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,” “Energy Recovery,” “our,” “us,” or “we”) is an energy solutions provider to industrial fluid flow markets worldwide. The Company’s core competencies are fluid dynamics and advanced material science. The Company’s products make industrial processes more operationally and capital expenditure efficient. The Company’s solutions convert wasted pressure energy into a reusable asset and preserve or eliminate pumping technology in hostile processing environments. The Company’s solutions are marketed and sold in fluid flow markets, such as water, oil & gas, and chemical processing, under the trademarks ERI®, PX®, Pressure Exchanger®, PX Pressure Exchanger®, VorTeq™, MTeq™, IsoBoost®, IsoGen®, 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 Company’s 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 by the Company, 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, 2018 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, 2019 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, 2018 included in the Company’s Annual Report on Form 10-K filed with the SEC on March 7, 2019, as amended on March 12, 2019.

In the opinion of management, all adjustments, consisting of normal recurring adjustments that are necessary to present fairly the financial position, results of operations, and cash flows for the interim periods, have been made. The results of operations for the interim periods are not necessarily indicative of the operating results for the full fiscal year or any future periods.

Use of Estimates

The preparation of Condensed Consolidated Financial Statements in conformity with U.S. 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 to Condensed Consolidated Financial Statements.

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; capitalization of research and development assets; valuation of stock options; valuation and impairment of goodwill and acquired intangible assets; valuation adjustments for excess and obsolete 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.

Recent Accounting Pronouncements

Recently Adopted Accounting Pronouncements

There were no material accounting pronouncements adopted during the quarter ended March 31, 2019.

ENERGY RECOVERY, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Recently issued accounting pronouncements not yet adopted

In August 2018, the Financial Accounting Standards board (“FASB”) issued Accounting Standards Update (“ASU”) 2018-15 (“ASU 2018-15”), Intangibles - Goodwill and Other - Internal-Use Software (Topic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract. ASU 2018-15 aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software. The updated guidance is effective for annual periods beginning after December 15, 2019, and interim periods within those fiscal years, and early adoption is permitted. At this time, we are still evaluating the impact of adopting this standard on our financial statements.

Note 3 — Income (Loss) Per Share

Net income (loss) is divided by the weighted average number of common shares outstanding during the year to calculate basic net income (loss) per common share. Basic earnings per share exclude any dilutive effects of stock options and restricted stock units (“RSUs”).

Diluted net income (loss) 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. Diluted earnings per share for the three months ended March 31, 2019 and 2018, includes the dilutive effects of stock options and RSUs. Certain shares of common stock issuable under stock options and RSUs have been omitted from the three months ended March 31, 2019 and 2018 diluted net income per share calculations because their inclusion is considered anti-dilutive.

The computation of basic and diluted net income (loss) per share is presented in the following table.

Fair Value of Financial Instruments

Financial assets and liabilities that are remeasured and reported at fair value at each reporting period are classified and disclosed in one of the following three 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.

ENERGY RECOVERY, INC.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

For the Company’s investments in available-for-sale securities, if quoted prices in active markets for identical investments are not available to determine fair value (Level 1), then the Company uses quoted prices for similar assets or inputs other than quoted prices that are observable either directly or indirectly (Level 2). The investments included in Level 2 consist of corporate notes and bonds, and U.S. Treasury securities.

The fair value of financial assets and liabilities measured on a recurring basis is presented in the following tables.

Note 7 — Lines of Credit

Loan and Pledge Agreement

On January 27, 2017, the Company entered into a loan and pledge agreement (the “Loan and Pledge Agreement”) with a financial institution. The Loan and Pledge Agreement provides for a committed revolving credit line of $16.0 million and an uncommitted revolving credit line of $4.0 million. The Loan and Pledge Agreement was amended on March 30, 2018 to extend the termination date of the Loan and Pledge Agreement from March 31, 2018 to March 31, 2020, in connection with which the Company paid closing fees of $16 thousand. The Loan and Pledge Agreement was further amended on August 24, 2018 to permit the Company to incur indebtedness owed to a foreign subsidiary in an aggregate amount not to exceed $66.0 million, which amount is subordinated to any amounts outstanding under the Loan and Pledge Agreement. The Loan and Pledge Agreement was subsequently amended on April 8, 2019 to clarify definitions of certain terms and to allow the term of any Letter of Credit to not exceed two years instead of 364 days from the date of issuance, and in addition to permit the Company to issue Standby Letters of Credit (“SBLCs”) up to one year past the expiration date of the loan agreement. On April 23, 2019, the Loan and Pledge Agreement was amended further to clarify definition of certain additional terms. As of March 31, 2019, no debt was outstanding under the Loan and Pledge Agreement, however, the standby letters of credit are deducted from the total revolving credit line.

Stand-by Letters of Credit

The outstanding amounts of stand-by letters of credit are $10.7 million at March 31, 2019.

Note 8 — Commitments and Contingencies

Operating Lease Obligations

The Company leases office facilities and equipment under operating leases that expire on various dates through 2029.

On January 10, 2019, the Company entered into an industrial lease agreement (the lease was executed but has not commenced as of March 31, 2019) pursuant to which the Company has leased approximately 25,200 square feet to be constructed office and warehouse space and approximately 4.5 acres of yard space in Katy, Texas, for a new commercial development center for oil & gas field testing and training. The Company’s monthly base rent obligation is approximately $26,000 for the first year of the lease and increases three percent annually thereafter. The future lease payments are approximately $26,000 for the remainder of 2019, $317,000 for year two, $326,000 for year three, $336,000 for year four, $347,000 for year five and $2,204,000 for all years thereafter. In addition, the Company will pay its share of operating expenses, which is currently estimated to be approximately $12,000 per month. The initial term of the Lease is one hundred twenty (120) months after the commencement date (expected to be in the second half of the year), and the Company has two options to extend the Lease by an additional five-year term, which must be exercised by written notice at least six months prior to the end of the relevant term. Maturities of the lease liabilities as of March 31, 2019 (excluding the new lease referenced above that is executed but will not commence until the second half of the year), are presented in the following table.

These arrangements are subject to change based on the Company’s sales demand forecasts, and the Company has the right to cancel the arrangements prior to the date of delivery. The majority of these purchase order arrangements were related to various raw materials and components parts. As of March 31, 2019, the Company had approximately $8.4 million of open cancellable purchase order arrangements related primarily to materials and parts.

Guarantees

The Company enters into indemnification provisions under its agreements with other companies in the ordinary course of business, typically with customers. Under these provisions, the Company generally indemnifies and holds harmless the indemnified party for losses suffered or incurred by the indemnified party as a result of the Company’s activities, generally limited to personal injury and property damage caused by the Company’s employees at a customer’s desalination plant in proportion to the employee’s percentage of fault for the accident. Damages incurred for these indemnifications would be covered by the Company’s general liability insurance to the extent provided by the policy limitations. The Company has not incurred material costs to defend lawsuits or settle claims related to these indemnification agreements. As a result, the estimated fair value of these agreements is not material. Accordingly, the Company had no liabilities recorded for these agreements as of March 31, 2019 and December 31, 2018.

In certain cases, the Company issues warranty and product performance guarantees to its customers for amounts generally equal to 10% or less of the total sales agreement to endorse the execution of product delivery and the warranty of design work, fabrication, and operating performance of our devices. These guarantees are generally stand-by letters of credit that typically remain in place in general for periods of 24 to 36 months. All stand-by letters of credit at March 31, 2019 and December 31, 2018, were in the aggregate for amounts of $10.7 million and $8.8 million, respectively.

Litigation

The Company is named in and subject to various proceedings and claims in connection with our business. The outcome of matters the Company has been, and currently are, 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 adverse effect on our 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 its 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 adjusted to reflect the impacts of negotiations, settlements, rulings, advice of legal counsel and other information and events pertaining to a particular case.

On September 10, 2014, the Company terminated the employment of its Senior Vice President, Sales, Borja Blanco, on the basis of breach of duty of trust and conduct leading to conflict of interest. On October 24, 2014, Mr. Blanco filed a labor claim against ERI Iberia in Madrid, Spain, challenging the fairness of his dismissal and seeking compensation. A hearing was held on November 13, 2015, after which the labor court ruled that it did not have jurisdiction over the matter. Mr. Blanco appealed and the appeals court reversed the labor court’s finding and instructed the labor court to make a ruling on the merits on November 21, 2017. On February 14, 2018, the Company received notice that the labor court issued a ruling in favor of Mr. Blanco and ordered the Company to pay to Mr. Blanco a severance amount. The Company appealed and on March 18, 2019, the Company received notice that the appeals court had partially reversed the labor court’s order and significantly reduced the severance amount. The Company again appealed the decision on April 24, 2019. The Company denies any allegations of wrongdoing and intends to continue to vigorously defend against this lawsuit. Based on currently available information and review with outside counsel, the Company had previously estimated and accrued for a potential loss. The Company does not believe that it is reasonably possible that a material loss in excess of amounts accrued will occur.

Note 9 — Income Taxes

The effective tax rate for the three months ended March 31, 2019 and 2018 was 17.3% on pretax book income of $3.2 million and 33.0% on pretax book loss of $1.1 million, respectively. Excluding stock option related discrete tax income tax benefits of $0.1 million in the current period and $0.4 million in the prior year period, the effective tax rate for the three months ended March 31, 2019 and 2018 was 21.3% and (3.5)%, respectively. The tax rate in the three months ending March 31, 2019 is lower than the tax rate in the three months ending March 31, 2018 as a result of the Company reporting losses of $1.3 million in the prior year period in a jurisdiction for which the Company could not recognize a tax benefit due to a full valuation allowance in this jurisdiction.

Total stock-based compensation expense	$	1,678	$	2,243


⁽¹⁾	2018 Amounts include modifications of equity awards held by the Company’s former Chief Executive Officer.

The Company estimates forfeitures at the time of grant and revises those estimates periodically in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and record stock-based compensation expense only for those awards that are expected to vest. All stock-based payment awards are amortized on a straight-line basis over the requisite service periods of the awards, which are generally the vesting periods. If the Company’s actual forfeiture rate is materially different from its estimate, the stock-based compensation expense could be significantly different from what the Company has recorded in the current period.

Modifications of Equity Awards

In the first quarter of 2018, the Company recorded additional stock-based compensation expense of $0.9 million due to an equity award modification charge chiefly related to the modification of certain equity awards held by the Company’s former President and Chief Executive Officer, who resigned on February 24, 2018, in consideration for his entering into a Settlement Agreement and Release.

Unamortized Stock-based Compensation Costs

Stock-based compensation cost related to unvested stock options and RSUs will generally be amortized on a straight-line basis over the remaining average service period of each award.

Overview

Energy Recovery, Inc. (the “Company”, “Energy Recovery”, “we”, “our” and “us”) (NASDAQ: ERII) is an engineering-driven technology company that engineers, designs, manufactures and supplies solutions for industrial fluid flow processes. The Company offers technologies which can drive meaningful, immediate cost savings and operational efficiencies for our customers. Currently, we operate in two markets - water and oil & gas, and our products are utilized in these markets to either recycle and convert wasted pressure energy into a usable asset or preserve pumps that are subject to hostile processing environments.

Energy Recovery was incorporated in Virginia in 1992 and reincorporated in Delaware in 2001. Our headquarters and principal research, development, and manufacturing facility is located in California. We are also constructing a new facility in Texas, which we hope to complete in 2019, for a new commercial development center for Oil & Gas field testing and training. We maintain direct sales offices and technical support centers in Europe, the Middle East and Asia.

Our reportable operating segments consist of the Water and the Oil & Gas segments. These segments are based on the industries in which the technology solutions are sold, the type of energy recovery device or other technology sold, and the related solution and service.

Water Segment

Our Water segment consists of revenues and expenses associated with solutions sold for use in seawater, brackish, and wastewater reverse osmosis desalination. Our Water segment revenue is principally derived from the sale of energy recovery devices (“ERDs”) and high-pressure and circulation pumps to our mega-project (“MPD”), original equipment manufacturer (“OEM”), and After-Market (“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 consists of our PX Pressure Exchangers, and each MPD represents revenue opportunities generally ranging from $1 million to $10 million. Our packaged solutions to OEMs include PXs, 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.

Oil & Gas Segment

Our Oil & Gas segment consists of revenues and expenses associated with solutions sold or licensed for use in hydraulic fracturing, gas processing, and chemical processing. In the past several years, we have invested significant research and development, and sales and marketing costs to expand our business into pressurized fluid flow industries within the oil & gas industry. Our revenue in the first quarter of 2019 is primarily from license and development revenue.

Total revenue	$	19,795	100	%	$	13,807	100	%	$	5,988	43	%

Product Revenue by Segment

Total product revenue increased by $5.0 million, or 45%, to $16.1 million for the three months ended March 31, 2019 from $11.1 million for the three months ended March 31, 2018. Of the $5.0 million increase, $4.9 million was attributable to the Water Segment and $0.1 million was attributable to the Oil & Gas Segment.

During the three months ended March 31, 2019, compared to the three months ended March 31, 2018, Water segment product revenue increased by $4.9 million, or 45%, due primarily to an increase of $6.4 million of MPD shipments, offset by $0.9 million of lower OEM shipments and $0.6 million of lower AM shipments. Revenues in the first three months were significantly higher than in 2018 due to the timing of MPD shipments. Significant variability quarter to quarter is typical, and year on year quarterly comparisons are not necessarily indicative of the trend for the year due to these variations.

During the three months ended March 31, 2019, compared to the three months ended March 31, 2018, Oil & Gas segment product revenue increased by $0.1 million.

License and Development Revenue

License and development revenue increased by $1.0 million, or 35%, in the three months ended March 31, 2019, compared to the three months ended March 31, 2018, due primarily to higher costs incurred based on input measure of progress.

Product Gross Profit and Margin



	Three Months Ended March 31, 2019			Three Months Ended March 31, 2018
	Water	Oil & Gas	Total	Water	Oil & Gas	Total

Product gross margin	70.3%	(80.8%)	69.3%	70.8%	(760.0%)	70.0%

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

In the three months ended March 31, 2019, compared to the three months ended March 31, 2018, product gross profit increased $3.4 million, or 44%, due primarily to a favorable $4.8 million impact from higher MPD volume, offset somewhat by unfavorable impacts of $0.5 million from lower OEM volume, a $0.5 million impact from lower AM volume, and an unfavorable price and mix impact of $0.5 million.

– 33 –

Product gross margin was 69% in the three months ended March 31, 2019, compared to the product gross margin of 70% in the three months ended March 31, 2018.

Operating income was $7.7 million for the three months ended March 31, 2019 compared to $3.7 million for the three months ended March 31, 2018, an increase of $4.0 million, due primarily to an increase of total product revenue of $5.0 million (attributable to the Water Segment) and an increase of $1.0 million in license and development revenue.

Operating Expenses

General and Administrative

General and administrative expense decreased $0.3 million, or (4%), in the three months ended March 31, 2019, compared to the three months ended March 31, 2018, due primarily to a decrease in total employee-related compensation and benefits of $0.3 million. The net decrease in employee-related compensation and benefits of $0.3 million is due to a $0.4 million increase in compensation generally and a $0.7 million reduction in stock based compensation costs in the current period resulting mostly from a non-recurring charge related to the modification of certain equity awards held by the Company’s former President and Chief Executive Officer in the three months ended March 31, 2018, who resigned on February 24, 2018 and entered into a Settlement Agreement and Release.

Sales and Marketing

For the three months ended March 31, 2019, compared to the three months ended March 31, 2018, sales and marketing expense increased by $0.2 million, or 13%, due primarily to higher sales incentive expenses in the water segment.

Research and Development

For the three months ended March 31, 2019, compared to the three months ended March 31, 2018, research and development expense increased by $0.3 million, or 9%, due primarily to higher employee related expenses of $0.4 million from increased investment in water growth initiatives, slightly offset by the timing of VorTeq R&D testing expenses.

Amortization of Intangible Assets

Amortization of intangible assets is related to finite-lived intangible assets acquired as a result of our purchase of Pump Engineering, LLC in December 2009. There was no material change in our amortization amounts in the three months ended March 31, 2019, compared to the three months ended March 31, 2018.

Total other income, net	$	499		3	%	$	248		2	%	$	251	101	%

Total other income (expense), net, increased in the three months ended March 31, 2019, compared to the three months ended March 31, 2018, due primarily to interest income on higher investment balances.

Income Taxes

The effective tax rate for the three months ended March 31, 2019 and 2018 was 17.3% on pretax book income of $3.2 million and 33.0% on pretax book loss of $1.1 million, respectively. Excluding stock option related discrete tax income tax benefits of $0.1 million in the current period and $0.4 million in the prior year period, the effective tax rate for the three months ended March 31, 2019 and 2018 was 21.3% and (3.5%), respectively. The tax rate in the three months ending March 31, 2019 is lower than the tax rate in the three months ending March 31, 2018 as a result of the Company reporting losses of $1.3 million in the prior year period in a jurisdiction for which the Company could not recognize a tax benefit due to a full valuation allowance in this jurisdiction.

Liquidity and Capital Resources

Overview

Our primary source of cash to fund our operations and capital expenditures has been proceeds from customer payments for our products and services and the issuance of common stock.

As of March 31, 2019, our principal sources of liquidity consisted of : (i) unrestricted cash and cash equivalents of $17.0 million that are primarily invested in money market funds, (ii) short-term investments of $71.8 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 $17.4 million. 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.

At March 31, 2019 and December 31, 2018, we had $1.1 million and $4.1 million, respectively, of short-term contract assets which represents unbilled receivables. In the Water segment, we had contract assets of $1.1 million pertaining to customer contractual holdback provisions, whereby we will invoice the final retention payment(s) due under certain sales contracts in the next 12 months. The customer holdbacks represent amounts intended to provide a form of security for the customer; accordingly, these contract assets have not been discounted to present value. In the Oil & Gas segment, there were no unbilled project costs at March 31, 2019.

Loan Agreements

On January 27, 2017, we entered into a loan and pledge agreement (the “Loan and Pledge Agreement”) with a financial institution. The Loan and Pledge Agreement provides for a committed revolving credit line of $16.0 million and an uncommitted revolving credit line of $4.0 million. Under the Loan and Pledge Agreement, we are allowed to borrow and request letters of credit against the eligible assets held from time to time in the pledged account maintained with the financial institution.

The Loan and Pledge Agreement was amended on March 30, 2018 to extend the termination date of the Loan and Pledge Agreement from March 31, 2018 to March 31, 2020. The Loan and Pledge Agreement was further amended on August 24, 2018 to permit the Company to incur indebtedness owed to a foreign subsidiary in an aggregate amount not to exceed $66.0 million, which amount is subordinated to any amounts outstanding under the Loan and Pledge Agreement. The Loan and Pledge Agreement was subsequently amended on April 8, 2019 to clarify definitions of certain terms and to allow the term of any Letter of Credit to not exceed two years instead of 364 days from the date of issuance, and in addition to permit the Company to issue Standy Letter of Credit (“SBLCs”) up to one year past the expiration date of the loan agreement. On April 23, 2019, the Loan and Pledge Agreement was amended further to clarify definition of certain additional terms.

As of March 31, 2019, no debt was outstanding under the Loan and Pledge Agreement, however, the SBLCs outstanding are deducted from the total revolving credit line. See our 2018 Annual Report on Form 10-K. As of March 31, 2019, we were in compliance with the loan covenants.

Stand-by Letters of Credit

As of March 31, 2019, we had SBLCs with various financial institutions totaling $10.7 million whereby we are required to maintain a U.S. investment balance of $10.6 million. SBLCs are subject to fees based on the amount of the letter of credit that are payable quarterly and are non-refundable.

Share Repurchase Programs

Our Board of Directors has authorized various share repurchase programs since 2012. On March 7, 2018, our Board of Directors authorized a share repurchase program (the “March 2018 Authorization”) under which the Company, at the discretion of management, may repurchase up to $10.0 million in aggregate cost of our outstanding common stock through September 30, 2018. As of March 31, 2019, we have repurchased 1,193,102 shares for $10.0 million under the March 2018 Authorization. Since the initial authorization of the share repurchase programs, we have spent an aggregate $30.4 million, excluding commissions, to repurchase 5.5 million shares. The March 2018 Authorization expired in September 2018 and no other authorization is in place today.

Cash Flows

Our cash flows are presented in the following table.



	Three Months Ended March 31,
	2019			2018
	(In thousands)
Net cash used in operating activities	$	(5,951	)	$	(6,333	)
Net cash (used in) provided by investing activities	(1,165		)	11,062
Net cash provided by (used in) financing activities	2,157			(1,898		)
Effect of exchange rate differences on cash and cash equivalents	(4		)	(14		)
Net change in cash, cash equivalents and restricted cash	$	(4,963	)	$	2,817

Cash Flows from Operating Activities

Cash used in operating activities is generated by net income (loss) adjusted for certain non-cash items and changes in assets and liabilities.

Cash used in operating activities was lower in the three months ended March 31, 2019, compared to the cash used in three months ended March 31, 2018, by $0.4 million, primarily due to the increase in income net, as adjusted for some non-cash items, timing of collection, billing and shipment.

Due to the project driven, non-cyclical nature of our business, operating cash flow can fluctuate significantly from quarter to quarter due to the timing of receipts of large project orders. Operating cash flow may be negative in one quarter, and significantly positive in the next, and year-on-year quarterly comparisons are difficult to compare. Therefore, it may be difficult to derive meaning directly from quarterly comparisons of cash flow.

Cash Flows from Investing Activities

Cash flows from investing activities primarily relate to maturities and purchases of marketable securities to preserve principal and liquidity while at the same time maximizing yields without significantly increasing risk, capital expenditures to support our growth, and changes in our restricted cash used to collateralize our stand-by letters of credit and other contingent considerations.

Cash used in investing activities of $1.2 million during the three months ended March 31, 2019 was primarily due to $19.2 million used to purchase investments and $1.6 million for capital expenditures partially offset by $19.6 million in maturities of marketable security investments.

Cash provided by investing activities of $11.1 million during the three months ended March 31, 2018 was primarily due to $13.9 million used to purchase investments and $0.6 million for capital expenditures, partially offset by $25.6 million in maturities of marketable security investments.

Cash Flows from Financing Activities

Cash provided by financing activities of $2.2 million during the three months ended March 31, 2019 was primarily due to $2.2 million received from the purchase of common stock through stock option exercises.

Cash used in financing activities of $1.9 million during the three months ended March 31, 2018 was primarily due to $3.5 million used to repurchase our common stock, partially offset by $1.6 million received from the purchase of common stock through stock option exercises.

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 fund investments in our latest technology arising from rapid market adoption that 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 research and development, manufacturing, and sales and marketing 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.

– 39 –

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.

Recent Accounting Pronouncements

There were no material accounting pronouncements adopted during the quarter ended March 31, 2019.

Item 3 — Quantitative and Qualitative Disclosures About Market Risk

Foreign Currency Risk

Our exposures are due to fluctuations in exchange rates for USD versus the British Pound, Saudi Riyal, United Arab Emirates Dirham, 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 U.S. Dollars (“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 cash equivalents 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 Risk and Credit Risk

We have an investment portfolio of fixed-income marketable debt securities, 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 the U.S. government and its agencies. These investments are subject to counterparty credit risk. To minimize this risk, we invest pursuant to a Board-approved investment policy. The policy mandates high credit rating requirements and restricts our exposure to any single corporate issuer by imposing concentration limits.

At March 31, 2019, all of our investments totaled approximately $74.3 million. These investments were presented in short-term investments and long-term investments on our Condensed Consolidated Balance Sheets as of March 31, 2019. 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 an average maturity of less than seven months. A hypothetical 1% increase in interest rates would have resulted in an approximately $0.3 million decrease in the fair value of our fixed-income debt securities as of March 31, 2019.

Item 4. — Controls and Procedures

(a) 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 the end of the period covered by this report, our disclosure controls and procedures are effective.

(b) 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.
