Earnings Per Share

The following table sets forth the computation of basic and diluted income from continuing operations per common share:


	Year Ended September 30,
(In thousands, except per share data)	2021		2020		2019
Numerator:
Net income (loss) attributable to Evoqua Water Technologies Corp.	$	51,482	$	113,649	$	(9,523)
Denominator:
Denominator for basic net income per common share—weighted average shares	119,575		116,721		114,703
Effect of dilutive securities:
Share‑based compensation	3,368		4,342		—
Denominator for diluted net loss per common share—adjusted weighted average shares	122,943		121,063		114,703
Basic income (loss) per common share	$	0.43	$	0.97	$	(0.08)
Diluted income (loss) per common share	$	0.42	$	0.94	$	(0.08)

Since the Company was in a net loss position for the year ended September 30, 2019, there was no difference between the number of shares used to calculate basic and diluted loss per share. Because of their anti-dilutive effect, 1,784 and 2,512 common share equivalents, comprised of employee stock options, have been excluded from the diluted EPS calculation for the years ended September 30, 2021 and 2020, respectively.
