Net Loss per Share

Basic and diluted net loss per share attributable to common stockholders was calculated as follows:

	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands, except share and per share data)	2022		2021		2022		2021
Numerator:
Net loss attributable to common stockholders	$	(19,839)	$	(22,906)	$	(67,653)	$	(61,732)
Denominator:
Weighted‑average common shares outstanding, basic and diluted		36,905,818		34,436,793		35,766,217		34,360,274
Net loss per share attributable to common stockholders, basic and diluted	$	(0.54)	$	(0.67)	$	(1.89)	$	(1.80)

The Company’s potential dilutive securities 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 potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect:
