Grant Thornton Advisors completed its acquisition of CBIZ on November 2, 2026, in an all-cash transaction with an enterprise value of USD 5 billion, according to coverage from ad-hoc-news.de. The closing of the deal officially concluded CBIZ's public-market history, with its common stock ceasing trade on the New York Stock Exchange (NYSE).
Following the transaction, CBIZ has become a wholly owned subsidiary of Grant Thornton Advisors, shifting its operations into the broader Grant Thornton platform. Grant Thornton described the combined entity as the fifth-largest U.S. provider of professional services, tax, and advisory offerings.
Scale and Industry Footprint
The combined platform is projected to generate more than USD 7 billion in annual revenue while employing over 34,500 professionals across more than 25 countries and territories. The merger unites CBIZ's domestic industry knowledge and U.S. client relationships with Grant Thornton's global footprint and technology infrastructure. Prior to the sale, CBIZ provided accounting, tax, advisory, benefits, and insurance services across sectors including real estate, construction, and industrial products.
Business Carve-Out and Future Accounting Integration
As part of the structural shifts surrounding the acquisition, CBIZ's Benefits & Insurance Services segment was established as an independent business backed by private equity firm New Mountain Capital. This move separates the benefits and insurance operations from both the former CBIZ parent entity and Grant Thornton Advisors.
Meanwhile, a separate transaction between Grant Thornton LLP and CBIZ CPAs is anticipated to close later in 2026. Under the planned arrangement, CBIZ CPAs will operate as a separate licensed public accounting firm during a transition phase before its expected integration into Grant Thornton LLP.
The deal expands Grant Thornton's footprint across the U.S. market, where it competes against major accounting and advisory providers such as Deloitte, PwC, and RSM.
