Acquisition of Merchants and Manufacturers Bank Corporation Planned for The Second Quarter of 2024
On November 27, 2023, First Busey Corporation announced the signing of a definitive agreement with M&M, pursuant to which Busey will acquire M&M and its wholly-owned subsidiary, M&M Bank, through a merger transaction. This partnership will add M&M’s Life Equity Loan® products to Busey’s existing suite of services, and expand Busey’s presence in the Chicago Metropolitan Statistical Area.
Under the terms of the merger agreement, M&M’s stockholders will have the right to receive for each share of M&M common stock, at the election of each stockholder and subject to proration and adjustment, either (1) $117.74 in cash, (2) 5.7294 shares of Busey common stock, or (3) mixed consideration of $34.55 in cash and 4.0481 shares of Busey common stock, with total consideration to consist of approximately 71% stock and 29% cash. Based upon Busey’s 20‑day volume-weighted average closing price as of November 24, 2023, the aggregate implied transaction value is approximately $41.6 million.
The merger is expected to be finalized in the second quarter of 2024, subject to customary closing conditions and required approvals, including regulatory approvals and the approval of M&M’s stockholders. It is anticipated that M&M Bank will be merged with and into Busey Bank at a date following the completion of the merger.

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, 2023, the most recent report available, out of 366 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:

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 bank regulatory 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 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 bank regulatory agencies issued under them, affect, among other things, the scope of Busey’s business; the kinds and amounts of investments First 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 to merge, consolidate and acquire; dealings with First Busey’s and Busey Bank’s insiders and affiliates; and Busey’s payment of dividends.

Table of Contents Contents of Item 1. Business
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 systemically important financial service providers (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.
The supervisory framework for U.S. banking organizations subjects banks and bank holding companies to regular examination by their respective regulatory 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 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 in the introduction above, the Dodd-Frank Act included a number of requirements that 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 Dodd-Frank regulations and reporting requirements 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 basis points 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 entity 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.
First Busey Corporation | 2023 — 12

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 entities (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 entity’s trading activities and to clarify and amend certain definitions, requirements, and exemptions. Banking entities 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 regulatory agency, the FDIC.
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 generally are required to hold more capital than other businesses. These requirements directly affects 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 banks prior to the crisis was insufficient to absorb losses during periods of severe stress.
First Busey Corporation | 2023 — 13

Table of Contents Contents of Item 1. Business
Capital Levels
Banks have been required to hold minimum levels of capital based on guidelines established by the bank regulatory agencies since 1983. The minimums have been expressed in terms of ratios of “capital” divided by “total assets.” Beginning in 1989, capital guidelines for U.S. banks have been based upon international capital accords, known as “Basel” rules, 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. bank regulatory agencies on an interagency basis. The 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 agreement on a strengthened set of capital requirements for banking organizations around the world, known as Basel III, 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 in place previously. The Basel III Rule is applicable to all banking organizations that are subject to minimum capital requirements, including federal and 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 Basel I in assigning assets to risk-weight categories, it significantly increases the categories and adds conditions. Risk weights were established as high as 250% for certain commercial real estate exposures, and higher for certain derivatives. The assignment of risk weights continues to be under review by the banking agencies and has culminated in an initiative called “Basel III: Endgame,” which, as proposed, would only apply to banks with $100 billion in assets or more and would not impact Busey.
Minimum Capital Ratio Requirements
Basel III 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 institution’s Common Equity Tier 1 Capital.
The Basel III Rule requires minimum capital ratios as follows:
•A ratio of Common Equity Tier 1 Capital equal to 4.5% of risk-weighted assets;
First Busey Corporation | 2023 — 14

Table of Contents Contents of Item 1. Business
•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, institutions 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.” Bank regulatory agencies uniformly encourage banks 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, 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 FDIC and 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;
•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, 2023: (1) Busey Bank was not subject to a directive from the FDIC to increase its capital, and (2) Busey Bank was well-capitalized, as defined by FDIC regulations. As of December 31, 2023, First Busey had regulatory capital in excess of the Federal Reserve’s requirements and met the requirements to be well-capitalized. First Busey also is in compliance with the capital conservation buffer.

Prompt Corrective Action
The concept of an institution being “well-capitalized” is part of a regulatory enforcement regime that provides the federal banking regulators 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 institution 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 an institution is assigned, the regulators’ 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 we 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.
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 U.S. 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 company has a period of time in which to achieve compliance, but during the period of noncompliance, the Federal Reserve may place any limitations on the company it believes to be appropriate. Furthermore, if the Federal Reserve determines that a financial holding company’s subsidiary bank has not received a satisfactory CRA rating, that 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 bank regulator. “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 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.
First Busey Corporation | 2023 — 17

Table of Contents Contents of Item 1. Business
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, institutions that seek the freedom to pay dividends have to 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 banks, reflecting recognition by the bank regulatory agencies and 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.
The interagency guidance recognized three core principles. Effective incentive plans should: (1) provide employees 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 addresses 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. Smaller banking organizations, like First Busey, that use incentive compensation arrangements are expected to be less extensive, formalized, and detailed than those of the larger banks.
Monetary Policy
The monetary policy of the Federal Reserve has a significant effect on the operating results of financial or bank holding companies and their subsidiaries, which was exacerbated by the COVID-19 pandemic. 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.
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 by authorizing 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 legislation also directed the Federal Reserve to promulgate rules prohibiting excessive compensation paid to executives of bank holding companies, regardless of whether such companies are publicly traded.
Supervision and Regulation of Busey Bank
General
Busey Bank is an Illinois-chartered bank. Its deposit accounts are insured by the DIF 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. Busey Bank is also regulated by the FDIC, designated by federal law as the primary federal regulator of insured state banks that, like Busey Bank, are not members of the Federal Reserve System.
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 currently range from 1.5 basis points to 30 basis points on an annualized basis. However, the maximum rate is 18 basis points for financial institutions in the top two categories of examination composite ratings.
At least semi-annually, the FDIC updates its loss and income projections for the DIF and, if needed, increases or decreases the assessment rates, following notice and comment on proposed rule making. For this purpose, the reserve ratio is the DIF 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 the semi-annual update in June 2022, the FDIC projected that the reserve ratio was at risk of not reaching the statutory minimum of 1.35% by September 30, 2028, statutory deadline. Based on this update, the FDIC approved an increase in initial base deposit insurance assessment rate schedules uniformly by two basis points, applicable to all insured depository institutions. The increase was effective on January 1, 2023, applicable to the first quarterly assessment period of 2023 (January 1 through March 31, 2023).
In addition, because the total cost of the failures of Silicon Valley Bank and Signature Bank was approximately $16.3 billion, the FDIC adopted a special assessment for banks having deposits above $5 billion, at an annual rate of 13.4 basis points beginning with the first quarterly assessment period of 2024 (January 1 through March 31, 2024) with an invoice payment date of June 28, 2024, and 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 was not subject to 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, 2023, Busey Bank paid supervisory assessments to the DFPR totaling approximately $0.7 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.
The primary role of liquidity risk management is 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, and will not, apply to Busey Bank, management continues to review its liquidity risk management framework in light of regulatory and industry developments.
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 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 a 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 FDIC and the DFPR may prohibit the payment of dividends by Busey Bank if either or both determine such payment would constitute an unsafe or unsound practice. In addition, under the Basel III Rule, institutions that seek the freedom to pay dividends have to maintain 2.5% in Common Equity Tier 1 Capital attributable to the capital conservation buffer.

State Bank Investments and Activities
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 DIF. These restrictions have not had, and are not currently expected to have, a material impact on the operations of Busey Bank.
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. While 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 regulator is required to issue an order directing the institution to cure the deficiency. Until the deficiency cited in the regulator’s order is cured, the regulator 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 the regulator deems appropriate under the circumstances. Noncompliance with safety and soundness may also constitute grounds for other enforcement action by the federal bank regulatory agencies, including cease and desist orders and civil money penalty assessments.

Table of Contents Contents of Item 1. Business
During the past decade, bank regulatory 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 agencies have identified a spectrum of risks facing a banking institution including, but not limited to, credit, market, liquidity, operational, legal, and reputational risk. The key risk themes identified by the Company 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.
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 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.
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.
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 regulators regularly assess Busey Bank’s record of meeting the credit needs of its communities in dedicated examinations. Applications for acquisitions are affected by the evaluation of Busey Bank’s effectiveness in meeting its CRA requirements.
First Busey Corporation | 2023 — 22

Table of Contents Contents of Item 1. Business
On October 24, 2023, the bank regulatory agencies issued a final rule to strengthen and modernize CRA regulations (the "CRA Rule"), some of which is effective beginning April 1, 2024. 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 bank regulatory 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. Management of Busey Bank is assessing the impact of the CRA Rule on its CRA lending and investment activities in its markets.
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
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.
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. 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, federal banking agencies issued a statement 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. Federal bank agencies 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, 2023, 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 financial crisis, many new 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 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.
Over the last several years, the CFPB has taken a proactive, multi-front approach to protect consumers from excessive overdraft and non-sufficient funds fees. This includes proposed rules, interpretive opinions and enforcement actions. In January 2024, this included a proposed rule that would prohibit non-sufficient funds fees on transactions declined in real time (debit card purchases, ATM withdrawals, and peer-to-peer payments) and a proposal to subject overdrafts on bank accounts to disclosure rules applicable to other kinds of credit. The actions proposed or taken thus far by the CFPB affects financial institutions, like Busey Bank, with more than $10 billion in assets. Busey Bank’s management expects continued developments in this area that will impact its overdraft practices and may result in a decrease in fee income.
The CFPB’s rules have an impact on Busey Bank’s operations, including by increasing compliance costs and potentially negatively affecting revenue.

ITEM 1A. RISK FACTORS
This section highlights the risks management believes could adversely affect our financial performance. Additional possible risks that could affect Busey adversely and cannot be predicted may arise at any time. Other risks that are immaterial at this time may also have an adverse impact on our 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 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.
Uncertainty regarding economic conditions may result in changes in consumer and business spending, borrowing, and savings habits. Downturns in the markets where our banking operations occur could result in a decrease in demand for our 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 our loans, financial condition, and results of operations.
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.
While high market volatility is not expected, managing “higher for longer” interest rates can put pressure on Busey’s deposit rates and liquidity.
Prolonged periods of high-interest rates pose several risks to Busey. Offering higher interest rates to attract deposits elevates the cost of funding. Concurrently, Busey may experience increased interest expenses on its borrowings and debt. Moreover, high-interest rates can deter borrowing and spending, potentially reducing demand for loans and impacting liquidity. In such an environment, heightened competition for deposits may necessitate maintaining competitive interest rates to retain and attract customers. Interest rates are sensitive to many factors beyond

Busey’s control, including general economic conditions and policies of various governmental and regulatory agencies, such as the FOMC.
In March 2022, the Federal Reserve initiated a series of interest rate hikes to combat inflation. After 11 successive increases, as of December 2023, the fed funds target range stood at 5.25% - 5.5%, reaching its highest level since 2001. Throughout 2023, the health of the U.S. economy improved, surpassing expectations and reducing likelihood of a recession. Despite recent positive economic indicators, certain risks persist, including record-high U.S. credit card debt and increasing delinquencies in mortgages, auto loans, and credit cards. In December 2023, the FOMC projected U.S. GDP growth to slow to 1.4% in 2024. The Federal Reserve aims for a soft landing by maintaining its 2023 plan into 2024, hoping that sustained elevated interest rates will cool the economy and alleviate inflationary pressures. These effects, combined with other considerations, could have a material impact on our business, financial condition, liquidity, and results of operations.
In the context of the multifaceted factors influencing the U.S. economy, uncertainties loom over the persistence of inflation, exacerbated by geopolitical tensions such as the Russia-Ukraine and Israel-Hamas conflicts. Additionally, unforeseen disruptions in the global energy market and challenges in the tight labor market and supply chain add to the complexity. Earlier in the year, there was a substantial risk that central banks, including the Federal Reserve, might raise interest rates excessively, potentially constraining economic growth and triggering a recession. However, as inflation decelerated throughout the year and market data hinted at easing housing price pressures, there is potential for a positive impact on loan demand.
Ongoing monetary policy, including the persistence of elevated interest rates, significantly impacts not only the interest earned from loans and investment securities, as well as the interest paid on deposits and borrowings, but also influences Busey's ability to originate loans and attract deposits, and the fair value of its financial assets and liabilities. As interest rates remain elevated, intensified competition for deposits may persist, potentially altering Busey’s funding mix and cost of funding. In addition to the aforementioned risks, Busey acknowledges the potential challenges arising from falling interest rates. For example, a decrease in interest rates may adversely affect Busey’s floating rate loan portfolios, leading to a reduction in interest income. Any substantial, unexpected, and prolonged changes in market interest rates, even if they are maintained at a high level, could still have a material adverse effect on Busey’s business, financial condition, and results of operations.
The combination of factors such as changes in interest rates, an adverse credit quality outlook, economic uncertainties, and geopolitical events can contribute to increased fluctuations in market values.
The market value of investments may be affected by factors other than the underlying performance of the servicer of the securities or the mortgages underlying the securities, such as changes in the interest rate environment, negative trends in the residential and commercial real estate markets, ratings downgrades, adverse changes in the business climate, and a lack of liquidity in the secondary market for certain investment securities. On a quarterly basis, we formally evaluate investments and other assets for impairment indicators. Reduction in the value, or impairment of our investment securities, can impact our earnings and common stockholders' equity. Changes in market interest rates can affect the value of these investment securities, with increasing interest rates generally resulting in a reduction of value. Although the reduction in value from temporary increases in market rates does not affect our income until the security is sold, it does result in an unrealized loss recorded in OCI that can reduce our common stockholders’ equity. Further, we may have to record provision expense to establish an allowance for credit losses on our carried at fair value debt securities, and we must periodically test our investment securities for other-than-temporary impairment in value. In assessing whether the value of investment securities is impaired, we consider the length of time and extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability to retain our investment in the security for a period of time sufficient to allow for any anticipated recovery in fair value in the near term.

Table of Contents Contents of Item 1A. Risk Factors
Ongoing inflation trends pose potential risks to our business and operational performance.
Elevated inflation poses potential risks to our business and operational performance, impacting consumer purchasing power and necessitating careful consideration of potential effects on various facets of our operations. Successful measures by the Federal Reserve in stabilizing inflation through interest rate hikes could mitigate some of these risks and positively influence loan demand and mitigate challenges to our clients' ability to repay indebtedness. It is also possible that governmental responses to the current inflation environment, such as changes to monetary and fiscal policy that are too strict, or the imposition or threatened imposition of price controls, could adversely affect our business. The duration and severity of the current inflationary period cannot be estimated with precision.
REGULATORY AND LEGAL RISKS
Election-year variables bring additional levels of uncertainty.
The evolving landscape of legislative and regulatory actions, influenced by election cycles, introduces an additional layer of uncertainty for our operations. Elections can precipitate changes in government policies and regulations across various industries, potentially impacting our business. Uncertainty regarding potential changes in regulations or policies related to our industry may lead to increased costs of doing business and operational challenges. Economic conditions, including interest rates, inflation, and consumer spending, may be influenced by shifts in government leadership and policies, affecting our ability to maintain historical growth rates.
Furthermore, the election process often introduces market volatility, impacting financial markets, currency exchange rates, and commodity prices. This volatility may pose risks to our financial performance, cost of capital, and access to funding.
The outcomes of elections may directly affect our industry, influencing regulatory frameworks and industry dynamics. Shifts in political power may shape the competitive landscape, impacting market share and pricing strategies. Unfavorable changes in industry-specific regulations could result in increased compliance costs and operational challenges. Political events, including elections, can influence consumer and investor sentiment, affecting demand for our products and services and impacting investor confidence, which may influence our stock price and access to capital.
In addition to these challenges, and the added uncertainty related to potentially increased regulation, the financial services industry in recent years has faced more intense scrutiny from regulatory agencies in the examination process and more aggressive enforcement of regulations on both the federal and state levels, particularly with respect to mortgage-related practices; fee-based products and other consumer compliance matters; and compliance with the Bank Secrecy Act, anti-money laundering laws, and the USA PATRIOT Act, which focuses on money laundering in the form of terrorist financing. Federal law grants substantial enforcement powers to financial services’ regulators including, among other things, the ability to assess significant civil or criminal monetary penalties, fines, or restitution; to issue cease and desist orders; and to initiate injunctive actions against banking organizations. These enforcement actions may be initiated for violations of laws or regulations and for unsafe or unsound practices. If Busey were the subject of an enforcement action, it could have an adverse impact on the Company.
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.
Busey has grown steadily over the past several years, increasing in size through both organic growth and strategic acquisitions. As financial institutions grow, so do the expectations of regulatory agencies regarding the financial institution’s ability to control for increasingly complex and sophisticated business operations. Certain regulations and laws have embedded asset thresholds that change regulatory expectations, have different financial statement impacts, require different committee and management compositions, or enhance certain reporting

requirements. For example, as further discussed in the Supervision and Regulation section, the Dodd-Frank Act included a number of requirements that trigger when a banking entity crosses over $10 billion in assets.
Beginning on July 1, 2022, Busey became subject to the Durbin Amendment. The Durbin Amendment requires the Federal Reserve to establish a maximum permissible interchange fee for many types of debit transactions, which reduced Busey’s fee income during the second half of 2022 and throughout 2023. Further in August 2022, Busey became subject to oversight of the CFPB for consumer transactions. As regulatory expectations, scrutiny, and reporting requirements continue to increase, Busey’s operations and strategies may be affected.
Regulatory change in the areas of cybersecurity and privacy are expected to continue to evolve. Multiple regulators have released updated cyber notification requirements across Busey’s regulatory footprint that may lead to increased regulatory scrutiny and potentially increased costs. Additionally, Busey’s expansion into regions with heightened privacy requirements or passage of privacy legislation within the regions in which Busey operates may impose additional compliance burdens. These changes could necessitate adapting Busey’s practices to meet heightened privacy standards. Failure to comply with these regulations may result in financial penalties, reputational harm, and legal consequences.
Laws impacting cannabis-related businesses in Illinois and other states 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 to legally purchase marijuana for recreational use from licensed dispensaries. Further, in November 2022 voters in Missouri approved a ballot initiative to legalize recreational use of cannabis. 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 is taking 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.
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.
Many aspects of our business and operations involve the risk of legal liability, and in some cases we or our subsidiaries have been named or threatened to be named as defendants in various lawsuits arising from our business activities. In addition, companies in our industry are frequently the subject of governmental and self-regulatory agency information-gathering requests, reviews, investigations, and proceedings. The results of such proceedings could lead to significant civil or criminal penalties, including monetary penalties, damages, adverse judgments, settlements, fines, injunctions, restrictions on the way in which we conduct our business, or reputational harm.
Although we establish accruals for legal proceedings when information related to the loss contingencies represented by those matters indicates both that a loss is probable and that the amount of loss can be reasonably estimated, we do not have accruals for all legal proceedings where we face a risk of loss. In addition, due to the inherent subjectivity of the assessments and unpredictability of the outcome of legal proceedings, amounts accrued may not represent the ultimate loss to us from the legal proceedings in question. Accordingly, our ultimate losses may
First Busey Corporation | 2023 — 38

Table of Contents Contents of Item 1A. Risk Factors
be higher, and possibly significantly so, than the amounts accrued for legal loss contingencies, which could adversely affect our financial condition and results of operations.
See “Note 16. Outstanding Commitments and Contingent Liabilities” in the Notes to the Consolidated Financial Statements for information regarding an inquiry from the ISOS, pursuant to which the ISOS asked for additional information regarding certain of our 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 effect on Busey’s results of operations and financial condition.
There are risks in making any loan, including risks inherent in dealing with individual borrowers, risks of nonpayment, risks resulting from uncertainties as to the future value of collateral and cash flows available to service debt, and risks resulting from economic and market conditions. In general, these risks have increased as a result of the recent increases in prevailing interest rates and uncertainties associated with inflation, which have potentially increased the risk of a near-term decline in growth or an economic downturn. Busey attempts to reduce its credit risk through loan application approval procedures, monitoring the concentration of loans within specific industries and geographic locations, and periodic independent reviews of outstanding loans by its loan review and audit departments as well as external parties. Credit risk related to the increasing interest rates are monitored through loan stress testing performed internally at the borrower level and by external parties for the portfolio-level analyses. However, while such procedures help reduce risks, they cannot be expected to completely eliminate Busey’s credit risks. Borrowers may experience difficulties in repaying their loans for any of a variety of reasons resulting in a rise in the level of nonperforming loans, charge-offs, delinquencies, and/or a need for increases in the provision for credit losses.
Busey estimates and establishes the ACL and maintains it at a level considered adequate by management to absorb probable credit losses based on a continual analysis of Busey’s portfolio and market environment. The ACL represent Busey’s estimate of probable losses in the portfolio at each balance sheet date and is based upon management judgments as well as forward-looking information and forecasts. Any failure of these judgments or forecasts could negatively affect our results of operations and financial condition. Although management believes the ACL is adequate to absorb losses on existing loans that may become uncollectible, management cannot guarantee that additional provisions for credit losses will not be required in the future.
Non-performing assets take significant time to resolve and adversely affect Busey’s results of operations and financial condition and could result in further losses in the future.
Busey's net income is impacted by non-performing assets in several ways, presenting challenges amid both rising and stable higher interest rate environments. While Busey incurs interest expense to finance non-performing assets, it does not record interest income on non-accrual loans or other real estate owned. This lack of interest income negatively impacts Busey's overall income and returns on assets and equity. Additionally, loan administration costs rise, contributing to an adverse impact on Busey's efficiency ratio. When Busey acquires collateral in foreclosures and similar proceedings, it must mark the collateral to its current fair market value, potentially resulting in losses when compared to the outstanding loan balance. Non-performing loans and other real estate owned elevate Busey’s risk profile and influence the regulatory capital deemed appropriate. The resolution of non-performing assets demands significant time commitments from management, potentially affecting their ability to fulfill other responsibilities. Credit leaders monitor signs of stress in borrowers, particularly those susceptible to the effects of both gradual and rapid increases in interest rates. However, default risk may arise from events or circumstances that are difficult to detect, such as fraud, or difficult to predict, such as catastrophic events affecting certain industries. Therefore, we cannot assure you that such monitoring procedures will reduce these credit risks.
First Busey Corporation | 2023 — 39

Table of Contents Contents of Item 1A. Risk Factors
Concentrations of credit and market risk could increase the potential for significant losses.
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. A significant portion of Busey’s loan portfolio is made up of commercial, commercial real estate, and retail real estate loans. Because payments on such loans are often dependent on the successful operation of the borrower involved, repayment of such loans is often more sensitive than other types of loans to adverse conditions in the general economy. For example, the cumulative effects of decreased economic activity, changes in the economy and overall business environment, labor availability shortages, and supply chain constraints which began as a result of the COVID-19 pandemic, but have continued due to inflationary concerns and significant increases in the interest rate, have adversely affected commercial loans, and we expect this trend to continue for certain portions of our loan portfolio, depending on the strength and speed of economic recovery and other factors, particularly if general economic conditions worsen.
Busey’s commercial loans are made primarily based on the identified cash flow of the borrower and secondarily on the underlying collateral provided by the borrower. Credit support provided by the borrower for most of these loans and the probability of repayment is based on the liquidation of the pledged collateral and enforcement of a personal guarantee, which Busey requires whenever appropriate on commercial loans. As a result, in the case of loans secured by accounts receivable, the availability of funds for the repayment of these loans may be substantially dependent on the ability of the borrower to collect amounts due from its customers, which could decline in the case of an economic recession. Collateral securing other loans may depreciate over time, may be difficult to appraise, and may fluctuate in value based on the success of the business. As a result of the larger average size of each commercial loan, as well as collateral that is generally less readily-marketable, losses incurred on a small number of commercial loans could have a material adverse impact on Busey’s financial condition and results of operations.
Our loan portfolio has a significant concentration of real estate loans, which involve risks specific to real estate values.
A significant portion of Busey’s loans are collateralized by real estate. Specifically, commercial real estate loans were $3.3 billion, or approximately 43.6% of our total loan portfolio, as of December 31, 2023. Of this amount, $914.5 million, or approximately 27.4%, was owner-occupied. The market value of real estate can fluctuate significantly in a short period of time as a result of market conditions in the area in which the real estate is located. Additionally, real estate lending typically involves higher loan principal amounts and the repayment of the loans generally is dependent, in large part, on sufficient income from the properties securing the loans to cover operating expenses and debt service. Economic events, including decreases in office occupancy following the COVID-19 pandemic, or governmental regulations outside of the control of the borrower or lender could negatively impact the future cash flow and market values of the affected properties. Collateral may have to be sold for less than the outstanding balance of the loan which would result in losses.
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 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
First Busey Corporation | 2023 — 40

Table of Contents Contents of Item 1A. Risk Factors
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.
Credit risk associated with concentration of securities in Busey’s investment portfolio may increase the potential for loss.
Busey’s investment portfolio consists, in part, of securities issued by government or government sponsored agencies and non-government entities. A downturn in the financial condition of the issuers, the performance of the underlying collateral, or the financial condition of the individual mortgagors with respect to the underlying securities could create results such as rating agency downgrades of the securities and default by issuers or individual mortgagors. Any of the foregoing factors could result in realized losses, which could adversely affect Busey’s financial condition and results of operations.
CAPITAL AND LIQUIDITY RISKS
Busey is required to maintain capital to meet regulatory requirements, and if it fails to maintain sufficient capital, whether as a result of losses, inability to raise additional capital, or otherwise, its financial condition, liquidity, and results of operations, as well as its ability to maintain regulatory compliance would be adversely affected.
Busey and Busey Bank must meet regulatory capital requirements and maintain sufficient liquidity. Busey’s ability to raise additional capital, when and if needed, will depend on conditions in the capital markets, economic conditions, and a number of other factors, including investor perceptions regarding the banking industry and market condition, and governmental activities, many of which are outside Busey’s control, and 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, we believe the pricing and other terms investors may require in such an offering may not be attractive to us.
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 and FDIC insurance costs, 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
First Busey Corporation | 2023 — 41

Table of Contents Contents of Item 1A. Risk Factors
Fintechs for retail deposits may impact our ability to raise funds through deposits and could have a negative effect on our 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.
External financial institution failures could impact the soundness of the Company.
Liquidity is a cornerstone of the Company, vital for sustaining day-to-day operations and strategic initiatives. Recent events, such as the bank failures in early 2023, underscore the critical nature of our ongoing efforts to manage liquidity risk effectively. As a core deposit-funded institution, our ability to raise funds through deposits is integral to our liquidity strategy. An inability to raise funds through deposits, borrowings, or other channels poses a substantial risk to our liquidity. Our primary funding sources, supplemented by channels like repurchase agreements and borrowing facilities, are crucial for sustaining day-to-day operations. External factors, such as disruptions in financial markets and increased competition for retail deposits, may challenge our access to funding sources. The bank failures serve as a stark reminder of potential challenges faced by financial institutions. As we navigate these complexities, any decline in funding and/or capital could adversely impact our ability to meet obligations, pay dividends, or address deposit withdrawals, with significant consequences for our liquidity, business, financial condition, and results of operations. Furthermore, the actions and commercial soundness of other financial institutions are pivotal for our routine funding and transactions. Market-wide liquidity problems triggered by defaults or rumors in the financial services industry could erode confidence and lead to losses or defaults.
COMPETITIVE AND STRATEGIC RISKS
If securities or industry analysts do not publish or cease publishing research reports about us, if they adversely change their recommendations regarding our stock, or if our operating results do not meet their expectations, the price of our stock could decline.
The trading market for our common stock will be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market, or our competitors. If there is limited or no securities or industry analyst coverage of us, the market price for our stock would be negatively impacted. Moreover, if any of the analysts who elect to cover us downgrade our common stock, provide more favorable relative recommendations about our competitors, or if our operating results or prospects do not meet their expectations, the market price of our common stock may decline. If one or more of these analysts ceases coverage of us or fails to publish reports on us regularly, demand for our stock could decrease, which could cause our stock price and trading volume to decline.
Busey faces strong competition from financial service companies and other companies that offer banking and wealth management services, which could harm its business.
Busey currently conducts its banking operations in central and suburban Chicago, Illinois; the St. Louis, Missouri, metropolitan area; central Indiana; and southwest Florida. In addition, the Company currently offers fiduciary and wealth management services, which account for a significant portion of its non-interest income. Many competitors offer the same, or a wider variety of, banking and wealth management services within Busey’s market areas. These competitors include national banks, regional banks, and other community banks. Busey also faces competition from many other types of financial institutions, including savings and loan institutions, finance companies, brokerage firms, insurance companies, credit unions, mortgage banks, digital banks and online lenders, and other financial intermediaries. In addition, a number of out-of-state financial intermediaries have opened production offices or otherwise solicit deposits in Busey’s market areas. Also, technology and other changes have lowered barriers to entry and made it possible for non-banks or financial technology companies, as well as other large technology corporations, to offer products and services traditionally provided by banks. For example, customers can maintain funds that would have historically been held as bank deposits in brokerage accounts or mutual funds, can apply for and receive credit, and can also complete
First Busey Corporation | 2023 — 42

Table of Contents Contents of Item 1A. Risk Factors
transactions such as paying bills and/or transferring funds without the assistance of banks. The process of eliminating banks as intermediaries, known as “disintermediation,” could result in the loss of fee income, as well as the loss of customer deposits and the related income generated from those deposits. Increased competition in Busey’s markets may result in reduced loans, deposits, and commissions and brokers’ fees, as well as reduced net interest margin and profitability. Ultimately, Busey may not be able to compete successfully against current and future competitors. If Busey is unable to attract and retain banking and wealth management customers, it may be unable to grow its loan and deposit portfolios or its wealth management commissions, which could adversely affect its business, results of operations, and financial condition.
While we do not offer products relating to digital assets, including cryptocurrencies, stablecoins and other similar assets, there has been a significant increase in digital asset adoption globally over the past several years. Certain characteristics of digital asset transactions, such as the speed with which such transactions can be conducted, the ability to transact without the involvement of regulated intermediaries, the ability to engage in transactions across multiple jurisdictions, and the anonymous nature of the transactions, are appealing to certain consumers notwithstanding the various risks posed by such transactions. Accordingly, digital asset service providers—which, at present are not subject to the same degree of scrutiny and oversight as banking organizations and other financial institutions—are becoming active competitors to more traditional financial institutions.
Rapid speed of disruptive innovations enabled by new and emerging technologies and/or other market forces may outpace Busey’s ability to compete.
The financial services industry is undergoing rapid technological changes with frequent introductions of new technology driven products and services. In addition to better serving clients, the effective use of technology increases efficiency and enables financial institutions to both reduce costs and service customers beyond the bank’s traditional branch footprint. The widespread adoption of new technologies, including mobile banking services, cryptocurrencies, and payment systems could require us in the future to make substantial expenditures to modify or adapt our existing products and services as we grow and develop new products to satisfy our customers’ expectations and comply with regulatory guidance. Our future success will depend in part upon our ability to address the needs of our clients by using technology to provide products and services that will satisfy client demands for convenience as well as to create additional efficiencies in our operations. Ultimately, there is no end for digital transformation and if we fall behind in our ability to be adaptive and innovative, attracting new customers and sustaining customer loyalty and retention may be increasingly difficult as a result of evolving customer preferences and/or demographic shifts in our existing customer base.
Our strategy of pursuing acquisitions exposes us to financial, execution, and operational risks that could negatively affect us.
To help us fulfill our strategic objectives and enhance our earnings, part of our strategy is to supplement organic growth by acquiring other financial institutions in our market areas and in nearby markets. The recently announced planned acquisition of M&M exemplifies this strategy. As our capital position and asset quality allow, we may continue to supplement organic growth through acquisitions, as we have in the past. There are risks associated with acquisition strategies, including the following:
•We are exposed to potential asset and credit quality risks and unknown or contingent liabilities of the banks or businesses we acquire. If these issues or liabilities exceed our estimates, our earnings and financial condition may be materially and adversely affected.
•Prices at which acquisitions can be made fluctuate with market conditions. We have experienced times during which acquisitions could not be made in specific markets at prices our management considered acceptable, and we expect that we will experience this condition in the future in one or more markets.
•The acquisition of other entities generally requires integration of systems, procedures, and
First Busey Corporation | 2023 — 43

Table of Contents Contents of Item 1A. Risk Factors
personnel of the acquired entity in order to make the transaction economically feasible. This integration process is complicated and time consuming and can also be disruptive to the customers of the acquired business. If the integration process is not conducted successfully and with minimal effect on the acquired business and its customers, we may not realize the anticipated economic benefits of particular acquisitions within the expected time frame, and we may lose customers or employees of the acquired business. Furthermore, the integration of personnel can be challenging and the likelihood of turnover of personnel from acquired institutions presents potential risks to both operational efficiency as well as customer retention. Busey may also experience greater than anticipated customer losses even if the integration process is successful.
•We are subject to due diligence expenses which may not result in an acquisition.
•To finance an acquisition, we may borrow funds, thereby increasing our leverage and diminishing our liquidity, or issue capital stock to the sellers in an acquisition or to third-parties to raise capital, which could dilute the interests of our existing stockholders.
•The time period in which anticipated benefits of a merger are fully realized may take longer than anticipated, or we may be unsuccessful in realizing the anticipated benefits from mergers and future acquisitions.
New lines of business or new products and services may subject us to additional risks.
From time to time, we may seek to implement new lines of business or offer new products, services, or delivery channels within existing lines of business in our current markets or new markets. There are substantial risks and uncertainties associated with these efforts, particularly in instances where the markets are either highly competitive or, conversely, not fully developed. In developing and marketing new lines of business and/or new products and services, we may invest significant time and resources. Initial timetables for the introduction and development of new lines of business and/or new products or services may not be achieved, and price and profitability targets may not prove feasible, which could in turn have a material negative effect on our operating results.
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 difficult, 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 its 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 goodwill or other intangible assets impairment charges, 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.
Busey is subject to changes in accounting principles, policies, or guidelines.
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 the Company’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,
First Busey Corporation | 2023 — 44

Table of Contents Contents of Item 1A. Risk Factors
social, and governance related disclosures, could require us 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 our 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 are beyond the Company’s control. Changes in tax laws could affect Busey’s earnings as well as its customers’ financial positions, or both.
Deferred tax assets are designed to reduce subsequent period’s income tax expense and arise, in part, as a result of net loss carry-overs, and other book accounting to tax accounting differences including expected credit losses, stock-based compensation, and deferred compensation. Such items are recorded as assets when it is anticipated the tax consequences will be recorded 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 us. 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.
Further, Busey’s investments in certain 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. Busey’s investments in these projects are designed to generate a return primarily through the realization of federal and state income tax credits, and other tax benefits, over specified time 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 to be met at the project level, will fail to meet certain government compliance requirements and will not be realized. The possible inability to realize these tax credit and other tax benefits could have a negative impact on Busey’s financial results. The ultimate realization of the tax credits and other tax benefits depends upon having sufficient taxable income and on many factors outside of the Company’s control, including changes in the applicable tax code and the ability of the projects to be completed.
OPERATIONAL RISKS
Busey’s framework for managing risks may not be effective in mitigating risk and loss.
Busey’s risk management framework seeks to mitigate risk and loss. It has established processes and procedures intended to identify, measure, monitor, report, and analyze the types of risk to which it is subject, compliance risk and reputational risk, among others. However, as with any risk management framework, there are inherent limitations. Risks may exist, or emerge in the future, that have not been appropriately identified or anticipated. As it continues to grow, Busey’s ability to successfully identify and manage the risks it faces is an important factor that can significantly impact results. If its risk management framework is not commensurate with its risk profile, Busey could suffer unexpected losses and could be materially adversely affected.
First Busey Corporation | 2023 — 45

Table of Contents Contents of Item 1A. Risk Factors
Busey relies on the integrity of its operating systems and employees, and those of third-parties, and certain failures of such systems or error by employees or customers could materially and adversely affect Busey’s operations.
Communications and information systems are essential to conduct Busey’s business, as it uses such systems to manage customer transactions and relationships; the general ledger; and deposits, loans, and investments. However, the computer systems and network infrastructure Busey uses could be vulnerable to unforeseen problems as operations are dependent upon the protection of computer equipment against damage from physical theft, fire, power loss, telecommunications failure, or a similar catastrophic event, as well as from security events.
In addition, Busey outsources certain processing functions to third-party providers introducing additional layers of risk when these providers, in turn, outsource to fourth or fifth parties. This cascading outsourcing structure can heighten the complexity and potential challenges in communication, coordination, and risk management. If downstream providers encounter difficulties, or if Busey faces challenges in communicating with them, it may impact the ability to adequately process and account for customer transactions, adversely affecting business operations. Moreover, downstream providers could introduce specific risks related to compliance. Involvement of downstream parties in regions subject to sanctions or dealing with entities on prohibited lists poses an additional layer of regulatory risk.
Risks associated with multi-layered outsourcing arrangements include compliance concerns, potential disruptions, system or processing failures, and increased difficulty in overseeing and controlling actions of distant parties. While Busey implements due diligence procedures in reviewing and vetting its third-parties, the indirect risks arising from subsequent outsourcing levels are inherently more challenging to control or cannot be controlled.
Although Busey has established procedures to prevent or mitigate the effects of potential problems, technology-related disruptions, failures, and cybersecurity risks remain constant threats. Involvement of downstream parties further amplifies these risks, as Busey cannot guarantee the success of measures to prevent security breaches and disruptions. Any failure, interruption, or breach in the security of computer systems and network infrastructure, including those of downstream parties, could have a material adverse effect on Busey’s financial condition and results of operations.
Similarly, Busey is reliant upon its employees. Such dependencies create risks for potential losses resulting from employee errors, breakdowns in process or control, failures to properly execute change management, negligence, or a number of other factors outside Busey’s control. Busey maintains a system of internal controls and insurance coverage to mitigate operational risks, including data processing system failures and errors, customer or employee fraud, and other disruptions which might impact its business. Further, Busey’s Internal Audit department routinely reviews operations and high-risk areas for error, deficient controls, and failure to adhere to policy.
Potential legal actions, fines, and civil money penalties could arise as results of an operational deficiency or as a result of noncompliance with applicable regulatory standards, adverse business decisions or their implementation, and customer attrition due to potential negative publicity.
A breach in the security of Busey’s systems could disrupt its businesses, result in the disclosure of confidential information, damage its reputation, and create significant financial and legal exposure for Busey.
Although Busey devotes significant resources to maintain and regularly upgrade systems and processes designed to protect the security of its computer systems, software, networks, and other technology assets, these measures do not provide absolute security for the Company’s websites or other systems, some of which have been targeted with sophisticated intended to obtain unauthorized access to confidential information, destroy data, disable or degrade service, or sabotage systems, often through the introduction of computer viruses or malware, cyber-attacks, and other means. In addition, cyber attackers have persistently employed sophisticated campaigns to leverage individuals' fears and uncertainties. They capitalize on the increased
First Busey Corporation | 2023 — 46

Table of Contents Contents of Item 1A. Risk Factors
volume of transactions occurring on digital channels, employing social engineering techniques to manipulate human psychology and perpetuate security breaches. Implementation of remote working arrangements that use virtual private networks, virtual conferencing services, and telecommunication technologies can increase insider risk, cybersecurity vulnerabilities, and other operational exposures. Industry trends in ransomware, phishing, and other intrusion methods have increased significantly and will continue to pose increased risk.
Threats to security also exist in the processing of customer information through various other third-parties, their personnel, and their use of subcontractors. Advances in computer capabilities, new discoveries in the field of cryptography, or other developments could result in a compromise or breach of the algorithms Busey and its third-party service providers use to encrypt and protect customer transaction data. Such cyber incidents may go undetected for a period of time. An inability by our third-party providers, and their third-party providers, to anticipate, detect, or adequately mitigate, breaches of security, known as “supply chain risk,” could result in a number of negative events, including losses to us or our clients, loss of business or clients, damage to our reputation, the incurrence of additional expenses, additional regulatory scrutiny or penalties, or exposure to civil litigation and possible financial liability, any of which could have a material adverse effect on our business, financial condition, results of operations, and growth prospects.
Busey also faces risks related to cyber-attacks and other security breaches in connection with credit card, debit card, and other payment-related transactions that typically involve the transmission of sensitive information regarding Busey’s customers through various third-parties, including merchant acquiring banks, payment processors, payment card networks, and processors. Cyber-attacks or other breaches, whether affecting Busey or others, could intensify consumer concern and regulatory focus and result in breach and fraud-related losses as well as increased costs, all of which could have a material adverse effect on Busey’s business.
Penetration or circumvention of Busey’s security systems could result in serious negative consequences for the Company, including significant disruption of Busey’s operations, misappropriation of Busey’s confidential information or that of its customers or employees, or damage to Busey’s computers or systems and those of its customers and counterparties. Such events could result in violations of applicable privacy and other laws, financial loss to Busey or its customers, loss of confidence in Busey’s security measures, customer dissatisfaction, significant litigation exposure, and harm to Busey’s reputation, all of which would adversely affect the Company.
These risks have increased for all financial institutions globally as new technologies, the use of the Internet and telecommunications technologies, including mobile devices, to conduct financial and other business transactions, and the sophistication and activities of malicious individuals and organizations have increased substantially. Despite Busey’s significant investment in security resources and its continued efforts to prevent or limit the effects of potential threats, it is possible that Busey may not be able to anticipate or implement effective preventative measures against all security incidents.
Customer or employee misconduct or fraud may affect operations, result in significant financial loss, and have an adverse impact on Busey’s reputation.
Misconduct by employees and customers could include hiding unauthorized activities, conducting improper or unauthorized activities, or improper use of confidential information. Customer or other outsiders may also attempt to perpetuate fraud or scams in the form of identity theft, money laundering, fraudulent or altered deposits, or use of counterfeit instruments, as a few examples. Busey also faces fraud risk associated with the origination of loans, including the intentional misstatement of information in property appraisals or other underwriting documentation provided to it by customers or by third-parties. Customers may expose Busey to certain fraud risks associated with the compromise of their computing systems or accounts, as well.

Table of Contents Contents of Item 1A. Risk Factors
Both the number and sophistication level of attempted fraudulent transactions are increasing. Should our internal controls fail to prevent or detect an occurrence of fraud, or if any resulting loss is not insured or exceeds applicable insurance limits, it could have a material adverse effect on Busey’s business, results of operations, and financial condition.
Busey’s ability to attract and retain key personnel may affect future growth and earnings.
Busey's leadership landscape recently underwent changes as Busey and Robin N. Elliott, the President and Chief Executive Officer of Busey Bank, who also served as Chairman of the Board and Chief Executive Officer of FirsTech, mutually agreed upon the decision to part ways. In connection with this transition, Van A. Dukeman, the Chairman, President, and Chief Executive Officer of First Busey Corporation has taken on the additional role of President and Chief Executive Officer of Busey Bank. Busey’s ability to attract and retain management experienced in banking and financial services, including its current executive officers, management teams, lending and retail banking officers, and administrative staff of its subsidiaries, is crucial for the successful implementation of its strategy. Additionally, Busey's ability to retain key personnel at acquired financial institutions is vital for its growth strategy through mergers and acquisitions. Equally critical is Busey’s commitment to attracting and retaining diverse and qualified staff with the appropriate level of experience and knowledge about its market areas, essential for implementing its community-based operating strategy. The unexpected loss of services of key personnel or the inability to recruit and retain qualified personnel in the future could have an adverse effect on Busey’s business, financial condition, and results of operation.
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, a failure or perceived failure to deliver appropriate standards of service and quality or to treat customers fairly, 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 results of such actual or alleged misconduct could include customer dissatisfaction, inability to attract potential acquisition prospects, litigation, and heightened regulatory scrutiny, all of which could lead to lost revenue, higher operating costs, and harm to Busey’s reputation. No assurance can be made, despite the cost or efforts made by the Company to address the issues arising from reputational harm, that results could not adversely affect Busey’s business, financial condition, and results of operations.
Emerging risks associated with Generative Artificial Intelligence and other Large Language Models are dynamic and evolving rapidly as the technology advances and regulatory frameworks develop.
While our current operational framework excludes the use of GAI in our internal processes, the usage of such technologies introduces a spectrum of risks across various dimensions:
•Fraud and Security – Advanced social engineering capabilities for phishing and vishing attacks, as well as the ability to generate impersonation attacks using so called “deep fakes” leading to impacts including, but not limited to, unauthorized access, fraudulent transactions, and data breach.
•Intellectual Property and Copyright Concerns – Risks stemming from unclear legal disputes and potential financial liabilities due to the unauthorized use of copyrighted materials leading to legal challenges.
•Potential Opacity and Bias in Models – Challenges related to the interpretability of models and potential biases, presenting risks of model misinterpretation and unintended consequences.
First Busey Corporation | 2023 — 48

Table of Contents Contents of Item 1A. Risk Factors
•Data Privacy – Unauthorized use of company or customer data in the training of GAI models.
•Compliance Challenges – The potential inability to quickly adapt to, or the high costs associated with adapting to, regulatory changes, leading to compliance gaps and associated penalties.
Moreover, an additional concern with GAI pertains to the utilization of voice-enabled AI for communicating promotional messages to our customer base. As we proactively assess and address these emerging risks, our commitment to robust risk management remains integral to sustaining operational resilience.
ITEM 1B. UNRESOLVED STAFF COMMENTS
None.
ITEM 1C. CYBERSECURITY
Busey relies extensively on various information systems and other electronic resources to operate our business. In addition, nearly all of our customers, service providers and other business partners on whom we depend, including the providers of our online banking, mobile banking, and accounting systems, use their own information systems and electronic resources. Any of these systems can be compromised, including through the employees, customers, and other individuals who are authorized to use them, and bad actors who use a sophisticated and constantly evolving set of software, tools, and strategies to do so. Moreover, the nature of our business, as a financial services provider, and our relative size, make us and our business partners high-value targets for these bad actors to pursue. For additional information see “Item 1A. Risk Factors—Operational Risks.”
Accordingly, we have long devoted significant resources to assessing, identifying and managing risks associated with cybersecurity threats, including:
•an internal cybersecurity team that is responsible for conducting regular assessments of our information systems, existing controls, vulnerabilities and potential improvements;
•continuous monitoring tools that can detect and help respond to cybersecurity threats in real-time;
•performing due diligence with respect to our third-party service providers, including their cybersecurity practices, and requiring contractual commitments from our service providers to take certain cybersecurity measures;
•third-party cybersecurity consultants, who conduct periodic penetration testing, vulnerability assessments and other procedures to identify potential weaknesses in our systems and processes; and
•periodic cybersecurity training for our workforce.
This information security program is a key part of our overall risk management system, which is administered by our Chief Risk Officer. The program includes administrative, technical and physical safeguards to help ensure the security and confidentiality of customer records and information. These security and privacy policies and procedures are in effect across all of our businesses and geographic locations.
We face a number of cybersecurity risks in connection with our business. From time-to-time, we have identified cybersecurity threats and cybersecurity incidents that require us to make changes to our processes and to implement additional safeguards. While none of these identified threats or incidents have materially affected us, it is possible that threats and incidents we identify in the future could have a material adverse effect on our business strategy, results of operations, and financial condition.
First Busey Corporation | 2023 — 49

Table of Contents
Our management team is responsible for the day-to-day management of risks we face, including our Chief Information Security Officer (“CISO”). Our CISO has been in the role since September 2020, and has 15 years of experience across external and internal audit, technology risk management, and cybersecurity spanning various industries primarily within the financial services sector, but also including healthcare, technology, consumer products, and manufacturing for both regional and multinational corporations.
In addition, our 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, our board of directors and Risk Committee, with support from Busey’s cybersecurity advisors, are responsible for ensuring that the risk management processes designed and implemented by management are adequate and functioning as designed. To carry out those duties, both our board of directors and the Risk Committee receive quarterly reports from our management team regarding cybersecurity risks, and Busey’s efforts to prevent, detect, mitigate, and remediate any cybersecurity incidents.

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 the Company—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.

Table of Contents
As of February 22, 2024, First Busey Corporation had 55,247,094 shares of common stock outstanding held by 1,804 holders of record. Additionally, there were an estimated 10,830 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 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

SCOPE OF DISCUSSION
The following is management’s discussion and analysis of the financial condition as of December 31, 2023, and 2022, and the results of operations for the years ended December 31, 2023, 2022, and 2021, 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 the financial condition and results of operation for 2023 as compared to 2022 can be found below. Comparison of 2022 to 2021 can be found in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” of our 2022 Annual Report.
BUSEY’S CONSERVATIVE BANKING STRATEGY
Busey’s financial strength is built on a long-term conservative operating approach. The quality of our core deposit franchise is a critical value driver of our institution. Since March 31, 2023, our deposit base has grown by $490.0 million, allowing us to reduce our higher cost FHLB borrowings to zero. Busey remains substantially core deposit 1 funded, with robust liquidity and significant market share in the communities we serve. As of December 31, 2023, our loan to deposit ratio was 74.4% and core deposits 1 represented 96.2% of total deposits. Furthermore, we have sufficient on- and off-balance sheet liquidity to manage deposit fluctuations and the liquidity needs of our customers.
Our credit performance reflects our highly diversified, conservatively underwritten loan portfolio, which has been originated predominantly to established customers with tenured relationships with our Company. Our approach to lending and our underwriting standards are designed to emphasize relationship banking rather than transactional banking. In addition, as a matter of both policy and practice, we limit 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 our capital base. We strive 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, 2023, our leverage ratio of Tier 1 capital to average assets was 10.1%, our common equity Tier 1 capital to risk weighted assets ratio was 13.1%, and our total capital to risk weighted assets ratio was 17.4%.
CRITICAL ACCOUNTING ESTIMATES
Busey has established various accounting policies that govern the application of GAAP in the preparation of its Consolidated Financial Statements. Significant accounting policies are described in “Note 1. Significant Accounting Policies” in the Notes to the Consolidated Financial Statements.
Critical accounting estimates are those that are critical to the portrayal and understanding of Busey’s financial condition and results of operations and require management to make assumptions that are difficult, 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 our critical accounting estimates. The following policies could be deemed critical:

First Busey Corporation | 2023 — 54

Table of Contents Contents of Item 7. MD&A
Fair Value of Debt Securities Available for Sale
Fair values of debt securities available for sale are measurements from an independent pricing service and are based on observable data that may include dealer quotes, market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information, and the security’s terms and conditions, among other things. Different fair value estimates could result from the use of different judgments and estimates to determine the fair values of securities.
Realized securities gains or losses are reported in the Consolidated Statements of Income. The cost of securities sold is based on the specific identification method.
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, we must first determine if we intend to sell the security or if it is more likely than not that we 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, we will write down the amortized cost basis of the security to its fair value. This is achieved by writing off any previously recorded allowance related to the debt security, if applicable, and recognizing any incremental impairment through earnings. If we do not intend to sell the security, nor believe it more likely than not that we will be required to sell the security before the fair value recovers to the amortized cost basis, we 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.
We consider 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.
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.”
First Busey Corporation | 2023 — 55

Table of Contents Contents of Item 7. MD&A
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 in 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. Determining the fair value often involves estimates based on third-party valuations, such as appraisals, or internal valuations based on discounted cash flow analyses or other valuation techniques. Goodwill is not amortized, instead, we assess the potential for impairment on an annual basis or more frequently if events and circumstances indicate that goodwill might be impaired.
Income Taxes
Busey estimates income tax expense based on amounts expected to be owed to federal and state tax jurisdictions. Estimated income tax expense is reported in the Consolidated Statements of Income. Accrued and deferred taxes, as reported in other assets or other liabilities in the Consolidated Balance Sheets, represent the net estimated amount due to or to be received from taxing jurisdictions either currently or in the future. Management judgment is involved in estimating accrued and deferred taxes, as it may be necessary to evaluate the risks and merits of the tax treatment of transactions, filing positions, and taxable income calculations after considering tax-related statutes, regulations, and other relevant factors. Because of the complexity of tax laws and interpretations, interpretation is subject to judgment.
Allowance for Credit Losses
Busey calculates the ACL at each reporting date. We recognize an allowance for the lifetime expected credit losses for the amount we do 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, we may conclude a loan should be evaluated on an individual basis based on the 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 by management. Because of the nature of the judgments and assumptions made by management, actual results may differ from these judgments and assumptions.

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 our 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. Average information is provided on a daily average basis (dollars in thousands):

The FOMC raised rates by a total of 100 basis points during 2023, and by a total of 525 basis points since the onset of the current FOMC tightening cycle that began in the first quarter of 2022. Rising rates initially have a positive impact on net interest margin, as assets, in particular commercial loans, reprice more quickly and to a greater extent than liabilities. As deposit and funding costs increase in response to the tightening rate cycle, and we experience deposit migration into higher cost offerings and funding alternatives, some of the net interest margin expansion is reversed.
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 $122.4 million for the year ended December 31, 2023, a decrease of 3.5% when compared with $126.8 million for the year ended December 31, 2022. The year-over-year decrease in non-interest income is substantially attributable to Durbin Amendment impacts as described in further detail below. Total noninterest income represented 27.7% of total revenue 2 in 2023, compared to 28.2% in 2022.
Combined, revenues from wealth management fees and payment technology solutions represented 64.1% and 59.5% of Busey’s noninterest income for the years ended December 31, 2023, and December 31, 2022, respectively, providing a complement to spread-based revenue from traditional banking activities. On a combined basis, revenue from these two critical operating areas was $78.5 million for the year ended December 31, 2023, a 4.1% increase from $75.4 million for the year ended December 31, 2022.
Wealth management fees increased by 3.5% to $57.3 million in 2023, compared to $55.4 million in 2022. Busey’s Wealth Management division had $12.1 billion in assets under care as of December 31, 2023, compared to $11.1 billion as of December 31, 2022. Our 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 our payment processing company, FirsTech. Payment technology solutions revenue increased by 5.6% to $21.2 million in 2023, compared to $20.1 million in 2022. Results for 2023 marked a new record high reported annual revenue for FirsTech.

Fees for customer services decreased by 12.3% to $29.0 million in 2023, compared to $33.1 million in 2022. Beginning on July 1, 2022, we became subject to the Durbin Amendment, which requires the Federal Reserve to establish a maximum permissible interchange fee for many types of debit transactions. Reduced fee income is primarily attributable to the impact of the Durbin Amendment for all of 2023 versus only half of 2022, as well to modifications implemented to overdraft and non-sufficient funds fee structures.
Mortgage revenue was $1.1 million in 2023, compared to $1.9 million in 2022. Decreases primarily resulted from declines in mortgage origination and sold-loan mortgage volume. General economic conditions and interest rate volatility may impact future fee income.
Income on bank owned life insurance increased by 28.3% to $4.7 million in 2023, compared to $3.7 million in 2022, resulting from a $0.8 million increase in earnings on death proceeds and a $0.2 million increase in the cash surrender value of the insurance policies.
Other income decreased by 24.1% to $11.2 million in 2023, compared to $14.8 million in 2022. Primary contributors to other income include swap origination fees, gains on commercial loans sales, and changes in venture capital investment valuations.

Total noninterest expense increased to $285.5 million for the year ended December 31, 2023, compared to $283.9 million for the year ended December 31, 2022, representing a modest year-over-year increase of 0.6%. Non-operating acquisition and other restructuring expenses decreased to $4.3 million in 2023, compared to $4.5 million in 2022. We have effectively managed our noninterest expense during a time of decades-high inflation, and have been purposeful in our efforts to rationalize our expense base given our economic outlook and our view on the future of banking.
Salaries, wages, and employee benefits increased to $162.6 million in 2023, compared to $159.0 million in 2022. Our total associate base consisted of 1,479 full-time equivalents as of December 31, 2023, compared to 1,497 at December 31, 2022. Non-operating costs contributed $0.8 million of the increase in salaries, wages, and employee benefits. Current trends continue to reflect a competitive labor market, maintaining pressure on costs related to attracting and maintaining our skilled workforce.
Data processing expense increased to $23.7 million in 2023, compared to $21.6 million in 2022. 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 decreased to $25.0 million in 2023, compared to $26.8 million in 2022. Decreases were primarily attributable to declines in depreciation expense and real estate taxes.
Professional fees increased to $7.1 million in 2023, compared to $6.1 million in 2022. The increase was primarily attributable to higher expenses for audit and accounting fees and payroll services.
Amortization of intangible assets decreased to $10.4 million in 2023, compared to $11.6 million in 2022, due to the continued use of an accelerated amortization methodology.
Interchange expense increased to $6.9 million in 2023, compared to $6.3 million in 2022. Fluctuations in interchange expense were primarily the result of increased payment and volume activity at FirsTech.
FDIC insurance expense increased to $5.7 million in 2023, compared to $4.1 million in 2022. Increases were the result of an FDIC final rule to increase the initial base deposit insurance assessment rate applicable to all depository institutions by two basis points beginning in 2023.
Other expense decreased to $44.2 million in 2023, compared to $48.3 million in 2022. Primary contributors to other expense include business development, collection and preservation, OREO, fixed asset impairments, provision for unfunded commitments, and NMTC impairments. Decreases were across multiple expense categories as a result of expense discipline.
Efficiency Ratio 3
The efficiency ratio 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. Our efficiency ratio was 61.7% for the year ended December 31, 2023, compared to 59.9% for the year ended December 31, 2022. Operating costs have been influenced by acquisition expenses and other restructuring costs, and the adjusted efficiency ratio 3 was 60.7% for the year ended December 31, 2023, compared to 58.9% for the year ended December 31, 2022.
Income Taxes
Effective income tax rates, calculated by dividing income taxes by income before taxes, were 20.4%, 20.7%, and 21.3% for the years ended December 31, 2023, 2022, and 2021, respectively. Busey's effective tax rates were 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, and investments in various tax credits. We continue to monitor evolving federal and state tax legislation and its potential impact on operations on an ongoing basis. As of December 31, 2023, we were not under income tax examination by any income tax authority.

Busey executed a two-part balance sheet repositioning strategy
During the fourth quarter of 2023, Busey sold all 16,878 shares of Visa Class B common stock it previously held (the “Visa Sale”) resulting in a pre-tax gain of approximately $5.5 million, and also executed a balance sheet repositioning of its available-for-sale securities portfolio (the “Repositioning”). Busey sold securities with a carrying value of approximately $110 million yielding 1.56%, resulting in a pre-tax loss of $5.3 million. Proceeds were deposited into an interest-bearing account at the Federal Reserve yielding 5.40%, a higher-yielding lower risk-weighted asset.
The increased net interest spread as a result of the Visa Sale and Repositioning is expected to increase net interest income by approximately $4.3 million on an annualized basis and improve Busey’s net interest margin run rate by 4 basis points. In addition, execution of these transactions further bolsters Busey’s liquidity position and balance sheet flexibility, while also strengthening its capital position. Busey anticipates reinvesting the proceeds into higher yielding organic growth opportunities over time.
The combined impact of the gain generated from the Visa Sale and the loss generated from the Repositioning will have an immediate positive impact on consolidated stockholders’ equity and book value per share. Risk-based regulatory capital ratios will increase modestly as a result of the Repositioning proceeds rotating into lower risk-weighted assets. Busey expects the above transactions to be accretive to capital and earnings per share in future periods.

Investment Securities
The primary purposes of our 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.
We consider many factors in determining the composition of our 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, 2023, we did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of the Company’s stockholders’ equity.
Pledged securities totaled $837.4 million, or 28.3% of total debt securities, as of December 31, 2023, and $746.7 million, or 22.1% of total debt securities, as of December 31, 2022.

Portfolio Loans
We believe that making sound and profitable loans is a necessary and desirable means of employing funds available for investment. Busey maintains lending policies and procedures designed to focus lending efforts on the types, locations, and duration of loans most appropriate for its business model and markets. While not specifically limited, we attempt to focus our lending on short to intermediate-term (0-10 years) loans in geographic areas within 125 miles of our lending offices. Loans originated outside of these areas are generally to existing customers of Busey Bank. We attempt 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. Our 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.
As a matter of policy and practice, we limit the level of concentration exposure in any particular loan segment with the goal of maintaining a well-diversified loan portfolio.
At no time is a borrower’s total borrowing relationship permitted to exceed Busey Bank’s regulatory lending limit. We generally limit 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 our loan policy on a periodic basis. In addition, the loan review department reviews risk assessments made by our 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 activities can be summarized into two primary categories: commercial and retail. Within these primary categories, loans are further classified into five primary lending areas. The commercial category includes commercial loans, commercial real estate loans, and real estate construction loans. The retail category includes retail real estate loans and retail other loans.
Commercial Loans
Commercial loans typically comprise working capital loans or business expansion loans, including loans for asset purchases and other business loans. Commercial loans will generally be guaranteed, in full or a material percentage, by the primary owners of the business. 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 commercial loan types.

Commercial Real Estate Loans
The commercial environment, along with the academic presence in some of our markets, provides for the majority of our commercial lending opportunities to be commercial real estate related, including multi-unit housing. As the majority of our loan portfolio is within the commercial real estate class, our goal is to maintain a high quality, geographically diverse portfolio of commercial real estate loans. Commercial real estate loans are subject to underwriting standards and guidelines similar to commercial loans. Commercial real estate 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, commercial real estate 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 we closely monitor.
Real Estate Construction Loans
Real estate construction loans are primarily commercial in nature. Loan proceeds are monitored by the Company and advanced for the improvement of real estate in which we hold 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 2023, Busey retained a larger percentage of originated retail real estate loans in our portfolio, electing to sell a smaller percentage to secondary market purchasers. As retail real estate loan underwriting is subject to specific regulations, we typically underwrite our 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.

Allowance and Provision for Credit Losses
The ACL is a significant estimate in our Consolidated Balance Sheets, affecting both earnings and capital. The methodology adopted influences, and is influenced by, Busey Bank’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. All 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):

| Years Ended December 31,
| 2023 |  | 2022 |  | 2021
Provision for credit losses | $ | 2,399 |  |  | $ | 4,623 |  |  | $ | (15,101) |

The provision release in 2021 reflected improvements in macroeconomic conditions and asset quality, following a build-up of the ACL in the prior year attributable to the adoption of CECL in combination with the economic impacts of the COVID-19 pandemic.

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, 2023, Busey management believed the level of the allowance to be appropriate based upon the information available. However, additional losses may be identified in our 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 our interest in the underlying collateral less estimated costs to sell. Our loan portfolio is collateralized primarily by real estate.

Non-performing assets declined by 52.13% to $7.9 million as of December 31, 2023, compared to $16.6 million as of December 31, 2022. Non-performing assets represented 0.06% of total assets as of December 31, 2023, compared to 0.13% as of December 31, 2022. Our allowance for credit losses provided 1,155.27% coverage of our non-performing assets at December 31, 2023, up from 552.19% at December 31, 2022.

Classified assets, which includes non-performing assets and substandard loans, decreased to $72.3 million as of December 31, 2023, compared to $107.1 million as of December 31, 2022. Classified assets represented 4.97% of Busey Bank’s Tier 1 capital and ACL at December 31, 2023, down from 7.66% at December 31, 2022.
Net charge-offs totaled $2.3 million in 2023, representing 0.03% of average loans, compared with net charge-offs of $0.9 million in 2022, representing 0.01% of average loans.
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, we would expect the credit quality of our 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, restructured, 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 $64.3 million at December 31, 2023, compared to $89.2 million at December 31, 2022. Management continues to monitor these credits and anticipates that restructurings, guarantees, additional collateral, or other planned actions will result in full repayment of the debts. As of December 31, 2023, 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.
COVID-19 Modifications
To alleviate some of the financial hardships faced as a result of COVID-19, Busey offered a Financial Relief Program to qualifying customers. The program included options for short-term loan payment deferrals and certain fee waivers. We had no commercial or retail loans remaining in the program as of December 31, 2023. In comparison, we had eight payment deferred commercial loans totaling $20.6 million that were on interest-only payment terms, and one payment deferred retail loan totaling $0.1 million as of December 31, 2022.

Total deposits increased by 2.2% to $10.3 billion as of December 31, 2023, compared to $10.1 billion as of December 31, 2022. Growth in our deposit base coupled with cash flows from our securities portfolio allows us to fund loan growth while limiting our reliance on higher cost wholesale funding alternatives. We focus on deepening our relationship with customers to maintain and protect our strong core deposit 4 franchise, allowing us to reduce our reliance on wholesale funding. As of December 31, 2023, our average customer tenure was 16.5 years for retail customers and 12.4 years for commercial customers. Core deposits 4 include non-brokered transaction accounts, money market deposit accounts, and time deposits of $250,000 or less. Core deposits 4 represented 96.2% of total deposits as of December 31, 2023, compared to 98.8% as of December 31, 2022.
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 $3.8 billion at December 31, 2023. The portion of our deposit base that was uninsured and not otherwise collateralized was estimated to be $2.8 billion at December 31, 2023, which represented 27% of total deposits. Of that amount, $350.1 million represented time deposits. The following table presents estimates of the uninsured portion of time deposits by maturity date (dollars in thousands):

Borrowings
Term Loan
On May 28, 2021, Busey entered into a Second Amended and Restated Credit Agreement, pursuant to which we have 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 loans now have an annual interest rate of 1.80% plus the one-month forward-looking term rate based on SOFR. On April 30, 2023, the agreement was further amended to extend the term for the revolving line of credit to April 30, 2024.
Proceeds of the Term Loan were used to fund a part of the cash portion of the merger consideration related to the acquisition of CAC in the second quarter of 2021, and for general corporate purposes. The total outstanding balance on the Term Loan was $30.0 million as of December 31, 2023, of which $12.0 million was short-term and $18.0 million was long-term. Quarterly payments on the Term Loan reduce the outstanding principal balance by $3.0 million each quarter.
As of December 31, 2023, there was no balance outstanding on the revolving credit facility. The revolving credit facility incurs a non-usage fee based on any undrawn amounts.
Securities Sold Under Agreements to Repurchase and Short-term Borrowings
Securities sold under agreements to repurchase, which are classified as secured borrowings, generally mature daily. 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.

Senior and Subordinated Notes
On May 25, 2017, we issued $40.0 million of 3.75% senior notes that matured and were redeemed on May 25, 2022. Additionally, on May 25, 2017, we issued $60.0 million of fixed-to-floating rate subordinated notes that were scheduled to mature on May 25, 2027, with an optional redemption in whole or in part on any interest payment date on or after May 25, 2022. We redeemed all $60.0 million of the outstanding fixed-to-floating rate subordinated notes during the third quarter of 2022. At the time of redemption, the redeemed subordinated notes carried interest at a floating rate of 3-month LIBOR plus 2.919%.
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 | 2023 — 84

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 will accrue 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 basis points 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.
Unamortized debt issuance costs related to subordinated notes are presented in the following table (dollars in thousands):

Total unamortized debt issuance costs | $ | 2,118 |  |  | $ | 2,962 |

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, we 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. In connection with the Pulaski acquisition in 2016, we acquired similar statutory trusts previously maintained by Pulaski and the fair value adjustment is being accreted over their weighted average remaining life, with a balance remaining to be accreted of $2.6 million at December 31, 2023. We had $72.0 million and $71.8 million of junior subordinated debt owed to unconsolidated trusts at December 31, 2023, and 2022, respectively.
Liquidity
Liquidity management is the process by which we ensure that adequate liquid funds are available to meet the present and future cash flow obligations arising in the daily operations of our 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. Our most liquid assets are cash and due from banks, interest-bearing bank deposits, and federal funds sold. Balances of these assets are dependent on our operating, investing, lending, and financing activities during any given period.

Busey’s primary sources of funds consist of deposits, investment maturities and sales, loan principal repayments, and capital funds. Additional liquidity is provided by the ability to borrow from the FHLB, the Federal Reserve Bank, and our revolving credit facility, as summarized in the table below (dollars in thousands):

Further, the company could utilize brokered deposits as additional sources of liquidity, as needed.
As of December 31, 2023, management believed that adequate liquidity existed to meet all projected cash flow obligations. We seek 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.
Our ability to pay cash dividends to our stockholders and to service our debt is dependent on the receipt of cash dividends from our subsidiaries. Busey Bank paid dividends to First Busey Corporation totaling $90.0 million and $95.0 million for the years ended December 31, 2023, and 2022, respectively.

Cash Flows
Busey’s cash flows consist of operating activities, investing activities, and financing activities.
Net cash flows provided by operating activities totaled $173.4 million in 2023, compared to $165.9 million provided by operating activities in 2022. Significant operating activities affecting cash flows include net income, depreciation and amortization, 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 $551.0 million in 2023, compared to $291.0 million used in investing activities in 2022. Significant investing activities are those associated with managing Busey’s investment and loan portfolios.
Net cash used in financing activities totaled $232.0 million in 2023, compared to $483.9 million used in financing activities in 2022. Significant financing activities affecting cash flows include deposit and other borrowings, as well as cash dividends paid.
For additional detail, see the Consolidated Statemen ts of Cash F lo ws.
Capital Resources
Our 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, 2023.

| Minimum Capital Requirements with Capital Buffer |  | As of December 31, 2023
|  | First Busey |  | Busey Bank
Common Equity Tier 1 Capital to Risk Weighted Assets | 7.00 | % |  | 13.09 | % |  | 15.48 | %
Tier 1 Capital to Risk Weighted Assets | 8.50 | % |  | 13.93 | % |  | 15.48 | %
Total Capital to Risk Weighted Assets | 10.50 | % |  | 17.44 | % |  | 16.45 | %
Leverage Ratio of Tier 1 Capital to Average Assets | 6.50 | % |  | 10.08 | % |  | 11.19 | %

Management believes that no conditions or events have occurred since December 31, 2023, that would materially adversely change First Busey’s or Busey Bank’s capital classifications.
NEW ACCOUNTING PRONOUNCEMENTS

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, 2023—Consolidated Average Balance Sheets and Interest Rates” and “Item 7A. Quantitative and Qualitative Disclosures About Market Risk.”
First Busey Corporation | 2023 — 89

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 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 basis points. 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, 2023 |  | December 31, 2022 |  | December 31, 2023 |  | December 31, 2022
+400 | 7.38 | % |  | 12.27 | % |  | 8.55 | % |  | 16.02 | %
+300 | 5.49 | % |  | 9.18 | % |  | 6.34 | % |  | 11.94 | %
+200 | 3.64 | % |  | 6.11 | % |  | 4.20 | % |  | 7.91 | %
+100 | 1.81 | % |  | 3.05 | % |  | 2.10 | % |  | 3.94 | %
- 100 | (1.91) | % |  | (3.95) | % |  | (2.98) | % |  | (5.27) | %
-200 | (3.86) | % |  | (8.08) | % |  | (6.12) | % |  | (10.76) | %
-300 | (5.60) | % |  | (14.74) | % |  | (9.17) | % |  | (19.56) | %
-400 | (6.91) | % |  | (21.24) | % |  | (11.36) | % |  | (27.82) | %

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
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, 2023 and 2022, 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, 2023, 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, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, 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, 2023, 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 22, 2024, 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 3 to the financial statements, the Company’s allowance for credit losses totaled $91.7 million, which consists of a reserve on loans collectively evaluated for impairment (a/k/a general reserve) of $90.8 million and a reserve on loans individually evaluated (a/k/a specific reserve) of $.9 million at December 31, 2023. 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
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.
Significant accounting and reporting policies for First Busey Corporation and its subsidiaries follow:
Principles of Consolidation
Busey’s Consolidated Financial Statements include the accounts of First Busey Corporation and its subsidiaries, which include First Busey Risk Management (dissolved December 18, 2023), Deed of Trust Services Corporation, and Busey Bank, including Busey Bank’s wholly-owned subsidiaries FirsTech, Pulaski Service Corporation, and Busey Capital Management, Inc. 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, and Pulaski Financial Statutory Trust II.
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 in 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 debt securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.
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).

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
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 $12.1 billion at December 31, 2023, and $11.1 billion at December 31, 2022.
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.
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.
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);
First Busey Corporation | 2023 — 101

Table of Contents Contents of Item 8. Financial Statements & Supplementary Data
FIRST BUSEY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
•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 in 2023, 2022, or 2021.
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 related to mortgage-backed securities issued and/or guaranteed by U.S. government agencies or U.S. government-sponsored enterprises is considered low, therefore requiring no allowance to be recorded.
Accrued interest receivable for debt securities totaled $13.6 million at December 31, 2023, 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 $1.5 billion as of December 31, 2023, and $1.7 billion as of December 31, 2022, and are not included in the accompanying Consolidated Balance Sheets. Servicing rights are initially recorded at 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 loans is included in other income.
First Busey Corporation | 2023 — 102

Table of Contents Contents of Item 8. Financial Statements & Supplementary Data
FIRST BUSEY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Servicing rights are periodically evaluated for impairment based on the fair value of those rights as compared to book value. 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, 2023 and 2022.
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.
PPP Loans
Busey had $0.3 million in PPP loans outstanding as of December 31, 2023. In comparison, Busey had $0.9 million in PPP loans outstanding as of December 31, 2022, with an amortized cost of $0.8 million. Busey received an immaterial amount of fees related to these loans for the year ended December 31, 2023, and received fees totaling $2.5 million and $20.1 million for the years ended December 31, 2022, and 2021, respectively. Incremental direct origination costs Busey incurred were immaterial for the year ended December 31, 2023, and were $0.6 million and $4.2 million for the years ended December 31, 2022, and 2021, respectively.
Both the fees received and the origination costs were deferred and are amortized over the contractual life of these loans, subject to prepayment. Busey recognized an immaterial amount in net interest income for fees, net of deferred cost, during the year ended December 31, 2023, and recognized $1.9 million and $14.0 million during the years ended December 31, 2022, and 2021, respectively. As of December 31, 2023, the remaining amount of fees to be recognized, net of deferred costs, was immaterial. PPP loans contain a forgiveness feature for funds spent on covered expenses, including both principal and accrued interest. Any remaining balance after loan forgiveness maintains a 100% government guarantee for the remaining term of the loan.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Loan Modifications
On January 1, 2023, Busey adopted ASU 2022-02 “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,” which eliminated the TDR accounting model for creditors that have already adopted CECL. In lieu of the TDR accounting model, 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” will apply to all loan modifications, including those made for borrowers experiencing financial difficulty. This standard also enhances disclosure requirements related to certain loan modifications.
Assets Purchased with Credit Deterioration
On January 1, 2020, Busey adopted ASC Topic 326 “Financial Instruments-Credit Losses” using the prospective transition approach for financial assets 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. In accordance with ASC Topic 326, the amortized cost basis of PCD assets were adjusted to reflect an ACL for any remaining credit discount. Subsequent changes in expected cash flows will be adjusted through the ACL. The noncredit discount will be accreted into interest income using the January 1, 2020, effective interest rate.
Subsequent to the adoption of ASC Topic 326, acquired loans are separated into two categories based on the credit risk characteristics of the underlying borrowers as either PCD, for loans which have experienced more than insignificant credit deterioration since origination, or all other loans. At the date of acquisition, an ACL on PCD loans is determined and netted against the amortized cost basis of the individual loans. 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 through provision expense. For all other loans, an ACL is established immediately after the acquisition through a charge to the provision for credit losses.
Allowance for Credit Losses
The ACL is a significant estimate in 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 uncollectibility of a loan balance is confirmed. 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, 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. 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 18. Fair Value Measurements.”

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
Our 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, we may conclude 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.
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

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 our incremental borrowing rate.
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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
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.
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.
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.
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. Busey has established December 31 as the annual impairment assessment date. As part of this analysis, 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, 2023, or 2022. See “Note 7. Goodwill and Other Intangible Assets” for further discussion.
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.
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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
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 $5.6 million as of both December 31, 2023, and 2022. Liabilities for post-employment benefits are included in other liabilities on the Consolidated Balance Sheets.
FHLB Stock
Busey Bank is a member of the FHLB system. FHLB members are required to own a certain amount of stock based on the level of borrowings and other factors, and may invest in additional amounts. FHLB stock is carried at cost in other assets in our Consolidated Balance Sheet. Dividends are reported as income.
Busey Bank's investment in FHLB stock was $6.0 million as of December 31, 2023, and $19.0 million as of December 31, 2022.
Other Asset Investments
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, deferral, or proportional amortization practical expedient methods, as appropriate. 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.
The following table summarizes the impact of Busey’s other asset investments on the Company’s Consolidated Balance Sheets for the periods indicated (dollars in thousands):

|  |  |  | As of December 31,
|  | Location |  | 2023 |  | 2022
Other asset investments |  |  |  |  |  |
Funded investments |  | Other assets |  | $ | 68,516 |  |  | $ | 58,912 |

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.
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 and require significant judgment to apply. Busey is no longer subject to U.S. federal, state, or local income tax examinations by tax authorities for the years before 2020.
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.
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, 2023, or 2022.
Positions taken in tax returns may be subject to challenge upon examination by the taxing authorities. Uncertain tax positions are initially recognized in 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. Busey had no accruals for payments of interest and penalties at December 31, 2023, or 2022.
At December 31, 2023, Busey was not under any income tax examination by any income tax authority.
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. All of Busey’s employees and directors and those of its subsidiaries are eligible to receive awards under the plans.

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.
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. 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 market or other performance goals 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.
DSU Awards
Busey grants DSU awards to its directors and advisory 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, 2023, were fully vested.

2021 Employee Stock Purchase Plan
The 2021 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. One of the primary purposes of the 2021 ESPP is to provide a means through which our associates may acquire a proprietary interest in Busey by purchasing shares of our common stock at a discounted price through voluntary payroll deductions, further incentivizing Busey associates to exert maximum effort toward Busey’s success.
Because the 2021 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 14. Stock-based Compensation” for further discussion.
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 operations are managed along three operating segments consisting of Banking, Wealth Management, and FirsTech. See “Note 21. Operating Segments and Related Information” for further discussion.
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.
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.
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.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
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 in 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 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 in 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 current earnings 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 of the customer swap as of the default date. If the customer swap has a negative fair value, 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.

•A counterparty has a swap agreement with a customer. Busey (seller) entered into a risk participation with a counterparty (purchaser), under which Busey receives a fee to accept a portion of the credit risk. If the counterparty’s customer defaults on the swap contract, Busey must reimburse the counterparty (purchaser) for Busey's percentage of the positive fair value of the customer swap as of the default date. If the customer swap has a negative fair value, Busey has no reimbursement requirements. If the counterparty’s customer defaults on the swap contract and Busey (seller) fulfills its payment obligations under the risk participation agreement, Busey (seller) is entitled to a pro rata share of the counterparty’s claim against the customer under the terms of the swap agreement.
Foreign Currency Forward Contracts
Busey entered into foreign currency exchange contracts to support the business requirements of its customers. Foreign currency contracts involve the exchange of one currency for another on a specified date and at a specified rate. These contracts are executed on behalf of Busey's customers and are used by customers to manage fluctuations in foreign exchange rates. Busey minimizes its exposure by entering into similar offsetting positions with other financial institutions. Busey is subject to the credit risk that another party will fail to perform.
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 in 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.

FIRST BUSEY CORPORATION
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
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 $7.1 million as of December 31, 2023, and $6.6 million as of December 31, 2022.
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 18. 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.
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, 2023.
Impact of Recently Adopted Accounting Standards
In July 2023, the FASB issued ASU 2023‑03 “Presentation of Financial Statements (Topic 205), Income Statement—Reporting Comprehensive Income (Topic 220), Distinguishing Liabilities from Equity (Topic 480), Equity (Topic 505), and Compensation—Stock Compensation (Topic 718)” pursuant to: (1) SEC Staff Accounting Bulletin No. 120, which provided interpretive guidance related to estimating the fair value of share-based payment transactions while in possession of material non-public information; (2) an SEC Staff Announcement at the March 24, 2022, Emerging Issues Task Force Meeting, which provided interpretive guidance on accounting for share-based payments to employees and non-employees; and (3) Staff Accounting Bulletin Topic 6.B, Accounting Series Release 280—General Revision of Regulation S-X: Income or Loss Applicable to Common Stock, which provided interpretive guidance on the reporting of income or loss applicable to common stock. This update was reflected in the Accounting Standards Codification upon issuance. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.
In March 2022, the FASB issued ASU 2022‑02 “Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures,” which eliminates the TDR accounting model for creditors that have already adopted CECL. In lieu of the TDR accounting model, 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” will apply to all loan modifications, including those made for borrowers experiencing financial difficulty. This standard also enhances disclosure requirements related to certain loan modifications. Additionally, this standard introduces new requirements to disclose gross write-off information in the vintage disclosures of financing receivables by credit quality indicator and class of financing receivable by year of origination. This standard applies prospectively. For the transition method related to the recognition and measurement of TDRs, there is an option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings in the period of adoption. This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
In March 2022, the FASB issued ASU 2022‑01 “Derivatives and Hedging (Topic 815): Fair Value Hedging—Portfolio Layer Method,” which replaces the current last-of-layer hedge accounting method with an expanded portfolio layer method that permits multiple hedged layers of a single closed portfolio. The scope of the portfolio layer method is also expanded to include non-prepayable financial assets. This update also provides additional guidance on the accounting for and disclosure of hedge basis adjustments that are applicable to the portfolio layer method, and specifies how hedge basis adjustments should be considered when determining credit losses for the assets included in the closed portfolio. Amendments related to hedge basis adjustments which are included in this standard apply on a modified retrospective basis by means of a cumulative-effect adjustment to the opening balance of retained earnings on the initial application date. Amendments related to disclosure which are included in this standard may be applied on a prospective basis from the initial application date, or on a retrospective basis to each prior period presented after the date of adoption of the amendments in ASU 2017-12 “Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities.” This standard became effective for Busey beginning January 1, 2023. Adoption of this standard did not have a material impact on Busey’s financial position or results of operations.
ASU 2021‑08 “Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers” requires measurement and recognition in accordance with ASC Topic 606 “Revenue from Contracts with Customers” for contract assets and contract liabilities acquired in a business combination. This update became effective for Busey beginning January 1, 2023. This standard applied prospectively to all business combinations that occurred on or after the date of adoption. Adoption of this standard did not have an impact on Busey’s financial position or results of operations.
Recently Issued Accounting Standards Not Yet Adopted
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 periods beginning on January 1, 2025. Busey does not expect adoption of this standard to have a material impact on the Company’s financial position or results of operations.
In November 2023, the FASB issued ASU 2023‑07 “Segment Reporting Topic 820): Improvements to Reportable Segment Disclosures” requiring enhanced disclosures related to significant segment expenses. This standard is to be applied on a retrospective basis, and is effective for Busey beginning with its fiscal year starting on January 1, 2024, and for interim reporting periods within fiscal years starting January 1, 2025. Busey does not expect adoption of this standard to have a material impact on the Company’s 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 accounting standards update will be the date on which the SEC removes the related disclosure from Regulation S‑X or Regulation S‑K. Early adoption is prohibited. Busey does not expect adoption of this standard to have a material impact on the Company’s financial position or results of operations.

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. This standard must be applied on a retrospective or modified retrospective basis, and became effective for Busey beginning on January 1, 2024. Busey recorded an after-tax decrease to retained earnings of $1.4 million as of January 1, 2024, 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. This standard may be adopted either prospectively, or retrospectively, and became effective for Busey beginning January 1, 2024. Busey does not expect adoption of this standard to have a material impact on the Company’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. This standard applies prospectively, and became effective for Busey beginning January 1, 2024. Busey does not expect adoption of this standard to have a material impact on the Company’s 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. There were no significant subsequent events for the year ended December 31, 2023, through the filing date of these Consolidated Financial Statements.

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, 2023, Busey did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of the Company’s stockholders’ equity.

•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 $6.1 million and $14.0 million of collateral dependent loans secured by real estate or business assets as of December 31, 2023, and December 31, 2022, 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. PPP loans were excluded from the ACL calculation as they are 100% government guaranteed.
The following table summarizes activity in the ACL attributable to each loan class. Allocation of a portion of the ACL to one loan class does not preclude its availability to absorb losses in other loan classes (dollars in thousands):

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 loans now have an annual interest rate of 1.80% plus the one-month forward-looking term rate based on SOFR. On April 30, 2023, the agreement was further amended to extend the term for the revolving line of credit to April 30, 2024.
Proceeds of the Term Loan were used to fund a part of the cash portion of the merger consideration related to the acquisition of CAC in the second quarter of 2021, and for general corporate purposes. The total outstanding balance on the Term Loan was $30.0 million as of December 31, 2023, of which $12.0 million was short-term and $18.0 million was long-term. Quarterly payments on the Term Loan reduce the outstanding principal balance by $3.0 million each quarter.
As of December 31, 2023, there was no balance outstanding on the revolving credit facility. The revolving credit facility incurs a non-usage fee based on any undrawn amounts.

The subordinated notes are 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.

NOTE 10. 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. In connection with the Pulaski acquisition in 2016, Busey acquired similar statutory trusts previously maintained by Pulaski and the fair value adjustment is being accreted over their weighted average remaining life, with a balance of $2.6 million remaining to be accreted. Busey had $72.0 million and $71.8 million of junior subordinated debt owed to unconsolidated trusts at December 31, 2023, and 2022, respectively, maturing in 2034 through 2036.
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, 2023, 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 11. REGULATORY CAPITAL
Busey and its subsidiary bank are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory—and possibly additional discretionary—actions by regulators that, if undertaken, could have a direct material effect on 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, 2023, and December 31, 2022, all capital ratios of Busey and its subsidiary 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, 2023, 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 our 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 our 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 $90.0 million, $95.0 million, and $60.0 million in dividends to First Busey Corporation during the years ended December 31, 2023, 2022, and 2021, respectively.

NOTE 13. EMPLOYEE BENEFIT PLANS
401(k) Plan
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. The 401(k) Plan is funded primarily through participant contributions via payroll deductions. The 401(k) Plan offers two contribution options: (1) the traditional option allows plan participants to elect pre-tax contributions, and (2) the Roth option allows plan participants to elect after tax contributions. 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 contributions and 50% of the next 2% of eligible participant contributions. The rights of participants in Safe Harbor matching contributions vest immediately.
Profit Sharing
All associates who meet certain age and service requirements are eligible to participate in Busey's profit-sharing contributions. Discretionary profit-sharing contributions and related expenses, if any, are approved solely by the First Busey Corporation board of directors, and in no case may annual contributions be greater than the amounts deductible for federal income tax purposes for that year. The rights of participants in profit-sharing contributions vest ratably over a five-year period.

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. An amendment and restatement of the 2020 Equity Plan was approved by stockholders at the 2023 Annual Meeting of Stockholders. 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.
Under the terms of the 2020 Equity Plan, Busey has granted RSU, PSU, and DSU awards. Upon vesting and delivery, shares are expected, though not required, to be issued from treasury.
A description of RSU, PSU, and DSU awards granted in 2023 under the terms of the 2020 Equity Plan is provided below. A description of RSU, PSU, and DSU awards granted in 2022 and 2021 under the terms of the 2020 Equity Plan can be found in Busey’s Annual Reports for the years ended December 31, 2022, and 2021, respectively.
Busey issued 132,091 treasury shares in conjunction with the vesting of RSUs and PSUs, and settlement of DSUs in 2023. 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 1,723,343 shares available for issuance under the 2020 Equity Plan as of December 31, 2023.
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.

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 22, 2023, under the terms of the 2020 Equity Plan, Busey granted a target of 104,643 PSUs with a maximum award of 167,429 units.

Franchise Tax Matter
In 2021, Busey received an inquiry from the ISOS, pursuant to which the ISOS asked for additional information regarding certain of our 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 agreed to prepare additional BCA forms requested by the ISOS, 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 us 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, 2023. 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 17. 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 18. 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):

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 $350.0 million as of both December 31, 2023, and December 31, 2022, were designated as cash flow hedges. Busey entered into one $50.0 million interest rate swap to hedge the risks of variability in cash flows for future interest payments attributable to changes in the contractually specified 3-month LIBOR benchmark interest rate on Busey’s junior subordinated debt owed to unconsolidated trusts (“Debt Swap”). In addition, Busey entered into one $300.0 million receive fixed pay floating interest rate swap to reduce Busey's asset sensitivity (“Loan Swap”). Duration was added to our loan portfolio by fixing a portion of our 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. Changes in fair value were recorded net of tax in OCI.

Derivative Instruments Not Designated as Hedges
Interest Rate Swaps
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 $663.1 million and $576.9 million as of December 31, 2023, and 2022, 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.
Amounts and fair values of derivative assets and liabilities related to customer interest rate swaps, included in other assets and other liabilities in the Consolidated Balance Sheets, are summarized as follows (dollars in thousands):

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 a portion of the credit exposure, paying an up-front fee, and will receive a payment from the counterparty if the loan customer defaults on its obligations.
Busey also entered into a risk participation agreement under which Busey sold a portion of its credit exposure, receiving an up-front fee, and will be required to make a payment to the counterparty if the loan customer defaults on its obligations.
The notional amount of the risk participation agreements reflect Busey's pro-rata share of the derivative instrument, consistent with its share of the related participated loan. The risk participation agreements mature between 2024 and 2029, and are summarized as follows (dollars in thousands):

Foreign Currency Forward Contracts
In 2023, Busey entered into foreign currency exchange contracts to support the business requirements of its customers. Foreign currency contracts involve the exchange of one currency for another on a specified date and at a specified rate. These contracts were executed on behalf of Busey's customers and were used by customers to manage fluctuations in foreign exchange rates. Busey minimized its exposure by entering into similar offsetting positions with other financial institutions. Busey was subject to the credit risk that another party would fail to perform. As of December 31, 2023, Busey had no derivative assets or derivative liabilities related to foreign currency contracts recorded in its Consolidated Balance Sheets.
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 in 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 in 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.

In 2021, the impact of the net gains or losses recognized in earnings on interest rate lock commitments and forward sales commitments was almost entirely offset by the recognition of a corresponding change in the fair value of loans held for sale. In 2022, Busey began carrying loans held for sale at LOCOM, so while Busey will continue to recognize gains or losses on these mortgage banking derivative instruments in earnings, 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 will continue to be recognized in earnings at each measurement period.

NOTE 18. 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, volatilities, 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 is based upon quoted market prices, when available. If such quoted market prices are not available, fair values are measured utilizing independent valuation techniques of 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 fair value. 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 determine 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 utilizing 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, focusing on observable market data such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing, to prepare evaluations.
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.
First Busey Corporation | 2023 — 161

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 utilizing Level 1 or Level 2 inputs. Fair value measurements of mutual funds, when held, are determined using unadjusted quoted prices in active markets for identical assets at the measurement date and are classified as Level 1. For stock, quoted prices for identical or similar assets in markets that are not active are utilized and classified as Level 2.
Derivative Assets and Derivative Liabilities
The majority of our derivative assets and derivative liabilities are reported at fair value utilizing 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 determined based on prices that are obtained from a third-party which uses observable market inputs and, with the exception of our risk participation agreements, are classified as Level 2. For purposes of potential valuation adjustments to our 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 our 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 fair value on a non-recurring basis; that is, the instruments are not measured at 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 fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the 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 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.

NOTE 19. EARNINGS PER SHARE
Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding, which include DSUs that are vested but not delivered. Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if Busey’s outstanding stock options and warrants were exercised, stock units were vested, and shares were issued under the 2021 ESPP.
Earnings per common share have been computed as follows (dollars in thousands, except per share amounts):

NOTE 23. ACQUISITIONS
Merchants and Manufacturers Bank Corporation
On November 27, 2023, First Busey Corporation announced the signing of a definitive agreement with M&M, pursuant to which Busey will acquire M&M and its wholly-owned subsidiary, M&M Bank, through a merger transaction. This partnership will add M&M’s Life Equity Loan® products to Busey’s existing suite of services, and expand Busey’s presence in the Chicago Metropolitan Statistical Area.
Under the terms of the merger agreement, M&M’s stockholders will have the right to receive for each share of M&M common stock, at the election of each stockholder and subject to proration and adjustment, either (1) $117.74 in cash, (2) 5.7294 shares of Busey common stock, or (3) mixed consideration of $34.55 in cash and 4.0481 shares of Busey common stock, with total consideration to consist of approximately 71% stock and 29% cash. Based upon Busey’s 20‑day volume-weighted average closing price as of November 24, 2023, the aggregate implied transaction value is approximately $41.6 million.
The merger is expected to be finalized in the second quarter of 2024, subject to customary closing conditions and required approvals, including regulatory approvals and the approval of M&M’s stockholders. It is anticipated that M&M Bank will be merged with and into Busey Bank at a date following the completion of the merger. At the time of the bank merger, M&M Bank’s banking centers will become banking centers of Busey Bank, except for M&M’s banking center located at 990 Essington Rd., Joliet, Illinois, which is expected to be closed in connection with the bank merger.
This transaction will be accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged will be recorded at estimated fair values on the date of acquisition. Fair values will be subject to refinement for up to one year after the closing date as additional information regarding the closing date fair values becomes available. During 2023, Busey incurred $0.3 million in pre-tax acquisition expenses, comprised primarily of legal expenses, related to the planned acquisition of M&M.

An evaluation of our disclosure controls and procedures, as defined in Rule 13a-15(e) under the Exchange Act, was carried out as of December 31, 2023, under the supervision and with the participation of our Chief Executive Officer, Chief Financial Officer, and several other members of our senior management. Based on this evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of December 31, 2023, our disclosure controls and procedures were effective in ensuring that the information we are required to disclose in the reports we file or submit under the Exchange Act was (1) accumulated and communicated to our 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, 2023, no change occurred in our internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, our 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, 2023, 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, 2023, 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, 2023. The report, which expresses an unqualified opinion on the effectiveness of Busey’s internal control over financial reporting as of December 31, 2023, is included in this Item under the heading “Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting.”

To the Stockholders and the Board of Directors of First Busey Corporation
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, 2023, 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, 2023, 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, 2023 and 2022, 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, 2023, and the related notes to the consolidated financial statements and our report dated February 22, 2024 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.
