In 2025, we continued to strengthen our health and safety culture through programs that encourage our people to speak up, support one another and take personal ownership of safety every day. We also advanced important initiatives to foster a more inclusive, connected and equitable workplace, because we know that strong performance begins with engaged and supported teams. I am proud of the progress we have made and grateful to our employees and contractors whose efforts continue to move us forward.

As we build the next chapter of Eldorado’s growth, we remain focused on creating long-term value through responsible mining, with safety and sustainability at the core of everything we do.” 2025 Report Highlights and Achievements : (Organized by the four pillars of our Sustainability Framework) Safe, Inclusive and Innovative Operations At Eldorado, we prioritize a positive culture of health and safety where everyone values their own and others’ safety and well-being.

By maintaining open and transparent communication, providing competitive wages and benefits, prioritizing local hiring and procurement, contributing our fair share of taxes and royalties, and investing in community programs and infrastructure, we work hard to support the development goals of our host communities and governments. 81% of our employees reside in local and host communities; 77% of our contractors are sourced from countries of operations; $7.6 million in community investment, representing a 68% increase year over year; and $1.2 billion spent on local/national procurement with suppliers, representing a 47% increase year over year.

We work closely with our regional teams to understand local regulations and align our environmental practices to meet these requirements and our Sustainability Integrated Management System (“SIMS”) standards.
