Astera Labs Rises 1.8% Premarket as Revenue Surges 154% and Q4 Outlook Accelerates
Astera Labs (NASDAQ: ALAB) shares rose about 1.8% in premarket trading after the company reported record third-quarter revenue, strong profitability and a fourth-quarter outlook pointing to another sharp sequential increase in sales.
Third-quarter revenue reached $584.9 million, up 154% year over year and 49% from the previous quarter. GAAP operating income was $179.1 million, while non-GAAP operating income reached $261.6 million, representing a 44.7% non-GAAP operating margin.
Non-GAAP diluted EPS came in at $1.32, while GAAP diluted EPS was $0.99. Gross margins remained exceptionally high, with both GAAP and non-GAAP gross margin above 72%.
The main growth driver was the Scorpio fabric switch family, which moved into high-volume production and became Astera Labs’ largest product line by revenue. The company also reported accelerating design activity across multiple customers and expanded its portfolio with new Aries, Leo and Orion products targeting AI connectivity, memory expansion and rack-scale infrastructure.
Astera Labs continues to position itself around the rapid expansion of AI infrastructure. Its Orion reference architecture is designed for rack-scale inference systems, while the new Leo memory products and Scorpio switches aim to increase memory bandwidth, accelerator utilization and overall system performance.
For the fourth quarter, Astera Labs expects revenue of $730 million to $750 million. At the midpoint, that would represent roughly 27% sequential growth from Q3. Non-GAAP diluted EPS is expected between $1.62 and $1.66, with gross margin projected at about 72%.
The 1.8% premarket gain appears to reflect confidence in Astera Labs’ rapid AI-driven growth and strong Q4 outlook. The relatively modest share reaction compared with the scale of the revenue increase may also suggest that investors had already priced in substantial growth expectations following the company’s recent expansion in AI infrastructure.
