The Board of Directors of Oil and Natural Gas Corporation Limited 1. We have reviewed the accompanying Statement of Unaudited Standalone Financial Results of Oil and Natural Gas Corporation Limited ("the Company") for the quarter and half year ended September 30, 2026 (hereinafter referred to as “the Statement"), being submitted by the Company pursuant to the requirements of Regulation 33 and 52 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended (“the Listing Regulations”) including relevant circulars issued by SEBI from time to time. 2. This Statement, which is the responsibility of the Company's Management and approved by the Company’s Board of Directors, has been prepared in accordance with the recognition and measurement principles laid down in the Indian Accounting Standard 34 "Interim Financial Reporting" ("Ind AS 34"), 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 and in compliance with Regulations 33 and 52of the Listing Regulations. Our responsibility is to express a conclusion on the Statement based on our review. 3. We conducted 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 from material misstatement. A review of interim financial information consists of making inquiries, primarily of the Company's personnel responsible for financial and accounting matters and applying analytical and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Standards on Auditing and consequently does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. 4. Based on our review conducted as stated in paragraph 3 above, nothing has come to our attention that causes us to believe that the accompanying Statement, prepared in accordance with applicable Indian Accounting Standards specified under Section 133 of the Companies Act, 2013 as amended, read with relevant rules issued thereunder and other accounting principles generally accepted in India, has not disclosed the information required to be disclosed in terms of the Regulations 33 and 52of the Listing Regulations, including the manner in which it is to be disclosed, or that it contains any material misstatement. 5. Emphasis of Matters We draw attention to the following matters in the Notes to the Statement: - i. Note no. 1 to the accompanying Statement, reviewed and approved directly by the Board of Directors of the Company on November 05, 2026, as the Audit Committee could not be reconstituted by that date due to non-availability of Independent Directors on the Board of the Company and hence, the Audit Committee meeting could not be held on that date. ii. Note No. 3 to the accompanying Statement, in respect of pending finality of Arbitration Tribunal Award on various issues related to Production Sharing Contract with respect to Panna Mukta and Mid and South Tapti contract areas (PMT JV), demand of USD 1,624.05 million equivalent to Rs. 15,583 Crore as on September 30, 2026 (Rs. 15,225 Crore up to March 31, 2026) on the Company, T R Chadha & Co LLP P K F Sridhar & Santhanam LLP Suri & Co.
