MARATHON BANCORP, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Unaudited

Note 1- Basis of Presentation

Marathon Bancorp, Inc. (the “Company” or “Marathon Bancorp”), a Maryland corporation, was formed in December 2020 to serve as the mid-tier holding company for Marathon Bank (the “Bank”) upon the completion of the Bank’s mutual holding company reorganization and offering.

On April 14, 2021, the Bank completed its reorganization into the mutual holding company structure and the related stock offering of the Company, the Bank’s new holding company. As a result of the reorganization, the Bank became a wholly-owned subsidiary of the Company, the Company issued and sold 45.0% of its outstanding shares of common stock in its stock offering to the public, and the Company issued 55.0% of its outstanding shares of common stock to Marathon MHC (“Mutual Holding Company”), which was the Company’s mutual holding company.

On April 21, 2025, the Company completed its conversion from the mutual holding company form of organization to the stock holding company form of organization (the "Conversion"). In connection with the Conversion, the Mutual Holding Company ceased to exist. Also, as part of the Conversion, the Company sold 1,693,411 shares of its common stock, which included 135,472 shares issued to the Employee Stock Ownership Plan (“ESOP”) at a price of $10.00 per share to the public. Each outstanding share of Company common stock owned by the public stockholders of the Company (stockholders other than the Mutual Holding Company) were converted into new shares of Company common stock based on an exchange ratio of 1.3728-to-1. Following the completion of the Conversion, the Company’s shares of common stock began trading on the Nasdaq Capital Market under the trading symbol “MBBC.”

​

The Company generated gross proceeds of $16.9 million from the Conversion. Offering expenses in connection with the Conversion were $1.7 million which were netted against the gross proceeds.

​

In connection with the Conversion, the Company provided a term loan to the ESOP to finance the ESOP’s purchase of the 135,472 shares noted above. The Company combined its existing outstanding ESOP loan in the amount of $777,212 with this new loan resulting in a new term loan to the ESOP of $2.1 million which will be repaid in annual installments over 25 years.

​

Finally, as a result of the Conversion, all existing stock options and restricted stock awards outstanding on April 21, 2025 were adjusted based on the exchange ratio of 1.3728-to-1. All historical share and per share information also has been restated to reflect the 1.3728-to-1 exchange ratio.

​

The Bank is a Wisconsin stock savings bank, which conducts its business through five facilities. The Bank operates as a full-service financial institution with a primary market area including, but not limited to, Marathon County, Ozaukee County and Waukesha County, Wisconsin. Its primary deposit products are demand deposits, savings, and certificates of deposits; and its primary lending products are commercial real estate, commercial and industrial, construction, one-to-four-family residential, multi-family real estate and consumer loans. In addition, the Bank has two nonbank subsidiaries for the purpose of temporarily holding a foreclosed property pending the liquidation of this property and to hold the real estate of its recently opened branch in Brookfield, Wisconsin.

​

The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial information. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes. Actual results may differ from those estimates, and such differences could be material to the financial statements. Material estimates that are particularly susceptible to significant changes in the near term relate to the determination of the allowance for credit losses, valuation of foreclosed assets, valuation of deferred tax assets, and fair value of financial assets and liabilities.

In the opinion of management, all adjustments considered necessary for fair presentation have been included. Operating results for the three month period ended September 30, 2025 are not necessarily indicative of the results for the year ending June 30, 2026 or any other period. For further information, refer to the audited consolidated financial statements and notes thereto for the years ended June 30, 2025 and 2024 contained in the Company’s Annual Report on Form 10-K as filed with the Securities and Exchange Commission on September 26, 2025.

Recent Accounting Pronouncements

​

This section provides a summary description of recent Accounting Standards Updates (ASU) issued by the Financial Accounting Standards Board (FASB) to the Accounting Standards Codification (ASC) that had or that management expects may have an impact on the consolidated financial statements issued upon adoption. The Company is classified as an emerging growth company and has elected to use the extended transition period for complying with any new or revised financial accounting standards provided pursuant to Section 13(a) of the Exchange Act. Effective dates reflect this election.

​

Recently Issued, But Not Yet Effective Accounting Pronouncements

In November 2024, the Financial Accounting Standards Board (FASB) issued ASU 2024-03, “Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses.” ASU 2024-03 requires public companies to disclose, in the notes to the financial statements, specific information about certain costs and expenses at each interim and annual reporting period. This includes disclosing amounts related to employee compensation, depreciation, and intangible asset amortization. In addition, public companies will need to provide qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively. In January 2025, the FASB issued ASU No. 2025-01 clarifying the effective date for public business entities for fiscal years beginning after December 15, 2026 and interim periods within annual reporting periods beginning after December 15, 2027. Early adoption is permitted. The Company is evaluating ASU 2024-03 and its impact on its disclosures.

​

In December 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures.” The amendments in this ASU require an entity to disclose specific categories in the rate reconciliation and provide additional information for reconciling items that meet a quantitative threshold, which is greater than five percent of the amount computed by multiplying pretax income by the entity’s applicable statutory rate, on an annual basis. Additionally, the amendments in this ASU require an entity to disclose the amount of income taxes paid (net of refunds received) disaggregated by federal, state, and foreign taxes and the amount of income taxes paid (net of refunds received) disaggregated by individual jurisdictions that are equal to or greater than five percent of total income taxes paid (net of refunds received). Lastly, the amendments in this ASU require an entity to disclose income (or loss) from continuing operations before income tax expense (or benefit) disaggregated between domestic and foreign and income tax expense (or benefit) from continuing operations disaggregated by federal, state, and foreign. This ASU is effective for annual periods beginning after December 15, 2024. Early adoption is permitted. The amendments should be applied on a prospective basis; however, retrospective application is permitted. The Company does not expect the adoption of ASU 2023-09 to have a material impact on its consolidated financial statements.

Note 2- Earnings Per Share

Basic net income per common share is calculated by dividing net income by the weighted-average number of common shares outstanding during the period. Unallocated common shares held by the ESOP are not included in the weighted-average number of common shares outstanding for purposes of calculating earnings per common share until they are committed to be released. Diluted earnings per share is adjusted for the dilutive effects of stock based compensation and is calculated using the treasury stock method. Set forth below is the calculation of earnings per share.

​

There is no allowance for credit losses on available for sale and held to maturity debt securities at September 30, 2025 and June 30, 2025. Securities with a carrying value of approximately $53,000 and $79,000 as of September 30, 2025 and June 30, 2025, respectively, were pledged to secure public deposits and debt. Accrued interest receivable totaled $50,715 and $64,377 as of September 30, 2025 and June 30, 2025, respectively and is excluded from the measurement of credit losses.

The amortized cost and fair value of debt securities by contractual maturity at September 30, 2025, follows:

There were also no transfers of debt securities between categories during the three month periods ended September 30, 2025 and 2024. The following table shows the gross unrealized losses and fair value of the Company’s securities for which an allowance for credit losses has not been recorded, aggregated by investment category and length of time that individual securities have been in a continuous unrealized loss position at September 30, 2025 and June 30, 2025:

​

There was one security in an unrealized loss position in the less than 12 months category and 36 securities in the 12 months or more category at September 30, 2025. There were four securities in an unrealized loss position in the less than 12 months category and 40 securities in the 12 months or more category at June 30, 2025. Unrealized losses have not been recognized into income because the decline in fair value is largely due to changes in interest rates and other market conditions. The contractual terms of the securities do not permit the issuer to settle the securities at a price less than the amortized cost basis of the investment. The Company does not intend to sell the securities and it is not more likely than not that the Company will be required to sell the securities before recovery of their amortized cost bases, which may be maturity. Mortgage-backed securities held to maturity are backed by pools of mortgages that are insured or guaranteed by the Federal Home Mortgage Corporation. It is expected that the securities will not be settled at prices less than the amortized cost bases of the securities. Accordingly, no allowance for credit losses has been recorded.

Note 4- Loans

The Company’s loans are stated at their face amount, net of deferred fees and costs and discounts, and consist of the classes of loans included in the table below. The Company has elected to exclude accrued interest receivable, totaling $649,927 at September 30, 2025 and $603,309 as of June 30, 2025, from the amortized cost basis of loans.

Credit Quality Indicators

The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, collateral adequacy, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis typically includes larger, non-homogeneous loans such as commercial and industrial, commercial real estate loans and multi-family real estate loans. This analysis is performed on an ongoing basis as new information is obtained. The Company uses the following definitions for risk ratings:

Pass – Loans classified as pass represent loans that are evaluated and are performing under the stated terms. Pass rated assets are analyzed by the paying capacity, the current net worth, and the value of the loan collateral of the obligor.

Watch - A watch grade is assigned to any credit that is adequately secured and performing but monitored for a number of indicators. These characteristics may include, but are not limited to: any unexpected short-term adverse financial performance from budgeted projections or prior period results (i.e., declining profits, sales, margins, cash flow, or increased reliance on leverage, including adverse balance sheet ratios, trade debt issues, etc.), any managerial or personal problems of company management, a decline in the entire industry or local economic conditions, failure to provide financial information or other documentation as requested, issues regarding delinquency, overdrafts, or renewals, and any other issues that cause concern for the Company.

Special Mention – The characteristics of a special mention asset have potential weaknesses that deserve the Company’s close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the asset or in the institution’s credit position at some future date. Special mention assets are considered criticized assets. Characteristics of special mention loans may include: continued adverse financial trends relating to declining sales, profits, margins, balance sheet ratios, increasing debt to worth, and trade debt issues; cash flows declining in coverage, a repeated lack of compliance with Bank requests for information, correction of a violation of loan covenants, lack of current or adequate financial information or documentation, or more serious managerial or declining industry conditions. Weakness identified in a special mention credit should be short-term in nature.

Substandard – Loans classified as substandard are inadequately protected by the current net worth, paying capacity of the obligor, or by the collateral pledged. Substandard loans must have a well-defined weakness or weaknesses that jeopardize the repayment of the debt as originally contracted. They are characterized by the distinct possibility that the Company will sustain a loss if the deficiencies are not corrected.

Doubtful – Loans classified as doubtful have the weaknesses of those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans in this category are individually evaluated for impairment or charged-off if deemed uncollectible.

Residential real estate and consumer loans are managed on a pool basis due to their homogeneous nature. Loans that are 90 days or more delinquent or are not accruing interest are considered nonperforming.

Note 5 - Leases

Lease liabilities represent the Company’s obligation to make lease payments and are presented at each reporting date as the net present value of the remaining contractual cash flows. Cash flows are discounted at the Company’s incremental borrowing rate in effect at the commencement date of the lease. Right-of-use assets represent the Company’s right to use the underlying asset for the lease term and are calculated as the sum of the lease liability and if applicable prepaid rent, initial direct costs and any incentives received from the lessor.

The Company’s long-term lease agreements are classified as operating leases. Certain of these leases offer the option to extend the lease term and the Company has included such extensions in its calculation of the lease liabilities to the extent the options are reasonably assured of being exercised. The lease agreements do not provide for residual value guarantees and have no restrictions or covenants that would impact dividends or require incurring additional financial obligations.

The following tables present information about the Company’s leases as of and for the three months ended September 30, 2025 and 2024 and as of June 30, 2025:

Note 10- Minimum Regulatory Capital Requirements

Bank regulatory authorities in the United States issue risk-based capital standards. These capital standards relate a banking company’s capital to the risk profile of its assets and provide the basis by which all banking companies and banks are evaluated in terms of capital adequacy.

The risk-based capital standards require financial institutions to maintain: (a) a minimum ratio of common equity tier 1 (“CET1”) to risk weighted assets of at least 4.5%, (b) a minimum ratio of tier 1 capital to risk-weighted assets of at least 6.0%; (c) a minimum ratio of total (that is, tier 1 plus tier 2) capital to risk-weighted assets of at least 8.0%; and (d) a minimum leverage ratio of 3.0%, calculated as the ratio of tier 1 capital balance sheet exposures plus certain off-balance sheet exposures (computed as the average for each quarter of the month-end ratios for the quarter). In addition, the rules also limit a banking organization’s capital distributions and certain discretionary bonus payments if the banking organization does not hold a “capital conservation buffer” of 2.5% above the minimum standards stated in (a) - (c) above.

In September 2019, the FDIC finalized a rule to simplify the capital calculation for qualifying community banking organizations (i.e., the community bank leverage ratio (“CBLR”)), as required by the Economic Growth, Regulatory Relief and Consumer Protection Act. The CBLR framework is designed to reduce burden by removing the requirements for calculating and reporting risk-based capital ratios for qualifying community banking organizations that opt into the framework. A qualifying community bank may elect to utilize the CBLR in lieu of the general capital requirements and will be considered well capitalized if it exceeds the minimum CBLR of 9.0%. The CBLR framework also provides a two-quarter grace period for qualifying banks whose leverage ratio falls no more than 1.00% below the required ratio for that reporting quarter. The Bank opted into the CBLR framework as of September 30, 2025 and June 30, 2025.

As of September 30, 2025 and June 30, 2025, management believes the Bank has met all capital adequacy requirements to which it is subject. As of September 30, 2025 and June 30, 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 believes have changed the Bank’s category.

The Bank’s actual capital amounts and ratios are presented in the following table (dollars in thousands):

Note 11 - Employee Benefit Plans

The Company provides a 401(k) salary deferral plan to substantially all employees. Employees are allowed to make voluntary contributions to the plan up to 15% of their compensation. In addition, the Company provides discretionary matching and profit-sharing contributions as well as a safe harbor contribution.

Effective upon the completion of the Company’s initial public stock offering in April 2021, the Company established an Employee Stock Ownership Plan (“ESOP”) for all eligible employees. The ESOP used $873,970 in proceeds from a term loan obtained from the Company to purchase 87,397 shares of common stock in the initial public offering at a price of $10.00 per share. Also, as part of the Conversion, the Company sold 135,472 shares of its common stock to the ESOP at a price of $10.00 per share. The outstanding balance of the April 2021 ESOP loan ($777,212 and the new ESOP loan $1,354,720) were combined as of the date of the Conversion. The new ESOP loan will be repaid principally from the Company’s contribution to the ESOP in annual payments through 2049 at a variable interest rate at the Bank’s prime rate. Shares are released to participants on a straight-line basis over the loan term and allocated based on participant compensation. The Company recognizes compensation benefit expense as shares are committed for release at their current market price. The difference between the market price and the cost of shares committed to be released is recorded as an adjustment to additional paid-in capital. Dividends on allocated shares, if applicable, are recorded as a reduction of retained earnings and dividends on unallocated shares are recorded as a reduction of debt. The Company recognized $35,438 (upon the release of 2,363 shares) and $10,487 (upon the release of 874 shares) of compensation expense related to this plan for the three months ended September 30, 2025 and 2024. At September 30, 2025, there were 229,165 shares not yet released having an aggregate market value of approximately $2,390,191. Participants will become fully vested upon completion of three years of credited service. Eligible employees who were employed with the Company shall receive credit for vesting purposes for each year of continuous employment prior to adoption of the ESOP.

​

Note 12 - Stock Based Compensation

On May 24, 2022, the stockholders of Marathon Bancorp, Inc. approved the Company’s 2022 Equity Incentive Plan (the “Plan”), which provides for the grant of stock-based awards to officers, employees and directors of the Company and Marathon Bank. Under provisions of the Plan, while active, awards may consist of grants of incentive stock options, nonqualified stock options, restricted stock and restricted stock units. Incentive stock options totaling 149,972 and restricted stock awards totaling 59,989 were authorized for award under the Plan. As a result of the Conversion, all existing stock options and restricted stock awards outstanding on April 21, 2025 were adjusted based on the exchange ratio of 1.3728-to-1 including those described below. The grant date exercise prices for stock options and fair values of restricted stock at grant date were adjusted downward based on the exchange ratio.

​

​

Stock Options

On June 28, 2022, a total of 100,481 stock option awards were granted to the Bank’s directors, executive officers, senior officers and other officers (25,496 and 74,985 options were awarded to directors and employees, respectively). Director awards are considered non-qualified stock options while employee awards are considered incentive stock options. During the year ended June 30, 2023, a director and employee retired resulting in the forfeiture of 10,498 options. An additional 3,996 of options were forfeited by an employee during the year ended June 30, 2025. The awards vest ratably over five years (20% per year for each year of the participant’s service with the Company) and will expire ten years from the date of the grant, or June 2032. The fair value of each option grant was established at the date of grant using the Black-Scholes option pricing model. The Black-Scholes model used the following weighted average assumptions: risk-free interest rate of 3.27%; volatility factors of the expected market price of the Company's common stock of 20.76%; weighted average expected lives of the options of 6.5 years; cash dividend yield of 0%. The expected term of the options is derived by using the simplified method as the Company has no relevant exercise experience from other stock-based compensation plans. Based upon these assumptions, the weighted average fair value of options granted was $3.33.

Table of Contents

On May 16, 2023, a total of 53,992 stock option awards were granted to the Bank’s directors, executive officers, senior officers and other officers (5,996 and 47,996 options were awarded to directors and employees, respectively). The fair value of each option grant was established at the date of grant using the Black-Scholes option pricing model. The Black-Scholes model used the following weighted average assumptions: risk-free interest rate of 3.53%; volatility factors of the expected market price of the Company's common stock of 20.71%; weighted average expected lives of the options of 6.5 years; cash dividend yield of 0%. The expected term of the options is derived by using the simplified method as the Company has no relevant exercise experience from other stock-based compensation plans. Based upon these assumptions, the weighted average fair value of options granted was $2.72.

Stock option expense amortized to expense for the three months ended September 30, 2025 and 2024 was $15,827 and $16,262, respectively. At June 30, 2025, total unrecognized compensation expense related to stock options was $133,265, and will be amortized to expense over a period of 2.3 years. On June 28, 2025, there were 5,996 stock option awards granted to two employees. As of September 30, 2025, no future stock option awards remain under the Plan.

The aggregate intrinsic value of a stock option represents the total pre-tax intrinsic value (the amount by which the current market value of the underlying stock exceeds the exercise price of the option) that would have been received by the option holders had all option holders exercised their options prior to the expiration date. The intrinsic value can change based on fluctuations in the market value of the Company’s stock.

A summary of stock option activity and related information for the three months ended September 30, 2025 and 2024 is as follows.

Note 13- Commitments and Contingencies

The Company is a party to credit-related financial instruments with off-balance-sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amount recognized in the balance sheet. The Company’s exposure to credit loss is represented by the contractual amount of these commitments. The Company uses the same credit policies in making commitments as it does for on-balance-sheet instruments.

As of September 30, 2025 and June 30, 2025, the following financial instruments were outstanding where contract amounts represent credit risk:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | September 30, 2025 |  | June 30, 2025
Commitments to grant loans | ​ | $ | 1,166,000 | ​ | $ | 4,790,000
Unused commitments under lines of credit | ​ |  | 6,333,272 | ​ |  | 6,346,008
MPF credit enhancements | ​ |  | 765,822 | ​ |  | 735,448

​

Commitments to grant loans are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The commitments for equity lines of credit may expire without being drawn upon. Therefore, the total commitment amounts do not necessarily represent future cash requirements. The amount of collateral obtained, if it is deemed necessary by the Company, is based on management’s credit evaluation of the customer.

Mortgage Partnership Finance (MPF) credit enhancements allow the Company to share the credit risk associated with home mortgage finance with Federal Home Loan Bank (FHLB). MPF provides the Company the ability to originate, sell, and service fixed-rate, residential mortgage loans, and receive a Credit Enhancement Fee based on the performance of the loans. FHLB manages the liquidity, interest rate, and prepayment risks of the loans while the Company manages the credit risk of the loans. The Company will incur an obligation on a foreclosure loss only after a foreclosure loss exceeds the borrower’s equity, any private mortgage insurance, and the funded first loss account. Based on the delinquency results for states where properties are located and the Company’s historical loss experience, the estimated foreclosure losses are immaterial.

The Company, from time to time, may be a defendant in legal proceedings relating to the conduct of its banking business. Most of such legal proceedings are a normal part of the banking business and, in management’s opinion as of September 30, 2025 and June 30, 2025, the financial condition and results of operations of the Company would not be materially affected by the outcome of such legal proceedings.

Note 14- Fair Value of Assets and Liabilities

The Company uses fair value measurements to record fair value adjustments to certain assets and to determine fair value disclosures. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Fair value is best determined based upon quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. These techniques are significantly affected by the assumptions used, including the discount rate and estimate of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument.

Fair value accounting guidance provides a consistent definition of fair value, which focuses on exit price in an orderly transaction (that is, not a forced liquidation or distressed sale) between market participants at the measurement date under current market conditions. If there has been a significant decrease in the volume and level of activity for the asset, a change in valuation technique or the use of multiple valuation techniques may be appropriate. In such instances, determining the price at which willing market participants would transact at the measurement date under current market conditions depends on the facts and circumstances and requires the use of significant judgment. The fair value is a reasonable point within the range that is most representative of fair value under current market conditions.

In accordance with this guidance, the Company groups its financial assets and liabilities generally measured at fair value in three levels, based on the markets in which the assets are traded and the reliability of the assumptions used to determine fair value.

Level 1 – Valuation is based on quoted prices in active markets for identical assets or liabilities that the reporting entity has the ability to access at the measurement date. Level 1 assets and liabilities generally include debt and equity securities that are traded in an active exchange market. Valuations are obtained from readily available pricing sources for market transactions involving identical assets or liabilities.

Level 2 – Valuation is based on inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. The valuation may be based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the asset or liability.

Level 3 – Valuation is based on unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. Level 3 assets and liabilities may include financial instruments whose value is determined using pricing models, discounted cash flow methodologies, or similar techniques, as well as instruments for which the determination of fair value requires significant management judgment or estimation.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement.

For those available for sale debt securities where quoted prices are unavailable, fair values are calculated based on market prices of similar securities and, therefore, are classified as Level 2 within the valuation hierarchy.

The following table represents changes in the Company’s available for sale debt securities measured at fair value on a recurring basis using unobservable inputs (Level 3). The Company had one investment security measured at fair value on a recurring basis using significant unobservable inputs (Level 3) at September 30, 2025 and June 30, 2025. The investment is valued on a quarterly basis by a third-party valuation expert. The Level 3 valuation is based on the 5/30 swap curve, floated at 1%, which is considered a significant unobservable input.

The methods and assumptions that were used to estimate the fair value of financial assets and financial liabilities that are measured at fair value on a recurring and non-recurring basis have been previously disclosed. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below:

Cash and due from banks – Due to their short -term nature, the carrying amount of cash and due from banks approximates fair value and is categorized in level 1 of the fair value hierarchy.

Federal funds sold – Due to their short-term nature, the carrying amount of federal funds sold approximates the fair value and is categorized in level 1 of the fair value hierarchy.

Interest bearing deposits in other financial institutions- Due to their short -term nature, the carrying amount of interest- bearing deposits in other financial institutions approximates fair value and is categorized in level 1 of the fair value hierarchy.

29

Table of Contents

Available for sale securities – For those available for sale debt securities where quoted prices are unavailable, fair values are calculated based on market prices of similar securities and, therefore, are classified as level 2 within the valuation hierarchy. For those available for sale debt securities where market prices of similar securities are not available because of the lack of observable market data, they are valued on a quarterly basis by a third-party valuation expert and, therefore, are classified as level 3 within the valuation hierarchy.

Held to maturity debt securities-The fair value is estimated using quoted market prices or by pricing models and is categorized as level 2 of the fair value hierarchy.

Loans– The fair value of variable rate loans that reprice frequently are based on carrying values. The fair value of other loans is estimated by discounting future cash flows using current rates at which similar loans would be made to borrowers with similar credit ratings and is categorized in level 3 of the fair value hierarchy. Loans held for sale are included with loans, net above, with fair value based on commitments on hand from investors or prevailing market prices and is categorized in level 3 of the fair value hierarchy.

Investments in restricted stock – No secondary market exists for FHLB stock. The stock is bought and sold at par by the FHLB and management believes the carrying amount approximates fair value and is categorized in level 2 of the fair value hierarchy.

Interest receivable – Due to their short -term nature, the carrying amount approximates fair value and is categorized in level 1 of the fair value hierarchy.

Deposits – Fair value of deposits with no stated maturity, such as demand deposits, savings, and money market accounts, by definition, is the amount payable on demand on the reporting date. Fair value of fixed rate time deposits is estimated using discounted cash flows applying interest rates currently offered on similar time deposits. Deposits are categorized in level 2 of the fair value hierarchy.

Federal Home Loan Bank (FHLB) advances – The carrying amount approximates fair value and is categorized in level 2 of the fair value hierarchy.

Accrued interest payable – Due to their short-term nature, the carrying amount approximates fair value and is categorized in level 1 of the fair value hierarchy.

The estimated fair value of fee income on letters of credit at September 30, 2025 and June 30, 2025 is insignificant. Loan commitments on which the committed interest rate is less than the current market rate are also insignificant at September 30, 2025 and June 30, 2025.

Note 15- Revenue Recognition

In accordance with FASB Accounting Standards Codification Topic 606, Revenue from Contracts with Customers (Topic 606) and all subsequent amendments, the Company’s services that fall within the scope of Topic 606 are presented within non-interest income and are recognized as revenue as the Company satisfies its obligation to the customer. All of the Company’s revenue from contracts with customers in the scope of Topic 606 is recognized within non-interest income which includes service charges on deposit accounts and the sale of foreclosed assets.

A description of the Company’s revenue streams accounted for under Topic 606 follows:

Service Charges on Deposit Accounts: Service charges on deposit accounts relate to fees generated from a variety of deposit products and services rendered to customers. Charges include, but are not limited to, overdraft fees, non-sufficient fund fees, dormant fees, and monthly service charges. Such fees are recognized concurrent with the event on a daily basis or on a monthly basis depending upon the customer’s cycle date.

Gains (Losses) on Sales of Foreclosed Assets: The Company records a gain or loss from a sale of foreclosed assets when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. If the Company finances the sale of foreclosed asset to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the foreclosed asset is derecognized, and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present.

Overview

Net Interest Income. Our primary source of income is net interest income. Net interest income is the difference between interest income, which is the income we earn on our loans and investments, and interest expense, which is the interest we pay on our deposits and borrowings.

Provision for (Recovery of) Credit Losses. We charge (credit) provisions for (recovery of) credit losses to operations in order to maintain our allowance for credit losses on loans and reserve for unfunded commitments at a level that is considered reasonable and necessary to absorb expected credit losses inherent in the loan portfolio and expected losses on commitments to grant loans that are expected to be advanced at the consolidated balance sheet date. In determining the level of the allowance for credit losses, we consider our past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions, and the levels of non-performing and other classified loans. The amount of the allowance is based on estimates and the ultimate losses may vary from such estimates as more information becomes available or conditions change. We assess the allowance for (recovery of) credit losses on a quarterly basis and make provisions for credit losses in order to maintain the allowance.

Non-interest Income. Our primary sources of non-interest income are mortgage banking income, service charges on deposit accounts and net gains in the cash surrender value of bank owned life insurance. Other sources of non-interest income sometimes include net gain or losses on sales and calls of securities, net gain or loss on disposal of foreclosed assets and other income.

Non-Interest Expenses. Our non-interest expenses consist of salaries and employee benefits, net occupancy and equipment, data processing and office, professional fees, marketing expenses, foreclosed assets and other general and administrative expenses, including premium payments we make to the FDIC for insurance of our deposits.

Provision for Income Taxes. Our income tax expense is the total of the current year income tax due or refundable and the change in deferred tax assets and liabilities. Deferred tax assets and liabilities are the expected future tax amounts for the temporary differences between the carrying amounts and the tax basis of assets and liabilities, computed using enacted tax rates. A valuation allowance, if needed, reduces deferred tax assets to the amounts expected to be realized.

Summary of Significant Accounting Policies and Estimates

The discussion and analysis of the financial condition and results of operations are based on our consolidated financial statements, which are prepared in conformity with U.S. GAAP. The preparation of these financial statements requires management to make estimates and assumptions affecting the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities, and the reported amounts of income and expenses. We consider the accounting policies discussed below to be significant accounting policies. The estimates and assumptions that we use are based on historical experience and various other factors and are believed to be reasonable under the circumstances. Actual results may differ from these estimates under different assumptions or conditions, resulting in a change that could have a material impact on the carrying value of our assets and liabilities and our results of operations.

In 2012, the JOBS Act was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for qualifying public companies. As an “emerging growth company” we may delay adoption of new or revised accounting pronouncements applicable to public companies until such pronouncements are made applicable to private companies. We intend to take advantage of the benefits of this extended transition period. Accordingly, our financial statements may not be comparable to companies that comply with such new or revised accounting standards.

The following represent our significant accounting policies and estimates:

Allowance for Credit Losses. We establish the allowance for credit losses through charges (credits) to earnings in the form of a provision for (recovery of) credit losses. Loan losses are charged against the allowance for credit losses for the difference between the carrying value of the loan and the estimated net realizable value or fair value of the collateral, if collateral dependent, when management believes that the collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance.

The allowance for credit losses (“ACL”) at September 30, 2025 represents the Company’s current estimate of the lifetime credit losses expected from its loan portfolio. Management estimates the ACL by projecting a lifetime loss rate conditional on a forecast of economic parameters and other qualitative adjustments, for the loans’ expected remaining term.

Management’s judgment in determining the level of the allowance is based on evaluations of historical loan losses, current conditions and reasonable and supportable forecasts relevant to the collectability of loans. In addition, management’s estimate of expected credit losses is based on the weighted-average remaining maturity of loans held for investment, and changes in expected prepayment behavior may result in changes in the remaining life of loans and expected credit losses.

The allowance may be affected materially by a variety of qualitative factors that the Company considers to reflect its current judgement of various events and risks that are not measured in our statistical procedures. These qualitative risk factors include: (1) lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices; (2) changes in the value of underlying collateral for collateral dependent loans; (3) nature and volume of the portfolio and terms of loans; (4) volume and severity of past due, classified and nonaccrual loans as well as loan modifications; (5) existence and effect of any concentrations of credit and changes in the level of such concentrations; (6) experience, ability, and depth of lending department management and other relevant staff; (7) quality of loan review and board of directors oversight; (8) the effect of other external factors such as competition, legal and regulatory requirements; and (9) changes in national and local economic conditions related to unemployment, house price index, and gross domestic product. This evaluation is inherently subjective because it requires estimates that are susceptible to significant revision as more information becomes available. In evaluating the level of the allowance, we consider a range of possible assumptions and outcomes related to the various factors identified above. The level of the allowance is particularly sensitive to changes in the actual and forecasted probability of default of benchmarked banks and changes in current conditions or reasonably expected future conditions affecting the collectability of loans.

Changes in the Wisconsin unemployment rate, the Wisconsin annual housing price index and the Wisconsin annual gross domestic product could have a material impact on the model’s estimation of the allowance for credit losses. Marathon Bank’s methodology for maintaining its allowance for credit losses includes various levels within each of the aforementioned criteria. Set forth below is a hypothetical change to the next level within Marathon Bank’s allowance calculation. Changing these levels as of September 30, 2025, from those actually used on September 30, 2025 to the next highest or lowest level resulted in an increase in Marathon Bank’s allowance for credit losses of $108,000, or 6.3%.

Although we believe that we use the best information available to establish the allowance for credit losses, future adjustments to the allowance may be necessary if economic conditions differ substantially from the assumptions used in making the evaluation. In addition, the FDIC and the WDFI, as an integral part of their examination process, periodically review our allowance for credit losses, and as a result of such reviews, we may have to adjust our allowance for credit losses. However, regulatory agencies are not directly involved in establishing the allowance for credit losses as the process is our responsibility and any increase or decrease in the allowance is the responsibility of management. A large loss could deplete the allowance and require increased provisions to replenish the allowance, which would adversely affect earnings.

Provision for Income Taxes. Deferred tax assets and liabilities are recognized for the estimated future tax consequences attributable to 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 in effect for the year 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. Deferred tax assets are reduced by a valuation allowance when, in the opinion of management, it is more likely than not that some portion or all of the deferred tax assets will not be realized.

We recognize the tax effects from an uncertain tax position in the financial statements only if the position is more likely than not to be sustained on audit, based on the technical merits of the position. We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more likely than not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the financial statements is the largest benefit that has a greater than 50% likelihood of being realized, upon ultimate settlement with the relevant tax authority. We recognize interest and penalties accrued or released related to uncertain tax positions in current income tax expense or benefit.

Allowance for Credit Losses-Available for Sale Debt Securities. For available-for-sale debt securities in an unrealized loss position, the Company first assesses whether it intends to sell, or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through a provision for credit losses. For debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit losses or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit loss is recognized in other comprehensive income.

Allowance for Credit Losses-Held-to-Maturity Debt Securities. Management measures expected credit losses on held-to-maturity debt securities on a collective basis by major security group and any other risk characteristics used to segment the portfolio. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts.

Foreclosed Assets. Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less estimated cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets.

Comparison of Financial Condition at September 30, 2025 and June 30, 2025

Total Assets. Total assets increased $7.2 million, or 3.0%, to $246.0 million at September 30, 2025 from $238.8 million at June 30, 2025. The increase was primarily due to an increase in loans, net of $5.5 million, or 2.7% and an increase in cash and cash equivalents of $1.1 million, or 7.5%. The remaining asset categories showed no significant changes when comparing September 30, 2025 with June 30, 2025 with the exception of interest earning deposits in other financial institutions which increased by $581,000, or 244.9% due to the reasons discussed in the following section under Cash and Cash Equivalents.

Cash and Cash Equivalents. Total cash and cash equivalents increased $1.1 million, or 7.5%, to $15.5 million at September 30, 2025 from $14.4 million at June 30, 2025, primarily due to an increase in deposits of $6.5 million, or 4.2% which was offset by an increase in loans of $5.5 million, or 2.7%.

Debt Securities Available for Sale. Total debt securities available for sale remained substantially the same at approximately $5.2 million when comparing September 30, 2025 with June 30, 2025.

Loans. Gross loans increased $5.5 million, or 2.7%, to $208.0 million at September 30, 2025 from $202.5 million at June 30, 2025. The increase was primarily due to an increase in multi-family real estate loans of $2.9 million, or 6.1% and an increase in one-to-four-family residential loans of $2.6 million, or 4.6%. The increase in multi-family real estate loans and one-to-four-family residential loans was due to a strategic decision to grow both of these portfolios. The remaining categories of loans showed no substantial changes.

Foreclosed Assets. Foreclosed assets, net remained unchanged at $996,000 when comparing September 30, 2025 with June 30, 2025.

Deposits. Total deposits increased by $6.5 million, or 3.7%, to $181.7 million at September 30, 2025 from $175.2 million at June 30, 2025 primarily due to an increase in demand, NOW and money market deposits of $3.9 million, or 8.1% and an increase in savings accounts of $2.8 million, or 7.4%. The remaining categories of deposits showed no significant changes. The increase in demand, NOW, money market and savings deposits was due to the Company’s increased focus on relationship management by obtaining customers’ deposit balances when granting loans to new customers. In addition, the increase in savings account balances was related to one customer’s significant deposit in preparation for a planned distribution of funds.

Federal Home Loan Bank (FHLB) Advances. FHLB advances remained the same at $15.0 million when comparing September 30, 2025 with June 30, 2025.

Table of Contents

The following table presents the effects of changing rates and volumes on our net interest income for the periods indicated. The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The total column represents the sum of the prior columns. For purposes of this table, changes attributable to both rate and volume, which cannot be segregated, have been allocated proportionately based on the changes due to rate and the changes due to volume.

Comparison of Operating Results for the Three Months Ended September 30, 2025 and 2024

General. Net income was $444,000 for the three months ended September 30, 2025, an increase of $269,000, or 154.0%, from net income of $175,000 for the three months ended September 30, 2024. The increase in net income was primarily attributable to an increase in net interest income of $533,000. This increase was offset by a decrease in the recovery of credit losses of $115,000, from a recovery of credit losses of $155,000 for the three months ended September 30, 2024 to a recovery of credit losses of $40,000 for the three months ended September 30, 2025, and a slight increase in non-interest expenses of $82,000.

Interest Income. Interest income increased by $563,000, or 24.4%, to $2.9 million for the three months ended September 30, 2025 as compared to the three months ended September 30, 2024 primarily due to an increase in loan interest income of $545,000.

Loan interest income increased by $545,000, or 26.3%, to $2.6 million for the three months ended September 30, 2025 as compared to the three months ended September 30, 2024, due to an increase in the average yield on loans and an increase in the average balance of loans. The average yield on the loan portfolio increased by 59 basis points from 4.66% for the three months ended September 30, 2024 to 5.25% for the three months ended September 30, 2025. The average balance of the loan portfolio increased by $22.2 million, or 12.3%, to $201.9 million for the three months ended September 30, 2025 from $179.7 million for the three months ended September 30, 2024. The increase in the average yield on the loan portfolio was the result of higher interest rates on new loan originations. The increase in the average balance of the loan portfolio was primarily related to new loan growth.

Debt securities interest income increased by $11,000, or 23.9%, to $57,000 for the three months ended September 30, 2025 from $46,000 for the three months ended September 30, 2024 due to an increase in the average yield on the debt securities portfolio of 145 basis points to 4.05% for the three months ended September 30, 2025 which was offset by a decrease of $1.4 million in the average balance of debt securities to $5.7 million for the three months ended September 30, 2025 from $7.1 million for the three months ended September 30, 2024. The increase in the average yield on the debt securities portfolio was due to a $1.0 million floating rate corporate bond that was called in October 2025 that had a coupon rate of 10.17% for the last three months prior to being called. It was purchased in May 2021. The average balance of debt securities continued to decrease as a result of securities calls and paydowns.

​

Interest Expense. Interest expense increased $30,000, or 3.4%, to $922,000 for the three months ended September 30, 2025 from $892,000 for the three months ended September 30, 2024, due to an increase of $19,000 in interest paid on FHLB borrowings and an increase of $11,000 in interest paid on deposits.

Interest expense on deposits increased slightly by $11,000, or 1.4%, to $782,000 for the three months ended September 30, 2025 from $771,000 for the three months ended September 30, 2024 due to an increase in the average balance of deposits offset by a slight decrease in the average rate paid on all deposit categories. The increase in the average balance of deposits was the result of the initiation of new loan relationships which increased the average balances of demand, NOW, money market and savings deposit accounts while the decrease in the average balances of certificate of deposit accounts was primarily related to us successfully migrating customer funds from fixed-rate certificate of deposit products into more liquid deposit products with variable rates. The average rate paid on deposits decreased by seven basis points to 1.96% for the three months ended September 30, 2025 from 2.03% for the three months ended September 30, 2024 due to declining interest rates and a shift in customer funds from fixed-rate certificates of deposit into more liquid deposit products with variable rates.

Interest paid on FHLB borrowings increased $19,000, from $121,000 for the three months ended September 30, 2024 to $140,000 for the three months ended September 30, 2025. The increase in interest paid on borrowings was due to the average balance of FHLB advances increasing by $3.4 million to $15.0 million for the three months ended September 30, 2025 from $11.6 million for the three months ended September 30, 2024. The average rate paid on borrowings decreased slightly from 4.19% for the three months ended September 30, 2024 to 3.75% for the three months ended September 30, 2025 due to a decrease in the federal funds rate.

Net Interest Income. Net interest income increased by $533,000, or 37.5%, to $2.0 million for the three months ended September 30, 2025 from $1.4 million for the three months ended September 30, 2024. Net interest rate spread increased by 56 basis points to 3.05% for the three months ended September 30, 2025 from 2.49% for the three months ended September 30, 2024, reflecting a 50 basis points increase in the average yield on interest-earning assets and a six basis points decrease in the average interest rate paid on interest-bearing liabilities. The net interest margin increased to 3.49% for the three months ended September 30, 2025 from 2.85% for the three months ended September 30, 2024. The increase in the average yield on interest earning assets for the three months ended September 30, 2025 compared to the three months ended September 30, 2024 was primarily due to an increase in the average yield of all interest-earning asset categories (with the exception of cash and cash equivalents which decreased by 114 basis points due to a drop in the federal funds rate) related to the increase in market interest rates over the past year and an increase in the percentage of commercial and multi-family real estate loans making up the total loan portfolio which generally carry higher interest rates than the other categories of loans. Net interest-earning assets increased by $14.3 million, or 39.3%, to $50.6 million for the three months ended September 30, 2025 from $36.3 million for the three months ended September 30, 2024.

Provision for (Recovery of) Credit Losses. We charge (credit) provisions for (recovery of) credit losses to operations in order to maintain our allowance for credit losses on loans and reserve for unfunded commitments at a level that is considered reasonable and necessary to absorb expected credit losses inherent in the loan portfolio and expected losses on commitments to grant loans that are expected to be advanced at the consolidated balance sheet date. In determining the level of the allowance for credit losses, we consider our past loan loss experience, known and inherent risks in the portfolio, adverse situations that may affect the borrower’s ability to repay, the estimated value of any underlying collateral, composition of the loan portfolio, current economic conditions, and the levels of non-performing and other classified loans. The amount of the allowance is based on estimates and the ultimate losses may vary from such estimates as more information becomes available or conditions change. We assess the allowance for credit losses on a quarterly basis and make provisions for (recovery of) credit losses in order to maintain the allowance.

Based on our evaluation of the above factors, we recorded a recovery of credit losses of $40,000 for the three months ended September 30, 2025 compared to a recovery of credit losses of $155,000 for the three months ended September 30, 2024. The decrease in recovery when comparing the two periods was primarily related to an increase in the loan portfolio for the three months ended September 30, 2025. The recovery was related to the projected future economic conditions in our market area stabilizing over the next two years, an increase in prepayments in both consumer and commercial loans, which was impactful to the weighted average life of the loan portfolio and the continuous recoveries of two legacy charge-offs. During the three months ended September 30, 2025, the Company updated the historical look-back method period used in developing lifetime loss estimate. Management believes the extended period better reflects a set of relevant loss experience. These predictions align with the Bank’s historic charge-off history over the past 9 years adjusted for current and forecasted conditions.

The allowance for credit losses was $1.7 million, or 0.80%, of loans outstanding at September 30, 2025 and $1.7 million, or 0.92%, of loans outstanding at September 30, 2024.

To the best of our knowledge, we have recorded our best estimate of expected losses in the loan portfolio and for unfunded commitments at September 30, 2025. However, future changes in the factors described above, including, but not limited to, actual loss experience with respect to our loan portfolio, could result in material increases in our provision for credit losses. In addition, the WDFI and the FDIC, as an integral part of their examination process, will periodically review our allowance for credit losses, and as a result of such reviews, we may have to adjust our allowance for credit losses. However, regulatory agencies are not directly involved in establishing the allowance for credit losses as the process is our responsibility and any increase or decrease in the allowance is the responsibility of management.

​

Non-interest expenses were $1.6 million for the three months ended September 30, 2025 and 2024. The increase was primarily related to an increase in salaries and benefits associated with the new branch we opened in Brookfield, Wisconsin in January 2024. The remaining changes in other non-interest expense categories were not significant.

​

Provision for Income Taxes. Income tax expense was $103,000 for the three months ended September 30, 2025, an increase of $62,000, as compared to income tax expense of $41,000 for the three months ended September 30, 2024. The increase in income tax expense was primarily the result of an increase in income before provision for income taxes. The effective tax rate for the three months ended September 30, 2025 and 2024 was 18.8% for both periods.

Asset Quality

​

Loans Past Due and Non-Performing Assets. Loans are reviewed on a regular basis. Non-accrual loans are loans for which collectability is questionable and, therefore, interest on such loans will no longer be recognized on an accrual basis. All loans that become 90 days or more delinquent are placed on non-accrual status unless the loan is well secured and in the process of collection. When loans are placed on non-accrual status, unpaid accrued interest is fully reversed, and further income is recognized only to the extent received on a cash basis or cost recovery method.

When we acquire real estate as a result of foreclosure, the real estate is classified as real estate owned. Assets acquired through, or in lieu of, loan foreclosure are held for sale and are initially recorded at fair value less estimated cost to sell at the date of foreclosure, establishing a new cost basis. Subsequent to foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value less cost to sell. Revenue and expenses from operations and changes in the valuation allowance are included in net expenses from foreclosed assets. Costs relating to the development and improvement of the property, however, are capitalized to the extent of estimated fair value less estimated costs to sell.

Non-performing assets include other real estate owned of $996,000 at September 30, 2025 and June 30, 2025. During the year ended June 30, 2023, the Company foreclosed on collateral supporting a construction loan which was valued at $2.3 million and was included in foreclosed assets (OREO), net. The valuation was based on independent appraisals subject to certain discounts less estimated costs to sell. A subsequent independent appraisal was obtained in April 2024 subject to certain discounts less estimated costs to sell. After adjusting for estimated costs to sell, the revised valuation was $1.4 million resulting in a provision for valuation allowance of $937,100 being recorded during the year ended June 30, 2024. An offer to sell the property for $1.1 million was accepted by the Company in August 2025 resulting in a provision for valuation allowance of $378,767 being recorded during the year ended June 30, 2025. The sale is subject to customary due diligence and has not closed as of November 12, 2025. Non-performing loans at September 30, 2025 consisted of two one-to four-family residential loans that were fully secured compared to one one-to four-family residential loan that was fully secured at June 30, 2025.

Classified Assets. Federal regulations provide for the classification of loans and other assets, such as debt and equity securities considered to be of lesser quality, as “substandard,” “doubtful” or “loss.” An asset is considered “substandard” if it is inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. “Substandard” assets include those characterized by the “distinct possibility” that the insured institution will sustain “some loss” if the deficiencies are not corrected. Assets classified as “doubtful” have all of the weaknesses inherent in those classified “substandard,” with the added characteristic that the weaknesses present make “collection or liquidation in full,” on the basis of currently existing facts, conditions, and values, “highly questionable and improbable.” Assets classified as “loss” are those considered “uncollectible” and of such little value that their continuance as assets without the establishment of an allowance for credit loss is not warranted. Assets which do not currently expose the insured institution to sufficient risk to warrant classification in one of the aforementioned categories but possess weaknesses are designated as “special mention” or “watch” by our management.

Set forth below is a schedule of classified loans as of September 30, 2025 and June 30, 2025.

Allowance for Credit Losses

Allowance for Credit Losses. We establish the allowance for credit losses through charges (credits) to earnings in the form of a provision for (recovery of) credit losses. Credit losses are charged against the allowance for credit losses for the difference between the carrying value of the loan and the estimated net realizable value or fair value of the collateral, if collateral dependent, when management believes that the collectability of the principal is unlikely. Subsequent recoveries, if any, are credited to the allowance.

The allowance for credit losses (“ACL”) at September 30, 2025 represents the Company’s current estimate of the lifetime credit losses expected from its loan portfolio. Management estimates the ACL by projecting a lifetime loss rate conditional on a forecast of economic parameters and other qualitative adjustments, for the loans’ expected remaining term.

45

Table of Contents

Management’s judgment in determining the level of the allowance is based on evaluations of historical loan losses, current conditions and reasonable and supportable forecasts relevant to the collectability of loans. In addition, management’s estimate of expected credit losses is based on the weighted-average remaining maturity of loans held for investment, and changes in expected prepayment behavior may result in changes in the remaining life of loans and expected credit losses.

The allowance may be affected materially by a variety of qualitative factors that the Company considers to reflect its current judgement of various events and risks that are not measured in our statistical procedures. These qualitative risk factors include: (1) lending policies and procedures, including underwriting standards and collection, charge-off, and recovery practices; (2) changes in the value of underlying collateral for collateral dependent loans; (3) nature and volume of the portfolio and terms of loans; (4) volume and severity of past due, classified and nonaccrual loans as well as loan modifications; (5) existence and effect of any concentrations of credit and changes in the level of such concentrations; (6) experience, ability, and depth of lending department management and other relevant staff; (7) quality of loan review and board of directors oversight; (8) the effect of other external factors such as competition, legal and regulatory requirements; and (9) changes in national and local economic conditions related to unemployment, house price index, and gross domestic product. This evaluation is inherently subjective because it requires estimates that are susceptible to significant revision as more information becomes available. In evaluating the level of the allowance, we consider a range of possible assumptions and outcomes related to the various factors identified above. The level of the allowance is particularly sensitive to changes in the actual and forecasted probability of default of benchmarked banks and changes in current conditions or reasonably expected future conditions affecting the collectability of loans.

Although we believe that we use the best information available to establish the allowance for credit losses, future adjustments to the allowance may be necessary if economic conditions differ substantially from the assumptions used in making the evaluation. In addition, the FDIC and the WDFI, as an integral part of their examination process, periodically review our allowance for credit losses, and as a result of such reviews, we may have to adjust our allowance for credit losses. However, regulatory agencies are not directly involved in establishing the allowance for credit losses as the process is our responsibility and any increase or decrease in the allowance is the responsibility of management. A large loss could deplete the allowance and require increased provisions to replenish the allowance, which would adversely affect earnings.

Liquidity and Capital Resources

Liquidity describes our ability to meet the financial obligations that arise in the ordinary course of business. Liquidity is primarily needed to meet the borrowing and deposit withdrawal requirements of our customers and to fund current and planned expenditures. Our primary sources of funds are deposits, principal and interest payments on loans and securities, proceeds from the sale of loans, and proceeds from maturities of securities. We also have the ability to borrow from the Federal Home Loan Bank of Chicago. At September 30, 2025, we had a $83.4 million line of credit with the Federal Home Loan Bank of Chicago, which had $15.0 million in borrowings outstanding as of that date. The Bank also has $17.0 million available to borrow from the Federal Reserve Bank which is pledged by multi-family loans and an unsecured Federal Funds purchasing limit of $5.0 million with the Bank’s correspondent bank. There were no borrowings under these arrangements at September 30, 2025.

While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows and loan prepayments are greatly influenced by general interest rates, economic conditions, and competition. Our most liquid assets are cash and short-term investments including interest-bearing demand deposits. The levels of these assets are dependent on our operating, financing, lending, and investing activities during any given period.

Our cash flows are comprised of three primary classifications: cash flows from operating activities, investing activities, and financing activities. Net cash provided by operating activities was $464,000 and $945,000 of cash provided by operating activities for the three months ended September 30, 2025 and 2024, respectively. Net cash provided by (used in) investing activities, which consists primarily of disbursements for loan origination, the purchase of securities, and the purchase of premises and equipment offset by principal collections on loans, proceeds from the sale of securities and proceeds from maturing securities and pay downs on securities, was $5.9 million used in investing activities compared to $7.5 million provided by investing activities for the three months ended September 30, 2025 and 2024, respectively. Net cash provided by (used in) financing activities, consisting of activity in deposit accounts and borrowings, was $6.5 million provided by financing activities compared to $3.9 million being used in financing activities for the three months ended September 30, 2025 and 2024, respectively.

We are committed to maintaining a strong liquidity position. We monitor our liquidity position on a daily basis. We anticipate that we will have sufficient funds to meet our current funding commitments. Based on our deposit retention experience, current pricing strategy and regulatory restrictions, we anticipate that a substantial portion of maturing time deposits will be retained, and that we can supplement our funding with borrowings in the event that we allow these deposits to run off at maturity.

At September 30, 2025, Marathon Bank was classified as “well capitalized” for regulatory capital purposes. See Note 10-Minimum Regulatory Capital Requirements in the accompanying consolidated financial statements for additional information.

Off-Balance Sheet Arrangements and Aggregate Contractual Obligations

Commitments. As a financial services provider, we routinely are a party to various financial instruments with off-balance-sheet risks, such as commitments to extend credit and unused lines of credit. While these contractual obligations represent our future cash requirements, a significant portion of commitments to extend credit may expire without being drawn upon. Such commitments are subject to the same credit policies and approval process accorded to loans we make. At September 30, 2025, we had outstanding commitments to originate loans of $7.5 million, and no outstanding commitments to sell loans. We anticipate that we will have sufficient funds available to meet our current lending commitments. Time deposits that are scheduled to mature in one year or less from September 30, 2025 totaled $45.1 million, which include $2.3 million in brokered certificates of deposit. Management expects that a substantial portion of the maturing time deposits will be renewed. However, if a substantial portion of these deposits is not retained, we may utilize additional Federal Home Loan Bank advances or other borrowings, which may result in higher levels of interest expense.

Contractual Obligations. In the ordinary course of our operations, we enter into certain contractual obligations. Such obligations include data processing services, operating leases for premises and equipment, agreements with respect to borrowed funds and deposit liabilities.

Recent Accounting Pronouncements

Please refer to Note 1 to the consolidated financial statements for a description of recent accounting pronouncements that may affect our financial condition and results of operations.

Impact of Inflation and Changing Price

The financial statements and related data presented herein have been prepared in accordance with U.S. GAAP, which requires the measurement of financial position and operating results in terms of historical dollars without considering changes in the relative purchasing power of money over time due to inflation. The primary impact of inflation on our operations is reflected in increased operating costs. Unlike most industrial companies, virtually all of the assets and liabilities of a financial institution are monetary in nature. As a result, interest rates, generally, have a more significant impact on a financial institution’s performance than does inflation. Interest rates do not necessarily move in the same direction or to the same extent as the prices of goods and services.

Item 3. Quantitative and Qualitative Disclosure about Market Risk

A smaller reporting company is not required to provide the information related to this item.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are the controls and other procedures that are designed to ensure that information required to be disclosed in the reports that the Company files or submits under the Securities and Exchange Act of 1934, as amended (the “Exchange Act”) is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is accumulated and communicated to management, including the Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can only provide reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must necessarily reflect the fact that there are resource constraints and that management is required to apply its judgement in evaluating the benefits of possible controls and procedures relative to their costs.

Under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer , the Company has evaluated the effectiveness of the Company’s disclosure controls and procedures as defined in Rules 13a-15 and 15d-15(e) under the Exchange Act as of September 30, 2025. Based upon that evaluation, the Chief Executive Officer and Chief Financial Officer concluded that, as of September 30, 2025, the Company’s disclosure controls and procedures are effective to ensure that information required to be disclosed in the reports that the Company files or submits under the Exchange Act is recorded, processed, summarized and reported, within the time periods specified in the Securities and Exchange Commission’s rules and forms.

Internal Control over Financial Reporting
