ACM Research, Inc. (ACMR) Stock Analysis
ACM Research, Inc.
▾ What's in the 42/100 risk score? (higher = riskier)
Contributions (weight × component score) sum to the total. This near-term score now includes fundamental health (leverage, FCF trend). It excludes the Altman Z score, whose retained-earnings input this filer does not report separately. See the Financial Health section for the full balance-sheet read.
How to read ACMR
We are not publishing an intrinsic value for this one — the section below says exactly why. Everything on this page that comes straight from the filings and the tape is still here; treat the missing valuation as a known gap, not as a verdict on the business.

1
Reported earnings & margins ↓
What the company actually reported — unaffected by the valuation being held.

2
Balance sheet & book value ↓
Assets, liabilities and equity as filed.

Insider and short-interest behaviour needs no valuation model.
The share count we read for ACMR looks wrong — common for multi-class / founder-controlled filers that report shares per share-class. That makes per-share figures (including intrinsic value) misleading, so we suppressed them. The company's total financials below are sound.
What to use instead: Lean on the totals — revenue, net income, cash flow — and the balance sheet. Multi-class share counts are being corrected; once fixed, the per-share valuation returns automatically.
This note is only about the single DCF fair-value number — ACMR's full financial statements, health scores, and written analysis are all below.
⚠ We found only 3 genuine same-industry (Special Industry Machinery) comparables — fewer than the 4 we require for a reliable median. The 8 names in the table below therefore include 5 broader Industrials names marked fallback, whose business models and margins differ — which is why any median below is computed over that wider set, not over true comparables. So we do not derive a peer-implied share value here. Read the multiples as rough context only.
How does ACMR stack up against its closest peers?
Ideally we compare ACMR only to same-industry peers, but too few exist in our universe right now, so the basket below mixes in broader-sector names. Treat the multiples as rough context, not a valuation. For a leveraged business, EV/EBIT and FCF yield (both in the table) are usually more reliable than EV/Sales, because revenue multiples ignore differences in margins and debt.
▾ What's "EV / Sales" in plain English?
EV (Enterprise Value) = market cap + total debt − cash. It's "what you'd pay to buy the entire company outright" — you pay the market cap to shareholders and take over their debt, but you keep their cash. EV is fairer than market cap alone because it includes the debt the new owner inherits.
EV / Sales = EV ÷ annual revenue. So "2.5×" means investors pay $2.50 of enterprise value per $1 of yearly sales. Higher = market is paying more per dollar of sales (usually because they expect future growth or fat margins).
p25 / median / p75 are the 25th, 50th (middle), and 75th percentile of the peers' multiples. Half the peers fall between p25 and p75. The median (p50) is the typical peer — that's the benchmark we compare to.
| EV / SalesEV / Sales — For every $1 of yearly revenue, this is how many dollars investors pay to own the whole business (including debt). Why it matters: Works for pre-profit growth companies where P/E and FCF don't apply. The most apples-to-apples cross-company multiple because it ignores accounting choices. Reference: 1–3x for mature companies · 4–10x for software/SaaS · 10–20x for hypergrowth · >20x is rare and demanding Full explanation → |
0.8x / 3.6x / 5.5x |
| EV / Gross ProfitEV / Gross Profit — Enterprise value divided by gross profit — the multiple paid for what each dollar of sales contributes after direct costs. Why it matters: More refined than EV/Sales for high-margin businesses (software, marketplaces) where gross margin is the real economic engine. Reference: 8–15x for SaaS · 15–25x for hypergrowth software · >30x demanding Full explanation → |
5.8x / 9.4x / 12.3x |
| EV / EBITEV / EBITDA — Enterprise value divided by earnings before interest, tax, depreciation, and amortization. Why it matters: A classic "what would a private buyer pay" multiple — used in M&A. Strips out tax and capital-structure noise. Reference: 8–12x for mature businesses · 15–25x for growth · Below 5x often signals distress Full explanation → |
16.3x / 20.3x / 38.7x |
Bold middle number = median peer. Half the peers trade above it, half below. Computed over 8 peers (broad — see caveat); implausible multiples excluded.
⚠️ Important caveat: peer multiples only work if the peers are genuinely comparable. Always check the peer list below — if the auto-picker grabbed micro-caps or unrelated businesses, the comparison is noise. A medical-device giant priced against tiny biotech startups won't produce a useful signal.

Quality & solvency checks
Cheap stocks can be cheap for a reason. These screens warn when a low valuation comes paired with structural fragility.
Why it matters: Cheap-looking stocks (low P/E or P/B) often have low Z-scores because the market knows the company is dying. Z-score warns you before you fall into a value trap.
Reference: > 3.0 = safe zone · 1.81–3.0 = grey zone · < 1.81 = distress zone
Full explanation →
We can't produce a trustworthy Altman Z here: retained earnings weren't separately reported in our data, so a core input would have to be fabricated. Rather than show a categorical "distress" verdict from an invented number, we mark it unavailable. Judge financial health from the leverage, cash position, and the measurable Piotroski checks instead.
Why it matters: High score = fundamentals improving. Low score = deteriorating. Especially powerful for filtering cheap stocks: cheap + high F-score historically outperforms; cheap + low F-score is often a value trap.
Reference: 7–9 = strong · 4–6 = mediocre · 0–3 = weak

▾ The checks — what passed, what didn't (and what we couldn't measure)
-
✓ Positive net incomeNet income $94.1M in FY2025.
-
✗ Positive operating cash flowOperating cash flow -$10.3M (was $152.5M the prior year).Why this matters: Profit can be an accounting figure; cash from running the business is harder to fake. Negative operating cash flow means the core business consumes cash and must be funded externally.
-
✗ Cash flow backs up reported profitOperating cash flow -$10.3M vs net income $94.1M.Why this matters: When cash generated exceeds reported earnings, profits are high-quality (not propped up by accruals or one-time items).
-
✗ Return on assets improvingReturn on assets 3.3% vs 5.6% a year ago.Why this matters: Is the company squeezing more profit out of each dollar of assets than last year? Rising = getting more efficient; falling = the opposite.
-
✓ Debt load (vs assets)Long-term debt is 7.5% of assets vs 8.1% a year ago ($214.0M of $2,872.2M assets).
-
✓ Short-term liquidity (current ratio)Current ratio 3.27x vs 2.31x a year ago.
-
✗ Share count (dilution)Share count rose 1.6% (66.2M → 67.3M year-over-year).Why this matters: Issuing lots of new shares splits the pie into more pieces, shrinking your slice. Stable or falling share count protects existing owners.
-
✗ Pricing power (gross margin)Gross margin 44.4% vs 50.1% a year ago.Why this matters: Rising gross margin means stronger pricing power or lower input costs — a sign of competitive strength. Falling margin signals pressure.
-
✗ Sales per asset (asset turnover)Asset turnover 0.31x vs 0.42x a year ago.Why this matters: Asset turnover measures how much revenue each dollar of assets generates. Rising = more productive use of the asset base.
Missing data is never counted as a pass or a fail — it's shown as n/a and excluded from the denominator. Each check compares the company against its own prior year.
What if you assume different inputs?
Here's where we land — and what happens if you change the assumptions. Drag the sliders to set your own Discount RateDiscount Rate — The annual return you demand for taking single-stock risk instead of buying a safe Treasury or index fund.
Why it matters: Higher discount rate = stricter valuation (a stock has to produce more cash to be worth holding). Lower = more generous.

Note: no headline intrinsic value is published for this stock (the valuation is held for a data-quality reason — see the notes above). The calculator below is a what-if tool: the values it produces are your assumptions played out, not our estimate.
A full intrinsic value isn't shown for ACMR because the valuation is currently held for a data-quality reason (see the guardrail notes above). The reverse-DCF reading still works — it needs only the price and cash flow — but we won't publish a forward value until the underlying data passes our checks.

⚙ Advanced — tinker with every input (beta, growth, rate path, margin → full intrinsic value)
A standard discounted cash flowDCF — Discounted Cash Flow — sums up all future cash a business will produce, adjusted for the fact that future dollars are worth less than dollars today.
Why it matters: It is the most fundamentally honest valuation method when applicable — but only works for companies with predictable, positive cash flow.
Reference: Best for: mature, profitable businesses. Fails for: pre-profit growth, banks, REITs.
Full explanation → (DCF) valuation is not meaningful for ACM Research due to its negative operating cash flow, which makes traditional cash flow projections unreliable. The market appears to be pricing in significant future growth and optionality, as evidenced by the price being 5.9 times the model's intrinsic valueIntrinsic Value — Our DCF model's estimate of what each share is mathematically worth based on projected cash flows.
Why it matters: Compare to current price. Below IV = potentially undervalued. Above IV = priced for growth that must actually happen.
Reference: Model-derived; quality depends on data and assumptions.
Full explanation →. Investors are likely betting on the company's ability to convert its revenue growth into sustained positive operating cash flow and profitability. The primary quantifiable risk is the rising long-term debt, which has increased from $23M to $214M.

Anatomy of a share
What you're buying per share. Bars are at the same scale so you can see the relative size of revenue, costs, cash flow, and debt — not just read them in a table.
What's free cash flow / what do these mean?
Revenue per share — how much the business earns from customers, divided by the number of shares outstanding. Top of the income statement.
Earnings per share — profit left after operating costs, interest, and taxes, per share. Two versions appear on this page and are not interchangeable: GAAP diluted EPS uses the company's weighted-average diluted share count during the reporting period (this is the "earnings" in "price-to-earnings"); net income per current share divides annual net income by today's share count. They differ whenever the share count has changed.
Owner-earnings free cash flow per share — the cash the business produces for shareholders. Savng's owner-earnings FCF subtracts capital expenditures and stock-based compensation from operating cash flow (SBC is a real dilution cost even though it's non-cash). This is deliberately more conservative than "standard" FCF, which subtracts only capital expenditures — so our figure is lower than the headline FCF you'll see elsewhere. FCF funds dividends, buybacks, debt repayment, and acquisitions; a company can report positive earnings yet negative FCF.
Debt per share — total interest-bearing borrowings divided by shares. High debt-per-share next to thin FCF-per-share is a fragility signal.
What you actually need to decide
Every stock price is a disagreement. Here's the single thing that must go right for the bulls, the single thing that breaks the thesis, and the concrete signposts to watch so you can update your view as real results arrive.
- Next quarter's operating cash flow trend
- Announcements of new product wins or market share gains
- Updates on long-term debt levels and financing activities
The trend, in plain numbers (FY2024 → FY2025, latest reported)
Straight from the financial statements — no model, no opinion. For a small or unprofitable company, the direction of these numbers usually tells you more than any single valuation.
- Revenue grew +15% to $901.3M.
- Free cash flow is negative at -$100.2M — the cash burn widened vs last year.
- Gross margin shrank to 44% (-6 pts).
- Net income fell -9% to $94.1M.

End Markets
Revenue Drivers
Why Is It Priced Like This?
Why Customers Pay
What we use instead: earnings (P/E, EV/EBIT), book value (P/B) — computed from the figures this company does report, shown in the sections below. Those numbers are unaffected by the missing cash-flow data.
The market is likely pricing ACM Research based on its robust revenue growth of 36.5% per year over four years and its consistent net income profitability over the last five years, despite negative operating cash flow. The market may be assigning value to the company's potential to capture a larger share of the growing semiconductor equipment market, which is not in the model, or to future technological advancements in its product pipeline that could significantly expand its addressable market.
Business Model & Valuation
How They Make Money
The company funds itself primarily through equity raises and debt, as evidenced by rising long-term debt from $23M to $214M, given its negative operating cash flow.
Growth / Revenue DCF
Negative free cash flow: revenue/margin growth model used - standard FCF DCF is unreliable for companies still scaling.
Show advanced inputs
| Revenue Growth | 36.5% |
What this model does NOT do: this is a consolidated owner-earnings FCF model. Standalone segment assumptions: none. It does not project its revenue segments independently; their combined effect is embedded in the historical revenue and cash-flow trend the model extrapolates. The calculator above can only approximate a segment's impact through the single consolidated growth rate — it cannot model any one line separately. For a true segment-level view, build a separate model from the company's segment disclosures.
Maturity & Competitive Position
Moat Signals
Revenue has grown significantly at 36.5% per year over four years, from $260M to $901M, and net income has been positive for five out of five years.
Geography & Markets
ACM Research is headquartered in the US but has significant operations and customer bases in Asia, particularly in China, which is a major market for semiconductor manufacturing equipment. Exact geographic revenue mix percentages are not available from current data sources.

Market Signals
These are timing signals, not value signals — they describe the stock's recent price behavior, not what the business is worth. Use them for the "the thesis looks good, but is now the moment?" question. Each tile below explains what it's saying.
Why it matters: Short-term contrarian indicator. Extreme readings often precede mean reversion, though not always.

Why it matters: When the fast line crosses above the slow line, short-term momentum is turning up; below, turning down. A timing cue, not a value signal.
Reference: Line above signal = bullish momentum · below = bearish
Full explanation →BullishLine above signalThe fast trend is above the slow trend — short-term momentum is currently upward.
Technicals describe price, not the business. A great company can have a "bearish" tape (a buying chance) and a weak one a "bullish" tape (a trap). Pair these with the valuation and health sections above.
QUALITY
Data Quality & Risk Flags (4 notes — click to expand/collapse)
Guardrail Notes (4)
- FCF negative: revenue/margin growth model projects future cash flows from revenue trajectory.
- Price is far above the model output - market may be pricing optionality, narrative catalysts, or margin expansion beyond what trailing cash flows support.
- Extreme valuation (P/IV withheld — see the note above); output dominated by data/units issue (often a multi-class share-count mismatch). Suppressed.
- DATA UNAVAILABLE: per-share values suppressed due to missing/unreliable shares data.

How we define FCF: operating cash flow − capital expenditure − stock-based compensation (owner-earnings basis — SBC is a real cost to shareholders even though it's non-cash). Latest year: -10.3M − 56.3M − 33.6M (SBC & adj.) = -100.2M. This is the same owner-earnings FCF definition the valuation model uses, though the DCF's starting value is a projected from revenue × terminal margin, not this single year.
