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, 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.

On September 18, 2023 (the “Effective Date”), Edward T. Tilly, former Chief Executive Officer of the Company, resigned and voluntarily terminated his employment with the Company. 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 (in substitution of his prior role as Lead Director of the Board of Directors).

Competitive Strengths

Cboe is a leading provider of market infrastructure and tradable products across cash and spot markets, derivatives markets, and data and access solutions. Cboe delivers cutting-edge trading, clearing and investment solutions across the globe through a comprehensive ecosystem that helps drive innovation and growth.

Table of Contents

Key Growth Strategy Initiatives

Our strategy is to build one of the world’s largest global derivatives and securities networks to create value and drive growth by:

Proprietary Products

In addition to operating cash and spot markets and derivative markets, and providing data and access solutions, we are a leader in the volatility space with the proprietary products we offer for trading. These proprietary products are built through Cboe Labs, a dedicated team centered on the creation, development, and implementation of new ideas and our strategic relationships and license agreements with index providers, which are both described below in further detail. Our most frequently traded proprietary products include SPX options and VIX options and futures.

SPX Options

The S&P 500 Index is an index comprised of 500 large-cap U.S. listed companies. It is one of the most commonly followed indices and is considered a bellwether for the U.S. economy. The SPX options we offer on the S&P 500 Index are exclusive to Cboe and contribute substantially to our volumes and transaction fees. Because of the S&P 500 Index’s status as a bellwether, SPX options are used in many different trading strategies by customers with different goals, including pension funds hedging their equity exposure by buying put options, asset managers seeking enhanced returns by selling covered call options and hedge funds using risk-managed strategies to capture so-called “risk premia” embedded in option prices. We also offer zero days to expiry (0-DTE) products, Mini- and Nano-SPX options, FLEX- and FLEX micro-SPX options, and SPX Weeklys options, which have settlements on Mondays, Tuesdays, Wednesdays, Thursdays, Fridays and on the last trading day of each month and 24x5 trading in SPX options. We believe these additional expirations provide customers with more precision when hedging overall portfolio risk.

Volatility Trading

Cboe pioneered the trading of exchange-traded volatility products with its introduction of VIX futures in 2004 and VIX options in 2006. The VIX Index (as defined below), although not directly tradable, is based on the mid-point of real-time

Table of Contents

quotes of SPX options and is designed to reflect investors’ consensus view of future 30-day expected stock market volatility. The VIX Index methodology provides the basis for the creation of VIX options and futures. The final settlement value of VIX options and futures is determined on their expiration date through a Special Opening Quotation (“SOQ”) of the VIX Index. The SOQ calculation uses opening trade prices of selected options; unless there is no opening price, in which case the opening price used in the SOQ calculation is the midpoint of the highest bid and lowest offer at the time of the opening. Since we started offering these products, we have seen trading from a number of different customer segments utilizing a number of different trading strategies, including hedging extreme stock market declines, also known as “tail risk” hedging, and risk-managed strategies that seek to capture the relative price changes of expected volatility at different times in the future. We also offer the 1-Day Volatility Index (VIX1D), VIX Weeklys options and futures, mini VIX futures, and 24x5 trading in VIX options and futures to provide investors with additional tools to trade volatility.

Proprietary Indices

We also calculate and disseminate proprietary indices that are licensed for use by third parties or are used as the basis for Cboe proprietary products. These proprietary indices are built both through our in-house research and development staff of the Data and Access Solutions business and our strategic relationships and license agreements with index providers, which are both described below in further detail. Our proprietary indices include:

● volatility indices based on ETFs, and

In addition to any transaction fee revenue generated from trading of products based on these indices on Cboe exchanges, we distribute these indices through the Cboe Global Index Feed index data subscription service and, together with index providers with whom we have strategic relationships, we license proprietary indices for third parties to use to create third-party indices and products. Accordingly, we generate revenue from proprietary indices by distributing them for reference purposes, using them as the basis for proprietary products and licensing them for use for third-party indices and products.

Strategic Index Provider Relationships

The Company has long-term business relationships with several providers of market indices. We license their indices, including on an exclusive basis, as the foundation for indices, index options and other products. The Company also agrees to work jointly with key providers to develop new products and services that are expected to capitalize on our core competencies and diversify our sources of revenue. Of particular note are the following:

Table of Contents

Data and Access Solutions

The Data and Access Solutions business provides an offering of market data and information solutions products across multiple asset classes and geographic regions that are designed to suit our customers’ diverse needs. The Data and Access Solutions business consists of three product groups:

We provide data services to market participants globally through a number of distribution channels including direct, via our vendor partners and Cboe Global Cloud, which is our global cloud data distribution service.

U.S. Tape Plans

We also derive a portion of our revenue from market data fees from U.S. tape plans, including Unlisted Trading Privileges (“UTPs”), the Consolidated Tape Association (“CTA”) and OPRA. Fees, net of plan costs, from UTP, CTA, and OPRA are allocated and distributed to plan participants like us according to their share of tape fees based on a formula, required by Regulation NMS, which may take into account both trading and quoting activity.

Table of Contents

Our Market Models

We operate a variety of derivatives and cash and spot markets. Our markets use a combination of pricing and market models to differentiate them from each other and from our competitors.

For our U.S. derivatives options markets, Cboe Options is a hybrid market combining open outcry floor trading with electronic trading. For multi-listed products, we utilize public customer priority, market turner in certain products, participation rights and pro-rata allocation market models, combined with the “classic” pricing model. Under the classic pricing model, professional participants pay transaction fees, public customers generally do not pay transaction fees and market makers compensate brokers for sending order flow to the exchange (known as payment for order flow). For proprietary products, we use price-time or pro-rata allocation, sometimes with public customer priority, and market turner market models, combined with a pricing model where all market participants generally pay fees. Our other three options markets are fully electronic. BZX options utilizes a price-time market model, combined with a “maker-taker” pricing model. Under the maker-taker pricing model, market participants who make the market (a “maker”) generally receive a rebate, while market participants who trade against those markets (a “taker”) pay a transaction fee. EDGX options utilizes customer priority, participation rights and pro-rata allocation market models, combined with the classic pricing model. C2 options utilizes a pro-rata allocation market model, combined with the maker-taker pricing model.

For CFE’s U.S. derivatives futures market, which is fully electronic, CFE utilizes a price-time market model, combined with a pricing model where all market participants generally pay fees, subject to specified exceptions.

For our U.S. cash and spot markets, the U.S. equities exchanges, which are fully electronic, offer various market models. BZX equities utilizes a price-time market model, combined with the maker-taker pricing model. EDGX equities utilizes a price-time with retail priority market model, combined with the maker-taker pricing model. BYX equities utilizes a price-time with price improvement for retail customers market model, combined with the “taker-maker” pricing model. Under the taker-maker pricing model, market participants who make the market pay a transaction fee, while market participants who trade against those markets receive a rebate. EDGA equities utilizes a price-time market model, combined with a taker-maker pricing model. In addition to these market models, each of the U.S. equity exchanges provides numerous specific order types that are designed to enhance their respective market models.

For our cash and spot markets, BIDS Trading, the U.S. equities ATS market, which is fully electronic and is an independently managed and operated trading venue, separate from and not integrated with the Exchanges, utilizes a sponsored access model to provide anonymous executions in NMS stocks. BIDS Trading provides numerous order types, including both firm and conditional orders. All orders matched within BIDS Trading are executed at or better than the National Best Bid and Offer (“NBBO”). BIDS Trading charges fees based on disclosed, objective criteria: (i) means of access; (ii) the type of order; and (iii) the total volume of executions during the calendar month. Cboe and BIDS Trading collaborate in operating similar venues with our cash and spot markets in Australia, Canada, Europe, and Japan.

In Canada, for our cash and spot markets, Cboe Canada Inc., a recognized Canadian securities exchange, which is fully electronic, offers four order books: NEO-L, which provides resting orders with priority over high-frequency orders and combines a maker-taker pricing model with a NEO trader priority; NEO-N, which prioritizes larger resting orders over smaller orders, imposes a speed bump, and displays volume aggregate by price, with a taker-maker pricing model; NEO-D, which allows participants to submit marketable and resting orders with specified parameters and NEO trader priority with size-time priority, with a taker-maker pricing model; and MATCHNow, which combines frequent call matches and continuous execution opportunities in a confidential trading book, using real-time quotes for protected transparent Canadian markets, accepting both firm and conditional orders, and matching firm orders at three levels of price improvement. Trading fees are typically calculated as a function of trade volume and share price.

In Europe, we operate a number of market models, including continuous Lit orderbooks, periodic auction orderbooks, dark midpoint orderbooks, a post-closing cross, as well as BIDS Europe. Fees are typically charged on an ad valorem basis based on traded notional value, and are differentiated by orderbook, by order type, by monthly value traded, and in the case of Lit orderbooks by liquidity providing/taking orders where (on a subset of orderbooks) a rebate may be paid to the provider of passive liquidity. Following the implementation of the Directive on Markets in Financial Instruments (Directive 2014/65/EU) (“MiFID II”), for the derivatives and cash and spot markets, rebates are generally available if they are tied to a market making scheme or specific service.

In Australia, for our derivatives and cash and spot markets, Cboe Australia, a regulated stock exchange, which is fully electronic, utilizes a model that charges a different ad valorem fee rate depending on whether a participant is making or

Table of Contents

taking liquidity. Fee waivers are also provided to participants registered as market makers, but payments for order flow are prohibited.

In Japan, for our cash and spot markets, Cboe Japan, offers two fully electronic displayed markets, Cboe-Alpha, which utilizes a price-time market model, combined with the “maker-taker” pricing model and Cboe-Select, which utilizes a price-time retail customers focused market model, combined with the “taker-maker” pricing model. Cboe Japan also offers two fully electronic non-displayed markets, Cboe-Match, which matches volume-weighted average price (“VWAP”) orders during pre-market hours and Cboe BIDS Japan, which utilizes a price-time market model aiming for primary market mid-point trades.

For our FX spot markets, the Cboe FX platform utilizes a price-firmness-time priority market model, combined with a pricing model where users are charged either a flat or tiered commission rate based upon the notional amount traded on the platform. For our FX NDF markets, Cboe SEF utilizes a price-firmness-time priority market model and charge a flat commission based upon the notional amount traded on the platform and the capacity in which a participant is trading. Cboe Digital, which is fully electronic, for our digital asset spot and futures markets, utilizes a price-time priority model.

Our markets also charge fees for the opportunity to trade or access our markets, including fees for trading-related functionality. To facilitate trading, we also charge fees for certain technology services, terminal and other equipment rights, maintenance services, trading floor space and telecommunications services.

Listing

Cboe operates five listing venues across the globe that are structured and designed, in the U.S. and Canada, for all types of equity instruments, such as ETPs, corporate securities, warrants and depositary receipts, while in the UK and EU they support ETPs only. In Australia, both ETPs and warrants are supported. Over the course of 2023, Cboe added approximately 800 listings across the globe and had approximately 2,080 listings for the year ended December 31, 2023. Cboe also launched Cboe Global Listings in June of 2023, the first-of-its-kind, global listing network facilitating worldwide access to capital and secondary liquidity for companies and ETFs, and successfully attracted its first intralisted corporate issuer to the global platform.

Clearing

Our subsidiary Cboe Clear Europe, a European central counterparty (“CCP”), provides post-trade clearing services, to stock exchanges, multilateral trading facilities and for over-the-counter equities trades and exchange-traded derivatives trades. Cboe Clear Europe acts as a central counterparty that, for its clearing participants, becomes the buyer to every seller and the seller to every buyer. As a result, it guarantees the timely performance of the settlement obligations of buyers and sellers and takes on the risk of the performance of the transactions that it clears. Additionally, as a Financial Market Infrastructure, Cboe Clear Europe is subject to strict business continuity requirements and regulatory oversight. In 2023, Cboe Clear Europe provided CCP protection for an average of €44 billion of cleared value on a daily basis. Through the process of netting, in 2023, Cboe Clear Europe eliminated 71%, or €31 billion of the average daily cleared value, leaving an average daily settlement value of €13 billion. In 2022, Cboe Clear Europe provided CCP protection for an average of €48 billion of cleared value on a daily basis. Through the process of netting, in 2022, Cboe Clear Europe eliminated 71%, or €34 billion of the average daily cleared value, leaving an average daily settlement value of €14 billion.

Cboe Clear Digital is a digital asset clearinghouse and central counterparty that provides clearing and settlement of digital asset trades for its affiliate, Cboe Digital Exchange. Cboe Clear Digital clears cryptocurrencies from 50 U.S. jurisdictions authorized by license or not subject to licensing. In 2023, Cboe Clear Digital cleared $18 billion in notional volume. In 2022, for the period subsequent to the acquisition, Cboe Clear Digital cleared $4 billion in notional volume.

Table of Contents

BIDS Trading, which are SEC-registered broker-dealers, and certain customers of those broker-dealers. Our futures customers include banks, futures commission merchants and their customers, hedge funds, asset managers, proprietary trading firms, and Commodity Trading Advisors. Similarly, our equities’ customers in Europe are European Union (“EU”) regulated brokerage and proprietary trading firms, as well as sponsored access clients of these brokerage firms and certain non-EU regulated and unregulated direct access participants. Cboe Clear Europe clears equities, equity like instruments traded on 47 European trading segments. Cboe Clear Europe also clears equity derivative instruments traded on Cboe NL. Cboe Clear Europe clearing participants include EEA regulated banks and brokerage trading firms. Our institutional global FX customers include banks, broker-dealers, hedge funds, asset managers, proprietary trading firms, Commodity Trading Advisors, and corporates. Our digital asset customers in the U.S. include SEC-registered broker-dealers, the customers of those broker-dealers, financial institutions, trading platforms, institutional and individual investors, futures commission merchants, introducing brokers, and professional traders. Access to our markets and trading rights and privileges depend upon the nature of the customer, such as whether the individual or firm is (or is eligible to become) a trading permit holder, trading privilege holder, member, participant, or subscriber of one of our markets.

Competition

The industry in which we operate is intensely competitive. We believe we face competition on a number of factors, including:

● price, quality and speed of our trade and clearing execution;

● functionality and ease of use of our trading and clearing platforms;

● reliability, integrity, range and functionality of our products and services;

● integrity of our marketplaces;

● technological innovation and adaption;

● our brand awareness; and

● our reputation.

We believe that we compete favorably with respect to these factors through a variety of methods, including:

● offering efficient, transparent and liquid marketplaces;

● offering deep and liquid markets with opportunities for price improvement;

● offering broad trading platform access in the EU;

● maintaining close relationships with customers; and

In our proprietary products, we compete against other futures exchanges and swap execution facilities that offer similar products, as well as against financial market participants that offer similar over-the-counter derivatives. We also compete against certain multi-listed options products, such as SPY options and cash settled index options, which may offer similar market exposure of our proprietary products, such as SPX options.

The multi-listed options industry is extremely competitive. We expect this trend to continue. As of December 31, 2023, our four options exchanges compete with 13 other U.S. options exchanges, in large part due to existing exchange holding companies opening new exchanges that offer different markets and pricing models on existing technology. Most of the equity and ETP options listed and traded on our exchanges are also listed and traded on the other exchanges. In addition, the options exchanges that we compete with set fees and rebates to attract multi-listed options business to their exchanges, which has historically reduced the net revenue per contract that we generate from multi-listed options, and the options exchanges that we compete with structure their options businesses in partnership with established market participants, such as consolidators, and other order flow providers, to increase their volume traded.

Our U.S. equities and the BIDS Trading ATS compete against 12 other equities exchanges as of December 31, 2023, and over 25 other ATSs and single dealer platforms. Market participants have multiple venues for the execution of orders, including national securities exchanges and numerous off-exchange venues, including other ATSs and broker-dealers that internalize orders off-exchange. Additionally, corporate and ETP issuers have multiple venues they can choose from in the listing of their products. In Canada, our recognized Canadian securities exchange, Cboe Canada Inc., competes with several Canadian exchanges and ATSs. In Australia, our exchange, Cboe Australia, competes with other Australian exchanges and ATSs. In Japan, our equities exchanges and ATSs, compete with several Japanese exchanges and other ATSs.

The market for execution and clearing services in Europe became more competitive following the introduction of MiFID II and the Regulation on Markets in Financial Instruments (Regulation (EU) No 600/2014) (“MiFIR”). Our major competitors in Europe include national stock exchanges, other pan-European MTFs, systematic internalizers, and other European clearinghouses.

The global FX market remains severely fragmented, with transparent automated marketplaces such as Cboe FX challenging a small number of similarly situated competitors. While the global FX market has experienced a shift from competing interbank platforms to ECNs, the electronification of the spot and NDF FX market may encounter resistance from customers that still prefer to utilize the phone, instant chats, terminals and key banking relationships for price discovery and trading. Furthermore, electronification of the FX market appears to be experiencing more resistance outside the U.S. The electronic spot FX market is also intensely competitive, with over 10 other venues competing for market share as of December 31, 2023. Cboe measures and reports on market share against a narrower set of competitors, included in those venues.

Our digital asset spot market, regulated futures exchange, and regulated clearinghouse, compete against other spot trading platforms, futures exchanges, and decentralized trading platforms that offer similar instruments.

In addition, our data and access solutions face competition from other securities exchanges, technology companies, third-party market data providers, and information and software vendors, which have their own substantial market data distribution capabilities that serve as alternative means for receiving open market data feeds instead of connecting directly to our exchanges or trading venues. The sale of our proprietary data products is also under competitive threat from ATSs and trading venues that offer similar products. Distributors and consumers of our market data may also use our market data as an input into a product that competes against one of our traded or cleared products.

Technology

Cboe Trading Technology

The trading platform for our equities, options, and futures markets is developed, owned, and operated in-house and is designed to optimize reliability, speed, scalability, and versatility. Our exchanges provide different market models, appealing to different user bases, and the trading technologies support all of them. Further, the technologies are designed to support many specialized features for each of the markets, such as: dark pools, trade reporting facility, systematic internalizer, Large-in-Scale, smart order routing, FLEX options, 24x5 trading, and hybrid trading (combining electronic and open outcry). In addition, Cboe and its applicable subsidiaries operate separate trading and/or clearing platforms, as applicable, for BIDS Trading, certain Cboe Canada Inc. order books, Cboe Digital, Cboe Clear Europe, and Global FX.

Our trading platforms have generally experienced very low operational downtime and low latency. The trading platforms use readily available hardware, thereby minimizing capital outlays required for each new market entry. Also, in order to continue to implement new enhancements to our trading platforms, new releases of software are generally deployed routinely in all of the applicable markets.

Disaster Recovery

We operate and maintain geographically diverse disaster recovery facilities for all of our markets. We expect that the disaster recovery facilities can be up and running in a short period of time and in certain instances we work with our market participants to try to quickly reopen marketplaces. We regularly test our data center recovery plans and periodically carry out weekend tests using our back-up data centers, as well as an annual test with our U.S. trading participants. In Canada, as required by local regulations, Cboe Canada Inc. conducts internal testing of its disaster recovery data processing capabilities at least annually, and it participates in the bi-annual testing coordinated by CIRO. Cboe Australia and Cboe Japan conduct internal testing of their disaster recovery data processing capabilities at least annually. In Europe, we also regularly test our data center recovery plans and periodically carry out weekend tests which

use our back-up data center, as well as an annual test with our European trading participants. We continue to work to improve both the availability of our technology and our disaster recovery facilities.

Emerging Technologies

We are exploring the potential use of new technologies, such as artificial intelligence (“AI”), machine learning, blockchain, distributed ledger technology, quantum computing, tokenization, the cloud, and other emerging technologies to potentially help drive new products, increase productivity, improve our self-regulatory oversight responsibilities, and increase automation of tasks.

Routing and Clearing

OCC is the sole provider of clearing on all of our U.S. options exchanges and CFE. National Securities Clearing Corporation (“NSCC”), a subsidiary of the Depository Trust and Clearing Corporation (“DTC”), is the sole provider of clearing on our U.S. listed equity exchanges. The Canadian Depository for Securities (“CDS”) is the sole provider of clearing on all equities transactions occurring on Cboe Canada Inc. With respect to Australian equities and derivatives, Cboe Australia delivers matched trades of its 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. The Japan Securities Clearing Corporation (“JSCC”) is the sole provider of clearing on all equities transactions occurring on Cboe Japan’s Cboe-Alpha, Cboe-Select, Cboe-Match and Cboe BIDS Japan. BofA Securities, Inc. (“BOA”) is the sole provider of clearing on all equities transactions occurring on BIDS Trading. Cboe Europe Equities relies on LCH Limited and LCH SA (“LCH”), Cboe Clear Europe, and SIX x-clear Ltd (“SIX x-clear”) to clear trades in European listed equity securities and exchange traded products as part of an interoperable clearing model. For derivatives, Cboe NL relies on Cboe Clear Europe to clear both index and single stock derivative contracts. Cboe Clear Digital is the sole provider of clearing and settlement of all digital asset transactions occurring on Cboe Digital Exchange.

Cboe Trading is a routing broker-dealer used by our four U.S. equities exchanges and our four U.S. options exchanges, including the electronic platform portion of Cboe Options. Cboe Trading’s clearing firms are Wedbush Securities, Inc. (“Wedbush”) and Morgan Stanley & Co. LLC (“Morgan Stanley”).

Digital Assets and Recent Developments

Cboe Digital is an operator of a U.S. based digital asset spot market, a regulated futures exchange, and a regulated clearinghouse. As described in further detail below, Cboe Digital does not engage in proprietary trading activities and does not maintain a trading entity. Cboe Digital does not itself trade digital assets, does not trade on its own exchange, and does not maintain an affiliate trading entity for purposes of trading, market making, or liquidity provision on its exchange. Cboe Clear Digital maintains its own operating funds in separate bank accounts from its customer funds. Each bank account and digital wallet is appropriately titled in accordance with applicable regulatory requirements thus helping to ensure that customer assets are clearly denoted as such.

Cboe Digital takes several steps to isolate the digital assets held for customers from its own assets and to structure customer accounts in a way that reinforces customer ownership of digital assets. Primarily, Cboe Digital holds customer digital assets separate from its own assets in customer accounts, referred to as wallets, with long-term storage by a third party custody provider and licensed trust company. When Cboe Digital temporarily holds digital asset for customers to enable the inbound receipt and outbound transmittal of virtual currencies, customer digital assets are held in omnibus wallets titled for the benefit of customers of Cboe Digital. Digital assets of customers (but not those of Cboe Digital) are held together in the omnibus wallets, and Cboe Digital maintains the records of the amount and type of digital asset owned by each of its customers in the omnibus wallets. Cboe Digital does not hold its own corporate assets together with the customer digital assets in the omnibus wallets, other than corporate assets that are held in omnibus wallets to facilitate customer transactions relating to the digital assets contained in the omnibus wallet, including in order to pay customary transaction fees and expenses. Because Cboe Digital does not have a trading entity for proprietary or liquidity trading purposes, Cboe Digital maintains its own digital assets only to facilitate customer trading. Cboe Digital does not currently pledge, rehypothecate, or invest customer digital assets, although its customer agreements and rulebook permit it to do so in the future. Additionally, Cboe Digital does not otherwise use customer digital assets for its own corporate or business purposes.

Further, 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

Table of Contents

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.

Also, 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.

Cboe Clear Digital clears cryptocurrencies from 50 U.S. jurisdictions authorized by license or not subject to licensing. Cboe Clear Digital performs a guarantee function whereby Cboe Clear Digital helps to ensure that the obligations of the transactions it clears are fulfilled. Spot trading is either cleared on a fully funded basis or by providing non-material daily trading limits to certain well-qualified institutional clearing members. In order to help mitigate the impact of any potential default by such a clearing member, extension of any trading limits is accompanied by performing credit due diligence, requiring posting of collateral or other forms of financial guarantee and hard pre-trade limits. Cboe Digital does not allow access from unauthorized or impermissible jurisdictions, and has taken active steps to help prevent such access and to help prevent circumvention of our controls. To help 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.

While Cboe Digital and its vendors have experienced cybersecurity threats and events of varying degrees, we are not aware of any of these threats or events having a material impact on Cboe Digital’s business, financial condition or operating results to date. However, there can be no assurance that we or our vendors and custodians will not experience future threats or events that may be material. If any such threats or events materialize, we may be subject to contractual restrictions, liability and damages, loss of business, penalties, unfavorable publicity, and increased scrutiny by regulators, which may have an adverse effect on our business.

The bankruptcy of FTX and the bankruptcies of other digital asset platforms has brought increased scrutiny to the digital asset industry. FTX’s bankruptcy and the bankruptcies of other digital asset platforms did not have a direct material effect on Cboe’s overall business or financial condition in 2023.

Cboe Digital launched trading and clearing in margin futures on Bitcoin and Ether on January 11, 2024. With this launch, Cboe Digital became the first U.S. regulated crypto native exchange and clearinghouse to enable both spot and leveraged derivatives trading on a single platform.

Regulatory Environment and Compliance

Various aspects of our business are subject to regulation by the SEC, CFTC, FINRA, the New York Department of Financial Services (“NYDFS”), various state regulators, CIRO, the Canadian Securities Administrators (and, in particular, the Ontario Securities Commission or “OSC”), the Australian Securities & Investments Commission (“ASIC”), JFSA, JSDA, ESMA, FCA, the Central Bank of the Netherlands (“DNB”), AFM, Bank of England, and other international regulatory authorities where our exchanges or Cboe Clear Europe may be authorized to act as foreign exchanges or provide clearing services, and market participants may be subject to regulation by the SEC, CFTC, FINRA, National Futures Association (“NFA”), FCA, Board of Governors of the Federal Reserve, U.S. Department of the Treasury and/or

foreign regulators. The following is a discussion of the more significant areas of regulation of us by the SEC, the CFTC, and certain European regulators.

Recent Developments

Laws and regulations regarding our business are frequently modified or changed to address perceived problems, new products, or competition or at the request of market participants. The following is a brief discussion of recent regulatory developments that may significantly impact our business.

United States

Equity Market Structure

In December 2022, the SEC released four proposals that could impact equity market structure: (1) Disclosure of Order Execution Information (Rule 605); (2) Regulation NMS Amendments: Tick Size, Access Fees, and Transparency; (3) Regulation Best Execution; and (4) Proposed Rule to Enhance Order Competition. These proposals have been noticed for public comment. If adopted as-is, final implementation of these equity market structure proposals could occur in late 2024 and 2025 and could result in market technology changes and additional compliance costs to Cboe. Further, it is possible that additional proposals or changes to the existing equity market structure, which could have a negative impact on our operations. In addition, bills are sometimes introduced in the U.S. Congress that could also potentially impact equity market structure and adversely impact our volumes and operations. See “Risk Factors” for more information.

Volume Based Pricing Proposal

On October 18, 2023, the SEC released a proposed rule that would impact the way in which volume based discounts are applied (“Volume Based Proposal”). If adopted, this Volume Based Proposal would prohibit national securities exchanges, including Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, from offering volume-based transaction pricing in connection with the execution of agency or riskless principal orders in NMS stocks. Although the new rules do not appear likely to have a near term material impact, the new rules may have a long term material impact on our business, financial condition and operating results if, for example, there is a reduction of overall volumes, liquidity, or market share on Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA. See “Risk Factors” for more information.

Digital Asset Legislation

Members of U.S. Congress have introduced various bills related to the regulation of digital assets, however no legislation has been passed and the details of any potential legislation remain to be discussed and agreed. While some of these contemplated changes could reduce regulatory uncertainty, increase transparency, and promote investor protection, which could be beneficial for Cboe Digital’s volumes and liquidity, the implementation of certain changes could result in a reduction in overall volumes and liquidity or require additional resources to comply with any new rules included as part of the legislation, which could have a negative impact on our operations. See “Risk Factors” for more information.

Europe

Capital Markets Union

The European Council (“E.C.”) has highlighted one of its top priorities as being the establishment of a fully functioning, well-regulated Capital Markets Union (“CMU”). An Action Plan of concrete steps was set out in September 2015, and an update of the list of initiatives was published in September 2016. In November 2019, the E.C. set up a High Level Forum on CMU, resulting in a final report published in June 2020. On September 24, 2020, the E.C. published a new CMU Action Plan, and on November 25, 2021, published a set of legislative proposals in furtherance of the CMU, including proposals to amend the Markets in Financial Instruments Regulation (“MiFIR”) described in the EU Transparency Rules section below. This therefore remains an ongoing project for the E.C., which may result in additional regulation or legislation. In November 2021 the EU Commission published an update regarding progress against the CMU Action Plan alongside a number of new legislative proposals designed to contribute to the objectives of CMU.

Table of Contents

These included proposals to:

Many of the above initiatives have been legislated for and are now in the process of being implemented. Further detail on the MiFIR review is provided below.

OTC Derivatives, Central Counterparties and Trade Repositories

Regulation (EU) No 648/2012 of the European Parliament and of the Council of July 4, 2012 on OTC derivatives, central counterparties and trade repositories (the “European Market Infrastructure Regulation” or “EMIR”) sets out rules relating to over-the-counter (“OTC”) derivatives markets, central counterparties and trade repositories. EMIR was enhanced and amended by EMIR REFIT and EMIR 2.2. In December 2022, the EU Commission published a proposal to further amend EMIR with the primary goal of making EU clearing services more attractive to market participants. This proposal is currently going through the usual legislative procedure.

In addition, regulation governing the authorization and supervision of Central Securities Depositories (“CSDR”) was approved in September 2014, with the publication of most “Level 2” Regulatory Technical Standards in March 2017, with implementation in March 2019. Rules in relation to the calculation and collection of cash penalties have come in to force in February 2022. In November 2022, ESMA published a proposal to amend CSDR to simplify the cash penalties process for cleared transactions. This proposal has since been adopted and will come into force in September 2024. Furthermore, CSDR Refit has been adopted and will come into force from the 1st of May 2024 onwards depending on the specific articles.

The Central Counterparty Recovery and Resolution Regulation (“R&R Regulation”) was published in the Official Journal of the EU on January 22, 2021, which resulted in an increase in the amount of prefunded capital Cboe Clear Europe is required to maintain. This additional prefunded capital is required to be drawn before any recovery measures can be taken by the CCP. On July 12, 2021, and November 18, 2021, ESMA proposed a set of level 2 and level 3 guidance pursuant to the R&R Regulation, which have been adopted by the European Commission and, except for one regulation, have been published in the Official Journal of the EU.

EU Transparency Rules

On November 11, 2021, the European Council (“E.C.”) published its proposal for a review of EU market structure legislation, including proposed amendments to Markets in Financial Instruments Regulation (“MiFiR”) and Directive 2014/65/EU on markets in financial instruments (“MiFID II”). The legislative phase of the review is now almost complete. The final text includes, among other provisions, provision for a consolidated tape for the EU and changes to the transparency regime for equities. These provisions are expected to be implemented in 2025. The legislation, as drafted, does not appear likely to have a material adverse effect on our business, financial condition and operating results. However, there are review clauses contained in the legislation which provide a further opportunity to review the effectiveness of the transparency regime, at which point, potential changes may have a material adverse effect on our business, financial condition and operating results. See “Risk Factors” for more information.

Compliance

U.S. Securities Industry

Federal securities laws have established a two-tiered system for the regulation of securities exchanges and market participants. The first tier consists of the SEC, which has primary responsibility for enforcing federal securities laws. The second tier consists of self-regulatory organizations (“SROs”), which are non-governmental entities that must register with and are regulated by the SEC. The Exchanges are SROs, each registered under Section 6 of the Exchange Act of 1934, as amended (“Exchange Act”) as a “national securities exchange,” and are subject to oversight by the SEC.

SROs are an essential component of the regulatory scheme of the Exchange Act for providing fair and orderly markets and protecting investors. To be registered as a national securities exchange, an exchange must successfully undergo an application and review process with the SEC prior to beginning operations. Among other things, the SEC must determine that the SRO has the ability to comply with the Exchange Act and to enforce compliance by its members and persons associated with its members with the provisions of the Exchange Act, the rules and regulations thereunder and the rules of the exchange.

In general, an exchange SRO is responsible for operating its trading platforms consistent with its rules, and regulating its members through the adoption and enforcement of rules governing the business conduct of its members. The rules of the exchange must also assure fair representation of its members in the selection of its directors and administration of its affairs and, among other things, provide that one or more directors be representative of issuers or investors and not be associated with a member of the exchange or with a broker or dealer. Additionally, the rules of the exchange must be adequate to ensure fair dealing and to protect investors and may not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Exchange Act.

As registered national securities exchanges, virtually all facets of our Exchange operations are subject to the SEC’s oversight, as prescribed by the Exchange Act. The Exchange Act and the rules thereunder impose on us many regulatory and operational responsibilities, including record keeping and the day-to-day responsibilities for market operations and broker-dealer oversight. Furthermore, as SROs, the Exchanges are potentially subject to regulatory or legal action by the SEC or other interested parties. The SEC also has broad enforcement powers to censure, fine, issue cease-and-desist orders, prohibit us from engaging in some of our businesses, suspend or revoke our designation as a registered securities exchange or remove or censure any of our officers or directors who violate applicable laws or regulations. For example, in the past we have entered into consent orders with the SEC, under which our subsidiaries were censured, ordered to cease and desist from violating certain sections of the Exchange Act, paid fines and completed certain undertakings.

As part of its regulatory oversight, the SEC conducts periodic reviews and inspections of exchanges, and the Exchanges have been subject to such routine reviews and inspections. To the extent such reviews and inspections result in regulatory or other changes, we may be required to modify the manner in which we conduct our business, which may adversely affect our business. We collect certain fees to cover Section 31 fees charged to the Exchanges by the SEC and certain fees derived from our regulatory function and fines in connection with our disciplinary proceedings. The Exchanges are responsible for the ultimate payment of Section 31 fees to the SEC. Additionally, under the rules of each of our exchanges, as required by the SEC, any revenue derived from the regulatory fees and fines cannot be used for non-regulatory purposes.

Section 19 of the Exchange Act also provides that we must submit to the SEC proposed changes to any of the Exchanges’ rules, including revisions of their certificates of incorporation, bylaws, or other governing documents of the SROs or their parent companies. The SEC will typically publish the proposal for public comment, following which the SEC may approve or disapprove the proposal, as it deems appropriate. Certain categories of rule changes, like fee changes, can be effective on filing, but the SEC retains the ability to suspend or reject such filings within a prescribed period of time.

Canadian Securities Industry

Cboe Canada Inc. is subject to comprehensive regulation and oversight by its primary provincial securities regulatory authority, the OSC. In addition, Cboe Canada Inc. is a Marketplace Member of, and subject to a regulation services agreement with, CIRO. The regulations applicable to Cboe Canada Inc. cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability.

Australian Securities Industry

Cboe Australia is subject to comprehensive regulation and oversight by ASIC. The regulations applicable to Cboe Australia cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability.

Japanese Securities Industry

Cboe Japan is subject to comprehensive regulation and oversight by the JFSA and the JSDA. The regulations applicable to Cboe Japan cover a wide array of areas, including, but not limited to, marketplace operations (which include corporate governance, fair access, systems compliance and integrity, and conflict management requirements), trading rules, electronic trading risk management, and financial viability.

Futures and Swaps Industry-CFE and Cboe SEF

The operations of each of CFE and Cboe SEF are subject to regulation by the CFTC under the Commodity Exchange Act (“CEA”). The CEA generally requires that futures trading in the United States be conducted on a designated contract market and, in some cases, requires swaps trading to be conducted on a swap execution facility (“SEF”) or designated contract market (“DCM”). The CEA and CFTC regulations establish criteria for an exchange to be designated as a contract market on which futures and futures options contracts may be traded, and for a trading platform to be designated as a swap execution facility on which certain swaps may be traded. Designation as a contract market or swap execution facility for the trading of specified futures or swaps contracts is non-exclusive. This means that the CFTC may permit additional exchanges or trading platforms to be contract markets or swap execution facilities for trading the same or similar contracts.

CFE is a designated contract market, and Cboe SEF is a swap execution facility, each of which is subject to the oversight of the CFTC and to a variety of ongoing regulatory and reporting responsibilities under the CEA. As a designated contract market, CFE is required to comply with the applicable core principles and regulations under the CEA, as is Cboe SEF as a swap execution facility. Each of CFE and Cboe SEF has surveillance and regulatory operations and procedures to monitor and enforce compliance by trading privilege holders with CFE rules, and by participants with Cboe SEF rules, as applicable. If CFE or Cboe SEF fails to comply with applicable laws, rules or regulations, it may be subject to censure, fines, cease-and-desist orders, suspension of its business, removal of personnel or other sanctions, including revocation of CFE’s designation as a contract market or Cboe SEF’s designation as a swap execution facility.

Digital Assets

Cboe Digital Exchange is a designated contract market, and Cboe Clear Digital is a derivatives clearing organization, each of which is subject to the oversight of the CFTC and to a variety of ongoing regulatory and reporting responsibilities under the CEA. As a designated contract market, Cboe Digital Exchange is required to comply with the applicable core principles and regulations under the CEA, as is Cboe Clear Digital as a derivatives clearing organization. Each of Cboe Digital Exchange and Cboe Clear Digital has surveillance and regulatory operations and procedures to monitor and enforce compliance by trading privilege holders with Cboe Digital Exchange rules, and by participants with Cboe Clear Digital rules. If Cboe Digital Exchange or Cboe Clear Digital fails to comply with applicable laws, rules or regulations, it may be subject to censure, fines, cease-and-desist orders, suspension of its business, removal of personnel or other sanctions, including revocation of Cboe Digital Exchange’s designation as a contract market or Cboe Clear Digital’s designation as a derivatives clearing organization.

Cboe Clear Digital also maintains a license to operate as a money transmitter in the states where such licenses or equivalent are required to conduct business. In addition, Cboe Clear Digital has a BitLicense from the NYDFS. As a licensed money transmitter and an entity subject to the BitLicense regulatory regime, Cboe Clear Digital is subject to, among other things, the Bank Secrecy Act, restrictions and requirements with respect to the investment of customer funds and use and safeguarding of customer funds and crypto assets, and bonding, net worth, customer notice and disclosure, reporting and recordkeeping requirements applicable to the company and control persons, and inspection and examination by state regulatory agencies.

Europe

Cboe Europe is located in London and is subject to regulation in the UK and to certain European regulations. The current UK regulatory system was established by the Financial Services Act 2012 (“FSA12”), which amended the Financial Services and Markets Act 2000. The legislation replaced the previous financial services regulator, the Financial Services Authority, with three new bodies: The Financial Policy Committee (“FPC”), The Prudential Regulation Authority, and the FCA. Financial conduct of markets, including activity on, and the operation of, markets is regulated by the FCA, which is an independent non-governmental body, given statutory powers by the FSA12. The FCA has three statutory objectives: to secure an appropriate degree of protection for consumers; to protect and enhance the integrity of the UK financial system; and to promote effective competition in the interests of consumers in the markets for financial services. The FCA is accountable to His Majesty’s Treasury Ministers and, through them, to Parliament.

Cboe Clear Europe and Cboe NL are located in Amsterdam and subject to Dutch law and regulation. The current Dutch regulatory system was established by the Act on Financial Supervision. Financial conduct of markets, including activity on, and the operation of, markets is regulated by the AFM. Financial conduct of CCPs, including clearing activity is regulated by the AFM and DNB. The AFM is an independent non-governmental body, given statutory powers by the Act on Financial Supervision. The AFM has three strategic objectives: to promote the fair and conscientious provision of financial services, to promote the fair and efficient operation of the capital markets and to contribute to the stability of the financial system. The AFM is accountable to the Minister of Finance. The DNB is the Dutch central bank, financial sector supervisor and resolution authority. The DNB is committed to a stable financial system: stable prices, solid financial institutions and properly functioning payment transfers. Cboe Clear Europe is recognized as a non-UK CCP in the United Kingdom, which allows it to provide services to UK Clearing Participants and UK trading venues. Cboe Clear Europe is also recognized as a foreign central counterparty in Switzerland, which allows it to provide services to Swiss Clearing Participants and SIX Swiss Exchange AG.

Much of the UK and Dutch financial services regulation originates from the EU. Such regulation includes organizational requirements, capital resources requirements and the specific requirements for RMs and MTFs and are applicable to both Cboe Europe and Cboe NL. MiFID II and MiFIR set out requirements for RMs and MTFs with respect to the establishment of transparent and non-discretionary rules and procedures governing access and for fair and orderly trading and the efficient execution of orders, as well as to facilitate the efficient settlement of transactions conducted on RMs and MTFs and monitoring compliance with the rules. EMIR governs the CCPs operating in the EU and requires them to meet common risk management, governance and capital adequacy standards. The regulatory functions required of Cboe Europe Equities and Derivatives, including Cboe Clear Europe and Cboe NL, by MiFID II, MiFIR, EMIR and other relevant legislation and regulations are performed by in-house staff. Cboe Europe Equities and Derivatives utilizes the same state-of-the-art, real-time surveillance system is used on the U.S. to monitor trading and market activities on BZX, BYX, EDGA, and EDGX. Cboe Clear Europe utilizes proprietary risk management software to monitor settlement and funding flows.

Global FX

While the global institutional spot FX market remains largely unregulated, the enactment of the Dodd Frank Act and its related regulations in the United States and the ongoing implementation of MiFID II and MiFIR in Europe have impacted the regulatory landscape for currency derivative products. For example, certain standardized currency derivative products are required to trade on an organized trading venue such as a SEF or DCM in the United States or on an MTF or organized trading facility in Europe. Moreover, even in the largely unregulated spot FX market, this movement towards additional trading standards and norms is highlighted by the publication of the FX Global Code in 2017 by the Global Foreign Exchange Committee, reflecting principles of good conduct for the wholesale FX market, and whose publication may lead to additional oversight in the global FX market. Cboe FX issued a Statement of Commitment declaring its commitment to conduct its FX market activities in a manner consistent with the principles of the FX Global Code. Following the publication of the FX Global Code regulators are taking a new look at the spot FX market, and any decision to impose new regulations may affect our spot FX business line.

Broker-Dealers

Cboe Trading, BIDS Trading, and Cboe Fixed Income are registered broker-dealers regulated by the SEC, FINRA, other SROs of which they are members and various state securities regulators. Cboe Trading currently operates as a routing broker-dealer for sending orders from the Exchanges to other venues for execution, including routing orders among the Exchanges. Cboe Trading is considered a facility of each of the Exchanges and is subject to the rules of the Exchanges. The Exchanges are responsible for enforcing Cboe Trading’s compliance with their rules, including to ensure

Cboe Trading is not given preferential treatment. BIDS Trading currently operates an ATS, which is designed to bring counterparties together to anonymously trade large blocks of U.S. equities. BIDS Trading is not a member of any of the U.S. national securities exchanges and is not subject to exchange rules.Cboe Fixed Income, a registered broker-dealer and member of FINRA, operates an electronic trading system for U.S. government securities targeted at the institutional inter-dealer market for trading on-the-run U.S. Treasury bonds and notes in the secondary OTC markets. Cboe Fixed Income’s participants are SEC registered broker-dealers that are members of The Depository Trust and Clearing Corporation’s Fixed Income Clearing Corporation.

Cboe Trading, BIDS Trading, and Cboe Fixed Income are subject to SEC and SRO rules, as applicable, and, as registered broker-dealers, regulations concerning all aspects of their businesses, including trading practices, order handling, best execution, anti-money laundering, handling of material non-public information, safeguarding data, reporting, capital adequacy, record retention, market access and the conduct of their officers, employees and other associated persons. The SEC, SROs and state securities commissions may conduct proceedings which can result in injunctions or other sanctions, censures, fines, the issuance of cease and desist orders or the suspension or expulsion of a broker-dealer, its officers or employees. The SEC and FINRA impose certain minimum capital requirement rules that require notification when a broker-dealer’s net capital falls below certain predefined criteria, dictate the ratio of debt to equity in the regulatory capital composition of a broker-dealer, constrain the ability of a broker-dealer to expand its business under certain circumstances and impose certain requirements that may have the effect of prohibiting a broker-dealer from distributing or withdrawing capital.

In addition, the ATS operated by BIDS Trading is not a registered national securities exchange or a facility thereof, as such, Cboe intends to maintain the BIDS ATS as an independently managed and operated trading venue, separate from and not integrated with the Exchanges. The Chief Executive Officer of BIDS Trading is expected to lead BIDS Trading as an independent business within Cboe, reporting into an independent committee of the board of Cboe Global Markets. Further, Cboe Trading will not route orders to BIDS Trading on behalf of the Exchanges.

Cboe Global Markets

Certain aspects of Cboe Global Markets are also subject to SEC, FCA and AFM oversight, including certain ownership and voting restrictions on its stockholders. The focus of the SEC’s regulation of Cboe Global Markets is to assure fair representation of members in the selection of the directors of the Exchanges, public participation in the governance of the Exchanges and that the Exchanges can satisfy their regulatory responsibilities under the Exchange Act. Furthermore, the SEC requires that Cboe Global Markets give due regard to the preservation of the independence of the self-regulatory function of the Exchanges and to Cboe Global Markets’ obligations to investors and the general public. The SEC also requires that Cboe Global Markets not take any actions that would interfere with the effectuation of any decisions by the Board of Directors of any of the Exchanges relating to its regulatory functions or the structure of the market that it regulates or that would interfere with the ability of such Exchange to carry out its responsibilities under the Exchange Act. To the extent that Cboe Global Markets’ business activities involve or relate to the Exchanges, the officers and directors of Cboe Global Markets may be deemed to be officers and directors of the exchanges for purposes of and subject to oversight under the federal securities laws. Accordingly, the SEC may exercise direct supervision and disciplinary authority over certain Cboe Global Markets’ activities and those activities may be subject to SEC approval and, in some cases, public notice and comment.

In addition, Cboe Global Markets indirectly holds all of the issued share capital and voting rights in Cboe Europe and its wholly-owned subsidiaries, Cboe Chi-X Europe and Cboe NL. As a result, we and any person who holds, or has voting power with respect to, 10% or more of the outstanding shares of Cboe Global Markets common stock may be subject to certain regulatory requirements under UK and Dutch law.

U.S. Regulatory Responsibilities

Our U.S.-based exchanges are responsible for assessing the compliance of their TPHs or members, including Cboe Trading, with the respective exchange’s rules and the applicable rules of the SEC and/or CFTC. The main activities that the exchanges, as applicable, are required to monitor for the purpose of compliance with these rules include:

● surveillance designed to detect violations of exchange trading rules;

● surveillance designed to detect violations of SEC and/or CFTC rules;

● investigation of matters involving potential rule violations;

Table of Contents

In order to ensure market integrity, we regulate and monitor our TPHs’ and members’ trading activities by using both our employees and/or third parties under regulatory services agreements (“RSAs”). See “U.S. Regulatory Agreements” below. Providing effective regulation is important for attracting and retaining the confidence and participation of market-makers, broker-dealers and institutional and retail investors.

We expend considerable time, financial resources and effort to ensure that the exchanges’ rules and regulations conform to regulatory best practices within the securities and futures exchange industries and within the regulatory regime overseen by the SEC and CFTC, our primary U.S. regulators. In order to support our efforts and those of our market participants to comply with applicable law and our exchange rules, we developed a regulatory program to monitor market activity on our exchanges.

All of our Exchanges, CFE, and Cboe Digital Exchange are participants in various cooperative and regulatory information sharing agreements, including in the Intermarket Surveillance Group (“ISG”). ISG is an international information-sharing cooperative governed by a written agreement that provides for a comprehensive surveillance sharing arrangement. In addition to the agreement for confidential information sharing, the ISG provides a framework for the coordination of regulatory efforts among exchanges trading securities, commodity futures and related products to address potential intermarket manipulations and trading abuses.

CFE and Cboe Digital Exchange are also members of the Joint Audit Committee (“JAC”), which is a representative committee of the U.S. futures exchanges and regulatory organizations which participate in a joint audit and financial surveillance program that has been approved and is overseen by the CFTC. The JAC’s primary responsibility is to oversee the implementation and functioning of all terms and conditions of the Joint Audit Agreement and to determine the practices and procedures to be followed by each designated self-regulatory organization in the conduct of regulatory examinations and financial reviews of FCMs.

As part of the regulatory program, each of our Exchanges and CFE have rules pertaining to their respective disciplinary processes.

U.S. Regulatory Agreements

The Exchanges and CFE have entered into agreements under which third parties have agreed to perform regulatory functions on behalf of our markets (e.g., RSAs). As discussed below, in addition, in certain other instances for our Exchanges, a third party has been allocated the regulatory responsibility under Rule 17d-1 or Rule 17d-2 under the Exchange Act, while in others, we retain the regulatory responsibility for the activities.

Regulatory Services Agreement with FINRA

The Exchanges have entered into agreements with FINRA under which FINRA has agreed to provide regulatory services to the Exchanges. Under these agreements, FINRA performs certain regulatory functions on behalf of the Exchanges and, to avoid any potential conflicts of interest concerning the regulation and oversight of Cboe Trading, certain regulatory services specific to Cboe Trading. The Exchanges remain responsible for the regulation of their TPHs, members and marketplaces, and retain the authority for bringing disciplinary actions against their TPHs and members, although FINRA performs certain functions on behalf of the Exchanges. The Exchanges also perform certain regulatory and disciplinary-related functions in-house.

Regulatory Services Agreement with OCC

While CFE also performs most regulatory and disciplinary-related functions in-house, OCC has performed and continues to perform certain regulatory functions on behalf of CFE pursuant to an RSA with CFE. Whether performed under an RSA or in-house, CFE retains overall responsibility for the regulation of its marketplace and for bringing disciplinary actions.

Rule 17d-1 Designations and Rule 17d-2 Agreements

Section 17(d) of the Exchange Act and the related Exchange Act rules permit SROs to allocate certain regulatory responsibilities to avoid duplicative oversight and regulation. Under Exchange Act Rule 17d-1, the SEC designates one SRO to be the designated examining authority (“DEA”) for each broker-dealer that is a member of more than one SRO. The DEA is responsible for the regulatory oversight of applicable financial responsibility rules pertaining to that broker-dealer. Cboe Options is the DEA for several of its TPHs. Cboe Trading’s assigned DEA is FINRA.

Exchange Act Rule 17d-2 permits SROs to enter into agreements, commonly called Rule 17d-2 agreements, which are approved by the SEC and concern the allocation of regulatory responsibility for rules applicable to TPHs and members that those SROs have in common. The Exchanges have entered into certain bi-lateral Rule 17d-2 agreements under which FINRA is allocated responsibility for enforcing certain federal securities laws and certain exchange rules that are common with FINRA rules. The Exchanges have entered into certain other multi-party Rule 17d-2 agreements that allocate responsibility among the participating SROs, which may include the Exchanges, for oversight of their allocated common members compliance with certain rules governing, among other items, options related sales practices, options related market surveillance, insider trading, NMS and consolidated audit trail (“CAT”) NMS plan compliance.

National Market System Plans

We are member participants of several NMS plans including, but not limited to, the following: Cboe Options, C2, BZX, and EDGX are member exchanges in OPRA, which is the designated securities information processor for market information that is generated through the trading of exchange-listed securities options in the United States, and it disseminates certain core trading information, such as last sale reports and quotations. Cboe Options, BZX, BYX, EDGA, and EDGX also participate in the CTA/CQ and the UTP Plans, which perform analogous services for the U.S. equities market. Securities Information Automation Corporation (“SIAC”) acts as the “processor” for OPRA and the CTA/QC Plans. Nasdaq Stock Market, LLC acts as the processor for the Nasdaq Unlisted Trading Privileges Plan. Also, see “Risk Factors” for more information regarding the consolidated data plan order.

Cboe Options, C2, BZX, and EDGX are also parties to the Options Order Protection and Locked/Crossed Market Plan, which is designed to prohibit trade-throughs and avoid locked/crossed markets. Cboe Options, C2, BZX, and EDGX are also parties to the Options Listing Procedures Plan, which sets forth the procedures that the options exchanges must follow to list new options. Cboe Options, BZX, BYX, EDGA, and EDGX are also parties to the NMS plan for the selection and reservation of securities symbols.

Under the Options Regulatory Surveillance Authority Plan (“ORSA Plan”), U.S. securities options exchanges are permitted to act jointly in the administration, operation and maintenance of a regulatory system for the surveillance, investigation and detection of the unlawful use of undisclosed, material information in trading in one or more of their markets. The ORSA Plan is intended to enhance the effectiveness and efficiency with which the exchanges regulate their respective markets and to avoid duplication of certain regulatory efforts. FINRA operates the ORSA Plan facility for options insider trading.

The Consolidated Audit Trail Plan (“CAT Plan”) involves the creation of a consolidated audit trail that tracks orders throughout their lifecycle, which strives to enhance regulators’ ability to efficiently monitor trading activity in Eligible Securities in the U.S. securities markets. Eligible Securities currently include NMS Stocks, Listed Options and OTC Equities. Order and trade data is required to be reported to the CAT central repository the following day by each SRO (a “Plan Participant”) and broker-dealer (an “Industry Member”), along with certain customer and account information by each Industry Member. On November 15, 2016, the SEC approved the CAT Plan and a phased implementation was originally required to begin in November 2017; however, there were some delays. The first phase of CAT (“Phase 1”) ultimately went live in November 2018, at which time we and other SROs/Plan Participants began initial reporting of order and trade file submissions to the CAT. The second phase of CAT (“Phase 2”) for Industry Members began with order and trade file submissions in June 2020. The final Phase 2 implementation sub-phase (Phase 2e), related to Industry Member submissions to the customer and account information submissions system (“CAIS”) has been live in production since April 2022, but its completion has been delayed. The Industry Member full CAIS compliance reporting requirements are currently scheduled to go into effect May 31, 2024.

On May 15, 2020, the SEC adopted amendments to the CAT to establish financial accountability provisions to achieve full CAT implementation, including a financial accountability milestone requiring full implementation of the CAT requirements by December 30, 2022. If the SEC were to determine any financial accountability milestone was not met, it may limit the SROs’/Plan Participants’ recovery of certain costs. Due to the delayed completion of CAIS, the SROs/Plan

Table of Contents

Participants have submitted to the SEC requests to extend the timeline for the completion of Phase 2e and the deadline for the final financial accountability milestone and additional requests may be submitted. If the SEC does not grant extensions and finds that the SROs/Plan Participants did not satisfy the related last financial accountability milestone, it could result in the SROs/Plan Participants not being able to recover certain costs associated with this final sub-phase, which amount of unrecoverable costs may increase for additional delays.

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 Consolidated Audit Trail, LLC (“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 (the brokers responsible for executing each side of the transaction) 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. To date, the funding of the CAT has solely been provided by the SROs/Plan Participants has been done in exchange for promissory notes. The funds generated from the assessment of CAT fees to recover a portion of historical CAT costs will be used by CATLLC to repay a portion of these promissory notes to the Plan Participants.

The Plan Participants submitted fee filings during the first week of January 2024 with the SEC to implement the applicable transaction-based fee rates that are to be assessed by CATLLC to CAT Executing Brokers to recover a portion of historical CAT costs incurred prior to 2022. Additional CAT fees related to other historical CAT costs and to prospective CAT costs are planned to be introduced at a later time through separate fee filings submitted by the Plan Participants. 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 Plan Participants to fund CATLLC in exchange for promissory notes. On January 17, 2024, the SEC issued orders suspending each Plan Participant’s fee filing and instituting proceedings to determine whether to approve or disapprove the fees, which orders were published in the Federal Register on February 13, 2024. Comments are due March 5, 2024, and rebuttal comments are due March 19, 2024.

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.

CATLLC, as well as the Cboe U.S. Securities Exchanges, and certain other exchanges/Plan Participants filed motions to intervene in the aforementioned matter on November 16, 2023 and are waiting the Court’s ruling on the motions. CATLLC also determined to move forward with implementing its first fee under the SEC-approved CAT Funding Model. As a result, the Cboe U.S. Securities Exchanges and other Plan Participants submitted fee filings on or near January 2, 2024 to implement the CAT fee on behalf of CATLLC related to a portion of historical CAT costs incurred prior to 2022 the discussed above. Although the fee filings were submitted as “immediately effective” filings, the CATLLC fee will be assessed beginning with trades occurring on March 1, 2024 (with the first monthly invoice for the month of March being issued in April 2024 and first monthly payment due in May 2024).

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, and until CAT fees assessed by CATLLC to CAT Executing Brokers and Plan Participants to fund prospective CAT costs are implemented, the Plan Participants may continue to incur additional significant costs, including additional promissory notes to fund CAT. Additionally, portions of promissory notes related to the funding of the implementation and operation of the CAT may not be collectible, including if the SEC finds that the SROs/Plan Participants did not satisfy any of the financial accountability milestones. 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. See Note 23 (“Commitments, Contingencies, and Guarantees”) for more information.

Human Capital Management

Cboe has a robust human capital management program in place focused on equal opportunities including diversity, equity and inclusion (“DEI”), performance and career development, health and well-being, comprehensive benefits, training, talent acquisition, and succession planning. Additional information on our approach to human capital and environmental, social, and governance (“ESG”) issues can be found in the Cboe Global Markets, Inc. Environmental, Social and Governance Report located in the Corporate Social Responsibility section of our website at https://markets.cboe.com/about/corporate-social-responsibility, which does not form a part of this Form 10-K.

Equal Opportunity, Diversity, and Pay Equity

Cboe believes in a culture of diversity and inclusion that promotes creativity, collaboration and innovation, which is critical to the success of our business and defining the markets of tomorrow. Cboe is an equal opportunity employer and provides equal employment opportunities to all qualified persons without regard to sex, gender, race, color, ethnicity, creed, religion, national origin, ancestry, citizenship status, age, veteran or military status, disability, marital status, domestic partnership or civil union status, pregnancy, sexual orientation, genetic status, gender identity or expression, and any other characteristic protected by applicable law (a “Protected Characteristic”). Cboe is committed to applying our Equal Employment Opportunity Policy to all employment practices that impact the terms and conditions of employment including, but not limited to, hiring, evaluation, discipline, promotion, training, compensation, transfer, and termination. Actively nurturing and maintaining a diverse and inclusive culture at Cboe is a core imperative. We believe that our collective and unique perspectives fuel our capabilities, enhance our team spirit and enable us to attract and retain top talent as we define the markets of the future. Our commitment and responsibility in this regard starts at the top, with leadership and support from the full Cboe Board of Directors and executive team.

To maintain and strengthen our pledge to equity, diversity and inclusion and to keep a level playing field, we regularly review key touchpoints across the employee journey with Cboe., from the talent selection, promotion, compensation, leadership development, and succession planning processes and make adjustments, as necessary, to help ensure opportunity parity across the Company. Our goal is to ensure that fair pay and equal opportunity for all that results in a collaborative, high performing organization bringing new innovations to market and providing superior service to our customers.

We also have associate resource groups, including the Cboe Women’s Initiative, the Diversity Leadership Council, the Veterans Initiative, PRISM+ (People Respecting Individuality and Sexuality in Markets), Cboe UNIDOS, Asian and Pacific Islanders Network (APIN) and Black Equity and Allyship in Markets (BEAM).

To reinforce our commitment to organization wide education and commitment to diversity and inclusion we also provide harassment and unconscious bias training for employees.

We also have a community engagement program, Cboe Empowers, that provides mentorship, scholarship and guidance to under-resourced students throughout their educational journey through access to Cboe’s associates, resources, work environment and other learning and experience opportunities. Initially launched in Chicago, the vision for Cboe Empowers is to support students through all stages of education from elementary or primary school to career by providing mentorship, learning and experience opportunities, professional development and scholarships to students within the Chicago Public School system and graduates pursuing higher education. Cboe Empowers expects to supplement its own programs by collaborating with local partners, including the Greenwood Project and Working in the Schools, to help create maximum impact for its participants. In 2023, Cboe Empowers awarded seven full-ride college scholarships to under-resourced high school students to attend the school of their choice, expanding the program to include students from Kansas City. Five of the scholarships were awarded to students from Chicago and two were awarded to students from Kansas City.

Performance and Career Development

Cboe expects employees to perform their duties to the best of their ability and to develop their competencies for career growth. We recognize the need to provide ongoing, timely, and constructive performance feedback. Cboe has designed a Performance Management Program that drives the professional development of our employees while also providing fair and equitable rewards and recognition.

The principles of performance management include:

● align performance expectations with strategy and goals of the business,

● ongoing open dialogue regarding performance and development,

● commitment to deliver results which drive our business.

To help promote career development, among other items, Cboe offers a formal mentorship program among its associates. The mentorship program was originally developed by the Cboe Women’s Initiative. In 2023, the mentorship program paired over 60 mentors with mentees across the Company.

Employee Health and Well-Being and Comprehensive Benefits Program

Cboe’s vision is to support the overall wellness of employees and their families through education and activities that encourage a healthy lifestyle, resulting in improved health and productivity. Our programs and benefit plans provide a corporate atmosphere of collective well-being and incorporate strategies for physical, emotional, mental and financial wellness. Our programs include enhanced employee assistance programs, wellness programs and challenges (which address both mental and physical well-being), and webinars and classes through our retirement vendor to support the financial health of our employees.

Table of Contents

With the global pandemic in 2020 and 2021, there was further focus on our Employee Assistance program, which was strengthened across the globe with a diverse set of mental health resources aimed at supporting our employees during a unique and challenging time.

Employee Engagement and Pulse Surveys, Town Halls and an Open-Door Policy

In 2023, Cboe conducted our sixth annual employee engagement survey and has implemented career, leadership, and culture focused programs in response to the survey findings. Our participation rate exceeds standard benchmarks and a significant majority of our employees would recommend Cboe as a great place to work.

Our senior management team continues to hold the commitment to an open-door policy and encourages the free flow of information and communication in furtherance of active transparency. With the recent executive transitions, our ability to tap into the voice of our employees was critically important and we conducted a pulse survey to gauge sentiment. Our CEO also issues weekly letters to help connect with our employees. Human Resources also provided ongoing regular resources and tips to help support the variety of challenges, from the new reality of hybrid work to childcare and elder care, that our employees faced throughout 2023.

Cboe also continues to create an open and frank atmosphere in which any grievance, complaint, suggestion or question receives a timely response. Cboe offers a whistleblower hotline for complaints, which can be made anonymously. Additionally, employees can raise questions and suggestions to the Cboe Human Resources team either in-person or via a group email address and are either responded to individually or addressed at our Global Town Hall meetings. The objective of these town halls is to provide employees an update on Company news, share updates from major business lines, as well as provide a forum to ask questions and offer feedback. Town halls can include updates on anything from legislation that may impact our business to ESG topics. Employees are encouraged to participate in free flow of information and communication and to offer positive and constructive feedback in furtherance of active transparency.

Training and Succession Planning

We believe that the development of all Cboe employees helps drive our collective success. Through skill and competency development we signal our investment in all while also enabling enhanced productivity. Through our tuition reimbursement program, our employees receive financial support in their pursuit of specialized university courses and degrees. In addition to our ongoing offering of online courses on diverse topics through our corporate university, CboeU, employees can participate in the CboeLearns hybrid program focused on virtual classroom instruction combined with work application and CboeLive, which is focused on business topics to foster organizational-wide knowledge sharing and education.

Leadership is another critical element of our success at Cboe. The Board of Directors of Cboe and global senior leaders participated in a Clifton StrengthsFinder assessment and workshop to learn about their leadership style and how to empower Cboe associates based on their natural strengths. Leaders can participate in Lead the Way, Cboe’s leadership development hybrid program focused on virtual classroom instruction combined with in-person facilitated workshops and exercises, and individual development plans leveraging insights for a 360-feedback process. This leadership training program has helped to expand on the development of our high potential leaders, further strengthening the leadership bench and accelerating readiness of this key talent pool.

Cboe has held several succession planning discussions with the Compensation Committee and Board of Directors to plan for the fulfillment of essential roles, such as the CEO and other senior officers. This process includes investments in advanced development planning for targeted successors to accelerate their readiness through key internal projects and assignments as well as tailored training. Diversity and inclusion are a formal part of Cboe’s succession planning process as we work to identify and advance internal diverse talent and, in parallel, continually scan external talent pools for successors. Following the recent executive transitions, one of the new CEO’s top areas of focus is to develop talent and spend time on succession planning.

Item 1A. Risk Factors.

The risks and uncertainties described below are those that we believe are material at this time relating to our business. 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.

Summary of Risk Factors

The following is a summary of the key risks and uncertainties described below that we believe are material to us at this time:

● economic, political and market conditions;

● compliance with legal and regulatory obligations;

● price competition and consolidation in our industry;

● legislative or regulatory changes or changes in tax regimes;

● our ability to attract and retain skilled management and other personnel;

● increasing competition by foreign and domestic entities;

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

● global expansion of operations;

● challenges to our use of open source software code;

● damage to our reputation;

● our ability to maintain an investment grade credit rating;

● the impacts of pandemics;

● litigation risks and other liabilities; and

Risks Relating to Our Business

Loss of our right to exclusively list and trade certain index options and futures could have a material adverse effect on our financial performance.

We hold exclusive licenses to list securities index options on the S&P 500 Index, the Russell 2000 Index, and other indices granted to us by the owners of such indices, and additionally hold exclusive rights to our proprietary VIX Index

Table of Contents

methodology that provides the basis for VIX options and futures. In 2023, approximately 69.2% of our transaction and clearing fees less liquidity payments and routing and clearing costs ("net transaction and clearing fees") were generated by futures and index options, the overwhelming majority of which were generated by products based on exclusively licensed indices (e.g., SPX options) and products based on our proprietary VIX methodology (e.g., VIX options and futures). The bulk of this revenue is attributable to our SPX options and VIX options and futures. As a result, our revenues less cost of revenues are dependent in large part on the exclusive licenses we hold for these indices and our ability to maintain our exclusive proprietary rights in the VIX Index methodology and related products and indices.

There is a risk, with respect to each of our current exclusive licenses, that the owner of the index may not renew the license with us on an exclusive basis or at all. In the first event, we would be subject to multiple listing in the trading of what is now an index product traded by us on an exclusive basis, which could result in a loss of market share and negatively impact our profitability. In the second event, we could lose the right to list the index product entirely. The loss or limited use of any of our exclusive index licenses, especially for the S&P 500 Index, for any reason could have a material adverse effect on our business and profitability.

In addition to the risks related to our exclusive licenses, if we are unable to retain exclusive proprietary rights in the VIX Index methodology and related products and indices, our volatility products could be subject to multiple listing which could have a material adverse effect on us.

The EU has adopted legislation affecting providers and users of benchmark indices in the EU. MiFIR requires benchmarks used to value a financial instrument in the EU to be made available on a non-discriminatory basis to all EU trading venues and central counterparty clearinghouses for the purposes of trading and clearing. As a result, owners of such benchmarks must provide licenses on fair, reasonable and non-discriminatory terms. While similar legislation to MiFIR has not been proposed in the U.S., if it were passed, it could cause us to lose our exclusive rights to list and trade proprietary and licensed index products. Further, in 2018, the EU implemented the EU Benchmark Regulation, which regulates users, data providers and calculators of benchmarks (“administrators”) in the EU, and among other things (subsequent to the transitional period applicable to third country benchmark administrators) prohibits use of benchmarks provided by administrators outside the EU in connection with EU financial instruments unless the administrator is deemed to be subject to an EU equivalent regulatory regime or the benchmark is endorsed or recognized in the EU. These regulations and other emerging regulatory regimes around the world may impact international customers’ interest in or ability to trade index-based products listed on our U.S. exchanges, as well as impact our expansion into foreign trading of our index-based products and our ability to license proprietary indices for use outside of the U.S.

Furthermore, our competitors may succeed in developing, offering and providing a market for the trading of index-based or volatility products, such as cash settled index options or options on ETFs, that are economically similar to those that we offer and they may become successful and take away volume from our products. It is also possible that a third party may offer trading in index-based products that are the same as those that are the subject of one of our exclusive licenses, but in a jurisdiction in which the index owner cannot require a license or in a manner otherwise not limited by our exclusive license. In addition, a diminished perceived attractiveness of or change in demand for any of the indices underlying our products and services, especially the S&P 500 Index, for any reason could have a material adverse effect on our business and profitability.

The value of our licenses to exclusively list index options and futures also depends on the continued ability of index owners to require licenses for the trading of options and futures based on their indices. Although we and other index owners have prevailed in legal actions seeking to challenge our rights to exclusively license indices, we may be subject to changes in the law or other actions taken in the future that might impede our ability to exclusively offer trading in certain index options and futures.

General economic conditions and other factors beyond our control could significantly reduce demand for our products and services and harm our business.

The volume of trading and clearing transactions and the demand for our products and services are directly affected by economic, political and market conditions in the U.S., Europe and elsewhere in the world that are beyond our control, including:

● economic, political and geopolitical market conditions;

● broad trends in business and finance;

● concerns over inflation levels and recessions;

● wavering institutional or retail confidence levels;

Table of Contents

● other legislative and regulatory changes;

● the availability of short-term and long-term funding and capital;

● changes in the level of trading activity in underlying instruments;

● changes and volatility in the prices of securities;

● changes in the volume of foreign currency transactions;

● changes in supply and demand for currencies;

● movements in currency exchange rates;

● the level and volatility of interest rates;

● changes in the financial strength of market participants;

● consolidation among market participants and market data subscribers;

Any of these factors, individually or collectively, could have a material adverse effect on our business, financial condition and operating results by causing a substantial decline in the financial services markets and reducing trading and clearing volumes and demand for market data.

Our business may be adversely affected by price competition.

The securities industry is characterized by intense price competition, especially with respect to transaction fees. We may be required to adjust pricing to respond to actions by new or existing competitors, which could adversely impact our business, financial condition and operating results. We also compete with respect to the pricing of market data and value-added market data, such as historical market data.

In our options segment, the pricing model for trade execution has changed in response to competitive market conditions, and our competitors have adjusted transaction fees and fee structures accordingly, including by opening new exchanges, which allow them to offer multiple pricing models that can appeal to different segments of market participants. These changes have resulted in significant pricing pressures on us, especially on transaction fees and incentives for multi-listed products. As a result of these pricing pressures, our average rate per multi-listed options contract may decrease. It is likely that this pressure will continue and even intensify as our competitors continue to seek to increase their share of trading by further reducing their transaction fees or by offering other financial incentives to order providers and liquidity providers to induce them to direct orders to their markets.

In addition, one or more competitors may engage in aggressive pricing strategies and significantly decrease or completely eliminate their profit margin for a period of time in order to capture a greater share of trading volume. Some order-providing firms on our exchanges have taken ownership positions in options exchanges that compete with us and such exchanges have given those firms added economic incentives to direct orders to them.

With respect to our proprietary products, we compete with futures exchanges and swap execution facilities that offer similar products and other financial market participants that offer over-the-counter derivatives. We also compete against certain multi-listed options products, such as SPY options, which offer some of the features of our proprietary products, such as SPX options.

To attract market share, we may offer “inverted” pricing specials or no-transaction fee trading from time to time, per various fee schedules across our equities exchanges. These forms of promotions, along with other supplemental liquidity programs, may adversely affect our profitability.

Further, regulatory and legal developments, including the new equity market structure proposals and the new Volume Based Proposal could also adversely impact, as applicable, our ability to adjust pricing to respond to actions by new or existing competitors, the amount of liquidity providers can provide, our ability to offer members volume-based pricing. Additionally, in the U.S., we are generally required to file with the SEC any changes to the fees that we charge and in recent years the SEC has more heavily scrutinized pricing changes.

Table of Contents

If we are unable to compete successfully with respect to the pricing of our services and products, our business, financial condition and operating results may be materially and adversely affected. We could lose a substantial percentage of our share of trading if we are unable to price transactions in a competitive manner. Also, our profits could decline if competitive pressures or regulatory changes force us to reduce fees.

A significant portion of our operating revenues is generated by our transaction and clearing-based business. If the amount of trading volume on our markets or clearing volume decreases, or the product mix shifts to lower revenue products, our revenues from transaction and clearing fees will most likely decrease.

In 2023, approximately 71.2% of our revenues less cost of revenues were generated by our transaction and clearing-based business. This business is dependent on our ability to attract and maintain order flow, both in absolute terms and relative to other market centers. If the amount of trading volume on our Exchanges, Cboe Digital Exchange, CFE, BIDS Trading, Cboe Canada Inc., notional value traded on Cboe FX, Cboe SEF, Cboe Europe Equities and Derivatives, Cboe Australia, and Cboe Japan or clearing volumes at Cboe Clear Europe or Cboe Clear Digital decrease, we are likely to see a decrease in fees.

Our total trading or clearing volumes could decline if our market participants reduce their trading or clearing activity for any reason, such as:

● heightened capital requirements;

● transaction tax;

● regulatory or legislative actions;

● reduced access to capital required to fund trading activities;

● consolidation among market participants;

● suspensions of open outcry trading; or

● significant market disruptions.

Over the past few years, a number of legislative actions have been taken, both domestically and internationally, that may cause market participants to be subject to increased capital requirements and additional compliance burdens. These actions, including MiFID II, MiFIR, and the new equity market structure proposals, may incentivize trading away from our markets or cause market participants to reduce trading activity on or routing to our markets.

In addition, the transaction fees generated are different based on type of product and other factors, including the type of customer and certain volume discounts. If the amount of our trading volume decreases, including as a result of the Volume Based Proposal proposed prohibition on volume-based agency tiers, or the mix traded shifts to our lower revenue per contract products, our revenues from transaction fees will most likely decrease. We can offer no assurance that we would be able to reduce our costs to match the amount of any such decrease.

Revenues from our market data fees and access and capacity fees may be reduced due to declines in our market share, trading volumes or regulatory changes.

The occurrence of any event that reduces the amount of market data fees that we receive, whether as a result of fee reductions, fewer members subscribing to the U.S. tape plans or other market data offerings, lack of new products, declines in market share, trading volumes, or notional volumes, or regulatory changes may have a direct negative impact on our business, financial condition, and operating results. For example, if our market share of U.S. listed equities and options or Cboe’s European equities trading volume were to decline, our share of market data fees could also decline. Moreover, market data fees could decline as a result of a reduction in the number of market data users, for example because of consolidation among market data subscribers or due to a decline in professional subscriptions as a result of staff reductions in the financial services industry or otherwise.

Regulatory and legal developments could also impact the fees we receive from market data and access and capacity, or our cost in providing such services. In the U.S., we are generally required to file with the SEC any changes to the fees that we charge for our securities market data products and access and capacity fees. In recent years, certain industry groups have objected to the ability of exchanges to charge for certain market data products. In addition, the SEC and some media have scrutinized market data and market access. As discussed above, the implementation of MDIR or the new equity market structure proposals could cause Cboe’s equities exchanges, BZX, BYX, EDGX, and EDGA, to require additional resources to comply with the new rules, and may have a material impact on our business, financial condition,

Table of Contents

and operating results, including if, for example, there are lower SIP plan revenues or we must reduce the fees or access fee caps we charge.

In addition, the SEC approved a Consolidated Data Plan to replace the three equity data plans that govern the dissemination of real-time, consolidated market data for NMS stocks. While the Consolidated Data Plan order must be resubmitted by SEC, the plan may have a negative impact on the applicable market data revenues that we receive that are generated from such new plan.

We believe Cboe Europe Equities and Derivatives currently offers market data to customers on a non-discriminatory basis at a reasonable cost. As European regulators determine how market data should be disaggregated and what is a reasonable commercial basis for providing market data, it could affect our ability to offer market data products in the same manner that we do today thereby causing an adverse effect on our European market data revenues. While MiFID II and MiFIR aim to encourage a commercial solution to a consolidated tape in Europe, should this fail to materialize, policy makers might be encouraged to implement a mandatory solution that could impact our ability to develop our own commercial offering. As discussed above, the E.C. published provisions for a consolidated tape for the EU, which is expected to be implemented in 2026. As proposed, these provisions may have a material impact on our business, financial condition and operating results if, for example, we must reduce the fees we charge for market data.

The technology upon which we rely, including that of our service providers, may be susceptible to security vulnerabilities or breaches that could harm our business and our role in the global marketplace puts us at heightened risk relative to other public companies.

The secure and reliable operation of our technology, including our computer systems and communications networks, and those of our service providers, market participants, investments, and other third parties, is a critical element of our operations or our business, financial condition or operating results. These systems and networks may be subject to various cybersecurity incidents such as improper or inadvertent access to or disclosure of confidential, commercially sensitive, or personally identifiable information, data theft, corruption or destruction, ransomware, supply chain attack, denial of service attack, malware and other security problems, as well as acts of terrorism, attacks by threat actors including criminal groups, political activist groups and nation-state actors, attacks in connection with geopolitical activity such as the conflicts in Eastern Europe and the Middle East, criminal insider activity, employee error, service provider, market participant or third-party disruptions or security breaches and other events that are beyond our control. Additionally, cyber threats and the techniques used in cyberattacks change, develop and evolve rapidly, including from emerging technologies, such as advanced forms of artificial intelligence (“AI”) and quantum computing. Our increased adoption of remote working, usage of mobile and cloud-based technologies and amount of newly acquired companies and related integrations may increase our risk for a cybersecurity incident. Moreover, given our position in the global financial services industry and as critical infrastructure, we may be more likely than other companies to be a direct target, or an indirect casualty, of such events. While we have experienced in the past, and we expect to continue to experience, cybersecurity threats and events of varying degrees, we are not aware of any of these threats or events having a material impact on our business, financial condition or operating results to date, however we cannot assure you that we will not experience future threats or events that may be material.

We maintain policies, procedures and controls designed to safeguard against cybersecurity incidents and unauthorized access by protecting the confidentiality, integrity, availability and reliability of our systems, networks and information. These policies, procedures and controls are subject to monitoring, auditing, and evaluation practices, pursuant to our Enterprise Risk Management program, which is supported by a three lines of defense approach, and our other governance practices. Further, we developed and maintain cybersecurity and data privacy training programs for our employees and our third-party consultants who have access to our systems. We also conduct simulations, tabletop exercises, and response readiness tests and engage independent third parties on a routine basis to perform cybersecurity penetration assessments. Collectively, these safeguards and measures or those of our third-party providers, including any cloud technologies, may prove inadequate to prevent the attendant risk posed by cybersecurity incidents, subjecting us to contractual restrictions, liability and damages, loss of business, penalties, unfavorable publicity, increased scrutiny by our regulators, and materially impacting our business, financial condition and operating results. We may be required to expend significant resources in the event of any real or threatened breaches in security, including to protect against threatened breaches, to alleviate harm caused by an actual breach, and to address any reputational harm or litigation or regulatory liability. Despite our cybersecurity measures, security vulnerabilities or breaches may remain undetected for an extended period of time. As a result of our ongoing risk management and related assurance activities, we have identified, addressed, and continue to address potential security vulnerabilities and/or internal control weaknesses. We are not aware of any of these vulnerabilities having a material impact on our business, financial condition or operating results to date. However, we cannot provide assurance that any future vulnerabilities, internal control weaknesses, or events that

Table of Contents

may be experienced will not be material. Such harms also could cause us to lose market participants, experience lower trading volume, and negatively impact our competitive advantage and business, financial condition and operating results.

Additionally, as threats continue to evolve and increase, as we continue to expand ongoing risk management and related assurance activities, and as the domestic and international regulatory environment related to cyber security and data protection becomes increasingly rigorous, we may be required to devote significant additional resources to modify and enhance our security controls and to identify and remediate any security vulnerabilities. Those additional resources could have an adverse effect on our business, financial condition and operating results.

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 and compensation inflation. 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 September 18, 2023. Further, on July 6, 2023, Brian N. 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 M. Griebenow, Senior Vice President, 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. Additionally, on October 12, 2023, Catherine R. Clay was appointed to serve as Executive Vice President, Global Head of Derivatives and Adam Inzirillo was appointed to serve as Executive Vice president, Global Head of Data and Access Solutions. 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.

Intense competition could materially adversely affect our market share and financial performance.

The market for trade execution services, clearing and products is intensely competitive in the asset classes and geographies in which we operate. Increased competition may result in a decline in our share of trading activity and a decline in our revenues from transaction and clearing fees and market data fees, thereby materially adversely affecting our operating results. We compete with a number of entities on several different fronts, including the cost, quality and speed of our trade execution, functionality and ease of use of our trading and clearing platforms, range of our products and services, our technological innovation and adaptation and our reputation. In particular, we have seen increased competition from off-exchange venues, which have increased their share of trading activity. See “Business – Competition” for more information.

Some of our competitors and potential competitors have greater financial, marketing, technological, personnel and other resources than we do. These factors may enable them to develop similar or more innovative products, to offer lower transaction and clearing fees or better execution to their customers or to execute their business strategies more quickly or efficiently than we can. In addition, our business, financial condition and operating results may be materially adversely affected if we cannot successfully develop, introduce and/or market new services and products or if we need to adopt costly and customized technology for our services and products.

Table of Contents

Furthermore, new or existing competitors may:

● respond more quickly to competitive pressures;

● develop and expand their technology and service offerings more efficiently;

● provide better, more user-friendly and more reliable technology;

● take greater advantage of acquisitions, alliances and other opportunities;

● market, promote, bundle and sell their products and services more effectively;

If our products, markets, services and technology are not competitive or we fail to anticipate or respond adequately to changes in technology, customer preferences and regulatory requirements or we encounter any significant delays in product development efforts our business, financial condition and operating results could be materially harmed.

We depend on third-party service providers for certain services that are important to our business. An interruption, significant increase in fees or cessation or impairment of such service by any third party could have a material adverse effect on our business, financial condition and operating results.

We depend on a number of service providers, including clearing organizations such as OCC, NSCC, DTC, CDS, LCH, Cboe Clear Europe, and Cboe Clear Digital, our wholly-owned subsidiaries, JSCC, ASX Clear Pty Ltd, and SIX x-clear; securities information processors such as the CTA, UTP Securities Information Processor and OPRA; regulatory and other service providers such as FINRA and OCC; the hosts of our data and disaster recovery centers; and various vendors of communications and networking products and services. In addition, we also depend on third party routing and clearing firms that are involved in processing transactions on our behalf. More specifically:

Table of Contents

With respect to options, all contracts traded on our exchanges must be cleared through clearing members of OCC. At December 31, 2023, there were 117 TPHs that are clearing members of OCC. Three clearing members accounted for approximately 79.6% of transaction and other fees collected through OCC in 2023. Additionally, the three largest clearing members clear the majority of the market-maker sides of transactions at Cboe Options, C2, BZX, EDGX and at all of the options exchanges. Should one of these clearing members or liquidity providers exit the business or withdraw from our options exchanges, impose additional market-maker financial requirements or if market-makers were unable to transfer to another clearing member or other liquidity providers were unable to provide additional liquidity, this could create a significant disruption to the options markets, including ours.

We cannot provide assurance that any of these providers will be able to continue to provide these services in an efficient manner or that they will be able to adequately expand their services to meet our needs. An interruption or malfunction in or the cessation or impairment of an important service by a third party or disruption of a third party’s operations could cause us to halt trading in some or all of our products or our services, make us unable to conduct other aspects of our business, cause us to experience the loss of a significant number of market participants or cause us to experience a significant reduction in trading activity on our options and futures markets, each of which could have a material adverse effect on our business, financial condition and operating results. In addition, our inability to make alternative arrangements, such as moving clearing to another clearing agency, in a timely manner, or at all, could have a material adverse impact on our business, financial condition and operating results.
