The Company calculates basic loss per share by dividing net loss for each respective period by the weighted average number of common shares outstanding for each respective period. The Company computes diluted loss per share after giving consideration to the dilutive effect of stock options and unvested restricted stock that are outstanding during the period, except where such securities would be anti-dilutive. The Company’s diluted net loss per share is the same as basic net loss per share for the three months ended March 31, 2022 and 2021 given all potential shares of common stock are anti-dilutive as a result of the net loss for both periods.

The computations of basic and diluted net income (loss) per share attributable to common stockholders are as follows:

	Three Months Ended March 31,
	2022			2021
Net loss attributable to common stockholders (in thousands)	$	(28,168	)	$	(18,689	)
Weighted average shares outstanding basic and diluted		61,031,775			56,625,024
Net loss per share, basic and diluted	$	(0.46	)	$	(0.33	)

The following weighted-average common stock equivalents were excluded from the calculation of diluted loss per share because their inclusion would have been anti-dilutive:

	Three Months Ended March 31,
	2022		2021
Unvested Restricted Stock Units		1,183,013		—
Stock Options		1,416,330		7,667,963
Unsettled ESPP Contributions		3,870		2,293
Total common stock equivalents excluded from diluted net loss per share		2,603,213		7,670,256
