SIGNIFICANT ACCOUNTING POLICIES Nature of Operations First Busey Corporation, a Nevada corporation organized in 1980, is a $ 11.9 billion financial holding company headquartered in Champaign, Illinois. Busey’s common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.” First Busey operates and reports its business in three segments: Banking, Wealth Management, and FirsTech. • The Banking operating segment provides a full range of banking services to individual and corporate customers through its banking center network in Illinois; the St. Louis, Missouri metropolitan area; southwest Florida; and Indianapolis, Indiana. • The Wealth Management operating segment provides a full range of asset management, investment, brokerage, fiduciary, philanthropic advisory, tax preparation, and farm management services to individuals, businesses, and foundations. • The FirsTech operating segment provides comprehensive and innovative payment technology solutions including online, mobile, and voice-recognition bill payments; money management and credit card networks; direct debit services; lockbox remittance processing for payments made by mail; and walk-in payments. FirsTech also provides additional tools to help clients with billing, reconciliation, bill reminders, and treasury services. For additional information about First Busey's operating segments, see “ Note 15. Operating Segments and Related Information .” Basis of Financial Statement Presentation These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in Busey's 2023 Annual Report . These interim unaudited consolidated financial statements serve to update our 2023 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements. We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations. In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period. Use of Estimates In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, Busey’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of debt securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL. 12 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Impact of Recently Adopted Accounting Standards In March 2023, the FASB issued ASU 2023‑02 “Investments—Equity Method and Joint Ventures (Topic 323),” permitting an election to use the proportional amortization method to account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits, regardless of the tax credit program from which the income tax credits are received, provided that certain conditions are met. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense. Busey adopted this standard on a modified retrospective basis on January 1, 2024. Upon adoption, Busey recorded an after-tax decrease to retained earnings of $ 1.4 million for the cumulative effect of adopting ASU 2023‑02. This transition adjustment included a $ 2.4 million decrease in other assets, a $ 0.5 million decrease in other liabilities, and a $ 0.5 million increase in deferred tax assets. In March 2023, the FASB issued ASU 2023‑01 “Leases (Topic 842): Common Control Arrangements,” which requires amortization over the useful life of leasehold improvements (not the lease term) when the lease is between entities under common control, and any value of such leasehold improvements remaining at the end of the lease term is to be accounted for as a transfer between entities under common control. Busey adopted this standard on a prospective basis on January 1, 2024. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations. In June 2022, the FASB issued ASU 2022-03 “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which clarifies that contractual restrictions on the sale of equity securities are not considered in measuring the fair value of those equity securities, and further that contractual sale restrictions cannot be recognized and measured as a separate unit of account. Busey adopted this standard on a prospective basis on January 1, 2024. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations. Recently Issued Accounting Standards Not Yet Adopted In March 2024, the FASB issued ASU 2024-01 “Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards” to clarify that certain “profits interests” are within the scope of Topic 718 by amending the language and providing illustrative examples on how the scope guidance in paragraph 718-10-15-3 should be applied. This update is intended to improve clarity of the accounting standards codification, not to change the guidance. This update may be applied on a retrospective or prospective basis and will be effective for Busey for annual and interim periods beginning January 1, 2025. Early adoption is permitted. Busey is currently evaluating the potential effects of adoption of this ASU on its financial position and results of operations. In December 2023, the FASB issued ASU 2023‑09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires more detailed disclosures of income taxes paid net of refunds received, income from continuing operations before income tax expense or benefit, and income tax expense from continuing operations. This standard is to be applied on a prospective basis, with retrospective application permitted, and will be effective for Busey for annual reporting periods beginning with the fiscal year ending December 31, 2025. Busey does not expect adoption of this standard to have a material impact on its financial position or results of operations. 13 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) In November 2023, the FASB issued ASU 2023‑07 “Segment Reporting Topic 820): Improvements to Reportable Segment Disclosures” requiring enhanced disclosures related to significant segment expenses. This standard is to be applied on a retrospective basis and is effective for Busey for annual reporting periods beginning with the fiscal year ending December 31, 2024, and for interim reporting periods within fiscal years starting January 1, 2025. Busey does not expect adoption of this standard to have a material impact on the Company’s financial position or results of operations. In October 2023, the FASB issued ASU 2023‑06 “Disclosure Improvements: Codification Amendments in Response to the SEC’s Disclosure Update and Simplification Initiative” which aligns certain GAAP disclosure requirements with the SEC’s disclosure requirements, in order to better facilitate comparisons between entities that are subject to the SEC’s existing disclosures with entities that were not previously subject to the SEC’s requirements. Amendments in this update should be applied prospectively, and the effective date for Busey for each amendment in this ASU will be the date on which the SEC removes the related disclosure from Regulation S‑X or Regulation S‑K. Early adoption is prohibited. Busey does not expect adoption of this standard to have a material impact on its financial position or results of operations. Subsequent Events Busey has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. Busey issued a Form 8‑K on April 1 , 202 4 , announcing completion of its acquisition of M&M on that date. Merger consideration paid to M&M common stockholders was comprised of an aggregate of 1,429,304 shares of Busey common stock and an aggregate of $ 12.2 million in cash. For additional information about Busey’s acquisition of M&M, see “ Not e. 16 Acquisition .” There were no other significant events subsequent to the quarter ended March 31, 2024, through the filing date of these unaudited consolidated financial statements. 14 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 2.

Unless part of a corporate strategy or restructuring plan, Busey does not intend to sell securities that are in an unrealized or unrecognized loss position, and it is more likely than not that the Company will recover the amortized cost prior to being required to sell the debt securities. Full collection of the amounts due according to the contractual terms of the debt securities is expected; therefore, no ACL was recorded in relation to debt securities, and the impairment related to noncredit factors on debt securities available for sale is recognized in AOCI, net of applicable taxes. As of March 31, 2024, Busey did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of Busey’s stockholders’ equity. 20 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 3. PORTFOLIO LOANS Loan Categories Busey’s lending can be summarized in two primary categories: commercial and retail. Lending is further classified into five primary areas of loans: C&I and other commercial loans, commercial real estate loans, real estate construction loans, retail real estate loans, and retail other loans. Distributions of the loan portfolio by loan category and class is presented in the following table (dollars in thousands) : As of March 31, 2024 December 31, 2023 Commercial loans C&I and other commercial $ 1,828,711 $ 1,835,994 Commercial real estate 3,331,670 3,337,337 Real estate construction 445,860 461,717 Total commercial loans 5,606,241 5,635,048 Retail loans Retail real estate 1,708,663 1,720,455 Retail other 273,173 295,531 Total retail loans 1,981,836 2,015,986 Total portfolio loans 7,588,077 7,651,034 ACL ( 91,562 ) ( 91,740 ) Portfolio loans, net $ 7,496,515 $ 7,559,294 Net deferred loan origination costs included in the balances above were $ 13.4 million as of March 31, 2024, compared to $ 13.5 million as of December 31, 2023. Net accretable purchase accounting adjustments included in the balances above reduced loans by $ 4.3 million as of March 31, 2024, and $ 4.5 million as of December 31, 2023. Busey did not purchase any retail real estate loans during the three months ended March 31, 2024 or 2023. Pledged Loans The principal balance of loans Busey has pledged as collateral to the FHLB and Federal Reserve Bank for liquidity as set forth in the table below (dollars in thousands) : As of March 31, 2024 December 31, 2023 Pledged loans FHLB $ 4,821,485 $ 4,865,481 Federal Reserve Bank 724,971 722,914 Total pledged loans $ 5,546,456 $ 5,588,395 21 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Risk Grading Busey utilizes a loan grading scale to assign a risk grade to all of its loans. A description of the general characteristics of each grade is as follows: • Pass – This category includes loans that are all considered acceptable credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that meet or exceed industry standards. • Watch – This category includes loans that warrant a higher-than-average level of monitoring to ensure that weaknesses do not cause the inability of the credit to perform as expected. These loans are not necessarily a problem due to other inherent strengths of the credit, such as guarantor strength, but have above average concern and monitoring. • Special mention – This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect Busey’s credit position at some future date. • Substandard – This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that Busey will sustain some loss if the deficiencies are not corrected. • Substandard non-accrual – This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine. All loans are graded at their inception. Commercial lending relationships that are $ 1.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $ 1.0 million are included in a portfolio review at least annually. Commercial loans greater than $ 0.35 million that have a grading of special mention or worse are typically reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more frequent review. 22 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The

These estimates are affected by changing economic conditions and the economic prospects of borrowers. Collateral dependent loans are loans in which repayment is expected to be provided solely by the operation or sale of the underlying collateral and there are no other available and reliable sources of repayment. Loans are written down to the lower of cost or fair value of the underlying collateral, less estimated costs to sell. Busey had $ 14.2 million and $ 6.1 million of collateral dependent loans secured by real estate or business assets as of March 31, 2024, and December 31, 2023, respectively. Foreclosures As of March 31, 2024, Busey had $ 0.9 million of residential real estate loans in the process of foreclosure.

Portfolio loans are charged off against the ACL when management believes the uncollectibility of a loan balance is confirmed. Recoveries will be recognized up to the aggregate amount of previously charged-off balances. The ACL is established through the provision for credit loss charged to income. Management estimates the ACL balance using relevant available information from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of Busey’s historical loss experience beginning in 2010. Due to the continued economic uncertainty in the markets in which the Company operates, Busey will continue to utilize a forecast period of 12 months with an immediate reversion to historical loss rates beyond this forecast period in its ACL estimate. 30 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The following tables summarize activity in the ACL attributable to each loan class.

The loans had an annual interest rate of 1.75 % plus the one-month LIBOR rate. On April 30, 2022, the agreement was amended, effecting an extension of the termination date for the revolving line of credit to April 30, 2023, and providing for the transition from a LIBOR-indexed interest rate to a SOFR-indexed interest rate. Under the terms of the amendment, the loans now have an annual interest rate of 1.80 % plus the one-month forward-looking term rate based on SOFR. The agreement has subsequently been amended twice to extend the termination date for the revolving line of credit, which is currently April 30, 2025. During the first quarter of 2024, Busey paid the full $ 30.0 million balance remaining on the Term Loan, at which time the Term Loan carried interest at a rate of 7.13 %.

Unamortized debt issuance costs related to Busey’s subordinated notes are presented in the following table (dollars in thousands) : As of March 31, 2024 December 31, 2023 Unamortized debt issuance costs Subordinated notes issued in 2020 $ 610 $ 735 Subordinated notes issued in 2022 1,290 1,383 Total unamortized debt issuance costs $ 1,900 $ 2,118 NOTE 7. REGULATORY CAPITAL Busey and Busey Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on Busey's consolidated financial statements. Capital amounts and classification also are subject to qualitative judgments by regulators about components, risk weightings, and other factors. 37 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Banking regulations identify five capital categories for insured depository institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. As of March 31, 2024, and December 31, 2023, all capital ratios of Busey and Busey Bank exceeded well capitalized levels under the applicable regulatory capital adequacy guidelines. Management believes that no events or changes have occurred subsequent to March 31, 2024, that would change this designation. Current Expected Credit Loss Model On August 26, 2020, the FDIC and other federal banking agencies adopted a final rule which provided banking organizations that adopted CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital and to phase in the aggregate impact of the deferral on regulatory capital over a subsequent three-year period. Under this final rule, because Busey elected to use the deferral option, the regulatory capital impact of our transition adjustments recorded on January 1, 2020, arising from the adoption of CECL, was deferred for two years. In addition, 25 percent of the ongoing impact of CECL on our ACL, retained earnings, and average total consolidated assets from January 1, 2020, through the end of the two-year deferral period, each as reported for regulatory capital purposes, has been added to the deferred transition amounts (“adjusted transition amounts”) and deferred for the two-year period. On January 1, 2022, at the conclusion of the two-year period, the adjusted transition amounts began to be phased-in for regulatory capital purposes at a rate of 25 percent per year, with the phased-in amounts included in regulatory capital at the beginning of each year.

The Basel III Rule introduced a capital conservation buffer, composed entirely of common equity Tier 1 capital, which is added to the minimum risk-weighted asset ratios. The capital conservation buffer is not a minimum capital requirement; however, banking institutions with a ratio of common equity Tier 1 capital to risk-weighted assets below the capital conservation buffer will face constraints on dividends, equity repurchases, and discretionary bonus payments based on the amount of the shortfall. In order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments, banking institutions must maintain minimum ratios of (1) common equity Tier 1 capital to risk-weighted assets of at least 7.0%, (2) Tier 1 capital to risk-weighted assets of at least 8.5%, and (3) total capital to risk-weighted assets of at least 10.5%. 39 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 8. TAX CREDIT AND OTHER INVESTMENTS IN UNCONSOLIDATED ENTITIES Busey has invested in certain tax-advantaged projects promoting affordable housing, new markets, and historic rehabilitation. These investments are designed to generate returns primarily though the realization of federal and state income tax credits and other tax benefits, such as tax deductions from operating losses of the investments, over specified time periods. These investments are considered to be variable interest entities, and are accounted for under the equity, deferral, or proportional amortization practical expedient methods, as appropriate. Busey is not required to consolidate variable interest entities in which it has concluded it does not have a controlling financial interest, and is not the primary beneficiary. Busey’s maximum exposure to loss related to its investments in these unconsolidated variable interest entities is limited to the carrying amount of the investment, net of any unfunded capital commitments and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. Busey believes potential losses from these investments are remote. In addition, Busey has private equity investments, which are primarily in funds that invest in small businesses across diverse sectors including, but not limited to, financial technology, business services, manufacturing, agribusiness, healthcare, software as a service, and environmental, or supporting the preservation of affordable housing. Busey’s investments in these unconsolidated entities and related unfunded investment obligations are reflected in other assets and other liabilities on the Consolidated Balance Sheets (Unaudited), and are summarized in the table below for the periods indicated (dollars in thousands) : As of Location March 31, 2024 December 31, 2023 Investments in unconsolidated entities Funded investments Other assets $ 64,516 $ 68,516 Unfunded investments Other assets 56,362 58,552 Investments in unconsolidated entities $ 120,878 $ 127,068 Unfunded investment obligations Other liabilities $ 56,362 $ 58,552 Upon adoption of ASU 2023-02 on January 1, 2024, Busey elected to apply the proportional amortization method in accounting for investments in tax-advantaged projects. Income tax credits and other tax benefits, net of investment amortization, were included as a component of our estimated annual effective tax rate used for the calculation of income taxes presented in the Consolidated Statements of Income (Unaudited). These income tax credits and other benefits, along with the investment amortization, are presented in the table below (dollars in thousands) : Three Months Ended March 31, 2024 Tax effects of investments in tax-advantaged projects Income tax credits and other tax benefits $ 4,101 Amortization of investments in tax-advantaged projects 3,647 40 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 9.

A description of the 2020 Equity Plan, as originally approved, can be found in Appendix A within Busey’s Proxy Statement for the 2020 Annual Meeting of Stockholders filed on April 9, 2020 . An amendment and restatement of the 2020 Equity Plan was approved by stockholders at the 2023 Annual Meeting of Stockholders. Terms of the amended and restated 2020 Equity Plan are substantially identical to those of the originally approved 2020 Equity Plan, other than a 1,350,000 increase in the number of shares authorized for issuance under the plan. More information can be found in Appendix A within Busey’s Proxy Statement for the 2023 Annual Meeting of Stockholders filed on April 14, 2023 . Busey has granted RSU, PSU, and DSU awards under the terms of the 2020 Equity Plan. Upon vesting and delivery, shares are expected, though not required, to be issued from treasury stock. There were 1,333,769 shares available for issuance under the 2020 Equity Plan as of March 31, 2024. A description of RSU, PSU, and DSU awards granted in 2024 under the terms of the 2020 Equity Plan is provided below. Further information related to awards granted in prior years has been presented in the Annual Reports previously filed with the SEC corresponding to the year of each award grant. RSU Awards Busey grants RSU awards to members of management periodically throughout the year. RSU awards are stock-based awards for which vesting is conditional upon meeting established service criteria. Each RSU is equivalent to one share of Busey’s common stock. Busey’s RSUs have requisite service periods ranging from one year to five years , and are subject to accelerated vesting upon eligible retirement from Busey. Recipients earn quarterly dividend equivalents on their respective RSUs, which entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances. On March 20, 2024, under the terms of the 2020 Equity Plan, Busey granted 189,179 RSUs to members of management. The grant date fair value of the award was $ 4.4 million, which will be recognized as compensation expense over the requisite service period ranging from one year to five years . The terms of these awards included an accelerated vesting provision upon eligible retirement from Busey, after a one-year minimum requisite service period. Subsequent to the requisite service period, the awards will become 100 % vested. 41 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) A summary of changes in Busey’s RSU awards for the three months ended March 31, 2024, is as follows: RSU Awards Shares Weighted- Average Grant Date Fair Value Nonvested at December 31, 2023 1,041,444 $ 22.05 Granted 189,179 23.35 Dividend equivalents earned 10,219 24.46 Vested ( 7,681 ) 23.23 Forfeited ( 5,347 ) 23.38 Nonvested at March 31, 2024 1,227,814 22.25 PSU Awards Busey grants PSU awards to members of management periodically throughout the year. PSU awards are stock-based awards for which vesting is conditional upon meeting established performance criteria. Each PSU is equivalent to one share of Busey’s common stock. The number of PSUs that ultimately vest will be determined based on the extent to which market or other performance goals are achieved. Busey’s PSUs are subject to accelerated service-based vesting conditions upon eligible retirement from Busey. After performance determination, dividend equivalents are compounded based upon the updated PSU balances at each dividend date during the performance period. On March 20, 2024, under the terms of the 2020 Equity Plan, Busey granted a target of 94,604 PSUs with a maximum award of 151,366 units. The actual number of units issued at the vesting date could range from 0 % to 160 % of the initial grant, depending on attaining a market-based total stockholder return performance goal. The estimated grant date fair value of the award was $ 2.2 million, which will be recognized in compensation expense over the performance period ending December 31, 2026. Busey expects to finalize the grant date fair value of these awards in the second quarter of 2024. On March 20, 2024, under the terms of the 2020 Equity Plan, Busey granted a target of 94,604 PSUs with a maximum award of 151,366 units. The actual number of units issued at the vesting date could range from 0 % to 160 % of the initial grant, depending on attaining an adjusted return on average tangible common equity performance goal. The grant date fair value of the award was $ 2.2 million, which will be recognized in compensation expense over the performance period ending December 31, 2026. The actual amount of compensation expense recognized for these awards may vary, subject to achievement of the performance goal. A summary of changes in Busey’s PSU awards for the three months ended March 31, 2024, is as follows: PSU Awards Shares 1 Weighted- Average Grant Date Fair Value Nonvested at December 31, 2023 341,700 $ 22.67 Granted 189,208 23.35 Dividend equivalents earned 2 4,264 22.95 Vested 2 ( 4,264 ) 22.95 Forfeited ( 1,754 ) 22.76 Nonvested at March 31, 2024 529,154 $ 22.91 ___________________________________________ 1.

PSUs granted in 2021 vested on December 31, 2023, with performance determination and settlement activity in the first quarter of 2024. Final performance was determined to be at 50% of target. 42 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) DSU Awards Busey grants DSU awards to its directors and advisory directors. DSU awards are stock-based awards with a deferred settlement date. Each DSU is equivalent to one share of Busey’s common stock. DSUs vest over a one-year period following the grant date. Under the 2020 Equity Plan, DSUs are generally subject to the same terms as RSUs, except that following vesting of DSUs, settlement occurs within 30 days following the earlier of separation from the board or a change in control of the Company. After vesting and prior to delivery, DSUs will continue to earn dividend equivalents. On March 20, 2024, under the terms of the 2020 Equity Plan, Busey granted 35,847 DSUs to directors and advisory directors. The grant date fair value of the award totaled $ 0.8 million and will be recognized as compensation expense over the requisite service period of one year . Subsequent to the requisite service period, the awards will become 100 % vested.

The purpose of the 2021 ESPP is to provide a means through which our employees may acquire a proprietary interest in Busey by purchasing shares of our common stock at a 15 % discount through voluntary payroll deductions, to assist us in retaining the services of our employees and securing and retaining the services of new employees, and to provide incentives for our employees to exert maximum efforts toward our success. The 2021 ESPP initially reserved for issuance and purchase an aggregate of 600,000 shares of Busey’s common stock. The first offering under the 2021 ESPP began on July 1, 2021. There were 429,074 shares available for issuance under the 2021 ESPP as of March 31, 2024.

NOTE 10. OUTSTANDING COMMITMENTS AND CONTINGENT LIABILITIES Legal Matters Busey is a party to legal actions which arise in the normal course of its business activities. Legal and administrative proceedings are subject to inherent uncertainties, and while unfavorable outcomes could occur, Busey does not believe at this time that any potential liabilities relating to pending or potential legal matters are likely to have a material impact on Busey's results of operations or financial position. 44 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Credit Commitments and Contingencies A summary of the contractual amount of Busey’s exposure to off-balance-sheet risk relating to the Company’s commitments to extend credit and standby letters of credit follows (dollars in thousands) : As of March 31, 2024 December 31, 2023 Financial instruments whose contract amounts represent credit risk Commitments to extend credit $ 2,118,621 $ 2,132,500 Standby letters of credit 46,967 43,996 Total commitments $ 2,165,588 $ 2,176,496 Franchise Tax Matter In 2021, Busey received an inquiry from the Illinois Secretary of State (“ISOS”), pursuant to which the ISOS asked for additional information regarding certain of our franchise tax filings and the calculation of amounts due thereunder. The franchise tax is established by the Illinois Business Corporation Act (“BCA”) 805 ILCS 5/1 et seq., and is a tax imposed on foreign and domestic corporations for the privilege of conducting business in Illinois. Busey has been cooperating with the inquiry and has agreed to prepare additional BCA forms requested by the ISOS, with a full reservation of rights by Busey, including seeking judicial relief, if necessary, with respect to any potential dispute regarding Busey’s preparation of the BCA forms and the calculation of the franchise taxes due. Where a loss is believed to be reasonably possible, but not probable, or the loss cannot be reasonably estimated, as is the case with this matter, no accrual is required. It is reasonably possible that this matter could require us to pay additional taxes, including potential penalties and interest, or make other expenditures or accrue liabilities in amounts that could not be reasonably estimated as of March 31, 2024. If the likelihood of potential liabilities elevates, requiring an accrual, the potential future liabilities could be material in the period(s) in which they are recorded. NOTE 11. DERIVATIVE FINANCIAL INSTRUMENTS Busey utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. Additionally, Busey enters into derivative financial instruments, including interest rate lock commitments issued to residential loan customers for loans that will be held for sale; forward sales commitments to sell residential mortgage loans to investors; and interest rate swaps, risk participation agreements, and foreign currency exchange contracts with customers and other third parties. See “ Note 12: Fair Value Measurements ” for further discussion of the fair value measurement of such derivatives. To secure its obligations under derivative contracts, Busey pledged cash and held collateral as follows (dollars in thousands) : As of March 31, 2024 December 31, 2023 Cash pledged to secure obligations under derivative contracts $ 34,210 $ 34,210 Collateral held to secure obligations under derivative contracts 24,860 19,280 45 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Derivative Instruments Designated as Hedges Busey entered into derivative instruments designated as cash flow hedges. For a derivative instrument that is designated and qualifies as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in fair value of components excluded from the assessment of effectiveness are recognized in current earnings. Interest Rate Swaps Designated as Cash Flow Hedges Interest rate swaps with notional amounts totaling $ 450.0 million as of March 31, 2024, and $ 350.0 million as of December 31, 2023, were designated as cash flow hedges. Busey entered into one $ 50.0 million interest rate swap to hedge the risks of variability in cash flows for future interest payments attributable to changes in the 3-month CME Term SOFR benchmark interest rate on Busey’s junior subordinated debt owed to unconsolidated trusts (Debt Swap). In addition, Busey entered into one $ 300.0 million receive fixed pay floating interest rate swap to reduce Busey’s asset sensitivity (Prime Loan Swap). Duration was added to our loan portfolio by fixing a portion of floating prime-based loans. Interest rates had risen above their historical lows allowing Busey to lock in a portion of its loan portfolio to reduce asset sensitivity while creating a more stable margin in a volatile rate market. These hedges were determined to be highly effective during the period, and Busey expects its hedges to remain highly effective during the remaining terms of the swaps. Further, in 2024 Busey entered into one $ 100.0 million one year forward-starting SOFR-based receive-fixed pay-floating interest rate swap, with an effective date of March 5, 2025, to reduce Busey’s asset sensitivity (SOFR Loan Swap). Changes in fair value were recorded net of tax in OCI. 46 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) A summary of the interest-rate swaps designated as cash flow hedges is presented below (dollars in thousands) : As of Location March 31, 2024 December 31, 2023 Debt Swap Notional amount $ 50,000 $ 50,000 Weighted average fixed pay rates 1.79 % 1.79 % Weighted average variable 3-month Fallback Rate (SOFR) receive rates 5.62 % 5.61 % Weighted average maturity 0.46 years 0.71 years Prime Loan Swap Notional amount $ 300,000 $ 300,000 Weighted average fixed receive rates 4.81 % 4.81 % Weighted average variable Prime pay rates 8.50 % 8.50 % Weighted average maturity 4.85 years 5.10 years SOFR Loan Swap Notional amount $ 100,000 $ — Weighted average fixed receive rates 3.72 % — Weighted average maturity 4.93 years — Gross aggregate fair value of the swaps Gross aggregate fair value of swap assets Other assets $ 1,178 $ 1,293 Gross aggregate fair value of swap liabilities Other liabilities 30,303 25,411 Balances carried in AOCI Unrealized gains (losses) on cash flow hedges, net of tax AOCI $ ( 20,272 ) $ ( 16,694 ) Busey expects to reclassify unrealized gains and losses from OCI to interest income and interest expense as shown in the following table, during the next 12 months (dollars in thousands) . Amounts actually recognized could differ from these expectations due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to March 31, 2024. As of March 31, 2024 Unrealized gains (losses) in OCI expected to be recognized in income Unrealized losses expected to be reclassified from OCI to interest income $ ( 952 ) Unrealized gains expected to be reclassified from OCI to interest expense 483 Net unrealized gains (losses) in OCI expected to be recognized in net interest income $ ( 469 ) 47 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Interest expense recorded on these swap transactions was as follows for the periods presented (dollars in thousands) : Three Months Ended March 31, 2024 2023 Interest on swap transactions Increase (decrease) in interest income on swap transactions $ ( 2,796 ) $ ( 2,192 ) (Increase) decrease in interest expense on swap transactions 483 383 Net increase (decrease) in net interest income on swap transactions $ ( 2,313 ) $ ( 1,809 ) The following table reflects the net gains (losses) relating to cash flow derivative instruments that were recorded in AOCI and the Consolidated Statements of Income (Unaudited) during the periods presented (dollars in thousands) : Three Months Ended March 31, 2024 2023 Unrealized gains (losses) on cash flow hedges Net gain (loss) recognized in OCI, net of tax $ ( 5,232 ) $ 3,050 (Gain) loss reclassified from OCI to interest income, net of tax 1,999 1,567 (Gain) loss reclassified from OCI to interest expense, net of tax ( 345 ) ( 274 ) Net change in unrealized gains (losses) on cash flow hedges, net of tax $ ( 3,578 ) $ 4,343 Derivative Instruments Not Designated as Hedges Interest Rate Swaps Not Designated as Hedges Busey may offer derivative contracts to its customers in connection with their risk management needs. Busey manages the risk associated with these contracts by entering into equal and offsetting derivative agreements with third-party dealers. These contracts supported variable rate, commercial loan relationships totaling $ 678.3 million as of March 31, 2024, and $ 663.1 million as of December 31, 2023. These derivatives generally worked together as an economic interest rate hedge, but Busey did not designate them for hedge accounting treatment. Consequently, changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Under these risk participation agreements, Busey purchased a portion of the credit exposure, paying an up-front fee, and will receive a payment from the counterparty if the loan customer defaults on its obligations. Busey also entered into a risk participation agreement under which Busey sold a portion of its credit exposure, receiving an up-front fee, and will be required to make a payment to the counterparty if the loan customer defaults on its obligations. 49 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The notional amount of the risk participation agreements reflect Busey's pro-rata share of the derivative instrument, consistent with its share of the related participated loan.

Forward Sales Commitments Busey economically hedges mortgage loans held for sale and interest rate lock commitments issued to its residential loan customers related to loans that will be held for sale by obtaining corresponding forward sales commitments with an investor to sell the loans at an agreed-upon price at the time the interest rate locks are issued to the customers. Forward sales commitments that meet the definition of derivative financial instruments under ASC Topic 815 “Derivatives and Hedging” are carried at their fair values in other assets or other liabilities in the Consolidated Balance Sheets (Unaudited). While such forward sales commitments generally served as an economic hedge to mortgage loans held for sale and interest rate lock commitments, Busey did not designate them for hedge accounting treatment. Changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to current earnings during the period in which the changes occurred. 50 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Amounts and fair values of mortgage banking derivatives included in the Consolidated Balance Sheets (Unaudited) are summarized as follows (dollars in thousands) : As of March 31, 2024 As of December 31, 2023 Location Notional Amount Fair Value Notional Amount Fair Value Mortgage banking derivative assets Interest rate lock commitments Other assets $ 9,123 $ 133 $ 3,477 $ 25 Forward sales commitments Other assets 2,772 9 1,761 11 Mortgage banking derivative assets $ 11,895 $ 142 $ 5,238 $ 36 Mortgage banking derivative liabilities Interest rate lock commitments Other liabilities $ 268 $ 3 $ 1,615 $ 10 Forward sales commitments Other liabilities 6,619 51 5,216 47 Mortgage banking derivative liabilities $ 6,887 $ 54 $ 6,831 $ 57 Gains (losses) relating to these derivative instruments are summarized as follows for the periods presented (dollars in thousands) : Three Months Ended March 31, Location 2024 2023 Gains (losses) Interest rate lock commitments Mortgage revenue $ 267 $ 37 Forward sales commitments Mortgage revenue 9 ( 54 ) Interest rate lock commitments Other expense 5 — Forward sales commitments Other expense 51 — NOTE 12. FAIR VALUE MEASUREMENTS The fair value of an asset or liability is the price that would be received by selling that asset or paid in transferring that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820 “Fair Value Measurement” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows: • Level 1 Inputs —Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. 51 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) • Level 2 Inputs —Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means. • Level 3 Inputs —Unobservable inputs for determining the fair values of assets or liabilities that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to Busey’s assets and liabilities that are carried at fair value. In general, fair value is based upon quoted market prices, when available. If such quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable data. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect, among other things, counterparty credit quality and the company's creditworthiness as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. While management believes Busey's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. Financial Assets and Financial Liabilities Measured at Fair Value on a Recurring Basis Debt Securities Available for Sale Debt securities classified as available for sale are reported at fair value utilizing Level 2 inputs. Busey obtains fair value measurements from an independent pricing service. The independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid, and other market information. Because many fixed income securities do not trade on a daily basis, the independent pricing service applies available information to prepare evaluations, with a focus on observable market data such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing. The independent pricing service uses model processes, such as the Option Adjusted Spread model, to assess interest rate impact and develop prepayment scenarios. Models and processes take into account market conventions. For each asset class, a team of evaluators gathers information from market sources and integrates relevant credit information, perceived market movements, and sector news into the evaluated pricing applications and models. Market inputs that the independent pricing service normally seeks for evaluations of securities, listed in approximate order of priority, include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. The independent pricing service also monitors market indicators, industry, and economic events. For certain security types, additional inputs may be used or some of the market inputs may not be applicable. Evaluators may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs listed are available for use in the evaluation process for each security evaluation on a given day. Because the data utilized was observable, the securities have been classified as Level 2. 52 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Equity Securities Equity securities are reported at fair value utilizing Level 1 or Level 2 inputs. Fair value measurements of mutual funds, when held, are determined using unadjusted quoted prices in active markets for identical assets at the measurement date and are classified as Level 1. Fair value measurements of stock utilize quoted prices for identical or similar assets in markets that are not active and are classified as Level 2. Derivative Assets and Derivative Liabilities Busey’s derivative assets and derivative liabilities are reported at fair value utilizing Level 2 or Level 3 inputs. Fair values of derivative assets and liabilities are determined based on prices that are obtained from a third-party which uses observable market inputs and, with the exception of our risk participation agreements, are classified as Level 2. Due to the significance of unobservable inputs, derivative assets related to our risk participation agreements are classified as Level 3. The following tables summarize financial assets and financial liabilities measured at fair value on a recurring basis as of March 31, 2024, and December 31, 2023, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands) : As of March 31, 2024 Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Fair Value Debt securities available for sale: U.S. Treasury securities $ — $ 742 $ — $ 742 Obligations of U.S. government corporations and agencies — 5,743 — 5,743 Obligations of states and political subdivisions — 150,926 — 150,926 Asset-backed securities — 461,698 — 461,698 Commercial mortgage-backed securities — 92,563 — 92,563 Residential mortgage-backed securities — 1,021,733 — 1,021,733 Corporate debt securities — 164,667 — 164,667 Equity securities — 9,790 — 9,790 Derivative assets — 35,740 9 35,749 Derivative liabilities — 64,777 — 64,777 53 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) As of December 31, 2023 Level 1 Inputs Level 2 Inputs Level 3 Inputs Total Fair Value Debt securities available for sale: U.S. Treasury securities $ — $ 15,946 $ — $ 15,946 Obligations of U.S. government corporations and agencies — 5,832 — 5,832 Obligations of states and political subdivisions — 172,845 — 172,845 Asset-backed securities — 468,223 — 468,223 Commercial mortgage-backed securities — 103,509 — 103,509 Residential mortgage-backed securities — 1,111,312 — 1,111,312 Corporate debt securities — 209,904 — 209,904 Equity securities 448 9,364 — 9,812 Derivative assets — 29,993 15 30,008 Derivative liabilities — 54,132 — 54,132 Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). Loans Evaluated Individually Busey does not record portfolio loans at fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the collateral value is not sufficient, a specific reserve is recorded. Collateral values are estimated using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of unobservable inputs, fair values of individually evaluated collateral dependent loans have been classified as Level 3. Bank Property Held for Sale Bank property held for sale represents certain banking center office buildings which Busey has closed and consolidated with other existing banking centers. Bank property held for sale is measured at the lower of amortized cost or fair value less estimated costs to sell. Fair values were based upon discounted appraisals or real estate listing prices. Due to the significance of unobservable inputs, fair values of all bank property held for sale have been classified as Level 3.

ACQUISITION Merchants and Manufacturers Bank Corporation Effective April 1, 2024, Busey completed its previously announced acquisition of M&M, pursuant to which Busey acquired M&M and its wholly-owned subsidiary, M&M Bank, through a merger transaction. This partnership adds M&M’s Life Equity Loan ® products to Busey’s existing suite of services and expands Busey’s presence in the suburban Chicago market. 61 Table of Contents FIRST BUSEY CORPORATION NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Busey will operate M&M Bank as a separate banking subsidiary of Busey until it is merged with Busey Bank, which is expected to occur in June 2024. At the time of the bank merger, M&M Bank’s banking centers will become banking centers of Busey Bank, except for M&M’s banking center located at 990 Essington Rd., Joliet, Illinois, which is expected to be closed in connection with the bank merger. At the effective time of the Merger, each share of M&M common stock converted to the right to receive, at the election of each stockholder and subject to proration and adjustment as provided in the Merger Agreement, either (1) $ 117.74 in cash (“Cash Election”), (2) 5.7294 shares of Busey common stock (“Share Election”), or (3) mixed consideration of $ 34.55 in cash and 4.0481 shares of Busey common stock (“Mixed Election”). Most of the M&M common stockholders who submitted an election form by the election deadline made the Share Election to receive their Merger consideration solely in the form of shares of Busey common stock. As a result of the elections of M&M common stockholders, and in accordance with the proration and adjustment provisions of the Merger Agreement, the Merger consideration paid to M&M common stockholders was comprised of an aggregate of approximately 1,429,304 shares of Busey common stock and an aggregate of approximately $ 12.2 million in cash, allocated as follows for each share of M&M stock: (1) $ 117.74 in cash for the Cash Election, (2) $ 5.3966 in cash and 5.4668 shares of Busey common stock for the Share Election, and (3) $ 34.55 in cash and 4.0481 shares of Busey common stock for the Mixed Election. Pursuant to the terms of the Merger Agreement, M&M common stockholders that did not make an election or submit a properly completed election form by the election deadline of March 29, 2024, received cash consideration of $ 117.74 for each share of M&M common stock held. No fractional shares of Busey common stock were issued in the Merger. Fractional shares were paid in cash at the rate of $ 23.32 per share. This transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged was recorded at estimated fair values on April 1, 2024, the date of acquisition. Fair values will be subject to refinement for up to one year after the closing date as additional information regarding the closing date fair values becomes available. During the three months ended March 31, 2024, Busey incurred $ 0.3 million in pre-tax acquisition expenses, comprised primarily of legal expenses, related to the acquisition of M&M. 62 Table of Contents ITEM 2.

BUSINESS First Busey Corporation is a $11.9 billion financial holding company headquartered in Champaign, Illinois. Our common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.” Our three operating segments provide a full range of banking, wealth management, and payment technology solutions through our subsidiaries, Busey Bank and FirsTech, in Illinois; the St. Louis, Missouri metropolitan area; southwest Florida; and Indianapolis, Indiana. Banking Center Markets Busey Bank serves the Illinois banking market with 46 banking centers, including 21 located within central Illinois, 13 located within the suburban Chicago market, and 12 located within the St. Louis Metropolitan Statistical Area. Our Illinois markets feature several Fortune 1000 companies. Those organizations, coupled with large healthcare and higher education sectors, anchor the communities in which they are located and have provided a comparatively stable foundation for housing, employment, and small business. Busey Bank has eight banking centers in Missouri. St. Louis, Missouri has a diverse economy with major employment sectors including health care, financial services, professional and business services, and retail. We have a total of 20 banking centers within the boundaries of the St. Louis Metropolitan Statistical Area, including branches in both Illinois and Missouri. Busey Bank has three banking centers in southwest Florida, an area which has experienced strong population growth, job growth, and an expanded housing market, as well as the benefits of a tourism and winter resort economy. Busey Bank has one banking center in the Indianapolis, Indiana area, which is the most populous city of Indiana with a diverse economy, due in part to it serving as the headquarters of many large corporations. Busey's Conservative Banking Strategy Busey’s financial strength is built on a long-term conservative operating approach. The quality of our core deposit franchise is a critical value driver of our institution. Busey remains substantially core deposit 1 funded, with robust liquidity and significant market share in the communities we serve. As of March 31, 2024, our loan to deposit ratio was 76.2% and core deposits represented 96.7% of total deposits. Furthermore, we have sufficient on- and off-balance sheet liquidity to manage deposit fluctuations and the liquidity needs of our customers. Our credit performance reflects our highly diversified, conservatively underwritten loan portfolio, which has been originated predominantly to established customers with tenured relationships with Busey. Our approach to lending and our underwriting standards are designed to emphasize relationship banking rather than transactional banking. In addition, as a matter of both policy and practice, we limit concentration exposures in any particular loan segment. As a result, asset quality remains strong by both Busey’s historical and current industry trends. 1 Core deposits is a non-GAAP financial measure. For a reconciliation of non-GAAP measures to the most directly comparable GAAP financial measures, see “Item 2. Management’s Discussion and Analysis—Non-GAAP Financial Information” included in this Quarterly Report. 64 Table of Contents Busey’s conservative banking strategy is reflected in the strength of our capital base. We strive to consistently maintain capital ratios well in excess of thresholds required to be designated as well capitalized by applicable regulatory guidelines, thereby ensuring financial strength and flexibility across economic and operating cycles. At March 31, 2024, our leverage ratio of Tier 1 capital to average assets was 10.5%, our common equity Tier 1 capital to risk weighted assets ratio was 13.4%, and our total capital to risk weighted assets ratio was 17.9%. Acquisition Effective April 1, 2024, Busey completed its previously announced acquisition of M&M, pursuant to which Busey acquired M&M and its wholly-owned subsidiary, M&M Bank, through a merger transaction. This partnership adds M&M’s Life Equity Loan ® products to Busey’s existing suite of services and expands Busey’s presence in the suburban Chicago market. Busey will operate M&M Bank as a separate banking subsidiary of Busey until it is merged with Busey Bank, which is expected to occur in June 2024. At the time of the bank merger, M&M Bank’s banking centers will become banking centers of Busey Bank, except for M&M’s banking center located at 990 Essington Rd., Joliet, Illinois, which is expected to be closed in connection with the bank merger. For additional information, see “ Note 16. Acquisition .” Busey executed a two-part balance sheet repositioning strategy During the first quarter of 2024, Busey sold the mortgage servicing rights on approximately $923.5 million of one- to four-family mortgage loans for an estimated pre-tax gain of $7.5 million, which enabled us to sell available-for-sale investment securities with a book value of approximately $108.2 million for a pre-tax loss of $6.8 million with no resulting impact to tangible capital. At the time of the sale, the securities sold yielded a weighted average rate of 1.98% and had a weighted-average life of 2.3 years. Proceeds from the repositioning were deposited into an interest-bearing account at the Federal Reserve yielding 5.40%. Busey anticipates reinvesting the proceeds into higher yielding organic growth opportunities over time. The increased net interest spread as a result of the two-part repositioning is expected to increase net interest income by approximately $3.3 million on an annualized basis and improve the net interest margin run rate by 3 basis points. In addition, execution of these transactions further bolsters Busey’s liquidity position and balance sheet flexibility, while also strengthening its capital position. In combination, the gain generated from the sale of mortgage servicing rights and the loss generated from the sale of securities had an immediate positive impact on consolidated stockholders’ equity and book value per share. Risk-based regulatory capital ratios increased modestly as a result of the repositioning proceeds rotating into lower risk-weighted assets. Busey expects the above transactions to be accretive to capital and earnings per share in future periods. 65 Table of Contents RESULTS OF OPERATIONS — THREE MONTHS ENDED MARCH 31, 2024 Net Income Results of our operations are presented below, segregated by operating segment (dollars in thousands) : Three Months Ended March 31, 2024 2023 Net income by operating segment Banking $ 26,492 $ 36,835 Wealth Management 4,998 4,858 FirsTech 86 (38) Other (5,351) (4,869) Net income $ 26,225 $ 36,786 Operating Performance Metrics Operating performance metrics presented in the table below have been derived from information used by management to monitor and manage Busey’s financial performance (dollars in thousands, except per share amounts) : Three Months Ended March 31, 2024 2023 Reported: Net income $ 26,225 $ 36,786 Adjusted: Net income 1 $ 26,531 $ 36,786 Reported: Diluted earnings per common share $ 0.46 $ 0.65 Adjusted: Diluted earnings per common share 1 $ 0.47 $ 0.65 Reported: Return on average assets 2 0.88 % 1.22 % Adjusted: Return on average assets 1, 2 0.89 % 1.22 % Reported: Return on average tangible common equity 1, 2 11.43 % 18.48 % Adjusted: Return on average tangible common equity 1, 2 11.56 % 18.48 % Reported: Pre-provision net revenue 1 $ 46,373 $ 47,918 Adjusted: Pre-provision net revenue 1 $ 38,638 $ 49,504 Reported: Pre-provision net revenue to average assets 1, 2 1.55 % 1.58 % Adjusted: Pre-provision net revenue to average assets 1, 2 1.29 % 1.64 % ___________________________________________ 1.

See “Item 2. Management’s Discussion and Analysis—Non-GAAP Financial Information.” Net Interest Income Net interest income is the difference between interest income and fees earned on earning assets and interest expense incurred on interest-bearing liabilities. Interest rate levels and volume fluctuations within earning assets and interest-bearing liabilities impact net interest income. Net interest margin is tax-equivalent net interest income as a percent of average earning assets. Certain assets with tax favorable treatment are evaluated on a tax-equivalent basis, assuming a federal income tax rate of 21.0%. Tax favorable assets generally have lower contractual pre-tax yields than fully taxable assets. A tax-equivalent analysis is performed by adding the tax savings to the earnings on tax favorable assets. After factoring in the tax favorable effects of these assets, the yields may be more appropriately evaluated against alternative earning assets. In addition to yield, various other risks are factored into the evaluation process.

Net interest income expressed as a percentage of average earning assets, stated on a tax-equivalent basis. The FOMC raised rates by a total of 525 basis points since the onset of the current FOMC tightening cycle that began in the first quarter of 2022, with no further increases during the first quarter of 2024. Rising rates initially have a positive impact on net interest margin, as assets, in particular commercial loans, reprice more quickly and to a greater extent than liabilities. As deposit and funding costs increase in response to the tightening rate cycle, some of the net interest margin expansion is reversed. As lower yielding securities and loans have continued to mature or renew at higher current market rates, expansion in asset yields has outpaced any remaining lagged pressure on funding costs. Our deposit cost of funds peaked in the beginning of the first quarter of 2024, and we have been able to reduce interest expense by offering lower CD specials as well as applying rate management on higher priced non-maturity deposit products. We have also begun to benefit from recent actions taken to proactively bolster our net interest margin, including completion of targeted balance sheet repositionings in both the fourth quarter of 2023 and the first quarter of 2024, the reversal of the wealth management sweep accounts, and the pay off of the remaining balance on our Term Loan. 69 Table of Contents Net interest spread represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, and is presented in the table below for the periods indicated: Three Months Ended March 31, 2024 2023 Net interest spread 1 2.04 % 2.71 % ___________________________________________ 1.

Total noninterest income represented 31.6% of total revenue 2 for the three months ended March 31, 2024, compared to 27.1% for the comparable period in 2023. Combined, revenues from wealth management fees and payment technology solutions represented 60.7% of Busey’s noninterest income for the three months ended March 31, 2024, providing a complement to spread-based revenue from traditional banking activities. On a combined basis, revenue from these two critical operating areas was $21.3 million for the three months ended March 31, 2024, a 5.7% increase from the comparable period in 2023. Wealth management fees were $15.5 million for the three months ended March 31, 2024, a 5.1% increase from the comparable period in 2023. Busey’s Wealth Management division ended the first quarter of 2024 with $12.8 billion in assets under care, an increase of 13.9% from the comparable period in 2023. Our portfolio management team continues to focus on long-term returns and managing risk in the face of volatile markets. Payment technology solutions revenue relates to our payment processing company, FirsTech. Payment technology solutions revenue was $5.7 million for the three months ended March 31, 2024, a 7.4% increase from the comparable period in 2023. 2 Total revenue consists of net interest income plus noninterest income. 71 Table of Contents Fees for customer services were $7.1 million for the three months ended March 31, 2024, a 3.5% increase from the comparable period in 2023. Mortgage revenue was $0.7 million for the three months ended March 31, 2024, a 159.0% increase from the comparable period in 2023, primarily based on sold-loan mortgage volume. General economic conditions and interest rate volatility may impact future fee income. The sale of the mortgage servicing rights completed during the first quarter of 2024 is expected to reduce mortgage revenue by an average of $0.2 million per quarter for the remainder of the year. Income on bank owned life insurance was $1.4 million for the three months ended March 31, 2024, a 14.1% decrease from the comparable period in 2023, as a result of a $0.3 million decrease in earnings on death proceeds and a $0.1 million increase in the cash surrender value of the insurance policies. A realized gain on the sale of mortgage servicing rights was recognized in connection with our strategic two-part balance sheet repositioning completed during the first quarter of 2024. For more information, see “ Management’s Discussion and Analysis of Financial Condition and Results of Operations — Busey executed a two-part balance sheet repositioning strategy .” Other income was $3.4 million for the three months ended March 31, 2024, a 4.5% decrease from the comparable period in 2023. Fluctuations were primarily attributable to increased income recognized on venture capital investments and higher gains on commercial loan sales, offset by lower income on swap origination fees and reductions in gains on fixed asset disposals. 72 Table of Contents Noninterest Expense Changes in noninterest expense are summarized as follows for the periods presented (dollars in thousands) : Three Months Ended March 31, 2024 2023 Change % Change Noninterest expense Salaries, wages, and employee benefits $ 42,090 $ 40,331 $ 1,759 4.4 % Data processing 6,550 5,640 910 16.1 % Premises expenses: Net occupancy expense of premises 4,720 4,762 (42) (0.9) % Furniture and equipment expenses 1,813 1,746 67 3.8 % Combined, net occupancy expense of premises and furniture and equipment expenses 6,533 6,508 25 0.4 % Professional fees 2,253 2,058 195 9.5 % Amortization of intangible assets 2,409 2,729 (320) (11.7) % Interchange expense 1,611 1,853 (242) (13.1) % FDIC insurance 1,400 1,502 (102) (6.8) % Other expense 7,923 9,782 (1,859) (19.0) % Total noninterest expense $ 70,769 $ 70,403 $ 366 0.5 % Income taxes $ 8,735 $ 9,563 $ (828) (8.7) % Effective income tax rate 25.0 % 20.6 % 440 bps Efficiency ratio 1 58.1 % 56.9 % 120 bps Adjusted efficiency ratio 1 61.7 % 56.9 % 480 bps Full-time equivalent associates as of period-end 1,464 1,473 (9) (0.6) % ___________________________________________ 1.

Total noninterest expense was $70.8 million for the three months ended March 31, 2024, representing a modest 0.5% increase from the comparable period in 2023. We have effectively managed our noninterest expense during a time of decades-high inflation, and have been purposeful in our efforts to rationalize our expense base given our economic outlook and our view on the future of banking. Salaries, wages, and employee benefits were $42.1 million for the three months ended March 31, 2024, a 4.4% increase from the comparable period in 2023. Our total associate base consisted of 1,464 full-time equivalents as of March 31, 2024, compared to 1,473 full-time equivalents at March 31, 2023. Current trends continue to reflect a competitive labor market, maintaining pressure on costs related to attracting and maintaining our skilled workforce. Data processing expense was $6.6 million for the three months ended March 31, 2024, a 16.1% increase from the comparable period in 2023. Increases were primarily attributable to Company-wide investments in technology enhancements, as well as inflation-driven price increases. 73 Table of Contents Combined, net occupancy expense of premises and furniture and equipment expense totaled $6.5 million for the three months ended March 31, 2024, an 0.4% increase from the comparable period in 2023. Primary cost drivers in these expense categories include lease costs, repairs and maintenance, depreciation expense, real estate taxes, and utilities. Professional fees were $2.3 million for the three months ended March 31, 2024, a 9.5% increase from the comparable period in 2023. The three months ended March 31, 2024, includes $0.1 of non-operating costs related to the M&M acquisition. Amortization of intangible assets was $2.4 million for the three months ended March 31, 2024, an 11.7% decrease from the comparable period for 2023, due to the use of an accelerated amortization methodology. Interchange expense was $1.6 million for the three months ended March 31, 2024, a 13.1% decrease from the comparable period in 2023. Fluctuations in interchange expense relate to payment and volume activity at FirsTech. FDIC insurance expense was $1.4 million for the three months ended March 31, 2024, a 6.8% decrease from the comparable period in 2023. Other expense was $7.9 million for the three months ended March 31, 2024, a 19.0% decrease from the comparable period in 2023. In connection with Busey’s adoption of ASU 2023-02 on January 1, 2024, Busey began recording amortization of New Markets Tax Credits as income tax expense instead of other expense, which resulted in a $2.2 million decrease in other expense during the first quarter of 2024, compared to the first quarter of 2023. Further changes in other expense are attributable to multiple items, including the provision for unfunded commitments, sales of other real estate owned, marketing, and business development expenses. Efficiency Ratio The efficiency ratio 3 , which is a measure commonly used by management and the banking industry, measures the amount of expense incurred to generate a dollar of revenue. Our efficiency ratio was 58.1% for the three months ended March 31, 2024, compared to 56.9% for the three months ended March 31, 2023. Our adjusted efficiency ratio 3 was 61.7% for the three months ended March 31, 2024, compared to 56.9% for three months ended March 31, 2023. Taxes The effective income tax rate of 25.0% for the three months ended March 31, 2024, was lower than the combined federal and state statutory rate of approximately 28.0% due to tax exempt interest income, such as municipal bond interest and bank owned life insurance income. The effective tax rate was higher in the first quarter of 2024 compared to previous quarters due to the adoption of ASU 2023-02 in January 2024. We continue to monitor evolving federal and state tax legislation and its potential impact on operations on an ongoing basis.

Busey maintains lending policies and procedures designed to focus lending efforts on the types, locations, and duration of loans most appropriate for its business model and markets. While not specifically limited, we attempt to focus our lending on short to intermediate-term (0-10 years) loans in geographic areas within 125 miles of our lending offices. Loans originated outside of these areas are generally to existing customers of Busey Bank. We attempt to utilize government-assisted lending programs, such as the SBA and U.S. Department of Agriculture lending programs, when prudent. Generally, loans are collateralized by assets, primarily real estate, and guaranteed by individuals. Loans are expected to be repaid primarily from cash flows of the borrowers or from proceeds from the sale of selected assets of the borrowers. Management reviews and approves Busey Bank’s lending policies and procedures on a regular basis. Management routinely (at least quarterly) reviews the ACL in conjunction with reports related to loan production, loan quality, concentrations of credit, loan delinquencies, non-performing loans, and potential problem loans. Our underwriting standards are designed to encourage relationship banking rather than transactional banking. Relationship banking implies a primary banking relationship with the borrower that includes, at a minimum, an active deposit banking relationship in addition to the lending relationship. Significant underwriting factors, in addition to location, duration, a sound and profitable cash flow basis, and the borrower’s character, include the quality of the borrower’s financial history, the liquidity of the underlying collateral, and the reliability of the valuation of the underlying collateral. 75 Table of Contents At no time is a borrower’s total borrowing relationship permitted to exceed Busey Bank’s regulatory lending limit. We generally limit such relationships to amounts substantially less than the regulatory limit. Loans to related parties, including executive officers and directors of First Busey Corporation and its subsidiaries, are reviewed for compliance with regulatory guidelines. Busey maintains an independent loan review department that reviews loans for compliance with our loan policy on a periodic basis. In addition, the loan review department reviews risk assessments made by our credit department, lenders, and loan committees. Results of these reviews are presented to management and the audit committee at least quarterly. Busey Bank’s lending activities can be summarized into two primary categories: commercial and retail. Lending is further classified into five primary areas: commercial loans, commercial real estate loans, real estate construction loans, retail real estate loans, and retail other loans. A description of each of the five primary areas can be found in “ Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations —Portfolio Loans ” of Busey’s 2023 Annual Report .

This posture will continue to impact loan growth, which we expect to remain modest over the next several quarters. 76 Table of Contents Concentration of credit risk As a matter of policy and practice, we limit the level of concentration exposure in any particular loan segment with the goal of maintaining a well-diversified loan portfolio.

The methodology adopted influences, and is influenced by, Busey Bank’s overall credit risk management processes. The ACL is recorded in accordance with GAAP to provide an adequate reserve for expected credit losses that is reflective of management’s best estimate of what is expected to be collected. Estimates of credit losses are based on a careful consideration of all significant factors affecting collectability as of the evaluation date. The ACL is established through the provision for credit loss expense charged to income. Provision expenses were recorded as follows for each of the periods indicated (dollars in thousands) : Three Months Ended March 31, 2024 2023 Provision for credit losses $ 5,038 $ 953 The ACL and the ratio of ACL to portfolio loan balances is presented below by loan category and class, as of each of the dates indicated (dollars in thousands) : As of March 31, 2024 As of December 31, 2023 Portfolio Loans ACL Ratio of ACL to Portfolio Loans Portfolio Loans ACL Ratio of ACL to Portfolio Loans Commercial C&I and other commercial $ 1,828,711 $ 26,207 1.43 % $ 1,835,994 $ 21,256 1.16 % Commercial real estate 3,331,670 33,505 1.01 % 3,337,337 35,465 1.06 % Real estate construction 445,860 4,713 1.06 % 461,717 5,163 1.12 % Total commercial 5,606,241 64,425 1.15 % 5,635,048 61,884 1.10 % Retail Retail real estate 1,708,663 24,281 1.42 % 1,720,455 26,298 1.53 % Retail other 273,173 2,856 1.05 % 295,531 3,558 1.20 % Total retail 1,981,836 27,137 1.37 % 2,015,986 29,856 1.48 % Total $ 7,588,077 $ 91,562 1.21 % $ 7,651,034 $ 91,740 1.20 % As of March 31, 2024, management believed the level of the ACL to be appropriate based upon the information available. However, additional losses may be identified in our loan portfolio as new information is obtained. The ongoing impacts of CECL will be dependent upon changes in economic conditions and forecasts, originated and acquired loan portfolio composition, prepayment speeds, credit performance trends, portfolio duration, and other factors. Non-Performing Loans and Non-Performing Assets Loans are considered past due if the required principal or interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory guidelines. Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured. Typically, loans are secured by collateral. When a loan is classified as non-accrual and determined to be collateral dependent, it is appropriately reserved or charged down through the ACL to the fair value of our interest in the underlying collateral less estimated costs to sell. Our loan portfolio is collateralized primarily by real estate. 79 Table of Contents The following table sets forth information concerning non-performing loans and performing restructured loans, as of each of the dates indicated (dollars in thousands) : As of March 31, 2024 December 31, 2023 Change % Change Portfolio loans $ 7,588,077 $ 7,651,034 $ (62,957) (0.8) % Loans 30 – 89 days past due 7,441 5,779 1,662 28.8 % Total assets 11,887,458 12,283,415 (395,957) (3.2) % Non-performing assets Non-performing loans: Non-accrual loans $ 17,465 $ 7,441 $ 10,024 134.7 % Loans 90+ days past due and still accruing 88 375 (287) (76.5) % Total non-performing loans 17,553 7,816 9,737 124.6 % OREO and other repossessed assets 65 125 (60) (48.0) % Total non-performing assets 17,618 7,941 9,677 121.9 % Substandard (excludes 90+ days past due) 87,830 64,347 23,483 36.5 % Classified assets $ 105,448 $ 72,288 $ 33,160 45.9 % ACL $ 91,562 $ 91,740 $ (178) (0.2) % Bank Tier 1 Capital 1,365,033 1,362,962 2,071 0.2 % Ratios ACL to portfolio loans 1.21 % 1.20 % 1 bps ACL to non-accrual loans 524.26 % 1,232.90 % NM ACL to non-performing loans 521.63 % 1,173.75 % NM ACL to non-performing assets 519.71 % 1,155.27 % NM Non-accrual loans to portfolio loans 0.23 % 0.10 % 13 bps Non-performing loans to portfolio loans 0.23 % 0.10 % 13 bps Non-performing assets to total assets 0.15 % 0.06 % 9 bps Non-performing assets to portfolio loans and OREO and other repossessed assets 0.23 % 0.10 % 13 bps Classified assets to Bank Tier 1 Capital and ACL 7.24 % 4.97 % 227 bps Asset quality remains strong by both Busey’s historical and current industry trends, and our operating mandate and focus have been on emphasizing credit quality over asset growth. Non-performing loan balances increased to $17.6 million as of March 31, 2024, compared to $7.8 million as of December 31, 2023. Non-performing loans represented 0.23% of portfolio loans as of March 31, 2024, compared to 0.10% as of December 31, 2023. Our allowance for credit losses provided 521.63% coverage of non-performing loans at March 31, 2024, compared to 1,173.75% at December 31, 2023. The increase in non-performing loans during the first quarter of 2024 can be substantially attributed to a single commercial credit relationship. 80 Table of Contents Non-performing assets, which includes non-performing loans, OREO, and other repossessed assets, increased to $17.6 million as of March 31, 2024, compared to $7.9 million as of December 31, 2023. Non-performing assets represented 0.15% of total assets as of March 31, 2024, compared to 0.06% as of December 31, 2023. Our allowance for credit losses provided 519.71% coverage of our non-performing assets at March 31, 2024, compared to 1,155.27% at December 31, 2023. Classified assets, which includes non-performing assets and substandard loans, increased to $105.4 million as of March 31, 2024, compared to $72.3 million as of December 31, 2023. Classified assets represented 7.24% of Busey Bank’s Tier 1 capital and ACL at March 31, 2024, compared to 4.97% at December 31, 2023. Net charge-offs totaled $5.2 million for the three months ended March 31, 2024, compared to $0.8 million for the three months ended March 31, 2023. The increase in net charge-offs during the first quarter of 2024 was attributable to the single commercial credit relationship mentioned above. Asset quality metrics remain dependent upon market-specific economic conditions, and specific measures may fluctuate from period to period. If economic conditions were to deteriorate, we would expect the credit quality of our loan portfolio to decline and loan defaults to increase. Potential Problem Loans Potential problem loans are loans classified as substandard which are not individually evaluated, non-accrual, or 90+ days past due, but where current information indicates that the borrower may not be able to comply with loan repayment terms. Management assesses the potential for loss on such loans and considers the effect of any potential loss in determining its provision for expected credit losses. Potential problem loans increased to $87.8 million as of March 31, 2024, compared to $64.3 million as of December 31, 2023. Management continues to monitor these loans and anticipates that restructurings, guarantees, additional collateral, or other planned actions will result in full repayment of the debts. As of March 31, 2024, management identified no other loans that represent or result from trends or uncertainties which would be expected to materially impact future operating results, liquidity, or capital resources. Deposits Total deposits decreased by 3.2% to $9.96 billion as of March 31, 2024, compared to $10.29 billion as of December 31, 2023. During the first quarter of 2024, we moved $129.7 million of wealth management client funds that had previously been swept into interest-bearing money market accounts at Busey Bank back to money market investments managed by the Wealth Management division. Remaining decreases in total deposits were attributable to normal seasonal flows in our public fund accounts. The quality of our core deposit 4 franchise coupled with cash flows from our securities portfolio allows us to fund loan growth while limiting our reliance on higher cost wholesale funding alternatives. We focus on deepening our relationships with customers to maintain and protect our strong core deposit franchise. As of March 31, 2024, our average customer tenure was 16.6 years for retail customers and 12.4 years for commercial customers. Core deposits include non-brokered transaction accounts, money market and savings deposit accounts, and time deposits of $250,000 or less. Core deposits represented 96.7% of total deposits as of March 31, 2024, compared to 96.2% as of December 31, 2023. Our estimated amount of uninsured deposits was $3.63 billion as of March 31, 2024, compared to $3.81 billion as of December 31, 2023. 4 Core deposits is a non-GAAP financial measure. For a reconciliation of non-GAAP measures to the most directly comparable GAAP financial measures, see “Item 2. Management’s Discussion and Analysis—Non-GAAP Financial Information” included in this Quarterly Report. 81 Table of Contents Liquidity Liquidity management is the process by which we ensure that adequate liquid funds are available to meet the present and future cash flow obligations arising in the daily operations of our business. These financial obligations consist of needs for funds to meet commitments to borrowers for extensions of credit, fund capital expenditures, honor withdrawals by customers, pay dividends to stockholders, and pay operating expenses. Our most liquid assets are cash and due from banks, interest-bearing bank deposits, and federal funds sold. Balances of these assets are dependent on our operating, investing, lending, and financing activities during any given period. Average liquid assets are summarized in the table below (dollars in thousands) : Three Months Ended March 31, 2024 2023 Average liquid assets Cash and due from banks $ 105,583 $ 115,145 Interest-bearing bank deposits 488,610 108,051 Total average liquid assets $ 594,193 $ 223,196 Average liquid assets as a percent of average total assets 4.9 % 1.8 % Cash and unencumbered securities on our Consolidated Balance Sheets (Unaudited) are summarized as follows (dollars in thousands) : As of March 31, 2024 December 31, 2023 Cash and unencumbered securities Total cash and cash equivalents $ 591,071 $ 719,581 Debt securities available for sale 1,898,072 2,087,571 Debt securities available for sale pledged as collateral (596,692) (649,769) Cash and unencumbered securities $ 1,892,451 $ 2,157,383 Busey’s primary sources of funds consist of deposits, investment maturities and sales, loan principal repayments, and capital funds. Additional liquidity is provided by the ability to borrow from the FHLB, the Federal Reserve, and our revolving credit facility, as summarized in the table below (dollars in thousands) : As of March 31, 2024 December 31, 2023 Additional available borrowing capacity FHLB $ 2,034,762 $ 1,898,737 Federal Reserve Bank 608,694 598,878 Federal funds purchased 477,500 482,500 Revolving credit facility 40,000 40,000 Additional borrowing capacity $ 3,160,956 $ 3,020,115 Further, the company could utilize brokered deposits as additional sources of liquidity, as needed. 82 Table of Contents As of March 31, 2024, management believed that adequate liquidity existed to meet all projected cash flow obligations. We seek to achieve a satisfactory degree of liquidity by actively managing both assets and liabilities. Asset management guides the proportion of liquid assets to total assets, while liability management monitors future funding requirements and prices liabilities accordingly. Off-Balance-Sheet Arrangements Busey Bank routinely enters into commitments to extend credit and standby letters of credit in the normal course of business to meet the financing needs of its customers. The balance of commitments to extend credit represents future cash requirements and some of these commitments may expire without being drawn upon. The following table summarizes our outstanding commitments and reserves for unfunded commitments (dollars in thousands) : As of March 31, 2024 December 31, 2023 Outstanding loan commitments and standby letters of credit $ 2,165,588 $ 2,176,496 Reserve for unfunded commitments 6,384 7,062 The following table summarizes our provision for unfunded commitments expenses (releases) for the periods presented (dollars in thousands) : Three Months Ended March 31, 2024 2023 Provision for unfunded commitments expense (release) $ (678) $ (635) We anticipate we will have sufficient funds available to meet current loan commitments, including loan applications received and in process prior to the issuance of firm commitments. Capital Resources Our capital ratios are in excess of those required to be considered “well-capitalized” pursuant to applicable regulatory guidelines. The Federal Reserve Board uses capital adequacy guidelines in its examination and regulation of bank holding companies and their subsidiary banks. Risk-based capital ratios are established by allocating assets and certain off-balance-sheet commitments into risk-weighted categories. These balances are then multiplied by the factor appropriate for that risk-weighted category. In order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments, banking institutions must maintain capital in excess of regulatory minimum capital requirements. The table below presents minimum capital ratios that include the capital conservation buffer in comparison to the capital ratios for First Busey and Busey Bank as of March 31, 2024: Minimum Capital Requirements with Capital Buffer As of March 31, 2024 First Busey Busey Bank Common Equity Tier 1 Capital to Risk Weighted Assets 7.00 % 13.45 % 15.79 % Tier 1 Capital to Risk Weighted Assets 8.50 % 14.30 % 15.79 % Total Capital to Risk Weighted Assets 10.50 % 17.95 % 16.84 % Leverage Ratio of Tier 1 Capital to Average Assets 6.50 % 10.46 % 11.53 % For further discussion of capital resources and requirements, see “Note 7: Regulatory Capital.” 83 Table of Contents NON-GAAP FINANCIAL INFORMATION This Quarterly Report contains certain financial information determined by methods other than in accordance with GAAP. Management uses these non-GAAP financial measures and non-GAAP ratios, together with the related GAAP financial measures, in analysis of Busey’s performance and in making business decisions, as well as for comparison to Busey’s peers. We believe 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 our performance over time. Non-GAAP disclosures have inherent limitations and are not audited.

Forward-looking statements, which may be based upon beliefs, expectations, and assumptions of Busey’s 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 Quarterly Report, including forward-looking statements, speak only as of the date they are made, and Busey undertakes no 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 to control or predict, could cause actual results to differ materially from those in any forward-looking statements. These factors include, among others, the following: (1) the strength of the local, state, national, and international economy (including effects of inflationary pressures and supply chain constraints); (2) the economic impact of any future terrorist threats or attacks, widespread disease or pandemics, 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); (3) changes in state and federal laws, regulations, and governmental policies concerning Busey's general business (including changes in response to the failures of other banks or as a result of the upcoming 2024 presidential election); (4) changes in accounting policies and practices; (5) changes in interest rates and prepayment rates of Busey’s assets (including the impact of the significant rate increases by the Federal Reserve since 2022) (6) 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; (7) changes in technology and the ability to develop and maintain secure and reliable electronic systems; (8) the loss of key executives or associates; (9) changes in consumer spending; (10) unexpected results of acquisitions (including the acquisition of M&M); (11) unexpected outcomes of existing or new litigation, investigations, or inquiries involving Busey (including with respect to Busey’s Illinois franchise taxes); (12) fluctuations in the value of securities held in Busey’s securities portfolio; (13) concentrations within Busey’s loan portfolio, large loans to certain borrowers, and large deposits from certain clients; (14) the concentration of large deposits from certain clients who have balances above current FDIC insurance limits and may withdraw deposits to diversify their exposure; (15) the level of non-performing assets on Busey’s balance sheets; (16) interruptions involving information technology and communications systems or third-party servicers; (17) breaches or failures of information security controls or cybersecurity-related incidents; and (18) 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. Additional information concerning Busey and its business, including additional factors that could materially affect Busey’s financial results, is included in Busey’s filings with the Securities and Exchange Commission. CRITICAL ACCOUNTING ESTIMATES Busey has established various accounting policies that govern the application of GAAP in the preparation of its unaudited consolidated financial statements. Significant accounting policies are described in “ Note 1. Significant Accounting Policies ” of Busey’s 2023 Annual Report . Critical accounting estimates are those that are critical to the portrayal and understanding of Busey’s financial condition and results of operations and require management to make assumptions that are difficult, subjective, or complex. These estimates involve judgments, assumptions, and uncertainties that are susceptible to change. In the event that different assumptions or conditions were to prevail, and depending on the severity of such changes, the possibility of a materially different financial condition or materially different results of operations is a reasonable likelihood. Further, changes in accounting standards could impact our critical accounting estimates. Management has reviewed these critical accounting estimates and related disclosures with our Audit Committee. The following accounting policies could be deemed critical: 92 Table of Contents Fair Value of Debt Securities Available for Sale Fair values of debt securities available for sale are measurements from an independent pricing service and are based on observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other things. Different fair value estimates could result from the use of different judgments and estimates to determine the fair values of securities. Realized securities gains or losses are reported in the Consolidated Statements of Income (Unaudited). The cost of securities sold is based on the specific identification method. A debt security available for sale is impaired if the fair value of the security declines below its amortized cost basis. To determine the appropriate accounting, we must first determine if we intend to sell the security or if it is more likely than not that we will be required to sell the security before the fair value increases to at least the amortized cost basis. If either of those selling events is expected, we will write down the amortized cost basis of the security to its fair value. This is achieved by writing off any previously recorded allowance related to the debt security, if applicable, and recognizing any incremental impairment through earnings. If we do not intend to sell the security, nor believe it more likely than not that we will be required to sell the security before the fair value recovers to the amortized cost basis, we must determine whether any of the decline in fair value has resulted from a credit loss, or if it is entirely the result of noncredit factors. We consider the following factors in assessing whether the decline is due to a credit loss: • Extent to which the fair value is less than the amortized cost basis; • adverse conditions specifically related to the security, an industry, or a geographic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset-backed debt security, in the financial condition of the underlying loan obligors); • payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future; • failure of the issuer of the security to make scheduled interest or principal payments; and • any changes to the rating of the security by a rating agency. Impairment related to a credit loss must be measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. Impairment is recognized by establishing an allowance for the debt security through the provision for credit losses. Impairment related to noncredit factors is recognized in AOCI, net of applicable taxes. Fair Value of Assets Acquired and Liabilities Assumed in Business Combinations Business combinations are accounted for using the acquisition method of accounting. Under the acquisition method of accounting, assets acquired and liabilities assumed are recorded at their estimated fair value on the date of acquisition. Fair values are determined based on the definition of “fair value” defined in ASC Topic 820 “Fair Value Measurement” as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.” 93 Table of Contents The fair value of a loan portfolio acquired in a business combination generally requires greater levels of management estimates and judgment than other assets acquired or liabilities assumed. Acquired loans are within the scope of ASC Topic 326 “Financial Instruments-Credit Losses.” However, the offset to record the allowance on acquired loans at the date of acquisition depends on whether or not the loan is classified as PCD. The allowance for PCD loans is recorded through a gross-up effect, while the allowance for acquired non-PCD loans is recorded through provision expense, consistent with originated loans. Thus, the determination of which loans are PCD and non-PCD can have a significant effect on the accounting for these loans. Goodwill Goodwill represents the excess of purchase price over the fair value of net assets acquired using the acquisition method of accounting. Determining the fair value often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Goodwill is not amortized. Instead, we assess the potential for impairment on an annual basis or more frequently if events and circumstances indicate that goodwill might be impaired. Income Taxes Busey estimates income tax expense based on amounts expected to be owed to federal and state tax jurisdictions. Estimated income tax expense is reported in the Consolidated Statements of Income (Unaudited). Accrued and deferred taxes, as reported in other assets or other liabilities in the Consolidated Balance Sheets (Unaudited), represent the net estimated amount due to, or to be received from, taxing jurisdictions, either currently or in the future. Management judgment is involved in estimating accrued and deferred taxes, as it may be necessary to evaluate the risks and merits of the tax treatment of transactions, filing positions, and taxable income calculations after considering tax-related statutes, regulations, and other relevant factors. Because of the complexity of tax laws and interpretations, interpretation is subject to judgment. Allowance for Credit Losses Busey calculates the ACL at each reporting date. We recognize an allowance for the lifetime expected credit losses for the amount we do not expect to collect. Measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported book value. The calculation also contemplates that Busey may not be able to make or obtain such forecasts for the entire life of the financial assets and requires a reversion to historical credit loss information. In determining the ACL, management relies predominantly on a disciplined credit review and approval process that extends to the full range of Busey’s credit exposure. The ACL must be determined on a collective (pool) basis when similar risk characteristics exist. On a case-by-case basis, we may conclude that a loan should be evaluated on an individual basis based on disparate risk characteristics. Loans deemed uncollectible are charged against and reduce the ACL. A provision for credit losses is charged to current expense and acts to replenish the ACL in order to maintain the ACL at a level that management deems adequate. Determining the ACL involves significant judgments and assumptions by management. Because of the nature of the judgments and assumptions made by management, actual results may differ from these judgments and assumptions. ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK Market risk is the risk of changes in asset values due to movements in underlying market rates and prices. Interest rate risk is a type of market risk to earnings and capital arising from movements in interest rates. Interest rate risk is the most significant market risk affecting Busey as other types of market risk, such as foreign currency exchange rate risk and commodity price risk, have minimal impact or do not arise in the normal course of Busey’s business activities. 94 Table of Contents Busey has an asset-liability committee, whose policy is to meet at least quarterly, to review current market conditions and to structure the Consolidated Balance Sheets (Unaudited) to optimize stability in net interest income in consideration of projected future changes in interest rates. As interest rate changes do not impact all categories of assets and liabilities equally or simultaneously, the asset-liability committee primarily relies on balance sheet and income simulation analysis to determine the potential impact of changes in market interest rates on net interest income. In these standard simulation models, the balance sheet is projected over a one-year and a two-year time horizon and net interest income is calculated under current market rates and assuming permanent instantaneous shifts of +/-100, +/-200, +/-300, and +/-400 basis points. The model assumes immediate and sustained shifts in the federal funds rate and other market rate indices and corresponding shifts in other non-market rate indices based on their historical changes relative to changes in the federal funds rate and other market indices. Assets and liabilities are assumed to remain constant as of the measurement date; variable-rate assets and liabilities are repriced based on repricing frequency; and prepayment speeds on loans are projected for both declining and rising rate environments. Busey’s interest rate risk resulting from immediate and sustained changes in interest rates, expressed as a change in net interest income as a percentage of the net interest income calculated in the constant base model, was as follows: Year-One: Basis Point Changes Year-Two: Basis Point Changes March 31, 2024 December 31, 2023 March 31, 2024 December 31, 2023 +400 8.57 % 7.38 % 9.20 % 8.55 % +300 6.38 % 5.49 % 6.81 % 6.34 % +200 4.22 % 3.64 % 4.49 % 4.20 % +100 2.10 % 1.81 % 2.24 % 2.10 % - 100 (1.90) % (1.91) % (2.89) % (2.98) % -200 (3.85) % (3.86) % (5.94) % (6.12) % -300 (5.69) % (5.60) % (9.06) % (9.17) % -400 (7.21) % (6.91) % (12.06) % (11.36) % Interest rate risk is monitored and managed within approved policy limits and any temporary exceptions to policy in periods of rapid rate movement are approved and documented. The calculation of potential effects of hypothetical interest rate changes is based on numerous assumptions and should not be relied upon as indicative of actual results. Actual results would likely differ from simulated results due to the timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies.
