F4 These restricted stock units vest in four equal annual installments beginning one year after the 05/08/2025 date of grant.
F5 On May 12, 2025 due to an administrative error, the Reporting Person filed a Form 4 which inadvertently omitted information from the transactional columns in Table II and overstated the amount of RSUs granted to the Reporting Person on May 8, 2025. The Form 4 has also been amended to clarify that grants of RSUs will be settled in common stock.

Remarks:

Shares issued for vesting of 1/18/2023 RSU grant and shares disposed in settlement of tax withholding obligations for such RSU vesting.
