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.

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 Saturday, September 13, 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 Saturday, September 13, 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 Tuesday, August 19, 2025).

THE LISTING APPLICATION

We have applied to the Stock Exchange for the granting of listing of, and permission to deal in, our H Shares to be issued pursuant to the Global Offering (including any H Shares which may be issued pursuant to the exercise of the Over-allotment Option).

STRUCTURE OF THE GLOBAL OFFERING

The Global Offering comprises:

• the Hong Kong Public Offering of initially 2,387,300 H Shares (subject to reallocation) representing approximately 5% of the total number of Offer Shares initially available under the Global Offering, and
• the International Offering of initially 45,358,400 H Shares (subject to reallocation and the Over-allotment Option) representing approximately 95% of the total number of Offer Shares initially available under the Global Offering.

The allocation of the Offer Shares between the Hong Kong Public Offering and the International Offering will be subject to reallocation as described in the section headed "Structure of the Global Offering" in the Prospectus.

In accordance with Chapter 4.14 of the Guide, if (i) the International Offering is not fully subscribed and the Hong Kong Public Offering is fully subscribed or oversubscribed irrespective of the number of times; or (ii) the International Offering is fully subscribed or oversubscribed and the Hong Kong Public Offering is fully subscribed or oversubscribed with the number of Offer Shares validly applied for in the Hong Kong Public Offering representing less than 15 times of the number of Offer Shares initially available for subscription under the Hong Kong Public Offering, the Sponsor-OC have the authority to reallocate International Offer Shares originally included in the International Offering to the Hong Kong Public Offering in such number as they deem appropriate, provided that the total number of Offer Shares available under the Hong Kong Public Offering following such reallocation shall be not more than 4,774,600 Offer Shares (representing twice of the number of the Offer Shares initially available under the Hong Kong Public Offering).

In addition, in connection with the Global Offering, the Company is expected to grant to the International Underwriters the Over-allotment Option, exercisable by the Sponsor-OC on behalf of the International Underwriters at any time from the Listing Date until 30 days after the last day for lodging applications under the Hong Kong Public Offering, pursuant to which the Company may be required to issue up to an aggregate of 7,161,800 additional H Shares, representing approximately 15% of the number of Offer Shares available under the Global Offering, at the Offer Price, to cover over-allocations in the International Offering, if any.

---

If the Over-allotment Option is exercised in full, the additional Offer Shares to be issued pursuant thereto will represent approximately 1.5% of the enlarged issued share capital of the Company immediately following the completion of the Global Offering. If the Over-allotment Option is exercised, an announcement will be made by the Company on the website of the Stock Exchange at www.hkexnews.hk and on the Company's website at https://www.sicc.cc, respectively.

PRICING

We will determine the Offer Price by reference to, among other factors, the closing price of the A Shares on the Shanghai Stock Exchange on the last trading day on or before the Price Determination Date, and the Offer Price will not be more than HK$42.80, unless to be otherwise announced as further explained in the section headed "Structure of the Global Offering" in the Prospectus. Applicants for the Hong Kong Offer Shares are required to pay, on application (subject to application channel), the maximum Offer Price of HK$42.80 per Offer Share plus brokerage of 1.0%, SFC transaction levy of 0.0027%, AFRC transaction levy of 0.00015% and Stock Exchange trading fee of 0.00565%, subject to refund if the Offer Price as finally determined is less than HK$42.80 per Offer Share.
