EARNINGS PER SHARE

6 Months Ended

Jun. 30, 2021

The following table sets forth the computation of basic and diluted earnings per share of our common stock, net of non-controlling interest and dividends on preferred stock:


	Three months ended June 30,				Six months ended June 30,
(in thousands, except per share amounts)	2021		2020		2021		2020
Income (loss) from continuing operations attributable to stockholders of common stock	$	1,395	$	(17,991)	$	(14,069)	$	(51,430)
Income (loss) from discontinued operations attributable to stockholders of common stock, net of tax	—		(113)		—		1,800
Net income (loss) attributable to stockholders of common stock	$	1,395	$	(18,104)	$	(14,069)	$	(49,630)

Weighted average shares used to calculate basic earnings (loss) per share	85,724		46,853		78,589		46,628
Dilutive effect of stock options, restricted stock and performance units	1,279		—		—		—
Weighted average shares used to calculate diluted earnings (loss) per share	87,003		46,853		78,589		46,628

Basic earnings (loss) per share
Continuing operations	$	0.02	$	(0.39)	$	(0.18)	$	(1.10)
Discontinued operations	—		—		—		0.04
Basic earnings (loss) per share	$	0.02	$	(0.39)	$	(0.18)	$	(1.06)

Diluted earnings (loss) per share
Continuing operations	$	0.02	$	(0.39)	$	(0.18)	$	(1.10)
Discontinued operations	—		—		—		0.04
Diluted earnings (loss) per share	$	0.02	$	(0.39)	$	(0.18)	$	(1.06)

Because we incurred a net loss in the six months ended June 30, 2021 and in the three and six months ended June 30, 2020, basic and diluted shares are the same.

If we had net income in the six months ended June 30, 2021, diluted shares would include an additional 1.4 million shares. If we had net income in the three and six months ended June 30, 2020, diluted shares would include an additional 33.3 thousand and 216.1 thousand shares, respectively.

We excluded 0.3 million and 1.5 million shares related to stock options from the diluted share calculation for the three months ended June 30, 2021 and 2020, respectively, because their effect would have been anti-dilutive. We excluded 0.4 million and 1.7 million shares related to stock options from the diluted share calculation for the six months ended June 30, 2021 and 2020, respectively, because their effect would have been anti-dilutive.
