Forward-Looking Statements

From time to time, in this Quarterly Report on Form 10-Q as well as in other written reports and verbal statements, we discuss our expectations regarding future performance. These forward-looking statements are identified by their use of terms and phrases such as “believe,” “anticipate,” “could,” “estimate,” “intend,” “may,” “plan,” “expect” and similar expressions, including references to assumptions. These forward-looking statements are based on currently available competitive, financial and economic data, current expectations, estimates, forecasts and projections about the industries in which we operate and management's beliefs and assumptions. These statements are not guarantees of future performance and involve risks, uncertainties and assumptions that are difficult to predict. Therefore, actual outcomes and results may differ materially from what is expressed or implied in any forward-looking statements. We want to caution you not to place undue reliance on any forward-looking statements. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events or otherwise. Among the factors that might affect our performance are:

• increasing competition by foreign and domestic entities, including increased competition from new entrants into our markets and consolidation of existing entities; our ability to keep pace with rapid technological developments, including our ability to complete the development, implementation and maintenance of the enhanced functionality required by our customers while maintaining reliability and ensuring that such technology is not vulnerable to security risks;

• our ability to continue introducing innovative and competitive new products and services on a timely, cost-effective basis, including through our electronic trading capabilities, and derive revenues that are commensurate with our efforts and expectations, and our ability to maintain the competitiveness of our existing products and services;

• our ability to adjust our fixed costs and expenses if our revenues decline;

• our ability to manage variable costs associated with CME Group's transition to the Google Cloud, and minimizing the duplicative costs of maintaining both on-premise and Google Cloud environments during the transition;

• the resilience of our electronic platforms and the soundness of our business continuity and disaster recovery plans, including in the event of cyberattacks and cyberterrorism or as impacted by a failure of or disruption at one of our suppliers;

• our ability to maintain existing customers at substantially similar trading levels, develop strategic relationships and attract new customers;

• our ability to expand and globally offer our products and services;

• changes in regulations, including the impact of any changes in laws or government policies with respect to our products or services or our industry, such as any changes to regulations and policies that require increased financial and operational resources from us or our customers, as well as the impact of tariffs and tax policy changes, restrictions on our ability to offer CME Group products and services in specific geographies or to specific customers or limitations or changes in underlying/physical product flows across geographies;

• the costs associated with protecting our intellectual property rights and our ability to operate our business without violating the intellectual property rights of others;

• decreases in revenue from our market data as a result of decreased demand or changes to regulations in various jurisdictions;

• changes in our rate per contract due to shifts in the mix of the 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;

• the ability of our credit and liquidity risk management practices to adequately protect us from the credit risks of clearing firms and other counterparties, and to satisfy the margin and liquidity requirements associated with the BrokerTec matched principal business;

• the ability of our compliance and risk management programs to effectively monitor and manage our risks, including our ability to prevent errors and misconduct and protect our infrastructure against security breaches and misappropriation of our intellectual property assets;

• our dependence on third-party providers and exposure to risk from third parties, including risks related to the performance, reliability and security of technology used by, or facilities provided by, our third-party providers and third-party providers that our clients and third-parties rely on;

• our reliance on third-party distribution partners, including independent software vendors (ISVs), futures commission merchants (FCMs), introducing brokers, broker-dealers, regulatory reporting and data distributors and platform operators, and other partners, for facilitating trading and for market data information, and potential impacts from changes in their business models and priorities;

• volatility in commodity, equity and fixed income prices, and price volatility of financial benchmarks and instruments such as interest rates, equity indices, fixed income instruments and foreign exchange rates; economic, social, political and market conditions, including the volatility of the capital and credit markets and the impact of economic conditions on the trading activity of our current and potential customers;

• our ability to accommodate increases in contract volume and market data and order transaction traffic across the entire trade cycle and the ability to implement enhancements meeting our regulatory obligations and customer needs without failure or degradation of the performance of our trading and clearing systems;

• our ability to execute our growth strategy and maintain our growth effectively;

• our ability to manage the risks, control the costs and achieve the synergies associated with and benefits from our strategy for acquisitions, investments, alliances, strategic partnerships and joint ventures;

• variances in earnings on cash accounts and collateral that our clearing house holds;

• impact of CME Group pricing/fee level and structure and incentive changes;

• impact of aggregation services and internalization on trade flow and volumes;

• any negative financial impacts from changes to the terms of intellectual property and index rights;

• our ability to continue to generate funds and/or manage our indebtedness to allow us to continue to invest in our business;

• industry, channel partner and customer consolidation and/or concentration;

• decreases in trading and clearing activity;

• the imposition of a transaction tax or user fee on futures and options transactions and/or repeal of the 60/40 tax treatment of such transactions;

• increases in effective tax rates, borrowing costs or changes in tax policy;

• our ability to maintain our brand and reputation; and

• the unfavorable resolution of material legal proceedings.
