Thank you for logging in for this 1Q FY27 earnings call of IndiGrid Infrastructure Trust. From the management, we have Mr. Harsh Shah, Managing Director; and then we have Ms. Meghana Pandit, Chief Financial Officer, followed by Mr. Sanil Namboodiripad, Chief Operating Officer. Without further ado, I would hand over the call to the management for their opening remarks, post which we'll take the Q&A. Over to you, sir. Harsh Shah: Hi. Good evening, everyone, and a very warm welcome to our quarter 1 FY27 results call. As we have done before, I'm going to take you through the presentation in the first part, then my colleague, Meghana, and Sanil will take certain sections of the presentation, and we'll address the question answer subsequently. I'm on Slide number 3. Our vision is to become the most admired yield vehicle in Asia. We focus on a business model with long-term contracts, low operating risk, and stable cash flows. We strive to do value-accretive growth by doing DPU-accretive acquisitions year-on-year and creating a pipeline for the future. We focus on delivering a quarterly predictable distribution to our unitholders. And while doing all this, we focus on an optimal cap structure. On Slide 4 is our portfolio as of date, with assets under management of approximately INR34,000 crores. Our presence is across 20 states and 2 union territories across 94 different revenue-generating elements, which include 59 transmission lines spanning 10,000-plus circuit kilometers, 20 substations with a capacity of 34,335 MVA, 1.5 gigawatt peak of solar capacity, and 2.5 giga-watt hour of BESS projects at different stages of construction. Many of our projects are build, own, and operate. Therefore, there is a physical asset that belongs to us that's captured in steel and aluminum. But beyond that, our average residual contract period for transmission is approximately 26 years for solar, about 18.8 years, and for battery storage, 11.5 years. On Slide number 6, the highlights for this quarter. This quarter, EnerGrid, where we have partnered with 2 financial investors to develop more projects on transmission and BESS, we received 2 letters of intent, one for the Shongtong transmission scheme awarded through the TBCB mechanism. It's an ISTS project comprising 450 circuit kilometers of lines and 400 to 220 kV 630 MVA substations to be developed. This is in the state of Himachal. Page 2 of 11 IndiGrid Infrastructure Trust August 13, 2026 The second project is also in the state of Himachal, where the transmission system for evacuation of power from Sunni Dam and Luhri Stage-1 is awarded through TBCB to us, which comprises about 104 circuit kilometers of transmission lines and about 1,000 MVA of substation capacity. Both projects put together have approximately cumulative capex of INR5,800 crores. This is something which IndiGrid will acquire as and when the projects are revenue-generating and operational, and add approximately a little over INR6,000 crores of AUM to IndiGrid subsequently. In terms of the quarterly financial performance, our operational revenue stood at INR930 crores, up approximately 19% year-on-year. The growth is primarily driven by the addition of new projects into the portfolio throughout the year. The revenue growth translated into operational EBITDA growing approximately 23% year-on-year and stood at INR860 crores. Our EBITDA margin stood at 89.1%. Net debt to AUM ratio remain very low. We are at 58.5% net debt to AUM, which translates into roughly another NR10,000 crores, INR12,000 crores of assets that we can acquire without necessarily raising more capital. Q1'27 collections are at 95% on transmission and 100% for solar. Transmission collections are relatively lower. However, this is a usual trend that we have seen across the last 10 years, where quarter 1 collections are typically lower and then collections pick up in quarter 3 and quarter 4 subsequently. So we see the same trend panning out this year as well. In terms of distribution, as you know, we increased the distribution to INR16.48 a unit last quarter for the full year this year. In line with that, we are distributing INR4.12 a unit for quarter 1, '27. Our weighted average quarterly transmission availability remains at 99.64%, Solar CUF at 26.5%, and the BESS round-trip efficiency of the portfolio is at 88.4%. We believe that our strategy is something that allows us to continue to deliver superior total returns and sustainable DPUs and stable operations. On the next slide, I'll take you through the industry update. Our demand as a country and capacity trend, we see are on a continuously increasing trend. As you can see in quarter 1 FY26 and quarter 1 FY27, there is a 12.5% growth of peak capacity, which is a significant growth by any standards on such a large portfolio. And we do feel that this is still lower than what India could achieve. And therefore, over the next 10 years, we are certain that these capacities and the growth are going to continue to remain in the energy sector. Some of the signs of that are evident in the developments in the transmission and renewable sector, increasing the earlier 500-gigawatt nonfossil capacity target to 900 gigawatts in t [Showing first 8,000 characters — download PDF for full document]
