Good afternoon, everyone, and thank you for joining us for second quarter results call. Before we begin, on behalf of Aether, I wish you and your family a very happy and prosperous Diwali. It is a season for new beginning, and that feels right where Aether is today. Q2 is a solid quarter. It reflects disciplined execution, the strength of our product portfolio and the growing strategic role we play across all 3 business verticals. The macro environment remains volatile, but we have kept building momentum, and we are laying the foundation for our next phase of growth. Our CRAMS and CEM businesses continues to lead. Together, they now contribute over 65% of our sales. That comes from the continued ramp-up of our major CEM contracts and from new CRAMS projects we have added. Today, I want to focus on a few key developments: increased portfolio with Baker Hughes and our progress in semiconductor businesses. As you know, we already manufactured a few products for Baker Hughes at our dedicated Strata site, which is Site 4. We are not taking -- sorry, we are now taking this partnership a step further. We have commercialized an entire new set of oilfield industrial chemicals for Baker Hughes, which have been shipped in quarter 2 of financial year 2027, which is the current quarter under review. We have successfully finished the required minor modifications for one of the production streams in Strata site to accommodate these new products. We see great potential for these new products as we service Baker Hughes customers worldwide. This clearly showcases Aether's depth and long-term nature of this relationship as we envisage to become Baker Hughes's strategic partner of choice for future products and projects. This matters beyond one contract. Recent events have reminded the world how important energy security is. We expect oil and gas to attract significant investments over the coming years, and Aether is well placed to benefit. Oil and gas already accounts for 33% of our sales, and we expect it to remain a key growth driver. On the semiconductor business, we have moved quickly here since our last call. I am pleased to share that we have started our first commercial shipments to semiconductor customers from our existing production facilities. Volumes are modest today, but we are growing month-on-month basis. For us, this is a strong validation of our capability, our quality and the trust our customers place in us. Our new production block for this segment at the Magnum site is being equipped and is on track for commercial production from quarter 4 of financial year 2027. In terms of looking ahead, the execution at Magnum site and the expansion of our R&D facility are on track and in the several places ahead of schedule. We are working on a number of exciting opportunities and expect to conclude agreements with leading global companies over the coming quarters. Page 3 of 18 Aether Industries Limited October 30, 2026 None of this would have happened without our people. I want to thank every member of the Aether team for their commitment this quarter our customers and shareholders for their continuous confidence in us. With this, I will hand over to Aman, who will update you on Dow Silicones project, our ongoing client discussions and a new contract with leading global agrochemical company. Over to you, Aman. Aman Desai: Thank you, Rohan, and good afternoon, everybody. Welcome to this call. I'll s [Showing first 8,000 characters — download PDF for full document]
