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 August 28, 2026 (Hong Kong time), the Company granted and 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.

Pursuant to Rule 17.04(1) of the Listing Rules, the grant of RSUs to the above Directors has been approved by the Board (including the independent Directors), save that each Director has abstained from voting on the relevant resolutions in relation to the grant of RSUs to himself/herself. Each of the grant of RSUs to the Directors forms part of his/her remuneration package under his/her service contract with the Company.

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 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 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 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.

To the best of the Directors’ knowledge, information and belief, having made all reasonable enquiry, save as disclosed in this announcement in relation to the grants to Mr. Qiu and Ms. Bin Yu, none of the Grantees is (i) a Director, a chief executive, a senior manager, or a substantial shareholder of the Company, or an associate of any of them; or (ii) a participant with options and awards granted and to be granted exceeding the 1% individual limit under Rule 17.03D of the Listing Rules; or (iii) a related entity participant or service provider with options and awards granted and to be granted in any 12-month period exceeding 0.1% of the total issued Shares (excluding treasury shares). None of the grant will be subject to approval by the Shareholders.

As of the date of this announcement, 16,586,516 Shares remained available for future grants under the 2022 Plan in accordance with the terms of the 2022 Plan, of which 5,231,555 Shares are available for future grants to the service providers.

Hong Kong, August 28, 2026

As at the date of this announcement, our board of directors comprises Mr. Vincent Wenbin Qiu as the chairman, Mr. Junhua Wu, Dr. Jun Wang and Ms. Bin Yu as directors, and Mr. Yiu Pong Chan, Mr. Steve Hsien-Chieng Hsia and Mr. Benjamin Changqing Ye as independent directors.
