A&O Shearman has advised Cadeler A/S on its acquisition of Menck from Acteon, a portfolio business of Buckthorn Partners and One Equity Partners. The transaction is based on an agreed enterprise valuation equivalent to EUR501 million.

Cadeler A/S is a global leader in offshore wind turbine transport and installation and is listed on the New York Stock Exchange (CDLR) and the Oslo Stock Exchange (CADLR).

The team was led by partners Paul Dunbar, Dan Graham and senior associate Antony Dean, supported by associate Livia Gauntlett and trainee Fiona Ngu, with additional specialist advice provided by partners and teams across A&O Shearman's global network. 

“We are delighted to have supported Cadeler on this acquisition, which brings Menck's specialist foundation installation technology and engineering expertise together with Cadeler's offshore wind installation platform. As the offshore wind sectors matures, developers are increasingly looking for integrated installation solutions, and we are proud to have acted on a transaction at the very forefront of this.”

Dan Graham, a senior partner in A&O Shearman's global private equity practice, added: “This deal sits at the intersection of strategic and private capital investment in renewable infrastructure, energy and power. It is an area where we continue to advise the most sophisticated strategic acquirers, financial investors, credit and capital solutions sponsors, infrastructure funds and their portfolio companies on the most complex cross-border deals in the market, and the combination of listed-company, multi-jurisdictional and financial sponsor considerations here is characteristic of the work we are seeing across the sector.”

Menck is a leading global provider of specialist equipment and technology solutions for offshore foundation installation, headquartered in Kaltenkirchen, Germany, with teams across Europe and Asia-Pacific. 

Acteon delivers data-driven, engineering-led solutions across the lifecycle of offshore energy infrastructure.
