**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**(Unaudited)**

**Note 1.Summary of Significant Accounting Policies**

**Basis of Presentation:**

The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial reporting and with instructions for Form 10-Q and Regulation S-X. These financial statements include all adjustments (consisting of normal recurring accruals) which in the opinion of management are considered necessary for the fair presentation of the financial position and results of operations for the periods shown. While the chief operating 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. Although the loan activity of the Bank is diversified with commercial and agricultural loans, real estate loans, automobile, installment and other consumer loans, the Bank's credit is concentrated in real estate loans. Accordingly, the management of the Company considers that it operates as one business segment, a commercial bank.

Operating results for the nine month period ended September 30, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending December 31, 2025. For further information, refer to the consolidated financial statements and footnotes thereto included in the Form 10-K Annual Report of Hills Bancorporation and subsidiary (the "Company") for the year ended December 31, 2024 filed with the Securities Exchange Commission on March 14, 2025. The consolidated balance sheet as of December 31, 2024, has been derived from the audited consolidated financial statements for that period.

The Company evaluated subsequent events through the filing date of its quarterly report on Form 10-Q with the SEC.

**Accounting Estimates:** 

The preparation of consolidated financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amount of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

**Certain Significant Estimates:** 

The allowance for credit losses involves certain significant estimates made by management. These estimates are reviewed by management routinely and it is reasonably possible that circumstances that exist at September 30, 2025 may change in the near-term and the effect could be material to the consolidated financial statements. Actual amounts and values as of the balance sheet dates may be materially different than the amounts and values reported due to the inherent uncertainty in the estimation process.

**Revenue Recognition:**

Accounting Standards Codification ("ASC") 606, *Revenue from Contracts with Customers* ("ASC 606"), establishes principles for reporting information about the nature, amount, timing and uncertainty of revenue and cash flows arising from the Company's contracts to provide goods or services to customers. The core principle requires an entity to recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration that it expects to be entitled to receive in exchange for those goods or services recognized as performance obligations are satisfied.

The majority of the Company's revenue-generating transactions are not subject to ASC 606, including revenue generated from financial instruments, such as loans, letters of credit and investment securities. Interest income on loans and investment securities is recognized on the accrual method in accordance with written contracts.

Descriptions of the Company's revenue-generating activities that are within the scope of ASC 606 are the following: Service charges and fees on deposit accounts represent general service fees for monthly account maintenance and activity- or transaction-based fees and consist of transaction-based revenue which includes interchange income, time-based revenue (service period), item-based revenue or some other individual attribute-based revenue. Revenue is recognized when the

**(Unaudited)**

Company's performance obligation is completed which is generally monthly for account maintenance services or when a transaction has been completed (such as a wire transfer). Payment for such performance obligations are generally received at the time the performance obligations are satisfied. Trust income represents monthly fees due from wealth management customers as consideration for managing the customers' assets. Wealth management and trust services include custody of assets, investment management, fees for trust services and similar fiduciary activities. Revenue is recognized when our performance obligation is completed each month, which is generally the time that payment is received.

A contract asset balance occurs when an entity performs a service for a customer before the customer pays consideration (resulting in a contract receivable) or before payment is due (resulting in a contract asset). A contract liability balance is an entity's obligation to transfer a service to a customer for which the entity has already received payment (or payment is due) from the customer. As of September 30, 2025 and December 31, 2024, the Company did not have any significant contract balances.

An entity is required to capitalize, and subsequently amortize into expense, certain incremental costs of obtaining a contract with a customer if these costs are expected to be recovered. The incremental costs of obtaining a contract are those costs that an entity incurs to obtain a contract with a customer that it would not have incurred if the contract had not been obtained (for example, sales commission). The Company utilizes the practical expedient which allows entities to immediately expense contract acquisition costs when the asset that would have resulted from capitalizing these costs would have been amortized in one year or less. The Company has not incurred or capitalized any contract acquisition costs as of September 30, 2025 and December 31, 2024.

<u>Tax credit real estate</u>: Tax credit real estate represents three multi-family rental properties, three assisted living rental properties, a multi-tenant rental property for persons with disabilities, and a multi-family senior living rental property, all of which are affordable housing projects as of September 30, 2025. In addition, in July 2024, the Company made a tax equity investment in an entity to provide for the historic preservation of a mixed use property in Cedar Rapids, Iowa. The Company has a 99% or greater limited interest in each limited partnership or company. The investment in each was completed after the projects had been developed by the general partner or managing member. On a regular basis, the Company evaluates recoverability of the carrying value of the tax credit real estate investments to determine if there are indications of impairment. This is measured by a comparison of the carrying amount of the investments to the future undiscounted cash flows expected to be generated by the investment properties, including the low-income housing tax credits and any estimated proceeds from eventual disposition. If there is an indication of impairment, a valuation allowance would be established with a charge to expense. There were no indications of impairment based on management's evaluation and therefore no valuation allowance was determined necessary as of September 30, 2025. Depreciation expense is provided on a straight-line basis over the estimated useful life of the assets. Expenditures for normal repairs and maintenance are charged to expense as incurred.

The investments in tax credit real estate are recorded for all years presented using the equity method of accounting, with the exception of the investments in the affordable housing project and historic preservation project described below. The operations of the properties are not expected to contribute significantly to the Company's income before income taxes. However, the properties do contribute in the form of income tax credits, which lowers the Company's effective tax rate. Once established, the credits on each property last for ten years, five years for the historic preservation property, and are passed through from the limited partnerships or entity to the Company and reduces the consolidated federal tax liability of the Company.

In February 2021, the Company provided construction financing and contributed capital of $4.18 million to Del Ray Ridge LP, as limited partner, which owns and operates an affordable housing property in Iowa City, Iowa. The Company accounts for the investment in this tax credit real estate using the proportional amortization method as provided for under Accounting Standards Codification (ASC) 323-740. The investment qualifies for the proportional amortization method as it meets all of the criteria under ASC 323-740-25-1. Substantially all of the projected benefits are from tax credits and other tax benefits due to the minimum buyout clause included in the partnership agreement.

In July 2024, the Company provided construction financing and contributed capital of $2.38 million to SLE Iowa Building, LC, as investor member, which owns and operates a historically preserved mixed use property in Cedar Rapids, Iowa. Additional capital contributions of $1.19 million and $1.23 million were made in the quarters ended September 30, 2025 and June 30, 2025, respectively. The Company accounts for the investment in this tax credit real estate using the proportional amortization method as provided for under Accounting Standards Codification (ASC) 323-740. The investment qualifies for the proportional amortization method as it meets all of the criteria under ASC 323-740-25-1. Substantially all of the projected benefits are from tax credits and other tax benefits due to the minimum buyout clause included in the operating agreement.

<u>Available-for-sale debt securities and the allowance for credit losses on available-for-sale debt securities</u>: Available-for-sale ("AFS") securities consist of debt securities not classified as trading or held to maturity. Available-for-sale securities are stated at fair value, and unrealized holding gains and losses, net of the related deferred tax effect, are reported as a separate component of stockholders' equity. There were no trading or held to maturity securities as of September 30, 2025 or 2024. Fair value measurement is based upon quoted market prices in active markets, if available. If quoted prices in active markets are not available, fair value is measured using pricing models or other model-based valuation techniques such as present value of future cash flows, which consider prepayment assumptions and other factors such as credit losses and market liquidity. Unrealized gains and losses are excluded from earnings and reported, net of tax, in other comprehensive income ("OCI"). Premiums on debt securities are amortized to the earliest call date and discounts on debt securities are accreted over the period to maturity of those securities. The method of amortization results in a constant effective yield on those securities (the interest method). Gains and losses on the sale of securities are recorded on the trade date and are determined using the specific identification method.

AFS debt securities in unrealized loss positions are evaluated for impairment related to credit losses at least quarterly. For AFS debt securities, a decline in fair value due to credit loss results in recording an allowance for credit losses to the extent the fair value is less than the amortized cost basis. Declines in fair value that have not been recorded through an allowance for credit losses, such as declines due to changes in market interest rates, are recorded through other comprehensive income, net of applicable taxes.

Impairment may result from credit deterioration of the issuer or collateral underlying the security. In performing an assessment of whether any decline in fair value is due to a credit loss, all relevant information is considered at the individual security level. For asset-backed securities performance indicators considered related to the underlying assets include default rates, delinquency rates, percentage of nonperforming assets, debt-to-collateral ratios, third-party guarantees, current levels of subordination, vintage, geographic concentration, analyst reports and forecasts, credit ratings and other market data. In assessing whether a credit loss exists, we compare the present value of cash flows expected to be collected from the security with the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses is recorded, limited to the amount the fair value is less than amortized cost basis.

If we intend to sell a debt security or more likely than not we will be required to sell the security before recovery of its amortized cost basis, the debt security is written down to its fair value and the write down is charged against the allowance for credit losses with any incremental impairment reported in earnings.

Accrued interest receivable on AFS debt securities, stock of the Federal Home Loan Bank, and Federal Reserve excess balance account totaled $7.19 million and $6.10 million at September 30, 2025 and December 31, 2024, respectively, and is excluded from the estimate of credit losses.

Stock of the Federal Home Loan Bank is carried at cost. The Company has evaluated the stock and determined there is no impairment.

<u>Loans held for sale</u>: Loans held for sale are stated at the lower of aggregate cost or estimated fair value. Loans are sold on a non-recourse basis with servicing released and gains and losses are recognized based on the difference between sales proceeds and the carrying value of the loan. The Company has had very few experiences of repurchasing loans previously sold into the secondary market. A specific reserve was not considered necessary based on the Company's historical experience with repurchase activity.

<u>Loans held for investment</u>: Loans that management has the intent and ability to hold for the foreseeable future or until maturity or payoff are reported at amortized cost net of the allowance for credit losses ("ACL"). Amortized cost is the principal balance outstanding, net of deferred loan fees and costs. Accrued interest receivable on loans held for investment totaled $18.07 million and $15.30 million at September 30, 2025 and December 31, 2024, respectively, and is excluded from the estimate of credit losses. Interest income is accrued on the unpaid principal balance. Nonrefundable loan fees and origination costs are deferred and recognized as a yield adjustment over the life of the related loan.

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 payments of interest or principal when they become due, which is generally when a loan is 90 days or

**(Unaudited)**

more past due unless the loan is well secured and in the process of collection. When a loan is placed on nonaccrual status, all previously accrued and unpaid interest is reversed against interest income. Loans are returned to an accrual status when all of the principal and interest amounts contractually due are brought current and repayment of the remaining contractual principal and interest is expected. A loan may also return to accrual status if additional collateral is received from the borrower and, in the opinion of management, the financial position of the borrower indicates that there is no longer any reasonable doubt as to the collection of the amount contractually due. Payment received on nonaccrual loans are applied first to principal. Once principal is recovered, any remaining payments received are applied to interest income.

The policy for charging off loans is consistent throughout all loan categories. A loan is charged off based on criteria that includes but is not limited to: delinquency status, financial condition of the entire customer credit line and underlying collateral coverage, economic or external conditions that might impact full repayment of the loan, legal issues, overdrafts, and the customer's willingness to work with the Company.

<u>Allowance for credit losses for loans held for investment</u>: The allowance for credit losses is an estimate of the expected losses over the remaining life of the Company's existing loans held for investment portfolio. The allowance for credit losses for loans held for investment, as reported in our consolidated balance sheet, is adjusted by a credit loss expense, which is reported in earnings, and reduced by the charge-off of loan amounts, net of recoveries.

The loan loss estimation process involves procedures to appropriately consider the unique characteristics of loan portfolio segments which consist of agricultural, 1 to 4 family first and junior liens, commercial, and consumer lending. These segments are further disaggregated into loan classes, the level at which credit risk is monitored. For each of these pools, the Company generates cash flow projections at the instrument level wherein payment expectations are adjusted for estimated prepayment speed, curtailments, time to recovery, probability of default, and loss given default. The modeling of expected prepayment speeds, curtailment rates, and time to recovery are based on historical internal data. The following provides the credit quality indicators and risk elements that are most relevant and most carefully considered and monitored for each loan portfolio segment.

*Agricultural -* Agricultural operating loans include loans made to finance agricultural production and other loans to farmers and farming operations. Agricultural loans also include mortgage loans secured by farmland. Agricultural operating loans, most of which are secured by crops and machinery, are provided to finance capital improvement and farm operations as well as acquisitions of livestock and machinery. The ability of the borrower to repay may be affected by many factors outside of the borrower's control including adverse weather conditions, loss of livestock due to disease or other factors, declines in market prices for agricultural products and the impact of government regulations. The ultimate repayment of agricultural operating loans is dependent upon the profitable operation or management of the agricultural entity. Agricultural operating loans generally have a term of one year and may have a fixed or variable rate. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate and the National real gross domestic product (GDP) as of September 30, 2025 and December 31, 2024.

Mortgage loans secured by farmland are made to individuals and businesses within the Company's trade area. The primary source of repayment is the cash flow generated by the collateral underlying the loan. The secondary repayment source would be the liquidation of the collateral. Terms for real estate loans secured by farmland range from one to ten years with an amortization period of 25 years or less. Generally, interest rates are fixed for mortgage loans secured by farmland. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate and the National real gross domestic product as of September 30, 2025 and December 31, 2024.

*1 to 4 Family First and Junior Liens -* The 1 to 4 family first and junior liens portfolio segment is comprised of the single family and home equity loan classes, which are underwritten after evaluating a borrower's capacity to repay, credit, and collateral. Several factors are considered when assessing a borrower's capacity, including the borrower's employment, income, current debt, assets, and level of equity in the property. Credit refers to how well a borrower manages their current and prior debts as documented by a credit report that provides credit scores and the borrower's current and past information about their credit history. Collateral refers to the type and use of property, occupancy, and market value. Property appraisals are obtained to assist in evaluating collateral. Loan-to-property value and debt-to-income ratios, loan amount, and lien position are also considered in assessing whether to originate a loan. These borrowers are particularly susceptible to downturns in economic trends such as conditions that negatively affect

housing prices and demand and levels of unemployment. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate as of September 30, 2025 and December 31, 2024.

*Commercial -* The commercial loan portfolio segment is comprised of the commercial real estate mortgage including obligations of states and political subdivisions, multifamily residential mortgage, construction/land development and commercial and financial loan classes, whose underwriting standards consider the factors described for single family and home equity loan classes as well as others when assessing the borrower's and associated guarantors or other related party's financial position. These other factors include assessing liquidity, the level and composition of net worth, leverage, considering all other lender amounts and position, an analysis of cash expected to flow through the obligors including the outflow to other lenders, vacancies and prior experience with the borrower. This information is used to assess adequate financial capacity, profitability, and experience. Ultimate repayment of these loans is sensitive to interest rate changes, general economic conditions, liquidity, and availability of long-term financing. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate and the National real gross domestic product as of September 30, 2025 and December 31, 2024.

*Consumer Lending -* The Company offers consumer loans to individuals including personal loans and automobile loans. These consumer loans typically have shorter terms, lower balances, higher yields and higher risks of default than real estate-related loans. Consumer collections are dependent on the borrower's continuing financial stability and are more likely to be affected by adverse personal circumstances. Collateral for these loans generally includes automobiles, boats, recreational vehicles and real estate. However, depending on the overall financial condition of the borrower, some loans are made on an unsecured basis. The collateral securing these loans may depreciate over time, may be difficult to recover and may fluctuate in value based on condition. Key economic forecasts used in estimating expected credit losses for this segment include the Iowa unemployment rate and the National real gross domestic product as of September 30, 2025 and December 31, 2024.

The allowance level is influenced by loan volumes, loan credit quality indicator migration or delinquency status, historic loss experience and other conditions influencing loss expectations, such as reasonable and supportable forecasts of economic conditions. The methodology for estimating the amount of expected credit losses reported in the allowance for credit losses has two basic components: first, a pooled component for estimated expected credit losses for pools of loans that share similar risk characteristics; and second, an asset-specific component involving individual loans that do not share risk characteristics with other loans and the measurement of expected credit losses for such individual loans. Depending on the nature of the pool of financial assets with similar risk characteristics, the Company uses a discounted cash flow method or remaining life method to estimate expected credit losses.

*Discounted cash flow method*: In estimating the component of the allowance for credit losses for loans that share similar risk characteristics with other loans, such loans are segregated into loan classes. Loans are designated into loan classes based on loans pooled by product types and similar risk characteristics or areas of risk concentration. In determining the allowance for credit losses, we derive an estimated credit loss assumption from a model that categorizes loan pools based on loan type and purpose. This model calculates an expected loss percentage for each loan class by considering the probability of default, using life-of-loan analysis periods for all loan segments, and the historical severity of loss, based on the aggregate net lifetime losses incurred per loan class. The default and severity factors used to calculate the allowance for credit losses for loans that share similar risk characteristics with other loans are adjusted for differences between the historical period used to calculate historical default and loss severity rates and expected conditions over the remaining lives of the loans in the portfolio related to: (1) lending policies and procedures; (2) international, national, regional and local economic business conditions and developments that affect the collectability of the portfolio; (3) the nature and volume of the loan portfolio including the terms of the loans; (4) the experience, ability, and depth of the lending management and other relevant staff; (5) the volume and severity of past due and adversely classified or graded loans and the volume of nonaccrual loans; (6) the quality of our loan review system; (7) the value of underlying collateral for collateral-dependent loans; (8) the existence and effect of any concentrations of credit and changes in the level of such concentrations; and (9) the effect of external factors such as competition and legal and regulatory requirements on the level of estimated credit losses in the existing portfolio. Such factors are used to adjust the historical probabilities of default and severity of loss so that they reflect management expectation of future conditions based on a reasonable and supportable forecast. Management utilizes a qualitative factor framework to provide a qualitative estimate of the expected credit losses inherent in the loan portfolio in relation to potential limitations of the quantitative model. The framework provides for a level of risk approach to measure risk in each loan segment that may not be captured in the quantitative methodology, including improved risk environment, no additional risk, minimal additional risk, moderate risk and major or significant additional risk. The framework also includes a weighting component for management to consider which qualitative

**(Unaudited)**

factors would have the highest impact on potential loan losses within each loan segment. Management uses the qualitative factor framework within the allowance for credit losses calculation to assess the risk level environment for each qualitative factor and weightings for each loan segment which is supported by various information including publicly available information, internal information specifically developed by management, or other relevant and reliable information.

The Company uses regression analysis of historical internal and peer data to determine which variables are best suited to be economic variables utilized when modeling lifetime probability of default and loss given default. This analysis also determines how expected probability of default and loss given default will react to forecasted levels of the economic variables.

For all DCF models, management has determined that four quarters represents a reasonable and supportable forecast period and reverts back to a historical loss rate over twelve quarters on a straight-line basis. Other internal and external indicators of economic forecasts are also considered by management when developing the forecast metrics.

*Remaining life method:* Expected credit losses for credit cards and overdrafts are determined through use of the remaining life method. The remaining life method utilizes average annual charge-off rates and remaining life to estimate the allowance for credit losses. This is done by estimating the amount and timing of principal payments expected to be received as payment for the balance outstanding as of the reporting period and applying those principal payments against the balance outstanding as of the reporting period along with the average annual charge-off rate until the expected payments have been fully allocated. Management applies the same qualitative factor framework for the remaining life method loan portfolios as the framework used for the discounted cash flow method loan portfolios.

*Collateral dependent financial assets*: For a loan that does not share risk characteristics with other loans, expected credit loss is measured based on net realizable value, that is, the difference between the discounted value of the expected future cash flows, based on the original effective interest rate, and the amortized cost basis of the loan. For these loans, we recognize expected credit loss equal to the amount by which the net realizable value of the loan is less than the amortized cost basis of the loan (which is net of previous charge-offs and deferred loan fees and costs), except when the loan is collateral dependent, that is, when the borrower is experiencing financial difficulty and repayment is expected to be provided substantially through the operation or sale of the collateral. In these cases, expected credit loss is measured as the difference between the amortized cost basis of the loan and the fair value of the collateral. The fair value of the collateral is adjusted for the estimated cost to sell if repayment or satisfaction of a loan is dependent on the sale (rather than only on the operation) of the collateral.

The Company's estimate of the ACL reflects losses expected over the contractual life of the assets, adjusted for estimated prepayments or curtailments. The contractual term does not consider extensions, renewals or modifications unless the Company has identified a modification including a concession to a borrower experiencing financial difficulties. A modification of a loan to a borrower experiencing financial difficulties occurs when two conditions are met: 1) the borrower is experiencing financial difficulty and 2) concessions are made for the borrower's benefit that would not otherwise be considered for a borrower or transaction with similar credit risk characteristics.

<u>Allowance for credit losses on off-balance sheet credit exposures, including unfunded loan commitments:</u> The Company maintains a separate allowance for credit losses from off-balance-sheet credit exposures, including unfunded loan commitments, which is disclosed on the balance sheet. Management estimates the amount of expected losses by calculating a commitment usage factor over the contractual period for exposures that are not unconditionally cancellable by the Company and applying the loss factors used in the ACL methodology to the results of the usage calculation to estimate the liability for credit losses related to unfunded commitments for each loan type. No credit loss estimate is reported for off-balance-sheet (OBS) credit exposures that are unconditionally cancellable by the Company, such as credit card receivables, or for undrawn amounts under such arrangements that may be drawn prior to the cancellation of the arrangement. The allowance for credit losses on OBS credit exposures is adjusted as credit loss expense. Categories of OBS credit exposures correspond to the loan portfolio segments described previously.

**Effect of New Financial Accounting Standards:**

In March 2023, the FASB issued ASU 2023-02, Investments - Equity Method and Joint Ventures (Topic 323) *Accounting for Investments in Tax Credit Structures Using Proportional Amortization Method*. The FASB is issuing this ASU to allow reporting entities to consistently account for equity investments made primarily for the purposes of receiving income tax credits and other income tax benefits. The ASU permits reporting entities to elect to account for tax equity investments, regardless of the tax credit program from which the income tax credits are received, using the proportional amortization method if certain

Early adoption is permitted for all entities in any interim period. If an entity adopts the amendments in an interim period, it shall adopt them as of the beginning of the fiscal year that includes that interim period. The adoption of the ASU on a prospective basis by the Company on January 1, 2024 did not have a material impact on the financial statements.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280) *Improvements to Reportable Segment Disclosures*. The FASB is issuing this ASU to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. For public business entities, the amendments are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. A public entity should apply the amendments in this Update retrospectively to all prior periods presented in the financial statements. Upon transition, the segment expense categories and amounts disclosed in the prior periods should be based on the significant segment expense categories identified and disclosed in the period of adoption. The Company adopted the ASU on January 1, 2024 for the annual period ending December 31, 2024. See disclosure in Note 13.

In March 2024, the FASB issued ASU 2024-01, Compensation - Stock Compensation (Topic 718) *Scope Application of Profits Interest and Similar Awards*. The FASB is issuing this ASU to improve generally accepted accounting principles by adding an illustrative example to demonstrate how an entity should apply the scope guidance to determine whether profits interest and similar awards ("profit interest awards") should be accounted for in accordance with Topic 718, Compensation - Stock Compensation. The illustrative example is intended to reduce 1) complexity in determining whether a profits interest award is subject to the guidance in Topic 718 and 2) existing diversity in practice. For public business entities, the amendments are effective for annual periods beginning after December 15, 2024, and interim periods within those annual periods. Early adoption is permitted for both interim and annual financial statements that have not yet been issued or made available for issuance. The amendments in this Update should be applied either (1) retrospectively to all prior periods presented in the financial statements or (2) prospectively to profits interest and similar awards granted or modified on or after the date at which the entity first applies the amendments. The adoption of the ASU on a prospective basis by the Company on January 1, 2025 did not have a material impact on the financial statements.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740) *Improvements to Income Tax Disclosures*. The FASB is issuing this ASU to enhance the transparency and decision usefulness of income tax disclosures. The amendments in this ASU require that public business entities on an annual basis disclose specific categories in the rate reconciliation, provide additional information for reconciling items that meet a quantitative threshold, disclose the amount of income taxes paid disaggregated by federal, state and foreign taxes and other disclosures. For public business entities, the amendments are effective for annual periods beginning after December 15, 2024. Early adoption is permitted for annual financial statements that have not yet been issued or made available for issuance. The amendments in this ASU should be applied on a prospective basis. The Company is in the process of evaluating the impact of this ASU on the financial statements.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): *Disaggregation of Income Statement Expenses.* This ASU requires public companies to disclose, in the notes to financial statements, specified information about certain costs and expenses at each interim and annual reporting period.

The Company considered the following information in reaching the conclusion that the unrealized losses disclosed in the table above are not attributable to credit losses. None of the unrealized losses in the above table was due to the deterioration in the credit quality of any of the issues that might result in the non-collection of contractual principal and interest. The unrealized losses are due to changes in interest rates. The Company has not recognized any unrealized loss in income because management does not have the intent to sell the securities included in the previous table. Management has concluded that it is more likely than not that the Company will not be required to sell these securities prior to recovery of the amortized cost basis. The securities are of high credit quality (investment grade credit ratings) and principal and interest payments are made timely with no payments past due as of September 30, 2025. The fair value is expected to recover as the securities approach maturity. The U.S. Treasury and other securities are issued and guaranteed by U.S. government-sponsored entities and agencies. The MBS and CMOs have implied U.S. government guarantees of the agency securities. The Company evaluates if a credit loss exists by monitoring to ensure it has adequate credit support considering the nature of the investment, number and significance of investments in an unrealized loss position, collectability or delinquency issues, the underlying financial statements of the issuers, credit ratings and subsequent changes thereto, and other available relevant information. Considering the above factors, management has determined that no allowance for credit losses is necessary for the securities portfolio as of September 30, 2025.

Credit loss expense for off-balance sheet credit exposures is included in credit loss expense on the consolidated statement of income for the three and nine months ended September 30, 2025 and 2024.

Management regularly reviews loans in the portfolio to assess credit quality indicators and to determine appropriate loan classification and grading in accordance with applicable bank regulations. The Company's risk rating methodology assigns risk ratings ranging from 1 to 6, where a higher rating represents higher risk. The Company differentiates its lending portfolios into loans sharing common risk characteristics for which expected credit loss is measured on a pool basis and loans not sharing common risk characteristics for which credit loss is measured individually.

The below are descriptions of the credit quality indicators:

Excellent – Excellent rated loans are prime quality loans covered by highly liquid collateral with generous margins or supported by superior current financial conditions reflecting substantial net worth, relative to total credit extended, and based on assets of a stable and non-speculative nature whose values can be readily verified. Identified repayment source or cash flow is abundant and assured. Loans are secured with cash, cash equivalents, or collateral with very low loan to values. The borrower would qualify for unsecured debt and guarantors provide excellent secondary support to the relationship. The borrower has a long-term relationship with the Company, maintains high deposit balances and has an established payment history with the Company and an established business in an established industry.

Good – Good rated loans are adequately secured by readily marketable collateral or good financial condition characterized by liquidity, flexibility and sound net worth. Loans are supported by sound primary and secondary payment sources and timely and accurate financial information. The relationship is not quite as strong as a borrower that is assigned an excellent rating but still has a very strong liquidity position, low leverage, and track record of strong performance. These loans have a strong collateral position with limited risk to bank capital. The collateral will not materially lose value in a distressed liquidation. Guarantors provide additional secondary support to mitigate possible bank losses. The borrower has a long-term relationship with the Company with an established track record of payments; loans with shorter remaining loan amortization; deposit

balances are consistent; loan payments could be made from cash reserves in the interim period; and source of income is coming from a stable industry.

Satisfactory – Satisfactory rated loans are loans to borrowers of average financial means not especially vulnerable to changes in economic or other circumstances, where the major support for the extension is sufficient collateral of a marketable nature, and the primary source of repayment is seen to be clear and adequate. The borrower's financial performance is consistent, ratios and trends are positive and the primary repayment source can clearly be identified and supported with acceptable financial information. The loan relationship could be vulnerable to changes in economic or industry conditions but have the ability to absorb unexpected issues. The loan collateral coverage is considered acceptable and guarantors can provide financial support but net worth might not be as liquid as a 1 or 2 rated relationship. The borrower has an established relationship with the Company. The relationship is making timely loan payments, any operating line is revolving and deposit balances are positive with limited to no overdrafts. Management and industry is considered stable.

Monitor – Monitor rated loans are identified by management as warranting special attention for a variety of reasons that may bear on ultimate collectability. This may be due to adverse trends, a particular industry, loan structure, or repayment that is dependent on projections, or a one-time occurrence. The relationship liquidity levels are minimal and the borrower's leverage position is brought into question. The primary repayment source is showing signs of being stressed or is not proven. If the borrower performs as planned, the loan will be repaid. The collateral coverage is still considered acceptable but there might be some concern with the type of real estate securing the debt or highly dependent on chattel assets. Some loans may be better secured than others. Guarantors still provide some support but there is not an abundance of financial strength supporting the guaranty. A monitor credit may be appropriate when the borrower is experiencing rapid growth which is impacting liquidity levels and increasing debt levels. Other attributes to consider would include if the business is a start-up or newly acquired, if the relationship has significant financing relationships with other financial institutions, the quality of financial information being received, management depth of the company, and changes to the business model. The track history with the Company has some deficiencies such as slow payments or some overdrafts.

Special Mention – Special mention rated loans are supported by a marginal payment capacity and are marginally protected by collateral. There are identified weaknesses that if not monitored and corrected may adversely affect the Company's credit position. A special mention credit would typically have a weakness in one of the general categories (cash flow, collateral position or payment history) but not in all categories. Potential indicators of a special mention would include past due payments, overdrafts, management issues, poor financial performance, industry issues, or the need for additional short-term borrowing. The ability to continue to make payments is in question; there are "red flags" such as past due payments, non-revolving credit lines, overdrafts, and the inability to sell assets. The borrower is experiencing delinquent taxes, legal issues, etc., obtaining financial information has become a challenge, collateral coverage is marginal at best, and the value and condition could be brought into question. Collateral document deficiencies have been noted and if not addressed, could become material. Guarantors provide minimal support for this relationship. The credit may include an action plan or follow up established in the asset quality process. There is a change in the borrower's communication pattern. Industry issues may be impacting the relationship. Adverse credit scores or history of payment deficiencies could be noted.

Substandard – Substandard loans are not adequately supported by the paying capacity of the borrower and may be inadequately collateralized. These loans have a well-defined weakness or weaknesses. Full repayment of the loan(s) according to the original terms and conditions is in question or not expected. For these loans, it is more probable than not that the Company could sustain some loss if the deficiency(ies) is not corrected. There are identified shortfalls in the primary repayment source such as carry over debt, past due payments, and overdrafts. Obtaining quality and timely financial information is a weakness. The loan is under secured with exposure that could impact the Company's capital. It appears the liquidation of collateral has become the repayment source. The collateral may be difficult to foreclose or have little to no value. Collateral documentation deficiencies have been noted during the review process. Guarantor(s) provide minimal to no support of the relationship. The borrower's communication with the Company continues to decrease and the borrower is not addressing the situation. There is some concern about the borrower's ability and willingness to repay the loans. Problems may be the result of external issues such as economic or industry related issues.

The following tables present total loans by risk categories and gross charge-offs by year of origination as of September 30, 2025 (amounts in thousands):

Loans 90 days or more past due that are still accruing interest decreased $0.83 million from December 31, 2024 to September 30, 2025. As of September 30, 2025, there were 2 accruing loans past due 90 days or more with an average loan balance of $0.02 million. There were 5 accruing loans past due 90 days or more as of December 31, 2024 with an average loan balance of $0.17 million. The accruing loans past due 90 days or more balances are believed to be adequately collateralized and the Company expects to collect all principal and interest as contractually due under these loans. There was no interest income recognized on nonaccrual loans for the nine months ended September 30, 2025 and year ended December 31, 2024.

The allowance for credit losses incorporates an estimate of lifetime expected credit losses and is recorded on each asset upon asset origination or acquisition. The starting point for the estimate of the allowance for credit losses is historical loss information, which includes losses from modifications of receivables to borrowers experiencing financial difficulty. An assessment of whether a borrower is experiencing financial difficulty is made on the date of a modification.

Because the effect of most modifications made to borrowers experiencing financial difficulty is already included in the allowance for credit losses because of the measurement methodologies used to estimate the allowance, a change to the allowance for credit losses is generally not recorded upon modification.

In some cases, the Company will modify a certain loan by providing multiple types of concessions. Typically, one type of concession, such as a term extension, is granted initially. If the borrower continues to experience financial difficulty, another concession, such as principal forgiveness, may be granted.

Upon the Company's determination that a modified loan (or portion of a loan) has subsequently been deemed uncollectible, the loan (or a portion of the loan) is written off. Therefore, the amortized cost basis of the loan is reduced by the uncollectible amount and the allowance for credit losses is adjusted by the same amount.

There were no financing receivables that had a payment default during the period and were modified in the 12 months before default to borrowers experiencing financial difficulty as of September 30, 2025 and for the nine months ending September 30, 2024.

The Company closely monitors the performance of the loans that are modified to borrowers experiencing financial difficulty to understand the effectiveness of its modification efforts. The following table depicts the performance of loans that have been modified in the last 12 months (numbers in thousands):

The changes in the ACL in 2025 compared to December 31, 2024 is the result of the following factors: changes in the economic factors used, specifically management's Iowa unemployment forecast, resulted in increases to the ACL with Iowa unemployment increasing throughout the third quarter; increase in loan volume which resulted in an increase; changes in prepayment and curtailment rates resulting in an increase; no change in the individually analyzed loans reserve; changes in qualitative factors determined necessary by management which resulted in an increase.

The extent to which collateral secures collateral-dependent loans is provided in the previous individually analyzed loans table and changes in the extent to which collateral secures its collateral-dependent loans are described below. Collateral-dependent loans decreased $5.23 million from December 31, 2024 to September 30, 2025. Collateral-dependent loans include any loan that has been placed on nonaccrual status, accruing loans past due 90 days or more, and loans made to borrowers with financial difficulties. Collateral-dependent loans also include loans that, based on management's evaluation of current information and events, the Company expects to be unable to collect in full according to the contractual terms of the original loan agreement. Collateral-dependent loans were 0.79% of loans held for investment as of September 30, 2025 and 0.97% as of December 31, 2024. The decrease in collateral-dependent loans is due to a decrease in loans with a specific reserve of $0.19 million, a decrease in nonaccrual loans of $5.31 million and a decrease in 90 days or more accruing loans of $0.83 million from December 31, 2024 to September 30, 2025. There were no significant changes noted in the extent to which collateral secures collateral-dependent loans.

The Company regularly reviews a substantial portion of the loans in the portfolio and assesses whether the loans share common risk characteristics for which expected credit loss is measured on a pool basis or if the loans do not share common risk characteristics and therefore expected credit loss is measured on an individual loan basis. If the loans are assessed for credit losses on an individual basis, the Company determines if a specific allowance is appropriate. In addition, the Company's management also reviews and, where determined necessary, provides allowances for particular loans based upon (1) reviews of specific borrowers and (2) management's assessment of areas that management considers are of higher credit risk, including loans that have been restructured or modified to a borrower experiencing financial difficulties. Loans that are determined not to be collateral-dependent and for which there are no specific allowances are classified into one or more risk categories and expected credit loss is measured on a pool basis. See Note 1 for further discussion of the allowance for credit losses for loans held for investment.

Specific allowances for credit losses on loans assessed individually are established if the loan balances exceed the net present value of the relevant future cash flows or the fair value of the relevant collateral based on updated appraisals and/or updated collateral analysis for the properties if the loan is collateral dependent. The Company may recognize a charge off or record a specific allowance related to an individually analyzed loan if there is a collateral shortfall or it is unlikely the borrower can make all principal and interest payments as contractually due.

For loans that are collateral-dependent, losses are evaluated based on the portion of a loan that exceeds the fair market value of the collateral. In general, this is the amount that the carrying value of the loan exceeds the related appraised value less estimated costs to sell the collateral. Generally, it is the Company's policy not to rely on appraisals that are older than one year prior to the date the credit loss is being measured. The most recent appraisal values may be adjusted if, in the Company's judgment, experience and other market data indicate that the property's value, use, condition, exit market or other variables affecting its value may have changed since the appraisal was performed. The charge off or loss adjustment supported by an appraisal is considered the minimum charge off. Any adjustments made to the appraised value are to provide an additional charge off or specific reserve based on the applicable facts and circumstances. In instances where there is an estimated decline in value, a specific reserve may be provided or a charge off taken pending confirmation of the amount of the loss from an updated appraisal. Upon receipt of the new appraisals, an additional specific reserve may be provided or charge off taken based on the appraised value of the collateral. On average, appraisals are obtained within one month of order.

**Note 6.Leases**

The Bank leases certain of its branch offices, parking facilities and certain equipment under operating leases. The leases have remaining lease terms of 2 years to 9 years, some of which include options to extend the leases for up to 5 years, and some of which include options to terminate the leases within 3 years. As the options are reasonably certain to be exercised, they are recognized as part of the right-of-use assets and lease liabilities.

For the three months ended September 30, 2025 and 2024 total operating lease expense was $X million and $X million respectively and for the nine months ended September 30, 2025 and 2024, total operating lease expense was $0.35 million and

$0.42 million respectively, and is included in occupancy expenses in the consolidated statements of income. Included in this for the nine months ended September 30, 2025 and 2024 were $0.33 million and $0.35 million, respectively, of operating lease costs, $0.01 million and $0.02 million, respectively, of short term lease costs, and $0.01 million and $0.05 million, respectively, of variable lease costs.

For the nine months ended September 30, 2025 and 2024, cash paid for amounts included in the measurement of operating lease liabilities was $0.33 million and $0.35 million, respectively.

As of September 30, 2025 and December 31, 2024, operating lease right-of-use assets included in other assets was $1.67 million and $1.87 million respectively. Operating lease liabilities included in other liabilities were $1.77 million and $1.97 million as of September 30, 2025 and December 31, 2024. As of September 30, 2025 and December 31, 2024, the weighted average remaining lease term for operating leases was 7.19 years and 7.75 years, respectively, and the weighted average discount rate for operating leases was 3.68% and 3.68%, respectively. Discount rates used were determined from FHLB borrowing rates for comparable terms.

<u>Fair value of financial instruments</u>: FASB ASC 820, *Fair Value Measurements and Disclosures* ("ASC 820") provides a single definition for fair value, a framework for measuring fair value and expanded disclosures concerning fair value. Fair value is

defined under ASC 820 as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date.

The Company determines the fair market value of its financial instruments based on the fair value hierarchy established in ASC 820. There are three levels of inputs that may be used to measure fair value as follows:

 Level 1 Quoted prices in active markets for identical assets or liabilities.

---

| | |
|:---|:---|
| Level 2 | Observable inputs other than quoted prices included within Level 1. Observable inputs include the quoted prices for similar assets or liabilities in markets that are not active and inputs other than quoted prices that are observable for the asset or liability. |

---

---

| | |
|:---|:---|
| Level 3 | Unobservable inputs supported by little or no market activity for financial instruments. Level 3 assets and liabilities include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation. |

---

It is the Company's policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. The Company is required to use observable inputs, to the extent available, in the fair value estimation process unless that data results from forced liquidations or distressed sales.

The following is a description of valuation methodologies used for assets and liabilities recorded at fair value.

<u>Investment securities available for sale</u>: Investment securities available for sale are recorded at fair value on a recurring basis. Fair value measurement is based upon quoted prices, if available. If a quoted price is not available, the fair value is obtained from benchmarking the security against similar securities. U.S. Treasury securities are considered Level 1 with the remaining securities considered Level 2.

The pricing for investment securities is obtained from an independent source. There are no Level 3 investment securities owned by the Company. The Company obtains an understanding of the independent source's valuation methodologies used to determine fair value by level of security. The Company validates assigned fair values on a sample basis using an additional third-party provider pricing service to determine if the fair value measurement is reasonable. Due to the nature of our investment portfolio, we do not expect significant and unusual fluctuations as fair value changes primarily relate to interest rate changes. No unusual fluctuations were identified during the nine months ended September 30, 2025. If a fluctuation requiring investigation was identified, the Company would research the change with the independent source or other available information.

<u>Individually analyzed loans under ASC 326 CECL</u>: See Note 1 for further discussion of individually analyzed loans under CECL.

A loan is considered to be non-performing when it is probable that all of the principal and interest due may not be collected according to its contractual terms. Generally, when a loan is considered non-performing, the amount of reserve is measured based on the fair value of the underlying collateral. The Company makes such measurements on all material loans deemed non-performing using the fair value of the collateral for collateral dependent loans or based on the present value of the estimated future cash flows of interest and principal discounted at the loans effective interest rate or the fair value of the loan if determinable. The fair value of collateral used by the Company is determined by obtaining an observable market price or by obtaining an appraised value from an independent, licensed or certified appraiser, using observable market data. This data includes information such as selling price of similar properties and capitalization rates of similar properties sold within the market, expected future cash flows or earnings of the subject property based on current market expectations, and other relevant factors. All appraised values are adjusted for market-related trends based on the Company's experience in sales and other appraisals of similar property types as well as estimated selling costs. These loans are considered Level 3 as the instruments used to determine fair market value require significant management judgment and estimation.

<u>Foreclosed assets</u>: The Company does not record foreclosed assets at fair value on a recurring basis. Foreclosed assets consist mainly of other real estate owned but may include other types of assets repossessed by the Company. Foreclosed assets are adjusted to the lower of carrying value or fair value less the cost of disposal. Fair value is generally based upon independent market prices or appraised values of the collateral, and may include a marketability discount as deemed necessary by

**(Unaudited)**

management based on its experience with similar types of real estate. The value of foreclosed assets is evaluated periodically as a nonrecurring fair value adjustment. Foreclosed assets are classified as Level 3.

<u>Off-balance sheet instruments</u>: Fair values for outstanding letters of credit are based on fees currently charged to enter into similar agreements, taking into account the remaining terms of the agreements and the counterparties' credit standing. The fair value of the outstanding letters of credit is not significant. Unfunded loan commitments are not valued since the loans are generally priced at market at the time of funding (Level 2).

<u>Interest rate swap agreements</u>: The fair value is estimated using forward-looking interest rate curves and is calculated using discounted cash flows that are observable or that can be corroborated by observable market data (Level 2).

*Assets and Liabilities Recorded at Fair Value on a Nonrecurring Basis*

The Company is required to measure certain assets at fair value on a nonrecurring basis in accordance with GAAP. These adjustments to fair value usually result from application of lower-of-cost-or-market accounting or write-downs of individual assets. The valuation methodologies used to measure these fair value adjustments are described above. The following tables present the Company's assets that are measured at fair value on a nonrecurring basis.

**Note 8.Stock Repurchase Program**

On July 26, 2005, the Company's Board of Directors authorized a program to repurchase up to a total of 1,500,000 shares of the Company's common stock (the "2005 Stock Repurchase Program"). On August 9, 2022, the Company's Board of Directors authorized the expansion of the 2005 Stock Repurchase Program to allow an additional 750,000 shares for repurchase and the continuation through December 31, 2027. The Company expects the purchases pursuant to the 2005 Stock Repurchase Program to be made from time to time in private transactions at a price equal to the most recent quarterly independent appraisal of the shares of the Company's common stock and with the Board reviewing the overall results of the 2005 Stock Repurchase Program on a quarterly basis. All purchases made pursuant to the 2005 Stock Repurchase Program since its inception have been made on that basis. The amount and timing of stock repurchases will be based on various factors, such as the Board's assessment of the Company's capital structure and liquidity, the amount of interest shown by shareholders in selling shares of stock to the Company at their appraised value, and applicable regulatory, legal and accounting factors. The Company has purchased 1,962,471 shares of its common stock in privately negotiated transactions from August 1, 2005 through September 30, 2025. Of these 1,962,471 shares, 46,055 shares were purchased during the quarter ended September 30, 2025, at an average price per share of $78.17.

**Note 9. Commitments and Contingencies**

<u>Concentrations of credit risk</u>: The Company's loans, commitments to extend credit, unused lines of credit and outstanding letters of credit have been granted to customers within the Company's market area. Investments in securities issued by state and political subdivisions within the state of Iowa totaled approximately $155.93 million. The concentrations of credit by type of loan are set forth in Note 5 to the Consolidated Financial Statements. Outstanding letters of credit were granted primarily to commercial borrowers. Although the Company has a diversified loan portfolio, a substantial portion of its debtors' ability to honor their contracts is dependent upon the economic conditions in Johnson, Linn, Washington and Iowa Counties, Iowa.

<u>Contingencies</u>: In the normal course of business, the Company and its subsidiaries are subject to pending and threatened legal actions, some of which seek substantial relief or damages. While the ultimate outcome of such legal proceedings cannot be predicted with certainty, after reviewing pending and threatened litigation with counsel, management believes at this time that the outcome of such litigation will not have a material adverse effect on the Company's business, financial conditions, or results of operations.

<u>Financial instruments with off-balance sheet risk</u>: The Company is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit, credit card participations and standby letters of credit. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in the consolidated balance sheets.

The Company's exposure to credit loss in the event of nonperformance by the other party to the financial instrument for commitments to extend credit, credit card participations and standby letters of credit is represented by the contractual amount of those instruments. The Company uses the same credit policies in making commitments and conditional obligations as it does for on-balance sheet instruments. A summary of the Company's commitments at September 30, 2025 and December 31, 2024 is as follows:

---

| | | |
|:---|:---|:---|
| | **September 30, 2025** | **December 31, 2024** |

**Note 10.Income Taxes**

Federal income tax expense for the nine months ended September 30, 2025 and 2024 was computed using the consolidated effective federal tax rate. The Company also recognized income tax expense pertaining to state franchise taxes payable individually by the subsidiary bank. The Company files a consolidated tax return for federal purposes and separate tax returns for State of Iowa purposes. The tax years ended December 31, 2024, 2023, and 2022 remain subject to examination by the Internal Revenue Service. For state tax purposes, the tax years ended December 31, 2024, 2023, and 2022 remain open for examination. There were no material unrecognized tax benefits at September 30, 2025 and December 31, 2024 and therefore no interest or penalties on unrecognized tax benefits has been recorded. As of September 30, 2025, the Company does not anticipate any significant increase in unrecognized tax benefits during the twelve-month period ending September 30, 2026. Income taxes as a percentage of income before taxes were 20.10% for the nine months ended September 30, 2025 and 20.92% for the same period in 2024.

**Note 11.Derivative Financial Instruments**

In the normal course of business, the Bank may use derivative financial instruments to manage its interest rate risk. These instruments carry varying degrees of credit, interest rate and market or liquidity risks. Derivative instruments are recognized as

either assets or liabilities in the accompanying consolidated financial statements and are measured at fair value. The Bank's objectives are to add stability to its net interest margin and to manage its exposure to movements in interest rates. The contract or notional amount of a derivative is used to determine, along with the other terms of the derivative, the amount to be exchanged between the counterparties. The Bank is exposed to credit risk in the event of nonperformance by counterparties to financial instruments. The Bank minimizes this risk by entering into derivative contracts with large, stable financial institutions. The Bank has not experienced any losses from nonperformance by counterparties. The Bank monitors counterparty risk in accordance with the provisions of ASC 815. In addition, the Bank's interest rate-related derivative instruments contain language outlining collateral pledging requirements for each counterparty. Collateral must be posted when the market value exceeds certain threshold limits which are determined by credit ratings of each counterparty. The Bank entered into one interest rate swap agreement in November 2023 and was required to pledge a US Treasury in the amount of none and $250 thousand of collateral as of September 30, 2025 and December 31, 2024, respectively, due to the agreement expiring May 15, 2025.

Cash Flow Hedges: The Bank executed one forward-starting interest rate swap transaction on November 28, 2023. The interest rate swap transaction had an effective date of December 15, 2023, and an expiration date of May 15, 2025, effectively converting variable rate debt to fixed rate debt. For accounting purposes, this swap transaction was designated as a cash flow hedge of the changes in cash flows attributable to changes in the effective federal funds rate, the benchmark interest rate being hedged, associated with the interest payments made on an amount of the Bank's debt principal equal to the then-outstanding swap notional amount. The underlying principal balance was matched to future advances related to a large customer construction project, however, the FHLB advances remained equal to the notional amount of the swap making it probable that sufficient effective federal funds rate based interest payments would exist through the maturity date of the swap.

The table below identifies the balance sheet category and fair value of the Bank's derivative instrument designated as a cash flow hedge as of September 30, 2025 and December 31, 2024:

**Note 13. &nbsp;&nbsp;&nbsp;&nbsp;Segment Reporting**

The Company conducts operations through one reportable segment which is determined by the Senior Executive Committee, which is designated the chief operating decision maker, based upon information provided about the Company's products and services offered, primarily banking operations. The Executive Committee consists of the President/Chief Executive Officer and the Chief Financial Officer. The segment is also distinguished by the level of information provided to the Executive Committee, who uses such information to review performance of various components of the business (such as branches), which are then aggregated if operating performance, products/services, and customers are similar. The Executive Committee will evaluate the financial performance of the Company's business components such as by evaluating revenue streams, significant expenses, and budget to actual results in assessing the Company's segment and in the determination of allocating resources. The Executive Committee uses revenue streams to evaluate product pricing and significant expenses to assess performance and evaluate return on assets. The Executive Committee uses consolidated net income to benchmark the Company against its competitors. The benchmarking analysis coupled with monitoring of budget to actual results are used in assessing performance and in establishing compensation. Loans, investments, and deposits provide the revenues in the banking operation. Interest expense, credit loss expense, and payroll provide the significant expenses in the banking operation. All operations are domestic.

Accounting policies for segments are the same as those described in Note 1. Segment performance is evaluated using consolidated net income from the consolidated statements of income. Significant income and expenses are included on the consolidated statements of income. These include interest income, interest expense, net interest income, and noninterest income. Significant expenses used in evaluating Company performance are credit loss expense and salaries and employee benefits which are included on the consolidated statements of income.

&nbsp;&nbsp;&nbsp;&nbsp;• The financial strength of the counterparties with which the Company or the Company's customers do business and as to which the Company has investment or financial exposure.

&nbsp;&nbsp;&nbsp;&nbsp;• The credit quality and credit agency ratings of the securities in the Company's investment securities portfolio, a deterioration or downgrade of which could lead to recognition of an allowance for credit losses on the affected securities and the recognition of a credit loss.

&nbsp;&nbsp;&nbsp;&nbsp;• The effects of, and changes in, laws, regulations and policies affecting banking, securities, insurance and monetary and financial matters as well as any laws otherwise affecting the Company, including, but not limited to, potential changes in U.S. tax laws and regulations.

&nbsp;&nbsp;&nbsp;&nbsp;• The effects of changes in interest rates (including the effects of changes in the rate of prepayments of the Company's assets) and the policies of the Board of Governors of the Federal Reserve System.

&nbsp;&nbsp;&nbsp;&nbsp;• The ability of the Company to compete with other financial institutions as effectively as the Company currently intends due to increases in competitive pressures in the financial services sector.

&nbsp;&nbsp;&nbsp;&nbsp;• The ability of the Company to obtain new customers and to retain existing customers.

&nbsp;&nbsp;&nbsp;&nbsp;• The timely development and acceptance of products and services, including products and services offered through alternative electronic delivery channels.

&nbsp;&nbsp;&nbsp;&nbsp;• Technological changes implemented by the Company and by other parties, including third party vendors, which may be more difficult or more expensive than anticipated or which may have unforeseen consequences to the Company and its customers.

These risks and uncertainties should be considered in evaluating forward-looking statements, and undue reliance should not be placed on such statements. Additional information concerning the Company and its business, including other factors that could materially affect the Company's financial results, is included in the Company's filings with the Securities and Exchange Commission.

**Economic Environment** 

Economic data for the third quarter from the Midwest, as reported in the Federal Reserve System's "Beige Book," shows flat employment in the region over the most recently completed period, with slight decrease anticipated by employers operating in the region over the next 12 months, with the manufacturing sector continuing to experience the most difficulty in filling open positions. Prices rose modestly in the Midwest in late August and September, with a similar pace of growth anticipated over the next 12 months. The manufacturing sector in particular faces heightened uncertainty about both input costs and selling prices attributed primarily to uncertainties surrounding changing tariff policies. In the retail sector, retailers are trying to hold off passing tariff-related cost increases on to consumers for as long as possible, though several smaller retailers reported already raising prices because of tariffs. Despite this outlook, consumer spending increased modestly over the reporting period, continuing the growth from earlier in the year from consumers hoping to buy ahead of the increase in costs on higher ticket consumer goods anticipated for later in the year. Conversely, business spending declined slightly in late August and September, with many sectors anticipating hesitancy in capital purchases over the foreseeable future due to increased uncertainty surrounding tariffs and the economic outlook. On the agricultural front, income expectations from growers and other producers for 2025 have remained largely unchanged for the remainder of 2025. However, increased concerns about higher input costs for 2026 and lack of clarity on the economic outlook was negatively impacting capital investment.

Our credit administration continues to closely monitor and analyze the higher risk segments within the loan portfolio, tracking loan payment deferrals, customer liquidity and providing timely reports to senior management and the board of directors. Based on the Company's capital levels, prudent underwriting policies, loan concentration diversification and our geographic footprint, senior management is cautiously optimistic that the Company is positioned to continue managing the impact of the varied set of risks and uncertainties currently impacting the economy and remain adequately capitalized. However, the Company may be required to make additional credit loss provisions as warranted by the extremely fluid economic conditions and continued migration in the loan portfolio towards the special mention and substandard risk rating categories.

The Bank has an established formal loan origination policy. In general, the loan origination policy attempts to reduce the risk of credit loss to the Company by requiring, among other things, maintenance of minimum loan to value ratios, evidence of appropriate levels of insurance carried by borrowers and documentation of appropriate types and amounts of collateral and sources of expected payment. The collateral relied upon in the loan origination policy is generally the property being financed by the Company. The source of expected payment is generally the income produced from the property being financed. Personal guarantees are required of individuals owning or controlling at least 20% of the ownership of an entity. Limited or proportional guarantees may be accepted in circumstances if approved by the Company's Board of Directors. Financial information provided by the borrower is verified as considered necessary by reference to tax returns, or audited, reviewed or compiled financial statements. The Company does not originate subprime loans. In order to modify, restructure or otherwise change the terms of a loan, the Company's policy is to evaluate each borrower situation individually. Modifications, restructures, extensions and other changes are done to improve the Company's position and to protect the Company's capital. If a borrower is not current with its payments, any additional loans to such borrowers are evaluated on an individual borrower basis.

The Company has not experienced any significant time lapses in recognizing the required provisions for collateral dependent loans, nor has the Company delayed appropriate charge offs. When an updated appraisal value has been obtained, the Company has used the appraisal amount in determining the appropriate charge off or required reserve. The Company also evaluates any changes in the financial condition of the borrower and guarantors (if applicable), economic conditions, and the Company's loss experience with the type of property in question. Any information utilized in addition to the appraisal is intended to identify additional charge offs or provisions, not to override the appraised value.

In accordance with Staff Accounting Bulletin No. 102, Selected Loan Loss Allowance Methodology and Documentation Issues, and Staff Accounting Bulletin No. 119, which aligns the staff's guidance with FASB ASC Topic 326, or CECL, the Company determines and assigns ratings to loans using factors that include the following: an assessment of the financial condition of the borrower; a realistic determination of the value and adequacy of underlying collateral; the condition of the local economy and the condition of the specific industry of the borrower; an analysis of the levels and trends of loan categories; and a review of delinquent and classified loans.

Through the credit risk rating process, loans are reviewed to determine if they are performing in accordance with the original contractual terms. If the borrower has failed to comply with the original contractual terms, further action may be required by the Company, including a downgrade in the credit risk rating, movement to non-accrual status, a charge-off or the establishment of a specific reserve. In the event a collateral shortfall is identified during the credit review process, the Company will work with the borrower for a principal reduction and/or a pledge of additional collateral and/or additional guarantees. In the event that these options are not available, the loan may be subject to a downgrade of the credit risk rating. If the Company determines a loan amount or portion thereof, is uncollectible, the loan's credit risk rating may be downgraded and the uncollectible amount charged-off or recorded as a specific allowance for losses. The Company's credit and legal departments undertake a thorough and ongoing analysis to determine if additional specific reserves and/or charge-offs are appropriate and to begin a workout plan for the loan to minimize actual losses.

The following table presents the allowance for credit losses as of September 30, 2025 and December 31, 2024 by loan category, the percentage of the allowance for each category to the total allowance, and the percentage of all loans in each category to total loans:

The allowance for credit losses (ACL) totaled $59.10 million at September 30, 2025 compared to the allowance of $50.94 million at December 31, 2024. The percentage of the allowance to outstanding loans was 1.66% and 1.48% at September 30, 2025 and December 31, 2024, respectively. The allowance was based on management's consideration of a number of factors, including composition of the loan portfolio, loans with higher credit risks and the overall amount of loans outstanding. The changes in the ACL in 2025 compared to December 31, 2024 is the result of the following factors: changes in the economic factors used, specifically management's Iowa unemployment forecast which resulted in an increase, increase in loan volume which resulted in an increase; changes in prepayment and curtailment rates resulting in an increase; no change in the

individually analyzed loans reserve; changes in qualitative factors determined necessary by management which resulted in an increase, and an increase due to net charge-offs, primarily in the first and third quarters, leading to higher loss rates.

The adequacy of the allowance is reviewed quarterly and adjusted as appropriate after consideration has been given to the impact of economic conditions on the borrowers' ability to repay, loan collateral values, past collection experience, the risk characteristics of the loan portfolio and such other factors that deserve current recognition. The growth of the loan portfolio and the trends in nonperforming loans are significant elements in the determination of the allowance for credit losses. Quantitative factors include the Company's historical loss experience, which is then adjusted for levels and trends in past due, levels and trends in charged-off and recovered loans, trends in volume growth, trends in nonperforming loans, trends in modified loans, local economic trends and conditions, and industry and other conditions.

Management has determined that the allowance for credit losses was adequate at September 30, 2025, and that the loan portfolio is diversified and secured, without undue concentration in any specific risk area. This process involves a high degree of management judgment; however, the allowance for credit losses is based on a comprehensive, well documented, and consistently applied analysis of the Company's loan portfolio. This analysis takes into consideration all available information existing as of the financial statement date, including environmental factors such as economic, industry, geographical and political factors. The relative level of allowance for credit losses is reviewed and compared to industry data. This review encompasses levels of total collateral-dependent loans, portfolio mix, portfolio concentrations, current geographic risks and overall levels of net charge-offs.

Investment securities available for sale held by the Company increased by $18.63 million from December 31, 2024 to September 30, 2025. The fair value of securities available for sale was $12.06 million less than the amortized cost of such securities as of September 30, 2025. At December 31, 2024, the fair value of the securities available for sale was $35.72 million less than the amortized cost of such securities.

Deposits increased $32.13 million in the first nine months of 2025. In the opinion of the Company's management, the Company continues to have sufficient liquidity resources available to fund expected additional loan growth.

Brokered deposits are included in total deposits and totaled $35.07 million as of September 30, 2025 with an average rate of 4.51%. Brokered deposits were $34.75 million as of December 31, 2024 with an average interest rate of 4.51%. As of September 30, 2025 and December 31, 2024, brokered deposits were 1.04% and 1.04% of total deposits, respectively.

There were $76.58 million and $127.05 million of Federal Home Loan Bank (FHLB) borrowings as of September 30, 2025 and December 31, 2024, respectively. There were $588.74 million of Federal Funds purchased as of September 30, 2025 and $437.64 million as of December 31, 2024. Total funds purchased from the Bank Term Funding program was none as of September 30, 2025, and $109.00 million as of December 31, 2024. It is expected that the FHLB and Federal Funds funding sources will be considered in the future if loan growth exceeds core deposit increases and the interest rates on funds borrowed from the FHLB and Federal Funds are favorable compared to other funding alternatives.

**Dividends and Equity**

In January 2025, Hills Bancorporation paid a dividend of $10.32 million or $1.15 per share. The dividend paid in January 2024 was $1.10 per share. After payment of the dividend and the adjustment for accumulated other comprehensive income (loss), stockholders' equity as of September 30, 2025 totaled $531.23 million.

The Company elected to use the Community Bank Leverage Ratio (CBLR) framework as provided for in the Economic Growth, Regulatory Relief and Consumer Protection Act. Under the CBLR framework, the Company is required to maintain a CBLR of greater than 9%, as measured by dividing the Bank's Tier 1 capital by its average total consolidated assets.

**<u>Discussion of operations for the nine months ended September 30, 2025 and 2024</u>**

**Net Income Overview**

Total net income was $45.99 million in 2025 and $36.58 million in the comparable period in 2024, an increase of $9.41 million or 25.72%. The change in net income in 2025 from the first nine months of 2024 was primarily the result of the following:

• Net interest income before credit loss expense increased by $24.62 million or 28.93%.

• For the nine months ended September 30, 2025, credit loss expense was $10.98 million. This represents an increase in expense of $8.36 million from the credit loss expense of $2.62 million for the nine months ended September 30, 2024.

• Noninterest income decreased by $2.05 million, or 8.92%.

• Noninterest expenses increased by $2.91 million, or 4.92%.

For the nine month period ended September 30, 2025 and September 30, 2024 basic earnings per share was $5.17 and $4.03, respectively. Diluted earnings per share was $5.16 for the nine months ended September 30, 2025 compared to $4.03 for the same period in 2024.

The Company's net income for the period was driven primarily by three primary factors. The first factor affecting the Company's net income is the interaction between changes in net interest margin and changes in average volumes of the Company's earnings assets. Net interest income of $109.71 million for the first nine months of 2025 was derived from the Company's $4.444 billion of average earning assets during that period and its tax-equivalent net interest margin of 3.41%. Average earning assets in the nine months ended September 30, 2024 were $4.257 billion and the tax-equivalent net interest margin was 2.74%. Net interest income for the Company increased primarily as a result of increased interest income from higher interest rates on real estate and commercial loans and investments as well as higher volume of investments. Also, overall interest expense was slightly lower than the same period in 2024 due to favorable rate variances. The Company expects net interest margin compression to impact earnings for the foreseeable future due to competition for loans and deposits. The Company believes growth in net interest income will be contingent on the growth of the Company's earning assets, increasing yield on loans and the ongoing interest rate stance of the Federal Reserve Board.

The second factor is credit loss expense. The majority of the Company's interest-earning assets are in loans outstanding, which amounted to more than $3.501 billion at September 30, 2025. Credit loss expense was $10.98 million in 2025 compared to $2.62 million in 2024. The increase in expense when compared to the same period in 2024 is primarily attributable to the following: changes in the economic factors used, specifically management's Iowa unemployment forecast which resulted in an increase, increase in loan volume which resulted in an increase; changes in prepayment and curtailment rates resulting in an increase; no change in the individually analyzed loans reserve; changes in qualitative factors determined necessary by management which resulted in an increase, and an increase due to net charge-offs, primarily in the first and third quarters, leading to higher loss rates.The Company believes that credit loss expense is expected to be dependent on the Company's loan growth, local economic conditions and asset quality.

The third factor affecting the Company's net income is noninterest income, primarily the increase in trust fees and other noninterest income. Trust fees were $12.54 million and $11.23 million for the nine months ended September 30, 2025 and 2024, respectively, an increase of 11.71%. This is primarily driven by the increase in assets under management of $0.270 billion from $2.955 billion as of September 30, 2024 to $3.225 billion as of September 30, 2025 with increased market activity and performance compared to the prior year period. Additionally, the Company recognized $4.29 million and $0 of loss on sale of investment securities for the nine months ended September 30, 2025 and 2024, respectively. Other noninterest income was $1.69 million and $0.36 million for the nine months ended September 30, 2025 and 2024, respectively, an increase of 374.44%, primarily due to incentive and marketing bonuses from the VISA payment network growth agreement.

**Net Interest Income**

Net interest income is the excess of the interest and fees earned on interest-earning assets over the interest expense of the interest-bearing liabilities. Net interest income on a tax equivalent basis increased $25.70 million for the nine months ended September 30, 2025 compared to the comparable period in 2024. The increase was primarily as a result of increased interest income from higher interest rates on real estate and commercial loans and investments as well as higher volume of loans and investments. Also, overall interest expense was slightly lower than the same period in 2024 due to favorable rate variances. The net interest margin for the first nine months of 2025 was 3.41% compared to 2.74% in 2024 for the same period. The measure is shown on a tax-equivalent basis using a tax rate of 21% to make the interest earned on taxable and non-taxable assets more comparable. The change in average balances and average rates between periods and the effect on the net interest income on a tax equivalent basis for the nine months ended in 2025 compared to the comparable period in 2024 are shown in the following table:

**HILLS BANCORPORATION**

In pricing loans and deposits, the Company considers the U.S. Treasury indexes as benchmarks in determining interest rates. The Federal Open Market Committee met six times during the first nine months of 2025. The federal funds target rate decreased to 4.25% as of September 30, 2025 from 5.00% as of the same period in 2024. Interest rates on loans are generally affected by the federal funds target rate since interest rates for the U.S. Treasury market normally increase or decrease when the Federal Reserve Board raises or lowers the federal funds rate. As of September 30, 2025, the rate indexes for the one, three and five year indexes were 3.65%, 3.63% and 3.74%, respectively. The one year index decreased 6.41% from 3.90% at September 30, 2024, the three year index increased 4.01% and the five year index increased 6.86%. The three year index was 3.49% and the five year index was 3.50% at September 30, 2024.

**Credit Loss Expense**

Credit loss expense was $10.98 million for the nine months ended September 30, 2025 compared to $2.62 million in 2024, an increase of expense of $8.36 million. Credit loss expense is the amount necessary to adjust the allowance for credit losses to the level considered by management to appropriately account for the estimated current expected credit losses within the Company's loan portfolio.

A significant component of the Company's approach to estimating expected credit losses are economic forecasts such as Iowa unemployment and National real gross domestic product (National GDP). For the allowance for credit losses as of September 30, 2025, the key loss drivers were Iowa unemployment and National GDP. The increase in expense when compared to the same period in 2024 is primarily attributable to the following: changes in the economic factors used, specifically management's Iowa unemployment forecast which resulted in an increase, increase in loan volume which resulted in an increase; changes in prepayment and curtailment rates resulting in an increase; no change in the individually analyzed loans reserve; changes in qualitative factors determined necessary by management which resulted in an increase, and an increase due to net charge-offs, primarily in the first and third quarters, leading to higher loss rates.The Company believes that credit loss expense is expected to be dependent on the Company's loan growth, local economic conditions and asset quality.

The allowance for credit losses balance is impacted by charge-offs, net of recoveries, for the periods presented. For the nine months ended September 30, 2025 and 2024, recoveries were $2.63 million and $2.63 million, respectively; and charge-offs were $4.51 million in 2025 and $5.20 million in 2024. The allowance for credit losses totaled $59.10 million at September 30, 2025 compared to $50.94 million as of December 31, 2024. The allowance represented 1.66% and 1.48% of loans held for investment at September 30, 2025 and December 31, 2024.

**Liquidity**

The Company actively monitors and manages its liquidity position with the objective of maintaining sufficient cash flows to fund operations, meet commitments, take advantage of market opportunities and provide a margin against unforeseeable liquidity needs. Federal funds sold and investment securities available for sale are readily marketable assets. Maturities of all investment securities are managed to meet the Company's normal liquidity needs, to respond to market changes or to adjust the Company's interest rate risk position. Investment securities available for sale comprised 20.69% of the Company's total assets at September 30, 2025 compared to 20.58% at December 31, 2024. As of September 30, 2025, investment securities with a carrying value of $137.13 million were pledged to collateralize public and trust deposits and other borrowings. As of December 31, 2024, investment securities with a carrying value of $250.65 million were pledged.

The Company has historically maintained a stable deposit base and a relatively low level of large deposits, which has mitigated the volatility in the Company's liquidity position. Deposit inflows and outflows can vary widely based on prevailing market interest rates, competition, economic conditions, our business customers' liquidity needs and by recent developments in the financial services industry. Uninsured deposits as of September 30, 2025 and December 31, 2024 were approximately $807.20 million and $719.62 million, respectively, which comprised 23.89% and 21.51% of total deposits.

As of September 30, 2025, the Company had $76.58 million of outstanding borrowings from the Federal Home Loan Bank ("FHLB") of Des Moines compared to $127.05 million as of December 31, 2024. The Company had $588.74 million Fed Funds purchased as of September 30, 2025 compared to $546.64 million of Fed Funds purchased as of December 31, 2024. The Company had no Bank Term Funding Program borrowings as of September 30, 2025 and $109.00 million as of December 31, 2024. These borrowings are used as a means of providing both long and short-term funding for certain assets and for managing interest rate risk.

The Company had additional borrowing capacity available from the FHLB of approximately $974.18 million at September 30, 2025. As additional sources of liquidity, the Company has the ability to borrow up to $100.00 million from the Federal Reserve Bank of Chicago, and has lines of credit with three banks totaling $175.00 million. The borrowings under these credit lines would be secured by the Company's investment securities. In addition, the Company has the option of issuing short-, medium-, and long-term debt, should the Company decide to do so. The combination of high levels of potentially liquid assets, low dependence on volatile liabilities, positive cash flows from operations, and both additional borrowing and brokered deposits capacity provided sources of liquidity for the Company which management considered sufficient at September 30, 2025.

**Contractual Obligations**

There have been no material changes with regard to contractual obligations disclosed in the Company's Form 10-K for the year ended December 31, 2024.

| **Item 3.** | **Quantitative and Qualitative Disclosures about Market Risk** |

---

The Company's primary market risk exposure is to changes in interest rates. Interest rate risk is the risk to current or anticipated earnings or capital arising from movements in interest rates. Interest rate risk arises from repricing risk, basis risk, yield curve risk and options risk. Repricing risk is the difference between the timing of rate changes and the timing of cash flows. Basis risk is the difference from changing rate relationships among different yield curves affecting Bank activities. Yield curve risk is the difference from changing rate relationships across the spectrum of maturities. Option risk is the difference resulting from interest-related options embedded in Company products. The Company's primary source of interest rate risk exposure arises from repricing risk. To measure this risk the Company uses a static gap measurement system that identifies the repricing gaps across the full maturity spectrum of the Company's assets and liabilities and an earnings simulation approach. The gap schedule is known as the interest rate sensitivity report. The report reflects the repricing characteristics of the Company's assets and liabilities. The report details the calculation of the gap ratio. This ratio indicates the amount of interest-earning assets repricing within a given period in comparison to the amount of interest-bearing liabilities repricing within the same period of time. A gap ratio of 1.0 indicates a matched position, in which case the effect on net interest income due to interest rate movements will be minimal. A gap ratio of less than 1.0 indicates that more liabilities than assets reprice within the time period, and a ratio greater than 1.0 indicates that more assets reprice than liabilities.

The Company's asset/liability management, or its management of interest rate risk, is focused primarily on evaluating and managing net interest income given various risk criteria. Factors beyond the Company's control, such as market interest rates and competition, may also have an impact on the Company's interest income and interest expense. In the absence of other factors, the Company's overall yield on interest-earning assets will increase as will its cost of funds on its interest-bearing liabilities when market interest rates increase over an extended period of time. Inversely, the Company's yields and cost of funds will decrease when market rates decline. The Company is able to manage these swings to some extent by attempting to control the maturity or rate adjustments of its interest-earning assets and interest-bearing liabilities over given periods of time.

The Company maintains an Asset/Liability Committee, which meets at least quarterly to review the interest rate sensitivity position and to review and develop various strategies for managing interest rate risk within the context of the following factors: 1) capital adequacy, 2) asset/liability mix, 3) economic outlook, 4) market characteristics and 5) the interest rate forecast. In addition, the Company uses a simulation model to review various assumptions relating to interest rate movement. The Company engages a third party that utilizes a modeling program to measure the Company's exposure to potential interest rate changes. For various assumed hypothetical changes in market interest rates, this analysis measures the estimated change in net interest income. The simulations allow for ongoing assessment of interest rate sensitivity and can include the impact of potential new business strategies. The modeled scenarios begin with a base case in which rates are unchanged and include parallel and nonparallel rate shocks. The results of these shocks are measured in two forms: first, the impact on the net interest margin and earnings over one and two year time frames; and second, the impact on the market value of equity. The results of the simulation are compared against approved policy limits. The model attempts to limit rate risk even if it appears the Company's asset and liability maturities are perfectly matched and a favorable interest margin is present. The Company's policy is to generally maintain a balance between profitability and interest rate risk.

In order to minimize the potential effects of adverse material and prolonged increases or decreases in market interest rates on the Company's operations, management has implemented an asset/liability program designed to mitigate the Company's interest rate sensitivity. The program emphasizes the origination of adjustable rate loans, which are held in the portfolio, the investment of excess cash in short or intermediate term interest-earning assets, and the solicitation of transaction deposit accounts, which are less sensitive to changes in interest rates and can be re-priced rapidly.

The Company's interest rate risk, as monitored by management, has not significantly increased since year-end. Our earnings and cash flows are largely dependent upon our net interest income. Interest rates are highly sensitive to many factors that are beyond our control, including domestic and local economic conditions and the policies of various governmental and regulatory agencies and, in particular, the Federal Reserve. Further increases to prevailing interest rates could influence the interest we receive on loans and investments and the amount of interest we pay on deposits and borrowings. For instance, if our liabilities are positioned to reprice faster than our assets in a rising-rate environment, our net interest income could be detrimentally impacted as a result. Moreover, additional increases to the target range for the federal funds rate, combined with recent bank failures and ongoing geopolitical instability, raise the risk of economic recession. Any such downturn, especially in the regions in which we operate, may adversely affect our asset quality, deposit levels, loan demand and results of operations.

| **Item 4.** | **Controls and Procedures** |

---

The Company carried out an evaluation, under the supervision and with the participation of the Company's management, including the Company's Principal Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company's disclosure controls and procedures as defined in Rule 13a-15(e) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Based upon that evaluation, the Company's Principal Executive Officer and Chief Financial Officer concluded that as a result of the material weaknesses in internal control over financial reporting initially identified in "Management's Report on Internal Control over Financial Reporting" for the year ended December 31, 2024, and described below, the Company's disclosure controls and procedures were not effective as of September 30, 2025. Material weaknesses in internal controls over financial reporting, which impacted managements' determination regarding the Company's disclosure controls and procedures, were identified in the following areas:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• management review and activity-level controls over the period-end financial reporting process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the segregation of duties, review, posting, and approval of manual journal entries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the identification, prior approval, and disclosure of related party transactions.

*Changes in Internal Control over Financial Reporting*

Except as otherwise discussed above, there were no changes in our internal controls over financial reporting during the most recently completed fiscal quarter that have materially affected, or are reasonably likely to materially affect, the Company's internal control over financial reporting, including any corrective actions with regard to the control deficiencies that led to the material weaknesses in the Company's internal controls over financial reporting identified above.

The effectiveness of our disclosure controls and procedures and our internal control over financial reporting is subject to various inherent limitations, including cost limitations, judgments used in decision making, assumptions about the likelihood of future events, the soundness of our systems, the possibility of human error, and the risk of fraud. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions and the risk that the degree of compliance with policies or procedures may deteriorate over time. Because of these limitations, any system of disclosure controls and procedures or internal controls over financial reporting may not be successful in preventing all errors or fraud or in making all material information known in a timely manner to the appropriate levels of management.

*Remediation Plan*

The Company has initiated certain remedial measures to strengthen its controls as a result of the material weaknesses noted above. These include continued review of the overall design of its internal control environment, as well as the design and implementation of additional internal controls over the specific areas where material weaknesses were identified as detailed above. The Company has engaged a third party consultant to assist in performing a gap analysis of the control environment and enhancing the design and operation of controls related to financial reporting. The actions the Company is taking under its remediation plan are subject to ongoing management review and are also subject to Audit Committee oversight.

Each material weakness identified above cannot be considered remediated until the applicable remedial controls operate for a sufficient period of time and management has concluded, through testing, that these controls are operating effectively.

**Changes in U.S. trade policies, such as the implementation of tariffs, and other factors beyond the Company's control may adversely impact our business, financial condition and results of operations.**

The ongoing trade policies and tariff initiatives being pursued by the U.S. government under the administration of President Trump could present potential risks unique to the markets within which we operate. As a major producer and exporter of agricultural commodities, including corn, soybeans, and pork, Iowa is particularly vulnerable to negative consequences from such policy initiatives. As a result, the recent imposition of tariffs on a significant portion of imported goods, the increasing potential for ongoing retaliatory tariffs by foreign governments such as China, or other similar restrictions on international trade could lead to increased costs for domestic producers and consumers alike, as well as reduce demand abroad for U.S. exports, including those produced in the Bank's primary markets. Ultimately, prolonged trade tensions carry the potential to result in significant reductions in consumer spending, reduced economic growth, and decreased demand for other banking products and services. If these factors lead to financial strain on our borrowers, we may experience increased credit risk, higher loan delinquencies, and a potential decline in loan demand.

As a result, our financial performance, including credit quality and loan growth, could be adversely affected by these policy changes. While we actively monitor these developments and work closely with our agricultural customers, there is no assurance that we can fully mitigate the risks posed by tariff initiatives or other trade-related disruptions. These factors could materially affect our business, financial condition, and results of operations.

**Emerging financial technologies such as digital assets, stablecoins, and distributed ledger systems may reduce the demand for traditional banking services and create new competitive pressures that adversely affect our business.**

The rapid development and increasing regulatory acceptance of financial technologies such as digital assets (including cryptocurrencies and tokenized money), stablecoins, and distributed ledger technologies (DLT) could materially alter the landscape of financial services in the coming years. These technologies enable near-instantaneous value transfer, programmable money, and peer-to-peer settlement mechanisms, many of which may operate outside the traditional banking system.

Large technology companies, fintech platforms, and digital asset service providers—some of which are not subject to the same regulatory or capital constraints as depository institutions—are increasingly offering products that compete with core banking functions, such as payments, custody, lending, and liquidity management. The adoption of digital financial infrastructure by governments or central banks, such as central bank digital currencies (CBDCs), or by major corporate platforms could accelerate these shifts.

As a relatively small financial institution, we may be disproportionately impacted by these developments. Our ability to compete with larger institutions or well-capitalized technology entrants in developing or integrating such technologies is limited by our size, risk appetite, and regulatory obligations. A failure to adapt to or participate in these emerging ecosystems—either directly or through strategic partnerships—could erode our relevance in key banking functions, reduce our share of customer deposits and fee income, and adversely affect our long-term growth prospects and financial condition.

**Risks related to regulation of payment stablecoins and digital assets** 

Recent federal legislation, including the GENIUS Act enacted in mid-2025, established new regulatory requirements for payment stablecoins issued by banking organizations and their subsidiaries. Compliance with these requirements involves maintaining adequate asset reserves, extensive reporting obligations, independent audits, and increased supervisory oversight. Our potential involvement in issuing or supporting payment stablecoins could expose us to regulatory compliance risks, increased operational costs, and evolving legal uncertainties. Additionally, rapid changes in digital asset regulation or adverse regulatory interpretations could adversely affect our business strategies and prospects in this emerging market, which could materially impact our financial condition and results of operations.

(1) On July 26, 2005, the Company's Board of Directors authorized a program to repurchase up to 1,500,000 shares of the Company's common stock (the "2005 Stock Repurchase Program"). On August 9, 2022, the Company's Board of Directors authorized the expansion of the 2005 Stock Repurchase Program to allow an additional 750,000 shares for repurchase and the continuation through December 31, 2027. The Company expects the purchases pursuant to the 2005 Stock Repurchase Program to be made from time to time in private transactions at a price equal to the most recent quarterly independent appraisal of the shares of the Company's common stock and with the Board reviewing the overall results of the 2005 Stock Repurchase Program on a quarterly basis. All purchases made pursuant to the 2005 Stock Repurchase Program since its inception have been made on that basis. The amount and timing of stock repurchases will be based on various factors, such as the Board's assessment of the Company's capital structure and liquidity, the amount of interest shown by shareholders in selling shares of stock to the Company at their appraised value, and applicable regulatory, legal and accounting factors.
