•such other business as may properly be brought before the Annual Meeting or any adjournment or postponement thereof.

The Company’s Board of Directors recommends a vote FOR the election of the 11 director nominees, FOR the ratification of the appointment of Ernst & Young LLP as our independent auditors, FOR the approval, on an advisory basis, of compensation paid to our named executive officers for the fiscal year ended December 25, 2025, and FOR the approval of the Amended & Restated 2017 Stock Incentive Plan.
