Thermo Fisher (TMO) Sr. VP Lisa Britt Exercises Options & Sells 5,850

What Happened Lisa P. Britt, Senior Vice President and Chief Human Resources Officer of Thermo Fisher Scientific (TMO), exercised 5,850 stock options on 2026-08-06 at an exercise price of $309.63 (cost = $1,811,336) and sold the same 5,850 shares in an open-market sale that day at $580.00 per share for total proceeds of $3,393,000. The transactions resulted in roughly $1,581,664 of gross proceeds after subtracting the exercise cost (before taxes/fees). This is a cashless-exercise pattern (exercise followed by immediate sale), which is a routine monetization of vested options rather than a purchase of new stock.
