ACM Research Shanghai: A Genuine Platform Story, Priced for Zero Margin of Safety
ACM Research Shanghai is the Shanghai-listed operating core of a dual-listed Chinese semiconductor wet-process equipment group, whose U.S. parent ACM Research (ACMR.US) holds a 73.6% stake but trades at a steep discount to the A-share line's implied look-through value. 2025 revenue rose 20.8% to CNY 6.79 billion and net profit rose 21.1% to CNY 1.40 billion, but operating cash flow collapsed to just CNY 239 million from CNY 1.22 billion and turned negative in the first quarter of 2026, even as the stock trades near 130 times trailing earnings and about 180% above the parent-implied look-through value. Rating Watch: the platform story is real, but the price already assumes near-flawless execution while cash conversion has weakened, with the ideal buy zone at CNY 140 to 150.
