Grant Thornton Advisors to add Brazil to multinational platform
CHICAGO and SAO PAULO, November 11, 2025 – Grant Thornton Advisors LLC (Grant Thornton Advisors) today announced that it is adding Grant Thornton Brazil to its multinational platform.
The transaction will extend the platform’s reach into Latin America’s biggest market and follows on the heels of similar deals that will add Grant Thornton New Zealand and Grant Thornton Poland to the platform. The additions will expand the platform’s integrated cross-border footprint to include 16 firms spanning 20 time zones.
Grant Thornton Brazil is a top five firm in its market and has demonstrated rapid recent growth. With almost 2,000 professionals and US$80+ million in annual revenue, the firm offers audit and tax services, complemented by a range of innovative advisory services, including a thriving business-process-optimization offering.
Grant Thornton Advisors launched its platform earlier this year with the support of an investor group led by New Mountain Capital — and is bringing high-performing firms across the Americas, Europe, the Middle East and the Asia Pacific region into an integrated advisory and tax practice, complemented by independent audit practices.
The platform currently includes Grant Thornton firms in the US, Ireland, France, the United Arab Emirates, Belgium, the Netherlands, Switzerland, Liechtenstein, the Channel Islands and the Cayman Islands. Additionally, it has announced transactions with Grant Thornton firms in Spain, Luxembourg, New Zealand and Poland, which it anticipates closing in the coming weeks. Further, it has added top firms serving strategic markets and industries, including Auxis, a pioneer in outsourcing and business modernization — and Stax, a specialist in commercial due diligence and value creation.
“Welcoming Brazil — right after New Zealand and Poland — is a leap forward in our mission to build a truly cross-border professional services platform,” said Jim Peko, CEO of Grant Thornton Advisors LLC and CEO of the Americas. “We’re combining talent, technology and trust across 16 firms and 20 time zones to deliver seamless, high-impact solutions. Brazil’s scale, momentum and strategic relevance make it a cornerstone of this vision, and we’re honored to have them on board.”
According to Daniel Maranhão, CEO of Grant Thornton Brazil: “Joining the Grant Thornton Advisors platform marks a transformative milestone for our firm, our clients and our professionals. Brazil is a dynamic, fast-evolving market and this move gives us the multinational reach, resources and strategic alignment to scale our impact. We’re proud to represent Latin America on a platform that spans much of the globe. And we’re excited to help shape the future of cross-border professional services.”
The transaction is expected to close later this year.
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.
