3M Company stock (ISIN US88579Y1010) closed at USD 162.02 on September 14, 2026, down 1.79 percent from the previous close of USD 164.97. The move came as investors weighed turnaround progress against PFAS litigation and valuation concerns.

Turnaround meets legal risk

According to ad hoc news on September 16, 2026, GuruFocus said 3M is exceeding key turnaround objectives and that the shares traded at a trailing price-earnings ratio of 29.25, above the company's 5-year median of 17.04. The same report said a Connecticut federal judge allowed firefighters to proceed with a lawsuit against more than 20 companies, including 3M, over alleged PFAS exposure.

The valuation gap is the key point. A P/E of 29.25 against a 5-year median of 17.04 leaves the stock priced well above its own history while legal overhangs remain visible.

Q2 figures improve

According to StockTitan, 3M reported Q2 2026 net sales of USD 6.5 billion, up from USD 6.344 billion a year earlier, while net income attributable to 3M rose to USD 933 million from USD 723 million. Diluted EPS increased to USD 1.78 from USD 1.34, and operating income fell to USD 984 million from USD 1.14 billion.

That mix matters for investors. Revenue rose 2.5 percent year over year, EPS gained 32.8 percent, and the quarter ended with an operating margin pressure point because operating income declined even as sales and net income improved.

September outlook

According to ad hoc news, Zacks sees earnings of USD 2.40 per share for the September 2026 quarter, compared with USD 1.98 per share in the September 2024 quarter. The same source also cited Q2 fiscal 2026 sales of USD 6.5 billion and profit margin of 14.35 percent.

Price stays supported

As of September 14, 2026, 3M stock stood at USD 162.02 on the New York Stock Exchange, with a prior close of USD 164.97 and a 52-week low of USD 120.00. The shares were also well below the cited 52-week average level of USD 185.57.
