- About
- Astera Labs, Inc. makes semiconductor-based connectivity products for rack-scale AI infrastructure, from its base in San Jose, California. It sells four product families as chips, boards and modules: Scorpio fabric switches, Aries signal conditioners, Taurus Ethernet cable modules and Leo memory controllers, with software called COSMOS. Revenue grew from $396.3 million in 2024 to $852.5 million in 2025. It was $584.9 million in Q3 2026, up 154% from Q3 2025, and Scorpio became the largest product family. One customer made 53% of Q3 2026 revenue, and three customers each made 10% or more. Jitendra Mohan is Chief Executive Officer. The company had cash and marketable securities of $1.4 billion and no borrowings at September 30, 2026. The pick is the common stock on Nasdaq (ALAB), in US dollars.
- Thesis
- The market prices Astera Labs close to the AI estimate, as a young chip company that depends on a few large customers and a few AI server programs. One customer made 53% of Q3 2026 revenue. Revenue grew 154% in Q3 2026, and the company expects Q4 revenue of $730 million to $750 million, but the Scorpio switch ramp is new. Costs also grow: GAAP operating expenses were $243.7 million in Q3 and the company expects $273 million to $279 million in Q4, and share-based compensation was 14.1% of Q3 revenue. A customer holds warrants for up to 3,262,299 more shares at $142.82, which vest as that customer buys more. For the price to stay close to the AI estimate, Scorpio must keep ramping with more than one large customer, Aries 7 and the Leo memory products must turn design wins into revenue in 2027, and the gross margin must stay near 72%. The dated tests are Aries 7 sampling in Q4 2026, the Q4 report in February 2027 and the Orion rack designs, which the company expects to reach its OEM and ODM partners from Q1 2027. If revenue keeps growing and the customer base widens, the price can stay close to the AI estimate. If the main customer moves to its own chips or to a competitor's switch, the AI estimate would fall.
- Valuation
- The intrinsic value for Astera Labs is an AI estimate from November 12, 2026. It is not an analyst's value. An AI research agent calculated it from Astera Labs' filings with the SEC. The method is a multiple of 2027 GAAP net income per diluted share. GAAP net income is after share-based compensation, interest and tax, so the estimate makes no debt or cash adjustment. Astera Labs has no borrowings. The Q3 2026 release (8-K, November 3, 2026) gives revenue of $584.9 million, a GAAP gross margin of 72.3%, GAAP operating income of $179.1 million, GAAP net income of $182.9 million, which is $0.99 per diluted share on 184.1 million diluted shares, and share-based compensation of $82.6 million. Its outlook for Q4 gives revenue of $730 million to $750 million, a GAAP gross margin of about 72%, GAAP operating expenses of $273 million to $279 million, a GAAP tax rate of about 20% and GAAP diluted net income per share of $1.13 to $1.17 on about 187 million diluted shares. The Form 10-Q for the quarter ended September 30, 2026 gives 174,782,075 shares at October 31, 2026, cash and marketable securities of $1,378.2 million, one customer at 53% of Q3 revenue and warrants held by a customer for up to 3,262,299 shares at $142.82. The 2027 figures and the multiples are assumptions. The estimate takes 190 million diluted shares and a tax rate of 20%. The midpoint of the Q4 revenue outlook is $740 million, which is $2,960 million for a year. The low case assumes that the large customer buys less and prices fall, with revenue of $2,600 million, a GAAP gross margin of 68%, operating expenses of $1,250 million and interest income of $50 million. This gives operating income of $518 million, net income of $454.4 million and $2.39 per share, at 30 times. It gives $71.70 per share. The base case assumes that Scorpio and Aries keep growing, with revenue of $4,000 million, a gross margin of 72%, operating expenses of $1,300 million and interest income of $60 million. This gives operating income of $1,580 million, net income of $1,312 million and $6.91 per share, at 35 times. It gives $241.85 per share. The high case assumes that new products add to the ramp, with revenue of $5,200 million, a gross margin of 73%, operating expenses of $1,450 million and interest income of $70 million. This gives operating income of $2,346 million, net income of $1,932.8 million and $10.17 per share, at 40 times. It gives $406.80 per share. The estimate assumes weights of 25%, 50% and 25%. The weighted intrinsic value is $240.55 per share.
As of Nov 12, 2026.
- Risks
- Customer concentration. One customer made 53% of Q3 2026 revenue, and three customers each made 10% or more. Some are manufacturing partners that buy for end customers, so a shift of volume between them can move revenue fast.
AI spending cycle. Demand depends on spending by cloud companies on AI data centers. A pause in that spending would cut orders quickly.
Competition and product timing. The semiconductor industry is competitive and cyclical. New products such as Aries 7, Leo X and Orion must pass customer qualification, and delays would move revenue to later periods.
Margin pressure. The GAAP gross margin was 72.3% in Q3 2026, against 76.2% a year earlier, as the mix moved to switches and boards. A further fall in margin would cut profit.
Dilution. Share-based compensation was $195.5 million in the first nine months of 2026, and warrants for a customer can add up to 3,262,299 shares at $142.82. Diluted shares were 184.1 million in Q3 2026, against 174.1 million basic.
Trade rules. Tariffs, export limits and other trade rules can raise costs or delay shipments of its products.

- Checkpoints
- Feb 9, 2027 (estimate): Q4 2026 results: revenue and Q1 outlook. Pending. Watch: Q4 revenue of $730 million or more and a Q1 2027 outlook above it pass; lower revenue or a lower outlook fails.
Q1 2027 (estimate): Orion rack designs reach partners. Pending. Watch: Orion reference and system designs available through OEM and ODM partners in Q1 2027 pass; a later date fails.
