Sydney-based Grant Thornton Australia has completed its transaction to join the Chicago-based IPA 100 firm Grant Thornton Advisors’ (FY25 net revenue of $2.46 billion) multinational platform, adding 1,500 professionals and six offices to the cross-border organization.
The Australian firm, which reported annual revenue of about $282 million when the transaction was announced in April, expands Grant Thornton Advisors’ presence in the Asia-Pacific region. The platform already includes Grant Thornton New Zealand, which joined in late 2025 with more than 300 professionals.
As part of the transaction, Said Jahani, CEO of Grant Thornton Australia, has also been named CEO of the Asia-Pacific region for the multinational platform. He will continue leading the Australian firm and will join Grant Thornton Advisors’ executive committee, reporting to CEO Jim Peko.
In the newly created regional role, Jahani will oversee expansion of the platform’s Asia-Pacific footprint as well as client experience, quality, technology, delivery and service development.
“The Asia-Pacific region is one of the most dynamic growth markets in the world, and we are building a platform with the talent, technology and connectivity the region needs,” Jahani said.
The deal comes as Grant Thornton Advisors continues an expansion strategy backed by an investor group led by New Mountain Capital. In July, the firm announced an agreement to acquire CBIZ in a $5 billion transaction. Once that deal closes, the combined U.S. organization is expected to generate more than $5 billion in annual domestic revenue, while Grant Thornton Advisors’ multinational platform is expected to include more than 34,500 professionals across more than 20 countries and territories.
Grant Thornton Australia will remain part of the Grant Thornton International Limited network, whose member firms operate in more than 150 markets.
