Listing Rules for Stocks and other relevant business rules, the Company submitted an application
to the Shenzhen Stock Exchange (hereinafter referred to as the "SZSE") for the voluntary delisting
of its shares on November 26, 2025, and received the SZSE's "Letter of Acceptance for the
Application for the Voluntary Delisting of Hangzhou Turbine Power Group Co., Ltd. Shares"
(No.354[2025] Company Department Letter) on December 2, 2025. According to this letter, the
SZSE has officially accepted the Company's application for voluntary delisting of its shares.
     According to the relevant business rules, within fifteen trading days after accepting a
company's application, the Shenzhen Stock Exchange Listing Review Committee will form an
opinion on the review. The Shenzhen Stock Exchange will make a decision on whether to
terminate the company's stock listing based on the review opinion of the Listing Review
Committee. There is no delisting arrangement period for a company that voluntarily terminates its
listing. The company's stock will be delisted within five trading days from the date the Shenzhen
Stock Exchange announces the termination of the listing. After the stock exchange is implemented,

Company's stock is delisted, its corresponding market value will not be reflected in investors' total
account value for a period of time. Once the Company's stock is converted into Hirisun stock and
listed, the corresponding market value will be reflected in Hirisun stock. Investors are advised to
take note. The Company will disclose a delisting announcement after the Shenzhen Stock
Exchange makes the decision to delist the Company's stock.
 This announcement is hereby made.
