A share price tends to move through four phases: moving sideways (stage 1), rising (stage 2), stalling near a high (stage 3) and falling (stage 4). Today Astera Labs, Inc. is in stage 1. The phase helps read everything below.

Over the past 13 weeks it has done worse than the S&P 500, and it has been behind for 12 weeks running.

Over the last 2.6 years the share price moved +220% while the S&P 500 moved +47%, so it is ahead of the index over that whole period. It was last ahead over 13 weeks in the week of 14 August 2026. The chart above shows the 13-week comparison for every week.

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

Astera Labs, 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.

Astera Labs is on 2 of our US lists: Nasdaq 100 companies and US tech stocks.

Astera Labs, Inc. earned $153 M of net profit in the Jun 2026 quarter, +198.9% on the same quarter a year earlier. That is the 3rd quarter in a row of profit growth. Full-year FY25 profit was $219 M. That is 39.0% of the quarter's revenue. The same quarter a year earlier earned $51.2 M.

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

4 of the last 12 reported quarters were loss-making.

Why profit moved: revenue changed +104.5% on a year earlier and the margin moved +2.0 percentage points. Most of the change came from keeping more of each sale.

On average over the last four quarters, profit changed +144.4% and revenue +98.4%. Profit is growing faster than sales: fixed costs are spread over more sales, so each extra dollar of revenue adds more to profit.

Astera Labs, Inc. reported $392 M of revenue in the Jun 2026 quarter, +104.5% on the same quarter a year earlier. That is the 12th quarter in a row with growth on the year before. Over 3 years it has grown 120.2% a year on average. The last full year, FY25, came in at $853 M.

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

The last four reported quarters add to $1.2 B.

FY25 revenue was $853 M, +115.1% on the year before.

Recent pace: the last four quarters grew +98.4% on average, against 120.2% 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 +98.5%, against +128.8% a year over the last 8 quarters (rolling over).

Astera Labs, Inc.'s operating margin was 22.7% in the Jun 2026 quarter, 2.0 percentage points higher than the same quarter a year ago. Across 4 years it has been between −75.4% and 20.3%. The latest quarter is above every full year in that period.

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 +2.0 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.

Astera Labs, Inc.'s cash-flow history is too short to judge how much of its profit turns into cash. In FY25 it brought in $319 M of operating cash against $219 M of profit. After $37.5 M of spending on assets, $282 M was left over as free cash.

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.

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

Astera Labs, 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 $74.6 M on assets over the last 3 years. Averaged over those years that is 2.9% 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: $74.6 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.

Astera Labs, Inc.'s P/E is 88.3×, with too little history to compare. 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.

In short: there is too little history to say whether the multiple is high or low for this company, so the earnings trend underneath matters more than the multiple.

Astera Labs, Inc.'s business trend cannot be read yet. There are fewer than eight usable quarters of growth figures, so there is not enough history to read the trend. This is based on 11 quarters of 2 measures, with some gaps.

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: with too little history, we say so rather than guess a direction.

One or more growth lines have an extreme jump caused by comparing with a near-zero or loss-making quarter. Those jumps are capped before reading and drawn at the edge of the chart, so one odd quarter does not decide the result.

There are fewer than eight usable quarters, so this page does not guess a direction from so little history.

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.

Astera Labs, Inc. earned a ROE of 16% in FY25. That is up from a low of −34% in FY22. Its return on capital used (ROIC) is 41.0 percentage points above its cost of capital, so growth here adds value, not just size. It comes from a 25.7% net margin and 0.56× 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 25.7% net margin × 0.56× asset turnover × 1.12× leverage (assets divided by equity) ≈ 16.1% on equity. The margin does most of the work; borrowing plays a small part, so this return is earned, not borrowed.

The key test, return on capital used minus the cost of capital: 66.4% − 25.4% = +41.0 percentage points. The 25.4% is an estimate of this company's own cost of capital. Read the sign and size of the gap, not the decimals. A gap this wide means each dollar put back into the business creates more than a dollar of value.

Astera Labs, Inc. has total debt of $44.4 M against shareholder equity of $1.7 B as of Jun 2026, so its debt is 0.03× its equity, which is very little. Year by year, that ratio went from 0.01 in FY22 to 0.02 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.

5.1% of Astera Labs, 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 1.9 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 Astera Labs, Inc., the Z-score is 79.02. 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 79.02 is well clear of the danger zone, so the balance sheet is not the risk here.

52.1 out of 100, rank 10 of 27 in Semiconductors, with 71% of the evidence available.

Astera Labs, Inc. scores 52.1 out of 100 against the 27 companies it is compared with in Semiconductors, ranking 10. Earnings are strong; relative strength in its sector is -7.2% and the one-year return is 35.2%.

The four parts add up to the total exactly: 25 + 13.1 + 8.8 + 5.2 = 52.1. This is the same number shown on the industry page; it is worked out once for the whole group and read here.

What would change it: The score would fall if profit growth turns negative or margins stop improving while the share price lags its sector.

Astera Labs ranks 10 of 27 Semiconductors companies on the 4-Factor Sector Score, with 52.1 out of 100.

Missing figures are not scored as bad. They lower the confidence and pull the final score toward the middle. Relative strength counts only when the company has a reading for this week; with no reading, that factor is left out and its 20 points are shared across the other three in proportion. PEG is not shown when the ratio cannot mean anything: the company must be making a profit, its price-to-earnings must be positive, and its three-year earnings growth must fall between 5% and 60%. Dividing a price multiple by a loss, or by growth measured off a tiny base, produces a number that looks precise and tells you nothing. Under relative strength, one mark per week shows the last 12 weeks: a mark is filled where the company led S&P 500 by 5% or more over the 13 weeks ending that week, which is the same test used everywhere on this site. Price stage places the company on the same six-step path the industry is placed on (basing, turning, breaking out, leader, fading, asleep), read from how many weeks running it has led S&P 500 and whether that lead is growing or shrinking. It describes where the share price stands, not the direction of earnings, and it is not a recommendation; it is left blank for a company whose weekly history is too short or too stale to read.

The figures in this ranking come from the industry comparison: results through the Sep 2026 quarter, and the P/E at that quarter's end. The sections above use the latest weekly price, so a P/E or return there can differ a little from the one here. The stage words in this ranking (such as losing its lead or breaking out) describe the lead over the index, not the price phase in the price section.
