We have reviewed the accompanying Statement of Unaudited Consolidated Financial Results of The Tata Power Company Limited (the "Holding Company") and its subsidiaries (the Holding Company and its subsidiaries together referred to as "the Group"), its associates and joint ventures for the quarter ended September 30, 2026 and year to date from April 01, 2026 to September 30, 2026 (the "Statement") attached herewith, being submitted by the Holding 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"). 2. The Holding Company's Management is responsible for the preparation of the Statement 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 and in compliance with Regulation 33 and 52 of the Listing Regulations. The Statement has been approved by the Holding Company's Board of Directors. 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 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. We also performed procedures in accordance with the Master Circular issued by the Securities and Exchange Board of India under Regulation 33(8) of the Listing Regulations, to the extent applicable. 4. The Statement includes the results of the following entities as per Annexure 1 5. Based on our review conducted and procedures performed as stated in paragraph 3 above and based on the consideration of the review/audit reports of other auditors referred to in paragraph 7 and 8 below, nothing has come to our attention that causes us to believe that the accompanying Statement, prepared in accordance with 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.

We draw attention to Note 3 of the consolidated financial results wherein the Holding Company had received an unfavourable arbitration award seeking payment of USO 490.32 million and related costs and interest during the year ended March 31, 2026, for which appeals were filed by the Holding Company. During the quarter ended September 30, 2026, the Singapore International Commercial Court ("SICC") dismissed the Holding Company's appeal to set aside the award and subsequently an enforcement order has been issued by the SICC pursuant to which on 6th November, 2026, notices were served intimating attachment of the Holding Company's shareholding in certain Singapore subsidiaries by the Court-appointed Sheriff. Based on the advice of legal counsels, the Holding Company has filed notices of appeal before the Singapore Court of Appeal ('Apex Court') and is required to file its written submissions by November 23, 2026. Further, the Holding Company is in the process of filing objections to the Enforcement Order and proceedings and seeking a deferment of sale of shares from the Sheriff, considering the ongoing appeal before the Apex Court. Pending the final outcome of the Apex Court and Enforcement proceedings as mentioned in the aforesaid note, no adjustments have been made in the consolidated financial results for the quarter ended September 30, 2026 and the year to date results for the period from April 01. 2026 to September 30, 2026. Our opinion is not modified in respect of this matter. 7.
