TSK

What TSK does

TSK (TSK ELECTRÓNICA Y ELECTRICIDAD, S.A.) is a Spanish engineering, procurement, and construction (EPC) contractor headquartered in Gijón, Asturias, founded in 1986 and listed on the Spanish Stock Exchange (BME: TSK) following its May 2026 IPO. The company delivers large-scale energy and industrial infrastructure projects across more than 30 countries, with international sales representing over 96% of revenue. Its portfolio spans solar energy (both photovoltaic and concentrated solar power using proprietary SKAL-ET parabolic trough technology acquired via Flagsol in 2013), combined cycle gas turbine plants, long-duration energy storage systems (LAES with Highview Power and ETES molten salt systems), hydrogen production and integration, electrical substations and transmission infrastructure, and materials handling solutions for mining and ports through its PHB Weserhütte subsidiary.

TSK generates revenue primarily through three streams: full-service EPC contracts (the largest stream, with project values typically ranging from tens to hundreds of millions of euros and recognized over multi-year execution horizons), post-construction operations and maintenance services (e.g., the 6-year Shagaya O&M contract), and early-stage engineering and project management services (e.g., the Fermi America Project Matador Phase 2 contract). The go-to-market is direct enterprise sales via competitive bidding, with target clients including utilities, independent power producers, governments, and industrial developers. The customer base spans major names such as Fermi America, Comisión Federal de Electricidad (CFE), OPC Energy, ACWA Power, AES, ArcelorMittal, and ENAGAS, with recent strategic focus on the hyperscale AI data center power segment. FY2025 revenue was €1.035 billion with EBITDA of €99.7 million (up 37% YoY), and the IPO implied a market capitalization of approximately €605 million.
