We have reviewed the accompanying Statement of consolidated unaudited financial results of IRB Infrastructure Developers Limited (hereinafter referred to as 'the Holding Company') and and its subsidiaries (the Holding Company and its subsidiaries together referred to as the 'Group') for the quarter ended June 30, 2026 ('the Statement') attached herewith, being submitted by the Holding Company pursuant to the requirements of Regulation 33 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended ('the Regulations'). 2. This Statement, which is the responsibility of the Holding Company's Management and approved by the Holding Company's Board of Directors, has been prepared in accordance with the recognition and measurement principles laid down in Indian Accounting Standard 34 'Interim Financial Reporting' prescribed under Section 133 of the Companies Act, 2013 ('the Act') read with relevant rules issued thereunder ('Ind AS 34') and other recognised accounting principles generally accepted in India and is in compliance with the 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. 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 specified under section 143(10) of the Act 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 circular issued by the Securities and Exchange Board of India under Regulation 33 (8) of the Regulations, to the extent applicable. 4. This Statement includes the results of the Holding Company and the entities stated in 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 reports of the other auditors referred to in paragraph 6 below, 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 Ind AS 34 and other recognised accounting principles generally accepted in India has not disclosed the information required to be disclosed in terms of the Regulations, including the manner in which it is to be disclosed, or that it contains any material misstatement.

These interim financial information have been reviewed by other auditors whose reports have been furnished to us by the Management and our conclusion on the Statement, in so far as it relates to the amounts and disclosures included in respect of these subsidiaries, is based solely on the report of the other auditors and the procedures performed by us as stated in paragraph 3 above.
