*This is the CUSIP number for the Issuer’s Class A ordinary shares, no par value per share (“Class A ordinary shares”). While the number of Class A ordinary shares reported in this Schedule 13G includes Class A ordinary shares issuable upon conversion, on a one-for-one basis, of the Issuer’s Class B ordinary shares, no par value (“Class B ordinary shares”) as well, the Class B ordinary shares are not registered under the Exchange Act and do not have a CUSIP.
 
(1)
Consists of (i) 36,710,809 Class A ordinary shares and (ii) an additional 36,710,809 Class A ordinary shares issuable upon conversion, on a one-for-one basis, of an equivalent number of Class B ordinary shares, held by the Reporting Person.
 
(2)
These 73,421,618 ordinary shares include 36,710,809 Class B ordinary shares that are entitled to five votes each (as well as 36,710,809 Class A ordinary shares entitled to one vote each), so the voting power possessed by the Reporting Person is proportionately greater (see footnote (4) below).
 
(3)
The percentage of class is based on 1,018,468,804 ordinary shares, consisting of 652,938,412 Class A ordinary shares and 365,530,392 Class B ordinary shares, issued and outstanding as of December 31, 2021, based on information provided by the Issuer to the Reporting Person.
 
(4)
This percentage constitutes the percentage of outstanding ordinary shares. Because the Class B ordinary shares are entitled to five votes, and Class A ordinary shares are entitled to one vote, per share, the percentage of the outstanding voting power possessed by the Reporting Person is 8.9%.

The following entities and individuals, listed in (i)-(v) below, who are filing this Statement of Beneficial Ownership on Schedule 13G (this “Statement”), are referred to herein collectively as the “Reporting Persons”, and the three individuals whose names appear in (iii)-(v) below, collectively, as the “Reporting Individuals”:

This Statement relates to the Class A ordinary shares, no par value per share, of the Issuer (“Class A ordinary shares”), which are registered under Section 12(b) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). While the Issuer’s Class B ordinary shares, no par value per share (“Class B ordinary shares”) are not registered under the Exchange Act, this Statement treats the Class B ordinary shares as part of one class together with the Class A ordinary shares, because Class B ordinary shares (i) generally possess the same rights as the Class A ordinary shares (except that Class B ordinary shares are entitled to five votes per share, whereas Class A ordinary shares are entitled to one vote per share) and (ii) generally automatically convert into Class A ordinary shares (on a one-for-one basis) upon transfer.
