Grant Thornton to Buy CBIZ for $5B as Q2 Earnings Beat

NEW YORK, July 29 —

Grant Thornton announced a $5 billion agreement to acquire CBIZ, Inc. on July 29, the same morning CBIZ reported second-quarter earnings per share that cleared analyst estimates while revenue fell short. By evening, at least two shareholder law firms had opened investigations into whether CBIZ investors are receiving adequate value. The company's proxy solicitation machinery was running before the day was out.

The Deal Math

The headline figure is $5 billion, but the more instructive number is $2.95 billion: CBIZ's market capitalization heading into the announcement. At $5 billion, Grant Thornton is paying roughly 70% above the company's recent standalone market value. CBZ shares gapped up on the combined news and now trade at $54.90, already 24% above the average analyst standalone price target of $44.40. When a stock trades that far above where analysts valued the business on its own merits, the deal premium is doing the lifting — and the size of that gap defines the terrain where the shareholder investigations will operate.

CBIZ carries trailing twelve-month revenue of $2.77 billion and $198 million in trailing free cash flow. At a 12.2x forward P/E, the current price implies the market has largely priced in deal completion. What it has not priced in is deal failure.

A Split Quarter to Sell Into

CBIZ's Q2 2026 results deserve their own reading, separate from the acquisition noise. EPS of $1.01 cleared the roughly $0.90 consensus by a wide margin. Revenue missed estimates, and the trailing year-over-year revenue growth rate sits at 1.3%. A company growing at that pace while beating per-share earnings is getting more from costs rather than expanding the top line. That dynamic matters for Grant Thornton as the acquirer: the platform generates real cash, but the organic growth story is modest. Trailing free cash flow of $198 million on $2.77 billion in revenue is the financial floor supporting the deal; whether Grant Thornton can accelerate the revenue line is the $5 billion bet.

The Fair-Price Argument

Halper Sadeh LLC and at least one other M&A class action firm announced investigations into whether CBIZ shareholders are receiving fair value in the proposed transaction, per news reports. The pattern is standard in sizable acquisitions: plaintiff firms open investigations within hours of announcement, and the large majority result in supplemental proxy disclosures rather than a revised deal price. The central question is whether the $5 billion price reflects what a fully competitive sale process would have produced. That answer lies in the board's account of how the deal came together, which the DEFA14A proxy materials filed with the SEC on July 29 are starting to reveal. The investigations add procedural friction to the timeline; they rarely add dollars to the consideration.

What the Approval Clock Looks Like

The deal requires both regulatory and shareholder approvals. Alongside the DEFA14A, CBIZ filed three additional SEC disclosures on July 29 — two 8-K filings and a Regulation FD press release — signaling active deal management on the disclosure front. The regulatory question for a combination of two sizable accounting and professional services platforms may draw antitrust scrutiny depending on service-line and geographic overlap. The shareholder investigations are a softer variable; most at this scale do not materially reset closing timelines. The checkpoints to watch are any regulatory review update and the date CBIZ sets for the shareholder vote, neither of which has been publicly disclosed in available filings.
