Mathew Aby J.

Aby J. Mathew, an insider at BioLife Solutions (BLFS), has filed 308 Form 4 transactions at the company since 2014, with a lifetime total of 732,710 shares sold against just 8,600 bought. Buried in that total is a striking shift in behavior: from January 2025 through December 2025, Mathew sold roughly 400-650 shares on the open market in nearly every calendar month — a highly regular cadence consistent with an automatic 10b5-1 trading plan — at prices ranging from $20.11 to $27.36 per share. That monthly rhythm has since gone silent: his four most recent transactions, dated 2026-04-08, 2026-06-08, 2026-06-18 and 2026-07-07, are all coded 'F' — shares withheld to cover tax obligations on vesting equity, not open-market sales — with no accompanying sale in any of those months. After roughly fourteen consecutive months of regular selling, Mathew has stopped converting his vesting shares into cash for at least the last three months on record.
