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


	For the Three Months Ended				For the Six Months Ended
	June 29, 2025		June 30, 2024		June 29, 2025		June 30, 2024
	(in thousands, except per share amounts)				(in thousands, except per share amounts)
Net income for basic and diluted net income per share	$	78,372	$	186,273	$	177,269	$	250,470
Weighted average common shares-basic		159,967		157,804		160,734		155,426
Effect of dilutive potential common shares:
Convertible note hedge warrant shares (1)		—		4,930		—		6,896
Restricted stock units		160		726		302		573
Stock options		2		9		3		12

Dilutive potential common shares		168		5,666		331		7,483
Weighted average common shares-diluted		160,135		163,470		161,065		162,909
Net income per common share-basic	$	0.49	$	1.18	$	1.10	$	1.61
Net income per common share-diluted	$	0.49	$	1.14	$	1.10	$	1.54

Convertible notes hedge warrant shares were calculated using the difference between the average Teradyne stock price for the period and the warrant price, multiplied by the number of warrant shares. The result of this calculation, representing the total intrinsic value of the warrant, was divided by the average Teradyne stock price for the period.

The computation of diluted net income per common share for the three and six months ended June 29, 2025, excludes the effect of the potential vesting of 1.4 million and 1.9 million, respectively, of restricted stock units because the effect would have been anti-dilutive.

The computation of diluted net income per common share for the three and six months ended June 30, 2024, excludes the effect of the potential vesting of 0.1 million and 0.5 million, respectively, of restricted stock units because the effect would have been anti-dilutive.
