We have not independently verified any of the data from third-party sources nor have we ascertained the underlying economic assumptions relied upon therein. Statements as to our market position are based on the most currently available market data. While we are not aware of any misstatements regarding industry data presented herein, our estimates involve risks and uncertainties and are subject to change based on various factors.

FORWARD-LOOKING STATEMENTS

This Quarterly Report on Form 10-Q contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 that involve a number of risks and uncertainties. You can identify these statements by forward-looking words such as “may,” “might,” “should,” “expect,” “plan,” “anticipate,” “believe,” “estimate,” “predict,” “potential” or “continue,” and the negative of these terms and other comparable terminology. All statements that reflect our expectations, assumptions or projections about the future other than statements of historical fact are forward-looking statements, including statements in “Management’s Discussion and Analysis of Financial Condition and Results of Operations”. These forward-looking statements, which are subject to known and unknown risks, uncertainties and assumptions about us, may include projections of our future financial performance based on our growth strategies and anticipated trends in our business. These statements are only predictions based on our current expectations and projections about future events. There are important factors that could cause our actual results, level of activity, performance or achievements to differ materially from those expressed or implied by the forward-looking statements. In particular, you should consider the risks and uncertainties described under “Risk Factors” in this Quarterly Report and other filings with the SEC.

While we believe we have identified material risks, these risks and uncertainties are not exhaustive. Moreover, we operate in a very competitive and rapidly changing environment. New risks and uncertainties emerge from time to time, and it is not possible to predict all risks and uncertainties, nor can we assess the impact of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements.

Some factors that could cause actual results to differ include:

● the loss of our right to exclusively list and trade certain index options and futures products;

● economic, political and market conditions;

● compliance with legal and regulatory obligations;

● price competition and consolidation in our industry;

● decreases in trading or clearing volumes, market data fees or a shift in the mix of products traded on our exchanges;

● legislative or regulatory changes or changes in tax regimes;

● our ability to protect our systems and communication networks from security vulnerabilities and breaches;

● our ability to attract and retain skilled management and other personnel, including compensation inflation;

● increasing competition by foreign and domestic entities;

● our dependence on and exposure to risk from third parties;

● global expansion of operations;

● factors that impact the quality and integrity of our indices;

● our ability to manage our growth and strategic acquisitions or alliances effectively;

● our ability to operate our business without violating the intellectual property rights of others and the costs associated with protecting our intellectual property rights;

● our ability to minimize the risks, including our credit, counterparty, investment, and default risks, associated with operating a European clearinghouse;

● our ability to accommodate trading and clearing volume and transaction traffic, including significant increases, without failure or degradation of performance of our systems;

● misconduct by those who use our markets or our products or for whom we clear transactions;

● challenges to our use of open source software code;

● our ability to meet our compliance obligations, including managing potential conflicts between our regulatory responsibilities and our for-profit status;

● our ability to maintain BIDS Trading as an independently managed and operated trading venue, separate from and not integrated with our registered national securities exchanges;

● damage to our reputation;

● the ability of our compliance and risk management methods to effectively monitor and manage our risks;

● restrictions imposed by our debt obligations and our ability to make payments on or refinance our debt obligations;

● our ability to maintain an investment grade credit rating;

● impairment of our goodwill, long-lived assets, investments or intangible assets;

● the impacts of pandemics;

● the accuracy of our estimates and expectations;

6

● litigation risks and other liabilities; and

● operating a digital asset business, and clearinghouse, including the expected benefits of our Cboe Digital acquisition, cybercrime, changes in digital asset regulation, losses due to digital asset custody, and fluctuations in digital asset prices.

For a detailed discussion of these and other factors that might affect our performance, see Part II, Item 1A of this Report. We do not undertake, and expressly disclaim, any duty to update any forward-looking statement whether as a result of new information, future events or otherwise, except as required by law. We caution you not to place undue reliance on the forward-looking statements, which speak only as of the date of this filing.

Margin Deposits, Clearing Funds, and Interoperability Funds

Due to an update in its rules, effective August 14, 2023, Cboe Clear Europe may invest interoperability fund deposits provided by clearing participants subsequent to the effective date of the rules change. In accordance with the updated policy, Cboe Clear Europe has the option to maintain cash deposits provided by clearing participants at Clearstream Banking S.A., in the same manner done previously, or invest the cash in certain investments within the parameters of its investment policy. As such, the interoperability fund deposits are reflected in the condensed consolidated balance sheet as of the effective date of the rules change. Changes in margin deposits, clearing funds, and interoperability funds, are presented net in the “restricted cash and cash equivalents and customer bank deposits (included in margin deposits, clearing funds, and interoperability funds)” line in the operating section of the condensed consolidated statement of cash flows. Similarly, cash flows associated with related investment agreements as well as interest income earned on such investments will be classified as cash flows from operating activities in the condensed consolidated statement of cash flows. Both activities are part of Cboe Clear Europe’s principal operating activities and are presented within the operating section of the condensed consolidated statement of cash flows.

When investments are made in accordance with the Regulation Investment Policy, Cboe Clear Europe receives the amount of investment earnings and pays clearing participants those earnings minus a set basis point cost of collateral.

2.   REVENUE RECOGNITION

The Company presents three financial statement revenue captions within its condensed consolidated statements of income that reflect the Company’s diversified products, expansive geographical reach, and overall business strategy. Below is a summary of the Company’s financial statement revenue captions:

Revenues

● Cash and spot markets – includes associated transaction and clearing fees, the portion of market data fees relating to associated U.S. tape plan market data fees, associated regulatory fees, and associated other revenue from Cboe’s North American Equities, Europe and Asia Pacific, Global FX, and Digital segments.

● Data and access solutions – includes access and capacity fees, proprietary market data fees, and associated other revenue across Cboe’s six segments.

● Derivatives markets – includes associated transaction and clearing fees, the portion of market data fees relating to associated U.S. tape plan market data fees, associated regulatory fees, and associated other revenue from Cboe’s Options, Futures, Europe and Asia Pacific, and Digital segments.

The Company’s main types of revenue contracts consist of the following, which are disaggregated from the condensed consolidated statements of income.

● Transaction and clearing fees – Transaction fees represent fees charged by the Company for meeting the point-in-time performance obligation of executing a trade on its markets. These fees can be variable based on trade volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Transaction fees are recognized across all segments. Clearing fees, which include settlement fees, represent fees charged by the Company for meeting the point-in-time performance obligation for transactions cleared and settled by Cboe Clear Europe and Cboe Clear Digital, the derivatives clearing organization for Cboe Digital. Clearing fees can be variable based on trade volume tiered discounts; however, as

15

all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Clearing fees are recognized in the Europe and Asia Pacific and Digital segments. Transaction and clearing fees, as well as any tiered volume discounts, are calculated and billed monthly in accordance with the Company’s published fee schedules.

● Access and capacity fees – Access and capacity fees represent fees assessed for the opportunity to trade, including fees for trading-related functionality across all segments, terminal and other equipment rights, maintenance services, trading floor space and telecommunications services. Facilities, systems services and other fees are generally monthly fee-based. These fees are billed monthly in accordance with the Company’s published fee schedules and recognized on a monthly basis when the performance obligations are met. All access and capacity fees associated with the trading floor are recognized over time in the Options segment, as the performance obligations are met.

● Market data fees – Market data fees represent the fees received by the Company from the U.S. tape plans and fees charged to customers for proprietary market data. Fees from the U.S. tape plans are collected monthly based on published fee schedules and distributed quarterly to the Exchanges based on a known formula. A contract for proprietary market data is entered into and charged on a monthly basis in accordance with the Company’s published fee schedules as the service is provided. Proprietary market data also includes revenue from various licensing agreements. Both types of market data are satisfied over time, and revenue is recognized on a monthly basis as the customer receives and consumes the benefit as the Company provides the data to meet its performance obligation. U.S. tape plan market data is recognized in the North American Equities and Options segments. Proprietary market data fees are recognized across all segments.

● Regulatory fees – There are two types of regulatory fees that the Company recognizes. The first type represents fees collected by the Company to cover the Section 31 fees charged to the Exchanges by the SEC for meeting the point-in-time performance obligation of executing a trade on its markets. The fees charged to customers are based on the fee set by the SEC per notional value of U.S. Equities exchange transactions and per round turn of Options transactions executed on the Company’s U.S. securities markets. These fees are calculated and billed monthly and are recognized in the North American Equities and Options segments. As the Exchanges are responsible for the ultimate payment to the SEC, the Exchanges are considered the principal in these transactions. Regulatory fees also include the options regulatory fee (“ORF”) which supports the Company’s regulatory oversight function in the Options segment, along with other miscellaneous regulatory fees, and neither can be used for non-regulatory purposes. The ORF and miscellaneous fees are recognized when the performance obligation is fulfilled.

● Other revenue – Other revenue primarily includes interest income on investments (including from investments of interoperability fund deposits) from clearing operations, all fees related to the trade reporting facility operated in the Europe and Asia Pacific segment, listing fees, and revenue associated with advertisements through the Company’s websites.

All revenue recognized in the condensed consolidated statements of income is considered to be revenue from contracts with customers, with the exception of interest income from clearing operations.

These transaction fees are amortized and recorded ratably as the transactions occur over the period.

3.   ACQUISITIONS

On May 2, 2022, the Company purchased ErisX, which was subsequently rebranded to Cboe Digital. Cboe Digital operates a U.S. based digital asset spot market, a regulated futures exchange and a regulated clearinghouse. Ownership of Cboe Digital allows the Company to enter the digital asset spot and derivatives marketplaces through a digital-first platform developed with industry partners to focus on robust regulatory compliance, data and transparency. Eris Innovations Holdings, LLC (formerly Eris Exchange Holdings, LLC) was not a part of this transaction and the Company retains its minority equity ownership interest in Eris Innovations Holdings, LLC. Of the acquisition’s purchase price, $460.9 million was allocated to goodwill, $95.0 million was allocated to intangible assets, and $8.4 million was allocated to working capital. Prior to signing the acquisition agreement, the Company held a minority investment in ErisX. As a result of the acquisition of the remaining portion of ErisX, the Company recognized a $7.5 million gain, reflecting the change in fair value of the minority investment in ErisX as a result of the acquisition, which is included in other income (expense), net in the condensed consolidated statement of income for the year ended December 31, 2022. See below for further discussion of intangible assets acquired. Additionally, the Company performed impairment testing during the year ended December 31, 2022, as there were market events that indicated it was more likely than not that these assets were impaired, resulting in the recognition of impairment charges to goodwill. See Note 8 (“Goodwill, Intangible Assets, Net, and Digital Assets Held”) for more information on the impairments.

On June 1, 2022, the Company purchased NEO, which was subsequently rebranded to Cboe Canada. Cboe Canada is a fintech organization that is comprised of a fully registered Canadian securities exchange with a diverse product and services set ranging from corporate listings to cash equities trading and a non-listed securities distribution platform. With ownership of Cboe Canada, the Company expects to further grow Canada as a hub for global equities trading, in addition to MATCHNow, the ATS acquired by the Company in 2020. As of December 31, 2022, the allocation of purchase price includes adjustments within the measurement period resulting in a decrease to intangible assets, an increase in net working capital and a reduction in contingent consideration. See the table below for more information about the adjustments made to the Cboe Canada (formerly NEO) purchase price allocation. See below for further discussion of intangible assets acquired and Note 13 (“Fair Value Measurement”) for the impact of the allocation adjustments on the Company’s financial liabilities.

The following table presents the details of the adjustments made to the initial purchase price allocation for the Cboe Canada (formerly NEO) acquisition during the year ended December 31, 2022 (in millions):

	Initial purchase		Total		Adjusted purchase

Equity Method Investments

The Company’s investment in the 7Ridge Investments 3 LP (“7Ridge Fund”), represents a nonconsolidated variable interest entity (“VIE”). The Company has determined that consolidation of the VIE is not required as the Company is not the primary beneficiary of the 7Ridge Fund, as it does not have controlling financial interest and lacks the ability to unilaterally remove the general partner, 7Ridge Investments 3 GP Limited, direct material strategic decisions, or dissolve the entity (i.e., the Company does not have unilateral substantive “kick-out” or “liquidation” rights).

The Company’s interest in the 7Ridge Fund is equal to the carrying value of the investment as of September 30, 2023, or $288.8 million, which includes periodic capital contributions to the 7Ridge Fund, as well as the Company’s share of 7Ridge Fund’s profit or loss, including gains or losses arising from the fair value measurement of the investment held by the 7Ridge Fund, booked against the investment account. The carrying value of the investment is included in

20

investments within the condensed consolidated balance sheets. The Company’s maximum loss exposure, in the unlikely event that all of the VIE’s assets become worthless, is limited to the carrying value of the Company’s investment.

Other Equity Investments

The carrying value of other equity investments is included in investments in the condensed consolidated balance sheets. The Company accounts for these investments using the measurement alternative given the absence of readily determinable fair values for the respective investments and due to the Company’s inability to exercise significant influence over the investments based upon the respective ownership interests held. As of September 30, 2023, other equity investments primarily consist of minority investments in Eris Innovations Holdings, LLC, Globacap Technology Limited, CSD Br, Coin Metrics Inc., Cboe Vest Financial Group, Inc., Effective Investing Limited, and a 20% investment in OCC.

5.   PROPERTY AND EQUIPMENT, NET

Property and equipment, net consisted of the following as of September 30, 2023 and December 31, 2022 (in millions):

	September 30,		December 31,
	2023		2022
Construction in progress	$	2.7	$	7.7
Building		—		68.8
Furniture and equipment		309.7		291.3
Total property and equipment		312.4		367.8
Less accumulated depreciation		(206.8)		(259.6)
Property and equipment, net	$	105.6	$	108.2

Depreciation expense using the straight-line method was $8.5 million and $8.6 million for the three months ended September 30, 2023 and 2022, respectively, and $25.4 million and $25.8 million for the nine months ended September 30, 2023 and 2022, respectively.

Effective July 27, 2023, the Company entered into an agreement to sell its former headquarters building with a tentative close date in the fourth quarter of 2023, subject to customary closing conditions. The Company classified the associated land, building, and certain furniture and equipment of the former headquarters location as held for sale, performed an impairment assessment, and ceased depreciation effective August 1, 2023, as the Company anticipates selling the property held for sale in less than twelve months. In connection with the sale, the Company anticipates providing seller financing to the purchaser in the form of a promissory note for a portion of the purchase price of the former headquarters. As of September 30, 2023, the total value of the property held for sale on the condensed consolidated balance sheet was $8.7 million. The impact of ceasing depreciation of the property held for sale did not result in a material impact to the condensed consolidated financial statements.

6. CREDIT LOSSES

Current expected credit losses are estimated for accounts receivable and certain notes receivable.

Accounts receivable represent amounts due from the Company’s member firms. The allowance for accounts receivable credit losses is calculated using an aging schedule.

The allowance for notes receivable credit losses is associated with notes receivable included within other assets, net on the condensed consolidated balance sheets and relates to promissory notes to fund the implementation and operation of the consolidated audit trail (“CAT”), which notes are to be repaid by Consolidated Audit Trail, LLC (“CATLLC”). CAT involves the creation of an audit trail that is required by SEA Rule 613, and it strives to enhance regulators’ ability to monitor trading activity in the U.S. markets through a phased implementation. CATLLC is a national market system plan that was created by self-regulatory organizations that include the Company’s six Exchanges, the other U.S. national securities exchanges and FINRA (who collectively are referred to as the “Plan Participants”) to implement and operate the CAT. The funding of the CAT’s implementation and operations is ultimately expected to be provided by Plan Participants and by broker-dealers (who are referred to as “Industry Members”). However, the funding to date has solely been provided to CATLLC by the Plan Participants in exchange for promissory notes.

21

On September 6, 2023, the SEC issued an order approving an amendment to the CAT national market system plan to implement a revised funding model (“CAT Funding Model”) for CATLLC to fund the CAT. The approved CAT Funding Model contemplates two categories of CAT fees calculated based on the “executed equivalent shares” of transactions in eligible securities: (i) CAT fees assessed by CATLLC to Industry Members who are CAT Executing Brokers (as that term is defined in the CAT national market system plan) to recover a portion of historical CAT costs previously paid to CATLLC by the Plan Participants; and (ii) CAT fees assessed by CATLLC to CAT Executing Brokers and Plan Participants to fund prospective CAT costs. The Plan Participants will file fee filings with the SEC to implement the applicable transaction-based fee rates that are to be assessed by CATLLC to CAT Executing Brokers for each CAT fee. Initially, CATLLC plans to implement a CAT fee related to a portion of historical CAT costs incurred prior to 2022. The funds generated from the assessment of that CAT fee will be used by CATLLC to repay a portion of the promissory notes to the Plan Participants. Additional CAT fees related to other historical CAT costs and to prospective CAT costs are planned to be introduced at a later time. Once the CAT fee related to ongoing prospective CAT costs becomes effective through fee filings submitted by the Plan Participants, it is anticipated there will no longer be any need for promissory notes to be provided by the Plan Participants to CATLLC.

A challenge to the SEC’s September 6, 2023 order was filed by the American Securities Association and Citadel Securities, LLC against SEC before the U.S. Court of Appeals for the 11th Circuit on October 17, 2023. This challenge or any other challenge to the SEC order approving the CAT Funding Model and/or Plan Participant(s) fee filings may significantly delay implementation efforts. As a result, the Plan Participants may continue to incur additional significant costs, and/or it may result in them not being able to collect on the promissory notes related to the funding of the implementation and operation of the CAT.

Until the fees for historical CAT costs that are associated with the promissory notes are collected from CAT Executing Brokers and remitted by CATLLC to the Plan Participants, the Plan Participants may continue to incur additional significant costs, including additional promissory notes to fund CAT. The allowance for notes receivable credit losses associated with the CAT is calculated using a methodology that is primarily based on the structure of the notes and various potential outcomes under the CAT Funding Model.

The following represents the changes in allowance for credit losses during the nine months ended September 30, 2023 (in millions):

	Balance at December 31, 2022		Current period provision for expected credit losses		Write-offs charged against the allowance		Recoveries collected		Balance at September 30, 2023
Allowance for notes receivable credit losses	$	30.1	$	—	$	—	$	—	$	30.1
Allowance for accounts receivable credit losses		2.2		2.8		(0.3)		(0.1)		4.6

The following table presents the details of goodwill by segment (in millions):

			North American		Europe and
	Options		Equities		Asia Pacific		Global FX		Digital		Total

Balance as of September 30, 2023	$	305.8	$	2,000.4	$	551.5	$	267.2	$	—	$	3,124.9

Goodwill has been allocated to specific reporting units for purposes of impairment testing - Options, North American Equities, Europe and Asia Pacific, and Global FX. No goodwill has been allocated to Futures. See below for further details on Cboe Digital’s goodwill. Goodwill impairment testing is performed annually in the fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired.

Following the acquisition of Cboe Digital, which closed on May 2, 2022, in the quarter ended June 30, 2022, negative events and trends in the broader digital asset environment emerged, such as deleveraging and bankruptcies, and certain negative trends in the broader digital asset environment that started in late 2021 intensified, such as the decline in digital asset prices, overall market activity, and market capitalization. Additionally, following the acquisition of Cboe Digital, the efforts to syndicate minority ownership interests in Cboe Digital to potential investors during the quarter ended June 30, 2022 became more challenging, and the outlook for the Digital segment’s future market growth was negatively impacted. The Company considered these developments, in particular the syndication efforts during the quarter ended June 30, 2022, to be potential indications of impairment and performed an interim impairment test for the goodwill recognized in the Digital reporting unit during the quarter ended June 30, 2022. The Company concluded that the carrying value of the reporting unit exceeded its estimated fair value, which considered both market and income approaches, and recorded a goodwill impairment charge of $460.1 million in the condensed consolidated statements of income during the quarter ended June 30, 2022, and also recognized a deferred tax asset of $116.2 million. This deferred tax asset, resulting from the excess of tax-deductible goodwill over book goodwill, relates to future tax deductions the Company expects to realize to reduce potential tax payments on future income. As a result, the carrying value of Cboe Digital decreased by $343.9 million, to $220.0 million as of June 30, 2022. The Company also performed an impairment assessment over the intangible assets recognized as a result of the Cboe Digital acquisition during the quarter ended June 30, 2022, and based on the results of the assessments, determined there was no impairment required as the fair value approximated the carrying value. No other long lived assets were recognized as a result of the acquisition.

As a result of the finalization of the net working capital calculation associated with the acquisition of Cboe Digital during the quarter ended September 30, 2022, the Company recorded additional goodwill of $0.8 million. Subsequently, the Company concluded that the indicators of impairment outlined in the previous paragraph continued to be relevant and recorded an additional goodwill impairment charge of $0.8 million in the condensed consolidated statements of income for the three months ended September 30, 2022. The Company determined there were no further impairment indicators for the nine months ended September 30, 2023.

Term Loan Agreement

On March 22, 2018, the Company entered into a Term Loan Credit Agreement (the “Term Loan Agreement”). The Term Loan Agreement matures on December 15, 2023 and initially provided for a senior unsecured term loan facility in an aggregate principal amount of $300 million, which amount was later increased to allow for an additional draw of $110 million on June 25, 2021 in order to fund a portion of the acquisition of Cboe Asia Pacific (formerly Chi-X Asia Pacific Holdings Limited) and was increased on March 29, 2022 to allow for additional delayed draws of $190 million on April 29, 2022 to fund a portion of the Cboe Digital (formerly ErisX) acquisition, and $175 million on May 31, 2022 to fund a portion of the Cboe Canada (formerly NEO) acquisition. On each of August 25, 2022 and September 22, 2022, the Company repaid $50 million, respectively, of outstanding indebtedness under the Term Loan Agreement, and on each of November 1, 2022, December 1, 2022, and December 27, 2022, the Company repaid $40 million, $50 million, and $30 million, respectively, of outstanding indebtedness under the Term Loan Agreement totaling $220 million repaid during the year ended December 31, 2022. On May 12, 2023, June 21, 2023 and September 28, 2023, the Company repaid $65 million, $75 million, and $90 million respectively, of outstanding indebtedness under the Term Loan Agreement totaling $230 million repaid during the nine months ended September 30, 2023.

Loans under the Term Loan Agreement bear interest, at the Company’s option, at either (i) the Secured Overnight Financing Rate (“SOFR”) as administered by the Federal Reserve Bank of New York (or a successor administrator) plus a margin of 0.65 percent per annum or (ii) a daily floating rate based on the agent’s prime rate (subject to certain minimums based upon the federal funds effective rate or SOFR) plus a margin of 0.50 percent per annum.

25

The Term Loan Agreement contains customary representations, warranties, and affirmative and negative covenants for facilities of its type, including financial covenants, events of default, including cross-defaults from the Company’s other indebtedness, and indemnification provisions in favor of the lenders thereunder. The negative covenants include restrictions regarding the incurrence of liens, the incurrence of indebtedness by the Company’s subsidiaries and fundamental changes, subject to certain exceptions in each case. The financial covenants require the Company to meet a quarterly financial test with respect to a minimum consolidated interest coverage ratio of not less than 4.00 to 1.00 and a maximum consolidated leverage ratio of not greater than 3.50 to 1.00; provided that the consolidated leverage ratio may, subject to certain triggering events set forth in the Term Loan Agreement, be increased to 4.25 to 1.00 or 4.00 to 1.00 (from 3.50 to 1.00) for four consecutive fiscal quarters following certain acquisitions, provided this increase may be made only once and at the time it exercises such financial covenant step-up, the Company shall be exercising a like step-up under its revolving credit facility. At September 30, 2023, the Company was in compliance with these covenants and did not exercise financial covenant step-up.

Senior Notes

On January 12, 2017, the Company entered into an indenture (the “Indenture”), by and between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as trustee, in connection with the issuance of $650 million aggregate principal amount of the Company’s 3.650% Senior Notes due 2027 (“3.650% Senior Notes”). The form and terms of the 3.650% Senior Notes were established pursuant to an Officer’s Certificate, dated as of January 12, 2017, supplementing the Indenture. The Company used a portion of the net proceeds from the 3.650% Senior Notes to fund, in part, the Merger, including the payment of related fees and expenses and the repayment of Bats’ existing indebtedness, and the remainder for general corporate purposes. The 3.650% Senior Notes mature on January 12, 2027 and bear interest at the rate of 3.650% per annum, payable semi-annually in arrears on January 12 and July 12 of each year, commencing July 12, 2017.

On December 15, 2020, the Company issued $500 million aggregate principal amount of 1.625% Senior Notes due 2030 ("1.625% Senior Notes"). The form and terms of the 1.625% Senior Notes were established pursuant to an Officer’s Certificate, dated as of December 15, 2020, supplementing the Indenture. The Company used the net proceeds from the 1.625% Senior Notes to finance the acquisition of BIDS Trading, repay a portion of amounts outstanding under the term loan facility and all outstanding indebtedness under the revolving credit facility and the remainder for general corporate purposes, which may include the financing of future acquisitions or the repayment of other outstanding indebtedness. The 1.625% Senior Notes mature on December 15, 2030 and bear interest at the rate of 1.625% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, commencing June 15, 2021.

On March 16, 2022, the Company issued $300 million aggregate principal amount of 3.000% Senior Notes due 2032 (“3.000% Senior Notes” and, together with the 1.625% Senior Notes and the 3.650% Senior Notes, the “Senior Notes”). The form and terms of the 3.000% Senior Notes were established pursuant to an Officer’s Certificate, dated as of March 16, 2022, supplementing the Indenture. The Company used the net proceeds from the 3.000% Senior Notes, together with cash on hand, and the proceeds of additional borrowings, to partially fund its acquisition of Cboe Digital. The 3.000% Senior Notes mature on March 16, 2032 and bear interest at the rate of 3.000% per annum, payable semi-annually in arrears on March 16 and September 16 of each year, commencing September 16, 2022.

The Senior Notes are unsecured obligations of the Company and rank equally with all of the Company’s other existing and future unsecured, senior indebtedness, but are effectively junior to the Company’s secured indebtedness, to the extent of the value of the assets securing such indebtedness, and will be structurally subordinated to the secured and unsecured indebtedness of the Company’s subsidiaries.

The Company has the option to redeem some or all of the Senior Notes, at any time in whole or from time to time in part, at the redemption prices set forth in the applicable Officer’s Certificate. The Company may also be required to offer to repurchase the Senior Notes upon the occurrence of a Change of Control Triggering Event (as such term is defined in the applicable Officer’s Certificate) at a repurchase price equal to 101 percent of the aggregate principal amount of Senior Notes to be repurchased.

Indenture

Under the Indenture, the Company may issue debt securities, which includes the Senior Notes, at any time and from time to time, in one or more series without limitation on the aggregate principal amount. The Indenture governing the Senior Notes contains customary restrictions, including a limitation that restricts the Company’s ability and the ability of certain of the Company’s subsidiaries to create or incur secured debt. Such Indenture also limits certain sale and

26

leaseback transactions and contains customary events of default. At September 30, 2023, the Company was in compliance with these covenants.

Revolving Credit Agreement

On February 25, 2022, the Company entered into a Second Amended and Restated Credit Agreement (the “Revolving Credit Agreement”), which amended and restated the prior revolving credit agreement.

The Revolving Credit Agreement provides for a senior unsecured $400 million three-year revolving credit facility (the “Revolving Credit Facility”) that includes a $25 million swing line sub-facility. The Company may also, subject to the agreement of the applicable lenders, increase the commitments under the Revolving Credit Facility by up to $200 million, for a total of $600 million. Subject to specified conditions, the Company may designate one or more of its subsidiaries as additional borrowers under the Revolving Credit Agreement provided that the Company guarantees all borrowings and other obligations of any such subsidiaries under the Revolving Credit Agreement. As of September 30, 2023, no subsidiaries were designated as additional borrowers.

Funds borrowed under the Revolving Credit Agreement may be used to fund working capital and for other general corporate purposes, including the making of any acquisitions the Company may pursue in the ordinary course of its business. As of September 30, 2023, no borrowings were outstanding under the Revolving Credit Agreement. Accordingly, at September 30, 2023, $400 million of borrowing capacity was available for the purposes permitted by the Revolving Credit Agreement.

Loans under the Revolving Credit Agreement will bear interest, at the Company’s option, at either (i) the Relevant Rate (defined herein) plus a margin (based on the Company’s public debt ratings) ranging from 0.75 percent per annum to 1.25 percent per annum or (ii) a daily fluctuating rate based on the administrative agent’s prime rate (subject to certain minimums based upon the federal funds effective rate or Term SOFR), which is subject to a 1 percent floor, plus a margin (based on the Company’s public debt ratings) ranging from zero percent per annum to 0.25 percent per annum. “Relevant Rate” means with respect to any committed borrowing or swingline borrowing denominated in (a) Dollars, Term SOFR plus a spread adjustment of 0.10 percent per annum, (b) Sterling, SONIA plus a spread adjustment of 0.0326 percent per annum and (c) Euros, EURIBOR, as applicable, provided that each Relevant Rate is subject to a 0 percent floor.

Subject to certain conditions stated in the Revolving Credit Agreement, the Company and any subsidiaries designated as additional borrowers may borrow, prepay and reborrow amounts under the Revolving Credit Facility at any time during the term of the Revolving Credit Agreement. The Revolving Credit Agreement will terminate and all amounts owing thereunder will be due and payable on February 25, 2027, unless the commitments are terminated earlier, either at the request of the Company or, if an event of default occurs, by the lenders (or automatically in the case of certain bankruptcy-related events). The Revolving Credit Agreement contains customary representations, warranties, and affirmative and negative covenants for facilities of its type, including financial covenants, events of default and indemnification provisions in favor of the lenders. The negative covenants include restrictions regarding the incurrence of liens, the incurrence of indebtedness by the Company’s subsidiaries and fundamental changes, subject to certain exceptions in each case. The financial covenants require the Company to meet a quarterly financial test with respect to a minimum consolidated interest coverage ratio of not less than 4.00 to 1.00 and a maximum consolidated leverage ratio of not greater than 3.50 to 1.00; provided that the consolidated leverage ratio may, subject to certain triggering events set forth in the Revolving Credit Agreement, be increased to 4.25 to 1.00 on one occasion and 4.00 to 1.00 on another occasion, in each case, for four consecutive fiscal quarters; provided that, prior to the exercise of the second such financial covenant step-up, the maximum consolidated leverage ratio shall have returned to a level of 3.50 to 1.00 for at least two consecutive fiscal quarters. At September 30, 2023, the Company was in compliance with these covenants and did not exercise financial covenant step-up.

Cboe Clear Europe Credit Facility

On July 1, 2020, EuroCCP (subsequently rebranded to Cboe Clear Europe), as borrower, the Company, as guarantor, entered into a Facility Agreement (as subsequently amended and restated, the “Facility” or “Cboe Clear Europe Credit Facility”) with Bank of America Merrill Lynch International Designated Activity Company, as co-ordinator, facility agent, lender, sole lead arranger and sole bookrunner, Citibank N.A., as security agent, and certain other lenders named therein. The Facility was amended and restated, on July 1, 2021, June 30, 2022, and June 29, 2023, as described below.

27

The Facility provides for a €1.25 billion committed syndicated multicurrency revolving and swingline credit facility (i) that is available to be drawn by Cboe Clear Europe towards (a) financing unsettled amounts in connection with the settlement of transactions in securities and other items processed through Cboe Clear Europe’s clearing system and (b) financing any other liability or liquidity requirement that Cboe Clear Europe incurred in the operation of its clearing system and (ii) under which the scheduled interest and fees on borrowings (but not the principal amount of any borrowings) are guaranteed by the Company. Subject to certain conditions, Cboe Clear Europe is able to increase the commitments under the Facility by up to €500 million, to a total of €1.75 billion.

Borrowings under the Facility are secured by cash, eligible government bonds and eligible equity assets deposited by Cboe Clear Europe into secured accounts. In addition, Cboe Clear Europe must ensure that at all times the aggregate of (a) each clearing participant’s contribution to the relevant clearing fund, (b) each clearing participant’s margin amount and (c) any cash equities purchased using the proceeds of the assets described in (a) and (b), less the amount of any such clearing participant contribution, margin amount or cash equities which have been transferred to (or secured in favor of) any provider of settlement or custody services to Cboe Clear Europe, is not less than €500 million.

Borrowings under the Facility’s revolving loans and non-U.S. dollar swingline loans bear interest at the relevant floating base rate plus a margin of 1.60 percent per annum and (subject to certain conditions) borrowings under the Facility’s U.S. dollar swingline loans bear interest as the higher of the relevant agent’s prime commercial lending rate for U.S. dollars and 0.5 percent per annum over the federal funds effective rate. A commitment fee of 0.275 percent per annum is payable on the unused and uncalled amount of the Facility during the availability period.

Subject to certain conditions stated in the Facility, Cboe Clear Europe may borrow, prepay and reborrow amounts under the Facility at any time during the term of the Facility. The Facility will terminate and all amounts owing thereunder will be due and payable on June 28, 2024, unless the commitments are terminated earlier, either at the request of Cboe Clear Europe or, if an event of default occurs, by the Lenders (or automatically in the case of certain bankruptcy-related events).

The Facility contains customary representations, warranties and covenants for facilities of its type, including events of default of the Company and Cboe Clear Europe and indemnification provisions in favor of the Lenders. In particular, the covenants include restrictions regarding the incurrence of liens by Cboe Clear Europe and its subsidiaries, and an event of default will be triggered if Cboe Clear Europe ceases its business, subject to certain exceptions in each case. There is also a requirement for the net worth of (a) the Company to be no less than $1.75 billion on the date of each drawdown and delivery of compliance certificates and (b) Cboe Clear Europe to be the higher of €30 million and any such amount required for Cboe Clear Europe to meet minimum liquidity regulations under applicable regulation at all times.

As of September 30, 2023, no borrowings were outstanding under the Facility. Accordingly, at September 30, 2023, €1.25 billion of borrowing capacity was available for the purposes permitted by the Facility. At September 30, 2023, the Company and Cboe Clear Europe were in compliance with applicable covenants.

Small Business Administration’s Paycheck Protection Program

On May 1, 2020, prior to Cboe’s acquisition of Cboe Digital, Cboe Digital (formerly ErisX) received $1.3 million of proceeds from a loan issued under either the Small Business Administration ("SBA") Paycheck Protection Program ("PPP") under section 7(a)(36) of the Small Business Act or the SBA's Paycheck Protection Program Second Draw Loans under Section 7(a)(37) of the SBA. On May 26, 2022, the PPP loan was forgiven and no further balance is due.

12. CLEARING OPERATIONS

Cboe Clear Europe

Cboe Clear Europe is a European equities central counterparty that provides post-trade services to stock exchanges, MTFs, over-the-counter (“OTC”) equities trades and an equity index derivatives exchange. Cboe Clear Europe clears equities from eighteen European markets and the United States, as well as Depositary Receipts, ETFs, and exchange traded currencies (“ETCs”). In September 2021 Cboe Clear Europe began clearing equity index derivatives for ten European markets. Through a novation process, Cboe Clear Europe becomes the buyer for every seller and the seller for every buyer, thereby protecting clearing participants from counterparty risk and allowing the settlement of trades in the event of a clearing participant default.

29

Cboe Clear Europe only assumes the guarantor role if it has an equal and offsetting claim against a clearing participant. For the period ended September 30, 2023, there have been no events of default for which a liability is required to be recognized in accordance with GAAP.

Clearing Participant Deposits

Cboe Clear Europe generally requires all clearing participants to deposit collateral to help mitigate Cboe Clear Europe’s exposure to credit risk in the event that a clearing participant fails to meet a financial or contractual obligation.

Margin Deposits

Margin deposits, which are predominately in the form of cash and cash equivalents, are deposits made by each clearing participant to Cboe Clear Europe to cover some or all of the credit risk of its failure to fulfill its obligations in the trade. Cboe Clear Europe maintains and manages all cash deposits related to margin deposits. Substantially all risks and rewards of margin deposit ownership, including net interest income, belong to Cboe Clear Europe and are recorded in cash and spot markets on the condensed consolidated statements of income. In the event of a default, Cboe Clear Europe can access the defaulting participant’s margin deposits to cover the defaulting participant’s losses. For more information, see “Default and Liquidity Waterfalls” below.

Clearing Funds

The clearing fund mutualizes the risk of default among all clearing participants. Depending on their membership, clearing participants contribute to the cash-equity and/or derivatives segment of the clearing fund. Although the entire clearing fund is available to cover potential losses in the event that the margin deposits and the clearing fund deposits of a defaulting clearing participant are inadequate to fulfill that clearing participant’s outstanding financial obligations, the clearing fund first uses the product class segment of the Clearing Fund in which the defaulting participants was active (see “Default and Liquidity Waterfalls” below). In the event of a default, Cboe Clear Europe is generally required to liquidate the defaulting clearing participant’s open positions. To the extent that the positions remain open, Cboe Clear Europe is required to assume the defaulting clearing participant’s obligations related to the open positions. Clearing participants are required to make contributions to the clearing fund that are proportional to their risk exposure in the form of cash or non-cash contributions, which generally consist of highly liquid securities.

Interoperability Fund

For the cash equity business line, Cboe Clear Europe has entered into interoperable arrangements with two other central counterparties (“CCPs”). Under these arrangements, margin is pledged to and from interoperable CCPs. The interoperability fund consists of collateral provided by clearing participants that is pledged by Cboe Clear Europe to the other interoperable CCPs, to cover margin calls Cboe Clear Europe receives from such interoperable CCPs.

As described in Note 1 (“Organization and Basis of Presentation”), effective August 14, 2023, Cboe Clear Europe enacted changes to its rules, and is able to invest the cash collateral received in the form of interoperability fund deposits from clearing participants in certain investments, typically securities issued by pre-approved sovereign issuers and reverse repurchase agreements with overnight maturities. When investments are made in accordance with the Regulation Investment Policy, Cboe Clear Europe receives the amount of investment earnings and pays clearing participants those earnings minus a set basis point cost of collateral. As Cboe Clear Europe is able to direct the investment of the cash interoperability fund deposits received from the clearing participants within the program parameters and receives an economic benefit from those investments, these amounts are included in the Margin Deposits, Clearing Funds, and Interoperability fund captions in the condensed consolidated balance sheets and the related interest income and expense is recorded in other revenue and other costs of revenue respectively on the condensed consolidated statements of income.

30

The details of our margin deposits, clearing funds, and interoperability funds as of September 30, 2023 and December 31, 2022, are as follows (in millions):

	September 30, 2023
	Margin Deposits		Clearing Funds		Interoperability Funds
Central bank account	$	496.0	$	88.9	$	345.9
Reverse repurchase and other		71.5		4.1		302.5
Cash contributions		567.5		93.0		648.4
Non-cash contributions (1)		426.0		44.3		241.3
Total	$	993.5	$	137.3	$	889.7

	December 31, 2022
	Margin Deposits		Clearing Funds		Interoperability Funds (2)
Cash contributions	$	426.9	$	103.4	$	376.0
Non-cash contributions (1)		338.2		38.6		89.3
Total	$	765.1	$	142.0	$	465.3

(1) These amounts are not reflected in the condensed consolidated balance sheets, as Cboe Clear Europe does not have the ability to sell or repledge the amounts absent a clearing participant default.

(2) The interoperability funds were not reflected in the condensed consolidated balance sheet as of December 31, 2022, as Cboe Clear Europe did not have the ability to invest the balances at that point in time. See the updated rule change discussed in Note 1 (“Organization and Basis of Presentation”) for additional information.

Default and Liquidity Waterfalls

The default waterfall is the priority order in which the capital resources are expected to be utilized in the event of a default where the defaulting clearing participant’s collateral would not be sufficient to cover the cost to liquidate its portfolio. If a default occurs and the defaulting clearing participant’s collateral, including margin deposits and clearing fund deposits, are depleted, then additional capital is utilized in the following order:

● Cboe Clear Europe dedicated own resources: The Cboe Clear Europe default waterfall first utilizes its dedicated own resources in two forms and totaling 35% of Cboe Clear Europe capital requirements; the ‘first skin in the game’, equal to 25% of Cboe Clear Europe capital requirements before the use of clearing fund contributions described below and the ‘second skin in the game’, an amount between 10-25% of capital requirements as discussed in Note 16 (“Regulatory Capital”).

● Clearing fund: Second, the Cboe Clear Europe default waterfall utilizes traditional CCP risk mutualization, in the event that default losses fully exhaust Cboe Clear Europe’s dedicated own resources amount, whereby contributions applicable to a particular product class are applied first to any loss attributable to that product class.

● Pro rata contributions: Third, if the default losses caused cannot be covered by the first two layers, the non-defaulting clearing participants shall on demand make additional payments to Cboe Clear Europe on a pro rata basis in proportion to the amount of their clearing fund contributions to cover any such remaining losses, which is limited to an amount equal to twice their clearing fund contribution as established under Cboe Clear Europe’s rules and regulations. In this scenario, contributions applicable to a particular product class are first applied to any losses attributable to that product class.

In addition to the default waterfall, the liquidity waterfall is the priority order in which the liquidity resources are expected to be utilized for Cboe Clear Europe’s ordinary course business operations and in situations when additional liquidity resources and liquidity measures may be activated in case of a potential liquidity shortfall. Liquidity, intraday or overnight, is mainly required for securities settlement. In ordinary course business circumstances, liquidity resources include the collateral directly deposited with Cboe Clear Europe, FX swap arrangements, and reverse repurchase agreements, as well as the use of the Facility.

Cboe Clear Digital

Cboe Clear Digital is a digital asset and digital asset derivatives clearinghouse and central counterparty that provides clearing and settlement of digital asset trades. Cboe Clear Digital is registered as a Derivatives Clearing Organization (“DCO”) regulated by the U.S. Commodity Futures Trading Commission (“CFTC”) and is registered with the U.S. Treasury

31

Financial Crimes Enforcement Network (“FinCEN”) as a money services business (“MSB”). Cboe Clear Digital is authorized, by license or not subject to licensing, to conduct MSB services in 50 U.S. jurisdictions. Cboe Clear Digital performs a guarantee function whereby Cboe Clear Digital helps to ensure that the obligations of the transactions it clears are fulfilled. Cboe Clear Digital attempts to mitigate this risk by performing internal compliance and due diligence procedures as well as implementing internal risk controls. Cboe Clear Digital 's due diligence procedures include review of the personal and corporate information, financial position of the member participant, and monitoring of Cboe Clear Digital's risk exposure thresholds. As of September 30, 2023, Cboe Clear Digital does not expect a material loss concerning credit risk on any member participant. In accordance with the SEC issued Staff Accounting Bulletin 121 (“SAB 121”), the Company includes customer cash deposits on the condensed consolidated balance sheets in margin deposits and clearing funds and includes customer digital assets on the condensed consolidated balance sheets in digital assets – safeguarded assets, with a corresponding offset in digital assets – safeguarded liabilities.

The table below presents the Company’s cash deposits and safeguarded digital assets held on behalf of its customers for the purposes of supporting clearing transactions as of September 30, 2023 and December 31, 2022 (in millions):

	September 30, 2023		December 31, 2022
Customer bank deposits	$	15.8	$	12.7
Digital assets - safeguarded assets		40.2		22.9

13.  FAIR VALUE MEASUREMENT

Fair value is the price that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the Company’s own credit risk.

The Company applied FASB Accounting Standards Codification (“ASC”) 820 — Fair Value Measurement, which provides guidance for using fair value to measure assets and liabilities by defining fair value and establishing the framework for measuring fair value. ASC 820 applies to financial and nonfinancial instruments that are measured and reported on a fair value basis. The three-level hierarchy of fair value measurements is based on whether the inputs to those measurements are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The fair value hierarchy requires the use of observable market data when available and consists of the following levels:

● Level 1—Unadjusted inputs based on quoted markets for identical assets or liabilities.

● Level 2—Observable inputs, either direct or indirect, not including Level 1 measurements, corroborated by market data or based upon quoted prices in non-active markets.

● Level 3—Unobservable inputs that reflect management’s best assumptions of what market participants would use in valuing the asset or liability.

32

The Company has included a tabular disclosure for financial assets and liabilities that are measured at fair value on a recurring basis in the condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022, respectively.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

(2) These amounts are reflected within other non-current liabilities in the condensed consolidated balance sheets.

The following is a description of the Company’s valuation methodologies used for instruments measured at fair value on a recurring basis:

Financial Investments

Financial investments consist of highly liquid U.S. Treasury securities, and marketable securities held in a trust for the Company’s non-qualified retirement and benefit plans, also referred to as deferred compensation plan assets. The deferred compensation plan assets have an equal and offsetting deferred compensation plan liability based on the value of the deferred compensation plan assets. These securities are valued by obtaining feeds from a number of live data sources, including active market makers and inter dealer brokers and therefore categorized as Level 1. No material adjustments were made to the carrying value of financial investments for the period ended September 30, 2023. See Note 15 (“Employee Benefit Plans”) for more information.

33

Digital Assets – Safeguarded Assets and Liabilities

Digital assets – safeguarded assets and liabilities consist of Bitcoin, Ethereum, Litecoin, Bitcoin Cash, and USD Coin. The Company has determined the principal marketplace for digital assets to be the spot market of Cboe Digital Exchange, LLC (“Cboe Digital Exchange”). The Company valued digital assets – safeguarded assets, and digital assets – safeguarded liabilities by using the closing prices at 4:00pm Central Time on Cboe Digital Exchange’s spot market (“Cboe Digital spot market”) as of September 30, 2023. These inputs are categorized in the fair value hierarchy as Level 1 as the marketplace is considered active. See Note 12 (“Clearing Operations”) for additional details regarding digital assets held.

Contingent Consideration Liabilities

In connection with the acquisitions of Hanweck Associates, LLC (“Hanweck”), Cboe Asia Pacific, and Cboe Canada, the Company entered into contingent consideration arrangements with the sellers. The total fair value of the liabilities at September 30, 2023 was $28.2 million. That value is based on the Company’s estimate of the likelihood that certain performance targets in the respective acquisition agreements are expected to be accomplished. In connection with the contingent consideration arrangements, the Company paid a total of $10.9 million in contingent consideration to the sellers of Hanweck, Cboe Asia Pacific and Cboe Canada during the nine months ended September 30, 2023. Because the fair value measurements relating to the contingent consideration liabilities are subject to management judgment, measurement uncertainty is inherent in the valuation of the contingent consideration liabilities as of the reporting date. Based on the recorded balance of the liabilities, any measurement uncertainty related to this Level 3 measurement is immaterial as of September 30, 2023.

Cboe Digital Syndication Liabilities

On November 18, 2022, Cboe Digital Holdings Inc. (“Cboe Digital Holdings”) entered into minority interest purchase agreements with certain digital asset industry participants, pursuant to which Cboe Digital Holdings agreed to issue Restricted Common Units in Cboe Digital. Cboe Digital Holdings also entered into a Warrant Agreement to issue Common Units of Cboe Digital in the future. Certain Cboe Digital investor members paid for the Restricted Common Units through the issuance of promissory notes, which are nonrecourse in nature and are accounted for as in-substance stock options. The cost associated with the Restricted Common Units is recognized as contra-revenue ratably over a five-year period. The Company uses a Black Scholes option pricing model to estimate the fair value of the in-substance stock option created by the Restricted Common Units and promissory notes as well as the fair value of the Warrant. Contra-revenue will be recognized while the performance conditions of the Warrant remain probable in conformance with the requirements in ASC 606 – Revenue from Contracts with Customers. Further adjustments will be recognized in each reporting period until performance is complete relating to changes in the fair value of the option and Warrant liabilities in accordance with ASC 718 – Compensation – Stock Compensation. Based on the recorded balance of the liabilities, any measurement uncertainty related to this Level 3 measurement is immaterial as of September 30, 2023. See Note 17 (“Stock-Based Compensation”) for more information.

Certain Cboe Digital investor members can earn additional Restricted Common Units if they meet certain performance-based metrics outlined in an equity incentive program (“Incentive Program Units”). The Incentive Program Units are subject to the same terms and conditions as the other Restricted Common Units and are similarly liability-classified awards. Cboe Digital authorized a maximum of 20 Common Units to be distributed over the two-year life of the incentive program. The cost associated with the Incentive Program Units will be recognized as contra-revenue ratably over the remaining service period associated with the Incentive Program Units. Further adjustments will be recognized in each reporting period until performance is complete relating to changes in the fair value of the incentive program liabilities in accordance with ASC 718 – Compensation – Stock Compensation. Based on the recorded balance of the liabilities, any measurement uncertainty related to this Level 3 measurement is immaterial as of September 30, 2023. See Note 17 (“Stock-Based Compensation”) for more information.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain assets, such as goodwill and intangible assets, are measured at fair value on a non-recurring basis. For goodwill, the process involves using a market approach and income approach (using discounted estimated cash flows) to determine the fair value of each reporting unit on a stand-alone basis. That fair value is compared to the carrying value of the reporting unit, including its recorded goodwill. In connection with the annual impairment evaluation of goodwill and indefinite lived intangibles, impairment is considered to have occurred if the fair value of the reporting unit is lower than the carrying value of the reporting unit. See “Digital Assets Held” below and Note 1 (“Organization and Basis of Presentation”) for discussion of valuation considerations specific to digital assets held. For the other intangible assets, the process also involves using a discounted cash flow method to determine the fair value of each intangible asset.

34

Impairment is considered to have occurred if the fair value of the intangible asset is lower than its carrying value. These measurements are considered Level 3 and these assets are recognized at fair value if they are deemed to be impaired. In addition, property held for sale as of September 30, 2023 was also measured at fair value at September 30, 2023. See Note 5 (“Property and Equipment, Net”) for more information on property held for sale.

The Company performed impairment testing during the quarter ended June 30, 2022, as there were market events that indicated it was more likely than not that Cboe Digital’s assets were impaired, resulting in the recognition of an impairment charge to goodwill related to Cboe Digital. Subsequently, the Company concluded that the indicators of impairment observed during the quarter ended June 30, 2022, continued to be relevant and recorded additional goodwill impairment in the condensed consolidated statements of income for the three months ended September 30, 2022. The Company determined there were no further impairment indicators for the period ended September 30, 2023. See Note 8 (“Goodwill, Intangible Assets, Net, and Digital Assets Held”) for more information on the impairment.

Equity investments without readily determinable fair values that are valued using the measurement alternative are measured at fair value on a non-recurring basis. No observable transactions or impairments impacted the measurements of the investments accounted for as other equity investments. See Note 4 (“Investments”) for more information.

Fair Value of Assets and Liabilities

The following tables present the Company’s fair value hierarchy for certain assets and liabilities held by the Company as of September 30, 2023 and December 31, 2022 (in millions):

(2) These amounts are reflected within intangible assets, net in the condensed consolidated balance sheets.

(3) These amounts are reflected within other non-current liabilities in the condensed consolidated balance sheets.

35

Certain financial assets and liabilities, including cash and cash equivalents, accounts receivable, income tax receivable, accounts payable and Section 31 fees payable, and notes receivable are not measured at fair value on a recurring basis, but the carrying values approximate fair value due to their liquid or short-term nature.

Debt

The debt balance consists of fixed rate Senior Notes and a floating rate Term Loan Agreement. The fair values of the Senior Notes are classified as Level 2 under the fair value hierarchy and are estimated using prevailing market quotes. The fair value of the Term Loan Agreement was determined by utilizing a discounted cash flow analysis and is considered a Level 2 measurement.

At September 30, 2023 and December 31, 2022, the fair values of the Company’s debt obligations were as follows (in millions):

	Fair Value
	September 30, 2023		December 31, 2022
Term Loan Agreement	$	71.8	$	306.3
3.650% Senior Notes		615.3		623.6
1.625% Senior Notes		380.3		390.7
3.000% Senior Notes		244.1		253.3

Digital Assets Held

Digital assets held, which are included within intangible assets, net in the condensed consolidated balance sheets, are valued following a review of exchange prices for each specific digital asset throughout the period ended September 30, 2023. The Company will impair to the lowest observable value during the period for each digital asset type in accordance with Cboe Digital’s policy, which states that the Company values digital assets held by using the closing prices at 4:00pm Central Time on Cboe Digital Exchange’s spot market, which the Company determined is the principal marketplace for digital assets. As part of Cboe Digital’s pricing policy, the closing price on Cboe Digital’s spot market is compared to three other exchanges (Coinbase, Bitstamp, and Kraken) and the CoinDesk Price Index to assess for reasonableness. These inputs are categorized in the fair value hierarchy as Level 1 as the marketplace is considered active.

14.  SEGMENT REPORTING

The Company operates six reportable business segments: Options, North American Equities, Europe and Asia Pacific, Futures, Global FX, and Digital which is reflective of how the Company's chief operating decision-maker reviews and operates the business, as discussed in Note 1 (“Organization and Basis of Presentation”). Segment performance is primarily evaluated based on operating income (loss). The Company’s chief operating decision-maker does not use segment-level assets or income and expenses below operating income (loss) as key performance metrics; therefore, such information is not presented below. The Company has aggregated all of its corporate costs, as well as other business ventures, within the Corporate Items and Eliminations totals based on the decision that those activities should not be used to evaluate the operating performance of the segments; however, operating expenses that relate to activities of a specific segment have been allocated to that segment. 

Options. The Options segment includes options on market indices (“index options”), as well as on the stocks of individual corporations (“equity options”), and options on ETPs, such as exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”), which are “multi-listed” options and listed on a non-exclusive basis. These options are eligible to trade, as applicable, on Cboe Options, C2, BZX, EDGX, and/or other U.S. national security exchanges. Cboe Options is the Company’s primary options market and offers trading in listed options through a single system that integrates electronic trading and traditional open outcry trading on the Cboe Options trading floor in Chicago. C2 Options, BZX Options, and EDGX Options are all-electronic options exchanges, and typically operate with different market models and fee structures than Cboe Options. The Options segment also includes applicable market data fees generated from the consolidated tape plans, the licensing of proprietary options market data, index licensing, and access and capacity services.

North American Equities. The North American Equities segment includes listed U.S. equities and ETP transaction services that occur on fully electronic exchanges owned and operated by BZX, BYX, EDGX, and EDGA, equities transactions that occur on the BIDS Trading platform, and Canadian equities and other transaction services that occur on or through the MATCHNow ATS and Cboe Canada. The North American Equities segment also includes listing services on Cboe Canada Exchange, ETP listings on BZX, the Cboe Global Markets, Inc. common stock listing, applicable market

37

data fees generated from the consolidated tape plans, the licensing of proprietary equities market data, routing services, and access and capacity services.

The Europe and Asia Pacific segment includes the pan-European listed equities and derivatives transaction services, ETPs, exchange-traded commodities, and international depository receipts that are hosted on MTFs operated by Cboe Europe Equities (Cboe Europe and Cboe NL equities exchanges) and Cboe Europe Derivatives (“CEDX”). It also includes the ETP listings business on RMs and clearing activities of Cboe Clear Europe, as well as the equities transaction services of Cboe Australia and Cboe Japan, operators of trading venues in Australia and Japan, respectively. Cboe Europe operates lit and dark books, a periodic auctions book, and Cboe BIDS Europe, a Large-in-Scale (“LIS”) trading negotiation facility for UK symbols. Cboe NL, launched in October 2019 and based in Amsterdam, operates similar business functionality to that offered by Cboe Europe, and provides for trading only in European Economic Area (“EEA”) symbols. Cboe Europe Derivatives, a pan-European derivatives platform launched in September 2021, offers futures and options based on Cboe Europe equity indices. This segment also includes Cboe Europe, Cboe NL, CEDX, Cboe Australia and Cboe Japan revenue generated from the licensing of proprietary market data and from access and capacity services.

Futures. The Futures segment includes transaction services provided by CFE, a fully electronic futures exchange, which includes offerings for trading of VIX futures and other futures products, the licensing of proprietary market data, as well as access and capacity services.

The segment includes transaction services for U.S. government securities executed on the Cboe Fixed Income fully electronic trading platform.

Digital. The Digital segment includes Cboe Digital, an operator of a U.S. based digital asset spot market and a regulated futures exchange, and Cboe Clear Digital, a regulated clearinghouse, as well as revenue generated from the licensing of proprietary market data and from access and capacity services.

15.  EMPLOYEE BENEFIT PLANS

Eligible U.S. employees are eligible to participate in the Cboe Options SMART Plan (“SMART Plan”). The SMART Plan is a defined contribution plan, which is qualified under Internal Revenue Code Section 401(k). In addition, eligible employees may participate in the Supplemental Employee Retirement Plan and the Deferred Compensation Plan. Each plan is a defined contribution plan that is non-qualified under the Internal Revenue Code. The Deferred Compensation Plan assets, held in a trust, are subject to the claims of general creditors of the Company and totaled $33.5 million and $27.5 million at September 30, 2023, and December 31, 2022, respectively. Although the value of the plan is recorded in financial investments on the condensed consolidated balance sheets, there is an equal and offsetting liability in other non-current liabilities. The investment results of the Deferred Compensation Plan has no impact on net income as the investment results are recorded in equal amounts to both other income (expense), net and compensation and benefits expense in the condensed consolidated statements of income. The Company contributed $3.4 million and $4.6 million to the defined contribution plans for the three months ended September 30, 2023, and 2022, respectively, and $11.1 million and $10.7 million to the defined contribution plans for the nine months ended September 30, 2023 and 2022, respectively.

Eligible employees outside of the U.S., which includes employees of Cboe Europe, Cboe NL, Cboe Clear Europe, MATCHNow, BIDS, Cboe Asia Pacific, and Cboe Canada are eligible to participate in various employee-selected stakeholder contribution plans or plans covered by local jurisdictions or by applicable laws. The Company’s contribution amounted to $1.0 million and $0.7 million for the three months ended September 30, 2023 and 2022, respectively, and $3.2 million and $2.3 million for the nine months ended September 30, 2023 and 2022, respectively. This expense is included in compensation and benefits in the condensed consolidated statements of income.

Effective January 1, 2023, Directors may contribute a percentage of their cash and equity compensation to cash and equity deferred compensation plans that are maintained by the Company and defer income taxes thereon.

16.  REGULATORY CAPITAL

17.  STOCK-BASED COMPENSATION

Stock-based compensation is based on the fair value of the award on the date of grant, which is recognized over the related service period, net of actual forfeitures. The service period is the period over which the related service is performed, which is generally the same as the vesting period. Vesting may be accelerated for certain officers and employees as a result of attaining certain age and service based requirements in the Company’s long-term incentive plan and award agreements.

Stock-based compensation expense relating to employee awards is included in compensation and benefits and acquisition-related costs in the condensed consolidated statements of income. The Company recognized stock-based compensation expense related to employee awards of $1.5 million and $7.0 million for the three months ended September 30, 2023 and 2022, respectively and $28.4 million and $23.1 million for the nine months ended September 30, 2023 and 2022, respectively. Stock-based compensation expense relating to director awards is included in professional fees and outside services in the condensed consolidated statements of income. The Company recognized stock-based compensation expense related to director awards of $0.5 million for each of the three months ended September 30, 2023 and 2022, respectively and $1.4 million for each of the nine months ended September 30, 2023 and 2022, respectively. Stock-based compensation expense relating to awards granted to investor members of Cboe Digital are recorded as contra-revenue in the condensed consolidated statements of income and is outlined further below.

The activity in the Company’s restricted stock, consisting of restricted stock awards (“RSAs”), restricted stock units (“RSUs”), and performance-based restricted stock units (“PSUs”) for the nine months ended September 30, 2023 was as follows:

RSAs and RSUs

The following table summarizes RSA and RSU activity during the nine months ended September 30, 2023:

		Weighted
	Number of	average grant
	Shares	date fair value
Nonvested stock at December 31, 2022	556,062	$	112.07
Granted	338,794		126.50
Vested	(236,487)		108.21
Forfeited	(41,822)		120.51
Nonvested stock at September 30, 2023	616,547	$	120.91

RSUs entitle the holder to one share of common stock upon vesting with the exception of certain jurisdictions where the RSUs are settled in cash, typically vest over a three-year period, and vesting accelerates upon death, disability, or the occurrence of a qualified termination following a change in control. Vesting will also accelerate upon a qualified retirement

41

where applicable and permitted. Where applicable and permitted, qualified retirement eligibility occurs once achieving 55 years of age and 10 years of service. Unvested RSUs will be forfeited if the officer, or employee leaves the Company prior to the applicable vesting date, except in limited circumstances.

RSUs granted to non-employee members of the Board of Directors have a one-year vesting period and vesting accelerates upon the occurrence of a change in control of the Company. Unvested portions of the RSUs will be forfeited if the director leaves the Board of Directors prior to the applicable vesting date.

The RSUs have no voting rights but entitle the holder to receive dividend equivalents.

There were no remaining nonvested RSAs as of September 30, 2023.

During the nine months ended September 30, 2023, to satisfy employees’ tax obligations upon the vesting of restricted stock, the Company purchased 84,706 shares of common stock totaling $11.1 million as the result of the vesting of 218,699 shares of restricted stock.

PSUs

The following table summarizes restricted stock units contingent upon achievement of performance conditions, also known as PSUs, activity during the nine months ended September 30, 2023:

		Weighted
	Number of	average grant
	Shares	date fair value
Nonvested stock at December 31, 2022	166,702	$	125.08
Granted	86,646		143.75
Vested	(55,399)		130.05
Forfeited	(55,627)		143.52
Nonvested stock at September 30, 2023	142,322	$	127.31

PSUs include awards related to earnings per share during the performance period as well as awards related to total shareholder return during the performance period. The Company used the Monte Carlo valuation model method to estimate the fair value of the total shareholder return PSUs which incorporated the following assumptions for awards granted in February 2023: risk-free interest rate (4.10)%, three-year volatility (33.5)% and three-year correlation with S&P 500 Index (0.53). Each of these performance shares has a performance condition under which the number of units ultimately awarded will vary from 0% to 200% of the original grant, with each unit representing the contingent right to receive one share of the Company’s common stock. The vesting period for the PSUs contingent on the achievement of performance conditions is three years. For each of the performance awards, the PSUs will be settled in shares of the Company’s common stock following vesting of the PSU assuming that the participant has been continuously employed during the vesting period, subject to acceleration upon death, disability, or the occurrence of a qualified termination following a change in control. Participants have no voting rights with respect to the PSUs until the issuance of the shares of common stock. Dividends are accrued by the Company and will be paid once the PSUs, contingent on the achievement of performance conditions, vest.

In the nine months ended September 30, 2023, to satisfy employees’ tax obligations upon the vesting of performance stock, the Company purchased 21,459 shares of common stock totaling $2.7 million as the result of the vesting of 55,399 shares of performance stock.

As of September 30, 2023, there were $50.4 million in total unrecognized compensation costs related to restricted stock, restricted stock units, and performance stock units. These costs are expected to be recognized over a weighted average period of 1.9 years. Forfeited PSUs include certain awards forfeited by Edward T. Tilly, former Chief Executive Officer of the Company, who resigned and voluntarily terminated his employment with the Company on September 18, 2023.

Employee Stock Purchase Plan

In May 2018, the Company’s stockholders approved an Employee Stock Purchase Plan, (“ESPP”), under which a total of 750,000 shares of the Company’s common stock will be made available for purchase to employees. The ESPP is

42

a broad-based plan that permits employees to contribute up to 10% of wages and base salary to purchase shares of the Company’s common stock at a discount, subject to applicable annual Internal Revenue Service limitations. Under the ESPP, a participant may not purchase more than a maximum of 312 shares of the Company’s common stock during any single offering period. No participant may accrue options to purchase shares of the Company’s common stock at a rate that exceeds $25,000 in fair market value of the Company’s common stock (determined at the time such options are granted) for each calendar year in which such rights are outstanding at any time. The exercise price per share of common stock shall be 85% (for eligible U.S. and international employees) of the lesser of the fair value of the stock on the first day of the applicable offering period or the applicable exercise date.

The Company records compensation expense over the offering period related to the discount that is given to employees, which totaled $0.9 million and $0.2 million for the three months ended September 30, 2023 and 2022, respectively, and $1.8 million and $0.4 million for the nine months ended September 30, 2023 and 2022, respectively. As of September 30, 2023, 552,734 shares were reserved for future issuance under the ESPP.

Cboe Digital Restricted Common Units

On November 18, 2022, Cboe Digital Holdings entered into minority interest purchase agreements with certain digital asset industry participants, pursuant to which Cboe Digital Holdings agreed to issue 185 Restricted Common Units in Cboe Digital. In addition, certain investor members and their affiliates are our customers, including trading permit holders, trading privilege holders, participants, and members. Certain Cboe Digital investor members paid for the Restricted Common Units through the issuance of promissory notes, which are nonrecourse in nature. The issuances of Restricted Common Units for nonrecourse promissory notes are accounted for as in-substance stock options. The promissory notes generally bear interest at a rate of 5% per annum and mature upon the earlier of the sale of vested Restricted Common Units, or either November 18, 2032 or November 18, 2037. One Cboe Digital investor member paid for the Restricted Common Units in exchange for cash.

The following table summarizes the option activity during the nine months ended September 30, 2023 (in millions, except number of units and contractual term):

		Weighted				Weighted
	Number of	average exercise		Aggregate		average remaining
	Units	price		intrinsic value		contractual term
Nonvested units at December 31, 2022	185	$	0.3	$	—	6 years
Granted	—		—		—
Vested	—		—		—
Outstanding at September 30, 2023	185	$	0.3	$	—	5 years

Vesting of Restricted Common Units is based on certain conditions relating to the participation and performance of the Cboe Digital investor members on the Cboe Digital platforms, generally over a five-year period. Performance is generally measured based on participation on the Cboe Digital platforms and the investor members maintaining certain average daily volumes on the platforms. Due to the existence of an option for investor members to sell their shares immediately after vesting, the options are liability classified. The options expire upon the maturity of the promissory notes, which is either November 18, 2032 or November 18, 2037, unless the options are exercised.

The cost associated with the options will be recognized as contra-revenue, net of actual forfeitures and based on the continued probability of the satisfaction of performance conditions ratably over the vesting period. At December 31, 2022, $14.0 million of contra-revenue related to the options grants was included in other assets, net within the condensed consolidated balance sheets. At March 31, 2023 the contra-revenue balance included in other assets, net within the condensed consolidated balance sheet included a $0.1 million adjustment to the Restricted Common Units contra-revenue asset as a result of the finalization of the initial grant date fair value calculation. For the three and nine months ended September 30, 2023, $0.7 million and $2.3 million of contra-revenue related to the options grants was recognized, respectively. As of September 30, 2023, $11.8 million of contra-revenue related to the options grants was included in other assets, net on the condensed consolidated balance sheet, and is expected to be recognized as contra-revenue in the condensed consolidated statements of income over the remaining contractual term.

Changes in the fair value of the options, subsequent to the grant date, is recognized in other income (expense), net in the condensed consolidated statements of income in the period in which the fair value of the options changes. The Company uses a Black Scholes pricing model to estimate the fair value of the in-substance stock options which incorporated the following assumptions as of June 30, 2023: risk-free interest rate range (3.67 to 3.78)%, expected

43

dividend rate (0)%, expected volatility (60-65)%, and expected term of 4.5 to 6.5 years. For the nine months ended September 30, 2023, there was no change in the fair value of the options grants since the grant date.

​Certain Cboe Digital investor members can earn additional Incentive Program Units. The Incentive Program Units are subject to the same terms and conditions as the other Restricted Common Units and are similarly liability-classified awards. Cboe Digital authorized a maximum of 20 Common Units to be distributed over the two-year life of the incentive program. For the three and nine months ended September 30, 2023, $0.5 million of contra-revenue related to the Incentive Program Units was recognized. As of September 30, 2023, $2.6 million of contra-revenue related to the Incentive Program Units is included in other assets, net within the condensed consolidated balance sheet and is expected to be recognized as contra-revenue in the condensed consolidated statements of income over the remaining service period associated with the Incentive Program Units.

Cboe Digital Warrants

On November 18, 2022, Cboe Digital Holdings entered into a Warrant Agreement with an investor member to acquire up to 80 Common Units of Cboe Digital, subject to certain vesting events. The investor member is a customer of Cboe Digital. The vesting of the Warrant is based upon the achievement of certain conditions relating to the service provided by the investor member over a two-year period, of which some conditions represent conditions that are not service, performance, or market conditions and, therefore, the Warrant is liability classified. As of September 30, 2023, no portion of the Warrant has vested.

The cost associated with the Warrant will be recognized as contra-revenue ratably throughout the expected life of the Warrant before exercise. For the three and nine months ended September 30, 2023, $0.3 million and $0.9 million of contra-revenue related to the Warrant was recognized, respectively. As of September 30, 2023, $5.0 million of contra-revenue related to the Warrant is included in other assets, net within the condensed consolidated balance sheet and is expected to be recognized as contra-revenue in the condensed consolidated statements of income over the remaining life of the Warrant.

The following table summarizes the Warrant activity during the nine months ended September 30, 2023 (in millions, except number of units):

		Weighted
	Number of	average exercise
	Units	price
Nonvested units at December 31, 2022	80	$	0.2
Granted	—		—
Vested	—		—
Outstanding at September 30, 2023	80	$	0.2

Changes in the fair value of the Warrant, subsequent to the grant date, is recognized in other income (expense), net in the condensed consolidated statements of income in the period in which the fair value of the Warrant changes. The Company uses a Black Scholes pricing model to estimate the fair value of the Warrant which incorporated the following assumptions as of June 30, 2023: risk-free interest rate (3.77)%, expected dividend rate (0)%, expected volatility (65)%, and expected term of 4.6 years. For the nine months ended September 30, 2023, there was no change in the fair value of the Warrant since the grant date.

18. EQUITY

Common Stock

The Company’s common stock is listed on Cboe BZX under the trading symbol CBOE. As of September 30, 2023, 325,000,000 shares of the Company’s common stock were authorized, $0.01 par value, and 108,009,417 and 105,555,989 shares were issued and outstanding, respectively. As of December 31, 2022, 325,000,000 shares of the Company’s common stock were authorized, $0.01 par value, and 107,670,248 and 105,951,199 shares were issued and outstanding, respectively. The holders of common stock are entitled to one vote per share.

44

Common Stock in Treasury, at Cost

The Company accounts for the purchase of treasury stock under the cost method with the shares of stock repurchased reflected as a reduction to Cboe stockholders’ equity and included in common stock in treasury, at cost in the condensed consolidated balance sheets. Shares repurchased under the Company’s share repurchase program are retired or they are available to be redistributed. When treasury shares are redistributed, they are recorded at the average cost of the treasury shares acquired. When treasury shares are retired, they are removed from the common stock in treasury balance. The Company held 2,453,428 and 1,719,049 shares of common stock in treasury as of September 30, 2023 and December 31, 2022, respectively.

Share Repurchase Program

In 2011, the Board of Directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and subsequently approved additional authorizations for a total authorization of $1.6 billion. The Company expects to fund repurchases primarily through the use of existing cash balances. The program permits the Company to purchase shares, through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation.

On August 16, 2022, President Biden signed into law H.R. 5376 (commonly known as the Inflation Reduction Act of 2022 or simply the “IRA”). Tax measures contained in the IRA include, among other items, a new excise tax of 1% on repurchases of stock by domestic corporations with stock traded on established securities markets. The amount on which the tax is imposed is reduced by the value of any stock issued by such corporation during the tax year and the tax generally applies to stock buy-back transactions occurring after December 31, 2022. This new tax is not expected to result in a material impact to the Company.

The Company did not repurchase shares under the Company’s share repurchase program during the three months ended September 30, 2023 and 2022, respectively. Since inception of the program through September 30, 2023, the Company has repurchased 19,576,581 shares of common stock at an average cost per share of $72.03, totaling $1.4 billion.

As of September 30, 2023 and 2022, the Company had $139.8 million and $233.3 million of availability remaining under its existing share repurchase authorizations, respectively.

Purchase of Common Stock from Employees

The Company purchased 5,376 and 1,260 shares that were not part of the publicly announced share repurchase authorization from employees for an average price paid per share of $147.06 and $120.82 during the three months ended September 30, 2023, and 2022, respectively. These shares consisted of shares retained to cover payroll withholding taxes or option costs in connection with the vesting of restricted stock awards, restricted stock units, and performance share awards.

Preferred Stock

The Company has authorized the issuance of 20,000,000 shares of preferred stock, par value $0.01 per share, issuable from time to time in one or more series. As of September 30, 2023, and December 31, 2022, the Company had no shares of preferred stock issued or outstanding.

Dividends

During the three months ended September 30, 2023, the Company declared and paid cash dividends per share of $0.55 for an aggregate payout of $58.5 million. During the three months ended September 30, 2022, the Company declared and paid cash dividends per share of $0.50 for an aggregate payout of $53.4 million.

Each share of common stock, including RSUs and PSUs, is entitled to receive dividend and dividend equivalents, respectively, if, as and when declared by the Board of Directors of the Company. The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company’s Board of Directors and may be affected by various factors, including earnings, financial condition, capital requirements, level of

45

indebtedness and other considerations the Board of Directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, the Company’s ability to pay dividends.

As a holding company, the Company’s ability to declare and continue to pay dividends in the future with respect to its common stock will also be dependent upon the ability of its subsidiaries to pay dividends to it under applicable corporate law.

19.  INCOME TAXES

The Company records income tax expense during interim periods based on the best estimate of the full year’s tax rate as adjusted for discrete items, if any, that are taken into account in the relevant interim period. Each quarter, the Company updates its estimate of the annual effective tax rate and any change in the estimated rate is recorded on a cumulative basis. The effective tax rate from continuing operations was 22.9% and 34.4% for the three months ended September 30, 2023 and 2022, respectively, and 27.7% and 61.8% for the nine months ended September 30, 2023 and 2022, respectively.

The effective tax rate for the three months ended September 30, 2023 is lower than it was for the same period in 2022 primarily as a result of the release of income tax reserves associated with penalties and interest thereon as a result of the remeasurement of tax reserves related to Section 199 deduction claims which were in dispute with the Internal Revenue Service (“IRS”). The Company has reached a settlement with the IRS under which the Company has conceded all the claimed Section 199 deductions in exchange for the IRS’s concession of penalties asserted on the Company’s Section 199 deductions. Although the parties had not completed all legal procedures to affect the settlement at September 30, 2023, the IRS provided a written response agreeing to these terms prior to September 30, 2023. The Company accordingly remeasured its Section 199 tax reserve liabilities and released its reserves associated with penalties and interest thereon for its Section 199 claims as of September 30, 2023. Subsequent to September 30, 2023, the parties have completed all legal procedures to affect the settlement.

The lower effective tax rate for the nine months ended September 30, 2023 compared to the same period in 2022 is primarily due to the circumstances outlined above, coupled with lower income before income tax provision for the nine months ended September 30, 2022 as a result of the Cboe Digital goodwill impairment.

20.  EARNINGS PER SHARE

The computation of basic net income per common share is calculated by reducing net income for the period by dividends paid or declared and undistributed net income for the period that are allocated to participating securities to arrive at net income allocated to common stockholders. Net income allocated to common stockholders is divided by the weighted average number of common shares outstanding during the period to determine net income per share allocated to common stockholders.

The computation of diluted net income per share is calculated by dividing net income allocated to common stockholders by the sum of the weighted average number of common shares outstanding plus all additional common shares that would have been outstanding if the potentially dilutive common shares had been issued. The dilutive effect is calculated using the more dilutive of the two-class or treasury stock method.

46

The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2023 and 2022 (in millions, except per share data):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Basic earnings per share numerator:
Net income	$	208.2	$	150.2	$	549.4	$	75.3
Net income allocated to participating securities		(1.1)		(0.6)		(2.7)		(0.6)
Net income allocated to common stockholders	$	207.1	$	149.6	$	546.7	$	74.7
Basic earnings per share denominator:
Weighted average shares outstanding		105.7		106.2		105.8		106.4
Basic earnings per share	$	1.96	$	1.41	$	5.17	$	0.70
Diluted earnings per share numerator:
Net income	$	208.2	$	150.2	$	549.4	$	75.3
Net income allocated to participating securities		(1.1)		(0.6)		(2.7)		(0.6)
Net income allocated to common stockholders	$	207.1	$	149.6	$	546.7	$	74.7
Diluted earnings per share denominator:
Weighted average shares outstanding		105.7		106.2		105.8		106.4
Dilutive common shares issued under stock program		0.4		0.2		0.4		0.2
Total dilutive weighted average shares		106.1		106.4		106.2		106.6
Diluted earnings per share	$	1.95	$	1.41	$	5.15	$	0.70

For the periods presented, the Company did not have shares of stock-based compensation that would have an anti-dilutive effect on the computation of diluted earnings per share.

21.  COMMITMENTS, CONTINGENCIES, AND GUARANTEES

Legal Proceedings

As of September 30, 2023, the Company was subject to various legal proceedings and claims that have not been fully resolved and that have arisen in the ordinary course of business.

The Company reviews its legal proceedings and claims, regulatory reviews and inspections and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for those contingencies where the incurrence of a loss is probable and can be reasonably estimated, and the Company discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for the condensed consolidated financial statements to not be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company’s assessment of whether a loss is remote, reasonably possible, or probable is based on its assessment of the ultimate outcome of the matter following all appeals.

As of September 30, 2023, the Company does not believe that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these legal proceedings and claims, regulatory reviews, inspections or other legal proceedings, if any, has been incurred. While the consequences of certain unresolved proceedings are not presently determinable, the outcome of any proceeding is inherently uncertain and an adverse outcome from certain matters could have a material effect on the financial position, results of operations, or cash flows of the Company in any given reporting period.

Other

As self-regulatory organizations under the jurisdiction of the SEC, Cboe Options, C2, BZX, BYX, EDGX and EDGA are subject to routine reviews and inspections by the SEC. As a designated contract market under the jurisdiction of the CFTC, CFE, and Cboe Digital Exchange are subject to routine rule enforcement reviews and examinations by the CFTC. As a derivatives clearing organization under the jurisdiction of the CFTC, Cboe Clear Digital is also subject to routine audits and examinations by state regulators. Cboe SEF, LLC is a swap execution facility registered with the CFTC and subject to routine rule enforcement reviews and examinations by the CFTC. Cboe Trading, BIDS Trading and Cboe Fixed

47

Income are subject to reviews and inspections by FINRA. The Company has from time to time received inquiries and investigative requests from the SEC’s Division of Examinations and the CFTC’s Division of Market Oversight as well as the SEC Division of Enforcement and CFTC Division of Enforcement seeking information about the Company’s compliance with its obligations as a self-regulatory organization under the federal securities laws and Commodity Exchange Act as well as members’ compliance with the federal securities laws and Commodity Exchange Act.

In addition, while Cboe Europe, Cboe Chi-X Europe, Cboe Clear Europe, Cboe NL, Cboe Australia, Cboe Japan, MATCHNow, and Cboe Canada have not been the subject of any litigation or regulatory investigation in the past that resulted in a material impact on the Company’s financial position, results of operations, liquidity or capital resources, there is always the possibility of such action in the future. As Cboe Europe and Cboe Chi-X Europe are domiciled in the UK, it is likely that any action would be taken in the UK courts in relation to litigation or by the FCA in relation to any regulatory enforcement action. As Cboe Clear Europe is domiciled in the Netherlands, it is likely that any action would be taken in the Dutch courts in relation to litigation or by the DNB or Dutch Authority for Financial Markets in relation to any regulatory enforcement action. For Cboe NL, also domiciled in the Netherlands, it is likely that any actions would be taken in the Dutch courts in relation to litigation or Dutch Authority for Financial Markets in relation to any regulatory enforcement action. As Cboe Australia is domiciled in Australia, it is likely that any action would be taken in the Australian courts in relation to litigation or by the ASIC, in relation to any regulatory enforcement action. As Cboe Japan is domiciled in Japan, it is likely that any action would be taken in the Japanese courts in relation to litigation or by the JFSA or the JSDA in relation to any regulatory enforcement action. As MATCHNow and Cboe Canada are domiciled in Canada, it is likely that any action would be taken in the Canadian courts in relation to litigation or by the OSC and/or CIRO in relation to any regulatory enforcement action.

Cboe Digital has committed to securely store all digital assets it holds on behalf of users. As such, Cboe Digital may be liable to its users for losses arising from theft or loss of user private keys. Cboe Digital has no reason to believe it will incur any expense associated with such potential liability because (i) it has no known or historical experience of claims to use as a basis of measurement, (ii) it accounts for and continually verifies the amount of digital assets within its control, and (iii) it has established security around custodial private keys to minimize the risk of theft or loss. There were no loss events impacting safeguarded assets caused by the theft or loss of digital asset user private keys as of September 30, 2023. As such, the Company had not recorded a liability at September 30, 2023.

The Company is also currently a party to various other legal proceedings in addition to those already mentioned. Management does not believe that the likely outcome of any of these other reviews, inspections, investigations or other legal proceedings is expected to have a material impact on the Company’s financial position, results of operations, liquidity or capital resources.

See also Note 19 (“Income Taxes”).

Contractual Obligations

The Company has contractual obligations related to licensing agreements with various licensors, some of which included fixed fees and/or variable fees calculated using agreed upon contracted rates and reported cleared volumes. Certain licensing agreements contain annual minimum fee requirements that total between $15.0 and $16.1 million each year for the next five years. Cboe Canada has purchase obligations primarily related to software development activities of $1.3 million in total over the next three years.

The Company operates six reportable business segments: Options, North American Equities, Europe and Asia Pacific, Futures, Global FX, and Digital which is reflective of how the Company's chief operating decision-maker reviews and operates the business, as discussed in Note 1 (“Organization and Basis of Presentation”). Segment performance is primarily evaluated based on operating income (loss). The Company’s chief operating decision-maker does not use segment-level assets or income and expenses below operating income (loss) as key performance metrics; therefore, such information is not presented below. The Company has aggregated all of its corporate costs, as well as other business ventures, within the Corporate Items and Eliminations totals based on the decision that those activities should not be used to evaluate the operating performance of the segments; however, operating expenses that relate to activities of a specific segment have been allocated to that segment.

Options. The Options segment includes options on market indices (“index options”), as well as on the stocks of individual corporations (“equity options”), and options on ETPs, such as exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”), which are “multi-listed” options and listed on a non-exclusive basis. These options are eligible to trade, as applicable, on Cboe Options, C2, BZX, EDGX, and/or other U.S. national security exchanges. Cboe Options is the Company’s primary options market and offers trading in listed options through a single system that integrates electronic trading and traditional open outcry trading on the Cboe Options trading floor in Chicago. C2 Options, BZX Options, and EDGX Options are all-electronic options exchanges, and typically operate with different market models and fee structures than Cboe Options. The Options segment also includes applicable market data fees generated from the consolidated tape plans, the licensing of proprietary options market data, index licensing, and access and capacity services.

North American Equities. The North American Equities segment includes listed U.S. equities and ETP transaction services that occur on fully electronic exchanges owned and operated by BZX, BYX, EDGX, and EDGA, equities transactions that occur on the BIDS Trading platform, and Canadian equities and other transaction services that occur on or through the MATCHNow ATS and Cboe Canada. The North American Equities segment also includes listing services on Cboe Canada Exchange, ETP listings on BZX, the Cboe Global Markets, Inc. common stock listing, applicable market

51

data fees generated from the consolidated tape plans, the licensing of proprietary equities market data, routing services, and access and capacity services.

Europe and Asia Pacific. The Europe and Asia Pacific segment includes the pan-European listed equities and derivatives transaction services, ETPs, exchange-traded commodities, and international depository receipts that are hosted on MTFs operated by Cboe Europe Equities (Cboe Europe and Cboe NL equities exchanges) and Cboe Europe Derivatives (“CEDX”). It also includes the ETP listings business on RMs and clearing activities of Cboe Clear Europe, as well as the equities transaction services of Cboe Australia and Cboe Japan, operators of trading venues in Australia and Japan, respectively. Cboe Europe operates lit and dark books, a periodic auctions book, and Cboe BIDS Europe, a Large-in-Scale (“LIS”) trading negotiation facility for UK symbols. Cboe NL, launched in October 2019 and based in Amsterdam, operates similar business functionality to that offered by Cboe Europe, and provides for trading only in European Economic Area (“EEA”) symbols. Cboe Europe Derivatives, a pan-European derivatives platform launched in September 2021, offers futures and options based on Cboe Europe equity indices. This segment also includes Cboe Europe, Cboe NL, CEDX, Cboe Australia and Cboe Japan revenue generated from the licensing of proprietary market data and from access and capacity services.

Futures. The Futures segment includes transaction services provided by CFE, a fully electronic futures exchange, which includes offerings for trading of VIX futures and other futures products, the licensing of proprietary market data, as well as access and capacity services.

Global FX. The Global FX segment includes institutional FX trading services that occur on the Cboe FX fully electronic trading platform, non-deliverable forward FX transactions (“NDFs”) offered for execution on Cboe SEF and Cboe Swiss, as well as revenue generated from the licensing of proprietary market data and from access and capacity services. The segment includes transaction services for U.S. government securities executed on the Cboe Fixed Income fully electronic trading platform.

Digital. The Digital segment includes Cboe Digital, an operator of a U.S. based digital asset spot market and a regulated futures exchange, and Cboe Clear Digital, a regulated clearinghouse, as well as revenue generated from the licensing of proprietary market data and from access and capacity services.

Executive Transitions

On July 6, 2023, Brian Schell, former Executive Vice President, Chief Financial Officer and Treasurer, announced his departure from the Company to pursue a new professional opportunity outside of the exchange industry. Jill Griebenow, Senior Vice President and Chief Accounting Officer, was appointed to serve as Executive Vice President, Chief Financial Officer, Treasurer and Chief Accounting Officer effective July 10, 2023, and currently serves as Executive Vice President, Chief Financial Officer and Chief Accounting Officer.

On September 18, 2023, Edward T. Tilly, former Chief Executive Officer of the Company, resigned and voluntarily terminated his employment with the Company without Good Reason (as defined under his existing employment agreement with the Company), effective as of September 18, 2023 (the “Effective Date”). Mr. Tilly also resigned as Chairman of the Company’s Board of Directors, effective as of the Effective Date. Mr. Tilly’s resignation followed the conclusion of an investigation led by the Board of Directors and outside independent counsel that was launched in late August 2023. The Board of Directors determined that Mr. Tilly did not disclose personal relationships with colleagues, which violated the Company’s policies and stands in stark contrast to the Company’s values. The conduct was not related to and does not impact the Company’s strategy, financial performance, technology and market operations, financial reporting or internal controls over financial reporting. Following Mr. Tilly’s resignation, Fredric J. Tomczyk, an existing director of the Company, was appointed as Chief Executive Officer of the Company, effective as of the Effective Date. As a result of Mr. Tomczyk’s appointment as Chief Executive Officer, Mr. Tomczyk stepped down from the Board of Directors’ Compensation Committee and Finance and Strategy Committee as of the Effective Date. Also as of the Effective Date, William M. Farrow III was appointed as non-executive Chairman of the Board of Directors (replacing his prior role as Lead Director of the Board of Directors).

General Factors Affecting Results of Operations

In broad terms, our business performance is impacted by a number of drivers, including macroeconomic events affecting the risk and return of financial assets, investor sentiment, the regulatory environment for capital markets, geopolitical events, tax policies, central bank policies and changing technology, particularly in the financial services

52

industry. We believe our future revenues and net income will continue to be influenced by a number of domestic and international economic trends, including:

● trading volumes on our proprietary products such as VIX options and futures and SPX options;

● trading volumes in listed equity securities, options, futures, and ETPs in North America, Europe, and Asia Pacific, clearing volumes in listed equity securities and ETPs in Europe, volumes in listed equity options, volumes in digital assets, and volumes in institutional FX trading; 

● the demand for and pricing structure of the U.S. tape plan market data distributed by the Securities Information Processors (“SIPs”), which determines the pool size of the industry market data fees we receive based on our market share;

● consolidation and expansion of our customers and competitors in the industry;

● the demand for information about, or access to, our markets and products, which is dependent on the products we trade, our importance as a liquidity center, quality and integrity of our proprietary indices, and the quality and pricing of our data and access and capacity services; 

● continuing pressure in transaction fee pricing due to intense competition in the North American, European, and Asia Pacific markets;

● significant fluctuations in foreign currency translation rates or weakened value of currencies; and

● regulatory changes and obligations relating to market structure, digital assets and increased capital requirements, and those which affect certain types of instruments, transactions, products, pricing structures, capital market participants or reporting or compliance requirements.

A number of significant structural, political and monetary issues, global conflicts continue to confront the global economy, and instability could continue, resulting in an increased or subdued level of inflation, market volatility, potential recessions, supply chain constraints, changes in trading volumes and greater uncertainty, inflationary increases in our expenses, such as compensation inflation, and increased costs and uncertainties related to CAT and the ability to collect on the promissory notes related to the funding of CAT may have an adverse effect on our financial results.

Components of Revenues

The components of revenues are described below:

Cash and Spot Markets

Revenue aggregated into cash and spot markets includes associated transaction and clearing fees, the portion of market data fees relating to associated U.S. tape plan market data fees, associated regulatory fees, and associated other revenue from the Company’s North American Equities, Europe and Asia Pacific, Global FX, and Digital segments.

Data and Access Solutions

Revenue aggregated into data and access solutions includes access and capacity fees, proprietary market data fees, and associated other revenue across the Company’s six segments.

Derivatives Markets

Includes associated transaction and clearing fees, the portion of market data fees relating to associated U.S. tape plan market data fees, associated regulatory fees, and associated other fees from the Company’s Options, Futures, Europe and Asia Pacific, and Digital segments.

Components of Cost of Revenues

Liquidity Payments

Liquidity payments are directly correlated to the volume of securities traded on our markets. As stated above, we record the liquidity rebates paid to market participants providing liquidity, in the case of C2, BZX, EDGX, and Cboe Europe Equities and Derivatives, and Cboe Digital, as cost of revenue. BYX and EDGA offer a pricing model where we rebate liquidity takers for executing against an order resting on our book, which is also recorded as a cost of revenues.

53

Routing and Clearing

Various rules require that U.S. options and equities trade executions occur at the National Best Bid and Offer displayed by any exchange. Linkage order routing consists of the cost incurred to provide a service whereby Cboe equities and options exchanges deliver orders to other execution venues when there is a potential for obtaining a better execution price or when instructed to directly route an order to another venue by the order provider. The service affords exchange order flow providers an opportunity to obtain the best available execution price and may also result in cost benefits to those clients. Such an offering improves our competitive position and provides an opportunity to attract orders which would otherwise bypass our exchanges. We utilize third-party brokers or our broker-dealer, Cboe Trading, to facilitate such delivery. Also included within routing and clearing are the Order Management System and Execution Management System (“OMS” and “EMS”, respectively) fees incurred for U.S. Equities Off-Exchange order execution, as well as settlement costs incurred for the settlement process executed by Cboe Clear Europe and Cboe Clear Digital.

Section 31 Fees

Exchanges under the authority of the SEC (Cboe Options, C2, BZX, BYX, EDGX, and EDGA as well as CFE to the extent that CFE offers trading in security futures products) are assessed fees pursuant to the Exchange Act designed to recover the costs to the U.S. government of supervision and regulation of securities markets and securities professionals. We treat these fees as a pass-through charge to customers executing eligible listed equities and listed equity options trades. Accordingly, we recognize the amount that we are charged under Section 31 as a cost of revenues and the corresponding amount that we charge our customers as regulatory transaction fees revenue. Since the regulatory transaction fees recorded in revenues are equal to the Section 31 fees recorded in cost of revenues, there is no impact on our operating income. Cboe Trading, Cboe Europe, Cboe NL, BIDS, MATCHNow, Cboe FX, Cboe Australia, Cboe Japan, Cboe Digital, and Cboe Canada are not U.S. national securities exchanges, and accordingly are not charged Section 31 fees.

Royalty Fees and Other Cost of Revenues

Royalty fees primarily consist of license fees paid by us for the use of underlying indices in our proprietary products usually based on contracts traded. The Company has licenses with the owners of the S&P 500 Index, S&P 100 Index and certain other S&P indices, FTSE Russell indices, the DJIA, MSCI, and certain other index products. This category also includes fees related to the dissemination of market data related to S&P indices and other products through Cboe Global Indices Feed (“CGIF”).

Other cost of revenues primarily consists of interest expense from clearing operations, electronic access permit fees and other miscellaneous costs associated with other revenue.

Components of Operating Expenses

Compensation and Benefits

Compensation and benefits represent our largest expense category and tend to be driven by our staffing requirements, financial performance, and the general dynamics of the employment market. Stock-based compensation is a non-cash expense related to employee equity awards. Stock-based compensation can vary depending on the quantity and fair value of the award on the date of grant and the related service period.

Depreciation and Amortization

Depreciation and amortization expense results from the depreciation of long-lived assets purchased, the amortization of purchased and internally developed software, and the amortization of intangible assets.

Technology Support Services

Technology support services consists primarily of costs related to the maintenance of computer equipment supporting our system architecture, circuits supporting our wide area network, support for production software, operating system license and support fees, fees paid to information vendors for displaying data and off-site system hosting fees.

54

Professional Fees and Outside Services

Professional fees and outside services consist primarily of consulting services, which include supplemental staff activities primarily related to systems development and maintenance, legal, regulatory and audit, and tax advisory services, as well as stock-based compensation related to director awards.

Travel and Promotional Expenses

Travel and promotional expenses primarily consist of advertising, costs for special events, sponsorship of industry conferences, options education seminars and travel-related expenses.

Facilities Costs

Facilities costs primarily consist of expenses related to owned and leased properties including rent, maintenance, utilities, real estate taxes and telecommunications costs.

Acquisition-Related Costs

Acquisition-related costs relate to acquisitions and other strategic opportunities. The acquisition-related costs include fees for investment banking advisors, lawyers, accountants, tax advisors, public relations firms, severance and retention costs, capitalized software and facilities, and other external costs directly related to mergers and acquisitions.

Goodwill Impairment

Goodwill impairment consists of charges to impair goodwill of our reporting units if the carrying value exceeds the implied fair value.

Other Expenses

Other expenses represent costs necessary to support our operations that are not already included in the above categories, including, but not limited to the impairment of digital assets held presented in intangible assets, net as part of the ordinary operations of the Digital segment and changes in contingent consideration.

Non-Operating (Expenses) Income

Income and expenses incurred through activities outside of our core operations are considered non-operating and are classified as other (expense) income. These activities primarily include interest earned on the investing of excess cash, interest expense related to outstanding debt facilities, income and unrealized gains and losses related to investments held in a trust for the Company’s non-qualified retirement and benefit plans, realized gains and losses related to the Company’s previously held minority investments, income earned related to the Company’s minority investments, equity earnings or losses from our investments in other business ventures, impairment of the Company’s investments, investment establishment costs associated with new business ventures, and loan forgiveness provided under the SBA’s PPP. See Note 10 (“Debt”) for additional information regarding the PPP.

Financial Summary

The following are summaries of changes in financial performance and include certain non-GAAP financial measures. Management uses these non-GAAP measures internally in conjunction with GAAP measures to help evaluate our performance and to help make financial and operational decisions. These non-GAAP financial measures assist management in comparing our performance on a consistent basis for purposes of business decision making by removing the impact of certain items management believes do not reflect our underlying operations.

We believe our presentation of these measures provides investors with greater transparency into financial measures used by management and is useful to investors for period-to-period comparisons of our ongoing operating performance.

These non-GAAP financial measures are not presented in accordance with, or as an alternative to, GAAP financial measures and may be calculated differently from non-GAAP measures used by other companies, which reduces their usefulness as comparative measures. We encourage analysts, investors and other interested parties to use these non-

55

GAAP measures as supplemental information to the GAAP financial measures included herein, including our condensed consolidated financial statements, to enhance their analysis and understanding of our performance and in making comparisons. Please see the footnotes below for definitions, additional information, and reconciliations from the closest GAAP measure.

(1) Organic net revenue is defined as revenues less cost of revenues excluding revenues less cost of revenues of any acquisition that has been owned for less than one year. Revenues from acquisitions that have been owned at least one year are considered organic and are no longer excluded from organic net revenue from either period for comparative purposes. Organic net revenue does not represent, and should not be considered as, an alternative to revenues less cost of revenues, or net revenue, as determined in accordance with GAAP. We have presented organic net revenue because we consider it an important supplemental measure of our performance and we use it as the basis for monitoring our operating financial performance before the effects of acquisitions. We also believe that it is frequently used by analysts, investors and other interested parties in the evaluation of companies. We believe that investors may find this non-GAAP measure useful in evaluating our performance compared to that of peer companies in our industry. Other companies may calculate organic net revenue differently than we do. Organic net revenue has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP.

(2) EBITDA is defined as income or loss before interest, income taxes, depreciation and amortization. Adjusted EBITDA is defined as EBITDA before acquisition-related costs, impairment of investment, gain on investment, investment establishment costs, impairment of goodwill, loan forgiveness, and income from investments. EBITDA and adjusted EBITDA do not represent, and should not be considered as, alternatives to net income or loss as determined in accordance with GAAP. We have presented EBITDA and adjusted EBITDA because we consider them important supplemental measures of our performance and believe that they are frequently used by analysts, investors and other interested parties in the evaluation of companies. In addition, we use adjusted EBITDA as a measure of operating performance for preparation of our forecasts and evaluating our leverage ratio for the debt to earnings covenant included in our outstanding credit facility. Other companies may calculate EBITDA and adjusted EBITDA differently than we do. EBITDA and adjusted EBITDA have limitations as analytical tools, and you should not consider them in isolation or as substitutes for analysis of our results as reported under GAAP.

(3) EBITDA margin represents EBITDA divided by revenues less cost of revenues.

(4) Adjusted EBITDA margin represents adjusted EBITDA divided by revenues less cost of revenues.

(5) Adjusted earnings is defined as net income or loss adjusted for amortization of purchased intangibles, acquisition-related costs, gain on investment, investment establishment costs, impairment of goodwill, loan forgiveness, income from investments, certain tax reserve changes, deferred tax re-measurements, and net income or loss allocated to participating securities, net of the income tax effects of these adjustments. Adjusted earnings does not represent, and should not be considered as, an alternative to net income or loss, as determined in accordance with GAAP. We have presented adjusted earnings because we consider it an important supplemental measure of our performance and we use it as the basis for monitoring our own core operating financial performance relative to other operators of exchanges. We also believe that it is frequently used by analysts, investors and other interested parties in the evaluation of companies. We believe that investors may find this non-GAAP measure useful in evaluating our performance compared to that of peer companies in our industry. Other companies may calculate adjusted earnings differently than we do. Adjusted earnings has limitations as an analytical tool, and you should not consider it in isolation or as a substitute for analysis of our results as reported under GAAP.

(6) Adjusted diluted earnings per share represents adjusted earnings divided by diluted weighted average shares outstanding.

Revenues

Total revenues for the three months ended September 30, 2023 decreased $84.7 million, or 9%, compared to the same period in 2022 primarily due to a decrease in cash and spot markets revenue, driven by a decrease in the Section 31 fee rate following a rate change in February 2023, coupled with a decline in volumes traded on the U.S. Equities exchanges, partially offset by an increase in access and capacity fees and proprietary market data across segments. Total revenues for the nine months ended September 30, 2023 decreased $149.0 million, or 5%, compared to the same period in 2022 primarily due to a decrease in cash and spot markets revenue, driven by a decline in volumes traded on the U.S. Equities and European Equities exchanges, coupled with a decrease in the Section 31 fee rate, partially offset by an increase in derivatives markets revenue as a result of increased volumes traded on the Options exchanges and an increase in access and capacity fees and proprietary market data across segments.

Cash and Spot Markets

Cash and spot markets revenues less cost of revenues decreased for the three months ended September 30, 2023 compared to the same period in 2022 primarily due to decreases in transaction and clearing fees less liquidity payments and routing and clearing costs (“net transaction and clearing fees”) in the North American Equities and Europe and Asia Pacific segments. Net transaction and clearing fees decreased primarily due to an 8% decrease in total touched shares on the U.S. Equities exchanges and a 17% decrease in European Equities matched ADNV.

Cash and spot markets revenue decreased for the nine months ended September 30, 2023 compared to the same period in 2022 primarily due to decreases in net transaction and clearing fees in the North American Equities and Europe and Asia Pacific segments, coupled with a decrease in industry market data fees.

Compensation and Benefits

Compensation and benefits decreased for the three months ended September 30, 2023 compared to the same period in 2022 primarily due to a $13.6 million decrease in bonuses, and a $5.3 million decrease in equity compensation as a result of the aforementioned executive departures, partially offset by a $12.1 million increase in salaries driven by increased headcount. Compensation and benefits increased for the nine months ended September 30, 2023 compared to the same period in 2022 primarily due to a $40.6 million increase in salaries driven by merit and cost-of-living increases and increased headcount excluding acquisitions, coupled with a $5.5 million increase related to the acquisitions of Cboe Digital and Cboe Canada. Additionally, there was a $12.0 million increase in benefits primarily due to an increase in the market value of the non-qualified deferral plan and increases in payroll benefits, taxes, and employer contribution as a result of the aforementioned increase in salaries. The increases were partially offset by a $15.3 million decrease in bonuses.

Depreciation and Amortization

Depreciation and amortization decreased for the three and nine months ended September 30, 2023 compared to the same periods in 2022 due to a decline in amortization under the discounted cash flow method for the intangibles acquired in the Merger, partially offset by an increase in depreciation and amortization expenses related to the acquisition of Cboe Canada.

Interest Expense

Interest expense decreased for the three months ended September 30, 2023 compared to the same period in 2022 primarily due to repayments on the Term Loan in the third and fourth quarter of 2022, as well as payments made in the second and third quarter of 2023, coupled with a decrease in interest expense related to the Cboe Clear Europe Credit Facility, which was amended and restated in June 2023.

Interest expense increased for the nine months ended September 30, 2023 compared to the same period in 2022 primarily due to additional borrowings on the Term Loan in the second quarter of 2022, as well as an increase in the

69

SOFR rate, partially offset by a decrease in interest expense related to the Cboe Clear Europe Credit Facility, which was amended and restated in June 2023.

Interest Income

Interest income increased for the three and nine months ended September 30, 2023 compared to the same periods in 2022 primarily due to increases in interest rates in 2023.

Other Income (Expense), Net

Net other income increased for the three months ended September 30, 2023 compared to the same period in 2022 primarily due to a $10.8 million unrealized gain on the Company’s investment in 7Ridge Fund (which owns Trading Technologies) recorded in the third quarter of 2023.

Net other income increased for the nine months ended September 30, 2023 compared to the same period in 2022 primarily due to a $33.7 million unrealized gain on the Company’s investment in 7Ridge Fund and $2.1 million in dividend income from the Company’s minority ownership of Vest, which were both recorded in 2023, coupled with a $10.6 million impairment adjustment of the Company’s investment in American Financial Exchange, LLC and a $3.1 million loss related to the Company’s investment in 7Ridge Fund, which were both recorded in 2022 and did not recur in 2023, partially offset by a $7.5 million gain on the Company’s previous minority ownership of Cboe Digital, which was recorded in 2022 and did not recur in 2023.

Income Before Income Tax Provision

As a result of the above, income before income tax provision for the three months ended September 30, 2023 was $270.1 million, compared to income before income tax provision of $229.0 million for the same period in 2022, an increase of $41.1 million.

As a result of the above, income before income tax provision for the nine months ended September 30, 2023 was $760.1 million, compared to income before income tax provision of $197.1 million for the same period in 2022, an increase of $563.0 million.

Income Tax Provision

The effective tax rate from continuing operations was 22.9% and 34.4% for the three months ended September 30, 2023 and 2022, respectively, and 27.7% and 61.8% for the nine months ended September 30, 2023 and 2022, respectively.

The effective tax rate for the three months ended September 30, 2023 is lower than it was for the same period in 2022 primarily as a result of the release of income tax reserves associated with penalties and interest thereon as a result of the remeasurement of tax reserves related to Section 199 deduction claims which were in dispute with the IRS. The Company has reached a settlement with the IRS under which the Company has conceded all the claimed Section 199 deductions in exchange for the IRS’s concession of penalties asserted on the Company’s Section 199 deductions. Although the parties had not completed all legal procedures to affect the settlement at September 30, 2023, the IRS provided a written response agreeing to these terms prior to September 30, 2023. The Company accordingly remeasured its Section 199 tax reserve liabilities and released its reserves associated with penalties and interest thereon for its Section 199 claims as of September 30, 2023. Subsequent to September 30, 2023, the parties have completed all legal procedures to affect the settlement.

The lower effective tax rate for the nine months ended September 30, 2023 compared to the same period in 2022 is primarily due to the circumstances outlined above, coupled with lower income before income tax provision for the nine months ended September 30, 2022 as a result of the Cboe Digital goodwill impairment.

Revenues less cost of revenues decreased $3.5 million for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022 primarily due to a decrease in net transaction and clearing fees driven by a 16% decrease in total touched shares on the U.S. Equities exchanges, coupled with a decline in market data fees as a result of a decrease in U.S. tape plan revenue due to a 1% decline in market share on the U.S. Equities exchanges, partially offset by an increase in revenues less costs of revenues attributable to Cboe Canada. For the nine months ended September 30, 2023, operating income for the North American Equities segment decreased $23.2 million compared to the nine months ended September 30, 2022 due to an increase in operating expenses and a decrease in revenues less cost of revenues. Operating expenses increased $19.7 million for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022 primarily due to increases in compensation and benefits, travel and promotional expenses, technology support services, and professional fees and outside services, partially offset by a decrease in acquisition-related costs and depreciation and amortization.

Liquidity and Capital Resources

Below are charts that reflect elements of our capital allocation:

We expect our cash on hand at September 30, 2023 and other available resources, including cash generated from operations, to be sufficient to continue to meet our cash requirements for the foreseeable future. In the near term, we expect that our cash from operations and availability under the Revolving Credit Facility and potentially participating in future financing transactions to obtain additional capital will meet our cash needs to fund our operations, capital expenditures, interest payments on debt, debt repayments, such as under the Term Loan Agreement, which matures on December 15, 2023, any dividends, potential strategic acquisitions, opportunities for common stock repurchases under the previously announced program, and payouts related to the unfavorable decision in the Section 199 litigation. See Note 10 (“Debt”) of the condensed consolidated financial statements for further information.

Cboe Clear Europe also has a €1.25 billion committed syndicated multicurrency revolving and swingline credit facility agreement with Cboe Clear Europe as borrower and the Company as guarantor of scheduled interest and fees on borrowings (but not the principal amount of any borrowings) (the “Facility”). The Facility is available to be drawn by Cboe Clear Europe towards (a) financing unsettled amounts in connection with the settlement of transactions in securities and other items processed through Cboe Clear Europe’s clearing system and (b) financing any other liability or liquidity requirement of Cboe Clear Europe incurred in the operation of its clearing system. Borrowings under the Facility are secured by cash, eligible bonds and eligible equity assets deposited by Cboe Clear Europe into secured accounts. As a result, should the Facility be drawn by Cboe Clear Europe it could potentially impact Cboe Clear Europe’s liquidity, and we can give no assurance that this Facility will be sufficient to meet all of such obligations or sufficiently mitigate Cboe Clear Europe’s liquidity risk to meet its payment obligations when due. Additionally, a default of the Facility may allow lenders, under certain circumstances, to accelerate any related drawn amounts and may result in the acceleration of the Company’s other outstanding debt to which a cross-acceleration or cross-default provision applies, which may limit the Company’s liquidity, business and financing activities. The Facility was amended on June 29, 2023, which extended the term of the facility through June 28, 2024.

Our long-term cash needs will depend on many factors, including an introduction of new products, enhancements of current products, the geographic mix of our business and any potential acquisitions. We believe our cash from operations and the availability under our Revolving Credit Facility will meet any long-term needs unless a significant acquisition or acquisitions are identified, in which case we expect that we would be able to borrow the necessary funds and/or issue additional shares of our common stock to complete such acquisition(s).

78

Cash and cash equivalents include cash in banks and all non-restricted, highly liquid investments with original maturities of three months or less at the time of purchase. Cash and cash equivalents as of September 30, 2023 decreased $29.6 million from December 31, 2022 primarily due to principal payments of current portion of long-term debt, outflows from cash dividends, share repurchases, purchases of available-for-sale financial investments, and contributions to investments, partially offset by the results of operations. See “Cash Flow” below for further discussion.

Our cash and cash equivalents held outside of the United States in various foreign subsidiaries totaled $220.2 million as of September 30, 2023. The remaining balance was held in the United States and totaled $182.9 million as of September 30, 2023. The majority of cash held outside the United States is available for repatriation, but under current law, could subject us to additional United States income taxes, less applicable foreign tax credits.

Our financial investments include deferred compensation plan assets, as well as investments with original or acquired maturities longer than three months, but that mature in less than one year from the balance sheet date and are recorded at fair value. As of September 30, 2023 and December 31, 2022, financial investments consisted of U.S. Treasury securities and deferred compensation plan assets.

Cash Flow

The following table summarizes our cash flow data for the nine months ended September 30, 2023 and 2022, respectively (in millions):

Customer bank deposits (included in margin deposits, clearing funds, and interoperability funds)		15.8		18.9
Total	$	1,731.7	$	1,386.5

Net Cash Flows Provided by Operating Activities

During the nine months ended September 30, 2023, net cash provided by operating activities was $715.2 million higher than net income. The variance is primarily attributable to the change in restricted cash and cash equivalents, driven by margin deposits, clearing funds, and interoperability funds related to Cboe Clear Europe of $785.6 million and depreciation and amortization of $120.0 million, partially offset by the change in the Section 31 fees payable of $(135.5) million, and the change in accounts payable and accrued liabilities of $(42.5) million for the nine months ended September 30, 2023.

Net cash flows provided by operating activities were $1,264.6 million and $794.7 million for the nine months ended September 30, 2023 and 2022, respectively. The change in net cash flows provided by operating activities was primarily due to the change in restricted cash and cash equivalents and customer bank deposits driven by margin deposits, clearing funds, and interoperability funds related to Cboe Clear Europe, the change in net income, and the change in benefit for deferred income taxes, partially offset by the change in goodwill impairment, the change in Section 31 fees

79

payable, the change in accounts payable and accrued liabilities, and the change in unrecognized tax benefits for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.

Net Cash Flows Used in Investing Activities

Net cash flows used in investing activities were $16.9 million and $744.6 million for the nine months ended September 30, 2023 and 2022, respectively. The variance is primarily due to the change in acquisitions, net of cash acquired and proceeds from maturities of available-for-sale financial investments, partially offset by the change in contributions to investments and purchases of available-for-sale financial investments for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.

Net Cash Flows (Used in) Provided by Financing Activities

Net cash flows (used in) provided by financing activities were $(513.6) million and $274.7 million for the nine months ended September 30, 2023 and 2022, respectively. The variance is primarily attributable to proceeds from the long-term debt issuance of $663.6 million in the nine months ended September 30, 2022, that did not recur in 2023, and principal payments of current portion of debt, partially offset by the change in payments of contingent consideration related to acquisitions for the nine months ended September 30, 2023 compared to the nine months ended September 30, 2022.

Financial Assets

The following summarizes our financial assets, excluding margin deposits, clearing funds, and interoperability funds as of September 30, 2023 and December 31, 2022 (in millions):

	September 30,		December 31,
	2023		2022
Cash and cash equivalents	$	403.1	$	432.7
Financial investments		34.0		91.7
Less deferred compensation plan assets		(33.5)		(27.5)
Less cash collected for Section 31 fees		—		(93.7)
Adjusted cash (1)	$	403.6	$	403.2

(1) Adjusted cash is a non-GAAP measure and represents cash and cash equivalents plus financial investments, minus deferred compensation plan assets and cash collected for Section 31 fees. We have presented adjusted cash because we consider it an important supplemental measure of our liquidity and believe that it is frequently used by analysts, investors and other interested parties in the evaluation of companies.

Debt

The following summarizes our debt obligations as of September 30, 2023 and December 31, 2022 (in millions):

	September 30,		December 31,
	2023		2022
Term Loan Agreement	$	75.0	$	305.0
3.650% Senior Notes		650.0		650.0
1.625% Senior Notes		500.0		500.0
3.000% Senior Notes		300.0		300.0
Less unamortized discount and debt issuance costs		(11.4)		(13.0)
Total debt	$	1,513.6	$	1,742.0

As of September 30, 2023 and December 31, 2022, we were in compliance with the covenants of our debt agreements.

In addition to the debt outstanding, as of September 30, 2023, we had an additional $400.0 million available through our revolving credit facility, with the ability to borrow another $200.0 million by increasing the commitments under the facility, subject to the agreement of the applicable lenders. Together with adjusted cash, we had $857.9 million available to fund our operations, capital expenditures, potential acquisitions, debt repayments and any dividends, net of minimum regulatory capital requirements of $145.7 million as of September 30, 2023.

Dividends

The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company's Board of Directors and may be affected by various factors, including our earnings, financial condition, capital requirements, level of indebtedness and other considerations our Board of Directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, our ability to pay dividends.

Share Repurchase Program

In 2011, the Board of Directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and subsequently approved additional authorizations for a total authorization of $1.6 billion. The program permits the Company to purchase shares through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation. Share repurchases are repurchased to the Company’s Treasury stock and ultimately retired or they are available to be redistributed.

On August 16, 2022, President Biden signed into law H.R. 5376 (commonly known as the Inflation Reduction Act of 2022 or simply the “IRA”). Tax measures contained in the IRA include, among other items, a new excise tax of 1% on repurchases of stock by domestic corporations with stock traded on established securities markets. The amount on which the tax is imposed is reduced by the value of any stock issued by such corporation during the tax year and the tax generally applies to stock buy-back transactions occurring after December 31, 2022. This new tax is not expected to result in a material impact to the Company.

The Company did not repurchase shares under the Company’s share repurchase program during the three months ended September 30, 2023. Since inception of the program through September 30, 2023, the Company has repurchased 19,576,581 shares of common stock at an average cost per share of $72.03, totaling $1.4 billion.

As of September 30, 2023, the Company had $139.8 million of availability remaining under its existing share repurchase authorizations.

Commercial Commitments and Contractual Obligations

As of September 30, 2023, our commercial commitments and contractual obligations included operating leases, data and telecommunications agreements, equipment leases, our long-term debt outstanding, contingent considerations, software development activities and other obligations. See Note 21 (“Commitments, Contingencies, and Guarantees”) to the condensed consolidated financial statements for a discussion of commitments and contingencies, Note 10 (“Debt”) for a discussion of the outstanding debt, Note 12 (“Clearing Operations”) for information on Cboe Clear Europe and Cboe Digital’s clearinghouse exposure guarantees, and Note 22 (“Leases”) for discussion on operating leases and equipment leases.

Guarantees

We use Wedbush and Morgan Stanley to clear our routed equities transactions for our U.S. Equities exchanges. Wedbush and Morgan Stanley guarantee the trade until one day after the trade date, after which time the National Securities Clearing Corporation (“NSCC”) provides a guarantee. The BIDS Trading ATS platform delivers matched trades to BofA Securities, Inc. (“BOA”), which delivers the matched trades to the NSCC. BOA guarantees the trade until one day after the trade date, after which time the NSCC provides a guarantee.

In the case of failure to perform on the part of BOA on transactions for the BIDS Trading ATS platform, BIDS has obligations to the counterparties to satisfy the trades. OCC acts as a central counterparty on all transactions in listed equity options in our Options segment, and as such, guarantees clearance and settlement of all of our options transactions. We believe that any potential requirement for us to make payments under these guarantees is remote and accordingly, have not recorded any liability in the condensed consolidated financial statements for these guarantees.

Critical Accounting Estimates

The preparation of condensed consolidated financial statements in conformity with U.S. GAAP requires our management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of the amounts of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ materially from those estimates. On an ongoing basis, the Company evaluates its estimates, including those related to areas that require a significant level of judgment or are otherwise subject to an inherent degree of uncertainty. The Company bases its estimates on historical experience, observance of trends in particular areas, information available from outside sources and various other assumptions that are believed to be reasonable under the circumstances. Information from these sources form the basis for making judgments about the carrying values of assets and liabilities that may not be readily apparent from other sources.

In the nine months ended September 30, 2023, there were no significant changes to our critical accounting estimates from those disclosed in the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our 2022 Annual Report on Form 10-K.

Item 3. Quantitative and Qualitative Disclosures about Market Risk

As a result of our operating activities, we are exposed to market risks such as foreign currency exchange rate risk, equity risk, credit risk, interest rate risk, and liquidity risk. We have implemented policies and procedures to measure, manage and monitor and report risk exposures, which are reviewed regularly by management and our Board of Directors.

Foreign Currency Exchange Rate Risk

Our operations in Europe, Canada and Asia are subject to increased currency translation risk as revenues and expenses are denominated in foreign currencies, primarily the British pound, Euro, Canadian dollar, Australian dollar, and Japanese Yen. We also have de minimis exposure to other foreign currencies, including the Singapore dollar, Philippine Peso, Hong Kong dollar, Swiss Franc, and Swedish Krona.

82

For the three and nine months ended September 30, 2023, our exposure to foreign-denominated revenues less cost of revenues and expenses is presented by primary foreign currency in the following table (in millions, except percentages):

	Three Months Ended									Nine Months Ended

Equity Risk

Our investment in European, Canadian, and Asia Pacific operations is exposed to volatility in currency exchange rates through translation of our net assets or equity to U.S. dollars. The assets and liabilities of our European businesses are denominated in British pounds or Euros. The assets and liabilities of our Canadian businesses are denominated in Canadian dollars. The assets and liabilities of our Asia Pacific businesses are denominated in Hong Kong dollars, Australian dollars, Japanese Yen, Philippine Pesos, or Singapore dollars. Fluctuations in currency exchange rates may create volatility in our reported results as we are required to translate foreign currency reported statements of financial condition and operational results into U.S. dollars for consolidated reporting. The translation of these non-U.S. dollar statements of financial condition into U.S. dollars for consolidated reporting results in a cumulative translation adjustment, which is recorded in accumulated other comprehensive income, net within stockholders' equity on our condensed consolidated balance sheets.

Our primary exposure to this equity risk as of September 30, 2023 is presented by foreign currency in the following table (in millions):

	British				Canadian
	Pounds (1)		Euros (1)		Dollars (1)
Net equity investment in Cboe Europe Equities and Derivatives, Cboe Clear Europe, MATCHNow, and Cboe Canada	$	647.5	$	168.3	$	519.9

(1) Converted to U.S. dollars using the foreign exchange rate of British pounds per U.S. dollar, Euros per U.S. dollar, and Canadian dollars per U.S. dollar, respectively, as of September 30, 2023.

Credit Risk

We are exposed to credit risk from third parties, including customers, counterparties and clearing agents. These parties may default on their obligations due to bankruptcy, lack of liquidity, operational failure or other reasons. We limit our exposure to credit risk by considering such risk when selecting the counterparties with which we make investments and execute agreements.

We do not have counterparty credit risk with respect to trades matched on our exchanges in the U.S., Canada, and Europe. With respect to listed equities, we deliver matched trades of our customers to the NSCC without taking on counterparty risk for those trades. NSCC acts as a central counterparty on all equity transactions occurring on BZX, BYX, EDGX and EDGA and, as such, guarantees clearance and settlement of all of our matched equity trades. Similarly, with respect to U.S. listed equity options and futures, we deliver matched trades of our customers to the OCC, which acts as a central counterparty on all transactions occurring on Cboe Options, C2, BZX, EDGX and CFE and, as such, guarantees clearance and settlement of all of our matched options and futures trades. With respect to Canadian equities, we deliver matched trades of our customers to The Canadian Depository for Securities, which acts as a central counterparty on all

83

transactions occurring on MATCHNow and, as such, guarantees clearance and settlement of all of our matched Canadian equities trades. The BIDS Trading ATS platform delivers matched trades to BOA, which delivers the matched trades to the NSCC. BOA guarantees the trade until one day after the trade date, after which time the NSCC provides a guarantee. Thus, BIDS Trading is potentially exposed to credit risk to the counterparty between the trade date and one day after the trade date in the event BOA fails. With respect to Australian equities and derivatives, we deliver matched trades of our customers to ASX Clear Pty Ltd and ASX Settlement Pty Ltd. ASX Clear Pty Ltd acts as a central counterparty on all transactions occurring on Cboe Australia and, as such, guarantees clearance and settlement on all of our matched trades in Australia. With respect to Japanese equities, we deliver matched trades of our customers to the Japanese Securities Clearing Corporation, which acts as a central counterparty on all transactions occurring on Cboe Japan and, as such, guarantees clearance and settlement on all of our matched trades in Japan.

With respect to orders Cboe Trading routes to other markets for execution on behalf of our customers, Cboe Trading is exposed to some counterparty credit risk in the case of failure to perform on the part of our clearing firms, Morgan Stanley or Wedbush. Morgan Stanley and Wedbush guarantee trades until one day after the trade date, after which time NSCC provides a guarantee. The BIDS Trading ATS platform delivers matched trades to BOA, which delivers the matched trades to the NSCC. Thus, Cboe Trading is potentially exposed to credit risk to the counterparty to a trade routed to another market center between the trade date and one day after the trade date in the event that Morgan Stanley or Wedbush fails. The BIDS Trading ATS platform is potentially exposed to counterparty credit risk on equities trades between the trade date and one day after the trade date in the event that BOA fails. We believe that any potential requirement for us to make payments under these guarantees is remote and accordingly, have not recorded any liability in the condensed consolidated financial statements for these guarantees.

Historically, we have not incurred any liability due to a customer’s failure to satisfy its contractual obligations as counterparty to a system trade. Credit difficulties or insolvency, or the perceived possibility of credit difficulties or insolvency, of one or more larger or more visible market participants could also result in market-wide credit difficulties or other market disruptions.

We do not have counterparty credit risk with respect to institutional spot FX trades occurring on our platform because Cboe FX is not a counterparty to any FX transactions. All transactions occurring on our platform occur bilaterally between two banks or prime brokers as counterparties to the trade. While Cboe FX does not have direct counterparty risk, Cboe FX may suffer a decrease in transaction volume if a bank or prime broker experiences an event that causes other prime brokers to decrease or revoke the credit available to the prime broker experiencing the event. Therefore, Cboe FX may have risk that is related to the credit of the banks and prime brokers that trade FX on the Cboe FX platform.

We also have credit risk related to transaction fees that are billed in arrears to customers on a monthly basis. Our potential exposure to credit losses on these transactions is represented by the receivable balances in our balance sheets. Our customers are financial institutions whose ability to satisfy their contractual obligations may be impacted by volatile securities markets.

The Company is exposed to further credit and investment risk through our clearing operations. Cboe Clear Europe holds material amounts of clearing participant collateral, both cash and non-cash deposits, which are held or invested primarily to provide security of capital while minimizing credit risk as well as liquidity and market risks. Cboe Digital holds amounts of clearing participant collateral including cash and digital assets, which are held primarily to provide security of capital while minimizing credit risk as well as custody, valuation and market risks. The following is a summary of the risks associated with these deposits and how these risks are mitigated:

● Credit Risk - The credit risk is predominantly in the event a clearing participant fails to meet a financial or contractual obligation and related to custodians and settlement banks. Cboe Clear Europe attempts to mitigate this risk through minimum participant requirements for clearing participants and monitoring their financial health. To cover potential loss to Cboe Clear Europe in the event of a clearing participant default, collateral is required from clearing participants. Besides potential defaults of clearing participants, the main credit risk faced by the clearinghouse is exposure to clearing participants when a trade fails to settle. To help mitigate this risk, a fail fee is charged to discourage late settlements. This fee covers Cboe Clear Europe’s costs but also acts as a deterrent as required by applicable settlement efficiency regulation. Cboe Clear Digital sets minimum financial requirements on custodian institutions and any clearing member that may expose the clearinghouse to credit risk. The financial strength of custodians and such clearing members are monitored routinely. Furthermore, Cboe Digital requires clearing members to post collateral (full or margined, depending on the product eligible for clearing) or other forms of financial guarantee and their trading activities are subject to pre-trade checks enforced by Cboe Digital Exchange and administered by Cboe Clear Digital. On June 5, 2023, the CFTC

84

approved an amended order of registration for Cboe Clear Digital to clear digital asset futures on a margined basis for futures commission merchants. The new products are intended to launch after the completion of internal and FCM readiness and the certification of required regulatory filings, including Cboe Digital Exchange self-certification to list and trade digital asset futures on a margined basis. As of September 30, 2023, Cboe Digital does not expect a material loss concerning credit risk on any member participant, custodian, or settlement bank.

● Liquidity Risk - Liquidity risk is the risk Cboe Clear Europe may not be able to meet its payment obligations in the right currency, in the right place and at the right time. To help mitigate this risk, Cboe Clear Europe monitors its liquidity requirements closely and maintains funds and assets in a manner which attempt to minimize the risk of loss or delay in the access by the clearinghouse to such funds and assets. For example, holding funds with a central bank where possible or making only short-term investments serves to help reduce liquidity risks. Liquidity is mainly required for securities settlement. The payment and settlement obligations generally stem from the function of Cboe Clear Europe as a cash equity clearinghouse: shares are bought and sold by clearing participants on a trading platform or OTC, and netted to settle two days later. During the settlement the actual payment for and delivery of the shares take place, this process requires intraday liquidity. If counterparties, which receive shares against payment, are unable to settle, an overnight liquidity need arises. The overnight liquidity is typically very short term, and is usually limited to a few days.

Cboe Clear Europe entered into a €1.25 billion committed syndicated multicurrency revolving and swingline credit facility that is available to be drawn by Cboe Clear Europe towards (a) financing unsettled amounts in connection with the settlement of transactions in securities and other items processed through Cboe Clear Europe’s clearing system and (b) financing any other liability or liquidity requirement of Cboe Clear Europe incurred in the operation of its clearing system, however we can give no assurance that this facility will be sufficient to meet all such obligations or sufficiently mitigate Cboe Clear Europe’s liquidity risk to meet its payment obligations when due.

● Custody Risk – Cboe Digital holds customer digital clearing assets through accounts with third party custodians and, in the case of hot and warm wallets, through self-custody. Cboe Digital’s custody strategy is designed to maximize liquidity and efficient access to assets by making those assets readily available. Cboe Digital monitors its cash and the digital asset balances it maintains with custodians. Digital assets require control of one or more unique public and private keys relating to the local or online digital wallet in which the digital assets are held. The networks require one or more private keys relating to a digital wallet to authorize a spending transaction. If private keys are lost or destroyed, this could prevent the ability to transfer the corresponding digital asset. Security breaches, computer malware, and computer hacking attacks have been a prevalent concern in digital asset markets. Cboe Digital has committed to securely store digital assets it holds on behalf of users. As such, Cboe Digital may be liable to its users for losses arising from theft or loss of user private keys. Cboe Digital has no reason to believe it will incur any expense associated with such potential liability because (i) it has no known or historical experience of claims to use as a basis of measurement, (ii) it accounts for and continually verifies the amount of digital assets within its control, and (iii) it has established security around custodial private keys to minimize the risk of theft or loss.

● Valuation Risk - Cboe Digital is exposed to risk with respect to digital asset prices and valuations which are largely based on the supply and demand for those digital assets in financial markets. Cboe Digital’s valuation governance framework includes numerous controls and other procedural safeguards that are intended to maximize the quality of fair value measurements. New products and valuation techniques are reviewed and approved by senior management. Cboe Digital’s valuation process for digital assets are fair value estimates that are also validated by the finance control function independently. Independent price verification is performed by finance control through benchmarking fair value estimates with observable market prices or other independent sources. Reasonably designed controls and governance framework are in place and are intended to help ensure quality third-party pricing sources were used.

● Market Risk – Cboe Clear Europe is also exposed to market risk in the event that a clearing participant defaults and the market prices of the securities in its open positions have moved adversely so the clearinghouse can only close out the participant’s obligations at a loss. To help mitigate market risk, Cboe Clear Europe collects collateral on an end of day and intraday basis from clearing participants to cover for the probable loss during normal market conditions, together with contributions to the clearing fund to cover losses if a default occurred during extreme but plausible market conditions. Adverse movements in exchange rates affecting the value of obligations and collateral are factored into the calculation of the amount of collateral to be collected. To help

85

ensure an orderly market, Cboe Digital maintains digital assets to support its clearing operations which may be subject to significant changes in value and therefore exposed to market risk with the fluctuation in market prices. Cboe Digital monitors this risk on a daily, weekly and monthly basis. The business model is such that Cboe Digital earns digital assets and at times may accumulate positions that are subject to market risk. Customer positions do have market risk based on daily activity and settlement prices.

● Investment Risk – Cboe Clear Europe as of September 30, 2023 held $1,308.9 million of clearing member margin deposits, clearing funds, and interoperability funds which are held or invested primarily to provide security of capital while minimizing credit, market and liquidity risks. Effective August 14, 2023, Cboe Clear Europe enacted changes in its rules, and is able to invest the cash collateral received in the form of interoperability fund deposits from clearing participants in certain investments, typically securities issued by pre-approved sovereign issuers and reverse repurchase agreements with overnight maturities. When investments are made in accordance with the policy, Cboe Clear Europe receives the amount of investment earnings and pays the clearing participants those earnings minus a set basis point cost of collateral. Cboe Clear Europe is able to direct the investment of the cash interoperability fund deposits received from the clearing participants within the program parameters and receive an economic benefit from those investments. See Note 12 (“Clearing Operations”) for more information. In the event that a sovereign government or reverse repurchase agreement counterparty defaults, the value we hold as collateral might not be sufficient to cover our capital requirements in the event of defaults. While Cboe Clear Europe seeks to achieve a reasonable rate of return which may generate interest income for clearing participants, Cboe Clear Europe is primarily concerned with preservation of capital and managing the risks associated with these deposits. As Cboe Clear Europe passes on interest revenues (minus costs) to the clearing members, this could include negative or reduced yield due to market conditions. While Cboe Clear Europe has policies and procedures that strive to help ensure that clearing participant collateral is protected, Cboe Clear Europe cannot absolutely assure that these measures and safeguards will be sufficient to protect margin deposits, clearing funds, and interoperability funds from a default or that we will not be materially and adversely affected in the event of a significant default.

On a regular basis, we review and evaluate changes in the status of our counterparties’ creditworthiness. Credit losses such as those described above could adversely affect our condensed consolidated financial position and results of operations. Any such effects to date have been minimal.

Interest Rate Risk

We have exposure to market risk for changes in interest rates relating to our cash and cash equivalents, financial investments, and indebtedness. As of September 30, 2023 and 2022, our cash and cash equivalents and financial investments were $437.1 million and $380.7 million, respectively, of which $220.2 million and $190.0 million is held outside of the United States in various foreign subsidiaries in 2023 and 2022, respectively. The remaining cash and cash equivalents and financial investments are denominated in U.S. dollars. We do not use our investment portfolio for trading or other speculative purposes. Due to the nature of these investments, we have not been exposed to, nor do we anticipate being exposed to, material risks due to changes in interest rates, assuming no change in the amount or composition of our cash and cash equivalents and financial investments.

As of September 30, 2023, we had $1,513.6 million in outstanding debt, of which $1,438.7 million relates to our Senior Notes, which bear interest at fixed interest rates. Changes in interest rates will have no impact on the interest we pay on fixed-rate obligations. $74.9 million of the outstanding debt relates to the Term Loan Agreement, which bears interest at fluctuating rates and, therefore, subjects us to interest rate risk. The overnight Treasury repurchase market underlying SOFR has experienced and may experience disruptions from time to time, which may result in unexpected fluctuations, including potentially higher rates, in SOFR. A hypothetical 100 basis point increase in interest rates relating to the amounts outstanding under the Term Loan Agreement as of September 30, 2023 would decrease annual pre-tax earnings by $0.7 million, assuming no change in the composition of our outstanding indebtedness. We are also exposed to changes in interest rates as a result of borrowings under our Revolving Credit Agreement and the Cboe Clear Europe Credit Facility, as these facilities bear interest at fluctuating rates. As of September 30, 2023, there were no outstanding borrowings under our Revolving Credit Agreement or Cboe Clear Europe Credit Facility, respectively. See Note 10 (“Debt”) to the condensed consolidated financial statements for a discussion of debt agreements.

Liquidity Risk

We are exposed to liquidity risk under certain circumstances in relation to the cross-acceleration and cross-default provisions within the Term Loan Agreement and the Revolving Credit Agreement as a result of the Company, as

86

guarantor, entering into the Cboe Clear Europe Credit Facility. A default of the Facility may allow lenders to accelerate any related drawn amounts and may result in the acceleration of the Company’s other outstanding debt to which a cross-acceleration or cross-default provision applies, which may limit the Company’s liquidity, business and financing activities. See Note 10 (“Debt”) to the condensed consolidated financial statements for a discussion of debt agreements.

Item 4. Controls and Procedures

a)Disclosure controls and procedures. The Company’s management, with the participation of its Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Securities Exchange Act of 1934) as of the end of the period covered by this report. Based upon that evaluation, the Company’s Chief Executive Officer and Chief Financial Officer have concluded that, as of the end of such period, the Company’s disclosure controls and procedures are effective.

b)Internal controls over financial reporting. No changes occurred in the Company’s internal control over financial reporting during the third quarter 2023 that materially affected, or are reasonably likely to materially affect, the Company’s internal control over financial reporting.

PART II—OTHER INFORMATION

Item 1. Legal Proceedings.

Cboe incorporates herein by reference the discussion set forth in Note 19 (“Income Taxes”) and Note 21 (“Commitments, Contingencies, and Guarantees”) of the condensed consolidated financial statements included herein.

Item 1A. Risk Factors.

Except as set forth below, there have been no material updates during the period covered by this Form 10-Q to the Risk Factors as set forth in Item 1A. of our Annual Report on Form 10-K for the year ended December 31, 2022. These risks and uncertainties, however, are not the only risks and uncertainties that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also significantly impact us. Any of these risks and uncertainties may materially and adversely affect our business, financial condition or results of operations, liquidity and cash flows.

If we fail to attract or retain highly skilled management and other employees our business may be harmed.

Our success largely depends on the skills, experience and continued efforts of management and other key personnel. As a result, to be successful, we must retain and motivate executives and other key employees. However, we have no assurances that these employees will remain with us. The roles and responsibilities of departing executive officers and employees will need to be filled either by existing or new officers and employees, which may require us to devote time and resources to identifying, hiring and integrating replacements for the departed executives and employees that could otherwise be used to pursue business opportunities, which could have a material adverse effect on our overall business, financial condition and operating results.

There is substantial competition for qualified and capable personnel, particularly in the technology space, which may make it difficult for us to retain and recruit qualified employees in sufficient numbers. This competition has continued due to tighter supply of available labor, compensation inflation, as well as the growth of new asset classes such as the digital asset space. We have previously faced and may in the future face increased challenges in retaining and attracting qualified employees. If we fail to retain our current employees, it would be difficult and costly to identify, recruit and train replacements needed to continue to conduct and expand our business. In particular, failure to retain and attract qualified technology personnel could result in systems failures. Consequently, our reputation may be harmed, we may incur additional costs and our profitability could decline. There can be no assurance that we will be able to retain and motivate our employees in the same manner as we have historically done.

Additionally, effective succession planning is also important to our long-term success. For example, on September 18, 2023, Edward T. Tilly, former Chief Executive Officer of the Company, resigned and voluntarily terminated his employment with the Company. Following Mr. Tilly’s resignation, Fredric J. Tomczyk, an existing director of the Company, was appointed as Chief Executive Officer of the Company, effective as of the Effective Date. Further, on July 6, 2023, Brian Schell, former Executive Vice President, Chief Financial Officer and Treasurer, announced his departure from the Company to pursue a new professional opportunity outside of the exchange industry. Jill Griebenow, Senior Vice

87

President and Chief Accounting Officer, was appointed to serve as Executive Vice President, Chief Financial Officer, Treasurer and Chief Accounting Officer effective July 10, 2023, and currently serves as Executive Vice President, Chief Financial Officer and Chief Accounting Officer. Failure to ensure effective transfer of knowledge and smooth transitions involving our management team and key employees, including the recent leadership transitions, could hinder our strategic planning and execution.

Our clearinghouse operations expose us to associated risks, including credit, liquidity, market and other risks related to the defaults of clearing participants and other counterparties, and risks related to investing of collateral.

We are subject to risks related to operating our clearinghouse, Cboe Clear Europe, including the risks of failing to meet strict business continuity requirements and regulatory oversight, risks of default by clearing participants and counterparties, due to bankruptcy, lack of liquidity, operational failure or other reasons, the risks associated with the adequacy of participants’ margin, default and interoperable funds, and risks related to investing of such funds. These risks could subject our business to substantial losses, reputational harm, regulatory consequences, including litigation, fines and enforcement actions, and the inability to operate our business, including the continued development of the European derivatives buildout. See below for additional risks related to our digital asset clearinghouse, Cboe Clear Digital.

To mitigate the credit risks related to defaults of clearing participants and other counterparties, including the market risk that we would only be able to close out a defaulting participant’s positions at a loss, there are minimum participation criteria to become a clearing participant and clearing participants are required to provide collateral to cover the margin requirement and default fund contributions. Furthermore, Cboe Clear Europe interoperates with two central counterparties and requires its participants to make deposits to an interoperable fund, which are pledged to the interoperable central counterparties. No guarantee can be given that the collateral provided will at all times be sufficient, maintain its value, or provide absolute assurance against us experiencing financial losses from defaults by the participants or counterparties on their obligations. In addition, although such collateral is preferably held in European central banks, Cboe Clear Europe also holds collateral in central securities depositories and commercial banks, which can expose us to risk of default by those institutions, and invests cash collateral in accordance with its investment policy, such as in securities issued by pre-approved sovereign issuers and reverse repurchase agreements with overnight maturities, which expose us to risk of counterparty default which may result in losses and cause its clearing participants to lose confidence in our clearinghouse.

Cboe Clear Europe entered into a €1.25 billion committed syndicated multicurrency revolving and swingline credit facility that is available to be drawn by Cboe Clear Europe towards (a) financing unsettled amounts in connection with the settlement of transactions in securities and other items processed through Cboe Clear Europe’s clearing system and (b) financing any other liability or liquidity requirement of Cboe Clear Europe incurred in the operation of its clearing system, however we can give no assurance that this facility will be sufficient to meet all such obligations or sufficiently mitigate Cboe Clear Europe’s liquidity risk to meet its payment obligations when due. Substantial amounts of the collateral, and any amounts drawn under this facility, may be at risk if a clearing participant defaults on its obligations to our clearinghouse and its margin, default and interoperability fund deposits are insufficient to meet its obligations. This facility is expected to terminate on June 28, 2024 and we may not be able to enter into a replacement facility on commercially reasonable terms, or at all. Additionally, investment losses in excess of capital set aside by Cboe Clear Europe for counterparty risk are allocated back to clearing participants. We cannot assure you that the mitigating measures, policies, safeguards and risk management procedures will be sufficient to detect problems or to protect us from a default or that we will not be materially and adversely affected in the event of a significant default.

Item 2.       Unregistered Sales of Equity Securities and Use of Proceeds.

Share repurchase program

In 2011, the Board of Directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and subsequently approved additional authorizations for a total authorization of $1.6 billion. The program permits the Company to purchase shares, through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation.

The Company did not repurchase shares under the Company’s share repurchase program during the three months ended September 30, 2023.

Securities Trading Plans of Executive Officers and Directors

During the period from July 1, 2023, to September 30, 2023, our executive officers and directors adopted or terminated contracts, instructions or written plans for the purchase or sale of our securities as noted below.

On September 6, 2023, Edward T. Tilly, our former Chief Executive Officer, terminated a trading arrangement he had previously adopted with respect to the sale of shares of the Company’s common stock (the “Trading Plan”) in connection with an investigation led by the Company’s Board of Directors and outside independent counsel that was launched in late August 2023. Mr. Tilly’s Trading Plan was adopted on March 13, 2023, had a term of one year and provided for the sale of up to 32,000 shares of common stock pursuant to the terms of the plan. As of the date of termination of the Trading Plan, Mr. Tilly had sold 16,000 of common stock under the terms of the Trading Plan.

Exhibit 10.4

CBOE GLOBAL MARKETS, INC. LONG-TERM INCENTIVE PLAN

Restricted Stock Unit Award Agreement

This Restricted Stock Unit Award Agreement (this “Agreement”) is dated effective October 12, 2023 (the “Award Date”), and is between Cboe Global Markets, Inc. (the “Corporation”) and Fredric John Tomczyk (“Participant”).  Any term capitalized but not defined in this Agreement will have the meaning set forth in the Second Amended and Restated Cboe Global Markets, Inc. (formerly CBOE Holdings, Inc.) Long-Term Incentive Plan (as may be amended from time to time, the “Plan”).  

1. Award.  The Corporation hereby awards to Participant 44,452 Restricted Stock Units (the “Restricted Stock Units”).  The Restricted Stock Units will be subject to the terms and conditions of the Plan and this Agreement.  Each Restricted Stock Unit is a notional amount that represents one unvested share of Stock and entitles Participant, subject to the terms of this Agreement, to receive a share of Stock if and when the Restricted Stock Unit vests.  

2. No Rights as Stockholder; Dividend Equivalents.  Participant shall have no voting rights with respect to shares of Stock represented by Restricted Stock Units until the date of the issuance of the shares of Stock (as evidenced by the appropriate entry on the books of the Corporation or of a duly authorized transfer agent of the Corporation).  Notwithstanding the foregoing, in the event that the Corporation declares a cash dividend on shares of Stock, on the payment date of the dividend, Participant will be credited with Dividend Equivalent Rights equal to the amount of the cash dividend per share multiplied by the number of Restricted Stock Units held by Participant on the dividend’s record date.  The Dividend Equivalent Rights credited to Participant under the preceding sentence will be distributed to Participant at the same time as the underlying cash dividend is distributed to shareholders of the Corporation.

3. Vesting; Effect of Termination of Service; Change in Control.

(a)Subject to Sections 3(b) through 3(g) below, Participant’s Restricted Stock Units will vest (i) thirty-three percent (33%) on the twelve (12) month anniversary of the Award Date (the “First Vesting Date”), provided that Participant has remained in Service as the Chief Executive Officer of the Corporation from the date hereof continuously through such date, (ii) thirty-three percent (33%) on the twenty-four (24) month anniversary of the Award Date (the “Second Vesting Date”), provided that Participant has remained in Service from the date hereof as either the Chief Executive Officer of the Corporation or a Director continuously through such date, and (iii) thirty-four percent (34%) on the thirty-six (36) month anniversary of the Award Date (the “Third Vesting Date”), provided that Participant has remained in Service from the date hereof as either the Chief Executive Officer of the Corporation or a Director continuously through such date.

(b)The Restricted Stock Units will vest in full upon the earliest to occur of (i) Participant’s death, (ii) Participant’s becoming Disabled, provided that such condition qualifies as “disability” for purposes of Section 409A, or (iii) the date after the First Vesting date on which (A) Participant ceases to be a Director due to failure to be renominated or re-elected to the Board for any reason other than Cause or a voluntary resignation from the

Board and Participant is not serving as Chief Executive Officer of the Corporation on such Date, or (B) Participant’s Service as Chief Executive Officer of the Corporation terminates for any reason other than Cause and Participant is not providing Service as a non-employee Director on such date due to a failure to be renominated or re-elected to the Board for any reason other than Cause or a voluntary resignation from the Board, in each case, if prior to any forfeiture event under Section 3(f) below; provided, in each case, Participant has remained in Service from the date hereof through such event. For the avoidance of doubt, (x) while Participant is serving as Chief Executive Officer of the Corporation, “Cause” shall have the meaning set forth in the Cboe Global markets, Inc. Executive Severance Plan, as may be amended and/or amended and restated from time to time and (y) while Participant’s Service is solely as a non-employee Director, “Cause” shall have the meaning set forth in the Plan.

(c)If after the First Vesting Date Participant ceases to serve as the Chief Executive Officer of the Corporation, but thereafter remains in the Service of the Corporation as a Director, then notwithstanding anything to the contrary in Section 3(a), if Participant ceases be a Director due to his voluntary resignation from the Board where no basis for Cause exists, then the Restricted Stock Units will vest on a pro-rata basis as of the date of his termination of Service as follows:

i. If Participant’s termination of Service occurs after the First Vesting Date but prior to the Second Vesting Date, by multiplying the number of unvested Restricted Stock Units covered by the Award as of the effective date of termination of Service by a fraction (A) the numerator of which is the number of days of Participant’s Service from the First Vesting Date through the effective date of Termination of Service and (y) the denominator of which is 730, rounded down to the nearest whole share.

ii. If Participant’s termination of Service occurs after the Second Vesting Date but prior to the Third Vesting Date, by multiplying the number of unvested Restricted Stock Units covered by the Award as of the effective date of termination of Service by a fraction (A) the numerator of which is the number of days of Participant’s Service from the Second Vesting Date through the effective date of termination of Service and (y) the denominator of which is 365, rounded down to the nearest whole share.

(d)This subsection 3(d) shall apply to this Agreement, this Award and any Replacement Award provided to Participant to replace this Award in lieu of Section 8.2(b) of the Plan while Participant is employed as the Chief Executive Officer of the Corporation.  Upon a termination of Participant’s Service as the Chief Executive Officer of the Corporation by the Corporation or its Affiliate without Cause or by Participant for “Good Reason” (as defined below), in each case, upon or within two years after a Change in Control and prior to any forfeiture event under Section 3(f) below, this Award or any Replacement Award held by Participant shall become fully vested and free of restrictions and shall be distributed upon or within 60 days of such termination of Service. Notwithstanding the foregoing, if this Award or the Replacement Award, as applicable, is considered deferred compensation subject to Section 409A, payment shall be made pursuant to the Award’s original schedule if necessary to comply with Section 409A.

2

For purposes of this Award “Good Reason” shall be deemed to exist if, and only if, without Participant’s express written consent while he is the Chief Executive Officer of the Corporation:

(i)   The Corporation or its Affiliate assigns to Participant authorities, duties or responsibilities (including titles) that are inconsistent in any material and adverse respect with Participant’s immediately preceding authorities, duties or responsibilities with the Corporation or its Affiliate (including any material and adverse diminution of such immediately preceding authorities, duties or responsibilities);

(ii)  The Corporation or its Affiliate materially reduces Participant’s base compensation;

(iii)   The Corporation or its Affiliate requires Participant to relocate his or her principal business office or principal place of residence outside the metropolitan area in which Participant worked or resided at the time the Restricted Stock Units were awarded (or outside the immediately preceding location of Participant’s principal business office with the Corporation or its Affiliate), or assigns to Participant duties that would reasonably require such relocation;    

(iv)   The Corporation or its Affiliate materially breaches the terms of any agreement pursuant to which services are provided to the Corporation or its Affiliate by Participant; or

(v)    The Corporation or its Affiliate terminates, reduces or limits Participant’s participation in any bonus or incentive compensation arrangement relative to the level of participation of other employees of similar rank for a reason that is not reasonably related to Participant’s level of job performance or local requirements and provided that such action results in a material reduction in the aggregate value of Participant’s incentive compensation below the aggregate value as of the immediately preceding bonus or incentive compensation performance period and provided further that a mere change in the form of payment of the award (whether cash or shares of Stock) without a reduction in the aggregate grant value of the award shall not be considered a reduction of Participant’s participation.

Participant’s voluntary termination of Service shall not be considered a termination of Service for Good Reason unless Participant terminates his or her Service  within 120 days after the initial existence of the condition constituting Good Reason; provided, Participant provides written notice to the Corporation or its Affiliate of Participant’s intention to resign for Good Reason, which notice specifies in reasonable detail the breach or action giving rise thereto within 90 days of its initial existence, and the Corporation or its Affiliate does not cure such breach or action within 30 days after the date of Participant’s notice.

(e)This subsection 3(e) shall apply to this Agreement and this Award while Participant is providing Services to the Corporation solely as a non-employee Director after the First Vesting Date and no longer as the Chief Executive Officer of the Corporation.

3

The Restricted Stock Units, if not sooner vested pursuant to this Section 3, will vest in full upon a Change in Control.

(f)If Participant’s Service is terminated for any reason before all of Participant’s Restricted Stock Units have vested under this Agreement (including pursuant to an event described in Sections 3(b) through 3(e) above), Participant’s unvested Restricted Stock Units will be forfeited upon the effective date of such termination of Service.  Neither the Corporation nor any Affiliate will have any further obligations to Participant under this Agreement if Participant’s Restricted Stock Units are forfeited pursuant to this Section 3(f).

(g)Notwithstanding anything to the contrary, any outstanding Restricted Stock Units not previously settled shall be cancelled and forfeited immediately if, in the sole opinion and discretion of the Board, the Participant engages in any activity that constitutes Cause, whether or not the Participant experiences a separation from Service, is no longer in Service, or remains in Service. Neither the Corporation nor any Affiliate will have any further obligations to Participant under this Agreement if Participant’s Restricted Stock Units are forfeited pursuant to this Section 3(g).

4. Terms and Conditions of Distribution.

(a)Distribution of a share of Stock that corresponds to a vested Restricted Stock Unit shall be made to Participant as soon as practicable after the Restricted Stock Unit vests, but not later than two and a half (2½) months after the end of the calendar year in which such vesting occurs.  

(b)Reserved.

(c)If Participant dies before the date on which the Corporation would have distributed shares of Stock in satisfaction of vested Restricted Stock Units, the Corporation will distribute such shares of Stock to Participant’s designated beneficiary(ies) or, if none are designated or surviving, to Participant’s estate or personal representative.  The Corporation is not required to issue or deliver any shares of Stock before completing the steps necessary to comply with applicable Federal and state securities laws (including any registration requirements) and applicable stock exchange rules and practices.  The Corporation will use commercially reasonable efforts to cause compliance with those laws, rules and practices.  The foregoing provisions are subject in all cases to the requirements of Section 409A.  

5. Nontransferability.  Unvested Restricted Stock Units may not be sold, transferred, exchanged, pledged, assigned, garnished, or otherwise alienated or hypothecated, other than by will or by the laws of descent and distribution.  Any effort to assign or transfer the rights under this Agreement will be wholly ineffective, and will be grounds for termination by the Committee of all rights of Participant under this Agreement.

6. Administration.  The Committee administers the Plan.  Participant’s rights under this Agreement are expressly subject to the terms and conditions of the Plan and to any guidelines the Committee adopts from time to time.  The interpretation and construction by the Committee of the Plan and this Agreement, and such rules and regulations as may

4

be adopted by the Committee for purposes of administering the Plan and this Agreement, will be final and binding upon Participant.  

7. Securities Law Requirements.  If at any time the Board or Committee determines that issuing Stock pursuant to this Agreement would violate applicable securities laws, the Corporation will not be required to issue such Stock.  The Board or Committee may declare any provision of this Agreement or action of its own null and void, if it determines the provision or action fails to comply with applicable securities laws.  The Corporation may require Participant to make written representations it deems necessary or desirable to comply with applicable securities laws.

8. Payment of Withholding Taxes.  The Participant acknowledges that, regardless of any action taken by the Corporation or, if different, the Affiliate of the Corporation that employs the Participant (the “Employer”), the ultimate liability for all income tax, social contributions, payroll tax, fringe benefits tax, payment on account or other tax-related items related to the Participant’s participation in the Plan and legally applicable to the Participant or deemed by the Corporation or the Employer in their discretion to be an appropriate charge to the Participant even if legally applicable to the Corporation or the Employer (“Tax-Related Items”), is and remains the Participant’s responsibility and may exceed the amount actually withheld by the Corporation or the Employer, if any. The Participant further acknowledges that the Corporation and/or the Employer (a) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the Restricted Stock Units, including, but not limited to, the grant, vesting or settlement of the Restricted Stock Units, the subsequent sale of shares of Stock acquired pursuant to such settlement; and (b) do not commit to and are under no obligation to structure the terms of the grant or any aspect of the Restricted Stock Units to reduce or eliminate the Participant’s liability for Tax-Related Items or achieve any particular tax result. Further, if the Participant is subject to Tax-Related Items in more than one jurisdiction between the Award Date and the date of any relevant taxable or tax withholding event, as applicable, the Participant acknowledges that the Corporation and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

Prior to the relevant taxable or tax withholding event, as applicable, the Participant agrees to make adequate arrangements satisfactory to the Corporation and/or the Employer to satisfy all Tax-Related Items. In this regard, the Participant authorizes the Corporation, or its respective agents, at their discretion, to satisfy the obligations with regard to all Tax-Related Items by one or a combination of the following: (i) withholding from the Participant’s wages or other cash compensation paid to the Participant by the Corporation and/or the Employer; (ii) withholding from the shares of Stock to be delivered upon settlement of the Restricted Stock Units or other awards granted to the Participant or (iii) permitting the Participant to tender to the Corporation or to the Employer cash or, if allowed by the Committee, shares of Stock to the Corporation.

Notwithstanding the foregoing, if the Participant is subject to Section 16 of the United States Securities Exchange Act of 1934, as amended, pursuant to Rule 16a-2 promulgated thereunder, any tax withholding obligations shall be satisfied by having the Corporation

5

withhold from the shares of Stock to be delivered upon settlement of the Restricted Stock Units.

Depending on the withholding method, the Corporation may withhold or account for Tax-Related Items by considering applicable statutory withholding rates (as determined by the Corporation in good faith and in its sole discretion) or other applicable withholding rates, including maximum applicable rates, in which case the Participant will receive a refund of any over-withheld amount in cash and will have no entitlement to the share equivalent. If the obligation for Tax-Related Items is satisfied by withholding from the shares of Stock to be delivered upon settlement of the Restricted Stock Units, for tax purposes, the Participant is deemed to have been issued the full number of shares of Stock subject to the Restricted Stock Units, notwithstanding that a number of shares of Stock are held back solely for the purpose of paying the Tax-Related Items. The Participant will have no further rights with respect to any shares of Stock that are retained by the Corporation pursuant to this provision.

The Participant agrees to pay to the Corporation or the Employer any amount of Tax-Related Items that the Corporation or the Employer may be required to withhold or account for as a result of the Participant’s participation in the Plan that cannot be satisfied by the means previously described. The Corporation may refuse to issue or deliver shares of Stock or proceeds from the sale of shares of Stock until arrangements satisfactory to the Corporation have been made in connection with the Tax-Related Items.

9. Restrictive Covenants.  Participant understands the global nature of the Corporation’s businesses and the effort the Corporation and its Affiliates (collectively referred to in this Section as “Cboe”) undertake to develop and protect their business and their competitive advantage.  Accordingly, Participant agrees that the scope and duration of the restrictions described in this Agreement are reasonable and necessary to protect the legitimate business interests of Cboe.  Participant further agrees that during the period of Participant’s Service and for a period of two (2) years following Participant’s separation from Service, Participant shall not, without the express written approval of the Chief Executive Officer:

(a)singly, jointly, or in any other capacity, in a manner that contributes to any research, technology, development, account, trading, marketing, promotion, or sales and that relates to Participant’s Service with Cboe, directly or beneficially, manage, join, participate in the management, operation or control of, or work for (as an employee, consultant or independent contractor), or permit the use of his or her name by, or provide financial or other assistance to, or be connected in any manner with (i) any exchange, facility, clearinghouse, electronic communications network (“ECN”), electronic foreign currency exchange market (“FX”) matching platform, multilateral trading facility, or alternative trading system (“ATS”); (ii) the ECN, ATS or FX business lines of any full service broker dealer or any digital asset or data and access solution business line of any company; or (iii) any business line of any company that is substantially similar to any additional business line developed or entered into by Cboe during Participant’s Service, provided that, in the case of clauses (i), (ii) and (iii), such entity or business line that directly competes with Cboe;

6

(b)provide any service or assistance that (i) is of the general type of service or assistance provided by Participant to Cboe, (ii) relates to any technology, account, product, project or piece of work with which Participant was involved during his Service, and (iii) contributes to causing an entity to come within the definition described in Section 9(a) above;

(c)solicit or accept if offered to Participant, with or without solicitation, on his or her own behalf or on behalf of any other person, the services of any person who is a then-current employee of Cboe (or was an employee of Cboe during the year preceding such solicitation), nor solicit any of Cboe’s then-current employees (or an individual who was employed by or engaged by Cboe during the year preceding such solicitation) to terminate employment or an engagement with Cboe, nor agree to hire any then-current employee (or an individual who was an employee of Cboe during the year preceding such hire) of Cboe into employment with Participant or any company, individual or other entity; or

(d)directly or indirectly divert or attempt to divert from Cboe any business in which Cboe has been actively engaged during Participant’s Service, nor interfere with the relationships of Cboe or with their sources of business.

10. Confidentiality.  Participant acknowledges that the Corporation or an Affiliate may disclose secret or confidential information to Participant during the period of Participant’s Service to enable Participant to perform his or her duties.  Participant agrees that, subject to the following sentence, Participant shall not during his or her Service (except in connection with the proper performance of his or her duties) and thereafter, without the prior written consent of the Corporation, disclose to any person or entity any material or significant secret or confidential information concerning the business of the Corporation or an Affiliate that was obtained by Participant in the course of Participant’s Service.  This paragraph shall not be applicable if and to the extent Participant is required to testify in a legislative, judicial or regulatory proceeding pursuant to an order of Congress, any state or local legislature, a judge, or an administrative law judge, or if such secret or confidential information is required to be disclosed by Participant by any law, regulation or order of any court or regulatory commission, department or agency.  Participant further agrees that if Participant’s Service is terminated for any reason, Participant will not take, but will leave with the Corporation or an Affiliate, all records and papers and all matter of whatever nature that bears secret or confidential information of the Corporation or an Affiliate.  For purposes of this Agreement, the term “secret or confidential information” shall include, but not be limited to, any and all records, notes, memoranda, data, writings, research, personnel information, customer information, clearing members’ information, the Corporation’s and any Affiliate’s financial information and plans, processes, methods, techniques, systems, formulas, patents, models, devices, compilations or any other information of whatever nature in the possession or control of the Corporation or an Affiliate, that has not been published or disclosed to the general public, the options industry, the equities industry, the foreign currency exchange industry or the commodities futures industry, provided that such term shall not include knowledge, skills, and information that is common to the trade or profession of Participant.

7

Notwithstanding anything in this Agreement to the contrary, nothing in this Agreement prohibits Participant from confidentially or otherwise communicating or filing a charge or complaint with a governmental or regulatory entity, participating in a governmental or regulatory entity investigation, or giving truthful testimony or making other disclosures to a governmental or regulatory entity (in each case, without having to disclose any such conduct to theCorporation or an Affiliate), or from responding if properly subpoenaed or otherwise required to do so under applicable law.  In addition, nothing in this Agreement limits Participant’s right to receive an award from a governmental or regulatory entity for information provided to such an entity (and not as compensation for actual or alleged personal injury or damages to Participant).

Pursuant to the Defend Trade Secrets Act of 2016 (18 U.S.C. 1833(b)), Participant shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made in confidence either directly or indirectly to a federal, state, or local government official, or to an attorney, solely for the purpose of reporting or investigating a violation of law.  Participant shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret made in a complaint, or other document filed in a lawsuit or other proceeding, if such filing is made under seal.  If Participant files a lawsuit or other action alleging retaliation by the Corporation or an Affiliate for reporting a suspected violation of law, Participant may disclose the trade secret to his or her attorney and use the trade secret in the court proceeding or other action, if Participant files any document containing the trade secret under seal and does not disclose the trade secret, except pursuant to court order.  This paragraph will govern to the extent it may conflict with any other provision of this Agreement.

11. Judicial Modification.  If the final judgment of a court of competent jurisdiction declares that any term or provision of Section 9 or 10 is invalid or unenforceable, the parties agree that (a) the court making the determination of invalidity or unenforceability shall have the power to reduce the scope, duration, or geographic area of the term or provision, to delete specific words or phrases, or to replace any invalid or unenforceable term or provision with a term or provision that is valid and enforceable and that comes closest to expressing the intention of the invalid or unenforceable term or provision, (b) the parties shall request that the court exercise that power, and (c) this Agreement shall be enforceable as so modified after the expiration of the time within which the judgment or decision may be appealed.

12. Remedies.  Participant agrees that in the event of a breach or threatened breach of any of the covenants contained in Sections 9 or 10 of this Agreement, in addition to any other penalties or restrictions that may apply under any employment agreement, state law, or otherwise, Participant shall forfeit, upon written notice to such effect from the Corporation, any and all Awards granted to him or her under the Plan and this Agreement, including vested Awards.  The forfeiture provisions of this Section 12 shall continue to apply, in accordance with their terms, after the provisions of any employment or other agreement between the Corporation and Participant have lapsed.  Participant consents and agrees that if Participant violates or threatens to violate any provisions of Sections 9 or 10 of this Agreement, the Corporation or its successors in interest shall be entitled, in addition to any other remedies that they may have, including money damages, to an injunction to be issued

8

by a court of competent jurisdiction restraining Participant from committing or continuing any violation of Sections 9 or 10.  In the event that Participant is found to have breached any provision set forth in Section 9 of this Agreement, the time period provided for in that provision shall be deemed tolled (i.e., it will not begin to run) for as long as Participant was in violation of that provision. The provisions of Sections 9 and 10 of this Agreement shall continue to apply, in accordance with their terms, after Participant's service has terminated and after provisions of any employment or other agreement between the Corporation and Participant have lapsed.

13. Representations and Warranties.  Participant represents and warrants to the Corporation that Participant has received a copy of the Plan and this Agreement, has read and understands the terms of the Plan and this Agreement, and agrees to be bound by their terms and conditions in all respects.

14. No Limitation on the Corporation’s Rights.  The granting of Restricted Stock Units under this Agreement shall not and will not in any way affect the Corporation’s right or power to make adjustments, reclassifications or changes in its capital or business structure or to merge, consolidate, reincorporate, dissolve, liquidate or sell or transfer all or any part of its business or assets.

15. Plan and Agreement Not a Contract of Employment or Service.  Neither the Plan nor this Agreement is a contract of employment or Service, and no terms of Participant’s employment or Service will be affected in any way by the Plan, this Agreement or related instruments, except to the extent specifically expressed therein.  Neither the Plan nor this Agreement will be construed as conferring any legal rights on Participant to continue to be employed or remain in Service, nor will it interfere with the Corporation’s or any Affiliate’s right to discharge Participant or to deal with Participant regardless of the existence of the Plan or this Agreement.

16. Entire Agreement and Amendment.  This Agreement and the Plan constitute the entire agreement between the parties hereto with respect to the Restricted Stock Units, and all prior oral and written representations are merged in this Agreement and the Plan.  Notwithstanding the preceding sentence, this Agreement shall not in any way affect the terms and provisions of the Plan.  This Agreement may be amended, modified, or terminated only in accordance with the Plan.  The headings in this Agreement are inserted for convenience and identification only and are not intended to describe, interpret, define or limit the scope, extent, or intent of this Agreement or any provision hereof.

17. Notice. Any notice or other communication required or permitted under this Agreement must be in writing and must be delivered personally, sent by certified, registered or express mail, sent by overnight courier (at the sender’s expense), or (if from the Corporation or the Corporation’s stock plan administrator) by electronic mail.  Notice will be deemed given (a) when delivered personally, (b) if mailed, three days after the date of deposit in the U.S. mail, (c) if sent by overnight courier, on the regular business day following the date sent, or (d) when electronically mailed.  Notice to the Corporation should be sent to Cboe Global Markets, Inc., 433 West Van Buren Street, Chicago, Illinois 60607, Attention: General Counsel.  Notice to Participant should be sent to the mailing address and/or electronic mailing address set forth on the Corporation’s records.  Either party may change the address

9

to which the other party must give notice under this Section 17 by giving the other party written notice of such change, in accordance with the procedures described above or otherwise established by the Corporation or its stock plan administrator.

18. Successors and Assigns.  The terms of this Agreement will be binding upon the Corporation and its successors and assigns.

19. Governing Law.  To the extent not preempted by Federal law, the Plan, this Agreement, and documents evidencing rights relating to the Plan or this Agreement will be construed, administered and governed in all respects under and by the laws of the State of Delaware, without giving effect to its conflict of laws principles.  If any provision of this Agreement will be held by a court of competent jurisdiction to be invalid or unenforceable, the remaining provisions hereof will continue to be fully effective.  The jurisdiction and venue for any disputes arising under, or any action brought to enforce (or otherwise relating to), this Agreement will be exclusively in the courts in the State of Illinois, County of Cook, including the Federal Courts located therein (should Federal jurisdiction exist).

20. Plan Document Controls.  The rights granted under this Agreement are in all respects subject to the provisions set forth in the Plan to the same extent and with the same effect as if set forth fully in this Agreement.  If the terms of this Agreement conflict with the terms of the Plan document, the Plan document will control.

21. Counterparts.  This Agreement may be executed simultaneously in two or more counterparts, each of which shall be deemed an original and all of which together shall constitute but one and the same instrument.

22. Waiver; Cumulative Rights.  The failure or delay of either party to require performance by the other party of any provision of this Agreement will not affect its right to require performance of such provision unless and until such performance has been waived in writing.  Each right under this Agreement is cumulative and may be exercised in part or in whole from time to time.

23. Tax Consequences.Participant agrees to determine and be responsible for all tax consequences to Participant with respect to the Restricted Stock Units.

24. Section 409A. The Restricted Stock Units granted hereunder are intended to comply with, or otherwise be exempt from, Section 409A, including the exceptions and exemptions for short term deferrals, stock rights, and separation pay arrangements. This Agreement and all Restricted Stock Units shall be administered, interpreted, and construed in a manner consistent with Section 409A. Should any provision of this Agreement, or any other agreement or arrangement contemplated by this Agreement, be found not to comply with, or otherwise be exempt from, the provisions of Section 409A, such provision shall be modified and given effect (retroactively if necessary), in the sole discretion of the Corporation, and without the consent of Participant, in such manner as the Corporation determines to be necessary or appropriate to comply with, or to effectuate an exemption from, Section 409A. Notwithstanding the forgoing, no provision of this Agreement, or any other agreement or arrangement contemplated by this Agreement shall be construed as a guarantee by the Corporation of any particular tax effect to Participant.  Each payment

10

made under this Agreement shall be designated as a separate payment within the meaning of Section 409A.  Any payment that is subject to Section 409A and payable upon Participant’s termination of employment or other similar event shall not be made unless Participant has experienced a “separation from service” as defined under Section 409A.  Any payment subject to Section 409A that is to be made upon a “separation from service” to Participant on any date when he or she is a “specified employee” as defined under Section 409A shall not be paid before the date that is six (6) months following Participant’s “separation from service” or, if earlier, Participant’s death. 

25. Awards Subject to the Corporation’s Recovery of Funds Policy.  Notwithstanding anything in this Agreement to the contrary, the Restricted Stock Units covered by this Agreement shall be subject to the Corporation’s compensation recovery policy, as may be in effect from time to time, including, without limitation, the provisions of any such policy required by Section 10D of the Exchange Act and any applicable rules or regulations issued by the SEC or any national securities exchange or national securities association on which the Stock may be traded.

26. Addendum to Agreement.  Notwithstanding any provision of this Agreement to the contrary, if Participant resides or is employed outside the U.S. or transfers residence or employment outside the U.S., the Restricted Stock Units shall be subject to such special terms and conditions as are set forth in the addendum to this agreement (the “Addendum”).  Further, if Participant transfers residency and/or employment to another country, any special terms and conditions for such country will apply to the Restricted Stock Units to the extent the Corporation determines, in its sole discretion, that the application of such terms and conditions is necessary or advisable in order to comply with local law or to facilitate the operation and administration of the Restricted Stock Units and the Plan (or the Corporation may establish alternative terms and conditions as may be necessary or advisable to accommodate Participant’s transfer).  In all circumstances, the Addendum shall constitute part of this Agreement.

11

IN WITNESS WHEREOF, the Corporation and Participant have duly executed this Agreement as of the date first written above.

ADDENDUM

CBOE GLOBAL MARKETS, INC. LONG-TERM INCENTIVE PLAN
RESTRICTED STOCK UNIT AWARD AGREEMENT

This Addendum to the Agreement includes additional terms and conditions that govern the Restricted Stock Units if Participant resides and/or is employed outside of the United States or transfers residence or employment outside the United States.  Certain capitalized terms used but not defined in this Addendum have the meanings set forth in the Agreement or the Plan.

1. Nature of Grant.  In accepting the Restricted Stock Units, Participant acknowledges that:

(a) the Plan is established voluntarily by the Corporation, is discretionary in nature and may be modified, amended, suspended or terminated by the Corporation at any time, to the extent permitted by the Plan;

(b) the award of the Restricted Stock Units is exceptional, discretionary, voluntary and occasional and does not create any contractual or other right to receive future grants of Restricted Stock Units, or benefits in lieu of Restricted Stock Units, even if Restricted Stock Units have been granted in the past;

(g) this Agreement, the transactions contemplated hereunder and the vesting schedule set forth herein do not constitute an express or implied promise of Participant’s further employment for the vesting period, for any period, or at all, and will not interfere with Participant’s right or the right of the Corporation or the Employer to terminate Participant’s employment relationship at any time with or without cause;

2. Payment of Withholding Taxes.  Participant acknowledges and agrees that if Participant is subject to tax and/or social contributions in more than one jurisdiction, the Corporation or its Affiliate(s) may be required to withhold or account for taxes and/or social contributions in more than one jurisdiction, in accordance with the methods of withholding described in Section 8 of the Agreement.

3. Data Privacy.

(a) Data Collection and Usage. The Corporation and the Employer will collect, process and use certain personal information about Participant, specifically, Participant’s name, home address, email address and telephone number, date of birth, social security or insurance number, passport number or other identification number, salary, nationality, job title, any shares of Stock or directorships held in the Corporation, details of all Restricted Stock Units or any other entitlement to shares of Stock awarded, canceled, exercised, vested, unvested or outstanding in Participant’s favor (“Data”), for the exclusive purpose of implementing, administering and managing the Plan.

(b) Recipients of Data.

14

a. Stock Plan Administration Service Providers. The Corporation and the Employer transfer Data to Fidelity Stock Plan Services, LLC (and/or its affiliates, collectively “Fidelity”), the designated broker assisting in the implementation, administration and management of the Plan. In the future, the Corporation may select a different service provider and share Data with such other provider serving in a similar manner.

b. Other Service Provider Data Recipients. The Corporation also may transfer Data to other third party service providers, if necessary to ensure compliance with applicable tax, exchange control, securities and labor law. Such third party service providers may include the Corporation’s legal counsel as well as its auditor, human resources consultant and payroll vendor. Wherever possible, the Corporation will anonymize data, but Participant understands that his or her Data may need to be transferred to such providers to ensure compliance with applicable law and/or tax requirements.

c. Securities or Other Regulatory Authorities. In addition to the recipients identified herein and where required under applicable law, Data also may be disclosed to certain securities or other regulatory authorities, including where the Corporation’s securities are listed or traded or regulatory filings are made. The legal basis, where required, for such disclosure is compliance with applicable law.

(c) International Data Transfers. The Corporation, Fidelity and other service providers described above are located in the United States. The United States may have different data privacy laws and protections than Participant’s country of residence (or country of employment, if different).

(d) Legal Basis for Collection, Processing and Transfer of Data.

a. Participants within the EU / European Economic Area (“EEA”), Switzerland and the United Kingdom

i. The collection, processing and transfer of Data is necessary for the legitimate purpose of the Corporation and Employer’s administration of the Plan and Participant’s participation in the Plan.

ii. When transferring Data to potential recipients outside the EU/EEA, Switzerland and/or the United Kingdom, the Corporation and the Employer strive to provide appropriate safeguards in accordance with Standard Contractual Clauses or other legally binding and permissible arrangements. For further information on the transfer of Participant’s personal data outside of the EU/EEA, Switzerland and/or the United Kingdom, Participant may contact his or her human resources representative.

b. Participants outside the EU / EEA, Switzerland and the United Kingdom

i. Participant hereby explicitly and unambiguously consents to the collection, processing and use, in electronic or other form, of Participant’s Data by the Corporation and the transfer of Data to the recipients mentioned above, including recipients located in countries

15

which do not adduce an adequate level of protection from a non-U.S. data protection law perspective, for the purposes described above. Upon transfer of Participant’s Data to Fidelity, Participant may be asked to agree to separate terms and data processing practices with Fidelity, with such agreement being a condition of the ability to participate in the Plan.

ii. Participation in the Plan is voluntary and Participant understands that Participant is providing the consent herein on a purely voluntary basis. If Participant does not consent, or later seeks to revoke his or her consent, Participant’s employment status or Service and career with the Employer will not be adversely affected. The only consequence of refusing or withdrawing consent is that the Corporation would not be able to grant Restricted Stock Units or other equity awards to Participant or administer or maintain such awards. Therefore, Participant understands that refusing or withdrawing his or her consent may affect Participant’s ability to participate in the Plan. For more information on the consequences of Participant’s refusal to consent or withdrawal of consent, Participant understands that Participant may contact his or her human resources representative.

(e) Data Retention. Participant understands that Data will be held only as long as is necessary to implement, administer and manage his or her participation in the Plan or comply with applicable laws. When the Corporation no longer needs the Data, the Corporation will remove it from its systems.

(f) Data Subject Rights. Participant understands that Participant may have the right under applicable law to (i) access or copy Data that the Corporation possesses, (ii) rectify incorrect Data, (iii) delete Data, (iv) restrict processing of Data, (v) opt out of the Plan, or (vi) lodge complaints with the competent supervisory authorities in Participant’s jurisdiction. To receive clarification regarding these rights or to exercise these rights, Participant understands that Participant can contact his or her local human resources representative.

4. No Advice Regarding Grant.  The Corporation is not providing any tax, legal or financial advice, nor is the Corporation making any recommendations regarding Participant’s participation in the Plan, or Participant’s acquisition or sale of the underlying shares of Stock.  Participant should consult with his or her own personal tax, legal and financial advisors regarding Participant’s participation in the Plan before taking any action related to the Plan.

5. Imposition of Other Requirements.  The Corporation reserves the right to impose other requirements on Participant’s participation in the Plan, on the Restricted Stock Units and on any shares of Stock acquired under the Plan, to the extent the Corporation determines it is necessary or advisable for legal or administrative reasons.  Such requirements may include (but are not limited to) requiring Participant to sign any agreements or undertakings that may be necessary to accomplish the foregoing.

16

6. Insider Trading/Market Abuse Laws.  By participating in the Plan, Participant agrees to comply with the Corporation’s policy on insider trading (to the extent that it is applicable to Participant). Participant further acknowledges that, depending on Participant’s or the broker’s country of residence or where the shares of Stock are listed, Participant may be subject to insider trading restrictions and/or market abuse laws, which may affect Participant’s ability to accept, acquire, sell or otherwise dispose of shares of Stock, rights to shares of Stock (e.g., Restricted Stock Units) or rights linked to the value of shares of Stock, during such times Participant is considered to have “inside information” regarding the Corporation as defined by the laws or regulations in Participant’s country.  Local insider trading laws and regulations may prohibit the cancellation or amendment of orders Participant places before Participant possessed inside information.  Furthermore, Participant could be prohibited from (i) disclosing the inside information to any third party (other than on a “need to know” basis) and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Participant understands that third parties include fellow employees. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Corporation insider trading policy.  Participant acknowledges that it is Participant’s responsibility to comply with any applicable restrictions, and that Participant should therefore consult Participant’s personal advisor on this matter.

7. Foreign Asset/Account Reporting; Exchange Controls.  Participant’s country may have certain foreign asset and/or account reporting requirements and/or exchange controls which may affect Participant’s ability to acquire or hold shares of Stock under the Plan or cash received from participating in the Plan (including from any dividends received or sale proceeds arising from the sale of shares of Stock) in a brokerage or bank account outside Participant’s country.  Participant may be required to report such accounts, assets or transactions to the tax or other authorities in his or her country.  Participant also may be required to repatriate sale proceeds or other funds received as a result of Participant’s participation in the Plan to his or her country through a designated bank or broker and/or within a certain time after receipt.  Participant acknowledges that it is his or her responsibility to be compliant with such regulations, and Participant should consult his or her personal legal advisor for any details.

8. Language.  If Participant is resident in a country where English is not an official language, Participant acknowledges that Participant is sufficiently proficient in English to understand the terms and conditions of the Agreement or has had the ability to consult with an advisor who is sufficiently proficient in the English language.  Participant further acknowledges and agrees that it is Participant’s express intent that the Agreement, the Addendum and the Plan and all other documents, notices and legal proceedings entered into, given or instituted pursuant to the Restricted Stock Units be drawn up in English.  If Participant has received the Agreement, the Addendum or any other document related to the Plan translated into a language other than English and if the meaning of the translated version is different than the English version, the English version will control.

9. Annex to Addendum.  Notwithstanding any provision of the Agreement or Addendum to the contrary, the Restricted Stock Units shall be subject to such special terms and conditions for Participant’s country of residence (and country of employment, if different), as are set

17

forth in the annex to this Addendum (the “Annex”).  Further, if Participant transfers residency and/or employment to another country, the Corporation may establish alternative terms and conditions as may be necessary or advisable to accommodate Participant’s transfer.  In all circumstances, the Annex shall constitute part of this Addendum.

18

ANNEX

This Annex to the Addendum includes additional terms and conditions that govern the Restricted Stock Units if Participant resides and/or is employed in the country addressed herein or transfers residence or employment to the country addressed herein.  If Participant transfers residence and/or employment to another country, the Corporation may establish alternative terms and conditions as may be necessary or advisable to accommodate Participant’s transfer.  Certain capitalized terms used but not defined in this Annex have the meanings set forth in the Agreement (including the Addendum) or the Plan.

Australia

1. Tax Notification. The Plan is a plan to which Subdivision 83A-C of the Income Tax Assessment Act 1997 (Cth) (the “Act”) applies (subject to conditions in the Act).

2. Offer Document.The Corporation is pleased to provide this offer to participate in the Plan. This offer document sets out information regarding the award for Australian-resident Participants (“Australian Participants”). It is for informational purposes and is intended to comply with the provisions of the Australian Corporations Act 2001 (Cth) (“Corporations Act 2001”) and Australian Securities and Investments Commission (“ASIC”) Instrument 22-0283.

Additional Documents

In addition to the information set out in the Agreement (including the Addendum and this Annex), Participant is also being provided with copies of the following documents:

1. the Plan; and

2. the Plan Prospectus describing the terms of the Plan (the “Plan Prospectus”); and

3. any supplemental documents to the Plan and Plan Prospectus, as necessary.

These additional documents provide further information to help Participant make an informed investment decision about participating in the Plan. Neither the Plan nor the Plan Prospectus is a prospectus for the purposes of the Corporations Act 2001.

Participant should not rely upon any oral statements made in relation to this offer. Participant should rely only upon the statements contained in the Agreement and the additional documents when considering participation in the Plan.

General Information Only

Any information given by the Corporation or any subsidiary or affiliate in relation to the Restricted Stock Units is general and does not take into account an Australian Participant’s objectives, financial situation and needs. Australian Participants should consider obtaining their own financial product advice from an independent person who is licensed by ASIC to give such advice.

19

Acquisition Price

No acquisition price is payable by Participant for the Corporation to grant Participant the number of Restricted Stock Units set forth in the Agreement or for Participant to acquire shares of Stock upon settlement of the Restricted Stock Units.

Shares of Stock

A share of common stock of a U.S. corporation is analogous to an ordinary share of an Australian Corporation. Each holder of a share of common stock is entitled to one vote for every share held.

The shares of Stock are traded on Cboe BZX in the United States of America under the symbol “CBOE”.

Shares of Stock are not liable to any further calls for payment of capital or for other assessment by the Corporation and have no sinking fund provisions, pre-emptive rights, conversion rights or redemption provisions.

Risks of Acquiring Shares of Stock

This paragraph provides Australian Participants with general information about the risks of acquiring and holding shares of Stock. Before accepting the grant of Restricted Stock Units, Australian Participants should satisfy themselves that they have a sufficient understanding of these matters and should consider whether shares of Stock are a suitable investment for them, having regard to their own investment objectives, financial circumstances and taxation position.

(a)Price of shares of Stock may fluctuate: The price at which a share of Stock is quoted on the Cboe BZX may increase or decrease due to a number of factors. Some of the factors that may affect the price of the shares of Stock include fluctuations in the domestic and international market for listed stocks, general economic conditions, including interest rates, inflation rates, changes to government fiscal, monetary or regulatory policies, legislation or regulation, the nature of the markets in which the Corporation operates and general operational and business risks.

More information about potential factors that could affect the Corporation’s business and financial results is included in the Corporation’s Quarterly Reports on Form 10-Q and Annual Reports on Form 10-K. Copies of these forms are available at http://www.sec.gov/ and upon request to the Corporation.

In addition, Participant should be aware that the value of the shares of Stock Participant may acquire will be affected by the U.S./Australian dollar exchange rate. Participation in the Plan involves certain risks related to fluctuations in this rate of exchange.

(b)Trading in shares of Stock may not be liquid: There can be no guarantee that an active market in shares of Stock will continue or that the price of shares of Stock will increase. The number of potential buyers or sellers of shares of Stock on the Cboe BZX

20

may vary at any time. This may increase the volatility of the market price of shares of Stock. It may also affect the prevailing market price at which shareholders are able to sell their shares of Stock. This may result in shareholders receiving a market price for their shares of Stock that is less than the price that shareholders paid.

(c)Risk of dilution: In the future, the Corporation may elect to issue stock (or securities convertible into stock) including in connection with fundraisings for acquisitions that the Corporation may decide to make. Shareholders may be diluted as a result of such issues of stock or securities or such issues may reduce the market price of shares of Stock.

(d)Dividends on shares of Stock: The Corporation may pay dividends on shares of Stock. Payment of future dividends, and the timing and amount of any dividends the Corporation determines to pay, are at the discretion of the Board.

Market Price of shares of Stock in Australian Dollars

An Australian Participant can, from time to time, ascertain the market price of the shares of Stock by obtaining that price from the Corporation website (http://ir.cboe.com/) or The Wall Street Journal. The Australian dollar equivalent of that price can be obtained at the website of the Reserve Bank of Australia (http://www.rba.gov.au/statistics/frequency/exchange-rates.html).

This will not be a prediction of what the market price per share will be when the Restricted Stock Units vest and the shares of Stock are issued or of the applicable exchange rate on the actual vesting date or the date the shares of Stock are issued.

Canada

1. Settlement of Restricted Stock Units: Notwithstanding anything to the contrary in the Agreement or any related document, if Participant is resident or employed in Canada, the Corporation shall have absolute discretion to settle the Restricted Stock Units in shares of Stock or in the form of a cash payment or in any combination of the foregoing.

2. Securities Law Notification: Participant acknowledges and agrees that he or she is permitted to sell shares of Stock acquired under the Plan through the designated broker appointed under the Plan, provided the resale of shares of Stock takes place outside of Canada through facilities of a stock exchange on which the shares of Stock are listed. The shares of Stock currently are listed on Cboe BZX in the United States.

3. Termination of Employment: Except as may be determined by the Committee and except as otherwise provided in Section 3 of the Agreement, for purposes of Sections 3(f) and 3(g) of the Agreement, Participant’s Service will be considered terminated as of the date Participant ceases to be an employee of the Corporation (or, if different, the Affiliate to which Participant provides Service) for any reason, whether lawful or otherwise (including, without limitation, by reason of resignation, death, frustration of contract, termination for Cause, termination without Cause, or constructive dismissal), without regard to any pay in lieu of notice (whether by way of lump sum or salary continuance), benefits continuance, or other termination related

21

payments or benefits, whether pursuant to the common law or otherwise, to which Participant may then be entitled (the “Termination Date”).  In the event that the Termination Date cannot reasonably be determined under the terms of the Plan and the Agreement, the Committee and its delegate shall have the exclusive discretion to determine when the Termination Date occurs for purposes of the Plan (including whether Participant may still be considered to be providing Service while on any leave of absence).

Unless otherwise extended by the Corporation, or as may be required to satisfy the minimum requirements of applicable employment or labour standards legislation, any portion of the award that is not vested on the Termination Date shall terminate immediately and be null and void, and Participant will have no entitlement to further vesting in the Restricted Stock Units or compensation in lieu thereof following the Termination Date, and Participant waives any claim to damages in respect thereof whether related or attributable to any contractual or common law termination entitlements or otherwise. For additional clarity, if applicable employment or labour standards legislation specifically requires continued entitlement to vesting during a statutory notice period, Participant’s right to vest in the Restricted Stock Units, if any, will be allowed to continue for that minimum notice period but then immediately terminate effective as of the last day of Participant’s minimum statutory notice period.

Hong Kong

1. Settlement in Shares of Stock.  Notwithstanding anything to the contrary in the Agreement, the Addendum or the Plan, the Restricted Stock Units shall be settled only in shares of Stock (and may not be settled in cash).

2. Disposal of Shares of Stock.  If, for any reason, shares of Stock are issued to Participant within six (6) months after the Award Date, Participant agrees that Participant will not sell or otherwise dispose of any such shares of Stock prior to the six (6) month anniversary of the Award Date.

3. IMPORTANT NOTICE/WARNING.  The contents of this document have not been reviewed by any regulatory authority in Hong Kong. Participant is advised to exercise caution in relation to the offer.  If Participant is in any doubt about any of the contents of the documents, Participant should obtain independent professional advice. The Restricted Stock Units and shares of Stock issued in settlement of the Restricted Stock Units do not constitute a public offering of securities under Hong Kong law and are available only to employees of the Corporation or its Affiliates. The Agreement, the Plan and other incidental communication materials have not been prepared in accordance with and are not intended to constitute a “prospectus” for a public offering of securities under the applicable securities legislation in Hong Kong.  The Restricted Stock Units are intended only for the personal use of each eligible employee of the Employer, the Corporation or an Affiliate and may not be distributed to any other person.

4. Wages.  The Restricted Stock Units and shares of Stock subject to the Restricted Stock Units do not form part of Participant’s wages for purposes of calculating any statutory or contractual payments under Hong Kong law.

22

Netherlands

1. Exclusion of Claim: Participant acknowledges and agrees that Participant will have no entitlement to compensation or damages insofar as such entitlement arises or may arise from Participant ceasing to have rights under the Plan, whether or not as a result of termination of Participant’s Service (whether such termination is in breach of contract or otherwise), or from the loss of diminution in value of the shares of Stock underlying the Restricted Stock Units. Upon the grant of the Restricted Stock Units, Participant shall be deemed to have waived irrevocably such entitlement.

Philippines

1. Settlement in Cash. Notwithstanding anything to the contrary in the Agreement, the Addendum or the Plan, the Restricted Stock Units shall be settled only in cash (and shall not be settled in shares of Stock), unless otherwise determined by the Corporation.

2. Reserved.

Singapore

1. Securities Law Information.  The grant of the Restricted Stock Units under the Plan is being made pursuant to the “Qualifying Person” exemption under section 273(1)(f) of the Securities and Futures Act (Chapter 289, 2006 Ed.) (“SFA”). The Plan has not been and will not be lodged or registered as a prospectus with the Monetary Authority of Singapore and is not regulated by any financial supervisory authority pursuant to any legislation in Singapore. Accordingly, statutory liability under the SFA in relation to the content of prospectuses would not apply.  Participant should note that the Restricted Stock Units are subject to section 257 of the SFA and Participant will not be able to make any subsequent sale of shares of Stock in Singapore, or any offer of such subsequent sale of shares of Stock subject to the Restricted Stock Units in Singapore, unless such sale or offer is made (i) after six (6) months from the Award Date or (ii) pursuant to the exemptions under Part XIII Division (1) Subdivision (4) (other than section 280) of the SFA.

Switzerland

1. Securities Law Information.  Neither the Agreement nor any other materials relating to the grant of Restricted Stock Units (a) constitutes a prospectus according to articles 35 et seq. of the Swiss Federal Act on Financial Services (“FinSA”), (b) may be publicly distributed or otherwise made publicly available in Switzerland to any person other than an employee of the Corporation or one of its Affiliates or (c) has been or will be filed with, approved or supervised by any Swiss reviewing body according to article 51 FinSA or any Swiss regulatory authority, including the Swiss Financial Market Supervisory Authority, FINMA.

23

United Kingdom (Including Northern Ireland)

1. Payment of Withholding Taxes.  The following provision supplements the section of the Agreement titled “Payment of Withholding Taxes”:

Without limitation to the section of the Agreement titled ‘Payment of Withholding Taxes’, Participant agrees that Participant is liable for all income tax and employee national insurance contributions or other social contributions or withholding taxes (“Tax-Related Items”) and hereby covenants to pay all such Tax-Related Items, as and when requested by the Corporation, the Employer or by Her Majesty’s Revenue and Customs (“HMRC”) (or any other tax authority or any other relevant authority). Participant also agrees to indemnify and keep indemnified the Corporation and the Employer against any Tax-Related Items that they are required to pay or withhold or have paid or will pay on Participant’s behalf to HMRC (or any other tax authority or any other relevant authority).

Notwithstanding the foregoing, if Participant is a director or executive officer (as within the meaning of Section 13(k) of the U.S. Securities Exchange Act of 1934, as amended), the terms of the immediately foregoing provision will not apply. In the event that Participant is a director or executive officer and income tax due is not collected from or paid by Participant within 90 days after the U.K. tax year in which an event giving rise to the indemnification described above occurs, the amount of any uncollected tax may constitute a benefit to Participant on which additional income tax and national insurance contributions may be payable. Participant acknowledges that Participant ultimately will be responsible for reporting and paying any income tax due on this additional benefit directly to HMRC under the self-assessment regime and for reimbursing the Corporation or the Employer (as applicable) for the value of any employee national insurance contributions due on this additional benefit, which the Corporation and/or the Employer may recover from Participant at any time thereafter by any of the means referred to in section of the Agreement titled “Payment of Withholding Taxes”.

2. Exclusion of Claim.  Participant acknowledges and agrees that Participant will have no entitlement to compensation or damages insofar as such entitlement arises or may arise from Participant’s ceasing to have rights under or to be entitled to the Restricted Stock Units, whether or not as a result of termination of Service (whether such termination is in breach of contract or otherwise), or from the loss or diminution in value of the Restricted Stock Units.  Upon the award of the Restricted Stock Units, Participant shall be deemed irrevocably to have waived any such entitlement.

3. Section 2 of the Addendum.  Section 2 of the Addendum (Participants in the European Union) shall not apply to the Restricted Stock Units.

Basis of Presentation

These interim unaudited condensed consolidated financial statements have been prepared in accordance with GAAP as established by FASB for interim financial information and with the instructions to Form 10-Q and should be read in conjunction with the consolidated financial statements and notes thereto contained in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022. The results of operations for interim periods are not necessarily indicative of the results of operations for the full year.

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosures of contingent assets and liabilities, and reported amounts of revenues and expenses. On an ongoing basis, management evaluates its estimates based upon historical experience, observance of trends, information available from outside sources and various other assumptions that management believes to be reasonable under the circumstances. Actual results may differ from these estimates under different conditions or assumptions.

In the opinion of management, all adjustments (consisting of normal recurring adjustments) considered necessary for a fair presentation of financial position, results of operations and cash flows at the dates and for the periods presented have been included.

Segment Information

The Company operates six reportable business segments: Options, North American Equities, Europe and Asia Pacific, Futures, Global FX, and Digital which is reflective of how the Company's chief operating decision-maker reviews and operates the business. See Note 14 (“Segment Reporting”) for more information.

Update to Significant Accounting Policies

With the exception of the change for the accounting of margin deposits, clearing funds, and interoperability funds discussed below, there have been no new or material changes to the significant accounting policies discussed for the Company for the nine-month period ended September 30, 2023, that are of significance, or potential significance, to the Company.

Margin Deposits, Clearing Funds, and Interoperability Funds

Due to an update in its rules, effective August 14, 2023, Cboe Clear Europe may invest interoperability fund deposits provided by clearing participants subsequent to the effective date of the rules change. In accordance with the updated policy, Cboe Clear Europe has the option to maintain cash deposits provided by clearing participants at Clearstream Banking S.A., in the same manner done previously, or invest the cash in certain investments within the parameters of its investment policy. As such, the interoperability fund deposits are reflected in the condensed consolidated balance sheet as of the effective date of the rules change. Changes in margin deposits, clearing funds, and interoperability funds, are presented net in the “restricted cash and cash equivalents and customer bank deposits (included in margin deposits, clearing funds, and interoperability funds)” line in the operating section of the condensed consolidated statement of cash flows. Similarly, cash flows associated with related investment agreements as well as interest income earned on such investments will be classified as cash flows from operating activities in the condensed consolidated statement of cash flows. Both activities are part of Cboe Clear Europe’s principal operating activities and are presented within the operating section of the condensed consolidated statement of cash flows.

When investments are made in accordance with the Regulation Investment Policy, Cboe Clear Europe receives the amount of investment earnings and pays clearing participants those earnings minus a set basis point cost of collateral. Related interest income and interest expense are presented gross in the condensed consolidated statement of income in other revenue and other cost of revenue, respectively, as it relates to a core operating activity of Cboe Clear Europe.

REVENUE RECOGNITION

REVENUE RECOGNITION

2.   REVENUE RECOGNITION

The Company presents three financial statement revenue captions within its condensed consolidated statements of income that reflect the Company’s diversified products, expansive geographical reach, and overall business strategy. Below is a summary of the Company’s financial statement revenue captions:

Revenues

● Cash and spot markets – includes associated transaction and clearing fees, the portion of market data fees relating to associated U.S. tape plan market data fees, associated regulatory fees, and associated other revenue from Cboe’s North American Equities, Europe and Asia Pacific, Global FX, and Digital segments.

● Data and access solutions – includes access and capacity fees, proprietary market data fees, and associated other revenue across Cboe’s six segments.

● Derivatives markets – includes associated transaction and clearing fees, the portion of market data fees relating to associated U.S. tape plan market data fees, associated regulatory fees, and associated other revenue from Cboe’s Options, Futures, Europe and Asia Pacific, and Digital segments.

The Company’s main types of revenue contracts consist of the following, which are disaggregated from the condensed consolidated statements of income.

● Transaction and clearing fees – Transaction fees represent fees charged by the Company for meeting the point-in-time performance obligation of executing a trade on its markets. These fees can be variable based on trade volume tiered discounts; however, as all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Transaction fees are recognized across all segments. Clearing fees, which include settlement fees, represent fees charged by the Company for meeting the point-in-time performance obligation for transactions cleared and settled by Cboe Clear Europe and Cboe Clear Digital, the derivatives clearing organization for Cboe Digital. Clearing fees can be variable based on trade volume tiered discounts; however, as

all tiered discounts are calculated monthly, the actual discount is recorded on a monthly basis. Clearing fees are recognized in the Europe and Asia Pacific and Digital segments. Transaction and clearing fees, as well as any tiered volume discounts, are calculated and billed monthly in accordance with the Company’s published fee schedules.

● Access and capacity fees – Access and capacity fees represent fees assessed for the opportunity to trade, including fees for trading-related functionality across all segments, terminal and other equipment rights, maintenance services, trading floor space and telecommunications services. Facilities, systems services and other fees are generally monthly fee-based. These fees are billed monthly in accordance with the Company’s published fee schedules and recognized on a monthly basis when the performance obligations are met. All access and capacity fees associated with the trading floor are recognized over time in the Options segment, as the performance obligations are met.

● Market data fees – Market data fees represent the fees received by the Company from the U.S. tape plans and fees charged to customers for proprietary market data. Fees from the U.S. tape plans are collected monthly based on published fee schedules and distributed quarterly to the Exchanges based on a known formula. A contract for proprietary market data is entered into and charged on a monthly basis in accordance with the Company’s published fee schedules as the service is provided. Proprietary market data also includes revenue from various licensing agreements. Both types of market data are satisfied over time, and revenue is recognized on a monthly basis as the customer receives and consumes the benefit as the Company provides the data to meet its performance obligation. U.S. tape plan market data is recognized in the North American Equities and Options segments. Proprietary market data fees are recognized across all segments.

● Regulatory fees – There are two types of regulatory fees that the Company recognizes. The first type represents fees collected by the Company to cover the Section 31 fees charged to the Exchanges by the SEC for meeting the point-in-time performance obligation of executing a trade on its markets. The fees charged to customers are based on the fee set by the SEC per notional value of U.S. Equities exchange transactions and per round turn of Options transactions executed on the Company’s U.S. securities markets. These fees are calculated and billed monthly and are recognized in the North American Equities and Options segments. As the Exchanges are responsible for the ultimate payment to the SEC, the Exchanges are considered the principal in these transactions. Regulatory fees also include the options regulatory fee (“ORF”) which supports the Company’s regulatory oversight function in the Options segment, along with other miscellaneous regulatory fees, and neither can be used for non-regulatory purposes. The ORF and miscellaneous fees are recognized when the performance obligation is fulfilled.

● Other revenue – Other revenue primarily includes interest income on investments (including from investments of interoperability fund deposits) from clearing operations, all fees related to the trade reporting facility operated in the Europe and Asia Pacific segment, listing fees, and revenue associated with advertisements through the Company’s websites.

All revenue recognized in the condensed consolidated statements of income is considered to be revenue from contracts with customers, with the exception of interest income from clearing operations.

3.   ACQUISITIONS

On May 2, 2022, the Company purchased ErisX, which was subsequently rebranded to Cboe Digital. Cboe Digital operates a U.S. based digital asset spot market, a regulated futures exchange and a regulated clearinghouse. Ownership of Cboe Digital allows the Company to enter the digital asset spot and derivatives marketplaces through a digital-first platform developed with industry partners to focus on robust regulatory compliance, data and transparency. Eris Innovations Holdings, LLC (formerly Eris Exchange Holdings, LLC) was not a part of this transaction and the Company retains its minority equity ownership interest in Eris Innovations Holdings, LLC. Of the acquisition’s purchase price, $460.9 million was allocated to goodwill, $95.0 million was allocated to intangible assets, and $8.4 million was allocated to working capital. Prior to signing the acquisition agreement, the Company held a minority investment in ErisX. As a result of the acquisition of the remaining portion of ErisX, the Company recognized a $7.5 million gain, reflecting the change in fair value of the minority investment in ErisX as a result of the acquisition, which is included in other income (expense), net in the condensed consolidated statement of income for the year ended December 31, 2022. See below for further discussion of intangible assets acquired. Additionally, the Company performed impairment testing during the year ended December 31, 2022, as there were market events that indicated it was more likely than not that these assets were impaired, resulting in the recognition of impairment charges to goodwill. See Note 8 (“Goodwill, Intangible Assets, Net, and Digital Assets Held”) for more information on the impairments.

On June 1, 2022, the Company purchased NEO, which was subsequently rebranded to Cboe Canada. Cboe Canada is a fintech organization that is comprised of a fully registered Canadian securities exchange with a diverse product and services set ranging from corporate listings to cash equities trading and a non-listed securities distribution platform. With ownership of Cboe Canada, the Company expects to further grow Canada as a hub for global equities trading, in addition to MATCHNow, the ATS acquired by the Company in 2020. As of December 31, 2022, the allocation of purchase price includes adjustments within the measurement period resulting in a decrease to intangible assets, an increase in net working capital and a reduction in contingent consideration. See the table below for more information about the adjustments made to the Cboe Canada (formerly NEO) purchase price allocation. See below for further discussion of intangible assets acquired and Note 13 (“Fair Value Measurement”) for the impact of the allocation adjustments on the Company’s financial liabilities.

The following table presents the details of the adjustments made to the initial purchase price allocation for the Cboe Canada (formerly NEO) acquisition during the year ended December 31, 2022 (in millions):

	Initial purchase		Total		Adjusted purchase

Acquisition-related costs relate to acquisitions and other strategic opportunities. The Company expensed $0.8 million and $1.6 million of acquisition-related costs during the three months ended September 30, 2023 and 2022, respectively, all of which related to professional fees and other expenses. These acquisition-related expenses are included in acquisition-related costs in the condensed consolidated statements of income.

The Company expensed $7.9 million and $17.9 million of acquisition-related costs during the nine months ended September 30, 2023 and 2022, respectively, all of which related to professional fees and other expenses.

Equity Method Investments

The Company’s investment in the 7Ridge Investments 3 LP (“7Ridge Fund”), represents a nonconsolidated variable interest entity (“VIE”). The Company has determined that consolidation of the VIE is not required as the Company is not the primary beneficiary of the 7Ridge Fund, as it does not have controlling financial interest and lacks the ability to unilaterally remove the general partner, 7Ridge Investments 3 GP Limited, direct material strategic decisions, or dissolve the entity (i.e., the Company does not have unilateral substantive “kick-out” or “liquidation” rights).

The Company’s interest in the 7Ridge Fund is equal to the carrying value of the investment as of September 30, 2023, or $288.8 million, which includes periodic capital contributions to the 7Ridge Fund, as well as the Company’s share of 7Ridge Fund’s profit or loss, including gains or losses arising from the fair value measurement of the investment held by the 7Ridge Fund, booked against the investment account. The carrying value of the investment is included in

investments within the condensed consolidated balance sheets. The Company’s maximum loss exposure, in the unlikely event that all of the VIE’s assets become worthless, is limited to the carrying value of the Company’s investment.

Other Equity Investments

The carrying value of other equity investments is included in investments in the condensed consolidated balance sheets. The Company accounts for these investments using the measurement alternative given the absence of readily determinable fair values for the respective investments and due to the Company’s inability to exercise significant influence over the investments based upon the respective ownership interests held. As of September 30, 2023, other equity investments primarily consist of minority investments in Eris Innovations Holdings, LLC, Globacap Technology Limited, CSD Br, Coin Metrics Inc., Cboe Vest Financial Group, Inc., Effective Investing Limited, and a 20% investment in OCC.

Effective July 27, 2023, the Company entered into an agreement to sell its former headquarters building with a tentative close date in the fourth quarter of 2023, subject to customary closing conditions. The Company classified the associated land, building, and certain furniture and equipment of the former headquarters location as held for sale, performed an impairment assessment, and ceased depreciation effective August 1, 2023, as the Company anticipates selling the property held for sale in less than twelve months. In connection with the sale, the Company anticipates providing seller financing to the purchaser in the form of a promissory note for a portion of the purchase price of the former headquarters. As of September 30, 2023, the total value of the property held for sale on the condensed consolidated balance sheet was $8.7 million. The impact of ceasing depreciation of the property held for sale did not result in a material impact to the condensed consolidated financial statements.

CREDIT LOSSES

CREDIT LOSSES

CREDIT LOSSES

6. CREDIT LOSSES

Current expected credit losses are estimated for accounts receivable and certain notes receivable.

Accounts receivable represent amounts due from the Company’s member firms. The allowance for accounts receivable credit losses is calculated using an aging schedule.

The allowance for notes receivable credit losses is associated with notes receivable included within other assets, net on the condensed consolidated balance sheets and relates to promissory notes to fund the implementation and operation of the consolidated audit trail (“CAT”), which notes are to be repaid by Consolidated Audit Trail, LLC (“CATLLC”). CAT involves the creation of an audit trail that is required by SEA Rule 613, and it strives to enhance regulators’ ability to monitor trading activity in the U.S. markets through a phased implementation. CATLLC is a national market system plan that was created by self-regulatory organizations that include the Company’s six Exchanges, the other U.S. national securities exchanges and FINRA (who collectively are referred to as the “Plan Participants”) to implement and operate the CAT. The funding of the CAT’s implementation and operations is ultimately expected to be provided by Plan Participants and by broker-dealers (who are referred to as “Industry Members”). However, the funding to date has solely been provided to CATLLC by the Plan Participants in exchange for promissory notes.

On September 6, 2023, the SEC issued an order approving an amendment to the CAT national market system plan to implement a revised funding model (“CAT Funding Model”) for CATLLC to fund the CAT. The approved CAT Funding Model contemplates two categories of CAT fees calculated based on the “executed equivalent shares” of transactions in eligible securities: (i) CAT fees assessed by CATLLC to Industry Members who are CAT Executing Brokers (as that term is defined in the CAT national market system plan) to recover a portion of historical CAT costs previously paid to CATLLC by the Plan Participants; and (ii) CAT fees assessed by CATLLC to CAT Executing Brokers and Plan Participants to fund prospective CAT costs. The Plan Participants will file fee filings with the SEC to implement the applicable transaction-based fee rates that are to be assessed by CATLLC to CAT Executing Brokers for each CAT fee. Initially, CATLLC plans to implement a CAT fee related to a portion of historical CAT costs incurred prior to 2022. The funds generated from the assessment of that CAT fee will be used by CATLLC to repay a portion of the promissory notes to the Plan Participants. Additional CAT fees related to other historical CAT costs and to prospective CAT costs are planned to be introduced at a later time. Once the CAT fee related to ongoing prospective CAT costs becomes effective through fee filings submitted by the Plan Participants, it is anticipated there will no longer be any need for promissory notes to be provided by the Plan Participants to CATLLC.

A challenge to the SEC’s September 6, 2023 order was filed by the American Securities Association and Citadel Securities, LLC against SEC before the U.S. Court of Appeals for the 11th Circuit on October 17, 2023. This challenge or any other challenge to the SEC order approving the CAT Funding Model and/or Plan Participant(s) fee filings may significantly delay implementation efforts. As a result, the Plan Participants may continue to incur additional significant costs, and/or it may result in them not being able to collect on the promissory notes related to the funding of the implementation and operation of the CAT.

Until the fees for historical CAT costs that are associated with the promissory notes are collected from CAT Executing Brokers and remitted by CATLLC to the Plan Participants, the Plan Participants may continue to incur additional significant costs, including additional promissory notes to fund CAT. The allowance for notes receivable credit losses associated with the CAT is calculated using a methodology that is primarily based on the structure of the notes and various potential outcomes under the CAT Funding Model.

The following represents the changes in allowance for credit losses during the nine months ended September 30, 2023 (in millions):

	Balance at December 31, 2022		Current period provision for expected credit losses		Write-offs charged against the allowance		Recoveries collected		Balance at September 30, 2023

Goodwill has been allocated to specific reporting units for purposes of impairment testing - Options, North American Equities, Europe and Asia Pacific, and Global FX. No goodwill has been allocated to Futures. See below for further details on Cboe Digital’s goodwill. Goodwill impairment testing is performed annually in the fiscal fourth quarter or more frequently if conditions exist that indicate that the asset may be impaired.

Following the acquisition of Cboe Digital, which closed on May 2, 2022, in the quarter ended June 30, 2022, negative events and trends in the broader digital asset environment emerged, such as deleveraging and bankruptcies, and certain negative trends in the broader digital asset environment that started in late 2021 intensified, such as the decline in digital asset prices, overall market activity, and market capitalization. Additionally, following the acquisition of Cboe Digital, the efforts to syndicate minority ownership interests in Cboe Digital to potential investors during the quarter ended June 30, 2022 became more challenging, and the outlook for the Digital segment’s future market growth was negatively impacted. The Company considered these developments, in particular the syndication efforts during the quarter ended June 30, 2022, to be potential indications of impairment and performed an interim impairment test for the goodwill recognized in the Digital reporting unit during the quarter ended June 30, 2022. The Company concluded that the carrying value of the reporting unit exceeded its estimated fair value, which considered both market and income approaches, and recorded a goodwill impairment charge of $460.1 million in the condensed consolidated statements of income during the quarter ended June 30, 2022, and also recognized a deferred tax asset of $116.2 million. This deferred tax asset, resulting from the excess of tax-deductible goodwill over book goodwill, relates to future tax deductions the Company expects to realize to reduce potential tax payments on future income. As a result, the carrying value of Cboe Digital decreased by $343.9 million, to $220.0 million as of June 30, 2022. The Company also performed an impairment assessment over the intangible assets recognized as a result of the Cboe Digital acquisition during the quarter ended June 30, 2022, and based on the results of the assessments, determined there was no impairment required as the fair value approximated the carrying value. No other long lived assets were recognized as a result of the acquisition.

As a result of the finalization of the net working capital calculation associated with the acquisition of Cboe Digital during the quarter ended September 30, 2022, the Company recorded additional goodwill of $0.8 million. Subsequently, the Company concluded that the indicators of impairment outlined in the previous paragraph continued to be relevant and recorded an additional goodwill impairment charge of $0.8 million in the condensed consolidated statements of income for the three months ended September 30, 2022. The Company determined there were no further impairment indicators for the nine months ended September 30, 2023.

Term Loan Agreement

On March 22, 2018, the Company entered into a Term Loan Credit Agreement (the “Term Loan Agreement”). The Term Loan Agreement matures on December 15, 2023 and initially provided for a senior unsecured term loan facility in an aggregate principal amount of $300 million, which amount was later increased to allow for an additional draw of $110 million on June 25, 2021 in order to fund a portion of the acquisition of Cboe Asia Pacific (formerly Chi-X Asia Pacific Holdings Limited) and was increased on March 29, 2022 to allow for additional delayed draws of $190 million on April 29, 2022 to fund a portion of the Cboe Digital (formerly ErisX) acquisition, and $175 million on May 31, 2022 to fund a portion of the Cboe Canada (formerly NEO) acquisition. On each of August 25, 2022 and September 22, 2022, the Company repaid $50 million, respectively, of outstanding indebtedness under the Term Loan Agreement, and on each of November 1, 2022, December 1, 2022, and December 27, 2022, the Company repaid $40 million, $50 million, and $30 million, respectively, of outstanding indebtedness under the Term Loan Agreement totaling $220 million repaid during the year ended December 31, 2022. On May 12, 2023, June 21, 2023 and September 28, 2023, the Company repaid $65 million, $75 million, and $90 million respectively, of outstanding indebtedness under the Term Loan Agreement totaling $230 million repaid during the nine months ended September 30, 2023.

Loans under the Term Loan Agreement bear interest, at the Company’s option, at either (i) the Secured Overnight Financing Rate (“SOFR”) as administered by the Federal Reserve Bank of New York (or a successor administrator) plus a margin of 0.65 percent per annum or (ii) a daily floating rate based on the agent’s prime rate (subject to certain minimums based upon the federal funds effective rate or SOFR) plus a margin of 0.50 percent per annum.

The Term Loan Agreement contains customary representations, warranties, and affirmative and negative covenants for facilities of its type, including financial covenants, events of default, including cross-defaults from the Company’s other indebtedness, and indemnification provisions in favor of the lenders thereunder. The negative covenants include restrictions regarding the incurrence of liens, the incurrence of indebtedness by the Company’s subsidiaries and fundamental changes, subject to certain exceptions in each case. The financial covenants require the Company to meet a quarterly financial test with respect to a minimum consolidated interest coverage ratio of not less than 4.00 to 1.00 and a maximum consolidated leverage ratio of not greater than 3.50 to 1.00; provided that the consolidated leverage ratio may, subject to certain triggering events set forth in the Term Loan Agreement, be increased to 4.25 to 1.00 or 4.00 to 1.00 (from 3.50 to 1.00) for four consecutive fiscal quarters following certain acquisitions, provided this increase may be made only once and at the time it exercises such financial covenant step-up, the Company shall be exercising a like step-up under its revolving credit facility. At September 30, 2023, the Company was in compliance with these covenants and did not exercise financial covenant step-up.

Senior Notes

On January 12, 2017, the Company entered into an indenture (the “Indenture”), by and between the Company and Computershare Trust Company, N.A. (as successor to Wells Fargo Bank, National Association), as trustee, in connection with the issuance of $650 million aggregate principal amount of the Company’s 3.650% Senior Notes due 2027 (“3.650% Senior Notes”). The form and terms of the 3.650% Senior Notes were established pursuant to an Officer’s Certificate, dated as of January 12, 2017, supplementing the Indenture. The Company used a portion of the net proceeds from the 3.650% Senior Notes to fund, in part, the Merger, including the payment of related fees and expenses and the repayment of Bats’ existing indebtedness, and the remainder for general corporate purposes. The 3.650% Senior Notes mature on January 12, 2027 and bear interest at the rate of 3.650% per annum, payable semi-annually in arrears on January 12 and July 12 of each year, commencing July 12, 2017.

On December 15, 2020, the Company issued $500 million aggregate principal amount of 1.625% Senior Notes due 2030 ("1.625% Senior Notes"). The form and terms of the 1.625% Senior Notes were established pursuant to an Officer’s Certificate, dated as of December 15, 2020, supplementing the Indenture. The Company used the net proceeds from the 1.625% Senior Notes to finance the acquisition of BIDS Trading, repay a portion of amounts outstanding under the term loan facility and all outstanding indebtedness under the revolving credit facility and the remainder for general corporate purposes, which may include the financing of future acquisitions or the repayment of other outstanding indebtedness. The 1.625% Senior Notes mature on December 15, 2030 and bear interest at the rate of 1.625% per annum, payable semi-annually in arrears on June 15 and December 15 of each year, commencing June 15, 2021.

On March 16, 2022, the Company issued $300 million aggregate principal amount of 3.000% Senior Notes due 2032 (“3.000% Senior Notes” and, together with the 1.625% Senior Notes and the 3.650% Senior Notes, the “Senior Notes”). The form and terms of the 3.000% Senior Notes were established pursuant to an Officer’s Certificate, dated as of March 16, 2022, supplementing the Indenture. The Company used the net proceeds from the 3.000% Senior Notes, together with cash on hand, and the proceeds of additional borrowings, to partially fund its acquisition of Cboe Digital. The 3.000% Senior Notes mature on March 16, 2032 and bear interest at the rate of 3.000% per annum, payable semi-annually in arrears on March 16 and September 16 of each year, commencing September 16, 2022.

The Senior Notes are unsecured obligations of the Company and rank equally with all of the Company’s other existing and future unsecured, senior indebtedness, but are effectively junior to the Company’s secured indebtedness, to the extent of the value of the assets securing such indebtedness, and will be structurally subordinated to the secured and unsecured indebtedness of the Company’s subsidiaries.

The Company has the option to redeem some or all of the Senior Notes, at any time in whole or from time to time in part, at the redemption prices set forth in the applicable Officer’s Certificate. The Company may also be required to offer to repurchase the Senior Notes upon the occurrence of a Change of Control Triggering Event (as such term is defined in the applicable Officer’s Certificate) at a repurchase price equal to 101 percent of the aggregate principal amount of Senior Notes to be repurchased.

Indenture

Under the Indenture, the Company may issue debt securities, which includes the Senior Notes, at any time and from time to time, in one or more series without limitation on the aggregate principal amount. The Indenture governing the Senior Notes contains customary restrictions, including a limitation that restricts the Company’s ability and the ability of certain of the Company’s subsidiaries to create or incur secured debt. Such Indenture also limits certain sale and

leaseback transactions and contains customary events of default. At September 30, 2023, the Company was in compliance with these covenants.

Revolving Credit Agreement

On February 25, 2022, the Company entered into a Second Amended and Restated Credit Agreement (the “Revolving Credit Agreement”), which amended and restated the prior revolving credit agreement.

The Revolving Credit Agreement provides for a senior unsecured $400 million three-year revolving credit facility (the “Revolving Credit Facility”) that includes a $25 million swing line sub-facility. The Company may also, subject to the agreement of the applicable lenders, increase the commitments under the Revolving Credit Facility by up to $200 million, for a total of $600 million. Subject to specified conditions, the Company may designate one or more of its subsidiaries as additional borrowers under the Revolving Credit Agreement provided that the Company guarantees all borrowings and other obligations of any such subsidiaries under the Revolving Credit Agreement. As of September 30, 2023, no subsidiaries were designated as additional borrowers.

Funds borrowed under the Revolving Credit Agreement may be used to fund working capital and for other general corporate purposes, including the making of any acquisitions the Company may pursue in the ordinary course of its business. As of September 30, 2023, no borrowings were outstanding under the Revolving Credit Agreement. Accordingly, at September 30, 2023, $400 million of borrowing capacity was available for the purposes permitted by the Revolving Credit Agreement.

Loans under the Revolving Credit Agreement will bear interest, at the Company’s option, at either (i) the Relevant Rate (defined herein) plus a margin (based on the Company’s public debt ratings) ranging from 0.75 percent per annum to 1.25 percent per annum or (ii) a daily fluctuating rate based on the administrative agent’s prime rate (subject to certain minimums based upon the federal funds effective rate or Term SOFR), which is subject to a 1 percent floor, plus a margin (based on the Company’s public debt ratings) ranging from zero percent per annum to 0.25 percent per annum. “Relevant Rate” means with respect to any committed borrowing or swingline borrowing denominated in (a) Dollars, Term SOFR plus a spread adjustment of 0.10 percent per annum, (b) Sterling, SONIA plus a spread adjustment of 0.0326 percent per annum and (c) Euros, EURIBOR, as applicable, provided that each Relevant Rate is subject to a 0 percent floor.

Subject to certain conditions stated in the Revolving Credit Agreement, the Company and any subsidiaries designated as additional borrowers may borrow, prepay and reborrow amounts under the Revolving Credit Facility at any time during the term of the Revolving Credit Agreement. The Revolving Credit Agreement will terminate and all amounts owing thereunder will be due and payable on February 25, 2027, unless the commitments are terminated earlier, either at the request of the Company or, if an event of default occurs, by the lenders (or automatically in the case of certain bankruptcy-related events). The Revolving Credit Agreement contains customary representations, warranties, and affirmative and negative covenants for facilities of its type, including financial covenants, events of default and indemnification provisions in favor of the lenders. The negative covenants include restrictions regarding the incurrence of liens, the incurrence of indebtedness by the Company’s subsidiaries and fundamental changes, subject to certain exceptions in each case. The financial covenants require the Company to meet a quarterly financial test with respect to a minimum consolidated interest coverage ratio of not less than 4.00 to 1.00 and a maximum consolidated leverage ratio of not greater than 3.50 to 1.00; provided that the consolidated leverage ratio may, subject to certain triggering events set forth in the Revolving Credit Agreement, be increased to 4.25 to 1.00 on one occasion and 4.00 to 1.00 on another occasion, in each case, for four consecutive fiscal quarters; provided that, prior to the exercise of the second such financial covenant step-up, the maximum consolidated leverage ratio shall have returned to a level of 3.50 to 1.00 for at least two consecutive fiscal quarters. At September 30, 2023, the Company was in compliance with these covenants and did not exercise financial covenant step-up.

Cboe Clear Europe Credit Facility

On July 1, 2020, EuroCCP (subsequently rebranded to Cboe Clear Europe), as borrower, the Company, as guarantor, entered into a Facility Agreement (as subsequently amended and restated, the “Facility” or “Cboe Clear Europe Credit Facility”) with Bank of America Merrill Lynch International Designated Activity Company, as co-ordinator, facility agent, lender, sole lead arranger and sole bookrunner, Citibank N.A., as security agent, and certain other lenders named therein. The Facility was amended and restated, on July 1, 2021, June 30, 2022, and June 29, 2023, as described below.

The Facility provides for a €1.25 billion committed syndicated multicurrency revolving and swingline credit facility (i) that is available to be drawn by Cboe Clear Europe towards (a) financing unsettled amounts in connection with the settlement of transactions in securities and other items processed through Cboe Clear Europe’s clearing system and (b) financing any other liability or liquidity requirement that Cboe Clear Europe incurred in the operation of its clearing system and (ii) under which the scheduled interest and fees on borrowings (but not the principal amount of any borrowings) are guaranteed by the Company. Subject to certain conditions, Cboe Clear Europe is able to increase the commitments under the Facility by up to €500 million, to a total of €1.75 billion.

Borrowings under the Facility are secured by cash, eligible government bonds and eligible equity assets deposited by Cboe Clear Europe into secured accounts. In addition, Cboe Clear Europe must ensure that at all times the aggregate of (a) each clearing participant’s contribution to the relevant clearing fund, (b) each clearing participant’s margin amount and (c) any cash equities purchased using the proceeds of the assets described in (a) and (b), less the amount of any such clearing participant contribution, margin amount or cash equities which have been transferred to (or secured in favor of) any provider of settlement or custody services to Cboe Clear Europe, is not less than €500 million.

Borrowings under the Facility’s revolving loans and non-U.S. dollar swingline loans bear interest at the relevant floating base rate plus a margin of 1.60 percent per annum and (subject to certain conditions) borrowings under the Facility’s U.S. dollar swingline loans bear interest as the higher of the relevant agent’s prime commercial lending rate for U.S. dollars and 0.5 percent per annum over the federal funds effective rate. A commitment fee of 0.275 percent per annum is payable on the unused and uncalled amount of the Facility during the availability period.

Subject to certain conditions stated in the Facility, Cboe Clear Europe may borrow, prepay and reborrow amounts under the Facility at any time during the term of the Facility. The Facility will terminate and all amounts owing thereunder will be due and payable on June 28, 2024, unless the commitments are terminated earlier, either at the request of Cboe Clear Europe or, if an event of default occurs, by the Lenders (or automatically in the case of certain bankruptcy-related events).

The Facility contains customary representations, warranties and covenants for facilities of its type, including events of default of the Company and Cboe Clear Europe and indemnification provisions in favor of the Lenders. In particular, the covenants include restrictions regarding the incurrence of liens by Cboe Clear Europe and its subsidiaries, and an event of default will be triggered if Cboe Clear Europe ceases its business, subject to certain exceptions in each case. There is also a requirement for the net worth of (a) the Company to be no less than $1.75 billion on the date of each drawdown and delivery of compliance certificates and (b) Cboe Clear Europe to be the higher of €30 million and any such amount required for Cboe Clear Europe to meet minimum liquidity regulations under applicable regulation at all times.

As of September 30, 2023, no borrowings were outstanding under the Facility. Accordingly, at September 30, 2023, €1.25 billion of borrowing capacity was available for the purposes permitted by the Facility. At September 30, 2023, the Company and Cboe Clear Europe were in compliance with applicable covenants.

Small Business Administration’s Paycheck Protection Program

On May 1, 2020, prior to Cboe’s acquisition of Cboe Digital, Cboe Digital (formerly ErisX) received $1.3 million of proceeds from a loan issued under either the Small Business Administration ("SBA") Paycheck Protection Program ("PPP") under section 7(a)(36) of the Small Business Act or the SBA's Paycheck Protection Program Second Draw Loans under Section 7(a)(37) of the SBA. On May 26, 2022, the PPP loan was forgiven and no further balance is due.

Cboe Clear Europe clears equities from eighteen European markets and the United States, as well as Depositary Receipts, ETFs, and exchange traded currencies (“ETCs”). In September 2021 Cboe Clear Europe began clearing equity index derivatives for ten European markets. Through a novation process, Cboe Clear Europe becomes the buyer for every seller and the seller for every buyer, thereby protecting clearing participants from counterparty risk and allowing the settlement of trades in the event of a clearing participant default.

Cboe Clear Europe only assumes the guarantor role if it has an equal and offsetting claim against a clearing participant. For the period ended September 30, 2023, there have been no events of default for which a liability is required to be recognized in accordance with GAAP.

Clearing Participant Deposits

Cboe Clear Europe generally requires all clearing participants to deposit collateral to help mitigate Cboe Clear Europe’s exposure to credit risk in the event that a clearing participant fails to meet a financial or contractual obligation.

Margin Deposits

Margin deposits, which are predominately in the form of cash and cash equivalents, are deposits made by each clearing participant to Cboe Clear Europe to cover some or all of the credit risk of its failure to fulfill its obligations in the trade. Cboe Clear Europe maintains and manages all cash deposits related to margin deposits. Substantially all risks and rewards of margin deposit ownership, including net interest income, belong to Cboe Clear Europe and are recorded in cash and spot markets on the condensed consolidated statements of income. In the event of a default, Cboe Clear Europe can access the defaulting participant’s margin deposits to cover the defaulting participant’s losses. For more information, see “Default and Liquidity Waterfalls” below.

Clearing Funds

The clearing fund mutualizes the risk of default among all clearing participants. Depending on their membership, clearing participants contribute to the cash-equity and/or derivatives segment of the clearing fund. Although the entire clearing fund is available to cover potential losses in the event that the margin deposits and the clearing fund deposits of a defaulting clearing participant are inadequate to fulfill that clearing participant’s outstanding financial obligations, the clearing fund first uses the product class segment of the Clearing Fund in which the defaulting participants was active (see “Default and Liquidity Waterfalls” below). In the event of a default, Cboe Clear Europe is generally required to liquidate the defaulting clearing participant’s open positions. To the extent that the positions remain open, Cboe Clear Europe is required to assume the defaulting clearing participant’s obligations related to the open positions. Clearing participants are required to make contributions to the clearing fund that are proportional to their risk exposure in the form of cash or non-cash contributions, which generally consist of highly liquid securities.

Interoperability Fund

For the cash equity business line, Cboe Clear Europe has entered into interoperable arrangements with two other central counterparties (“CCPs”). Under these arrangements, margin is pledged to and from interoperable CCPs. The interoperability fund consists of collateral provided by clearing participants that is pledged by Cboe Clear Europe to the other interoperable CCPs, to cover margin calls Cboe Clear Europe receives from such interoperable CCPs.

As described in Note 1 (“Organization and Basis of Presentation”), effective August 14, 2023, Cboe Clear Europe enacted changes to its rules, and is able to invest the cash collateral received in the form of interoperability fund deposits from clearing participants in certain investments, typically securities issued by pre-approved sovereign issuers and reverse repurchase agreements with overnight maturities. When investments are made in accordance with the Regulation Investment Policy, Cboe Clear Europe receives the amount of investment earnings and pays clearing participants those earnings minus a set basis point cost of collateral. As Cboe Clear Europe is able to direct the investment of the cash interoperability fund deposits received from the clearing participants within the program parameters and receives an economic benefit from those investments, these amounts are included in the Margin Deposits, Clearing Funds, and Interoperability fund captions in the condensed consolidated balance sheets and the related interest income and expense is recorded in other revenue and other costs of revenue respectively on the condensed consolidated statements of income.

The details of our margin deposits, clearing funds, and interoperability funds as of September 30, 2023 and December 31, 2022, are as follows (in millions):

	September 30, 2023
	Margin Deposits		Clearing Funds		Interoperability Funds
Central bank account	$	496.0	$	88.9	$	345.9
Reverse repurchase and other		71.5		4.1		302.5
Cash contributions		567.5		93.0		648.4
Non-cash contributions (1)		426.0		44.3		241.3
Total	$	993.5	$	137.3	$	889.7

	December 31, 2022
	Margin Deposits		Clearing Funds		Interoperability Funds (2)
Cash contributions	$	426.9	$	103.4	$	376.0
Non-cash contributions (1)		338.2		38.6		89.3
Total	$	765.1	$	142.0	$	465.3

(1) These amounts are not reflected in the condensed consolidated balance sheets, as Cboe Clear Europe does not have the ability to sell or repledge the amounts absent a clearing participant default.

(2) The interoperability funds were not reflected in the condensed consolidated balance sheet as of December 31, 2022, as Cboe Clear Europe did not have the ability to invest the balances at that point in time. See the updated rule change discussed in Note 1 (“Organization and Basis of Presentation”) for additional information.

Default and Liquidity Waterfalls

The default waterfall is the priority order in which the capital resources are expected to be utilized in the event of a default where the defaulting clearing participant’s collateral would not be sufficient to cover the cost to liquidate its portfolio. If a default occurs and the defaulting clearing participant’s collateral, including margin deposits and clearing fund deposits, are depleted, then additional capital is utilized in the following order:

● Cboe Clear Europe dedicated own resources: The Cboe Clear Europe default waterfall first utilizes its dedicated own resources in two forms and totaling 35% of Cboe Clear Europe capital requirements; the ‘first skin in the game’, equal to 25% of Cboe Clear Europe capital requirements before the use of clearing fund contributions described below and the ‘second skin in the game’, an amount between 10-25% of capital requirements as discussed in Note 16 (“Regulatory Capital”).

● Clearing fund: Second, the Cboe Clear Europe default waterfall utilizes traditional CCP risk mutualization, in the event that default losses fully exhaust Cboe Clear Europe’s dedicated own resources amount, whereby contributions applicable to a particular product class are applied first to any loss attributable to that product class.

● Pro rata contributions: Third, if the default losses caused cannot be covered by the first two layers, the non-defaulting clearing participants shall on demand make additional payments to Cboe Clear Europe on a pro rata basis in proportion to the amount of their clearing fund contributions to cover any such remaining losses, which is limited to an amount equal to twice their clearing fund contribution as established under Cboe Clear Europe’s rules and regulations. In this scenario, contributions applicable to a particular product class are first applied to any losses attributable to that product class.

In addition to the default waterfall, the liquidity waterfall is the priority order in which the liquidity resources are expected to be utilized for Cboe Clear Europe’s ordinary course business operations and in situations when additional liquidity resources and liquidity measures may be activated in case of a potential liquidity shortfall. Liquidity, intraday or overnight, is mainly required for securities settlement. In ordinary course business circumstances, liquidity resources include the collateral directly deposited with Cboe Clear Europe, FX swap arrangements, and reverse repurchase agreements, as well as the use of the Facility.

FAIR VALUE MEASUREMENT

FAIR VALUE MEASUREMENT

13.  FAIR VALUE MEASUREMENT

Fair value is the price that would be received upon the sale of an asset or paid upon the transfer of a liability in an orderly transaction between market participants at the measurement date and in the principal or most advantageous market for that asset or liability. The fair value should be calculated based on assumptions that market participants would use in pricing the asset or liability, not on assumptions specific to the entity. In addition, the fair value of liabilities should include consideration of non-performance risk, including the Company’s own credit risk.

The Company applied FASB Accounting Standards Codification (“ASC”) 820 — Fair Value Measurement, which provides guidance for using fair value to measure assets and liabilities by defining fair value and establishing the framework for measuring fair value. ASC 820 applies to financial and nonfinancial instruments that are measured and reported on a fair value basis. The three-level hierarchy of fair value measurements is based on whether the inputs to those measurements are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. The fair value hierarchy requires the use of observable market data when available and consists of the following levels:

● Level 1—Unadjusted inputs based on quoted markets for identical assets or liabilities.

● Level 2—Observable inputs, either direct or indirect, not including Level 1 measurements, corroborated by market data or based upon quoted prices in non-active markets.

● Level 3—Unobservable inputs that reflect management’s best assumptions of what market participants would use in valuing the asset or liability.

The Company has included a tabular disclosure for financial assets and liabilities that are measured at fair value on a recurring basis in the condensed consolidated balance sheets as of September 30, 2023 and December 31, 2022, respectively.

Assets and Liabilities Measured at Fair Value on a Recurring Basis

(1) These amounts are reflected within financial investments in the condensed consolidated balance sheets.

(2) These amounts are reflected within other non-current liabilities in the condensed consolidated balance sheets.

The following is a description of the Company’s valuation methodologies used for instruments measured at fair value on a recurring basis:

Financial Investments

Financial investments consist of highly liquid U.S. Treasury securities, and marketable securities held in a trust for the Company’s non-qualified retirement and benefit plans, also referred to as deferred compensation plan assets. The deferred compensation plan assets have an equal and offsetting deferred compensation plan liability based on the value of the deferred compensation plan assets. These securities are valued by obtaining feeds from a number of live data sources, including active market makers and inter dealer brokers and therefore categorized as Level 1. No material adjustments were made to the carrying value of financial investments for the period ended September 30, 2023. See Note 15 (“Employee Benefit Plans”) for more information.

Digital Assets – Safeguarded Assets and Liabilities

Digital assets – safeguarded assets and liabilities consist of Bitcoin, Ethereum, Litecoin, Bitcoin Cash, and USD Coin. The Company has determined the principal marketplace for digital assets to be the spot market of Cboe Digital Exchange, LLC (“Cboe Digital Exchange”). The Company valued digital assets – safeguarded assets, and digital assets – safeguarded liabilities by using the closing prices at 4:00pm Central Time on Cboe Digital Exchange’s spot market (“Cboe Digital spot market”) as of September 30, 2023. These inputs are categorized in the fair value hierarchy as Level 1 as the marketplace is considered active. See Note 12 (“Clearing Operations”) for additional details regarding digital assets held.

Contingent Consideration Liabilities

In connection with the acquisitions of Hanweck Associates, LLC (“Hanweck”), Cboe Asia Pacific, and Cboe Canada, the Company entered into contingent consideration arrangements with the sellers. The total fair value of the liabilities at September 30, 2023 was $28.2 million. That value is based on the Company’s estimate of the likelihood that certain performance targets in the respective acquisition agreements are expected to be accomplished. In connection with the contingent consideration arrangements, the Company paid a total of $10.9 million in contingent consideration to the sellers of Hanweck, Cboe Asia Pacific and Cboe Canada during the nine months ended September 30, 2023. Because the fair value measurements relating to the contingent consideration liabilities are subject to management judgment, measurement uncertainty is inherent in the valuation of the contingent consideration liabilities as of the reporting date. Based on the recorded balance of the liabilities, any measurement uncertainty related to this Level 3 measurement is immaterial as of September 30, 2023.

Cboe Digital Syndication Liabilities

On November 18, 2022, Cboe Digital Holdings Inc. (“Cboe Digital Holdings”) entered into minority interest purchase agreements with certain digital asset industry participants, pursuant to which Cboe Digital Holdings agreed to issue Restricted Common Units in Cboe Digital. Cboe Digital Holdings also entered into a Warrant Agreement to issue Common Units of Cboe Digital in the future. Certain Cboe Digital investor members paid for the Restricted Common Units through the issuance of promissory notes, which are nonrecourse in nature and are accounted for as in-substance stock options. The cost associated with the Restricted Common Units is recognized as contra-revenue ratably over a five-year period. The Company uses a Black Scholes option pricing model to estimate the fair value of the in-substance stock option created by the Restricted Common Units and promissory notes as well as the fair value of the Warrant. Contra-revenue will be recognized while the performance conditions of the Warrant remain probable in conformance with the requirements in ASC 606 – Revenue from Contracts with Customers. Further adjustments will be recognized in each reporting period until performance is complete relating to changes in the fair value of the option and Warrant liabilities in accordance with ASC 718 – Compensation – Stock Compensation. Based on the recorded balance of the liabilities, any measurement uncertainty related to this Level 3 measurement is immaterial as of September 30, 2023. See Note 17 (“Stock-Based Compensation”) for more information.

Certain Cboe Digital investor members can earn additional Restricted Common Units if they meet certain performance-based metrics outlined in an equity incentive program (“Incentive Program Units”). The Incentive Program Units are subject to the same terms and conditions as the other Restricted Common Units and are similarly liability-classified awards. Cboe Digital authorized a maximum of 20 Common Units to be distributed over the two-year life of the incentive program. The cost associated with the Incentive Program Units will be recognized as contra-revenue ratably over the remaining service period associated with the Incentive Program Units. Further adjustments will be recognized in each reporting period until performance is complete relating to changes in the fair value of the incentive program liabilities in accordance with ASC 718 – Compensation – Stock Compensation. Based on the recorded balance of the liabilities, any measurement uncertainty related to this Level 3 measurement is immaterial as of September 30, 2023. See Note 17 (“Stock-Based Compensation”) for more information.

Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain assets, such as goodwill and intangible assets, are measured at fair value on a non-recurring basis. For goodwill, the process involves using a market approach and income approach (using discounted estimated cash flows) to determine the fair value of each reporting unit on a stand-alone basis. That fair value is compared to the carrying value of the reporting unit, including its recorded goodwill. In connection with the annual impairment evaluation of goodwill and indefinite lived intangibles, impairment is considered to have occurred if the fair value of the reporting unit is lower than the carrying value of the reporting unit. See “Digital Assets Held” below and Note 1 (“Organization and Basis of Presentation”) for discussion of valuation considerations specific to digital assets held. For the other intangible assets, the process also involves using a discounted cash flow method to determine the fair value of each intangible asset.

Impairment is considered to have occurred if the fair value of the intangible asset is lower than its carrying value. These measurements are considered Level 3 and these assets are recognized at fair value if they are deemed to be impaired. In addition, property held for sale as of September 30, 2023 was also measured at fair value at September 30, 2023. See Note 5 (“Property and Equipment, Net”) for more information on property held for sale.

The Company performed impairment testing during the quarter ended June 30, 2022, as there were market events that indicated it was more likely than not that Cboe Digital’s assets were impaired, resulting in the recognition of an impairment charge to goodwill related to Cboe Digital. Subsequently, the Company concluded that the indicators of impairment observed during the quarter ended June 30, 2022, continued to be relevant and recorded additional goodwill impairment in the condensed consolidated statements of income for the three months ended September 30, 2022. The Company determined there were no further impairment indicators for the period ended September 30, 2023. See Note 8 (“Goodwill, Intangible Assets, Net, and Digital Assets Held”) for more information on the impairment.

Equity investments without readily determinable fair values that are valued using the measurement alternative are measured at fair value on a non-recurring basis. No observable transactions or impairments impacted the measurements of the investments accounted for as other equity investments. See Note 4 (“Investments”) for more information.

(1) These amounts are reflected within financial investments in the condensed consolidated balance sheets.

(2) These amounts are reflected within intangible assets, net in the condensed consolidated balance sheets.

(3) These amounts are reflected within other non-current liabilities in the condensed consolidated balance sheets.

Certain financial assets and liabilities, including cash and cash equivalents, accounts receivable, income tax receivable, accounts payable and Section 31 fees payable, and notes receivable are not measured at fair value on a recurring basis, but the carrying values approximate fair value due to their liquid or short-term nature.

Debt

The debt balance consists of fixed rate Senior Notes and a floating rate Term Loan Agreement. The fair values of the Senior Notes are classified as Level 2 under the fair value hierarchy and are estimated using prevailing market quotes. The fair value of the Term Loan Agreement was determined by utilizing a discounted cash flow analysis and is considered a Level 2 measurement.

At September 30, 2023 and December 31, 2022, the fair values of the Company’s debt obligations were as follows (in millions):

	Fair Value
	September 30, 2023		December 31, 2022
Term Loan Agreement	$	71.8	$	306.3
3.650% Senior Notes		615.3		623.6
1.625% Senior Notes		380.3		390.7
3.000% Senior Notes		244.1		253.3

Digital Assets Held

Digital assets held, which are included within intangible assets, net in the condensed consolidated balance sheets, are valued following a review of exchange prices for each specific digital asset throughout the period ended September 30, 2023. The Company will impair to the lowest observable value during the period for each digital asset type in accordance with Cboe Digital’s policy, which states that the Company values digital assets held by using the closing prices at 4:00pm Central Time on Cboe Digital Exchange’s spot market, which the Company determined is the principal marketplace for digital assets. As part of Cboe Digital’s pricing policy, the closing price on Cboe Digital’s spot market is compared to three other exchanges (Coinbase, Bitstamp, and Kraken) and the CoinDesk Price Index to assess for reasonableness. These inputs are categorized in the fair value hierarchy as Level 1 as the marketplace is considered active.

SEGMENT REPORTING

14.  SEGMENT REPORTING

The Company operates six reportable business segments: Options, North American Equities, Europe and Asia Pacific, Futures, Global FX, and Digital which is reflective of how the Company's chief operating decision-maker reviews and operates the business, as discussed in Note 1 (“Organization and Basis of Presentation”). Segment performance is primarily evaluated based on operating income (loss). The Company’s chief operating decision-maker does not use segment-level assets or income and expenses below operating income (loss) as key performance metrics; therefore, such information is not presented below. The Company has aggregated all of its corporate costs, as well as other business ventures, within the Corporate Items and Eliminations totals based on the decision that those activities should not be used to evaluate the operating performance of the segments; however, operating expenses that relate to activities of a specific segment have been allocated to that segment. 

Options. The Options segment includes options on market indices (“index options”), as well as on the stocks of individual corporations (“equity options”), and options on ETPs, such as exchange-traded funds (“ETFs”) and exchange-traded notes (“ETNs”), which are “multi-listed” options and listed on a non-exclusive basis. These options are eligible to trade, as applicable, on Cboe Options, C2, BZX, EDGX, and/or other U.S. national security exchanges. Cboe Options is the Company’s primary options market and offers trading in listed options through a single system that integrates electronic trading and traditional open outcry trading on the Cboe Options trading floor in Chicago. C2 Options, BZX Options, and EDGX Options are all-electronic options exchanges, and typically operate with different market models and fee structures than Cboe Options. The Options segment also includes applicable market data fees generated from the consolidated tape plans, the licensing of proprietary options market data, index licensing, and access and capacity services.

North American Equities. The North American Equities segment includes listed U.S. equities and ETP transaction services that occur on fully electronic exchanges owned and operated by BZX, BYX, EDGX, and EDGA, equities transactions that occur on the BIDS Trading platform, and Canadian equities and other transaction services that occur on or through the MATCHNow ATS and Cboe Canada. The North American Equities segment also includes listing services on Cboe Canada Exchange, ETP listings on BZX, the Cboe Global Markets, Inc. common stock listing, applicable market

data fees generated from the consolidated tape plans, the licensing of proprietary equities market data, routing services, and access and capacity services.

Europe and Asia Pacific. The Europe and Asia Pacific segment includes the pan-European listed equities and derivatives transaction services, ETPs, exchange-traded commodities, and international depository receipts that are hosted on MTFs operated by Cboe Europe Equities (Cboe Europe and Cboe NL equities exchanges) and Cboe Europe Derivatives (“CEDX”). It also includes the ETP listings business on RMs and clearing activities of Cboe Clear Europe, as well as the equities transaction services of Cboe Australia and Cboe Japan, operators of trading venues in Australia and Japan, respectively. Cboe Europe operates lit and dark books, a periodic auctions book, and Cboe BIDS Europe, a Large-in-Scale (“LIS”) trading negotiation facility for UK symbols. Cboe NL, launched in October 2019 and based in Amsterdam, operates similar business functionality to that offered by Cboe Europe, and provides for trading only in European Economic Area (“EEA”) symbols. Cboe Europe Derivatives, a pan-European derivatives platform launched in September 2021, offers futures and options based on Cboe Europe equity indices. This segment also includes Cboe Europe, Cboe NL, CEDX, Cboe Australia and Cboe Japan revenue generated from the licensing of proprietary market data and from access and capacity services.

STOCK-BASED COMPENSATION

9 Months Ended

STOCK-BASED COMPENSATION

STOCK-BASED COMPENSATION

17.  STOCK-BASED COMPENSATION

Stock-based compensation is based on the fair value of the award on the date of grant, which is recognized over the related service period, net of actual forfeitures. The service period is the period over which the related service is performed, which is generally the same as the vesting period. Vesting may be accelerated for certain officers and employees as a result of attaining certain age and service based requirements in the Company’s long-term incentive plan and award agreements.

Stock-based compensation expense relating to employee awards is included in compensation and benefits and acquisition-related costs in the condensed consolidated statements of income. The Company recognized stock-based compensation expense related to employee awards of $1.5 million and $7.0 million for the three months ended September 30, 2023 and 2022, respectively and $28.4 million and $23.1 million for the nine months ended September 30, 2023 and 2022, respectively. Stock-based compensation expense relating to director awards is included in professional fees and outside services in the condensed consolidated statements of income. The Company recognized stock-based compensation expense related to director awards of $0.5 million for each of the three months ended September 30, 2023 and 2022, respectively and $1.4 million for each of the nine months ended September 30, 2023 and 2022, respectively. Stock-based compensation expense relating to awards granted to investor members of Cboe Digital are recorded as contra-revenue in the condensed consolidated statements of income and is outlined further below.

The activity in the Company’s restricted stock, consisting of restricted stock awards (“RSAs”), restricted stock units (“RSUs”), and performance-based restricted stock units (“PSUs”) for the nine months ended September 30, 2023 was as follows:

RSAs and RSUs

The following table summarizes RSA and RSU activity during the nine months ended September 30, 2023:

		Weighted
	Number of	average grant
	Shares	date fair value
Nonvested stock at December 31, 2022	556,062	$	112.07
Granted	338,794		126.50
Vested	(236,487)		108.21
Forfeited	(41,822)		120.51
Nonvested stock at September 30, 2023	616,547	$	120.91

RSUs entitle the holder to one share of common stock upon vesting with the exception of certain jurisdictions where the RSUs are settled in cash, typically vest over a three-year period, and vesting accelerates upon death, disability, or the occurrence of a qualified termination following a change in control. Vesting will also accelerate upon a qualified retirement

where applicable and permitted. Where applicable and permitted, qualified retirement eligibility occurs once achieving 55 years of age and 10 years of service. Unvested RSUs will be forfeited if the officer, or employee leaves the Company prior to the applicable vesting date, except in limited circumstances.

RSUs granted to non-employee members of the Board of Directors have a one-year vesting period and vesting accelerates upon the occurrence of a change in control of the Company. Unvested portions of the RSUs will be forfeited if the director leaves the Board of Directors prior to the applicable vesting date.

The RSUs have no voting rights but entitle the holder to receive dividend equivalents.

There were no remaining nonvested RSAs as of September 30, 2023.

During the nine months ended September 30, 2023, to satisfy employees’ tax obligations upon the vesting of restricted stock, the Company purchased 84,706 shares of common stock totaling $11.1 million as the result of the vesting of 218,699 shares of restricted stock.

PSUs

The following table summarizes restricted stock units contingent upon achievement of performance conditions, also known as PSUs, activity during the nine months ended September 30, 2023:

		Weighted
	Number of	average grant
	Shares	date fair value
Nonvested stock at December 31, 2022	166,702	$	125.08
Granted	86,646		143.75
Vested	(55,399)		130.05
Forfeited	(55,627)		143.52
Nonvested stock at September 30, 2023	142,322	$	127.31

PSUs include awards related to earnings per share during the performance period as well as awards related to total shareholder return during the performance period. The Company used the Monte Carlo valuation model method to estimate the fair value of the total shareholder return PSUs which incorporated the following assumptions for awards granted in February 2023: risk-free interest rate (4.10)%, three-year volatility (33.5)% and three-year correlation with S&P 500 Index (0.53). Each of these performance shares has a performance condition under which the number of units ultimately awarded will vary from 0% to 200% of the original grant, with each unit representing the contingent right to receive one share of the Company’s common stock. The vesting period for the PSUs contingent on the achievement of performance conditions is three years. For each of the performance awards, the PSUs will be settled in shares of the Company’s common stock following vesting of the PSU assuming that the participant has been continuously employed during the vesting period, subject to acceleration upon death, disability, or the occurrence of a qualified termination following a change in control. Participants have no voting rights with respect to the PSUs until the issuance of the shares of common stock. Dividends are accrued by the Company and will be paid once the PSUs, contingent on the achievement of performance conditions, vest.

In the nine months ended September 30, 2023, to satisfy employees’ tax obligations upon the vesting of performance stock, the Company purchased 21,459 shares of common stock totaling $2.7 million as the result of the vesting of 55,399 shares of performance stock.

As of September 30, 2023, there were $50.4 million in total unrecognized compensation costs related to restricted stock, restricted stock units, and performance stock units. These costs are expected to be recognized over a weighted average period of 1.9 years. Forfeited PSUs include certain awards forfeited by Edward T. Tilly, former Chief Executive Officer of the Company, who resigned and voluntarily terminated his employment with the Company on September 18, 2023.

Employee Stock Purchase Plan

In May 2018, the Company’s stockholders approved an Employee Stock Purchase Plan, (“ESPP”), under which a total of 750,000 shares of the Company’s common stock will be made available for purchase to employees. The ESPP is

a broad-based plan that permits employees to contribute up to 10% of wages and base salary to purchase shares of the Company’s common stock at a discount, subject to applicable annual Internal Revenue Service limitations. Under the ESPP, a participant may not purchase more than a maximum of 312 shares of the Company’s common stock during any single offering period. No participant may accrue options to purchase shares of the Company’s common stock at a rate that exceeds $25,000 in fair market value of the Company’s common stock (determined at the time such options are granted) for each calendar year in which such rights are outstanding at any time. The exercise price per share of common stock shall be 85% (for eligible U.S. and international employees) of the lesser of the fair value of the stock on the first day of the applicable offering period or the applicable exercise date.

The Company records compensation expense over the offering period related to the discount that is given to employees, which totaled $0.9 million and $0.2 million for the three months ended September 30, 2023 and 2022, respectively, and $1.8 million and $0.4 million for the nine months ended September 30, 2023 and 2022, respectively. As of September 30, 2023, 552,734 shares were reserved for future issuance under the ESPP.

Cboe Digital Restricted Common Units

On November 18, 2022, Cboe Digital Holdings entered into minority interest purchase agreements with certain digital asset industry participants, pursuant to which Cboe Digital Holdings agreed to issue 185 Restricted Common Units in Cboe Digital. In addition, certain investor members and their affiliates are our customers, including trading permit holders, trading privilege holders, participants, and members. Certain Cboe Digital investor members paid for the Restricted Common Units through the issuance of promissory notes, which are nonrecourse in nature. The issuances of Restricted Common Units for nonrecourse promissory notes are accounted for as in-substance stock options. The promissory notes generally bear interest at a rate of 5% per annum and mature upon the earlier of the sale of vested Restricted Common Units, or either November 18, 2032 or November 18, 2037. One Cboe Digital investor member paid for the Restricted Common Units in exchange for cash.

The following table summarizes the option activity during the nine months ended September 30, 2023 (in millions, except number of units and contractual term):

		Weighted				Weighted
	Number of	average exercise		Aggregate		average remaining
	Units	price		intrinsic value		contractual term
Nonvested units at December 31, 2022	185	$	0.3	$	—	6 years
Granted	—		—		—
Vested	—		—		—
Outstanding at September 30, 2023	185	$	0.3	$	—	5 years

Vesting of Restricted Common Units is based on certain conditions relating to the participation and performance of the Cboe Digital investor members on the Cboe Digital platforms, generally over a five-year period. Performance is generally measured based on participation on the Cboe Digital platforms and the investor members maintaining certain average daily volumes on the platforms. Due to the existence of an option for investor members to sell their shares immediately after vesting, the options are liability classified. The options expire upon the maturity of the promissory notes, which is either November 18, 2032 or November 18, 2037, unless the options are exercised.

The cost associated with the options will be recognized as contra-revenue, net of actual forfeitures and based on the continued probability of the satisfaction of performance conditions ratably over the vesting period. At December 31, 2022, $14.0 million of contra-revenue related to the options grants was included in other assets, net within the condensed consolidated balance sheets. At March 31, 2023 the contra-revenue balance included in other assets, net within the condensed consolidated balance sheet included a $0.1 million adjustment to the Restricted Common Units contra-revenue asset as a result of the finalization of the initial grant date fair value calculation. For the three and nine months ended September 30, 2023, $0.7 million and $2.3 million of contra-revenue related to the options grants was recognized, respectively. As of September 30, 2023, $11.8 million of contra-revenue related to the options grants was included in other assets, net on the condensed consolidated balance sheet, and is expected to be recognized as contra-revenue in the condensed consolidated statements of income over the remaining contractual term.

Changes in the fair value of the options, subsequent to the grant date, is recognized in other income (expense), net in the condensed consolidated statements of income in the period in which the fair value of the options changes. The Company uses a Black Scholes pricing model to estimate the fair value of the in-substance stock options which incorporated the following assumptions as of June 30, 2023: risk-free interest rate range (3.67 to 3.78)%, expected

dividend rate (0)%, expected volatility (60-65)%, and expected term of 4.5 to 6.5 years. For the nine months ended September 30, 2023, there was no change in the fair value of the options grants since the grant date.

​Certain Cboe Digital investor members can earn additional Incentive Program Units. The Incentive Program Units are subject to the same terms and conditions as the other Restricted Common Units and are similarly liability-classified awards. Cboe Digital authorized a maximum of 20 Common Units to be distributed over the two-year life of the incentive program. For the three and nine months ended September 30, 2023, $0.5 million of contra-revenue related to the Incentive Program Units was recognized. As of September 30, 2023, $2.6 million of contra-revenue related to the Incentive Program Units is included in other assets, net within the condensed consolidated balance sheet and is expected to be recognized as contra-revenue in the condensed consolidated statements of income over the remaining service period associated with the Incentive Program Units.

Cboe Digital Warrants

On November 18, 2022, Cboe Digital Holdings entered into a Warrant Agreement with an investor member to acquire up to 80 Common Units of Cboe Digital, subject to certain vesting events. The investor member is a customer of Cboe Digital. The vesting of the Warrant is based upon the achievement of certain conditions relating to the service provided by the investor member over a two-year period, of which some conditions represent conditions that are not service, performance, or market conditions and, therefore, the Warrant is liability classified. As of September 30, 2023, no portion of the Warrant has vested.

The cost associated with the Warrant will be recognized as contra-revenue ratably throughout the expected life of the Warrant before exercise. For the three and nine months ended September 30, 2023, $0.3 million and $0.9 million of contra-revenue related to the Warrant was recognized, respectively. As of September 30, 2023, $5.0 million of contra-revenue related to the Warrant is included in other assets, net within the condensed consolidated balance sheet and is expected to be recognized as contra-revenue in the condensed consolidated statements of income over the remaining life of the Warrant.

The following table summarizes the Warrant activity during the nine months ended September 30, 2023 (in millions, except number of units):

		Weighted
	Number of	average exercise
	Units	price
Nonvested units at December 31, 2022	80	$	0.2
Granted	—		—
Vested	—		—
Outstanding at September 30, 2023	80	$	0.2

Changes in the fair value of the Warrant, subsequent to the grant date, is recognized in other income (expense), net in the condensed consolidated statements of income in the period in which the fair value of the Warrant changes. The Company uses a Black Scholes pricing model to estimate the fair value of the Warrant which incorporated the following assumptions as of June 30, 2023: risk-free interest rate (3.77)%, expected dividend rate (0)%, expected volatility (65)%, and expected term of 4.6 years. For the nine months ended September 30, 2023, there was no change in the fair value of the Warrant since the grant date.

The Company’s common stock is listed on Cboe BZX under the trading symbol CBOE. As of September 30, 2023, 325,000,000 shares of the Company’s common stock were authorized, $0.01 par value, and 108,009,417 and 105,555,989 shares were issued and outstanding, respectively. As of December 31, 2022, 325,000,000 shares of the Company’s common stock were authorized, $0.01 par value, and 107,670,248 and 105,951,199 shares were issued and outstanding, respectively. The holders of common stock are entitled to one vote per share.

Common Stock in Treasury, at Cost

The Company accounts for the purchase of treasury stock under the cost method with the shares of stock repurchased reflected as a reduction to Cboe stockholders’ equity and included in common stock in treasury, at cost in the condensed consolidated balance sheets. Shares repurchased under the Company’s share repurchase program are retired or they are available to be redistributed. When treasury shares are redistributed, they are recorded at the average cost of the treasury shares acquired. When treasury shares are retired, they are removed from the common stock in treasury balance. The Company held 2,453,428 and 1,719,049 shares of common stock in treasury as of September 30, 2023 and December 31, 2022, respectively.

Share Repurchase Program

In 2011, the Board of Directors approved an initial authorization for the Company to repurchase shares of its outstanding common stock of $100 million and subsequently approved additional authorizations for a total authorization of $1.6 billion. The Company expects to fund repurchases primarily through the use of existing cash balances. The program permits the Company to purchase shares, through a variety of methods, including in the open market or through privately negotiated transactions, in accordance with applicable securities laws. It does not obligate the Company to make any repurchases at any specific time or situation.

On August 16, 2022, President Biden signed into law H.R. 5376 (commonly known as the Inflation Reduction Act of 2022 or simply the “IRA”). Tax measures contained in the IRA include, among other items, a new excise tax of 1% on repurchases of stock by domestic corporations with stock traded on established securities markets. The amount on which the tax is imposed is reduced by the value of any stock issued by such corporation during the tax year and the tax generally applies to stock buy-back transactions occurring after December 31, 2022. This new tax is not expected to result in a material impact to the Company.

The Company did not repurchase shares under the Company’s share repurchase program during the three months ended September 30, 2023 and 2022, respectively. Since inception of the program through September 30, 2023, the Company has repurchased 19,576,581 shares of common stock at an average cost per share of $72.03, totaling $1.4 billion.

As of September 30, 2023 and 2022, the Company had $139.8 million and $233.3 million of availability remaining under its existing share repurchase authorizations, respectively.

Purchase of Common Stock from Employees

The Company purchased 5,376 and 1,260 shares that were not part of the publicly announced share repurchase authorization from employees for an average price paid per share of $147.06 and $120.82 during the three months ended September 30, 2023, and 2022, respectively. These shares consisted of shares retained to cover payroll withholding taxes or option costs in connection with the vesting of restricted stock awards, restricted stock units, and performance share awards.

Preferred Stock

The Company has authorized the issuance of 20,000,000 shares of preferred stock, par value $0.01 per share, issuable from time to time in one or more series. As of September 30, 2023, and December 31, 2022, the Company had no shares of preferred stock issued or outstanding.

Dividends

During the three months ended September 30, 2023, the Company declared and paid cash dividends per share of $0.55 for an aggregate payout of $58.5 million. During the three months ended September 30, 2022, the Company declared and paid cash dividends per share of $0.50 for an aggregate payout of $53.4 million.

Each share of common stock, including RSUs and PSUs, is entitled to receive dividend and dividend equivalents, respectively, if, as and when declared by the Board of Directors of the Company. The Company’s expectation is to continue to pay dividends. The decision to pay a dividend, however, remains within the discretion of the Company’s Board of Directors and may be affected by various factors, including earnings, financial condition, capital requirements, level of

indebtedness and other considerations the Board of Directors deems relevant. Future debt obligations and statutory provisions, among other things, may limit, or in some cases prohibit, the Company’s ability to pay dividends.

As a holding company, the Company’s ability to declare and continue to pay dividends in the future with respect to its common stock will also be dependent upon the ability of its subsidiaries to pay dividends to it under applicable corporate law.

INCOME TAXES

19.  INCOME TAXES

The Company records income tax expense during interim periods based on the best estimate of the full year’s tax rate as adjusted for discrete items, if any, that are taken into account in the relevant interim period. Each quarter, the Company updates its estimate of the annual effective tax rate and any change in the estimated rate is recorded on a cumulative basis. The effective tax rate from continuing operations was 22.9% and 34.4% for the three months ended September 30, 2023 and 2022, respectively, and 27.7% and 61.8% for the nine months ended September 30, 2023 and 2022, respectively.

The effective tax rate for the three months ended September 30, 2023 is lower than it was for the same period in 2022 primarily as a result of the release of income tax reserves associated with penalties and interest thereon as a result of the remeasurement of tax reserves related to Section 199 deduction claims which were in dispute with the Internal Revenue Service (“IRS”). The Company has reached a settlement with the IRS under which the Company has conceded all the claimed Section 199 deductions in exchange for the IRS’s concession of penalties asserted on the Company’s Section 199 deductions. Although the parties had not completed all legal procedures to affect the settlement at September 30, 2023, the IRS provided a written response agreeing to these terms prior to September 30, 2023. The Company accordingly remeasured its Section 199 tax reserve liabilities and released its reserves associated with penalties and interest thereon for its Section 199 claims as of September 30, 2023. Subsequent to September 30, 2023, the parties have completed all legal procedures to affect the settlement.

The lower effective tax rate for the nine months ended September 30, 2023 compared to the same period in 2022 is primarily due to the circumstances outlined above, coupled with lower income before income tax provision for the nine months ended September 30, 2022 as a result of the Cboe Digital goodwill impairment.

EARNINGS PER SHARE

EARNINGS PER SHARE

20.  EARNINGS PER SHARE

The computation of basic net income per common share is calculated by reducing net income for the period by dividends paid or declared and undistributed net income for the period that are allocated to participating securities to arrive at net income allocated to common stockholders. Net income allocated to common stockholders is divided by the weighted average number of common shares outstanding during the period to determine net income per share allocated to common stockholders.

The computation of diluted net income per share is calculated by dividing net income allocated to common stockholders by the sum of the weighted average number of common shares outstanding plus all additional common shares that would have been outstanding if the potentially dilutive common shares had been issued. The dilutive effect is calculated using the more dilutive of the two-class or treasury stock method.

The following table sets forth the computation of basic and diluted earnings per share for the three and nine months ended September 30, 2023 and 2022 (in millions, except per share data):

	Three Months Ended September 30,				Nine Months Ended September 30,
	2023		2022		2023		2022
Basic earnings per share numerator:
Net income	$	208.2	$	150.2	$	549.4	$	75.3
Net income allocated to participating securities		(1.1)		(0.6)		(2.7)		(0.6)
Net income allocated to common stockholders	$	207.1	$	149.6	$	546.7	$	74.7
Basic earnings per share denominator:
Weighted average shares outstanding		105.7		106.2		105.8		106.4
Basic earnings per share	$	1.96	$	1.41	$	5.17	$	0.70
Diluted earnings per share numerator:
Net income	$	208.2	$	150.2	$	549.4	$	75.3
Net income allocated to participating securities		(1.1)		(0.6)		(2.7)		(0.6)
Net income allocated to common stockholders	$	207.1	$	149.6	$	546.7	$	74.7

Diluted earnings per share	$	1.95	$	1.41	$	5.15	$	0.70

For the periods presented, the Company did not have shares of stock-based compensation that would have an anti-dilutive effect on the computation of diluted earnings per share.

Legal Proceedings

As of September 30, 2023, the Company was subject to various legal proceedings and claims that have not been fully resolved and that have arisen in the ordinary course of business.

The Company reviews its legal proceedings and claims, regulatory reviews and inspections and other legal proceedings on an ongoing basis and follows appropriate accounting guidance when making accrual and disclosure decisions. The Company establishes accruals for those contingencies where the incurrence of a loss is probable and can be reasonably estimated, and the Company discloses the amount accrued and the amount of a reasonably possible loss in excess of the amount accrued, if such disclosure is necessary for the condensed consolidated financial statements to not be misleading. The Company does not record liabilities when the likelihood that the liability has been incurred is probable, but the amount cannot be reasonably estimated, or when the liability is believed to be only reasonably possible or remote. The Company’s assessment of whether a loss is remote, reasonably possible, or probable is based on its assessment of the ultimate outcome of the matter following all appeals.

As of September 30, 2023, the Company does not believe that there is a reasonable possibility that any material loss exceeding the amounts already recognized for these legal proceedings and claims, regulatory reviews, inspections or other legal proceedings, if any, has been incurred. While the consequences of certain unresolved proceedings are not presently determinable, the outcome of any proceeding is inherently uncertain and an adverse outcome from certain matters could have a material effect on the financial position, results of operations, or cash flows of the Company in any given reporting period.

Other

As self-regulatory organizations under the jurisdiction of the SEC, Cboe Options, C2, BZX, BYX, EDGX and EDGA are subject to routine reviews and inspections by the SEC. As a designated contract market under the jurisdiction of the CFTC, CFE, and Cboe Digital Exchange are subject to routine rule enforcement reviews and examinations by the CFTC. As a derivatives clearing organization under the jurisdiction of the CFTC, Cboe Clear Digital is also subject to routine audits and examinations by state regulators. Cboe SEF, LLC is a swap execution facility registered with the CFTC and subject to routine rule enforcement reviews and examinations by the CFTC. Cboe Trading, BIDS Trading and Cboe Fixed

Income are subject to reviews and inspections by FINRA. The Company has from time to time received inquiries and investigative requests from the SEC’s Division of Examinations and the CFTC’s Division of Market Oversight as well as the SEC Division of Enforcement and CFTC Division of Enforcement seeking information about the Company’s compliance with its obligations as a self-regulatory organization under the federal securities laws and Commodity Exchange Act as well as members’ compliance with the federal securities laws and Commodity Exchange Act.

In addition, while Cboe Europe, Cboe Chi-X Europe, Cboe Clear Europe, Cboe NL, Cboe Australia, Cboe Japan, MATCHNow, and Cboe Canada have not been the subject of any litigation or regulatory investigation in the past that resulted in a material impact on the Company’s financial position, results of operations, liquidity or capital resources, there is always the possibility of such action in the future. As Cboe Europe and Cboe Chi-X Europe are domiciled in the UK, it is likely that any action would be taken in the UK courts in relation to litigation or by the FCA in relation to any regulatory enforcement action. As Cboe Clear Europe is domiciled in the Netherlands, it is likely that any action would be taken in the Dutch courts in relation to litigation or by the DNB or Dutch Authority for Financial Markets in relation to any regulatory enforcement action. For Cboe NL, also domiciled in the Netherlands, it is likely that any actions would be taken in the Dutch courts in relation to litigation or Dutch Authority for Financial Markets in relation to any regulatory enforcement action. As Cboe Australia is domiciled in Australia, it is likely that any action would be taken in the Australian courts in relation to litigation or by the ASIC, in relation to any regulatory enforcement action. As Cboe Japan is domiciled in Japan, it is likely that any action would be taken in the Japanese courts in relation to litigation or by the JFSA or the JSDA in relation to any regulatory enforcement action. As MATCHNow and Cboe Canada are domiciled in Canada, it is likely that any action would be taken in the Canadian courts in relation to litigation or by the OSC and/or CIRO in relation to any regulatory enforcement action.

Cboe Digital has committed to securely store all digital assets it holds on behalf of users. As such, Cboe Digital may be liable to its users for losses arising from theft or loss of user private keys. Cboe Digital has no reason to believe it will incur any expense associated with such potential liability because (i) it has no known or historical experience of claims to use as a basis of measurement, (ii) it accounts for and continually verifies the amount of digital assets within its control, and (iii) it has established security around custodial private keys to minimize the risk of theft or loss. There were no loss events impacting safeguarded assets caused by the theft or loss of digital asset user private keys as of September 30, 2023. As such, the Company had not recorded a liability at September 30, 2023.

The Company is also currently a party to various other legal proceedings in addition to those already mentioned. Management does not believe that the likely outcome of any of these other reviews, inspections, investigations or other legal proceedings is expected to have a material impact on the Company’s financial position, results of operations, liquidity or capital resources.

Contractual Obligations

The Company has contractual obligations related to licensing agreements with various licensors, some of which included fixed fees and/or variable fees calculated using agreed upon contracted rates and reported cleared volumes. Certain licensing agreements contain annual minimum fee requirements that total between $15.0 and $16.1 million each year for the next five years. Cboe Canada has purchase obligations primarily related to software development activities of $1.3 million in total over the next three years.
