Revenue model

1. Metal Construction: Revenue from the design, fabrication, and assembly of steel structures, aluminium and glass facades, and industrial infrastructure for large-scale construction projects such as airports, stadiums, office buildings, bridges, and energy infrastructure.
2. Naval Industry: Revenue from shipbuilding (construction of naval vessels, cruise ships, patrol boats, expedition vessels, river cruise ships), ship repair, and ship conversion (e.g., LNG conversion). The West Sea shipyard builds vessels to order for domestic and international clients.
3. Renewables & Energy: Revenue from development, construction and sale of wind and solar farms (asset rotation model), operation and maintenance services for renewable energy and industrial plants, and energy infrastructure mounting. Martifer Renewables has developed over 1.5 GW across multiple geographies and manages 440 MW in O&M.

Partnerships

Three partnerships are on record, tiered core and minor.

• Ocean WindscoreStrategic or Co-development Partner · 24 July 2024Ocean Winds (50-50 joint venture between EDP Renewables and ENGIE, a global leader in offshore wind) and Martifer Renewables & Energy formed a strategic partnership to jointly participate in Portugal's first offshore wind auction. The partnership combines Ocean Winds' international offshore wind development and operations experience (including the WindFloat Atlantic floating offshore wind farm) with Martifer's deep knowledge of the Portuguese market and industrial capabilities.
• GreenH2Atlantic ConsortiumcoreStrategic or Co-development PartnerMartifer is part of the GreenH2Atlantic consortium developing a 100 MW green hydrogen production facility in Sines, Portugal. The consortium includes EDP, Galp, ENGIE, Bondalti, Vestas Wind Systems A/S, McPhy, Efacec, ISQ, INESC-TEC, DLR, CEA, and Axelera cluster. The project received PIN (Strategic Interest) status from AICEP and €30M in Horizon 2020 EU funding.
• Martifer Amal (Mozambique)minorStrategic or Co-development PartnerMartifer Amal was created in partnership in Mozambique as part of Martifer's international expansion into Sub-Saharan Africa. The partnership supports the execution of industrial construction projects in the region, including the Galp bulk liquid storage terminal in Beira.

Direct peers

• Fincantieri: Italy-headquartered global cruise and naval shipbuilder, the largest in Europe, operating shipyards comparable in scale to West Sea. Directly comparable to Martifer's West Sea division on both cruise ship newbuilds (similar to Ryobi/Mystic Cruises work) and naval/military vessels (Portuguese Navy NPO).
• Severfield: UK-listed structural steel contractor that fabricates and installs steel structures for major infrastructure, commercial, and industrial projects. Directly comparable to Martifer Metallic Constructions on scope of work (steel fabrication for airports, stadiums, commercial buildings) and customer type (tier-1 contractors).
• Chantiers de l'Atlantique: French cruise ship and naval vessel builder (Saint-Nazaire shipyard). Direct cruise-ship peer to West Sea, operating at similar scale of large-vessel newbuilds for international cruise operators.
• Meyer Werft: German private shipbuilder specializing in complex cruise and expedition vessels. Direct comparable to West Sea's niche in expedition cruise ships such as the Mystic Cruises World Explorer and high-spec luxury cruise vessels like the Ryobi contract.
• Navantia: Spanish state-owned naval shipbuilder with shipyards for military and commercial vessels, including patrol boats and frigates. Direct peer to West Sea on naval/defense work (e.g., Portuguese NPO class) and competes in the same European naval market.
• Waagner-Biro Stage Systems: Austrian-headquartered steel engineering and construction specialist with global projects in steel structures, facades, and stage engineering. Comparable to Martifer Metallic Constructions on bespoke steel and facade engineering for complex architectural projects (e.g., EDP headquarters, Bilbao Museum).

Broad incumbents

• EDP Renováveis: Portuguese-headquartered global renewable energy developer — Martifer Renewables' closest peer on onshore wind asset rotation, and a key customer/partner (Ancora Wind, 171.6 MW) and consortium member (GreenH2Atlantic, Ocean Winds JV partner).
• Voestalpine: Austrian-headquartered steel manufacturer with downstream construction and railway infrastructure businesses. Overlaps with Martifer on high-grade steel processing (AARM 4.0 R&D) and steel structure fabrication, though much larger and more vertically integrated.
• ArcelorMittal: Global steel manufacturer whose structural steel products feed the construction supply chain. Provides input materials for Martifer's steel-structure fabrication business and represents the upstream boundary of Martifer's value chain.

Regional players

• Acciona Energía: Iberian-based renewable energy developer with wind/solar and emerging hydrogen projects. Comparable geographic and asset-rotation strategy to Martifer Renewables, though operating at much greater scale.
