Kindly take the information on record. Thanking you, Yours faithfully, For Ion Exchange (India) Limited Nikisha Solanki Company Secretary & Compliance Officer ACS-50894 Encl.: As stated above ANNUAL REPORT 2025-26 Business Responsibility & Sustainability Report FOREWORD At Ion Exchange, our Environmental, Social, and Governance strategy is anchored in a systems-level purpose: conserving the planet’s most vital resources through comprehensive water and environmental management solutions. Operating across the full lifecycle of liquid, solid, and gaseous waste generated by industries, institutions, households, and communities, in both urban and rural geographies – we deliver advanced, sustainable technologies that directly address the drivers of climate change, generating enduring co-benefits for people and ecosystems. Over six decades of sustainable innovation have positioned us as the single largest solution provider in the water and environment sector. Across this journey, our work has consistently advanced multiple Sustainable Development Goals, reflecting a long-held belief that responsible business growth and planetary stewardship are mutually reinforcing – not trade-offs. This Business Responsibility and Sustainability Report (BRSR) presents our ESG performance with full transparency. In a landscape where decarbonisation expectations are accelerating and stakeholder scrutiny is intensifying, we recognise that intention alone is insufficient. Progress must be measurable, accountable, and dynamically responsive to evolving science, societal and stakeholder expectations. Our sustainability commitments unite our employees, customers, partners, and the broader ecosystem in a shared mission of delivering lasting, inclusive value. FY 2025–26 demonstrated that growth and sustainability can scale together. We continued to reduce our carbon, energy, and water intensities – maintaining a consistent year-on-year improvement trajectory, while significantly expanding both our operations and our workforce. Operational resilience was strengthened, and sustainability was embedded not as a compliance layer but as a core driver of our growth strategy. Our focus remained steadfast: environmental stewardship, social well-being, and inclusive economic prosperity – advanced through collaboration, innovation, and continuous improvement. Sustainability is not a fixed destination. It is a continuous, evolving commitment – one that demands adaptive leadership and systems thinking at every level of the organisation. At Ion Exchange, we take pride in leading this journey: upholding rigorous governance standards, creating long-term stakeholder value, building trust and ensuring that the way we grow is as important as how much we grow.
