The five investor questions

95

2021–2025 (latest 5 aligned FYs; v3 window cap 5): revenue $260M to $901M, increasing; diluted EPS 0.58 to 1.37, increasing. Latest-filed diluted EPS remains usable for Business Trend, but an integer share-count change lacks enough evidence to confirm a comparable EPS basis; valuation growth therefore stays at 0%.

78

Median gross margin 47.1% over 10y, very stable.

70

Median ROIC 16.6%, above the 12% hurdle in 56% of years.

89

Net cash position — no leverage risk.

62

Owner earnings changed +65.1%/yr over up to the ten most recent annual observations.

Price vs. value if growth stopped today

A cautious baseline, not a price target: what the shares may support if normalized owner earnings simply hold steady.

This zero-growth estimate assumes trailing owner earnings persist — unreliable for declining businesses. The recent FY revenue series does not trigger the three-consecutive-declines flag.

Among the current top-score group, the median current price is 239% above the zero-growth estimate across 48 of the current top 50 companies by Moat Score with both values.

11 years of fundamentals

The business, in plain English

ACM Research, Inc. booked $901M of revenue in FY2025 in the Industrials sector and kept 44.4% of it as gross profit — a solid-margin business by that measure. After every other cost, 10.4% of each revenue dollar reached the bottom line.

Across the filed record, revenue grew from $27.4M (FY2016) to $901M (FY2025) — about 47.4% a year compounded over 9 years.

It earned 9.9% on invested capital in the latest filed year, FY2025. Across the full 9-year measurable filed record, median ROIC was 16.6%. Over the v3 recent window (9 measurable filed years), median ROIC was 16.6%. The Returns on Capital filter above scores it 70/100.

The balance sheet carried $288M of total debt in FY2025 against $94.1M of owner earnings — roughly 3.1 years of owner earnings to retire it all. Balance-Sheet Safety scores it 89/100.

Put together: Business Trend is the strongest of the five filters (95/100) and Capital Allocation the weakest (62/100), which is how ACMR lands at 79/100 — a Narrow moat.

This breakdown is generated from the filed numbers and sub-scores above — no outside narrative, no estimates. Where a filing doesn’t disclose an input, the sentence that would need it is omitted instead of guessed.

Insider activity

Form 4 reports mix P/S market or private transactions with compensation-plan mechanics. Activity casually described as “insider selling” can include compensation mechanics; awards, tax withholding, and option exercises are shown by their exact filed class here, never collapsed into “Bought” or “Sold.”

These are disclosed filing facts and arithmetic aggregates, not a signal or verdict.

Track record

How ACM Research, Inc.’s moat rated in each of the years we can reconstruct from its filings — scored only on what was knowable at the time — and what its price and returns did afterward. The score never saw a price; the two are joined only in hindsight, for education, not as a signal.

Point-in-time scores 2017–2025, one methodology version · reconstructed from filings on file each Dec 31 — never with hindsight

Point-in-time Moat Score (dot colored by tier)Indexed price (total-return (dividends reinvested))Rated Wide-moat that year

How to read this: each dot is what the engine would have scored ACMR on that December 31; the line below is its total-return price path (dividends reinvested) in the years since.

0406080100WideNarrowShallowNo moatPoint-in-time Moat Score1002005001,0002,000Indexed price · log scale (2018 = 100)201720192021202320252026

Two tracks, one timeline: the score has its own 0–100 scale (top), the price its own 100-based scale (bottom) — never a shared axis. The price path is a total-return (dividends reinvested) index built from the same data the forward returns use; gaps in the score line are years with no reconstructed rating (see the table for why). The Table view carries every value.

What followed, in the years it rated Wide

In the 5 years ACMR rated Wide-moat (2020, 2021, 2022, 2023 and 2025), the median forward total return that followed — measured only after each year’s filings were public — was:

  • 1 year −8% vs the S&P 500’s 24% (price basis) · median over 4 years
  • 3 years −37% vs the S&P 500’s 28% (price basis) · median over 3 years
  • 5 years 50% vs the S&P 500’s 85% (price basis) · median over 1 year

These are medians computed from the data, not a claim about any one year. The company figures are total returns (dividends reinvested); the S&P 500 is the price-only ^GSPC index, which excludes dividends and so understates the index — the gap flatters the company. A quality rating is not a return forecast, and past returns don’t predict future ones. Educational only, not investment advice.

Does ACM Research, Inc. have an economic moat?
Based on its FY2025 SEC filings, the Moat Index scores ACM Research, Inc. (ACMR) 78.9 out of 100 — a Narrow moat. The five questions behind that score begin at 20% each; if exactly one genuinely lacks data, the other four weights are renormalized and disclosed. revenue and EPS trend 95, pricing power 78, returns on capital 70, balance-sheet safety 89, capital allocation 62.
How has ACMR's Moat Score changed over time?
The record logs 16 readings since Jul 17, 2026; the latest reads 78.9 out of 100 (narrow moat). No tier changes on record yet. (Methodology or normalizer upgrades on Jul 20, 2026, Jul 23, 2026, Jul 26, 2026 re-based the score; readings across versions aren't compared.) The history is append-only — readings are only ever added, never rewritten.
