16. Net Loss per Share

Basic and diluted net loss per share was calculated as follows:

	Years Ended December 31,
	2024			2023
	(in thousands, except shares and per share data)
Net loss	$	(7,732	)	$	(8,945	)
Preferred stock dividends		—			(77	)
Net loss attributable to common stockholders		(7,732	)		(9,022	)
Basic and diluted weighted average common shares outstanding		14,789,332			13,455,666
Basic and diluted net loss per share attributable to common stockholders	$	(0.52	)	$	(0.67	)

The Company’s potentially dilutive securities, which include stock options, unvested restricted common stock units and warrants, have been excluded from the computation of diluted net loss per share whenever the effect of including them would be to reduce the net loss per share. In periods where there is a net loss, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same.

The following potential common shares were excluded from the calculation of diluted net loss per share attributable to common stockholders for the years ended December 31, 2024 and 2023 because including them would have had an anti-dilutive effect:

	Years Ended December 31,
	2024		2023
Warrants to purchase common stock		898,622		1,113,622
Options to purchase common stock		4,385,477		3,977,289
Total		5,284,099		5,090,911
