(1) On August 18, 2026, the Reporting Person was granted an option to purchase 174,000 American Depository Shares ("ADSs"). This option grant is subject to forfeiture if shareholder approval of a proposed amendment to the Issuer's equity incentive plan to increase the number of shares reserved for issuance under the plan ("Shareholder Approval") is not obtained.

The remainder of the option grant will vest in equal, monthly installments beginning on the 18th day of the month subsequent to the month where Shareholder Approval was obtained until fully vested on the four-year anniversary of the Accrual Date, subject to the Reporting Person's continued service with the Issuer on each such vesting date.
(2) The pre-funded warrants became exercisable upon shareholder approval, which was obtained on March 2, 2026.
