The proposed transaction prices CBIZ stock at $55 per share, representing a substantial premium over recent market valuations. When finalized, this combination will establish the fifth-largest professional services organization in the United States.
Grant Thornton Proposes $55-Per-Share All-Cash Transaction
Grant Thornton Advisors has entered into a definitive agreement to purchase CBIZ for a total enterprise value of $5 billion. The deal structure provides CBIZ stockholders with $55 in cash per common share held. This pricing reflects approximately a 54% premium compared to CBIZ’s volume-weighted average stock price over the preceding 30 trading days.
New Mountain Capital will contribute supplementary equity capital to support this acquisition, building on its partnership with Grant Thornton that began in May 2024. The private equity investor previously facilitated Grant Thornton’s domestic strategy expansion through a significant capital infusion. This fresh investment will finance both the transaction itself and future growth initiatives for the merged organization.
CBIZ’s board of directors has unanimously endorsed the merger agreement and will recommend stockholders vote in favor of the deal. Both parties anticipate completing the transaction in the fourth quarter of 2026. Final consummation depends on stockholder ratification, regulatory approvals, and satisfaction of customary closing requirements.
Merger Creates Expanded Professional Services Platform
This strategic combination will establish a United States-based professional services powerhouse generating over $5 billion in domestic annual revenue. The merged firm will rank as the nation’s fifth-largest provider of accounting, tax, and advisory solutions. Industry observers note this deal represents the sector’s most significant consolidation in over two and a half decades.
Following completion, the expanded multinational organization will maintain operations across more than 20 countries and territories globally. Total worldwide revenue is projected to approach $7.5 billion, supported by a workforce exceeding 34,500 professionals. Grant Thornton anticipates the enlarged footprint will enhance international service coordination and deepen specialized expertise offerings.
Grant Thornton intends to integrate its technology infrastructure throughout CBIZ’s existing client portfolio. The firm has committed $1 billion toward artificial intelligence and cutting-edge technology development. Consequently, the unified business projects enhanced service quality, increased workforce efficiency, and superior client experiences.
Insurance Division Planned for Separation
Grant Thornton’s acquisition plan includes spinning off CBIZ’s Benefits and Insurance Services division post-transaction. New Mountain Capital will provide backing for this unit to operate as a standalone enterprise. The separated business will concentrate on insurance products, retirement planning, payroll administration, and complementary services for its customer base.
Under the merger terms, CBIZ retains the right to pursue alternative acquisition proposals during a go-shop window concluding August 27, 2026. The company’s financial advisors may actively solicit, evaluate, and discuss competing transaction offers throughout this timeframe. CBIZ’s board maintains authority to accept a superior bid if one emerges that meets specified criteria.
Upon transaction completion, Grant Thornton will assume full ownership of CBIZ. CBIZ common stock will be delisted and cease trading on the New York Stock Exchange. Prior to closing, CBIZ will maintain its current operational framework and public company status.
