As of December 31, 2021, we had authorized 100 million shares of preferred stock, with a par value of $0.00001 per share. There was no preferred stock outstanding as of December 31, 2021 and 2020. Potentially dilutive securities were not included in the computation of diluted earnings per share if to do so would have been anti-dilutive.
The SoftBank Specified Shares Amount of 48,751,557 shares of T-Mobile common stock was determined to be contingent consideration for the Merger and is not dilutive until the defined volume-weighted average price per share is reached.
