MMM — Q3 2026 Financial Report Analysis

Overview

3M's third-quarter GAAP earnings per share (EPS) jumped 70% to $2.63, but most of that jump came from the rising share price of Solventum, the healthcare company 3M spun off in 2024 and still owns about 15% of. That stake gained $281 million in value this quarter, after losing $94 million in the same quarter last year. Without that gain and 3M's other one-off items, adjusted EPS was $2.50, up 12% from $2.23. The operating business did improve. Adjusted sales, which leave out the PFAS chemicals 3M stopped making at the end of 2025, rose 4.2%. Organic growth (sales growth with currency moves, acquisitions and divestitures stripped out) was 3.3%, slower than the 5.4% we reported for the second quarter. Nearly all of the growth came from one segment, Safety and Industrial. Transportation and Electronics barely grew, and Consumer shrank slightly. 3M raised its full-year adjusted EPS guidance to $9.10–$9.15, but part of that increase comes from changing what it counts as "adjusted" (see below).

Key Financial Metrics

Operating margin is the share of sales left after paying to make, sell and develop products, before interest and tax. "Adjusted" figures are 3M's own non-GAAP numbers. They leave out what the company calls special items: litigation and PFAS-exit costs, the change in value of the Solventum stake, amortization and acquisition costs, transformation (restructuring) costs, divestiture losses, and sales and profit from the PFAS products it has exited. Starting this quarter, 3M also counts amortization of acquired intangible assets as a special item, and it restated past periods the same way. The company says this adds about 40 basis points (0.4 percentage points) to the Q3 adjusted operating margin and about $0.04 to adjusted EPS. Year-on-year comparisons are not materially affected. The quarter's $2.50 is on this new basis, so it is not directly comparable with the $2.40 Q2 figure in our earlier report.

Takeaway: The 70% GAAP EPS jump comes mainly from the market value of 3M's Solventum shares, not from its factories. The underlying result is adjusted EPS up 12%, of which about a quarter came from buybacks. That rests almost entirely on one segment, Safety and Industrial, while organic growth slowed from 5.4% in Q2 to 3.3% and Transportation and Electronics stalled at 0.5%.

Segment Performance

Safety and Industrial sales rose 9.1%. That includes 3.1 points from the July acquisition of Madison Fire & Rescue (about $90 million of sales, with operating income the filing calls "not significant") and a 1.2-point drag from businesses sold. Organic sales grew in electrical markets, fire safety, industrial adhesives and tapes, personal safety, automotive aftermarket, abrasives and industrial specialties. They fell in roofing granules. 3M credits growth and "net productivity" for the margin gain, partly offset by growth investment and the extra costs of losing shared PFAS operations ("cost dis-synergies").

Transportation and Electronics is where growth faded. Organic sales rose only 0.5%, compared with 5.9% in Q2 by our earlier report. Gains in semiconductor, aerospace, data center, advanced materials and commercial branding were offset by weakness in consumer electronics and auto. Operating income fell 3.4%, and the margin dropped 0.9 points on growth investment and dis-synergies.

Consumer organic sales fell 0.2%. 3M says lower inventory levels at U.S. retailers "more than offset positive POS and share gains." In other words, sales to shoppers at the checkout (point of sale) were up, but stores bought less from 3M to restock. The margin still improved on productivity.

By region, GAAP organic sales rose 4.4% in the Americas but fell 6.2% in Asia Pacific and 2.8% in Europe, the Middle East and Africa. These regional figures still include the exited PFAS products, so part of those declines may reflect the planned exit rather than weaker demand.

What the headline numbers hide

• The Solventum swing drives GAAP EPS. The stake's $281 million gain sits in "other expense (income)." It took that line from a $300 million expense a year ago to $112 million of income. 3M's effective tax rate also fell to 15.7% from 26.8%, which the MD&A puts mainly down to the tax effects of the Solventum stake and of litigation costs. GAAP operating income, which is unaffected by either, rose a more modest 7.7%.
• Buybacks did some of the work. Adjusted operating income rose 8.9% and adjusted net income 9.0%, but adjusted EPS rose 12.1% because the diluted share count fell 2.9%. Tax did not help on an adjusted basis: the adjusted tax rate rose to 21.1% from 19.9%. Buybacks have also slowed. 3M bought only about 1.3 million shares in Q3, at an average of $180.34 (roughly $230 million), against $3.2 billion for the first nine months. About $1.5 billion of its $7.5 billion authorization is left.
• Cash conversion is weak on a GAAP basis. Nine-month operating cash flow was $2,046 million, compared with $3,007 million of net income. The gap is mostly litigation payments: 3M's PFAS environmental liability is $7.5 billion, and the portion due within 12 months jumped to $2.8 billion from $0.7 billion at year-end. On 3M's adjusted basis, nine-month free cash flow was $3,086 million, about 83% of adjusted net income of $3,739 million, and roughly flat on last year's $3,083 million.
• Working capital is building. Inventories rose to $4,081 million from $3,661 million at year-end (+11.5%), and receivables rose to $4,116 million from $3,533 million (+16.5%), while nine-month sales grew 1.6%. Part of this is Madison, which added both. Still, the cash-flow statement, which excludes balances that came with acquisitions, shows a $344 million inventory build this year compared with $92 million a year ago.
• "One-off" costs that keep recurring. Transformation costs were $58 million this quarter and $224 million in the year to date. They are why SG&A (selling, general and administrative expenses) rose to 14.0% of sales from 12.5%. Amortization and acquisition-related items took $0.20 off EPS. That is more than the $64 million pre-tax charge alone would suggest, because it also includes accounting adjustments to Bain's minority stake in the new fire-safety venture.
• Insurance is offsetting litigation costs. 3M booked $221 million of insurance recoveries on respirator/asbestos, earplug and PFAS matters this quarter ($511 million year to date), compared with $182 million a year ago. That lowers reported net litigation costs, but the cash payments go on.

Litigation and Portfolio Updates

• PFAS (the "forever chemicals"): New Jersey's settlement of up to $450 million received final court approval in August 2026, and the appeal window has passed. Under the public water supplier (PWS) settlement, which totals $10.5–$12.5 billion, class members had to submit their PFAS testing results by the end of July 2026. The claims administrator is now reviewing them, and that review will help decide where in the range 3M's final bill falls. Eighteen PFAS actions are pending in Canada.
• Combat Arms earplugs: the accrued liability fell to $1.1 billion from $2.4 billion at year-end as 3M made settlement payments.
• Watson Grinding (Texas explosion): a July 2026 jury found 3M partly liable, the third such verdict out of four trials. 3M has recorded no liability, saying a loss is not probable or estimable.
• Madison Fire & Rescue: bought in July for $1.9 billion through a venture with Bain Capital. Bain contributed about $1.3 billion in cash, the venture borrowed $1.43 billion under a term loan, and 3M put in its breathing-apparatus (SCBA) business. 3M holds 50.1% of the voting interest and consolidates the venture, which is why income attributable to minority owners rose to $37 million from $7 million. Total debt rose to about $15.0 billion from $12.6 billion at year-end, also because of a €1.5 billion bond issue in September.
• Amazon: 3M expanded its data-center optical-connectivity relationship with Amazon. It issued Amazon a warrant to buy up to 3.2 million 3M shares, tied to $6 billion of cumulative sales of those products over seven years and other milestones.

Did last time's read hold up?

Our Q2 report highlighted guidance of above 3.5% adjusted organic growth and named Consumer as the one segment that was actually shrinking. Consumer stayed weak (-0.2% organic). But growth slowed across the company: adjusted organic growth fell from 5.4% in Q2 to 3.3% in Q3, leaving the year to date at 3.3%, below the full-year goal. That Q2 guidance excluded Madison. The new guidance includes it.

Guidance and Outlook

3M now guides for full-year 2026 adjusted total sales growth of more than 4.5%, adjusted organic growth of more than 3.5% (unchanged), adjusted EPS of $9.10–$9.15 (previously $8.80–$8.95), and adjusted free cash flow of about $4.8 billion. The new EPS range includes Madison and the new treatment of amortization. 3M quantified the amortization effect only for Q3 (about $0.04). If the other quarters are similar, roughly $0.16 of the $0.25 increase at the midpoint is the accounting change rather than better operations. That is our estimate; 3M has not published the full-year figure.

Holding organic growth above 3.5% for the year after 3.3% through September means Q4 has to come in at roughly 4% or better, while Transportation and Electronics grew 0.5% in Q3 and U.S. retailers are cutting inventory. The things to watch next quarter are whether consumer-electronics and auto demand stabilizes in Transportation and Electronics, whether Safety and Industrial can hold a margin near 30%, and the size of the PWS settlement payments now that the testing results are in.
