    ACM Research (ACMR) Ships New System As Fresh Guidance Puts Fair Value Back In Focus

    Listen to the news

    ACM Research (ACMR) is back in focus after shipping its first 310 × 310 mm Ultra ECP ap-p panel-level electroplating system to an Asian customer and issuing fresh third quarter revenue guidance.

    Those product announcements and fresh guidance arrived in a choppy tape for ACM Research, with the share price at US$45.28 after a 1-month share price return that fell 45.69% and a 90-day share price return that declined 43.33%, even though the 1-year total shareholder return is 16.40% and the 3-year total shareholder return is about 19x. This suggests that the latest pullback may reflect shifting sentiment and perceived risk around execution rather than a break with the longer term story.

    After a 45% slide in a month, set against fresh product wins and new guidance, the question around ACM Research now turns practical: Does that reset justify stepping in today or waiting for a cleaner entry?

    Most Popular Narrative: 61% Undervalued

    ACM Research is trading at $45.28 against a widely followed fair value estimate of $115, which frames the recent slide as a valuation gap rather than a solved puzzle.

    Expansion from a focused cleaning vendor to a broader wafer fab equipment supplier, reflected in 168% year over year growth from ECP, furnace and other technologies to US$128.5 million in Q2 2026 and active evaluations for PECVD and panel level platforms, can widen ACM Research’s share of customer spend and support long term revenue scale.

    See why 90 investors see ACM Research as 61% undervalued.

    Result: Fair Value of $115 (UNDERVALUED)

    Still, ACM Research’s heavy exposure to Mainland China customers and ongoing U.S. China export control risk could quickly challenge the view that the stock is currently undervalued.
