Sell-side advisory

Lyon – Alantra has acted as sole financial advisor to the founding shareholders and management team of Groupe Desegur, a specialist provider of inspection and compliance services, on the sale of a stake to Activa Capital, a leading French private equity firm. 

Groupe Desegur is a well-established player in the Testing, Inspection, and Certification (TIC) sector, with a strong presence in highly regulated verticals such as nuclear and healthcare. The company combines niche technical know-how with deep domain expertise, delivering transparency and operational integrity across critical business environments. 

Jérôme Breuneval, Managing Director at Alantra, said: “We are pleased to have supported the founding team of Groupe Desegur in this strategic transaction. The partnership with Activa Capital will provide the support needed to accelerate Desegur’s growth trajectory, while preserving the values and technical excellence that underpin its leadership in the TIC space.”

This transaction further underscores Alantra’s strong track record advising founder-led businesses and niche service providers in the TIC and Business Services sectors. It builds on past advisory to Mornington Partners on the sale of Rock Compliance to Andwis (H.I.G. Capital) and Industrial Service Solutions in the divestment of its Inspection Services division to Element Materials Technology.
