TO THE BOARD OF DIRECTORS OF RIGA SUGAR CO. LIMITED 1. We have reviewed the accompanying statement of unaudited standalone financial results (“the Statement”) of RIGA SUGAR CO. LIMITED (“the Company”) for the quarter ended 30th June, 2026 attached herewith, being submitted by the Company pursuant to the requirement of Regulations 33 and 52 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 (“the Regulation”) as amended including relevant circulars issued by the 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 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 there under and other accounting principles generally accepted in India. 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 of material misstatement. A review is limited primarily to inquiries of company personnel and analytical procedures applied to financial data and thus provide 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 the recognition and measurement principles laid down in the applicable Indian Accounting Standards, (“Ind AS”), specified under Section 133 of the Companies Act, 2013 as amended, read with relevant rules issued there under and other accounting principles generally accepted in India, has not disclosed the information required to be disclosed in terms of the Regulation 33 and 52 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended, including the manner in which it is to be disclosed, or that it contains any material misstatement.
