NKT

What NKT does

NKT A/S is a Danish power cable manufacturer founded in 1891 by Hans Peter Prior and listed on Nasdaq Copenhagen (ticker: NKT), headquartered in Brøndby, Denmark, with approximately 6,000 employees across more than 16 countries. The company designs, manufactures, and installs high-voltage (≥52 kV to ≥640 kV), medium-voltage (6–50 kV), and low-voltage (≤1 kV) cable systems, and is a recognized European leader in HVDC (High Voltage Direct Current) cable technology, having launched the world's first HVDC MI submarine cable in 1954 and the first superconducting cable in 2001. Operations span manufacturing sites in Denmark (Asnaes), Sweden (Karlskrona, Falun, Alingsås), Germany (Cologne, Nordenham), Czech Republic (Velké Meziříčí, Kladno), Poland (Warszowice, Knurów), and Portugal (Esposende, via SolidAl), supplemented by a joint-venture offshore cable factory in Taiwan (WECS, with Walsin Lihwa). NKT operates dedicated cable-laying vessels (NKT Victoria and the methanol-powered NKT Eleonora, with 23,000-ton capacity) and the NKT T3600 subsea trencher, enabling turnkey offshore project delivery.

The company generates revenue primarily through project-based hardware sales of HV cable systems to transmission system operators (National Grid, SSEN Transmission, Hydro-Québec), offshore wind developers (Ørsted, Dogger Bank Wind Farm), and distribution system operators (Mainova), supplemented by MV/LV cable sales through distribution channels, cable accessories (joints, terminations up to 550 kV), lifecycle services (installation, monitoring, repair, decommissioning), and technology consulting. Pricing is custom and quote-based, governed by cable length, voltage rating, installation complexity, and project scope, with multi-year contract durations. The 2026 launch of a dedicated Data Centres product line signals an intent to diversify beyond traditional utility and offshore-wind customers into AI-driven hyperscaler power infrastructure.

In FY2025 NKT reported revenue of EUR 2,722 million (+6% organic) with record operational EBITDA of EUR 390 million, and held an EUR 10.2 billion high-voltage order backlog, including the EUR 2.2 billion Eastern Green Link 3 HVDC contract signed in March 2026 (its largest single project ever) and the completed Champlain Hudson Power Express project in the US (May 2026). Capital allocation has skewed toward organic capacity expansion (Karlskrona extrusion tower, Alingsås accessories), the SolidAl acquisition for EUR 192 million, the Taiwan WECS JV, and a EUR 150 million green bond issued March 2026. A Czech Competition Office investigation into alleged anti-competitive practices in the Czech cable market — with proposed fines against NKT and five other manufacturers — represents the principal near-term regulatory overhang, with final decisions expected by 2027.
