On the evening of January 30, 2026, Wanhua Chemical announced that it plans to increase the capital of its wholly-owned subsidiary, Wanhua Chemical Group (Yantai) Olefin Co., Ltd. (hereinafter referred to as "Wanhua Olefin Company"), by a total of 19.086 billion yuan using its own funds and self-raised funds. According to the announcement, in response to the rapid development and continuous expansion of the company's C2 (ethylene) industry, and to enhance the efficiency of asset operation and management, Wanhua Chemical intends to inject assets related to its 1.2 million-ton ethylene integration project (valued at 14.586 billion yuan) and a 4.5 billion yuan debt owed by Wanhua Olefin Company, totaling 19.086 billion yuan, into the subsidiary. Of this capital increase, 1 billion yuan will be allocated to registered capital, while the remaining 18.086 billion yuan will be recorded as capital reserve. Upon completion of the capital increase, the registered capital of Wanhua Olefin Company will rise from 3 billion yuan to 4 billion yuan, with Wanhua Chemical retaining 100% ownership. Through this integration, Wanhua Chemical aims to centralize the operation and management of its C2 industry under a single legal entity, thereby further enhancing the overall competitiveness of this business segment.

It was disclosed that prior to the integration, Wanhua Chemical held a 1.2 million-ton-per-year ethylene plant, which uses ethane and naphtha as feedstocks, along with supporting LDPE facilities. Meanwhile, Wanhua Olefin Company operated another 1.2 million-ton-per-year ethylene plant based on ethane feedstock, along with downstream facilities for PO/SM, HDPE, LLDPE, and PVC. This capital increase will facilitate the deep integration of these two industrial chains.
