All TMUS stock splits
| Effective date | Split | Close before | First close after | Shares today per 1 held before |
|---|---|---|---|---|
| 1 May 2013 | 1-for-2 | $11.84 | $16.52 | 0.5 |
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 TMUS'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.

How to read TMUS'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. T-Mobile US's 1-for-2 reverse split on 1 May 2013 is the latest in our data: every 2 shares held before became 1 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 TMUS stock page has the current score and fair value range, and the TMUS price history lists daily prices with both as-traded and adjusted closes.

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. Feed entries that are only price-adjustment factors for spin-offs or special distributions are not counted as splits.
