The previous Form 4 for the Reporting Person, filed on August 17, 2026, inadvertently misstated the vesting schedule for the RSUs granted to the Reporting Person on August 14, 2026. That filing incorrectly stated that such RSUs will vest on August 14, 2027, subject to the Reporting Person's continued service through the vesting date. The RSUs will instead vest in equal annual installments over a three year period on each of the succeeding three anniversaries of the grant date, subject to the Reporting Person's continued service through each vesting date. This footnote corrects such disclosure.
