TNDM split history picture
Tandem Diabetes Care (TNDM) has 1 split in our TNDM split history database. The split for TNDM took place on October 10, 2017. This was a 1 for 10 reverse split, meaning for each 10 shares of TNDM owned pre-split, the shareholder now owned 1 share. For example, a 1000 share position pre-split, became a 100 share position following the split.

When a company such as Tandem Diabetes Care conducts a reverse share split, it is usually because shares have fallen to a lower per-share pricepoint than the company would like. This can be important because, for example, certain types of mutual funds might have a limit governing which stocks they may buy, based upon per-share price. The $5 and $10 pricepoints tend to be important in this regard. Stock exchanges also tend to look at per-share price, setting a lower limit for listing eligibility. So when a company does a reverse split, it is looking mathematically at the market capitalization before and after the reverse split takes place, and concluding that if the market capitilization remains stable, the reduced share count should result in a higher price per share.

Looking at the TNDM split history from start to finish, an original position size of 1000 shares would have turned into 100 today.
