APPENDIX II

EXPLANATORY STATEMENT

This Appendix serves as an explanatory statement, as required by the Listing Rules, to provide the requisite information to enable you to make an informed decision on whether to for, against or abstain from the special resolution to grant to the Board the Repurchase General Mandate.

LISTING RULES RELATING TO THE REPURCHASE OF SECURITIES

The Listing Rules permit companies with a primary listing on the Stock Exchange to repurchase their securities on the Stock Exchange subject to certain restrictions, the most important of which are summarised below. The Company is empowered by the Articles of Association to repurchase its securities.

REGISTERED CAPITAL

As of the Latest Practicable Date, the registered capital of the Company was RMB133,333,400, including 100,000,000 Unlisted Shares and 33,333,400 H Shares of RMB1.00 each, and the Company did not hold any treasury Shares. Subject to the passing of the proposed resolution granting the Repurchase General Mandate and on the basis that no Shares will be allotted, issued or repurchased by the Company on or prior to the date of the AGM, the Company will be allowed to repurchase a maximum of 3,333,340 H Shares under the Repurchase General Mandate, being the maximum of 10% of the number of the issued H Shares (excluding treasury Shares) as at the date of passing of the relevant resolution.

REASONS FOR REPURCHASE

The Directors consider that the Repurchase General Mandate is in the interests of the Company and the Shareholders as a whole. The repurchase of H Shares will only be exercised by the Company when the Board believes that such repurchase will benefit the Company and its Shareholders. When exercising the Repurchase General Mandate, the Directors may, subject to market conditions and the Company's capital management needs at the relevant time of the repurchase, decide to cancel the H Shares repurchased following settlement of any such repurchase or hold such H Shares as treasury Shares. The cancellation of the H Shares repurchased may, depending on the market conditions and funding arrangements at the time, lead to an enhancement of the net asset value per Share and/or earnings per Share. On the other hand, the H Shares repurchased and held by the Company as treasury shares may be resold on the market at market prices to raise funds for the Company, or transferred or used for other purposes (including but not limited to being used as shares subject to the share incentive plan as approved from time to time at the general meeting of the Company), subject to compliance with the Articles of Association, the Listing Rules, the applicable securities regulatory rules in Hong Kong, and other relevant laws, regulations, and normative documents.

APPENDIX II

EXPLANATORY STATEMENT

FUNDING OF REPURCHASE

In repurchasing H Shares, the Company may only apply funds legally available for such purpose in accordance with the Articles of Association, the Listing Rules and the applicable laws, regulations and rules of the PRC, which includes the funds from the Company's internal resources.

Taking into account the current good working capital position of the Company, the Directors consider that, if the Repurchase General Mandate were to be exercised in full, it would not have a material adverse effect on the working capital and/or the gearing position of the Company (as compared with its financial position as of 31 December 2025 as disclosed in the latest published audited accounts contained in the 2025 Annual Report). However, the Directors do not propose to repurchase H Shares to such an extent as would, in the circumstances, have a material adverse effect on the working capital requirements of the Company or the gearing levels which in the opinion of the Directors are from time to time appropriate for the Company. The number of Shares to be repurchased on any occasion, the price, time 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 prevailing, in the best interests of the Company and the Shareholders as a whole.

STATUS OF THE REPURCHASED SHARES

According to the Listing Rules, if the Company repurchases any Shares pursuant to the Repurchase General Mandate, the Company will either (i) cancel the Shares repurchased and/or (ii) hold such Shares in treasury, subject to market conditions and the Company's capital management needs at the relevant time any repurchases of such Shares are made.

Since the laws of the Company's place of incorporation (i.e. the PRC) do not require treasury Shares to be held in the Company's name, shareholders' rights attached to the shares will be suspended under the laws once the shares are repurchased by the issuer irrespective of whether they are held in the name of the Company or its nominee. In such case, the Company may continue to hold the repurchased shares as treasury shares in a segregated account in CCASS. To the extent that any repurchased shares are deposited in CCASS, the Company will, upon completion of the share repurchase, give clear written instructions to its share registrar and the relevant broker to update the record to clearly identify those repurchased shares held in CCASS as treasury Shares.

GENERAL

The Directors will exercise the power of the Company to make repurchases pursuant to the Repurchase General Mandate and in accordance with the Listing Rules, the Articles of Association and the applicable laws, regulations and requirements of the PRC.

None of the Directors nor, to the best of their knowledge having made all reasonable enquiries, their close associates (as defined in the Listing Rules), have any present intention to sell any H Shares to the Company if the Repurchase General Mandate is approved at the AGM, respectively.

No core connected persons (as defined in the Listing Rules) of the Company have notified the Company that they have an intention to sell any Shares held by them to the Company, or have undertaken not to do so, in the event that the Repurchase General Mandate is approved.

APPENDIX II
EXPLANATORY STATEMENT

Neither the explanatory statement nor the proposed share repurchase has any unusual features.

DISCLOSURE OF INTEREST

If a Shareholder’s proportionate interest in the voting rights of the Company increases on the Company exercising its powers to repurchase Shares pursuant to the Repurchase General Mandate, such increase will be treated as an acquisition for the purposes of the Takeovers Code. Accordingly, a Shareholder or a group of Shareholders acting in concert could obtain or consolidate control of the Company and become obliged to make a mandatory offer in accordance with Rule 26 of the Takeovers Code.

As of the Latest Practicable Date, to the best knowledge and belief of the Directors, Space Technology (Beijing) Co., Ltd. (空格科技(北京)有限公司), Beijing Tongda Chengye Technology Center (Limited Partnership) (北京通達成業科技中心(有限合夥)), Mr. Hu Dalin, Ms. Ma Lei and Mr. He Feng were a group of controlling Shareholders of the Company (“Controlling Shareholder Group”) pursuant to the Listing Rules, controlling approximately 34.08% of the total issued share capital of the Company. In the event that the Board exercised in full the power to repurchase H Shares in accordance with the terms of the Repurchase General Mandate, the total interests of the Controlling Shareholder Group in the total issued share capital of the Company would increase to approximately 34.95%. The Board is not aware of any consequences which will arise under the Takeovers Code and/or any similar applicable law, as a result of any purchases to be made under the Repurchase General Mandate. As at the Latest Practicable Date, the public float of the Company is below the relevant prescribed minimum percentage as required by the Stock Exchange. The Directors will not repurchase H Shares if the public float of the Company is below the relevant prescribed minimum percentage as required by the Stock Exchange or if such repurchase would result in the public float of the Company falling below the relevant prescribed minimum percentage as required by the Stock Exchange.

SECURITIES REPURCHASE MADE BY THE COMPANY

The Company did not repurchase any Shares (whether on the Stock Exchange or otherwise) in the previous six months preceding the Latest Practicable Date.
