Hindustan Zinc Limited, the world's largest integrated zinc producer and among the top ten global silver producers, has signed a Memorandum of Understanding (MoU) with Group Nirmal to establish a zinc wire manufacturing facility at its flagship Zinc Industrial Park located at Khankhala, Bhilwara district of Rajasthan. The announcement was made on May 12, 2026, and the disclosure was filed in compliance with Regulation 30 of the SEBI (Listing Obligations and Disclosure Requirements) Regulations, 2015. The collaboration is aimed at furthering Hindustan Zinc's vision of building a robust downstream zinc manufacturing ecosystem in India focused on high-value industrial applications.

Key Highlights of the Partnership

The following table summarises the key details of the MoU between Hindustan Zinc and Group Nirmal:

Zinc Wire Manufacturing and Its Applications

Under the agreement, Group Nirmal will manufacture zinc wire products using Hindustan Zinc's Special High Grade (SHG) zinc. Zinc wire is a critical input for thermal spray coating and metallizing processes, where it is melted and sprayed onto steel surfaces to form a protective zinc coating. This process provides durable anti-corrosion protection to steel structures and critical assets, including:

• Bridges and transmission towers
• Railways and ports
• Pipelines and industrial installations exposed to aggressive environmental conditions

These coatings significantly enhance structural longevity, improve operational reliability, and reduce lifecycle maintenance requirements, making them an increasingly preferred solution for sustainable infrastructure protection.

About the Zinc Industrial Park

The Zinc Industrial Park proposal was first announced by the Honourable Chief Minister of Rajasthan, Shri Bhajan Lal Sharma, alongside Vedanta Group Chairman Shri Anil Agarwal at the Rising Rajasthan Global Investment Summit in December 2024. Developed in collaboration with RIICO, the park is a dedicated downstream manufacturing hub designed to integrate raw material availability with value-added zinc production. Strategically located near Hindustan Zinc's key metal operations, the initiative is expected to:

• Strengthen domestic supply chains
• Attract investments across galvanizing, die-casting, zinc alloys, zinc oxide, battery materials, and advanced zinc applications
• Support industrial growth, employment generation, and broader regional economic development in Rajasthan

Through this collaboration, Hindustan Zinc will enable assured raw material linkage and extend long-term ecosystem support for Group Nirmal's proposed operations at the park.

Leadership Commentary

Commenting on the partnership, Arun Misra, CEO & Whole-time Director – Hindustan Zinc, stated: "Zinc Park is a strategic initiative that reflects our long-term vision of creating a globally competitive and sustainable downstream ecosystem for zinc-based industries in India. Our partnership with Group Nirmal highlights the growing industry confidence in this transformative platform. Zinc wire manufacturing is a critical segment supporting corrosion protection and infrastructure longevity across sectors. Through strong industry collaborations, renewable energy integration and assured supply chain support, we aim to drive innovation, strengthen domestic manufacturing and create long-term industrial value."

Strengthening the Downstream Zinc Ecosystem

Group Nirmal's expertise in manufacturing and industrial solutions is expected to further strengthen Zinc Park's downstream ecosystem. The collaboration is anticipated to enhance operational efficiencies and support rising demand for advanced corrosion protection solutions across infrastructure and industrial sectors. Zinc's superior anti-corrosion properties make it a critical enabler of long-term infrastructure durability and sustainability. Zinc-based thermal spray coatings significantly extend the lifespan of steel structures, improve asset reliability, and reduce lifecycle maintenance costs — factors that are increasingly relevant as India continues to invest in infrastructure, renewable energy, transportation, and urban development.
