Explanation of Responses:

1. On March 17, 2026, the Reporting Person filed a Form 4 that erroneously reported 371 time-based Restricted Stock Units ("RSUs") acquired under the Company's Long-Term Performance Incentive Plan. As reported in this amendment, the correct number of RSUs acquired was 724.

The RSUs will vest in three annual installments beginning on March 15, 2027.
