Reference is made to the sign-on bonus payable to me pursuant to the offer letter dated January 26, 2026 in connection with the commencement of my employment with Cboe Services Company (the “Company”). I understand that upon completion of twelve (12) months of employment with the Company (the “Retention Period”), I will earn a one-time bonus in the amount of $627,200 (the “Sign-On Bonus”), less applicable tax withholdings. In exchange for the Company’s agreement to advance the Sign-On Bonus to me within thirty (30) days following the commencement of my employment, and for other good and valuable consideration, the adequacy, sufficiency and receipt of which are hereby acknowledged, I hereby understand and agree as follows:

1. The Sign-On Bonus will be earned by me only if I remain continuously employed with the Company through the Retention Period. The payment of the Sign-On Bonus to me prior to the completion of the Retention Period is an advance that will be subject to repayment as described below. I must be employed by the Company on the day the Sign-On Bonus is paid in order to receive it.

2. If I resign from my employment with the Company, or if the Company terminates my employment due to “cause”, as defined in the Cboe Global Markets, Inc. Amended and Restated Executive Severance Plan, at any time during the Retention Period, I will repay the gross amount of the Sign-On Bonus advanced to me by the Company.

3. I will repay any amount due from me under this Agreement within ninety (90) days following the termination of my employment with the Company. The Company may (without limitation of the Company’s rights to other remedies or methods of recovery permitted by law) offset against any amounts owed by the Company to me to the extent permitted by applicable law. The acceptance by the Company of partial or delinquent payments, or the failure of the Company to exercise any rights under this Agreement, shall not waive any of my obligations or the rights of the Company, modify this Agreement, or waive any other similar breach of this Agreement by me.

4. I will not be required to repay any portion of the Sign-On Bonus advanced to me if I remain employed with the Company for the full Retention Period or if the Company terminates my employment for reasons other than for “cause”, except as may be

required pursuant to any Company compensation recovery policies, including (i) the Company’s Executive Officer Incentive Compensation Clawback Policy (as amended from time to time, or any successor policy), (ii) the Company’s Supplemental Discretionary Clawback Policy (as amended from time to time, or any successor policy), (iii) any recoupment, clawback or similar requirements made applicable by law, regulation or listing standards to the Company from time to time (to the extent contemplated by such requirements), or (iv) as may be adopted by the Company to help facilitate the Corporation’s objectives, including, without limitation, related to eliminating or reducing fraud, misconduct, wrongdoing, or violations of law by an employee or similar considerations and, in each case, as may be amended from time to time (the “Policies”) with the provisions contained in such Policies deemed incorporated into this Agreement without my additional or separate consent.

6. This Agreement does not constitute, and may not be construed as, a commitment by the Company to employ me for any specific duration. My employment with the Company will be at will, which means that I may leave the Company, or the Company may terminate my employment, for any reason, at any time.

8. This Agreement represents my entire understanding with the Company, and supersedes all prior oral or written agreements or understandings, with respect to the advancement and repayment of the Sign-On Bonus. It may be changed only by a written agreement signed by me and the Company.

9. I may not assign any of my rights or obligations under this Agreement. This Agreement shall be binding upon and inure to the benefit of the Company’s successors and assigns. Without limiting the foregoing, the Company may assign its rights and delegate its duties hereunder in whole or in part to any affiliate of the Company or to any transferee of all or a portion of the assets or business to which my employment relates.
