Direct peers

• Norsk Hydro: Vertically integrated bauxite-alumina-aluminum producer headquartered in Norway with significant renewable energy generation tied to its smelting operations. Closely comparable to METLEN's Aluminium of Greece in integrated primary aluminum production combined with energy ownership.
• Alcoa Corporation: Global primary aluminum producer with bauxite mining, alumina refining, and aluminum smelting assets. Direct peer to METLEN's Aluminium of Greece and European Bauxites in the upstream and primary aluminum value chain.
• Emirates Global Aluminum (EGA): Privately held, vertically integrated bauxite-alumina-primary aluminum producer based in the UAE. Operates one of the five primary aluminum smelters globally and is a direct competitor to METLEN in primary aluminum supply, though it benefits from cheaper energy.
• Hindalco Industries (Aditya Birla Group): India-based integrated aluminum and copper producer covering bauxite, alumina, primary aluminum, and downstream rolled products. Comparable business model to METLEN's vertically integrated Metals Sector.

Broad incumbents

• Rio Tinto (Aluminum segment): Diversified global miner with a sizeable aluminum and bauxite segment (formerly Alcan) alongside iron ore, copper, lithium, and other minerals. Comparable to METLEN in primary aluminum and bauxite, though vastly larger and more diversified.
• South32: Diversified metals and mining company with aluminum, alumina, copper, zinc, nickel, manganese, and metallurgical coal operations. The aluminum segment (including Brazil Alumar) is directly comparable to METLEN's primary aluminum business.
• China Hongqiao Group: World's largest aluminum producer with vertically integrated bauxite-alumina-aluminum operations and captive coal-fired power generation in China. Comparable in scale and vertical integration, though operating in a different regulatory and energy cost environment.
• Iberdrola: Global renewable and integrated utility with a large RES portfolio and BESS investments across Europe and the Americas. Comparable to METLEN's energy generation, renewables, and storage growth strategy.

Emerging players

• Constellium: Specialty aluminum products manufacturer focused on aerospace, automotive, and packaging rolled and extruded products. Comparable to METLEN's downstream value-added aluminum activities, particularly through M Technologies.

Regional players

• Public Power Corporation (PPC) / DEI: Greek integrated utility with generation, supply, and RES operations and a major PPA counterparty to METLEN. Comparable to METLEN's Protergia retail and integrated utility business in the same Greek market.
