On November 18, Heshun Petroleum released an announcement regarding unusual stock movements. It stated that the cumulative increase in the closing price of its stock over two consecutive trading days—November 14 and November 17, 2025—exceeded 20%, indicating abnormal fluctuations in stock trading. The company plans to acquire no less than 34% of the equity in Shanghai CuniQ Integrated Circuit Design Co., Ltd. This will be achieved through a combination of equity purchase and cash capital increase. Additionally, Heshun Petroleum intends to gain collective control over 51% of the voting rights in the target company via voting rights delegation, thereby securing control over the entity. The intent agreement signed on this occasion simply reflects the initial consensus reached by both parties concerning the acquisition. The specific transaction details, including the plan and the amount, will be determined by the final formal acquisition agreement to be signed later.
