Mazzara Philip, General Counsel and Secretary of Astera Labs (ALAB), has filed 92 Form 4 transactions, all in that single company. The pattern is one-sided: no open-market purchases, no sales back to the issuer, and no gifts. The only cash events are open-market sales, totaling $16,251,821.37. The sole non-sale activity is $22,561.23 in acquisitions, which under SEC code "A" represents compensation grants, not discretionary buying.
The recent direction reinforces the selling bias. In the 25 most recent filings, every transaction is an open-market sale of ALAB stock. The heaviest cluster came on August 17, 2026, when 18 separate sales were recorded. Individual values on that date ranged from $15,492.52 to $451,942.80, with several trades above $200,000. The combined August 17 total exceeds $2.3 million. Earlier in the year, on May 18 and May 21, 2026, Mazzara filed seven additional sales, with values from $37,571.05 to $231,655.98.
The data shows a consistent seller. Over the entire filing history, Mazzara has converted no options (no "M" codes) and received only modest equity awards. The selling is concentrated in ALAB and has continued through 2026, with the largest dollar volume occurring in the most recent August filing window. There is no countervailing purchase activity in the record.
