Steve Tennant appointed to EMEA leadership role of Grant Thornton Advisors expanded multinational platform
Proven leader will become CEO for Europe, the Middle East and Africa
CHICAGO, Dublin, IRELAND, October 16, 2025 — Steve Tennant has been appointed CEO for Europe, the Middle East and Africa (EMEA), leading the continued growth of the Grant Thornton Advisors multinational platform and guiding its firms across the region to deliver consistent exceptional service delivery to clients. Tennant will continue to lead Grant Thornton Ireland and serve as a member of the Executive Committee of Grant Thornton Advisors, reporting to Jim Peko, CEO of the Grant Thornton Advisors multinational platform.
In recent months, Grant Thornton has rapidly expanded its world-class, multinational platform across the Americas, Europe and the Middle East. To support this growth, the platform has established a new operating structure with regions in the Americas and EMEA. Under this structure, Peko will serve in a dual role as CEO of the Americas.
As CEO of EMEA, Tennant will drive growth, deepening cross-border capabilities to provide market-leading, multi-jurisdictional support to deliver even greater value for clients and unlock opportunities for its people.
Tennant’s appointment is effective immediately and reflects his proven leadership in innovation, sustainability and client-centric growth as managing partner of Grant Thornton Ireland, a role he has held since January 2024.
Since its inception in January 2025, the Grant Thornton Advisors multinational platform has expanded by conducting transactions with a growing number of professional services firms across both the Americas and EMEA, including, most recently, France, Spain and Belgium, creating the need for a new operating structure.
“Steve’s appointment as EMEA CEO will help us continue to build and expand upon a unified, multinational platform that will deliver a singular client experience,” said Peko. “We’re not only expanding our footprint but also deepening our commitment to a culture that empowers our people and elevates the way we support our clients.”
“The rapid expansion of our multinational platform in the first half of this year reflects the evolving needs of clients and the changing landscape for professional services,” said Tennant. “I’m looking forward to leading our EMEA firms to further enhance collaboration across borders and build innovative capabilities and opportunities that benefit our people and deliver quality and excellence to our clients, wherever they are located.”
The Grant Thornton Advisors platform offers clients seamless cross-border advisory and tax services, supported by independent audit and assurance practices — backed by significant investment in technology, talent, and quality.
The platform is supported by an investor group led by New Mountain Capital, a growth-oriented investment firm with approximately $55 billion in assets under management.
It remains part of the Grant Thornton International Limited network, which spans over 150 markets globally.
