Grant Thornton to expand with Switzerland, Liechtenstein and Channel Islands

Grant Thornton multinational platform to expand to include Switzerland, Liechtenstein and the Channel Islands
CHICAGO, ZURICH and JERSEY, June 17, 2025 — Grant Thornton Advisors LLC (Grant Thornton Advisors) today announced agreements to expand the multinational platform it formed in January with Grant Thornton Ireland. The platform will now include Grant Thornton Switzerland/Liechtenstein and Grant Thornton in the Channel Islands (known as Grant Thornton Limited, Channel Islands).
Earlier this year, Grant Thornton Advisors announced transactions to join the platform with UAE, Luxembourg, the Cayman Islands and the Netherlands. Through this rapidly growing multinational platform, clients across three continents will have access to seamless and enhanced cross-border services, which are underpinned by investments in technology, people and quality.
Adding footprints in Switzerland, Liechtenstein and the Channel Islands strengthens the platform’s unified advisory and tax solutions, as well as its independent audit and assurance practices. It also creates a powerful network of professionals in European financial hubs — from Zurich and Geneva to Jersey and Guernsey, in addition to Bermuda, the Cayman Islands and UAE.
With the latest agreements, the Grant Thornton multinational platform will include approximately 13,500 professionals across nearly 60 offices stretching from the Americas across Europe to the Middle East. It is backed by an investor group led by New Mountain Capital — a growth-oriented investment firm with approximately $55 billion in assets under management.
The expanded platform will continue to be part of the Grant Thornton International Limited network, which comprises member firms in more than 150 markets worldwide.
“We are very pleased to have our colleagues in the Channel Islands, Switzerland and Liechtenstein join our differentiated and expanding platform,” said Jim Peko, CEO of Grant Thornton Advisors. “We’re building the world’s most talented team — delivering seamless offerings through an expanded footprint. The result: an unparalleled client experience and unmatched quality.”
“Today’s announcement represents further strong additions to our platform, with a shared focus on client centricity, quality and industry-service alignment,” added Steve Tennant, managing partner of Grant Thornton in Ireland. “We look forward to welcoming new colleagues across Europe as we expand in several of the world’s leading finance centers.”
Adam Budworth, managing partner of Grant Thornton Channel Islands, said: “This is an exciting opportunity to support our growth in the Channel Islands with access to new service offerings, technologies and investment capital. Joining the platform will only enhance the reputation of the Channel Islands on a bigger stage, while at the same time creating unique opportunities for our people.”
“I am delighted about this positive development and am convinced that it is the right step for our firm in the current turbulent market environment,” said Erich Bucher, CEO of Grant Thornton Switzerland/Liechtenstein. “It opens up completely new perspectives for us and will enable us to push ahead with our growth strategy much more quickly.”
“The Grant Thornton platform is supercharging itself with the quality, talent and advanced technologies that clients need and want,” said Andre Moura and Nikhil Devulapalli, managing directors at New Mountain Capital. “The addition of these two firms — both well-respected in their markets and renowned for their finance expertise — will continue to elevate Grant Thornton’s world-class and wide-reaching financial services offering.”
Both transactions are expected to close later this year, subject to regulatory approvals and other standard closing conditions.
