Loss Per Common Share

6 Months Ended

Jun. 30, 2025

Basic and diluted loss per common share is computed by dividing net loss attributable to common stockholders by the weighted average number of common shares outstanding during the period. Diluted net loss per common share is the same as basic net loss per common share for the three and six months ended June 30, 2025 and 2024, because the effect of adjusting the weighted average number of common shares outstanding during the period for the potential dilutive effect of common stock equivalents would be antidilutive due to the Company’s net loss position for these periods. The 1,961,754 shares of common stock underlying the outstanding March 2025 Pre-Funded Warrants have been included in the weighted-average number of shares of common stock used to calculate net loss per share, basic and diluted, attributable to common stockholders because the shares may be issued for little or no consideration, they are fully vested, and the March 2025 Pre-Funded Warrants are immediately exercisable upon their issuance date.

The following common stock equivalents were excluded from the calculation of diluted net loss per share applicable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:


	As of June 30,
	2025	2024
Anti-dilutive common stock equivalents:
October 2024 Common Warrants	2,398,414	—
March 2025 Common Warrants	8,316,882	—
Stock options outstanding	2,426,530	1,226,714
Unvested RSAs	—	40,137
Unvested RSUs	283,500	—
Total anti-dilutive common stock equivalents	13,425,326	1,266,851
