We have reviewed the accompanying statement of Standalone Unaudited Financial Results of Indian Oil Corporation Limited (“the Company”) for the quarter and half year ended 30 September 2025 (“the Statement”) attached herewith, prepared by the Company pursuant to the requirements of Regulation 33 and Regulation 52 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended (the "Listing Regulations"), except for the disclosures regarding (i) Physical Performance (in MMT) stated in the Statement and (ii) Average Gross Refinery Margin stated in note no. 3 to the Statement, both of which have been traced from the representation made by the management. 2. This Statement, which is the responsibility of the Company's Management and approved by the Company's Board of Directors in their meeting held on 27 October 2025, has been prepared in accordance with the recognition and measurement principles laid down in Indian Accounting Standard 34 (“Ind AS 34”) "Interim Financial Reporting" prescribed under Section 133 of the Companies Act, 2013 as amended, read with relevant rules issued thereunder and other accounting principles generally accepted in India. Our responsibility is to express a conclusion on the Statement based on our review. 3. Weconducted our review of the Statement in accordance with the Standard on Review Engagements (SRE) 2410 “Review of Interim Financial Information Performed by the Independent Auditor of the Entity”, issued by the Institute of Chartered Accountants of India. This standard requires that we plan and perform the review to obtain moderate assurance as to whether the Statement is free of material misstatement. A review is limited primarily to inquiries of Company personnel and analytical procedures applied to financial data and thus provides less assurance than an audit. We have not performed an audit and accordingly, we do not express an audit opinion. 4. Based on our review conducted as above, nothing has come to our attention that causes us to believe that the accompanying Statement prepared in accordance with applicable Indian Accounting Standards (Ind AS) and other recognized accounting practices and policies has not disclosed the information required to be disclosed in terms of the Regulation 33 and 52 of the Listing Regulations, including the manner in which it is to be disclosed, or that it contains any material misstatement.
