Here’s the thing about 3M. The market still prices it like a Post-it note company with legal problems. That framing is increasingly hard to defend.

3M reports Q2 2026 results Tuesday, July 21, before the market opens. And heading into the release, something shifted last week that deserves more attention than it got.

On July 15, 2026, 3M and Microsoft announced a strategic partnership focused on AI data center infrastructure and enterprise transformation. The headline sounds corporate. What it actually means is more specific: Microsoft’s Azure Cloud and AI Infrastructure will become the first announced hyperscale cloud provider to deploy 3M’s Expanded Beam Optical (EBO) technology.

For months, 3M had been referencing a significant hyperscaler order for EBO without naming the customer. Now we have a name. That matters. A named Microsoft commitment functions as a public proof of concept for every other hyperscaler building out AI infrastructure at scale.

What EBO Actually Is

EBO uses an expanded beam optical interface instead of the direct contact required in traditional connectors, making fiber connections faster to install, more tolerant of contamination and easier to maintain. In a data center where thousands of connections are being made and adjusted constantly, that is not a small operational difference.

The technology helps reduce the need for frequent cleaning and inspection while supporting reliable optical performance in dense, high-volume environments. Microsoft’s early use has shown the potential to reduce network deployment timelines in certain environments, and the technology has demonstrated strong signal performance in live data center conditions, where dust exposure and routine handling are inherent to installation and maintenance.

3M has been scaling production of EBO to meet accelerating demand and helped establish an industry Multi-Source Agreement to support standardization — the kind of structural move a company makes when it expects a technology to become a standard, not a niche product.

Slight tangent, but it matters: 3M will also adopt Microsoft’s AI and digital platforms across functions such as customer service, finance, sales and marketing, including AI agent-driven workflows for order management and credit assessment. This is a two-way commercial relationship, which is structurally more durable than a one-time supply agreement.

The Numbers Going Into Tuesday

Early consensus expects adjusted EPS of $2.27 and revenue of $6.38 billion. The company has beaten Wall Street’s EPS estimates in each of its last four consecutive quarters, which makes the streak worth watching.

In Q1, 3M delivered adjusted EPS of $2.14 on revenue of $6.03 billion, up 4.3% year over year. Adjusted operating margin improved to 23.8% from 23.5% a year earlier. The softer figure was organic growth, which came in at 1.2% and missed expectations. Management guided Q2 organic growth above 3%, with operating margin approaching 24.5%. Full-year guidance was reiterated at approximately 3% organic sales growth and adjusted EPS of $8.50 to $8.70, with free cash flow conversion above 100%.

The internal data center segment brings in approximately $100 million per year. That is the number investors should track from here. The potential market is significantly greater — CEO Bill Brown has described the optical interconnect opportunity as a multi-billion-dollar market.

Analyst Positioning

• JPMorgan analyst Chigusa Katoku upgraded 3M to Overweight from Neutral with a price target of $180, up from $178, ahead of the Q2 report.
• Goldman Sachs hiked its target to $190, up roughly 19% from current levels.
• Wolfe Research raised its price target to $189 from $182 and keeps an Outperform rating on the shares.
• Bernstein analyst Varun Govindaraj initiated coverage with an Underperform rating and a $131 price target.

The Bull and Bear of It

The bull case rests on three things: EBO is still in early commercial innings, the Azure win opens conversations with every other major hyperscaler, and the underlying industrial business is genuinely improving. Margins are expanding, new product launches are accelerating, and CEO Bill Brown has been simplifying the portfolio — including a fire and safety joint venture with Bain Capital announced this year that management said will create an approximately $800 million revenue business.

The bear case is harder to dismiss. Australia’s government launched legal action against 3M over contamination from firefighting foam containing PFAS. New York Attorney General Letitia James also sued 3M as part of PFAS-related proceedings. The liability tail is long and difficult to put a precise number on. And even in an optimistic scenario, the data center optics revenue is still a small fraction of a roughly $24 billion company — it takes time to move the consolidated results.

What to Watch Tuesday Morning

Organic growth is the swing factor. Management guided above 3% for Q2. If they hit it, the business acceleration story gets real traction. If they miss again on that specific metric, the Azure news will not be enough to hold the optimism near term.

• Q2 organic growth vs. the 3%-plus guidance target
• Any updated commentary on EBO order flow and capacity timelines
• Data center and power segment revenue vs. the roughly $600 million annual run rate
• Full-year EPS guidance confirmation in the $8.50 to $8.70 range
• PFAS litigation updates and any new settlement disclosures

What’s interesting is how the investment question has quietly shifted. This is no longer a story about whether 3M can stabilize. It’s about whether an industrial company that most people associate with office supplies has quietly put itself inside the physical backbone of AI infrastructure. Tuesday’s results will either give that argument legs or take them away.
