METLEN Energy & Metals: ESG Sustainability & Performance Report 2023

Athens, Greece – 18 July 2024 – The management of the Sustainable Development, as an integral part of METLEN Energy & Metals' (formerly MYTILINEOS) business model, remains a key driver in enhancing the Company's ability to achieve business and economic growth, alongside its commitment to the Global Sustainable Development Goals.

As stated by the Chairman and CEO, Evangelos Mytilineos, in his introductory message in the Company's 2023 Sustainable Development and ESG Performance Report, "Our Sustainable Development strategy incorporates policies that are vital for our long-term success and competitiveness across economic, social, and environmental dimensions. Specifically, the hybrid intensity KPIs we monitor, which primarily reflect the relationship between our environmental and economic performance, continued to decline for the fourth consecutive year, indicating that the enhancement of our economic capital value (increased net profits) is achieved with a lower impact on the natural resources we use in our operations. Indicatively, I mention, the reduction of our CO₂ emissions (Scope 1 & 2) and the reduction of the water consumption, per million net profits, by 80% and 77% respectively, using 2020 as the base year."

In 2023, the company continued to demonstrate remarkable consistency in high ESG performance, reaching new heights. Notably, METLEN:

• Is the only Greece-based company selected to participate in the Dow Jones Sustainability Index Emerging Markets for the second consecutive year.
