Aluminum Corporation of China Limited (Chalco) disclosed that its controlling shareholder, Aluminum Corporation of China (Chinalco), together with concert-party affiliates, plans to raise its combined holdings of both A-shares and H-shares in Chalco over the next twelve months.

The proposed purchase will be executed through the trading platforms of the Shanghai and Hong Kong stock exchanges, with an intended outlay of no less than RMB1.00 billion and no more than RMB2.00 billion. The volume to be acquired will not exceed 2% of Chalco’s total share capital. Execution timing will be guided by prevailing market conditions.

As of 20 July 2026, Chinalco directly owned 5,235,235,416 shares in Chalco (including 5,189,333,416 A-shares and 45,902,000 H-shares), equal to 30.52% of total share capital. Through subsidiaries—Baotou Aluminium (Group), Chinalco Asset Operation and Management, and Aluminum Corporation of China Overseas Holdings—Chinalco held an additional 521,107,132 shares (292,739,132 A-shares and 228,368,000 H-shares). Combined direct and indirect stakes amount to 5,756,342,548 shares, or 33.55% of Chalco’s issued share capital.

Funding for the additional purchases will come from Chinalco’s internal resources or self-raised funds. Chinalco and its concert parties have committed not to reduce their holdings during the purchase window or within the statutory lock-up period thereafter.

The company cautioned that completion of the planned share increase may be affected by market conditions and other unforeseen factors. Regulatory compliance has been affirmed, and the transaction will not alter Chalco’s controlling shareholder or de facto controller. Chalco will provide timely disclosures on material developments via the Shanghai Stock Exchange website and designated financial media outlets.
