Name of the listed entity / material subsidiary: Transgene Biotek Limited 2. Details of the Statutory Auditor: a. Name: M/s Eswara Rao & Co., Chartered Accountants (FRN: 000816S) b. Address: Flat No. 403, Syamala Homes, 4/1, Syamala Nagar, Pattabhipuram, Guntur – 522006 c. Phone number: 9666280187 d. Email: admin@eswararaoandco.com 3.

Date on which the term of the Statutory Auditor was scheduled to expire: Until the conclusion of the next Annual General Meeting of the Company, subject to the approval of the members (appointment by the Board of Directors under Section 139(8)(i) of the Companies Act, 2013 to fill a casual vacancy) c. Prior to resignation, the latest audit report / limited review report submitted by the auditor and date of its submission: Not applicable. No audit report or limited review report was issued by us prior to our resignation. 4. Detailed reasons for resignation: Subsequent to our appointment on 10 October 2026, we held a preliminary meeting with the management of the Company, and the management had started sharing the information required for the limited review of the financial results for the quarter ended 30 September 2026. However, before the engagement work could commence, a medical emergency in the family required both partners responsible for the engagement to travel to Guntur at short notice. The limited review report for the quarter ended 30 September 2026 was due by 14 November 2026. As first-year auditors of the Company, we would have needed adequate time to understand the Company’s business, accounting systems and internal controls before issuing the report. In the circumstances, we would not have been able to complete the limited review with the required quality within the prescribed timeline, and none of the other partners of the firm had the capacity to take up the engagement at such short notice. As we would not have been able to do justice to the engagement, we resigned as Statutory Auditors of the Company with effect from 28 October 2026. 5. In case of any concerns, efforts made by the auditor prior to resignation (including approaching the Audit Committee / Board of Directors along with the date of communication made to the Audit Committee / Board of Directors): Nil. 6.

Whether the inability to obtain sufficient appropriate audit evidence was due to a management-imposed limitation or circumstances beyond the control of the management: Not applicable. b. Whether the lack of information would have a significant impact on the financial statements / results: Not applicable. c. Whether the auditor has performed alternative procedures to obtain appropriate evidence for the purposes of audit / limited review as laid down in SA 705 (Revised): Not applicable. d.
