APPENDIX I

BUSINESSES TO BE CONSIDERED AT THE AGM

VI. RE-APPOINTMENT OF DOMESTIC AUDITOR OF THE COMPANY FOR THE YEAR OF 2026

The Board proposed that RSM China CPA LLP (容誠會計師事務所(特殊普通合夥)) (“RSM China”) be re-appointed as the domestic auditor of the Company for 2026 for a term of one year.

The Company preliminarily estimates that the audit fees for the year of 2026 will be approximately RMB0.42 million to RMB0.48 million (tax inclusive, including the audit fees of the Company and each of its subsidiaries). Such estimated audit fees were determined after consultation between the Company and RSM China, taking into account the complexity and business plan of the Company, the expected audit scope, audit timetable and the auditors’ resources required. These estimated audit fees are preliminary, and may be adjusted during the course of business due to changes in the scope of audit work and other related factors. Unless there are significant changes to the aforementioned basis or estimation, the final audit fee should not deviate materially from the estimated range of audit fees for 2026.

The Board proposed the general meeting to authorize the Board, which may in turn delegate the authority to the management of the Company, to determine the final audit fees for 2026.

VII. CHANGE OF AUDITOR FOR H SHARES OF THE COMPANY

Reference is made to the announcement of the Company dated 13 May 2026, in relation to the proposed change of auditor for H Shares of the Company.

Given the impending expiry of the term of RSM Hong Kong, and in order to address the Company’s overall audit requirements and enhance the coordination of domestic and overseas audit management, the Company proposes to change the auditor for H shares upon the expiry of the term of RSM Hong Kong. The Board and the audit committee of the Company (the “Audit Committee”) believe that regular review and refreshment of our audit arrangements, together with improved coordination between domestic and overseas audit work, is consistent with our commitment to maintaining a high standard of corporate governance, and is in the interests of the Company and Shareholders.

The Board has resolved on 13 May 2026, and upon the recommendation of the Audit Committee, to propose the appointment of Rongcheng (Hong Kong) CPA Limited (容誠(香港)會計師事務所有限公司) (“Rongcheng HK”) as the auditor for H Shares of the Company for 2026. The term shall commence from the conclusion of AGM until the conclusion of the next annual general meeting of the Company, subject to the approval of the Shareholders at the AGM. Rongcheng HK was initially established in 2008, and is an overseas branch of RSM China, being the Company’s domestic auditor. As of the date hereof, Rongcheng HK serves over 55 listed companies on the Stock Exchange. Its core members are mostly from the Big Four accounting firms and are familiar with Hong Kong and IFRS Accounting Standards, the Hong Kong Listing Rules, and capital market rules. Accordingly, Rongcheng HK possesses the professional competence and qualifications to serve as the auditor for H Shares of the Company.

APPENDIX I

BUSINESSES TO BE CONSIDERED AT THE AGM

The Company preliminarily estimates that the audit fees for 2026 will be approximately HK$3.8 million to HK$4.2 million (exclusive of tax). Such estimated audit fees were determined after consultation between the Company and Rongcheng HK, taking into account the complexity and business plan of the Company, the expected audit scope, audit timetable and the auditors' resources required. These estimated audit fees are preliminary, and may be adjusted during the course of business due to changes in the scope of audit work and other related factors. Unless there are significant changes to the aforementioned basis or estimation, the final audit fee should not deviate materially from the estimated range of audit fees for 2026. The Board shall propose that the general meeting authorize the Board, which may in turn delegate the authority to the management of the Company, to determine the audit fees for 2026.

RSM Hong Kong confirmed in writing that there are no matters in connection with its termination that need to be brought to the attention of the Shareholders and creditors of the Company. The Board and the Audit Committee also confirm that there is no disagreement between RSM Hong Kong and the Company, and there are no unresolved matters regarding the proposed change of auditor, nor are there any other matters that need to be brought to the attention of the Shareholders and creditors of the Company.
