ACM Research (ACMR) is back in focus after raising its full year 2026 revenue guidance to a range of US$1.125b to US$1.175b, following a strong second quarter earnings report.

Despite the raised guidance and strong recent earnings, ACM Research’s share price has eased in the short term, with a 1-month share price return down 12.55% and a 7-day share price return down 4.03%. This pullback sits against a much stronger backdrop, including a 90-day share price return of 26.31%, a year to date share price return of 79.19% and a 1-year total shareholder return of 221.42%. Together, these figures point to momentum that has been building over a longer horizon.

After the sharp run over the past year and the recent pullback, ACM Research now trades well below the average analyst price target and above some intrinsic value estimates. Where does a reasonable fair value range actually sit within that spread?

Most Popular Narrative: 21.3% Undervalued

Against ACM Research’s last close of $80.42, the most followed narrative points to a fair value of $102.14, which implies a meaningful gap that rests on specific growth and margin expectations rather than short term trading swings.

Recent major investments in new manufacturing and R&D capacity (Lingang in China and Oregon in the US), plus strategic inventory buildup to manage supply chain/geopolitical risks, position ACM to support expanding global sales, mitigate supply disruptions, and scale operations efficiently, which will eventually benefit gross margin and earnings stability.

However, ACM Research’s heavy reliance on mainland China and ongoing export control risk, combined with elevated R&D and inventory levels, could challenge the bullish fair value story.

Another View: ACM Research Through a Cash Flow Lens

While the most followed narrative sees ACM Research as undervalued relative to a $102.14 fair value, the SWS DCF model paints a stricter picture. On that basis, the current $80.42 share price sits above an estimated future cash flow value of $48.40. This suggests ACM Research may be trading at a premium rather than a discount.
