Post-it Maker, AI Supplier? 3M Stock Jumps 5.8% on Amazon Data Centre Deal and a Raised Outlook

The direct answer

3M shares jumped 5.78% on Tuesday, October 20, 2026, closing at $171.37 after the industrial company beat third-quarter profit forecasts, raised its full-year earnings outlook for the third straight quarter, and expanded a data centre partnership with Amazon. The deal gives Amazon a warrant to buy up to 3.2 million 3M shares, tied to $6 billion in cumulative purchases of 3M optical connectivity and other data centre products over seven years.

What happened

3M reported adjusted earnings of $2.50 per share for the third quarter, up 12% from a year earlier and ahead of analyst forecasts of about $2.38 to $2.39 per share. Adjusted sales rose 4.2% to $6.6 billion, with adjusted organic sales growth of 3.3%. Adjusted operating margin expanded to 26.2%.

On the back of that quarter, 3M raised its full-year 2026 adjusted earnings guidance to $9.10 to $9.15 per share, up from its previous forecast of $8.80 to $8.95. That is the third consecutive quarterly raise: the midpoint was $8.60 in the first quarter and $8.88 in the second, according to Motley Fool coverage of the results.

The Amazon news landed separately on Monday evening in a securities filing. 3M is expanding its commercial relationship with Amazon to deploy and scale optical connectivity and other data centre products. Amazon received warrants for 3.2 million 3M shares, which vest after it spends $6 billion on those products. 3M has also taken a 4.7% stake in fibre-optics partner Genius Electronic Optical.

Why it's blowing up

First, the headline surprise is who 3M is in this story. This is the company best known for Post-it Notes and Scotch tape. On Tuesday, investors were pricing it — at least in part — as an AI infrastructure supplier. Optical connectivity products move data between server racks using light over fibre, a growing need as technology giants build larger data centres for artificial intelligence. Coverage from Reuters noted that growth tied to data centres and semiconductor-related markets helped cushion weaker demand from automotive and consumer electronics customers.

Second, the warrant structure makes the deal hard to ignore. If Amazon hits the $6 billion purchasing milestone over seven years, it can end up owning a small piece of 3M itself — an unusual alignment for a supplier agreement, and the detail spreading fastest in coverage.

Third, the earnings beat was broad enough to support the story. Reuters reported that cost controls and higher prices supported margins, that the safety and industrial business remained resilient, and that 3M launched 87 new products in the third quarter, with a target of more than 350 launches by the end of the year.
