Nordex SE, the Hamburg-headquartered wind turbine manufacturer listed on the MDAX and TecDAX, has signed an agreement to acquire C1 Connections, a Dutch engineering company specialised in tower connection technology. The deal brings the patented C1 Wedge Connection™ onshore technology, its related intellectual property portfolio, and a core structural engineering team into the Nordex Group. Financial terms were not disclosed, as the parties agreed to keep those details confidential. The acquisition signals Nordex's continued push to expand its proprietary tower engineering capabilities across its global onshore wind business.

Key Points

  • Nordex SE (0MEC), listed on the MDAX and TecDAX of the Frankfurt Stock Exchange (ISIN: DE000A0D6554)
  • Nordex has signed an agreement to acquire C1 Connections, a Dutch tower connection engineering firm founded in 2017
  • Financial terms were not disclosed; the transaction excludes C1 Connections' offshore wind activities, which will continue in a newly established separate entity
  • Investors may watch for further detail on integration timelines and any commercially disclosed impact on Nordex's tower product range

Patented C1 Wedge Connection™ Technology and IP Portfolio Transfer to Nordex Group

The core asset of the transaction is the patented C1 Wedge Connection™, a system for joining wind turbine tower sections that allows tubular components to be manufactured in numerous locations worldwide. This design is particularly relevant for developers seeking to meet local content requirements in markets where domestic manufacturing is a contractual or regulatory obligation. Founded in 2017 and backed by investors Shift Invest and Dolfin Capital, C1 Connections developed the technology to industrial-scale readiness. The acquisition transfers the full intellectual property portfolio and associated engineering know-how to Nordex, alongside the specialist team that created it.

How the Acquisition Fits Nordex's Onshore Turbine Strategy Across 40 Markets

Nordex has commissioned more than 67 GW of wind power capacity across more than 40 markets since 1985 and recorded consolidated sales of approximately EUR 7.6 billion in 2025. The group employs more than 11,100 people and operates manufacturing facilities in Germany, Spain, Brazil, India, the United States, and Türkiye. Its product portfolio focuses on onshore turbines in the 4 to 7 MW-plus classes, designed for markets with limited available space or constrained grid capacity. The C1 Connections acquisition is positioned to broaden the range of tower solutions Nordex can offer for selected projects, complementing its existing turbine and tower engineering expertise.

Offshore Wind Activities Excluded as C1 Connections Establishes Separate Entity

The announcement states that C1 Connections' offshore wind activities fall outside the scope of the transaction. Those activities will be continued within a separate, newly established entity, meaning Nordex is acquiring only the onshore-focused engineering team, technology, and IP. This structural carve-out reflects a deliberate scoping decision by both parties and limits the breadth of capabilities transferring to Nordex. Jasper Winkes, Founder and CEO of C1 Connections, noted in the announcement that his team is focused on continuing the technology's development as part of the Nordex Group, having worked to bring it to industrial-scale readiness.
