BANCFIRST CORP /OK/

(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, 2024.

Basis of Presentation

The accompanying unaudited interim consolidated financial statements include the accounts of BancFirst Corporation, Council Oak Partners, LLC, BFC-PNC, LLC, BancFirst Insurance Services, Inc., Pegasus Bank ("Pegasus"), Worthington Bank ("Worthington") and BancFirst and its subsidiaries ("BancFirst"). The principal operating subsidiaries of BancFirst are BFTower, 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 consolidated financial statements and footnotes included in BancFirst Corporation’s Annual Report on Form 10-K for the year ended December 31, 2024, 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 assets and liabilities acquired in a business combination, including identifiable intangible assets. Such estimates and assumptions may change over time and actual amounts realized may differ from those reported.

Recent Accounting Pronouncements

Standards Not Yet Adopted:

In November 2024, the Financial Accounting Standards Board (“FASB“) issued Accounting Standards Update (“ASU”) 2024-03, “Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures” requiring disclosure of certain costs and expenses in the notes to financial statements. This ASU is effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. The amendments may be applied prospectively or retrospectively to all periods presented. The Company does not expect adoption of the standard to have a material impact on its consolidated financial statements.

In December 2023, FASB issued ASU No. 2023-09, “Income Taxes - Improvements to Income Tax Disclosures” requiring enhancements and further transparency to certain income tax disclosures, most notably the tax rate reconciliation and income taxes paid. This ASU is effective for annual periods beginning after December 15, 2024 on a prospective basis and retrospective application is permitted. The Company does not expect adoption of the standard to have a material impact on its consolidated financial statements.

(2) RECENT DEVELOPMENTS, INCLUDING MERGERS AND ACQUISITIONS

On May 20, 2025, the Company entered into an agreement to acquire American Bank of Oklahoma ("ABOK"), a privately held community bank headquartered in Collinsville, Oklahoma. ABOK has approximately $385 million in total assets, $280 million in loans, and $320 millionin deposits. The transaction is expected to close in the third quarter of 2025, subject to regulatory approvals and customary closing conditions. ABOK will operate under its present name until it is merged into BancFirst, which is expected to be in the fourth quarter of 2025.

(3) SECURITIES

The following table summarizes the amortized cost and estimated fair values of debt securities held for investment:

The following table summarizes the amortized cost and estimated fair values of debt securities available for sale:

(1) Primarily consists of FHLMC, FNMA, GNMA and mortgage backed securities through U.S. agencies.

The maturities of debt securities held for investment and available for sale are summarized in the following table using contractual maturities. Actual maturities may differ from contractual maturities due to obligations that are called or prepaid. For purposes of the maturity table, mortgage-backed securities, which are not due at a single maturity date, have been presented at their contractual maturity.

The following table is a summary of the Company’s book value of securities that were pledged as collateral for public funds on deposit, repurchase agreements and for other purposes as required or permitted by law:

There wereno sales of debt securities and thereforeno proceeds from sales or realized securities gains or losses on available for sale debt securities for the six months ended June 30, 2025 or June 30, 2024.

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

The following table summarizes debt securities with unrealized losses, segregated by the duration of the unrealized loss, at June 30, 2025 and December 31, 2024 respectively:

The Company has the ability and intent to hold the debt securities classified as held for investment until they mature, at which time the Company will receive full value for the debt securities. Furthermore, as of June 30, 2025 and December 31, 2024, the Company also had the ability and intent to hold the debt securities classified as available for sale for a period of time sufficient for a recovery of cost. The unrealized losses are due to increases in market interest rates over the yields available at the time the underlying debt securities were purchased. The fair value of those debt securities having unrealized losses is expected to recover as the securities approach their maturity date or repricing date or if market yields for such investments decline. The Company has no intent or requirement to sell before the recovery of the unrealized loss; therefore, no impairment loss was realized in the Company’s consolidated statement of comprehensive income.

(4) LOANS HELD FOR INVESTMENT AND ALLOWANCE FOR CREDIT LOSSES ON LOANS

Loans held for investment are summarized by portfolio segment as follows:

The Company's loans are currently 83% held by BancFirst and 17% held by Pegasus and Worthington. In addition, approximately 71% of the Company's loans are secured by real estate. Credit risk on loans is managed through limits on amounts loaned to individual and related borrowers, underwriting standards and loan monitoring procedures. The amounts and types of collateral obtained, if any, to secure loans are based upon the Company’s underwriting standards and management’s credit evaluation. Collateral varies, but may include real estate, equipment, accounts receivable, inventory, livestock and/or securities. The Company’s interest in collateral is secured through filing mortgages and liens, or by possession of the collateral.

The Company's portfolio segment descriptions and the weighted average remaining life of portfolio segments are disclosed in Note (5) to the Company's Annual Report on Form 10-K for the year ended December 31, 2024.

Other Real Estate Owned and Repossessed Assets and Loan Modifications

The following is a summary of other real estate owned ("OREO") and repossessed assets:

During the six months ended June 30, 2025 the Company foreclosed on a construction and development real estate loan and recorded $15.6 million in OREO, which was the primary reason for the increase in OREO.

In addition, as of both June 30, 2025 and December 31, 2024, OREO included a commercial real estate property recorded at approximately $30.7 million and $28.1 million, respectively. The increase for this commercial real estate property was due to tenant improvements during the six months ended June 30, 2025. Rental income for this property is included in other noninterest income on the consolidated statements of comprehensive income. Operating expense for this property is included in net expense from other real estate owned in noninterest expense on the consolidated statements of comprehensive income.

This property had the following rental income and operating expenses for the periods presented.

During the six months ended June 30, 2025, the Company sold property held in other real estate owned for a total loss of $79,000, compared to a total gain of $1.3 million in thesix months ended June 30, 2024.

The Company charges interest on principal balances outstanding on modified loans during deferral periods. The current and future financial effects of the recorded balance of loans considered to be modified during the period were not material. The recorded balance of loans modified during the six months ended June 30, 2025 was approximately$3.6 million compared to $14.8 million during the year ended December 31, 2024.

Nonaccrual loans

The Company didnot recognize any interest income on nonaccrual loans for either the six months ended June 30, 2025 or 2024. In addition, all loans identified as nonaccrual loans have related allowances for credit losses at June 30, 2025 and December 31, 2024, respectively. Had nonaccrual loans performed in accordance with their original contractual terms, the Company would have recognized additional interest income of approximately $2.3 millionfor the six months ended June 30, 2025 and approximately $1.8 million for thesix months ended June 30, 2024.

Nonaccrual loans guaranteed by government agencies totaled approximately $9.5 million at June 30, 2025 and approximately $9.0 million at December 31, 2024.

The following table is a summary of amounts included in nonaccrual loans, segregated by portfolio segment.

Loans are considered past due if the required principal and interest payments have not been received as of the date such payments were due. The following tables present an age analysis of the Company's loans held for investment:

Credit Quality Indicators

The Company considers credit quality indicators to monitor the credit risk in the loan portfolio including volume and severity of loan delinquencies, nonaccrual loans, internal grading of loans, historical credit loss experience and economic conditions. These indicators are reviewed and updated regularly throughout the year. An internal risk grading system is used to indicate the credit risk of loans. The loan grades used by the Company are for internal risk identification purposes and do not directly correlate to regulatory classification categories or any financial reporting definitions. The general characteristics of the risk grades and the table summarizing the Company’s gross loans held for investment by year of origination and internally assigned credit grades as of December 31, 2024, are disclosed in Note (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

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

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

The following tables summarize the Company's gross charge-offs by year of origination for the periods indicated:

Allowance for Credit Losses Methodology

The Company determines its provision for credit losses and allowance for credit losses using the current expected credit loss methodology that is referred to as the current expected credit loss ("CECL") model. The allowance for current expected credit losses is measured on a collective (pool) basis when similar risk characteristics exist. The allowance for credit losses methodology is disclosed in Note (5) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

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

Purchased Credit Deteriorated Loans

The Company has previously purchased loans, for which there was, at acquisition, evidence of more than insignificant deterioration of credit quality since origination. The Company did not purchase credit-deteriorated loans during the six month period ended June 30, 2025 or June 30, 2024.

Collateral Dependent Loans

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 six months ended June 30, 2025 and 2024, no material amount of interest income was recognized on collateral-dependent loans subsequent to their classification as collateral-dependent. The following tables summarize collateral-dependent gross loans held for investment by collateral type and the related specific allocation as follows:

Non-Cash Transfers from Loans and Premises and Equipment

Transfers from loans and premises and equipment to OREO and repossessed assets are non-cash transactions, and are not included in the consolidated statements of cash flow.

Transfers from loans and premises and equipment to OREO and repossessed assets during the periods presented are summarized as follows:

(5) INTANGIBLE ASSETS AND GOODWILL

The following is a summary of intangible assets as of the date listed:

The following is a summary of goodwill by business segment:

Additional information for intangible assets can be found in Note (7) to the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

(6) SUBORDINATED DEBT

In 2004, BFC Capital Trust II (“BFC II”), issued $26 million of aggregate liquidation amount of 7.20% Cumulative Trust Preferred Securities (the “Cumulative Trust Preferred Securities”) to other investors. 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 arepayable 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 have been callable at par, in whole or in part, since 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 qualify as Tier 2 capital under bank regulatory guidelines. The net proceeds to the Company from the sale of the Subordinated Notes were approximately $59.15 million net of commissions and offering expenses. The Company used the proceeds from the sale of the Subordinated Notes for general corporate purposes. The Subordinated Notes 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.

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”

(eachas 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.

(7) STOCK-BASED COMPENSATION

On May 25, 2023, the shareholders of the Company adopted the BancFirst Corporation 2023 Restricted Stock Unit Plan (the "RSU Plan"). The RSU Plan was effective as of June 1, 2023 and for a period often years thereafter. The RSU Plan will continue in effect after such ten-year period until all matters relating to the payment of awards and administration of the RSU Plan have been settled. At June 30, 2025 there were 447,175 shares available for future grants. The restricted stock units ("RSU's") vest beginningtwo years from the date of grant at the rate of 20% per year forfive years. The RSU's are settled and distributed as of each vesting date. The fair value of each RSU granted is equal to the market price of the Company’s stock at the date of grant.

The following table is a summary of the activity under the Company's RSU plan.

The Company has had the BancFirst Corporation Directors’ Deferred Stock Compensation Plan (the “Deferred Stock Compensation Plan”) since May 1999. As of June 30, 2025, there are 31,459 shares available for future issuance under the Deferred Stock Compensation Plan. The Deferred Stock Compensation Plan will terminate on December 31, 2030, if not extended. Under the plan, directors and members of the community advisory boards of the Company and its subsidiaries may defer up to 100% of their board fees. They are credited for each deferral with a number of stock units based on the current market price of the Company’s stock, which accumulate in an account until such time as the director or community board member terminates serving as a board member. Shares of common stock of the Company are then distributed to the terminating director or community board member based upon the number of stock units accumulated in his or her account. There were 6,462 and 5,022 shares of common stock distributed from the Deferred Stock Compensation Plan during the six months ended June 30, 2025 and 2024, respectively.

A summary of the accumulated stock units under the Deferred Stock Compensation Plan is as follows:

The Company terminated the BancFirst Corporation Stock Option Plan (the “Employee Plan”) on June 1, 2023. The remaining options will continue to vest and are exercisable beginning four years from the date of grant at the rate of 25% per year forfour years, and expire no later than the end offifteen years from the date of grant.

The Company terminated the BancFirst Corporation Non-Employee Directors’ Stock Option Plan (the “Non-Employee Directors’ Plan”) on June 1, 2023. The remaining options will continue to vest and are exercisable beginningone year from the date of grant at the rate of 25% per year forfour years, and expire no later than the end offifteen years from the date of grant.

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

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

The Company currently uses newly issued shares for stock-based compensation plans, 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 or restricted stock units in cash on a limited basis at the discretion of the Company. The Company hadno cash settlements during the six months ended June 30, 2025 or June 30, 2024.

Stock-based compensation expense is charged to salaries and benefits expense on the Consolidated Statements of Comprehensive Income. The components of stock-based compensation expense for all share-based compensation plans and related tax benefits are as follows:

The Company amortizes the unearned stock-based compensation expense over the remaining vesting period of approximately five years for unvested stock options andsix years for unvested RSU's. The following table shows the unearned stock-based compensation expense for unvested stock options and unvested RSU's:

(8) STOCKHOLDERS’ EQUITY

The Company has adopted a Stock Repurchase Program (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 issuance of stock related to stock-based compensation plans, 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 is determined by management and approved by the Company’s Executive Committee.

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

BancFirst Corporation, BancFirst, Pegasus and Worthington are subject to risk-based capital guidelines issued by the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation (“FDIC”). These guidelines are used to evaluate capital adequacy and involve both quantitative and qualitative evaluations of 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 consolidated financial statements. The Company believes that as of June 30, 2025, BancFirst Corporation, BancFirst, Pegasus and Worthington each 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, 2025, BancFirst, Pegasus and Worthington were classified by the Federal Reserve as “well capitalized” under the prompt corrective action provisions. The Common Equity Tier 1 Capital of BancFirst Corporation, BancFirst, Pegasus and Worthington includes common stock and related paid-in capital and retained earnings. In connection with the adoption of the Basel III Capital Rules, the election was made to opt-out of the requirement to include most components of accumulated other comprehensive income in Common Equity Tier 1 Capital. Common Equity Tier 1 Capital for BancFirst Corporation, BancFirst, Pegasus and Worthington is reduced by goodwill and other intangible assets, net of associated deferred tax liabilities. The Company’s trust preferred securities qualify as Tier 1 capital and its Subordinated Notes qualify as Tier 2 capital. BancFirst, Pegasus and Worthington have had no events or conditions that management believes would materially change their category under capital requirements existing as of the report dates.

(9) NET INCOME PER COMMON SHARE

Basic and diluted net income per common share are calculated as follows:

The following table shows the number of options and RSU's that were excluded from the computation of diluted net income per common share for each period because they were anti-dilutive for the period:

(10) FAIR VALUE MEASUREMENTS

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

FASB Accounting Standards Codification (“ASC”) Topic 820 establishes a fair value hierarchy for valuation inputs that gives the highest priority to quoted prices in active markets for identical assets or liabilities and the lowest priority to unobservable inputs. The fair value hierarchy is as follows:

•

Level 1 Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities in active markets.

•

Level 2 Inputs to the valuation methodology include quoted prices for similar assets and liabilities in active markets, and inputs that are observable for the asset and liability, either directly or indirectly, for substantially the full term of the financial instrument.

•

Level 3 Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities include financial instruments whose values are determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant judgment or estimation. This category includes certain collaterally dependent loans, repossessed assets, other real estate owned, goodwill and other intangible assets.

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

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

Debt Securities Available for Sale

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

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

Derivatives

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

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

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, 2025, and the year ended December 31, 2024, the Company did not transfer any debt securities.

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; the instruments are not measured at fair value on an ongoing basis but are subject to fair value adjustments in certain circumstances (for example, when there is evidence of impairment). These financial assets and financial liabilities are reported at fair value utilizing Level 3 inputs.

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

Collateral dependent loans are reported at the fair value of the underlying collateral if repayment is dependent on liquidation of the collateral. When the Company determines that foreclosure is probable or when the borrower is experiencing financial difficulty at the reporting date and repayment is expected to be provided substantially through the operation or sale of the collateral, expected credit 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. These nonrecurring fair values do not represent all assets, only those assets that have been adjusted during the reporting 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 are used to estimate the fair value of each class of financial instruments:

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

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

Federal Funds Sold

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

Debt Securities Held for Investment

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

Loans Held for Sale

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

Loans Held for Investment

To determine the fair value of loans held for investment, 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:

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

The Company hasno non-financial assets or non-financial liabilities measured at fair value on a recurring basis. In addition, the Company has no non-financial liabilities measured at fair value on a nonrecurring basis. Non-financial assets measured at fair value on a nonrecurring basis include intangible assets. The intangible assets are evaluated at least annually for impairment. The overall levels of non-financial assets measured at fair value on a nonrecurring basis werenot considered to be significant to the Company at June 30, 2025 or December 31, 2024.

(11) DERIVATIVE FINANCIAL INSTRUMENTS

The Company enters into oil and gas swaps and options contracts to accommodate the business needs of its customers. Upon the origination of an oil or gas swap or option contract with a customer, to mitigate the exposure to fluctuations in oil and gas prices, the Company simultaneously enters into an offsetting contract with a counterparty. These derivatives are not designated as hedged instruments and are recorded on the Company's consolidated balance sheet at fair value and are included in other assets. The Company's derivative financial instruments require a daily margin to be posted, which fluctuates with oil and gas prices. At June 30, 2025 and December 31, 2024, the Company had a margin asset included in other assets in the amount of $3.6 million and $463,000, respectively.

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

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

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

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

Balance Sheet Offsetting

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