ACM Research, Inc. (ACMR): fair value, margin of safety and Wheel Score
Ticker symbol ACMR · Technology · Semiconductors · United States · Class A common stock · Speculative
ACMR is ACM Research, Inc.'s Class A common stock. The classes own the same business, share the same earnings report and trade within a few cents of each other; what differs is mainly the vote each share carries - the company's annual report sets out the voting rights.
Is ACMR undervalued?
ACM Research, Inc. (ACMR) closed at 44.43 on 5 Nov 2026. The GLS average fair value - the simple average of the 7 valuation models that produced a positive number - is 54.41, so the price sits 18% below it. 3 of the 7 models value the shares above the current price. A margin of safety between 10% and 30% is where most of the Sunday Scan candidates come from.
There is a wide gap between DCF (0.2527) 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 - it is losing money or its Piotroski health score is 3 or lower - which caps its Wheel Score at 45 and keeps it out of the Sunday Scan.

| Model | Value | vs price | What it measures |
|---|---|---|---|
| DCF | 0.2527 | -99% | Present value of the projected free cash flows, discounted at the cost of capital |
| Graham Number | 36.93 | -17% | The most a defensive investor pays for the earnings and book value per share |
| Graham Growth | 126.57 | +185% | Graham's growth formula: EPS × (8.5 + 2 × growth), adjusted for bond yields |
| Lynch | 55.32 | +25% | EPS × the earnings growth rate (PEG of 1), growth capped at 25% |
| GLS Growth | 135.47 | +205% | 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 "Piotroski 6 or more" Wheel Trade Filter. 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 4.7/10 is a weak reading: the accounts do not show returns and margins that competitors have been unable to wear down, 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.
The dividend yield is 0.26% with a payout ratio of 5% - a small yield that leaves most of the earnings in the business. 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 | 4.7 / 10 | ROE | 6.4% |
| Debt / equity | 0.21 | ROA | 3.3% |
| Free-cash-flow yield | -4.2% | Payout ratio | 5% |
| Institutions | 9 / 10 | Insiders · Congress | 1 · 5 / 10 |
Wheel Score 31: Weak
With a Wheel Score of 31 ACM Research, Inc. sits in the Weak band. It fails filter 2, a real business, not a gamble - speculative (a loss, or a weak Piotroski score); and filter 4, financially healthy - Piotroski 3/9 (under 6); and filter 5, can repay its debt - debt with no positive cash flow to repay it; and filter 7, a premium worth selling - implied volatility 91% (over 80%); Stability (weak) is its weakest part.
Implied volatility is 91%, above the 80% ceiling of the Wheel Trade Filter on premium. The premium looks generous, but moves of that size can blow through any strike. Chain open interest is 15,091 contracts across all expiries - enough for the wheel at normal size.
Volume runs at 1.7M shares a day on a market cap of $2.9B, with a beta of 2.23 - 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 rates that weak.

|---|---|---|---|
| 1 | Options that actually trade | Passes | Listed options with 1,000+ contracts of open interest and 100+ traded a day |
| 2 | A real business, not a gamble | Fails | speculative (a loss, or a weak Piotroski score) |
| 3 | Below fair value | Passes | Trading below the nine-model average fair value (margin of safety above 0) |
| 4 | Financially healthy | Fails | Piotroski 3/9 (under 6) |
| 5 | Can repay its debt | Fails | debt with no positive cash flow to repay it |
| 6 | No serious red flags | Passes | Red Flags score 60 or more out of 100 (earnings, margins, debt, analysts, filings and price checked the same way for every stock) |
| 7 | A premium worth selling | Fails | implied volatility 91% (over 80%) |
| 8 | Big enough | Passes | Market cap $1 billion or more |
