CBIZ acquisition history

CBIZ's largest-ever acquisition, roughly doubling the firm; brought Marcum's non-attest accounting and advisory business (with attest assets bought by affiliated CBIZ CPAs P.C.) to expand the breadth and depth of CBIZ's national professional-services portfolio. ~$2.3 billion aggregate consideration (~$1.1B cash + ~14.4M CBIZ shares); $1,997.8M total consideration recognized under ASC 805 ($1,063.0M cash + $934.7M stock, 13.6M shares).

The aggregate consideration to be paid by the Company in connection with the Transaction is approximately $2.3 billion, on a cash-free and debt-free basis... of which approximately $1.1 billion is expected to be paid in cash and the remainder is expected to be paid in approximately 14.4 million shares of the Company's Common Stock.

Acquired substantially all of the non-attest business of New York City accounting, tax and consulting firm Marks Paneth, expanding CBIZ's Financial Services practice in the New York metro market. ~$81.25 million cash at closing (plus earnout of up to $75.25 million in cash and CBIZ stock).

The initial purchase price for the Acquisition consisted of approximately $81.25 million in cash paid at closing, subject to a customary working capital adjustment.
