ACM Research Shanghai's Order Backlog Hits RMB 17.1 Billion, Up 88% From A Year Ago
The Chinese subsidiary's disclosed backlog now stands at roughly $2.5 billion, setting expectations ahead of October 28 results.
ACM Research's Shanghai subsidiary disclosed an order backlog of RMB 17.1 billion — equivalent to about $2.5 billion — as of September 29, 2026, an 88.2% jump from the prior year's disclosed figure. The company brought the data into the U.S. regulatory record through an 8-K filed Wednesday with the SEC.
What The Filing Says
ACM Research (Shanghai) routinely posts backlog figures on the Shanghai Stock Exchange website; Wednesday's 8-K filing attached the same data as Exhibit 99.1, making it part of the U.S. regulatory record.
The 88.2% year-over-year increase covers the total backlog as of September 29, 2026, translated to dollars at the Wall Street Journal's closing exchange rate for that date. The press release is explicit that all U.S. dollar figures are for reference only.
The backlog figure bundles two distinct categories: tools that have already shipped but whose revenue has not yet been recognized under Chinese accounting standards, and tools that are expected to ship at a future date. The company cautioned that backlog is not a defined measure under either Chinese or U.S. accounting standards, and that ACM Shanghai's methodology and underlying assumptions may not be comparable to those used by other companies. The press release also noted that orders included in the backlog may not actually generate the revenue amounts estimated.
What It Changes For Holders
The near-doubling of the backlog figure is the most concrete forward-looking data point ACM Research has put into the U.S. regulatory record ahead of its next scheduled reporting cycle. It will set the baseline against which investors measure the nine-month results due October 28.
ACM Research develops, manufactures, and sells semiconductor process equipment — tools used in cleaning, electroplating, stress-free polishing, vertical furnace processes, track, PECVD, and wafer- and panel-level packaging steps of chip manufacturing — through its Shanghai-listed subsidiary. The parent company is headquartered in Fremont, California, and its Class A common stock trades on Nasdaq under the ticker ACMR.
ACMR shares edged up about 0.5% to $83.98 in Friday trading, according to market data, as the backlog disclosure circulated ahead of the upcoming results dates.
What To Watch
ACM Shanghai will release its full nine-month financial results on October 28 after the China market closes. On the same day, ACM Research will report preliminary nine-month results before the U.S. market opens.
Full third-quarter results and a conference call are expected in early November 2026. The company said the specific reporting date and conference call details will be announced at a later date.
The 8-K was signed by Mark McKechnie, ACM Research's chief financial officer and treasurer, dated September 30, 2026.
The next hard date on the calendar is October 28, when both the Shanghai subsidiary's full nine-month results and ACM Research's preliminary nine-month figures are scheduled to land on the same day.
