Aluminum Corporation of China Limited (Chalco) disclosed that its controlling shareholder, Aluminum Corporation of China (Chinalco), together with concert-party affiliates, has acquired 77.36 million additional shares—comprising 47.60 million A-shares and 29.76 million H-shares—via centralized bidding on the Shanghai and Hong Kong exchanges.

The purchases, executed between 20 July and 11 August 2026, represent approximately 0.45% of Chalco’s total issued share capital and involved a cash outlay of about RMB0.66 billion. Following the transactions, Chinalco and its concert parties hold 5.83 billion shares (5.53 billion A-shares and 0.30 billion H-shares), lifting their combined ownership to roughly 34.01% from 33.56%.

These trades form the initial phase of a previously announced programme under which Chinalco and its affiliates intend to invest no less than RMB1.00 billion and up to RMB2.00 billion to lift their holding by no more than 2% of Chalco’s share capital within a 12-month window ending 19 July 2027. Funding will come from internal resources or dedicated bank loans.

Management highlighted that completion of the purchase plan could be affected by market conditions and other unforeseen factors. No change in Chalco’s controlling shareholder or de facto controller status is expected as a result of the programme.

The company affirmed that all transactions comply with applicable regulations, including the PRC Securities Law, Shanghai Stock Exchange listing rules, and Hong Kong Stock Exchange requirements. Chalco will continue to update the market on further developments through its designated disclosure channels.
