Note 1: Significant Accounting Policies

Nature of Operations

First Busey Corporation, a Nevada corporation organized in 1980, is a $12.4 billion financial holding company headquartered in Champaign, Illinois. Our common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.”

The Company operates and reports its business in three segments: Banking, Remittance Processing, and Wealth Management. The Banking operating segment provides a full range of banking services to individual and corporate customers through the Company’s wholly-owned bank subsidiaries, Busey Bank and GSB, with banking centers in Illinois; the St. Louis, Missouri metropolitan area; southwest Florida; and Indianapolis, Indiana. The Remittance Processing operating segment provides solutions for online bill payments, lockbox, and walk-in payments through the Company’s subsidiary, FirsTech. The Wealth Management operating segment provides a full range of asset management, investment, brokerage, fiduciary, philanthropic advisory, tax preparation, and farm management services to individuals, businesses, and foundations.

Basis of Financial Statement Presentation

These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in our 2020 Annual Report. These interim unaudited consolidated financial statements serve to update our 2020 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements.

We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.

In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

COVID-19

First Busey has continued to operate as an essential community resource during these challenging and unprecedented times. Federal bank regulatory agencies, along with their state counterparts, have issued a steady stream of guidance responding to the COVID-19 pandemic and have taken a number of steps to help banks navigate the pandemic and mitigate its impact.

The Company remains vigilant as the negative impacts of COVID-19, such as further margin compression and a deterioration in asset quality, could impact future quarters.

As part of the CARES Act, Congress appropriated approximately $349 billion for the creation of the PPP and then authorized a second phase for an additional $310 billion in PPP loans. The program provided payroll assistance for the nation’s nearly 30 million small businesses—and select nonprofits—in the form of 100% government-guaranteed low-interest loans from the SBA. On December 27, 2020, the Economic Aid Act extended the authority to make PPP loans through March 31, 2021, and revised certain PPP requirements. On March 30, 2021, the President signed the PPP Extension Act of 2021, which extended the PPP application deadline to May 31, 2021, or until funding was exhausted, which occurred on May 28, 2021. First Busey served as a bridge for these programs, actively helping existing and new business clients sign up for this important financial resource.

Use of Estimates

In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, the Company’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.

Subsequent Events

The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. On July 27, 2021, the Company announced its Personal Banking Transformation Plan which includes plans to close and consolidate 15 Busey Bank banking centers. In addition, the Company announced plans to consolidate two GSB banking centers, with the banking centers in connection with the integration of the acquisition. Each of these banking center closures is expected to occur in the fourth quarter of 2021. There were no other significant subsequent events for the quarter ended June 30, 2021, through the filing date of these unaudited consolidated financial statements.

Note 2: Acquisitions

Cummins-American Corp.

Effective May 31, 2021, the Company completed its acquisition of CAC, the holding company for GSB. The partnership will enhance the Company’s existing deposit, commercial banking, and wealth management presence in the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area. GSB’s results of operations were included in the Company’s results of operation beginning June 1, 2021. Busey will operate GSB as a separate banking subsidiary of Busey until it is merged with Busey Bank, which is expected to occur in the third quarter of 2021. At the time of the bank merger, all GSB banking centers will become branches of Busey Bank.

Under terms of the definitive agreement, each share of CAC common stock issued and outstanding as of the effective date was converted into the right to receive 444.4783 shares of First Busey common stock and $14,173.96 in cash, which reflects the adjustments made to the cash consideration in accordance with the terms of the definitive agreement. The fair value of the common shares issued as part of the consideration paid for CAC was determined on the basis of the closing price of the Company’s common shares on the last trading day immediately preceding the acquisition date of

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

May 31, 2021. As additional consideration provided to CAC’s shareholders in the merger, CAC paid a special dividend to its shareholders in the amount of $60 million, or $12,087.58 per share of CAC common stock, on May 28, 2021.

This transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged was recorded at estimated fair values on the date of acquisition. Fair values are considered provisional until final fair values are determined, or the measurement period has passed, but no later than one year from the acquisition date. Reviews of third-party valuations for loans, deposits, and other intangible assets are still being performed by management. Therefore, amounts are subject to change, and could change materially from the provisional amounts discussed below.

As the total consideration paid for CAC exceeded the provisional fair value of net assets acquired, estimated goodwill of $6.0 million was recorded as of the acquisition date. The amount of Goodwill recognized as a result of this transaction is expected to be fully tax deductible for federal income tax purposes in accordance with the Company’s election pursuant to Section 338(h)(10) of the Internal Revenue Code. Goodwill recorded for this transaction reflects synergies expected from the acquisition and expansion within the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area, and was assigned to the Banking operating segment.

The following table presents the estimated fair value of CAC’s assets acquired and liabilities assumed as of May 31, 2021 (dollars in thousands):

	Fair Value

Cash and cash equivalents	$	307,339
Securities		702,367

The fair value of PCD financial assets was $60.5 million on the date of acquisition. Gross contractual amounts receivable relating to the PCD financial assets was $65.2 million. The Company estimates, on the date of acquisition, that $4.2 million of the contractual cash flows specific to the PCD financial assets will not be collected.

During three and six months ended June 30, 2021, First Busey incurred $2.7 million and $3.0 million, respectively, in pre-tax acquisition expenses related to the acquisition of CAC, comprised primarily of professional fees, compensation expense, and data processing expense.

Debt securities available for sale are not within the scope of CECL, however, the accounting for credit losses on these securities is affected by ASC 326-30. As of June 30, 2021, the Company’s debt security portfolio consisted of 1,249 securities, compared to 1,114 securities as of December 31, 2020. The number of debt securities in the investment portfolio in an unrealized loss position as of June 30, 2021, was 252, representing an unrealized loss of 1.02% of the aggregate fair value, compared to 23 securities as of December 31, 2020, representing an unrealized loss of 0.30% of the aggregate fair value. Unrealized losses related to changes in market interest rates and market conditions that do not represent credit-related impairments. Furthermore, the Company does not intend to sell such securities and it is more likely than not that the Company will recover the amortized cost prior to being required to sell the debt securities.

collection of the amounts due according to the contractual terms of the debt securities is expected; therefore, the impairment related to noncredit factors is recognized in accumulated other comprehensive income (loss), net of applicable taxes. As of June 30, 2021, the Company did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of the Company’s stockholders’ equity.

Net accretable purchase accounting adjustments included in the balances above reduced loans by $11.5 million as of June 30, 2021, and $10.9 million as of December 31, 2020. The June 30, 2021, commercial balance includes loans originated under PPP with an amortized cost of $390.4 million, compared to $446.4 million in loans originated under PPP included in the December 31, 2020, balance.

During the three and six months ended June 30, 2021, the Company purchased retail real estate loans totaling $32.2 million, compared to no retail real estate loan purchases during the three months ended June 30, 2020, and $43.9 million of retail real estate loan purchases in the six months ended June 30, 2020.

The Company utilizes a loan grading scale to assign a risk grade to all of its loans. A description of the general characteristics of each grade is as follows:

● Pass – This category includes loans that are all considered acceptable credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that meet or exceed industry standards.

● Watch – This category includes loans that warrant a higher than average level of monitoring to ensure that weaknesses do not cause the inability of the credit to perform as expected. These loans are not necessarily a problem due to other inherent strengths of the credit, such as guarantor strength, but have above average concern and monitoring.

● Special mention – This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date.

● Substandard – This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

18

FIRST BUSEY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

● Substandard non-accrual – This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine.

All loans are graded at their inception. Commercial lending relationships that are $1.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $1.0 million are included in a portfolio review at least annually. Commercial loans greater than $0.35 million that have a grading of special mention or worse are typically reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more frequent review. GSB’s policies are similar in nature to Busey Bank’s policies and the Company is migrating such loan production and grading toward the Busey Bank policies.

Total past due and non-accrual loans	$	6,794	$	784	$	1,371	$	22,930

Gross interest income recorded on 90+ day past due loans and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms was $0.4 million for the three months ended June 30, 2021 and 2020. Gross interest income recorded on 90+ day past due loans and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms was $0.9 million for the six months ended June 30, 2021 and 2020. The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three and six months ended June 30, 2021 and 2020.

A summary of TDR loans is as follows (dollars in thousands):

	As of
	June 30,		December 31,
	2021		2020
Performing TDR loans:
In compliance with modified terms	$	2,518	$	3,814
30 – 89 days past due		—		15
Non-performing TDR loans		1,314		1,249
Total TDR loans	$	3,832	$	5,078

We did not newly classify any loans as performing TDRs during the three or six months ended June 30, 2021. Loans newly classified as performing TDRs during the three and six months ended June 30, 2020, included one retail real estate loan for $0.2 million for payment modification.

During the six months ended June 30, 2021, one commercial loan for $0.5 million was newly classified as a non-performing TDR for payment and rate modifications. This loan had been non-accrual since the second quarter of 2020. Also, during the six months ended June 30, 2021, one retail real estate loan for $0.1 million that had been a performing TDR for longer than 12 months, with a rate modification, became non-performing. During the six months ended June 30, 2020, three commercial loans for $0.5 million and one commercial real estate loan for $0.7 million were newly classified as non-performing TDRs for payment and rate modifications. These loans had been non-accrual since 2019.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

There were no TDRs that were entered into during the last 12 months that were subsequently classified as non-performing and had payment defaults (a default occurs when a loan is 90 days or more past due or transferred to non-accrual) during the three and six months ended June 30, 2021 or 2020.

Gross interest income that would have been recorded in the three and six months ended June 30, 2021 and 2020 if TDRs had performed in accordance with their original terms compared with their modified terms was insignificant.

Modified loans with payment deferrals that fall under the CARES Act or revised Interagency Statement that suspended requirements under GAAP related to TDR classification are not included in the Company’s TDR totals.

As of June 30, 2021, the Company had $0.2 million of residential real estate in the process of foreclosure. The Company follows FHFA guidelines on single-family foreclosures and real estate owned evictions on portfolio loans, as well as all COVID-19 related state foreclosure and eviction orders. The existing moratoriums on single-family foreclosures expired on July 31, 2021; however, moratoriums on single-family real estate owned evictions have been extended until September 30, 2021.

The following tables provide details of loans evaluated individually, segregated by category. The Company evaluates loans with disparate risk characteristics on an individual basis. The unpaid contractual principal balance represents the customer outstanding balance excluding any partial charge-offs. Amortized cost represents customer balances net of any partial charge-offs recognized on the loan. Average amortized cost is calculated using the most recent four quarters (dollars in thousands):

Management's evaluation as to the ultimate collectability of loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. Collateral dependent loans are loans in which repayment is expected to be provided solely by the underlying collateral and there are no other available and reliable sources of repayment. Loans are written down to the lower of cost or fair value of underlying collateral, less estimated costs to sell. As of June 30, 2021, there were $17.2 million of collateral dependent loans secured by real estate or business assets.

Management estimates the ACL balance using relevant available information from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of the Company’s historical loss experience beginning in 2010. As of June 30, 2021, the Company expects the markets in which it operates to experience continued economic uncertainty around the levels of delinquencies over the next 12 months. Management adjusted the historical loss experience for these expectations with an immediate reversion to historical loss rate beyond this forecast period. PPP loans were excluded from the ACL calculation as they are 100% government guaranteed.

The following tables detail activity in the ACL. Allocation of a portion of the ACL to one category does not preclude its availability to absorb losses in other categories (dollars in thousands):

Note 7: Regulatory Capital

The Company and its subsidiary banks are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. Capital amounts and classification also are subject to qualitative judgments by regulators about components, risk weightings, and other factors.

Banking regulations identify five capital categories for insured depository institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. As of June 30, 2021, and December 31, 2020, all capital ratios of the Company and its subsidiary banks exceeded the well capitalized levels under the applicable regulatory capital adequacy guidelines. Management believes that no events or changes have occurred subsequent to June 30, 2021, that would change this designation.

On March 27, 2020, the FDIC and other federal banking agencies published an interim final rule that provides those banking organizations adopting CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital and to phase in the aggregate impact of the deferral on regulatory capital over a subsequent three-year period. On August 26, 2020, the CECL final rule was finalized and was substantially similar to the interim final rule. Under this final rule, because the Company has elected to use the deferral option, the regulatory capital impact of our transition adjustments recorded on January 1, 2020, from the adoption of CECL will be deferred for two years, until January 1, 2022. In addition, 25 percent of the ongoing impact of CECL on our ACL, retained earnings, and average total consolidated assets from January 1, 2020, through the end of the two-year deferral period, each as reported for regulatory capital purposes, will be added to the deferred transition amounts (“adjusted transition amounts”) and deferred for the two-year period. At the conclusion of the two-year period the adjusted transition amounts will be phased-in for regulatory capital purposes at a rate of 25 percent per year, with the phased-in amounts included in regulatory capital at the beginning of each year. GSB adopted CECL as of the acquisition date, and based on the timing of the acquisition, GSB is not eligible for this deferral option.

In July 2013, U.S. federal banking authorities approved the Basel III Rule for strengthening international capital standards. The Basel III Rule introduced a capital conservation buffer, composed entirely of Common Equity Tier 1 Capital, which is added to the minimum risk-weighted asset ratios. The capital conservation buffer is not a minimum capital requirement; however, banking institutions with a ratio of Common Equity Tier 1 to risk-weighted assets below the capital conservation buffer will face constraints on dividends, equity repurchases, and discretionary bonus payments based on the amount of the shortfall. In order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments, banking institutions must maintain minimum ratios of (i) total capital to risk-weighted

Note 8: Stock-Based Compensation

Under the terms of the 2020 Equity Plan, the Company has granted restricted stock units, deferred stock units and performance-based restricted stock unit awards. The Company grants restricted stock units to members of management periodically throughout the year. Each restricted stock unit is equivalent to one share of the Company’s common stock. These units have requisite service periods ranging from one to five years, subject to accelerated vesting upon eligible retirement from the Company. Recipients earn quarterly dividend equivalents on their respective units which entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances.

The Company grants deferred stock units, which are restricted stock units with a deferred settlement date, to its directors and advisory directors. Each deferred stock unit is equivalent to one share of the Company’s common stock. Deferred stock units vest over a one-year period following the grant date. These units generally are subject to the same terms as restricted stock units under the 2020 Equity Plan, except that, following vesting, settlement occurs within 30 days following the earlier of separation from the board or a change in control of the Company. After vesting and prior to delivery, these units will continue to earn dividend equivalents.

The Company also grants performance-based restricted stock unit awards to members of management periodically throughout the year. Each performance-based restricted stock unit is equivalent to one share of the Company’s common stock. The number of units that ultimately vest will be determined based on the achievement of the market or other performance goals, subject to accelerated service-based vesting conditions upon eligible retirement from the Company.

The Company has outstanding stock options assumed from acquisitions.

Upon vesting/delivery, shares are expected (though not required) to be issued from treasury.

Note 10: Derivative Financial Instruments

The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. Additionally, the Company enters into derivative financial instruments, including interest rate lock commitments issued to residential loan customers for loans that will be held for sale, forward sales commitments to sell residential mortgage loans to investors, and interest rate swaps with customers and other third parties. See “Note 11: Fair Value Measurements” for further discussion of the fair value measurement of such derivatives.

Interest Rate Swaps Designated as Cash Flow Hedges

The Company entered into derivative instruments designated as cash flow hedges. For a derivative instrument that is designated and qualifies as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The change in fair value of components excluded from the assessment of effectiveness are recognized in current earnings.

Interest rate swaps with notional amounts totaling $70.0 million as of June 30, 2021, and December 31, 2020, were designated as cash flow hedges to hedge the risk of variability in cash flows (future interest payments) attributable to changes in the contractually specified 3-month LIBOR benchmark interest rate on the Company’s junior subordinated debt owed to unconsolidated trusts and were determined to be highly effective during the period. The gross aggregate fair value of the swaps of $2.0 million as of June 30, 2021, and $3.1 million as of December 31, 2020, is recorded in other liabilities in the unaudited Consolidated Balance Sheets, with changes in fair value recorded net of tax in other comprehensive income (loss). The Company expects the hedges to remain highly effective during the remaining terms of the swaps.

A summary of the interest-rate swaps designated as cash flow hedges is presented below (dollars in thousands):

	As of
	June 30,			December 31,
	2021			2020
Notional amount	$	70,000		$	70,000

Weighted average maturity, in years		2.36	yrs		2.85	yrs
Unrealized gains (losses), net of tax	$	(1,438)		$	(2,184)

Interest expense recorded on these swap transactions was $0.3 million and $0.6 million during the three and six months ended June 30, 2021, respectively. The Company expects $0.3 million of the unrealized loss to be reclassified from OCI to interest expense during the next three months. This reclassified amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to June 30, 2021.

Forward Sales Commitments

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

Amounts and fair values of mortgage banking derivatives included in the unaudited Consolidated Balance Sheets are summarized as follows (dollars in thousands):

The impact of the net gains or losses on derivative financial instruments related to interest rate lock commitments issued to residential loan customers for loans that will be held for sale and forward sales commitments to sell residential mortgage loans to loan investors are almost entirely offset by a corresponding change in the fair value of loans held for sale.

Interest Rate Swaps Not Designated as Hedges

The Company may offer derivative contracts to its customers in connection with their risk management needs. The Company manages the risk associated with these contracts by entering into equal and offsetting derivative agreements with a third-party dealer. These contracts support variable rate, commercial loan relationships totaling $408.5 million and $395.0 million as of June 30, 2021, and December 31, 2020, respectively. These derivatives generally worked together as an economic interest rate hedge, but the Company did not designate them for hedge accounting treatment. Consequently, changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Note 11: Fair Value Measurements

The fair value of an asset or liability is the price that would be received by selling that asset or paid in transferring that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820, Fair Value Measurement, establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

● Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

● Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

● Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to those Company assets and liabilities that are carried at fair value.

In general, fair value is based upon quoted market prices, when available. If such quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable data. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect, among other things, counterparty credit quality and the company's creditworthiness as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. While management believes the Company's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Debt Securities Available for Sale

Debt securities classified as available for sale are reported at fair value utilizing Level 2 measurements. The Company obtains fair value measurements from an independent pricing service. The independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid, and other market information. Because

36

FIRST BUSEY CORPORATION

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

many fixed income securities do not trade on a daily basis, the independent pricing service applies available information, focusing on observable market data such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing to prepare evaluations.

The independent pricing service uses model processes, such as the Option Adjusted Spread model, to assess interest rate impact and develop prepayment scenarios. Models and processes take into account market conventions. For each asset class, a team of evaluators gathers information from market sources and integrates relevant credit information, perceived market movements, and sector news into the evaluated pricing applications and models.

Market inputs that the independent pricing service normally seeks for evaluations of securities, listed in approximate order of priority, include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. The independent pricing service also monitors market indicators, industry, and economic events. For certain security types, additional inputs may be used or some of the market inputs may not be applicable. Evaluators may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs listed are available for use in the evaluation process for each security evaluation on a given day. Because the data utilized was observable, the securities have been classified as Level 2.

Equity Securities

Equity securities are reported at fair value utilizing Level 1 or Level 2 measurements. As applicable, for mutual funds, unadjusted quoted prices in active markets for identical assets are utilized to determine fair value at the measurement date and are classified as Level 1. For stock, quoted prices for identical or similar assets in markets that are not active are utilized and classified as Level 2.

Loans Held for Sale

Loans held for sale are reported at fair value utilizing Level 2 measurements. The fair value of the mortgage loans held for sale are measured using observable quoted market or contract prices or market price equivalents and are classified as Level 2.

Derivative Assets and Derivative Liabilities

Derivative assets and derivative liabilities are reported at fair value utilizing Level 2 measurements. Fair values of derivative assets and liabilities are determined based on prices that are obtained from a third-party which uses observable market inputs. Derivative assets and liabilities are classified as Level 2.

The following tables summarize financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2021, and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

Loans Evaluated Individually

The Company does not record portfolio loans at fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the collateral value is not sufficient, a specific reserve is recorded. Collateral values are estimated using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of unobservable inputs, fair values of individually evaluated collateral dependent loans have been classified as Level 3.

OREO

Non-financial assets measured at fair value include OREO (upon initial recognition or subsequent impairment). OREO properties are measured using a combination of observable inputs, including recent appraisals, and unobservable inputs. Due to the significance of unobservable inputs, all OREO fair values have been classified as Level 3.

Bank Property Held for Sale

Bank property held for sale represents certain banking center office buildings which the Company has closed and consolidated with other existing banking centers. Bank property held for sale is measured at the lower of amortized cost or fair value less estimated costs to sell. Fair values were based upon discounted appraisals or real estate listing prices.

Note 12: Earnings Per Common Share

Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding, which include deferred stock units that are vested but not delivered. Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if the Company’s outstanding stock options and warrants were exercised and restricted stock units were vested.

Earnings per common share have been computed as follows (dollars in thousands, except per share amounts):

ITEM 2. MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

OVERVIEW

First Busey is a $12.4 billion financial holding company headquartered in Champaign, Illinois. Our common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.”

Our three operating segments provide a full range of banking, remittance processing, and wealth management services through our subsidiaries, Busey Bank, GSB, and FirsTech, in Illinois; the St. Louis, Missouri metropolitan area; southwest Florida; and Indianapolis, Indiana.

The following discussion and analysis are intended to assist readers in understanding the financial condition and results of operations of the Company during the three and six months ended June 30, 2021, and should be read in conjunction with the Company’s unaudited consolidated financial statements and notes thereto included in this Quarterly Report, as well as the Company’s 2020 Annual Report.

EXECUTIVE SUMMARY

COVID-19

Although the progression of the COVID-19 pandemic in the United States has impacted the Company’s results of operations, the Company continues to navigate the economic environment caused by COVID-19 effectively and prudently and remains resolute in its focus on serving its customers, communities, and associates while protecting its balance sheet. The Company remains vigilant, given that negative impacts of COVID-19, such as further margin compression and a deterioration in asset quality, could impact future quarters.

Our commercial and consumer banking products and services are delivered in Illinois, Missouri, Indiana, and Florida. 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.

Federal, state, and local governments, and regulatory authorities have enacted and issued a range of policy responses to the COVID-19 pandemic. See the Company’s 2020 Annual Report for information on policy and regulatory actions taken during 2020. 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.

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 June 30, 2021, the Company had 49 commercial loans remaining on payment deferrals representing $143.5 million in loans,

46

consisting of $10.4 million in full payment deferrals and $133.1 million in interest only modifications. In addition, as of June 30, 2021, the Company had eight retail loans on payment deferrals representing $0.8 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 First Busey’s PPP loans as of June 30, 2021, (dollars in thousand):

(1) A non-GAAP financial measure.  See “Non-GAAP Financial Information” included in this Quarterly Report.

(2) Calculated using adjusted net income, a non-GAAP measure.  See “Non-GAAP Financial Information” included in this Quarterly Report.

(3) Annualized measure.

On May 31, 2021, the Company completed its acquisition of CAC, the holding company for GSB. GSB, founded in 1920, is a commercial bank headquartered in Glenview, Illinois. Busey will operate GSB as a separate banking subsidiary of Busey until it is merged with Busey Bank, which is expected to occur in the third quarter of 2021. Results for the three and six months ended June 30, 2021, include one month of operating results for GSB.

The Company views certain non-operating items, including acquisition-related and restructuring charges, as adjustments to net income reported under GAAP. Non-operating pre-tax adjustments for the three and six months ended June 30, 2021, included $2.7 million and $3.0 million of expenses related to acquisitions, respectively. A reconciliation of non-GAAP measures – including adjusted pre-provision net revenue, adjusted net income, adjusted earnings per share, adjusted return on average assets, adjusted net interest margin, 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 the Company believes facilitates the assessment of its financial results and peer comparability, is included in tabular form in this Quarterly Report. See “Non-GAAP Financial Information.”

Banking Center Markets

As of June 30, 2021, we served the Illinois banking market with 53 Busey Bank banking centers and seven GSB banking centers. 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. However, the financial condition of the state of Illinois, in which the largest portion of the Company’s customer base resides, is characterized by low credit ratings and budget deficits.

As of June 30, 2021, Busey Bank had 10 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. Fourteen of our banking centers in Illinois are located within the boundaries of the St. Louis Metropolitan Statistical Area.

As of June 30, 2021, Busey Bank had four 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.

As of June 30, 2021, Busey Bank had 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.

The Company has evaluated and expects to close and consolidate 15 Busey Bank banking centers and two GSB banking centers in the fourth quarter of 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%. 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 Consolidated Average Balance Sheets and interest rates were impacted in 2021 and 2020 by numerous factors surrounding COVID-19. The Federal Open Market Committee rate cuts during the first quarter of 2020 have contributed to the decline in net interest margin over the past year, as assets, in particular commercial loans, repriced more quickly and to a greater extent than liabilities. The net interest margin has also been negatively impacted by the 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.

The Company remains substantially core deposit funded, with robust liquidity and significant market share in the communities we serve.

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% for the three months ended June 30, 2021, compared to 2.83% for the same period in 2020, and was 2.46% for the six months ended June 30, 2021, compared to 2.89% for the same period in 2020, each on a tax equivalent basis.

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

	2021		2020
First Quarter	2.72	%	3.20	%
Second Quarter	2.50	%	3.03	%
Third Quarter			2.86	%
Fourth Quarter			3.06	%

Factors contributing to the 22-basis point decline in net interest margin during the second quarter of 2021, compared to the first quarter of 2021, include:

● Reduced recognition of purchase accounting accretion contributed -2 basis points

● Reduction in PPP fee recognition contributed -3 basis points

● Inclusion of GSB for one month contributed -5 basis points

● Asset rate volume mix contributed -15 basis points

● Funding costs improved +3 basis points, partially offsetting the declines

Management attempts to mitigate the effects of an unpredictable interest-rate environment through effective portfolio management, prudent loan underwriting, effective funding cost control, meaningful non-interest income contribution, and operational efficiencies. Please refer to the Notes to Consolidated Financial Statements in the Company’s 2020 Annual Report for a description of accounting policies underlying the recognition of interest income and expense.

Remittance processing revenue relates to our payment processing company, FirsTech. Remittance processing revenue increased by 17.0% to $4.3 million for the three months ended June 30, 2021, compared to $3.7 million for the same period in 2020. Remittance processing revenue increased by 17.3% to $8.8 million for the six months ended June 30, 2021, compared to $7.5 million for the same period in 2020. Fluctuations in remittance processing revenue were primarily the result of increased payment and volume activity at FirsTech. Remittance processing adds important diversity to our revenue stream while widening our array of service offerings to larger commercial clients both within our footprint and nationally. The Company is currently making strategic investments in FirsTech to further enhance future growth.

Mortgage revenue decreased 35.4% to $1.7 million for the three months ended June 30, 2021, compared to $2.7 million for the same period in 2020, primarily as a result of declines in sold-loan mortgage volume. Mortgage revenue increased 8.0% to $4.4 million for the six months ended June 30, 2021, compared to $4.1 million for the same period in 2020. General economic conditions and interest rate volatility may impact fees in future quarters.

Income on bank owned life insurance decreased 35.3%, to $1.5 million for the three months ended June 30, 2021, compared to $2.3 million for the same period in 2020. Income on bank owned life insurance decreased 26.9%, to $2.4 million for the six months ended June 30, 2021, compared to $3.3 million for the same period in 2020. Decreases primarily resulted from a $0.8 million decline in earnings on death proceeds for the three and six months ended June 30, 2021.

Other income increased 69.6% to $2.9 million for the three months ended June 30, 2021, compared to $1.7 million for the same period in 2020.  Other income increased 59.4% to $4.1 million for the six months ended June 30, 2021, compared to $2.5 million for the same period 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 non-interest expense increased by 18.0% to $62.6 million for the three months ended June 30, 2021, compared to $53.1 million for three months ended June 30, 2020. Total non-interest expense increased by 3.1% to $117.1 million for the six months ended June 30, 2021, compared to $113.6 million for six months ended June 30, 2020. Contributing to the increases, non-operating acquisition related expenses of $2.7 million and $3.0 million were included in total non-interest expense for the three and six months ended June 30, 2021, respectively, compared to $0.5 million and $0.6 million for the three and six months ended June 30, 2020, respectively. Deferral of origination costs on PPP loans lowered expenses by $0.4 million and $2.7 million for the three and six months ended June 30, 2021, respectively, compared to $4.9 million for the three and six months ended June 30, 2020. Results for the three and six months ended June 30, 2021, include one month of operating expenses for GSB totaling $2.5 million, excluding non-operating items, and the Company expects efficiencies associated with the acquisition of CAC to be realized after the banks merge.

Salaries, wages, and employee benefits increased by 22.2% to $34.9 million for the three months ended June 30, 2021, compared to $28.6 million for the same period in 2020. Salaries, wages, and employee benefits increased by 4.3% to $65.3 million for the six months ended June 30, 2021, compared to $62.6 million for the same period in 2020. The increase was driven by the addition of 137 full-time equivalents from GSB. Results for the three and six months ended June 30, 2021, include $2.4 million of GSB expenses for salaries, wages, and employee benefits for the one month since acquisition, which included $1.1 million of non-operating acquisition related expenses. In addition, deferral of PPP loan origination costs lowered expenses for salaries, wages, and employee benefits by $0.3 million and $2.1 million for the three and six months ended June 30, 2021, respectively, compared to $3.8 million for the three and six months ended June 30, 2020.

Combined, net occupancy expense of premises and furniture and equipment expense decreased by 9.6% to $6.3 million for the three months ended June 30, 2021, compared to $7.0 million for the same period in 2020. Combined, net occupancy expense of premises and furniture and equipment expense decreased by 8.8% to $12.9 million for the six months ended June 30, 2021, compared to $14.1 million for the same period in 2020. These decreases in 2021 were primarily related to savings achieved through the closure of 12 banking centers in October of 2020. On July 27, 2021, the Company announced its Personal Banking Transformation Plan to close and consolidate 15 Busey Bank banking centers as well as two GSB banking centers to be consolidated as part of the acquisition integration plan, with the banking center closures expected to occur in the fourth quarter of 2021.

Professional fees increased by 16.4% to $2.3 million for the three months ended June 30, 2021, compared to $2.0 million for the same period of 2020. Professional fees increased by 11.7% to $4.3 million for the six months ended June 30, 2021, compared to $3.8 million for the same period of 2020. Professional fee variances were largely influenced by acquisition expenses. Results for the three and six months ended June 30, 2021, include $0.9 million and $1.3 million, respectively, of non-operating professional fee expenses related to the acquisition.

Amortization of intangible assets increased by 5.2% to $2.7 million for the three months ended June 30, 2021, compared to $2.5 million for the same period in 2020. Amortization of intangible assets was $5.1 million for the six months ended June 30, 2021 and 2020. Results for the three and six months ended June 30, 2021, include $0.3 million of amortization expense related to GSB.

Interchange expense increased by 20.4% to $1.4 million for the three months ended June 30, 2021, compared to $1.2 million for the same period in 2020. Interchange expense increased by 23.6% to $2.9 million for the six months ended June 30, 2021, compared to $2.4 million for the same period in 2020. Fluctuations in interchange expense were primarily the result of increased payment and volume activity at FirsTech.

Other expense increased by 31.2% to $10.2 million for the three months ended June 30, 2021, compared to $7.8 million for the same period in 2020. Other expense increased by 2.6% to $17.6 million for the six months ended June 30, 2021, compared to $17.2 million for the same period in 2020. Increases were across multiple expense categories, including New Market Tax Credit amortization and business development expenses, partially offset by lower MSR valuation impairment and provision for unfunded commitments. Also contributing to the increase, deferral of PPP loan origination costs lowered other expenses by $0.1 million and $0.6 million for the three and six months ended June 30, 2021, respectively, compared to $1.1 million during the three and six months ended June 30, 2020. Results for the three and six months ended June 30, 2021, include one month of other expenses for GSB totaling $0.4 million.

The efficiency ratio⁽¹⁾, 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 61.7% for the three months ended June 30, 2021, compared to 51.0% for the three months ended June 30, 2020. The efficiency ratio was 58.2% for the six months ended June 30, 2021, compared to 55.3% for the same period in 2020.

The adjusted efficiency ratio⁽¹⁾ was 58.9% for the three months ended June 30, 2021, compared to 50.5% for the three months ended June 30, 2020. The adjusted efficiency ratio was 56.6% for the six months ended June 30, 2021, compared to 55.0% for the same period in 2020. The Company remains focused on expense discipline.

Income Taxes

The effective income tax rates of 18.7% and 20.7% for the three and six months ended June 30, 2021, respectively, were lower than the combined federal and state statutory rate of approximately 28% due to tax exempt interest income, such as municipal bond interest and bank owned life insurance income, and investments in various federal and state tax credits, including an Illinois new market tax credit. The Company continues to monitor evolving federal and state tax legislation and its potential impact on operations on an ongoing basis. As of June 30, 2021, the Company was not under examination by any tax authority; however, Banc Ed, which the Company acquired on January 31, 2019, is under examination by the Illinois Department of Revenue for its 2009 to 2016 income tax filings.

GSB contributed $1.4 billion in assets, $422.4 million in portfolio loans, net of $8.0 million ACL, and $1.3 billion in total deposits as of June 30, 2021.

Portfolio Loans

The Company believes that making sound and profitable loans is a necessary and desirable means of employing funds available for investment. The Company 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 are similar in nature to Busey Bank’s policies and the Company is migrating such loan production toward Busey Bank’s policies in advance of the merger of the banks. While not specifically limited, the Company attempts to focus its lending on short to intermediate-term (0-7 years) loans in geographic areas within 125 miles of its 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 the Banks. The Company attempts to utilize government-assisted lending programs, such as the SBA and U.S. Department of Agriculture lending programs, when prudent. Generally, loans are collateralized by assets, primarily real estate, and guaranteed by individuals. Loans are expected to be repaid primarily from cash flows of the borrowers or from proceeds from the sale of selected assets of the borrowers.

Management reviews and approves the Company’s lending policies and procedures on a regular basis. Management routinely (at least quarterly) reviews the Company’s ACL in conjunction with reports related to loan production, loan quality, concentrations of credit, loan delinquencies, and non-performing and potential problem loans. The Company’s underwriting standards are designed to encourage relationship banking rather than transactional banking. Relationship banking implies a primary banking relationship with the borrower that includes, at a minimum, an active deposit banking relationship in addition to the lending relationship. Significant underwriting factors, in addition to location, duration, a

58

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, the Company limits 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, the Company took actions starting in early March 2020 to escalate the monitoring of susceptible industry sectors within its portfolio. The Company anticipates that organic loan growth will slow in future quarters as a result of COVID-19 and the related impact on economic conditions in the Company’s market areas.

At no time is a borrower’s total borrowing relationship permitted to exceed the Company’s regulatory lending limit. The Company generally limits such relationships to amounts substantially less than the regulatory limit. Loans to related parties, including executive officers and directors of the Company and its subsidiaries, are reviewed for compliance with regulatory guidelines by the Company’s board of directors at least annually.

The Company maintains an independent loan review department that reviews loans for compliance with the Company’s loan policy on a periodic basis. In addition, the loan review department reviews risk assessments made by the Company’s credit department, lenders, and loan committees. Results of these reviews are presented to management and the audit committee at least quarterly.

The Company’s lending activities 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. A description of each of the lending areas can be found in the Company’s 2020 Annual Report. The significant majority of the Company’s portfolio lending activity occurs in its Illinois and Missouri markets, with the remainder in the Indiana and Florida markets.

Portfolio loans increased by 5.5% to $7.2 billion as of June 30, 2021, compared to $6.8 billion as of December 31, 2020. Commercial balances (consisting of commercial, commercial real estate, and real estate construction loans), excluding PPP loans, increased $162.6 million since December 31, 2020. Retail real estate and retail other loans increased $264.9 million since December 31, 2020. As of June 30, 2021, loan balances included $144.3 million of GSB commercial loans and $286.1 million of GSB retail real estate and retail other loans.

Allowance and Provision for Credit Losses

The ACL is a significant estimate in the Company’s unaudited consolidated financial statements, affecting both earnings and capital. The methodology adopted influences, and is influenced by, the Company’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.

Provision for credit loss expense decreased due to a reserve release of $1.7 million for the three months ended June 30, 2021, compared to a provision expense of $12.9 million for the same period in 2020. Provision for credit loss expense decreased due to a reserve release of $8.5 million for the six months ended June 30, 2021, compared to a provision expense of $30.1 million for the same period in 2020. Specifically, during the three and six months ended June 30, 2021, Busey Bank recorded a $5.5 million and $12.3 million negative provision for credit losses, respectively, amid improved US economic outlooks. Also, during the three and six months ended June 30, 2021, as a result of the acquisition, GSB recorded a Day 1 ACL of $4.2 million for PCD loans and a provision for credit losses of $3.8 million.

The relationship between our portfolio loan balances and our ACL is summarized as follows, as of each of the dates indicated (dollars in thousands):

As of June 30, 2021, management believed the level of the ACL to be appropriate based upon the information available. However, additional losses may be identified in our loan portfolio as new information is obtained. 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.

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 principal and interest amounts contractually due are brought current and future payments are reasonably assured.

60

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.

The following table sets forth information concerning non-performing loans and performing restructured loans, as of each of the dates indicated (dollars in thousands):

Classified assets to the Banks Tier 1 Capital and ACL		5.72	%		7.76	%		8.47	%		9.58	%		10.47	%

Non-performing loan balances increased 16.5% to $28.3 million as of June 30, 2021, compared with $24.3 million as of December 31, 2020, primarily as a result of $4.4 million of acquired GSB non-performing loans. Continued disciplined credit management resulted in non-performing loans as a percentage of total loans of 0.39% as of June 30, 2021, compared to 0.34% as of March 31, 2021, and 0.35% as of June 30, 2020. Excluding the amortized cost of PPP loans, non-performing loans as a percentage of total loans was 0.42% as of June 30, 2021, compared to 0.37% as of March 31, 2021, and 0.39% as of June 30, 2020.

Asset quality metrics remain dependent upon market-specific economic conditions, and specific measures may fluctuate from period to period. If economic conditions were to deteriorate as a result of COVID-19, the Company would expect the credit quality of our loan portfolio to decline and loan defaults to increase.

Potential Problem Loans

Potential problem loans are loans classified as substandard which are not categorized as impaired, restructured, non-accrual, or 90+ days past due, but where current information indicates that the borrower may not be able to comply with loan repayment terms. Management assesses the potential for loss on such loans and considers the effect of any potential loss in determining its provision for expected credit losses. Potential problem loans decreased by 34.9% to $44.8 million as of June 30, 2021, compared to $68.8 million as of 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 June 30, 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.

61

To alleviate some of the financial hardships faced as a result of COVID-19, the Company offered a Financial Relief Program to qualifying customers. The program included options for short-term loan payment deferrals and certain fee waivers. As of June 30, 2021, the Company had 49 commercial loans on payment deferrals representing $143.5 million in loans. Of this balance, $10.4 million remained on full payment deferral, with the remaining $133.1 million on interest only modification. In addition, as of June 30, 2021, the Company had eight retail loans on payment deferrals representing $0.8 million in loans. As these deferrals expire, the Company will continue to monitor credits for potential problem loans.

Deposits

Total deposits increased 19.1% to $10.3 billion as of June 30, 2021, compared to $8.7 billion as of December 31, 2020. GSB deposits accounted for $1.3 billion of the increase. We focus on deepening our relationships with customers to foster core deposit growth, allowing us to reduce our reliance on wholesale funding. Recent fluctuations in deposit balances can be attributed to the retention of PPP loan funding in customer deposit accounts, the impacts of economic stimulus payments to consumers, other core deposit growth, and the seasonality of public funds.

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 the Company’s operating, investing, lending, and financing activities during any given period.

First Busey’s primary sources of funds consist of deposits, investment maturities and sales, loan principal repayments, and capital funds. Additional liquidity is provided by the ability to borrow from the FHLB, the Federal Reserve, First Busey’s revolving credit facility, or to utilize brokered deposits. As of June 30, 2021, the Company had additional capacity to borrow $1.2 billion from the FHLB and $476.5 million from the Federal Reserve. The Company has the ability to pledge PPP loans as collateral to either the FHLB or Federal Reserve Discount Window to increase the availability to borrow against any potential short-term funding needs.

As of June 30, 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.

OFF-BALANCE-SHEET ARRANGEMENTS

The Banks routinely enter into commitments to extend credit and standby letters of credit in the normal course of business to meet the financing needs of their customers. As of June 30, 2021, we had outstanding loan commitments and standby letters of credit of $1.8 billion, consistent with our December 31, 2020, balances. 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.

As of June 30, 2021, our reserve for unfunded commitments was $7.2 million, compared to $7.3 million as of December 31, 2020. Provision expense for unfunded commitments decreased due to a reserve release of $0.5 million and $0.1 million for the three and six months ended June 30, 2021, respectively, compared to an expense of $0.6 million and $1.6 million for the three and six months ended June 30, 2020. During the three and six months ended June 30, 2021, Busey Bank recorded a $0.6 million negative provision, and a $0.2 million negative provision, respectively, which was partially offset by a Day 1 provision of $0.2 million recorded by GSB as a result of the acquisition.

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 June 30, 2021, capital ratios for First Busey, Busey Bank, and GSB.

	Minimum Capital			As of June 30, 2021
	Requirements with			First Busey			Busey
	Capital Buffer			Corporation			Bank			GSB
Total Capital to Risk Weighted Assets		10.50	%		16.41	%		16.22	%		18.20	%
Tier 1 Capital to Risk Weighted Assets		8.50	%		13.18	%		15.30	%		16.95	%

NON-GAAP FINANCIAL INFORMATION

This Quarterly Report contains certain financial information determined by methods other than in accordance with GAAP. These measures include adjusted pre-provision net revenue, adjusted net income, adjusted diluted earnings per share, adjusted return on average assets, adjusted net interest margin, 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. 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 directly comparable GAAP financial measures – specifically net revenue in the case of adjusted pre-provision net revenue, 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 non-interest income and total non-interest expense in the case of 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 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 non-interest items and provides 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.

FORWARD-LOOKING STATEMENTS

Statements made in this document, other than those concerning historical financial information, may be considered forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 with respect to the financial condition, results of operations, plans, objectives, future performance, and business of the Company. Forward-looking statements, which may be based upon beliefs, expectations, and assumptions of the Company’s management, and on information currently available to management, are generally identifiable by the use of words such as “believe,” “expect,” “anticipate,” “plan,” “intend,” “estimate,” “may,” “will,” “would,” “could,” “should,” or other similar expressions. Additionally, all statements in this document, including forward-looking statements, speak only as of the date they are made, and the Company undertakes no obligation to update any statement in light of new information or future events. A number of factors, many of which are beyond the Company’s ability to control or predict, could cause actual results to differ materially from those in the Company’s forward-looking statements. These factors include, among others, the following: (i) the strength of the local, state, national, and international economy (including the impact of the current presidential administration); (ii) the economic impact of any future terrorist threats or attacks, widespread disease or pandemics (including the COVID-19 pandemic), or other adverse external events that could cause economic deterioration or instability in credit markets; (iii) changes in state and federal laws, regulations, and governmental policies concerning the Company’s general business; (iv) changes in accounting policies and practices, including FASB’s CECL impairment standards; (v) changes in interest rates and prepayment rates of the Company’s assets (including the impact of the LIBOR phase-out); (vi) increased competition in the financial services sector and the inability to attract new customers; (vii) changes in technology and the ability to develop and maintain secure and reliable electronic systems; (viii) the loss of key executives or associates; (ix) changes in consumer spending; (x) unexpected results of current and/or future acquisitions, which may include failure to realize the anticipated benefits of any acquisition and the possibility that transaction costs may be greater than anticipated; (xi) unexpected outcomes of existing or new litigation involving the Company; and (xii) the economic impact of exceptional weather occurrences such as tornadoes, hurricanes, floods, and blizzards. These risks and uncertainties should be considered in evaluating forward-looking statements and undue reliance should not be placed on such statements. Additional information concerning the Company and its business, including additional factors that could materially affect its financial results, is included in the Company’s filings with the SEC.

CRITICAL ACCOUNTING ESTIMATES

First Busey has established various accounting policies that govern the application of GAAP in the preparation of its unaudited Consolidated Financial Statements. Significant accounting policies are described in “Note 1. Significant Accounting Policies” of the Company’s 2020 Annual Report.

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 the Company’s 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.

68

Debt securities available for sale are not within the scope of CECL; however, the accounting for credit losses on these securities is affected by ASC 326-30. 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, the Company must first determine if it intends to sell the security or if it is more likely than not that it will be required to sell the security before the fair value increases to at least the amortized cost basis. If either of those selling events is expected, the Company will write down the amortized cost basis of the security to its fair value. This is achieved by writing off any previously recorded ACL balance related to the debt security, if applicable, and recognizing any incremental impairment through earnings. If the Company does not intend to sell the security, nor believes it more likely than not will be required to sell the security before the fair value recovers to the amortized cost basis, the Company 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.

The Company considers the following factors in assessing whether the decline is due to a credit loss:

● Extent to which the fair value is less than the amortized cost basis.

● Adverse conditions specifically related to the security, an industry, or a geographic area (for example, changes in the financial condition of the issuer of the security, or in the case of an asset-backed debt security, in the financial condition of the underlying loan obligors).

● Payment structure of the debt security and the likelihood of the issuer being able to make payments that increase in the future.

● Failure of the issuer of the security to make scheduled interest or principal payments.

● 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 ACL balance for the debt security through the provision for credit losses. Impairment related to noncredit factors is recognized in accumulated other comprehensive income, 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 326-30. However, the offset to record the ACL at the date of acquisition on acquired loans depends on whether or not the loan is classified as PCD. The ACL for PCD loans is recorded through a gross-up effect, while the ACL 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, the Company assess the potential for impairment on an annual basis or more frequently if events and circumstances indicate that goodwill might be impaired. The Company will continue to monitor events around COVID-19 and its potential impact on goodwill.

69

Income Taxes

The Company 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 unaudited Consolidated Statements of Income. Accrued and deferred taxes, as reported in other assets or other liabilities in the unaudited 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

The Company calculates the ACL at each reporting date. The Company recognizes an ACL for the lifetime expected credit losses for the amount the Company does not expect to collect. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the collectability of the reported book value. The calculation also contemplates that the Company may not be able to make or obtain such forecasts for the entire life of the financial assets and requires a reversion to historical credit loss information.

In determining the ACL, management relies predominantly on a disciplined credit review and approval process that extends to the full range of the Company’s credit exposure. The ACL must be determined on a collective (pool) basis when similar risk characteristics exists. On a case-by-case basis, the Company may conclude a loan should be evaluated on an individual basis based on the disparate risk characteristics.

Loans deemed uncollectible are charged against and reduce the ACL. A provision for credit losses is charged to current expense and acts to replenish the ACL in order to maintain the ACL at a level that management deems adequate. Determining the ACL involves significant judgments and assumptions by management. Because of the nature of the judgments and assumptions made by management, actual results may differ from these judgments and assumptions.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Market risk is the risk of changes in asset values due to movements in underlying market rates and prices. Interest rate risk is a type of market risk to earnings and capital arising from movements in interest rates. Interest rate risk is the most significant market risk affecting 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 June 30, 2021 or December 31, 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.

70

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
June 30, 2021	7.07	%	12.86	%	17.90	%
December 31, 2020	7.40	%	14.16	%	20.20	%

	Year-Two: Basis Point Changes
	+100		+200		+300
June 30, 2021	8.81	%	15.72	%	21.63	%
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.

ITEM 4. CONTROLS AND PROCEDURES

Nature of Operations

First Busey Corporation, a Nevada corporation organized in 1980, is a $12.4 billion financial holding company headquartered in Champaign, Illinois. Our common stock is traded on The Nasdaq Global Select Market under the symbol “BUSE.”

The Company operates and reports its business in three segments: Banking, Remittance Processing, and Wealth Management. The Banking operating segment provides a full range of banking services to individual and corporate customers through the Company’s wholly-owned bank subsidiaries, Busey Bank and GSB, with banking centers in Illinois; the St. Louis, Missouri metropolitan area; southwest Florida; and Indianapolis, Indiana. The Remittance Processing operating segment provides solutions for online bill payments, lockbox, and walk-in payments through the Company’s subsidiary, FirsTech. The Wealth Management operating segment provides a full range of asset management, investment, brokerage, fiduciary, philanthropic advisory, tax preparation, and farm management services to individuals, businesses, and foundations.

Basis of Financial Statement Presentation

These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in our 2020 Annual Report. These interim unaudited consolidated financial statements serve to update our 2020 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements.

We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.

In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

COVID-19

First Busey has continued to operate as an essential community resource during these challenging and unprecedented times. Federal bank regulatory agencies, along with their state counterparts, have issued a steady stream of guidance responding to the COVID-19 pandemic and have taken a number of steps to help banks navigate the pandemic and mitigate its impact.

The Company remains vigilant as the negative impacts of COVID-19, such as further margin compression and a deterioration in asset quality, could impact future quarters.

As part of the CARES Act, Congress appropriated approximately $349 billion for the creation of the PPP and then authorized a second phase for an additional $310 billion in PPP loans. The program provided payroll assistance for the nation’s nearly 30 million small businesses—and select nonprofits—in the form of 100% government-guaranteed low-interest loans from the SBA. On December 27, 2020, the Economic Aid Act extended the authority to make PPP loans through March 31, 2021, and revised certain PPP requirements. On March 30, 2021, the President signed the PPP Extension Act of 2021, which extended the PPP application deadline to May 31, 2021, or until funding was exhausted, which occurred on May 28, 2021. First Busey served as a bridge for these programs, actively helping existing and new business clients sign up for this important financial resource.

The following table summarizes First Busey’s PPP loans as of June 30, 2021, (dollars in thousands):

Use of Estimates

In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, the Company’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.

Subsequent Events

The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. On July 27, 2021, the Company announced its Personal Banking Transformation Plan which includes plans to close and consolidate 15 Busey Bank banking centers. In addition, the Company announced plans to consolidate two GSB banking centers, with the banking centers in connection with the integration of the acquisition. Each of these banking center closures is expected to occur in the fourth quarter of 2021. There were no other significant subsequent events for the quarter ended June 30, 2021, through the filing date of these unaudited consolidated financial statements.

Note 2: Acquisitions

Cummins-American Corp.

Effective May 31, 2021, the Company completed its acquisition of CAC, the holding company for GSB. The partnership will enhance the Company’s existing deposit, commercial banking, and wealth management presence in the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area. GSB’s results of operations were included in the Company’s results of operation beginning June 1, 2021. Busey will operate GSB as a separate banking subsidiary of Busey until it is merged with Busey Bank, which is expected to occur in the third quarter of 2021. At the time of the bank merger, all GSB banking centers will become branches of Busey Bank.

Under terms of the definitive agreement, each share of CAC common stock issued and outstanding as of the effective date was converted into the right to receive 444.4783 shares of First Busey common stock and $14,173.96 in cash, which reflects the adjustments made to the cash consideration in accordance with the terms of the definitive agreement. The fair value of the common shares issued as part of the consideration paid for CAC was determined on the basis of the closing price of the Company’s common shares on the last trading day immediately preceding the acquisition date of

May 31, 2021. As additional consideration provided to CAC’s shareholders in the merger, CAC paid a special dividend to its shareholders in the amount of $60 million, or $12,087.58 per share of CAC common stock, on May 28, 2021.

This transaction was accounted for using the acquisition method of accounting and, accordingly, assets acquired, liabilities assumed, and consideration exchanged was recorded at estimated fair values on the date of acquisition. Fair values are considered provisional until final fair values are determined, or the measurement period has passed, but no later than one year from the acquisition date. Reviews of third-party valuations for loans, deposits, and other intangible assets are still being performed by management. Therefore, amounts are subject to change, and could change materially from the provisional amounts discussed below.

As the total consideration paid for CAC exceeded the provisional fair value of net assets acquired, estimated goodwill of $6.0 million was recorded as of the acquisition date. The amount of Goodwill recognized as a result of this transaction is expected to be fully tax deductible for federal income tax purposes in accordance with the Company’s election pursuant to Section 338(h)(10) of the Internal Revenue Code. Goodwill recorded for this transaction reflects synergies expected from the acquisition and expansion within the Chicago-Naperville-Elgin, IL-IN-WI Metropolitan Statistical Area, and was assigned to the Banking operating segment.

The following table presents the estimated fair value of CAC’s assets acquired and liabilities assumed as of May 31, 2021 (dollars in thousands):

	Fair Value

Consideration paid:

Common stock		59,105
Total consideration paid	$	129,463
Goodwill	$	5,985

The fair value of PCD financial assets was $60.5 million on the date of acquisition. Gross contractual amounts receivable relating to the PCD financial assets was $65.2 million. The Company estimates, on the date of acquisition, that $4.2 million of the contractual cash flows specific to the PCD financial assets will not be collected.

During three and six months ended June 30, 2021, First Busey incurred $2.7 million and $3.0 million, respectively, in pre-tax acquisition expenses related to the acquisition of CAC, comprised primarily of professional fees, compensation expense, and data processing expense.

Debt securities available for sale are not within the scope of CECL, however, the accounting for credit losses on these securities is affected by ASC 326-30. As of June 30, 2021, the Company’s debt security portfolio consisted of 1,249 securities, compared to 1,114 securities as of December 31, 2020. The number of debt securities in the investment portfolio in an unrealized loss position as of June 30, 2021, was 252, representing an unrealized loss of 1.02% of the aggregate fair value, compared to 23 securities as of December 31, 2020, representing an unrealized loss of 0.30% of the aggregate fair value. Unrealized losses related to changes in market interest rates and market conditions that do not represent credit-related impairments. Furthermore, the Company does not intend to sell such securities and it is more likely than not that the Company will recover the amortized cost prior to being required to sell the debt securities. Full

collection of the amounts due according to the contractual terms of the debt securities is expected; therefore, the impairment related to noncredit factors is recognized in accumulated other comprehensive income (loss), net of applicable taxes. As of June 30, 2021, the Company did not hold general obligation bonds of any single issuer, the aggregate of which exceeded 10% of the Company’s stockholders’ equity.

Net accretable purchase accounting adjustments included in the balances above reduced loans by $11.5 million as of June 30, 2021, and $10.9 million as of December 31, 2020. The June 30, 2021, commercial balance includes loans originated under PPP with an amortized cost of $390.4 million, compared to $446.4 million in loans originated under PPP included in the December 31, 2020, balance.

During the three and six months ended June 30, 2021, the Company purchased retail real estate loans totaling $32.2 million, compared to no retail real estate loan purchases during the three months ended June 30, 2020, and $43.9 million of retail real estate loan purchases in the six months ended June 30, 2020.

The Company utilizes a loan grading scale to assign a risk grade to all of its loans. A description of the general characteristics of each grade is as follows:

● Pass – This category includes loans that are all considered acceptable credits, ranging from investment or near investment grade, to loans made to borrowers who exhibit credit fundamentals that meet or exceed industry standards.

● Watch – This category includes loans that warrant a higher than average level of monitoring to ensure that weaknesses do not cause the inability of the credit to perform as expected. These loans are not necessarily a problem due to other inherent strengths of the credit, such as guarantor strength, but have above average concern and monitoring.

● Special mention – This category is for “Other Assets Specially Mentioned” loans that have potential weaknesses, which may, if not checked or corrected, weaken the asset or inadequately protect the Company’s credit position at some future date.

● Substandard – This category includes “Substandard” loans, determined in accordance with regulatory guidelines, for which the accrual of interest has not been stopped. Assets so classified must have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

● Substandard non-accrual – This category includes loans that have all the characteristics of a “Substandard” loan with additional factors that make collection in full highly questionable and improbable. Such loans are placed on non-accrual status and may be dependent on collateral with a value that is difficult to determine.

All loans are graded at their inception. Commercial lending relationships that are $1.0 million or less are usually processed through an expedited underwriting process. Most commercial loans greater than $1.0 million are included in a portfolio review at least annually. Commercial loans greater than $0.35 million that have a grading of special mention or worse are typically reviewed on a quarterly basis. Interim reviews may take place if circumstances of the borrower warrant a more frequent review. GSB’s policies are similar in nature to Busey Bank’s policies and the Company is migrating such loan production and grading toward the Busey Bank policies.

Total past due and non-accrual loans	$	6,794	$	784	$	1,371	$	22,930

Gross interest income recorded on 90+ day past due loans and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms was $0.4 million for the three months ended June 30, 2021 and 2020. Gross interest income recorded on 90+ day past due loans and that would have been recorded on non-accrual loans if they had been accruing interest in accordance with their original terms was $0.9 million for the six months ended June 30, 2021 and 2020. The amount of interest collected on those loans and recognized on a cash basis that was included in interest income was insignificant for the three and six months ended June 30, 2021 and 2020.

A summary of TDR loans is as follows (dollars in thousands):

	As of
	June 30,		December 31,
	2021		2020
Performing TDR loans:
In compliance with modified terms	$	2,518	$	3,814
30 – 89 days past due		—		15
Non-performing TDR loans		1,314		1,249
Total TDR loans	$	3,832	$	5,078

We did not newly classify any loans as performing TDRs during the three or six months ended June 30, 2021. Loans newly classified as performing TDRs during the three and six months ended June 30, 2020, included one retail real estate loan for $0.2 million for payment modification.

During the six months ended June 30, 2021, one commercial loan for $0.5 million was newly classified as a non-performing TDR for payment and rate modifications. This loan had been non-accrual since the second quarter of 2020. Also, during the six months ended June 30, 2021, one retail real estate loan for $0.1 million that had been a performing TDR for longer than 12 months, with a rate modification, became non-performing. During the six months ended June 30, 2020, three commercial loans for $0.5 million and one commercial real estate loan for $0.7 million were newly classified as non-performing TDRs for payment and rate modifications. These loans had been non-accrual since 2019.

There were no TDRs that were entered into during the last 12 months that were subsequently classified as non-performing and had payment defaults (a default occurs when a loan is 90 days or more past due or transferred to non-accrual) during the three and six months ended June 30, 2021 or 2020.

Gross interest income that would have been recorded in the three and six months ended June 30, 2021 and 2020 if TDRs had performed in accordance with their original terms compared with their modified terms was insignificant.

Modified loans with payment deferrals that fall under the CARES Act or revised Interagency Statement that suspended requirements under GAAP related to TDR classification are not included in the Company’s TDR totals.

As of June 30, 2021, the Company had $0.2 million of residential real estate in the process of foreclosure. The Company follows FHFA guidelines on single-family foreclosures and real estate owned evictions on portfolio loans, as well as all COVID-19 related state foreclosure and eviction orders. The existing moratoriums on single-family foreclosures expired on July 31, 2021; however, moratoriums on single-family real estate owned evictions have been extended until September 30, 2021.

The following tables provide details of loans evaluated individually, segregated by category. The Company evaluates loans with disparate risk characteristics on an individual basis. The unpaid contractual principal balance represents the customer outstanding balance excluding any partial charge-offs. Amortized cost represents customer balances net of any partial charge-offs recognized on the loan. Average amortized cost is calculated using the most recent four quarters (dollars in thousands):

Management's evaluation as to the ultimate collectability of loans includes estimates regarding future cash flows from operations and the value of property, real and personal, pledged as collateral. These estimates are affected by changing economic conditions and the economic prospects of borrowers. Collateral dependent loans are loans in which repayment is expected to be provided solely by the underlying collateral and there are no other available and reliable sources of repayment. Loans are written down to the lower of cost or fair value of underlying collateral, less estimated costs to sell. As of June 30, 2021, there were $17.2 million of collateral dependent loans secured by real estate or business assets.

Management estimates the ACL balance using relevant available information from internal and external sources relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. The cumulative loss rate used as the basis for the estimate of credit losses is comprised of the Company’s historical loss experience beginning in 2010. As of June 30, 2021, the Company expects the markets in which it operates to experience continued economic uncertainty around the levels of delinquencies over the next 12 months. Management adjusted the historical loss experience for these expectations with an immediate reversion to historical loss rate beyond this forecast period. PPP loans were excluded from the ACL calculation as they are 100% government guaranteed.

The following tables detail activity in the ACL. Allocation of a portion of the ACL to one category does not preclude its availability to absorb losses in other categories (dollars in thousands):

Note 6: Borrowings

Securities sold under agreements to repurchase, which are classified as secured borrowings, generally mature daily. Securities sold under agreements to repurchase are reflected at the amount of cash received in connection with the transaction. The underlying securities are held by the Company’s safekeeping agent. The Company may be required to provide additional collateral based on fluctuations in the fair value of the underlying securities. Securities sold under agreements to repurchase were as follows (dollars in thousands):

	As of
	June 30,			December 31,

On May 28, 2021, the Company entered into a Second Amended and Restated Credit Agreement, pursuant to which the Company has 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 one-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.

On May 25, 2017, the Company 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, the Company 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 three-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 the Company.

On June 1, 2020, the Company 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 the Company.

Regulatory Capital

Note 7: Regulatory Capital

The Company and its subsidiary banks are subject to various regulatory capital requirements administered by federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory – and possibly additional discretionary – actions by regulators that, if undertaken, could have a direct material effect on the Company's consolidated financial statements. Capital amounts and classification also are subject to qualitative judgments by regulators about components, risk weightings, and other factors.

Banking regulations identify five capital categories for insured depository institutions: well capitalized, adequately capitalized, undercapitalized, significantly undercapitalized, and critically undercapitalized. As of June 30, 2021, and December 31, 2020, all capital ratios of the Company and its subsidiary banks exceeded the well capitalized levels under the applicable regulatory capital adequacy guidelines. Management believes that no events or changes have occurred subsequent to June 30, 2021, that would change this designation.

On March 27, 2020, the FDIC and other federal banking agencies published an interim final rule that provides those banking organizations adopting CECL during 2020 with the option to delay for two years the estimated impact of CECL on regulatory capital and to phase in the aggregate impact of the deferral on regulatory capital over a subsequent three-year period. On August 26, 2020, the CECL final rule was finalized and was substantially similar to the interim final rule. Under this final rule, because the Company has elected to use the deferral option, the regulatory capital impact of our transition adjustments recorded on January 1, 2020, from the adoption of CECL will be deferred for two years, until January 1, 2022. In addition, 25 percent of the ongoing impact of CECL on our ACL, retained earnings, and average total consolidated assets from January 1, 2020, through the end of the two-year deferral period, each as reported for regulatory capital purposes, will be added to the deferred transition amounts (“adjusted transition amounts”) and deferred for the two-year period. At the conclusion of the two-year period the adjusted transition amounts will be phased-in for regulatory capital purposes at a rate of 25 percent per year, with the phased-in amounts included in regulatory capital at the beginning of each year. GSB adopted CECL as of the acquisition date, and based on the timing of the acquisition, GSB is not eligible for this deferral option.

The following tables summarize regulatory capital requirements applicable to the holding company its subsidiary banks (dollars in thousands):

In July 2013, U.S. federal banking authorities approved the Basel III Rule for strengthening international capital standards. The Basel III Rule introduced a capital conservation buffer, composed entirely of Common Equity Tier 1 Capital, which is added to the minimum risk-weighted asset ratios. The capital conservation buffer is not a minimum capital requirement; however, banking institutions with a ratio of Common Equity Tier 1 to risk-weighted assets below the capital conservation buffer will face constraints on dividends, equity repurchases, and discretionary bonus payments based on the amount of the shortfall. In order to refrain from restrictions on dividends, equity repurchases, and discretionary bonus payments, banking institutions must maintain minimum ratios of (i) total capital to risk-weighted

assets of at least 10.50%, (ii) Tier 1 Capital to risk-weighted assets of at least 8.50%, and (iii) Common Equity Tier 1 to risk-weighted assets of at least 7.00%.

Stock-based Compensation

Stock-based Compensation

Note 8: Stock-Based Compensation

Under the terms of the 2020 Equity Plan, the Company has granted restricted stock units, deferred stock units and performance-based restricted stock unit awards. The Company grants restricted stock units to members of management periodically throughout the year. Each restricted stock unit is equivalent to one share of the Company’s common stock. These units have requisite service periods ranging from one to five years, subject to accelerated vesting upon eligible retirement from the Company. Recipients earn quarterly dividend equivalents on their respective units which entitle the recipients to additional units. Therefore, dividends earned each quarter compound based upon the updated unit balances.

The Company grants deferred stock units, which are restricted stock units with a deferred settlement date, to its directors and advisory directors. Each deferred stock unit is equivalent to one share of the Company’s common stock. Deferred stock units vest over a one-year period following the grant date. These units generally are subject to the same terms as restricted stock units under the 2020 Equity Plan, except that, following vesting, settlement occurs within 30 days following the earlier of separation from the board or a change in control of the Company. After vesting and prior to delivery, these units will continue to earn dividend equivalents.

The Company also grants performance-based restricted stock unit awards to members of management periodically throughout the year. Each performance-based restricted stock unit is equivalent to one share of the Company’s common stock. The number of units that ultimately vest will be determined based on the achievement of the market or other performance goals, subject to accelerated service-based vesting conditions upon eligible retirement from the Company.

The Company has outstanding stock options assumed from acquisitions.

Upon vesting/delivery, shares are expected (though not required) to be issued from treasury.

Derivative Financial Instruments

Derivative Financial Instruments

Note 10: Derivative Financial Instruments

The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. Additionally, the Company enters into derivative financial instruments, including interest rate lock commitments issued to residential loan customers for loans that will be held for sale, forward sales commitments to sell residential mortgage loans to investors, and interest rate swaps with customers and other third parties. See “Note 11: Fair Value Measurements” for further discussion of the fair value measurement of such derivatives.

Interest Rate Swaps Designated as Cash Flow Hedges

The Company entered into derivative instruments designated as cash flow hedges. For a derivative instrument that is designated and qualifies as a cash flow hedge, the change in fair value of the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The change in fair value of components excluded from the assessment of effectiveness are recognized in current earnings.

Interest rate swaps with notional amounts totaling $70.0 million as of June 30, 2021, and December 31, 2020, were designated as cash flow hedges to hedge the risk of variability in cash flows (future interest payments) attributable to changes in the contractually specified 3-month LIBOR benchmark interest rate on the Company’s junior subordinated debt owed to unconsolidated trusts and were determined to be highly effective during the period. The gross aggregate fair value of the swaps of $2.0 million as of June 30, 2021, and $3.1 million as of December 31, 2020, is recorded in other liabilities in the unaudited Consolidated Balance Sheets, with changes in fair value recorded net of tax in other comprehensive income (loss). The Company expects the hedges to remain highly effective during the remaining terms of the swaps.

A summary of the interest-rate swaps designated as cash flow hedges is presented below (dollars in thousands):

	As of
	June 30,			December 31,
	2021			2020
Notional amount	$	70,000		$	70,000
Weighted average fixed pay rates		1.80	%		1.80	%
Weighted average variable 3-month LIBOR receive rates		0.12	%		0.22	%
Weighted average maturity, in years		2.36	yrs		2.85	yrs
Unrealized gains (losses), net of tax	$	(1,438)		$	(2,184)

Interest expense recorded on these swap transactions was $0.3 million and $0.6 million during the three and six months ended June 30, 2021, respectively. The Company expects $0.3 million of the unrealized loss to be reclassified from OCI to interest expense during the next three months. This reclassified amount could differ from amounts actually recognized due to changes in interest rates, hedge de-designations, and the addition of other hedges subsequent to June 30, 2021.

The following table reflects the net gains (losses) recorded in accumulated other comprehensive income (loss) and the unaudited Consolidated Statements of Income relating to cash flow derivative instruments for the periods presented (dollars in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,

Interest rate contracts
Gain (loss) recognized in OCI, net of tax	$	(69)	$	(10)	$	341	$	(2,247)

Net change in unrealized gains (losses) on cash flow hedges	$	137	$	(149)	$	746	$	(2,397)

The Company pledged $2.1 million in cash to secure its obligation under these contracts as of June 30, 2021, compared to $3.2 million pledged as of December 31, 2020.

Interest Rate Lock Commitments

Interest rate lock commitments that meet the definition of derivative financial instruments under ASC Topic 815, Derivatives and Hedging, are carried at their fair values in other assets or other liabilities in the unaudited consolidated financial statements, with changes in the fair values of the corresponding derivative financial assets or liabilities recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Forward Sales Commitments

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

Amounts and fair values of mortgage banking derivatives included in the unaudited Consolidated Balance Sheets are summarized as follows (dollars in thousands):

		As of June 30, 2021				As of December 31, 2020
		Notional		Fair		Notional		Fair

Net gains (losses) relating to these derivative instruments are summarized as follows for the periods presented (dollars in thousands):

		Three Months Ended June 30,				Six Months Ended June 30,
	Location	2021		2020		2021		2020

Net gains (losses)		$	(865)	$	(2,565)	$	(1,213)	$	(4,763)

The impact of the net gains or losses on derivative financial instruments related to interest rate lock commitments issued to residential loan customers for loans that will be held for sale and forward sales commitments to sell residential mortgage loans to loan investors are almost entirely offset by a corresponding change in the fair value of loans held for sale.

Interest Rate Swaps Not Designated as Hedges

The Company may offer derivative contracts to its customers in connection with their risk management needs. The Company manages the risk associated with these contracts by entering into equal and offsetting derivative agreements with a third-party dealer. These contracts support variable rate, commercial loan relationships totaling $408.5 million and $395.0 million as of June 30, 2021, and December 31, 2020, respectively. These derivatives generally worked together as an economic interest rate hedge, but the Company did not designate them for hedge accounting treatment. Consequently, changes in fair value of the corresponding derivative financial asset or liability were recorded as either a charge or credit to current earnings during the period in which the changes occurred.

Amounts and fair values of derivative assets and liabilities related to customer interest rate swaps recorded in the unaudited Consolidated Balance Sheets are summarized as follows (dollars in thousands):

Fair Value Measurements

Fair Value Measurements

Note 11: Fair Value Measurements

The fair value of an asset or liability is the price that would be received by selling that asset or paid in transferring that liability (exit price) in an orderly transaction occurring in the principal market (or most advantageous market in the absence of a principal market) for such asset or liability. ASC Topic 820, Fair Value Measurement, establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

● Level 1 Inputs – Unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date.

● Level 2 Inputs – Inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly. These might include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability (such as interest rates, volatilities, prepayment speeds, credit risks, etc.) or inputs that are derived principally from or corroborated by market data by correlation or other means.

● Level 3 Inputs – Unobservable inputs for determining the fair values of assets or liabilities that reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the assets or liabilities.

A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to those Company assets and liabilities that are carried at fair value.

In general, fair value is based upon quoted market prices, when available. If such quoted market prices are not available, fair values are measured utilizing independent valuation techniques of identical or similar securities for which significant assumptions are derived primarily from or corroborated by observable data. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value. These adjustments may include amounts to reflect, among other things, counterparty credit quality and the company's creditworthiness as well as unobservable parameters. Any such valuation adjustments are applied consistently over time. While management believes the Company's valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date.

Debt Securities Available for Sale

Debt securities classified as available for sale are reported at fair value utilizing Level 2 measurements. The Company obtains fair value measurements from an independent pricing service. The independent pricing service utilizes evaluated pricing models that vary by asset class and incorporate available trade, bid, and other market information. Because

many fixed income securities do not trade on a daily basis, the independent pricing service applies available information, focusing on observable market data such as benchmark curves, benchmarking of like securities, sector groupings, and matrix pricing to prepare evaluations.

The independent pricing service uses model processes, such as the Option Adjusted Spread model, to assess interest rate impact and develop prepayment scenarios. Models and processes take into account market conventions. For each asset class, a team of evaluators gathers information from market sources and integrates relevant credit information, perceived market movements, and sector news into the evaluated pricing applications and models.

Market inputs that the independent pricing service normally seeks for evaluations of securities, listed in approximate order of priority, include: benchmark yields, reported trades, broker/dealer quotes, issuer spreads, two-sided markets, benchmark securities, bids, offers, and reference data including market research publications. The independent pricing service also monitors market indicators, industry, and economic events. For certain security types, additional inputs may be used or some of the market inputs may not be applicable. Evaluators may prioritize inputs differently on any given day for any security based on market conditions, and not all inputs listed are available for use in the evaluation process for each security evaluation on a given day. Because the data utilized was observable, the securities have been classified as Level 2.

Equity Securities

Equity securities are reported at fair value utilizing Level 1 or Level 2 measurements. As applicable, for mutual funds, unadjusted quoted prices in active markets for identical assets are utilized to determine fair value at the measurement date and are classified as Level 1. For stock, quoted prices for identical or similar assets in markets that are not active are utilized and classified as Level 2.

Loans Held for Sale

Loans held for sale are reported at fair value utilizing Level 2 measurements. The fair value of the mortgage loans held for sale are measured using observable quoted market or contract prices or market price equivalents and are classified as Level 2.

Derivative Assets and Derivative Liabilities

Derivative assets and derivative liabilities are reported at fair value utilizing Level 2 measurements. Fair values of derivative assets and liabilities are determined based on prices that are obtained from a third-party which uses observable market inputs. Derivative assets and liabilities are classified as Level 2.

The following tables summarize financial assets and financial liabilities measured at fair value on a recurring basis as of June 30, 2021, and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis; that is, the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment).

Loans Evaluated Individually

The Company does not record portfolio loans at fair value on a recurring basis. However, periodically, a loan is evaluated individually and is reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. If the collateral value is not sufficient, a specific reserve is recorded. Collateral values are estimated using a combination of observable inputs, including recent appraisals, and unobservable inputs based on customized discounting criteria. Due to the significance of unobservable inputs, fair values of individually evaluated collateral dependent loans have been classified as Level 3.

OREO

Non-financial assets measured at fair value include OREO (upon initial recognition or subsequent impairment). OREO properties are measured using a combination of observable inputs, including recent appraisals, and unobservable inputs. Due to the significance of unobservable inputs, all OREO fair values have been classified as Level 3.

Bank Property Held for Sale

Bank property held for sale represents certain banking center office buildings which the Company has closed and consolidated with other existing banking centers. Bank property held for sale is measured at the lower of amortized cost or fair value less estimated costs to sell. Fair values were based upon discounted appraisals or real estate listing prices.

Due to the significance of unobservable inputs, fair values of all bank property held for sale have been classified as Level 3.

The following tables summarize assets and liabilities measured at fair value on a non-recurring basis as of June 30, 2021 and December 31, 2020, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value (dollars in thousands):

Earnings Per Share

Note 12: Earnings Per Common Share

Basic earnings per share is computed by dividing net income for the period by the weighted average number of common shares outstanding, which include deferred stock units that are vested but not delivered. Diluted earnings per common share is computed using the treasury stock method and reflects the potential dilution that could occur if the Company’s outstanding stock options and warrants were exercised and restricted stock units were vested.

Earnings per common share have been computed as follows (dollars in thousands, except per share amounts):

	Three Months Ended June 30,				Six Months Ended June 30,

The Wealth Management operating segment provides a full range of asset management, investment, brokerage, fiduciary, philanthropic advisory, tax preparation, and farm management services to individuals, businesses, and foundations. Wealth Management services for Busey Bank and GSB are aggregated into the Wealth Management operating segment as they have similar operations and activities.

The Company’s three operating segments are strategic business units that are separately managed as they offer different products and services and have different marketing strategies. The “other” category consists of the Parent Company, First Busey Risk Management, and the elimination of intercompany transactions.

The segment financial information provided below has been derived from information used by management to monitor and manage the financial performance of the Company. The accounting policies of the three segments are the same as those described in the summary of significant accounting policies in “Note 1.

Basis of Financial Statement Presentation

Basis of Financial Statement Presentation

These unaudited consolidated financial statements and related notes should be read in conjunction with the audited consolidated financial statements included in our 2020 Annual Report. These interim unaudited consolidated financial statements serve to update our 2020 Annual Report and may not include all information and notes necessary to constitute a complete set of financial statements.

We prepared these unaudited consolidated financial statements in conformity with GAAP. We have eliminated intercompany accounts and transactions. We have also reclassified certain prior year amounts to conform to the current period presentation. These reclassifications did not have a material impact on our consolidated financial condition or results of operations.

In our opinion, the unaudited consolidated financial statements reflect all normal, recurring adjustments needed to present fairly our results for the interim periods. The results of operations for interim periods are not necessarily indicative of the results that may be expected for the full year or any other interim period.

COVID-19

COVID-19

First Busey has continued to operate as an essential community resource during these challenging and unprecedented times. Federal bank regulatory agencies, along with their state counterparts, have issued a steady stream of guidance responding to the COVID-19 pandemic and have taken a number of steps to help banks navigate the pandemic and mitigate its impact.

The Company remains vigilant as the negative impacts of COVID-19, such as further margin compression and a deterioration in asset quality, could impact future quarters.

As part of the CARES Act, Congress appropriated approximately $349 billion for the creation of the PPP and then authorized a second phase for an additional $310 billion in PPP loans. The program provided payroll assistance for the nation’s nearly 30 million small businesses—and select nonprofits—in the form of 100% government-guaranteed low-interest loans from the SBA. On December 27, 2020, the Economic Aid Act extended the authority to make PPP loans through March 31, 2021, and revised certain PPP requirements. On March 30, 2021, the President signed the PPP Extension Act of 2021, which extended the PPP application deadline to May 31, 2021, or until funding was exhausted, which occurred on May 28, 2021. First Busey served as a bridge for these programs, actively helping existing and new business clients sign up for this important financial resource.

The following table summarizes First Busey’s PPP loans as of June 30, 2021, (dollars in thousands):

Use of Estimates

Use of Estimates

In preparing the accompanying unaudited consolidated financial statements in conformity with GAAP, the Company’s management is required to make estimates and assumptions that affect the amounts reported in the financial statements and the disclosures provided. Actual results could differ from those estimates. Material estimates which are particularly susceptible to significant change in the near term relate to the fair value of investment securities available for sale, fair value of assets acquired and liabilities assumed in business combinations, goodwill, income taxes, and the determination of the ACL.

Subsequent Events

Subsequent Events

The Company has evaluated subsequent events for potential recognition and/or disclosure through the date the unaudited consolidated financial statements included in this Quarterly Report were issued. On July 27, 2021, the Company announced its Personal Banking Transformation Plan which includes plans to close and consolidate 15 Busey Bank banking centers. In addition, the Company announced plans to consolidate two GSB banking centers, with the banking centers in connection with the integration of the acquisition. Each of these banking center closures is expected to occur in the fourth quarter of 2021. There were no other significant subsequent events for the quarter ended June 30, 2021, through the filing date of these unaudited consolidated financial statements.
