Grant Thornton to Take CBIZ Private in $5 Billion Cash Deal

The Deal Terms

Grant Thornton Advisors is acquiring CBIZ in an all cash transaction valued at $5 billion. Shareholders will receive $55 per share, representing a 54% premium to the 30 day volume weighted average price. The CBIZ board unanimously approved the transaction and is recommending shareholders vote in favor.

Once the deal closes, CBIZ common stock will cease trading on the New York Stock Exchange and the company will become wholly owned by Grant Thornton. The transaction is expected to close in the fourth quarter of 2026, contingent on shareholder approval, regulatory sign off, and standard closing conditions.

New Mountain Capital, which led an investment in Grant Thornton Advisors back in May 2024, is providing $5.2 billion of committed financing to support the acquisition. This isn't a new relationship. New Mountain's earlier investment fueled Grant Thornton's growth strategy, and this deal extends that playbook.

What the Combined Entity Looks Like

The merger creates the fifth largest professional services, tax, and advisory provider in the United States. Grant Thornton's domestic revenue will exceed $5 billion annually once the deal closes. The global footprint expands significantly as well. The combined platform will span more than 20 countries and territories, generate nearly $7.5 billion in global revenue, and employ over 34,500 professionals.

Grant Thornton plans to separate CBIZ's Benefits and Insurance Services segment into a standalone entity backed by New Mountain Capital after closing. That's a meaningful structural decision. The benefits business has a different growth profile and margin structure than the core accounting and advisory operations. Spinning it off allows each business to pursue its own strategy with a dedicated capital base.

Go Shop Period and Competing Bids

The merger agreement includes a go shop provision that allows CBIZ and its advisors to actively solicit, consider, and negotiate alternative acquisition proposals from third parties. That window closes at 11:59 p.m. Eastern Time on August 27, 2026.

Before the shareholder vote, the CBIZ board retains the right to terminate the merger agreement to accept a superior proposal. Grant Thornton gets notice and negotiation rights if that happens, and CBIZ would owe a termination fee. There's no guarantee the go shop process produces a competing offer. CBIZ has said it won't disclose developments unless required by law or deemed appropriate.

For shareholders, the go shop provision creates a defined window to see if anyone is willing to pay more than $55 per share. Given the 54% premium to the 30 day VWAP, a topping bid would need to be aggressive to clear the bar.

CBIZ Operations and Recent Performance

CBIZ provides professional services to middle market businesses, including accounting, tax, advisory, benefits, and insurance services. The company has been consolidating in the space through acquisitions, including the completed BINDZ acquisition and a recent enterprise wide AI rollout.

For the first half of 2026, CBIZ reported revenue of $1.53 billion, up 0.6% year over year. Net income increased 4.1% to $171.4 million, and GAAP EPS rose 9.7% to $2.83. Adjusted diluted EPS came in at $3.44, up 3.6%. Operating cash flow and free cash flow each improved by roughly $100 million. The company repurchased about 2.5 million shares for approximately $70 million during the period, and net leverage stood at 3.4x, down 0.3x from a year earlier.

Due to the pending transaction, CBIZ cancelled its scheduled earnings call and withdrew its 2026 financial guidance. That's standard practice when a company enters into a definitive merger agreement. There's no point in guiding to numbers that may never materialize as a public company.

Strategic Rationale

Grant Thornton is making a scale play. The professional services industry rewards size through broader service offerings, deeper industry specialization, and the ability to invest in technology. The combined entity will have the resources to accelerate what the companies describe as AI enabled service delivery and industry specialization.

For CBIZ shareholders, the question is simple: take $55 in cash now or bet that either the company as a standalone achieves that value eventually, or a competing bidder emerges. The 54% premium to the 30 day VWAP is substantial. The board clearly thinks the bird in hand is the right call.

Private equity's involvement through New Mountain Capital reflects a broader trend in accounting and professional services M&A. These businesses generate steady cash flows, have sticky client relationships, and can benefit from operational improvements and technology investments that are easier to execute outside public market scrutiny.

What to Watch Next

The August 27 go shop deadline is the next key date. If no superior proposal emerges, the path to closing becomes more certain. Shareholders will then vote on the transaction, likely in the fall.

Regulatory review should be straightforward. This isn't a deal that creates antitrust concerns in a fragmented professional services market. The combination doesn't put the merged firm in a dominant position in any single market.

CBZ shares should trade close to the $55 deal price, with any discount reflecting time value and deal completion risk. If you see the spread widen materially, that would signal the market is pricing in some probability of the deal falling apart. For now, this looks like a clean transaction headed toward a Q4 close.
