18 LEGAL DISCLAIMER FORWARD-LOOKING STATEMENTS. The financial results in this presentation reflect preliminary, unaudited results, which are not final until the Company’s quarterly report on Form 10-Q is filed. This presentation contains forward-looking statements regarding, among other things, our business plans; our expectations regarding our proposed transaction with First Busey Corporation (“Busey”); growth opportunities; expense control initiatives; anticipated expenses, cash requirements and sources of liquidity; capital allocation strategies and plans; and future financial performance. These statements are often, but not always, made through the use of words or phrases such as “positioned,” “growth,” “estimate,” “believe,” “plan,” “future,” “opportunity,” “optimistic,” “anticipate,” “target,” “expectations,” “expect,” “will,” “strategy,” “goal, “focused,” “guidance,” “foresee” and similar words or phrases of a future or forward-looking nature. The inclusion of forward-looking information herein should not be regarded as a representation by us or any other person that the future plans, estimates or expectations contemplated by us will be achieved. These forward-looking statements are not historical facts, and are based on current expectations, estimates and projections about our industry, management’s beliefs, certain assumptions made by management, and financial trends that may affect our financial condition, results of operations, business strategy or financial needs, many of which, by their nature, are inherently uncertain and beyond our control. Our actual results could differ materially from those anticipated in such forward-looking statements. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, estimates and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements due to a number of factors, including without limitation, the following: the possibility that the proposed transaction with Busey will not close when expected or at all because required regulatory, stockholder or other approvals are not received or other conditions to the closing are not satisfied on a timely basis or at all, or are obtained subject to conditions that are not anticipated (and the risk that required regulatory approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the proposed transaction); the possibility that the anticipated benefits of the proposed transaction will not be realized when expected or at all; the possibility that the parties may be unable to achieve expected synergies and operating efficiencies in the merger within the expected timeframes or at all and to successfully integrate CrossFirst’s operations and those of Busey; effects of the announcement, pendency or completion of the proposed transaction on the ability of CrossFirst to retain customers and retain and hire key personnel and maintain relationships with our suppliers, and on our operating results and business generally; uncertain or unfavorable business or economic conditions and any regulatory responses thereto, including uncertainty and volatility in the financial markets; possible slowing or recessionary economic conditions and continuing or increasing inflation; geographic concentration of our markets; changes in market interest rates that affect the pricing of our products and our net interest income; our ability to effectively execute our growth strategy and manage our growth, including entering new lines of business or offering new or enhanced services or products; fluctuations in the fair value of our investments; our ability to successfully manage our credit risk, particularly in our commercial real estate, energy and commercial-based loan portfolios, and the sufficiency of our allowance for credit losses; declines in the values of the real estate and other collateral securing loans in our portfolio; an increase in non-performing assets; borrower and depositor concentration risks; risks associated with originating Small Business Administration loans; our dependence on our management team, including our ability to attract, hire and retain key employees and their client and community relationships; our ability to raise and maintain sufficient liquidity and capital; competition from banks, credit unions, FinTech companies and other financial services providers; the effectiveness of our risk management framework; accounting estimates; our ability to maintain effective internal control over financial reporting; our ability to keep pace with technological changes; system failures, service denials, cyber incidents or other failures, disruptions or security breaches; employee error, employee or client misconduct, fraud committed against the Company or our clients, or incomplete or inaccurate information about clients and counterparties; disruptions to our business caused by our third-party service providers; our ability to maintain our reputation; environmental liability or failure to comply with regulatory requirements affecting foreclosed properties; costs and effects of litigation, investigations or similar matters to which we may be subject; risk exposure from transactions with financial counterparties; severe weather, natural disasters, pandemics or other health crises, acts of war or terrorism, climate change and responses thereto, or other external events; compliance with (and changes in) laws, rules, regulations, interpretations or policies relating to or affecting financial institutions, including stringent capital requirements, higher FDIC insurance premiums and assessments, consumer protection laws and privacy laws and accounting, tax, trade, monetary and fiscal matters, including the policies of the Federal Reserve and as a result of government initiatives; systemic risks across the banking industry associated with the soundness of other financial institutions; volatility in our stock price and other risks associated with our common stock; changes in our dividend or share repurchase policies and practices or other external events. These and other factors that could cause results to differ materially from those described in the forward-looking statements, as well as a discussion of the risks and uncertainties that may affect our business, can be found in our Annual Report on Form 10-K, our Quarterly Reports on Form 10-Q and in other filings we make with the Securities and Exchange Commission. These forward-looking statements are made as of the date hereof, and we disclaim any obligation to update any forward-looking statement or to publicly announce the results of any revisions to any of the forward-looking statements included herein, except as required by law.

This presentation references certain market, industry and demographic data, forecasts and other statistical information. We have obtained this data, forecasts and information from various independent, third party industry sources and publications. Nothing in the data, forecasts or information used or derived from third party sources should be construed as advice. Some data and other information are also based on our good faith estimates, which are derived from our review of industry publications and surveys and independent sources. We believe that these sources and estimates are reliable but have not independently verified them. Statements as to our market position are based on market data currently available to us. Although we are not aware of any misstatements regarding the economic, employment, industry and other market data presented herein, these estimates involve inherent risks and uncertainties and are based on assumptions that are subject to change. ABOUT NON-GAAP FINANCIAL MEASURES. In addition to disclosing financial measures determined in accordance with U.S. generally accepted accounting principles (GAAP), we disclose non-GAAP financial measures, including “adjusted net income”, “adjusted diluted earnings per common share”, “tangible common stockholders’ equity”, “tangible book value per common share”, “adjusted return on average assets (ROAA)”, “adjusted return on average common equity (ROCE)”, “adjusted efficiency ratio – fully tax equivalent (FTE),” “pre-tax pre-provision (PTPP) profit” and “adjusted non-interest expense.” We consider the use of select non-GAAP financial measures and ratios to be useful for financial and operational decision making and useful in evaluating period-to-period comparisons. We believe that these non-GAAP financial measures provide meaningful supplemental information regarding our performance by excluding certain expenditures or gains that we believe are not indicative of our primary business operating results. We believe that management and investors benefit from referring to these non-GAAP financial measures in assessing our performance and when planning, forecasting, analyzing and comparing past, present and future periods. These non-GAAP financial measures should not be considered a substitute for financial information presented in accordance with GAAP and should not be relied on alone as measures of our performance. The non-GAAP financial measures we present may differ from non-GAAP financial measures used by our peers or other companies. We compensate for these limitations by providing the equivalent GAAP measures whenever we present the non-GAAP financial measures and by including a reconciliation of the impact of the components adjusted for in the non-GAAP financial measure so that both measures and the individual components may be considered when analyzing our performance. A reconciliation of non-GAAP financial measures to the comparable GAAP financial measures is provided above under “Non-GAAP Reconciliations.”
