Earnings Per Share [Abstract] |
Net Loss Per Share | 10. Net Loss Per Share The Company calculates basic and diluted net loss per share attributable to common stockholders in conformity with the two-class method required for participating securities. For the three months ended March 31, 2023 and 2022, the Company had voting and non-voting common stock outstanding. Since the rights of the voting and non-voting common stock are identical, except with respect to voting, the undistributed losses of the Company have been allocated on a proportionate basis to the two classes. Basic net loss per share of common stock is computed by dividing the net loss per share of common stock by the weighted average number of shares of common stock outstanding for the period. The weighted-average shares of common stock outstanding as of March 31, 2023 included outstanding pre-funded warrants to purchase up to an aggregate of 4,130,442 shares of common stock. Diluted net loss per share is calculated using the if-converted method, which assumes conversion of all non-voting common stock to voting common stock.
