The ex-dividend date is the cut-off for owning a stock in time to receive its next dividend. If you buy ATO 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 ATO 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, ATO's most recent dividend was $1.0000 per share, paid on a quarterly basis — about $4.00 per share annually, a forward yield of roughly 2.27%.
