IHS Holding Limited (NYSE:IHS) ("IHS Towers") group, one of the largest independent owners, operators, and developers of shared communications infrastructure in the world by tower count, has today published its 2025 Sustainability Report.

The report covers sustainability activities from January 1, 2025 to December 31, 2025 and demonstrates IHS Towers' continued commitment to its stakeholders, including, but not limited to, its employees, customers, suppliers, local communities, regulators, governments and shareholders.

IHS Towers' vision is to help create a connected world, where mobile connectivity promotes continued economic growth and social development. The communications infrastructure it provides is vital to enabling that connectivity.

In 2025, IHS Towers continued to advance its four-pillar sustainability strategy – focusing on ethics and governance, environment and climate change, education and economic growth, our people and communities – as detailed in this report.

Sam Darwish, Chairman & CEO, IHS Towers, commented, "At IHS Towers, we remain committed to advancing digital inclusion and delivering meaningful impact through our four sustainability pillars. We believe mobile connectivity has the power to unlock significant social value, and we recognize the critical role it plays in expanding access to education and economic opportunity.

Our 2025 Sustainability Report highlights this impact, showcasing our community‑focused initiatives across Africa and Latin America. We are proud of the long‑term value we continue to create for our stakeholders and are pleased to share the progress we are making across key HSSE priorities, our Carbon Reduction Roadmap, and the $45 million we have invested in our communities since 2017."
