China Suntien Green Energy Corporation Limited disclosed that Hebei Guofu Equity Investment Fund Management Co., Ltd. (Guofu Fund), an indirect subsidiary of controlling shareholder Hebei Construction & Investment Group (HECIC), has launched a 12-month share-purchase programme via the Shanghai Stock Exchange Southbound channel. The plan allows Guofu Fund to buy up to 0.50% of the company’s total issued share capital for a total consideration between RMB15.00 million and RMB30.00 million.

On 16 June 2026, Guofu Fund executed the first tranche of the programme, acquiring 3.01 million H shares for approximately RMB9.02 million. The purchase lifted Guofu Fund’s stake from 0% to 0.0667% of China Suntien’s total issued shares.

Including this transaction, HECIC and its subsidiaries now control 2.37 billion shares—comprising 2.06 billion A shares and 310.01 million H shares—equivalent to 52.4931% of the company’s issued share capital, up from the previous 52.43%.

Guofu Fund has pledged not to reduce its holdings during the 12-month accumulation period and for six months after completion. The company cautioned that the plan could be delayed or halted subject to market conditions and will release timely updates in line with disclosure requirements.
