Astera Labs reported record fourth-quarter and full-year 2025 results, underscoring accelerating demand for rack-scale AI connectivity. Q4 revenue reached $270.6 million, up 17% quarter-over-quarter and 92% year-over-year, while full-year revenue climbed to $852.5 million, up 115% from 2024. GAAP gross margin held at 75.6% in Q4, with GAAP operating income of $67.0 million and GAAP EPS of $0.25. The company guided Q1 2026 revenue to $286 million–$297 million, signaling continued sequential growth.
The results reflect expanding hyperscaler deployments of Astera’s Intelligent Connectivity Platform, including the production ramp of its Scorpio X-Series Smart Fabric Switch for a lead AI platform. The company broadened the Scorpio roadmap to support higher radix configurations, platform-specific protocols, in-network computing, Hypercast technology, and optical connectivity. Astera targets the merchant scale-up switching market, which it estimates could reach $20 billion annually by 2030. In parallel, the company expanded its CXL portfolio with Leo Smart Memory Controllers, supporting up to 2TB per controller and enabling memory expansion in Microsoft Azure M-series virtual machines.
Astera also announced a CFO transition, with Desmond Lynch joining on March 2, 2026, succeeding Mike Tate, who moves into a strategic advisor role. The company opened a new design center in Israel to accelerate next-generation scale-up fabrics and address AI memory bottlenecks. Custom connectivity solutions, including support for NVLink Fusion architectures, aim to optimize heterogeneous AI infrastructure and improve energy efficiency across large-scale deployments.
• Q4 revenue: $270.6M (+17% QoQ, +92% YoY); FY2025 revenue: $852.5M (+115% YoY)
• Q4 GAAP gross margin: 75.6%; non-GAAP operating margin: 40.2%
• Scorpio X-Series production ramp for lead hyperscale AI platform
• Leo CXL Smart Memory Controllers: up to 2TB per controller; supports CXL 2.0 memory expansion in Azure

“Astera Labs delivered strong financial results in Q4 with revenue growing by 17% sequentially to a new record level of $270.6 million, highlighting a stellar 2025 with full-year revenue growth of 115% year-over-year,” said Jitendra Mohan, Chief Executive Officer.
🌐 Analysis: Astera’s momentum aligns with broader hyperscale investment in scale-up AI fabrics, where connectivity bandwidth and memory pooling have become critical constraints. As competitors such as Broadcom, Marvell, and Nvidia push deeper into custom and semi-custom AI interconnects, Astera’s expansion into switching silicon and CXL-based memory controllers positions it to capture a larger share of AI cluster architecture spend beyond traditional retimers.
