Hogan Lovells Advises Soletanche Freyssinet and Nuvia on Acquisition of Spanish Nuclear Services Company Marsein

"Hogan Lovells advised Soletanche Freyssinet and its nuclear-services subsidiary Nuvia on the acquisition of Spanish nuclear services provider Marsein. Dune Morris (Amauri Costa) acted as lead M&A counsel for Soletanche Freyssinet and Spanish firm Garrigues advised the sellers. The deal gives Nuvia a presence in Spain and combines Marsein’s decommissioning experience with Nuvia’s technology."

Hogan Lovells, Dune Morris and Garrigues advised the parties: Hogan Lovells advised Soletanche Freyssinet and its nuclear-services subsidiary Nuvia; Dune Morris (Amauri Costa) acted as lead M&A counsel for Soletanche Freyssinet; and Spanish firm Garrigues advised the sellers. The transaction involved the acquisition by Soletanche Freyssinet and its subsidiary Nuvia of Marsein, a Spanish nuclear services company specialised in mechanical maintenance, welding, decommissioning and waste-management services. Marsein brings decades of experience on major Spanish reactor projects and decommissioning initiatives, including participation in Spain’s first reactor decommissioning operations at Vandellós I, José Cabrera-Zorita and Santa María de Garoña. The acquisition enables Nuvia, which already operates in 16 countries, to establish a presence in Spain and allows Marsein to expand its maintenance and decommissioning capabilities by incorporating Nuvia’s technological expertise and resources into its services. Hogan Lovells represented Soletanche Freyssinet and Nuvia with a team composed by: Alex Dolmans (partner, Corporate M&A, Madrid); Hugo Muñoz (senior associate, Corporate M&A, Madrid); Sara González (junior associate, Corporate M&A); Cristina Adanero (junior associate, Corporate M&A).
