In 1971 Metka was privatized and in 1973 its shares were listed on the Athens Stock Exchange, a move which was followed by acquisitions that enabled Metka to become a contractor for large-scale projects.
The transition of Metka from a private company to a publicly traded entity in 1971 set the stage for its listing on the Athens Stock Exchange two years later. The subsequent acquisitions allowed Metka to expand its portfolio and secure major contracts for large-scale construction projects.
