I'm pleased to report that financial year 2027 started as per our plan with growth in the core, discipline on the balance sheet and the new strategic vectors opening up that Aman and I are genuinely excited to talk to you about today. Site 3++ block that we had commissioned in February 2026 is ramping up as per our expectations. The Baker Hughes contract continues to scale and our CRAMS and contract exclusive manufacturing pipeline is the deepest it has ever been. Our two contract-led model, contract exclusive manufacturing, CEM, and Contract Research and Manufacturing Services, CRAMS, have moved from promise to backbone. CEM runs at EBITDA margins north of 28% to 30%, so every point of mix that shifts towards this model makes our earnings both larger and more resilient. Under CEM sits real contractual relationships, long-term take-or-pay/minimum volumes offtake agreements with global leaders such as Baker Hughes, Seqens, Saudi Aramco, and Milliken. In Q1 FY 2027, we have onboarded 10 new marquee clients and cleared more than nine customer and certification audits. In financial year 2027, the demand signal is the strongest we have ever seen from order visibility, rising urgencies from customers in the West, and the CRAMS to CEM conversion pipelines that keep deepening. My headline is simple. CEM and CRAMS are compounding, getting more profitable as they scale, and we have a clear line of sight to these two models contributing 70+ of our -- percentage of our revenue in the next couple of years. The core business is performing well, but I do not want this call to be only about the good quarter. I want to use today to tell you where Aether is heading next, and that brings me to what I believe is the most exciting chapter in this company story since we listed. Since last 13 years, India -- Aether has done difficult chemistries that we feel few companies in the world can do and have done it in India. Today, the single largest material science opportunity of this decade is the semiconductors behind AI and 5G revolution. And here is the exciting part. Some of the chemistries those semiconductor segments depend on is a chemistry in Aether’s core competencies. Every time the world moves faster, 5G, AI data centers, high frequency computing, the circuit board itself becomes the bottleneck. At this speed, ordinary board material leaks, gets overheated, and distorts signal. The industry’s answer is a class of advanced low dielectric materials, resins, and coupling agents engineered to carry high frequency signals with almost no loss. This goes into the copper-claded laminate and high-speed printed circuit boards inside every 5G base station, every AI server, and every advanced device. This is one of the fastest growing corners of the electronic materials. Those light, low dielectric materials are built from the small family of specialty monomer [Showing first 8,000 characters — download PDF for full document]
