    ACM Research (ACMR) Stock Could Be 42% Above Fair Value On Cash Flow

    Simply Wall St·09/23/2026 03:32:45
    Listen to the news

    ACM Research has seen a powerful share price run in recent years, which puts a spotlight on whether the cash the business can generate really backs up where the stock trades today. With that backdrop, the focus turns to what its cash flows suggest about the current valuation.

    • Over the past 3 years, ACM Research has delivered a return of about 3.5x, which raises the question of how much future cash generation is already reflected in the share price.
    • The company’s ability to convert revenue into steady cash inflows and reinvest in its semiconductor cleaning tools may support expectations for ongoing cash generation that matters directly for any intrinsic value estimate.
    • If you'd rather focus on earnings, this one's for you. See why ACM Research's 35.1x P/E tells a different valuation story.

    For investors, the debate is whether today’s US$75.8 price for ACM Research is adequately explained by the cash flows that the Discounted Cash Flow (DCF) estimate attributes to the business.

    If you are interested in other cash flow driven companies similar to ACM Research, it may be useful to compare this with a broader group using the 29 high quality undervalued stocks.

    Does ACM Research Look Pricey on Cash Flow?

    The Discounted Cash Flow, or DCF, model here is built on cash flow projections rather than earnings multiples. ACM Research is coming off a latest twelve month free cash flow loss of about $117.8 million, yet the model assumes that cash generation recovers and grows over time, reaching higher annual free cash flow by the early 2030s.

    Those projections support an intrinsic value estimate that sits substantially below the current US$75.80 share price. For you as an investor, the key question is whether the planned ramp in free cash flow that underpins the DCF feels realistic for ACM Research, or whether the market price is already baking in more optimistic outcomes than these projections imply.
