On May 13, 2026, the Compensation Committee of the Issuer's Board of Directors determined that the performance objective goals of the PSUs for the period ending March 27, 2026 had been met for the aggregate number of shares shown. Following certification, the certified portion of the award remains subject to the time-based vesting conditions, with the full amount scheduled to vest on May 16, 2026.
