BANCFIRST CORPORATION

NOTES TO CONSOLIDATED 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, 2020.

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 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, 2020, 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.

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.

(2) RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS

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 $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 $21.0 million. The Company recorded a bargain purchase gain related to this purchase of approximately $6.0 million, which is included in other noninterest income on the statement of comprehensive income and other operating activities on the statement of cash flow. 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 $4.0 million, which are included in noninterest expense. As a result of the purchase, the Company recorded a core deposit intangible of approximately $1.9 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. The preliminary purchase price assessment remains an ongoing process and is subject to change for up to one year subsequent to the closing date.

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.

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. T he Company had processing fees, which were recognized as interest income related to the PPP loans totaling $11.9 million and $3.7 million during the three months ended June 30, 2021 and 2020, respectively and $21.7 million and $3.7 million during the six months ended June 30, 2021 and 2020, respectively.

BancFirst’s loans are mostly to customers within Oklahoma and approximately 56% of the 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.

Pegasus Bank’s loans are mostly to customers within Texas and approximately $297 million or 51% of the loans are secured by real estate at June 30, 2021. Pegasus Bank’s commercial and agricultural non-real estate loans were approximately $268 million at June 30, 2021 and approximately $262 million at December 31, 2020.

Due to the impacts of the COVID-19 pandemic, the Company had approximately $61.8 million in modified loans as of June 30, 2021 and $81.7 million in modified loans as of December 31, 2020, most of which were secured by commercial real estate. These modifications were undertaken in response to Section 4013 of the CARES Act and the regulatory intent outlined in the Interagency Statement on Loan Modifications by Financial Institutions Working with Customers Affected by the Coronavirus and to provide businesses financial flexibility until the economy has time to recover to a more normal level of activity. However, these modifications, which typically involve payment modifications and forbearance, also have the effect of delaying recognition of loans that may ultimately be permanently impaired. The timing and extent of such consequences are difficult to ascertain at this time and are dependent on the duration of the COVID-19 pandemic, the level and success of the government’s economic stimulus, and further regulatory guidance. These modified loans are included in Current Loans in the table above.

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. 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 our gross loans held for investment by year of origination and internally assigned credit grades as of December 31, 2020, are disclosed in Note (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

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

The following table summarizes our gross loans held for investment by year of origination and internally assigned credit grades as of June 30, 2021:

Allowance for Credit Losses Methodology

On January 1, 2020, the Company adopted ASC 326, which replaces the incurred loss methodology for determining its provision for credit losses and allowance for credit losses with an expected loss methodology that is referred to as the CECL model. Upon adoption, the allowance for credit losses was decreased by $3.2 million, with no impact to the consolidated statement of income.

The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist by identifying by portfolio segments, the applicable weighted average life and measuring the allowance for credit losses using the vintage loss analysis adjusted for qualitative factors. The weighted average lives of the Company’s loans segments are disclosed in Note (1) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

The decrease in the allowance for credit loss during the second quarter of 2021 was primarily driven by a reversal of provision during the quarter based on sustained improvements in the economy, both nationally and in Oklahoma, 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 purchased with credit deterioration.

(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 was approximately $59.15 million after deducting commissions and offering expenses of $850,000. The Company expects to use 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 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.

20

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 June 30, 2021, there were 275,000 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 June 30, 2021, there were 50,000 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 six months ended June 30, 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 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 June 30, |  |  | Six Months Ended June 30, |
|  | 2021 |  |  | 2020 |  |  | 2021 |  |  | 2020 |

Stock-based compensation expense |  | $ | 473 |  |  | $ | 406 |  |  | $ | 1,049 |  |  | $ | 832 |
Tax benefit |  |  | 114 |  |  |  | 103 |  |  |  | 252 |  |  |  | 212 |
Stock-based compensation expense, net of tax |  | $ | 359 |  |  | $ | 303 |  |  | $ | 797 |  |  | $ | 620 |

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:

|  | June 30, 2021 |
|  | (Dollars in thousands) |
Unearned stock-based compensation expense |  | $ | 5,417 |

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:

|  | Six Months Ended June 30, |
|  | 2021 |  |  | 2020 |
Weighted average grant-date fair value per share of options granted |  | $ | 23.74 |  |  | $ | 10.63 |
Risk-free interest rate |  | 1.34 to 1.74% |  |  | 0.66 to1.13% |
Dividend yield |  | 2.00% |  |  | 2.00% |
Stock price volatility |  | 35.55 to 36.01% |  |  | 22.84 to 33.56% |
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 June 30, 2021, there are 40,000 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 2,161 and 1,307 shares of common stock distributed from the Deferred Stock Compensation Plan during the six months ended June 30, 2021 and June 30, 2020, respectively.

A summary of the accumulated stock units is as follows:

|  | June 30, |  |  | December 31, |
|  | 2021 |  |  | 2020 |
Accumulated stock units |  |  | 150,118 |  |  |  | 148,278 |

(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.

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

|  | Six Months Ended June 30, |
|  | 2021 |  |  | 2020 |
Number of shares repurchased |  |  | — |  |  |  | 59,284 |

The Company, BancFirst and Pegasus Bank 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 the Company’s, BancFirst’s and Pegasus Bank’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. Management believes that as of June 30, 2021, the Company, BancFirst and Pegasus Bank met all capital adequacy requirements to which they are subject. The actual and required capital amounts and ratios are shown in the following table:

As of June 30, 2021, the most recent notification from the Federal Reserve Bank of Kansas City and the FDIC categorized BancFirst and Pegasus Bank as “well capitalized” under the prompt corrective action provisions. The Common Equity Tier 1 Capital of the Company, BancFirst and Pegasus Bank 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 the Company, BancFirst and Pegasus Bank is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities. The

23

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 notification of BancFirst and Pegasus Bank’s capital category that management believes would materially change its category under capital requirements existing as of the report date.

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 2020 and 2021 are included in the calculation of the Company’s leverage ratio as of June 30, 2021 as the Company did not utilize the PPP Facility for funding purposes.

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.

(1 1) | 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 management 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.

25

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.

The following table summarizes financial assets and financial liabilities measured at fair value on a recurring basis as of the periods presented, segregated by the level of the valuation inputs within the fair value hierarchy utilized to measure fair value:

|  | Level 1 Inputs |  |  | Level 2 Inputs |  |  | Level 3 Inputs |  |  | Total Fair Value |

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

|  | Six Months Ended June 30, |  |  | Twelve Months Ended December 31, |
|  | 2021 |  |  | 2020 |
|  | (Dollars in thousands) |
Balance at the beginning of the year |  | $ | 12,869 |  |  | $ | 12,714 |
Transfers (to)/from level 2 |  |  | (12,714 | ) |  |  | 1,643 |
Purchases |  |  | 240 |  |  |  | — |
Settlements |  |  | (75 | ) |  |  | (1,473 | )
Total unrealized losses |  |  | — |  |  |  | (15 | )
Balance at the end of the period |  | $ | 320 |  |  | $ | 12,869 |

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 six months ended June 30, 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. During the year ended December 31, 2020, the Company transferred debt securities from Level 2 to Level 3 due to a review of the pricing models that determined some state and political subdivisions bonds to be Level 3.

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

26

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 management 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 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:

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.

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. At December 31, 2020, the Company’s principal subsidiary bank, BancFirst, had approximately $21.6 million in loans held for sale at its Hugo, Oklahoma branch that were sold to AmeriState Bank in Atoka, Oklahoma in the first quarter of 2021.

27

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 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:

|  | June 30, |  |  | December 31, |

THE COVID-19 PANDEMIC

The COVID-19 pandemic and actions taken in response to it have negatively impacted the global economy and all financial markets since March 31, 2020. Although the Company is not able to estimate the impact of the COVID-19 pandemic and the resultant economic circumstances on a long-term basis at this time, the COVID-19 pandemic could materially affect the Company’s financial and operational results. The Company is closely monitoring its loan portfolio for effects related to COVID-19. See Item 1.A. Risk Factors in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020, for further discussion.

SUMMARY

The Company’s net income for the second quarter of 2021 was $48.2 million, compared to $20.7 million for the second quarter of 2020. Diluted net income per common share was $1.45 and $0.63 for the second quarter of 2021 and 2020, respectively. The Company recorded a net benefit from reversal of provisions for credit losses of $9.9 million for the second quarter of 2021, compared to a provision for credit losses of $19.3 million for the second quarter of 2020. Also included in noninterest income and noninterest expense were a purchase gain and acquisition related expenses from the purchase and assumption transaction with The First National Bank and Trust Company of Vinita, Oklahoma, which resulted in a net benefit of approximately $2.0 million.

Net income was $90.7 million, or $2.72 diluted earnings per share, for the six months ended June 30, 2021, compared to net income of $43.3 million, or $1.31 diluted earnings per share, for the six months ended June 30, 2020.

The Company’s net interest income for the second quarter of 2021 increased to $82.4 million, compared to $77.2 million for the second quarter of 2020, due primarily to $12.0 million in fee income from Paycheck Protection Program (PPP) loan forgiveness. The net interest margin for the quarter was 3.32%, compared to 3.54% a year ago. Noninterest income for the second quarter of 2021 totaled $44.6 million, compared to $32.1 million for the second quarter of 2020. The increase in noninterest income was primarily due to the previously discussed purchase gain associated with The First National Bank and Trust Company of Vinita, Oklahoma, $2.2 million in rental income from other real estate property, and a $2.7 million increase in income from debit card interchange fees, which were partially offset by a $1.5 million decrease in income from sweep fees. Noninterest expense for the second quarter of 2021 increased to $74.0 million, compared to $64.7 million for the second quarter of 2020, due to approximately $3.2 million related to other real estate property operating costs, the previously discussed acquisition related expenses and $1.3 million in net occupancy and depreciation primarily from the Company’s new corporate headquarters. The Company’s effective tax rate was 23.4% for the second quarter of 2021 compared to 18.1% for the second quarter of 2020.

At June 30, 2021, the Company’s total assets were $11.0 billion, an increase of $1.8 billion from December 31, 2020. Loans totaled $6.2 billion, a decrease of $241.0 million from December 31, 2020 due primarily to a net decrease of approximately $284 million in PPP loans and the sale of approximately $21 million of loans from the Company’s Hugo, Oklahoma branch along with pay downs on loans. The decrease in loans were partially offset by the Company’s purchase of approximately $195 million in loans, from the First National Bank and Trust Company of Vinita, Oklahoma. Deposits totaled $9.7 billion, an increase of $1.7 billion from the December 31, 2020 total. The increase in assets and deposits were primarily related to PPP and other government stimulus payments. At June 30, 2021, the Company had PPP loans held for investment of $368.6 million, net of unamortized processing fees of $16.6 million. The Company’s total stockholders’ equity at June 30, 2021 was $1.1 billion, an increase of $63.7 million over December 31, 2020. Off-balance sheet sweep accounts totaled $2.6 billion at June 30, 2021 compared to $2.8 billion at December 31, 2020.

Nonaccrual loans represent 0.48% of total loans at June 30, 2021, down from 0.58% at December 31, 2020. Net charge-offs for the quarter were 0.06% of average loans for the second quarter of 2021, compared to none in the second quarter of 2020. The allowance for credit losses to total loans was 1.35% at June 30, 2021 compared to 1.42% at December 31, 2020. The allowance for credit losses to nonaccrual loans was 281.73% at June 30, 2021 compared to 243.35% at December 31, 2020.

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.

Net Interest Income

For the three months ended June 30, 2021, net interest income, which is the Company’s principal source of operating revenue, increased $5.2 million or 6.7% compared to the three months ended June 30, 2020. Net interest income increased for the second quarter of 2021, due primarily to $12.0 million in fee income from PPP loan forgiveness. 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 second quarter of 2021 decreased compared to the second quarter of 2020, primarily due to the lower average rates on loans, securities and interest-bearing deposits with banks during the quarter.

Net interest income for the six months ended June 30, 2021 increased $8.3 million or 5.5% compared to the six months ended June 30, 2020. Net interest income increased for the six months ended June 30, 2021, due primarily to $21.7 million in fee income from PPP loan forgiveness and the drop in interest rates on deposits. As shown in the preceding table, the Company’s net interest margin for the six months ended June 30, 2021 decreased compared to the six months ended June 30, 2020, primarily due to the lower average rates on loans, securities and interest-bearing deposits with banks during the period.

The Company’s net interest income and net interest margin have been, and the Company currently expects them to continue to be, impacted by the decreases in market interest rates. The expectation is that interest rates will remain at these low levels for some period of time in light of the ongoing response in Federal Reserve policy driven by the economic disruption arising from the COVID-19 pandemic.

Benefit from and Provision for Credit Losses

For the second quarter of 2021, the Company recorded a net benefit from reversal of provisions for credit losses of $9.9 million, compared to a provision for credit losses of $19.3 million for the second quarter of 2020. The Company’s reversal of provision for the second quarter of 2021 was based on improvements in economic conditions and the Company’s outlook for certain economic indicators. The elevated provision during the second quarter of 2020 was based on the Company’s evaluation of the level of uncertainty and lack of clarity of the timing of an end to the COVID-19 pandemic, as well as the magnitude of the government’s stimulus response to it. The Company establishes an allowance as an estimate of the expected credit losses in the loan portfolio at the

34

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 $4.2 million for the second quarter of 20 2 1, compared to net loan recoveries of $87,000 for the second quarter of 2020. The rate of net charge-offs to average total loans, as presented in the preceding table, continues to be at a low level.

For the six months ended June 30, 2021, the Company recorded a net benefit from reversal of provisions for credit losses of $9.9 million compared to a provision for credit losses of $38.9 million for the six months ended June 30, 2020. Net loan charge-offs were $4.7, compared to $961,000 for the same period of the prior year.

Noninterest Income

Noninterest income, as presented in the preceding table, increased by $12.5 million for second quarter of 2021 compared to the second quarter of 2020. The increase in noninterest income was primarily due to a purchase gain of $6.0 million associated with The First National Bank and Trust Company of Vinita, Oklahoma, $2.2 million in rental income from other real estate property, and a $2.7 million increase in income from debit card interchange fees, which were partially offset by a $1.5 million decrease in income from sweep fees. In addition, the Company earned $2.1 million on the sale of loans for second quarter of 2021 compared to $1.6 million for second quarter of 2020. The income from sales of loans increased due to the increase in volume of mortgage loans originated because of record low mortgage rates.

Noninterest income included non-sufficient funds fees totaling $5.6 million and $5.0 million for the three month periods ended June 30, 2021 and 2020, respectively. This represents 12.6% and 15.6% of the Company’s noninterest income for the respective periods. In addition, the Company had debit card interchange fees totaling $11.9 million and $9.1 million during the three month periods ended June 30, 2021 and 2020, respectively. This represents 26.6% and 28.5% of the Company’s noninterest income for the respective periods. For the second quarter of 2021 compared to the second quarter of 2020, government assistance funds that flowed into the market, including PPP loans and stimulus payments to households, increased both customer liquidity and interchange volume resulting in higher debit card interchange fees.

Noninterest income increased by $17.3 million for the six months ended June 30, 2021 compared to the six months ended June 30, 2020. The increase in noninterest income was primarily due to a purchase gain of $6.0 million associated with The First National Bank and Trust Company of Vinita, Oklahoma, a gain from the sale of the Company’s Hugo, Oklahoma branch of $2.5 million and $4.6 million in rental income from other real estate property, which were partially offset by a $3.6 million decrease in income from sweep fees. In addition, the Company earned $4.1 million on the sale of loans for the six months ended June 30, 2021 compared to $2.3 million for the six months ended June 30, 2020. The income from sales of loans increased due to the increase in volume of mortgage loans originated because of record low mortgage rates.

Noninterest income included non-sufficient fund fees totaling $11.1 million and $13.3 million during the six months ended June 30, 2021 and 2020, respectively. This represents 13.2% and 19.7% of the Company’s noninterest income for the respective periods. In addition, the Company had debit card interchange fees totaling $22.5 million and $17.3 million during the six months ended June 30, 2021 and 2020, respectively. This represents 26.6% and 25.7% of the Company’s noninterest income for the respective periods. Government assistance funds that flowed into the market, including PPP loans and stimulus payments to households, increased both customer liquidity and interchange volume. This activity resulted in lower non-sufficient funds fees and higher debit card interchange fees for the six months ending June 30, 2021 compared to June 30, 2020.

Prior to the COVID-19 pandemic, there was little or no likelihood that the Company would surpass $10 billion in total assets for several years. However, with the CARES Act, including PPP loans, stimulus payments to households, and artificially high household savings rates, our deposits and assets have grown dramatically beyond reasonably foreseeable levels. To the extent the COVID-19 pandemic continues and the government response to it continues on the same or similar basis, it is likely the Company will exceed $10 billion in total assets at December 31, 2021. 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 $17 to $20 million beginning July 1, 2022. The Company is undergoing efforts to reduce total assets below $10 billion at December 31, 2021, but the success of these efforts is uncertain.

Noninterest Expense

Noninterest expense, as presented in the preceding table, increased by $9.4 million for second quarter of 2021 compared to the second quarter of 2020. The increase in noninterest expenses was due to $3.2 million related to other real estate property operating costs, $4.0 million in acquisition related expenses, and approximately $1.3 million in net occupancy and depreciation primarily from the Company’s new corporate headquarters.

35

For the six months ended June 30, 2021, noninterest expense increased by $13.0 m illion compared to the six months ended June 30, 2020. The increase in noninterest expenses was due to approximately $4.6 million related to other real estate property operating costs, $4.0 million in acquisition related expenses, and approximately $2.5 million in net occupancy and depreciation primarily from the Company’s new corporate headquarters. The second quarter of 2020 included a $2.2 million gain on the sale of other real estate owned that reduced noninterest expense.

Income Taxes

The Company’s effective tax rate was 23.4% for the second quarter of 2021, compared to 18.1% for the second quarter of 2020. The lower effective tax rate for the second quarter of 2020 was due to a greater effect of tax credits resulting from lower income.

The Company’s effective tax rate on income before taxes was 21.2% for the first six months of 2021, compared to 19.1% for the first six months of 2020. The lower effective tax rate for the first six months of 2020 was due to a greater effect of tax credits resulting from lower income.

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 125.2% to $3.6 billion, from December 31, 2020 to June 30, 2021. The increase was primarily related to the increase in deposits from PPP and other government stimulus payments.

Securities

At June 30, 2021, total debt securities increased $8.6 million, or 1.5% compared to December 31, 2020. The size of the Company’s securities portfolio is determined by the Company’s liquidity and asset/liability management. The net unrealized gain on debt securities available for sale, before taxes, was $7.1 million at June 30, 2021, compared to a net unrealized gain of $9.9 million at

37

December 31, 2020. These unrealized gains are included in the Company’s stockholders’ equity as accumulated other comprehensive income, net of income tax, in the amounts of a gain of $5.4 million at June 30, 2021 and a gain of $7.4 million at December 31, 2020.

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. Equity securities are reported in other assets on the balance sheet. The balance of equity securities was $10.4 million at June 30, 2021 and $10.1 million at December 31, 2020. The Company reviews its portfolio of equity securities for impairment at least quarterly.

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

Loans

At June 30, 2021, total loans decreased $241.0 million or 3.7% compared to December 31, 2020. The decrease in loans was due primarily to a net decrease of approximately $284 million in PPP loans and the sale of approximately $21 million of loans from the Company’s Hugo, Oklahoma branch along with pay downs on loans. The decrease in loans were partially offset by the Company’s purchase of approximately $195 million in loans, from The First National Bank and Trust Company of Vinita, Oklahoma. At June 30, 2021, the balance of total PPP loans was $368.6 million, net of unamortized processing fees of $16.6 million.

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

Allowance for Credit Losses

On January 1, 2020, the Company adopted ASC 326, which replaces the incurred loss methodology with an expected loss methodology that is referred to as CECL. The allowance for credit losses to total loans represented 1.35% and 1.42% at June 30, 2021 and December 31, 2020, respectively. The decrease in the allowance for credit loss during the second quarter of 2021 was primarily driven by a reversal of provision during the quarter based on sustained improvements in the economy, both nationally and in Oklahoma, 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 purchased with credit deterioration.

Nonaccrual and Restructured Assets

At June 30, 2021, nonperforming and restructured assets decreased $754,000 to $81.9 million compared to December 31, 2020. The Company’s level of nonperforming and restructured assets has continued to be relatively low, equating to 0.74% of total assets at June 30, 2021 and 0.90% of total assets at December 31, 2020.

Nonaccrual loans totaled $29.8 million at June 30, 2021, compared to $37.5 million at December 31, 2020. At June 30, 2021, the Company’s nonaccrual loans decreased $7.7 million from year-end 2020, due to resolutions of several loans, which was slightly offset by $7.3 million of nonaccrual loans acquired from The First National Bank and Trust Company of Vinita, Oklahoma. 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, interest income is recognized on certain of these loans on a cash basis if the full collection of the remaining principal balance is not in doubt. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $1.2 million for the six months ended June 30, 2021 and $983,000 for the six months ended June 30, 2020. Only a small amount of this interest is expected to be ultimately collected. Approximately $3.5 million of nonaccrual loans were guaranteed by government agencies at June 30, 2021.

Restructured loans totaled $7.5 million at June 30, 2021 compared to $7.8 million at December 31, 2020. 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 decline. The above normal risk associated with nonperforming loans has been considered in the determination of the allowance for credit losses. At June 30, 2021, the allowance for credit losses as a percentage of nonperforming and restructured loans was 201.48%, compared to 182.26%, at December 31, 2020. The level of nonperforming loans and credit losses could rise over time as a result of adverse economic conditions.

38

Other real estate owned (OREO) and repossessed assets totaled $40.2 million at June 30, 20 2 1, compared to $32.5 million at December 31, 20 20. 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. At June 30, 2021, the Company’s OREO increased $8.0 million from December 31, 2020, and included approximately $4.0 million due to the repossession of one commercial real estate property, $2.4 million from the decommissioning of the Company’s previous headquarters, and $2.5 million for other real estate acquired from The First National Bank and Trust Company of Vinita, Oklahoma. As of both June 30, 2021 and December 31, 2020, other real estate owned included a commercial real estate property recorded at approximately $28 million. 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 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 $169.2 million and $168.9 million at June 30, 2021 and December 31, 2020, respectively.

On May 20, 2021, the Company recorded a core deposit intangible of approximately $1.9 million because of the purchase of assets and assumption of liabilities from The First National Bank and Trust Company of Vinita, Oklahoma. See 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 $81.9 million at June 30, 2021 and $80.7 million at December 31, 2020. In addition, other assets includes approximately $11.1 million in equity interest of a previous borrower in the oil and gas industry, which was received through bankruptcy proceedings in the fourth quarter of 2020. This asset is carried at cost less 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.

Low Income Housing and New Market Tax Credit Investments

During 2021, 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, 2020, 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, 2020.

Deposits

At June 30, 2021, deposits totaled $9.7 billion, an increase of $1.7 billion or 20.6% from the December 31, 2020 total. The increase in deposits was primarily related to deposits of proceeds from the PPP and other government stimulus payments. 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 June 30, 2021 and 98.2% at December 31, 2020. Noninterest-bearing deposits to total deposits were 46.0% at June 30, 2021, compared to 47.0% at December 31, 2020.

39

S ubordinated 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 $3.1 million at June 30, 2021, compared to $1.1 million at December 31, 2020.

Long-Term Borrowings

The Company 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. The Company’s assets, including residential first mortgages of $849.8 million, are pledged as collateral for the borrowings under the line of credit. As of June 30, 2021 and December 31, 2020, the Company had no advances outstanding under the line of credit from FHLB.

Capital Resources

Stockholders’ equity totaled $1.1 billion at both June 30, 2021 and December 31, 2020. In addition to net income of $90.7 million, other changes in stockholders’ equity during the six months ended June 30, 2021 included $1.7 million related to common stock issuances and $1.0 million related to stock-based compensation, that were partially offset by $22.3 million in dividends, $5.5 million from settlement of options in cash, and a $2.0 million decrease in other comprehensive income. The Company’s leverage ratio and total risk-based capital ratios at June 30, 2021, 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.

Liquidity Risk and Off-Balance Sheet Arrangements

There have not been any material changes in the Company’s liquidity and off-balance sheet arrangements included in Management’s Discussion and Analysis which was included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2020.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

There have been no significant changes in the Company’s disclosures regarding market risk since December 31, 2020, the date of its most recent annual report to stockholders.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures. Pursuant to Rule 13a-15 of the Securities Exchange Act of 1934 (the “Exchange Act”), the Company’s Chief Executive Officer, Chief Financial Officer and its Disclosure Committee, which includes the Company’s Executive Chairman, Chief Risk Officer, Chief Internal Auditor, Chief Asset Quality Officer, Controller, General Counsel and Vice President of Corporate Finance, have evaluated, as of the last day of the period covered by this report, the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act).

Changes in Internal Control Over Financial Reporting. During the period to which this report relates, there have not been any changes in the Company’s internal controls over financial reporting (as defined in Rule 13a-15(f) and 15d-15(f) under the Exchange Act) that have materially affected, or are reasonably likely to materially affect, such controls.

PART II – OTHER INFORMATION

Item 1. Legal Proceedings.

The Company has been named as a defendant in various legal actions arising from the conduct of its normal business activities. Although the amount of any liability that could arise with respect to these actions cannot be accurately predicted, in the opinion of the Company, any such liability will not have a material adverse effect on the consolidated financial statements of the Company.

Item 1A. Risk Factors.

Except as set forth below, as of June 30, 2021, there have been no material changes from the risk factors previously disclosed in Part I, Item 1A, of the Company’s Annual Report on Form 10-K for the year ended December 31, 2020:

The Durbin Amendment is a provision in the larger Dodd-Frank Act that gave the Federal Reserve the authority to establish rates on debit card transactions. The Durbin Amendment aims to control debit card interchange fees and restrict anti-competitive practices. The law applies to banks with over $10 billion in assets and limits what these banks may charge for debit card interchange fees. At December 31, 2020, the Company’s assets did not exceed $10 billion, but at June 30, 2021 the Company’s assets did exceed $10 billion. Prior to the COVID-19 pandemic, there was little or no likelihood that the Company would surpass $10 billion in total assets for several years. However, with the CARES Act, including PPP loans, stimulus payments to households, and artificially high household savings rates, our deposits and assets have grown dramatically beyond reasonably foreseeable levels. To the extent the COVID-19 pandemic continues and the government response to it continues on the same or similar basis, it is likely the Company will exceed $10 billion in total assets at December 31, 2021. 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 $17 to $20 million beginning July 1, 2022. The Company is undergoing efforts to reduce total assets below $10 billion at December 31, 2021, but the success of these efforts is uncertain.

Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.

None.

Item 3. Defaults Upon Senior Securities.

None.

Item 4. Mine Safety Disclosures.
