SUBSEQUENT EVENTS	SUBSEQUENT EVENTS Business Combinations: As previously disclosed, on July 30, 2024, we entered into an Agreement and Plan of Merger (the “Merger Agreement”) with Marcum LLP, a New York registered limited liability partnership (“Marcum”), Marcum Advisory Group LLC, a Delaware limited liability company and wholly owned subsidiary of Marcum (“MAG”), PMMS LLC, a Delaware limited liability company and a wholly owned subsidiary of the Company (“Merger Sub”), and Marcum Partners SPV LLC, a Delaware limited liability company (the “Owner Representative”). Under the terms of the Merger Agreement, at the closing, Merger Sub merged with and into MAG, with MAG continuing as the surviving entity and as a wholly owned subsidiary of the Company (the “Merger”). Prior to the closing of the Merger, Marcum contributed substantially all of its non-attest business assets to MAG, subject to certain exclusions, and MAG assumed certain Marcum liabilities. In a separate transaction, CBIZ CPAs P.C., previously known as Mayer Hoffman McCann P.C., a national independent certified public accounting firm with which the Company has an existing Administrative Services Agreement, purchased from Marcum substantially all of Marcum’s attest business assets, subject to certain exclusions ("Attest Purchase"). The Merger and the transactions contemplated by the Merger Agreement are referred to herein as the “Transaction.” On November 1, 2024, the Transaction was completed. At closing, we paid $637.6 million in cash as consideration to Marcum partners (including escrowed amounts) and an additional $425.5 million in cash to satisfy certain obligations of Marcum and for certain other specified closing payments as provided by the Merger Agreement. The cash portion of the purchase price paid to Marcum partners is subject to customary post-closing adjustments and escrow arrangements. In addition to the cash consideration, we will issue a total of 14,260,645 shares of our common stock (the “Shares”) to Marcum partners. The Shares will be delivered as follows: (i) 713,032 Shares will be subject to continued service requirements and, subject to satisfaction of those requirements, be delivered on the fourth anniversary of the closing; (ii) 2,852,129 Shares will be delivered on January 2, 2025; and (iii) the remaining 10,695,484 Shares will be delivered in 36 monthly installments commencing on January 2, 2025. We have yet to finalize the purchase price allocation for the Transaction, and are in the process of evaluating the effect that the Transaction will have on our consolidated financial statements. Amended and Restated Credit Facilities On November 1, 2024, the Company and CBIZ Operations, Inc., a wholly owned subsidiary of the Company, as the borrower (“CBIZ Operations”), Bank of America, N.A., as administrative agent, and the other financial institutions party thereto entered into an amended and restated credit agreement (the “2024 Credit Facilities”) providing for $2.0 billion in senior secured credit facilities, consisting of a $1.4 billion term loan (the “Term Loan”) and $600.0 million revolving credit facility (the “Revolving Credit Facility”). The 2024 Credit Facilities amend and restate the 2022 credit facility. The proceeds of the Term Loan were used to pay the cash consideration and make certain other payments in connection with the closing of the Transaction and to repay outstanding amounts under the 2022 credit facility. The 2024 Credit Facilities mature on November 1, 2029. The Term Loan provides for scheduled annual principal amortization payments of 5% in the first two years following closing, 7.5% annually in the third and fourth year following closing and 10% in the fifth year following closing, with the balance due at maturity. The commitments under the 2024 Credit Facilities may be increased in the form of incremental term facilities and/or increased commitments under the Revolving Credit Facility in an aggregate principal amount of up to the sum of (a) the greater of (i) $465.0 million and (ii) 100% of EBITDA, plus (b) an unlimited amount, so long as Total Net Leverage Ratio (“TNLR”) is no more than the lesser of 3.50 to 1.00 and TNLR at the closing after giving pro forma effect to the Transaction. The Company may elect an interest rate for the Term Loan and the Revolving Credit Facility based on the Base Rate or Term SOFR, plus an applicable spread. The Base Rate option is the highest of: (i) the Bank of America prime rate; (ii) the federal funds rate plus 0.50%; or (iii) Term SOFR plus 1.0%. Term SOFR is the forward-looking term rate based on the secured overnight financing rate that is published by CME Group Benchmark Administration Limited (or a successor administrator of such rate) plus a 0.10% SOFR Adjustment. The applicable spreads under the 2024 Credit Facilities will be 0.375% to 1.50% and 1.375% to 2.50% above the Base Rate and Term SOFR, respectively. The 2024 Credit Facilities include a financial covenant requiring that TNLR not exceed 5.00 to 1.00 initially, stepping down in increments to 3.75 to 1.00 during and after the seventh fiscal quarter after the closing (with a limited ability to temporarily increase in connection with material acquisitions commencing in the sixth fiscal quarter after the closing). The 2024 Credit Facilities also require a Minimum Consolidated Interest Coverage Ratio of 3.00 to 1.00 and affirmative and negative covenants that are in each case generally similar to those contained in the 2022 credit facility, but with increases to certain baskets and caps and certain other exceptions. The 2024 Credit Facilities are guaranteed by the Company and each of its domestic subsidiaries, subject to certain exceptions (the “Guarantors”), and are secured by substantially all assets of the Company, CBIZ Operations and the other Guarantors. As of November 1, 2024, the balance outstanding under the 2024 Credit Facilities was $1,465.5 million.
