ABOUT THE REPORT

This is Hindustan Zinc Limited’s (Hindustan Zinc) sixth Integrated Annual Report developed as per the guiding principles of the International Integrated Reporting Council’s (IIRC) Integrated Reporting < IR> framework, now part of the IFRS Foundation.

Through such reporting, we go beyond statutory requirements to provide holistic information on our value creation processes, using the six capitals. We disclose details on our external operating environment, the material issues impacting our business and stakeholders, and our strategy to maximise value creation. We further capture insights on our corporate governance practices, through which we protect the interests of our stakeholders and ensure long-term value creation

Through such comprehensive and transparent reporting, we provide our investors with an additional lens to determine our performance and prospects. They can thus make informed decisions about their engagement with the Company.

REPORTING SCOPE AND BOUNDARY

This Report covers Hindustan Zinc’s financial and sustainability disclosures for the period April 1, 2024, to March 31, 2025. These cover our diverse operational assets, including mines, smelters, power plants and refineries across locations. We cover consolidated financial information and material issues relevant to our operations and our value chain partners, customers, communities and other stakeholders.

We have provided a five-year trend, wherever relevant, for the Key Performance Indicators (KPIs), including the Environmental, Social and Governance (ESG) Indicators. This will equip our investors to understand our value-creation process better and analyse our performance.

FORWARD-LOOKING STATEMENTS

This Integrated Report contains information to help investors and shareholders, debenture and other security holders to properly assess our prospects and take informed investment decisions. This Report and other statements - written and oral - that we periodically make, contain information that set out anticipated results based on the Management’s plans and assumptions. We have tried wherever possible, to identify such statements by using words such as ‘anticipate’, ‘estimate’, ‘expects’, ‘projects’, ‘intends’, ‘plans’, ‘believes’, and words of similar substance in connection with any discussion of future performance. We cannot guarantee that all projections will be fulfilled, although we believe we have been judicious in our assumptions. The achievement of results is subject to risks, uncertainties and even inaccurate assumptions. Should any known or unknown risk or uncertainty materialise, or should underlying assumptions prove inaccurate, actual results could vary materially from those anticipated, estimated or projected. Readers should take this into consideration. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise.
