The following table sets forth the computation of basic and diluted net income (loss) per share:


	Three months ended October 31,				Nine months ended October 31,
(in thousands, except per share data)	2023		2022		2023		2022
Numerator (basic and diluted):
Net income (loss)	$	14,673	$	(1,641)	$	29,348	$	(25,934)
Denominator (basic):
Weighted-average common shares outstanding	85,697		84,572		85,424		84,349
Denominator (diluted):
Weighted-average common shares outstanding	85,697		84,572		85,424		84,349
Weighted-average dilutive effect of stock options and restricted stock units	1,425		—		1,283		—
Diluted weighted-average common shares outstanding	87,122		84,572		86,707		84,349
Net income (loss) per share:
Basic	$	0.17	$	(0.02)	$	0.34	$	(0.31)
Diluted	$	0.17	$	(0.02)	$	0.34	$	(0.31)

For the three months ended October 31, 2023 and 2022, approximately 0.6 million and 2.0 million shares, respectively, attributable to outstanding stock options and restricted stock units were excluded from the calculation of diluted net income (loss) per share as their inclusion would have been anti-dilutive.

For the nine months ended October 31, 2023 and 2022, approximately 1.0 million and 2.4 million shares, respectively, attributable to outstanding stock options and restricted stock units were excluded from the calculation of diluted net income (loss) per share as their inclusion would have been anti-dilutive.
