Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period, including 9.6 million shares of pre-funded warrants to purchase shares of common stock. Diluted net loss per share is the same as basic net loss per share for the periods presented since the effects of potentially dilutive securities are antidilutive given the net loss of the Company.

Basic and diluted net loss per share is calculated as follows (in thousands, except share and per share amounts):


	Three Months Ended June 30,						Six Months Ended June 30,
	2026			2025			2026			2025
Net loss	$	(4,781	)	$	(5,094	)	$	(9,871	)	$	(10,644	)
Net loss per share—basic and diluted	$	(0.25	)	$	(1.24	)	$	(0.51	)	$	(3.65	)
Weighted-average number of shares used in computing net loss per share—basic and diluted		19,467,091			4,119,153			19,468,087			2,920,157

The following outstanding potentially dilutive securities have been excluded from the calculation of diluted net loss per share, as their effect is antidilutive:
