Remarks:

The Reporting Person's Form 4 filed on September 8, 2025 originally reported an RSU award that vests over four years, with 25% of the total number of shares underlying the award vesting on September 10, 2026 and 1/16 of the total number of such shares vesting quarterly thereafter on each subsequent December 10, March 10, June 10 and September 10. The vesting of the original award was subsequently adjusted to vest over three years, such that 1/6 of the total number of shares underlying the award vested on December 10, 2025 and 1/12 of the total number of such shares vest quarterly thereafter on each subsequent March 10, June 10, September 10 and December 10, subject to the Reporting Person continuing as a service provider through each such vesting date.
