We have reviewed the accompanying statement of unaudited financial results ('the Statement') of CSB Bank Limited ('the Bank') for the quarter ended 30 June 2026, being submitted by the Bank pursuant to the requirements of Regulation 33 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015 (as amended) ('Listing Regulations'), except for the disclosures relating to Pillar 3 disclosure as at 30 June 2026, including leverage ratio, liquidity coverage ratio and net stable funding ratio under Basel Ill Capital Regulations as have been disclosed on the Bank's website and in respect of which a link has been provided in the Statement and have not been reviewed by us. 2. The Statement, which is the responsibility of the Bank's management and approved by the Bank's Board of Directors, has been prepared in accordance with the recognition and measurement principles laid down in Accounting Standard 25, Interim Financial Reporting ('AS 25'), prescribed under section 133 of the Companies Act, 2013 ('the Act'), the relevant provisions of the Banking Regulation Act, 1949, the circulars, guidelines and directions issued by the Reserve Bank of India ('the RBI') from time to time, applicable to banks ('the RBI guidelines'), and other accounting principles generally accepted in India, and is in compliance with the presentation and disclosure requirements of Regulation 33 of the Listing 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 the 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.

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 AS 25 prescribed under section 133 of the Act, the RB I guidelines, and other accounting principles generally accepted in India, has not disclosed the information required to be disclosed in accordance with the requirements of Regulation 33 of the Listing Regulations, including the manner in which it is to be disclosed, or that it contains any material misstatement, or that it has not been prepared in accordance with the relevant prudential norms issued by the RBI in respect of income recognition, asset classification, provisioning and other related matters, except for the disclosures relating to Pillar 3 disclosure as at 30 June 2026, including leverage ratio, liquidity coverage ratio and net stable funding ratio under Basel Ill Capital Regulations as have been disclosed on the Bank's website and in respect of which a link has been provided in the Statement and have not been reviewed by us.
