Changyuan Donggu: Abnormal fluctuations in stock trading, intending to issue shares to purchase 100% equity of Kanghao Mechanical and Electrical.

Changyuan Donggu Announcement: The closing price of the company's stock has deviated by more than 20% for three consecutive trading days on June 29, June 30, and July 1, 2026, indicating abnormal stock trading volatility. After a self-examination by the company, it has been confirmed that there are no major undisclosed information other than the previously disclosed significant asset restructuring. The significant asset restructuring involves the company's planned acquisition of 100% equity of Kanghao Mechanical and Electrical currently held by Xinyuan Power through the issuance of shares and the fundraising of matching funds. The audit, evaluation, and other related work are still ongoing, and the uncertainty remains regarding whether the transaction can be completed. In addition, the company's total shares are 324 million, of which the controlling shareholder and the ultimate controlling parties collectively hold 63.16% of the shares, resulting in a small external circulation. The turnover rate on July 1, 2026, was 5.61%, calculated based on the external circulation as 15.24%, indicating a risk of irrational speculation and sharp fluctuations in stock prices.
