Astera Labs Q3: Record Q2, Scorpio Ramp, But Valuation and Customer Concentration Loom
Record Q2 revenue and strong Q3 guidance Astera Labs reported record Q2 revenue of $392.4 million, up 104% from a year ago, and guided Q3 to about 40% growth. That shows demand for its AI data-center connectivity chips remains very strong, supporting the stock.
This is the core new financial result that drove the stock in Q3.
Scorpio switch ramp faster than expected The Scorpio switch product family ramped faster than expected and became Astera's biggest product line. This shows the company is winning more content in AI racks, which supports future sales growth.
It highlights a key new product success that drove investor optimism.
New products and partnerships expand growth story Astera launched Leo memory controllers, signed a deal with d-Matrix, and sold out AWS capacity through 2028. These moves reinforce its growth story and show customers are committing to its technology.
These new developments broaden the growth narrative beyond existing products.
Valuation and customer concentration risks The stock trades at 93 times forward earnings, and one customer made up over 70% of 2025 revenue. Competition is rising from Broadcom, Marvell, and a new Microchip–Micron partnership, so the price may already reflect all the good news.
This is the main counterweight that could pressure the stock despite strong results.
