3M's Dividend Boost: Is the Stock Still Undervalued?

3M (MMM) has announced its third-quarter 2026 dividend of $0.78 per share, payable on September 11 to shareholders of record on August 24. The company's latest dividend decision offers a fresh reference point for assessing the stock. As of now, 3M's share price trades at $179.37, with a 90-day share price return of 15.60% and a one-year total shareholder return of 16.68%. This indicates that recent momentum has been stronger than the longer-term five-year total shareholder return of 31.25%.

According to analysts, 3M is now trading modestly below both analyst targets and an estimated intrinsic value, even after a strong 90-day run. One narrative suggests that 3M's most followed fair value estimate places it at $181.85 with a 7.68% discount rate, slightly above the recent close of $179.37. This implies limited valuation slack.

Significant operational efficiency gains are driving structurally higher operating margins and earnings benefits for 3M. These improvements are expected to compound as further optimization and automation are rolled out company-wide. However, the company still faces meaningful PFAS litigation and ongoing macro softness in key end markets, which could pressure margins and challenge the current valuation narrative.
