3M posts Q3 2026 profit surge and lifts full‑year adjusted EPS outlook

3M reported third‑quarter 2026 adjusted earnings per share of $2.50, a 12% year‑over‑year increase, on sales of $6.6 billion, up 1%. The company raised its full‑year 2026 adjusted EPS guidance to a range of $9.10‑$9.15. It also announced an expanded data‑center partnership with Amazon, issuing a warrant for up to 3.2 million shares tied to $6 billion of cumulative sales, and a strategic investment of roughly 4.7% in Genius Electronic Optical Co. (GSEO).

The higher EPS guidance signals stronger profitability expectations for 2026, which may support a higher valuation for MMM shares (the company expects adjusted EPS of $9.10‑$9.15). The Amazon warrant and GSEO stake could drive future revenue growth in the data‑center optics market.
