(a) Compensatory Arrangements of Certain Officers

Approval of revised forms of Equity Agreements. On February 12, 2026, the Talent and Compensation Committee (the “Committee”) of our Board granted equity to executive officers pursuant to revised forms of Non-Qualified Stock Option Agreements (the “Stock Option Agreement”), Restricted Stock Unit Agreements (the “RSU Agreement”) and Performance Stock Unit Agreements (the “PSU Agreement”) for fiscal 2026 (the Stock Option Agreement, the RSU Agreement, and the PSU Agreement, collectively the “Equity Agreements”). The Equity Agreements reflect a clarification to the definition of “for Cause” termination, expand eligibility for prorated vesting on retirement if certain age and service requirements are met, augment the language relating to compensation recoupment, extend the option exercise period for certain terminations “without Cause”, and make additional clarifying language changes, as set forth in the agreements.

The above description of the Stock Option Agreement, the RSU Agreement, and the PSU Agreement do not purport to be complete and are qualified in their entirety by reference to the agreements attached to this report as Exhibit 10.23, 10.24, and 10.25, respectively, and incorporated herein by reference.
