Why Is 3M CO (MMM) Stock Up Today?

3M Co (MMM) surged 9.46% to $174.16 in a single session, driven by the company’s stronger-than-expected Q2 2026 earnings and an upward revision to its full-year guidance. The stock opened with a 5.6% gap up and climbed further during the session as investors reacted to the improved outlook and positive operating results. The move reflects renewed confidence in the company’s turnaround strategy and momentum in key business segments.

What Happened

3M reported Q2 2026 adjusted earnings per share of $2.40, exceeding the estimated $2.25. The company also raised its full-year adjusted EPS guidance to a range of $8.80 to $8.95, up from the previous $8.50 to $8.70. This revision was driven by strong performance in safety and electronics divisions, as well as improved operating margins. The company now expects full-year adjusted operating cash flow between $5.8 billion and $6 billion. The CEO noted ongoing pressures in consumer electronics and automotive segments, while the CFO highlighted a $110 million negative impact from tariffs and stranded costs. Despite these challenges, the company’s operating margin came in at 24.9%, slightly above estimates.

The stock opened at $168.01 and reached an intraday high of $174.45 before closing at $174.10.
