(F1)Includes restricted stock units. On October 20, 2026, the Compensation, Culture and People Committee of the Board of Directors of the Issuer approved a modification to the vesting schedule applicable to 4,005 of the restricted stock units previously granted to the Reporting Person on May 26, 2026. The restricted stock units were originally scheduled to vest in three equal installments over a three-year period, but will instead vest on a quarterly basis over a three-year period. Approximately 16.67% of the restricted stock units vested on November 6, 2026 (to account for the quarterly installment that would otherwise have vested during the first fiscal quarter of fiscal year 2027) and the remaining approximately 83.33% will vest in ten equal quarterly installments beginning on January 13, 2027, subject to the Reporting Person's continued service through each applicable vesting date.
