The estimated audit fee has been determined after due consideration and arm's length negotiations between the Company and KPMG. Having considered potential new audit matters for 2026, as well as the increase in audit procedures resulting from the expansion of the Company's asset size, revenue and client base, the audit fee is not expected to exceed RMB3.5 million for the financial year ending December 31, 2026, and it is proposed that the general meeting authorize the Board to determine the specific amount of such remuneration.

APPENDIX I

EXPLANATORY STATEMENT RELATING TO SHARE REPURCHASE MANDATE

The following explanatory statement is required under the Listing Rules to provide Shareholders with information reasonably necessary to enable them to make an informed decision on whether to vote for or against the special resolution to be proposed at the AGM in relation to the grant of the Share Repurchase Mandate.

  1. REGISTERED CAPITAL

As at the Latest Practicable Date, the registered capital of the Company was RMB915,100,653, comprising 389,559,466 Domestic Unlisted Shares and 525,541,187 H Shares with a par value of RMB1.00 each.

Subject to the passing of the special resolution for the granting of the Share Repurchase Mandate at the AGM and on the basis that the issued share capital of the Company remains unchanged as at the date of the AGM (i.e. 389,559,466 Domestic Unlisted Shares and 525,541,187 H Shares), the Directors will be allowed to repurchase, pursuant to the Share Repurchase Mandate, during the period in which the Share Repurchase Mandate remains in force a total of 52,554,118 H Shares, representing 10% of the total number of H Shares in issue (excluding any treasury shares) as at the date of the AGM.

  1. REASONS FOR REPURCHASE

The Directors believe that the grant of the Share Repurchase Mandate is in the best interests of the Company and the Shareholders. Depending on the prevailing market conditions and funding arrangements, such repurchases may enhance net asset value per share and/or earnings per share and will only be made if the Directors consider such repurchases beneficial to the Company and the Shareholders.

  1. FUNDS FOR SHARE REPURCHASE

The Company may only use funds that may lawfully be used for the repurchase of Shares under its Articles of Association, China laws and/or any other applicable laws, as the case may be.

  1. EFFECT OF SHARE REPURCHASE

The Share Repurchase Mandate, if exercised in full at any time during the proposed Repurchase Period, may have a material adverse effect on the working capital or balance sheet position of the Company as compared to the position disclosed in the audited accounts of the Company in its annual report for the year ended December 31, 2025. However, the Directors do not intend to exercise the Share Repurchase Mandate in circumstances where the exercise of the Share Repurchase Mandate would have a material adverse effect on the working capital requirements of the Company or on the balance sheet position of the Company which, in the opinion of the Directors, are appropriate.

  • 10 -

APPENDIX I

EXPLANATORY STATEMENT RELATING TO SHARE REPURCHASE MANDATE

The Company will cancel any repurchased shares and/or hold the repurchased shares as treasury shares depending on the circumstances at the time of the repurchases, such as market conditions and its capital management requirements.

5. PRICE OF H SHARES

The highest and lowest prices per H Share traded on the Stock Exchange during the twelve months preceding and up to the Latest Practicable Date are as follows:

| Month | Highest
HK$ | Lowest
HK$ |
| --- | --- | --- |
| 2025 | | |
| April | 46.90 | 31.60 |
| May | 44.20 | 34.00 |
| June | 39.10 | 34.10 |
| July | 48.50 | 36.10 |
| August | 94.50 | 43.30 |
| September | 106.10 | 82.20 |

| March | 67.95 | 48.86 |
| April (up to the Latest Practicable Date) | 70.95 | 51.20 |

6. GENERAL

To the best knowledge of the Directors having made all reasonable enquiries, neither the Directors nor any of their respective close associates (as defined in the Listing Rules) have any current intention to sell any H Shares to the Company if the grant of the Share Repurchase Mandate is approved by the Shareholders.

The Company has not received notification from any of the core connected persons (as defined in the Listing Rules) of the Company that they currently intend to sell any H Shares to the Company, or have undertaken not to sell any H Shares held by them to the Company, subject to the Shareholders' approval of the grant of the Share Repurchase Mandate.


APPENDIX I

EXPLANATORY STATEMENT RELATING TO SHARE REPURCHASE MANDATE

The Directors will exercise the power of the Company to repurchase Shares under the Share Repurchase Mandate in compliance with the Listing Rules and applicable laws and regulations of China. To the best knowledge of the Directors, there is nothing unusual about this explanatory statement and the Share Repurchase Mandate.

7. TAKEOVERS CODE

If the repurchase of H Shares under the Share Repurchase Mandate results in an increase in a Shareholder's proportionate interest in the voting rights of the Company, such increase will be treated as an acquisition of voting rights for the purposes of the Takeovers Code. Accordingly, a shareholder or a group of shareholders acting in concert (as defined in the Takeovers Code) may acquire or consolidate control of the Company (depending on the level of increase in shareholders' interest) and thus be required to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

To the best knowledge of the Company, as at the Latest Practicable Date, Dr. Weiwei Luo was interested in 282,780,412 Shares representing approximately 30.90% of the total number of issued Shares of the Company. If the Directors exercise the proposed Share Repurchase Mandate, Dr. Weiwei Luo's total shareholding will increase to approximately 32.78% of the issued share capital of the Company. The Directors are not aware of any consequences that may give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code.

The Directors do not intend to exercise the Share Repurchase Mandate in circumstances where such exercise would result in an obligation to make a mandatory offer pursuant to Rule 26 of the Takeovers Code and/or in the aggregate number of Shares held by the public falling below the specified minimum percentage as required by the Stock Exchange.

8. SHARES REPURCHASED BY THE COMPANY

During the six months prior to the Latest Practicable Date, the Company has not repurchased any Shares on the Stock Exchange or elsewhere.
