Listening to our employees
In 2023, we administered a pulse employee experience survey. This shortened survey was
designed to check in on key engagement measures from the comprehensive survey conducted
in 2022. With a 73% participation rate, our 2023 pulse engagement survey showed an overall
engagement score of 70% and indicated employees feel positively about a number of factors– notably that 87% feel they have access to the resources needed to do their jobs effectively
and 76% feel valued.
Detailed division and department breakdowns of the survey results are shared with theappropriate leaders to explore and identify key areas to address with assistance from Human
Resources. We also share the findings with our workforce and proactively develop solutions forareas that received lower levels of engagement or satisfaction.

CME Group has long pioneered groundbreaking solutions for the derivatives marketplace. The CME Group Innovation Lab engages colleagues
across all levels, departments and functions of our organization, and fosters collaborative and inventive thinking to create additional value forour clients and our business. Since 2014, the CME Group Innovation Lab has helped our company to keep a pulse on market needs and innovate
new solutions to respond accordingly.
With our continued focus on innovation, we have made progress through our partnership with Google Cloud in leveraging cloud and cloudbased analytics in ways that benefit our clients.
Some examples of key activities in 2023 include:

Historical Market Data Access: We enabled clients to access our market data from 2014 to the present day via Google
Analytics Hub. This allows them to efficiently query and share data between teams in a reliable and cost-efficient manner.

Referential Data Warehouse: We moved our referential data warehouse application to Google Cloud, which enables ourclients to obtain historical product specification information through Google BigQuery. Clients can now run in-depth historicalanalyses without the cost and burden of storing historical reference data, freeing their resources to focus on growing theirbusinesses.

Margin Services: On the clearing side, we deployed our Risk Calculator in Google Cloud. The Risk Calculator helps clients
calculate and model margin requirements for their portfolios – and moving this to the cloud allows them to run several
scenarios at the same time and with a faster output. The calculator was extended to allow historical and intraday risk runs
by using the scale of the cloud.

Since 2011, we have hosted the annual CME Group Tour Championship to celebrate the culmination of the LPGA season. As in years past, the 2023
event supported St. Jude Children’s Research Hospital – advancing its mission to ensure no family ever receives a bill for treatment, housing or
travel when caring for a sick child. From the season-long Score 1 for St. Jude program – where CME Group contributed $20,000 for each hole-in-one
scored – to our annual benefit concert, we donated a total of $1.3 million to St. Jude in 2023.
The 2023 event marked a historic milestone as CME Group extended its sponsorship agreement with the LPGA through 2025. Beginning in 2024, theTour Championship will offer an enhanced total purse of $11 million. In addition, the winner will take home a record $4 million first-place prize – the largest
single prize in women's sports. Moreover, every competitor who qualifies will be awarded at least $55,000, which is a first for a women's tournament.
We are proud to continue our steadfast support for women in business and sports, at the same time we honor St. Jude for their invaluable
contributions to saving lives and ensuring brighter futures.

As a company that provides risk management tools andservices to our global clients, we approach our own risk
management practices, protocols and programs withthe same level of rigor. Our approach to managing risks
focuses on preserving and protecting our enterprise value
and maintaining and enhancing our reputation. Our Board
has ultimate oversight responsibility for the company’s risk
management activities, including our ERM, Operational
Resilience and Global Information Security (GIS) programs.
Senior management is responsible for managing dayto-day risk and regularly engaging with our Board. The
Board holds management accountable for maintaining aneffective risk management program and operating it within
the acceptable risk appetites that have been recommended
by the Risk Committee and approved by the Board.

Each of the Board’s eight committees has dedicated riskrelated responsibilities,6 with the Risk Committee tasked
with reviewing, assessing and providing oversight of our risk
management practices, including approving the ERM
framework and risk universe. Board committees meet withleaders of key control functions, providing direct access to
Board members and ensuring the independent operationsof such functions. Committee chairs then provide regular
reports to the full Board regarding matters reviewed by theirrespective committees at the Board’s regular businessmeetings.

Furthermore, our ERM Program is designed to ensure
appropriate visibility and reporting of the full range of our
key enterprise risks aggregated on a quarterly basis. Our
Managing Director, Chief Enterprise Risk Management
and Compliance Officer is responsible for our ERM andCompliance programs and reports internally to ourGeneral Counsel and externally to the Risk Committee. We
organize our enterprise risks into six categories: clearing
house, compliance, financial, operational, reputational andstrategic and commercial. The profile of this risk universe
and our associated responses are reported to the Board andsenior management quarterly.

In 2023, we surveyed employees to better understand how they view our Compliance and Ethics Program. The results indicatedthat the program is operating effectively, and employees understand the behaviors expected of them to uphold the integrity of ouroperations. Following the survey, we took the opportunity to communicate the results to our employees and to provide them withenhanced transparency with respect to the program’s allegation intake and investigation and disciplinary processes in support ofour speak up culture.

Upholding a culture of integrity
Integral to our Compliance and Ethics Program is our global
Code of Conduct, which outlines our expectations for our
employees, internal consultants and temporary personnel
resources to act with honesty, thoughtfulness and integrity toprotect CME Group’s reputation. These CME Group colleagues
must certify the Code of Conduct and its related policies
annually. We also developed a guide to Conducting Businessfor Third Parties of CME Group to help our third parties
understand our standards for business conduct. The guidecovers compliance topics similar to those covered in our Codeof Conduct.
Additionally, providing resources and the ability to raise any
instances of misconduct or violation of law is another key
element of our Compliance and Ethics Program. Our Speak
Up and Escalation Policy details the responsibilities of all
CME Group colleagues to report and escalate issues ofconcerning behavior or misconduct. There are multiple
channels through which to raise concerns, including the
CME Group Helpline, where anonymous reports may bemade where locally permitted.

Regardless of whether the report is raised anonymously or not,we make every effort to protect the confidentiality of anyone
who raises a concern in good faith. All reported matters aretaken seriously and investigated as necessary. To demonstrate
appropriate oversight and accountability, aggregatedinformation regarding allegations received and the natureof any remedial action taken by the company are reported
to senior management and at the Board level. Substantiatedviolations result in corrective action or discipline, as
appropriate, up to and including termination.
We marked the 10th year of our Compliance Champions
initiative in 2023, recognizing 67 employees who best
demonstrate CME Group’s business principle of leading withconviction and integrity and embodying the philosophy of ourSpeak Up and Escalation Policy.

Despite a lot ofchange this year, thisgroup continued to go

Corporate
StewardshipAs a derivatives marketplace (not an equity marketplace), CME Group’s markets do not include equities of listed companies and, therefore, CME Group does not (and is not required to)halt its markets based on the public release of information. CME Group has several measures in place on its CME Globex electronic trading platform (CME Globex) that are designed
to operate its markets in an efficient and orderly manner during volatile market conditions, including the following:• Daily Price Limits: Price limits represent the maximum price range permitted for a futures contract in each trading session. If a price limit is hit, the market remains open; however, itcannot trade above/below that price range.
• Circuit Breakers: A series of price limits that, when reached, pause a market for a particular period of time to allow markets to reset.
• Velocity Logic: CME Globex monitors for potentially significant price movements in extremely small time increments. Velocity logic works in conjunction with price banding to address
market prices that move too far, too fast. If a velocity logic violation occurs, the applicable futures market is automatically temporarily suspended, as are all associated options markets.
• Market-Wide Circuit Breakers: A control in CME Group equity products that suspends trading upon the activation of a market-wide regulatory halt pursuant to New York Stock
Exchange Rule 7.12 or Nasdaq Stock Market Rule 4121.
During 2023, 285 circuit breakers were triggered and approximately 820 velocity logic events occurred. The duration of the pause or suspension is based on the applicable contract
and activity in the market. During 2023, there were no market-wide circuit breakers.

The primary venue for trading CME Group futures and options is CME Globex, a resilient open access platform that provides global connectivity to CME Group markets.
CME Group employs many policies, procedures and controls that assist in the mitigation of risks associated with any type of electronic trading on CME Globex, including robust
protocols for risk management, operational and technological resiliency, market surveillance and cybersecurity. A highly granular and precise audit trail of all CME Globex activity
allows us to identify and monitor the trading activity of participants on CME Globex both on a real-time and post-trade basis.
The audit trail also allows us to identify activity originating from automated trading systems. Automated trading systems are used by nearly every type of participant, from farmers to market
makers. Automated systems allow these participants to provide deep liquidity with narrow bid-ask spreads, reduce price and execution risk, minimize market impact and reduce costs.
We believe that open interest—the total number of open futures and options contracts held by market participants at the end of each day—is a reliable measure of the sustainabilityof our markets. Open interest is a measure of market liquidity and the ability of a participant to efficiently initiate or offset a futures or options position. These metrics are available in
the Daily Bulletin—Exchange Overall Volume and Open Interest on our Investor Relations page under Financial and Other Reports—Volume Reports.
The notional volume traded and market depth data published daily for our cash markets businesses are also reliable measures of the sustainability of our cash Treasury and FX
markets. These metrics are available in the UST Market Profile and FX Market Profile tools on the CME Group website.

Discussion ofprocesses for
identifying andassessing conflictsof interest

CME Group has adopted a Code of Conduct that applies to its employees, internal consultants and temporary personnel resources. The Code of Conduct builds on CME Group’sbusiness principle of “leading with conviction and integrity” by setting the tone for a culture of compliance, ethical conduct and accountability, and providing greater detail about the
behavior expected from our colleagues.
The Code of Conduct is supplemented by a more detailed, separate Conflicts of Interest Policy, which sets forth the process for identifying, monitoring and managing actual andpotential conflicts of interest. CME Group seeks to ensure that a conflict of interest does not adversely affect the interests of its organization, its clients, its shareholders or otherstakeholders. CME Group employees, internal consultants and temporary personnel resources are required to disclose potential conflicts of interest, including but not limited to, thoserelating to personal relationships, outside business activities, financial interests and opportunities. These disclosures are reviewed and approved by the Compliance Department andmanagement, as appropriate. In addition, CME Group colleagues must certify to the Code of Conduct and the Conflicts of Interest Policy on an annual basis. CME Group Board
members are subject to the Board of Directors Code of Ethics, which requires that Board members avoid any circumstance that creates or appears to create a conflict between a
Board member’s own interests and the interests of the company. The Nominating and Governance Committee is responsible for compliance with the Board of Directors Code of Ethics.
Board members must certify to this Code of Ethics on an annual basis.
When identifying a situation where an actual or potential conflict of interest cannot be avoided, Compliance recommends appropriate actions to manage, document and, asapplicable, report the situation.

The program includes ongoing cyclical management of vulnerabilities, including coordination of identification, classification, remediation, mitigation and metrics. Internal systems andthird party contracted organizations are engaged in order to execute internal and external penetration tests and vulnerability assessments. The program also includes solutions andprocesses that strengthen our security posture related to the provisioning, deprovisioning and access to our systems based on the principles that information should be limited to thosewith a need for access subject to strong authentication.
As part of the Global Information Security Program, CME Group operates a state-of-the-art Cyber Defense Center that links virtually to its dedicated 24/7 international operational
cybersecurity teams and serves as a global hub for 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, quickly
investigate and respond to cybersecurity events. CME Group’s Global Information Security team conducts analysis and aims to prevent, detect and respond to systemic events thatmight threaten our company, industry or the economy.
The Information Security Program is led by CME Group’s Chief Information Security Officer (CISO) who reports to our Chief Information Officer, a member of our Management Team.
The program is overseen by the Risk Committee of the CME Group Board of Directors and the CISO has an indirect reporting line to the committee.
MARKET REGULATION DEPARTMENT
The CME Group Market Regulation Department is responsible for monitoring our markets to identify and prevent potential rule violations, including disruptive trading practices. The
department utilizes sophisticated regulatory systems to conduct market and trade practice surveillance. A key element of our Regulation Program is educating our market participants
about the requirements and expectations detailed in our rulebooks and trading advisories. When violations are identified and disciplinary action may be warranted, enforcement
proceedings are conducted before a disciplinary panel, and appropriate disciplinary actions are taken.
OPERATIONAL RESILIENCE PROGRAM
The CME Group Operational Resilience (OpRes) Program serves to mitigate potential impacts to our markets, clients, assets and employees and to safeguard the effective availabilityof critical products and services. The OpRes Program is designed to ensure that CME Group can respond appropriately to incidents while protecting the interests of its stakeholders,
ensuring the safety of employees and protecting its reputation and brand.
Our OpRes team continually identifies new and changing business risks to our operations across all CME Group locations through internal monitoring and planning, industry andagency partnerships and various information sharing organizations across the globe. The OpRes team works with departments and employees across the company to assess risks atvarying levels of severity. We have developed a framework for mitigating these risks designed to ensure our business and our markets continue to operate effectively through various
resiliency strategies.
Key aspects of the OpRes Program include:• System Resilience (Disaster Recovery): helps ensure CME Group can recover its systems following an event that impacts the delivery of technology services through production
environments or deployments. This is done by establishing requirements, approving system design and testing that systems can meet their requirements – including their ability torecover with their applicable recovery time objectives as identified within the Business Resilience BIAs and/or by applicable regulatory mandate. As part of the System Resilience
Program, CME Group holds various and ongoing system resilience exercises, which include full failover exercises, response and recovery documentation and the maintenance ofvarious resiliency strategies. OpRes’ testing strategy includes failing over all applications that reside in CME Group data centers and cloud providers.
• The Business Resilience Program: designed to help ensure CME Group can rapidly adapt and respond to internal or external changes – demands, disruptions or threats – while
prioritizing essential business operations and safeguarding people and assets.
• Crisis Analysis and Response: monitors and prepares for unique, high-risk events and potential market threats and ensures the appropriate expertise is gathered from across theenterprise to evaluate, plan for and manage any incidents that may impact markets, customers and brand.
Efforts have been taken to align the OpRes Program with industry-best practices classified in NIST and other applicable U.S. and international standards stemming from ourcategorization as a systemically important market utility and systemically important derivatives clearing organization.

CME Group Inc. makes every effort to use reliable, comprehensive information, but we make no guarantee that it is accurate or complete. We haveno obligation to tell you when opinions or information in this report change. This report is intended to highlight some of the work of CME Group in theareas of environmental, social and governance; it is not comprehensive or necessarily representative of all our activities in those areas.
Details on our financial performance can be found on our corporate website and in our public filings available through the U.S. Securities andExchange Commission (SEC). Our ESG reporting describes those topics which we consider to be the most important to stakeholders when evaluating
environmental, social and governance issues at CME Group. Therefore, materiality and its relevant definition as used in this report and our ESG
materiality review process is different than the definition used in the context of filings with the SEC and under the long-standing U.S. Supreme Court
definition of that term. Issues deemed material or relevant for purposes of this ESG report and for purposes of determining our ESG strategies may not
be considered material for SEC reporting purposes.
This report contains “forward-looking statements” within the meaning of the safe harbor provisions of the U.S. Private Securities Litigation ReformAct of 1995. Forward-looking statements are not historical facts, but instead represent only the company’s beliefs regarding future events, manyof which, by their nature, are inherently uncertain and outside of the company’s control. It is possible that the company’s actual results may differ,possibly materially, from the anticipated goals and targets indicated in these forward-looking statements. For information about some of the risks andimportant factors that could affect the company’s future results, see “Risk Factors” in Part I, Item 1A of the company’s Annual Report on Form 10-K forthe year ended December 31, 2023 and “Risk Factors” in Part II, Item 1A of the company’s subsequent Quarterly Reports on Form 10-Q. CME Group
does not undertake to update any forward-looking statements.
Unless otherwise noted, this report covers initiatives and performance metrics associated with our global operations from January 1 throughDecember 31, 2023. Our past reports are available on our website.
All figures regarding contract volume are for CME Group’s listed futures and options on futures contracts unless otherwise noted. Total contract
volume includes contracts that are traded on our exchange(s) and cleared through our clearing house and certain cleared-only contracts. Volume ismeasured in round turns, which is considered a completed transaction that involves a purchase and an offsetting sale of a contract.
Third parties, including charities, mentioned within this report are not affiliated with CME Group, unless otherwise disclosed. The CME Group Foundationis separate from the CME Group Inc. organization. Any mention of the third parties should in no way be considered to be a solicitation or endorsement
by CME Group on behalf of the third parties named.
Improving the quality, timeliness and availability of data is a key component to properly measure emissions and monitor progress over time. There are
well-known challenges with the quality and reliability of emissions data in many sectors. This means we sometimes rely on estimated versus directly
measured emissions data. Over the years we have made a number of improvements to our reporting. The metrics provided in this report reflect ourcommitment to transparency and progress but are not suitable for immutable year-over-year comparisons at this time.

Calculations and reporting have been done in accordance with the GHG Protocol and also with U.K. SECR mandated reporting with theassistance of an external firm with expertise in this area. Scope 1 GHG emissions are direct emissions from sources that are owned or controlled
by the company. Scope 2 GHG emissions are indirect emissions from sources that are not owned or controlled by the company. Scope 1 andScope 2 operational emissions were calculated using real whole building and prorated data within each building location. For locations where
this information could not be obtained, a value per square foot of office space was used. As a result of exiting from certain premises in 2023 andchanges to the way some landlords report data, we have updated our emissions methodology for 2023. Consequently, CME Group’s Scope 2 and 3
market-based emissions have reduced by some margin. Scope 3 GHG emissions are the result of activities from assets not owned or controlled by
CME Group, but that CME Group indirectly impacts in its value chain. Assumptions for Scope 3 emissions are inherently more common than thosefor Scope 1 and Scope 2 emissions. Where actual activity-based data was available, it was used for Scope 3 emissions calculations. The majority of
Scope 3 emissions were calculated using the GHG Protocol’s spend-based method.
In order to better align with our operational reporting boundary, to conform with evolving industry best practices and based on better informationfrom landlords and data center providers, we made a number of improvements to our reporting, including some notable landlords or data center
providers consider certain portions of emissions (particularly with respect to cooling) as their Scopes 1 or 2 emissions. In those cases, we report thoseemissions in our Scope 3 Upstream Lease Assets category so as to avoid double counting of emissions.
Due to the limited amount of operational control, emissions related to third party subtenants who sublease from CME Group are either excluded
from our emissions or considered to be within our Scope 3 Downstream Leased Asset emissions depending on the circumstances and industry bestpractices.
Emissions related to colocation customers in our largest data center located in Aurora, Illinois is particularly complicated. Because CME Group
has limited operational control or influence over procurement of data center equipment in these spaces nor control over how the equipment is
operated, emissions related to powering this equipment is reported as Scope 3 downstream emissions for CME Group. Our environmental disclosure
initiatives will continue to evolve and new strategies will be developed and implemented and discussed in our future ESG reports.
