Operating margin is operating income as a share of revenue. Free cash flow is cash from operations minus capital spending. Return on equity is net income as a share of shareholders' equity. Market cap is the last closing share price times the latest diluted share count, so it is approximate. P/E is the last close divided by diluted earnings per share over the last four quarters, or the latest fiscal year where the quarters aren't available; there is none when the company made a loss.

Valuation

Two ways to value Astera Labs yourself, both starting from its filings: a discounted cash flow model and the price-to-earnings method.

Discounted cash flow (DCF)

A discounted cash flow (DCF) model values a business as the cash it may generate in future, discounted back to today. The starting figures come from Astera Labs' 10-K (or, for net cash and shares, its latest 10-Q) and the assumptions are yours: start from one of three example scenarios, then change any figure to see what it implies for a share, and how that compares with the last share price.

The example scenarios need Astera Labs' net cash, which its filings' structured data doesn't give for its latest year. You can enter your own figure in the calculator.

From the filings

Starting free cash flow, US$ millions

Cash from operations minus depreciation in fiscal 2025: a rough guide to cash flow before spending to grow, for a company building heavily.

Net cash, US$ millions Cash and short-term investments minus debt and finance leases at December 31, 2025. Negative means net debt.

Diluted shares, millions

Weighted-average diluted shares in fiscal 2025.

Your assumptions

Start from

Fitted to Astera Labs's own revenue growth, as above. Cautious: growth of 10% then 6% a year, 2% after year 10, a 13% discount rate. Base: growth of 20% then 11% a year, 2.5% after year 10, a 12% discount rate. Optimistic: growth of 25% then 14% a year, 3% after year 10, a 11% discount rate.

Free cash flow growth, years 1 to 5 (% a year)

Free cash flow growth, years 6 to 10 (% a year)

Growth after year 10 (% a year)Long-run growth forever after year 10. Usually close to inflation, and always below the discount rate.

Discount rate (% a year)The yearly return an investor wants for the risk. A higher rate gives a lower value.

How the value changes with two assumptions

Value per share in US$, with the growth rates above. The highlighted cell matches the current assumptions.

How the model works. Free cash flow grows at the first rate for five years and the second rate for five more, and each year is discounted at the discount rate. Everything after year 10 is valued as year-10 cash flow × (1 + growth after year 10) ÷ (discount rate − growth after year 10), discounted back ten years. Net cash is added and the total is divided by diluted shares. The result depends entirely on the assumptions. It is not a forecast, a price target or a recommendation. The last close is the consolidated US closing price, from Databento.

Price-to-earnings (P/E) method

Another common way to value a company is to multiply its earnings per share by a price-to-earnings (P/E) multiple: the number of years of today's earnings an investor pays for a share. A higher multiple usually means investors expect earnings to grow. Choose a multiple, for example from similar companies, to see the value it gives.

Value per share on three example scenarios, from Astera Labs' earnings per share of $2.02 (over the last four quarters). Each grows earnings for a year at the cash flow scenarios' rates and applies a multiple to next year's earnings: 57.4×, the middle of Astera Labs' own P/E today, its peers' median and its sector's median (its peers' median) for the base scenario, 20% less and more for the cautious and optimistic ones. The price is brought back a year at 13%, 12% and 11%. Select one to load it into the calculator. These are the model's arithmetic on those assumptions, not a forecast or a price target.

Earnings per share, US$

Diluted earnings per share over the four quarters to June 30, 2026, from the 10-Qs and 10-K.

P/E multiple

P/E today is the last close divided by the latest earnings per share, the four quarters' where available. Peers: MACOM Technology Solutions, Rambus.

Earnings growth in the years ahead (% a year) Starts at Astera Labs' revenue growth over the last 3 years, 120.1% a year, kept between 0% and 20%, as the base scenario does.

Apply the multiple to earnings

A multiple on a future year's earnings gives the price then, brought back to today at the discount rate below.

Discount rate (% a year) The yearly return an investor wants for the risk, as in the cash flow model.

RambusRMBS	$90.32	$2.43	37.2×

How the P/E method works. Value per share is earnings per share times the multiple. On a future year's earnings, that gives the price in that year, which is brought back to today at the discount rate: price ÷ (1 + discount rate) for each year ahead. It is quick and easy to compare across companies, but it ignores debt and cash, and earnings can swing with one-off gains and charges, so a multiple says most about steady, profitable businesses. Like the cash flow model, the result depends entirely on the assumptions you choose. It is not a forecast, a price target or a recommendation.

US$ millions unless stated, at each fiscal year end. Net debt to EBITDA is debt minus cash, divided by operating income before depreciation and amortization: roughly how many years of those earnings the net debt equals. Debt to equity is debt as a multiple of shareholders' equity. Interest coverage is operating income divided by interest expense. The current ratio is current assets over current liabilities; the quick ratio leaves out inventory.

The latest 12 of 45 trades. Open-market purchases and sales by officers, directors and 10% owners, from their Form 4 filings with the SEC: one row per person, day and filing, at the day's average price. Grants, option exercises and shares withheld for tax aren't counted. Insiders buy and sell for many reasons, such as taxes, spreading their savings or a plan set up months earlier, so a trade on its own says little about where a company is heading.
