More importantly, we are witnessing a meaningful expansion in the scale and quality of business opportunities available to the Company. Demand from the thermal and power sectors is currently very strong, and we are actively converting these opportunities into orders. Historically, our near-term order book used to remain in the range of approximately ₹80–100 Crore. Today, we have moved beyond ₹150 Crore, which reflects the increased scale at which Simplex Castings is now operating. Over the years, we have built strong capabilities across manpower, machinery, manufacturing and technical execution. With a larger opportunity pipeline and our strengthened order bidding capabilities, we believe the Company is well positioned to maintain this growth momentum over the next several years. Our focus remains on disciplined execution, profitable growth and building a larger presence across thermal, power, railways and other industrial sectors where our engineering and manufacturing capabilities Mr. Ketan Shah provide us with a strong competitive position.
