Yours faithfully, For RIR POWER ELECTRONICS LIMITED RAMESH KUMAR NARASINGHBHAN MANAGING DIRECTOR AND C.E.O. Din No. 08257872 Encl. – a/a Independent Auditor’s Review Report on Unaudited Financial Results of RIR Power Electronics Limited for the Quarter and Half year ended September 30, 2026 Pursuant to the Regulation 33 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended Review Report The Board of Directors RIR Power Electronics Limited 1. We have reviewed the accompanying statement of unaudited financial results of RIR Power Electronics Limited (the “Company”) for the quarter ended September 30, 2026 and year to date for the period from April 01, 2026 to September 30, 2026 (“the Statement”), being submitted by the Company pursuant to the requirements of Regulation 33 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended (the "Listing Regulations"). 2. This statement which is the responsibility of the Company’s Management and has been approved by the Board of Directors, has been prepared in accordance with the recognition and measurement principles laid down in Indian Accounting Standard 34 "Interim Financial Reporting" (Ind AS 34), prescribed under Section 133 of the Companies Act, 2013 (“the Act”) as amended, read with relevant rules issued thereunder and other accounting principles generally accepted in India. Our responsibility is to express conclusion on the statements 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. A review of interim financial information consists of making inquiries, primarily of persons 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. Independent Auditor's Review Report on Unaudited Financial Results of RIR Power Electronics Limited for the Quarter and Half year ended September 30, 2026 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 aforesaid Indian Accounting Standards (‘Ind AS’) 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 Listing Regulations, including the manner in which it is to be disclosed, or that it contains any material misstatement.
