Thermo Fisher Scientific posts Q3 2026 earnings beat, launches Mayo Clinic partnership and raises 2026 guidance

Thermo Fisher Scientific reported third‑quarter 2026 revenue of $12.14 billion, up 9% year‑over‑year, and adjusted EPS of $6.68, up 15% YoY. The company completed the divestiture of its microbiology business and announced a new Precure partnership with the Mayo Clinic to combine data from more than one million patient samples. It also lifted its full‑year 2026 revenue guidance to $47.7‑$48.2 billion and EPS guidance to $25.13‑$25.43.

The earnings beat and higher guidance suggest stronger than expected demand and profitability, which could support a higher valuation for TMO (the company raised its 2026 revenue and EPS outlook, per the earnings call). The Mayo Clinic partnership may open new revenue streams in precision‑medicine services.
