F2: ADSs acquired upon vesting of Restricted Share Units ("RSUs").

F3: Each RSU represents a contingent right to receive one ADS.

F5: These ADSs were sold automatically to cover taxes upon vesting of RSUs.

F6: The RSUs vest in equal annual installments over four years beginning on 06/29/2024, the first anniversary of the date of grant, subject to continuous service. Vested shares will be delivered in the form of ADSs to the reporting person following vesting.
