We have reviewed the accompanying Statement of Standalone Unaudited Financial Results of Diamines and Chemicals Limited ("the Company"), for the quarter and half year ended September 30, 2026 ("the Statement"), being submitted by the Company pursuant to the requirement of Regulation 33 of the Securities and Exchange Board of India (Listing Obligations and Disclosure Requirements) Regulations, 2015, as amended (the "Listing Regulations"). 2. The Company's management is responsible for the preparation of the Statement in accordan~e with the recognition and measurement principles laid down in Indian Accounting Standard ("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 of the Listing Regulations. The Statement has been approved by the 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 ("ICAI''). 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 the company's personnel responsible for financial and accounting matters and applying analytical procedures and other review procedures. A review is substantially less in scope than an audit conducted in accordance with Standard 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 the significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion. 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 Ind AS and other accounting principles generally accepted in India has not disclosed the information required to be disclosed in terms of Regulation 33 of the Listing Regulations, including the manner in which it is to be disclosed, or that it contains any material misstatement.
