Unless otherwise defined in this announcement, capitalized terms used herein shall have the same meanings as those defined in the Prospectus. --- page 2 --- – 2 – In connection with the Global Offering, Livermore Holdings Limited, as the stabiliz ing manager (the “Stabilizing Manager”) (or its affiliates or any person acting for it) to the extent permitted by the applicable laws and regulatory requirements of Hong Kong or elsewhere, may make purchases, over-allocate or effect transactions in the market or otherwise take such stabilizing action(s) with a view to stabilizing or supporting the market price of the H Shares at a level higher than that which might otherwise prevail for a limited period after the Listing Date. However, there is no obligation on the Stabilizing Manager (or its affiliates or any person acting for it) to conduct any such stabilizing action. Such stabilizing action, if taken, (a) will be conducted at the absolute discretion of the Stabilizing Manager (or its affiliates or any person acting for it) and in what the Stabilizing Manager reasonably regards as the best interest of the Company, (b) may be discontinued at any time and (c) is required to be brought to an end within 30 days after the last day for lodging applications under the Hong Kong Public Offering. Such stabilization action, if taken, may be effected in all jurisdictions where it is permissible to do so, in each case in compliance with all applicable laws, rules and regulatory requirements, including the Securities and Futures (Price Stabilizing) Rules (Chapter 571W of the Laws of Hong Kong), as amended, made under the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong). Potential investors should note that no stabilizing action can be taken to support the price of the H Shares for longer than the stabilization period, which will begin on the Listing Date and is expected to expire on Saturday, January 10, 2026, being the 30th day after the last day for lodging applications under the Hong Kong Public Offering. After this date, when no further stabilizing action may be taken, demand for the H Shares, and therefore the price of the H Shares, could fall. The obligations of the Hong Kong Underwriters under the Hong Kong Underwriting Agreement to subscribe for, and to procure subscribers for, the Hong Kong Offer Shares, are subject to termination by the Overall Coordinators (for themselves and on behalf of the Underwriters) if certain events shall occur prior to 8:00 a.m. on the Listing Date. Such grounds are set out in the section headed “Underwriting” in the Prospectus. It is important that you refer to that section for further details. --- page 3 --- – 3 – ʮ̡ Guoxia Technology Co., Ltd.

Potential investors should read the Prospectus dated December 8, 2025 issued by Guoxia Technology Co., Ltd. for detailed information about the Global Offering described below before deciding whether or not to invest in the Shares thereby being offered. * Potential investors of the Offer Shares should note that the Joint Representatives (for themselves and on behalf of the Hong Kong Underwriters) shall be entitled to terminate their obligations under the Hong Kong Underwriting Agreement with immediate effect upon the occurrence of any of the events set out in the paragraph headed “Underwriting – Underwriting Arrangements and Expenses – Hong Kong Public Offering – Hong Kong Underwriting Agreement – Grounds for Termination” in the Prospectus at any time prior to 8:00 a.m. (Hong Kong time) on the Listing Date (which is currently expected to be on December 16, 2025). --- page 17 --- – 17 – OTHER INFORMATION Offer Size Adjustment Option The Offer Size Adjustment Option has been fully exercised by the Company, pursuant to which the Company is issuing and allotting 5,077,900 additional Offer Shares, representing approximately 15% of the total number of Offer Shares initially available under the Global Offering, at the Offer Price. All of the additional Offer Shares that would be allotted and issued by the Company pursuant to the full exercise of the Offer Size Adjustment Option will be allocated to the International Offering. Accordingly, the total number of Offer Shares finally available under the Global Offering (taking into account the full exercise of the Offer Size Adjustment Option and before any exercise of the Over-allotment Option) that would be allotted and issued by the Company is 35,545,500 Offer Shares and the total issued share capital of the Company upon Listing (taking into account the full exercise of the Offer Size Adjustment Option and before any exercise of the Over-allotment Option) will be 511,871,975 Shares. As a result of the above, the final number of Offer Shares under the International Offering is adjusted to 35,545,500 Shares, representing approximately 91.30% of the total number of Offer Shares under the Global Offering (assuming the Over-allotment Option is not exercised). PUBLIC FLOAT AND FREE FLOAT Immediately after the completion of the Global Offering, 9 1,263,740 H Shares, representing approximately 17.8% of the issued share capital of our Company (before any exercise of the Over-allotment Option) will count towards the public float. Therefore, the number of H shares held in public hands is higher than the prescribed percentage of H Shares required to be held in public hands of 1 5.0% under Rule 19A.13A(1) of the Listing Rules, satisfying the minimum percentage requirement in compliance with Rule 19A.13A(1) of the Listing Rules. Based on the Offer Price of HK$20.1 per H Share, the Company satisfies the free float requirement under Rule 19A.13C(1)(b) of the Listing Rules. --- page 18 --- – 18 – The Directors confirm that, immediately following completion of the Global Offering: (i) the Shares will be held by at least 300 Shareholders at the time of Listing, in compliance with Rule 8.08(2) of the Listing Rules; (ii) the three largest public Shareholders will not hold more than 50% of the H Shares held in public hands at the time of Listing, in compliance with Rules 8.08(3) and 8.24 of the Listing Rules; (iii) no placee will, individually, be placed more than 10% of the enlarged issued share capital of the Company immediately after the Global Offering; and (iv) there will not be any new substantial Shareholder (as defined in the Listing Rules) immediately after the Global Offering. COMMENCEMENT OF DEALINGS The H Share certificates will only become valid evidence of title at 8:00 a.m. (Hong Kong time) on Tuesday, December 16, 2025, provided that (i) the Global Offering has become unconditional in all respects, and (ii) the right of termination described in the section headed “Underwriting – Underwriting Arrangements and Expenses – Hong Kong Public Offering – Hong Kong Underwriting Agreement – Grounds for termination” in the Prospectus has not been exercised. Investors who trade H Shares prior to the receipt of H Share certificates or the H Share certificates becoming valid evidence of title do so entirely at their own risk. Assuming that the Global Offering becomes unconditional at or before 8:00 a.m. (Hong Kong time) on Tuesday, December 16, 2025, it is expected that dealings in the H Shares on the Stock Exchange will commence at 9:00 a.m. on Tuesday, December 16, 2025. The H Shares will be traded in board lots of 100 H Shares each and the stock code of the H Shares will be 2655. By order of the Board Guoxia Technology Co., Ltd.
