- Obrascón Huarte Lain, S.A. (OHLA) operates as a global infrastructure group specializing in the design, engineering, construction, maintenance and operation of large-scale civil engineering works and buildings; it provides industrial plant services including oil and gas, renewable energy, mining, cement and fire-fighting systems; and offers concessions development for toll roads, transport infrastructure, ports and marinas, with operations spanning the United States, Canada, Mexico, Chile, Peru, Colombia, Spain, Central and Eastern Europe, Northern Europe and other international markets. Headquartered in Madrid, Spain, at Paseo de la Castellana 259-D, the company traces its origins to 1911 with the founding of Sociedad General de Obras y Construcciones Obrascón, S.A. in Bilbao, followed by key mergers in 1998 with Huarte and in 1999 with Construcciones Lain, forming the modern entity; it maintains subsidiaries such as OHLA USA, based in New York, focusing on complex infrastructure and vertical construction projects. OHLA serves public and private-sector clients across construction, industrial and services segments, including building renovation, technical advisory, IT management consultancy, security and fire protection systems installation, water treatment, fossil fuel power plants, real estate development, hotels, leisure centres and car park operations. Recent developments include the successful completion of a €50 million capital increase in May 2025, fully subscribed with significant oversubscription to bolster financial strength and support its 2025-2029 Strategic Plan targeting over €5 billion in revenues and €300 million in EBITDA by 2029; a second €50 million capital increase announced around the same period as part of ongoing recapitalization efforts that reduced leverage from over 11x to 2.2x; record order book growth to €8,599.9 million as of September 2025, up 1.4% from year-end 2024, driven by major projects like the BR-040/495 Highway concession start-up, port expansions in Barcelona and Puerto del Rosario, Florida infrastructure awards exceeding $450 million via OHLA USA including Port of Miami work and highway widenings, and advancements in high-value initiatives such as Centro Canalejas Madrid and the Purple Line light rail; strengthened EBITDA to €113.2 million (+30.3%) in the first nine months of 2025; and resolution of long-standing arbitration including a €315 million award from Qatar Railways while divesting non-core assets like its 25% stake in the CHUM PPP project in 2024.
