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 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 relating to CME Group’s transition to the Google Cloud and minimize duplicative costs during the transition between maintaining the on-premise environment and the Google Cloud environment;

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 members and other counterparties, and to satisfy the margin and liquidity requirements associated with the BrokerTec matched principal business;

our dependence on third-party providers and exposure to risk through third parties, including risks related to the performance, reliability and security of technology used 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 around the world, 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 execute our growth strategy and maintain our growth effectively; our ability to manage the risks, control the costs and achieve the synergies associated with our strategy for acquisitions, investments and alliances, including those associated with the performance of our joint ventures with S&P Dow Jones (S&P Dow Jones Indices LLC) in index services, our primary business and distribution partners’ actions and our partnership with Google Cloud, including our ability to manage the successful implementation of our agreements with Google and our data center partners; variances in earnings on cash accounts and collateral that our clearing house holds for its clients; 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;
