Grant Thornton Advisors has agreed to acquire CBIZ in an all-cash transaction valued at $5 billion, creating the 5th largest professional services, tax, and advisory provider in the U.S. and closing the gap on the Big Four.
📊 Key Financial & Deal Metrics
- Transaction Value: $5 billion all-cash deal ($55.00/share), representing a 17.8% premium over CBIZ’s previous close.
- Combined Platform Revenue: Expected to exceed $7.5 billion in revenue across more than 20 countries and territories.
- Sponsor Backing: Supported by a new equity investment from New Mountain Capital in what marks the largest transaction in the accounting sector in over 25 years.
- Deal Timeline: Expected to close in Q4 2026, with a “go-shop” period open through August 27. Following closing, CBIZ’s benefits & insurance services segment will spin off into an independent entity.
💡 Industry Consolidation & Strategy
- Challenging the Big Four: Creates a formidable mid-tier powerhouse behind Deloitte, EY, KPMG, and PwC amid rapid industry consolidation (following the Baker Tilly-Moss Adams and Marcum deals).
- Middle-Market Reach: Combines Grant Thornton’s multinational advisory footprint with CBIZ’s deep U.S. middle-market presence.
💡 The Strategic Takeaway
Supported by private equity capital, the acquisition of CBIZ accelerates Grant Thornton’s scale, setting a new benchmark for consolidation in the professional services sector.
