Metlen Energy & Metals

What Metlen Energy & Metals does

Metlen Energy & Metals PLC is a Greek-listed industrial conglomerate operating across energy, metallurgy, defense manufacturing, and infrastructure concessions. Founded in 1990 (originally as Mytilineos) and dual-listed on the London Stock Exchange (LSE:MTLN, primary listing since August 2025) and Athens Stock Exchange, the company reported FY2025 revenue of €7.107 billion, a 25% year-over-year increase, and is now a constituent of the FTSE 100 and MSCI UK indices. The company is headquartered in Amaroúsion (Athens), Greece, employs between 5,001 and 10,000 people, and serves enterprise customers across European markets including the UK, Italy, Germany, France, Romania, Bulgaria, Cyprus, Ireland, and Australia.

The company's Energy Sector encompasses renewable project development and EPC contracting (solar PV with over 2 GW installed or under construction across the UK and Ireland), grid-scale battery energy storage systems using two-hour liquid-cooled LFP battery technology (1,500 MW/3,000 MWh pipeline via a 50/50 JV with PPC Group), LNG supply and trading (five-year Shell framework for 0.5–1.0 bcm annually from 2027 to 2031), and integrated utility operations. The Metallurgy Sector covers the full aluminum value chain through Aluminium of Greece (primary smelting, operating since 1966 in Viotia), European Bauxites (mining), and EP.AL.ME. (rolling products). Notably, the company achieved Europe's first integrated bauxite-to-gallium production in January 2026—a strategically critical raw material where China controls 98% of global refining capacity—targeting commercial scale of 50 tonnes annually by 2028 under a €295.5 million investment program. The Defense Manufacturing vertical, anchored by the M Technologies Hub in Volos (100,000 sq.m. across six production units, targeting 1,000 employees by 2028), produces 200 LEOPARD 2A8 tank assemblies for KNDS Deutschland through 2031 and the VBCI PHILOCTETES infantry fighting vehicle via exclusive technology transfer from KNDS France, with additional collaborations with Naval Group, Raytheon, and TKMS.

Revenue is generated primarily through negotiated B2B enterprise contracts: one-time hardware sales for metals and defense components, recurring utility income and infrastructure concession arrangements, project-based EPC contracting for renewables and storage, and asset rotation through periodic portfolio sales to institutional investors (e.g., 283 MW UK solar portfolio sale to Schroders Greencoat in February 2026, following a 110 MW sale in 2024). Pricing is project-specific and not publicly disclosed. Customers span utilities, defense OEMs, industrial metals buyers, and institutional renewable energy investors across Europe. Recent structural moves include a €600 million share buyback program announced June 2026, the Q1 2026 "Third Era" corporate restructuring consolidating energy operations into the M RESET platform, and €600 million in senior notes issued in November 2025 to support the expansion pipeline.
