Biogen Inc (BIIB) Stock Split History

Biogen Inc has split its stock 2 times since its initial public offering (IPO). The first stock split occurred on December 21, 1999 with the ratio of 2-for-1, meaning that for 1 share of BIIB owned pre-split, shareholders then owned 2 shares. The most recent stock split took place on January 18, 2001 on a 3-for-1 basis.

These actions have increased BIIB stock's liquidity and made it more appealing to a larger group of investors. However, it's important to remember that a stock split only change the number of shares and the price per share with no impact on Biogen Inc's total market capitalization.

The answer will depend on the decisions of the company's managers and market volatility. Biogen Inc has not made an official announcement regarding whether it will enact a stock split or reverse stock split, but it has a history of doing so when BIIB stock prices become too high or too low for retail investors. Therefore, the ultimate decisions will certainly be made by Biogen Inc's board of directors. Typically, no action is taken until its price per share reaches a specific threshold.
