On August 6, 2026, Thermo Fisher Scientific Inc. Chairman & CEO Marc N. Casper exercised 10,000 stock options at $309.63 per share and received 10,000 common shares, then sold those 10,000 shares plus an additional 10,115 shares of directly held stock in a series of open-market transactions at weighted average prices between approximately $571.05 and $579.90 per share, generating total direct sale proceeds of roughly $11.7 million and reducing his direct holdings from 133,925.358 to 123,925.358 shares. In parallel, an affiliated entity, Floral Park Associates, Inc., for which Casper reports indirect ownership, sold an additional 5,000 shares in multiple trades at prices between roughly $571.00 and $580.01 per share, realizing about $2.9 million and lowering its holdings from 9,368 to 4,368 shares. All transactions were executed under a pre-arranged Rule 10b5-1 trading plan adopted on April 27, 2026. After these transactions, Casper continues to hold a substantial equity stake in Thermo Fisher, with his remaining directly held shares alone worth approximately $73 million at a reference price near the reported sale prices, and his option exercise appears to have been fully offset by immediate sales of the acquired shares.
