Commenting on the results, Mr. Krishan Lalit Bansal, Chairman, DEE Development Engineers Limited said :

“We are pleased to announce a very strong performance for the quarter and half year ended September 30, 2025, underscored by robust revenue growth and consistent operational execution.

Operating Income for the quarter stood at ₹27,000 Lakhs, reflecting a strong year-on-year growth of 39.2% and a sequential increase of 20.7%. Operating EBITDA for the quarter rose 47.9% year-on-year to ₹4,406 Lakhs, with margins expanding by 96 bps to 16.3%. Q2 FY26 PAT stood at ₹1,786 Lakhs, with a margin of 6.5%. The year-on-year fall in PAT was primarily attributable to an exceptionally high other income of ₹1,598 Lakhs in Q2 FY25, arising from non-recurring items. Adjusting for this, the normalized Operating PBT for Q2 FY25 would have been ₹1,016 as against ₹1,717 Lakhs in Q2FY26, reflecting a growth of 69% in the underlying operational profitability.

For H1 FY26, Revenue from Operations grew 30.3% year-on-year to ₹49,376 Lakhs. Operating EBITDA increased 46.4% to ₹7,993 Lakhs, with margins expanding by 179 bps to 16.2%. PAT for H1 FY26 stood at ₹3,106 Lakhs, up 22.1% year-on-year.

The Company continues to witness traction in the power sector, with new orders received of ₹170 Crores from leading thermal power players. Supported by healthy demand from the oil and gas segment and an order book of ₹1,308 Crores as on 30th September 2025, the Company remains well positioned for sustained growth.

On the operational front, the Company commissioned its production capacity of 30,000 MT at its Anjar facility on 8th September 2025, marking a key milestone in its expansion journey. Commissioning of 7,000 MT Seamless Pipe Plant is on track for commissioning by the end of Q3 FY26 and is on course to commence commercial production by January 2026, further strengthening backward integration and cost competitiveness.

Looking ahead, the Company remains focused on execution excellence, expanding capacities, and capitalizing on emerging opportunities to drive sustainable growth and long-term value for all stakeholders.”
