We have reviewed the accompanying statement of unaudited standalone financial results of DEE Development Engineers Limited (the “Company”) for the quarter ended June 30, 2026 (the “Statement”) attached herewith, being submitted by the Company pursuant to the requirements of Regulation 33 of the SEBI (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 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 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 theStandard 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. 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 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.

Emphasis of Matter We draw attention to Note 6 to the standalone financial results, which describes the uncertainty relating to the appeal filed by Punjab State Power Corporation Limited (PSPCL) before the Appellate Tribunal for Electricity (APTEL), New Delhi, and the Civil Writ Petition filed by the Company before the Hon’ble High Court of Punjab and Haryana, in respect of the dispute between the Company and PSPCL regarding the retrospective downward revision of tariff by PSPCL effective January 1, 2024. As the matters are sub-judice, no adjustments have been made in the accompanying standalone financial results. Our conclusion is not modified in respect of this matter. For S.R. Batliboi & Co.
