ACM Research Shanghai backlog hits $2.5bn, up 88% year on year
ACM Research has disclosed that its Shanghai-listed subsidiary, ACM Research (Shanghai), held a total backlog of RMB 17.1 billion (approximately $2.5 billion) as of 29 September 2026, representing an 88.2% increase compared with the equivalent figure disclosed a year earlier. The data was posted to the Shanghai Stock Exchange website in accordance with Chinese listing requirements.
The backlog figure combines two categories: tools that have already shipped but whose revenue has not yet been recognised under Chinese GAAP, and orders for tools that are still pending shipment. ACM noted that backlog is not a standardised measure under either Chinese or US GAAP, and that its calculation methodology may differ from those used by peers. Orders in backlog do not carry a guarantee of revenue conversion.
Reporting timeline
ACM Shanghai is scheduled to publish nine-month financial results on 28 October 2026 after China market close. On the same day, the NASDAQ-listed parent will release preliminary nine-month figures before the US market opens. Full third-quarter results and an analyst conference call are expected in early November, with a specific date to be confirmed.
No executive commentary accompanied the backlog disclosure, and the release contained no detail on order composition by product line, customer geography, or shipment schedule.
Market context
The semiconductor equipment sector has experienced a sharp bifurcation in demand. Chinese domestic chipmakers, facing US export controls administered by the Commerce Department's Bureau of Industry and Security, have accelerated procurement from locally accessible suppliers. ACM Research occupies an unusual position in this landscape: it is a US-headquartered, NASDAQ-listed company whose manufacturing and primary customer base sit largely within China, giving it access to demand that is effectively closed to larger Western peers such as Applied Materials, Lam Research and Tokyo Electron.
That positioning carries its own risk. US export-control rules have tightened progressively since 2022, and ACM has previously disclosed that certain of its cleaning and plating tools fall into grey areas subject to regulatory review. A backlog figure of this size, growing at close to 90% annually, is likely to attract scrutiny from investors and policy analysts seeking to understand how much of the order book relates to tools that could become subject to new restrictions.
Investment read-across
For investors, a near-doubling backlog provides a positive leading indicator for revenue over the next four to eight quarters, contingent on conversion rates and any regulatory disruption. ACM's dual-listed structure, with shares trading in Shanghai under a separate entity and on NASDAQ as the parent, creates reporting complexity: the two sets of accounts are prepared under different accounting standards, and the October disclosures will offer the first detailed look at margin and cash-flow trends for the nine-month period.
The company operates across cleaning, electroplating, polishing, furnace processes, track, PECVD and advanced packaging tools. That breadth positions ACM across multiple nodes of the semiconductor manufacturing flow, though it also means that any category-specific demand shift or export restriction could affect a meaningful portion of the order book. Analysts will be watching the October results for detail on which product lines are driving the strongest backlog growth.
