    Astera Labs Chairman Disposes $51.3M in Stock via Pre-Arranged 10b5-1 Trading Plan

    Question

    Astera Labs Chairman Disposes $51.3M in Stock via Pre-Arranged 10b5-1 Trading Plan

    Direct answer

    Manuel Alba, Chairman of Astera Labs, liquidated 183,000 shares representing $51.3 million in proceeds on September 1 under a Rule 10b5-1 trading plan adopted in May. The planned sale locked in gains following a 54% year-over-year run-up driven by surging AI server connectivity demand. Despite the size of the trade, Alba retains 1.4 million shares, mitigating immediate corporate governance overhang. However, large insider realizations in high-multiple data center infrastructure suppliers often induce short-term consolidation across AI interconnect and optical connectivity equities.
