Page 1 of 26 Yash Highvoltage Limited October 21, 2026 I now hand the conference over to Mr. Keyur Shah, Chairman and Managing Director from Yash Highvoltage Limited. Thank you and over to you, sir. Keyur Shah: Thank you so much, madam. Good evening, everyone, and a very warm welcome to Yash Highvoltage's Earnings Conference Call for the first half ended September '26. I am joined today by Mr. Darshan Thakkar, our Executive Director, Finance; Mr. Nirav Patel, Executive Director, Global Business; and Mr. Mitanshu Shah, our Strategic Advisor. Our financial results, investor presentation, and press release have been uploaded to the stock exchange and our website. I trust you have had an opportunity to review these documents. H1 '27 marked a period of operational and strategic progress for the company with key developments across international expansion, product capabilities, greenfield facility operations, and internal systems strengthening our foundation for future growth. Before discussing our progress for the period, I would like to briefly touch upon the industry outlook, which remains an important focus market for us. The global power transmission and distribution industry continues to witness structural demand drivers, including grid modernization, replacement of aging infrastructure, renewable energy integration, and rising electricity consumption. The growing requirements of data centers, digital infrastructure, and industrial electrification are further reinforcing the need for reliable and efficient power networks. Transformer bushings are critical components within this ecosystem, ensuring safe electrical connections between the transformers and external circuit. As utilities and transformer manufacturers focus on reliability, performance, and high-voltage applications, the demand for technically qualified and dependable bushing suppliers remains very important. For the company, these developments present opportunities across domestic and international markets, supported by our product capabilities, customer relationships, and ongoing expansion into high-voltage applications. Page 2 of 26 Yash Highvoltage Limited October 21, 2026 I would also like to give some strategic highlights. Our strategic priorities remain centered on expanding our international outreach, enhancing our technical credentials, and investing in capabilities that can support sustainable growth over the coming years. In the United States, our subsidiary, Yash HV USA, has entered into representation agreements with Ensales Electrical Associates, Gateway Power Sales, and EHV Solutions LLC. Together, these agreements extend our representation footprint to close to 27 states. This is an important step in strengthening our engagement with utilities, transformer OEMs, and other prospective customers. A wider local network should help us improve customer access, support product approval, and build relationships over time. We see these agreements as an important part of our broader effort to establish a stronger presence in the US market. We also achieved a significant technical milestone with successful completion of stringent seismic qualification testing for our IEEE compliant 138 and 230 kV OIP condenser transformer bushings. The company has become the first Indian OEM and one of a select group of global OEMs to achieve this qualification. This milestone reinforces our capabilities to serve customers in North and South American regions. The planned expansion of RIP bushing capabilities up to 550 kV is on track and intended to broaden our addressable product range and to enable us to cater to more demanding customer requirements globally. The greenfield facility at Jarod is an important element of this ambition, and our focus will remain on translating the investments made into common meaningful capabilities through a disciplined ramp-up. During the period, we completed a preferential allotment of equity shares and warrants aggregating to approximately 151 crores from marquee investors like Malabar Investment, WhiteOak, Motilal Oswal, ValueQuest, and Anantroop to name a few. Of this, 90.99 crores was received from the allotment of equity shares, and 15 crores was received upfront against warrants, taking the total fund received to approximately 106 crores. Page 3 of 26 Yash Highvoltage Limited October 21, 2026 The balance amount payable against the warrants will be received upon conversion/exercise within the applicable 18-month period. The proceeds will support the company's growth plan and ongoing capacity expansion initiatives. On the operational front, during the first half, we continue to strengthen our product and execution capabilities while taking important steps toward expanding our manufacturing footprints. We successfully tested our first 245 kV wall-through transformer bushing in-house and supplied the product to a leading public sector undertaking. This marks a meaningful addition to our product portfolio and demonstrates our growing design, testing, and execution capability in the high-voltage applications. We also successfully migrated to SAP S/4HANA globally while maintaining business continuity through the transition. This is an important step in strengthening our operating systems, improving process visibility, and supporting better coordination across business functions as the company grows in scale and complexity. These operational developments provide a foundation for the next phase of our growth, alongside strengthening our manufacturing and execution capabilities. We have also made progress in expanding our market access and improving our readiness to serve specialized international applications. With that, I would now like to hand over the call to Mr. Darshan Thakkar, our Executive Director, Finance, who will take you through our financial performance and business position. Over to you, Darshan. Darshan Thakkar: Thank you, Mr. Shah. Good evening, everyone, and a warm welcome once again to Yash Highvoltage Limited's H1 earnings call. For H1 FY27, revenue from operations stood at INR194.5 crores compar [Showing first 8,000 characters — download PDF for full document]
