LEAWOOD, KS, October 28, 2025 (GLOBE NEWSWIRE) – First Busey Corporation (Nasdaq: BUSE) Announces 2025 Third Quarter Earnings.

Net Income |  | Diluted EPS |  | Net Interest Margin(1) |  | ROAA(1) |  | ROATCE(1)
$57.1 million $62.5 million (adj)(2) |  | $0.58 $0.64 (adj)(2) |  | 3.58% 3.45% (adj)(2) |  | 1.21% 1.33% (adj)(2) |  | 11.96% 13.20% (adj)(2)

MESSAGE FROM OUR CHAIRMAN & CEO |  | CONTENTS |
We continued to optimize our balance sheet to be more efficient and profitable with adjusted return on average assets(2) improving to 1.33% and net interest margin(2) expanding 9 basis points to 3.58% in the third quarter, driven by the intentional runoff of $794.6 million high-cost, non-relationship deposits with a weighted average cost of 4.45%. Deposit costs continued to fall as spot deposit cost at the end of the quarter improved 21 basis points to 2.01%, an 84% beta versus the September rate cut. Capital remained strong and Common Equity Tier 1 Capital(3) grew to 12.33%. Tangible common equity to tangible assets(2) grew to 9.9%, with tangible book value per common share(2) increasing 10.1% since year end even as we continued to repurchase stock at attractive levels. Credit quality showed improvement with classified assets as a percentage of capital falling to 7.0% and net charge-offs at 0.17%. Loan balances fell modestly as higher than anticipated payoffs impacted the quarter. As we look ahead to the end of the year, we expect our balance sheet optimization to be largely complete and for relative stability in loans and deposits as we continue to execute on our disciplined organic growth strategy.

___________________________________________
1. 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.
Busey views certain non-operating items, including acquisition-related expenses, restructuring charges, and nonrecurring strategic events, as adjustments to net income reported under U.S. generally accepted accounting principles ("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:

Adjusted net income available to common stockholders,(2) which excludes the impact of non-GAAP adjustments, was $57.4 million, or $0.64 per diluted common share, for the third quarter of 2025, compared to $57.2 million, or $0.63 per diluted common share, for the second quarter of 2025 and $32.9 million, or $0.57 per diluted common share, for the third quarter of 2024. Annualized adjusted return on average assets(2) and annualized adjusted return on average tangible common equity(2) were 1.33% and 13.20%, respectively, for the third quarter of 2025.
During the third quarter of 2025, dividends on preferred stock included the first dividend on Busey’s 8.25% Fixed-Rate Series B Non-Cumulative Perpetual Preferred Stock (“Series B Preferred Stock”). Based on the Certificate of Designation, dividends on the Series B Preferred Stock are calculated on the basis of a 360-day year of twelve 30-day months. This first dividend was calculated from the issuance date of May 20, 2025; therefore, it included additional days that resulted in additional dividends of $0.5 million in the third quarter, which is not expected to recur.
Pre-Provision Net Revenue(2)
Pre-provision net revenue(2) was $76.6 million for the third quarter of 2025, compared to $64.2 million for the second quarter of 2025 and $42.2 million for the third quarter of 2024. Pre-provision net revenue to average assets(2) was 1.63% for the third quarter of 2025, compared to 1.35% for the second quarter of 2025, and 1.40% for the third quarter of 2024.
Adjusted pre-provision net revenue(2) was $83.9 million for the third quarter of 2025, compared to $80.8 million for the second quarter of 2025 and $44.1 million for the third quarter of 2024. Adjusted pre-provision net revenue to average assets(2) was 1.78% for the third quarter of 2025, compared to 1.70% for the second quarter of 2025 and 1.46% for the third quarter of 2024.

1. On a tax-equivalent basis and assuming a federal income tax rate of 21.0%.
2. Non-accrual loans have been included in average portfolio loans.
3. Includes, as applicable, short-term borrowings, long-term borrowings, subordinated notes, and junior subordinated debt owed to unconsolidated trusts.
4. Annualized.
5. For a reconciliation of non-GAAP measures to the most directly comparable GAAP financial measures, see “Non-GAAP Financial Information.”
Components of the 9 basis point increase in net interest margin(2) during the third quarter of 2025 were as follows:
•New and renewed loans continued to price at higher spreads, contributing +8 basis points
•Reduced funding costs on deposits, as we benefited from actions taken to reduce high-cost, non-relationship deposits, contributed +7 basis points
•Remaining benefit from the May 20, 2025, issuance of preferred stock and the June 1, 2025, subordinated debt redemption contributed +5 basis points
•Reduced rates and volume on cash and securities portfolio contributed -6 basis points
•Reduced purchase accounting accretion contributed -3 basis points
•Impact of fixed borrowing expenses contributed -2 basis points
First Busey Corporation (BUSE) | 2025 Q3 — 5

Based on our most recent Asset Liability Management Committee model, a -100 basis point parallel rate shock is expected to decrease net interest income by 1.3% (relative to a current base rate scenario) over the subsequent twelve-month period. 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 with no incremental short-term borrowing during the quarter. This strategic targeted reduction of $794.6 million deposits bearing a weighted average cost of 4.45% included $228.2 million of brokered deposits. At September 30, 2025, the Bank had $125.4 million, or 0.8% of total deposits, of remaining brokered funding. Total deposit cost of funds decreased, as expected, from 2.21% during the second quarter of 2025 to 2.15% during the third quarter of 2025. At September 30, 2025, our spot rate on total deposits costs was 2.01%, compared to 2.22% at June 30, 2025.

Total noninterest income decreased by 8.2% compared to the second quarter of 2025 primarily due to a decrease in gains on net securities, as Busey recorded a second quarter gain on its approximately 3% equity ownership of a financial institution that was the target of an announced acquisition at a significant market premium. Compared to the third quarter of 2024, total noninterest income increased by 14.9% as we benefit from the CrossFirst acquisition and extend services into new markets.
Busey continues to benefit from its diverse set of product offerings. Wealth management fees, wealth management referral fees included in other noninterest income, payment technology solutions, treasury management services, and corporate credit card interchange income contributed 67.9% of noninterest income excluding net securities gains and losses(2) for the third quarter of 2025.
Noteworthy changes in noninterest income during the quarter include:
•Wealth management fees increased by 2.4% compared to the second quarter of 2025 primarily due to increases in trust and estate fees, partially offset by seasonally lower tax preparation fees. Busey’s Wealth Management division ended the third quarter of 2025 with $14.96 billion in assets under care, compared to $14.10 billion at the end of the second quarter of 2025 and $13.69 billion at the end of the third quarter of 2024. Our portfolio management team continues to focus on long-term returns and managing risk in the face of volatile markets and has outperformed its blended benchmark(4) over the last three and five years.
•Other noninterest income increased by $2.7 million, or 82.7%, compared to the second quarter of 2025, primarily due to gains on private equity investments and increased swap origination fee income.

Compared to the prior year, growth in noninterest expense was primarily attributable to nonrecurring acquisition expenses related to the CrossFirst acquisition and increased expense associated with the combined organization and branch network. Annual pre-tax expense synergy estimates resulting from the CrossFirst acquisition remain on track at $25.0 million, and we expect 50% of the identified synergies to be realized in 2025 and 100% in 2026.
Adjusted noninterest expense,(2) which excludes acquisition and restructuring expenses and amortization of intangible assets, was $108.3 million in the third quarter of 2025, a 1.6% increase compared to $106.6 million in the second quarter of 2025 and a 52.5% increase compared to $71.0 million in the third quarter of 2024.
Noteworthy changes in noninterest expense during the quarter include:
•Salaries, wages, and employee benefits expenses declined by $4.2 million compared to the second quarter of 2025, with acquisition and restructuring expenses declining by $5.9 million. Compared to the third quarter of 2024, salaries, wages, and employee benefits expenses increased by $29.6 million, of which $5.5 million was attributable to increases in acquisition and restructuring expenses. In connection with the CrossFirst acquisition in March 2025 and the addition of 16 banking centers, Busey’s workforce expanded, with a net addition of 412 full-time equivalent associates over the past year.
•Data processing expense declined by $4.3 million compared to the second quarter of 2025, of which $3.5 million was attributable to decreases in acquisition and restructuring expenses. Additionally, synergies were realized resulting from the bank merger late in the second quarter. When compared with the third quarter of 2024 data processing expense increased by $2.8 million, of which $0.3 million was attributable to increases in acquisition and restructuring expenses. Busey has continued to make investments in technology enhancements and has also experienced inflation-driven price increases.
Busey’s efficiency ratio(2) was 58.5% for the third quarter of 2025, compared to 63.9% for the second quarter of 2025 and 61.8% for the third quarter of 2024. Our adjusted efficiency(2) ratio was 54.8% for the third quarter of 2025, compared to 55.3% for the second quarter of 2025, and 60.2% for the third quarter of 2024. As our business grows, Busey remains focused on prudently managing our expense base and operating efficiently.

___________________________________________
1. Amounts reported as provision for loan losses for periods ending prior to June 30, 2025, were previously reported as provision for credit losses. The nine months ended September 30, 2025, included $42.4 million to establish an initial allowance for loan losses for loans purchased without credit deterioration (“non-PCD” loans) following the close of the CrossFirst acquisition.
2. The three months ended June 30, 2025, included a $4.0 million adjustment to the initial provision for unfunded commitments resulting from the adoption of a new CECL model. Including the adjustment recorded in the second quarter, the nine months ended September 30, 2025, included a total of $7.2 million to establish an initial allowance for unfunded commitments following the close of the CrossFirst acquisition.
3. 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.
Net charge-offs decreased by $7.0 million when compared to the second quarter of 2025, and increased by $5.6 million when compared with the third quarter of 2024. Net charge-offs during the nine months ended September 30, 2025, included $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.
The $3.3 million provision reversal for loan losses recorded in the third quarter of 2025 included a provision release of $7.1 million for PCD loans due to payoffs/paydowns and a provision expense of $3.8 million for non-PCD loans to support charge-offs and qualitative factor adjustments.
Deposits
Busey’s deposits were comprised of the following:

|  | As of

Noninterest-bearing deposits |  | $ | 3,554,936 |  |  | $ | 3,590,363 |  |  |  |  |  |  | $ | 2,683,543 |
Interest-bearing transaction deposits |  | 3,171,255 |  |  | 3,216,601 |  |  |  |  |  |  | 2,455,217 |

Total deposits |  | $ | 15,070,162 |  |  | $ | 15,801,772 |  |  |  |  |  |  | $ | 9,943,241 |

In the third quarter of 2025, Busey executed a strategic targeted reduction of high-cost, non-relationship deposits, resulting in the intentional runoff of $794.6 million of deposits, including $228.2 million of brokered deposits, bearing a weighted average cost of 4.45%. Excluding this targeted runoff, deposits grew by $63.0 million during the third quarter of 2025.
Core deposits(2) accounted for 93.8% of total deposits as of September 30, 2025. The quality of our core deposit franchise is a critical value driver of our institution. We estimated that 35% of our deposits were uninsured and uncollateralized(5) as of September 30, 2025, and we have ample on- and off-balance sheet liquidity to manage deposit fluctuations and the liquidity needs of our customers.
We have executed various deposit campaigns to attract term funding and savings accounts at a lower rate than our marginal cost of funds. New certificate of deposit production in the third quarter of 2025 had a weighted average term of 7.6 months at a rate of 3.79%, which was 50 basis points below our average marginal wholesale equivalent-term funding cost during the quarter.

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 Merchants and Manufacturers Bank Corporation. The redemption of the Subordinated Note is subject to and conditioned upon regulatory approval from the Board of Governors of the Federal Reserve System. Assuming the requisite approvals are retained, the Subordinated Note will be redeemed on its optional redemption date of December 4, 2025.
Liquidity
As of September 30, 2025, Busey’s available sources of on- and off-balance sheet liquidity(6) totaled $7.85 billion. Furthermore, Busey’s balance sheet liquidity profile continues to be aided by the cash flows expected from Busey’s relatively short-duration securities portfolio. Those cash flows were approximately $170.3 million in the third quarter of 2025. Cash flows from maturing securities within our portfolio are expected to be approximately $90.5 million for the fourth quarter of 2025, with a current book yield of 2.53%, and approximately $305.9 million for 2026, with a current book yield of 2.66%.
Capital Strength
The strength of our balance sheet is also reflected in our capital foundation. Our capital ratios remain strong, and as of September 30, 2025, our estimated regulatory capital ratios(3) continued to provide a buffer of more than $810 million above levels required in order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments. The following table presents Busey’s capital estimates(3) and tangible equity position:

This earnings release contains certain financial information determined by methods other than GAAP. Management uses these non-GAAP measures, together with the related GAAP measures, in analysis of Busey’s performance and in making business decisions, as well as for comparison to 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 items and provide additional perspective on Busey’s performance over time.
The following tables present reconciliations between these non-GAAP measures and what management believes to be the most directly comparable GAAP financial measures.
These non-GAAP disclosures have inherent limitations and are not audited. They should not be considered in isolation or as a substitute for operating results reported in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Tax effected numbers included in these non-GAAP disclosures are based on estimated statutory rates, estimated federal income tax rates, or effective tax rates, as noted with the tables below.

___________________________________________
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.
6. Annualized measure.

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 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.
