The Company granted options to purchase 0.6 million and 0.6 million shares of the Company’s common stock during the six months ended March 29, 2025 and March 30, 2024, respectively, with weighted-average exercise prices of $78.07 and $72.27, respectively. There were 4.5 million options outstanding at March 29, 2025 with a weighted-average exercise price of $57.90.

The Company uses a binomial model to determine the fair value of its stock options. The weighted-average assumptions utilized to value these stock options are indicated in the following table:


	Three Months Ended						Six Months Ended
	March 29, 2025			March 30, 2024			March 29, 2025			March 30, 2024
Risk-free interest rate	4.2		%	4.4		%	4.2		%	4.4		%
Expected volatility	32.5		%	33.4		%	32.5		%	33.4		%
Expected life (in years)	4.8			4.8			4.8			4.8
Dividend yield	—			—			—			—
Weighted average fair value of options granted	$	22.06		$	26.27		$	26.30		$	25.04

The Company granted 0.7 million and 0.7 million restricted stock units (“RSUs”) during the six months ended March 29, 2025 and March 30, 2024, respectively, with weighted-average grant date fair values of $78.83 and $72.00 per unit, respectively. In addition, the Company granted 0.1 million and 0.1 million performance stock units (“PSUs”) during the six months ended March 29, 2025 and March 30, 2024, respectively, to members of its senior management team, which have a weighted-average grant date fair value of $79.00 and $71.92 per unit, respectively. Each recipient of PSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of a three-year performance period, provided that the Company’s defined Return on Invested Capital metrics are achieved. The Company also granted 0.1 million and 0.1 million of free cash flow performance stock units (“FCF PSUs”) based on a three-year cumulative free cash flow measure to members of its senior management team, which had a grant date fair value of $79.00 and $71.92 per unit during the six months ended March 29, 2025 and March 30, 2024, respectively. Each recipient of FCF PSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of the three-year measurement period. The PSUs and FCF PSUs cliff-vest three years from the date of grant, and the Company recognizes compensation expense ratably over the required service period based on its estimate of the probable number of shares that will vest upon achieving the measurement criteria. If there is a change in the estimate of the number of shares that are probable of vesting, the Company will cumulatively adjust compensation expense in the period that the change in estimate is made. The Company also granted 0.1 million and 0.1 million market stock units (“MSUs”) to members of its senior management team during the six months ended March 29, 2025 and March 30, 2024, respectively. Each recipient of MSUs is eligible to receive between zero and 200% of the target number of shares of the Company’s common stock at the end of a three-year performance period based upon achieving a certain total shareholder return relative to a defined peer group. The MSUs were valued at $87.41 and $88.06 per share using the Monte Carlo simulation model in fiscal 2025 and 2024, respectively. The MSUs cliff-vest three years from the date of grant, and the Company recognizes compensation expense for the MSUs ratably over the service period. At March 29, 2025, there was 1.8 million in aggregate unvested RSUs, PSUs, FCF PSUs and MSUs outstanding.

At March 29, 2025, there was $13.3 million and $68.1 million of unrecognized compensation expense related to stock options and stock units (comprised of RSUs, PSUs, FCF PSUs and MSUs), respectively, to be recognized over a weighted-average period of 2.5 and 2.1 years, respectively.
