Brazilian arm of Grant Thornton joins investor-backed multinational platform
The Brazilian arm of Grant Thornton has joined Grant Thornton Advisors, the company’s private equity-backed multinational platform.
With nearly 2,000 professionals and over $80 million in annual revenue, Grant Thornton is one of the largest accounting and consulting firms in Brazil.
The addition of Brazil marks Grant Thornton Advisors’ first expansion into South America and is one of the platform’s largest deals to date. This month, the group also welcomed the New Zealand and Poland member firms, following earlier additions in Europe (France, Spain, Belgium, Switzerland) and the Middle East (UAE), among others.
Today, Grant Thornton Advisors comprises 16 member firms with a combined workforce of more than 18,000 professionals.
“Welcoming Brazil is a major step forward in our mission to build a truly cross-border professional services platform,” said Jim Peko, CEO of Grant Thornton Advisors. “We’re bringing together talent, technology, and trust across firms and 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.”
Grant Thornton Advisors was launched at the start of this year following a tie-up between the US and Irish member firms of Grant Thornton, backed by New Mountain Capital, a leading US-based investor.
In addition to integrating member firms, Grant Thornton Advisors has also completed other acquisitions, including Stax – a strategy consulting firm specializing in commercial due diligence and value creation – and Auxis, which focuses on outsourcing and business modernization.
“Joining the Grant Thornton Advisors platform marks a transformative milestone for our firm, our clients and our professionals,” said Daniel Maranhão, CEO of Grant Thornton in Brazil.
“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. Financial terms have not been disclosed.
