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 (ICAI). 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 specified under section 143(10) of the Companies Act, 2013 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 the recognition and measurement principles laid dewn in the aforesaid Indian Accounting Standard and other accounting principles generally accepted in India, has not disclosed the information required to be disclosed in terms of Regulation 33 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. 5.

Company’s management has converted the financial results of the branch located outside India for accounting principles generally accepted in their respective covntries to accounting generally accepted in PGS & Associates Chartered Accountants India. We have reviewed these changes made by the Company’s management. Our conclusion is so far as it relates to the balances and affairs of such branch located outside India is based on the report of management certified accounts and conversion adjustments prepared by the management of the Company and reviewed by us. The accompanying Statement of quarterly standalone financial results includes the unaudited interim financial results in respect of Diffusion ESOP Trust whose interim financial results and other financial information reflect total revenues of Rs. Nil, total net profit after tax of Rs Nil and total comprehensive income of Rs. Nil for the quarter ended June 30, 2026 as considered in the Statement which have been reviewed by the auditor of Diffusion ESOP Trust. The report of such auditor on interim financial results/financial information oft his trust has 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 this trust, is based solely on the report of such other auditor. The Standalone Financial Results for the quarter ended 31st March, 2026 is the balancing figures between audited standalone figures year ended 31st March, 2026 and unaudited standalone figures in respect of the nine-month period ended 31st December, 2025.
