Grant Thornton to buy CBIZ for $5bn, reshaping US mid-market accounting
Grant Thornton will acquire CBIZ for $5 billion in cash, valuing CBIZ at an enterprise value of $5bn and paying $55 per share, in the largest accounting-sector takeover in a generation. The deal creates a US revenue base exceeding $5bn and positions the combined firm as the largest audit and consulting group in the US outside the Big Four, with New Mountain Capital planning to spin off CBIZ’s non-accounting businesses after closing. The consolidation underscores ongoing private-equity–driven changes in the mid-market accounting sector.
