The following table summarizes the computations of basic and diluted net income per share for the three and nine months ended December 31, 2025 and 2024 (in thousands, except per share amounts):


	Three Months Ended December 31,				Nine Months Ended December 31,
	2025		2024		2025		2024
Net income	$	251,039	$	200,147	$	567,724	$	487,463

Shares used in net income per share computation:
Weighted average shares outstanding - basic	146,827		150,647		147,265		152,127
Effect of potentially dilutive equivalent shares	1,623		1,248		1,370		1,379
Weighted average shares outstanding - diluted	148,450		151,895		148,635		153,506

Net income per share:
Basic	$	1.71	$	1.33	$	3.86	$	3.20
Diluted	$	1.69	$	1.32	$	3.82	$	3.18

Share equivalents attributable to outstanding stock options, restricted stock units and employee share purchase plans totaling 0.6 million and 0.9 million for the nine months ended December 31, 2025 and 2024, respectively, were excluded from the calculation of diluted net income per share because their effect would have been antidilutive. Antidilutive share equivalents totaled 0.8 million for the three months ended December 31, 2024 and were not material for the three months ended December 31, 2025. A small number of performance-based restricted stock units were not included in the diluted net income per share calculation because all necessary conditions had not been satisfied by the end of the respective period, and those shares were not issuable if the end of the reporting period were the end of the performance contingency period.
