SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Nature of Operations The Company is a financial holding company, headquartered in Baton Rouge, Louisiana that provides full banking services, excluding trust services, through its wholly-owned banking subsidiary, Investar Bank, National Association, a national bank, primarily to meet the needs of individuals, professionals and small to me dium-sized businesses. The Company’s primary markets are in south Louisiana, Texas and Alabama. At March 31, 2026 , the Company operated 20 full service branches located in Louisiana, ten full service branches located in Texas and six full service branches located in Alabama and ha d 431 full-time e quivalent employees. Basis of Presentation The accompanying unaudited consolidated financial statements of the Company have been prepared in accordance with GAAP for interim financial information and the instructions to Form 10 -Q and Article 10 of Regulation S- X. Accordingly, they do not include information or footnotes necessary for a complete presentation of financial position, results of operations, and cash flows in conformity with GAAP. However, in the opinion of management, all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the financial statements have been included. The results of operations for the three month period ended March 31, 2026 are not necessarily indicative of the results that may be expected for the entire fiscal year. These statements should be read in conjunction with the Company’s audited consolidated financial statements for the year ended December 31, 2025 , including the notes thereto, which were included as part of the Company’s Annual Report. Prior period consolidated financial statements are reclassified whenever necessary to conform to the current period presentation. No reclassifications of prior period balances were material to the consolidated financial statements. Principles of Consolidation The consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, the Bank. All significant intercompany accounts and transactions have been eliminated in consolidation. Segment Reporting The Company determined that all of its banking operations serve a similar customer base, offer similar products and services, and are managed through similar processes. Therefore, the Company’s banking operations are aggregated into one reportable operating segment, which generates income principally from interest on loans and, to a lesser extent, securities investments, as well as from fees charged in connection with various loan and deposit services. The CODM is the Chief Executive Officer, who for the purposes of assessing performance, making operating decisions, and allocating Company resources, regularly reviews net income as reported in the accompanying consolidated statements of income. The level of disaggregation and amounts of significant segment income and expenses that are regularly provided to the CODM are the same as those presented in the accompanying consolidated statements of income. Likewise, the measure of segment assets is reported on the accompanying consolidated balance sheets as total assets. Use of Estimates The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities at the date of the financial statements as well as the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates, and such differences could be material. Material estimates that are particularly susceptible to significant change relate to the determination of the ACL. While management uses available information to recognize credit losses on loans, future additions to the allowance may be necessary based on changes in economic conditions, changes in conditions of borrowers’ industries or changes in the condition of individual borrowers. Because of these factors, it is reasonably possible that the ACL may change materially in the near term. However, the amount of change that is reasonably possible cannot be estimated. Other estimates that are susceptible to significant change in the near term relate to the allowance for off-balance sheet credit losses, the fair value of stock-based compensation awards, the determination of an ACL for investment securities, and the fair value of financial instruments and goodwill. A changing interest rate environment, elevated levels of inflation and changing U.S. trade and tariff policies have made certain estimates more challenging, including those discussed above. 10 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Accounting Standards Adopted in 2026 FASB ASC Topic 326 “ Financial Instruments - Credit Losses (Topic 326 ): Purchased Loans. ” Update No. 2025 - 08 ( “ ASU 2025 - 08 ” ) . In November 2025, the FASB issued ASU 2025 - 08, which expands the scope of the “gross‑up” method, formerly applicable only to PCD assets, to include acquired non‑PCD loans that meet certain criteria, now referred to as PSLs. Under this model, an ACL is recognized at acquisition, offsetting the loan’s amortized cost basis, thereby eliminating the day- one provision expense previously required for non‑PCD assets. PSLs are defined as non‑PCD loans acquired either (i) through a business combination, or (ii) purchased more than 90 days after origination when the acquirer was not involved in origination. ASU 2025 - 08 is effective for annual reporting periods beginning after December 15, 2026, including interim reporting periods, and must be applied prospectively. Early adoption is permitted in interim or annual reporting periods in which financial statements have not yet been issued. An entity that adopts the amendments in an interim reporting period may apply them as of the beginning of that interim reporting period or the beginning of the annual reporting period that includes that interim reporting period. The Company early adopted ASU 2025 - 08 for the annual reporting period beginning on January 1, 2026. On January 1, 2026, for PSLs acquired from WFB, the Company established an ACL of $ 11.6 million and recorded it as part of their initial amortized cost. For additional information, see Note 2. Business Combinations and Note 5. Loans and Allowance for Credit Losses. Recent Accounting Pronouncements FASB ASC Topic 220 “ Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures: Disaggregation of Income Statement Expenses ” Update No. 2024 - 03 ( “ ASU 2024 - 03 ”). In November 2024, the FASB issued ASU 2024 - 03, which requires disaggregated disclosure of income statement expenses in a tabular format in the notes of the financial statements for public business entities. ASU 2024 - 03 is effective on a prospective basis for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027, with early adoption and retrospective application permitted. ASU 2024 - 03 is not expected to have a significant impact on our financial statements. FASB ASC Topic 815 “ Derivatives and Hedging (Topic   815 ): Hedge Accounting Improvements. ” Update No. 2025 - 09 ( “ ASU 2025 - 09 ” ) . In November 2025, the FASB issued ASU 2025 - 09, which aligns hedge accounting more closely with an entity’s economic risk management practices. Key amendments include (i) to allow designating a variable price component of a nonfinancial forecasted purchase or sale as the hedged risk, (ii) to allow grouping individual forecasted transactions with similar ( not identical) risk exposures, (iii) a new model for hedging forecasted interest on variable-rate debt, enabling changes in index or tenor without dedesignation, subject to simplifying assumptions, and (iv) additional clarifications related to hedge accounting of nonfinancial components, net written options, and dual-hedge strategies. ASU 2025 - 09 is effective on a prospective basis for annual reporting periods beginning after December 15, 2026. Early adoption is permitted. ASU 2025 - 09 is not expected to have a significant impact on our financial statements. 11 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 2. BUSINESS COMBINATIONS On January 1, 2026, the Company completed the acquisition of WFB and its wholly-owned subsidiary, FNB, headquartered in Wichita Falls, Texas, with six additional branches serving the surrounding areas. All of the issued and outstanding shares of WFB common stock were converted into aggregate merger consideration consisting of $ 7.2 million in cash and 3,955,272 shares of Company common stock for an aggregate transaction value of $ 112.9 million. After fair value adjustments, the acquisition added $ 1.15 billion in total assets, including $ 950.2 million in net loans, and $ 1.02 billion in deposits. As consideration paid was in excess of the net fair value of acquired assets, the Company recorded $ 18.0 million of goodwill, none of which is anticipated to be deductible for tax purposes. Goodwill resulted from a combination of synergies and cost savings, and further expansion into Texas. The table below shows the allocation of the consideration paid for WFB’s common equity to the acquired identifiable assets and liabilities assumed and the goodwill generated from the transaction (dollars in thousands). The fair values listed below are subject to refinement for up to one year after the closing date of the acquisition as additional information becomes available. Preliminary purchase price allocation: Shares of Investar common stock to be issued for shares of WFB common stock 3,955,272 Price per share, based on Investar common stock price as of December 31, 2025 $ 26.72 Fair value of Investar common stock issued $ 105,685 Cash consideration 7,202 Total consideration $ 112,887 Fair value of assets acquired: Cash and cash equivalents $ 82,784 Investment securities 51,455 Net loans 950,235 Nonmarketable equity securities 3,621 Bank premises and equipment 19,834 Core deposit intangible asset 13,570 BOLI 13,751 Other assets 10,343 Total assets acquired 1,145,593 Fair value of liabilities acquired: Deposits 1,023,365 Repurchase agreements 1,193 Notes payable 9,163 Other borrowings 15,051 Other liabilities 1,936 Total liabilities assumed 1,050,708 Fair value of net assets acquired 94,885 Goodwill $ 18,002 Loans The Company adopted ASU 2025 - 08 for the annual reporting period beginning on January 1, 2026. Accordingly, the initial estimate of expected credit losses recognized in the ACL included both PCD and non-PCD loans which were deemed PSLs. The following table includes principal balance and the fair value of the loans acquired from WFB (dollars in thousands). Principal Balance Acquired Non-Credit Premium/(Discount) ACL Fair Value of Net Loans PCD loans $ 1,441 $ ( 97 ) $ ( 143 ) $ 1,201 PSL loans 982,806 ( 22,213 ) ( 11,559 ) 949,034 Total $ 984,247 $ ( 22,310 ) $ ( 11,702 ) $ 950,235 The Company has determined it was impracticable to disclose stand-alone revenues and net income for legacy WFB since January 1, 2026 due to the streamlining and integration of the operating activities during the first quarter of 2026. The Company has also determined it was impracticable to include pro forma information for the WFB acquisition due to the cost versus benefit of including such disclosures. Acquisition Expense Acquisition related costs of $ 1.7 million and $ 0.2 million are included in acquisition expenses in the accompanying consolidated statements of income for the three months ended March 31, 2026 and 2025 , respectively. These costs include system conversion and integrating operations charges and legal and consulting expenses. 12 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 3. EARNINGS PER COMMON SHARE Basic earnings per common share is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted earnings per common share is computed by using net income available to common shareholders plus dividends declared on dilutive convertible preferred stock, divided by the sum of 1) the weighted average number of shares determined for the basic earnings per common share computation, 2) the dilutive effect of stock-based compensation using the treasury stock method, and 3 ) the dilutive effect of convertible preferred stock using the if-converted method. The following is a summary of the information used in the computation of basic and diluted earnings per common share for the three months ended March 31, 2026 and 2025 (in thousands, except share and per share data).

The Company intends to hold these securities either until maturity or a forecasted recovery, and it is more likely than not that the Company will not have to sell the securities before the recovery of their amortized cost basis. The unrealized losses in obligations of state and political subdivisions were caused by interest rate changes. These securities generally benefit from stable, dedicated revenue sources and a legal framework that prioritizes bondholder payments, which significantly mitigates credit risk. The unrealized losses in mortgage-backed securities were caused by interest rate changes. The Company expects to recover the amortized cost basis over the term of the securities. These securities are either guaranteed by the U.S. government or by a government sponsored enterprise and are generally considered to be risk-free. Due to the nature of the investments, current market prices, and the current interest rate environment, the Company determined that these declines were not attributable to credit losses at March 31, 2026 or December 31, 2025 . 15 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The amortized cost and approximate fair value of investment debt securities, by contractual maturity, are shown below as of March 31, 2026 (dollars in thousands).

At March 31, 2026 , securities with a carrying value of $ 134.8 million were pledged to secure certain deposits, borrowings, and other liabilities, compared to $ 75.6 million in pledged securities at December 31, 2025 . Equity Securities Equity securities at fair value include marketable securities in corporate stocks and mutual funds and totaled $ 3.5 million and $ 3.4 million at March 31, 2026 and December 31, 2025 , respectively. Nonmarketable equity securities primarily consist of FHLB stock and FRB stock. Members of the FHLB and FRB are required to own a certain amount of stock based on the level of borrowings and other factors and may invest in additional amounts. FHLB stock and FRB stock are carried at cost, restricted as to redemption, and periodically evaluated for impairment based on the ultimate recovery of par value. Both cash and stock dividends are reported as income. Nonmarketable equity securities also include investments in other correspondent banks including Independent Bankers Financial Corporation and First National Bankers Bank stock. These investments are carried at cost which approximates fair value. The balance of nonmarketable equity securities at March 31, 2026 and December 31, 2025 was $ 21.4 million and $ 17.0 million, respectively. 16 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 5.

Loans are placed on nonaccrual status when, in management’s opinion, the borrower may be unable to meet payment obligations as they become due. In determining whether or not a borrower may be unable to meet payment obligations for each class of loans, the borrower’s debt service capacity is considered through the analysis of current financial information, if available, and/or current information with regard to the collateral position. Loans are placed on nonaccrual status when (i) principal or interest has been in default for a period of 90 days or more unless the loan is both well secured and in the process of collection or (ii) full payment of principal and interest is not expected. Loans may be placed on nonaccrual status regardless of whether or not such loans are considered past due. When interest accrual is discontinued, all unpaid accrued interest is reversed. Interest income on nonaccrual loans is recognized only to the extent that cash payments are received in excess of principal due. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and payment of future principal and interest amounts contractually due are reasonably assured, which is typically evidenced by a sustained period (at least six months) of repayment performance by the borrower. No material interest income was recognized in the consolidated statements of income on nonaccrual loans for the three months ended March 31, 2026 and 2025 . Collateral Dependent Loans Collateral dependent loans are loans for which the repayments, on the basis of the Company ’ s assessment at the reporting date, are expected to be provided substantially through the operation or sale of the collateral and the borrower is experiencing financial difficulty. Loans that do not share risk characteristics are excluded from the loan pools and evaluated on an individual basis, and the Company has determined to evaluate collateral dependent loans individually for impairment. The ACL for collateral dependent loans is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the present value of expected cash flows from the operation of the collateral. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized costs basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The Company ’ s collateral dependent loans include all nonaccrual loans shown in the tables above at March 31, 2026 and December 31, 2025 . The types of collateral that secure collateral dependent loans are discussed under “Portfolio Segment Risk Factors” below. 18 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Portfolio Segment Risk Factors The following describes the risk characteristics relevant to each of the Company’s loan portfolio segments. Constructio n and Development - Construction and development loans are generally made for the purpose of acquisition and development of land to be improved through the construction of commercial and residential buildings. The successful repayment of these types of loans is generally dependent upon a commitment for permanent financing from the Company, or from the sale of the constructed property. These loans carry more risk than commercial or residential real estate loans due to the dynamics of construction projects, changes in interest rates, the long-term financing market, and state and local government regulations. One such risk is that loan funds are advanced upon the security of the property under construction, which is of uncertain value prior to the completion of construction. Thus, it is more difficult to evaluate accurately the total loan funds required to complete a project and to calculate related loan-to-value ratios. The Company attempts to minimize the risks associated with construction lending by limiting loan-to-value ratios as described above. In addition, as to speculative development loans, the Company generally makes such loans only to borrowers that have a positive pre-existing relationship with us. The Company manages risk by using specific underwriting policies and procedures for these types of loans and by avoiding excessive concentrations in any one business or industry. Construction and development loans are primarily secured by residential and commercial properties, which are under construction and/or redevelopment. 1 - 4 Family - The 1 - 4 family portfolio consists of fixed-rate and adjustable-rate residential mortgage loans to consumers to finance a primary residence. The majority of these loans are secured by first liens on residential properties located in the Company’s market areas and carry risks associated with the creditworthiness of the borrower and changes in the value of the collateral and loan-to-value-ratios. The adjustable-rate mortgage loans provide an initial fixed interest rate, generally for three, five or seven years, and then adjust annually thereafter and amortize over a period of up to 30 years. Adjustable-rate mortgage loans generally present different credit risks than fixed-rate mortgage loans primarily because the underlying debt service payments of the borrowers increase as interest rates increase, thereby increasing the potential for delinquency and default. The Company manages these risks through policies and procedures such as limiting loan-to-value ratios at origination, employing experienced underwriting personnel, requiring standards for appraisers, and not making subprime loans. In the third quarter of 2023, the Company exited the consumer mortgage origination business. Multifamily - Multifamily loans are normally made to real estate investors to support permanent financing for multifamily residential income producing properties that rely on the successful operation of the property for repayment. This management mainly involves property maintenance and collection of rents due from tenants. This type of lending carries a lower level of risk compared to other commercial lending. In addition, underwriting requirements for multifamily properties are stricter than for other nonowner-occupied property types. The Company manages this risk by avoiding concentrations with any particular customer. Multifamily loans are primarily secured by first liens on multifamily real estate. Farmland - Farmland loans are often for land improvements related to agricultural endeavors and may include construction of new specialized facilities. These loans are usually repaid through the conversion to permanent financing, or if scheduled loan amortization begins, for the long-term benefit of the borrower’s ongoing operations. Underwriting generally involves intensive analysis of the financial strength of the borrower and guarantor, liquidation value of the subject collateral, the associated unguaranteed exposure, and any available secondary sources of repayment, with the greatest emphasis given to a borrower’s capacity to meet cash flow coverage requirements as set forth by Company policies. Farmland loans are primarily secured by raw land. Commercial Real Estate - Commercial real estate loans are extensions of credit secured by owner occupied and nonowner-occupied collateral. Underwriting generally involves intensive analysis of the financial strength of the borrower and guarantor, liquidation value of the subject collateral, the associated unguaranteed exposure, and any available secondary sources of repayment, with the greatest emphasis given to a borrower’s capacity to meet cash flow coverage requirements as set forth by Company policies. Commercial real estate loans typically depend on the successful operation and management of the businesses that occupy these properties or the financial stability of tenants occupying the properties. Nonowner-occupied commercial real estate loans typically are dependent, in large part, on the owner’s ability to rent the property and the ability of the tenants to pay rent, whereas owner-occupied commercial real estate loans typically are dependent, in large part, on the success of the owner’s business. General market conditions and economic activity may impact the performance of these types of loans, including fluctuations in the value of real estate, new job creation trends, and tenant vacancy rates. The Company attempts to limit risk by analyzing a borrower’s cash flow and collateral value on an ongoing basis. The Company also typically requires personal guarantees from the principal owners of the property, supported by a review of their personal financial statements, as an additional means of mitigating risk. The Company manages risk by avoiding concentrations in any one business or industry. Commercial real estate loans are primarily secured by retail shopping facilities, office and industrial buildings, healthcare facilities, warehouses, and various special purpose commercial properties. 19 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Com mercial and Industrial - Commercial and industrial loans receive similar underwriting treatment as commercial real estate loans in that the repayment source is analyzed to determine its ability to meet cash flow coverage requirements as set forth by Company policies. Repayment of these loans generally comes from the generation of cash flow as the result of the borrower’s business operations. Commercial lending generally involves different risks from those associated with commercial real estate lending or construction lending. Although commercial loans may be collateralized by equipment or other business assets (including real estate, if available as collateral), the repayment of these types of loans depends primarily on the creditworthiness and projected cash flow of the borrower (and any guarantors). Thus, the general business conditions of the local economy and the borrower’s ability to sell its products and services, thereby generating sufficient operating revenue to repay us under the agreed upon terms and conditions, are the chief considerations when assessing the risk of a commercial loan. The liquidation of collateral, if any, is considered a secondary source of repayment because equipment and other business assets may, among other things, be obsolete or of limited resale value. The Company actively monitors certain financial measures of the borrower, including advance rate, cash flow, collateral value and other appropriate credit factors. Commercial and industrial loans also include public finance loans made to governmental entities, which can be taxable or tax-exempt, and are generally repaid using pledged revenue sources including income tax, property tax, sales tax, and utility revenue, among other sources. Commercial and industrial loans are primarily secured by accounts receivable, inventory and equipment. Consumer - Consumer loans are offered by the Company in order to provide a full range of retail financial services to its customers and include auto loans, credit cards, and other consumer installment loans. Typically, the Company evaluates the borrower’s repayment ability through a review of credit scores and an evaluation of debt to income ratios. Repayment of consumer loans depends upon key consumer economic measures and upon the borrower’s financial stability and is more likely to be adversely affected by divorce, job loss, illness and personal hardships than repayment of other loans. A shortfall in the value of any collateral also may pose a risk of loss to the Company for these types of loans. Consumer loans include loans primarily secured by vehicles and unsecured loans. Credit Quality Indicators Loans are categorized into risk categories based on relevant information about the ability of borrowers to service their debt, such as current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The following definitions are utilized for risk ratings, which are consistent with the definitions used in supervisory guidance: Pass - Loans not meeting the criteria below are considered Pass. These loans have higher credit characteristics and financial strength. The borrowers at least generate profits and cash flow that are in line with peer and industry standards and have debt service coverage ratios above loan covenants and policy guidelines. For some of these loans, a guaranty from a financially capable party mitigates characteristics of the borrower that might otherwise result in a lower grade. Special Mention - Loans classified as Special Mention possess some credit deficiencies that need to be corrected to avoid a greater risk of default in the future. For example, financial ratios relating to the borrower may have deteriorated. Often, a Special Mention categorization is temporary while certain factors are analyzed or matters addressed before the loan is re-categorized as either Pass or Substandard. Substandard - Loans classified as Substandard are inadequately protected by the current net worth and paying capacity of the borrower or the liquidation value of any collateral. If deficiencies are not addressed, it is likely that this category of loan will result in the Bank incurring a loss. Where a borrower has been unable to adjust to industry or general economic conditions, the borrower’s loan is often categorized as Substandard. Doubtful - Loans classified as Doubtful have all the weaknesses inherent in those classified as Substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loss - Loans classified as Loss are considered uncollectible and of such little value that their continuance as recorded assets is not warranted. This classification does not mean that the assets have absolutely no recovery or salvage value, but rather it is not practical or desirable to defer writing off these assets. 20 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The tables below present the Company’s loan portfolio by year of origination, category, and credit quality indicator as of March 31, 2026 and December 31, 2025 (dollars in thousands).

Loan Participations and Sold Loans Loan participations and whole loans sold to and serviced for others are not included in the accompanying consolidated balance sheets, the balances of which were $ 47.9 million and $ 44.7 million at March 31, 2026 and December 31, 2025 , respectively. The total unpaid principal balances of loans where participating interests have been sold were a pproximate ly $ 229.6 million and $ 239.2 million at March 31, 2026 and December 31, 2025 , respectively. Loans to Related Parties In the ordinary course of business, the Company makes loans to related parties including its executive officers, principal stockholders, directors and their immediate family members, as well as to companies of which these individuals are principal owners. Loans outstanding to such related party borrowers amounted to approximately $ 34.3 million and $ 34.7 million as of March 31, 2026 and December 31, 2025 , respectively. No related party loans were classified as nonperforming or nonaccrual at March 31, 2026 or December 31, 2025 . The table below shows the aggregate principal balance of loans to such related parties as of the dates presented (dollars in thousands). March 31, 2026 December 31, 2025 Balance, beginning of period $ 34,749 $ 43,647 New loans/changes in relationship 63 231 Repayments/changes in relationship ( 490 ) ( 9,129 ) Balance, end of period $ 34,322 $ 34,749 Allowance for Credit Losses The CECL methodology requires that lifetime expected credit losses be recorded at the time the financial asset is originated or acquired, and be adjusted each period as a provision for credit losses for changes in expected lifetime credit losses. The Company developed a CECL model methodology that calculates expected credit losses over the life of the portfolio by analyzing the composition, characteristics and quality of the loan portfolio, as well as prevailing economic conditions and forecasts. The CECL calculation estimates credit losses using a combination of discounted cash flow and remaining life analyses, which is a type of loss rate methodology that uses an average loss rate and applies it to future expected outstanding balances of the pool. Management has determined that four quarters represents a reasonable and supportable forecast period. To the extent the lives of the loans in the portfolio extend beyond the period for which a reasonable and supportable forecast can be made, when necessary, the model reverts back to the historical loss rates adjusted for qualitative factors related to current conditions using a four -quarter reversion period. The Company evaluates the adequacy of the ACL on a quarterly basis. The ACL is comprised of reserves measured on a collective (pool) basis based on a lifetime loss-rate model when similar risk characteristics exist. For each pool of loans, the Company evaluates and applies qualitative adjustments to the calculated ACL based on several factors, including, but not limited to, changes in current and expected future economic conditions, changes in the nature and volume of the portfolio, changes in levels of concentrations, changes in the volume and severity of past due loans, changes in lending policies and personnel, changes in the competitive and regulatory environment of the banking industry, and changes in other external factors. Loans that do not share similar risk characteristics with other loans are excluded from the loan pools and individually evaluated for impairment. For collateral dependent loans where the borrower is experiencing financial difficulty, which the Company evaluates independently from the loan pool, the expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, which is based on third party appraisals. Individually evaluated loans that are not collateral dependent are evaluated based on a discounted cash flow methodology. Credits deemed uncollectible are charged to the ACL. Provisions for credit losses and recoveries on loans previously charged off are adjustments to the ACL. 23 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The Company made the accounting policy election to exclude accrued interest receivable from the amortized cost of loans and the estimate of the ACL. Accrued interest receivable on the Company’s loan s was $ 16.7 million and $ 12.1 million a t March 31, 2026 and December 31, 2025 , respectively, and is included in “ Accrued interest receivable ” on the accompanying consolidated balance sheets. The table below shows a summary of the activity in the ACL for the three months ended March 31, 2026 and 2025 (dollars in thousands).

For the three months ended March 31, 2025 , the $ 3.6 million reversal of credit losses on the consolidated statement of income includes a $ 3.7 million reversal of credit losses on loans and a $ 0.1 million provision for credit losses on unfunded loan commitments. The reversal of credit losses on loans for the three months ended March 31, 2026 was primarily due t o a decrease in total loans during the quarter, changes in the economic forecast and the completion of our CECL allowance model recalibration. The reversal of credit losses on loans for the three months ended March 31, 2025 was primarily due to net recoveries on one loan relationship that became impaired in the third quarter of 2021 as a result of Hurricane Ida. 24 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) The following tables outline the activity in the ACL by collateral type for the three months ended March 31, 2026 and 2025 , and show both the allowance and portfolio balances for loans individually and collectively evaluated for impairment as of March 31, 2026 and 2025 (dollars in thousands).

Modifications that do not impact the contractual payment terms, such as covenant waivers, modification of a contingent acceleration clauses, and insignificant payment delays are not included in the disclosures. When principal forgiveness is provided, the amount of forgiveness is charged-off against the ACL. Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or portion of the loan) is written off. During the three months ended March 31, 2026 and 2025 , the Company did not provide any modifications under these circumstances to borrowers experiencing financial difficulty. 25 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 6.

DERIVATIVE FINANCIAL INSTRUMENTS Customer Derivatives – Interest Rate Swaps The Company enters into interest rate swaps that allow commercial loan customers to effectively convert a variable-rate commercial loan agreement to a fixed-rate commercial loan agreement. The Company then enters into a corresponding swap agreement with a third party in order to economically hedge its exposure through the customer agreement. The interest rate swaps with both the customers and third parties are not designated as hedges under FASB ASC Topic 815 “Derivatives and Hedging,” and changes in fair value are recognized in other operating income. As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings as required by FASB ASC Topic 820 “Fair Value Measurement” (“ASC 820” ). The Company did not recognize any gains or losses in other operating income resulting from fair value adjustments of these swap agreements during the three months ended March 31, 2026 and 2025 . The table below presents the notional amounts and fair values of the Company’s derivative financial instruments as well as their classification on the accompanying consolidated balance sheets at March 31, 2026 and December 31, 2025 (dollars in thousands).

Collateral received from counterparties is included in “Interest-bearing deposits” in the accompanying consolidated balance sheets. 28 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) NOTE 9. FAIR VALUES OF FINANCIAL INSTRUMENTS In accordance with ASC 820, disclosure of fair value information about financial instruments, whether or not recognized in the balance sheet, is required. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date under current market conditions. Fair value is best determined based upon quoted market prices or exit prices. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows, and the fair value estimates may not be realized in an immediate settlement of the instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company. If there has been a significant decrease in the volume and level of activity for the asset or liability, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions. The Company holds SBIC qualified funds and other investment funds that do not have a readily determinable fair value. In accordance with ASC 820, these investments are measured at fair value using the net asset value practical expedient and are not required to be classified in the fair value hierarchy. At March 31, 2026 and December 31, 2025 , the fair values of these investments were $ 3.6 million and $ 3.5 million, respectively, and are included in “Other assets” in the accompanying consolidated balance sheets. Fair Value Hierarchy In accordance with ASC 820, the Company groups its financial assets and financial liabilities measured at fair value in three levels, based on the markets in which the assets and liabilities are traded, and the reliability of the assumptions used to determine fair value. Level 1 – Valuation is based upon quoted prices for identical assets or liabilities traded in active markets. Level 2 – Valuation is based upon observable inputs other than quoted prices included in level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data. Level 3 – Valuation is based upon unobservable inputs that are supported by little or no market activity. This includes certain pricing models, discounted cash flow methodologies, and similar techniques that use significant unobservable inputs, as well as an entity’s own assumptions that market participants would use in pricing the assets or liabilities. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Fair Value of Assets and Liabilities Measured on a Recurring Basis The following methods and assumptions were used by the Company in estimating the fair value of assets and liabilities valued on a recurring basis: AFS Investment Securities and Marketable Equity Securities – Where quoted prices are available in an active market, the Company classifies the securities within level 1 of the valuation hierarchy. Securities are defined as both long and short positions. Level 1 securities include marketable equity securities in corporate stocks and mutual funds. If quoted market prices are not available, the Company estimates fair values using pricing models and discounted cash flows that consider standard input factors such as observable market data, benchmark yields, interest rate volatilities, broker/dealer quotes, and credit spreads. Examples of such instruments, which would generally be classified within level 2 of the valuation hierarchy if observable inputs are available, include obligations of the U.S. Treasury and U.S. government agencies and corporations, obligations of state and political subdivisions, corporate bonds, residential mortgage-backed securities, and commercial mortgage-backed securities. In certain cases where there is limited activity or less transparency around inputs to the valuation, the Company classifies those securities in level 3. Management monitors the current placement of securities in the fair value hierarchy to determine whether transfers between levels may be warranted based on market reference data, which may include reported trades; bids, offers or broker/dealer quotes; benchmark yields and spreads; as well as other reference data. At March 31, 2026 and December 31, 2025 , all of the Company’s level 3 investments were obligations of state and political subdivisions. The Company estimated the fair value of these level 3 investments using discounted cash flow models, the key inputs of which are the coupon rate, current spreads to the yield curves, and expected repayment dates, adjusted for illiquidity of the local municipal market and sinking funds, if applicable. Option-adjusted models may be used for structured or callable notes, as appropriate. Derivative Financial Instruments – The fair value for interest rate swap agreements is based upon the expected future cash flows of the agreements discounted at market rates. These derivative instruments are classified in level 2 of the fair value hierarchy. 29 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Assets and liabilities measured at fair value on a recurring basis are summarized in the table below as of the dates indicated (dollars in thousands).

The following methods and assumptions were used by the Company in estimating the fair value of assets and liabilities valued on a nonrecurring basis: Loans Individually Evaluated – For collateral dependent loans where the borrower is experiencing financial difficulty, the expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral, which is based on third -party appraisals. Individually evaluated loans that are not collateral dependent are evaluated based on a discounted cash flow methodology. Credits deemed uncollectible are charged to the ACL. Since not all valuation inputs are observable, these nonrecurring fair value determinations are classified as level 3. Other Real Estate Owned – Other real estate owned consists of properties acquired through foreclosure or acceptance of a deed in lieu of foreclosure and real property no longer used in the Bank’s business operations. Other real estate owned is recorded at the lower of its net book value or fair value, and it may be necessary to record nonrecurring fair value adjustments for declines in fair value. Fair value, when recorded, is determined based on appraisals by qualified licensed appraisers and adjusted for management’s estimates of costs to sell. Accordingly, values for other real estate owned are classified as level 3. Quantitative information about assets measured at fair value on a nonrecurring basis based on significant unobservable inputs (level 3 ) is summarized below as of March 31, 2026 and December 31, 2025 . There were no liabilities measured on a nonrecurring basis at March 31, 2026 or December 31, 2025 (dollars in thousands).

( 3 ) Other real estate owned that was re-measured during the period had a carrying value of $ 2.0 million at December 31, 2025 . 32 Table of Contents INVESTAR HOLDING CORPORATION NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS (Unaudited) Financial Instruments Accounting guidance requires the disclosure of estimated fair value information about certain on- and off-balance sheet financial instruments, including those financial instruments that are not measured and reported at fair value on a recurring or nonrecurring basis. The significant methods and assumptions used by the Company to estimate the fair value of financial instruments are discussed below. Cash and Cash Equivalents – For these short-term instruments, the fair value is the carrying value. Investment Securities and Equity Securities – The fair value measurement techniques and assumptions for AFS securities and marketable equity securities is discussed earlier in the note. The same measurement techniques and assumptions were applied to the valuation of HTM securities and nonmarketable equity securities including equity in correspondent banks. Loans – The fair value of portfolio loans, net is determined using an exit price methodology. The exit price methodology is based on a discounted cash flow analysis, in which projected cash flows are based on contractual cash flows adjusted for prepayments for certain loan types (e.g. residential mortgage loans and multifamily loans) and the use of a discount rate based on expected relative risk of the cash flows. The discount rate selected considers loan type, maturity date, a liquidity premium, cost to service, and cost of capital. Deposits – The fair values disclosed for demand deposits are, by definition, equal to the amount payable on demand at the reporting date (that is, their carrying amounts). Fair values for fixed-rate certificates of deposit are estimated using a discounted cash flow analysis that applies market interest rates on comparable instruments to a schedule of aggregated expected monthly maturities on time deposits. Short-Term Borrowings – The carrying amounts of federal funds purchased, repurchase agreements, and other short-term borrowings approximate their fair values because of their short-term nature. Long-Term Borrowings, including Junior Subordinated Debt Securities – The fair values of long-term borrowings are estimated using discounted cash flow analyses based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements. Subordinated Debt Securities – The fair value of subordinated debt is estimated based on current market rates on similar debt in the market. Derivative Financial Instruments – The fair value measurement techniques and assumptions for derivative financial instruments is discussed earlier in the note. The estimated fair values of the Company’s financial instruments are summarized in the tables below as of the dates indicated (dollars in thousands).

NOTE 11. COMMITMENTS AND CONTINGENCIES Unfunded Commitments The Company is a party to financial instruments with off-balance sheet risk entered into in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit consisting of loan commitments and standby letters of credit, which are not included in the accompanying financial statements. Such financial instruments are recorded in the financial statements when they become payable. Commitments to extend credit are agreements to lend money with fixed expiration dates or termination clauses. The Company applies the same credit standards used in the lending process when extending these commitments and periodically reassesses the customer’s creditworthiness through ongoing credit reviews. Since some commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Collateral is obtained based on the Company’s assessment of the transaction. Substantially all standby letters of credit issued have expiration dates within one year. The table below shows the approximate amounts of the Company’s commitments to extend credit as of the dates presented (dollars in thousands). March 31, 2026 December 31, 2025 Loan commitments $ 462,192 $ 431,795 Standby letters of credit 4,533 5,436 The credit risk associated with these commitments is evaluated in a manner similar to the ACL on loans and is included in “Accrued taxes and other liabilities” in the accompanying consolidated balance sheets .

LEASES The Company’s primary leasing activities relate to certain real estate leases entered into in support of the Company’s branch operations. The Company’s lease agreements under which its branch locations are operated have all been designated as operating leases. The Company does not lease equipment under operating leases, nor does it have leases designated as finance leases. Lease expense for lease payments is recognized on a straight-line basis over the lease term. The Company has lease agreements with lease and non-lease components, which the Company has elected to account for separately, as the non-lease component amounts are readily determinable. Quantitative information regarding the Company’s operating leases is presented below as of and for the three months ended March 31, 2026 and 2025 (dollars in thousands).

The following discussion and analysis should be read in conjunction with our unaudited consolidated financial statements and related notes thereto included herein, and the audited consolidated financial statements for the year ended December 31, 2025 , including the notes thereto, and the related MD&A in the Annual Report. All cross-references to the “Notes” in this Form 10-Q refer to the Notes to Consolidated Financial Statements contained in Part I. Item 1. Financial Statements unless otherwise noted . The Bank commenced operations in 2006, and we completed our initial public offering in July 2014. On July 1, 2019, the Bank changed from a Louisiana state bank charter to a national bank charter, and its name changed to Investar Bank, National Association. Through the Bank, we provide full banking services, excluding trust services, tailored primarily to meet the needs of individuals, professionals, and small to medium-sized businesses. Our primary areas of operation are south Louisiana, including Baton Rouge, New Orleans, Lafayette, Lake Charles, and their surrounding areas; Texas, including Houston and its surrounding area, and, as of January 1, 2026, north Dallas and Wichita Falls and their surrounding areas; and Alabama, including York and Oxford and their surrounding areas. At March 31, 2026 , we operated 36 full service branches comprised of 20 full service branches in Louisiana, ten full service branches in Texas, and six full service branches in Alabama. Our strategy focuses on consistent, quality earnings through the optimization of our balance sheet. Our strategy includes originating and renewing high quality, primarily variable-rate, loans and allowing higher risk credit relationships to run off. We have kept duration short on our liabilities to provide flexibility to secure lower cost funding that was accretive to our net interest margin. Our strategy also includes growth through acquisitions, including whole-bank acquisitions, strategic branch acquisitions and asset acquisitions. We have completed eight whole-bank acquisitions since 2011 and regularly review acquisition opportunities. Our most recent whole bank acquisition was completed in January 2026. For additional information, see “Acquisition of WFB” below. Our principal business is lending to and accepting deposits from individuals and small to medium-sized businesses in our areas of operation. As a financial holding company operating through one reportable segment, we generate our income principally from interest on loans and, to a lesser extent, our securities investments, as well as from fees charged in connection with our various loan and deposit services. Our principal expenses are interest expense on interest-bearing customer deposits and borrowings, salaries and employee benefits, occupancy costs, data processing and other operating expenses. We measure our performance through our net interest margin, return on average assets, and return on average equity, among other metrics, while seeking to maintain appropriate regulatory leverage and risk-based capital ratios. Acquisition of WFB On July 1, 2025, we announced that we had entered into the Agreement and Plan of Merger by and between the Company and WFB, headquartered in Wichita Falls, Texas, which provided for the merger of WFB with and into the Company, with the Company as the surviving corporation, followed by the merger of FNB, WFB’s wholly-owned subsidiary, with and into the Bank, with the Bank as the surviving bank. We completed the acquisition of WFB and FNB on January 1, 2026. All of the issued and outstanding shares of WFB common stock were converted into aggregate merger consideration consisting of $7.2 million in cash and 3,955,272 shares of our common stock for an aggregate transaction value of $112.9 million. This value is based on the Company’s closing stock price on December 31, 2025 of $26.72 per common share. On January 1, 2026, we acquired $1.15 billion in total assets, $950.2 million in net loans and $1.02 billion in total deposits. For additional information, see Note 2. Business Combinations. Private Placement of Series A Preferred Stock In connection with the WFB transaction, on July 1, 2025, we completed a private placement of 32,500 shares of our newly designated Series A Preferred Stock with selected institutional and other accredited investors at a price of $1,000 per share, for aggregate gross proceeds of $32.5 million. The net proceeds were $30.4 million, after deducting placement agent fees and other offering-related expenses. The Company utilized the net proceeds from the offering to support the acquisition of WFB and for general corporate purposes, including organic growth and other potential acquisitions. 38 Table of Contents Certain Events That Affect Period-over-Period Comparability Acquisitions . As discussed above, o n January 1, 2026, we completed the acquisition of WFB. Changing Inflation and Interest Rates . During 2025, beginning in September 2025, the Federal Reserve reduced the federal funds target rate three times by 75 basis points on a cumulative basis to 3.50% to 3.75%. Accordingly, the prevailing federal funds target rate for the three months ended March 31, 2026 was lower than for the three months ended March 31, 2025. Hurricane Ida . During the first quarter of 2025, we recorded a $3.3 million recovery of loans previously charged off as a result of a property insurance settlement related to a loan relationship that became impaired in the third quarter of 2021 as a result of Hurricane Ida, and we also recorded related noninterest expense of $0.2 million. Private Placement of Series A Preferred Stock . As discussed above, o n July 1, 2025, we completed a private placement of our newly designated Series A Preferred Stock. 39 Table of Contents Overview of Financial Condition and Results of Operations Total assets increased $1.04 billion, or 36.8% , to $3.88 billion at March 31, 2026 , compared to $2.83 billion at December 31, 2025 .

As of March 31, 2026 , estimated uninsured deposits represented approximately 36% of our total deposits. ● Net interest income for the three months ended March 31, 2026 was $32.7 million, an increase of $14.3 million, or 78.0% , compared to $18.3 million for the three months ended March 31, 2025 , which was the result of an $18.8 million increase in interest income partially offset by a $4.5 million decrease in interest expense. We experienced margin expansion as our yield on interest-earning assets increased and our cost of funds decreased for the respective periods. ● During the three months ended March 31, 2026 , our net interest margin was 3.59% , compared to 2.87% for the three months ended March 31, 2025 . ● For the three months ended March 31, 2026 , we recorded a reversal of credit losses of $2.1 million compared to a reversal of credit losses of $3.6 million f or the three months ended March 31, 2025 . ● Noninterest income increased $1.0 million, or 48.2% , to $3.0 million for the three months ended March 31, 2026 , compared to $2.0 million for the three months ended March 31, 2025 . ● Noninterest expense increased $6.6 million, or 40.7%, to $22.8 million for the three months ended March 31, 2026 , compared to $16.2 million for the three months ended March 31, 2025 . ● Nonperforming loans were 0.66% of total loans at March 31, 2026 , compared to 0.43% at December 31, 2025 . ● Return on average assets increased to 1.25% for the three months ended March 31, 2026 , compared to 0.94% for the three months ended March 31, 2025 . ● Return on average common equity was 12.12% for the three months ended March 31, 2026 , compared to 10.31% for the three months ended March 31, 2025 . ● Book value per common share reached a record high of $27.97 at March 31, 2026, compared to $27.63 at December 31, 2025 . ● During the three months ended March 31, 2026 , we paid $1.5 million to repur chase 53,420 shares of common stock compared to $0.6 million to repurchase 34,992 shares of common stock during the three months ended March 31, 2025 . ● Stockholders’ equity increased $113.6 million, or 37.7%, to $414.6 million at March 31, 2026 compared to December 31, 2025 . 40 Table of Contents Discussion and Analysis of Financial Condition Loans General . Loans constitute our most significant asset, comprising 79.2% and 76.8% of our total assets at March 31, 2026 and December 31, 2025 , respectively. Total loans increased $891.8 million, or 41.0% , to $3.07 billion at March 31, 2026 , compared to $2.18 billion at December 31, 2025 . The increase in loans was primarily the result of the acquisition of WFB, which increased total loans $961.9 million on January 1, 2026. We are emphasizing the origination of high margin loans that promote long-term profitability and proactively exiting credit relationships that do not fit this strategy. Our variable-rate loans as a percentage of total loans increased to 49% at March 31, 2026 compared to 38% at December 31, 2025. Included in variable-rate loans as of March 31, 2026 are adjustable-rate mortgage loans we acquired in connection with our acquisition of WFB. The table below sets forth the balance of loans outstanding by loan type as of the dates presented, and the percentage of each loan type to total loans (dollars in thousands). March 31, 2026 December 31, 2025 Percentage of Percentage of Amount Total Loans Amount Total Loans Construction and development $ 318,868 10.4 % $ 147,980 6.8 % 1-4 Family 920,480 30.0 376,238 17.3 Multifamily 135,081 4.4 130,005 6.0 Farmland 7,803 0.3 4,788 0.2 Commercial real estate Owner-occupied (1) 505,882 16.5 460,126 21.1 Nonowner-occupied 504,784 16.4 452,142 20.8 Total mortgage loans on real estate 2,392,898 78.0 1,571,279 72.2 Commercial and industrial (1) 661,803 21.6 595,263 27.4 Consumer 13,115 0.4 9,431 0.4 Total loans $ 3,067,816 100 % $ 2,175,973 100 % (1) The Company ’ s business lending portfolio consists of loans secured by owner-occupied commercial real estate properties and commercial and industrial loans. At March 31, 2026 , the Company’s business lending portfolio, which consists of loans secured by owner-occupied commercial real estate properties and commercial and industrial loans, was $1.17 billion, an increase of $112.3 million, or 10.6% , compared to $1.06 billion at December 31, 2025 . The increase in the business lending portfolio was primarily driven by the acquisition of WFB, partially offset by loan amortization. Construction and development loans totaled $318.9 million at March 31, 2026, an increase of $170.9 million, or 115.5%, compared to $148.0 million at December 31, 2025. The increase in construction and development loans was primarily due to the acquisition of WFB. 1-4 Family loans totaled $920.5 million at March 31, 2026, an increase of $544.2 million, or 144.7%, compared to $376.2 million at December 31, 2025. The increase in 1-4 family loans was primarily due to the acquisition of WFB. Substantially all of the 1-4 family loans acquired from WFB were consumer mortgage loans with an adjustable rate. During the third quarter of 2023, we exited the consumer mortgage loan origination business to transition into shorter duration, higher risk-adjusted return asset classes in an effort to focus more on our core business and optimize profitability. Our strategy is to allow the consumer mortgage portfolio to amortize and remix the loan portfolio by replacing consumer mortgage loans with owner-occupied commercial real estate loans and commercial and industrial loans. We will continue our strategy to allow the consumer mortgage portfolio to amortize, including those loans acquired through our acquisition of WFB. The consumer mortgage portfolio was approximately $879.8 million a nd $224.5 million at March 31, 2026 and December 31, 2025, respectively. The increase was due to the acquisition of WFB. Our consumer mortgage portfolio is included in the 1-4 family and construction and development categories. At March 31, 2026 , the remaining loans in the construction and development category consisted primarily of commercial properties, and t he remaining loans in the 1-4 family category consisted primarily of second mortgages, home equity loans, home equity lines of credit, and business purpose loans secured by 1-4 family residential real estate. Nonowner-occupied loans totaled $504.8 million at March 31, 2026, an increase of $52.6 million, or 11.6%, compared to $452.1 million at December 31, 2025. The increase in nonowner-occupied loans was primarily due to the acquisition of WFB, partially offset by loan amortization and payoffs that aligned with our continued strategy to optimize and de-risk the mix of the portfolio. 41 Table of Contents Loan Concentrations . Loan concentrations are considered to exist when there are amounts loaned to multiple borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. At March 31, 2026 and December 31, 2025 , we had no concentrations of loans exceeding 10% of total loans other than loans in the categories listed in the table above. The table below sets forth the balance of owner-occupied loans by industry based on NAICS code and nonowner-occupied loans by property type as of the dates presented (dollars in thousands).

The following table reflects contractual loan maturities of loans in our loan portfolio and the amount of such loans with fixed and variable interest rates in each maturity range at March 31, 2026 (dollars in thousands). Adjustable-rate mortgage loans that we acquired in connection with our acquisition of WFB are reflected in the “Loans with variable rates ” portion of the table; however, the rate of these loans is generally fixed for an initial period depending on the loan terms. One Year or Less After One Year Through Five Years After Five Years Through Fifteen Years After Fifteen Years Total Mortgage loans on real estate: Construction and development $ 259,415 $ 49,972 $ 9,138 $ 343 $ 318,868 1-4 Family 33,026 88,927 47,504 751,023 920,480 Multifamily 26,166 90,586 5,847 12,482 135,081 Farmland 1,175 4,143 2,221 264 7,803 Commercial real estate Owner-occupied 112,802 200,850 187,991 4,239 505,882 Nonowner-occupied 191,673 199,086 111,510 2,515 504,784 Commercial and industrial 324,398 185,114 152,207 84 661,803 Consumer 3,073 8,387 1,416 239 13,115 Total loans $ 951,728 $ 827,065 $ 517,834 $ 771,189 $ 3,067,816 Loans with fixed rates: Mortgage loans on real estate: Construction and development $ 144,282 $ 18,166 $ 3,899 $ 145 $ 166,492 1-4 Family 22,284 57,831 38,967 206,037 325,119 Multifamily 20,444 44,686 3,245 840 69,215 Farmland 356 2,935 788 — 4,079 Commercial real estate Owner-occupied 19,459 136,930 171,480 1,443 329,312 Nonowner-occupied 121,227 180,071 86,488 157 387,943 Commercial and industrial 45,712 124,515 110,547 — 280,774 Consumer 2,852 8,143 1,269 81 12,345 Total loans with fixed rates $ 376,616 $ 573,277 $ 416,683 $ 208,703 $ 1,575,279 Loans with variable rates: Mortgage loans on real estate: Construction and development $ 115,134 $ 31,805 $ 5,240 $ 197 $ 152,376 1-4 Family 10,742 31,096 8,537 544,986 595,361 Multifamily 5,720 45,900 2,604 11,642 65,866 Farmland 820 1,208 1,432 264 3,724 Commercial real estate Owner-occupied 93,344 63,920 16,510 2,796 176,570 Nonowner-occupied 70,445 19,016 25,021 2,359 116,841 Commercial and industrial 278,686 60,599 41,660 84 381,029 Consumer 221 244 147 158 770 Total loans with variable rates $ 575,112 $ 253,788 $ 101,151 $ 562,486 $ 1,492,537 42 Table of Contents Investment Securities We purchase investment securities primarily to provide a source for meeting liquidity needs, with return on investment a secondary consideration. We also use investment securities as collateral for certain deposits and other types of borrowings. Investment securities represented 12% of our total assets and totaled $460.6 million at March 31, 2026, an increase of $41.8 million, or 10.0% , from $418.8 million at December 31, 2025 . The increase in investment securities at March 31, 2026 compared to December 31, 2025 was driven primarily by a $17.7 million increase in obligations of the U.S. Treasury and U.S. government agencies and corporations, a $13.7 million increase in residential mortgage-backed securities and a $9.3 million increase in commercial mortgage-backed securities . Due in large part to higher interest rates and market volatility, net unrealized losses in our AFS investment securities portfolio totaled $47.2 million at March 31, 2026, compared to $45.4 million at December 31, 2025. For additional information, see Note 4. Investment Securities. Shortly after the acquisition of WFB, substantially all of the securities from the acquired portfolio were sold at carrying value, resulting in net proceeds of approximately $50.5 million. The table below shows the carrying value of our investment securities portfolio by investment type and the percentage that such investment type comprises of our entire portfolio as of the dates indicated (dollars in thousands). March 31, 2026 December 31, 2025 Balance Percentage of Portfolio Balance Percentage of Portfolio Obligations of the U.S. Treasury and U.S. government agencies and corporations $ 36,428 7.9 % $ 18,751 4.5 % Obligations of state and political subdivisions 63,020 13.7 62,613 14.9 Corporate bonds 25,338 5.5 24,682 5.9 Residential mortgage-backed securities 262,951 57.1 249,247 59.5 Commercial mortgage-backed securities 72,864 15.8 63,520 15.2 Total $ 460,601 100 % $ 418,813 100 % The investment portfolio consists of AFS and HTM securities. We do not hold any investments classified as trading. We classify debt securities as HTM if management has the positive intent and ability to hold the securities to maturity. HTM debt securities are stated at amortized cost. Securities not classified as HTM are classified as AFS and are stated at fair value . As of March 31, 2026 , AFS securities comprised 90% of our total investment securities. Due to the nature of the investments, current market prices, and the current interest rate environment, we determined that the declines in the fair values of the AFS and HTM securities portfolio were not attributable to credit losses at March 31, 2026 and December 31, 2025 . Accordingly, no ACL was recorded related to our investment securities. The carrying values of our AFS securities are adjusted for unrealized gains or losses not attributable to credit losses as valuation allowances, and any gains or losses are reported on an after-tax basis as a component of other comprehensive income (loss). The table below sets forth the stated maturities and weighted average yields of our investment debt securities based on the amortized cost of our investment portfolio at March 31, 2026 (dollars in thousands). One Year or Less After One Year Through Five Years After Five Years Through Ten Years After Ten Years Amount Yield Amount Yield Amount Yield Amount Yield Held to maturity: Obligations of state and political subdivisions $ 23 5.26 % $ 2,192 4.09 % $ 7,255 5.88 % $ 36,728 7.11 % Residential mortgage-backed securities — — — — — — 1,846 3.15 Available for sale: Obligations of the U.S. Treasury and U.S. government agencies and corporations 5,538 4.02 5,246 5.18 24,797 4.18 1,196 4.21 Obligations of state and political subdivisions 30 3.86 4,544 2.53 5,361 2.55 8,562 3.34 Corporate bonds 994 3.62 9,077 5.37 13,405 4.35 3,000 4.17 Residential mortgage-backed securities — — 283 1.95 3,386 2.98 294,231 2.84 Commercial mortgage-backed securities 11 1.66 6,130 4.14 2,734 3.74 71,185 3.43 $ 6,596 $ 27,472 $ 56,938 $ 416,748 The maturity of mortgage-backed securities reflects scheduled repayments based upon the contractual maturities of the securities. Weighted average yields on tax-exempt securities are calculated based on amortized cost on a fully tax equivalent basis assuming a federal tax rate of 21%, when applicable. 43 Table of Contents Deposits The following table sets forth the composition of our deposits and the percentage of each deposit type to total deposits at March 31, 2026 and December 31, 2025 (dollars in thousands). March 31, 2026 December 31, 2025 Amount Percentage of Total Deposits Amount Percentage of Total Deposits Noninterest-bearing demand deposits $ 640,129 19.8 % $ 445,986 19.0 % Interest-bearing demand deposits 938,758 29.0 608,807 25.9 Money market deposits 374,842 11.6 255,500 10.9 Brokered demand deposits — — 2 — Savings deposits 164,815 5.1 136,124 5.8 Brokered time deposits 101,217 3.1 204,069 8.7 Time deposits 1,013,052 31.4 699,761 29.7 Total deposits $ 3,232,813 100 % $ 2,350,249 100 % Total deposits were $3.23 billion at March 31, 2026, an increase of $882.6 million, or 37.6%, compared to $2.35 billion at December 31, 2025 . The increase in deposits was primarily the result of the acquisition of WFB, which increased total deposits $1.02 billion on January 1, 2026, consisting of $187.9 million and $835.5 million of noninterest-bearing deposits and interest-bearing deposits, respectively. The increase in noninterest-bearing demand deposits, interest-bearing demand deposits, and money market deposits at March 31, 2026 compared to December 31, 2025 was primarily the result of the acquisition of WFB and organic growth. The increase in time deposits at March 31, 2026 compared to December 31, 2025 was primarily the result of the acquisition of WFB, partially offset by the run-off of higher yielding time deposits. Brokered time deposits decreased to $101.2 million at March 31, 2026 from $204.1 million at December 31, 2025. We utilize brokered time deposits, entirely in denominations of less than $250,000, to secure fixed cost funding and reduce short-term borrowings. At March 31, 2026, the balance of brokered time deposits remained below 10% of total assets, and the remaining weighted average duration was approximate ly five months with a weighted average rate o f 3.94%. At March 31, 2026, our estimated uninsured deposits were $1.16 billion, or approximately 36% of total deposits, compared to $793.2 million, or approximately 34% of our total deposits at December 31, 2025. The estimates are based on the same methodologies and assumptions used for our regulatory reporting requirements. The insured deposit data does not reflect an evaluation of all of the account ownership category distinctions that would determine the availability of deposit insurance to individual accounts based on FDIC regulations. The following table shows scheduled maturities of time deposits in excess of the FDIC insurance limit of $250,000 at March 31, 2026 and December 31, 2025 (dollars in thousands). March 31, 2026 December 31, 2025 Time remaining until maturity: Three months or less $ 133,360 $ 103,130 Over three months through six months 102,562 60,840 Over six months through twelve months 100,128 62,241 Over twelve months 13,591 10,320 Total $ 349,641 $ 236,531 44 Table of Contents Borrowings At March 31, 2026 , total borrowings included securities s old under agreements to repurchase, FHLB advances, subordinated debt issued in 2022, an d junior subordinated debentures assumed through acquisitions. We had $18.4 million of securities sold under agreements to repurchase at March 31, 2026 and $11.2 million at December 31, 2025 . Our advances from the FHLB were $136.0 million at March 31, 2026 , an increase of $20.0 million compared to FHLB advances of $116.0 million at December 31, 2025 . Based on original maturities, at March 31, 2026 , $36.0 million were short-term and $100.0 million were long-term FHLB advances , compared to $36.0 million short-term and $80.0 million long-term FHLB advances at December 31, 2025 . FHLB advances are used to fund new loan and investment activity that is not funded by deposits or other borrowings. The main source of our short-term borrowings are advances from the FHLB . The rate charged for advances from the FHLB is directly tied to the Federal Reserve’s federal funds target rate. As of March 31, 2026, the federal funds target rate was 3.50% to 3.75%. The average balances and cost of short-term borrowings for the three months ended March 31, 2026 and 2025 are summarized in the table below (dollars in thousands). Average Balances Cost of Short-term Borrowings Three months ended March 31, Three months ended March 31, 2026 2025 2026 2025 Short-term FHLB advances $ 36,000 $ 38,570 3.83 % 4.44 % Repurchase agreements 13,501 12,071 0.81 0.75 Total short-term borrowings $ 49,501 $ 50,641 3.01 % 3.56 % The following table sets forth certain information regarding securities sold under agreements to repurchase for the three months ended March 31, 2026 and 2025 (dollars in thousands).

The $23.0 million and $8.8 million in junior subordinated debt at March 31, 2026 and December 31, 2025 , respectively, represented the junior subordinated debentures that we assumed through acquisitions. The increase in junior subordinated debt was due to the acquisition of WFB and consisted of $9.2 million of unsecured debt obligations due to trusts and a $5.0 million loan, which matures in October 2029, related to our Southlake corporate office. On January 1, 2026, we assumed WFB’s obligations on an unsecured basis with respect to a $10.0 million note to TIB, N.A. We repaid the note in full in January 2026. For a description of the 2032 Notes , see our Annual Report, Part II. Item 7. “MD&A – Discussion and Analysis of Financial Condition – Borrowings – 2032 Notes” a nd Note 10 to the financial statements included in such report. Stockholders ’ Equity Stockholders’ equity was $414.6 million at March 31, 2026, an increase of $113.6 million compared to December 31, 2025. The increase was primarily attributable to the acquisition of WFB, $12.0 million of net income for the three months ended March 31, 2026, partially offset by $1.5 million for share repurchases, a $1.4 million increase in accumulated other comprehensive loss due to a decrease in the fair value of the Bank’s AFS securities portfolio, $1.5 million in dividends declared on common stock, and $0.5 million in dividends declared on the Series A Preferred Stock. 45 Table of Contents Results of Operations Performance Summary As of and for the three months ended March 31, 2026 2025 Net income $ 12,024 $ 6,293 Net income available to common shareholders 11,496 6,293 Diluted earnings per common share 0.77 0.63 Performance Ratios Return on average assets 1.25 % 0.94 % Return on average common equity 12.12 10.31 Book value per common share $ 27.97 $ 25.63 Net Interest Income and Net Interest Margin Net interest income, our principal source of earnings, is the difference between the interest income generated by earning assets and the total interest cost of the deposits and borrowings obtained to fund those assets. Factors affecting the level of net interest income include the volume of earning assets and interest-bearing liabilities, yields earned on loans and investments and rates paid on deposits and other borrowings, the level of nonperforming loans, the amount of noninterest-bearing liabilities supporting earning assets, and the interest rate environment. Net interest margin is the ratio of net interest income to average interest-earning assets. The primary factors affecting net interest margin are changes in interest rates, competition, and the shape of the interest rate yield curve. The Federal Reserve Board sets various benchmark rates, including the federal funds target rate, and thereby influences the general market rates of interest, including the deposit and loan rates offered by financial institutions. During 2025, beginning in September, the Federal Reserve reduced the federal funds target rate three times by 75 basis points on a cumulative basis to 3.50% to 3.75%, where it remained as of May 8, 2026. Accordingly, the prevailing federal funds target rate during the three months ended March 31, 2026 was lower than during the three months ended March 31, 2025. For additional discussion, see Certain Events That Affect Period-over-Period Comparability – Changing Inflation and Interest Rates. Three months ended March 31, 2026 vs. three months ended March 31, 2025 . Net interest income increased 78.0% to $32.7 million for the three months ended March 31, 2026 compared to $18.3 million for the same period in 2025. The increase was primarily due to a higher average balance of, and an increase in the yield on, the loan portfolio, partially offset by an increase in the average balance of interest-bearing demand deposits and time deposits. Average loans increased by $987.0 million for the three months ended March 31, 2026 primarily due to the acquisition of WFB, which, in addition to higher loan yields, resulted in a $17.4 million increase in interest income on loans compared to the same period in 2025. Average brokered time deposits were $152.3 million for the three months ended March 31, 2026 compared to $252.3 million during the three months ended March 31, 2025, which along with lower rates paid, resulted in a $1.5 million decrease in interest expense compared to the three months ended March 31, 2025. Average interest-bearing demand deposits increased by $517.9 million, which, combined with an increase in rates, resulted in a $3.6 million increase in interest expense in the first quarter of 2026 compared to the same period in 2025. A higher average balance of time deposits partially offset by a decrease in rates paid on time deposits resulted in a $2.1 million increase in interest expense compared to the same period in 2025. Average noninterest-bearing deposits increased by $203.6 million. Our yield on interest-earning assets increased primarily due to an increase in the average balance of, and the yield on, the loan portfolio. Rates paid on interest-bearing liabilities decreased primarily as a result of the overall decrease in prevailing interest rates. Interest income was $53.2 million for the three months ended March 31, 2026, compared to $34.4 million for the same period in 2025. Loan interest income made up substantially all of our interest income for the three months ended March 31, 2026 and 2025, although interest on investment securities contributed 7.7% of interest income during the first quarter of 2026 compared to 9.7% during the first quarter of 2025. The overall yield on interest-earning assets was 5.86% and 5.39% for the three months ended March 31, 2026 and 2025, respectively. The loan portfolio yielded 6.28% and 5.88% for the three months ended March 31, 2026 and 2025, respectively, while the yield on the investment portfolio was 3.44% for the three months ended March 31, 2026 compared to 3.10% for the three months ended March 31, 2025. The overall yield on interest-earning assets increased 47 basis points for the quarter ended March 31, 2026 compared to the quarter ended March 31, 2025 and was primarily driven by a 40 basis point increase in the yield on the loan portfolio and a 34 b asis point increase in the yield on the investment securities portfolio. Interest expense was $20.5 million for the three months ended March 31, 2026, an increase of $4.5 million compared to interest expense of $16.1 million for the three months ended March 31, 2025. An increase in interest expense of $5.3 million resulted from an increase in the volume of interest-bearing liabilities, primarily interest-bearing deposits and time deposits. A decrease of $0.8 million resulted from the decrease in the cost of interest-bearing liabilities, primarily time deposits and brokered time deposits. Average interest-bearing liabilities increased by $812.8 million for the three months ended March 31, 2026 compared to the same period in 2025, while average interest-bearing deposits increased by $774.9 million, primarily due to an increase in average interest-bearing demand deposits and average time deposits. We increased rates on our interest-bearing demand deposits during the first quarter of 2026 compared to the first quarter of 2025 to attract and retain lower cost deposits relative to higher cost short-term borrowings and brokered time deposits, and the interest-bearing demand deposits acquired from WFB had a higher rate than legacy interest-bearing demand deposits. Average time deposits increased due to the acquisition of WFB; however, we reduced rates on our time deposits during the first quarter of 2026 compared to the first quarter of 2025 due to lower prevailing market interest rates . The cost of deposits decreased 30 basis points to 2.85% for the three months ended March 31, 2026 compared to 3.15% for the three months ended March 31, 2025 primarily as a result of a lower average balance of, and a decrease in rates paid on, brokered time deposits and a decrease in rates paid on time deposits, partially offset by a higher average balance of time deposits and a higher average balance of, and an increase in the rates paid on, interest-bearing demand deposits. The cost of interest-bearing liabilities decreased 28 basis points to 2.94% for the three months ended March 31, 2026 compared to 3.22% for the same period in 2025. Net interest margin was 3.59% for the three months ended March 31, 2026, an increase of 72 basis points from 2.87% for the three months ended March 31, 2025. The increase in net interest margin was primarily driven by a 47 basis point increase in the yield on interest-earning assets and a 28 basis point decrease in the cost of interest-bearing liabilities . 46 Table of Contents Average Balances and Yields . The following table sets forth average balance sheet data, including all major categories of interest-earning assets and interest-bearing liabilities, together with the interest earned or paid and the average yield or rate paid on each such category for the three months ended March 31, 2026 and 2025 .

The following table illustrates the primary components of noninterest income for the three months ended March 31, 2026, compared to the three months ended March 31, 2025 (dollars in thousands). Three months ended March 31, Increase (Decrease) 2026 2025 $ % Noninterest income: Service charges on deposit accounts $ 956 $ 795 $ 161 20.3 % Loss on sale or disposition of fixed assets, net — (3 ) 3 100.0 Loss on sale of other real estate owned, net (84 ) — (84 ) — Gain on sale of loans 26 — 26 — Interchange fees 559 390 169 43.3 Income from BOLI 664 448 216 48.2 Change in the fair value of equity securities 130 (76 ) 206 271.1 Other operating income 729 457 272 59.5 Total noninterest income $ 2,980 $ 2,011 $ 969 48.2 % Three months ended March 31, 2026 vs. three months ended March 31, 2025 . Total noninterest income increased $1.0 million, or 48.2% , to $3.0 million for the three months ended March 31, 2026 compared to $2.0 million for the three months ended March 31, 2025 . The increase in noninterest income was primarily attributable to a $0.2 million increase in interchange fees, a $0.2 million increase in income from BOLI, a $0.2 million increase in service charges on deposit accounts, a $0.2 million increase in change in fair value of equity securities, and a $0.3 million increase in other operating income, partially offset by a $0.1 million increase in loss on sale of other real estate owned. The increase in other operating income was primarily attributable to a $0.1 million increase in distributions from other investments and a $0.1 million increase in wealth management income. Noninterest Expense Noninterest expense includes salaries and employee benefits and other costs associated with the conduct of our operations. Our goal is to manage our costs within the framework of our operating strategy of generating consistent, quality earnings. The following table illustrates the primary components of noninterest expense for the three months ended March 31, 2026, compared to the three months ended March 31, 2025 (dollars in thousands). Three months ended March 31, Increase (Decrease) 2026 2025 $ % Noninterest expense: Depreciation and amortization $ 1,344 $ 721 $ 623 86.4 % Salaries and employee benefits 12,947 9,603 3,344 34.8 Occupancy 988 641 347 54.1 Data processing 1,214 897 317 35.3 Marketing 99 111 (12 ) (10.8 ) Professional fees 799 591 208 35.2 Acquisition expense 1,728 159 1,569 986.8 Other operating expenses 3,720 3,515 205 5.8 Total noninterest expense $ 22,839 $ 16,238 $ 6,601 40.7 % Three months ended March 31, 2026 vs. three months ended March 31, 2025 . Total noninterest expense was $22.8 million for the three months ended March 31, 2026, an increase of $6.6 million, or 40.7%, compared to the same period in 2025. The increase was primarily driven by a $3.3 million increase in salaries and employee benefits, a $1.6 million increase in acquisition expense, a $0.6 million increase in depreciation and amortization, a $0.3 million increase in occupancy, a $0.3 million increase in data processing and a $0.2 million increase in other operating expense. The increases were primarily related to the acquisition of WFB on January 1, 2026. The increase in other operating expense was primarily attributable to a $0.2 million increase in FDIC assessments. Income Tax Expense Income tax expense for the three months ended March 31, 2026 and 2025 was $2.9 million and $1.4 million, respectively. The effective tax rate for the three months ended March 31, 2026 and 2025 was 19.4% and 18.4%, respectively. For the three months ended March 31, 2026 and 2025 , the effective tax rate differed from the statutory tax rate of 21% primarily due to tax-exempt interest income earned on certain loans and investment securities and income from BOLI. Risk Management The primary risks associated with our operations are credit, interest rate and liquidity risk. Changing inflation also presents risk. Credit, inflation and interest rate risk are discussed immediately below, while liquidity risk is discussed in this section under the heading Liquidity and Capital Resources further below. 48 Table of Contents Credit Risk and the Allowance for Credit Losses General. The risk of loss should a borrower default on a loan is inherent in any lending activity. Our portfolio and related credit risk are monitored and managed on an ongoing basis by our risk management department, the Board’s loan committee and the full Board. We utilize a ten point risk-rating system, which assigns a risk grade to each borrower based on a number of quantitative and qualitative factors associated with a loan transaction. The risk grade categorizes the loan into one of five risk categories based on information about the ability of borrowers to service the debt. The information includes, among other factors, current financial information about the borrower, historical payment experience, credit documentation, public information and current economic trends. These categories assist management in monitoring our credit quality. The risk categories, which are consistent with the definitions used in guidance promulgated by federal banking regulators, are as follows. • Pass (grades 1-6) – Loans not falling into one of the categories below are considered Pass. These loans have high credit characteristics and financial strength. The borrowers at least generate profits and cash flow that are in line with peer and industry standards and have debt service coverage ratios above loan covenants and our policy guidelines. For some of these loans, a guaranty from a financially capable party mitigates characteristics of the borrower that might otherwise result in a lower grade. • Special Mention (grade 7) – Loans classified as Special Mention possess some credit deficiencies that need to be corrected to avoid a greater risk of default in the future. For example, financial ratios relating to the borrower may have deteriorated. Often, a special mention categorization is temporary while certain factors are analyzed or matters addressed before the loan is re-categorized as either Pass or Substandard. • Substandard (grade 8) – Loans rated as Substandard are inadequately protected by the current net worth and paying capacity of the borrower or the liquidation value of any collateral. If deficiencies are not addressed, it is likely that this category of loan will result in the Bank incurring a loss. Where a borrower has been unable to adjust to industry or general economic conditions, the borrower’s loan is often categorized as substandard. • Doubtful (grade 9) – Doubtful loans are Substandard loans with one or more additional negative factors that makes full collection of amounts outstanding, either through repayment or liquidation of collateral, highly questionable and improbable. • Loss (grade 10) – Loans classified as Loss have deteriorated to such a point that it is not practicable to defer writing off the loan. For these loans, all efforts to remediate the loan’s negative characteristics have failed and the value of the collateral, if any, has severely deteriorated relative to the amount outstanding. Although some value may be recovered on such a loan, it is not significant in relation to the amount borrowed. At March 31, 2026 and December 31, 2025, there were no loans classified as Loss, while there were $24,000 and no loans, respectively, classified as Doubtful, $43.0 million and $38.1 million, respectively, of loans classified as Substandard, and $9.2 million and $9.7 million, respectively, of loans classified as Special Mention. An independent loan review is conducted annually, whether internally or externally, on at least 40% of commercial loans utilizing a risk-based approach designed to maximize the effectiveness of the review. Internal loan review is independent of the loan underwriting and approval process. In addition, credit analysts periodically review certain commercial loans to identify negative financial trends related to any one borrower, any related groups of borrowers or an industry. All loans not categorized as pass are put on an internal watch list, with quarterly reports to the Board. In addition, a written status report is maintained by our special assets division for all commercial loans categorized as Substandard or worse. We use this information in connection with our collection efforts. If our collection efforts are unsuccessful, collateral securing loans may be repossessed and sold or, for loans secured by real estate, foreclosure proceedings initiated. The collateral is sold at public auction for fair market value (based upon recent appraisals), with fees associated with the foreclosure being deducted from the sales price. The purchase price is applied to the outstanding loan balance. If the loan balance is greater than the sales proceeds, the deficient balance is charged-off. Allowance for Credit Losses . We account for the ACL in accordance with ASC 326, which uses the CECL accounting methodology. The CECL methodology requires that lifetime expected credit losses be recorded at the time the financial asset is originated or acquired and be adjusted each period through a provision for credit losses for changes in the expected lifetime credit losses . The ACL was $36.0 million and $26.3 million at March 31, 2026 and December 31, 2025 , respectively. On January 1, 2026, we recorded an $11.7 million ACL due to the acquisition of WFB. We maintain a separate ACL on unfunded loan commitments, which is included in “Accrued taxes and other liabilities” in the accompanying consolidated balance sheets. The ACL is generally increased by the provision for credit losses and decreased by charge-offs, net of recoveries. The reversal of credit losses for the three months ended March 31, 2026 was primarily due to a decrease in total loans during the quarter, changes in the economic forecast and the completion of our CECL allowance model recalibration . The reversal of credit losses for the three months ended March 31, 2025 was primarily due to net recoveries on one loan relationship that became impaired in the third quarter of 2021 as a result of Hurricane Ida. Periodically, we complete a CECL allowance model recalibration. This process, which was completed in the first quarter of 2026, includes peer group analysis, updates to our probability of default and loss-given default models, including prepayment and curtailment assumptions, and qualitative factor scorecard ranges, as needed. The changes resulting from the model recalibration reduced the ACL by approximately $3.0 million and $0.5 million during the three months ended March 31, 2026 and 2025, respectively. Refer to Note 1. Summary of Significant Accounting Policies – Allowance for Credit Losses in our Annual Report for further discussion of our ACL accounting policy. 49 Table of Contents The following table presents the allocation of the ACL by loan category and the percentage of loans in each loan category to total loans as of the dates indicated (dollars in thousands). March 31, 2026 December 31, 2025 Allowance for Credit Losses % of Loans in each Category to Total Loans Allowance for Credit Losses % of Loans in each Category to Total Loans Mortgage loans on real estate: Construction and development $ 1,355 10.4 % $ 1,327 6.8 % 1-4 Family 15,922 30.0 6,053 17.3 Multifamily 1,146 4.4 1,814 6.0 Farmland 8 0.3 6 0.2 Commercial real estate 9,045 32.9 11,388 41.9 Commercial and industrial 8,358 21.6 5,680 27.4 Consumer 151 0.4 81 0.4 Total $ 35,985 100 % $ 26,349 100 % The following table presents the amount of the ACL allocated to each loan category as a percentage of total loans as of the dates indicated.

Additions to the ACL are charged to the provision for credit losses on loans. Losses are charged to the ACL as incurred and recoveries on losses previously charged to the allowance are credited to the allowance at the time the recovery is collected. The table below reflects the activity in the ACL and key ratios for the periods indicated (dollars in thousands). Three months ended March 31, 2026 2025 Allowance at beginning of period $ 26,349 $ 26,721 ACL on PCD loans at acquisition 143 — ACL on PSL loans at acquisition 11,559 — Reversal of credit losses on loans (1) (1,802 ) (3,695 ) Net (charge-offs) recoveries (264 ) 3,409 Allowance at end of period $ 35,985 $ 26,435 Total loans - period end 3,067,816 2,106,631 Nonaccrual loans - period end 20,331 5,585 Key ratios: Allowance for credit losses to total loans - period end 1.17 % 1.25 % Allowance for credit losses to nonaccrual loans - period end 177.0 % 473.3 % Nonaccrual loans to total loans - period end 0.66 % 0.27 % (1) For the three months ended March 31, 2026, the $2.1 million reversal of credit losses on the consolidated statement of income includes a $1.8 million reversal of credit losses on loans and a $0.3 million reversal of credit losses on unfunded loan commitments. For the three months ended March 31, 2025, the $3.6 million reversal of credit losses on the consolidated statement of income includes a $3.7 million reversal of credit losses on loans and a $0.1 million provision for credit losses on unfunded loan commitments. 50 Table of Contents The ACL to total loans decreased to 1.17% at March 31, 2026 compared to 1.25% at March 31, 2025 , and the ACL to nonaccrual loans ratio decreased to 177.0% at March 31, 2026 compared to 473.3% at March 31, 2025 . The decrease in the ACL to total loans compared to March 31, 2025 was primarily due to the completion of our CECL allowance model recalibration and changes in the economic forecast. The decrease in ACL to nonaccrual loans compared to March 31, 2025 was primarily due to an increase in nonaccrual loans. Nonaccrual loans were $20.3 million, or 0.66% of total loans, at March 31, 2026 , an increase of $14.7 million compared to $5.6 million, or 0.27% of total loans, at March 31, 2025 . The increase in nonaccrual loans was primarily a ttributable to one primarily owner-occupied commercial real estate relationship totaling $6.6 million and nonperforming loans acquired from WFB totaling $3.2 million. The following table presents the allocation of net (charge-offs) recoveries by loan category for the periods indicated (dollars in thousands). Three months ended March 31, 2026 2025 Net Recoveries (Charge-offs) Average Balance Ratio of Net Charge-offs (Recoveries) to Average Loans Net Recoveries (Charge-offs) Average Balance Ratio of Net Charge-offs (Recoveries) to Average Loans Mortgage loans on real estate: Construction and development $ — $ 293,515 — % $ 1 $ 146,786 (0.00 )% 1-4 Family (59 ) 931,632 0.01 (15 ) 394,162 0.00 Multifamily — 130,166 — — 93,735 — Farmland — 8,350 — — 6,899 — Commercial real estate — 1,063,630 — 3,314 941,349 (0.35 ) Commercial and industrial (171 ) 654,943 0.03 131 515,494 (0.03 ) Consumer (34 ) 13,679 0.25 (22 ) 10,479 0.21 Total $ (264 ) $ 3,095,915 0.01 % $ 3,409 $ 2,108,904 (0.16 )% Charge-offs reflect the realization of losses in the portfolio that were recognized previously through the provision for credit losses on loans. Net charge-offs include recoveries of amounts previously charged off. For the three months ended March 31, 2026, net charge-offs were $0.3 million, or 0.01%, of the average loan balance for the period. Net charge-offs during the three months ended March 31, 2026 were primarily attributable to commercial and industrial loans . Net recoveries for the three months ended March 31, 2025 were $3.4 million , or 0.16%, of the average loan balance for the period. Net recoveries during the three months ended March 31, 2025 were primarily the result of a property insurance settlement related to a loan relationship that became impaired in the third quarter of 2021 as a result of Hurricane Ida. Management believes the ACL at March 31, 2026 is sufficient to provide adequate protection against losses in our portfolio. However, there can be no assurance that this allowance will prove to be adequate over time to cover ultimate losses in connection with our loans. This ACL may prove to be inadequate due to many factors, including those set forth in Part I. Item 1A. “Risk Factors” and “Cautionary Note Regarding Forward-Looking Statements” in the Company’s Annual Report. These factors could cause deterioration in credit quality that could lead us to increase our ACL in future periods. Our results of operations and financial condition could be materially adversely affected to the extent that the ACL is insufficient to cover such changes or events. Nonperforming Asse ts . No nperforming assets consist of nonperforming loans and other real estate owned. Nonperforming loans are those on which the accrual of interest has stopped or loans which are contractually 90 days past due and accruing. Loans are ordinarily placed on nonaccrual when a loan is specifically determined to be impaired or when principal and interest is delinquent for 90 days or more. Additionally, management may elect to continue the accrual when the estimated net available value of collateral is sufficient to cover the principal balance and accrued interest. It is our policy to discontinue the accrual of interest income on any loan for which we have reasonable doubt as to the payment of interest or principal. A loan may be returned to accrual status when all the principal and interest amounts contractually due are brought current and future principal and interest amounts contractually due are reasonably assured, which is typically evidenced by a sustained period of repayment performance by the borrower. Nonperforming loans were $20.4 million, or 0.66% of total loans, at March 31, 2026, an increase of $11.1 million compared to $9.3 million, or 0.43% of total loans, at December 31, 2025. The increase in nonperforming loans compared to December 31, 2025 was primarily a ttributable to one primarily owner-occupied commercial real estate relationship totaling $6.6 million and nonperforming loans acquired from WFB totaling $3.2 million. Loan Modifications to Borrowers Experiencing Financial Difficulty. Occasionally, we modify loans to borrowers in financial distress by providing certain concessions, such as principal forgiveness, an interest rate reduction, an other-than-insignificant payment delay, or a term extension, excluding covenant waivers and modification of contingent acceleration clauses, or a combination of such concessions. When principal forgiveness is provided, the amount of forgiveness is charged-off against the ACL . Upon the Company’s determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or portion of the loan) is written off. During the three months ended March 31, 2026 and 2025 , we did not provide any modifications under these circumstances to borrowers experiencing financial difficulty. 51 Table of Contents Other Real Estate Owned. Other real estate owned consists of properties acquired through foreclosure or acceptance of a deed in lieu of foreclosure and real property no longer used in the Bank’s business operations. Real estate acquired through foreclosure is initially recorded at fair value at the time of foreclosure, less estimated selling cost, and any related write-down is charged to the ACL. Real property no longer used in the Bank’s business operations is recorded at the lower of its net book value or fair value at the date of transfer to other real estate owned. For the three months ended March 31, 2026, additions to other real estate owned were $0.8 million, which were driven by transfers of 1-4 family loans to other real estate owned. Other real estate owned with a cost basis of $0.7 million was sold during the three months ended March 31, 2026 resulting in a loss of $0.1 million. No other real estate owned was sold during the three months ended March 31, 2025 . At March 31, 2026, approximately $4.5 million of loans secured by 1-4 family residential property were in the process of foreclosure. The table below provides details of our other real estate owned as of the dates indicated (dollars in thousands).

Three months ended March 31, 2026 2025 Balance, beginning of period $ 3,374 $ 5,218 Additions 760 951 Sales of other real estate owned (744 ) — Balance, end of period $ 3,390 $ 6,169 Swap Contracts. The Company enters into interest rate swap contracts that allow commercial loan customers to effectively convert a variable-rate commercial loan agreement to a fixed-rate commercial loan agreement. Under these agreements, the Company enters into a variable-rate loan agreement with a customer in addition to an interest rate swap agreement, which serves to effectively swap the customer’s variable-rate loan into a fixed-rate loan. The Company then enters into a corresponding swap agreement with a third party in order to economically hedge its exposure through the customer agreement. The interest rate swaps with both the customers and third parties are not designated as hedges, and changes in fair value are recognized through earnings . As the interest rate swaps are structured to offset each other, changes to the underlying benchmark interest rates considered in the valuation of these instruments do not result in an impact to earnings; however, there may be fair value adjustments related to credit quality variations between counterparties, which may impact earnings. The Company did not recognize any net impact in other income resulting from fair value adjustments during the three months ended March 31, 2026 and 2025 . At March 31, 2026 and December 31, 2025 , we had notional amo unts of $162.8 million and $180.8 million, respectively, in interest rate swap contracts with customers and $162.8 million and $180.8 million, respectively, in offsetting interest rate swap contracts with other financial institutions. At March 31, 2026 and December 31, 2025 , the fair value of the swap contracts consisted of gross assets of $11.4 million and $11.7 million, respectively, and gross liabilities of $11.4 million and $11.7 million, respectively, record ed in “Other assets” and “Accrued taxes and other liabilities,” respectively, in the accompanying consolidated balance sheets. For additional information, see Note 8. Derivative Financial Instruments. Impact of Inflation . The inflationary outlook in the U.S. remains uncertain. Inflation has moderated in recent periods; however, it has remained higher than the Federal Reserve’s target inflation rate of two percent. A decrease in the general level of interest rates may lead to, among other things, prepayments on our loan and mortgage-backed securities portfolios as borrowers refinance their loans at lower rates, lower rates on new loans, lower rates on existing variable rate loans and lower yields on investment securities, which may be offset by lower costs of interest-bearing liabilities. If interest-earning assets mature or reprice more quickly, or to a greater degree than interest-bearing liabilities, falling interest rates could reduce net interest income. Significant fluctuations in interest rates makes our business and balance sheet more challenging to manage. For additional information, see Interest Rate Risk below, and Item 1A. “Risk Factors – Risks Related to our Business – Changes in interest rates could have an adverse effect on our profitability” and “– Inflation and rising prices may continue to adversely affect our results of operations and financial condition” in our Annual Report. 52 Table of Contents Interest Rate Risk Market risk is the risk of loss from adverse changes in market prices and rates. Since the majority of our assets and liabilities are monetary in nature, our market risk arises primarily from interest rate risk inherent in our lending and deposit activities. A sudden and substantial change in interest rates may adversely impact our earnings and profitability because the interest rates borne by assets and liabilities do not change at the same speed, to the same extent, or on the same basis. Accordingly, our ability to proactively structure the volume and mix of our assets and liabilities to address anticipated changes in interest rates, as well as to react quickly to such fluctuations, can significantly impact our financial results. To that end, management actively monitors and manages our interest rate risk exposure. The ALCO has been authorized by the Board to implement our asset/liability management policy, which establishes guidelines with respect to our exposure to interest rate fluctuations, liquidity, loan limits as a percentage of funding sources, exposure to correspondent banks and brokers and reliance on non-core deposits. The goal of the policy is to enable us to maximize our interest income and maintain our net interest margin without exposing the Bank to excessive interest rate risk, credit risk and liquidity risk. Within that framework, the ALCO monitors our interest rate sensitivity and makes decisions relating to our asset/liability composition. Net interest income simulation is the Bank’s primary tool for benchmarking near term earnings exposure. Given the ALCO’s objective to understand the potential risk and volatility embedded within the current mix of assets and liabilities, standard rate scenario simulations assume total assets remain static (i.e., no growth). The Bank may also use a standard gap report in its interest rate risk management process. The primary use for the gap report is to provide supporting detailed information to the ALCO’s discussion. The Bank has particular concerns with the utility of the gap report as a risk management tool because of difficulties in relating gap directly to changes in net interest income. Hence, the income simulation is the key indicator for earnings-at-risk since it expressly measures what the gap report attempts to estimate. Short term interest rate risk management tactics are decided by the ALCO where risk exposures exist out into the one to two-year horizon. Tactics are formulated and presented to the ALCO for discussion, modification, and/or approval. Such tactics may include asset and liability acquisitions of appropriate maturities in the cash market, loan and deposit product/pricing strategy modification, and derivatives hedging activities to the extent such activity is authorized by the Board. Since the impact of rate changes due to mismatched balance sheet positions in the short-term can quickly and materially affect the current year’s income statement, they require constant monitoring and management. Within the gap position that management directs, we attempt to structure our assets and liabilities to minimize the risk of either a rising or falling interest rate environment. We manage our gap position for time horizons of one month, two months, three months, four to six months, seven to twelve months, 13-24 months, 25-36 months, 37-60 months and more than 60 months. The goal of our asset/liability management is for the Bank to maintain a net interest income at risk in an up or down 100 basis point environment at less than (5)%. At March 31, 2026 , the Bank was within the policy guidelines for asset/liability management. 53 Table of Contents The table below de picts the estimated impact on net interest income of immediate changes in interest rates at the specified levels. As of March 31, 2026 Changes in Interest Rates (in basis points) Estimated Increase/Decrease in Net Interest Income (1) +300 (0.3)% +200 (0.3)% +100 —% -100 0.5% -200 0.9% -300 1.0% (1) The percentage change in this column represents the projected net interest income for 12 months on a flat balance sheet in a stable interest rate environment versus the projected net interest income in the various rate scenarios. The computation of the prospective effects of hypothetical interest rate changes requires numerous assumptions regarding characteristics of new business and the behavior of existing positions. These business assumptions are based upon our experience, business plans and published industry experience. Key assumptions include asset prepayment speeds, competitive factors, the relative price sensitivity of certain assets and liabilities, and the expected life of non-maturity deposits. However, there are a number of factors that influence the effect of interest rate fluctuations on us that are difficult to measure and predict. For example, a rapid drop in interest rates might cause our loans to be repaid at a more rapid pace and certain mortgage-related investments to prepay more quickly than projected. This could mitigate some of the benefits of falling rates as are expected when we are in a negatively-gapped position. Conversely, a rapid rise in rates could give us an opportunity to increase our margins and stifle the rate of repayment on our mortgage-related loans, which would increase our returns; however, we may need to increase the rates we offer to maintain or increase deposits, which would adversely impact our margins. As a result, because these assumptions are inherently uncertain, actual results will differ from simulated results. Liquidity and Capital Resources Liquidity. Liquidity is a measure of the ability to fund loan commitments and meet deposit maturities and withdrawals in a timely and cost-effective way. Our primary sources of funds are from deposits, amortization of loans, loan prepayments and the maturities of loans, payments and maturities of investment securities and other investments and other cash flows provided from operations. Uses of funds include deposits, debt service, lease commitments, unfunded commitments, and dividends. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit outflows, loan prepayments, and borrowings are greatly influenced by general interest rates, economic conditions, and the competitive environment in which we operate. To minimize funding risks, we closely monitor our liquidity position through periodic reviews of maturity profiles, yield and rate behaviors, and loan and deposit forecasts. Excess short-term liquidity is usually invested in overnight federal funds sold. Our core deposits, which are deposits excluding brokered demand deposits, brokered time deposits, and time deposits greater than $250,000 are our most stable source of liquidity to meet our cash flow needs due to the nature of the long-term relationships generally established with our customers. Maintaining the ability to acquire these funds as needed in a variety of markets, and within ALCO compliance targets, is essential to ensuring our liquidity. At March 31, 2026 and December 31, 2025 , 66% and 68%, respectively, of our total assets were funded by core deposits. Our investment portfolio is another alternative for meeting our cash flow requirements. Investment securities generate cash flow through interest payments, principal payments and maturities, and they generally have readily available markets that allow for their conversion to cash. At March 31, 2026, 90% of our investment securities portfolio was classified as AFS, and we had gross unrealized losses in our AFS investment securities portfolio of $47.9 million and gross unrealized gains of $0.7 million. The sale of securities in a loss position would cause us to record a loss on sale of investment securities in noninterest income in the period during which the securities were sold. Some securities are pledged to secure certain deposit types or short-term borrowings, such as FHLB advances, which impacts their liquidity. At March 31, 2026, securities with a carrying value of $134.8 million were pledged to secure certain deposits, borrowings, and other liabilities, compared to $75.6 million i n pledged securities at December 31, 2025. Other sources available for meeting liquidity needs include advances from the FHLB, repurchase agreements and other borrowings. FHLB advances may be used to meet day to day liquidity needs, particularly if the prevailing interest rate on an FHLB advance compares favorably to the rates that we would be required to pay to attract deposits. At March 31, 2026 , the balanc e of our outstanding advances with the FHLB was $136.0 million, consisting of $36.0 million short-term and $100.0 million long-term advances based on original maturities , an increase of $20.0 million, compared to $116.0 million, consisting of $36.0 million short-term and $80.0 million long-term advances based on original maturities, at December 31, 2025. The total amount of remaining credit available to us from the FHLB at March 31, 2026 was $619.6 million . At March 31, 2026 , our FHLB borrowings were collateralized by a blanket pledge of certain loans totaling approximately $927.6 million . Repurchase agreements are contracts for the sale of securities which we own with a corresponding agreement to repurchase those securities at an agreed upon price and date. Our policies limit the use of repurchase agreements to those collateralized by investment securities. We had $18.4 milli on of repurchase agreements outstanding at March 31, 2026 and $11.2 million at December 31, 2025. 54 Table of Contents We maintain unsecured lines of credit with First National Bankers Bank and The Independent Bankers Bank totaling $60.0 million. These lines of credit are federal funds lines of credit and are used for overnight borrowing only. The lines of credit mature at various times within the next year. There were no outstanding balances on our unsecured lines of credit at March 31, 2026 and December 31, 2025. At March 31, 2026 , we held $79.6 million of cash and cash equivalents and maintained approximate l y $619.6 million of available funding from FHLB advances and maintained $60.0 million in unsecured lines of credit with correspondent banks. Cash and cash equivalents and available funding represent 65% of uninsured deposits of $1.16 billion at March 31, 2026 . We maintain an effective shelf registration statement with the SEC, which can be utilized to meet liquidity needs. The shelf registration statement allows us to raise capital of up to $150 million from time to time through the sale of debt securities, common stock, preferred stock, depositary shares, warrants, subscription rights and units, or a combination thereof, subject to market conditions. In addition, at March 31, 2026 and December 31, 2025, we had $17.0 million in aggregate principal amount of subordinated debt outstanding, consisting entirely of our 2032 Notes. For additional information on our 2032 Notes, see our Annual Report, Part II. Item 7. “MD&A – Discussion and Analysis of Financial Condition – Borrowings” and Note 10 to the financial statements included in such report. Our liquidity strategy is focused on using the least costly funds available to us in the context of our balance sheet composition and interest rate risk position. Accordingly, we target growth of noninterest-bearing deposits. Although we cannot directly control the types of deposit instruments our customers choose, we can influence those choices with the interest rates and deposit specials we offer. In recent periods, the proportion of our deposits represented by noninterest-bearing deposits has declined primarily due to rising market interest rates as customers have migrated to higher yielding alternatives. At March 31, 2026, we held $101.2 million of brokered time deposits and no brokered demand deposits as defined for federal regulatory purposes. At December 31, 2025, we held $204.1 million of brokered time deposits and de minimis brokered demand deposits as defined for federal regulatory purposes. We utilize brokered time deposits to secure fixed cost funding and reduce short-term borrowings. We utilize brokered demand deposits when pricing is more favorable than other short-term borrowings. We hold QwickRate® deposits, included in our time deposit balances, which we obtain through a qualified network, to address liquidity needs when rates on such deposits compare favorably with deposit rates in our markets. We held $11.3 million of QwickRate® deposits at March 31, 2026 and December 31, 2025. The following table presents, by type, our funding sources, which consist of total average deposits and borrowed funds, as a percentage of total funds and the total cost of each funding source for the three months ended March 31, 2026 and 2025.

Our primary sources of capital include retained earnings, capital obtained through acquisitions and proceeds from the sale of our capital stock and subordinated debt. We may issue capital stock and debt securities from time to time to fund acquisitions and support our organic growth. As noted elsewhere in this report, on July 1, 2025 we completed a private placement of Series A Preferred Stock. We used the net proceeds from the offering to support the acquisition of WFB and for general corporate purposes, including organic growth and other potential acquisitions. During the three months ended March 31, 2026 and 2025, we paid $1.1 m illion and $1.0 million in dividends on our common stock, respectively. We declared dividends on our common stock of $0.11 per share during the three months ended March 31, 2026 compared to dividends of $0.105 per share during the three months ended March 31, 2025. During the three months ended March 31, 2026, we paid $0.5 m illion in dividends on our Series A Preferred Stock compared to none during the three months ended March 31, 2025. We declared dividends on our Series A Preferred Stock of $16.25 per share during the three months ended March 31, 2026 compared to none during the three months ended March 31, 2025. Our Board has authorized a share repurchase program, and at March 31, 2026, we had 327,976 shar es of our common stock remaining authorized for repurchase under the program. During the three months ended March 31, 2026, we paid $1.5 million to repurchas e 53,420 s hares of our common stock, compared to paying $0.6 million to repurchas e 34,992 s hares of our common stock during the three months ended March 31, 2025 . The aggregate purchase price does not include the effect of excise tax incurred on net share repurchases. 55 Table of Contents We are subject to various regulatory capital requirements administered by the Federal Reserve and the OCC which specify capital tiers, including the following classifications for the Bank under the OCC’s prompt corrective action regulations. Capital Tiers (1) Tier 1 Leverage Ratio Common Equity Tier 1 Capital Ratio Tier 1 Capital Ratio Total Capital Ratio Ratio of Tangible to Total Assets Well capitalized 5% or above 6.5% or above 8% or above 10% or above Adequately capitalized 4% or above 4.5% or above 6% or above 8% or above Undercapitalized Less than 4% Less than 4.5% Less than 6% Less than 8% Significantly undercapitalized Less than 3% Less than 3% Less than 4% Less than 6% Critically undercapitalized 2% or less (1) In order to be well capitalized or adequately capitalized, a bank must satisfy each of the required ratios in the table. In order to be undercapitalized or significantly undercapitalized, a bank would need to fall below just one of the relevant ratio thresholds in the table. In order to be well capitalized, the Bank cannot be subject to any written agreement or order requiring it to maintain a specific level of capital for any capital measure. Pursuant to regulatory capital rules, the Company has made an election not to include unrealized gains and losses in the investment securities portfolio for purposes of calculating “Tier 1” capital and “Tier 2” capital. The Company and the Bank each were in compliance with all regulatory capital requirements at March 31, 2026 and December 31, 2025 . The Bank also was considered “well-capitalized” under the OCC’s prompt corrective action regulations as of these dates. The following table presents the actual capital amounts and regulatory capital ratios for the Company and the Bank as of the dates presented (dollars in thousands).

The Bank enters into loan commitments and standby letters of credit in the normal course of its business. Loan commitments are made to meet the financing needs of our customers, while standby letters of credit commit the Bank to make payments on behalf of customers when certain specified future events occur. The credit risks associated with loan commitments and standby letters of credit are essentially the same as those involved in making loans to our customers. Accordingly, our normal credit policies apply to these arrangements. Collateral (e.g., securities, receivables, inventory, equipment, etc.) is obtained based on management’s credit assessment of the customer. The credit risk associated with these commitments is evaluated in a manner similar to the ACL. The ACL on unfunded loan commitments is included in “Accrued taxes and other liabilities” in the accompanying consolidated balance sheets and was $0.3 million and $0.4 million at March 31, 2026 and December 31, 2025, respectively. Loan commitments and standby letters of credit do not necessarily represent future cash requirements, in that while the customer typically has the ability to draw upon these commitments at any time, these commitments often expire without being drawn upon in full or at all. Substantially all of our standby letters of credit expire within one year. Our unfunded loan commitments and standby letters of credit outstanding are summarized below as of the dates indicated (dollars in thousands): March 31, 2026 December 31, 2025 Loan commitments $ 462,192 $ 431,795 Standby letters of credit 4,533 5,436 The Company closely monitors the amount of remaining future commitments to borrowers in light of prevailing economic conditions and adjusts these commitments as necessary. The Company intends to continue this process as new commitments are entered into or existing commitments are renewed. Additionally, at March 31, 2026, the Company had unfunded commitments of $1.4 million for its investment in SBIC qualified funds and other investment funds. For the three months ended March 31, 2026 and for the year ended December 31, 2025, except as disclosed herein and in the Company’s Annual Report, we engaged in no off-balance sheet transactions that we believe are reasonably likely to have a material effect on our financial condition, results of operations, or cash flows. Lease Obligations The Company’s primary leasing activities relate to certain real estate leases entered into in support of the Company’s branch operations. The Company’s branch locations operated under lease agreements have all been designated as operating leases. The Company does not lease equipment under operating leases, nor does it have leases designated as finance leases. The following table presents, as of March 31, 2026, contractually obligated lease payments due under non-cancelable operating leases by payment date (dollars in thousands). Less than one year $ 686 One to three years 1,318 Three to five years 968 Over five years 71 Total $ 3,043 57 Table of Contents Critical Accounting Estimates The preparation of our consolidated financial statements in accordance with GAAP requires us to make estimates and judgments that affect our reported amounts of assets, liabilities, income and expenses and related disclosure of contingent assets and liabilities. Although independent third parties are often engaged to assist us in the estimation process, management evaluates the results, challenges and assumptions used and considers other factors which could impact these estimates. Actual results may differ from these estimates under different assumptions or conditions. There were no material changes or developments during the reporting period with respect to methodologies that the Company uses when applying what management believes are significant accounting policies and developing critical accounting estimates, which are those estimates made in accordance with GAAP that involve a significant level of estimation uncertainty and have had or are reasonably likely to have a material impact on our financial condition or results of operations. We believe that the judgments, estimates and assumptions that we use in the preparation of our consolidated financial statements are appropriate. For more detailed information about our accounting policies, please refer to Note 1. Summary of Significant Accounting Policies of our Annual Report.
