NOTE 2 – SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
Basis of Presentation and Principles of Consolidation
The Company’s condensed consolidated financial statements include the accounts of ACM and its subsidiaries. ACM’s subsidiaries are those entities in which ACM, directly or indirectly, controls a majority 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 U.S. generally accepted accounting principles (“GAAP”) for interim financial information and the rules and regulations of the Securities and Exchange Commission (the “SEC”) for reporting on Form 10-Q. Accordingly, they do not include all the information and footnotes required by GAAP for complete financial statements. The accompanying condensed consolidated financial statements should be read in conjunction with the historical consolidated financial statements of the Company for the year ended December 31, 2025 included in ACM’s 2025 Annual Report on Form 10-K.
The accompanying condensed consolidated financial statements are unaudited. In the opinion of management, these 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 condensed consolidated balance sheet as of June 30, 2026 and the condensed consolidated results of operations for the three and six months ended June 30, 2026 are not necessarily indicative of the results to be expected for any future period.
Use of Estimates
The preparation of the 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 revenues 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 revenue recognition and deferred revenue, stock-based compensation arrangements, uncertain tax positions, warranty liabilities, allowance for credit losses, and inventory provision.
Management evaluates these estimates and assumptions on a regular basis. Actual results could differ from those estimates and assumptions.
Cash and Cash Equivalents

Cash and cash equivalents consist of cash on hand, bank deposits that are unrestricted as to withdrawal and use, and highly liquid investments with an original maturity date of three months or less at the date of purchase. At times, cash deposits may exceed government-insured limits.

The following table presents cash and cash equivalents, according to jurisdiction as of June 30, 2026 and December 31, 2025:

Cash held in the U.S. exceeds the Federal Deposit Insurance Corporation insurance limits and is subject to risk of loss. No losses have been experienced to date.
Cash amounts held in mainland China are subject to a series of risk control regulatory standards from mainland China bank regulatory authorities. ACM’s subsidiaries in mainland China are required to obtain approval from the State Administration of Foreign Exchange (“SAFE”) to transfer funds into or out of mainland China. SAFE requires a valid agreement to approve the transfers, which are processed through a bank. Other than these mainland China foreign exchange restrictions, ACM’s subsidiaries in mainland China are not subject to any restrictions and limitations on its ability to transfer funds to ACM or among our other subsidiaries. However, cash held in mainland China does exceed applicable insurance limits and is subject to risk of loss, although no such losses have been experienced to date.

ACM California periodically procures goods and services on behalf of ACM Shanghai. For these transactions, ACM Shanghai makes cash payments to ACM California in accordance with applicable transfer pricing arrangements. For the three months ended June 30, 2026 and 2025, cash payments from ACM Shanghai to ACM California for the procurement of goods and services was $191 and $3,509, respectively. For the six months ended June 30, 2026 and 2025, cash payments from ACM Shanghai to ACM California for the procurement of goods and services was $3,449 and $6,183, respectively. ACM California periodically borrows funds for working capital advances from its direct parent, CleanChip. ACM California repays or renews these intercompany loans in accordance with their terms.

For sales through CleanChip and ACM Research, a certain amount of sales or advance payments from customer proceeds is repatriated back to ACM Shanghai in accordance with applicable transfer pricing arrangements in the ordinary course of business. ACM Research provides support for tools under warranty to certain customers located in the U.S., Europe and other regions outside of mainland China on behalf of ACM Shanghai. For these transactions, ACM Shanghai makes cash payments to ACM Research in accordance with applicable transfer pricing arrangements.

Cash held in Hong Kong exceeds the Hong Kong Deposit Insurance Corporation insurance limits and is subject to risk of loss. No losses have been experienced to date. There are no additional restrictions for the transfer of cash from bank accounts in the U.S., South Korea, Singapore and Hong Kong.

For the six months ended June 30, 2026 and 2025, with the exception of sales and services-related transfer-pricing payments in the ordinary course of business, no transfers, or distributions have been made between ACM Research and its subsidiaries, including ACM Shanghai, or to holders of ACM Research Class A common stock.
Time Deposits

Time deposits are denominated in Chinese Renminbi (“RMB”) and U.S. dollars and deposited with banks in mainland China with fixed terms and interest rates and cannot be withdrawn before maturity. These deposits are presented as short-

ACM RESEARCH, INC.
Notes to the Condensed Consolidated Financial Statements
(In thousands, except share, percentage and per share data)
term deposits in the condensed consolidated financial statements based on their expected time of collection. They are also subject to the risk control regulatory standards described above upon maturity.

Time deposits held as of June 30, 2026 had interest rates of 1.2% to 3.91% and mature between November 2026 and June 2027.
Restricted Cash
All of the Company's restricted cash was held by financial institutions located in Mainland China, Hong Kong and South Korea, and mainly represents cash secured to guarantee delivery of tools.

Financial Instruments

The Company periodically invests in equity and debt securities, and maintains an investment portfolio of various holdings, types, and maturities. For equity investments that do not have a readily determinable fair value, the Company classifies them as long-term investments, and records them using either: 1) the measurement alternative which measures the equity investments at cost minus impairment, if any, plus or minus changes resulting from qualifying observable price changes; or 2) the equity method whereby the Company recognizes its proportional share of the income or loss from the equity method investment. For equity investments that have a readily determinable fair value, the Company classifies them as short-term investments, and records them at fair market value on a recurring basis based upon quoted market prices. Realized and unrealized gains resulting from application of the measurement alternative, the impact of the application of the equity method to the Company’s equity investments, and recognition of changes in fair market value, as applicable, are recorded in non-operating income or loss in the condensed consolidated statements of comprehensive income.

The Company’s investments in debt securities have been classified as available-for-sale securities. The Company classifies its debt securities as either short-term or long-term based on each instrument’s underlying contractual maturity date. Unrealized gains on debt securities classified as available-for-sale are recognized in accumulated other comprehensive income in the condensed consolidated balance sheets.
Fair Value Measurement

The Company’s fair value measurements and hierarchy are consistent with those disclosed in the Company’s Annual Report on Form 10‑K for the year ended December 31, 2025.

The Company’s financial instruments primarily include its cash, cash equivalents, restricted cash, short-term and long-term deposits, short-term and long-term investments, other receivables, accounts receivable, accounts payable, and short-term and long-term borrowings. The estimated fair value of cash and cash equivalents, restricted cash, short-term time deposits, accounts receivable, other receivables, accounts payable, and short-term borrowings approximate their respective carrying value due to the short period of time to their maturities.

All transfers between fair value hierarchy levels are recognized by the Company at the end of each reporting period. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, an investment’s level within the fair value hierarchy is based on the lowest level of input that is significant to the fair value measurement in its entirety, requires judgment and considers factors specific to the investment. The inputs or methodology used for valuing financial instruments are not necessarily an indication of the risks associated with investment in those instruments.

Assets measured at fair value on a recurring basis:

Basic$1.31 $0.47 $1.59 $0.79 
Diluted$1.23 $0.44 $1.49 $0.74 

ACM Research is authorized to issue Class A and Class B common stock. The two classes of common stock are substantially identical in all material respects, except for voting rights. The net income per share of common stock 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 comprehensive income and in the above computation of net income per share of common stock. ACM did not have any participating securities outstanding during the three and six months ended June 30, 2026 and 2025.

Diluted net income per share of common stock reflects the potential dilution from securities, such as stock options that could share in ACM Research’s earnings. Certain potentially dilutive securities were excluded from the net income per share calculation because the impact would be anti-dilutive. The number of potentially dilutive shares that were not included in the calculation of diluted net income per share in the periods presented where their inclusion would be anti-dilutive were stock options exercisable into shares of the Company’s common stock of 35,086 and 58,456 for the three and six months ended June 30, 2026, respectively and 1,338,186 and 1,321,311 for the three and six months ended June 30, 2025, respectively.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to credit risk consist principally of cash and cash equivalents, restricted cash, time deposits, and accounts receivable. The Company deposits and invests its cash with financial institutions that management believes are creditworthy.
The Company is potentially subject to concentrations of credit risks in its revenue and accounts receivable.

ACM RESEARCH, INC.
Notes to the Condensed Consolidated Financial Statements
(In thousands, except share, percentage and per share data)
Revenue concentration. For the three months ended June 30, 2026 and 2025, three customers accounted for 43.5% and four customers accounted for 66.5% of revenue, respectively. For the six months ended June 30, 2026 and 2025, one customer accounted for 12.7% and three customers accounted for 49.9% of revenue, respectively.
Accounts receivable concentration. As of June 30, 2026 and December 31, 2025, four customers accounted for 52.4% and four customers accounted for 62.2%, 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.
Recently issued accounting pronouncements not yet adopted

In December 2024, the FASB issued ASU 2024-03: Income Statement--Reporting Comprehensive Income--Expense Disaggregation Disclosures (Subtopic 220-40), which requires additional disclosures about specific types of expenses included in the expense captions presented on the face of the income statement as well as disclosures about selling expenses. In January 2025, the FASB issued ASU 2025-01, which clarifies the effective date of ASU 2024-03. ASU 2024-03 is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. This ASU should be applied prospectively with the option to apply the standard retrospectively. The Company is currently evaluating the provisions of this ASU.

In December 2025, the FASB issued ASU 2025-10 – Government Grants which establishes guidance on the recognition, measurement, and presentation of government grants received by business entities. The new guidance leverages the principles in the accounting framework for government assistance in International Accounting Standard 20 Accounting for Government Grants and Disclosure of Government Assistance. This ASU is effective for interim reporting periods within annual reporting periods beginning after December 15, 2028 and interim reporting periods within those annual periods. This ASU may be applied prospectively or retrospectively to any or all periods presented and early adoption of this ASU is permitted. The Company is currently evaluating the provisions of this ASU.

NOTE 13 – COMMON STOCK
ACM is authorized to issue 150,000,000 shares of Class A common stock and 5,307,816 shares of Class B common stock, each with a par value of $0.0001. Each share of Class A common stock is entitled to one vote, and each share of Class B common stock is entitled to twenty votes and is convertible at any time into one share of Class A common stock. Shares of Class A common stock and Class B common stock are treated equally, identically and ratably with respect to any dividends declared by the Board of Directors of ACM unless such Board of Directors declares different dividends to the Class A common stock and Class B common stock, which is subject to approval from a majority of common stockholders.
At June 30, 2026 and December 31, 2025, the number of shares of Class A common stock issued and outstanding was 64,651,365 and 60,590,017, respectively.
At June 30, 2026 and December 31, 2025, the number of shares of Class B common stock issued and outstanding was 4,991,808 and 5,021,811, respectively.
NOTE 14 – STOCK-BASED COMPENSATION

During the six months ended June 30, 2026, the Company issued option grants for 57,800 shares and restricted stock unit ("RSU") grants of 6,208 shares to employees under its 2016 Omnibus Incentive Plan. The share-based awards are accounted for as equity awards, are subject only to service vesting conditions, and vest over a period of 4 years for employees. The Company did not grant any non-employee stock options during the three and six months ended June 30, 2026 under the 2016 Omnibus Incentive Plan.

The fair value of options granted to employees is estimated on the grant date using the Black-Scholes valuation with following assumptions:
Six Months Ended June 30, 2026

(1)Fair value of Class A common stock value was closing market price of the Class A common stock on the grant date.
(2)Expected term of share options is based on the average of the vesting period and the contractual term for each grant.
(3)Volatility is calculated based on the historical volatility of ACM in the period equal to the expected term of each grant.
(4)Risk-free interest rate is based on the yields of U.S. Treasury securities with maturities similar to the expected term of the share options in effect at the time of grant.
(5) Expected dividend is assumed to be nil as ACM has no history or expectation of paying a dividend on its Class A common stock.

2026202520262025
Total income tax expense$(13,472)$(1,891)$(17,243)$(4,044)

The Company’s effective tax rate differs from the statutory rates of 21% for U.S. federal income tax purposes and 25% for Chinese income tax purposes primarily due to the effects of the valuation allowance and certain permanent book-tax differences, including stock-based compensation, Subpart F income, net CFC tested income (NCTI) inclusions, and the R&D super deduction. As a result, the Company recorded income tax expense of $17,243 and $4,044 for the six months ended June 30, 2026 and 2025, respectively. The increase in the Company's effective tax rate for the six months ended June 30, 2026 compared with the corresponding period in 2025 was primarily attributable to a higher estimated annual effective tax rate resulting from changes in the mix of earnings by jurisdiction and the relative impact of valuation allowances and permanent tax adjustments, partially offset by favorable discrete tax items recognized during 2026.

Under the changes to Section 174 enacted by the Tax Cuts and Jobs Act of 2017, which became effective on January 1, 2022, the Company is required to capitalize, and subsequently amortize R&D expenses over fifteen years for research activities conducted outside of the U.S. The capitalization of foreign R&D expenses results in an increase in the Company’s global intangible low-taxed income (“GILTI”) inclusion. The enactment of the One Big Beautiful Bill Act (“OBBBA”), signed into law in July 2025, repealed the mandatory capitalization requirement for domestic R&D expenses for tax years beginning after December 31, 2025. However, the capitalization requirement for research activities conducted outside of the U.S remains unchanged.

The Company had total unrecognized tax benefits of $20,905 as of June 30, 2026 and December 31, 2025. If recognized, the net impact on the Company’s effective tax rate would be approximately $20,770. The Company does not expect any significant changes in its unrecognized tax benefits within the next 12 months. The Company recognizes interest and penalties related to uncertain tax provisions as a component of income tax expense. For the six months ended June 30, 2026 and 2025, the Company recognized $905 and $807, respectively, of interest and penalties.

Pursuant to the Corporate Income Tax Law of mainland China, all of the Company’s mainland China subsidiaries are generally subject to mainland China Corporate Income Taxes at a statutory rate of 25%, except for ACM Shanghai and ACM Lingang, which qualify for preferential tax treatments. According to Guoshuihan 2009 No. 203, an entity certified as
24

ACM RESEARCH, INC.
Notes to the Condensed Consolidated Financial Statements
(In thousands, except share, percentage and per share data)
an “advanced and new technology enterprise” is entitled to a preferential income tax rate of 15%. ACM Shanghai has been certified as an “advanced and new technology enterprise” in 2012 and subsequently renewed its certification in 2016, 2018, 2021, and 2024. The current certification remains effective through December 31, 2026. ACM Lingang is eligible for preferential tax incentives that provide for an exemption from income tax during its first two profitable years following the utilization of net operating loss carryforwards, followed by a reduced tax rate equal to 50% of the statutory tax rate for the subsequent three years.
NOTE 16 – COMMITMENTS AND CONTINGENCIES
As of June 30, 2026, the Company had $780 of open capital commitments to construction contracts.
Covenants in ACM Lingang’s Grant Contract for State-owned Construction Land Use Right in Shanghai City (Category of R&D Headquarters and Industrial Projects), as amended, with the China (Shanghai) Pilot Free Trade Zone Lingang Special Area Administration require, among other things, that ACM Lingang pay liquidated damages in the event that, by December 12, 2029, the Company does not (i) generate a minimum specified amount of annual sales of products manufactured on the granted land or (ii) pay to mainland China at least 80% of RMB157.60 million ($22.8 million) in annual total taxes (including value-added taxes, corporate income tax, personal income taxes, urban maintenance and construction taxes, education surcharges, stamp taxes, and vehicle and shipping taxes) as a result of operations in connection with the granted land.
Legal Matters
In the normal course of business, the Company is subject to contingencies, including legal proceedings, investigations, and environmental claims arising out of the normal course of business that relate to a wide range of matters, including among others, contracts breach liability. The Company records accruals for such contingencies based upon the assessment of the probability of occurrence and, where determinable, an estimate of the liability. Management may consider many factors in making these assessments including past history, scientific evidence and the specifics of each matter. Some of these contingencies involve claims that are subject to substantial uncertainties and un-estimable damages.

The Company’s management has evaluated all proceedings and claims that existed as of June 30, 2026. In the opinion of management, no additional provision for liability nor disclosure was required as of June 30, 2026 related to any claim against the Company because: (a) there is not a reasonable possibility that a loss exceeding amounts already recognized (if any) may be incurred with respect to such claim; (b) a reasonably possible loss or range of loss cannot be estimated; or (c) such estimate is immaterial.
As of June 30, 2026, the Company had no material outstanding legal proceedings.
NOTE 17 – SEGMENT INFORMATION

The Company identifies operating segments according to how the business activities are managed and evaluated. The Company’s chief operating decision maker (“CODM”) has been identified as ACM’s Chief Executive Officer. The Company's operating segments include ACM Research and ACM Shanghai. As the Company is engaged in the development, manufacture and sale of capital equipment to global semiconductor manufacturers, and each of the operating segments share similar economic and other qualitative characteristics, the results of the Company’s operating segments are aggregated into one reportable segment.

The CODM assesses financial performance for the Company and decides how to allocate resources based on consolidated revenue, gross margin and income from operations. The CODM considers forecasts and actual results on a regular basis when assessing the operating results and making resource decisions.

Significant expenses within income from operations, as well as within net income, include consolidated cost of revenue, sales and marketing, research and development, and general and administrative, and which are each separately presented on the Company’s condensed consolidated statements of comprehensive income. Other segment items within net income include interest income, interest expense, income from equity method investments and other expense, net, which are each

Item 2.    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, 2025, or our 2025 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 in Part I, Item 1A. “Risk Factors” in our 2025 Annual Report, as well as those discussed below and elsewhere in this report, particularly in the section titled “Item 1A – Risk Factors” in Part II below.

ACM Research, Inc., or ACM Research, is a Delaware corporation founded in California in 1998 to supply capital equipment developed for the global semiconductor industry. Since 2005, ACM Research has conducted its business operations principally through its subsidiary ACM Research (Shanghai), Inc., or ACM Shanghai, a corporation formed by ACM Research in the People’s Republic of China, or mainland China, in 2005. Unless the context requires otherwise, references in this report to “our company,” “our,” “us,” “we” and similar terms refer to ACM Research, Inc. and its subsidiaries, including ACM Shanghai, collectively.

Our principal corporate office is located in Fremont, California. We conduct a substantial majority of our product development, manufacturing, support and services in mainland China through ACM Shanghai. We perform, through a subsidiary of ACM Shanghai, additional product development and subsystem production in Korea, and we conduct, through ACM Research, sales and marketing activities focused on sales of ACM Shanghai products in North America, Europe and certain regions in Asia outside mainland China.

ACM Research is not a mainland China operating company, and we do not conduct our operations in mainland China through the use of a variable interest entity, or VIE, or any other structure designed for the purpose of avoiding mainland China legal restrictions on direct foreign investments in mainland China-based companies. ACM Research has a direct ownership interest in ACM Shanghai as the result of its holding 73.2% of the outstanding shares of ACM Shanghai. Stockholders of ACM Research may never directly own equity interests in ACM Shanghai. We do not believe that our corporate structure or any other matters relating to our business operations require that we obtain any permissions or approvals from the China Securities Regulatory Commission, the Cyberspace Administration of China, or any other mainland China central government authority in order to continue to list shares of Class A common stock of ACM Research on the Nasdaq Global Select Market. This determination was based on the facts aforementioned and mainland China Company Law, mainland China Securities Law, cybersecurity regulations and other relevant laws, regulations and regulatory requirements in mainland China currently in effect. However, if this determination proves to be incorrect, then it could have a material adverse effect on ACM Research. See “Item IA. Risk Factors—Risks Related to International Aspects of Our Business—If any mainland China central government authority were to determine that existing mainland China laws or regulations require that ACM Shanghai obtain the authority’s permission or approval to continue the listing of ACM Research’s Class A common stock in the United States or if those existing mainland China laws and regulations, or interpretations thereof, were to change to require such permission or approval, ACM Shanghai may be unable to obtain the required permission or approval or may only be able to obtain such permission or approval on terms and conditions that impose material new restrictions and limitations on operation of ACM Shanghai, either of which could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects and on the trading price of ACM Research Class A common stock, which could decline in value or become worthless” in our 2025 Annual Report.

In addition, in the ordinary course of business, ACM Shanghai is required to obtain certain operating permits and licenses necessary for it to operate in mainland China, including business licenses, certifications relating to quality management standards, import and export-related qualifications from customs, as well as environmental and construction permits, licenses and approvals relating to construction projects. We believe ACM Shanghai has all such required permits and licenses. However, from time to time mainland China government issues new regulations, which may require additional actions on the part of ACM Shanghai to comply. If ACM Shanghai does not, or is unable to, obtain any such additional permits or licenses, ACM Shanghai may be subjected to restrictions and penalties imposed by the relevant mainland China regulatory authorities, and it could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects and on the trading price of ACM Research Class A common stock, which could decline in value or become worthless.

On February 6, 2026, ACM completed the sale of approximately 4.8 million shares of ACM Shanghai at a price of RMB160.00 per share (approximately $23.05 per share based on the exchange rate in effect on the date of the sale), generating approximately $110.2 million in gross proceeds and approximately $86 million net of taxes.
27

On May 12, 2026, ACM Shanghai's employees exercised 2,431,900 options for shares of ACM Shanghai stock. Following this transactions, ACM’s ownership percentage in ACM Shanghai decreased from 73.6% as of March 31, 2025 to 73.2% as of June 30, 2026.
The following chart depicts our corporate organization as of June 30, 2026:
organization chart - Q2 2026 (1).gif
A detailed description of how cash is transferred through our organization is set forth under “Note 2 – Summary of Significant Accounting Policies – Cash and Cash Equivalents” to the Condensed Consolidated Financial Statements of this report.

The U.S. Holding Foreign Companies Accountable Act, or the HFCA Act, requires that the Public Company Accounting Oversight Board, or the PCAOB, determine whether it is unable to inspect or investigate completely registered public accounting firms located in a non-U.S. jurisdiction because of a position taken by one or more authorities in any non-U.S. jurisdiction. Under current regulations, if ACM Research were to be included on the SEC's "Conclusive list of issuers identified under the HFCA Act" for two consecutive years due to our independent auditor being located in a jurisdiction that does not allow for PCAOB inspections, the SEC would prohibit trading in our securities and this ultimately could cause our securities to be delisted in the U.S., and their value may significantly decline or become worthless. See “Item 1A. Risk Factors—Risks Related to International Aspects of Our Business—We could be adversely affected if we are unable to comply with legislation and regulations regarding improved access to audit and other information and audit inspections of accounting firms, including registered public accounting firms, such as our prior and current audit firms, operating in mainland China” in our 2025 Annual Report for more information.

Effective on December 2, 2024, the U.S. Department of Commerce’s Bureau of Industry and Security (“BIS”) promulgated a final rule naming a number of companies to the BIS Entity List (the "BIS Entity List"). Among the 140 companies added to the BIS Entity List were two subsidiaries of ACM Research, ACM Shanghai, located in the People’s Republic of China, and ACM Korea, a direct subsidiary of ACM Shanghai, which is located in the Republic of Korea, and other related entities. In general terms, the new BIS Entity List designations prohibit any party worldwide from furnishing hardware, software, or technologies that are subject to U.S. export controls jurisdiction, directly or indirectly to ACM Shanghai or ACM Korea without obtaining authorization. See “Item 1A. Risk Factors—Regulatory Risks—Our operations in mainland China and Korea, including the import of components, technology, and activities of U.S. personnel therein, may be further impacted by the addition of ACM Shanghai, ACM Korea and related entities to the BIS Entity List” in our 2025 Annual Report for more information.

On November 15, 2024, the U.S. Department of the Treasury published a final rule implementing a framework for the regulation of outbound foreign investment from the United States. The new program, known as the Outbound Investment Security Program (“OISP”) was codified in the United States Code of Federal Regulations at 31 C.F.R. Part 850, effective as of January 2, 2025. The OISP was amended by the Comprehensive Outbound Investment National Security Act (“COINS Act”) which was signed into law on December 18, 2025, although the provisions of the COINS Act will not come into effect until the Department of the Treasury issues implementing regulations, which by law must occur by March 2027. The OISP marks a shift in U.S. economic policy, as historically the United States government declined to restrict outbound investment from the United States for national security reasons. Going forward, the investment activities of multinational companies, including ACM Research are subject to both CFIUS and OISP requirements, which together will limit cross-border investment opportunities, especially as they relate to China. The OISP regulations in effect today could
28

be interpreted to restrict certain types of private investment in ACM Research in the United States, although these measures do not impact investment in ACM Research’s publicly traded securities. The COINS Act reverses the possible application of the OISP to certain U.S. companies, including ACM Research, and therefore it appears ACM Research will not be subject to the OISP’s private investment restrictions once the provisions of the COINS Act enter into force in 2026 or 2027. See “Item 1A. Risk Factors—Regulatory Risks—The U.S. Government has implemented an outbound investment review mechanism, which may prevent us from taking advantage of investment opportunities hat could otherwise be advantageous to our stockholders” in our 2025 Annual Report for more information.

In addition to the matters discussed above, we are also subject to a number of legal and operational risks associated with our corporate structure, including, as the result of a substantial portion of our operations being conducted in mainland China. Consequences of any of those risks could result in a material adverse change in our operations or cause the value of ACM Research Class A common stock to significantly decline in value or become worthless. Please carefully read the information included in “Item 1A. Risk Factors” in our 2025 Annual Report, in particular, the risk factors addressing the following issues:

• If any mainland China central government authority were to determine that existing mainland China laws or regulations require that ACM Shanghai obtain the authority’s permission or approval to continue the listing of ACM Research’s Class A common stock in the United States or if those existing mainland China laws and regulations, or interpretations thereof, were to change to require such permission or approval, or if we inadvertently conclude that such permissions or approvals are not required, ACM Shanghai may be unable to obtain the required permission or approval or may only be able to obtain such permission or approval on terms and conditions that impose material new restrictions and limitations on operation of ACM Shanghai, either of which could have a material adverse effect on our business, financial condition, results of operations, reputation and prospects and on the trading price of ACM Research Class A common stock, which could decline in value or become worthless.
Mainland China central government authorities may intervene in, or influence, ACM Shanghai’s mainland China-based operations at any time, and those authorities’ rules and regulations in mainland China can change quickly with little or no advance notice.
The mainland China central government may determine to exert additional control over offerings conducted overseas or foreign investment in mainland China-based issuers, which could result in a material change in operations of ACM Shanghai and cause significant declines in the value of ACM Research Class A common stock, or make them worthless.

Recent statements and regulatory actions by mainland China central government authorities with respect to the use of VIEs and to data security and anti-monopoly concerns have not affected our ability to conduct our business operations in China. For further information, see “Item 1A. Risk Factors —Risks Related to International Aspects of Our Business” of our 2025 Annual Report for more information.

Overview

We supply advanced, innovative capital equipment developed for the global semiconductor industry. Fabricators of advanced integrated circuits, or chips, can use our wet-cleaning and other front-end processing 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.

Since 2009 we have delivered more than 1,590 tools to our customers, more than 1,430 of which were repeat orders or acceptances upon contractual performance obligations that have been met and thereby generated revenue to us. The balance of the delivered tools is subject to the customer's acceptance of the tool upon the tool's satisfaction of applicable contractual requirements or subject to the customer's subsequent discretionary commitment to purchase the tool. To date, substantially all of our sales of equipment for semiconductor-manufacturing have been to customers located in Asia, and we anticipate that a substantial majority of our revenue from these products will continue to come from customers located in this region for the foreseeable future. We have begun to add to our efforts to further address customers in North America, Western Europe and Southeast Asia, by expanding our direct sales teams and increasing our global marketing activities.

We estimate, based on third-party reports, customer feedback and other information, that our current product portfolio addresses approximately $22 billion of the 2025 global wafer fab equipment, or WFE, market. By product line, we estimate an approximately $7.4 billion market opportunity is addressed by our wafer cleaning equipment, $6.2 billion by our
29

Plasma-Enhanced Chemical Vapor Deposition, or PECVD, equipment, $3.5 billion by our Track equipment, $1.7 billion by our furnace equipment, $1.8 billion by our electro-chemical plating, or ECP, equipment, and $1.5 billion by our stress-free polishing, advanced packaging, wafer processing, and other processing equipment.
Frost & Sullivan estimates the total worldwide semiconductor equipment market grew by 16.3% from $122.2 billion in 2024 to $142.1 billion in 2025, and is expected to increase by 7.3% to $152.5 billion in 2026. Frost & Sullivan estimates the China semiconductor equipment market increased by 11.8%, from $46.8 billion in 2024 to $52.3 billion in 2025, and is expected to increase by 10.1% to $57.6 billion in 20261.
Recent Developments
ACM Registered Direct Offering

On May 12, 2026, we entered into a Securities Purchase Agreement (the “Securities Purchase Agreement”) with certain U.S. institutional investors named therein managed by Tekne Capital Management, LLC (the “Investors”). Pursuant to the Securities Purchase Agreement, we agreed to issue and sell to the Investors in a registered direct offering (the “Direct Offering”) an aggregate of 2,884,615 shares (the “Direct Offering Shares”) of our Class A common stock at an offering price of $52.00 per Direct Offering Share pursuant to an effective shelf registration statement on Form S-3 (File No. 333-278041) and a related prospectus supplement filed with the SEC on May 12, 2026. The transaction closed on May 15, 2026 and generated proceeds of approximately $148.4 million, net of issuance costs.
ACM Shanghai Proposed IPO listing on The Stock Exchange of Hong Kong Limited
On May 26, 2026, ACM Shanghai issued an announcement (the “Announcement”) to the SSE regarding the Resolutions of the Fifth Meeting of the Third Board of Directors. At the meeting, the board of directors of ACM Shanghai approved, among other matters, the proposal on the offering of H shares and listing on the Main Board of The Stock Exchange of Hong Kong Limited (the “H Share Listing”) and, on an item-by-item basis, the proposal on the plan for the H Share Listing. These proposals have been approved by ACM Shanghai’s board of directors and remain subject to approval by its shareholders. Pursuant to the approved plan, ACM Shanghai proposes to issue H shares representing no more than 7% of its total issued share capital upon completion of the proposed offering (prior to the exercise of any over-allotment option), and may grant the overall coordinators an over-allotment option to purchase up to 15% of the number of H shares initially offered. The H shares to be issued will be ordinary shares of H share class, with a par value of RMB 1.00 per share, to be listed and traded on the Main Board of The Stock Exchange of Hong Kong Limited. Net proceeds from the proposed H Share Listing, after deduction of offering expenses, are intended to be used for purposes including, but not limited to, further product development and enhancement of independent research and development capabilities, improvement of global market expansion and service capabilities, replenishment of general working capital and repayment of bank loans. The proposed H Share Listing remains subject to market conditions and the obtaining of necessary filings, approvals and/or other regulatory clearances, including those from the China Securities Regulatory Commission, The Stock Exchange of Hong Kong Limited and the Securities and Futures Commission of Hong Kong.
ACM Shanghai Facility Purchase
On June 5, 2026, we purchased a facility consisting of 3,196-square-meters of general-purpose office space located in Shanghai’s Pudong New Area for RMB 312.7 million ($45.9 million). To partially finance the purchase, we entered into a loan agreement with the Bank of China in the loan amount of RMB 231.5 million ($34.0 million) at a 2.65% interest rate, with a repayment term of 120 months. The facility was subsequently pledged as security for loan from the Bank of China in July 2026.
Mainland China Government Research and Development Funding
Since 2008, ACM Shanghai has received various government grants for the development and commercialization of certain technologies, and the development of the R&D and production center in the Lingang Special Area of Shanghai.

The governmental grants contain certain operating conditions, and we are required to complete 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 received by ACM Shanghai.

Grant amounts are recognized in our condensed consolidated statements of comprehensive income as follows:
Government subsidies relating to current expenses are recorded as reductions of those expenses in the periods in which the current expenses are recorded. Such subsidies included in our condensed consolidated statements of comprehensive income were both $0.5 million, in each of the three months ended June 30, 2026 and 2025, respectively, and $1.1 million and $0.8 million in the six months ended June 30, 2026 and 2025, respectively.
Government subsidies related to depreciable assets are credited to income over the useful lives of the related assets for which the grant was received. Government subsidies related to VAT reduction are credited to income in the period received. Such subsidies included in our condensed consolidated statements of comprehensive income were $1.2 million and $0.4 million, in the three months ended June 30, 2026 and 2025, respectively, and $1.4 million and $0.7 million in the six months ended June 30, 2026 and 2025, respectively.
Recent Accounting Pronouncements

A discussion of recent accounting pronouncements is included in our 2025 Annual Report and is updated in Note 2 to the condensed consolidated financial statements included in this report.
Net Income Attributable to Non-Controlling Interests

Net income attributable to non-controlling interests is attributable to the minority holders of shares of ACM Shanghai stock. As a result, we reflect the portion of our net income allocable to the minority holders of ACM Shanghai shares as net income attributable to non-controlling interests. As of June 30, 2026, ACM Research held 73.2% of ACM Shanghai’s outstanding shares.
Critical Accounting Policies and Estimates

In preparing our condensed consolidated financial statements in conformity with GAAP, we make assumptions, judgments and estimates in applying our accounting policies that can have a significant impact on our revenue, operating income and net income, as well as on the value of certain assets and liabilities on our condensed consolidated balance sheets. We base our assumptions, judgments and estimates on historical experience and various other factors that we believe to be reasonable under the circumstances. At least quarterly, we evaluate our assumptions, judgments and estimates and make changes as deemed necessary. Actual results could differ materially from these estimates under different assumptions or conditions.

We believe that the assumptions, judgments and estimates involved in the accounting for the following accounting policies have the greatest potential impact on our condensed consolidated financial statements, and we therefore consider these to be our critical accounting estimates. For information on our significant accounting policies, see Note 2 in the notes to condensed consolidated financial statements in Part I, Item 1 of this report and in the Notes to Condensed Consolidated Financial Statements in Part II, Item 8 of our 2025 Annual Report, describe the significant accounting policies and methods used in the preparation of the Company’s condensed consolidated financial statements. There have been no material changes to the Company’s critical accounting estimates included in our 2025 Annual Report.

The increase in revenue for three months ended June 30, 2026 as compared to the same period in 2025 reflects higher sales of ECP (front-end and packaging), furnace and other technologies, and Advanced packaging (excluding ECP), services and
32

spares, partially offset by lower sales of single wafer cleaning, Tahoe and semi-critical cleaning equipment. We attribute the increase to a longer-term commitment by our mainland China-based customers to increase production capacity to achieve a greater share of the global semiconductor market together with the market share changes and product cycles.

Gross margin46.0 %48.5 %(5.2)%(255) bps

Cost of revenue and gross profit increased due to the increased sales volume together with a decrease in gross margin. The decrease in gross margin versus the prior-year period was primarily due to revenue mix between product categories. Gross margin may vary from period to period, primarily related to the level of utilization and the timing and mix of revenue. We expect gross margin to be between 42.0% and 48.0% for the foreseeable future.

Total operating expenses$84,875 $72,767 16.6 %$12,108 

Sales and marketing expense increased due to a $1.5 million increase in commissions, professional services, and other expenses, and a $1.0 million increase in personnel costs, offset by a $0.8 million decrease in stock-based compensation. We expect that, for the foreseeable future, sales and marketing expense will increase in absolute dollars, as we continue to invest in sales and marketing by hiring additional employees and expanding marketing programs in existing or new markets. We must invest in sales and marketing processes to develop and maintain close relationships with customers. We are making dollar-based investments to support the growth of our customer base in the United States and global markets.

Research and development expense increased due to an increase of $4.7 million in personnel, and travel and entertainment costs, a net increase of $2.7 million in depreciation, outside services and other research and development costs, an increase of $2.1 million in costs of components for tools built for product development purposes, and partially offset by a $1.0 million decrease in stock-based compensation. We expect that, for the foreseeable future, research and development expense will increase in absolute dollars as we continue to invest in research and development to advance our technologies. We intend to continue to invest in research and development to support and enhance our cleaning, plating, advanced packaging, furnace, track, PECVD and future product offerings to build and maintain our technology leadership position.

General and administrative expense increased primarily reflecting a $3.3 million net increase in personnel costs, professional services costs, and other costs related to general and administrative expenses, partially offset by a $1.2 million decrease in stock-based compensation. We expect that, for the foreseeable future, general and administrative expense will
33

increase in absolute dollars, as we continue to invest in general and administrative by hiring additional employees and expanding in existing or new markets.

The increase in the unrealized gain from short term investments for the three months ended June 30, 2026 is mainly due to a significant increase during the period in the market price of certain of our holdings of publicly traded stocks which are listed on the Shanghai Stock Exchange. The increase in the income from equity investments for the three months ended June 30, 2026 is mainly derived from gain on disposal of available-for-sale securities held by our equity method investee.

Liquidity and Capital Resources

A detailed description of how cash is transferred through our organization is set forth under “note 2 – Summary of Significant Accounting Policies – Cash and Cash Equivalents” to the Consolidated Financial Statements of this report.

During the first six months of 2026, we funded our technology development and operations principally through our beginning global cash balances, including the cash balances at ACM Shanghai, borrowings by ACM Shanghai from local financial institutions, proceeds from issuance of ACMR shares, and proceeds from the sales of our shares and shares of our subsidiary. The $223.1 million increase in cash and time deposits was primarily driven by $332.6 million in net cash provided by financing activities, and a $18.9 million increase from the effect of exchange rate on cash, cash equivalents, restricted cash and non-cash items, offset by $35.9 million of cash used in operations, and $92.5 million of net cash used in investing activities, excluding the change in net cash related to time deposits.

Cash and cash equivalents, restricted cash, and time deposits:
     Cash and cash equivalents and restricted cash$990,587 $765,962 
      Short-term time deposits365,055 366,591 
Total$1,355,642 $1,132,553 

Our future working capital needs beyond the next twelve months will depend on many factors, including the rate of our business and revenue growth, the payment schedules of our customers, the timing and magnitude of our capital expenditures, and the timing of investment in our research and development as well as sales and marketing. We believe our existing cash and cash equivalents, and short-term time deposits, our cash flow from operating activities, and bank borrowings by us and ACM Shanghai will be sufficient to meet our anticipated cash needs within our longer term planning horizon.

ACM Shanghai has historically participated in certain mainland China government-sponsored grant and subsidy programs, as described under “—Mainland China Government Research and Development Funding” and “—Contractual Obligations” and we expect that ACM Shanghai will continue to take advantage of these programs when they are available and fit with our business strategy. ACM Shanghai generally applies for these grants and subsidies through the applicable mainland China government agency’s defined processes. Periodically, the public relations department researches the availability of these grants and subsidies through mainland China government agencies with whom ACM Shanghai files business surveys and taxes. Management of ACM Shanghai then assesses which grants and subsidies for which ACM Shanghai may be eligible and submits the relevant application. The decision to award the grant to ACM Shanghai is made by the relevant mainland China government agencies based on suitability and the merits of the application. Neither ACM Research, nor ACM Shanghai or any of our other subsidiaries, has any direct relationship with any mainland China government agency, and our anticipated cash needs for the next twelve months neither anticipate, nor require, receipt of any mainland China government grants or subsidies.

39

To the extent our cash and cash equivalents, cash flow from operating activities and short-term and long-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 obtain an equity or debt financing on terms acceptable to us or at all.

Restrictions under mainland China laws and regulations as well as restrictions under ACM Shanghai’s bank loan agreements, may significantly restrict ACM Shanghai’s ability to transfer a portion of ACM Shanghai’s net assets to ACM Research, other subsidiaries of ACM Research and to holders of ACM Research Class A common stock. See “Item 1A. Risk Factors – Regulatory Risks – Mainland China's currency exchange control and government restrictions on investment repatriation may impact our ability to transfer funds outside of mainland China, which could materially and adversely affect our ability to grow, make investments or acquisitions that could benefit our business, otherwise fund and conduct our business, or pay dividends on our common stock” in our 2025 Annual Report.

For the six months ended June 30, 2026 and 2025, with the exception of sales and services-related transfer-pricing payments in the ordinary course of business, no transfers or distributions have been made between ACM Research, and its subsidiaries, including ACM Shanghai, or to holders of ACM Research Class A common stock.

Our cash and cash equivalents at June 30, 2026 were held for working capital purposes and other potential investments. ACM Shanghai, our only direct mainland China subsidiary, is, however, subject to mainland China restrictions on distributions to equity holders.

The use of proceeds raised by the sales of shares by ACM Shanghai, and the STAR Market IPO, without further approvals, are limited to specific usage. We currently intend for ACM Shanghai, with the exception of dividends paid to shareholders of ACM Shanghai, to retain all available funds from any future earnings for use in the operation of its business. 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.

ACM Research has never declared or paid cash dividends on our capital stock. ACM Research intends 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 does not anticipate paying any cash dividends in the foreseeable future.
Cash Flow Used in Operating Activities. Net cash used in operating activities during the six months ended June 30, 2026 and 2025 consisted of:

The uses of cash were partially offset by a decrease in other payables and accrued expenses of $13.6 million.
Cash Flow Used in Investing Activities. Net cash used in investing activities, excluding the change in net cash related to time deposits, for the six months ended June 30, 2026 was $92.5 million, primarily consisting of purchases of property, plant and equipment of $87.3 million and purchase of long-term investments of $4.7 million with the remaining use attributable to intangible assets.

Cash Flow Provided by Financing Activities. Net cash provided by financing activities for the six months ended June 30, 2026 was $332.6 million, primarily consisting of $43.2 million in net proceeds and repayments of short-term and long-term borrowing (note 11), $148.4 million of proceeds from issuance of ACMR shares, $110.2 million of gross proceeds from sales of ACM Shanghai's shares, and $30.8 million of proceeds from the exercise of stock options.

(3)In May 2026, the Company entered into a loan agreement of RMB231,518 ($33,987) at a 2.65% interest rate, which was subsequently secured by a pledge of the property of ACM Shanghai (note 6) in July 2026.
Loan Covenants
In 2025, ACM Shanghai secured a long-term loan with the Bank of China (note 9) for ACM Shanghai’s project expenditures. The loan requires ACM Shanghai’s year-end outstanding interest-bearing debt not to exceed five times of its
42

annual EBITDA, and to comply with other non-financial covenants, or Bank of China has the right to suspend the loan, or request ACM Shanghai to accelerate repayment or provide credit enhancement.
Effect of exchange rate changes on cash, cash equivalents and restricted cash

The impact of fluctuations of the RMB to U.S. dollar currency exchange rate in RMB-denominated accounts (note 2) contributed to a $7.4 million increase in the value of these items during the six months ended June 30, 2026.
Contractual Obligations

Grant Contract for State-owned Construction Land Use Right in Shanghai City

In 2020, ACM Shanghai, through its wholly-owned subsidiary ACM Lingang, entered into a Grant Contract for State-owned Construction Land Use Right in Shanghai City (Category of R&D Headquarters and Industrial Projects), or the Grant Agreement, with the China (Shanghai) Pilot Free Trade Zone Lin-gang Special Area Administration, or the Grantor. ACM Lingang obtained rights to use approximately 43,000 square meters (10.6 acres) of land in the East China Silicon Hub of Lin-gang Special Area of China (Shanghai) Pilot Free Trade Zone for a period of fifty years, commencing on the date of delivery of the land in July 2020. For a description of the material terms of the Grant Agreement, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Contractual Obligations” in our 2025 Annual Report and see note 16 for additional detail.
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 shipment to a customer of a type of tool that the customer has previously accepted, for which we recognize revenue upon shipment or delivery, and (b) a first-time shipment of a first tool to a customer on an approval basis, for which we may recognize revenue in the future if contractual conditions are met, or if a purchase order is received.
We define “adjusted EBITDA” as net income excluding interest expense (net), income tax benefit (expense), depreciation and amortization, unrealized (gain) loss on short-term investments, 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 purchase of short-term and long-term investments.
We define “adjusted operating income (loss)” as our income (loss) 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 (loss) 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 (loss) 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 (loss) 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.
43

Shipments
We consider shipments a key operating metric as it reflects the total value of products delivered to customers and prospective customers by our productive assets.
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 or subject to the customer’s subsequent discretionary commitment to purchase the tool.
First tool shipments can be made to either an existing customer that has not previously accepted that specific type of tool in the past ─ for example, a delivery of a 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 six months ended June 30, 2026 totaled $522.2 million, as compared to $363.1 million for the same period in 2025. Repeat tool shipments in the six months ended June 30, 2026 totaled $266.2 million, as compared to $167.9 million for same period in 2025. First tool shipments in the six months ended June 30, 2026 totaled $256.0 million, as compared to $195.1 million for the same period in 2025.
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, or if the customer subsequently determines in its discretion to purchase the tool. There are a number of limitations related to the use of shipments in evaluating our business, including that customers have significant, or in some cases total, discretion in determining whether to accept or purchase our tools after evaluation and their decision not to accept or purchase delivered tools is likely to result in our inability to recognize revenue from the delivered tools. “First tool” shipments reflect the value of incremental new products under evaluation delivered to our customers or prospective customers for a given period and is used as an internal key metric to reflect future potential revenue opportunity. The cumulative cost of “first tool” shipments under evaluation at customers which have not been accepted by the customer is carried at cost and reflected in finished goods inventory (see Note 5 to the condensed consolidated financial statements included in this report). “First tool” shipments exclude deliveries to customers for which ACM Research does not have a basis to expect future revenue.
Adjusted EBITDA
There are a number of limitations related to the use of adjusted EBITDA rather than net income (loss), 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 (loss), 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; and
adjusted EBITDA includes expense reductions and non-operating other income attributable to mainland China governmental grants, which may mask the effect of underlying developments in net income, including trends in
44

current expenses and interest expense, and free cash flow includes mainland China 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$113,643 $85,585 32.8%$28,058 

We do not exclude from adjusted EBITDA expense reductions and non-operating other income attributable to mainland China 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 affected, to the extent we have accurately anticipated the amounts of the grants. For additional information regarding our mainland China grants, please see “—Mainland China Government Research and Development Funding.”
Free Cash Flow

The following table reconciles net cash (used in) provided by operating activities, the most directly comparable GAAP financial measure, to free cash flow:

Purchase of short-term and long-term investments(4,698)— NM(4,698)
Free cash flow$(127,905)$(71,077)80.0%$(56,828)

The reduction in free cash flow for the six months ended June 30, 2026 as compared to the same period in 2025 reflected the factors driving net cash used in operating activities, an increase of purchases of property and equipment, and long-term investments. Consistent with our methodology for calculating adjusted EBITDA, we do not adjust free cash flow for the effects of mainland China government subsidies, because we take those subsidies into account in incurring expenses and capital expenditures. We do not adjust free cash flow for the effects of time-deposits, which for our internal purposes are considered as largely similar to cash.

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. 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:

Item 3.    Quantitative and Qualitative Disclosures About Market Risks
Our market risks and the ways we manage them are summarized in the section captioned “Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in our 2025 Annual Report. There have been no material changes in the first six months of 2026 to our market risks or to our management of such risks.
Item 4.    Controls and Procedures

Evaluation of 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 pursuant to Rule 13a-15 under the Securities Exchange Act of 1934, or the Exchange Act, as of June 30, 2026. In designing and evaluating the disclosure controls and procedures, our management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that our management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs.

Based on such evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of June 30, 2026, our disclosure controls and procedures were effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended June 30, 2026, that have materially affected, or are 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 these proceedings 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.
Item 1A. Risk Factors

There were no material changes to the risk factors discussed in Item 1A. “Risk Factors” of Part I in our 2025 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.

Section 1 Loan Amount Currency of Loan: RMB Loan amount: (in words) Two hundred thirty one million five hundred eighteen thousand Yuan (in figures) ¥231,518,000.00 Section 2 Term of Loan Term of Loan: 120 months, commencing from the actual utilization date, or in case of utilization in installments, the first actual utilization date. The Borrower shall strictly utilize the Loan on the agreed utilization date(s). If any actual utilization date is later than the agreed utilization date, the Borrower shall still repay the Loan on such repayment date as specified herein. Section 3 Purpose of Loan Purpose of Loan: For purchasing the office building under the Building Property Title Certificate (Shanghai [2024] Pudong Real Estate No. 112919) (the “Property”). Without the written consent of the Lender, the Borrower shall not change the purpose of the Loan, including without limitation, using the Loan proceeds to purchase any property not specified herein, or repay any property mortgage loan, or distribute dividends to its shareholders, or invest in stock or other securities or financial assets, or any project that it is prohibited by the applicable laws, rules, regulatory provisions and national policies from accessing, or that has not been approved according to law, or relend to others, or purchase other financial products for purpose of arbitrage, or falsely increase fiscal revenues, or illegally incur new hidden local government debts, or in any other project or for any other purpose where the use of bank loans is prohibited. Section 4 Loan Rate, Calculation and Settlement of Interest 1. Loan rate


 
Page 2 of 19 Internal The loan rate (simple RMB loan rate per annum) set forth in Paragraph (1) shall apply: (1) Fixed rate: 2.65% per annum, which shall remain unchanged during the term of the Loan.  Source of interest rate for RMB loans: The □ 1-year / 5+-year loan prime rate (LPR) most recently published by the National Interbank Funding Center as of the business day preceding the effective date of this Contract, □ plus / minus 85 base points. (2) Floating rate: Starting from the actual utilization date, or in case of utilization in installments, the first actual utilization date, each □ day □ / months □ / years shall be a reset period, for re-pricing. The re-pricing date shall be the first date of the next reset period, which shall commence on the numerically corresponding day in the month in which the re-pricing occurs, or if there is no numerically corresponding day in that month, the last day of that month. If the reset period is one day, the re-pricing date shall be the day on which the next reset period commences. With respect to each utilization: □ Floating rate for RMB loans (A) The interest rate for the first period (i.e. from the actual utilization date till the expiry date of the current reset period) shall be the □ 1-year /□ 5+-year loan prime rate (LPR) most recently published by the National Interbank Funding Center as of the business day preceding the actual utilization date, □ plus /□ minus / base points. (B) At each re-pricing date, the interest rate shall be reset to the □ 1-year /□ 5+-year loan prime rate (LPR) most recently published by the National Interbank Funding Center as of the business day preceding the re-pricing date, □ plus /□ minus / base points, which shall be the interest rate applicable to all outstanding amounts during the current reset period. 2. Calculation of interest (1) With respect to the fixed rate set forth in Paragraph 1 Subparagraph (1) or the floating rate for RMB loans set forth in Paragraph 1 Subparagraph (2) above: Interest shall accrue from the actual utilization date, based on the actual amount utilized and number of days of utilization. Interest calculation formula: Interest = principal amount * number of days of utilization * daily interest rate. Daily interest rate shall be calculated on the basis of 360 days a year as follows: Daily interest rate = interest rate per annum/360. 3. Settlement of interest The Borrower shall settle interest in such manner as set forth in Subparagraph (1) below: (1) Settlement on a quarterly basis: The 20th day of the last month of each quarter shall be an interest settlement date, and the 21st day of that month shall be an interest payment date. (2) Settlement on a monthly basis: The 20th day of each month shall be an interest settlement date, and the 21st day of that month shall be an interest payment date. If the final repayment date for the principal of the Loan is not an interest payment date, then the final repayment date for the principal of the Loan is deemed an interest payment date, on which the Borrower shall pay all interest due. 4. Default interest


 
Page 3 of 19 Internal (1) If the Borrower fails to repay the Loan on time or use the Loan for the purpose set forth herein, default interest shall accrue on the overdue or misappropriated portion of the Loan, at the default rate set forth in this Paragraph 4, from the day immediately following the due date, or from the date of misappropriation (as the case may be), till the date on which all principal and interest have been paid in full. With respect to any portion of the Loan that is both overdue and misappropriated, the higher default rate shall apply. (2) If the Borrower fails to repay any interest or default interest on time, compound interest shall accrue at the default rate set forth in this Paragraph 4, and be settled pursuant to Paragraph 3 of this Section 4. (3) Default rate Default rate for RMB loans:  Default rate for fixed rate loans (A) Floating rate: □ / months □ one year shall be a reset period. The floating rate shall be reset for each reset period from the day immediately following the due date, or from the date of misappropriation (as the case may be). The re-pricing date shall be the numerically corresponding day of the day immediately following the due date, or the date of misappropriation (as the case may be) in the month in which the re-pricing occurs, or if there is no numerically corresponding day in that month, the last day of that month. (B) Default rate shall be the basic default rate set forth in Clause (C) below, plus 50% for any overdue portion of the Loan, or plus 100% for any misappropriated portion of the Loan. (C) In the first reset period, the basic default rate shall be the interest rate set forth in Paragraph 1 of this Section 4. In each subsequent reset period, the basic default rate shall be the □ 1-year / 5+-year loan prime rate (LPR) most recently published by the National Interbank Funding Center as of the business day preceding the re-pricing date, □ plus / minus 85 base points. □ Default rate for floating rate loans (A) The default rate shall be reset for each reset period set forth in Paragraph 1 of this Section 4, from the day immediately following the due date, or from the date of misappropriation (as the case may be). The re-pricing date for default interest shall be the numerically corresponding day of the day immediately following the due date, or the date of misappropriation (as the case may be) in the month in which the re-pricing occurs, or if there is no numerically corresponding day in that month, the last day of that month. (B) Default rate shall be the basic default rate set forth in Clause (C) below, plus /% for any overdue portion of the Loan, or plus /% for any misappropriated portion of the Loan. (C) In the first reset period, the basic default rate shall be the loan rate applicable in the month in which the default on payment or misappropriation occurs. In each subsequent reset period, the basic default rate shall be reset on the re-pricing date pursuant to Paragraph 1 of this Section 4. 5.
