CHICAGO, PARIS, MADRID and BRUSSELS, September 29, 2025 – Grant Thornton Advisors LLC (Grant Thornton Advisors) today announced that Grant Thornton France, Grant Thornton Spain and Grant Thornton Belgium will be joining its rapidly growing platform.
The transactions with each firm underscore Grant Thornton Advisors’ seamless connectivity and capabilities across the Americas, Europe and the Middle East, building on the recently announced platform acquisitions of the Grant Thornton member firms in the United States, Ireland, the United Arab Emirates, the Netherlands, Switzerland, Liechtenstein, the Cayman Islands, Luxembourg and the Channel Islands.
Grant Thornton Advisors is supported by an investor group led by New Mountain Capital and initiated its multinational platform strategy in January 2025. The platform has pioneered a uniquely cohesive, multidisciplinary approach that delivers the highest quality cross-border services through a unified advisory and tax practice, as well as independent audit practices. With today’s announcement, eleven Grant Thornton member firms have banded together under a unified platform backed by the New Mountain Capital led investor group. And the platform looks to continue selectively welcoming the highest quality, most collaborative firms across strategic markets.
With the new additions, the Grant Thornton Advisors platform will accelerate growth in the French, Spanish and Belgian markets – representing high-value, strategic footprints that solidify the platform’s preeminence across Europe. Clients will benefit from access to an even more extensive array of industry expertise and innovative solutions, amplified by substantial investments in technology and talent.
Grant Thornton France stands as one of the premier accounting and advisory firms in a key global financial center. It has demonstrated consistent outsized growth, becoming one of the largest firms in the Grant Thornton International Limited (GTIL) network – with 2,800 employees across 24 offices.
The firm maintains a client roster ranging from CAC 40 and SBF 120 leaders to large corporations, as well as middle-market businesses. It is deeply respected for its commitment to quality, clients and customized solutions that drive measurable outcomes.
Similarly, Grant Thornton Spain is a significant, high-momentum member of the Grant Thornton network — with thousands of clients serviced by nearly 900 professionals across 10 locations. It has grown quickly thanks to its reputation for creative, forward-thinking solutions and deep sector expertise in areas such as financial services, mobility and energy.
Grant Thornton Belgium is an equally respected market leader rooted in globally strategic locations playing an integral role in the European Union. Its more than 250 professionals are deeply experienced in services related to cross-border mandates and mergers and acquisitions, as well as a range of audit, accounting, tax, legal and advisory needs.
In recent weeks, Grant Thornton Advisors has also announced transactions to enhance its advisory offerings. These include Auxis, a pioneer in outsourcing and business modernization services, and Stax, which specializes in commercial due diligence and value creation.
The entire Grant Thornton Advisors platform will continue to be part of the GTIL network, comprising member firms in more than 150 markets worldwide.
The transactions are all expected to close in the coming weeks.
