Aluminum Corporation of China Limited (CHALCO) announced a delay in issuing its shareholder circular related to the planned investment and construction of the Guinea Alumina Project, as well as the option for additional equity participation by the Guinean party.

Originally scheduled for release on or before 10 August 2026, the circular is now expected to be dispatched no later than 30 November 2026. The company cited the need for additional time to prepare and finalize the required information as the reason for the postponement.

The change does not alter the underlying terms of the major transaction; it only affects the timeline for providing detailed information to shareholders.

The announcement was authorized by the Board and signed by Joint Company Secretary Zhu Dan on 7 August 2026 in Beijing, the PRC. At the announcement date, the Board comprised three Executive Directors—He Wenjian, Zhang Ruizhong, and Mao Shiqing—two Non-executive Directors—Guo Gang and Jiang Hao—and three Independent Non-executive Directors—Yu Jinsong, Chan Yuen Sau Kelly, and Li Xiaobin.
