Metlen Aluminium Production Fell in 2025 as Power Costs Hit Metals Profits

Metlen

Metlen aluminium production declined in 2025 as higher European electricity costs squeezed margins across the Greek group’s metals business. The company produced 232,000t of aluminium during the year, down 2% from 2024.

Primary aluminium output fell by 4% to 176,000t, outweighing a 2% increase in recycled aluminium production to 57,000t. Alumina output also slipped by 1% to 855,000t.

Metlen aluminium production weakness shows how European smelters remain exposed to energy costs even when aluminium prices are firmer. Higher power prices reduced operating profits and weakened the earnings contribution from the metals segment.

Aluminium Revenue Rose but EBITDA Fell Sharply

Metlen’s metals revenue increased in 2025, but profitability fell because margins weakened. Aluminium revenue rose by 4% to €646mn, while EBITDA from aluminium dropped by 40% to €127mn.

Alumina showed a similar pattern. Revenue from alumina production increased by 4% to €206mn, but product-linked EBITDA fell by 9% to €79mn.

The result highlights the margin pressure facing European aluminium producers. Stronger aluminium prices, supported by trade tensions and US import tariffs, were not enough to offset higher electricity costs across the region.

Metlen’s metals unit contributed 13% of group revenue. However, weaker metals earnings weighed on the company’s broader industrial performance.

Gallium Project Adds Strategic Value Beyond Aluminium

Metlen’s group EBITDA fell by 30% to €753mn in 2025, despite a 25% increase in revenue to €7.1bn. The decline reflected project execution-related losses, mainly tied to the Protos strategic energy and resource project in the UK.

Revenue growth was supported by stronger performance in renewables, infrastructure, and concessions. This helped offset some weakness from metals, but did not prevent the group-wide earnings decline.

Metlen is also moving into critical materials. The company plans to produce up to 50 t/yr of gallium by 2028 after reaching full capacity, supported by a €90mn investment from the European Investment Bank.

This gallium project could give Metlen a more strategic role in Europe’s critical minerals supply chain. Gallium is important for semiconductors, power electronics, optics, defense systems, and advanced communications technologies.

The Metalnomist Commentary

Metlen’s results show that Europe’s aluminium industry still faces a structural energy-cost problem. The gallium project gives the company a higher-value strategic materials angle, but its aluminium margins will remain tied to power competitiveness.
