--- title: "ACM Shanghai clears ¥6.8 billion as China's wafer cleaners take global share" date: 2026-11-11 category: Chips & Compute site: NeuroAI canonical: https://neuroai.site/a/na-chips-acm-shanghai-cleaning language: en --- # ACM Shanghai clears ¥6.8 billion as China's wafer cleaners take global share > The Shanghai-listed subsidiary of Nasdaq's ACM Research posted 2025 revenue and profit gains, underscoring how Chinese chip-equipment makers are moving from local substitute to global supplier. A wafer leaves a fab's cleaning bay spotless, but the machine that washed it was almost certainly not made in China a decade ago. Today that is changing, one tank of chemistry at a time. Shanghai-based ACM Research has become the rare Chinese equipment maker with a Nasdaq-listed parent and a customer list that spans both sides of the Pacific. ## Key takeaways - ACM Research (Shanghai) Inc. (盛美上海, 688082.SH) reported 2025 revenue of ¥6.79 billion (≈ US$940 million), up 20.80% year on year. - Net profit attributable to shareholders reached ¥1.40 billion (≈ US$194 million), up 21.05% — its third straight year of double-digit growth. - Its U.S. parent, ACM Research Inc. (Nasdaq: ACMR), booked consolidated 2025 revenue of US$901.3 million, up 15.2%, though group gross margin slipped to 44.4% from 50.1%. - The company cited Gartner's 2025 ranking placing its cleaning tools at an 8.0% global share (fourth) and electroplating at 8.2% (third). - Management guided 2026 revenue of ¥8.2–8.8 billion, a forward-looking target rather than a result. ## The cleaner that went global Wafer cleaning sounds unglamorous. Every chip passes through dozens of cleaning steps, and a single particle can ruin a device. For years the high-end cleaning and electroplating tools inside leading fabs came from Tokyo Electron, Screen, and Applied Materials. ACM Research built its name on a "space alternated isotropically" cleaning concept that attacked residue without damaging fragile structures — a differentiation strategy rather than a copy. That strategy now shows up in the books. According to the company's 2025 annual report, the Shanghai subsidiary's revenue rose to ¥6.79 billion (≈ US$940 million) from ¥5.62 billion in 2024, a 20.80% increase. Gross margin held at 48.32%, unusually high for capital equipment and a sign that customers pay for performance, not just price. ## What the numbers say Profit grew in lockstep with sales. Net profit attributable to shareholders was ¥1.40 billion (≈ US$194 million), up 21.05%, while operating cash flow turned positive at ¥239 million after a weaker 2024. Research spending jumped to ¥1.255 billion (≈ US$174 million), up 49.64% — a heavy bet that future growth depends on new platforms, not the current product line. The group view, filed by the Nasdaq parent, adds texture. ACM Research Inc. reported FY2025 revenue of US$901.3 million, up 15.2%, but gross margin fell to 44.4% from 50.1% a year earlier, and operating income dropped 27.5% to US$109.4 million. The parent attributed the margin pressure to product mix and currency effects. In February 2026 the parent also sold roughly 4.8 million shares of the Shanghai unit at RMB 160 each, trimming its stake from 74.8% to 73.7% and raising about US$111 million — a capital move, not a retreat. ## Why the ranking matters Market-share figures in chip equipment are usually quoted from Gartner or SEMI and treated as industry reference points. ACM cited Gartner's 2025 data showing its cleaning equipment at an 8.0% global share, ranking fourth worldwide, and its electroplating (ECP) tools at 8.2%, ranking third. If accurate, it means a Chinese supplier sits inside the global top tier of two foundational process steps — not yet a leader, but no longer a fringe player. Those numbers are company-cited rather than independently re-derived here, and fab-by-fab share shifts every quarter. They are best read as directional evidence that localization has crossed from "qualified alternative" to "default option" at some domestic fabs, where the company says certain key customers now source more than half their relevant tools from it. ## The advanced-packaging pivot ACM's revenue mix spans single-wafer cleaning, Tahoe and semi-critical cleaning, electroplating for both front-end and packaging, furnace technologies, and advanced packaging (先进封装). The last bucket matters most for the 2026 story. As leading-edge logic hits the limits of planar scaling, more value moves into advanced packaging — through-silicon vias, hybrid bonding, and chiplet integration — where cleaning and plating steps multiply. A maker strong in both front-end cleaning and packaging plating is positioned to ride that shift. The company's 2026 revenue guidance of ¥8.2–8.8 billion implies roughly 20–30% growth and reflects, in its words, current order trends and business development. Guidance is a forecast, not a result, and it carries the usual caveats around fab spending cycles and export controls. ## Honest limitations This article relies on the company's 2025 annual report, the Nasdaq parent's FY2025 results release, and financial-press summaries of those filings; it does not independently audit the figures. The Gartner market-share percentages are cited by the company and were not re-verified against Gartner's published tables. Forward-looking guidance for 2026 is management's projection and may miss. The piece focuses on financial and strategic signals and does not assess individual tool technical performance, customer concentration risk beyond what the filings disclose, or the effect of U.S. export controls on specific product lines. Localization share gains described here are directional, not measured at the fab level. ## What readers can do now - Track the quarterly cadence: ACM's results are a useful pulse check on Chinese domestic equipment demand because the Shanghai unit is a pure-play cleaning/plating supplier — watch revenue growth and gross margin each quarter. - Compare across peers: read Piotech (PECVD), Naura, and AMEC results alongside ACM to judge whether equipment strength is broad-based or company-specific. - Watch advanced packaging (先进封装) as the swing factor: if packaging-related tool revenue keeps climbing, it signals where the next wave of Chinese semiconductor investment is flowing. --- Published by NeuroAI (https://neuroai.site/) — https://neuroai.site/a/na-chips-acm-shanghai-cleaning Free to quote with attribution and a link to the original.
