Item 1.01. Entry into a Material Definitive Agreement.

On July 28, 2026, CBIZ, Inc., a Delaware corporation (the “Company” or “CBIZ”), entered into an Agreement and Plan of Merger (the “Merger Agreement”), by and among the Company, Viking ParentCo, Inc., a Delaware corporation (“Parent”), and Viking MergerCo, Inc., a Delaware corporation and a direct wholly owned subsidiary of Parent (“Merger Sub”), pursuant to which, upon the terms and subject to the conditions set forth therein, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving the Merger as a direct wholly owned subsidiary of Parent. Capitalized terms used herein but not otherwise defined have the meaning set forth in the Merger Agreement.

The board of directors of the Company (the “Board”) has unanimously approved and declared advisable the Merger Agreement and the consummation of the transactions contemplated by the Merger Agreement, including the Merger, upon the terms and subject to the conditions set forth in the Merger Agreement and determined that the Merger is fair to, and in the best interests of, the Company and its stockholders. The Board has also resolved to recommend to the Company’s stockholders that the Company’s stockholders vote to adopt the Merger Agreement.

The Merger

Pursuant to the Merger Agreement, at the effective time of the Merger (the “Effective Time”), each share of common stock, par value $0.01 per share, of the Company (the “Shares” and each a “Share”) issued and outstanding immediately prior to the Effective Time ((a) other than Shares owned by (i) Parent or Merger Sub or any of their respective Subsidiaries, (ii) the Company as treasury stock, (iii) the Company’s direct or indirect wholly-owned subsidiaries (each such Share referred to in clauses (i), (ii) and (iii), an “Excluded Share” and, collectively, the “Excluded Shares”) and (iv) stockholders who have perfected and not withdrawn a demand for appraisal rights in accordance with Section 262 of the Delaware General Corporation Law (such stockholders, “Dissenting Stockholders”) and (b) including for the avoidance of doubt, Shares, other than the Performance Shares (as defined in the Marcum Agreement, the “Marcum Performance Shares”) issued immediately prior to the Effective Time in accordance with the terms of the Marcum Agreement), will be converted into the right to receive $55.00 per Share in cash, without interest thereon (the “Merger Consideration”).

Treatment of Equity Awards and Marcum Performance Shares

Immediately prior to the Effective Time (but contingent upon the Effective Time), each outstanding equity award will be treated as follows:

•

Each outstanding option to purchase Shares (a “Company Option”) that was granted under the 2019 CBIZ, Inc. Omnibus Incentive Plan (the “Company Stock Plan”) will be cancelled and converted automatically into the right to receive an aggregate amount in cash equal to the product of (a) the excess (if any) of the Merger Consideration over the applicable exercise price per Share underlying such Company Option and (b) the total number of Shares subject to such Company Option.

•

Each outstanding restricted stock unit granted under the Company Stock Plan that is subject solely to time-based vesting conditions (a “Company RSU”) that is vested as of immediately prior to the Effective Time and each Marcum Performance Share, in each case, will be cancelled and converted automatically into the right to receive the Merger Consideration.

•

Each Company RSU that is unvested as of immediately prior to the Effective Time will be cancelled and converted automatically into the right to receive (such right, a “Replacement RSU Award”) an

amount in cash equal to the Merger Consideration, which Replacement RSU Award will vest and become payable, subject to compliance with Section 409A of the United States Internal Revenue Code of 1986, as amended (the “Code”) and the holder’s continued employment with the Parent or its Affiliates, including the Surviving Corporation (subject to certain termination protections set forth below), on the same vesting schedule as the corresponding Company RSU would have vested pursuant to the terms thereof; provided that such Replacement RSU Award will vest in full upon the holder’s (a) termination without Cause, (b) death, (c) termination due to Disability, (d) termination due to Normal Retirement, or (e) resignation for Good Reason.

•

Each outstanding performance share unit granted under the Company Stock Plan that is subject to performance-based vesting conditions (a “Company PSU”) that is vested immediately prior to the Effective Time will be cancelled and converted automatically into the right to receive an amount in cash equal to the product of (i) the Merger Consideration and (ii) the number of Shares issuable in settlement of such vested Company PSU.

•

Each Company PSU that is unvested as of immediately prior to the Effective Time will be cancelled and converted automatically into the right to receive (such right, a “Replacement PSU Award”) an amount in cash equal to the product of (a) the Merger Consideration and (b) the number of Shares issuable in settlement of such award of Company PSUs, determined based on the achievement of target performance, which Replacement PSU Award will vest and become payable, subject to compliance with Section 409A of the Code and the holder’s continued employment with the Parent or its Affiliates, including the Surviving Corporation (subject to certain termination protections set forth below), on the last day of the performance period applicable to such corresponding Company PSU; provided that such Replacement PSU Award will vest in full upon the holder’s (a) termination without Cause, (b) death, (c) termination due to Disability, (d) termination due to Normal Retirement, or (e) resignation for Good Reason.

•

Each outstanding unit (a “Company Unit”) granted under the CBIZ Equity Aligned Cash Bonus Plan (the “EACB”) that is vested as of immediately prior to the Effective Time will be cancelled and converted automatically into the right to receive the Merger Consideration.

•

Each Company Unit that is unvested as of immediately prior to the Effective Time will be assumed by Parent (the “Assumed Units”) and continue to vest, subject to the holder’s continued employment with the Parent or its Affiliates, including the Surviving Corporation (subject to certain termination protections set forth below), in accordance with the terms of the EACB and the award agreement governing such Company Unit; provided that such Assumed Unit will vest in full upon the holder’s (a) termination without Cause, (b) death, (c) termination due to Disability, (d) termination due to Normal Retirement, or (e) resignation for Good Reason. Parent will pay (or cause the Surviving Corporation to pay) an amount in cash equal to the Merger Consideration in respect of each Assumed Unit that becomes vested.

•

Each outstanding share of restricted stock granted under the Company Stock Plan (a “Company Restricted Stock” award) that is (i) vested as of immediately prior to the Effective Time or (ii) held by any non-employee director of the Company will be cancelled and converted automatically into the right to receive the Merger Consideration.

•

Each share of Company Restricted Stock that is unvested as of immediately prior to the Effective Time will be cancelled and converted automatically into the right to receive (such right, a “Replacement Restricted Stock Award”) an amount in cash equal to the Merger Consideration,

which Replacement Restricted Stock Award will vest and become payable, subject to the holder’s continued employment with the Parent or its Affiliates, including the Surviving Corporation (subject to certain termination protections set forth below), on the same vesting schedule as the corresponding share of Company Restricted Stock; provided that such Replacement Restricted Stock Award will vest in full upon the holder’s (a) termination without Cause, (b) death, (c) termination due to Disability, (d) termination due to Normal Retirement, or (e) resignation for Good Reason.

•

Prior to the Effective Time, the CBIZ, Inc. Employee Stock Purchase Plan will be terminated.

Representations and Warranties

The Merger Agreement contains customary representations and warranties of the Company, with respect to, among other things, (i) organization, good standing and qualifications, (ii) capital structure, (iii) authorization to enter into the Merger Agreement, (iv) consents and approvals, (v) financial statements, (vi) absence of changes, (vii) litigation, (viii) undisclosed liabilities, (ix) employee benefits, (x) labor matters, (xi) compliance with laws and licenses, (xii) material contracts, (xiii) takeover statutes, (xiv) environmental matters, (xv) taxes, (xvi) intellectual property, (xvii) data privacy and artificial intelligence, (xviii) insurance, (xix) real property, (xx) affiliate transactions, (xxi) brokers, (xxii) opinion of financial advisor, (xxiii) broker-dealer matters, (xxiv) investment adviser matters, (xxv) compliance with insurance regulatory requirements, (xxvi) fiduciary assets and (xxvii) top clients, vendors and carriers. The Merger Agreement also includes certain materiality and knowledge qualified representations and warranties of the Company regarding the CPA Firms. The Merger Agreement also contains customary representations and warranties of Parent and Merger Sub with respect to, among other things, (i) entity organization, good standing and qualification, (ii) ownership, (iii) authorization to enter into the Merger Agreement, (iv) consents and approvals, (v) litigation, (vi) brokers, (vii) financing ability, (viii) the Limited Guarantee and (ix) solvency. The representations and warranties of the parties contained in the Merger Agreement will terminate and be of no further force and effect as of the closing of the transactions contemplated by the Merger Agreement. The representations and warranties made by the Company are qualified by disclosures made in disclosure schedules and its Securities and Exchange Commission (“SEC”) filings made of or after the Applicable Date and prior to the one calendar day prior to the date of this Agreement.

Covenants

The Merger Agreement contains covenants of the parties customary for a transaction of this type, including, among other things, covenants not to solicit alternative transactions during certain periods or to provide information or enter into discussions in connection with alternative transactions, subject to certain exceptions described below and to allow the Board to exercise its fiduciary duties in accordance with the Merger Agreement.

During the period beginning on the date of the Merger Agreement and continuing until 11:59 p.m. Eastern Time on August 27, 2026 (the “Go-Shop Period”), the Company and its representatives may solicit, initiate, knowingly encourage or knowingly facilitate any alternative acquisition proposal from third parties, participate in discussions and negotiations with such third parties regarding any acquisition proposal or provide nonpublic information to any persons related to any acquisition proposal (pursuant to a confidentiality agreement with each such person which complies with the terms of the Merger Agreement). Following expiration of the Go-Shop Period, the Company will be subject to customary “no-shop” restrictions on its ability to solicit, initiate, knowingly encourage or knowingly facilitate any alternative acquisition proposals from third parties, participate in discussions or negotiations with such third parties regarding such alternative acquisition proposals or provide nonpublic information to such third parties.

However, subject to the terms and conditions of the Merger Agreement, the Company may, until 15 days after the end of the Go-Shop Period, continue solicitation of, or discussions or negotiations with, third parties from whom a bona fide written acquisition proposal was received during the Go-Shop Period that the Board determines in good faith prior to the No-Shop Period Start Date, after consultation with its outside legal counsel and financial advisor, constitutes or would reasonably be expected to lead to a Superior Proposal and that the failure to evaluate such alternative acquisition proposal would be inconsistent with the Company directors’ fiduciary duties under applicable law (each such third party, an “Excluded Party”). In addition, the Company has agreed that, subject to certain exceptions, the Board will not withdraw its recommendation that the Company’s stockholders vote to adopt the Merger Agreement and approve the Merger.

Conditions to Closing

The parties’ respective obligations to consummate the Merger are subject to the satisfaction or waiver of customary conditions set forth in the Merger Agreement, including, among others: (i) the adoption of the Merger Agreement by the holders of a majority of the outstanding Shares, (ii) the expiration of the waiting period applicable to the consummation of the Merger under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended, (iii) the absence of any law or governmental order from any governmental entity of competent jurisdiction prohibiting the Merger, (iv) no Company Material Adverse Effect having occurred since the signing of the Merger Agreement and (v) certain other customary conditions relating to the parties’ representations and warranties in the Merger Agreement and the performance of their respective obligations, provided, that notwithstanding satisfaction of the closing conditions, Parent and Merger Sub will not be required to effect the Closing until the earlier of (i) a Business Day during the Marketing Period specified by Parent on no less than two Business Days’ prior written notice and (ii) the third Business Day following the final day of the Marketing Period.

Termination

The Merger Agreement contains certain customary termination rights for the Company and Parent, including (i) the right of the Company to terminate the Merger Agreement to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal, subject to specified limitations and requirements, and (ii) the right of Parent to terminate the Merger Agreement if the Board changes its recommendation that the Company’s stockholders vote to adopt the Merger Agreement and approve the Merger as described in the Merger Agreement. In addition to the foregoing termination rights and certain other termination rights set forth in the Merger Agreement, and subject to certain limitations, either party may terminate the Merger Agreement if the Merger is not consummated by July 28, 2027 (the “Termination Date”). The Company additionally has the ability to terminate the Merger Agreement if all of Parent’s and Merger Sub’s conditions to closing have been and continue to be satisfied or waived, Parent fails to consummate the Merger on the date on which the Closing should have occurred, the Company has irrevocably confirmed in writing to Parent that all conditions to the Closing have been satisfied or waived and the Company is prepared to consummate the Closing on the date of such written notice and throughout the subsequent three (3) business day period and Parent fails to consummate the Merger within three (3) business days following receipt of such written notice.

Upon termination of the Merger Agreement if (i) Parent terminates the Merger Agreement because the Board has changed its recommendation that the Company’s stockholders vote in favor of the Merger, (ii) (A) Parent or Company terminates the Merger Agreement following the Termination Date and no stockholder approval has been received at such time, or for failure to obtain stockholder approval for the transaction, or Parent terminates the Merger Agreement due to the Company’s uncured breach of the Merger Agreement, (B) prior to such termination, an acquisition proposal for a majority sale was made to

the Company or publicly proposed and announced and (C) concurrently or within twelve (12) months after the date of such termination the Company enters into a definitive agreement with respect to, or consummates, any acquisition proposal or (iii) the Company terminates the Merger Agreement to enter into an Alternative Acquisition Agreement with respect to a Superior Proposal, the Company will be required to pay to Parent, within two (2) business days after such termination in the case of clause (i), concurrently with the entry into such definitive agreement or such closing in the case of clause (ii) or concurrently with such termination in the case of clause (iii), a termination fee of $107,500,000 (the “Company Termination Fee”); provided, that if the Company terminates the Merger Agreement pursuant to clause (iii) during the Go-Shop Period or to enter into an Alternative Acquisition Agreement with an Excluded Party, such fee shall instead be equal to $49,600,000.

Parent will be required to pay or cause to be paid to the Company a termination fee of $198,400,000 (the “Parent Termination Fee”), (i) if the Company terminates the Merger Agreement because of either (A) a failure of Parent to consummate the Merger when required to or (B) Parent’s or Merger Sub’s uncured breach of the Merger Agreement such that certain of the Company’s conditions to the Closing would not be satisfied, or (ii) the Parent terminates the Merger Agreement because the Termination Date has passed at a time when the Company could have terminated the Merger Agreement based on the circumstances in clause (i) .

Limited Guarantee

Concurrently with the execution of the Merger Agreement, Grant Thornton Advisors LLC (the “Guarantor”) entered into a limited guarantee (the “Limited Guarantee”) with the Company, pursuant to which the Guarantor has provided a limited guarantee with respect to the payment of the Parent Termination Fee, as well as certain reimbursement obligations that may be owed by Parent pursuant to the Merger Agreement, in each case subject to the terms of the Merger Agreement and of such Limited Guarantee.

Financing Letters

Concurrently with the execution of the Merger Agreement, pursuant to the terms of equity and debt commitment letters entered into by Parent and/or Affiliates thereof, New Mountain Partners VII, L.P., New Mountain Partners VII Luxembourg, SCSp and certain additional third-party financing sources have committed to provide, subject to the terms and conditions set forth therein, financing to Parent in an aggregate amount of $5.2 billion to fund Parent’s payment obligations in respect of the transactions contemplated by the Merger Agreement and pay related fees and expenses. The funding of all such commitments is subject to the satisfaction of customary closing conditions.

The foregoing description of the Merger Agreement and the Merger does not purport to be complete, and is subject to and is qualified in its entirety by references to the full text of the Merger Agreement and any related agreements. The Merger Agreement contains representations, warranties and covenants that the respective parties made to each other as of the date of such agreement or other specific dates. The assertions embodied in those representations, warranties and covenants were made for purposes of the contract among the respective parties and are subject to important qualifications and limitations agreed to by the parties in connection with negotiating such agreement. The Merger Agreement has been attached to provide investors with information regarding its terms. It is not intended to provide any other factual information about the Company, Parent or any other party to the Merger Agreement or any related agreement. In particular, the representations, warranties, covenants and agreements contained in the Merger Agreement, which were made only for purposes of such agreement and as of specific dates, were for the benefit of the parties to the Merger Agreement, may be subject to limitations agreed upon by the contracting parties (including being qualified by confidential disclosures made for the purposes of allocating contractual risk between the parties

to the Merger Agreement instead of establishing these matters as facts) and may be subject to standards of materiality applicable to the contracting parties that differ from those applicable to investors and security holders. Investors and security holders are not third-party beneficiaries under the Merger Agreement (except, following the Effective Time, with respect to the right of holders of Company equity awards to receive the consideration provided for such equity awards pursuant to the Merger Agreement) and should not rely on the representations, warranties, covenants and agreements, or any descriptions thereof, as characterizations of the actual state of facts or condition of any party to the Merger Agreement. Moreover, information concerning the subject matter of the representations and warranties may change after the date of the Merger Agreement, which subsequent information may or may not be fully reflected in the Company’s public disclosures.

A copy of the Merger Agreement is filed with this Current Report on Form 8-K as Exhibit 2.1 and is incorporated herein by reference, and the foregoing description of the Merger Agreement is qualified in its entirety by reference thereto.

Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

In connection with the entry into the Merger Agreement, on July 28, 2026, the Board adopted the CBIZ, Inc. Change in Control Severance Plan (the “CIC Severance Plan”), which generally provides eligible employees of the Company, including the Company’s named executive officers (the “NEOs”), with severance payments in the event of a termination of employment during the period commencing on the earlier of (i) the public announcement by the Company of a transaction that results in a change in control of the Company and (ii) the entry by the Company into a definitive agreement that results in a change in control of the Company, and ending two-years following the consummation of a change in control of the Company. Under the CIC Severance Plan, upon a termination of a participant’s employment by the Company without “Cause” or due to the participant’s resignation for “Good Reason” (as each term is defined in the CIC Severance Plan), the participant is entitled to receive, in accordance with the terms of the CIC Severance Plan, a cash payment in the amount equal to the sum of (i) a multiple of the participant’s annual compensation (inclusive of base salary and target annual bonus), which multiple ranges from 0.5x – 3x (based on position, with the Company’s CEO eligible to receive 3x, and all other NEOs eligible to receive 2x), (ii) the participant’s prorated annual bonus for the year of termination at the target level of performance, and (iii) the monthly cost of the participant’s premiums for coverage under the Company’s group health plan for a period ranging from 6 to 36 months (based on position). Severance payments and benefits under the CIC Severance Plan are contingent upon the eligible employee’s execution of a general release of claims.

On July 28, 2026, the Board adopted a transaction bonus program and a retention program for certain eligible employees. Pursuant to the retention bonus program eligible employees will receive retention bonuses. 25% of the retention bonus is payable upon the consummation of a change in control (as defined in the CBIZ, Inc. Omnibus Incentive Plan) and 75% is payable on the date that is 6 months following the consummation of a change in control, subject generally to continued employment through the applicable retention date (with certain good leaver termination protections). The transaction bonuses will be paid shortly following the Company’s entry into the Merger Agreement. The Company’s NEO’s are eligible for the following amounts under the programs: Jerome P. Grisko, Jr. ($1,302,000); Brad Lakhia ($812,000); and Michael Kouzelos ($486,000).

A copy of the CIC Severance Plan is filed with this Current Report on Form 8-K as Exhibit 10.1 and is incorporated herein by reference, and the foregoing description of the CIC Severance Plan is qualified in its entirety by reference thereto.

Item 7.01 Regulation FD Disclosure.

On July 28, 2026, the Company and Parent issued a joint press release announcing that they have entered into the Merger Agreement. A copy of the press release is attached as Exhibit 99.1 to this Current Report on Form 8-K and is incorporated herein by reference.

These forward-looking statements are based on the Company’s and Parent’s current expectations with respect to the transactions contemplated by the Merger Agreement and are subject to risks and uncertainties, which may cause actual results to differ materially from the Company’s and Parents’s current expectations. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those indicated or anticipated by such forward-looking statements.
