Explanation of responses
- F1These shares represent a restricted stock unit award granted to the reporting person. One-third (1/3) of the restricted stock units will vest on August 28, 2027, and the remaining two-thirds (2/3) of the restricted stock units will vest in eight equal quarterly installments beginning on November 28, 2027.
- F2Represents shares issued upon payout of the Performance Stock Units granted in August 2023.

Deferred Compensation Plan; the deferred Performance Stock Units are reported in Table II. The remaining 2,449 underlying shares of common stock were settled, of which 758 shares were withheld for taxes and 1,691 shares were delivered to the reporting person.
- F3These shares were withheld by the company to discharge withholding tax obligations of the reporting person and do not constitute an actual sale or other open market transaction.

Of the 2,392 deferred stock units, 57 units were withheld to satisfy FICA tax obligations, resulting in 2,335 deferred stock units credited to the reporting person's Plan account. The deferred stock units are deemed invested in our common stock and are payable solely in shares of common stock upon a qualifying distribution event under the Plan.
