Form of proxy for the 2025 Annual General Meeting to be held on 3 June 2026
AGM Information Classification · 95% confidence The document is a proxy form for the 2025 Annual General Meeting (AGM) of CNOOC Limited, scheduled for 3 June 2026. It includes instructions for shareholders to appoint proxies to vote on various resolutions, including receiving the audited financial statements, re-electing directors, appointing auditors, and declaring dividends. The content is typical of materials distributed to shareholders to facilitate voting at an AGM. It is not the AGM presentation itself but a proxy form related to the AGM. According to the filing definitions, materials shared during the AGM, including proxy forms, fall under AGM Information (AGM-R). The document length is 6172 characters, which is consistent with a detailed proxy form. Therefore, the appropriate classification is AGM Information (AGM-R).

2025 ANNUAL GENERAL MEETING EXPLANATORY STATEMENT

It includes detailed information about the AGM arrangements, matters to be resolved such as re-election of directors, re-appointment of auditors, declaration of final dividend, and authorisation of remuneration schemes. It references the 2025 annual report and auditor's report but does not contain the full financial statements or audit report itself. The document serves as explanatory materials and notice for the AGM, including proxy forms and resolutions to be voted on. This matches the definition of AGM Information (AGM-R), which covers presentations and materials shared during the AGM. The document is lengthy (15,000 characters) and substantive, not a brief announcement or proxy solicitation only. Therefore, the correct classification is AGM Information (AGM-R).
