Earnings Per Share [Abstract] |
Net Loss Per Share | 12. Net Loss Pe r Share Basic and diluted net loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding. The weighted-average common shares outstanding used in the basic and diluted net loss per share calculation includes the pre-funded warrants issued in connection with the Company’s follow-on public offering in June 2023 of 204,081 and registered direct offering in February 2023 of 1,229,224, as the pre-funded warrants are exercisable for nominal cash consideration. In September 2023, 1,229,224 of the pre-funded warrants were exercised in a cashless transaction which resulted in 1,229,221 shares of common stock being issued to the investor. As of March 31, 2024, 204,081 pre-funded warrants were outstanding. The Company has generated a net loss in all periods presented, so the basic and diluted net loss per share are the same, as the inclusion of the potentially dilutive securities would be anti-dilutive. The C ompany excluded the following from the computation of diluted net loss per share attributable to common stockholders because including them would have had an anti-dilutive effect:
