**FIRST BUSEY CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

**NOTE 1. SIGNIFICANT ACCOUNTING POLICIES**

***Nature of Operations***

First Busey Corporation, a Nevada corporation organized in 1980, is an $18.19 billion financial holding company headquartered in Leawood, Kansas. Busey's common stock is traded on The Nasdaq Global Select Market under the symbol "BUSE" and Busey's depositary shares, each representing a 1/40th interest in a share of Busey Series B Preferred Stock, are traded under the symbol "BUSEP."

Busey operates and reports its business in three segments: Banking, Wealth Management, and FirsTech.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The *Banking* operating segment provides a full range of banking services to individual and corporate customers through its banking center network in Arizona, Colorado, Florida, Illinois, Indiana, Kansas, Missouri, New Mexico, Oklahoma, and Texas.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• 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 Busey's operating segments, see *"<u>[Note 16. Operating Segments and Related Information](#id43ca44fb26f43c483ff809287c9b6a0_142)</u>."* 

Busey conducts its Banking and Wealth Management services through Busey Bank, and provides payment technology solutions through Busey Bank's wholly owned subsidiary, FirsTech. Busey also has various other subsidiaries that are not significant to the consolidated entity.

***Basis of Financial Statement Presentation***

These unaudited consolidated financial statements and related notes should be read together with the <u>[audited consolidated financial statements](https://www.sec.gov/Archives/edgar/data/314489/000031448925000041/buse-20241231.htm#iee3442b6153849d68ec48ad284abc6f2_220)</u> included in <u>[Busey's 2024 Annual Report](https://www.sec.gov/Archives/edgar/data/0000314489/000031448925000041/buse-20241231.htm)</u>. These interim unaudited consolidated financial statements serve to update Busey's 2024 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements.

Busey's unaudited consolidated financial statements are prepared in conformity with GAAP, and reflect the elimination of intercompany accounts and transactions. Certain prior year amounts have been reclassified to conform to the current period presentation. These reclassifications did not have a material impact on Busey's consolidated financial condition or results of operations.

In the opinion of Busey's management, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly Busey's 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. Critical accounting estimates which are particularly susceptible to significant change in the near term relate to the fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.

**FIRST BUSEY CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

***Cash and Cash Equivalents***

Cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from other banks, and interest-bearing deposits held with other financial institutions. The carrying amount of these instruments is considered a reasonable estimate of fair value. At September 30, 2025, cash and cash equivalents included $13.6 million contractually restricted by a third-party service provider, $14.4 million pledged to secure obligations under derivative contracts, and $68.1 million of reserved cash subject to call by the Federal Reserve Bank, as a member of the Federal Reserve System.

***Leases***

A determination is made at inception if an arrangement contains a lease. For arrangements containing leases, Busey classifies the lease as either operating, finance, or short-term. Busey recognizes operating and finance leases as right of use assets and corresponding lease liabilities. Right of use assets are recognized on the lease commencement date at amounts equal to the respective lease liabilities, adjusted for prepaid lease payments, initial direct costs, and lease incentives received. Lease liabilities are recognized at the present value of the remaining contractual fixed lease payments, discounted using the rate implicit in the lease or Busey's incremental borrowing rate.

ASC Topic 842 "Leases" requires the use of the rate implicit in the lease whenever this rate is readily determinable. If not readily determinable, Busey uses its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. For operating leases existing prior to Busey's adoption of ASC Topic 842 on January 1, 2019, Busey used a borrowing rate that corresponded to the lease term remaining as of the date of adoption of ASC Topic 842.

Busey's lease agreements often include one or more options to renew at Busey's discretion. When Busey considers the exercise of a renewal option to be reasonably certain, contractual fixed lease payments for the renewal term are included in the calculation of the right of use asset and lease liability.

Right of use assets are reviewed for impairment in accordance with Busey's policies regarding long-lived assets.

<u>Operating Leases</u>

Right of use assets for operating leases are included in other assets on the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>. Lease liabilities for operating leases are included in other liabilities on the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>.

Lease costs for operating leases are recognized on a straight-line basis over the lease term. Lease costs are reflected as noninterest expense for net occupancy of premises or for furniture and equipment expenses, as appropriate, on the <u>[Consolidated Statements of Income (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_22)</u>. Variable lease payments are expensed as incurred.

<u>Finance Leases</u>

Right of use assets for finance leases and the related accumulated amortization are included in premises and equipment, net, on the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>. Lease liabilities for finance leases are included in long-term borrowings on the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>. Repayments of the principal portion of finance lease liabilities are reflected as financing activities on the <u>[Consolidated Statements of Cash Flows (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_34)</u>.

Lease costs for finance leases are composed of interest expense and amortization expense. Interest expense on finance leases is reflected as interest expense on long-term borrowings on the <u>[Consolidated Statements of Income (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_22)</u>. Amortization expense on finance leases is reflected as noninterest expense for net occupancy of premises on the <u>[Consolidated Statements of Income (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_22)</u>.

Busey had one finance lease as of September 30, 2025, which was acquired through its acquisition of CrossFirst.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

<u>Short-term Leases</u>

Leases with terms of twelve months or less are classified as short-term leases. Busey made an accounting policy election to not recognize short-term leases on the balance sheet. Lease costs for short-term leases are reflected as noninterest expense for net occupancy of premises or for furniture and equipment expenses, as appropriate, on the <u>[Consolidated Statements of Income (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_22)</u>.

For additional information about Busey's leases, see "*<u>[Note](#id43ca44fb26f43c483ff809287c9b6a0_94)[5. Leases](#id43ca44fb26f43c483ff809287c9b6a0_94)</u>*."

***Income Taxes***

Busey is subject to income taxes in U.S. federal and various state jurisdictions. First Busey Corporation and its subsidiaries file consolidated federal and state income tax returns with each subsidiary computing its taxes on a separate entity basis. Tax regulations within each jurisdiction are subject to the interpretation of the related tax laws and regulations, which requires significant judgment.

On July 4, 2025, new federal tax legislation commonly referred to as the "One Big Beautiful Bill Act" (the "OBBBA") was enacted, which made permanent many of the tax provisions of the 2017 Tax Cuts and Jobs Act that were set to expire in 2025 and introduced several significant amendments to federal tax legislation. Key provisions of the OBBBA include the restoration of immediate expensing of domestic research and development expenditures, reinstatement of 100% bonus depreciation, more favorable rules for determining the limitation on business interest expense, and incentives for financial institutions to increase lending in rural and agricultural communities. The effects of the legislation were reflected in the unaudited consolidated financial statements for the period ending September 30, 2025, and did not have a material impact on our results of operations. Busey will continue evaluating the impact of this legislation for future reporting periods.

As of September 30, 2025, Busey Bank was under examination by the Florida Department of Revenue for its 2020 to 2022 corporate income tax filings. Busey Bank accrued $0.1 million related to potential assessment adjustments and interest. Busey had no accruals for payments of interest and penalties related to uncertain tax positions at September 30, 2025 or 2024.

As of September 30, 2025, Busey was also under examination by the Illinois Department of Revenue for M&M's tax filings for the tax years ended December 31, 2022 and 2023.

***Impact of Recently Adopted Accounting Standards***

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 was adopted on a prospective basis for annual and interim reporting periods beginning January 1, 2025. Busey does not currently have any Profit Interest and Similar Awards, so adoption of this ASU did not have any impact on its financial position or results of operations.

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 was adopted on a retrospective basis beginning with the annual reporting period ending December 31, 2024, and for interim reporting periods within fiscal years starting January 1, 2025. Adoption of this standard did not have a material impact on Busey's financial position or results of operations, but resulted in enhanced disclosures.

***Recently Issued Accounting Standards Not Yet Adopted***

In September 2025, the FASB issued ASU 2025-07 "*Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract,*" to reduce diversity in the application of derivative accounting practices. This update provides a scope limitation on the definition of a derivative subject to derivative accounting under ASC Topic 815, Derivatives and Hedging, to exclude certain non-exchange-traded contracts with contingencies based on operations or activities specific to one of the parties to the contract. In addition, this update clarifies that share-based noncash consideration from a customer that is contingent on the satisfaction of performance obligations should not be recognized at contract inception as a derivative asset or an equity security, but rather should be accounted for under the guidance in ASC Topic 606, Revenue from Contracts with Customers, and that guidance in other topics does not apply to share-based noncash consideration from a customer for the transfer of goods or services unless or until the entity's right to receive or retain the share-based noncash consideration is unconditional under ASC Topic 606. The amendments in this update may be applied on either a prospective or modified retrospective basis, and will be effective for Busey for annual and interim reporting periods beginning January 1, 2027. Early adoption is permitted. Busey is currently evaluating the effect this ASU may have on its financial position and results of operations.

In September 2025, the FASB issued ASU 2025-06 "*Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software*," changing the criteria for capitalizing software costs to the following: (1) a commitment has been made to fund the software project, and (2) it is probable the project will be competed and used to perform its intended function. Under this update, software development stages are no longer a consideration in the determination of which costs are capitalized. The amendments in this update may be adopted on a prospective, modified transition, or retrospective basis, and will be effective for Busey for annual and interim reporting periods beginning January 1, 2028. Early adoption is permitted. Busey is currently evaluating the effect this ASU may have on its financial position and results of operations.

In July 2025, the FASB issued ASU 2025-05 *"Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets,"* providing a practical expedient which, if elected, permits an entity to assume that current conditions as of the balance sheet date will remain static for the remaining life of the assets, removing the requirement to consider reasonable, supportable forecasts. The amendments in this update are to be applied prospectively, and will be effective for Busey for annual and interim reporting periods beginning January 1, 2026. Early adoption is permitted. Busey is currently evaluating the effect this ASU may have on its financial position and results of operations.

In November 2024, the FASB issued ASU 2024-04 "*Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments*" to clarify when certain settlements of convertible debt instruments should be accounted for as an induced conversion. The amendments in this update may be applied on either a prospective or retrospective basis and will be effective for Busey for annual and interim reporting periods beginning January 1, 2026. Because Busey does not currently have any convertible debt, the Company does not expect adoption of this ASU to have any impact on its financial position or results of operations.

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

In November 2024, the FASB issued ASU 2024-03 "*Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses*" to require additional disclosures within the notes to the financial statements about certain expense items. Specifically, disaggregation of income statement captions that contain expenses within the following five categories is required: (1) purchases of inventory, (2) employee compensation, (3) depreciation, (4) intangible asset amortization, and (5) depreciation, depletion, and amortization ("DD&A") costs recognized as part of oil- and gas-producing activities or other amounts of depletion expense. Further, this update requires disclosure of the total amount of selling expenses and the entity's definition of selling expenses. This update provides a practical expedient for banks and bank holding companies to continue presenting salaries and employee benefits in conformity with SEC Rule 210.9-04 instead of requiring those entities to apply the employee compensation definition included in Subtopic 220-40. The amendments in this update may be applied on either a prospective or retrospective basis and will be effective for Busey beginning with the annual reporting period ending December 31, 2027, and interim reporting periods beginning January 1, 2028. Early adoption is permitted. Because this update relates only to disclosure, Busey does not expect adoption of this ASU to have any impact on its financial position or 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 ASU to have a material impact on its 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. If the SEC has not removed the related disclosures from Regulation S-X or Regulation S-K by June 30, 2027, the pending content of this update will be removed from the ASC and will not become effective for any entity. Busey does not expect adoption of this ASU 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. Subsequent to quarter end, on October 24, 2025, Busey issued a conditional notice of full redemption of its $4.0 million 5.25% Subordinated Note maturing December 4, 2030, which was acquired on April 1, 2024, in connection with the acquisition of M&M. The redemption of the Subordinated Note is subject to and conditioned upon regulatory approval from the Federal Reserve. Assuming the requisite approvals are obtained, the Subordinated Note will be redeemed on its optional redemption date of December 4, 2025. Other than this event, there were no significant events subsequent to the quarter ended September 30, 2025, through the filing date of these unaudited consolidated financial statements.

**NOTE 2. MERGERS AND ACQUISITIONS**

***CrossFirst Bankshares, Inc.***

On March 1, 2025, Busey completed its acquisition of CrossFirst (NASDAQ: CFB), the holding company for CrossFirst Bank, pursuant to an <u>[Agreement and Plan of Merger](https://www.sec.gov/Archives/edgar/data/314489/000110465924093098/tm2422366d1_ex2-1.htm)</u>, dated August 26, 2024, by and between Busey and CrossFirst (the "CrossFirst Merger Agreement").

**FIRST BUSEY CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

<u>Merger of CrossFirst Bank into Busey Bank</u>

CrossFirst Bank's results of operations were included in Busey's consolidated results of operations beginning March 1, 2025. Busey operated CrossFirst Bank as a separate banking subsidiary until it was merged with and into Busey Bank on June 20, 2025. At the time of the bank merger, CrossFirst Bank's banking centers became banking centers of Busey Bank.

<u>CrossFirst Merger Consideration</u>

Upon completion of the acquisition, each share of CrossFirst common stock converted into the right to receive 0.6675 of a share of Busey's common stock. Cash was paid in lieu of fractional shares. The fair value of common shares issued in consideration of the CrossFirst acquisition was based on the closing price of Busey's common stock on February 28, 2025.

Further, upon completion of the acquisition, each share of CrossFirst Series A Non-Cumulative Perpetual Preferred Stock converted to the right to receive one share of Busey Series A Preferred Stock. The fair value of Busey Series A Preferred Stock was based on the redemption price of $1,000 per share.

The total consideration paid also included the fair value of replacement equity awards related to past service totaling $6.0 million. Busey used a Monte Carlo simulation to estimate the fair value of SSARs and market-based awards. Other awards were valued based on Busey's closing stock price on February 28, 2025.

<u>Acquisition Accounting</u>

The CrossFirst acquisition was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged were recorded at estimated fair values as of March 1, 2025, the date of acquisition. Subsequent to the acquisition, fair value adjustments of $1.8 million have been recorded, as additional information and valuations became available. Estimated fair values are considered provisional until final fair values are determined or the measurement period has passed, but no later than one year from the acquisition date. Review of all valuations and taxes are still being performed by management. Therefore, amounts are subject to change from the provisional amounts disclosed below.

As the total consideration paid for CrossFirst exceeded the estimated fair value of net assets acquired, goodwill of $49.6 million was recorded as a result of the acquisition. Goodwill recorded for this transaction reflects synergies expected from the acquisition and the greater revenue opportunities from Busey's broader service capabilities in attractive new markets. Goodwill recorded for this transaction is not tax deductible and was assigned to the Banking operating segment.

***Merchants and Manufacturers Bank Corporation***

On April 1, 2024, Busey completed its acquisition of M&M and its wholly-owned subsidiary, M&M Bank, through a merger transaction. This partnership added M&M's Life Equity Loan<sup>®</sup> products to Busey's existing suite of services and expanded Busey's presence in the suburban Chicago market.

<u>Merger of M&M Bank into Busey Bank</u>

M&M Bank's results of operations were included in Busey's results of operation beginning April 1, 2024. Busey operated M&M Bank as a separate banking subsidiary of Busey until it was merged with Busey Bank on June 21, 2024. At the time of the bank merger, M&M Bank's banking centers became banking centers of Busey Bank, except for M&M's banking center located at 990 Essington Rd., Joliet, Illinois, which was closed in connection with the bank merger.

<u>M&M Merger Consideration</u>

At the effective time of the M&M acquisition, 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 M&M 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").

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

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 M&M merger agreement, the 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, 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 M&M 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 M&M acquisition. Fractional shares were paid in cash at the rate of $23.32 per share.

Additional merger consideration of $3.0 million was paid to redeem 300 shares of M&M preferred stock.

<u>Acquisition Accounting</u>

The M&M acquisition was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged were recorded at estimated fair values on April 1, 2024, the date of acquisition. A final fair value adjustment of $0.1 million for deferred taxes was recorded during the three months ended March 31, 2025, in connection with the M&M acquisition. Fair values, including initial accounting for deferred taxes, were subject to refinement for up to one year after the closing date as additional information regarding the closing date fair values became available. Fair values were final as of March 31, 2025.

As the total consideration paid for M&M exceeded the estimated fair value of net assets acquired, goodwill of $15.9 million was recorded as a result of the acquisition. Goodwill recorded for this transaction reflects synergies expected from the acquisition and expansion within the Chicago metropolitan market. Goodwill recorded for this transaction is not tax deductible and was assigned to the Banking operating segment.

***Valuations of Loans***

Estimated fair values for the loan portfolio acquired in the CrossFirst acquisition includes adjustments to certain receivables that were not considered PCD as of the acquisition date. These fair value adjustments were determined using a discounted cash flow model that applies various assumptions about coupon rates, remaining maturities, prepayment speeds, projected default probabilities, losses given defaults, and estimates of prevailing discount rates. These loans did not show signs of deterioration since origination, and therefore, at the acquisition date, were not subject to the guidance related to PCD loans. Receivables acquired in the CrossFirst acquisition that were not subject to these requirements include non-PCD loans with a fair value of $4.70 billion and gross contractual amounts receivable of $4.79 billion.

A portion of acquired loans were PCD. The following table provides a reconciliation between the purchase price and the fair value of these loans:

***Pro Forma Results***

The following unaudited pro forma information has been prepared as if the CrossFirst acquisition had occurred on January 1, 2024, and as if the M&M acquisition had occurred January 1, 2023. The pro forma results combine the historical results of CrossFirst and M&M into Busey's <u>[Consolidated Statements of Income (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_22)</u>, including the impact of purchase accounting adjustments such as loan discount accretion, intangible assets amortization, and deposit accretion, net of taxes. The pro forma results have been prepared for comparative purposes only and are not necessarily indicative of the results that would have been obtained had the acquisitions actually occurred on January 1, 2024, or on January 1, 2023, as applicable. Further, pro forma information does not purport to be indicative of future financial operating results. No assumptions have been applied to the pro forma results of operations regarding possible revenue enhancements, expense efficiencies, or asset dispositions.

Unrealized and unrecognized losses are related to changes in market interest rates and market conditions that do not represent credit-related impairments. Unless part of a corporate strategy or repositioning 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 Busey 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 has been 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 September 30, 2025, Busey did not hold general obligation bonds of any single issuer that exceeded, in aggregate, 10% of Busey's stockholders' equity.

***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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• 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 $2.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $2.0 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.

The following table is a summary of Busey's portfolio loans by risk grade, segregated by loan category:

<u>Performance of Modified Loans</u>

Busey closely monitors the performance of the loans that are modified for borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table depicts the payment performance of loans modified during the last twelve months:

---

| | | | | |
|:---|:---|:---|:---|:---|

| &nbsp;&nbsp;&nbsp;Real estate construction | 5165 |  |  |  |
| Loans modified during the last twelve months | $41374 | $— | $— | $4038 |

---

Busey had commitments of $0.4 million as of September 30, 2025, to lend additional funds to debtors experiencing financial difficulty for whom Busey modified a loan within the past twelve months. Busey did not have any commitments as of December 31, 2024, to lend additional funds to debtors experiencing financial difficulty for whom Busey had modified a loan within the past twelve months.

A default occurs when a loan is 90 days or more past due or transferred to non-accrual status. The following table presents loans that defaulted after having been modified during the twelve months before the default.

---

No loans had a default during the three or nine months ended September 30, 2024, after having been modified during the twelve months before that default for borrowers experiencing financial difficulty.

***Collateral Dependent Loans***

Management's evaluation as to the ultimate collectability of loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. 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 $39.0 million and $19.3 million of collateral dependent loans secured by real estate or business assets as of September 30, 2025, and December 31, 2024, respectively.

***Foreclosures***

Busey's recorded investment in residential real estate loans that were in the process of foreclosure was $6.1 million as of September 30, 2025. Busey follows Federal Housing Finance Agency guidelines on single-family foreclosures and real estate owned evictions on portfolio loans.

***Allowance for Credit Losses***

The ACL is a valuation account that is deducted from the portfolio loans' amortized cost bases to present the net amount expected to be collected on the portfolio loans. The ACL is established through the provision for credit losses charged to income. Portfolio loans are charged off against the ACL when management believes the uncollectibility of a loan balance is confirmed. Recoveries are recognized up to the aggregate amount of previously charged-off balances.

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 ACL consists of three components: (i) specific allocations/individual reserves; (ii) quantitative reserves; and (iii) qualitative reserves.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Specific allocations/individual reserves* – When a loan no longer exhibits risk characteristics that are similar to other loans, that loan is individually evaluated. Individual reserves are calculated for loans that are on a non-accrual status that are greater than a defined dollar threshold or loans that have disparate risk characteristics. Reserves may be based on collateral, for collateral-dependent loans, or on quantitative and qualitative factors, including expected cash flow, market sentiment, and guarantor support.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Quantitative reserves* – Busey implemented a new non-discounted cash flow model in the second quarter of 2025 that used combined historical loan data from Busey Bank beginning in 2004 and CrossFirst Bank since its inception in 2007. The model incorporates various baseline forecast scenarios and national unemployment rates with either national gross domestic product, the national home price index, or the national commercial real estate price index. Further, prepayment and curtailment expectations are factored into the model. 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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Qualitative reserves* – Busey uses qualitative factors to adjust the historical loss factors for current and forecasted conditions. Busey considers the ten qualitative factors identified in the Interagency Guidance and ASC Topic 326 at each reporting date.

The following tables summarize activity in the ACL attributable to each lending activity. Allocation of a portion of the ACL to one lending activity does not preclude its availability to absorb losses from other lending activities:

**NOTE 7. BORROWINGS**

***Securities Sold Under Agreements to Repurchase***

Securities sold under agreements to repurchase, which are classified as secured borrowings, generally mature daily. Securities sold under agreements to repurchase are reflected at the amount of cash received in connection with the transaction. The underlying securities are held by Busey's safekeeping agent. Busey may be required to provide additional collateral based on fluctuations in the fair value of the underlying securities. Securities sold under agreements to repurchase were as follows:

***Revolving Line of Credit***

On May 28, 2021, Busey entered into a Second Amended and Restated Credit Agreement, pursuant to which Busey has access to a $40.0 million revolving line of credit bearing an interest rate of 1.80% plus the one-month forward-looking term rate based on SOFR. After executing subsequent amendments, the current termination date for the revolving line of credit is April 30, 2026. As of September 30, 2025, there was no balance outstanding on the revolving line of credit. The revolving line of credit incurs an insignificant non-usage fee based on any undrawn amounts.

***Short-term Borrowings***

Busey had no short term borrowings as of either September 30, 2025, or December 31, 2024. When applicable, Busey's short-term borrowings include loans maturing within one year of the loan origination date, the current portion of long-term debt that is due within 12 months, and federal funds purchased. Federal funds purchased are short-term borrowings that generally mature between one day and 90 days. During the second quarter of 2025, Busey purchased federal funds to test operational availability to access funds if needed.

***Long-term Borrowings***

Busey's long-term borrowings consist of borrowings maturing more than one year from the loan origination date, excluding the current portion that is due within 12 months, and finance lease liabilities. Long-term borrowings are presented in the table below:

***Subordinated Notes***

On June 1, 2020, Busey issued $125.0 million of fixed-to-floating rate subordinated notes scheduled to mature on June 1, 2030. The subordinated notes, which qualified as Tier 2 capital for regulatory purposes, bore interest at an annual rate of 5.25% for the first five years after issuance. Thereafter, the notes were to bear interest at a floating rate equal to a three-month benchmark rate plus a spread of 5.11%, as calculated on each applicable determination date. The subordinated notes, which were unsecured obligations of the Company, had an optional redemption, in whole or in part, on any interest payment date on or after June 1, 2025. On June 1, 2025, Busey redeemed the entire $125.0 million outstanding principal amount of the subordinated notes.

On June 2, 2022, Busey issued $100.0 million aggregate principal amount of 5.000% fixed-to-floating rate subordinated notes maturing June 15, 2032, which qualify as Tier 2 capital for regulatory purposes. The price to the public for the subordinated notes was 100% of the principal amount of the subordinated notes. Interest on the subordinated notes accrues at a rate equal to (1) 5.000% per annum from the original issue date to, but excluding, June 15, 2027, payable semiannually in arrears, and (2) a floating rate per annum equal to a benchmark rate, which is the Three-Month Term SOFR (as defined in the subordinated notes), plus a spread of 252 bps from and including June 15, 2027, payable quarterly in arrears. The subordinated notes have an optional redemption, in whole or in part, on any interest payment date on or after June 15, 2027.

Associated with the M&M acquisition completed on April 1, 2024 (see *"<u>[Note 2. Mergers and Acquisitions](#id43ca44fb26f43c483ff809287c9b6a0_46)</u>"*), Busey acquired a $4.0 million 5.25% fixed-to-floating rate subordinated note maturing December 4, 2030, which qualified as Tier 2 capital for regulatory purposes. Interest on the subordinated note accrues at a rate equal to (1) 5.25% per annum from the original issue date to December 4, 2025, and (2) a floating rate per annum equal to a benchmark rate, which is the Three-Month Term SOFR (as defined in the subordinated notes), plus a spread of 497 bps from December 4, 2025. At September 30, 2025, there was an immaterial amount of fair value discount outstanding, to be accreted through the earliest optional redemption date. The subordinated note has an optional redemption, in whole or in part, on or after December 4, 2025. Subsequent to quarter end, on October 24, 2025, Busey issued a conditional notice of full redemption of this subordinated note. The redemption of the subordinated note is subject to and conditioned upon regulatory approval from the Federal Reserve. Assuming the requisite approvals are obtained, the subordinated note will be redeemed on its optional redemption date of December 4, 2025.

**NOTE 8. REGULATORY CAPITAL**

First Busey and its subsidiary 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 First Busey's consolidated financial statements. Capital amounts and classification also are subject to qualitative judgments by regulators about components, risk weightings, and other factors.

***Capital Conservation Buffer***

In July 2013, U.S. federal banking authorities approved the Basel III Rule for strengthening international capital standards. 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%, which First Busey exceeded by 533 bps as of September 30, 2025, (2) Tier 1 capital to risk-weighted assets of at least 8.5%, which First Busey exceeded by 527 bps as of September 30, 2025, and (3) total capital to risk-weighted assets of at least 10.5%, which First Busey exceeded by 539 bps as of September 30, 2025.

**NOTE 10. STOCK-BASED COMPENSATION**

***CrossFirst Acquisition***

The CrossFirst acquisition impacted Busey and CrossFirst equity awards:

<u>Treatment of Busey's Equity Awards</u>

Following the closing of the CrossFirst acquisition, except as otherwise provided in the CrossFirst Merger Agreement, Busey equity awards generally remain outstanding and subject to the same terms and conditions as applied immediately prior to the time at which the CrossFirst acquisition became effective (the "effective time"). Notable changes to Busey's equity awards are as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• ROATCE PSUs* — Each PSU issued by Busey that is earned based on Core Return on Average Tangible Common Equity (the "ROATCE PSUs") and was outstanding immediately prior to the effective time was deemed earned with the achievement of the applicable performance goals based on actual performance through December 31, 2024, the latest practicable date prior to the effective time, and otherwise remains subject to the same terms and conditions (including service-based vesting terms) as applied to such ROATCE PSUs immediately prior to the effective time. The ROATCE PSUs have been deemed earned (i) at 100% of the target level of performance, for the ROATCE PSUs granted in 2023 and (ii) at 75% of the target level of performance, for the ROATCE PSUs granted in 2024.

**FIRST BUSEY CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• TSR PSUs* — Each Busey PSU previously granted that is tied to total stockholder return ("TSR", and such PSUs, the "TSR PSUs") with a performance period that ended December 31, 2024, (excluding TSR PSUs previously held by retirees) was replaced, and each TSR PSU outstanding immediately prior to the effective time with performance periods ending December 31, 2025, and December 31, 2026, (including existing TSR PSUs held by retirees) was modified, each effective March 1, 2025, such that the resulting new or modified PSUs (collectively, the "Merger PSUs") will be earned based on Busey's relative TSR rank as compared to the KBW Regional Banking Index, measured at the end of a performance period commencing January 1, 2025, and ending December 31, 2026. The Merger PSUs are subject to the terms and conditions of Busey's Amended 2020 Equity Incentive Plan and the applicable award agreements. The target number of PSUs subject to each such Merger PSU was determined based on the number of PSUs that would have been earned in respect of the corresponding TSR PSU had performance for such corresponding TSR PSU been determined based on actual performance as of August 26, 2024, the day immediately prior to the announcement of the Merger, which is (i) in the case of the 2022 TSR PSUs, 94.5% of the original target level of performance, (ii) in the case of the 2023 TSR PSUs, 96.2% of the original target level of performance, and (iii) in the case of the 2024 TSR PSUs, 76.9% of the original target level of performance. Such target number also reflects the number of dividend equivalents accrued in respect of the corresponding existing TSR PSU that would have been earned based on the same actual TSR performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Busey RSUs* — Each outstanding Busey time-based restricted stock unit award (the "Busey RSUs") will vest in equal annual installments over three (3) years following the effective time; provided that if any Busey RSU would otherwise vest by its terms on an earlier date, any then-unvested portion as of such date shall vest on such original vesting date.

Each Busey equity award will be subject to double-trigger vesting upon an involuntary termination within twelve (12) months following the effective time (at target performance, in the case of Merger PSUs).

<u>Treatment of CrossFirst's Equity Awards</u>

Equity awards based on CrossFirst Common Stock that were outstanding immediately prior to the effective time were converted, at the effective time, either to Busey Common Stock or to equity awards based on Busey Common Stock, as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• Director equity awards* — Each CrossFirst restricted stock award held by a CrossFirst non-employee director and each deferred share of CrossFirst Common Stock that was credited to a director participant's account under the CrossFirst 2018 Directors' Deferred Fee Plan was converted into the right to receive 0.6675 shares of Busey Common Stock (the "Exchange Ratio").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• CrossFirst RSUs* — Each CrossFirst time-based restricted stock unit award ("CrossFirst RSU") was converted into a restricted stock unit in respect of Busey Common Stock (a "Busey RSU") based on the Exchange Ratio, rounded to the nearest whole share, subject to the same terms and conditions as were applicable to the CrossFirst RSUs prior to the effective time.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• CrossFirst PSUs* — Each CrossFirst performance-based restricted stock unit award ("CrossFirst PSU") was converted into a time-based Busey RSU based on the Exchange Ratio, subject to the same terms and conditions as were applicable to the CrossFirst PSUs prior to the effective time, assuming the achievement of the applicable performance goals based on, for the CrossFirst PSUs granted in 2023, actual performance through December 31, 2024, and, for the CrossFirst PSUs granted in 2024, target performance, rounded to the nearest whole share.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• CrossFirst SSARs* — Each CrossFirst SSAR was converted into a stock appreciation right in respect of Busey Common Stock based on the Exchange Ratio, rounded down to the nearest whole share (and exercise price rounded up to the nearest cent), generally subject to the same terms and conditions as were applicable to the CrossFirst SSAR prior to the effective time.

***Stock Settled Appreciation Rights***

Busey issued replacement awards in the form of SSARs as part of the acquisition of CrossFirst. These awards were issued under the CrossFirst Bankshares 2018 Omnibus Equity Incentive Plan with exercise prices equal to the closing price of CrossFirst's common shares on the original date for each award adjusted by the Exchange Ratio of 0.6675, rounded up to the nearest cent. At grant, SSARs typically vested ratably over seven years of continuous service with a ten-year or fifteen-year contractual term. At grant, replacement SSARs had a weighted average remaining contractual term of 5.4 years, and unvested replacement SSARs had a weighted average remaining vesting period of 3.2 years. The fair value of each SSAR was estimated at acquisition date using a Monte Carlo simulation since the awards were all in-the-money. The fair value of SSARs that have vested during 2025 was $3.6 million.

&nbsp;&nbsp;&nbsp;&nbsp;1. The aggregate intrinsic value of SSARs exercised during 2025 was $1.1 million.

The following table provides the range of assumptions used in the Monte Carlo simulations to value CrossFirst awards that were replaced at acquisition, the weighted average grant date fair value, and information related to SSARs exercised for the indicated periods, as well as the remaining compensation cost to be recognized and the period over which the amount will be recognized as of the dates indicated:

---

| | |
|:---|:---|
| *(dollars in thousands, except per share amounts)* | **Nine Months Ended September 30, 2025** |
| **Assumptions** |  |
| &nbsp;&nbsp;&nbsp;Expected volatility<sup>1</sup> | 29.10% – 36.70% |
| &nbsp;&nbsp;&nbsp;Expected dividends<sup>2</sup> | 4.17% |
| &nbsp;&nbsp;&nbsp;Simulation term<sup>3, 4, 5</sup> | 4.20 years – 5.69 years |
| &nbsp;&nbsp;&nbsp;Risk-free rate<sup>6</sup> | 3.97% – 4.03% |
| Weighted average grant date fair value per share | $8.94 |

---

___________________________________________

&nbsp;&nbsp;&nbsp;&nbsp;1.Expected volatility was calculated using a historical volatility of Busey's stock price over a period commensurate with the simulation term of the SSARs.

&nbsp;&nbsp;&nbsp;&nbsp;2.The dividend yield was calculated using Busey's annual dividend and closing stock price on the date of acquisition.

&nbsp;&nbsp;&nbsp;&nbsp;3.The simulation term was commensurate with the midpoint of the longest expected term across all SSARs and was impacted by expected exercise behavior and termination rate.

&nbsp;&nbsp;&nbsp;&nbsp;4.As a component of determining the simulation term, exercise was assumed to occur at the earlier of the midpoint of i) the greater of the weighted average time to vest or the time the options are in the money, and the time the SSARs expire, ii) 90 days following the occurrence of a termination, or iii) the end of the contractual term.

&nbsp;&nbsp;&nbsp;&nbsp;5.As a component of determining the simulation term, termination rate was assumed to be between 25% and 50% in the first year following the acquisition and 5% for every year thereafter.

&nbsp;&nbsp;&nbsp;&nbsp;6.The risk-free rate for the simulation term of the SSARs was based on the continuously compounded semi-annual zero-coupon U.S. Treasury rates.

***2020 Equity Plan***

Busey has granted RSU, PSU, and DSU awards under the terms of its 2020 Equity Plan. Upon vesting and delivery, shares are expected, though not required, to be issued from treasury stock. There were 685,515 shares available for issuance under the 2020 Equity Plan as of September 30, 2025.

A description of RSU, PSU, and DSU awards granted in 2025 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.

<u>RSU Awards</u>

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 represents the future right to receive one share of Busey's common stock. 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 26, 2025, under the terms of the 2020 Equity Plan, Busey granted 348,269 RSUs to members of management. The grant date fair value of the award was $7.7 million, which will be recognized as compensation expense over the requisite service period. These awards will vest in equal installments on each of the first three anniversaries of the grant date. The terms of these awards included an accelerated vesting provision upon eligible retirement from Busey, after a one-year minimum requisite service period.

On May 29, 2025, under the terms of the 2020 Equity Plan, Busey granted 4,494 RSUs to members of management. The grant date fair value of the award was $0.1 million, which will be recognized as compensation expense over the requisite service period. These awards will vest in equal installments on each of the first three anniversaries of the grant date.

On July 23, 2025, under the terms of the 2020 Equity Plan, Busey granted 13,724 RSUs to members of management. The grant date fair value of the award was $0.3 million, which will be recognized as compensation expense over the requisite service period. These awards will vest on July 23, 2028.

A summary of changes in Busey's RSU awards for the nine months ended September 30, 2025, is as follows:

---

<u>PSU Awards</u>

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 for the applicable performance period and providing continuous service through the end of such performance period. Each PSU represents the future right to receive one share of Busey's common stock. The number of PSUs that ultimately vest will be determined based on the extent to which the established performance criteria 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 1, 2025, under the terms of the 2020 Equity Plan, in connection with the CrossFirst acquisition, Busey granted a target of 59,471 Merger PSUs to replace the 2022 TSR PSUs with a maximum award of 95,154 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 relative total stockholder return performance goal. The grant date fair value of the award, calculated using the Geometric Brownian Motion Model, is $1.3 million, which will be recognized in compensation expense over the performance period ending December 31, 2026.

On March 26, 2025, under the terms of the 2020 Equity Plan, Busey granted a target of 174,126 PSUs with a maximum award of 278,602 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 relative total stockholder return performance goal. The grant date fair value of the award, calculated using the Geometric Brownian Motion Model, is $3.4 million, which will be recognized in compensation expense over the performance period ending December 31, 2027.

On March 26, 2025, under the terms of the 2020 Equity Plan, Busey granted a target of 174,126 PSUs with a maximum award of 278,602 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 $3.9 million, which will be recognized in compensation expense over the performance period ending December 31, 2027. The actual amount of compensation expense recognized for these awards is subject to adjustment based on the extent to which performance goals are expected to be achieved.

A summary of changes in Busey's PSU awards for the nine months ended September 30, 2025, is as follows:

---

&nbsp;&nbsp;&nbsp;&nbsp;2.Modifications include PSUs that were converted to RSUs as well as balance adjustments related to the 2023 TSR PSUs and the 2024 TSR PSUs.

<u>DSU Awards</u>

Busey grants DSU awards to its non-employee directors. DSU awards are stock-based awards with a deferred settlement date. Each DSU represents the future right to receive 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 26, 2025, under the terms of the 2020 Equity Plan, Busey granted 39,846 DSUs to non-employee directors. The grant date fair value of the award totaled $0.9 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.

***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.

***Franchise Tax Matter***

In 2021, Busey received an inquiry from the Illinois Secretary of State, pursuant to which the Illinois Secretary of State asked for additional information regarding certain of Busey's 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 delivered additional BCA forms requested by the Illinois Secretary of State, 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.

**FIRST BUSEY CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

On March 20, 2025, the Illinois Secretary of State requested that Busey resubmit the requested forms using a proposed methodology for paid-in capital that Busey views as inconsistent with the Illinois Secretary of State's past practice, and existing statutory and case law. Accordingly, on May 14, 2025, within the Illinois Secretary of State's requested timeframe, Busey informed the Illinois Secretary of State that it would not resubmit the requested forms with the methodology that Busey disputes and requested that the parties instead continue good faith discussions. On July 2, 2025, Busey received a notice of hearing from the Illinois Secretary of State indicating that an administrative hearing has been scheduled to "ascertain" the required amount of franchise taxes, penalties, interest, fees, and charges purportedly due from Busey to the Illinois Secretary of State. In the notice, the Illinois Secretary of State requested a determination of an amount due that the Illinois Secretary of State preliminarily estimated to be in excess of $28 million, including in excess of $17.4 million in interest and in excess of $0.3 million in penalties. Busey disagrees with the Illinois Secretary of State's preliminary estimate and believes that the Illinois Secretary of State's request is contrary not only to the Illinois Secretary of State's past practice, but also existing statutory and case law. Busey intends to vigorously defend itself against the Illinois Secretary of State's notice, including through appropriate judicial relief, if necessary. On July 31, 2025, First Busey filed a special appearance with the Illinois Secretary of State's Department of Administrative Hearings solely for the limited purpose of contesting the jurisdiction of the Illinois Secretary of State to initiate and conduct the administrative hearing.

Where a loss is believed to be reasonably possible, but not probable, or the loss cannot be reasonably estimated, no accrual is required. Given the underlying disagreement between Busey and the Illinois Secretary of State on the proper methodology for calculating any franchise tax owed, the loss cannot be reasonably estimated. It is reasonably possible that this matter could require Busey 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 September 30, 2025. If the likelihood of potential liabilities elevates and Busey becomes able to reasonably estimate the loss, requiring an accrual, the potential future liabilities could be material in the period(s) in which they are recorded.

**NOTE 12. 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 and risk participation agreements with customers and other third parties. See "*<u>[Note 13: Fair Value Measurements](#id43ca44fb26f43c483ff809287c9b6a0_124)</u>*" 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)* | **September 30,<br>2025** | **December 31,<br>2024** |
| Cash pledged to secure obligations under derivative contracts | $14400 | $21900 |
| Collateral held to secure obligations under derivative contracts | 8140 | 20260 |

---

***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.

<u>Interest Rate Swaps Designated as Cash Flow Hedges</u>

Interest rate swaps with notional amounts totaling $500.0 million as of both September 30, 2025, and December 31, 2024, were designated as cash flow hedges. Busey entered into a $300.0 million receive-fixed, pay-floating interest rate swap to reduce Busey's asset sensitivity (Prime Loan Swap). Duration was added to Busey's 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, Busey entered into forward-starting SOFR-based receive-fixed pay-floating interest rate swaps totaling $200.0 million to reduce Busey's asset sensitivity (SOFR Loan Swaps). 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. Changes in the fair value of these interest rate swaps were recorded net of tax in OCI.

A summary of the interest-rate swaps designated as cash flow hedges is presented below:

***Derivative Instruments Not Designated as Hedges***

<u>Interest Rate Swaps Not Designated as Hedges</u>

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 $1.01 billion as of September 30, 2025, and $719.2 million as of December 31, 2024. 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.

<u>Risk Participation Agreements</u>

To manage the credit risk exposure related to customer-facing swaps, Busey entered into risk participation agreements in conjunction with loan participation arrangements with other financial institutions. Under these risk participation agreements, Busey purchased credit risk participation, paying an up-front fee to a counterparty to accept a portion of its credit exposure, and will receive a payment from the counterparty if the swap customer defaults on its obligations. Busey also assumed additional risk participation agreements entered into by CrossFirst, in which CrossFirst purchased credit risk participation, and Busey will receive a payment from the counterparty if the swap customer defaults on its obligations.

In connection with the CrossFirst acquisition, Busey assumed risk participation agreements entered into by CrossFirst, under which CrossFirst sold credit risk participation, receiving an up-front fee from a counterparty in exchange for accepting a portion of the counterparty's credit exposure. Under these agreements, Busey will be required to make a payment to the counterparty if the swap customer defaults on its obligations.

***Mortgage Banking Derivatives***

<u>Interest Rate Lock Commitments</u>

Interest rate lock 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 on the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>, with changes in the fair values of the corresponding derivative financial assets or liabilities recorded as either a charge or credit to current earnings during the period in which the changes occurred.

<u>Forward Sales Commitments</u>

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 on the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>.

**NOTE 13. 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *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, volatility, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

**FIRST BUSEY CORPORATION**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Level 3 Inputs*—Unobservable inputs for estimating 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 estimates are based upon quoted market prices, when available. If such quoted market prices are not available, fair values are estimated utilizing independent valuation techniques that consider 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 their estimated fair values. 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 estimate 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***

<u>Debt Securities Available for Sale</u>

Debt securities classified as available for sale are reported at fair value, which is estimated using 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.

<u>Equity Securities</u>

Equity securities are reported at fair value, which is estimated using Level 1 or Level 2 inputs. Fair value measurements of mutual funds or stock in active markets are estimated using unadjusted quoted prices for identical assets at the measurement date and are classified as Level 1. Fair value measurements of stock that are not active use quoted prices for identical or similar assets in markets and are classified as Level 2.

<u>Derivative Assets and Derivative Liabilities</u>

Busey's derivative assets and derivative liabilities are reported at fair value, which is measured using Level 2 or Level 3 inputs. Fair values of derivative assets and liabilities are estimated based on prices that are obtained from a third-party which uses observable market inputs and, with the exception of risk participation agreements, are classified as Level 2. Due to the significance of unobservable inputs, derivative assets and liabilities related to risk participation agreements are classified as Level 3.

***Assets and Liabilities Measured at Fair Value on a Nonrecurring Basis***

Certain financial assets and financial liabilities are measured at estimated fair value on a non-recurring basis; that is, the instruments are not measured at estimated fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

<u>Loans Evaluated Individually</u>

Busey does not record portfolio loans at estimated fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the estimated fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the estimated 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.

<u>OREO and Other Repossessed Assets</u>

Non-financial assets measured at fair value, upon initial recognition or subsequent impairment, include OREO and other repossessed assets. OREO properties and other repossessed assets are measured using a combination of observable inputs, including recent appraisals, and unobservable inputs. Due to the significance of unobservable inputs, the estimated fair values of all OREO and other repossessed assets have been classified as Level 3.

<u>Bank Property Held for Sale</u>

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 estimated fair value less estimated costs to sell. Fair value estimates were based upon discounted appraisals or real estate listing prices. Due to the significance of unobservable inputs, estimated fair values of all bank property held for sale have been classified as Level 3. Bank property held for sale is included in premises and equipment, net on Busey's <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>.

**NOTE 14. EARNINGS PER COMMON SHARE**

Basic earnings per common share is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding, which include DSUs that are vested but not delivered. Net income available to common stockholders is net income less dividends that have been declared on Busey's preferred stock (all of which is non-cumulative). Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if Busey's outstanding stock options and SSARs were exercised, stock units were vested, and ESPP shares were issued.

Earnings per common share have been computed as follows:

**MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Unaudited)**

<u>Busey's East Region</u>

Busey Bank serves the suburban Chicago market with 17 banking centers, offering a full spectrum of financial services to individuals and businesses. The Chicago area is home to several Fortune 500 companies, featuring a diverse economic mix that includes manufacturing, logistics, information technology, and financial services. With a regionalized approach and a legacy of service excellence, Busey remains a trusted financial partner to the vibrant communities of northeastern Illinois.

Busey Bank operates 20 banking centers in the St. Louis MSA, including eight banking centers in eastern Missouri and 12 banking centers in western Illinois. St. Louis has a diverse economy and major employment sectors that include healthcare, financial services, professional and business services, and retail. Busey continues to build on its legacy of serving dynamic urban and suburban markets in the region.

Busey Bank serves the southwest Florida banking market with three banking centers located in and around Fort Myers, an area which has experienced strong population growth, job expansion, and a vibrant housing market, as well as the benefits of a robust tourism and winter resort economy. These factors have contributed to a thriving environment for consumer banking and small business services.

<u>Busey's Midwest Region</u>

Busey Bank serves the central Illinois banking market with 21 banking centers. The economy of central Illinois is agriculture-based, with a prominent presence of manufacturing and services industries. These industries, 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 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. Its strategic location and infrastructure have fostered steady economic performance, positioning Busey to meet the financial needs of both retail and commercial clients.

<u>Busey's Central Region</u>

Busey Bank serves the Kansas City MSA with three banking centers, including two locations in Leawood, Kansas and one in Kansas City, Missouri. The Kansas City MSA is a diverse and economically vibrant region, supported by industries such as healthcare, financial services, manufacturing, and transportation. Leawood is known for its desirable residential communities and concentration of corporate offices and financial institutions, while the Missouri location provides connectivity to the area's broader commercial and industrial base. Together, these banking centers position Busey to serve a wide range of consumer and business clients across one of the Midwest's most dynamic metropolitan regions.

Busey Bank operates one banking center in Wichita, Kansas, the state's largest city and a key regional economic hub. Wichita's economy is anchored by its leadership in aviation, aerospace engineering, and manufacturing, along with growing healthcare and education footprints that contribute to a stable employment base and expanding residential development. Busey's presence in Wichita enables Busey Bank to serve a diverse mix of consumer and commercial clients in a market known for its industrial strength and community resilience.

Busey Bank serves the Oklahoma banking market with three banking centers, including two in Oklahoma City and one in Tulsa.

**MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Unaudited)**

<u>Busey's Texas Region</u>

Busey Bank operates four banking centers across the Dallas-Fort Worth MSA, including locations in Dallas, Frisco, and Fort Worth, Texas. The Dallas-Fort Worth MSA is the most populous metropolitan area in the southern United States, and serves as a key business and financial hub with a diverse economy spanning technology, healthcare, telecommunications, and logistics. The region's rapid population growth, entrepreneurial energy, and deep talent pool have created strong demand for housing and commercial expansion, aligning well with Busey's financial services model.

<u>Busey's West Region</u>

Busey Bank has two banking centers in Arizona, located in Phoenix and Tucson. Phoenix, a fast-growing metropolitan area, features a broad-based economy with key sectors in advanced manufacturing, fintech, and education. Tucson, supported by a strong university presence and a vibrant tourism sector, has seen steady growth in small business development and residential communities. Busey's presence supports a range of financial needs in both urban and suburban settings.

Busey Bank has three banking centers in Colorado, located in Denver and Colorado Springs. Denver stands out as a major economic center with thriving industries in technology, energy, and financial services, while Colorado Springs offers a more suburban environment anchored by defense, aerospace, and healthcare sectors. Both cities have experienced consistent population growth and infrastructure investment, creating opportunities for Busey to serve a dynamic customer base.

Busey Bank operates one banking center in Clayton, New Mexico. Located in northeastern New Mexico, Clayton's economy is primarily driven by agricultural, cattle ranching, and small-scale retail, with steady contributions from transportation services due to its proximity to major highways. The community also benefits from local tourism linked to nearby parks and attractions. Busey's presence supports essential financial needs in this rural market, reinforcing its commitment to serving both metropolitan and underserved areas with tailored banking solutions.

<u>Busey's Verticals</u>

Transcending geographical boundaries, Busey operates in several industry verticals, including Life Equity Lending, Sponsor Finance, Energy Lending, and SBA Lending.

***Busey's Conservative Banking Strategy***

Busey's financial strength is built on a long-term conservative operating approach. The quality of Busey's core deposit franchise is a critical value driver of the institution. Busey remains substantially core deposit<sup>1</sup> funded, with robust liquidity and significant market share in the communities it serves. As of September 30, 2025, Busey's loan to deposit ratio was 90.2% and core deposits represented 93.8% of total deposits. Furthermore, Busey has sufficient on- and off-balance sheet liquidity to manage deposit fluctuations and the liquidity needs of its customers.

Busey's credit performance reflects its highly diversified, conservatively underwritten loan portfolio, which has been originated predominantly to established customers with tenured relationships with Busey. Busey's approach to lending and its underwriting standards are designed to emphasize relationship banking rather than transactional banking. In addition, as a matter of both policy and practice, Busey limits concentration exposures in any particular loan segment.

Busey's conservative banking strategy is reflected in the strength of its capital base. Busey strives 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. As of September 30, 2025, Busey's leverage ratio of Tier 1 capital to average assets was 11.6%, its common equity Tier 1 capital to risk weighted assets ratio was 12.3%, and its total capital to risk weighted assets ratio was 15.9%.

<sup>1</sup> Core deposits is a non-GAAP financial measure. For a reconciliation of non-GAAP measures to the most directly comparable GAAP financial measures, see *<u>["Item 2. Management's Discussion and Analysis—Non-GAAP Financial Information"](#id43ca44fb26f43c483ff809287c9b6a0_220)</u>* included in this Quarterly Report.

***Mergers and Acquisitions***

<u>CrossFirst Bankshares, Inc.</u>

On March 1, 2025, Busey completed its acquisition of CrossFirst and its wholly-owned subsidiary, CrossFirst Bank. This partnership creates a premier commercial bank with 79 full-service locations across 10 states.

CrossFirst Bank's results of operations were included in Busey's results of operations beginning March 1, 2025. Busey operated CrossFirst Bank as a separate banking subsidiary until it was merged with and into Busey Bank on June 20, 2025. At the time of the bank merger, CrossFirst Bank's banking centers became banking centers of Busey Bank.

***Non-GAAP Adjusting Items and Non-GAAP Measures***

Busey views certain non-operating items, including acquisition-related expenses, restructuring charges, and nonrecurring strategic events, as adjustments to net income reported under GAAP. We also adjust for net securities gains and losses to align with industry and research analyst reporting. The objective of our presentation of adjusted earnings and adjusted earnings metrics is to allow investors and analysts to more clearly identify quarterly trends in core earnings performance. Pre-tax non-GAAP adjustments were as follows:

___________________________________________

&nbsp;&nbsp;&nbsp;&nbsp;1.During the nine months ended September 30, 2024, Busey executed a two-part balance sheet repositioning strategy in which it sold mortgage servicing rights on approximately $923.5 million of one-to-four family mortgage loans for a pre-tax gain of $7.7 million and sold available-for-sale debt securities with a book value of approximately $108.2 million for a pre-tax loss of $6.8 million.

&nbsp;&nbsp;&nbsp;&nbsp;2.During the nine months ended September 30, 2025, in connection with the CrossFirst acquisition, Busey's recorded expense for the initial provision for credit losses consisting of a Day 2 provision for loan losses of $42.4 million, a Day 2 provision for unfunded commitments of $3.1 million, and an adjustment to the initial provision for unfunded commitments of $4.0 million that was recorded based on revised estimates resulting from implementation of a new CECL model.

&nbsp;&nbsp;&nbsp;&nbsp;3.Other acquisition expenses related to the acquisition of CrossFirst, which was completed on March 1, 2025, and the acquisition of M&M, which was completed on April 1, 2024.

&nbsp;&nbsp;&nbsp;&nbsp;4.Restructuring expenses were related to previously disclosed restructuring and efficiency plans.

A reconciliation of non-GAAP measures, which Busey believes facilitates the assessment of its financial results and peer comparability, is included in tabular form in this Quarterly Report.

&nbsp;&nbsp;&nbsp;&nbsp;4.Beginning in the second quarter of 2025, Busey revised its presentation, for all periods presented, to reclassify the provision for unfunded commitments so that it is now included within the provision for credit losses, affecting the calculation of pre-provision net revenue and related measures and ratios.

***Net Interest Income***

Net interest income is the difference between interest income and fees earned on loans and investments ("interest-earning assets") and interest expense incurred on deposits and borrowings ("interest-bearing liabilities"). Interest rate levels and volume fluctuations within interest-earning assets and interest-bearing liabilities impact net interest income. Net interest margin is tax-equivalent net interest income as a percent of average interest-earning assets.

**MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Unaudited)**

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.

<u>Consolidated Average Balance Sheets and Interest Rates</u>

&nbsp;&nbsp;&nbsp;&nbsp;2.Net interest income expressed as a percentage of average earning assets, stated on a tax-equivalent basis.

Busey continues to evaluate and execute off-balance sheet hedging and balance sheet strategies as well as embedding rate protection in our asset originations to provide stabilization to net interest income in lower rate environments. Stability in core deposit balances, as well as retail time deposit and savings specials, have continued to provide sufficient funding flows to allow intentional runoff of brokered and high-cost, non-relationship funding. During the three months ended September 30, 2025, Busey executed a strategic targeted reduction of $794.6 million high-cost, non-relationship deposits bearing a weighted average cost of 4.45%, including $228.2 million of brokered deposits.

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:

Total noninterest income was $41.2 million for the three months ended September 30, 2025, an increase of 14.9% from the comparable period in 2024, as we benefit from the CrossFirst acquisition and extend services into new markets. Total noninterest income was $107.3 million for the nine months ended September 30, 2025, an increase of 2.7% from the comparable period in 2024. The nine months ended September 30, 2025, includes seven months of income from the CrossFirst acquisition, offset by net securities losses that were recorded in the first quarter of 2025 in connection with a strategic balance sheet repositioning. Additionally, the prior year included $7.7 million of realized net gains on the sale of mortgage servicing rights, which was not repeated in the current year.

Wealth management fees were $17.2 million for the three months ended September 30, 2025, an 11.7% increase from the comparable period in 2024, and were $51.3 million for the nine months ended September 30, 2025, a 9.6% increase from the comparable period for 2024, primarily due to increases in trust fee income. On a segment basis, Busey's Wealth Management division contributed $17.4 million, or 42.2%, of Busey's noninterest income for the three months ended September 30, 2025, which included approximately $0.2 million reported as other noninterest income, and contributed $51.9 million, or 48.4%, of Busey's noninterest income for the nine months ended September 30, 2025, which included approximately $0.6 million reported as other noninterest income. Busey's Wealth Management division ended the third quarter of 2025 with $14.96 billion in assets under care, an increase of 9.3% compared to the balance on September 30, 2024. Busey's portfolio management team continues to focus on long-term returns and managing risk in the face of volatile markets.

**MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Unaudited)**

Payment technology solutions relates to Busey's payment processing company, FirsTech. Income from payment technology solutions was $5.1 million for the three months ended September 30, 2025, a 3.3% decrease from the comparable period in 2024, and was $15.1 million for the nine months ended September 30, 2025, a 10.5% decrease from the comparable period in 2024, primarily due to decreases in income from online bill payments. On a segment basis, FirsTech contributed $5.5 million, or 13.4%, of Busey's noninterest income for the three months ended September 30, 2025, and $16.3 million, or 15.2%, of Busey's noninterest income for the nine months ended September 30, 2025.

Combined, noninterest income from wealth management fees and payment technology solutions represented 54.1% and 61.9% of Busey's noninterest income for the three and nine months ended September 30, 2025, respectively, providing a complement to spread-based revenue from traditional banking activities.

Treasury management services consist primarily of business analysis charges and wire transfer fees on commercial accounts. Income from treasury management services increased by 108.9% and 101.6% compared to the three and nine months ended September 30, 2024, respectively, due to the addition of CrossFirst commercial services.

Card services and ATM fees, which include both commercial and consumer accounts, increased by 34.9% and 34.6% compared to the three and nine months ended September 30, 2024, respectively, primarily due to addition of CrossFirst corporate card services.

Other service charges on deposit accounts were $1.6 million for the three months ended September 30, 2025, a 32.3% decline from the comparable period in 2024, and were $4.7 million for the nine months ended September 30, 2025, a decline of 33.9% from the comparable period in 2024. Declines were largely related to lower non-sufficient fund charges, reflecting changes Busey made to its fee structure in 2025.

Mortgage revenue was $0.7 million for the three months ended September 30, 2025, an 85.1% increase from the comparable period in 2024, and was $1.8 million for the nine months ended September 30, 2025, an 11.6% increase from the comparable period in 2024. General economic conditions and interest rate volatility may impact future mortgage revenue.

Income on bank owned life insurance was $1.6 million for the three months ended September 30, 2025, a 36.5% increase from the comparable period in 2024, as a result of a $0.5 million increase in the cash surrender value of the policies, partially offset by a $0.1 million decrease in earnings on death proceeds. Income on bank owned life insurance was $4.8 million for the nine months ended September 30, 2025, an 18.9% increase from the comparable period in 2024, as a result of a $1.3 million increase in the cash surrender value of the policies, partially offset by a $0.5 million decrease in earnings on death proceeds.

During the nine months ended September 30, 2025, Busey did not record any realized gains on the sale of mortgage servicing rights. In comparison, during the nine months ended September 30, 2024, Busey recognized a $7.7 million gain on the sale of mortgage servicing rights in connection with a strategic two-part balance sheet repositioning. For more information, see *"<u>[Busey executed a two-part balance sheet repositioning strategy](https://www.sec.gov/Archives/edgar/data/314489/000031448924000157/buse-20240331.htm#i40058eeafc0048118a3e9fc955695ee1_1266)</u>*" in the Management Discussion and Analysis included in Busey's Quarterly Report for the first quarter of 2024, filed with the SEC on May 7, 2024.

Net securities losses were $0.3 million for the three months ended September 30, 2025, a decrease from the net securities gains from the comparable period in 2024. Net securities losses of $10.1 million during the nine months ended September 30, 2025, were greater than the net securities losses realized during the comparable period in 2024. Losses for the nine months ended September 30, 2025, were comprised of $15.5 million of realized net losses on securities associated with a strategic balance sheet repositioning in the first quarter of 2025, partially offset by second quarter unrealized net gains on Busey's approximately 3% equity ownership of a financial institution that was the target of an announced acquisition at a significant market premium.

Other noninterest income was $5.9 million for the three months ended September 30, 2025, a 25.7% increase from the comparable period in 2024, and was $13.7 million for the nine months ended September 30, 2025, a 36.4% increase from the comparable period in 2024. Increases were primarily attributable to fluctuations in income recognized on private equity investments, commercial loan servicing income, swap origination fees, and syndication fees.

&nbsp;&nbsp;&nbsp;&nbsp;1.The efficiency ratio and adjusted efficiency ratio are non-GAAP financial measures. For a reconciliation of non-GAAP measures to the most directly comparable financial GAAP measures, see *"<u>[Item 2. Management's Discussion and Analysis—Non-GAAP Financial Information](#id43ca44fb26f43c483ff809287c9b6a0_220)</u>"* included in this Quarterly Report.

Total noninterest expense was $120.0 million for the three months ended September 30, 2025, a 58.9% increase from the comparable period in 2024. Total noninterest expense was $359.9 million for the nine months ended September 30, 2025, a 61.5% increase from the comparable period in 2024. Growth in noninterest expense was primarily attributable to acquisition and restructuring expenses related to the CrossFirst acquisition, added costs for operating expenses for two banks from March 1, 2025, until the banks were merged on June 20, 2025, and increased expenses associated with Busey's larger organization and expanded branch network. Acquisition and restructuring expenses contributed $7.2 million to total noninterest expense for the three months ended September 30, 2025, compared to $1.9 million for the comparable period in 2024. Acquisition and restructuring expenses contributed $49.8 million to total noninterest expense for the nine months ended September 30, 2025, compared to $4.6 million for the comparable period in 2024.

Annual pre-tax expense synergy estimates resulting from the CrossFirst acquisition remain on track at $25.0 million. Busey anticipates a 50% rate of synergy realization in 2025 and 100% in 2026.

Busey uses an accelerated amortization methodology.

Interchange expense was $1.3 million for the three months ended September 30, 2025, a 1.2% decrease from the comparable period in 2024, and was $4.0 million for the nine months ended September 30, 2025, a 15.3% decrease from the comparable period in 2024. Fluctuations in interchange expense relate to payment and volume activity at FirsTech.

FDIC insurance expense was $3.2 million for the three months ended September 30, 2025, a 123.0% increase from the comparable period in 2024, and $7.7 million for the nine months ended September 30, 2025, an 81.2% increase from the comparable period in 2024.

Other noninterest expense was $14.1 million for the three months ended September 30, 2025, a 51.6% increase from the comparable period in 2024, and was $39.4 million for the nine months ended September 30, 2025, a 37.5% increase from the comparable period in 2024. Increases in other noninterest expense are attributable to multiple items, including marketing, business development, and supplies, as well as increases in acquisition and restructuring expenses of $0.4 million and $1.4 million compared to the three and nine months ended September 30, 2024, respectively.

<u>Efficiency Ratio</u>

The efficiency ratio<sup>2</sup>, which is a measure commonly used by management and the banking industry, measures the amount of expense incurred to generate a dollar of revenue. Busey's efficiency ratio was 58.5% for the three months ended September 30, 2025, compared to 61.8% for the same period in 2024, and was 65.4% for the nine months ended September 30, 2025, compared to 61.1% for the same period in 2024.

Busey's adjusted efficiency ratio<sup>2</sup> was 54.9% for the three months ended September 30, 2025, compared to 60.2% for the same period in 2024, and was 56.0% for the nine months ended September 30, 2025, compared to 61.1% for the same period in 2024.

<u>Taxes</u>

Busey's effective income tax rate of 26.1% for the three months ended September 30, 2025, aligning with a combined federal and state statutory rate of approximately 26%. Busey's effective income tax rate of 31.7% for the nine months ended September 30, 2025, was impacted by the remeasurement of deferred tax assets acquired in the CrossFirst acquisition, discrete adjustments related to equity award vestings, and other non-recurring adjustments.

Busey continues to monitor evolving federal and state tax legislation and its potential impact on operations on an ongoing basis. As of September 30, 2025, Busey Bank was under examination by the Florida Department of Revenue for its 2020 to 2022 corporate income tax filings and by the Illinois Department of Revenue for M&M's tax filings for the tax years 2022 and 2023.

<sup>2</sup> The efficiency ratio and adjusted efficiency ratio are non-GAAP financial measures.

***Portfolio Loans***

Busey believes that making sound and profitable loans is a necessary and desirable means of employing funds available for investment. 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, Busey attempts to focus its lending on short to intermediate-term loans (0-10 years) in geographic areas within 125 miles of its lending offices. Busey seeks 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. Busey's 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.

At no time is a borrower's total borrowing relationship permitted to exceed Busey Bank's regulatory lending limit. Busey generally limits 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 Busey's loan policy on a periodic basis. In addition, the loan review department reviews risk assessments made by Busey's 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 can be summarized into five primary lending activities, which can be further categorized as either commercial or retail lending. Commercial lending activities consist of C&I and other commercial loans, CRE loans, and real estate construction loans while retail lending activities consist of retail real estate loans and retail other loans. A description of each of the five primary areas can be found in *"<u>[Item 7.

Total portfolio loans were $13.60 billion at September 30, 2025, compared to $7.70 billion at December 31, 2024. The $5.90 billion growth in the loan portfolio during the first nine months of 2025 was primarily attributable to the CrossFirst acquisition. Busey remains steadfast in its conservative approach to underwriting and disciplined approach to pricing. During the third quarter of 2025, the Company experienced elevated payoffs that outpaced new production momentum. Busey expects continued pressure, particularly from commercial real estate payoffs through the remainder of 2025.

<u>Allowance for Credit Losses and Provision for Loan Losses</u>

The ACL is a significant estimate on Busey's unaudited consolidated financial statements, affecting both earnings and capital. The methodology adopted influences, and is influenced by, Busey'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 the collectability as of the evaluation date. The ACL is established through the provision for credit loss expense charged to income. Provision for loan losses expenses were recorded as follows:

___________________________________________

&nbsp;&nbsp;&nbsp;&nbsp;1.The nine months ended September 30, 2025, included $42.4 million to establish an initial allowance for loan losses in connection with the CrossFirst acquisition.

The $3.3 million provision reversal for loan losses recorded during the three months ended September 30, 2025, included a provision release of $7.1 million for PCD loans due to payoffs/paydowns and provision expense of $3.8 million for non-PCD loans to support charge-offs and qualitative factor adjustments. The provision for loan losses for the nine months ended September 30, 2025, included $42.4 million of provision expense recorded to establish an initial allowance for non-PCD loans immediately following the close of the CrossFirst acquisition in accordance with ASC 326-20-30-15.

As of September 30, 2025, management believed the level of the ACL to be appropriate based upon the information available. However, additional losses may be identified in the loan portfolio as new information is obtained. Factors that influence Busey's calculation of its ACL include changes in economic conditions and forecasts, originated and acquired loan portfolio composition, credit performance trends, portfolio duration, and other factors.

<u>Non-Performing Loans and Non-Performing Assets</u>

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 Busey's interest in the underlying collateral less estimated costs to sell. Busey's loan portfolio is collateralized primarily by real estate.

**FIRST BUSEY CORPORATION**

**MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Unaudited)**

Busey's total assets grew by 51.0% to $18.19 billion as of September 30, 2025, compared to $12.05 billion as of December 31, 2024, largely in connection with the CrossFirst acquisition. Further, Busey's loan portfolio grew by 76.7% to $13.60 billion as of September 30, 2025, compared to $7.70 billion as of December 31, 2024.

Asset quality continues to be strong. Following the CrossFirst Bank Merger in June, Busey is operating as one bank, with a singular credit policy, concentration limits, and monitoring that will continue to align with Busey's pillars of credit quality. Busey's operating mandate and focus remain on emphasizing credit quality over asset growth.

Non-performing loan balances increased to $47.5 million as of September 30, 2025, compared to $23.2 million as of December 31, 2024, primarily due to PCD loans assumed in the CrossFirst acquisition. Non-performing loans represented 0.35% of portfolio loans as of September 30, 2025, compared to 0.30% as of December 31, 2024. Busey's allowance for credit losses provided coverage of 3.67 times non-performing loans at September 30, 2025, compared to 3.59 times at December 31, 2024.

Non-performing assets, which include non-performing loans, OREO, and other repossessed assets, increased to $57.7 million as of September 30, 2025, compared to $23.3 million as of December 31, 2024, primarily due to PCD loans assumed in the CrossFirst acquisition. Non-performing assets represented 0.32% of total assets as of September 30, 2025, compared to 0.19% as of December 31, 2024. Busey's allowance for credit losses provided coverage of 3.02 times non-performing assets at September 30, 2025, compared to 3.58 times at December 31, 2024.

Classified assets, which include non-performing assets and substandard loans, increased to $161.1 million as of September 30, 2025, compared to $85.3 million as of December 31, 2024, primarily due to PCD loans assumed in the CrossFirst acquisition. Classified assets represented 7.03% of the Bank's Tier 1 capital and ACL at September 30, 2025, compared to 5.61% at December 31, 2024.

Net charge-offs totaled $5.8 million and $50.2 million for the three and nine months ended September 30, 2025, respectively, compared to $0.2 million and $15.3 million for the comparable periods in 2024. Net charge-offs for the nine months ended September 30, 2025, include $35.5 million related to PCD loans acquired from CrossFirst Bank, which were fully reserved at acquisition and did not require recording additional provision expense.

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, Busey would expect the credit quality of its loan portfolio to decline and loan defaults to increase.

<u>Potential Problem Loans</u>

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 $103.3 million as of September 30, 2025, compared to $62.0 million as of December 31, 2024. Management continues to monitor these loans and work with the borrowers on restructurings, guarantees, additional collateral, or other planned actions. As of September 30, 2025, management identified no other loans that represent or result from trends or uncertainties that would be expected to materially impact future operating results, liquidity, or capital resources.

***Deposits***

Total deposits increased by 51.0% to $15.07 billion as of September 30, 2025, compared to $9.98 billion as of December 31, 2024, in connection with the CrossFirst acquisition. Busey focuses on deepening its customer relationships to maintain and protect its strong core deposit<sup>3</sup> franchise. Core deposits include non-brokered transaction accounts, money market and savings deposit accounts, and time deposits of $250,000 or less. Core deposits represented 93.8% of total deposits as of September 30, 2025.

<sup>3</sup> Core deposits is a non-GAAP financial measure. For a reconciliation of non-GAAP measures to the most directly comparable GAAP financial measures, see *<u>["Item 2. Management's Discussion and Analysis—Non-GAAP Financial Information"](#id43ca44fb26f43c483ff809287c9b6a0_220)</u>* included in this Quarterly Report.

**MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS (Unaudited)**

Deposits are federally insured up to the FDIC insurance limit of $250,000. When a portion of a deposit account exceeds the FDIC insurance limit, that portion is uninsured. Estimated uninsured deposits were $6.45 billion, or 43% of total deposits, as of September 30, 2025, compared to $3.78 billion, or 38% of total deposits, as of December 31, 2024. Excluding intercompany accounts, fully collateralized accounts (including preferred deposits), and pass-through accounts where clients have deposit insurance at the correspondent financial institution, the portion of Busey's deposit base that was uninsured and not otherwise collateralized was $5.31 billion, or 35% of total deposits, as of September 30, 2025, compared to $2.96 billion, or 30% of total deposits, as of December 31, 2024.

***Liquidity***

Liquidity management is the process by which Busey ensures that adequate liquid funds are available to meet the present and future cash flow obligations arising in the daily operations of its 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. Busey's most liquid assets are cash and due from banks, interest-bearing bank deposits, and federal funds sold. Balances of these assets are dependent on Busey's operating, investing, lending, and financing activities during any given period.

Average liquid assets are summarized in the table below:

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 Bank, and Busey's revolving credit facility, as summarized in the table below:

---

| | | |
|:---|:---|:---|

| &nbsp;&nbsp;&nbsp;Revolving credit facility | 40000 | 40000 |
| Additional borrowing capacity | $4042824 | $2861046 |

---

Further, Busey could utilize brokered deposits as additional sources of liquidity, as needed.

As of September 30, 2025, management believed that adequate liquidity existed to meet all projected cash flow obligations. Busey seeks 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 Busey's outstanding commitments and reserves for unfunded commitments:

---

| | | |
|:---|:---|:---|
| | **As of** | **As of** |
| *(dollars in thousands)* | **September 30,<br>2025** | **December 31,<br>2024** |
| Outstanding loan commitments and standby letters of credit | $4898745 | $2548178 |
| Reserve for unfunded commitments | 16123 | 5967 |

---

___________________________________________

&nbsp;&nbsp;&nbsp;&nbsp;1.The nine months ended September 30, 2025, included $7.2 million to establish an initial allowance for unfunded commitments in connection with the CrossFirst acquisition.

Busey anticipates that it 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***

Busey's capital ratios are in excess of those required to be considered "well-capitalized" pursuant to applicable regulatory guidelines. The Federal Reserve 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 its subsidiary bank as of September 30, 2025:

---

| | | | |
|:---|:---|:---|:---|
| | **Minimum Capital Requirements with<br>Capital Buffer** | **As of September 30, 2025** | **As of September 30, 2025** |
| | **Minimum Capital Requirements with<br>Capital Buffer** | **First<br>Busey** | **Busey<br>Bank** |
| Common equity Tier 1 capital to risk weighted assets | 7.00% | 12.33% | 13.73% |
| Tier 1 capital to risk weighted assets | 8.50% | 13.77% | 13.73% |
| Total capital to risk weighted assets | 10.50% | 15.89% | 14.67% |
| Leverage ratio of Tier 1 capital to average assets | 6.50% | 11.62% | 11.59% |

**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. Busey believes the adjusted measures are useful for investors and management to understand the effects of certain non-core and non-recurring noninterest items and provide additional perspective on Busey's performance over time.

Non-GAAP disclosures have inherent limitations and are not audited. They should not be considered in isolation or as a substitute for the results reported in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Tax effected numbers included in these non-GAAP disclosures are based on estimated federal income tax rates or effective tax rates as noted with the tables below.

The following tables present reconciliations between these non-GAAP measures and what management believes to be the most directly comparable GAAP financial measures.

___________________________________________

1. The Day 2 provision represents the initial provision for credit losses recorded in connection with the CrossFirst acquisition to establish an allowance on non-PCD loans and unfunded commitments and is reflected within the provision for credit losses line on the Statement of Income.

2. In the second quarter of 2025, Busey recorded an adjustment to the initial provision for unfunded commitments for CrossFirst acquisition-date balances based on revised estimates resulting from implementation of a new Current Expected Credit Losses model.

3. Tax benefits were calculated for the year-to-date periods using tax rates of 26.64% and 22.21% for the nine months ended September 30, 2025 and 2024, respectively. Tax benefits for the quarterly periods were calculated as the year-to-date tax amounts less the tax reported for previous quarters during the year.

4. A deferred valuation tax adjustment in 2025 was recorded in connection with the CrossFirst acquisition and the expansion of Busey's footprint into new states. Additionally, 2025 includes a write-off of deferred tax assets related to non-deductible compensation and acquisition-related expenses. A deferred tax valuation adjustment in 2024 resulted from a change to Busey's Illinois apportionment rate due to recently enacted regulations. Deferred tax adjustments are reflected within the income taxes line on the Statement of Income.

5. Beginning in 2025, Busey revised its calculation of adjusted net income for all periods presented to include, as applicable, adjustments for net securities gains and losses, realized net gains and losses on the sale of mortgage servicing rights, and one-time deferred tax valuation adjustments. In 2024, these adjusting items were presented as further adjustments to adjusted net income.

&nbsp;&nbsp;&nbsp;&nbsp;1.Tax-equivalent adjustments were calculated using an estimated federal income tax rate of 21.0%, applied to non-taxable interest income on investments and loans.

&nbsp;&nbsp;&nbsp;&nbsp;2.Beginning in the second quarter of 2025, Busey revised its presentation, for all periods presented, to reclassify the provision for unfunded commitments so that it is now included within the provision for credit losses; therefore, it is no longer included within total noninterest expense. This change affects all measures and ratios derived from total noninterest expense.

**FORWARD-LOOKING STATEMENTS**

This Quarterly Report may contain "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to Busey's financial condition, results of operations, plans, objectives, future performance, and business. 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," "position," or other similar expressions. Additionally, all statements in this document, 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 Busey's ability 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 economies and financial markets (including effects of a prolonged government shut-down, inflationary pressures, the threat or implementation of tariffs, trade wars, and changes to immigration policy); (2) changes in, and the interpretation and prioritization of, local, state, and federal laws, regulations, and governmental policies (including those concerning Busey's general business); (3) 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 conflict in the Middle East); (4) unexpected results of acquisitions, including the acquisition of CrossFirst, which may include the failure to realize the anticipated benefits of the acquisitions and the possibility that the transaction and integration costs may be greater than anticipated; (5) the imposition of tariffs or other governmental policies impacting the value of products produced by Busey's commercial borrowers; (6) new or revised accounting policies and practices as may be adopted by state and federal regulatory banking agencies, the Financial Accounting Standards Board, the Securities and Exchange Commission, or the Public Company Accounting Oversight Board; (7) changes in interest rates and prepayment rates of Busey's assets (including the impact of sustained elevated interest rates); (8) increased competition in the financial services sector (including from non-bank competitors such as credit unions, private credit, and fintech companies) and the inability to attract new customers; (9) technological changes implemented by us and other parties, including our third-party vendors, which may have unforeseen consequences to us and our customers, including the development and implementation of tools incorporating artificial intelligence; (10) the loss of key executives or associates, talent shortages, and employee turnover; (11) unexpected outcomes and costs of existing or new litigation, investigations, or other legal proceedings, inquiries, and regulatory actions involving Busey (including with respect to Busey's Illinois franchise taxes); (12) fluctuations in the value of securities held in Busey's securities portfolio, including as a result of changes in interest rates; (13) credit risk and risk from concentrations (by type of borrower, geographic area, collateral, and industry), within Busey's loan portfolio and large loans to certain borrowers (including commercial real estate loans); (14) the concentration of large deposits from certain clients who have balances above current Federal Deposit Insurance Corporation 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; (18) the economic impact on Busey and its customers of climate change, natural disasters, and exceptional weather occurrences such as tornadoes, hurricanes, floods, blizzards, and droughts; (19) the ability to successfully manage liquidity risk, which may increase dependence on non-core funding sources such as brokered deposits, and may negatively impact Busey's cost of funds; (20) the ability to maintain an adequate level of allowance for credit losses on loans; (21) the effectiveness of Busey's risk management framework; and (22) the ability of Busey to manage the risks associated with the foregoing. 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 including <u>[Busey's 2024 Annual Report](https://www.sec.gov/Archives/edgar/data/314489/000031448925000041/buse-20241231.htm)</u>.

**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 *"<u>[Note 1. Significant Accounting Policies](https://www.sec.gov/Archives/edgar/data/314489/000031448925000041/buse-20241231.htm#iee3442b6153849d68ec48ad284abc6f2_241)</u>"* of <u>[Busey's 2024 Annual Report](https://www.sec.gov/Archives/edgar/data/314489/000031448925000041/buse-20241231.htm)</u>.

<u>[**Table of Contents**](#id43ca44fb26f43c483ff809287c9b6a0_7)</u>

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 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 Busey's critical accounting estimates. Management has reviewed these critical accounting estimates and related disclosures with Busey's Audit Committee. The following estimates could be deemed critical:

***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." The determination of fair values is based on valuations using management's assumptions of future growth rates, future attrition, discount rates, multiples of earnings, or other relevant factors. In addition, Busey engages third party specialists to assist in the development of fair values.

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. Goodwill is not amortized; instead, Busey assesses the potential for impairment on an annual basis or more frequently if events and circumstances indicate that goodwill might be impaired. Management applies significant judgment when testing goodwill for impairment, such as the valuation approach chosen, market multiples for competitors used in the calculation, and forecasts of business outlook.

***Income Taxes***

Busey is subject to the income tax laws of U.S., as well as the tax laws of the individual states and municipalities in which the Company conducts its operations. These laws are often complex and subject to nuanced interpretations.

Income taxes are estimated for the tax effects of the transactions reported on Busey's unaudited consolidated financial statements and consist of an expense for taxes currently due plus assets and/or liabilities for deferred taxes. Deferred taxes represent the future tax consequences of differences between the tax basis and accounting basis of certain assets and liabilities, which will either be taxable or deductible when the assets and liabilities are recovered or settled. Deferred tax assets and liabilities are estimates that are reflected at income tax rates applicable to the period in which the deferred tax assets or liabilities are expected to be realized or settled. Deferred taxes are reported in other assets or other liabilities on the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u>. Estimated income tax expense is reported on the <u>[Consolidated Statements of Income (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_22)</u>.

First Busey Corporation (BUSE) \| **113**

<u>[**Table of Contents**](#id43ca44fb26f43c483ff809287c9b6a0_7)</u>

In establishing its provision for income taxes and its estimates of deferred tax assets and liabilities, Busey must make judgments and interpretations about the application of inherently complex tax laws. Busey must also make estimates about when in the future certain items will affect taxable income. Disputes over interpretations of the tax laws may be subject to review and adjudication by the court systems of the various tax jurisdictions or may be settled with the taxing authority upon examination or audit. Although Busey's management believes that its judgments are sound and its tax estimates are reasonable, interpretations of tax law applied by the taxing jurisdictions could differ. As such, Busey may be exposed to losses or gains, which could be material. An unfavorable tax settlement would result in an increase in Busey's effective income tax rate in the period of resolution. A favorable tax settlement would result in a reduction in Busey's effective income tax rate in the period of resolution.

***Allowance for Credit Losses***

Busey calculates the ACL at each reporting date. Busey recognizes an allowance for the lifetime expected credit losses for the amount it does 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, Busey 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. Macroeconomic forecasts provided by a third party and the economic indices sourced are significant judgments used in determining the allowance. Changes in these economic forecasts could significantly affect the ACL and lead to materially different amounts from one period to the next. Additionally, prepayment assumptions impact model output. Further, Busey completes a quarterly evaluation of several qualitative factors to determine if there should be adjustments made to the ACL. These factors include economic conditions, collateral, concentrations, delinquency trends, portfolio composition, underwriting, and certain other risks. Significant downturns relating to loan quality and economic conditions could result in a requirement for an additional allowance. Likewise, an upturn in loan quality and improved economic conditions may allow for a reduction in the required allowance. 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 a minimal impact or do not arise in the normal course of Busey's business activities.

Busey has an asset-liability committee, whose policy is to meet at least quarterly, to review current market conditions and to structure the <u>[Consolidated Balance Sheets (Unaudited)](#id43ca44fb26f43c483ff809287c9b6a0_19)</u> to optimize stability in net interest income in consideration of projected future changes in interest rates.

First Busey Corporation (BUSE) \| **114**

------

<u>[**Table of Contents**](#id43ca44fb26f43c483ff809287c9b6a0_7)</u>

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 and +/-200 bps. 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-One: Basis Point Changes** | **Year-Two: Basis Point Changes** | **Year-Two: Basis Point Changes** |
| | **September 30,<br>2025** | **December 31,<br>2024** | **September 30,<br>2025** | **December 31,<br>2024** |
| +200 | 2.30% | 4.05% | 3.20% | 5.24% |
| +100 | 2.03% | 1.96% | 2.61% | 2.59% |
| -100 | (1.31)% | (1.81)% | (2.53)% | (3.35)% |
| -200 | (1.57)% | (3.39)% | (4.42)% | (6.65)% |

---

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.

**ITEM 4. CONTROLS AND PROCEDURES**

**EVALUATION OF DISCLOSURE CONTROLS AND PROCEDURES**

An evaluation of Busey's disclosure controls and procedures, as defined in Rule 13a-15(e) under the Exchange Act, was carried out as of September 30, 2025, under the supervision and with the participation of its Chief Executive Officer, Chief Financial Officer, and several other members of senior management. Based on this evaluation, Busey's Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2025, Busey's disclosure controls and procedures were effective in ensuring that the information Busey is required to disclose in the reports Busey files or submits under the Exchange Act was (1) accumulated and communicated to Busey's management (including the Chief Executive Officer and Chief Financial Officer) to allow timely decisions regarding required disclosure, and (2) recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms.

**CHANGES IN INTERNAL CONTROL OVER FINANCIAL REPORTING**

During the three months ended September 30, 2025, no change occurred in Busey's internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, Busey's internal control over financial reporting.
