BANCORP, MHC AND SUBSIDIARIES Notes to Unaudited Consolidated Financial Statements Note 1: Summary of Significant Accounting Policies Organization On August 3, 2017, East Wisconsin Savings Bank (the “Bank”) converted from a mutual savings bank to a stock savings bank and is now organized in the mutual holding company structure. The Bank issued all of its outstanding stock to a mid-tier holding company, EWSB Bancorp, Inc., which is owned 100 % by a mutual holding company, Wisconsin Mutual Bancorp, MHC, (collectively the “Company”). 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 Wisconsin Mutual Bancorp, MHC and its subsidiaries, EWSB Bancorp, Inc. and 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 Wisconsin Mutual Bancorp, MHC and its subsidiaries at and for the year ended December 31, 2023 contained in the Company’s prospectus dated June 28, 2024 (the “Prospectus”), as filed with the Securities and Exchange Commission pursuant to Securities Act Rule 424(b)(3) on July 8, 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, 2023, contained in the Prospectus. 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 allowance for credit losses, valuation allowance on deferred tax assets, and fair value of securities are particularly subject to change in the near term. Actual results may differ from these estimates.

Based on our analysis of these securities, the decline in value is unrelated to credit loss and is related to changes in market interest rates since purchase, and therefore, changes in value for securities are 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 June 30, 2024. 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 June 30, 2024. Contractual maturities will differ from expected maturities for mortgage-backed securities because borrowers may have the right to call or prepay obligations without penalties. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2024 ​ ​ ​ ​ ​ Estimated Available-for-sale ​ Amortized Cost ​ Fair Value Due in one year or less $ 563,526 $ 553,097 Due after one year through five years ​ 3,696,026 ​ 3,228,234 Due after five years through ten years ​ 12,748,061 ​ 10,465,912 Due after ten years ​ 647,265 ​ 475,621 ​ ​ ​ ​ ​ ​ ​ Subtotal ​ 17,654,878 ​ 14,722,864 Mortgage-backed securities ​ 9,655,834 ​ 8,399,734 Total ​ $ 27,310,712 ​ $ 23,122,598 ​ ​ 9 Table of Contents WISCONSIN MUTUAL BANCORP, MHC AND SUBSIDIARIES Debt Securities HTM The following table summarizes the amortized cost and estimated fair value of securities held to maturity at June 30, 2024 and December 31, 2023, and the corresponding amounts of gross unrealized gains and losses. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Gross ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ Estimated June 30, 2024 ​ Cost ​ Gains ​ Losses ​ Fair Value Securities held to maturity: ​ ​ ​ ​ U.S. government sponsored agencies ​ $ 28,635,962 $ — ​ $ ( 794,749 ) ​ $ 27,841,213 U.S. Treasury securities ​ 10,522,719 — ​ ( 133,135 ) ​ 10,389,584 Total securities held to maturity ​ $ 39,158,681 $ — ​ $ ( 927,884 ) ​ $ 38,230,797 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Gross ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ Estimated December 31, 2023 ​ Cost ​ Gains ​ Losses ​ Fair Value Securities held to maturity: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government sponsored agencies ​ $ 28,223,324 ​ $ 12,819 ​ $ ( 245,870 ) ​ $ 27,990,273 U.S. Treasury securities ​ 11,827,534 ​ 3,234 ​ ( 16,213 ) ​ 11,814,555 Total securities held to maturity ​ $ 40,050,858 ​ $ 16,053 ​ $ ( 262,083 ) ​ $ 39,804,828 ​ Investment securities classified as HTM are recorded at amortized cost subject to measurement of credit losses on financial instruments, also known as Current Expected Credit Losses (CECL). 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 June 30, 2024. 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 June 30, 2024. 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. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2024 ​ ​ Amortized ​ Estimated Held-to-maturity ​ Cost ​ Fair Value Due in one year or less $ 1,465,606 $ 1,453,185 Due after one year

There were no collateral dependent loans as of June 30, 2024. 12 Table of Contents WISCONSIN MUTUAL BANCORP, MHC AND SUBSIDIARIES As of December 31, 2023, there was one collateral dependent loan totaling $ 9,888 in the marine and recreational loan segment. This loan was collateralized by a licensed recreational vehicle and had $ 4,889 in the ACL as of December 31, 2023. There were no other collateral dependent loans as of December 31, 2023. 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. ​ 13 Table of Contents WISCONSIN MUTUAL BANCORP, MHC AND SUBSIDIARIES The following tables present the credit risk profile of the Company’s loan

Note 6: Equity and Regulatory Matters 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 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. 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 June 30, 2024, that the Bank meets all applicable capital adequacy requirements. 18 Table of Contents WISCONSIN MUTUAL BANCORP, MHC AND SUBSIDIARIES As of June 30, 2024, 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 Bank’s actual capital amounts and ratios as of June 30, 2024 and December 31, 2023, 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 June 30, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Bank ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier 1 capital (to risk-weighted assets) ​ $ 15,637 ​ 10.1 % ​ 6,987 ​ ≥ 4.5 % ​ 10,093 ​ ≥ 6.5 % Tier 1 capital (to risk-weighted assets) ​ ​ 15,637 ​ 10.1 % ​ 9,317 ​ ≥ 6.0 % ​ 12,422 ​ ≥ 8.0 % Total capital (to risk-weighted assets) ​ ​ 16,805 ​ 10.8 % ​ 12,422 ​ ≥ 8.0 % ​ 15,528 ​ ≥ 10.0 % Tier 1 capital (to average assets) ​ ​ 15,637 ​ 5.9 % ​ 10,594 ​ ≥ 4.0 % ​ 13,243 ​ ≥ 5.0 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Bank ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common Equity Tier 1 capital (to risk-weighted assets) ​ $ 16,464 ​ 11.2 % ​ ≥ $ 6,634 ​ ≥ 4.5 % ​ ≥ $ 9,582 ​ ≥ 6.5 % Tier 1 capital (to risk-weighted assets) ​ 16,464 ​ 11.2 % ​ ≥ 8,845 ​ ≥ 6.0 % ​ ≥ 11,794 ​ ≥ 8.0 % Total capital (to risk-weighted assets) ​ 17,521 ​ 11.9 % ​ ≥ 11,794 ​ ≥ 8.0 % ​ ≥ 14,742 ​ ≥ 10.0 % Tier 1 capital (to average assets) ​ 16,464 ​ 6.3 % ​ ≥ 10,386 ​ ≥ 4.0 % ​ ≥ 12,982 ​ ≥ 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 8.00 % and its level of total capital to risk-weighted assets at a minimum of 11.00 % . At June 30, 2024, the Bank is not in compliance with minimum capital ratios as designated by the Board of Directors. In addition to the above minimum regulatory capital measures, the State of Wisconsin requires a savings bank to maintain a net worth ratio in an amount not less than 6 %. At June 30, 2024, the Bank’s net worth ratio of 4.31 % was not in compliance with the minimum requirement. 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. ​ 19 Table of Contents WISCONSIN MUTUAL BANCORP, MHC AND SUBSIDIARIES 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 June 30, 2024 and December 31, 2023, 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. Fair value hedge – Fair value hedges are classified as Level 2 measurements within the fair value hierarchy. The fair value measurement is based on current observable market interest rates. ​ 20 Table of Contents WISCONSIN MUTUAL BANCORP, MHC AND SUBSIDIARIES Information regarding the fair value of assets and liabilities measured at fair value on a recurring basis as of June 30, 2024 and December 31, 2023, follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Recurring Fair Value Measurements Using ​ ​ ​ ​ ​ Quoted Prices ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ in Active ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ Markets for ​ Other ​ ​ Significant ​ ​ Assets ​ Identical ​ Observable ​ ​ Unobservable ​ ​ Measured at ​ Instruments ​ Inputs ​ ​ Inputs ​ Fair Value ​ (Level 1) (Level 2) ​ (Level 3) June 30, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ ​ ​ ​ Securities available for sale: ​ ​ ​ ​ ​ ​ ​ ​ Mortgage-backed securities ​ $ 8,399,734 ​ $ — ​ $ 8,399,734 ​ $ — State and political subdivisions ​ ​ 11,930,599 ​ ​ — ​ ​ 11,930,599 ​ ​ — Corporate securities ​ ​ 2,792,265 ​ ​ — ​ ​ 2,792,265 ​ ​ — Total securities available for sale ​ $ 23,122,598 ​ $ — ​ $ 23,122,598 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair value hedge on fixed rate loans ​ $ 273,859 ​ $ — ​ $ 273,859 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ ​ ​ ​ Securities available for sale: ​ ​ ​ ​ ​ ​ ​ ​ Mortgage-backed securities ​ $ 9,040,705 ​ $ — ​ $ 9,040,705 ​ $ — State and political subdivisions ​ 12,083,045 ​ — ​ 12,083,045 ​ — Corporate securities ​ 2,824,025 ​ — ​ 2,824,025 ​ — Total securities available for sale ​ $ 23,947,775 ​ $ — ​ $ 23,947,775 ​ $ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities: ​ ​ ​ ​ Fair value hedge on fixed rate loans ​ $ 140,321 ​ $ — ​ $ 140,321 ​ $ — ​ ​ Note 8: Fair Value of Financial Instruments Financial instruments are classified within the fair value hierarchy using the methodologies described in Note 7 – Fair Value Measurements. 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. ​ 21 Table of Contents WISCONSIN MUTUAL BANCORP, MHC AND SUBSIDIARIES The carrying amounts and estimated fair values by fair value hierarchy of certain financial instruments as of June 30, 2024 and December 31, 2023, follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Estimated ​ Amount (Level 1) (Level 2) (Level 3) Fair Value June 30, 2024 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ HTM debt securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government sponsored agencies ​ $ 28,635,962 ​ $ — ​ $ 27,841,213 ​ $ — ​ $ 27,841,213 U.S. Treasury securities ​ $ 10,522,719 ​ $ 10,389,584 ​ $ — ​ $ — ​ $ 10,389,584 Loans, net ​ $ 179,765,498 ​ $ — ​ $ — ​ $ 173,031,000 ​ $ 173,031,000 Financial liabilities: ​ ​ ​ ​ ​ Interest-bearing deposits ​ $ 214,204,759 ​ $ — ​ $ 200,623,000 ​ $ — ​ $ 200,623,000 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial assets: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ HTM debt securities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. government sponsored agencies ​ $ 28,223,324 ​ $ — ​ $ 27,990,273 ​ $ — ​ $ 27,990,273 U.S. Treasury securities ​ $ 11,827,534 ​ $ 11,814,555 ​ $ — ​ $ — ​ $ 11,814,555 Loans, net ​ $ 174,315,171 ​ $ — ​ $ — ​ $ 165,086,000 ​ $ 165,086,000 Financial liabilities: ​ ​ ​ ​ ​ Interest-bearing deposits ​ $ 220,217,134 ​ $ — ​ $ 207,001,000 ​ $ — ​ $ 207,001,000 ​ ​ Note 9: Derivatives The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company primarily uses interest rate swaps as part of its interest rate risk management strategy. The aggregate fair value of the swaps are recorded in other assets or other liabilities with changes in fair value recorded as gains or losses in noninterest income or noninterest expense on the consolidated statements of income (loss). The Company utilizes interest rate swap agreements as part of its asset liability management strategy to help manage its interest rate risk position. The notional amount of the interest rate swap does not represent amounts exchanged by the parties. The amount exchanged is determined by reference to the notional amount and the other terms of the individual interest rate swap agreements. Fair Value Hedge: An interest rate swap with a notional amount totaling $ 25.0 million as of June 30, 2024 was designated as a fair value last of layer hedge for certain fixed rate prepayable loans. Note 10: Plan of Conversion On March 4, 2024, the Board of Directors of Wisconsin Mutual Bancorp, MHC adopted a plan for its conversion to a fully stock holding company structure. According to the plan, EWSB Bancorp, Inc., which is currently the mid-tier stock holding company subsidiary of Wisconsin Mutual Bancorp, MHC and owns all of East Wisconsin Savings Bank’s common stock, will be succeeded by the Company which will own all of East Wisconsin Savings Bank’s common stock after the conversion. The conversion is subject to the final approval of the Federal Reserve Board; and the Wisconsin Department of Financial Institutions and the approval of at least a majority of the votes eligible to be cast by members eligible to vote at a special meeting of members of Wisconsin Mutual Bancorp, MHC to be held on August 19, 2024. ​ 22 Table of Contents Item 2.

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 June 30, 2024, 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 Operations” in our Prospectus. 24 Table of Contents Comparison of Financial Condition at June 30, 2024 and December 31, 2023 Total Assets. Total assets increased $5.0 million, or 1.9%, to $267.5 million at June 30, 2024 from $262.6 million at December 31, 2023. The change was primarily the result of a $5.4 million increase in portfolio loans offset by a total decline of $1.7 million in investment securities balances. Other assets increased $1.2 million primarily due to the accumulated balance of costs incurred related to the stock conversion. Cash and Due from Banks and Time Deposits with Other Financial Institutions. Total cash and due from banks and time deposits with other financial institutions declined $93,000, or 1.6% to $6.0 million at June 30, 2024 from $6.1 million at December 31, 2023. The change relates to general business activity. Securities Available-for-Sale. Securities available-for-sale decreased $825,000, or 3.5%, to $23.1 million at June 30, 2024 from $23.9 million at December 31, 2023. The decrease was due to principal paydowns of $600,000 on mortgage-backed securities and a $255,000 decrease in the market value of the portfolio due to an increase in interest rates during the first six months of 2024. The proceeds from principal paydowns are utilized to manage liquidity and support loan growth. Securities Held-to-Maturity. Securities held-to-maturity decreased $892,000, or 2.2%, to $39.2 million at June 30, 2024 from $40.1 million at December 31, 2023. The decline in securities held-to-maturity was due to maturities totaling $1.5 million offset by $554,000 in amortization of unrealized losses. Loans, net. Loans, net increased $5.5 million, or 3.1%, to $179.8 million at June 30, 2024 from $174.3 million at December 31, 2023. Construction, marine and recreational vehicles, one- to four-family, home equity loans and lines of credit, and other consumer loans increased $3.4 million, $1.5 million, $884,000, $522,000 and $23,000, respectively, to $7.4 million, $32.3 million, $123.1 million, $6.7 million, and $4.1 million at June 30, 2024, respectively, as a result of loan production exceeding payoffs and amortization. These increases were partially offset by decreases to commercial, other commercial real estate, and multifamily of $386,000, $319,000 and $38,000 respectively, to $4.0 million, $2.0 million and $1.4 million at June 30, 2024, respectively. Deposits. Total deposits decreased $7.6 million or 3.3% to $222.9 million at June 30, 2024 from $230.5 million at December 31, 2023. Non-interest bearing deposits decreased $1.6 million, or 15.2%, to $8.7 million at June 30, 2024 from $10.3 million at December 31, 2023. Total interest-bearing deposits other than time deposits decreased approximately $11.3 million, or 9.8%, to $104.4 million at June 30, 2024, from $115.7 million at December 31, 2023. Certificates of deposit balances increased $5.3 million, or 5.1%, to $109.8 million at June 30, 2024, from $104.5 million at December 31, 2023. The deposit mix changes are consistent with industry trends as consumers are transitioning to higher yielding term deposits in the current interest rate environment. Borrowings. We had $31.1 million of borrowings at June 30, 2024 as compared to $19.0 million at December 31, 2023. We borrowed $17.0 million from the Federal Reserve Bank under its Bank Term Funding Program in January 2024. These funds were utilized to pay down borrowings at the FHLB. During the second quarter of 2024, the Company obtained additional advances from the FHLB totaling approximately $7.7 million. At June 30, 2024, the Company has total outstanding advances from the FHLB of approximately $13.7 million. The additional advances were used to fund portfolio loan growth and offset the decline in deposit balances. Equity. Total equity decreased $621,000, or 5.4%, to $10.9 million at June 30, 2024 from $11.5 million at December 31, 2023, due to a decrease in retained earnings of $840,000, which resulted from the net loss incurred for the six months ended June 30, 2024, partially offset by a decrease in accumulated other comprehensive loss of $220,000. ​ 25 Table of Contents Comparison of Operating Results for the Three Months Ended June 30, 2024 and 2023 Net Income/(Loss). We recorded a net loss of $463,000 for the three months ended June 30, 2024, compared to a net loss of $215,000 for the three months ended June 30, 2023, a change of $248,000 year-over-year. The increase in our net loss year-over-year resulted primarily from a $396,000 decline in net interest income due to increased funding costs and an increase of $55,000 in total noninterest expense, partially offset by an increase of $104,000 in noninterest income. Interest Income. Interest income increased $176,000, or 7.9%, to $2.4 million for the three months ended June 30, 2024, from $2.2 million for the three months ended June 30, 2023, due to a $185,000 increase in interest and fees on loans. The increase in interest and fees on loans was primarily due to an increase of 44 basis points in the weighted average yield on the loan portfolio to 4.69% for the three months ended June 30, 2024 from 4.25% for the same period in 2023. Interest income on securities and other investments declined $9,000 to $317,000 for the three months ended June 30, 2024 primarily due to a $2.6 million decline in average balance of available for sale investment securities year-over-year. The average balance decline was related to security maturities in the second quarter of 2024. Interest Expense. Total interest expense increased $572,000, or 56.4%, to $1.6 million for the three months ended June 30, 2024, from $1,014,000 for the three months ended June 30, 2023. Interest expense on deposits increased $443,000, or 53.1%, to $1.3 million for the three months ended June 30, 2024 from $834,000 for the three months ended June 30, 2023, due primarily to an increase in the weighted average rate paid on certificates of deposit of 152 basis points to 4.36% for the three months ended June 30, 2024 from 2.84% for the three months ended June 30, 2023, combined with an increase in the average balance of such deposits of $7.0 million year-over-year and a $12.3 million decrease in the average balance of lower cost money market accounts year-over-year. Interest expense on borrowed funds increased $129,000, or 71.8%, to $309,000 for the three months ended June 30, 2024, from $180,000 for the three months ended June 30, 2023. The rate paid on borrowed funds increased 163 basis points to 4.62% for the three months ended June 30, 2024, from 2.99% for the three months ended June 30, 2023 while the average balance of borrowed funds increased $2.7 million, or 11.2%, to $26.9 million for the three months ended June 30, 2024 from $24.2 million for the three months ended June 30, 2023. The increase in the average balance was generally related to the measured use of borrowings to offset deposit outflows and to support the increase in the loan portfolio. Net Interest Income. Net interest income decreased $396,000, or 32.7%, to $816,000 for the three months ended June 30, 2024 from $1.2 million for the three months ended June 30, 2023, primarily due to a decrease in the interest rate spread to 1.28% for the three months ended June 30, 2024 from 1.86% for the three months ended June 30, 2023 and a decrease in the net interest margin to 1.31% for the three months ended June 30, 2024, from 1.89% for the three months ended June 30, 2023. The decreases in the interest rate spread and the net interest margin were primarily due to an increase in the rates paid on interest-bearing liabilities in conjunction with an increase in other borrowings, partially offset by a 39 basis point increase in the weighted average yield on our interest earning assets. Provision for Credit Losses. Based on management’s analysis of the adequacy of the ACL, a provision of $120,000 was made to the ACL for the three months ended June 30, 2024, compared to $109,000 for the same period in 2023. 26 Table of Contents Noninterest Income. Noninterest income increased $104,000, or 32.4%, to $426,000 for the three months ended June 30, 2024 from $322,000 for the three months ended June 30, 2023. The increase resulted primarily from a $12,000 increase in mortgage banking revenue due to increased activity and an $87,000 gain on an interest rate swap entered into late in 2023. These increases were partially offset on a comparative basis as a $10,000 gain on other real estate owned was recognized in the three months ended June 30, 2023 while there was no such gain in the 2024 period. The table below sets forth our noninterest income for the quarters ended June 30, 2024 and 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ ​ ​ ​ ​ ​ June 30, ​ Change ​ 2024 2023 Amount Percent ​ ​ ​ Service charges on deposit accounts ​ $ 29,972 ​ $ 17,749 ​ $ 12,223 68.9 % Interchange income ​ 62,205 ​ 63,429 ​ (1,224) (1.9) % Mortgage banking income ​ 114,586 ​ 102,737 ​ 11,849 11.5 % Increase in cash value of life insurance ​ 59,493 ​ 53,277 ​ 6,216 11.7 % Gain on sale of repossessed assets ​ — ​ 9,368 ​ (9,368) (100.0) % Gain on interest rate swap ​ ​ 87,155 ​ — ​ 87,155 — % Other ​ 72,921 ​ 75,549 ​ (2,628) (3.5) % Total noninterest income ​ $ 426,332 ​ $ 322,109 ​ $ 104,223 32.4 % ​ Noninterest Expense. Noninterest expense increased $55,000, or 3.2%, to $1.8 million for the three months ended June 30, 2024 from $1.7 million for the three months ended June 30, 2023. Data processing and information technology expense increased $55,000 due to the implementation of additional network services and an increase in other noninterest expense was due in large part to additional accounting and consulting services. Salary and related benefits expense increased $30,000. Our other noninterest expense for the three months ended June 30, 2023 was impacted by a one-time expense that we incurred related to the proposed acquisition of another mutual institution that was later terminated. The increase in noninterest expense when comparing the two periods was partially offset by a decrease in net occupancy expense for the three months ended June 30, 2024, which resulted primarily from the closing of one of our branch offices in the third quarter of 2023 combined with additional operational efficiencies that we implemented in 2023. FDIC insurance premiums decreased $10,000 due a decline in deposits during the quarter.

Our benefit for income taxes increased $110,000 to a benefit of $199,000 for the three months ended June 30, 2024, from a benefit of $89,000 for the three months ended June 30, 2023 due to an increase in loss before provision (benefit from) income taxes. 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.

We recorded a net loss of $840,000 for the six months ended June 30, 2024, compared to a net loss of $409,000 for the six months ended June 30, 2023, a change of $431,000 year-over-year. The increase in our net loss year-over-year resulted primarily from a $964,000 decline in net interest income due to increased funding costs and an increase of $78,000 in total noninterest expense, partially offset by a decrease of $106,000 in the provision for credit losses, an increase of $302,000 in noninterest income and an increase in of $202,000 in the benefit for income taxes. Interest Income. Interest income increased $274,000 or 6.2%, to $4.7 million for the six months ended June 30, 2024, from $4.4 million for the six months ended June 30, 2023, due to a $362,000 increase in interest and fees on loans. The increase in interest and fees on loans was primarily due to an increase of 42 basis points in the weighted average yield on the loan portfolio to 4.64% for the six months ended June 30, 2024 from 4.20% for the same period in 2023. Interest income on securities and other investments declined $89,000 to $636,000 for the six months ended June 30, 2024 primarily due to a $5.7 million decline in average balance of available for sale investment securities year-over-year. The average balance decline was related to security maturities during the six months ended June 30, 2024. 30 Table of Contents Interest Expense. Total interest expense increased $1.2 million, or 67.9%, to $3.1 million for the six months ended June 30, 2024, from $1.8 million for the six months ended June 30, 2023. Interest expense on deposits increased $974,000, or 64.2%, to $2.5 million for the six months ended June 30, 2024 from $1.5 million for the six months ended June 30, 2023, due primarily to an increase in the weighted average rate paid on certificates of deposit of 171 basis points to 4.27% for the six months ended June 30, 2024 from 2.56% for the six months ended June 30, 2023, combined with an increase in the average balance of such deposits of $7.3 million year-over-year and a $13.9 million decrease in the average balance of lower cost money market accounts year-over-year. Interest expense on borrowed funds increased $265,000, or 86.2%, to $572,000 for the six months ended June 30, 2024, from $307,000 for the six months ended June 30, 2023. The rate paid on borrowed funds increased 160 basis points to 4.58% for the six months ended June 30, 2024, from 2.98% for the six months ended June 30, 2023 while the average balance of borrowed funds increased $4.3 million, or 20.8%, to $25.1 million for the six months ended June 30, 2024 from $20.8 million for the six months ended June 30, 2023. The increase in the average balance was generally related to the measured use of borrowings to offset deposit outflows and to support the increase in the loan portfolio. Net Interest Income. Net interest income decreased $964,000, or 37.0%, to $1.6 million for the six months ended June 30, 2024 from $2.6 million for the six months ended June 30, 2023, primarily due to a decrease in the interest rate spread to 1.29% for the six months ended June 30, 2024 from 2.00% for the six months ended June 30, 2023 and a decrease in the net interest margin to 1.33% for the six months ended June 30, 2024, from 2.03% for the six months ended June 30, 2023. The decreases in the interest rate spread and the net interest margin were primarily due to an increase in the rates paid on interest-bearing liabilities in conjunction with an increase in other borrowings, partially offset by a 35 basis point increase in the weighted average yield on our interest earning assets. Provision for Credit Losses. Based on management’s analysis of the adequacy of the ACL, a provision of $120,000 was made to the ACL for the six months ended June 30, 2024, compared to $226,000 for the same period in 2023. Noninterest Income. Noninterest income increased $302,000, or 50.9%, to $895,000 for the six months ended June 30, 2024 from $593,000 for the six months ended June 30, 2023. The increase resulted primarily from a $67,000 increase in mortgage banking revenue due to increased activity, a $173,000 gain on an interest rate swap entered into late in 2023, and an increase of $117,000 in other noninterest income. These increases were partially offset on a comparative basis as a $71,000 gain on other real estate owned was recognized in the six months ended June 30, 2023 while there was no such gain in the 2024 period. The table below sets forth our noninterest income for the quarters ended June 30, 2024 and 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ ​ ​ ​ ​ ​ June 30, ​ Change ​ 2024 2023 Amount Percent ​ ​ ​ Service charges on deposit accounts ​ $ 40,352 ​ $ 31,155 ​ $ 9,197 29.5 % Interchange income ​ 119,344 ​ 123,191 ​ (3,847) (3.1) % Mortgage banking income ​ 229,152 ​ 162,082 ​ 67,070 41.4 % Increase in cash value of life insurance ​ 113,694 ​ 103,344 ​ 10,350 10.0 % Gain on sale of other real estate owned ​ — ​ 71,012 ​ (71,012) (100.0) % Gain on interest rate swap ​ ​ 173,445 ​ — ​ 173,445 — % Other ​ 219,104 ​ 102,408 ​ 116,696 114.0 % Total noninterest income ​ $ 895,091 ​ $ 593,192 ​ $ 301,899 50.9 % ​ 31 Table of Contents Noninterest Expense. Noninterest expense increased $78,000, or 2.2%, to $3.6 million for the six months ended June 30, 2024 from $3.5 million for the six months ended June 30, 2023. Data processing and information technology expense increased $82,000 due to the implementation of additional network services and an increase in other noninterest expense was due in large part to additional accounting and audit-related services. Salary and related benefits increased $23,000. The increase in noninterest expense when comparing the two periods was partially offset by a decrease in net occupancy expense for the six months ended June 30, 2024, which resulted primarily from the closing of one of our branch offices in the third quarter of 2023 combined with additional operational efficiencies that we implemented in 2023. The table below sets forth our noninterest expense for the quarters ended June 30, 2024 and 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Six Months Ended ​ ​ ​ ​ ​ ​ June 30, ​ Change ​ 2024 2023 Amount Percent ​ ​ ​ Salaries and related benefits $ 2,048,383 $ 2,025,783 $ 22,600 1.1 % Occupancy expense, net ​ ​ 333,659 ​ ​ 393,552 ​ ​ (59,893) (15.2) % Data processing ​ 564,663 ​ 482,855 ​ 81,808 16.9 % Advertising ​ 84,353 ​ 88,888 ​ (4,535) (5.1) % FDIC insurance premiums ​ 151,483 ​ 155,006 ​ (3,523) (2.3) % Other ​ 434,091 ​ 393,020 ​ 41,071 10.5 % Total noninterest expense $ 3,616,632 ​ $ 3,539,104 ​ $ 77,528 2.2 % ​ Income Tax Expense. Our benefit for income taxes increased $202,000 to a benefit of $361,000 for the six months ended June 30, 2024, from a benefit of $159,000 for the six months ended June 30, 2023 due to an increase in loss before provision (benefit from) income taxes. Management of Market Risk General . 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, Senior Vice President of Finance, 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. 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. Over the last year, 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; 32 Table of Contents ● 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. We recently entered into an interest rate swap for the purpose of mitigating interest rate risk, but it is not our policy to enter into such transactions on a regular basis. The interest rate swap was designated as a fair value last of layer hedge for certain fixed-rate prepayable loans and had a notional value of $25.0 million at June 30, 2024. 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. The following table sets forth, as of June 30, 2024, 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 June 30, 2024 Change in Interest Rates Net Interest Income Year 1 Year 1 Change from (basis points) (1) Forecast Level (Dollars in thousands) 300 ​ $ (396) (12.08) % 200 ​ (243) (7.40) % 100 ​ (107) (3.27) % Level ​ — — % (100) ​ 70 2.14 % (200) ​ 127 3.87 % (300) ​ 173 5.26 % (1) Assumes an immediate uniform change in interest rates at all maturities. The table above indicates that at June 30, 2024, we would have experienced a 7.40% decrease in net interest income in the event of an instantaneous parallel 200 basis point increase in market interest rates and a 3.87% increase in net interest income in the event of an instantaneous parallel 200 basis point decrease in market interest rates. 33 Table of Contents 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 June 30, 2024, 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 June 30, 2024 ​ ​ ​ ​ ​ Estimated Increase Change in Interest Rates ​ Estimated ​ (Decrease) in EVE (basis points) (1) EVE (2) Amount Percent (Dollars in thousands) 300 ​ $ 9,837 ​ $ (10,166) (50.82) % 200 ​ 13,167 ​ (6,836) (34.18) % 100 ​ 16,596 ​ (3,407) (17.03) % Level ​ 20,003 ​ n/a — % (100) ​ 22,468 ​ 2,465 12.32 % (200) ​ 25,554 ​ 5,551 27.75 % (300) ​ 28,702 ​ 8,699 43.49 % (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 June 30, 2024, we would have experienced a 34.18% decrease in EVE in the event of an instantaneous parallel 200 basis point increase in market interest rates and a 27.75% increase in EVE in the event of an instantaneous parallel 200 basis point decrease in market interest rates. The decrease in EVE that we would experience in the event of an instantaneous parallel 200 basis point increase in market interest rates is outside of the limits set forth in the Bank’s new 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. See “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Management of Market Risk” and “Supervision and Regulation—Informal Agreements with Regulators” included in the Prospectus dated June 28, 2024. 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. 34 Table of Contents 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 June 30, 2024, we had outstanding advances of $13.7 million from the FHLB. At June 30, 2024, we had unused borrowing capacity of $52.2 million from the FHLB. At June 30, 2024, 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 June 30, 2024 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. Additionally, we participated in the Federal Reserve Board’s BTFP in January 2024 and had a $17.0 million outstanding borrowing at June 30, 2024. 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 six months ended June 30, 2024 and 2023 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% (with “net worth ratio” defined under Wisconsin law as the Bank’s total liabilities subtracted from its total assets, plus unallocated general loan loss reserves, all divided by the Bank’s total assets). At June 30, 2024 and December 31, 2023, we had a net worth ratio of 4.31% and 4.50%, respectively. At June 30, 2024 and December 31, 2023, 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%. At June 30, 2024, we had Tier 1 capital equal to 5.9% of total average assets, total risk-based capital equal to 10.8% of risk-weighted assets and a net worth ratio of 4.31%. At December 31, 2023, we had Tier 1 capital equal to 6.3% of total average assets, total risk-based capital equal to 11.9% of risk-weighted assets and a net worth ratio of 4.50%. 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. Our pro forma regulatory capital ratios, including the pro forma net worth ratio, after giving effect to the sale of shares of common stock in the offering, are set forth under “Historical and Pro Forma Regulatory Capital Compliance” included in the Prospectus dated June 28, 2024. The net proceeds from the planned offering contributed to the Bank will significantly increase our liquidity and capital resources. Over time, the initial level of liquidity will be reduced as net proceeds from the stock offering are used 35 Table of Contents 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 will be adversely affected following the offering. See “Historical and Pro Forma Regulatory Capital Compliance” and “Risk Factors—Risks Related to the Offering” included in the Prospectus dated June 28, 2024. 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 June 30, 2024, we had outstanding commitments to originate loans of $18.1 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 June 30, 2024 totaled $89.9 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 June 30, 2024 were estimated to be zero; as a result, the ACL at such date did not include an amount for off-balance sheet credit exposures. 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. Item 3. Quantitative and Qualitative Disclosures About Market Risk Not applicable, as the Company is a smaller reporting company. Item 4. Controls and Procedures An evaluation was performed under the supervision and with the participation of the Company’s management, including the Chief Executive Officer and the Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (as defined in Rule 13a-15(e) promulgated under the Securities and Exchange Act of 1934, as amended) as of June 30, 2024.
