“may,” “potential,” “should,” “will,” “would,” variations of such words and similar expressions are also intended to identify such forward-looking

different from those expressed in these forward-looking statements. Except as required by law, we undertake no obligation to revise or

decision to enter into an acquisition and/or fund investments in our latest technology arising from rapid market adoption that

could require us to seek additional equity or debt financing;

•our expectations relating to the amount and timing of recognized revenue from our projects;

•our expectations relating to expenses;

•our expectation that we will continue to receive a tax benefit related to U.S. federal foreign-derived intangible income and

Note 1 — Description of Business and Significant Accounting Policies

Energy Recovery, Inc. and its wholly-owned subsidiaries (the “Company” or “Energy Recovery”) designs and manufactures reliable,

high-performance solutions that provide cost savings through improved energy efficiency in commercial and industrial processes, with

applications across several industries. Leveraging the Company’s pressure exchanger technology, which generates little to no emissions

when operating, the Company believes its solutions lower costs, save energy, reduce waste, and minimize emissions for companies across a

variety of commercial and industrial processes. As the world coalesces around the urgent need to address climate change and its impacts,

the Company is helping companies reduce their energy consumption in their industrial processes, which in turn, reduces their carbon

footprint. The Company believes that its customers do not have to sacrifice quality and cost savings for sustainability and the Company is

committed to developing solutions that drive long-term value – both financial and environmental. The Company’s solutions are marketed,

sold in, and developed for, the fluid-flow and gas markets, such as seawater and wastewater desalination, natural gas, chemical processing

and CO2-based refrigeration systems, under the trademarks ERI®, PX®, Pressure Exchanger®, PX® Pressure Exchanger® (“PX”), Ultra PX™,

PX G™, PX G1300™, PX PowerTrain™, AT™, and Aquabold™. The Company owns, manufactures and/or develops its solutions, in whole or in

part, in the United States of America (the “U.S.”).

Basis of Presentation

The Condensed Consolidated Financial Statements include the accounts of Energy Recovery, Inc. and its wholly-owned subsidiaries.

All intercompany accounts and transactions have been eliminated in consolidation.

The accompanying Condensed Consolidated Financial Statements have been prepared pursuant to the rules and regulations of the

Securities and Exchange Commission (the “SEC”). Certain information and footnote disclosures normally included in the financial statements

prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) have been condensed or omitted pursuant to such rules

and regulations. The December 31, 2023 Condensed Consolidated Balance Sheet was derived from audited financial statements and may

not include all disclosures required by GAAP; however, the Company believes that the disclosures are adequate to make the information

presented not misleading.

The March 31, 2024 unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited

Consolidated Financial Statements and the notes thereto for the fiscal year ended December 31, 2023 included in the Company’s Annual

Report on Form 10-K filed with the SEC on February 21, 2024 (the “2023 Annual Report”).

All adjustments consisting of normal recurring adjustments that are necessary to present fairly the financial position, results of

operations and cash flows for the interim periods have been made. The results of operations for the interim periods are not necessarily

indicative of the operating results for the full fiscal year or any future periods.

Use of Estimates

The preparation of Condensed Consolidated Financial Statements, in conformity with GAAP, requires the Company’s management to

make judgments, assumptions and estimates that affect the amounts reported in the Condensed Consolidated Financial Statements and

accompanying notes.

The accounting policies that reflect the Company’s significant estimates and judgments and that the Company believes are the most

critical to aid in fully understanding and evaluating its reported financial results are revenue recognition; granted equity award valuations;

equipment useful life and valuation; goodwill valuation and impairment; deferred taxes and valuation allowances on deferred tax assets; and

evaluation and measurement of contingencies. Those estimates could change, and as a result, actual results could differ materially from

those estimates.

The Company is not aware of any specific event or circumstance that would require an update to its estimates or judgments or a

revision of the carrying value of its assets or liabilities as of May 1, 2024, the date of issuance of this Quarterly Report on Form 10-Q. These

estimates may change, as new events occur and additional information is obtained. Actual results could differ materially from these

estimates under different assumptions or conditions. The Company undertakes no obligation to publicly update these estimates for any

reason after the date of this Quarterly Report on Form 10-Q, except as required by law.

Note 7 — Commitments and Contingencies

Litigation

From time-to-time, the Company has been named in and subject to various proceedings and claims in connection with its business.

The Company may in the future become involved in litigation in the ordinary course of business, including litigation that could be material to

its business. The Company considers all claims, if any, on a quarterly basis and, based on known facts, assesses whether potential losses

are considered reasonably possible, probable and estimable. Based upon this assessment, the Company then evaluates disclosure

requirements and whether to accrue for such claims in its consolidated financial statements. The Company records a provision for a liability

when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. These provisions are

reviewed at least quarterly and are adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other

information and events pertaining to a particular case. As of March 31, 2024, the Company was not involved in any lawsuits, legal

proceedings or claims that would have a material effect on the Company’s financial position, results of operations, or cash flows. Therefore,

there were no material losses which were probable or reasonably possible.

Note 8 — Income Taxes


	Three Months Ended March 31,
	2024	2023
(In thousands, except percentages)
Benefit from income taxes	$(1,285)	$(1,159)
Discrete items	76	488
Benefit from income taxes, excluding discrete items	$(1,209)	$(671)
Effective tax rate	13.5%	15.5%
Effective tax rate, excluding discrete items	12.7%	9.0%

The Company’s interim period tax benefit from income taxes is determined using an estimate of its annual effective tax rate, adjusted

for discrete items, if any, that arise during the period. Each quarter, the Company updates its estimate of the annual effective tax rate, and if

the estimated annual effective tax rate changes, the Company makes a cumulative adjustment in such period. The Company’s quarterly tax

provision and estimate of its annual effective tax rate are subject to variation due to several factors, including variability in accurately

predicting its pre-tax income or loss and the mix of jurisdictions to which they relate, intercompany transactions, the applicability of special tax

regimes, and changes in how the Company does business.

For the three months ended March 31, 2024, the recognized benefit from income taxes resulted from the loss for the quarter and

included benefits related to the U.S. federal foreign-derived intangible income (“FDII”) and federal research and development (“R&D”) tax

credit, partially offset by certain permanent differences, such as share-based compensation.

For the three months ended March 31, 2023, the recognized benefit from income tax resulted from the loss for the quarter and

included benefits related to the U.S. FDII and federal R&D tax credit, along with a discrete tax benefit due primarily to share-based

compensation windfalls.

The effective tax rate excluding discrete items for the three months ended March 31, 2024, as compared to the prior year, differed

primarily due to lower projected U.S. FDII and federal R&D tax credits and higher book income, as well as non-deductible officer share-based

compensation and certain foreign-based employee share-based compensation.

Item 2 — Management’s Discussion and Analysis of Financial Condition and Results of

Operations

Overview

Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our” and “us”) designs and manufactures solutions that make

industrial processes more efficient and sustainable. Leveraging our pressure exchanger technology, which generates little to no emissions

when operating, we believe our solutions lower costs, save energy, reduce waste, and minimize emissions for companies across a variety of

commercial and industrial processes. As the world coalesces around the urgent need to address climate change and its impacts, we are

helping companies reduce their energy consumption in their industrial processes, which in turn, reduces their carbon footprint. We believe

that our customers do not have to sacrifice quality and cost savings for sustainability and we are committed to developing solutions that drive

long-term value – both financial and environmental.

The original product application of our technology, the PX® Pressure Exchanger® (“PX”) energy recovery device, was a major

contributor to the advancement of seawater reverse osmosis desalination (“SWRO”), significantly lowering the energy intensity and cost of

water production globally from SWRO. Our pressure exchanger technology is being applied to the wastewater filtration market, such as

battery manufacturers, mining operations, municipalities, and other manufacturing plants that discharge wastewater with significant levels of

metals and pollutants, and has also been applied to the development of our PX G1300® for use in the CO2 market.

Engineering, and research and development (“R&D”), have been, and remain, an essential part of our history, culture and corporate

strategy. Since our formation, we have developed leading technology and engineering expertise through the continual evolution of our

pressure exchanger technology, which can enhance environmental sustainability and improve productivity by reducing waste and energy

consumption in high-pressure industrial fluid-flow systems. This versatile technology works as a platform to build product applications and is

at the heart of many of our products. In addition, we have engineered and developed ancillary devices, such as our hydraulic turbochargers

and circulation “booster” pumps, that complement our energy recovery devices.

Segments

Our reportable operating segments consist of the water and emerging technologies segments. These segments are based on the

industries in which the technology solutions are sold, the type of energy recovery device or other technology sold and the related solution and

service or, in the case of emerging technologies, where revenues from new and/or potential devices utilizing our pressure exchanger

technology can be brought to market. Other factors for determining the reportable operating segments include the manner in which

management evaluates our performance combined with the nature of the individual business activities. In addition, our corporate operating

expenses include expenditures in support of the water and emerging technologies segments. We continue to monitor and review our

segment reporting structure in accordance with authoritative guidance to determine whether any changes have occurred that would impact

our reportable segments.

Results of Operations

A discussion regarding our financial condition and results of operations for the three months ended March 31, 2024, compared to the

three months ended March 31, 2023, is presented below.

Revenue

Variability in revenue from quarter to quarter is typical, therefore year-on-year comparisons are not necessarily indicative of the trend

for the full year due to these variations. There is no specific seasonality in our revenues to highlight that occurs throughout a calendar year.

Total revenue	$12,089	$1	$12,090	$13,296	$105	$13,401

The Megaproject (“MPD”) channel has been the main driver of our long-term growth as revenue from this channel benefits from a

growing number of projects as well as an increase in the capacity of these projects in some cases. The change in revenue for the three

months ended March 31, 2024, as compared to the prior year, was due primarily to customers’ project timing, and execution of these

projects, specifically in the Middle Eastern and Africa (“MEA”) and Americas markets.

The Original Equipment Manufacturer (“OEM”) channel, where we sell into a wide variety of industries in the desalination, wastewater,

and the refrigeration markets, contains projects smaller in size and of shorter duration compared to those projects in the MPD channel.

•Desalination: The decrease in revenue in the three months ended March 31, 2024, as compared to the prior year, by $2.3 million

was due primarily to timing of project shipments in the Asia and MEA markets.

•Wastewater: The decrease in revenue in the three months ended March 31, 2024, as compared to the prior year, by $1.1 million,

was due primarily to timing of project shipments in the Asia market.

The Aftermarket (“AM”) channel revenue generally fluctuates from year-to-year depending on support and services rendered to our

installed customer base. AM revenue is also dependent on our customers’ timing of product upgrades, and replenishment of spare parts and

supplies. Generally, the AM channel revenue has been increasing over time. The increase in revenue in the three months ended March 31,

2024, as compared to the prior year, by $1.3 million was due primarily to shipments to customers in the Middle East, Asia and the Americas

markets.

Statements in Part I, Item 1, “Financial Statements (unaudited),” of this Quarterly Report on Form 10-Q (the “Notes”) for further discussion

regarding our concentration of revenue.

Gross Profit and Gross Margin

Gross profit represents revenue less cost of revenue. Cost of revenue consists primarily of raw materials, personnel costs (including

share-based compensation), manufacturing overhead, warranty costs, depreciation expense and other manufactured components.


	Three Months Ended March 31,
	2024		2023
	Gross Profit	Gross Margin %	Gross Profit	Gross Margin %	Change in Gross Profit
	(In thousands, except percentages)
Gross profit and gross margin	$7,135	59.0%	$8,155	60.9%	$(1,020)	(12.5%)

The decrease in gross profit for the three months ended March 31, 2024, as compared to the prior year, was due primarily to a

decrease in revenue and a slightly lower gross margin. The decrease in gross margin during the three months ended March 31, 2024, as

compared to the prior year, was due primarily to higher manufacturing costs and an increase in inventory scrap, partially offset by lower cost

of product sold related to product mix.

Operating Expenses

The total material changes of general and administrative (“G&A”), sales and marketing (“S&M”) and research and development

(“R&D”) operating expenses for the three months ended March 31, 2024, as compared to the prior year, are discussed within the following

segment and corporate operating expenses discussions below.


	Three Months Ended March 31,

Total operating expenses	$6,767	$6,076	$5,226	$18,069	$6,293	$5,264	$4,709	$16,266

Overall operating expenditures increased by $1.8 million, or 11.1%, in the three months ended March 31, 2024, as compared to the

prior year. This increase was due primarily to higher compensation costs, share-based compensation expense related to additional

headcount, executive transition costs, and an increase in travel costs. Other non-employee costs included:

•G&A: lower consultant costs and professional fees;

•S&M: higher consulting and commission costs, partially offset by lower marketing expenses; and

•R&D: lower facility and other costs.

Water Segment. Water segment operating expenses increased by $0.5 million, or 7.5%, in the three months ended March 31, 2024,

as compared to the prior year. This increase was due primarily to higher employee costs, including share-based compensation expense, in

G&A, S&M and R&D to support our existing desalination operations and our growth in wastewater. In addition, non-employee operating

expenses were higher due primarily to an increase in consultant and commission costs to support our growth in wastewater, partially offset by

lower R&D costs.

Emerging Technologies Segment. Emerging Technologies operating expenses increased by $0.8 million, or 15.4%, in the three

months ended March 31, 2024, as compared to the prior year. This increase was due primarily to higher employee costs and share-based

compensation expense, related to an increase in headcount in G&A, S&M and R&D.

Corporate Operating Expenses. Corporate operating expenses increased by $0.5 million, or 11.0%, in the three months ended

March 31, 2024, as compared to the prior year. This increase was due primarily to higher employee costs and share-based compensation

expense, related to an increase in headcount in G&A and S&M, and an increase in travel costs. In addition, non-employee operating

expenses were lower due primarily to a decrease in consultant costs and professional fees.

Effective tax rate, excluding discrete items	12.7%	9.0%

The interim period tax benefit from income taxes is determined using an estimate of our annual effective tax rate, adjusted for discrete

items, if any, that arise during the period. Each quarter, we update our estimate of the annual effective tax rate, and if the estimated annual

effective tax rate changes, we make a cumulative adjustment in such period. The quarterly tax provision and estimate of our annual effective

tax rate are subject to variation due to several factors, including variability in accurately predicting our pre-tax income or loss and the mix of

jurisdictions to which they relate, intercompany transactions, the applicability of special tax regimes, and changes in how we do business.

For the three months ended March 31, 2024, the recognized benefit from income taxes resulted from the loss for the quarter and

included benefits related to the U.S. federal foreign-derived intangible income (“FDII”) and federal R&D tax credit, partially offset by certain

permanent differences, such as share-based compensation.

For the three months ended March 31, 2023, the recognized benefit from income tax resulted from the loss for the quarter and

compensation windfalls.

The effective tax rate excluding discrete items for the three months ended March 31, 2024, as compared to the prior year, differed

primarily due to lower projected U.S. FDII and federal R&D tax credits and higher book income, as well as non-deductible officer share-based

compensation and certain foreign-based employee share-based compensation.

Liquidity and Capital Resources

Overview

From time-to-time, management and our Board of Directors review our liquidity and future cash needs and may make a decision to

(1) return capital to our shareholders through a share repurchase program or dividend payout; or (2) seek additional debt or equity financing.

As of March 31, 2024, our principal sources of liquidity consisted of (i) unrestricted cash and cash equivalents of $70.8 million; (ii) investment-

grade short-term and long-term marketable debt instruments of $58.7 million that are primarily invested in U.S. treasury securities, corporate

notes and bonds, and municipal and agency notes and bonds; and (iii) accounts receivable, net of allowances, of $25.1 million. As of

March 31, 2024, there was unrestricted cash of $1.0 million held outside the U.S. We invest cash not needed for current operations

predominantly in investment-grade, marketable debt instruments with the intent to make such funds available for future operating purposes,

as needed. Although these securities are available for sale, we generally hold these securities to maturity, and therefore, do not currently see

a need to trade these securities in order to support our liquidity needs in the foreseeable future. We believe the risk of this portfolio to us is in

the ability of the underlying companies or government agencies to cover their obligations at maturity, not in our ability to trade these securities

at a profit. Based on current projections, we believe existing cash balances and future cash inflows from this portfolio will meet our liquidity

needs for at least the next 12 months.

Credit Agreement

We entered into a credit agreement with JPMorgan Chase Bank, N.A. (“JPMC”) on December 22, 2021 (as amended, the “Credit

Agreement”). The Credit Agreement, which will expire on December 21, 2026, provides a committed revolving credit line of $50.0 million and

includes both a revolving loan and a letters of credit (“LCs”) component. The maximum allowable LCs under the credit line component of the

Credit Agreement is $30.0 million. As of March 31, 2024, we were in compliance with all covenants under the Credit Agreement.

Under the Credit Agreement, as of March 31, 2024, there were no revolving loans outstanding. In addition, as of March 31, 2024,

under the LCs component, we utilized $20.3 million of the maximum allowable credit line of $30.0 million, which included newly issued LCs,

and previously issued and unexpired stand-by letters of credits (“SBLCs”) and certain non-expired commitments under the previous Loan and

Pledge Agreement with Citibank, N.A., which are guaranteed under the Credit Agreement. As of March 31, 2024, there was $18.3 million of

outstanding LCs. These LCs had a weighted average remaining life of approximately 14 months.

See Note 6, “Lines of Credit,” of the Notes for further discussion related to the Credit Agreement.

Cash Flows from Operating Activities

Net cash provided by operating activities is subject to the project driven, non-cyclical nature of our business. Operating cash flow can

fluctuate significantly from year to year, due to the timing of receipts of large project orders. Operating cash flow may be negative in one year

and significantly positive in the next, consequently individual quarterly results and comparisons may not necessarily indicate a significant

trend, either positive or negative.

The lower net cash provided by operating assets and liabilities for the three months ended March 31, 2024, as compared to the prior

year, was due primarily to the following factors:

•a decrease in cash provided by accounts receivables related to lower revenues and the timing of collections on the account

receivable balances;

•an increase in cash used for inventory for projects in 2024 and 2025; and

•lower cash used for accounts payable related to the timing of vendor invoices and payments.

Cash Flows from Investing Activities

Net cash (used in) provided by investing activities primarily relates to maturities and purchases of investment-grade marketable debt

instruments, such as corporate notes and bonds, and capital expenditures supporting our growth. We believe our investments in marketable

debt instruments are structured to preserve principal and liquidity while at the same time maximizing yields without significantly increasing

risk. The increase of $6.2 million in net cash used in investing activities in the three months ended March 31, 2024, as compared to the prior

year, was primarily driven by a $5.6 million increase in net cash used for investments in marketable debt instruments and a $0.5 million

increase in cash used for capital expenditures.

Cash Flows from Financing Activities

Net cash provided by financing activities primarily for the three months ended March 31, 2024, as compared to the cash provided by

financing activities in the prior year, was due primarily to higher cash from issuance of equity from our equity incentive plans.

Liquidity and Capital Resource Requirements

We believe that our existing resources and cash generated from our operations will be sufficient to meet our anticipated capital

requirements for at least the next 12 months. However, we may need to raise additional capital or incur additional indebtedness to continue

to fund our operations or to support acquisitions in the future and/or to fund investments in our latest technology arising from rapid market

adoption. These needs could require us to seek additional equity or debt financing. Our future capital requirements will depend on many

factors including the continuing market acceptance of our products, our rate of revenue growth, the timing of new product introductions, the

expansion of our R&D, manufacturing and S&M activities, and the timing and extent of our expansion into new geographic territories. In

addition, we may enter into potential material investments in, or acquisitions of, complementary businesses, services or technologies in the

future which could also require us to seek additional equity or debt financing. Should we need additional liquidity or capital funds, these funds

may not be available to us on favorable terms, or at all.

Recent Accounting Pronouncements

Refer to Note 1, “Description of Business and Significant Accounting Policies – Significant Accounting Policies,” of the Notes to

Condensed Consolidated Financial Statements in Part I, Item 1, “Financial Statements (unaudited),” of this Quarterly Report on Form 10-Q.

Item 3 — Quantitative and Qualitative Disclosures About Market Risk

Our exposure to market risk may be found primarily in two areas, foreign currency and interest rates.

Foreign Currency Risk

Our foreign currency exposures are due to fluctuations in exchange rates for the U.S. dollar (“USD”) versus the British pound, Saudi

riyal, Emirati dirham, European euro, Chinese yuan, Indian rupee and Canadian dollar. Changes in currency exchange rates could adversely

affect our consolidated operating results or financial position.

Our revenue contracts have been denominated in the USD. At times, our international customers may have difficulty in obtaining

the USD to pay our receivables, thus increasing collection risk and potential bad debt expense. To the extent we expand our international

sales, a larger portion of our revenue could be denominated in foreign currencies. As a result, our cash and operating results could be

increasingly affected by changes in exchange rates.

In addition, we pay many vendors in foreign currency and, therefore, are subject to changes in foreign currency exchange rates. Our

international sales and service operations incur expense that is denominated in foreign currencies. This expense could be materially affected

by currency fluctuations. Our international sales and services operations also maintain cash balances denominated in foreign currencies. To

decrease the inherent risk associated with translation of foreign cash balances into our reporting currency, we do not maintain excess cash

balances in foreign currencies.

We have not hedged our exposure to changes in foreign currency exchange rates because expenses in foreign currencies have been

insignificant to date and exchange rate fluctuations have had little impact on our operating results and cash flows. In addition, we do not

have any exposure to the Russian ruble.

Interest Rate and Credit Risks

The primary objective of our investment activities is to preserve principal and liquidity while at the same time maximizing yields without

significantly increasing risk. We invest primarily in investment-grade short-term and long-term marketable debt instruments that are subject

to counter-party credit risk. To minimize this risk, we invest pursuant to an investment policy approved by our Board of Directors. The policy

mandates high credit rating requirements and restricts our exposure to any single corporate issuer by imposing concentration limits.

As of March 31, 2024, our investment portfolio of $58.7 million, in investment-grade marketable debt instruments, such as U.S.

treasury securities, corporate notes and bonds, and municipal and agency notes and bonds, are classified as either short-term and/or long-

term investments on our Condensed Consolidated Balance Sheets. These investments are subject to interest rate fluctuations and decrease

in market value to the extent interest rates increase, which occurred during the three months ended March 31, 2024. To minimize the

exposure due to adverse shifts in interest rates, we maintain investments with a weighted average maturity of approximately nine months. As

of March 31, 2024, a hypothetical 1% increase in interest rates would have resulted in a less than $0.3 million decrease in the fair value of

our investments in marketable debt instruments as of such date.
