Our integrated clearing function is designed to ensure the safety and the soundness of our 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 a trading 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.

Our Strategic Initiatives

The following is a description of our strategic initiatives:

Maximize Futures and Options Growth Globally — We continue to focus on driving growth and new customer acquisition by expanding, innovating and scaling our core offerings, and increasing participation from customers.

We do this by optimizing our global sales team, cross-selling certain products, expanding the strength of our existing benchmark products, launching new products and services, strengthening our existing product and service offerings, securing intellectual property rights to new products, enhancing our relationships and broadening our base of distribution partners, and deepening open interest in our core futures and options offerings.

We have further focused on building upon cloud-based data distribution capabilities as a more flexible and potentially efficient means of providing data to our clients.

In 2024, CME Group futures and options had a record average daily volume of 26.5 million contracts , with a volume record in our interest rates asset class for the third consecutive year.

It was also a year of volume records for multiple products, including Treasury futures and Ultra 10 Year Treasury Note futures, SOFR futures, Bitcoin futures, Natural Gas (futures and options), Metals futures and options and a record number of contracts executed via Basis Trade at Index Close ("BTIC").

We continue to expand and deepen our customer base worldwide and offer customers around the world the most broad and diversified portfolio of benchmark products.

Some of our new products introduced over the past year include:

• Additional Cryptocurrency Reference Rates and Real-Time Indices

• Options on Euro short-term Rate Futures (€STR)

We continue to expand and deepen our customer base worldwide and offer customers around the world with the most broad and diversified portfolio of benchmark products.

We believe we have a significant opportunity to expand the participation of our non-U.S.

customer base in our markets.

Our penetration of these markets lags our development in the U.S., and we believe that there is room for significant growth and development of these financial market s.

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.

• We list products at the micro size across all six major derivatives asset classes.

These products are designed to attract a new customer base.

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

• 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.

• 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 .

• 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.

• 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.

• 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:

• 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.

• 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.

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.

We have increased our customer base and continue to target cross-asset opportunities across client segments and across cash and futures platforms, driving sale and generating new client participation across all regions.

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.

• 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.

CME Group continues to introduce tools which assist our clients in managing their risks.

The FX and Metals Market Profile Tools on Quant Analytics offer simple and effective methods for clients to compare and contrast our leading FX and metals products and liquidity pools side-by-side, which in turn enables clients to analyze their opportunity to minimize costs and achieve best execution by accessing highly complementary liquidity pools across cash and futures markets.

We expect to continue to expand our analytics suite in the future as well.

In 2024, we launched €STRWatch to help clients manage risk around European Central Bank (ECB) policy decisions.

This tool builds on the success of CME Group’s FedWatch, SOFRWatch and TreasuryWatch tools.

CME Group Volatility Indexes (CVOL) comprises a total of 42 indexes, including 7 unique broad-based benchmarks such as the Treasury Volatility Index and Commodity Volatility Index.

In 2025, we are planning to launch CME FX Spot+ as another tool for our customers to increase access, transparency and trading opportunities across spot FX and FX futures markets.

CME FX Spot+ is an all-to-all spot FX marketplace that will connect liquidity between two trading environments, whereby spot FX participants will have expanded access to CME FX futures liquidity in OTC spot terms within an open, transparent, central limit order book environment, while FX futures market users will have expanded access to OTC FX liquidity.

We continue to enhance our retail strategy focusing on the growth of top-tier and large new-to-futures brokers, which resulted in a record number of new retail accounts.

Retail remains a core tenet of our new client acquisition strategy, and we are focused on bringing new-to-futures brokers to our markets.

Diversify our Business and Revenue - Our acquisition of NEX strengthened our role in global financial markets infrastructure and information services, adding complementary cash, spot, and OTC businesses, and scale to our listed interest rate and FX products, while broadening our global client base.

It also further diversified our customer base and relationships outside the U.S.

It gave us access to repo customers, and positioned us to grow our repo activity in the U.S.

It allows us to offer relative value trading solutions for the cash treasury marketplace, and to bring the expanded capabilities of our Globex platform to BrokerTec customers.

The transaction expanded CME Group’s position in the large, highly-competitive and highly-fragmented global FX marketplace, offering both order book trading and relationship-based trading solutions for customers.

The acquisition added strength in underlying customer marketplaces, especially around regional bank customers and other market participants outside of North America, and expanded our market data solutions beyond futures and options into cash and OTC offerings.

CME Group is well-positioned to capitalize on its ability to license CME Term SOFR, administered by our subsidiary, CME Group Benchmark Administration Limited.

CME Term SOFR is the only SOFR rate endorsed by the Alternative Reference Rates Committee (ARRC) and the Federal Reserve Board has formally endorsed the forward-looking term rates based on SOFR .

In 2010, CME Group acquired a majority stake in Dow Jones Indexes, which was combined with S&P’s index business in 2012 to form S&P Dow Jones Indices LLC, of which CME Group now has a 27% ownership stake.

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.

As part of the joint venture, we acquired 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.

We also act as the joint venture's licensing agent and distribution services provider.

Our acquisition of the IHS Markit indices business (S&P Dow Jones Indices), includes leading fixed income and credit indices, such as iBoxx, iTraxx and CDX.

In 2024, our subsidiary, CME Securities Clearing Inc.

(CMESC) filed an application with the SEC to become a Securities Clearing Agency, which would be regulated by the SEC.

The goal is for CMESC to help market participants comply with upcoming U.S.

Treasury clearing requirements and, ultimately, to position the company to offer additional capital and operational efficiencies to its clients.

We are preparing to launch this service following approval from the SEC.

• 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.

• Introducing new services and tools to assist our clients in managing 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.

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 implementation of regulatory reform in the U.S.

With the ongoing

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 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.

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 OTC interest rate swaps, FX forwards and commodity swaps.

In 2023, we launched CME SPAN 2 for certain futures and options on energy products, an enhancement of our Standard Portfolio Analysis of Risk (SPAN) margin framework, which provides enhanced risk management capabilities in a single, unified interface across futures and options, cleared OTC products and portfolio margining programs.

In 2024, we expanded SPAN 2 to equity products.

As CME SPAN 2 is implemented, margins for diversified portfolios will consist of products using the enhanced CME SPAN 2 framework, in addition to the existing SPAN framework, ensuring appropriate levels of offsets will continue to be provided across products subject to the SPAN and SPAN 2 frameworks.

CME Group provides various tools and services to assist customers with capital and operational efficiencies, including:

• CME Clearing provides 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.

• Portfolio margining allows firms to capitalize on margin offsets between futures, options and cleared OTC instruments with common risk factors.

Cross-margining allows firms to achieve portfolio margin efficiencies for offsetting positions between two clearing houses, including CME and Fixed Income Clearing Corporation (FICC) or CME and Options Clearing Corporation (OCC), through reduced performance bond requirements.

Through an enhancement to our arrangement with FICC, in January 2024, we partnered with The Depository Trust & Clearing Corporation (DTCC) and began offering enhanced capital efficiencies to our eligible clearing firms when trading U.S.

Treasury securities and CME Interest Rate Futures.

With the new arrangement implemented, 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.

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 ap proximately $72 bill ion.

• Applied Offsets:

Applying offsets across correlated futures and options on futures contracts across all asset classes traded at CME Group.

• Portfolio Margining:

Offering margin offsets between futures and options on futures and cleared OTC instruments with common risk factors.

• 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 notes and bonds and certain repo transactions.

We continue to increase participation with a stable pipeline of additional interested clearing firms, as well as new market participants seeking access to the program.

Partnership with Google Cloud - In November 2021, we announced a 10-year strategic partnership with Google Cloud to accelerate CME Group’s move to the cloud, which we expect will transform derivatives markets by expanding access and creating efficiencies for market participants.

The partnership will focus on expanding access to CME Group’s infrastructure, advancing real-time data and analytics capabilities, co-innovating new products and services, increasing efficiencies and driving resiliency in the financial markets’ ecosystem.

In 2022, we built our cloud instance on the CME Group Google Cloud platform.

In 2023, we began executing against the plans to move our non-latency sensitive applications, including clearing and market data, to the CME Group Google Cloud Platform.

The migration of these applications will enable a more efficient way for us to commercialize and launch new clearing and data products.

In 2024, we began migrating our clearing applications to the Cloud and the majority of the daily clearing cycle processes for futures and options on futures are operating on the Cloud as of the end of 2024.

The full migration of clearing processes is expected to be completed in 2025.

In 2024, we also announced that Google Cloud will build a private Google Cloud region and co-location facility in Aurora, IL, which will allow our customers to choose their mode(s) of accessing our markets.

We continue to make progress in preparing to move the markets.

The partnership with Google Cloud allows us to modernize and simplify our architecture, enabling quicker delivery of value for internal and external customers while reducing operational risk and gaining operational efficiencies and maximizing the value of various analytics, including clearing analytics, which we expect we will be able to offer more bro adly.

CME Group and Google Cloud have partnered and begun building a new private Google Cloud region, and a co-location facility, in Aurora, Illinois, which will host Google Cloud's platform designed to support global trading of CME Group's futures and options markets, and offer derivatives traders cloud-based, ultra-low-latency networking, and high-performance computing.

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.

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.

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 educating our regulators and policymakers on potential impacts to the marketplace.

We are also focused on impacts from the new administration and its federal regulatory appointees and any anticipated changes that may result.

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:

• The implementation of a transaction tax or user fee in the U.S., U.K.

or E.U., 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 and 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 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.

• 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.

• Certain provisions in relation to the E.U.

Regulations on Benchmarks have yet to come into effect, as the E.U.

has extended transitional periods until the end of 2025, and has proposed further legislative changes to apply from 2026 onwards.

It remains possible that data, pricing and analytics provided by CME Group for use by E.U.

supervised entities and use of those benchmarks may be impacted in the future.

• Concerns that European legislators will prohibit or restrict exclusive licenses for benchmark indices, which might impact the profitability of several of our most popular contracts.

For example, the provision of any EUR rates benchmark (e.g.

Term €STR) will need to comply with the E.U.'s Benchmark Regulation, which allows marketing access for such benchmarks only where they meet certain requirements (e.g.

they are provided from an 'equivalent' jurisdiction or they have been endorsed by an E.U.

benchmark administrator).

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

• 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.

• The implementation of rules resulting in negative treatment of the liquidity profile of U.S.

1 unchanged sentence

Treasury securities as collateral could result in increased costs to us and our clearing firms.

• The outcome of the debate regarding the regulation of cryptocurrencies, which may impact our existing offerings or o ur ability to provide future offerings.

• New regulations governing treasury market structure, including potential clearing obligations or promotions of all-to-all cash models.

In December 2023, the SEC adopted a rule that becomes effective in December 2026 for certain U.S.

Treasury cash transactions and June 2027 for repo transactions mandating central clearing of U.S.

Treasury securities and repurchase agreements.

This will require infrastructure changes to facilitate access to clearing for all participants, including indirect participants, to ensure continued liquidity in these critical markets (i.e., ensure access to FICC's clearing and settlement services for indirect participants).

The goal of CMESC is to help market participants comply with these clearing requirements.

• 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).

• 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 systematically important banks (GSIBs), 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.

• The Digital Operational Resilience Act, or DORA, is an EU regulation that requires EU financial services firms to meet requirements in respect of risk management for their use of information and communication technology (ICT) whether internal, or provided by a third party vendor.

DORA establishes technical standards that EU financial entities must implement by January 2025 and imposes requirements relating to risk management, reporting, and ICT service provider oversight.

As our subsidiary, CME Amsterdam BV, is an EU financial entity, it is directly subject to DORA requirements.

In addition, some of CME Group's customers, being EU financial services firms, are also subject to DORA.

In January 2025, the European Commission provided guidance clarifying that financial services provided by a financially regulated entity (including those regulated outside the EU), such as CME, CBOT, NYMEX and COMEX, are not ICT services under DORA.

However, EU financial services firms may be required to impose certain risk management obligations on these entities relating to ICT services that are not considered financial services under DORA.

• 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.
