Why is Thermo Fisher Scientific, Inc. (TMO) stock moving?

Thermo Fisher reported Q3 2026 revenue up 9% to $12.14B, with 6% organic growth and adjusted EPS up 15% to $6.68, and management said it is well positioned for an excellent 2026. The board then authorized a new $5B buyback replacing the prior program and declared a $0.47 quarterly dividend. Shares closed at $676.94 on Nov 5 and rose to $721.63 on Nov 9 on above-average volume, then ended at $718.20 on Nov 10, near the top of the 30-day range (about $661.6 to $723.1). Analyst views are split: Argus kept its Buy with a $780 target, while Evercore ISI cut its target from $720 to $615. Executive news is routine (EVP Michael Shafer retiring at year-end, a CHRO share sale), and the Optis FIB-SEM installations are incremental. Capital returns and solid Q3 results support the stock, but the rally has brought it close to recent highs and the analyst targets diverge widely.
