Holders of American Depositary Shares of the Company (the “ADSs”) issued by The Bank of New York Mellon as the depositary of the ADSs (the “Depositary”), as of the close of business on Wednesday, May 17, 2023, New York time (the “ADSs Record Date”, and together with the Ordinary Shares Record Date collectively known as the “Record Date”), will be able to instruct the Depositary, being the holder of record of the Class A ordinary shares represented by the ADSs, as to how to vote the Class A ordinary shares represented by such ADSs. The Depositary will endeavor, to the extent practicable and legally permissible, to vote or cause to be voted at the forthcoming AGM the Class A ordinary shares represented by the ADSs in accordance with the instructions that it has properly received directly from the ADS holders if the ADSs are held by holders on the books and records of the Depositary or indirectly through a bank, brokerage or other securities intermediary if the ADSs are held by any of them on behalf of holders. Please be aware that, because of the time difference between Hong Kong and New York, any ADS holders that cancel their ADSs in exchange for Class A ordinary shares of the Company on Wednesday, May 17, 2023, New York time will no longer be ADS holders with respect to such canceled ADSs as of the ADSs Record Date and will not be able to instruct the Depositary as to how to vote the Class A ordinary shares represented by such canceled ADSs as described above; such ADS holders will also not be holders of the Class A ordinary shares represented by such canceled ADSs as of the Ordinary Shares Record Date for the purpose of determining the eligibility to attend and vote at the forthcoming AGM.
