Forward-Looking Information
This Quarterly Report on Form 10-Q for the three months ended March 31, 2026, including Part I, Item 2, “Management’s Discussion
and Analysis of Financial Condition and Results of Operations” (the “MD&A”), contains forward-looking statements within the “safe harbor”
provisions of the Private Securities Litigation Reform Act of 1995.  Forward-looking statements in this report include, but are not limited to,
statements about our expectations, objectives, anticipations, plans, hopes, beliefs, intentions or strategies regarding the future.
Forward-looking statements represent our current expectations about future events, are based on assumptions, and involve risks and
uncertainties.  If the risks or uncertainties occur or the assumptions prove incorrect, then our results may differ materially from those set forth
or implied by the forward-looking statements.  Our forward-looking statements are not guarantees of future performance or events.
Words such as “expects,” “anticipates,” “aims,” “projects,” “intends,” “plans,” “believes,” “estimates,” “seeks,” “continue,” “could,”
“may,” “potential,” “should,” “will,” “would,” and variations of such words and similar expressions are also intended to identify such forward-
looking statements.  These forward-looking statements are subject to risks, uncertainties and assumptions that are difficult to predict;
therefore, actual results may differ materially and adversely from those expressed in any forward-looking statement.  Readers are directed to
risks and uncertainties identified under Part II, Item 1A, “Risk Factors,” and elsewhere in this report for factors that may cause actual results
to be different from those expressed in these forward-looking statements.  Except as required by law, we undertake no obligation to revise or
update publicly any forward-looking statement for any reason.
Forward-looking statements in this report include, without limitation, statements about the following:
our belief that our PX offers market-leading value with the highest technological and economic benefit;
our belief that leveraging our pressure exchanger technology will unlock new commercial opportunities in the future;
our belief that our technology helps our customer achieve environmentally sustainable operations;
our expectation that sales outside of the U.S. will remain a significant portion of our revenue;
the scale of the environmental impact from the use of our solutions;
the timing of our receipt of payment for products or services from our customers;
our belief that our existing cash and cash equivalents, our short and/or long-term investments, and the ongoing cash generated
from our operations, will be sufficient to meet our anticipated liquidity needs for the foreseeable future, with the exception of a
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 expectation that we will continue to receive a tax benefit related to U.S. federal foreign-derived intangible income and
research and development tax credit;
the outcome of proceedings, lawsuits, disputes and claims;
the impact of losses due to indemnification obligations;
other factors disclosed under the MD&A and Part I, Item 3, “Quantitative and Qualitative Disclosures about Market Risk,” and
elsewhere in this Form 10-Q.
You should not place undue reliance on these forward-looking statements.  These forward-looking statements reflect management’s
opinions only as of the date of the filing of this Quarterly Report on Form 10-Q.  All forward-looking statements included in this document are
subject to additional risks and uncertainties further discussed under Part II, Item 1A, “Risk Factors,” and are based on information available to
us as of May 6, 2026.  We assume no obligation to update any such forward-looking statements.  Certain risks and uncertainties could cause
actual results to differ materially from those projected in the forward-looking statements.  These forward-looking statements are disclosed
from time to time in our Annual Reports on Form 10‑K, Quarterly Reports on Form 10‑Q and Current Reports on Form 8‑K filed with, or
furnished to, the Securities and Exchange Commission (the “SEC”), as well as in Part II, Item 1A, “Risk Factors,” within this Quarterly Report
on Form 10-Q.

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 world-
class energy-saving technology for critical infrastructure that communities rely on every day, driving a more resilient and sustainable future. 
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
processesAs 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 High-Pressure 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, 2025 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, 2026 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, 2025 included in the Company’s Annual
Report on Form 10-K filed with the SEC on February 25, 2026 (the “2025 Annual Report”).
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.
Reclassifications
Certain prior period amounts have been reclassified in certain notes to the Condensed Consolidated Financial Statements to conform
to the current period presentation.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
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; stock-based compensation expense;
equipment useful life and valuation; goodwill valuation and impairment; inventory valuation and allowances, 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 6, 2026, 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.
Significant Accounting Policies
There have been no material changes to the Company’s significant accounting policies in Note 1, “Description of Business and
Significant Accounting Policies - Significant Accounting Policies,” of the Notes to Consolidated Financial Statements included in Item 8,
“Financial Statements and Supplementary Data,” of the 2025 Annual Report.
Recently Adopted Accounting Pronouncement
In July 2025, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update 2025-05, Measurement of
Credit Losses for Accounts Receivable and Contract Assets (“ASU 2025-05”).  ASU 2025-05 provides a practical expedient for measuring
expected credit losses on current accounts receivables and contract assets by assuming that conditions at the balance sheet date remain
unchanged over the life of the asset. The Company adopted ASU 2025-05 on January 1, 2026 and the adoption did not have a material
impact on results of operations, cash flows, or financial condition.
Recently Issued Accounting Pronouncements Not Yet Adopted
There have been no issued accounting pronouncements that have not yet been adopted during the three months ended March 31,
2026 that apply to the Company other than the pronouncements disclosed in Note 1, “Description of Business and Significant Accounting
Policies - Recently Issued Accounting Pronouncements Not Yet Adopted,” of the Notes to Consolidated Financial Statements included in Item
8, “Financial Statements and Supplementary Data,” of the 2025 Annual Report.

Note 3Loss Per Share
Net loss for the reported period is divided by the weighted average number of basic and diluted common shares outstanding during
the reported period to calculate the basic and diluted loss per share, respectively.  Outstanding stock options to purchase common shares,
unvested restricted stock units (“RSUs”), and unvested performance restricted stock units (“PRSUs”) are collectively referred to as “equity
awards.”
Basic loss per share is computed using the weighted average number of common shares outstanding during the period.
Diluted loss per share is computed using the weighted average number of common and potentially dilutive shares outstanding
during the period, using the treasury stock method.  Any anti-dilutive effect of equity awards outstanding is not included in the
computation of diluted loss per share.
The following table presents the computation of basic and diluted loss per share.

Goodwill
Goodwill is tested for impairment annually in the third quarter of the Company’s fiscal year or more frequently if indicators of potential
impairment exist.  The Company monitors the industries in which it operates and reviews its business performance for indicators of potential
impairment.  The recoverability of goodwill is measured at the reporting unit level, which represents the operating segment. 
In February 2026, the Company wound down operations of the CO2 retail grocery business within its Emerging Technologies
segment due to a fundamental change in the outlook of the business. The Company considered the wind down to be an indicator of
impairment and performed a quantitative impairment test using the discounted cash flow approach and market approach. Based on the
results of the analysis, the Company determined that the carrying value of the reporting unit exceeded its fair value and recorded an
impairment charge of $1.7 million during the three months ended March 31, 2026.

2024 Restructuring Plan
During the fourth quarter of fiscal year 2024, the Company implemented a restructuring plan which included reductions primarily within
the G&A function, in order to lower the Company’s operating cost structure, and to position the Company for profitable growth.  The Company
recorded a restructuring charge of approximately $2.8 million in total, of which $0.5 million was recorded during the three months ended
March 31, 2025. The total restructuring charge recorded relates to severance and benefits, including reemployment assistance, for
38 terminated employees, which was approximately 15% of the Company’s workforce.  The restructuring plan was complete as of December
31, 2025.  All expenses associated with the Company’s restructuring plan are included inRestructuring charges” in the Condensed
Consolidated Statements of Operations.
2026 Restructuring Plan
During the first quarter of fiscal year 2026, the Company wound down operations of the CO2 retail grocery business within its
Emerging Technologies segment due to a fundamental change in the outlook of the business. The Company recorded a restructuring charge
of approximately $1.5 million during the three months ended March 31, 2026. The restructuring charge recorded relates to severance and
benefits, including reemployment assistance, for 23 terminated employees. In addition, the Company incurred other related charges
associated with the wind down of the CO2 retail grocery business, including excess and obsolescence reserves taken on CO2 inventory of
approximately $1.6 million and impairment of goodwill of approximately $1.7 million, which are included in “Restructuring - inventory reserve
and “Impairment of goodwill” in the Condensed Consolidated Statements of Operations, respectively. Refer to section Goodwill within this
footnote for additional information. The restructuring plan was substantially complete by the end of the first quarter of fiscal year 2026 and the
Company does not expect to incur significant additional expenses related to the restructuring.

Note 7Commitments and Contingencies
Sublease
On March 10, 2025, the Company entered into an agreement to sublease its Katy, Texas operating lease. The sublease commenced
on March 10, 2025 and will expire on December 31, 2029. The sublease is classified as an operating lease and has a remaining lease term
of 3.8 years as of March 31, 2026. Sublease income was immaterial during the three months ended March 31, 2026 and 2025, and is
recorded as a reduction of lease expense in general and administrative within the Company’s Condensed Consolidated Statements of
Operations.
The Company considered the sublease to be an indicator of impairment of the original lease. The Company compared the
undiscounted cash flows from the sublease to the carrying value of the Katy, Texas operating lease, which included the associated right-of-
use asset and leasehold improvements. The Company concluded that the carrying value was not recoverable as it exceeded the estimated
undiscounted cash flows.
The Company calculated the impairment charge by comparing the carrying value of the Katy, Texas operating lease to its fair value,
which was calculated based on the net discounted cash flows associated with the sublease. The Company recorded a total impairment
charge of $0.4 million during the three months ended March 31, 2025, of which $0.2 million and $0.2 million was recorded against the right-
of-use asset and the associated leasehold improvements, respectively. The allocation of the impairment charge was based on the relative
carrying value of the assets. The impairment charge was recorded in general and administrative within the Company’s Condensed
Consolidated Statements of Operations.
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, 2026, 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 estimable and accordingly, the Company did not record a provision for
litigation as of March 31, 2026 and December 31, 2025.

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 periodEach 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, the applicability of special tax regimes, and changes in
how the Company does business.
For the three months ended March 31, 2026, the recognized benefit from income taxes resulted from the tax projection based on the
full year forecasted profit and included benefits related to the U.S. federal foreign income and foreign-derived deduction eligible
income (“FDDEI”) federal research and development (“R&D”) tax credit, reduced by certain permanent differences, such as non-deductible
stock-based compensation.
For the three months ended March 31, 2025, the recognized benefit from income taxes resulted from the tax projection based on the
full year forecasted profit and included benefits related to the U.S. federal foreign-derived intangible income (“FDII”), federal R&D tax credit,
certain permanent differences, such as stock-based compensation shortfalls, and partial release of California valuation allowance.
The effective tax rate excluding discrete items for the three months ended March 31, 2026, as compared to the prior year, differed
primarily due to lower projected federal R&D tax credits, increased non-deductible officer stock-based compensation, largely offset by
projected higher U.S. FDDEI benefits.
On July 4, 2025, the One Big Beautiful Bill (“OBBBA”) Act, which includes a broad range of tax reform provisions, was signed into law
in the United States. During the three months ended March 31, 2026, the Company recorded its best estimate of the impact of the OBBBA on
the income tax provision. The Company will continue to evaluate the elections available within the OBBBA, which may impact the timing of
permanent and temporary differences within the Company’s tax provision.

Note 9Segment Reporting
The Company’s Chief Operating Decision-Maker (“CODM”) is its President and Chief Executive Officer.  The Company continues to
monitor and review its segment reporting structure in accordance with authoritative guidance to determine whether any changes have
occurred that would impact its reportable segments.
During the three months ended March 31, 2026, the Company changed the composition of its reportable segments to better reflect
how the CODM manages the business. As a part of this change, the Water segment was separated into two segments, the Desalination
segment and the Wastewater segment, as both met the criteria of a reportable segment. Prior periods have been recast to conform to the
current year presentation. The recast of prior year information had no impact on the Company’s Condensed Consolidated Balance Sheets,
Condensed Consolidated Statements of Operations, Condensed Consolidated Statements of Comprehensive Loss or Condensed
Consolidated Statements of Cash Flows.
Segment Definition
Income and type of expense activities that are included in the Desalination, Wastewater and Emerging Technologies segments and
corporate operating expenses are as follows:
Desalination segment:  The continued development, sales and support of the PX, hydraulic turbochargers and pumps used in
seawater desalination treatment facilities.
Wastewater segment: The continued development, sales and support of the PX, hydraulic turbochargers and pumps used in
wastewater treatment facilities.
Emerging Technologies segment:  The continued development, sales and support of activities related to emerging
technologies, such as the PX G1300 used in industrial and commercial refrigeration applications. In February 2026, the
Company wound down operations of the CO2 retail grocery business within its Emerging Technologies segment due to a
fundamental change in the outlook of the business. As of the first quarter of fiscal year 2026, the Company has substantially
completed the wind down of the business.
Corporate operating expenses:  The corporate expenses include certain unallocated expenses outside of the operating
segments, such as audit and accounting services, legal services, board of director fees and expenses, human resources
activities, information systems activities and other separately managed general expenses not related to the identified
segments.

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 processesAs 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.
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 desalination, wastewater 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 our Chief Operating Decision Maker (“CODM”), our President and Chief Executive Officer, evaluates our performance
combined with the nature of the individual business activities.  In addition, our corporate operating expenses include expenditures in support
of the desalination, wastewater 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.
During the three months ended March 31, 2026, we changed the composition of our reportable segments to better reflect how the
CODM manages the business. As a part of this change, the Water segment was separated into two segments, the Desalination segment and
the Wastewater segment. Prior periods have been recast to conform to the current year presentation.

Results of Operations
A discussion regarding our financial condition and results of operations for the three months ended March 31, 2026, compared to the
three months ended March 31, 2025, is presented below.
Revenue
As a significant portion of our revenue is derived from large project contract deliveries that are up to 36 months from contract date,
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.

Three months ended March 31, 2026, as compared to the three months ended March 31, 2025
The increase in original equipment manufacturer revenue of $2.6 million was due primarily to:
Desalination: The increase in revenue of $2.1 million was due primarily to higher shipments of products to the Europe market and
the Middle East market, partially offset by lower shipments of products to the Africa market.
Wastewater: The increase in revenue of $0.4 million was due primarily to higher shipments of products to the Asia market.
Emerging Tech: The increase in revenue of $0.1 million was due primarily to higher shipments of products to the Americas
market.
The decrease in aftermarket revenue of $1.3 million was primarily due to lower shipments to the Asia and Middle East markets.
The increase in megaproject revenue of $0.3 million was due primarily to higher shipments to the Middle East market.

Three months ended March 31, 2026, as compared to the three months ended March 31, 2025
Overall Operating Expenditures.  Overall operating expenditures increased by $0.5 million, or 3.2%. This increase was due primarily
to impairment of goodwill and restructuring charges incurred as part of the wind down of the CO2 retail grocery business, partially offset by a
decrease in employee costs, as well as consulting costs and impairment costs associated with the sublease of the Katy, Texas lease incurred
during the three months ended March 31, 2025. 
Desalination Segment. Desalination segment related operating expenses increased by $1.3 million, or 32.8%.  This increase was due
primarily to higher employee costs, including stock-based compensation costs, and higher restructuring charges.
Wastewater Segment. Wastewater segment related operating expenses increased by $0.1 million, or 4.6%. This increase was due
primarily to higher consulting costs, partially offset by lower employee costs.

Table of Contents
Emerging Technologies Segment. Emerging Technologies segment related operating expenses increased by $1.1 million, or 27.0%. 
This increase was due primarily to impairment of goodwill and restructuring charges incurred as part of the wind down of the CO2 retail
grocery business, partially offset by lower employee costs, including stock-based compensation costs.
Corporate Operating Expenses.  Corporate operating expenses decreased by $1.9 million, or (27.6%).  This decrease was primarily
due to lower employee costs, consulting costs and impairment costs associated with the sublease of the Katy, Texas lease incurred during
the three months ended March 31, 2025.
Restructuring Charges. During the first quarter of fiscal year 2026, we wound down operations of the CO2 retail grocery business
within our Emerging Technologies segment due to a fundamental change in the outlook of the business. We recorded a restructuring charge
of approximately $1.5 million during the three months ended March 31, 2026. The total restructuring charge recorded relates to severance
and benefits, including reemployment assistance, for 23 terminated employees.  In addition to the restructuring charges, the Company
incurred other related charges associated with the wind down of the CO2 retail grocery business, including excess and obsolescence
reserves taken on CO2 inventory of approximately $1.6 million and impairment of goodwill of approximately $1.7 million, which are included in
Restructuring - inventory reserve” and “Impairment of goodwill” in the Condensed Consolidated Statements of Operations, respectively.
The restructuring plan was substantially complete by the end of the first quarter of fiscal year 2026 and the Company does not expect to incur
significant additional expenses related to the restructuring.
During the fourth quarter of fiscal year 2024, we implemented a restructuring plan which included reductions in our workforce in all
functions of the organization, primarily within the G&A function, in order to lower our operating cost structure, and to position the Company for
profitable growth.  We recorded total restructuring charges of approximately $2.8 million, of which $0.5 million was recorded during the three
months ended March 31, 2025. The total restructuring charge relates to severance and benefits, including reemployment assistance, for
38 terminated employees, which was approximately 15% of our workforce.  The implementation of the restructuring plan was complete as of
December 31, 2025. See Note 4, “Other Financial InformationRestructuring,” of the Notes for further discussion and disclosure on our
restructuring program.

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

For the three months ended March 31, 2026, the recognized benefit from income taxes resulted from the tax projection based on the
full year forecasted profit and included benefits related to the U.S. federal foreign-derived deduction eligible income (“FDDEI”) federal
research and development (“R&D”) tax credit, and certain permanent differences, such as non-deductible stock-based compensation.
For the three months ended March 31, 2025, the recognized benefit from income taxes resulted from the tax projection based on the

certain permanent differences, such as stock-based compensation shortfalls, and partial release of California valuation allowance.
The effective tax rate excluding discrete items for the three months ended March 31, 2026, as compared to the prior year, differed
primarily due to lower projected federal R&D tax credits, increased non-deductible officer stock-based compensation, largely offset by
projected higher U.S. FDDEI benefits.

Liquidity and Capital Resources
Overview
From time-to-time, management and our Board of Directors (the “Board”) 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, 2026, our principal sources of liquidity consisted of (i) unrestricted cash and cash equivalents of $50.1 million that
are held in cash accounts and invested in money market funds and U.S. treasury securities; (ii) investment-grade short-term and long-term
marketable debt instruments of $42.0 million that are primarily invested in U.S. treasury securities and corporate notes and bonds; and
(iii) accounts receivable, net of allowances, of $38.9 million.  As of March 31, 2026, there was unrestricted cash of $0.9 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. on December 22, 2021 (as amended, the “Credit Agreement”). 
The Credit Agreement provides a committed revolving credit line of $50.0 million and includes both a revolving loan and a letters of credit
(“LCs”) component. The Credit Agreement was amended on January 21, 2026 to extend the expiration date from December 21, 2026 to
January 21, 2031. The maximum allowable LCs under the credit line component of the Credit Agreement is $30.0 million.  As of March 31,
2026, the Company was in compliance with all covenants under the Credit Agreement.
See Note 6, “Lines of Credit,” of the Notes for further discussion related to the Credit Agreement.
Share Repurchase Programs
The Board, from time-to-time, has authorized share repurchase programs under which we may, at our discretion, repurchase the
Company’s outstanding common stock in the open market, or in privately negotiated transactions, in compliance with applicable state and
federal securities laws.  The timing and amounts of any purchase under the share repurchase programs are based on market conditions and
other factors including price, regulatory requirements, and capital availability.  We account for stock repurchases under these programs using
the cost method.  As of March 31, 2026, we have cumulatively repurchased 14.9 million shares of the Company’s common stock at an
aggregate cost of $176.8 million under all share repurchase programs.  The following is a discussion of the current share repurchase
program during the three months ended March 31, 2026.  See Note 11, “Stockholders’ EquityShare Repurchase Programs,” of the Notes
for further discussion related to share repurchase programs and a reconciliation of the latest share repurchase plan balance.
On August 6, 2025, we announced that the Board authorized a share repurchase program under which we may repurchase our
outstanding common stock, at the discretion of management, up to $25.0 million in aggregate cost, which includes both the share value of the
acquired common stock and the fees charged in connection with acquiring the common stock (the “August 2025 Authorization”).  We began
repurchasing our outstanding common stock under the August 2025 Authorization in August 2025. The August 2025 Authorization will expire
in May 2026. As of March 31, 2026, we have repurchased 1,346,869 shares of our common stock at an aggregate cost of approximately
$16.3 million of which 960,303 were purchased during the three months ended March 31, 2026 at an aggregate cost of approximately
$10.7 million.
On May 6, 2026, we announced that the Board authorized a share repurchase program under which we may repurchase our
outstanding common stock, at the discretion of management, for up to $25.0 million in aggregate cost, which includes both the share value of
the acquired common stock and the fees charged in connection with acquiring the common stock (the “May 2026 Authorization”).  We expect
to commence repurchasing our outstanding common stock under the May 2026 Authorization in May 2026. The May 2026 Authorization will
expire in April 2027.

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 reporting period to reporting period, due to the timing of receipts of large project orders.  Operating cash flow may
be negative in one reporting period and significantly positive in the next. Consequently, individual reporting period results and comparisons
may not necessarily indicate a significant trend, either positive or negative. 
The higher net cash provided by operating assets and liabilities for the three months ended March 31, 2026, as compared to the prior
year, was due primarily to the following factors: 
Accounts receivable: an increase in cash provided due to an increase in collections related to revenues earned late in the fourth
quarter of 2025;
Accrued liabilities: an increase in cash provided due to incentives and restructuring expenses paid out in 2025, partially offset by,
Inventories: a decrease in cash provided due to cash used to build finished goods inventory in the first quarter of 2026.
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, and capital expenditures supporting our growth. The decrease in cash provided during the three months ended March 31, 2026,
as compared to the prior year, is primarily due to fewer maturities of marketable securities. 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. 
Cash Flows from Financing Activities
Net cash used in financing activities for the three months ended March 31, 2026 was higher as compared to the cash used in
financing activities in the prior year, due to higher repurchases of our common stock partially offset by lower net proceeds from the issuance
of common stock as compared to the prior year.

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.

Table of Contents
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 obtaining
the USD to pay our receivables, thus increasing collection risk and potential bad debt expense.
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 the Board.  The policy mandates
high credit rating requirements and restricts our exposure to any single corporate issuer by imposing concentration limits.
As of March 31, 2026, our investment portfolio of $42.0 million, in investment-grade marketable debt instruments, such as U.S.
treasury securities, and corporate 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 a decrease in market value to the extent
interest rates increase.  To minimize the exposure due to adverse shifts in interest rates, we maintain investments with a weighted average
maturity of approximately six months.  As of March 31, 2026, a hypothetical 1% increase in interest rates would have resulted in a less than
$0.2 million decrease in the fair value of our investments in marketable debt instruments as of such date.

PART II — OTHER INFORMATION
Item 1 — Legal Proceedings
We have been, and may be from time to time, involved in legal proceedings or subject to claims incident to the ordinary course of
business.  We are not presently a party to any legal proceedings that we believe are likely to have a material adverse effect on our business,
financial condition, or operating results.  Regardless of the outcome, such proceedings or claims can have an adverse impact on us because
of defense and settlement costs, diversion of resources and other factors, and there can be no assurances that favorable outcomes will be
obtained.
Item 1A — Risk Factors
Except as noted below, there have been no material changes in our risk factors from those disclosed in Part I, Item 1A, “Risk Factors,”
in the 2025 Annual Report.
Our Water segment revenues largely depend on the construction of new large-scale desalination plants and the retrofit of
existing desalination plants, and as a result, our operating results have historically experienced, and may continue to experience,
significant variability due to volatility in capital spending, availability of project financing, project timing, execution, war or other
hostilities and other factors affecting the broader water desalination industry.
We currently derive the majority of our Water segment revenues from sales of energy recovery products and services used in newly
constructed, large-scale desalination plants and the retrofit of existing desalination plants, particularly in dry or drought-ridden regions of the
world.  The demand for our products used in the Water segment may decrease if the construction of these large-scale desalination plants or
the retrofit of existing plants declines for any reason, including, any global or regional economic downturns, worsening global or regional
political conflicts, war or other hostilities, such as the 2026 conflict in Iran and escalating tensions in the Middle East, worsening regional
conditions, changing government priorities, or the impact of any global or regional conflicts. 
Other factors that could affect the number and capacity of large-scale desalination plants built or the timing of their completion,
include the availability of required engineering and design resources; availability of credit and other forms of financing; the health of the global
economy; inflation rates; changes in government regulation, permitting requirements, or priorities; and reduced capital spending for water
desalination solutions.  Each of these factors could result in reduced or uneven demand for our products.  Pronounced variability, complete
cancellations or delays in the construction of such plants or reductions in spending for desalination in general could negatively impact our
Water segment sales, which in turn could have an adverse effect on our entire business, financial condition, or results of operations, and
make it difficult for us to accurately forecast our future sales.
A sustained downturn in the economy or global unrest could impact the future of new, and the retrofit of existing,
desalination plants, and the treatment of various wastewater verticals, which could result in decreased demand for our water
products and services.
The demand for our water products and services depends primarily on the continued construction of new large-scale desalination
plants, the retrofit of existing plants, and the construction of wastewater treatment facilities, particularly in the countries that are part of the
Gulf Cooperation Council, China, Taiwan and India.  Weak economic conditions, global uncertainty including the continuing conflicts in
Ukraine, the 2026 conflict in Iran and escalating conflicts in the Middle East, as well as the impact of increased inflation resulting from such
conflicts may have a negative economic impact on these and other countries, which may impact the levels of spending on, timing of, delays
to, and availability of, project financing for new desalination and retrofit plant projects.  The inability of our customers to secure credit or
financing for these projects, may result in the postponement or cancellation of these projects.  In addition, the change in government priorities
and/or their reduction in spending for water treatment projects could result in decreased demand for our products and services, which could
have an adverse effect on our business, financial condition or results of operations.
Uncertainty in the global geopolitical landscape and macro-economic environment may impact our operations outside the
U.S., including in the Middle East where many of our water megaprojects are planned.
Energy Recovery, Inc. | Q1'2026 Quarterly Report (Form 10-Q) | 33
Table of Contents
We conduct our business on a global basis.  Our products are sold in numerous countries worldwide, with a large percentage of our
sales generated outside the U.S., specifically in the Middle East and Africa, and Asian markets which provide a significant portion of our total
revenue.  Therefore, we are exposed to, and impacted by, global macroeconomic factors, U.S. and foreign government policies, and foreign
exchange fluctuations.  There is uncertainty surrounding macroeconomic factors in the U.S. and globally characterized by the supply chain
environment, inflationary pressure, rising interest rates, and labor shortages.  These global macroeconomic factors, coupled with the U.S.
political climate, political unrest internationally, and conflicts in Europe and the Middle East, such as the 2026 conflict in Iran and Iran’s
response to attacks by the United States and Israel, have created global economic and political uncertainty, and have impacted demand for
certain of our products.  While the impact and longevity of these factors remain uncertain, we are constantly evaluating the extent to which
these factors will impact our business, financial condition, or results of operations.  Over the long-term, demand for our energy recovery
devices could correlate to global macroeconomic and geopolitical factors.  Any disruption to the economic factors and regulations in these
regions, which remain uncertain, may adversely affect our results of operations and financial condition.
In addition, there is uncertainty as to the position the U.S. will take with respect to world affairs.  This uncertainty may include such
issues as the U.S. support for existing treaty and trade relationships with other countries, including, notably, China, Mexico and Canada.  This
uncertainty, together with other recent key global events, such as currency control regulations and tariff regimes, ongoing terrorist activity,
and hostilities in the Middle East, may adversely impact (i) the ability or willingness of non-U.S. companies to transact business with U.S.
companies, including with us; (ii) our ability to transact business in other countries, including the Middle East, where many of the water
megaprojects are planned; (iii) regulation and trade agreements affecting U.S. companies; (iv) global stock markets (including The NASDAQ
Global Select Market Composite on which our common shares are traded); and (v) general global economic conditions.  Furthermore, the
conflicts in Europe and the Middle East have resulted in worldwide geopolitical and macroeconomic uncertainty, and we cannot predict how
these conflicts will evolve or their timing.  If these conflicts continue for a significant time or further expand to other countries or regions, they
could have additional adverse effects on macroeconomic conditions that may have a direct adverse impact on our business and/or our supply
chain, business partners or customers in the broader region.  All of these factors are outside of our control, but may nonetheless cause us to
adjust our strategy in order to compete effectively in global markets.
