Cangzhou Mingzhu Plastic Co Ltd, a prominent player in the energy equipment and services sector, has recently undergone a significant shift in its controlling ownership. The company, which is listed on the Shenzhen Stock Exchange, specializes in the production and sale of a diverse range of products, including polyethylene gas, water supply pipes and fittings, tubes, polyamide films, and lithium-ion battery separators.
On December 15, 2025, Cangzhou Mingzhu Plastic Co Ltd announced a major change in its shareholder structure. The company’s major shareholder, Dongshu Group, along with its related parties, agreed to transfer a substantial portion of its shares to Guangzhou Light Industry Co., a state-owned enterprise. This transfer encompasses more than 10% of the company’s capital and includes the assignment of voting rights. As a result, the controlling shareholder of Cangzhou Mingzhu Plastic Co Ltd is set to transition from Dongshu Group to Guangzhou Light Industry. The actual controlling entity will become the Guangzhou Municipal State-Owned Assets Supervision and Administration Commission.
This ownership restructuring is indicative of a broader trend where state entities are consolidating their stakes in key industrial firms. Such moves are often aimed at strengthening state influence and control over strategic sectors. The announcement did not include any other material corporate events or financial results.
As of December 17, 2025, the company’s close price stood at 4.79 CNY, with a 52-week high of 5.65 CNY recorded on November 16, 2025, and a 52-week low of 2.99 CNY on April 8, 2025. The market capitalization of Cangzhou Mingzhu Plastic Co Ltd is valued at 7,910,000,000 CNY, with a price-to-earnings ratio of 50.74.
This shift in ownership is expected to have implications for the company’s strategic direction and operational focus, aligning it more closely with the objectives of state-owned enterprises. Stakeholders and market observers will be closely monitoring the impact of this transition on the company’s performance and market position in the energy equipment and services industry.
