Rule 10b5-1 Trading Plans

During thequarter ended September 28, 2026, our directors and/or officers (as defined in Rule 16a-1(f) under the Exchange Act) adopted or terminated the contracts, instructions, or written plans for the purchase or sale of our securities set forth in the table below.

(1)

Contract, instruction, or written plan intended to satisfy the affirmative defense conditions of Rule 10b5-1(c) under the Exchange Act.

(2)

“Non-Rule 10b5-1 trading arrangement” as defined in Item 408(c) of Regulation S-K under the Exchange Act.

(3)

Rule 10b5-1 trading arrangement that was intended to provide for “eligible sell-to-cover transactions” (as described in Rule 10b5-1(c)(1)(ii)(D)(3) under the Exchange Act) to satisfy tax withholding obligations arising exclusively from vesting of RSUs or PRUs. The number of shares subject to covered RSUs or PRUs that were to be sold to satisfy applicable tax withholding obligations upon vesting were not currently determinable as the number would vary based on the market price of our common stock and the extent to which vesting conditions are satisfied. This sell-to-cover arrangement provided solely for the automatic sale of shares that would otherwise be issuable in respect of a covered RSU or PRU in an amount sufficient to satisfy the applicable withholding obligation, with the proceeds of the sale delivered to the Company in satisfaction of the applicable withholding obligation.

(4)

The duration of the trading arrangement was perpetual; provided, that the trading arrangement would expire if the officer terminated the trading arrangement in compliance with Rule 10b5-1 and Company policy, or upon certain other events outside of the officer’s control including, but not limited to, extraordinary corporate transactions or bankruptcy.
