Additional research and development, service support and administrative activities are conducted at a multi-story leased facility also in Shanghai's ZhangJiang Science City.In addition, we perform sales support, customer service operations, R&D, and/ or production activities from leased facilities in Beijing, Chengdu, Jiangyin and Wuxi in mainland China and in Jinwi, Gwangju, Baekam, and Seongnam in Korea.

The rest of Item 2

ACM Shanghai, through ACM Lingang, conducts manufacturing, warehousing and R&D operations at its R&D and Production Center in the Lingang region of Shanghai. The five-building complex comprises more than 1,485,000 square foot of floor space in aggregate, and incorporates state-of-the-art manufacturing systems and automation technologies.

ACM Shanghai leases several facilities totaling more than 200,000 square feet, which are located in the Chuansha area of Shanghai and are used for R&D, production and warehousing.

In connection with the Lingang facility project, on October 28, 2020, a wholly owned subsidiary of ACM Lingang entered into Shanghai Public Rental Housing Overall Pre-Sale Contracts with Shanghai Lingang Industrial Zone Public Rental Housing Construction and Operation Management Co., Ltd. for an aggregate price to us of approximately $40 million. ACM Lingang’s subsidiary received ownership of the apartment units and corresponding land use rights in January 2022 as part of a pilot project of public rental housing in the “rent before sale” park in the Lingang Industrial Zone. The contracts stipulate that, for a ten-year term, ACM Lingang’s subsidiary is obligated to manage the apartment units for public rental use in accordance with public rental housing standards and must rent the apartment units to employees of ACM Shanghai and its subsidiaries who work in the Lingang Industrial Zone. After that ten-year period expires, ACM Lingang’s subsidiary may use the apartment units as stock of commercial housing and may sell them separately in sets.

We also lease a 10,683 square foot facility in Hillsborough, Oregon, which is used for our U.S.-based sales and services team to support customer activities in the region.

On October 1, 2024, we acquired a commercial facility, comprised of 39,500 square foot total floor space and which includes a 5,200 square foot functional clean room, for a price of $7.75 million. This facility is located in the City of Hillsboro in Oregon, and we have begun investments to expand our research and development, production, and demonstration capabilities in the United States market.

Risk factors and legal proceedings

The risks ACM Research, Inc. names in Item 1A of its 10-K filed Mar 2, 2026: 60 risks under these headings, as written.6

  • Risks Related to International Aspects of Our Business
  • Risks Related to Our Business and Our Industry
  • Regulatory Risks
  • Risks Related to the STAR Listing of ACM Shanghai
  • Risks Related to Our Intellectual Property and Data Security
  • Risks Related to Ownership of Class A Common Stock
  • 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.
  • 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.
  • It may be difficult for overseas regulators to conduct investigations or collect evidence within mainland China.
  • Because substantially all of our assets are located outside of the United States and certain of our officers reside outside of the United States, it may be difficult for you to enforce your rights based on the U.S. federal securities laws against such assets or officers or to enforce a judgment of a United States court against assets or officers in mainland China.
  • We conduct substantially all of our operations outside the United States and face risks associated with conducting business in foreign markets.
The other 54 risks
  • Fluctuation in foreign currency exchange rates may adversely affect our results of operations and financial position.
  • The exacerbation or further continuation of currently challenging global systemic economic and financial conditions could adversely affect our business, results of operations and financial condition.
  • We may require additional capital in the future and we cannot give any assurance that such capital will be available at all or available on terms acceptable to us and, if it is available, additional capital raised by us may dilute holders of Class A common stock.
  • Our quarterly operating results can be difficult to predict and can fluctuate substantially, which could result in volatility in the price of Class A common stock.
  • Cyclicality in the semiconductor industry is likely to lead to substantial variations in demand for our products, and as a result our operating results could be adversely affected.
  • We depend on a small number of customers for a substantial portion of our revenue, and the loss of, or a significant reduction in orders from, one or more of our major customers could have a material adverse effect on our revenue and operating results. There are also a limited number of potential customers for our products.
  • Our success will depend on industry chip manufacturers adopting our SAPS, TEBO, Tahoe, ECP, furnace and other technologies.
  • If our SAPS, TEBO, Tahoe, ECP, furnace and other technologies do not achieve widespread market acceptance, we will not be able to compete effectively.
  • If we do not continue to enhance our existing tools and achieve market acceptance, we will not be able to compete effectively.
  • Our success will depend on our ability to identify and enter new product markets.
  • If we fail to establish and maintain a reputation for credibility and product quality, our ability to expand our customer base will be impaired and our operating results may suffer.
  • We operate in a highly competitive industry and many of our competitors are larger, better-established, and have significantly greater operating and financial resources than we have.
  • Our customers do not generally enter into long-term purchase commitments, and they may decrease, cancel or delay their projected purchases at any time.
  • We may incur significant expenses long before we can recognize revenue from new products, if at all, due to the costs and length of research, development, manufacturing and customer evaluation process cycles.
  • Our sales cycle is long and unpredictable, which results in variability of our financial performance and may require us to incur high sales and marketing expenses with no assurance that a sale will result, all of which could adversely affect our profitability.
  • Difficulties in forecasting demand for our tools may lead to periodic inventory shortages or excess spending on inventory items that may not be used.
  • If our tools contain defects or do not meet customer specifications, we could lose customers and revenue.
  • Warranty claims in excess of our estimates could adversely affect our business.
  • We rely on third parties to manufacture significant portions of our tools and our failure to manage our relationships with these parties could harm our relationships with our customers, increase our costs, decrease our sales and limit our growth.
  • Our supply chain may be materially adversely impacted due to global events, including public health issues and the armed conflict in Ukraine.
  • Any shortage of components or subassemblies could result in delayed delivery of products to us or in increased costs to us, which could harm our business.
  • We depend on a limited number of suppliers, including single source suppliers, for critical components and subassemblies, and our business could be disrupted if they are unable to meet our needs.
  • The success of our business will depend on our ability to manage any future growth.
  • We are highly dependent on our Chief Executive Officer and President and other senior management and key employees.
  • Failure to attract and retain qualified personnel could put us at a competitive disadvantage and prevent us from effectively growing our business.
  • Acquisitions that we pursue in the future, whether or not consummated, could result in other operating and financial difficulties.
  • Declines in the semiconductor industry, or the overall world economic conditions on which the industry is significantly dependent, could have a material adverse impact on our results of operations and financial condition.
  • Our ability to sell our tools to customers in mainland China and certain other countries has been impacted, and will likely continue to be materially and adversely impacted, by export license requirements, other regulatory changes, or other actions taken by the U.S. or other governmental agencies.
  • Changes in government trade policies could limit the demand for our tools and increase the cost of our tools.
  • We may be subject to risks related to recent U.S. tariffs on the semiconductor industry
  • Changes in political and economic policies of the mainland China government may materially and adversely affect our business, financial condition and results of operations and may result in our inability to sustain our growth and expansion strategies.
  • 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.
  • Certain of our investments may be subject to review by and approval from CFIUS, which may prevent us from taking advantage of investment opportunities that would otherwise be advantageous to our stockholders.
  • The U.S. Government has implemented an outbound investment review mechanism, which may prevent us from taking advantage of investment opportunities that could otherwise be advantageous to our stockholders.
  • 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.
  • We are subject to government regulation, including import, export, economic sanctions, and anti-corruption laws and regulations, that may limit our sales opportunities, expose us to liability and increase our costs.
  • We may not achieve the results contemplated by our business strategy and our strategy for growth in mainland China may not result in increases in the price of Class A common stock.
  • ACM Shanghai’s status as a publicly traded company that is controlled, but less than wholly owned, by ACM Research could have an adverse effect on us.
  • ACM Research and ACM Shanghai both are public reporting companies but each is subject to separate, and potentially inconsistent, accounting and disclosure requirements, which may lead to investor confusion or uncertainty that could cause decreased demand for, or fluctuations in the price of, one or both of the companies’ publicly traded shares.
  • Our success depends on our ability to protect our intellectual property, including our SAPS, TEBO, Tahoe, ECP, furnace and other technologies.
  • We may be involved in lawsuits to protect or enforce our patents, which could be expensive, time consuming and unsuccessful.
  • We may not be able to protect our intellectual property rights throughout the world, including mainland China, which could materially, negatively affect our business.
  • If we are sued for infringing intellectual property rights of third parties, it will be costly and time consuming, and an unfavorable outcome in that litigation could have a material adverse effect on our business.
  • Breaches of our cybersecurity systems could degrade our ability to conduct our business operations and deliver products to our customers, result in data losses and the theft of our intellectual property, damage our reputation, and require us to incur significant additional costs to maintain the security of our networks and data.
  • The market price of Class A common stock has been and may continue to be volatile, which could result in substantial losses for investors purchasing our shares.
  • Few if any companies with stock publicly traded in the United States have effected a STAR Market listing of stock of a mainland China-based subsidiary, and it is therefore difficult to predict the effect of the STAR Listing and STAR IPO on the Class A common stock.
  • If securities or industry analysts do not publish research or reports about us, our business or our market, or if they publish negative evaluations of Class A common stock or the stock of other companies in our industry, the price of our stock and trading volume could decline.
  • We have never paid and do not intend to pay cash dividends and, consequently, your ability to achieve a return on your investment will depend on appreciation in the price of Class A common stock.
  • The dual class structure of common stock has the effect of concentrating voting control with our executive officers and directors, including our Chief Executive Officer and President, which will limit or preclude your ability to influence corporate matters.
  • Delaware law and provisions in our charter and bylaws could make a merger, tender offer or proxy contest difficult, thereby depressing the trading price of Class A common stock.
  • Our charter designates the Court of Chancery of the State of Delaware as the sole and exclusive forum for certain litigation that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers or stockholders.
  • We incur increased costs and demands upon management as a result of complying with the laws and regulations affecting public companies which could adversely affect our business, operating results and financial condition.
  • Short sellers of our stock may be manipulative and may drive down the market price of our Class A common stock.
  • Our production facilities could be damaged or disrupted by a natural disaster, war, terrorist attacks or other catastrophic events.

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. As of December 31, 2025, the Company had no outstanding material legal proceedings, other than ordinary routine litigation incidental to the business.
