Grant Thornton advisers agree to acquire rival accountancy group CBIZ in a transaction valued at USD5 billion. The deal positions the combined company as the fifth-largest provider of advisory services in the United States, sitting just behind the Big Four firms in scale.
Under the terms of the agreement, CBIZ shareholders are set to receive USD55 in cash for each share they hold. That price represents a 54% premium over CBIZ’s average share price during the previous 30 trading days, giving investors a substantial short-term uplift. The offer still sits below CBIZ’s record share price of USD88.65, which the company reached last year during a stronger market phase. The deal is structured entirely in cash, signalling Grant Thornton’s confidence in the combined business’s earnings power.
Together, Grant Thornton and CBIZ are expected to operate across 20 countries and employ around 34,500 people, significantly expanding the advisory network’s geographic and sector reach. The merged organisation is projected to generate almost USD7.5 billion in annual revenue, putting clear distance between it and smaller mid-tier competitors.
Industry analysts highlight that this is the largest accounting-sector merger since Price Waterhouse combined with Coopers & Lybrand in 1998, a landmark that reshaped the global audit market.
Market observers note that while the combined firm looks set to rival parts of the Big Four in specific niches, leadership at Grant Thornton signals no ambition to formally join that grouping. The strategy focuses on building a strong alternative for clients that want scale, international coverage and complex advisory work without defaulting to the largest incumbents.
That positioning could intensify competition for audit, tax and consulting mandates in the United States, especially among mid-cap and upper mid-market companies.
