2 24Q23 Earnings Investor Presentation First Busey Corporation | Ticker: BUSE This presentation may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of operations, plans, objectives, future performance and business of First Busey Corporation (“Busey”) and Merchants and Manufacturers Bank Corporation (“M&M”). Forward-looking statements, which may be based upon beliefs, expectations and assumptions of Busey’s and Merchants’ management and on information currently available to management, are generally identifiable by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “intend,” “estimate,” “may,” “will,” “would,” “could,” “should” or other similar expressions. Additionally, all statements in this presentation, including forward-looking statements, speak only as of the date they are made, and neither Busey nor M&M undertakes any obligation to update any statement in light of new information or future events. A number of factors, many of which are beyond the ability of Busey and M&M to control or predict, could cause actual results to differ materially from those in Busey’s forward-looking statements. These factors include, among others, the following: (1) the possibility that any of the anticipated benefits of the proposed transaction between Busey and M&M will not be realized or will not be realized within the expected time period; (2) the risk that integration of operations of M&M with those of Busey will be materially delayed or will be more costly or difficult than expected; (3) the inability to complete the proposed transaction due to the failure of the required approval of M&M’s stockholders; (4) the failure to satisfy other conditions to completion of the proposed transaction, including receipt of required regulatory and other approvals; (5) the failure of the proposed transaction to close for any other reason; (6) the effect of the announcement of the transaction on customer relationships and operating results; (7) the possibility that the transaction may be more expensive to complete than anticipated, including as a result of unexpected factors or events; (8) the strength of the local, state, national, and international economy (including effects of inflationary pressures and supply chain constraints); (9) the economic impact of any future terrorist threats or attacks, widespread disease or pandemics (including the Coronavirus Disease 2019 pandemic), or other adverse external events that could cause economic deterioration or instability in credit markets (including Russia’s invasion of Ukraine and the Israeli-Palestinian conflict); (10) changes in state and federal laws, regulations, and governmental policies concerning Busey's or M&M's general business (including changes in response to the recent failures of other banks); (11) changes in accounting policies and practices; (12) changes in interest rates and prepayment rates of Busey’s or M&M's assets (including the impact of the London Interbank Offered Rate phase-out and the recent and potential additional rate increases by the Federal Reserve); (13) increased competition in the financial services sector (including from non-bank competitors such as credit unions and fintech companies) and the inability to attract new customers; (14) changes in technology and the ability to develop and maintain secure and reliable electronic systems; (15) the loss of key executives or associates; (16) changes in consumer spending; (17) unexpected results of acquisitions, including the acquisition of M&M and the performance of M&M’s life equity loan business; (18) unexpected outcomes of existing or new litigation involving Busey or M&M; (19) fluctuations in the value of securities held in Busey’s or M&M’s securities portfolio; (20) concentrations within Busey’s or M&M’s loan portfolio, large loans to certain borrowers, and large deposits from certain clients; (21) the concentration of large deposits from certain clients who have balances above current FDIC insurance limits and may withdraw deposits to diversify their exposure; (22) the level of non-performing assets on Busey’s or M&M’s balance sheets; (23) interruptions involving information technology and communications systems or third-party servicers; (24) breaches or failures of information security controls or cybersecurity-related incidents; and (25) the economic impact of exceptional weather occurrences such as tornadoes, hurricanes, floods, blizzards, and droughts. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements.

3 34Q23 Earnings Investor Presentation First Busey Corporation | Ticker: BUSE Non-GAAP Financial Information This presentation contains certain financial information determined by methods other than U.S. Generally Accepted Accounting Principles (“GAAP”). Management uses these non-GAAP measures, together with the related GAAP measures, in analysis of Busey’s performance and in making business decisions, as well as for comparison to the Company’s peers. Busey believes the adjusted measures are useful for investors and management to understand the effects of certain non-core and non-recurring noninterest items and provide additional perspective on the Company’s performance over time. A reconciliation to what management believes to be the most directly comparable GAAP financial measures—specifically, net interest income, total noninterest income, net security gains and losses, and total noninterest expense in the case of pre-provision net revenue, adjusted pre-provision net revenue, pre-provision net revenue to average assets, and adjusted pre-provision net revenue to average assets; net income in the case of adjusted net income, adjusted diluted earnings per share, adjusted return on average assets, average tangible common equity, return on average tangible common equity, and adjusted return on average tangible common equity; net income and net security gains and losses in the case of net income excluding net securities gains and losses and diluted earnings per share excluding net securities gains and losses; net interest income in the case of adjusted net interest income and adjusted net interest margin; net interest income, total noninterest income, and total noninterest expense in the case of adjusted noninterest expense, noninterest expense excluding non-operating adjustments, adjusted core expense, efficiency ratio, adjusted efficiency ratio, and adjusted core efficiency ratio; total assets and goodwill and other intangible assets in the case of tangible assets; total stockholders’ equity in the case of tangible book value per common share; total assets and total stockholders’ equity in the case of tangible common equity and tangible common equity to tangible assets; portfolio loans in the case of core loans and core loans to portfolio loans; total deposits in the case of core deposits and core deposits to total deposits; and portfolio loans and total deposits in the case of core loans to core deposits—appears in the appendix of this presentation. These non-GAAP disclosures have inherent limitations and are not audited. They should not be considered in isolation or as a substitute for operating results reported in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Tax effected numbers included in these non-GAAP disclosures are based on estimated statutory rates or effective rates as appropriate.
