Business Combination [Text Block]

NOTE 3 Business Combinations

HMN Financial, Inc.

On October 9, 2024, the Company completed the acquisition of 100% of the outstanding stock of HMN Financial, Inc. (Nasdaq: HMNF) and its wholly owned subsidiary, Home Federal Savings Bank (together, “Home Federal”), for a total purchase price of $123.6 million in common stock. As a result of the transaction, HMNF merged with and into Alerus Financial Corporation, and Home Federal Savings Bank merged with and into Alerus Financial, National Association. The acquisition enhances and extends the Company's presence in southern Minnesota. In connection with the acquisition, the Company issued 5.55 million shares of its common stock and acquired approximately $1.1 billion of identifiable assets. Goodwill of $38.9 million was recognized as a result of the merger and is not amortizable or deductible for tax purposes. The effects of the acquired assets and liabilities have been included in the consolidated financial statements since that date. As a result of the full integration of the operations of Home Federal, it is not practicable to determine all revenue or net income included in the Company's operating results relating to Home Federal since the date of acquisition as Home Federal results cannot be separately identified.

The Company determined that this acquisition constitutes a business combination and therefore was accounted for using the acquisition method of accounting. Accordingly, as of the date of the acquisition, the Company recorded the assets acquired, liabilities assumed and consideration paid at fair value based on management's best estimates using information available at the date of the acquisition and these estimates are subject to adjustment based on updated information not available at the time of the acquisition. The amount of goodwill arising from the acquisition consists largely of the synergies and economies of scale expected from combining the operations of the Company with Home Federal. Accrued income taxes and deferred taxes associated with the Home Federal acquisition were recorded on a provisional basis and could vary from the actual recorded balance and tax provisions when returns are finalized.

Direct costs related to the acquisition were expensed as incurred. Acquisition integration-related expenses were $10.0 million during the year ended December 31, 2024. There were no merger and acquisition expenses during the year ended December 31, 2023. These amounts were included within professional fees and assessments on the consolidated statements of income and are included in operating activities in the consolidated statements of cash flows.

The following table summarizes the estimated fair value of the assets acquired and liabilities assumed:

	*As recorded by*		*Fair Value*			*As recorded by*

The Company determined the fair value of the assets and liabilities acquired with the assistance of third-party specialists. The following is a description of the methods used to determine the fair values of significant assets and liabilities presented above.

Cash and cash equivalents

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

Investment securities available-for-sale

Fair values for AFS securities are based on quoted market prices, where available. If quoted market prices are not available, fair value estimates are based on observable inputs including quoted market prices for similar instruments, quoted market prices that are not in an active market or other inputs that are observable in the market. In the absence of observable inputs, fair value is estimated based on pricing models and/or discounted cash flow methodologies.

Net loans

A valuation of the loans portfolio was performed by a third-party as of the acquisition date in accordance with ASC 820 to assess the fair value of the loan portfolio, considering adjustments for interest rate risk, required equity return, servicing, credit, and liquidity risk. The loans portfolio was segmented into two groups including PCD loans and non-PCD loans. The non-PCD loans were pooled based on similar characteristics, such as loan type, interest rates, term to maturity, delinquency status, and collateral type. Non-PCD loans did not include any loans more than 60 days delinquent or any non-accrual status loans. Non-PCD loan pools were valued using a discounted cash flow analysis, based on the cash flows projected for each loan pool. The PCD loans were valued at the individual loan level or pooled with similar characteristics as non-PCD pooled loans. Individually valued PCD loans were valued using loan-level probability of default and loss given default estimates, reflecting the individual collateral position and circumstances of each loan. The fair value of pooled loans were calculated using a discounted cash flow analysis to estimate the fair value of the loans using assumptions for the coupon rates, remaining maturities, prepayment speeds, projected default probabilities, loss given defaults, and estimates of prevailing discount rates. The discount rate utilized to analyze fair value considered projected future interest rates based on forward rates, a spread over the forward curve, spreads for estimated servicing costs and illiquidity. The discounted cash flow approach models the credit losses directly in the projected cash flows. The Company estimated the credit risks and principal losses of the loans using the Company’s assumptions of probability of default, loss given default, and foreclosures.

The Company is required to record PCD assets, defined as a more-than-insignificant deterioration in credit quality since origination or issuance, at the purchase price plus the allowance for credit losses expected at the time of acquisition. Under this method, there is no credit loss expense affecting net income on acquisition of PCD assets. Changes in estimates of expected credit losses after acquisition are recognized in subsequent periods as credit loss expense (or reversal of credit loss expense) arise. Any non-credit discount or premium resulting from acquiring a pool of purchased financial assets with credit deterioration is allocated to each individual asset. At the acquisition date, the initial allowance for credit losses determined on a collective or individual basis is allocated to individual assets to appropriately allocate any non-credit discount or premium. For PCD loans, an allowance is recognized on day 1 by adding it to the fair value of the loan, which is the “day 1 amortized cost.” Non-PCD loans will have an allowance established on the acquisition date, which is recognized as an expense through the provision for credit losses. A day 1 allowance for credit losses on non-PCD loans of $7.3 million was recorded through the provision for loan losses within the consolidated statements of income. The following table provides details related to the fair value of acquired PCD loans:

(dollars in thousands)	PCD Loans
Par value of PCD loans at acquisition	$	173,922
Allowance for credit losses at acquisition		10,151
Discount at acquisition		(31,313	)
Fair value of PCD loans at acquisition	$	152,760

Land, premises and equipment

The fair values of land, premises and equipment are based on a combination of sales comparison approach and cost approach, using third-party appraisals and other analysis of value for land and premises.

Core deposit intangible

Core deposit intangible assets were determined using the income approach, after-tax cost savings method. This method estimates the fair value by discounting to present value the favorable funding spread attributable to the core deposit balances over their estimated average remaining life. The favorable funding spread is calculated as the difference in the alternative cost of funds and the net deposit cost. The core deposit intangible represents the costs saved by the Company between maintaining the existing deposits and obtaining alternative funds over the life of the deposit base. These costs are amortized using the sum of the years digits method over the estimated useful life of 10 years for the related deposits.

Deposits

The fair values for time deposits were estimated using a discounted cash flow analysis as no active trading market exists with which to obtain pricing on comparable financial instruments. The projected cash flows included assumptions of interest paid at maturity and no early withdrawals. The time deposits were combined based on maturity into cash flow buckets, and an average interest rate for each bucket was used in conjunction with the months to maturity to project the cash flows required to settle the time deposits upon maturity. The projected cash flows were discounted using a discount rate curve to reflect current market rates at the acquisition date which included the acquired time deposit rates prior to acquisition, rate sheets for the acquired time deposits, and FHLB advance rates as of the acquisition date. For transactional deposits, carrying amounts approximate fair value.

Accrued expenses and other liabilities

Accrued expenses and other liabilities include items such as accrued interest payable, accounts payable, accrued liabilities, and other miscellaneous liabilities. For all accrued expenses and other liabilities it was determined that the carrying value equals book value, except for accrued liabilities related to contract terminations. Contract termination accrued liabilities were not assumed by the Company as part of the business combination with HMNF, and were recorded separately in the postcombination period in accordance with the acquisition method of accounting.

Supplemental Pro Forma Financial Information (Unaudited)

The following table presents certain unaudited pro forma financial information for illustrative purposes only, for the years ended December 31, 2024 and 2023, as if Home Federal had been acquired on January 1, 2023. This unaudited pro forma information combines the historical results of Home Federal with the Company's consolidated historical results and includes certain adjustments reflecting the estimated impact of certain fair value adjustments for the respective periods. The pro forma information is not indicative of what would have occurred had the acquisition occurred as of the beginning of the year prior to the acquisition. The unaudited pro forma information does not consider any changes to the provision expense resulting from recording loan assets at fair value, cost savings or business synergies. As a result, actual amounts would have differed from the unaudited pro forma information presented and the differences could be significant.

	*Pro Formas (unaudited)*
	*for the years ended December 31,*
(dollars in thousands)	*2024*		*2023*
Net interest income after provision for credit losses	$	118,367	$	134,492
Noninterest income		121,765		88,510

Contract balances: 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. The Company’s noninterest income streams are largely based on transactional activity, or standard month-end revenue accruals such as asset management fees based on month-end market value. Consideration is often received immediately or shortly after the Company satisfies its performance obligation and revenue is recognized. The Company does not typically enter into long-term revenue contracts with customers, and therefore, does not experience significant contract balances. As of December 31, 2025 and 2024, the Company did not have any significant contract balances.

Contract acquisition costs: In connection with the adoption of Topic 606, 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 would have resulted from capitalizing these costs would have been amortized in one year or less.

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Business Combination [Policy Text Block]

Significant Accounting Policies (Policies)

12 Months Ended

Dec. 31, 2025

Accounting Policies [Abstract]

Business Combinations

The Company accounts for all business combinations using the acquisition method of accounting. Under this method of accounting, acquired assets and assumed liabilities are included with the acquirer’s accounts as of the date of acquisition, with any excess of purchase price over the fair value of the net assets acquired recognized as either finite lived intangibles or capitalized as goodwill. In addition, acquisition related costs and restructuring costs are recognized as period expenses as incurred. Fair values are subject to refinement over the measurement period, not to exceed one year after the closing date.

Consolidation, Policy [Policy Text Block]

Principles of Consolidation

The audited consolidated financial statements include the accounts of the Company and its subsidiaries in which the Company has a controlling interest. Significant intercompany balances and transactions have been eliminated in consolidation.

In the normal course of business, the Company may enter into a transaction with a variable interest entity (“VIE”). VIEs are legal entities whose investors lack the ability to make decisions about the entity’s activities, or whose equity investors do not have the right to receive the residual returns of the entity. The applicable accounting guidance requires the Company to perform ongoing quantitative and qualitative analysis to determine whether it must consolidate any VIE. The Company does have minor ownership interests but does not exert control over any VIE, and thus no VIEs are included in the audited consolidated financial statements.

Reclassification, Comparability Adjustment [Policy Text Block]

Reclassifications

Certain reclassifications have been made to prior year amounts, without impact to net income or total stockholders’ equity, to conform to the current year’s presentation.

Use of Estimates, Policy [Policy Text Block]

Use of Estimates

The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the fair value of assets acquired and liabilities assumed from an acquisition and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and the reported amounts of revenue and expenses during the reporting period. Actual results could differ from those estimates.

Material estimates that are particularly susceptible to significant change in the near term include the determination of the allowance for credit losses, valuation of reporting units for the purpose of testing goodwill for impairment, and fair values of loans acquired in business combinations.

Concentration Risk, Credit Risk, Policy [Policy Text Block]

Concentrations of Credit Risk

Substantially all of the Company’s lending activities are with clients located within North Dakota, Minnesota, and Arizona. At December 31, 2025 and 2024, respectively, 18.3% and 16.7% of the Company’s loan portfolio consisted of C&I loans that were not secured by real estate. The Company does not have any significant loan concentrations in any one industry or with any one client. Note 6 (Loans and Allowance for Credit Losses) discusses the Company’s loan portfolio.

The Company invests in a variety of investment securities and does not have any significant concentrations in any one industry or to any one issuer. Note 5 (Investment Securities) discusses the Company’s investment securities portfolio.

Cash and Cash Equivalents, Policy [Policy Text Block]

Cash and Cash Equivalents

For purposes of the consolidated statements of cash flows, cash and due from banks includes cash and cash equivalents, balances due from banks, and federal funds sold, all of which have an original maturity within 90 days. Cash flows from loans, FHLB stock, deposits, and short-term borrowings are reported net.

Interest-bearing deposits in banks are carried at cost.

Investment, Policy [Policy Text Block]

Investment Securities

Trading securities are reported on the Company’s consolidated balance sheet at fair value. Changes in fair value of trading securities are recorded in other noninterest income on the Company’s consolidated statements of income. Most of these securities are held in a rabbi trust account and invested in mutual funds. The trading securities will be used for future payments associated with the Company’s deferred compensation plan for eligible employees, executives, and directors.

Debt securities are classified as AFS, and are carried at estimated fair value with unrealized gains and losses reported in OCI. Realized gains (losses) on AFS debt securities are included in net gains (losses) on investment securities in OCI. Gains (losses) on sales of investment securities are determined using the specific identification method on the trade date. The amortization of premiums and accretion of discounts are recognized in interest income using methods approximating the interest method over the period to maturity.

For AFS debt securities in an unrealized loss position, the Company evaluates the securities to determine whether the decline in fair value below the amortized cost basis, or impairment, is due to credit-related factors or noncredit-related factors. Any impairment that is not credit related is recognized in OCI, net of applicable taxes. Credit-related impairment is recognized as an ACL related to AFS debt securities on the balance sheet, limited to the amount by which the amortized cost basis exceeds the fair value, with a corresponding adjustment to earnings as an expense (credit) within the provision for credit losses on the consolidated statements of income. Both the ACL and the adjustment to net income may be reversed if conditions change. However, if the Company intends to sell an impaired available-for-sale investment security or is required to sell such a security before recovering its amortized cost basis, the entire impairment amount must be recognized in earnings with a corresponding adjustment to the security’s amortized cost basis. Because the security’s amortized cost basis is adjusted to fair value, there is no ACL in this situation. Accrued interest receivable is excluded from the estimate of credit losses.

In evaluating AFS debt securities in unrealized loss positions for impairment and the criteria regarding its intent or requirement to sell such securities, the Company considers the extent to which fair value is less than amortized cost, whether the securities are issued by the federal government or its agencies, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuers’ financial condition, macroeconomic trends of the industry specific to the security, and any other adverse conditions specifically related to the security, among other factors.

As of December 31, 2025 and 2024, there was no ACL carried on the Company’s AFS debt securities nor were there any permanent write-offs for the years ended December 31, 2025, 2024 and 2023. Refer to Note 5 (Investment Securities) for further discussion.

Certain debt securities that the Company has an intent to hold to maturity are classified as HTM, and recorded at amortized cost. Interest earned on HTM debt securities is included in interest income. Amortization or accretion of premiums and discounts is also recognized in interest income using the effective interest method over the contractual life of the security and is adjusted to reflect actual prepayments. Transfers of debt securities from AFS to HTM are made at fair value at the date of transfer. Unrealized holding gains and losses at the date of transfer are included in OCI and in the carrying value of HTM security and are amortized over the remaining life of the security.

Management measures expected credit losses on HTM debt securities on a collective basis by major security type. The Company evaluates HTM debt securities by credit rating and an external study, updated quarterly, that includes historical information such as probability of default and loss going back several years. Accrued interest receivable on HTM debt securities is excluded from the estimate of credit losses.

A change in the ACL related to HTM debt securities is recorded as an expense (credit) within the provision for credit losses on the consolidated statements of income.

There was $123 thousand and $131 thousand of ACL carried on the Company’s HTM debt securities as of December 31, 2025 and 2024, respectively. For the years ended December 31, 2025, 2024 and 2023, there were no permanent write-offs. Refer to Note 5 (Investment Securities) for further discussion.

Nonmarketable Equity Securities

Nonmarketable equity securities include the Bank’s required investments in the stock of the FHLB of Des Moines and the Federal Reserve Bank (the “FRB”). The Bank is a member of the FHLB as well as its regional FRB. Members are required to own a certain amount of stock based of the level of borrowing and other factors, and may invest in additional amounts. FHLB stock and FRB stock are carried at cost, classified as other assets, and periodically evaluated for impairment based on ultimate recovery of par value. Both cash and stock dividends are reported as income.

Financing Receivable, Held-for-Sale [Policy Text Block]

Loans Held for Sale

Loans originated and intended for sale in the secondary market are carried at the lower of cost or estimated fair value in the aggregate. Net unrealized losses are recognized through a valuation allowance by charges to income. Gains (losses) on loan sales are recorded in mortgage banking revenue on the consolidated statements of income.

Financing Receivable [Policy Text Block]

Loans

Loans are stated at the amount of unpaid principal, reduced by an allowance for credit losses. Loans that management has the intent and ability to hold for the foreseeable future, until maturity or pay-off, generally are reported at their outstanding unpaid principal balances adjusted for charge-offs, and the allowance for credit losses. Loan fees received that are associated with originating or acquiring certain loans are deferred, net of costs, and amortized over the life of the loan as a yield adjustment to interest income.

The accrual of interest on loans is discontinued at the time the loan is 90 days past due unless the credit is well-secured and in process of collection. Consumer loans are typically charged-off no later than 120 days past due. Past due status is based on contractual terms of the loan. In all cases, loans are placed on nonaccrual or charged-off at an earlier date if collection of principal or interest in considered doubtful.

All interest accrued but not collected for loans that are placed on nonaccrual or charged-off is reversed against interest income. The interest on these loans is accounted for on the cash-basis or cost-recovery method until qualifying for return to accrual. Loans are returned to accrual status when all the principal and interest amounts contractually due are brought current and future payments are reasonably assured.

Credit Loss, Financial Instrument [Policy Text Block]

ACL on Loans

Upon adoption of ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”), as amended, effective January 1, 2023, the Company used a modified-prospective approach. Upon adoption, the Company recorded a cumulative-effective adjustment of $4.5 million reducing retained earnings, with a corresponding adjustment of $172 thousand increasing the ACL on HTM debt securities, $3.9 million increasing the ACL on loans, and $1.9 million increasing other liabilities for the ACL on off-balance sheet credit exposures.

Under the CECL accounting standard the ACL is a valuation estimated at each balance sheet date and deducted from the amortized cost basis or unpaid principal balance of loans held for investment to present the net amount expected to be collected.

The Company estimates the ACL based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for collection of cash and charge-offs, as well as applicable accretion or amortization of premium, discount and net deferred fees or costs, or unpaid principal balance for PCD loans, which is the sum of the purchase price, ACL, and discount or premium. In the event that collection of principal becomes uncertain, the Company has policies in place to reverse accrued interest in a timely manner. Therefore, the Company has made the policy election to exclude accrued interest from the measurement of ACL.

The ACL on loans is increased by charges to provision for credit losses and reduced by charge-offs, net of recoveries. Management evaluates the appropriateness of the ACL on loans quarterly. This evaluation is inherently subjective as it requires material estimates that may be susceptible to significant change from period to period. The ACL on loans is presented on the consolidated balance sheets.

Loans past due 30 days or more are considered delinquent. In general, secured loans that are delinquent for 90 consecutive days are placed on non-accrual status and may be subject to individual loss assessment in accordance with established internal policy. In general, unsecured loans that are delinquent for 90 consecutive days have a provision taken for the full amount of the loan.

Effective January 1, 2023, the Company adopted prospectively ASU 2022-02, Financial Instruments – Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures (“ASU 2022-02”). ASU 2022-02 provided guidance that eliminated the recognition and measurement of TDRs. Following the adoption of this guidance, the Company evaluates all loan modifications made to borrowers experiencing financial difficulty according to the accounting guidance for loan refinancing and restructuring to determine whether such loan modification should be accounted for as a new loan or a continuation of the existing loan. All loans previously recognized as a TDR will continue to be classified as such until the loan is paid off. Refer to Note 6 (Loans and Allowance for Credit Losses) for further discussion.

The ACL on loans reduces the loan portfolio to the net amount expected to be collected, and represents the expected losses over the life of all loans at the reporting date. The allowance incorporates forward-looking information and applies a reversion methodology beyond the reasonable and supportable forecast.

The ACL on loans represents the Company's estimated risk of loss within its loan portfolio as of the reporting date. To appropriately measure expected credit losses, management disaggregates the loan portfolio into pools of loans with similar risk characteristics (i.e. “segments”). The Company utilizes a discounted cash flow or expected loss (collectively loss driver models) approach to calculate the expected loss for each segment. Within the loss driver models, a PD and LGD assumption is applied to calculate the expected loss for each segment. PD is the probability the asset will default within a given timeframe and LGD is the percentage of assets not expected to be collected due to default. The Company's PD and LGD assumptions are derived using a combination of external data and internal historical default and loss experience.

As of December 31, 2025, the primary macroeconomic drivers used within the loss driver models included forecasts of National Unemployment, changes in National GDP, and changes in the National Housing Price Index. These macroeconomic drivers may change from time to time as a result of management’s assessment of continued suitability of each factor.

To determine its reasonable and supportable forecast, management may leverage macroeconomic forecasts obtained from various reputable sources, which may include, but is not limited to, the Federal Open Market Committee forecast and other publicly available forecasts from well recognized, leading economists or firms. External baseline forecasts are supplemented by an assessment of the likelihood of standard alternative scenarios occurring over the forecast period. The Company’s reasonable and supportable forecast period generally ranges from one to two years, depending on the facts and circumstances of the current state of the economy, portfolio segment and management’s judgement of what can be reasonably supported. The model reversion period generally ranges from one to two years, and it also depends on the current state of the economy and management’s judgments of such. Management monitors and assesses the forecast and reversion period at least annually. The Company used a one-year forecast and reversion period to calculate the ACL on loans as of December 31, 2025 and 2024, except for PCD agricultural land and PCD agricultural production loans which utilize static PD and LGD assumptions.

The ACL on loans is calculated over a loan’s contractual life. For term loans, the contractual life is calculated based on the maturity date. For revolving loans, the contractual life is based on either the estimated maturity date or a default date. For revolving loans with no stated maturity date, the contractual life is calculated based on the annual attrition rate for the pool. The contractual term does not include expected extension, renewals or modifications.

The Company's loan portfolio is segmented into 13 homogenous pools as follows based on the various risk profiles of the Company's loans:

●

Commercial & Industrial

●

CRE – Construction, Land & Development

●

CRE – Multifamily

●

CRE – Non-Owner Occupied

●

CRE – Owner Occupied

	●	Agricultural – Land
	●	Agricultural – Production

●

Residential – First Lien

●

Residential – Construction

●

Residential – HELOC

●

Residential – Junior Lien

●

Other Consumer

●

Paycheck Protection Program

In calculating the ACL on loans, the contractual life of a loan must be adjusted for prepayments to arrive at expected cash flows. The Company models term loans using an annualized prepayment. When the Company has a specific expectation of differing payment behavior for a given loan, the loan may be evaluated individually. For revolving loans that do not have a principal payment schedule, a curtailment rate is factored into the cash flow.

The ACL on loans evaluation may also consider various qualitative factors that are likely to cause estimated credit losses to differ from historical loss experience, such as: actual or expected changes in economic trends and conditions, changes in the value of underlying collateral for loans, changes to lending policies, underwriting standards and/or management personnel performing such functions, delinquency and other credit quality trends, credit risk concentrations, if any, changes to the nature of the Company's business impacting the loan portfolio, and other external factors, that may include, but are not limited to, results of internal loan reviews, examinations by bank regulatory agencies, or other such events such as a natural disaster.

Certain loans are individually evaluated for estimated credit losses, including those that are classified as substandard or doubtful and are on non-accrual or that have other unique characteristics differing from the segment. Specific reserves are established when appropriate for such loans based on the present value of expected future cash flows of the loan or the estimated realizable value of the collateral, if any.

Management may also adjust its assumptions to account for differences between expected and actual losses from period-to-period. The variability of management’s assumptions could alter the ACL on loans materially and impact future results of operations and financial condition. The loss estimation models and methods used to determine the allowance for credit losses are continually refined and enhanced.

Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]

Off Balance Sheet Credit Related Financial Instruments

In the ordinary course of business, the Company enters into commitments to extend credit, including commitments under credit arrangements, commercial letters of credit, and standby letters of credit. Such financial instruments are recorded when they are funded.

Allowance For Credit Losses on Off-Balance-Sheet Credit Exposure, Policy [Policy Text Block]

ACL on Off Balance Sheet Credit Exposures

The ACL on off balance sheet credit exposures, excluding those that are unconditionally cancellable by the Company, estimates the expected losses on the unfunded commitments and standby letters of credit at each reporting date. To appropriately measure expected credit losses, management disaggregates the loan portfolio into similar risk characteristics, identical to those determined for the loan portfolio. An estimated funding rate is then applied to the qualifying unfunded loan commitments and standby letters of credit using the Company’s own historical experience to estimate the expected funded for each loan segment as of the reporting date. Once the expected funded amount for each loan segment is determined, the loss rate, which is the calculated expected loan loss as a percent of the amortized cost basis for each loan segment, is applied to calculate the ACL on off-balance sheet credit exposures as of the reporting date.

The ACL on off balance sheet credit exposures is presented within accrued expenses and other liabilities on the consolidated balance sheet. A charge (credit) to provision for credit losses on the consolidated statements of income is made to account for the change in the ACL on off-balance sheet exposures between reporting periods. The ACL on off-balance sheet credit related financial instruments was $3.9 million and $7.5 million as of December 31, 2025 and 2024, respectively.

Accrued Interest Receivable [Policy Text Block]

Accrued Interest Receivable

Accrued interest receivable, including receivables related to investments and loans, is excluded from the measurement of the ACL. Accrued interest receivable is written off by reversing previously recognized interest income. The Company has a robust policy in place to write off accrued interest when a loan is placed on non-accrual. For loans, a write-off typically occurs when a loan has been in default for 90 days or more.

Property, Plant and Equipment, Policy [Policy Text Block]

Land, Premises and Equipment, Net

Land is carried at cost. Other premises and equipment are carried at cost net of accumulated depreciation. Depreciation is computed on a straight-line method based principally on the estimated useful lives of the assets. Maintenance and repairs are expensed as incurred while major additions and improvements are capitalized. Gains (losses) on dispositions are included in current operations.

Life Insurance, Corporate or Bank Owned, Policy [Policy Text Block]

Bank Owned Life Insurance

The Company has purchased life insurance policies on certain key executives. Bank owned life insurance is recorded at its cash surrender value, or the amount that can be realized, if lower.

Goodwill and Intangible Assets, Policy [Policy Text Block]

Goodwill and Other Intangibles, Net

Goodwill resulting from acquisitions is not amortized, but is tested for impairment annually. As part of its testing, the Company performs a quantitative analysis to determine whether it is more likely than not that the estimated fair value of a reporting unit is less than its carrying amount. If the Company determines the estimated fair value of a reporting unit is less than its carrying amount using certain qualitative factors, the Company then compares the estimated fair value of the goodwill with its carrying amount, and then measures impairment loss by comparing the estimated fair value of goodwill with the carrying amount of that goodwill.

Significant judgment is applied when goodwill is assessed for impairment. This judgment includes developing cash flow projections, selecting appropriate discount rates, identifying relevant market comparables, incorporating general economic and market conditions, and selecting an appropriate control premium. At December 31, 2025, the Company believes it did not have any impairment based on the estimated fair value of the reporting units.

Intangible assets determined to have definite lives are amortized over the remaining useful lives using either the sum-of-the-years digits or straight-line method. Intangible and other long-lived assets are reviewed for impairment whenever events occur, or circumstances indicate that the carrying amount may not be recoverable.

Mortgage Banking Activity [Policy Text Block]

Mortgage Banking

Residential real estate loans are originated for purposes of being held for investment and held for sale into the secondary market. The transfer of these financial assets is accounted for as a sale when control over the asset has been surrendered. Control is deemed to be surrendered when the asset has been isolated from the Company, the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred asset, and the Company does not maintain effective control over the transferred asset through an agreement to repurchase it before its maturity. The Company records the gain on sale of the financial asset within mortgage banking income on the consolidated statements of income.

The Company generates mortgage servicing rights (“MSR”) from its mortgage banking business. When the Company sells mortgage loans in the secondary market and retains the right to service these loans, a servicing right asset is capitalized at the time of the sale when the benefits of servicing are deemed to be greater than adequate compensation for performing the servicing activities. MSRs represent the then-current fair value of future net cash flows expected to be realized from performing servicing activities. The Company has elected to subsequently measure MSRs at fair value and report changes in fair value in current period income as a component of mortgage banking income on the consolidated statements of income as of and for the years ended December 31, 2025 and 2024. MSRs are recorded at fair value based on assumptions through a third-party valuation service. The valuation model incorporates assumptions that are observable in the marketplace and that market participants would use in estimating future net servicing income, such as the servicing cost per loan, the discount rate, the escrow float, and inflation rate, ancillary income, prepayment speeds and default rates and losses.

MSRs were accounted for at the lower of amortized cost or fair value as of and for the year ended December 31, 2023. MSRs were evaluated for impairment based upon the estimated fair value of the rights compared to amortized cost. Impairment was determined by stratifying rights by predominant characteristics, such as interest rates and terms. Impairment was recognized through a valuation allowance for an individual tranche, to the extent that estimated fair value was less than the capitalized amount for the tranche. If the Company later determined that all or a portion of the impairment no longer existed for a particular tranche, a reduction of the allowance was recorded as an increase to income.

Servicing fee income is recorded for fees earned for servicing loans. The fees are based on a contractual percentage of the outstanding principal, or a fixed amount per loan, and are recorded as income when earned. The amortization of servicing rights is netted against loan servicing fee income and included in other noninterest income.

Impairment or Disposal of Long-Lived Assets, Policy [Policy Text Block]

Impairment of Long Lived Assets

The Company tests long lived assets for impairment whenever events or changes in circumstances indicate the carrying amount of an asset may not be recoverable. Recoverability of assets to be held and used is measured by comparing the carrying amount of an asset to the future undiscounted net cash flows expected to be generated by the asset.

In the event such an asset is considered impaired, the impairment to be recognized is measured by the amount by which the carrying value of the asset exceeds the estimated fair value of the asset. Assets to be disposed of are reported at the lower of the carrying value of estimated fair value less estimated costs to sell.

Lessee, Leases [Policy Text Block]

Leases

The Company leases office space, space for ATM locations and certain branch locations under noncancellable operating leases, several of which have renewal options to extend the lease terms. Upon commencement of a new lease, the Company will recognize a right-of-use (“ROU”) asset and a corresponding lease liability. The Company makes the decision on whether to renew an option to extend a lease by considering various factors. The Company will recognize an adjustment to ROU asset and lease liability when lease agreements are amended and executed. The discount rate used in determining the present value of lease payments is based on the lessor’s implicit rate in the lease if known or the Company’s incremental borrowings rate for borrowing terms similar to each lease at commencement date. The Company has lease agreements with lease and non-lease components, which are generally accounted for separately. For real estate leases, non-lease components, such as common area maintenance charges, real estate taxes and insurance, are not included in the measurement of the lease liability since they are generally able to be segregated. The Company has elected the short-term lease recognition exemption for all leases that qualify.

Financing Receivable, Held-for-Investment, Foreclosed Asset [Policy Text Block]

Foreclosed Assets

Assets acquired through loan foreclosure are included in other assets and are initially recorded at estimated fair value less estimated selling costs. The estimated fair value of foreclosed assets is evaluated regularly and any decreases in value along with holding costs, such as taxes, insurance and utilities, are reported in noninterest expense.

Transfers and Servicing of Financial Assets, Transfers of Financial Assets, Policy [Policy Text Block]

Transfers of Financial Assets and Participating Interests

Transfers of financial assets are accounted for as sales when control over assets has been surrendered or in the case of loan participation, a portion of the asset has been surrendered and meets the definition of a “participating interest.” Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the rights to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Should the transfer not meet these three criteria, the transaction is treated as a secured financing.

Loans serviced for others are not included in the accompanying consolidated balance sheets. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors and collection and foreclosure processing.

Debt, Policy [Policy Text Block]

Short-Term and Long-Term Borrowings

Short-term borrowings are those that, at time of origination, are scheduled to mature within one year, where borrowings with maturity dates of three months or less being presented net, and borrowings with maturity dates in excess of three months but less than one year being presented gross. The Company’s short-term borrowings include, but are not limited to, FHLB overnight and FHLB advances, federal funds purchased, and line-of-credit advances.

Long-term borrowings are those that, at time of origination, are scheduled to mature in one or more years. The Company’s long-term borrowings include, but are not limited to, FHLB advances, subordinated notes payable, trust preferred securities, and junior subordinated debentures.

Short-term and long-term borrowings on the consolidated statements of income are presented net of unamortized issuance costs, if any, and amortized over the life of the borrowing.

The Company is required to post collateral for certain borrowings, for which it generally posts loans and/or investment securities as collateral.

Derivatives, Policy [Policy Text Block]

Derivatives and Hedging Activities

In the ordinary course of business, the Company enters into derivative transactions to manage various risks and to accommodate the business requirements of its clients.

Derivative instruments are reported in other assets or other liabilities at estimated fair value. The Company formally documents relationships between hedging instruments and hedged items, as well as its risk management objectives and strategy for undertaking various hedge transactions. The Company also assesses, both at the hedge’s inception and on an ongoing basis, whether the derivatives that are used in hedging transactions are effective in offsetting changes in cash flows or fair values of hedged items. Derivatives designated and qualifying as a hedge of the exposure to changes in the fair value of an asset, liability, or firm commitment attributable to a particular risk, such as interest rate risk, are considered fair value hedges. Changes in fair value of a derivative that qualifies as a fair value hedge and the change in fair value of the hedged item are both recorded in earnings and offset each other when the transaction is effective. Derivatives designated and qualifying as a hedge of the exposure to variability in expected future cash flows, or other types of forecasted transactions, are considered cash flow hedges. Changes in fair value of a derivative that is effective and that qualifies as a cash flow hedge are recorded in OCI and are reclassified into earnings when the forecasted transaction or related cash flows affect earnings. The Company will also enter into derivative contracts that are intended to economically hedge certain of its risk, even though hedge accounting does not apply or the Company elects not to apply hedge accounting. Changes in the fair value of the derivatives not designated are recognized directly in earnings.

Revenue [Policy Text Block]

Noninterest Income

Specific guidelines are established for recognition of certain noninterest income components related to the Company’s audited consolidated financial statements. In accordance with Topic 606, revenues are recognized when control of promised goods or services is transferred to customers in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. To determine revenue recognition for arrangements that the Company determines are within the scope of Topic 606, the Company performs the following five steps: (1) identify the contract(s) with a customer; (2) identify the performance obligations in the contract; (3) determine the transaction price; (4) allocate the transaction price to the performance obligations in the contract; and (5) recognize revenue when (or as) the Company satisfies a performance obligation.

The Company only applies the five-step model to contracts when it is probable that the entity will collect the consideration it is entitled to in exchange for the goods or services it transfers to the customer. At contract inception, once the contract is determined to be within the scope of Topic 606, the Company assesses the goods or services that are promised within each contract and identifies those that contain performance obligations and assesses whether each promised good or service is distinct. The Company then recognizes as revenue the amount of the transaction price that is allocated to the respective performance obligation when (or as) the performance obligation is satisfied. The material groups of noninterest income that this methodology is applied to are defined as follows:

Retirement and benefit services: Retirement and benefit services income is primarily comprised of fees earned from the administration of retirement plans, record-keeping, compliance services, health savings accounts, and flexible benefit plans. Fees are earned based on a combination of the market value of assets under administration and transaction-based fees for services provided. Fees that are determined based on the market value of the assets under administration are generally billed monthly or quarterly in arrears and recognized monthly as the Company’s performance obligations are met. Other transaction-based fees are recognized monthly as the performance obligation is satisfied.

Wealth: Wealth income is earned from a variety of sources including trust administration and other related fiduciary services, custody, investment management and advisory services, and brokerage. Fees are based on the market value of the assets under management and are generally billed monthly in arrears and recognized monthly as the Company’s performance obligations are met. Commissions on transactions are recognized on a trade-date basis as the performance obligation is satisfied at the point in time in which the trade is processed. Other related services are based on a fixed fee schedule and the revenue is recognized when the services are rendered, which is when the Company has satisfied its performance obligation.

Service charges on deposit accounts: Service charges on deposit accounts primarily consist of account analysis fees, monthly maintenance fees, overdraft fees, and other deposit account related fees. Overdraft fees and certain service charges are fixed, and the performance obligation is typically satisfied at the time of the related transaction. The consideration for analysis fees and monthly maintenance fees are variable as the fee can be reduced if the customer meets certain qualifying metrics. The Company’s performance obligations are satisfied at the time of the transaction or over the course of a month.

Other noninterest income: Other noninterest income components include debit card interchange fees, bank-owned life insurance income and miscellaneous transactional fees. Income earned from these revenue streams is generally recognized concurrently with the satisfaction of the performance obligation.

Advertising Cost [Policy Text Block]

Advertising Costs

Advertising costs are expensed as incurred.

Tax Credit Investments [Policy Text Block]

Tax Credit Investments

The Company invests in qualified affordable housing projects for the purpose of community reinvestment and obtaining tax credits. These investments are included in other assets on the balance sheet, and any unfunded commitments in accrued expenses and other liabilities on the balance sheet. The qualified affordable housing projects are accounted for under the proportional amortization method. Under the proportional amortization method, the initial cost of the investment is recognized over the period that the Company expects to receive the tax credits, with the expense included within income tax expense on the consolidated statements of income. Management analyzes these investments for potential impairment when events or changes in circumstances indicate that it is more likely than not that the carrying amount of the investment will not be realized. An impairment loss is measured as the amount by which the carrying amount of an investment exceeds its fair value.

These investments are considered to be variable interest entities and involve significant management judgments, including a determination of which entities have the power to direct activities, and whether these entities are variable interest entities. The Company's maximum exposure to loss related to its investments in these unconsolidated variable interest entities is limited to the carrying amount of the investment, net of any unfunded capital commitments and previously recorded tax credits, which remain subject to recapture by taxing authorities based on compliance features required to be met at the project level.

Income Tax, Policy [Policy Text Block]

Income Taxes

Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax basis. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance would be recognized if it is “more likely than not” that the deferred tax asset would not be realized.

These calculations are based on many complex factors including estimates of the timing of reversals of temporary differences, the interpretation of federal and state income tax laws, and a determination of the differences between the tax and the financial reporting basis of assets and liabilities. Actual results could differ significantly from the estimates and interpretations used in determining the current and deferred income tax liabilities.

The Company follows standards related to Accounting for Uncertainty in Income Taxes. These rules establish a higher standard for tax benefits to meet before they can be recognized in a Company’s consolidated financial statements. The Company can recognize in financial statements the impact of a tax position taken, or expected to be taken, if it is more likely than not that the position will be sustained on an audit based on the technical merit of the position. See Note 20 (Income Taxes) for additional disclosures. The Company recognizes both interest and penalties as components of other operating expenses.

The amount of the uncertain tax position was not determined to be material. It is not expected that the unrecognized tax benefit will be material within the next 12 months. The Company did not incur any interest or penalties in 2025, 2024, or 2023.

The Company files consolidated federal and state income tax returns. The Company is no longer subject to U.S. federal or state tax examinations by tax authorities for years before 2021.

Comprehensive Income, Policy [Policy Text Block]

Comprehensive Income

Recognized revenue, expenses, gains, and losses are included in net income. Certain changes in assets and liabilities, such as unrealized gains (losses) on debt securities, unrealized gains (losses) on cash flow hedging derivatives, reclassification adjustments for losses (gains) realized in income, and unrealized gains (losses) on other derivatives, are reported as a separate component of the equity section of the consolidated balance sheets. Such items, along with net income, are components of comprehensive income.

Share-Based Payment Arrangement [Policy Text Block]

Stock Compensation Plans

Stock compensation accounting guidance requires that the compensation cost relating to share-based payment transactions be recognized in financial statements. The cost will be measured based on the grant date estimated fair value of the equity or liability instruments issued. The grant date estimated fair value is determined using the closing price of the Company’s common stock. The stock compensation accounting guidance requires that compensation cost for all stock awards be calculated and recognized over the employee’s service period, generally defined as the vesting period. For awards with graded-vesting, compensation cost is recognized on a straight-line basis over the requisite service period for the entire award.

Earnings Per Share, Policy [Policy Text Block]

Earnings per Share

Earnings per share are calculated utilizing the two-class method. Earnings per share calculations include shares related to the Alerus Financial Corporation Employee Stock Ownership Plan. Basic earnings per share is calculated by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted-average number of common shares outstanding. Diluted earnings per share are calculated by dividing the sum of distributed earnings to common stockholders and undistributed earnings allocated to common stockholders by the weighted-average number of shares adjusted for the dilutive effect of common stock awards.

Note 29 - Fair Value of Assets and Liabilities

Fair Value Disclosures [Text Block]

NOTE 29 Fair Value of Assets and Liabilities

The Company categorizes its assets and liabilities measured at estimated fair value into a three level hierarchy based on the priority of the inputs to the valuation technique used to determine estimated fair value. The estimated fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used in the determination of the estimated fair value measurement fall within different levels of the hierarchy, the categorization is based on the lowest level input that is significant to the estimated fair value measurement. Assets and liabilities valued at estimated fair value are categorized based on the following inputs to the valuation techniques as follows:

Level 1—Inputs that utilize quoted prices (unadjusted) in active markets for identical assets or liabilities that an entity has the ability to access.

Level 2—Inputs that include quoted prices for similar assets and liabilities in active markets and inputs that are observable for the asset or liability, either directly or indirectly, for substantially the full term of the financial instrument. Estimated fair values for these instruments are estimated using pricing models, quoted prices of investment securities with similar characteristics, or discounted cash flows.

Level 3—Inputs that are unobservable inputs for the asset or liability, which are typically based on an entity’s own assumptions, as there is little, if any, related market activity. Subsequent to initial recognition, the Company may re-measure the carrying value of assets and liabilities measured on a nonrecurring basis to estimated fair value. Adjustments to estimated fair value usually result when certain assets are impaired. Such assets are written down from their carrying amounts to their estimated fair value.

Professional standards allow entities the irrevocable option to elect to measure certain financial instruments and other items at estimated fair value for the initial and subsequent measurement on an instrument-by-instrument basis. The Company adopted the policy to value certain financial instruments at estimated fair value. The Company has not elected to measure any existing financial instruments at estimated fair value; however, it may elect to measure newly acquired financial instruments at estimated fair value in the future.

Recurring Basis

The Company uses estimated fair value measurements to record estimated fair value adjustments to certain assets and liabilities and to determine estimated fair value disclosures. For additional information on how the Company measures estimated fair value refer to Note 1 (Significant Accounting Policies).

The following tables present the balances of the assets and liabilities measured at estimated fair value on a recurring basis at December 31, 2025 and 2024:

The following is a description of the valuation methodologies used for instruments measured at estimated fair value on a recurring basis, as well as the general classification of such instruments pursuant to the valuation hierarchy.

Investment Securities, Trading for Deferred Compensation

The fair value of trading securities for deferred compensation is reported using market quoted prices, as such securities and underlying securities are actively traded and no valuation adjustments have been applied and therefore are classified as Level 1.

Investment Securities, Available-for-sale

Generally, debt securities are valued using pricing for similar securities, recently executed transactions, and other pricing models utilizing observable inputs and therefore are classified as Level 2.

Derivatives

All of the Company’s derivatives are traded in over the counter markets where quoted market prices are not readily available. For these derivatives, estimated fair value is measured using internally developed models that use primarily market observable inputs, such as yield curves and option volatilities, and accordingly, classify as Level 2. Examples of Level 2 derivatives are basic interest rate swaps and forward contracts.

Servicing Rights

Servicing rights are measured based on valuation techniques using Level 3 inputs. The Company uses a discounted cash flow model that incorporates assumptions market participants would use in estimating the fair value of servicing rights, including, but not limited to, conditional prepayment rate utilizing the Public Securities Association (PSA) convention, servicing fee rate, ancillary fees, and cost to service.

Nonrecurring Basis

Certain assets are measured at estimated fair value on a nonrecurring basis. These assets are not measured at estimated fair value on an ongoing basis; however, they are subject to estimated fair value adjustments in certain circumstances, such as when there is evidence of impairment or a change in the amount of previously recognized impairment.

The estimated fair value of certain assets on a nonrecurring basis for the years ended December 31, 2025 and 2024 consisted of the following:

	*December 31, 2025*
(dollars in thousands)	*Level 1*		*Level 2*		*Level 3*		*Total*
Collateral dependent loans		—		—		33,484		33,484
Foreclosed assets		—		—		308		308

	*December 31, 2024*
(dollars in thousands)	*Level 1*		*Level 2*		*Level 3*		*Total*
Collateral dependent loans	$	—	$	—	$	34,088	$	34,088

Loans Held for Sale

Loans originated and held for sale are carried at the lower of cost or estimated fair value. The Company obtains quotes or bids on these loans directly from purchasing financial institutions. Typically, these quotes include a premium on the sale and thus these quotes indicate estimated fair value of the held for sale loans is greater than cost.

Impairment losses for loans held for sale that are carried at the lower of cost or estimated fair value represent additional net write-downs during the period to record these loans at the lower of cost or estimated fair value subsequent to their initial classification as loans held for sale.

Collateral Dependent Loans

The estimated fair value of collateral dependent loans is based on fair value, less estimated cost to sell. Collateral dependent impaired loans are classified within Level 3 of the fair value hierarchy.

The Company considers appraisal analysis as the starting point for determining fair value, and then considers other factors and events in the environment that may affect fair value. Values of the collateral underlying collateral dependent loans are obtained when the loan is determined to be collateral dependent, and subsequently as deemed necessary by management. Values are reviewed for accuracy and consistency by management. The ultimate collateral values are reduced by discounts to consider lack of marketability and estimated cost to sell if repayment or satisfaction of the loan is dependent on the sale of the collateral.

Foreclosed Assets

Assets acquired through loan foreclosure are included in other assets and are initially recorded at estimated fair value less estimated selling costs. The estimated fair value of foreclosed assets is evaluated regularly and any decreases in value along with holding costs, such as taxes, insurane and utilities, are reported in noninterest expense.

The valuation techniques and significant unobservable inputs used to measure Level 3 estimated fair value as of December 31, 2025 and 2024, respectively, were as follows:

			*December 31, 2025*
(dollars in thousands)								*Weighted*
Asset Type	*Valuation Technique*	*Unobservable Input*	*Fair Value*		*Range*			*Average*
Collateral dependent loans	Appraisal value	Property specific adjustment		33,484		10 - 35	%		30.7	%
Foreclosed assets	Appraisal value	Property specific adjustment		308		10.0	%		10.0	%
Servicing rights	Discounted cash flows	Prepayment speed assumptions		6,383		130 - 730			239
		Discount rate				10.0	%		10.0	%

			*December 31, 2024*
(dollars in thousands)								*Weighted*
Asset Type	*Valuation Technique*	*Unobservable Input*	*Fair Value*		*Range*			*Average*
Collateral dependent loans	Appraisal value	Property specific adjustment	$	34,088		10 - 35	%		28.9	%
Servicing rights	Discounted cash flows	Prepayment speed assumptions		7,918		103 - 495			165
		Discount rate				10.5	%		10.5	%

Disclosure of estimated fair value information about financial instruments, for which it is practicable to estimate that value, is required whether or not recognized in the consolidated balance sheets. In cases in which quoted market prices are not available, estimated fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. In that regard, the derived estimated fair value estimates cannot be substantiated by comparison to independent markets and, in many cases could not be realized in immediate settlement of the instruments. Certain financial instruments, with an estimated fair value that is not practicable to estimate and all non-financial instruments, are excluded from the disclosure requirements. Accordingly, the aggregate estimated fair value amounts presented do not necessarily represent the underlying value of the Company.

The following disclosures represent financial instruments in which the ending balances, as of December 31, 2025 and 2024, were not carried at estimated fair value in their entirety on the consolidated balance sheets.

Cash and Due from Banks and Accrued Interest

The carrying amounts reported in the consolidated balance sheets approximate those assets and liabilities estimated fair values.

Investment Securities, Held-to-Maturity

The fair values of debt securities held-to-maturity are based on quoted market prices for the same or similar securities, recently executed transactions and pricing models.

Loans

For variable-rate loans that reprice frequently and with no significant change in credit risk, estimated fair values are based on carrying values. The estimated fair values of other loans are estimated using discounted cash flow analysis, using interest rates currently being offered for loans with similar terms to borrowers of similar credit quality.

Bank-Owned Life Insurance

Bank-owned life insurance is carried at the amount due upon surrender of the policy, which is also the estimated fair value. This amount was provided by the insurance companies based on the terms of the underlying insurance contract.

Deposits

The estimated fair values of demand deposits are, by definition, equal to the amount payable on demand at the consolidated balance sheet date. The estimated fair values of fixed-rate certificates of deposit are estimated using a discounted cash flow calculation that applies current incremental interest rates being offered on certificates of deposit to a schedule of aggregated expected monthly maturities of the outstanding certificates of deposit.

Short-Term Borrowings and Long-Term Debt

For variable-rate borrowings that reprice frequently, estimated fair values are based on carrying values. The estimated fair values of fixed-rate borrowings are estimated using discounted cash flow analysis, based on the Company’s current incremental borrowing rates for similar types of borrowing arrangements.

Off-Balance Sheet Credit-Related Commitments

Off-balance sheet credit related commitments are generally of short-term nature. The contract amount of such commitments approximates their estimated fair value since the commitments are comprised primarily of unfunded loan commitments which are generally priced at market at the time of funding.

The estimated fair values, and related carrying or notional amounts, of the Company’s financial instruments at the dates indicated are as follows:

	*December 31, 2025*
	*Carrying*		*Estimated Fair Value*

Regulatory Capital Requirements under Banking Regulations [Text Block]

NOTE 26 Regulatory Matters

The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s and the Bank’s consolidated financial statements.

Quantitative measures established by regulation to ensure capital adequacy require the Company and the Bank to maintain minimum amounts and ratios (set forth in the following table) of common equity tier 1, tier 1, and total capital (as defined in the regulations) to risk weighted assets (as defined) and of tier 1 capital (as defined) to average assets (as defined). Management believes at December 31, 2025 and 2024, each of the Company and the Bank met all of the capital adequacy requirements to which it is subject.

As of December 31, 2025, the most recent notification from the FDIC, categorized the Bank as well capitalized under the regulatory framework for prompt corrective action. There are no conditions or events since the notification that management believe have changed in the Bank’s category.

Actual capital amounts and ratios for the Company (consolidated) and the Bank at December 31, 2025 and 2024 are presented in the following table:

Derivative Instruments and Hedging Activities Disclosure [Text Block]

NOTE 25 Derivative Instruments

The Company uses a variety of derivative instruments to mitigate exposure to both market and credit risks inherent in its business activities. The Company manages these risks as part of its overall asset and liability management process and through its policies and procedures. Derivatives represent contracts between parties that usually require little or no initial net investment and result in one party delivering cash or another type of asset to the other party based on a notional amount and an underlying as specified in the contract.

Derivatives are often measured in terms of notional amount, but this amount is generally not exchanged, and it is not recorded on the Company’s consolidated balance sheet. The notional amount is the basis to which the underlying is applied to determine required payments under the derivative contract. The underlying is a referenced interest rate, security price, credit spread, or other index. RRE and CRE loan commitments associated with loans to be sold also qualify as derivative instruments.

Derivatives Designated as Hedging Instruments

The Company uses derivative instruments to hedge its exposure to economic risks, including interest rate, liquidity and credit risk. Certain hedging relationships are formally designated and qualify for hedge accounting under GAAP. On the date the Company enters into a derivative contract designated as a hedging instrument, the derivative is designated as either a fair value hedge, cash flow hedge, or a net investment hedge. When a derivative is designated as a fair value, cash flow, or net investment hedge, the Company performs an assessment, at inception and, at a minimum, quarterly thereafter, to determine the effectiveness of the derivative in offsetting changes in the value or cash flows of the hedged item(s). As of December 31, 2025, the Company only uses fair value and cash flow hedges.

Fair value hedges: These derivatives are interest rate swaps the Company uses to hedge the change in fair value related to interest rate changes of its underlying mortgage-backed investment securities and mortgage loan pools. The interest rate swaps are carried on the Company’s Consolidated Balance Sheet at their fair value in other assets (when the fair value is positive) or in accrued expenses and other liabilities (when the fair value is negative). The changes in fair value of the interest rate swaps are recorded in interest income. The unrealized gains or losses due to changes in fair value of the interest rate swaps due to changes in benchmark interest rates are recorded as an adjustment to the hedged instruments and offset in the same interest income line items.

Cash flow hedges: These derivatives are interest rate swaps the Company uses to hedge the variability of expected future cash flows due to market interest changes. The interest rate swap is carried on the Company’s consolidated balance sheet at its fair value in other assets (when the fair value is positive) or in accrued expenses and other liabilities (when the fair value is negative). Changes in fair value of derivatives designated as cash flow hedges are recorded in OCI until the cash flows of the hedged items are realized. If a derivative designated as a cash flow hedge is terminated or ceases to be highly effective, the gain or loss in OCI is amortized to earnings over the period the forecasted hedged transactions impact earnings. If a hedged forecasted transaction is no longer probable, hedge accounting is ceased and any gain or loss included in OCI is reported in earnings immediately, unless the forecasted transaction is at least reasonably possible of occurring, whereby the amounts remain within accumulated other comprehensive income (loss) (“AOCI”). The Company estimates that no additional amounts will be reclassified to interest expense over the next 12 months. All cash flow hedges were highly effective for the year ended December 31, 2025. As of December 31, 2025, the maximum length of time over which forecasted transactions are hedged is 13 months.

Derivatives Not Designated as Hedging Instruments

Interest rate swaps: The Company periodically enters into commercial loan interest rate swap agreements in order to provide commercial loan customers with the ability to convert from variable to fixed interest rates. These derivative contracts relate to transactions in which the Company enters into an interest rate swap with a customer, while simultaneously entering into an offsetting interest rate swap with an institutional counterparty.

Interest rate lock commitments, forward loan sales commitments and to be announced (TBA) mortgage backed securities: The Company enters into forward delivery contracts to sell mortgage loans at specific prices and dates in order to hedge the interest rate risk in its portfolio of mortgage loans held for sale and its residential mortgage interest rate lock commitments.

The following table presents the total notional amounts and gross fair values of the Company’s derivatives as of December 31, 2025 and 2024:

The Company has third-party agreements that require a minimum dollar transfer amount upon a margin call. This requirement is dependent on certain specified credit measures. The amount of collateral posted with third parties at December 31, 2025 and 2024 was $0.0 million and $3.9 million, respectively. The amount of collateral posted with third parties is deemed to be sufficient to collateralize both the fair market value change a well as any additional amounts that may be required as a result of a change in the specified credit measures.

Credit Risk-Related Contingent Features

By using derivatives, the Company is exposed to credit risk to the extent that counterparties to the derivative contracts do not perform as required. Should a counterparty fail to perform under the terms of a derivative contract, the Company’s credit exposure on interest rate swaps is limited to the net positive fair value and accrued interest of all swaps with each counterparty. The Company seeks to minimize counterparty credit risk through credit approvals, limits, monitoring procedures, and obtaining collateral, where appropriate. As such, management believes the risk of incurring credit losses on derivative contracts with institutional counterparties is remote.

The Company has agreements with its derivative counterparties that contain a provision where, if the Company defaults on any of its indebtedness, including defaults where repayment of the indebtedness has not been accelerated by the lender, the Company could also be declared in default on its derivative obligations. In addition, the Company also has agreements with certain of its derivative counterparties that contain a provision where, if the Company fails to maintain its status as a well-capitalized institution, the counterparty could terminate the derivative position(s) and the Company could be required to settle its obligations under the agreements.

As of December 31, 2025 and 2024, the fair value of derivatives in a net liability position, which included accrued interest but excluded any adjustment for non-performance risk, related to these agreements was $10.6 million and $8.6 million, respectively. As of December 31, 2025 and 2024, the Company had minimum collateral posting thresholds with certain of its derivative counterparties and had posted cash collateral of $0.0 million and $3.9 million, respectively.

Compensation and Employee Benefit Plans [Text Block]

NOTE 18 Employee Benefits

The Company maintains two employee retirement plans including the Alerus Financial Corporation ESOP and a defined contribution salary reduction plan (the “401(k) plan”). The plans cover substantially all employees upon satisfying prescribed eligibility requirements for age and length of service. Contributions to the ESOP are determined annually by the Board, at its discretion, and allocated to participants based on a percentage of annual compensation. For the years ended December 31, 2025, 2024 and 2023, there were no unallocated ESOP shares outstanding. Shares of the Company stock within the ESOP are considered outstanding and dividends on these shares are charged to retained earnings. Under the 401(k) plan, the Company contributes 100% of amounts deferred by employees up to 3% of eligible compensation and 50% of amounts deferred by employees between 3% and 6% of eligible compensation. Retirement plan contributions are reflected under employee benefits in the income statement and for the years ending December 31, 2025, 2024, and 2023 were as follows:

	●	Residential – Junior Lien – National Unemployment; Change in National HPI
	●	Consumer – National Unemployment; Change in National GDP
	●	Paycheck Protection Program – (None)

Credit Concentrations

The Company focuses on maintaining a well-balanced and diversified loan portfolio. Despite such efforts, it is recognized that credit concentrations may occasionally emerge as a result of economic conditions, changes in local demand, natural loan growth and runoff. To identify credit concentrations effectively, all C&I and owner occupied real estate loans are assigned Standard Industrial Classification codes, North American Industry Classification System codes, and state and county codes. Property type coding is used for investment real estate. There were no other industry concentrations exceeding 10% of the Company's total loan portfolio as of December 31, 2025 and 2024.

Credit Quality Indicators

The Company’s consumer loan portfolio is primarily comprised of secured loans that are evaluated at origination on a centralized basis against standardized underwriting criteria. The Company generally does not risk rate consumer loans unless a default event such as bankruptcy or extended nonperformance takes place. Credit quality for the consumer loan portfolio is measured by delinquency rates, nonaccrual amounts and actual losses incurred. These loans are rated as either performing or non-performing.

The Company assigns a risk rating to all commercial loans, except pools of homogeneous loans, and performs detailed internal and external reviews of risk rated loans over a certain threshold to identify credit risks and to assess the overall collectability of the portfolio. These risk ratings are also subject to examination by the Company’s regulators. During the internal reviews, management monitors and analyzes the financial condition of borrowers and guarantors, trends in the industries in which the borrowers operate, completes stress testing of economic factors and evaluates the estimated fair values of collateral securing the loans. These credit quality indicators are used to assign a risk rating to each individual loan.

The Company’s ratings are aligned to pass and criticized categories. The criticized category includes special mention, substandard, and doubtful risk ratings. The risk ratings are defined as follows:

●

Pass: A pass loan is a credit with no existing or known potential weaknesses deserving of management’s close attention.

●

Special Mention: Loans classified as special mention have a potential weakness that deserves management’s close attention. If left uncorrected, this potential weakness may result in deterioration of the repayment prospects for the loan or of the Company’s credit position at some future date. Special mention loans are not adversely classified and do not expose the Company to sufficient risk to warrant adverse classification.

●

Substandard: Loans classified as substandard are not adequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged, if any. Loans classified as substandard have a well-defined weakness or weaknesses that jeopardize the repayment of the debt. Well-defined weaknesses include a borrower’s lack of marketability, inadequate cash flow or collateral support, failure to complete construction on time, or the failure to fulfill economic expectations. They are characterized by the distinct possibility that the Company will sustain some loss if the deficiencies are not corrected.

●

Doubtful: Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or repayment in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable.

●

Loss: Loans classified as loss are considered uncollectible and charged off immediately.

Past Due and Nonaccrual Loans

The Company closely monitors the performance of its loan portfolio. A loan is placed on non-accrual when the financial condition of the borrower is deteriorating, payment in full of both principal and interest is not expected as scheduled or principal or interest has been in default for 90 days or more. Exceptions may be made if the asset is secured by collateral sufficient to satisfy both the principal and accrued interest in full and collection is reasonably assured. When one loan to a borrower is placed on non-accrual, all other loans to the borrower are re-evaluated to determine if they should also be placed on non-accrual. All previously accrued and unpaid interest is reversed at that time. A loan will return to accrual when collection of principal and interest is assured and the borrower has demonstrated timely payments of principal and interest for a reasonable period, generally at least six months.

The following tables present past due aging analysis of total loans outstanding, by portfolio segment, as of December 31, 2025 and 2024, respectively:

Interest income that would have been recognized if loans on nonaccrual status had been current in accordance with their original terms for the years ended December 31, 2025, 2024, and 2023 is estimated to have been $3.3 million, $4.8 million, and $0.5 million, respectively.

The Company’s policy is to reverse previously recorded interest income when a loan is placed on nonaccrual. As a result, the Company did not record any interest income on its nonaccrual loans for the years ended years ended December 31, 2025, 2024 and 2023. As of December 31, 2025 and 2024, total accrued interest receivable on loans, which had been excluded from reported amortized cost basis on loans, was $18.1 million and $16.4 million, respectively, and was reported within accrued interest receivable on the consolidated balance sheets. An allowance was not carried on the accrued interest receivable at either date.

The following tables present the amortized cost basis of collateral dependent loans, by the primary collateral type, which are individually evaluated to determine credit losses, and the related ACL allocated to these loans, as of December 31, 2025 and 2024:

Collateral dependent loans are loans for which the repayment is expected to be provided substantially by the underlying collateral and there are no other available and reliable sources of repayment.

Loan Modifications to Borrowers Experiencing Financial Difficulty

Effective January 1, 2023, the Company evaluates all loan modifications in accordance with ASU 2022-02. Under ASU 2022-02, a loan is evaluated to consider whether the loan, as modified, represents a new loan or is a continuation of an existing loan.

In cases where a borrower experiences financial difficulty, the Company may make certain concessions for which the terms of the loan are modified with the intention to minimize future losses and improve collectability. Loans experiencing financial difficulty can include modifications for an interest rate reduction below current market rates, a forgiveness of principal balance, an extension of the loan term, an-other than significant payment delay, or some combination of similar types of modifications.

The following tables present the amortized cost basis of loans as of December 31, 2025 and 2024, respectively, by type of modification, that were both experiencing financial difficulty and modified during the years ended December 31, 2025 and 2024. The percentage of the amortized cost basis of loans that were modified to borrowers in financial distress as compared to the amortized cost basis of each class of financing receivable as of December 31, 2025 and 2024 is also presented in the tables below:

The adequacy of the ACL on investment securities is assessed at the end of each quarter. The Company does not believe that the AFS debt securities that were in an unrealized loss position as of December 31, 2025 represent a credit loss impairment. As of both December 31, 2025 and 2024, the gross unrealized loss positions were primarily related to mortgage-backed securities issued by U.S. government agencies or U.S. government-sponsored enterprises. These securities carry the explicit and/or implicit guarantee of the U.S. government, are widely recognized as “risk free,” and have a long history of zero credit loss. Additionally, there were corporate bonds in gross unrealized loss positions; however, all bonds had an investment grade rating as of both December 31, 2025 and 2024. Total gross unrealized losses were attributable to changes in interest rates, relative to when the investment securities were purchased, and not due to the credit quality of the investment securities. The Company does not intend to sell the investment securities that were in an unrealized loss position and it is not more likely than not that the Company will be required to sell the investment securities before recovery of their amortized cost basis, which may be at maturity.

The ACL on HTM debt securities is estimated using relevant information, from internal and external sources, relating to past events, current conditions, and reasonable supportable forecasts. Using a probability of default and loss given default analysis, an ACL was established in the amount of $123 thousand and $131 thousand as of December 31, 2025 and 2024, respectively.

Accrued interest receivable on AFS investment securities and HTM investment securities is recorded in accrued interest receivable and is excluded from the estimate of credit losses. As of December 31, 2025, the accrued interest receivable on AFS investment securities and HTM investment securities totaled $1.9 million and $1.2 million, respectively. As of December 31, 2024, the accrued interest receivable on AFS investment securities and HTM investment securities totaled $2.0 million and $1.3 million, respectively.

Proceeds from the sale of AFS securities for the years ended December 31, 2025, 2024, and 2023 are displayed in the table below:

Investment securities with a total carrying value of $115.1 million and $340.2 million, were pledged at December 31, 2025 and 2024, respectively, to secure public deposits and for other purposes required or permitted by law.

As of December 31, 2025 and 2024, the carrying value of the Company’s Federal Reserve Bank stock and FHLB of Des Moines stock was as follows:

	*December 31,*		*December 31,*
(dollars in thousands)	*2025*		*2024*
Federal Reserve	$	8,631	$	7,519
FHLB		17,968		13,656

These securities can only be redeemed or sold at their par value and only to the respective issuing institution or to another member institution. The Company records these non-marketable equity securities as a component of other assets and periodically evaluates these securities for impairment. Management considers these non-marketable equity securities to be long-term investments. Accordingly, when evaluating these securities for impairment, management considers the ultimate recoverability of the par value rather than recognizing temporary declines in value.

Visa Class B Restricted Shares

In 2008, the Company received Visa Class B restricted shares as part of Visa’s initial public offering. These shares are transferable only under limited circumstances until they can be converted into the publicly traded Class A common shares. This conversion will not occur until the settlement of certain litigation which will be indemnified by Visa members, including the Company. Visa funded an escrow account from its initial public offering to settle these litigation claims. Should this escrow account be insufficient to cover these litigation claims, Visa is entitled to fund additional amounts to the escrow account by reducing each member bank’s Class B conversion ratio to unrestricted Class A shares. As of December 31, 2025, the conversion ratio was 1.5491. Based on the existing transfer restriction and the uncertainty of the outcome of the Visa litigation mentioned above, the 6,924 Class B shares (10,726 Class A equivalents) that the Company owned as of December 31, 2025 and 2024, were carried at a zero cost basis.

Note 9 - Loan Servicing

12 Months Ended

Dec. 31, 2025

Transfers and Servicing of Financial Assets [Text Block]

NOTE 9 Loan Servicing

Loans serviced for others are not included in the accompanying consolidated balance sheets. The unpaid principal balances of loans serviced for others totaled $660.7 million and $728.5 million at December 31, 2025 and 2024, respectively. Servicing loans for others generally consists of collecting mortgage payments, maintaining escrow accounts, disbursing payments to investors and collection and foreclosure processing. Loan servicing income is recorded on an accrual basis and includes servicing fees from investors and certain charges collected from borrowers, such as late payment fees, and is net of fair value adjustments to capitalized mortgage servicing rights. As of and for the years ended December 31, 2025 and 2024, the Company elected to subsequently measure MSRs at fair value. The Company accounted for MSRs at the lower of amortized cost or fair value as of and for the years ended December 31, 2023.

The following table presents the changes in fair value of the Company’s MSR portfolio for the years ended December 31, 2025 and 2024:

	*Year ended*
	*December 31,*
(dollars in thousands)	*2025*			*2024*
Balance at beginning of period	$	7,918		$	2,052
Servicing assets acquired in business combination		—			5,445
Additions from loans sold with servicing rights retained		165			224
Change in fair value		(1,700	)		197
Balance at end of period	$	6,383		$	7,918

The following table summarizes the Company’s activity related to servicing rights for the years ended December 31, 2023:

(dollars in thousands)	2023
Servicing Assets:
Balance at beginning of period	$	2,643
Additions, net of valuation reserve ⁽¹⁾		300
Amortization ⁽²⁾		(595	)
Balance at end of period		2,348
Less valuation reserve ⁽³⁾		(296	)
Balance at end of period, net of valuation reserve	$	2,052
Fair value, beginning of period	$	2,314
Fair value, end of period	$	2,062

⁽¹⁾	Associated income was reported within mortgage banking income, net on the consolidated statements of income.

⁽²⁾	Associated amortization expense was reported within other noninterest income on the consolidated statements of income.

⁽³⁾	Associated valuation reserve was reported within mortgage and lending expenses on the consolidated statements of income.

The following is a summary of key data and assumptions used in the valuation of servicing rights as of December 31, 2025 and 2024. Increases or decreases in any one of these assumptions would result in lower or higher fair value measurements.

	*December 31,*			*December 31,*
(dollars in thousands)	*2025*			*2024*
Fair value of servicing rights	$	6,383		$	7,918
Weighted-average remaining term, years	21.5				22.0
Prepayment speeds		14.4	%		9.9	%
Discount rate		10.0	%		10.5	%

The entire disclosure for a transferor's continuing involvement in financial assets that it has transferred in a securitization or asset-backed financing arrangement, the nature of any restrictions on assets reported by an entity in its statement of financial position that relate to a transferred financial asset (including the carrying amounts of such assets), how servicing assets and servicing liabilities are reported, and (for securitization or asset-backed financing arrangements accounted for as sales) when a transferor has continuing involvement with the transferred financial assets and transfers of financial assets accounted for as secured borrowings, how the transfer of financial assets affects an entity's financial position, financial performance, and cash flows.

The Company adopted ASU 2023-09 "Income Taxes (Topic 740): Improvements to Income Tax Disclosures" on a prospective basis beginning with the year ended December 31, 2025. A reconciliation of income tax expense at the U.S. federal statutory rate (21% in 2025) to the Company's actual income tax expense for the year ended December 31, 2025 is shown below.

	*Year Ended*
	*December 31, 2025*

Accounting Standards Update and Change in Accounting Principle [Text Block]

NOTE 2 New Accounting Pronouncements

The following FASB ASUs are divided into pronouncements which have been adopted by the Company since January 1, 2023, and those which are not yet effective and have been evaluated or are currently being evaluated by management, as of December 31, 2025.

Adopted Pronouncements

In November 2023, the FASB issued guidance within ASU 2023-07, Segment Reporting (Topic 280). The amendments in this update are intended to improve reportable segment disclosure requirements, primarily through enhanced disclosures related to significant segment expenses. The amendments do not change how an entity identifies its operating segments, aggregates those operating segments, or applies the quantitative thresholds to determine its reportable segments, and all existing segment disclosure requirements in ASC 280 and other Codification topics remain unchanged. The amendments in this update are incremental and require public entities that report segment information to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss as well as other segment items. Annual disclosure of the title and position of the chief operating decision maker and how the reported measures of segment profit or loss are used to assess performance and allocation of resources is also required.

The amendments in this update are effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, and are applied on a retrospective basis. The Company adopted this ASU retrospectively as of and for the year ended December 31, 2024.

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The amendments in this ASU related to the rate reconciliation and income taxes paid disclosures improve the transparency of income tax disclosures by requiring consistent categories and greater disaggregation of information in the rate reconciliation and income taxes paid disaggregated by jurisdiction. The amendments allow investors to better assess, in their capital allocation decisions, how an entity’s worldwide operations and related tax risks and tax planning and operational opportunities affect its income tax rate and prospects for future cash flows. The other amendments in this Update improve the effectiveness and comparability of disclosures by adding disclosures of pretax income (or loss) and income tax expense (or benefit) to be consistent with U.S. Securities and Exchange Commission (SEC) Regulation S-X 210.4-08(h), Rules of General Application—General Notes to Financial Statements: Income Tax Expense, and removing disclosures that no longer are considered cost beneficial or relevant. For public business entities, the amendments in this ASU are effective for annual periods beginning after December 15, 2024. For entities other than public business entities, the amendments are effective for annual periods beginning after December 15, 2025. The amendments in this Update were applied on a prospective basis and did not have an impact on the Company's consolidated financial statements.

Pronouncements Not Yet Effective

In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting. These amendments provide temporary optional guidance to ease the potential burden in accounting for reference rate reform. The ASU provides optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that the London Interbank Offered Rate (“LIBOR”) reference or another reference rate expected to be discontinued. It is intended to help stakeholders during the global market-wide reference rate transition period. The guidance is effective for all entities as of March 12, 2020, through December 31, 2022. In January 2021, the FASB issued ASU 2021-01. Reference Rate Reform (Topic 848) in response to concerns about structural risks in accounting for reference rate reform. The ASU clarifies certain optional expedients and exceptions in Topic 848 for contract modifications and hedge accounting apply to derivatives that affected by the discontinuing transition. LIBOR is used as an index rate for a portion of the Company’s available-for-sale securities, derivative contracts, subordinated notes payable, junior subordinated debentures, and approximately 2.1% of the Company’s loans, as of December 31, 2025.

If reference rates are discontinued, the existing contracts will be modified to replace the discounted rate with a replacement rate. For accounting purposes, such contract modifications would have to be evaluated to determine whether the modified contract is a new contract or a continuation of an existing contract. If they are considered new contracts, the previous contract would be extinguished. Under one of the optional expedients of ASU 2020-04, modifications of contracts within the scope of Topic 310, receivables, and 470, Debt, will be accounted for by prospectively adjusting the effective interest rates and no such evaluation is required. When elected, the optional expedient for contract modifications must be applied consistently for all eligible contracts or eligible transactions. The Company is in the process of evaluating the impact of this pronouncement of those financial assets and liabilities where LIBOR is used as an index rate.

In December 2022, the FASB issued ASU 2022-06 Reference Rate Reform (Topic 848) Deferral of the Sunset Date of Topic 848. This amendment provides an update to defer the sunset date of Topic 848 from December 31, 2022, to December 31, 2024, after which all entities will no longer be permitted to apply the relief in Topic 848.

In November 2025, the FASB issued ASU 2025-08, Financial Instruments - Credit Losses (Topic 326): Purchased Loans. The amendments in this update are intended to improve decision usefulness and comparability of financial reporting for acquired financial assets while retaining the measurement, presentation or disclosure requirements outlined in ASC 326. The update introduces the concept of “purchased seasoned loans,” which refers to non-PCD loans acquired in a business combination or in an asset acquisition more than 90 days after their origination date. The amendments align the accounting for purchased seasoned loans with the gross-up methodology applied to PCD loans, whereby the initial estimate of credit losses is amortized over the life of the loan as a reduction to interest income, rather than being recognized immediately in earnings as credit loss expense. The update also includes an accounting policy election related to the subsequent measurement of expected credit losses on purchased seasoned loans for entities using a method other than a discounted cash flow analysis. Under this election, entities may use the amortized cost basis of the asset, rather than the unpaid principal balance to estimate credit losses on these loans.

The amendments in this update are effective for fiscal years beginning after December 15, 2026 and interim periods within those fiscal years. The amendments are to be applied prospectively, and early adoption is permitted. The Company is currently evaluating the impact these amendments may have on its consolidated financial statements.

The entire disclosure for change in accounting principle. Includes, but is not limited to, nature, reason, and method of adopting amendment to accounting standards or other change in accounting principle.

Cybersecurity Risk Management, Strategy, and Governance [Line Items]

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]

Risk Management and Strategy. The Company relies extensively on various information systems and other electronic resources to operate its business. In addition, nearly all of the Company’s customers, service providers and other business partners on whom the Company depends, including the providers of the Company’s online banking, mobile banking and accounting systems, use these systems and their own electronic information systems. Any of these systems can be compromised, including by employees, customers and other individuals who are authorized to use them, and bad actors using sophisticated and constantly evolving set of software, tools and strategies to do so. The nature of the Company’s business, as a financial services provider, and the Company’s relative size, make the Company and its business partners high-value targets for these bad actors to pursue. See Item 1A. Risk Factors—Operational, Strategic and Reputational Risks of this Form 10-K for additional information.

Accordingly, the Company has devoted significant resources to assessing, identifying and managing risks associated with cybersecurity threats, as noted below:

●

Identifying and assessing cybersecurity threats: The Company regularly evaluates its systems and data for potential vulnerabilities and analyzes the evolving cyber threat landscape, to ensure it proactively addresses risks before they materialize. The Company employs monitoring tools that can detect and help respond to cybersecurity threats in real-time.

●

Integration with Overall Risk Management: Cybersecurity risks are seamlessly integrated into the Company’s broader risk management framework, ensuring a holistic view and prioritized mitigation strategies.

●

Management of Third-Party Risk: The Company’s comprehensive third-party management process includes rigorous due diligence, oversight and identification of cybersecurity risks associated with vendors and service providers.

●

Team: The Company has an internal cybersecurity team that is responsible for conducting regular assessments of its information systems, existing controls, vulnerabilities and potential improvements.

●

Engagement of Expert Assistance: The Company leverages the expertise of independent consultants, legal advisors, and audit firms to evaluate the effectiveness of our risk management systems and address potential cybersecurity incidents efficiently.

●

Training: The Company conducts periodic cybersecurity training for its workforce.

This information security program is a key part of the Company’s overall risk management system, which is administered by the Director of Information Security. The program includes administrative, technical and physical safeguards to help protect the security and confidentiality of customer records and information. These security and privacy policies and procedures are in effect across all of the Company’s businesses and geographic locations.

From time-to-time, the Company has identified minor cybersecurity threats and cybersecurity incidents that require the Company to make changes to its processes and to implement additional safeguards. While none of these identified threats or incidents have materially affected the Company, it is possible that threats and incidents the Company identifies in the future could have a material adverse effect on its business strategy, results of operations and financial condition.

Governance. The Company’s management team is responsible for the day-to-day management of cybersecurity risks it faces, including the Company’s Executive Vice President and Chief Operating Officer and Director of Information Security. The Company’s current Director of Information Security has over 30 years of experience. For the past 9 years, the Company’s Director of Information Security has successfully managed teams, implementing and maintaining robust cybersecurity and data protection controls to safeguard the Company’s information assets. The Company’s Director of Information Security reports directly to our Executive Vice President and Chief Operating Officer, who possesses extensive expertise gained through over 30 years in various risk, operations and leadership roles. This combined experience ensures exceptional guidance and oversight of our cybersecurity program.

In addition, the Board, both as a whole and through its Risk Committee (the “Risk Committee”), is responsible for the oversight of risk management, including cybersecurity risks. In that role, the Board and the Risk Committee, with support from the Company’s cybersecurity advisors, are responsible for ensuring that the risk management processes designed and implemented by management are adequate and functioning as designed. To carry out those duties, both the Board and the Risk Committee receive quarterly reports from the Company’s management team regarding cybersecurity risks and the Company’s efforts to prevent, detect, mitigate and remediate any cybersecurity incidents.
