Form of Proxy for Annual General Meeting

to be held on Thursday, June 15, 2023 (Hong Kong time)

(or any adjourned meeting thereof)

Introduction

This Form of Proxy is furnished in connection with the solicitation by the board of directors of Baozun Inc., a Cayman Islands exempted company (the “Company”), of proxies from the holders of the issued and outstanding ordinary shares, par value US$0.0001 per share, of the Company (the “Ordinary Shares”) to be exercised at the annual general meeting of the Company (the “AGM”) to be held at Unit 1701-1707 & 1716, 17/F., BEA Tower Millennium City 5, 418 Kwun Tong Road, Kwun Tong, Hong Kong, on Thursday, June 15, 2023 at 2:00 p.m., Hong Kong time (or 2:00 a.m. on Thursday, June 15, 2023, New York time), and at any adjourned meeting thereof, for the purposes set forth in the accompanying notice of AGM.

Only the holders of record of the Ordinary Shares at the close of business on Tuesday, May 16, 2023, Hong Kong time, as the record date (the “Ordinary Shares Record Date”) are entitled to notice of and to vote at the AGM. In respect of the matters requiring shareholders’ vote at the AGM, each Class A ordinary share, par value US$0.0001 per share, is entitled to one vote, and each Class B ordinary share, par value US$0.0001 per share, is entitled to ten votes. The quorum of the AGM is one or more shareholders holding shares which represent, in aggregate, not less than one-tenth (1/10) of the votes attaching to all issued and outstanding Ordinary Shares and entitled to vote, present in person or by proxy or, if a corporation or other non-natural person, by its duly authorized representative.

The Ordinary Shares represented by all properly executed proxies returned to the Company will be voted at the AGM as indicated or, if no instruction is given, the holder of the proxy will vote the Ordinary Shares in his discretion, unless a reference to the holder of the proxy having such discretion has been deleted and initialed on this Form of Proxy. Where the chairman of the AGM acts as proxy and is entitled to exercise his discretion, he is likely to vote the Ordinary Shares for the resolutions. As to any other business that may properly come before the AGM, all properly executed proxies will be voted by the persons named therein in accordance with their discretion. The Company does not presently know of any other business which may come before the AGM. However, if any other matter properly comes before the AGM, or any adjourned meeting thereof, which may properly be acted upon, unless otherwise indicated the proxies solicited hereby will be voted on such matter in accordance with the discretion of the proxy holders named therein. Any person giving a proxy has the right to revoke it at any time before it is exercised (i) for holders of Ordinary Shares or American Depositary Shares (the “ADSs”), by submitting a written notice of revocation or a fresh Form of Proxy or a fresh Voting Card for ADSs, as the case may be, bearing a later date, which must be received by the deadlines for returning the Forms of Proxy or Voting Cards of ADSs set forth above, or (ii) for holders of Ordinary Shares only, by attending the AGM and voting in person at the AGM.

You may instruct your proxy to vote some or all of the Ordinary Shares in respect of which the proxy is appointed either for or against any resolution and/or abstain from voting as such proxy need not cast the votes in respect of your Ordinary Shares in the same way on any resolution. In this case, please specify in the voting boxes the number of Ordinary Shares in respect of which your proxy is to vote for or against or to abstain in respect of each resolution.

If two or more persons are jointly registered as holders of an Ordinary Share, the vote of the senior person who tenders a vote, whether in person or by proxy, shall be accepted to the exclusion of the votes of other joint holders. For this purpose, seniority shall be determined by the order in which the names stand on the Company’s register of shareholders in respect of the relevant Ordinary Shares. The senior holder should sign this Form of Proxy, but the names of all other joint holders should be stated on this Form of Proxy in the space provided.

To be valid, this Form of Proxy must be completed, signed and returned to Computershare Hong Kong Investor Services Limited at 17M Floor, Hopewell Centre, 183 Queen’s Road East, Wan Chai, Hong Kong as soon as possible no later than 2:00 p.m. June 13, 2023, Hong Kong time to ensure your representation at the AGM.
