Explanation of Responses:

1. On May 29, 2024, the Reporting Person was granted PRSUs. Each PRSU represents a contingent right to receive a share of the Issuer's Common Stock upon settlement. The Compensation Committee of the Issuer's Board of Directors certifies attainment based on the Issuer's satisfaction of certain performance criteria. The performance criteria were met and 220,667 PRSUs were certified as attained on February 27, 2026. 100% of the PRSUs shall vest and become shares of the Issuer's Common Stock on April 6, 2026, subject to the Reporting Person's continued service through the vesting date. Due to an administrative error, the Form 4 filed on March 3, 2026 included an incorrect figure for the number of PRSUs certified. As reported in this amendment, the number of PRSUs certified was 220,667. There are no other changes reported in this amendment.

2. Shares held following the reported transaction include 819,027 restricted stock units, which are subject to forfeiture until they vest.
