MMM Ex-Dividend Date

As of Nov 2, 2026, MMM's next ex-dividend date hasn't been announced; the most recent was Aug 24, 2026. Based on its quarterly schedule, check back or watch the dividend calendar for the announcement.

The ex-dividend date is the cut-off for owning a stock in time to receive its next dividend. If you buy MMM on or after the ex-dividend date, the seller — not you — receives the upcoming payment. Buy before it and you're entitled to the dividend.

You must own MMM before the ex-dividend date — i.e. buy at least one trading day earlier. Since the move to T+1 settlement, the record date and ex-dividend date now fall on the same day, so the ex-date is the deadline that matters.

As of Nov 2, 2026, MMM's most recent dividend was $0.7800 per share, paid on a quarterly basis — about $3.12 per share annually, a forward yield of roughly 1.79%.
