The above guarantees to be provided by the Company and its subsidiaries are arranged according to the current business demands. In the event of any possible change, a guarantor can adjust the guarantee amount within the total amount of guarantees in the same category to any of the entities to be guaranteed.

It is estimated that the aggregate external guarantees to be provided by the Group in 2025 will amount to approximately RMB212.3 billion, all of which will be provided to the subsidiaries of the Company. The validity period of the above guarantee scheme commences from the passing of the resolution at the AGM until the conclusion of the annual general meeting of the Company for the year 2025. For basic information of the guaranteed companies, please refer to appendix I of this circular.

LETTER FROM THE BOARD

According to Shanghai Stock Exchange Listing Rules, when providing guarantees to its holding subsidiaries, if a large number of guarantee agreements occur every year and it is difficult to submit each agreement to the Board or the general meeting of the Company, the Company may estimate the total amount of new guarantees for the two types of subsidiaries with a debt-to-asset ratio of more than 70% and a debt-to-asset ratio of less than 70% respectively in the next 12 months, and submit it to the general meeting of the Company for consideration. According to the Shanghai Stock Exchange Listing Rules and the Articles of Association, if the Company intends to provide guarantees to the entities to be guaranteed with debt-to-asset ratio exceeding 70%, such guarantee plan is subject to approval by the Shareholders in a general meeting. The debt-to-asset ratios of some entities to be guaranteed under the Provision of Guarantee for Subsidiaries and Relevant Authorization to the Board exceed 70%. Therefore, it is subject to approval by the Shareholders in a general meeting.

As at the Latest Practicable Date, the above companies included connected subsidiaries of the Company under Chapter 14A of the Hong Kong Stock Exchange Listing Rules, thus these companies constitute connected persons of the Company under Chapter 14A of the Hong Kong Stock Exchange Listing Rules. Therefore, the provision of guarantee from the Group to them constitutes connected transactions of the Company under Chapter 14A of the Hong Kong Stock Exchange Listing Rules (the "Connected Guarantee Transactions").

We refer to the circular of the Company dated 20 September 2023 in relation to the comprehensive products and services agreement entered into between CNPC and the Company. The transactions under the comprehensive products and services agreement and the annual caps therefore have been approved by the Shareholders on 9 November 2023 at the 2023 first extraordinary general meeting of the Company. The Connected Guarantee Transactions will be conducted within the scope of the above agreement. As such, the Connected Guarantee Transactions are not subject to separate announcement and shareholders' approval requirements under Chapter 14A of the Hong Kong Stock Exchange Listing Rules. Pursuant to the Hong Kong Stock Exchange Listing Rules, the guarantees provided by the Group to its subsidiaries under the Provision of Guarantee for Subsidiaries and Relevant Authorization to the Board will not constitute notifiable transactions under Chapter 14 of the Hong Kong Stock Exchange Listing Rules. Therefore, the Company proposed the resolution for Shareholder's approval pursuant to the requirements of the Shanghai Stock Exchange Listing Rules and the Articles of Association.

This resolution was approved by the Board on 28 March 2025. In accordance with the Shanghai Stock Exchange Listing Rules and the Articles of Association, an ordinary resolution will be proposed at the AGM to approve the plan for guarantees to be provided to subsidiaries of the Company with an aggregate amount of RMB212.3 billion in 2025 and authorize the Board to consider and approve the matters relating to the Provision of Guarantee for Subsidiaries and Relevant Authorization to the Board.

GENERAL MANDATE TO ISSUE DEBT FINANCING INSTRUMENTS

In order to satisfy the operational and production needs, further optimize the debt structure, and reduce financing costs of the Company, the Company plans to issue one or certain categories of debt financing instruments through one or more batches.

The Board proposes to the Shareholders to generally and unconditionally authorize the Board at the AGM to determine and deal with the issuance of debt financing instruments denominated in Renminbi or other foreign currency, including but not limited to corporate bonds, short-term financing bonds, super and short-term financing bonds, medium-term notes, enterprise bonds, asset securitization products and asset-backed securities, with the outstanding balance of not more than RMB100 billion (or if issued in foreign currency, equivalent to the middle exchange rate announced by the People's Bank of China on the date of issue) (the "General Mandate to Issue Debt Financing Instruments"). The maturity period of the above debt financing instruments shall be no more than 30 years, either under a single category with fixed term or a portfolio with different maturities. The specific terms and amount of the debt financing instruments with different maturities will be determined by the Board, depending on the relevant requirements and market conditions. The debt financing instruments can be issued to the Shareholders by placing and the specific arrangement (including whether or not to make placing, the proportion of the placing and etc.) shall be determined by the Board based on the market conditions and terms of the issue. The proceeds of any issuance of the debt instruments under the General Mandate to Issue Debt Financing Instruments are expected to be applied to satisfy the operational and production needs, adjust debt structure, increase liquidity of the Company, repay debts of the Company and/or finance the capital expenditure on project investments, and the specific use of proceeds shall be determined by the Board based on the fund needs of the Company.

LETTER FROM THE BOARD

The validity period of the General Mandate to Issue Debt Financing Instruments commences from the passing of the special resolution at the AGM until the conclusion of the annual general meeting of the Company for the year 2025. If the Board and/or its authorized representative has determined to issue debt financing instruments within the period of the General Mandate to Issue Debt Financing Instruments and the Company has obtained approvals, permission or registration from relevant regulatory authorities within the same period, the Company then is allowed to complete the issuance within the validity period confirmed by such approvals, permission or registration.

GENERAL MANDATE FOR SHARE REPURCHASE

A special resolution will be proposed at the AGM, the A Shareholders' Class Meeting and the H Shareholders' Class Meeting to grant to the Board (or any Director authorized by the Board) a mandate to repurchase Shares (including A Shares and/or H Shares) during the Share Repurchase Authorization Period (as defined below), to repurchase not more than 5% of the issued A Shares and/or H Shares as at the date of passing this resolution at the AGM, the A Shareholders' Class Meeting and the H Shareholders' Class Meeting, and to authorize the Board to formulate and implement specific Share repurchase plans, determine whether to cancel the repurchased Shares or hold them as treasury Shares and make appropriate and necessary amendments to the relevant content of the Articles of Association (the "General Mandate for Share Repurchase").

As at the Latest Practicable Date, the Company had 21,098,900,000 H Shares in issue and 161,922,077,818 A Shares in issue. Assuming that such number of Shares remains the same as at the date of passing this special resolution at the AGM, A Shareholders' Class Meeting and H Shareholders' Class Meeting, pursuant to the General Mandate for Share Repurchase, the Board would be allowed to repurchase a maximum of 1,054,945,000 H Shares and 8,096,103,890 A Shares respectively, subject to the passing of the special resolution approving the grant of the General Mandate for Share Repurchase to the Board.

After the General Mandate for Share Repurchase is approved at the AGM, A Shareholders' Class Meeting and H Shareholders' Class Meeting, the Board may formulate and implement specific Share repurchase plans, including but not limited to, the purpose of the proposed Share repurchase, the class, price, number, timing and duration of Shares to be repurchased etc.

The General Mandate for Share Repurchase remains valid during the Share Repurchase Authorization Period. The Share Repurchase Authorization Period refers to period from the passing of the General Mandate for Share Repurchase after approval by the AGM, the A Shareholders' Class Meeting and the H Shareholders' Class Meeting until the expiry of the earlier of: (i) the conclusion of the next annual general meeting of the Company; or (ii) the date on which the General Mandate for Share Repurchase is revoked or amended by a special resolution in the Shareholders' general meeting, the A Shareholders' class meeting and the H Shareholders' class meeting (the "Share Repurchase Authorization Period").

The appendix II to this circular is an explanatory statement which contains details pursuant to Rule 10.06(1)(b) of the Hong Kong Stock Exchange Listing Rules for the purpose of enabling Shareholders to make an informed decision on whether to vote for or against the proposed resolution of the General Mandate for Share Repurchase.
