The story

The company was founded by Evangelos Mytilineos, who amalgamated his family's metallurgy businesses, as Mytilineos Holdings in Greece in 1990.

It acquired a series of copper, zinc and lead mines in Europe in early 1990s and was listed on the Athens Stock Exchange in 1995.

The company then acquired a large construction business, Metka, in 1998, and it expanded into the energy sector in the early 2000s.

In June 2024, the company rebranded and updated its corporate identity to Metlen Energy & Metals. It then transferred its primary listing from the Athens Stock Exchange to London in August 2025.
