Cboe Global Markets (CBOE) Risk Analysis

Changes in regulation by the SEC, CFTC, FCA, DNB, AFM, CIRO, OSC, ASIC, JFSA, JSDA, other domestic and foreign regulators or other government action, including approval by these regulators of rule filings or initiatives by other SROs or entities, including OCC, could materially affect our markets, products and clearinghouse. In recent years, the securities and derivatives industries have been subject to regulatory changes as a result of increasing government and public scrutiny of the securities and derivatives industries. We have also experienced, and we may continue to experience due to changes in administrations in the jurisdictions that we operate and expansion into other asset classes, such as SFT, and geographies, an increase in rulemaking and legislation that could affect our business. In particular, 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. Each of these proposals have been noticed for public comment, and in 2024, Rule 605 and the Tick Size/Access Fee Cap proposals were approved by the SEC and await implementation. Rule 605 and Tick Size/Access Fee Cap rule may result in increased technology and compliance costs to Cboe. This rule is also likely to result in increased technology and compliance or challenge costs to Cboe, as well as potential adverse impact to Cboe's trading volume and transaction fee revenue. The SEC has yet to take any additional action on Regulation Best Execution and Order Competition, but if adopted as-is, these proposals could result in market technology changes and additional compliance costs to Cboe, and have a material impact on our business, financial condition, and operating results. Further, on October 18, 2023, the SEC released the Volume Based Proposal and, although the proposed new rules do not appear likely to have a potential near term material impact, the new rules, if adopted as-is, 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 Note 23 ("Commitments, Contingencies, and Guarantees - Legal Proceedings") for more information. Under EU and UK regulations, European and UK banks and other European and UK financial institutions become subject to punitive capital charges if they transact options or futures through a third country central counterparty ("CCP") that is not recognized in the applicable jurisdiction. OCC is recognized as a third country CCP by the EU and is currently operating under the UK's temporary recognition regime. Although the UK has not issued any equivalency determination with respect to U.S. CCPs, OCC has submitted its application for permanent recognition in the UK. The current deadline for recognition in the UK is December 31, 2025, and may be extended by His Majesty's Treasury in the future in increments of 12 months each. As a prerequisite to ultimately achieving recognition in the UK, it is possible that OCC could be required by the UK to contribute capital to its default waterfall applicable in the event of clearing member default. This capital could be required to be drawn before the default fund contributions of non-defaulting clearing members in the event that a defaulting clearing member's margin and other contributions were to be exhausted. OCC's stockholders, including Cboe Options, could effectively be required to fund this capital. If the UK does not recognize OCC as a third country CCP, then UK market participants that clear through OCC would become subject to punitive capital charges. As a result, we could experience the loss of a significant number of UK market participants and a significant reduction in trading activity on our options and futures markets, which could have a material adverse effect on our business, financial condition, and operating results. The implementation of MiFID II and MiFIR in Europe at the beginning of 2018 has encouraged competition among market centers in Europe. MiFID II and MiFIR have introduced a number of new rules, including enhanced internal organizational and compliance monitoring requirements, which apply directly to European trading venues such as our MTF and RM. The impact of MiFID II and MiFIR is significant, and the increased competition among market centers could reduce trading fees, while increasing our costs of operating in Europe. Additionally, European authorities are currently undertaking a review of MiFID as a result of which new rules may come into effect that could have a material impact on our business. In 2021 the E.C. published proposals for the review of EU market structure, including provisions for a consolidated tape for the EU and changes to the transparency regime for equities. These proposals are expected to be implemented during 2026. As proposed, these new rules may have a material adverse effect on our business, financial condition, and operating results. The legislative and regulatory environment in which the spot FX market operates is evolving and has undergone significant changes in the recent past, and there may be future regulatory changes in the spot FX industry. The FX Global Code was published in 2017, and re-affirmed in 2021, and sets forth standards of conduct agreed by market participants and central banks on a global basis to apply to the wholesale FX market, and the effect of its publication on conduct and future regulation continues to evolve. 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. Amendments to the FX Global Code, changes in the interpretation or enforcement of existing laws and regulations by applicable governmental bodies and regulatory organizations, or the adoption of new legal or regulatory requirements, may also adversely affect our spot FX business. Further, our FX NDF business may also be adversely affected by proposed regulatory changes to the rules governing swap execution facilities. It is also possible that there will be additional legislative, regulatory, and enforcement changes, priorities or efforts in the environment in which we operate, or plan to operate, our businesses. Actions on any of the specific regulatory issues currently under review in the U.S. or internationally and other proposals could have a material impact on our business. In addition, U.S. and foreign legislatures and regulators could impose legislative or regulatory changes that could materially adversely impact the ability of our market participants to use our markets or participate in the securities industry at all. Any such changes could result in the loss of a significant number of market participants or a reduction in trading activity on our markets, either of which could have a material adverse effect on our business, financial condition, and operating results. Changes or proposed changes in regulation may also result in additional costs of compliance and modification of market participants' trading activity on our Exchanges and markets.

Our Exchanges registered with the SEC must submit proposed rule changes to the SEC for its review and, in many cases, its approval. Even where a proposed rule change may be effective upon filing with the SEC, the SEC retains the right to suspend and disapprove such a rule change. Also, the CFTC may stay or disapprove rules that we file with it for Cboe Clear U.S., Cboe Digital Exchange, CFE, or Cboe SEF. The rule review process can be lengthy and can significantly delay the implementation of proposed rule changes that we believe are necessary to the operation of our markets. If the SEC or CFTC delays, including because of a government shutdown, or does not allow one of our Exchanges to implement a rule change, this could negatively affect our ability to make needed changes or implement business activities. Similarly, the SEC must approve amendments to our exchange subsidiaries' certificates of incorporation and bylaws as well as certain amendments to the certificate of incorporation and bylaws of Cboe Global Markets. The SEC may decide not to approve a proposed amendment or may delay such approval in a manner that could negatively affect our ability to make a desired change, which could prevent or delay us from improving the operations of our markets or recognize income from new products.

As a competitive business with regulatory responsibilities, we are responsible for disciplining TPHs and members for violating our rules, including by imposing fines and sanctions. This may create competing interests between our business interests and our regulatory responsibilities. Any failure by us to fulfill our regulatory obligations could significantly harm our reputation, increase regulatory scrutiny or cause the SEC or CFTC to take action against us, all of which could materially adversely affect our business, results of operations or financial condition.

We are a party to a number of license agreements that permit us to list tradeable products related to various indices that are among the most actively traded products on our exchanges. We also enter into agreements pursuant to which we act as an index provider and calculate and disseminate proprietary indices and other values. We believe that demand for our products is based in part on market perception of the quality and integrity of these indices. The quality and integrity of these indices are dependent on the ability of index providers, including us, to properly maintain the indices. Maintenance includes ongoing index calculation and index rebalancing, and depends on data providers for a number of things, including the timely provision of accurate input data. We also rely on index providers to enforce intellectual property rights against unlicensed uses of the indices and uses of the indices that infringe on our licenses. Some of our agreements concerning our proprietary products obligate the parties to those agreements to provide important services to us. If any of our index providers, including us, are unable to maintain the quality and integrity of indices, or if any of the index providers or service providers, including us, fail to perform their obligations under the agreements, trading in derivative products, and therefore transaction fees we receive, may be materially adversely affected or we may not receive the financial benefits of the agreements that we negotiated. Differences in the calculations from methodologies described in published materials or incorrect calculations of our indices or the failure to implement any planned remedial changes may result in the loss of perceived quality and integrity of our indices, loss of demand for our products, increased potential for investigations and enforcement proceedings, increased potential for failure to perform our obligations under agreements concerning our products or in our capacity as an index provider, and increased exposure to third party claims and related litigation expenses, which could have a material adverse effect on our business, financial condition, and operating results.
