Astera Labs shares rise 18.65% after hours following Scorpio X-Series AI infrastructure enhancements and strategic AI product lineup.

Astera Labs, Inc. (ALAB) surged 18.65% in after-hours trading, driven by the announcement of major upgrades to its Scorpio X-Series for AI infrastructure and hyperscale data centers. The product enhancements, including higher radix support, in-network computing, and hyperscaler-specific optical connectivity, reinforced the company’s position in the AI connectivity market. These developments, coupled with anticipation of the February 10 Q4 earnings report (forecasting $245–253 million in revenue), signaled strong growth potential amid rising AI infrastructure demand. The move aligns with recent institutional buying and a "Moderate Buy" analyst rating, as investors bet on sustained momentum from product innovation and sector tailwinds.
