LISTING RULES The Listing Rules permit companies with a primary listing on the Stock Exchange to repurchase their shares on the Stock Exchange subject to certain restrictions the most important of which are summarized below: (i) the shares to be repurchased by a company must be fully paid-up; (ii) the company has previously sent to its shareholders an explanatory statement complying with the Listing Rules; and (iii) all on market repurchase of shares by a company with its primary listing on the Stock Exchange must be approved in advance by an ordinary resolution either by way of a specific approval in relation to specific transactions or by a general mandate to the directors of the company to make such repurchase and a copy of such resolution together with the necessary documentation have been delivered to the Stock Exchange in accordance with the Listing Rules. 2. SHARE CAPITAL As of the Latest Practicable Date the issued share capital of the Company comprised 53417001 H Shares and 50151012 Unlisted Shares with a nominal value of RMB1.00 each. Subject to the passing of the special resolution granting the Repurchase Mandate and on the basis that the issued share capital of the Company remains unchanged since the Latest Practicable Date and up to the date of the AGM the Company may repurchase pursuant to the Repurchase Mandate up to a maximum of 10356801 H Shares representing 10% of the total number of issued Shares (excluding the Treasury Shares if any) as of the date of passing the resolution approving the Repurchase Mandate during the period commencing from the date of passing the resolution and until the earliest of: (a) the conclusion of the next annual general meeting of the Company; (b) the expiration of the period within which the next annual general meeting of the Company is required by the Articles of Association or by any applicable laws to be held; and (c) the date on which the authority given under the special resolution approving the Repurchase Mandate is revoked or varied by an special resolution of the Shareholders.– 18 –APPENDIX II EXPLANATORY STATEMENT RELATING TO THE REPURCHASE MANDATE 3. REASONS AND FUNDING OF THE REPURCHASE OF SHARES The Directors believe that it is in the best interests of the Company and the Shareholders as a whole to seek a general authority from the Shareholders to enable the Company to repurchase its H Shares on the Stock Exchange. Such repurchases may depending on market conditions and funding arrangements at the time lead to an enhancement of the net asset value per Share and/or its earnings per Share and will only be made when the Directors believe that such a repurchase will benefit the Company and the Shareholders as a whole.Repurchases of Shares will be financed out of funds legally available for the purpose and in accordance with the Articles of Association the Listing Rules and the applicable PRC laws and regulations.The Directors have no present intention to repurchase any Shares and they would only exercise the power to repurchase in circumstances where they consider that the repurchase would be in the best interests of the Company and the Shareholders as a whole. The Directors consider that if the Repurchase Mandate were to be exercised in full at the current prevailing market value it may not have a material adverse impact on the working capital and the gearing position of the Company as compared with the positions disclosed in the audited consolidated financial statements of the Company as of December 31 2023 being the date to which the latest published audited consolidated financial statements of the Company were made up. The number of H Shares to be repurchased on any occasion and the price and other terms upon which the same are repurchased will be decided by the Directors at the relevant time having regard to the circumstances then pertaining and in the best interest of the Company. The Directors do not propose to exercise the Repurchase Mandate to such extent as would in the circumstances have a material adverse effect on the working capital requirements of the Company or on the gearing levels which in the opinion of the Directors are from time to time appropriate for the Company. 4. TAKEOVERS CODE If as a result of a repurchase of Shares by the Company pursuant to the Repurchase Mandate a Shareholder’s proportionate interest in the voting rights of the Company increases such increase will be treated as an acquisition for the purposes of Rule 32 of the Takeovers Code. Accordingly a Shareholder or a group of Shareholders acting in concert depending on the level of increase of the Shareholder’s interest could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 and 32 of the Takeovers Code.As of the Latest Practicable Date to the best knowledge and belief of the Directors Mr. ZHANG Dalei Mr. GAO Fei Mr. CHEN Mingqiang and Beijing Airdoc Universe Technology Center L.P. (北京郁金香宇宙科技中心（有限合伙）) (‘‘Airdoc Universe’’) as a single largest group of Shareholders are able to exercise or control the exercise of voting rights attaching to a total of 24164751 Shares representing 23.3% of the total issued share capital of the Company which include (a) 17873326 Shares directly held by Mr. ZHANG – 19 –APPENDIX II EXPLANATORY STATEMENT RELATING TO THE REPURCHASE MANDATE Dailei (b) 4161908 Shares held by Airdoc Universe where Mr. Zhang Dalei served as the general partner (c) 451757 Shares directly held by Mr. GAO Fei and (d) 1677760 Shares directly held by Mr. CHEN Mingqiang.In the event that the Directors exercise the Repurchase Mandates in full the single largest group of Shareholders would be able to exercise or control the exercise of voting rights attaching to approximately 25.9% of the issued share capital of the Company. The increase would not give rise to an obligation to make a mandatory offer under Rule 26 of the Takeovers Code. Notwithstanding the foregoing the Board does not propose to exercise the Repurchase Mandates to such an extent as would give rise to an obligation to make a mandatory offer in accordance with Rule 26 of the Takeovers Code or consequences that would arise under any similar applicable law of which the Directors are aware. Moreover the Board of Directors also does not propose to exercise the Repurchase Mandates to such an extent as would result in the aggregate number of Shares held by the public Shareholders falling below the prescribed minimum percentage required by the Stock Exchange.Save as disclosed above the Directors are not aware of any consequences which will arise under either or both of the Takeovers Code and any similar applicable law as a result of any repurchases to be made under the Repurchase Mandates. 5. DIRECTORS THEIR CLOSE ASSOCIATES AND THE COMPANY’S CORE CONNECTED PERSONS None of the Directors nor to the best of their knowledge having made reasonable enquiries any of their close associates (as defined in the Listing Rules) has any present intention in the event that the Repurchase Mandate is approved by Shareholders to sell Shares to the Company. No core connected person (as defined in the Listing Rules) of the Company has notified the Company that he/she/it has any present intention to sell Shares to the Company or has undertaken not to do so in the event that the Repurchase Mandate is approved by the Shareholders. 6. UNDERTAKING OF THE DIRECTORS The Directors will exercise the power of the Company to make repurchases pursuant to the Repurchase Mandate in accordance with the Listing Rules the applicable laws of the PRC and the Articles of Association. In addition the Company has confirmed that neither the explanatory statement nor the proposed share repurchases has any unusual features. 7. SHARE REPURCHASE MADE BY THE COMPANY No repurchase of Shares (whether on the Stock Exchange or otherwise) has been made by the Company in the six months immediately preceding the Latest Practicable Date. The Company has no present intention to repurchase Shares to such extent as to result in the number of Shares held by the public being reduced to less than 25%.– 20 –APPENDIX II EXPLANATORY STATEMENT RELATING TO THE REPURCHASE MANDATE 8.
