ACM Research, Inc. (ACMR): fair value, margin of safety and Wheel Score

Is ACMR undervalued?
ACM Research, Inc. (ACMR) closed at 58.09 on 16 Oct 2026, close to the GLS average fair value of 63.18 (8.1% below fair value). 2 of the 6 models that produced a number sit above the price, 4 below - the market and our models roughly agree. With little margin of safety either way, the case for or against the stock rests on the quality numbers and the option premium rather than on price.
There is a wide gap between DCF (0.2214) and GLS Growth (135.47). When the models are this far apart the "fair value" is really a range, and the margin of safety above should be read with that range in mind.
The nightly engine files ACMR under Speculative / Distressed - negative earnings or a Piotroski score of 3 or less - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.

| Lynch | 55.32 | -5% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 135.47 | +133% | EPS compounded ten years at the blended growth rate, discounted back at 15% a year |

Quality and financial health
ACM Research, Inc. scores only 3 of 9 on the Piotroski F-score, which fails the Sunday Scan's "6 or more" rule. A reading this low means several of the basic tests - positive earnings, positive operating cash flow, falling debt, no new share issuance - are not met. A GLS Moat score of 3.5/10 is a weak reading: the ten-year history the score grades (revenue, EPS, book value, margins, cash flow, share count, ROIC) has not been steady, so the Moat part of the Wheel Score contributes little.
Returns on capital are moderate - ROIC 5.3%, ROE 6.4%, ROA 3.3% - with debt at 0.21 times equity and negative free cash flow.
ACM Research, Inc. pays no dividend, so the DDM model does not apply and a covered-call holder earns only the premium and any price gain. Revenue comes mainly from ECP Front End And Packaging Furnace And… 80%, Advanced Packaging (exclude ECP), Servi… 20% (quarter Q2 FY2026).
Institutional ownership scores 9/10, insider activity 1/10 and Congressional trading 5/10 on the GLS smart-money scales.
| Piotroski F-score | 3 / 9 | ROIC | 5.3% |
|---|---|---|---|
| GLS Moat | 3.5 / 10 | ROE | 6.4% |
| Debt / equity | 0.21 | ROA | 3.3% |
| Free-cash-flow yield | -3.2% | Payout ratio | 5% |
| Institutions | 9 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 45: Weak
With a Wheel Score of 45 ACM Research, Inc. sits in the Weak band, capped at 45 because the engine files it as Speculative / Distressed. The parts - Value 16/25, Health 7/20, Moat 5/15, Premium 13/20, Stability 15/20 - show where: Moat (5/15) scores lowest.
Implied volatility is 88% on the near-the-money contracts 20-60 days out - above the 60% ceiling of the sweet spot. Premiums are large, but the Wheel Score tapers the Premium points (13 of 20) because volatility this high usually comes with a reason. Chain open interest is 40,424 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 2.0M shares a day on a market cap of $3.8B, with a beta of 2.09 - a high beta, so the stock tends to move more than the market and a strike can be gapped through; the Stability part of the Wheel Score gives that 15 of 20.
| Part | Points | From | |
|---|---|---|---|
| Value | 16 / 25 | 8% margin of safety | |
| Health | 7 / 20 | Piotroski 3/9 | |
| Moat | 5 / 15 | moat 3.5/10 | |
| Premium | 13 / 20 | implied volatility 88% | |
| Stability | 15 / 20 | 2.0M shares/day, $3.8B cap, beta 2.09 |
