  3. Review of operating results

    In the first quarter of 2026, China's economy maintained stable growth, registering a GDP growth of 5.0% year-on-year. Affected by the geopolitical conflict in the Middle East, international crude oil prices increased significantly, with the spot price of Platts Brent averaged USD80.6 per barrel, up by 6.5% year-on-year. Based on the Company's statistics, domestic demand for natural gas increased by 3.1% year-on-year. Mainly affected by alternative energy, domestic consumption of refined oil products declined by 2.3% year-on-year. The domestic demand for chemicals went up steadily, with the consumption of ethylene equivalent and the apparent consumption of PX increased by 1.0% and 6.5% year-on-year respectively, the apparent consumption of synthetic resin and synthetic fiber rose by 0.8% and 4.6% year-on-year respectively, and the apparent consumption of synthetic rubber fell by 0.4% year-on-year.

    In the first quarter of 2026, the Company strengthened market research, particularly in response to the impact of the Middle East geopolitical conflicts since March, dynamically adjusted production and operation arrangements to maintain steady operation of the whole industrial chain.

In terms of development, we accelerated the construction of key projects such as Tahe, West Junggar, and offshore fields, strengthened the development of shale oil, and proceeded with the fine development in mature oil and gas fields. At the same time, we further boosted the synergy of production, supply, storage and sales to enhance the profitability of the natural gas business. In the

    first quarter, the Company's production of oil and gas was 131.49 million barrels of oil equivalent, up by 0.4% year-on-year, among which, the crude oil production totaled 69.80 million barrels and natural gas production reached 370.0 billion cubic feet.

    3. Differences between consolidated financial statements prepared in accordance with the accounting policies complying with CASs and IFRS Accounting Standards (Unaudited)

      Other than the differences in the classifications of certain financial statements captions and the accounting for the items described below, there are no material differences between the Group's consolidated financial statements prepared in accordance with the accounting policies complying with CASs and IFRS Accounting Standards. The reconciliation presented below is included as supplemental information, is not required as part of the basic financial statements and does not include differences related to classification, presentation or disclosures. Such information has not been subject to independent audit or review. The major differences are:

      1. Government grants

        Under CASs, grants from the government are credited to capital reserve if required by relevant governmental regulations. Under IFRS Accounting Standards, government grants relating to the purchase of fixed assets are recognised as deferred income and are transferred to the income statement over the useful life of these assets.

      2. Safety production fund

        Under CASs, safety production fund should be recognised in profit or loss with a corresponding increase in reserve according to PRC regulations. Such reserve is reduced for expenses incurred for safety production purposes or, when safety production related fixed assets are purchased, is reduced by the purchased cost with a corresponding increase in the accumulated depreciation. Such fixed assets are not depreciated thereafter. Under IFRS Accounting Standards, payments are expensed as incurred, or capitalised as fixed assets and depreciated according to applicable depreciation methods.

      3. Capitalisation of exchange difference of specific loans

      Under CASs, exchange difference arising on translation of specific loans and related interest denominated in a foreign currency should be capitalised as part of the cost of qualifying assets. Under IFRS Accounting Standards, such exchange difference is recognised in income statement unless the exchange difference represents an adjustment to interest.

      Effects of major differences between the net profit under CASs and the profit for the period under IFRS Accounting Standards are analysed as follows:

    4. Changes in accounting estimate

(i) Adjustment of the depreciation period for chemical units and natural gas pipelines

On 28 April 2026, the Company's board of directors approved an adjustment of the depreciation period for natural gas pipelines and the new chemical units added since the 14th Five-Year Plan. This accounting estimate change resulted in a reduction of approximately RMB300 million in depreciation and amortisation for the three-month period ended 31 March 2026 of the Company.
