Operating revenue grew 35% YoY in Q2 FY27 and 33% YoY in H1 FY27. Annual Recurring Revenue (ARR) in the RegTech segment rose 42% year to date, driven by strong traction in IRIS CARBON, the enterprise SaaS offering from IRIS. EBITDA for Q2 FY27 stood at INR 4.1 crore, compared with INR 2.7 crore in Q2 FY26 and INR 0.8 crore in Q1 FY27. Commenting on the Q2 FY27 and H1 FY27 results, K. Balachandran, Co-Founder and CEO, IRIS RegTech Solutions Limited, said: "We are pleased with our first half performance, led by strong growth in IRIS CARBON, our flagship SaaS platform, on the back of new customer wins in disclosure management. IRIS CARBON ARR also benefited from a large engagement with a global energy major that commenced towards the end of the second quarter. IRIS iDeal, our bank regulatory reporting solution, saw growing traction for its end-to-end regulatory reporting offering, further deepening our engagement with banks and financial institutions. Our SupTech business delivered solid growth in the first half while sustaining healthy operating margins. While developments in the Middle East and the resulting global economic uncertainty slowed new order intake in this segment, we offset this by expanding our engagements with existing regulator clients. Overall, we remain focused on scaling our SaaS-led offerings, deepening our presence across key markets and building on the opportunities we see across both RegTech and SupTech." Vineet Kandoi, CFO, IRIS RegTech Solutions Limited, added: "While our first half performance has been encouraging, in order to sustain momentum, we plan to further invest in sales and marketing and in product innovation, including deepening our AI capabilities. We believe these investments will position us well for continued growth over the coming years." Key performance highlights • RegTech: The fastest-growing segment, with H1 FY27 revenue up 50% year on year. Growth was led primarily by continued expansion of the IRIS CARBON disclosure management platform, which now serves more than 50 customers, primarily in Europe and the Americas. IRIS iDeal went live with its first end-to-end regulatory reporting solution at one of India's small finance banks, advancing the company's strategy to deepen its presence among financial institutions. • SupTech: H1 FY27 revenue grew 25% year on year at an EBITDA margin of 29%, led by regulatory digital reporting implementations in Africa and the Middle East. The segment also extended its footprint to the Philippines.
