CMS advises Hg on majority investment in 3E

03 Nov 2026 United Kingdom 2 min read

CMS has advised Hg, a leading investor in European and transatlantic software and services businesses, on its majority investment in 3E, a provider of renewable energy asset performance management software and technical advisory services.

Hg will acquire its stake from ReNew and minority shareholders, while members of 3E’s founding and management team will continue to hold a stake alongside Hg. Galvanize Climate Solutions will also join Hg as a minority co-investor. The transaction is subject to customary closing conditions and is expected to complete over the coming months.

Founded more than 25 years ago, 3E developed SynaptiQ, a software platform that helps owners and operators of renewable energy assets monitor and optimise performance and revenue. Hg’s investment will support further development of the platform’s AI capabilities and international expansion, particularly in the US.

The CMS team was led by Narinder Jugpal (CMS UK) and Philippe Hendrickx (CMS Belgium) and included Ga Hyee Lee (CMS UK); Vincent De Munck and Gauthier Blommaert (CMS Belgium); Benoît Gomel, Mailys-Claire Diogo and Clémence Godille Warnesson (CMS France); Winnie Shekhar, Rajat Jain, Ruhi Jain, Adarsh Joshi and Mukul Sharma (CMS INDUSLAW); Yushanta Rungasammy, Yonela Diko and Zanrie Linstrom (CMS South Africa); and Ignacio Cerrato, Ana Martín-Zamorano Moreno and Jaime Babío Castanedo (CMS Spain).

With over 400 private equity, corporate, tax and finance lawyers, the CMS Private Equity team advises clients across all stages of the investment lifecycle, from fund formation and investment structuring to acquisitions, portfolio management and exits.
