The acquisition is the latest move by First Names as it looks to establish itself as the largest independent provider of trust and corporate services.
Once Nautilus is integrated and rebranded, First Names will have nearly 800 employees operating across its network of 14 global offices.
Terms were not disclosed.
Founded in 1999 as Beachside Trust Company, the company rebranded to Nautilus Trust Company in 2000. Jason Cowleard joined as chief executive in 2006 and, along with his co-directors, has driven the company’s growth.
Mark Pesco, group managing director, private clients at First Names Group, said: “The acquisition of Nautilus is a significant milestone for the group. We are highly ambitious and have delivered exceptional growth over the last few years which would not have been possible without the hard work and dedication of our First Names.”
Ben Newman, managing director of First Names Jersey, said: “Nautilus is a great fit for us both commercially and culturally and I am really pleased to welcome the team to First Names Group. The acquisition will further strengthen our Jersey operation and I am excited about driving the business forward.”
