ACM Research, Inc. is a Delaware-based supplier of advanced semiconductor manufacturing equipment that operates mainly through its 74.6%-owned subsidiary ACM Shanghai, which is listed on Shanghai’s STAR Market. The company focuses on wet cleaning, plating, furnace, PECVD, track and advanced packaging tools used in front-end and packaging processes.
In 2025, revenue was driven by single-wafer cleaning, Tahoe and semi‑critical cleaning equipment at $626.0 million, ECP, furnace and other technologies at $199.6 million, and advanced packaging, services and spares at $75.8 million. ACM estimates its current portfolio addresses about $21 billion of the 2025 global wafer fab equipment market, while Gartner pegs the overall market at $123.9 billion in 2025.
The business is heavily concentrated in Asia, particularly mainland China, and faces significant regulatory and geopolitical risk. ACM Shanghai and ACM Korea were added to the BIS Entity List in December 2024, restricting access to items subject to U.S. export controls. The company also highlights exposure to evolving mainland China regulations, potential HFCA Act-related trading prohibitions if PCAOB access changes, and broader U.S.–China trade, outbound investment and data-security regimes that could materially affect operations or even render Class A shares significantly less valuable or worthless.
ACM Research reported record 2025 revenue but weaker profitability. Full-year revenue reached $901.3 million, up 15.2% from 2024, with fourth-quarter revenue of $244.4 million, up 9.4%. Growth was driven by single-wafer cleaning, Tahoe and semi-critical tools, electrochemical plating, furnace technologies, and advanced packaging, services and spares.
Profitability softened as 2025 GAAP gross margin declined to 44.4% from 50.1%, and operating income fell to $109.4 million from $151.0 million. GAAP net income attributable to ACM Research, Inc. dipped to $94.1 million, with diluted EPS of $1.37 versus $1.53 a year earlier. The company ended 2025 with $1.13 billion in cash, restricted cash, and time deposits and net cash of $845.5 million, aided by a private offering at ACM Research (Shanghai), Inc. and a February 2026 sale of about 4.8 million ACM Shanghai shares for roughly $111 million.
Management is maintaining 2026 revenue guidance of $1.08 billion to $1.175 billion, implying 21–30% growth, and highlighted new tool shipments, expanding advanced packaging orders, and ongoing investment in an Oregon facility expected to begin operations in the second half of 2026.
ACM Research CEO David H. Wang reported the vesting of performance-based stock options tied to the company’s market value. On February 4, 2026, 545,400 stock options with a $7.36 exercise price became exercisable, bringing his total outstanding options to 1,636,197 shares of Class A common stock.
The options were originally granted on March 20, 2020 and vest in three tranches when ACM Research’s market capitalization increases by $1 billion, $2 billion, and $3 billion from $553,383,586 at grant. The latest vesting was triggered when market capitalization first reached or exceeded $3,553,383,586.
