Order inflow has been encouraging since the start of the financial year, with over Rs. 226 Cr in orders received so far, and more in the pipeline. While revenue for the quarter was modest, primarily due to temporary delays in customer approvals, these are expected to normalize in the coming quarters. Our strategic investments over the past few years are beginning to translate into meaningful business opportunities and stronger market positioning. We continue to see a healthy pipeline of opportunities and are now receiving larger-value complete system contracts. Our order book currently stands at around ₹ 2,654 Crore (including the orders negotiated and pending receipt), providing healthy revenue visibility. Our foray into counter-drone business and export initiatives continue to gain traction. Backed by the Government's continued focus on indigenous defence manufacturing, we remain confident of achieving our full-year guidance and creating long-term value for our stakeholders”.
