in absolute terms or as compared to any incremental increase or decrease. Such performance goals also may be based solely by reference to the Company’s performance or the performance of its subsidiary, division, business segment or business unit, or based upon performance relative to performance of other companies or upon comparisons of any of the indicators of performance relative to performance of other companies. When determining performance goals, the plan administrator may provide for exclusion of the impact of an event or occurrence which the plan administrator determines should appropriately be excluded, including, without limitation, non-recurring charges or events, acquisitions or divestitures, changes in the corporate or capital structure, events not directly related to the business or outside of the reasonable control of management, foreign exchange gains or losses, and legal, regulatory, tax or accounting changes.

Provisions of the 2021 Plan Relating to Director Compensation

The 2021 Plan provides that the plan administrator may establish compensation for non-employee independent directors from time to time subject to the 2021 Plan’s limitations. The plan administrator may establish the terms, conditions and amounts of all such non-employee independent director compensation in its discretion and in the exercise of its business judgment, taking into account such factors, circumstances and considerations as it shall deem relevant from time to time, provided that the sum of any cash compensation or other compensation and the grant date fair value (as determined in accordance with ASC 718, or any successor thereto) of any equity awards granted as compensation for services as a non-employee independent director during any calendar year may not exceed $500,000, increased to $750,000 for a non-employee independent directors initial fiscal year of service as a non-employee independent director. The plan administrator may make exceptions to this limits for individual non-employee independent directors in extraordinary circumstances, as the plan administrator may determine in its discretion, provided that the non-employee independent director receiving such additional compensation may not participate in the decision to award such compensation or in other contemporaneous compensation decisions involving non-employee independent directors.

Certain Transactions

In connection with certain transactions and events affecting common stock, including, without limitation, any dividend or other distribution, reorganization, merger, consolidation, recapitalization, or sale of all or substantially all of the assets of the Company, or sale or exchange of common stock or other securities of the Company, a change in control, or issuance of warrants or other rights to purchase common stock or other securities of the Company, or similar corporate transaction or event, or change in any applicable laws or accounting principles, the plan administrator has broad discretion to take action under the 2021 Plan to prevent the dilution or enlargement of intended benefits, facilitate such transaction or event, or give effect to such change in applicable laws or accounting principles. This includes canceling awards in exchange for either an amount in cash or other property with a value equal to the amount that would have been obtained upon exercise or settlement of the vested portion of such award or realization of the participant’s rights under the vested portion of such award, accelerating the vesting of awards, providing for the assumption or substitution of awards by a successor entity, adjusting the number and type of shares available, replacing awards with other rights or property and/or terminating awards under the 2021 Plan.

For purposes of the 2021 Plan, a “change in control” means and includes each of the following:

•

a transaction or series of transactions (other than certain public offerings of common stock) whereby any “person” or related “group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act) (other than the Company or its subsidiaries or any employee benefit plan maintained by the Company or any of its subsidiaries or a “person” that, prior to such transaction, directly or indirectly controls, is controlled by, or is under common control with, the Company, Siemens, AES or any “person” or related “group” of “persons” (as such terms are used in Sections 13(d) and 14(d)(2) of the Exchange Act) of which AES or Siemens is a member so long as AES and/or Siemens (individually or in the aggregate) directly or directly has beneficial ownership of a

146

TABLE OF CONTENTS

greater percentage of the combined voting power of the Company’s securities outstanding immediately after such acquisition than any other member of such “group”) directly or indirectly acquires beneficial ownership (within the meaning of Rule 13d-3 under the Exchange Act) of the Company’s securities possessing more than 50% of the total combined voting power of the Company’s securities outstanding immediately after such acquisition; or

•

during any period of two consecutive years, individuals who, at the beginning of such period, constitute the Company board of directors together with any new directors (other than a director designated by a person who shall have entered into an agreement with the Company to effect a change in control transaction) whose election by the Company board of directors or nomination for election by the Company’s shareholders was approved by a vote of at least seventy-five percent of the directors or was made by AES, Siemens or QIA pursuant to the terms of the Stockholders Agreements, cease for any reason to constitute a majority of the Company board of directors; or

•

the consummation by the Company (whether directly or indirectly) of (x) a merger, consolidation, reorganization, or business combination or (y) a sale or other disposition of all or substantially all of the Company’s assets in any single transaction or series of related transactions or (z) the acquisition of assets or stock of another entity, in each case other than a transaction:

•

which results in the Company’s voting securities outstanding immediately before the transaction continuing to represent either by remaining outstanding or by being converted into voting securities of the company or the person that, as a result of the transaction, controls, directly or indirectly, the company or owns, directly or indirectly, all or substantially all of the Company’s assets or otherwise succeeds to the Company’s business, directly or indirectly, at least a majority of the combined voting power of the successor entity’s outstanding voting securities immediately after the transaction, and

•

after which no person or group beneficially owns voting securities representing 50% or more of the combined voting power of the successor entity; provided, however, that no person or group shall be treated as beneficially owning 50% or more of the combined voting power of the successor entity solely as a result of the voting power held in the Company prior to the consummation of the transaction.

Foreign Participants, Claw-back Provisions, Transferability and Participant Payments

With respect to foreign participants, the plan administrator may modify award terms, establish subplans and/or adjust other terms and conditions of awards, subject to the share limits described above. All awards will be subject to the provisions of any claw-back policy implemented by the Company to the extent set forth in such claw-back policy or in the applicable award agreement. With limited exceptions for estate planning, domestic relations orders, certain beneficiary designations and the laws of descent and distribution, awards under the 2021 Plan are generally non-transferable prior to vesting and are exercisable only by the participant. With regard to tax withholding obligations arising in connection with awards under the 2021 Plan and exercise price obligations arising in connection with the exercise of stock options under the 2021 Plan, the plan administrator may, in its discretion and subject to any applicable blackout or lock-up periods, accept cash, wire transfer, or check, shares of common stock that meet specified conditions (a market sell order) or such other consideration as it deems suitable or any combination of the foregoing.

Plan Amendment and Termination

The Company’s board of directors may amend, suspend or terminate the 2021 Plan at any time. However, no amendment, other than an increase in the number of shares available under the 2021 Plan, in excess of the initial pool and annual increase as described above, may materially and adversely affect any award outstanding at the time of such amendment without the affected participant’s consent. The Company’s board of directors will obtain stockholder approval for any plan amendment to the extent necessary to comply with applicable laws. The plan administrator will have the authority, without the approval of the Company’s shareholders, to amend any outstanding award, including by substituting another award of the same or different type, changing the exercise or settlement date, or converting an ISO to an NSO. No award may be granted pursuant to the 2021 Plan after the expiration of the 2021 Plan. The 2021 Plan is scheduled to remain in effect until the earlier of (i) the tenth anniversary of the date on which the Company’s

147

TABLE OF CONTENTS

board of directors adopts the 2021 Plan and (ii) the earliest date as of which all awards granted under the 2021 Plan have been satisfied in full or terminated and no shares approved for issuance under the 2021 Plan remain available to be granted under new awards.

Securities Laws

The 2021 Plan is intended to conform to all provisions of the Securities Act, the Exchange Act and any and all regulations and rules promulgated by the SEC thereunder, including, without limitation, Exchange Act Rule 16b-3. The 2021 Plan will be administered, and awards will be granted and may be exercised, only in such a manner as to conform to such laws, rules and regulations.

Federal Income Tax Consequences

The material federal income tax consequences of the 2021 Plan under current federal income tax law are summarized in the following discussion, which deals with the general U.S. federal income tax principles applicable to the 2021 Plan. The following discussion is based upon laws, regulations, rulings and decisions now in effect, all of which are subject to change. Foreign, state and local tax laws, and employment, estate and gift tax considerations are not discussed due to the fact that they may vary depending on individual circumstances and from locality to locality.

Stock options and SARs. A 2021 Plan participant generally will not recognize taxable income and the Company generally will not be entitled to a tax deduction upon the grant of a stock option or SAR. The tax consequences of exercising a stock option and the subsequent disposition of the shares received upon exercise will depend upon whether the option qualifies as an ISO or an NSO. Upon exercising an NSO when the fair market value of common stock is higher than the exercise price of the option, an 2021 Plan participant generally will recognize taxable income at ordinary income tax rates equal to the excess of the fair market value of the stock on the date of exercise over the purchase price, and the Company (or its subsidiaries, if any) generally will be entitled to a corresponding tax deduction for compensation expense, in the amount equal to the amount by which the fair market value of the shares purchased exceeds the purchase price for the shares. Upon a subsequent sale or other disposition of the option shares, the participant will recognize a short-term or long-term capital gain or loss in the amount of the difference between the sales price of the shares and the participant’s tax basis in the shares.

Upon exercising an ISO, 2021 Plan participant generally will not recognize taxable income, and the Company will not be entitled to a tax deduction for compensation expense. However, upon exercise, the amount by which the fair market value of the shares purchased exceeds the purchase price will be an item of adjustment for alternative minimum tax purposes. The participant will recognize taxable income upon a sale or other taxable disposition of the option shares. For federal income tax purposes, dispositions are divided into two categories: qualifying and disqualifying. A qualifying disposition generally occurs if the sale or other disposition is made more than two years after the date the option was granted and more than one year after the date the shares are transferred upon exercise. If the sale or disposition occurs before these two periods are satisfied, then a disqualifying disposition generally will result.

Upon a qualifying disposition of ISO shares, the participant will recognize long-term capital gain in an amount equal to the excess of the amount realized upon the sale or other disposition of the shares over their purchase price. If there is a disqualifying disposition of the shares, then the excess of the fair market value of the shares on the exercise date (or, if less, the price at which the shares are sold) over their purchase price will be taxable as ordinary income to the participant. If there is a disqualifying disposition in the same year of exercise, it eliminates the item of adjustment for alternative minimum tax purposes. Any additional gain or loss recognized upon the disposition will be recognized as a capital gain or loss by the participant.

The Company will not be entitled to any tax deduction if the participant makes a qualifying disposition of ISO shares. If the participant makes a disqualifying disposition of the shares, the Company should be entitled to a tax deduction for compensation expense in the amount of the ordinary income recognized by the participant.

Upon exercising or settling a SAR, 2021 Plan participant will recognize taxable income at ordinary income tax rates, and the Company should be entitled to a corresponding tax deduction for compensation

148

TABLE OF CONTENTS

expense, in the amount paid or value of the shares issued upon exercise or settlement. Payments in shares will be valued at the fair market value of the shares at the time of the payment, and upon the subsequent disposition of the shares the participant will recognize a short-term or long-term capital gain or loss in the amount of the difference between the sales price of the shares and the participant’s tax basis in the shares.

Restricted stock and RSUs. 2021 Plan participant generally will not recognize taxable income at ordinary income tax rates and the Company generally will not be entitled to a tax deduction upon the grant of restricted stock or RSUs. Upon the termination of restrictions on restricted stock or the payment of RSUs, the participant will recognize taxable income at ordinary income tax rates, and the Company should be entitled to a corresponding tax deduction for compensation expense, in the amount paid to the participant or the amount by which the then fair market value of the shares received by the participant exceeds the amount, if any, paid for them. Upon the subsequent disposition of any shares, the participant will recognize a short-term or long-term capital gain or loss in the amount of the difference between the sales price of the shares and the participant’s tax basis in the shares.

However, 2021 Plan participant granted restricted stock that is subject to forfeiture or repurchase through a vesting schedule such that it is subject to a risk of forfeiture (as defined in Section 83 of the Code) may make an election under Section 83(b) of the Code to recognize taxable income at ordinary income tax rates, at the time of the grant, in an amount equal to the fair market value of the shares of common stock on the date of grant, less the amount paid, if any, for the shares. The Company will be entitled to a corresponding tax deduction for compensation, in the amount recognized as taxable income by the participant. If a timely Section 83(b) election is made, the participant will not recognize any additional ordinary income on the termination of restrictions on restricted stock, and the Company will not be entitled to any additional tax deduction.

Other stock or cash-based awards. 2021 Plan participant will not recognize taxable income and the Company will not be entitled to a tax deduction upon the grant of other stock or cash-based awards until cash or shares are paid or distributed to the participant. At that time, any cash payments or the fair market value of shares that the participant receives will be taxable to the participant at ordinary income tax rates and the Company should be entitled to a corresponding tax deduction for compensation expense. Payments in shares will be valued at the fair market value of the shares at the time of the payment. Upon the subsequent disposition of the shares, the participant will recognize a short-term or long-term capital gain or loss in the amount of the difference between the sales price of the shares and the participant’s tax basis in the shares.

Section 162(m) of the Code. Section 162(m) of the Code currently limits the deduction certain employers may take for otherwise deductible compensation payable to certain executive officers of the employer to the extent the compensation paid to such an officer for the year exceeds $1 million. Payment of awards under the 2021 Plan could result in an officer (or any other employee covered by Section 162(m) in the future) receiving compensation in excess of $1 million in a year and thus a loss of deductibility for the Company.

Section 280G of the Code. Section 280G of the Code limits the deduction that the employer may take for otherwise deductible compensation payable to certain individuals if the compensation constitutes an “excess parachute payment.” Excess parachute payments arise from payments made to disqualified individuals that are in the nature of compensation and are contingent on changes in ownership or control of the employer or certain affiliates. Accelerated vesting or payment of awards under the 2021 Plan upon a change in ownership or control of the employer or its affiliates could result in excess parachute payments. In addition to the deduction limitation applicable to the employer, a disqualified individual receiving an excess parachute payment is subject to a 20% excise tax on the amount thereof.

Section 409A of the Code. Section 409A of the Code (“Section 409A”) imposes an additional 20% tax and interest on an individual receiving non-qualified deferred compensation under a plan that fails to satisfy certain requirements. For purposes of Section 409A, “non-qualified deferred compensation” could include equity-based incentive programs, including certain stock options, stock appreciation rights and RSU programs. Generally speaking, Section 409A does not apply to incentive stock options, non-discounted non-qualified stock options and stock appreciation rights if no deferral is provided beyond exercise, or restricted stock.

149

TABLE OF CONTENTS

The awards made pursuant to the 2021 Plan are expected to be designed in a manner intended to be exempt from, or comply with, the requirements of Section 409A of the Code. However, if the 2021 Plan or any award thereunder fails to be maintained and administered in compliance with Section 409A, a participant could be subject to the additional taxes and interest.

State, local and foreign tax consequences may in some cases differ from the United States federal income tax consequences described above. The foregoing summary of the United States federal income tax consequences in respect of the 2021 Plan is for general information only. Interested parties should consult their own advisors as to specific tax consequences of their awards.

The 2021 Plan is not subject to the Employee Retirement Income Security Act of 1974, as amended, and is not intended to be qualified under Section 401(a) of the Code.

CERTAIN RELATIONSHIPS AND RELATED PARTY TRANSACTIONS

The following are summaries of certain provisions of our related party agreements and are qualified in their entirety by reference to all of the provisions of such agreements. Because these descriptions are only summaries of the applicable agreements, they do not necessarily contain all of the information that you may find useful. We, therefore, urge you to review the agreements in their entirety. Copies of the forms of the agreements have been filed as exhibits to the registration statement of which this prospectus is a part, and are available electronically on the website of the SEC at www.sec.gov.

Related Party Agreements in Effect Prior to the Transactions

Prior to the completion of this offering and the other Transactions, we were owned by AES Grid Stability and Siemens Industry and, beginning in June 2021, QFH (as a result of the completion of the transaction contemplated by our subscription agreement with QFH, dated as of December 27, 2020, for the issuance of 1,250,000 Class B units for a total value of $125.0 million). During that time, Fluence Energy, LLC entered into various agreements that governed its relationship with those shareholders, including:

•

the Fluence Energy LLC Second Amended and Restated LLC Agreement, which will be superseded by the Fluence Energy LLC Agreement upon completion of this offering and the other Transactions,

•

a master sales cooperation agreement with Siemens Industry and a commercial cooperation agreement with AES,

We have entered into sales agency agreements with Siemens, in certain locations, to utilize its sales force. In addition, in the ordinary course of business, both AES and Siemens purchase our products and services for energy storage projects in multiple countries, and Siemens is a supplier to us of goods and services that we use when delivering and maintaining energy storage projects for customers. Occasionally, in the ordinary course of business Siemens and Fluence act as a consortium to deliver energy storage projects for customers.

We have entered into a patent assignment agreement with Siemens pursuant to which Siemens has assigned, sold and transferred to us the entire right, title and interest in the United States and all foreign countries, in and to any and all inventions and improvements disclosed in certain identified patent applications, pending patent applications and granted letter patents.

On September 9, 2021, we entered into an intellectual property assignment agreement with AES (the “Patent Transfer Agreement”), whereby AES assigned certain intellectual property to Fluence that we had previously utilized pursuant to a license from AES. In connection with the Patent Transfer Agreement, we entered into a License Agreement with AES (the “License-Back Agreement”), whereby we granted AES perpetual, non-exclusive, worldwide rights to do any acts within the current and future fields of business of AES, which are not activities which are exclusive to us and which would otherwise infringe any of the intellectual property just transferred to us, under fair, reasonable and non-discriminatory royalty terms, to be negotiated by the parties thereto. The Patent Transfer Agreement contains customary limitation of liability provisions.

Prior to the completion of this offering and the other Transactions, AES and Siemens provided support services to us in the ordinary course of business, pursuant to various support agreements, such as

151

TABLE OF CONTENTS

engineering support, software development, HR, and payroll services, and seconding a limited number of employees to service for Fluence. Prior to the completion of this offering and the other Transactions, AES and Siemens Industry provided revolving credit support for our business pursuant to an Amended and Restated Credit Support and Reimbursement Agreement.

Prior to August 1, 2021, Manuel Perez Dubuc, our chief executive officer, was seconded from AES, which paid Mr. Dubuc’s salary. We reimbursed AES for that expense. After August 2, 2021, Mr. Dubuc became our employee.

On April 28, 2021 and June 3, 2021, we borrowed $25.0 million and $25.0 million from AES and Siemens Industry, respectively, in the form of one-year promissory notes, each bearing annual interest at 2.86%. On May 3, 2021, we borrowed $25.0 million from Siemens Industry, in the form of a one-year promissory note with an annual interest rate of 2.86%. The proceeds were used for general working capital needs. As of June 22, 2021, the total $75.0 million in borrowings from AES and Siemens Industry were paid off in full.

Prior to the completion of this offering and the other Transactions, Fluence Energy, LLC entered into customary indemnification agreements with the individual members of the Fluence Energy, LLC Board of Directors, as it was constituted at that time.

For more information regarding transactions between us, AES and Siemens prior to consummation of this offering and the Transactions, see Note 13 of “Notes to Condensed Combined Financial Statements” for the two fiscal years ended September 30, 2020 and the nine-months ended June 30, 2021 and 2022 included in this prospectus.

Promissory Notes

In connection with the bridge financing, Fluence Energy, LLC issued a $25.0 million promissory note to each of Siemens Industry and AES Grid Stability. The Promissory Notes are unsecured and (i) the AES Promissory Note has a maturity date of August 11, 2022 and (ii) the Siemens Promissory Note has a maturity date of December 31, 2021. If we complete a private placement or public offering of certain equity securities prior to the maturity date, the Promissory Notes and all accrued interest thereunder will automatically and without notice be due and payable within five business days. The Promissory Notes bear interest at 2.86% per annum through and until the earliest of the maturity date thereunder and or a mandatory prepayment event, at which time the interest rate will increase by an additional 2%. The proceeds from the Promissory Notes are being used by Fluence Energy, LLC to provide additional liquidity and to fund ongoing working capital needs.

Related Party Agreements after the Transactions

In connection with this offering, we will amend certain of our existing affiliate agreements and enter into a number of new agreements with those shareholders and their affiliates in order to provide a framework for our relationship with those shareholders, including a Tax Receivable Agreement, the Fluence Energy LLC Agreement, the Stockholders Agreement, the Registration Rights Agreement, certain intellectual property and trademark license agreements, an amended and restated equipment and services purchase agreement, an amended and restated storage core frame purchase agreement, a credit support and reimbursement agreement with Siemens Industry and AES, an amended and restated cooperation agreement with AES, certain employment agreements, and indemnification agreements with each of our directors and executive officers, each as described below.

We do not currently expect to enter into additional agreements with our shareholders outside the ordinary course of business, or with any of our directors, officers or other affiliates, other than those specified below. However, after the closing of this offering, in the ordinary course of our business we do expect that both AES and Siemens will continue to purchase our products and services for energy storage projects in multiple countries, and Siemens will continue to be a supplier to us of goods and services that we

use when delivering and maintaining energy storage projects for customers. Occasionally, in the ordinary course of business, Siemens and Fluence will continue to act as a consortium to deliver energy storage projects for customers.

Although we do not currently have plans to procure new support services from our shareholders or their affiliates, it is possible that we might do so in the future. After the closing of this offering, any transactions with shareholders, directors, officers or other affiliates will be subject to requirements of the Sarbanes-Oxley Act and SEC rules and regulations.

The Transactions

In connection with the Transactions, we will engage in certain transactions with certain entities which are or will become holders of 5% or more of our voting securities upon the consummation of the Transactions. These transactions are described in “Our Organizational Structure.”

We intend to use the net proceeds from this offering (including any net proceeds from any exercise of the underwriters’ option to purchase additional shares of Class A common stock) to purchase 31,000,000 LLC Interests (or 35,650,000 LLC Interests if the underwriters exercise in full their option to purchase additional shares of Class A common stock) directly from Fluence Energy, LLC at a price per unit equal to the initial public offering price per share of Class A common stock in this offering less the underwriting discount and estimated offering expenses payable by us.

Tax Receivable Agreement

We may obtain an increase in our share of the tax basis of the assets of Fluence Energy, LLC and certain of its subsidiaries in the future, when (as described below under “—Fluence Energy LLC Agreement”) a Founder receives Class A common stock or cash from us or from Fluence Energy, LLC in connection with an exercise of such Founder’s right to have LLC Interests redeemed by Fluence Energy, LLC or, at our election, exchanged, or when Fluence Energy, LLC makes, or is deemed to make, certain distributions to the Founders or upon certain other transactions. We intend to treat such redemptions or exchanges as our direct purchase of LLC Interests from such Founder for U.S. federal income and other applicable tax purposes, regardless of whether such LLC Interests are surrendered by a Founder to Fluence Energy, LLC for redemption or sold to us upon the exercise of our election to acquire such LLC Interests directly (any resulting basis increases, together with the basis increases arising from certain distributions (or deemed distributions) from Fluence Energy, LLC, the “Basis Adjustments”). Any Basis Adjustment, may have the effect of reducing the amounts that we would otherwise pay in the future to various tax authorities. The Basis Adjustments may also decrease gains (or increase losses) on future dispositions of certain assets to the extent tax basis is allocated to those assets.

In connection with the transactions described above, we will enter into a Tax Receivable Agreement with Fluence Energy, LLC and the Founders that will provide for the payment by Fluence Energy, Inc. to such Founders of 85% of the amount of certain tax benefits, if any, that Fluence Energy, Inc. actually realizes, or in some circumstances is deemed to realize in its tax reporting, arising from the transactions described above, including, the Basis Adjustments and certain other tax benefits arising from payments made under the Tax Receivable Agreement. Fluence Energy, LLC will have in effect an election under Section 754 of the Code effective for each taxable year in which a redemption or exchange (including deemed exchange) of LLC Interests for Class A common stock or cash occurs or when Fluence Energy, LLC makes (or is deemed to make) certain distributions. These Tax Receivable Agreement payments are not conditioned upon one or more of the Founders maintaining a continued ownership interest in Fluence Energy, LLC. If a Founder transfers LLC Interests but does not assign to the transferee of such units its rights under the Tax Receivable Agreement, such Founder generally will continue to be entitled to receive payments under the Tax Receivable Agreement arising in respect of a subsequent redemption or exchange of such LLC Interests. In general, the Founders’ rights under the Tax Receivable Agreement may not be assigned, sold, pledged or otherwise alienated or transferred to any person, other than certain permitted transferees, without our prior written consent (not to be unreasonably withheld) and such person’s becoming a party to the Tax Receivable Agreement and agreeing to succeed to the applicable Founder’s interest therein.

TABLE OF CONTENTS

The actual Basis Adjustments, as well as any amounts paid to the Founders under the Tax Receivable Agreement will vary depending on a number of factors, including:

•

the timing of any future redemptions or exchanges—for instance, the increase in any tax deductions will vary depending on the fair value, which may fluctuate over time, of the depreciable or amortizable assets of Fluence Energy, LLC at the time of each redemption, exchange or distribution (or deemed distribution) as well as the amount of remaining existing tax basis at the time of such redemption, exchange or distribution (or deemed distribution);

•

the price of shares of our Class A common stock at the time of the purchases from the Founders in connection with this offering and any applicable redemptions or exchanges—the Basis Adjustments, as well as any related increase in any tax deductions, are directly related to the price of shares of our Class A common stock at the time of such purchases or future redemptions or exchanges;

•

the extent to which such redemptions or exchanges are taxable—if a redemption or exchange is not taxable for any reason, increased tax deductions will not be available; and

•

the amount and timing of our income—the Tax Receivable Agreement generally will require us to pay 85% of the tax benefits as and when those benefits are treated as realized under the terms of the Tax Receivable Agreement. If Fluence Energy, Inc. does not have sufficient taxable income to realize any of the applicable tax benefits, it generally will not be required (absent a material breach of a material obligation under the Tax Receivable Agreement, change of control or other circumstances requiring an early termination payment and treating any outstanding LLC Interests held by the Founders as having been exchanged for Class A common stock for purposes of determining such early termination payment) to make payments under the Tax Receivable Agreement for that taxable year because no tax benefits will have been actually realized. However, any tax benefits that do not result in realized tax benefits in a given taxable year may generate tax attributes that may be utilized to generate tax benefits in previous or future taxable years. The utilization of any such tax attributes will result in payments under the Tax Receivable Agreement.

For purposes of the Tax Receivable Agreement, cash savings in income tax will be computed by comparing our actual U.S. federal, state and local income tax liability to the amount of such taxes that we would have been required to pay, had there been no Basis Adjustments, had the Tax Receivable Agreement not been entered into and had there been no tax benefits to us as a result of any payments made under the Tax Receivable Agreement; provided that, for purposes of determining cash savings with respect to state and local income taxes, we will use an assumed tax rate. The Tax Receivable Agreement will generally apply to each of our taxable years, beginning with the first taxable year ending after the consummation of the Transactions. There is no maximum term for the Tax Receivable Agreement; however, the Tax Receivable Agreement may be terminated by us pursuant to an early termination procedure that requires us to pay the Founders an agreed-upon amount equal to the estimated present value of the remaining payments to be made under the agreement (calculated with certain assumptions, including regarding tax rates and utilization of the Basis Adjustments and other benefits).

The payment obligations under the Tax Receivable Agreement are obligations of Fluence Energy, Inc. and not of Fluence Energy, LLC. We anticipate funding ordinary course payments under the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under any future debt agreements.

Although the actual timing and amount of any payments that may be made under the Tax Receivable Agreement will vary, we expect that the payments that we may be required to make to the Founders could be substantial. Any payments made by us to the Founders under the Tax Receivable Agreement will generally reduce the amount of overall cash flow that might have otherwise been available to us or to Fluence Energy, LLC and, to the extent that we are unable to make payments under the Tax Receivable Agreement for any reason, the unpaid amounts will be deferred and will accrue interest until paid by us; provided, however, that nonpayment for a specified period may constitute a material breach of a material obligation under the Tax Receivable Agreement and, therefore, may accelerate payments due under the Tax Receivable Agreement. We anticipate funding ordinary course payments under the Tax Receivable Agreement from cash flow from operations of our subsidiaries, available cash or available borrowings under any future debt agreements. Decisions made by us in the course of running our business, such as with respect to mergers, asset

154

TABLE OF CONTENTS

sales, other forms of business combinations or other changes in control, may influence the timing and amount of payments that are received by a redeeming Founder under the Tax Receivable Agreement. For example, the earlier disposition of assets following an exchange or acquisition transaction will generally accelerate payments under the Tax Receivable Agreement and increase the present value of such payments. In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative effect on our liquidity and could have the effect of delaying, deferring or preventing certain mergers, asset sales, other forms of business combinations or other changes of control.

The Tax Receivable Agreement provides that if certain mergers, asset sales, other forms of business combination, or other changes of control were to occur or if we materially breach any of our material obligations under the Tax Receivable Agreement, and in either such case the Continuing Equity Owners elect an early termination of the Tax Receivable Agreement, or if, at any time, we elect an early termination of the Tax Receivable Agreement, then the Tax Receivable Agreement will terminate and our obligations, or our successor’s obligations, under the Tax Receivable Agreement would accelerate and become due and payable, based on certain assumptions, Fluence Energy, including an assumption that we would have sufficient taxable income to fully utilize all potential future tax benefits that are subject to the Tax Receivable Agreement. In those circumstances, Founders would be deemed to exchange any remaining outstanding LLC Interests for Class A common stock and would generally be entitled to payments under the Tax Receivable Agreement resulting from such deemed exchanges.

We may elect to completely terminate the Tax Receivable Agreement early only with the written approval of each of a majority of Fluence Energy, Inc.’s “independent directors” (within the meaning of Rule 10A-3 promulgated under the Exchange Act and the Nasdaq rules).

As a result of the foregoing, we could be required to make an immediate cash payment equal to the present value of the anticipated future tax benefits that are the subject of the Tax Receivable Agreement, which payment may be made significantly in advance of the actual realization, if any, of such future tax benefits. We also could be required to make cash payments to the Founders that are greater than the specified percentage of the actual benefits we ultimately realize in respect of the tax benefits that are subject to the Tax Receivable Agreement. In these situations, our obligations under the Tax Receivable Agreement could have a substantial negative impact on our liquidity and could have the effect of delaying, deferring, or preventing certain mergers, asset sales, other forms of business combination, or other changes of control. There can be no assurance that we will be able to finance our obligations under the Tax Receivable Agreement.

Payments under the Tax Receivable Agreement will generally be based on the tax reporting positions that we determine. We will not be reimbursed for any cash payments previously made to the Founders pursuant to the Tax Receivable Agreement if any tax benefits initially claimed by us are subsequently challenged by a taxing authority and ultimately disallowed. Instead, any excess cash payments made by us to a Founder will be netted against any future cash payments we might otherwise be required to make under the terms of the Tax Receivable Agreement to such Founder, as applicable. However, a challenge to any tax benefits initially claimed by us may not arise for a number of years following the initial time of such payment or, even if challenged early, such excess cash payment may be greater than the amount of future cash payments we might otherwise be required to make under the terms of the Tax Receivable Agreement and, as a result, there might not be future cash payments from which to net against. The applicable U.S. federal income tax rules are complex and factual in nature, and there can be no assurance that the IRS or a court will not disagree with our tax reporting positions. As a result, it is possible that we could make cash payments under the Tax Receivable Agreement that are substantially greater than our actual cash tax savings.

If the outcome of any audit of us or our subsidiaries is reasonably expected to adversely affect the rights and obligations of the Continuing Equity Owners under the Tax Receivable Agreement in a material respect, then we will notify the Continuing Equity Owners of such audit, keep them reasonably informed with respect thereto, provide them with a reasonable opportunity to provide information and other input concerning the audit or the relevant portion thereof and consider such information and other input in good faith.

Under the Tax Receivable Agreement, we are required to provide the Founders with a schedule showing the calculation of payments that are due under the Tax Receivable Agreement with respect to each taxable year with respect to which a payment obligation arises within 120 days after filing our U.S. federal

155

TABLE OF CONTENTS

income tax return for such taxable year. This calculation will be based upon the advice of our tax advisors. Payments under the Tax Receivable Agreement will generally be made to the Founders within five business days after this schedule becomes final pursuant to the procedures set forth in the Tax Receivable Agreement, although interest on such payments will begin to accrue at a rate of LIBOR (or similar rate) plus 1% on the date on which such calculation becomes final under the Tax Receivable Agreement. Any late payments that may be made under the Tax Receivable Agreement will continue to accrue interest at a rate equal to LIBOR (or similar rate) plus 5%, until such payments are made, generally including any late payments that we may subsequently make because we did not have enough available cash to satisfy our payment obligations at the time at which they originally arose.

Fluence Energy LLC Agreement

In connection with the consummation of the Transactions, we and the Founders will enter into Fluence Energy, LLC’s Third Amended and Restated Limited Liability Company Agreement which we refer to as the Fluence Energy LLC Agreement.

Appointment as Managing Member. Under the Fluence Energy LLC Agreement, we will become a member and the sole manager of Fluence Energy, LLC. As the sole manager, we will be able to control all the day-to-day business affairs and decision-making of Fluence Energy, LLC without the approval of any other member. As such, we, through our officers and directors, will be responsible for all operational and administrative decisions of Fluence Energy, LLC and daily management of Fluence Energy, LLC’s business. Pursuant to the terms of the Fluence Energy LLC Agreement, we cannot be removed or replaced as the sole manager of Fluence Energy, LLC except by our resignation, which may be given at any time by written notice to the members.

Compensation, Fees and Expenses. We will not be entitled to compensation for our services as the manager of Fluence Energy, LLC. We will be entitled to reimbursement by Fluence Energy, LLC for reasonable fees and expenses incurred on behalf of Fluence Energy, LLC, including all expenses associated with the Transactions, any subsequent offering of our Class A common stock, being a public company and maintaining our corporate existence.

Distributions. The Fluence Energy LLC Agreement will require “tax distributions” to be made by Fluence Energy, LLC to its members, as that term is used in the agreement, except to the extent Fluence Energy, LLC does not have available cash for such distributions or such distributions are otherwise prohibited by law or any of our future debt agreements. Tax distributions will be made on a quarterly basis, to each member of Fluence Energy, LLC, including us, based on such member’s allocable share of the taxable income of Fluence Energy, LLC and an assumed tax rate that will be determined by us, as described below. For this purpose, Fluence Energy, Inc.’s allocable share of Fluence Energy, LLC’s taxable income shall be determined without regard to any Basis Adjustments (as described above under “—Tax Receivable Agreement”). Tax distributions will generally be treated as advances of other distributions made under the Fluence Energy LLC Agreement, but no adjustments on account of prior tax distributions will be made to the redemption or exchange ratio or price for Founders whose LLC Interests are redeemed or exchanged (and tax distributions paid prior to such a redemption or exchange will not be treated as advances or otherwise reduce the distributions subsequently payable to us in respect of the LLC Interests we acquire in connection with any such redemption or exchange). The assumed tax rate for purposes of determining tax distributions from Fluence Energy, LLC to its members will generally be the highest combined marginal tax rates that may apply to a corporation that is resident in New York, New York, regardless of the actual final tax liability of Fluence Energy, LLC's members. However, in certain circumstances, including if Fluence Energy, LLC does not have sufficient cash on hand to make the entire tax distributions to the Continuing Equity Owners that would otherwise be required, the tax distributions that Fluence Energy, LLC makes to us may be reduced, without corresponding reductions to the tax distributions that Fluence Energy, LLC makes to the Continuing Equity Owners. The Fluence Energy LLC Agreement will also allow for cash distributions to be made by Fluence Energy, LLC (subject to our sole discretion as the sole manager of Fluence Energy, LLC) to its members on a pro rata basis out of “distributable cash,” as that term is defined in the agreement. We expect Fluence Energy, LLC may make distributions out of distributable cash periodically and as necessary to enable us to cover our operating expenses and other obligations, including our tax liabilities and obligations under the Tax Receivable Agreement, except to the extent Fluence Energy, LLC is insolvent or are otherwise prohibited by law or any of our future debt agreements.

TABLE OF CONTENTS

Transfer Restrictions. The Fluence Energy LLC Agreement generally does not permit transfers of LLC Interests by members, except for transfers whereby AES Grid Stability or Siemens Industry transfers all (but not less than all) of its respective LLC Interests to any party (other than certain restricted parties), transfers pursuant to the redemption right described below, transfers to affiliates and transfers approved in writing by us, as manager, and other limited exceptions. The Fluence Energy LLC Agreement may impose additional restrictions on transfers (including redemptions described below with respect to each common unit) that are necessary or advisable so that Fluence Energy, LLC is not treated as a “publicly traded partnership” for U.S. federal income tax purposes. In the event of a permitted transfer under the Fluence Energy LLC Agreement, such member will be required to simultaneously transfer shares of Class B-1 common stock or Class B-2 common stock, as the case may be, to such transferee equal to the number of LLC Interests that were transferred to such transferee in such permitted transfer.

The Fluence Energy LLC Agreement provides that, in the event that a tender offer, share exchange offer, issuer bid, take-over bid, recapitalization or similar transaction with respect to our Class A common stock, each of which we refer to as a “Pubco Offer,” is approved by our board of directors or otherwise effected or to be effected with the consent or approval of our board of directors, each holder of LLC Interests shall be permitted, but not required, to participate in such Pubco Offer by delivering a redemption notice, which shall be effective immediately prior to, and contingent upon, the consummation of such Pubco Offer. If a Pubco Offer is proposed by Fluence Energy, Inc., then Fluence Energy, Inc. is required to use its reasonable best efforts expeditiously and in good faith to take all such actions and do all such things as are necessary or desirable to enable and permit the holders of such LLC Interests to participate in such Pubco Offer, if they so elect, to the same extent as or on an economically equivalent basis with the holders of shares of Class A common stock, provided that in no event shall any holder of LLC Interests be entitled to receive aggregate consideration for each common unit that is greater than the consideration payable in respect of each share of Class A common stock pursuant to the Pubco Offer.

Except for certain exceptions, any transferee of LLC Interests must assume, by operation of law or executing a joinder to the Fluence Energy LLC Agreement, all of the obligations of a transferring member with respect to the transferred units, and such transferee shall be bound by any limitations and obligations under the Fluence Energy LLC Agreement even if the transferee is not admitted as a member of Fluence Energy, LLC. A member shall remain as a member with all rights and obligations until the transferee is accepted as substitute member in accordance with the Fluence Energy LLC Agreement.

Recapitalization. The Fluence Energy LLC Agreement will recapitalize the units currently held by the existing members of Fluence Energy, LLC into a new single class of LLC Interests. The Fluence Energy LLC Agreement will also reflect a split of LLC Interests such that one common unit can be acquired with the net proceeds received in the initial offering from the sale of one share of our Class A common stock, after the deduction of the underwriting discount and estimated offering expenses payable by us. Each common unit generally will entitle the holder to a pro rata share of the net profits and net losses and distributions of Fluence Energy, LLC, although for income tax purposes, items of taxable income, gain, loss or deduction may be allocated disproportionately under applicable law to account for built-in gains or built-in losses that existed at the time of this offering or certain other extraordinary transactions.

Maintenance of One-to-one Ratio between Shares of Class A Common Stock and LLC Interests Owned by the Company, and One-to-one Ratio between Shares of Class B-1 and Class B-2 common stock and LLC Interests Owned by the Founders. Except as otherwise determined by us, the Fluence Energy LLC Agreement requires Fluence Energy, LLC to take all actions with respect to its LLC Interests, including issuances, reclassifications, distributions, divisions or recapitalizations, such that (1) we at all times maintain a ratio of one common unit owned by us, directly or indirectly, for each share of Class A common stock issued and outstanding, and (2) Fluence Energy, LLC at all times maintains (a) a one-to-one ratio between the number of shares of Class A common stock issued and outstanding and the number of LLC Interests owned by us and (b) a one-to-one ratio between the aggregate number of shares of Class B-1 and Class B-2 common stock issued and outstanding and the number of LLC Interests owned by the Founders and their permitted transferees, collectively. This ratio requirement disregards (1) shares of our Class A common stock under unvested options issued by us, (2) treasury stock, and (3) preferred stock or other debt or equity securities (including warrants, options or rights) issued by us that are convertible into or exercisable or exchangeable for shares of Class A common stock, except to the extent we have contributed the net proceeds from such

157

TABLE OF CONTENTS

other securities, including any exercise or purchase price payable upon conversion, exercise or exchange thereof, to the equity capital of Fluence Energy, LLC. In addition, the Class A common stock ratio requirement disregards all LLC Interests at any time held by any other person, including the Founders and the holders of options over LLC Interests. If we issue, transfer or deliver from treasury stock or repurchase shares of Class A common stock in a transaction not contemplated by the Fluence Energy LLC Agreement, we as manager of Fluence Energy, LLC have the authority to take all actions such that, after giving effect to all such issuances, transfers, deliveries or repurchases, the number of outstanding LLC Interests we own equals, on a one-for-one basis, the number of outstanding shares of Class A common stock. If we issue, transfer or deliver from treasury stock or repurchase or redeem any of our preferred stock in a transaction not contemplated by the Fluence Energy LLC Agreement, we as manager have the authority to take all actions such that, after giving effect to all such issuances, transfers, deliveries repurchases or redemptions, we hold (in the case of any issuance, transfer or delivery) or cease to hold (in the case of any repurchase or redemption) equity interests in Fluence Energy, LLC which (in our good faith determination) are in the aggregate substantially equivalent to our preferred stock so issued, transferred, delivered, repurchased or redeemed. Fluence Energy, LLC is prohibited from undertaking any subdivision (by any split of units, distribution of units, reclassification, recapitalization or similar event) or combination (by reverse split of units, reclassification, recapitalization or similar event) of the LLC Interests that is not accompanied by an identical subdivision or combination of (1) our Class A common stock to maintain at all times a one-to-one ratio between the number of LLC Interests owned by us and the number of outstanding shares of our Class A common stock and (2) our Class B-1 and Class B-2 common stock to maintain at all times a one-to-one ratio between the number of LLC Interests owned by the Founders and the aggregate number of outstanding shares of our Class B-1 and Class B-2 common stock, as applicable, in each case, subject to exceptions.

Issuance of LLC Interests upon Exercise of Options or Issuance of Other Equity Compensation. Upon the exercise of options issued by us (as opposed to options issued by Fluence Energy, LLC), or the issuance of other types of equity compensation by us (such as the issuance of restricted or non-restricted stock, payment of bonuses in stock or settlement of stock appreciation rights in stock), we will have the right to acquire from Fluence Energy, LLC a number of LLC Interests equal to the number of our shares of Class A common stock being issued in connection with the exercise of such options or issuance of other types of equity compensation. When we issue shares of Class A common stock in settlement of stock options granted to persons that are not officers or employees of Fluence Energy, LLC or its subsidiaries, we will make, or be deemed to make, a capital contribution in Fluence Energy, LLC equal to the aggregate value of such shares of Class A common stock and Fluence Energy, LLC will issue to us a number of LLC Interests equal to the number of shares we issued. When we issue shares of Class A common stock in settlement of stock options granted to persons that are officers or employees of Fluence Energy, LLC or its subsidiaries, then we will be deemed to have sold directly to the person exercising such award a portion of the value of each share of Class A common stock equal to the exercise price per share, and we will be deemed to have sold directly to Fluence Energy, LLC (or the applicable subsidiary of Fluence Energy, LLC) the difference between the exercise price and market price per share for each such share of Class A common stock. In cases where we grant other types of equity compensation to employees of Fluence Energy, LLC or its subsidiaries, on each applicable vesting date we will be deemed to have sold to Fluence Energy, LLC (or such subsidiary) the number of vested shares at a price equal to the market price per share, Fluence Energy, LLC (or such subsidiary) will deliver the shares to the applicable person, and we will be deemed to have made a capital contribution in Fluence Energy, LLC equal to the purchase price for such shares in exchange for an equal number of LLC Interests.

Dissolution. The Fluence Energy LLC Agreement will provide that the consent of Fluence Energy, Inc. as the managing member of Fluence Energy, LLC and members holding a majority of the voting units will be required to voluntarily dissolve Fluence Energy, LLC. In addition to a voluntary dissolution, Fluence Energy, LLC will be dissolved upon the entry of a decree of judicial dissolution or other circumstances in accordance with Delaware law. Upon a dissolution event, the proceeds of a liquidation will be distributed in the following order: (1) first, to pay the expenses of winding up Fluence Energy, LLC; (2) second, to pay debts and liabilities owed to creditors of Fluence Energy, LLC, other than members; and (3) third, to the members pro-rata in accordance with their respective percentage ownership interests in Fluence Energy, LLC (as determined based on the number of LLC Interests held by a member relative to the aggregate number of all outstanding LLC Interests).

158

TABLE OF CONTENTS

Confidentiality. We, as manager, and each member agree to maintain the confidentiality of Fluence Energy, LLC’s confidential information. This obligation excludes information independently obtained or developed by the members, information that is in the public domain or otherwise disclosed to a member, in either such case not in violation of a confidentiality obligation of the Fluence Energy LLC Agreement or approved for release by written authorization of the Chief Executive Officer, the Chief Financial Officer or the General Counsel of either Fluence Energy, Inc. or Fluence Energy, LLC.

Indemnification. The Fluence Energy LLC Agreement will provide for indemnification of the manager, members and officers of Fluence Energy, LLC and their respective subsidiaries or affiliates.

Common Unit Redemption Right. The Fluence Energy LLC Agreement will provide a redemption right to the Founders which will entitle them to have their LLC Interests redeemed for, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), newly-issued shares of our Class A common stock on a one-for-one basis or a cash payment from the sale of newly issued shares of Class A common stock equal to a volume weighted average market price of one share of Class A common stock for each LLC interest so redeemed, in each case in accordance with the terms of the Fluence Energy LLC Agreement; provided that, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), we may effect a direct exchange by Fluence Energy, Inc. of such Class A common stock or such cash, as applicable, for such LLC Interests. Such Founders may exercise such redemption right, subject to certain exceptions, for as long as their LLC Interests remain outstanding. In connection with the exercise of the redemption or exchange of LLC Interests (1) such Founders will be required to surrender a number of shares of our Class B-1 common stock or Class B-2 common stock, as the case may be, registered in the name of such redeeming or exchanging Founder, which will automatically be transferred to the Company and will be canceled for no consideration on a one-for-one basis with the number of LLC Interests so redeemed or exchanged and (2) except in the case of a direct exchange as described above, the redeeming Founders will surrender LLC Interests to Fluence Energy, LLC for cancellation. In the event of cash settlement, Fluence Energy, Inc. would issue new shares of Class A common stock and use the proceeds from the sale of these newly-issued shares of Class A common stock to fully fund the cash settlement, which, in effect, limits the amount of the cash payment to the redeeming member.

Each Founder’s redemption rights will be subject to certain customary limitations, including the absence of any liens or encumbrances on such LLC Interests redeemed. Additionally, in the case we elect a cash settlement, such Founder may rescind its redemption request within a specified period of time. Moreover, in the case of a settlement in Class A common stock, such Founder’s redemption may be conditioned on the consummation of a purchase by another person (whether in a tender or exchange offer, an underwritten offering or otherwise) of the shares of Class A common stock that may be issued in connection with such proposed redemption. In the case of a settlement in Class A common stock, such Founder may also revoke or delay its redemption request if the following conditions exist: (1) any registration statement pursuant to which the resale of the Class A common stock to be registered for such Founder at or immediately following the consummation of the redemption shall have ceased to be effective pursuant to any action or inaction by the SEC or no such resale registration statement has yet become effective; (2) we failed to cause any related prospectus to be supplemented by any required prospectus supplement necessary to effect such redemption; (3) we exercised our right to defer, delay or suspend the filing or effectiveness of a registration statement and such deferral, delay or suspension shall affect the ability of such Founder to have its Class A common stock registered at or immediately following the consummation of the redemption; (4) such Founder is in possession of any material non-public information concerning us, the receipt of which results in such Founder being prohibited or restricted from selling Class A common stock at or immediately following the redemption without disclosure of such information (and we do not permit disclosure); (5) any stop order relating to the registration statement pursuant to which the Class A common stock was to be registered by such Founder at or immediately following the redemption shall have been issued by the SEC; (6) there shall have occurred a material disruption in the securities markets generally or in the market or markets in which the Class A common stock is then traded; (7) there shall be in effect an injunction, a restraining order or a decree of any nature of any governmental entity that restrains or prohibits the redemption; (8) we shall have failed to comply in all material respects with our obligations under the Registration Rights Agreement, and such failure shall have affected the ability of such Founder to consummate the resale of the

159

TABLE OF CONTENTS

Class A common stock to be received upon such redemption pursuant to an effective registration statement; or (9) the redemption date would occur three business days or less prior to, or during, a black-out period.

The Fluence Energy LLC Agreement will require that in the case of a redemption by a Founder we contribute cash or shares of our Class A common stock, as applicable, to Fluence Energy, LLC in exchange for an amount of newly-issued LLC Interests that will be issued to us equal to the number of LLC Interests redeemed from the Founder. Fluence Energy, LLC will then distribute the cash or shares of our Class A common stock, as applicable, to such Founder to complete the redemption. Alternatively, we may, at our option, effect a direct exchange by Fluence Energy, Inc. of cash or our Class A common stock, as applicable, for such LLC Interests in lieu of such a redemption. Whether by redemption or exchange, we are obligated to ensure that at all times the number of LLC Interests that we own equals the number of our outstanding shares of Class A common stock (subject to certain exceptions for treasury shares and shares underlying certain convertible or exchangeable securities).

Change of Control Redemption. In the event of certain types of change of control described in the Fluence Energy, LLC Agreement, Fluence Energy, Inc. will have the right, in its sole discretion, to require each member to effect a redemption of all or a portion of such member's and all other member’s LLC Interests (including common units or any other type, class or series of interests in Fluence Energy, LLC) together with an equal number of shares of Class B common stock; provided, however, that neither AES Grid Stability nor Siemens Industry will be required to effect such a redemption if such member holds at least 15% of the aggregate LLC Interests issued and outstanding. In connection with such redemption, such LLC Interests and such shares of Class B common stock will be exchanged for shares of Class A common stock (or an economically equivalent amount of cash and securities of a successor entity that would be received by holders of shares of Class A common stock).

Amendments. In addition to certain other requirements, our consent, as manager, and the consent of members holding a majority of the LLC Interests then outstanding and entitled to vote (excluding LLC Interests held directly or indirectly by us) will generally be required to amend or modify the Fluence Energy LLC Agreement.

Stockholders Agreement

Pursuant to the Stockholders Agreement we and the Continuing Equity Owners will enter into in connection with the consummation of the Transactions, (a) each of AES Grid Stability and Siemens Industry will initially have the right to nominate three of our directors, which shall be reduced to two directors for as long as they shall directly or indirectly, beneficially own, in the aggregate, less than 20% but 10% or more of our Class A common stock (assuming that all outstanding LLC Interests in Fluence Energy, LLC (other than LLC Interests held by us) are redeemed for newly issued shares of our Class A common stock on a one-for-one basis), and which shall further be reduced to one director for as long as they shall directly or indirectly, beneficially own, in the aggregate, less than 10% but 5% or more of our Class A common stock (assuming that all outstanding LLC Interests in Fluence Energy, LLC (other than LLC Interests held by us) are redeemed for newly issued shares of our Class A common stock on a one-for-one basis), no Directors if they shall directly or indirectly, beneficially own, in the aggregate, less than 5% of our Class A common stock (assuming that all outstanding LLC Interests in Fluence Energy, LLC (other than LLC Interests held by us) are redeemed for newly issued shares of our Class A common stock on a one-for-one basis), and (b) the Blocker Shareholder will have the right to nominate one of our Directors if they shall directly or indirectly, beneficially own, in the aggregate, at least 5% of our Class A common stock (assuming that all outstanding LLC Interests in Fluence Energy, LLC (other than LLC Interests held by us) are redeemed for newly issued shares of our Class A common stock on a one-for-one basis).

Each of AES Grid Stability, Siemens Industry, and the Blocker Shareholder will also agree to vote, or cause to vote, all of their outstanding shares of our Class A common stock, Class B-1 common stock and Class B-2 common stock at any annual or special meeting of stockholders in which directors are elected, so as to cause the election of the Directors nominated by the other Continuing Equity Owners.

In addition, the Stockholders Agreement provides the Blocker Shareholder with certain “tag along” rights to participate in certain sales of shares and LLC Interests by AES Grid Stability and Siemens Industry. The Stockholders Agreement provides that (x) if either AES Grid Stability or Siemens Industry individually sells 100% of their shares of Class A common Stock, Class B-2 common stock and/or LLC Interests to an unrelated third party (the “Sale Shares”) and (y) the Sale Shares represent 20% or more of all the issued and outstanding shares of Class A common stock (assuming conversion of all outstanding underlying LLC Interests into shares of Class A common stock), then AES Grid Stability or Siemens Industry may sell the Sale Shares and if such party seeks to assign such party’s rights under the Stockholders Agreement to the buyer, Blocker Shareholder shall have the right to participate in the sale of such Sale Shares and sell 100% of Blocker Shareholder’s shares of Class A common stock in connection therewith. In the event (x) AES Grid Stability and Siemens Industry collectively sell Sale Shares and (y) such Sale Shares represent 30% or more of all the issued and outstanding shares of Class A common stock (assuming conversion of all outstanding underlying LLC Interests into shares of Class A common stock), then if (1) (i) AES Grid Stability and Siemens Industry sell 100% of their collective Sale Shares, then (ii) Blocker Shareholder shall have the right to sell to such third party 100% of its shares of Class A common stock or (2) (i) if AES Grid Stability and Siemens Industry sell less than 100% of their Sale Shares, then (ii) Blocker Shareholder shall have the right to sell to such third party a pro rata share of its shares of its Class A common stock.

TABLE OF CONTENTS

In addition, the Stockholders Agreement provides that, notwithstanding the tag-along rights described above, in the event that AES Grid Stability and Siemens Industry collectively sell to a third party 100% of the Class A common Stock, Class B-2 common Stock and LLC Interests they each own (a “Drag-Along Transaction”) and (A) as a result of such Drag-Along Transaction, such third party acquires at least 60% (in the aggregate) of the issued and outstanding shares of Class A common stock (assuming consummation of the underlying LLC Interests into shares of Class A common stock) and (B) the purchase price set forth in the bona fide offer from the third party purchaser is at least a 30% increase on 30-day average trading price for the shares of Class A common stock and LLC (a “Drag Offer”), then AES Grid Stability and Siemens Industry may, at their option, require the Blocker Shareholder to sell 100% of their shares of Class A common stock to the third party by giving written notice to the Blocker Shareholder not less than 30 days prior to the date stated in the Drag Offer for consummation of the sale contemplated by the Drag Offer.

The Stockholders Agreement will terminate upon the earliest to occur of (i) the Continuing Equity Owners ceasing to beneficially own, directly or indirectly, any shares of Class A common stock (assuming that all outstanding LLC Interests in Fluence Energy, LLC (other than LLC Interests held by us) are redeemed for newly issued shares of our Class A common stock on a one-for-one basis), (ii) the Continuing Equity Owners ceasing to have any director designation rights under the Stockholders Agreement and (iii) as unanimously agreed between us and the Continuing Equity Owners. In addition, the Stockholders Agreement will terminate (i) as to each of AES Grid Stability and Siemens Industry upon the AES Grid Stability or Siemens Industry related parties, respectively, ceasing to beneficially own, directly or indirectly, any Class A common stock (assuming that all outstanding LLC Interests in Fluence Energy, LLC (other than LLC Interests held by us) are redeemed for newly issued shares of our class A common stock on a one-for-one basis) and (ii) solely as to the Blocker Shareholder, at its sole discretion, upon (A) (x) the Board no longer having a Blocker Shareholder director and (y) the Blocker Shareholder owning, directly or indirectly, less than 5% of all issued and outstanding shares of Class A common stock (assuming that all outstanding LLC Interests in Fluence Energy, LLC (other than LLC Interests held by us) are redeemed for newly issued shares of our class A common stock on a one-for-one basis) or (B) following a transfer by either AES Grid Stability or Siemens Industry of common stock or LLC Interests and the right to designate a director to an unaffiliated third party, in the event the Blocker Shareholder determines that it would not be able to vote for a director candidate nominated by such third party transferee.

The Stockholders Agreement may not be assigned without the express prior written consent of the other parties thereto; provided, however, that each of AES Grid Stability, Siemens Industry and Blocker Shareholder is permitted to assign to their respective permitted transferees under the Stockholders Agreement (so long as any such permitted transferee becomes a party to the Stockholders Agreement); and provided further, that each of AES Grid Stability, Siemens Industry and Blocker Shareholder is permitted, without the consent of any party, to assign its rights and obligations under the Stockholders Agreement to a transferee of all (but not less than all) of its respective Class A common stock, Class B-1 common stock, Class B-2 common stock and/or LLC Units (as applicable) in a transfer not prohibited by the LLC Agreement, so long as such transferee agrees to become party to, and be bound by all of the provisions of the Stockholders Agreement.

Equity Owners with “demand” registration rights whereby they can require us to register under the Securities Act the offer and sale of shares of Class A common stock issuable to them, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), upon redemption or exchange of their LLC Interests.

Intellectual Property License Agreements

On June 9, 2021, we entered into amended and restated intellectual property license agreement with Siemens pursuant to which Siemens entities will grant worldwide, non-exclusive, non-transferable, perpetual, royalty-free license to conduct certain non-exclusive activities for certain permitted business purposes and to engage in permitted sublicensing thereunder, subject to various exceptions. Similarly, we granted Siemens perpetual, non-exclusive, worldwide rights to do any acts within the current and future fields of business of Siemens or Siemens Industry, which are not activities which are exclusive to us and which would otherwise infringe any of the contributed Siemens intellectual property under fair, reasonable and non-discriminatory royalty terms, to be negotiated by the parties thereto before the licenses are exercised. The license agreement contains customary indemnification and limitation of liability provisions. Neither party will be permitted to assign their rights or obligations without the consent of the other party thereto.

Equipment and Services Purchase Agreement

In connection with the consummation of this offering, we will enter into an amended and restated equipment and services purchase agreement with Siemens Industry pursuant to which Siemens Industry will supply electrical balance of plant equipment and related services to us under preferred purchasing conditions.

Storage Core Frame Purchase Agreements

In connection with the consummation of this offering, we will enter into an amended and restated storage core frame purchase agreement with each of AES Grid Stability and Siemens Industry, pursuant to which AES Grid Stability and Siemens Industry, purchase energy storage equipment and related services from us under preferred purchasing conditions, including most-favored-nation pricing, either for use in their own electrical transmission and distribution projects or for resale to their own end-customers. The storage core frame purchase agreements will contain customary provisions regarding orders and payment, delivery, title and risk of loss, quality control, warranties, force majeure, intellectual property, indemnification, confidentiality and dispute resolution, among others. The term of these agreements shall commence on the effective date and shall continue until the earlier of the (x) seven year anniversary thereof and (y) the date on which AES Grid Stability or Siemens Industry, as applicable, hold less than 10% of the then outstanding voting power. If AES Grid Stability and Siemens Industry hold at least 20% of the then-outstanding voting power, they shall cause their business units to purchase certain of our product offerings exclusively from us. If AES Grid Stability and Siemens Industry hold at least 10% of the then-outstanding voting power, neither it or its affiliates will directly or indirectly engage in any of the defined exclusive activities set forth in the agreement, subject to us maintaining certain sales volume requirements. Upon transfer of title with respect to any equipment purchased thereunder, we will grant such affiliate a non-exclusive, transferable, fully paid-up with no further royalty obligations, worldwide license in all intellectual property owed or licensed by us which are necessary for their use and enjoyment of such equipment. Neither party will be permitted to assign their rights or obligations, other than to an affiliate, without the written consent of the other party thereto, which consent shall not be unreasonably withheld. If any dispute arises regarding payments, either party shall pay all undisputed amounts, and both parties shall attempt in good faith to resolve the dispute as promptly as practicable. If parties are unable to resolve a dispute within 30 days, then either party may submit the dispute to arbitration.

Master Sales Cooperation Agreement

Siemens Industry, Inc. and Fluence Energy, LLC previously entered into a master sales cooperation agreement on January 1, 2018 for the intent of cooperating to ensure meeting customer demands, timely

164

TABLE OF CONTENTS

delivery of high-quality battery energy storage solutions and related service and effective order planning and processing. The parties agree that the initial master sales cooperation agreement is terminated effective as of the date of the signing of the new master sales cooperation agreement and that this agreement replaces the initial agreement. In order to accelerate the adoption of energy storage in the market and to leverage Siemens’ extensive sales reach, Fluence is using Siemens sales organizations and customer relationships in some countries to bring Fluence’s battery energy storage solutions to Siemens customers as well as working together to assist Siemens in offering battery energy storage solutions as part of a larger solution. Both parties intend to cooperate and deliver value to each of the parties’ customers. Siemens intends to support Fluence in a potential usage of the Siemens sales organization worldwide. The support that Siemens can provide will be defined by a country specific agreement and/or project related agreements. The decision to pursue any specific project or transactions under any of the agreements shall be made independently and at the sole discretion of the parties. The cooperation activities are non-exclusive, neither party shall have grounds for any claim under any theory of law against the other party as it relates to this agreement, modifications shall only be valid if made in writing, and the agreement will continue in effect until December 31, 2022 and automatically extend by consecutive one-year intervals unless terminated by a party upon three months prior written notice to the other party.

Director and Officer Indemnification and Insurance

Prior to the consummation of this offering, we intend to enter into separate indemnification agreements with each of our directors and executive officers. We have also purchased directors’ and officers’ liability insurance. See “Description of Capital Stock—Limitations on Liability and Indemnification of Officers and Directors.”

Directed Share Program

At our request, the underwriters have reserved for sale at the initial public offering price per share up to 5.0% of the shares of Class A common stock offered by this prospectus for sale at the initial public offering price through a directed share program to certain individuals identified by management. See the section titled “Underwriting—Directed Share Program.”

Our Policy Regarding Related Party Transactions

Our board of directors will adopt a written related person transaction policy, to be effective upon the closing of this offering, setting forth the policies and procedures for the review and approval or ratification by our audit committee of related person transactions. This policy will cover, with certain exceptions set forth in Item 404 of Regulation S-K under the Securities Act, any transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, in which we were or are to be a participant, where the amount involved exceeds $120,000 in any fiscal year and a related person had, has or will have a direct or indirect material interest, including without limitation, purchases of goods or services by or from the related person or entities in which the related person has a material interest, indebtedness, guarantees of indebtedness, and employment by us of a related person. In reviewing and approving any such transactions, our audit committee is tasked to consider all relevant facts and circumstances, including, but not limited to, whether the transaction is on terms comparable to those that could be obtained in an arm’s length transaction and the extent of the related person’s interest in the transaction. All of the transactions described in this section occurred prior to the adoption of this policy.

TABLE OF CONTENTS

PRINCIPAL STOCKHOLDERS

The following table sets forth information with respect to the beneficial ownership of our common stock (1) immediately following the consummation of the Transactions (excluding this offering), as described in “Our Organizational Structure” and (2) as adjusted to give effect to this offering, for:

•

each person known by us to beneficially own more than 5% of our Class A common stock or our Class B-1 or Class B-2 common stock;

•

each of our directors;

•

each of our named executive officers; and

•

all of our executive officers and directors as a group.

As described in “Our Organizational Structure” and “Certain Relationships and Related Party Transactions,” each common unit (other than LLC Interests held by us) is redeemable from time to time at each holder’s option for, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), newly-issued shares of our Class A common stock on a one-for-one basis or a cash payment equal to a volume weighted average market price of one share of Class A common stock for each LLC Interest so redeemed, in each case, in accordance with the terms of the Fluence Energy LLC Agreement; provided that, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), we may effect a direct exchange by Fluence Energy, Inc. of such Class A common stock or such cash, as applicable, for such LLC Interests. The Founders may, subject to certain exceptions, exercise such redemption right for as long as their LLC Interests remain outstanding. See “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement.” In connection with this offering, we will issue to the Founders, for nominal consideration, one share of Class B-1 common stock for each common unit of Fluence Energy, LLC such Founder will own, respectively. As a result, the number of shares of Class B-1 common stock listed in the table below correlates to the number of LLC Interests the Founders will own immediately after the Transactions. Although the number of shares of Class A common stock being offered hereby to the public and the total number of LLC Interests outstanding after the offering will remain fixed regardless of the initial public offering price in this offering, the shares of Class B-1 common stock held by the beneficial owners set forth in the table below after the consummation of the Transactions will vary, depending on the initial public offering price in this offering. The table below assumes the shares of Class A common stock are offered at $22.50 per share (the midpoint of the estimated price range set forth on the cover page of this prospectus). See “Our Organizational Structure.”

The number of shares beneficially owned by each stockholder as described in this prospectus is determined under rules issued by the SEC. Under these rules, beneficial ownership includes any shares as to which the individual or entity has sole or shared voting power or investment power. In computing the number of shares beneficially owned by an individual or entity and the percentage ownership of that person, shares of common stock subject to options, or other rights, including the redemption right described above with respect to each common unit, held by such person that are currently exercisable or will become exercisable within 60 days of September 30, 2021, are considered outstanding, although these shares are not considered outstanding for purposes of computing the percentage ownership of any other person. The percentage ownership of each individual or entity after giving effect to the Transactions and before this offering is computed on the basis of 18,493,275 shares of our Class A common stock outstanding and 117,173,390 shares of our Class B-1 common stock outstanding. The percentage ownership of each individual or entity after the offering is computed on the basis of 49,493,275 shares of our Class A common stock outstanding and 117,173,390 shares of our Class B-1 common stock outstanding. Percentage ownership of our common stock after this offering also assumes the sale by us and the selling stockholder of shares of our Class A common stock in this offering. No shares of Class B-2 common stock will be outstanding immediately after the Transactions and before or after the offering. The table below excludes any purchases that may be made through our directed share program or otherwise in this offering. See “Underwriting—Directed Share Program.” Unless otherwise indicated, the address of all listed stockholders is c/o Fluence Energy, Inc., 4601 Fairfax Drive, Suite 600, Arlington, Virginia 22203.

Each of the stockholders listed has sole voting and investment power with respect to the shares beneficially owned by the stockholder unless noted otherwise, subject to community property laws where applicable.

(1)

Each common unit is redeemable from time to time at each holder’s option for, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), newly-issued shares of our Class A common stock on a one-for-one basis or a cash payment equal to a volume weighted average market price of one share of Class A common stock for each LLC Interest so redeemed, in each case, in accordance with the terms of the Fluence Energy LLC Agreement; provided that, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), we may effect a direct exchange by Fluence Energy, Inc. of such Class A common stock or such cash, as applicable, for such LLC Interests. The Founders may, subject to certain exceptions, exercise such redemption right for as long as their LLC Interests remain outstanding. See “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement.” In these tables, beneficial ownership of LLC Interests has been reflected as beneficial ownership of shares of our Class A common stock for which such LLC Interests may be exchanged.

(2)

Each share of Class A common stock entitles the registered holder to one vote per share and each share of Class B-1 common stock entitles the registered holder thereof to five votes per share on all matters presented to stockholders for a vote generally, including the election of directors. The Class A common stock and Class B-1 common stock will vote as a single class on all matters except as required by law or our amended and restated certificate of incorporation.

Class B-1 and Class B-2 Common Stock

Each share of our Class B-1 common stock entitles its holders to five votes per share and each share of our Class B-2 common stock entitles its holders to one vote per share on all matters presented to our stockholders generally.

Shares of Class B-1 and Class B-2 common stock will be issued in the future only (a) to the extent necessary to maintain a one-to-one ratio between the number of LLC Interests held by the Founders and the aggregate number of shares of Class B-1 and Class B-2 common stock issued to the Founders, and (b) in

168

TABLE OF CONTENTS

the case of Class B-2 common stock, upon conversion of Class B-1 common stock as described below. Shares of Class B-1 and Class B-2 common stock are transferable only together with an equal number of LLC Interests. Only permitted transferees of LLC Interests held by the Founders will be permitted transferees of Class B-1 and Class B-2 common stock. See “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement.”

Holders of shares of our Class B-1 and Class B-2 common stock will vote together with holders of our Class A common stock as a single class on all matters presented to our stockholders for their vote or approval, except for certain amendments to our amended and restated certificate of incorporation described below or as otherwise required by applicable law or the amended and restated certificate of incorporation.

Holders of our Class B-1 and Class B-2 common stock do not have any right to receive dividends or to receive a distribution upon dissolution or liquidation. Additionally, holders of shares of our Class B-1 and Class B-2 common stock do not have preemptive, subscription, redemption or conversion rights. There will be no redemption or sinking fund provisions applicable to the Class B-1 or Class B-2 common stock. Any amendment of our amended and restated certificate of incorporation that gives holders of our Class B-1 or Class B-2 common stock (1) any rights to receive dividends or any other kind of distribution, (2) any right to convert into or be exchanged for Class A common stock or (3) any other economic rights will require, in addition to stockholder approval, the affirmative vote of holders of our Class A common stock voting separately as a class.

Each outstanding share of Class B-1 common stock will automatically convert into one share of Class B-2 common stock upon the earliest of (1) any transfer by a Founder of such shares of Class B-1 common stock other than to an affiliate of such Founder, (2) with respect to each Founder and its affiliates, 5:00 p.m. (New York City time) on a date fixed by our board of directors that is not less than 60 days nor more than 180 days following the date that such Founder, together with its affiliates, ceases to hold an aggregate number of shares of all classes of our common stock representing at least 20% of the aggregate number of all outstanding shares of all classes of our common stock, and (3) 5:00 p.m. (New York City time) on the date that is seven years following the closing of the offering.

Upon the consummation of the Transactions, the Founders will together own 100% of the outstanding shares of our Class B-1 common stock. Upon the consummation of the Transactions, no shares of our Class B-2 common stock will be outstanding.

Preferred Stock

Upon the consummation of the Transactions and the effectiveness of our amended and restated certificate of incorporation that will become effective immediately prior to the consummation of the Transactions, the total of our authorized shares of preferred stock will be 10,000,000 shares. Upon the consummation of the Transactions, we will have no shares of preferred stock outstanding.

Under the terms of our amended and restated certificate of incorporation that will become effective immediately prior to the consummation of the Transactions, our board of directors is authorized to direct us to issue shares of preferred stock in one or more series without stockholder approval. Our board of directors has the discretion to determine the rights, preferences, privileges, and restrictions, including voting rights, dividend rights, conversion rights, redemption privileges, and liquidation preferences, of each series of preferred stock.

The purpose of authorizing our board of directors to issue preferred stock and determine its rights and preferences is to eliminate delays associated with a stockholder vote on specific issuances. The issuance of preferred stock, while providing flexibility in connection with possible acquisitions, future financings, and other corporate purposes, could have the effect of making it more difficult for a third party to acquire, or could discourage a third party from seeking to acquire, a majority of our outstanding voting stock. Additionally, the issuance of preferred stock may adversely affect the holders of our Class A common stock by restricting dividends on the Class A common stock, diluting the voting power of the Class A common stock or subordinating the liquidation rights of the Class A common stock. As a result of these or other factors, the issuance of preferred stock could have an adverse impact on the market price of our Class A common stock.

Registration Rights

We intend to enter into a Registration Rights Agreement with the Continuing Equity Owners in connection with this offering pursuant to which such parties will have specified rights to require us to register for resale all or a portion of their shares of Class A common stock under the Securities Act. See “Certain Relationships and Related Party Transactions—Registration Rights Agreement.”

Forum Selection

Our amended and restated certificate of incorporation will provide (A) (i) any derivative action or proceeding brought on behalf of the Company, (ii) any action asserting a claim for or based on breach of a fiduciary duty owed by any current or former director, officer, other employee, agent or stockholder of the Company to the Company or the Company’s stockholders, (iii) any action asserting a claim against the Company or any current or former director, officer, employee, agent or stockholder of the Company arising pursuant to any provision of the DGCL, our amended and restated certificate of incorporation or our amended and restated bylaws (as either may be amended or restated) or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware or (iv) any action asserting a claim related to or involving the Company that is governed by the internal affairs doctrine of the law of the State of Delaware shall, to the fullest extent permitted by law, be exclusively brought in the Court of Chancery of the State of Delaware or, if such court does not have subject matter jurisdiction thereof, the federal district court of the State of Delaware; and (B) the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act. Notwithstanding the foregoing, the exclusive forum provision shall not apply to claims seeking to enforce any liability or duty created by the Exchange Act.

Dividends

Declaration and payment of any dividend will be subject to the discretion of our board of directors. The time and amount of dividends will be dependent upon our business prospects, results of operations, financial condition, cash requirements and availability, debt repayment obligations, capital expenditure needs, contractual restrictions, covenants in the agreements governing our future indebtedness, industry trends, the provisions of Delaware law affecting the payment of distributions to stockholders, and any other factors our board of directors may consider relevant. We currently intend to retain all available funds and any future earnings to fund the development and growth of our business, and therefore, do not anticipate declaring or paying any cash dividends on our Class A common stock in the foreseeable future. See “Dividend Policy” and “Risk Factors—Risks related to the offering and ownership of our Class A common stock—Because we have no current plans to pay regular cash dividends on our Class A common stock following this offering, you may not receive any return on investment unless you sell your Class A common stock for a price greater than that which you paid for it.”

Anti-Takeover Provisions

Our amended and restated certificate of incorporation and amended and restated bylaws, as they will be in effect immediately prior to the consummation of the Transactions, will contain provisions that may delay, defer or discourage another party from acquiring control of us. We expect that these provisions, which are summarized below, will discourage coercive takeover practices or inadequate takeover bids. These provisions are also designed to encourage persons seeking to acquire control of us to first negotiate with our board of directors, which we believe may result in an improvement of the terms of any such acquisition in favor of our stockholders. However, they also give our board of directors the power to discourage acquisitions that some stockholders may favor.

Authorized but Unissued Shares

The authorized but unissued shares of our common stock and our preferred stock are available for future issuance without stockholder approval, subject to any limitations imposed by the Nasdaq rules. These additional shares may be used for a variety of corporate finance transactions, acquisitions and employee benefit plans and, as described under “Certain Relationships and Related Party Transactions —Fluence Energy LLC Agreement,” funding of redemptions of LLC Interests. The existence of authorized but

170

TABLE OF CONTENTS

unissued and unreserved common stock and preferred stock could make more difficult or discourage an attempt to obtain control of us by means of a proxy contest, tender offer, merger or otherwise.

Special Meetings of Stockholders

Our amended and restated bylaws will provide that from and after the date on which the aggregate number of outstanding shares of Class B-1 and Class B-2 common stock, voting together as a single class, cease to represent at least 50% of the total voting power of the outstanding shares of our capital stock, only the chairperson of our board of directors or a majority of our board of directors may call special meetings of our stockholders.

Limitation on Action by Written Consent

Our amended and restated certificate of incorporation will provide that from and after the date on which the aggregate number of outstanding shares of Class B-1 and Class B-2 common stock, voting together as a single class, cease to represent at least 50% of the total voting power of the outstanding shares of our capital stock, holders of our common stock will not be able to act by written consent without a meeting.

Advance Notice Requirements for Stockholder Proposals and Director Nominations

In addition, our amended and restated bylaws will establish an advance notice procedure for stockholder proposals to be brought before an annual meeting of stockholders, including proposed nominations of candidates for election to our board of directors. In order for any matter to be “properly brought” before a meeting, a stockholder will have to comply with advance notice and duration of ownership requirements and provide us with certain information. Stockholders at an annual meeting may only consider proposals or nominations specified in the notice of meeting or brought before the meeting by or at the direction of our board of directors or by a qualified stockholder of record on the record date for the meeting, who is entitled to vote at the meeting and who has delivered timely written notice in proper form to our secretary of the stockholder’s intention to bring such business before the meeting. These provisions could have the effect of delaying stockholder actions that are favored by the holders of a majority of our outstanding voting securities until the next stockholder meeting. Notwithstanding anything contained in our amended and restated bylaws to the contrary, such advance notice procedures shall not apply to a stockholder exercising its rights to designate persons for nomination for election to our board of directors in accordance with the provisions of the Stockholders Agreement for so long as it remains in effect.

Amendment of Certificate of Incorporation or Bylaws

The Delaware General Corporation Law provides generally that the affirmative vote of a majority of the shares entitled to vote on any matter is required to amend a corporation’s certificate of incorporation or bylaws, unless a corporation’s certificate of incorporation or bylaws, as the case may be, requires a greater percentage. Our amended and restated certificate of incorporation and amended and restated bylaws will provide that the affirmative vote of holders of at least 66 2/3% of the voting power of all of the then-outstanding shares of capital stock, voting as a single class, will be required to amend certain provisions of our amended and restated certificate of incorporation, including provisions relating to amending our amended and restated bylaws, the size of our board, removal of directors, director liability, vacancies on our board, special meetings, stockholder notices, actions by written consent and exclusive forum.

Section 203 of the DGCL

We will opt out of Section 203 of the DGCL. However, our amended and restated certificate of incorporation will contain provisions that are similar to Section 203. Specifically, our amended and restated certificate of incorporation will provide that, subject to certain exceptions, we will not be able to engage in a “business combination” with any “interested stockholder” for three years following the date that the person became an interested stockholder, unless the interested stockholder attained such status with the approval of our board of directors or unless the business combination is approved in a prescribed manner. A “business combination” includes, among other things, a merger or consolidation involving us and the “interested stockholder” and the sale of more than 10% of our assets. In general, an “interested stockholder” is any

171

TABLE OF CONTENTS

entity or person beneficially owning 15% or more of our outstanding voting stock and any entity or person affiliated with or controlling or controlled by such entity or person, provided that the Founders and certain of their related parties and their respective direct and indirect transferees shall not be considered “interested stockholders.”

Limitations on Liability and Indemnification of Officers and Directors

Our amended and restated certificate of incorporation and amended and restated bylaws provide indemnification for our directors and officers to the fullest extent permitted by the Delaware General Corporation Law. Prior to the consummation of the Transactions, we intend to enter into indemnification agreements with each of our directors and executive officers that may, in some cases, be broader than the specific indemnification provisions contained under Delaware law. In addition, as permitted by Delaware law, our amended and restated certificate of incorporation includes provisions that eliminate the personal liability of our directors for monetary damages resulting from breaches of certain fiduciary duties as a director. The effect of this provision is to restrict our rights and the rights of our stockholders in derivative suits to recover monetary damages against a director for breach of fiduciary duties as a director.

These provisions may be held not to be enforceable for violations of the federal securities laws of the United States.

Corporate Opportunity Doctrine

Delaware law permits corporations to adopt provisions renouncing any interest or expectancy in certain opportunities that are presented to the corporation or its officers, directors or stockholders. Our amended and restated certificate of incorporation will, to the maximum extent permitted from time to time by Delaware law, renounce any interest or expectancy that we have in, or right to be offered an opportunity to participate in, specified business opportunities that are from time to time presented to any director or stockholder who is not employed by us or our subsidiaries. Our amended and restated certificate of incorporation will provide that, to the fullest extent permitted by law, any director or stockholder who is not employed by us or our affiliates will not have any duty to refrain from (1) engaging in a corporate opportunity in the same or similar lines of business in which we or our affiliates now engage or propose to engage or (2) otherwise competing with us or our affiliates. In addition, to the fullest extent permitted by law, if any director or stockholder who is not employed by us or our subsidiaries acquires knowledge of a potential transaction or other business opportunity which may be a corporate opportunity for itself or himself or its or his affiliates or for us or our affiliates, such person will have no duty to communicate or offer such transaction or business opportunity to us or any of our affiliates and they may take any such opportunity for themselves or offer it to another person or entity, unless such opportunity was expressly offered to them solely in their capacity as a director, executive officer or employee of us or our affiliates. To the fullest extent permitted by Delaware law, no potential transaction or business opportunity may be deemed to be a corporate opportunity of the corporation or its subsidiaries unless (1) we or our subsidiaries would be permitted to undertake such transaction or opportunity in accordance with the amended and restated certificate of incorporation, (2) we or our subsidiaries, at such time have sufficient financial resources to undertake such transaction or opportunity, (3) we have an interest or expectancy in such transaction or opportunity, and (4) such transaction or opportunity would be in the same or similar line of our or our subsidiaries’ business in which we or our subsidiaries are engaged or a line of business that is reasonably related to, or a reasonable extension of, such line of business. Our amended and restated certificate of incorporation will not renounce our interest in any business opportunity that is expressly offered to an employee director or employee in his or her capacity as a director or employee of Fluence Energy, Inc.

Dissenters’ Rights of Appraisal and Payment

Under the DGCL, with certain exceptions, our stockholders will have appraisal rights in connection with a merger or consolidation of Fluence Energy, Inc. Pursuant to the DGCL, stockholders who properly request and perfect appraisal rights in connection with such merger or consolidation will have the right to receive payment of the fair value of their shares as determined by the Delaware Court of Chancery.

172

TABLE OF CONTENTS

Stockholders’ Derivative Actions

Under the DGCL, any of our stockholders may bring an action in our name to procure a judgment in our favor, also known as a derivative action, provided that the stockholder bringing the action is a holder of our shares at the time of the transaction to which the action relates or such stockholder’s stock thereafter devolved by operation of law.

Transfer Agent and Registrar

The transfer agent and registrar for our Class A common stock is Computershare Trust Company, N.A.

Trading Symbol and Market

We have applied to list our Class A common stock on the Nasdaq Global Market under the symbol “FLNC.”

SHARES ELIGIBLE FOR FUTURE SALE

Immediately prior to this offering, there was no public market for our Class A common stock. Future sales of substantial amounts of Class A common stock in the public market (including shares of Class A common stock issuable upon redemption or exchange of LLC Interests of certain of our Continuing Equity Owners), or the perception that such sales may occur, could adversely affect the market price of our Class A common stock. Although we have applied to have our Class A common stock listed on the Nasdaq, we cannot assure you that there will be an active public market for our Class A common stock.

Upon the closing of this offering, we will have outstanding an aggregate of 49,493,275 shares of Class A common stock, assuming the issuance of 31,000,000 shares of Class A common stock offered by us in this offering and the issuance of 18,493,275 shares of Class A common stock to the Blocker Shareholder in the Transactions, and assuming the underwriters do not exercise their option to purchase additional shares of our Class A common stock. Of these shares, all shares sold in this offering (including shares issued pursuant to the underwriters’ option to purchase additional shares) will be freely tradable without restriction or further registration under the Securities Act, except for any shares purchased by our “affiliates,” as that term is defined in Rule 144 under the Securities Act, whose sales would be subject to the Rule 144 resale restrictions described below, other than the holding period requirement.

The remaining 18,493,275 shares of Class A common stock will be “restricted securities,” as that term is defined in Rule 144 under the Securities Act. These restricted securities are eligible for public sale only if they are registered under the Securities Act or if they qualify for an exemption from registration under the Securities Act, including Rules 144 or 701 under the Securities Act, which are summarized below.

In addition, each common unit held by certain of our Founders will be redeemable, at the election of such Founder, for, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), newly-issued shares of our Class A common stock on a one-for-one basis or a cash payment equal to a volume weighted average market price of one share of Class A common stock for LLC Interest so redeemed, in each case, in accordance with the terms of the Fluence Energy LLC Agreement; provided that, at our election (determined solely by our independent directors (within the meaning of the rules of the Nasdaq) who are disinterested), we may effect a direct exchange by Fluence Energy, Inc. of such Class A common stock or such cash, as applicable, for such LLC Interests. In the event of cash settlement, Fluence Energy, Inc. would issue new shares of Class A common stock and use the proceeds from the sale of these newly-issued shares of Class A common stock to fully fund the cash settlement, which, in effect, limits the amount of the cash payment to the redeeming member. The Founders may, subject to certain exceptions, exercise such redemption right for as long as their LLC Interests remain outstanding. See “Certain Relationships and Related Party Transactions—Fluence Energy LLC Agreement.” Upon consummation of the Transactions, our Founders will hold 117,173,390 LLC Interests, all of which will be exchangeable for shares of our Class A common stock. The shares of Class A common stock we issue upon such exchanges would be “restricted securities” as defined in Rule 144 unless we register such issuances. However, we will enter into a Registration Rights Agreement with the Continuing Equity Owners that will require us, subject to customary conditions, to register under the Securities Act these shares of Class A common stock. See “Certain Relationships and Related Party Transactions—Registration Rights Agreement.”

Lock-Up Agreements

We and our directors, officers, and the holders of substantially all of our outstanding shares and share options have agreed subject to certain exceptions, that without the prior written consent of J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC on behalf of the underwriters, we and they will not, and will not publicly disclose an intention to, during the period beginning on the date of the lock-up agreement and ending at the close of business 180 days after the date of the final prospectus relating to the public offering (such period, the “restricted period”):

•

offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any Class A common stock or any securities convertible into or exercisable or exchangeable for Class A common stock;

174

TABLE OF CONTENTS

•

file any registration statement with the Securities and Exchange Commission relating to the offering of any Class A common stock or any securities convertible into or exercisable or exchangeable for Class A common stock; or

•

enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Class A common stock,

whether any such transaction described above is to be settled by delivery of Class A common stock or such other securities, in cash or otherwise. In addition, we and each such person agrees that, without the prior written consent of J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC on behalf of the underwriters, we or such other person will not, during the restricted period, make any demand for, or exercise any right with respect to, the registration of any Class A common stock or any security convertible into or exercisable or exchangeable for Class A common stock.

Upon the expiration of the lock-up period, substantially all of the shares subject to such lock-up restrictions will become eligible for sale, subject to the limitations discussed above.

Rule 144

In general, under Rule 144 under the Securities Act as currently in effect, a person (or persons whose shares are aggregated) who is not deemed to have been an affiliate of ours at any time during the three months preceding a sale, and who has beneficially owned restricted securities within the meaning of Rule 144 for at least six months (including any period of consecutive ownership of preceding non-affiliated holders) would be entitled to sell those shares, subject only to the availability of current public information about us. A non-affiliated person who has beneficially owned restricted securities within the meaning of Rule 144 for at least one year would be entitled to sell those shares without regard to the provisions of Rule 144.

A person (or persons whose shares are aggregated) who is deemed to be an affiliate of ours and who has beneficially owned restricted securities within the meaning of Rule 144 for at least six months would be entitled to sell within any three-month period a number of shares that does not exceed the greater of 1% of the then-outstanding shares of our Class A common stock or the average weekly trading volume of our Class A common stock reported through Nasdaq during the four calendar weeks preceding the filing of notice of the sale. Such sales are also subject to certain manner of sale provisions, notice requirements, and the availability of current public information about us.

Rule 701

In general, under Rule 701, any of our employees, directors, officers, consultants or advisors who purchases shares from us in connection with a compensatory stock or option plan or other written agreement before the effective date of the registration statement of which this prospectus forms a part is entitled to sell such shares 90 days after such effective date in reliance on Rule 144. Our affiliates can resell shares in reliance on Rule 144 without having to comply with the holding period requirement, and non-affiliates of the issuer can resell shares in reliance on Rule 144 without having to comply with the current public information and holding period requirements.

The SEC has indicated that Rule 701 will apply to typical stock options granted by an issuer before it becomes subject to the reporting requirements of the Exchange Act, along with the shares acquired upon exercise of such options, including exercises after an issuer becomes subject to the reporting requirements of the Exchange Act.

Equity Plans

We intend to file one or more registration statements on Form S-8 under the Securities Act to register the offer and sale of all shares of Class A common stock subject to outstanding stock options and phantom units (including options issued pursuant to the Existing Equity Plan which will convert upon effectiveness of this offering into options to acquire shares of Class A common stock) and Class A common stock issued or issuable under our 2021 Plan (or which may be issued in respect of awards under the Existing Phantom Equity Plan). As of the date of this prospectus, options and phantom units representing 979,300 LLC Interests

175

TABLE OF CONTENTS

were outstanding, which will convert into options and phantom units representing an aggregate of 14,488,372 shares of Class A common stock. A total of approximately 9,500,000 shares of our Class A common stock will be available for issuance to certain of our directors, executive officers and consultants under our 2021 Plan following with this offering. The number of shares of our Class A common stock that may be issued in respect of awards under the Existing Phantom Equity Plan will depend on the value of our Class A common stock following this offering.

We expect to file the registration statement covering shares offered pursuant to the Existing Equity Plan and our 2021 Plan (and, if necessary, in respect of awards under the Existing Phantom Equity Plan) shortly after the date of this prospectus, permitting the resale of such shares by nonaffiliates in the public market without restriction under the Securities Act and the sale by affiliates in the public market subject to compliance with the resale provisions of Rule 144.

MATERIAL U.S. FEDERAL INCOME TAX CONSEQUENCES
TO NON-U.S. HOLDERS OF CLASS A COMMON STOCK

The following discussion is a summary of the material U.S. federal income tax consequences to Non-U.S. Holders (as defined below) of the purchase, ownership, and disposition of our Class A common stock issued pursuant to this offering, but does not purport to be a complete analysis of all potential tax effects. The effects of other U.S. federal tax laws, such as estate and gift tax laws, and any applicable state, local or non-U.S. tax laws are not discussed. This discussion is based on the U.S. Internal Revenue Code of 1986, as amended (the “Code”), Treasury Regulations promulgated thereunder, judicial decisions, and published rulings and administrative pronouncements of the U.S. Internal Revenue Service (the “IRS”), in each case in effect as of the date hereof. These authorities may change or be subject to differing interpretations. Any such change or differing interpretation may be applied retroactively in a manner that could adversely affect a Non-U.S. Holder of our Class A common stock. We have not sought and will not seek any rulings from the IRS regarding the matters discussed below. There can be no assurance the IRS or a court will not take a contrary position to that discussed below regarding the tax consequences of the purchase, ownership, and disposition of our Class A common stock.

This discussion is limited to Non-U.S. Holders that hold our Class A common stock as a “capital asset” within the meaning of Section 1221 of the Code (generally, property held for investment). This discussion does not address all U.S. federal income tax consequences relevant to a Non-U.S. Holder’s particular circumstances, including the alternative minimum tax and the impact of the Medicare contribution tax on net investment income. In addition, it does not address consequences relevant to Non-U.S. Holders subject to special rules, including, without limitation:

•

U.S. expatriates and former citizens or long-term residents of the United States;

•

persons holding our Class A common stock as part of a hedge, straddle or other risk reduction strategy or as part of a conversion transaction or other integrated investment;

•

banks, insurance companies, and other financial institutions;

•

brokers, dealers or traders in securities;

•

“controlled foreign corporations,” “passive foreign investment companies,” and corporations that accumulate earnings to avoid U.S. federal income tax;

•

partnerships or other entities or arrangements treated as partnerships for U.S. federal income tax purposes (and investors therein);

•

tax-exempt organizations or governmental organizations;

•

persons deemed to sell our Class A common stock under the constructive sale provisions of the Code;

•

persons who hold or receive our Class A common stock pursuant to the exercise of any employee stock option or otherwise as compensation;

•

tax-qualified retirement plans;

•

“qualified foreign pension funds” as defined in Section 897(l)(2) of the Code and entities all of the interests of which are held by qualified foreign pension funds; and

•

persons subject to special tax accounting rules as a result of any item of gross income with respect to the stock being taken into account in an applicable financial statement.

If an entity or arrangement treated as a partnership for U.S. federal income tax purposes holds our Class A common stock, the tax treatment of an owner in such an entity will depend on the status of the owner, the activities of such entity, and certain determinations made at the owner level. Accordingly, entities or arrangements treated as partnerships for U.S. federal income tax purposes holding our Class A common stock and the owners in such entities should consult their tax advisors regarding the U.S. federal income tax consequences to them.

177

TABLE OF CONTENTS

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY AND IS NOT TAX ADVICE. INVESTORS SHOULD CONSULT THEIR TAX ADVISORS WITH RESPECT TO THE APPLICATION OF THE U.S. FEDERAL INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY TAX CONSEQUENCES OF THE PURCHASE, OWNERSHIP, AND DISPOSITION OF OUR CLASS A COMMON STOCK ARISING UNDER THE U.S. FEDERAL ESTATE OR GIFT TAX LAWS OR UNDER THE LAWS OF ANY STATE, LOCAL OR NON-U.S. TAXING JURISDICTION OR UNDER ANY APPLICABLE INCOME TAX TREATY.

Definition of a Non-U.S. Holder

For purposes of this discussion, a “Non-U.S. Holder” is any beneficial owner of our Class A common stock that is neither a “U.S. person” nor an entity or arrangement treated as a partnership for U.S. federal income tax purposes. A U.S. person is any person that, for U.S. federal income tax purposes, is or is treated as any of the following:

•

an individual who is a citizen or resident of the United States;

•

a corporation created or organized under the laws of the United States, any state thereof or the District of Columbia;

•

an estate, the income of which is subject to U.S. federal income tax regardless of its source; or

•

a trust that (1) is subject to the primary supervision of a U.S. court and the control of one or more “United States persons” (within the meaning of Section 7701(a)(30) of the Code) or (2) has a valid election in effect to be treated as a United States person for U.S. federal income tax purposes.

Distributions

If we make distributions of cash or property on our Class A common stock, such distributions will constitute dividends for U.S. federal income tax purposes to the extent paid from our current or accumulated earnings and profits, as determined under U.S. federal income tax principles. Amounts not treated as dividends for U.S. federal income tax purposes will constitute a return of capital and first be applied against and reduce a Non-U.S. Holder’s adjusted tax basis in its Class A common stock, but not below zero. Any excess will be treated as capital gain and will be treated as described below under “—Sale or Other Taxable Disposition.”

Subject to the discussion below on effectively connected income, dividends paid to a Non-U.S. Holder of our Class A common stock will be subject to U.S. federal withholding tax at a rate of 30% of the gross amount of the dividends (or such lower rate specified by an applicable income tax treaty, provided the Non-U.S. Holder furnishes a valid IRS Form W-8BEN or W-8BEN-E (or other applicable documentation) certifying qualification for the lower treaty rate). A Non-U.S. Holder that does not timely furnish the required documentation, but that qualifies for a reduced treaty rate, may obtain a refund of any excess amounts withheld by timely filing an appropriate claim for refund with the IRS. Non-U.S. Holders should consult their tax advisors regarding their entitlement to benefits under any applicable income tax treaty.

If dividends paid to a Non-U.S. Holder are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such dividends are attributable), the Non-U.S. Holder will be exempt from the U.S. federal withholding tax described above. To claim the exemption, the Non-U.S. Holder must furnish to the applicable withholding agent a valid IRS Form W-8ECI, certifying that the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States.

Any such effectively connected dividends will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected dividends, as adjusted for certain items. Non-U.S. Holders should consult their tax advisors regarding any applicable tax treaties that may provide for different rules.

178

TABLE OF CONTENTS

Sale or Other Taxable Disposition

Subject to the discussion below under “—Information Reporting and Backup Withholding” and “—Additional Withholding Tax on Payments Made to Foreign Accounts,” a Non-U.S. Holder will not be subject to U.S. federal income tax on any gain realized upon the sale or other taxable disposition of our Class A common stock unless:

•

the gain is effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, the Non-U.S. Holder maintains a permanent establishment in the United States to which such gain is attributable);

•

the Non-U.S. Holder is a nonresident alien individual present in the United States for 183 days or more during the taxable year of the disposition and certain other requirements are met; or

•

our Class A common stock constitutes a U.S. real property interest (“USRPI”) by reason of our status as a U.S. real property holding corporation (“USRPHC”) for U.S. federal income tax purposes.

Gain described in the first bullet point above generally will be subject to U.S. federal income tax on a net income basis at the regular graduated rates. A Non-U.S. Holder that is a corporation also may be subject to a branch profits tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on such effectively connected gain, as adjusted for certain items.

A holder described in the second bullet point above will be subject to U.S. federal income tax at a rate of 30% (or such lower rate specified by an applicable income tax treaty) on any gain realized upon the sale or other taxable disposition of our Class A common stock, which may be offset by certain U.S. source capital losses of the Non-U.S. Holder (even though the individual is not considered a resident of the United States), provided the Non-U.S. Holder has timely filed U.S. federal income tax returns with respect to such losses.

With respect to the third bullet point above, we believe we currently are not, and do not anticipate becoming, a USRPHC. Because the determination of whether we are a USRPHC depends, however, on the fair market value of our USRPIs relative to the fair market value of our non-U.S. real property interests and our other business assets, there can be no assurance we currently are not a USRPHC or will not become one in the future. Even if we are or were to become a USRPHC, gain arising from the sale or other taxable disposition by a Non-U.S. Holder of our Class A common stock will not be subject to U.S. federal income tax if our Class A common stock is “regularly traded,” as defined by applicable Treasury Regulations, on an established securities market, and such Non-U.S. Holder owned, actually and constructively, 5% or less of our Class A common stock throughout the shorter of the five-year period ending on the date of the sale or other taxable disposition or the Non-U.S. Holder’s holding period.

Non-U.S. Holders should consult their tax advisors regarding potentially applicable income tax treaties that may provide for different rules.

Information Reporting and Backup Withholding

Payments of dividends on our Class A common stock will not be subject to backup withholding, provided the applicable withholding agent does not have actual knowledge or reason to know the holder is a United States person and the holder either certifies its non-U.S. status, such as by furnishing a valid IRS Form W-8BEN, W-8BEN-E or W-8ECI, or otherwise establishes an exemption. However, information returns are required to be filed with the IRS in connection with any distributions on our Class A common stock paid to the Non-U.S. Holder, regardless of whether such distributions constitute dividends or whether any tax was actually withheld. In addition, proceeds of the sale or other taxable disposition of our Class A common stock within the United States or conducted through certain U.S.-related brokers generally will not be subject to backup withholding or information reporting, if the applicable withholding agent receives the certification described above and does not have actual knowledge or reason to know that such holder is a United States person, or the holder otherwise establishes an exemption. Proceeds of a disposition of our Class A common stock conducted through a non-U.S. office of a non-U.S. broker generally will not be subject to backup withholding or information reporting.

179

TABLE OF CONTENTS

Copies of information returns that are filed with the IRS may also be made available under the provisions of an applicable treaty or agreement to the tax authorities of the country in which the Non-U.S. Holder resides or is established.

Backup withholding is not an additional tax. Any amounts withheld under the backup withholding rules may be allowed as a refund or a credit against a Non-U.S. Holder’s U.S. federal income tax liability, provided the required information is timely furnished to the IRS.

Additional Withholding Tax on Payments Made to Foreign Accounts

Withholding taxes may be imposed under Sections 1471 to 1474 of the Code (such Sections commonly referred to as the Foreign Account Tax Compliance Act, or “FATCA”) on certain types of payments made to non-U.S. financial institutions and certain other non-U.S. entities. Specifically, a 30% withholding tax may be imposed on dividends on, or (subject to the proposed Treasury Regulations discussed below) gross proceeds from the sale or other disposition of, our Class A common stock paid to a “foreign financial institution” or a “non-financial foreign entity” (each as defined in the Code), unless (1) the foreign financial institution undertakes certain diligence and reporting obligations, (2) the non-financial foreign entity either certifies it does not have any “substantial United States owners” (as defined in the Code) or furnishes identifying information regarding each substantial United States owner, or (3) the foreign financial institution or non-financial foreign entity otherwise qualifies for an exemption from these rules. If the payee is a foreign financial institution and is subject to the diligence and reporting requirements in (1) above, it must enter into an agreement with the U.S. Department of the Treasury requiring, among other things, that it undertake to identify accounts held by certain “specified United States persons” or “United States owned foreign entities” (each as defined in the Code), annually report certain information about such accounts, and withhold 30% on certain payments to non-compliant foreign financial institutions and certain other account holders. Foreign financial institutions located in jurisdictions that have an intergovernmental agreement with the United States governing FATCA may be subject to different rules.

Under the applicable Treasury Regulations and administrative guidance, withholding under FATCA generally applies to payments of dividends on our Class A common stock. While withholding under FATCA would also have applied to payments of gross proceeds from the sale or other disposition of stock, proposed Treasury Regulations eliminate FATCA withholding on payments of gross proceeds entirely. Taxpayers generally may rely on these proposed Treasury Regulations until final Treasury Regulations are issued.

Prospective investors should consult their tax advisors regarding the potential application of withholding under FATCA to their investment in our Class A common stock.

The underwriters and the representatives are collectively referred to as the “underwriters” and the “representatives,” respectively. The underwriters are offering the Class A common stock subject to their acceptance of the Class A common stock from us and subject to prior sale. The underwriting agreement provides that the obligations of the several underwriters to pay for and accept delivery of the Class A common stock offered by this prospectus are subject to the approval of certain legal matters by their counsel and to certain other conditions. The underwriters are obligated to take and pay for all of the Class A common stock offered by this prospectus if any such shares are taken. However, the underwriters are not required to take or pay for the shares covered by the underwriters’ over-allotment option described below.

The underwriters initially propose to offer part of the Class A common stock directly to the public at the offering price listed on the cover page of this prospectus and part to certain dealers. After the initial offering of the Class A common stock, the offering price and other selling terms may from time to time be varied by the representatives.

The Company has granted to the underwriters an option, exercisable for 30 days from the date of this prospectus, to purchase up to 4,650,000 Class A common stock at the public offering price listed on the cover page of this prospectus, less underwriting discounts and commissions. The underwriters may exercise this option solely for the purpose of covering over-allotments, if any, made in connection with the offering of the Class A common stock offered by this prospectus. To the extent the option is exercised, each underwriter will become obligated, subject to certain conditions, to purchase about the same percentage of the additional Class A common stock as the number listed next to the underwriter’s name in the preceding table bears to the total number of Class A common stock listed next to the names of all underwriters in the preceding table.

The following table shows the per share and total public offering price, underwriting discounts and commissions, and proceeds before expenses to us. These amounts are shown assuming both no exercise and full exercise of the underwriters’ option to purchase up to an additional 4,650,000 shares of Class A common stock.

provided that:

J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC, in their sole discretion, may release the Class A common stock and other securities subject to the lock-up agreements described above in whole or in part at any time.

In order to facilitate the offering of the Class A common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect the price of the Class A common stock. Specifically, the underwriters may sell more shares than they are obligated to purchase under the underwriting agreement, creating a short position. A short sale is covered if the short position is no greater than the number of shares available for purchase by the underwriters under the over-allotment option. The underwriters can close out a covered short sale by exercising the over-allotment option or purchasing shares in the open market. In determining the source of shares to close out a covered short sale, the underwriters will consider, among other things, the open market price of shares compared to the price available under the over-allotment option. The underwriters may also sell shares in excess of the over-allotment option, creating a naked short position. The underwriters must close out any naked short position by purchasing shares in the open market. A naked short position is more likely to be created if the underwriters are concerned that there may be downward pressure on the price of the Class A common stock in the open market after pricing that could adversely affect investors who purchase in this offering. As an additional means of facilitating this offering, the underwriters may bid for, and purchase, Class A common stock in the open market to stabilize the price of the Class A common stock. These activities may raise or maintain the market price of the Class A common stock above independent market levels or prevent or retard a decline in the market price of the Class A common stock. The underwriters are not required to engage in these activities and may end any of these activities at any time.

The underwriters may offer and sell the Class A common stock through certain of their affiliates or other registered broker-dealers or selling agents.

We and the underwriters have agreed to indemnify each other against certain liabilities, including liabilities under the Securities Act.

A prospectus in electronic format may be made available on websites maintained by one or more underwriters participating in this offering. The representatives may agree to allocate a number of Class A

184

common stock to underwriters for sale to their online brokerage account holders. Internet distributions will be allocated by the representatives to underwriters that may make Internet distributions on the same basis as other allocations.

Such investment and securities activities may involve our securities and instruments. The underwriters and their respective affiliates may also make investment recommendations or publish or express independent research views in respect of such securities or instruments and may at any time hold, or recommend to clients that they acquire, long or short positions in such securities and instruments.

Pricing of the Offering

Prior to this offering, there has been no public market for our Class A common stock. The initial public offering price was determined by negotiations between us and the representatives. Among the factors considered in determining the initial public offering price were our future prospects and those of our industry in general, our sales, earnings and certain other financial and operating information in recent periods, and the price-earnings ratios, price-sales ratios, market prices of securities, and certain financial and operating information of companies engaged in activities similar to ours.

Directed Share Program

At our request, the underwriters have reserved up to 5.0% of the shares of Class A common stock to be offered by this prospectus for sale, at the initial public offering price, to directors, officers, employees, business associates and related persons of Fluence Energy, Inc. If purchased by these persons, these shares will not be subject to a lock-up restriction, except in the case of shares purchased by any of our directors or executive officers, which shares will be subject to a 180-day lock-up restriction (as described above). The number of shares of Class A common stock available for sale to the general public will be reduced to the extent these individuals purchase such reserved shares. Any reserved shares that are not so purchased will be offered by the underwriters to the general public on the same basis as the other shares of Class A common stock offered by this prospectus.

Report of Independent Registered Public Accounting Firm

To the Members and the Board of Directors of Fluence Energy, LLC

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Fluence Energy, LLC (the Company) as of September 30, 2020 and 2019, the related consolidated statements of operations and comprehensive loss, members’ deficit and cash flows for each of the two years in the period ended September, 2020, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at September 30, 2020 and 2019, and the results of its operations and its cash flows for each of the two years in the period ended September 30, 2020, in conformity with U.S. generally accepted accounting principles.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ Ernst & Young LLP

We have served as the Company’s auditor since 2018.

FLUENCE ENERGY, LLC

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
September 30, 2020 and 2019

Organization and Operations

Fluence Energy, LLC (‘‘Fluence’’), a Delaware limited liability company, was formed on June 30, 2017, and commenced operations on January 1, 2018 (the ‘‘Effective Date’’). Fluence, with its wholly owned subsidiaries including Fluence Energy GmbH in Germany, Fluence Energy Pty Ltd. in Australia, and Fluence Energy Inc. in the Philippines. is primarily engaged in the construction and sale of battery-based energy storage products and provides related operational services. As of September 30, 2020, AES Grid Stability LLC (‘‘AES’’) and Siemens Industry, Inc. (‘‘Siemens’’) (together, ‘‘Members’’) each holds 3,960,000 units, or 50% of the limited liability interest, of the Company. Except where the content clearly indicates otherwise, “Fluence,” “we,” “us,” “our” or the “Company” refers to Fluence Energy, LLC and its wholly owned subsidiaries.

The Company’s chief operating decision maker (‘‘CODM’’) is its Chief Executive Officer. The Company’s CODM reviews financial information on a consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one operating segment, which corresponds to one reportable segment.

The Company’s fiscal year begins on October 1 and ends on September 30. Consequently, fiscal year 2019 (‘‘FY 2019’’) ended on September 30, 2019 and fiscal year 2020 (‘‘FY 2020’’) ended on September 30, 2020.

Summary of Significant Accounting Policies and Estimates

Principles of Accounting and Consolidation

The accompanying consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (‘‘U.S. GAAP’’) and under the rules of the Securities and Exchange Commission (the ‘‘SEC’’). The accompanying consolidated financial statements include the accounts of Fluence and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Emerging Growth Company Status

The Company is an emerging growth company, as defined in the Jumpstart Our Business Startups Act of 2012 (the ‘‘JOBS Act’’), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved. The JOBS Act also provides that emerging growth companies can elect to adopt new or revised accounting standards issued subsequent to the enactment of the JOBS Act under private company effective dates.

The Company has elected to use this extended transition period to adopt new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date that it is (i) no longer an emerging growth company or (ii) affirmatively and irrevocably opts out of the extended transition period provided in the JOBS Act. As a result, the consolidated financial statements may not be comparable to companies that comply with the new or revised accounting pronouncements as of public company effective dates.

Use of Estimates

The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the accompanying

F-7

TABLE OF CONTENTS

consolidated financial statements and accompanying notes. Actual results could differ materially from those estimates. Items subject to such estimates and assumptions include: the carrying amount and estimated useful lives of long-lived assets; impairment of goodwill and long-lived assets; valuation allowances for inventories; deferred tax assets; revenue recognized under the percentage-of-completion method; accrued bonuses; and various project related provisions including but not limited to estimated losses, warranty obligations, and liquidated damages.

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents include cash on-hand and highly liquid investments readily convertible to cash, with an original maturity of 90 days or less when purchased.

Cash restricted for use as a result of financing or other obligations is classified separately as restricted cash in other current assets.

The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the Company’s consolidated balance sheets and sums to the total of such amounts shown on the consolidated statements of cash flows (in thousands):

	As of September 30,
	2020			2019
Cash and cash equivalents		$	93,815		$	84,113
Restricted cash included in other current assets			1,236			2,907
Total cash, cash equivalents and restricted cash shown in the statements of cash flows		$	95,051		$	87,020

Restricted cash included in other current assets on the consolidated balance sheets as of September 30, 2020 consists of $915 thousand collateral for credit card program (2019: $904 thousand) and $321 thousand of collateral for outstanding bank guarantee (2019: $2,003 thousand).

Trade Receivables

Trade receivables represent actual billings that are generally due within 30 days from the invoice date, and do not bear interest. Receivables are carried at amortized cost. The Company periodically assesses collectability of accounts receivable and records an allowance for doubtful accounts for the estimated uncollectable amount when deemed appropriate. As of September 30, 2020 and 2019, no allowance for doubtful accounts was recognized.

Advances to Suppliers

Advances are given to suppliers based on the contract terms of respective agreements and are presented on a separate line on the consolidated balance sheets. These advances are recovered through the receipt of goods and services mainly used in the production of battery-based energy storage products.

Foreign Currency Transactions

An entity’s functional currency is the currency of the primary economic environment in which the entity operates and is generally the currency in which the entity generates and expends cash. The reporting currency of the Company is the U.S. dollar. Monetary and non-monetary assets and liabilities denominated in foreign currencies are remeasured into U.S. dollars using the year-end exchange rates, while revenues and expenses denominated in foreign currencies are remeasured at weighted average exchange rates prevailing during the year. Resultant foreign currency exchange adjustments for monetary assets and liabilities are recorded in earnings on the accompanying consolidated statements of operations and comprehensive loss. Adjustments arising from the translation of the balance sheets of subsidiaries that have a functional currency other than the U.S. dollar are recorded as a component of members’ (deficit) equity in accumulated other comprehensive income (loss).

TABLE OF CONTENTS

Revenue and Cost Recognition

The Company commenced operations on January 1, 2018 and immediately adopted Accounting Standards Updated (‘‘ASU’’) 2014-09, Revenue from Contracts with Customers and all related amendments (collectively known as Accounting Standards Codification 606, or ‘‘ASC 606’’). The Company’s revenue recognition policy included herein is based on the application of ASC 606. As of September 30, 2020, the Company’s revenue was generated primarily from sale of battery-based energy storage products and providing operational service related to storage products.

Revenue from Sale of Battery-Based Energy Storage Products: Fluence enters into contracts with utility companies, developers, and commercial and industrial customers to design and build battery-based energy storage products. Each storage product is customized depending on the customer’s energy needs. Customer payments are due upon meeting certain milestones that are consistent with contract-specific phases of a project. The Company determines the transaction price based on the consideration expected to be received which includes estimates of liquidated damages or other variable consideration that are included in the transaction price in accordance with ASC 606. The transaction price identified is allocated to each distinct performance obligation to deliver a good or service based on the relative standalone selling prices. Generally, the Company’s contracts to design and build battery-based storage products are determined to have one performance obligation. The Company believes that the prices negotiated with each individual customer are representative of the stand-alone selling price of the product.

The Company recognizes revenue over time as a result of the continuous transfer of control of our product to the customer. This continuous transfer of control to the customer is supported by clauses in the contracts that provide enforceable rights to payment of the transaction price associated with work performed to date for products that do not have an alternative use to the Company and/or the project is built on customer’s land that is under the customer’s control.

Revenue for these performance obligations is recognized using the percentage of completion method based on cost incurred as a percentage of total estimated contract costs. Contract costs include all direct material and labor costs related to contract performance. Pre-contract costs with no future benefit are expensed in the period in which they are incurred. Since the revenue recognition of these contracts depends on estimates, which are assessed continually during the term of the contract, recognized revenues and profit are subject to revisions as the contract progresses to completion. The cumulative effects of revisions of estimated total contract costs and revenues, together with any contract reserves which may be deemed appropriate, are recorded in the period in which the facts and changes in circumstance become known. Due to the uncertainties inherent in the estimation process, it is reasonably possible that these estimates will be revised in a different period. When a loss is forecasted for a contract, the full amount of the anticipated loss is recognized in the period in which it is determined that a loss will occur. Refer to Loss Contracts below for further discussion.

Revenue from Services: Fluence also enters into long-term service agreements with customers to provide operational services related to battery-based energy storage products. The services include maintenance, monitoring, and other minor services. The Company accounts for the services as a single performance obligation as the services are substantially the same and have the same pattern of transfer to the customers. Straight-line revenue recognition method is applied for these types of services. The Company believes using a time-based method to measure progress is appropriate as the performance obligations are satisfied evenly over time based on the fact that customers receive the services evenly and cost pattern does not change significantly over the service period. Revenue is recognized by dividing the total contract revenue over the service period.

Some of the agreements also provide capacity guarantees which stand for a commitment to perform certain augmentation activities to maintain the level of battery capacity specified in the agreement. Augmentation activities would typically be represented by installation of additional batteries, and other components as needed, to compensate for partially lost capacity due to degradation of batteries over time. These services are treated as service-type warranties and are accounted for as separate performance obligations from other services discussed above. Performance obligations of the services are satisfied over time. The percentage of completion revenue recognition method is applied for service type warranties as the cost pattern is expected to change significantly with little to no operating costs incurred in the earlier years and larger

F-9

TABLE OF CONTENTS

costs incurred in later years when augmentation is required to restore the required capacity, for example, adding more batteries or changing some existing modules with declined capacity.

For both products and service contracts where there are multiple performance obligations in a single contract, the Company allocates the consideration to the various obligations in the contract based on the relative standalone selling price method. Standalone selling prices are estimated based on estimated costs plus margin or using market data for comparable products when estimated costs are not imputable.

Revenue is recorded net of any taxes assessed on and collected from customers, which are remitted to the governmental authorities.

Cost of Goods and Services: Cost of goods and services are recognized when services are performed, or control of goods are transferred to the customers, which is generally based upon International Commercial Terms (commonly referred to as ‘‘incoterms’’) stated in corresponding supply agreements or purchase orders.

Unbilled Receivables: Unbilled receivables represent the excess of revenues recognized over billings to date on certain contracts.

Deferred Revenue: Deferred revenue represents the excess billings to date over the amount of revenue recognized to date. Contract advances represent amounts received by the Company upon signing of the related contracts with customers. The advances are offset proportionately against progress billings. Any outstanding portion is included in deferred revenue on the accompanying consolidated balance sheets.

Loss Contracts: A contact becomes a loss contract when its estimated total costs are expected to exceed its total revenue. The Company accrues the full loss expected in the period a loss contract is identified which is recorded in current liabilities—accruals and provisions and cost of goods and services on the Company’s consolidated balance sheets and consolidated statements of operations and comprehensive loss, respectively.

Warranty Costs: The Company provides a limited warranty related to the successful operation of battery-based energy storage solutions, apart from the service type warranties described above and are normally provided for a limited period of time from one to three years after the commercial operation date. The warranties are considered assurance-type warranties which provide a guarantee of quality of the products. The Company accrues for expected warranty costs based on historical activity and expectations of future costs at the time of commercial operation date. Periodically, the Company evaluates and adjusts warranty costs to the extent that actual warranty costs materially differ from the original estimates. Extended warranties that customers purchase separately from the related products and services are accounted for as separate performance obligations. Both warranty fees and associated costs are accounted for after the commercial operation date of the related battery product. Warranty costs accrued are included in current liabilities—accruals and provisions and cost of goods and services on the consolidated balance sheets consolidated statements of operations and comprehensive loss, respectively.

Inventory, Net

Inventory consists of batteries and equipment, cases, inverters, and spare parts which are used in ongoing battery storage projects for sale. Inventory is stated at the lower of cost or net realizable value with cost being determined by the specific identification method. The Company periodically reviews its inventory for potential obsolescence and write down of its inventory, as appropriate, to net realizable value based on its assessment of market conditions.

Impairment of Long-Lived Assets

The Company evaluates the recoverability of its property and equipment, and intangible assets whenever events or changes in circumstances indicate that their carrying amount may not be recoverable. The assets are considered impaired when their fair value is less than their carrying value. Impairment charges are calculated as the difference between the discounted expected future cash flows, or other accepted valuation techniques to determine fair value and the assets’ carrying amount at the date of the triggering event.

F-10

TABLE OF CONTENTS

Intangible Assets

Intangible assets are stated at their historical cost and amortized on a straight-line basis over their expected useful lives.

Operating Expenses

Operating expenses include research and development, sales and marketing, general and administrative expenses, and depreciation and amortization.

Research and development expenses represent personnel costs of the technology team, and costs of materials and services procured for research and development projects.

Sales and marketing expenses represent personnel costs of the sales team and all marketing expenses.

General and administrative expenses represent personnel costs, rent, IT expenses insurance, and external providers for payroll, accounting, consulting and others.

Depreciation and amortization are expenses associated with property and equipment and contributed intangible assets, consisting of intellectual property rights.

Income Taxes

The Company is treated as a partnership for U.S. federal income tax purposes. As such, the members are individually liable for their own distributable share of taxable income or loss. No provision has been made in the accompanying consolidated financial statements for U.S. federal, state or local income taxes.

Foreign subsidiaries of the Company account for income taxes and the related accounts in accordance with ASC 740, Income Taxes. Under ASC 740, deferred tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse.

The Company recognizes the tax benefits from uncertain tax positions if it is more likely than not that the position will be sustained on examination by the taxing authorities. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. As of September 30, 2020 and 2019, the Company has not recognized tax benefits relating to uncertain tax positions.

The preparation of income tax returns requires the use of management’s estimates and interpretations which may be subjected to review by the respective taxing authorities and may result in an assessment of additional taxes, penalties and interest. The period from January 1, 2018 until September 30, 2020 remains subject to examination by foreign, federal and state taxing authorities.

Fair Value Measurements

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs and to minimize the use of unobservable inputs. The following fair value hierarchy, defined by ASC 820, Fair Value Measurements, is used to classify assets and liabilities based on the observable inputs and unobservable inputs used to value the assets and liabilities:

Level 1—Quoted prices are available in active markets for identical assets or liabilities as of the reporting date. Active markets are those in which transactions for the asset or liability occur in sufficient frequency and volume to provide pricing information on an ongoing basis.

F-11

TABLE OF CONTENTS

Level 2—Pricing inputs are other than quoted prices in active markets included in Level 1, which are either directly or indirectly observable as of the reporting date. Level 2 inputs include those financial instruments that are valued using models or other valuation methodologies. These models are primarily industry-standard models that consider various assumptions, including quoted prices, time value, volatility factors, and current market and contractual prices for the underlying instruments, as well as other relevant economic measures. Substantially all of these assumptions are observable in the marketplace throughout the full term of the instrument, can be derived from observable data or are supported by observable levels at which transactions are executed in the marketplace.

Level 3—Pricing inputs include significant inputs that are generally less observable from objective sources. These inputs may be used with internally developed methodologies that result in management’s best estimate of fair value from the perspective of a market participant. The Company does not have any recurring Level 3 fair value measurements.

The Company’s cash equivalents include term deposits with original maturity of less than three months and are recorded at amortized cost. Fair value of cash equivalents approximates the carrying amount using Level 2 inputs. The carrying amounts of trade receivables, accounts payable and short-term debt obligations approximate fair values due to their short maturities using Level 2 inputs.

Earnings per Unit (EPU)

The Company calculates basic earnings per common LLC member unit by dividing net loss, by the average number of common LLC member unit outstanding during the period. Diluted earnings per unit is calculated in a similar manner after consideration of the potential dilutive effect of common LLC member unit equivalents on the average number of common LLC member units outstanding during the period. Dilution is not considered when a net loss is reported. Common LLC member unit equivalents that have an antidilutive effect are excluded from the computation of diluted earnings per common LLC member unit. As of September 30, 2020 and 2019, the Company had no outstanding common LLC member unit equivalents.

Unit Split

In December 2020, the Company approved an amendment to their Limited Liability Company Agreement to effect a 1:1,320 unit split of the Company’s common LLC member units, which was effected on December 29, 2020. The par value of the common unit was not adjusted as a result of the unit split. All common LLC member units and per unit data have been retrospectively revised to reflect the unit split.

Recent Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (the ‘‘FASB’’) issued ASU 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in ASC 840, Leases. This standard requires all leases to be recognized on the consolidated balance sheet. ASU 2016-02 was effective for public companies for fiscal year beginning after December 15, 2018. As an emerging growth company, Fluence is permitted to defer adoption until the non-public company adoption date, i.e. annual periods starting after December 15, 2021. Early application is permitted for all entities. The FASB has issued several amendments to ASU 2016-02, including ASU 2018-11, Leases (Topic 842): Targeted Improvements that introduced an additional transition method permitting an entity to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. ASU 2016-02 includes optional practical expedients intended to reduce the cost and complexity to implement the new lease standard, such as an option to maintain the current lease classification for all existing lease arrangements and the option to use hindsight in evaluating lessee options to extend or terminate a lease. The Company’s existing lease population is mainly comprised of operating leases for office space. It plans to utilize the available practical expedients to record the impact of adoption prospectively, maintain the current lease classification for all existing leasing arrangements, and use hindsight in determining the lease term. The Company is currently evaluating the impact of adoption on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This guidance removes certain exceptions related to the approach for

F-12

TABLE OF CONTENTS

intraperiod tax allocations, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. The guidance also clarifies and simplifies other areas of ASC 740. ASU 2019-12 is effective for the Company on October 1, 2022. Certain amendments must be applied on a prospective basis, certain amendments must be applied on a retrospective basis, and certain amendments must be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings/(deficit) in the period of adoption. The Company is evaluating the impact of this guidance as well as timing of adoption.

In February 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326). This standard updates the impairment model for financial assets measured at amortized cost, known as the Current Expected Credit Loss (“CECL”) model. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking expected loss model that generally will result in the earlier recognition of allowance for losses. ASU 2016-13 was effective for public companies for annual periods starting after December 15, 2019. As an EGC, Fluence is permitted to defer adoption until the non-public company adoption date, i.e. annual periods starting after December 15, 2022. Early adoption is permitted. There are various transition methods available upon adoption. The Company is currently evaluating the impact of adoption on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which amends ASC 820 to add, remove, and modify fair value measurement disclosure requirements. New disclosures required for public companies under ASU 2018-13 include Level 3 changes in unrealized gains or losses and Level 3 range and weighted average used to develop significant unobservable inputs. ASU 2018-13 is effective for the Company beginning October 1, 2020, it is not expected that the adoption of this standard will have material effect on the Company’s consolidated financial statements.

In March 2020, the FASB issued ASU No. 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). The ASU provides optional expedients and exceptions for applying GAAP to transactions affected by reference rate (e.g., the London Inter-Bank Offer Rate) reform if certain criteria are met, for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The ASU is effective as of March 12, 2020 through December 31, 2022. The Company will evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis. The ASU is currently not expected to have a material impact on our consolidated financial statements.

Remaining performance obligations

The Company’s remaining performance obligations (“backlog”) represent the unrecognized revenue value of its contract commitments, which include deferred revenue and amounts that will be billed and recognized as revenue in future periods. The Company’s backlog may vary significantly each reporting period based on the timing of major new contract commitments and the backlog may fluctuate with currency movements. In addition, the Company’s customers have the right, under some circumstances, to terminate contracts or defer the timing of its services and their payments to the Company. As of September 30, 2020, the Company had $992,090 thousand of remaining performance obligations related to its battery storage product contracts, the majority of which we expect to recognize in revenue in the next 12 months. The Company also had $156,481 thousand of remaining performance obligations related to operational service contracts including maintenance, monitoring, and other minor services, of which we expect to recognize 35%

Guarantees

As of September 30, 2020 and 2019, the Company had outstanding bank guarantees issued as performance security arrangements for several projects. Performance security is a pre-condition to receive any payment from the customer and is reduced in stages according to the project completion status.

Typical turn-key contracts and long-term service agreements contain provisions for performance liquidated damages payments if the solution fails to meet the guaranteed performance thresholds at completion of the project or throughout the service agreement period.

Purchase Commitments

The Company has commitments for the minimum volumes of purchases of batteries under a master supply agreement effective as of December 23, 2019. As of September 30, 2020, the Company had future purchase commitments, primarily for batteries, as follows (in thousands):

Year 1	$	281,800

Liquidated damages apply if the minimum purchase volumes are not met. The Company expects to meet the minimum committed volumes of purchases. The Company ordered $128,888 thousand worth of batteries during the calendar year 2020 and exceeded the minimum purchase volume of the first calendar year of $79,250 thousand as defined by the mentioned master supply agreement.

Legal Contingencies

From time to time, the Company may be involved in litigation relating to claims that arise out of our operations and businesses and that cover a wide range of matters, including, among others, intellectual property matters, contract and employment claims, personal injury claims, product liability claims and warranty claims. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. It is reasonably possible that some matters could be decided unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that could be material. As of September 30, 2020, no estimate of reasonably possible losses can be determined.

In April 2019, one of the Company’s customers experienced a safety incident at one of its energy storage facilities which resulted in damage to the facility and injury to several first responders. The customer owned facility was delivered by and under warranty of AES Energy Storage and the Company was under contract to provide Operations and Maintenance (‘‘O&M’’) services to the facility. The Company, its customer, and the battery manufacturer, among others, have investigated the cause of the incident. As of June 2 2021, this safety incident has been fully resolved with all claims been settled. The Company did not incur any significant legal liabilities associated with the incident.

16.

Subsequent Events

The Company has evaluated subsequent events through June 24, 2021, which is the date that these consolidated financial statements were available to be issued.

During FY 2021, the Company spent approximately $18,000 thousand on an acquisition that will offer new capabilities and amplify and extend the Company’s energy storage product line. The acquisition represents a business combination. The valuation of acquired assets and liabilities is not completed as of the date these consolidated financial statements were available to be issued.

In October 2020, the Board of Directors of the Company approved an equity-based employee deferred compensation plan. On December 29, 2020 the Company amended their limited liability company agreement, the ‘‘Fluence—Amendment No. 2 to the Amended and Restated LLC Agreement’’ to (i) authorize a new class of Units designated as Class A-1 Units to be issuable upon the exercise of awards granted pursuant to the Equity Incentive Plans with distribution subject to the terms specified in the Agreement and (ii) effectuate the Unit Split and Reclassification of 1:1,320 per Unit.

On December 23, 2020, the Uncommitted Line of Credit was further amended to increase the aggregate borrowing amount to $50,000 thousand. On June 2, 2021, the expiration date for the Line of Credit was extended to March 31, 2023.

On December 27, 2020, the Company entered into a subscription agreement with QIA Florence Holdings LLC (‘‘QFH’’) for the issuance of 1,250,000 Class B units for a total value of $125,000 thousand. Following the completion of the transaction on June 9, 2021, AES, Siemens, and QFH hold 3,960,000,

F-22

TABLE OF CONTENTS

3,960,000, and 1,250,000 units, and 43.2%, 43.2%, and 13.6% of limited liability interests of the Company, respectively. Pursuant to the subscription agreement, QFH has certain rights that may allow it to cause the Company to repurchase the units at fair value five years from the completion of the transaction under conditions outside of the control of the Company. As of June 9, 2021, the Company has three Classes of Membership Interest units, Class A, Class A-1 and Class B. Additionally, Siemens contributed approximately $6,000 thousand in equity to the Company in exchange for certain amendments to the Company’s limited liability company agreement.

On April 28, 2021 AES and Siemens agreed to issue an aggregate of up to $120,000 thousand in principal amount under promissory notes to the Company.

On April 28, 2021 and June 3, 2021, the Company borrowed $25,000 thousand and $25,000 thousand from AES, respectively, in the form of one-year promissory notes, each bearing annual interest at 2.86%. On May 3, 2021, the Company borrowed $25,000 thousand from Siemens, in the form of a one-year promissory note with an annual interest rate of 2.86%. The proceeds were used for general working capital needs. As of June 22, 2021, the total $75,000 thousand in borrowings from AES and Siemens were paid off in full.

On April 28, 2021, the Company was notified of an emergency aboard a vessel carrying Fluence inventory while transiting through the Pacific Ocean. The vessel was reporting smoke coming from a cargo hold during severe weather and heavy seas. Based on an initial analysis of the exterior condition of the shipping containers, Fluence believes that some shipping containers came loose while at sea, and Fluence estimates a partial loss of cargo. The cargo in the damaged shipping containers had a value of approximately $30,000 thousand. Inspections of the cargo have not yet been completed and we cannot yet determine the actual amount of losses, including any potential insurance recoveries. Fluence has notified the marine cargo insurers of the incident and also notified each affected customer of this force majeure event, which under relevant supply contracts, provides Fluence an extension of the relevant schedule. If the incident ultimately was determined not to constitute a force majeure event, the Company estimates potential liquidated damages exposure of approximately $15,000 thousand.

Notes to Condensed Consolidated Financial Statements (Unaudited)

1. Organization and Operations

Fluence Energy, LLC (Fluence), a Delaware limited liability company, was formed on June 30, 2017, and commenced operations on January 1, 2018 (Effective Date). Fluence, with its wholly owned subsidiaries including Fluence Energy GmbH in Germany, Fluence Energy Pty Ltd. in Australia, and Fluence Energy Inc. in the Philippines, is primarily engaged in the construction and sale of battery-based energy storage products and provides related operational services. As of June 30, 2021, AES Grid Stability (“AES”) holds 3,960,000 Class A units, or 43.2% of our limited liability interest, Siemens Industry (“Siemens”) holds 3,960,000 Class A units, or 43.2% of our limited liability interest and Qatar Investment Authority (“QIA”) holds 1,250,000 Class B units, or 13.6% of our limited liability interests. Except where the content clearly indicates otherwise, “Fluence,” “we,” “us,” “our” or the “Company” refers to Fluence Energy, LLC and its wholly owned subsidiaries.

The Company’s chief operating decision maker (“CODM”) is its Chief Executive Officer. The Company’s CODM reviews financial information on a condensed consolidated basis for purposes of making operating decisions, allocating resources, and evaluating financial performance. As such, the Company has determined that it operates in one operating segment, which corresponds to one reportable segment.

2. Summary of Significant Accounting Policies and Estimates

Principles of Accounting and Consolidation

The accompanying condensed consolidated financial statements are prepared in accordance with U.S. generally accepted accounting principles (U.S. GAAP) and under the rules of the Securities and Exchange Commission (SEC). The accompanying condensed consolidated financial statements include the accounts of Fluence and its subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

Unaudited Interim Financial Information

The accompanying condensed financial statements as of June 30, 2021, and for the nine months ended June 30, 2021 and 2020 are unaudited. The unaudited interim financial statements have been prepared on the same basis as the audited annual financial statements and, in the opinion of management, reflect all adjustments, which include only normal recurring adjustments, necessary for the fair statement of the Company’s financial position as of June 30, 2021 and the results of its operations and its cash flows for the nine months ended June 30, 2021 and 2020. The financial data and other information disclosed in these notes related to the nine months ended June 30, 2021 and 2020 are also unaudited. The results for the nine months ended June 30, 2021 and 2020 are not necessarily indicative of results for the full year ending September 30, 2021 and 2020, any other interim periods, or any future year or period. The balance sheet as of September 30, 2020 included herein was derived from the audited financial statements as of that date. Certain disclosures have been condensed or omitted from the interim financial statements. These financial statements should be read in conjunction with the Company’s audited financial statements.

For a complete description of our significant accounting policies, refer to Note 2—Summary of Significant Accounting Policies and Estimates on our annual financial statements for the year ended September 2020. We include herein certain updates to those policies.

Business Combinations

We allocate acquisition price to the assets acquired and liabilities assumed based on their estimated fair values. The excess of acquisition price over fair value of the acquired assets and liabilities assumed is recorded as goodwill. Such valuations require management to make estimates and assumptions that affect the amounts reported in our unaudited condensed consolidated financial statements and accompanying notes. Actual results could differ from those estimates.

F-28

TABLE OF CONTENTS

Cash, Cash Equivalents, and Restricted Cash

Cash and cash equivalents include cash on-hand and highly liquid investments readily convertible to cash, with an original maturity of 90 days or less when purchased.

Cash restricted for use as a result of financing or other obligations is classified separately as restricted cash in other current assets.

The following table provides the components of cash, cash equivalents, and restricted cash as shown on the condensed consolidated statements of cash flows (in thousands):

	As of June 30,
	2021			2020
Cash and cash equivalents		$	58,497		$	38,972
Restricted cash included in other current assets			1,244			1,925
Total cash, cash equivalents and restricted cash		$	59,741		$	40,897

Restricted cash included in “Other current assets” on the condensed consolidated balance sheets as of June 30, 2021 consists of $923 thousand of collateral for credit card program (June 2020: $910 thousand) and $321 thousand of collateral for outstanding bank guarantees (June 2020: $1,015 thousand).

Revenue and Cost Recognition

Revenue from Digital Applications and Solutions: In October 2020, Fluence acquired the Advanced Microgrid Solutions (“AMS”) software and digital intelligence platform, which became the Fluence Trading Platform. Contracts involving the Fluence Trading Platform are generally entered into with commercial entities that control utility-scale storage and renewable generation assets. Fluence Trading Platform arrangements consist of a promise to provide access to proprietary cloud-based Software-as-a-Service (“SaaS”) to promote enhanced financial returns on the utility-scale storage and renewable generation assets. The Fluence Trading Platform is a hosted service that delivers automated, market-compliant bids to local electricity market operators. Customers do not receive legal title or ownership of the software as a result of these arrangements. The term for Fluence’s contracts with Trading Platform customers is generally 5 years, which may include certain renewal options to extend the initial contract term or certain termination options to reduce the initial contract term.

The Fluence Trading Platform is technology- and vendor-agnostic (i.e. it can be utilized for wind and solar assets as well as non-Fluence systems). The Fluence Trading Platform is separately identifiable from other promises that Fluence offers to its customers (i.e. it is not highly interrelated or integrated with other solutions). As such, Fluence determined that the Fluence Trading Platform is accounted for as a separate performance obligation. Revenue from the Fluence Trading Platform includes an integration fee and a monthly subscription fee. We consider the access to the Fluence Trading Platform and related support services in a customer contract to be a series of distinct services which comprise a single performance obligation because they are substantially the same and have the same pattern of transfer. We record amounts that have been invoiced in accounts receivable and in deferred revenue or revenues, depending on whether the revenue recognition criteria have been met.

Fair Value Measurements

F-29

TABLE OF CONTENTS

Unit-Based Compensation

Employees, directors, consultants and other independent contractors are eligible to receive equity awards and other forms of compensation under the 2020 Unit Option Plan (“the Option Plan”) and the Phantom Equity Incentive Plan (“the Incentive Plan”). Units awarded under the Option Plan are subject to a service condition and a performance condition (i.e. a liquidity event), as defined within the plan, both of which are required for vesting. Units awarded under the Incentive Plan vest subject to a liquidity event, as defined within the plan. As a liquidity event has not occurred, no compensation costs have been recorded under either plan in the periods presented.

The Company recognizes the costs associated with granting unit-based awards using a fair value-based measure in accordance with the requirements of Accounting Standards Codification 718, Compensation—Stock Compensation (ASC 718). The Company estimates the fair value of the unit-based awards, including unit options and phantom awards, using the Black-Scholes option-pricing model. Determining the fair value of unit-based awards requires the use of highly subjective assumptions, including the fair value of the unit underlying the award, the expected term of the award and expected unit price volatility.

The assumptions used in determining the fair value of unit-based awards represent management’s estimates, which involve inherent uncertainties and the application of management judgment. As a result, if factors change, and different assumptions are employed, unit-based compensation could be materially different in the future. The risk-free interest rates are based on the U.S. Treasury yield curve in effect at the time of grant, with maturities approximating the expected life of the unit options. The Company uses historical volatility of a selected group of guideline publicly traded entities as the expected volatility assumption.

The Company has made a policy election to account for forfeitures as they occur. If there are any modifications of the underlying invested securities or the terms of the unit option or phantom unit, it may be necessary to accelerate or increase any remaining unamortized unit-based compensation expense.

Earnings (Loss) per Unit

As of June 30, 2021, the Company has three Classes of Membership Interest units, Class A, Class A-1 and Class B. Earnings (loss) per unit is calculated and reported under the “two-class” method. The “two-class” method is an earnings allocation method under which earnings (loss) per unit is calculated for each class of common LLC member units considering both distributions declared or accumulated and participation rights in undistributed earnings as if all such earnings (loss) had been distributed during the period. Class B unit holders have a liquidation preference equal to their initial investment and do not have an obligation to fund losses of the business. When calculating the earnings (loss) per unit in the current period, the Class B units are not allocated any losses.

F-30

TABLE OF CONTENTS

The Company calculates basic earnings (loss) per common LLC member unit by dividing net income (loss) by the average number of common LLC member unit outstanding during the period, excluding Class B units because of their liquidation preference. Diluted earnings per unit is calculated after consideration of the potential dilutive effect of common LLC member unit equivalents on the average number of common LLC member units outstanding during the period. Dilution is not considered when a net loss is reported. Common LLC member unit equivalents that have an antidilutive effect are excluded from the computation of diluted earnings per common LLC member unit. As of June 30, 2021, the Company had common LLC member unit equivalents in the form of unit options and phantom units, as further discussed in Note 16—Unit-Based Compensation.

Unit Split

In December 2020, the Company approved an amendment to its Limited Liability Company Agreement to effect a 1:1,320 unit split of the Company’s Class A units, which was effected on December 29, 2020. The par value of the common unit was not adjusted as a result of the unit split. All common LLC member units and per unit data have been retrospectively revised to reflect the unit split.

Income Taxes

The Company recognizes the tax benefits from uncertain tax positions if it is more likely than not that the position will be sustained on examination by the taxing authorities. The Company recognizes interest and penalties related to unrecognized tax benefits as a component of income tax expense. For the nine months ended June 30, 2021 and June 30, 2020, the Company did not recognize tax benefits relating to uncertain tax positions.

Recent Accounting Pronouncements

In January 2017, the FASB issued ASU 2017-04, Simplifying the Test for Goodwill Impairment, which removes step 2 of the quantitative goodwill impairment test. Under the amended guidance, a goodwill impairment charge is recognized for the amount by which the carrying value of a reporting unit exceeds its fair value, not to exceed the carrying amount of goodwill. We adopted this standard on October 1, 2020. The adoption of the standard did not have a material impact on our financial statements.

In June 2018, the FASB issued ASU 2018-07, Compensation—Stock Compensation (Topic 718)—Improvements to Nonemployee Share-Based Payment Accounting. This update expands the scope of Topic 718, “Compensation—Stock Compensation,” to include equity-based awards granted to non-employees in exchange for goods or services. The accounting for employees and non-employees will be substantially aligned. We adopted this standard on October 1, 2020. The adoption of the standard did not have a material impact on our financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820)—Disclosure Framework—Changes to the Disclosure Requirements for Fair Value Measurement, which amends ASC 820 to add, remove, and modify fair value measurement disclosure requirements. New disclosures required for public companies under ASU 2018-13 include Level 3 changes in unrealized gains or losses and Level 3 range and weighted average used to develop significant unobservable inputs. We adopted this standard on October 1, 2020. The adoption of the standard did not have a material impact on our financial statements.

Recent Accounting Pronouncements Not Yet Adopted

In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842), which supersedes existing guidance on accounting for leases in ASC 840, Leases. This standard requires all leases to be recognized on

F-31

TABLE OF CONTENTS

the condensed consolidated balance sheet. ASU 2016-02 was effective for public companies for fiscal quarter beginning after December 15, 2018. As an EGC, Fluence is permitted to defer adoption until the non-public company adoption date, i.e., annual periods starting after December 15, 2021. Early adoption is permitted for all entities. The FASB has issued several amendments to ASU 2016-02, including ASU 2018-11, Leases (Topic 842)—Targeted Improvements that introduced an additional transition method permitting an entity to initially apply the new lease standard at the adoption date and recognize a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. ASU 2016-02 includes optional practical expedients intended to reduce the cost and complexity to implement the new lease standard, such as an option to maintain the current lease classification for all existing lease arrangements and the option to use hindsight in evaluating lessee options to extend or terminate a lease. The Company’s existing lease population is mainly comprised of operating leases for office space. The Company is currently evaluating the impact of adoption on its condensed consolidated financial statements, as well as the use of the practical expedients allowed under the standard.

In February 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses (Topic 326). This standard updates the impairment model for financial assets measured at amortized cost, known as the Current Expected Credit Loss (“CECL”) model. For trade and other receivables, held-to-maturity debt securities, loans and other instruments, entities will be required to use a new forward-looking “expected loss” model that generally will result in the earlier recognition of allowance for losses. ASU 2016-13 was effective for public companies for annual periods starting after December 15, 2019. As an EGC, Fluence is permitted to defer adoption until the non-public company adoption date, i.e., annual periods starting after December 15, 2022. Early adoption is permitted. There are various transition methods available upon adoption. The Company is currently evaluating the impact of adoption on its condensed consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. This guidance removes certain exceptions related to the approach for intraperiod tax allocations, the methodology for calculating income taxes in an interim period, and the recognition of deferred tax liabilities for outside basis differences. The guidance also clarifies and simplifies other areas of ASC 740. ASU 2019-12 was effective for public companies for fiscal years beginning after December 15, 2020, including interim periods therein. As an EGC, Fluence is permitted to defer adoption until the non-public company adoption date, i.e., annual periods starting December 15, 2021, and for interim periods beginning after December 15, 2022. Early adoption is permitted for all entities. Certain amendments must be applied on a prospective basis, certain amendments must be applied on a retrospective basis, and certain amendments must be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings/(deficit) in the period of adoption. The Company is currently evaluating the impact of adoption on its condensed consolidated financial statements.

In March 2020, the FASB issued ASU 2020-04, Facilitation of the Effects of Reference Rate Reform on Financial Reporting (Topic 848). The ASU provides optional expedients and exceptions for applying U.S. GAAP to transactions affected by reference rate (e.g., LIBOR) reform if certain criteria are met, for a limited period of time to ease the potential burden in accounting for (or recognizing the effects of) reference rate reform on financial reporting. The ASU is effective as of March 12, 2020 through December 31, 2022. The Company will evaluate transactions or contract modifications occurring as a result of reference rate reform and determine whether to apply the optional guidance on an ongoing basis. The ASU is currently not expected to have a material impact on our condensed consolidated financial statements.

Remaining Performance Obligations

As of June 30, 2021, we had $884,592 thousand of remaining performance obligations related to our battery storage product contracts, with respect to which we expect to recognize a majority of the revenue in the next 12 months. The Company also had $185,815 thousand performance obligations related to operational service contracts including maintenance, monitoring, and other minor services of which we expect to recognize 40% in revenue within the next five years and the remainder after five years, and $58,339 thousand remaining performance obligations related to capacity guarantees, 34% of which is expected to be recognized within the next five years and the remainder after five years. Our performance obligation related to digital application and solution contracts after we acquired the AMS software and digital intelligence platform is $2,540 thousand as of June 30, 2021, which we expect to recognize within the next five years.

Costs to Obtain or Fulfill a Contract

The Company recognizes the incremental costs incurred to obtain a contract with a customer as an asset when these costs are recoverable. These costs consist primarily of sales commissions.

As of June 30, 2021, the Company recorded costs to obtain a contract of $173 thousand (September 2020: $2,083 thousand) within “Other current assets” on the Company’s condensed consolidated balance sheets.

Amortization related to costs to obtain a contract was $1,392 thousand and $768 thousand for the nine months ended June 30, 2021 and 2020, respectively, which was recorded within sales and marketing on the Company’s condensed consolidated statements of operations and comprehensive loss.

4. Business Combinations

During October 2020, the Company acquired the assets and assumed the liabilities of a US based software and digital intelligence platform. The Company expects the acquisition will offer new capabilities, amplify and extend the Company’s energy storage product line, enabling customers to maximize the value of energy storage and renewables while accelerating grid decarbonization. The acquisition price of $18,000 thousand, all of which was fully paid with cash, which amount was adjusted for an immaterial amount to account for changes in net working capital adjustments. The acquisition represents a business combination. Fluence included the financial results of the acquisition in its condensed consolidated financial statements from the date of acquisition. Transaction costs associated with the acquisition were not significant and were expensed as incurred.

The following table summarizes the aggregate fair values and estimated useful lives of the assets acquired and liabilities assumed, as of the date of the acquisition (in thousands):

F-34

TABLE OF CONTENTS

	Fair Value			Estimated Useful Life
Intangible assets – Developed technology		$	12,600	12 years
Intangible assets – Customer relationships			780	6 years
Property and equipment			171	various
Goodwill			4,449
Cash paid for acquisition		$	18,000

The fair value of developed technology was determined using the multi-period excess earnings method as developed technology is considered to be the primary revenue-generating identifiable intangible asset acquired in the acquisition. The fair value assigned to assets acquired and liabilities assumed are based on management’s estimates and assumptions.

The goodwill is primarily attributed to the expanded market opportunities when integrating the acquired entity’s technology with the Company’s technology and the assembled workforce. Purchase accounting adjustments related to the acquisition have been completed.

The excess of the acquisition price over the fair value of assets acquired and liabilities assumed was recorded to goodwill. The Company expects such goodwill to be deductible for income tax purposes.

11. Income Taxes

The Company recorded $2,874 thousand of income tax expense and $5,678 thousand of income tax expense for the nine months ended June 30, 2021 and 2020, respectively. The Company’s estimated effective tax rate for the nine months ended June 30, 2021 and 2020 was (4.0)% and (14.2)%, respectively. For the nine months ended June 30, 2021 the Company’s effective tax rate differs from the statutory tax rate of 21% primarily due to foreign tax rate differentials, losses incurred by the partnership that flow through to the members, and valuation allowances recorded on foreign deferred tax assets. For the nine months ended June 30, 2020 the Company’s effective tax rate differs from the statutory rate of 21% primarily due to foreign tax rate differentials, losses incurred by the partnership that flow through to the members, valuation allowances recorded on foreign deferred tax assets and foreign withholding taxes on royalties.

F-37

TABLE OF CONTENTS

The Company does not believe it has any significant uncertain tax positions and therefore has no unrecognized tax benefits as of June 30, 2021 and September 30, 2020, that if recognized, would affect the annual effective tax rate.

As of June 30, 2021 and September 30, 2020, the Company had recorded a full valuation allowance against deferred tax assets of the Company’s German and Australian subsidiaries. The Company determined that based on the weight of available evidence, including cumulative losses, it is more-likely-than-not that the net deferred tax assets at its German and Australian entities will not be realized and recorded a valuation allowance against such deferred tax assets.

12. Commitments and Contingencies

The Company has certain contractual obligations incurred in the normal course of business that require fixed and determinable payments in the future. These commitments include lease obligations and purchase commitments under a master supply agreement.

The Company did not have significant changes in lease contracts during the nine months ended June 30, 2021.

Guarantees

As of June 30, 2021 and September 30, 2020, the Company had outstanding bank guarantees issued as performance security arrangements for several projects. Performance security is a pre-condition to receive any payment from the customer and is reduced in stages according to the project completion status.

Purchase Commitments

The Company has commitments for minimum volumes of purchases of batteries under a master supply agreement. Liquidated damages apply if the minimum purchase volumes are not met. The Company expects to meet the minimum committed volumes of purchases. The following presents our future minimum purchase commitments by fiscal year, primarily for batteries, and liquidated damages if the minimum purchase volumes are not met as of June 30, 2021(in thousands).

Legal Contingencies

From time to time, the Company may be involved in litigation relating to claims that arise out of our operations and businesses and that cover a wide range of matters, including, among others, intellectual property matters, contract and employment claims, personal injury claims, product liability claims and warranty claims. The Company accrues for litigation and claims when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. It is reasonably possible that some matters could be decided unfavorably to the Company and could require the Company to pay damages or make expenditures in amounts that could be material. The following discussion covers the Company’s potential loss contingencies as of June 30, 2021:

F-38

TABLE OF CONTENTS

2019 Safety Incident

In April 2019, one of the Company’s customers experienced a safety incident at one of its energy storage facilities which resulted in damage to the facility and injury to several first responders. The customer owned facility was delivered by and under warranty of AES Energy Storage and the Company was under contract to provide Operations and Maintenance (O&M) services to the facility. The Company, its customer, and the battery manufacturer, among others, have investigated the cause of the incident. As of June 24, 2021, this safety incident has been fully resolved with all claims being settled. The Company did not incur any significant legal liabilities associated with the incident.

2021 Cargo Loss Incident

On April 28, 2021, the Company was notified of an emergency aboard a vessel carrying Fluence inventory while transiting through the Pacific Ocean. The vessel was reporting smoke coming from a cargo hold during severe weather and heavy seas. Based on an initial analysis of the exterior condition of the shipping containers, Fluence believes that some shipping containers came loose while at sea, and Fluence estimates a partial loss of cargo. The cargo in the damaged shipping containers had a carrying value of approximately $30,000 thousand. Inspections of the cargo are in process. Based on the extent of the damage to the cargo in the containers holding Fluence inventory, we believe that the cargo in the moderately or severely damaged containers will not be usable. As of June 30, 2021, Fluence estimated a gross loss of $19,800 thousand based on our best estimate of the net realizable value of the cargo and has recorded an insurance receivable of $10,000 thousand related to non-disputed insurance claims that are probable of collection. The net loss of $9,800 thousand is recognized in “Cost of goods and service” in the consolidated statements of operations for the nine months ended June 30, 2021. However, our estimate of loss is subject to change upon new information that we expect to determine upon fully inspecting the inventory.

Fluence has notified the marine cargo insurers of the incident and also notified each affected customer of this event, which under relevant supply contracts, provides Fluence an extension of the relevant schedule due to the resulting battery supply delays. We believe this event qualifies as force majeure under our BESS contracts with our customers. However, if the incident ultimately was determined not to constitute a force majeure event, the Company estimates potential liquidated damages exposure of approximately $15,000 thousand. As of June 30, 2021, we have not adjusted the transaction price of our contracts with affected customers to include liquidated damages as a result of the cargo loss as none are expected.

13. Related-Party Transactions

Related parties are represented by AES, Siemens and QIA (collectively, “Members”), their respective subsidiaries and other entities under common control with Members.

14. Employee Benefit Plan

The Company maintains a 401(k) plan covering all eligible U.S. payroll employees. The 401(k) plan provides that eligible employees may make contributions subject to IRS limitations. Under terms of the 401(k) plan, the Company matches an employee’s contributions at a rate of 100% up to 5% of the employee’s annual salary. For the nine months ended June 30, 2021, the Company contributed approximately $1,296 thousand (2020: $777 thousand) to the 401(k) plan.

15. Unit-Based Compensation

In October 2020, the Board of the Company approved an equity-based employee deferred compensation scheme. The plan authorizes the Company to issue unit options and phantom units. The Compensation Committee of the Company’s Board of Directors determines the types of awards to be granted to individual participants as well as the terms and conditions of the awards. A summary of the unit-based awards granted during the nine months ended June 30, 2021 is presented below:

Unit Options

Unit options are granted with an exercise price equal to the fair value of the Company’s units at the date of grant. Unit option awards vest with the satisfaction of the following two criteria: (1) a service requirement of three years and (2) the occurrence of a liquidity event, such as a change in control or an initial public offering.

The fair value of each option is estimated on the date of grant using a Black-Scholes option valuation model that uses the assumptions noted in the following table:

Unit Price (reflects 10% discount for lack of marketability)		$32.56
Volatility		30%
Expected term	��	6 years
Risk-free Rate		1.14%
Exercise Price		$36.17

The expected volatility is based on the historical volatility of a selected group of guideline publicly traded entities over the most recent period corresponding to the expected life as of the grant date. The risk-free interest rate for periods during the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of valuation.

F-41

TABLE OF CONTENTS

During the nine months ended June 2021, we granted 873,490 class A-1 unit options to certain employees and non-employees which contain both service and performance vesting conditions. All options granted vest upon the satisfaction of both a service and a performance condition, if both conditions are met within 10 years. The grant date fair value of these options was $8.91 per option. Unit option awards granted to foreign employees and non-employee directors in certain countries will require cash settlement. The awards which require cash settlement are considered liability awards. The remainder of the options include a contingent cash settlement option outside the control of the holder and as such are considered equity awards.

The following table presents information concerning the outstanding options granted by the Company:

	Number (Units)		Weighted-Average Exercise Price (U.S. Dollars)			Aggregate Intrinsic Value (000s)		Weighted Average Estimated Useful Life (Years)
Outstanding – As of the inception of the Unit Option Plan		—			—				—
Options granted		873,490		$	36.17				6
Outstanding – As of June 30, 2021		873,490		$	36.17		—		6
Exercisable as of June 30, 2021		—			—		—		—

As of June 30, 2021, the Company has approximately $7,783 thousand unrecognized compensation expense related to unit options, which would be recognized commencing with the period in which the performance condition is deemed probable of achievement.

Phantom Units

During the nine months ended June 30, 2021, we granted 177,150 class A-1 phantom units, respectively, to certain employees and non-employees. All units granted vest upon the satisfaction of a performance condition, if the condition is met before the awards’ expiration date. The performance condition is satisfied upon the occurrence of a liquidity event, which is the earlier of either six months after the effective date of a registration statement for our IPO or a change in control. The grant date fair value of the phantom units was $32.56 per unit. Phantom units granted to foreign employees and non-employee directors in certain countries will require cash settlement. As such, the awards which require cash settlement are classified as liability awards. The remainder of the phantom units include a contingent cash settlement option outside the control of the holder and as such are classified as equity.

	Number (Units)		Weighted-Average Exercise Price ( U.S. Dollars)		Aggregate Intrinsic Value (000s)		Weighted Average Estimated Useful Life ( Years)

Units granted		177,150		—				2
Outstanding – As of June 30, 2021		177,150		—		5,768		2
Exercisable as of June 30, 2021		—		—				—

As of June 30, 2021, the Company has approximately $5,768 thousand unrecognized compensation expense related to phantom units, which would be recognized commencing with the period in which the performance condition is deemed probable of achievement.

As of June 30, 2021, the Company determined that the achievement of the performance condition was not probable and therefore, there was no expense recognized for these unit options or phantom units for the period ended June 30, 2021.

16. Mezzanine Equity

On December 27, 2020, the Company entered into a subscription agreement with Qatar Investment Authority for the issuance of 1,250,000 Class B units for a total value of $125,000 thousand. Following the

TABLE OF CONTENTS

completion of the transaction on June 9, 2021, AES, Siemens, and QIA hold 3,960,000, 3,960,000, and 1,250,000 units, and 43.2%, 43.2%, and 13.6% of limited liability interests of the Company, respectively. Pursuant to the subscription agreement, QIA has certain rights that may allow it to cause the Company to repurchase the units at fair value for five years from the completion of the transaction under conditions outside of the control of the Company. QIA’s redemption rights are contingent upon the Company not completing a qualified IPO within a specified time period. The Company does not consider QIA’s investment probable of becoming redeemable as it is not probable that the company will not complete a qualified IPO by the end of the IPO notice period, which is defined as nine months after QIA provides notice. QIA cannot provide notice until after five years after the effective date of the subscription agreement. This investment was initially recognized at fair value, which approximated the amount of proceeds received, net of issuance costs. At June 30, 2021 the investment is recognized at the carrying value, rather than the redemption value.

17. Collaborative Arrangement

In 2021, the Company executed a development agreement with a service provider to design integrated energy storage systems. Under the agreement, the Company makes periodic payments for development activities that will be performed over a three-year period. After development completion, the parties will each hold a license to commercialize certain products developed under the arrangement in exchange for annual royalty payments to the other party. We recorded $3,597 thousand of expense related to this agreement within research and development expense for the nine months ended June 30, 2021.

18. Subsequent Events

The Company has evaluated subsequent events through September 3, 2021, which is the date that these condensed consolidated financial statements were available to be issued.

Borrowing from Line of Credit

On July 23, August 4, August 11 and August 26, 2021, the Company borrowed $6,000 thousand, $22,000 thousand, $20,000 thousand, and $2,000 thousand, respectively, from its line of credit, to fund its working capital needs.

Borrowings from Related Parties

On August 11, 2021, the Company borrowed $25,000 thousand and $25,000 thousand from AES and Siemens, respectively, in the form of subordinated promissory notes, each bearing an annual interest at 2.86%. Each note has a maturity date within a year of its issuance.

Item 14. Indemnification of directors and officers.

Section 102(b)(7) of the General Corporation Law of the State of Delaware permits a corporation to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase or redemption in violation of Delaware corporate law or obtained an improper personal benefit. Our amended and restated certificate of incorporation provides that no director of Fluence Energy, Inc. shall be personally liable to it or its stockholders for monetary damages for any breach of fiduciary duty as a director, notwithstanding any provision of law imposing such liability, except to the extent that the General Corporation Law of the State of Delaware prohibits the elimination or limitation of liability of directors for breaches of fiduciary duty.

Section 145 of the General Corporation Law of the State of Delaware provides that a corporation has the power to indemnify a director, officer, employee, or agent of the corporation, or a person serving at the request of the corporation for another corporation, partnership, joint venture, trust or other enterprise in related capacities against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with an action, suit or proceeding to which he was or is a party or is threatened to be made a party to any threatened, ending or completed action, suit or proceeding by reason of such position, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his conduct was unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem proper.

Upon consummation of the Transactions, our amended and restated certificate of incorporation and amended and restated bylaws will provide indemnification for our directors and officers to the fullest extent permitted by the General Corporation Law of the State of Delaware. We will indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit or proceeding (other than an action by or in the right of us) by reason of the fact that he or she is or was, or has agreed to become, a director or officer, or is or was serving, or has agreed to serve, at our request as a

II-1

TABLE OF CONTENTS

director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (all such persons being referred to as an “Indemnitee”), or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees), judgments, fines, and amounts paid in settlement actually and reasonably incurred in connection with such action, suit, or proceeding and any appeal therefrom, if such Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable cause to believe his or her conduct was unlawful. Our amended and restated certificate of incorporation and amended and restated bylaws will provide that we will indemnify any Indemnitee who was or is a party to an action or suit by or in the right of us to procure a judgment in our favor by reason of the fact that the Indemnitee is or was, or has agreed to become, a director or officer, or is or was serving, or has agreed to serve, at our request as a director, officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys’ fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred in connection with such action, suit, or proceeding, and any appeal therefrom, if the Indemnitee acted in good faith and in a manner he or she reasonably believed to be in, or not opposed to, our best interests, except that no indemnification shall be made with respect to any claim, issue or matter as to which such person shall have been adjudged to be liable to us, unless a court determines that, despite such adjudication but in view of all of the circumstances, he or she is entitled to indemnification of such expenses. Notwithstanding the foregoing, to the extent that any Indemnitee has been successful, on the merits or otherwise, he or she will be indemnified by us against all expenses (including attorneys’ fees) actually and reasonably incurred in connection therewith. Expenses must be advanced to an Indemnitee under certain circumstances.

Prior to the consummation of this offering, we intend to enter into separate indemnification agreements with each of our directors and executive officers. Each indemnification agreement will provide, among other things, for indemnification to the fullest extent permitted by law against any and all expenses, judgments, fines, penalties, and amounts paid in settlement of any claim. The indemnification agreements will provide for the advancement or payment of all expenses to the indemnitee and for the reimbursement to us if it is found that such indemnitee is not entitled to such indemnification under applicable law and our amended and restated certificate of incorporation and amended and restated bylaws.

We maintain a general liability insurance policy that covers certain liabilities of directors and officers of our corporation arising out of claims based on acts or omissions in their capacities as directors or officers.

In any underwriting agreement we enter into in connection with the sale of Class A common stock being registered hereby, the underwriters will agree to indemnify, under certain conditions, us, our directors, our officers and persons who control us within the meaning of the Securities Act, against certain liabilities.

Item 15. Recent sales of unregistered securities.

The following sets forth information regarding securities sold or issued by the predecessors to the registrant in the three years preceding the date of this registration statement. No underwriters were involved in these sales. There was no general solicitation of investors or advertising, and we did not pay or give, directly or indirectly, any commission or other remuneration, in connection with the offering of these shares. In each of the transactions described below, the recipients of the securities represented their intention to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were affixed to the securities issued in these transactions.

(a) On June 21, 2021, Fluence Energy, Inc. agreed to issue 100 shares of common stock, par value $0.01 per share, which will be redeemed upon the consummation of the Transactions, to an officer of the Company in exchange for $1.00.

The offers, sales and issuances of the securities described above were deemed to be exempt from registration in reliance upon Section 4(a)(2) of the Securities Act or Rule 701 promulgated under Section 3(b) of the Securities Act as transactions between an issuer not involving any public offering within the meaning of Section 4(a)(2) of the Securities Act or pursuant to benefit plans and contracts relating to compensation as provided under Rule 701. The recipients in each of these transactions acquired the securities for investment only and not with a view to or for sale in connection with any distribution thereof.

Item 17. Undertakings.

(a)

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

(b)

Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of Fluence Energy, Inc. pursuant to the foregoing provisions, or otherwise, Fluence Energy, Inc. has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by Fluence Energy, Inc. of

II-4

TABLE OF CONTENTS

expenses incurred or paid by a director, officer or controlling person of Fluence Energy, Inc. in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, Fluence Energy, Inc. will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction, the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(c)

The undersigned registrant hereby further undertakes that:

(1)

For purposes of determining any liability under the Securities Act the information omitted from the form of prospectus filed as part of this registration statement in reliance upon Rule 430A and contained in a form of prospectus filed by Fluence Energy, Inc. pursuant to Rule 424(b)(1) or (4) or 497(h) under the Securities Act shall be deemed to be part of this registration statement as of the time it was declared effective.

(2)

For the purpose of determining any liability under the Securities Act each post-effective amendment that contains a form of prospectus shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
