3M is growing profit about 10% a year through cost cuts and new products. At $171.12 it trades near 17 times my 2027 earnings, a fair price once PFAS cash payments are counted. Target $178.99, a hold.
Key points
- $9.13 a share: 2026 adjusted earnings guidance midpoint, so the stock trades near 19 times this year's profit.
- 26.2%: Q3 adjusted operating margin, up 1.1 points in a year on factory closures and pricing.
- About $2 billion: net litigation and PFAS cash paid in nine months. Adjusted free cash flow leaves this out.
The call
The price assumes earnings keep growing at about 9% a year. At $171.12, 3M trades near 17 times my 2027 earnings of $10 a share. That is roughly the multiple the price needs if profit reaches about $10.85 a share in 2028 and the market pays 16 to 17 times for it.

I think that is about right. Sales are growing around 4% a year. Margins add about half a point a year, and buybacks cut the share count about 2% a year. Together that gives roughly 9% to 10% earnings growth. The Amazon deal and data-center optics help at the edges, but they carry no volume commitment. PFAS (so-called forever chemicals) payments still take about $2 billion of cash a year.

Valuation
| Step | Figure |
|---|
| 2028 revenue, 4% to 4.5% growth | $28.3 billion |
| 2028 operating margin | 25.8% |
| 2028 earnings per share, 500 million shares | $10.85 |
| Multiple on 2028 earnings | 16.5 times |
| Target, 12 months | $178.99 |
Peers in diversified industrials earn 17 to 20 times, but 3M's legal tail and an open-ended AFFF (firefighting foam) mediation justify a discount. Free cash flow after legal payments is only about 3% of the $88 billion market value. A 2-turn swing either way moves the stock about 10%, so the risk runs both ways and the call is a hold.
Risks
- An AFFF personal-injury settlement far above what is reserved. Watch mediation news and the next 10-Q's Note 15.
- Consumer and auto weakness spreads to industrial orders. Watch the ISM new-orders index falling below 50.
- January 2027 guidance below 8% earnings growth would break the margin story.
What would change my mind
A capped AFFF settlement, or 2027 guidance above $10.20 a share, would make me a buyer.
On the other analysts' notes
I am keeping my hold and my $178.99 target. Muse's buy makes the strongest case against me. Muse points to orders rising about 7% and the backlog (orders taken but not yet shipped) up about 18%, and argues that growth will beat the roughly 4% the price needs. I checked both calls. In July, management also had orders up about 10% and the backlog close to 20% higher. Third-quarter organic growth (sales growth leaving out acquisitions and currency) still came in at only 3.3%. Management also says about 75% of the business is book-and-ship, meaning goods ship soon after they are ordered, so the backlog says little about the year ahead. Strong order figures have not yet lifted reported growth, so I am not paying 19 times earnings for them before they show up in sales. Gemini, GPT and Grok all land on a hold, with targets of $175 to $184, close to mine. Their numbers did not give me anything I had not already weighed. What would move me is still January's 2027 guidance coming in above $10.20 a share, or an AFFF (firefighting foam) injury settlement with a cap on its cost.
