China Aluminum (02600) subsidiary plans to sign an EPC general contracting contract with China Alcoa International for a contract price of about 6.555.57 billion yuan

According to Zhitong Finance App, China Aluminum (02600) announced that on November 6, 2026, after review and approval at the 18th meeting of the 9th board of directors of the Company, the Company's subsidiary, China Aluminum Guinea Co., Ltd. (Chinalco Guinea) (as the contractor) plans to enter into a design, procurement and construction (EPC) general contract (EPC general contract) with China Alcoa International Engineering Co., Ltd. (Chinalco International) (as the contractor). Based on this, Chinalco Guinea plans to hire Chinalco International to provide EPC services for the Guinean alumina project located in the Bofa region of the Republic of Guinea. The EPC general contracting contract is a fixed total price contract. The contract price is approximately RMB 6,555.7 billion. Other than the adjustments agreed in the terms of the contract, the contract price will not be adjusted.

As of the date of this announcement, Chinalco Guinea is a subsidiary of the Company, China Aluminum Group Co., Ltd. (Chinalco Group) is the controlling shareholder of the Company, and Chinalco International is a subsidiary of China Alcoa Group. Therefore, since Chinalco International is a related party of the Company under the “Hong Kong Stock Exchange Limited Securities Listing Rules” (Hong Kong Listing Rules), the proposed transaction under the EPC General Contracting Contract constitutes a connected transaction under Chapter 14A of the Hong Kong Listing Rules. Since the maximum applicable percentage ratio for transactions to be carried out under the EPC general contracting contract may exceed 5% but be less than 25%, this transaction constitutes a potentially discloseable transaction under Chapter 14 of the Hong Kong Listing Rules and a connected transaction under Chapter 14A of the Hong Kong Listing Rules. Therefore, the transaction is subject to the relevant reporting, announcement and independent shareholder approval requirements under Chapter 14 and Chapter 14A of the Hong Kong Listing Rules. Since Mr. Guo Gang, the director of the company, also works for China Alcoa Group, he has already avoided voting on the board resolution on this transaction.

As of the date of this announcement, the parties concerned have not signed an EPC general contract on the above matters. When the EPC general contracting contract is signed, the company will comply with the applicable provisions of the Hong Kong listing rules and promptly fulfill its information disclosure obligations.
