AND SUBSIDIARY Notes to Unaudited Consolidated Financial Statements Note 1: Summary of Significant Accounting Policies Organization EWSB Bancorp, Inc. (the “Company”), a Maryland corporation and registered bank holding company, was formed to serve as the holding company for East Wisconsin Savings Bank (the “Bank”), upon conversion of Wisconsin Mutual Bancorp, MHC to the stock form of organization, which was completed on September 20, 2024. In connection with the conversion, the Company sold 752,538 shares of common stock, par value $ 0.01 , including 52,678 shares sold to the Bank’s Employee Stock Ownership Plan, at $ 10.00 per share in its subscription offering for gross proceeds (before deducting offering expenses) of approximately $ 7.5 million. Shares of the Company’s common stock began trading on September 24, 2024 on the OTCQB Market under the trading symbol “EWSB”. The Bank provides a variety of financial services to individual and corporate customers. The Bank operates as a full-service financial institution with a primary market area including, but not limited to, east central Wisconsin. The Company is subject to the regulations of certain federal and state agencies and undergoes periodic examinations by those regulatory authorities. Principles of Consolidation The financial statements include the accounts of EWSB Bancorp, Inc. and its subsidiary, East Wisconsin Savings Bank. All significant intercompany balances and transactions have been eliminated. Basis of Presentation The accompanying unaudited Consolidated Financial Statements were prepared in accordance with GAAP and the instructions to Form 10-Q and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by GAAP for complete financial statements and should be read in conjunction with the audited financial statements and related notes of EWSB Bancorp, Inc’s Consolidated Financial Statements and footnotes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. The Company has not changed its significant accounting and reporting policies from those disclosed in the audited financial statements for the year ended December 31, 2024. Use of Estimates in Preparation of Financial Statements The preparation of the accompanying financial statements in conformity with accounting principles generally accepted in the United States of America (“GAAP”) requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenue and expenses during the reporting period. The determination of the allowance for credit losses and valuation allowance on deferred tax assets are particularly subject to change in the near term. Actual results may differ from these estimates. The results of operations for the three months ended March 31, 2025, are not necessarily indicative of results that may be expected for any other interim period or the entire fiscal year ending December 31, 2025. 7 Table of Contents EWSB BANCORP, INC.

Based on our analysis of these securities, the decline in value was unrelated to credit loss and is related to changes in market interest rates since purchase, and therefore, changes in value for securities were included in other comprehensive income. In analyzing whether unrealized losses on debt securities are not related to credit losses, management takes into consideration, as applicable, whether the securities are issued by a governmental body or agency, whether the rating agency has downgraded the securities, industry analysts’ reports, the financial condition and performance of the issuer, and the quality of any underlying assets or credit enhancements. Market valuations and credit loss analysis on assets in the AFS securities portfolio are reviewed and monitored on a quarterly basis. None of the investments in our AFS securities portfolio were past due as of March 31, 2025. Management has the ability and intent to hold the securities for the foreseeable future and no declines are deemed to be related to credit losses; therefore, no provision for expected credit losses or allowance is carried for the AFS portfolio. The following is a summary of amortized cost and estimated fair value of debt securities by contractual maturity as of March 31, 2025.

This methodology consists of measuring the value of investments on a collective basis when similar risk characteristics exist. Our investment policy requires securities designated as HTM to carry an explicit or implicit guarantee of the United States Government (i.e., issued by the U.S. Treasury and federal agencies of the United States). Market valuations and credit loss analysis on assets in the HTM securities portfolio are reviewed and monitored on a quarterly basis. None of the investments in our HTM securities portfolio were past due as of March 31, 2025. An allowance for credit losses (“ACL”) is not calculated or recorded based on the implied guarantee of these securities. The following table summarizes the remaining contractual principal maturities of investment securities classified as HTM as of March 31, 2025. For United States agency debentures, the expected maturity is the actual contractual maturity of the notes. Expected remaining maturities for certain United States agency debentures may occur earlier than their contractual maturities because the note issuers have the right to call outstanding amounts ahead of their contractual maturity. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ March 31, 2025 ​ ​ Amortized ​ Estimated Held-to-maturity ​ Cost ​ Fair Value Due in one year or less $ 6,341,418 $ 6,342,455 Due after one year through five years ​ 14,949,630 ​ 14,939,301 Due after five years through ten years ​ 14,414,863 ​ 14,281,719 Due after ten years ​ 3,596,905 ​ 3,535,494 Total ​ $ 39,302,816 ​ $ 39,098,969 ​ ​ ​ 10 Table of Contents EWSB BANCORP, INC.

A provision for credit loss on unfunded loan commitments of $ 46,457 was made for the three months ended March 31, 2025. No provision for credit loss on unfunded loan commitments was made for the three months ended March 31, 2024. ​ As of March 31, 2025 there were two collateral dependent loans totaling $ 11,250 in the other consumer loans segment. These loans were secured by automobiles and did not have a specific allocation to the ACL as of March 31, 2025. As of December 31, 2024 there were two collateral dependent loans totaling $ 12,704 in the other consumer loans segment. These loans were secured by automobiles and did not have a specific allocation to the ACL as of December 31, 2024. The Company regularly evaluates various attributes of loans to determine the appropriateness of the allowance for credit losses. The credit quality indicators monitored differ depending on the class of loan. Multi-family, commercial real estate, and commercial installment loans are generally evaluated using the following internally prepared ratings: ● Pass ratings are assigned to loans with adequate collateral and debt service ability such that collectability of the contractual loan payments is highly probable. ● Special mention ratings are assigned to loans where management has some concern that the collateral or debt service ability may not be adequate, though the collectability of the contractual loan payments is still probable. ● Substandard ratings are assigned to loans that do not have adequate collateral and/or debt service ability such that collectability of the contractual loan payments is no longer probable. ● Doubtful ratings are assigned to loans that do not have adequate collateral and/or debt service ability, and collectability of the contractual loan payments is unlikely. One to four family residential, home equity, equity line of credit, construction, marine and recreational, and other consumer loans are generally evaluated based on whether the loan is performing according to the contractual terms of the loan. ​ 12 Table of Contents EWSB BANCORP, INC.

Note 6: Equity and Regulatory Matters The Bank is subject to various regulatory capital requirements administered by 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 financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of assets, liabilities, and certain off balance-sheet items as calculated under regulatory accounting practices. The capital amounts and classification are also subject to qualitative judgments by the regulators about components, risk weightings, and other factors. 17 Table of Contents EWSB BANCORP, INC. AND SUBSIDIARY Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum regulatory capital amounts and ratios (set forth in the table on the next page). It is management’s opinion, as of March 31, 2025, that the Bank meets all applicable statutory capital adequacy requirements. As of March 31, 2025, the Bank is categorized as well capitalized under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum regulatory capital ratios as set forth in the table. There are no conditions or events since that notification that management believes have changed the Bank’s category. The payment of dividends by the Bank would be restricted if the Bank does not meet the minimum Capital Conservation Buffer as defined by Basel III regulatory capital guidelines and/or if, after payment of the dividend, the Bank would be unable to maintain satisfactory regulatory capital ratios. The Bank’s actual capital amounts and ratios as of March 31, 2025 and December 31, 2024, are presented in the following tables: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To Be Well Capitalized ​ ​ ​ ​ ​ ​ ​ ​ For Capital Adequacy ​ Under Prompt Corrective ​ ​ ​ Actual ​ Purposes ​ Action Provisions ​ (Dollars in Thousands) Amount Ratio Amount Ratio Amount Ratio ​ March 31, 2025 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Bank ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier 1 capital (to risk-weighted assets) ​ $ 18,044 ​ 11.0 % ≥ $ 7,358 ​ ≥ 4.5 % ≥ $ 10,628 ​ ≥ 6.5 % Tier 1 capital (to risk-weighted assets) ​ ​ 18,044 ​ 11.0 % ≥ 9,810 ​ ≥ 6.0 % ≥ 13,080 ​ ≥ 8.0 % Total capital (to risk-weighted assets) ​ ​ 19,362 ​ 11.8 % ≥ 13,080 ​ ≥ 8.0 % ≥ 16,350 ​ ≥ 10.0 % Tier 1 capital (to average assets) ​ ​ 18,044 ​ 6.6 % ≥ 10,995 ​ ≥ 4.0 % ≥ 13,744 ​ ≥ 5.0 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To Be Well Capitalized ​ ​ ​ ​ ​ ​ ​ ​ For Capital Adequacy ​ Under Prompt Corrective ​ ​ ​ Actual ​ Purposes ​ Action Provisions ​ (Dollars in Thousands) Amount Ratio Amount Ratio Amount Ratio ​ December 31, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Bank ​ ​ ​ ​ ​ ​ Common Equity Tier 1 capital (to risk-weighted assets) ​ $ 18,520 ​ 11.8 % ≥ $ 7,091 ​ ≥ 4.5 % ≥ $ 10,243 ​ ≥ 6.5 % Tier 1 capital (to risk-weighted assets) ​ 18,520 ​ 11.8 % ≥ 9,455 ​ ≥ 6.0 % ≥ 12,606 ​ ≥ 8.0 % Total capital (to risk-weighted assets) ​ 19,728 ​ 12.5 % ≥ 12,606 ​ ≥ 8.0 % ≥ 15,758 ​ ≥ 10.0 % Tier 1 capital (to average assets) ​ 18,520 ​ 6.9 % ≥ 10,709 ​ ≥ 4.0 % ≥ 13,387 ​ ≥ 5.0 % ​ In addition to the above minimum regulatory capital measures, the Board of Directors has designated that the Bank will have and maintain its tier one capital as a percentage of average total assets at a minimum of 8.0 % and its level of total capital to risk-weighted assets at a minimum of 11.0 % .

In addition to the above minimum regulatory capital measures, the State of Wisconsin requires a state-chartered savings bank to maintain a net worth ratio in an amount not less than 6.0 %. At March 31, 2025, the Bank’s net worth ratio of 5.64 % was not in compliance with the minimum requirement. 18 Table of Contents EWSB BANCORP, INC. AND SUBSIDIARY Note 7: Fair Value Measurements Accounting standards describe three levels of inputs that may be used to measure fair value (the fair value hierarchy). The level of an asset or liability within the fair value hierarchy is based on the lowest level of input significant to the fair value measurement of that asset or liability. Following is a brief description of each level of the fair value hierarchy: Level 1 - Fair value measurement is based on quoted prices for identical assets or liabilities in active observable markets. Level 2 - Fair value measurement is based on: (1) quoted prices for similar assets or liabilities in active markets; (2) quoted prices for identical or similar assets or liabilities in markets that are not active; or (3) valuation models and methodologies for which all significant assumptions are or can be corroborated by observable market data. Level 3 - Fair value measurement is based on valuation models and methodologies that incorporate at least one significant assumption that cannot be corroborated by observable market data. Level 3 measurements reflect the Company’s estimates about assumptions market participants would use if measured at fair value on a recurring basis under GAAP. Some assets and liabilities, such as securities available for sale, are measured at fair value on a recurring basis under GAAP. Other assets and liabilities, such as individually evaluated loans, may be measured at fair value on a nonrecurring basis. As of March 31, 2025 and December 31, 2024, the Company did not have any significant assets or liabilities that were measured at fair value on a nonrecurring basis. Following is a description of the valuation methodology and significant inputs used for each asset measured at fair value on a recurring basis, as well as the classification of the asset within the fair value hierarchy. Securities available for sale - Securities available for sale are classified as Level 2 measurements within the fair value hierarchy. Level 2 securities include U.S. government sponsored agencies, obligations of states and political subdivisions, corporate securities, and mortgaged-backed securities. The fair value measurement of a Level 2 security is based on recent sales of similar securities and other observable market data. ​ 19 Table of Contents EWSB BANCORP, INC.

The following disclosures include financial instruments that are not carried at fair value on the Consolidated Balance Sheets. The calculation of estimated fair values is based on market conditions at a specific point in time and may not reflect current or future fair values. Certain financial instruments generally expose the Company to limited credit risk and have no stated maturities or have short-term maturities and carry interest rates that approximate market. The carrying value of these financial instruments assumes to approximate the fair value of these instruments. These instruments include cash and cash equivalents, non-interest-bearing deposit accounts, time deposits with other financial institutions, FHLB stock, escrow deposits, FHLB advances and accrued interest receivable and payable. The fair market values of loans and interest-bearing deposits are calculated using the discounted cash flow (present value) method. ​ 20 Table of Contents EWSB BANCORP, INC.

Diluted EPS reflects the potential dilution that could occur if securities or other contracts to issue common shares (such as stock options) were exercised or converted into additional common shares that should then share in the earnings of the Company. Diluted EPS is computed by dividing net income attributed to common stockholders by the weighted-average number of common shares outstanding for the period, plus the effect of potential dilutive common share equivalents. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended March 31, 2025 Net income (loss) applicable to common shares outstanding $ ( 568,641 ) ​ ​ ​ ​ Average number of common shares outstanding 752,538 Less: Average unallocated ESOP shares ​ ​ 49,715 Average number of common shares outstanding used to calculate basic earnings per share ​ ​ 702,823 Earnings per common share basic and diluted ​ $ ( 0.81 ) ​ There were no securities or other contracts that had a dilutive effect during the three months ended March 31, 2025, and therefore the weighted-average common shares outstanding used to calculate both basic and diluted EPS are the same. 21 Table of Contents EWSB BANCORP, INC. AND SUBSIDIARY Shares held by the Employee Stock Ownership Plan (“ESOP”) that have not been allocated to employees in accordance with the terms of the ESOP, referred to as “unallocated ESOP shares”, are not deemed outstanding for EPS calculations. All unallocated ESOP shares have been excluded from the calculation of basic and diluted EPS. Earnings per share for the three months ended March 31, 2025, was calculated using 702,823 weighted average shares outstanding. EPS data is not applicable for the three months ended March 31, 2024, as the Company had no shares outstanding. Note 10: ESOP Employees of the Bank may participate in the Bank’s Employee Stock Ownership Plan (“ESOP”). The ESOP borrowed funds from the Company to purchase 52,678 shares of stock at $ 10 per share. The Bank makes discretionary contributions to the ESOP and the ESOP uses funds it receives to repay the loan. When payments are made, ESOP shares are allocated to participants based on relative compensation. The cost of shares issued to the ESOP, but not yet allocated to participants, is shown as a reduction of stockholders’ equity. Each December, the Bank makes discretionary contributions to the ESOP, which are equal to principal and interest payments required on the term loan. Expense recorded during the three months ended March 31, 2025 is $ 7,047 .

Critical Accounting Policies and Use of Critical Accounting Estimates Our accounting policies are integral to understanding the results reported. We consider accounting policies that require management to exercise significant judgment or discretion or to make significant assumptions that have, or could have, a material impact on the carrying value of certain assets or on income to be critical accounting policies. As of March 31, 2025, there have been no material changes to our critical accounting policies as compared to the critical accounting policies disclosed under “Management’s Discussion and Analysis of Financial Condition and Results of 24 Table of Contents Operations-Critical Accounting Policies” in EWSB Bancorp, Inc.’s Annual Report on Form 10-K for the year ended December 31, 2024. Comparison of Financial Condition at March 31, 2025 and December 31, 2024 Total Assets. Total assets increased $4.1 million, or 1.5%, to $277.4 million at March 31, 2025 from $273.3 million at December 31, 2024. The change was primarily the result of a $3.6 million increase in portfolio loans and a $520,000 increase in total investment securities. Cash and Cash Equivalents and Time Deposits with Other Financial Institutions. Total cash and due from banks and time deposits with other financial institutions decreased $63,000, or 1.1% to $5.6 million at March 31, 2025 from $5.7 million at December 31, 2024. The change was related to general business activity. Securities Available-for-Sale. Securities available-for-sale increased $223,000, or 1.0%, to $23.0 million at March 31, 2025 from $22.8 million at December 31, 2024. The increase was primarily due to a $515,000 increase in the market value of the portfolio due to a decrease in market interest rates during the three months ended March 31, 2025 offset by principal paydowns of $284,000 on mortgage-backed securities. The proceeds from principal paydowns are utilized to manage liquidity and support loan growth. Securities Held-to-Maturity. Securities held-to-maturity increased $296,000, or 0.8%, to $39.3 million at March 31, 2025 from $39.0 million at December 31, 2024. The increase in securities held-to-maturity was due to $296,000 in amortization of unrealized losses and discounts. Loans, net. Loans, net increased $3.6 million, or 1.9%, to $190.0 million at March 31, 2025 from $186.4 million at December 31, 2024. Construction, one- to four-family, commercial, multi-family, and home equity loans and lines of credit increased $2.4 million, $1.5 million, $133,000, $121,000, and $68,000, respectively, to $9.1 million, $131.6 million, $3.6 million, $1.4 million, and $8.1 million at March 31, 2025, respectively, as a result of loan production exceeding payoffs and amortization. These increases were partially offset by decreases to marine and recreational, commercial real estate, and other consumer loans of $265,000, $243,000, and $118,000 respectively, to $30.9 million, $2.3 million, and $4.1 million at March 31, 2025, respectively. Deposits. Total deposits increased $127,000 or 0.1% to $231.6 million at March 31, 2025, from $231.5 million at December 31, 2024. Non-interest bearing deposits decreased $1.2 million, or 12.4%, to $8.3 million at March 31, 2025, from $9.5 million at December 31, 2024. Total interest-bearing deposits, other than time deposits, decreased approximately $541,000 million, or 0.5%, to $111.2 million at March 31, 2025, from $111.8 million at December 31, 2024. Certificates of deposits increased $1.8 million, or 1.7%, to $112.1 million at March 31, 2025, from $110.3 million at December 31, 2024. The deposit mix changes were consistent with industry trends as consumers continue to transition to higher yielding term deposits due to the interest rate environment. Borrowings. We had $27.8 million of borrowings at March 31, 2025 as compared to $24.2 million at December 31, 2024. The increase of $3.6 million in FHLB borrowings were used to fund portfolio loans during the three months ended March 31, 2025. Stockholders’ Equity. Total stockholders’ equity remained consistent at $15.6 million at March 31, 2025 from and December 31, 2024. Accumulated other comprehensive loss decreased $561,000 due to an increase in the market value of the investment portfolio related to a decline in market interest rates which was offset by a decrease in retained earnings of $569,000 which resulted from the net loss incurred for the three months ended March 31, 2025. ​ 25 Table of Contents Comparison of Operating Results for the Three Months Ended March 31, 2025 and 2024 Net Income/(Loss). We recorded a net loss of $569,000 for the three months ended March 31, 2025, compared to a net loss of $377,000 for the three months ended March 31, 2024, a change of $191,000 year-over-year. The increase in our net loss year-over-year resulted primarily from a $148,000 decrease in noninterest income and an increase of $136,000 in noninterest expense offset by a $28,000 increase in net interest income and a $65,000 increase in the income tax benefit. Interest Income. Interest income increased $302,000, or 13.1%, to $2.6 million for the three months ended March 31, 2025, from $2.3 million for the three months ended March 31, 2024, due to a $306,000 increase in interest and fees on loans. The increase in interest and fees on loans was primarily due to an increase of 37 basis points in the weighted average yield on the loan portfolio to 4.92% for the three months ended March 31, 2025, from 4.55% for the same period in 2024. Interest income on securities and other investments decreased $4,000 to $316,000 for the three months ended March 31, 2025 primarily due to a $2.0 million decrease in average balance of investment securities year-over-year. The average balance decrease was primarily related to security maturities. Interest Expense. Total interest expense increased $164,000, or 11.1%, to $1.6 million for the three months ended March 31, 2025, from $1.5 million for the three months ended March 31, 2024. Interest expense on deposits increased $164,000, or 13.5%, to $1.4 million for the three months ended March 31, 2025 from $1.2 million for the three months ended March 31, 2024. This increase was due primarily to an increase in the weighted average rate paid on certificates of deposit of 16 basis points to 4.35% for the three months ended March 31, 2025 from 4.19% for the three months ended March 31, 2024, combined with an increase in the average balance of such deposits of $4.5 million year-over-year and a $3.4 million decrease in the average balance of lower-cost money market accounts year-over-year. Interest expense on borrowed funds remained consistent at $262,000 for the three months ended March 31, 2025 and 2024. The rate paid on borrowed funds declined 41 basis points to 4.12% for the three months ended March 31, 2025, from 4.53% for the three months ended March 31, 2024 while the average balance of borrowed funds increased $2.4 million, or 10.4%, to $25.8 million for the three months ended March 31, 2025 from $23.4 million for the three months ended March 31, 2024. The increase in the average balance was generally related to the measured use of borrowings to support the increase in the loan portfolio. Net Interest Income. Net interest income increased $139,000, or 16.9%, to $963,000 for the three months ended March 31, 2025 from $824,000 for the three months ended March 31, 2024, primarily due to an increase in the interest rate spread to 1.46% for the three months ended March 31, 2025 from 1.33% for the three months ended March 31, 2024 and an increase in the net interest margin to 1.51% for the three months ended March 31, 2025, from 1.35% for the three months ended March 31, 2024. The increases in the interest rate spread and the net interest margin were primarily due to an increase in the weighted average yield on loans partially offset by rates paid on interest-bearing deposits. Provision for Credit Losses. Based on management’s analysis of the adequacy of the ACL and unfunded loan commitments, a provision of $64,000 was made to the ACL and $46,000 to the ACL for unfunded loan commitments for the three months ended March 31, 2025. No provisions were made to the ACL or the ACL for unfunded loan commitments for the three months ended March 31, 2024. The adequacy of the ACL and provision expense is based on an analysis of current credit characteristics in conjunction with loss history of the loan portfolio and peer group loss data. 26 Table of Contents Noninterest Income. Noninterest income declined $148,000, or 31.7%, to $320,000 for the three months ended March 31, 2025 from $469,000 for the three months ended March 31, 2024. The change resulted primarily from a non-recurring $86,000 gain on an interest rate swap recognized in 2024 with no such gain recognized in the 2025 period, a $56,000 decline in other noninterest income related to reduced activity in investment management services and insurance agency business lines and reciprocal deposit fee income, and a $17,000 decline in mortgage banking activity. These declines in non-interest income were offset by an increase of $8,000 in bank owned life insurance income and a $4,000 increase in service charges on deposit accounts. The table below sets forth our noninterest income for the quarter ended March 31, 2025 and 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ ​ ​ ​ ​ March 31, ​ Change ​ 2025 2024 Amount Percent Service charges on deposit accounts ​ $ 14,582 ​ $ 10,380 ​ $ 4,202 40.5 % Interchange income ​ 56,354 ​ 57,139 ​ (785) (1.4) % Mortgage banking income ​ 51,606 ​ 63,845 ​ (12,239) (19.2) % Gain on sale of mortgage loans ​ ​ 45,561 ​ ​ 50,721 ​ ​ (5,160) (10.2) ​ Increase in cash value of life insurance ​ 62,225 ​ 54,201 ​ 8,024 14.8 % Gain on interest rate swap ​ ​ — ​ 86,290 ​ (86,290) (100.0) % Other ​ 90,014 ​ 146,183 ​ (56,169) (38.4) % Total noninterest income ​ $ 320,342 ​ $ 468,759 ​ $ (148,417) (31.7) % ​ Noninterest Expense. Noninterest expense increased $136,000, or 7.4%, to $2.0 million for the three months ended March 31, 2025 from $1.8 million for the three months ended March 31, 2024. Professional services fees increased $100,000 related to audit, accounting, legal and other professional services. Salary and benefit expenses increased $75,000 due to additional salary expense and benefits including expenses related to the ESOP. These increases were offset by decreases of $22,000 in FDIC insurance premiums, $14,000 in advertising, and $5,000 in net occupancy expenses.

Our benefit for income taxes increased $65,000 to a benefit of $227,000 for the three months ended March 31, 2025, from a benefit of $162,000 for the three months ended March 31, 2024 due to an increase in loss before income taxes. During 2025 , management continues to assess the available positive and negative evidence to estimate whether sufficient future taxable income will be generated to permit use of the existing deferred tax assets. A significant piece of objective negative evidence evaluated is the cumulative taxable loss incurred over the three-year period ended March 31, 2025. Such objective evidence limits the ability to fully consider other subjective evidence, such as our projections for future growth and taxable income and requires management to also consider available tax planning strategies. The Company does not have a valuation allowance as of December 31, 2024, and no valuation allowance was considered necessary as of March 31, 2025. The amount of the deferred tax asset considered realizable, however, could be adjusted, and a valuation allowance recorded, if estimates of future taxable income during the carryforward period are reduced or if further objective negative evidence in the form of cumulative loss is present and additional weight cannot be given to subjective evidence such as our projections for growth. 27 Table of Contents ​ ​ Average Balances and Yields . The following tables set forth average balance sheets, average yields and costs, and certain other information at the dates and for the periods indicated. No tax-equivalent yield adjustments have been made, as the effects would be immaterial. Average yields include the effect of net deferred fee income, discounts and premiums that are amortized or accreted to interest income or interest expense. Average balances are calculated using daily average balances. Non-accrual loans are included in the computation of average balances only.

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.

Our most significant form of market risk is interest rate risk because, as a financial institution, the majority of our assets and liabilities are sensitive to changes in interest rates. Therefore, a principal part of our operations is to manage interest rate risk and limit the exposure of our financial condition and results of operations to changes in market interest rates. Our Asset Liability Committee is responsible for evaluating the interest rate risk inherent in our assets and liabilities, for determining the level of risk that is appropriate, given our business strategy, operating environment, capital, liquidity and performance objectives, and for managing this risk consistent with the policy and guidelines approved by our board of directors. The Asset Liability Committee, which is a management-level committee, meets at least quarterly, or more frequently when necessary, is comprised of our President/Chief Executive Officer, Vice President of Lending and Vice President of Member Relations, and reports to the full board of directors on at least a quarterly basis . The Asset Liability Committee is responsible for recommending to the board of directors policies and procedures regarding asset/liability management, while it is the responsibility of the board of directors to determine whether to adopt such policies and procedures. We currently utilize a third-party modeling program, prepared on a quarterly basis, to evaluate our sensitivity to changing interest rates, given our business strategy, operating environment, capital, liquidity and performance objectives, and for managing this risk consistent with the guidelines approved by the board of directors. 29 Table of Contents Management of interest rate risk is one of the Bank’s highest priorities. In 2023, the Bank adopted a new asset/liability management policy and revamped its interest rate risk management processes and procedures to reduce interest rate risk exposure. Since then, the Bank has refined the input assumptions and various other input and output metrics, such as deposit decay rates, to enhance modeling accuracy. The Bank has also instituted education and training processes to provide management with information regarding emerging market forces and asset/liability-related management issues, practices and governance. Through these and other enhancements, we have significantly improved our ability to manage our interest rate risk and minimize the exposure of our earnings and capital to changes in interest rates. Pursuant to our new asset/liability management policy, we are seeking to implement the following strategies to further improve the management of our interest rate risk: ● maintaining capital levels that exceed the thresholds for well-capitalized status under federal regulations; ● maintaining a prudent level of liquidity, including through maintaining a portfolio of cash, short-term investments or investments with amortizing features; ● originating shorter term or adjustable-rate loans for portfolio, which have become somewhat more attractive to many borrowers in the current rate environment, and selling the majority of our longer term, fixed-rate residential loans; ● attempting to increase the balances of core deposits, which are less sensitive to interest rate fluctuations; ● managing our utilization of wholesale funding with borrowings from the FHLB in a prudent manner; ● managing the terms of our certificates of deposit; and ● emphasizing asset quality to maximize the level of interest-earning assets. Shortening the average term of our interest-earning assets by increasing our investments in shorter term assets, as well as originating loans with variable interest rates, helps to match the maturities and interest rates of our assets and liabilities better, thereby reducing the exposure of our net interest income to changes in market interest rates. Net Interest Income. We analyze our sensitivity to changes in interest rates through a net interest income model. Net interest income is the difference between the interest income we earn on our interest-earning assets, such as loans and securities, and the interest we pay on our interest-bearing liabilities, such as deposits and borrowings. We estimate what our net interest income would be for a 12-month period. We then calculate what the net interest income would be for the same period under the assumptions that the U.S. Treasury yield curve increases or decreases instantaneously by various basis point increments, with changes in interest rates representing immediate and permanent, parallel shifts in the yield curve. A basis point equals one-hundredth of one percent, and 100 basis points equals one percent. An increase in interest rates from 3% to 4% would mean, for example, a 100-basis point increase in the “Change in Interest Rates” column below. 30 Table of Contents The following table sets forth, as of March 31, 2025, the calculation of the estimated changes in our net interest income that would result from the designated immediate changes in the U.S. Treasury yield curve. ​ ​ ​ ​ ​ ​ ​ At March 31, 2025 Change in Interest Rates Net Interest Income Year 1 Year 1 Change from (basis points) (1) Forecast Level (Dollars in thousands) 300 ​ $ 3,141 (22.12) % 200 ​ 3,431 (14.93) % 100 ​ 3,737 (7.34) % Level ​ 4,033 — % (100) ​ 4,388 8.80 % (200) ​ 4,737 17.46 % (300) ​ 5,082 26.01 % (1) Assumes an immediate uniform change in interest rates at all maturities. The table above indicates that at March 31, 2025, we would have experienced a 14.93% decrease in net interest income in the event of an instantaneous parallel 200 basis point increase in market interest rates and a 17.46% increase in net interest income in the event of an instantaneous parallel 200 basis point decrease in market interest rates. Economic Value of Equity . We also compute amounts by which the net present value of our assets and liabilities (economic value of equity or “EVE”) would change in the event of a range of assumed changes in market interest rates. This model uses a discounted cash flow analysis and an option-based pricing approach to measure the interest rate sensitivity of net portfolio value. The model estimates the economic value of each type of asset, liability and off-balance sheet contract under the assumptions that the U.S. Treasury yield curve increases instantaneously by 100, 200 and 300 basis point increments or decreases instantaneously by 100, 200 and 300 basis point increments, with changes in interest rates representing immediate and permanent, parallel shifts in the yield curve. The following table sets forth, as of March 31, 2025, the calculation of the estimated changes in our EVE that would result from the designated immediate changes in the U.S. Treasury yield curve. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ At March 31, 2025 ​ ​ ​ ​ ​ Estimated Increase Change in Interest Rates ​ Estimated ​ (Decrease) in EVE (basis points) (1) EVE (2) Amount Percent (Dollars in thousands) 300 ​ $ 8,102 ​ $ (8,369) (50.81) % 200 ​ 10,944 ​ (5,527) (33.56) % 100 ​ 14,119 ​ (2,352) (14.28) % Level ​ 16,471 ​ n/a — % (100) ​ 21,056 ​ 4,585 27.84 % (200) ​ 24,764 ​ 8,293 50.35 % (300) ​ 28,416 ​ 11,945 72.52 % (1) Assumes an immediate uniform change in interest rates at all maturities. (2) EVE is the discounted present value of expected cash flows from assets, liabilities and off-balance sheet contracts. (3) Present value of assets represents the discounted present value of incoming cash flows on interest-earning assets. (4) EVE ratio represents EVE divided by the present value of assets. The table above indicates that at March 31, 2025, we would have experienced a 33.56% decrease in EVE in the event of an instantaneous parallel 200 basis point increase in market interest rates and a 50.35% increase in EVE in the event of an instantaneous parallel 200 basis point decrease in market interest rates. The change in EVE that we would experience in the event of an instantaneous parallel 200 basis point increase and decrease in market interest rates is 31 Table of Contents outside of the limits set forth in the Bank’s asset/liability management policy. While the Bank has developed policies and procedures that it believes will help reduce its interest rate exposure, any targeted improvement is expected to be realized gradually given the constraints imposed by the Bank’s current balance sheet composition and capital structure as well as regulatory requirements. Certain shortcomings are inherent in the methodologies used in the above interest rate risk measurements. Modeling changes require making certain assumptions that may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. The net interest income and net economic value tables presented assume that the composition of our interest-sensitive assets and liabilities existing at the beginning of a period remains constant over the period being measured and assumes that a particular change in interest rates is reflected uniformly across the yield curve regardless of the duration or repricing of specific assets and liabilities. Accordingly, although the tables provide an indication of our interest rate risk exposure at a particular point in time, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates, and actual results may differ. Interest rate risk calculations also may not reflect the fair values of financial instruments. For example, decreases in market interest rates can increase the fair values of our loans, mortgage servicing rights, deposits and borrowings. 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. In 2023, the Bank developed and implemented an improved process to project the sources and uses of funds over short- and long-term horizons, and, in concert with our asset/liability management policy, implemented guidelines to better identify potential funding gaps. Further, we have established an early warning system for measuring and monitoring liquidity, including through the establishment of early warning indicators. Our primary sources of funds are deposits, principal and interest payments on loans and securities, and proceeds from maturities of securities. We are also able to borrow from the FHLB. At March 31, 2025, we had outstanding advances of $27.8 million from the FHLB. At March 31, 2025, we had unused borrowing capacity of $43.7 million from the FHLB. At March 31, 2025, we also had a $25.0 million available line of credit with the Discount Window at the Federal Reserve Bank of Chicago. In addition, at March 31, 2025 we had a $6.0 million line of credit with a correspondent bank. We have not drawn against the Discount Window or the line of credit. 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. 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. For additional information, see the condensed consolidated statements of cash flows for the three months ended March 31, 2025 and 2024 included as part of the consolidated financial statements appearing elsewhere in this filing. 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 and current pricing strategy and regulatory restrictions, we anticipate that a significant 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. As a Wisconsin-chartered savings bank, we must maintain a net worth ratio of 6.0% (with “net worth ratio” defined under Wisconsin law as the Bank’s total liabilities subtracted from its total assets, plus unallocated general loan 32 Table of Contents loss reserves, all divided by the Bank’s total assets). At March 31, 2025 and December 31, 2024, we had a net worth ratio of 5.64% and 5.67%, respectively. At March 31, 2025 and December 31, 2024, our capital levels at the Bank level exceeded the levels required to be technically considered “well capitalized” under federal regulatory capital regulations. However, we operate under an MOU with the Department and the FDIC pursuant to which, among other things, we have agreed to achieve and maintain Tier 1 capital and total risk-based capital ratio levels above that which are required under federal regulatory capital regulations and a net worth ratio (as defined under Wisconsin law) of 6.0%. At March 31, 2025, we had Tier 1 capital equal to 6.6% of total average assets, total risk-based capital equal to 11.8% of risk-weighted assets and a net worth ratio of 5.64%. At December 31, 2024, we had Tier 1 capital equal to 6.9% of total average assets, total risk-based capital equal to 12.5% of risk-weighted assets and a net worth ratio of 5.67%. Our net worth ratio for purposes of compliance with Wisconsin law is calculated differently from the federal regulatory capital regulations in that it reflects the impact of the Bank’s unallocated general loan loss reserves. The Bank’s unallocated general loan loss reserves do not impact the calculation of the federal regulatory capital ratios. The net proceeds contributed to the Bank from the stock offering completed on September 20, 2024, have significantly increased our liquidity and capital resources. Over time, the initial level of liquidity will be reduced as net proceeds from the stock offering are used for general corporate purposes, including funding loans. Our financial condition and results of operations will be enhanced by the net proceeds from the offering, which will increase our net interest-earning assets and net interest income. However, due to the increase in equity resulting from the net proceeds raised in the offering, as well as other factors associated with the offering, our return on equity may be adversely affected for a period of time following the offering. This could negatively affect the trading price of our shares of common stock. 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 March 31, 2025, we had outstanding commitments to extend credit of $29.1 million. We anticipate that we will have sufficient funds available to meet our current lending commitments. Certificates of deposit that are scheduled to mature in one year or less from March 31, 2025 totaled $86.3 million. Management expects that a substantial portion of these time deposits will be retained. However, if a substantial portion of these time deposits is not retained, we may utilize advances from the FHLB or raise interest rates on deposits to attract new accounts, which may result in higher levels of interest expense. Our off-balance sheet credit exposures are limited to unfunded loan commitments primarily related to residential real estate loans. The unfunded commitments are evaluated on a quarterly basis. Our losses related to the unfunded commitments as of March 31, 2025 were estimated to be $128,000. We have provisioned for this exposure and recorded a reserve of $128,000 as of March 31, 2025. Contractual Obligations. In the ordinary course of our operations, we enter into certain contractual obligations. Such obligations include data processing services, operating contracts for premises and equipment, agreements with respect to borrowed funds and deposit liabilities. 33 Table of Contents Item 3.
