This announcement is not for release, publication, distribution, directly or indirectly, in or into the United States (including its territories and possessions, any state of the United States and the District of Columbia). This announcement does not constitute or form a part of any offer or solicitation to purchase or subscribe for securities in the United States or in any other jurisdictions. The securities mentioned herein have not been, and will not be, registered under the United States Securities Act of 1933 as amended from time to time (the “U.S. Securities Act”) or securities law of any state or other jurisdiction of the United States. The securities may not be offered, sold, pledged or otherwise transferred within the United States except pursuant to an exemption from the registration requirements of the U.S. Securities Act and in compliance with any applicable state securities laws. The securities are being offered and sold outside the United States in offshore transactions in accordance with Regulation S under the U.S. Securities Act. There will be no public offer of securities in the United States.

This announcement is for information purposes only and does not constitute an invitation or offer to acquire, purchase or subscribe for securities. This announcement is not a prospectus. Potential investors should read the prospectus dated August 11, 2025 (the “Prospectus”) issued by SICC Co., Ltd. (山東天岳先進科技股份有限公司) (the “Company”) for detailed information about the Global Offering described below before deciding whether or not to invest in the H Shares thereby being offered. Any investment decision in relation to the Offer Shares should be taken solely in reliance on the information in the Prospectus. The Company has not been and will not be registered under the U.S. Investment Company Act of 1940, as amended.

Unless otherwise defined in this announcement, capitalized terms used herein shall have the same meanings as those defined in the Prospectus.

In connection with the Global Offering, China International Capital Corporation Hong Kong Securities Limited, as stabilizing manager (the “Stabilizing Manager”) (or its affiliates or any person acting for it), on behalf of the Underwriters, the extent permitted by the applicable laws and regulatory requirements of Hong Kong or elsewhere, may over-allocate or effect transactions with a view to stabilizing or supporting the market price of the H Shares at such price, in such amounts and in such manners as the Stabilizing Manager, its affiliates or any person acting for it may determine and 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 Stabilization Manager (or its affiliates or any person acting for it) and in what the Stabilizing Manager reasonably regards as the best interest of our Company, (b) may be discontinued at any time and (c) is required to be brought to an end within 30 days of the last day for lodging applications under the Hong Kong Public Offering (which is Sunday, September 14, 2025). Such stabilizing 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 be aware 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 the 30th day after the last day for lodging applications under the Hong Kong Public Offering (which is Sunday, September 14, 2025). 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.

Potential investors of the Offer Shares should note that the Sponsor-OC (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 section headed “Underwriting — Underwriting Arrangements and Expenses — Hong Kong Public Offering — 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 Wednesday, August 20, 2025).
