FINANCIAL PERFORMANCE Management Commentary “Q1FY27 marks a positive start to the new financial year for Rishabh. Despite a mixed global environment, we remain focused on profitable growth, stronger business quality and building capabilities for sustainable long-term growth. Consolidated revenue grew 4.2% YoY in Q1FY27 and Consolidated EBITDA increased 17.3% YoY, supported by improved sourcing, operational efficiencies, favourable product mix and operating leverage. The EEI segment remains our primary growth engine in Q1FY27, delivering a robust 34.0% YoY growth & maintained EBITDA margins of ~24%. Our expanding product portfolio and customer reach remain key drivers of growth. At Lumel Alucast, we remained breakeven at operating level in Q1FY27. In HPDC, our priority is clear, we are not pursuing volume at the cost of profitability. Following the operational restructuring and exit from lower-margin contracts, our focus is on filling capacity with profitable, higher-value opportunities and rebuild sustainable business. The industry outlook remains structurally attractive, driven by investments in electrification, grid modernization, Mr. Dineshkumar renewable energy, and industrial automation. The rapid expansion of AI and data centres is also creating new Musalekar opportunities for energy measurement, monitoring and power quality solutions. Managing Director & We are also accelerating our global diversification, across the US, Africa and Southeast Asia, while continuing to Group CEO strengthen our presence in India and Europe. In parallel, we also continue to invest in new product pipeline across energy meters, medium-voltage products, automation and solar inverters, expanding our addressable market and strengthening our technology capabilities. Our priorities for FY27 remain clear, profitable growth, better product mix, new product development, deeper customer relationships, strategic geographic expansion and disciplined capital allocation.” Q1FY27 Standalone Financial Highlights Revenue (Rs.
