Market Competition
Busey Bank competes actively with national and state banks, savings and loan associations, and credit unions for deposits and loans mainly in Illinois; the St. Louis, Missouri, metropolitan area; southwest Florida; and central Indiana. Busey Bank competes for real estate and other loans primarily on the basis of type of loan, interest rates and loan fees, and the quality of services provided. Busey Bank and FirsTech compete with other financial institutions, including asset management and trust companies, security broker/dealers, personal loan companies, insurance companies, finance companies, leasing companies, mortgage companies, payment technology solution companies, financial technology companies, and certain governmental agencies, all of which actively engage in marketing various types of loans, deposit accounts, wealth management, and other products and services.
Busey Bank faces substantial competition in attracting deposits from other commercial banks, savings institutions, digital banks, money market and mutual funds, credit unions, insurance agencies, brokerage firms, and other investment vehicles. Customers for banking services are generally influenced by convenience, quality of service, personal contacts, price of services, and availability of products. Busey Bank attracts a significant amount of deposits through its banking centers, primarily from the communities in which those banking centers are located; therefore, competition for those deposits is principally from other commercial banks, savings institutions, and credit unions located in the same communities. Busey Bank competes for deposits by offering a variety of deposit accounts at competitive rates, high-quality customer service, convenient business hours, technology enabled solutions including internet and mobile banking, and convenient banking centers with inter-branch deposit and withdrawal privileges.
Based on information obtained from the FDIC Summary of Deposits dated June 30, 2024, the most recent report available, out of 355 financial institutions headquartered in the State of Illinois, Busey Bank ranked fourth in total deposits within the Illinois market. Further, Busey Bank ranked in the top 10 in total deposits in nine Illinois counties:

HUMAN CAPITAL
Busey is built upon a strong commitment to associate, customer, stockholder, and community, with its associates as the cornerstone of this unwavering commitment. Busey’s vision, Service Excellence in Everything We Do, starts with Busey’s dedication to its associates. Busey is deeply humbled to be consistently recognized nationally and locally throughout the Company’s footprint, including being named nationally among the World’s Best Banks and America’s Best Banks by Forbes; the Best Banks to Work For by American Banker; and the Best Places to Work in Money Management by Pension and Investments. Locally, Busey was once again voted among the Best Places to Work in Illinois and a Best Company to Work For in Florida. From exceeding the needs of customers and colleagues to serving their communities selflessly, Busey associates show unmatched dedication to the Company. Their shared experiences are what make these and other awards possible. Since Busey opened its doors 157 years ago, Busey has maintained its core values, creating a strong foundation and shaping its inclusive culture.

Table of Contents Contents of Item 1. Business
Busey remains committed to fostering a welcoming and supportive environment within its organization, the banking profession, and the communities in which it operates. Busey is dedicated to attracting and retaining talent across a variety of backgrounds and experiences. Teams with varying beliefs and opinions promote productivity, creativity, and innovation, while better meeting and exceeding the needs of Busey’s customer base. Recruiting, supporting, and retaining a workforce with varying perspectives and ideas, while maintaining a welcoming culture, is the foundation of Busey’s core values—One Busey. Busey’s endeavors in this regard are reported to the Employee Benefit and Compensation Committee and to the Board's Enterprise Risk Committee, which hold the organization accountable to this core value at the highest levels of management.
Associate engagement is an important barometer of Busey’s cultural health. Busey regularly solicits feedback to understand the views of its associates about their work environment and Busey’s culture. The results from engagement surveys are used to implement programs and processes designed to enhance engagement and improve the associate experience. With a strong 91% participation rate and an approach focused on continuous improvement, 2024 results increased to the highest scores in Busey’s history. One such way to keep associates informed and engaged is through quarterly update calls, which are conducted by Busey leadership. These calls provide important information about the financial health of the Company, but more importantly they provide a cultural touchpoint to solidify Busey’s commitment to its number one asset – its associates. A tenet of Busey’s engaged culture is a commitment to investing in associates through unique, award-winning training and development programs. In 2024, 59% of Busey’s associate base engaged in talent and leadership development programs. Since 2017, Busey has been a proud recipient of the Association for Talent Development’s BEST Award, which is presented to organizations that demonstrate enterprise-wide success as a result of employee talent development.
Additionally, Busey cares about the health and well-being of its associates and their families, as evidenced by a strong investment and an 85% participation rate in Busey’s innovative, holistic health and wellness program, B Well. Investments in B Well include a stress management and mental wellness component, lifesaving biometric screenings, a corporate health and wellness coach, onsite wellness center, health club reimbursements, on-demand wellness streaming service and Health Savings Account investments funded by the Company. In 2024, Busey was honored to be recognized among the Illinois' Healthiest Employers by global health insurer Cigna and Crain’s Content Studio, marking the seventh year the Company was named among this elite group.

SUPERVISION, REGULATION, AND OTHER FACTORS
General
FDIC-insured institutions, like Busey Bank, as well as their holding companies and affiliates, are extensively regulated under federal and state law. As a result, Busey’s growth and earnings performance may be affected not only by management decisions, competitive dynamics, and general economic conditions, but also by the requirements of federal and state statutes and by the regulations and policies of various banking agencies, including the DFPR, the Federal Reserve, the FDIC and the CFPB. Furthermore, taxation laws administered by the Internal Revenue Service and state taxing authorities, accounting rules developed by the FASB, securities laws administered by the SEC and state securities authorities, and anti-money laundering laws and sanctions enforced by the U.S. Treasury have an impact on Busey’s business. The effect of these statutes, regulations, regulatory policies, and accounting rules are significant to Busey’s operations and results.
Federal and state banking laws impose a comprehensive system of supervision, regulation, and enforcement on the operations of FDIC-insured institutions, their holding companies, and affiliates that is intended primarily for the protection of the FDIC-insured deposits and depositors of banks, rather than stockholders. These laws, and the regulations of the banking agencies issued under them, affect, among other things, the scope of Busey’s business; the kinds and amounts of investments that Busey and Busey Bank may make; required capital levels relative to assets; the nature and amount of collateral for loans; the establishment of branches; the ability of Busey and Busey Bank to merge, consolidate and acquire; dealings with Busey’s and Busey Bank’s insiders and affiliates; and Busey’s payment of dividends.
In reaction to the global financial crisis and particularly following the passage of the Dodd-Frank Act in 2010, Busey experienced heightened regulatory requirements and scrutiny. Although the reforms primarily targeted large banking organizations and systemically important financial institutions (at the time, those with assets of $50 billion and greater), certain provisions of the law triggered at $10 billion in assets and the influence of other provisions filtered down in varying degrees to community banks over time, causing Busey’s compliance and risk management processes, and the costs thereof, to increase. The Regulatory Relief Act provided meaningful relief for banks and their holding companies that were not considered systemically important (amended to be those with assets under $250 billion). However, the $10 billion threshold remained in place for certain Dodd-Frank Act reforms that are applicable to Busey, as discussed below. It is anticipated that the current presidential administration and the current U.S. Congress likely will not increase the regulatory burden on banking organizations. At this time, however, it is not possible to predict with any certainty the actual impact that the current political climate may have on the banking industry or the operations of Busey or Busey Bank.

Table of Contents Contents of Item 1. Business
The supervisory framework for U.S. banking organizations subjects banks and bank holding companies to regular examination by their respective banking agencies, which results in examination reports and ratings that are not publicly available and that can impact the conduct and growth of their businesses. These examinations consider not only compliance with applicable laws and regulations, but also capital levels, asset quality and risk, management ability and performance, earnings, liquidity, and various other factors. The regulatory agencies generally have broad discretion to impose restrictions and limitations on the operations of a regulated entity where the agencies determine, among other things, that such operations are unsafe or unsound, fail to comply with applicable law, or are otherwise inconsistent with laws and regulations. The approach to supervision adopted by each banking agency may have significant impacts on the operations and results of Busey and Busey Bank, as well as the banking industry in general. Based on statements made by congressional leaders and the acting leaders of certain federal banking agencies, there may be changes in the supervisory processes and approach made by the banking agencies, but it is not possible at this time to predict the specific changes (or the timing of any such changes) that may be made.
The following is a summary of the material elements of the supervisory and regulatory framework applicable to First Busey and Busey Bank. It does not describe all of the statutes, regulations, and regulatory policies that apply, nor does it restate all of the requirements of those that are described. The descriptions are qualified in their entirety by reference to particular statutory and regulatory provisions.
The $10 billion Threshold
As indicated above, the Dodd-Frank Act included a number of requirements that were triggered when a banking entity crossed over $10 billion in assets. Those included requirements for stress testing capital, maintenance of a risk committee, adherence to the Volcker Rule’s complicated prohibitions on proprietary trading and ownership of private funds, limitations on interchange fees for certain debit transactions, clearing of swap agreements, and examination and enforcement related to consumer financial services by the CFPB, in addition to a number of heightened reporting requirements. The Regulatory Relief Act eliminated the stress test and risk committee requirements for banking entities between $10 billion and $50 billion, but the other regulations and reporting requirements under the Dodd-Frank Act were not changed.
Busey crossed the $10 billion threshold in 2020. The material consequences to Busey of crossing the $10 billion threshold are as follows:
Interchange Fees
The Durbin Amendment to the Dodd-Frank Act required the Federal Reserve to establish a maximum permissible interchange fee for many types of debit transactions. Interchange fees, also known as “swipe” fees, are charges that merchants pay to card-issuing banks, such as Busey Bank, for processing electronic payment transactions. The Federal Reserve set the maximum interchange fee at 21 cents, plus five bps of the transaction value. The Federal Reserve also adopted a rule to allow a debit card issuer to recover one cent per transaction for fraud prevention purposes if the issuer complies with certain fraud-related requirements required by the Federal Reserve. Fee limits imposed by the Durbin Amendment are applicable to any banking organization with over $10 billion in assets and became applicable to Busey Bank on July 1, 2022, following a six-month transition period. Compliance with the Durbin Amendment has reduced Busey Bank’s earnings on the covered debit transactions.

Table of Contents Contents of Item 1. Business
Volcker Rule
The Volcker Rule (also a part of the Dodd-Frank Act) restricts the ability of banking organizations (holding companies and their affiliates) with over $10 billion in assets to sponsor or invest in private funds, or to engage in certain types of proprietary trading. In October 2019, the Federal Reserve, OCC, FDIC, Commodity Futures Trading Commission, and SEC finalized rules to tailor the application of the Volcker Rule based on the size and scope of a banking organization’s trading activities and to clarify and amend certain definitions, requirements, and exemptions. Banking organizations have two years (with a possibility of extensions) to comply with the Volcker requirements after crossing the $10 billion threshold. Busey does not materially engage in the activities prohibited by the Volcker Rule; therefore, the application of the rule will not have a material effect on Busey’s operations.
CFPB Examination and Enforcement
Although most of the CFPB’s rules issued under federal consumer financial protection laws are applicable to all providers of consumer financial services, the CFPB only has examination and enforcement authority over banks with more than $10 billion in assets (measured over four consecutive quarters). Busey Bank is under CFPB oversight for consumer banking transactions and continues to be examined for compliance with consumer laws by its primary federal regulator, the Federal Reserve.
Clearing Swaps Agreements
Banks with over $10 billion in assets are required to clear swaps agreements on exchanges. Busey Bank began to comply with the exchange requirement beginning in 2021.
Risk Committee
The Dodd-Frank Act required publicly traded bank holding companies with more than $10 billion in total consolidated assets to establish and maintain a risk committee. Pursuant to the Federal Reserve’s final rules issued under the Regulatory Relief Act, that threshold was increased to $50 billion. Although it is not yet required to have a risk committee in place, Busey established a committee comprised of holding company directors in 2018 to oversee risk matters in preparation for future growth.
The Role of Capital
Regulatory capital represents the net assets of a banking organization available to absorb losses. Because of the risks attendant to their business, FDIC-insured institutions, such as Busey Bank, as well as their holding companies (i.e., banking organizations), generally are required to hold more capital than other businesses. These requirements directly affect Busey’s earnings capabilities. Although capital historically has been one of the key measures of the financial health of both bank holding companies and banks, its role became fundamentally more important in the wake of the global financial crisis, as the banking regulators recognized that the amount and quality of capital held by banking organizations prior to that crisis was insufficient to absorb losses during periods of severe stress.
First Busey Corporation (BUSE) | 2024 — 13

Table of Contents Contents of Item 1. Business
Capital Levels
Banking organizations have been required to hold minimum levels of capital based on guidelines established by the banking agencies since 1983. The minimum capital levels for banking organizations have been expressed in terms of ratios of “capital” divided by “total assets.” Beginning in 1989, capital guidelines for U.S. banking organizations have been based upon international capital accords, known as “Basel” accords, adopted by the Basel Committee on Banking Supervision, a committee of central banks and bank supervisors that acts as the primary global standard-setter for prudential regulation, as implemented by the U.S. federal banking agencies on an interagency basis. These accords recognized that bank assets for the purpose of the capital ratio calculations needed to be risk weighted (the theory being that riskier assets should require more capital) and that off-balance sheet exposures needed to be factored into the calculations. Following the global financial crisis, the Group of Governors and Heads of Supervision, the oversight body of the Basel Committee on Banking Supervision, announced an agreement on a strengthened set of capital requirements for banking organizations around the world, known as the Basel III accords, to address deficiencies recognized in connection with the global financial crisis.
The Basel III Rule
U.S. federal banking agencies adopted the Basel III Rule in regulations that were effective (with a number of phase-ins) in 2015. The Basel III Rule established capital standards for banks and bank holding companies that are meaningfully more stringent than those established previously and are still in effect today. The Basel III Rule is applicable to all banking organizations that are subject to minimum capital requirements, including national banks, state banks, and savings and loan associations, as well as to most bank and savings and loan holding companies. First Busey and Busey Bank are each subject to the Basel III Rule as described below.
Risk-Weighting Assets
Three of the required Basel III capital ratios, as discussed immediately below, are calculated using a denominator of total “risk-weighted” assets. In the calculation of so-called “risk weights,” which was introduced in the first Basel accord, bank assets were divided into four basic risk-weighted categories of zero, 20, 50, and 100%. Basel III required a more complex, detailed and calibrated assessment of risk in the calculation of risk weightings. Although it uses the same technique introduced by the Basel I accord in assigning assets to risk-weight categories, it significantly increases the number of categories and adds conditions to the assignment of certain risk weights. Risk weights were established as high as 250% for certain CRE exposures, and higher for certain derivatives.
The assignment of risk weights is likely to continue to be under review by federal banking agencies as they seek to implement certain remaining elements of Basel III. In July 2023, the Biden Administration banking agencies had proposed wide-ranging and significant changes to the Basel III Rules (the “Basel III Endgame Proposal”), which would have, among other requirements, imposed structural changes to the calculation of capital requirements and risk-weighted assets. The Basel III Endgame Proposal would generally have impacted the capital requirements applicable to banking organizations with $100 billion or more in total assets and, as a general matter, would not impact Busey. The Basel III Endgame Proposal has not been, and is not expected to be, adopted in a form substantially similar to the Basel III Endgame Proposal. The banking agencies may issue their own version of this proposal.

Minimum Capital Ratio Requirements
The Basel III Rule also increased the required quantity and quality of capital. Not only did it increase most of the required minimum capital ratios in effect prior to January 1, 2015, but in requiring that forms of capital be of higher quality to absorb loss, it also introduced the concept of Common Equity Tier 1 Capital, which consists primarily of common stock, related surplus (net of Treasury stock), retained earnings, and Common Equity Tier 1 minority interests subject to certain regulatory adjustments. The Basel III Rule also changed the definition of capital by establishing more stringent criteria that instruments must meet to be considered Additional Tier 1 Capital (primarily non-cumulative perpetual preferred stock that meets certain requirements) and Tier 2 Capital (primarily other types of preferred stock and subordinated debt, subject to limitations). The Basel III Rule also constrained the inclusion of minority interests, mortgage-servicing assets, and deferred tax assets in capital and required deductions from Common Equity Tier 1 Capital if such assets exceeded a percentage of a banking organization’s Common Equity Tier 1 Capital.
The Basel III Rule requires banking organizations to maintain minimum capital ratios as follows:
•A ratio of Common Equity Tier 1 Capital equal to 4.5% of risk-weighted assets;
•A ratio of Tier 1 Capital equal to 6% of risk-weighted assets;
•A continuation of the minimum required amount of Total Capital (Tier 1 plus Tier 2) at 8% of risk-weighted assets; and
•A leverage ratio of Tier 1 Capital to total quarterly average assets equal to 4% in all circumstances.
Capital Conservation Buffer
In addition, banking organizations that want to make capital distributions (including for dividends and repurchases of stock) and pay discretionary bonuses to executive officers without restriction also must maintain 2.5% in Common Equity Tier 1 Capital attributable to a capital conservation buffer. The purpose of the conservation buffer is to ensure that banking institutions maintain a buffer of capital that can be used to absorb losses during periods of financial and economic stress. Factoring in the conservation buffer increases the minimum ratios depicted above to 7% for Common Equity Tier 1 Capital, 8.5% for Tier 1 Capital and 10.5% for Total Capital.
Well-Capitalized Requirements
The ratios described above are minimum standards for banking organizations to be considered “adequately capitalized.” Banking agencies uniformly encourage banking organizations to hold more capital and be “well-capitalized” and, to that end, federal law and regulations provide various incentives for banking organizations to maintain regulatory capital at levels in excess of minimum regulatory requirements. For example, a banking organization that is well-capitalized may: (1) qualify for exemptions from prior notice or application requirements otherwise applicable to certain types of activities; (2) qualify for expedited processing of other required notices or applications; and (3) accept, roll-over or renew brokered deposits. Higher capital levels also could be required if warranted by the particular circumstances or risk profiles of individual banking organizations. For example, the Federal Reserve’s capital guidelines contemplate that additional capital may be required to take adequate account of, among other things, interest rate risk or the risks posed by concentrations of credit, nontraditional activities, or securities trading activities. Further, any banking organization experiencing or anticipating significant growth would be expected to maintain capital ratios, including tangible capital positions (i.e., Tier 1 Capital less all intangible assets), well above the minimum levels.
Under the capital regulations of the Federal Reserve, in order to be well-capitalized, a banking organization must maintain all of the following:
•A Common Equity Tier 1 Capital ratio to risk-weighted assets of 6.5% or more;
First Busey Corporation (BUSE) | 2024 — 15

Table of Contents Contents of Item 1. Business
•A ratio of Tier 1 Capital to total risk-weighted assets of 8% or more;
•A ratio of Total Capital to total risk-weighted assets of 10% or more; and
•A leverage ratio of Tier 1 Capital to total adjusted average quarterly assets of 5% or greater.
It is possible under the Basel III Rule to be well-capitalized while remaining out of compliance with the capital conservation buffer discussed above.
As of December 31, 2024: (1) Busey Bank was not subject to a directive from the Federal Reserve or the DFPR to increase its capital, and (2) Busey Bank was well-capitalized, as defined by Federal Reserve regulations. As of December 31, 2024, Busey had regulatory capital in excess of the Federal Reserve’s requirements and met the Basel III Rule requirements to be well-capitalized. First Busey also is in compliance with the capital conservation buffer.
Prompt Corrective Action
The concept of a banking organization being “well-capitalized” is part of a regulatory enforcement regime that provides the federal banking agencies with broad power to take “prompt corrective action” to resolve the problems of depository institutions based on the capital level of each particular institution. The extent of the regulators’ powers depends on whether the banking organization in question is “adequately capitalized,” “undercapitalized,” “significantly undercapitalized” or “critically undercapitalized,” in each case as defined by regulation. Depending upon the capital category to which a banking organization is assigned, the banking agencies’ corrective powers include: (1) requiring the institution to submit a capital restoration plan; (2) limiting the institution’s asset growth and restricting its activities; (3) requiring the institution to issue additional capital stock (including additional voting stock) or to sell itself; (4) restricting transactions between the institution and its affiliates; (5) restricting the interest rate that the institution may pay on deposits; (6) ordering a new election of directors of the institution; (7) requiring that senior executive officers or directors be dismissed; (8) prohibiting the institution from accepting deposits from correspondent banks; (9) requiring the institution to divest certain subsidiaries; (10) prohibiting the payment of principal or interest on subordinated debt; and (11) ultimately, appointing a receiver for the institution.
Supervision and Regulation of First Busey Corporation
General
First Busey Corporation, as the sole stockholder of Busey Bank, is a bank holding company. As a bank holding company, First Busey Corporation is registered with, and subject to regulation, supervision, and enforcement by, the Federal Reserve under the BHCA. First Busey Corporation is legally obligated to act as a source of financial and managerial strength to Busey Bank and to commit resources to support it in circumstances where First Busey Corporation might not otherwise do so. Under the BHCA, First Busey Corporation is subject to periodic examination by the Federal Reserve and is required to file with the Federal Reserve periodic reports of its operations and such additional information regarding First Busey Corporation and Busey Bank as the Federal Reserve may require.

Table of Contents Contents of Item 1. Business
Acquisitions, Activities and Financial Holding Company Election
The primary purpose of a bank holding company is to control and manage banks. The BHCA generally requires the prior approval of the Federal Reserve for any merger involving a bank holding company or any acquisition by a bank holding company of another bank or bank holding company. Subject to certain conditions (including deposit concentration limits established by the BHCA), the Federal Reserve may allow a bank holding company to acquire banks located in any state of the United States. In approving interstate acquisitions, the Federal Reserve is required to give effect to applicable state law limitations on the aggregate amount of deposits that may be held by the acquiring bank holding company and its FDIC-insured institution affiliates in the state in which the target bank is located (provided that those limits do not discriminate against out-of-state institutions or their holding companies) and state laws that require that the target bank have been in existence for a minimum period of time (not to exceed five years) before being acquired by an out-of-state bank holding company. Furthermore, in accordance with the Dodd-Frank Act, bank holding companies must be well-capitalized and well-managed in order to effect interstate mergers or acquisitions. For a discussion of the capital requirements, see “Item 1. Business—Supervision, Regulation and Other Factors—The Role of Capital” above.
The BHCA generally prohibits bank holding companies from acquiring direct or indirect ownership or control of more than 5% of the voting shares of any company that is not a bank and from engaging in any business other than that of banking, managing, and controlling banks, or furnishing services to banks and their subsidiaries. This general prohibition is subject to a number of exceptions. The principal exception allows bank holding companies to engage in, and to own shares of companies engaged in, certain businesses found by the Federal Reserve prior to November 11, 1999, to be “so closely related to banking ... as to be a proper incident thereto.” This authority permits First Busey Corporation to engage in a variety of banking-related businesses, including the ownership and operation of a savings association, or any entity engaged in consumer finance, equipment leasing, and mortgage banking and brokerage services. The BHCA does not place territorial restrictions on the domestic activities of nonbank subsidiaries of bank holding companies.
Additionally, bank holding companies that meet certain eligibility requirements prescribed by the BHCA and elect to operate as financial holding companies may engage in, or own shares in companies engaged in, a wider range of nonbanking activities, including securities and insurance underwriting and sales, merchant banking and any other activity that the Federal Reserve, in consultation with the Secretary of the Treasury, determines by regulation or order is financial in nature or incidental to any such financial activity, or that the Federal Reserve determines by order to be complementary to any such financial activity, as long as the activity does not pose a substantial risk to the safety or soundness of FDIC-insured institutions or the financial system generally. First Busey Corporation has elected to operate as a financial holding company. In order to maintain its status as a financial holding company, First Busey and Busey Bank must be well-capitalized, well-managed, and Busey Bank must have a least a satisfactory CRA rating. If the Federal Reserve determines that a financial holding company is not well-capitalized or well-managed, the Federal Reserve will provide a period of time in which to re-achieve compliance with those requirements, but during the period of noncompliance the Federal Reserve may place any limitations on the financial holding company that it deems appropriate. Furthermore, if the Federal Reserve determines that a financial holding company’s subsidiary bank has not received a satisfactory CRA rating, that financial holding company will not be able to commence any new financial activities or acquire a company that engages in such activities.
Change in Control
Federal law also prohibits any person or company from acquiring “control” of an FDIC-insured depository institution or its holding company without prior notice to the appropriate federal banking agency. “Control” is conclusively presumed to exist upon the acquisition of 25% or more of the outstanding voting securities of a bank or bank holding company but may arise under certain circumstances between 10% and 24.99% ownership.

Capital Requirements
Bank holding companies are required to maintain capital in accordance with Federal Reserve capital adequacy requirements. For a discussion of capital requirements, see “Item 1. Business—Supervision, Regulation and Other Factors—The Role of Capital” above.
Dividend Payments
First Busey Corporation's ability to pay dividends to its stockholders may be affected by both general corporate law considerations and the policies and capital requirements of the Federal Reserve applicable to bank holding companies. As a Nevada corporation, First Busey Corporation is subject to the limitations of Nevada law, which allows First Busey Corporation to pay dividends unless, after such dividend, (1) First Busey Corporation would not be able to pay its debts as they become due in the usual course of business or (2) First Busey Corporation’s total assets would be less than the sum of its total liabilities plus any amount that would be needed, if First Busey Corporation were to be dissolved at the time of the dividend payment, to satisfy the preferential rights upon dissolution of stockholders whose rights are superior to the rights of the stockholders receiving the distribution.
As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company should eliminate, defer, or significantly reduce dividends to stockholders if: (1) the company’s net income available to stockholders for the past four quarters, net of dividends previously paid during that period, is not sufficient to fully fund the dividends; (2) the prospective rate of earnings retention is inconsistent with the company’s capital needs and overall current and prospective financial condition; or (3) the company will not meet, or is in danger of not meeting, its minimum regulatory capital adequacy ratios. The Federal Reserve also possesses enforcement powers over bank holding companies and their nonbank subsidiaries to prevent or remedy actions that represent unsafe or unsound practices or violations of applicable statutes and regulations. Among these powers is the ability to proscribe the payment of dividends by banks and bank holding companies. In addition, under the Basel III Rule, banking organizations that want to pay unrestricted dividends must maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer. See “Item 1. Business—Supervision, Regulation and Other Factors—The Role of Capital” above.
Incentive Compensation
There have been a number of developments in recent years focused on incentive compensation plans sponsored by bank holding companies and their subsidiary banks, reflecting recognition by federal banking agencies and U.S. Congress that flawed incentive compensation practices in the financial industry were one of many factors contributing to the global financial crisis. The result is interagency guidance on sound incentive compensation practices for banking organizations.
The interagency guidance recognized three core principles. Effective incentive plans should: (1) provide employees with incentives that appropriately balance risk and reward; (2) be compatible with effective controls and risk-management; and (3) be supported by strong corporate governance, including active and effective oversight by the organization’s board of directors. Much of the guidance is directed at large banking organizations and, because of the size and complexity of their operations, the regulators expect those organizations to maintain systematic and formalized policies, procedures, and systems for ensuring that the incentive compensation arrangements for all executive and non-executive employees covered by this guidance are identified and reviewed, and appropriately balance risks and rewards. Under the interagency guidance, smaller banking organizations, like Busey, that use incentive compensation arrangements are expected to implement less extensive, formalized, and detailed policies, procedures, and systems than those of larger banks.
First Busey Corporation (BUSE) | 2024 — 18

Table of Contents Contents of Item 1. Business
In May 2024, certain of the federal banking and other financial services agencies released a proposed rule regarding certain incentive-based compensation arrangements at certain financial institutions with at least $1 billion in assets, as required under Section 956 of the Dodd-Frank Act. This proposal was largely based on an earlier 2016 proposal. The Federal Reserve and the SEC, however, did not join this proposal, signaling potential interagency misalignment and raising doubts regarding the likelihood of the proposed rule being finalized in its current form. The FDIC has indicated that the agencies will continue to coordinate to reach consensus, but it is not yet clear whether this initiative will continue during the current president’s administration.
Monetary Policy
The monetary policy of the Federal Reserve has a significant effect on the operating results of bank holding companies and their subsidiaries. Among the tools available to the Federal Reserve to affect the money supply are open market transactions in U.S. government securities and changes in the discount rate on bank borrowings. These tools are used in varying combinations to influence overall growth and distribution of bank loans, investments, and deposits, and their use may affect interest rates charged on loans or paid on deposits, which may impact the business and operations of Busey and Busey Bank.
Federal Securities Regulation
First Busey Corporation’s common stock is registered with the SEC under the Securities Act and the Exchange Act. Consequently, First Busey Corporation is subject to the information, proxy solicitation, insider trading and other restrictions and requirements of the SEC under the Exchange Act.
Corporate Governance
The Dodd-Frank Act addressed many investor protection, corporate governance, and executive compensation matters that will affect most U.S. publicly traded companies. It increased stockholder influence over boards of directors by requiring companies to give stockholders a nonbinding vote on executive compensation and so-called “golden parachute” payments, and it authorized the SEC to promulgate rules that would allow stockholders to nominate and solicit voters for their own candidates using a company’s proxy materials. The Dodd-Frank Act also directed the Federal Reserve, together with the other federal banking and financial services agencies, to promulgate rules prohibiting excessive compensation paid to executives of bank holding companies, regardless of whether such companies are publicly traded. As discussed in the “Incentive Compensation” section above, the federal banking and financial services agencies have proposed rules regarding incentive-based compensation arrangements for certain financial institutions, but no rule has been adopted at this time.
Supervision and Regulation of Busey Bank
General
Busey Bank is an Illinois-chartered bank. Its deposit accounts are insured by the FDIC’s Deposit Insurance Fund to the maximum extent provided under federal law and FDIC regulations, currently $250,000 per insured depositor category. As an Illinois-chartered FDIC-insured bank, Busey Bank is subject to the examination, supervision, reporting, and enforcement requirements of the DFPR, the chartering authority for Illinois banks. In October 2024, Busey Bank became a member of the Federal Reserve System, and as a result, Busey Bank became subject to the examination, reporting, regulatory, and enforcement requirements of the Federal Reserve. In addition, the FDIC, as administrator of its Deposit Insurance Fund, has regulatory authority over Busey Bank.
First Busey Corporation (BUSE) | 2024 — 19

Table of Contents Contents of Item 1. Business
Deposit Insurance
As an FDIC-insured institution, Busey Bank is required to pay deposit insurance premium assessments to the FDIC. The FDIC has adopted a risk-based assessment system whereby FDIC-insured institutions pay insurance premiums at rates based on their risk classification. For institutions like Busey Bank that are not considered large and highly complex banking organizations, the risk classification is based on examination ratings and financial ratios. A bank’s assessment is then calculated by multiplying its assessment rate by its assessment base (average consolidated total assets minus its average tangible equity). The total base assessment rates, effective as of January 1, 2023, currently range from 2.5 bps to 32 bps on an annualized basis. However, the maximum rate is 18 bps for FDIC-insured institutions in the top two categories of examination composite ratings.
At least semi-annually, the FDIC updates its loss and income projections for its Deposit Insurance Fund and, if needed, increases or decreases the assessment rates, following a notice and comment period on proposed rule making. For this purpose, the reserve ratio is the Deposit Insurance Fund balance divided by estimated insured deposits. In response to the global financial crisis, the Dodd-Frank Act increased the minimum reserve ratio from 1.15% to 1.35% of the estimated amount of total insured deposits. In its October 2024 semiannual update, the FDIC stated that the reserve ratio likely will reach the statutory minimum by the September 30, 2028, deadline, and no adjustments to the base assessment rates is currently projected.
In addition, because the total cost of the failures of Silicon Valley Bank and Signature Bank was approximately $24.1 billion, the FDIC adopted a special assessment for banking organizations with assets of $5 billion or more, at an annual rate of 13.4 bps beginning with the first quarterly assessment period of 2024 and an invoice payment date of June 28, 2024. The FDIC will continue to collect special assessments for an anticipated total of eight quarterly assessment periods. The base for the special assessment is equal to an insured depository institution’s estimated uninsured deposits for the December 31, 2022, reporting period, adjusted to exclude the first $5 billion in estimated uninsured deposits. Busey Bank, as part of a banking organization with assets of $5 billion or more, was technically subject to the FDIC special assessment; however, Busey Bank did not have to pay this assessment due to uninsured deposits being below the $5 billion exclusion threshold.
Supervisory Assessments
All Illinois-chartered banks are required to pay supervisory assessments to the DFPR to fund the operations of that agency. The amount of the assessment is calculated on the basis of each bank’s total assets. During the year ended December 31, 2024, Busey Bank paid supervisory assessments to the DFPR totaling approximately $0.8 million.
Capital Requirements
Banks are generally required to maintain capital levels in excess of other businesses. For a discussion of capital requirements, see “Item 1. Business—Supervision, Regulation and Other Factors—The Role of Capital” above.
Liquidity Requirements
Liquidity is a measure of the ability and ease with which bank assets may be converted to meet financial obligations to pay deposits or other funding sources. Banks are required to implement liquidity risk management frameworks that ensure they maintain sufficient liquidity, including a cushion of unencumbered, high quality, liquid assets to withstand a range of stress events. The level and speed of deposit outflows contributing to the failures of Silicon Valley Bank, Signature Bank, and First Republic Bank in the first half of 2023 was unprecedented and contributed to acute liquidity and funding strain on the financial industry. These events have further underscored the importance of liquidity risk management and contingency funding planning by insured depository institutions like Busey Bank, as highlighted in a 2023 addendum to interagency guidance on funding and liquidity risk management.
First Busey Corporation (BUSE) | 2024 — 20

Table of Contents Contents of Item 1. Business
Primary roles of liquidity risk management are to: (1) prospectively assess the need for funds to meet obligations; and (2) ensure the availability of cash or collateral to fulfill those needs at the appropriate time by coordinating the various sources of funds available to the institution under normal and stressed conditions. Basel III includes a liquidity framework that requires the largest insured institutions to measure their liquidity against specific liquidity tests. One test, referred to as the liquidity coverage ratio, is designed to ensure that the banking entity has an adequate stock of unencumbered high-quality liquid assets that can be converted easily and immediately in private markets into cash to meet liquidity needs for a 30-calendar day liquidity stress scenario. The other test, known as the net stable funding ratio, is designed to promote more medium- and long-term funding of the assets and activities of FDIC-insured institutions over a one-year horizon. These tests provide an incentive for banks and holding companies to increase their holdings in Treasury securities and other sovereign debt as a component of assets, increase the use of long-term debt as a funding source and rely on stable funding like core deposits (in lieu of brokered deposits).
Although these tests do not apply to Busey Bank, management continues to review its liquidity risk management framework in light of regulatory and industry developments. For instance, in July 2024, the FDIC released a request for information on deposits, soliciting information on whether, and to what extent, certain types of deposits may behave differently from each other (particularly during periods of economic or financial stress). At the present time, it is unclear how the FDIC may use the information that it gathered pursuant to this request, if at all. However, the possibility remains that the information obtained through this request, or through other requests by the FDIC or other banking agencies, may be used to make regulatory changes that could have a future impact on liquidity monitoring and risk management requirements applicable to Busey Bank.
Dividend Payments
The primary source of funds for First Busey Corporation is dividends from Busey Bank. Under Illinois banking law, Illinois-chartered banks generally may pay dividends only out of undivided profits. The DFPR may restrict the declaration or payment of a dividend by an Illinois-chartered bank. The Federal Reserve Act also imposes limitations on the amount of dividends paid by state member banks, such as Busey Bank. Without Federal Reserve approval, a state member bank may not pay dividends in any calendar year that, in the aggregate, exceed that bank’s calendar year-to-date net income plus the bank’s retained income for the two preceding calendar years.
The payment of dividends by any FDIC-insured institution is affected by the requirement to maintain adequate capital pursuant to applicable capital adequacy guidelines and regulations, and an FDIC-insured institution generally is prohibited from paying any dividends if, following payment thereof, the institution would be undercapitalized. Notwithstanding the availability of funds for dividends, the Federal Reserve, the FDIC, and the DFPR may prohibit the payment of dividends by Busey Bank if any of these banking agencies determines that such payment would constitute an unsafe or unsound practice. In addition, under the Basel III Rule, FDIC-insured institutions that want to pay unrestricted dividends must maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer.
State Bank Investments, Activities, and Acquisitions
Busey Bank is permitted to make investments and engage in activities directly or through subsidiaries as authorized by Illinois law. However, under federal law and FDIC regulations, FDIC-insured state banks are prohibited, subject to certain exceptions, from making or retaining equity investments of a type, or in an amount, that are not permissible for a national bank. Federal law and FDIC regulations also prohibit FDIC-insured state banks and their subsidiaries, subject to certain exceptions, from engaging as principal in any activity that is not permitted for a national bank unless the bank meets, and continues to meet, its minimum regulatory capital requirements, and the FDIC determines that the activity would not pose a significant risk to the Deposit Insurance Fund. These restrictions have not had, and are not currently expected to have, a material impact on the operations of Busey Bank.

Table of Contents Contents of Item 1. Business
Busey Bank may be required to seek approval from their applicable state regulator and the Federal Reserve (or in some cases, the FDIC) before engaging in certain acquisitions or mergers under applicable state and federal law. In 2024, each of the OCC and the FDIC separately released updated policy statements—and in the case of the OCC, a final rule—regarding how each banking agency reviews applications submitted pursuant to the Bank Merger Act based on statutory factors. The acting chairperson of the FDIC has indicated that the FDIC may seek to reverse the FDIC’s 2024 policy statement. Although the Federal Reserve, Busey Bank’s primary federal regulator, did not release any updated policy statement or rules regarding its review process under the Bank Merger Act in recent years, management of Busey Bank and Busey has considered the impact that the OCC’s and FDIC’s rules and guidance may have on the review of any relevant transactions that Busey Bank undertakes.
Insider Transactions
Busey Bank is subject to certain restrictions imposed by federal law on “covered transactions” between Busey Bank and its “affiliates.” First Busey Corporation is an affiliate of Busey Bank for purposes of these restrictions, and covered transactions subject to the restrictions include extensions of credit to First Busey Corporation, investments in the stock or other securities of First Busey Corporation, and the acceptance of the stock or other securities of First Busey Corporation as collateral for loans made by Busey Bank. The Dodd-Frank Act enhanced the requirements for certain transactions with affiliates, including an expansion of the definition of “covered transactions” and an increase in the amount of time for which collateral requirements regarding covered transactions must be maintained.
Certain limitations and reporting requirements are also placed on extensions of credit by Busey Bank to its directors and officers, to directors and officers of First Busey Corporation and its subsidiaries, to principal stockholders of First Busey Corporation, and to “related interests” of such directors, officers, and principal stockholders. In addition, federal law and regulations may affect the terms upon which any person who is a director or officer of First Busey Corporation or Busey Bank, or a principal stockholder of First Busey Corporation, may obtain credit from banks with which Busey Bank maintains a correspondent relationship.
Safety and Soundness Standards/Risk Management
Federal banking agencies have adopted operational and managerial standards to promote the safety and soundness of FDIC-insured institutions. The standards apply to internal controls, information systems, internal audit systems, loan documentation, credit underwriting, interest rate exposure, asset growth, compensation, fees and benefits, asset quality, and earnings.
In general, the safety and soundness standards prescribe the goals to be achieved in each area, and each institution is responsible for establishing its own procedures to achieve those goals. Although regulatory standards do not have the force of law, if an institution operates in an unsafe and unsound manner, the FDIC-insured institution’s primary federal regulator may require the institution to submit a plan for achieving and maintaining compliance. If an FDIC-insured institution fails to submit an acceptable compliance plan, or fails in any material respect to implement a compliance plan that has been accepted by its primary federal regulator, the banking agency is required to issue an order directing the institution to cure the deficiency. Until the deficiency cited in the agency’s order is cured, the agency may restrict the FDIC-insured institution’s rate of growth, require the FDIC-insured institution to increase its capital, restrict the rates the institution pays on deposits, or require the institution to take any action that the agency deems appropriate under the circumstances. Noncompliance with safety and soundness may also constitute grounds for other enforcement action by the federal banking agencies, including cease and desist orders and civil money penalty assessments.

Table of Contents Contents of Item 1. Business
During the past decade, banking agencies have increasingly emphasized the importance of sound risk management processes and strong internal controls when evaluating the activities of the FDIC-insured institutions they supervise. Properly managing risk has been identified as critical to the conduct of safe and sound banking activities, and has become even more important as new technologies, product innovation, and the size and speed of financial transactions have changed the nature of banking markets. The banking agencies have identified a spectrum of risks facing a banking organization including, but not limited to, credit, market, liquidity, operational, legal, and reputational risk. The key risk themes identified by Busey for 2024 are discussed under “Item 1A. Risk Factors” below. Busey Bank is expected to have active board and senior management oversight; adequate policies, procedures, and limits; adequate risk measurement, monitoring, and management information systems; and comprehensive internal controls. The federal banking agencies also have released specific risk management guidance on certain topics, including third-party relationships, in response to the proliferation of relationships between banking organizations and financial technology companies (although the guidance applies more broadly).
Privacy and Cybersecurity
Busey Bank is subject to many U.S. federal and state laws and regulations governing requirements for maintaining policies and procedures to protect non-public personal and other confidential information of its customers. These laws require Busey Bank to periodically disclose its privacy policies and practices relating to sharing such information and permit consumers to opt out of their ability to share information with unaffiliated third parties under certain circumstances. They also impact Busey Bank’s ability to share certain information with affiliates and non-affiliates for marketing and/or non-marketing purposes, or to contact customers with marketing offers. In addition, Busey Bank is required to implement a comprehensive information security program that includes administrative, technical, and physical safeguards to ensure the security and confidentiality of customer records and information. These security and privacy policies and procedures, for the protection of personal and confidential information, are in effect across all businesses and geographic locations. Busey Bank and Busey also are subject to a number of federal and state laws and regulations requiring notifications and disclosures regarding certain cybersecurity incidents. Busey Bank must also consider and address cybersecurity considerations as part of its risk management processes.
Branching Authority
Illinois banks, such as Busey Bank, have the authority under Illinois law to establish branches anywhere in the State of Illinois, subject to receipt of all required regulatory approvals. The Dodd-Frank Act permits well-capitalized and well-managed banks to establish new interstate branches or acquire individual branches of a bank in another state (rather than the acquisition of an out-of-state bank in its entirety) without impediments. Federal law permits state and national banks to merge with banks in other states subject to: (1) regulatory approval; (2) federal and state deposit concentration limits; and (3) state law limitations requiring the merging bank to have been in existence for a minimum period of time (not to exceed five years) prior to the merger.
Federal Home Loan Bank System
Busey Bank is a member of a FHLB, which serves as a central credit facility for its members. The FHLB is funded primarily from proceeds from the sale of obligations of the FHLB system. It makes loans to member banks in the form of FHLB advances. All advances from the FHLB are required to be fully collateralized as determined by the FHLB.

Community Reinvestment Act Requirements
The CRA requires Busey Bank to have a continuing and affirmative obligation in a safe and sound manner to help meet the credit needs of the entire community, including low- and moderate-income neighborhoods. Federal banking agencies regularly assess Busey Bank’s record of meeting the credit needs of its communities in dedicated examinations. Busey Bank’s CRA ratings derived from these examinations can have significant impacts on the activities in which Busey Bank and Busey may engage. For example, a low CRA rating may impact the review of applications for acquisitions by Busey Bank, or Busey’s financial holding company status.
On October 24, 2023, the banking agencies issued a final rule to strengthen and modernize the CRA regulations (the "CRA Rule"). Management of Busey Bank has effectively assessed the impact of the CRA Rule on its CRA lending and investment activities in its respective markets and continues to align its program with current and future expectations.
The CRA Rule is designed to update how CRA activities qualify for consideration, where CRA activities are considered, and how CRA activities are evaluated. More specifically, the banking agencies described the goals of the CRA Rule as follows: (1) to expand access to credit, investment, and basic banking services in low and moderate-income communities; (2) to adapt to changes in the banking industry, including mobile and internet banking by modernizing assessment areas while maintaining a focus on branch-based areas; (3) to provide greater clarity, consistency, and transparency in the application of the regulations through the use of standardized metrics as part of CRA evaluations and clarifying eligible CRA activities focused on low- and moderate-income communities and under-served rural communities; (4) to tailor CRA rules and data collection to bank size and business model; and (5) to maintain a unified approach among the regulators.
In 2022, Busey Bank, like all Illinois chartered banks, became subject to state-level CRA standards, following passage of the Illinois CRA. This means that, in addition to the federal CRA review, Busey Bank will be reviewed by the DFPR to assess Busey Bank’s record of meeting the credit needs of its communities. Like the potential impact under the federal CRA, applications for additional acquisitions or activities would be affected by the evaluation of Busey Bank’s effectiveness in meeting its Illinois CRA requirements.
Anti-Money Laundering/Countering the Financing of Terrorism/Sanctions
The Bank Secrecy Act is the common name for a series of laws and regulations enacted in the United States to combat money laundering and the financing of terrorism. These laws and regulations are designed to deny terrorists and criminals the ability to obtain access to the U.S. financial system and have significant implications for FDIC-insured institutions and other businesses involved in the transfer of money. The so-called Anti-Money Laundering/Countering the Financing of Terrorism regime under the Bank Secrecy Act provides a foundation to promote financial transparency and deter and detect those who seek to misuse the U.S. financial system to launder criminal proceeds, finance terrorist acts, or move funds for other illicit purposes. The laws mandate financial services companies to have policies and procedures with respect to measures designed to address the following matters: (1) customer identification programs; (2) money laundering; (3) terrorist financing; (4) identifying and reporting suspicious activities and currency transactions; (5) currency crimes; and (6) cooperation between FDIC-insured institutions and law enforcement authorities. Busey Bank must also comply with stringent economic and trade sanctions regimes administered and enforced by the Office of Foreign Assets Control.

Concentrations in Commercial Real Estate
Concentration risk exists when FDIC-insured institutions deploy too many assets to any one industry or segment. A concentration in CRE is one example of regulatory concern that has, in recent years, been subject to additional scrutiny by federal banking agencies as well as the SEC for publicly-traded banking organizations. The interagency CRE Guidance provides supervisory criteria, including the following numerical indicators, to assist bank examiners in identifying banks with potentially significant CRE loan concentrations that may warrant greater supervisory scrutiny: (1) CRE loans exceeding 300% of capital and increasing 50% or more in the preceding three years; or (2) construction and land development loans exceeding 100% of capital. The CRE Guidance does not limit banks’ levels of CRE lending activities, but rather guides institutions in developing risk management practices and levels of capital that are commensurate with the level and nature of their CRE concentrations. On December 18, 2015, and again in more recent years, the federal banking agencies have issued statements to reinforce prudent risk-management practices related to CRE lending, having observed substantial growth in many CRE asset and lending markets, increased competitive pressures, rising CRE concentrations in banks, and an easing of CRE underwriting standards. The federal banking agencies have reminded FDIC-insured institutions to maintain underwriting discipline and exercise prudent risk-management practices to identify, measure, monitor, and manage the risks arising from CRE lending. In addition, FDIC-insured institutions must maintain capital commensurate with the level and nature of their CRE concentration risk. As of December 31, 2024, Busey Bank did not exceed these guidelines.
Consumer Financial Services
The historical structure of federal consumer protection regulation applicable to all providers of consumer financial products and services changed significantly on July 21, 2011, when the CFPB commenced operations to supervise and enforce consumer protection laws. The CFPB has broad rulemaking authority for a wide range of consumer protection laws that apply to all providers of consumer products and services, including Busey Bank, as well as the authority to prohibit “unfair, deceptive or abusive” acts and practices. The CFPB has examination and enforcement authority over providers with more than $10 billion in assets. Busey Bank is under CFPB oversight for consumer banking transactions.
Because abuses in connection with residential mortgages were a significant factor contributing to the global financial crisis, many initial rules issued by the CFPB and required by the Dodd-Frank Act addressed mortgage and mortgage-related products, their underwriting, origination, servicing, and sales. The Dodd-Frank Act significantly expanded underwriting requirements applicable to loans secured by 1-4 family residential real property and augmented federal law combating predatory lending practices. In addition to numerous disclosure requirements, the Dodd-Frank Act and the CFPB’s enabling regulations imposed new standards for mortgage loan originations on all lenders, including banks and savings associations, in an effort to strongly encourage lenders to verify a borrower’s ability to repay, while also establishing a presumption of compliance for certain “qualified mortgages.” The CFPB has from time to time released additional rules as to qualified mortgages and the borrower’s ability to repay.
First Busey Corporation (BUSE) | 2024 — 25

Table of Contents Contents of Item 1. Business
Over the last several years, the CFPB has taken an aggressive approach to the regulation and supervision, where applicable, of providers of consumer financial products and services. In particular, the CFPB has taken, or attempted to take, a proactive, multi-front approach to protect consumers from excessive overdraft and non-sufficient funds fees. This includes proposed and final rules, interpretive opinions, and enforcement actions. In 2024, the CFPB finalized a rule that eliminated an exemption for overdraft fees from lending laws (the “Overdraft Rule”). The Overdraft Rule, which has an effective date of October 1, 2025, applies to financial institutions, such as FDIC-insured institutions, with over $10 billion in assets , like Busey Bank, and provides several different options on how to approach charging overdraft fees. Busey expects that the implementation of this rule may result in a decrease in fee income. Several banks and trade associations have sued the CFPB regarding the Overdraft Rule, claiming that the CFPB has exceeded its regulatory authority. The CFPB is now under new acting leadership and has paused much of its existing work. It remains unclear what this will mean for the agency and its oversight of consumer protection laws and regulations. Though some of the CFPB’s rulemakings are under review, the laws, rules, and regulations that the agency has enforced since its inception currently remain intact and could be enforced by other banking agencies.
Consumer protection rules have an impact on Busey Bank’s operations, including by increasing compliance costs and potentially negatively affecting earnings. Busey Bank must also comply with certain state consumer protection laws and requirements in the states in which it operates.
SECURITIES AND EXCHANGE COMMISSION REPORTING AND OTHER INFORMATION
Busey makes its Annual Reports, Quarterly Reports, Current Reports, and any amendments thereto available, free of charge, on its website at busey.com as soon as reasonably practicable after such reports are electronically filed with or furnished to the SEC. Reference to Busey’s website does not constitute incorporation by reference of the information contained on the website and it should not be considered part of this document.
The SEC maintains an internet site at sec.gov, which contains reports, proxy and information statements, and other information regarding issuers that file electronically with the SEC, and from which Busey’s SEC filings may be accessed.
NON-GAAP FINANCIAL INFORMATION
This Annual 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 statutory rates, 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.

ITEM 1A. RISK FACTORS
This section highlights the risks management believes could adversely affect Busey’s financial performance. Additional risks that could affect Busey adversely and cannot be predicted may arise at any time. Further, risks that are immaterial at this time may have an adverse impact on Busey’s future financial condition.

ECONOMIC AND MARKET RISKS
Conditions in the financial market and economic conditions, including conditions in the states in which it operates, generally may adversely affect Busey’s business.
Busey’s general financial performance is highly dependent upon the business environment in the markets where it operates and, in particular, the ability of borrowers to pay interest on, and repay principal of, outstanding loans, and the value of collateral securing those loans, as well as demand for loans and other products and services it offers. A favorable business environment is generally characterized by, among other factors, economic growth, efficient capital markets, low inflation, low unemployment, high business and investor confidence, and strong business earnings. Unfavorable or uncertain economic and market conditions can be caused by declines in economic growth, business activity, or investor or business confidence; limitations on the availability, or increases in the cost, of credit and capital; increases in inflation or interest rates; high unemployment; natural disasters; or a combination of these or other factors.
Given the complex factors affecting the strength of the U.S. economy, including uncertainties regarding the persistence of inflation; geopolitical developments, such as ongoing conflicts in the Middle East and the Russian invasion of Ukraine, and resulting disruptions in the global energy market; tight labor market conditions domestically; supply chain issues both domestically and internationally; and the potential effects of the new presidential administration, including its response to the foregoing, potential imposition of new tariffs, mass deportations and changes to tax or other financial regulations, uncertainty surrounding future changes may adversely affect Busey’s operating environment and therefore its business, financial condition, results of operations, and growth prospects.
Shifts in consumer and business behavior during economic uncertainty may impact Busey’s business.
Uncertainty regarding economic conditions may result in changes in consumer and business spending, borrowing, and savings habits. Downturns in the markets where Busey’s banking operations occur could result in a decrease in demand for Busey’s products and services, an increase in loan delinquencies and defaults, high or increased levels of problem assets and foreclosures, and reduced wealth management fees resulting from lower asset values. Such conditions could adversely affect the credit quality of Busey’s loans, financial condition, and results of operations.
First Busey Corporation (BUSE) | 2024 — 35

Table of Contents Contents of Item 1A. Risk Factors
Regional economic vulnerabilities and reliance on key industries may heighten risks.
Busey currently conducts its banking operations in central and suburban Chicago, Illinois; the St. Louis, Missouri metropolitan area; central Indiana; and southwest Florida. Busey operates in markets with a significant university and healthcare presence. These industries rely heavily on state and federal funding and contracts. Timely payments by the State of Illinois to its vendors and government-sponsored entities, as well as potential federal changes to healthcare laws, could affect Busey’s primary market areas, which could in turn affect its financial condition and results of operations. A small part of Busey’s business resides in Florida, which can be affected by inclement weather.
Prolonged elevated interest rates followed by easing cycles create financial volatility.
Prolonged periods of elevated interest rates followed by an easing cycle pose significant challenges and opportunities for Busey. While an easing cycle, which is characterized by the FOMC taking action to reduce interest rates, can alleviate some funding pressures and encourage borrowing, it also introduces risks to the banking sector. A rapid shift in rates can compress net interest margins, disrupt asset-liability management, and affect the valuation of financial instruments.
After a series of rate hikes starting in March 2022, the FOMC began an easing cycle in September 2024, responding to slowing inflation and economic growth. As of December 2024, the federal funds target range was reduced to 4.25%–4.5%, marking a gradual reversal from the peak of 5.25%–5.5% in 2023. This shift reflects a softening economic environment, with the FOMC aiming to balance inflation reduction while avoiding a sharp contraction in economic activity.
Declining interest rates result in reduced income from lending and investment activities, and may drive consumers to seek higher-yielding alternatives outside of traditional banking, both of which could negatively impact Busey’s liquidity and results of operations.
While rate cuts can stimulate loan demand, they also create potential threats to the banking sector. Falling interest rates may reduce yields on loans and securities more quickly than the cost of deposits declines, narrowing margins. Deposit outflows could accelerate if customers seek higher-yielding alternatives outside traditional banking, further challenging liquidity. Lower rates can lead to prepayments on fixed-rate loans, impacting the value of interest-earning assets and requiring adjustments to portfolios.
Despite these risks, the easing cycle may present opportunities for growth. Lower rates can revitalize loan demand, particularly in key areas such as mortgages, auto loans, and small business lending, while providing some relief to borrowers under stress. However, the broader economic environment, including rising consumer debt levels, increasing delinquencies, and persistent inflation risks could still impact Busey’s financial condition, liquidity, and overall performance.
REGULATORY AND LEGAL RISKS
Changes in government policies and regulatory frameworks could adversely affect operations and profitability.
Changes in policy and at banking agencies, including changes in interpretation and prioritization, occur over time through policy and personnel changes following federal- and state-level elections, which lead to changes involving the level of oversight and focus on the financial services industry. The nature, timing, and economic and political effects of potential changes to the current legal and regulatory framework affecting financial institutions remain highly uncertain in connection with a change in presidential administration.
First Busey Corporation (BUSE) | 2024 — 36

Table of Contents Contents of Item 1A. Risk Factors
Economic conditions, including interest rates, inflation, and consumer spending, may be influenced by shifts in government leadership and policies, affecting Busey’s operations. Additionally, heightened regulatory scrutiny, particularly in consumer compliance, anti-money laundering, and cybersecurity increases operational and compliance burdens for Busey.
As Busey continues to grow in asset size and complexity, regulatory expectations and scrutiny will increase and could have a potential impact on Busey’s operations and business.
As Busey’s assets grow, so do regulatory expectations. The planned acquisition of CrossFirst amplifies the complexity of compliance. Certain regulations and laws have embedded asset thresholds that increase scrutiny, reporting requirements, and operational demands. For example, the Dodd-Frank Act includes thresholds for asset size that trigger enhanced oversight. Busey’s continued expansion necessitates adapting its compliance frameworks to meet these increasing demands. Failure to manage compliance risks effectively could result in regulatory violations, leading to significant fines, penalties, and legal costs. Additionally, non-compliance could damage Busey's reputation, erode customer trust, and undermine investor confidence, resulting in a negative impact to Busey’s market valuation. It could also lead to further scrutiny from regulators, potentially hindering future growth opportunities.
Evolving privacy, data protection, and information security laws and regulations present operational and legal challenges.
In the normal course of business, Busey collects, processes, and retains sensitive and confidential information regarding its customers, and Busey’s collection and handling of such information is subject to regulatory scrutiny. There has been a heightened legislative and regulatory focus on privacy, data protection, and information security. New or revised laws and regulations, including with the respect to the use of artificial intelligence by financial institutions and service providers, may significantly impact Busey’s current and planned privacy, data protection, and information security-related practices; the collection, use, retention, and safeguarding of customer and employee information; and current or planned business activities. Compliance with current or future privacy, data protection, and information security laws could result in higher compliance and technology costs and could restrict Busey’s ability to provide certain products and services, which could adversely affect Busey’s business.
Laws impacting cannabis-related businesses may have an impact on Busey’s operations and risk profile.
The Controlled Substances Act makes it illegal under federal law to manufacture, distribute, or dispense marijuana. Starting January 1, 2020, however, the Illinois Cannabis Regulation and Tax Act began permitting adults 21 years or older to legally purchase marijuana for recreational use from licensed dispensaries. Further, voters in Missouri approved an amendment to the state constitution that began permitting adults 21 years and older to legally purchase marijuana for recreational use from licensed dispensaries starting February 3, 2023. It is Busey Bank’s current practice to avoid knowingly providing banking products or services to entities or individuals that: (1) directly or indirectly manufacture, distribute, or dispense marijuana or hemp products, or those with a significant financial interest in such entities; or (2) derive a material amount of revenue from providing products or services to, or other involvement with, such entities. Busey Bank uses reasonable measures, including appropriate new account screening and customer due diligence measures, to ensure that existing and potential customers that operate in the states in which the Bank operates do not engage in any such activities. Nonetheless, shifts in Illinois and Missouri law legalizing cannabis use, along with shifts in Florida law allowing medicinal use and decriminalizing possession, have increased the number of direct and indirect cannabis-related businesses in some of the states in which Busey operates, and therefore increases the likelihood that Busey Bank could interact with such businesses, as well as their owners and employees. Such interactions could create additional legal, regulatory, strategic, and reputational risk to Busey Bank and First Busey Corporation.
First Busey Corporation (BUSE) | 2024 — 37

Table of Contents Contents of Item 1A. Risk Factors
Busey is or may become involved from time to time in suits, legal proceedings, information-gathering requests, investigations, and proceedings by governmental and self-regulatory agencies that may lead to adverse consequences.
Busey may be subject to lawsuits, governmental inquiries, or self-regulatory reviews. These proceedings could result in penalties, adverse judgments, or operational restrictions. While accruals are established for legal contingencies when losses are probable and estimable, outcomes may exceed these amounts, and accordingly, Busey’s ultimate losses may be higher, possibly significantly so, than the amounts accrued for legal loss contingencies, which could adversely affect Busey’s financial condition and results of operations.
See “Note 18. Outstanding Commitments and Contingent Liabilities” in the Notes to the Consolidated Financial Statements for information regarding 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.
CREDIT AND LENDING RISKS
Heightened credit risk associated with lending activities may result in insufficient credit loss provisions, which could have material adverse effects on Busey’s results of operations and financial condition.
Busey’s lending activities involve inherent risks, including borrower nonpayment, fluctuations in collateral value, and the effects of economic and market conditions. These risks have been amplified by recent economic factors, such as elevated interest rates, inflationary pressures, and a more cautious economic outlook. Busey employs rigorous underwriting standards, monitors industry and geographic loan concentrations, and conducts both internal and external independent loan reviews to mitigate these risks. Despite these efforts, credit risks cannot be entirely eliminated, and borrower defaults could lead to increased non-performing loans, charge-offs, delinquencies, and higher ACL provisions.
Busey’s commercial loan portfolio reflects a strategic focus on maintaining robust credit quality. However, there are inherent risks in any lending activity, including uncertainties in collateral values, borrower cash flows, and broader economic conditions. To mitigate credit risk, Busey employs rigorous loan approval procedures, monitors concentrations within industries and geographic locations, and conducts independent reviews through internal and external assessments. Stress testing at both the borrower and portfolio levels helps identify vulnerabilities, but such measures cannot fully eliminate credit risks. Borrowers across various industries may face challenges due to sector-specific pressures or macroeconomic factors, which could lead to elevated non-performing loans, charge-offs, or provisioning needs.
Busey establishes the ACL based on detailed analyses of the loan portfolio and broader market conditions, incorporating management judgments and forward-looking forecasts. While management considers the ACL adequate to absorb probable losses, unforeseen economic disruptions or borrower-specific events could necessitate additional provisions, adversely affecting financial performance.
High levels of non-performing assets could reduce Busey’s profitability and strain operational resources.
Non-performing assets negatively impact Busey’s financial condition through lost interest income, increased loan administration costs, and adverse effects on efficiency ratios. The resolution of these assets demands significant management attention and regulatory compliance, which can divert resources from other priorities. Non-performing loans and OREO properties elevate Busey’s risk profile and require ongoing vigilance to minimize financial and operational disruptions.
First Busey Corporation (BUSE) | 2024 — 38

Table of Contents Contents of Item 1A. Risk Factors
Loan concentrations in volatile markets could increase Busey’s exposure to economic downturns, adversely impacting financial stability.
Busey may have higher credit risk, or experience higher credit losses, to the extent its loans are concentrated by loan type, industry segment, borrower type, or geographic location of the borrower or collateral. CRE represents an important component of Busey’s loan portfolio and is inherently sensitive to economic fluctuations. Busey’s two primary categories of CRE are (1) CRE that is occupied by the property owner, and (2) CRE that is held as investment property. The risks associated with these categories differ, as provided below:
•Occupant owned CRE: The repayment of occupant owned CRE loans is largely dependent on the performance of the underlying business occupying the property. If the borrower’s business experiences financial challenges or operational disruptions, it may impact their ability to service the loan. However, occupant owned CRE loans generally benefit from the borrower’s vested interest in maintaining the property for their own business operations, which may reduce the risk of customer default.
•Investor owned CRE: In contrast, investor owned CRE loans are primarily reliant on property cash flows generated by third-party tenants. These loans are particularly sensitive to factors such as reduced rental income, higher vacancy rates, and regulatory changes. Declines in market demand, economic downturns, or increased tenant defaults could significantly impact the borrower’s ability to repay these loans.
Declining borrower cash flows and fluctuating collateral values may lead to significant losses across Busey’s commercial loan portfolio.
Busey’s commercial loans are primarily underwritten based on the identified cash flow of the borrower, with collateral serving as secondary support. Credit enhancements often include pledged collateral and personal guarantees, which enhance the likelihood of repayment. However, the availability of funds for repayment—particularly for loans secured by accounts receivable—may depend significantly on the borrower’s ability to collect from their customers. In periods of economic recession, this capacity could decline, increasing repayment risks.
Collateral securing loans may depreciate over time, be difficult to appraise, or fluctuate in value based on the borrower’s business performance. With larger commercial loans and the less readily marketable nature of collateral, even a small number of loan loss incidents could materially impact Busey’s financial condition and operational results.
Real estate construction, land acquisition, and development loans are based upon estimates of costs and values associated with the complete project. These estimates may be inaccurate, and Busey may be exposed to significant losses on loans for these projects.
Construction, land acquisition, and development loans involve additional risks because funds are advanced upon the security of the project, which is of uncertain value prior to its completion, and costs may exceed realizable values in declining real estate markets. Because of the uncertainties inherent in estimating construction costs and the realizable market value of the completed project, and the effects of governmental regulation on real property, it is relatively difficult to evaluate accurately the total funds required to complete a project and to estimate the related loan-to-value ratio. As a result, construction loans often involve the disbursement of substantial funds with repayment dependent, in part, on the success of the ultimate project and the ability of the borrower to sell or lease the property, rather than the ability of the borrower or guarantor to repay principal and interest. If Busey’s appraisal of the value of the completed project proves to be overstated, or market values or rental rates decline, there may be inadequate security for the repayment of the loan upon completion of construction of the project. If Busey is forced to foreclose on a project prior to or at completion due to a default, there can be no assurance that it will be able to recover all of the unpaid balance of, and accrued interest on, the loan as well as related foreclosure and holding costs. In addition, Busey may be required to fund additional amounts to complete the project and may have to hold the property for an unspecified period of time while it attempts to dispose of it.
First Busey Corporation (BUSE) | 2024 — 39

Table of Contents Contents of Item 1A. Risk Factors
Credit quality deterioration in investment securities may result in significant realized losses, impacting Busey’s financial performance.
Busey’s investment portfolio includes securities issued by government-sponsored agencies and non-government entities. While these securities offer portfolio diversification, they are subject to risks such as credit downgrades, collateral underperformance, and issuer defaults. These factors could result in realized losses, negatively impacting Busey’s financial condition and results of operations.
CAPITAL AND LIQUIDITY RISKS
Failure to maintain sufficient capital to meet regulatory requirements could have material adverse effects on financial condition, liquidity, results of operations, and regulatory compliance.
Busey must meet regulatory capital requirements and maintain sufficient liquidity. Busey’s ability to raise additional capital as needed will depend on conditions in the capital markets, economic conditions, and a number of other factors, including investor perceptions regarding the banking industry, market conditions, and governmental activities, many of which are outside Busey’s control, as well as on its financial condition and performance. Accordingly, Busey cannot guarantee that it will be able to raise additional capital if needed or on terms acceptable to the Company. In particular, if Busey is required to raise additional capital in the current interest rate environment, Busey believes the pricing and other terms investors may require in such an offering may not be attractive to the Company.
Busey’s failure to continue to maintain capital ratios in excess of the amounts necessary to be considered “well-capitalized” for bank regulatory purposes could affect customer confidence, its ability to grow, its costs of funds, the cost of FDIC insurance, its ability to pay dividends to its stockholders on outstanding stock, its ability to make acquisitions, and its business, results of operations, and financial condition. Furthermore, under FDIC rules, if Busey ceases to meet the requirements to be considered a “well-capitalized” institution for bank regulatory purposes, the interest rates it pays on deposits and its ability to accept, renew, or rollover deposits, particularly brokered deposits, may be restricted.
Liquidity risks could affect operations and jeopardize Busey’s business, financial condition, and results of operations.
Liquidity is essential to Busey’s business. An inability to raise funds through deposits, borrowings, sales of securities, sales of loans, and other sources could have a substantial negative effect on liquidity. Busey’s primary sources of funds consist of deposits and funds from sales of investment securities, investment maturities and sales, and cash from operations. Additional liquidity is available through repurchase agreements, brokered deposits, and the ability to borrow from the Federal Reserve Bank and the FHLB. Access to funding sources in amounts adequate to finance or capitalize Busey’s activities or on terms that are acceptable to the Company could be impaired by factors that affect it directly or the financial services industry or economy in general, such as disruptions in the financial markets or negative views and expectations about the prospects for the financial services industry. In addition, increased competition with the largest banks and fintechs for retail deposits may impact Busey’s ability to raise funds through deposits and could have a negative effect on Busey’s liquidity. Any decline in available funding and/or capital could adversely impact Busey’s ability to originate loans, invest in securities, meet its expenses, pay dividends to its stockholders, or meet deposit withdrawal demands, any of which could have a material adverse impact on its liquidity, business, financial condition, and results of operations.

COMPETITIVE AND STRATEGIC RISKS
If securities or industry analysts do not publish or cease publishing research reports about Busey, if they adversely change their recommendations regarding Busey’s stock, or if Busey’s operating results do not meet their expectations, the price of Busey’s stock could decline.
The trading market for Busey’s common stock is significantly influenced by research and reports from industry analysts. Limited or negative analyst coverage could reduce the stock’s demand, market price, and trading volume. Downgrades, unfavorable comparisons with competitors, or operating results that fall short of analyst expectations may further negatively affect stock performance. The cessation of analyst coverage could exacerbate these challenges, diminishing interest in Busey’s stock.
Intense competition from traditional banks and fintech companies threatens market share.
Busey operates in highly competitive markets across Illinois, Missouri, Indiana, and Florida, with competitors ranging from national and regional banks to fintech companies offering digital-first solutions. The rise of financial technology has introduced new challengers, including non-banks and large technology corporations, that offer services traditionally provided by banks, such as credit issuance, payment processing, and deposit alternatives.
Technological innovations, such as digital wallets, peer-to-peer lending, and blockchain-based transactions attract consumer interest and present a risk of disintermediation, where banks are bypassed as intermediaries. To remain competitive, Busey must continuously invest in innovation and adapt to evolving customer preferences. Failure to do so could lead to reduced loans, deposits, commissions, and profitability, adversely impacting Busey’s financial performance.
Failure to adapt to rapid technological advancements could erode competitiveness.
Technological advancements are reshaping the financial services industry, requiring organizations to balance external competitiveness with internal technological efficiency. Meeting evolving customer expectations for convenience, security, and personalization requires significant investment in innovation and adaptation. Falling behind in the adoption of innovative technologies could result in difficulties attracting new customers, retaining existing ones, and maintaining competitiveness.
Emerging trends, such as generative artificial intelligence, have the potential to disrupt the industry. Although generative artificial intelligence offers opportunities to enhance operational efficiency, it also introduces risks, including fraud, security vulnerabilities, and compliance challenges. While incorporating new technologies into Busey’s business is important in maintaining competitiveness, implementation of such technologies must prioritize security and compliance, which may delay its adoption.
Busey’s strategy of pursuing acquisitions exposes Busey to financial, execution, and operational risks that could negatively affect Busey.
Acquisitions remain a cornerstone of Busey’s growth strategy, exemplified by the planned CrossFirst acquisition. While acquisitions provide opportunities for earnings enhancement and market expansion, they also involve significant risks:
•Integration Risks: Aligning systems, procedures, and personnel as well as harmonizing organizational cultures can be complex and disruptive, potentially negatively impacting customers. To realize anticipated benefits from a merger, Busey must successfully integrate an acquired company into its existing businesses, risk management framework, compliance systems, and corporate culture, in a manner that permits the anticipated benefits to be realized and that does not materially disrupt existing client relationships or result in decreased revenues due to the loss of clients.
First Busey Corporation (BUSE) | 2024 — 41

Table of Contents Contents of Item 1A. Risk Factors
•Credit Quality and Unknown Liabilities: Acquired assets may carry hidden risks that adversely affect financial performance. Insufficient or inadequate due diligence, beyond credit quality, could exacerbate these challenges.
•Market Conditions: The price of acquisitions fluctuates with market conditions. Busey has experienced times during which acquisitions could not be made in specific markets at prices that Busey’s management considered acceptable, and Busey expects that it will experience this condition in the future in one or more markets.
•Employee Attrition: The integration process can lead to employee turnover, particularly among key personnel. The success of a merger is dependent, in part, on Busey’s ability to retain the talents and dedication of key employees. During an acquisition, it is possible that key employees may decide not to remain with the acquired company while the merger is pending or with Busey after the merger. If Busey is unable to retain key employees, including management, who are critical to the successful integration and future operations of the combined company, Busey could face disruptions in its operations, loss of key information, expertise, or know-how, and unanticipated additional recruitment costs. In addition, following a merger, if key employees terminate their employment, Busey’s business activities may be adversely affected, and management’s attention may be diverted from successfully hiring suitable replacements, all of which may cause Busey’s business to suffer.
•Financing Challenges: Acquisitions often require incurring debt or issuing new shares, thereby increasing Busey’s leverage and diminishing its liquidity. Issuing capital stock to the sellers in an acquisition or to third-parties to raise capital could dilute the interests of Busey’s existing stockholders. Issuance of new shares of Busey common stock may result in fluctuations in the market price of Busey common stock, including a stock price decrease.
•Substantial acquisition costs: With any acquisition, Busey may incur a number of non-recurring costs associated with the merger and integration. These costs include legal, financial advisory, accounting, consulting and other advisory fees, severance/employee benefit-related costs, public company filing fees and other regulatory fees, printing costs, system conversion costs, added facilities costs, and other related costs. Further, Busey could incur due diligence expenses which may not result in an acquisition.
•Delayed or unrealized benefits: The time period in which anticipated benefits of a merger are fully realized may take longer than anticipated, or Busey may be unsuccessful in realizing the anticipated benefits from mergers and future acquisitions.
Introduction of new products and services carries financial and strategic risks.
Busey strives to serve customers with a competitive product set and relevant services. While introducing new lines of business or innovative products and services supports this goal, these efforts carry inherent risks. Competitive pressures, underdeveloped markets, or unforeseen challenges can lead to delayed timelines and missed profitability targets. Significant investments in technology and marketing may not yield the desired outcomes, potentially negatively affecting operating results.
Digital asset trends introduce regulatory, competitive and scalability challenges.
While Busey does not currently offer digital asset products, such as cryptocurrencies or stablecoins, the global adoption of digital assets presents competitive and regulatory challenges. The appeal of digital assets lies in their transaction speed, cross-border capabilities, and anonymity. However, these attributes also introduce risks, including fraud, volatility, and limited regulatory oversight.
First Busey Corporation (BUSE) | 2024 — 42

Table of Contents Contents of Item 1A. Risk Factors
As digital asset adoption grows, Busey must remain vigilant to market dynamics and regulatory developments. Additionally, the ability to effectively and efficiently scale operations to meet customer demand is critical. Failure to scale effectively could constrain Busey’s ability to invest in competitive products, hampering long-term growth and competitiveness.
Busey’s ability to navigate competitive pressures and strategic challenges depends on proactive investments in innovation, efficient integration of acquisitions, and the ability to anticipate and adapt to emerging trends.
ACCOUNTING AND TAX RISKS
Financial statements are created, in part, by estimates, assumptions, and methods used by management, which, if incorrect, could cause unexpected losses in the future.
Busey’s financial performance is impacted by accounting principles, policies, and guidelines. Some of these policies require the use of estimates and assumptions that may affect the value of assets or liabilities and financial results. Certain accounting policies are critical and require management to make subjective and complex judgments about matters that are inherently uncertain, and materially different amounts could be reported under different conditions or using different assumptions. If such estimates or assumptions underlying Busey’s Consolidated Financial Statements are incorrect, the Company may experience material losses.
One such assumption and estimate is the valuation analysis of Busey’s goodwill and other intangible assets. Although Busey’s analysis does not indicate impairments exist, the Company is required to perform additional impairment assessments on at least an annual basis, which could result in future impairment charges. Any future impairment of goodwill or other intangible assets, whether based on the current balances or future balances arising out of acquisitions, could have a material adverse effect on the results of operations by reducing net income or increasing net losses.
Changes in accounting principles or guidelines could adversely affect financial reporting.
Periodically, agencies such as the FASB or the SEC change the financial accounting and reporting standards or the interpretation of those standards that govern the preparation of Busey’s Financial Statements. These changes are beyond Busey’s control, can be difficult to predict, and could materially impact how Busey reports its financial condition and results of operations. In addition, trends in financial and business reporting, including environmental, social, and governance related disclosures, could require Busey to incur additional reporting expense. Changes in these standards are continuously occurring, and the implementation of such changes could have a material adverse effect on Busey’s financial condition and results of operations.
Busey is subject to changes in tax law and may not realize tax benefits which could adversely affect its results of operations.
Changes in tax laws at national or state levels could have an effect on Busey’s short-term and long-term earnings. Tax law changes are both difficult to predict and beyond Busey’s control. Changes in tax laws could affect Busey’s earnings, its customers’ financial positions, or both.
Deferred tax assets are designed to reduce subsequent period income tax expense. They arise, in part, as a result of net loss carry-overs, and other book accounting to tax accounting differences, for items such as expected credit losses, stock-based compensation, and deferred compensation. Deferred tax assets are recorded for such items when it is anticipated that the tax consequences will be recognized in earnings in future periods. A valuation allowance is established against a deferred tax asset when it is unlikely the future tax effects will be realized. Significant judgment by management about matters that are, by nature, uncertain is required to record a deferred tax asset and establish a valuation allowance.
In evaluating the need for a valuation allowance, Busey estimates future taxable income based on management forecasts and tax planning strategies that may be available to the Company.
First Busey Corporation (BUSE) | 2024 — 43

Table of Contents Contents of Item 1A. Risk Factors
While Busey has determined that no valuation allowance is currently required for any deferred tax assets, if future events differ significantly from current forecasts, the Company may need to establish a valuation allowance against its net deferred tax assets, which would have a material adverse effect on its results of operations and financial condition. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods prior to the expiration of the related net operating losses and may be limited by Section 382 of the Internal Revenue Code.
Investments in tax-advantaged projects may not generate returns as anticipated and may have an adverse impact on Busey’s financial results.
Busey invests in certain tax-advantaged projects promoting affordable housing, community development, and other community revitalization projects. These investments are designed to generate a return primarily through the realization of federal and state income tax credits and other tax benefits over specified periods. Busey is subject to the risk that previously recorded tax credits, which remain subject to recapture by taxing authorities based on compliance features required at the project level, may fail to meet certain government compliance requirements and may not be realized.
The potential inability to realize these tax credits and other tax benefits could negatively impact Busey’s financial results. The ultimate realization of these benefits depends upon having sufficient taxable income and on many other factors outside of Busey’s control, including changes in the applicable tax code and the ability of the projects to be completed. Busey continues to monitor tax law developments and compliance with applicable regulations to mitigate these risks.
OPERATIONAL RISKS
Busey’s framework for managing risks may not be fully effective in mitigating risk and loss.
Busey’s risk management framework is designed to identify, measure, monitor, and analyze a broad spectrum of risks, including compliance, operational, and reputational risks. However, as with any framework, inherent limitations exist, particularly as new risks emerge or previously unidentified vulnerabilities become apparent.
The effectiveness of this framework depends on its alignment with Busey’s evolving risk profile, especially in light of the planned CrossFirst merger. As the organization grows in complexity, risks related to integration, system coordination, and operational oversight may challenge the framework's capacity to adapt. Failures to effectively manage these risks could adversely impact Busey’s financial condition, regulatory standing, and overall operational stability.
To address these challenges, Busey continuously refines its processes, leveraging advanced risk assessment tools and seeking alignment with industry best practices. Despite these efforts, no risk management framework is foolproof, and unforeseen losses or disruptions remain a possibility.
Technological investments drive efficiency but introduce cybersecurity risks.
Busey’s ongoing investments in technology infrastructure have strengthened operational efficiency, enhanced client service delivery, and supported the scaling of key business functions. Initiatives such as enterprise-wide automation, cloud integration, and enhanced data analytics capabilities have positioned Busey as a forward-thinking financial institution. However, these advancements introduce vulnerabilities, including the risk of cyber-attacks and operational disruptions.
The Federal Reserve’s November 2024 Financial Stability Report has emphasized growing threats posed by sophisticated cyber-attacks. These threats not only compromise data integrity but also pose significant reputational and financial risks. For example:
First Busey Corporation (BUSE) | 2024 — 44

Table of Contents Contents of Item 1A. Risk Factors
•Supply Chain Risk Amplification: Third-party vendors and their subcontractors introduce multi-layered risks, complicating oversight and heightening the likelihood of service interruptions or compliance breaches.
•Advanced Cyber Threats: As bad actors deploy increasingly sophisticated tactics, including artificial intelligence-driven impersonation and malware, the effectiveness of traditional cybersecurity defenses is diminished.
To mitigate these risks, Busey has implemented robust cybersecurity protocols, regular system audits, and incident response plans. The use of artificial intelligence-powered tools, such as Verafin, provide additional layers of fraud detection, enabling proactive threat management. However, as cybersecurity threats evolve, the possibility of system penetration persists even with robust security protocols in place.
Outsourcing dependencies could disrupt operations and increase compliance risks.
Busey’s reliance on secure and resilient systems to manage customer relationships, transactions, and data underscores the critical importance of operational stability. Outsourcing arrangements introduce risks tied to service disruptions, compliance violations, and vulnerabilities stemming from subcontractors in downstream supply chains.
This cascading outsourcing structure adds complexity to communication and coordination, particularly when vendors operate in regions with varying regulatory standards. Risks are further amplified by geopolitical tensions, trade restrictions, or cyberattacks targeting these external partners.
Failures or breaches in these systems could disrupt Busey’s operations, damage its reputation, or result in significant legal exposure. While Busey conducts rigorous due diligence when selecting third-party providers, residual risks from subsequent outsourcing tiers remain challenging to eliminate entirely.
Fraudulent activities could erode financial stability and customer trust.
The rising sophistication of fraudulent schemes poses a persistent challenge for financial institutions, with Busey being no exception. Fraudulent activities, such as identity theft, phishing, and unauthorized transactions, could result in financial losses, regulatory penalties, and erosion of customer trust.
Busey employs a multi-layered approach to fraud prevention, including internal controls, insurance coverage, and advanced fraud detection tools, like Verafin. However, even robust frameworks may not fully eliminate risks, particularly as threat actors adapt their tactics to exploit emerging vulnerabilities.
Busey’s ability to attract and retain key personnel may affect future growth and earnings.
Busey’s ability to attract and retain experienced management and qualified personnel is critical to sustaining growth and executing its strategic objectives. The leadership transitions associated with the CrossFirst merger highlight the importance of talent management in preserving operational continuity.
In addition to retaining key leaders, Busey’s ability to build a diverse and skilled workforce is essential to implementing its community-based strategy effectively. The unexpected departure of high-performing employees or difficulty in recruiting specialized talent could disrupt operations, delay strategic initiatives, or increase costs associated with workforce realignment.
First Busey Corporation (BUSE) | 2024 — 45

Table of Contents Contents of Item 1A. Risk Factors
Damage resulting from negative publicity could harm Busey’s reputation and adversely impact its business and financial condition.
Busey’s ability to attract and retain customers, investors, and employees is contingent upon maintaining trust. Negative public opinion could result from the Company’s actual or alleged conduct in a number of activities, including, but not limited to, employee misconduct, failure or perceived failure to deliver appropriate standards of service and quality, faulty lending practices, compliance failures, security breaches, corporate governance, sharing or inadequate protection of customer information, failure to comply with laws or regulations, and actions taken by government regulators and community organizations in response to that conduct.
The CrossFirst merger further underscores the importance of preserving a positive reputation during this period of transformation. Mergers often attract heightened scrutiny from regulators, investors, and the public, amplifying the potential for reputational risks. Missteps in integration, such as service disruptions, a perceived decline in quality, or employee dissatisfaction could adversely impact public perception.
The results of such actual or alleged misconduct or missteps could include customer dissatisfaction, inability to attract potential acquisition prospects, litigation, and heightened regulatory scrutiny. These outcomes may lead to lost revenue, higher operating costs, and harm to Busey’s reputation. Despite the cost or efforts made by the Company to address issues arising from reputational harm, there is no assurance that these efforts could fully mitigate adverse impacts on Busey’s business, financial condition, and results of operations.
Rapid adoption of generative artificial intelligence technologies introduces operational vulnerabilities.
The rapid adoption of generative artificial intelligence technologies introduces a range of operational risks, including intellectual property disputes, compliance challenges, and data privacy concerns. The use of artificial intelligence in fraud schemes, such as impersonation attacks and social engineering, underscores the urgency of proactive governance.
Busey remains committed to addressing these risks through advanced technological tools, regular assessments, and collaboration with industry peers to stay ahead of evolving threats.
ITEM 1B. UNRESOLVED STAFF COMMENTS
None.
ITEM 1C. CYBERSECURITY
Busey maintains a cyber security risk management program designed to prevent, detect, and respond to information security threats. The program is designed to align with the Cyber Risk Institute’s Profile framework, which is based on the National Institute of Standards and Technology’s Cybersecurity Framework. The program is led by Busey’s Chief Information Security Officer (“CISO”). Busey’s CISO has been in the role since September 2020 and has over 15 years of experience across external and internal audit, technology risk management, and cybersecurity matters, spanning various industries primarily within the financial services sector, but also including healthcare, technology, consumer products, and manufacturing for both regional and multinational corporations. Busey’s cyber security risk management program is a key part of the Company’s overall risk management system, which is administered by the Chief Risk Officer.
Busey’s cyber security risk management program includes administrative, technical, and physical safeguards to help ensure the security and confidentiality of customer records and information. Busey has long devoted significant resources to assessing, identifying, and managing risks associated with cybersecurity threats, including:
•Establishing an internal cybersecurity team that is responsible for conducting regular assessments of Busey’s information systems, existing controls, vulnerabilities, and potential improvements;
First Busey Corporation (BUSE) | 2024 — 46

Table of Contents
•Employing continuous monitoring tools that can detect and help respond to cybersecurity threats in real-time;
•Performing due diligence with respect to third-party service providers, including their cybersecurity practices, and requiring contractual commitments from Busey’s service providers to take certain cybersecurity measures;
•Ongoing monitoring and assessment of third-party vendors' cybersecurity practices, including regular audits, compliance checks, and incident reporting requirements;
•Engaging third-party cybersecurity consultants, who conduct periodic penetration testing, vulnerability assessments, and other procedures to identify potential weaknesses in Busey’s systems and processes;
•Mandating periodic cybersecurity training for Busey’s workforce, which includes awareness programs on phishing, social engineering, and other common cyber threats;
•Implementing access control measures such as multi-factor authentication, role-based access controls, and regular access reviews to ensure that only authorized personnel have access to critical systems and data;
•Using data encryption for both data at rest and data in transit to protect sensitive information; and
•Creating an incident response plan that outlines the steps to contain, mitigate, and remediate the impact of cybersecurity incidents, including communication protocols and post-incident analysis.
Busey’s security and privacy policies and procedures are in effect across all of its businesses and geographic locations. Busey adheres to various regulatory requirements and standards, including the Gramm-Leach-Bliley Act to ensure compliance with data protection laws. Additionally, Busey maintains cybersecurity insurance coverage to mitigate potential financial impacts from cyber incidents.
Busey’s board of directors, as a whole and through its Enterprise Risk Committee (the “Risk Committee”), is responsible for the oversight of risk management. In that role, Busey’s board of directors and Risk Committee, with support from Busey’s cybersecurity advisors, are responsible for ensuring that the risk management processes developed and implemented by management are adequate and functioning as designed. To carry out those duties, both the board of directors and the Risk Committee receive quarterly reports from Busey’s management team regarding cybersecurity risks, and Busey’s efforts to prevent, detect, mitigate, and remediate any cybersecurity incidents.
Busey’s historical data indicates that while Busey has encountered cybersecurity threats and incidents, none have materially affected the Company. Still, Busey faces a number of cybersecurity risks in connection with its business, and it is possible that threats and incidents identified in the future could have a material adverse effect on Busey’s business strategy, results of operations, and financial condition. For additional information on the risks that cybersecurity threats pose to Busey see “Item 1A. Risk Factors—Operational Risks.”

ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED STOCKHOLDER MATTERS, AND ISSUER PURCHASES OF EQUITY SECURITIES
COMMON STOCK
Busey’s common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.”
Busey’s board of directors and management are currently committed to continue paying regular cash dividends; however, no guarantee can be given with respect to future dividends, as they are dependent on certain regulatory restrictions, future earnings, capital requirements, and the financial condition of First Busey Corporation and its subsidiaries. See “Item 1. Business—Supervision, Regulation, and Other Factors—Supervision and Regulation of First Busey Corporation—Dividend Payments” and “Item 1. Business—Supervision, Regulation, and Other Factors—Supervision and Regulation of Busey Bank—Dividend Payments” for further discussion of these matters.
As of February 27, 2025, First Busey Corporation had 56,958,853 shares of common stock outstanding held by 1,766 holders of record. Additionally, there were an estimated 14,297 beneficial holders whose stock was held in street name by brokerage houses and nominees as of that date.
STOCK REPURCHASE PLAN
On February 3, 2015, First Busey Corporation's board of directors approved the Stock Repurchase Plan to enable Busey to purchase shares of its common stock through various means including purchases executed on the open market, through block trades or otherwise, and in privately negotiated transactions. The Stock Repurchase Plan provides Busey with treasury shares from which stock-based compensation can be issued, and it limits the number of outstanding shares that may be actively traded. The Stock Repurchase Plan does not obligate Busey to purchase any shares of its common stock, and has no expiration date. The Stock Repurchase Plan may be terminated, or the number of shares authorized for repurchase may be increased or decreased by Busey's board of directors at its discretion at any time.
Under the Stock Repurchase Plan, Busey's board of directors has authorized shares for repurchase as shown in the table below:

| Number of Shares Authorized
February 3, 2015 | 666,667
May 22, 2019 | 1,000,000
February 5, 2020 | 2,000,000
May 24, 2023 | 2,000,000

During the fourth quarter of 2024, Busey purchased no shares of its common stock pursuant to the Stock Repurchase Plan. As of December 31, 2024, Busey had 1,919,275 shares that may still be purchased under the Stock Repurchase Plan.

SCOPE OF DISCUSSION
The following is management’s discussion and analysis of the financial condition as of December 31, 2024, and 2023, and the results of operations for the years ended December 31, 2024, 2023, and 2022, of First Busey Corporation and its subsidiaries. It should be read in conjunction with “Item 1. Business,” the Consolidated Financial Statements, and the related Notes to the Consolidated Financial Statements included in this Annual Report.
Detailed discussion and analysis of Busey’s financial condition and results of operation for 2024 as compared to 2023 can be found below. Comparison of 2023 to 2022 can be found in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of Busey's 2023 Annual Report.
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 1 funded, with robust liquidity and significant market share in the communities Busey serves. As of December 31, 2024, Busey’s loan to deposit ratio was 77.1% and core deposits 1 represented 96.5% 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. As a result, 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, 2024, Busey’s leverage ratio of Tier 1 capital to average assets was 11.1%, its common equity Tier 1 capital to risk weighted assets ratio was 14.1%, and its total capital to risk weighted assets ratio was 18.5%.
Busey executed a two-part balance sheet repositioning strategy in 2024
During the first quarter of 2024, Busey sold the mortgage servicing rights on approximately $923.5 million of one- to four-family mortgage loans for a pre-tax gain of $7.7 million, which enabled Busey to sell available-for-sale investment securities with a book value of approximately $108.2 million for a pre-tax loss of $6.8 million with no resulting negative impact to tangible capital. At the time of the sale, the securities sold yielded a weighted average rate of 1.98% and had a weighted-average life of 2.3 years.
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.
1 Core deposits is a non-GAAP financial measure. For a reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures, see “Item 1. Business—Non-GAAP Financial Information.”
First Busey Corporation (BUSE) | 2024 — 52

Table of Contents Contents of Item 7. MD&A
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 judgement 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 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 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.

1. Acquisition expenses in 2024 were related to the acquisition of M&M, which was completed on April 1, 2024, as well as the planned merger with CrossFirst. For 2023, acquisition expenses were related to the then planned acquisition of M&M, as well as to exploratory costs. For 2022, acquisition expenses related to the integration of Cummins-American Corp. and its wholly-owned subsidiary, Glenview State Bank, following completion of this acquisition in 2021, as well as to exploratory costs.
2. Restructuring expenses were related to previously disclosed restructuring and efficiency plans and to corporate strategy advisement.
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 Annual Report. See “Item 1. Business—Non-GAAP Financial Information.”
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.
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.
Consolidated Average Balance Sheets and Interest Rates
The table below presents Busey’s Consolidated Average Balance Sheets, detailing average balances for each major category of assets and liabilities, the interest income earned on interest-earning assets, the interest expense paid for interest-bearing liabilities, and the related interest yields for the periods indicated.

After raising federal funds rates by a total of 525 bps between March 2022 and July 2023, the FOMC lowered rates by 100 bps beginning in September 2024. During 2024, in anticipation of the FOMC pivot to an easing cycle, Busey limited its exposure to term funding structures and intentionally priced savings specials to encourage maturing CD balances to migrate to managed rate non-maturity products. Beginning in September 2024 Busey began lowering rates on special priced deposit accounts and other managed rate products to benefit from the FOMC rate cuts. Busey continues to offer CD specials with shorter term structures as well as offering attractive premium savings rates to encourage rotation of maturing CD deposits into nimble pricing products. Beginning in the second quarter of 2024, Busey also saw the full benefit of the December 2023 and March 2024 targeted balance sheet repositioning in its net interest margin.
Net interest spread represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, and is presented in the table below for the periods indicated:

Total noninterest income was $139.7 million for the year ended December 31, 2024, an increase of 15.2% when compared with $121.2 million for the year ended December 31, 2023. Total noninterest income represented 30.2% of total revenue 2 in 2024, compared to 27.4% in 2023.
Wealth management fees increased by 11.0% to $63.6 million in 2024, compared to $57.3 million in 2023. Busey’s Wealth Management division had $13.83 billion in assets under care as of December 31, 2024, compared to $12.14 billion as of December 31, 2023. Busey’s portfolio management team continues to focus on long-term returns and managing risk in the face of volatile markets.
Payment technology solutions revenue relates to Busey’s payment processing company, FirsTech. Payment technology solutions revenue increased by 3.7% to $22.0 million in 2024, compared to $21.2 million in 2023. Results for 2024 marked a new record high reported annual revenue for FirsTech.
Combined, revenues from wealth management fees and payment technology solutions represented 61.3% and 64.8% of Busey’s noninterest income for the years ended December 31, 2024, and December 31, 2023, respectively, providing a complement to spread-based revenue from traditional banking activities. On a combined basis, revenue from these two critical operating areas was $85.6 million for the year ended December 31, 2024, a 9.1% increase from $78.5 million for the year ended December 31, 2023.
Fees for customer services increased by 6.5% to $30.9 million in 2024, compared to $29.0 million in 2023.
Mortgage revenue was $2.1 million in 2024, compared to $1.1 million in 2023. Increases were primarily related to sold-loan mortgage volume. General economic conditions and interest rate volatility may impact future mortgage revenue.
Income on bank owned life insurance increased by 9.1% to $5.1 million in 2024, compared to $4.7 million in 2023, resulting from a $0.1 million increase in earnings on death proceeds and a $0.3 million increase in the cash surrender value of the insurance policies.
A realized gain on the sale of mortgage servicing rights of $7.7 million was recognized in connection with Busey’s strategic two-part balance sheet repositioning completed during 2024. Busey sold the mortgage servicing rights on approximately $923.5 million of one- to four-family mortgage loans, which enabled Busey to sell available for sale investment securities with a book value of approximately $108.2 million for a pre-tax loss of $6.8 million with no resulting negative impact to tangible capital.
Other income increased by 42.0% to $14.3 million in 2024, compared to $10.1 million in 2023. Increases in other income were primarily attributable to increases in commercial loan sales gains and venture capital income, as well as the addition of Life Equity Loan® servicing income beginning in the second quarter of 2024.
2 Total revenue consists of net interest income plus noninterest income.

Total noninterest expense increased to $300.4 million for the year ended December 31, 2024, compared to $285.5 million for the year ended December 31, 2023, representing a year-over-year increase of 5.2%. Non-operating acquisition and other restructuring expenses increased to $8.1 million in 2024, compared to $4.3 million in 2023. The remaining increases can be attributed primarily to operating M&M Bank as a stand-alone bank from April 1, 2024, through June 21, 2024, and general inflationary pressures on compensation and benefits and to a lesser extent certain other expense categories. Busey expects to continue to prudently manage its expenses and to realize the full extent of M&M acquisition synergies in 2025.

Table of Contents Contents of Item 7. MD&A
Salaries, wages, and employee benefits increased to $175.6 million in 2024, compared to $162.6 million in 2023. Busey’s total associate base consisted of 1,509 full-time equivalents as of December 31, 2024, compared to 1,479 at December 31, 2023, with the increase largely relating to the M&M acquisition. Busey recorded $1.6 million and $3.8 million of non-operating expenses during 2024 and 2023, respectively. Current trends continue to reflect a competitive labor market, maintaining pressure on costs related to attracting and maintaining Busey’s skilled workforce.
Data processing expense increased to $27.1 million in 2024, compared to $23.7 million in 2023. Increases were primarily attributable to Company-wide investments in technology enhancements, as well as inflation-driven price increases.
Combined, net occupancy expense of premises and furniture and equipment expenses increased to $25.5 million in 2024, compared to $25.0 million in 2023. Primary cost drivers in these expense categories include lease costs, repairs and maintenance, depreciation expense, real estate taxes, and utilities.
Professional fees increased to $12.8 million in 2024, compared to $7.1 million in 2023. Busey recorded $4.9 million and $0.4 million of non-operating expenses during 2024 and 2023, respectively. The significant increase in non-operating professional fees related primarily to the acquisition of M&M, which was completed in the second quarter of 2024, and the planned merger with CrossFirst, which is expected to be completed in the first quarter of 2025.
Amortization of intangible assets decreased to $10.1 million in 2024, compared to $10.4 million in 2023. Decreases in 2024 were due to the use of an accelerated amortization methodology and were partially offset by the addition of $6.3 million of intangible assets related to the M&M acquisition.
Interchange expense decreased to $6.0 million in 2024, compared to $6.9 million in 2023. Fluctuations in interchange expense relate to payment and volume activity at FirsTech.
FDIC insurance expense decreased to $5.6 million in 2024, compared to $5.7 million in 2023.
Other expense decreased to $37.6 million in 2024, compared to $44.2 million in 2023. In connection with Busey’s adoption of ASU 2023-02 on January 1, 2024, Busey began recording amortization of New Markets Tax Credits as income tax expense instead of other noninterest expense, resulting in decreases in other noninterest expense of $9.0 million for the year ended December 31, 2024. Further changes in other noninterest expense are attributable to multiple items, including the provision for unfunded commitments, sales of other real estate owned, fixed asset impairment, marketing, and business development expenses.
Efficiency Ratio
The efficiency ratio 3 is calculated as total noninterest expense, less amortization charges, as a percentage of tax-equivalent net interest income plus noninterest income, less security gains and losses. The efficiency ratio, 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 61.8% for the year ended December 31, 2024, compared to 61.7% for the year ended December 31, 2023.
Operating costs have been influenced by acquisition expenses and other restructuring costs, and the adjusted efficiency ratio 3 was 61.0% for the year ended December 31, 2024, compared to 60.7% for the year ended December 31, 2023.
3 The efficiency ratio and adjusted efficiency ratio are both non-GAAP financial measures. For a reconciliation of non-GAAP financial measures to the most directly comparable GAAP financial measures, see “Item 1. Business—Non-GAAP Financial Information.”

Income Taxes
Effective income tax rates, calculated by dividing income taxes by income before taxes, were 25.8%, 20.4%, and 20.7% for the years ended December 31, 2024, 2023, and 2022, respectively. Busey’s effective tax rates increased in 2024 due to the adoption of ASU 2023-02 in January 2024, yet remained lower than the combined federal and state statutory rate of approximately 28.0% due to tax exempt interest income, such as municipal bond interest and bank owned life insurance income.
Busey’s effective income tax rate for the year ended December 31, 2024, includes an estimated one-time deferred tax valuation adjustment of $1.4 million resulting from a change to the Illinois apportionment rate due to recently enacted regulations. These new regulations are expected to lower Busey’s ongoing tax obligation in future periods.
Busey continues to monitor evolving federal and state tax legislation and its potential impact on operations on an ongoing basis. As of December 31, 2024, Busey Bank is under examination by the Florida Department of Revenue for its 2020 to 2022 corporate income tax filings. Further, in February of 2025, Busey received a notice of audit initiation from the Illinois Department of Revenue for M&M’s tax filings for the tax years 2022 and 2023.

Investment Securities
The primary purposes of Busey’s investment securities portfolio are to provide a source of earnings by deploying funds that are not needed to fulfill loan demand, deposit redemptions, or other liquidity purposes; to serve as a tool for interest rate risk positioning; and to provide collateral for pledging purposes against public deposits and repurchase agreements, all while providing a source of liquidity.
Busey considers many factors in determining the composition of its investment portfolio including, but not limited to, credit quality, duration, interest rate risk, liquidity, tax-equivalent yield, regulatory considerations, and overall portfolio allocation. As of December 31, 2024, Busey did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of Busey’s stockholders’ equity.
Pledged securities totaled $871.4 million, or 33.0% of total debt securities, as of December 31, 2024, and $837.4 million, or 28.3% of total debt securities, as of December 31, 2023.
Debt Securities Available for Sale
Debt securities available for sale are carried at fair value. Net unrealized gains or losses, net of tax, are recorded in stockholders’ equity, through AOCI. As of December 31, 2024, the fair value of debt securities available for sale was $1.81 billion, and the amortized cost was $2.04 billion. There were $0.6 million of gross unrealized gains and $230.3 million of gross unrealized losses, resulting in a net unrealized loss of $229.7 million.

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. M&M’s policies were similar in nature to Busey Bank’s policies, and Busey is in the process of migrating the legacy M&M portfolio toward Busey Bank’s policies. 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. Loans originated outside of these areas are generally to existing customers of Busey Bank. Busey attempts 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.
C&I and Other Commercial Loans
C&I and other commercial loans typically comprise working capital loans or business expansion loans, including loans for asset purchases and other business loans. C&I and other commercial loans will generally be guaranteed, in full or a material percentage, by the primary owners of the business. C&I and other commercial loans are made based primarily on the borrower’s historical and projected cash flows and secondarily on the underlying assets pledged as collateral by the borrower. Cash flows of the borrower, however, may not perform consistently with historical or projected information. Further, collateral securing loans may fluctuate in value due to individual economic or other factors. Busey Bank has established minimum standards and underwriting guidelines for all C&I and other commercial loan types.

Table of Contents Contents of Item 7. MD&A
Commercial Real Estate Loans
The commercial environment, along with the academic presence in some of the markets in which Busey operates, provides for the majority of Busey’s commercial lending opportunities to be CRE related, including multi-unit housing. As the majority of Busey’s loan portfolio is within the CRE class, Busey’s goal is to maintain a high quality, geographically diverse portfolio of CRE loans. CRE loans are subject to underwriting standards and guidelines similar to commercial loans. CRE loans are generally guaranteed, in full or a material percentage, by the primary owners of the business. Repayment of these loans is primarily dependent on the cash flows of the underlying property. However, CRE loans generally must be supported by an adequate underlying collateral value. The performance and the value of the underlying property may be adversely affected by economic factors or geographical and/or industry specific factors. These loans are subject to other industry guidelines which Busey closely monitors.
Real Estate Construction Loans
Real estate construction loans are primarily commercial in nature. Loan proceeds are monitored by Busey and advanced for the improvement of real estate in which Busey holds a mortgage. Real estate construction loans will generally be guaranteed, in full or a material percentage, by the developer or primary owners of the business. These loans are subject to underwriting standards and guidelines similar to commercial loans. The loan generally must be supported by an adequate “as completed” value of the underlying project. In addition to the underlying project, the financial history of the developer and business owners weighs significantly in determining approval. Repayment of these loans is typically through permanent financing following completion of the construction. Real estate construction loans are inherently more risky than loans on completed properties as the unimproved nature and the financial risks of construction significantly enhance the risks of commercial real estate loans. These loans are closely monitored and subject to other industry guidelines.
Retail Real Estate Loans
Retail real estate loans are comprised of direct consumer loans that include residential real estate, home equity lines of credit, and home equity loans. In 2024, Busey retained a smaller percentage of originated retail real estate loans in its portfolio, electing to sell a larger percentage to secondary market purchasers. As retail real estate loan underwriting is subject to specific regulations, Busey typically underwrites retail real estate loans to conform to widely accepted standards. Several factors are considered in underwriting including the debt-to-income ratio and credit history of the borrower, as well as the value of the underlying real estate.
Retail Other Loans
Retail other loans consist of installment loans to individuals, including automotive loans and indirect lending. These loans are centrally underwritten utilizing the borrower’s financial history, including credit scores, as well as information about the underlying collateral. Retail other loans also include whole-life loans which are secured by the cash value of underlying life insurance policies. Repayment of retail other loans is expected from the borrower’s cash flows.

Portfolio loan growth in 2024 was due to the M&M acquisition. As has been Busey’s practice, the Company remains steadfast in its conservative approach to underwriting and disciplined approach to pricing, particularly given Busey’s outlook for the economy in the coming quarters. This posture will continue to impact loan growth, which Busey expects to remain modest over the next several quarters.
Concentration of Credit Risk
As a matter of policy and practice, Busey limits the level of concentration exposure in any particular loan segment with the goal of maintaining a well-diversified loan portfolio. The following table presents the percentage of total portfolio loans for each lending activity.

Allowance and Provision for Credit Losses
The ACL is a significant estimate on Busey’s 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 expenses (releases) were recorded as follows for each of the years indicated (dollars in thousands):

Busey did not record an allowance for credit loss for its Life Equity Loan® portfolio, a component of its retail other lending activity, due to no expected credit loss at default, as permitted under the practical expedient provided within ASC 326-20-35-6. The Life Equity Loan® portfolio balance was $264.2 million as of December 31, 2024.
The ongoing impacts of CECL will be dependent upon changes in economic conditions and forecasts, originated and acquired loan portfolio composition, credit performance trends, portfolio duration, and other factors. As of December 31, 2024, Busey management believed the level of the allowance to be appropriate based upon the information available. However, additional losses may be identified in the loan portfolio as new information is obtained.
Non-Performing Loans and Non-Performing Assets
Loans are considered past due if the required principal or interest payments have not been received as of the date such payments were due. Loans are placed on non-accrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due, as well as when required by regulatory guidelines. Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due. Loans are returned to accrual status when all principal and interest amounts contractually due are brought current and future payments are reasonably assured.
Typically, loans are secured by collateral. When a loan is classified as non-accrual and determined to be collateral dependent, it is appropriately reserved or charged down through the ACL to the fair value of Busey’s interest in the underlying collateral less estimated costs to sell. Busey’s loan portfolio is collateralized primarily by real estate.

Asset quality remains strong by both Busey’s historical and current industry trends, and Busey’s operating mandate and focus have been on emphasizing credit quality over asset growth.
Non-performing loan balances increased by 197.30% to $23.2 million as of December 31, 2024, compared to $7.8 million as of December 31, 2023. The increase was primarily related to one CRE loan that was classified in the fourth quarter of 2023 and was moved to non-accrual during the fourth quarter of 2024. This loan carries a remaining balance of $15.0 million following a $3.0 million charge-off in the fourth quarter of 2024. Non-performing loans represented 0.30% of portfolio loans as of December 31, 2024, compared to 0.10% as of December 31, 2023. Busey’s ACL coverage decreased to 3.59 times its non-performing loan balance at December 31, 2024, compared to 11.74 times its non-performing loan balance at December 31, 2023.

Non-performing assets, which includes non-performing loans, OREO, and other repossessed assets, increased by 193.41% to $23.3 million as of December 31, 2024, compared to $7.9 million as of December 31, 2023. Non-performing assets represented 0.19% of total assets as of December 31, 2024, compared to 0.06% as of December 31, 2023. Busey’s ACL provided coverage of 3.58 times its non-performing assets at December 31, 2024, down from 11.55 times its non-performing assets at December 31, 2023.
Classified assets, which include non-performing assets and substandard loans, increased to $85.3 million as of December 31, 2024, compared to $72.3 million as of December 31, 2023. Classified assets represented 5.61% of Busey Bank’s Tier 1 capital and ACL at December 31, 2024, up from 4.97% at December 31, 2023.
Net charge-offs totaled $18.2 million in 2024, representing 0.23% of average loans, compared with net charge-offs of $2.3 million in 2023, representing 0.03% of average loans. Increases in net charge-offs during the year ended December 31, 2024, were significantly attributable to a single C&I credit relationship and the CRE loan relationship mentioned above.
Asset quality metrics remain dependent upon market-specific economic conditions, and specific measures may fluctuate from period to period. If economic conditions were to deteriorate, Busey would expect the credit quality of its loan portfolio to decline and loan defaults to increase.
Potential Problem Loans
Potential problem loans are loans classified as substandard which are not individually evaluated, non-accrual, or 90+ days past due, but where current information indicates that the borrower may not be able to comply with loan repayment terms. Management assesses the potential for loss on such loans and considers the effect of any potential loss in determining its provision for expected credit losses. Potential problem loans decreased to $62.0 million at December 31, 2024, compared to $64.3 million at December 31, 2023. Management continues to monitor these loans and work with the borrowers on restructurings, guarantees, additional collateral, or other planned actions. As of December 31, 2024, 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.

Total deposits decreased by 3.0% to $9.98 billion as of December 31, 2024, compared to $10.29 billion as of December 31, 2023. The quality of Busey’s core deposit 4 franchise coupled with cash flows from its securities portfolio allows Busey to fund loan growth while limiting its reliance on higher cost wholesale funding alternatives. Busey focuses on deepening its customer relationships to maintain and protect its strong core deposit franchise. As of December 31, 2024, Busey average customer tenure was 16.9 years for retail customers and 12.8 years for commercial customers. Core deposits include non-brokered transaction accounts, money market and savings deposit accounts, and time deposits of $250,000 or less. Core deposits represented 96.5% of total deposits as of December 31, 2024, compared to 96.2% as of December 31, 2023.
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 $3.78 billion at December 31, 2024. The portion of Busey’s deposit base that was uninsured and not otherwise collateralized was estimated to be $2.96 billion at December 31, 2024, which represented 30% of total deposits. Of that amount, $286.4 million represented time deposits. The following table presents estimates of the uninsured portion of time deposits by maturity date (dollars in thousands):

| As of December 31, 2024
Estimated uninsured time deposits by schedule of maturities |
3 months or less | $ | 107,163 |

Borrowings
Term Loan
On May 28, 2021, Busey entered into a Second Amended and Restated Credit Agreement, pursuant to which it has access to (1) a $40.0 million revolving line of credit with an initial termination date of April 30, 2022, and (2) a $60.0 million Term Loan with a maturity date of May 31, 2026. The loans had an annual interest rate of 1.75% plus the one-month LIBOR rate. On April 30, 2022, the agreement was amended, effecting an extension of the termination date for the revolving line of credit to April 30, 2023, and providing for the transition from a LIBOR-indexed interest rate to a SOFR-indexed interest rate. Under the terms of the amendment, the annual interest rate for the loans was established at 1.80% plus the one-month forward-looking term rate based on SOFR. The agreement has subsequently been amended twice to extend the termination date for the revolving line of credit, which is currently April 30, 2025.
During the first quarter of 2024, Busey paid the full $30.0 million balance remaining on the Term Loan, at which time the Term Loan carried interest at a rate of 7.13%. As of December 31, 2024, there was no balance outstanding on the revolving credit facility. The revolving credit facility incurs a non-usage fee based on any undrawn amounts.
Short-term Borrowings and Securities Sold Under Agreements to Repurchase
Short-term borrowings include FHLB advances that mature in less than one year from the date of origination, and the current portion of long-term debt due within 12 months. Securities sold under agreements to repurchase, which are classified as secured borrowings, generally mature daily.

Subordinated Notes
On June 1, 2020, Busey issued $125.0 million of fixed-to-floating rate subordinated notes that mature on June 1, 2030. The subordinated notes, which qualify as Tier 2 capital for regulatory purposes, bear interest at an annual rate of 5.25% for the first five years after issuance and thereafter 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. Interest on the subordinated notes is payable semi-annually on each June 1 and December 1 during the five-year fixed-term, and thereafter on March 1, June 1, September 1, and December 1 of each year, commencing on September 1, 2025. The subordinated notes have an optional redemption in whole or in part on any interest payment date on or after June 1, 2025. The subordinated notes are unsecured obligations of the Company.
First Busey Corporation (BUSE) | 2024 — 81

Table of Contents Contents of Item 7. MD&A
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 expected to be 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 “Note 2. Mergers and Acquisitions”), Busey acquired $4.0 million of 5.25% fixed-to-floating rate subordinated notes maturing December 4, 2030, which qualify as Tier 2 capital for regulatory purposes. Interest on the subordinated notes 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 expected to be the Three-Month Term SOFR (as defined in the subordinated notes), plus a spread of 497 bps from December 4, 2025. The subordinated notes have an optional redemption, in whole or in part, on or after December 4, 2025. At December 31, 2024, there was $0.1 million of fair value discount outstanding, to be accreted through the earliest optional redemption date.

Junior Subordinated Debt Owed to Unconsolidated Trusts
Busey maintains statutory trusts for the sole purpose of issuing and servicing trust preferred securities and related trust common securities. Proceeds from such issuances were used by the trusts to purchase junior subordinated notes of Busey, which are the sole assets of each trust. Concurrent with the issuance of the trust preferred securities, Busey issued guarantees for the benefit of the holders of the trust preferred securities. The trust preferred securities are instruments that qualify, and are treated, as Tier 1 regulatory capital. Busey owns all of the common securities of each trust. The trust preferred securities issued by each trust rank equally with the common securities in right of payment, except that if an event of default under the indenture governing the notes has occurred and is continuing, the preferred securities will rank senior to the common securities in right of payment. Busey had $74.8 million and $72.0 million of junior subordinated debt owed to unconsolidated trusts at December 31, 2024, and 2023, respectively. In connection with its acquisitions of Pulaski Financial Corp. in 2016 and M&M in 2024, Busey has acquired similar statutory trusts and the fair value adjustment is being accreted over their weighted average remaining lives, with a balance remaining to be accreted of $2.9 million and $2.6 million at December 31, 2024, and 2023, respectively.

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 (dollars in thousands):

Table of Contents Contents of Item 7. MD&A
As of December 31, 2024, 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.
Busey’s ability to pay cash dividends to its stockholders and to service its debt is dependent on the receipt of cash dividends from its subsidiaries. Busey Bank paid dividends to First Busey Corporation totaling $100.0 million and $90.0 million for the years ended December 31, 2024, and 2023, respectively.
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 (dollars in thousands):

| As of December 31,
| 2024 |  | 2023
Outstanding loan commitments and standby letters of credit | $ | 2,548,178 |  |  | $ | 2,176,496 |
Reserve for unfunded commitments | 5,967 |  |  | 7,062 |

The following table summarizes Busey’s provision for unfunded commitments expenses (releases) for the periods presented (dollars in thousands):

Provision for unfunded commitments expense (release) | Other noninterest expense |  | $ | (1,095) |  |  | $ | 461 |  |  | $ | 61 |

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.
Contractual Obligations
Busey has entered into certain contractual obligations and other commitments that generally relate to funding of operations through deposits, debt issuance, and property and equipment leases.

Cash Flows
Busey’s cash flows consist of operating activities, investing activities, and financing activities.
Net cash flows provided by operating activities totaled $178.3 million in 2024, compared to $173.4 million provided by operating activities in 2023. Significant operating activities affecting cash flows include net income, depreciation and amortization, the provision for credit losses, stock-based compensation, and mortgage loan sale activity. Fluctuations in sales of loans held for sale are a function of changes in market rates for mortgage loans, which influence refinance activity.
Net cash provided by investing activities totaled $657.9 million in 2024, compared to $551.0 million provided by investing activities in 2023. Significant investing activities are those associated with managing Busey’s investment and loan portfolios.
Net cash used in financing activities totaled $858.1 million in 2024, compared to $232.0 million used in financing activities in 2023. Significant financing activities affecting cash flows include deposit and other borrowings, as well as cash dividends paid.
For additional detail, see the Consolidated Statements of Cash Flows.

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 Busey Bank as of December 31, 2024.

| Minimum Capital Requirements with Capital Buffer |  | As of December 31, 2024
|  | First Busey |  | Busey Bank
Common Equity Tier 1 Capital to Risk Weighted Assets | 7.00 | % |  | 14.10 | % |  | 16.46 | %
Tier 1 Capital to Risk Weighted Assets | 8.50 | % |  | 14.98 | % |  | 16.46 | %
Total Capital to Risk Weighted Assets | 10.50 | % |  | 18.53 | % |  | 17.40 | %
Leverage Ratio of Tier 1 Capital to Average Assets | 6.50 | % |  | 11.06 | % |  | 12.14 | %

Management believes that no conditions or events have occurred since December 31, 2024, that would materially adversely change First Busey’s or Busey Bank’s capital classifications.
NEW ACCOUNTING PRONOUNCEMENTS
Busey reviews new accounting standards as issued. Information relating to accounting pronouncements applicable to Busey appears in “Note 1. Significant Accounting Policies” in the Notes to the Consolidated Financial Statements.
EFFECTS OF INFLATION
The effect of inflation on a financial institution differs significantly from the effect on an industrial company. While a financial institution’s operating expenses, particularly salaries, wages, and employee benefits, are affected by general inflation, the asset and liability structure of a financial institution consists largely of monetary items. Monetary items, such as cash, loans, and deposits, are those assets and liabilities which are or will be converted into a fixed number of dollars regardless of changes in prices. As a result, changes in interest rates have a more significant impact on a financial institution’s performance than does general inflation. For additional information regarding interest rates and changes in net interest income see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operation — Three Years Ended December 31, 2024—Consolidated Average Balance Sheets and Interest Rates” and “Item 7A. Quantitative and Qualitative Disclosures About Market Risk.”
First Busey Corporation (BUSE) | 2024 — 86

Table of Contents
ITEM 7A. 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 Consolidated Balance Sheets to optimize stability in net interest income in consideration of projected future changes in interest rates.
As interest rate changes do not impact all categories of assets and liabilities equally or simultaneously, the asset-liability committee primarily relies on balance sheet and income simulation analysis to determine the potential impact of changes in market interest rates on net interest income. In these standard simulation models, the balance sheet is projected over a one-year and a two-year time horizon and net interest income is calculated under current market rates and assuming permanent instantaneous shifts of +/-100, +/-200, +/-300, and +/-400 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-Two: Basis Point Changes
| December 31, 2024 |  | December 31, 2023 |  | December 31, 2024 |  | December 31, 2023
400 | 8.50 | % |  | 7.38 | % |  | 10.85 | % |  | 8.55 | %
300 | 6.26 | % |  | 5.49 | % |  | 8.01 | % |  | 6.34 | %
200 | 4.05 | % |  | 3.64 | % |  | 5.24 | % |  | 4.20 | %
100 | 1.96 | % |  | 1.81 | % |  | 2.59 | % |  | 2.10 | %
-100 | (1.81) | % |  | (1.91) | % |  | (3.35) | % |  | (2.98) | %
-200 | (3.39) | % |  | (3.86) | % |  | (6.65) | % |  | (6.12) | %
-300 | (4.03) | % |  | (5.60) | % |  | (9.47) | % |  | (9.17) | %
-400 | (4.41) | % |  | (6.91) | % |  | (12.43) | % |  | (11.36) | %

Interest rate risk is monitored and managed within approved policy limits and any temporary exceptions to policy in periods of rapid rate movement are approved and documented. The calculation of potential effects of hypothetical interest rate changes is based on numerous assumptions and should not be relied upon as indicative of actual results. Actual results would likely differ from simulated results due to the timing, magnitude, and frequency of interest rate changes as well as changes in market conditions and management strategies.

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of First Busey Corporation and Subsidiaries
Opinion on the Financial Statements
We have audited the accompanying consolidated balance sheets of First Busey Corporation and its subsidiaries (the Company) as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended December 31, 2024, and the related notes to the consolidated financial statements (collectively, the financial statements). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2024 and 2023, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013, and our report dated February 27, 2025, expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.
Basis for Opinion
These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.
Critical Audit Matters
The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Allowance for Credit Losses on Loans—Adjustments to Historical Loss Factors
As described in Notes 1 and 4 to the financial statements, the Company’s allowance for credit losses totaled $83.4 million, which consists of a reserve on loans collectively evaluated for impairment (a/k/a general reserve) of $81.6 million and a reserve on loans individually evaluated (a/k/a specific reserve) of $1.8 million at December 31, 2024. The allowance for credit losses is measured on a collective loan pool basis when similar risk characteristics exist. On a case‑by‑case basis, a loan may be evaluated on an individual basis based on disparate risk characteristics. The measurement of expected credit losses on collectively evaluated loans is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the amortized cost basis. Adjustments to historical loss information are made for differences in current loan‑specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions such as changes in unemployment rates, property values and other relevant factors. The calculation also contemplates that the Company 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.
We identified the adjustments to historical loss factors component of the allowance for credit losses as a critical audit matter, as auditing the underlying adjustments required significant auditor judgment as amounts determined by management rely on analysis that is highly subjective and includes significant estimation uncertainty.
Our audit procedures related to the adjustments to historical factors within the allowance for credit losses include the following, among others:
•We obtained an understanding of the relevant controls related to the adjustments to historical factors in the calculation of the allowance for credit losses and tested such controls for design and operating effectiveness.
•We tested the completeness and accuracy of data used by management in determining adjustments to historical loss factors including testing the supporting data for agreement to internal or external source data.
•We tested management’s conclusions regarding the appropriateness of the adjustments, including magnitude and directional consistency, to historical loss factors included in the allowance for credit losses calculation.
/s/ RSM US LLP
We or our predecessor firms have served as the Company’s auditor since at least 1980; however, an earlier year could not be established.

FIRST BUSEY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
NOTE 1. SIGNIFICANT ACCOUNTING POLICIES
Organization and Nature of Operations
First Busey Corporation is a financial holding company organized under the laws of Nevada. First Busey Corporation’s subsidiaries provide retail and commercial banking services and payment technology solutions, and offer a full range of financial products and services including depository, lending, security brokerage, investment management, and fiduciary services, to individual, corporate, institutional, and governmental customers through their locations in Illinois, Missouri, southwest Florida and Indianapolis, Indiana. First Busey Corporation and its subsidiaries are subject to the regulations of certain regulatory agencies and undergo periodic examinations by those regulatory agencies.
Busey’s accounting and reporting policies conform to GAAP. The Consolidated Financial Statements include the accounts of First Busey Corporation and its subsidiaries, which include Deed of Trust Services Corporation, and Busey Bank, including Busey Bank’s wholly-owned subsidiaries FirsTech, Pulaski Service Corporation, and Busey Capital Management, Inc. Further, until its dissolution on December 18, 2023, First Busey Risk Management was a subsidiary of First Busey Corporation and included in the Company’s Consolidated Financial Statements. Operating results generated from acquired businesses are included with Busey’s results of operations starting from each date of acquisition. First Busey Corporation and its subsidiaries maintain various limited liability companies that hold specific assets for risk mitigation purposes and are consolidated into Busey’s Consolidated Financial Statements. Intercompany balances and transactions have been eliminated in consolidation.
Because Busey is not the primary beneficiary, the Consolidated Financial Statements exclude the following wholly-owned variable interest entities: First Busey Statutory Trust II, First Busey Statutory Trust III, First Busey Statutory Trust IV, Pulaski Financial Statutory Trust I, Pulaski Financial Statutory Trust II, and Merchants and Manufacturers Bank Statutory Trust I.
Use of Estimates
In preparing the accompanying Consolidated Financial Statements in conformity with GAAP, Busey’s management is required to make estimates and assumptions that affect the amounts reported on the Consolidated Financial Statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near-term relate to the fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.
Trust Assets
Assets held for customers in a fiduciary or agency capacity, other than trust cash on deposit at Busey Bank, are not Busey’s assets and, accordingly, are not included in the accompanying Consolidated Financial Statements. Busey had assets under care of $13.83 billion at December 31, 2024, and $12.14 billion at December 31, 2023.
Cash and Cash Equivalents
Cash and cash equivalents include cash on hand, cash items in process of collection, amounts due from other banks, interest-bearing deposits held with other financial institutions, and federal funds sold. The carrying amount of these instruments is considered a reasonable estimate of fair value.
Busey maintains its cash in deposit accounts, the balance of which, at times, may exceed federally insured limits. Busey has not experienced any losses in such accounts. Management believes Busey is not exposed to any significant credit risk on cash and cash equivalents.

FIRST BUSEY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Business Combinations
Business combinations are accounted for under ASC Topic 805 “Business Combinations” using the acquisition method of accounting. The acquisition method of accounting requires that the assets acquired and the liabilities assumed are recognized, measured at their estimated fair values, as of the date Busey obtains control of the acquiree (the acquisition date). To estimate fair values of assets acquired and liabilities assumed, Busey may utilize third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Further, management assumptions require consideration of future growth rates, future attrition, discount rates, multiples of earnings or other relevant factors.
Operating results generated from acquired businesses are included with Busey’s results of operations starting from each acquisition date. Acquisition related costs are costs that Busey incurs to effect a business combination, and may include legal, accounting, valuation, other professional or consulting fees, system conversions, and marketing costs. Busey accounts for acquisition related costs by recording them as expenses in the periods in which the costs are incurred and the services are received. Costs that Busey expects, but is not obligated to incur in the future, to effect its plan to exit an activity of an acquiree or to terminate the employment of an acquiree’s employees are not liabilities at the acquisition date. Instead, Busey recognizes these costs in its post-combination Consolidated Financial Statements in accordance with other applicable accounting guidance.
Securities
Debt Securities Available for Sale
Debt securities classified as available for sale are those debt securities that Busey intends to hold for an indefinite period of time, but not necessarily to maturity. Any decision to sell a security classified as available for sale would be based on factors including significant movements in interest rates, changes in the maturity mix of Busey's assets and liabilities, liquidity needs, regulatory capital considerations, and other similar factors. Debt securities available for sale are carried at fair value, with unrealized gains and losses reported in OCI, net of taxes.
Purchase premiums and discounts are recognized in interest income using the interest method over the terms of the securities. The amortization period for certain callable debt securities held at a premium are amortized to the earliest call date, while discounts on debt securities are amortized to maturity. Gains and losses on the sale of debt securities available for sale are recorded on the trade date and are determined using the specific identification method.
Debt securities available for sale are not within the scope of the current expected credit losses methodology, however, the accounting for credit losses on these securities is affected by ASC Subtopic 326-30 “Financial Instruments-Credit Losses—Available-for-Sale Debt Securities.” A debt security available for sale is impaired if the fair value of the security declines below its amortized cost basis. To determine the appropriate accounting, Busey must first determine if it intends to sell the security or if it is more likely than not that it will be required to sell the security before the fair value increases to at least the amortized cost basis. If either of those selling events is expected, Busey will write down the amortized cost basis of the security to its fair value. This is achieved by writing off any previously recorded allowance, if applicable, and recognizing any incremental impairment through earnings. If Busey neither intends to sell the security nor believes it is more likely than not that the Company will be required to sell the security before the fair value recovers to the amortized cost basis, Busey must determine whether any of the decline in fair value has resulted from a credit loss, or if it is entirely the result of noncredit factors.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Busey considers the following factors in assessing whether the decline is due to a credit loss:
•Extent to which the fair value is less than the amortized cost basis;
•Adverse conditions specifically related to the security, an industry, or a geographic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset-backed debt security, in the financial condition of the underlying loan obligors);
•Payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future;
•Failure of the issuer of the security to make scheduled interest or principal payments; and
•Any changes to the rating of the security by a rating agency.
Impairment related to a credit loss must be measured using the discounted cash flow method. Credit loss recognition is limited to the fair value of the security. Impairment is recognized by establishing an allowance for the debt security through the provision for credit losses. Impairment related to noncredit factors is recognized in AOCI, net of applicable taxes. Busey did not recognize any credit impairment on debt securities available for sale in 2024, 2023, or 2022.
Debt Securities Held to Maturity
Debt securities classified as held to maturity are those debt securities that Busey has the intent and ability to hold to maturity and are carried at amortized cost. In 2022, Busey elected to transfer a portion of the agency mortgage-backed securities portfolio from available for sale to held to maturity. While held to maturity securities are within the scope of CECL, the standard allows for an assumption of zero credit losses when the expectation of non-payment is zero. The risk of credit loss related to mortgage-backed securities issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises is considered zero, therefore requiring no allowance to be recorded.
Accrued interest receivable for both debt securities available for sale and debt securities held to maturity totaled $10.5 million at December 31, 2024, and is excluded from the estimate of credit losses. Accrued interest receivable is reported in other assets on the Consolidated Balance Sheets.
Equity Securities
Equity securities are carried at fair value with changes in fair value recognized in earnings.
Loans Held for Sale
Loans held for sale include mortgage loans which Busey intends to sell to investors and/or the secondary mortgage market.
Busey accounts for loans held for sale at LOCOM. Loans held for sale are carried at amortized historical cost less loan write-offs and downward fair value adjustments, as may be applicable. Net unrealized losses, if any, are recognized through a valuation allowance by charges to income. Gains and losses on sales of loans are recognized at settlement dates and are determined by the difference between the sales proceeds and the carrying amount, net of the value of any servicing assets for loans that were sold with servicing rights retained.

Loan Servicing
Servicing assets are recognized when servicing rights are acquired or retained through the sale of mortgage and government-guaranteed commercial loans. The unpaid principal balances of loans serviced by Busey for the benefit of others totaled $582.5 million as of December 31, 2024, and $1.49 billion as of December 31, 2023, and are not included in the accompanying Consolidated Balance Sheets. During the first quarter of 2024, Busey sold the mortgage servicing rights on approximately $923.5 million of one- to four-family mortgage loans for an estimated pre-tax gain of $7.5 million, which enabled Busey to sell available-for-sale debt securities with a book value of approximately $108.2 million for a pre-tax loss of $6.8 million.
Servicing rights are initially recorded at estimated fair value, which is determined using a valuation model that calculates the present value of estimated future net servicing income. Capitalized servicing rights are reported in other assets and are amortized into noninterest income in proportion to, and over the period of, the estimated future net servicing income of the underlying financial assets. The amortization of mortgage servicing rights is included in mortgage revenue. The amortization of government-guaranteed commercial loan servicing rights is included in other income.
Servicing rights are periodically evaluated for impairment based on the fair value of those rights as compared to the carrying amount. Fair values are estimated using discounted cash flows based on expected prepayment rates and other inputs. For purposes of measuring impairment, servicing rights are stratified by one or more predominant characteristics of the underlying loans. A valuation allowance is recognized in the amount by which the amortized cost of the rights for each stratum exceeds its fair value, if any. If Busey later determines that all or a portion of the impairment no longer exists for a particular group of loans, a reversal of the allowance may be recorded in current period earnings. Busey had an immaterial amount of impairment recorded at December 31, 2024 and 2023.
Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal and are recorded as income when earned.
Portfolio Loans
Loans that management has the intent and ability to hold for the foreseeable future, or until maturity or pay-off, are reported at the principal balance outstanding, net of purchase premiums and discounts, deferred origination fees and costs, charge-offs, and the ACL.
Loan origination fees, net of certain direct loan origination costs, are deferred and the net amount is amortized as an adjustment of the related loan’s yield. Busey amortizes the net amount over the contractual life of the related loan.
Interest income is accrued daily on outstanding loan balances. 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 provisions. Loans may be placed on non-accrual status regardless of whether or not such loans are considered past due. Past due status is based on the contractual terms of the loan.
Interest accrued but not collected for loans that are charged-off or placed on non-accrual status is reversed against interest income. The interest on non-accrual loans is accounted for on the cost-recovery method, until returned to accrual status. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Loan Modifications
Busey’s loan portfolio includes certain loans that have been modified in accordance with loan refinancing and restructuring guidance in ASC Subtopic 310-20-35-9 through 35-11 “Receivables—Nonrefundable Fees and Other Costs—Subsequent Measurement—Loan Refinancing or Restructuring” for borrowers experiencing financial difficulty. For additional information about loan modifications for borrowers experiencing financial difficulty, see “Note 4. Portfolio Loans.”
Allowance for Credit Losses
The ACL is a significant estimate on Busey’s Consolidated Financial Statements, affecting both earnings and capital. 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. Portfolio loans are charged off against the ACL when management believes the loan balance is uncollectible. Recoveries will be recognized up to the aggregate amount of previously charged-off balances. The ACL is established through the provision for credit loss charged to income.
A loan’s amortized cost basis is comprised of the unpaid principal balance of the loan net of charge-offs, accrued interest receivable, purchase premiums or discounts, and net deferred origination fees or costs. Busey has estimated its allowance on the amortized cost basis, exclusive of government guaranteed loans and accrued interest receivable. Further, as permitted under the practical expedient provided within ASC 326-20-35-6, Busey did not record an ACL for its Life Equity Loan® portfolio due to no expected credit loss at default. Busey writes-off uncollectible accrued interest receivable in a timely manner and has elected to not measure an allowance for accrued interest receivable. Busey presents the aggregate amount of accrued interest receivable for all financial instruments in other assets on the Consolidated Balance Sheets and the balance of accrued interest receivable is disclosed in “Note 20. Fair Value Measurements.”
Busey’s methodology influences, and is influenced by, Busey’s overall credit risk management processes. The ACL is managed 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. 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.
The 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 amortized cost basis. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions such as changes in unemployment rates, property values, and other relevant factors. 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. 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.
Ongoing impacts of CECL will be dependent upon changes in economic conditions and forecasts, originated and acquired loan portfolio composition, prepayment speeds, credit performance trends, portfolio duration, and other factors.

Assets Purchased with Credit Deterioration
Acquired loans are separated into two categories based on the credit risk characteristics of the underlying borrowers: (1) PCD, for loans which have experienced more than insignificant credit deterioration since origination, or (2) all other loans.
For PCD loans, an ACL is determined at the date of acquisition using the same methodology as other loans held for investment. This initial ACL, when determined on a collective basis, is allocated to the individual loans, and the sum of each loan’s purchase price and ACL becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. The ACL on PCD loans is recorded in the acquisition accounting and no provision for credit losses is recognized at the acquisition date. Subsequent changes to the ACL are recorded as a charge to the provision for credit losses.
For all other loans, an ACL is established immediately after the acquisition through a charge to the provision for credit losses.
Upon adoption of ASC Topic 326 “Financial Instruments-Credit Losses” Busey applied the prospective transition approach for financial assets considered PCD that were previously classified as PCI and accounted for under ASC Subtopic 310-30 “Receivables—Loans and Debt Securities Acquired with Deteriorated Credit Quality.” In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. The amortized cost basis of these PCD assets was adjusted to reflect an ACL for any remaining credit discount. The noncredit discount is being accreted into interest income using the January 1, 2020, effective interest rate. Subsequent changes in expected cash flows will be adjusted through the ACL.
Other Real Estate Owned and Other Repossessed Assets
OREO and other repossessed assets represent properties and other assets acquired through foreclosure or other proceedings in settlement of loans. OREO and other repossessed assets are recorded at the fair value of the property or asset, less estimated costs of disposal, which establishes a new cost basis. Any adjustment to fair value at the time of transfer to OREO or other repossessed assets is charged to the ACL. OREO property and other repossessed assets are evaluated regularly to ensure the recorded amount is supported by its current fair value; write downs or valuation allowances to reduce the carrying amount to fair value less estimated costs to dispose are recorded, as necessary. OREO and other repossessed assets are included in other assets on the Consolidated Balance Sheets. Revenue, expense, gains, and losses from the operations of foreclosed assets are included in earnings.
Long-Lived Assets
Long-lived assets, including premises and equipment, right of use assets, and intangible assets, are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of the asset may not be recoverable. An impairment loss is recognized when estimated undiscounted future cash flows from operations of the asset are less than the carrying value of the asset. Cash flows used for this analysis are those directly associated with, and that are expected to arise as a direct result of, the use and eventual disposition of the asset. Any impairment loss is measured as the amount by which the carrying value of the asset exceeds its fair value.

Premises and Equipment
Land is carried at cost less accumulated depreciation of depreciable land improvements. Premises and equipment are stated at cost less accumulated depreciation. Depreciation is computed by the straight-line method over the estimated useful lives of the assets. The estimated useful lives for premises and equipment are:

Asset Description |  | Estimated Useful Life
Buildings and improvements |  | 3 — 40 years
Furniture and equipment |  | 3 — 10 years

Premises and equipment are reviewed for impairment in accordance with Busey’s policies regarding long-lived assets.
Bank property held for sale, included in premises and equipment, represents certain banking center office buildings which Busey had 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, and depreciation has been stopped.
Leases
A determination is made at inception if an arrangement contains a lease. For arrangements containing leases, Busey recognizes leases on the Consolidated Balance Sheets as right of use assets and corresponding lease liabilities. Lease-related assets, or 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-related 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, that renewal term is included in the calculation of the right of use asset and lease liability.
Operating lease expense is recognized on a straight-line basis over the lease term, including any renewal terms available through options to renew that Busey is reasonably certain to exercise. Variable lease payments are expensed as incurred.
Right of use assets are reviewed for impairment in accordance with Busey’s policies regarding long-lived assets.

Goodwill and Other Intangibles
Goodwill represents the excess of consideration transferred in a business combination over the fair value of the net assets acquired. Goodwill is not amortized but is subject to at least annual impairment assessments. A separate goodwill impairment assessment is performed for each reporting unit on the goodwill that has been allocated to it. A reporting unit is a component of an operating segment that constitutes a business for which discrete financial information is available, and segment management regularly reviews the operating results of that component. Busey’s reporting units are the same as its operating segments. Busey has established December 31 as the annual impairment assessment date for each of its reporting units. As part of this assessment, each reporting unit's carrying value is compared to its fair value.
Busey estimates the fair value of its reporting units as of the measurement date utilizing valuation methodologies including comparable company analysis and precedent transaction analysis. Goodwill is considered impaired if the carrying value of the reporting unit exceeds its fair value. There was no impairment as of December 31, 2024 or 2023.
Other intangible assets consist of core deposit and acquired customer relationship intangible assets arising from acquisitions. Other intangible assets are amortized over their estimated useful lives, and are reviewed for impairment in accordance with Busey’s policies regarding long-lived assets.
See “Note 8. Goodwill and Other Intangible Assets” for additional information.
Cash Surrender Value of Bank Owned Life Insurance
Busey has purchased, or acquired through acquisitions, life insurance policies on certain executives and senior officers. Life insurance is recorded at its cash surrender value, which approximates its fair value.
Busey maintains a liability for post-employment benefits related to split-dollar life insurance arrangements. In an endorsement split-dollar life insurance arrangement, the employer owns and controls the policy, and the employer and employee split the life insurance policy’s cash surrender value and/or death benefits. If the employer agrees to maintain a life insurance policy during the employee’s retirement, the present value of the cost of maintaining the insurance policy is accrued over the employee’s active service period. Similarly, if the employer agrees to provide the employee with a death benefit, the present value of the death benefit is accrued over the employee’s active service period. Busey accrued liabilities for these arrangements totaling $5.7 million as of December 31, 2024, and $5.6 million as of December 31, 2023. Liabilities for post-employment benefits are included in other liabilities on the Consolidated Balance Sheets.
Restricted Bank Stock
During the fourth quarter of 2024 Busey Bank became a member of the Federal Reserve System. Federal Reserve member banks are required to own a certain amount of Federal Reserve Bank stock. Busey's investment in Federal Reserve Bank stock was $43.9 million as of December 31, 2024. Busey’s investment in Federal Reserve Bank stock represents approximately half of the total required subscription, and the remaining half is unpaid and remains subject to call by the Federal Reserve Bank. As such, Busey reserved cash of $43.9 million as of December 31, 2024.
Busey Bank is a member of the FHLB system. FHLB members are required to own a certain amount of FHLB stock based on the level of borrowings and other factors, and may invest in additional amounts. Busey's investment in FHLB stock was $6.0 million as of both December 31, 2024 and 2023.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Federal Reserve Bank stock and FHLB stock are carried at cost in restricted bank stock on the Consolidated Balance Sheets. Cash reserves are included in interest-bearing deposits as part of Busey’s total cash and cash equivalents balances reported on the Consolidated Balance Sheets. Dividends are reported as interest income on the Consolidated Statements of Income. Dividend income is accrued on Federal Reserve Bank stock and is recognized when declared on FHLB stock.
Transfers of Financial Assets
Transfers of financial assets are accounted for as sales only when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when: (1) the assets have been isolated from Busey’s assets, (2) the transferee obtains the right to pledge or exchange the assets it receives, and no condition both constrains the transferee from taking advantage of its right to pledge or exchange and provides more than a trivial benefit to the transferor, and (3) Busey does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity or the ability to unilaterally cause the holder to return specific assets. When transfers of financial assets fail to meet these criteria, those transfers are accounted for as secured borrowings.
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. Busey is no longer subject to U.S. federal, state, or local income tax examinations by tax authorities for the years before 2021.
Under GAAP, a valuation allowance is required to be recognized if it is more likely than not that the deferred tax assets will not be realized. The determination of the recoverability of the deferred tax assets is highly subjective and dependent upon judgment concerning management’s evaluation of both positive and negative evidence, the forecasts of future income, applicable tax planning strategies, and assessments of current and future economic and business conditions.
In 2024, Busey recorded a one-time deferred tax valuation adjustment of $1.4 million resulting from a change to the Illinois apportionment rate due to recently enacted regulations. These new regulations are expected to lower Busey’s ongoing tax obligation in future periods, but created a negative adjustment to the carrying value of Busey’s deferred tax asset in 2024. Management believes that it is more likely than not that the deferred tax assets included in the accompanying Consolidated Financial Statements will be fully realized. Busey determined that no valuation allowance was required as of December 31, 2024, or 2023.
Positions taken in tax returns may be subject to challenge upon examination by the taxing authorities. Uncertain tax positions are initially recognized on the Consolidated Financial Statements when it is more likely than not the position will not be sustained upon examination by the tax authorities. Such tax positions are both initially and subsequently measured as the largest amount of tax benefit that has a greater than 50% likelihood of being realized upon settlement with the tax authority, assuming full knowledge of the position and all relevant facts. When applicable, Busey recognizes interest accrued related to unrecognized tax benefits and penalties in operating expenses.
At December 31, 2024, 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. Other than this, Busey had no accruals for payments of interest and penalties related to uncertain tax positions at December 31, 2024, or 2023. Further, in February of 2025, Busey received notice of audit initiation from the Illinois Department of Revenue for M&M’s tax filings for the tax years 2022 and 2023.

Tax Credit and Other Investments in Unconsolidated Entities
Busey has invested in certain tax-advantaged projects promoting affordable housing, new markets, and historic rehabilitation. These investments are designed to generate returns primarily though the realization of federal and state income tax credits and other tax benefits, such as tax deductions from operating losses of the investments, over specified time periods. These investments are considered to be variable interest entities, and are accounted for under the equity, cost, or proportional amortization practical expedient methods, as appropriate. These investments involve significant management judgments, including a determination of which entities have the power to direct activities, and whether these entities are variable interest entities. Busey is required to evaluate whether to consolidate a variable interest entity at both inception and on an ongoing basis. Busey is not required to consolidate variable interest entities in which it has concluded it does not have a controlling financial interest and is not the primary beneficiary. Busey’s maximum exposure to loss related to its investments in these unconsolidated variable interest entities is limited to the carrying amount of the investment, net of any unfunded capital commitments and previously recorded tax credits which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level. Busey believes potential losses from these investments are remote. In addition, Busey has private equity investments, which are primarily in funds that invest in small businesses across diverse sectors including, but not limited to, financial technology, business services, manufacturing, agribusiness, healthcare, software as a service, and environmental, or supporting the preservation of affordable housing.
Upon adoption of ASU 2023-02 on January 1, 2024, Busey elected to apply the proportional amortization method in accounting for investments in tax-advantaged projects. Income tax credits and other tax benefits, net of investment amortization, were included as a component of Busey’s estimated annual effective tax rate used for the calculation of income taxes presented on the Consolidated Statements of Income.
For additional information regarding these investments, see “Note 14. Tax Credit and Other Investments in Unconsolidated Entities.”
Treasury Stock
Treasury stock acquired is recorded at cost. Treasury stock issued is valued based on the “first-in, first-out” method. Gains and losses on issuance are recorded as increases or decreases to additional paid-in capital.
Stock-Based Employee Compensation
Busey’s equity incentive plans are designed to encourage ownership of its common stock by its employees and directors, to provide additional incentive for them to promote the success of Busey’s business, and to attract and retain talented personnel.
2020 Equity Plan
The 2020 Equity Plan was originally approved by stockholders at the 2020 Annual Meeting of Stockholders. A description of the 2020 Equity Plan, as originally approved, can be found in Appendix A within Busey’s Proxy Statement for the 2020 Annual Meeting of Stockholders filed on April 9, 2020. Upon the 2020 Equity Plan’s original approval, it replaced the 2010 Equity Incentive Plan and the First Community 2016 Equity Incentive Plan, which, from time to time, Busey used to grant equity awards to legacy employees of First Community. Under the terms of the 2020 Equity Plan, Busey has granted RSU, DSU, and PSU awards.

An amendment to and restatement of the 2020 Equity Plan was approved by stockholders at the 2023 Annual Meeting of Stockholders. The terms of the amended and restated 2020 Equity Plan are substantially identical to those of the originally approved 2020 Equity Plan, other than a 1,350,000 increase in the number of shares authorized for issuance under the plan. More information can be found in Appendix A within Busey’s Proxy Statement for the 2023 Annual Meeting of Stockholders filed on April 14, 2023.
All of Busey’s employees and directors and those of its subsidiaries are eligible to receive awards under the plans.
RSU Awards
Busey grants RSU awards to members of management periodically throughout the year. RSU awards are stock-based awards for which vesting is conditional upon meeting established service criteria. Each RSU is equivalent to one share of Busey’s common stock. Busey’s RSUs have requisite service periods ranging from one year to five years, and are subject to accelerated vesting upon eligible retirement from Busey. Recipients earn quarterly dividend equivalents on their respective RSUs, which entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances.
PSU Awards
Busey grants PSU awards to members of management periodically throughout the year. PSU awards are stock-based awards for which vesting is conditional upon meeting established performance criteria for the applicable performance period and remaining employed through the end of such performance period. Each PSU is equivalent to one share of Busey’s common stock. The number of PSUs that ultimately vest will be determined based on the extent to which 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 each dividend date during the performance period.
DSU Awards
Busey grants DSU awards to its non-employee directors. DSU awards are stock-based awards with a deferred settlement date. Each DSU is equivalent to one share of Busey’s common stock. DSUs vest over a one-year period following the grant date. Under the 2020 Equity Plan, DSUs are generally subject to the same terms as RSUs, except that following vesting of DSUs, settlement occurs within 30 days following the earlier of separation from the board or a change in control of the Company. After vesting and prior to delivery, DSUs will continue to earn dividend equivalents.
Stock Options
Busey has outstanding stock options assumed from acquisitions. All stock options that remained outstanding as of December 31, 2024, were fully vested.
Employee Stock Purchase Plan
The First Busey Corporation ESPP was approved at Busey’s 2021 Annual Meeting of Stockholders and details can be found in Appendix A within First Busey’s Definitive Proxy Statement filed with the SEC on April 8, 2021. The purpose of the ESPP is to provide a means through which Busey associates may acquire a proprietary interest in the Company by purchasing shares of its common stock at a discounted price through voluntary payroll deductions, to assist in retaining the services of current associates and securing and retaining the services of new associates, and to provide incentives for Busey associates to exert maximum efforts toward the Company’s success.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Because the ESPP provides opportunity for Busey associates to purchase Busey’s common stock at a 15% discount from the market price, the plan is considered to be a compensatory plan under current accounting guidance. Therefore, the entire amount of the discount is recognized in salaries, wages, and employee benefits on the Consolidated Statements of Income.
See “Note 16. Stock-based Compensation” for further discussion.
Off-Balance Sheet Arrangements
In the normal course of business, to meet the financing needs of its customers, Busey is a party to credit-related financial instruments with off-balance-sheet risk, including commitments to extend credit and standby letters of credit. These instruments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized on the Consolidated Balance Sheets. Busey’s exposure to credit loss is represented by the contractual amount of the commitments. Busey uses the same credit policies in making commitments and conditional obligations as it does for on-balance-sheet instruments.
Commitments to extend credit are agreements to lend to a customer as long as no condition established in the contract has been violated. These commitments are generally at variable interest rates, they generally have fixed expiration dates or other termination clauses, and they may require the customer to pay a fee. Commitments for equity lines of credit may expire without being drawn upon; therefore, the total commitment amounts do not necessarily represent future cash requirements. These commitments may be secured based on management’s credit evaluation of the borrower.
Standby letters of credit are conditional commitments Busey has issued to guarantee the performance of a customer’s obligation to a third-party. Those guarantees are primarily issued to support public and private borrowing arrangements, including bond financing and similar transactions. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. Busey holds collateral, which may include accounts receivable, inventory, property and equipment, and income producing properties, supporting those commitments if deemed necessary. In the event the customer does not perform in accordance with the terms of the agreement with the third-party, Busey would be required to fund the commitment. If the commitment is funded, Busey would be entitled to seek recovery from the customer.
Busey estimates expected credit losses for off-balance sheet arrangements over the contractual period during which it is exposed to credit risk via a present contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the issuer. To be considered unconditionally cancellable for accounting purposes, Busey must have the ability to, at any time, with or without cause, refuse to extend credit under the commitment. Off-balance-sheet credit exposure segments share the same risk characteristics as portfolio loans. Busey incorporates a probability of funding and utilizes the ACL loss rates to calculate a reserve for off-balance-sheet credit exposure, which is carried on the Consolidated Balance Sheets in other liabilities rather than as a component of the ACL. The reserve for off-balance-sheet credit exposure is adjusted as a provision for off-balance-sheet credit exposure and is reported as a component of noninterest expense in the accompanying Consolidated Statements of Income. Liabilities recorded as reserves for Busey’s off-balance sheet credit exposure under these commitments totaled $6.0 million as of December 31, 2024, and $7.1 million as of December 31, 2023.
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 with customers and other third parties.

Interest Rate Swaps Designated as Cash Flow Hedges
Busey entered into derivative instruments designated as cash flow hedges. For a derivative instrument that qualifies and is designated as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in fair value of components excluded from the assessment of effectiveness are recognized in current earnings.
Interest Rate Swaps Not Designated as Hedges
Busey may offer derivative contracts to its customers in connection with their risk management needs. Busey manages the risk associated with these contracts by entering into equal and offsetting derivatives with third-party dealers. Generally, these derivatives have 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.
Interest Rate Lock Commitments
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 Consolidated Financial Statements, with changes in the fair values of the corresponding derivative financial assets or liabilities recorded as either a charge or credit to mortgage revenue during the period in which the changes occurred.
Forward Sales Commitments
Busey economically hedges mortgage loans held for sale and interest rate lock commitments issued to its residential loan customers related to loans that will be held for sale by obtaining corresponding forward sales commitments with an investor to sell the loans at an agreed-upon price at the time the interest rate locks are issued to the customers. Forward sales commitments that meet the definition of derivative financial instruments under ASC Topic 815 “Derivatives and Hedging” are carried at their fair values in other assets or other liabilities on the Consolidated Financial Statements. While such forward sales commitments generally served as an economic hedge to mortgage loans held for sale and interest rate lock commitments, Busey did not designate them for hedge accounting treatment. Changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to mortgage revenue during the period in which the changes occurred.
Risk Participation Agreements
Busey has entered into risk participation agreements to manage the credit risk of its derivative position. These agreements transfer credit risk related to an interest rate swap to another financial institution. Risk participation agreements that Busey has entered into are structured as follows:

•Busey has a swap agreement with a customer. Busey (purchaser) entered into a risk participation agreement with a counterparty (seller), under which the counterparty receives a fee to accept a portion of the credit risk. If Busey’s customer defaults on the swap contract, the counterparty to the risk participation agreement must reimburse Busey for the counterparty's percentage of the positive fair value (from the purchaser’s perspective) of the customer swap as of the default date. If the customer swap has a negative fair value (from the purchaser’s perspective), the counterparty has no reimbursement requirements. If Busey’s customer defaults on the swap contract and the counterparty (seller) fulfills its payment obligations under the risk participation agreement, the counterparty (seller) is entitled to a pro rata share of Busey’s claim against the customer under the terms of the swap agreement.

Fair Value of Financial Instruments
Fair values of financial instruments are estimated using relevant market information and other assumptions, as more fully disclosed in “Note 20. Fair Value Measurements.” Fair value estimates involve uncertainties and matters of significant judgment regarding interest rates, credit risk, prepayments, and other factors, especially in the absence of broad markets for particular items. Changes in assumptions or in market conditions could significantly affect these estimates.
Comprehensive Income (Loss)
Accounting principles generally require that recognized revenue, expenses, gains, and losses be included in net income. Although certain changes in assets and liabilities, such as unrealized gains and losses on available for sale debt securities and unrealized gains and losses on cash flow hedges, are reported net of taxes as a separate component within the equity section of the balance sheet, such items, along with net income, are components of comprehensive income (loss).

Segment Disclosure
Operating segments are components of a business that (1) engage in business activities from which the component may earn revenues and incur expenses; (2) have operating results that are reviewed regularly by the entity’s chief operating decision maker to make decisions about resources to be allocated to the segments and assess their performance; and (3) for which discrete financial information is available. Busey’s chief executive officer is its chief operating decision maker. Busey’s has three reportable segments: Banking, Wealth Management, and FirsTech. See “Note 23. Operating Segments and Related Information” for further discussion.
Revenue
ASC Topic 606 “Revenue from Contracts with Customers” outlines a single model for companies to use in accounting for revenue arising from contracts with customers and supersedes most prior revenue recognition guidance, including industry-specific guidance. ASC Topic 606 requires that companies recognize revenue based on the value of transferred goods or services as they occur in the contract and establishes additional disclosures. Busey’s revenue is comprised of net interest income, which is explicitly excluded from the scope of ASC Topic 606, and noninterest income. Busey has evaluated its noninterest income and the nature of its contracts with customers and determined that further disaggregation of revenue beyond what is presented in the accompanying Consolidated Financial Statements is not necessary. Busey satisfies its performance obligations on its contracts with customers as services are rendered, so there is limited judgment involved in applying ASC Topic 606 that affects the determination of the timing and amount of revenue from contracts with customers.
Descriptions of Busey’s primary revenue generating activities that are within the scope of ASC Topic 606, and are presented in the accompanying Consolidated Statements of Income as components of noninterest income, include wealth management fees, payment technology solutions, and fees for customer services.
Wealth Management Fees
Wealth management fees represent fees due from wealth management customers as consideration for managing the customers' assets. Wealth management and trust services include custody of assets, investment management, fees for trust services, and other fiduciary activities. Also included are fees received from a third-party broker-dealer as part of a revenue sharing agreement for fees earned from customers that Busey refers to the third party. Revenue is recognized when the performance obligation is completed, which is generally monthly.
Payment Technology Solutions
Payment technology solutions revenue represents transaction-based fees for technology-driven payment solutions primarily for walk-in, lockbox, interactive voice recognition, and online bill payments through Busey Bank’s subsidiary, FirsTech. Revenue is recognized when the performance obligation is completed, which is generally monthly.
Fees for Customer Services
Fees for customer services consist of time-based revenue from service fees for account maintenance, item-based revenue from fee-based activity, and transaction-based fee revenue. Revenue is recognized when the performance obligation is completed, which is generally monthly for account maintenance services, or when a transaction has been completed. Payments for such performance obligations are generally received at the time the performance obligations are satisfied.

Reclassifications
Reclassifications have been made to certain prior year account balances, with no effect on net income or stockholders’ equity, to be consistent with the classifications adopted as of and for the year ended December 31, 2024.
Impact of Recently Adopted Accounting Standards
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. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations, but resulted in enhanced disclosures.
In March 2023, the FASB issued ASU 2023‑02 “Investments—Equity Method and Joint Ventures (Topic 323),” permitting an election to use the proportional amortization method to account for equity investments made primarily for the purpose of receiving income tax credits and other income tax benefits, regardless of the tax credit program from which the income tax credits are received, provided that certain conditions are met. The proportional amortization method results in the cost of the investment being amortized in proportion to the income tax credits and other income tax benefits received, with the amortization of the investment and the income tax credits being presented net in the income statement as a component of income tax expense. Busey adopted this standard on a modified retrospective basis on January 1, 2024. Upon adoption, Busey recorded an after-tax decrease to retained earnings of $1.4 million for the cumulative effect of adopting ASU 2023‑02. This transition adjustment included a $2.4 million decrease in other assets, a $0.5 million decrease in other liabilities, and a $0.5 million increase in deferred tax assets.
In March 2023, the FASB issued ASU 2023‑01 “Leases (Topic 842): Common Control Arrangements,” which requires amortization over the useful life of leasehold improvements (not the lease term) when the lease is between entities under common control, and any value of such leasehold improvements remaining at the end of the lease term is to be accounted for as a transfer between entities under common control. Busey adopted this standard on a prospective basis on January 1, 2024. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.
In June 2022, the FASB issued ASU 2022-03 “Fair Value Measurements (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions,” which clarifies that contractual restrictions on the sale of equity securities are not considered in measuring the fair value of those equity securities, and further that contractual sale restrictions cannot be recognized and measured as a separate unit of account. Busey adopted this standard on a prospective basis on January 1, 2024. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.
Recently Issued Accounting Standards Not Yet Adopted
In 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
In March 2024, the FASB issued ASU 2024-01 “Compensation-Stock Compensation (Topic 718): Scope Application of Profits Interest and Similar Awards” to clarify that certain “profits interests” are within the scope of Topic 718 by amending the language and providing illustrative examples on how the scope guidance in paragraph 718-10-15-3 should be applied. This update is intended to improve clarity of the accounting standards codification, not to change the guidance. This update may be applied on a retrospective or prospective basis and will be effective for Busey for annual and interim reporting periods beginning January 1, 2025. Early adoption is permitted. Busey does not currently have any Profit Interest and Similar Awards, so does not expect adoption of this ASU to have any impact on its financial position and results of operations.
In December 2023, the FASB issued ASU 2023‑09 “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires more detailed disclosures of income taxes paid net of refunds received, income from continuing operations before income tax expense or benefit, and income tax expense from continuing operations. This standard is to be applied on a prospective basis, with retrospective application permitted, and will be effective for Busey for annual reporting periods beginning with the fiscal year ending December 31, 2025. Busey does not expect adoption of this 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 Consolidated Financial Statements included in this Annual Report on Form 10‑K were issued. Busey issued a Form 8‑K on February 21, 2025, regarding the departure of a named executive officer, and during the first quarter of 2025 expects to record related severance expenses according to Schedule 1 of the Separation Letter that was filed as Exhibit 10.1 to the Form 8‑K. Other than this, there were no significant subsequent events for the year ended December 31, 2024, through the filing date of these Consolidated Financial Statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Under the terms of the merger agreement, CrossFirst stockholders will have the right to receive for each share of CrossFirst common stock 0.6675 of a share of Busey’s common stock with a cash payment in lieu of any fractional shares, and for each share of CrossFirst Series A Perpetual Preferred Stock one share of a newly created series of Busey preferred stock or, at the election of Busey, an amount of cash equal to the liquidation preference thereof, plus any unpaid dividends thereon through the effective time of the merger.
On December 20, 2024, Busey and CrossFirst stockholders voted to approve the merger. On January 16, 2025, Busey received regulatory approval from the Board of Governors of the Federal Reserve System for the merger. The transaction has also been approved by the Illinois Department of Financial and Professional Regulation and the Kansas Office of the State Bank Commissioner. Busey and CrossFirst intend to close the merger on March 1, 2025, subject to the satisfaction of the remaining customary closing conditions. It is anticipated that CrossFirst Bank will merge with and into Busey Bank in mid-2025. At the time of the bank merger, CrossFirst Bank locations will become banking centers of Busey Bank.
In connection with the CrossFirst merger, Busey incurred one-time pretax acquisition-related expenses of $3.9 million in 2024, which are reported as components of noninterest expense on the accompanying Consolidated Statements of Income. Of this amount, $3.1 million represents legal, professional, and consulting fees incurred to consummate the acquisition, with the remainder of the expenses comprised primarily of marketing, consulting, and travel expenses.
For further details on the merger, see the 8-K announcing the merger filed with the SEC on August 27, 2024.
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® products to Busey’s existing suite of services and expanded Busey’s presence in the suburban Chicago market. M&M’s results of operations were included in Busey’s results of operation beginning April 1, 2024.
Merger of M&M Bank into Busey Bank
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.
Merger Consideration
At the effective time of the Merger, each share of M&M common stock converted to the right to receive, at the election of each stockholder and subject to proration and adjustment as provided in the Merger Agreement, either (1) $117.74 in cash (“Cash Election”), (2) 5.7294 shares of Busey common stock (“Share Election”), or (3) mixed consideration of $34.55 in cash and 4.0481 shares of Busey common stock (“Mixed Election”).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Most of the M&M common stockholders who submitted an election form by the election deadline made the Share Election to receive their Merger consideration solely in the form of shares of Busey common stock. As a result of the elections of M&M common stockholders, and in accordance with the proration and adjustment provisions of the Merger Agreement, the Merger consideration paid to M&M common stockholders was comprised of an aggregate of 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 Merger Agreement, M&M common stockholders that did not make an election or submit a properly completed election form by the election deadline of March 29, 2024, received cash consideration of $117.74 for each share of M&M common stock held. No fractional shares of Busey common stock were issued in the Merger. Fractional shares were paid in cash at the rate of $23.32 per share.
Additional Merger consideration of $3.0 million was paid to redeem 300 shares of M&M preferred stock.
Acquisition Accounting
This transaction 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. Fair values, including initial accounting for deferred taxes, are subject to refinement for up to one year after the closing date as additional information regarding the closing date fair values becomes available. Fair value adjustments totaling $0.4 million were recorded during the year ended December 31, 2024, as additional information became available regarding unrecorded assets and liabilities. Busey does not expect any further adjustments will be necessary.
As the total consideration paid for M&M exceeded the estimated fair value of net assets acquired, goodwill of $15.8 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, and was assigned to the Banking operating segment. None of the goodwill recognized in the M&M acquisition is expected to be tax deductible.

Unrealized and unrecognized losses were related to changes in market interest rates and market conditions that do not represent credit-related impairments. Unless part of a corporate strategy or restructuring plan, Busey does not intend to sell securities that are in an unrealized or unrecognized loss position, and it is more likely than not that 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 was recorded in relation to debt securities, and the impairment related to noncredit factors on debt securities available for sale is recognized in AOCI, net of applicable taxes. As of December 31, 2024, Busey did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 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:
•Pass – This category includes loans that are all considered acceptable credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that meet or exceed industry standards.
•Watch – This category includes loans that warrant a higher-than-average level of monitoring to ensure that weaknesses do not cause the inability of the credit to perform as expected. These loans are not necessarily a problem due to other inherent strengths of the credit, such as guarantor strength, but have above average concern and monitoring.
•Special mention – This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset, or inadequately protect Busey’s credit position at some future date.
•Substandard – This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that Busey will sustain some loss if the deficiencies are not corrected.
•Substandard non-accrual – This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine.
All loans are graded at their inception. Commercial lending relationships that are $1.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $1.0 million are included in a portfolio review at least annually. Commercial loans greater than $0.35 million that have a grading of special mention or worse are typically reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more frequent review.

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 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 underlying collateral, less estimated costs to sell. Busey had $19.3 million and $6.1 million of collateral dependent loans secured by real estate or business assets as of December 31, 2024, and December 31, 2023, respectively.

Allowance for Credit Losses
Management estimates the ACL balance using relevant available information from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of Busey’s historical loss experience beginning in 2010. Due to the continued economic uncertainty in the markets in which the Company operates, Busey will continue to utilize a forecast period of 12 months with an immediate reversion to historical loss rates beyond this forecast period in its ACL estimate.
The following table summarizes 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 in other lending activities (dollars in thousands):

NOTE 10. 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 (dollars in thousands):

Weighted average rate for securities sold under agreements to repurchase | 2.63 | % |  | 3.26 | %

Term Loan
On May 28, 2021, Busey entered into a Second Amended and Restated Credit Agreement, pursuant to which Busey has access to (1) a $40.0 million revolving line of credit with an initial termination date of April 30, 2022, and (2) a $60.0 million Term Loan with a maturity date of May 31, 2026. The loans had an annual interest rate of 1.75% plus the one-month LIBOR rate. On April 30, 2022, the agreement was amended, effecting an extension of the termination date for the revolving line of credit to April 30, 2023, and providing for the transition from a LIBOR-indexed interest rate to a SOFR-indexed interest rate. Under the terms of the amendment, the annual interest rate for the loans was established at 1.80% plus the one-month forward-looking term rate based on SOFR. The agreement has subsequently been amended twice to extend the termination date for the revolving line of credit, which is currently April 30, 2025.
During the first quarter of 2024, Busey paid the full $30.0 million balance remaining on the Term Loan, at which time the Term Loan carried interest at a rate of 7.13%. As of December 31, 2024, there was no balance outstanding on the revolving credit facility. The revolving credit facility incurs a non-usage fee based on any undrawn amounts.
Short-Term Borrowings
Busey’s short-term borrowings may include loans maturing within one year of the loan origination date, as well as the current portion of long-term debt that is due within 12 months. Short-term borrowings are summarized as follows (dollars in thousands):

| As of December 31,

Subordinated Notes
On June 1, 2020, Busey issued $125.0 million of fixed-to-floating rate subordinated notes that mature on June 1, 2030. The subordinated notes, which qualify as Tier 2 capital for regulatory purposes, bear interest at an annual rate of 5.25% for the first five years after issuance and thereafter 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. Interest on the subordinated notes is payable semi-annually on each June 1 and December 1 during the five-year fixed-term, and thereafter on March 1, June 1, September 1, and December 1 of each year, commencing on September 1, 2025. The subordinated notes have an optional redemption in whole or in part on any interest payment date on or after June 1, 2025. The subordinated notes are unsecured obligations of the Company.
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 expected to be 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 “Note 2. Mergers and Acquisitions”), Busey acquired $4.0 million of 5.25% fixed-to-floating rate subordinated notes maturing December 4, 2030, which qualify as Tier 2 capital for regulatory purposes. Interest on the subordinated notes 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 expected to be the Three-Month Term SOFR (as defined in the subordinated notes), plus a spread of 497 bps from December 4, 2025. The subordinated notes have an optional redemption, in whole or in part, on or after December 4, 2025. At December 31, 2024, there was $0.1 million of fair value discount outstanding, to be accreted through the earliest optional redemption date.

NOTE 11. JUNIOR SUBORDINATED DEBT OWED TO UNCONSOLIDATED TRUSTS
Busey maintains statutory trusts for the sole purpose of issuing and servicing trust preferred securities and related trust common securities. Proceeds from such issuances were used by the trusts to purchase junior subordinated notes issued by Busey, which are the sole assets of each trust. Concurrent with the issuance of the trust preferred securities, Busey issued guarantees for the benefit of the holders of the trust preferred securities. The trust preferred securities are instruments that qualify and are treated as Tier 1 regulatory capital. Busey owns all of the common securities of each trust. The trust preferred securities issued by each trust rank equally with the common securities in right of payment, except that if an event of default under the indenture governing the notes has occurred and is continuing, the preferred securities will rank senior to the common securities in right of payment. Busey had $74.8 million and $72.0 million of junior subordinated debt owed to unconsolidated trusts at December 31, 2024, and 2023, respectively, maturing in 2033 through 2036. In connection with its acquisitions of Pulaski Financial Corp. in 2016 and M&M in 2024, Busey has acquired similar statutory trusts and the fair value adjustment is being accreted over their weighted average remaining lives, with a balance of $2.9 million and $2.6 million remaining to be accreted as of December 31, 2024, and 2023, respectively.
Busey’s trust preferred securities are subject to mandatory redemption, in whole or in part, upon repayment of the junior subordinated notes at par value at the stated maturity date or upon redemption. Each trust’s ability to pay amounts due on the trust preferred securities is solely dependent upon Busey making payments on the related junior subordinated notes. Busey’s obligations under the junior subordinated notes and other relevant trust agreements, in aggregate, constitute a full and unconditional guarantee by Busey of each trust’s obligations under the trust preferred securities issued by each trust. Busey has the right to defer payment of interest on the notes, in which case the distributions on the trust preferred securities will also be deferred, for up to five years, but not beyond the stated maturity date.
For regulatory capital purposes, current banking regulations allow for the inclusion in Tier 1 Capital of qualifying trust preferred securities issued prior to May 19, 2010, by bank holding companies with less than $15.0 billion of assets, but do not allow for additional Tier 1 Capital to be raised through the future issuance of trust preferred securities. As of December 31, 2024, 100% of the trust preferred securities qualified as Tier 1 Capital; however, once Busey reaches $15.0 billion in assets, its trust preferred securities will no longer quality as Tier 1 Capital.
NOTE 12. REGULATORY CAPITAL
First Busey and Busey Bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on Busey's Consolidated Financial Statements. Capital amounts and classification also are subject to qualitative judgments by regulators about components, risk weightings, and other factors.
Banking regulations identify five capital categories for insured depository institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. As of December 31, 2024 and 2023, all capital ratios of First Busey and Busey Bank exceeded well capitalized levels under the applicable regulatory capital adequacy guidelines. Management believes that no events or changes have occurred subsequent to December 31, 2024, that would change this designation.

Current Expected Credit Loss Model
On August 26, 2020, the FDIC and other federal banking agencies adopted a final rule which provided banking organizations that adopted CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital and to phase in the aggregate impact of the deferral on regulatory capital over a subsequent three-year period. Under this final rule, because Busey elected to use the deferral option, the regulatory capital impact of Busey’s transition adjustments recorded on January 1, 2020, arising from the adoption of CECL was deferred for two years. In addition, 25 percent of the ongoing impact of CECL on Busey’s ACL, retained earnings, and average total consolidated assets from January 1, 2020, through the end of the two-year deferral period, each as reported for regulatory capital purposes, has been added to the deferred transition amounts (“adjusted transition amounts”) and deferred for the two-year period. On January 1, 2022, at the conclusion of the two-year period, the adjusted transition amounts began to be phased-in for regulatory capital purposes at a rate of 25 percent per year, with the phased-in amounts included in regulatory capital at the beginning of each year.

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%, (2) Tier 1 capital to risk-weighted assets of at least 8.5%, and (3) total capital to risk-weighted assets of at least 10.5%.
Subsidiary Dividend Payments
First Busey Corporation’s ability to pay cash dividends to its stockholders and to service its debt is dependent on the receipt of cash dividends from its subsidiaries. Under applicable regulatory requirements, an Illinois state-chartered bank, such as Busey Bank, may not pay dividends in excess of its net profits. Busey Bank paid $100.0 million, $90.0 million, and $95.0 million in dividends to First Busey Corporation during the years ended December 31, 2024, 2023, and 2022, respectively.

Busey provides retirement benefits under its 401(k) Plan. All Busey associates who meet certain age requirements are eligible to participate in the 401(k) Plan. There is no waiting period for participation in the 401(k) Plan.

Plan participants may elect to make traditional and/or Roth 401(k) contributions, up to the annual deferral and catch-up limits established by the Internal Revenue Service.
Busey supplements participant contributions by making safe harbor matching and discretionary profit-sharing contributions to the 401(k) Plan.
Safe Harbor Match
Busey makes safe harbor matching contributions to the 401(k) Plan equal to 100% of the first 3% of eligible participant compensation contributed to the plan and 50% of the next 2% of eligible participant compensation contributed to the plan. The rights of participants in safe harbor matching contributions vest immediately.

Busey has granted RSU, PSU, and DSU awards under the terms of the 2020 Equity Plan. Upon vesting and delivery, shares are expected, though not required, to be issued from treasury stock.
A description of RSU, PSU, and DSU awards granted in 2024 under the terms of the 2020 Equity Plan is provided below. A description of RSU, PSU, and DSU awards granted in 2023 and 2022 under the terms of the 2020 Equity Plan can be found in Busey’s Annual Reports for the years ended December 31, 2023, and 2022, respectively.
Busey issued 163,387 treasury shares in conjunction with the settlement of RSUs, PSUs, and DSUs in 2024. The difference between the number of shares issued and the number of vested units is due to shares issued under a net share settlement option. There were 1,326,314 shares available for issuance under the 2020 Equity Plan as of December 31, 2024.
RSU Awards
Busey grants RSU awards to members of management periodically throughout the year. RSU awards are stock-based awards for which vesting is conditional upon meeting established service criteria. Each RSU is equivalent to one share of Busey’s common stock. Busey’s RSUs have requisite service periods ranging from one year to five years, and are subject to accelerated vesting upon eligible retirement from Busey. Recipients earn quarterly dividend equivalents on their respective RSUs, which entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances.
On March 20, 2024, under the terms of the 2020 Equity Plan, Busey granted 189,179 RSUs to members of management. The grant date fair value of the award was $4.4 million, which will be recognized as compensation expense over the requisite service period ranging from one year to five years. The terms of these awards included an accelerated vesting provision upon eligible retirement from Busey, after a one-year minimum requisite service period. Subsequent to the requisite service period, the awards will become 100% vested.
On May 22, 2024, under the terms of the 2020 Equity Plan, Busey granted 12,864 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 of three years. The terms of these awards included an accelerated vesting provision upon eligible retirement from Busey, after a one-year minimum requisite service period. Subsequent to the requisite service period, the awards will become 100% vested.
A summary of changes in Busey’s RSU awards for the year ended December 31, 2024, is as follows:

RSU Awards |  | Shares |  | Weighted- Average Grant Date Fair Value

PSU Awards
Busey grants PSU awards to members of management periodically throughout the year. PSU awards are stock-based awards for which vesting is conditional upon meeting established performance criteria for the applicable performance period and remaining employed through the end of such performance period. Each PSU is equivalent to one share of Busey’s common stock. The number of PSUs that ultimately vest will be determined based on the extent to which 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 20, 2024, under the terms of the 2020 Equity Plan, Busey granted a target of 94,604 PSUs with a maximum award of 151,366 units. The actual number of units issued at the vesting date could range from 0% to 160% of the initial grant, depending on attaining a relative total stockholder return performance goal. The grant date fair value of the award, calculated using the Geometric Brownian Motion Model, was $2.0 million, which will be recognized in compensation expense over the performance period ending December 31, 2026.
On March 20, 2024, under the terms of the 2020 Equity Plan, Busey granted a target of 94,604 PSUs with a maximum award of 151,366 units. The actual number of units issued at the vesting date could range from 0% to 160% of the initial grant, depending on attaining an adjusted return on average tangible common equity performance goal. The grant date fair value of the award was $2.2 million, which will be recognized in compensation expense over the performance period ending December 31, 2026. The actual amount of compensation expense recognized 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 year ended December 31, 2024, is as follows:

PSU Awards |  | Shares 1 |  | Weighted- Average Grant Date Fair Value
Nonvested at December 31, 2023 |  | 341,700 |  |  | $ | 22.67 |

DSU Awards
Busey grants DSU awards to its non-employee directors. DSU awards are stock-based awards with a deferred settlement date. Each DSU is equivalent to one share of Busey’s common stock. DSUs vest over a one-year period following the grant date. Under the 2020 Equity Plan, DSUs are generally subject to the same terms as RSUs, except that following vesting of DSUs, settlement occurs within 30 days following the earlier of separation from the board or a change in control of the Company. After vesting and prior to delivery, DSUs will continue to earn dividend equivalents.

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. Where a loss is believed to be reasonably possible, but not probable, or the loss cannot be reasonably estimated, as is the case with this matter, no accrual is required. It is reasonably possible that this matter could require 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 December 31, 2024. If the likelihood of potential liabilities elevates, requiring an accrual, the potential future liabilities could be material in the period(s) in which they are recorded.
NOTE 19. DERIVATIVE FINANCIAL INSTRUMENTS
Busey utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. Additionally, Busey enters into derivative financial instruments, including interest rate lock commitments issued to residential loan customers for loans that will be held for sale; forward sales commitments to sell residential mortgage loans to investors; and interest rate swaps, risk participation agreements, and foreign currency exchange contracts with customers and other third parties. See “Note 20. Fair Value Measurements” for further discussion of the fair value measurement of such derivatives.
To secure its obligations under derivative contracts, Busey pledged cash and held collateral as follows (dollars in thousands):

| As of December 31,
| 2024 |  | 2023
Cash pledged to secure obligations under derivative contracts | $ | 21,900 |  |  | $ | 34,210 |
Collateral held to secure obligations under derivative contracts | 20,260 |  |  | 19,280 |

Derivative Instruments Designated as Hedges
Busey entered into derivative instruments designated as cash flow hedges. For a derivative instrument that is designated and qualifies as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of OCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Changes in fair value of components excluded from the assessment of effectiveness are recognized in current earnings.

Interest Rate Swaps Designated as Cash Flow Hedges
Interest rate swaps with notional amounts totaling $500.0 million as of December 31, 2024, and $350.0 million as of December 31, 2023, 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, in 2024 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. During 2024 an interest rate swap to hedge the risks of variability in cash flows for future interest payments attributable to changes in the 3-month CME Term SOFR benchmark interest rate on Busey’s junior subordinated debt owed to unconsolidated trusts (“Debt Swap”) matured. Changes in fair value were recorded net of tax in OCI.

Derivative Instruments Not Designated as Hedges
Interest Rate Swaps Not Designated as Hedges
Busey may offer derivative contracts to its customers in connection with their risk management needs. Busey manages the risk associated with these contracts by entering into equal and offsetting derivative agreements with a third-party dealer. These contracts supported variable rate, commercial loan relationships totaling $719.2 million and $663.1 million as of December 31, 2024 and 2023, respectively. 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.

Risk Participation Agreements
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 entered into a risk participation agreement under which Busey sold credit risk participation, receiving an up-front fee from a counterparty in exchange for accepting a portion of the counterparty’s credit exposure. This agreement matured on June 30, 2024. The swap customer did not default on its obligations, and Busey was not required to make a payment to the counterparty of the risk participation agreement.
Notional amounts of the risk participation agreements reflect the participating banks’ pro-rata shares of the derivative instruments, consistent with their shares of the related participated loans. The risk participation agreements mature between August 2026 and January 2029, and are summarized as follows (dollars in thousands):

Mortgage Banking Derivatives
Interest Rate Lock Commitments
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 Consolidated Balance Sheets, 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.
Forward Sales Commitments
Busey economically hedges mortgage loans held for sale and interest rate lock commitments issued to its residential loan customers related to loans that will be held for sale by obtaining corresponding forward sales commitments with an investor to sell the loans at an agreed-upon price at the time the interest rate locks are issued to the customers. Forward sales commitments that meet the definition of derivative financial instruments under ASC Topic 815 “Derivatives and Hedging” are carried at their fair values in other assets or other liabilities on the Consolidated Balance Sheets. While such forward sales commitments generally served as an economic hedge to mortgage loans held for sale and interest rate lock commitments, Busey did not designate them for hedge accounting treatment. Changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Gains or losses are recognized on these mortgage banking derivative instruments in earnings; however, because loans held for sale are carried at LOCOM, any corresponding increase in the fair value of loans held for sale will not be recognized in earnings until the loans are sold, at which time the increase is factored into the calculated gain on sale. Decreases in the market value of loans held for sale is recognized in earnings at each measurement period.

NOTE 20. FAIR VALUE MEASUREMENTS
The fair value of an asset or liability is the price that would be received by selling that asset or paid in transferring that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820 “Fair Value Measurement” establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:
•Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.
•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.
•Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.
A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to Busey’s assets and liabilities that are carried at fair value.
In general, fair value 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 Liabilities Measured at Fair Value on a Recurring Basis
Debt Securities Available for Sale
Debt securities classified as available for sale are reported at fair value, 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.

Table of Contents Contents of Item 8. Financial Statements & Supplementary Data
FIRST BUSEY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
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.
Equity Securities
Equity securities are reported at fair value, which is estimated using Level 1 or Level 2 inputs. Fair value measurements of mutual funds, when held, are estimated using unadjusted quoted prices in active markets for identical assets at the measurement date and are classified as Level 1. Fair value measurements of stock use quoted prices for identical or similar assets in markets that are not active and are classified as Level 2.
Derivative Assets and Derivative Liabilities
Busey’s derivative assets and derivative liabilities are reported at fair value, which is measured using Level 2 or Level 3 inputs. Derivative balances are included in other assets or other liabilities on the Consolidated Balance Sheets, and consist of interest rate swaps and risk participation agreements where there is no significant deterioration in the counterparties (loan customers) credit risk since origination of the interest rate swap or risk participation agreement, as well as mortgage banking derivatives, including interest rate lock commitments and forward sales commitments.
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. For purposes of potential valuation adjustments to Busey’s derivative positions, Busey evaluates the credit risk of its counterparties as well as its own credit risk. Accordingly, Busey has considered factors such as the likelihood of default, expected loss given default, net exposures, and remaining contractual life, among other things, in determining if any estimated fair value adjustments related to credit risk are required. Busey reviews counterparty exposure quarterly, and when necessary, appropriate adjustments are made to reflect the exposure. No changes in counterparty credit were identified.
Due to the significance of unobservable inputs, derivative assets 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).
Loans Evaluated Individually
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.
Bank Property Held for Sale
Bank property held for sale represents certain banking center office buildings which Busey has closed and consolidated with other existing banking centers. Bank property held for sale is measured at the lower of amortized cost or estimated fair value less estimated costs to sell, and is included in premises and equipment, net on the Consolidated Balance Sheets. Fair values were based upon discounted appraisals or real estate listing prices. Due to the significance of unobservable inputs, fair values of all bank property held for sale have been classified as Level 3.
The following tables summarize assets and liabilities measured at estimated fair value on a non-recurring basis, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

NOTE 23. OPERATING SEGMENTS AND RELATED INFORMATION
Busey’s reportable segments are determined by its chief executive officer, Van A. Dukeman, who is the designated chief operating decision maker. Busey is organized into three reportable operating segments: Banking, Wealth Management, and FirsTech. These operating segments are strategic business units that are separately managed, as they offer different products and services and have different marketing strategies.
To evaluate segment performance and make informed decisions regarding the allocation of capital and personnel to the segments, the chief operating decision maker reviews each segment’s actual revenues, consisting of net interest income plus noninterest income, and net income against budgeted revenues and net income on a monthly basis. This process enables the Company to (1) determine the cost and availability of funds within each business segment, (2) assess the profitability of a specific business segment by aligning relevant costs with revenues, and (3) evaluate each business segment in a way that reflects its economic impact on consolidated earnings.
Banking
The Banking operating segment provides a full range of banking services to individual and corporate customers through First Busey Corporation’s wholly-owned bank subsidiary, Busey Bank, with 62 banking centers in Illinois; the St. Louis, Missouri, metropolitan area; southwest Florida; and Indianapolis, Indiana.
Banking services offered to individual customers include customary types of demand and savings deposits, money transfers, safe deposit services, individual retirement accounts and other fiduciary services, automated teller machines, and technology-based networks, as well as a variety of loan products including residential real estate, home equity lines of credit, and consumer loans. Banking services offered to corporate customers include commercial, CRE, real estate construction, and agricultural loans, as well as commercial depository services such as cash management.
Wealth Management
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. Services are provided through Busey Capital Management, Inc., a wholly-owned subsidiary of Busey Bank, and Busey Wealth Management, a division of Busey Bank.
Wealth management services tailored to individuals include trust and estate advisory services and financial planning. Business services include business succession planning and employee retirement plan services. Services for foundations include investment strategy consulting and fiduciary services.

ITEM 9A. 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 December 31, 2024, 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 December 31, 2024, 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 December 31, 2024, 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.
MANAGEMENT’S REPORT ON INTERNAL CONTROL OVER FINANCIAL REPORTING
Busey’s management is responsible for establishing and maintaining adequate internal control over financial reporting. Busey’s internal control over financial reporting is a process designed under the supervision of Busey’s Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of Busey’s Consolidated Financial Statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.
As of December 31, 2024, management assessed the effectiveness of Busey’s internal control over financial reporting based on the criteria for effective internal control over financial reporting established in “Internal Control—Integrated Framework,” issued by the COSO in 2013. Based on this assessment, management determined that Busey maintained effective internal control over financial reporting as of December 31, 2024, based on the COSO criteria.
RSM US LLP, an independent registered public accounting firm that audited Busey’s Consolidated Financial Statements included in this Annual Report, has issued an audit opinion on the effectiveness of Busey’s internal control over financial reporting as of December 31, 2024. The report, which expresses an unqualified opinion on the effectiveness of Busey’s internal control over financial reporting as of December 31, 2024, is included in this Item under the heading “Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting.”

Report of Independent Registered Public Accounting Firm
To the Stockholders and the Board of Directors of First Busey Corporation and Subsidiaries
Opinion on the Internal Control Over Financial Reporting
We have audited First Busey Corporation and Subsidiaries' (the Company) internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2024, based on criteria established in Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission in 2013.
We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2024 and 2023, the related consolidated statements of income, comprehensive income (loss), stockholders' equity and cash flows for each of the three years in the period ended December 31, 2024, and the related notes to the consolidated financial statements and our report dated February 27, 2025 expressed an unqualified opinion.
Basis for Opinion
The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.
We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting
A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company's assets that could have a material effect on the financial statements.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
