We sincerely appreciate your continued trust, support and participation.

Before Venkat takes you through the financial performance, I'd like to share a few key business updates and our outlook for the coming quarters. The quarter marks another important step in our long-term growth strategy. As our strategic investments over the past several years are beginning to translate into tangible business, business opportunity and a stronger market position. We continue to witness healthy customer engagement across multiple defense programs with increasing opportunities for larger value and complete contracts. We secured orders across avionics, radars, electronic warfare and automotive test equipment programs from various customers, including Ministry of Defense, DRDO and BrahMos, reflecting the growing confidence in our technology capabilities and execution track record. We also continue to pursue several large opportunities and are currently at various stages of discussion evaluation. A key milestone for us has been the successful transition of several products from the development stage to complete system solutions. This significantly expands our addressable market and enables us to participate in larger and higher-value programs. With differentiated capabilities, we're trying to convert them into single vendor opportunities. We're also leveraging our existing technology platforms and reusable building blocks to develop new products faster and more cost effectively, improving both scalability and speed to market. Our order book stands at INR2,654 crores, including orders negotiated, providing a healthy revenue visibility over the coming years. Page 2 of 23 Data Patterns (India) Limited July 31, 2026 Our international order book currently stands at INR39 crores, and we continue to actively engage with customers across global markets to expand our export footprint. We also remain confident of securing around INR2,000 crores of fresh order inflows during FY '27 over and above the orders already received and negotiated. Policy environment also remains highly favorable. The government's continued focus on higher indigenous content and defense procurement is creating significant opportunities across the ecosystem, including the armed forces, defense PSUs and private sector companies. With a strong in-house design capabilities and proven execution track record, we believe Data Patterns is well positioned to benefit from this structural opportunity. Another encouraging development during the quarter was the initial traction in our drone and counter drone business, where we have started receiving orders. We believe that this business will become an important growth driver as demand for indigenous unmanned and counter UAVs solutions continue to increase. Coming to the quarter, our revenue trajectory continues to remain on track. As indicated earlier, we continue to invest in strengthening our engineering talent and future capabilities, resulting in higher employee cost base, is expected to remain elevated over the coming quarters. In addition, changes in the product is also impacted margins during the quarter. There are conscious investments that strengthen our long-term competitive position and prepare us for larger opportunities ahead. Looking ahead, the outlook of the Indian defense sector remains highly encouraging, supported by a robust order pipeline, expanding product portfolio, increasing export opportunities and favorable policy content, we remain confident of achieving our full year guidance, growth guidance of 20% to 25% revenue growth while maintaining EBITDA margins in the 35% to 40% range. We remain committed to investing in the technology, innovation and indigenous capability development while creating sustainable long-term value to all our customers. With that now, I hand over the floor to our CFO, Venkat, to take through the financial performance in greater detail.
