Mazzara Philip 4

What Happened
Philip Mazzara, General Counsel and Secretary of Astera Labs, sold a total of 14,076 shares of ALAB on May 18, 2026 in a series of open-market transactions. The individual lots were sold at prices ranging roughly from $216.10 to $235.36, producing aggregate proceeds of about $3,262,540.

Context
Sell-to-cover transactions are routine administrative moves to satisfy tax obligations when RSUs vest; they are generally considered procedural rather than a signal about the insider’s view of the company. For retail investors, discretionary buys by insiders tend to be more informative than mandatory withholding sales. If you want the exact per-trade prices within each weighted-average lot, the filer has committed to provide that breakdown on request.
