The following table provides a reconciliation of the numerator and denominator used in computing basic and diluted net loss attributable to common stockholders per common share:


	Three Months Ended September 30,				Nine Months Ended September 30,
(in thousands, except per share amounts)	2022		2021		2022		2021
Numerator:
Net loss attributable to common stockholders	$	(33,286)	$	(50,294)	$	(180,703)	$	(167,183)
Denominator:
Weighted average common shares outstanding — basic and diluted	289,223,709		267,464,637		288,841,092		266,085,788

Dilutive common stock equivalents would include the dilutive effect of common stock options, convertible debt units, RSUs, and warrants for common stock equivalents. Potentially dilutive common stock equivalents were excluded from the diluted earnings per share denominator for all periods because of their anti-dilutive effect. Weighted average common shares outstanding includes outstanding pre-funded warrants with an exercise price of $0.01.

The table below presents potential shares of common stock that were excluded from the computation as they were anti-dilutive using the treasury stock method:


	As of September 30,
(in thousands)	2022	2021
Options to purchase common stock	19,236	14,798
Unvested restricted stock units	9,839	7,540
Total number of potentially issuable shares	29,075	22,338
