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. Basic net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, including the weighted average effect of prefunded warrants, and without consideration for potentially dilutive securities.

Diluted net loss per share is calculated by dividing net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding, including the weighted average effect of the prefunded warrants, plus dilutive securities. Shares of common stock issuable upon exercise, conversion or vesting of stock options, restricted stock units, warrants and the outstanding Series A convertible preferred stock are considered potential shares of common stock and are included in the calculation of diluted net loss per share using the treasury method when their effect is dilutive. Diluted net loss per share is the same as basic net loss per share for periods in which the effect of potentially dilutive shares of common stock is antidilutive.

The following table presents the number of shares subject to outstanding stock options, warrants, and Series A convertible preferred stock that were excluded from the computation of diluted net loss per share of common stock for the three months ended March 31, 2026 and 2025, as their effect was anti-dilutive:
