What Martifer SGPS SA does
Martifer SGPS, S.A. is a Portuguese publicly listed industrial holding company (Euronext Lisbon since June 2007) that operates three core business divisions. The Metallic Constructions division engineers, fabricates, and assembles structural steel, aluminum, and glass facade systems for large-scale infrastructure such as airports (e.g., Geneva Airport East Wing, Dublin Airport Terminal 2), stadiums (Santiago Bernabéu, Euro 2004 and Brazil World Cup venues), hospitals, commercial offices, bridges, and oil and gas facilities, executing under EN 1090-1 EXC4 and ISO 3834-2 certified processes from industrial units in Portugal, Romania, Angola, and Mozambique. The West Sea division operates the Viana do Castelo shipyard acquired under sub-concession in 2011, building, repairing, and converting vessels up to 37,000 tonnes and 190 meters in length, including Portuguese Navy Ocean Patrol Vessels (NRP Setúbal plus six additional NPOs), the World Explorer polar expedition cruise ship, and a ~€100M luxury cruise ship for Japan's Ryobi Holdings. The Martifer Renováveis & Energia division develops wind, solar, and hydrogen projects (over 1.5 GW developed globally), operates a 440 MW O&M portfolio in Poland, and participates in the GreenH2Atlantic 100 MW green hydrogen project in Sines and the Ocean Winds offshore wind partnership.
Revenue is generated almost entirely through project-based, multi-year contracts awarded via competitive tenders and direct enterprise sales, with no recurring SaaS or subscription pricing. The 2025 operational revenue mix is roughly 53% Metallic Construction (€156.5M), 44% Naval Industry (€129.4M), and 4% Renewables (€13.0M), with EBITDA of €32.2M (11% margin) and an order backlog of €662M (of which €448M Naval). Customers are diversified across government/defense (Portuguese Navy), energy majors (EDP, Galp, ENGIE), real estate developers (HRS, Hill International), cruise operators (Mystic Cruises, Ryobi), and infrastructure consortia, served through direct field-sales teams embedded in project design. The group operates across 11 countries with approximately 1,098 employees and ~32,000 tonnes/year of steel structure capacity.
