Chairman's Message “The previous quarter marked a new chapter for John Cockerill, with the consolidation of our Chinese, German, and Belgian entities under JCIL, creating a more integrated, agile, and cohesive organization. We delivered another quarter of strong year-on-year growth in Q2 CY26. Standalone Revenue grew 82%, while Consolidated Revenue increased 18% year-on-year. While revenue in Q2 CY26 moderated sequentially, primarily due to project-related factors as we prepared to ramp up execution of new project orders, underlying demand remained strong. This was reflected in healthy customer enquiries and a strong pace of order wins. On a YTD basis, Standalone Revenue grew 120%, while Consolidated Revenue increased 36% in H1 CY26, highlighting the continued strength of the business. We are witnessing consistent and strong demand from customers, driven not only by capacity expansion but increasingly by investments in advanced processing technologies, electrical steel, downstream quality enhancement and plant modernization. At the end of the quarter, our consolidated order backlog stood at ₹45,989 million. This provides strong revenue visibility and reinforces our confidence in the growth trajectory of the business over the coming years. We have started executing several new orders secured recently, and these projects are still in their early stages. At this stage, we incur a number of initial project costs, without any margin contribution. This will build progressively as Mr. Francois-David execution advances. As these projects progress into more advanced stages of execution, we expect revenue and MARTINO margin contribution to increase, supporting stronger profitability over the medium term. Chairman This is already reflected in our YTD performance. Standalone EBITDA for H1 CY26 has increased more than five-fold compared to H1 CY25, while the Consolidated EBITDA loss has narrowed considerably from ₹27 crores in H1 CY25 to ₹19 crores in H1 CY26. This demonstrates that quarterly profitability can vary depending on the stage of project execution and revenue mix, while the underlying improvement becomes more visible on a Year-to-Date basis. In conclusion, I would like to say that the direction is clear, and the order backlog is stronger. As we enter the next phase of our growth journey, we are doing so from a significantly stronger foundation, supported by a robust order book, growing execution team, and a more integrated global operating platform. With India continuing to emerge as one of the most attractive steel investment markets globally, we believe the medium-to-long-term opportunity for JCIL remains substantial.” Financial & Operational Performance Q2 & H1 CY26 ENGINEERING | DESIGN | MANUFACTURING | ERECTION & COMMISSIONING | VALUE SERVICES Standalone Financial Highlights — Q2 & H1 CY26 Business on strong footing with robust Order Book providing strong visibility for the coming years Revenue grew strongly by 82% and Revenue Material Margin 120% Y-o-Y in Q2 and H1 CY26 Q2 H1 Q2 H1 respectively.
