15. LOSS PER SHARE

Basic and diluted loss per share is computed by dividing net loss attributable to common stockholders by the weighted-average common shares outstanding (in thousands, except share and per share data):


	FOR THE YEAR ENDED DECEMBER 31,
	2021			2020
Numerator:
Net loss	$	(58,160	)	$	(39,341	)
Net loss attributable to common stockholders—basic and diluted		(58,160	)		(39,341	)
Denominator:
Weighted-average common stock outstanding—basic and diluted		39,202,086			8,144,855
Net loss per share attributable to common stockholders—basic and diluted	$	(1.48	)	$	(4.83	)

The Company’s potentially dilutive securities, which include preferred stock, restricted stock, stock options, and warrants, have been excluded from the computation of diluted net loss per share as the effect would be to reduce the net loss per share. Therefore, 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 Company excluded the following from the computation of diluted net loss per share attributable to common stockholders at December 31, 2021 and 2020 because including them would have had an anti-dilutive effect:
