This page treats a rise as over when the price closes below its 200-day average on two Fridays in a row.

ACM Research, Inc. pays no dividend. In the last 12 reported quarters it declared no dividend per share, so there is no payout history to chart and no yield to show. Companies like this usually keep their earnings in the business, so the cash-flow sections show where that cash goes.

ACM Research is on one of our US lists: US tech stocks.

ACM Research, Inc. earned $89.0 M of net profit in the Jun 2026 quarter, +199.0% on the same quarter a year earlier. Full-year FY25 profit was $94.1 M. Over 4 years profit has grown 25.6% a year on average. That is 30.4% of the quarter's revenue. The same quarter a year earlier earned $29.8 M.

Net profit is what is left after every cost, interest and tax. Earnings per share, dividends and book value all grow from it.

For the full year, FY25 profit was $94.1 M (−9.2% on the year before).

Why profit moved: revenue changed +36.0% on a year earlier and the margin moved +2.3 percentage points. Most of the change came from keeping more of each sale.

On average over the last four quarters, profit changed +31.5% and revenue +27.9%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra dollar of revenue adds more to profit.

ACM Research, Inc. reported $293 M of revenue in the Jun 2026 quarter, +36.0% on the same quarter a year earlier. That is the 12th quarter in a row with growth on the year before. Over 4 years it has grown 36.5% a year on average. The last full year, FY25, came in at $901 M.

Revenue is everything the company billed its customers in the period.

The last four reported quarters add to $1.0 B.

FY25 revenue was $901 M, +15.2% on the year before.

Recent pace: the last four quarters grew +27.9% on average, against 36.5% a year over the longer run, so this year is growing slower than its own long-run rate.

Is growth speeding up? Revenue over the last 12 months grew +27.3%, against +22.3% a year over the last 8 quarters (accelerating); profit over the last 12 months grew +34.0%, against +32.9% a year (stabilising).

ACM Research, Inc.'s operating margin was 17.0% in the Jun 2026 quarter, 2.3 percentage points higher than the same quarter a year ago. Across 5 years it has been between 12.1% and 19.3%. The latest quarter is within that range.

Operating margin is what is left from every $100 of sales after the costs of running the business, before interest and tax. It shows pricing power and cost control.

Why the margin moved: operating margin changed +2.3 percentage points on the year while gross margin changed −2.5 points. So the gain came mostly from the gross margin, which means input costs and prices charged.

Over the last 3 years, 24% of ACM Research, Inc.'s reported profit came in as cash from its operations, a gap worth watching. In FY25 its operations used $10.3 M of cash, against $94.1 M of profit. After $56.3 M of spending on assets, free cash was −$66.6 M: it spent more than its operations brought in.

The profit and loss account shows what was earned. The cash-flow statement shows the cash that actually came in. Comparing operating cash flow with profit is one of the best checks that a profit is real.

Cash-flow figures here are yearly, because quarterly cash statements are not published, so this section changes once a year.

Why: the cash figure is clear, but the day counts behind it are not in our data, so we show it without guessing the reason.

What to look at next: the main use of cash is spending on assets. The next section checks what that spending is building.

ACM Research, Inc. does not report the customer, stock and supplier day counts a cash cycle needs, so this section looks at its spending on assets instead. It spent $201 M on assets over the last 3 years. Averaged over those years that is 7.4% of FY25 revenue a year.

Working capital is the cash tied up between paying suppliers and getting paid. Debtor days: how long customers take to pay. Inventory days: how long stock sits. The cash cycle: the whole loop, in days of sales.

Nothing is estimated in place of the missing day counts, so no cash-cycle chart is drawn.

Spending on assets: $201 M over the last 3 years.

In short: the cash is going into new capacity, not getting stuck in the daily cycle. The question is whether the new capacity earns.

ACM Research, Inc.'s P/E is 20.7×, in the middle of its own history: higher than 62% of past readings. Its usual P/E (the middle reading) is 17.9×, over 4.6 years of weekly prices. This compares the share price with the company’s own past. It does not say what the business is worth.

P/E is the share price divided by a year's profit per share: how many dollars the market pays for each dollar of yearly profit.

Why the multiple is where it is: over the past year earnings per share moved −10.6% while the price moved +42.9%. The price did better than earnings, which pushed the multiple up within its own range.

Where the price move came from: over 3 years the price moved +43.3% a year; about +24.5% a year came from earnings growth and about +18.8 percentage points from the multiple (the market paying more). The split is approximate (price return minus earnings growth). It shows how much of the move came from the market paying a different multiple.

In short: the multiple is about average against its own past, so the earnings trend underneath matters more than the multiple.

ACM Research, Inc.'s business is turning around. EPS growth has swung from −10.9% at its low to +26.8%, rising from a low 1 quarters ago, with ROCE falling at 6.6%. This is based on 12 quarters of 4 measures.

Every business is somewhere on a path of getting better or worse, and this section names where. The last 12 quarters of growth in revenue, profit and earnings per share, plus the return the business earns on its capital, are read as lines. Getting worse: the lines are falling. Turning around: a low point has just formed and the last few quarters are rising from it. Getting better: the rise from the low has lasted. Growing steadily: steady growth with healthy returns. Slowing from a peak: still high, but slowing. When the lines disagree the result is mixed; too little history means no reading. CAGR (compound annual growth rate) is the steady yearly rate that would turn the starting value into the latest one. It is the fairest way to compare growth over different periods. If the 1-year figure is much bigger than the 10-year one, recent growth is running faster than the long-run trend. A dash means there is no figure for that period, or the starting year was a loss, where a growth rate means nothing.

Why it matters: a turn in growth is often where a bigger change starts. The lines say a turn is forming, so the question is whether the next quarters confirm it.

The latest quarter’s profit includes a one-off item bigger than the normal business, so the profit line is shown but does not count in this reading.

Compound annual growth rate (%)

Compound annual growth rate over each period, %. Revenue, profit and EPS come from yearly figures; the stock price row is price growth over the same periods. A dash means no figure for that period, or the starting year was a loss.

ACM Research, Inc. earned a ROE of 5% in FY25. Its return on capital used (ROIC) is 5.1 percentage points below its cost of capital, so growth here does not yet pay for the capital it uses. It comes from a 10.4% net margin and 0.31× asset turnover (sales divided by assets).

Return on equity (ROE) is the profit the business earns on its shareholders’ money. We do not have the full capital split, so ROE is the longest history we can draw here.

Why the return is what it is (FY25): a 10.4% net margin × 0.31× asset turnover × 1.49× leverage (assets divided by equity) ≈ 4.8% on equity. The margin does its share; borrowing plays a small part, so this return is earned, not borrowed.

The key test, return on capital used minus the cost of capital: 9.9% − 15.0% = −5.1 percentage points. The 15.0% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. Negative: growth at these returns loses value until returns improve.

ACM Research, Inc. has total debt of $349 M against shareholder equity of $2.4 B as of Jun 2026, so its debt is 0.15× its equity, which is very little. Year by year, that ratio went from 0.05 in FY21 to 0.15 in FY25. So the returns on this page come from the business, not from borrowed money.

Debt-to-equity shows how much of the business is paid for with borrowed money. Lower is safer, and the direction matters as much as the level.

5.7% of ACM Research, Inc.'s tradable shares are in short positions, which are bets that the price will fall, so some traders are betting against it. At normal trading volumes, closing those positions would take about 2.6 days. US companies do not publish a quarter-by-quarter list of owners, so this page uses short interest instead.

There is no quarter-by-quarter list of owners here, so we look at short interest: the share of tradable shares held in short positions, which gain if the price falls.

It is a single reading at one point in time; we do not have its history.

Why it is at this level: the figure does not say who has the short positions or why, so we show the level without guessing the story.

For ACM Research, Inc., the Z-score is 3.27. A Z-score above about 3 is safe and below about 1.8 signals danger, so this is well clear of danger. It estimates how far the balance sheet is from trouble; it is not a forecast of failure.

The Z-score estimates how far a company is from balance-sheet trouble. Above about 3 is safe; below about 1.8 is the danger zone. It was built for manufacturers, so it is not used for banks and lenders.

Why it matters: a Z-score of 3.27 is well clear of the danger zone, so the balance sheet is not the risk here.
