Innospec (IOSP) Ex-Dividend Date & Pay Dates

Innospec (IOSP) pays its dividend twice a year, usually in May and November. The next payment is on Nov 25, 2026, to shareholders who own IOSP before the Nov 17, 2026 ex-dividend date.

IOSP's last 2 regular dividends were paid in May and November. Companies tend to keep the same months year after year, though the exact dates move by a few days.

As of Nov 5, 2026, the next IOSP ex-dividend date on record is Nov 17, 2026, with a pay date of Nov 25, 2026. To receive the dividend you must own IOSP shares before this date.

The ex-dividend date is the cut-off for owning a stock in time to receive its next dividend. If you buy IOSP 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 IOSP 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, IOSP's most recent dividend was $0.9200 per share, paid on a semiannual basis — about $1.88 per share annually, a forward yield of roughly 2.33%.
