Reverse ADS split description | Effective on March 7, 2022, the Group changed the ratio of the American depositary shares (“ADSs”) representing its Class A ordinary shares from one (1) ADS representing thirty (30) Class A ordinary share to one (1) ADS representing one hundred and fifty (150) Class A ordinary shares. For the ADS holders, the change in the ADS ratio will have the same effect as a one-for-five reverse ADS split. There will be no change to the Group’s Class A ordinary shares. The exchange of every five (5) then-held (old) ADSs for one (1) new ADS will occur automatically with the then-held ADSs being cancelled and new ADSs being issued by the depositary bank, in each case as of the effective date for the ADS ratio change. No fractional new ADSs will be issued in connection with the change in the ADS ratio. | Effective on March 7, 2022, the Group changed the ratio of the American depositary shares (“ADSs”) representing its Class A ordinary shares from one (1) ADS representing thirty (30) Class A ordinary share to one (1) ADS representing one hundred and fifty (150) Class A ordinary shares.
