- GEK TERNA Holdings, Real Estate, Construction S.A. is a leading Greek infrastructure group primarily engaged in construction, energy, and concessions across Greece, Central and Southeastern Europe, the USA, North Africa, and the Middle East. The company manufactures and provides services in construction contracting; infrastructure concessions including motorways, water and wastewater treatment, and social infrastructure projects; renewable energy production and electricity generation; waste management; and e-ticketing systems. Its activities encompass the development, procurement, and operation of energy projects including natural gas and renewable energy sources.
Founded in 1999 and headquartered in Athens, Greece, GEK TERNA operates through various subsidiaries, including the former renewable energy arm Terna Energy, which held the largest and most diversified renewable portfolio in Greece and projects in Bulgaria and Poland. In a major strategic development in 2024, GEK TERNA sold a 70% stake in Terna Energy to Masdar, the UAE’s clean energy leader, in a €3.2 billion transaction—the largest ever energy deal on the Athens Stock Exchange—while retaining and consolidating non-core assets such as waste management, e-ticketing, and construction within its group. In 2025, GEK TERNA entered a strategic partnership and merger in the electricity supply sector with Motor Oil, creating a vertically integrated structure aimed at expanding market presence and addressing energy transition challenges, supported by considerable investments.
More recently, GEK TERNA launched a significant capital return initiative by commencing an equity buyback program for up to 10% of its issued share capital and secured a €500 million bond issuance co-invested by the European Bank for Reconstruction and Development (EBRD). Proceeds from this bond finance renewable energy, battery storage, social infrastructure, and water projects across Greece, Romania, Albania, and Kosovo, further supporting GEK TERNA’s commitment to sustainable infrastructure and environmental standards. The company’s portfolio also includes long-term concession contracts for large-scale public-private partnership (PPP) projects including irrigation, multi-storey car parks, and motorways, underscored by investments exceeding €60 million in 2023-24 to boost growth in construction and infrastructure segments.
GEK TERNA’s recent financial performance reflects robust growth with adjusted EBITDA significantly increasing year-over-year, driven by higher concession revenues and operational efficiencies. The company targets continued expansion in core sectors leveraging strategic partnerships, capital market activities, and a diversified portfolio encompassing construction, energy, infrastructure concessions, and environmental services across multiple geographies.
This comprehensive strategic repositioning and ongoing capital investments position GEK TERNA as a dominant player in the infrastructure and energy sectors within Greece and the broader European region, with expanding footprint and enhanced capabilities following its 2024-25 transformative transactions and alliances.
