All statements made in this Annual Report on Form 10-K that are not statements of historical fact, including statements about our beliefs and expectations and regarding future events or our future results of operations, financial condition, business, strategies, financial needs, and the plans and objectives of management, are forward-looking statements and should be evaluated as such. These statements often include words such as “anticipate,” “expect,” “suggests,” “plan,” “believe,” “intend,” “estimates,” “targets,” “projects,” “should,” “could,” “would,” “may,” “will,” “forecast” and other similar expressions or the negative of those terms. We base these forward-looking statements on our current expectations, plans and assumptions that we have made in light of our experience in the industry, as well as our perceptions of historical trends, current conditions, expected future developments and other factors we believe are appropriate under the circumstances at such time. As you read this Annual Report on Form 10-K, you should understand that these statements are not guarantees of future performance or results. The forward-looking statements are subject to and involve risks, uncertainties and assumptions, and you should not place undue reliance on these forward-looking statements. Although we believe that these forward-looking statements are based on reasonable assumptions at the time they are made, you should be aware that many factors could affect our business, results of operations and financial condition and could cause actual results to differ materially from those expressed in the forward-looking statements. Factors that may cause actual results to differ materially from current expectations include, but are not limited to:

• Our success and revenue growth depends on our ability to add and retain scaled customers and convert our scaled customers into super-scaled customers;

• We often have long sales cycles, which can result in significant time between initial contact with a potential customer and execution of a customer agreement, making it difficult to project when, if at all, we will generate revenue from those customers;

• We may experience fluctuations in our operating results, which could make our future operating results difficult to predict;

• If we do not manage our growth effectively, the quality of our platform and solutions may suffer, and our business, operating results and financial condition may be adversely affected;

• Our industry is intensely competitive, and if we do not effectively compete against current and future competitors or fail to innovate and make the right investment decisions in our product offerings and platform, our business, operating results and financial condition could be harmed;

• Future acquisitions or strategic investments could be difficult to identify and integrate, divert the attention of management and disrupt our business, dilute stockholder value and adversely affect our business, operating results and financial condition;

• The technology industry is subject to increasing scrutiny that could result in U.S. federal or state government actions that could negatively affect our business;

• Our business and the effectiveness of our platform depends on our ability to collect and use data online. New consumer tools, regulatory restrictions and potential changes to web browsers and mobile operating systems all threaten our ability to collect such data, which could harm our operating results and financial condition and adversely affect the demand for our products and solutions;

• Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely affect our business, results of operations and financial condition;

• Any unfavorable publicity or negative public perception of current data collection practices could result in additional regulations which may impact the effectiveness of our data cloud and platform;

• A significant inadvertent disclosure or breach of confidential and/or personal information we process, or a security breach of our or our customers’, suppliers’ or other partners’ IT Systems could be detrimental to our business, reputation, financial performance and results of operations;

• We depend on third-party data centers, systems and technologies to operate our business, the disruption of which could adversely affect our business, operating results and financial condition;

• If we fail to detect or prevent fraud or malware intrusion on our platform, devices, or systems, or into the systems or devices of our customers and their consumers, publishers could lose confidence in our platform, and we could face legal claims and regulatory investigations, any of which could adversely affect our business, operating results and financial condition;

• The standards that private entities and inbox service providers adopt in the future to regulate the use and delivery of email may interfere with the effectiveness of our platform and our ability to conduct business;

• Any actual or perceived failure to comply with evolving regulatory frameworks around the development and use of artificial intelligence could adversely affect our business, results of operations, and financial condition;

• Catastrophic events such as pandemics, earthquakes, flooding, droughts, fire and power outages, and business and operational interruption by man-made problems such as war, conflicts and acts of terrorism; and

• Other factors discussed in other sections of this Annual Report on Form 10-K, including the section titled “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

PART I

Item 1. Business.

Overview

Zeta is a leading omnichannel data-driven cloud platform that provides enterprises with consumer intelligence and marketing automation software. We empower our customers to target, connect and engage consumers through software that delivers personalized marketing across all addressable channels, including email, social media, web, chat, Connected TV (“CTV”) and video, among others. We believe our actionable insights derived from consumer intent enable our customers to acquire, grow and retain consumer relationships more efficiently and effectively than the alternative solutions available in the market.

Our Zeta Marketing Platform, or ZMP, is the largest omnichannel marketing platform with identity data at its core. The ZMP can analyze billions of structured and unstructured data points to predict consumer intent by leveraging sophisticated machine learning algorithms and the industry’s largest opted-in data set for omnichannel marketing. The ZMP acts on these insights by connecting with consumers through native integration of marketing channels and API integration with third parties. The ZMP’s data-driven algorithms and processes learn and optimize each customer’s marketing program in real time, producing a ‘flywheel effect’ that enables our customers to test, learn and improve their marketing programs in real time.

The ZMP empowers our customers to personalize consumer experiences at scale across multiple touchpoints. Marketing programs are created and orchestrated by our customers through automated workflows and sophisticated dashboards. Our Consumer Data Platform (“CDP+”) ingests, analyzes and distills disparate data points to generate a single view of a consumer, encompassing identity, profile characteristics, behaviors and purchase intent, which is then made accessible through a single console. Our Agile Intelligence suite (formerly known as Opportunity Explorer) synthesizes Zeta’s proprietary data and data generated by our customers to uncover consumer insights that are translated into marketing programs designed for highly targeted audiences across digital channels, including email, SMS, websites, applications, social media, CTV and chat.

We designed the ZMP using a flexible, service-oriented architecture in order to facilitate rapid development of new solutions, to meet evolving industry demands and to support new use cases and marketing requirements. The ZMP is hosted in the Zeta Hybrid Cloud, which is a unique pairing of a public cloud (AWS/Google/Azure) deployment and self-hosted private cloud (VMware/Docker/Kubernetes) resources designed to facilitate workload management in a cost-effective, performant and efficient manner.

We have also dedicated significant resources to the goal of building customer trust by developing and implementing programs designed to protect data privacy and to promote a secure technical environment. The resources we dedicated to this goal include engineers, analysts, lawyers, policy experts and operations specialists, as well as hardware and software from leading vendors and solutions we have designed and built. In particular, we have implemented a number of technical innovations, process enhancements and industry solutions in response to our increased obligations with respect to our data. For example, we can identify and implement user consent parameters and opt-in or opt-out as applicable and can evaluate whether such consents apply to our various data sources, products or customers.

The ZMP is built on the following four pillars:

1. Opted-in Data Set

Our data set is an amalgamation of our private proprietary data, publicly available data and data provided by our partner ecosystem.

Our data set contains more than 240 million opted-in individuals in the U.S. and more than 535 million opted-in individuals globally with an average of more than 2,500 attributes per individual, which may be demographic, behavioral, psychographic, transactional, or indicative of preference. On average, we ingest more than one trillion content consumption signals per month on a global basis and synthesize this information into hundreds of intent-based audiences, which can then be used to create marketing programs. All this data is managed through a proprietary database structure that has patented flexibility, speed and scalability.

2. Patented AI Engine

We believe our proprietary data is key to our AI engine. We analyze this data through extensive application of AI technologies, including machine learning, natural language processing, and generative AI. We leverage our AI technologies and data within the ZMP to:

• Seamlessly collect and ingest structured and unstructured data into the ZMP;

• Detect PII and apply data governance in accordance with business, state, and federal rules and regulations;

• Quickly and reliably analyze key consumer attributes and signals;

• Identify consumer intent by running sophisticated algorithms to analyze data;

• Cluster related concepts and prioritize actionable insights to create intent-based graphs;

• Create audiences comprised of individuals or affinity-driven clusters scored based on intent;

• Forecast experience-based outcomes at an individual and audience level;

• Personalize content to make experiences more relevant for the consumer and profitable for the enterprises; and

• Create channel and content recommendations to optimize marketing performance.

3. Omnichannel Engagement

Our platform provides integrated access to a wide range of omnichannel inventory and data sources, as well as third-party services and platforms. The ZMP integrates these third-party sources and services to enable our customers to deploy their targeted marketing programs through a wider range of channels, devices and formats, all within a single platform. This enables our customers to improve how they identify and engage the modern consumer who is using multiple devices and platforms (e.g., mobile, website, applications, social media, CTV and email).

4. Performance Optimization

Zeta’s platform provides real-time results to our customers through a graphical dashboard and makes recommendations for improvement through the same graphical interface. Our AI engineers continuously update the machine learning algorithms to improve the overall ROI for our customers.

Our Platform and Products

The ZMP is a single platform designed to enable enterprises to acquire, grow and retain consumer relationships more efficiently and effectively than alternative solutions available in the market. The platform consists of three core products (CDP, ESP, DSP) with modules that can be “turned on” to meet our customers’ specific business needs. Artificial intelligence is native to the ZMP, unlocking new capabilities for creativity, automation, optimization, forecasting, planning, and onboarding. Our customers can purchase our products individually or in combination based on their evolving needs. We also offer various technical upgrades, consulting services, additional integrations, and access to ad-hoc data sources, services, and channels. As a result, our customers are incentivized to allocate an increasing percentage of their marketing budgets to our platform and to enter long-term contractual commitments.

Messaging – ESP

Zeta Messaging, our ESP offering, provides our customers with end-to-end omnichannel messaging capabilities. From segmentation to automation of campaigns, we deliver rich, individualized experiences that drive engagement through email, mobile, social and other channels. Using access to our intelligence tools, our ESP customers can expand their knowledge of their customers with past purchase behavior, channel preferences, real-time interests, and predictive intent. Our built-in artificial intelligence not only selects audiences and automates campaigns, but it can also optimize content and recommendations dynamically, based on our intelligence-driven understanding of customer needs, interests, and forecasted behavior. As a component of the ZMP, Zeta Messaging offers integrated data management, enterprise-scale delivery and support, and sophisticated omnichannel orchestration. Our customers benefit from an account team committed to their success and backed by experts in strategy, content creation, data and analytics.

Data Management – CDP

Our customers can use Zeta CDP as their system of record for all consumer information. Zeta CDP delivers a single, actionable view of customers and prospects that include real-time identifiers and attributes. Customers can consolidate multiple databases and internal and external data feeds, and organize their data based on their unique needs and performance metrics. Enriched with intent-based scoring from our proprietary data, Zeta CDP makes it possible to identify anonymous website visitors and engage them across multiple channels with meaningful, individualized experiences. Zeta CDP has extensive technical flexibility and can adjust to custom data schemas with limited or no pre-configuration required. If necessary, we can also engineer a deeper level of data integration between Zeta CDP and a customer’s unique marketing infrastructure.

Activation - DSP

Zeta Activation aims to help our customers to maximize the power of paid media to engage the right audiences where and how they want to be reached, with personalized messages determined by billions of real-time signals and predictive insights. Zeta Activation delivers highly personalized, targeted experiences via desktop, mobile, CTV and social, among other channels. It operates on one of the industry’s most durable and persistent identity graphs, anchored by people-based identifiers with minimal reliance on third-party cookies. In turn, Zeta Activation provides more precise analytics and attribution, with zero-to-minimal data loss across channels, and can be used to intelligently optimize media spend. Through our single-platform approach, we can integrate paid media and multichannel campaigns to deliver true cross-channel marketing across desktop, mobile, display and video, CTV, search, email, and web, among other channels. We offer one of the largest proprietary data sets in the U.S., informing the campaigns that our customers launch with rich, actionable insights. Our superior integrated data management capabilities can update individual profiles with new data instantaneously.

Intelligence - Agile

Actionable intelligence is the foundation of the ZMP and our products. We showcase our differentiated capability to synthesize trillions of behavioral signals into intent-based scores tied to a unique individual through our Agile Intelligence product suite. Based on our proprietary data and uniquely modeled intender scores, our Agile Intelligence suite can present immediate and actionable opportunities within the ZMP that our customers can then use to generate growth. A closed-loop cycle from insight to activation enables our AI engine to quickly learn from the available data, identify the best data signals and create accurate and up-to-date Zeta Identity Graphs™. The Agile Intelligence suite is woven into the fabric of the ZMP and is accessible through five product modules: MarketPulse, CustomerPulse, DMAPulse, AudiencePulse and CompetitorPulse.

• MarketPulse provides marketers with real-time notifications and longitudinal visualizations representing changes in consumer sentiment and interest.

• CustomerPulse provides marketers with real-time, actionable insights across acquisition, retention and growth opportunities derived by enriching a customer’s data with Zeta data.

• DMAPulse provides marketers with real-time, actionable insights on designated market areas that should receive increased or decreased investments to optimize market share and customer acquisition efficiency.

• AudiencePulse provides marketers with real-time, actionable insights on more than 900 Zeta audiences predicting consumer intent and interest.

• CompetitorPulse providers marketers with actionable insights on the business’s competitive set and opportunities to capture market share and prevent customer attrition.

Our customers can use all five of the modules or choose any individual module to obtain data-cloud based insights on their existing consumers and prospects. We offer Agile Intelligence suite for a licensing fee and/or an incremental fee based on customers’ utilization of the ZMP. The terms of our subscription agreements are typically quarterly or annual.

Our Growth Strategies

Our data and AI-powered platform enables our customers to transform their digital marketing strategy, accelerate their revenue growth and enhance business returns. In turn, our customers’ success motivates them to increase their use of our platform, thereby accelerating our revenue and growth. Key elements of our long-term growth strategy include:

Further penetrate our existing customer base. We have customers spanning a wide spectrum of industry verticals and we believe we can achieve significant organic growth by cross-selling our existing solutions, making full use of our data capabilities and insights and by capturing an increased share of our scaled customers’ marketing spend by introducing new features and functionalities within the ZMP.

Acquire new scaled customers. We intend to aggressively pursue new scaled customers by investing in our sales and customer service teams while driving increased efficiencies in our go-to-market approach. We also intend to focus on converting our scaled customers into new super-scaled customers. The Agile Intelligence suite also serves as a sales accelerator to help acquire and grow new customers. We also have extensive relationships with many marketing agencies and enterprises and believe we can extend our platform to provide B2B marketing capabilities.

Continue to innovate and develop new products. With over 500 data scientists and engineers, we believe we are well positioned to quickly develop new products and take full advantage of the shift to digital marketing. Since we view data as one of our key competitive advantages, we will also continue to invest resources to expand our data offerings, both from third-party providers, as well as our proprietary data sources.

Continue to strengthen our partnership ecosystem and expand sales capacity. With a focus on growing our sales capacity, we are building a sophisticated sales operation to focus on opportunity creation and progression. We believe these new capabilities will allow us to further strengthen our relationships with our existing customers and gain global market share.

Expand into international markets. As we expand relationships with our existing customers in the U.S., we are also investing in select regions in Europe.

Our Key Strengths

Zeta’s competitive strengths historically have included the following:

Omnichannel Engagement

Through the ZMP, our customers are able to identify and target consumers across a wide range of digital channels. These channels can work independently, in parallel or in concert depending on the marketing strategies and tactics of our customers. Many of these channels, such as email and programmatic, are native to the ZMP, while others, such as social media, are accessed through API integrations with companies, such as Facebook and Snap.

Actionable Insights

Our customers can use the Agile Intelligence suite module in the ZMP to obtain and take action on high-value consumer insights in real-time. The ZMP monitors, aggregates and synthesizes the behaviors of individuals globally across multiple points of interactions to predict interest and intent.

Recognized Leader in Marketing Automation

We believe our customers choose our platform over others because of its powerful, integrated and easy to use applications, rapid integration with various channels and technologies, and seamless onboarding of our customers’ and third-party data. We have been recognized by various third-party research reports as a leader in the marketing automation sector such as in 2022, when we were recognized as a “Leader” in The Forrester Wave™: Email Marketing Service Providers, Q1 2022 and received the highest possible scores across eight criteria including innovation roadmap, market approach, content management, dynamic content, and measuring engagement. In addition, in 2023, we were named as a Leader in IDC’s MarketScape for Worldwide Omni-Channel Marketing Platforms for B2C Enterprises.

Secure, Scalable and Reliable Platform

The ZMP has been designed to provide our customers with high levels of reliability, data integrity, performance and security. We built and maintain a multi-tenant application architecture that has been designed to enable our service to scale securely, reliably and cost-effectively to tens of thousands of customers and millions of users. Our multi-tenant application architecture maintains the integrity and separation of customer data while still permitting all customers to use the same application functionality simultaneously. Our architecture also enables us to segment access privileges across our user base.

Our Customers

We work with some of the largest and most well-known enterprises across a wide spectrum of industry verticals including consumer & retail, telecommunications, financial services, business services and insurance, which contributed 17%, 15%, 10%, 10% and 6% of our revenues for the year ended December 31, 2023 and 12%, 12%, 13%, 11% and 8% of our revenues for the year ended December 31, 2022, respectively. 97% of our revenue for the year ended December 31, 2023 was derived from scaled customers, which we define as customers from which we have generated trailing-12-month revenue of at least $100,000. As a subset of scaled customers, we define super-scaled customers as customers from which we have generated trailing-12-month revenue of at least $1,000,000. We had 1,242 and 1,155 total customers, and 452 and 403 scaled customers, including 131 and 103 super-scaled customers, as of December 31, 2023 and 2022, respectively.

Competition

The markets for our products are characterized by intense competition, new industry standards, evolving distribution models, disruptive technology developments, frequent product introductions, short product life cycles, price cutting with resulting downward pressure on gross margins and price sensitivity on the part of customers. Our future success will depend on our ability to enhance and better integrate our existing products, introduce new products on a timely and cost-effective basis, meet changing customer needs, provide best-in-class data security to maintain customer confidence and combat cyber-attacks, extend our core technology into new applications and anticipate emerging standards, business models, software delivery methods and other technological changes.

We believe no single company has offerings that match the comprehensive capabilities of the ZMP and CDP+, but we face collective competition from a variety of companies. Our competitive market is highly fragmented with most competitors focused on specific use cases, end markets and/or types of data sets and point solutions. We believe the principal factors that drive competition between vendors in our market include:

• Quality of insights and analytics;

• Omnichannel automation;

• Real-time scoring and decisioning of data sets;

• Utility of data management tools;

• Comprehensive systems integration;

• Ease and speed of data ingestion and data onboarding; and

• Scale and scope of identity and audience data.

We believe we compete favorably across these factors. In particular, we believe the ZMP’s competitive advantages include:

• Intuitiveness and ease of use;

• Comprehensive feature set;

• Present workflows and automation;

• Rapid deployment;

• Flexibility and scalability;

• Seamless integration with a customer’s existing technologies; and

• Favorable customer ROI and total cost of ownership.

For additional information, see the section titled “Risk Factors—Risks Related to Our Business and Industry—Our industry is intensely competitive, and if we do not effectively compete against current and future competitors, our business, results of operations and financial condition could be harmed” and “Risk Factors— Risks Related to Data Collection and Security, Intellectual Property and Technology Industry Regulations— Our intellectual property rights may be difficult to enforce and protect, which could enable others to copy or use aspects of our technology without compensating us, thereby eroding our competitive advantages and having an adverse effect on our business, results of operations and financial condition.”

Seasonality

In general, the marketing industry experiences seasonal trends that affect the vast majority of participants in the digital marketing ecosystem. Historically, marketing activity is higher in the fourth quarter of the calendar year to coincide with the holiday shopping season as compared to the first quarter. As a result, the subsequent first quarter tends to reflect lower activity levels and lower performance. We generally expect these seasonality trends to continue and our ability to effectively manage our resources in anticipation of these trends may affect our operating results.

Data Privacy & Security Laws

Contemporary consumers use multiple platforms to learn about and purchase products, and have come to expect a seamless experience across all channels. This challenges marketing organizations to balance the demands of the consumer for a seamless experience with privacy-compliant methods of managing data and using such data to create these experiences. The global data protection landscape is rapidly evolving, and we are or may become subject to numerous state, federal and foreign laws, requirements and regulations governing the collection, use, disclosure, retention, and security of data. In the U.S., both Congress and state legislatures, along with federal regulatory authorities, have continued to increase their attention on the collection and use of consumer data, including as it relates to internet-based marketing. California has enacted broad-based privacy legislation, the California Consumer Privacy Act (“CCPA”), as supplemented by the subsequent California Privacy Rights Act (“CPRA”), which came into force in 2023. State legislatures outside of California have proposed dozens of data privacy bills similar to, but distinct from, the CCPA/CPRA, and new laws have been adopted in Colorado and Virginia which also came into force in 2023. We anticipate that, as with the CCPA/CPRA, new laws in the U.S. at either the state or federal level will generally allow personal information collection by businesses as the default, so long as data use practices are made transparent to consumers and consumer rights are honored when requested (opt-out model), with the exception of select classes of “sensitive data.” To date, despite significant legislative activity around privacy in the states and at the federal level, there have been no significant or credible efforts at legislation that would require prior consent before data is used (opt-in model), apart from sensitive data. Zeta believes that a continued emphasis on an opt-out regime in the U.S. will mean a continued ability to collect and use non-sensitive personal data at scale for marketing purposes.

Outside the U.S., the General Data Protection Regulation (“GDPR”) (and the UK equivalent, the United Kingdom GDPR (“UK GDPR”)) remain in force in Europe, and, overlaid with country-level laws implementing the ePrivacy Directive, continues to raise questions about the application of these laws to third-party marketing technology companies such as Zeta. Many non-U.S., non-EU jurisdictions have also enacted or are developing laws and regulations governing the collection and use of personal data, including Brazil, Canada, Japan, Singapore, India, South Africa and others. These laws represent a spectrum of opt-in vs. opt-out models, with the GDPR establishing the most stringent set of requirements for obtaining consumer consent. These requirements have served as barriers to the expansion of Zeta’s business in these markets; Zeta has created compliant solutions, but has not been able in some cases to achieve sufficient scale of data collection to create compelling business cases for customers in these markets.

Human Capital

We believe that our employees love working at Zeta because they believe that they are working towards a larger mission. We pride ourselves in hiring the best global talent with employees across the U.S. (including New York and Silicon Valley), the EU, the UK and India. As of December 31, 2023, we had 1,783 employees, including 955 employees located outside of the U.S. None of our U.S. employees are represented by a labor union with respect to their employment. We consider our relations with our employees to be good and have not experienced interruptions of operations or work stoppages due to labor disagreements.

Diversity, Equity and Inclusion

Zeta is devoted to and invested in living our commitment to diversity, equity and inclusion, which we know drives more collaboration, innovation, and better outcomes for teams and individuals. Representation at Zeta, and ensuring an inclusive workplace where all feel like they belong and can bring their true selves at work, is at the core of Zeta’s DEI strategy. We strive to empower all talent to excel as unique individuals, while also providing a forum to connect for everyone to learn from one another and celebrate our differences.

Zeta is focused on ensuring equitable processes, standards, and policies. We also create awareness around different backgrounds, cultures and communities through global panel discussions, volunteering and mentoring opportunities, as well as providing comprehensive trainings to all employees.

We currently have five Employee Resource Groups (ERGs) with strong engagement and participation: Bridge Builders (Black Community), WING (Women’s Community), PRIDE (LGBTQIA+ community), LiT (Latinx Community) and MOSIAC (AAPI Community). Each ERG also welcomes allies as we believe that creating meaningful change can only be achieved by working collectively as a united team.

Compensation, Benefits, and Employee Wellness

We aim to provide market-competitive compensation and benefit programs for our employees. To recruit and retain the best talent in a highly competitive marketplace, we routinely examine and refresh our compensation packages that may include salary, bonuses, sales commissions and equity. We believe by offering our full-time employees equity under our incentive award plan and providing an employee stock purchase plan, we can build a strong feeling of ownership and commitment to our shared long-term success.

In addition to our commitment to providing market-competitive compensation packages, we continue to look for ways to enhance our total rewards programs. Our full-time employees are offered medical, dental and vision insurance and life and disability insurance plans. These plans are designed to provide a comprehensive benefits package that is flexible and allows employees to maximize benefits based on individual needs. Furthermore, we provide the following programs, which vary by country/region: generous paid time off, family leave, flexible work schedules, and 401(k) matching.

Intellectual Property

We have a patent portfolio of more than 125 U.S. and international patents and applications which include 21 granted patents and 33 pending patent applications covering machine learning and artificial intelligence (AI). Our AI patents focus on integrating predictive personalization, outcome forecasting, and generative AI holistically throughout our products to increase efficiency, enhance user experience, and deliver better customer outcomes. Other aspects of our patent portfolio cover data governance, security, and management technology. Our key patents in these areas enhance the transferability and integrity of our data assets and the interoperability and scalability of our data platforms. We also currently own trademark registrations and applications for the ZETA and DISQUS names and variants thereof and other product-related marks in the United States and certain foreign countries. We have also registered numerous internet domain names related to our business. We also rely on copyright laws to protect creative aspects of our website and computer programs related to our platform and our proprietary technologies. In addition, we enter into confidentiality agreements and invention or work product assignment agreements with employees and contractors involved in the development of our proprietary intellectual property. We intend to pursue additional intellectual property protection to the extent we believe it would be beneficial and cost effective.

Item 1A. Risk Factors.

In addition to the other information set forth in this Annual Report on Form 10-K, you should carefully consider the risks and uncertainties described below, which could materially adversely affect our business, operating results, financial condition, and cash flow.

Summary of Risk Factors

We are providing the following summary of the risk factors contained in this Annual Report on Form 10-K to enhance the readability and accessibility of our risk factor disclosures. We encourage you to carefully review the full risk factors immediately following this summary as well as the other information in this report, including the section titled “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and our financial statements and related notes. The risks and uncertainties described in this Annual Report on Form 10-K may not be the only ones we face. If any of the risks actually occur, our business, operating results, financial condition, cash flows and prospects could be materially and adversely affected. These risks and uncertainties include, but are not limited to, the following:

• Our success and revenue growth depends on our ability to add and retain scaled customers and convert our scaled customers into super-scaled customers.

• We often have long sales cycles, which can result in significant time between initial contact with a potential customer and execution of a customer agreement, making it difficult to project when, if at all, we will generate revenue from those customers.

• We may experience fluctuations in our operating results, which could make our future operating results difficult to predict.

• If we do not manage our growth effectively, the quality of our platform and solutions may suffer, and our business, operating results and financial condition may be adversely affected.

• Our industry is intensely competitive, and if we do not effectively compete against current and future competitors or fail to innovate and make the right investment decisions in our product offerings and platform, our business, operating results and financial condition could be harmed.

• Future acquisitions or strategic investments could be difficult to identify and integrate, divert the attention of management and disrupt our business, dilute stockholder value and adversely affect our business, operating results and financial condition.

• The technology industry is subject to increasing scrutiny that could result in U.S. federal or state government actions that could negatively affect our business.

• Our business and the effectiveness of our platform depends on our ability to collect and use data online. New consumer tools, regulatory restrictions and potential changes to web browsers and mobile operating systems all threaten our ability to collect such data, which could harm our operating results and financial condition and adversely affect the demand for our products and solutions.

• Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely affect our business, results of operations and financial condition.

• Any unfavorable publicity or negative public perception of current data collection practices could result in additional regulations which may impact the effectiveness of our data cloud and platform.

• A significant inadvertent disclosure or breach of confidential and/or personal information we process, or a security breach of our or our customers’, suppliers’ or other partners’ IT Systems could be detrimental to our business, reputation, financial performance and results of operations.

• We depend on third-party data centers, systems and technologies to operate our business, the disruption of which could adversely affect our business, operating results and financial condition.

• If we fail to detect or prevent fraud or malware intrusion on our platform, devices, or systems, or into the systems or devices of our customers and their consumers, publishers could lose confidence in our platform, and we could face legal claims and regulatory investigations, any of which could adversely affect our business, operating results and financial condition.

• The standards that private entities and inbox service providers adopt in the future to regulate the use and delivery of email may interfere with the effectiveness of our platform and our ability to conduct business.

• Any actual or perceived failure to comply with evolving regulatory frameworks around the development and use of artificial intelligence could adversely affect our business, results of operations, and financial condition.

• Catastrophic events such as pandemics, earthquakes, flooding, droughts, fire and power outages, and business and operational interruption by man-made problems such as war, conflicts and acts of terrorism.

Risks Related to Our Business and Our Industry

Our success and revenue growth depends on our ability to add and retain scaled customers.

Our success is dependent on regularly adding new customers, in particular new scaled customers, and increasing our existing customers’ usage of our platform in order to convert our scaled customers into super-scaled customers. We also continually work on converting our non-scaled customers into scaled customers. Many of our contracts and relationships with customers do not include automatic renewal or exclusive obligations requiring them to use our platform or maintain or increase their use of our platform. Our customers, in particular our scaled customers, typically have relationships with numerous providers and can use both our platform and those of our competitors without incurring significant costs or disruption. Our customers may also choose to decrease their overall marketing spend for any reason, including if they do not believe they are generating a sufficient return on their marketing spend. Further, we may not be successful at educating and training our new and existing customers on how to use our platform, in particular our advanced reporting tools, in order for them to benefit from it and generate revenues. Accordingly, we must continually work to win new scaled customers and educate and retain existing scaled customers, increase their usage of our platform and capture a larger share of their marketing spend, which may lead to an increase in our super-scaled customers.

In 2023, our top ten customers accounted for approximately one-third of our total revenue and no customer accounted for more than 10% of our total revenue. Occasionally, we enter into separate contracts and billing relationships with individual marketing agencies that are owned by the same holding company and account for them as separate customers. However, if a holding company of multiple marketing agencies chooses to exert control over the individual agencies in the future and terminate their relationship with us, it could result in a disproportionate loss of revenue.

A substantial portion of our revenue is derived from usage-based pricing, which is less stable than subscription-based pricing. If our customers, in particular our scaled customers, decide not to continue to use our platform or decrease their usage of our platform for any reason, or if we fail to attract new customers and turn them into scaled customers or super-scaled customers, our revenue could decline, which would materially and adversely harm our business, operating results and financial condition. We cannot assure that our scaled customers will continue to use and increase their spend on our platform or that we will be able to attract a sufficient number of new scaled customers to continue to grow our revenue. If scaled customers representing a significant portion of our business decide to materially reduce their use of our platform or cease using our platform altogether, our revenue could be significantly reduced, which could have a material adverse effect on our business, operating results and financial condition. We may not be able to replace scaled customers who decrease or cease their usage of our platform with new scaled customers that will use our platform to the same extent.

We often have long sales cycles, which can result in significant time between initial contact with a potential customer and execution of a customer agreement, making it difficult to project when, if at all, we will obtain new customers and when we will generate revenue from those customers.

As part of our sales efforts, we invest considerable time and expense evaluating the specific organizational needs of our potential customers and educating these potential customers about the technical capabilities and value of our platforms and solutions. We may spend substantial time and resources prospecting for new business or responding to requests for proposals from potential customers, and these efforts may not result in us ultimately generating any revenue from a potential customer. It is possible that we will be unable to recover any of these expenses.

Our results of operations also depend on sales to enterprise customers, which make product purchasing decisions based in part or entirely on factors, or perceived factors, not directly related to the features of our platform, including, among others, a customer’s projections of business growth, uncertainty about economic conditions, capital budgets, anticipated cost savings from the implementation of our platform, potential preference for such customer’s internally-developed software solutions, perceptions about our business and platform, more favorable terms offered by potential competitors, and previous technology investments. As a result of these and other factors, there can be no assurance that we will be successful in making a sale to a potential customer. If our sales efforts to a potential customer do not result in sufficient revenue to justify our investments, our business, operating results and financial condition could be adversely affected.

We are subject to payment-related risks if customers dispute, do not pay their invoices, or decrease their amount of spend due to unforeseen downturns in their financial condition. Any decreases or significant delays in payments could have a material adverse effect on our business, operating results and financial condition. These risks may be heightened during economic downturns or customer impacts from such downturns, including supply chain disruptions or shortages.

We may become involved in disputes with our customers over the operation of our platform, the terms of our agreements or our billings for purchases made by them through our platform. In the past, certain customers have sought to slow their payments to us or been forced into filing for bankruptcy protection, resulting in delay or cancelation of their pending payments to us. In certain cases, customers have been unable to timely make payments, and we have suffered losses. Certain of our contracts with marketing agencies state that if their customer does not pay the agency, the agency is not liable to us, and we must seek payment solely from their customer, a type of arrangement called sequential liability. Contracting with these agencies, which in some cases have or may develop higher-risk credit profiles, may subject us to greater credit risk than if we were to contract directly with the customer.

If we are unable to collect customers’ fees on a timely basis or at all, we could incur write-offs for bad debt, which could have a material adverse effect on our business, operating results and financial condition for the periods in which the write-offs occur. In the future, bad debt may exceed reserves for such contingencies, and our bad debt exposure may increase over time. Even if we are not paid by our customers on time or at all, we may still be obligated to pay for the inventory we have purchased for our customers’ marketing campaigns, and consequently, our results of operations and financial condition would be adversely impacted.

We may experience fluctuations in our operating results, which could make our future operating results difficult to predict.

Our quarterly and annual operating results have fluctuated in the past, and we expect our future operating results to fluctuate due to a variety of factors, many of which are beyond our control. Our liquidity and revenue can fluctuate quarter to quarter as certain of our customers have seasonal marketing activity. Historically, marketing activity is higher in the fourth quarter of the calendar year to coincide with the holiday shopping season as compared to the first quarter. As a result, the subsequent first quarter tends to reflect lower activity levels and lower performance. The varying nature of our pricing mix between periods, customers and products may also make it more difficult for us to forecast our future operating results. Further, these factors may make it more difficult to make comparisons between prior, current and future periods. As a result, period-to-period comparisons of our operating results should not be relied upon as an indication of our future performance.

In addition, the following factors may cause our operating results to fluctuate:

• Our usage-based pricing model makes it difficult to forecast revenues from our current customers and future prospects;

• changes in our pricing policies, the pricing policies of our competitors and the pricing or availability of data or other third-party services;

• the seasonal budgeting cycles and internal marketing budgeting and strategic purchasing priorities of our customers;

• our ability to retain and attract top talent;

• our ability to anticipate or respond to changes in the competitive landscape, or improvements in the functionality of competing solutions that reduce or eliminate one or more of our competitive advantages;

• our ability to maintain and expand our relationships with data centers and strategic third-party technology vendors, who provide floor space, bandwidth, cooling and physical security services on which our platform operates;

• our ability to successfully expand our business internationally;

• the emergence of significant privacy, data protection, security or other threats, regulations or requirements applicable to our business and shifting views and behaviors of consumers concerning use of data and data privacy;

• extraordinary expenses, such as litigation or other dispute-related settlement payments; and

• future accounting pronouncements or changes in our accounting policies.

Any one of the factors referred to above or herein or the cumulative effect of any combination of factors referred to above or herein may result in our operating results being below our expectations and the expectations of securities analysts and investors, or may result in significant fluctuations in our quarterly and annual operating results, including fluctuations in our key performance indicators ("KPIs"). This variability and unpredictability could result in our failure to meet our business plan or the expectations of securities analysts or investors for any period. In addition, a significant percentage of our operating expenses are fixed in nature in the short term and based on forecasted revenue trends. Accordingly, in the event of revenue shortfalls, we are generally unable to mitigate the negative impact on our results of operations in the short term.

If we do not manage our growth effectively, the quality of our platform and solutions may suffer, and our business, operating results and financial condition may be adversely affected.

The continued growth in our business may place demands on our infrastructure and our operational, managerial, administrative and financial resources. Our success will depend on the ability of our management to manage growth effectively. Among other things, this will require us at various times to:

• strategically invest in the development and enhancement of our platform and data center infrastructure;

• improve coordination among our engineering, product, operations and other support organizations;

• manage multiple relationships with various partners, customers and other third parties;

• manage international operations;

• develop our operating, administrative, legal, financial and accounting systems and controls; and

• recruit, hire, train and retain personnel, especially those possessing extensive engineering skills and experience in complex technologies and data sciences, of which there is limited supply and increasing demand.

If we do not manage our growth well, the efficacy and performance of our platform may suffer, which could harm our reputation, reduce demand for our platform and solutions and have an adverse effect on our business, operating results and financial condition.

Our industry is intensely competitive, and if we do not effectively compete against current and future competitors or fail to innovate and make the right investment decisions in our product offerings and platform, our business, operating results and financial condition could be harmed.

Our industry is intensely competitive. To sustain and grow our revenue, we must continuously respond to the different trends driving our industry. We generally have flexible master services agreements in place with our customers. Such agreements allow our customers to change the amount of spend through our platform or terminate our services with limited notice. As a result, the introduction of new entrants or technology that are superior to or that achieve greater market acceptance than our products and solutions could negatively impact our revenue. In such an event, we may experience a reduction in market share and may have to respond by reducing our prices, resulting in lower profit margins for us.

There has also been rapid evolution and consolidation in the marketing technology industry, and we expect this trend to continue. Larger companies typically have more assets to purchase emerging companies or technologies, which gives them a competitive edge. If we are not able to effectively compete with these consolidated companies, we may not be able to maintain our market share and may experience a reduction in our revenue.

Our industry is subject to rapid and frequent changes in technology, evolving customer needs and the frequent introduction of new and enhanced offering by our competitors, making it intensely competitive. To sustain and grow our revenue, we must continuously respond to the different trends driving our industry. We must regularly make investment decisions regarding offerings and technology to maintain the technological competitiveness of our products and platform and meet customer demand and evolving industry standards. As we continue to grow and attract a broader customer base, we will have to invest more time and effort to maintain a certain level of performance in our products and platform.

The complexity and uncertainty regarding the development of new technologies and the extent and timing of market acceptance of innovative products and solutions create difficulties in maintaining this competitiveness. The success of any enhancement or new solution depends on many factors, including timely completion, adequate quality testing, appropriate introduction and market acceptance. If our competitors are able to orientate their product to meet the specific needs of a particular industry better than us, they may be able to amass market share faster than us and by consequence, reduce our current and future revenues.

Without the timely introduction of new products, solutions and enhancements, our offerings could become technologically or commercially obsolete over time, or we may be required to make unanticipated and costly changes to our platform or business model, in which case our revenue and operating results would suffer. New customer demands, superior competitive offerings or new industry standards could require us to make unanticipated and costly changes to our platform or business model. If we fail to enhance our current products and solutions or fail to develop new products to adapt to our rapidly changing industry or to evolving customers’ needs, demand for our platform could decrease and our business, operating results and financial condition may be adversely affected.

Our use and reliance upon technology and development resources in India may expose us to unanticipated costs and liabilities, which could affect our ability to realize cost savings from our technology operations in India and other non-U.S. locations.

We conduct a significant amount of our technology and product development work in India and other global locations. We cannot ensure that our reliance upon development resources in India and other non-U.S. locations will enable us to achieve meaningful cost reductions or greater resource efficiency. Further, our operations in India involve significant risks, including:

• difficulty hiring and retaining engineering and management resources due to intense competition for such resources and resulting wage inflation;

• heightened exposure to changes in economic, security and political conditions, war, conflicts and acts of terrorism;

• different standards of protection for intellectual property rights and confidentiality protection;

• the effects of pandemics, epidemics or other health crises on general health and economic conditions; and

• fluctuations in currency exchange rates and tax compliance.

The enforcement of intellectual property rights and confidentiality protections in India may not be as effective as in the U.S. or other countries. Policing unauthorized use of proprietary technology is difficult and expensive and we might need to resort to

litigation to protect our trade secrets and confidential information. The experience and capabilities of Indian courts in handling intellectual property litigation vary, and outcomes are unpredictable. Further, such litigation may require significant expenditure of cash and management efforts and could harm our business, operating results and financial condition. An adverse determination in any such litigation will impair our intellectual property rights and may harm our business, operating results and financial condition.

We expect to continue to rely on significant cost savings obtained by concentrating our technology and development and engineering work in India and other non-U.S. locations, but difficulties resulting from the factors noted above and other risks related to our operations in India or such other non-U.S. locations could increase our expenses and harm our competitive position. The historical rate of wage inflation has been higher in India than in the U.S. In addition, if the Rupee strengthens against the U.S. Dollar, our costs would increase. If the cost of technology and development work in India significantly increases or the labor environment in India changes unfavorably, our cost savings may be diminished. Any such developments could adversely affect our business, operating results and financial condition.

Our success depends on our ability to retain key members of our management team, and on our ability to hire, train, retain and motivate new employees.

Our success depends upon the continued service of members of our senior management team and other key employees. Our Co-Founder and Chief Executive Officer, David Steinberg, is critical to our overall management, as well as the continued development of our platform, relationships with our customers and vendors and our overall strategic direction. We do not maintain “key person” insurance for any member of our senior management team or any of our other key employees. Our senior management and key personnel are all employed on an at-will basis, which means that they could terminate their employment with us at any time, for any reason and without notice. In addition, some of our key employees may receive significant proceeds from sales of our Class A common stock, which may reduce their motivation to continue to work for us. As a result, we may be unable to retain them, which could make it difficult to operate our business, cause us to lose expertise or know-how and increase our recruitment and training costs.

Our success also depends on our ability to hire, train, retain and motivate new employees. We have incurred substantial stock-based compensation expense and will continue to incur stock-based compensation expense in future years as a result of our equity compensation plan under which we grant time-based and performance-based restricted stock awards. Competition for employees in our industry can be intense, and we compete for experienced personnel with many companies that have greater resources than we have. The market for engineering talent is particularly intense in New York, where we are headquartered and in the San Francisco Bay Area, the EU and India where we have offices. Our future growth will also depend in part on our ability to establish sales teams that effectively solve problems and efficiently execute our objectives. We will need to establish teams that are well versed in complex and varied systems of distribution across national, regional and international markets. We believe that there is significant competition for sales personnel with the sales skills and technical knowledge that we require. Our ability to achieve growth in revenue in the future will depend, in large part, on our success in recruiting, training and retaining sufficient numbers of sales personnel with relevant industry knowledge and strong selling skills.

We believe our corporate culture has been critical to our success and we plan to continue to invest time and resources to continue building it. In particular, Diversity, Equity and Inclusion (“DEI”) is a strategic imperative at Zeta. Our DEI team is focused on driving inclusiveness, innovation and stronger business results by attracting a more diverse talent pool and creating a more inclusive work environment for all our employees around the world. Although we have adopted policies to promote compliance with laws and regulations as well as to foster a respectful workplace for all employees, our employees may fail to abide by these policies. In addition to damaging our reputation, actual or alleged misconduct could affect the confidence of our stockholders, regulators and other parties and could have a material adverse effect on our business, operating results and financial condition.

Future acquisitions or strategic investments could be difficult to identify and integrate, divert the attention of management and disrupt our business, dilute stockholder value and adversely affect our business, operating results and financial condition.

As part of our growth strategy, we may acquire or invest in other businesses, assets or technologies that are complementary to and fit within our strategic goals. Acquisitions are inherently risky and if they fail, they can result in costly remediating steps such as litigation and divesture. Any acquisition or investment may divert the attention of management and require us to use significant amounts of cash, issue dilutive equity securities or incur debt. The anticipated benefits of any acquisition or investment may not be realized, and we may be exposed to unknown risks, any of which could adversely affect our business, operating results and financial condition, including risks arising from:

• difficulties in integrating the operations, technologies, product or service offerings, administrative systems and personnel of acquired businesses, especially if those businesses operate outside of our core competency or geographies in which we currently operate;

• ineffectiveness or incompatibility of acquired technologies or solutions;

• potential loss of key employees of the acquired businesses;

• inability to maintain key business relationships and reputations of the acquired businesses;

• diversion of management attention from other business concerns;

• litigation arising from the acquisition or the activities of the acquired businesses, including claims from terminated employees, customers, former stockholders or other third parties and intellectual property disputes;

• assumption of contractual obligations that contain terms that are not beneficial to us, require us to license or waive intellectual property rights, or increase our risk of liability;

• complications in the integration of acquired businesses or diminished prospects;

• failure to generate the expected financial results related to an acquisition on a timely manner or at all;

• weak, ineffective, or incomplete data privacy compliance strategies by the acquired company resulting in our inability to use acquired data assets;

• failure to accurately forecast the financial or other business impacts of an acquisition; and

• implementation or remediation of effective controls, procedures and policies for acquired businesses.

To fund future acquisitions, we may pay cash, which would diminish our cash reserves, or issue additional shares of our Class A common stock, which could dilute current stockholders’ holdings in our company. Borrowing to fund an acquisition would result in increased fixed obligations and could also subject us to covenants or other restrictions that could limit our ability to effectively run our business.

We may be adversely affected by the effects of inflation.

Inflation has the potential to adversely affect our liquidity, business, operating results and financial condition of operations by increasing our overall cost structure, particularly if we are unable to achieve commensurate increases in the prices we charge our customers. The existence of inflation in the economy has resulted in, and may continue to result in, higher interest rates and capital costs, increased costs of labor, weakening exchange rates and other similar effects. As a result of inflation, we have experienced and may continue to experience, cost increases. Although we may take measures to mitigate the impact of this inflation, if these measures are not effective, our business, operating results, financial condition and liquidity could be materially adversely affected. Even if such measures are effective, there could be a difference between the timing of when these beneficial actions impact our results of operations and when the cost of inflation is incurred.

Our international operations subject us to additional costs and risks, and may not yield returns, and our continued international expansion may not be successful.

We have entered into several international markets and expect to enter into additional markets in the future. We expect to continue to expand our international operations, which may require significant management attention and financial resources and may place burdens on our management, administrative, operational, legal and financial infrastructure. The costs and risks inherent in conducting business internationally include:

• difficulty and costs associated with maintaining effective controls at foreign locations;

• adapting our platform and solutions to non-U.S. customer preferences and customs;

• difficulties in staffing and managing foreign operations;

• difficulties in enforcing our intellectual property rights;

• new and different sources of competition;

• regulatory and other delays and difficulties in setting up foreign operations;

• compliance with anti-bribery laws, such as the U.S. Foreign Corrupt Practices Act and the United Kingdom (“UK”) Anti-Bribery Act 2010, by us, our employees and our business partners;

• compliance with export and import control and economic sanctions, laws and regulations, such as those administered by the U.S. Office of Foreign Assets Control;

• compliance with foreign data privacy laws, such as the EU ePrivacy Directive, GDPR, UK data protection laws, and Brazil’s General Data Protection Law (“LGPD”), which could materially diminish our ability to collect data and/or the effectiveness of our platform;

• restrictions on the transfers of funds;

• currency exchange rate fluctuations and foreign exchange controls;

• economic and political instability in some countries;

• compliance with the laws of numerous taxing jurisdictions where we conduct business, potential double taxation of our international earnings, and potentially adverse tax consequences due to changes in applicable U.S. and foreign tax laws; and

• the complexity and potential adverse consequences of U.S. tax laws as they relate to our international operations.

As we continue to expand our business globally, our success will depend, in large part, on our ability to anticipate and effectively manage these risks. These factors and others could harm our ability to increase international revenues and, consequently, could adversely affect our business, operating results and financial condition. The expansion of our existing international operations and entry into additional international markets will require significant management attention and financial resources. Our failure to manage these risks successfully could adversely affect our business, operating results and financial condition.

Our business is subject to the risk of catastrophic events such as pandemics, earthquakes, flooding, droughts, fire and power outages, and to business and operational interruption by man-made problems such as war, conflicts and terrorism.

Our business is vulnerable to damage or interruption from pandemics, earthquakes, extreme weather events, flooding, droughts, fire, power outages, telecommunications failures, terrorist attacks, acts of war, human errors, break-ins and similar events. A significant natural disaster could have a material adverse effect on our business, operating results, and financial condition, and our insurance coverage may be insufficient to compensate us for losses that we may incur. As we rely heavily on our data center facilities, computer and communications systems and the Internet to conduct our business and provide high-quality customer service, any disruptions of the foregoing could negatively impact our ability to run our business and either directly or indirectly disrupt publishers’ and partners’ businesses, which could have an adverse effect on our business, operating results, and financial condition.

In particular, the COVID-19 pandemic, including the reactions of governments, markets and the general public, resulted in a number of adverse consequences for our business, operating results, and financial condition, many of which were beyond our control. Any resurgences or variants of the virus or other epidemics, pandemics or health crises could have a material negative impact on economic and market conditions around the world, which could have a significant negative impact on our and our customers, suppliers’ or other partners’ business, operating results, and financial condition. Actual or threatened war, terrorist activity, political unrest, civil strife, and other geopolitical uncertainty could have a similar effect on our and our customers, suppliers’ or other partners’ business, financial condition or growth strategy.

Risks Related to Data Collection and Security, Intellectual Property and Technology Industry Regulations

The technology industry is subject to increasing scrutiny that could result in U.S. government actions that could negatively affect our business.

We may face claims relating to the information or content that is made available through our platform. Though we contractually require our customers to represent that they will follow our policies with respect to all information or content they upload to our systems, we may be exposed to potential liability if our customers do not abide by such policies. In particular, the nature of our business may expose us to claims related to defamation, dissemination of misinformation or news hoaxes, discrimination, harassment, intellectual property right infringement, rights of publicity and privacy, personal injury torts, laws regulating hate speech or other types of content, and breach of contract, among others. The technology industry is subject to intense media, political and regulatory scrutiny, including on issues related to antitrust and artificial intelligence, which exposes us to government investigations, legal actions and penalties. For instance, various regulatory agencies, including competition and consumer protection authorities, have active proceedings and investigations concerning multiple technology companies on antitrust and other issues. If we become subject to such investigations, we could be liable for substantial fines and penalties, be required to change our products or alter our business operations, receive negative publicity, or be subject to civil litigation, all of which could harm our business. Lawmakers also have proposed new laws and regulations, and modifications to existing laws and regulations, that affect the activities of technology

companies such as the recent efforts to eliminate or modify Section 230 of the Communications Decency Act. If such laws and regulations are enacted or modified, they could negatively impact us, even if they are not specifically intended to affect our company. In addition, the introduction of new products, expansion of our activities in certain jurisdictions, or other actions that we may take may subject us to additional laws, regulations and other scrutiny. The increased scrutiny of certain acquisitions in the technology industry also could affect our ability to enter into strategic transactions of our own or to acquire other businesses.

Compliance with new or modified laws and regulations could increase the cost of conducting our business, limit the opportunities to increase our revenues, or prevent us from offering certain products and services. While we have adopted policies and procedures designed to ensure compliance with applicable laws and regulations, there can be no assurance that our employees, contractors or agents will not violate such laws and regulations. If we are found to have violated laws and regulations, it could materially adversely affect our reputation, financial condition and operating results. We also could be harmed by government investigations, litigation, or changes in laws and regulations directed at our customers, business partners, or suppliers in the technology industry that would have the effect of limiting our ability to do business with those entities. There can be no assurance that our business will not be materially adversely affected, individually or in the aggregate, by the outcomes of such investigations, litigation or changes to laws and regulations in the future.

Our business and the effectiveness of our platform depends on our ability to collect and use online data. New tools used by consumers to limit data collection, regulatory restrictions and potential changes to web browsers and mobile operating systems affect our ability to collect such data, which could harm our operating results and financial condition.

We have one of the largest compilations of personal data relating to U.S. and international consumers in the world. The ability of our platform to deliver high quality solutions to our customers is based on our technology’s capability to derive relevant, actionable insights from the data that we ingest into our systems and our ability to execute marketing programs across digital channels such as email, social media, website and other touchpoints to engage consumers. The principal way that we collect individual opted-in data is directly from the consumers when they register or interact with our platform (such as the DISQUS commenting system), or with partners’ services. We also use various tracking technologies, both proprietary and those provided through third-party suppliers in order to connect to individuals across marketing channels for the purpose of targeting consumers and delivering campaigns. The future of these and other digital data collection practices is evolving, with some prominent companies in the industry recently announcing that they will implement their own individual data collection tools and phase out others. This approach may or may not be compatible with our current operations in those channels and platforms. It is yet to be determined if there will be an industry-wide framework for targeting consumers in a digital environment. Furthermore, regulatory and legislative actions may influence which data collection tools are permitted in various jurisdictions and may further restrict our data collection efforts. Without this incremental data, we may not have sufficient insight into the consumer’s activity to provide some of our current tools, which may impact our capacity to execute our customers’ programs efficiently and effectively.

Consumers can, with increasing ease, implement technologies that limit our ability to collect and use data to track and deliver our solutions across different marketing channels and platforms. Various digital tracking tools may be deleted or blocked by consumers. The most commonly used internet browsers also allow consumers to modify their browser settings to block first-party cookies (placed directly by the publisher or website owner that the consumer intends to interact with), which are not affected by changes from web browsers and operating systems, or third-party cookies (placed by parties that do not have direct relationship with the consumer), which some browsers may block by default. Mobile devices using Android and iOS operating systems limit the ability of cookies, or similar technology, to track consumers while they are using applications other than their web browser on the device. Even if cookies and ad blockers do not ultimately have an adverse effect on our business, investor concerns about the utility and robustness of these tracking technologies could limit demand for our stock and cause its price to decline.

We also partner with third-party data suppliers and publishers. When we purchase or license from third-party data suppliers, we are dependent upon our ability to obtain such data on commercially reasonable terms and in compliance with applicable regulations. If a substantial number of data suppliers were to withdraw or withhold their data from us, or if we had to terminate our ties with data suppliers either due to commercial or regulatory reasons, our ability to provide products to our customers could be materially adversely impacted, which could result in decreased revenues and operating results. We cannot provide assurance that we will be successful in maintaining our relationships with these external data source providers or that we will be able to continue to obtain data from them on acceptable terms or at all. Furthermore, we cannot provide assurance that we will be able to obtain data from alternative sources if our current sources become unavailable.

Actual or perceived failures to comply with applicable data protection, privacy and security laws, regulations, standards and other requirements could adversely affect our business, results of operations, and financial condition.

The global data protection landscape is rapidly evolving, and we are or may become subject to numerous state, federal and foreign laws, requirements and regulations governing the collection, use, disclosure, retention, and security of personal

information. Implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future, and we cannot yet determine the impact future laws, regulations, standards, or perception of their requirements may have on our business. This evolution may create uncertainty in our business, affect our ability to operate in certain jurisdictions or to collect, store, transfer use and share personal information, necessitate the acceptance of more onerous obligations in our contracts, result in liability or impose additional costs on us. The cost of compliance with these laws, regulations and standards is high and is likely to increase in the future. Any failure or perceived failure by us to comply with federal, state or foreign laws or regulations, our internal policies and procedures or our contracts governing our processing of personal information could result in negative publicity, government investigations and enforcement actions, claims by third parties and damage to our reputation, any of which could have a material adverse effect on our operations, financial performance and business.

In the U.S., numerous state laws impose standards relating to the privacy, security, transmission and breach reporting of personal information. Such laws and regulations are subject to interpretation by various courts and other governmental authorities, thus creating potentially complex compliance issues for us, our customers and our strategic partners. For example, the CCPA went into effect on January 1, 2020. The CCPA creates individual privacy rights for California consumers and imposes privacy and security obligations on entities handling personal information. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches suffered as a result of the business’s violation of the duty to implement and maintain reasonable security procedures and practices, and this may lead to breach litigation. Further, the CPRA, effective January 1, 2023, significantly amended the CCPA and imposes additional data protection obligations on covered businesses, including additional consumer rights processes, limitations on data uses, new audit requirements for higher risk data, and opt outs for certain uses of sensitive data. It also created a new California data protection agency authorized to issue substantive regulations, which could result in increased privacy and information security enforcement. Similar laws are now in effect and enforceable in Virginia, Colorado, Connecticut, and Utah, and will soon be enforceable in several other states as well. Additionally, state regulators may exercise greater scrutiny regarding the collection and processing of personal information for purposes of online advertising, marketing, and analytics. These laws and their requirements could have a material adverse effect on our financial performance, and any liability from failure to comply with the requirements of these laws could adversely affect our financial condition.

Furthermore, the Federal Trade Commission (“FTC”) and many state Attorneys General continue to enforce federal and state consumer protection laws against companies for online collection, use, dissemination and security practices that appear to be unfair or deceptive. The FTC sees failure to take appropriate steps to keep consumers’ personal information secure as constituting unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act. The FTC expects a company’s data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. The FTC has recently conducted enforcement actions against other companies that created new precedents that may require us to adjust our business practices, although these changes have not produced material costs or loss of revenue for us. Future FTC enforcement actions against marketing companies could result in more material impacts to us. The FTC also has initiated a rulemaking regarding “Commercial Surveillance and Data Security,” and although that rule is not expected to come into effect soon, it has resulted in increased regulatory attention and scrutiny regarding the collection and processing of personal information and online advertising, marketing and analytics services.

Our communications with consumers are also subject to certain laws and regulations, including the Controlling the Assault of Non-Solicited Pornography and Marketing (“CAN-SPAM”) Act of 2003, the Telephone Consumer Protection Act of 1991 (the “TCPA”), and the Telemarketing Sales Rule and analogous state laws, that could expose us to significant damages awards, fines and other penalties that could materially impact our business. For example, the TCPA imposes various consumer consent requirements and other restrictions in connection with certain telemarketing activity and other communication with consumers by phone, fax or text message. Recently enacted state laws, for example in Connecticut and Maryland, create additional requirements and penalties for violations relating to telemarketing and SMS marketing. Numerous class-action suits under federal and state laws have been filed in recent years against companies who conduct telemarketing and/or SMS texting programs, with many resulting in multi-million-dollar settlements to the plaintiffs. Any future such litigation against us could be costly and time-consuming to defend. In particular, the TCPA and related state laws impose significant restrictions on the ability to make telephone calls or send text messages to mobile telephone numbers without the prior consent of the person being contacted. The CAN-SPAM Act and the Telemarketing Sales Rule and analogous state laws also impose various restrictions on marketing conducted using email, telephone, fax or text message. Additional laws, regulations, and standards covering marketing, advertising, and other activities conducted by telephone, email, mobile devices, and the internet may be or become applicable to our business, such as the Communications Act, the Federal Wiretap Act, the Electronic Communications Privacy Act, and similar state consumer protection and communication privacy laws, such as California’s Invasion of Privacy Act. As laws and regulations, including FTC enforcement, rapidly evolve to govern the use of these communications and marketing platforms, the failure by us, our employees or third parties acting at our direction to abide by applicable laws and regulations could adversely impact our business, financial condition and results of operations or subject us to fines or other penalties.

New requirements relating to automated, browser-based, or one-stop opt-out mechanisms (OOMs) such as the Global Privacy Control, the forthcoming opt-out mechanism for data brokers established under the California Delete Act, or other OOMs that will be established in the future may result in significantly larger numbers of consumers opting out of having their data used for marketing purposes versus historical averages. This could result in Zeta having less access to consumer data, impacting performance of our services or resulting in loss of business.

Our operations abroad may also be subject to increased scrutiny or attention from data protection authorities. For example, in Europe, we are subject to the European Union General Data Protection Regulation (the “EU GDPR”) and the United Kingdom’s General Data Protection Regulation and the Data Protection Act 2018 (the “UK GDPR”) (the EU GDPR and UK GDPR, together referred to as the “GDPR”), which impose strict requirements for processing the personal data of individuals within the EEA. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory enforcement of data protection requirements and potential fines for noncompliance. Since we are subject to the supervision of relevant data protection authorities under both the EU GDPR and the UK GDPR, we could be fined under each of these regimes independently, in respect of the same breach. Penalties for certain breaches are up to €20 million / £17.5 million or 4% of the annual global revenues of the noncompliant company, whichever is greater.

Among other requirements, the GDPR also regulates transfers of personal data subject to the GDPR to third countries that have not been found to provide adequate protection to such personal data, including the U.S.; in July 2020, the Court of Justice of the EU (“CJEU”) limited how organizations could lawfully transfer personal data from the EU/European Economic Area (“EEA”) to the U.S. by invalidating the Privacy Shield for purposes of international transfers and imposing further restrictions on the use of standard contractual clauses (“SCCs”) by stating reliance on SCCs alone may not be sufficient in all circumstances and that transfers must be assessed on a case-by-case basis. European court and regulatory decisions subsequent to the CJEU decision have taken a restrictive approach to international data transfers. Further the European Commission published revised standard contractual clauses for data transfers from the EEA (mandatory for new transfers since September 27, 2021, and for existing transfers since December 27, 2022) and the UK Information Commissioner’s Office published its own new data transfer standard contracts for data transfers from the UK (mandatory for new transfers since September 21, 2022 and for existing transfers by March 21, 2024). We expect the existing legal complexity and uncertainty regarding international data transfers to continue and in particular, we expect international transfers to the U.S. and other jurisdictions more generally to continue to be subject to enhanced scrutiny by regulators. As supervisory authorities issue further guidance on personal data export mechanisms, and/or start taking enforcement action, we could suffer additional costs, complaints and/or regulatory investigations or fines, and/or if we are otherwise unable to transfer personal data between and among countries and regions in which we operate, it could affect the manner in which we provide our services, the geographical location or segregation of our relevant systems and operations, and could adversely affect our financial results. In addition, in February 2022, the Belgian data protection authority found that the Interactive Advertising Bureau’s (IAB) “Transparency and Consent Framework” (“TCF”), the primary consent management platform used in Europe for online advertising compliance, violates the GDPR. While this decision is being appealed, a subsequent loss of the TCF could result in increased legal risk, or a need to discontinue online advertising in Europe, which could impact our revenues.

For transfers from the EEA to the UK the European Commission has adopted an adequacy decision in favor of the United Kingdom, enabling data transfers from EU member states to the United Kingdom without additional safeguards. However, the UK adequacy decision will automatically expire in June 2025 unless the European Commission re-assesses and renews or extends that decision.

We are also subject to evolving EU and UK privacy laws on cookies, tracking technologies and e-marketing. The GDPR also imposes conditions on obtaining valid consent for cookies, such as a prohibition on pre-checked consents and a requirement to ensure separate consents are sought for each type of cookie or similar technology. Recent European court and regulator decisions are driving increased attention to cookies and tracking technologies. In light of the complex and evolving nature of EU, EU Member State and UK privacy laws on cookies and tracking technologies, there can be no assurances that we will be successful in our efforts to comply with such laws and violations of such laws could result in regulatory investigations, fines, orders to cease / change our use of such technologies, as well as civil claims including class actions, and reputational damage. In July 2021, we received a notice from Norwegian authorities of an intent to impose a fine for our alleged failure to adhere to the GDPR with respect to the collection of personal data via cookies in their country. We have challenged this allegation on a number of grounds and currently await a response from the Norwegian DPA. We are hopeful that the Norwegian DPA will close this case without enforcement action as we have not received any correspondence since July 2022.

Increased scrutiny regarding the use of such technologies and the use of personal data for online advertising practices, together with adverse rulings on these issues, even if not directly against us, may have a direct impact on our ability to continue to collect and process personal data for the services that we provide and could adversely impact our business activities. Changes proposed by providers of major browsers to eliminate or restrict the usage of third-party cookies to track user behaviors, and to allow users to limit the collection of certain data generally or from specified websites, could impair our ability to collect user information,

including personal data and usage information, that helps us provide more targeted advertising to our current and prospective consumers. The effectiveness of our platform relies in part on our ability to collect and use online data, so these changes could adversely affect our business.

In Canada, the Personal Information Protection and Electronic Documents Act (“PIPEDA”), and various provincial laws require that companies give detailed privacy notices to consumers, obtain consent to use personal information, with limited exceptions, allow individuals to access and correct their personal information, and report certain data breaches. Failure to comply with PIPEDA or other Canadian provincial privacy or data protection laws could result in significant fines and penalties or possible damage awards.

Our data-driven platform may also be subject to laws and evolving regulations regarding the use of artificial intelligence and machine learning, controlling for data bias, and antidiscrimination. For example, in addition to enforcing Section 5 of the FTC Act, the FTC enforces the Fair Credit Reporting Act, and the Equal Credit Opportunity Act. These laws prohibit unfair and deceptive practices, including use of biased algorithms in artificial intelligence. The European Commission also recently published its proposal for a regulation implementing harmonized rules on artificial intelligence and amending certain union legislative acts. The proposed regulation would impose additional restrictions and obligations on providers of artificial intelligence systems, including increasing transparency so consumers know they are interacting with an artificial intelligence system, requiring human oversight in artificial intelligence, and prohibiting certain practices of artificial intelligence that could lead to physical or psychological harm. If federal or state regulators were to determine that the type of data we collect, the process we use for collecting this data or how we use it unfairly discriminates against some groups of people, laws and regulations could be interpreted or implemented to prohibit or restrict our collection or use of this data. Additionally, existing and future laws, and evolving attitudes about privacy protection may impair our ability to collect, use, and maintain data points of sufficient type or quantity to develop and train our artificial intelligence algorithms.

Although we work to comply with applicable laws, regulations and standards, our contractual obligations and other legal obligations, these requirements are evolving and may be modified, interpreted and applied in an inconsistent manner from one jurisdiction to another, and may conflict with one another or other legal obligations with which we must comply. Any failure or perceived failure by us or our employees, representatives, contractors, consultants, collaborators, or other third parties to comply with such requirements or adequately address privacy and security concerns, even if unfounded, could result in the imposition of significant civil and/or criminal penalties, damage in our reputation, private litigation, and restrictions on data processing.

Any unfavorable publicity or negative public perception of current data collection practices could result in additional regulations which may impact the effectiveness of our data cloud and platform.

The growth of the digital marketing industry has led to increased scrutiny from consumer groups, government agencies and news organizations. Any future negative publicity about the digital marketing industry as a whole or about an individual actor could result in government agencies playing a more active role in regulating and enforcing rules that relate to the collection, use, sharing and disclosure of data. For example, in recent years, consumer advocates, mainstream media and elected officials have increasingly and publicly criticized the digital marketing industry for its collection, storage and use of data.

As we process transactions through our platform, we collect large amounts of data about consumers and advertisements that we place. We collect data on ad specifications (such as placement, size and format), pricing and auction activity (such as price floors, bid response behavior and clearing prices). Further, we collect data on consumers that does not directly identify the individual (although considered personal information under the CCPA and other U.S. laws, GDPR, and other laws), including browser, device location and characteristics, online browsing behavior, exposure to and interaction with advertisements, and inferential data about purchase intentions and preferences. Data providers also send us proprietary data, including data about consumers. We aggregate this data and analyze it in order to enhance our product, including the pricing, placement and scheduling of advertisements. Evolving regulatory standards could place restrictions on the collection, management, aggregation and use of the types of data we collect, which could result in a material increase in the cost of collecting or otherwise obtaining certain kinds of data and could limit the ways in which we may use or disclose data. In addition, regulations such as the GDPR permit data protection authorities to impose penalties for violations. Any new and unforeseen regulatory limitations on our operations could impair our ability to deliver effective solutions to our customers, which could adversely affect our business, operating results and financial condition.

A significant inadvertent disclosure or breach of confidential and/or personal information we process, or a security breach of our or our customers’, suppliers’, or other partners’ IT Systems could be detrimental to our business, reputation, financial performance and results of operations.

The nature of our business means that we process large databases of personal information, including maintaining and storing large databases of such information, not only on our own behalf, but also on our customers’ and others’ behalf. As a result, we face numerous and evolving cybersecurity risks that threaten the confidentiality, integrity and availability of our IT Systems, and

personal and confidential information. Such risks include the misappropriation of data by malicious insiders or unauthorized third parties, or other data breaches. Such parties could attempt to gain entry to our or our vendor’s IT Systems (including by gaining employment at Zeta) for the purpose of stealing data, including confidential information or personal information, or breaching our security systems or other IT Systems. In particular, we (and certain of our third-party providers), like other organizations, especially in the digital marketing industry and marketing technology industry, are routinely subject to attempts by such threat actors (e.g., cybersecurity threats, attempted data privacy breaches, or other incidents), which if successful, may result in either threatened or actual exposure leading to unauthorized access, disclosure and misuse of confidential information, personal information or other information regarding customers, suppliers, partners, vendors, employees, or our company and business. Cyberattacks are expected to accelerate on a global basis in frequency and magnitude as threat actors are becoming increasingly sophisticated in using techniques and tools, including artificial intelligence, that circumvent security controls, evade detection and remove forensic evidence. As a result, we may be unable to detect, investigate, remediate or recover from future attacks or incidents, or to avoid a material adverse impact to our IT Systems or information.

Even where we have invested in industry standard security, a breach may be due to employee error, malfeasance, system errors or vulnerabilities, including vulnerabilities of our customers, vendors, suppliers, their products, or otherwise. Third parties may also attempt to fraudulently induce employees to disclose sensitive information or credentials that permit access to sensitive information through a process known as social engineering. This includes disclosing data such as usernames, passwords or other information to gain access to our customers’ data or our data, including intellectual property and other confidential information. Employee-related risks are increased by remote and hybrid working arrangements at our company (and at third-party providers) which increase cybersecurity risks due to the challenges associated with managing remote computing assets and security vulnerabilities that are present in many non-corporate and home networks. Third parties and threat actors also may attempt to extort us through a ransomware or other similar form of attack by encrypting information IT Systems, rendering our IT Systems inoperable, or stealing intellectual property, confidential information, personal information, or other sensitive data, and demanding payment in return. Techniques used to obtain unauthorized access to, or sabotage IT Systems, change frequently, grow more complex over time, and often are not recognized until launched against a target. Given the unpredictability of the timing, nature and scope of cybersecurity attacks and other security-related incidents, our technology may fail to adequately secure the data, including confidential information and personal information we maintain, and we cannot entirely eliminate the risk of improper or unauthorized access to or disclosure of such data, other security events that impact the integrity or availability of such data, or our IT Systems and operations and any data contained in such systems and operations. We may incur significant costs in protecting against or remediating such events, including cyber-attacks. Any security breach could result in operational disruptions that impair our ability to meet our customers’ requirements, which could result in decreased revenue. We carry insurance comparable to our industry. However, we cannot guarantee that our insurance coverage will be sufficient to cover all costs and liabilities incurred in relation to a security breach, or that applicable insurance will be available to us in the future on economically reasonable terms or at all.

Whether there is an actual or a perceived breach of our security, our reputation could suffer irreparable harm, causing our current and prospective customers to reject our products in the future, deterring data suppliers from supplying us data or customers from uploading their data on our platform, or changing customers’ behaviors and use of our technology. Further, we could be forced to expend significant resources in response to a security breach, including those expended in notifying individuals and providing mitigating solutions, repairing system damage, increasing cyber security protection costs by deploying additional personnel and protection technologies, and litigating and resolving legal claims or governmental inquiries and investigations, all of which could divert the attention of our management and key personnel away from our business operations.

We depend on third-party data centers, systems and technologies to operate our business, the disruption of which could adversely affect our business, operating results and financial condition.

In addition to internal technology, including proprietary software, databases, and other intellectual property, we also rely on computer hardware purchased or leased from, software licensed from, content licensed from and services provided by a variety of third parties, which include databases, operating systems, virtualization software, tax requirement content and geolocation content and services (collectively, “IT Systems”). Any damage to or failure of our IT Systems generally would prevent us from operating our business. We rely on data centers and third-party technology vendors in order to operate our business, and we host our company-owned infrastructure at third-party data centers. We are also dependent on third-party providers to provide industry standard protection against potential damages such as cyber intrusions, natural disasters, criminal acts and technical maintenance. In the event of damage or interruption to IT Systems, it is unlikely that we would be appropriately compensated for the reputational harm that such an interruption would create regardless of any damages we may recover from such third parties or any insurance policy in place. This would in turn reduce our revenue, subject us to liability and may cause us to lose customers, any of which could materially adversely affect our business.

Additionally, improving our platform’s infrastructure and expanding its capacity in anticipation of growth in new channels and formats, as well as implementing technological enhancements to our platform to improve its efficiency and

cost-effectiveness are key components of our business strategy, and if our third-party data centers are unable to keep up with our growing needs for capacity, this could have an adverse effect on our business. Any changes in the service levels at our third-party data centers or any errors, service interruptions, defects, disruptions, or other performance problems could adversely affect our reputation, expose us to liability, cause us to lose customers, or otherwise adversely affect our business, operating results and financial condition. Any errors, bugs or defects in such IT Systems could result in errors or a failure of our solutions, which could harm our business. Additionally, we cannot ensure that these third-party leases or licenses, or support for such leased or licensed products and technologies, will continue to be available to us on commercially reasonable terms, if at all. We cannot be certain that our suppliers or licensors are not infringing the intellectual property rights of others or that our suppliers and licensors have sufficient rights to the technology in all jurisdictions in which we may operate. In the future, we might need to license other hardware, software, content or services to enhance our products and meet evolving customer requirements. Any inability to license or otherwise obtain such hardware or software could result in a reduction in functionality, or errors or failures of our products, until equivalent technology is either developed by us or, if available, is identified, obtained through purchase or license, and integrated into our solutions, any of which may reduce demand for our solutions and increase our expenses. In addition, third-party licenses may expose us to increased risks, including risks associated with the integration of new technology, the diversion of resources from the development of our own proprietary technology, and our inability to generate revenue from new technology sufficient to offset associated acquisition and maintenance costs, all of which may increase our expenses and harm our results of operations.

If we fail to detect or prevent fraud or malware intrusion on our platform, devices, or systems, or into the systems or devices of our customers and their consumers, publishers could lose confidence in our platform, and we could face legal claims and regulatory investigations, any of which could adversely affect our business, operating results and financial condition.

We may be the target of fraudulent or malicious activities undertaken by persons seeking to use our platform for improper purposes. For example, someone may attempt to divert or artificially inflate customer purchases through our platform or attempt to disrupt or divert the operation of the systems and devices of our publishers and their consumers in order to misappropriate information, generate fraudulent billings or stage cyberattacks, or other unauthorized or illicit purposes. Those activities could also introduce malware through our platform in order to commandeer or gain access to confidential information or personal information. We use third-party tools and proprietary technology to identify non-human traffic and malware, and we may reduce or terminate relationships with customers that we find to be engaging in such activities. However, there can be no assurance that our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our systems and information. Perpetrators of fraudulent impressions and malware frequently change their tactics and may become more sophisticated over time, requiring both us and third parties to improve processes for assessing the quality of publisher inventory and controlling fraudulent activity. In the meantime, new or changing data privacy laws (in particular outside the EU and the U.S.) could potentially interfere with the data collection required in order to detect fraud. If we fail to detect or prevent fraudulent or malicious activity of this sort, our reputation could be damaged, customers may contest payment, demand refunds or fail to give us future business, or we could face legal claims or investigations from customers or regulators. Even if we are not directly involved in fraud or malicious activity, any sustained failures of others in our industry to adequately detect and prevent fraud could generate the perception that digital marketing is unsafe and lead our customers to avoid digital marketing products like ours.

The standards that private entities and inbox service providers adopt in the future to regulate the use and delivery of email may interfere with the effectiveness of our platform and our ability to conduct business.

Our business is dependent on email services for promoting our customers’ brands, products and services. Other private entities often advocate standards of conduct or practices that significantly exceed current legal requirements and classify certain solicitations that comply with current legal requirements as impermissible “spam.” Some of these entities maintain “blacklists” of companies and individuals, and the websites, inbox service providers and IP addresses associated with those entities or individuals that do not adhere to those standards of conduct or practices for commercial solicitations that the blacklisting entity believes are appropriate. If a company’s IP addresses are listed by a blacklisting entity, emails sent from those addresses may be blocked if they are sent to any internet domain or internet address that subscribes to the blacklisting entity’s service or uses its blacklist.

From time to time, some of our IP addresses have become, and we expect will continue to be, listed with one or more blacklisting entities due to the messaging practices of our customers and other users. We may be at an increased risk of having our IP addresses blacklisted due to our scale and volume of emails processed, compared to our smaller competitors. While the overall percentage of such email solicitations that our individual customers send may be at or below reasonable standards, the total aggregate number of all emails that we process on behalf of our customers may trigger increased scrutiny from these blacklisting entities. There can be no guarantee that we will be able to successfully remove ourselves from those lists. Because we fulfill email delivery on behalf of our customers, blacklisting of this type could undermine the effectiveness of our customers’ transactional email, email marketing programs and other email communications, all of which could have a material negative impact on our business, financial condition and results of operations.

Inbox service providers can also block emails from reaching their users. While we continually improve our own technology and work closely with inbox service providers to maintain our deliverability rates, the implementation of new or more restrictive policies by inbox service providers may make it more difficult to deliver our customers’ emails, particularly if we are not given adequate notice of a change in policy or struggle to update our platform to comply with the changed policy in a reasonable amount of time. In addition, some inbox service providers categorize as “promotional” emails that originate from email service providers and, as a result, direct them to an alternate or “tabbed” section of the recipient’s inbox. If inbox service providers materially limit or halt the delivery of our customers’ emails, or if we fail to deliver our customers’ emails in a manner compatible with inbox service providers’ email handling or authentication technologies or other policies, or if the open rates of our customers’ emails are negatively impacted by the actions of inbox service providers to categorize emails, then customers may question the effectiveness of our platform and cancel their accounts.

Additionally, changes in the laws or regulations that limit our ability to send such communications or impose additional requirements upon us in connection with sending such communications would also materially adversely impact our business. For example, Canada’s Anti-Spam Legislation (“CASL”) prohibits email marketing without the recipient’s consent, with limited exceptions. In addition, electronic marketing and privacy requirements in the EU are highly restrictive and differ greatly from those currently in force in the U.S., which could cause fewer individuals in the EU to subscribe to our marketing messages and drive up our costs and risk of regulatory oversight and fines if we are found to be non-compliant. These restrictions could prevent us from obtaining enough data to produce effective marketing results for our customers in these markets. Our use of email and other messaging services to send communications to consumers may also result in legal claims against us, for which we may incur increased expenses, and if successful might result in fines and orders with costly reporting and compliance obligations or might limit or prohibit our ability to send emails or other messages. We also rely on social networking messaging services to send communications and to encourage consumers to send communications. Changes to the terms of these social networking services to limit promotional communications, any restrictions that would limit our ability or our customers’ ability to send communications through their services, disruptions or downtime experienced by these social networking services or decline in the use of or engagement with social networking services by our customers’ end consumers could materially and adversely affect our business, financial condition and operating results.

Any actual or perceived failure to comply with evolving regulatory frameworks around the development and use of artificial intelligence could adversely affect our business, results of operations, and financial condition.

We leverage new technologies and platforms to improve business effectiveness, including use of artificial intelligence, or AI, technologies. The AI regulatory landscape is rapidly evolving, and we are or may become subject to numerous state, federal and foreign laws, requirements and regulations governing the use of AI. Implementation standards and enforcement practices are likely to remain uncertain for the foreseeable future, and we cannot yet determine the impact future laws, regulations, standards, or perception of their requirements may have on our business.

In the United States and internationally, AI is the subject of evolving review by various governmental and regulatory agencies, including the SEC and the FTC, and changes in laws, rules, directives and regulations governing the use of AI may adversely affect the ability of our business to use or rely on AI. For example, California and other states have implemented, or are in the process of implementing, laws, rules, and regulations that impose obligations on the use of automated decision making. Further, in October 2023, the President of the United States issued an executive order on the Safe, Secure and Trustworthy Development and Use of AI, emphasizing the need for transparency, accountability and fairness in the development and use of AI Tools.

In Europe, on December 8, 2023, the European Union legislators reached a political agreement on the EU Artificial Intelligence Act (“EU AI Act”), which establishes a comprehensive, risk-based governance framework for artificial intelligence in the EU market. The EU AI Act is expected to enter into force in 2024, and the majority of the substantive requirements will apply two years later. The EU AI Act will apply to companies that develop, use and/or provide artificial intelligence in the EU and includes requirements around transparency, conformity assessments and monitoring, risk assessments, human oversight, security, accuracy, general purpose artificial intelligence and foundation models, and proposes fines for breach of up to 7% of worldwide annual turnover. In addition, on September 28, 2022, the European Commission proposed two Directives seeking to establish a harmonized civil liability regime for artificial intelligence in the EU, in order to facilitate civil claims in respect of harm caused by artificial intelligence and to include artificial intelligence-enabled products within the scope of the EU’s existing strict liability regime. Once fully applicable, the EU AI Act will have a material impact on the way artificial intelligence is regulated in the EU, and together with developing guidance and/or decisions in this area, likely to affect our use of artificial intelligence and our ability to provide and to improve our services, require additional compliance measures and changes to our operations and processes, result in increased

compliance costs and potential increases in civil claims against us, and could adversely affect our business, operations and financial condition.

Failure to comply with industry self-regulation could adversely affect our business, operating results and financial condition.

In addition to complying with government regulations, we participate in trade associations and industry self-regulatory groups that promote best practices or codes of conduct addressing data privacy. We also have agreed to follow certain practices as contractual obligations to customers (e.g. marketing agencies). We are a member of the Digital Advertising Alliance’s (“DAA”) Self-Regulatory Principles for Online Behavioral Advertising in the U.S., as well as the Digital Advertising Alliance of Canada (“DAAC”) in Canada and the European Interactive Digital Advertising Alliance (“EDAA”) in Europe. Under the rules of these bodies, in addition to other compliance obligations, we are required to participate in the AdChoices program (and other similar programs), which provides consumers a single online interface to obtain information about and manage data collection by online third parties such as us. These bodies investigate non-compliance and report significant instances of non-compliance to regulatory authorities such as the FTC or data protection authorities in Europe. As new legislation comes into effect, self-regulatory programs may change their requirements based on such legislation, which adds complexity and costs for companies to maintain compliance. If we fail to keep up with or to properly implement such changes, we could become subject to regulatory investigations, fines and legally-mandated corrective actions.

Our intellectual property rights may be difficult to enforce and protect, which could enable others to copy or use aspects of our technology without compensating us, thereby eroding our competitive advantage and having an adverse effect on our business, operating results and financial condition.

Our success depends, in part, on our ability to protect the confidentiality of, and intellectual property rights in, our proprietary methods, technologies, and content that we develop or otherwise acquire, so that we can prevent others from using them. If we fail to protect such intellectual property rights adequately, or are otherwise required to disclose our proprietary methods, technologies and/or content, our competitors may gain access and our business might be adversely affected.

Policing unauthorized use of our technology is difficult and costly. In addition, the laws of some foreign countries may not be as protective of intellectual property rights as those of the U.S., and mechanisms for enforcement of our proprietary rights in such countries may be inadequate. If we are unable to protect our proprietary rights (including in particular, the proprietary aspects of our platform) we may find ourselves at a competitive disadvantage to others who have not incurred the same level of expense, time and effort to create, protect and enforce their intellectual property.

We rely upon a combination of trade secrets, third-party confidentiality and non-disclosure agreements, additional contractual protections including those in agreements with business partners and customers, and trademark, copyright, patent and other intellectual property laws to establish and protect our proprietary technology and intellectual property rights. Establishing, maintaining and enforcing intellectual property rights can be difficult, time consuming, and expensive and despite our efforts to establish and maintain our intellectual property, the applicable laws may provide only a limited scope of protection. It may be possible for unauthorized third parties to copy or reverse engineer aspects of our technology or otherwise obtain and use information that we regard as proprietary, or to develop technologies similar or superior to our technology or design around our proprietary rights, despite the steps we have taken to protect our proprietary rights. Our trade secrets, know-how and other proprietary information may be stolen, used in an unauthorized manner, or compromised through an intrusion by private parties or foreign actors into our computer systems. In addition, theft or misuse of our proprietary information could still occur by employees or contractors who have access to our technology despite the agreements we have in place with such employees and contractors that restrict the use and disclosure of our information and technology and although we enter into non-disclosure agreements with our customers, consultants, suppliers and other parties with whom we have strategic relationships and business alliances and enter into intellectual property assignment agreements with our consultants and suppliers, no assurance can be given that these agreements will not be breached.

While we have issued patents and have patent applications pending, we may be unable to obtain patent protection for the technology covered in our patent applications or such patent protection may not be obtained quickly enough to meet our business needs. Furthermore, the patent prosecution process is expensive, time-consuming and complex, and we may not be able to prepare, file, prosecute, maintain and enforce all necessary or desirable patent applications at a reasonable cost or in a timely manner. The scope of patent protection also can be reinterpreted after issuance and issued patents may be invalidated. Even if our patent applications do issue as patents, they may not issue in a form that is sufficiently broad to protect our technology, prevent competitors or other third parties from competing with us or otherwise provide us with any competitive advantage.

We may be subject to intellectual property rights claims by third parties, which are costly to defend, could require us to pay significant damages and could limit our ability to use our technology or intellectual property.

We operate in an industry with an extensive history of intellectual property litigation. There is a risk that our business, platform and solutions may infringe or be alleged to infringe the trademarks, copyrights, patents and other intellectual property rights of third parties, including patents held by our competitors or by non-practicing entities. We may also face allegations that our employees have misappropriated or divulged the trade secrets or other confidential information of their former employers or other third parties. Regardless of whether any of these claims have any merit, evaluating and defending these claims, including potentially challenging or attempting to invalidate the other party’s patents, is costly, time consuming, and diverts management attention and financial resources. Results of these litigation matters are difficult to predict and we may not be successful in defending ourselves in such matters. If our defense is unsuccessful, or we are not successful in challenging or invalidating the patents of the third party claiming infringement, we may be required to stop offering some features, purchase licenses, which may not be available on favorable terms or at all, or modify our technology or our platform while we develop non-infringing substitutes, or incur significant settlement costs. Additionally, we may be obligated to indemnify our customers or inventory and data suppliers in connection with any such litigation. Any of these events could have an adverse effect on our business, operating results and financial condition.

Our failure to meet content and inventory standards and provide products that our customers and third-party suppliers trust, could harm our brand and reputation and negatively impact our business, operating results and financial condition.

We do not provide or control either the content of the advertisements we serve or that of the websites providing the inventory. Our customers provide the content and third-party suppliers provide the inventory. Both marketers and third-party suppliers are concerned about being associated with content they consider inappropriate, competitive or inconsistent with their brands, or illegal and they are hesitant to spend money without guaranteed brand security. Additionally, our customers may seek to display marketing campaigns in jurisdictions that do not permit such campaigns. Our customers and third-party suppliers will often include provisions in their contracts that restrict the type of content that can be run in marketing campaigns. Inadvertently, we may serve such restricted ad content, or the advertisements we serve may contain malware, which could harm our or our customers’ brand and reputation, harm our relationships with our inventory suppliers and negatively impact our business, financial condition and operating results. Accordingly, a part of our business strategy is our ability to convince our customers that their brand and image are safe within our ecosystem. While we have established rules and guidance on how our platform is to be used, including prohibiting the display of content that is illegal, and we also utilize third party software that looks for malware in all of our marketing campaigns, we cannot guarantee that we will be able to capture all violating media before it is posted. It is therefore possible that our customers may run a campaign that does not conform to our standards. If this were to happen, we may be liable to the customer for damages and incur costs associated with remediating the issue. Further, if this were to happen it could harm our and/or our customers’ brand and reputation, and negatively impact our business, financial condition and operating results.

Additionally, marketing may result in litigation relating to copyright or trademark infringement, public performance royalties or other claims based on the nature and content of advertising that is distributed through our platform. Though we contractually require our customers to represent to us that they have the rights necessary to serve advertisements through our platform, we do not independently review or verify whether we are permitted to deliver, such advertisements. If any of our customers’ representations turn out to be inaccurate, we may be exposed to potential liability and our reputation may be damaged. While our customers are typically obligated to indemnify us, such indemnification may not fully cover us, or we may not be able to collect the amounts owed to us. In addition to settlement costs, we may be responsible for our own litigation costs, which can be extensive.

Our platform relies on third-party open source software components. Failure to comply with the terms of the underlying open source software licenses could expose us to liabilities, and the combination of open source software with code that we develop could compromise the proprietary nature of our platform.

Our platform utilizes software licensed to us by third-party authors under “open source” licenses and we expect to continue to utilize open source software in the future. The use of open source software may entail greater risks than the use of third-party commercial software, as open source licensors generally do not provide warranties or other contractual protections regarding infringement claims or the quality of the code. To the extent that our platform depends upon the successful operation of the open source software we use, any undetected errors or defects in this open source software could prevent the deployment or impair the functionality of our platform, delay new solution introductions, result in a failure of our platform and injure our reputation. For example, undetected errors or defects in open source software could render it vulnerable to breaches or security attacks, and, in conjunction, make our systems more vulnerable to data breaches.

Furthermore, some open source licenses require that proprietary source code combined with, linked to or distributed with such open source software be released to the public, and may also prohibit charging fees for the use of the software. If we

combine, link or distribute our proprietary software with open source software in a specific manner, we could, under some open source licenses, be required to release the source code of our proprietary software to the public. This could also preclude us from charging license fees. This would allow our competitors to create similar solutions with lower development effort and time and ultimately put us at a competitive disadvantage.

Risks Related to Our Indebtedness, Liquidity and Financial Position

Interest rate fluctuations may affect our results of operations and financial condition.

Because a substantial portion of our debt is variable-rate debt, fluctuations in interest rates could have a material effect on our business. We incur higher interest costs if interest rates increase. Interest rates were at historic lows during 2020 and 2021, when the United States Federal Reserve took several steps to protect the economy from the impact of the COVID-19 pandemic, including reducing interest rates to new historic lows. In 2022 and 2023, the United States Federal Reserve raised interest rates. Any such increase in interest costs could have a material adverse impact on our financial condition and the levels of cash we maintain for working capital.

We may need additional capital in the future to meet our financial obligations and to pursue our business objectives. Additional capital may not be available on favorable terms, or at all, which could compromise our ability to meet our financial obligations and grow our business.

We may need to raise additional capital to fund operations in the future or to finance acquisitions or other business objectives. Such additional capital may not be available on favorable terms or at all. Lack of sufficient capital resources could significantly limit our ability to meet our financial obligations or to take advantage of business and strategic opportunities. Any additional capital raised through the sale of equity or convertible debt securities would dilute stock ownership, and any new equity securities we issue could have rights, preferences and privileges superior to those of holders of our Class A common stock. Any debt financing we secure in the future could involve restrictive covenants relating to our capital raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, we may be required to delay, reduce the scope of, or eliminate material parts of our business strategy, including potential additional acquisitions or development of new technologies and geographic expansion.

Our loan agreement contains operating and financial covenants that may restrict our business and financing activities.

As of the date hereof, we have $185.0 million outstanding under our loan and security agreement (“Senior Secured Credit Facility”) with Bank of America, N.A., dated February 3, 2021. Borrowings under this agreement are secured by substantially all of our assets. For more information on our outstanding long-term borrowings, see Note 11 to our consolidated financial statements. This Senior Secured Credit Facility also restricts our ability, without the lender’s written consent, to, among other things:

• dispose of or sell our assets;

• make material changes in our business or management;

• consolidate or merge with other entities;

• incur additional indebtedness;

• create liens on our assets;

• pay dividends;

• make investments;

• enter into transactions with affiliates; and

• pay off or redeem subordinated indebtedness.

In addition, our Senior Secured Credit Facility contains customary minimum quarterly financial maintenance covenants.

The operating and financial restrictions and covenants in the Senior Secured Credit Facility, as well as any future financing arrangements that we may enter into, may restrict our ability to finance our operations, engage in, expand, or otherwise pursue our business activities and strategies. Our ability to comply with these or other covenants may be affected by events beyond our control, and future breaches of these or other covenants could result in a default under the Senior Secured Credit Facility. If not

waived, future defaults could cause all of the outstanding indebtedness under the Senior Secured Credit Facility to become immediately due and payable and our access to further credit under the Senior Secured Credit Facility may terminate. If we do not have or are unable to generate sufficient cash to repay our debt obligations when they become due and payable, either upon maturity or in the event of a default, we would be required to obtain additional debt or equity financing, which may not be available on favorable terms, or at all, which may negatively impact our ability to operate and continue our business as a going concern.

Risks Related to Certain Tax Matters

Our tax liabilities may be greater than anticipated.

The U.S. and non-U.S. tax laws applicable to our business activities are subject to interpretation and are changing. We are subject to audit by the Internal Revenue Service and by taxing authorities of the state, local and foreign jurisdictions in which we operate. Our tax obligations are based in part on our corporate operating structure, including the manner in which we develop, value, use and hold our intellectual property, the jurisdictions in which we operate, how tax authorities assess revenue-based taxes such as sales and use taxes, the scope of our international operations, and the value we ascribe to our intercompany transactions. Taxing authorities may challenge our tax positions and methodologies for valuing developed technology or intercompany arrangements, positions regarding the collection of sales and use taxes, and the jurisdictions in which we are subject to taxes, which could expose us to additional taxes. Any adverse outcomes of such challenges to our tax positions could result in additional taxes for prior periods, interest and penalties, as well as higher future taxes.

Additionally, our future effective tax rates could be adversely affected by changes in tax laws (including tax treaties) or their interpretation. For example, the Inflation Reduction Act, passed on August 16, 2022, included a 15 percent corporate minimum tax applicable to tax years beginning after December 31, 2022. We do not believe the corporate minimum tax will materially impact our effective tax rate or tax liability. Also, on October 8, 2021, the Organization for Economic Co-operation and Development ("OECD") released a statement on the OECD/G20 Inclusive Framework on Base Erosion and Profit Shifting, which agreed to a two-pillar solution to address tax challenges of the digital economy. On December 20, 2021, the OECD released Pillar Two model rules defining a 15 percent global minimum tax rate for large multinational corporations. The OECD continues to release additional guidance and countries are implementing legislation with widespread adoption of the Pillar Two Framework expected by calendar year 2024. Based on our current understanding of the minimum revenue thresholds contained in the proposed Pillar Two guidance, we are outside the scope of the implementation of the reporting requirements. However, we are continuing to evaluate the Pillar Two Framework and its potential impact on future periods.

We are currently unable to predict the ultimate impact of the Inflation Reduction Act and OECD requirements on our business, results of operations and financial condition. Moreover, the determination of our provision for income taxes and other tax liabilities requires significant estimates and judgment by management, and the tax treatment of certain transactions is uncertain. Any changes, ambiguity, or uncertainty in taxing jurisdictions’ administrative interpretations, decisions, policies and positions, including the position of taxing authorities with respect to revenue generated by reference to certain digital services, could also materially impact our income tax liabilities. Although we believe we will make reasonable estimates and judgments, the ultimate outcome of any particular issue may differ from the amounts previously recorded in our financial statements and any such occurrence could adversely affect our business, results of operations and financial condition.

Our ability to use our net operating loss carryforwards and certain other tax attributes may be limited.

We have incurred substantial net operating losses (“NOLs”) during our history. Under the rules of Sections 382 and 383 of the Internal Revenue Code of 1986, as amended (the “Code”), if a corporation undergoes an “ownership change,” generally defined as a greater than 50 percentage point change (by value) in its equity ownership over a rolling three-year period, the corporation’s ability to use its pre-change NOLs and other pre-change tax attributes to offset its post-change taxable income may be limited. We may experience ownership changes in the future as a result of future changes in our stock ownership, some of which changes may be outside our control. Similar provisions of state tax law may also apply to our state NOLs. As a result, if we earn net taxable income, our ability to use our pre-change NOL carryforwards to offset post-change taxable income may be subject to limitations. For these reasons, we may not be able to utilize a material portion of our NOLs and other tax attributes, which could adversely affect our future cash flows.

Risks Related to Public Reporting Matters and An Investment in Our Class A Common Stock

Substantial future sales of shares of our Class A common stock could cause the market price of our Class A common stock to decline and we may also expend substantial funds to satisfy a portion of our tax withholding and remittance obligations that arise upon the vesting and/or settlement of certain of our restricted stock awards, which may have an adverse effect on our financial condition and results of operations.

Sales of a substantial number of shares of our Class A common stock, particularly sales by our directors, executive officers and significant stockholders, or the perception that these sales might occur, could depress the market price of our Class A common stock. On June 10, 2022, the lock-up agreements that previously restricted certain holders of our capital stock from transferring or selling our shares expired. Additionally, our directors, executive officers, employees and, in certain instances, service providers, hold shares of common stock subject to outstanding options, time-based and performance-based restricted stock awards and restricted stock units under our equity incentive plans. Those shares and the shares reserved for future issuance under our equity incentive plans are and will become eligible for sale in the public market, subject to certain legal and contractual limitations. We cannot be certain whether and how many restricted stock units will satisfy their performance-based vesting conditions. Further, certain holders of our common stock have rights, subject to certain conditions, to require us to file registration statements covering their shares or to include their shares in registration statements that we may file for ourselves or our stockholders. We are unable to predict the effect that such sales related to the foregoing may have on the prevailing market price of our Class A common stock.

In addition, on August 3, 2022, the Company’s board of directors authorized withholding as an alternative to market sales by executives to satisfy tax withholding requirements upon vesting of restricted stock awards (“RSAs”). As such, beginning in the third quarter of 2022, we have used and may continue to use corporate cash to make required tax payments associated with the vesting of certain executive RSAs and withhold a corresponding number of shares from such executives. We anticipate that if we continue to utilize the withholding alternative, we will spend substantial funds to satisfy tax withholding and remittance obligations when we settle executive RSAs, which may have an adverse effect on our financial condition and results of operations.

We cannot guarantee that our share repurchase program will be fully consummated or that it will enhance long-term stockholder value. Share repurchases could also increase the volatility of the trading price of our common stock and could diminish our cash reserves.

In August 2022, our board of directors authorized a share repurchase program to repurchase shares of our outstanding Class A common stock through December 31, 2024. Although our board of directors has authorized this repurchase program, the program does not obligate us to repurchase any specific dollar amount or to acquire any specific number of shares. The actual timing and amount of repurchases remain subject to a variety of factors, including stock price, trading volume, market conditions and other general business considerations. In addition, the terms of our Senior Secured Credit Facility impose limitations on our ability to repurchase shares. The share repurchase program may be modified, suspended, or terminated at any time, and we cannot guarantee that the program will be fully consummated or that it will enhance long-term stockholder value. The program could affect the trading price of our stock and increase volatility, and any announcement of a termination of this program may result in a decrease in the trading price of our stock. In addition, this program could diminish our cash and cash equivalents and marketable securities.

The nature of our business requires the application of accounting guidance that requires management to make estimates and assumptions. Reported results under GAAP may vary from key metrics used to measure our business. Additionally, changes in accounting guidance may cause us to experience greater volatility in our quarterly and annual results.

We prepare our consolidated financial statements to conform to United States Generally Accepted Accounting Principles (“GAAP”). These accounting principles are subject to interpretation by the SEC, Financial Accounting Standards Board (“FASB”), and various bodies formed to interpret and create accounting rules and regulations. Accounting standards, such as ASC 606—Revenue from Contracts with Customers or ASC 842—Leases, or the guidance relating to interpretation and adoption of standards could have a significant effect on our financial results and could affect our business. Additionally, the FASB and the SEC are focused on the integrity of financial reporting, and our accounting policies are subject to scrutiny by regulators and the public.

We cannot predict the impact of future changes to accounting principles or our related accounting policies on our financial statements going forward. In addition, were we to change our accounting estimates, including those related to the timing of revenue recognition and those used to allocate revenue between various performance obligations, our reported revenue and results of operations could be significantly impacted. If we are unsuccessful in adapting to the requirements of any new standard, then we may experience greater volatility in our quarterly and annual results, which may cause our stock price to decline.

In addition, GAAP requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements. We base our estimates on historical experience and on various other assumptions that we believe to

be reasonable under the circumstances. Such estimates and assumptions are, by their nature, subject to substantial risks and uncertainties and factors may arise over time that lead us to change our methods, estimates, and judgments. Changes in those methods, estimates, and judgments could significantly affect our results of operations.

If we fail to maintain an effective system of disclosure controls and internal control over financial reporting, our ability to produce timely and accurate financial statements or comply with applicable regulations could be impaired.

Ensuring that we have adequate internal financial and accounting controls and procedures in place to produce accurate financial statements on a timely basis is a costly and time-consuming effort that needs to be re-evaluated frequently. The rapid growth of our operations in recent years and our initial public offering in 2021 have created a need for additional resources within the accounting and finance functions due to the increasing need to produce timely financial information and to ensure the level of segregation of duties customary for a U.S. public company. We continue to reassess the sufficiency of finance personnel in response to these increasing demands and expectations.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Our management does not expect that our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, within our company will have been detected.

We may experience material weaknesses in our internal controls over financial reporting in the future. Our failure to remediate these material weaknesses and maintain effective internal control over financial reporting could result in material misstatements in our financial statements, the inability to timely report our financial condition or results of operations, investors losing confidence in our reported financial information and our stock price being adversely affected.

We are a “controlled company” within the meaning of the NYSE rules and, as a result, expect to qualify for, and may rely on, exemptions from certain corporate governance requirements.

As of December 31, 2023, our Co-Founder and Chief Executive Officer, David Steinberg, beneficially owns a majority of the combined voting power of all classes of our outstanding voting stock. As a result, we continue to be a controlled company within the meaning of the applicable stock exchange corporate governance standards. Under the NYSE rules, a company of which more than 50% of the voting power is held by another person or group of persons acting together is a controlled company and may elect not to comply with certain corporate governance requirements, including the requirements that:

• a majority of the board of directors consist of independent directors as defined under the rules of the NYSE;

• the nominating and governance committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities; and

• the compensation committee be composed entirely of independent directors with a written charter addressing the committee’s purpose and responsibilities.

These requirements will not apply to us as long as we remain a controlled company. We have not elected to take advantage of the exemption from these requirements, but may elect to do so in the future so long as we remain a “controlled company.” If we choose to rely on these exemptions, you may not have the same protections afforded to stockholders of companies that are subject to all of the corporate governance requirements of the NYSE.

The dual class structure of our common stock has the effect of concentrating voting control with those stockholders who held our capital stock prior to the completion of our initial public offering, including our Co-Founder and Chief Executive Officer and his affiliates. This will limit or preclude your ability to influence corporate matters, including the election of directors, amendments to our organizational documents and any merger, consolidation, sale of all or substantially all of our assets, or other major corporate transaction requiring stockholder approval.

Our Class B common stock is entitled to ten votes per share and our Class A common stock is entitled to one vote per share. The dual class structure of our common stock has the effect of concentrating voting control with our Co-Founder and Chief Executive Officer and his affiliates, which will limit your ability to influence the outcome of matters submitted to our stockholders for approval, including the election of our directors and the approval of any change in control transaction.

As of December 31, 2023, our current founder and chief executive officer and his affiliates held, in aggregate 65.4% of the voting power of our outstanding capital stock. As a result, these stockholders, acting together, will have control over most matters that require approval by our stockholders, including the election of directors and approval of significant corporate transactions. They may also have interests that differ from yours and may vote in a way with which you disagree and which may be adverse to your interests. Corporate action might be taken even if other stockholders oppose them. This concentration of ownership may have the effect of delaying, preventing or deterring a change of control or other liquidity event of our company, could deprive our stockholders of an opportunity to receive a premium for their shares of common stock as part of a sale or other liquidity event and might ultimately affect the market price of our common stock.

Anti-takeover provisions contained in our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock.

Our amended and restated certificate of incorporation contains provisions that could delay or prevent a change in control of our company. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions do the following:

• permit our board of directors to issue up to 200,000,000 shares of preferred stock, with any rights, preferences and privileges as they may designate;

• provide that the authorized number of directors may be changed only by resolution of our board of directors;

• provide that our board of directors will be classified into three classes of directors;

• limit the ability of stockholders to remove directors to permit removals only “for cause” once Class B common stock ceases to hold more than 50% of all our outstanding common stock;

• provide that all vacancies, except as otherwise required by law, be filled by the affirmative vote of a majority of directors then in office, even if less than a quorum;

• prohibit stockholder action by written consent, subject to the terms of any series of preferred stock, if the holders of shares of Class B common stock no longer hold at least a majority of the voting power of the outstanding shares of our common stock;

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

• provide certain limitations on convening special stockholder meetings;

• so long as any shares of Class B common stock remain outstanding, require the prior affirmative vote of the holders of a majority of the outstanding shares of Class B common stock, voting as a separate class to consummate a Change of Control Transaction (as defined in our amended and restated certificate of incorporation);

• provide that the restrictions set forth in Section 203 of the Delaware General Corporation Law (“DGCL”) shall be applicable to us in the event that no holder of Class B common stock owns shares of our capital stock representing at least fifteen percent of the voting power of all the then outstanding shares of our capital stock; and

• not provide for cumulative voting rights in election of directors.

These and other provisions in our amended and restated certificate of incorporation and under Delaware law could discourage potential takeover attempts, reduce the price investors might be willing to pay in the future for shares of our Class A common stock and result in the market price of our Class A common stock being lower than it would be without these provisions.

Our amended and restated certificate of incorporation provides, subject to certain exceptions, that (i) the Court of Chancery of the State of Delaware is the sole and exclusive forum for certain stockholder litigation matters and (ii) the federal district courts of the United States of America are the exclusive forum for the resolution of any complaint asserting a cause of action 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 provides that the Court of Chancery of the State of Delaware is, to the fullest extent permitted by law, the sole and exclusive forum for:

• any derivative action or proceeding brought on our behalf;

• any action asserting a claim of breach of a fiduciary duty owed by, or other wrongdoing by, any of our current or former directors, officers, employees or our stockholders;

• any action asserting a claim against us arising under the DGCL, our amended and restated certificate of incorporation, or our amended and restated bylaws (as either may be amended from time to time) or as to which the DGCL confers jurisdiction on the Court of Chancery of the State of Delaware; and

• any action asserting a claim against us that is governed by the internal-affairs doctrine.

This exclusive forum provision may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, officers or other employees, which may discourage lawsuits against us and our directors, officers and other employees. Although our amended and restated certificate of incorporation contains the exclusive forum provision described above, it is possible that a court could find that such a provision is inapplicable for a particular claim or action or that such provision is unenforceable. If a court were to find the exclusive forum provision in our amended and restated certificate of incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving the dispute in other jurisdictions, which could seriously harm our business.

Under our amended and restated certificate of incorporation, the exclusive forum provision described above does not apply to claims arising under the Exchange Act. Accordingly, actions by our stockholders to enforce any duty or liability created by the Exchange Act or the rules and regulations thereunder must be brought in federal court. Our stockholders will not be deemed to have waived our compliance with the federal securities laws and the regulations promulgated thereunder.

We are a large accelerated filer and, subject to certain grace periods, may no longer provide scaled disclosures as an emerging growth company, which will increase our costs and demands on management.

As of December 31, 2023, we became a large accelerated filer, and are no longer an emerging growth company. As an emerging growth company, we had the option to take advantage of certain exemptions from various reporting requirements that are applicable to other public companies, including, but not limited to, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. Subject to certain grace periods, we may no longer provide scaled disclosure as an "emerging growth company" as defined under the Exchange Act, which will increase our costs and demands on management. In addition, as a non-accelerated filer and emerging growth company, we have availed ourselves of the exemption from the requirement that our independent registered public accounting firm attest to the effectiveness of our internal control over financial reporting under Section 404(b) of the Sarbanes Oxley Act. However, we may no longer avail ourselves of this exemption as a large accelerated filer, which will increase our expenses and require a significant amount of management time.

Item 1B. Unresolved Staff Comments.

None.

Item 1C. Cybersecurity.

Cybersecurity Risk Management and Strategy

We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information. Our cybersecurity risk management program includes a cybersecurity incident response plan.

We design and assess our program based on multiple cybersecurity frameworks, such as the National Institute of Standards and Technology Cybersecurity Framework (NIST CSF) and ISO 27001. This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use the NIST CSF, ISO 27001 and other frameworks as guides to help us identify, assess, and manage cybersecurity risks relevant to our business.

Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common methodologies, reporting channels and governance processes that apply across the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas.

Our cybersecurity risk management program includes:

We have not identified risks from known cybersecurity threats, including as a result of any prior cybersecurity incidents, that have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition, however, there can be no assurance that our cybersecurity risk management program and processes, including our policies, controls or procedures, will be fully implemented, complied with or effective in protecting our systems and information.

Cybersecurity Governance

Our Board considers cybersecurity risk as part of its risk oversight function and has delegated to the Audit Committee (Committee) the oversight of cybersecurity and other information technology risks. The Committee oversees management’s implementation of our cybersecurity risk management program.

The Committee receives regular reports from management on our cybersecurity risks. In addition, management updates the Committee, as necessary, regarding any material cybersecurity incidents, as well as any incidents with lesser impact potential.

The Committee reports to the full Board regarding its activities, including those related to cybersecurity. The full Board also receives briefings from management on our cyber risk management program. Board members receive presentations on cybersecurity topics from our Chief Information Officer (CIO), internal security staff or external experts as part of the Board’s continuing education on topics that impact public companies.

Our management team, including our CIO, Chief Information Security Office (CISO) and General Counsel, is responsible for assessing and managing our material risks from cybersecurity threats. The team has primary responsibility for our overall cybersecurity risk management program and supervises both our internal cybersecurity personnel and our retained external cybersecurity consultants. Our CIO (to whom the CISO reports) regularly attends meetings of the Committee. Our management team’s experience includes decades of experience working in information security, advanced education, and information security certifications.

Our management team supervises efforts to prevent, detect, mitigate, and remediate cybersecurity risks and incidents through various means, which may include briefings from internal security personnel; threat intelligence and other information obtained from governmental, public or private sources, including external consultants engaged by us; and alerts and reports produced by security tools deployed in the IT environment.

Item 2. Properties.

Our corporate headquarters is located in New York City, New York. It consists of approximately 23,000 square feet under a lease agreement that expires in March 2029. We have several offices in the U.S. and have operations in the UK, the EU and India, as well as other locations. Our New York office focuses on our go-to-market strategy, customer success, shared services and infrastructure. Our San Francisco and Silicon Valley offices serve as our innovation hubs. The European offices focus on go-to-market and customer success. The India offices concentrate on innovation, infrastructure and shared services.

All our offices are leased and we do not own any real property. We believe that our current facilities are sufficient to meet our present needs. As we grow, we expect that suitable additional space will be available to either expand existing offices or open new office locations.

Item 3. Legal Proceedings.

From time to time, we are involved in various legal proceedings arising from the normal course of business activities. We are not currently a party to any litigation the outcome of which, we believe, if determined adversely to us, would individually or

taken together have a material adverse effect on our business, operating results, cash flows, or financial condition. Defending any such proceedings is costly and can impose a significant burden on management and employees. The results of any current or future litigation cannot be predicted with certainty, and regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

We and members of our senior executive team have received subpoenas from the SEC in connection with an investigation into Kubient, Inc., a company we worked with prior to our initial public offering, and from the United States Attorney’s Office for the Southern District of New York, which is conducting a parallel investigation. The amount of business that we conducted with Kubient was quantitively insignificant to Zeta and we have not worked with Kubient since 2020. We are cooperating with the investigation.

For a description of our legal proceedings, see Note 8 to our audited consolidated financial statements in the “Financial Statements and Supplementary Data” section of this Annual Report on Form 10-K.

Overview

Zeta is a leading omnichannel data-driven cloud platform that provides enterprises with consumer intelligence and marketing automation software. We empower our customers to target, connect and engage consumers through software that delivers personalized marketing across all addressable channels, including email, social media, web, chat, Connected TV (“CTV”) and video, among others. We believe our actionable insights derived from consumer intent enable our customers to acquire, grow and retain consumer relationships more efficiently and effectively than the alternative solutions available in the market.

Our Zeta Marketing Platform, or ZMP, is the largest omnichannel marketing platform with identity data at its core. The ZMP can analyze billions of structured and unstructured data points to predict consumer intent by leveraging sophisticated machine learning algorithms and the industry’s largest opted-in data set for omnichannel marketing. The ZMP acts on these insights by connecting with consumers through native integration of marketing channels and application programming interface ("API") integration with third parties. The ZMP’s data-driven algorithms and processes learn and optimize each customer’s marketing program in real time, producing a ‘flywheel effect’ that enables our customers to test, learn and improve their marketing programs in real time.

The ZMP empowers our customers to personalize consumer experiences at scale across multiple touchpoints. Marketing programs are created and orchestrated by our customers through automated workflows and sophisticated dashboards. Our Consumer Data Platform ("CDP+") ingests, analyzes and distills disparate data points to generate a single view of a consumer, encompassing identity, profile characteristics, behaviors and purchase intent, which is then made accessible through a single console. Our Agile Intelligence suite synthesizes Zeta’s proprietary data and data generated by our customers to uncover consumer insights that are translated into marketing programs designed for highly targeted audiences across digital channels, including email, SMS, websites, applications, social media, CTV and chat.

Factors Affecting Results of Operations

The following factors have been important to our business and we expect them to impact our results of operations and financial condition in future periods:

New Scaled Customer Acquisition

We are focused on increasing the number of scaled customers that adopt the ZMP in their enterprises. We define “scaled customers” as customers from which we generated at least $100,000 in revenues in the trailing twelve months. Our long-term growth and operating results will depend on our ability to attract more scaled customers as we address their most pressing marketing automation needs. We will continue to focus on enterprises across multiple geographies. Between January 1, 2023 and December 31, 2023, our sales team increased by approximately 13 sales employees, and we expect to continue to invest in our go-to-market efforts in 2024. We have significantly enhanced our sales techniques in order to build a collaborative environment that encourages cross-selling and implemented a new learning and development program for our sales team. Our sales team productivity increases with tenure and our current management system gives us confidence that we are well positioned for sustainable growth. Our Agile Intelligence suite is a module that provides actionable insights to our customers and serves as an entry point into the ZMP. Agile Intelligence suite has been a proven way to land scaled customers, with minimal cost of implementation and high value adoption.

Drive Increase to Average Revenue Per User

During the year ended December 31, 2023, we experienced an increase in our scaled customer Average Revenue Per User (“ARPU”), which resulted in our revenues increasing for the year compared to the prior-year period. Our scaled customer ARPU growth resulted primarily from the initial effects of transitioning our sales team model to focus a dedicated team on new business development and a separate team on training and educating new and existing users on our platform capabilities. Our transition to this hunter/farmer sales model has included focusing more of our sales team on growth of existing scaled customers and aligning scaled customers with sellers that have specific industry expertise.

Expand Sales to Existing Customers

We adhere to a “land, expand, extend” sales model. After prospecting and landing new scaled customers, we focus on expanding sales to such scaled customers. This includes increasing their use of one product and/or embedding multiple products within an enterprise with our Agile Intelligence suite serving as the connective tissue across multiple products. We have scaled customers both in the U.S. and internationally and we believe we can achieve growth by cross-selling our existing solutions and introducing new features and functionalities within the platform. We expect that our ability to increase adoption of our products within existing scaled customers increases our future opportunities through additional sales. As part of this strategy, we expect to drive expansion in the number of channels per scaled customer. During the year ended December 31, 2023 and 2022, our channels per scaled customer were 2.1 and 2.0, respectively.

We use an annual net revenue retention (“NRR”) rate as a measure of our ability to retain and expand business generated from our existing customers base. We believe that many companies frequently use annual NRR rate as an indicator for determining customer loyalty. We calculate our annual NRR rate by dividing current year revenue earned from customers from which we also earned revenue in the prior year, by the prior year revenues. Our annual NRR rate was 110.9% and 111.5% for the years ended December 31, 2023 and 2022, respectively. We exclude political and advocacy customers, which represented 1.8% and 6.3% of revenue for 2023 and 2022, respectively, from our calculation of annual NRR rate because of the biennial nature of these customers.

Our customer loyalty is also reflected in the table below, which breaks down the tenure of our scaled customers for the year ended December 31, 2023.

Tenure for All Scaled Customers for Year Ended December 31, 2023

Additionally, of our 131 super-scaled customers who generate at least $1.0 million in revenue in the trailing twelve months, 87 have a tenure of 3+ years.

Adoption of Marketing Automation Products

Our ability to drive adoption of the ZMP will depend on the overall demand for marketing automation solutions. We expect continued strong investment in marketing technology by enterprise companies. Additionally, as enterprise marketing spend shifts towards digital from offline channels, we expect marketing automation technology will benefit. As a result, we expect our enterprise customer base to grow and propel greater platform deployment and usage. While we do not believe our competitors offer a comparable all-in-one platform solution for marketing automation, certain competitors offer point solutions that compete with specific tools and products we offer as part of the ZMP. Potential customers may also elect to build in-house solutions for marketing automation. While it is difficult to predict adoption rates and future product demand, we are focused on continuing to innovate and create marketing automation products that address the business requirements of our customers better than alternative solutions.

Investment in Innovation

We intend to invest in our business in order to drive long-term growth in an expanding market and capture economies of scale derived from a larger business base. For example, we plan to invest in our research and development activities to ensure we remain at the forefront of data management, AI development and marketing automation. We will also continue to invest in our sales and marketing capabilities. Lastly, we expect to invest in the expansion of markets including international and the B2B sector. We plan to incur additional general and administrative expenses to support our growth. Even as cost of revenues (excluding depreciation and amortization) and other expenses fluctuate over time and may be negatively impacted by factors beyond our control, we plan to remain focused on making necessary investments to drive long-term growth.

Seasonality

In general, the marketing industry experiences seasonal trends that affect the vast majority of participants in the digital marketing ecosystem. Historically, marketing activity is higher in the fourth quarter of the calendar year to coincide with the holiday shopping season as compared to the first quarter. As a result, the subsequent first quarter tends to reflect lower activity levels and lower performance. We generally expect these seasonality trends to continue and our ability to effectively manage our resources in anticipation of these trends may affect our operating results.

Key Performance Metrics

We review key performance metrics, discussed below, to evaluate our business, track performance, identify trends, formulate plans and make strategic decisions. We believe that the presentation of such metrics provides investors with effective ways to measure and model the performance of companies such as ours, with recurring revenue streams.

Scaled customers

We measure and track the number of scaled customers on a trailing twelve months basis because our ability to attract new scaled customers, grow our scaled customer base and retain or expand our business with existing scaled customers is both an important contributor to our revenue growth and an indicator to investors of our measurable success. We define scaled customers as customers from which we generated at least $100,000 in revenues during the trailing twelve months. As a subset of scaled customers, we define super-scaled customers as customers from which we generated at least $1.0 million in revenues during the trailing twelve months. We calculate the number of scaled and super-scaled customers at the end of each reporting period as the number of customers billed during each applicable period. In 2023, we had 452 scaled customers that representing 97% of total revenue, compared to 403 scaled customers representing 98% of total revenue in 2022.

Scaled customers increased 12% for the year ended December 31, 2023, as compared to 2022, primarily due to growth in our customer base in the U.S. Of our scaled customers, 131 and 103 are super-scaled customers for the years ended December 31, 2023 and December 31, 2022, respectively.

Scaled customer ARPU

We believe that our ability to increase scaled customer ARPU is an indicator of our ability to grow the long-term value of existing customer relationships. We calculate the scaled customer ARPU as revenue for the corresponding period divided by the number of scaled customers during that period. We believe that scaled customer ARPU is useful for investors because it is an indicator of our ability to increase revenue and scale our business.

Scaled customer ARPU increased 10% for the year ended December 31, 2023, as compared to 2022, primarily due to higher usage of our platform among scaled customers. ARPU for our super-scaled customers was $4.5 million, across 131 customers for the year ended December 31, 2023 and was $4.5 million, across 103 customers for the year ended December 31, 2022.

Description of Certain Components of Financial Data

Revenues

Our revenue primarily arises from use of our technology platform via subscription fees, volume-based utilization fees and fees for professional services. Our platform revenue comprised of a mix of direct platform revenue and integrated platform revenue, which leverages API integrations with third parties. For 2023 and 2022, we derived 72% and 77% of our revenues from direct platform revenue, respectively, and 28% and 23% of our revenues from integrated platform revenue, respectively. Revenues are recognized when control of these services is transferred to our customers, in an amount that reflects the consideration we expect to be entitled to in exchange for those services. Sales and other taxes collected by us are excluded from revenue. Our revenue recognition policies are discussed in more detail under “Critical Accounting Estimates.”

Cost of revenues (excluding depreciation and amortization)

Cost of revenue excludes depreciation and amortization and consists primarily of media and marketing costs and certain employee-related costs. Media and marketing costs consist primarily of fees paid to third-party publishers, media owners or managers, and strategic partners that are directly related to a revenue-generating events. We pay these third-party publishers, media owners or managers and strategic partners on a revenue-share, a cost-per-lead, cost-per-click, or cost-per-thousand-impressions basis. Expenses related to “internet traffic” associated with the viewing of available impressions or queries per second and costs of providing support to our customers are also included in the cost of revenues (excluding depreciation and amortization). Employee-related costs included in cost of revenues (excluding depreciation and amortization) include salaries, bonuses, commissions, stock-based compensation and employee benefit costs primarily related to individuals directly associated with providing services to our customers. Our cost of revenues (excluding depreciation and amortization) are dependent on the revenue mix and therefore can slightly increase or decrease in the future as a percentage of revenue over the long term.

General and administrative expenses

General and administrative expenses primarily consist of computer and telecom expenses, employee-related costs, including salaries, bonuses, stock-based compensation and employee benefits costs associated with our executives, finance, legal, human resources and other administrative personnel, as well as accounting and legal professional services fees and platform and related infrastructure costs. We expect general and administrative expenses to increase in absolute dollars in future periods. We expect that general and administrative expenses to decrease as a percentage of revenue over the long term.

Selling and marketing expenses

Selling and marketing expenses primarily consist of employee-related costs, including salaries, bonuses, employee benefits costs, stock-based compensation and commission costs for our sales and marketing personnel. Selling and marketing expenses also include costs for market development programs, advertising, promotional and other marketing activities. We intend to continue to invest in marketing initiatives and as a result we expect selling and marketing expenses to increase in absolute dollars in future periods. Selling and marketing expenses as a percentage of revenue may fluctuate from period to period based on revenue levels and the timing of our investments in these functions over the long term.

Research and development expenses

Research and development expenses primarily consists of employee-related costs, including salaries, bonuses and employee benefit costs, stock-based compensation associated with engineering and IT services associated with the ongoing research and maintenance of internal use software. We expect to continue to invest in research and development in order to develop our technology platform to drive incremental value and growth and as a result we expect that research and development expenses may fluctuate from period to period as a percentage of revenue over the long term.

Depreciation and amortization

Depreciation and amortization relate to property and equipment, website and software development costs as well as acquisition-related and other acquired intangible assets. We record depreciation and amortization using straight-line method over the estimated useful life of the assets.

Acquisition-related expenses

Acquisition-related expenses primarily consists of legal fees associated with certain business combinations. We expect that acquisition-related expenses will be correlated with future acquisitions (if any), which could be greater than or less than our historic levels.

Restructuring expenses

Restructuring expenses consists primarily of employee termination costs due to internal restructuring. We expect that restructuring expenses will be correlated with future restructuring activities (if any), which could be greater than or less than our historic levels.

Interest expense

Interest expense primarily consists of interest payable on our long-term borrowings, net of interest earned on our short term investments in money market accounts and other short term deposits. We anticipate interest expense to be impacted by changes in variable interest rates.

Other expenses / (income)

Other expenses / (income) primarily consist of changes in fair value of acquisition-related liabilities, gains and losses on sale of assets and foreign exchange gains and losses. We expect that the magnitude of other income and expenses will depend on external factors such as foreign exchange rate and the remeasurement impact of acquisition related liabilities, which depends on the performance of our acquisitions and could be greater than or less than our historic levels.

Change in fair value of warrants and derivative liabilities

Change in fair value of warrants and derivative liabilities primarily relates to warrants to purchase shares of our common stock that we issued in connection with previous financing rounds, these warrants were converted into our Class A Common Stock upon IPO and as such there is no revaluation impact of warrant liabilities during the year ended on December 31, 2023. Historically, our derivative liability represented the conversion feature on our redeemable convertible preferred stock, which also extinguished upon our IPO. When we enter into transactions that include certain features that qualify to be embedded derivatives in accordance with ASC Topic 815, that requires to bifurcate such features from their host instruments and account for them as free-standing derivative financial instruments if certain criteria are met. Future changes in the fair value of warrants and derivative liabilities depends on the Company entering into transactions that contain warrants or derivative features.

Income tax provision / (benefit)

We account for income taxes in accordance with ASC 740, Income Taxes, which requires an asset and liability approach for the financial accounting and reporting of income taxes. Under this method, deferred tax assets and liabilities are determined based on temporary differences between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax laws is recognized in the consolidated statements of operations in the period that includes the enactment date. A valuation allowance is established when we determine that it is more likely than not that some portion or all of the deferred tax assets will not be realized. We have concluded that the U.S. deferred tax assets are not realizable on a more-likely-than-not basis and that a full valuation allowance is required.

Stock-based compensation

The measurement of stock-based compensation for all stock-based payment awards, including restricted stock, performance stock units (“PSUs”) and stock options granted to employees, consultants or advisors and non-employee directors, and shares purchased under the Company’s employee stock purchase plan (“ESPP”), is based on the estimated fair value of the awards on the date of grant or date of modification of such grants. See Note 13 to our consolidated financial statements for further details.

We estimate the recognition of unrecognized stock-based compensation (in thousands) as follows, subject to future forfeitures:

Results of Operations

We operate as a single reportable segment to reflect the way our Chief Operating Decision Maker (“CODM”) reviews and assesses the performance of the business. Our CODM is the Chief Executive Officer.

Comparison of the Years Ended December 31, 2023 and 2022

Revenues

Revenues increased by $137.8 million, or 23.3%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. The increase in revenues is attributable to incremental revenues of $35.6 million from existing customers and $102.2 million from new customers (including approximately $5.5 million from the acquisitions made during the year ended December 31, 2023).

Cost of revenues (excluding depreciation and amortization)

Cost of revenues (excluding depreciation and amortization) increased by $59.0 million, or 27.4%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. This increase was primarily driven by $61.2 million in incremental media costs and employee related costs of $1.9 million. This increase was partially offset by lower stock-based compensation of $4.1 million.

General and administrative expenses

General and administrative expenses decreased by $8.2 million, or 3.8%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. This decrease was primarily driven by lower stock-based compensation of $24.9 million, which was partially offset by higher professional services fees of $5.3 million, computer and telecom related expenses of $8.8 million, employee related costs of $0.9 million and an incremental provision for doubtful debt of $1.6 million.

Selling and marketing expenses

Selling and marketing expenses decreased by $10.8 million, or 3.6%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. This decrease was primarily driven by lower stock-based compensation of $27.6 million and other sales and marketing-related expenses of $0.6 million, which was partially offset by higher employee-related costs of $17.4 million.

Research and development expenses

Research and development expenses increased by $4.4 million, or 6.4%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. This increase was primarily driven by an increase in employee related costs of $3.0 million, consulting fees of $0.8 million and stock-based compensation of $0.6 million.

Depreciation and amortization

Depreciation and amortization expense decreased by $0.7 million, or 1.4%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. This decrease was driven by lower amortization expense of $0.7 million related to intangible assets.

Acquisition-related expenses

Acquisition-related expenses decreased by $0.1 million, or 41%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022, primarily driven by lower legal and professional fees incurred for our business combinations.

Restructuring expenses

We recorded restructuring expenses of $2.8 million during the year ended December 31, 2023 related to employee termination costs due to internal restructuring. We did not have any such restructuring expenses for the year ended December 31, 2022.

Interest expense

Interest expense increased by $3.6 million, or 49.8%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022 primarily as a result of increases in interest rates in recent periods. This increase was partially offset by higher income earned on our money market accounts and short term deposits.

Other expenses

Other expenses decreased by $6.2 million, or 44.1%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. This decrease was primarily driven by lower changes in fair value of acquisition-related liabilities recorded during the year ended December 31, 2023 as compared to the year ended December 31, 2022.

Change in fair value of warrants and derivative liabilities

We did not record any change in fair value of warrants and derivative liabilities during the year ended December 31, 2023. The change in fair value of warrants and derivative liabilities during the year ended December 31, 2022 was primarily due to the change in fair value of certain derivative instruments issued by the Company.

Income tax Provision / (benefit)

Income tax provision increased by $2.5 million, or 169.6%, for the year ended December 31, 2023 as compared to the year ended December 31, 2022. For the year ended December 31, 2023, we recorded an income tax provision of $1,037, which primarily relates to an income tax provision for foreign taxes. For the year ended December 31, 2022, we recorded an income tax benefit of $1,491, which primarily related to the partial release of our U.S. valuation allowance as a business combination consummated during 2022, which created a source of future taxable income, partially offset by an income tax provision for foreign taxes.

The effective tax rates for the years ended December 31, 2023 was negative 0.5% and for the years ended December 31, 2022 was 0.5%. For both 2023 and 2022, our effective tax rates differ from the U.S. federal statutory rate of 21% primarily related to changes in our U.S valuation allowance as we maintain a full valuation allowance against our U.S. net deferred tax assets based upon the weight of objective evidence.

Non-GAAP Financial Measures

We use the following non-GAAP financial information, collectively, to evaluate our ongoing operations and for internal planning and forecasting purposes. Non-GAAP financial information is presented for supplemental informational purposes only, should not be considered a substitute for financial information presented in accordance with generally accepted accounting principles, and may be different from similarly titled non-GAAP measures used by other companies. Whenever we use a non-GAAP financial measure, a reconciliation is provided to the most closely applicable financial measure stated in accordance with generally accepted accounting principles. We believe that these non-GAAP financial measures may be useful to investors in analyzing our financial and operational performance.

Adjusted EBITDA and adjusted EBITDA margin

Adjusted EBITDA is a non-GAAP financial measure defined as net loss adjusted for interest expense, depreciation and amortization, stock-based compensation, income tax (benefit) / provision, acquisition-related expenses, restructuring expenses, change in fair value of warrants and derivative liabilities, certain dispute settlement expenses, gain on extinguishment of debt, certain non-recurring IPO related expenses, including the payroll taxes related to vesting of restricted stock and restricted stock units upon the completion of our IPO, and other (income) / expenses. Acquisition-related expenses primarily consist of legal fees associated with certain business combinations and restructuring expenses are severance and other employee-related costs which we do not expect to incur in the future, which may distort the comparability of the results of operations. Change in fair value of warrants and derivative liabilities is a non-cash expense related to periodically recording “mark-to-market” changes in the valuation of derivatives and warrants. Other (income) / expenses consists of non-cash expenses such as changes in fair value of acquisition-related liabilities, gains and losses on sales of assets and foreign exchange gains and losses. In particular, we believe that the exclusion of stock-based compensation, certain dispute settlement expenses and non-recurring IPO related expenses that are not related to our core operations provides measures for period-to-period comparisons of our business and provides additional insight into our core controllable costs. Adjusted EBITDA margin is a non-GAAP metric defined as adjusted EBITDA divided by the total revenues for the same period. Adjusted EBITDA and adjusted EBITDA margin provide us with a useful measure for period-to-period comparisons of our business as well as comparison to our peers. Our use of adjusted EBITDA and adjusted EBITDA margin has limitations as an analytical tool, and you should not consider these measures in isolation or as a substitute for analysis of our financial results as reported under GAAP. Because of these and other limitations, you should consider our non-GAAP measures only as supplemental to other GAAP-based financial performance measures, including revenues and net loss.

The following table reconciles adjusted EBITDA and adjusted EBITDA margin to net loss and net loss margin, the most directly comparable financial measure calculated and presented in accordance with GAAP.

Liquidity and Capital Resources

We have financed our operations and capital expenditures primarily through utilization of cash generated from operations, as well as borrowings under our credit facilities. As of December 31, 2023, we had cash and cash equivalents of $131.7 million and net working capital, consisting of current assets less current liabilities, of $133.4 million. As of December 31, 2023, we had an accumulated deficit of $958.5 million.

We believe our existing cash and anticipated net cash provided by operating activities, together with available borrowings under our credit facility, will be sufficient to meet our working capital requirements for at least the next 12 months and thereafter for the foreseeable future. However, if our operating performance during the next 12 months is below our expectations, our liquidity and ability to operate our business could be adversely affected. Our future capital requirements and the adequacy of available funds will depend on many factors, including those set forth under “Risk Factors.” In the future, we may attempt to raise additional capital through sales of equity securities or through equity linked or debt financing arrangements. Any future indebtedness we incur may result in terms that could be unfavorable to our equity investors. We cannot guarantee that we will be able to raise additional capital in the future on favorable terms, or at all. Any inability to raise capital could adversely affect our ability to achieve our business objectives.

Cash flows

The following table summarizes our cash flows for the periods presented:

Net cash provided by operating activities

During the year ended December 31, 2023, net cash provided by operating activities of $90.5 million resulted primarily from adjusted non-cash items of $303.3 million, more than offsetting our net loss of $187.5 million. Non-cash items include stock-based compensation of $242.9 million, depreciation and amortization of $51.1 million and a change in fair value of acquisition related liabilities of $7.2 million. Changes in working capital were primarily driven by increases in accounts receivable of $64.1 million and other assets of $1.3 million, partially offset by increases in accounts payable of $26.3 million and accrued expenses and other current liabilities of $12.0 million and a decrease in prepaid expenses of $1.1 million.

During the year ended December 31, 2022, net cash provided by operating activities of $78.5 million resulted primarily from adjusted non-cash items of $361.0 million, more than offsetting our net loss of $279.2 million. Non-cash items include stock-based compensation of $299.0 million, depreciation and amortization of $51.9 million, and a change in fair value of acquisition related liabilities of $13.0 million. Changes in working capital were primarily driven by an increase in accounts receivable of $19.8 million and a decrease in deferred revenue of $4.6 million, partially offset by increases in accounts payable of $13.5 million and accrued expenses and other current liabilities of $8.0 million.

Net cash used in investing activities

During the year ended December 31, 2023, we used $54.2 million of cash in investing activities, primarily consisting of capital expenditures of $20.5 million (including a $16.2 million investment in data and partnership agreements), website and software development costs of $15.5 million and business and asset acquisitions and other investments of $18.2 million (net of cash acquired).

During the year ended December 31, 2022, we used $48.4 million of cash in investing activities, primarily consisting of capital expenditures of $22.2 million (including a $18.6 million investment in data and partnership agreements), website and software development costs of $17.0 million and business and asset acquisitions and other investments of $9.2 million (net of cash acquired).

Net cash provided by financing activities

During the year ended December 31, 2023, we used $25.7 million of cash in financing activities, primarily due to the repurchase of $13.4 million of common stock repurchased under our repurchase and RSA withholdings program and payment of acquisition related liabilities of $15.5 million, partially offset by $3.1 million paid by certain employees under the Company's employee stock purchase plan.

During the year ended December 31, 2022, we used $12.6 million of cash in financing activities, primarily due to the repurchase of $9.6 million of common stock repurchased under our repurchase and RSA withholdings program and payment of

acquisition related liabilities of $6.0 million, partially offset by $2.7 million paid by certain employees under the Company's employee stock purchase plan.

Debt

As of December 31, 2023, we have $184.1 million (net of $0.9 million of unamortized debt acquisition costs) of outstanding long-term borrowings.

On February 3, 2021, we entered into a $222.5 million Senior Secured Credit Facility which was used to fully repay and terminate our previous credit agreement. On March 22, 2023, we entered into a $25.0 million incremental revolving facility commitment (the “2023 Incremental Revolving Commitment”) pursuant to an amendment to the Senior Secured Credit Facility, thereby increasing our total credit facility to $247.5 million. Borrowings under the debt were $185.0 million and bear interest payable quarterly ranging from SOFR plus 2.125% to SOFR plus 2.625% based on our consolidated net leverage ratio stated in the credit agreement. We are required to repay the principal balance and any unpaid accrued interest on the Senior Secured Credit Facility on February 3, 2026.

We are currently in compliance with our financial maintenance covenants under the Senior Secured Credit Facility and, based upon our current expectations, believe that we will continue to comply with our financial maintenance covenants for the next 12 months. The Senior Secured Credit Facility contains restrictive covenants that place restrictions on us and may limit our ability to, among other things, incur additional debt and liens, purchase our securities, undertake transactions with affiliates, make other investments, pay dividends or distribute excess cash flow.

During the year ended December 31, 2023, we borrowed $11.3 million against the revolver facility and repaid the same amount against the term loan under the credit facility.

We do not engage in off-balance sheet financing arrangements.

Contractual obligations

As of December 31, 2023, our material contractual obligations were as follows:

Acquisition-related contingent consideration payables and holdback payables are contractual obligations for which the timing of cash out flow cannot be estimated. Contingent consideration estimates may change based on actual results and may differ from management’s current expectations. For more information refer to Note 7 and Note 8 to our consolidated financial statements and notes thereto included in the “Financial Statements and Supplementary Data” section of this Annual Report on Form 10-K.

Share Repurchase and RSA Withholding Program

In August 2022, the Company's Board of Directors authorized a share repurchase and withholding program (the “2022 SRP”) authorizing the repurchase of up to $50.0 million of our outstanding Class A common stock through December 31, 2024 and authorizing withholding as an alternative to market sales by executives to satisfy tax withholding requirements upon vesting of restricted stock awards (“RSAs”). As such, we may use corporate cash to make required tax payments associated with the vesting of certain executive RSAs and withhold a corresponding number of shares from such executives. The actual timing, number and value of shares repurchased will be determined by the Company at its discretion and will depend on a number of factors, including market conditions, applicable legal requirements, our capital needs, and whether there is a better alternative use of capital. Repurchases and withholdings during any given fiscal period under the 2022 SRP will reduce the number of weighted-average common shares outstanding for the period. See Item 5 “Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities—Purchases of Equity Securities by the Issuer or Affiliated Purchaser” for more information on the 2022 SRP.
