BANCFIRST CORPORATION

NOTES TO CONSOLIDATE D FINANCIAL STATEMENTS

(Unaudited)

(1) DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

The accounting and reporting policies of BancFirst Corporation and its subsidiaries (the “Company”) conform to accounting principles generally accepted in the United States of America (U.S. GAAP) and general practice within the banking industry. A summary of significant accounting policies can be found in Note (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of BancFirst Corporation, Council Oak Partners, LLC, BancFirst Insurance Services, Inc., Pegasus Bank ("Pegasus"), Worthington National Bank ("Worthington") and BancFirst and its subsidiaries. The principal operating subsidiaries of BancFirst are Council Oak Investment Corporation, Council Oak Real Estate, Inc., BFTower, LLC, BFC-PNC LLC, and BancFirst Agency, Inc. All significant intercompany accounts and transactions have been eliminated. Assets held in a fiduciary or agency capacity are not assets of the Company and, accordingly, are not included in the unaudited interim consolidated financial statements.

The accompanying unaudited interim consolidated financial statements and notes are presented in accordance with U.S. GAAP for interim financial information and the instructions for Form 10-Q adopted by the Securities and Exchange Commission (“SEC”). The information contained in the financial statements and footnotes included in BancFirst Corporation’s Annual Report on Form 10-K for the year ended December 31, 2021, should be referred to in connection with these unaudited interim consolidated financial statements. Operating results for the interim periods disclosed herein are not necessarily indicative of the results that may be expected for a full year or any future period.

The unaudited interim consolidated financial statements contained herein reflect all adjustments, which are, in the opinion of management, necessary to provide a fair statement of the financial position and results of operations of the Company for the interim periods presented. All such adjustments are of a normal and recurring nature.

Reclassifications

Certain items in prior financial statements have been reclassified to conform to the current presentation. Such reclassifications had no effect on previously reported cash flows, stockholders’ equity or comprehensive income.

Use of Estimates in the Preparation of Financial Statements

The preparation of financial statements in conformity with accounting principles generally accepted in the United States inherently involves the use of estimates and assumptions that affect the amounts reported in the financial statements and the related disclosures. These estimates relate principally to the determination of the allowance for credit losses, income taxes, the fair value of financial instruments and the valuation of intangibles. Such estimates and assumptions may change over time and actual amounts realized may differ from those reported.

Recent Accounting Pronouncements

Standards Not Yet Adopted:

In March 2022, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2022-02, “Financial Instruments – Credit Losses (Topic 326).” ASU 2022-02 eliminates the TDR recognition and measurement guidance and, instead, requires that the Company evaluate, based on the accounting for loan modifications, whether the modification represents a new loan or a continuation of an existing loan. The Company has the option to apply a modified retrospective transition method, resulting in a cumulative-effect adjustment to retained earnings when adopted. In addition, the update requires that the Company disclose current-period write-offs by year of origination for financing receivables. The current-period write-off amendment should be applied prospectively. The amendments are effective for annual periods beginning after December 15, 2022, including interim periods within those annual periods. Early adoption is permitted; however the Company expects to adopt ASU 2022-02 on January 1, 2023. ASU No. 2022-02 is not expected to have a significant impact on the Company’s financial statements.

(2) RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS

On February 8, 2022, BancFirst Corporation acquired Worthington for an aggregate cash purchase price of $77.7 million. Worthington is chartered and regulated by the Office of the Comptroller of the Currency (OCC) with one banking location in Arlington, Texas, one in Colleyville, Texas and two in Fort Worth, Texas. At acquisition, Worthington had approximately $484 million in total assets, $257 million in loans and $430 million in deposits. Worthington will continue to operate as “Worthington National Bank” under a separate OCC charter and remain a separate subsidiary of BancFirst Corporation governed by its existing board of directors. BancFirst Corporation intends to provide an appropriate amount of capital or other support to increase Worthington’s ability to approve larger loans and allow Worthington to continue to grow earning assets. As a result of the acquisition, the Company recorded a core deposit intangible of approximately $8.7 million and goodwill of approximately $26.6 million. These fair value estimates are considered preliminary and are subject to change for up to one year after the closing date of the acquisition as additional information becomes available. The effect of this acquisition was included in the consolidated financial statements of the Company from the date of acquisition forward. The acquisition did not have a material effect on the Company’s consolidated financial statements.

On June 17, 2021, the Company completed a private placement, under Regulation D of the Securities Act of 1933, of $60 million aggregate principal amount of 3.50% Fixed-to-Floating Rate Subordinated Notes due 2036 (the “Subordinated Notes”) to various institutional accredited investors. See Note (7) of the Notes to Consolidated Financial Statements for a complete discussion of the Company’s subordinated debt.

On May 20, 2021, the Company purchased approximately $284 million in total assets, which included approximately $195 million in loans, and assumed approximately $256 million in deposits and certain other obligations, from The First National Bank and Trust Company of Vinita, Oklahoma for a purchase price of approximately $21 million. The Company recorded a bargain purchase gain related to this purchase of approximately $4.8 million, which was included in other noninterest income on the statement of comprehensive income and in other operating activities on the statement of cash flow during the second quarter of 2021. The bargain purchase gain is a noncash item on the statement of cash flow. In addition, the Company recorded expenses related to this purchase of approximately $4.8 million, which were included in noninterest expense during the second quarter of 2021. As a result of the purchase, the Company recorded a core deposit intangible of approximately $1.7 million. The effect of this purchase was included in the consolidated financial statement of the Company from the date of purchase forward. The purchase did not have a material effect on the Company’s consolidated financial statements. The First National Bank and Trust Company of Vinita was a nationally chartered bank with two banking locations in Vinita and Grove, Oklahoma.

On January 22, 2021, the Company sold approximately $21 million in loans and approximately $38 million in deposits from its Hugo, Oklahoma branch to AmeriState Bank in Atoka, Oklahoma. The Company recorded a gain on the transaction of $2.5 million, which is included in noninterest income in the first quarter of 2021.

During the three months ended March 31, 2022, the Company sold $226 million of debt securities with an average yield of 0.16%, which were subsequently reinvested in $220 million of debt securities with an average yield of 1.86%. The Company used specific identification to reclassify the unrealized loss in other comprehensive income to a realized loss, as shown in the consolidated statements of comprehensive income. There were no sales of debt securities and therefore no proceeds from sales or realized securities gains or losses on available for sale debt securities for the three months ended March 31, 2021.

Realized gains/losses on debt and equity securities are reported as securities transactions within the noninterest income section of the consolidated statement of comprehensive income.

The Company has the ability and intent to hold the debt securities classified as held for investment until they mature, at which time the Company will receive full value for the debt securities. Furthermore, as of March 31, 2022 and December 31, 2021, the Company also had the ability and intent to hold the debt securities classified as available for sale for a period of time sufficient for a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying debt securities were purchased. The fair value of those debt securities having unrealized losses is expected to recover as the securities approach their maturity date or repricing date, or if market yields for such investments decline. The Company has no intent or requirement to sell before the recovery of the unrealized loss; therefore, no impairment loss was realized in the Company’s consolidated statement of comprehensive income.

Other loans. Other loans consist of loans approved by the Small Business Administration (“SBA”), which include loans funded through the Paycheck Protection Program (“PPP”). Since PPP loans are fully guaranteed by the SBA, there is no expected credit loss related to these loans. In April 2020, the Company began originating loans to qualified small businesses under the PPP administered by the SBA. The Company had processing fees, which were recognized as interest income related to the PPP loans totaling $1.7 milli on and $9.8 million during the three months ended March 31, 2022 and 2021, respectively.

The Company's loans are currently 84% held by BancFirst and 16% held by Pegasus and Worthington. In addition, approximately 64% of the Company's loans are secured by real estate. Credit risk on loans is managed through limits on amounts loaned to individual and related borrowers, underwriting standards and loan monitoring procedures. The amounts and types of collateral obtained, if any, to secure loans are based upon the Company’s underwriting standards and management’s credit evaluation. Collateral varies, but may include real estate, equipment, accounts receivable, inventory, livestock and securities. The Company’s interest in collateral is secured through filing mortgages and liens, and in some cases, by possession of the collateral.

Accounting policies related to appraisals, and charge-offs are disclosed in Note (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Credit Quality Indicators

The Company considers credit quality indicators to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical credit loss experience and economic conditions. These indicators are reviewed and updated regularly throughout the year. An internal risk grading system is used to indicate the credit risk of loans. The loan grades used by the Company are for internal risk identification purposes and do not directly correlate to regulatory classification categories or any financial reporting definitions. The general characteristics of the risk grades and the table summarizing the Company’s gross loans held for investment by year of origination and internally assigned credit grades as of December 31, 2021, are disclosed in Note (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

The Company’s revolving loans that are converted to term loans are not material and therefore have not been presented.

The following table summarizes the Company’s gross loans held for investment by year of origination and internally assigned credit grades :

Allowance for Credit Losses Methodology

The Company determines its provision for credit losses and allowance for credit losses using the expected loss methodology that is referred to as the CECL model. The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist.

The increase in allowance for credit loss during 2022 was primarily related to the purchase of loans without credit deterioration during the quarter. The decrease in the allowance for credit loss during 2021 was driven by a reversal of a pandemic-related provision during 2021 based on sustained improvements in the economy, both nationally and in the Company's markets, which reduced the amount of expected credit loss within the loan portfolio. This reduction was partially offset by additional allowance for credit loss required by newly acquired loans.

The following table details activity in the allowance for credit losses on loans for the period presented. Allocation of a portion of the allowance to one category of loans does not preclude its availability to absorb losses in other categories.

|  | Allowance for Credit Losses |
|  | Balance at beginning of period |  |  | Initial allowance on loans purchased with credit deterioration |  |  | Charge- offs |  |  | Recoveries |  |  | Net charge-offs |  |  | Provision for /(benefit from) credit losses on loans |  |  | Balance at end of period |

(7) SUBORDINATED DEBT

In January 2004, the Company established BFC Capital Trust II (“BFC II”), a trust formed under the Delaware Business Trust Act. The Company owns all of the common securities of BFC II. In February 2004, BFC II issued $25 million of aggregate liquidation amount of 7.20% Cumulative Trust Preferred Securities (the “Cumulative Trust Preferred Securities”) to other investors. In March 2004, BFC II issued an additional $1 million in Cumulative Trust Preferred Securities through the execution of an over-allotment option. The proceeds from the sale of the Cumulative Trust Preferred Securities and the common securities of BFC II were invested in $26.8 million of 7.20% Junior Subordinated Debentures of the Company. Interest payments on the $26.8 million of 7.20% Junior Subordinated Debentures are payable January 15, April 15, July 15 and October 15 of each year. Such interest payments may be deferred for up to twenty consecutive quarters. The stated maturity date of the $26.8 million of 7.20% Junior Subordinated Debentures is March 31, 2034, but they are subject to mandatory redemption pursuant to optional prepayment terms. The Cumulative Trust Preferred Securities represent an undivided interest in the $26.8 million of 7.20% Junior Subordinated Debentures and are guaranteed by the Company. During any deferral period or during any event of default, the Company may not declare or pay any dividends on any of its capital stock. The Cumulative Trust Preferred Securities were callable at par, in whole or in part, after March 31, 2009.

On June 17, 2021, the Company completed a private placement, under Regulation D of the Securities Act of 1933, of $60 million aggregate principal amount of 3.50% Fixed-to-Floating Rate Subordinated Notes due 2036 (the “Subordinated Notes”) to various institutional accredited investors. The sale of the Subordinated Notes was pursuant to a Subordinated Note Purchase Agreement entered into with each of the investors. The Subordinated Notes have been structured to qualify as Tier 2 capital under bank regulatory guidelines. The net proceeds to the Company from the sale of the Subordinated Notes were approximately $59.15 million after deducting commissions and offering expenses of $850,000. The Company used the proceeds from the sale of the Subordinated Notes for general corporate purposes. The Subordinated Notes will initially bear interest at a fixed rate of 3.50% per annum, from and including June 17, 2021 to but excluding June 30, 2031, payable semi-annually in arrears on June 30 and December 31 of each year, commencing December

18

31, 2021. Then, from and including June 30, 2031, to but excluding the maturity date, the Subordinated Notes will bear interest at a floating rate equal to the benchmark (initially, three-month term SOFR), reset quarterly, plus a spread of 229 basis points, payable quarterly in arrears on March 31, June 30, September 30 and December 31 of each year. The Subordinated Notes mature on June 30, 2036.

The Company may, at its option, beginning with the interest payment date of June 30, 2031, and on any scheduled interest payment date thereafter, redeem the Subordinated Notes, in whole or in part. In addition, the Company may redeem all, but not less than all, of the Subordinated Notes at any time upon the occurrence of a “Tier 2 Capital Event,” a “Tax Event” or an “Investment Company Event” (each as defined in the Subordinated Notes). Any such redemption is subject to obtaining the prior approval of the Board of Governors of the Federal Reserve System (or its designee). The redemption price with respect to any such redemption will be equal to 100% of the principal amount of the Subordinated Note, or portion thereof, to be redeemed, plus accrued but unpaid interest, if any, thereon to, but excluding, the redemption date.

(8) STOCK-BASED COMPENSATION

The Company has had a nonqualified incentive stock option plan, the BancFirst Corporation Stock Option Plan (the “Employee Plan”), since May 1986. At March 31, 2022, there were 116,000 shares available for future grants. The Employee Plan will terminate on December 31, 2024, if not extended. The options vest and are exercisable beginning four years from the date of grant at the rate of 25% per year for four years. Options expire no later than the end of fifteen years from the date of grant. The option price must be no less than 100% of the fair value of the stock relating to such option at the date of grant.

The Company has had the BancFirst Corporation Non-Employee Directors’ Stock Option Plan (the “Non-Employee Directors’ Plan”) since June 1999. Each non-employee director is granted an option for 10,000 shares. At March 31, 2022, there were 40,000 shares available for future grants. The Non-Employee Directors’ Plan will terminate on December 31, 2024, if not extended. The options vest and are exercisable beginning one year from the date of grant at the rate of 25% per year for four years, and expire no later than the end of fifteen years from the date of grant. The option price must be no less than 100% of the fair value of the stock relating to such option at the date of grant.

The Company currently uses newly issued shares for stock option exercises, but reserves the right to use shares purchased under the Company’s Stock Repurchase Program (the “SRP”) in the future.

Although not required or expected, the Company may settle some options in cash on a limited basis at the discretion of the Company. During the three months ended March 31, 2021, the Company had cash settlements for 121,330 shares for a total net cash settlement of options of $5.5 million that did not increase the outstanding shares of the Company.

The following table is a summary of the activity under both the Employee Plan and the Non-Employee Directors’ Plan:

The fair value of each option grant is estimated on the date of grant using the Black-Scholes option-pricing model and is based on certain assumptions including risk-free rate of return, dividend yield, stock price volatility and the expected term. The fair value of each option is expensed over its vesting period.

The following table is a summary of the Company’s recorded stock-based compensation expense:

|  | Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
|  | (Dollars in thousands) |
Stock-based compensation expense |  | $ | 458 |  |  | $ | 576 |
Tax benefit |  |  | 110 |  |  |  | 147 |
Stock-based compensation expense, net of tax |  | $ | 348 |  |  | $ | 429 |

The Company will continue to amortize the unearned stock-based compensation expense over the remaining vesting period of approximately seven years. The following table shows the unearned stock-based compensation expense:

|  | March 31, 2022 |
|  | (Dollars in thousands) |
Unearned stock-based compensation expense |  | $ | 7,780 |

The following table shows the assumptions used for computing stock-based compensation expense under the fair value method on options granted during the periods presented:

|  | Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
Weighted average grant-date fair value per share of options granted |  | $ | 26.21 |  |  | $ | 23.80 |
Risk-free interest rate |  | 1.75 to 2.14% |  |  | 1.34 to 1.64% |
Dividend yield |  | 2.00% |  |  | 2.00% |
Stock price volatility |  | 34.61 to 34.69% |  |  | 35.55 to 35.73% |
Expected term |  | 10 Yrs |  |  | 10 Yrs |

The risk-free interest rate is determined by reference to the spot zero-coupon rate for the U.S. Treasury security with a maturity similar to the expected term of the options. The dividend yield is the expected yield for the expected term. The stock price volatility is estimated from the recent historical volatility of the Company’s stock. The expected term is estimated from the historical option exercise experience. The Company accounts for forfeitures as they occur.

The Company has had the BancFirst Corporation Directors’ Deferred Stock Compensation Plan (the “Deferred Stock Compensation Plan”) since May 1999. As of March 31, 2022, there are 31,914 shares available for future issuance under the Deferred Stock Compensation Plan. The Deferred Stock Compensation Plan will terminate on December 31, 2024, if not extended. Under the plan, directors and members of the community advisory boards of the Company and its subsidiaries may defer up to 100% of their board fees. They are credited for each deferral with a number of stock units based on the current market price of the Company’s stock, which accumulate in an account until such time as the director or community board member terminates serving as a board member. Shares of common stock of the Company are then distributed to the terminating director or community board member based upon the number of stock units accumulated in his or her account. There were 6,177 and 2,161 shares of common stock distributed from the Deferred Stock Compensation Plan during the three months ended March 31, 2022 and 2021, respectively.

A summary of the accumulated stock units is as follows:

|  | March 31, |  |  | December 31, |
|  | 2022 |  |  | 2021 |
Accumulated stock units |  |  | 148,788 |  |  |  | 152,754 |
Average price |  | $ | 31.82 |  |  | $ | 30.86 |

(9) STOCKHOLDERS’ EQUITY

In November 1999, the Company adopted the SRP. The SRP may be used as a means to increase earnings per share and return on equity. In addition, the SRP may be used to purchase treasury stock for the exercise of stock options or for distributions under the Deferred Stock Compensation Plan, to provide liquidity for optionees to dispose of stock from exercises of their stock options and to provide liquidity for stockholders wishing to sell their stock. All shares repurchased under the SRP have been retired and not held as treasury stock. The timing, price and amount of stock repurchases under the SRP may be determined by management and approved by the Company’s Executive Committee. During September 2021, the SRP was amended to permit the repurchase of an additional 650,000 shares.

The following table is a summary of the shares under the program:

|  | Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
Number of shares repurchased |  |  | — |  |  |  | — |
Average price of shares repurchased |  | $ | — |  |  | $ | — |

BancFirst Corporation, BancFirst, Pegasus and Worthington are subject to risk-based capital guidelines issued by the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation (“FDIC”). These guidelines are used to evaluate capital adequacy and involve both quantitative and qualitative evaluations of BancFirst Corporation’s, BancFirst’s, Pegasus’s and Worthington's assets, liabilities and certain off-balance-sheet items calculated under regulatory practices. Failure to meet the minimum capital requirements can initiate certain mandatory or discretionary actions by the regulatory agencies that could have a direct material effect on the Company’s financial statements. The Company believes that as of March 31, 2022, BancFirst Corporation, BancFirst, Pegasus and Worthington met all capital adequacy requirements to which they are subject. The actual and required capital amounts and ratios are shown in the following table:

|  |  |  |  |  |  | Required |  |  |  | To Be Well

As of March 31, 2022, the most recent notifications from the Federal Reserve Bank of Kansas City, the FDIC and the Comptroller of the Currency, categorized BancFirst, Pegasus and Worthington as “well capitalized” under the prompt corrective action provisions. The Common Equity Tier 1 Capital of BancFirst Corporation, BancFirst, Pegasus and Worthington includes common stock and related paid-in capital and retained earnings. In connection with the adoption of the Basel III Capital Rules, the election was made to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1 Capital. Common Equity Tier 1 Capital for BancFirst Corporation, BancFirst, Pegasus and Worthington is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities. The Company’s trust preferred securities have continued to be included in Tier 1 capital, as the Company’s total assets do not exceed $15 billion. There are no conditions or events since the most recent notifications to BancFirst Corporation, BancFirst, Pegasus and Worthington of their capital category that management believes would materially change their category under capital requirements existing as of the report date.

On June 17, 2021, the Company completed a private placement, under Regulation D of the Securities Act of 1933, of $60 million aggregate principal amount of Subordinated Notes. The Subordinated Notes have been structured to qualify as Tier 2 capital under bank regulatory guidelines.

In April 2020, the Company began originating loans to qualified small businesses under the PPP administered by the SBA. Federal bank regulatory agencies have issued an interim final rule that permits banks to neutralize the regulatory capital effects of participating in the Paycheck Protection Program Lending Facility (the “PPP Facility”) and clarify that PPP loans have a zero percent risk weight under applicable risk-based capital rules. Specifically, a bank may exclude all PPP loans pledged as collateral to the PPP Facility from its average total consolidated assets for the purposes of calculating its leverage ratio, while PPP loans that are not pledged as collateral to the PPP Facility are included. The PPP loans the Company originated in 2021 and 2020 are included in the calculation of the Company’s leverage ratio as of March 31, 2022 as the Company did not utilize the PPP Facility for funding purposes.

(11) FAIR VALUE MEASUREMENTS

Accounting standards define fair value as the price that would be received to sell an asset or the price paid to transfer a liability in the principal or most advantageous market available to the entity in an orderly transaction between market participants on the measurement date.

FASB Accounting Standards Codification (“ASC”) Topic 820 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 to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.
•
Level 2 Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset and liability, either directly or indirectly, for substantially the full term of the financial instrument.
•
Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. This category includes certain collaterally dependent loans, repossessed assets, other real estate owned, goodwill and other intangible assets.

Financial Assets and Financial Liabilities Measured at Fair Value on a Recurring Basis

A description of the valuation methodologies and key inputs used to measure financial assets and financial liabilities at fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. These valuation methodologies were applied to the following categories of the Company’s financial assets and financial liabilities.

Debt Securities Available for Sale

Debt securities classified as available for sale are reported at fair value. U.S. Treasuries are valued using Level 1 inputs. Other debt securities available for sale including U.S. federal agencies, registered mortgage backed debt securities and state and political subdivisions are valued using prices from an independent pricing service utilizing Level 2 data. The fair value measurements consider 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 bond’s terms and conditions, among other things. The Company also invests in private label mortgage backed debt securities for which observable information is not readily available. These debt securities are reported at fair value utilizing Level 3 inputs. For these debt securities, management determines the fair value based on replacement cost, the income approach or information provided by outside consultants or lead investors. Discount rates are primarily based on reference to interest rate spreads on comparable debt securities of similar duration and credit rating as determined by the nationally recognized rating agencies adjusted for a lack of trading volume. Significant unobservable inputs are developed by investment securities professionals involved in the active trading of similar debt securities.

The Company reviews the prices for Level 1 and Level 2 debt securities supplied by the independent pricing service for reasonableness and to ensure such prices are aligned with traditional pricing matrices. In general, the Company does not purchase investment portfolio debt securities that are esoteric or that have complicated structures. The Company’s portfolio primarily consists of traditional investments including U.S. Treasury obligations, federal agency mortgage pass-through debt securities, general obligation municipal bonds and a small amount of municipal revenue bonds. Pricing for such instruments is fairly generic and is easily obtained. For in-state bond issues that have relatively low issue sizes and liquidity, the Company utilizes the same parameters for pricing mentioned in the preceding paragraph adjusted for the specific issue. Periodically, the Company will validate prices supplied by the independent pricing service by comparison to prices obtained from third party sources.

Derivatives

Derivatives are reported at fair value utilizing Level 2 inputs. The Company obtains dealer and market quotations to value its oil and gas swaps and options. The Company utilizes dealer quotes and observable market data inputs to substantiate internal valuation models.

The changes in Level 3 assets measured at estimated fair value on a recurring basis during the periods presented were as follows:

|  | Three Months Ended March 31, |  |  | Twelve Months Ended December 31, |
|  | 2022 |  |  | 2021 |
|  | (Dollars in thousands) |
Balance at the beginning of the year |  | $ | 320 |  |  | $ | 12,869 |
Transfers to level 2 |  |  | — |  |  |  | (12,714 | )
Purchases |  |  | — |  |  |  | 240 |
Settlements |  |  | (80 | ) |  |  | (75 | )
Balance at the end of the period |  | $ | 240 |  |  | $ | 320 |

The Company’s policy is to recognize transfers in and transfers out of Levels 1, 2 and 3 as of the end of the reporting period. During the three months ended March 31, 2022, the Company did not transfer any debt securities. During the year ended December 31, 2021, the Company transferred debt securities from Level 3 to Level 2 due to a review of the pricing models that determined some asset backed debt securities to be Level 2.

Financial Assets and Financial Liabilities Measured at Fair Value on a Nonrecurring Basis

Certain financial assets and financial liabilities are measured at fair value on a nonrecurring 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). These financial assets and financial liabilities are reported at fair value utilizing Level 3 inputs.

The Company invests in equity securities without readily determinable fair values and utilizes Level 3 inputs. These equity securities are reported at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The realized and unrealized gains and losses are reported as securities transactions in the noninterest income section of the consolidated statements of comprehensive income.

Collateral dependent loans are reported at the fair value of the underlying collateral if repayment is dependent on liquidation of the collateral. When the Company determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit

24

losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs as appropriate. In no case does the fair value of a collateral dependent loan exceed the fair value of the underlying collateral. The collateral dependent loans are adjusted to fair value through a specific allocation of the allowance for credit losses or a direct charge-down of the loan.

Repossessed assets, upon initial recognition, are measured and adjusted to fair value through a charge-off to the allowance for possible credit losses based upon the fair value of the repossessed asset.

Other real estate owned is revalued at fair value subsequent to initial recognition, with any losses recognized in net expense from other real estate owned.

The following table summarizes assets measured at fair value on a nonrecurring basis during the period presented. The fair value represents end of period values, which approximate fair value measurements that occurred on various measurement dates throughout the period:

|  | Total Fair Value |

Estimated Fair Value of Financial Instruments

The Company is required under current authoritative accounting guidance to disclose the estimated fair value of their financial instruments that are not recorded at fair value. For the Company, as for most financial institutions, substantially all of its assets and liabilities are considered financial instruments. A financial instrument is defined as cash, evidence of an ownership interest in an entity or a contract that creates a contractual obligation or right to deliver or receive cash or another financial instrument from a second entity. The following methods and assumptions were used to estimate the fair value of each class of financial instruments:

Cash and Cash Equivalents Include: Cash and Due from Banks and Interest-Bearing Deposits with Banks

The carrying amount of these short-term instruments is based on a reasonable estimate of fair value.

Federal Funds Sold

The carrying amount of these short-term instruments is a reasonable estimate of fair value.

Debt Securities Held for Investment

For debt securities held for investment, which are generally traded in secondary markets, fair values are based on quoted market prices or dealer quotes, if available. If a quoted market price is not available, fair value is estimated using quoted market prices for similar debt securities making adjustments for credit or liquidity if applicable.

Loans Held For Sale

The Company originates mortgage loans to be sold. At the time of origination, the acquiring bank has already been determined and the terms of the loan, including interest rate, have already been set by the acquiring bank, allowing the Company to originate the loan at fair value. Mortgage loans are generally sold within 30 days of origination. Loans held for sale are valued using Level 2 inputs. Gains or losses recognized upon the sale of the loans are determined on a specific identification basis.

Loans

To determine the fair value of loans, the Company uses an exit price calculation, which takes into account factors such as liquidity, credit and the nonperformance risk of loans. For certain homogeneous categories of loans, such as some residential mortgages, fair

25

values are estimated using the quoted market prices for securities backed by similar loans, adjusted for differences in loan characteristics. The fair values of other types of loans are estimated by discounting the future cash flows using the current rates at which similar loans would be made to borrowers with similar credit ratings and for the same remaining maturities.

Deposits

The fair values of transaction and savings accounts are the amounts payable on demand at the reporting date. The fair values of fixed-maturity certificates of deposit are estimated using the rates currently offered for deposits of similar remaining maturities.

Short-Term Borrowings

The amounts payable on these short-term instruments are reasonable estimates of fair value.

Subordinated Debt

The fair values of subordinated debt are estimated using the rates that would be charged for subordinated debt of similar remaining maturities.

Loan Commitments and Letters of Credit

The fair values of commitments are estimated using the fees currently charged to enter into similar agreements, taking into account the terms of the agreements. The fair values of letters of credit are based on fees currently charged for similar agreements.

The estimated fair values of the Company’s financial instruments that are reported at amortized cost in the Company’s consolidated balance sheets, segregated by the level of valuation inputs within the fair value hierarchy utilized to measure fair value, are as follows:

|  | March 31, |  |  | December 31, |

Non-financial Assets and Non-financial Liabilities Measured at Fair Value

The Company has no non-financial assets or non-financial liabilities measured at fair value on a recurring basis. Certain non-financial assets and non-financial liabilities measured at fair value on a nonrecurring basis include intangible assets and other non-financial long-lived assets measured at fair value and adjusted for impairment. These items are evaluated at least annually for impairment. The overall levels of non-financial assets and non-financial liabilities measured at fair value on a nonrecurring basis were no t considered to be significant to the Company at March 31, 2022 or December 31, 2021.

26

(12) DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into oil and gas swaps and options contracts to accommodate the business needs of its customers. Upon the origination of an oil or gas swap or option contract with a customer, to mitigate the exposure to fluctuations in oil and gas prices, the Company simultaneously enters into an offsetting contract with a counterparty. These derivatives are not designated as hedged instruments and are recorded on the Company's consolidated balance sheet at fair value and are included in other assets. The Company's derivative financial instruments require a daily margin to be posted, which fluctuates with oil and gas prices. These margins have increased during 2022 due to the current increase in oil and gas prices and customer activity. These margins are included in other assets totaling $84.6 million at March 31, 2022 and $14.3 million at December 31, 2022.

The Company utilizes dealer quotations and observable market data inputs to substantiate internal valuation models. The notional amounts and estimated fair values of oil and gas derivative positions outstanding are presented in the following table:

|  |  |  | March 31, 2022 |  |  | December 31, 2021 |
Oil and Natural Gas Swaps and Options |  | Notional Units |  | Notional Amount |  |  | Estimated Fair Value |  |  | Notional Amount |  |  | Estimated Fair Value |

Derivative liabilities |  | MMBTUs |  |  | (24,462 | ) |  |  | (21,768 | ) |  |  | (19,752 | ) |  |  | (2,108 | )

Derivative assets |  | Other assets |  |  |  |  |  | 62,701 |  |  |  |  |  |  | 8,946 |
Derivative liabilities |  | Other liabilities |  |  |  |  |  | (61,651 | ) |  |  |  |  |  | (8,237 | )

The following table is a summary of the Company's recognized income related to the activity, which was included in other noninterest income:

|  | Three Months Ended March 31, |
|  | 2022 |  |  | 2021 |
|  | (Dollars in thousands) |
Derivative income |  | $ | 159 |  |  | $ | 2 |

The Company's credit exposure on oil and gas swaps and options varies based on the current market prices of oil and natural gas. Other than credit risk, changes in the fair value of customer positions will be offset by equal and opposite changes in the counterparty positions. The net positive fair value of the contracts represents the profit derived from the activity and is unaffected by the market price movements. The Company's share of total profit is approximately 35%.

Customer credit exposure is managed by strict position limits and is primarily offset by first liens on production while the remainder is offset by cash. Counterparty credit exposure is managed by selecting highly rated counterparties (rated A- or better by Standard and Poor's) and monitoring market information.

The Company's net credit exposure relating to oil and gas swaps and options with bank counterparties was zero as of both March 31, 2022 and December 31, 2021.

Balance Sheet Offsetting

Derivatives may be eligible for offset in the consolidated balance sheet and/or subject to master netting arrangements. The Company's derivative transactions with upstream financial institution counterparties and bank customers are generally executed under International Swaps and Derivative Association ("ISDA") master agreements, which include "right of set-off" provisions. In such cases there is generally a legally enforceable right to offset recognized amounts and there may be an intention to settle such amounts on a net basis. Nonetheless, the Company does not generally offset such financial instruments for financial reporting purposes.

SUMMARY

The Company’s net income for the first quarter of 2022 was $35.9 million, compared to $42.5 million for the first quarter of 2021. Diluted net income per common share was $1.08 and $1.27 for the first quarter of 2022 and 2021, respectively. The Company’s net interest income for the first quarter of 2022 decreased to $75.5 million, compared to $77.2 million for the first quarter of 2021. The decrease was due to the decline of PPP fee income of approximately $8.1 million, partially offset by the increase in interest income on debt securities of $2.0 million, an increase of $1.2 million related to interest-bearing deposits at the Federal Reserve and $1.7 million in net interest income related to the Worthington acquisition. The net interest margin for the first quarter was 2.78%, compared to 3.36% a year ago. The decrease in margin was due to lower PPP fees earned during the quarter and an increase in cash held at the Federal Reserve. For the first quarter of 2022 a provision of $2.9 million was recorded, which was substantially related to acquired loans during the quarter, compared to no provision for credit losses recorded for March 31, 2021. Noninterest income for the first quarter of 2022 totaled $43.7 million, compared to $39.9 million for the first quarter of 2021. The increase in noninterest income was mostly attributable to $4.9 million of income resulting from the application of equity method accounting related to an equity interest received in the process of a loan collection, along with a $2.3 million increase in income from service charges on deposits and $1.4 million increase in insurance commissions. The increase in non-interest income was partially offset by a loss of $4.0 million on bonds resulting from the sale of $226 million of low yielding debt securities, which were subsequently reinvested in higher yielding debt securities and a $2.6 million gain on sale of other assets in the first quarter last year. Noninterest expense for the first quarter of 2022 increased to $72.5 million compared to $65.0 million for the first quarter of 2021 because of the increase in salaries and employee benefits of approximately $4.4 million and other expenses related to the Worthington acquisition. The Company’s effective tax rate was 17.8% for the first quarter of 2022 compared to 18.5% for the first quarter of 2021. The lower effective tax rate was driven by the exercising of stock options during the quarter and a lower state income tax rate.

At March 31, 2022, the Company’s total assets were $12.6 billion, an increase of $3.2 billion from December 31, 2021. Debt securities of $1.2 billion were up $677.2 million from December 31, 2021. Loans totaled $6.5 billion, an increase of $310.3 million from December 31, 2021. Loans increased $257.4 million due to the acquisition of Worthington. At March 31, 2022, the balance of the PPP loans was $30.6 million, compared to $80.4 million at December 31, 2021. Deposits totaled $11.3 billion, an increase of $3.2 billion from the December 31, 2021 total. The increase in assets and deposits from December 31, 2021 was primarily related to the return of off-balance sheet sweep accounts related to the Company’s year-end sweep program. Off-balance sheet sweep accounts totaled $2.9 billion at March 31, 2022 compared to $5.1 billion at December 31, 2021. The Company’s total stockholders’ equity at March 31, 2022 was $1.2 billion, a decrease of $3.9 million over December 31, 2021. The decrease in stockholders equity was due to unrealized losses included in other comprehensive income.

Nonaccrual loans represented 0.27% of total loans at March 31, 2022, down from 0.34% at December 31, 2021. The allowance for credit losses to total loans was 1.34% at March 31, 2022 compared to 1.36% at December 31, 2021, and the allowance for credit losses to nonaccrual loans was approximately 500% at March 31, 2022 compared to 402% at December 31, 2021. At March 31, 2022, the Company’s nonaccrual loans were $17.5 million compared to $20.9 million at year-end 2021.

Net Interest Income

For the three months ended March 31, 2022, net interest income, which is the Company’s principal source of operating revenue, decreased $1.7 million or 2.2% compared to the three months ended March 31, 2021. The decrease was due to the decline of PPP fee income of approximately $8.1 million, partially offset by the increase in interest income on debt securities of $2.0 million, an increase of $1.2 million related to interest-bearing deposits at the Federal Reserve and $1.7 million in net interest income related to the Worthington acquisition. Net interest margin is the ratio of taxable-equivalent net interest income to average earning assets for the period. As shown in the preceding table, the Company’s net interest margin for the first quarter of 2022 decreased compared to the first quarter of 2021. The decrease in margin was due to lower PPP fees earned during the quarter and an increase in cash held at the Federal Reserve.

The Company’s net interest income and net interest margin have been impacted by the decreases in interest rates stemming from the Federal Reserve's response to the COVID-19 pandemic. However, the Company's expectation is that interest rates will increase during the year.

Provision for Credit Losses

For the first quarter of 2022, the Company recorded a provision for credit losses of $2.9 million, which was substantially related to acquired loans during the quarter, compared to no provision for credit losses recorded for the first quarter of 2021. The Company establishes an allowance as an estimate of the expected credit losses in the loan portfolio at the balance sheet date. Management believes the allowance for credit losses is appropriate based upon management’s best estimate of expected losses within the existing loan portfolio. Should any of the factors considered by management in evaluating the appropriate level of the allowance for credit losses change, the Company’s estimate of expected credit losses could also change, which could affect the amount of future provisions for credit losses. Net loan charge-offs were $289,000 for the first quarter of 2022, compared to net loan charge-offs of $506,000 for the first quarter of 2021. The rate of net charge-offs to average total loans, as presented in the preceding table, continues to be at a low level.

32

Noninterest Income

Noninterest income, as presented in the preceding table, increased by $3.7 million for the first quarter of 2022 compared to the first quarter of 2021. The increase in noninterest income was mostly attributable to $4.9 million of income resulting from the application of equity method accounting related to an equity interest received in the process of a loan collection, along with a $2.3 million increase in income from service charges on deposits and $1.4 million increase in insurance commissions. The increase in non-interest income was partially offset by a loss of $4.0 million on bonds resulting from the sale of $226 million of low yielding debt securities, which were subsequently reinvested in higher yielding debt securities, and a $2.6 million gain on sale of other assets in the first quarter last year.

Noninterest income included non-sufficient funds fees totaling $6.5 million and $5.5 million for the three months ended March 31, 2022 and 2021, respectively. This represents 15.0% and 13.8% of the Company’s noninterest income for the respective periods. In addition, the Company had debit card interchange fees totaling $11.7 million and $10.7 million during the three months ended March 31, 2022 and 2021, respectively. This represents 26.7% of the Company’s noninterest income for both periods.

The Company is subject to political pressures that could limit its ability to charge for non-sufficient funds ("NSF") and overdraft fees. It is expected that recent changes to the Company's rates charged on NSF and overdraft fees will lower annual pretax income by $6 to $7 million.

It is probable the Company will exceed $10 billion in total assets at December 31, 2022. Pursuant to the Durbin Amendment of the Dodd-Frank Act, based on current run rates, this would trigger an approximate reduction of annual pretax income from debit card interchange fees of between $22 to $24 million beginning July 1, 2023.

Noninterest Expense

Noninterest expense, as presented in the preceding table, increased by $7.5 million for first quarter of 2022 compared to the first quarter of 2021. The increase in noninterest expenses was due to the increase in salaries and employee benefits of approximately $4.4 million and other expenses related to the Worthington acquisition.

Income Taxes

The Company’s effective tax rate was 17.8% for the first quarter of 2022, compared to 18.5% for the first quarter of 2021. The lower effective tax rate was driven by the exercising of stock options during the first quarter of 2022 and a lower state income tax rate. The reasons for the difference between the Company’s effective tax rate and the federal statutory rate were tax-exempt income, nondeductible amortization, federal and state tax credits and state tax expense.

Cash and Interest-Bearing Deposits with Banks

The aggregate of cash and due from banks and interest-bearing deposits with banks increased by $2.0 billion or 99.6% to $4.1 billion, from December 31, 2021 to March 31, 2022. The increase was primarily related to the return of off-balance sheet sweep accounts related to the Company’s year-end sweep program, which was partially off-set by the purchase of higher yielding bonds described below.

Securities

At March 31, 2022, total debt securities increased $677.2 million, or 126.7% compared to December 31, 2021. The size of the Company’s securities portfolio is determined by the Company’s liquidity and asset/liability management. The net unrealized loss on debt securities available for sale, before taxes, was $38.7 million at March 31, 2022, compared to a net unrealized gain of $2.8 million at December 31, 2021. These unrealized losses and gains are included in the Company’s stockholders’ equity as accumulated other comprehensive income, net of income tax, in the amounts of a loss of $29.5 million at March 31, 2022 and a gain of $2.2 million at December 31, 2021. During the quarter ended March 31, 2022, the Company had a loss of $4.0 million on bonds resulting from the sale

34

of $226 million of debt securities with an average yield of 0.16%, which were subsequently reinvested in $220 million of debt securities with an average yield of 1.86%. On January 10, 2022, the Company purchased United States Treasury Notes of $600 million par value with an average yield of 1.42% and an average maturity of 53 months.

See Note (3) of the Notes to Consolidated Financial Statements for disclosures regarding the Company’s Securities.

Loans

At March 31, 2022, total loans increased $310.3 million or 5.0% compared to December 31, 2021. Loans increased $257.4 million due to the acquisition of Worthington. At March 31, 2022, the balance of total PPP loans was $30.6 million, net of unamortized processing fees of approximately $394,000 compared to $80.4 million, net of unamortized processing fees of $2.0 million at December 31, 2021.

See Note (4) of the Notes to Consolidated Financial Statements for disclosures regarding the Company’s loan portfolio segments.

Allowance for Credit Losses

The increase in the allowance for credit loss during 2022 was substantially related to the additional allowance for credit loss required by newly acquired loans. The decrease in the allowance for credit loss during 2021 was driven by a reversal of a pandemic-related provision during 2021 based on sustained improvements in the economy, both nationally and in the Company's markets, which reduced the amount of expected credit loss within the loan portfolio. This reduction was partially offset by additional allowance for credit loss required by newly acquired loans.

Nonperforming and Restructured Assets

At March 31, 2022, nonperforming and restructured assets decreased $3.2 million to $65.9 million compared to December 31, 2021. The Company’s level of nonperforming and restructured assets has continued to be relatively low, equating to 0.52% of total assets at March 31, 2022 and 0.73% of total assets at December 31, 2021.

Nonaccrual loans totaled $17.5 million at March 31, 2022, compared to $20.9 million at December 31, 2021. The Company’s nonaccrual loans decreased $3.4 million from December 31, 2021 due to resolutions of several loans. The Company’s nonaccrual loans are primarily commercial and agricultural non-real estate and farmland. Nonaccrual loans negatively impact the Company’s net interest margin. A loan is placed on nonaccrual status when, in the opinion of management, the future collectability of both interest and principal is in serious doubt. Interest income is not recognized until the principal balance is fully collected. However, if the full collection of the remaining principal balance is not in doubt, interest income is recognized on certain of these loans on a cash basis. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $376,000 for the three months ended March 31, 2022 and $521,000 for the three months ended March 31, 2021. Only a small amount of this interest is expected to be ultimately collected. Approximately $3.4 million of nonaccrual loans were guaranteed by government agencies at March 31, 2022.

Restructured loans totaled $2.3 million at March 31, 2022 compared to $3.7 million at December 31, 2021. The Company charges interest on principal balances outstanding during deferral periods. As a result, the current and future financial effects of the recorded balance of loans considered to be troubled debt restructurings whose terms were modified during the period were not considered to be material.

The classification of a loan as nonperforming does not necessarily indicate that loan principal and interest will ultimately be uncollectible; although, in an economic downturn, the Company’s experience has been that the level of collections declines. The above normal risk associated with nonperforming loans has been considered in the determination of the allowance for credit losses. At March 31, 2022, the allowance for credit losses as a percentage of nonperforming and restructured loans was 333.51%, compared to 284.33%, at December 31, 2021. The level of nonperforming loans and credit losses could rise over time as a result of adverse economic conditions.

Other real estate owned (OREO) and repossessed assets totaled $39.7 million at March 31, 2022, compared to $39.6 million at December 31, 2021. Other real estate owned consists of properties acquired through foreclosure proceedings or acceptance of a deed in lieu of foreclosure and premises held for sale. As of both March 31, 2022 and December 31, 2021, other real estate owned included a commercial real estate property recorded at approximately $29.5 million. The Company's rental income from OREO was approximately $2.8 million for the three months ended March 31, 2022 compared to approximately $2.4 million for the three months ended March 31, 2021. In addition, the Company's OREO holding expense was approximately $2.5 million for the three months ended March 31, 2022 compared to approximately $1.5 million for the three months ended March 31, 2021. Other real estate owned and repossessed assets are carried at the lower of the book values of the related loans or fair values based upon appraisals, less estimated costs to sell. Write-downs arising at the time of reclassification of such properties from loans to other real estate owned are charged directly to the allowance for

35

credit losses. Any losses on bank premises designated to be sold are charged to operating expense at the time of transfer from premises to other real estate owned. Decreases in values of properties subsequent to their classification as other real estate owned are charged to operating expense.

Intangible Assets, Goodwill and Other Assets

Identifiable intangible assets and goodwill totaled $202.0 million and $167.5 million at March 31, 2022 and December 31, 2021, respectively. The increase in goodwill and intangible assets was due the acquisition of Worthington on February 8, 2022, which added approximately $8.7 million of core deposit intangibles and approximately $26.6 million of goodwill. S ee Note (2) of the Notes to Consolidated Financial Statements for disclosure regarding the Company’s recent developments, including mergers and acquisitions.

Other assets includes the cash surrender value of key-man life insurance policies totaling $81.0 million at March 31, 2022 and $81.4 million at December 31, 2021.

The Company's derivative financial instruments are included in other assets and totaled $62.7 million at March 31, 2022 and $8.9 million at December 31, 2022. The derivative financial instruments have increased due to the increase in oil and gas prices and customer activity. The Company's derivative financial instruments require a daily margin to be posted, which fluctuates with oil and gas prices. These margins have increased during 2022 due to the current increase in oil and gas prices and customer activity. These margins are included in other assets totaling $84.6 million at March 31, 2022 and $14.3 million at December 31, 2022. S ee Note (12) of the Notes to Consolidated Financial Statements for a complete discussion of the Company’s derivative financial instruments.

Equity securities are reported in other assets on the balance sheet. The Company invests in equity securities without readily determinable fair values. These equity securities are reported at cost minus impairment, if any, plus or minus changes resulting from observable price changes in orderly transactions for the identical or a similar investment of the same issuer. The realized and unrealized gains and losses are reported as securities transactions in the noninterest income section of the consolidated statements of comprehensive income. The balance of equity securities was $10.2 million at March 31, 2022 and $10.6 million at December 31, 2021. The Company reviews its portfolio of equity securities for impairment at least quarterly.

Low Income Housing and New Market Tax Credit Investments

During 2022, there have not been any material changes in the Company’s low income housing tax credit investments and new market tax credit investments, which are included in other assets on the Company’s balance sheet. See Note (6) of the Notes to Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021, for disclosures regarding these investments.

Liquidity and Funding

The Company’s principal source of liquidity and funding is its broad deposit base generated from customer relationships. The availability of deposits is affected by economic conditions, competition with other financial institutions and alternative investments available to customers. Through interest rates paid, service charge levels and services offered, the Company can affect its level of deposits to a limited extent. The level and maturity of funding necessary to support the Company’s lending and investment functions is determined through the Company’s asset/liability management process. The Company currently does not rely heavily on long-term borrowings and does not utilize brokered CDs. The Company maintains federal funds lines of credit with other banks and could also utilize the sale of loans, securities and liquidation of other assets as sources of liquidity and funding.

There have not been any other material changes from the liquidity and funding discussion included in Management’s Discussion and Analysis in the Company’s Annual Report on Form 10-K for the year ended December 31, 2021.

Deposits

At March 31, 2022, deposits totaled $11.3 billion, an increase of $3.2 billion or 39.0% from the December 31, 2021 total. The increase in deposits was primarily related to the return of off-balance sheet sweep accounts related to the Company’s year-end sweep program. The Company’s core deposits provide it with a stable, low-cost funding source. The Company’s core deposits as a percentage of total deposits were 98.5% at March 31, 2022 and 98.2% at December 31, 2021. Noninterest-bearing deposits to total deposits were 46.4% at March 31, 2022, compared to 46.7% at December 31, 2021.

In addition, off-balance sheet sweep accounts totaled $2.9 billion at March 31, 2022 compared to $5.1 billion at December 31, 2021, which included a temporary sweep amount of approximately $2.3 billion. The year-end sweep program affected the balances of both assets and deposits.

Subordinated Debt

On June 17, 2021, the Company completed a private placement, under Regulation D of the Securities Act of 1933, of $60 million aggregate principal amount of 3.50% Fixed-to-Floating Rate Subordinated Notes due 2036 to various institutional accredited investors. See Note (7) of the Notes to Consolidated Financial Statements for a complete discussion of the Company’s subordinated debt.

Short-Term Borrowings

Short-term borrowings, consisting primarily of federal funds purchased and repurchase agreements are another source of funds for the Company. The level of these borrowings is determined by various factors, including customer demand and the Company’s ability to earn a favorable spread on the funds obtained. Short-term borrowings were $3.3 million at March 31, 2022. The Company did not have short-term borrowings at December 31, 2021.

Lines of Credit

BancFirst has a line of credit from the Federal Home Loan Bank (“FHLB”) of Topeka, Kansas to use for liquidity or to match-fund certain long-term fixed-rate loans. In addition, BancFirst has a $25.0 million line of credit with another financial institution that is an overnight federal funds facility. As of March 31, 2022 and December 31, 2021, BancFirst had no advances outstanding under either line of credit. Pegasus has a $20.0 million line of credit with another financial institution that is an overnight federal funds facility. As of March 31, 2022 and December 31, 2021, Pegasus had no advances outstanding under its line of credit. Worthington has an $8.5 million line of credit with another financial institution that is an overnight federal funds facility, and a line of credit from the FHLB of Dallas, Texas to use for liquidity or to match-fund certain long-term fixed rate loans. Worthington had no advances outstanding as of March 31, 2022 under either line of credit.

Capital Resources

Stockholders’ equity totaled $1.2 billion at both March 31, 2022 and December 31, 2021. In addition to net income of $35.9 million, other changes in stockholders’ equity during the three months ended March 31, 2022 included $3.1 million related to common stock issuances for stock option exercises and $458,000 related to stock-based compensation, that were partially offset by $11.8 million in dividends and a $31.7 million decrease in accumulated other comprehensive income. The Company’s leverage ratio and total risk-based capital ratios at March 31, 2022, were well in excess of the regulatory requirements.

See Note (9) of the Notes to Consolidated Financial Statements for a discussion of capital ratios and requirements.
