Earnings Per Share

6 Months Ended

Jun. 30, 2023

Earnings Per Share Basic earnings per share (“EPS”) excludes dilution and is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding for the period. Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock using the treasury stock method. Potentially dilutive securities (consisting primarily of the 2025 Notes calculated using the if-converted method and warrants, stock options and RSUs calculated using the treasury stock method) are excluded from the diluted EPS computation in loss periods and when the applicable exercise price is greater than the market price on the period end date as their effect would be anti-dilutive.

The calculation of basic and diluted earnings per share was as follows (in thousands, except share and per share data):


	Three Months Ended June 30,				Six Months Ended June 30,
	2023		2022		2023		2022
Net loss attributable to common stockholders	$	(5,675)	$	(13,053)	$	(11,503)	$	(38,937)
Weighted-average common shares outstanding	111,080,287		107,511,660		109,847,937		106,585,684
Basic and diluted net loss per share	$	(0.05)	$	(0.12)	$	(0.10)	$	(0.37)

The following is a summary of outstanding anti-dilutive potential shares of common stock that have been excluded from diluted net loss per share attributable to common stockholders because their inclusion would have been anti-dilutive:
