METLEN reorganised its Metals Sector into three strategic pillars, repositioning to a broader European strategic materials and industrial technology platform.

1.    Vertical Aluminium Value Chain

2.    Critical Raw Materials & Circular Metals

3.    M Technologies (defence and industrial applications)

1.   KEY FINANCIAL FIGURES

2.   SECTORAL OPERATIONAL UPDATES

2.1. Energy Sector

·    Strategic agreements with PPC Group and Tsakos Group have strengthened METLEN's storage pipeline, which now stands at c.2GW across Greece and international markets.

·      METLEN signed an MoU with Shell for supply of up to 1 bcm p.a. during 2027-2031.

·      A 283MW UK solar portfolio was sold to Schroders Greencoat, demonstrating continued execution of the Asset Rotation strategy.

2.2. Metals Sector

The Metals Sector benefited from supportive aluminium pricing, resilient premia and the advantages of METLEN's fully integrated production model.

·   During the quarter, METLEN advanced its bauxite, alumina and aluminium investment program, supported by financing from the European Investment Bank, including Europe's first industrial-scale gallium production facility. Strong offtake interest is being observed from the US, Japan and Europe, with offtake agreements expected soon. Initial production expected in 2027, ramping up to 50 tpa by 2028.

·    Similarly, the Circular Metals initiative is progressing well, supported by positive pilot plant results, with the optimization of the expansion plan expected to be finalized later this year

·    M Technologies continued to scale during the quarter, through the acquisition of an additional facility (former NK Trailers), bringing total operational units to six, ahead of initial targets, supporting rising demand for defence systems. The Company also strengthened its collaboration with Naval Group, delivering equipment for the FDI frigate programme and signing a new MoU for potential cooperation on submarine and surface vessel projects.

2.3. Infrastructure and Concessions Sector

The Infrastructure and Concessions Sector continued to perform in line with management expectations, with revenues almost doubling in Q1 2026 versus Q1 2025, while all projects progressed smoothly and on schedule. METKA ATE maintains a leading market position, supported by strong recognition and a total backlog exceeding €2.2bn, including projects at an advanced contracting stage, while actively pursuing new opportunities. Together with M Concessions, it continues to expand its footprint in PPPs and major infrastructure projects, supporting long-term value creation.

In February 2026, METLEN agreed to participate with a 24% stake in the Concessionaire DIKTAION PARACHORISEIS Single-Member S.A. at the "Northern Road Axis of Crete (ΒΟΑΚ) - Chania - Heraklion Section", while METKA ATE agreed to participate with a 30% stake in the Construction Joint Venture of the same project. Within the first quarter, METKA signed contracts for the construction of the Casino and Hotel complex in Maroussi, as well as the Holocaust Museum in Thessaloniki. It was also declared preferred bidder for the Skaramangas Triple Interchange project.

Outlook

The first quarter of 2026 confirms METLEN's strong positioning across its diversified business model, with all Sectors contributing to growth.

The Company continues to operate in an environment shaped by heightened geopolitical tensions and ongoing conflicts, which impact energy markets, supply chains and defence demand. Nevertheless, these conditions also underscore the strategic importance of METLEN's synergistic business model, further strengthened by its activities in energy security, critical raw materials, and defence solutions.

Looking ahead, management maintains a cautiously optimistic outlook for 2026, supported by a strong project pipeline, increasing demand and prices across core sectors and continued execution of the Company's investment program.

Further details will be provided at the Annual General Meeting scheduled for 21 May 2026, in line with the Company's long-standing practice.
