What happened
ACM Research, Inc. (NASDAQ: ACMR) said its operating subsidiary, ACM Research (Shanghai), Inc., posted RMB 17.1 billion of backlog as of September 29, 2026. The company said that equals USD $2.5 billion and is an 88.2% year-over-year increase versus the prior year's disclosed backlog.
The release said the backlog includes tools already shipped but not yet recognized as revenue under Chinese GAAP and orders expected to ship later. All USD amounts are for reference only and translated using the September 29, 2026 Wall Street Journal closing exchange rate.
Key numbers
| Metric | Latest | Change | Source |
|---|---|---|---|
| ACM Shanghai total backlog | RMB 17.1 billion | ACM Shanghai backlog press release | |

| Year-over-year backlog increase | 88.2% | ACM Shanghai backlog press release |
Why it matters
OptimistFi's case is that ACM Research can create value if China-centered tool qualifications become durable share gains that recover margins and convert growth into cash. This filing is mixed for that thesis, because the backlog jump supports demand visibility, but it still does not show revenue, margins or cash flow.
The 88.2% increase is the main comparison in the release, yet backlog remains a snapshot that depends on future shipments and recognition. The filing also says backlog is not a financial measure and may not generate the estimated revenue, which limits how far investors can read into it. That is the strongest caveat the filing itself supports.

What's next
ACM Shanghai will report full results for the nine months ended September 30, 2026 on October 28, 2026 after the market close in China. On the same day, ACM will report preliminary nine-month results before the market open in the U.S. ACM also said full third-quarter 2026 results and a conference call are due in early November 2026.
The filing said the specific reporting date and conference-call details will be released later. Investors will care most if that report shows backlog moving into revenue and cash, or if it remains only a backlog snapshot. A weaker report would keep the filing's backlog figure from turning into proof of durable operating improvement.
