AND

(4) NOTICE OF AGM

I. INTRODUCTION

The purposes of this circular are, among other things, (1) to provide you with further information in relation to the proposed grant of general mandate to the Board to issue Shares, the Proposed Issuance and the Authorisation on the Provision of Guarantees; and (2) to give you notice of the AGM, to enable you to make an informed decision on whether to vote for or against the resolutions at the AGM.

LETTER FROM THE BOARD

II. GENERAL MANDATE TO ISSUE SHARES

In order to ensure flexibility and to give discretion to the Board in the event that it becomes desirable to issue any Shares, a special resolution will be proposed at the AGM to give an unconditional general mandate to the Board, to separately or concurrently, allot, issue, and deal with additional A Shares and H Shares to make or grant offers, agreements or options in respect thereof, with a total number of Shares not exceeding 20% of the total number of each of the existing A Shares and H Shares in issue as at the date of passing the relevant resolution at the AGM (the “General Mandate”), at a discount (if any) of no more than 20% to the benchmark price as required by Rule 13.36(5) of the Listing Rules.

The General Mandate will lapse until the earlier of:

(a) the conclusion of the 2023 annual general meeting of the Company;

(b) the expiration of the 12 months period following the passing of this resolution; and

(c) the revocation or variation of the authority given to the Board under this resolution by a special resolution of the Shareholders at a general meeting.

Pursuant to the relevant laws and regulations of the PRC, any additional issuance of A Shares exceeding RMB300 million and exceeding 20% of the net assets of the Company at the latest year end would still require the approval of the Shareholders at a general meeting even if the General Mandate is approved at the AGM. Given the size of the Company, issuance of A Shares not exceeding RMB300 million and not exceeding 20% of the net assets of the Company at the latest year end is not applicable to the Company, meaning that any issuance of A Shares in any amount would require prior approval from the Shareholders at a general meeting.

As at 30 April 2023, the Company had in issue 18,120,903,728 Shares, including 13,476,906,420 A Shares and 4,643,997,308 H Shares. Subject to the passing of the proposed resolution for the approval of the General Mandate and in accordance with the terms therein, the Company would be allowed to allot, issue and deal with up to a maximum of 2,695,381,284 A Shares and 928,799,461 H Shares, respectively, representing 20% of the number of A Shares and H Shares in issue, respectively, on the basis that no further A Shares and H Shares will be issued by the Company prior to the AGM.

It is also proposed at the AGM to give a conditional general mandate to the Board to increase the registered capital of the Company to reflect the issuance of Shares authorised under the General Mandate, to make such appropriate and necessary amendments to the Articles of Association as it think fit to reflect such increase in the registered capital of the Company, and to take any other action and go through any other procedure required to effect such increase in the registered capital of the Company.
