Shoosmiths has advised the selling shareholders of AVK Power Solutions ("AVK”), one of Europe’s largest and fastest-growing suppliers of power solutions for data centres and AI infrastructure, on the sale of their shares to the Swiss based private equity house, Partners Group, who will acquire a majority stake in the business and intends to invest more than $1 billion of equity, backed by debt financing, to accelerate AVK’s expansion.

Headquartered in the UK, AVK designs, installs and maintains power solutions for data centres, including back-up power generation, behind-the-meter energy infrastructure and modular electrical power units. The business has delivered more than 20,000 projects and installed approximately 3.5 GW of power to date, with operations spanning established and emerging data centre markets across Europe.

The investment will support AVK’s continued growth as demand for data centre infrastructure accelerates across Europe, including the development of the business into an infrastructure platform providing long-term Energy-as-a-Service solutions to data centre operators. AVK’s management team will retain a minority stake in the business.

Shoosmiths advised AVK on all aspects of the transaction. The team was led by Partners Stephen Porter and Claire Checketts, with support from Principal Associates Adam Frost and Sarah Mitchell, Senior Associate George Peyton, Associates Olivia Ashcroft and Sam Enderby, and Trainee Solicitor Maddie Fretwell. Partner Laura Gould advised on tax and Partner Stuart Lawrenson on employment matters.

Stephen Porter, Partner at Shoosmiths, commented: “We are delighted to have advised AVK’s shareholders on this key transaction. AVK has a strong position in a market that continues to see significant appetite for growth, and this investment will enable the business to meet this demand with new innovations. We look forward to seeing AVK continue to deliver the best outcomes for its clients and partners alongside Partners Group.”

Ben Pritchard, Chief Executive Officer of AVK, commented: “AVK’s new partnership with Partners Group and the addition of capital to our power solutions portfolio, is an exciting new chapter for the business, allowing us to turn speed-to-power from an ambition into action and for AVK to meet our customers exactly where the data centre sector and power market demands. We are grateful to the whole team at Shoosmiths for their dedication and support in helping deliver this transaction. Their expertise and calm, pragmatic and solutions-focused approach throughout, meant they proved to be trusted advisers to AVK from start to finish.”
