GRANT OF RESTRICTED SHARE UNIT AWARDS

Grant of Restricted Share Unit Awards

Baozun Inc. (the “Company”, together with its consolidated subsidiaries and its affiliated consolidated entities, the “Group”) hereby announces that on April 1, 2023 (Hong Kong time), the Company granted or proposed to grant restricted share unit awards (the “RSUs”) under the 2022 share incentive plan of the Company (the “2022 Plan”) to certain grantees (the “Grantees”), the details of which are set forth as follows:

The RSUs are subject to the terms and conditions of the 2022 Plan and award agreements applicable to the Grantees. Details of the 2022 Plan are set out in Appendix IV – The 2022 Plan of the circular of the Company dated October 5, 2022.

As of the date of this announcement, taking into account the proposed grant of 1,752,984 RSUs to Mr. Qiu which is subject to the approval by shareholders (the “Shareholders”) of the Company at the general meeting of the Company, 8,250,161 Shares remained available for future grants under the 2022 Plan.

Proposed Grant of RSUs to a Director

Among the 5,330,463 RSUs, 1,752,984 RSUs were proposed to grant to Mr. Qiu, who is the chief executive officer of the Company and a Director, which has been reviewed and approved by the independent Directors.

The proposed grant of 1,752,984 RSUs (representing 1,752,984 Shares), being the only grant of awards to Mr. Qiu during the 12-month period up to the Grant Date, represents in aggregate over 0.1% of the shares of the Company in issue as at the Grant Date. Thus, in accordance to the terms and conditions of the 2022 Plan and Rules 17.04(2) and 17.04(4) of the Listing Rules, the proposed grant of 1,752,984 RSUs to Mr. Qiu is subject to the approval of the Shareholders in general meeting where Mr. Qiu and his associates (as defined in the Listing Rules) and all core connected persons (as defined in the Listing Rules) of the Company shall abstain from voting in favour for such proposed grant. Subject to the Shareholders’ approval of the proposed grant of RSUs to Mr. Qiu, the number of Shares issued and to be issued in respect of all awards and options granted to Mr. Qiu under all share incentive schemes of the Company in the 12-month period up to and including the Grant Date would be 1,752,984 Shares, representing approximately 0.99% of the total issued shares of the Company as at the date of this announcement and approximately 0.98% of the total issued shares of the Company as enlarged by such issue of 1,752,984 Shares.

The compensation committee (the “Compensation Committee”) of the Company and all independent Directors have reviewed and fully considered the grant of RSUs to Mr. Qiu, and is of view that, (i) Mr. Qiu, as a Director and the chief executive officer of the Company, has made significant contributions to the Company in managing the overall operations and improving the performance of the Company; (ii) the vesting arrangement for the RSUs granted to Mr. Qiu is performance-based and serves as the Board’s appreciation and recognition of Mr. Qiu’s contribution towards the growth of the Group; and (iii) the RSUs granted to Mr. Qiu will provide sufficient incentive to retain Mr. Qiu and motivate him to create more value in the Group’s long- term development. Therefore, the Compensation Committee and all independent Directors are of view that the proposed grant of RSUs to Mr. Qiu and the vesting arrangement will closely align the purpose of the 2022 Plan and the interests and benefits of the Group, the Board and the management of the Group, and thus is appropriate and reasonable and in the interests of the Company and its Shareholders as a whole.

Mr. Qiu is one of the beneficiaries of the weighted voting rights of the Company. Pursuant to the note to Rule 17.04(1) of the Listing Rules, the nominating and corporate governance committee of the Company have reviewed and fully considered the proposed grant of RSUs to Mr. Qiu, including the reasons of such grant, and is of the view that, the grant of RSUs to Mr. Qiu are fair and reasonable and in the interest of the Company and its Shareholders as a whole.

General

An ordinary resolution will be proposed at the forthcoming annual general meeting of the Company (the “AGM”) to be convened and held in 2023 for the Shareholders to consider and, if thought fit, approve the proposed grant of 1,752,984 RSUs to Mr. Qiu.

A circular containing, among other things, (i) further information on the proposed grant of RSUs to Mr. Qiu; and (ii) a notice convening the AGM, are expected to be despatched to the Shareholders in due course.
