Environmental

• Total global scope 1 and 2 greenhouse gas ("GHG") emissions were 198,110 tonnes of carbon dioxide equivalent ("tCO₂e"), a 15% increase year over year primarily driven by increased activity at Thompson Creek as it progressed through the restart phase.
• Emissions intensity per ounce of gold equivalent produced at the Company's two main operating mines, Mount Milligan and Öksüt, was 0.37 tCO₂e per gold equivalent ounce, which is well below the sector's weighted average emissions intensity of 0.80 tCO₂e per gold equivalent ounce.
• Centerra saw a 24% decrease in air emissions across seven pollutants compared to 2024. Additionally, in 2025, approximately 14,200 tCO₂e in emissions reductions were achieved through the renewable diesel pilot at Mount Milligan and the use of renewable energy credits at Öksüt.
• Öksüt earned several site-level certifications including ISO 50001 energy management system, ISO 14046 Water Footprint and Zero Waste certifications, reinforcing efforts taken to improve energy efficiency, optimize resource use and reduce emissions.
