Stock Splits in September 2026

How to read this calendar

Every date on this page comes from one of two places, and the last column of each row says which. An exchange-calendar date is the effective date carried in the corporate-action feed the exchanges publish, and it is the date the split actually executes unless the company moves it. A company-announcement date is the one the issuer stated in its own 8-K, 6-K or press release, listed here before the exchange feed carries it, which is usually a matter of days.

The ratio reads new:old, so a 1:30 row means 30 old shares become 1 new share and the price moves the other way by the same factor. Forward splits lower the price and raise the share count, and companies tend to run them after a long move up. Reverse splits do the opposite, and a small company doing one is often working to stay above the minimum price its exchange requires. A row can also arrive dated with no ratio at all, because the announcement named a date and left the ratio for later; we would rather show the date we have than guess the rest of it.

Dates change. A company can move an execution date after announcing it, and the exchange feed can revise a ratio, so anything on this page more than a few days out is a plan rather than a settled fact.
