MLM's last 4 regular dividends were paid in March, June, September and December. Companies tend to keep the same months year after year, though the exact dates move by a few days.

The ex-dividend date is the cut-off for owning a stock in time to receive its next dividend. If you buy MLM 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 MLM 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 5, 2026, MLM's most recent dividend was $0.8400 per share, paid on a quarterly basis — about $3.36 per share annually, a forward yield of roughly 0.60%.
