Earnings Per Share [Abstract] |
Loss Per Share | Loss Per Share Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding for the period. The Company’s unvested restricted common stock is not included in the determination of loss per share until the award vests. Since the Company had a net loss in each of the periods presented, basic and diluted net loss per common share are the same. In October 2025 and March 2026, the Company issued equity-classified Pre-Funded Warrants with a nominal exercise price of 0.0001 per share (see Note 10). In accordance with ASC 260, Earnings Per Share (ASC 260), shares issuable for little to no cash consideration should be included in the number of outstanding shares used to calculate basic loss per share as long as all conditions necessary for exercise are met. The Pre-Funded Warrants are therefore included as outstanding shares as of their issuance date to calculate the weighted average number of shares outstanding to calculate basic loss per share. The following outstanding potentially dilutive common stock equivalents were excluded from the computation of diluted net loss per share for the periods presented because including them would have been antidilutive (in thousands):
