PROFIT WARNING

This announcement is made by CITIC Resources Holdings Limited (the "Company", and together with its subsidiaries, the "Group") pursuant to rule 13.09 of the Rules Governing the Listing of Securities on The Stock Exchange of Hong Kong Limited (the "Listing Rules") and the Inside Information Provisions (as defined in the Listing Rules) under Part XIVA of the Securities and Futures Ordinance (Chapter 571 of the Laws of Hong Kong) (the "SFO").

Based on the preliminary review on the unaudited consolidated management accounts of the Group and other information currently available, the board of directors of the Company (the "Board") wishes to inform shareholders of the Company ("Shareholders") and potential investors that the Group is expected to record an unaudited consolidated profit attributable to Shareholders of approximately HK\$170 million to HK\$230 million for the year ending 31 December 2025 (the "Reporting Period"), representing a decrease of approximately 60% to 70% as compared to the year ended 31 December 2024.

The expected decrease in the unaudited consolidated profit attributable to Shareholders for the Reporting Period is mainly attributable to the following factors:

• (i) a significant decrease in average selling price of crude oil sold by the Group for the Reporting Period, as compared to the year ended 31 December 2024;
• (ii) a significant increase in raw material costs, especially the alumina used for the production at the Portland Aluminium Smelter for the Reporting Period, comparing to the year ended 31 December 2024;

{1}------------------------------------------------

• (iii) a significant decrease in the share of profit of an associate resulting from the Group ceasing to have any equity interest in Alumina Limited since 18 July 2024; and
• (iv) a significant decrease in share of profit of a joint venture principally engaged in the development, production and sale of oil and production and sale of road bitumen and clarified oil comparing to the year ended 31 December 2024, resulting from the decrease in crude oil prices for the Reporting Period.

The Company is still in the process of finalising the results of the Group for the Reporting Period. The information contained in this announcement is only a preliminary assessment by the management of the Group based on the unaudited consolidated management accounts of the Group for the Reporting Period and the information currently available to the Group, which are subject to potential adjustment arising from impairment assessment as at year end date and have not been reviewed by the Company's auditors nor were they reviewed by the audit committee of the Company. Shareholders and potential investors are advised to read carefully the annual results announcement of the Group for the Reporting Period, which is expected to be published before the end of March 2025.

The Company will publish further announcements in accordance with the requirements of the Listing Rules as and when necessary.

Shareholders and potential investors are advised to exercise caution when dealing in the shares of the Company.
