Michael Thomas Henderson is a declared insider at 2 companies; the most frequent names are Apogee Therapeutics, Inc. and Spyre Therapeutics, Inc. We count 35 filings; the first trade dates from 5 July 2024 and the latest from 3 September 2026.
Every open-market trade on record is a sale: 29 sales worth €16.8M. The totals exclude 8 filings filed without an amount. The rest of the record consists of 2 option exercises. In 2026 alone, the filings show no purchases and 17 sales.
The record was last updated on 3 September 2026 with a transaction in Apogee Therapeutics, Inc. The median gap between a trade and its publication by SEC (Form 4) is 2 days. For comparison, the SEC allows two business days to file a Form 4. Keep in mind that insiders sell for many reasons unrelated to the outlook, from tax bills to estate planning. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
