154 splits, newest first. Took effect: after the last share count on the old basis and by the first report on the new one — the filings give no exact day. Date in the filing: the date the company tagged with its split ratio (90 splits), which is the day the split was approved, recorded or paid out, depending on the company.
Not counted: Keurig Dr Pepper (8 to 1, report of August 7, 2018), T-Mobile US (1.5 to 1, report of August 8, 2013). The per-share figures were restated, but the restated periods carry another company’s net income (a reverse merger), so these are not splits.

How the list is made
- How splits are found: an annual or quarterly report re-files earlier periods with earnings per share divided by a split ratio and share counts multiplied by it, in at least three periods. Filings made before the split are not restated, so the split shows between two filings.
- When: the filings do not state in machine-readable form the day a split took effect, only bounds: the last share count on the cover of a report that is still on the old basis, and the first report on the new one (where the cover counts do not show the jump, the last report on the old basis). The split took effect in between.
- Date in the filing: some companies tag their split ratio (StockholdersEquity
NoteStockSplit ConversionRatio1) with a date. A date inside the window is shown, but companies use different days: when the board approved the split, the record date, or the day the new shares were paid out. - Coverage: XBRL filings start in 2009, so earlier splits are not here. A split shows only once reports on the new basis have re-filed enough periods, so the newest ones may follow with the next reports.
- Today’s members only: splits of companies that have since left the S&P 500 are not here.
