The Plan is administered by an authorized administrator appointed by the Board of Directors of the Company set forth in the Plan (the “Plan Administrator”). The maximum number of shares which may be issued pursuant to all awards under the Plan will increase on January 1 of each of 2019, 2020, 2021 and 2022 by 5% of the total number of ordinary shares of all classes of the Company outstanding on that day immediately before such annual increase pursuant to the Plan. With effect on January 1, 2019, July 25, 2019, January 1, 2020, January 1, 2021 and January 1, 2022, the maximum number of shares which may be issued pursuant to all awards under the Plan increased to 100,129,938, 103,129,938, 123,292,170, 148,888,743 and 176,775,641 Class A ordinary shares.

(a) Option granted to Eligible Persons The following table summarizes the Company’s share option activity under the Plan: Number of Weighted Weighted Aggregate $ Years $ Outstanding, January 1, 2019 35,706,882 12.54 Granted 15,327,884 15.00 Exercised (3,736,976 ) 5.58 Forfeited (109,236 ) 14.24 Outstanding, December 31, 2019 47,188,554 13.89 8.18 1,242,496 Vested and expected to vest at December 31, 2019 47,188,554 13.89 Exercisable as of December 31, 2019 19,664,736 12.35 7.35 548,035 Outstanding, January 1, 2020 47,188,554 13.89 Granted 5,809,024 18.59 Exercised (5,486,180 ) 11.29 Forfeited (45,678 ) 14.09 Outstanding, December 31, 2020 47,465,720 14.76 7.57 8,747,373 Vested and expected to vest at December 31, 2020 47,465,720 14.76 Exercisable as of December 31, 2020 25,298,368 13.73 7.03 4,688,260 Outstanding, January 1, 2021 47,465,720 14.76 Granted 4,162,121 269.09 Exercised (5,405,228 ) 14.44 Forfeited – Outstanding, December 31, 2021 46,222,613 37.70 6.89 8,822,987 Vested and expected to vest at December 31, 2021 46,222,613 37.70 Exercisable as of December 31, 2021 30,707,210 14.13 6.32 6,435,641 The aggregate intrinsic value is calculated to be the difference between the exercise price of the underlying awards and the fair value of the underlying stock at each reporting date, for those awards that have an exercise price below the estimated fair value of the Company’s ordinary shares. The Company calculated the estimated fair value of the options on the respective grant dates using the Black-Scholes option pricing model with the following assumptions. Granted in 2019 Granted in 2020 Granted in 2021 Risk-free interest rates 2.34% – 2.68% 0.39% – 1.66% 0.74% – 1.07% Expected term 5.5 – 8.5 years 5.5 – 7.5 years 5.6 – 7.5 years Expected volatility 33.0% – 35.0% 32.4% – 33.7% 32.1% – 33.0% Expected dividend yield – – – Fair value of share options $4.58 – $13.59 $13.81 – $50.58 $71.70 – $84.14 The Black-Scholes option pricing model was applied in determining the estimated fair value of the share options granted to Eligible Persons. The model requires the input of highly subjective assumptions including the estimated expected stock price volatility and the expected term of the option for which employees are likely to exercise their share options. The risk-free rate for periods within the contractual life of the option is based on the US Treasury Yields at the time of grant. The Company has used the simplified method to determine the expected term due to insufficient historical exercise data to provide a reasonable basis to estimate expected term. The Company’s management is ultimately responsible for the determination of the estimated fair value of its ordinary shares. The weighted-average grant-date fair value of share options granted during the years of December 31, 2019, 2020 and 2021 were $12.05, $37.86 and $75.83, respectively. The total fair value of share options vested during the years ended December 31, 2019, 2020 and 2021 was $44,688, $88,114 and $88,507, respectively. The aggregate intrinsic value of options exercised during the years ended December 31, 2019, 2020 and 2021 was $64,097, $767,203 and $1,361,800 respectively. As of December 31, 2021, there were $585,256 total unrecognized share-based compensation cost related to unvested options which is expected to be recognized over a weighted-average period of 3.68 years. Total unrecognized compensation cost may be adjusted for future changes in actual forfeitures. (b) RSAs/RSUs granted to Eligible Persons The following table summarizes the Company’s RSAs/RSUs activity under the Plan: Number of Weighted Weighted Aggregate $ Years $ Unvested, January 1, 2019 4,754,972 12.34 9.17 53,826 Granted 6,249,313 20.50 Vested (2,131,415 ) 13.67 Forfeited (791,433 ) 15.22 Unvested, December 31, 2019 2020 8,081,437 18.02 8.93 325,035 Granted 5,034,735 72.37 Vested (3,332,063 ) 19.25 Forfeited (442,181 ) 28.74 Unvested, December 31, 2020 2021 9,341,928 46.36 8.64 1,859,511 Granted 3,551,491 258.97 Vested (4,127,006 ) 40.59 Forfeited (637,193 ) 102.92 Unvested, December 31, 2021 8,129,220 137.76 8.47 1,818,588 Share-based compensation cost for RSAs and RSUs is measured based on the fair value of the Company’s ordinary shares on the date of grant.
