The following table summarizes the computations of basic and diluted net income per share for the three and six months ended September 30, 2026 and 2025 (in thousands, except per share amounts):


	Three Months Ended September 30,				Six Months Ended September 30,
	2026		2025		2026		2025
Net income	$	180,035	$	170,670	$	415,732	$	316,685

Shares used in net income per share computation:
Weighted average shares outstanding - basic	142,946		147,123		143,214		147,487
Effect of potentially dilutive equivalent shares	824		1,299		1,184		1,244
Weighted average shares outstanding - diluted	143,770		148,422		144,398		148,731

Net income per share:
Basic	$	1.26	$	1.16	$	2.90	$	2.15
Diluted	$	1.25	$	1.15	$	2.88	$	2.13

Share equivalents attributable to outstanding restricted stock units and employee share purchase plans totaling 0.8 million and 0.2 million for the three months ended September 30, 2026 and 2025, respectively, and 0.8 million and 0.9 million for the six months ended September 30, 2026 and 2025, respectively, were excluded from the calculation of diluted net income per share because their effect would have been antidilutive. 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.
