"Hogan Lovells advised Soletanche Freyssinet and its subsidiary Nuvia (VINCI Construction) on the acquisition of Spanish nuclear services provider Marsein. The sellers were advised by Spanish law firm Garrigues and investment bank Arcano."

Hogan Lovells advised Soletanche Freyssinet and its subsidiary Nuvia, the specialist nuclear-services arm of VINCI Construction, on the acquisition of Spanish nuclear services provider Marsein. The sellers were advised by Spanish law firm Garrigues and investment bank Arcano. The transaction concerns the acquisition of Marsein, one of Spain’s leading nuclear service providers, specialised in mechanical maintenance, welding, decommissioning and waste-management services. Marsein brings decades of experience in major Spanish reactor projects and decommissioning initiatives, including participation in Spain’s first nuclear 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 will allow Marsein to broaden its maintenance and decommissioning capabilities by incorporating Nuvia’s technological expertise and resources into its service offering. Hogan Lovells represented Soletanche Freyssinet and Nuvia with a team composed by: Alex Dolmans (partner, Corporate M&A), Hugo Muñoz (senior associate, Corporate M&A), Sara González (junior associate) and Cristina Adanero (junior associate). Dune Morris represented Soletanche Freyssinet with: Amauri Costa (lead M&A counsel, international transactions). Garrigues represented the sellers in the transaction. Arcano advised the sellers in its role as investment bank.
