Forward Looking Information

This Quarterly Report on Form 10-Q for the three months ended March 31, 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,” 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 we will be able to identify new ways to solve and develop new solutions for solving challenges for critical industries;
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”);
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 our hydraulic turbochargers (“Turbochargers”) deliver substantial savings and ease of integration into desalination systems;
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 estimate that OEM customer projects represent revenue opportunities up to $1 million;
our belief that our solutions offer a competitive advantage compared to our competitors’ solutions because our ERDs provide the lowest life-cycle cost and are, therefore, the most cost-effective ERD solutions for RO desalination applications;
Energy Recovery, Inc. | Q1’2021 Form 10-Q | FLS 1



Table of Contents
our belief that our PX has a competitive advantage, as compared to the Flowserve Corporation’s (“Flowserve”) 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;
our belief that our PX has a distinct competitive advantage over Fluid Equipment Development Company’s (“FEDCO”) turbochargers and Danfoss Group’s (“Danfoss”) iSave ERD 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 pump solutions are competitive with our competitors because our pumps are developed specifically for RO desalination, are highly efficient, feature product-lubricated bearings, and are often purchased with our ERDs in small to medium-sized plants;
our belief that the VorTeq can allow site operators to reduce repair and maintenance costs, reduce capital costs by extending hydraulic fracturing pump’s life expectancy, and eliminate redundant capital equipment;
our belief that the Ultra PX can address the key challenges associated with treating industrial wastewater in ultra high-pressure reverse osmosis (“UHPRO”) applications;
our belief that the Ultra PX can help make UHPRO the preferred treatment option to achieve zero liquid discharge (“ZLD”) and minimal liquid discharge (“MLD”) requirements by enhancing UHPRO’s affordability and efficiency compared to thermal treatment options;
our objective of finding new applications for our technology and developing new products for use outside of desalination;
our belief that our current facilities will be adequate for the foreseeable future;
our belief that by investing in research and development, the Company will be well positioned to continue to execute on our product strategy;
our belief that our CO2 refrigeration technology will be able to achieve efficiencies across a wider range of temperatures that exceed incumbent CO2 refrigeration technologies, helping customers reduce the operating cost of a natural gas refrigeration system;
the timing of our development and commercialization of our CO2 refrigeration technology;
our expectation that sales outside of the U.S. will remain a significant portion of our revenue;
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-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, as we expand our international sales, a portion of our revenue could be denominated in foreign currencies and the impact of changes in exchange rates on our cash and operating results;
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;
our share repurchase program will result in repurchases of our common stock or enhance long term stockholder value;
the outcome of proceedings, lawsuits, disputes and claims;
the impact of losses due to indemnification obligations;
the impact of changes in internal control over financial reporting;
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; 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.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

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 and AquaBold. 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 significant inter-company 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 (“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 March 31, 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 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.

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 May 7, 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 Company’s 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 VorTeq License Agreement 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”). Certain shares of common stock issuable under stock awards have been omitted from the diluted net income per share calculations because their inclusion is considered anti-dilutive.

Note 5 — Investments and Fair Value Measurements

Available-for-Sale Investments

The Company’s investments in U.S. treasury securities and corporate notes and bonds are classified as available-for-sale. As of March 31, 2021 and December 31, 2020, all available-for-sale investments were either classified as cash equivalents or 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, therefore 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.

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 March 31, 2021, there were no material losses which were probable or reasonably possible.

Effective tax rate(10.3 %)(15.9 %)
Effective tax rate, excluding discrete items15.8 %19.5 %

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 months ended March 31, 2021, the recognized income tax benefit included a discrete tax benefit of $1.6 million, due primarily to stock-based compensation windfalls. For the three months ended March 31, 2020, the recognized income tax benefit included a discrete tax benefit of $0.2 million, 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, at the discretion of management, may repurchase 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 outstanding common stock. As of March 31, 2021, no shares 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, the 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, natural gas processing and hydraulic fracturing.

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 Water segment, we have re-allocated resources to this segment’s operations.

Water Segment

Our Water segment includes sales and marketing (“S&M”) and R&D efforts, and certain general and administrative (“G&A”) activities related to the sales and services of our products for seawater desalination, industrial wastewater, and other water treatment applications. Our Water segment revenue is principally derived from the sale of ERDs and high-pressure and circulation pumps to our megaproject (“MPD”), original equipment manufacturers (“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, 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 our second contract award for our new Ultra PX energy recovery device, which will support the industrial wastewater treatment operations of a natural gas plant in the Sichuan Province of China. Our Ultra PX is designed to dramatically reduce the energy needs, costs and environmental impacts associated with treating industrial wastewater in Ultra High-Pressure Reverse Osmosis (“UHPRO”) applications. Our Ultra PX recovers up to 60 percent of wasted energy when applied to UHPRO systems; and
we announced a joint-marketing effort with DuPont Water Solutions (“DuPont”), a global leader in purification and specialty-separation technologies, to spread the knowledge of advanced solutions improving the efficiency of many industrial wastewater treatment systems. We co-hosted a webinar with DuPont to discuss the benefits of pairing our Ultra PX with DuPont membranes in industrial wastewater treatment systems.

Our Emerging Technologies segment includes our R&D efforts in the continued development of the VorTeq, S&M and R&D efforts to support the sales and development, respectively, of the IsoBoost in natural gas processing, R&D efforts for new product development for other non-water treatment applications, such as industrial and commercial refrigeration applications, and certain emerging technologies-related S&M and G&A activity expenses previously reported under corporate operating expenses.

Commercial and Industrial Refrigeration. The global refrigeration industry is a leading user and emitter of hydro fluorocarbons (“HFCs”), which are a group of powerful man-made greenhouse gases that can impact global warming thousands of times more than CO2. More than 120 countries have signed on to the Kigali Amendment, an amendment to the Montreal Protocol, which states the goal of reducing HFC use by 80% by 2047. This year the United States (“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 HFC emissions in the U.S. by 85% by 2036, 11 years prior to the 2047 Kigali Amendment target, by phasing down the production and import of HFCs. 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 CO2 refrigeration systems less costly and more efficient to compete economically with incumbent refrigerants.

While we are at the early stages of developing this technology, we believe we will be able to achieve efficiencies across a wider range of temperatures that exceed incumbent CO2 refrigeration technologies, helping customers reduce the operating cost of a natural gas refrigeration system and 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.

Results of Operations

A discussion regarding our financial condition and results of operations for the three months ended March 31, 2021, compared to the three months ended March 31, 2020, is presented below.

Product Revenue

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

Total product revenue$28,940 100 %$19,001 100 %$9,939 52 %

Our MPD channel continues to be the main driver of our revenue growth as revenue from this channel benefits from the long project cycle. Our OEM channel, which contains projects of shorter duration, was negatively affected by the economic conditions in late fiscal year 2020 and early 2021, which ultimately delayed certain new installation and upgrade projects, as well as non-critical plant maintenance. Specifically, in our OEM channel, we sell into a number of industries, including tourism and hospitality, which were greatly affected by the COVID-19 pandemic. Our AM channel increased due primarily to an increase in support and services rendered to our large project installed based customers in the first quarter of fiscal year 2021.

License and Development Revenue

The change in license and development revenue was due to the termination of the VorTeq License Agreement. In June 2020, we and Schlumberger Technology Corporation (“Schlumberger”) entered into an agreement to terminate the VorTeq License Agreement effective 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.

(In thousands, except percentages)
Product gross profit and gross margin$19,959 69.0 %$13,317 70.1 %$6,642 49.9 %

The increase in product gross profit was due primarily to higher revenues, partially offset by a reduction in gross margin to 69.0% in the three months ended March 31, 2021, from 70.1% in the three months ended March 31, 2020. The decrease in gross margin was due primarily to lower average selling prices related to product mix and higher manufacturing labor expenses, partially offset by lower COVID-19 related charges.

Total operating expenses$13,815 48 %$15,732 73 %$(1,917)(12 %)

General and administrative expenses. G&A expenses decreased due primarily to a decrease in employee-related costs of $0.4 million, partially offset by higher other costs of $0.2 million. Employee-related costs, as compared to the prior year, decreased due primarily to lower recruiting costs related to our chief executive officer search in fiscal year 2020, partially offset by higher employee incentive compensation and share-based compensation expense.

Sales and marketing expenses. S&M expenses increased due primarily to an increase in employee-related costs of $0.4 million, marketing costs of $0.1 million and other costs of $0.1 million. Employee-related costs, as compared to the prior year, increased due primarily to higher employee compensation expense, share-based compensation expense and annual bonuses paid, partially offset by lower travel expenses.

Research and development expenses. R&D expenses decreased due primarily to lower testing supplies expenditures of $1.9 million as we decreased testing activities on VorTeq and shifted testing activities to refrigeration and other new initiatives.

Segment and Corporate Operating Expenses

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 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 Water segment, we have re-allocated resources to this segment’s operations. Income and type of expense activities that are included in our Water and Emerging Technologies segments and corporate operating expenses are as follows:

Water segment: Includes seawater desalination sales and service, industrial wastewater sales, service, R&D and S&M efforts, other water-related R&D activities, and certain water-related S&M and G&A activity expenses previously reported under corporate operating expenses.
Emerging Technologies segment: Includes R&D efforts in the continued development of the VorTeq, S&M and R&D efforts to support the sales and development, respectively, of the IsoBoost in natural gas processing, and R&D efforts for new product development for other non-water treatment applications, such as industrial and commercial refrigeration applications, and certain emerging technologies-related S&M and G&A activity expenses previously reported under corporate operating expenses.
Corporate operating expenses: Includes certain operating expenses related to corporate activities outside of the operating segments, such as audit and accounting expenses, general legal costs, board of director fees and expenses, and other separately managed general expenses not related to the identified segments.

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

Emerging Technologies segment. The decrease of Emerging Technologies segment operating expenses, was due primarily to reduced VorTeq-related expense of $3.1 million, which was partially offset by a shift of expenditures for development of industrial and commercial refrigeration of $0.8 million during the three months ended March 31, 2021. Total VorTeq-related expense was $3.5 million in the first quarter of fiscal year 2021, which included R&D expenditures of $2.8 million.

Corporate operating expenses. The increase of corporate operating expenses was due primarily to higher employee-related costs primarily related to increased employee incentive compensation, higher 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.

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 months ended March 31, 2021, the recognized income tax benefit included a discrete tax benefit of $1.6 million, due primarily to stock-based compensation windfalls. For the three months ended March 31, 2020, the recognized income tax benefit included a discrete tax benefit of $0.2 million, 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 March 31, 2021, our principal sources of liquidity consisted of: (i) unrestricted cash and cash equivalents of $105.4 million; (ii) short-term investments of $14.6 million that are primarily invested in marketable debt instruments such as corporate notes and bonds and U.S. Treasury securities; and (iii) accounts receivable, net of allowances of $16.4 million. As of March 31, 2021, there were unrestricted cash and cash equivalents of $0.9 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 March 31, 2021, we had $1.1 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 $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 March 31, 2021, outstanding SBLCs totaled $12.9 million.

Share Repurchase Program

On March 9, 2021, our Board of Directors authorized a share repurchase program (the “March 2021 Authorization”) under which we, under management’s discretion, may repurchase up to $50.0 million in aggregate cost of our outstanding common stock. As of March 31, 2021, no shares have been repurchased under the March 2021 Authorization.

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 three months ended March 31, 2021 compared to net cash used in operating activities for the three months ended March 31, 2020, was due primarily to higher revenues, partially offset by the timing of cash collected on accounts receivables.

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 three months ended March 31, 2021, as compared to cash provided from investing activities in the three months ended March 31, 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 provided by financing activities primarily relates to the issuance of equity from our employee equity incentive plans, which for the three months ended March 31, 2021, was higher than the three months ended March 31, 2020.

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 and instruments of the U.S. government including amounts classified as cash equivalents and short-term investments. 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 debt instruments of high-quality corporate issuers and instruments of the U.S. government. 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 March 31, 2021, our total debt security investments which totaled approximately $29.6 million, are presented in cash equivalents and 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 two months. As of March 31, 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 March 31, 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.

Item 1A — Risk Factors

Other than the risk factors provided below, there have been no material changes in our risk factors from those disclosed in Part I, Item 1A, “Risk Factors,” in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2020 filed with the U.S. Securities and Exchange Commission on March 12, 2021.

Our diversification into new fluid flow markets, such as oil & gas, commercial refrigeration and industrial wastewater, may not be successful.

We have made a substantial investment in research, development, and sales to execute on our diversification strategy into fluid flow markets such as oil & gas, commercial refrigeration and industrial wastewater. While we see diversification as core to our growth strategy, there is no guarantee that we will be successful in our efforts. Our model for growth is based in part on our ability to initiate and embrace disruptive technology trends, to enter new markets, both in terms of geographies and product areas, and to drive broad adoption of the products and services that we develop and market. Any inability to execute this model for growth could damage our reputation, limit our growth, and negatively affect our operation results. For example, while we believe that our products will enable gas processing plant operators to operate at a high level of energy efficiency with minimal downtime, we may be subject to warranty claims if customers of these offerings experience significant downtimes or failures for which our warranty reserves may be inadequate given the lack of historical failure rates associated with new product introductions. We also could be subject to damage claims based on our products, which we may not be able to properly insure. In addition, profitability, if any, in new industrial verticals may be lower than in our Water segment, and we may not be sufficiently successful in our diversification efforts to recoup investments.

We may not be able to successfully complete development, launch or commercialization of our C02 refrigeration technology.

We are currently developing PX based technology for use in CO2 commercial refrigeration. The technology is in the R&D phase. While initial testing of the technology has been promising, CO2 commercial refrigeration is complex and presents a wide range of technological challenges for us. We may not be successful in solving these challenges and, as a result, may not be able to successfully complete development of or launch the technology. Even if we are able to complete development, we may not be able to generate sufficient interest in our technology or commercialize the technology. The commercial refrigeration industry is also saturated with very large, established companies who have greater experience and resources than us. If we are unable to solve the technological challenges, complete development, launch and generate sufficient interest for our CO2 refrigeration technology, we may not be able to successfully commercialize the technology, which could have an adverse effect on our entire business, financial condition, or results of operation.
