Id	Content
F1	Each performance share unit represents a contingent right to receive one class A ordinary share. The performance share units will vest on March 31, 2028, subject to continued employment conditions and accelerated vesting in certain circumstances, based upon the highest trading day average closing price of the class A ordinary shares of the Company for any 90 consecutive trading days (the "Average Share Price") during the performance period from July 26, 2023 to March 31, 2028: (i) entry (50%) if the Average Share Price is greater than $475, (ii) target (100%) if the Average Share Price is $500 and (iii) stretch (200%) if the Average Share Price is $550.
F2	No performance share units will vest if the average closing price of the Company's shares for the 90 consecutive trading days ending on March 31, 2028 is below $475. If the Average Share Price is between the entry, target and stretch levels, a proportionate number of PSUs between those levels will be earned.
