William Snider (board member) discloses dealings in 2 companies, chiefly Harvard Bioscience Inc and Telesis Bio Inc. In total, 4 filings cover trades dated from 22 June 2021 to 16 March 2026.
Every open-market trade on record is a purchase: 1 purchase worth €55k, and no sale. Buying on the open market means paying the going price with one's own funds, a different act from receiving shares as pay. Besides market trades, the filings include 2 share grants. Since January 2026: 1 purchase and no sales on the market.
Most recently, on 18 March 2026, the filings show an open-market purchase worth €55k in Harvard Bioscience Inc. The median gap between a trade and its publication by SEC (Form 4) is 3 days. The legal deadline for a Form 4 is two business days after the transaction. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
