Grant Thornton Advisors announces that Grant Thornton Australia is advancing plans to join its platform
CHICAGO and SYDNEY, April 27, 2026 – Grant Thornton Advisors LLC has announced that Grant Thornton Australia is advancing plans to join its multinational platform, a rapidly expanding group of nearly 20 aligned firms spanning the Americas, Europe, the Middle East and the Asia Pacific region.
For the Grant Thornton Advisors platform, the transaction would bring additional scale and momentum tied to the Australian firm’s annual revenues of USD $282M (AUD $392M), 1,500 employees and six offices. It would also benefit from Grant Thornton Australia’s market strength and reputation for quality.
The result: an even stronger ability to serve clients with integrated, multidisciplinary teams that coordinate seamlessly across borders — as well as added capacity to deliver innovative solutions backed by consistent, technology-enabled engagement teams that share a commitment to quality.
In addition, the transaction would significantly expand the Grant Thornton Advisors platform’s Asia Pacific presence, building on its footprint in New Zealand and opening new pathways for regional growth.
For Grant Thornton Australia, the proposed transaction is the result of an extensive strategic review, during which its board evaluated multiple pathways to advance the firm’s ambitious strategy. The transaction has been recommended by the board and would close later this year subject to shareholder partner approval and standard regulatory conditions.
It would accelerate Grant Thornton Australia’s growth strategy, expanding its access to world‑class AI and technology capabilities, while creating compelling career pathways for its next generation of partners and high‑performing professionals. Importantly, it would preserve the local market culture and agility that define Grant Thornton Australia.
Through the proposed deal, Grant Thornton Australia would continue to provide best-in-class advisory and tax services, and its audit practice would remain committed to independence and stringent governance — demonstrating a focus on the highest quality standards and adhering to all regulatory requirements.
Grant Thornton Australia would continue to be part of the Grant Thornton International Limited network, which comprises member firms in more than 150 markets worldwide.
Jim Peko, CEO of Grant Thornton Advisors LLC and leader of its multinational platform: “Grant Thornton Australia is a standout firm — with strong momentum, exceptional leadership and a culture that has earned deep respect in its market. Its intention to join our platform reflects a shared ambition: to build something more connected, more capable and more forward-looking for our clients and for our people. Together, we can accelerate growth across the Asia Pacific region while strengthening how we serve clients seamlessly across borders. This is exactly the kind of partnership we seek as we continue to build a differentiated platform with scale and purpose.”
Said Jahani, CEO of Grant Thornton Australia: “This proposed transaction promises an exciting new chapter for our firm. Joining the Grant Thornton Advisors platform would give us accelerated access to emerging tech capabilities and growth capital, accelerating our ambition to build Australia’s most modern, internationally aligned professional services firm. It would both enhance our client offerings and deepen the opportunities we can provide for our team. This is about seizing the right growth lever, and we are incredibly excited for what lies ahead.”
