Basic loss per share is computed by dividing net loss by the weighted-average shares of common stock outstanding, without consideration to common stock equivalents:

	Three Months Ended March 31,

Numerator:
Net loss	$	(6,662	)	$	(10,282	)
Denominator:
Weighted-average common stock outstanding		32,961,180			31,933,794
Net loss per share — basic and diluted	$	(0.20	)	$	(0.32	)

The Company’s potentially dilutive shares, which include any outstanding stock options, warrants and unvested restricted stock, are considered to be common stock equivalents and are only included in the calculation of diluted net loss when their effect is dilutive.

The Company excluded the following potential common stock equivalents from the computation of diluted net loss per share attributable to common stockholders because including them would have had an anti-dilutive effect for the three months ended March 31, 2022 and 2021.
