Rush Street Interactive, Inc.

This Annual Report on Form 10-K (this “Annual Report”) contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995 that reflect future plans, estimates, beliefs and expected performance. The forward-looking statements depend upon events, risks and uncertainties that may be outside of our control. The words “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “intend,” “may,” “might,” “plan,” “possible,” “potential,” “predict,” “project,” “propose,” “should,” “would” and similar expressions may identify forward-looking statements, but the absence of these words does not mean that a statement is not forward-looking. You are cautioned that our business and operations are subject to a variety of risks and uncertainties, many of which are beyond our control, and, consequently, our actual results may differ materially from those projected.

Any statements contained herein that are not statements of historical fact may be forward-looking statements. Factors that could cause or contribute to such differences include, but are not limited to, those identified below and those discussed in the section entitled “Risk Factors” included elsewhere in this Annual Report:

•competition in the online casino, online sports betting and retail sports betting (i.e., such as within a bricks-and-mortar casino) industries is intense, and as a result, we may fail to attract and retain customers or compete effectively, which may negatively impact our operations and growth prospects;

•failure to comply with regulatory requirements or to successfully obtain a license or permit applied for could adversely impact our ability to comply with licensing and regulatory requirements or to obtain or maintain licenses in other jurisdictions, or could cause financial institutions, online platforms and vendors to stop providing services to us;

•our business depends on strong branding, and if we are not able to maintain, develop, and enhance our brands, our business and operating results may be negatively impacted. Moreover, our brands and reputation could be harmed if we were to experience significant negative publicity;

•we rely on many different marketing channels to acquire and retain customers and to promote our brands and our products, and if we are not able to effectively acquire and retain customers via such channels then our business, financial condition, results of operations and prospects could be harmed;

•our business is subject to a variety of U.S. and foreign laws and regulations (including Colombia, Canada, Mexico and Peru, where we have business operations), many of which are unsettled and still developing, and our growth prospects depend on the legal status of real-money gaming in various jurisdictions;

•we are subject to taxation in numerous jurisdictions and changes in, or new interpretation of, tax laws, tax rulings or their application by tax authorities could result in additional tax liabilities and could materially affect our business, financial condition, results of operations and prospects;

•our growth prospects may suffer if we are unable to develop or maintain successful offerings, if we fail to pursue additional offerings or if we lose any of our key executives or other key employees;

•economic downturns and political and market conditions beyond our control, including a reduction in consumer discretionary spending and the effects of inflation and tariffs, could adversely affect our business, financial condition, results of operations and prospects;

•we rely on information technology and other systems and platforms (including reliance on third-party providers to validate the identity and location of our customers and to process deposits and withdrawals made by our customers), and any breach or disruption of such information technology could compromise our networks and the information stored there could be accessed, publicly disclosed, lost, corrupted or stolen;

•until fairly recently, we have had a history of losses (calculated in accordance with accounting principles generally accepted in the United States) and could start to incur losses again in the future;

•the timing, amount or duration of the Company’s stock repurchase program;

•our success in retaining or recruiting officers, key employees or directors;

•we license certain trademarks and domain names from Rush Street Gaming, LLC (“RSG”) and its affiliates, and RSG’s and its affiliates’ use of such trademarks and domain names, or failure to protect or enforce our intellectual property rights, could harm our business, financial condition, results of operations and prospects;

•we currently, and will likely continue to, rely on licenses and service agreements to use the intellectual property rights of related or third parties that are incorporated into or used in our products and services; and

•certain of our officers and directors may allocate their time to other businesses such as RSG and potentially have conflicts of interest with our business.

Due to the uncertain nature of these factors, management cannot assess the impact of each factor on the business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements. Any forward-looking statement speaks only as of the date on which such statement is made, and we undertake no obligation to update any of these statements to reflect events or circumstances occurring after the date of this Annual Report, except as required by applicable law. New factors may emerge, and it is not possible to predict all factors that may affect our business and prospects.

Limitations of Key Metrics and Other Data

The numbers for our key metrics, which include our monthly active users (“MAUs”) and average revenue per MAU (“ARPMAU”), are calculated using internal company data based on the activity of user accounts. While these numbers are based on what we believe to be reasonable estimates of our user base and activity levels for the applicable period of measurement, there are inherent challenges in measuring usage of our offerings across large online and mobile populations based in numerous jurisdictions. In addition, we continuously seek to improve our estimates of our user base and user activity, and such estimates may change due to improvements or changes in our methodology.

We regularly evaluate these metrics to estimate the number of “duplicate” accounts among our MAUs and remove the effects of such duplicate accounts on our key metrics. A duplicate account is one that a user maintains in addition to his or her principal account. Generally, duplicate accounts arise as a result of users signing up to use more than one of our brands (i.e., BetRivers, PlaySugarHouse and RushBet) or to use our offerings in more than one jurisdiction, for instance when a user lives in New Jersey but works in New York. The estimates of duplicate accounts are based on an internal review of a limited sample of accounts, and we apply significant judgment in making this determination. For example, to identify duplicate accounts we use data signals such as similar IP addresses or usernames. Our estimates may change as our methodologies evolve, including through the application of new data signals or technologies, which may allow us to identify previously undetected duplicate accounts and may improve our ability to evaluate a broader population of our users. Duplicate accounts are very difficult to measure, and it is possible that the actual number of duplicate accounts may vary significantly from our estimates.

Our data limitations may affect our understanding of certain details of our business. We regularly review our processes for calculating these metrics, and from time to time we may discover inaccuracies in our metrics or make adjustments to improve their accuracy, including adjustments that may result in the recalculation of our historical metrics. We believe that any such inaccuracies or adjustments are immaterial unless otherwise stated. In addition, our key metrics and related information and estimates, including the definitions and calculations of the same, may differ from those published by third parties or from similarly titled metrics of our competitors due to differences in operations, offerings, methodology and access to information.
