Split is new shares for old shares: in a 10-for-1 split one share becomes ten. Close before is the last close before the effective date and first close after is the first close on or after it, both as traded in DD's own history (not adjusted), so the two differ by about the split ratio plus that day's market move. Shares today shows how many shares one share held just before that split has become after it and every later split. Dates and ratios: EODHD. We leave out 3 price adjustments listed for DD that come from spin-offs or special distributions and are not stock splits.

How to read DD's split history
A stock split changes the number of shares and the price per share by the same factor, so the value of a holding stays the same on the day. DuPont de Nemours's 1-for-3 reverse split on 24 Jun 2026 is the latest in our data: every 3 shares held before became 1 share. Across all 2 splits since 2000, one share is still one share.
A split does not change what a company earns or what it is worth. Per-share figures such as earnings and dividends per share are restated by the ratio, which is why old prices look different in an adjusted chart than in the newspaper of the day. The DD stock page has the current score and fair value range, and the DD price history lists daily prices with both as-traded and adjusted closes.

Has DuPont de Nemours announced a new stock split?
Our data lists no split for DD after 24 Jun 2026 and no announced future one as of 22 Oct 2026. A company announces a split first, usually together with earnings or in a filing, and the split takes effect weeks later. The company's 8-K filings and press releases are the primary source.
What does a 1-for-3 reverse split mean for shareholders?
In a 1-for-3 reverse split the number of shares goes down and the price per share goes up by the same factor: every 3 shares held before became 1 share. The total value of a holding is not changed by the split itself; it only changes with the market price afterwards.
Does a stock split change what a company is worth?
No. A split cuts the same company into more (or fewer) pieces, so market value, earnings and dividends per share are all restated by the ratio. Charts and per-share figures in our data are adjusted for splits so that past and present prices can be compared.
Where does this split data come from?
Split dates and ratios come from EODHD. The closing prices around each split are the as-traded closes in our database. We leave out 3 other events listed for DD because they are price-adjustment factors for a spin-off or special distribution, not a stock split.
