Forward-Looking Information

This Quarterly Report on Form 10-Q for the three and six months ended June 30, 2021, including Part I, Item 2, “Management’s Discussion and Analysis of Financial Condition and Results of Operations” (the “MD&A”) and certain information incorporated by reference, contain 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,” 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 statements. 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 statements for any reason.

Forward-looking statements in this report include, without limitation, statements about the following:

•our belief that the pressure exchanger is the industry standard for energy recovery in the seawater reverse osmosis (“SWRO”) industry;

•our belief that pressure exchanger technology can provide benefits to our customers, including the reduction of capital expenditures and energy use;

•our belief that the integration of Environmental, Social and Governance (“ESG”) principles into our corporate and risk management strategies can strengthen our existing business as well as our efforts to develop new applications of pressure exchanger technology for high-pressure fluid-flow environments;

•our belief that our enhanced safety measures will allow us to help contain the spread of coronavirus (“COVID-19”);

•the development of major public health concerns, including the COVID-19 outbreak or other pandemics arising globally, and the future impact of such major public health concerns, and specifically in the short-term the COVID-19 pandemic, on our business and operations;

•our belief that our pressure exchanger technology can address inefficiencies and waste within industrial systems and processes that involve high-pressure and low-pressure fluid flows;

•our belief that our PX® Pressure Exchanger® (“PX”) has helped make SWRO desalination an economically viable and more sustainable option in the production of potable water;

•our belief that markets not traditionally associated with desalination, including the United States of America (“U.S.”) will inevitably develop and provide further revenue growth opportunities;

•our belief that, as the existing thermal technology is replaced with reverse osmosis (“RO”) technology, demand for our products will be created;

•our belief that ongoing operating costs rather than capital expenditures is the key factor in the selection of an energy recovery device (“ERD”) solution for megaproject (“MPD”) customers;

•our belief that our PX offers market-leading efficiency and reduction of total lifecycle cost to the end client;

•our estimate that MPD customer projects represent revenue opportunities from approximately $1 million to $18 million;

•our belief that initial capital expenditure rather than future ongoing operating costs is the key factor in selection of an ERD solution for original equipment manufacturer (“OEM”) projects;

•our belief that our PX has a competitive advantage, as compared to the Flowserve Corporation’s DWEER product, because our devices are made with highly durable and corrosion-resistant aluminum oxide (“alumina”) ceramic parts that are designed for a life of more than 25 years, are warrantied for high efficiencies, and cause minimal unplanned downtime, resulting in lower lifecycle costs;

Energy Recovery, Inc. | Q2'2021 Form 10-Q | FLS 1

Table of Contents

•our belief that our PX has a distinct competitive advantage over Fluid Equipment Development Company’s (“FEDCO”) turbochargers and Danfoss Group’s iSave ERDs because our devices provide up to 98% efficiency, have lower lifecycle maintenance costs, and are made of highly durable and corrosion-resistant alumina ceramic parts;

•our belief that our Turbochargers compete favorably with FEDCO’s turbochargers based on efficiency, price, and because our Turbochargers have design advantages that enhance efficiency, operational flexibility and serviceability;

•our belief that our existing cash and cash equivalents, our short-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 expectation that we will be able to enforce our intellectual property (“IP”) rights;

•our expectation that the adoption of new accounting standards will not have a material impact on our financial position or results of operations; and

•other factors disclosed under the MD&A and 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, which 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 August 6, 2021. We assume no obligation to update any such forward-looking statements, certain risks and uncertainties which could cause actual results to differ materially from those projected in the forward-looking statements, as 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. It is important to note that our actual results could differ materially from the results set forth or implied by our forward-looking statements. The factors that could cause our actual results to differ from those included in such forward-looking statements are set forth under the heading Item 1A, “Risk Factors,” in our Quarterly Reports on Form 10-Q, and in our Annual Reports on Form 10-K, and from time-to-time, in our results disclosed on our Current Reports on Form 8-K.

We provide our Annual Reports on Form 10‑K, Quarterly Reports on Form 10‑Q, Current Reports on Form 8‑K, Proxy Statements, Forms 3, 4 and 5 filed by or on behalf of directors, executive officers and certain large shareholders, and any amendments to those documents filed or furnished pursuant to the Securities Exchange Act of 1934, free of charge on the Investor Relations section of our website, www.energyrecovery.com. These filings will become available as soon as reasonably practicable after such material is electronically filed with or furnished to the SEC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Note 1 — Description of Business and Significant Accounting Policies

Energy Recovery, Inc. and its wholly-owned subsidiaries (the “Company” or “Energy Recovery”) create technologies that solve complex challenges for industrial fluid-flow markets worldwide. Building on the Company’s pressure exchanger technology platform, the Company designs and manufactures solutions that improve operational efficiency by reducing waste, energy consumption and costs across a range of industrial processes. What began as a game-changing invention for desalination has grown into a global business advancing the environmental sustainability of the Company’s customers’ operations in multiple industries. The Company’s solutions are marketed, sold in, or developed for, the fluid-flow and gas markets, such as water, industrial waste, oil & gas, chemical processing and refrigeration, under the trademarks ERI®, Ultra PX™, PX®, Pressure Exchanger®, PX Pressure Exchanger® (“PX”), PX PowerTrain™, VorTeq™, IsoBoost®, AT™, AquaBold™, and PX G1300™. The Company owns, manufactures and/or develops its solutions, in whole or in part, in the United States of America (“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, 2020 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 June 30, 2021 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, 2020 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 12, 2021 (the “2020 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.

Reclassifications

Certain prior period amounts have been reclassified in the Condensed Consolidated Balance Sheets, Condensed Consolidated Statements of Cash Flows, and certain notes to the Condensed Consolidated Financial Statements, to conform to the current period presentation.

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 more 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; valuation of stock options; valuation and impairment of goodwill; inventory; 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.

ENERGY RECOVERY, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

Due to the novel coronavirus (“COVID-19”) pandemic, and the impact on the Company’s customers, there has been uncertainty and disruption in the global economy and financial markets. 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 August 6, 2021, 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 update publicly these estimates for any reason after the date of this Quarterly Report on Form 10-Q, except as required by law.

Significant Accounting Policies

Except for adopting new accounting pronouncements, as noted under “Recently Adopted Accounting Pronouncements,” there have been no material changes to the Company’s significant accounting policies in Note 1, “Description of Business and Significant Accounting Policies,” of the Notes to Consolidated Financial Statements included in Item 8, “Financial Statements and Supplementary Data,” in the 2020 Annual Report.

Recently Adopted Accounting Pronouncements

In December 2019, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), which simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740 and also clarifies and amends existing guidance to improve consistent application. The new standard is effective for interim and annual periods beginning after December 15, 2020. The Company adopted ASU 2019-12 on January 1, 2021. The adoption of ASU 2019-12 did not have a material impact on the Company’s consolidated financial condition, results of operations, and cash flows.

Recently Issued Accounting Pronouncements Not Yet Adopted

In March 2020, the FASB issued ASU No. 2020-04, Reference Rate Reform (Topic 848) (“ASU 2020-04”), which provided optional expedients and exceptions for applying GAAP to contracts, hedging relationships, and other transactions affected by the discontinuation of the London Interbank Offered Rate (“LIBOR”) or by another reference rate expected to be discontinued. The FASB later issued ASU No. 2021-01, Reference Rate Reform (Topic 848): Scope, to clarify the scope of Topic 848 so that derivatives affected by the discounting transition are explicitly eligible for certain optional expedients and exceptions in Topic 848 (“ASU 2021-01”). Entities may apply the provisions of the new standards as of the beginning of the reporting period when the election is made (i.e., as early as the first quarter of 2020). Unlike other topics, the provisions of this update are only available until December 31, 2022, when the reference rate replacement activity is expected to have been completed. An entity may elect to apply amendments prospectively through December 31, 2022. The optional expedients were available to be used upon issuance of this guidance but the Company has not yet applied the guidance because the Company has not yet modified its existing contract for reference rate reform. The Company does not expect the provisions of ASU 2020-04 or ASU 2021-01 to have a material impact on its financial condition, results of operation, and cash flows.

In June 2020, the Company and Schlumberger Technology Corporation (“Schlumberger”) entered into an agreement to terminate the 2015 license agreement between the Company and Schlumberger (the “VorTeq License Agreement”) to provide Schlumberger with the exclusive worldwide rights to the VorTeq technology. The termination of the VorTeq License Agreement was effective June 1, 2020. As there were no future performance obligations to be recognized under the VorTeq License Agreement after the effective date, the Company recognized in full the remaining deferred revenue balance of $24.4 million in the second quarter of fiscal year 2020. In addition, no future license and development revenue was recognized under the VorTeq License Agreement after the second quarter of fiscal year 2020.

Note 3 — Net Income Per Share

Net income for the reported period is divided by the weighted average number of common shares outstanding during the reported period to calculate basic net income per common share. Basic net income per share excludes any dilutive effect of stock options and restricted stock units ("RSU").

Diluted net income per common share reflects the potential dilution that would occur if outstanding stock options to purchase common stock were exercised for shares of common stock, using the treasury stock method, and the shares of common stock underlying each outstanding RSU were issued (outstanding stock options to purchase common stock and RSUs collectively referred to as, “stock awards”).

The following table presents the computation of basic and diluted net income per share.

Note 5 — Investments and Fair Value Measurements

Available-for-Sale Investments

The Company’s investments in investment-grade short-term high-quality marketable debt instruments, such as U.S. treasury securities, and corporate notes and bonds, are classified as available-for-sale. As of June 30, 2021 and December 31, 2020, available-for-sale investments were classified on the Condensed Consolidated Balance Sheet as short-term investments.

The classification of available-for-sale investments on the Condensed Consolidated Balance Sheet and definition of each of these classifications are provided in Note 1, “Description of Business and Significant Accounting Policies - Significant Accounting Policies,” subsections “Cash and Cash Equivalents” and “Short-term and Long-term Investments,” of the Notes to Consolidated Financial Statements included in Item 8, “Financial Statements and Supplementary Data,” in the 2020 Annual Report.

Expected maturities can differ from contractual maturities because borrowers may have the right to prepay obligations without prepayment penalties. The Company generally holds available-for-sale investments until maturity; however, from time-to-time, the Company may elect to sell certain available-for-sale investments prior to contractual maturity.

Fair Value of Financial Instruments

All of the Company’s financial assets and liabilities are remeasured and reported at fair value at each reporting period; and are classified and disclosed in one of the following three pricing category levels:

Level    1    —    Quoted prices (unadjusted) in active markets for identical assets or liabilities;

Level    2    —    Inputs other than quoted prices included within Level 1 that are either directly or indirectly observable; and

Level    3    —    Unobservable inputs in which little or no market activity exists, thereby requiring an entity to develop its own assumptions that market participants would use in pricing.

The following table presents the Company’s financial assets measured on a recurring basis by contractual maturity, including their pricing category, amortized cost, gross unrealized holding gains and losses, and fair value.

																		June 30, 2021																								December 31, 2020

Note 6 — Lines of Credit

Stand-By Letters of Credit

The Company entered into a loan and pledge agreement with a financial institution during January 2017, which has been amended multiple times to accommodate the growth of the Company (the original loan and pledge agreement and its subsequent amendments are hereinafter referred to as the “Loan and Pledge Agreement”). Under the Loan and Pledge Agreement, the Company is allowed to issue stand-by letters of credit (“SBLCs”) up to one year past the expiration date of the Loan and Pledge Agreement and to hold SBLCs with other financial institutions up to an aggregate amount of $5.1 million. SBLCs have a term limit of three years, are secured by pledged U.S. investments, and do not have any cash collateral balance requirements. SBLCs are deducted from the total revolving credit line under the Loan and Pledge Agreement and are subject to a non-refundable quarterly fee that is in an amount equal to 0.7% per annum of the face amount of the outstanding SBLCs.

As of June 30, 2021 and December 31, 2020, there were outstanding SBLCs of $12.2 million and $13.3 million, respectively.

Purchase Obligations

The Company has purchase order arrangements with its vendors for which the Company has not received the related goods or services as of June 30, 2021. These arrangements are subject to change based on the Company’s sales demand forecasts. The Company has the right to cancel the arrangements prior to the date of delivery. The purchase order arrangements are related to various raw materials and component parts, as well as capital equipment. As of June 30, 2021, the Company had approximately $6.7 million of such open cancellable purchase order arrangements.

Litigation

The Company is named in and subject to various proceedings and claims in connection with its business. The outcome of matters the Company has been, and currently is, involved in cannot be determined at this time, and the results cannot be predicted with certainty. There can be no assurance that these matters will not have a material effect on the Company’s results of operations in any future period, and a significant judgment could have a material impact on the Company’s financial condition, results of operations and cash flows. The Company may in the future become involved in additional litigation in the ordinary course of business, including litigation that could be material to its business.

The Company considers all claims 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 June 30, 2021, there were no material losses which were probable or reasonably possible.

Effective tax rate, excluding discrete items			(5.1		%)				20.1		%				14.8		%				20.0		%

The Company’s tax provision for interim periods 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 and six months ended June 30, 2021, the recognized income tax benefit included a benefit primarily related to the U.S. federal research and development tax credit and a discrete tax benefit due primarily to stock-based compensation windfalls. For the three and six months ended June 30, 2020, the recognized income tax charge included a discrete tax charge related to the termination of the VorTeq License Agreement, partially offset by a discrete tax benefit due primarily to stock-based compensation windfalls.

Note 9 — Stockholders’ Equity

Stock Repurchase Program

On March 9, 2021, the Board of Directors authorized a stock repurchase program under which the Company may repurchase, at the discretion of management, up to $50.0 million in aggregate cost of the Company’s outstanding common stock (the “March 2021 Authorization”). Under the March 2021 Authorization, purchases of shares of common stock may be made from time to time in the open market, or in privately negotiated transactions, in compliance with applicable state and federal securities laws. The timing and amounts of any purchases will be based on market conditions and other factors including price, regulatory requirements, and capital availability. The March 2021 Authorization does not obligate the Company to acquire any specific number of shares in any period, and may be expanded, extended, modified or discontinued at any time without prior notice. The Company accounts for stock repurchases using the cost method. The aggregate cost includes fees charged in connection with acquiring the shares. As of June 30, 2021, 656,938 shares at an aggregate cost of $11.6 million had been repurchased under the March 2021 Authorization.

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

Overview

We create technologies that solve complex challenges for industrial fluid-flow markets worldwide. Building on our pressure exchanger technology platform, we design and manufacture solutions that improve operational efficiency by reducing waste, energy consumption and costs across a range of industrial processes. What began as a game-changing invention for desalination has grown into a global business advancing the environmental sustainability of our customers’ operations in multiple industries. We are a global team with sales and on-site technical support available worldwide, and we maintain international direct sales offices and technical support centers to service the European, Middle Eastern and Asian markets.

Our core technology is the pressure exchanger. Our pressure exchanger technology efficiently transfers energy between high-pressure and low-pressure liquid or gas through continuously rotating ducts. Our PX® Pressure Exchanger® (“PX”) can operate in both low-pressure and high-pressure environments between 1,000 pounds per square inch (“psi”), or 70 bar, and up to approximately 10,000 psi, or 700 bar. Our pressure exchanger technology can also handle a variety of relatively clean to dirty liquids, and we are actively developing capabilities to handle gases. When applied to industrial systems with pressure differentials, pressure exchanger technology can provide certain benefits including our customers’ ability to reduce capital expenditures and energy use, which leads to lower carbon emissions, as well as lower operating costs.

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 improve productivity by reducing waste and energy consumption in high-pressure industrial fluid-flow systems. This versatile technology powers several of our products, including our flagship PX energy recovery device (“ERD”), which we believe is the industry standard for energy recovery in the seawater reverse osmosis desalination (“SWRO”) industry. Today, we continue to push the boundaries of our pressure exchanger technology to handle different operating environments and industrial applications. Leveraging our proven pressure exchanger technology platform, we are identifying new ways to solve, and developing new solutions for solving, challenges for critical industries, such as industrial wastewater treatment, commercial and industrial refrigeration, natural gas processing and hydraulic fracturing.

Quarterly Highlights

Product revenues increased during the quarter and year-to-date, as compared to the same periods in 2020, due primarily to higher sales of PXs, pumps and turbochargers, led by strong sales in the megaproject (“MPD”) and original equipment manufacturers (“OEM”) channels. Total revenues, which are comprised of both product and license and development revenues, were lower for the quarter and year-to-date, as compared to the same periods in 2020, due primarily to the elimination of license and development revenue of which none was recognized after the termination of the VorTeq License Agreement in the second quarter of 2020. Management anticipates continued growth in product revenues as the need to expand potential water production globally is increasing, as well as the increased purchases of product for plant maintenance in advance of the anticipation of the recovery of the economy.

We continue to invest in R&D activities related to bringing the VorTeq™ and PX G1300™ to market. In addition, we are exploring additional usage and markets for the pressure exchanger technology and we expect increased S&M expenditures for the balance of 2021 and early 2022 related to these endeavors.

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. As a result of the evolution of our products, operations and R&D efforts in new product development, such as industrial and commercial refrigeration applications, and the way in which our chief operating decision maker (“CODM”) manages and assesses the performance of the business, starting in the first quarter of fiscal year 2021, we realigned our segment reporting and have recast the prior year amounts for comparability. In addition, to better align the activities of the segments, we have re-allocated certain corporate resources to the segments’ operations.

Water

Our Water segment includes the continued development, sales and support of the PX, hydraulic turbochargers and pumps used in our seawater desalination and industrial wastewater activities. Our Water segment revenue is principally derived from the sale of ERDs and high-pressure and circulation pumps to our MPD, OEM and aftermarket (“AM”) channels. MPD sales are typically made to global engineering, procurement and construction (“EPC”) firms to build very large desalination plants worldwide. Our typical MPD sale primarily consists of our PX ERD. Each MPD sale represents revenue opportunities generally ranging from $1 million to $18 million. Our packaged solutions to OEMs include our PX, hydraulic turbochargers, high-pressure pumps and circulation “booster” pumps for integration and use in small to medium-sized desalination plants. OEM projects typically represent revenue opportunities of up to $1 million. Our existing and expanding installed base of ERD and pump products in water plants has created a growing customer base comprised of plant operators and service providers who purchase spare parts, replacement parts and service contracts through our AM channel.

During the quarter,

•We announced contract awards totaling over $13.8 million for our PX and PX PowerTrain™ systems, supporting the construction of the Sorek B Seawater Reverse Osmosis Desalination Plant in Israel (“Sorek B Plant”). This order is expected to ship between Q3 and Q4 of this year. Once completed, the Sorek B Plant will be the largest SWRO plant and one of the largest facilities in the world, producing 200 million cubic meters per year. The Sorek B Plant is expected to be commissioned between late fiscal year 2022 and early fiscal year 2023.

•We were awarded multiple worldwide MPD and OEM contracts totaling over $55.0 million to supply PXs, related equipment and services.

Emerging Technologies

Our Emerging Technologies segment includes the continued development, sales and support of activities related to emerging technologies, such as the VorTeq used in the oil and gas market, the ISOBoost used in natural gas processing, the PX G1300 used in industrial and commercial refrigeration applications, and certain other new products.

Commercial and Industrial Refrigeration. The global refrigeration industry is a leading user and emitter of hydrofluorocarbons (“HFCs”), which are a group of powerful man-made greenhouse gases that can impact global warming thousands of times more than carbon dioxide (“CO2”). More than 120 countries have signed on to the Kigali Amendment, an amendment to the Montreal Protocol, which states the goal of reducing the production and consumption of HFCs. In 2021, the United States of America (“U.S.”) and China have publicly committed to signing the Kigali Amendment. In addition, the U.S. Environmental Protection Agency announced on May 3, 2021 its intention to reduce the production and consumption of HFCs within the timeline indicated in the Montreal Protocol for developed nations. For the refrigeration industry, phasing out HFCs means moving to natural refrigerants such as ammonia or CO2. CO2 is stable and more benign, and therefore the safer choice; however CO2 works at much higher pressures and requires more energy than HFCs, thereby increasing the operating cost of a CO2 refrigeration system. The challenge today is to make the CO2 refrigeration systems less costly and more efficient in order to compete economically with incumbent refrigerants.

We believe our PX can significantly help reduce the operating costs of CO2 refrigeration systems by recycling the pressure energy of CO2 gas, much as we do with seawater in SWRO, thereby significantly reducing the energy needed to operate these systems. Results from our testing gives us confidence that we will be able to achieve efficiencies across a wider range of temperatures that exceed incumbent CO2 refrigeration technologies, thereby easing this transition to CO2 in the coming years. We will continue development of this technology throughout 2021 with the goal of placing our product in a commercial setting as soon as research, development and testing is completed.

Product Revenue

Variability in product revenue from quarter to quarter is typical, therefore year-on-year quarterly and year-to-date comparisons are not necessarily indicative of the trend for the full year due to these variations. Product revenues by channel customers are presented in the following tables.

			Three Months Ended June 30,

Total product revenue			$	49,547					100		%				$	38,257					100		%				$	11,290					30		%

Our MPD channel continues to be the main driver of our revenue growth during the quarter and year as revenue from this channel benefits from the long project cycle. Increase over prior year is subject to timing of delivery of PXs, which is dependent on the MPD project shipment cycle.

Our OEM channel, where we sell into a number of industries, including tourism and hospitality, and which contains projects of shorter duration, saw a significant increase for the first time since the onset of the COVID-19 pandemic. OEM channel revenues increased due primarily to certain new large greenfield plant installations and brownfield retrofits, which include upgrades to existing operations leveraging our pressure exchanger technology and ancillary equipment. We believe, barring any new shutdown measures caused by the COVID-19 pandemic, this trend will continue into the second-half of 2021. OEM channel revenues in the prior year were negatively affected from delayed new plant construction related to COVID-19.

Our AM channel revenues fluctuate depending on support and services rendered to our customers. AM channel revenues decreased during the quarter; however, increased year-to-date, as compared to the same respective period in the prior year. During the quarter and the first half of the year, we experienced a marked increase in AM activity, which we believe is a result of our customers consuming their existing spare parts inventory and strategically increasing their stock of critical components in advance of greater expected water needs in the second half of 2021 and early 2022. In fiscal year 2020, AM channel revenues were affected by COVID-19 as budgets tightened and companies braced for the unknown.

License and Development Revenue

The change in license and development revenue was due to the termination of the 2015 license agreement (the “VorTeq License Agreement”) between us and Schlumberger Technology Corporation (“Schlumberger”), with an effective date of June 1, 2020. As there were no future performance obligations to be recognized under the VorTeq License Agreement after the effective date, we recognized in full the remaining deferred revenue balance of $24.4 million in the second quarter of fiscal year 2020. In addition, no future license and development revenue was recognized under the VorTeq License Agreement after the second quarter of fiscal year 2020.

Product Gross Profit and Gross Margin

Product gross profit represents our product revenue less our product cost of revenue. Our product cost of revenue consists primarily of raw materials, personnel costs (including share-based compensation), manufacturing overhead, warranty costs, depreciation expense and manufactured components.

			Three Months Ended June 30,
			2021												2020
			$						Gross Margin						$						Gross Margin						Change in Product Gross Profit
			(In thousands, except percentages)
Product gross profit and gross margin			$	13,426					65.1		%				$	12,707					66.0		%				$	719					5.7		%

			Six Months Ended June 30,
			2021												2020

Product gross profit and gross margin			$	33,385					67.4		%				$	26,024					68.0		%				$	7,361					28.3		%

The increase in product gross profit during the three and six months ended June 30, 2021, as compared to the same periods in the prior year, was due primarily to higher revenues related to increased units of PXs, pumps and turbochargers sold, partially offset by a decrease in product gross margin. The gross margin gains from the reduction of the COVID-19 costs that we expensed in 2020 and the operational efficiencies we implemented in the current year were more than offset by rising labor and overhead costs, lower average PX selling prices and a change in product mix.

Operating Expenses

Total Operating Expenses

Operating expenses as a percentage of total revenue was higher in the three and six months ended June 30, 2021, as compared to the same periods in the prior year, due primarily to the acceleration of license and development revenue related to the termination of the VorTeq License Agreement in the second quarter of fiscal year 2020.

			Three Months Ended June 30,
			2021												2020
			$						% of Total Revenue						$						% of Total Revenue						Change

Total operating expenses			$	13,139					64		%				$	15,784					36		%				$	(2,645)					(17		%)

General and Administrative Expenses. General and administrative (“G&A”) expenses increased due primarily to an increase in employee-related costs of $0.6 million and higher consultant costs of $0.1 million. Employee-related costs increased, as compared to the prior year, due primarily to higher employee compensation cost, share-based compensation expense and incentive compensation expense.

Sales and Marketing Expenses. Sales and marketing (“S&M”) expenses increased due primarily to an increase in employee-related costs of $0.8 million, marketing costs of $0.1 million and other costs of $0.1 million. Employee-related costs increased, as compared to the prior year, due primarily to higher employee compensation cost, share-based compensation expense, incentive compensation expense and other employee-related expenses, all related to increased headcount.

Research and Development Expenses. R&D expenses decreased due primarily to lower testing supplies expenditures of $1.6 million as we decreased testing activities on VorTeq and shifted testing activities to refrigeration and other new initiatives, and a reduction in equipment depreciation of $0.3 million primarily related to the impairment of certain VorTeq-related assets in 2020.

Amortization of Intangible Assets. Amortization of intangible assets was comparable to the prior year.

Impairment of Long-lived Assets. During the three months ended June 30, 2020, we conducted an analysis on certain VorTeq long-lived assets that were directly related to obligations under the VorTeq License Agreement and determined that certain of those assets were impaired. The net carrying value of the impaired VorTeq-related machinery and equipment of $2.3 million was recognized in the three months ended June 30, 2020.

General and Administrative Expenses. The increase in G&A expenses was due primarily to higher employee-related costs of $0.2 million and an increase in professional services costs of $0.1 million related to our Environmental, Social and Governance (“ESG”) report costs and legal fees. Employee-related costs increased, as compared to the prior year, due primarily to higher compensation costs incentive compensation expense, and share-based compensation expense, partially offset by lower recruiting costs related to our chief executive officer search in fiscal year 2020, severance costs, and travel costs due primarily to COVID-19.

Sales and Marketing Expenses. The increase in S&M expenses was due primarily to an increase in employee-related costs of $1.2 million and higher marketing costs of $0.2 million, including trade shows and marketing materials, and an increase in other costs of $0.2 million, including commission costs. Employee-related costs increased, as compared to the prior year, due primarily to higher employee compensation costs, share-based compensation expense, incentive compensation expenses, and other employee-related expenses.

Research and Development Expenses. The decrease in R&D expenses was due primarily to lower testing supplies expenditures of $3.5 million related to the reduced development of the VorTeq technology, which fell in the second half of 2020. However, the lower VorTeq-related expenditures in 2021 were partially offset by increased costs to support our incubation initiatives. In addition, R&D expenses in the current year, as compared to the prior year, included a decrease in employee-related costs of $0.3 million, and lower depreciation expenses of $0.3 million primarily related to the impairment of certain VorTeq-related assets in 2020. Employee-related costs decreased, as compared to the prior year, due primarily to lower employee compensation and other employee-related expenses, partially offset by higher incentive compensation expense.

Amortization of Intangible Assets. Amortization of intangible assets was comparable to the prior year.

Impairment of Long-lived Assets. During the three months ended June 30, 2020, we conducted an analysis on certain VorTeq long-lived assets that were directly related to obligations under the VorTeq License Agreement and determined that certain of those assets were impaired. The net carrying value of the impaired VorTeq-related machinery and equipment of $2.3 million was recognized in the three and six months ended June 30, 2020.

Water Segment. The increase in the Water segment operating expenses was due primarily to an increase in S&M costs, driven by increased employee-related costs and higher share-based compensation expense, both related to increased headcount. These costs were partially offset by lower overall G&A and R&D costs, both driven primarily by lower employee-related costs, and a shift of certain R&D costs to emerging technology projects.

Emerging Technologies Segment. The decrease of Emerging Technologies segment operating expenses, was due primarily to reduced VorTeq-related expenditures of $2.3 million, which was partially offset by a shift of expenditures for development of industrial and commercial refrigeration of $0.9 million during the three months ended June 30, 2021. Total VorTeq-related expense was $3.2 million, which included R&D expenditures of $2.4 million.

Corporate Operating Expenses. The increase of corporate operating expenses was due primarily to higher employee incentive compensation expense, share-based compensation expense, legal costs, and other costs, partially offset by lower recruiting costs related to our chief executive officer search in fiscal year 2020.

Total other income, net decreased in the three and six months ended June 30, 2021, compared to the three and six months ended June 30, 2020, due primarily to lower interest income. Our investment strategy in fiscal year 2020 shifted from debt investments to investments in money market funds due primarily to the uncertainty caused by the COVID-19 pandemic.

Income Taxes

Effective tax rate, excluding discrete items			(5.1		%)				20.1		%																14.8		%				20.0		%

The tax provision for interim periods 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 and six months ended June 30, 2021, the recognized income tax benefit included a benefit primarily related to the U.S. federal research and development tax credit and a discrete tax benefit due primarily to stock-based compensation windfalls. For the three and six months ended June 30, 2020, the recognized income tax charge included a discrete tax charge related to the termination of the VorTeq License Agreement, partially offset by a discrete tax benefit due primarily to stock-based compensation windfalls.

Liquidity and Capital Resources

Overview

From time to time, management and our Board of Directors reviews our liquidity and future cash needs and may make a decision on (1) the return of capital to our shareholders through a share repurchase program or dividend payout; or (2) seek additional debt or equity financing. As of June 30, 2021, our principal sources of liquidity consisted of (i) unrestricted cash and cash equivalents of $103.3 million; (ii) investment-grade short-term high-quality marketable debt instruments of $17.4 million that are primarily invested in U.S. treasury securities, and corporate notes and bonds; and (iii) accounts receivable, net of allowances, of $7.6 million. As of June 30, 2021, there were unrestricted cash and cash equivalents of $0.8 million held outside the U.S. We invest cash not needed for current operations predominantly in high-quality, investment-grade, marketable debt instruments with the intent to make such funds available for 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. The risk of this portfolio to us is in the ability of the underlying companies 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.

As of June 30, 2021, we had $0.5 million of short-term contract assets which only represents unbilled trade receivables from certain Water segment contract sales which includes contractual holdback provisions, pursuant to which we will invoice the final retention payment due within the next 12 months. The customer holdbacks represent amounts intended to provide a form of security for the customer; and accordingly, these contract assets have not been discounted to present value. The retention payments with no performance conditions are recorded as trade receivables.

Loan and Pledge Agreement - Stand-By Letters of Credit

We entered into a loan and pledge agreement with a financial institution during January 2017, which has been amended multiple times to accommodate the growth of the Company (the original loan and pledge agreement and its subsequent amendments are hereinafter referred to as the “Loan and Pledge Agreement”). Under the Loan and Pledge Agreement, we are allowed to issue stand-by letters of credit (“SBLCs”) up to one year past the expiration date of the Loan and Pledge Agreement and to hold SBLCs with other financial institutions up to an aggregate amount of $5.1 million. SBLCs have a term limit of three years, are secured by pledged U.S. investments, and do not have any cash collateral balance requirement. SBLCs are deducted from the total revolving credit line under the Loan and Pledge Agreement and are subject to a non-refundable quarterly fee that is in an amount equal to 0.7% per annum of the face amount of the outstanding SBLCs. As of June 30, 2021, outstanding SBLCs totaled $12.2 million.

Share Repurchase Program

On March 9, 2021, our Board of Directors authorized a share repurchase program (the “March 2021 Authorization”) which we may repurchase, under management’s discretion, up to $50.0 million in aggregate cost of our outstanding common stock. As of June 30, 2021, we repurchased 656,938 shares at an aggregate cost of $11.6 million under the March 2021 Authorization. The aggregate cost includes fees charged in connection with acquiring the shares. As of June 30, 2021, under the March 2021 Authorization, we may repurchase, under management’s discretion, additional shares of our outstanding common stock at an aggregate cost of approximately $38.4 million.

Cash Flows

			Six Months Ended June 30,
			2021						2020
			(In thousands)
Net cash provided by (used in) operating activities			$	11,541					$	(294)
Net cash provided by investing activities			383						35,788

Effect of exchange rate differences on cash and cash equivalents			(20)						(15)
Net change in cash, cash equivalents and restricted cash			$	9,047					$	36,584

Cash Flows from Operating Activities

Net cash provided by (used in) 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.

Net cash provided by operating activities for the six months ended June 30, 2021, compared to net cash used in operating activities for the six months ended June 30, 2020, was due primarily to higher product revenues and by the timing of cash collected on accounts receivables, partially offset by increased planned finished goods inventory.

Cash Flows from Investing Activities

Net cash provided by investing activities primarily relates to maturities, sales and purchases of marketable securities, and capital expenditures supporting our growth. Our investments in marketable securities are structured to preserve principal and liquidity while at the same time maximizing yields without significantly increasing risk. The lower cash provided from investing activities for the six months ended June 30, 2021, as compared to cash provided from investing activities in the six months ended June 30, 2020, was due primarily to the movement of our investments in debt securities to cash and cash equivalents in fiscal year 2020 as a result of the COVID-19 pandemic.

Cash Flows from Financing Activities

Net cash (used in) provided by financing activities primarily relates to the issuance of equity from our employee equity incentive plans and offset by share repurchases under our board authorized share repurchase program. Net cash used in financing activities for the six months ended June 30, 2021, was $4.0 million lower than the net cash provided by financing activities for the six months ended June 30, 2020, due primarily to share repurchases of $11.6 million under the March 2021 Authorization, partially offset by higher issuance of equity of $7.6 million related to our employee 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, the timing and extent of our expansion into new geographic territories and the amount and timing of cash used for stock repurchases. 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.

Contractual Obligations

Lease Facilities. We lease facilities and equipment under fixed noncancelable operating leases that expire on various dates through fiscal year 2030.

Purchase Order Arrangements. We have purchase order arrangements with our vendors for which we have not received the related goods or services. These arrangements are subject to change based on our sales demand forecasts. We have the right to cancel the arrangements prior to the date of delivery. The purchase order arrangements are related to various raw materials and component parts, as well as capital equipment.

See Note 7, “Commitments and Contingencies,” of the Notes to Condensed Consolidated Financial Statements in Part I, Item 1, “Financial Statements (unaudited),” of this Quarterly Report on Form 10-Q for additional information related to our fixed noncancelable operating leases and our purchase order arrangements.

Off-Balance Sheet Arrangements

During the periods presented, we did not have any relationships with unconsolidated entities or financial partnerships such as entities often referred to as structured finance or special purpose entities which would have been established for the purpose of facilitating off-balance sheet arrangements or other contractually narrow or limited purposes.

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 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 USD. At times, our international customers may have difficulty in obtaining USD to pay our receivables, thus increasing collection risk and potential doubtful account expense. As we expand our international sales, a 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.

Interest Rate and Credit Risks

We have an investment portfolio of fixed-income marketable debt securities, which are classified as short-term investments on our Condensed Consolidated Balance Sheets. 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 high-quality marketable debt instruments, These investments 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 June 30, 2021, our total debt security investments of $17.4 million are presented in short-term investments on our Condensed Consolidated Balance Sheets. These investments are subject to interest rate fluctuations and will decrease in market value if interest rates increase. To minimize the exposure due to adverse shifts in interest rates, we maintain investments with a weighted average maturity of less than seven months. As of June 30, 2021, a hypothetical 1% increase in interest rates would have resulted in a less than $0.1 million decrease in the fair value of our fixed-income debt securities.

Item 4 — Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Our management, with the participation of our President and Chief Executive Officer and our Chief Financial Officer, have evaluated the effectiveness of our disclosure controls and procedures as defined in Rule 13a-15(e) of the Securities Exchange Act of 1934 as of the end of the period covered by this report.

Based on that evaluation, our President and Chief Executive Officer and our Chief Financial Officer have concluded that, as of June 30, 2021, our disclosure controls and procedures are effective.

Changes in Internal Controls

There were no changes in our internal control over financial reporting during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
