### Banking Center Markets

Busey Bank has 46 banking centers in Illinois. Our Illinois markets feature several Fortune 1000 companies. Those organizations, coupled with large healthcare and higher education sectors, anchor the communities in which they are located and have provided a comparatively stable foundation for housing, employment, and small business. Historically, the financial condition of the state of Illinois, in which the largest portion of Busey Bank’s customer base resides, has been characterized by low credit ratings and budget deficits. However, with the recent improvement in the state’s financial outlook, during the second half of 2021 Illinois received improved ratings from Moody’s Investor Service, S&P Global Ratings, and Fitch.

Busey Bank has eight banking centers in Missouri. St. Louis, Missouri has a diverse economy with major employment sectors including health care, financial services, professional and business services, and retail. Twelve of our banking centers in Illinois are located within the boundaries of the St. Louis Metropolitan Statistical Area.

Busey Bank has three banking centers in southwest Florida, an area which has experienced above average population growth, job growth, and an expanded housing market over the last several years.

Busey Bank has one banking center in the Indianapolis, Indiana area, which is the most populous city of Indiana with a diverse economy, including the headquarters of many large corporations.

In November 2021, First Busey completed its previously announced service center closures as part of our Personal Banking Transformation Plan, which resulted in the consolidation of 17 branches across our various markets.

### 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, fintech 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, 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 interbranch deposit and withdrawal privileges.

Based on information obtained from the FDIC Summary of Deposits dated June 30, 2021, the most recent report available, Busey Bank ranked in the top 10 in total deposits in 12 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, the Company’s growth and earnings performance may be affected not only by management decisions 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 the Company’s business. The effect of these statutes, regulations, regulatory policies, and accounting rules are significant to the Company’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 the Company’s business; the kinds and amounts of investments the Company 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 the Company’s and Busey Bank’s insiders and affiliates; and the Company’s payment of dividends.

In reaction to the global financial crisis and particularly following the passage of the Dodd-Frank Act in 2010, the Company 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 $10.0 billion in assets and the influence of other provisions filtered down in varying degrees to community banks over time, causing the Company’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 $10.0 billion threshold remained in place for certain Dodd-Frank Act reforms that are now applicable to the Company, 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 the Company 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.

### COVID-19 Pandemic

Federal bank regulatory agencies, along with their state counterparts, issued a steady stream of guidance responding to the COVID-19 pandemic and they took a number of unprecedented steps to help banks navigate the pandemic and mitigate its impact. These included, without limitation: requiring banks to focus on business continuity and pandemic planning; adding pandemic scenarios to stress testing; encouraging bank use of capital buffers and reserves in lending programs; permitting certain regulatory reporting extensions; reducing margin requirements on swaps; permitting certain otherwise prohibited investments in investment funds; issuing guidance to encourage banks to work with customers affected by the pandemic; and providing credit under the CRA for certain pandemic-related loans, investments, and public service. Because of the need for social distancing measures, the agencies revamped the manner in which they conducted periodic examinations of their regulated institutions, including making greater use of off-site reviews, and they have continued virtual examinations in 2022.

Reference is made to “*Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Impact of COVID-19”* below for further information on the impact of the COVID-19 pandemic. In addition, information as to selected topics is contained in the relevant sections of this Supervision and Regulation discussion provided below.

### The $10.0 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 $10.0 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 $10.0 billion and $50 billion, but the other Dodd-Frank regulations and reporting requirements were not changed.

The Company crossed the $10.0 billion threshold in 2020. However, the federal bank regulatory agencies issued an Interim Final Rule on November 20, 2020, that provided temporary relief for certain community banking organizations as a result of growth in size from the COVID-19 response. That relief expired December 31, 2021.

The material consequences to the Company of crossing the $10.0 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. Durbin limitations are applicable to any banking entity with over $10.0 billion in assets and will be applicable to Busey Bank after a six-month transition period. Management believes that compliance with Durbin will materially reduce Busey Bank’s earnings on the covered debit transactions.

#### 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 $10.0 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 $10.0 billion threshold. The Company 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 the operations of the Company and its subsidiaries.

#### CFPB Examination and Enforcement

Although 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 $10.0 billion in assets (measured over four consecutive quarters). Busey Bank continues to be examined for compliance with consumer laws by its primary federal regulatory agency, the FDIC, but the CFPB is in the process of assuming supervisory authority in that regard.

#### Clearing Swaps Agreements

Banks with over $10.0 billion in assets are required to clear swaps agreements on exchanges. The requirement was not deferred by the Interim Final Rule. 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 $10.0 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 $50.0 billion. Although it is not yet required to have a risk committee in place, the Company 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, which directly affects the Company’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.

#### 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.” The capital guidelines for U.S. banks beginning in 1989 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 regulatory capital reforms in pertinent part, and, at the same time, promulgated rules effecting certain changes required by the Dodd-Frank Act (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: it increased the required quantity and quality of capital; and it required a more complex, detailed, and calibrated assessment of risk in the calculation of risk weightings. 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. The Company and the Bank are each subject to the Basel III Rule as described below.

Not only did the Basel III Rule increase most of the required minimum capital ratios in effect prior to January 1, 2015, but also, in requiring that forms of capital be of higher quality to absorb loss, it 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 in the event that such assets exceeded a percentage of a banking institution’s Common Equity Tier 1 Capital.

#### Minimum Capital Ratio Requirements

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;
- 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 seek the freedom 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. Federal bank regulators released a joint statement in response to the COVID-19 pandemic reminding the industry that capital and liquidity buffers were meant to give banks the means to support the economy in adverse situations, and that the agencies would support banks that use the buffers for that purpose if undertaken in a safe and sound manner.

#### 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: (i) qualify for exemptions from prior notice or application requirements otherwise applicable to certain types of activities; (ii) qualify for expedited processing of other required notices or applications; and (iii) 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
- 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, 2021: (i) Busey Bank was not subject to a directive from the FDIC to increase its capital and (ii) Busey Bank was well-capitalized, as defined by FDIC regulations. As of December 31, 2021, the Company had regulatory capital in excess of the Federal Reserve’s requirements and met the requirements to be well-capitalized. The Company 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: (i) requiring the institution to submit a capital restoration plan; (ii) limiting the institution’s asset growth and restricting its activities; (iii) requiring the institution to issue additional capital stock (including additional voting stock) or to sell itself; (iv) restricting transactions between the institution and its affiliates; (v) restricting the interest rate that the institution may pay on deposits; (vi) ordering a new election of directors of the institution; (vii) requiring that senior executive officers or directors be dismissed; (viii) prohibiting the institution from accepting deposits from correspondent banks; (ix) requiring the institution to divest certain subsidiaries; (x) prohibiting the payment of principal or interest on subordinated debt; and (xi) ultimately, appointing a receiver for the institution.

### Supervision and Regulation of the Company

#### General

The Company, as the sole stockholder of Busey Bank, is a bank holding company. As a bank holding company, the Company is registered with, and subject to regulation, supervision, and enforcement by, the Federal Reserve under the BHCA. The Company 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, the Company 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 the Company 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 the Company 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 the Company 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, the operation of a computer service bureau (including software development) 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. The Company has elected to operate as a financial holding company. In order to maintain its status as a financial holding company, the Company 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

The Company’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, the Company is subject to the limitations of Nevada law, which allows the Company to pay dividends unless, after such dividend, (i) the Company would not be able to pay its debts as they become due in the usual course of business or (ii) the Company’s total assets would be less than the sum of its total liabilities plus any amount that would be needed, if the Company were to be dissolved at the time of the dividend payment, to satisfy the preferential rights upon dissolution of stockholders whose rights are superior to the rights of the stockholders receiving the distribution.

As a general matter, the Federal Reserve has indicated that the board of directors of a bank holding company should eliminate, defer or significantly reduce dividends to stockholders if: (i) 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; (ii) the prospective rate of earnings retention is inconsistent with the company’s capital needs and overall current and prospective financial condition; or (iii) 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. Layered on top of that are the abuses in the headlines dealing with product cross-selling incentive plans. The result is interagency guidance on sound incentive compensation practices.

The interagency guidance recognized three core principles. Effective incentive plans should: (i) provide employees incentives that appropriately balance risk and reward; (ii) be compatible with effective controls and risk-management; and (iii) 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 the Company, 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, and this has come into play during 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

The Company’s common stock is registered with the SEC under the Securities Act and the Exchange Act. Consequently, the Company 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 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. FDIC assessment rates for institutions that have more than $10.0 billion in assets, such as Busey Bank, are calculated based on a “scorecard” methodology that seeks to capture both the probability that an individual large institution will fail and the magnitude of the impact on the DIF if such a failure occurs, based primarily on the difference between the institution’s average of total assets and average tangible equity. The FDIC has the ability to make discretionary adjustments to the total score, up or down, based upon significant risk factors that are not adequately captured in the scorecard. For institutions like Busey Bank, after accounting for potential base-rate adjustments, the total assessment rate could range from 1.5 to 40 basis points on an annualized basis. An institution’s assessment is determined by multiplying its assessment rate by its assessment base, which is asset based.

The reserve ratio is the FDIC insurance fund balance divided by estimated insured deposits. The Dodd-Frank Act altered the minimum reserve ratio of the DIF, increasing the minimum from 1.15% to 1.35% of the estimated amount of total insured deposits. The reserve ratio reached 1.36% as of September 30, 2018. As a result, the FDIC provided assessment credits to insured depository institutions, like Busey Bank at the time, with total consolidated assets of less than $10.0 billion for the portion of their regular assessments that contributed to growth in the reserve ratio between 1.15% and 1.35%. The FDIC applied the small bank credits for quarterly assessment periods beginning July 1, 2019. However, the reserve ratio fell to 1.30% in 2020 because of extraordinary insured deposit growth caused by an unprecedented inflow of more than $1.0 trillion in estimated insured deposits in the first half of 2020, stemming mainly from the COVID-19 pandemic. Although the FDIC could have ceased the small bank credits, it waived the requirement that the reserve ratio be at least 1.35% for full remittance of the remaining assessment credits, and it refunded all small bank credits as of September 30, 2020.

The DIF balance was $121.9 billion on September 30, 2021, up $1.4 billion from the end of the second quarter. The reserve ratio remained at 1.27%, as growth in the fund balance kept pace with growth in insured deposits. The FDIC staff continues to closely monitor the factors that affect the reserve ratio, and any change could impact FDIC assessments.

#### 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, 2021, Busey Bank paid supervisory assessments to the DFPR totaling approximately $0.8 million.

#### Capital Requirements

Banks are generally required to maintain capital levels in excess of other businesses. For a discussion of capital requirements, see “*Item 1. Business—Supervision, Regulation and Other Factors—The Role of Capital”* above.

#### Liquidity Requirements

Liquidity is a measure of the ability and ease with which bank assets may be converted to cash. Liquid assets are those that can be converted to cash quickly if needed to meet financial obligations. To remain viable, FDIC-insured institutions must have enough liquid assets to meet their near-term obligations, such as withdrawals by depositors. Because the global financial crisis was in part a liquidity crisis, Basel III also includes a liquidity framework that requires FDIC-insured institutions to measure their liquidity against specific liquidity tests. One test, referred to as the LCR, 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 NSFR, 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).

In addition to liquidity guidelines already in place, federal bank regulatory agencies implemented the Basel III LCR in September 2014, which requires large financial firms to hold levels of liquid assets sufficient to protect against constraints on their funding during times of financial turmoil, and in 2016 proposed implementation of the NSFR. While these rules do not, and will not, apply to Busey Bank, it continues to review its liquidity risk management policies in light of developments.

#### Dividend Payments

The primary source of funds for the Company 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.” The Company is an affiliate of Busey Bank for purposes of these restrictions, and covered transactions subject to the restrictions include extensions of credit to the Company, investments in the stock or other securities of the Company, and the acceptance of the stock or other securities of the Company 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 the Company and its subsidiaries, to principal stockholders of the Company, 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 the Company or Busey Bank, or a principal stockholder of the Company, 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.

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 2022 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: (i) regulatory approval; (ii) federal and state deposit concentration limits; and (iii) 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.

#### Transaction Account Reserves

Federal law requires FDIC-insured institutions to maintain reserves against their transaction accounts (primarily NOW and regular checking accounts) to provide liquidity. The amount of reserves is determined by the Federal Reserve based on tranches of zero, three, and ten percent of a bank’s transaction account deposits. However, in March 2020, in an unprecedented move, the Federal Reserve announced that the banking system had ample reserves, and, as reserve requirements no longer played a significant role in this regime, it reduced all reserve tranches to zero percent, thereby freeing banks from the legally mandated reserve maintenance requirement. The action permits Busey Bank to loan or invest funds that previously were unavailable. The Federal Reserve has indicated that it expects to continue to operate in an ample reserves regime for the foreseeable future.

#### 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. Applications for additional acquisitions would be affected by the evaluation of Busey Bank’s effectiveness in meeting its CRA requirements. In a joint statement responding to the COVID-19 pandemic, the bank regulatory agencies announced favorable CRA consideration for banks providing retail banking services and lending activities in their assessment areas, consistent with safe and sound banking practices, that are responsive to the needs of low- and moderate-income individuals, small businesses, and small farms affected by the pandemic. Those activities include waiving certain fees, easing restrictions on out-of-state and non-customer checks, expanding credit products, increasing credit limits for creditworthy borrowers, providing alternative service options, and offering prudent payment accommodations. The joint statement also provided favorable CRA consideration for certain pandemic-related community development activities.

#### Anti-Money Laundering

The USA PATRIOT Act, the Bank Secrecy Act and other similar laws 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. These laws mandate financial services companies to have policies and procedures with respect to measures designed to address the following matters: (i) customer identification programs; (ii) money laundering; (iii) terrorist financing; (iv) identifying and reporting suspicious activities and currency transactions; (v) currency crimes; and (vi) 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: (i) CRE loans exceeding 300% of capital and increasing 50% or more in the preceding three years; or (ii) 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, 2021, 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 $10.0 billion in assets. The CFPB is in the process of assuming supervisory authority over Busey Bank in that regard.

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. The CFPB’s rules have not had a significant impact on the Bank’s operations, except for higher compliance costs.

### Supervision and Regulation of Busey Risk Management

Associate engagement is an important barometer of our cultural health. We regularly solicit feedback and understand views of our associates about their work environment and Busey’s culture. The results from engagement surveys are used to implement programs and processes designed to enhance engagement and improve the associate experience. One such way to keep associates informed and engaged is through our quarterly update calls, which are conducted by Busey leadership. The recordings are available for all associates. These calls provide important information about the financial health of the company, but more importantly they provide a cultural touchpoint to solidify Busey’s commitment to our number one asset – our associates. A tenet of our engaged culture is a commitment to investing in associates through unique, award-winning training and development programs. In 2021, 51% of our associate base engaged in talent and leadership development programs.

Management uses these non-GAAP measures, together with the related GAAP measures, to analyze the Company’s performance and to make business decisions. Management also uses these measures for peer comparisons.

A reconciliation to what management believes to be the most direct compared GAAP financial measures, specifically total net interest income in the case of pre-provision net revenue, adjusted pre-provision net revenue, pre-provision net revenue to average assets, and adjusted pre-provision net revenue to average assets; net income in the case of adjusted net income, adjusted diluted earnings per share, and adjusted return on average assets; total net interest income in the case of adjusted net interest margin; total noninterest income and total noninterest expense in the case of adjusted noninterest expense, efficiency ratio, and adjusted efficiency ratio; and total stockholders’ equity in the case of tangible common equity, tangible common equity to tangible assets, tangible book value per common share, and return on average tangible common equity, appears below. The Company believes the adjusted measures are useful for investors and management to understand the effects of certain non-recurring noninterest items and provide additional perspective on the Company’s performance over time as well as comparison to the Company’s peers.

These non-GAAP disclosures have inherent limitations and are not audited. They should not be considered in isolation or as a substitute for the results reported in accordance with GAAP, nor are they necessarily comparable to non-GAAP performance measures that may be presented by other companies. Tax effected numbers included in these non-GAAP disclosures are based on estimated statutory rates and effective rates as appropriate.

Additional possible risks that could affect the Company 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

***The COVID-19 pandemic continues to create disruptions that affect our business, financial condition, liquidity, and results of operations.***

The extent to which COVID-19 will continue to affect business operations, financial condition, credit quality, and results of operations will depend on future developments that cannot be predicted, including the duration and scope of the pandemic. The direct or indirect impact on employees, customers, counterparties, and service providers, as well as other market participants, is likely to continue through 2022 as the world attempts to gain control over the virus and emerging variants. The impact that the virus continues to have on global markets, the economy, business restrictions, and employment is ongoing as a projected return to pre-pandemic operating conditions is unknown.

In the past year, the U.S. economy began to rebound from severe disruptions caused by the onset of the pandemic in March 2020. Economic conditions have begun to normalize with the availability of vaccines and treatments, increasing workforce employment and participation, the lessening of business and education restrictions, and demand for services beginning to return. The financial conditions of households and businesses was bolstered significantly by government stimulus, which contributed to the economic recovery but also brought about growing pains as evidenced by supply chain problems and rising prices. Although current economic conditions are more favorable than the prior year, the outlook for continued growth is characterized by elevated uncertainty with potential for unevenness across markets and sectors. Although household and business credit and liquidity is strong currently, further pandemic-related disruptions could result in increased risk of delinquencies, defaults, foreclosures, and losses on our loans; declines in assets under management, affecting wealth management revenues; negative impacts on regional economic conditions resulting in declines in local loan demand, liquidity of loan guarantors, loan collateral (particularly in real estate), loan originations, and deposit availability; and impacts on the implementation of our growth strategy. While the recovery this past year has been strong, the pace of growth in the U.S. and globally could decline as a result of rising inflation, higher interest rates, the pervasiveness of supply chain challenges across industries, and the persistence of the virus in variant forms.

Overall, we believe that the economic impact from COVID-19 will continue for some time and could have a material and adverse impact on our business and result in significant losses in our loan portfolio, all of which would adversely and materially impact our earnings and capital. Even after the COVID-19 pandemic has subsided, we may continue to experience materially adverse impacts to our business as a result of the global economic impact of the COVID-19 pandemic, including the availability of credit, adverse impacts on liquidity, and any recession that has occurred or may occur in the future. There are no comparable recent events that provide guidance as to the effect the spread of COVID-19 as a global pandemic may have, nor are there historical indicators to rely on in terms of how markets will react, and as a result, the ultimate impact of the pandemic is highly uncertain and subject to change.

***Conditions in the financial market and economic conditions, including conditions in the states in which it operates, generally may adversely affect the Company’s business.***

The Company’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.

The Company currently conducts its banking operations in downstate Illinois; suburban Chicago, Illinois; the St. Louis, Missouri metropolitan area; central Indiana; and southwest Florida. Economic conditions within Busey’s markets were adversely impacted by the COVID-19 pandemic, and although conditions have improved this past year, elevated unemployment, economic decline, on-going business restrictions and operational uncertainty continue to impact the markets overall, and in particular, certain industry sectors. The financial condition of the State of Illinois, in which the largest portion of the Company’s customer base resides, is characterized with low credit ratings, pension under-funding, budget deficits, and lower job growth rates than most of the country; furthermore, Illinois was one of three states in the country to lose population in the last decade. Notably, with the recent improvement in the state’s financial outlook, during the second half of 2021 Illinois received improved ratings from Moody’s Investor Service, S&P Global Ratings, and Fitch. The Company operates in markets with significant university and healthcare presence, which rely heavily on state and federal funding and contracts. Payment delays by the State of Illinois to its vendors and government-sponsored entities, as well as potential federal changes to healthcare laws, could affect the Company’s primary market areas, which could in turn adversely affect its financial condition and results of operations. The partial shutdown of colleges and universities across the state may also impact businesses heavily reliant on the colleges and universities for revenue generation. Recent downturns in local operating markets where banking operations occur could result in a decrease in demand for the Company’s products and services, an increase in loan delinquencies and defaults, high or increased levels of problem assets and foreclosures, and reduced wealth management fees resulting from lower asset values.

***Market volatility and changes in interest rates could have an adverse effect on the Company.***

Changes in interest rates could affect the level of assets and liabilities held on the Company’s balance sheet and the revenue that the Company earns from net interest income, as earnings and profitability depend significantly on our net interest income. Net interest income represents the difference between interest income and fees earned on interest-earning assets, such as loans and investment securities, and interest expense incurred on interest-bearing liabilities, such as deposits and borrowed funds. Interest rates are sensitive to many factors that are beyond the Company’s control, including general economic conditions and policies of various governmental and regulatory agencies, including the FOMC. Changes in monetary policy, including changes in interest rates, could influence not only the interest the Company receives on loans and investment securities and the amount of interest it pays on deposits and borrowings, but such changes could also affect the Company’s ability to originate loans and obtain deposits and the fair value of the Company’s financial assets and liabilities. In addition, a rise in interest rates could result in decreased demand for first mortgages as well as mortgage refinancing, activities which have historically contributed to a significant portion of the Company’s mortgage revenue. Furthermore, if the interest rates paid on deposits and other borrowings increase at a faster rate than the interest rates received on loans and investment securities, the Company’s net interest income, and therefore earnings, could be adversely affected. Earnings could also be adversely affected if the interest rates received on loans and other investments fall more quickly than the interest rates paid on deposits and other borrowings. Finally, when interest rates rise, competition for deposits often increases, which can lead to a change in the Company’s funding mix and cost of funding. Any substantial, unexpected, prolonged change in market interest rates could have a material adverse effect on the Company’s business, financial condition, and results of operations.

In March 2020, the Federal Reserve reduced the target federal funds rate and announced a $700.0 billion quantitative easing program in response to the expected economic downturn caused by the COVID-19 pandemic and reduced the interest it pays on excess reserves. The prolonged reduction in interest rates is likely to continue to have an adverse effect on our net interest income and margins and our profitability. The impact of the prolonged low rates will also continue to affect rate spreads and return on earning assets.

The Company’s wealth management business may also be negatively impacted by changes in general economic conditions and the conditions in the financial and securities markets, which could affect the values of assets under care. Management contracts generally provide for fees payable for wealth management services based on the market value of assets under care. Because most of the Company’s contracts provide for a fee based on market values of securities, declines in securities prices may have an adverse effect on the Company’s results of operations from this business. Market declines and reductions in the value of customers’ wealth management accounts, could also result in the loss of wealth management customers, including those who are also banking customers.

The Federal Reserve has signaled that it will begin to increase rates, taper its quantitative easing program, and reduce its balance sheet of bonds and other assets in 2022, but will do so with the goal of avoiding abrupt or unpredictable changes in economic or financial conditions so as not to disrupt the financial systems, also known as “shocks;” despite this, the impact of these changes cannot be certain. Vulnerabilities in the financial system can amplify the impact of an initial shock following rate increases, potentially leading to unintended volatility, as well to disruptions in the provision of financial services, such as clearing payments, the provision of liquidity, and the availability of credit. Furthermore, asset liquidation pressures can be amplified by liquidity mismatches and the leverage of certain nonbank financial intermediaries such as hedge funds. The financial crisis in March 2020 also demonstrated that pressures on dealer intermediation can limit the availability of liquidity during times of market stress. Given the interconnectedness of the global financial system, these vulnerabilities could impact the Company’s business operations and financial condition.

***The transition to an alternative reference rate could cause instability and have a negative effect on financial market conditions.***

LIBOR represents the interest rate at which banks offer to lend funds to one another in the international interbank market for short-term loans. On July 27, 2017, the United Kingdom Financial Conduct Authority announced that it will no longer persuade or compel banks to submit rates for the calculation of LIBOR rates after 2021. End dates for LIBOR have now been set, and U.S. Regulators have issued guidance as of October 2021 that urges market participants to address their existing LIBOR exposures and transition to robust and sustainable alternative rates by December 31, 2021. The Alternative Reference Rate Committee has proposed that SOFR is the rate that represents best practice as the alternative to U.S. dollar-LIBOR for use in derivatives and other financial contracts that are currently indexed to LIBOR, but has also advised market participants to conduct a comprehensive evaluation of any alternative reference rates being considered for use.

Contracts linked to LIBOR are vast in number and value, are intertwined with numerous financial products and services, and have diverse parties. Although the Company has actively worked to plan for the transition away from LIBOR, the transition is both complex and challenging and the downstream effect of unwinding or transitioning such contracts could cause instability and negatively impact financial markets and individual institutions. If the Company’s selected alternative rate is based on a small transaction volume, it could be susceptible to volatility and disruption during times of market stress. Furthermore, if the Company fails to properly address legacy contracts by adding robust fallback positions, it will be exposed to interest rate risks and potential loss of yields. Finally, if the Company or other market participants fail to properly plan to implement alternative rates other than LIBOR, it could have an adverse effect on the Company and the financial system as a whole. In 2021, we began the transition to SOFR and other interest rate benchmarks in anticipation of the cessation of the publication of LIBOR.

***Continued elevated levels of inflation could adversely impact our business and results of operations.***

The U.S. has recently experienced elevated levels of inflation, with the consumer price index climbing approximately 7.0% in 2021. Continued levels of inflation could have complex effects on our business and results of operations, some of which could be materially adverse. For example, if interest rates were to rise in response to, or as a result of, elevated levels of inflation, the value of our securities portfolio would be negatively impacted. In addition, while we generally expect any inflation-related increases in our interest expense to be offset by increases in our interest revenue, inflation-driven increases in our levels of non-interest expense could negatively impact our results of operations. Continued elevated levels of inflation could also cause increased volatility and uncertainty in the business environment, which could adversely affect loan demand and our clients’ ability to repay indebtedness. It is also possible that governmental responses to the current inflation environment could adversely affect our business, such as changes to monetary and fiscal policy that are too strict, or the imposition or threatened imposition of price controls. The duration and severity of the current inflationary period cannot be estimated with precision.

***Labor shortages and failure to attract and retain qualified employees could negatively impact our business, results of operations and financial condition.***

A number of factors may adversely affect the labor force available to us or increase labor costs, including high employment levels, decreased labor force size and participation rates as a result of the COVID-19 pandemic, expanded unemployment benefits offered in response to the ongoing COVID-19 pandemic, and other government actions. Although we have not experienced any material labor shortage to date, we have recently observed an overall tightening and increasingly competitive local labor market. A sustained labor shortage or increased turnover rates within our employee base could lead to increased costs, such as increased compensation expense to attract and retain employees.

In addition, if we are unable to hire and retain employees capable of performing at a high-level, or if mitigation measures we may take to respond to a decrease in labor availability have unintended negative effects, our business could be adversely affected. An overall labor shortage, lack of skilled labor, increased turnover, or labor inflation, caused by COVID-19 or as a result of general macroeconomic factors, could have a material adverse impact on our operations, results of operations, liquidity, or cash flows.

### Regulatory and Legal Risks

***Legislative and regulatory actions taken now or in the future may increase our costs and impact our business, governance structure, financial condition, or results of operations.***

Laws, regulations, rules, policies, and regulatory interpretations governing the Company continue to evolve and will likely continue to change over time as Congress and various regulatory agencies react to adverse economic conditions or other matters. The 2021 change of the presidential administration and Congressional control has prompted new or revitalized financial services regulation. The extent and scope of potential financial regulations is hard to predict, but continued changes are expected to occur as leadership and priorities in various regulatory bodies shifts.

Implementation of current or proposed regulatory or legislative changes to laws applicable to the financial industry may impact the profitability of the Company’s business activities and may change certain business practices, including the ability to offer new products, obtain financing, attract deposits, make loans, achieve satisfactory interest spreads, and enter into acquisition and merger agreements, and could expose the Company to additional expense, including increased compliance costs. Appointments to the primary banking regulatory agencies affect monetary policy and interest rates, and changes in fiscal policy could affect broader patterns of trade and economic growth. Executive orders, future legislation, regulation, and government policy could affect the banking industry as a whole, including our business and results of operations, in ways that are difficult to predict. In addition, our results of operations also could be adversely affected by changes in the way in which existing statutes and regulations are interpreted or applied by courts and government agencies.

These rule and regulatory changes may also require the Company to invest significant management attention and resources so as to make necessary changes to operations in order to comply. In addition to the expense and uncertainty related to 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 the Company were the subject of an enforcement action, it could have an adverse impact on the Company.

***As the Company continues to grow in asset size and complexity, regulatory expectations and scrutiny will likely increase and could have a potential impact on the Company’s operations and business.***

The Company has grown steadily over the past several years, increasing 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 $10.0 billion in assets. The Company anticipated crossing the $10.0 billion threshold for some time, and it did so in 2020.

On November 20, 2020, the federal bank regulatory agencies announced an Interim Final Rule, providing temporary relief for certain community banking organizations related to certain regulations and reporting requirements as a result of growth in size from the COVID-19 response. The Company has been provided temporary relief under this rule with respect to the interchange revenue impacts of the Durbin Amendment. The Company did not reduce its asset size back below the $10.0 billion threshold and has instead increased assets to $12.9 billion as of December 31, 2021. The relief expired December 31, 2021, and as a result, regulatory expectations, scrutiny, and reporting requirements are expected to continue to increase, and may affect the Company’s operations and strategies.

***Laws impacting cannabis-related businesses in Illinois and other states may have an impact on the Company’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. It is Busey Bank’s current practice to avoid knowingly providing banking products or services to entities or individuals that: (i) directly or indirectly manufacture, distribute, or dispense marijuana or hemp products, or those with a significant financial interest in such entities; or (ii) 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 law legalizing cannabis use, along with shifts in Missouri and 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 the Company 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 the Company.

### Credit and Lending Risks

***Heightened credit risk associated with lending activities may result in insufficient loan loss provisions, which could have material adverse effect on the Company’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. The Company 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. However, while such procedures help reduce risks, they cannot be expected to completely eliminate the Company’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 loan losses. When economic conditions decline or significant shifts in demand change, as they have during the COVID-19 pandemic, increases in non-performing loans, charge-offs, and delinquencies become more likely.

The Company estimates and establishes reserves for credit losses and maintains them at a level considered adequate by management to absorb probable credit losses based on a continual analysis of the Company’s portfolio and market environment. These reserves represent the Company’s estimate of probable losses in the portfolio at each balance sheet date and are based upon other relevant information available.

In 2016, the FASB published CECL, which requires recording loss estimates for the life of the instrument for loans, a change from the 40-year standard in which losses are recorded under the “incurred loss” concept. Adoption of CECL in 2020 resulted in additional reserves being set aside to protect against future credit losses. Although management believes the reserves are 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 the Company’s results of operations and financial condition and could result in further losses in the future.***

The Company’s non-performing assets adversely affect its net income in various ways. While the Company pays interest expense to fund non-performing assets, it does not record interest income on non-accrual loans or other real estate owned, thereby adversely affecting its income and returns on assets and equity. In addition, loan administration costs increase, and the Company’s efficiency ratio is adversely affected. When the Company takes collateral in foreclosures and similar proceedings, it is required to mark the collateral to its then-fair market value, which, when compared to the outstanding balance of the loan, may result in a loss. Non-performing loans and other real estate owned also increase the Company’s risk profile and the capital its regulators believe is appropriate in light of such risks. The resolution of non-performing assets requires significant time commitments from management, which can be detrimental to the performance of their other responsibilities. Although it is hard to fully predict the affect the COVID-19 pandemic will have on the Company’s asset quality, it’s performance may be adversely affected if it experiences increases in non-performing loans and non-performing assets in the future.

Federal regulatory agencies, in consultation with FASB, issued updated guidance on March 22, 2020, for classifying loans as TDRs, which allowed banks to modify loans of customers stressed by COVID-19 without having to classify the loan as a TDR. While this updated guidance provided temporary relief for both borrowers and banks, these loan modifications may not be sufficient to keep the assets the Company holds from deteriorating if the duration of the pandemic is prolonged.

***Concentrations of credit and market risk could increase the potential for significant losses.***

The Company 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 the Company’s loan portfolio is made up of commercial, commercial real estate, and retail real estate loans. Thus, deterioration in economic conditions or real estate values could result in higher credit costs and losses to the Company. The global pandemic in 2020 significantly impacted both global and domestic markets and economies as shutdowns and restrictions to prevent the spread of the virus affected several different business sectors. Although many business sectors rebounded as restrictions lifted during 2021, the full impact of the shutdowns and restrictions, along with the effect of changing demands resulting from the pandemic cannot be known at this time. The Company has taken additional steps to quantify the potential risk and impacted industries that are likely to experience stress to cash flows and pose higher potential default risk.

The Company’s commercial loans are primarily made 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 the Company 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. The 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 the Company’s financial condition and results of operations.

A significant portion of the Company’s loans are collateralized by real estate. 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. Adverse changes in the economy affecting real estate values and liquidity generally, and in markets in which the Company has banking operations, could significantly impair the value of property pledged as collateral on loans and affect the Company’s ability to sell the collateral upon foreclosure without a loss or additional losses. 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 the Company 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 borrower to sell or lease the property, rather than the ability of the borrower or guarantor to repay principal and interest. If the Company’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 the Company 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, the Company 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 the Company’s investment portfolio may increase the potential for loss.***

The Company’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 the Company’s financial condition and results of operations.

### Capital and Liquidity Risks

***The Company 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.***

First Busey and Busey Bank must meet regulatory capital requirements and maintain sufficient liquidity. The Company’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 the Company’s control, and on its financial condition and performance. Accordingly, the Company cannot guarantee that it will be able to raise additional capital if needed or on terms acceptable to the Company. If it fails to meet these capital and other regulatory requirements, its financial condition, liquidity, and results of operations would be materially and adversely affected.

The Company’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 the Company 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 the Company’s business, financial condition, and results of operations.***

Liquidity is essential to the Company’s business. An inability to raise funds through deposits, borrowings, the sale of loans, and other sources could have a substantial negative effect on liquidity. The Company’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 the Company’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.

During periods of economic turmoil, the financial services industry and the credit markets generally may be materially and adversely affected by significant declines in asset values and depressed levels of liquidity. These and other factors could negatively affect the Company’s ability to engage in routine funding and other transactions with other financial institutions and lead to market-wide liquidity problems, loss of depositor, creditor, and counterparty confidence, which could lead to losses or defaults by the Company or by other institutions. Although the Company is not currently experiencing liquidity stress, pandemic-related market conditions remain uncertain. Any decline in available funding and/or capital could adversely impact the Company’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.

***The soundness of other financial institutions could negatively affect the Company.***

As indicated in the “*Item 1A. Risk Factors—Economic and Market Risks”* section above, the Company’s ability to engage in routine funding and other transactions could be negatively affected by the actions and commercial soundness of other financial institutions. Financial services institutions are interrelated as a result of trading, clearing, counterparty, or other relationships. Defaults by, or even rumors or questions about, one or more financial services institutions, or the financial services industry generally, have led to market-wide liquidity problems and losses of depositor, creditor, and counterparty confidence and could lead to losses or defaults by the Company or by other institutions. The Company could experience growth as a result of the difficulties or failures of other banks or government-sponsored financial institutions, which would increase its funding needs.

### 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.

***The Company faces strong competition from financial service companies and other companies that offer banking and wealth management services, which could harm its business.***

The Company currently conducts its banking operations in downstate Illinois; 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 the Company’s market areas. These competitors include national banks, regional banks, and other community banks. The Company 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 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 the Company’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 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 the Company’s markets may result in reduced loans, deposits, and commissions and brokers’ fees, as well as reduced net interest margin and profitability. Ultimately, the Company may not be able to compete successfully against current and future competitors. If the Company 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.

***Rapid speed of disruptive innovations enabled by new and emerging technologies and/or other market forces may outpace the Company’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. 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, 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. 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 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 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. The Company 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 and assumptions and methods used by management, which, if incorrect, could cause unexpected losses in the future.***

The Company’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 the Company’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 the Company’s analysis does not indicate impairments exist, the Company is required to perform additional impairment assessments on at least an annual basis, and perhaps more frequently, which could result in further 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.

***The Company 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 the Company’s Financial Statements. These changes are beyond the Company’s control, can be difficult to predict, and could materially impact how the Company reports its financial condition and results of operations. Changes in these standards are continuously occurring and the implementation of such changes could have a material adverse effect on the Company’s financial condition and results of operations.

***The Company 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 the Company’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 the Company’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, the Company estimates future taxable income based on management forecasts and tax planning strategies that may be available to us. While the Company has determined that no valuation allowance is currently required for any deferred tax assets, if future events differ significantly from our current forecasts, it 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, the Company’s investments in certain tax-advantaged projects may not generate returns as anticipated and may have an adverse impact on the Company’s financial results. The Company invests in certain tax-advantaged projects promoting affordable housing, community development and other community revitalization projects. The Company’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. The Company 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 able to be realized. The possible inability to realize these tax credit and other tax benefits can have a negative impact on the Company’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

***The Company’s framework for managing risks may not be effective in mitigating risk and loss.***

The Company’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, the Company’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, the Company could suffer unexpected losses and could be materially adversely affected.

***The Company 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 the Company’s operations.***

Communications and information systems are essential to conduct the Company’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 the Company 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, the Company outsources certain processing functions to third-party providers. If third-party providers encounter difficulties or if the Company has difficulty in communicating with them, the ability to adequately process and account for customer transactions may be affected and business operations may be adversely impacted. If third-party providers are unable to meet service expectations, experience system or processing failure, or incur disruptions affecting operations, results could adversely impact the Company. While the Company follows certain due diligence procedures in reviewing and vetting its third-parties, it cannot control their actions.

Although the Company has procedures in place to prevent or limit the effects of any of these potential problems and intends to continue to implement security technology and establish operational procedures to prevent such occurrences, technology-related disruptions, failures, and cybersecurity risks are a constant threat, both for the Company and for the third-parties it works with. Therefore, it cannot guarantee that these measures will be successful. Any failure, interruption in, or breach in security of, its computer systems and network infrastructure, as well as those of its customers engaging in internet banking activities or electronic funds transfers, could have a material adverse effect on its financial condition and results of operations.

Similarly, the Company 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 the Company’s control. The Company 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. In addition, the Company’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 the Company’s systems could disrupt its businesses, result in the disclosure of confidential information, damage its reputation, and create significant financial and legal exposure for the Company.***

Although the Company 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. In the past year, a myriad of industries and institutions have reported breaches in the security of their websites or other systems, some of which have involved sophisticated and targeted attacks 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 taken advantage of the pandemic to create campaigns to leverage individuals fears and uncertainties as well as capitalize on the increased number of transactions occurring on digital channels. The 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 the Company 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, known as “supply chain risk,” to anticipate, detect, or adequately mitigate, breaches of security 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.

The Company 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 the Company’s customers through various third-parties, including merchant acquiring banks, payment processors, payment card networks, and its processors. Cyber-attacks or other breaches, whether affecting the Company 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 the Company’s business.

Penetration or circumvention of the Company’s security systems could result in serious negative consequences for the Company, including significant disruption of the Company’s operations, misappropriation of confidential information of the Company or that of its customers or employees, or damage to computers or systems of the Company and those of its customers and counterparties. Such events could result in violations of applicable privacy and other laws, financial loss to the Company or its customers, loss of confidence in the Company’s security measures, customer dissatisfaction, significant litigation exposure and harm to the Company’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 the Company’s significant investment in security resources and its continued efforts to prevent or limit the effects of potential threats, it is possible that the Company 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 the Company’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. The Company 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 the Company to certain fraud risks associated with the compromise of their computing systems or accounts, as well.

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 the Company’s business, results of operations, and financial condition.

***The Company’s ability to attract and retain management and key personnel may affect future growth and earnings and legislation imposing new compensation restrictions could adversely affect its ability to do so.***

Much of the Company’s success and growth has been influenced by its ability to attract and retain management experienced in banking and financial services and familiar with the communities in its market areas. The Company’s ability to retain executive officers, current management teams, lending and retail banking officers, and administrative staff of its subsidiaries continues to be important to the successful implementation of its strategy. In addition, the Company’s ability to retain key personnel at acquired financial institutions is vitally important to the Company’s strategy to grow through mergers and acquisitions. Also critical is the Company’s ability to attract and retain diverse and qualified staff with the appropriate level of experience and knowledge about its market areas so as to implement its community-based operating strategy. Recent changes in labor market conditions have contributed to heightened levels of employee attrition and increased competition for talent, which has in turn driven wage rates higher and may contribute to an increase in operating expenses. 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 the Company’s business, financial condition, and results of operation.

***Damage resulting from negative publicity could harm the Company’s reputation and adversely impact its business and financial condition.***

The Company’s ability to attract and maintain 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 the Company’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 the Company’s business, financial condition, and results of operations.

***Climate change or other adverse external events could significantly impact the Company’s business.***

Severe weather, natural disasters, geopolitical risks and acts of terrorism or war, widespread disease or pandemics, as is currently being experienced, and other adverse external events could have a significant impact on the Company’s ability to conduct business. Climate change, in particular, presents multi‐faceted risks including: operational risk from the physical effects of climate events on our and our customers’ facilities and other assets; credit risk from borrowers with significant exposure to climate risk; and reputational risk from stakeholder concerns about our practices related to climate change.

Climate change exposes the Company to physical risk as its effects may lead to more frequent shifts in weather patterns and more extreme weather events that could damage, destroy, or otherwise impact the value or productivity of our properties and other assets; reduce the availability of insurance to cover losses; and/or disrupt our operations through prolonged outages. Such events and long‐term shifts may also have a significant impact on our customers, which could amplify credit risk by diminishing borrowers’ repayment capacity or collateral values, and other businesses and counterparties with whom we transact, which could have a broader impact on the economy, supply chains, and distribution networks.

Furthermore, banking regulators and other supervisory authorities, investors and other stakeholders have increasingly viewed financial institutions as important in helping to address the risks related to climate change both directly and with respect to their customers, which may result in financial institutions coming under increased pressure regarding the disclosure and management of their climate risks and related lending and investment activities. Given that climate change could impose systemic risks upon the financial sector, either via disruptions in economic activity resulting from the physical impacts of climate change or changes in policies as the economy transitions to a less carbon‐intensive environment, we face regulatory risk of increasing focus on our resilience to climate‐related risks, including in the context of stress testing for various climate stress scenarios. Ongoing legislative or regulatory changes regarding climate risk management and practices may result in higher regulatory, compliance, credit and reputational risks and costs.

### Impact of COVID-19

Although the progression of the COVID-19 pandemic in the U.S. has impacted First Busey’s results of operations, we continue to navigate the economic environment caused by COVID-19 effectively and prudently and remain resolute in our focus on serving our customers, communities, and associates while protecting our balance sheet. We remain vigilant, given that negative impacts of COVID-19, such as further margin compression and a deterioration in asset quality, could impact future quarters.

### Effects on Our Market Areas

Our commercial and consumer banking products and services are delivered in Illinois, Missouri, Florida, and Indiana. Each state has taken different steps to reopen after COVID-19 thrust the country into lockdown starting in March 2020, and these efforts are subject to changes and delays based on case monitoring in each state.

### Policy and Regulatory Developments

Federal, state, and local governments, and regulatory authorities have enacted and issued a range of policy responses to the COVID-19 pandemic. Regulatory actions taken during 2021 include the following:

- On March 11, 2021, President Biden signed the American Rescue Plan Act of 2021, a $1.9 trillion relief package providing a third round of Economic Impact Payments to millions of eligible Americans, expanding unemployment benefits and tax credits, providing additional assistance to small businesses, and creating a $10 billion homeowner assistance fund. This fund can be used toward delinquent mortgage payments and is intended to minimize foreclosures in the coming months. An additional $7.25 billion in PPP funding was provided, and eligibility criteria was expanded to include some non-profit organizations.
- On March 30, 2021, President Biden signed the PPP Extension Act of 2021, which extended the PPP application deadline to May 31, 2021, or until funding was exhausted. PPP funding for loans originated by lenders other than community financial institutions was exhausted as of May 6, 2021. All PPP funding was exhausted as of May 28, 2021.

### Our Response

We have taken, and continue to take, numerous steps in response to the COVID-19 pandemic, including the following:

- First Busey offered a Financial Relief Program to qualifying customers designed to alleviate some of the financial hardships that they faced as a result of COVID-19. This program offered solutions for all types of customers—including retail, personal loan, and mortgage—as well as commercial clients and small businesses. The program included options for loan payment deferrals as well as certain fee waivers. As of December 31, 2021, we had 32 commercial loans remaining on interest-only payment deferrals representing $128.7 million in loans. In addition, as of December 31, 2021, we had two retail loans on payment deferrals representing $0.1 million.
- First Busey has served as a bridge for the PPP, actively helping existing and new business clients sign up for this important financial resource. The following table summarizes our PPP loans as of December 31, 2021 *(dollars in thousand):*

| ​ ​ ​ | ​ ​ | ​ ​ CARES Act | ​ ​ | ​ ​ Economic Aid Act | ​ ​ | ​ ​ PPP Loan Totals |
| --- | --- | --- | --- | --- | --- | --- |

### Critical Accounting Estimates

First 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 First 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:

### Fair Value of Debt Securities Available for Sale

The 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. The use of different judgments and estimates to determine the fair value of securities could result in a different fair value estimate.

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, 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. The impairment is recognized by establishing an allowance through 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 820 as “the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date.”

The 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 326. However, the offset to record the allowance at the date of acquisition on acquired loans 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

First 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

First 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 First 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 allowance, management relies predominantly on a disciplined credit review and approval process that extends to the full range of First Busey’s credit exposure. The ACL must be determined on a collective (pool) basis when similar risk characteristics exists. 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 allowance. A provision for credit losses is charged to current expense and acts to replenish the ACL in order to maintain the allowance at a level that management deems adequate. Determining the allowance 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.

On May 31, 2021, First Busey completed its acquisition of CAC, the holding company for GSB. GSB was operated as a separate banking subsidiary from June 1, 2021, until August 14, 2021, when it was merged with and into Busey Bank. At that time GSB’s seven banking centers became banking centers of Busey Bank. When we completed the GSB acquisition, we reset the baseline for the future financial performance of First Busey in a multitude of positive ways. With GSB now merged and integrated, we expect to see the full contribution of synergies of GSB reflected in our financial performance in the years ahead.

On November 19, 2021, 17 banking centers, two of which were previously GSB banking centers, were closed and consolidated, as part of the Company’s efforts to ensure a balance between its physical banking center network and robust digital banking services while also optimizing operating efficiency. Following the completion of these banking center closures and consolidations, the Company continues to operate a total of 58 banking centers across its markets.

First Busey views certain non-operating items, including acquisition-related and restructuring charges, as adjustments to net income reported under GAAP. Non-operating pretax adjustments for 2021 included $13.6 million of expenses related to acquisitions and $3.7 million of expenses related to other restructuring costs. The reconciliation of non-GAAP measures (including pre-provision net revenue, adjusted pre-provision net revenue, pre-provision net revenue to average assets, adjusted pre-provision net revenue to average assets, adjusted net income, adjusted earnings per share, adjusted return on average assets, adjusted net interest margin, adjusted noninterest expense, efficiency ratio, adjusted efficiency ratio, tangible common equity, tangible common equity to tangible assets, tangible book value per share, and return on average tangible common equity), which First Busey believes facilitates the assessment of its financial results and peer comparability, is included in tabular form in this Annual Report. See “*Item 1. Business—Non-GAAP Financial Information.”*

Combined, revenues from wealth management fees and payment technology solutions activities represented 53.8% of First Busey’s noninterest income in 2021, providing a balance to spread-based revenue from traditional banking activities. Further, noninterest income, excluding net securities gains (losses) represented 32.4% of total revenue for the year ended December 31, 2021.

### Results of Operation — Three Years Ended December 31, 2021

### Net Interest Income

Net interest income is the difference between interest income and fees earned on earning assets and interest expense incurred on interest-bearing liabilities. Interest rate levels and volume fluctuations within earning assets and interest-bearing liabilities impact net interest income. Net interest margin is tax-equivalent net interest income as a percent of average earning assets.

Certain assets with tax favorable treatment are evaluated on a tax-equivalent basis. Tax-equivalent basis assumes 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.

The following tables *(dollars in thousands)* show our Consolidated Average Balance Sheets, detailing the major categories of assets and liabilities, the interest income earned on interest-earning assets, the interest expense paid for the interest-bearing liabilities, and the related interest rates for the periods shown. The tables also show, for the periods indicated, a summary of the changes in interest earned and interest expense resulting from changes in volume and rates for the major components of interest-earning assets and interest-bearing liabilities. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately, based on changes due to rate and changes due to volume. All average information is provided on a daily average basis.

(1) Assuming a federal income tax rate of 21.0%.

(2) Net interest income expressed as a percentage of average earning assets, stated on a tax-equivalent basis.

The Consolidated Average Balance Sheets and interest rates were impacted in 2021 and 2020 by numerous factors surrounding COVID-19. Further, the 2021 Consolidated Average Balance Sheet was impacted by the CAC acquisition. The FOMC rate cuts during the first quarter of 2020 have contributed to the decline in net interest margin, as assets, in particular commercial loans, repriced more quickly and to a greater extent than liabilities. Net interest margin has also been negatively impacted by existing loan amortization and paydowns at higher rates than new loan production, the sizeable balance of lower-yielding PPP loans, significant growth in the Company’s liquidity position, and the issuance of debt. Those impacts were partially offset by the Company’s efforts to lower deposit funding costs as well as the fees recognized on PPP loans.

First Busey remains substantially core deposit funded, with robust liquidity and significant market share in the communities we serve. As of December 31, 2021, our loan to deposit ratio was 66.8% and core deposits represented 98.7% of total deposits outstanding (excluding time deposits with balances greater than $250,000).

Net interest spread, which represents the difference between the average rate earned on earning assets and the average rate paid on interest-bearing liabilities, was 2.36% in 2021 compared to 2.83% in 2020 and 3.10% in 2019, each on a tax equivalent basis.

Annualized net interest margins for the quarterly periods indicated were as follows:

| ​ ​ | ​ ​ 2021 | ​ ​ ​ ​ 2020 | ​ ​ ​ ​ 2019 ​ |
| --- | ---: | ---: | ---: |
| First Quarter | 2.72% | 3.20% | 3.46% |
| Second Quarter | 2.50% | 3.03% | 3.43% |
| Third Quarter | 2.41% | 2.86% | 3.35% |
| Fourth Quarter | 2.36% | 3.06% | 3.27% |

Management attempts to mitigate the effects of an unpredictable interest-rate environment through effective portfolio management, prudent loan underwriting and operational efficiencies.

| Total noninterest income | ​ | $118,265 | ​ | $116,415 | ​ | $1,850 | ​ | ​ | 1.6% |

Total noninterest income increased 12.3% to $132.8 million for the year ended December 31, 2021, compared to $118.3 million for the year ended December 31, 2020. Revenues from wealth management fees and payment technology solutions represented 53.8% for the year ended December 31, 2021, compared to 49.5% for the year ended December 31, 2020. Payment technology solutions revenue relates to our payment processing company, FirsTech.

Wealth management fees increased 23.7% to $53.1 million in 2021, compared to $42.9 million in 2020. Assets under care increased 24.5% to $12.7 billion as of December 31, 2021, compared to $10.2 billion at December 31, 2020. The increase in assets under care includes $1.2 billion related to assets obtained in the acquisition of CAC, with the remaining $1.3 million related to organic and market related growth.

Fees for customer services increased 12.7% to $35.6 million in 2021, compared to $31.6 million in 2020. Fees for customer services have been impacted since early 2020 by changing customer behaviors resulting from COVID-19, and government stimulus programs, and continue to rebound with improving economic conditions and customer activity levels.

Payment technology solutions revenue increased 17.4% to $18.3 million in 2021, compared to $15.6 million in 2020. Fluctuations in payment technology solutions revenue were primarily the result of increased payment and volume activity as well as growth in customers served by FirsTech. FirsTech operations add important diversity to our revenue stream while widening our array of service offerings to larger commercial clients both within our footprint and nationally. We are currently making strategic investments in FirsTech to further enhance future growth including further upgrades to the product and engineering teams to build an API first cloud-based platform to provide for fully integrated payment capabilities as well as the continued development of our BaaS platform.

Mortgage revenue decreased 44.5% to $7.2 million in 2021, compared to $13.0 million in 2020. Sold-loan mortgage volume declined in 2021 compared to 2020 due to a higher share of portfolio loan production in 2021.

Income on bank owned life insurance decreased 4.0% to $5.2 million in 2021, compared to $5.4 million in 2020, as a result of a decrease in earnings on the cash surrender value of the policies.

Other income increased 23.2% to $10.3 million in 2021 compared to $8.4 million in 2020. Other income variances are primarily driven by fluctuations in income generated from swap origination fees, commercial loan sales gains, and gains and losses on fixed asset disposal.

Total noninterest expense increased to $261.8 million in 2021, compared to $234.2 million in 2020. Non-operating acquisition and other restructuring increased to $17.4 million in 2021, compared to $10.7 million in 2020, contributing $6.7 million of the total $27.6 million increase in noninterest expense. In addition, GSB’s results of operations were included in First Busey’s consolidated results of operations beginning June 1, 2021. We remain focused on expense discipline and have begun to realize synergies from the GSB merger and Personal Banking Transformation Plan, which resulted in the consolidation of 17 branches across our various markets.

Salaries, wages, and employee benefits increased to $145.3 million in 2021, compared to $126.7 million in 2020. Non-operating expenses contributed $5.3 million of the total $18.6 million increase. Salaries, wages, and employee benefit expenses were also impacted by increases in full-time equivalent employees since June 1, 2021, related to the CAC acquisition, and we began to see synergies in late August after GSB was merged into Busey Bank. We had a total of 1,463 full-time equivalents at December 31, 2021, compared to 1,346 at December 31, 2020. Current labor market trends reflect a shrinking labor supply, while job growth reflects increasing demand for a skilled workforce, putting further upward pressure on salaries, wages, and employee benefits.

Data processing expense increased to $21.9 million in 2021, compared to $16.4 million in 2020. Non-operating expenses comprised $3.6 million of the total $5.4 million increase. Data processing for 2021 also includes data processing related to CAC from June 1, 2021, until GSB merged with Busey Bank on August 14, 2021.

Combined, net occupancy expense of premises and furniture and equipment expenses decreased to $26.6 million in 2021, compared to $27.2 million in 2020. GSB added 7 branches on June 1, 2021. We closed 12 banking centers in October 2020, and completed the previously announced closure and consolidation of 17 banking centers, two of which were formerly GSB banking centers, in November 2021. The full benefit of reduction in expenses related to these locations will be realized in future periods as those properties are divested.

Professional fees decreased to $7.5 million in 2021, compared to $8.4 million in 2020, as a result of decreases in legal fees, audit and accounting fees, payroll service costs, and consulting fees. Excluding non-operating expenses, professional fees decreased from $7.8 million in 2020 to $5.9 million in 2021.

Amortization of intangible assets increased to $11.3 million in 2021, compared to $10.0 million in 2020, as a result of increases in intangible asset balances from the acquisition of CAC.

Interchange expense increased to $5.8 million in 2021, compared to $4.8 million in 2020, as a result of increased payment and volume activity at FirsTech.

Other expense increased to $43.3 million in 2021, compared to $40.7 million in 2020. Variances occurred across multiple expense categories, including NMTC amortization, regulatory expenses, marketing, business development, recruiting and onboarding, director compensation, and card service fees, partially offset by lower MSR valuation impairment, lower fixed asset impairment, and releases in the provision for unfunded commitments.

### Efficiency Ratio (1)

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. The efficiency ratio was 62.2% in 2021, compared to 55.7% in 2020. Operating costs have been influenced by acquisition expenses and other restructuring costs, and the adjusted efficiency ratio1 was 57.9% for the year ended December 31, 2021, compared to 53.0% for the year ended December 31, 2020.

### Income Taxes

The effective income tax rate, or income taxes divided by income before taxes, was 21.3%, 21.7%, and 23.4% for the years ended December 31, 2021, 2020, and 2019, respectively. The decrease in the effective tax rate was driven by an increase in tax exempt income, such as municipal bond interest and bank owned life insurance income, combined with the benefits received from various investments in federal and state tax credits, including an Illinois NMTC. We continue to monitor evolving federal and state tax legislation and its potential impact on operations on an ongoing basis. As of December 31, 2021, we were not under examination by any tax authority.

The primary purposes of our investment securities portfolio are to provide a source of liquidity; to provide collateral for pledging purposes against public monies and repurchase agreements; to serve as a tool for interest rate risk positioning; and to provide a source of earnings by deploying funds which are not needed to fulfill loan demand, deposit redemptions, or other liquidity purposes. Pledged securities totaled $708.9 million, or 17.8% of total securities, at December 31, 2021, and $628.0 million, or 27.8% of total securities, at December 31, 2020.

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, and overall portfolio allocation. As of December 31, 2021, we did not have any non-U.S. Treasury securities or obligations of U.S. government corporations and agencies issued securities that exceeded 10% of our total stockholders’ equity.

### Portfolio Loans

We believe that making sound and profitable loans is a necessary and desirable means of employing funds available for investment. First 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. GSB’s policies were similar in nature to Busey Bank’s policies, and we are migrating the legacy GSB portfolio toward Busey Bank’s policies. 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 residential mortgage loans originated for sale in the secondary market or loans 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. In anticipation of the potential risks associated with COVID-19, we took actions starting in early March 2020 to escalate the monitoring of susceptible industry sectors within our 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 and its subsidiaries, are reviewed for compliance with regulatory guidelines.

First 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 the 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 can be summarized into five primary areas: commercial loans, commercial real estate loans, real estate construction loans, 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 historical and projected cash flow of the underlying borrower and secondarily on the underlying assets pledged as collateral by the borrower. Cash flows of the underlying 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 2021, we sold the majority of our newly originated 30-year fixed rate retail real estate loans to secondary market purchasers, while retaining a larger percentage of the 15-year fixed rate loans in our portfolio. 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 the FICO credit scoring, and information as to the underlying collateral. In 2021, associated with the CAC acquisition and purchased participations, retail other loans now also include whole-life loans which are secured by the cash value of life insurance policies. Repayment of retail other loans is expected from the cash flow of the borrower.

As of December 31, 2021, portfolio loan balances included balances acquired in the CAC acquisition. The Company generated $460.7 million in core loan growth, excluding PPP loans, over the last three quarters of 2021. Commercial balances – consisting of commercial, commercial real estate and real estate construction loans – excluding PPP loans, increased by $452.2 million, or 9.2%, during the year ended December 31, 2021. Retail real estate and retail other loans increased by $294.0 million, or 20.3%, during the year ended December 31, 2021. PPP loans decreased $371.4 million during the year ended December 31, 2021, to $75.0 million.

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, 2021, 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.

### Provision for Credit Losses

The ACL is a significant estimate in our Consolidated Balance Sheet, 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 should be 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. We recorded a provision release of $15.1 million for the year ended December 31, 2021, reflecting improvements in macroeconomic conditions and asset quality, compared to a provision expense of $38.8 million and $10.4 million for the years ended December 31, 2020, and 2019, respectively.

### Non-performing Loans and Non-performing Assets

Loans are considered past due if the required principal and 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 the 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.

Credit quality continues to be exceptionally strong. Total non-performing assets were $21.3 million at December 31, 2021, compared to $28.9 million at December 31, 2020. Asset quality metrics remain dependent upon market-specific economic conditions, and specific measures may fluctuate from period to period. Continued disciplined credit management resulted in non-performing loans as a percentage of portfolio loans of 0.23% at December 31, 2021, compared with 0.36% at December 31, 2020. If economic conditions were to deteriorate, we would expect the credit quality of our loan portfolio to decline and loan defaults to increase. Allowance coverage of non-performing loans increased to 521.5% at December 31, 2021, compared to 415.8% at December 31, 2020.

Classified assets, which includes non-performing assets and substandard loans, declined to $91.8 million at December 31, 2021, compared to $97.8 million at December 31, 2020. The ratio of classified assets to Busey Bank Tier 1 capital and ACL declined to 6.9% at December 31, 2021, from 8.5% at December 31, 2020.

### 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 increased to $70.5 million at December 31, 2021, compared to $68.8 million at December 31, 2020. 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, 2021, management identified no other loans that represent or result from trends or uncertainties which would be expected to materially impact future operating results, liquidity, or capital resources.

### Deposits

We focus on deepening our relationship with customers to foster core deposit growth, allowing us to reduce our reliance on wholesale funding. Our 2021 deposit balances were impacted by the retention of PPP loan funding in customer deposit accounts, the impacts of economic stimulus, and other core deposit growth. Core deposits include non-brokered transaction accounts, money market deposit accounts, and time deposits of $250,000 or less. Time deposits as a percentage of total deposits decreased to 8.7% as of December 31, 2021, compared to 12.9% as of December 31, 2020. As time deposits mature, we are actively engaging our customers to renew at current market rates.

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. The following table summarizes the uninsured portion of time deposits by maturity date *(dollars in thousands):*

| ​ ​ ​ Uninsured time deposits by schedule of maturities | ​ ​ ​ | ​ ​ As of December 31, 2021 ​ ​ |
| --- | --- | ---: |
| 3 months or less |  | $24,946 |
| Over 3 months through 6 months | ​ | 23,108 |
| Over 6 months through 12 months | ​ | 34,362 |
| Thereafter | ​ | 47,396 |
| Uninsured time deposits | ​ | $129,812 |

### Borrowings

Securities sold under agreements to repurchase, which are classified as secured borrowings, generally mature daily. Short-term borrowings include FHLB advances which mature in less than one year from the date of origination, and the current portion of long-term debt due within 12 months.

On May 28, 2021, First Busey entered into a Second Amended and Restated Credit Agreement, pursuant to which we have access to (i) a $40.0 million revolving line of credit with a termination date of April 30, 2022, and (ii) a $60.0 million term loan with a maturity date of May 31, 2026. The loans have an annual interest rate of 1.75% plus the 1-month LIBOR rate. 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 and for general corporate purposes. The revolving credit facility incurs a non-usage fee based on any undrawn amounts. As of December 31, 2021, there was no balance outstanding on the revolving credit facility and a total of $54.0 million outstanding on the term loan, of which $12.0 million is short-term and $42.0 million is long-term.

The following table sets forth the distribution of short-term borrowings and weighted average interest rates thereon *(dollars in thousands):*

| ​ ​ ​ Securities sold under agreements to repurchase | ​ | ​ ​ ​ Years Ended December 31, 2021 ​ | ​ ​ ​ 2020 ​ | ​ ​ ​ ​ 2019 ​ ​ ​ |
| --- | --- | ---: | ---: | ---: |

| Weighted average interest rate during period (1) | ​ | 1.79% | —% | —% |

(10) The weighted average interest rate is computed by dividing total interest for the period by the average daily balance outstanding.

In addition to the term loan, long-term debt includes funds borrowed from the FHLB which totaled $4.1 million and $4.8 million at December 31, 2021, and 2020, respectively.

On May 25, 2017, we issued $40.0 million of 3.75% senior notes that mature on May 25, 2022. The senior notes are payable semi-annually on each May 25 and November 25, commencing on November 25, 2017. The senior notes are not subject to optional redemption by the Company. Additionally, on May 25, 2017, we issued $60.0 million of fixed-to-floating rate subordinated notes that mature on May 25, 2027. The subordinated notes, which qualify as Tier 2 capital for First Busey, bear interest at an annual rate of 4.75% for the first five years after issuance and thereafter bear interest at a floating rate equal to 3-month LIBOR plus a spread of 2.919%, as calculated on each applicable determination date. The subordinated notes are payable semi-annually on each May 25 and November 25, commencing on November 25, 2017, during the five year fixed-term and thereafter on February 25, May 25, August 25, and November 25 of each year, commencing on August 25, 2022. The subordinated notes have an optional redemption in whole or in part on any interest payment date on or after May 25, 2022. The senior notes and subordinated notes are unsecured obligations of First Busey.

On June 1, 2020, we 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 First Busey, 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. 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 First Busey.

Unamortized debt issuance costs related to senior notes and subordinated notes are presented in the following table *(dollars in thousands):*

| ​ ​ ​ Unamortized debt issuance costs | ​ ​ | ​ ​ As of December 31, 2021 ​ ​ | ​ ​ | ​ ​ 2020 ​ ​ |
| --- | --- | ---: | --- | ---: |
| Senior notes issued in 2017 | ​ | $56 | ​ | $191 |
| Subordinated notes issued in 2017 | ​ | ​ 549 | ​ | ​ 651 |
| Subordinated notes issued in 2020 | ​ | ​ 1,678 | ​ | ​ 2,123 |
| Total unamortized debt issuance costs | ​ | $2,283 | ​ | $2,965 |

### Junior Subordinated Debt Owed to Unconsolidated Trusts

First 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 First 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 by First Busey, as Tier 1 regulatory capital. First 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 of $3.0 million remaining to be accreted. We had $71.6 million and $71.5 million of junior subordinated debt owed to unconsolidated trusts at December 31, 2021, and 2020, 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.

Average liquid assets are summarized in the table below *(dollars in thousands):*

| ​ ​ ​ Average liquid assets | ​ ​ ​ | ​ ​ ​ Years Ended December 31, 2021 ​ ​ ​ | ​ ​ ​ 2020 ​ ​ ​ | ​ ​ ​ 2019 ​ ​ ​ |
| --- | --- | ---: | ---: | ---: |
| Cash and due from banks | ​ | $133,711 ​ | $118,739 ​ | $114,619 ​ |
| Interest-bearing bank deposits | ​ | 630,687 ​ | 488,786 ​ | 312,580 ​ |
| Federal funds sold | ​ | — ​ | — ​ | 24 ​ |
| Total average liquid assets | ​ | $764,398 ​ | $607,525 ​ | $427,223 ​ |
| ​ | ​ | ​ ​ ​ | ​ ​ ​ | ​ ​ ​ |
| Average liquid assets as a percent of average total assets | ​ | 6.4% | 5.9% | 4.5% |

First Busey’s primary sources of funds consist of deposits, investment maturities and sales, loan principal repayments, and capital funds. At December 31, 2021, cash and unencumbered securities on our Consolidated Balance Sheets totaled $4.1 billion. Additional liquidity is provided by the ability to borrow from the FHLB, the Federal Reserve, First Busey’s revolving credit facility, or to utilize brokered deposits, as summarized in the table below *(dollars in thousands):*

| ​ ​ ​ Additional borrowing capacity available from: | ​ ​ ​ | ​ ​ As of December 31, 2021 ​ ​ | ​ ​ | ​ ​ 2020 ​ ​ |
| --- | --- | ---: | --- | ---: |
| FHLB | ​ | 1,536,019 | ​ | 1,336,655 |
| Federal Reserve | ​ | ​ 624,627 | ​ | ​ 507,813 |
| Revolving credit facility | ​ | 40,000 | ​ | 20,000 |
| Additional borrowing capacity | ​ | $2,200,646 | ​ | $1,864,468 |

As of December 31, 2021, 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 totaling $60.0 million and $122.0 million for the years ended December 31, 2021, and 2020, respectively.

### Off-Balance-Sheet Arrangements

Busey Bank routinely enters into commitments to extend credit and standby letters of credit in the normal course of business to meet the financing needs of its customers. As of December 31, 2021, and 2020, we had outstanding loan commitments and standby letters of credit of $2.0 billion and $1.8 billion, respectively. The balance of commitments to extend credit represents future cash requirements and some of these commitments may expire without being drawn upon. We anticipate we will have sufficient funds available to meet current loan commitments, including loan applications received and in process prior to the issuance of firm commitments.

### Contractual Obligations

### Cash Flows

Net cash flows provided by operating activities totaled $162.0 million in 2021, compared to $163.2 million in 2020. Significant items affecting the cash flows provided by operating activities include net income; the provision for credit losses; depreciation and amortization; gain on sales of mortgage loans, net of origination costs and activities related to the origination and sales of loans held for sale; and stock-based compensation. Net cash used to originate mortgage loans held for sale totaled $31.7 million in 2021, compared to $38.7 million of in 2020. Fluctuations in sales are a function of changes in market rates for mortgage loans, which influence refinance activity. Our provision for credit losses reflects a reserve release of to $15.1 million in 2021, compared to a provision expense of $38.8 million in 2020, reflecting forecasted improvements in macroeconomic conditions and asset quality, partially offset by core loan growth. Stock-based compensation increased to $7.9 million in 2021, compared to $7.1 million in 2020.

Net cash used in investing activities totaled $829.2 million in 2021, compared to $729.5 million in 2020. Significant investment activities are those associated with managing First Busey’s investment and loan portfolios, as well as acquisition activities. We purchased $2.3 billion of debt securities in 2021, compared to $1.3 billion in 2020. Investing outflows were partially offset with $228.3 million net cash received in connection with the CAC acquisition in 2021.

Net cash provided by financing activities totaled $814.7 million in 2021, compared to $725.6 million in 2020. Significant items affecting cash flows from financing activities are debt issuance, deposits, short-term borrowings, long-term debt, payment of dividends, and proceeds and redemption from stock issuances. Deposits, which represent First Busey’s primary funding source, increased by $767.5 million in 2021, compared to an increase of $776.4 million in 2020, excluding acquired deposits.

### Capital Resources

Our capital ratios are in excess of those required to be considered “well-capitalized” pursuant to applicable regulatory guidelines. The Federal Reserve Board 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 with capital buffer and December 31, 2021, capital ratios for First Busey and Busey Bank.

| ​ ​ ​ ​ | ​ ​ ​ | ​ Minimum Capital Requirements with Capital Buffer | ​ ​ ​ ​ | ​ As of December 31, 2021 First Busey Corporation | ​ ​ ​ | ​ Busey Bank | ​ ​ ​ ​ ​ |
| --- | --- | --- | ---: | --- | ---: | --- | ---: |
| Common Equity Tier 1 Capital to Risk Weighted Assets | ​ | ​ | 7.00% | ​ | 11.85% | ​ | 14.81% |
| Tier 1 Capital to Risk Weighted Assets | ​ | ​ | 8.50% | ​ | 12.73% | ​ | 14.81% |
| Total Capital to Risk Weighted Assets | ​ | ​ | 10.50% | ​ | 15.70% | ​ | 15.59% |
| Leverage Ratio of Tier 1 Capital to Average Assets | ​ | ​ | 6.50 ​ | ​ | 8.52% | ​ | 9.91% |

Management believes that no conditions or events have occurred since December 31, 2021, that would materially adversely change First Busey’s or Busey Bank’s capital classifications.

### New Accounting Pronouncements

We review new accounting standards as issued. Information relating to accounting pronouncements issued in 2021 and applicable to First Busey appears in “*Note 1. Significant Accounting Policies”* in the Notes to the Consolidated Financial Statements.

### Effects of Inflation

The effect of inflation on a financial institution differs significantly from the effect on an industrial company. While a financial institution’s operating expenses, particularly salaries, wages, and employee benefits, are affected by general inflation, the asset and liability structure of a financial institution consists largely of monetary items. Monetary items, such as cash, loans, and deposits, are those assets and liabilities which are or will be converted into a fixed number of dollars regardless of changes in prices. As a result, changes in interest rates have a more significant impact on a financial institution’s performance than does general inflation. For additional information regarding interest rates and changes in net interest income see “*Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Results of Operation — Three Years Ended December 31, 2021—Average Balance Sheets and Interest Rates”* and “*Item 7A. Quantitative and Qualitative Disclosures About Market Risk.”*

## Market risk

As filed, 3,100 characters.

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 First 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 First Busey’s business activities.

First 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 and +300 basis points. Due to the current low interest rate environment, a downward adjustment in federal fund rates was not meaningful as of December 31, 2021, or 2020. 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.

The interest rate risk of First Busey as a result of 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 ​ +100 +200 +300 |
| --- | --- | ---: |
| December 31, 2021 |  | 8.77% 17.19% 25.64% |
| December 31, 2020 |  | 7.40% 14.16% 20.20% |
| ​ | ​ | ​ ​ ​ ​ ​ ​ |
| **​** |  | **Year-Two: Basis Point Changes** **​** |
| **​** |  | **+100** **+200** **+300** |
| December 31, 2021 |  | 9.51% 18.22% 26.84% |
| December 31, 2020 |  | 9.59% 17.95% 25.40% |

Interest rate risk is monitored and managed within approved policy limits. 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.

### Changes in Internal Control Over Financial Reporting

During the three months ended December 31, 2021, 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.

### Evaluation of Disclosure Controls and Procedures

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, 2021, 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, 2021, 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 (i) accumulated and communicated to our management (including the Chief Executive Officer and Chief Financial Officer) to allow timely decisions regarding required disclosure, and (ii) recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms.

### Management’s Report on Internal Control Over Financial Reporting

First Busey’s management is responsible for establishing and maintaining adequate internal control over financial reporting. The Company’s internal control over financial reporting is a process designed under the supervision of the Company’s Chief Executive Officer and Chief Financial Officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of the Company’s Consolidated Financial Statements for external reporting purposes in accordance with U.S. generally accepted accounting principles.

As of December 31, 2021, management assessed the effectiveness of the Company’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. As permitted, management excluded from its assessment of internal control over financial reporting GSB from June 1, 2021, through August 14, 2021. This interim period from the acquisition date until GSB was merged into Busey Bank consisted of 74 days and GSB did not represent a material percentage of the Company’s net income, and GSB’s balance sheet accounted for 11.9% of the Company’s consolidated total assets as of the acquisition date. Based on this assessment, management determined that the Company maintained effective internal control over financial reporting as of December 31, 2021, based on the COSO criteria.

RSM US LLP, an independent registered public accounting firm that audited the Consolidated Financial Statements of the Company included in this Annual Report, has issued an audit opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021. The report, which expresses an unqualified opinion on the effectiveness of the Company’s internal control over financial reporting as of December 31, 2021, is included in this Item under the heading “*Report of Independent Registered Public Accounting Firm on Internal Control Over Financial Reporting.”*

### 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, 2021, 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, 2021, 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 financial statements of the Company and our report dated February 24, 2022, expressed an unqualified opinion.

As described in Management’s Report on Internal Control over Financial Reporting, management has excluded Glenview State Bank from its assessment of internal control over financial reporting from June 1, 2021 through August 14, 2021 because it was acquired by the Company in a purchase business combination on May 31, 2021 and merged into Busey Bank on August 14, 2021. We have also excluded Glenview State Bank from our audit of internal control over financial reporting for the period from June 1, 2021 through August 14, 2021. Glenview State Bank was a wholly owned subsidiary whose net income did not represent a material percentage of the Company’s net income, and whose balance sheet accounted for 11.9% of the Company’s consolidated total assets as of the acquisition date.

### 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.
