All such adjustments are of a normal and recurring nature.

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.

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.

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) No. 2018-13, “Disclosure Framework – Changes to the Disclosure Requirements for Fair Value Measurement (Topic 820).” ASU 2018-13 modifies disclosure requirements on fair value measurements in Topic 820. ASU 2018-13 was effective for the Company on January 1, 2020. ASU No. 2018-13 was adopted on January 1, 2020 and did not have a significant impact on the Company’s financial statements.

On January 1, 2020, the Company adopted ASU No. 2016-13, “Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments.” Accounting Standards Codification (“ASC”) 326 replaces the incurred loss methodology with an expected loss methodology that is referred to as the current expected credit loss (“CECL”) methodology. The measurement of expected credit losses under the CECL methodology is applicable to financial assets measured at amortized cost, including loan receivables and held-to-maturity debt securities. It also applies to off-balance sheet credit exposures not accounted for as insurance (loan commitments, standby letters of credit, financial guarantees, and other similar instruments) and net investments in

leases recognized by a lessor in accordance with Topic 842 on leases. In addition, ASC 326 made changes to the accounting for purchased loans and securities with credit deterioration and available-for-sale debt securities.

The Company adopted ASC 326 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures. Operating results for periods from January 1, 2020 are presented in accordance with ASC 326 while prior period amounts continue to be reported in accordance with previously applicable standards and the accounting policies described in our 2019 Form 10-K. The Company recorded a net increase to retained earnings of $2.3 million, net of tax of $925,000, as of January 1, 2020 for the cumulative effect of adopting ASC 326, and the impact on our results of operations and cash flows was not material.

The Company adopted ASC 326 using the prospective transition approach for financial assets purchased with credit deterioration (PCD) that were previously classified as purchased credit impaired (PCI) and accounted for under ASC 310-30. In accordance with the standard, management did not reassess whether PCI assets met the criteria of PCD assets as of the date of adoption. On January 1, 2020, the amortized cost basis of the PCD assets was adjusted to reflect the addition of approximately $1.2 million to the allowance for credit losses.

The Company has not recorded an allowance for credit losses against its available-for-sale securities, as the credit risk is not material. The following table illustrates the impact of ASC 326 on the allowance for credit losses on the Company’s loans as of January 1, 2020.

The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. In order to estimate expected losses using historical loss information, the Company elected to utilize a methodology known as vintage loss analysis for substantially all of our loan portfolio. Vintage loss analysis measures impairment based on the age of the accounts and the historical asset performance of assets with similar risk characteristics. Vintage loss analysis accounts for expected losses by allowing the Company to calculate the cumulative loss rates of a given loan pool and in so doing, determine the loan pool’s lifetime expected loss experience. This includes a reasonable approximation of probable and estimable future losses determined by applying historical net charge off information to forward looking qualitative and environmental factors. First, the Company determined the appropriate type of financial assets that share similar risk characteristics, and then the Company developed a cumulative loss curve for the applicable financial assets based on historical data using different “vintages” analyzed by year of origination. This is done by dividing each year’s net charge-offs by the original principal balance. The respective vintage’s original principal balance remains the denominator in each annual calculation, as it references the specific vintage’s original balance. The loss experience of this original balance is tracked annually and summed over the life of the loan for each separate loan pool leaving a cumulative, life of credit loss rate based on historic averages weighted towards more recent loss experience. In addition to life of credit loss data, primary drivers like macroeconomic indicators of qualitative factors are used as adjustments to the expected loss calculation to reach a forecast supported by both quantitative and qualitative data points. The intent is to express the impact of changes in external factors while incorporating analysis of where the loan pool is in its loss history.

Loans that do not share risk characteristics are evaluated on an individual basis. Loans evaluated individually are not included in the collective evaluation. The Company has made the accounting policy election to use the fair value of the collateral to measure expected credit losses on collateral-dependent financial assets. 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 connection with the adoption of ASC 326, the Company revised certain accounting policies and implemented accounting policy elections. The revised accounting policies are described below.~~

~~Loans~~: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts. Accrued interest receivable totaled $31.0 million at June 30, 2020 and $27.4 million at December 31, 2019, and was reported in accrued interest receivable and other assets on the consolidated balance sheets. ~~The Company has made the accounting policy election to exclude accrued interest receivable on loans from the estimate of credit losses.~~ ~~Interest income is accrued on the unpaid principal balance using the simple-interest method on the daily balances of the principal amounts outstanding.~~

Interest income on consumer and commercial loans is discontinued and placed on nonaccrual status at the time the loan is 90 days delinquent unless the loan is well secured and in process of collection. Consumer loans are charged off at 180 days past due and commercial loans are charged off to the extent principal or interest is deemed uncollectible. Past-due status is based on the contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged off at an earlier date if collection of principal or interest is considered doubtful.

All interest accrued but not received for loans placed on nonaccrual is reversed against interest income. Interest received on such loans is accounted for on the cash-basis or cost-recovery method, until qualifying for return to accrual. Under the cost-recovery method, interest income is not recognized until the loan balance is reduced to zero. Under the cash-basis method, interest income is recorded when the payment is received in cash. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Troubled debt restructurings are loans on which, due to the borrower’s financial difficulties, the Company has granted a concession that the Company would not otherwise consider for borrowers of similar credit quality. This may include a transfer of real estate or other assets from the borrower, a modification of loan terms, or a combination of the two. Modifications of terms that could potentially qualify as a restructuring include reduction of contractual interest rate, extension of the maturity date at a contractual interest rate lower than the current rate for new debt with similar risk, and a reduction of the face amount of debt or forgiveness of either principal or accrued interest. A loan continues to qualify as restructured until a consistent payment history or change in the borrower’s financial condition has been evidenced, generally for no less than twelve months. If the restructuring agreement specifies an interest rate at the time of the restructuring that is greater than or equal to the rate that the Company is willing to accept for a new extension of credit with comparable risk, then the loan is no longer considered a restructured loan if it is in compliance with the modified terms in calendar years after the year of restructure.

~~Purchased Credit Deteriorated (PCD) Loans~~: The Company has purchased loans, some of which have experienced more than insignificant credit deterioration since origination. An allowance for credit losses is determined using the same methodology as other loans held for investment. The initial allowance for credit losses determined on a collective basis is allocated to individual loans. The sum of the loan’s purchase price and allowance for credit losses becomes its initial amortized cost basis. The difference between the initial amortized cost basis and the par value of the loan is a noncredit discount or premium, which is amortized into interest income over the life of the loan. Subsequent changes to the allowance for credit losses are recorded through provision expense.

~~Allowance for Credit Losses - Loans~~: The allowance for credit losses is a valuation account that is deducted from the loans amortized cost basis to present the net amount expected to be collected on the loans. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off.

The allowance for credit losses is measured on a collective (pool) basis when similar risk characteristics exist. In connection with our adoption of ASC 326, changes were made to our primary portfolio segments to align with the methodology applied in determining the allowance under CECL. The Company has identified the following portfolio segments, which includes the applicable weighted average life, and measures the allowance for credit losses using the vintage loss analysis adjusted for qualitative factors:

These portfolio segments are separately identified because they exhibit distinctive risk characteristics, such as financial asset types, loan purpose, collateral, and industry of the borrower. A summary of our primary portfolio segments is as follows:

~~Commercial real estate owner occupied.~~ Commercial real estate owner occupied are nonresidential property loans for which the primary source of repayment is the cash flow from the ongoing operations and activities conducted by the entity, or an affiliate of the entity, who owns the property. This category includes, among other loans, loans secured by office buildings, garden office buildings, manufacturing facilities, warehouse and flex warehouse facilities, hospitals, and car washes unless the property is owned by an investor who leases the property to the operator who, in turn, is not related to or affiliated with the investor.

~~Commercial real estate non-owner occupied.~~ Commercial real estate non-owner occupied are nonresidential property loans where the primary source of repayment is derived from rental income associated with the property or the proceeds of the sale, refinancing, or permanent financing of the property. This category includes, among other loans, loans secured by shopping centers, office buildings, hotels/motels, nursing homes, assisted-living facilities, mini-storage warehouse facilities, and similar properties.

~~Construction and development < 60 months~~. Residential development loans include loans to develop raw land into a residential development. Advances on the loans typically include land costs, hard costs (grading, utilities, roads, etc.), soft costs (engineering fees, development fees, entitlement fees, etc.) and carrying costs until the development is completed. Upon completion of the development, the loan is typically repaid through the sale of lots to homebuilders.

~~Construction residential real estate < 60 months.~~Residential construction includes loans to builders for speculative or custom homes, as well as direct loans to individuals for construction of their personal residence. Custom construction and self-construction loans typically will have commitments in place for long-term financing at the completion of construction. Speculative construction loans generally will have periodic curtailment plans beginning after completion of construction and a reasonable time for sales to have occurred.

~~Residential real estate first lien.~~ Residential real estate first lien loans includes all closed-end loans secured by first liens on 1-to-4 family residential properties. This category includes property containing 1-to-4 dwelling units (including vacation homes) or more than four dwelling units if each is separated from other units by dividing walls that extend from ground to roof. This category also includes individual condominium dwelling units and loans secured by an interest in individual cooperative housing units, even if in a building with five or more dwelling units.

~~Residential real estate all other.~~ Residential real estate all other loans includes loans secured by junior (i.e., other than first) liens on 1-to-4 family residential properties. This category includes loans secured by junior liens even if the Company also holds a loan secured by a first lien on the same 1-to-4 family residential property.

~~Farmland.~~ This category includes loans secured by all land known to be used or usable for agricultural purposes, such as crop and livestock production. Farmland includes grazing or pasture land, whether tillable or not and whether wooded or not.

~~Commercial and agricultural non-real estate.~~ Commercial and agricultural non-real estate represent loans for working capital, facilities acquisition or expansion, purchase of equipment and other needs of commercial customers primarily located within Oklahoma. Loans in this category include commercial and industrial, oil and gas, agriculture and state and political subdivisions.

~~Consumer non-real estate.~~ Consumer loans are loans to individuals for household, family and other personal expenditures. Commonly, such loans are made to finance purchases of consumer goods, such as automobiles, boats, household goods, vacations and education.

~~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.

~~Pegasus Bank.~~ Pegasus Bank’s loans are commercial and consumer loans mostly to customers within Texas secured by real estate. Pegasus Bank also includes commercial and industrial loans, which includes loans to companies in the oil and gas industry.

The Company considers various factors to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical loan loss experience and economic conditions.

Management estimates the allowance balance using relevant available information, from internal and external sources, relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit loss experience provides the basis for the estimation of expected credit losses. Adjustments to historical loss information are made for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency level, or term as well as for changes in environmental conditions, such as the political, legal, and regulatory environment, technology and consumer preferences. Historical loss information is also adjusted for reasonable and supportable changes in national and local economic conditions, such as oil and gas prices, national and local unemployment, real gross domestic product (“GDP”), house price index (“HPI”), consumer price index (“CPI”), rental vacancies, and retail sales. Economic conditions are forecast as "current conditions" over the forecast period. Forecast models were used to validate credit performance during the forecast period. Beyond the reasonable and supportable forecast, the economic expectation reverts to the historical average, which is determined by the weighted average life of each loan pool.

~~Determining the Contractual Term:~~ Expected credit losses are estimated over the contractual term of the loans, adjusted for expected prepayments when appropriate. The contractual term excludes expected extensions, renewals, and modifications unless either of the following applies: management has a reasonable expectation at the reporting date that a troubled debt restructuring will be executed with an individual borrower or the extension or renewal options are included in the original or modified contract at the reporting date and are not unconditionally cancellable by the Company.

~~Troubled Debt Restructurings (TDRs~~): The allowance for credit loss on a TDR is measured using the same method as all other loans held for investment, except when the value of a concession cannot be measured using a method other than the discounted cash flow method. When the value of a concession is measured using the discounted cash flow method, the allowance for credit loss is determined by discounting the expected future cash flows at the original interest rate of the loan.

~~Allowance for Credit Losses on Off-Balance Sheet Credit Exposures~~: The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on off-balance sheet credit exposures is adjusted as a provision for credit loss expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life. Based on a low likelihood that funding will occur and the Company’s ability to manage the extension of credit to our borrowers, the allowance for credit losses on off-balance sheet credit exposure is not material.

~~Allowance for Credit Losses - Available-for-Sale Securities~~: The Company reviews its portfolio of securities in an unrealized loss position at least quarterly. The Company first assesses whether it intends to sell or it is more-likely-than-not that it will be required to sell the securities before recovery of the amortized cost basis. If either of these criteria is met, the securities amortized cost basis is written down to fair value as a current period expense. If either of the above criteria is not met, the Company evaluates whether the decline in fair value is the result of credit losses or other factors. In making this assessment, the Company considers, among other things, the period of time the security has been in an unrealized loss position, and performance of any underlying collateral and adverse conditions specifically related to the security. At December 31, 2019 and June 30, 2020 approximately 95% of the available for sale securities held by the Company were issued by the U.S. Treasury, or U.S. government-sponsored entities and agencies. The Company does not consider the unrealized position of these securities to be the result of credit factors, because the decline in fair value is attributable to changes in interest rates and illiquidity, and not credit quality, and the Company does not have the intent to sell these securities and it is likely that it will not be required to sell the securities before their anticipated recovery. Therefore, the Company has not recorded an allowance for credit losses against its securities portfolio, as the credit risk is not material.

~~PPP Fee Income Policy:~~ The PPP, established as part of the Coronavirus Aid, Relief, and Economic Security (CARES) Act, provides that the SBA will pay processing fees of up to 5% to lenders based on the volume of the PPP loans disbursed. The fee is based on the balance of each PPP loan outstanding at the time of full disbursement. As of June 30, 2020, the Company received approximately $30.0 million in processing fees from the SBA. The unamortized balance of these fees is reported on the Company's balance sheet as part of the loan balance to which it relates and is recognized over the remaining life of the loan as an adjustment of yield. Upon notification from the SBA of the amount of the PPP loan to be forgiven the acceleration of recognition of deferred loan fee will occur for the percentage of the loan forgiven.

Section 4013 of the CARES Act and the Interagency Statement on Loan Modifications by Financial Institutions provides temporary relief from the accounting and reporting requirements for TDRs regarding certain loan modifications related to COVID-19 that are offered by financial institutions

Specifically, the CARES Act provides that a financial institution may elect to suspend (1) the requirements under U.S. GAAP for certain loan modifications that would otherwise be categorized as a TDR and (2) any determination that such loan modifications would be considered a TDR, including the related impairment for accounting purposes. The modifications that would qualify for this exception include any modification involving a loan that was not more than 30 days past due as of December 31, 2019, that occurs during the “applicable period,” including any of the following:

The exception does not apply to any adverse impact on the credit of a borrower that is not related to the COVID-19 pandemic. Furthermore, even when the exception is applied, an entity may determine that it is appropriate to place the loan on nonaccrual status. As of June 30, 2020,On February 19, 2021, the Company ~~has identified $939.8 million in loans that have been modified according~~entered into a purchase and assumption agreement with The First National Bank and Trust Company of Vinita, Oklahoma to ~~these terms.~~

~~On March 5, 2020, the Company purchased approximately $47.8 million in total~~purchase certain of its assets ~~which included $22.9 million in loans,~~ and ~~assumed approximately $45.0 million in~~assume its deposits and certain other ~~obligations~~obligations. The First National Bank and Trust Company of ~~The Citizens State Bank of Okemah, Oklahoma “Citizens” for~~Vinita is a purchase price of $2.9 million. As a result of the purchase, the Company recorded a core deposit intangible of approximately $206,000 and goodwill of approximately $1.3 million. The effect of this purchase was included in the consolidated financial statements of the Company from the date of purchase forward. The purchase did not have a material effect on the Company’s consolidated financial statements. Citizens was an Oklahoma state-charterednationally chartered bank with banking locations in ~~Okemah~~Vinita and ~~Paden,~~Grove, Oklahoma. These banking locations ~~became~~would become branches of BancFirst.

~~In January~~ As of December 31, 2020, the First National Bank and Trust Company ~~sold property held~~of Vinita had approximately $285 million in ~~other real estate owned for a $2.2~~total assets, $209 million ~~gain.~~in loans, and $258 million in deposits. The purchase and assumption is expected to be completed during the second quarter of 2021 and is subject to regulatory approval.

On ~~August 15, 2019~~January 22, 2021, the Company ~~acquired Pegasus~~sold approximately $21 million in loans and approximately $38 million in deposits from its Hugo, Oklahoma branch to AmeriState Bank ~~a Texas state-charted bank with three banking locations~~ in ~~Dallas, Texas. This acquisition~~Atoka, Oklahoma. A gain on the transaction of $2.5 million is ~~disclosed~~reflected in ~~Note (2) to~~ the ~~Company’s Annual Report on Form 10-K for the year ended December 31, 2019.~~first quarter of 2021.

Due to the impacts of the COVID-19 pandemic, the Company ~~has modified~~had approximately ~~$939.8~~$88 million in modified loans as of March 31, 2021 and $81.7 million in modified loans as of December 31, 2020, most of which ~~are~~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. ~~Consequently, it is reasonable to expect that when temporary regulatory accounting relief and payment modifications cease, there will be a marked increase in credit impairment and restructured loans.~~ The timing and extent of such consequences are ~~impossible~~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~~Current Loans in the table above.

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, ~~2019.~~2020.

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

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. ~~See Note (1) for additional information regarding the factors that influenced the Company’s current estimate of expected credit losses.~~ Upon adoption, the allowance for credit losses was decreased by $3.2 million, with no impact to the consolidated statement of income. ~~Subsequent to the adoption of ASC 326, the Company recorded a $38.9 million provision~~

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 life of the Company’s loans segments are disclosed in Note (1) to the Company’s Annual Report on Form 10-K for the first six months of 2020 utilizing the newly adopted CECL methodology, a significant increase from the first six months of 2019. The increase resulted primarily from the anticipated impact on our loan portfolio resulting from the economic outlook related to the COVID-19 pandemic and the decline in energy prices and to a lesser degree, loan growth during the first six months ofyear ended December 31, 2020. Prolonged low energy prices will not only have a direct impact on the energy portfolio; it will have an indirect effect on the economies of Oklahoma and the Dallas, Texas market, including higher unemployment, with a residual effect on land values and real estate prices.

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																				Allowance for Credit Losses
	Balance at beginning of period		Impact of CECL adoption			Initial allowance on loans purchased with credit deterioration		Charge- offs			Recoveries		Net charge-offs			Provision for credit losses on loans			Balance at end of period		Balance at beginning of period		Charge- offs			Recoveries		Net charge-offs			Provision for credit losses on loans			Balance at end of period

A loan is considered collateral-dependent when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. During the three months ended March 31, 2021 and 2020, no material amount of interest income was recognized on collateral-dependent loans subsequent to their classification as collateral-dependent. The following table summarizes collateral-dependent gross loans held for investment by collateral type and the related specific allocation as follows:

The Company has had a nonqualified incentive stock option plan the BancFirst Corporation Stock Option Plan (the ~~“BancFirst ISOP”~~“Employee Plan”) since May 1986. At ~~June 30, 2020,~~March 31, 2021, there were ~~330,000~~167,500 shares available for future grants. The ~~BancFirst ISOP~~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 ~~“BancFirst~~“Non-Employee Directors’ ~~Stock Option~~ Plan”) since June 1999. Each non-employee director is granted an option for 10,000 shares. At ~~June 30, 2020,~~March 31, 2021, there were 30,000 shares available for future grants. The ~~BancFirst~~Non-Employee Directors’ ~~Stock Option~~ 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 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 cost of $3.6 million that did not increase the outstanding shares of the Company.

The following table is a summary of the activity under both the ~~BancFirst ISOP~~Employee Plan and the ~~BancFirst~~Non-Employee Directors’ ~~Stock Option~~ Plan:

The following table has additional information regarding options exercised under both the ~~BancFirst ISOP~~Employee Plan and the ~~BancFirst~~Non-Employee Directors’ ~~Stock Option~~ Plan:

	Three Months Ended June 30,				Six Months Ended June 30,				Three Months Ended March 31,

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,				Three Months Ended March 31,

Stock-based compensation expense, net of tax	$	303	$	273	$	620	$	403	$	429	$	317

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:

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,				Three Months Ended March 31,
	2020		2019		2021		2020
Weighted average grant-date fair value per share of options granted	$	10.63	$	13.67	$	23.80	$	10.56
Risk-free interest rate	0.66 to 1.13%		2.62 to 2.76%		1.34 to 1.64%		1.13%
Dividend yield	2.00%		2.00%		2.00%		2.00%
Stock price volatility	22.84 to 33.56%		22.93 to 22.96%		35.55 to 35.73%		22.84%
Expected term	10 Yrs		10 Yrs		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 ~~“BancFirst Deferred~~“Deferred Stock Compensation Plan”) since May 1999. As of ~~June 30, 2020,~~March 31, 2021, there are ~~28,582~~19,717 shares available for future issuance under the ~~BancFirst~~ Deferred Stock Compensation Plan. The ~~BancFirst~~ 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 ~~1,307~~2,161 and ~~8,362~~1,307 shares of common stock distributed from the ~~BancFirst~~ Deferred Stock Compensation Plan during the ~~six~~three months ended ~~June 30,~~March 31, 2021 and March 31, 2020, ~~and June 30, 2019,~~ respectively.

Average price	$	27.85	$	27.17	$	29.14	$	28.57

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,~~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 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, 2020,~~March 31, 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, 2020,~~March 31, 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 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 0 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 ~~the second quarter of~~ 2020 and 2021 are included in the calculation of the Company’s leverage ratio as of ~~June 30, 2020~~March 31, 2021 as the Company did not utilize the PPP Facility for funding purposes.

As discussed in Note 1 - Significant Accounting Policies, in connection with the adoption of ASC 326, the Company recognized an after-tax cumulative effect reduction to retained earnings totaling $2.3 million. In February 2019, the federal bank regulatory agencies issued a final rule (the “2019 CECL Rule”) that revised certain capital regulations to account for changes to credit loss accounting under U.S. GAAP. The 2019 CECL Rule included a transition option that allows banking organizations to phase in, over a three-year period, the day-one adverse effects of CECL on their regulatory capital ratios (three-year transition option). In March 2020, the federal bank regulatory agencies issued an interim final rule that maintains the three-year transition option of the 2019 CECL Rule and also provides banking organizations that were required under U.S. GAAP (as of January 2020) to implement CECL before the end of 2020 the option to delay for two years an estimate of the effect of CECL on regulatory capital, relative to the incurred loss methodology’s effect on regulatory capital, followed by a three-year transition period (five-year transition option). The Company elected not to adopt the five-year ~~transition option.~~

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:

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.

~~Securities~~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 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 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 securities.

The Company reviews the prices for Level 1 and Level 2 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 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 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:

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~~three months ended ~~June 30,~~March 31, 2021, the Company transferred securities from Level 3 to Level 2 due to a review of the

pricing models that determined some asset backed securities to be Level 2. During the year ended December 31, 2020, the Company transferred 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. ~~During the twelve months ended December 31, 2019, the Company did 0t transfer any securities between levels in the fair value hierarchy.~~

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. ~~Beginning January 1, 2018, upon adoption of ASU 2016-01, these~~These 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 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.~~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:

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.

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

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 securities making adjustments for credit or liquidity if applicable.

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.

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 including PPP~~ 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.

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.

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

~~The fair values of fixed-rate long-term borrowings are estimated using rates that would be charged for borrowings of similar remaining maturities.~~

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

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,				March 31,				December 31,

The financial information for each business unit is presented on the basis used internally by management to evaluate performance and allocate resources. The Company utilizes a transfer pricing system to allocate the benefit or cost of funds provided or used by the various business units. Certain services provided by the support group to other business units, such as item processing, are allocated at rates approximating the cost of providing the services. Eliminations are adjustments to consolidate the business units and companies. ~~Capital expenditures are generally charged to the business unit using the asset.~~

For the three months ended ~~June 30, 2020,~~March 31, 2021, net interest income, which is the Company’s principal source of operating revenue, increased ~~$8.4~~$3.1 million or ~~12.2%~~4.2% compared to the three months ended ~~June 30, 2019.~~March 31, 2020. Net interest income increased for the first quarter of 2021 due to loan growth, PPP fee income of approximately $9.8 million and the ~~drop~~decrease in interest rates paid on deposits. 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~~first quarter of

~~2020~~ 2021 decreased compared to the ~~second~~first quarter of ~~2019,~~2020, primarily due to the lower average rates on ~~federal funds and securities during the quarter.~~

~~Net interest income for the six months ended June 30, 2020 increased $15.6 million or 11.5% compared to the six months ended June 30, 2019. Net interest income increased due to loan growth,~~ ~~PPP~~ fee income 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, 2020 decreased compared to the six months ended June 30, 2019, primarily due to the lower average rates onloans, federal funds and securities during the quarter.

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 on-going response in Federal Reserve policy driven by the economic disruption arising from the COVID-19 pandemic.

~~The Company’s~~For the first quarter of 2021, no provision for credit losses was recorded, compared to a provision for credit losses of $19.6 million for the ~~second~~first quarter of 2020. The Company’s lack of provision for the first quarter of 2021 was based on improvements in economic conditions and the Company’s outlook for certain economic indicators. The elevated provision during the first quarter of 2020 was $19.3 million compared to $2.4 million a year ago. The increase in the provision was related to reserve build up for expected credit losses stemming from the COVID-19 pandemic and low energy prices. The Company’s provision this quarter is based on ~~a modestly optimistic assumption 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. To the extent the amount of time the economy remains adversely affected is more extended than the Company’s current base projection, the Company will see a continuation of higher than normal provision in future periods. 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 ~~recoveries~~charge-offs were ~~$87,000~~$506,000 for the ~~second~~first quarter of ~~2020,~~2021, compared to net loan charge-offs of ~~$240,000~~$1.0 million for the ~~second~~first quarter of ~~2019.~~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, 2020, the Company’s provision for credit losses was $38.9 million compared to $4.1 million for the six months ended June 30, 2019. Net loan charge-offs were $961,000, compared to $398,000 for the same period of the prior year.

Noninterest income, as presented in the preceding table, ~~decreased~~increased by ~~$2.0~~$4.8 million for ~~second~~first quarter of 2021 compared to the first quarter of 2020. The increase in noninterest income was due to a gain from the sale of the Company’s Hugo, Oklahoma branch of $2.5 million, $2.4 million in rental income from a real estate property foreclosed on in the fourth quarter of 2020, ~~compared to the second quarter~~and a $1.2 million increase in income from sales of ~~2019. The~~mortgage loans, which were partially offset by a $1.3 million decrease in ~~noninterest income is primarily due to a decrease in deposit service charges resulting from lower economic activity and equity security losses.~~ treasury management income.

Noninterest income included non-sufficient funds fees totaling ~~$5.0~~$5.5 million and ~~$8.1~~$8.3 million for the three month periods ended ~~June 30,~~March 31, 2021 and 2020, ~~and 2019,~~ respectively. This represents ~~15.6%~~13.8% and ~~23.8%~~23.5% of the Company’s noninterest income for the three month periods ended ~~June 30,~~March 31, 2021 and 2020, ~~and 2019,~~ respectively. In addition, the Company had ~~fees from~~ debit card ~~usage~~interchange fees totaling ~~$9.1~~$10.7 million and ~~$8.7~~$8.2 million during the three month periods ended ~~June 30,~~March 31, 2021 and 2020, ~~and 2019,~~ respectively. This represents ~~28.5%~~26.7% and ~~25.6%~~23.3% of the Company’s noninterest income for the three month periods ended ~~June 30,~~March 31, 2021 and 2020, ~~and 2019,~~ respectively.

~~Noninterest income for~~ For the ~~six months ended June 30, 2020 totaled $67.2 million~~first quarter of 2021 compared to ~~$66.1 million for~~ the ~~six months ended June 30, 2019. The increase~~first quarter of 2020, government assistance funds that flowed into the market, including PPP loans and stimulus payments to households, increased customer liquidity and higher volume of transactions. This activity resulted in ~~noninterest income was primarily due to growth in debit card usage~~lower non-sufficient funds fees and sweep fees, partially offset by decreased service charges on deposits and equity security losses. Noninterest income included fees from debit card usage totaling $17.3 million and $16.5 million during the six months ended June 30, 2020 and 2019, respectively. This represents 25.7% and 25.0% of the Company’s noninterest income for the six month periods ended June 30, 2020 and 2019, respectively. In addition, the Company had non-sufficient fund fees totaling $13.3 million and $15.7 million during the six months ended June 30, 2020 and 2019, respectively. This represents 19.7% and 23.8% of the Company’s noninterest income for the six month periods ended June 30, 2020 and 2019, respectively.

~~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~~higher debit card interchange ~~fees and restrict anti-competitive practices. The law applies to banks with over $10 billion in assets and limits these banks on what they charge for debit card interchange~~ fees.

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 ~~has a heightened possibility of exceeding~~will exceed $10 billion in total assets at December 31, ~~2020.~~2021. Pursuant to the Durbin ~~amendment~~Amendment of the Dodd-Frank Act, based on current run rates, this would trigger an approximate ~~loss~~reduction of annual pretax income from debit card interchange fees of between ~~$16 and $18~~$17 to $20 million ~~in subsequent years.~~ beginning July 1, 2022.

The Company ~~is developing strategies~~earned $2.0 million on the sale of loans for first quarter of 2021 compared to ~~avoid exceeding $10 billion~~$781,000 for first quarter of 2020. The income from sales of loans increased due to the increase in ~~assets and the loss~~volume of ~~interchange income, but the success of these strategies is uncertain.~~loans originated due to record low mortgage rates.

Noninterest expense, as presented in the preceding table, increased by ~~$8.0~~$3.6 million for ~~second~~first quarter of ~~2020~~2021 compared to the ~~second~~first quarter of ~~2019.~~2020. The increase in noninterest expenses was ~~primarily~~ due to ~~salary increases in 2020 related to annual merit increases, noninterest expenses~~$1.4 million of ~~Pegasus Bank and COVID-19 pandemic related salary expenses.~~

For the six months ended June 30, 2020, noninterest expense increased by $13.2 million compared to the six months ended June 30, 2019. The increase in noninterest expenses was primarily due to salary increases in 2020 related to annual merit increases, pandemic related salary expenses, noninterest expenses of Pegasus Bank and acquisition expenses related to a real estate property foreclosed on in the ~~purchase~~fourth quarter of ~~assets from Citizens, which were partially offset by~~2020 and a ~~$2.1~~$2.2 million gain on athe sale of ~~property carried in~~ other real estate ~~owned.~~ owned in the first quarter of 2020 that reduced noninterest expense.

The Company’s effective tax rate on income before taxes was 18.1% for the second quarter of 2020, compared to 22.0% for the second quarter of 2019. The decrease in the effective tax rate for the second quarter of 2020 was due to a greater effect of tax credits resulting from lower income.

The ~~decrease in the~~ effective tax rate was lower for the first ~~six months~~quarter of 2021 compared to the first quarter of 2020 ~~was due to a greater effect~~primarily because of an increase in employee options exercised during the quarter.

As shown on the Company’s cash flow statement, the primary use of cash~~March 31, 2021. The increase was ~~due~~primarily related to the increase in ~~loans.~~deposits from PPP and other government stimulus payments.

At ~~June 30, 2020,~~March 31, 2021, total debt securities ~~increased $116.4~~decreased $34.7 million, or ~~23.7%~~6.2% compared to December 31, ~~2019.~~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 ~~$13.0~~$8.6 million at ~~June 30, 2020,~~March 31, 2021, compared to a net unrealized gain of ~~$4.6~~$9.9 million

at December 31, ~~2019.~~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 ~~$9.7~~$6.4 million at ~~June 30, 2020~~March 31, 2021 and a gain of ~~$3.5~~$7.4 million at December 31, ~~2019.

See Note (3) of the ~~economic effects of~~Notes to Consolidated Financial Statements for disclosures regarding the COVID-19 pandemic. As the effects on the economy due to the COVID-19 pandemic became more apparent late in the first quarter, monetary flows were directed to high quality fixed income instruments such as short-term Treasury securities. Over the six-month period, the yield on the three-year Treasury note decreased 144 basis points with a corresponding increase in valuations.Company’s Securities.

At ~~June 30, 2020,~~March 31, 2021, total loans ~~totaled $6.7 billion, an increase of $1.0 billion from~~decreased $68.1 million or 1.1% compared to December 31, ~~2019.~~2020. The ~~increase~~decrease in loans was ~~primarily related~~partially due to ~~the PPP, internal growth and the purchase~~approximately $21 million of loans ~~from Citizens.~~that were sold with the Company’s Hugo, Oklahoma branch. At ~~June 30, 2020,~~March 31, 2021, the balance of ~~the~~total PPP loans was ~~$825.1~~$713.7 million, net of unamortized processing fees of ~~$26.2~~$23.3 million. Prolonged low energy prices will not only have a direct impact on the energy portfolio; it will have an indirect effect on the economies of Oklahoma and the Dallas, Texas market, including higher unemployment, with a residual effect on land values and real estate prices. At June 30, 2020, the Company had the following exposures to industries adversely impacted by the COVID-19 pandemic: energy $448.2 million, medical $167.1 million, hotels/motels $130.2 million and restaurants $88.9 million. In total, these industries represented approximately 13%

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

In addition, due to the impacts of the COVID-19 pandemic, the Company has modified approximately $939.8 million in loans, most of which are 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. Consequently, it is reasonable to expect that when temporary regulatory accounting relief and payment modifications cease, there will be a marked increase in credit deteriorated and restructured loans. The timing and extent of such consequences are impossible 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.portfolio segments.

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. ~~As a result, the Company recorded a decrease to the allowance for credit losses of $3.2 million at January 1, 2020.~~ At ~~June 30,~~March 31, 2021 and December 31, 2020, the allowance for credit losses to total loans represented ~~1.34%~~1.42% of total ~~loans,~~loans.

At March 31, 2021, nonperforming and restructured assets decreased $3.9 million to $78.7 million compared to ~~0.96%~~December 31, 2020. The Company’s level of nonperforming and restructured assets has continued to be relatively low, equating to 0.75% of total assets at March 31, 2021 and 0.90% of total assets at December 31, ~~2019. The increase in the allowance for credit losses related~~2020.

Nonaccrual loans totaled $35.3 million at March 31, 2021, compared to ~~reserve build up for expected credit losses stemming from the COVID-19 pandemic and low energy prices.~~

The fair value adjustment on acquired loans consists of an interest rate component to adjust the effective rates on the loans to market rates and a credit component to adjust for estimated credit exposures in the acquired loans. The interest rate component was $875,000 at June 30, 2020 and $1.7$37.5 million at December 31, 2019. The credit component of the adjustment was $4.4 million at June 30, 2020 and $6.8 million at December 31, 2019. These fair value adjustments will be accreted to income over the remaining life of the loans.

~~Nonaccrual loans totaled $49.5 million at June 30, 2020, compared to $18.0 million at the end of 2019. The increase in nonaccrual loans was due to further downgrades of energy loans.~~2020. The Company’s nonaccrual loans are primarily commercial and ~~real~~agricultural non-real estate ~~loans.~~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 orand principal ~~or both~~ 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 ~~reasonably expected. Otherwise, interest income is~~ not ~~recognized until the principal balance is fully collected.~~in doubt. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately ~~$983,000~~$521,000 for the ~~six~~

three months ended ~~June 30, 2020~~March 31, 2021 and ~~$1.0 million~~$332,000 for the ~~six~~three months ended ~~June 30, 2019.~~March 31, 2020. Only a small amount of this interest is expected to be ultimately collected. Approximately $6.6 million of nonaccrual loans were guaranteed by government agencies at March 31, 2021.

~~Troubled debt restructured~~Restructured loans totaled ~~$3.2~~$7.8 million at ~~June 30, 2020, compared to $18.0 million at the end of 2019. The decrease in troubled debt restructurings was due primarily to a review of troubled debt restructurings during the period~~both March 31, 2021 and ~~the related performance of the borrowers.~~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 March 31, 2021, the allowance for credit losses as a percentage of nonperforming and restructured loans was 187.69%, 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.

Other real estate owned and repossessed assets totaled ~~$4.9~~$30.3 million at ~~June 30, 2020,~~March 31, 2021, compared to ~~$6.1~~$32.5 million at December 31, ~~2019.~~

~~Potential problem~~2020. 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, 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 ~~are performing~~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 ~~borrowers with a weakened financial condition, or which~~other real estate owned are ~~experiencing unfavorable trends in their financial condition, which causes management to have concerns as~~charged directly to the ~~ability~~allowance for credit losses. Any losses on bank premises designated to be sold are charged to operating expense at the time of ~~such borrowers~~transfer from premises to ~~comply with~~other real estate owned. Decreases in values of properties subsequent to their classification as other real estate owned are charged to operating expense.

Identifiable intangible assets and goodwill totaled $168.1 million and $168.9 million at March 31, 2021 and December 31, 2020, respectively.

Other assets includes the ~~existing repayment terms.~~cash surrender value of key-man life insurance policies. The ~~Company had approximately $8.0~~balance of the cash surrender value of key-man life insurance policies was $81.3 million ~~of these loans~~ at ~~June 30, 2020, compared to $13.7~~March 31, 2021 and $80.7 million at December 31, ~~2019. Potential problem loans~~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.

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 ~~not~~ included in ~~nonperforming~~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 the Company’s low income housing tax credit investments and restructured loans. In general, these loans are adequately collateralized and have no specific identifiable loss. Loans which are considered to have identifiable loss potential are placed on nonaccrual status, are allocated a specific allowance for loss or are directly charged-down, and are reported as nonperforming.new market tax credit investments.

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.

At ~~June 30, 2020,~~March 31, 2021, deposits totaled ~~$8.5~~$9.4 billion, an increase of ~~$1.0~~$1.3 billion or ~~13.4%~~16.2% from the December 31, ~~2019~~2020 total. The increase in deposits ~~were~~was primarily related to deposits of proceeds from the PPP and ~~inflow of existing customer deposits.~~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 ~~98.2%~~98.6% at ~~June 30, 2020~~March 31, 2021 and ~~98.4%~~98.2% at December 31, ~~2019.~~2020. Noninterest-bearing deposits to total deposits were ~~43.7%~~45.6% at ~~June 30, 2020,~~March 31, 2021, compared to ~~39.5%~~47.0% at December 31, ~~2019.~~2020.

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 ~~$8.1~~$3.8 million at ~~June 30, 2020,~~March 31, 2021, compared to $1.1 million at December 31, ~~2019.~~2020.

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 ~~$839.1~~$826.6 million, are pledged as collateral for the borrowings under the line of credit. As of ~~June 30,~~March 31, 2021 and December 31, 2020, the Company had ~~$3.0 million advanced~~no advances outstanding under the line of credit from FHLB, compared to no advances outstanding as of December 31, 2019. The current $3.0 million advance is for six-months at 0%. In addition, the Company has a revolving line of credit with another financial institution with the ability to draw up to $10.0 million with no advances outstanding. This line of credit has a variable rate based on prime rate minus 25 basis points and matures in the third quarter of 2020.FHLB.

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, ~~2019.~~2020.

Stockholders’ equity totaled ~~$1.0~~$1.1 billion at ~~June 30, 2020, compared to $1.0 billion at~~both March 31, 2021 and December 31, ~~2019.~~2020. In addition to net income of ~~$43.3~~$42.5 million, other changes in stockholders’ equity during the ~~six~~three months ended ~~June 30, 2020~~March 31, 2021 included ~~$534,000~~$1.3 million related to common stock issuances, ~~$832,000~~and $576,00 related to stock-based compensation, ~~$2.3 million change in accounting principle related to CECL and a $6.2 million increase in other comprehensive income,~~ that were partially offset by ~~$20.9~~$11.1 million in dividends, ~~and $3.1~~$5.4 million in ~~common stock repurchases.~~settlement of options in cash, and a $1.0 million decrease in other comprehensive income.

~~Except as set forth below, there~~There have been no significant changes in the Registrant’s disclosures regarding market risk since December 31, ~~2019,~~2020, the date of its most recent annual report to stockholders.

The Company seeks to reduce volatility in its net interest margin and net interest income through periods of changing interest rates. Accordingly, the Company’s interest rate sensitivity and liquidity are monitored on an ongoing basis by its Asset and Liability Committee (“ALCO”). The ALCO establishes risk measures, limits and policy guidelines for managing the amount of interest rate risk and its effect on net interest income and capital. A variety of tools are used to evaluate the magnitude of interest rate risk, the distribution of risk, the level of risk over time and the exposure to changes in certain interest rate relationships.

The ALCO also utilizes an earnings simulation model as a quantitative tool in measuring the amount of interest rate risk associated with changing market rates. The model quantifies the effects of various interest rate scenarios on projected net interest income over the next 12 months. These simulations incorporate assumptions regarding changes in interest rates and the maturity and repricing of earning assets and interest-bearing liabilities.

The ALCO uses gap analysis to monitor interest rate sensitivity based on the maturity and repricing frequencies of its earning assets and interest-bearing liabilities. This analysis indicates that the Company’s position is asset-sensitive, with a positive gap of $170 million for the zero to 12-month interval at June 30, 2020, which was 1.99% of total assets, compared to a positive gap of $172 million for the zero to 12-month interval at December 31, 2019, which was 2.30% of total assets.

The ALCO continuously monitors and manages the balance between interest rate-sensitive assets and liabilities. The objective is to manage the impact of fluctuating market rates on net interest income within acceptable levels. In order to meet this objective, management may lengthen or shorten the duration of assets or liabilities.

As of June 30, 2020, the model simulations projected that a 100 and 200 basis point increase would result in positive variance in net interest income of 0.48% and 1.88%, respectively, relative to the base case over the next 12 months.

As of December 31, 2019, the model simulations projected that a 100 and 200 basis point increase would result in positive variance in net interest income of 1.97% and 4.08%, respectively, relative to the base case over the next 12 months. Conversely, the model simulation projected that a decrease in interest rates of 100 basis points would result in a negative variance in net interest income of 2.84% relative to the base case over the next 12 months.

~~The~~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.~~procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act). Based on their evaluation they concluded that the disclosure controls and procedures of the Company are effective to ensure that information required to be disclosed by the Company in the reports filed or submitted by it under the Securities Exchange Act of 1934 is recorded, processed, summarized and reported, within the time periods specified in the applicable rules and forms.

~~The adoption of ASC 326 required~~Changes in Internal Control Over Financial Reporting. During the ~~implementation of new accounting policies and procedures, including enhancements~~period to ~~our information systems,~~ which ~~changed~~ this report relates, there have not been any changes in the Company’s internal controls over financial reporting ~~for~~(as defined in Rule 13a-15(f) and 15d-15(f) under the analysis of the allowance for credit losses and related disclosures. Other than the change related to the adoption of ASC 326, there were no changes during the period covered by this Quarterly Report on Form 10-Q in the Company’s internal controls over financial reportingExchange Act) that have materially affected, or are reasonably likely to materially affect, ~~those~~such controls.

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.

Except as set forth below, as of ~~June 30, 2020,~~March 31, 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, ~~2019:~~2020:

The ~~COVID-19 pandemic has impacted our business, and~~Durbin Amendment is a provision in the ~~ultimate impact on our business and financial results will depend on future developments, which are highly uncertain and cannot be predicted, including~~larger Dodd-Frank Act that gave the ~~scope and duration of the pandemic and actions taken by governmental authorities in response to the pandemic.~~

~~With the lack of precedent, we are unable to predict with a high level of confidence how the COVID-19 pandemic will affect our business.~~ The COVID-19 pandemic has negatively impacted the global economy, disrupted global supply chains, lowered equity market valuations, created significant volatility and disruption in financial markets, and increased unemployment levels. In addition, the pandemic has resulted in temporary closures of many businesses and the institution of social distancing. As a result, the demand for our products and services may be significantly impacted. Furthermore, the pandemic has influenced and could further influence the recognition of credit losses in our loan portfolios and has increased and could further increase our allowance for credit losses, particularly if businesses remain closed or otherwise adversely affected for an extended period of time, or even permanently. In addition, we are a lender for the Paycheck Protection Program ("PPP") of the Small Business Administration (SBA) and other SBA, Federal Reserve ~~or United States Treasury programs that have been or~~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 ~~be created in~~charge for debit card interchange fees. At December 31, 2020, the ~~future in response to~~Company’s assets did not exceed $10 billion but, at March 31, 2021, the ~~pandemic. These programs are new, the terms are subject to political influence and their effects on our business are uncertain.~~ ~~Through June 30, 2020, we approved 8,392 loans totaling approximately $825.1 million, net of unamortized processing fees of $26.2 million.~~ The extent to which the COVID-19 pandemic impacts our business, results of operations, and financial condition, as well as our regulatory capital and liquidity ratios, will depend on future developments, which are highly uncertain and cannot be predicted.

Due to the impacts of the COVID-19 pandemic, the Company has modified approximately $939.8 million in loans, most of which are 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. Consequently, it is reasonable to expect that when temporary regulatory accounting relief and payment modifications cease, there will be a marked increase in credit impairment and restructured loans. The timing and extent of such consequences are impossible 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.

Company’s assets did exceed $10 billion. Prior to the COVID-19 pandemic, there was ~~only a remote~~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 ~~any~~ reasonably foreseeable levels. To the extent the COVID-19 pandemic continues and the government response to it ~~continue in~~continues on the same or similar ~~manner,~~basis, it is likely the Company ~~has a much heightened possibility of exceeding~~will exceed $10 billion in total assets at December 31, ~~2020.~~2021. Pursuant to the Durbin ~~amendment~~Amendment of the Dodd-Frank Act, based on current run rates, this would trigger an approximate ~~loss~~reduction of annual pretax income from debit card interchange fees of between ~~$16 and $18~~$17 to $20 million ~~in subsequent years. The Company is developing strategies to avoid exceeding $10 billion in assets and the loss of interchange income, but the success of these strategies is uncertain.~~

Significant uncertainties as to future economic conditions exist, and we have taken deliberate actions in response. Additionally, the economic pressures have contributed to an increased provision for credit losses for the first half of 2020. We continue to monitor the impact of the COVID-19 pandemic closely, as well as any effects that may result from the CARES Act; however, the extent to which the COVID-19 pandemic will impact our operations and financial results during the remainder of 2020 is highly uncertain.beginning July 1, 2022.

Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized.
