CME Group products are traded primarily through CME Globex, as well as by open outcry in Chicago for SOFR options and through privately negotiated transactions.

We strive to provide the most flexible and scalable platforms to support the operational and capacity needs of our business along with the delivery of innovative technology solutions to the marketplace. Our CME Globex electronic trading system operates our central limit order book (CLOB) markets. The CME Globex platform is accessible through a wide variety of vendor-provided and custom-built trading systems that benefit from our open application programming interface approach. For electronic and privately negotiated markets, we offer brokers and customers the CME Direct platform for arranging, executing, recording and risk-managing trades across all six major asset classes. We also provide the functionality to connect to CME Direct on a mobile device through our CME Direct Mobile application with full trading and on-the-go order management capabilities.

Together, our platforms offer:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• certainty and flexibility of execution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• extensive capabilities to facilitate complex and demanding trading;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• direct market access;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• open access, price transparency and anonymity;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• convenience and efficiency;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• connectivity through highly secure, resilient and low-latency network options;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• access to market data; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• global distribution, including connectivity through high-speed international telecommunications hubs in key financial centers.

We maintain comprehensive business continuity and disaster recovery plans, as well as facilities designed to enable timely recovery and resumption of our markets in the event of a business disruption or disaster. We also maintain incident and crisis management plans that address responses to disruptive events.

The customer base of our derivatives exchanges includes professional traders, financial institutions, institutional and individual investors, major corporations, manufacturers, producers, governments and central banks. Customers may be members of one or more of our exchanges. Rights to directly access our derivatives markets will depend upon the nature of the customer, such as whether the entity or individual is a member of one of our exchanges or has executed an agreement with us for direct access.

U.S. trading rights and privileges are exchange-specific. Open outcry trading is conducted exclusively by our members. Membership on one of our derivatives exchanges also enables a customer to trade specific products at lower fees. Under the terms of the organizational documents of our exchanges, our members have certain rights that relate primarily to trading right protections, certain trading fee protections and certain membership benefit protections. In 2025, 85% of our contract volume was from trades by our members.

***Derivatives Clearing Business:*** Through our derivatives clearing house, operated by CME, we provide clearing and settlement services for a broad range of exchange-traded futures and options on futures contracts, exchange-traded swaps and OTC derivatives. The CME ClearPort front-end system provides access to our flexible clearing services over multiple asset classes. Our integrated clearing function is designed to ensure the safety and the soundness of our derivatives markets by serving as the counterparty to every trade, becoming the buyer to each seller and the seller to each buyer, and limiting counterparty credit risk. The clearing house marks open positions to market at least twice each business day, requiring payments from clearing firms whose positions have lost value and making payments to clearing firms whose positions have gained value. For select cleared-only markets, positions are marked-to-market once each business day, with the capacity to mark-to-market more frequently as market conditions warrant. For physically-delivered exchange-traded derivatives contracts, if a clearing firm fails to fulfill a delivery obligation, the clearing house is responsible for covering the replacement cost to the clearing firm whose actions or omissions did not cause or contribute to the delivery failure. The clearing house has adopted processes to monitor for potential operational risks relating to the delivery of these physically-delivered contracts.

The majority of clearing and transaction fees received from clearing firms represents charges for trades executed and cleared on behalf of their customers. One firm represented 12% of our clearing and transaction fees revenue for 2025. In the event a clearing firm were to withdraw, our experience indicates that the customer portion of the firm's trading activity would likely transfer to one or more other clearing firms of the exchange.

***Securities Clearing Business:*** In December 2025, our subsidiary, CME Securities Clearing Inc. (CMESC) received approval from the U.S. Securities and Exchange Commission (SEC) to become a securities clearing agency. The goal is for CMESC to help market participants comply with the upcoming SEC clearing requirements for U.S. Treasury transactions (as of December 31, 2026) and repo transactions (as of June 30, 2027). We expect to launch this service later in 2026 and position the company to offer additional capital and operational efficiencies to its clients.

***Cash Markets Business:*** Our cash markets business comprises BrokerTec and EBS, primarily operated on CME Globex. BrokerTec and EBS offer anonymous and disclosed trading venues, offering clients multiple execution and distribution options and the benefit of an established and far-reaching distribution network of liquidity providers and consumers. BrokerTec and EBS are fully integrated with all major ISVs for order entry and staging as well as post trade for clearing and settlement, offering an efficient and fully electronic end-to-end trade workflow solution. Certain BrokerTec products are cleared through third-party clearing houses.

BrokerTec operates global electronic trading for fixed income and money market products, with a leading position in cash U.S. Treasuries, European Government Bonds, and Repo on European Union (EU), United Kingdom (UK), U.S. and other international G10 governments, emerging market fixed income instruments and Supranational and Agency Bonds. It facilitates trading for banks and non-bank professional trading firms, offering a dealer-to-dealer electronic trading platform operated on CME Globex. In 2025, we launched BrokerTec Chicago, a second CLOB for cash U.S. Treasuries co-located with our U.S. Treasury futures and options markets, to support trading between cash and derivatives markets. We also offer request-for-quote trading via BrokerTec Quote offering a dealer-to-client trading solution for the global government bond repo (including Emerging Markets) and credit repo markets. BrokerTec Quote also offers securities lending in European debt.

EBS provides for the trading of global FX products across major and emerging market currencies and Spot Precious Metals. EBS Market is a CLOB electronic trading platform for spot FX, Spot Precious Metals and non-deliverable forwards. EBS Direct is a relationship-based trading platform offering Spot FX and Spot Precious Metals. In 2025, we launched FX Spot+, a trading platform that connects the over-the-counter (OTC) spot FX market with the deep liquidity of our FX futures complex.

***Data Services Business:*** We offer a variety of data products and services through industry-leading data platforms and third-party distribution partners, which are designed to meet the risk-management, trading, investment and business needs of our global customer base. To this end, we provide proprietary real-time and historical market data related to CME Group's deeply liquid futures and options on futures exchanges and cash markets businesses. We further offer derived cash markets pricing, third-party and alternative data sets, as well as a wide range of analytic tools. As customers continue to leverage cloud technology to improve and evolve their businesses, CME Group has taken a leading role by becoming the first derivatives marketplace to provide live market data natively on the Google Cloud. CME Group is also the distributor of leading benchmark equity and commodity indices on behalf of third parties, as well as a distributor and licensor of our own proprietary benchmarks and indices, including CME Term SOFR Reference Rates (CME Term SOFR) and Term €STR Reference Rates, which adhere to the International Organization of Securities Commissions Principles for Financial Benchmarks and are administered by our UK regulated subsidiary, CME Benchmark Administration Limited (CME Benchmark).

**Our Strategic Initiatives** 

The following is a description of our strategic initiatives:

***Maximize Futures and Options Growth Globally* —** Our strategy for driving growth and new customer acquisition centers on expanding, innovating and scaling our core offerings and increasing participation from customers. To achieve this, we focus on several key areas: optimizing our global sales team, cross-selling select products, launching new products and services while strengthening our existing product and service offerings, securing intellectual property rights to new products, enhancing our relationships and broadening our base of distribution partners, improving our data distribution capabilities, and deepening open interest in our core futures and options offerings.

In 2025, CME Group futures and options had record average daily volume (ADV) of 28.1 million contracts. This included a third consecutive year of volume records in our interest rates asset class, as well as volume records for our agricultural, energy and metals products. In 2025, we experienced significant year-over-year ADV growth in recently launched products, including 32% growth in micro products and 11% growth in OTC alternative products, with more new products in the pipeline for 2026. Our product growth strategy is centered on the following key elements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We list products at the micro size across all six major derivatives asset classes. These products are designed to attract a new customer base.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our options franchise continues to experience rapid volume growth, with new product launches gaining positive traction.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have expanded into Credit, Treasury bills and TBA (To-Be-Announced) Mortgage futures building on our strong foundation in U.S. Treasuries and SOFR.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have expanded trading to 24 hours a day, seven days a week for certain event contracts. We will begin offering 24/7 trading for our entire crypto suite in Q2 2026 to enable our customers to hedge exposure to the underlying cash markets for these products throughout the weekend.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are establishing a leadership position in and supporting the needs of our clients in the energy transition/environmental markets by expanding into bioenergy, water, battery metals and carbon products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our introduction of more granular futures and options on futures contracts, such as those focused on specific seasons, events, weekly, or daily periods, is enabling our clients to execute more precise hedging strategies and generates additional spreading opportunities in conjunction with our current product offerings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our OTC alternative product suite brings traditional OTC functionality to CME Group market participants and assists with the growing need for operational and capital efficiencies.

We are also focused on both expanding and deepening our global customer base by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Offering our broad and diversified portfolio of benchmark products worldwide. Our significant investment in the expansion of our sales organization has resulted in a presence in over 10 countries, including our most recent expansion into the Middle East with the opening of a Dubai office. Moreover, we are committed to providing products that are regionally relevant.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We continue to target cross-asset opportunities across client segments and across cash and futures platforms in an effort to drive sales and generate new client participation across all regions. In 2025, approximately 31% of our electronic futures and options volume was from transactions reported as outside the U.S. and approximately 53% of our market data revenue was derived from outside the U.S. We also achieved 6% growth in trading volume during European trading hours and 13% growth during Asia Pacific trading hours in 2025 compared to 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We continue to add new channel partners to help us expand the reach of CME Group offerings. We have a broad distribution network around the globe comprised of a combination of internal and external channels and proprietary front-end capabilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Enhancing our retail strategy focusing on the growth of top-tier and large new-to-futures brokers and broadening our contract offerings to better align with the investment strategies favored by retail traders. Our joint venture with FanDuel, a part of Flutter Entertainment plc, launched in December 2025. This partnership introduced a new prediction markets application designed for retail customers. The application offers access to our simplified event contracts covering both major financial and economic benchmarks and sporting events.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Introducing new services and tools to assist our clients in managing their risks. We have a history of providing customer value and responsiveness and believe our products and services position us to help our customers adapt to and comply with new regulations, while enabling them to efficiently manage their risks. For example, in 2025, we launched CME FX Spot+ and BrokerTec Chicago.

***Diversify our Business and Revenue*** - In addition to our focus for growing and strengthening our core futures and options franchise, we also strive to diversify our business and revenues.

Through the acquisition of NEX, we added our cash markets business (BrokerTec and EBS), which generated $283.7 million of clearing and transaction fees in 2025.

CME Group is well-positioned to capitalize on its ability to license CME Term SOFR, administered by CME Benchmark. CME Term SOFR is the only SOFR rate endorsed by the Alternative Reference Rates Committee and the Federal Reserve Board has formally endorsed the forward-looking term rates based on SOFR.

Through our joint venture with S&P Global, S&P Dow Jones Indices LLC, we have a long-term, ownership-linked, exclusive license to list futures and options based on the S&P 500 Index and certain other S&P indices. S&P Dow Jones Indices LLC combines the world class capabilities of the S&P and Dow Jones Indices and is a significant player in passive investing, including the exchange-traded fund (ETF) industry value chain and offers leading fixed income and credit indices, such as iBoxx, iTraxx and CDX. We act as the joint venture's licensing agent and distribution services provider.

***Deliver Unparalleled Customer Efficiencies and Operational Excellence* -** With changing regulatory requirements for many of our customers, including additional margin requirements on uncleared trades, and the need for greater efficiencies, we have added tools to enable customers to manage clearing positions in our markets in an efficient manner. With the ongoing

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

implementation of regulatory reform in the U.S. and in Europe, along with global implementation of Basel III capital requirements on financial institutions, we expect centralized clearing and capital efficiencies to continue to be important for our global client base.

We provide a comprehensive multi-asset-class clearing solution to market participants for maximum operational ease and the capital efficiency that comes with connecting to our derivatives clearing house. Our clearing services offer the ability to optimize collateral and capital efficiencies across portfolios within the clearing house while meeting the heightened regulatory requirements on derivatives. The majority of our clearing volumes and activities are related to our listed futures and options, which represent the majority of our open interest and collateral held against these positions. We also offer clearing services for event contracts, OTC interest rate swaps, FX forwards and commodity swaps.

In 2023, we launched our SPAN 2 methodology and functionality, an enhancement to our original Standard Portfolio Analysis of Risk (SPAN) margin framework which has been the industry standard for margining. SPAN 2 is designed to respond to increasing demands on margin methodologies due to the growth in the diversity and complexity of products and the greater need for portfolio and capital efficiencies. Like its predecessor, SPAN 2 uses a value-at-risk approach, leveraging historical data to model potential value changes (gains or losses) for a position or portfolio across various risk scenarios. As of the end of 2025, the SPAN 2 framework has been implemented for our energy and equity products, with plans to transition interest rates, FX, agriculture and commodities. During the transition, customers can continue to use the SPAN margining system, which supports both the current and enhanced methodologies inside the system. The clearing house offers a range of margin services tools to enable customers to analyze their portfolios and determine the potential impact of the SPAN 2 framework on their margin requirements.

Our commitment to providing customers with valuable opportunities for operational and capital efficiencies has resulted in significant market savings estimated at billions of dollars daily. In 2025, the average daily margin saving was approximately $72 billion.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Applied Offsets: Applying offsets across correlated futures and options on futures contracts across all asset classes traded at CME Group.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Portfolio Margining: Offering margin offsets between futures and options on futures and cleared OTC instruments with common risk factors.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cross-Margining Programs: These programs provide portfolio margin efficiencies and reduce performance bond requirements by offsetting positions between two clearing houses. We have established arrangements with the Fixed Income Clearing Corporation (FICC) and the Options Clearing Corporation (OCC). We have enhanced our arrangement with FICC through the partnership with The Depository Trust & Clearing Corporation (DTCC) to offer enhanced capital efficiencies to our eligible clearing firms. Eligible clearing firms of CME and the Government Securities Division of DTCC's FICC can now cross-margin an expanded suite of products, including CME Group SOFR futures, Ultra 10-Year U.S. Treasury Note futures and Ultra U.S. Treasury Bond futures, with FICC-cleared U.S. Treasury notes and bonds and certain repo transactions. We are working with FICC to receive regulatory approval to extend the existing cross-margining arrangement to end-user clients of eligible clearing firms. We plan to establish a future cross-margining arrangement between CMESC and our derivatives clearing house, operated by CME, with the intention of providing offsets between cleared cash U.S. Treasuries and repo transactions and our interest rate derivatives products.

We also provide compression via coupon blending as well as CME CORE (Clearing Online Risk Engine), an interactive margin calculator that enables clients to optimize their capital by providing insights on margin requirements prior to trading.

***Partnership with Google Cloud -*** In 2021, we entered into a 10-year strategic partnership with Google Cloud to accelerate our move to the cloud. This initiative is expected to transform derivatives markets by expanding access and creating efficiencies for market participants. Significant progress was achieved during 2025 in moving our core, non-latency sensitive applications, including those supporting clearing and market data, to the Google Cloud. We anticipate completing the migration of the applications supporting clearing by the end of the first quarter of 2026, followed by the decommissioning of the legacy on-premises applications. Operating our applications from the Google Cloud allows for a more efficient process to commercialize and launch new products and services. We have also advanced the preparations to move our markets to Google Cloud. Google Cloud is developing a new private cloud region and a co-location facility in Aurora, Illinois. This facility will host Google Cloud's platform designed to support the global trading of CME Group's futures and options markets in the cloud with next-generation cloud technology, ultra-low-latency networking and high-performance computing. In addition to our state-of-the-art trading infrastructure, our clients will also be able to utilize Google's artificial intelligence and data capabilities to help develop, test and implement trading strategies to manage their risk more efficiently.

**Patents, Trademarks and Licenses**

We own the rights to a large number of trademarks, service marks, domain names and trade names in the U.S., Europe and other parts of the world. We have registered many of our most important trademarks in the U.S. and other countries. We hold the rights to a number of patents and have a number of patent applications pending. Our patents cover match engine, trader user interface, trading floor support, market data, general technology and clearing house functionalities. We also own copyrights to a variety of materials. Those copyrights, some of which are registered, include printed and online publications, websites, advertisements, educational materials, graphic presentations and other literature, both textual and electronic. We protect our intellectual property rights by relying on trademarks, patents, copyrights, database rights, trade secrets, restrictions on disclosure and other methods.

We offer equity index futures and options on key benchmarks, including S&P, Nasdaq, Dow Jones, FTSE Russell and fixed income index futures. These products are listed by us subject to license agreements with the applicable owners of the indexes, some of which are exclusive. In connection with S&P Dow Jones Indices, we have a license agreement (S&P License Agreement) for certain S&P stock indices and related trade names, trademarks and service marks in connection with the creation, marketing, trading, clearing and promoting of futures contracts and/or options on futures contracts that are indexed to certain S&P stock indices. Our license for the S&P 500 Index will be exclusive for futures and options until one year prior to the termination of the S&P License Agreement, and non-exclusive for the last year. The license for the other S&P stock indices is generally exclusive for futures and options. The term of the S&P License Agreement will continue until the date that is one year after the date that CME Group ceases to own at least 5% (accounting for dilution) of the outstanding interests in S&P Dow Jones Indices. Upon the occurrence of certain events, including certain terminations of the joint venture, the term may be extended up to an additional ten years. In connection with S&P Dow Jones Indices, we also have an exclusive license agreement (Dow Jones License Agreement) for certain Dow Jones indices. The initial term of the agreement is through June 30, 2026. Following the initial term, the Dow Jones License Agreement will automatically renew for renewal terms of five years thereafter, so long as there is open interest in any of CBOT's or its affiliates' products based on one or more of the Dow Jones licensed indices. In the event there is no open interest in any such products, then we may terminate the agreement. We also have exclusive license agreements for certain Nasdaq indices through 2039 and for certain Russell indices through 2037. We pay the applicable third-party a revenue share under the terms of these licensing agreements. A copy of the S&P License Agreement has been filed as a material contract.

Additionally, CME Group is the distributor of CME Term SOFR, a daily set of forward-looking interest rate estimates, calculated and published for 1-month, 3-month, 6-month and 12-month tenors and administered by CME Benchmark.

We cannot guarantee we will be able to maintain the exclusivity of our licensing agreements with S&P, Dow Jones, Nasdaq and FTSE Russell or that any renewal will be on terms as favorable to us. In addition, we cannot guarantee that others will not succeed in creating stock index futures based on information similar to that which we own or have obtained by license, or that market participants will not increasingly use other instruments, including securities and options based on the S&P, Dow Jones, Nasdaq or FTSE Russell indices, to manage or speculate on U.S. stock risks or that clients select another interest rate alternative. Parties also may succeed in offering indexed products that are similar to our licensed products without being required to obtain a license, or in countries that are beyond our and/or our licensors' jurisdictional reach.

**Competition** 

The industry in which we operate is highly competitive and has seen multiple new entrants over time, and we expect competition to continue to intensify and become more global, especially in light of changes in the financial services industry driven by regulatory reforms such as the Dodd-Frank Wall Street Reform and Consumer Protection Act (Dodd-Frank), European Market Infrastructure Regulation (EMIR), EMIR 3.0, Markets in Financial Instruments Directive II (MiFID II), Capital Requirements Directive IV, Market Abuse Regulation, Benchmarks Regulation, Basel III and various other laws and regulations.

Please also refer to the discussion below and in "Item 1A - Risk Factors" beginning on page [16](#i93ed40d324b64de799da10954483467e_31) for a description of competitive risks and uncertainties.

***Competition in our Derivatives Exchange Business***

We believe competition in the derivatives business is based on a number of factors, including, among others:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• brand and reputation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• efficient and secure clearing, settlement and support services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• depth and liquidity of markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• capital and margin efficiencies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• diversity of product offerings and frequency and quality of new product development and innovative services;

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• ability to position and expand upon existing products to address changing market needs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• efficient and seamless customer experience;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• transparency, reliability, anonymity and security in transaction processing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory environment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• connectivity, accessibility, flexibility in execution methods and distribution;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• technological capability and innovation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• overall transaction costs.

We believe we compete favorably with respect to these factors. Our deep, liquid markets; diverse and complementary product offerings; frequency and quality of new product development; and efficient, secure clearing, settlement and support services, distinguish us from others in the industry. We believe that in order to maintain our competitive position, we must continue to expand globally; develop and offer new and innovative products; enhance our technology infrastructure, including its reliability, functionality and security; maintain liquidity and low transaction costs; continue to strengthen our risk management capabilities and solutions; and implement customer protections designed to ensure the integrity of our market and the confidence of our customers.

We compete in a large and expanding financial services trading, clearing and settlement marketplace globally. Our competitors include, among other entities, exchanges such as Intercontinental Exchange, Inc. (ICE), Cboe Global Markets (Cboe), Euronext N.V., the Hong Kong Exchanges and Clearing Limited (HKEX), and Deutsche Börse AG. We also face competition from new entrants into the marketplace, including newly launched FMX Futures Exchange, as well as digital asset platforms and emerging prediction markets. Competition also includes alternative means of developing exposures through alternative instruments (depending on market factors) such as cash, OTC, ETFs, options, warrants, contracts for differences, structured products and other offerings and incorporates large customer and channel internalization of trade flows and data. New emerging competitors have targeted different segments of our industry, with multiple execution models and products, and emerging technologies will continue to offer additional alternative products in the future. Competition in our industry continues to be dynamic, and recent developments and alliances may result in a growing number of well-capitalized trading service providers that compete with all or a portion of our business.

***Competition in our Derivatives Clearing Business***

In recent years there has been increased competition in the provision of clearing services for derivatives, and we expect competition to continue to increase in connection with compliance with Dodd-Frank, EMIR 3.0, Basel III, MiFID II and other various laws and regulations.

Our competitors in the derivatives clearing services space include, among others, companies such as ICE, LCH Group, OCC, Cboe Clear, DTCC, HKEX, Japan Securities Clearing Corporation, LME Clear and Eurex Clearing. Several new derivatives clearing operators have gained approval in the U.S. in the last decade. In light of the implementation of new regulatory requirements and other financial services reforms, we believe other exchanges and infrastructure providers also may undertake to provide clearing and other related post-trade services in the U.S. as CFTC-regulated clearing organizations.

We believe competition in derivatives clearing services is based on, among other things, the value of providing customers with capital and margin efficiencies; quality and reliability of the services; creditworthiness of the clearing house; regulatory costs; timely delivery of the services; reputation; diversity of the service offerings; confidentiality of positions and information security protective measures; and the fees charged for the services provided.

***Competition in our Securities Clearing Business***

We plan to launch our securities clearing business later in 2026 beginning with cash U.S. Treasury and repo transactions. FICC, a subsidiary of DTCC, is the primary player in the U.S. Treasury clearing market with new entrants, including ICE Clear Credit's Treasury Clearing Service. We believe competition in securities clearing will be based upon principles similar to the derivatives clearing business.

***Competition in our Cash Markets Business***

The cash markets businesses face substantial competition across a wide array and growing number of venues. In FX, the marketplace is highly fragmented, and there is competition from other electronic communication networks, single-dealer platforms, bank-owned multi-participant platforms, streaming and request for quote services, trading venues tied to data platforms, voice brokers, other broker enabled platforms and other venues. There is a growing array of platforms and technologies, often owned by well-capitalized financial institutions and intermediaries that are also driving internalization of client FX trade flows. There is also increasing competition from foreign government entities providing financial inducements to establish new FX trading venues in their countries.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

In the fixed income space, there are also multiple providers of U.S. Treasury, European and U.S. repo, and European bond trading, as well as other products such as corporate bonds, municipal bonds, mortgage-backed bonds and agencies, and a multitude of competitors and new entrants offering single-dealer liquidity, bank-owned multi-participant platforms, streaming and request for quote services, and other broker-and exchange-enabled platforms. Internalization is a growing part of the fixed income marketplace as well. We also face competition from parties able to offer both on-the-run and off-the-run marketplaces.

A key strategy of several of these alternative and emerging venues is to compete on price, offering their services at significantly lower rates than the established EBS and BrokerTec platforms. This strategy aims to draw customers away from our markets, thereby shifting market share.

***Competition in our Data Services Business***

Technology companies, market data and information vendors and front-end software vendors also represent actual and potential competitors because they have their own substantial market data calculation and distribution capabilities that could serve as alternative means for receiving open market data feeds instead of connecting directly to our exchanges. Multiple other industry participants offer both referential and indicative pricing alternatives to our offerings, which are widely distributed and available across a variety of media. Distributors and consumers of our market data also may use our market data as an input into products that compete against our traded or cleared products. Although we may receive license fees for such products, such fees may not offset the impact of any loss in revenue from our comparable product.

**Regulatory Matters** 

Our businesses are regulated and serve a customer base that includes regulated market participants, and as such, we are subject to extensive regulation, primarily in the U.S., UK and EU. Developments in the regulatory environment therefore have the potential to significantly affect our businesses.

Please also refer to the discussion below and in "Item 1A - Risk Factors" beginning on page [16](#i93ed40d324b64de799da10954483467e_31) for a description of regulatory and legislative risks and uncertainties.

***Regulation of our Derivatives Business, Derivatives Clearing Business, and Swap Data Repositories***

The operation of our U.S. futures exchanges and our derivatives clearing business are subject to extensive regulation by the CFTC that requires our regulated subsidiaries to satisfy the requirements of certain core principles relating to the operation and oversight of our markets and our clearing house. The CFTC carries out the regulation of the futures and swaps markets and clearing houses in accordance with the provisions of the Commodity Exchange Act (CEA) as amended by, among others, the Commodity Futures Modernization Act and Dodd-Frank.

Regulations implementing Dodd-Frank include rules relating to the implementation of mandatory clearing of certain OTC derivatives, swap reporting, operation of a clearing house, anti-manipulation, large trader reporting, product definitions, the definition of an agricultural commodity and certain provisions of the rules applicable to designated contract markets, swap execution facilities and swap data repositories.

CME has been designated as a systemically important financial market utility and a systemically important derivatives clearing organization. These designations carry with them additional regulatory oversight of certain of our risk-management standards and clearing and settlement activities by the CFTC and the Federal Reserve Board.

In connection with the global offering of our products and clearing services, this business is also subject to the rules and regulations of the local jurisdictions in which we conduct business, including the European Securities and Markets Authority, the UK Financial Conduct Authority (FCA) and Bank of England, the Netherlands Authority for the Financial Markets (AFM) and the Federal Financial Supervisory Authority in Germany, among others.

FanDuel Prediction Markets LLC, which is part of our joint venture with FanDuel, is a registered FCM. As an FCM, it is subject to the CEA and the related CFTC regulations and the applicable rules and provisions of the National Futures Association. It is also subject to our applicable exchange rulebooks.

***Regulation of our Cash Markets Business***

The operation of BrokerTec subjects us to regulation by the Financial Industry Regulatory Authority and the SEC as a broker-dealer and alternative trading system operator. BrokerTec is also subject to regulation in the UK by the FCA, as a multilateral trading facility (MTF), in the EU by the AFM, as a regulated market and by the applicable regulators in Singapore and Canada.

Our EBS business holds various permissions, approvals and exemptions globally, including those that subject certain of its activities to FCA, AFM, Monetary Authority of Singapore, Australian Securities and Investments Commission, Hong Kong Monetary Authority and Canadian oversight.

The settlement of matched principal and exchange-traded businesses requires access to clearing houses either directly or through third-party providers of clearing and settlement services. BrokerTec Americas is a member of the FICC, through which

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

it clears U.S. Treasury and repo products. Our BrokerTec business operated in the EU also connects to LCH Limited, LCH SA, BME Meff Clear and Cassa di Compensazione e Garanzia, which act as central clearing participants in the European and UK gilt repo markets.

***Regulation of our Securities Clearing Business***

Our operation of CMESC subjects us to regulation by the SEC as a securities clearing agency under the Securities Exchange Act and its related rules and regulations.

***Regulation of our Data Services Business***

Our subsidiary, CME Benchmark, is a registered benchmark administrator, authorized and supervised by the FCA under the UK Benchmark Regulations. CME Benchmark administers a variety of different multi-asset class data products, including CME Term SOFR.

***Key Areas of Focus***

We actively monitor and participate in the domestic and international legislative and rulemaking processes for our industry, including providing government testimony, commenting on proposed legislation and rulemaking, and engaging with our regulators and policymakers on potential impacts to the marketplace. We are also focused on impacts from the new U.S. administration and its federal regulatory appointees and any anticipated changes that may result.

Our key areas of focus in the regulatory environment are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The approach to digital assets regulation and market structure legislation, which may affect our existing offerings or our ability to provide future offerings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The outcome of both litigation and regulatory consideration of issues relating to prediction markets, which could impact our existing and future offerings through our joint venture with FanDuel.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The implementation of rules resulting in negative treatment of the liquidity profile of U.S. Treasury securities, including as qualifying liquidity resources, or any potential limitation on the use of U.S. Treasury securities as collateral could result in increased costs to us and our clearing firms.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The implementation of the SEC's mandate for central clearing of U.S. Treasury securities and potential impacts to the industry. We plan to launch clearing services under CMESC later in 2026 to help market participants comply with the mandate for U.S. Treasury transactions (as of December 31, 2026) and repo transactions (as of June 30, 2027).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Basel III Endgame rules. In July 2023, the Federal Reserve Board, Federal Deposit Insurance Corporation, and Office of the Comptroller of the Currency jointly proposed changes to the regulatory capital framework for global systemically important banks, to implement international capital standards issued by the Basel Committee on Banking Supervision, which the Fed Vice Chair said will not be implemented as originally proposed. Thus, CME Group's focus is more broadly on monitoring any new developments and implementations of the framework. The U.S. prudential regulators have proposed rules to implement the final aspects of the Basel III framework that would standardize further aspects of the capital framework, as well as more broadly apply the capital framework to banks with assets greater than $100 billion. Additionally, other areas of the U.S. bank capital framework have come into focus as potential changes to the global systemically important bank capital surcharge calculation worksheet have been introduced, which could increase capital requirements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Financial Stability Board (FSB) consultation proposing that central counterparties (CCPs) maintain separate, dedicated resources and tools for resolution. While the FSB cannot dictate the implementation of its standards, including in the U.S., it has historically exerted pressure on local jurisdictions to adopt its proposals. While the CFTC has not indicated any intention to support such a proposal, if it were supported in the U.S., this proposal could negatively impact cleared markets by increasing costs, reducing participation, and disincentivizing default management participation. The FSB consultation also supports early intervention by resolution authorities which could preempt CCP recovery efforts and the role of the CFTC.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The potential for regulatory or policy actions that could result in changes to market structure for the clearing of derivative transactions, which may impact our business model or the competitive landscape of the industry.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The implementation of a transaction tax or user fee in the U.S., UK or EU, or in the States of Illinois or New Jersey, which could discourage institutions and individuals from using our markets or products or encourage them to trade in another less costly jurisdiction. Legislation to impose a financial transaction tax has been proposed previously in the U.S. Congress, Illinois General Assembly (including a recent such proposal) and the State of New Jersey Legislature. Additionally, from time to time, the proposed U.S. presidential budget request has included a proposal to impose a user fee to fund all or a portion of the budget of the CFTC. Legislation would be necessary to impose such a fee. Federal legislation has previously been proposed by Congress that would impose a user fee on digital asset spot markets to

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

fund CFTC regulation of those assets. Such a user fee, if adopted, could potentially be expanded to apply more broadly to the futures and options markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Legislation that proposes to eliminate the 60/40 tax treatment of certain of our futures and options contracts, which would result in 60% of the gains being taxed at the short-term capital gain rate instead of the long-term capital gain rate. This would impose a significant increase in tax rates applicable to certain market participants and could result in a decrease in their trading activity.

**Human Capital Management** 

We rely on a highly skilled and experienced global workforce to meet our business objectives. As of December 31, 2025, our global employee population consisted of approximately 3,875 employees, with 58% (approximately 2,230) working in the U.S. and the remaining 42% (approximately 1,645) working in our various non-U.S. locations (Australia, Brazil, Canada, China, France, Hong Kong, India, Japan, Mexico, Netherlands, Singapore, South Korea, Switzerland, United Arab Emirates and the UK).

We provide our workforce with a compelling employee experience that allows us to attract and retain industry-leading talent. We are continually seeking new ways to challenge, develop and support our employees. Select highlights of our employee experience include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We offer a wide range of benefits designed to support our employees' health and well-being, retirement needs and work/life balance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our competitive compensation programs align employee rewards with shareholder interests and emphasize our pay-for-performance philosophy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We provide a variety of avenues for employees to grow their expertise, including tuition assistance for continuing education, onsite and virtual-led professional development training courses, access to external seminars and technical skills training and thousands of online educational courses. We also offer an integrated series of customized leadership development programs to prepare employees for each stage of their careers.

We regularly conduct employee engagement surveys to better understand employee perspectives and improve our processes and offerings. Our 2025 engagement survey had a 74% participation rate and an overall engagement score of 82%, indicating employees feel very positively about a number of factors, including learning, collaboration, the future of the company and recognition.We also monitor human capital metrics, such as voluntary turnover, internal placement for open roles and promotions, to understand where further workforce investments may be necessary. During 2025, our performance against these metrics was:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 4.1% voluntary turnover

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 35.9% of open roles filled with internal candidates

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 14.5% of employees promoted

Our Chief Human Resources Officer provides our senior management and Board with regular updates related to our employee experience.

**ITEM 1A.&nbsp;&nbsp;&nbsp;&nbsp;RISK FACTORS**

In addition to the other information contained in this Annual Report on Form 10-K, you should carefully consider the factors discussed below, which are the risks we believe are material at this time. If any of these risks actually occur or continue to occur, our business, financial condition and results of operations could be materially and adversely affected. These risks and uncertainties are not the only ones facing us. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business.

**RISKS RELATING TO OUR INDUSTRY**

***Our business is subject to the impact of global market, economic and political conditions that are beyond our control and that could significantly impact our business and make our financial results more volatile.***

Our revenue is substantially derived from fees for transactions executed and cleared in our markets. The trading volumes in our markets are directly affected by domestic and international factors that are beyond our control, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• economic, political and geopolitical market conditions, including the instability caused by trade policies and wars;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• legislative and regulatory changes, including any direct or indirect restrictions on or increased costs associated with trading in our markets or our clearing services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• broad trends in the industry and financial markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in price levels, trading volumes and volatility in the derivatives, cash and OTC markets and in their underlying markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• shifts in demand or supply in commodities underlying our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• competition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in government monetary policies and the U.S. Federal Reserve and other international banks' forecasted interest rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• availability of capital to our market participants and their appetite for risk-taking;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• levels of assets under our customers' management;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• volatile weather patterns, droughts, natural disasters and other catastrophes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• pandemics affecting our customer base or our ability to operate our markets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidation or expansion in our customer base and within our industry.

Any one or more of these factors may contribute to reduced activity in our markets. Historically, periods of heightened uncertainty have tended to increase our trading volume due to increased hedging activity and the increased need to manage the risks associated with, or speculate on, volatility. However, in the period after a material market disturbance, there may persist extreme uncertainties, which may lead to decreased volume due to factors such as reduced risk exposure, fluctuating interest rates, central bank asset purchase programs and lack of available capital. The shifts in market trading patterns we experienced as a result of the financial crisis of 2008 may or may not recur in the future, and our business will be affected by future economic uncertainties, which may result in decreased trading volume and a more challenging business environment for us. A reduction in overall trading volume or in certain products could render our markets less attractive to market participants as a source of liquidity, which could result in further loss of trading volume and associated transaction-based revenue. Material decreases in trading volume would have a material adverse effect on our financial condition and operating results.

***We operate in a heavily regulated environment that imposes significant costs and competitive burdens on our business, and our failure to maintain compliance with regulations, our status as a regulated entity, or BrokerTec Americas' status as a member in good standing at FICC, could result in the loss of customers, fines or other consequences to our regulated status.***

We are primarily subject to the jurisdiction of the regulatory agencies in the U.S., UK and EU. As a result of our global operations, we are also subject to the rules and regulations of other local jurisdictions in which we conduct business and offer our products and services, as appropriate.

Our businesses and those of many of our clients have been and continue to be subject to extensive legislation and regulatory scrutiny, and we face the risk of continued increasing oversight and changes to our regulatory environment and business in the future and have incurred and expect to continue to incur significant costs to comply. Additional new laws or regulations or changes in enforcement practices applicable to our businesses or those of our clients could be imposed in the U.S. or other jurisdictions, which could change, or require us to change, our business practices or the structure of our business, including its current governance, risk oversight or regulatory structure, or impose significant costs on us by, for example, requiring more of our funds to be set aside for the guaranty fund or to meet other compliance requirements. This could adversely affect our ability to compete effectively with other institutions that are not affected in the same way or impact our clients' overall trading volume and demand for our market data and other services. Additionally, regulations imposed on financial institutions or market participants generally may adversely impact their trading activity in our markets. To the extent the legislative and regulatory environment becomes more onerous for us or less beneficial for us or our customers, our business, financial condition and operating results could be negatively affected.

Legislation may be proposed, both domestically and internationally, that could, for example, add a transaction tax on our products or change the way our market participants are taxed on the products they trade on our markets. If such proposals were to become law, they could have a negative impact on our industry and on us by making transactions more costly to market participants, which may reduce trading and could make our markets less competitive, with a resulting negative impact on our business, financial condition and operating results.

Legislation regarding the regulatory market structure applicable to the trading and clearing of spot digital assets is currently being considered in Congress. It is not yet certain whether the legislation will be signed into law or whether it will have any impact on listed derivatives regulation.

The legal status of certain event-based contracts, most notably those based on sports events, is the subject of litigation in various jurisdictions. The outcome of these cases, new laws or regulations, or changes in the interpretation of existing laws or regulations could immediately or subsequently impact our ability to offer certain event contracts and could subject us to additional litigation or regulatory scrutiny.

If we fail to comply with applicable laws, rules or regulations, we may be subject to censure, fines, cease-and-desist orders, suspension of our business, removal of personnel or other sanctions, including revocation of our designations as a contract market, derivatives clearing organization, swap data repository, broker-dealer, MTF or other regulatory status.

Our broker-dealer and MTF businesses, BrokerTec and EBS, are also extensively regulated in various jurisdictions. These regulatory obligations generally include proper licensing and qualification of the firms and individuals, substantive conduct standards, communication and disclosure rules, monitoring and surveillance, training, capital requirements, supervisory obligations, maintenance of anti-money laundering programs, suspicious activity reporting, risk management standards, trade reporting, and ongoing examinations and reviews. The risks from failing to comply with these regulatory obligations include potential liability and/or disciplinary action against the firm and individuals, monetary penalties and restrictions on future activities.

BrokerTec Americas' matched principal platform facilitates anonymous trading in significant volumes from wholesale market participants, many of which are FICC members and understand that BrokerTec Americas is also a FICC member, such that their trades are expected to be novated promptly to FICC, which will be their ultimate counterparty. A failure of BrokerTec Americas to maintain its membership with FICC could adversely impact the willingness of such participants to continue trading on our platform. As part of maintaining its FICC membership, BrokerTec Americas is required to timely and fully meet all margin calls and other obligations established by FICC, and as such must maintain ready access to sufficient liquidity to satisfy those obligations. BrokerTec Americas maintains access to liquidity resources it believes will satisfy these obligations in normal and stressed circumstances, but there can be no guarantee it will never experience a shortfall.

Please see "Item 1 - Business - Regulatory Matters" beginning on page [12](#i93ed40d324b64de799da10954483467e_25) for additional information on our areas of regulatory focus.

***Some of our clearing house's largest clearing firms have indicated their belief that clearing facilities should not be owned or controlled by exchanges and should be operated as utilities and not for profit. These clearing firms have sought, and may seek in the future, legislative or regulatory changes that would, if adopted, enable them to use alternative clearing services***

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

***for positions established on our exchanges or to freely move open positions among clearing houses in order to take advantage of our liquidity. Even if they are not successful, these factors may cause them to limit the use of our markets.***

Our clearing house seeks to offer customers, intermediaries and clearing firms universal access in order to maximize the efficient use of capital, exercise appropriate oversight of value at risk and maintain operating leverage from clearing activities on our exchanges. Our strategic business plan for our futures and options business is to operate an efficient and transparent vertically-integrated transaction execution, clearing and settlement business. Some of our clearing firms have expressed the view that clearing firms should control the governance of clearing houses or that clearing houses should be operated as utilities rather than as part of for-profit enterprises. Some of these firms, along with certain industry associations, have sought, and may seek in the future, legislative or regulatory changes to be adopted that would facilitate mechanisms or policies that allow market participants to transfer positions of futures or options from an exchange-owned clearing house to a clearing house owned and controlled by clearing firms. If these legislative or regulatory changes are adopted, our business, financial condition and operating results could be adversely affected.

***We face intense competition from other companies. If we are not able to successfully compete, our business, financial condition and operating results will be materially harmed.***

Our industry is highly competitive, and we expect competition to continue to intensify. We encounter competition in all aspects of our business, including from entities having substantially greater capital and resources, offering a wide range of products and services and in some cases operating under a different and possibly less stringent regulatory regime. We face competition from other futures, securities and securities option exchanges; OTC markets; clearing organizations; consortia formed by our members and large industry participants; alternative trade execution facilities and crypto and prediction market platforms; technology firms, including market data distributors and electronic trading system developers; and others. Our competitors and potential competitors may have greater financial, marketing, technological and personnel resources than we do.

Our competitors may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• respond more quickly to competitive pressures and opportunities, including responses based upon their corporate governance structures, which may be more flexible and efficient than our corporate governance structure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop products that are preferred by our customers compared to those offered by CME Group;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop risk transfer products that compete with our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• price their products and services more competitively;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop and expand their network infrastructure and service offerings more efficiently;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• utilize better, more user-friendly or more reliable technology, including artificial intelligence;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• take greater advantage of acquisitions, alliances and other opportunities that provide a competitive advantage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• more effectively market, promote and sell their products and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• market and sell their services more effectively because of their existing customer and alliance partner relationships, as well as their recognized brand names; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• exploit regulatory disparities between traditional, regulated exchanges and alternative markets that benefit from a reduced regulatory burden and lower-cost business model.

If our products, markets and clearing services are not competitive or are viewed as less competitive, our business, financial condition and operating results could be adversely affected. A decline in our fees or loss of customers could lower our revenues, which would adversely affect our profitability.

Please see "Item 1 - Business - Competition" beginning on page [10](#i93ed40d324b64de799da10954483467e_22) for additional information on the competitive environment and its potential impact on our business.

***Our trading volume, and consequently our revenues and profits, would be adversely affected if we are unable to retain our current customers at substantially similar trading levels or attract new customers.***

The success of our business depends, in part, on our ability to maintain and increase trading volume in our markets. To do so, we must maintain and expand our product offerings, our customer base and our trade execution facilities, our pre- and post-trade services and clearing facilities. Our success also depends on our ability to offer competitive prices and services in an increasingly price-sensitive business. For example, some of our competitors have engaged in aggressive pricing strategies in the past, such as lowering the fees they charge for taking liquidity and increasing liquidity payments or rebates. We cannot provide assurances that we will be able to continue to expand our products and services, that we will be able to retain our current customers or attract new customers or that we will not be required to modify our pricing structure to compete effectively. Changes in our pricing structure may result in a decrease to our profit margin.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

Our clearing firms must meet certain capital requirements and must deposit collateral to meet performance bond and guaranty fund requirements. There is no guarantee the collateral deposited will continue to maintain its value. To the extent a clearing firm were to experience a decrease in capital and be unable to meet requirements, it may be required to decrease its trading activity.

Additionally, from time to time, certain customers may represent a significant portion of the open interest in our individual product lines or contracts, and a substantial decrease in their trading activity could have a negative impact on the liquidity of the particular product line or contract.

If we fail to maintain trading volume, as a result of a loss of customers or decrease in trading activity; expand our product offerings or execution facilities; or are unable to attract new customers, our business and revenues will be adversely affected. Declines in trading volume may also negatively impact market liquidity, which could lead to further loss of trading volume. Because our cost structure is largely fixed, if demand for our products and services and our resulting revenues decline, we may not be able to adjust our cost structure on a timely basis, and our profitability could be adversely affected.

***Our role in the global marketplace places us at greater risk than other public companies for a cyber attack and other cyber-security risks. Our technology, our customers, our people and our third-party service providers are vulnerable to cyber-security threats, which could result in wrongful use of our data or our customers' data or cause interruptions in our operations, our customers' operations, or our third-party service providers' operations, which could cause us to lose customers and trading volume and result in substantial liabilities. We also could be required to incur significant expense to protect or remediate damage to our systems and/or investigate any alleged attack.***

We regard the secure storage and transmission of data and the ability to continuously transact and clear on our electronic trading platforms as critical elements of our operations and our operational resiliency. Our technology, our customers, our people and our third-party service providers are vulnerable to targeted attacks, such as "phishing" attacks, unauthorized access, fraud, business email compromise, computer viruses, denial of service attacks, terrorism, "ransomware" attacks, attacks created through artificial intelligence, firewall or encryption failures or other security or operational risks. Criminal groups, political activist groups and nation-state actors have targeted the financial services industry in general, including as a result of armed conflicts, and our role in the global marketplace places us at significant risk for a cyber attack and other information security threats. While to date we have not experienced cyber incidents that are individually, or in the aggregate, material, we and certain of our third-party service providers have experienced cyber attacks of varying degrees in the past.

Our usage of mobile, web, and cloud technologies, such as those pursuant to our partnership with Google Cloud, may increase our risk of a cyber attack. Our security defenses may also be impacted or breached due to employee error, malfeasance, system errors or vulnerabilities. Additionally, outside parties may attempt to fraudulently induce employees, users, customers or our third-party service providers to disclose sensitive information in order to gain access to our technology systems and data, or our customers' systems and data, or our third parties' systems and data. Any such breach or unauthorized access could result in significant legal and financial exposure, damage to our reputation, and a loss of confidence in the services we provide that could potentially have an adverse effect on our business, while resulting in regulatory penalties or the imposition of additional obligations by regulators or others. The regulatory environment related to information security, privacy, data collection, data usage and use of artificial intelligence is increasingly rigorous and complex, and any failure to comply may carry significant penalties and reputational damage.

We have designed our cyber defense program to mitigate such attacks and security risks through administrative, physical and technical safeguards. As part of our global information security (GIS) and privacy programs, we employ resources to prevent, detect and respond to cyber attacks and security risks that could impact our people, processes and technology infrastructure, including rapid response to zero-day vulnerabilities. However, our security measures or those of our third-party service providers, including any cloud-based technologies, may prove insufficient depending upon the attack or threat posed. It is impossible to precisely predict the likelihood or impact of any cyberattack on our industry generally, or on our business. Any security attack or breach could result in system failures and delays, malfunctions in our operations, loss of customers or lower trading volume, loss of competitive position, damage to our reputation, disruption of our business, legal liability or regulatory fines and significant costs, which in turn may cause our revenues and earnings to decline and could have a material impact on our financial condition or results of operations. We may be subject to litigation and financial losses that exceed our insurance policy limits or are not covered under any of our current policies.

***As a financial services provider, we are subject to significant litigation risk and regulatory liability and penalties.***

Many aspects of our business present substantial litigation risks. These risks include, among others, potential liability from disputes over terms of a trade, the claim that a system failure or delay caused monetary losses to a customer, that we entered into an unauthorized transaction, that we provided materially false or misleading statements in connection with a transaction or that we failed to effectively fulfill our regulatory oversight responsibilities. We may be subject to disputes regarding the quality of trade execution, the settlement of trades or other matters relating to our services. We may become subject to these claims as a

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

result of failures or malfunctions of our systems and services we provide. We could incur significant legal expenses defending claims, even those without merit. In addition, an adverse resolution of any future lawsuit or claim against us could have a material adverse effect on our business and our reputation. To the extent we are found to have failed to fulfill our regulatory obligations, we could lose our authorizations or licenses or become subject to conditions that could make future operations more costly and impair our profitability. Such events could also result in customer dissatisfaction and a decline in their willingness to trade on our markets.

***We may be at greater risk from terrorism, which poses physical security risks and cybersecurity risks, than other companies.***

Given our role in the global financial services industry, we may be more likely than other companies to be a direct target of, or an indirect casualty of, attacks by terrorists or terrorist organizations. It is impossible to accurately predict the likelihood or impact of any terrorist attack against us or our third-party service providers, or on our industry generally. While we have implemented significant physical security protection measures, business continuity plans, and established backup sites to provide operational resiliency, in the event of an attack or a threat of an attack, these security measures and contingency plans may be inadequate to prevent significant disruptions in our business, technology or access to the infrastructure necessary to maintain our business. Such an attack may result in harm to our personnel or the closure of our facilities or render our backup data and recovery systems inoperable, or have similar consequences for our third-party service providers. Damage to our facilities due to terrorist attacks may be significantly in excess of any amount of insurance coverage available, or we may not be able to insure against such damage at a reasonable price or at all. The threat of terrorist attacks also may negatively affect our ability to attract and retain employees. Any of these events could have a material adverse effect on our business, financial condition, and operating results.

**RISKS RELATING TO OUR BUSINESS** 

***Damage to our reputation or brand could harm our business.***

Maintaining our reputation and brand is critical to attracting and retaining customers, investors and employees and to maintaining our relationships with our regulators and other government officials. Negative publicity regarding our company or actual, alleged or perceived issues regarding our company, products or services, including social and environmental concerns relating to our company or certain commodity products and increased impact from climate change or criticism or market reaction to the performance of our market in periods of extreme volatility, could give rise to reputational risk, which could significantly harm our business prospects. These issues may include, but are not limited to, any of the risks discussed in this Item 1A, including risks from customer disputes, system failures or intrusions, cybersecurity attacks, failures to meet our regulatory obligations, failures of a clearing firm or other counterparty, issues relating to our third-party service providers, alleged or actual fraud or misconduct or manipulative activity, or ineffective risk management.

***The success of our markets depends on our ability to complete development of, successfully implement and maintain electronic trading and clearing systems that have the functionality, performance, availability, resilience, capacity, security and speed required by our customers.***

The success of our business depends in large part on our ability to create interactive electronic marketplaces for a wide range of products that have the required functionality, performance, availability, resilience, capacity, security and speed to attract and retain customers. In 2025, 93% of our overall contract volume was generated through electronic trading on our CME Globex &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;electronic platform.

We must continue to enhance our electronic trading platforms and other technology offerings to remain competitive. As a result, we will continue to be subject to risks, expenses and uncertainties encountered in the rapidly evolving market for electronic transaction services. These risks include our failure or inability to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• provide reliable and cost-effective services to our customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop, in a timely manner, the required functionality to support electronic trading in a manner that is competitive with the functionality supported by other electronic markets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• maintain the competitiveness of our fee structure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• attract ISVs to write software that will allow our customers to effectively access our systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• respond to technological developments or service offerings by competitors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• generate sufficient revenue to justify the substantial capital investment we have made and will continue to make to enhance our electronic trading platforms and other technology offerings.

Failure to continuously improve our electronic trading systems and technology offerings could materially impact our financial condition or results of operations. This includes, but is not limited to, the successful development and migration of our markets and supporting operational and business functions to the Google Cloud in the new private Google Cloud region. If our trading systems and technology offerings cannot be developed to include other products and markets, or if they lack the functionality,

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

performance, availability, resilience, capacity, security, and speed demanded by our customers, our ability to successfully compete, along with our revenues and profits, will be adversely affected.

Additionally, we rely on our customers' ability to have the necessary back office functionality to support our new products and our trading and clearing functionality, including generating sufficient liquidity. To the extent our customers and/or their third-party service providers are not prepared and/or lack the resources or infrastructure, the success of our new initiatives may be compromised.

***Our business is subject to the impact of financial markets volatility, which is caused by conditions that are beyond our control.***

Trading volume in our markets and products is largely driven by the degree of volatility - the magnitude and frequency of fluctuations - in prices and levels of the underlying commodities, securities, indices, financial benchmarks or other instruments. Volatility increases the need to hedge price risk and creates opportunities for investment and speculative or arbitrage trading. Were there to be a sustained period of stability in the prices or levels of the underlying commodities, securities, indices, benchmarks or other instruments of our products, we could experience lower trading volumes, slower growth or declines in revenues.

Because our cost structure is largely fixed, if demand for our current products and services declines for any reason, we may not be able to adjust our cost structure to counteract the associated decline in revenues, which would cause our net income to decline.

***If we experience system failures or capacity constraints, our ability to conduct our operations and execute our business strategy could be materially harmed, and we could be subject to significant costs and liabilities.***

Our business is highly dependent on our ability to process, execute and monitor, in an efficient and uninterrupted manner, a large number of transactions, which occur at high volumes and frequencies across multiple systems and our ability to access key business data, financial information, order processing and invoicing. We are heavily reliant on the capacity, reliability and security of our information technology and communications and other business systems and software supporting our operations provided by third parties. Our systems, or those of our third-party service providers, including data center and cloud providers, may fail or be shut down or, due to capacity constraints, may operate slowly, causing one or more of the following to occur:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• unanticipated disruptions in service to our customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• slower response times and delays in our customers' trade execution and processing;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• failed settlement of trades;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• incomplete or inaccurate accounting, recording, or processing of trades;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• financial losses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• cybersecurity attacks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• litigation or other customer claims;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• loss of customers; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• regulatory sanctions.

We cannot assure that we will not experience system failures from power or telecommunications failures, acts of God, war or terrorism, human error on our part or on the part of our third-party service providers or partners, natural disasters, fire, rising temperatures, sabotage, hardware or software malfunctions or defects, computer viruses, cyber attacks, acts of vandalism or similar occurrences. If any of our systems or the systems of our third-party service providers do not operate properly, are compromised or are disabled, including as a result of system failure, employee or customer error or misuse of our systems, we could suffer financial loss, liability to customers, regulatory intervention or reputational damage that could affect demand by current and potential users of our market. On November 27, 2025, our largest data center owned and operated by CyrusOne experienced a critical cooling failure caused by human error. In response to the critical cooling failure, we made the decision to temporarily halt our markets. Our markets opened the following day on a delayed basis. Although the impact to our business from the event was limited and not material, we cannot make assurances that we will not experience future events that may be material.

From time to time, we have experienced system errors and failures that have resulted in some customers being unable to connect to our electronic trading platforms and technology offerings, or that resulted in erroneous reporting. Such errors may result in CME Group being liable or in our voluntary assumption of financial liability. We cannot assure that if we experience system errors or failures in the future that they will not have a material adverse impact on our business. Any such system failures that cause an interruption in service or decrease our responsiveness could impact our trading volumes, impair our reputation, damage our brand, result in regulatory fines and/or have a material adverse effect on our business, financial condition and operating results.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

Regulations relating to our trading and clearing systems generally require the handling of anticipated present and future peak trading volume. Heavy use of our systems during peak trading times or at times of unusual market volatility could exceed our available capacity based on estimated future trading volumes and cause them to operate slowly or even to fail for periods of time. We constantly monitor system loads and performance, and regularly implement system upgrades to handle estimated increases in volume. However, we cannot assure that our estimates of future trading volume and order messaging traffic will be accurate or that our systems will always be able to accommodate actual trading volume and order messaging traffic without failure or degradation of performance or speed. Increased trading volume and order messaging traffic may result in connectivity problems or erroneous reports that may affect users of our platforms. System failure or degradation could lead our customers to file formal complaints with industry regulatory organizations, to file lawsuits against us or to cease doing business with us or could lead our regulators to initiate inquiries or proceedings for failure to comply with applicable laws and regulations.

We will need to continue to upgrade, expand and increase the capacity of our systems as our business grows and as we execute our business strategy. Although many of our systems are designed to accommodate additional volume and products and services without redesign or replacement, we will need to continue to make significant investments to accommodate the increases in volume of transactions and order transaction traffic and to provide processing services to third parties. If we cannot increase the capacity and capabilities of our systems to accommodate an increasing volume of transactions and to execute our business strategy, our ability to maintain or expand our businesses could be adversely affected.

***We, as well as many of our customers, depend on third-party service providers for a number of services that are important. An interruption or cessation of an important supply or service by any third party could have a material adverse effect on our business, including revenues derived from our customers' trading activity.***

We depend on a number of suppliers, such as banking, clearing and settlement organizations, telephone companies, internet service providers, data processors, cloud hosting providers, data center providers, and software and hardware vendors, for elements of our trading, clearing, and other systems, as well as communications and networking equipment, computer hardware and software and related support and maintenance. Although we conduct due diligence and monitor important suppliers and service providers (including the resiliency of their operations), we cannot provide assurances of their performance and any interruption or cessation of their supplies or services could negatively impact our operations or those of our customers, as well as affect our reputation, financial or regulatory posture. As discussed above in "If we experience system failures or capacity constraints, our ability to conduct our operations and execute our business strategy could be materially harmed, and we could be subject to significant costs and liabilities," in November 2025, CyrusOne, the owner and operator of our largest data center, experienced a critical cooling failure, which resulted in our decision to temporarily halt our markets.

Many of our customers rely on third parties, such as ISVs, to provide them with front-end systems to access our trading platforms and other back office systems for their trade processing and risk management needs. While these service providers have undertaken to keep current and certify as to our enhancements and make corresponding changes to their software for our interfaces and functionality, we cannot guarantee that they will continue to make the necessary monetary, resource and time investments to keep up with our enhancements and changes.

To the extent any of our service providers or the organizations that provide services to our customers in connection with their trading activities cease to provide these services or cease to provide these services in an efficient, cost-effective manner, or fail to adequately expand their services to meet our needs and the needs of our customers, we could experience decreased trading volume, lower revenues and higher costs. In addition, while we may be entitled to recovery for breaches of, or liabilities otherwise incurred in connection with, our agreements with third-party service providers, such recovery is limited by the terms of these agreements and may not compensate us in full.

***Our business exposes us to substantial credit risk of our clearing firms and other counterparties and, consequently, a decrease in their financial resources could adversely affect us.***

Our clearing house operations expose us to counterparties with differing risk profiles. In our derivatives business, we routinely guarantee transactions submitted by our clearing firm customers with counterparties in the financial industry, including brokers and dealers, commercial banks, investment banks, mutual and hedge funds and other institutional customers. We could be adversely impacted by the financial distress or failure of one or more of our derivatives clearing firms. During 2025, the clearing house transferred an average of approximately $6.7 billion a day through the clearing system for settlement from clearing firms whose positions had lost value to clearing firms whose positions had gained value. Additionally, we are exposed to the risk of loss from the failure of a matched principal counterparty to settle its trades at BrokerTec Americas.

A substantial part of our working capital may be at risk if a clearing firm defaults on its obligations to our clearing house and its margin and guaranty fund deposits are insufficient to meet its obligations. Additionally, BrokerTec Americas is exposed to the potential risk of loss in the event a counterparty fails to meet its obligations. Later in 2026, we expect to launch clearing services for U.S. Treasury cash and repo transactions. While we have a long history in, and deep understanding of, risk

management from the operation of our derivatives clearing house, the operation of a securities clearing house is new to our business.

Our policies and procedures which are designed to ensure that our clearing firms and other counterparties can satisfy their obligations, including collecting margin and guaranty fund contributions from clearing firms, may not succeed in detecting problems or preventing defaults. The processes for calculating and setting margins and financial safeguards is complex and there is no guarantee that our risk models that are utilized to calculate margin and our financial safeguard procedures will adequately protect us in all circumstances. We have in place various measures intended to enable us to cure any default and maintain liquidity. However, we cannot guarantee that these measures will be sufficient to protect market participants from a default or that we will not be adversely affected in the event of a significant default.

In addition, we have established a fund (currently $98.0 million) to provide payments, up to certain maximum levels, to qualified family farmers, ranchers and other agricultural industry participants who use our derivatives products and who suffer losses to their segregated account balances if their clearing firm becomes insolvent.

***Our market data revenues may be reduced by decreased demand, poor overall economic conditions, regulatory changes or a significant change in how market participants trade and use market data.***

We offer a wide range of data services designed to support the trading, risk management, investment and business needs of our customers. Revenues from our market data and information services represented 12% of our total revenues during the years ended December 31, 2025 and December 31, 2024. Factors that may affect our performance and demand for our data include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to maintain existing customers utilizing our data and to attract new customers with our products and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A challenging business environment for our customers, which may require them to reduce their usage of our market data;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The impacts of new regulations, laws, rules or other government policies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to ensure that customers are appropriately licensed and are paying fees for the data used;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The protection of our intellectual property rights and identification of misappropriation and/or misuses of CME Group market data, including through the use of artificial intelligence; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to keep pace with technological developments and client preferences.

***We may have difficulty executing our growth strategy and maintaining our growth effectively.***

We continue to execute on strategic initiatives to grow our business, including efforts to serve the OTC markets and to distribute our products and services on a global basis, and other initiatives to enter new markets. There is no guarantee that our efforts will be successful. Continued growth will require additional investment in personnel, facilities, information technology infrastructure and financial and management systems and controls, and may place a significant strain on our management and resources. For example, if we encounter limited resources, we may be required to increase our expenses to obtain the necessary resources, defer existing initiatives or not pursue certain opportunities. We may not be successful in implementing all of the processes that are necessary to support our growth organically or, as described below, through acquisitions, other investments or strategic alliances and partnerships. Our growth strategy also may subject us to increased legal, compliance and regulatory obligations. Unless our growth results in an increase in revenues that is proportionate to the increase in our costs associated with our growth, our future profitability could be adversely affected, and we may have to incur significant expenditures to address the additional operational and control requirements as a result of our growth.

***We intend to continue to explore acquisitions, other investments and strategic alliances. We may not be successful in identifying opportunities or in integrating the acquired businesses. Any such transaction may not produce the results we anticipate, which could adversely affect our business and our stock price.***

We intend to continue to explore and pursue acquisitions and other strategic opportunities to strengthen our business and grow our company. We may make acquisitions or investments or enter into strategic partnerships, joint ventures and other alliances. The market for such transactions is highly competitive, especially in light of historical merger and acquisition activity in our industry. As a result, we may be unable to identify strategic opportunities or we may be unable to negotiate or finance future transactions on terms favorable to us, which could impact our ability to identify growth opportunities. We may issue additional equity and/or debt as part of strategic partnerships with third parties, as was the case in connection with our partnership with Google Cloud. The issuance of additional equity in connection with any future transaction could be substantially dilutive to our existing shareholders. The issuance of additional debt could increase our leverage substantially.

To the extent we acquire a new business, the process of integration also may produce unforeseen regulatory and operating difficulties and expenditures and may divert the attention of management from the ongoing operation of our business. To the

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

extent we enter into joint ventures and alliances, we may experience difficulties in the development and expansion of the business of any newly formed ventures, in the exercise of influence over the activities of any ventures in which we do not have a controlling interest, as well as encounter potential conflicts with our joint venture or alliance partners. We may not realize the anticipated growth and other benefits from our growth initiatives and investments, which may have an adverse impact on our financial condition and operating results. We also may be required to take an impairment charge in our financial statements relating to our acquisitions and/or investments, which could negatively affect our stock price.

***The expansion of our global operations is complex and subjects us to increased business and economic risks that could adversely affect our financial results.***

In connection with our expanded global operations, we face certain risks inherent in doing business internationally. These risks include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in currency exchange rates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• complying with extensive and complex compliance requirements, regulations and oversight by regulators other than our primary functional regulators;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• difficulties in staffing and associated costs in managing multiple international locations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general economic, social and political conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• protectionist laws and business practices that favor local businesses in some countries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced protection for intellectual property rights in some countries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• language and cultural differences; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• potentially adverse tax consequences.

If we are unable to manage the complexity of our global operations successfully, or if the risks above become substantial for us, our financial performance and operating results could suffer. Further, any measures we may implement to reduce risks of our international operations may not be effective, may increase our expenses and may require significant management time and effort.

As our consolidated financial statements are presented in U.S. dollars, we must translate our foreign subsidiaries' financial statements from local currencies into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, any increases or decreases in the value of the U.S. dollar against the other currencies may affect our operating income and the value of balance sheet items denominated in foreign currencies.

***Our risk management, compliance and monitoring programs might not be effective and may result in outcomes that could adversely affect our reputation, financial condition and operating results.***

In the normal course of our business, we discuss matters with our regulators, including during supervisory engagements and regulatory examinations, and we are subject to their inquiry and oversight. Our regulators have broad enforcement and supervisory powers, including, for example, the power to censure, fine, issue cease-and-desist orders, prohibit us from engaging in some of our businesses or suspend or revoke our regulatory designations or the registration of our officers or employees who violate applicable laws or regulations. Our ability to manage our risks and comply with applicable laws and regulations in the jurisdictions where we operate is largely dependent on our establishment and maintenance of effective risk management, compliance and monitoring programs. In the case of alleged non-compliance with applicable laws or regulations, we could be subject to investigations and judicial or administrative proceedings that may result in substantial penalties or civil lawsuits, including by customers, for damages, which could be significant. Any of these outcomes may adversely affect our reputation, regulatory standing, financial condition and operating results. In extreme cases, these outcomes could adversely affect our ability to conduct our business.

We maintain risk management, compliance and monitoring policies, procedures and programs that are designed to prevent, detect, deter, monitor and manage our risks, including enterprise risk, compliance and internal audit programs, but such policies, procedures and programs may not be fully effective in their design or operation. Some of our risk management processes depend upon evaluation of information regarding markets, customers, employees, third parties or other matters or potential threats that are publicly available or otherwise accessible by us. That information may not in all cases be accurate, complete, up-to-date or properly evaluated. Management of operational, financial, legal and compliance, regulatory, reputational and strategic risk requires, among other things, policies and procedures to record properly and verify a large number of transactions and events. We cannot guarantee that our policies and procedures will always be effective or that we will always be successful in evaluating, monitoring or managing the risks to which we are or may be exposed.

***We could be harmed by misconduct or errors that are difficult to detect and deter.***

There continues to be highly publicized cases involving fraud or other misconduct or manipulative activity by employees of financial services firms and other market participants. Improper trading activity on our platforms by participants could include activities such as spoofing, layering, wash trading and manipulation. Misconduct by our employees and agents could include hiding unauthorized activities from us, improper or unauthorized activities on behalf of customers or the company, improper securities trading activities, circumvention of controls and procedures, improper use of assets, improper use and unauthorized disclosure of data or confidential information of the company or its customers or third parties, improper use of artificial intelligence or failure to provide effective oversight over artificial intelligence, among other potential misconduct.

It is not always possible to deter misconduct, and the precautions we take to prevent and detect this activity, including our internal controls, may not be effective in all cases. Additionally, the emergence of increasingly sophisticated and widely accessible generative artificial intelligence and its ability to create believable yet fabricated content may elevate our risk and susceptibility to fraudulent activities which could result in the wrongful transferring of funds, divulging of sensitive information or other unintended consequences. If we were found to have not met our regulatory oversight and compliance obligations, we could be subject to regulatory sanctions, enforcement actions, financial penalties and restrictions on our activities for failure to properly identify, monitor and respond to potentially problematic activity, and such outcomes could seriously harm our reputation. Our employees and agents also may commit errors that could subject us to financial claims for negligence, as well as regulatory actions, or result in our voluntary assumption of financial liability. Further, allegations by regulatory or criminal authorities of improper trading activities in our markets could affect our brand and reputation and reduce the number of participants trading in our markets. If that should occur, we could face a corresponding decline in trading volume and revenue.

***Intellectual property rights licensed from third-party price reporting agencies form the basis for many of our products from which we derive a significant portion of our volume and revenue. Material changes in the intellectual property landscape or regulatory framework pertaining to such benchmarks could have a negative impact on our ability to offer such products.***

A significant percentage of our contract volume and revenue is based on indexes derived from third-party price reporting agencies. If such third parties take actions that result in the loss of protection for those intellectual property rights or changes in intellectual property laws yield that result, it could have a negative impact on our contract volume and revenues.

***A failure to protect our intellectual property rights, or allegations that we have infringed the intellectual property rights of others, could adversely affect our business.***

Our business is dependent on proprietary technology and intellectual property that we own or license from third parties. We own the rights to a large number of trademarks, service marks, domain names and trade names in the U.S., Europe, and other parts of the world. We have registered many of our most important trademarks in the U.S. and other countries. We hold the rights to a number of patents and have patent applications pending. Our patents cover match engine, trader user interface, trading floor support, market data, general technology and clearing house functionalities. We attempt to protect our proprietary technology and intellectual property rights by relying on patents, trademarks, copyright, database rights, trade secrets, restrictions on disclosure, and other methods. Notwithstanding the precautions we take to protect our proprietary technology and intellectual property rights, it is possible that employees or third parties may copy, misappropriate, or otherwise obtain and use our proprietary technology without authorization or otherwise infringe on our rights. The use of certain artificial intelligence technology can give rise to intellectual property risks, including claims that the data used to train, or in connection with certain models infringes the intellectual property rights of the owner of such data. In addition, in the future, we may have to rely on litigation to enforce our intellectual property rights, protect our trade secrets, challenge the validity and scope of the proprietary rights of others or defend against claims of infringement or invalidity. Any such litigation, whether successful or unsuccessful, could result in substantial costs to us and diversions of our resources, either of which could adversely affect our business.

Patents of third parties may have an important bearing on our ability to offer certain products and services. Our competitors as well as other companies and individuals may obtain, and may be expected to obtain in the future, patents related to the types of products and services we offer or plan to offer. We cannot guarantee that we are or will be aware of all patents containing claims that may pose a risk of infringement by our products and services. In addition, some patent applications in the U.S. are confidential until a patent is issued and, therefore, we cannot evaluate the extent to which our products and services may be covered or asserted to be covered by claims contained in pending patent applications. These claims of infringement are not uncommon in our industry. As a result, we may face allegations that we have infringed the intellectual property rights of third parties, which may be costly for us to defend. If one or more of our products or services is found to infringe on patents held by others, we may be required to stop developing or marketing the products or services, to obtain licenses to develop and market the services from the holders of the patents or to redesign the products or services in such a way as to avoid infringing on the patents. We could also be required to pay damages if we were found to infringe patents held by others, which could materially adversely affect our business, financial condition and operating results. We cannot assess the extent to which we may be required in the future to obtain licenses with respect to patents held by others, whether such licenses would be available or, if

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

available, whether we would be able to obtain such licenses on commercially reasonable terms. If we were unable to obtain such licenses, we may not be able to redesign our products or services at a reasonable cost to avoid infringement, which could materially adversely affect our business, financial condition and operating results.

***Our use of artificial intelligence in our business may be unsuccessful and may give rise to various risks, which could adversely affect our business, reputation or operating results.***

Our financial performance depends, in part, on our ability to develop and market new and innovative services that differentiate our products or provide cost efficiencies, while avoiding increased related expenses. As artificial intelligence is a new and evolving technology in the early stages of commercial use, there are significant risks involved in the development and deployment of artificial intelligence. Moreover, there can be no assurance that our use of artificial intelligence in our business processes, system development, operations, or as part of our product and service offerings will enhance our products or services or augment our business or operating results. Market acceptance of artificial intelligence technologies is uncertain, and we may be unsuccessful in our product development efforts. Our artificial intelligence-related product initiatives and offerings, or use in our internal business operations, may give rise to risks related to accuracy, bias, discrimination, intellectual property infringement, misappropriation or leakage of intellectual property, defamation, data privacy and cybersecurity, among others. We are also exposed to risks related to the use of artificial intelligence technologies by third-party service providers, clients and other financial intermediaries. Risks related to our development and use of artificial intelligence include the possibility of new or enhanced laws or regulations or novel enforcement of existing laws related to artificial intelligence, compliance with which may be costly and burdensome or involve changes to our business practices or products, litigation or other legal liability, or additional oversight, audits or enforcement under existing laws or regulations. Our use of artificial intelligence may also give rise to ethical concerns or negative public perceptions, which may cause brand or reputational harm. Additionally, our existing competitors or new entrants may be developing their own artificial intelligence products and technologies, which may be superior in features or functionality, or cost, to our offerings. Any of these factors could adversely affect our business, reputation or operating results.

**RISKS RELATING TO AN INVESTMENT IN OUR CLASS A COMMON STOCK** 

***Our indebtedness could adversely affect our financial condition and operations and prevent us from fulfilling our debt service obligations. We might still be able to incur more debt, intensifying these risks.***

As of December 31, 2025, we had approximately $3.4 billion of total indebtedness and we had excess borrowing capacity for general corporate purposes under our existing facilities of approximately $2.3 billion.

Our indebtedness could have important consequences. For example, our indebtedness may:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• require us to dedicate a significant portion of our cash flow from operations to payments on our debt, thereby reducing the availability of cash flows to fund capital expenditures, to pursue acquisitions or investments, to pay dividends and for general corporate purposes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increase our vulnerability to general adverse economic conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit our flexibility in planning for, or reacting to, changes in or challenges relating to our business and industry; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• place us at a competitive disadvantage against any less leveraged competitors.

The occurrence of any one of these events could have a material adverse effect on our business, financial condition, results of operations, prospects and ability to satisfy our debt service obligations. In addition, the agreements governing our outstanding indebtedness do not significantly limit our ability to incur additional indebtedness, which, particularly given changes in interest rates, could increase the risks described above to the extent that we incur additional debt. Our regulated businesses are also required to maintain minimum capital requirements set by their applicable regulators.

Please see "Item 7 - Management's Discussion and Analysis of Financial Condition and Results of Operations — Regulatory Requirements" beginning on page [47](#i93ed40d324b64de799da10954483467e_103) for additional information regarding capital requirements.

***Any reduction in our credit rating could increase the cost of our funding from the capital markets.***

Our long-term debt is currently rated investment grade by two of the major rating agencies. These rating agencies regularly evaluate us. Their ratings of our long-term debt are based on a number of factors, including our financial strength, as well as factors not entirely within our control, such as conditions affecting the financial services industry generally. As a result, there can be no assurance that we will maintain our current ratings. In the past, we have experienced ratings downgrades. Our failure to maintain our ratings could adversely affect the cost and other terms upon which we are able to obtain funding and increase our cost of capital. Additionally, if our ratings are downgraded below investment grade due to a change of control, we are required to make an offer to repurchase all of our fixed-rate notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest.

***Our average rate per contract for our derivatives business is subject to fluctuation due to a number of factors. As a result, our average rate per contract in any particular period may not be a reliable indication of our future average rate per contract.***

Our average rate per contract for our derivatives business, which impacts our operating results, is subject to fluctuation due to shifts in the mix of products traded, the trading venue and the mix of customers (whether the customer receives member or non-member fees or participates in one of our various incentive programs) and the impact of our tiered pricing structure. In addition, our members and participants in our various incentive programs generally are charged lower fees than our non-member customers. Variation in each of these factors is difficult to predict and will have an impact on our average rate per contract in the particular period. Because of this fluctuation, we cannot assure that our average rate per contract in any particular period serves as an indication of our future average rate per contract. If we fail to meet securities analysts' expectations regarding our operating results, the price of our Class A common stock could decline substantially.

***Nine of our board members own trading rights, or are officers or directors of firms that own trading rights, on our derivatives exchanges. As members, these individuals may have interests that differ from or conflict with those of shareholders who are not also members. Our dependence on the trading and clearing activities of our exchange members, combined with the CME members' rights to elect six directors, may enable them to exert influence over the operation of our business.***

Nine of our directors own, or are officers or directors of firms that own trading rights on our exchanges. We are dependent on the revenues from the trading and clearing activities of our exchange members. In 2025, 85% of our derivatives contract volume was derived from our members. This dependence may give them influence over how we operate our business.

Many of our members and clearing firms derive a substantial portion of their income and profit from their trading or clearing activities on or through our exchanges. In addition, trading rights on our exchanges have substantial independent value. The amount of profit that members derive from their trading, brokering and clearing activities and the value of their trading rights are, in part, dependent on the fees they are charged to trade, broker, clear and access our markets, and the rules and structure of our markets. As a result, members may not have the same economic interests as holders of our Class A common stock. In addition, our members may have differing interests among themselves depending on the roles they serve in our markets, their methods of trading and the products they trade. Consequently, members may advocate that we enhance and protect their clearing and trading opportunities and the value of their trading privileges over their investment in our Class A common stock, if any.

***Our members have been granted special rights, which protect their trading privileges and require that we maintain open outcry for options products still meeting certain volume thresholds and, in the case of our Class B shareholders, provide them with special board representation.***

Under the terms of the organizational documents of our exchanges, our exchange members have certain rights that relate primarily to trading right protections, certain trading fee protections and certain membership benefit protections. Additionally, our Class B shareholders, who are members of our CME exchange, are entitled to elect six directors to our board even if their Class A share ownership interest is very small or non-existent. We have limited ability to eliminate these election rights, and prior attempts to do so did not receive the necessary shareholder approvals. In connection with these rights, our ability to take certain actions that we may deem to be in the best interests of the company and its shareholders, including actions relating to certain pricing decisions, may be limited by the rights of our members.

**ITEM 1C.&nbsp;&nbsp;&nbsp;&nbsp;CYBERSECURITY**

As a highly regulated global financial services company, we understand the substantial operational risks for companies in our industry as well as the importance of protecting the information and data of our clients, third parties and employees and the resilience of our systems. As such, our GIS Program is designed and operated to mitigate information security risks and threats to the company. Its intent is to safeguard the confidentiality, integrity and availability of our information and services. The GIS Program is designed to strengthen the integrity of the global markets we support, protect CME Group's information assets, maintain client, third party and employee trust, support our pursuit of strategic objectives, contribute to shareholder value and preserve our reputation and brand. We implement technical, physical and administrative safeguards to protect the confidential and sensitive information of our clients, third parties, employees and other information under CME Group's stewardship. We manage cybersecurity risk to the organization as part of our business strategy, risk management and financial functions in alignment with our overall Enterprise Risk Management Program and regularly engage with the risk committee of the board of directors and the board of directors as a whole regarding the effectiveness of the GIS Program and the management of our cybersecurity risks.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

Our GIS Program is led by the individual serving in the role of Chief Information Security Officer (CISO). Our former CISO transitioned to a new role at another company. We have appointed an interim CISO while we complete our search for a permanent replacement. Our interim CISO has over 25 years of technology experience and 22 years as a senior leader within CME Group's information security operations and incident response program. The CISO reports to our Chief Information Officer (CIO), a member of our Management Team. Our GIS team is comprised of over 250 full-time employees, many of whom hold cybersecurity, risk, or management certifications, such as Certified Information Systems Security Professional, Certified Information Security Manager, Certified in Risk and Information Systems Control, Series 99, Certified Information Systems Auditor, Project Management Professional, various cloud provider certifications and various levels of certifications demonstrating expertise in technology infrastructure. As part of our GIS Program, CME Group operates a Cyber Defense Center that virtually links 24/7 to our international cybersecurity teams and serves as a global hub for cybersecurity risk management activities, including log collection, event monitoring, threat detection and incident response, resiliency, operations, vulnerability management and the proactive collection and processing of both open source and proprietary threat and intelligence feeds allowing the company to efficiently manage, investigate and respond to cybersecurity events. Our GIS team conducts analyses and aims to prevent, detect and respond to systemic events that might threaten our company, industry or the economy.

The GIS Program includes a Cyber Defense team, which manages the Incident Response Plan (Response Plan), and consists of subject matter experts from GIS and Information Governance, who work together to monitor and respond to cybersecurity incidents. The Response Plan outlines our cyber and incident response policies and governs our incident response lifecycle, which divides overall incident response into serial phases. The Crisis Management Team is responsible for oversight during an incident, in conjunction with the Cyber Coordination Team. The Cyber Coordination Team manages responses to cybersecurity and compliance incidents, collaborating with subject matter experts from various departments in response to specific incidents. When an incident reaches a certain threshold of severity, our CISO and CIO escalate the matter to our Chief Operating Officer, who is a member of our Management Team, to determine next steps, as well as possible customer and external communications. Throughout the incident response process, the Legal team is engaged, as appropriate, and helps consider whether disclosure is required once a determination is made in connection with the company's leadership and the Crisis Management Team.

We identify, assess and manage material risks from cybersecurity threats through our GIS Program as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We deploy a defense-in-depth strategy, acknowledging the importance of people, processes and technology in upholding information security. The strategy incorporates multiple layers of controls, including, monitoring, vulnerability management, identity and access management and security assessments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our program is aligned with the National Institute of Standards and Technology Cybersecurity Framework and other technical standards and frameworks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have a robust cybersecurity defense response plan that provides a documented framework for handling security incidents and facilitates coordination across multiple parts of the company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We invest in threat intelligence and operate a Cyber Defense Center, which acts as our hub of information sharing and threat intelligence analysis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We incorporate external expertise and reviews into our cybersecurity risk management program and continue to engage leading professional consulting firms to assist our company in incorporating cybersecurity best practices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We provide annual cybersecurity awareness and ongoing phishing training, and we routinely conduct cybersecurity attack simulation exercises, which includes participation from various levels of management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Following a risk-based approach, we conduct due diligence reviews of our third-party service providers for potential cybersecurity risks to the company. We also maintain a cross-functional Third Party Risk Management program, which partners with our GIS, Information Governance, and Operational Resilience teams, among others, to manage and monitor third party risk presented by CME Group vendors and certain third parties of third parties (fourth parties). The teams conduct initial due diligence on vendors and monitor cyber-related incidents and known vulnerabilities with the goal of enhancing processes, improving risk management and partnering on exit planning and testing for certain vendors associated with essential functions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have insurance against certain cybersecurity and privacy risks and attacks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are an active participant in the financial services industry and government forums and information sharing programs, designed to improve both internal and sector cybersecurity defense. These valuable external partnerships are established and maintained in order to gain more timely, comprehensive and actionable threat information across geographies and industries and to facilitate the exchange of best practices and security techniques. They allow for a high degree of collaboration and cooperation with local, state, federal, and international law enforcement and intelligence agencies, industry groups, and other private sector chief information security officers.

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We regularly test the design and effectiveness of our information security controls and processes through a program of testing performed by internal and independent third-party teams. Remediation of gaps and opportunities identified through testing are tracked through to closure. Testing activities support a variety of regulatory requirements and external industry certifications held by CME Group.

The board provides oversight of cybersecurity risks and has designated primary responsibility to the risk committee which oversees our information security programs, including cybersecurity, and is actively involved in monitoring the progress of key cybersecurity initiatives. Our board and risk committee receive regular updates on the activities and effectiveness of our GIS Program, including reports on incident response plan testing exercises and results of compliance testing and third-party evaluation results. Our CISO provides quarterly, or as needed, reports and updates to our board and risk committee on the company's cybersecurity risk management program and meets with the risk committee at least annually in a private session. The CISO has an indirect reporting line to the risk committee. We also engage with leading professional consulting firms to provide periodic updates to the board on cybersecurity-related risks in the evolving threat landscape and to provide education on best practices for board oversight of our GIS Program.

To date, the company is not aware of risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the company, including our business strategy, results of operations or financial condition.

See "Item 1A - Risk Factors" beginning on page [16](#i93ed40d324b64de799da10954483467e_31) for additional information on cyber attacks and other cybersecurity risks the company faces.

***Class A Common Stock***

Our Class A common stock is currently listed on Nasdaq under the ticker symbol "CME." As of February 11, 2026, there were approximately 3,650 holders of record of our Class A common stock.

***Class B Common Stock***

Our Class B common stock is not listed on a national securities exchange or traded in an organized OTC market. Each class of our Class B common stock is associated with a membership in a specific division of our CME exchange. CME's rules provide exchange members with trading rights and the ability to use or lease these trading rights. Each share of our Class B common stock can be transferred only in connection with the transfer of the associated trading rights.

Class B shares and the associated trading rights are bought and sold or leased through our membership department. Although our Class B shareholders have special voting rights, because our Class B shares have the same equitable interest in our earnings and the same dividend payments as our Class A shares, we expect that the market price of our Class B common stock, if reported separately from the associated trading rights, would be primarily determined by the value of our Class A common stock. As of February 11, 2026, there were approximately 1,430 holders of record of our Class B common stock.

**EXECUTIVE SUMMARY**

**Business Overview**

CME Group, a Delaware stock corporation, is the holding company for CME, CBOT, NYMEX, COMEX, NEX Group plc (NEX) and their respective subsidiaries. The holding company structure is designed to provide strategic and operational flexibility. CME Group's Class A common stock is listed on the Nasdaq Global Select Market (Nasdaq) under the ticker symbol "CME."

Our exchange consists of designated contract markets for the trading of futures and options contracts. We also clear futures, options and swaps contracts through our clearing house. Futures contracts, options contracts and swaps contracts provide investors with vehicles for protecting against, and potentially profiting from, price changes in financial instruments and physical commodities.

We are a global company with customer access available virtually all over the world. Our customers consist of professional traders, financial institutions, individual and institutional investors, major corporations, manufacturers, producers, governments and central banks. Customers include both members of the exchange and non-members.

We offer our customers the opportunity to trade futures contracts and options contracts on a range of products, including those based on interest rates, equity indexes, foreign exchange, energy, metals and agricultural commodities. Through our cash markets business, we offer fixed income trading through BrokerTec and foreign currency trading through EBS. Our products provide a means for hedging, speculating and allocating assets. We identify new products by monitoring economic trends and their impact on the risk management and speculative needs of our existing and prospective customers.

Most of our products are available for trading through our electronic trading platforms. These execution facilities offer our customers immediate trade execution and price transparency. In addition, trades can be executed through privately negotiated transactions that are cleared and settled through our clearing house.

Our clearing house clears, settles and guarantees futures and options contracts traded through our exchanges, in addition to cleared swaps products. Our clearing house's performance guarantee is an important function of our business. Because of this guarantee, our customers do not need to evaluate the credit of each potential counterparty or limit themselves to a selected set of counterparties. This flexibility increases the potential liquidity available for each trade. Additionally, the substitution of our clearing house as the counterparty to every transaction allows our customers to establish a position with one party and offset the position with another party. This contract offsetting process provides our customers with flexibility in establishing and adjusting positions and provides for collateral and margining efficiencies. Certain BrokerTec contracts are cleared at third-party clearing houses.

**Business Trends**

**Economic Environment.** Our customers continue to use our markets as an effective and transparent means to manage risk and meet their investment needs. Trading activity in our centralized markets has fluctuated due to the ongoing uncertainty in the financial markets, fluctuations in the availability of credit, variations in the amount of assets under management as well as the

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

Federal Reserve Bank's interest rate policy. We continue to maintain high quality and diverse products as well as various clearing and market data services, which support our customers in any economic environment.

**Competitive Environment.** Our industry is competitive and we continue to encounter competition in all aspects of our business. We expect competition to continue to intensify, especially in light of ongoing regulatory developments in the financial services industry. Competition is influenced by our brand and reputation; the efficiency and security of our clearing, settlement and support services; depth and liquidity of our markets; capital and margin efficiencies; diversity of product offerings, including frequency and quality of new product development and innovative services; our ability to position and expand upon existing products to address changing market needs; efficient and seamless customer experience; transparency, reliability, anonymity and security of transaction processing; the regulatory environment; connectivity, accessibility, flexibility in execution methods, and distribution; and technology capability and innovation, as well as overall transaction costs. We believe we are very well positioned with respect to these factors. Our asset classes contain products designed to address differing risk management needs, and customers are able to achieve operational and capital efficiencies by accessing our diverse products through our platforms and our clearing house. We compete in a large and expanding financial services trading, clearing and settlement marketplace globally. As markets continue to evolve, we will continue to adapt our trading technology and clearing services to meet the needs of our customers. The competitive environment to which we are subject is discussed in "Item 1 - Business" beginning on page [10](#i93ed40d324b64de799da10954483467e_22).

**Regulatory Environment.** Our exchange-traded derivatives exchanges and other businesses are regulated and we serve a customer base that includes regulated institutions and individuals. Developments in the regulatory environment have the potential to significantly impact our business. Compliance with regulations may require us and our customers to dedicate significant financial and operational resources, which could adversely affect our profitability. The regulatory environment to which we are subject is discussed in "Item 1 - Business" beginning on page [12](#i93ed40d324b64de799da10954483467e_25).

**Business Strategy**

Our strategy focuses on maximizing futures and options growth globally, diversifying our business and revenues and delivering unparalleled customer efficiencies and operational excellence, including through our partnership with Google Cloud. This strategy allows us to continue to develop into a more broadly diversified financial exchange that provides trading and clearing solutions across a wide range of products and asset classes. Our strategic initiatives are discussed in "Item 1 - Business" beginning on page [7](#i93ed40d324b64de799da10954483467e_16).

**Revenues**

**Clearing and transaction fees.** A majority of our revenue is derived from clearing and transaction fees, which include electronic trading fees, surcharges for privately negotiated transactions and other volume-related charges for exchange-traded and over-the-counter (OTC) contracts. Because clearing and transaction fees are assessed on a per-contract or notional value basis, revenues and profitability fluctuate with changes in contract volume. In addition to the business trends noted earlier, our contract volume, and consequently our revenues, tend to increase during periods of economic and geopolitical uncertainty as our customers seek to manage their exposure to, or speculate on, the market volatility resulting from that uncertainty.

While volume has the most significant impact on our clearing and transaction fees revenue, there are four other factors that also influence this source of revenue:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• rate structure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• product mix;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• venue; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the percentage of trades executed by customers who are members compared with non-member customers.

*Rate structure.* Customers benefit from volume discounts and limits on fees as part of our effort to increase liquidity in certain products. We offer various incentive programs to promote trading and clearing in various products and geographic locations. We may periodically change fees, volume discounts, fee limits and member discounts, perhaps significantly, based on our review of operations and the business environment.

*Product mix.* We offer exchange-traded futures and options contracts as well as cleared-only interest rate swap contracts and event contracts. We also offer foreign exchange spot and forward contracts and fixed income products. Rates are varied by product in order to optimize revenue on existing products and to encourage contract volume upon introduction of new products.

*Venue.* Our exchange and platforms are an international marketplace that brings together buyers and sellers mainly through our electronic trading as well as through open outcry trading and privately negotiated transactions. Any customer who is guaranteed by a clearing firm and who agrees to be bound by our exchange rules is able to obtain direct access to our

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

electronic platforms. Open outcry trading is conducted exclusively by our members, who may execute trades on behalf of customers or for themselves. Open outcry trading is limited to Secured Overnight Financing Rate (SOFR) options products.

Typically, customers submitting trades through our electronic platforms are charged fees for using the platforms in addition to the fees assessed on all transactions executed on our exchange. Customers entering into privately negotiated transactions also incur additional charges beyond the fees assessed on other transactions.

*Member/non-member mix.* Generally, member customers are charged lower fees than our non-member customers. Holding all other factors constant, revenue decreases if the percentage of trades executed by members increases, and increases if the percentage of non-member trades increases.

*Clearing and transaction fees for cash markets business*. Our cash markets business provides matching services whereby we match a buyer and seller of financial instruments to allow both parties to complete the trade bilaterally or through a third-party clearing house. We are not involved in the settlement of the contract but charge a transaction fee generally based on volume or notional value of the trade for providing the matching service. BrokerTec Americas also generates revenue from a matched principal business. This business serves as a fully matched counterparty to offsetting positions entered into by clients on our electronic trading platform to facilitate anonymity and access to clearing and settlement. Revenue is generated from this business generally on a transaction fee basis.

**Other sources.** Revenue is also derived from other sources, including market data and information services and other various services related to our exchange operations.

*Market data and information services.* We receive market data and information services revenue from the dissemination of our market data to subscribers. Subscribers can obtain access to our market data services either directly or through third-party distributors.

Our service offerings include access to real-time, delayed and end-of-day quotations, trade and summary market data for our products and other data sources. Users of our basic service receive real-time quotes and pay a flat monthly fee for each screen, or device, displaying our market data. Alternatively, customers can subscribe to market data provided on a limited group of products. The fee for this service is also a flat rate per month.

Pricing for our market data services is based on the value of the service provided and the price of comparable services offered by our competitors. Increases or decreases in our market data and information services revenue are influenced by changes in our price structure and incentive programs for existing market data offerings, introduction of new market data services and changes in the number of devices in use. General economic factors that affect the financial services industry, which constitutes our primary customer base, also influence revenue from our market data services.

*Other revenues.* Other revenue includes access and communication fees. Access and communication fees are connectivity fees charged to members and clearing firms that utilize our various telecommunications networks and communications services. Our communication services include our co-location program as well as the connectivity charges to customers of the CME Globex platform. Access fee revenue varies depending on the type of connection provided to customers.

Other revenues also include fees for collateral management, equity subscription fees and fees for trade order routing through agreements from various strategic relationships as well as other services to members and clearing firms.

**Expenses**

The majority of our expenses do not vary directly with changes in our contract volume. However, licensing and other fee agreements can vary directly with certain equity, energy and swap volumes.

**Compensation and benefits.** Compensation and benefits expense is our most significant expense and includes employee wages, bonuses, stock-based compensation, benefits and employer taxes. Changes in this expense are driven by fluctuations in the number of employees, increases in wages as a result of labor market conditions, changes in rates for employer taxes and other cost increases affecting benefit plans. In addition, this expense is affected by the composition of our workforce. The expense associated with our bonus and stock-based compensation plans can also have a significant impact on this expense category.

The bonus component of our compensation and benefits expense is based on our financial performance. Under the performance criteria of our annual incentive plans, the bonus funded under the plans is based on achieving certain financial performance targets established by the compensation committee of our board of directors. The compensation committee has discretion to make equitable adjustments to the cash earnings performance calculation to reflect effects of unplanned operating results or capital expenditures to meet intermediate- to long-term growth opportunities.

In general, stock-based compensation is a non-cash expense related to restricted stock and performance share grants. Stock-based compensation varies depending on the quantity and fair value of awards granted. The fair value of restricted stock awards

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

and other performance share grants is based on either the share price on the date of the grant or a model of expected future stock prices.

**Professional fees and outside services.** This expense includes fees for consulting services received on strategic and technology initiatives; regulatory and other compliance matters; temporary labor as well as legal and accounting fees. This expense may fluctuate as a result of changes in services required to complete initiatives, handle legal proceedings and comply with regulatory and compliance requirements.

**Depreciation and amortization.** Depreciation and amortization expense results from the depreciation of long-lived assets such as buildings, leasehold improvements, furniture, fixtures and equipment. This expense also includes the amortization of purchased and internally developed software.

**Amortization of purchased intangibles.** Amortization of purchased intangibles includes amortization of intangible assets obtained in our acquisitions of CBOT Holdings, Inc., NYMEX Holdings, Inc. and NEX as well as other asset and business acquisitions. Intangible assets subject to amortization consist primarily of clearing firm, market data and other customer relationships.

**Other expenses.** We incur additional ongoing expenses for technology, licensing and other fee agreements and various other activities necessary to support our operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Technology expense consists of costs related to maintenance of the hardware and software required to support our technology. It also includes costs for network connections for our electronic platforms and some market data customers; telecommunications costs of our exchange, and fees paid for access to external market data. This expense may be driven by system capacity, cloud consumption, functionality and redundancy requirements. It also may be impacted by growth in electronic contract volume and changes in the number of telecommunications hubs and connections which allow customers outside the U.S. to access our electronic platforms directly.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Licensing and other fee agreements expense includes license fees paid as a result of contract volume in equity index products. This expense also includes royalty fees and broker rebates on energy and metals products, as well as revenue sharing on cleared swaps contracts and some new product launches. This expense fluctuates with changes in contract volumes as well as changes in fee structures.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Other expenses include occupancy and building operations expenses including rent, maintenance, real estate taxes, utilities and other related costs related to leased property in Chicago, New York, the UK, and India, as well as other smaller locations throughout the world. Other expenses also include marketing and travel-related expenses as well as general and administrative costs. Marketing, advertising and public relations expense includes media, print and other advertising costs, as well as costs associated with our product promotion. Other expenses also include litigation and customer settlements, impairment charges on operating assets, gains and losses on disposals of certain operating assets, and foreign currency transaction gains and losses resulting from changes in exchange rates on certain foreign monetary assets and liabilities.

**Non-Operating Income and Expenses**

Income and expenses incurred through activities outside of our core operations are considered non-operating. These activities include non-core investing and financing activities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Investment income includes income from short-term investment of clearing firms' cash performance bonds and guaranty fund contributions as well as excess operating cash; interest income and realized gains and losses from our marketable securities; realized gains and losses and dividend income from our strategic equity investments, and gains and losses on trading securities in our non-qualified deferred compensation plans. Investment income is influenced by market interest rates, changes in the levels of cash performance bonds deposited by clearing firms, the amount of dividends distributed by our strategic investments and the availability of funds generated by operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Interest and other borrowing costs expense includes charges associated with various short-term and long-term funding facilities, including commitment fees on lines of credit agreements.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Equity in net earnings (losses) of unconsolidated subsidiaries includes income and losses from our investments in FanDuel Prediction Markets Holdings LLC, S&P Dow Jones Indices LLC, OSTTRA, Shanghai CFETS-NEX International Money Broking Co., Ltd. and Gulf Mercantile Exchange.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Other income (expense) includes expenses related to the distribution of a portion of interest earned on performance bond collateral reinvestment to the clearing firms, gains and losses on derivative contracts and other various income and expenses outside our core operations.

**CRITICAL ACCOUNTING POLICIES**

The notes to our consolidated financial statements include disclosure of our significant accounting policies. In establishing these policies within the framework of accounting principles generally accepted in the United States (U.S.), management must make certain assessments, estimates and choices that will result in the application of these principles in a manner that appropriately reflects our financial condition and results of operations. Critical accounting policies are those policies that we believe present the most complex or subjective measurements and have the most potential to affect our financial position and operating results. While all decisions regarding accounting policies are important, there are certain accounting policies that we consider to be critical. These critical policies, which are presented in detail below, relate to the valuation of financial instruments, goodwill and intangible assets, revenue recognition, income taxes and internal use software costs.

**Valuation of financial instruments.** Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date, or an exit price. We have categorized financial instruments measured at fair value into the following three-level fair value hierarchy based upon the level of judgment associated with the inputs used to measure the fair value:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 inputs, which are considered the most reliable evidence of fair value, consist of quoted prices (unadjusted) for identical assets or liabilities in active markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 inputs consist of observable market data, such as quoted prices for similar assets and liabilities in active markets, or inputs other than quoted prices that are directly observable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 inputs consist of unobservable inputs, which are derived and cannot be corroborated by market data or other entity-specific inputs.

For further discussion regarding the fair value of financial assets and liabilities, see note 2. Summary of Significant Accounting Policies and note 17. Fair Value Measurements to the consolidated financial statements.

**Goodwill and intangible assets.** We review goodwill for impairment on a quarterly basis and whenever events or circumstances indicate that its carrying value may not be recoverable. Goodwill may be tested quantitatively for impairment by comparing the carrying value of a reporting unit to its estimated fair value. Estimating the fair value of a reporting unit involves the use of valuation techniques that rely on significant estimates and assumptions. These estimates and assumptions may include forecasted revenue growth rates; forecasted operating margins; risk-adjusted discount rates; forecasted economic and market conditions; and industry multiples. We base our fair value estimates on assumptions we believe to be reasonable given the information that is available to us at the time of our assessment; however, actual future results may differ significantly from those estimates. Under certain favorable circumstances, goodwill may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value. The qualitative assessment of goodwill may rely on significant assumptions about forecasts of revenue growth, operating margins and economic conditions as well as overall market and industry-specific trends. In addition, the carrying value of goodwill, as denominated in foreign currencies, is adjusted each reporting period as a result of movements in foreign currency exchange rates relative to the U.S. dollar. Such foreign currency translation adjustments are recorded in accumulated other comprehensive income (loss) within shareholders' equity.

We also review indefinite-lived intangible assets on a quarterly basis or more frequently when events and circumstances indicate that their carrying values may not be recoverable. Indefinite-lived intangible assets may be tested quantitatively for impairment by comparing their carrying values to their estimated fair values. Estimating the fair value of indefinite-lived intangible assets involves the use of valuation techniques that rely on significant estimates and assumptions. These estimates and assumptions may include forecasted revenue growth rates, forecasted allocations of expense and risk-adjusted discount rates. We base our fair value estimates on assumptions we believe to be reasonable given the information that is available to us at the time of our assessment; however, actual future results may differ significantly from those estimates. Similar to goodwill, under certain favorable circumstances, indefinite-lived intangible assets may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value. The qualitative assessment of indefinite-lived intangible assets may rely on significant assumptions about forecasts of revenue growth, operating margins and economic conditions as well as overall market and industry-specific trends.

Intangible assets subject to amortization are also assessed for impairment on a quarterly basis or more frequently when indicated by a change in economic or operational circumstances. The impairment assessment of these assets requires management to first compare the carrying value of the amortizing asset to its undiscounted net cash flows. If the carrying value exceeds the undiscounted net cash flows, management is then required to estimate the fair value of the assets and record an impairment loss for the excess of the carrying value over the fair value. In connection with this impairment assessment, management also challenges the useful lives of our definite-lived intangible assets.

**Revenue recognition.** A significant portion of our revenue is derived from the clearing and transaction fees we assess on each contract executed through our trading venues and cleared through our clearing house. Clearing and transaction fees are recognized as revenue when a buy and sell order are matched, novated and when the trade is cleared. On occasion, the

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

customer's exchange trading privileges may not be properly entered by the clearing firm and incorrect fees are charged for the transactions in the affected accounts. When this information is corrected within the time period allowed by the exchange, a fee adjustment is provided to the clearing firm. We also earn revenue from the dissemination of market data to subscribers, distributors, and other third-party licensees of market data. Market data and information services fee revenue is generally recognized on a monthly basis as the customers receive and consume the benefit of the market data services.

**Income taxes.** Calculation of the income tax provision includes an estimate of the income taxes that will be paid for the current year, as well as an estimate of income tax liabilities or benefits deferred into future years. Deferred tax assets are reviewed to determine if they will be realized in future periods. To the extent it is determined that some deferred tax assets may not be fully realized, the assets are reduced to their realizable value by a valuation allowance. The calculation of our tax provision involves uncertainty in the application of complex tax regulations and we occasionally may consult with relevant tax authorities or engage third-party expertise where appropriate. We recognize potential liabilities for anticipated tax audit issues in the U.S. and other applicable foreign tax jurisdictions using a more-likely-than-not recognition threshold based on the technical merits of the tax position taken or expected to be taken. If the actual obligation of these amounts varies from our estimate, our income tax provision would be reduced or increased at the time that determination is made. This determination may not be known for several years. Past tax audits have not resulted in tax adjustments that led to a material change to the income tax provision in the year the audit was completed. The effective tax rate, defined as the income tax provision as a percentage of income before income taxes, will vary from year to year based on changes in tax jurisdictions, tax rates and regulations. In addition, the effective tax rate will vary with changes to income that are not subject to income tax and changes in expenses or losses that are not deductible, such as the utilization of foreign net operating losses.

**Internal use software costs.** Certain internal and external costs that are incurred in connection with developing or obtaining software for internal use are capitalized. We also enter into software hosting arrangements for software projects maintained or developed in the cloud. Software development costs incurred during the planning or maintenance stages of a software project are expensed as incurred, while certain costs incurred during the application development stage are capitalized and are amortized over the estimated useful life of the software, which is generally two to four years, but up to eight years for certain trading and clearing applications. Amortization of capitalized costs begins only when the software becomes ready for its intended use. In addition, software assets are assessed for impairment when events or circumstances indicate that the carrying values may not be recoverable or that a reduction in the estimated useful lives is warranted.

***Clearing and Transaction Fees***

<u>Futures and Options</u> 

The following table summarizes our total contract volume, revenue and average rate per contract for futures and options. Total contract volume includes contracts that are traded on our exchange and cleared through our clearing house and certain cleared-only contracts. Volume is measured in round turns, which is considered a completed transaction that involves a purchase and an offsetting sale of a contract. Average rate per contract is determined by dividing total clearing and transaction fees by total contract volume. Contract volume and average rate per contract disclosures below exclude trading volume for event contracts, the cash markets business as well as interest rate swaps.

---

Average rate per contract is impacted by our rate structure, including volume-based incentives, product mix, trading venue and the percentage of volume executed by customers who are members compared with non-member customers. Due to the relationship between average rate per contract and contract volume, the change in clearing and transaction fees attributable to changes in each is only an approximation.

Market volatility remained high throughout most of 2025. Interest rate and equity index volatility was higher as a result of mixed inflation levels, the threat of anticipated and implemented tariffs, and market uncertainty surrounding the Federal Reserve's interest rate policy decisions. The Federal Open Markets Committee (FOMC) cut the federal funds rate multiple times throughout 2025 and issued cautious guidance for the future. In addition, market uncertainty also remained high within the energy, agricultural commodities, and metals markets throughout 2025. This was mainly due to new and existing geopolitical tensions, the anticipation and implementation of tariffs, and uncertain weather conditions in 2025. Finally, we also continued to expand product offerings across many of our asset classes which contributed to volume and sales growth across the globe. We believe these factors contributed to the increase in total volume in 2025 compared with 2024.

In 2025 compared with 2024, overall interest rate contract volume increased as a result of higher overall market volatility. We believe this was a result of mixed inflation results that occurred throughout the year, as well as uncertainty surrounding the Federal Reserve's interest rate policy decisions. In addition, new and existing geopolitical tensions as well as the potential economic impacts of anticipated and implemented tariffs also led to higher overall interest rate contract volume in 2025.

| Bitcoin futures and options | 101 | 68 | 48 |

---

Equity index contract volume increased in 2025 compared with 2024, as a result of higher overall volatility. We believe this higher volatility was due to the potential economic impacts of anticipated and implemented tariffs that occurred in the first half of 2025 as well as new and existing geopolitical tensions that occurred throughout the year. We also believe that higher volatility within the technology sector as a result of continued market speculation about artificial intelligence initiatives also contributed to higher Nasdaq-100 contract volume.

Our cryptocurrency contract volume was higher in 2025 when compared to 2024, as a result of the continued broader acceptance of cryptocurrency products.

We believe these factors led to the overall increase in equity complex volume in 2025 when compared with 2024.

*Foreign Exchange Products*

| Canadian dollar | 91 | 104 | (13) |

---

Overall foreign exchange contract volume decreased in 2025 when compared with 2024, which we believe is due to lower overall volatility. We believe this was the result of less variability surrounding the global central bank's interest rate policies, which has led to overall decreases in foreign exchange contract volumes.

*Energy Products*

The following table summarizes average daily volume for our key energy products.

| Refined products | 396 | 375 | 6 |
| Brent crude oil | 173 | 109 | 59 |

---

Overall energy contract volume increased in 2025 when compared with 2024, due to higher overall volatility. We believe crude oil volatility was higher as a result of geopolitical tensions across the globe, a shift in global supply levels, and the potential economic impacts of anticipated and implemented tariffs. Natural gas volatility remained high as a result of uncertain weather conditions and a shift in supplies in the U.S. in 2025, which impacted prices throughout the year. We believe these factors contributed to higher overall energy volume in 2025 compared with 2024.

| Wheat | 240 | 228 | 5 |

---

In 2025 when compared with 2024, overall commodity contract volume increased due to higher overall market volatility. We believe the increase was a result of uncertainty surrounding the potential economic impacts of anticipated and implemented tariffs as they relate to the commodities market. In addition, changes in market expectations regarding grain supplies as well as uncertain weather conditions in 2025 also led to an increase in volume.

*Metal Products*

The following table summarizes average daily volume for our key metal products.

| Gold | 683 | 431 | 58% |
| Silver | 153 | 123 | 24 |
| Copper | 96 | 133 | (28) |

---

Overall metal contract volume increased in 2025 when compared with 2024. We believe gold and silver volumes increased as a result of increased price volatility caused by investors using these metals as a safe-haven alternative investment due to uncertainty in other markets. In addition, the increase in volume was due to additional use of our metal products by our retail client base. The decrease in copper volume is due to reductions in demand for the metal due to economic instability as well as the continued tariff risk associated with copper. We believe these factors contributed to higher overall metals volume in 2025 when compared with 2024.

***Average Rate per Contract***

The average rate per contract increased slightly in 2025 when compared with 2024. The overall increase is primarily due to the increase in our fee structure, which went into effect on February 1, 2025. The increase is also due to a change in product mix. Interest rate contract volume decreased by 1 percentage point as a percent of total volume, while all other products collectively increased by 1 percentage point. The increase was partially offset by higher volume tier-based incentives.

<u>Cash Markets Business</u>

Total clearing and transaction fees revenue in 2025 included $283.7 million of transaction fees attributable to the cash markets business, compared with $276.7 million in 2024. This revenue primarily includes transaction fees from BrokerTecs's fixed income volume and EBS foreign exchange volume.

The related average daily notional value for the years ended 2025 and 2024 for key cash markets products were as follows:

---

| | | | |
|:---|:---|:---|:---|
| | | | **Year-over-Year Change** |
|<br>**(amounts in billions)** | **2025** | **2024** | **2025-2024** |
| U.S. Repos | $365.7 | $301.6 | 21% |
| European Repo (in euros) | 307.8 | 290.1 | 6 |
| U.S. Treasury | 96.6 | 101.9 | (5) |
| Spot FX | 63.8 | 59.5 | 7 |

---

Overall average daily notional values for the cash markets business were higher in 2025 when compared with the same period in 2024 due to higher overall U.S. debt issuances. U.S. debt issuances were significantly higher in 2025 as a result of the increase of the debt ceiling in early 2025, which resulted in an increase in U.S. Repo volumes. Volume for the U.S. Treasury cash markets products declined slightly due to lower expected future volatility within the Treasury market.

***Concentration of Revenue***

We bill a significant portion of our clearing and transaction fees to our clearing firms. The majority of clearing and transaction fees received from clearing firms represent charges for trades executed and cleared on behalf of their customers. One clearing firm represented 12% of our clearing and transaction fees in 2025. Should a clearing firm withdraw, we believe that the customer portion of the firm's trading activity would likely transfer to another clearing firm of the exchange. Therefore, we do not believe we are exposed to significant risk from an ongoing loss of revenue received from or through a particular clearing firm.

**Other Sources of Revenue**

*Market data and information services.* In 2025 when compared with 2024, the increase in market data and information services revenue was largely attributable to price increases for certain products as well as an increase in usage for certain products.

Approximately 30% of our market data and information services revenue in 2025 was earned from the two largest resellers of our market data. Despite this concentration, we consider exposure to significant risk of revenue loss to be minimal. In the event that one of these vendors no longer distributes our market data, we believe the majority of that vendor's customers would likely subscribe to our market data through another reseller. Additionally, several of our largest institutional customers that utilize services from our two largest resellers report usage and remit payment of their fees directly to us.

***2025 Compared With 2024***

Operating expenses increased by $92.5 million in 2025 when compared with 2024. The following table shows the estimated impact of key factors resulting in the net increase in operating expenses.

---

| | | |
|:---|:---|:---|
| **(dollars in millions)** | **Year-<br>over-Year<br>Change** | **Change as a<br>Percentage of<br>2024 Expenses** |
| Salaries, benefits and employer taxes | $41.6 | 2% |
| Technology support services | 27.5 | 1 |
| OSTTRA sale professional fees | 22.1 | 1 |
| License fees | 17.2 | 1 |
| Legal fees | 15.0 | 1 |
| Google Cloud professional fees | (13.4) | (1) |
| Occupancy and building operations | (16.2) | (1) |
| Other expenses, net | (1.3) |  |
| Total | $92.5 | 4% |

---

Overall operating expenses increased in 2025 when compared with 2024 due to the following reasons:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Salaries, benefits and employer taxes expense was higher as a result of salary increases that went into effect during the first quarter of 2025 as well as an increase in headcount during the year, which was primarily attributable to additional headcount in the company's international locations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The increase in expense related to technology support services was primarily driven by higher third party services license fees and software license fees to support the ongoing Google Cloud transformation project.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Professional fees expense increased due to transaction-related costs including banking and legal fees resulting from the sale of the OSTTRA joint venture in the fourth quarter of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• License fees expense was higher primarily due to an increase in volume for certain equity products as well as the addition of multiple new products during 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Legal fees were higher primarily due to the class action lawsuit litigation in the second and third quarter of 2025.

Decreases in operating expenses in 2025 when compared with 2024 were due to the following reasons:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The decrease in professional fees related to the Google Cloud transformation project, which began in late 2021, was the result of a shift in need from an overall project consulting focus to a technology migration focus.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Occupancy and building operations expense primarily decreased due to gains recognized in 2025 due to a reduction in our leased office space as well as lower rent and data center occupancy costs.

| Total Non-Operating | $1101.0 | $609.9 | 81 |

---

*Investment income*. In 2025 when compared with 2024, there was an increase in earnings from reinvested cash performance bond and guaranty fund contributions due to higher average reinvestment balances. In 2025 and 2024, earnings from cash performance bond and guaranty fund contributions were $5,253.6 million and $3,943.8 million, respectively. In addition, there was an increase in net realized and unrealized gains on investments, including the $306.1 million gain on the sale of the OSTTRA joint venture.

*Equity in net earnings (losses) of unconsolidated subsidiaries.* Higher income generated from our S&P/DJI and OSTTRA business ventures contributed to an increase in equity in net earnings of unconsolidated subsidiaries in 2025 when compared with 2024.

*Other income (expense).* In 2025 when compared with 2024, we recognized higher expense related to the distribution of interest earned on performance bond collateral reinvestments to the clearing firms as a result of higher average reinvestment balances.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

In 2025 and 2024, expenses related to the distribution of interest earned on collateral reinvestments were $4,842.5 million and $3,669.4 million, respectively.

**Income Tax Provision**

The following table summarizes the effective tax rate for the periods presented:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **2025** | **2024** |  |  |  |
| **2025** | **2024** | Year ended December 31 | 23.6% | 22.4% |

---

The overall effective tax rate increased in 2025 when compared with the same period in 2024. The increase is largely due to changes in our state and local apportionment factors including remeasurement of our deferred taxes during the year.

**LIQUIDITY AND CAPITAL RESOURCES**

**Cash Requirements**

We have historically met our funding requirements with cash generated by our ongoing operations. However, we have used our commercial paper program from time to time to fund large short-term funding needs. While our cost structure is generally fixed in the short term, our sources of operating cash are largely dependent on contract trading volume levels. In addition to using our existing cash, cash equivalents, marketable securities and cash generated from operations, we may continue to utilize our commercial paper program to meet our working capital needs, capital expenditures and other commitments. It is also possible that we may need to raise additional funds to finance our activities through future public debt offerings or by direct borrowings from financial institutions through our committed revolving credit facilities.

Cash will also be required for non-cancellable purchase obligations as at December 31, 2025. Commitments include material contractual purchase obligations that are non-cancellable. Purchase obligations relate to advertising, licensing, hardware, software and maintenance as well as telecommunication services. Aside from the table below, we have certain other arrangements that have a perpetual term for which we pay a minimum of $5.0 million per year. At December 31, 2025, future minimum payments due under purchase obligations were payable as follows (in millions):

---

| | |
|:---|:---|
| **Year** | |
| 2026 | $190.7 |
| 2027-2028 | 450.7 |
| 2029-2030 | 437.8 |
| Thereafter | 524.0 |
| Total | $1603.2 |

---

Future capital expenditures for technology are anticipated as we continue to support our growth through increased system capacity, performance improvements, integration of acquired platforms and improvements to some of our office spaces. Each year, capital expenditures are incurred for improvements to and modification of our offices, remote data centers, telecommunications network and other operating equipment. In 2026, we expect capital expenditures to total approximately $85.0 million, net of any leasehold improvement allowances. We continue to monitor our capital needs and may revise our forecasted expenditures as necessary in the future.

We intend to continue to pay a regular quarterly dividend to our shareholders, with a target of between 50% to 60% of the prior year's cash earnings. The decision to pay a dividend and the amount of the dividend, however, remains within the discretion of our board of directors and may be affected by various factors, including our earnings, financial condition, capital requirements, levels of indebtedness and other considerations our board of directors deems relevant. We are also required to comply with restrictions contained in the general corporation laws of our state of incorporation, which could limit our ability to declare and pay dividends. On February 12, 2026, the company declared a regular quarterly dividend of $1.30 per share for all outstanding common and preferred shares. The dividend will be payable on March 26, 2026 to shareholders of record on March 10, 2026. Assuming no changes in the number of shares outstanding, the first quarter dividend payment will total approximately $467.3 million. The board of directors also declared an additional, annual variable dividend of $6.15 per share on February 12, 2026 to be paid on March 26, 2026 to the shareholders of record on March 10, 2026. In general, the amount of the annual variable dividend will be determined based on prior year's performance and our expected cash needs, and the level will increase or decrease from year to year based on operating results, capital expenditures, potential merger and acquisition activity and other forms of capital return, including regular dividends and share buybacks during the prior year.

**Sources and Uses of Cash**

The following is a summary of cash flows from operating, investing and financing activities.

---

| | | | |
|:---|:---|:---|:---|
| | | | **Year-over-Year Change** |
|<br>**(dollars in millions)** | **2025** | **2024** | **2025-2024** |

| Net cash provided by (used in) investing activities | 1498.8 | (82.6) | n.m. |
| Net cash provided by financing activities | 56509.5 | 5076.5 | n.m. |

---

_________

*n.m. not meaningful*

*Operating activities*

Net cash provided by operating activities was higher in 2025 compared with 2024, largely due to an increase in revenue resulting from fee increases, an increase in overall volumes and higher interest earned on reinvestment of collateral, net of distributions.

*Investing activities*

The increase in cash provided by investing activities in 2025 compared with 2024 was due to higher proceeds on sales of investments in 2025 compared to 2024.

*Financing activities*

Cash provided by financing activities was higher in 2025 when compared with 2024 mainly due to an increase in cash performance bonds and guaranty fund contributions. This was partially offset by an increase in dividends paid in 2025.

**Debt Instruments**

The following table summarizes our debt outstanding as of December 31, 2025:

---

| | |
|:---|:---|
| **(in millions)** | **Par Value** |
| Fixed rate notes due June 2028, stated rate of 3.75% | $500.0 |
| Fixed rate notes due March 2030, stated rate of 4.40% | 750.0 |
| Fixed rate notes due March 2032, stated rate of 2.65% | 750.0 |
| Fixed rate notes due September 2043, stated rate of 5.30% <sup>(1)</sup> | 750.0 |
| Fixed rate notes due June 2048, stated rate of 4.15% | 700.0 |

_______________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)We maintained a forward-starting interest rate swap agreement that modified the interest obligation associated with these notes so that the interest payable effectively became fixed at a rate of 4.73%.

We maintain a $2.3 billion multi-currency revolving senior credit facility with various financial institutions, which matures in April 2030. The proceeds from this facility can be used for general corporate purposes, which includes providing liquidity for our clearing house in certain circumstances at CME Group's discretion and, if necessary, for maturities of commercial paper. As long as we are not in default under this facility, we have the option to increase it up to $3.3 billion with the consent of the agent and lenders providing the additional funds. This facility is voluntarily pre-payable from time to time without premium or penalty. Under this facility, we are required to remain in compliance with a consolidated net worth test, which is defined as our consolidated shareholders' equity at December 31, 2024, giving effect to share repurchases made and special dividends paid during the term of the agreement (and in no event greater than $2.0 billion in aggregate), multiplied by 0.65. We currently do not have any borrowings outstanding under this facility, but any commercial paper balance if or when outstanding can be backstopped against this facility.

We maintain a 364-day multi-currency revolving secured credit facility with a consortium of domestic and international banks to be used in certain situations by the clearing house. The facility provides for borrowings of up to $7.0 billion. We may use the proceeds to provide temporary liquidity in the unlikely event a clearing firm fails to promptly discharge an obligation to the clearing house operated by CME, in the event of a liquidity constraint or default by a depositary (custodian for our collateral), in the event of a temporary disruption with the domestic payments system that would delay payment of settlement variation between us and our clearing firms, or in other cases as provided by the CME rulebook. Clearing firm guaranty fund contributions received in the form of cash or U.S. Treasury securities as well as the performance bond assets (pursuant to the CME rulebook) can be used to collateralize the facility. At December 31, 2025, guaranty fund contributions available to

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

collateralize the facility totaled $10.7 billion. We have the option to increase the line from $7.0 billion to $10.0 billion with the consent of the agent and lenders providing the additional funds. Our 364-day facility contains a requirement that CME remain in compliance with a consolidated tangible net worth test, defined as CME's consolidated shareholder's equity less intangible assets (as defined in the agreement), of not less than $800.0 million. We currently do not have any borrowings outstanding under this facility..

The indentures governing our fixed rate notes, our $2.3 billion multi-currency revolving senior credit facility and our 364-day multi-currency revolving secured credit facility for $7.0 billion do not contain specific covenants that restrict the ability to pay dividends. These documents, however, do contain other customary financial and operating covenants that place restrictions on the operations of the company that could indirectly affect the ability to pay dividends.

At December 31, 2025, we have excess borrowing capacity for general corporate purposes of approximately $2.3 billion under our multi-currency revolving senior credit facility.

We maintain committed repurchase facility agreements amounting to a total of $1.0 billion. The committed repurchase facilities provide access to cash, secured by non-cash collateral, in the event that one or more of our clearing firms fails to promptly discharge an obligation to the clearing house. The facilities are subject to annual renewal. We currently do not have any borrowings outstanding under these facilities.

We maintain a committed facility of up to $750.0 million for foreign currency conversions. The committed foreign currency facility allows the clearing house to convert cash to another currency within generally accepted local market timeframes in the event that one or more of our clearing firms fails to promptly discharge an obligation to the clearing house. The facility is subject to annual renewal. We currently do not have any foreign currency trades outstanding under this facility.

At December 31, 2025, we were in compliance with the various covenant requirements of all our debt facilities.

CME Group, as a holding company, has no operations of its own. Instead, it relies on dividends declared and paid to it by its subsidiaries in order to provide the funds that it uses to pay dividends to its shareholders.

To satisfy our performance bond obligation with Singapore Exchange Limited, we may pledge irrevocable standby letters of credit. At December 31, 2025, the letters of credit totaled $400.0 million. We also maintain a $350.0 million line of credit to meet our obligations under this agreement.

The following table summarizes our credit ratings as of December 31, 2025:

---

| | | | |
|:---|:---|:---|:---|
| **Rating Agency** | **Short-Term<br>Debt Rating** | **Long-Term<br>Debt Rating** | **Outlook** |
| Standard & Poor's | A1+ | AA- | Stable |
| Moody's Investors Service | P1 | Aa3 | Stable |

---

Given our cash flow generation, our ability to pay down debt levels and our ability to refinance existing debt facilities, if necessary, we expect to maintain an investment grade rating. If our ratings are downgraded below investment grade within certain specified time periods due to a change of control, we are required to make an offer to repurchase our fixed rate notes at a price equal to 101% of the principal amount, plus accrued and unpaid interest. No report of any rating agency is incorporated by reference herein.

**Liquidity and Cash Management**

Cash and cash equivalents, excluding restricted cash and restricted cash equivalents, totaled $4.4 billion and $2.9 billion at December 31, 2025 and December 31, 2024, respectively. The balance retained in cash and cash equivalents is a function of anticipated or possible short-term cash needs, prevailing interest rates, our corporate investment policy and alternative investment choices. A majority of our cash and cash equivalents balance is invested in money market mutual funds that invest only in U.S. Treasury securities, U.S. government agency securities and U.S. Treasury security reverse repurchase agreements and short-term bank deposits. Our exposure to credit and liquidity risk is minimal given the nature of the investments. Cash that is not available for general corporate purposes because of regulatory requirements or other restrictions is classified as restricted cash and is included in other current assets or other assets in the consolidated balance sheets. Cash performance bonds and guarantee fund contribution assets are deemed to be restricted cash and restricted cash equivalents.

We maintain a share repurchase program under which we are authorized to repurchase up to $3.0 billion of our outstanding Class A common stock, par value $0.01 per share (the common stock), from time to time through open market transactions, block trades, privately negotiated purchase transactions or other purchase techniques and may include purchases effected pursuant to one or more trading plans established pursuant to Rule 10b5-1 under the Exchange Act. The timing of any repurchases and the number of shares repurchased under the share repurchase program are within our discretion and may be affected by various factors, including general market and economic conditions; the market price of the common stock; CME Group's earnings, financial condition, capital requirements and levels of indebtedness; legal requirements; and other

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

considerations. The share repurchase program has no expiration date, does not obligate us to acquire any particular amount of common stock and may be modified, suspended or terminated at any time. As of December 31, 2025, the maximum remaining value of shares to be repurchased was $2.7 billion.

Our practice is to have our pension plan 100% funded at each year end on a projected benefit obligation basis, while also satisfying any minimum required contribution and obtaining the maximum tax deduction. Based on our actuarial projections, we estimate that a $10.1 million additional contribution will be necessary in 2026 to meet our funding goal. However, the amount of the actual contribution is contingent on various factors, including the actual rate of return on our plan assets during 2026 and the December 31, 2026 discount rate.

**Regulatory Requirements** 

CME is regulated by the CFTC as a derivatives clearing organization (DCO). DCOs are required to maintain capital, as defined by the CFTC, in an amount at least equal to one year of projected operating expenses as well as cash, liquid securities, or a line of credit at least equal to six months of projected operating expenses. CME was designated by the Financial Stability Oversight Council as a systemically important financial market utility under Title VIII of the Dodd-Frank Wall Street Reform and Consumer Protection Act. As a result, CME must comply with CFTC regulations applicable to a systemically important DCO for financial resources and liquidity resources. CME is in compliance with all DCO financial requirements.

CME, CBOT, NYMEX and COMEX are regulated by the CFTC as designated contract markets (DCM). DCMs are required to maintain capital, as defined by the CFTC, in an amount at least equal to one year of projected operating expenses as well as cash, liquid securities or a line of credit at least equal to six months of projected operating expenses. Our DCMs are in compliance with all DCM financial requirements.

BrokerTec Americas LLC is required to maintain sufficient net capital under the Securities Exchange Act of 1934, as amended (Exchange Act), Rule 15c3-1 (the Net Capital Rule). The Net Capital Rule focuses on liquidity and is designed to protect securities customers, counterparties, and creditors by requiring that broker-dealers have sufficient liquid resources on hand at all times to satisfy claims promptly. Rule 15c3-3, or the customer protection rule, which complements Rule 15c3-1, is designed to ensure that customer property (securities and funds) in the custody of broker-dealers is adequately safeguarded. By law, both of these rules apply to the activities of registered broker-dealers, but not to unregistered affiliates. The firm began operating as a (k)(2)(i) broker-dealer in November 2017 following notification to the Financial Industry Regulatory Authority and the SEC. A company operating under the (k)(2)(i) exemption is not required to lock up customer funds as would otherwise be required under Exchange Act Rule 15c3-3.

**ITEM 7A.&nbsp;&nbsp;&nbsp;&nbsp;QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

We are subject to various market risks, including those caused by changes in interest rates, credit and foreign currency exchange rates.

**Interest Rate Risk** 

Debt outstanding at December 31, 2025 consisted of fixed-rate borrowings of $3.4 billion. Changes in interest rates impact the fair values of fixed-rate debt, but do not impact earnings or cash flows. We did not have any variable-rate borrowings at December 31, 2025.

**Credit Risk** 

*CME Clearing House*

Our clearing house acts as the counterparty to all trades consummated on our exchange as well as through a third-party exchange and swaps markets for which we provide clearing services. As a result, we are exposed to significant credit risk of third parties, including clearing firms. We are also exposed, indirectly, to the credit risk of customers of our clearing firms. These parties may default on their obligations due to bankruptcy, lack of liquidity, operational failure or other reasons.

In order to ensure performance, we establish and monitor financial requirements for our clearing firms. We set minimum performance bond requirements for exchange-traded and interest rate swaps products. For clearing firms, we establish performance bond requirements to cover at least 99% of expected price changes for a given product within a given historical period with further quantitative and qualitative considerations based on market risk. We establish haircuts applied to collateral deposited to meet performance bond requirements to cover at least 99% of expected price changes and foreign currency changes for a given asset within a given historical period with further quantitative and qualitative considerations. Haircuts vary depending on the type of collateral and maturity. We mark-to-market open positions of clearing firms at least once each business day (twice each business day for futures and options contracts) and require payment from clearing firms whose positions have lost value and make payments to clearing firms whose positions have gained value. We have the capability to mark-to-market more frequently as market conditions warrant. These practices allow our clearing house to quickly identify any clearing firms that may not be able to satisfy the financial obligations resulting from changes in the prices of their open

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

positions before those financial obligations become exceptionally large and jeopardize the ability of our clearing house to ensure performance of their open positions.

Although we have policies and procedures designed to help ensure that our clearing firms can satisfy their obligations, these policies and procedures may not succeed in detecting problems or preventing defaults. We also have in place various measures intended to enable us to cover any default and maintain liquidity.

Despite our safeguards, we cannot guarantee that these measures will be sufficient to protect us from a default or that we will not be materially and adversely affected in the event of a significant default.

We maintain two separate financial safeguard packages:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a financial safeguard package for all futures, options and OTC swap contracts other than cleared interest rate swap contracts (base package); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a financial safeguard package for cleared interest rate swap contracts.

In the unlikely event of a payment default by a clearing firm, we would first apply assets of the defaulting clearing firm to satisfy its payment obligation. These assets include the defaulting firm's guaranty fund contributions, performance bonds and any other available assets, such as assets required for clearing membership and any associated trading rights. Thereafter, if the payment default remains unsatisfied, we would use our corporate contributions designated for the respective financial safeguard package. We would then use guaranty fund contributions of other clearing firms within the respective financial safeguard package and funds collected through an assessment against non-defaulting clearing firms within the respective financial safeguard package to satisfy the deficit.

We maintain a $7.0 billion 364-day multi-currency line of credit with a consortium of domestic and international banks to be used in certain situations by our clearing house. We have the option to request an increase in the line from $7.0 billion to $10.0 billion. We may use the proceeds to provide temporary liquidity in the unlikely event of a clearing firm default, in the event of a liquidity constraint or default by a depositary (custodian of the collateral) or in the event of a temporary disruption with the payments systems that would delay payment of settlement variation between us and our clearing firms. The credit agreement requires us to pledge certain assets to the line of credit custodian prior to drawing on the line of credit. Pledged assets may include clearing firm guaranty fund deposits held by us in the form of cash or U.S. Treasury securities. Performance bond collateral of a defaulting clearing firm may also be used to secure a draw on the line. In addition to the 364-day multi-currency line of credit, we also have the option to use our $2.3 billion multi-currency revolving senior credit facility to provide liquidity for our clearing house in the unlikely event of default.

We maintain committed repurchase facility agreements amounting to a total of $1.0 billion. The committed repurchase facilities provide access to cash, secured by non-cash collateral, in the event that one or more of our clearing firms fails to promptly discharge an obligation to the clearing house. The facilities are subject to annual renewal. We currently do not have any borrowings outstanding under these facilities.

We also maintain a committed facility of up to $750.0 million for foreign currency conversions. The committed foreign currency facility allows the clearing house to convert cash to another currency within generally accepted local market timeframes in the event that one or more of our clearing firms fails to promptly discharge an obligation to the clearing house. The facility is subject to annual renewal. We currently do not have any foreign currency trades outstanding under this facility.

At December 31, 2025, aggregate performance bond deposits for clearing firms for both financial safeguard packages was $347.3 billion, including cash performance bond deposits, non-cash deposits, Interest Earnings Facility funds and letters of credit. A defaulting firm's performance bond deposits can be used in the event of default of that clearing firm.

The following shows the available assets at December 31, 2025 in the event of a payment default by a clearing firm for the base financial safeguard package after first utilizing the defaulting firm's available assets:

(1)Our clearing house designates $100.0 million of corporate contributions to satisfy a clearing firm default in the event that the defaulting clearing firm's guaranty contributions and performance bonds do not satisfy the deficit.

(2)Guaranty fund contributions of clearing firms include guaranty fund contributions required of clearing firms, but do not include any excess deposits held by us at the direction of clearing firms.

(3)In the event of a clearing firm default, if a loss continues to exist after the utilization of the assets of the defaulted clearing firm, our corporate contribution and the non-defaulting clearing firms' guaranty fund contributions, we would assess all non-defaulting clearing firms as provided in the rules governing the guaranty fund. We could assess non-defaulting clearing firms 275% of their existing guaranty fund requirements in the event of a single default, and up to a maximum of 550% of their existing guaranty fund requirements in the event of a default by multiple clearing firms, as provided in the rules. Assessment powers are calculated to reflect the potential obligation that each clearing firm could be called for in the event clearing firm's default exhausts the guaranty fund; however, the total amount available would be reduced by the defaulted clearing firms' assessment obligations since they would no longer be able to satisfy their obligations.

The following shows the available assets for the interest rate swap financial safeguard package at December 31, 2025 in the event of a payment default by a clearing firm that clears interest rate swap contracts, after first utilizing the defaulting clearing firm's available assets:

*BrokerTec Americas Matched Principal Business*

BrokerTec Americas maintains a matched principal business, where it serves as a fully matched counterparty to offsetting positions entered into by clients on its electronic trading platform to facilitate anonymity and access to clearing and settlement. BrokerTec Americas uses Fixed Income Clearing Corporation (FICC), a third-party central clearing house as well as a third-party clearing bank for the settlement of transactions and is required to post short-term margin requirements twice a business day that can vary based on the size of unsettled transactions and any adverse market changes. At December 31, 2025, the balance of the collateral at FICC was $200.0 million, which was included in other current assets on the consolidated balance sheet.

Without sufficient funds to meet its obligations, BrokerTec Americas could be exposed to risk of breach of contract with the counterparties and the inability to continue as a member of the third-party central clearing house. Transactions with clearing house members are typically confirmed and novated shortly after execution, at which point the clearing house assumes the risk of settlement. For transactions with counterparties that are not members of the third-party clearing house, settlement typically occurs on the business day following execution and, prior to settlement, BrokerTec Americas is exposed to the risk of loss in the event a counterparty fails to meet its obligations. If that were to occur, BrokerTec Americas would have the right to cover or liquidate the open position but could incur a loss as a result of market movements.

**Foreign Currency Exchange Rate Risk**

*Foreign Currency Transaction Risk* 

We have foreign currency transaction risk related to changes in exchange rates on monetary assets, liabilities, revenues and expenses held at subsidiaries where those balances and activity are denominated in a currency other than the subsidiary's functional currency. Gains and losses on foreign currency transactions result primarily from cash, debt and other monetary assets, liabilities, revenues and expenses denominated in British pounds, euros and Japanese yen.

Aggregate transaction gains (losses) for 2025, 2024 and 2023 were $(6.0) million, $(3.0) million and $(12.9) million, respectively. We expect the foreign currency gain/loss to continue to fluctuate as long as we continue to hold monetary assets and liabilities at those subsidiaries. Market uncertainty could potentially lead to significant volatility with foreign currency exchange rates, which could result in additional foreign currency gain/loss.

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

*Foreign Currency Translation Risk* 

We have foreign currency translation risk related to the translation of our foreign consolidated and unconsolidated subsidiaries' assets, liabilities, revenues and expenses from their respective functional currencies to the U.S. dollar at each reporting date. Fluctuations in exchange rates may impact the amount of assets, liabilities, revenues and expenses we report on our consolidated balance sheets and consolidated statements of income. The financial statements of those foreign subsidiaries with functional currencies other than the U.S. dollar are translated into U.S. dollars using a current exchange rate. Gains and losses resulting from this translation are recognized as a foreign currency translation adjustment within accumulated other comprehensive income, which is a component of shareholders' equity and comprehensive income. Aggregate translation gains (losses) for 2025, 2024 and 2023 were $163.2 million, $(61.0) million and $70.8 million, respectively.

*Foreign Currency Exchange Risk Related to Customer Collateral*

A portion of performance bond deposits is denominated in various foreign currencies. We mark-to-market all deposits at least once each business day and require payment from clearing firms whose collateral has lost value due to changes in foreign currency rates and price. Therefore, our exposure to foreign currency risk related to performance bond deposits is considered minimal and is not expected to be material to our financial condition or operating results.

CME Group and its subsidiaries are referred to collectively as "the company" in the notes to the consolidated financial statements.

**2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES** 

**Basis of Presentation.** The accompanying consolidated financial statements are prepared in accordance with accounting principles generally accepted in the U.S. and include the accounts of the company and its subsidiaries. All intercompany transactions and balances have been eliminated.

**Use of Estimates.** The preparation of consolidated financial statements requires management to make estimates and assumptions that affect the reported amounts and the disclosure of contingent amounts on the consolidated financial statements and accompanying notes. Estimates are based on historical experience, where applicable, and assumptions management believes are reasonable under the circumstances. Due to the inherent uncertainty involved with estimates, actual results may differ.

**Cash and Cash Equivalents.** Cash and cash equivalents consist of cash and highly liquid investments with a maturity of three months or less at the time of purchase.

**Financial Investments.** The company maintains short-term and long-term investments, classified as equity method investments, available-for-sale debt securities, equity investments in privately-held entities and trading securities. Available-for-sale debt securities are carried at fair value, with unrealized gains and losses, net of deferred income taxes, reported as a component of accumulated other comprehensive income. Trading securities held in connection with non-qualified deferred compensation plans are recorded at fair value, with net realized and unrealized gains and losses and dividend income reported as investment income. For equity investments in privately-held entities that do not have a readily determinable fair value, our accounting policy is to utilize the measurement alternative for valuation of these investments, which permits the company to estimate fair value at cost minus impairment, plus or minus changes resulting from observable price movements. Additionally, the company maintains long-term investments accounted for under the equity method, which requires that the company recognize its share of net income (loss) and other comprehensive income (loss) in the investee as an adjustment to the carrying amount of the investment each reporting period.

The company reviews its investment portfolio at least quarterly, as well as whenever facts or circumstances exist which indicate that the carrying value of an investment is greater than its fair value. For investments not carried at fair value, the carrying value of the investment is reduced to its fair value and a corresponding impairment expense is charged to earnings, if events and circumstances indicate that a markdown to fair value is warranted. Declines in the fair value of available-for-sale debt securities that are deemed to represent indicators of impairment are charged to earnings as a realized loss.

**Fair Value of Financial Instruments.** The company uses a three-level classification hierarchy of fair value measurements that establishes the quality of inputs used to measure fair value. The fair value of a financial instrument is the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value of financial instruments is determined using various techniques that involve some level of estimation and judgment, the degree of which is dependent on the price transparency and the complexity of the instruments.

**Derivative Investments.** The company occasionally uses derivative instruments to limit exposure to changes in interest rates and foreign currency exchange rates Derivatives are recorded at fair value on the consolidated balance sheets. For those derivatives that meet the criteria for hedge accounting and are classified as effective cash flow hedges, changes in the fair value of derivative financial instruments are initially recorded in other comprehensive income and subsequently reclassified into earnings when the hedged item affects income. The company assesses, both at the inception of each hedge and on an ongoing basis, whether the derivative financial instruments that are designated as cash flow hedging transactions are highly effective in offsetting changes in cash flows of the hedged items. For any hedges no longer deemed effective or for which hedge accounting

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

is not applied, changes in fair value of the derivative instruments are recognized in earnings within other non-operating income (expense). There were no outstanding derivative instruments at December 31, 2025.

**Accounts Receivable.** Accounts receivable are comprised of trade receivables and unbilled revenue. All accounts receivable are stated at net realizable value. Exposure to losses on receivables for clearing and transaction fees and other amounts owed by clearing and trading firms is dependent on each firm's financial condition. With respect to clearing firms, our credit loss exposure is mitigated by the memberships that collateralize fees owed to the company. The company retains the right to liquidate exchange memberships to satisfy an outstanding receivable. The allowance for doubtful accounts is calculated based on management's assessment of future expected losses over the life of the receivable, historical trends and the current economic environment within which we operate.

**Performance Bonds and Guaranty Fund Contributions.** Performance bonds and guaranty fund contributions held for clearing firms may be in the form of cash, securities or other non-cash deposits.

Performance bonds and guaranty fund contributions received in the form of cash held by CME may be invested in U.S. government securities, U.S. government agency securities and certain foreign government securities acquired through and held by a bank or broker-dealer subsidiary of a bank, a cash account at the Federal Reserve Bank of Chicago, investments in highly rated government securities, money market funds or through CME's Interest Earning Facility (IEF) program. Any interest earned on these investments accrues to CME and is included in investment income on the consolidated statements of income. CME may distribute any interest earned on these investments to the clearing firms at its discretion. Because CME has control of the cash collateral and the benefits and market risks of ownership accrue to CME, cash performance bonds and guaranty fund contributions are reflected on the consolidated balance sheets. The cash performance bonds and guaranty fund contributions are considered restricted as the cash deposits cannot be used for the company's operations or to satisfy any operational liabilities. Cash performance bonds and guaranty fund contributions are included as restricted cash and restricted cash equivalents on the consolidated statements of cash flows.

Securities and other non-cash deposits may include U.S. Treasury securities, U.S. government agency securities, Eurobonds, corporate bonds, other foreign government securities, equity stocks and gold bullion. Securities and other non-cash deposits are held in safekeeping by a custodian bank. Interest and gains or losses on securities deposited to satisfy performance bond and guaranty fund requirements accrue to the clearing firm. Non-cash performance bonds can also include letters of credit. Because the benefits and risks of ownership accrue to the clearing firm, non-cash performance bonds and guaranty fund contributions are not reflected on the consolidated balance sheets.

**Property.** Property is stated at cost, less accumulated depreciation and amortization. Depreciation and amortization are calculated using the straight-line method, generally over one to twenty years. Property and equipment are depreciated over their estimated useful lives. Leasehold improvements are amortized over the shorter of the remaining term of the respective lease to which they relate or the remaining useful life of the leasehold improvement. Land is reported at cost. Internal and external costs incurred in developing, obtaining, or implementing computer software for internal use which meet the requirements for capitalization are amortized on a straight-line basis over the estimated useful life of the software, generally two to four years, but up to eight years for certain trading and clearing applications.

**Leases.** The company accounts for our leases of office space as operating leases. Landlord allowances are recorded as a direct reduction to the capitalized lease asset, which is reported in other assets and amortized to rent expense over the term of the lease. Both lease and direct non-lease costs are accounted for as a single lease component for purposes of capitalization on the consolidated balance sheets.The associated lease liability represents the present value of lease payments remaining in the lease term and is recorded within current and other liabilities depending upon the balance sheet classification of the payment obligations as short-term or long-term. For sale leaseback transactions, the company evaluates the sale and the lease arrangement based on the company's conclusion as to whether control of the underlying asset has been transferred and recognizes the sale leaseback as either a sale transaction or under the financing method, which requires the asset to remain on the consolidated balance sheets throughout the term of the lease and the proceeds to be recognized as a financing obligation. A portion of the lease payments is recognized as a reduction of the financing obligation and a portion is recognized as interest expense based on an imputed interest rate.

**Goodwill and Other Intangible Assets.** Goodwill represents the excess of the purchase price over the fair value of the net assets acquired in a business combination. The company reviews goodwill for impairment at least quarterly and whenever events or circumstances indicate that the carrying value may not be recoverable. The company may test goodwill quantitatively for impairment by comparing the carrying value of a reporting unit to its estimated fair value. Estimating the fair value of a reporting unit involves significant judgments inherent in the analysis, including estimating the amount and timing of future cash flows and the selection of appropriate discount rates and long-term growth rate assumptions. Changes in these estimates and assumptions could materially affect the determination of fair value for the reporting unit. If the carrying amount exceeds fair value, an impairment loss is recorded. In certain circumstances, goodwill may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

The company performs an impairment assessment of indefinite-lived intangible assets at least quarterly or whenever events or circumstances indicate that their carrying values may not be recoverable. If the indefinite-lived intangible asset carrying value exceeds its fair value, an impairment loss is recognized in an amount equal to that excess. Estimating the fair value of indefinite-lived intangible assets involves the use of valuation techniques that rely on significant estimates and assumptions, including forecasted revenue growth rates, forecasted allocations of expense and risk-adjusted discount rates. Changes in these estimates and assumptions could materially affect the determination of fair value for indefinite-lived intangible assets. In certain circumstances, indefinite-lived intangible assets may be reviewed qualitatively for indications of impairment without utilizing valuation techniques to estimate fair value.

Intangible assets subject to amortization are also assessed for impairment at least quarterly or when indicated by a change in economic or operational circumstances. The impairment assessment of these assets requires management to first compare the carrying value of the amortizing asset to undiscounted net cash flows. If the carrying value exceeds the undiscounted net cash flows, management is then required to estimate the fair value of the assets and record an impairment loss for the excess of the carrying value over the fair value. In connection with this impairment assessment, management also challenges the useful lives of our amortizing intangible assets.

**Business Combinations.** The company accounts for business combinations using the acquisition method. The method requires the acquirer to recognize the assets acquired, liabilities assumed, and any non-controlling interest in the acquiree at the acquisition date, measured at their fair values as of that date. The company may use independent valuation services to assist in determining the estimated fair values.

**Employee Benefit Plans.** The company recognizes the funded status of defined benefit postretirement plans on its consolidated balance sheets. Changes in that funded status are recognized in the year of change in other comprehensive income (loss). Plan assets and obligations are measured at year end. The company recognizes future changes in actuarial gains and losses and prior service costs in the year in which the changes occur through accumulated other comprehensive income (loss).

**Foreign Currency Translation and Re-measurement**. Foreign currency denominated monetary assets and liabilities are re-measured into the functional currency using period-end exchange rates. Gains and losses from foreign currency transactions and re-measurement of monetary assets and liabilities into the functional currency are included in other expense on the accompanying consolidated statements of income. When the functional currency differs from the reporting currency, revenues and expenses of foreign subsidiaries are translated from their functional currencies into U.S. dollars using weighted-average exchange rates while their assets and liabilities are translated into U.S. dollars using period-end exchange rates. Gains and losses resulting from foreign currency translations are included in accumulated other comprehensive income (loss) within shareholders' equity.

**Revenue Recognition.** Revenue recognition policies for specific sources of revenue are discussed below.

*Clearing and Transaction Fees.* Clearing and transaction fees include per-contract charges for trade matching, clearing, trading on the company's electronic trading platforms, portfolio reconciliation and compression services, risk mitigation, and other fees. Fees are charged at various rates based on the product traded, the method of trade, the exchange trading privileges of the customer making the trade and the type of contract. The majority of our clearing and transaction fees are recognized as revenue upon successful execution of the trade, which represents completion of our trade matching, novation and clearing activities. Therefore, unfilled or canceled buy and sell orders have no impact on revenue. On occasion, the customer's exchange trading privileges may not be properly entered by the clearing firm and incorrect fees are charged for the transactions. When this information is corrected within the time period allowed by the company, a fee adjustment is provided to the clearing firm. A reserve is established for estimated fee adjustments to reflect corrections to customer exchange trading privileges. The reserve is based on the historical pattern of adjustments processed as well as management's estimate of future adjustment activity. This reserve has historically been immaterial. The company believes the reserve is adequate to cover estimated adjustments as of December 31, 2025 and 2024.

*Market Data and Information Services.* Market data and information services represent revenue earned for the dissemination of market information. Revenues are accrued each month based on the number of devices reported by vendors or over a straight line basis in accordance with the market data subscription contract term. The company conducts periodic examinations of the number of devices reported and assesses additional fees as necessary. On occasion, customers will pay for services in a lump sum payment; however, revenue is recognized as services are provided.

*Other Revenues.* Other revenues include access and communication fees, fees for collateral management, equity membership subscription fees and fees for trade order routing through agreements from various strategic relationships as well as other services to customers. Revenue is recognized as services are provided.

*Concentration of Revenue.* One clearing firm represented 12% of the company's clearing and transaction fee revenue in 2025, one clearing firm represented 10% of the company's clearing and transaction fee revenue in 2024, but no clearing firms represented at least 10% of the company's clearing and transaction fee revenue in 2023. Should a clearing firm

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

withdraw from the company, management believes that the customer portion of that firm's trading activity would likely transfer to another clearing firm. Therefore, management does not believe that the company is exposed to significant risk from the ongoing loss of revenue received from a particular clearing firm.

The two largest resellers of market data represented approximately 30% of market data and information services revenue in 2025 and 2024, and approximately 32% in 2023. Should one of these vendors no longer subscribe to the company's market data, management believes that the majority of that firm's customers would likely subscribe to the market data through another reseller. Therefore, management does not believe that the company is exposed to significant risk from a loss of revenue received from any particular market data reseller.

**Share-Based Payments.** The company accounts for share-based payments at fair value, which is based on the grant date price of the equity awards issued. The company recognizes expense relating to stock-based compensation on an accelerated basis. As a result, the expense associated with each vesting date within a stock grant is recognized over the period of time that each portion of that grant vests. Forfeitures are recognized in the period in which they occur.

**Marketing Costs.** Marketing costs are incurred for the production and communication of advertising as well as other marketing activities. These costs are expensed when incurred, except for costs related to the production of broadcast advertising, which are expensed when the first broadcast occurs.

**Income Taxes.** Deferred income taxes arise from temporary differences between the tax basis and book basis of assets and liabilities. A valuation allowance is recognized if it is anticipated that some or all of a deferred tax asset may not be realized. The company accounts for uncertainty in income taxes recognized in its consolidated financial statements by using a more-likely-than-not recognition threshold based on the technical merits of the tax position taken or expected to be taken. The company recognizes interest and penalties related to uncertain tax positions in income tax expense.

**Segment Reporting.** The company reports the results of its operations as one operating segment primarily comprised of the businesses of CME, CBOT, NYMEX, COMEX and our cash markets business. The individual operations of the company do not meet the criteria for classification as separate reporting segments.

**Newly Adopted Accounting Policies.** In December 2023, the FASB issued an accounting standards update that requires public business entities to disclose in their tax rate reconciliation table additional categories of information about federal, state and foreign income taxes and to provide more details about the reconciling items in certain categories if they meet a quantitative threshold. It is also noted that this guidance requires all entities to disclose annually income taxes paid (net of refunds received) disaggregated by federal, state and foreign taxes and to disaggregate the information by jurisdiction based on a quantitative threshold. The Company adopted this standard on January 1, 2025, on a retrospective basis. Accordingly, prior periods have been adjusted to conform to the current period presentation. The adoption of this guidance resulted in expanded disclosures in our income tax footnote but did not impact our recognized income tax expense or cash taxes paid. See Note 9 – Income Taxes for further information.

**Recently Issued Accounting Pronouncements Not Yet Adopted.** In July 2025, the FASB issued an accounting standards update which provides a practical expedient when estimating the amount of expected credit losses on current accounts receivable and current contract assets. This update permits entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the current accounts receivable and current contract assets. Therefore, entities will not need to develop reasonable and supportable forecasts of future economic conditions. The practical expedient must be applied consistently across all current accounts receivable and current contract assets. This guidance is effective beginning in 2026, on an interim and annual basis, and must be adopted prospectively. Upon adoption, entities are required to disclose whether they have applied the practical expedient. Early adoption is permitted. Adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

In September 2025, the FASB issued an accounting standards update that clarifies and modernizes the accounting for costs related to internal-use software. The guidance removes all references to project stages and clarifies the threshold entities apply to begin capitalizing costs. With the removal of all references to project stages, the new guidance requires entities to begin capitalizing software costs when both of the following occur: (a) management, with the relevant authority, implicitly or explicitly authorizes and commits to funding a computer software project and (b) it is probable that the project will be completed and the software will be used to perform the function intended. The guidance specifies that the property, plant, and equipment disclosure requirements apply to capitalized software costs, regardless of how those costs are presented in the financial statements. The guidance is effective beginning in 2028, on an interim and annual basis. Entities may apply the guidance using a prospective, retrospective, or modified transition approach. Early adoption is permitted. Adoption of this guidance is not expected to have a material impact on our consolidated financial statements.

**3. REVENUE RECOGNITION**

The company generates revenue from customers from the following sources:

*Clearing and transaction fees.* Clearing and transaction fees include per-contract charges for trade matching, clearing, trading on the company's electronic trading platforms, portfolio reconciliation and compression services, risk mitigation, and other fees. Clearing and transaction fees are assessed upfront at the time of trade execution. As such, the company recognizes the majority of the fee revenue upon successful execution of the trade. The minimal remaining portion of the fee revenue related to settlement activities performed after trade execution is recognized over the short-term period that the contract is outstanding, based on management's estimates of the average contract lifecycle. These estimates are based on various assumptions to approximate the amount of fee revenue to be attributed to services performed through contract settlement, expiration, or termination. For cleared trades, these assumptions include the average number of days that a contract remains in open interest, contract turnover, average revenue per day, and revenue remaining in open interest at the end of each period.

The nature of contracts gives rise to several types of variable consideration, including volume-based pricing tiers, customer incentives associated with market maker programs and other fee discounts. The company includes fee discounts and incentives in the estimated transaction price when there is a basis to reasonably estimate the amount of the fee reduction. These estimates are based on historical experience, anticipated performance, and best judgment at the time. Because of the company's certainty in estimating these amounts, they are included in the transaction price of contracts.

*Market data and information services.* Market data and information services represent revenue from the dissemination of market data to subscribers, distributors, and other third-party licensees of market data. Pricing for market data is primarily based on the number of reportable devices used as well as the number of subscribers enrolled under the arrangement. Fees for these services are generally billed monthly. Market data services are satisfied over time and revenue is recognized on a monthly basis as the customers receive and consume the benefit of the market data services. However, the company also maintains certain annual license arrangements with one-time upfront fees. The fees for annual licenses are initially recorded as a contract liability and recognized as revenue monthly over the term of the annual period.

*Other.* Other revenues include certain access and communication fees, fees for collateral management, equity membership subscription fees, and fees for trade order routing through agreements from various strategic relationships. Access and communication fees are charged to customers that utilize various telecommunications networks and communications services. Fees for these services are generally billed monthly and the associated fee revenue is recognized as billed. Collateral management fees are charged to clearing firms that have collateral on deposit with the clearing house to meet their minimum performance bond and guaranty fund obligations on the exchange. These fees are calculated based on daily collateral balances and are billed monthly. This fee revenue is recognized monthly as billed as the customers receive and consume the benefits of the services. The company also has an equity membership program which provides equity members the option to pay a monthly subscription fee in satisfaction of their existing requirement to hold CME Group Class A common stock. Choosing to pay this fee in lieu of holding Class A shares is entirely voluntary and the client's choice. Fee revenue under this program is earned monthly as billed over the contractual term. Pricing for strategic relationships may be driven by customer levels and activity. There are fee arrangements which provide for monthly as well as quarterly payments in arrears. Revenue is recognized monthly for strategic relationship arrangements as the customers receive and consume the benefits of the services.

---

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, and customer advances and deposits (contract liabilities) on the consolidated balance sheets. Certain fees for transactions, annual licenses, and other revenue arrangements are billed upfront before revenue is recognized, which results in the recognition of contract liabilities. These liabilities are recognized on the consolidated balance sheets on a contract-by-contract basis upon commencement of services under the customer contract. These upfront customer payments are recognized as revenue over time as the obligations under the contracts are satisfied. Changes in the contract liability balances during 2025 were not materially impacted by any other factors. The balance of contract liabilities was $16.7 million and $15.6 million as of December 31, 2025 and 2024, respectively.

**4. PERFORMANCE BONDS AND GUARANTY FUND CONTRIBUTIONS**

The clearing house clears and guarantees the settlement of contracts traded in the futures and options and interest rate swap markets. In its guarantor role, the clearing house has precisely equal and offsetting claims to and from clearing firms on opposite sides of each contract, standing as an intermediary on every contract cleared. In the U.S., clearing firm funds are held according to Commodity and Futures Trading Commission (CFTC) regulatory account segregation standards. To the extent that funds are not otherwise available to satisfy an obligation under the applicable contract, the clearing house bears counterparty credit risk in the event that future market movements create conditions that could lead to clearing firms failing to meet their obligations to the clearing house. The clearing house reduces the exposure through risk management programs that include initial and ongoing financial standards for designation as a clearing firm, performance bond requirements, mark-to-market settlement cycles each business day, mandatory guaranty fund contributions and intra-day monitoring.

Each clearing firm is required to deposit and maintain balances in the form of cash, U.S. government securities, certain foreign government securities, bank letters of credit or other approved collateral to satisfy performance bond and guaranty fund requirements. All non-cash deposits and certain cash deposits with foreign currency exposure are marked-to-market and haircut each business day. Securities deposited by the clearing firms are not reflected on the consolidated financial statements and the clearing house does not earn any interest on these deposits. These balances may fluctuate significantly over time due to investment choices available to clearing firms and changes in the amount of contributions required. Cash performance bonds and guaranty fund contributions are included as restricted cash and restricted cash equivalents on the consolidated statements of cash flows.

The clearing house marks-to-market open positions at least once each business day (twice each business day for futures and options contracts), and requires payment from clearing firms whose positions have lost value and makes payments to clearing

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

firms whose positions have gained value. The clearing house has the capability to mark-to-market more frequently as market conditions warrant.

Under the extremely unlikely scenario of simultaneous default by every clearing firm who has open positions with unrealized losses, the maximum exposure at the time of default related to futures and options on futures positions would be one half of a business day of changes in fair value of all open positions, before considering the clearing house's ability to access defaulting clearing firms' collateral deposits. For cleared interest rate swap contracts, the maximum exposure at the time of default related to the clearing house's guarantee would be one full business day of changes in fair value of all open positions, before considering the clearing house's ability to access defaulting clearing firms' collateral. During 2025, the clearing house transferred an average of approximately $6.7 billion per business day through the clearing system for settlement from clearing firms whose positions had lost value to clearing firms whose positions had gained value. The clearing house reduces its exposure through maintenance performance bond requirements and guaranty fund contributions. For futures and options products, the clearing firms' collateral requirements are sized to cover at least one business day of anticipated price movements. For interest rate swap products, the clearing firms' collateral requirements are sized to cover at least five business days of anticipated price movements. Management has assessed the fair value of the company's settlement guarantee liability by taking the following factors into consideration: the design and operations of the clearing risk management process, the financial safeguard packages in place, historical evidence of default by a clearing member and the estimated probability of potential payouts by the clearing house. Based on the assessment performed, management estimates the guarantee liability to be nominal and therefore has not recorded any liability at December 31, 2025.

CME has been designated as a systemically important financial market utility by the Financial Stability Oversight Council and is authorized to maintain cash accounts at the Federal Reserve Bank of Chicago. At December 31, 2025 and 2024, the clearing house maintained $141.7 billion and $87.4 billion, respectively, within the cash accounts at the Federal Reserve Bank of Chicago. The cash deposited at the Federal Reserve Bank of Chicago is included within performance bonds and guaranty fund contributions on the consolidated balance sheets.

In 2025 and 2024, earnings from cash performance bond and guaranty fund contributions were $5,253.6 million and $3,943.8 million, respectively. In 2025 and 2024, expense related to the distribution of interest earned on collateral reinvestments were $4,842.5 million and $3,669.4 million, respectively. The earnings from cash performance bonds and guaranty fund contributions are included in investment income and the expense related to the distribution of interest earned is included in other non-operating income (expense) on the consolidated statements of income.

CME and The Options Clearing Corporation (OCC) have a perpetual cross-margin arrangement, whereby a clearing firm may maintain a cross-margin account in which a clearing firm's positions in certain equity index futures and options are combined with certain positions cleared by OCC for purposes of calculating performance bond requirements. The performance bond deposits are held jointly by CME and OCC. Cross-margin cash, securities and letters of credit jointly held with OCC under the cross-margin agreement are reflected at 50% of the total, or CME's proportionate share per that agreement. If a participating firm defaults, the gain or loss on the liquidation of the firm's open position and the proceeds from the liquidation of the cross- margin account would be allocated equally between CME and OCC. In the event of a remaining loss, CME would first apply assets of the defaulting clearing firm to satisfy its payment obligation. These assets include the defaulting firm's guaranty fund contributions, performance bonds and any other available assets, such as assets required for clearing membership and any associated trading rights. Thereafter, if the payment default remains unsatisfied, the clearing house would use its corporate contributions designated for the respective financial safeguard package. The clearing house would then use guaranty fund contributions of other clearing firms within the respective financial safeguard package and funds collected through an assessment against solvent clearing firms within the respective financial safeguard package to satisfy the deficit.

In addition, CME has a cross-margin arrangement with Fixed Income Clearing Corporation (FICC) whereby a clearing firm may be subject to reduced margin requirements for certain of its offsetting positions. Clearing firms maintain separate performance bond deposits with each clearing house, but based on the net offsetting positions between CME and FICC, each clearing house may reduce that firm's performance bond requirements. If a participating firm defaults, the gain or loss on the liquidation of the firm's open positions and the proceeds from the liquidation of the cross margin account would be allocated between CME and FICC pursuant to a publicly-available cross-margining agreement. In the event of a remaining loss, CME would first apply assets of the defaulting clearing firm to satisfy its payment obligation. These assets include the defaulting firm's guaranty fund contributions, performance bonds and any other available assets, such as assets required for clearing membership and any associated trading rights. Thereafter, if the payment default remains unsatisfied, the clearing house would use its corporate contributions designated for the respective financial safeguard package. The clearing house would then use guaranty fund contributions of other clearing firms within the respective financial safeguard package and funds collected through an assessment against solvent clearing firms within the respective financial safeguard package to satisfy the deficit.

Each clearing firm for futures and options is required to deposit and maintain specified guaranty fund contributions in the form of cash or U.S. Treasury securities (base guaranty fund). In the event that performance bonds, guaranty fund contributions and other assets required to support clearing membership of a defaulting clearing firm are inadequate to fulfill that clearing firm's outstanding financial obligation, the base guaranty fund for contracts other than interest rate swaps is available to cover

potential losses after first utilizing $100.0 million of corporate contributions designated by CME to be used in the event of a default of a clearing firm for the base guaranty fund.

The clearing house maintains a separate guaranty fund to support the clearing firms that clear interest rate swap products (cleared interest rate swaps contract guaranty fund). The funds for interest rate swaps are independent of the base guaranty fund and are isolated to clearing firms for products in the respective asset class. Each clearing firm for cleared interest rate swaps is required to deposit and maintain specified guaranty fund contributions in the form of cash or U.S. Treasury securities. In the event that performance bonds, guaranty fund contributions and other assets required to support clearing membership of a defaulting clearing firm for cleared interest rate swap contracts are inadequate to fulfill that clearing firm's outstanding financial obligation, the interest rate swaps contracts guaranty fund is available to cover potential losses after first utilizing $150.0 million of corporate contributions designated by CME to be used in the event of a default of a cleared interest rate swap clearing firm.

CME maintains a 364-day multi-currency line of credit with a consortium of domestic and international banks to be used in certain situations by the clearing house. CME may use the proceeds to provide temporary liquidity in the unlikely event of a clearing firm default, in the event of a liquidity constraint or default by a depositary (custodian of the collateral), or in the event of a temporary disruption with the domestic payments system that would delay payment of settlement variation between CME and its clearing firms. Clearing firm guaranty fund contributions received in the form of cash or U.S. Treasury securities as well as the performance bond assets of a defaulting firm can be used to collateralize the facility. The line of credit provides for borrowings of up to $7.0 billion. At December 31, 2025, guaranty fund contributions available to collateralize the facility were $10.7 billion. CME has the option to request an increase in the line from $7.0 billion to $10.0 billion, subject to the approval of participating banks. In addition to the 364-day fully secured, committed multi-currency line of credit, the company also has the option to use the $2.3 billion multi-currency revolving senior credit facility to provide liquidity for the clearing house in the unlikely event of default.

The company maintains committed repurchase facility agreements amounting to a total of $1.0 billion. The committed repurchase facilities provide access to cash, secured by non-cash collateral, in the event that one or more of our clearing firms fails to promptly discharge an obligation to the clearing house. The facilities are subject to annual renewal. The company currently does not have any borrowings outstanding under these facilities.

CME also maintains a committed facility of up to $750.0 million for foreign currency conversions. The committed foreign currency facility allows the clearing house to convert cash to another currency within generally accepted local market timeframes in the event that one or more of our clearing firms fails to promptly discharge an obligation to the clearing house. The facility is subject to annual renewal. The company currently does not have any foreign currency trades outstanding under this facility.

The clearing house is required under the U.S. Commodity Exchange Act to segregate cash and securities deposited by clearing firms from its clearing member customers. In addition, the clearing house requires segregation of all funds deposited by its clearing firms from operating funds.

A valuation allowance is recorded when it is more-likely-than-not that some portion or all of the deferred income tax assets may not be realized. The ultimate realization of the deferred income taxes depends on the ability to generate sufficient taxable income of the appropriate character in the future and in the appropriate taxing jurisdictions.

At December 31, 2025, the company had domestic income tax loss carryforwards of $21.3 million of which $19.3 million will expire between 2030 and 2036 and $2.0 million can be carried forward indefinitely. These amounts primarily relate to losses from the acquisition of NEX Group plc and the acquisition of Pivot, Inc. At December 2025, the company determined that it was more-likely-than-not that certain foreign deferred income tax assets will be fully realized. No valuation allowance was recorded at December 31, 2025 and 2024.

**10. EMPLOYEE BENEFIT PLANS**

**Pension Plans.** CME maintains a non-contributory defined benefit cash balance pension plan for eligible employees. CME's plan provides for a pay-based credit added to the cash balance account based on age and earnings and includes salary and cash bonuses in the definition of earnings. Employees who have completed a continuous 12-month period of employment and have reached the age of 21 are eligible to participate. Participant cash balance accounts receive an interest credit equal to the greater of the one-year constant maturity yield for U.S. Treasury notes or 4.0%. Participants become vested in their accounts after three years of service. The measurement date used for the plan is December 31.

The following is a summary of the change in projected benefit obligation:

---

| | | |
|:---|:---|:---|
| **(in millions)** | **2025** | **2024** |
| Balance at January 1 | $364.0 | $351.5 |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Benefits paid | (16.4) | (18.4) |
| Balance at December 31 | $397.2 | $364.0 |

The aggregate accumulated benefit obligation was $366.4 million and $335.6 million at December 31, 2025 and 2024, respectively.

The following is a summary of the change in fair value of plan assets:

---

| | | | |
|:---|:---|:---|:---|
| **(in millions)** | **2025** | **2024** | **2023** |
| Balance at January 1 | $367.5 | $350.8 | $331.7 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Actual return on plan assets | 51.5 | 26.1 | 38.9 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Employer contributions |  | 9.0 | 3.0 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Benefits paid | (16.4) | (18.4) | (22.8) |
| Balance at December 31 | $402.6 | $367.5 | $350.8 |

---

The plan assets are classified into a fair value hierarchy in their entirety based on the lowest level of input that is significant to each asset or liability's fair value measurement. Valuation techniques for level 2 assets use significant observable inputs such as quoted prices for similar assets, quoted market prices in inactive markets and other inputs that are observable or can be supported by observable market data.

The fair value of each major category of plan assets as of December 31, 2025 and 2024 is indicated below:

---

| | | |
|:---|:---|:---|
| **(in millions)** | **2025** | **2024** |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Foreign equity | 56.8 | 46.2 |
| Total | $402.6 | $367.5 |

---

At December 31, 2025 and 2024, the fair value of pension plan assets exceeded the pension benefit obligation by $5.4 million and $3.5 million, respectively, and the excess was recorded as a non-current pension asset in other assets.

CME's funding goal is to have its pension plan 100% funded at each year-end on a projected benefit obligation basis, while also satisfying any minimum required contribution and obtaining the maximum tax deduction. Year-end 2025 assumptions have been used to project the assets and liabilities from December 31, 2025 to December 31, 2026. The company anticipates based on this projection that an additional contribution of $10.1 million in 2026 will be necessary for it to meet its funding goal. However, the amount of the actual contribution is contingent on various factors, including the actual rate of return on the plan assets during 2026 and the December 31, 2026 discount rate.

The components of net pension expense and the assumptions used to determine the end-of-year projected benefit obligation and net pension expense in aggregate at December 31, 2025, 2024 and 2023 are indicated below:

---

| | | | |
|:---|:---|:---|:---|
| **(in millions)** | **2025** | **2024** | **2023** |
| Components of Net Pension Expense: |  |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Service cost | $22.2 | $21.9 | $21.1 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest cost | 21.3 | 18.8 | 18.5 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Expected return on plan assets | (25.6) | (24.1) | (21.6) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Recognized net actuarial loss |  | 0.4 | 0.3 |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Discount rate | 5.70% | 5.20% | 5.60% |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Rate of compensation increase | 4.00 | 4.00 | 4.00 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Expected return on plan assets | 7.25 | 7.25 | 6.75 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest crediting rate | 4.20 | 5.14 | 4.75 |

---

The discount rate for the plan was determined based on the market value of a theoretical settlement bond portfolio. This portfolio consisted of U.S. dollar denominated Aa-rated corporate bonds across the full maturity spectrum. A single equivalent discount rate was determined to align the present value of the required cash flow with that settlement value. The resulting discount rate was reflective of both the current interest rate environment and the plan's distinct liability characteristics.

The basis for determining the expected rate of return on plan assets for the plan is comprised of three components: historical returns, industry peers and forecasted return. The plan's total return is expected to equal the composite performance of the security markets over the long term. The security markets are represented by the returns on various domestic and international stock, bond and commodity indexes. These returns are weighted according to the allocation of plan assets to each market and measured individually.

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

The overall objective of the plan is to achieve required long-term rates of return in order to meet future benefit payments. The component of the investment policy for the plan that has the most significant impact on returns is the asset mix. The asset mix has a minimum and maximum range depending on asset class. The plan assets are diversified to minimize the risk of large losses by any one or more individual assets. Such diversification is accomplished, in part, through the selection of asset mix and investment management. The asset allocation for the plan, by asset category, at December 31, 2025 and 2024 was as follows:

---

| | | |
|:---|:---|:---|
| | **2025** | **2024** |
| Fixed income | 47.1% | 45.7% |
| U.S. equity | 37.0 | 37.4 |
| Foreign equity | 14.1 | 12.6 |
| Money market funds | 1.8 | 4.3 |

---

For 2026, management expects the fixed income asset class to be approximately 50% of the portfolio. The target allocation for the equity asset classes is expected to be approximately 50% of the portfolio.

At times, the company may determine that it is necessary to place some assets in cash equivalent investments in order to pay expected plan liabilities. Given this, the actual asset allocation for the plan may not fall within the target allocation ranges from time to time.

According to the plan's investment policy, the plan is not allowed to invest in securities that compromise independence, short sales of securities directly owned by the plan, securities purchased on margin or other uses of borrowed funds, derivatives not used for hedging purposes, restricted stock or illiquid securities or any other transaction prohibited by employment laws. If the plan directly invests in short-term and long-term debt obligations, the investments are limited to obligations rated at the highest rating category by Standard & Poor's or Moody's.

The pre-tax balance and activity of actuarial losses for the pension plan, which are included in other comprehensive income (loss), for 2025 are as follows:

---

| | |
|:---|:---|
| **(in millions)** | **Actuarial<br>Loss** |
| Balance at January 1 | $20.8 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Unrecognized net loss (gain) for the period | (19.8) |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Recognized as a component of net pension expense |  |
| Balance at December 31 | $1.0 |

---

At December 31, 2025, anticipated benefit payments from the plan in future years are as follows:

---

| | |
|:---|:---|
| **(in millions)** | |
| 2026 | $37.8 |
| 2027 | 38.0 |
| 2028 | 38.9 |
| 2029 | 39.8 |
| 2030 | 40.6 |
| 2031-2035 | 205.6 |

---

**Savings Plans.** CME maintains a defined contribution savings plan pursuant to Section 401(k) of the Internal Revenue Code, whereby all U.S. employees are participants and have the option to contribute to this plan. CME matches employee contributions up to 3% of the employee's base salary and may make additional discretionary contributions.

In addition to the plan for U.S. employees, the company maintains defined contribution savings plans for employees in international locations.

Aggregate expense for all of the defined contribution savings plans amounted to $22.0 million, $20.8 million and $19.7 million in 2025, 2024 and 2023, respectively.

**CME Non-Qualified Plans.** CME maintains non-qualified plans, under which participants may make assumed investment choices with respect to amounts contributed on their behalf. Although not required to do so, CME invests such contributions in assets that mirror the assumed investment choices. The balances in these plans are subject to the claims of general creditors of the company and totaled $116.3 million and $104.2 million at December 31, 2025 and 2024, respectively. Although the value of the plans is recorded as an asset in marketable securities on the consolidated balance sheets, there is an equal and offsetting

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

liability. The investment results of these plans have no impact on net income as the investment results are recorded in equal amounts to both investment income and compensation and benefits expense. The non-qualified plans include the following:

*Supplemental Savings Plan.* CME maintains a supplemental plan to provide benefits for employees who have been impacted by statutory limits under the provisions of the qualified pension and savings plan. Employees in this plan are subject to the vesting requirements of the underlying qualified plans.

*Deferred Compensation Plan.* A deferred compensation plan is maintained by CME, under which eligible employees and members of the board of directors may contribute a percentage of their compensation and defer income taxes thereon until the time of distribution.

**11. LEASES**

**Leases.** The company has operating leases for datacenters and corporate offices. The operating leases have remaining lease terms of up to 12 years, some of which include options to extend or renew the leases for up to an additional five years, and some of which include options to early terminate the leases in less than 12 months. Management evaluates the exercisability of these options at least quarterly in order to determine whether the contract term must be reassessed. For a small number of the leases, primarily the international locations, management's approach is to enter into short-term leases for a lease term of 12 months or less in order to provide for greater flexibility in the local environment. For certain office spaces, the company has entered into arrangements to sublease excess space to third parties, while the original lease contract remains in effect with the landlord.

The company also has one finance lease, which is related to the sale of our datacenter in March 2016. In connection with the sale, the company leased back a portion of the property. The sale leaseback transaction was recognized under the financing method and not as a sale leaseback arrangement.

The right-of-use lease asset is recorded within other assets, and the present value of the lease liability is recorded within other liabilities (segregated between short-term and long-term) on the consolidated balance sheets. The discount rate applied to the lease payments represents the company's incremental borrowing rate. The company has elected to utilize the short-term lease exception as prescribed in the leasing standard, such that the company has not capitalized on the balance sheet a lease asset or lease liability for leasing arrangements with a contractual term of 12 months or less from the lease commencement date.

The components of lease costs were as follows for the years ended December 31, 2025 and 2024:

**12. CONTINGENCIES**

*Legal and Regulatory Matters.* In the normal course of business, the company discusses matters with its regulators raised during regulatory examinations or otherwise subject to their inquiry and oversight. These matters could result in censures, fines, penalties or other sanctions. Management believes the outcome of any resulting actions will not have a material impact on the company's consolidated financial position or results of operations. However, the company is unable to predict the outcome or the timing of the ultimate resolution of these matters, or the potential fines, penalties or injunctive or other equitable relief, if any, that may result from these matters.

A putative class action complaint was filed January 15, 2014 in the Circuit Court of Cook County, Chancery Division, against CME Group Inc. and the Board of Trade of the City of Chicago, Inc. The plaintiffs, certain Class B shareholders of CME Group and Class B members of CBOT, allege breach of contract and breach of the implied covenant of good faith and fair dealing for violations of their core rights granted in the defendants' respective Certificates of Incorporation. On December 2, 2021, the court granted the plaintiffs' motion for certification of a damages-only class. In early 2024, the defendants moved for summary judgment on all claims. On April 16, 2025, the court granted the motion in part and denied the motion in part, and set the remaining claims for a jury trial. After a three week trial, on July 25, 2025, the jury returned a unanimous verdict in favor of the defendants on all counts. Plaintiffs have filed a post-trial motion seeking a new trial, and we expect the plaintiffs to appeal the verdict should the post-trial motions be denied.

In addition, the company is a defendant in, and has potential for, various other legal proceedings arising from its regular business activities. While the ultimate results of such proceedings against the company cannot be predicted with certainty, the company believes that the resolution of any of these matters on an individual or aggregate basis will not have a material impact on its consolidated financial position or results of operations. No accrual was required for contingent legal and regulatory matters as none were probable and estimable as of December 31, 2025 and 2024.

*Intellectual Property Indemnifications.* Certain agreements with customers and other third parties related to accessing the CME Group platforms, utilizing market data services and licensing CME SPAN and SPAN 2 software may contain indemnifications from intellectual property claims that may be made against them as a result of their use of the applicable products and/or services. The potential future claims relating to these indemnifications cannot be estimated and therefore no liability has been recorded.

**13. GUARANTEES**

*Mutual Offset Agreement.* CME and Singapore Exchange Limited (SGX) maintain a mutual offset agreement with a current term through April 2027. This agreement enables market participants to open a futures position on one exchange and liquidate it on the other. The term of the agreement will automatically renew for a two-year period after April 2027 unless either party provides advance notice of its intent to terminate. CME can maintain collateral in the form of irrevocable standby letters of credit. At December 31, 2025, CME was contingently liable to SGX on irrevocable letters of credit totaling $400.0 million. CME also maintains a $350.0 million line of credit to meet its obligations under this agreement. Regardless of the collateral, CME guarantees all cleared transactions submitted through SGX and would initiate procedures designed to satisfy these financial obligations in the event of a default, such as the use of performance bonds and guaranty fund contributions of the defaulting clearing firm. Management has assessed the fair value of the company's guarantee liability under this mutual offset agreement by taking the following factors into consideration: the design and operations of the clearing risk management process, the financial safeguard packages in place, historical evidence of default by a clearing firm and the estimated probability of potential payouts by the clearing house. Based on the assessment performed, management estimates the guarantee liability to be nominal and therefore has not recorded any liability at December 31, 2025.

*Family Farmer and Rancher Protection Fund.* In 2012, the company established the Family Farmer and Rancher Protection Fund (the Fund). The Fund is designed to provide payments, up to certain maximum levels, to family farmers, ranchers and other agricultural industry participants who use the company's agricultural products and who suffer losses to their segregated account balances due to their CME clearing member becoming insolvent. Under the terms of the Fund, farmers and ranchers are eligible for up to $25,000 per participant. Farming and ranching cooperatives are eligible for up to $100,000 per cooperative. The Fund has an aggregate maximum payment amount of $100.0 million. Since its establishment, the Fund has made payments of approximately $2.0 million, which leaves $98.0 million available for future claims. If payments to participants were to exceed this amount, payments would be pro-rated. Clearing firms and customers must register in advance with the company and provide certain documentation in order to substantiate their eligibility. The company believes that its guarantee liability is nominal and therefore has not recorded any liability at December 31, 2025.

**Preferred Stock.** CME Group has approximately 4.6 million shares of Series G Non-Voting Convertible Preferred Stock (Series G preferred stock) outstanding. The Series G preferred stock is non-voting and is convertible into Class A common stock at a specified conversion rate, which is initially 1:1. The Series G preferred stock ranks on a parity basis with the Class A common stock with respect to dividend and liquidation rights and therefore participates in the earnings and losses of CME Group on the same basis as Class A common stock.

**Associated Trading Rights.** Members of CME, CBOT, NYMEX and COMEX own or lease trading rights which entitle them access to open outcry trading, discounts on trading fees and the right to vote on certain matters as provided for by the rules of the particular exchange and CME Group's or the subsidiary's organizational documents. Each class of CME Group Class B common stock is associated with a membership in a specific division for trading at CME. A CME trading right is a separate asset that is not part of or evidenced by the associated share of Class B common stock of CME Group. The Class B common stock of CME Group is intended only to ensure that the Class B shareholders of CME Group retain rights with respect to the election of six members to the board of directors and approval rights with respect to the core rights described below.

Trading rights at CBOT are evidenced by Class B memberships in CBOT, at NYMEX by Class A memberships in NYMEX and at COMEX by COMEX Division Memberships. Members of CBOT, NYMEX and COMEX do not have any rights to elect members of the board of directors and are not entitled to receive dividends or other distributions on their memberships or trading permits.

**Core Rights.** Holders of CME Group Class B common shares have the right to approve changes in specified rights relating to the trading privileges at CME associated with those shares. These core rights relate primarily to trading right protections, certain trading fee protections and certain membership benefit protections. Votes on changes to these core rights are weighted by class. Each class of Class B common stock has the following number of votes on matters relating to core rights: Class B-1, six votes per share; Class B-2, two votes per share; Class B-3, one vote per share; and Class B-4, 1/6th of one vote per share. The approval of a majority of the votes cast by the holders of shares of Class B common stock is required in order to approve any changes to core rights. Holders of shares of Class A common stock do not have the right to vote on changes to core rights.

**Voting Rights.** With the exception of the matters reserved to holders of CME Group Class B common stock, holders of CME Group common stock vote together on all matters for which a vote of common shareholders is required. In these votes, each holder of shares of Class A or Class B common stock of CME Group has one vote per share. The holder of Series G preferred stock does not have any voting rights.

**Transfer Restrictions.** Each class of CME Group Class B common stock is subject to transfer restrictions contained in the Certificate of Incorporation of CME Group. These transfer restrictions prohibit the sale or transfer of any shares of Class B common stock separate from the sale of the associated trading rights.

**15. STOCK-BASED PAYMENTS**

CME Group adopted an Omnibus Stock Plan under which stock-based awards may be made to employees. A total of 40.2 million Class A shares have been reserved for awards under the plan. Awards totaling 26.2 million shares have been granted and are outstanding or have been exercised under the plan as of December 31, 2025. Awards granted generally vest over a four-year period, with 25% vesting one year after the grant date and on that same date in each of the following three years.

Total compensation expense for all stock-related awards (including ESPP) and total income tax benefit recognized on the consolidated statements of income for these awards at December 31, 2025, 2024 and 2023 were as follows:

---

| | | | |

At December 31, 2025, there was $148.6 million of total unrecognized compensation expense related to employee stock-based compensation arrangements that had not yet vested. The total unrecognized expense is expected to be recognized over a weighted average period of 2.2 years.

In 2025, the company granted 304,784 shares of restricted Class A common stock and restricted stock units with respect to 11,072 shares of Class A common stock. Restricted common stock and restricted stock units generally have a vesting period of two to four years. The fair value related to these grants was $81.8 million, which is recognized as compensation expense on an accelerated basis over the vesting period. Dividends are accrued on restricted Class A common stock and restricted stock units and are paid once the restricted stock vests. In 2025, the company also granted 71,420 performance shares. The fair value related to these grants was $22.5 million, which is recognized as compensation expense on a straight-lined basis over the vesting period. The vesting of these shares is contingent on meeting stated performance or market conditions, generally measured over a three-year period.

Under the ESPP, eligible employees may acquire shares of Class A common stock using after-tax payroll deductions made during consecutive offering periods of approximately six months in duration. Shares are purchased at the end of each offering period at a price of 90% of the closing price of the Class A common stock as reported on the Nasdaq Global Select Market. Compensation expense is recognized on the dates of purchase for the discount from the closing price. In 2025, 2024 and 2023, a total of 32,304, 37,466 and 40,960 shares, respectively, of Class A common stock were issued to participating employees. These shares are subject to a six-month holding period. Annual expense of $0.9 million, $0.8 million, and $0.8 million for the purchase discount was recognized in 2025, 2024 and 2023, respectively.

Non-executive directors receive an annual award of Class A common stock with a value equal to $145,000. Non-executive directors could also elect to receive some or all of the cash portion of their annual stipend, up to $95,000, in shares of stock based on the closing price at the date of distribution. As a result, 10,964 shares, 18,901 shares and 19,966 shares of Class A common stock were issued to non-executive directors during 2025, 2024 and 2023, respectively. These shares are not subject to any vesting restrictions.

**17. FAIR VALUE MEASUREMENTS**

The company uses a three-level classification hierarchy of fair value measurements for disclosure purposes:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 1 inputs, which are considered the most reliable evidence of fair value, consist of quoted prices (unadjusted) for identical assets or liabilities in active markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 2 inputs consist of observable market data, such as quoted prices for similar assets and liabilities in active markets, or inputs other than quoted prices that are directly observable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Level 3 inputs consist of unobservable inputs which are derived and cannot be corroborated by market data or other entity-specific inputs.

The company's level 1 assets generally include investments in publicly traded mutual funds, equity securities and corporate debt securities with quoted market prices. In general, the company uses quoted prices in active markets for identical assets to determine the fair value of marketable securities.

The company's level 2 assets and liabilities generally consist of long-term debt notes. The fair values of the long-term debt notes were based on quoted market prices in an inactive market.

The company's level 3 assets and liabilities include certain investments that were adjusted to fair value.

**18. SEGMENT REPORTING**

The company's business is conducted through one reportable business segment, CME Group consolidated. The company has one operating segment as this is the level at which resource allocation and operating decisions regarding company performance are evaluated and determined by the senior leadership team.

The company's chief operating decision maker (CODM) is the senior leadership team that includes the Chairman and Chief Executive Officer, Chief Information Officer, Senior Managing Director Global Head of Fixed Income, President and Chief Financial Officer, Senior Managing Director and General Counsel, Senior Managing Director Global Head Equities, FX, and Alternative Products, Chief Human Resources Officer, Senior Managing Director Global Head of Commodities Markets, Chief Operating Officer and Global Head of Clearing, Chief Transformation Officer, and Chief Commercial Officer. The members of the senior leadership team represent a cross-functional group of management, which evaluates the company's operating results in order to evaluate performance and make decisions about the company's operating matters.

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

The CODM reviews the financial results of CME Group consolidated on an ongoing basis throughout the year. As a single segment, the segment profitability measure is consolidated net income. Consolidated net income informs key operating decisions as made by the CODM, which include bonus allocation, discretionary share-based awards, liquidity and cash needs, new product development, existing product expansion, and product discontinuation. Consolidated net income is deemed the best indicator of segment performance. Segment assets are not reported to, or used by, the CODM to allocate resources or to assess performance.

The CODM evaluates current period consolidated net income performance as compared to prior periods, budgeted results, and forecasts. The CODM reviews consolidated revenues as disaggregated by the following: clearing and transaction fees as a combination of rate per contract and average daily volume for each major asset class, market data fee revenue, and other revenue. The significant expense categories are consistent with those presented on the face of the consolidated statements of income. The components of non-operating income are also reviewed by the CODM. It is noted that the level of financial information provided to the CODM is consistent with the financial statement line items as disclosed in our consolidated statements of income.

The table below presents geographic locations with material revenue for the years ended December 31, 2025, 2024 and 2023 and geographic locations with material long-lived assets as of December 31, 2025 and 2024. Locations with revenue or long lived assets representing 10% or more of total revenue or long lived assets are considered to have material revenue or long lived assets.

**19. EARNINGS PER SHARE**

The company uses the two-class method to calculate basic and diluted earnings per common share because its Series G preferred stock are participating securities. Under the two-class method, undistributed earnings are allocated to common stock and participating securities according to their respective rights in undistributed earnings, as if all of the earnings for the period had been distributed. Basic earnings per common share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding during the period. Net income attributable to common shareholders is reduced for preferred stock dividends earned during the period. Series G preferred stock also receives a proportionate allocation of undistributed or overdistributed earnings for the period because Series G preferred stock has a contractual obligation to share in profits and losses of the company. Diluted earnings per share is computed by dividing the net income attributable to common shareholders by the weighted average number of common shares outstanding plus potentially dilutive common shares.

Anti-dilutive stock awards were as follows for the years presented:

Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control system has been designed to provide reasonable assurance to management and the board of directors regarding the preparation and fair presentation of published financial statements.

Management assessed the effectiveness of the company's internal control over financial reporting as of December 31, 2025.

**Report of Independent Registered Public Accounting Firm**

To the Shareholders and the Board of Directors of CME Group Inc.

**Opinion on the Financial Statements** 

We have audited the accompanying consolidated balance sheets of CME Group Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated February 26, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

**Critical Audit Matter**

| *Description of the Matter* | As discussed in Note 9 to the consolidated financial statements, the Company had unrecognized income tax benefits of $294.8 million related to uncertain tax positions as of December 31, 2025. Uncertainty in a tax position may arise due to the application of complex tax regulations, among other considerations. In its accounting for uncertain tax positions the Company used significant judgment to (1) determine whether, based on the technical merits, the tax position is more likely than not to be sustained upon examination and (2) measure the amount of the tax benefit that qualifies for recognition. <br>Auditing management's estimate of the Company's uncertain tax positions that qualified for recognition was especially challenging because management's estimate involved significant judgment in evaluating the technical merits of the positions, including interpretations of applicable tax laws and regulations, as well as in measuring the amount of the tax benefit that qualifies for recognition.  |
| *How We Addressed the Matter in Our Audit* | We tested the Company's controls that address the risk of material misstatement relating to the recognition and measurement of uncertain tax positions. For example, we tested controls over the Company's assessment of the technical merits of tax positions and management's process to measure the benefit of those tax positions that qualified for recognition, including management's review of the inputs used in the calculations. <br>We also involved our tax professionals to evaluate the Company's uncertain tax positions. Our audit procedures included, among others, evaluating the assumptions the Company used to develop and measure its uncertain tax positions that qualified for recognition, as well as testing the completeness and accuracy of the underlying data used by management. We also assessed the technical merits and measurement of the Company's uncertain tax positions by evaluating evolving interpretations of the tax regulations, together with the Company's relevant correspondence with tax authorities and third-parties, which were used by the Company to recognize and measure its uncertain tax positions.  |

**Report of Independent Registered Public Accounting Firm**

To the Shareholders and the Board of Directors of CME Group Inc.

**Opinion on Internal Control Over Financial Reporting**

We have audited CME Group Inc. and subsidiaries' internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, CME Group Inc. and subsidiaries (the Company) maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income, comprehensive income, equity and cash flows for each of the three years in the period ended December 31, 2025, and the related notes and financial statement schedule listed in the Index at Item 15(a)(2) and our report dated February 26, 2026 expressed an unqualified opinion thereon.

**Basis for Opinion**

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management's Annual Report on Internal Control Over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

**Definition and Limitations of Internal Control Over Financial Reporting**

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

**ITEM 1C.&nbsp;&nbsp;&nbsp;&nbsp;CYBERSECURITY**

As a highly regulated global financial services company, we understand the substantial operational risks for companies in our industry as well as the importance of protecting the information and data of our clients, third parties and employees and the resilience of our systems. As such, our Global Informational Security (GIS) Program is designed and operated to mitigate information security risks and threats to the company. Its intent is to safeguard the confidentiality, integrity and availability of our information and services. The GIS Program is designed to strengthen the integrity of the global markets we support, protect CME Group's information assets, maintain client, third party and employee trust, support our pursuit of strategic objectives, contribute to shareholder value and preserve our reputation and brand. We implement technical, physical and administrative safeguards to protect the confidential and sensitive information of our clients, third parties, employees and other information under CME Group's stewardship. We manage cybersecurity risk to the organization as part of our business strategy, risk management and financial functions in alignment with our overall Enterprise Risk Management Program and regularly engage with the risk committee of the board of directors and the board of directors as a whole regarding the effectiveness of the GIS Program and the management of our cybersecurity risks.

The GIS Program is led by CME Group's Chief Information Security Officer (CISO), who has worked in various roles in information security for over 20 years and has led our GIS Program for more than five years since joining the company in 2016 in a senior role in GIS. The CISO reports to our Chief Information Officer (CIO), a member of our Management Team. Our GIS team is comprised of over 200 full-time employees, many of whom hold cybersecurity, risk, or management certifications, such as Certified Information Systems Security Professional, Certified Information Security Manager, Certified in Risk and Information Systems Control, Series 99, Certified Information Systems Auditor, Project Management Professional, various cloud provider certifications and various levels of ITIL certifications. As part of our GIS Program, CME Group operates a Cyber Defense Center that virtually links 24/7 to our international cybersecurity teams and serves as a global hub for cybersecurity risk management activities, including log collection, event monitoring, threat detection and incident response, resiliency, operations, vulnerability management and the proactive collection and processing of both open source and proprietary threat and intelligence feeds allowing the company to efficiently manage, investigate and respond to cybersecurity events. Our GIS team conducts analyses and aims to prevent, detect and respond to systemic events that might threaten our company, industry or the economy.

The GIS Program includes a Cyber Defense team, which manages the Incident Response Plan (IRP), and consists of subject matter experts from GIS and Information Governance, who work together to monitor and respond to cybersecurity incidents. The IRP outlines our cyber and incident response policies and governs our incident response lifecycle, which divides overall incident response into serial phases. The Crisis Management Team (CMT) is responsible for oversight during an incident, in conjunction with the Cyber Coordination Team (CCT). The CCT manages responses to cybersecurity and compliance incidents, collaborating with subject matter experts from various departments in response to specific incidents. When an incident reaches a certain threshold of severity, our CISO and CIO escalate the matter to our Chief Operating Officer, who is another member of our Management Team, to determine next steps, as well as possible customer and external communication. Throughout the incident response process, the Legal team is engaged, as appropriate, and helps consider whether disclosure is required once a determination is made in connection with the company's leadership and the CMT.

We identify, assess and manage material risks from cybersecurity threats through our GIS Program as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We deploy a defense-in-depth strategy, acknowledging the importance of people, processes and technology in upholding information security. The strategy incorporates multiple layers of controls, including, monitoring, vulnerability management, identity and access management and security assessments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our program is aligned with the National Institute of Standards and Technology Cybersecurity Framework (NIST) and other technical standards and frameworks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have a robust cybersecurity defense response plan that provides a documented framework for handling security incidents and facilitates coordination across multiple parts of the company.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We invest in threat intelligence and operate a Cyber Defense Center, which acts as our hub of information sharing and threat intelligence analysis.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We incorporate external expertise and reviews into our cybersecurity risk management program and continue to engage leading professional consulting firms to assist our company in incorporating cybersecurity best practices.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We provide annual cybersecurity awareness and ongoing phishing training, and we routinely conduct cybersecurity attack simulation exercises, which includes participation from various levels of management.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Following a risk-based approach, we conduct due diligence reviews of our third party providers for potential cybersecurity risks to the company. We also maintain a cross-functional Third Party Risk Management program, which partners with our GIS, Information Governance, and Operational Resilience teams, among others, to manage and monitor third party risk presented by CME Group vendors and certain third parties of third parties (fourth parties). The teams conduct initial due diligence on vendors and monitor cyber-related incidents and known vulnerabilities with the goal of enhancing processes, improving risk management and partnering on exit planning and testing for certain vendors associated with essential functions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have insurance against certain cybersecurity and privacy risks and attacks.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are an active participant in the financial services industry and government forums and information sharing programs, designed to improve both internal and sector cybersecurity defense. These valuable external partnerships are established and maintained in order to gain more timely, comprehensive and actionable threat information across geographies and industries and to facilitate the exchange of best practices and security techniques. They allow for a high degree of collaboration and cooperation with local, state, federal, and international law enforcement and intelligence agencies, industry groups, and other private sector chief information security officers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We regularly test the design and effectiveness of our information security controls and processes through a program of testing performed by internal and independent third-party teams. Remediation of gaps and opportunities identified through testing are tracked through to closure. Testing activities support a variety of regulatory requirements and external industry certifications held by CME Group.

The board provides oversight of cybersecurity risks and has designated primary responsibility to the risk committee which oversees our information security programs, including cybersecurity, and is actively involved in monitoring the progress of key cybersecurity initiatives. Our board and risk committee receive regular updates on the activities and effectiveness of our GIS Program, including reports on incident response plan testing exercises and results of compliance testing and third-party evaluation results. Our CISO provides quarterly, or as needed, reports and updates to our board and risk committee on the company's cybersecurity risk management program and meets with the risk committee at least annually in a private session. The CISO has an indirect reporting line to the risk committee. We also engage with leading professional consulting firms to provide periodic updates to the board on cybersecurity-related risks in the evolving threat landscape and to provide education on best practices for board oversight of our GIS Program.

To date, the company is not aware of risks from cybersecurity threats, including as a result of any previous cybersecurity incidents, that have materially affected or are reasonably likely to materially affect the company, including our business strategy, results of operations or financial condition.

See "Item 1A - Risk Factors" beginning on page [16](#i93ed40d324b64de799da10954483467e_31) for additional information on cyber attacks and other cybersecurity risks the company faces.

**2025 Proxy Statement**

We have adopted an insider trading policy governing the purchase, sale and other dispositions of our securities by our directors, officers, and employees, as well as by the company itself. We believe our insider trading policy is reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the company. A copy of our insider trading policy is filed with our most recent Annual Report on Form 10-K as Exhibit 19.1.

4The "Peer Group TSR" set forth in this table utilizes a custom group of peer companies, which we also utilize in the stock performance graph required by Item 201(e) of Regulation S-K included in our Annual Report for the year ended December 31, 2024. The comparison assumes $100 was invested for the period starting December 31, 2019, through the end of the listed year in the company and in the custom group of peer companies used in our performance graph, respectively. The custom peer group consists of: Cboe Global Markets Inc, Deutsche Boerse Ag, Intercontinental Exchange Inc, London Stock Exchange Group Plc and Nasdaq Inc. Historical stock performance is not necessarily indicative of future stock performance.

5We determined cash earnings to be the most important financial performance measure used to link company performance to "Compensation Actually Paid" to our PEO and Non-PEO NEOs in 2024.

**EQUITY GRANT PRACTICES**

The following is a summary of our equity grant practices and the role of the committee in approving awards:

&nbsp;&nbsp;&nbsp;&nbsp;• Our annual equity awards are granted on September 15th, or in the event the 15th is not a business day, the closest business day thereto. We do not time the grant of equity compensation in relation to the disclosure of material nonpublic information.

&nbsp;&nbsp;&nbsp;&nbsp;• At a meeting prior to the annual grant date, the committee approves the awards for the senior management group based upon the target equity opportunities and recommendations from the Chairman and Chief Executive Officer (for executives other than himself) using a pre-set calculation of a percentage of base salary to determine the award value. Actual awards are granted based on the previously approved award value and the closing price on the actual grant date. The committee receives a report of the actual awards at a subsequent meeting.

&nbsp;&nbsp;&nbsp;&nbsp;• The committee has delegated authority to the individual in the role of Chief Executive Officer to approve annual, sign-on, retention and initiative-based equity awards to employees below our senior management group other than our chief accounting officer, within parameters set by the committee. The committee is provided with an annual report on awards granted under such delegated authority.

&nbsp;&nbsp;&nbsp;&nbsp;• Our Omnibus Stock Plan and our Director Stock Plan prohibit the granting of options or stock appreciation rights below the market value on the date of grant, the repricing of existing awards, and payment of dividends on performance-based shares prior to the achievement of performance goals. Dividends relating to outstanding shares of unvested time-based restricted stock are accrued and paid out at vesting.

The equity targets for our named executive officers were established based upon a review of the nature of the responsibility of the position of the executive within CME Group, the competitive market data derived through our benchmarking practices and

------

<u>[**Table of Contents**](#i93ed40d324b64de799da10954483467e_7)</u>

the ability of the employee to impact the overall growth and performance of CME Group based upon his or her role within the company. As discussed in more detail on page 63, we generally target total compensation in the 50th percentile of our peer group. Through competitive compensation analysis, we compare equity compensation on a standalone basis as well as part of an executive's overall total compensation.

The committee has the discretion to adjust the annual equity awards to distinguish for individual performance. The annual equity awards for the named executive officers were made at the target levels for 2024 and were comprised of 50% performance shares and 50% time-vested restricted stock. The performance shares, if earned, vest in full following the three-year performance period and the restricted shares vest ratably over a four-year period unless otherwise provided.

**ITEM 5. OTHER INFORMATION**

On February 18, 2025, Jonathan Marcus, Senior Managing Director and General Counsel adopted a trading plan intended to satisfy the affirmative defense of Rule 10b5-1(c). The plan provides for the potential sale of up to 6,568 shares of the company's Class A common stock. The actual number of shares sold under Mr. Marcus' plan will depend on the number of shares delivered at the time that certain of his equity awards vest during the term of the plan following the fulfillment of tax withholding obligations and subject to other conditions as set forth in the plan.

The plan expires on March 31, 2026 or upon the earlier completion of all authorized transactions under the plan. In determining the number of shares that may be sold under the plan it is assumed that the performance shares vesting during the plan vest at target.

**PURPOSE & STATEMENT OF POLICY** 

CME Group has adopted this policy to comply with all applicable laws and regulations relating to trading activity that apply to CME Group as a publicly traded company and the operator of highly-regulated global businesses.

**APPLICABILITY AND SCOPE**

All employees, internal consultants, members of the CME Group Board and members of committees of a CME Group exchange (collectively referred to as ***"colleagues"***) are required to follow the terms and conditions for trading activity detailed in this policy. All colleagues are expected to exercise their best judgment and comply with the law — avoiding the appearance of any misconduct in their personal trading activities. When we refer to "you," in addition to you, we also mean your ***connected persons*** (as defined in **Appendix A**).

This policy is not meant to address every situation or issue that can arise with respect to trading activity. Trading strategies or issues not specifically addressed in this policy should be evaluated against the objectives in this document and the **CME Group Code of Conduct**, the **Board of Directors Code of Ethics** and the **Rulebooks** of CME, CBOT, NYMEX and COMEX, as applicable.

***If you have questions or are unsure about the application or interpretation of this policy as it relates to your own particular circumstance or personal trading activity, contact* Corporate Compliance *and refer to the* Frequently Asked Questions*.***

------

Suspected violations of this policy should be reported through one of the reporting channels made available in the **Speak Up and Escalation Policy**, including the CME Group Compliance & Ethics Helpline (www.ethicspoint.com) and the compliance officer for your business, if any.

------

**CME GROUP TRADING REQUIREMENTS AND RESTRICTIONS**

As a general rule, trading activity in financial markets should be kept to a reasonable level, oriented toward investment rather than speculation, and should not distract from your responsibilities. Significant trading activity during work hours may rise to the level of a conflict of interest for employees and internal consultants under the **Code of Conduct**. Certain trading activity, although permitted under applicable laws, may be prohibited under the **Conflicts of Interest Policy** based on actual or perceived conflicts of interest due to your role at CME Group or the relationship between CME Group and the company whose stock you may be trading.

Breaches of CME Group's commitments as set forth in this policy can have serious repercussions on many levels, including legal and regulatory consequences and damaging the company's reputation. Potential violations of this policy will be subject to investigation by CME Group, and any failure to comply with this policy may result in discipline, up to and including termination or failure to be nominated for a future term on the Board of Directors, referral to regulatory authorities and potential civil and criminal exposure.

**APPENDIX A: Transactions in the securities of CME Group Inc., the securities of companies with which CME Group does business and in other financial instruments** 

This Appendix applies to all CME Group Board members and employees and internal consultants of CME Group. It also applies to trading activity on the company's behalf.

**YOU MAY NOT ENGAGE IN INSIDER TRADING OR MARKET ABUSE**

Most jurisdictions where CME Group conducts its business legally prohibit insider trading and other forms of market abuse and have sophisticated surveillance activities to identify and prosecute violations of the laws.

If you are aware of or have access to ***inside information*** (sometimes also referred to as ***material, non-public information***) relating to CME Group **or to any other company**, you **<u>may not</u>**:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Buy or sell the financial instrument at issue (e.g., CME Group shares or the shares of another company you have inside information about). ***This prohibition applies to any account in which you have a financial interest, including accounts of your connected persons (defined below). It is your obligation to make your connected persons aware of, and understand and comply with, the provisions and obligations of this Policy.***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Give, communicate or in any way convey inside information to anyone else (referred to as ***"tipping"***).

When trading securities, the term ***inside information*** includes any information positive or negative that if publicly disclosed:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)might have an effect on the market for the securities of the issuer;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)might affect an individual investment decision of a reasonable investor; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)might cause an insider to change his/her trading patterns.

Information that has not been widely disseminated to the public is generally considered to be non-public information. In general, material information is considered public once it has been broadly distributed through a press release or filed with the Securities and Exchange Commission and the market has had time to absorb the information, typically 24 hours.

Even after termination of your employment or service with or to the company, if you continue to possess ***inside information***, this policy continues to apply to your personal trading activities until that information has become public or is no longer material.

------

***Connected persons*** are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the following members of your family:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) your spouse or civil partner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) any other person (whether of a different sex or the same sex) with whom you live as partner in an enduring family relationship;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii) your children, including any adopted children, step-children and the children of a person within paragraph (ii) until they are considered an adult, no longer financially supported by you and no longer sharing the same household; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv) any other relative of yours who has shared the same household as you for at least one year

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any company in whose equity securities (e.g., stock) you and/or any member or members (taken together) of your family are directly or indirectly interested (actually or contingently) so that they are (or would be) able to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) exercise or control the exercise of 20% or more of the votes able to be cast at general meetings on all, or substantially all, matters; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) appoint or remove directors holding a majority of voting rights at board meetings on all, or substantially all, matters

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) a person acting in their capacity as trustee of a trust:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) the beneficiaries of which include you or a person who is connected with you; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii) the terms of which confer a power on the trustees that may be exercised for your benefit or the benefit of any such person, other than a trust for the purposes of an employer sponsored share scheme or a pension scheme; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) any person in respect of which you have a direct or indirect material interest in the outcome of a trade, other than obtaining a fee or commission for execution.

The definition of insider trading in the European Union is broader to include when an individual who holds inside information deals, tries to deal or takes any other form of trading decision (including cancelling an order) on the basis of inside information. Please refer to the Market Abuse chapter of the **CME Group EMEA and APAC Compliance Manual** for further information.

***Any information that could be expected to affect the price of a financial instrument, whether it is positive or negative, or might affect an individual investment decision of a reasonable investor, should be considered inside information.***

**The below list contains examples of information that is likely considered inside information:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Projections of our future earnings or losses or actual changes in our earnings inconsistent with expectations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Information on our average rate per contract or contemplated significant pricing changes that could impact our stock price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● A pending or proposed merger, acquisition or other corporate development, or that discussions or negotiations with respect to such activity are in progress as it relates to both CME Group stock and the stock of the other party.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Significant dividend increases or decreases, including information relating to our Q1 dividend and our annual variable dividend.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● A significant investment in technology that is not accounted for in our published expense guidance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● A new product, service or technology offering that is expected to generate a significant amount of new revenue.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● A major change in senior management, material change in staffing levels or a material personnel restructuring.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Material pending or threatened litigation, regulatory or governmental actions, as well as any significant developments in connection with such matters (such as their termination or resolution).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● The gain or loss of a significant client or vendor.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● The imminent change in a credit rating by a rating agency.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Knowledge of the occurrence, or suspected occurrence, of a potentially significant cyber incident or privacy breach.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● A technology or operational issue resulting in a significant outage in our markets or that could result in significant loss to the company

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Significant distress of one of our Clearing Members or significant clients.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● An investment decision that could have a significant impact on the price of an instrument (e.g., a decision on behalf of CME, including the Clearing House, to make a significant investment or divestiture in a specific fund that could have a material impact on the price of such fund).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Present or anticipated cash positions, commodity interests or trading strategies of a client.

It is your responsibility to comply with this policy against insider trading and market abuse. **This means from time to time, you may not be able to buy or sell CME Group or another company's stock or a particular financial instrument, even if you planned to make the transaction before gaining access to or learning of the inside information, and even though you believe you may suffer an economic loss or forego anticipated profit by waiting.** CME Group believes that such lost opportunities are a necessary consequence of our commitment to compliance with the securities and market abuse laws and to fair and equitable trading markets. Refer to the **Frequently Asked Questions** for more information on what transactions are allowed during a trading restriction period or when you otherwise have access to inside information.

**When in doubt, it is best not to trade:** Determining if information is considered inside information is complicated and the outcome may differ from the initial assessment with the benefit of hindsight and actual performance of the financial instrument. The responsibility for determining whether you are in possession of inside information rests with you, and any action on the part of any other colleague pursuant to this policy (or otherwise) does not in any way constitute legal advice or insulate you from liability under the applicable securities laws. You could be subject to severe legal penalties and disciplinary action by CME Group for any conduct prohibited by this policy or applicable securities laws.

**SPECIFIC REQUIREMENTS RELATING TO CME GROUP STOCK** 

**Speculative and hedging transactions in CME Group stock are prohibited**

Investing in CME Group stock provides an opportunity to share in the long-term growth of CME Group. Short-term investments based on price fluctuations may put your personal gain in conflict with the best interests of CME Group and its shareholders. Consequently, you are prohibited from "short-selling" CME Group stock, from buying or selling puts, calls, options, spread bets, warrants or similar instruments on CME Group stock or engaging in other transactions with respect to CME Group stock that might be considered speculative.

Hedging or monetization transactions such as zero-cost collars and forward sale contracts that allow a person to lock in a portion of the value of their shares, often in exchange for all or part of the potential for upside appreciation in the shares, also are prohibited. Such transactions permit you to retain ownership of CME Group stock while limiting the risks and rewards of such ownership and, therefore, your interests may no longer be aligned with those of CME Group or its shareholders.

**Regular quarterly and event trading restriction periods prohibit certain colleagues from trading CME Group stock**

Some colleagues are subject to additional restrictions on trading CME Group stock for a period of time, referred to as "trading restriction periods," because of their job functions or information regarding our financial results to which they routinely have access or can be presumed to have routine access. During these trading restriction periods, those colleagues are prohibited from directly or indirectly (such as through a connected person) trading in CME Group stock. ***Our regular quarterly trading restriction periods surrounding the release of our financial earnings begin on the 15***<sup>th</sup> ***day of the last month of each calendar quarter (March, June, September, December) and end 24 hours after the earnings are publicly released for that quarter.*** 

We also may impose event-specific trading restriction periods for material events, such as a significant transaction, litigation or investigation. You will receive notice from the Office of the Secretary if you are subject to a regular or event-specific trading restriction period. Other than the regular quarterly trading restriction period, you should not disclose the fact that you are prohibited from trading CME Group stock to anyone. ***Remember that trading restriction periods are not the only time you are precluded from trading CME Group stock — you cannot trade CME Group stock any time you are in possession of or have access to inside information, whether or not you've been specifically told that you are subject to a trading restriction period.*** Refer to the **Frequently Asked Questions** for more information on what transactions are prohibited during a trading restriction period.

------

In limited circumstances, we may impose an event-specific trading restriction period on another company's stock when our colleagues may have access to inside information regarding that company. One example is when another company is involved in M&A activity with CME Group.

***Pre-arranged trading plans***

Under U.S. securities laws, in certain circumstances, an individual may pre-arrange a plan to trade in CME Group securities or the securities of other companies in the future. A pre-arranged trading plan may provide an individual with an affirmative defense to a charge of violating insider trading laws. This means that you may be able to pre-arrange transactions which may go forward, irrespective of your knowledge of inside information at the time of such transactions. Such arrangements must be entered into in good faith, at a time when you do not possess inside information and must meet the criteria set forth in Rule 10b5-1. Establishing any trading plan involving CME Group securities must be pre-cleared by the Corporate Secretary. Refer to the **Frequently Asked Questions** for more information.

***Company repurchase of shares***

The Board of Directors of CME Group may from time to time authorize CME Group to repurchase CME Group securities under such terms and conditions that the Board of Directors may determine. It is CME Group's policy to comply with all applicable securities and state laws and this policy when the company is engaging in transactions in CME Group's securities.

***Confidentiality of CME Group information***

Everyone subject to this Appendix has an ethical and legal obligation to maintain the confidentiality of information about CME Group and the companies with which we do business as described in the **Code of Conduct,** the **Board Code of Ethics**, the **Confidentiality and Data Protection Policy** and in the **Rulebooks** of CME, CBOT, NYMEX and COMEX, as applicable to your role.

------

**APPENDIX B: Requirements relating to individuals subject to Section 16 of the Exchange Act**

This Appendix applies to all ***executive officers*** (the Chairman and Chief Executive Officer, members of the Management Team and the Chief Accounting Officer) and CME Group Board Members.

**TRADING RESTRICTIONS**

You may purchase or sell CME Group securities ***only*** if you can satisfy **<u>ALL</u>** of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● You DO NOT have access to inside information;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● You are NOT subject to a trading restriction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● You have pre-cleared the transaction with a member of the Office of the Secretary; AND

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● You have not engaged in a matchable transaction within the prior six months if the transaction involves CME Group equity (meaning if you want to sell shares in the open market you have not purchased shares in the open market within the last six months and vice versa).

If you have engaged in a matchable transaction within the last six months, the Nominating and Governance Committee may authorize you to engage in the proposed transaction; provided that such transaction would not result in a recognizable gain for purposes of Section 16(b) of the Exchange Act.

**MANDATORY PRE-CLEARANCE PROCEDURES**

All of your transactions involving CME Group securities must be pre-cleared by a member of the Office of the Secretary. These procedures will help ensure you are not engaging in insider trading and you are fulfilling your reporting obligations with respect to such transactions.

CME Group Board Members, the Chairman and Chief Executive Officer and members of the Management Team also are subject to stock ownership guidelines which should be considered prior to engaging in any transaction involving CME Group equity.

Transactions requiring pre-clearance include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Any transactions involving your CME Group securities (including the execution of a pre-arranged trading plan, the execution of a limit order, a gift, or a contribution to or transfer from a trust or any other transfer); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Any transactions by your connected persons involving CME Group securities in which you have a direct or indirect financial interest (for example, the ability to profit in some way from transactions in the securities). *The SEC will presume you have a financial interest in securities held by your immediate family members sharing the same household.*

------

Pre-clearance of a transaction by a member of the Office of the Secretary does not authorize or condone a transaction that may contravene securities law, such as trading with inside information and does not necessarily protect you from liability under the laws prohibiting insider trading. Each pre-clearance expires on the second business day following the date the pre-clearance was issued, unless otherwise extended by a member of the Office of the Secretary. In addition, the pre-clearance may be revoked at any time before the trade by any member of the Office of the Secretary and by the issuance of a "no trade" directive. You will be notified if a "no-trade" directive is issued or pre-clearance is revoked.

To request pre-clearance for a transaction, please contact the Corporate Secretary and provide all of the following information:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Description of proposed transaction, such as whether it is an open market sale or purchase of stock or notes, 10b5-1 pre-arranged trading plan, gift, etc.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Anticipated date of the transaction and whether the transaction remains subject to any conditions such as stock price; AND

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;● Name and contact information of the broker executing the trade.

In her absence you may also contact the General Counsel or the Assistant Corporate Secretary.

In order for the Office of the Secretary to complete your Section 16 forms, your broker must provide detailed transaction information. You must authorize the broker to provide such information directly to the Office of the Secretary.

**NOTIFICATION OF SALES OF CME GROUP STOCK** 

In addition to pre-clearance, CME Group Board Members and members of the Management Team planning to sell shares of CME Group stock also must advise the Chairman and Chief Executive Officer of their intention.

**COMPLIANCE WITH RULE 144**

You must ensure your broker completes all necessary paperwork for any sales made in accordance with Rule 144; provided, however, the company may undertake the filing of the Form 144 with your Section 16 report. Rule 144 applies to all open market sales of shares of CME Group by any "affiliate" of CME Group. In general, CME Group Board Members and executive officers of CME Group can resell shares of CME Group stock owned by them provided they follow the provisions of Rule 144. Unless you comply with the provisions of Rule 144, you may not be able to make open market sales of shares of CME Group without registering the shares under the Securities Act.

**REPORTING OF TRANSACTIONS IN CME GROUP STOCK**

All of your transactions in CME Group Class A and Class B common stock must be reported to the Securities and Exchange Commission in accordance with Section 16(a) of the Exchange Act, typically within two (2) business days following the date of the trade. The company is required to disclose any late filings in its proxy statement.

------

***Reports required to be filed under Section 16(a)***

CME Group Board Members and executive officers are individually responsible for timely reporting to the SEC any purchases, sales or other acquisitions or dispositions of equity securities of CME Group "beneficially owned" by such persons. However, the Office of the Secretary will prepare and file your Section 16 forms for you. ***"Beneficial ownership"*** includes any security in which a person has any direct or indirect financial interest. Equity securities of CME Group include securities which are exercisable or exchangeable for or convertible into, or which have a value which derives from the value of, an equity security of CME Group. These latter securities, known as "derivative securities," include: stock options; warrants; convertible securities; stock appreciation rights and similar rights with exercise or conversion privileges at a price related to an equity security; or similar securities with a value derived from the value of an equity security. For purposes of Section 16, derivative securities are deemed to be the same class of equity security as the underlying security.

**SHORT SWING LIABILITY FOR PURCHASES & SALES WITHIN SIX MONTHS**

To deter insiders from profiting on transactions in the equity securities of CME Group on the basis of undisclosed information, Section 16(b) of the Exchange Act requires you to disgorge your "statutory profit" realized in either a non-exempt purchase and sale or a non-exempt sale and purchase (or any number of these transactions) of equity securities of CME Group (including derivative securities) which takes place within any six-month period. This area of the law is complicated. Additional information on this restriction, including what constitutes an exempt transaction, is included in the **Frequently Asked Questions** which is available on OpenExchange and in the portal for board materials and from the Office of the Secretary.

**PROHIBITION AGAINST SHORT SALES UNDER SECTION 16(C)**

Section 16 insiders are specifically prohibited under Section 16(c) of the Exchange Act from making any short sale of CME Group equity securities. A short sale has occurred if the seller (1) does not own the securities sold or (2) owns the securities sold, but does not deliver them against a sale within 20 days thereafter or does not within 5 days after the sale deposit the securities in the mail or other usual channels of transportation.

**RESTRICTIONS ON PLEDGING CLASS A COMMON STOCK**

CME Group Board Members and executive officers are also prohibited from entering into pledging arrangements relating to their shares of Class A common stock, including pledging shares for margin or collateral.

**CME GROUP CLASS B COMMON STOCK AND TRADING RESTRICTIONS**

Board members may purchase or sell the Class B share associated with a membership on the CME exchange during a trading restriction; provided that such Board member does not have access to

------

inside information at the time of the transaction. Such transaction must still follow the pre-clearance and reporting requirements described in this Appendix.
