Nature of Operations
Nature of Operations	Note 1 - Nature of Operations William Penn Bancorp, Inc. (“William Penn Bancorp”) is a Pennsylvania chartered mid-tier stock holding company and owns 100% of the outstanding common stock of William Penn Bank (the “Bank”), a Pennsylvania chartered stock savings bank. The Bank offers consumer and commercial banking services to individuals, businesses, and nonprofit organizations throughout the Delaware Valley area through twelve full-service branch offices in Bucks County and Philadelphia, Pennsylvania, and Burlington and Camden Counties in New Jersey. William Penn Bancorp is subject to regulation and supervision by the Board of Governors of the Federal Reserve System. The Bank is supervised and regulated by the Federal Deposit Insurance Corporation (“FDIC”) and the Pennsylvania Department of Banking and Securities. On September 16, 2020, the Boards of Directors of William Penn Bancorp, the Bank, and William Penn, MHC (the “MHC”), the parent mutual holding company of the Bank, unanimously adopted a Plan of Conversion and Reorganization, which was subsequently amended and restated on October 6 2020 (the “Plan of Conversion”). Pursuant to the Plan of Conversion, the MHC will sell its majority ownership in William Penn Bank to the public and William Penn Bancorp, which is currently in the mutual holding company structure, will reorganize to the fully public stock holding company form of organization in a transaction commonly referred to as a “second-step” conversion. William Penn Bancorporation (the "Company") was incorporated in July 2020 by William Penn Bancorp to be the Bank's holding company upon completion of the second-step conversion. The Company filed a Registration Statement on Form S-1 (the "Form S-1"), as amended, with the U.S. Securities and Exchange Commission (the "SEC"), which the SEC declared effective on January 15, 2021 and the Company currently anticipates, subject to approval of the members of the MHC and the stockholders of William Penn Bancorp, as well as satisfaction of customary closing conditions, the second-step conversion will be completed in March 2021.

Summary of Significant Accounting Policies
Summary of Significant Accounting Policies	Note 2 - Summary of Significant Accounting Policies Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of the William Penn Bancorp, and its wholly owned subsidiary, the Bank, and the Bank’s wholly owned subsidiaries, WPSLA Investment Corporation (“WPSLA”), Fidelity Asset Recovery Specialists, LLC, and Washington Service Corporation (“WSC”). WPSLA is a Delaware corporation organized in April 2000 to hold investment securities and loans for the Bank. At December 31, 2020, WPSLA held $90.9 million of the Bank’s $112.9 million investment securities portfolio and $53.4 million of the Bank’s $498.4 million loan portfolio. Fidelity Asset Recovery Specialists, LLC is Pennsylvania limited liability company organized in March 2015 that the Bank acquired in connection with its acquisition of Fidelity Savings Association of Bucks County (“Fidelity”) in May 2020. Fidelity Asset Recovery Specialists, LLC, which is currently inactive and in the process of dissolution, was formerly utilized by Fidelity to manage and hold other real estate owned properties in Pennsylvania until disposition. WSC is a Pennsylvania corporation organized in October 2000 that the Bank acquired in connection with its acquisition of Washington Savings Bank (“Washington”) in May 2020. WSC held commercial real estate, including a branch office, located in Philadelphia, Pennsylvania that was owned by Washington and was sold by William Penn Bank in October 2020. WSC is currently inactive and is in the process of dissolution. All significant intercompany accounts and transactions have been eliminated. Management makes significant operating decisions based upon the analysis of the entire Company and financial performance is evaluated on a company-wide basis. Accordingly, the various financial services and products offered are aggregated into one reportable operating segment: community banking as under guidance in the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC” or “codification”) Topic 280 for Segment Reporting. Use of Estimates in the Preparation of Financial Statements These consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. The significant estimates include the allowance for loan losses, goodwill, intangible assets, income taxes, postretirement benefits, and the fair value of investment securities. Actual results could differ from those estimates and assumptions. Presentation of Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing demand deposits, and federal funds sold. Revenue Recognition Management determined that the primary sources of revenue emanating from interest and dividend income on loans and investments, along with noninterest revenue resulting from investment security and loan gains (losses) and earnings on bank owned life insurance, are not within the scope of ASC 606. The main types of noninterest income within the scope of ASC 606 include service charges on deposit accounts. The Bank has contracts with its deposit customers where fees are charged if certain parameters are not met. These agreements can be cancelled at any time by either the Bank or the deposit customer. Revenue from these transactions is recognized on a monthly basis as the Bank has an unconditional right to the fee consideration. The Bank also receives transaction fees related to specific transactions or activities resulting from a customer request or activity that include overdraft fees, online banking fees, interchange fees, ATM fees and other transaction fees, as well as bargain purchase gain. These fees are attributable to specific performance obligations of the Bank where the revenue is recognized at a defined point in time upon the completion of the requested service/transaction. Segment Reporting William Penn Bancorp acts as an independent community financial services provider and offers traditional banking and related financial services to individual, business, and government customers. Through its branch network, the Bank offers a full array of commercial and retail financial services, including the acceptance of time, savings and demand deposits; the making of commercial and mortgage loans; and the providing of other financial services. Management does not separately allocate expenses, including the cost of funding loan demand, between the commercial and retail operations of the Bank. As such, discrete financial information is not available and segment reporting would not be meaningful. Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Subsequent to adopting ASU 2016-02, the FASB issued ASU No. 2019-01, Leases (Topic 842) In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments Effective July 1, 2018, the Company adopted Accounting Standards Update ASU 2014-09, Revenue from contracts with Customers – Topic 606 dividend income on loans and investments along with noninterest revenue resulting from investment security gains, and earnings on bank owned life insurances are not within the scope of ASC 606. As a result, no changes were made during the period related to these sources of revenue. The main types of noninterest income within the scope of the standard are as follows: service charges on deposit accounts—the Company has contracts with its deposit customers where fees are charged if certain parameters are not met. These agreements can be cancelled at any time by either the Company or the deposit customer. Revenue from these transactions is recognized on a monthly basis as the Company has an unconditional right to the fee consideration. The Company also has transaction fees related to specific transactions or activities resulting from a customer request or activity that include overdraft fees, online banking fees, interchange fees, ATM fees and other transaction fees. These fees are attributable to specific performance obligations of the Company where the revenue is recognized at a defined point in time upon the completion of the requested service/transaction. ​

Earnings Per Share
Earnings Per Share	Note 3 - Earnings Per Share The following table presents a calculation of basic and diluted earnings per share for the three and six months ended December 31, 2020 and 2019. Earnings per share is computed by dividing net income available to common shareholders by the weighted average number of shares of common stock outstanding. There are no convertible securities which would affect the numerator in calculating basic and diluted earnings per share; therefore, the net income of $1.4 million and $2.0 million for the three and six months ended December 31, 2020 and $929 thousand and $1.8 million for the three and six months ended December 31, 2019, respectively, was used as the numerator. The following table sets forth the composition of the weighted average common shares (denominator) used in the basic and diluted earnings per share computation. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ Six Months Ended ​ ​ December 31, ​ December 31, ​ 2020 2019 2020 2019 Weighted-average common shares outstanding ​ ​ 4,667,304 ​ ​ 4,158,113 ​ ​ 4,667,304 ​ ​ 4,158,113 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Average treasury stock shares ​ ​ (177,959) ​ ​ (177,959) ​ ​ (177,959) ​ ​ (177,959) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Average unearned ESOP shares ​ ​ — ​ ​ — ​ ​ — ​ ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted-average common shares and common stock equivalents used to calculate basic and diluted earnings per share ​ ​ 4,489,345 ​ ​ 3,980,154 ​ ​ 4,489,345 ​ ​ 3,980,154 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Net Income ​ $ 1,376 ​ $ 929 ​ $ 2,046 ​ $ 1,783 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Basic and diluted earnings per share ​ $ 0.31 ​ $ 0.23 ​ $ 0.46 ​ $ 0.45 ​

As part of this process, management considers its intent to sell each debt security and whether it is more likely than not William Penn Bancorp will be required to sell the security before its anticipated recovery. If either of these conditions is met, OTTI is recognized in earnings equal to the entire difference between the security’s amortized cost basis and its fair value at the most recent balance sheet date. For securities that meet neither of these conditions, management performs analysis to determine whether any of these securities are at risk for OTTI. To determine which individual securities are at risk for OTTI and should be quantitatively evaluated utilizing a detailed analysis, management uses indicators which consider various characteristics of each security including, but not limited to, the following: the credit rating; the duration and level of the unrealized loss; prepayment assumptions; and certain other collateral-related characteristics such as delinquency rates, the security’s performance, and the severity of expected collateral losses. The unrealized loss on securities greater than 12 months is due to current interest rate levels relative to William Penn Bancorp’s cost. Because the unrealized losses are due to current interest rate levels relative to William Penn Bancorp’s cost and not credit quality, and because William Penn Bancorp does not intend to sell the investments and it is not more likely than not that William Penn Bancorp will be required to sell these investments before recovery of its amortized cost, which may be at maturity, William Penn Bancorp does not consider these investments to be other-than temporarily impaired at December 31, 2020 and June 30, 2020. There were 29 investment securities that were temporarily impaired at December 31, 2020. Based on its analysis, management has concluded that the investment securities portfolio has experienced unrealized losses and a decrease in fair value due to interest rate volatility. However, the decline is considered temporary, and William Penn Bancorp does not intend to sell these securities nor is it more likely than not William Penn Bancorp would be required to sell the security before its anticipated recovery, which may be maturity. At December 31, 2020, $4.6 million of investment securities were pledged to secure municipal deposits. At June 30, 2020, $3.7 million of investment securities were pledged to secure municipal deposits.

The $129.7 million of one- to four-family investor loans at December 31, 2020 included $129.3 million of first mortgages and $444 thousand of home equity and HELOCs. At June 30, 2020, the balance of one- to four-family residential real estate loans and home equity and HELOCs included $114.1 million of loans of one- to four-family residences investor loans, representing approximately 22.0% of total loans. The $114.1 million of one- to four-family investor loans at June 30, 2020 included $113.6 million of first mortgages and $507 thousand of home equity and HELOCs. During the three months ended June 30, 2020, the Bank provided $2.4 million in Paycheck Protection Program (PPP) loans for 56 new and existing customers, which are guaranteed by the Small Business Administration and mature in two years. As of December 31, 2020 and June 30, 2020, the $2.4 million of PPP loans are included in commercial loans in the above table. During the three months ended June 30, 2020, the Bank also modified approximately $49.8 million of existing loans in accordance with the provisions of the 2020 Coronavirus Aid, Relief, and Economic Security (“CARES”) Act to provide its customers with monetary relief. Generally, these modifications included the deferral of principal and interest payments for a period of three months, although interest income continued to accrue. The three-month deferral period has ended on a portion of the loans on deferral and the Bank received payments of principal and interest on a portion of the loans on deferral and, as of December 31, 2020, $3.0 million of loans remain on deferral under the CARES Act. Mortgage loans serviced for others are not included in the accompanying Consolidated Statements of Financial Condition. The total amount of loans serviced for the benefit of others was approximately $23.5 million and $26.6 million at December 31, 2020 and June 30, 2020, respectively. Custodial escrow balances maintained in connection with the foregoing loan servicing are included in advances from borrowers for taxes and insurance. Allowance for Loan Losses. The provision for loan losses was determined by management to be an amount necessary to maintain a balance of allowance for loan losses at a level that considers all known and current losses in the loan portfolio as well as potential losses due to unknown factors such as the economic environment. Changes in the provision were based on management’s analysis of various factors such as: estimated fair value of underlying collateral, recent loss experience in particular segments of the portfolio, levels and trends in delinquent loans, and changes in general economic and business conditions. William Penn Bancorp considers the allowance for loan losses of $3.6 million and $3.5 million adequate to cover loan losses inherent in the loan portfolio at December 31, 2020 and June 30, 2020, respectively. The following table presents by portfolio segment, the changes in the allowance for loan losses for the periods ended: Three Months Ended ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​

each portfolio of loans were primarily due to fluctuations in the outstanding balance of each portfolio of loans collectively evaluated for impairment. The overall increase in the allowance during the six months ended December 31, 2020 can be primarily attributed to an increase in non-accrual and delinquent loans and the corresponding qualitative adjustment. During the year ended June 30, 2020, the changes in the provision for loan losses related to one- to four-family residential real estate, residential real estate construction loans and commercial real estate land loans were primarily due to uncertainties with the risk profile of these portfolios in the current economic environment as impacted by the COVID-19 pandemic. The increase in reserves due to the COVID-19 pandemic was limited by William Penn Bancorp making enhancements to its credit management function by adding new experienced team members and implementing more robust internal credit measurement and monitoring processes. Credit Quality Information The following tables represent credit exposures by internally assigned grades as of December 31, 2020 and June 30, 2020. The grading analysis estimates the capability of the borrower to repay the contractual obligations of the loan agreements as scheduled or at all. William Penn Bancorp’s internal credit risk grading system is based on experiences with similarly graded loans. William Penn Bancorp’s internally assigned grades are as follows: Pass – loans which are protected by the current net worth and paying capacity of the obligor or by the value of the underlying collateral. Special Mention – loans where a potential weakness or risk exists, which could cause a more serious problem if not corrected. Substandard – loans that have a well-defined weakness based on objective evidence and are characterized by the distinct possibility that the Bank will sustain some loss if the deficiencies are not corrected. Doubtful – loans classified as doubtful have all the weaknesses inherent in a substandard asset. In addition, these weaknesses make collection or liquidation in full highly questionable and improbable, based on existing circumstances.

Impaired Loans Management considers commercial loans and commercial real estate loans which are 90 days or more past due to be impaired. Larger commercial loans and commercial real estate loans which are 60 days or more past due are selected for impairment testing in accordance with GAAP. Factors considered by management in determining impairment include payment status and collateral value. The amount of impairment for these types of loans is determined by the difference between the present value of the expected cash flows related to the loan, using the original interest rate, and its recorded value, or as a practical expedient in the case of collateralized loans, the difference between the fair value of the collateral and the recorded amount of the loans. These loans are analyzed to determine if it is probable that all amounts will not be collected according to the contractual terms of the loan agreement. If management determines that the value of the impaired loan is less than the recorded investment in the loan (net of previous charge-offs, deferred loan fees or costs and unamortized premium or discount), impairment is recognized through an allowance estimate or a charge-off to the allowance for loan losses. The following tables include the recorded investment and unpaid principal balances for impaired loans with the associated allowance amount, if applicable, at December 31, 2020 and June 30, 2020. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 ​ ​ ​ ​ ​ Unpaid ​ ​ ​ ​ ​ ​ Recorded ​ Principal ​ Related ​ (Dollars in thousands) Investment Balance Allowance With no related allowance recorded: ​ ​ ​ 1-4 Family residential real Estate ​ $ 2,031 ​ $ 2,031 ​ $ — ​ Home equity and HELOCs ​ 671 ​ 677 ​ — ​ Construction Residential ​ — ​ — ​ — ​ Multi-family ​ 183 ​ 183 ​ — ​ Commercial non-residential ​ 1,066 ​ 1,101 ​ — ​ Construction and land ​ — ​ — ​ — ​ Commecial ​ — ​ — ​ — ​ Consumer ​ — ​ — ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ With an allowance recorded: ​ ​ ​ ​ 1-4 Family ​ $ — ​ $ — ​ $ — ​ Home equity and HELOCs ​ — ​ — ​ — ​ Construction Residential ​ — ​ — ​ — ​ Multi-family ​ — ​ — ​ — ​ Commercial non-residential ​ — ​ — ​ — ​ Construction and land ​ — ​ — ​ — ​ Commecial ​ — ​ — ​ — ​ Consumer ​ — ​ — ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total: ​ ​ ​ ​ 1-4 Family ​ $ 2,031 ​ $ 2,031 ​ $ — ​ Home equity and HELOCs ​ 671 ​ 677 ​ — ​ Construction Residential ​ — ​ — ​ — ​ Multi-family ​ 183 ​ 183 ​ — ​ Commercial non-residential ​ 1,066 ​ 1,101 ​ — ​ Construction and land ​ — ​ — ​ — ​ Commecial ​ — ​ — ​ — ​ Consumer ​ — ​ — ​ — ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ The impaired loans table above includes accruing troubled debt restructuings (“TDRs”) in the amount of $1.3 million that are performing in accordance with their modified terms.

Interest income that would have been recorded for the three and six months ended December 31, 2020, had impaired loans been current according to their original terms, amounted to $47 thousand and $95 thousand, respectively. Interest income that would have been recorded for the three and six months ended December 31, 2019, had impaired loans been current according to their original terms, amounted to $43 thousand and $86 thousand, respectively. Troubled Debt Restructurings The Bank determines whether a restructuring of debt constitutes a TDR in accordance with guidance under FASB ASC Topic 310 Receivables ● A review of the borrower’s current financial condition in which the borrower must demonstrate sufficient cash flow to support the repayment of all principal and interest including any amounts previously charged-off; ● An updated appraisal or home valuation which must demonstrate sufficient collateral value to support the debt; and ● Sustained performance based on the restructured terms for at least six consecutive months. During the three months ended June 30, 2020, the Bank began providing customer relief programs, such as payment deferrals or interest only payments on loans. William Penn Bancorp does not consider a modification to be a TDR if it occurred as a result of the loan forbearance program under the CARES Act. The CARES Act provides that a loan term modification does not automatically result in TDR status if the modification is made on a good-faith basis in response to COVID-19 to borrowers who were classified as current and not more than 30 days past due as of December 31, 2019, and executed between March 1, 2020 and the earlier of (a) 60 days after the date of termination of the COVID-19 pandemic national emergency, or (b) December 31, 2020. During the three months ended June 30, 2020, the Bank modified approximately $49.8 million of loans to provide its customers this monetary relief. Generally, these modifications included the deferral of principal and interest payments for a period of three months, although interest income continued to accrue. The three-month deferral period has ended on a portion of the loans on deferral and the Bank received payments of principal and interest on a portion of the loans on deferral and, as of December 31, 2020, $3.0 million of loans remain on deferral under the CARES Act. During the six months ended December 31, 2020 and the year ended June 30, 2020, there were no loans modified that were identified as a TDR. William Penn Bancorp did not experience any re-defaulted TDRs subsequent to the loan being modified during the six months ended December 31, 2020 and the year ended June 30, 2020.

During the year ended June 30, 2020, management included considerations of the current economic environment caused by COVID-19 in its qualitative assessment of goodwill impairment and determined that a quantitative assessment of goodwill was warranted. Management engaged a third-party valuation specialist to perform a quantitative assessment of goodwill impairment and it was determined that it is not more likely than not that the carrying value of goodwill is impaired. No goodwill impairment existed at June 30, 2020. During the six months ended December 31, 2020, management considered the current economic environment caused by the COVID-19 pandemic in its evaluation, and determined based on the totality of its qualitative assessment that it is not more likely than not that the carrying value of goodwill is impaired.

Commitments and Contingencies.
Commitments and Contingencies	Note 11 – Commitments and Contingencies William Penn Bancorp is a party to financial instruments with off-balance sheet risk in the normal course of business to meet the financing needs of its customers. These financial instruments include commitments to extend credit. Those instruments involve, to varying degrees, elements of credit risk in excess of the amount recognized in William Penn Bancorp’s consolidated statements of financial condition. A summary of William Penn Bancorp's loan commitments is as follows as of December 31, 2020 and June 30, 2020: ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, June 30, (Dollars in thousands) ​ 2020 ​ 2020 Commitments to extend credit ​ $ 12,616 ​ $ 18,602 Unfunded commitments under lines of credit ​ 43,850 ​ 52,432 Standby letters of credit ​ 1,000 ​ — ​ Commitments to extend credit are agreements to lend to a customer if there is no violation of any condition established in the contract. Since many of the commitments are expected to expire without being drawn upon, the total commitment amounts do not necessarily represent future cash requirements. Commitments generally have 90-day fixed expiration dates or other termination clauses and may require payment of a fee. William Penn Bancorp evaluates each customer’s credit worthiness on a case-by-case basis. The amount of collateral obtained, if deemed necessary by William Penn Bancorp upon extension of credit, is based on management’s credit evaluation. Collateral held varies, but primarily includes residential and commercial real estate. Periodically, there have been other various claims and lawsuits against the Bank, such as claims to enforce liens, condemnation proceedings on properties in which it holds security interests, claims involving the making and servicing of real property loans and other issues incident to its business. The Bank is not a party to any pending legal proceedings that it believes would have a material adverse effect on its financial condition, results of operations or cash flows.

Regulatory Capital Requirements

Regulatory Capital Requirements
Regulatory Capital Requirements	Note 12 - Regulatory Capital Requirements The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet the 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 Bank’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 the Bank’s assets, liabilities, and certain off-balance sheet items as calculated under regulatory accounting practices. The Bank’s 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 amounts and ratios (described below) of tangible and core capital to total adjusted assets and of total capital to risk-weighted assets. Management believes, as of December 31, 2020 and June 30, 2020, that the Bank meets all capital adequacy requirements to which it is subject. As of December 31, 2020 and June 30, 2020, the most recent notification from the regulators categorized the Bank as “well capitalized” under the regulatory framework for prompt corrective action. To be categorized as well capitalized, the Bank must maintain minimum amounts and ratios of Tier I leverage capital to average assets and of common equity Tier I capital, Tier I capital, and total capital to risk-weighted assets, all as defined in the regulation. The Economic Growth, Regulatory Relief, and Consumer Protection Act enacted in May 2018 required the federal banking agencies, including the Federal Deposit Insurance Corporation, to establish for banks with assets of less than $10 billion of assets a community bank leverage ratio (the ratio of a bank’s tangible equity capital to average total consolidated assets) of 8 to 10%. A qualifying community bank with capital meeting the specified requirements (including off balance sheet exposures of 25% or less of total assets and trading assets and liabilities of 5% or less of total assets) and electing to follow the alternative framework is considered to meet all applicable regulatory capital requirements including the risk-based requirements. The community bank leverage ratio was established at 9% Tier 1 capital to total average assets, effective January 1, 2020. A qualifying bank may opt in and out of the community bank leverage ratio framework on its quarterly call report. A bank that ceases to meet any qualifying criteria is provided with a two-quarter grace period to comply with the community bank leverage ratio requirements or the general capital regulations by the federal regulators. In addition, Section 4012 of the CARES Act required that the community bank leverage ratio be temporarily lowered to 8%. The federal regulators issued a rule making the lower ratio effective April 23, 2020. The rules also established a two-quarter grace period for a qualifying community bank whose leverage ratio falls below the 8% community bank leverage ratio requirement so long as the bank maintains a leverage ratio of 7% or greater. Another rule was issued providing for the transition back to the 9% community bank leverage ratio, increasing the ratio to 8.5% for calendar year 2021 and to 9% thereafter. During the fiscal year ended June 30, 2020, the Bank elected the community bank leverage ratio alternative reporting framework. A “small holding company,” as defined under Federal Reserve Board regulations as a bank holding company or savings and loan holding company with less than $3 billion of consolidated assets, such as William Penn Bancorp, is generally not subject to the regulatory capital requirements applicable to the Bank and outlined above, unless otherwise directed by the Federal Reserve Board. The leverage ratios of the Bank at December 31, 2020 and June 30, 2020 are as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To be Well Capitalized Under ​ ​ ​ ​ ​ ​ ​ ​ For Capital Adequacy ​ Prompt Corrective Action ​ As of December 31, 2020 ​ Actual ​ Purposes ​ Provisions ​ (Dollars in thousands except for ratios) Amount ​ Ratio ​ Amount ​ Ratio ​ Amount ​ Ratio William Penn Bank: ​ ​ Tier 1 leverage ​ $ 88,407 ​ 11.97 % > $ 29,536 ​ > 4.00 % > $ 36,921 ​ > 5.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ To be Well Capitalized Under ​ ​ ​ ​ ​ ​ ​ ​ For Capital Adequacy ​ Prompt Corrective Action ​ As of June 30, 2020 ​ Actual ​ Purposes ​ Provisions ​ (Dollars in thousands except for ratios) ​ Amount ​ Ratio ​ Amount ​ Ratio ​ Amount ​ Ratio William Penn Bank: ​ Tier 1 leverage ​ $ 86,822 ​ 13.67 % > $ 25,397 ​ > 4.00 % > $ 31,746 ​ > 5.00 % ​

Fair Value of Financial Instruments
Fair Value of Financial Instruments	Note 13 – Fair Value of Financial Instruments William Penn Bancorp follows authoritative guidance under FASB ASC Topic 820 for Fair Value Measurements and Disclosures which defines fair value, establishes a framework for measuring fair value, and expands disclosures about fair value measurements. The definition of fair value under ASC 820 is the exchange price. The guidance clarifies that the exchange price is the price in an orderly transaction between market participants to sell the asset or transfer the liability in the market in which the reporting entity would transact for the asset or liability. The definition focuses on the price that would be received to sell the asset or paid to transfer the liability (an exit price), not the price that would be paid to acquire the asset or received to assume the liability (an entry price). The guidance emphasizes that fair value is a market-based measurement, not an entity-specific measurement. Fair value is based on quoted market prices, when available. If listed prices or quotes are not available, fair value is based on fair value models that use market participant or independently sourced market data which include: discount rate, interest rate yield curves, credit risk, default rates and expected cash flow assumptions. In addition, valuation adjustments may be made in the determination of fair value. These fair value adjustments may include amounts to reflect counter party credit quality, creditworthiness, liquidity, and other unobservable inputs that are applied consistently over time. These adjustments are estimated and, therefore, subject to significant management judgment, and at times, may be necessary to mitigate the possibility of error or revision in the model-based estimate of the fair value provided by the model. The methods described above may produce fair value calculations that may not be indicative of the net realizable value. While William Penn Bancorp believes its valuation methods are consistent with other financial institutions, the use of different methods or assumptions to determine fair values could result in different estimates of fair value. FASB ASC Topic 820 for Fair Value Measurements and Disclosures describes three levels of inputs that may be used to measure fair value: Level 1: Quoted prices are available in active markets for identical assets or liabilities as of the reported date. Level 2: Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the reported date. The nature of these assets and liabilities include items for which quoted prices are available but traded less frequently, and items that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 3: Assets and liabilities that have little to no pricing observability as of the reported date. These items do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. The following table presents the assets required to be measured and reported on a recurring basis on William Penn Bancorp’s Consolidated Statements of Financial Condition at their fair value as of December 31, 2020 and June 30, 2020, by level within the fair value hierarchy. Financial assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ December 31, 2020 (Dollars in thousands) Level I ​ Level II ​ Level III ​ Total Assets: ​ ​ ​ ​ Investments available-for-sale: ​ ​ ​ ​ Mortgage-backed securities ​ $ — ​ $ 55,505 ​ $ — ​ $ 55,505 U.S. agency collateralized mortgage obligations ​ — ​ 1,983 ​ — ​ 1,983 U.S. government agency securities ​ — ​ 10,917 ​ — ​ 10,917 Municipal bonds ​ — ​ 22,578 ​ — ​ 22,578 Corporate bonds ​ — ​ 21,926 ​ — ​ 21,926 Total Assets ​ $ — ​ $ 112,909 ​ $ — ​ $ 112,909 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2020 (Dollars in thousands) Level I ​ Level II ​ Level III ​ Total Assets: ​ ​ ​ ​ Investments available-for-sale: ​ ​ ​ ​ Mortgage-backed securities ​ $ — ​ $ 51,738 ​ $ — ​ $ 51,738 U.S. agency collateralized mortgage obligations ​ — ​ 3,215 ​ — ​ 3,215 U.S. government agency securities ​ — ​ 6,155 ​ — ​ 6,155 U.S. treasury securities ​ — ​ 1,000 ​ — ​ 1,000 Municipal bonds ​ — ​ 10,508 ​ — ​ 10,508 Corporate bonds ​ — ​ 17,382 ​ — ​ 17,382 Total Assets ​ $ — ​ $ 89,998 ​ $ — ​ $ 89,998 ​ Assets and Liabilities Measured on a Non-Recurring Basis Certain assets and liabilities may be required to be measured at fair value on a nonrecurring basis in periods subsequent to their initial recognition. Generally, nonrecurring valuation is the result of the application of other accounting pronouncements which require assets and liabilities to be assessed for impairment or recorded at the lower of cost or fair value. Impaired loans are generally measured for impairment using the fair value of the collateral supporting the loan. Evaluating impaired loan collateral is based on Level 3 inputs utilizing outside appraisals adjusted by management for sales costs and other assumptions regarding market conditions to arrive at fair value. As of December 31, 2020 and June 30, 2020, William Penn Bancorp charged-off the collateral deficiency on impaired loans. As a result, there were no specific reserves on impaired loans as of December 31, 2020 and June 30, 2020. Other real estate owned (OREO) is measured at fair value, based on appraisals less cost to sell at the date of foreclosure. Valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value, less cost to sell. Income and expenses from operations and changes in valuation allowance are included in the net expenses from OREO. As of December 31, 2020, there were no assets required to be measured and reported at fair value on a non-recurring basis. As of June 30, 2020, assets required to be measured and reported at fair value on a non-recurring basis are summarized as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ June 30, 2020 (Dollars in thousands) ​ Level I ​ Level II ​ Level III ​ Total Assets: ​ ​ ​ ​ Impaired loans $ — $ — $ 190 $ 190 Other real estate owned ​ — ​ — ​ 100 ​ 100 ​ ​ $ — ​ $ — ​ $ 290 ​ $ 290 ​ Quantitative information regarding assets measured at fair value on a non-recurring basis as of June 30, 2020 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Quantative Information about Level 3 Fair Value Measurements ​ ​ Fair Value ​ Valuation ​ Unobservable ​ ​ (Dollars in thousands) Estimate Techniques Input Range June 30, 2020 ​ ​ Impaired loans ​ $ 190 Appraisal of collateral (1) Appraisal adjustments (2) 0-28 % Foreclosed real estate owned ​ $ 100 Appraisal of collateral (1)(3) Liquidation expenses (2) 0 % (1) F air value is generally determined through independent appraisals of the underlying collateral, which generally include various Level 3 inputs which are not identifiable, less any associated allowance. (2) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range and weighted average of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal. (3) Includes qualitative adjustments by management and estimated liquidation expenses. Management uses its best judgment in estimating the fair value of William Penn Bancorp's financial instruments; however, there are inherent weaknesses in any estimation technique. Therefore, for substantially all financial instruments, the fair value estimates herein are not necessarily indicative of the amounts William Penn Bancorp could have realized in sales transaction on the dates indicated. The estimated fair value amounts have been measured as of their respective year-ends and have not been reevaluated or updated for purposes of these financial statements subsequent to those respective dates. As such, the estimated fair values of these financial instruments subsequent to the respective reporting dates may be different than the amounts reported at each year-end. The following information should not be interpreted as an estimate of the fair value of the entire Company since a fair value calculation is only provided for a limited portion of William Penn Bancorp's assets and liabilities. Due to a wide range of valuation techniques and the degree of subjectivity used in making the estimates, comparisons between William Penn Bancorp's disclosures and those of other companies may not be meaningful. In accordance with FASB ASC Topic 825 for Financial Instruments, Disclosures about Fair Value of Financial Instruments The following tables set forth the carrying value of financial assets and liabilities and the fair value for certain financial instruments that are not required to be measured or reported at fair value on the Consolidated Statements of Financial Condition for the periods indicated. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at December 31, 2020 ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices ​ Significant ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ in Active Markets ​ Other Observable ​ Unobservable ​ ​ Carrying ​ Fair ​ for Identical Assets ​ Inputs ​ Inputs (Dollars in thousands) ​ Amount Value (Level 1) (Level 2) (Level 3) Financial assets: ​ ​ ​ ​ ​ Loans receivable, net ​ $ 494,805 ​ $ 517,970 ​ $ — ​ $ — ​ $ 517,970 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Certificates of deposit ​ 194,148 ​ 196,632 ​ — ​ — ​ 196,632 Advances from Federal Home Loan Bank ​ 41,000 ​ 42,269 ​ — ​ — ​ 42,269 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Fair Value Measurements at June 30, 2020 ​ ​ ​ ​ ​ ​ ​ ​ Quoted Prices ​ Significant ​ Significant ​ ​ ​ ​ ​ ​ ​ ​ in Active Markets ​ Other Observable ​ Unobservable ​ ​ Carrying ​ Fair ​ for Identical Assets ​ Inputs ​ Inputs (Dollars in thousands) Amount Value (Level 1) (Level 2) (Level 3) Financial assets: ​ ​ ​ ​ ​ Loans receivable, net ​ $ 508,605 ​ $ 541,779 ​ $ — ​ $ — ​ $ 541,779 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Financial liabilities: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Certificates of deposit ​ 194,480 ​ 198,268 ​ — ​ — ​ 198,268 Advances from Federal Home Loan Bank ​ 64,892 ​ 67,520 ​ — ​ — ​ 67,520 ​ For cash and due from banks, interest bearing time deposits, regulatory stock, bank-owned life insurance, accrued interest receivable, core deposits, advances from borrowers for taxes and insurance, and accrued interest payable, the carrying amount approximates the fair value and is considered a Level 1 measurement.

Summary of Significant Accounting Policies
Principles of Consolidation and Basis of Presentation	Principles of Consolidation and Basis of Presentation The consolidated financial statements include the accounts of the William Penn Bancorp, and its wholly owned subsidiary, the Bank, and the Bank’s wholly owned subsidiaries, WPSLA Investment Corporation (“WPSLA”), Fidelity Asset Recovery Specialists, LLC, and Washington Service Corporation (“WSC”). WPSLA is a Delaware corporation organized in April 2000 to hold investment securities and loans for the Bank. At December 31, 2020, WPSLA held $90.9 million of the Bank’s $112.9 million investment securities portfolio and $53.4 million of the Bank’s $498.4 million loan portfolio. Fidelity Asset Recovery Specialists, LLC is Pennsylvania limited liability company organized in March 2015 that the Bank acquired in connection with its acquisition of Fidelity Savings Association of Bucks County (“Fidelity”) in May 2020. Fidelity Asset Recovery Specialists, LLC, which is currently inactive and in the process of dissolution, was formerly utilized by Fidelity to manage and hold other real estate owned properties in Pennsylvania until disposition. WSC is a Pennsylvania corporation organized in October 2000 that the Bank acquired in connection with its acquisition of Washington Savings Bank (“Washington”) in May 2020. WSC held commercial real estate, including a branch office, located in Philadelphia, Pennsylvania that was owned by Washington and was sold by William Penn Bank in October 2020. WSC is currently inactive and is in the process of dissolution. All significant intercompany accounts and transactions have been eliminated. Management makes significant operating decisions based upon the analysis of the entire Company and financial performance is evaluated on a company-wide basis. Accordingly, the various financial services and products offered are aggregated into one reportable operating segment: community banking as under guidance in the Financial Accounting Standards Board (the “FASB”) Accounting Standards Codification (“ASC” or “codification”) Topic 280 for Segment Reporting.
Use of Estimates in the Preparation of Financial Statements	Use of Estimates in the Preparation of Financial Statements These consolidated financial statements are prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). The preparation of the consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of income and expenses during the reporting period. The significant estimates include the allowance for loan losses, goodwill, intangible assets, income taxes, postretirement benefits, and the fair value of investment securities. Actual results could differ from those estimates and assumptions.
Presentation of Cash Flows	Presentation of Cash Flows For purposes of reporting cash flows, cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing demand deposits, and federal funds sold.
Revenue Recognition	Revenue Recognition Management determined that the primary sources of revenue emanating from interest and dividend income on loans and investments, along with noninterest revenue resulting from investment security and loan gains (losses) and earnings on bank owned life insurance, are not within the scope of ASC 606. The main types of noninterest income within the scope of ASC 606 include service charges on deposit accounts. The Bank has contracts with its deposit customers where fees are charged if certain parameters are not met. These agreements can be cancelled at any time by either the Bank or the deposit customer. Revenue from these transactions is recognized on a monthly basis as the Bank has an unconditional right to the fee consideration. The Bank also receives transaction fees related to specific transactions or activities resulting from a customer request or activity that include overdraft fees, online banking fees, interchange fees, ATM fees and other transaction fees, as well as bargain purchase gain. These fees are attributable to specific performance obligations of the Bank where the revenue is recognized at a defined point in time upon the completion of the requested service/transaction.
Segment Reporting	Segment Reporting William Penn Bancorp acts as an independent community financial services provider and offers traditional banking and related financial services to individual, business, and government customers. Through its branch network, the Bank offers a full array of commercial and retail financial services, including the acceptance of time, savings and demand deposits; the making of commercial and mortgage loans; and the providing of other financial services. Management does not separately allocate expenses, including the cost of funding loan demand, between the commercial and retail operations of the Bank. As such, discrete financial information is not available and segment reporting would not be meaningful.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842) Subsequent to adopting ASU 2016-02, the FASB issued ASU No. 2019-01, Leases (Topic 842) In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments Effective July 1, 2018, the Company adopted Accounting Standards Update ASU 2014-09, Revenue from contracts with Customers – Topic 606 dividend income on loans and investments along with noninterest revenue resulting from investment security gains, and earnings on bank owned life insurances are not within the scope of ASC 606. As a result, no changes were made during the period related to these sources of revenue. The main types of noninterest income within the scope of the standard are as follows: service charges on deposit accounts—the Company has contracts with its deposit customers where fees are charged if certain parameters are not met. These agreements can be cancelled at any time by either the Company or the deposit customer. Revenue from these transactions is recognized on a monthly basis as the Company has an unconditional right to the fee consideration. The Company also has transaction fees related to specific transactions or activities resulting from a customer request or activity that include overdraft fees, online banking fees, interchange fees, ATM fees and other transaction fees. These fees are attributable to specific performance obligations of the Company where the revenue is recognized at a defined point in time upon the completion of the requested service/transaction.
