18.57%−81.43 ppBusiness relationship
Read full ownership purposeThe company will maintain certain cooperation in areas that lead to improved competitiveness for both parties, such as joint research and development in green transition and carbon neutrality, while ensuring the independence of the issuer, Crasus Chemical Inc. (hereinafter referred to as “Crasus Chemical”). Effective 1 Oct 2026, the execution of the partial spin-off of Crasus Chemical, which was a wholly-owned subsidiary of the company engaged in petrochemical business, as common stock of Crasus Chemical (hereinafter referred to as “Crasus Chemical Stock”), was completed, and the effect of the in-kind dividend arose. As a result of the execution of this spin-off, the ownership ratio of Crasus Chemical Stock held by the company became 18.57%, and since Crasus Chemical is no longer a consolidated subsidiary of the company and the company is not expected to have significant influence over Crasus Chemical, it is no longer subject to the equity method.
