We also have audited the Company’s internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three-year period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework: (2013) issued by COSO. Basis for Opinion The Company’s management is responsible for these financial statements, for maintaining effective internal control over financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Report. Our responsibility is to express an opinion on the Company’s financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects. Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures include examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions. Definitions and Limitations of Internal Control Over Financial Reporting A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of reliable financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded 72 Table of Contents as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions or that the degree of compliance with the policies or procedures may deteriorate. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing separate opinions on the critical audit matter or on the accounts or disclosures to which it relates. Allowance for Credit Losses on Loans – Qualitative Factor Adjustments As described in Note 4 to the financial statements the Company’s allowance for credit losses on loans (“ACL-Loans”) was $44.4 million as of December 31, 2025. To estimate the ACL – Loans the Company segments the loan portfolio into loan pools based on loan type and similar credit risk elements. Loans with similar risk characteristics are evaluated in pools and the Company utilizes a discounted cash flow (“DCF”) method where probability of default and loss given default assumptions are applied to a projective model of the pool’s cash flows while considering prepayment and principal curtailment effects. The Company utilizes peer call report data to measure historical credit loss experience with similar risk characteristics within the segments over an economic cycle and has incorporated macroeconomic drivers to adjust the historical loss experience estimate for reasonable and supportable forecasts that are quantitatively related to the Company’s historical credit loss experience. The expected credit losses for each loan pool are then adjusted for changes in qualitative factors not inherently considered in the quantitative analyses and include lending policy, changes in nature and volume of loans, staff experience, changes in volume and trends of problem loans, concentration risk, trends in underlying collateral values, external factors, quality of loan review system and other economic conditions. We identified the qualitative factor adjustments included in the ACL-Loans as a critical audit matter. The principal considerations for our determination included the high degree of judgment and subjectivity in auditing management’s identification and measurement of qualitative factor adjustments. This required a high degree of effort, specialized skills and knowledge, and significant judgment. The primary procedures we performed to address this critical audit matter included: ● Evaluated the design and operating effectiveness of controls relating to the ACL-Loans, including: o Controls over the completeness and accuracy of data included in the model used to determine the ACL-Loans, and o Controls over management’s review and approval of the ACL-Loans, including management’s estimation of the qualitative factor adjustments applied within the qualitative framework. ● Evaluated the reasonableness of management’s qualitative factor adjustments, including testing management’s identification of qualitative factors, the application of qualitative factor adjustments within the model, and assessing the completeness and accuracy of data utilized in development of the qualitative adjustments. 73 Table of Contents ● Evaluated management’s judgments and assumptions related to the qualitative adjustments by assessing relevant trends in credit quality and evaluating the relationship of the trends to the qualitative adjustments applied to the ACL-Loans . ​ /s/ Forvis Mazars, LLP We have served as the Company’s auditor since 2019.

Organization The Company provides a variety of financial services to individual and business customers, primarily located in Wisconsin, through the Bank. The Bank is subject to competition from other traditional and nontraditional financial institutions and is also subject to the regulations of certain federal agencies and undergoes periodic examinations by those regulatory authorities including the Office of the Comptroller of the Currency and the Federal Reserve Bank. Use of Estimates in Preparation of Financial Statements The preparation of the accompanying consolidated financial statements in conformity with GAAP in the United States requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. Actual results may differ from these estimates. The allowance for credit losses, carrying value of real estate owned, carrying value of goodwill, fair value of mortgage servicing rights, and fair values of financial instruments are inherently subjective and are susceptible to significant change. Business Combinations The Company accounts for business combinations under the acquisition method of accounting in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 805, Business Combinations. The Company recognizes the full fair value of the assets acquired and liabilities assumed and immediately expenses transaction costs. If the amount of consideration exceeds the fair value of assets purchased less the fair value of liabilities assumed, goodwill is recorded. Alternatively, if the amount by which the fair value of assets purchased exceeds the fair value of liabilities assumed and consideration paid, a gain (bargain purchase gain) is recorded. Fair values are subject to refinement for up to one year after the closing date of an acquisition as information relative to closing date fair values becomes available. Results of operations of the acquired business are included in the statement of income from the effective date of the acquisition. Additional information regarding acquisitions is provided in Note 2. Cash and Cash Equivalents For purposes of reporting cash flows in the consolidated financial statements, cash and cash equivalents include cash on hand, interest-bearing and noninterest-bearing accounts in other financial institutions, and federal funds sold, all of which have original maturities of three months or less. Generally, federal funds are purchased and sold for one day periods. In the normal course of business, the Company maintains cash and due from bank balances with correspondent banks. Accounts at each institution that are insured by the Federal Deposit Insurance Corporation have up to $250,000 of insurance. Total uninsured balances held at December 31, 2025 and 2024 were approximately $ 5.5 million and $ 1.6 million, respectively. ​ 81 Table of Contents Securities Securities are classified as held to maturity (“HTM”) or available for sale (“AFS”) at the time of purchase. Investment securities classified as HTM, which management has the intent and ability to hold to maturity, are reported at amortized cost. Investment securities classified as AFS, which management has the intent and ability to hold for an indefinite period of time, but not necessarily to maturity, are carried at fair value, with unrealized gains and losses, net of related deferred income taxes, included in stockholders’ equity as a separate component of other comprehensive income. The net carrying value of debt securities classified as HTM or AFS is adjusted for amortization of premiums and accretion of discounts utilizing the effective interest method over the expected estimated maturity. Such amortization and accretion is included as an adjustment to interest income from securities. Interest and dividends are included in interest income from securities. Transfers of debt securities into the HTM classification from the AFS classification are made at fair value as of the date of transfer. The unrealized holding gain or loss as of the date of transfer is retained in other comprehensive income and in the carrying value of the HTM securities, establishing the amortized cost of the security. These unrealized holding gains and losses as of the date of transfer are amortized or accreted over the remaining life of the security. Realized gains or losses, determined on the basis of the cost of specific securities sold, are included in earnings. The Bank evaluates securities for potential credit losses at least on a quarterly basis, and more frequently when economic or market concerns warrant such evaluation. For AFS securities, management determines whether the decline in fair value below the amortized cost basis (impairment) is due to credit-related or other factors. In making that evaluation, management considers the extent to which the fair value has been less than cost, the financial condition and near-term prospects of the issuer, and the intent and ability of the Company to hold the security for a period of time sufficient to allow for any anticipated recovery in fair value. Any impairment on AFS securities that is related to factors other than credit is recognized in other comprehensive income, net of related deferred income taxes. Credit-related impairment on AFS securities is recognized as an allowance for credit losses (“ACL”) on the balance sheet based on the amount by which the amortized cost basis exceeds the fair value, with a corresponding charge to net income. Both the ACL and charge to net income may be reversed if conditions change. However, if the Company intends to sell, or more likely than not will be required to sell, an impaired AFS security before recovering its amortized cost basis, the entire impairment must be recognized in net income with a corresponding adjustment to the security’s amortized cost basis rather than through the establishment of an ACL. For HTM securities, management determines whether an ACL is necessary after considering the facts and circumstances of the underlying investment securities and evaluates expected credit losses by security type, aggregated by similar risk characteristics, based on historical credit losses adjusted for current conditions and supportable forecasts. The Company’s HTM portfolio primarily consists of U.S. Treasury securities which have an explicit government guarantee; therefore, no ACL has been recorded for these securities. Other Investments Other investments are carried at cost, minus impairment if any, or, where available, recently observable market prices, which approximates fair value, and consist of FHLB stock, FRB stock, Bankers’ Bancorporation stock, and public and private company securities. Other investments are evaluated for impairment at least on an annual basis. Loans Held for Sale Loans originated and intended for sale in the secondary market, consisting of the current origination of certain fixed-rate mortgage loans, are carried at the lower of cost or estimated fair value in the aggregate. A gain or loss is recognized at the time of the sale reflecting the present value of the difference between the contractual interest rate of the loans sold and the yield to the investor, adjusted for the initial value of mortgage servicing rights associated with loans sold with servicing retained. Net unrealized losses, if any, are recorded as a valuation allowance and charged to earnings. Loans and Related Interest Income - Originated Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoffs are carried at their amortized cost basis, which is the unpaid principal balance outstanding, net of deferred loan fees and costs and any direct principal charge-offs. 82 Table of Contents Interest income is accrued on the unpaid principal balance using the simple interest method. The accrual of interest income on loans is discontinued when, in the opinion of management, there is reasonable doubt as to the borrower’s ability to meet payment of interest or principal when due. Loans are generally placed on nonaccrual status when contractually past due 90 days or more as to interest or principal, though they may be placed in such status earlier. Loans past due 90 days or more may continue on accrual only when they are well secured and/or in process of collection or renewal. When interest accrual is discontinued, all previously accrued but uncollected interest is reversed against current period interest income. Except in very limited circumstances, cash collections on nonaccrual loans are credited to the loan receivable balance and no interest income is recognized on those loans until the principal balance is paid in full. Accrual of interest may be resumed when the customer is current on all principal and interest payments and has been paying on a timely basis for a sustained period of time. A description of each segment of the loan portfolio, including the corresponding credit risk, is included below: Commercial / Industrial – Commercial and industrial loans are typically made to small and middle-market established businesses involved in professional services, accommodation and food services, health care, financial services, wholesale trade, manufacturing, distribution, retailing and non-profits. Most clients are privately owned with markets that range from local to national in scope. Many of the loans to this segment are secured by liens on corporate assets and the personal guarantees of the principals. The regional economic strength or weakness impacts the relative risks in this loan category. There is little concentration in any one business sector, and loan risks are generally diversified among many borrowers. Risks associated with commercial and industrial loans include monitoring the condition of the collateral which often consists of inventory, accounts receivable, and other non-real estate assets. Declines in general economic conditions and other events can cause cash flows to fall to levels insufficient to service this debt. Commercial Real Estate – Owner Occupied and Non-owner Occupied – Commercial real estate loans generally have terms of 10 years or less, although payments may be structured on a longer amortization basis. We evaluate each borrower on an individual basis and attempt to determine their business risks and credit profile. We attempt to reduce credit risk in the commercial real estate portfolio by emphasizing loans on owner-occupied industrial, office, and retail buildings where the loan-to-value ratio, established by independent appraisals, does not generally exceed 85 % of cost or appraised value. We also generally require that a borrower’s cash flow exceed 110 % of monthly debt service obligations. In order to ensure secondary sources of payment and liquidity to support a loan request, we typically review all of the personal financial statements of the principal owners and require their personal guaranties. Commercial real estate loans are generally viewed as having more risk of default than residential real estate loans. They are also typically larger than residential real estate loans and consumer loans and depend on cash flows from the owner’s business or the property to service the debt. Because our loan portfolio contains a number of commercial real estate loans with relatively large balances, the deterioration of one or a few of these loans could cause a significant increase in our levels of nonperforming assets. Non-owner occupied commercial real estate also carries an elevated risk of vacancy inhibiting cash flow and creating an inability to service the debt. Multi-Family – Multi-family loans are a subset of commercial real estate loans and generally carry similar terms and underwriting requirements. These loans are broken out as a separate segment due to unique risk characteristics that they exhibit. While similar in nature to other non-owner occupied commercial real estate, they are significantly impacted by the individual credit capacity of many more individual tenants than other commercial real estate as well as the condition and capacity of the local residential housing markets. The underlying real estate also has a lack of suitable alternative uses. Construction and Development – Construction and development loans are generally limited to a term of 9 to 24 months, although payments may be structured on a longer amortization basis. Most loans will mature and require payment in full upon completion and either the sale of the property or refinance into a permanent loan. We believe that construction and development loans generally carry a higher degree of risk than long-term financing of stabilized, rented, and owner-occupied properties because repayment depends on the ultimate completion of the project and usually on the subsequent sale of the property. We attempt to reduce risk associated with construction and development loans by obtaining personal guaranties and by keeping the maximum loan-to-value ratio at or below 85 % of the lesser of cost or appraised value, depending on the 83 Table of Contents project type. Generally, we do not have interest reserves built into loan commitments but require periodic cash payments for interest from the borrower’s cash flow. Residential 1-4 Family – We offer fixed and adjustable rate residential real estate loans with terms of up to 30 years. We also offer a variety of lot loan options to consumers to purchase the lot on which they intend build their home. We also offer traditional home equity loans and lines of credit. Our underwriting criteria for, and the risks associated with, home equity loans and lines of credit are generally the same as those for first mortgage loans. Home equity loans typically have terms of 20 years or less. We generally limit the extension of credit to 90 % of the available equity of each property. These loans carry risk associated with local employment and declining real estate values. Consumer – Consumer loans are underwritten based on the borrower’s income, current debt level, past credit history, and the availability and value of collateral. Consumer rates are both fixed and variable, with negotiable terms. Our installment loans typically amortize over periods up to seven years . Although we typically require monthly principal and interest payments on our loan products, we will offer consumer loans at interest only with a single maturity date when a specific source of repayment is available. Consumer loans are generally considered to have greater risk than first or second mortgages on real estate because they may be unsecured, or, if they are secured, the value of the collateral may be difficult to assess and more likely to decrease in value than real estate. Other – We make loans utilized to purchase or carry securities as well as loans to nonprofit organizations. Other loans also include overdrawn depository accounts. Loans and Related Interest Income - Acquired Loans purchased in acquisition transactions are acquired loans, and are recorded at their fair value at the acquisition date. Acquired loans that have evidence of more-than-insignificant deterioration in credit quality since origination are considered purchased credit deteriorated (“PCD”) loans. At acquisition, an estimate of expected credit losses is made for PCD loans. This initial allowance for credit losses is allocated to individual PCD loans and added to the purchase price or acquisition date fair value to establish the initial cost basis of the PCD loans. Any difference between the unpaid principal balance of PCD loans and the amortized cost basis is considered to relate to noncredit factors, resulting in a discount or premium that is accreted or amortized to interest income. For acquired loans not deemed PCD loans at acquisition, the difference between the initial fair value mark and the unpaid principal balance is recognized in interest income over the estimated life of the loans. In addition, an initial allowance for expected credit losses is estimated and recorded as provision expense at the acquisition date. The subsequent measurement of expected credit losses for all acquired loans is the same as the subsequent measurement of expected credit losses for originated loans. Allowance for Credit Losses - Loans The ACL – Loans represents management’s estimate of expected credit losses in the Company’s loan portfolio at the balance sheet date. The Company estimates the ACL – Loans based on the amortized cost basis of the underlying loan and has made an accounting policy election to exclude accrued interest from the loan’s amortized cost basis and the related measurement of the ACL – Loans. Estimating the amount of the ACL – Loans is a function of a number of factors, including but not limited to changes in the loan portfolio, net charge-offs, trends in past due and nonaccrual loans, the level of potential problem loans, and expected future economic conditions, all of which may be susceptible to significant change. We establish the ACL – Loans through charges to earnings, which are shown in the statements of income as the provision for credit losses. Specifically identifiable and quantifiable known losses are promptly charged off against the allowance. The Company uses a current expected loss model (“CECL”) to evaluate the reasonable value of the ACL - Loans. This methodology to estimate credit losses over the expected life of each loan considers historical loss rates and other qualitative adjustments, as well as a forward-looking component that considers reasonable and supportable forecasts. To develop the ACL – Loans estimate under CECL, the Company segments the loan portfolio into loan pools based on loan type and similar credit risk elements; calculates the historical loss rates for the segmented loan pools; applies the loss rates over the calculated life of the pooled loans; adjusts the forecasted macro-level economic conditions; and determines qualitative adjustments based on factors and conditions unique to the Company’s portfolio. The Company further individually evaluates PCD loans and other loans that no longer share similar risk characteristics with the collectively evaluated pools based on 84 Table of Contents the amount and timing of estimated future cash flows or collateral values and establishes specific reserves when these estimated future cash flows or collateral values do not justify the carrying value of the loan. Management believes that the ACL - Loans is adequate. While management uses available information to recognize losses on loans, future additions to the allowance may be necessary based on changes in economic conditions. In addition, various regulatory agencies, as an integral part of their examination process, periodically review the ACL - Loans. Such agencies may require the Bank to recognize additions to the allowance based on their judgments of information available to them at the time of their examination. Allowance for Credit Losses – Unfunded Commitments In addition to the ACL – Loans, the Company has established an allowance for unfunded commitments, included in other liabilities on the consolidated balance sheets, representing expected credit losses over the contractual period for which the Company is exposed to credit risk resulting from a contractual obligation to extend credit. The ACL – Unfunded Commitments is maintained at a level that management believes is sufficient to absorb losses arising from unfunded loan commitments, and is determined quarterly based on methodology similar to the methodology for determining the ACL – Loans. Premises and Equipment Premises and equipment are stated at cost less accumulated depreciation computed on the straight-line method over the estimated useful lives of the assets. Premises and equipment acquired in corporate acquisitions are recorded at estimated fair value on the date of acquisition. Maintenance and repair costs are charged to expense as incurred. Gains or losses on disposition of premises and equipment are reflected in income. Premises and equipment, and other long-term assets, are reviewed for impairment when events indicate their carrying amount may not be recoverable from future undiscounted cash flows. If impaired, the assets are recorded at fair value. Depreciation expense is computed using the straight-line method over the following estimated useful lives. ​ ​ ​ ​ Buildings and improvements ​ ​ ​ 40 years Land improvements 20 years Furniture, fixtures and equipment 2 - 7 years ​ Other Real Estate Owned Assets acquired through, or in lieu of, loan foreclosure as well as buildings that the Company no longer utilizes in its operations are held for sale and are initially recorded at fair value at the date of foreclosure or abandonment less estimated costs to sell the asset, establishing a new cost basis. Any write downs at the time of foreclosure are charged to the allowance for credit loss. OREO properties acquired in conjunction with corporate acquisitions are recorded at fair value on the date of acquisition. Subsequent to foreclosure, valuations are periodically performed by management, and a valuation allowance is established if fair value declines below carrying value. Costs relating to the development and improvement of the property are capitalized. Revenue and expenses from operations and changes in the valuation allowance are included in other expenses. Company Owned Life Insurance The Company has purchased life insurance policies on certain key executives, and also holds life insurance that was previously purchased by institutions that were subsequently acquired by the Company. Company owned life insurance is recorded at the amount that can be realized under the insurance contract at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Company owned life insurance is included in other assets. ​ Intangible Assets and Goodwill Intangible assets consist of the value of core deposits, mortgage servicing assets and the excess of purchase price over fair value of net assets (goodwill). See Note 2 for additional information on an acquisition completed in 2023. The value of core deposits are typically recorded in connection with a whole bank or branch acquisition. The value of the core deposit intangible represents the estimated value of the long-term deposit relationships acquired in the transaction. 85 Table of Contents Determining the value of core deposits and their average lives involves multiple assumptions and estimates and is typically determined by performing a discounted cash flow analysis, which involves a combination of any or all of the following assumptions: customer attrition/runoff, alternative funding costs, deposit servicing costs, and discount rates. The value of core deposits are stated at cost less accumulated amortization and are amortized on a sum of the year’s digits basis over a period of one to ten years . Mortgage servicing rights are recognized as separate assets when rights are acquired through purchase or through sale of mortgage loans with servicing retained. Servicing rights acquired through sale of financial assets are recorded based on the fair value of the servicing right. The determination of fair value is based on a valuation model and includes stratifying the mortgage servicing rights by predominant characteristics, such as interest rates and terms, and estimating the fair value of each stratum based on the present value of estimated future net servicing income. The valuation model incorporates assumptions that market participants would use in estimating future net servicing income, such as costs to service, a discount rate, and prepayment speeds. Changes in fair value are recorded as an adjustment to earnings. The Company performs an assessment of goodwill to determine whether further impairment testing of indefinite-lived intangible assets is necessary on at least an annual basis. If it is determined, as a result of performing an impairment assessment over goodwill, that it is more likely than not that goodwill is impaired, management will perform an impairment test to determine if the carrying value of goodwill is realizable. The Company evaluated goodwill and core deposit intangibles for impairment during 2025, 2024 and 2023, determining that there was no goodwill or core deposit intangible impairment. Income Taxes The Company files one consolidated federal income tax return, a state tax return in its home state of Wisconsin, and other returns in states where the Company deems its business activity necessitates filing. Federal income tax expense is allocated to each subsidiary based on an intercompany tax sharing agreement. Deferred tax assets and liabilities have been determined using the liability method. Deferred tax assets and liabilities are determined based on the difference between the financial statement and tax bases of assets and liabilities and the current enacted tax rates which will be in effect when these differences are expected to reverse. Provision (benefit) for deferred taxes is the result of changes in the deferred tax assets and liabilities. Treasury Stock Common stock shares repurchased by the Company are recorded as treasury stock at cost. Securities Sold Under Repurchase Agreements The Company sells securities under repurchase agreements. These transactions are accounted for as collateralized financing transactions and are recorded at the amounts at which the securities were sold. The Company may have to provide additional collateral to the counterparty, as necessary. Off-Balance-Sheet Financial Instruments In the ordinary course of business, the Company has entered into off-balance-sheet financial instruments including commitments to extend credit, unfunded commitments under lines of credit, and letters of credit. Such financial instruments are recorded in the consolidated financial statements when they are funded. Advertising Advertising costs are generally expensed as incurred. Earnings Per Share Computations Basic earnings per share is net income divided by the weighted average number of common shares outstanding during the period. All outstanding unvested share-based payment awards that contain rights to nonforfeitable dividends are considered participating securities for this calculation. Diluted earnings per common share includes the dilutive effect of additional potential common shares issuable under stock options ( none for the years ended December 31, 2025, 2024, or 2023). 86 Table of Contents Loss Contingencies Loss contingencies, including claims and legal actions arising in the ordinary course of business, are recorded as liabilities when the likelihood of loss is probable and an amount or range of loss can be reasonably estimated. Management does not believe that there are any such matters that will have a material effect on the consolidated financial statements at December 31, 2025 and 2024. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been relinquished. Control over transferred assets is deemed to be surrendered when the assets have been isolated from the Bank, the transferee obtains the right, free of conditions that constrain it from taking advantage of that right, to pledge or exchange the transferred assets and the Bank does not maintain effective control over the transferred assets through an agreement to repurchase them before maturity. Comprehensive Income GAAP normally requires that recognized revenues, expenses, gains and losses be included in net income. In addition to net income, another component of comprehensive income includes the after-tax effect of changes in unrealized gains and losses on available for sale securities. This item is reported as a separate component of stockholders’ equity. The Company presents comprehensive income in the statement of comprehensive income. Stock-based Compensation The Company uses the fair value method of recognizing expense for stock-based compensation based on the fair value of restricted stock awards at the date of grant as prescribed by accounting standards codification Topic 781-10 Compensation/Stock Compensation. Rate Lock Commitments Commitments to fund mortgage loans, at a set interest rate, (interest rate locks) to be sold into the secondary market and forward commitments for the future delivery of these mortgage loans are accounted for as free-standing derivatives. Fair values of these mortgage derivatives are estimated based on changes in mortgage interest rates from the date the interest rate on the loan is locked. The Bank enters into forward commitments for the future delivery of mortgage loans when interest rate locks are entered into in order to hedge the change in interest rates resulting from its commitments to fund loans. The forward commitments for the future delivery of mortgage loans are based on the Bank’s “best efforts” and therefore the Bank is not penalized if a loan is not delivered to the investor if the loan did not get originated. The fair values of the Company’s rate lock commitments to customers as of December 31, 2025 and 2024 were not material and have not been recorded. Operating Segments While the Company’s chief decision-makers monitor the revenue streams of the various products and services, operations are managed, and financial performance is evaluated on a Company-wide basis. Operating segments are aggregated into one as operating results for all segments are similar. Accordingly, all of the financial service operations are considered by management to be aggregated in one reportable operating segment. ​ Reclassifications Certain 2024 and 2023 amounts have been reclassified to conform to the presentation used in 2025. These reclassifications had no effect on the operations, financial condition or cash flows of the Company. Recently Implemented Accounting Standards In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This ASU is intended to improve the transparency and decision usefulness of income tax disclosures by requiring specific categories in the rate reconciliation table and disaggregation of taxes paid by jurisdiction. All public entities must also provide additional information for reconciling items that meet a specific quantitative threshold. This update was effective for annual periods beginning after December 15, 2024. Adoption of this update led to increased disclosure in Note 16 – Income Taxes, but did not cause any change in the accounting for operational results. ​ 87 Table of Contents New Accounting Pronouncements That Have Not Yet Been Adopted In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements. This ASU modifies the disclosure or presentation requirements of a variety of topics in the Codification. The amendments in this ASU are expected to clarify or improve disclosure and presentation requirements for certain codification topics. The effective date for each amendment will be the date on which the Security and Exchange Commission’s removal of that related disclosure from Regulation S-X or Regulation S-K becomes effective, with early adoption prohibited. If, by June 30, 2027, the Securities and Exchange Commission has not removed the applicable requirement from Regulation S-X or Regulation S-K, the pending content of the related amendment will be removed from the Codification and will not become effective for any entity. The Company does not anticipate a significant impact to its financial statement disclosures as a result of this ASU. ​ In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Topic 220): Disaggregation of Income Statement Expenses . This ASU is intended to improve the disclosures about a public entity’s income statement expense categories and addresses requests from investors and other decision makers for additional, more detailed information about income statement expense categories. The amendment applies to all public entities that are required to report income statement categories in accordance with Topic 280. The effective date for this update was amended by ASU 2025-01, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date, and is now effective for annual periods beginning after December 15, 2026, and interim reporting periods within annual reporting periods beginning after December 15, 2027. The Company anticipates that this standard may impact the level of detail in disclosures of expense categories, but will not cause any change in the accounting for operational results. In November 2025, the FASB issued ASU 2025-08, Financial Instruments – Credit Losses (Topic 326): Purchased Loans. This ASU expands the population of acquired financial assets subject to the gross-up approach contained within Topic 326. In accordance with this update, loans (excluding credit cards) acquired without credit deterioration and deemed “seasoned” are classified as purchased seasoned loans (“PSL”s) and accounted for using the gross-up approach at acquisition. All non-PCD loans (excluding credit cards) that are acquired in a business combination are deemed to be PSLs. This update is effective for annual reporting periods beginning after December 15, 2026, and interim reporting periods within those annual periods, with early adoption permitted. The Company intends to adopt this update early, and anticipates that it will have a significant impact on the accounting of its acquisition of Centre 1 Bancorp, Inc. (“Centre”) which closed on January 1, 2026. Non-PCD loans acquired as part of that transaction classified as PSL will be accounted for utilizing the gross-up approach. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270) – Narrow Scope Improvements. This ASU is intended to better clarify interim disclosure requirements and the applicability of Topic 270 by improving the navigability of the required interim disclosures and clarifying what guidance is applicable. The amendments also provide additional guidance on what disclosures would be provided in interim reporting periods. This update is effective for annual periods beginning after December 15, 2027, with early adoption permitted. The Company anticipates that this standard may impact the specific disclosures it utilizes in interim reports, but will not cause any change in the accounting for operational results. Note 2 Acquisition Hometown Bancorp, Ltd. On February 10, 2023, the Company completed a merger with Hometown Bancorp, Ltd. (“Hometown”), a bank holding company headquartered in Fond du Lac, Wisconsin, pursuant to the Agreement and Plan of Bank Merger (“Merger Agreement”), dated as of July 25, 2022 by and among the Company and Hometown, whereby Hometown merged with and into the Company, and Hometown Bank, Hometown’s wholly-owned banking subsidiary, merged with and into the Bank. Hometown’s principal activity was the ownership and operation of Hometown Bank, a state-chartered banking institution that operated ten (10) branches in Wisconsin at the time of closing. The merger consideration totaled approximately $ 130.5 million. Pursuant to the terms of the Merger Agreement, Hometown shareholders could elect to receive either 0.3962 shares of the Company’s common stock or $ 29.16 in cash for each outstanding share of Hometown common stock, subject to a maximum of 30 % cash consideration in total, with cash paid in lieu of any remaining fractional share. Company stock issued totaled 1,450,272 shares valued at approximately $ 115.1 million, with cash of $ 15.4 million comprising the remainder of merger consideration. 88 Table of Contents The fair value of the assets acquired and liabilities assumed on February 10, 2023 was as follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As Recorded by ​ ​ ​ Fair Value ​ As Recorded by ​ ​ Hometown ​ ​ ​ Adjustments ​ ​ ​ the Company Cash, cash equivalents and securities ​ $ 174,582 ​ $ ( 1,010 ) ​ $ 173,572 Other investments ​ 1,195 ​ — ​ ​ 1,195 Loans, net ​ 406,168 ​ ( 10,367 ) ​ ​ 395,801 Premises and equipment, net ​ 7,577 ​ ( 1,109 ) ​ ​ 6,468 Core deposit intangible ​ 405 ​ 16,085 ​ ​ 16,490 Other assets ​ 28,011 ​ ( 6,432 ) ​ ​ 21,579 Total assets acquired ​ $ 617,938 ​ $ ( 2,833 ) ​ $ 615,105 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Deposits ​ $ 532,165 ​ $ 209 ​ $ 532,374 Other borrowings ​ 5,000 ​ ( 331 ) ​ 4,669 Junior subordinated debentures ​ ​ 12,372 ​ ​ ( 1,464 ) ​ ​ 10,908 Other liabilities ​ 469 ​ 1,144 ​ 1,613 Total liabilities assumed ​ $ 550,006 ​ $ ( 442 ) ​ $ 549,564 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Excess of assets acquired over liabilities assumed ​ $ 67,932 ​ $ ( 2,391 ) ​ $ 65,541 Less: purchase price ​ ​ ​ ​ ​ 130,452 Goodwill ​ ​ ​ ​ ​ ​ ​ ​ 64,911 Refinement to fair value estimates (1) ​ ​ ​ ​ ​ ​ ​ ​ ( 30 ) Goodwill (after refinement) ​ ​ ​ ​ ​ $ 64,881 (1) Refinement consists of adjustments to the initial fair value estimates of other assets and liabilities. Goodwill of $ 64.9 million arising from the merger consisted largely of synergies and the cost saves resulting from the combining of operations of the companies, and is not expected to be deductible for income tax purposes. ​ The Company purchased loans through this merger for which there was, at the date of acquisition, more than insignificant deterioration of credit quality since origination.

This is based on the Company’s analysis of the risk characteristics, including credit ratings, and other qualitative factors related to these securities. The issuers of these securities continue to make timely principal and interest payments under the contractual terms of the securities. As of December 31, 2025, the Company did not intend to sell these securities and it was more likely than not that the Company would not be required to sell the debt securities before recovery of their amortized cost, which may be at maturity. The unrealized losses have occurred as a result of changes in interest rates, market spreads and market conditions subsequent to purchase, not credit deterioration. Furthermore, the Company monitors the credit quality of debt securities held to maturity quarterly through the use of credit ratings. U.S. Treasury securities at December 31, 2025 were all rated AAA and have the full faith and credit backing of the United States Government. Obligations of states and political subdivisions in an unrealized loss position at December 31, 2025 are not material to the financial statements. 91 Table of Contents Contractual maturities will differ from expected maturities for mortgage-backed securities because borrowers may have the right to call or prepay obligations without penalties.

Loans with similar risk characteristics are evaluated in pools and the Company utilizes a discounted cash flow (“DCF”) method to estimate ACL for all loan pools. Under the DCF method, probability of default (“PD”) and loss given default (“LGD”) are applied to a projective model of the pool’s cash flows while considering prepayment and principal curtailment effects. The analysis produces expected cash flows for each instrument in the pool by pairing loan-level term information (maturity date, payment amount, interest rate, etc.) with top-down pool assumptions (default rates and prepayment speeds). Management has determined that peer loss experience provides the best basis for its assessment of expected credit losses to determine the ACL. The Company utilized peer call report data to measure historical credit loss experience with similar risk characteristics within the segments over an economic cycle. Management reviewed the historical loss information to appropriately adjust for differences in current asset specific risk characteristics. ​ The historical loss experience estimate by pool is then adjusted by forecast factors that are quantitatively related to the Company’s historical credit loss experience. For all loan pools, the Company utilizes and forecasts the national unemployment rate as a loss driver. The Company also utilizes and forecasts national GDP growth as a second loss driver for its commercial real estate – owner occupied and construction and development pools, the CRE (SA) interest rates and price index as a second loss driver for its commercial real estate – non-owner occupied pool, and the S&P Case-Schiller US home price index as a second loss driver for its residential 1-4 family pool. The real retail and food services sales index was used as a second loss driver for its consumer loan pool through 2024, but was replaced by the GDP forecast for 2025 due to the GDP forecast being a more reliably forecastable driver and because our loss driver study indicated changes to GDP had a higher correlation to historic losses in this pool. This change did not have a material impact on the ACL. For both national unemployment and national GDP growth the Company utilized a twelve-month forecast period, followed by a twelve-month reversion to the mean. The Company utilized the high-end range of the Federal Reserve Bank Open Market Committee forecast for national unemployment and the low-end range for national GDP growth at December 31, 2025. As of December 31, 2025, the Company anticipates the national unemployment rate to remain consistent during the forecast period and the national GDP growth rate to rise slightly. The Company utilized long-term averages for the remaining loss drivers. The reasonable and supportable period and reversion period are re-evaluated each quarter by the Company and are dependent on the current economic environment among other factors. ​ As noted above, the Company performed its annual loss driver refresh study to determine whether the utilized loss drivers remained appropriate and also performed its annual study analyzing assumptions around prepayments, curtailments and funding within the model during 2025. While the fundamental methodology remained unchanged, these annual studies along with improved economic forecasts throughout 2025 served to marginally reduce the risk of loss projected within the model. ​ The expected credit losses for each loan pool are then adjusted for changes in qualitative factors not inherently considered in the quantitative analyses. The qualitative adjustments either increase or decrease the quantitative model estimation. The Company considers factors that are relevant within the qualitative framework which include the following (including respective weighting): lending policy ( 10 % of factor), changes in nature and volume of loans ( 10 % of factor), staff experience ( 5 % of factor), changes in volume and trends of problem loans ( 10 % of factor), concentration risk ( 10 % of factor), trends in underlying collateral values ( 10 % of factor), external factors (i.e. competition, legal and regulatory requirements; 20 % of factor), quality of loan review system ( 5 % of factor) and changes in economic conditions ( 20 % of factor). Changes in external factors, primarily the overall easing of the regulatory environment, led to management reducing the associated risk related to this component during 2025. All other qualitative factors remained consistent throughout the year. ​ Expected credit losses for loans that no longer share similar risk characteristics with the collectively evaluated pools are excluded from the collective evaluation and estimated on an individual basis. Specific allocations of the ACL for credit losses on individually evaluated loans are estimated on one of several methods, including the estimated fair value of the underlying collateral, observable market value of similar debt or the present value of expected cash flows. ​ 93 Table of Contents A summary of the activity in ACL - Loans by loan type as of December 31, 2025 is as follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ ​ ​ Commercial ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate - ​ Real Estate  - ​ ​ ​ ​ Construction ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial / ​ Owner ​ Non - Owner ​ Multi- ​ and ​ Residential ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Industrial ​ Occupied ​ Occupied ​ Family ​ Development ​ 1-4 Family ​ Consumer ​ Other ​ Total ACL - Loans - January 1, 2025 ​ $ 6,737 ​ $ 9,334 ​ $ 5,213 ​ $ 3,739 ​ $ 5,223 ​ $ 12,684 ​ $ 1,084 ​ $ 137 ​ $ 44,151 Charge-offs ​ ( 243 ) ​ ​ ( 802 ) ​ ​ — ​ ​ — ​ — ​ ( 1 ) ​ ( 42 ) ​ ( 57 ) ​ ( 1,145 ) Recoveries ​ 29 ​ ​ 31 ​ ​ — ​ ​ — ​ — ​ 77 ​ 18 ​ ​ 13 ​ 168 Provision ​ 741 ​ ​ 1,128 ​ ​ ( 632 ) ​ ​ 349 ​ ( 1,409 ) ​ 884 ​ 14 ​ 125 ​ 1,200 ACL - Loans - December 31, 2025 ​ $ 7,264 ​ $ 9,691 ​ $ 4,581 ​ $ 4,088 ​ $ 3,814 ​ $ 13,644 ​ $ 1,074 ​ $ 218 ​ $ 44,374 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ A summary of the activity in ACL - Loans by loan type as of December 31, 2024 is as follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial ​ ​ ​ Commercial ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Real Estate - ​ Real Estate - ​ ​ ​ ​ Construction ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Commercial / ​ Owner ​ Non - Owner ​ Multi- ​ and ​ Residential ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Industrial ​ Occupied ​ Occupied ​ Family ​ Development ​ 1-4 Family ​ Consumer ​ Other ​ Total ACL - Loans - January 1, 2024 ​ $ 8,471 ​ $ 9,537 ​ $ 6,055 ​ $ 4,755 ​ $ 3,581 ​ $ 10,522 ​ $ 615 ​ $ 73 ​ $ 43,609 Charge-offs ​ ( 26 ) ​ ​ ( 294 ) ​ ​ — ​ ​ — ​ — ​ ( 44 ) ​ ( 110 ) ​ ( 92 ) ​ ( 566 ) Recoveries ​ 24 ​ ​ 909 ​ ​ — ​ ​ — ​ — ​ 13 ​ 37 ​ 25 ​ 1,008 Provision ​ ( 1,732 ) ​ ​ ( 818 ) ​ ​ ( 842 ) ​ ​ ( 1,016 ) ​ 1,642 ​ 2,193 ​ 542 ​ 131 ​ 100 ACL - Loans - December 31, 2024 ​ $ 6,737 ​ $ 9,334 ​ $ 5,213 ​ $ 3,739 ​ $ 5,223 ​ $ 12,684 ​ $ 1,084 ​ $ 137 ​ $ 44,151 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ In addition to the ACL-Loans, the Company has established an ACL-Unfunded Commitments, classified in other liabilities on the consolidated balance sheets. This allowance is maintained to absorb losses arising from unfunded loan commitments related to fixed and variable rate commitments to extend credit, and is determined quarterly based on methodology similar to the methodology for determining the ACL-Loans. This quarterly assessment includes consideration of the likelihood that funding of these commitments will eventually occur. The Company has identified the unfunded portion of certain lines of credit, credit card arrangements and letters of credit as unconditionally cancellable credit exposures, meaning the Company can cancel the unfunded commitment at any time. No credit loss estimate is recorded for off-balance sheet credit exposures that are unconditionally cancelable by the Company or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement. The ACL - Unfunded Commitments was $ 3.0 million and $ 2.9 million at December 31, 2025 and 2024, respectively. See Note 20 for further information on commitments. ​ The provision for credit losses is determined by the Company as the amount to be added to the ACL loss accounts for various types of financial instruments including loans, investment securities, and off-balance sheet credit exposures after net charge-offs have been deducted to bring the ACL to a level that, in management’s judgment, is necessary to absorb expected credit losses over the lives of the respective financial instruments. ​ The following table presents the components of the provision for credit losses (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ December 31, 2025 ​ December 31, 2024 ​ December 31, 2023 Provision for credit losses on: ​ ​ ​ ​ ​ ​ ​ ​ Loans $ 1,200 ​ $ 100 ​ $ 4,292 Unfunded Commitments ​ 50 ​ ​ ( 900 ) ​ ​ 390 Total provision for credit losses $ 1,250 ​ $ ( 800 ) ​ $ 4,682 ​ 94 Table of Contents ​ A summary of past due loans as of December 31, 2025 are as follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 90 Days ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-Accrual ​ ​ 30-89 Days ​ or more ​ ​ ​ ​ ​ ​ ​ with no ​ ​ Past Due ​ Past Due ​ Non- ​ ​ ​ ​ related ​ ​ Accruing ​ and Accruing ​ Accrual ​ Total ​ allowance Commercial/industrial ​ $ 894 ​ $ — ​ $ 1,754 ​ $ 2,648 ​ $ 137 Commercial real estate - owner occupied ​ 337 ​ 2,791 ​ 2,330 ​ 5,458 ​ — Commercial real estate - non-owner occupied ​ 974 ​ — ​ — ​ 974 ​ — Multi-family ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Construction and development ​ 719 ​ 1 ​ — ​ 720 ​ — Residential 1 ‑ 4 family ​ 3,198 ​ 425 ​ 1,643 ​ 5,266 ​ 1,642 Consumer ​ 277 ​ 25 ​ 79 ​ 381 ​ 79 Other ​ — ​ — ​ — ​ — ​ — ​ ​ $ 6,399 ​ $ 3,242 ​ $ 5,806 ​ $ 15,447 ​ $ 1,858 ​ A summary of past due loans as of December 31, 2024 are as follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 90 Days ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Non-Accrual ​ ​ 30-89 Days ​ or more ​ ​ ​ ​ ​ ​ ​ with no ​ ​ Past Due ​ Past Due ​ Non- ​ ​ ​ ​ related ​ ​ Accruing ​ and Accruing ​ Accrual ​ Total ​ allowance Commercial/industrial ​ $ 50 ​ $ 328 ​ $ 2,268 ​ $ 2,646 ​ $ 1 Commercial real estate - owner occupied ​ 446 ​ — ​ 3,525 ​ 3,971 ​ 800 Commercial real estate - non-owner occupied ​ — ​ — ​ 493 ​ 493 ​ 493 Multi-family ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ — Construction and development ​ 90 ​ — ​ — ​ 90 ​ — Residential 1 ‑ 4 family ​ 1,317 ​ 1,294 ​ 511 ​ 3,122 ​ 511 Consumer ​ 108 ​ 48 ​ 29 ​ 185 ​ 29 Other ​ — ​ — ​ — ​ — ​ — ​ ​ $ 2,011 ​ $ 1,670 ​ $ 6,826 ​ $ 10,507 ​ $ 1,834 ​ A loan is considered to be collateral dependent when, based upon management’s assessment, the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. For collateral dependent loans, expected credit losses are based on the estimated fair value of the collateral at the balance sheet date, with consideration for estimated selling costs if satisfaction of the loan depends on the sale of the collateral. The following tables present collateral dependent loans by portfolio segment and collateral type, including those loans with and without a related allowance allocation (dollar amounts in thousands). A significant portion of the loan balances in these tables and essentially all of the allowance allocations relate to PCD loans which were acquired from Hometown.

All other types of relationships (ex: most residential, consumer, other) are assigned a “Pass” rating, unless they have fallen 90 days past due or more, at which time they receive a rating of 7. The Company uses split ratings for government guaranties on loans. The portion of a loan that is supported by a government guaranty is included with other Pass credits. ​ The determination of a commercial loan risk rating begins with completion of a matrix, which assigns scores based on the strength of the borrower’s debt service coverage, collateral coverage, balance sheet leverage, industry outlook, and customer concentration. A weighted average is taken of these individual scores to arrive at the overall rating. This rating is subject to adjustment by the loan officer based on facts and circumstances pertaining to the borrower. Risk ratings are subject to independent review. Commercial borrowers with ratings between 1 and 5 are considered Pass credits, with 1 being most acceptable and 5 being just above the minimum level of acceptance. Commercial borrowers rated 6 have potential weaknesses which may jeopardize repayment ability. Borrowers rated 7 have a well-defined weakness or weaknesses such as the inability to demonstrate significant cash flow for debt service based on analysis of the company’s financial information. These loans remain on accrual status provided full collection of principal and interest is reasonably expected. Otherwise they are deemed impaired and placed on nonaccrual status. Borrowers rated 8 are the same as 7 rated credits with one exception: collection or liquidation in full is not probable. 96 Table of Contents The following tables present total loans by risk ratings and year of origination.

Loans to officers, directors, and shareholders owning 10% or more of the Company, that we are aware of, were made on the same terms, including interest rates and collateral, as those prevailing at the time for comparable transactions with others and did not involve more than the normal risk of collectability or present other unfavorable features. Such transactions were entered into in the ordinary course of business and in compliance with applicable laws and regulations governing insider transactions. ​ A summary of loans to directors, executive officers, principal shareholders, and their affiliates for the years ended December 31 is as follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​ ​ 2024 Balances at beginning ​ $ 62,851 ​ $ 63,892 Net increase from change in composition of officers and directors ​ ​ — ​ ​ 19,047 New loans and advances ​ 155,290 ​ 56,330 Repayments ​ ( 127,891 ) ​ ( 76,418 ) Balance at end ​ $ 90,250 ​ $ 62,851 ​ Deposits from directors, executive officers, principal shareholders, and their affiliates totaled approximately $ 20.9 million and $ 22.5 million as of December 31, 2025 and 2024, respectively. ​ See Note 9 for additional information regarding transactions with related parties. ​ Note 6 Mortgage Servicing Rights Loans serviced for others are not included in the accompanying consolidated balance sheets. MSRs are recognized as separate assets when loans sold in the secondary market are sold with servicing retained. The Company utilizes a third-party consulting firm to assist in determining an accurate assessment of the mortgage servicing rights fair value. The third-party firm collects relevant data points from numerous sources. Some of these data points relate directly to the pricing level or relative value of the mortgage servicing while other data points relate to the assumptions used to derive fair value. In addition, the valuation evaluates specific collateral types, and current and historical performance of the collateral in question. The valuation process focuses on the non-distressed secondary servicing market, common industry practices and current regulatory standards. The primary determinants of the fair value of mortgage servicing rights are servicing fee percentage, ancillary income, expected loan life or prepayment speeds, discount rates, costs to service, delinquency rates, foreclosure losses and recourse obligations. The valuation data also contains interest rate shock analyses for monitoring fair value changes in differing interest rate environments. Following is an analysis of activity in servicing rights assets that are measured at fair value (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended ​ ​ ​ Year Ended ​ ​ December 31, 2025 ​ December 31, 2024 Fair value at beginning of period ​ $ 13,369 ​ $ 13,668 ​ ​ ​ ​ ​ ​ ​ Servicing asset additions ​ 1,954 ​ 1,343 Loan payments and payoffs ​ ( 2,071 ) ​ ( 1,735 ) Changes in valuation inputs and assumptions used in the valuation model ​ 398 ​ 93 Amount recognized through earnings ​ ​ 281 ​ ​ ( 299 ) Fair value at end of period ​ $ 13,650 ​ $ 13,369 ​ ​ ​ ​ ​ ​ ​ Unpaid principal balance of loans serviced for others ​ $ 1,202,991 ​ $ 1,172,311 Mortgage servicing rights as a percent of loans serviced for others ​ 1.13 ​ 1.14 ​ During the years ended December 31, 2025 and 2024, the Company utilized economic assumptions in measuring the initial value of MSRs for loans sold whereby servicing is retained by the Company. The economic assumptions used at December 31, 2025 and 2024 included constant prepayment speed of 8.5 and 8.2 months and a discount rate of 10.17 % and 10.18 %, 99 Table of Contents respectively. The constant prepayment speeds are obtained from publicly available sources for each of the Federal National Mortgage Association and Federal Home Loan Mortgage Corporation loan programs that the Company originates under. The assumptions used by the Company are hypothetical and supported by a third-party valuation. The Company’s methodology for estimating the fair value of MSRs is highly sensitive to changes in assumptions. The carrying value of the mortgage servicing rights approximates fair market value at December 31, 2025 and 2024. ​ Note 7 Premises and Equipment An analysis of premises and equipment at December 31 follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​ ​ 2024 Land and land improvements ​ $ 12,116 ​ $ 11,082 Buildings and building improvements ​ 74,623 ​ 66,096 Furniture and equipment ​ 7,457 ​ 6,904 Totals ​ 94,196 ​ 84,082 Less accumulated depreciation ​ 16,565 ​ 14,559 Right-of-use lease asset (see Note 21) ​ ​ 1,586 ​ ​ 1,585 Premises and equipment, net ​ $ 79,217 ​ $ 71,108 ​ Included in buildings and improvements at December 31, 2025 and 2024, is $ 1.1 million and $ 0.8 million, respectively, in construction in progress.

Wisconsin did not produce guidelines for application of this new legislation until late in the first quarter of 2024. The Company’s 2023 Wisconsin tax obligation was estimated utilizing the best understanding of what the final guidelines would stipulate. When the final guidelines were produced, the Company’s actual 2023 Wisconsin tax obligation was $ 1.7 million less than estimated. The state tax benefit noted above consists of the difference between the initial estimate and the actual obligation for 2023. ​ A summary of the sources of differences between income taxes at the federal statutory rate and the provision for income taxes for the years ended December 31 follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 Tax expense at statutory rate ​ $ 18,516 ​ $ 16,698 ​ $ 20,747 Increase (decrease) in taxes resulting from: ​ ​ ​ ​ ​ ​ Tax-exempt interest ​ ( 1,317 ) ​ ( 1,075 ) ​ ( 995 ) State taxes (net of federal benefit) ​ 153 ​ ( 1,375 ) ​ 2,685 Cash surrender value of life insurance ​ ( 604 ) ​ ( 455 ) ​ ( 322 ) ESOP dividend ​ ( 292 ) ​ ( 88 ) ​ ( 88 ) Nondeductible expenses associated with acquisition ​ 124 ​ — ​ 61 Change in valuation allowance ​ 87 ​ ( 616 ) ​ 2,447 Other ​ 7 ​ 861 ​ ( 255 ) Total provision for income taxes ​ $ 16,674 ​ $ 13,950 ​ $ 24,280 ​ State taxes were paid to Minnesota, Michigan, and Florida, and in each of these states the amounts paid were immaterial to these financial statements. ​ ​ 104 Table of Contents Deferred income taxes are provided for the temporary differences between the financial reporting basis and the tax basis of the Company’s assets and liabilities. Deferred taxes are included in other liabilities of the balance sheet. The major components of the net deferred tax asset (liability) as of December 31 are presented below (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2025 ​ 2024 Deferred tax assets: ​ ​ ​ ​ ​ Premises and equipment ​ $ 571 ​ $ 477 Allowance for credit losses ​ 12,834 ​ 12,759 Compensation ​ ​ 617 ​ ​ 619 Purchase accounting ​ ​ 1,840 ​ ​ 2,591 Unrealized loss on securities available for sale ​ 2,350 ​ 3,497 Net operating loss carry forward ​ 1,100 ​ 1,086 Other ​ 230 ​ 353 Total deferred tax assets ​ 19,542 ​ 21,382 Deferred tax liabilities: ​ ​ ​ ​ Investment discount accretion ​ ( 1,771 ) ​ ( 1,516 ) Mortgage servicing rights ​ ( 3,698 ) ​ ( 3,622 ) Other investments ​ ( 1,173 ) ​ ( 911 ) Other real estate owned ​ — ​ ( 45 ) Investment in minority owned subsidiaries ​ ​ ( 1,202 ) ​ ​ ( 1,114 ) Goodwill and other intangibles ​ ( 4,249 ) ​ ( 5,312 ) Total deferred tax liabilities ​ ( 12,093 ) ​ ( 12,520 ) Valuation allowance ​ ​ ( 2,976 ) ​ ​ ( 3,063 ) Net deferred tax asset ​ $ 4,473 ​ $ 5,799 ​ In assessing the ability of the Company to realize the benefit of the deferred tax assets, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. Management considers the scheduled reversal of deferred tax liabilities, availability of operating loss carrybacks, projected future taxable income, and tax planning strategies in making this assessment. Based upon the level of historical taxable income and projections for future taxable income over the periods which deferred tax assets are deductible, management believes it is more likely than not the Company will generate sufficient federally taxable income to realize the benefits of these deductible differences at December 31, 2025. Due to legislation during 2023 related to exempting interest income on significant portions of the Company’s loan portfolio to taxability in the state of Wisconsin, however, management estimates that future state taxable income will be insufficient to fully realize the benefits of these deductible differences, resulting in a valuation allowance of $ 3.0 million and $ 3.1 million on the net deferred tax asset related to state income taxes at December 31, 2025 and 2024, respectively. Tax effects from an uncertain tax position can be recognized in the financial statements only if the position is more likely than not to be sustained on audit, based on the technical merits of the position. The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more likely than not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. When applicable, interest and penalties on uncertain tax positions are calculated based on the guidance from the relevant tax authority and included in income tax expense. At December 31, 2025 and 2024, there was no liability for uncertain tax positions. Federal income tax returns for 4 years ended December 31, 2022 through 2025 remain open and subject to review by applicable tax authorities. State income tax returns for 5 years ended December 31, 2021 through 2025 remain open and subject to review by applicable tax authorities. Note 17 Employee Benefit Plans Employee Stock Ownership Plan The Company has a defined contribution profit sharing 401(k) plan which includes the provisions for an employee stock ownership plan (“ESOP”). The plan is available to all employees over 18 years of age after completion of three months of service. Employees participating in the plan may elect to defer a minimum of 2 % of compensation up to the limits specified 105 Table of Contents by law. All participants of the 401(k) plan are eligible for the ESOP and may allocate their contributions to purchase shares of the Company’s stock. As of December 31, 2025 and 2024, the plan held 183,622 and 221,214 shares, respectively. These shares are included in the calculation of the Company’s earnings per share. The Company may make discretionary contributions up to the limits established by IRS regulations. The Company discretionary match was 60 % of participant contributions up to 10 % of the employee’s salary in 2025 and 2024, and 35 % of participant contributions up to 10 % of the employee’s salary in 2023. With the increase in discretionary match starting in 2024, the Company discontinued the discretionary contributions to the plan. Total expense associated with the plans was approximately $ 1.5 million, $ 1.3 million and $ 1.6 million in 2025, 2024 and 2023, respectively. Share-based Compensation The Company has made restricted share grants during 2025, 2024 and 2023 pursuant to the Bank First Corporation 2020 Equity Plan. The purpose of the Plan is to provide financial incentives for selected employees and for the non-employee Directors of the Company, thereby promoting the long-term growth and financial success of the Company. The Company stock to be offered under the Plan pursuant to Stock Appreciation Rights, performance unit awards, and restricted stock and unrestricted Company stock awards must be Company stock previously issued and outstanding and reacquired by the Company. The number of shares of Company stock that may be issued pursuant to awards under the 2020 Plan shall not exceed, in the aggregate, 700,000 . As of December 31, 2025, 124,570 shares of Company stock has been awarded under the 2020 Plan. Compensation expense for restricted stock is based on the fair value of the awards of Bank First Corporation common stock at the time of grant. The value of restricted stock grants that are expected to vest is amortized into expense over the vesting periods of the respective grants. For the years ended December 31, 2025, 2024 and 2023, compensation expense of $ 2.1 million, $ 2.2 million and $ 2.1 million, respectively, was recognized related to restricted stock awards. As of December 31, 2025, there was $ 2.2 million of unrecognized compensation cost related to non-vested restricted stock awards granted under the plan. That cost is expected to be recognized over a weighted average period of 1.25 years. The aggregate grant date fair value of restricted stock awards that vested during 2025 was approximately $ 2.1 million. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ For the period ended ​ For the period ended ​ ​ December 31, 2025 ​ December 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ Weighted- ​ ​ ​ ​ ​ ​ ​ Weighted- ​ ​ ​ ​ Average Grant- ​ ​ ​ Average Grant- ​ ​ Shares ​ Date Fair Value ​ Shares ​ Date Fair Value Restricted Stock ​ ​ ​ ​ ​ ​ Outstanding at beginning of period 52,634 ​ $ 79.27 58,196 ​ $ 72.28 Granted 23,616 ​ 105.76 24,581 ​ 85.85 Vested ( 28,290 ) ​ 75.74 ( 30,143 ) ​ 71.14 Forfeited or cancelled ( 1,233 ) ​ 80.17 — ​ — Outstanding at end of period 46,727 ​ $ 94.77 52,634 ​ $ 79.27 ​ Deferred Compensation Plan The Company has a deferred compensation agreement with one of its former executive officers. The benefits were payable beginning June 30, 2009, the date of termination of employment with the Company via retirement. The estimated annual cash benefit payment upon retirement at the age of 70 under the salary continuation plan is $ 108,011 . The payoff is for the participant’s lifetime and is guaranteed to the participant or their surviving beneficiary for a minimum of 15 years. Related expense for this agreement was approximately $ 0.1 million for the years ended December 31, 2025 and 2024 and negligible for 2023. Note 18 Stockholders’ Equity and Regulatory Matters The Bank, as a national bank, is subject to the dividend restrictions set forth by the Office of the Comptroller of the Currency. Under such restrictions, the Bank may not, without the prior approval of the Office of the Comptroller of the Currency, declare dividends in excess of the sum of the current year’s earnings (as defined) plus the retained earnings (as defined) from the prior two years. The dividends that the Bank could declare without the prior approval of the Office of the Comptroller of the Currency as of December 31, 2025 totaled approximately $ 61.8 million. The payment of dividends may be further limited because of the need for the Bank to maintain capital ratios satisfactory to applicable regulatory agencies. 106 Table of Contents Banks and certain bank holding companies are subject to regulatory capital requirements administered by federal banking agencies. Capital adequacy guidelines and, additionally for banks, prompt corrective action regulations involve quantitative measures of assets, liabilities, and certain off-balance sheet items calculated under regulatory accounting practices. Capital amounts and classifications are also subject to qualitative judgments by regulators. Failure to meet capital requirements can initiate regulatory action. Under regulatory guidance for non-advanced approaches institutions, the Bank and Company are required to maintain minimum amounts and ratios of common equity Tier I capital to risk-weighted assets, including an additional conservation buffer determined by banking regulators. As of December 31, 2025 and 2024, this buffer was 2.50 %. As of December 31, 2025 and 2024, the Bank and Company met all capital adequacy requirements to which they are subject. ​ Actual and required capital amounts and ratios are presented below (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To Be Well ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum Capital ​ Capitalized Under ​ ​ ​ ​ ​ ​ ​ For Capital ​ Adequacy with ​ Prompt Corrective ​ ​ Actual ​ Adequacy Purposes ​ Capital Buffer ​ Action Provisions ​ ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ Amount ​ ​ ​ Ratio December 31, 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 515,461 13.80 % $ 298,764 8.00 % $ 392,128 10.50 % ​ NA NA ​ Bank ​ $ 460,199 12.33 % $ 298,541 8.00 % $ 391,835 10.50 % $ 373,177 10.00 % Tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 460,067 12.32 % $ 224,073 6.00 % $ 317,437 8.50 % ​ NA NA ​ Bank ​ $ 416,805 11.17 % $ 223,906 6.00 % $ 317,200 8.50 % $ 298,541 8.00 % Common Equity Tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 460,067 12.32 % $ 168,055 4.50 % $ 261,419 7.00 % ​ NA NA ​ Bank ​ $ 416,805 11.17 % $ 167,929 4.50 % $ 261,224 7.00 % $ 242,565 6.50 % Tier 1 capital (to average assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 460,067 10.87 % $ 169,339 4.00 % $ 169,339 4.00 % ​ NA NA ​ Bank ​ $ 416,805 9.85 % $ 169,277 4.00 % $ 169,277 4.00 % $ 211,597 5.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To Be Well ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum Capital ​ Capitalized Under ​ ​ ​ ​ ​ ​ ​ For Capital ​ Adequacy with ​ Prompt Corrective ​ ​ Actual ​ Adequacy Purposes ​ Capital Buffer ​ Action Provisions ​ ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ Amount ​ ​ ​ Ratio ​ ​ ​ Amount ​ ​ ​ Ratio December 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 509,763 14.14 % $ 288,325 8.00 % $ 378,427 10.50 % ​ NA NA ​ Bank ​ $ 438,549 12.18 % $ 288,152 8.00 % $ 378,200 10.50 % $ 360,190 10.00 % Tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 457,749 12.70 % $ 216,244 6.00 % $ 306,346 8.50 % ​ NA NA ​ Bank ​ $ 398,535 11.06 % $ 216,114 6.00 % $ 306,162 8.50 % $ 288,152 8.00 % Common Equity Tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 457,749 12.70 % $ 162,183 4.50 % $ 252,285 7.00 % ​ NA NA ​ Bank ​ $ 398,535 11.06 % $ 162,086 4.50 % $ 252,133 7.00 % $ 234,124 6.50 % Tier 1 capital (to average assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Company ​ $ 457,749 10.96 % $ 167,134 4.00 % $ 167,134 4.00 % ​ NA NA ​ Bank ​ $ 398,535 9.54 % $ 167,019 4.00 % $ 167,019 4.00 % $ 208,774 5.00 % ​ ​ Note 19 Segment Information The Company’s reportable segment is determined by the Chief Executive Officer, who is the designated chief operating decision maker, based upon information provided by the Company’s products and services offered, primarily banking operations. The segment is also distinguished by the level of information provided to the chief operating decision maker, who uses such information to review the performance of various components of the business such as branches, which are then aggregated as operating performance, products and services, and customers are similar. The chief operating decision maker will then evaluate the financial performance of the Company’s business components such as by evaluating significant revenues and expenses and budget to actual results in assessing the Company’s segment and in the determination of allocating resources. The chief decision maker uses revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The chief decision maker uses consolidated net income and return on assets to benchmark the Company against its competitors. The benchmarking analysis, coupled with monitoring of budget to actual results, are used in the assessment of performance and in establishing compensation. Loans, investments, service charges, and deposits in other banks provide the significant revenues in the banking operation. Interest expense, provisions for credit losses, data processing and payroll provide the significant expenses in banking operation. All operations 107 Table of Contents are domestic. Information reported internally for performance assessment by the chief operating decision maker is identical to that which is shown in the Consolidated Statements of Income. ​ Note 20 Commitments and Contingencies The Company enters into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (rate lock commitments). Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. The fair values of the Company’s rate lock commitments to customers as of December 31, 2025 and 2024 were not material and have not been recorded. The notional amount of rate lock commitments at December 31, 2025 and 2024, respectively, was $ 16.9 million and $ 8.2 million. The Bank is party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets. The Bank’s exposure to credit loss is represented by the contractual or notional amount of these commitments. The Bank follows the same credit policies in making commitments as it does for on-balance-sheet instruments. Since some of the commitments are expected to expire without being drawn upon and some of the commitments may not be drawn upon to the total extent of the commitment, the notional amount of these commitments does not necessarily represent future cash requirements. The following commitments were outstanding at December 31 (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Notional Amount ​ ​ ​ ​ December 31, 2025 ​ December 31, 2024 ​ ​ ​ ​ ​ ​ ​ Commitments to extend credit: ​ ​ ​ ​ Fixed ​ $ 41,721 ​ $ 46,856 Variable ​ 723,821 ​ 706,353 Credit card arrangements ​ 26,217 ​ 24,399 Letters of credit ​ 11,708 ​ 11,055 ​ Commitments to extend credit are agreements to lend to a customer at fixed or variable rates as long as there is no violation of any condition established in the contract. Commitments have fixed expiration dates or other termination clauses and may require payment of a fee. The amount of collateral obtained upon extension of credit is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable; inventory; property, plant, and equipment; real estate; and stocks and bonds. Letters of credit include $ 11.7 million of standby letters of credit and no direct pay letters of credit. Standby letters of credit are conditional lending commitments issued by the Company to guaranty the performance of a customer to a third party. Direct pay letters of credit generally are issued to support the marketing of industrial development revenue and housing bonds and provide that all debt service payments will be paid by drawing on the letter of credit. The letter of credit draws are then repaid by draws from the customer’s bank account. Generally, all standby letters of credit issued have expiration dates within one year. The credit risk involved in issuing letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company generally holds collateral supporting these commitments. The majority of the Company’s loans, commitments, and letters of credit have been granted to customers in the Company’s market area. The concentrations of credit by type are set forth in Note 4. Standby letters of credit were granted primarily to commercial borrowers. Management believes the diversity of the local economy will prevent significant losses in the event of an economic downturn. ​ ​ 108 Table of Contents Note 21 Leases In accordance with GAAP, leases where the Company is the lessee are recognized on-balance sheet through a right-of-use (“ROU”) model that requires recognition of a ROU lease asset and liability on the balance sheet for all leases with a term longer than 12 months. Leases are classified as finance or operating, with classification affecting the pattern and classification of expense recognition in the income statement. The Company leases certain properties under operating leases that resulted in the recognition of ROU lease assets of approximately $ 1.6 million and corresponding lease liabilities of similar value on the Company’s Consolidated Balance Sheets as of December 31, 2025 and 2024. Lessee Leases The Company’s lessee leases are operating leases, and consist of leased real estate for branches. Options to extend and renew leases are generally exercised under normal circumstances. Advance notification is required prior to termination, and any noticing period is often limited to the months prior to renewal. Rent escalations are generally specified by a payment schedule, or are subject to a defined formula. The Company also elected the practical expedient to not separate lease and non-lease components for all leases, the majority of which consist of real estate common area maintenance expenses. Generally, leases do not include guaranteed residual values, but instead typically specify that the leased premises are to be returned in satisfactory condition with the Company liable for damages. For operating leases, the lease liability and ROU asset (before adjustments) are recorded at the present value of future lease payments. The Company is electing to utilize the Wall Street Journal Prime Rate on the date of lease commencement as the lease interest rate. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Year Ended (dollars in thousands) ​ ​ ​ December 31, 2025 ​ ​ ​ December 31, 2024 Amortization of ROU Assets - Operating Leases ​ $ ( 2 ) ​ $ ( 2 ) ​ Interest on Lease Liabilities - Operating Leases ​ 87 ​ ​ 87 ​ Operating Lease Cost (Cost resulting from lease payments) ​ 86 ​ ​ 86 ​ Weighted Average Lease Term (Years) - Operating Leases ​ 28.00 ​ ​ 29.00 ​ Weighted Average Discount Rate - Operating Leases ​ 5.50 % ​ 5.50 % ​ A maturity analysis of operating lease liabilities and reconciliation of the undiscounted cash flows to the total operating lease liabilities is as follows (dollar amounts in thousands): ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2025 Operating lease payments due: ​ ​ Within one year ​ $ 94 After one but within two years ​ ​ 94 After two but within three years ​ ​ 94 After three but within four years ​ ​ 94 After four years but within five years ​ ​ 94 After five years ​ ​ 2,855 Total undiscounted cash flows ​ ​ 3,325 Discount on cash flows ​ ​ ( 1,739 ) Total operating lease liabilities ​ $ 1,586 ​ ​ 109 Table of Contents Note 22 Fair Value of Financial Instruments Accounting guidance establishes a fair value hierarchy to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. The standard describes three levels of inputs that may be used to measure fair value. ​ ​ ​ Level 1: Quoted prices (unadjusted) or identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. ​ ​ Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. ​ ​ Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. ​ There were no liabilities measured at fair value on a recurring basis.

For individually evaluated impaired loans, the amount of impairment is based upon the present value of expected future cash flows discounted at the loan’s effective interest rate, the estimated fair value of the underlying collateral for collateral-dependent loans, or the estimated liquidity of the note. For OREO, the fair value is based upon the estimated fair value of the underlying collateral adjusted for the expected costs to sell.

Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. 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. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Consequently, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments, and other factors. These estimates are subjective in nature and involve uncertainties and matters that could affect the estimates. Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business and the value of assets and liabilities that are not considered financial instruments. ​ Deposits with no stated maturities are defined as having a fair value equivalent to the amount payable on demand. This prohibits adjusting fair value derived from retaining those deposits for an expected future period of time. This component, commonly referred to as a deposit base intangible, is neither considered in the above amounts nor is it recorded as an intangible asset on the consolidated balance sheet. Significant assets and liabilities that are not considered financial assets and liabilities include premises and equipment. In addition, the tax ramifications related to the realization of the unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates. 112 Table of Contents Note 23 Parent Company Only Financial Statements Balance Sheets ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31 ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ (In Thousands) Assets ​ ​ ​ ​ ​ Cash and cash equivalents ​ $ 56,042 ​ $ 72,705 Securities ​ ​ 2,574 ​ ​ 1,847 Investment in Bank ​ 600,598 ​ 580,523 Other assets ​ 214 ​ 317 TOTAL ASSETS ​ $ 659,428 ​ $ 655,392 Liabilities and Stockholders’ Equity ​ ​ ​ ​ Liabilities ​ ​ ​ ​ Subordinated notes ​ $ 12,000 ​ $ 12,000 Other liabilities ​ 3,592 ​ 3,709 Total liabilities ​ 15,592 ​ 15,709 Stockholders’ equity: ​ ​ ​ ​ Common stock ​ 115 ​ 115 Additional paid-in capital ​ 333,836 ​ 333,842 Retained earnings ​ 416,997 ​ 398,002 Treasury stock, at cost ​ ( 102,088 ) ​ ( 82,925 ) Accumulated other comprehensive loss ​ ( 5,024 ) ​ ( 9,351 ) Total stockholders’ equity ​ 643,836 ​ 639,683 TOTAL LIABILITIES AND STOCKHOLDERS’ EQUITY ​ $ 659,428 ​ $ 655,392 ​ ​ Statements of Income ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Years Ended December 31 ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 ​ ​ (In Thousands) Income: ​ ​ ​ ​ ​ ​ ​ ​ ​ Dividends received from Bank ​ $ 57,357 ​ $ 84,561 ​ $ 68,573 Equity in undistributed earnings of subsidiaries ​ 15,779 ​ ( 16,959 ) ​ 10,271 Other income ​ 743 ​ 144 ​ — Total income ​ 73,879 ​ 67,746 ​ 78,844 Other expenses ​ 2,997 ​ 2,946 ​ 5,951 Benefit for income taxes ​ ( 614 ) ​ ( 763 ) ​ ( 1,621 ) Net income ​ $ 71,496 ​ $ 65,563 ​ $ 74,514 ​ 113 Table of Contents Statements of Cash Flows ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Years Ended December 31, ​ ​ ​ ​ 2025 ​ ​ ​ 2024 ​ ​ ​ 2023 ​ ​ (In thousands) Cash flow from operating activities: ​ ​ ​ ​ ​ ​ ​ ​ ​ Net income ​ $ 71,496 ​ $ 65,563 ​ $ 74,514 Adjustments to reconcile net income to net cash (used in) provided by operating activities: ​ ​ ​ ​ ​ ​ Stock compensation ​ 2,136 ​ 2,172 ​ 2,142 Equity in earnings of subsidiaries (includes dividends) ​ ( 73,136 ) ​ ( 67,602 ) ​ ( 78,844 ) Changes in other assets and liabilities: ​ ​ ​ ​ ​ ​ Other assets ​ ( 594 ) ​ ( 11 ) ​ 403 Other liabilities ​ ( 116 ) ​ 2,031 ​ 230 Net cash (used in) provided by operating activities ​ ( 214 ) ​ 2,153 ​ ( 1,555 ) Cash flows from investing activities, net of effects of business combination: ​ ​ ​ ​ ​ ​ Dividends received from Bank ​ 57,357 ​ 84,561 ​ 69,982 Dividends received from Veritas ​ — ​ — ​ 37 Net cash used in business combination ​ — ​ — ​ ( 4,554 ) Proceeds from other investments ​ — ​ — ​ 248 Net cash provided by investing activities ​ 57,357 ​ 84,561 ​ 65,713 Cash flows from financing activities, net of effects of business combination: ​ ​ ​ ​ ​ ​ Repayment of junior subordinated debentures ​ — ​ ( 4,124 ) ​ ( 8,248 ) Repayment of subordinate notes ​ — ​ — ​ ( 11,500 ) Cash dividends paid ​ ( 52,501 ) ​ ( 15,562 ) ​ ( 11,959 ) Issuance of common stock ​ 737 ​ 245 ​ 195 Repurchase of common stock ​ ( 22,042 ) ​ ( 31,928 ) ​ ( 10,046 ) Net cash used in financing activities ​ ( 73,806 ) ​ ( 51,369 ) ​ ( 41,558 ) Net (decrease) increase in cash and cash equivalents ​ ( 16,663 ) ​ 35,345 ​ 22,600 Cash and cash equivalents at beginning ​ 72,705 ​ 37,360 ​ 14,760 Cash and cash equivalents at end ​ $ 56,042 ​ $ 72,705 ​ $ 37,360 ​ ​ 114 Table of Contents Note 24 Earnings Per Common Share See Note 1 for the Company’s accounting policy regarding per share computations.
