Busey's Conservative Banking Strategy

Busey’s financial strength is built on a long-term conservative operating approach. The quality of Busey’s core deposit1 franchise is a critical value driver of the institution. Busey remains substantially core deposit funded, with robust liquidity. As of June 30, 2026, Busey’s loan to deposit ratio was 87.2% and core deposits represented 93.7% of total deposits. Busey maintains 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. 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 June 30, 2026, Busey’s leverage ratio of Tier 1 capital to average assets was 11.9%, its common equity Tier 1 capital to risk weighted assets ratio was 12.5%, and its total capital to risk weighted assets ratio was 16.1%.

Business Combinations

CrossFirst Bankshares, Inc.

On March 1, 2025, Busey completed its acquisition of CrossFirst and its wholly-owned subsidiary, CrossFirst Bank. This transformative partnership helped create a premier commercial bank spanning 10 states.

CrossFirst Bank’s results of operations were included in Busey’s results of operations beginning March 1, 2025. First 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.

Further information regarding Busey’s acquisitions is provided in Note 2. Business Combinations in the Notes to the Consolidated Financial Statements (Unaudited).

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. Busey also adjusts for net securities gains and losses to align with industry and research analyst reporting. The objective of Busey’s 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:

___________________________________________

1.During the six months ended June 30, 2025, Busey sold available for sale debt securities with a book value of approximately $205.6 million for a pre-tax loss of $15.5 million and related estimated tax benefit of $4.3 million, as part of a balance sheet repositioning strategy.

2.During the six months ended June 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, and a Day 2 provision for unfunded commitments of $3.1 million. During the three and six months ended June 30, 2025, Busey recorded a $4.0 million adjustment to the initial provision for unfunded commitments for CrossFirst acquisition-date balances based on revised estimates resulting from implementation of a new CECL model.

3.Other acquisition expenses related to the acquisition of CrossFirst, which was completed on March 1, 2025. Final expenses for the acquisition of M&M were also included for 2025.

4.Restructuring expenses were incurred in connection with the execution on additional synergies related to the CrossFirst acquisition and also in connection with the previously announced departure of Michael J. Maddox in the first quarter of 2026.

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 MD&A. See “Non-GAAP Financial Information.”

BUSEY’S CONSERVATIVE BANKING STRATEGY

Busey’s financial strength is built on a long-term conservative operating approach. The quality of Busey’s core deposit1 franchise is a critical value driver of the institution. Busey remains substantially core deposit funded, with robust liquidity. As of December 31, 2025, Busey’s loan to deposit ratio was 91.0% and core deposits1 represented 93.7% 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. 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. While impacted by loans acquired as a result of the CrossFirst acquisition, asset quality remains strong by both Busey’s historical and current industry trends.

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. At December 31, 2025, Busey’s leverage ratio of Tier 1 capital to average assets was 11.9%, its common equity Tier 1 capital to risk weighted assets ratio was 12.4%, and its total capital to risk weighted assets ratio was 15.9%.

CRITICAL ACCOUNTING ESTIMATES

Busey has established various accounting policies that govern the application of GAAP in the preparation of its Consolidated Financial Statements. Significant accounting policies are described in “Note 1. Significant Accounting Policies” in the Notes to the Consolidated Financial Statements.

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 the 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 the 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 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 Consolidated Balance Sheets. Estimated income tax expense is reported on the Consolidated Statements of Income.

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-off 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.
