NOTE 1 – DESCRIPTION OF BUSINESS
 
ACM Research, Inc. (“ACM”) and its subsidiaries (collectively with ACM, the “Company”) develop, manufacture and sell single-wafer wet cleaning equipment used to improve the manufacturing process and yield for advanced integrated chips. The Company markets and sells its single-wafer wet-cleaning equipment, under the brand name “Ultra C,” based on the Company’s proprietary Space Alternated Phase Shift (“SAPS”) and Timely Energized Bubble Oscillation (“TEBO”) technologies. These tools are designed to remove random defects from a wafer surface efficiently, without damaging the wafer or its features, even at increasingly advanced process nodes.
 
ACM was incorporated in California in 1998, and it initially focused on developing tools for manufacturing process steps involving the integration of ultra low-K materials and copper. The Company’s early efforts focused on stress-free copper-polishing technology, and it sold tools based on that technology in the early 2000s.
 
In 2006 the Company established its operational center in Shanghai in the People’s Republic of China (the “PRC”), where it operates through ACM’s subsidiary ACM Research (Shanghai), Inc. (“ACM Shanghai”). ACM Shanghai was formed to help establish and build relationships with integrated circuit manufacturers in the PRC, and the Company initially financed its Shanghai operations in part through sales of non-controlling equity interests in ACM Shanghai.
 
In 2007 the Company began to focus its development efforts on single-wafer wet-cleaning solutions for the front-end chip fabrication process. The Company introduced its SAPS megasonic technology, which can be applied in wet wafer cleaning at numerous steps during the chip fabrication process, in 2009. It introduced its TEBO technology, which can be applied at numerous steps during the fabrication of small node two-dimensional conventional and three-dimensional patterned wafers, in March 2016. The Company has designed its equipment models for SAPS and TEBO solutions using a modular configuration that enables it to create a wet-cleaning tool meeting the specific requirements of a customer, while using pre-existing designs for chamber, electrical, chemical delivery and other modules. In August 2018, the Company introduced its Ultra-C Tahoe wafer cleaning tool, which can deliver high cleaning performance with significantly less sulfuric acid than typically consumed by conventional high-temperature single-wafer cleaning tools. The Company also offers a range of custom-made equipment, including cleaners, coaters and developers, to back-end wafer assembly and packaging factories, principally in the PRC.
 
In 2011 ACM Shanghai formed a wholly owned subsidiary in the PRC, ACM Research (Wuxi), Inc. (“ACM Wuxi”), to manage sales and service operations.
 
In June 2017 ACM formed a wholly owned subsidiary in Hong Kong, CleanChip Technologies Limited (“CleanChip”), to act on the Company’s behalf in Asian markets outside the PRC by, for example, serving as a trading partner between ACM Shanghai and its customers, procuring raw materials and components, performing sales and marketing activities, and making strategic investments.
 
In December 2017 ACM formed a wholly owned subsidiary in the Republic of Korea, ACM Research Korea CO., LTD. (“ACM Korea”), to serve customers based in Republic of Korea and perform sales, marketing, research and development activities for new products and solutions.
 
In March 2019 ACM Shanghai formed a wholly owned subsidiary in the PRC, Shengwei Research (Shanghai), Inc., to manage activities related to addition of future long-term production capacity.  The subsidiary was formed with registered capital of RMB 5,000 ($727).  As of March 31, 2020, $142 had been injected into this subsidiary.

In June 2019 Cleanchip formed a wholly owned subsidiary in California, ACM Research (CA), Inc.(“ACM California”), to provide procurement services on behalf of ACM Shanghai.
 
In June 2019 ACM announced plans to complete over the next three years a listing (the “Listing”) of shares of ACM Shanghai on the Shanghai Stock Exchange’s new Sci-Tech innovAtion boaRd, known as the STAR Market, and a concurrent initial public offering (the “STAR IPO”) of ACM Shanghai shares in the PRC. ACM Shanghai is currently ACM’s primary operating subsidiary, and at the time of announcement, was wholly owned by ACM. As an initial step in qualifying for the Listing and STAR IPO, in June 2019 ACM Shanghai entered into agreements with seven investors (the “First Tranche Investors”), pursuant to which the First Tranche Investors agreed to pay a purchase price totaling RMB 187,900 (equivalent to $27,300) to ACM Shanghai for shares representing 4.2% of the then-outstanding ACM Shanghai shares. In November 2019 ACM Shanghai entered into agreements with eight PRC-based investment firms (the “Second Tranche Investors”), pursuant to which the Second Tranche Investors agreed to acquire shares of ACM Shanghai for an aggregate of RMB 228,200 (equivalent to $32,400) for the same purchase price per share paid by the First Tranche Investors. Following the issuance of shares to the Second Tranche Investors, 91.7% of the outstanding shares of ACM Shanghai were owned by ACM, 3.8% were owned by the First Tranche Investors, and 4.5% were owned by the Second Tranche Investors. Because the First Tranche Investors and the Second Tranche Investors have the right to require ACM Shanghai to repurchase their ownership interests in ACM Shanghai at a fixed purchase price, those ownership interests are classified as redeemable non-controlling interests.

In preparation for the STAR IPO, ACM completed a reorganization in December 2019 that included the sale of all of the shares of Cleanchip by ACM to ACM Shanghai for $3,500. The reorganization and sale had no impact on ACM’s consolidated financial statements.

NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation and Principles of Consolidation
 
The Company’s consolidated financial statements include the accounts of ACM and its subsidiaries including ACM Shanghai and its subsidiaries, which include ACM Wuxi, ACM Shengwei, and CleanChip (the subsidiaries of which include ACM California and ACM Korea). ACM’s subsidiaries are those entities in which ACM, directly and indirectly, controls more than one half of the voting power. All significant intercompany transactions and balances have been eliminated upon consolidation.

The accompanying condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission for reporting on Form 10-Q. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements herein. The unaudited condensed consolidated financial statements herein should be read in conjunction with the historical consolidated financial statements of the Company for the year ended December 31, 2019 included in ACM’s Annual Report on Form 10-K for the year ended December 31, 2019.
 
ACM RESEARCH, INC.
Notes to Condensed Consolidated Financial Statements (unaudited)
(in thousands, except share and per share data)

The accompanying condensed consolidated balance sheet as of March 31, 2020, the condensed consolidated statements of operations and comprehensive income for the three months ended March 31, 2020 and 2019, the condensed consolidated statements of changes in stockholders’ equity for the three months ended March 31, 2020 and 2019, and the condensed consolidated statements of cash flows for the three months ended March 31, 2020 and 2019 are unaudited. In the opinion of management, the unaudited condensed consolidated financial statements of the Company reflect all adjustments that are necessary for a fair presentation of the Company’s financial position and results of operations. Such adjustments are of a normal recurring nature, unless otherwise noted. The balance sheet as of March 31, 2020 and the results of operations for the three months ended March 31, 2020 are not necessarily indicative of the results to be expected for any future period.
 
COVID-19 Assessment
 
The outbreak of COVID‑19, the coronavirus, has grown both in the United States and globally, and related government and private sector responsive actions have adversely affected the Company’s business operations. COVID‑19 originated in Wuhan, China, in December 2019, and a series of emergency quarantine measures taken by the PRC government disrupted domestic business activities in the PRC during the weeks after the initial outbreak of COVID‑19. Since that time, an increasing number of countries, including the United States, have imposed restrictions on travel to and from the PRC and elsewhere, as well as general movement restrictions, business closures and other measures imposed to slow the spread of COVID‑19. The situation continues to develop rapidly, however, and it is impossible to predict the effect and ultimate impact of the COVID‑19 outbreak on the Company’s business operations and results. While the quarantine, social distancing and other regulatory measures instituted or recommended in response to COVID‑19 are expected to be temporary, the duration of the business disruptions, and related financial impact, cannot be estimated at this time. The COVID‑19 outbreak has been declared a worldwide health pandemic that could adversely affect the economies and financial markets of many countries, resulting in an economic downturn and changes in global economic policy that could reduce demand for the Company’s products and its customers’ chips and have a material adverse impact on the Company’s business, operating results and financial condition.
 
Use of Estimates
 
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the balance sheet date and the reported revenue and expenses during the reported period in the condensed consolidated financial statements and accompanying notes. The Company’s significant accounting estimates and assumptions include, but are not limited to, those used for the valuation and recognition of stock-based compensation arrangements and warrant liability, realization of deferred tax assets, assessment for impairment of long-lived assets, allowance for doubtful accounts, inventory valuation for excess and obsolete inventories, lower of cost and market value or net realizable value of inventories, depreciable lives of property and equipment, and useful life of intangible assets. Management of the Company believes that the estimates, judgments and assumptions are reasonable, based on information available at the time they are made. Actual results could differ materially from those estimates.

ACM has been authorized to issue Class A and Class B common stock since redomesticating in Delaware in November 2016. The two classes of common stock are substantially identical in all material respects, except for voting rights. Since ACM did not declare any dividends during the three months ended March 31, 2020 and 2019, the net income per common share attributable to each class is the same under the “two-class” method. As such, the two classes of common stock have been presented on a combined basis in the condensed consolidated statements of operations and comprehensive income and in the above computation of net income per common share.
 
Diluted net income per common share reflects the potential dilution from securities that could share in ACM’s earnings. ACM’s potential dilutive securities consist of warrants and stock options for the three months ended March 31, 2020 and 2019.
 
Concentration of Credit Risk

The Company is potentially subject to concentrations of credit risks in its accounts receivable. For the three months ended March 31, 2020 and 2019, the Company’s three largest customers for the period accounted for 97.4% and 62.7% of revenue.  As of March 31, 2020 and December 31, 2019 the Company’s three largest customers accounted for 76.1% and 67.7% respectively, of the Company’s accounts receivables. The Company believes that the receivable balances from these largest customers do not represent a significant credit risk based on past collection experience.

Recent Accounting Pronouncements
 
Recently Adopted Accounting Pronouncements
 
In August 2018, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) 2018-13, Fair Value Measurement (Topic 820), which eliminates, adds and modifies certain disclosure requirements for fair value measurements. The modified standard eliminates the requirement to disclose changes in unrealized gains and losses included in earnings for recurring Level 3 fair value measurements and requires changes in unrealized gains and losses be included in other comprehensive income for recurring Level 3 fair value measurements of instruments. The standard also requires the disclosure of the range and weighted average used to develop significant unobservable inputs and how weighted average is calculate for recurring and nonrecurring Level 3 fair value measurements. The amendment is effective for fiscal years beginning after December 15, 2019 and interim periods within that fiscal year, with early adoption permitted. The adoption of ASU 2018-13 did not have a material impact on the Company’s consolidated financial statements.

Recent Accounting Pronouncements Not Yet Adopted
 
In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. ASU 2016-13 replaced the incurred loss impairment methodology under current GAAP with a methodology that reflects expected credit losses and requires consideration of a broader range of reasonable and supportable information to inform credit loss estimates. ASU 2016-13 requires use of a forward-looking expected credit loss model for accounts receivables, loans, and other financial instruments. ASU 2016-13 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. In October 2019, the FASB issued ASU 2019-10, Financial Instruments – Credit Losses (Topic 326), Derivatives and Hedging (Topic 815) and Leases (Topic 842), which defers the effective date for public filers that are considered small reporting companies as defined by the Securities and Exchange Commission to fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Since the Company is a smaller reporting company, implementation is not needed until January 1, 2023. Adoption of the standard requires using a modified retrospective approach through a cumulative-effect adjustment to retained earnings as of the effective date to align existing credit loss methodology with the new standard. The Company is evaluating the impact of this standard on its consolidated financial statements, including accounting policies, processes, and systems, and expects the standard will have a minor impact on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. ASU 2019-12 will simplify the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The amendments also improve consistent application of and simplify GAAP for other areas of Topic 740 by clarifying and amending existing guidance. For public business entities, the amendments in this ASU are effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2020. For all other entities, the amendments are effective for fiscal years beginning after December 15, 2021, and interim periods within fiscal years beginning after December 15, 2022. The Company is evaluating the impact of the adoption of ASU 2019-12, but does not expect it to have a material impact on income taxes as reported in its consolidated financial statements.

NOTE 8 –LEASES
 
The Company leases space under non-cancelable operating leases for several office and manufacturing locations. These leases do not have significant rent escalation holidays, concessions, leasehold improvement incentives, or other build-out clauses. Further, the leases do not contain contingent rent provisions.
 
Most leases include one or more options to renew. The exercise of lease renewal options is typically at the Company’s sole discretion; therefore, the majority of renewals to extend the lease terms are not included in the Company’s right-of-use assets and lease liabilities as they are not reasonably certain of exercise. The Company regularly evaluates the renewal options, and when they are reasonably certain of exercise, the Company includes the renewal period in its lease term.
 
As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at the lease commencement date in determining the present value of the lease payments. The Company has a centrally managed treasury function; therefore, based on the applicable lease terms and the current economic environment, it applies a portfolio approach for determining the incremental borrowing rate.

On December 9, 2016, Shengxin (Shanghai) Management Consulting Limited Partnership (“SMC”), a PRC limited partnership owned by employees of ACM Shanghai, including Jian Wang, the Chief Executive Officer and President of ACM Shanghai and the brother of David H. Wang (a related party), delivered RMB 20,124 ($2,981 as of the close of business on such date) in cash (the “SMC Investment”) to ACM Shanghai for potential investment pursuant to terms to be subsequently negotiated. On March 14, 2017, ACM, ACM Shanghai and SMC entered into a securities purchase agreement (the “SMC Agreement”) pursuant to which, in exchange for the SMC Investment, (a) ACM issued to SMC a warrant (the “SMC Warrant”) exercisable, for cash or on a cashless basis, to purchase, at any time on or before May 17, 2023, all, but not less than all, of 397,502 shares of Class A common stock at a price of $7.50 per share, for a total exercise price of $2,981 and (b) ACM Shanghai agreed to repay the SMC Investment within 60 days after exercise of the SMC Warrant. On March 30, 2018, SMC exercised the SMC Warrant in full and purchased 397,502 shares of Class A common stock (note 12). SMC borrowed the funds to pay the SMC Warrant exercise price pursuant to a senior secured promissory note in the principal amount of $2,981 issued to the Company (the “SMC Note”). The note bears interest at a rate of 3.01% per annum and matures on August 17, 2023 and is secured by a pledge of the shares issued upon exercise of the SMC Warrant. As described in the following paragraph, in the third quarter of 2019 ACM repurchased a total of 154,821 of the SMC Warrant shares from SMC at a per share price of $13.195, of which (a) $1,161 was applied to reduce SMC’s obligations to ACM Shanghai under the SMC Note and the remaining $882 was paid to SMC. In a separate transaction in August, 2019, ACM Shanghai repaid $1,161 of the SMC Investment in cash.

On August 14, 2019, ACM entered into an equity purchase agreement under which it agreed to repurchase, at a price per share of $13.195 (the net proceeds per share ACM received in a public offering of Class A common stock, as described in note 12), shares of Class A common stock from certain directors, employees and SMC upon the exercise of the underwriters’ over-allotment option in connection with the public offering in August 2019. The total consideration to the directors, employees and SMC, in exchange for their surrender of an aggregate of 214,286 shares of Class A common stock and cancellation of options to acquire 53,571 shares of Class A common stock amounted to a total of $3,403, which was based at a price of $13.195 per share equal to the net proceeds per share ACM received from the over-allotment option in connection with the offering.

NOTE 14– STOCK-BASED COMPENSATION
 
ACM’s stock-based compensation consists of employee and non-employee awards issued under the 1998 Stock Option Plan, the 2016 Omnibus Incentive Plan and as standalone options. In January 2020, ACM Shanghai, adopted a 2019 Stock Option Incentive Plan (the “Subsidiary Stock Option Plan”) which provides for, among other incentives, the granting to officers, directors, employees of ACM Shanghai options to purchase shares in ACM Shanghai’s common stock. The fair value of the stock options granted is estimated at the date of grant using the Black-Scholes option pricing model using assumptions generally consistent with those used for Company stock options. Because ACM Shanghai is not publicly traded, the expected volatility is estimated with reference to the average historical volatility of a group of publicly traded companies that are believed to have similar characteristics to ACM Shanghai.

NOTE 15 – INCOME TAXES
 
Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carry-forwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect of a change in tax rates on deferred tax assets and liabilities is recognized in income in the period during which such rates are enacted.

The Company considers all available evidence to determine whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become realizable. Management considers the scheduled reversal of deferred tax liabilities (including the impact of available carryback and carry-forward periods), and projected taxable income in assessing the realizability of deferred tax assets. In making such judgments, significant weight is given to evidence that can be objectively verified.

As of each reporting date, management considers new evidence, both positive and negative, that could affect its view of the future realization of deferred tax assets. Prior to September 30, 2019, the Company had recorded a valuation allowance for the full amount of net deferred tax assets in the United States, as the realization of deferred tax assets was uncertain.  Since September 30, 2019, the Company has not maintained a valuation allowance except for a partial valuation allowance on certain U.S. deferred tax assets.  In order to recognize the remaining U.S. deferred tax assets that continue to be subject to a valuation allowance, the Company will need to generate sufficient U.S. taxable income in future periods before the expiration of the deferred tax assets governed by the tax code.

ACM Shanghai has shown a three-year historical cumulative profit and has projections of future income. As a result, the Company maintained a partial consolidated valuation allowance for the three months ended March 31, 2020.

The Company accounts for uncertain tax positions in accordance with the authoritative guidance on income taxes under which the Company may only recognize or continue to recognize tax positions that meet a more likely than not threshold. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of the provision for income taxes.

(in thousands, except share and per share data)

The Company’s effective tax rate differs from statutory rates of 21% for U.S. federal income tax purposes and 15% to 25% for Chinese income tax purposes due to the effects of the valuation allowance and certain permanent differences from book-tax differences. As a result, the Company recorded income tax expense of $304 and $119 during the three months ended March 31, 2020 and 2019, respectively.

As of March 31, 2020, the Company’s total unrecognized tax benefits were $44, which would not affect the effective tax rate if recognized. The Company will recognize interest and penalties, when they occur, related to uncertain tax provisions as a component of tax expense. No interest or penalties were recognized for the three months ended March 31, 2020.

The Company files income tax returns in the United States, and state and foreign jurisdictions. The federal, state and foreign income tax returns are under the statute of limitations subject to tax examinations for the tax years ended December 31, 2009 through December 31, 2019. To the extent the Company has tax attribute carry-forwards, the tax years in which the attribute was generated may still be adjusted upon examination by the U.S. Internal Revenue Service, state or foreign tax authorities to the extent utilized in a future period.

Our effective tax rate differs from statutory rates of 21% for U.S. federal income tax purposes and 15% to 25% for Chinese income tax purposes due to the effects of the valuation allowance and certain permanent differences as it pertains to book-tax differences in the value of client equity securities received for services. Our two PRC subsidiaries, ACM Shanghai and ACM Wuxi, are liable for PRC corporate income taxes at the rates of 15% and 25%, respectively. Pursuant to the Corporate Income Tax Law of the PRC, ACM’s PRC subsidiaries generally would be liable for PRC corporate income taxes as a rate of 25%. According to Guoshuihan 2009 No. 203, an entity certified as an “advanced and new technology enterprise” is entitled to a preferential income tax rate of 15%. ACM Shanghai was certified as an “advanced and new technology enterprise” in 2012 and again in 2016 and 2018, with an effective period of three years.
 
We file income tax returns in the United States and state and foreign jurisdictions. Those federal, state and foreign income tax returns are under the statute of limitations subject to tax examinations for 2009 through 2016. To the extent we have tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by the Internal Revenue Service or state or foreign tax authorities to the extent utilized in a future period.

Management’s Discussion and Analysis of Financial Condition and Results of Operations
 
You should read the following discussion of our financial condition and results of operations together with our condensed consolidated financial statements and the related notes and other financial information included elsewhere in this report and our Annual Report on Form 10-K for the fiscal year ended December 31, 2019, or our Annual Report. The following discussion contains forward‑looking statements that reflect our plans, estimates, and beliefs. Our actual results could differ materially from those discussed in the forward‑looking statements. Factors that could cause or contribute to these differences include those discussed below and elsewhere in this report, particularly in the section titled “Item 1A. Risk Factors” in Part II below.
 
Overview
 
We supply advanced, innovative capital equipment developed for the global semiconductor industry. Fabricators of advanced integrated circuits, or chips, can use our single-wafer wet-cleaning tools in numerous steps to improve product yield, even at increasingly advanced process nodes. We have designed these tools for use in fabricating foundry, logic and memory chips, including dynamic random-access memory (or DRAM) and 3D NAND-flash memory chips. We also develop, manufacture and sell a range of advanced packaging tools to wafer assembly and packaging customers.
 
Selling prices for our single-wafer wet-cleaning tools range from $2 million to more than $5 million. Our customers for single-wafer wet-cleaning and other front-end cleaning tools have included Semiconductor Manufacturing International Corporation, Shanghai Huali Microelectronics Corporation, SK Hynix Inc. and Yangtze Memory Technologies Co., Ltd. We recognized revenue from sales of single-wafer wet cleaning and other front-end processing equipment totaling $22.8 million, or 94% of total revenue, for the three months ending March 31, 2020 compared to $12.8 million, or 63% of total revenue, for the three months ending March 31, 2019.
 
Based on Gartner’s December 2019 estimates, the market for global wafer cleaning equipment (auto wet stations, single-wafer processors, and other clean process) grew by 20% to $3.46 billion in 2018, decreased by 5% to $3.28 billion in 2019, and was expected to decrease by 6% to $3.07 billion in 2020.  We estimate, based on third-party reports and on customer and other information, that our tools address more than 50% of this global wafer cleaning equipment market.
 
We focus our selling efforts on establishing a referenceable base of leading foundry, logic and memory chip makers, whose use of our products can influence decisions by other manufacturers. We believe this customer base will help us penetrate the mature chip manufacturing markets and build credibility with additional industry leaders. Using a “demo-to-sales” process, we have placed evaluation equipment, or “first tools,” with a number of selected customers. Since 2009 we have delivered more than 95 single-wafer wet cleaning and other front-end processing tools, more than 85 of which have been accepted by customers and thereby generated revenue to us and the balance of which are awaiting customer acceptance should contractual conditions be met.
 
Since our formation in 1998, we have focused on building a strategic portfolio of intellectual property to support and protect our key innovations. Our tools have been developed using our key proprietary technologies:
Space Alternated Phase Shift, or SAPS, technology for flat and patterned wafer surfaces, which employs alternating phases of megasonic waves to deliver megasonic energy in a highly uniform manner on a microscopic level;
Timely Energized Bubble Oscillation, or TEBO, technology for patterned wafer surfaces at advanced process nodes, which provides effective, damage-free cleaning for 2D and 3D patterned wafers with fine feature sizes;
Tahoe technology for cost and environmental savings, which delivers high cleaning performance using significantly less sulfuric acid and hydrogen peroxide than is typically consumed by conventional high-temperature single-wafer cleaning tools; and
Electro-Chemical Plating, or ECP, technology for advanced metal plating, which includes Ultra ECP AP, or Advanced Packaging, technology for back-end assembly processes and Ultra ECP MAP, or Multi-Anode Partial Plating, technology for front-end wafer fabrication processes.

We conduct substantially all of our product development, manufacturing, support and services in the PRC. All of our tools are built to order at our manufacturing facilities in Shanghai, which encompass 86,000 square feet of floor space for production capacity.  In November 2019 ACM Shanghai entered into an agreement initiating a bidding process to acquire land rights to build a development and production center in the Lingang region of Shanghai. Our experience has shown that chip manufacturers in the PRC and throughout Asia demand equipment meeting their specific technical requirements and prefer building relationships with local suppliers. We will continue to seek to leverage our local presence to address the growing market for semiconductor manufacturing equipment in the region by working closely with regional chip manufacturers to understand their specific requirements, encourage them to adopt our SAPS, TEBO, Tahoe and ECP technologies, and enable us to design innovative products and solutions to address their needs.

We have been issued more than 285 patents in the United States, the People’s Republic of China or PRC, Japan, Korea, Singapore and Taiwan.
 
Corporate Background
 
ACM Research was incorporated in California in 1998 and redomesticated in Delaware in 2016. We perform strategic planning, marketing, and financial activities at our global corporate headquarters in Fremont, California.
 
Initially we focused on developing tools for chip manufacturing process steps involving the integration of ultra‑low‑K materials and copper. In the early 2000s we sold tools based on stress-free copper polishing technology. In 2007 we began to focus our development efforts on single-wafer wet-cleaning solutions for the front-end chip fabrication process. Since that time, we have strategically built our technology base and expanded our product offerings:
 
In 2009 we introduced SAPS megasonic technology, which can be applied in wet wafer cleaning at numerous steps during the chip fabrication process.
In 2016 we introduced TEBO technology, which can be applied at numerous steps during the fabrication of small node conventional two-dimensional and three-dimensional patterned wafers.
In August 2018 we introduced the Ultra-C Tahoe wafer cleaning tool, which delivers high cleaning performance with significantly less sulfuric acid than typically consumed by conventional high temperature single-wafer cleaning tools.
In March 2019 we introduced (a) the Ultra ECP AP or Advanced Wafer Level Packaging tool, a back-end assembly tool used for bumping, or applying copper, tin and nickel to wafers at the die-level prior to packaging, and (b) the Ultra ECP MAP or Multi Anode Plating tool, a front-end process tool that utilizes our proprietary technology to deliver world-class electrochemical copper planting for copper interconnect applications.
In April 2020 we introduced the Ultra Furnace, our first system developed for multiple dry processing applications.
In May 2020 we introduced the Ultra C Family of semi-critical cleaning systems, including the UltraC b for backside clean, the Ultra C wb automated wet bench, and the Ultra C s scrubber.
 
To help us establish and build relationships with chip manufacturers in the PRC, in 2006 we moved our operational center to Shanghai and began to conduct our business through our subsidiary ACM Shanghai. Since that time, we have expanded our geographic presence:
 
In 2011 ACM Shanghai formed a wholly owned subsidiary in the PRC, ACM Research (Wuxi), Inc., to manage sales and service operations.
In June 2017 we formed a wholly owned subsidiary in Hong Kong, CleanChip Technologies Limited, to act on our behalf in Asian markets outside the PRC by, for example, serving as a trading partner between ACM Shanghai and its customers, procuring raw materials and components, performing sales and marketing activities, and making strategic investments.
In December 2017 we formed a wholly owned subsidiary in the Republic of Korea, ACM Research Korea CO., LTD., to serve our customers based in the Republic of Korea and perform sales, marketing, and research and development activities.
 
We currently conduct the majority of our product development, support and services, and substantially all of our manufacturing at ACM Shanghai. Our Shanghai operations position us to be near many of our current and potential new customers in the PRC (including Taiwan), Korea and throughout Asia, providing convenient access and reduced shipping and manufacturing costs.
 
Our initial factory is located in the Pudong Region of Shanghai and has a total of 36,000 square feet of available floor space.
In September 2018 we announced the opening of a second factory in the Pudong region of Shanghai. The new facility has a total of 50,000 square feet of available floor space for production capacity.
In November 2019 ACM Shanghai entered into an agreement initiating a bidding process to acquire land rights to build a center in the Lingang region of Shanghai for manufacturing as well as development.
 
Recent Developments
 
STAR Market Listing and IPO
 
In June 2019, we announced our intention to complete:
a listing, which we refer to as the STAR Listing, of shares of ACM Shanghai on the Shanghai Stock Exchange’s Sci-Tech innovAtion boaRd, known as the STAR Market; and
a concurrent initial public offering, which we refer to as the STAR IPO, of ACM Shanghai shares in the People’s Republic of China, or the PRC, at a pre-offering valuation of not less than RMB 5.15 billion ($747.1 million).

We believe the listing of ACM Shanghai shares on the STAR Market will help us scale our business in mainland PRC, as we continue to seek to broaden our markets in Europe, Japan, Korea, Taiwan and the United States. Our global headquarters will continue to be located in Fremont, California, and we are committed to maintaining the listing of ACM Research Class A common stock on the Nasdaq Global Market.
 
To qualify for the STAR Listing, ACM Shanghai must have multiple independent stockholders in the PRC.
In June 2019 ACM Shanghai entered into agreements with seven investors, or the First Tranche Investors, pursuant to which the First Tranche Investors purchased ACM Shanghai shares for a total of RMB 187.9 million ($27.3 million as of June 12, 2019).
In November 2019 ACM Shanghai entered into agreements with each of the First Tranche Investors and eight PRC-based investment firms, or the Second Tranche Investors, pursuant to which the Second Tranche Investors subsequently purchased ACM Shanghai shares, or the Second Tranche Shares, for a total of RMB 228.2 million ($32.4 million as of November 29, 2019). The purchase price per Second Tranche Share was equal to the purchase price per share paid by the First Tranche Investors and was based on a pre-investment enterprise valuation of ACM Shanghai of RMB 4.84 billion ($688.9 million as of November 29, 2019).

As of March 31, 2020, 91.7% of the outstanding shares of ACM Shanghai were owned by ACM Research, 3.8% are owned by the First Tranche Investors and 4.5% are owned by the Second Tranche Investors. The board of directors of ACM Shanghai will consist of nine members, seven of whom will be nominated by ACM Research and two of whom will be nominated by two of the Second Tranche Investors.

If, within three years from the date on which ACM Shanghai shares were issued to the First Tranche Investors, the STAR Listing and the STAR IPO have not been completed and the China Securities Regulatory Commission has not otherwise approved the registration of ACM Shanghai’s listing application, each First Tranche Investor will have the right to require that ACM Shanghai repurchase, and ACM Shanghai will have the right to purchase, the First Tranche Investor’s ACM Shanghai shares for a price equal to the initial purchase price paid by the First Tranche Investor, without interest.

If ACM Shanghai does not officially submit application documents for the STAR Listing to the Shanghai Stock Exchange by December 31, 2022, each Second Tranche Investor will have the right to require that ACM Shanghai repurchase, and ACM Shanghai will have the right to require that each Second Tranche Investor sell to ACM Shanghai, such Second Tranche Investor’s Second Tranche Shares for a price equal to the initial purchase price paid by the Second Tranche Investor, without interest.

We have determined, voluntarily and not pursuant to any contractual or legal obligation, that pending either (a) ACM Shanghai’s submission of the application documents for the STAR Listing to the Shanghai Stock Exchange or (b) application to repurchase the Second Tranche Shares, ACM Shanghai will deposit, and hold in reserve, all of the proceeds received from the sale of Additional Placement Shares in segregated cash and cash-equivalent accounts.
 
Transactions Relating to SMC Investment

In December 2016 Shengxin (Shanghai) Management Consulting Limited Partnership, or SMC, paid 20,123,500 RMB ($3.0 million as of the date of funding), or the SMC Investment, to ACM Shanghai for investment pursuant to terms to be subsequently negotiated. SMC is a PRC limited partnership owned by employees of ACM Shanghai, including Jian Wang, the general partner of SMC. Jian Wang is the Chief Executive Officer and President of ACM Shanghai and the brother of David H. Wang, our Chief Executive Officer, President and Chair of the Board.

In March 2017, (a) ACM Research issued to SMC a warrant, or the Warrant, exercisable to purchase 397,502 shares of Class A common stock at a price of $7.50 per share, for a total exercise price of $3.0 million and (b) ACM Shanghai agreed to repay the SMC Investment within 60 days after the exercise of the Warrant.

In March 2018 SMC exercised the Warrant in full, as a result of which (1) ACM Research issued 397,502 shares of Class A common stock to SMC, (2) SMC borrowed the funds to pay the Warrant exercise price pursuant to a senior secured promissory note, or the SMC Note, in the principal amount of $3.0 million issued to ACM Shanghai, which in turn issued to ACM Research a promissory note, or the Intercompany Note, in the principal amount of $3.0 million in payment of the Warrant exercise price. Each of the two notes bears interest at a rate of 3.01% per annum and matures on August 17, 2023. The SMC Note was secured by a pledge of the shares issued upon exercise of the Warrant.

In connection with its follow-on public offering of Class A common stock in August 2019, ACM Research agreed to purchase a total of 154,821 of the Warrant shares from SMC at a per share price of $13.195, of which (a) $1.2 million was applied to reduce SMC’s obligations to ACM Shanghai under the SMC Note, and which ACM Research then withheld for its own account and applied to reduce ACM Shanghai’s obligations to ACM Research under the Intercompany Note and (b) the remaining $0.9 million was paid to SMC. In a separate transaction, ACM Shanghai repaid $1.2 million of the SMC Investment in cash, which reduced the amount of the SMC Investment due to SMC to $1.8 million.

In preparation for the STAR IPO, ACM Shanghai is required to terminate its financial relationship with SMC. In order to facilitate such termination, on April 30, 2020, ACM Research entered into two agreements relating to outstanding obligations among ACM Research, ACM Shanghai and SMC.  Pursuant to such agreements (i) ACM Shanghai assigned to ACM its rights under the SMC Note, including the right to receive payment of the $1.8 million payable thereunder; (ii) ACM Research cancelled the outstanding $1.8 million obligation of ACM Shanghai under the Intercompany Note, (iii) SMC transferred its remaining 242,681 Warrant shares to ACM Research, and (iv) in exchange for such 242,681 Warrant shares, ACM Research agreed to deliver to SMC certain consideration agreed upon by ACM Research and SMC, subject to obtaining certain PRC regulatory approvals. ACM Research and SMC agreed that if the required approvals are not obtained by December 31, 2023, ACM Research will cancel the SMC Note as consideration for the 242,681 Warrant shares.  In a separate transaction in April, 2020, ACM Shanghai repaid the remaining $1.8 million of the SMC Investment in cash.
 
COVID–19 Outbreak
 
COVID–19, or the coronavirus, originated in Wuhan, China, in December 2019 and has subsequently spread rapidly across the PRC and globally. The COVID–19 outbreak affected our business and operating results for the first quarter of 2020. The COVID–19 situation continues to develop rapidly, and it is impossible for us to predict the effect and ultimate impact of the COVID–19 outbreak on our business operations and results. While the quarantine, social distancing and other regulatory measures instituted or recommended in response to COVID–19 are expected to be temporary, the duration of the business disruptions, and related financial impact, of the outbreak cannot be estimated at this time. For an explanation of some of the risks we potentially face, please read carefully the information provided under “Item 1A. Risk Factors—Risks Related to the COVID–19 Outbreak,” which is incorporated by reference in “Item 1A. Risk Factors” of Part II of this report.

The following summary reflects our expectations and estimates based on information known to us as of the date of this filing:
 
Operations: We conduct substantially all of our product development, manufacturing, support and services in the PRC, and those activities have been directly impacted by the COVID–19 outbreak and related restrictions on transportation and public appearances. In February 2020 our ACM Shanghai headquarters were closed for an additional six days beyond the normal Lunar New Year Holiday in accordance with Shanghai government restrictions related to the outbreak. We took steps before and after the Lunar New Year to ensure no employees took unreasonable risks to rush back to work. Currently more than 95% of our staff have returned to work at both of our Shanghai facilities. To date we have not experienced absenteeism of management or other key employees, other than certain of our executive officers being delayed in traveling back to the PRC after working from our California office in February. Our corporate headquarters are located in Alameda County in the San Francisco Bay Area and are the subject of a number of state and county public health directives and orders. These actions have not negatively impacted our business to date, however, because of the limited number of employees at our headquarters and the nature of the work they generally perform.
 
Customers: Our customers’ business operations have been, and are continuing to be, subject to business interruptions arising from the COVID–19 outbreak. Historically a majority of our revenue from sales of single-wafer wet cleaning equipment for front-end manufacturing has been derived from customers located in the PRC and surrounding areas that have been impacted by COVID–19. Three customers that accounted for 73.8% of our revenue in 2019 and 87.6% of our revenue in 2018 are based in the PRC and Korea. One of those customers, Yangtze Memory Technologies Co., Ltd. — which accounted for 27.5% of our 2019 revenue and 39.6% of our 2018 revenue — is based in Wuhan. While Yangtze Memory Technologies Co., Ltd. and other key customers continued to operate their fabrication facilities without interruption during and after the first quarter of 2020, they were forced to restrict access of service personnel and deliveries to and from their facilities. A portion of the shipments we previously had expected to deliver in the first quarter of 2020 were postponed due in part to these factors. We believe these deliveries represent deferred, not lost, shipments and revenue, which we are working to recover by increasing our manufacturing output in the second and third quarters of 2020.
 
Suppliers: Our global supply chain includes components sourced from the PRC, Japan, Taiwan, the United States and Europe. While the COVID–19 outbreak has resulted in significant governmental measures being implemented to control the spread of COVID–19 around the world, to date we have not experienced material issues with our supply chain. As with our customers, we continue to be in close contact with our key suppliers to help ensure we are able to identify any potential supply issues that may arise.
 
Projects: Our strategy includes a number of plans to support the growth of our core business, including the proposed STAR Listing and STAR IPO with respect to shares of ACM Shanghai described above as well as ACM Shanghai’s proposed acquisition of land rights in the Lingang area of Shanghai where we intend to construct a new research and development center and factory. The extent to which COVID–19 impacts these projects will depend on future developments that are highly uncertain, but to date, the timing of these potential projects has not been delayed or disrupted by COVID–19 or related government measures.
 
Government Research and Development Funding
 
ACM Shanghai has received five special government grants from China’s Ministry of Science and Technology, the Shanghai Municipal Commission of Economy and Information, and the Shanghai Science and Technology Committee. The first grant, which was awarded in 2008, relates to the development and commercialization of 65nm to 45nm stress-free polishing technology. The second grant was awarded in 2009 to fund interest expense on short-term borrowings. The third grant was made in 2014 and relates to the development of electro copper-plating technology. The fourth grant was made in June 2018 and related to development of polytetrafluoroethylene. The fifth grant was made in 2020, and relates to the development of Tahoe single bench cleaning technologies. These governmental authorities provide the majority of the funding, although ACM Shanghai is also required to invest certain amounts in the projects.
 
The governmental grants contain certain operating conditions, and we are required to go through a government due diligence process once the project is complete. The grants therefore are recorded as long-term liabilities upon receipt, although we are not required to return any funds we receive. Grant amounts are recognized in our statements of operations and comprehensive income as follows:
 
Government subsidies relating to current expenses are reflected as reductions of those expenses in the periods in which they are reported. Those reductions totaled $0.2 million in the first three months of 2020, as compared to $1.3 million in the first three months of 2019.
Government grants used to acquire depreciable assets are transferred from long-term liabilities to property, plant and equipment when the assets are acquired and then the recorded amounts of the assets are credited to other income over the useful lives of the assets. Related government subsidies recognized as other income totaled $37,000 and $35,000 in the first three months of 2020 and 2019, respectively.
 
How We Evaluate Our Operations
 
We present information below with respect to four measures of financial performance:
 
We define “shipments” of tools to include (a)a “repeat” delivery to a customer of a type of tool that the customer has previously accepted, for which we recognize revenue upon delivery, and (b)a “first-time” delivery of a tool to a customer on an approval basis, for which we may recognize revenue in the future if contractual conditions are met and customer acceptance is received.
We define “adjusted EBITDA” as our net income excluding interest expense (net), income tax benefit (expense), depreciation and amortization, and stock-based compensation. We define adjusted EBITDA to also exclude restructuring costs, although we have not incurred any such costs to date.
We define “free cash flow” as net cash provided by operating activities less purchases of property and equipment (net of proceeds from disposals) and of intangible assets.
We define “adjusted operating income” as our income from operations excluding stock-based compensation.
 
These financial measures are not based on any standardized methodologies prescribed by accounting principles generally accepted in the United States, or GAAP, and are not necessarily comparable to similarly titled measures presented by other companies.
 
We have presented shipments, adjusted EBITDA, free cash flow and adjusted operating income because they are key measures used by our management and board of directors to understand and evaluate our operating performance, to establish budgets and to develop operational goals for managing our business. We believe that these financial measures help identify underlying trends in our business that could otherwise be masked by the effect of the expenses that we exclude. In particular, we believe that the exclusion of the expenses eliminated in calculating adjusted EBITDA and adjusted operating income can provide useful measures for period-to-period comparisons of our core operating performance and that the exclusion of property and equipment purchases from operating cash flow can provide a usual means to gauge our capability to generate cash. Accordingly, we believe that these financial measures provide useful information to investors and others in understanding and evaluating our operating results, enhancing the overall understanding of our past performance and future prospects, and allowing for greater transparency with respect to key financial metrics used by our management in its financial and operational decision-making.
 
Shipments, adjusted EBITDA, free cash flow and adjusted operating income are not prepared in accordance with GAAP, and should not be considered in isolation of, or as an alternative to, measures prepared in accordance with GAAP.
 
Shipments
 
Shipments consist of two components:
 
a shipment to a customer of a type of tool that the customer has previously-accepted, for which we recognize revenue when the tool is delivered; and
a shipment to a customer of a type of tool that the customer is receiving and evaluating for the first time, in each case a “first tool,” for which we may recognize revenue at a later date, subject to the customer’s acceptance of the tool upon the tool’s satisfaction of applicable contractual requirements.

“First tool” shipments can be made to either an existing customer that not previously accepted that specific type of tool in the past ─ for example, a delivery of SAPS V tool to a customer that previously had received only SAPS II tools ─ or to a new customer that has never purchased any tool from us.
 
Shipments in the three months ended March 31, 2020 totaled $12 million, as compared to $14 million in the three months ended March 31, 2019, and $25 million in the three months ended December 31, 2019.
 
The dollar amount attributed to a “first tool” shipment is equal to the consideration we expect to receive if any and all contractual requirements are satisfied and the customer accepts the tool. There are a number of limitations related to the use of shipments in evaluating our business, including that customers have significant discretion in determining whether to accept our tools and their decision not to accept delivered tools is likely to result in our inability to recognize revenue from the delivered tools.
 
Adjusted EBITDA
 
There are a number of limitations related to the use of adjusted EBITDA rather than net income, which is the nearest GAAP equivalent. Some of these limitations are:
 
adjusted EBITDA excludes depreciation and amortization and, although these are non-cash expenses, the assets being depreciated or amortized may have to be replaced in the future;
we exclude stock-based compensation expense from adjusted EBITDA and adjusted operating income, although (a) it has been, and will continue to be for the foreseeable future, a significant recurring expense for our business and an important part of our compensation strategy and (b) if we did not pay out a portion of our compensation in the form of stock-based compensation, the cash salary expense included in operating expenses would be higher, which would affect our cash position;
the expenses and other items that we exclude in our calculation of adjusted EBITDA may differ from the expenses and other items, if any, that other companies may exclude from adjusted EBITDA when they report their operating results;
adjusted EBITDA does not reflect changes in, or cash requirements for, working capital needs;
adjusted EBITDA does not reflect interest expense, or the requirements necessary to service interest or principal payments on debt;
adjusted EBITDA does not reflect income tax expense (benefit) or the cash requirements to pay taxes;
adjusted EBITDA does not reflect historical cash expenditures or future requirements for capital expenditures or contractual commitments;
although depreciation and amortization charges are non-cash charges, the assets being depreciated and amortized will often have to be replaced in the future, and adjusted EBITDA does not reflect any cash requirements for such replacements; and
adjusted EBITDA includes expense reductions and non-operating other income attributable to PRC governmental grants, which may mask the effect of underlying developments in net income, including trends in current expenses and interest expense, and free cash flow includes the PRC governmental grants, the amount and timing of which can be difficult to predict and are outside our control.
 
The following table reconciles net income, the most directly comparable GAAP financial measure, to adjusted EBITDA:

Adjusted EBITDA in the three months ended March 31, 2020, decreased by $97,000 as compared to the same period in 2019, due to an increase of $354,000 of interest income and a decrease of $55,000 in stock-based compensation expense, offset in part by an increase of $185,000 in income tax expense, an increase of $106,000 in net income and an increase of $21,000 in depreciation and amortization. We do not exclude from adjusted EBITDA expense reductions and non-operating other income attributable to PRC governmental grants because we consider and incorporate the expected amounts and timing of those grants in incurring expenses and capital expenditures. If we did not receive the grants, our cash expenses therefore would be lower, and our cash position would not be materially affected, to the extent we have accurately anticipated the amounts of the grants. For additional information regarding our PRC grants, please see “—Key Components of Results of Operations—PRC Government Research and Development Funding.”

Free Cash Flow

Free cash flow in the three months ended March 31, 2020, as compared to the same period in 2019, improved by $7 million, reflecting the factors driving net cash provided by operating activities, principally an increase in accounts payable, other long-term liabilities and inventory, offset by an increase in accounts receivable and other receivables. Consistent with our methodology for calculating adjusted EBITDA, we do not adjust free cash flow for the effects of PRC government subsidies, because we take those subsidies into account in incurring expenses and capital expenditures.
 
Adjusted Operating Income
 
Adjusted operating income excludes stock-based compensation from income from operations. Although stock-based compensation is an important aspect of the compensation of our employees and executives, determining the fair value of certain of the stock-based instruments we utilize involves a high degree of judgment and estimation and the expense recorded may bear little resemblance to the actual value realized upon the vesting or future exercise of the related stock-based awards. Furthermore, unlike cash compensation, the value of stock options, which is an element of our ongoing stock-based compensation expense, is determined using a complex formula that incorporates factors, such as market volatility, that are beyond our control. Management believes it is useful to exclude stock-based compensation in order to better understand the long-term performance of our core business and to facilitate comparison of our results to those of peer companies. The use of non-GAAP financial measures excluding stock-based compensation has limitations, however. If we did not pay out a portion of our compensation in the form of stock-based compensation, the cash salary expense included in operating expenses would be higher and our cash holdings would be less. The following tables reflect the exclusion of stock-based compensation, or SBC, from line items comprising income from operations:

Adjusted operating income for the three months ended on March 31, 2020, as compared with the same period in 2019 decreased by $1.1 million, due primarily to a $1.0 million decrease in income from operations and a $55,000 decrease in stock-based compensation expense.
 
Critical Accounting Policies and Significant Judgments and Estimates
 
There were no significant changes in our critical accounting policies or significant judgments or estimates during the three months ended March 31, 2020 to augment the critical accounting estimates disclosed under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report, other than those described in the notes to the condensed consolidated financial statements included in this report, including the adoption of the Financial Accounting Standards Board’s Accounting Standards Update 2016-02, Leases (Topic 842) effective January 1, 2019. As a result of our adoption of the new lease standard, we re-assessed the estimates, assumptions, and judgments that are most critical in our recognition of lease and have revised our lease critical accounting policy.  For information regarding the impact of recently adopted accounting standards, refer to note 2 to the condensed financial statements included in this report.
 
Recent Accounting Pronouncements
 
A discussion of recent accounting pronouncements is included in our Annual Report and is updated in note 2 to the condensed consolidated financial statements included in this report.

Cost of revenue increased $2.5 million and gross profit increased $1.4 million in the three months ended March 31, 2020, as compared to the corresponding period in 2019, due to increased sales volume and lower gross margin. Gross margin decreased by 1.1 percentage points during the three months ended March 31, 2020, versus the comparable period in 2019 due to differences in product mix.
 
Gross margin may vary from period to period, primarily related to the level of utilization and the timing and mix of purchase orders. We expect gross margin to be between 40.0% and 45.0% for the foreseeable future, with direct manufacturing costs approximating 50.0% to 55.0% of revenue and overhead costs totaling 5.0% of revenue.

Sales and marketing expense increased by $1.1 in the three months ended March 31, 2020, as compared to the corresponding period in 2019. Sales and marketing expense consists primarily of:
 
compensation of personnel associated with pre and aftersales support and other sales and marketing activities, including stock-based compensation;
sales commissions paid to independent sales representatives;
fees paid to sales consultants;
shipping and handling costs for transportation of products to customers;
cost of trade shows;
travel and entertainment; and
allocated overhead for rent and utilities.
 
Research and development expense increased by $0.9 million in the three months ended March 31, 2020 as compared to the corresponding period in 2019, principally as a result of increases in testing fees and personnel costs. Research and development expense represented 15.1% and 13.5% of our revenue in the three months ended March 31, 2020 and 2019, respectively. Without reduction by grant amounts received from PRC governmental authorities (see “—Key Components of Results of Operations—PRC Government Research and Development Funding”), gross research and development expense totaled $3.9 million, or 15.9% of revenue, in the three months ended March 31, 2020 and $4.1 million, or 20.0% of revenue, in the three months ended March 31, 2019. Research and development expense relates to the development of new products and processes and encompasses our research, development and customer support activities. Research and development expense consists primarily of:
 
compensation of personnel associated with our research and development activities, including stock based compensation;
costs of components and other research and development supplies;
travel expense associated with customer support;
amortization of costs of software used for research and development purposes; and
allocated overhead for rent and utilities.
 
General and administrative expense increased by $0.4 million in the three months ended March 31, 2020 as compared to the corresponding period in 2019. General and administrative expense consists primarily of:
 
compensation of executive, accounting and finance, human resources, information technology, and other administrative personnel, including stock-based compensation;
professional fees, including accounting and legal fees;
other corporate expenses; and
allocated overhead for rent and utilities.
 
We expect that, for the foreseeable future, general and administrative expenses will increase in absolute dollars, as we incur additional costs associated with growing our business and operating as a public company in the United States and in China.

Interest income consists of interest earned on our cash and equivalents and restricted cash accounts, offset by interest expense incurred from outstanding short-term borrowings. We earned $224,000 of interest income, net in the three months ended March 31, 2020 as compared to incurring ($130,000) of interest expense, net in the three months ended March 31, 2019.  This was a result of a larger balance of cash and equivalents and restricted cash along with reduced borrowings under short-term bank loans.
 
Other income (expense), net primarily reflects (a) gains or losses recognized from the impact of exchange rates on our foreign currency-denominated working-capital transactions and (b) depreciation of assets acquired with government subsidies, as described under “—Key Components of Results of Operations—PRC Government Research and Development Funding” above. Other income (expense), net was $677,000 in the three months ended March 31, 2020 due to primarily to gains and losses resulting from changes in the RMB-to-U.S. dollar exchange rate during the quarter, compared to Other income (expense), net of ($261,000) in the three months ended March 31, 2019 due to gains and losses resulting from changes in the RMB-to-U.S. dollar exchange rate during the quarter.

Our effective tax rate differs from statutory rates of 21% for U.S. federal income tax purposes and 15% to 25% for Chinese income tax purposes due to the effects of the valuation allowance and certain permanent differences as it pertains to book-tax differences in the value of client equity securities received for services. Our two PRC subsidiaries, ACM Shanghai and ACM Wuxi, are liable for PRC corporate income taxes at the rates of 15% and 25%, respectively. Pursuant to the Corporate Income Tax Law of the PRC, our PRC subsidiaries generally would be liable for PRC corporate income taxes as a rate of 25%. According to Guoshuihan 2009 No. 203, an entity certified as an “advanced and new technology enterprise” is entitled to a preferential income tax rate of 15%. ACM Shanghai was certified as an “advanced and new technology enterprise” in 2012 and again in 2016 and 2018, with an effective period of three years.
 
We file income tax returns in the United States and state and foreign jurisdictions. Those federal, state and foreign income tax returns are under the statute of limitations subject to tax examinations for 2009 through 2016. To the extent we have tax attribute carryforwards, the tax years in which the attribute was generated may still be adjusted upon examination by the Internal Revenue Service or state or foreign tax authorities to the extent utilized in a future period.
 
The Coronavirus Aid, Relief, and Economic Security Act (CARES Act) was enacted on March 27, 2020. It contains several provisions that may have financial statement effects. Key Aspects of the CARES Act include the following:

Repealed the 80% taxable income limitation for 2018, 2019 and 2020. Also allows those years to be carried back up to five years
Allows corporations to claim 100% of AMT credits in 2019.  It also provides for an election to take the entire refundable credit amount in 2018
Section 163(j) ATI limit raised from 30% to 50% for businesses
Technical corrections to TCJA for Qualified Improvement Property (“QIP”). Designates as 15-year property for depreciation purposes, which makes QIP a category eligible for 100% bonus depreciation
 
The CARES Act is not expected have a material impact on income taxes in the Company’s financial statements.
 
Net Income Attributable to Redeemable Non-Controlling Interests
 
As described above under “—STAR Market Listing and IPO,” in 2019, ACM Shanghai sold a total number of shares representing 8.3% of its outstanding ACM Shanghai shares. ACM Research continues to hold the remaining 91.7% of ACM Shanghai’s outstanding shares. As a result, commencing with the three months ended September 30, 2019, we reflect, as net income attributable to redeemable non-controlling interests, the portion of our net income allocable to the minority holders of ACM Shanghai shares. In the three months ended March 31, 2020, this amount totaled $258,000.
 
Liquidity and Capital Resources
 
During the first three months of 2020, we funded our technology development and operations principally through our beginning cash balance, application of net proceeds from a follow-on public offering of Class A common stock in 2019, short-term borrowings by ACM Shanghai from local financial institutions, and cash flow from operating activities.

We believe our existing cash and cash equivalents, our cash flow from operating activities, and short-term bank borrowings by ACM Shanghai will be sufficient to meet our anticipated cash needs for at least the next twelve months. We do not expect that our anticipated cash needs for the next twelve months will require our receipt of any PRC government subsidies. Our future working capital needs will depend on many factors, including the rate of our business and revenue growth, the payment schedules of our customers, and the timing of investment in our research and development as well as sales and marketing. To the extent our cash and cash equivalents, cash flow from operating activities and short-term bank borrowings are insufficient to fund our future activities in accordance with our strategic plan, we may determine to raise additional funds through public or private debt or equity financings or additional bank credit arrangements. We also may need to raise additional funds in the event we determine in the future to effect one or more acquisitions of businesses, technologies and products. If additional funding is necessary or desirable, we may not be able to obtain bank credit arrangements or to affect an equity or debt financing on terms acceptable to us or at all.

Sources of Funds

Cash Flow from Operating Activities. Our operations provided cash flow of $3.8 million in the first three months of 2020. Our cash flow from operating activities is influenced by (a) the level of net income, (b) the amount of cash we invest in personnel and technology development to support anticipated future growth in our business, (c) increases in the number of customers using our products, and (d) the amount and timing of payments by customers.

Equity and Equity-related securities. During the three months ended March 31, 2020, we received proceeds of $175,000 from sales of Class A common stock pursuant to option exercises.

Short-Term Loan Facilities. We have short-term borrowing with two banks, as follows:

Government Research and Development Grants. As described under “—Key Components of Results of Operations—PRC Government Research and Development Funding,” ACM Shanghai has received research and development grants from local and central PRC governmental authorities. ACM Shanghai received cash payments of $1.9 million related to such grants received in the three months ended March 31, 2020, as compared to cash payments of $22,000 related to such grants received during the same period in 2019. Not all grant amounts are received in the year in which a grant is awarded. Because of the nature and terms of the grants, the amounts and timing of payments under the grants are difficult to predict and vary from period to period. In addition, we expect to apply for additional grants when available in the future, but the grant application process can extend for a significant period of time and we cannot predict whether, or when, we will determine to apply for any such grants.

Working Capital. The following table sets forth selected working capital information:

Our cash and cash equivalents at March 31, 2020 were unrestricted and held for working capital purposes. ACM Shanghai, our only direct PRC subsidiary, is, however, subject to PRC restrictions on distributions to equity holders. We currently intend for ACM Shanghai to retain all available funds any future earnings for use in the operation of its business and do not anticipate its paying any cash dividends. We have not entered into, and do not expect to enter into, investments for trading or speculative purposes. Our accounts receivable balance fluctuates from period to period, which affects our cash flow from operating activities. Fluctuations vary depending on cash collections, client mix, and the timing of shipment and acceptance of our tools.

We have never declared or paid cash dividends on our capital stock. We intend to retain all available funds and any future earnings to support the operation of and to finance the growth and development of our business and do not anticipate paying any cash dividends in the foreseeable future.

Uses of Funds
 
Capital Expenditures. We incurred $0.1 million in capital expenditures in the first three months of 2020, versus $0.1 million during the same period in 2019.
 
Off-Balance Sheet Arrangements
 
As of March 31, 2020, we did not have any significant off-balance sheet arrangements, as defined in Item303 (a)(4)(ii) of Regulation S-K under the Securities Act of 1933.
 
Emerging Growth Company Status
 
We are an “emerging growth company” as defined in the Jumpstart Our Business Startups Act, or JOBS Act, and may take advantage of provisions that reduce our reporting and other obligations from those otherwise generally applicable to public companies. We may take advantage of these provisions until the earliest of December 31, 2022 or such time that we have annual revenue greater than $1.0 billion, the market value of our capital stock held by non-affiliates exceeds $700 million or we have issued more than $1.0 billion of non-convertible debt in a three-year period. We have chosen to take advantage of some of these provisions, and as a result we may not provide stockholders with all of the information that is provided by other public companies. We have, however, irrevocably elected not to avail ourselves, as would have been permitted by Section 107 of the JOBS Act, of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933 for complying with new or revised accounting standards, and we therefore will be subject to the same new or revised accounting standards as public companies that are not emerging growth companies
 
Item 3.
Quantitative and Qualitative Disclosures about Market Risks
 
We are a smaller reporting company as defined by Item 10(f)(1) of Regulation S-K under the Securities Act of 1933 and as such are not required to provide information under this Item.
 
Item 4.
Controls and Procedures
 
Disclosure Controls and Procedures
 
Our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures as of March 31, 2020. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the rules and forms of the Securities and Exchange Commission, or the SEC. Disclosure controls and procedures include controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Securities Exchange Act of 1934 is accumulated and communicated to the company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of March 31, 2020, our chief executive officer and chief financial officer concluded that, as of such date, our disclosure controls and procedures over financial reporting were effective.
 
Changes in Internal Control over Financial Reporting
 
During the three months ended March 31, 2020, no changes were identified to our internal control over financial reporting that materially affected, or were reasonably likely to materially affect, our internal control over financial reporting.
 
PART II. OTHER INFORMATION
 
Item 1.
Legal Proceedings
 
From time to time we may become involved in legal proceedings or may be subject to claims arising in the ordinary course of our business. Although the results of litigation and claims cannot be predicted with certainty, we currently believe that the final outcome of these ordinary course matters will not have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.
 
There have been no material developments with regard to legal proceedings in the three months ended March 31, 2020 or in the subsequent period up to the date of this report.
 
ITEM 1A.
RISK FACTORS
 
There were no material changes to the risk factors discussed in Item 1A, “Risk Factors” of Part I in our Annual Report.  In addition to the other information set forth in this report, you should carefully consider those risk factors, which could materially affect our business, financial condition and future operating results. Those risk factors are not the only risks facing our company. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may have a material adverse effect on our business, financial condition and operating results.
 
Item 2.
Unregistered Sales of Equity Securities and Use of Proceeds
 
Recent Sales of Unregistered Equity Securities
 
In the three months ended March 31, 2020, we issued and sold to employees and consultants an aggregate of 35,001 unregistered shares of Class A common stock upon the exercise of stock options at per share exercise prices between $0.75 and $1.50. These transactions did not involve any underwriters, any underwriting discounts or commissions, or any public offering. We believe the offers, sales and issuances of these shares were exempt from registration under the Securities Act of 1933 by virtue of Section 4(a)(2) thereof (or Regulation D promulgated thereunder) because the issuance of securities to the recipients did not involve a public offering or in reliance on Rule 701 under said Act because the transactions were pursuant to a contract relating to compensation as provided under such rule. The recipients of the shares represented their intentions to acquire the securities for investment only and not with a view to or for sale in connection with any distribution thereof, and appropriate legends were placed upon the shares issued in these transactions. The recipients had adequate access, through a relationship with us, to information about us. The sales of these shares were made without any general solicitation or advertising.
 
Use of Initial Public Offering Proceeds
 
The net proceeds of our initial public offering of Class A common stock in November 2017, after deducting underwriting discounts and commissions and offering expenses, were $17.3 million. There has been no material change in the planned use of proceeds from that described in the final prospectus filed with the SEC pursuant to Rule 424(b)(4) under the Securities Act of 1933 on November 3, 2017. To date we have applied the net proceeds to purchase inventory and ordinary course of business operations.
