The Deal That's Redefining the U.S. Professional Services Market
Grant Thornton Advisors announced on Wednesday, July 29, 2026, that it had entered into a definitive agreement to acquire CBIZ, Inc. (NYSE: CBZ) in an all-cash transaction with an enterprise value of $5 billion. This deal represents a significant milestone for Grant Thornton, which has been strategically positioning itself for growth. The acquisition is expected to position Grant Thornton as the fifth-largest provider of professional, tax, and advisory services in the U.S. The transaction is expected to close in the latter half of 2026, subject to customary closing conditions and regulatory approvals.
The acquisition underscores Grant Thornton’s ambitious growth strategy, fueled by New Mountain Capital’s investment. This private equity firm, which led a significant investment in Grant Thornton Advisors in May 2024, is set to provide additional equity to support the transaction, highlighting their confidence in the combined entity’s future prospects.
CBIZ Stock: A Rollercoaster Ride and a Premium Payout
CBIZ’s stock has been on a rollercoaster ride, with a 51% drop over the past year, reflecting broader market trends and internal challenges.

The acquisition comes at a critical time for CBIZ, which has recently disclosed material control weaknesses and made revisions to its Q1 2026 financials. These challenges, while concerning, did not deter Grant Thornton from pursuing the deal, indicating a long-term strategic vision.
In the midst of the CBIZ deal, the company has also outlined plans for a voluntary rescission offer on 48,1049 Employee Stock Purchase Plan (ESPP) shares, adding another layer of complexity to the transaction. This move is part of CBIZ’s efforts to address internal issues and streamline operations ahead of the acquisition.
