Nature of Disclosure: Regulatory filing under Regulation 30 of SEBI Listing Requirements regarding ongoing GST litigation involving a wholly-owned subsidiary.

Background: Abacus Real Estate Private Limited, a wholly-owned subsidiary of Kalpataru Limited, had previously filed an appeal with the Principal Commissioner (Appeals-I), Hyderabad GST Commissionerate. This appeal was against an Order dated May 27, 2024, issued by the Adjudicating Authority, GST Department, Hyderabad GST Commissionerate. The original order demanded transitional credit of ₹1,35,66,011 along with applicable interest and an equivalent penalty amount (₹1,35,66,011), covering the period from July 1, 2017, to March 31, 2018.

Recent Development: The Appellate Authority allowed Abacus's appeal through its Order-in-Appeal dated January 29, 2026. However, the GST Authority has now filed a subsequent appeal before the GST Appellate Tribunal challenging this favorable Order-in-Appeal. The appeal seeks to reinstate the original tax demand of ₹1,35,66,011 plus applicable interest and an equivalent penalty.

Company's Position: Abacus intends to defend against this appeal and remains hopeful of a favorable outcome. The company explicitly states that this filing of appeal before the GST Appellate Tribunal "does not have any material financial impact on the operations of the Company."

Timeline: Kalpataru Limited received information about this appeal filing from Abacus on September 16, 2026, at 12:47 p.m. The disclosure was made to the exchanges on September 17, 2026.
