MESSAGE FROM OUR CHAIRMAN, PRESIDENT, & CEO	CONTENTS
Our results this quarter represent a meaningful culmination to a year of strong performance and the completed merger and integration of CrossFirst. Profitability in the fourth quarter showed vast improvement from last year with adjusted return on average assets2 improving 39 basis points to 1.41% and net interest margin2 expanding 76 basis points to 3.71%, driven by continued strong deposit cost control. Wealth management fee income had a record quarter as assets under care were up 4.7% quarter-over-quarter to $15.66 billion driven by strong investment performance and positive net flows from new and legacy markets. Capital remained strong, and Common Equity Tier 1 Capital to Risk Weighted Assets3 grew to 12.44%, a 11 basis point increase from the prior quarter. Tangible common equity to tangible assets2 grew to 10.06% with tangible book value per common share2 increasing 13.1% over the prior year end, even as we repurchased $29.8 million of stock in the fourth quarter and $69.9 million for the full year. Loan balances were stable quarter-over-quarter and deposits were down $164.2 million due to the intentional runoff of $180.0 million as Busey continued its strategic, targeted reduction of brokered and high-cost, non-relationship funding. As we look forward to 2026, Busey is well positioned to navigate diverse macroeconomic scenarios given its robust capital and liquidity position and disciplined credit and risk management culture.

FINANCIAL RESULTS

Fourth quarter 2025 net income for First Busey Corporation, together with its consolidated subsidiaries (“Busey,” the “Company,” “we,” “us,”, or “our”) was $60.8 million, or $0.63 per diluted common share, compared to $57.1 million, or $0.58 per diluted common share, for the third quarter of 2025, and $28.1 million, or $0.49 per diluted common share, for the fourth quarter of 2024. Annualized return on average assets2 and annualized return on average tangible common equity2 were 1.32% and 12.59%, respectively, for the fourth quarter of 2025. Total noninterest expense and adjusted noninterest expense were impacted by a $3.8 million operating loss tied to one relationship.

Taking into account our fourth quarter results, full year 2025 net income was $135.3 million, or $1.47 per diluted common share. Return on average assets and return on average tangible common equity2 were 0.76% and 7.48%, respectively.

___________________________________________

(i)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.

Dividends on preferred stock decreased in the fourth quarter of 2025 compared to the third quarter of 2025. 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. The first dividend on the Series B Preferred Stock 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 of 2025.

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:

Net interest income increased by $2.4 million in the fourth quarter of 2025, compared to the third quarter of 2025, primarily due to applying measured rate cutting initiatives to optimize funding costs. Deposit funding cost reduction during the quarter of 24 basis points represents a 53% beta relative to the quarterly move in the fed funds target average rate.

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 1.8% (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 at quarter-end. Continued targeted reduction of $180.0 million deposits bearing a weighted average cost of 4.16% included $55.0 million of brokered deposits. At December 31, 2025, Busey Bank had $70.1 million of remaining brokered funding, comprising 0.5% of total deposits. Total deposit cost of funds decreased from 2.15% during the third quarter of 2025 to 1.91% during the fourth quarter of 2025. At December 31, 2025, our spot rate on total deposits costs was 1.80%, compared to 2.01% at September 30, 2025.

Total noninterest income increased by 3.6% compared to the third quarter of 2025 primarily due to increases in wealth management fees and other noninterest income. Compared to the fourth quarter of 2024, total noninterest income increased by 21.2% as we benefit from the CrossFirst Bankshares, Inc. (“CrossFirst”) acquisition and extend services into new markets. For the full year 2025, total noninterest income increased by 7.4%.

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 66.9% of noninterest income excluding net securities gains and losses2 for the fourth quarter of 2025 and 69.3% for the full year.

Noteworthy changes in noninterest income during the quarter include:

•Wealth management fees increased by $0.9 million, or 5.3%, compared to the third quarter of 2025 primarily due to increases in trust fees and farm management fees. Busey’s Wealth Management division ended the fourth quarter of 2025 with $15.66 billion in assets under care, compared to $14.96 billion at the end of the third quarter of 2025 and $13.83 billion at the end of the fourth 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 benchmark4 over the last three and five years.

•Other noninterest income increased by $0.9 million, or 14.7%, compared to the third quarter of 2025, primarily due to increased swap origination fee and loan fee income, partially offset by fluctuations in gains on private equity investments.

Total noninterest expense increased by 0.3% compared to the third quarter of 2025, primarily due to increases in other noninterest expense. Compared to the fourth quarter of 2024 total noninterest expense increased by 53.0%, with the increases 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 with 100% realization of identified synergies in 2026.

Adjusted noninterest expense,2 which excludes acquisition and restructuring expenses and amortization of intangible assets, was as follows:

Adjusted noninterest expense (Non-GAAP)	$	111,072	$	108,304	$	72,566	$	408,938	$	283,297

Noteworthy changes in noninterest expense during the quarter include:

•Salaries, wages, and employee benefits expenses declined by $5.2 million, or 6.9%, compared to the third quarter of 2025, with acquisition and restructuring expenses declining by $1.6 million. Compared to the fourth quarter of 2024, salaries, wages, and employee benefits expenses increased by $23.5 million, or 51.8%, of which $3.8 million was attributable to increases in acquisition and restructuring expenses. During 2025, Busey added 17 banking centers, largely in connection with the CrossFirst acquisition, resulting in the expansion of Busey’s workforce, including the addition of 405 full-time equivalent associates.

First Busey Corporation (BUSE) | 2025 Q4 — 8

•Other noninterest expense increased by $5.5 million, or 38.8%, compared to the third quarter of 2025, and increased by $9.5 million, or 93.6%, compared to the fourth quarter of 2024. Significant drivers of the increase included a $3.8 million operating loss recognized in the fourth quarter of 2025 tied to one relationship, loan expenses, and marketing and business development costs.

Busey’s efficiency ratio2 was 57.4% for the fourth quarter of 2025, compared to 58.5% for the third quarter of 2025 and 64.8% for the fourth quarter of 2024. The adjusted efficiency2 ratio was 55.0% for the fourth quarter of 2025, compared to 54.8% for the third quarter of 2025, and 61.8% for the fourth quarter of 2024. As our business grows, Busey remains focused on prudently managing our expense base and operating efficiently.

Taxes

Busey's effective tax rate for the fourth quarter of 2025 declined to 21.6% compared to 26.1% for the third quarter. The decrease compared with the prior period resulted primarily from the utilization of purchased federal income tax credits and more favorable state apportionment outcomes. For the full year 2025, Busey’s effective tax rate was 27.5%.

BALANCE SHEET STRENGTH

Busey’s financial strength is built on a long-term conservative operating approach. That focus has endured over time and will continue to guide us in the future.

Non-performing assets increased by $0.4 million compared to September 30, 2025, and increased by $34.8 million compared to December 31, 2024, with the increase compared to the prior year due primarily to the loans purchased with credit deterioration (“PCD”) assumed in the CrossFirst acquisition. Non-performing assets represented 0.32% of total assets as of both December 31, 2025, and September 30, 2025, a 13 basis point increase from December 31, 2024.

Classified assets increased by $13.5 million compared to September 30, 2025, and increased by $89.2 million compared to December 31, 2024, with the increase compared to the prior year due primarily to the PCD loans assumed in the CrossFirst acquisition.

The allowance for credit losses was $174.0 million as of December 31, 2025, 3.25 times our non-performing loans balance and representing 1.28% of total portfolio loans outstanding.

First Busey Corporation (BUSE) | 2025 Q4 — 11

Busey’s net charge-offs and provision for credit losses were as follows:




	Three Months Ended						Years Ended
(dollars in thousands)	December 31, 2025		September 30, 2025		December 31, 2024		December 31, 2025		December 31, 2024
Net charge-offs	$	5,752	$	5,848	$	2,850	$	55,910	$	18,169

Provision for loan losses(i)	$	5,594	$	(3,305)	$	1,273	$	45,746	$	8,590

Provision for credit losses(iii)	$	2,435	$	(985)	$	818	$	52,743	$	7,495

___________________________________________

(i)Amounts reported as provision for loan losses for periods ending prior to June 30, 2025, were previously reported as provision for credit losses. The year ended December 31, 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.

(ii)The year ended December 31, 2025, included a total of $7.2 million to establish an initial allowance for unfunded commitments following the close of the CrossFirst acquisition and adoption of a new CECL model.

(iii)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 $0.1 million when compared to the third quarter of 2025, and increased by $2.9 million when compared with the fourth quarter of 2024. Net charge-offs during the year ended December 31, 2025, included $36.2 million related to PCD loans assumed in the CrossFirst acquisition.

Provision expense recorded in the fourth quarter of 2025 included $4.5 million for PCD loans, driven by specific allocations/individual reserves.

Deposits

Busey’s deposits were comprised of the following:


	As of
(dollars in thousands)	December 31, 2025		September 30, 2025		December 31, 2024
DEPOSITS
Noninterest-bearing deposits	$	3,659,421	$	3,554,936	$	2,719,907
Interest-bearing transaction deposits	3,119,475		3,171,255		2,423,237
Savings deposits and money market deposits	5,697,172		5,910,183		3,348,711
Time deposits	2,429,890		2,433,788		1,490,635
Total deposits	$	14,905,958	$	15,070,162	$	9,982,490

In the fourth quarter of 2025, Busey continued executing on its strategic targeted reduction of high-cost, non-relationship deposits, resulting in the intentional runoff of $180.0 million of deposits, including $55.0 million of brokered deposits and $125.0 million of corporate deposits, bearing a weighted average cost of 4.16%. Excluding this targeted runoff, deposits grew by $15.8 million during the fourth quarter of 2025 despite seasonal outflows of $242.4 million of public funds, which we expect to recover through seasonal inflows of public funds in the second and third quarters of 2026.

Core deposits2 accounted for 93.7% of total deposits as of December 31, 2025. The quality of our core deposit franchise is a critical value driver of our institution. We estimated that 37% of our deposits were uninsured and uncollateralized5 as of December 31, 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 fourth quarter of 2025 had a weighted average term of 6.6 months at a rate of 3.64%, which was 27 basis points below our average marginal wholesale equivalent-term funding cost during the quarter.

First Busey Corporation (BUSE) | 2025 Q4 — 12

Liquidity

As of December 31, 2025, Busey’s available sources of on- and off-balance sheet liquidity6 totaled $7.68 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 $150.0 million in the fourth quarter of 2025. Cash flows from our securities portfolio are expected to be approximately $347.1 million for 2026, with a current book yield of 2.92%.

Capital Strength

The strength of our balance sheet is also reflected in our capital foundation. Our capital ratios remain strong, and as of December 31, 2025, our estimated regulatory capital ratios3 continued to provide a buffer of more than $830 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 estimates3 and tangible equity position:


	As of
(dollars in thousands, except per share amounts)	December 31, 2025			September 30, 2025			December 31, 2024
Common equity Tier 1 capital to risk weighted assets(i)	12.44		%	12.33		%	14.10		%

Dividends

Busey's strong capital levels, coupled with its earnings, have allowed the Company to provide a steady return to its stockholders through dividends. During the fourth quarter of 2025, Busey paid dividends of $0.25 per share on its outstanding shares of common stock, $20.00 per share on its outstanding shares of Series A Non-Cumulative Perpetual Preferred Stock, which was issued in connection with the CrossFirst acquisition, and $0.515625 per outstanding depositary share, each representing a 1/40th interest in a share of Busey’s 8.25% Fixed-Rate Series B Non-Cumulative Perpetual Preferred Stock.

On January 30, 2026, Busey will pay a cash dividend of $0.26 per common share outstanding to stockholders of record as of January 23, 2026, which represents a 4% increase from the previous quarterly dividend of $0.25 per share. Busey has consistently paid dividends to its common stockholders since the bank holding company was organized in 1980.

Share Repurchases

During the fourth quarter of 2025, under its stock repurchase plan, Busey purchased 1,251,100 shares of its common stock at a weighted average price of $23.84 per share for a total of $29.8 million. For the full year 2025, Busey purchased 3,063,100 shares of its common stock at a weighted average price of $22.81 per share for a total of $69.9 million.

___________________________________________

(i)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.

(ii)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.

(iii)Tax benefits were calculated for the year-to-date periods using tax rates of 26.28% and 24.88% for the years ended December 31, 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.

(iv)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.

(v)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.

(vi)For quarterly periods, measures are annualized.

FORWARD-LOOKING STATEMENTS

This press release 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 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, military conflicts, acts of war or threats thereof, or other adverse external events that could cause economic deterioration or instability in credit markets (including Russia’s invasion of Ukraine, the conflicts in the Middle East, and recent military activity in Venezuela); (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.
