Sycomore Corporate Finance is pleased to share that Grant Thornton France has joined Grant Thornton Advisors, together with Grant Thornton Spain and Grant Thornton Belgium.
Grant Thornton France becomes part of a broader platform that also includes the recently announced acquisitions of 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, and the platform looks to continue selectively welcoming the highest quality, most collaborative firms across strategic markets.
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.
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 expected to close in the coming weeks, subject to customary works council consultations and regulatory approvals.

With our proven expertise and strategic location at the heart of European business, we’re confident this important milestone will drive innovation and accelerate long-term growth. »
Steve Tennant, managing partner at Grant Thornton Ireland, noted:
« Ireland was the first building block in Grant Thornton Advisors’ strategic multinational expansion, and we’ve seen firsthand the benefits of integrating our people, resources and client services into a unified platform. Adding France, Spain and Belgium builds on that momentum, creating an unmatched presence across the European Union and many other markets. »
Jim Peko, CEO of Grant Thornton Advisors LLC, added:
« Expanding the platform into France, Spain and Belgium is a defining chapter in our journey and represents a sea change in how our industry serves clients. We’re furthering our commitment to growth across services, industries and geographies. And we’re solidifying Grant Thornton as the platform of choice for talent and technology, underpinned by exceptional quality and our one-of-a-kind culture. We set out to build something bold and that’s exactly what we’re doing. »
Andre Moura and Nikhil Devulapalli, managing directors at New Mountain Capital, concluded:
« We couldn’t be more pleased to admit France, Spain and Belgium to the global unified platform. The visionary leadership of these firms embodies the best of Grant Thornton, and today’s news is yet another example of our commitment to invest in people, technology and expanded capabilities for the ultimate benefit of Grant Thornton’s clients. We’re just getting started. »
