Organization, Consolidation and Presentation of Financial Statements [Abstract]
Nature of Operations and Basis of Presentation	NOTE 1 – NATURE OF OPERATIONS AND BASIS OF PRESENTATION 1895 Bancorp of Wisconsin, Inc., a Maryland corporation (the “Company” or “New 1895 Bancorp”) was formed to serve as the stock holding company for PyraMax Bank, FSB (the “Bank”) as part of the mutual-to-stock conversion of 1895 Bancorp of Wisconsin, MHC. Upon completion of the conversion, which occurred on July 14, 2021, 1895 Bancorp of Wisconsin, MHC and 1895 Bancorp of Wisconsin, a federal corporation (“Old 1895 Bancorp”), ceased to exist and New 1895 Bancorp became the successor corporation to Old 1895 Bancorp. The conversion was accomplished by the merger of 1895 Bancorp of Wisconsin, MHC with and into Old 1895 Bancorp followed by the merger of Old 1895 Bancorp with and into New 1895 Bancorp. The shares of New 1895 Bancorp common stock that were offered for sale in connection with the conversion represented the majority ownership interest in Old 1895 Bancorp owned by 1895 Bancorp of Wisconsin, MHC. On July 14, 2021, public stockholders of Old 1895 Bancorp received 1.3163 shares of common stock of New 1895 Bancorp in exchange for each of their shares of Old 1895 Bancorp common stock. The shares of Old 1895 Bancorp common stock owned by 1895 Bancorp of Wisconsin, MHC were canceled at that time. The conversion and offering were completed on July 14, 2021, and New 1895 Bancorp was organized as a fully public stock holding company, with 100 % of the common stock being held by the public. The consolidated financial statements and other financial information contained in these consolidated financial statements are for New 1895 Bancorp. The cost of the reorganization and the issuing of the common stock totaling $ 2.0 million were deferred and deducted from the sales proceeds of the offering. PyraMax Bank is a stock savings bank headquartered in Greenfield, Wisconsin. PyraMax Bank operates as a full-service financial institution, providing a full range of financial services, including the granting of commercial, residential, and consumer loans and acceptance of deposits from individual customers and small businesses in the metropolitan Milwaukee, Wisconsin area. PyraMax Bank is subject to competition from other financial and nonfinancial institutions providing financial products. In addition, PyraMax Bank is subject to the regulations of certain regulatory agencies and undergoes periodic examination by those regulatory agencies. The accompanying unaudited interim consolidated financial statements and the notes thereto have been prepared in accordance with generally accepted accounting principles in the United States (“GAAP”). In the opinion of management, the accompanying unaudited interim consolidated financial statements contain all normal recurring adjustments necessary to present fairly the financial position, results of operations, changes in stockholders' equity and cash flows as of and for the periods presented. Certain amounts from prior periods have been reclassified to conform with current period presentation. The accompanying unaudited consolidated financial statements and related notes should be read in conjunction with the audited annual consolidated financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2022, as filed with the Securities and Exchange Commission on March 30, 2023. In preparing financial statements in conformity with GAAP, management is required to make estimates and assumptions that affect the reported amounts of assets and liabilities as of the date of the balance sheet, and reported amounts of revenues and expenses during the reporting period. Material estimates that are particularly susceptible to significant change in the near term relate to the determination of the allowance for credit losses, the fair value of investment securities, financial instruments and mortgage servicing rights, and the valuation of deferred income tax assets. Actual results could differ from those estimates. On April 5, 2012, the Jumpstart Our Business Startups Act (the “JOBS Act”) was signed into law. The JOBS Act contains provisions that, among other things, reduce certain reporting requirements for qualifying public companies and define an “emerging growth company.” As an emerging growth company, the Company may delay adoption of new or revised financial accounting standards until such date that the standards are required to be adopted by non-issuer companies. If such standards would not apply to non-issuer companies, no deferral would be applicable. The Company intends to take advantage of the benefits of the extended transition periods allowed under the JOBS Act. Accordingly, the Company’s financial statements may not be comparable to those of public companies that adopt new or revised financial accounting standards as of an earlier date. The effective dates of the recent accounting standards in Note 2 reflect those that relate to non-issuer companies. NOTE 1 – NATURE OF OPERATIONS AND BASIS OF PRESENTATION (continued) Subsequent Events Management has reviewed the Company's operations for potential disclosure or financial statement impacts related to events occurring after March 31, 2023, but prior to the release of the unaudited consolidated financial statements contained in this quarterly report on Form 10-Q were issued. On May 4, 2023, the Company announced that it had adopted its second stock repurchase program to be implemented upon completion of its existing stock repurchase program. Under the new repurchase program, which is subject to regulatory non-objection, the Company may repurchase up to 10 % of its current outstanding shares. Following receipt of regulatory non-objection, repurchases are expected to commence upon completion of the existing stock repurchase program, which has 9,945 shares remaining to be repurchased. For additional information, refer to Form 8-K filed by the Company on May 4, 2023. There were no additional subsequent event disclosures or financial statement impacts related to events occurring after March 31, 2023 that warranted adjustment to or disclosure in these unaudited consolidated financial statements.

Significant Accounting Policies

Accounting Policies [Abstract]
Significant Accounting Policies	NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES On January 1, 2023, we adopted ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments ("ASU 2016-13"), using the modified retrospective approach, as further described in the section below titled Recently Adopted Accounting Standards . Adoption of the standard resulted in changes to our available-for-sale securities and allowance for credit losses policies, as presented below. Refer to Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K regarding additional significant accounting policies, including accounting policies in effect prior to the adoption of ASU 2016-13. Credit Losses for Available-for-Sale Debt Securities For available-for-sale ("AFS") debt securities where fair value is less than amortized cost, the security is considered impaired when amounts are deemed uncollectible or when the Company intends, or more likely than not will be required, to sell the AFS debt security before recovery of the amortized cost basis. On a quarterly basis the Company evaluates the AFS debt securities for impairment. Securities that are in an unrealized loss position are reviewed to determine if a securities credit loss exists based on certain quantitative and qualitative factors. The primary factors considered in evaluating whether an impairment exists include: (a) the extent to which the fair value is less than the amortized cost basis, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments, and (d) whether the Company intends to sell the security and whether it is more likely than not that the Company will not be required to sell the security. If a determination is made that an AFS debt security is impaired, the Company will estimate the amount of the unrealized loss that is attributable to credit and all other non-credit related factors. The credit related component will be recognized as a provision for credit losses on securities through an allowance for credit losses. The provision for credit losses on securities will be limited to the difference between the security’s amortized cost basis and fair value. Any future changes may be reversed, limited to the amount previously expensed, in the period they occur. The non-credit related component will be recorded as an adjustment to accumulated other comprehensive income, net of tax. Allowance for Credit Losses Under the current expected credit loss (“CECL”) model, the allowance for credit losses ("ACL") on financial assets is a valuation allowance estimated at each balance sheet date in accordance with GAAP that is deducted from the financial assets’ amortized cost basis to present the net amount expected to be collected on the financial assets. The CECL model also applies to certain off-balance sheet credit exposures. The Company estimates the allowance for credit losses on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to write-off accrued interest receivable by reversing interest income at the time of this determination. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis and therefore excludes it from the measurement of the allowance for credit losses. NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES (continued) Expected credit losses are reflected in the allowance for credit losses through a charge to provision for credit losses. The Company’s estimate of the allowance for credit losses reflects credit losses currently expected over the remaining contractual life of the assets. When the Company deems all or a portion of a financial asset to be uncollectible, the appropriate amount is written off and the allowance for credit losses is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible. When available information confirms that specific financial assets, or portions thereof, are uncollectible, these amounts are charged off against the allowance for credit losses. Subsequent recoveries, if any, are credited to the allowance for credit losses when received. The Company measures the allowance for credit losses of financial assets on a collective portfolio segment basis when the financial assets share similar risk characteristics. The Company has identified the following portfolio segments of financial assets with similar risk characteristics for measuring expected credit losses: commercial real estate, residential real estate – first mortgage, residential real estate – construction, consumer – home equity and lines of credit and other consumer loans. The Company further segments the commercial loan portfolios by risk rating and the residential and consumer loan portfolios by delinquency. The Company utilizes the weighted average maturity (WARM) methodology to measure the ACL. This methodology incorporates both quantitative and qualitative information to assess lifetime expected credit losses at the portfolio segment level. The quantitative component includes the calculation of loss rates that are based on historical lookback periods. The Company calculates a loss rate based on historical loan level loss experience for portfolio segments with similar risk characteristics. The historical loss rate is adjusted for select macroeconomic variables that consider both historical trends as well as forecasted trends. The Company measures expected credit losses of these financial assets by applying loss rates to the amortized cost basis of each asset taking into consideration amortization, prepayment and default assumptions. The Company considers qualitative adjustments to expected credit loss estimates for information not already captured in the loss estimation process. Qualitative factor adjustments may increase or decrease management’s estimate of expected credit losses. Adjustments will not be made for information that has already been considered and included in the quantitative component. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data, changes in loan composition, performance trends, regulatory changes, uncertainty of macroeconomic forecasts, and other asset specific risk characteristics. Collateral Dependent Financial Assets For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable and where the borrower is experiencing financial difficulty, the allowance for credit losses is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. Fair value is generally calculated based on the value of the underlying collateral less estimated costs to sell. Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial assets include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The Company’s exposure to loan credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded. The Company records an allowance for credit losses on off-balance sheet credit exposures through a charge to provision for loan losses for off-balance sheet credit exposures. The allowance for credit losses on off-balance sheet credit exposures is estimated by portfolio segment at each balance sheet date under the CECL model using the same methodologies as portfolio loans, taking into consideration management’s assumption of the likelihood that funding will occur, and is included in other liabilities on the Company’s Consolidated Balance Sheets. NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES (continued) Recently Adopted Accounting Standards ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326) . ASU 2016-13 requires organizations to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which eliminates the accounting guidance for troubled debt restructurings by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. In addition, ASU 2022-02 requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses . The Company adopted ASU 2016-13 and ASU 2022-02 as of January 1, 2023 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures . The adoption of ASU 2016-13 resulted in an initial increase of $ 412,000 to the allowance for credit losses for loans and the establishment of a $ 665,000 allowance for credit losses for unfunded loan commitments. The allowance for credit losses for unfunded loan commitments is included in other liabilities on the Company's Consolidated Balance Sheets. The after-tax cumulative-effect adjustment of $ 783,000 was recorded in retained earnings as of January 1, 2023.

The amortized costs and fair values of available-for-sale securities, by contractual maturity, are shown below. Actual maturities may differ from contractual maturities because issuers may have the right to call or prepay obligations with or without call or prepayment penalties. In addition, expected maturities will differ from contractual maturities for mortgage-backed securities and asset-backed securities, as the expected repayment terms may be less than the underlying mortgage pool contractual maturities. Therefore, these securities are not included in the maturity categories in the maturity summary below.

These unrealized losses relate principally to changes in interest rates and were not caused by changes in the financial condition of the issuers, the quality of any underlying assets or applicable credit enhancements. In analyzing whether unrealized losses on debt securities are other-than-temporary, management considers whether the securities are issued by a government body or agency, whether a 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. As management has the intent and ability to hold these debt securities to projected recovery, none of these declines are deemed to be other-than-temporary.

Loans	NOTE 4 – LOANS Major classifications of loans, reported at amortized cost, are summarized as follows: March 31, December 31, (in thousands) Commercial: Real estate $ 215,026 $ 210,858 Land development — — Other 45,288 43,708 Residential real estate: First mortgage 88,792 85,444 Construction 2,261 3,248 Consumer: Home equity and lines of credit 18,091 18,590 Other 84 99 Subtotal (1) 369,542 361,947 Net deferred loan costs 853 830 Allowance for credit losses for loans ( 3,693 ) ( 3,203 ) Loans, net $ 366,702 $ 359,574 (1) Totals do not include accrued interest receivable, which were $ 894,000 and $ 874,000 at March 31, 2023 and December 31, 2022, respectively, which are recorded separately on the Company’s Consolidated Balance Sheets. Deposit accounts in an overdrawn position and reclassified as loans totaled $ 30,000 and $ 98,000 at March 31, 2023 and December 31, 2022, respectively. The Company provides several types of loans to its customers, including commercial, residential, construction and consumer loans. Significant loan concentrations are considered to exist for a financial institution when there are amounts loaned to one borrower or to multiple borrowers engaged in similar activities that would cause them to be similarly impacted by economic or other conditions. While the Company’s credit risks are geographically concentrated within the metropolitan Milwaukee, Wisconsin area, there are no concentrations with individual borrowers or groups of related borrowers. During the normal course of business, the Company may transfer a portion of a loan as a participation loan to another financial institution in order to manage portfolio risk. In order to be eligible for sales treatment, all cash flows from the loan must be divided proportionately, and rights of each loan holder must have the same priority, the loan holders must have no recourse to the transferor other than standard representations and warranties, and no loan holder can have the right to pledge or exchange the entire loan. As of March 31, 2023 and December 31, 2022, respectively, the Company had transferred $ 30.1 million and $ 30.3 million in participation loans which were eligible for sales treatment to other financial institutions, all of which continue to be serviced by the Company. NOTE 4 – LOANS (continued) A summary of activity in the allowance for credit losses for loans and the allowance for credit losses for unfunded loan commitments for the three months ended March 31, 2023 and in the allowance for loan losses for the three months ended March 31, 2022, is presented below: Commercial Residential Consumer Total (in thousands) Three months ended March 31, 2023 Allowance for credit losses for loans Beginning balance $ 1,944 $ 752 $ 507 $ 3,203 Provision for credit losses 54 21 — 75 CECL Adoption Adjustment (1) 666 75 ( 329 ) $ 412 Loans charged-off — — ( 6 ) ( 6 ) Recoveries 5 — 4 9 Ending balance $ 2,669 $ 848 $ 176 $ 3,693 Allowance for credit losses for unfunded loan commitments (2) Beginning balance $ — $ — $ — $ — Provision for credit losses — — — — CECL Adoption Adjustment (1) 640 25 — $ 665 Loans charged-off — — — — Recoveries — — — — Ending balance $ 640 $ 25 $ — $ 665 Total Allowance for credit losses for loans and unfunded loan commitments $ 3,309 $ 873 $ 176 $ 4,358 Three months ended March 31, 2022 Allowance for loan losses Beginning balance $ 1,657 $ 745 $ 456 $ 2,858 Provision for loan losses 105 — — 105 Loans charged-off — — ( 3 ) ( 3 ) Recoveries 52 — 5 57 Ending balance $ 1,814 $ 745 $ 458 $ 3,017 (1) On January 1, 2023, the Company adopted ASU 2016-13 ("CECL"). See Note 2 for additional information regarding the adoption of ASU 2016-13. (2) The allowance for credit losses for unfunded loan commitments is included in other liabilities on the Company's Consolidated Balance Sheets. NOTE 4 – LOANS (continued) The provision for credit losses is determined by the Company as the amount that is to be added to the ACL accounts to bring the ACL to a level that, in management's judgment, is necessary to absorb expected credit losses over the lives of the respective financial instruments. The following table presents the components of the provision for credit losses: Three months ended March 31, 2023 2022 (in thousands) Provision for credit losses for: Loans $ 75 $ 105 Unfunded loan commitments — N/A Total $ 75 $ 105 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. The credit quality indicators for commercial real estate and other commercial loans are based on the following 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. • Watch and 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 such that collectability of the contractual loan payments is unlikely. Residential real estate and consumer loans are generally evaluated based on whether or not the loan is performing or in nonaccrual status. Refer to Note 1 to the Consolidated Financial Statements in our 2022 Annual Report on Form 10-K, filed with the SEC on March 30, 2023, for additional information on our nonaccrual policy.

During the three months ended March 31, 2023, there was no interest earned on nonaccrual loans and no accrued interest was reversed on nonaccrual loans. At March 31, 2023, the Company held loans that were individually evaluated for impairment due to financial difficulties experienced by the borrower and for which the repayment, on the basis of our assessment, is expected to be provided substantially through the sale or operation of the collateral. The ACL for these collateral dependent loans is primarily based on the fair value of the underlying collateral at the reporting date. The following describes the type of collateral that secure collateral dependent loans: • Commercial real estate loans are primarily secured by office and industrial buildings and warehouses. • Commercial and industrial loans are primarily secured by accounts receivable, inventory and equipment. • One-to-four-family mortgages are primarily secured by first liens on residential real estate. • Home equity loans are primarily secured by first and junior loans on residential real estate.

The model incorporates various assumptions such as discount rates, prepayment speeds and ancillary income and servicing costs. As of March 31, 2023 , the model used discount rates ranging from 10.1 % to 13 %, and prepayment speeds ranging from 7.0 % to 38.8 %, both of which were based on market data from independent organizations. As of March 31, 2022 the model used discount rates ranging from 10 % to 13.5 %, and prepayment speeds ranging from 9.6 % to 35.8 %. The following table summarizes the estimated future amortization expense for mortgage servicing rights for the annual periods indicated. The projections of amortization expense are based on existing asset balances as of March 31, 2023. The actual amortization expense the Company recognizes in any given period may vary significantly depending on changes in interest rates, market conditions and regulatory requirements.

The Company maintains a master contract agreement with the FHLB, which provides for borrowing up to the lesser of 22.22 times the value of the FHLB stock owned, a determined percentage of the book value of the Company’s qualifying real estate loans, or a determined percentage of the Company’s assets. The FHLB provides both fixed and floating rate advances. Floating rates are tied to short-term market rates of interest such as the Secured Overnight Financing Rate ("SOFR"), federal funds or Treasury bill rates. FHLB advances are subject to a prepayment penalty if they are repaid prior to maturity. The Company has pledged qualifying real estate and commercial and industrial loans with collateral values of approximately $ 164.1 million at March 31, 2023 and $ 172.4 million at December 31, 2022. FHLB advances were also secured by approximately $ 4.8 million and $ 3.4 million of FHLB stock held by the Company as of March 31, 2023 and December 31, 2022 , respectively. The Company’s available and unused portion of this borrowing agreement totaled $ 71.2 million and $ 100.0 million as of March 31, 2023 and December 31, 2022, respectively. Additional borrowing would require additional stock purchase. Additionally, at March 31, 2023 we had a $ 15.0 million federal funds rate line of credit with the BMO Harris Bank, none of which was drawn at March 31, 2023 . The Company also had an $ 8.8 million line of credit at the Federal Reserve based on pledged commercial real estate loans of approximately $ 11.8 million at March 31, 2023 . The Company had no t drawn on the Federal Reserve line as of March 31, 2023. We also have the ability to participate in the Federal Reserve's new Bank Term Funding Program as needed.

Income Tax Disclosure [Abstract]
Income Taxes	NOTE 8 – INCOME TAXES Income tax (benefit) was ($ 151 ,000) and ($ 60 ,000) for the three months ended March 31, 2023 and 2022, respectively. Deferred tax assets are deferred tax consequences attributable to deductible temporary differences and carryforwards. After the deferred tax asset has been measured using the applicable enacted tax rate and provisions of the enacted tax law, it is then necessary to assess the need for a valuation allowance. A valuation allowance is needed when, based on the weight of the available evidence, it is more likely than not that some portion of the deferred asset will not be realized. As required by generally accepted accounting principles, available evidence is weighted heavily on cumulative losses, with less weight placed on future projected profitability. The realization of deferred tax assets is dependent on the existence of taxable income of the appropriate character (e.g., ordinary or capital) within the carry-back and carry-forward periods available under tax law, which would consider future reversals of existing taxable temporary differences and available tax planning strategies. As of March 31, 2023, and December 31, 2022 , the deferred tax valuation allowance was $ 934 ,000, reducing our net deferred tax asset to $ 8.1 million and $ 8.3 million at each respective date. The board and management continue to assess the deferred tax assets in light of recent changes in market conditions, forecasted future projected income and available tax planning strategies. As such, there may be additional deferred tax asset impairment in subsequent periods.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE 9 – COMMITMENTS AND CONTINGENCIES In the normal course of business, the Company may be involved in various legal proceedings. In the opinion of management, any liability resulting from such proceedings would not have a material adverse effect on the Company’s financial statements. No material legal proceedings existed at March 31, 2023. In the normal course of business, the Company is party to financial instruments with off-balance-sheet risk to meet the financing needs of its customers. These instruments include commitments to extend credit and commitments to sell loans. These instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized on the balance sheets. The Company’s exposure to credit losses is represented by the contractual, or notional, amount of these commitments. The Company follows the same credit policies in making commitments as it does for on-balance-sheet instruments. As some of the commitments are expected to expire without being drawn upon, and some of the commitments may not be drawn upon to the total extent of the commitment, the notional amount of these commitments does not necessarily represent future cash requirements of the Company. ASU 2016-13 requires that we establish an allowance for credit losses for off-balance sheet credit exposures, including unfunded loan commitments, that meet certain requirements. The allowance for credit losses for off-balance sheet credit exposures is estimated by portfolio segment at each balance sheet date under the CECL model using the same methodologies as portfolio loans, also taking into consideration management’s assumption of the likelihood that funding will occur. The allowance for credit losses for off-balance sheet credit exposures is included in other liabilities on the Company’s Consolidated Balance Sheets. Additional provisions for expected losses occur through a charge to the provision for credit losses. The adoption of the ASU 2016-13 resulted in the establishment of a $ 665,000 allowance for credit losses for unfunded loan commitments, based on $ 41.1 million in outstanding loan commitments that are expected to fund. At March 31, 2023, the allowance for credit losses for unfunded commitments was $ 665,000 and there were $ 36.9 million in outstanding commitments to extend credit were expected to fund. The contractual amounts of off-balance-sheet credit-related financial instruments are summarized below: March 31, 2023 Fixed Rate Variable Rate Total (in thousands) Commitments to extend credit $ 4,191 $ 74,490 $ 78,681 Standby letters of credit — 150 150 Credit enhancement under the FHLB of Chicago Mortgage Partnership Finance Program 904 — 904 Commitments to sell loans 853 — 853 Overdraft protection program commitments 3,845 — 3,845 December 31, 2022 Fixed Rate Variable Rate Total (in thousands) Commitments to extend credit $ 3,391 $ 80,631 $ 84,022 Standby letters of credit — 150 150 Credit enhancement under the FHLB of Chicago Mortgage Partnership Finance Program 894 — 894 Commitments to sell loans 1,292 — 1,292 Overdraft protection program commitments 3,881 — 3,881 NOTE 9 – COMMITMENTS AND CONTINGENCIES (continued) Commitments to extend credit are agreements to lend to a customer at fixed or variable rates, as long as there is no violation of any condition established in the contract. Commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. The amount of collateral obtained upon extension of credit is based on management’s credit evaluation of the customer. Collateral held varies but may include accounts receivable; inventory; property, plant and equipment; real estate; and stocks and bonds. Commitments to sell loans represent commitments obtained by the Company from a secondary market agency to purchase mortgages from the Company at specified interest rates and within specified periods of time. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the performance of a customer to a third party. Generally, all standby letters of credit have expiration dates within one year. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The Company generally holds collateral supporting these commitments. Standby letters of credit are not reflected in the financial statements, since recording the fair value of these guarantees would not have a significant impact on the financial statements. The Company participates in the Federal Home Loan Bank of Chicago Mortgage Partnership Finance Program (the “Program”). In addition to entering into forward commitments to sell mortgage loans to a secondary market agency, the Company enters into firm commitments to deliver loans to the Federal Home Loan Bank of Chicago through the Program. Under the Program, loans are funded by the Federal Home Loan Bank of Chicago, and the Company receives an agency fee reported as a component of gain on sale of loans. The Company had $ 431,000 of commitments to deliver loans through the Program as of March 31, 2023. Once delivered to the Program, the Company provides a contractually agreed-upon credit enhancement and performs servicing of the loans. Under the credit enhancement, the Company is liable for losses on loans delivered through the Program after application of any mortgage insurance and a contractually agreed-upon credit enhancement provided by the Program, subject to an agreed-upon maximum. The Company receives a fee for this credit enhancement. The Company records a liability for expected losses in excess of anticipated credit enhancement fees. As of March 31, 2023, and December 31, 2022 , the Company had no liability outstanding related to the Program. Unfunded commitments under overdraft protection agreements are commitments for possible future extensions of credit to existing customers. These lines of credit may or may not require collateral and may or may not contain a specific maturity date.

Share-based Payment Arrangement [Abstract]
Employee Stock Ownership Plan	NOTE 10 – EMPLOYEE STOCK OWNERSHIP PLAN The Company established a tax qualified Employee Stock Ownership Plan (“ESOP”) for the benefit of its employees, in conjunction with the reorganization. Eligible employees become 20 % vested in their accounts after 1 year of service, 40 % vested after 2 years of service, 60 % vested after 3 years of service, 80 % vested after 4 years of service, and 100 % vested after 5 or more years of service, or earlier, upon death, disability or attainment of normal retirement age. On January 8, 2019, the ESOP purchased 175,528 shares ( 231,047 shares adjusted for the conversion) of the Company’s common stock, which was funded by a loan from Old 1895 Bancorp. Unreleased ESOP shares collateralize the loan payable, and the cost of the shares is recorded as contra-equity account in the stockholders’ equity of the Company. Shares are to be released as debt payments are made by the ESOP to the loan. The ESOP’s sources of repayment of the loan can include dividends, if any, on the unallocated stock held by the ESOP, and discretionary contributions from the Company to the ESOP and earnings thereon. As part of the mutual-to-stock conversion and stock offering completed on July 14, 2021, the ESOP refinanced the aforementioned loan with New 1895 Bancorp, enabling the ESOP to purchase an aggregate of 283,360 additional shares of common stock. The ESOP completed the purchase of all the additional 283,360 shares at an average price of $ 10.90 in the second quarter of 2022. Compensation expense for the ESOP is recorded at an amount equal to the shares allocated by the ESOP multiplied by the average fair market value of the shares during the period. The Company recognizes compensation expense ratably over the year based upon the Company’s estimate of the number of shares expected to be allocated by the ESOP. Unearned compensation applicable to the ESOP is reflected as a reduction of stockholders’ equity in the consolidated balance sheet. The difference between the average fair market value and the cost of the shares allocated by the ESOP is recorded as an adjustment to stockholders’ equity. The Company recognized $ 47,000 and $ 51,000 in compensation expense for the three months ended March 31, 2023 and March 31, 2022, respectively. The following table provides the allocated and unallocated shares of common stock associated with the ESOP.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	NOTE 12 – FAIR VALUE MEASUREMENTS ASC Topic 820, Fair Value Measurements and Disclosures defines fair values, establishes a framework for measuring fair value and expands disclosures about fair value measurements. This accounting standard applies to reported balances that are required or permitted to be measured at fair value under existing accounting pronouncements. The standard also emphasizes that fair value (i.e., the price that would be received in an orderly transaction that is not a forced liquidation or distressed sale at the measurement date), among other things, is based on exit price versus entry price, should include assumptions about risk such as nonperformance risk in liability fair values, and is a market-based measurement, not an entity-specific measurement. When considering the assumptions that market participants would use in pricing an asset or liability, this accounting standard establishes a fair value hierarchy that distinguishes between market participant assumptions based on market data obtained from sources independent of the reporting entity (observable inputs that are classified within Levels 1 and 2 of the hierarchy) and the reporting entity’s own assumptions about market participant assumptions (unobservable inputs classified within Level 3 of the hierarchy). The fair value hierarchy prioritizes inputs used to measure fair value into three broad levels. Level 1 inputs – In general, fair values determined by Level 1 inputs use quoted market prices in active markets for identical assets or liabilities that we have the ability to access. Level 2 inputs – Fair values determined by Level 2 inputs use inputs other than quoted prices included in Level 1 inputs that are observable for the asset or liability, either directly or indirectly. Level 2 inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets where there are few transactions and inputs other than quoted prices that are observable for the asset or liability, such as interest rates and yield curves that are observable at commonly quoted intervals. Level 3 inputs – Level 3 inputs are unobservable inputs for the asset or liability and include situations where there is little, if any, market activity for the asset or liability. In instances where the determination of the fair value measurement is based on inputs from different levels of the fair value hierarchy, the level in the fair value hierarchy within which the entire fair value measurement falls is based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment, and considers factors specific to the asset or liability. 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 collateral dependent loans, may be measured at fair value on a nonrecurring basis. NOTE 12 – FAIR VALUE MEASUREMENTS (continued) Following is a description of the Company’s valuation methodology and significant inputs used for each asset and liability measured at fair value on a recurring or nonrecurring basis. Securities – Marketable equity securities and securities available-for-sale may be classified as Level 1 or Level 2 measurements within the fair value hierarchy. Level 1 securities include equity securities traded on a national exchange. The fair value measurements of Level 1 securities are based on the quoted market price of those securities. Level 2 securities include U.S. Treasury notes, U.S. government and agency securities, obligations of states and political subdivisions, corporate debt securities and mortgage-related securities. The fair value measurements of Level 2 securities are obtained from independent pricing services and are based on recent sales of similar securities and other observable market data. Collateral dependent loans – The Company does not record loans at fair value on a recurring basis. However, individually evaluated loans are reported at the fair value of the underlying collateral, less estimated costs to sell, if repayment is expected solely from the collateral. Independent appraisals are obtained to determine the fair values of underlying collateral, and generally utilize one or more valuation methodologies, which typically include comparable sales and income approaches. Management routinely evaluates the fair value measurements of independent appraisers and adjusts those valuations based on differences noted between actual selling prices of collateral and the most recently appraised value. Such adjustments are usually significant, which results in a Level 3 classification. Rate lock commitments – Rate lock commitments on mortgage loans that are intended to be sold are considered to be derivatives. Accordingly, such commitments, along with any related fees received from potential borrowers, are recorded at fair value in other assets or liabilities, with changes in fair value recorded in the net gain or loss on sale of mortgage loans. Fair value is based on fees currently charged to enter into similar agreements for fixed-rate commitments and also considers the difference between current levels of interest rates and the committed rates. While there are Level 2 and 3 inputs used in the valuation models, the Company has determined that one or more of the inputs significant in the valuation of both of the mortgage banking derivatives fall within Level 3 of the fair value hierarchy. The change in fair value is recorded through an adjustment to the statement of operations, within mortgage banking income. Mortgage servicing rights – The Company utilizes an independent valuation from a third party which uses a discounted cash flow model to estimate the fair value of mortgage servicing rights. The model utilizes prepayment assumptions to project cash flows related to the mortgage servicing rights based upon the current interest rate environment, which is then discounted to estimate an expected fair value of the mortgage servicing rights. The model considers characteristics specific to the underlying mortgage portfolio, such as: contractually specified servicing fees, prepayment assumptions, delinquency rates, late charges and costs to service. Given the significance of the unobservable inputs utilized in the estimation process, mortgage servicing rights are classified as Level 3 within the fair value hierarchy. The Company records the mortgage servicing rights at the lower of amortized cost or fair value. Assets measured at fair value on a recurring basis are summarized below, along with the level of the fair value hierarchy of the inputs utilized to determine such fair value.

Fair value is best determined based on quoted market prices. However, in many instances, there are no quoted market prices for the Company’s various financial instruments. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. Accordingly, the fair value estimates may not be realized in an immediate settlement of the instrument. Consequently, the aggregate fair value amounts presented may not necessarily represent the underlying fair value of the Company. Fair value estimates are made at a specific point in time based on relevant market information and information about the financial instrument. These estimates do not reflect any premium or discount that could result from offering for sale at one time the Company’s entire holdings of a particular instrument. Because no market exists for a significant portion of the Company’s financial instruments, fair value estimates are based on judgments regarding future expected loss experience, current economic conditions, risk characteristics of various financial instruments and other factors. These estimates are subjective in nature and involve uncertainties and matters that could affect the estimates. Fair value estimates are based on existing on- and off-balance-sheet financial instruments without attempting to estimate the value of anticipated future business. Deposits with no stated maturities are defined as having a fair value equivalent to the amount payable on demand. This prohibits adjusting fair value derived from retaining those deposits for an expected future period of time. This component, commonly referred to as a deposit base intangible, is neither considered in the above amounts, nor is it recorded as an intangible asset on the balance sheets. In addition, the tax ramifications related to the realization of unrealized gains and losses can have a significant effect on fair value estimates and have not been considered in the estimates.

Equity and Regulatory Matters	NOTE 13 – EQUITY AND REGULATORY MATTERS PyraMax Bank is subject to various regulatory capital requirements administered by federal and state 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 consolidated 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 the Bank's 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 their components, risk weightings and other factors. The Company is exempt from consolidated capital requirements as those requirements do not apply to certain small bank holding companies with consolidated assets under $ 3 billion. Quantitative measures established by regulation to ensure capital adequacy require the Bank to maintain minimum amounts and ratios (set forth in the table below) of Common Equity Tier 1, Tier 1 and Total capital to risk-weighted assets, and of Tier 1 capital to average assets. The Bank met all applicable capital adequacy requirements as of March 31, 2023 and December 31, 2022. As of March 31, 2023, the Bank was 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 below. There are no conditions or events since March 31, 2023 that management believes have changed the capital category of the Bank.

Earnings (Loss) Per Share	NOTE 14 – EARNINGS (LOSS) PER SHARE Basic earnings (loss) per share is computed by dividing net (loss) income by the weighted average number of common shares outstanding, adjusted for weighted average unallocated ESOP shares, during the applicable period. Diluted earnings per share is computed using the weighted-average number of shares determined for the basic earnings per common share computation plus the dilutive effect of stock compensation using the treasury stock method. Antidilutive options are disregarded in earnings per share calculations. For the three months ended March 31, 2023 , 131,093 average shares were excluded from the computation of diluted EPS because the effect would be antidilutive. For the three months ended March 31, 2022 , 189,715 average shares were excluded from the computation of diluted EPS because the effect would be antidilutive. Earnings (loss) per common share for the three months ended March 31, 2023 and 2022 are presented in the following table. Three months ended March 31, 2023 2022 (In thousands, except per share amounts) Net (loss) $ ( 361 ) $ ( 55 ) Weighted shares outstanding for basic EPS Weighted average shares outstanding 5,986,822 6,275,850 Less: Weighted average unallocated ESOP shares 451,333 401,886 Weighted average shares outstanding for basic EPS 5,535,489 5,873,964 Additional dilutive shares (1) — — Weighted average shares outstanding for dilutive EPS 5,535,489 5,873,964 Basic (loss) per share $ ( 0.07 ) $ ( 0.01 ) Diluted (loss) per share (1) $ ( 0.07 ) $ ( 0.01 ) (1) For the three months ended March 31, 2023 and March 31, 2022, the effect of stock options was anti-dilutive and therefore no dilutive shares are included in the weighted average shares outstanding or diluted loss calculations.

Share-based Payment Arrangement [Abstract]
Stock Based Compensation	NOTE 15 – STOCK BASED COMPENSATION Stock-Based Compensation Plans On March 27, 2020, the Company’s stockholders approved the 1895 Bancorp of Wisconsin, Inc. 2020 Equity Incentive Plan (the “2020 Equity Incentive Plan”). A total of 238,467 stock options and 95,387 restricted shares were approved for award. As of March 31, 2023, no shares of common stock remained available for grant as stock options, restricted stock or restricted stock units under the 2020 Equity Incentive Plan. The stock options granted to employees and non-employee directors under this plan vest in five installments with the first installment vesting on the first anniversary of the date of grant. The exercise price for all stock options granted is equal to the quoted NASDAQ market close price on the date that the awards were granted and expire ten years after the grant date, if not exercised. The restricted stock awards granted to employees and non-employee directors under this plan vest in five installments with the first installment vesting on the first anniversary of the date of grant. On August 26, 2022, the Company’s shareholders approved the 1895 Bancorp of Wisconsin, Inc. 2022 Equity Incentive Plan (the “2022 Equity Incentive Plan”). A total of 354,200 stock options and 141,680 restricted shares were approved for award. As of March 31, 2023, 14,745 shares of common stock remain available for grant as stock options and 11,298 shares remain available for grant as restricted stock or stock units under the 2022 Equity Incentive Plan. The stock options granted to employees and non-employee directors under this plan vest in five installments with the first installment vesting on the first anniversary of the date of grant. The exercise price for all stock options granted is equal to the quoted NASDAQ market close price on the date that the awards were granted and expire ten years after the grant date, if not exercised. The restricted stock awards granted to employees and non-employee directors under this plan vest in five installments with the first installment vesting on the first anniversary of the date of grant. Accounting for Stock-Based Compensation Plan The fair value of stock options granted is estimated on the grant date using a Black-Scholes pricing model. The fair value of restricted shares is equal to the quoted NASDAQ market closing price on the date of grant. The fair value of stock grants is recognized as compensation expense on a straight-line basis over the vesting period of the grants. Compensation expense is included in salaries and employee benefits in the consolidated statements of operations. Assumptions are used in estimating the fair value of stock options granted. The weighted average expected life of the stock options represent the period of time that the options are expected to be outstanding and is based on the historical results from the previous awards. The risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant. The expected volatility is based on the actual volatility of 1895 Bancorp of Wisconsin, Inc. stock for the weighted average life time period prior to issuance date. The following assumptions were used in estimating the fair value of options granted during the three months ended March 31, 2023 and March 31, 2022, respectively: For the Three Months Ended March 31, March 31, Dividend yield 0.00 % N/A (1) Risk-free interest rate 3.59 % N/A (1) Expected volatility 24.64 % N/A (1) Weighted average expected life (years) 6.50 N/A (1) Weighted average per share value of options $ 3.37 N/A (1) (1) There were no stock options granted during the three months ended March 31, 2022.

Significant Accounting Polici_2

Significant Accounting Policies (Policies)	3 Months Ended

Accounting Policies [Abstract]
Credit Losses for Available-for-Sale Debt Securities	Credit Losses for Available-for-Sale Debt Securities For available-for-sale ("AFS") debt securities where fair value is less than amortized cost, the security is considered impaired when amounts are deemed uncollectible or when the Company intends, or more likely than not will be required, to sell the AFS debt security before recovery of the amortized cost basis. On a quarterly basis the Company evaluates the AFS debt securities for impairment. Securities that are in an unrealized loss position are reviewed to determine if a securities credit loss exists based on certain quantitative and qualitative factors. The primary factors considered in evaluating whether an impairment exists include: (a) the extent to which the fair value is less than the amortized cost basis, (b) the financial condition, credit rating and future prospects of the issuer, (c) whether the debtor is current on contractually obligated interest and principal payments, and (d) whether the Company intends to sell the security and whether it is more likely than not that the Company will not be required to sell the security. If a determination is made that an AFS debt security is impaired, the Company will estimate the amount of the unrealized loss that is attributable to credit and all other non-credit related factors. The credit related component will be recognized as a provision for credit losses on securities through an allowance for credit losses. The provision for credit losses on securities will be limited to the difference between the security’s amortized cost basis and fair value. Any future changes may be reversed, limited to the amount previously expensed, in the period they occur. The non-credit related component will be recorded as an adjustment to accumulated other comprehensive income, net of tax.
Allowance for Credit Losses	Allowance for Credit Losses Under the current expected credit loss (“CECL”) model, the allowance for credit losses ("ACL") on financial assets is a valuation allowance estimated at each balance sheet date in accordance with GAAP that is deducted from the financial assets’ amortized cost basis to present the net amount expected to be collected on the financial assets. The CECL model also applies to certain off-balance sheet credit exposures. The Company estimates the allowance for credit losses on loans based on the underlying assets’ amortized cost basis, which is the amount at which the financing receivable is originated or acquired, adjusted for applicable accretion or amortization of premium, discount, net deferred fees or costs, collection of cash, and charge-offs. In the event that collection of principal becomes uncertain, the Company has policies in place to write-off accrued interest receivable by reversing interest income at the time of this determination. Therefore, the Company has made a policy election to exclude accrued interest from the amortized cost basis and therefore excludes it from the measurement of the allowance for credit losses. NOTE 2 – SIGNIFICANT ACCOUNTING POLICIES (continued) Expected credit losses are reflected in the allowance for credit losses through a charge to provision for credit losses. The Company’s estimate of the allowance for credit losses reflects credit losses currently expected over the remaining contractual life of the assets. When the Company deems all or a portion of a financial asset to be uncollectible, the appropriate amount is written off and the allowance for credit losses is reduced by the same amount. The Company applies judgment to determine when a financial asset is deemed uncollectible. When available information confirms that specific financial assets, or portions thereof, are uncollectible, these amounts are charged off against the allowance for credit losses. Subsequent recoveries, if any, are credited to the allowance for credit losses when received. The Company measures the allowance for credit losses of financial assets on a collective portfolio segment basis when the financial assets share similar risk characteristics. The Company has identified the following portfolio segments of financial assets with similar risk characteristics for measuring expected credit losses: commercial real estate, residential real estate – first mortgage, residential real estate – construction, consumer – home equity and lines of credit and other consumer loans. The Company further segments the commercial loan portfolios by risk rating and the residential and consumer loan portfolios by delinquency. The Company utilizes the weighted average maturity (WARM) methodology to measure the ACL. This methodology incorporates both quantitative and qualitative information to assess lifetime expected credit losses at the portfolio segment level. The quantitative component includes the calculation of loss rates that are based on historical lookback periods. The Company calculates a loss rate based on historical loan level loss experience for portfolio segments with similar risk characteristics. The historical loss rate is adjusted for select macroeconomic variables that consider both historical trends as well as forecasted trends. The Company measures expected credit losses of these financial assets by applying loss rates to the amortized cost basis of each asset taking into consideration amortization, prepayment and default assumptions. The Company considers qualitative adjustments to expected credit loss estimates for information not already captured in the loss estimation process. Qualitative factor adjustments may increase or decrease management’s estimate of expected credit losses. Adjustments will not be made for information that has already been considered and included in the quantitative component. Qualitative loss factors are based on management's judgment of company, market, industry or business specific data, changes in loan composition, performance trends, regulatory changes, uncertainty of macroeconomic forecasts, and other asset specific risk characteristics.
Collateral Dependent Financial Assets	Collateral Dependent Financial Assets For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable and where the borrower is experiencing financial difficulty, the allowance for credit losses is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. Fair value is generally calculated based on the value of the underlying collateral less estimated costs to sell.
Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures	Loan Commitments and Allowance for Credit Losses on Off-Balance Sheet Credit Exposures Financial assets include off-balance sheet credit instruments, such as commitments to make loans and commercial letters of credit, issued to meet customer financing needs. The Company’s exposure to loan credit loss in the event of nonperformance by the other party to the financial instrument for off-balance sheet loan commitments is represented by the contractual amount of those instruments. Such financial instruments are recorded when they are funded.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards ASU 2016-13, Financial Instruments – Credit Losses: Measurement of Credit Losses on Financial Instruments (Topic 326) . ASU 2016-13 requires organizations to measure all expected credit losses for financial instruments held at the reporting date based on historical experience, current conditions and reasonable and supportable forecasts. In March 2022, the FASB issued ASU 2022-02, Financial Instruments—Credit Losses (Topic 326): Troubled Debt Restructurings and Vintage Disclosures , which eliminates the accounting guidance for troubled debt restructurings by creditors, while enhancing disclosure requirements for certain loan refinancings and restructurings by creditors when a borrower is experiencing financial difficulty. In addition, ASU 2022-02 requires that an entity disclose current-period gross write-offs by year of origination for financing receivables and net investments in leases within the scope of Subtopic 326-20, Financial Instruments—Credit Losses . The Company adopted ASU 2016-13 and ASU 2022-02 as of January 1, 2023 using the modified retrospective method for all financial assets measured at amortized cost and off-balance sheet credit exposures . The adoption of ASU 2016-13 resulted in an initial increase of $ 412,000 to the allowance for credit losses for loans and the establishment of a $ 665,000 allowance for credit losses for unfunded loan commitments. The allowance for credit losses for unfunded loan commitments is included in other liabilities on the Company's Consolidated Balance Sheets. The after-tax cumulative-effect adjustment of $ 783,000 was recorded in retained earnings as of January 1, 2023.
