Such stabilizing action, if taken, (a) will be conducted at the absolute discretion of the Stabilizing Manager (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 (which is Wednesday, February 4, 2026).

To the best of CICC FT’s knowledge having made all reasonable inquiries, each of the CICC FT Ultimate Clients (Gaoyi) is an independent third party of CICC FT, CICCHKS and the companies which are members of the same group of CICCHKS, and no single ultimate beneficial owner holds 30% or more interests in each of the CICC FT Ultimate Clients (Gaoyi). (2) CICC FT and China International Capital Corporation Limited will enter into a series of cross border delta-one OTC swap transactions (collectively, the “ CICC FT OTC Swaps ”) with each other and the ultimate clients (the “ CICC FT Underlying Clients”), pursuant to which CICC FT will hold the Offer Shares on a non-discretionary basis to hedge the CICC FT OTC Swaps while the economic risks and returns of the underlying Offer Shares are passed to the CICC FT Underlying Clients, subject to customary fees and commissions.

(3) PRC investors are currently not permitted under applicable PRC laws to participate directly in initial public offerings (“IPOs”) in Hong Kong. However, PRC investors are permitted to invest in products issued by appropriate domestic securities firms licensed to undertake cross-border derivatives trading activities. In connection with such products, the licensed domestic securities firms, through their Hong Kong affiliates, may participate in Hong Kong IPOs either as placees or cornerstone investors (the “ Cross-border Derivatives Trading Regime ”). Huatai Securities, the shares of which are listed on both the Shanghai Stock Exchange (stock code: 601688) and the Stock Exchange (stock code: 6886), is one of the domestic securities firms licensed to undertake cross-border derivatives trading activities. Huatai Securities entered into an ISDA agreement (the “ ISDA Agreement ”) with its indirectly wholly-owned --- page 28 --- 28 subsidiary, Huatai Capital Investment Limited (“ HTCI”) to set out the principal terms of any future total return swap between Huatai Securities and HTCI. HTFH is the one of the Overall Coordinators and Underwriters in connection with the Global Offering. Pursuant to the ISDA Agreement, HTCI, which intends to participate in the Global Offering as a placee, will hold the beneficial interest of the Offer Shares on a non-discretionary basis as the single underlying holder under a back-to-back total return swap (the “ Back-to-back TRS ”) to be entered by HTCI in connection with a Client TRS (as defined below) placed by and fully funded (i.e. with no financing provided by HTCI) by the Huatai Onshore Ultimate Clients (as defined below), by which, HTCI will, subject to customary fees and commissions, pass the full economic exposure of the Offer Shares ultimately to the Huatai Onshore Ultimate Clients, which in effect, HTCI will hold the beneficial interest of the Offer Shares on behalf of the Huatai Onshore Ultimate Clients. HTFH, the Overall Coordinator and Underwriter, and HTCI are indirectly wholly-owned subsidiaries of Huatai Securities. Accordingly, HTCI is considered as a “connected client” of HTFH pursuant to paragraph 13(7) of the Placing Guidelines. Pursuant to the Cross-border Derivatives Trading Regime, the onshore investors (the “ Huatai Onshore Ultimate Clients ”) cannot directly subscribe for the Offer Shares but may invest in derivative products issued by domestic securities firms licenced to undertake cross-border derivatives trading activities, such as Huatai Securities, with the Offer Shares as the underlying assets. Instead of directly subscribing for the Offer Shares, the Huatai Onshore Ultimate Clients, through their respective investment managers as applicable, will place a total return swap order (the “ Client TRS ”) with Huatai Securities in connection with the Company’s IPO and Huatai Securities will place a Back-to-back TRS order to HTCI on the terms of the ISDA Agreement. In order to hedge its exposure under the Back-to-back TRS, HTCI participates in the Company’s IPO and subscribes the Offer Shares through placing order with HTFH during the International Offering. The purpose of HTCI to subscribe for the Offer Shares is for hedging the Back-to-back TRS in connection with the Client TRS order placed by the Huatai Onshore Ultimate Clients. Pursuant to the terms of the contracts of the Back-to-back TRS and the Client TRS, during the tenor of the Back-to-back TRS and the Client TRS, subject to customary fees and commissions, all economic returns of the Offer Shares will be ultimately passed to the Huatai Onshore Ultimate Clients through the Back-to-back TRS and the Client TRS and all economic loss shall be ultimately borne by the Huatai Onshore Ultimate Clients. HTCI will not take any economic return or bear any economic loss in relation to the Offer Shares. Investment in the Back-to-back TRS and the Client TRS is similar to the investment in a qualified domestic institutional investor fund (“ QDII”) in the way that the Huatai Onshore Ultimate Clients would reap all the economic benefits of the underlying Offer Shares, except that a QDII fund would pass through the exchange rate exposure on both the notional value of the investment and the profit and loss of the investment. In contrast, the profit and loss of the Back-to-back TRS and the Client TRS factor into account the fluctuation in RMB exchange rate upon termination of the Client TRS by converting the profit and loss using the current exchange rate at the time of termination. As such, the Huatai Onshore Ultimate Clients would bear the exchange rate exposure of the profit and loss on settlement date. The Huatai Onshore Ultimate Clients may exercise an early termination right to terminate the Client TRS at its own discretion. Upon the termination upon maturity or early termination of the Client TRS by the Huatai Onshore Ultimate Clients, HTCI will dispose the Offer Shares on the secondary market and the Huatai Onshore Ultimate Clients will receive a final settlement amount in cash in accordance with the terms and conditions of the Back-to-back TRS and the Client TRS which should have taken into account all the economic returns or economic loss in relation to the Offer Shares. If upon the maturity of the Client TRS, the Huatai Onshore Ultimate Clients intend to extend the investment period, subject to further agreement between Huatai Securities and the relevant Huatai Onshore Ultimate Clients, the term of the Client TRS could be extended by way of a new issuance or a tenor extension. Accordingly, Huatai Securities will extend the term of the Back-to- back TRS by way of a new issuance or a tenor extension. It is proposed that HTCI will hold the legal title and the voting right of the Offer Shares by itself, and pass through the economic exposure to the Huatai Onshore Ultimate Clients, each being an onshore client who places a Client TRS order with Huatai Securities in connection with the IPO of the Company. HTCI will not exercise the voting right of the Offer Shares during the tenor of the Back-to-back TRS. During the life of the Client TRS and Back-to-back TRS, HTCI may continue to hold the Offer Shares in its custodian account, or to hold some or all of the Offer Shares in a prime brokerage account for stock borrowing purposes, where HTCI will lend out its holding of underlying Offer Shares in the form of stock borrowing loans consistent with market practice to lower its finance costs, provided that HTCI has the ability to call back the Offer Shares on loan at any time in order to satisfy its obligations under the Back-to-back TRS to ensure the economic interests are ultimately passed to the Huatai Onshore Ultimate Clients. --- page 29 --- 29 HTCI will purchase and hold the Offer Shares on a non-discretionary basis in accordance with the instruction from and for and on behalf of its underlying clients (the “ HTCI Underlying Clients ”), namely (i) Beijing Yuanfeng Private Equity Fund Management Partnership (Limited Partnership) (၍ଣΥྫΆุ (Υྫ )) (“ Beijing Yuanfeng”). None of ultimate beneficial owners holds an interest of 30% or more in Beij ing Yuanfeng .

None of ultimate beneficial owners holds an interest of 30% or more in Shanghai Rongyu. The largest limited partner of Beijing Yuanfeng is Hangzhou Xinyu Youxuan Investment Management Partnership Enterprise (Limited Partnership) (Υྫ ) (“Hangzhou Xinyu ”), holding approximately 91% partnership. None of ultimate beneficial owners holds an interest of 30% or more in Hangzhou Xinyu; (ii) Daohe Chengguang Private Equity Securities Investment Fund (Έ ږ“( ) Daohe Chengguang ”). The fund manager of Daohe Chengguang is Shanghai Daohe Private Equity Fund Management Co., Ltd. (ʮ̡ ), which is controlled as to 65% by Zhao Bin (Ⴛⅳ ), 21% by Li Jianan ( ҽԳӲ ) and 14% by Tong Bo (تiii) Zhongke Chuangxing Technology Investment Co., Ltd. (ʮ̡ ). Except for Mi Lei ( Ϸᆾ ), none of the ultimate beneficial owners of Zhongke Chuangxing Technology Investment Co., Ltd. holds an interest of 30% or more. To the best of HTFH’s knowledge and after making all reasonable enquiries, each of the Huatai Onshore Ultimate Clients is an independent third party of (i) the Company, the connected person or the associates thereof, and (ii) HTCI, HTFH and the companies which are members of the same group of HTCI. (4) HTFH is one of the Overall Coordinators and Underwriters in connection with the Global Offering. Pursuant to an ISDA Agreement, HTCI, which intends to participate in the Global Offering as a placee, will hold the beneficial interest of the Offer Shares on a non-discretionary basis as the single underlying holder under a back-to-back total return swap (the “Back-to-back TRS ”) to be entered by HTCI in connection with a Client TRS (as defined below) placed by and fully funded (i.e. with no financing provided by HTCI) by the Huatai Offshore Ultimate Client (as defined below), by which, HTCI will, subject to customary fees and commissions, pass the full economic exposure of the Offer Shares to the Huatai Offshore Ultimate Client, which in effect, HTCI will hold the beneficial interest of the Offer Shares on behalf of the Huatai Offshore Ultimate Client. Accordingly, HTCI is considered as a “connected client” of HTFH pursuant to paragraph 13(7) of the Placing Guidelines. The offshore investor (the “ Huatai Offshore Ultimate Client ”), through its respective investment manager, will place a total return swap order (the “ Client TRS ”) with HTCI in connection with the Company’s IPO. In order to hedge its exposure under the Client TRS, HTCI participates in the Company’s IPO and subscribes the Offer Shares through placing order with HTFH during the International Offering. The purpose of HTCI to subscribe for the Offer Shares is for hedging the Client TRS order placed by the Huatai Offshore Ultimate Client. Pursuant to the terms of the Client TRS, during the tenor of the Client TRS, subject to customary fees and commissions, all economic returns of the Offer Shares will be ultimately passed to the Huatai Offshore Ultimate Client through the Client TRS and all economic loss shall be ultimately borne by the Huatai Offshore Ultimate Client. HTCI will not take any economic return or bear any economic loss in relation to the Offer Shares. The Huatai Offshore Ultimate Client may exercise an early termination right to terminate the Client TRS at any time from the issue date of the Client TRS which should be on or after the date on which the Offer Shares are listed on the Stock Exchange at their own discretion. Upon the termination upon maturity or early termination of the Client TRS by the Huatai Offshore Ultimate Client, HTCI will dispose the Offer Shares on the secondary market and the Huatai Offshore Ultimate Client will receive a final settlement amount of the Client TRS in cash in accordance with the terms and conditions of the Client TRS which should have taken into account all the economic returns or economic loss in relation to the Offer Shares. If upon the maturity of the Client TRS, the Huatai Offshore Ultimate Client intends to extend the investment period, subject to further agreement between HTCI and the relevant Huatai Offshore Ultimate Client, the term of the Client TRS could be extended by way of a new issuance or a tenor extension. It is proposed that HTCI will hold the legal title and the voting right of the Offer Shares by itself, and pass through the economic exposure to the Huatai Offshore Ultimate Client, being the client who places a Client TRS order with HTCI in connection with the IPO of the Company. HTCI will not exercise the voting right of the Offer Shares during the tenor of the Client TRS. During the life of the Client TRS, HTCI may continue to hold the Offer Shares in its custodian account, or to hold some or all of the Offer Shares in a prime brokerage account for stock borrowing purposes, where HTCI will lend out its holding of underlying Offer Shares in the form of stock borrowing loans consistent with market practice to lower its finance costs, provided that HTCI has the ability to call back the Offer Shares on loan at any time in order to satisfy its obligations under the Client TRS to ensure the economic interests are ultimately passed to the Huatai Offshore Ultimate Client. --- page 30 --- 30 HTCI will purchase and hold the Offer Shares on a non-discretionary basis in accordance with the instruction from and for and on behalf of its underlying client (the “ HTCI Underlying Client ”), namely KSICN SPC SUB KSICN SP2. Except for Zhu Lei, none of the ultimate beneficial owners of KSICN SPC SUB KSICN SP2 holds an interest of 30% or more. To the best of HTFH’s knowledge and after making all reasonable enquiries, the Huatai Offshore Ultimate Client is an independent third party of (i) the Company, the connected person or the associates thereof, and (ii) HTCI, HTFH and the companies which are members of the same group of HTCI. (5) It is proposed that GTJAI participates as placee to subscribe for the Offer Shares under the International Offering (the “GTJAI Subscription ”). In relation to the GTJAI Subscription, GTJAI shall hold the Offer Shares for hedging purpose as the single underlying asset of several sets of back-to-back total return swap transaction (the “ GTHT Back-to-back TRS ”) to be entered into between GTJAI and Guotai Haitong Securities Co., Ltd. (the “ GTHT Onshore Parent ”) in connection with several total return swap orders (the “ GTHT Client TRS ”) to be entered into by GTHT Onshore Parent and several underlying clients (the “GTHT Onshore Underlying Clients ”), respectively.
