F2 · kind: This transaction includes the sale of issuer common shares to cover the reporting person's tax withholding obligation for vesting dates on August 25, November 13, and November 14, 2025. As a result of an administrative error by the issuer's third-party service provider, cash was paid on behalf of the reporting person for tax withholding obligations on the vesting date, August 25, 2025. A corresponding sale of issuer common shares to cover the reporting person's tax withholding obligation on August 25, 2025 could not be completed until the opening of the issuer's next window period. Accordingly, the portion of the above shares attributed to the vesting on August 25, 2025 were sold November 17, 2025, the first available date during an open window period on which the shares could be sold on behalf of the reporting person.
