16 May 2025
Grant Thornton Advisors LLC’s multinational platform grows to include Grant Thornton Netherlands
Chicago and Amsterdam, May 16, 2025— Grant Thornton Advisors LLC (Grant Thornton Advisors) today announced that Grant Thornton Netherlands is joining the multinational platform it established earlier this year with Grant Thornton Ireland.
The platform is backed by an investor group led by New Mountain Capital, a growth-oriented investment firm with approximately $55 billion in assets under management. Last month, three Grant Thornton firms in Europe, the Middle East and the Americas closed or signed agreements to join the platform.
Joining the platform will allow Grant Thornton Netherlands to offer enhanced services to new and existing clients across markets, underpinned by investments in quality, innovation, and seamless client-centric delivery.
Grant Thornton Netherlands’s team of almost 800 professionals across eight Dutch offices will join the platform’s nearly 13,000 team members in almost 60 offices. The expanded platform remains part of the Grant Thornton International Limited network, which comprises member firms in more than 150 markets worldwide.
Marcel Blöte, CEO of Grant Thornton Netherlands, will remain in his current position as head of that geography. The audit practice of Grant Thornton Netherlands will operate independently under an alternative practice structure.
“By uniting with preeminent high-growth firms such as Grant Thornton Netherlands, we’ve established a world-class service provider platform spanning multinational markets,” said Jim Peko, CEO of Grant Thornton Advisors. “We will continue to solidify our standing as the industry’s destination of choice for clients and team members alike, providing a singular experience focused on quality and unparalleled service delivery.”
“We welcome Grant Thornton Netherlands to our expanded platform,” said Steve Tennant, managing partner of Grant Thornton in Ireland, who leads international M&A on behalf of Grant Thornton Advisors. “The Dutch firm brings complementary ambition and talent as we look to extend our capabilities, services and geographic reach to benefit our clients and our people.”
According to Netherlands’s Blöte: “Joining forces with Grant Thornton Advisors empowers us to deliver enhanced value for clients as a diversified platform poised for growth and expansion. We’ll be able to offer our people extremely attractive paths for career development, while maintaining our hallmark entrepreneurial culture and commitment to quality. Collectively, we will ensure our status as a top 10 firm in our market well into the future — one that can flexibly respond to a dynamic market and changing regulations.”
“We’re bringing the highest quality and fastest growing firms together into one truly integrated global platform,” said Andre Moura, managing director, New Mountain Capital. “Grant Thornton Netherlands is a perfect example of this — delivering the quality, expertise and industry specialization integral to the world-class client experience we’re creating.”
The transaction is expected to close later this year, subject to regulatory approvals and other standard closing conditions.
