Accounting Policies [Abstract]
Summary of significant accounting policies	Note 1. Summary of significant accounting policies Basis of Presentation The consolidated financial statements include the accounts of Greene County Bancorp, Inc. (the “Company”) and its subsidiaries, the Bank of Greene County (the “Bank”), and the Bank’s subsidiaries Greene County Commercial Bank (the “Commercial Bank”) and Greene Property Holdings, Ltd. All material inter-company accounts and transactions have been eliminated in consolidation. The accompanying consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”). These consolidated financial statements consider events that occurred through the date the consolidated financial statements were issued. The consolidated financial statements include the accounts of certain Variable Interest Entities (“VIE(s)”). In accordance with the applicable accounting guidance for consolidations, the Company consolidates a VIE if it has (i) a variable interest in the entity; (ii) the power to direct activities of the VIE that most significantly affect the entity’s economic performance; and (iii) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE (i.e., we are considered to be the primary beneficiary). The Company uses the equity method to account for unconsolidated investments in VIEs if it has significant influence over the entity’s operating and financing decision. Unconsolidated investments in VIEs in which the Company does not have significant influence, are carried at a cost measurement alternative. See Note 14, Variable Interest Entities for information on our involvement with VIEs. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and disclosures provided, and actual results could differ. Nature of Operations The Company’s primary business is the ownership and operation of its subsidiaries. At June 30, 2025, the Company operated 18 full-service banking offices, lending centers, an operations center, customer call center, administration center, and a wealth management center located in its market area consisting of the Hudson Valley and Capital District Regions of New York State. The Bank is primarily engaged in the business of attracting deposits from the general public in the Bank’s market area, and investing such deposits, together with other sources of funds, in loans and investment securities. The Commercial Bank’s primary business is to attract deposits from and provide banking services to local municipalities. Greene Property Holdings, Ltd. was formed as a New York corporation that has elected under the Internal Revenue Code to be a real estate investment trust. Currently, certain mortgages and loan notes held by the Bank are transferred and beneficially owned by Greene Property Holdings, Ltd. The Bank continues to service these loans. Charter The Company and its parent mutual holding company, Greene County Bancorp, MHC (the “MHC”) are federally chartered and regulated and examined by the Federal Reserve Board. The Bank, the subsidiary of the Company, is also federally chartered and is regulated and examined by the Office of the Comptroller of the Currency (the “OCC”). The Commercial Bank is a New York State-chartered financial institution, regulated and examined by the New York State Department of Financial Services. Greene Property Holdings, Ltd. is a New York corporation. As a federal savings association, the Bank must satisfy the qualified thrift lender, or “QTL”, requirement by meeting one of two tests: the Home Owners’ Loan Act (“HOLA”) QTL test or the Internal Revenue Service (IRS) Domestic Building and Loan Association (DBLA) test. The federal savings association may use either test to qualify and may switch from one test to the other. Under the HOLA QTL test, the Bank must maintain at least 65.0% of its “portfolio assets” in “qualified thrift investments” in at least nine of the most recent 12-month period. “Portfolio assets” generally means total assets of a savings institution, less the sum of specified liquid assets up to 20.0% of total assets, goodwill and other intangible assets, and the value of property used in the conduct of the savings association’s business. “Qualified thrift investments” include various types of loans made for residential and housing purposes, investments related to such purposes, including certain mortgage-backed and related securities, and loans for personal, family, household and certain other purposes up to a limit of 20.0% of portfolio assets. “Qualified thrift investments” also include 100.0% of an institution’s credit card loans, education loans and small business loans. Under the IRS DBLA test, the Bank must meet the business operations test and the 60.0% of assets test. The business operations test requires that the federal savings association’s business consists primarily of acquiring the savings of the public (75.0% of its deposits, withdrawable shares, and other obligations must be held by the general public) and investing in loans (more than 75.0% of its gross income consists of interest on loans and government obligations and various other specified types of operating income that federal savings associations ordinarily earn). For the 60.0% of assets test, the Bank must maintain at least 60.0% of its total in “qualified investments” as of the close of the taxable year or, at the option of the taxpayer, may be computed on the basis of the average assets outstanding during the taxable year. A savings association that fails the qualified thrift lender test must either convert to a bank charter or operate under specified restrictions. During the years ended June 30, 2025 and 2024, the Bank elected to utilize the IRS DBLA test and satisfied the requirements of this test. Segment Reporting In accordance with ASU 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures, the Company operates as a single operating segment, banking, providing financial services to retail, municipal and commercial customers in its market area, consisting of the Hudson Valley and Capital District Regions of New York State. The Company derives the majority of its revenue from banking operations within the local market. The Company’s Chief Executive Officer (“CEO”) is designated as the Company’s Chief Operating Decision Maker (“CODM”). The CODM evaluates financial performance and allocates resources by reviewing the consolidated financial statements of the Company, analyzing revenue, expenses, capital levels and budget to actual variances. Cash and Cash Equivalents Cash and cash equivalents include cash on hand, amounts due from banks, interest-bearing deposits at other financial institutions, and overnight federal funds sold. Securities The Company has classified its investments in debt securities as either available-for-sale or held-to-maturity and equity securities. Securities available-for-sale are reported at fair value, with net unrealized gains and losses reflected in the accumulated other comprehensive loss component of shareholders’ equity, net of applicable income taxes. Securities held-to-maturity are those debt securities which management has the intent and the ability to hold to maturity and are reported at amortized cost. Equity securities are recorded at fair value, with net unrealized gains and losses recognized in income. The Company does not have trading securities in its portfolio. Realized gains or losses on security transactions are reported in earnings and computed using the specific identification cost basis. Fair values of securities are based on quoted market prices, where available. Valuation of securities is further described in Note 18, Fair Value Measurements and Fair Value of Financial Instruments, of this Annual Report. Amortization of bond premiums and accretion of bond discounts are amortized over the expected life of the securities using the interest method. Dividend and interest income are recognized when collected. Allowance for Credit Losses on Securities Held-to-Maturity (“HTM”) The Company is required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics. Management classifies the HTM portfolio into the following major security types: U.S. Treasury securities, state and political subdivisions, mortgage-backed securities-residential, mortgage-backed securities-multi-family, corporate debt securities and other securities. Expected losses are calculated on a pooled basis using a probability of default/loss given default (PD/LGD) model, based on historical credit loss data from a reliable source. Management utilizes municipal and corporate default and loss rates which provide decades of data across all municipal and corporate sectors and geographies. Management may exercise discretion to make adjustments based on environmental factors. The model calculates the expected loss for each security over the contractual life. If the risk of a HTM debt security no longer matches the collective assessment pool, it is removed and individually assessed for credit deterioration. U.S. Treasury and mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly and/or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of zero credit losses. Therefore, the Company determined a zero credit loss assumption and did not calculate or record an allowance for credit loss for these securities. Allowance for Credit Losses on Securities Available-for-sale (“AFS”) The credit loss model for AFS debt securities requires credit losses to be presented as an allowance rather than a direct write-down of debt securities. AFS debt securities continue to be recorded at fair value with changes in fair value reflected in other comprehensive income. When the fair value of an AFS debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. The cash flows are estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. Decreases in fair value attributable to credit loss are recorded directly to earnings with a corresponding allowance for credit losses, limited to the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves, the allowance is reversed up to a maximum of the previously recorded credit losses. When the Company intends to sell an impaired AFS debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment will immediately be recognized in earnings with no corresponding allowance for credit losses. Investments in Federal Home Loan Bank (“FHLB”) stock are required for membership and are carried at cost since there is no market value available. The FHLB New York continues to pay dividends and repurchase stock. As such, the Company has not recognized any credit loss on its holdings of FHLB stock. Loans Loans are stated at their amortized basis, which is the amount of unpaid principal balance net of deferred loan origination fees and costs. An accounting policy election was made to exclude accrued interest receivable from the amortized cost basis of loans. Interest on loans is accrued and credited to income based upon the principal amount outstanding. Unearned discount or premium on installment loans is recognized as income or expense over the term of the loan, principally using a method that approximates the effective yield method. Nonrefundable loan fees and related direct costs are deferred and amortized over the life of the loan as an adjustment to loan yield using the effective interest method. Income Recognition on Non-performing and Non-accrual loans The Company generally places a loan on non-accrual status when principal and interest is delinquent for 90 days or more. Any unpaid interest previously accrued on these loans is reversed from income. When a loan is specifically determined to be non-performing, collection of interest and principal are generally applied as a reduction to principal outstanding until the collection of the remaining balance is reasonably assured. Interest income on all non-accrual loans is recognized on a cash basis. Loan Modifications to Borrowers Experiencing Financial Difficulty The Company evaluates loan modifications to borrowers experiencing financial difficulty on the basis and extent of their direct impact on contractual cash flows. Modifications under this guidance include interest rate reductions, payment delays, term extensions, or a combination thereof. Once a loan modification is determined to meet the afore-mentioned criteria, a determination is made as to whether the modification represents the continuation of an existing loan, or a new loan. The Company considers a loan modification to represent the establishment of a new loan if the resulting terms are at least as favorable to the Company as the terms made to other borrowers with similar risk profiles. If a modification is determined to represent a new loan, all unamortized deferred fees and costs are to be recognized through interest income at the time the modification is granted. Modifications that do not meet this criteria shall be considered a continuation of an existing loan, and all unamortized deferred fees and costs will be carried forward as part of the modified loan’s basis. Allowance for Credit Losses on Loans The Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”), “including all subsequent amendments,” approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). The allowance is a valuation account that is deducted from, the loans’ amortized cost basis to present the net, lifetime amount expected to be collected on the loans. Loan losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and amounts expected to be charged-off. Collateral dependent loans that are on non-accrual status with a balance of $250,000 or greater are evaluated on an individual basis and excluded from the pooled loan evaluation. The fair value of collateral for collateral dependent loans less selling costs will be compared to the loan balance to determine if an allowance for credit losses on loans is required. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs. The loan portfolio is segmented based on the level at which the Company develops and documents a systematic methodology to determine its allowance for credit losses. Management developed the following segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined as needed to ensure loans of similar risk profiles are appropriately pooled: residential real estate, commercial real estate, home equity, consumer, and commercial loans. Residential real estate- Residential mortgage and residential construction loans are generally secured by primary liens on the borrower’s residential property. Repayment is primarily dependent on the borrowers’ primary source of income. Significant risk factors include localized economic conditions that may impact the collateralized property’s value, as well as employment prospects for borrowers, regulatory risks specific to housing that may inhibit the Company’s ability to pursue means of repayment, and the accuracy of the estimate of the property’s value at the completion of construction. Commercial real estate- Commercial mortgage and commercial construction loans generally are secured by property either occupied and maintained by the borrower or non-owner occupied, rented to a third-party tenant and managed by the borrower. Repayment cash flow includes rental income from the property, cash flows from the operation of the borrower’s and tenant businesses, and other income sources from the borrower. Significant risks factors include the borrower’s ability to attract and maintain tenants, the borrower’s industry, the successful operation of the borrower’s and tenant businesses, and the accuracy of the estimate of the property’s value at the completion of construction and estimated cost and duration of construction. Home equity- Retail loans that are generally secured by secondary lien positions on 1-4 family residential real estate. Repayment sources primarily rely on the borrowers’ primary source of income and are determined based on the borrower’s equity position in the collateralized property. Default risks are greater, as a borrower is likely to prioritize payments on any outstanding indebtedness on the primary lien position. Additionally, home equity loans are exposed to greater market risk in the event of foreclosure and therefore are more sensitive to changes in underlying collateral valuations. To mitigate this risk the Company, generally does not underwrite terms exceeded 25 years with a loan to value of 85.0% when the Company holds the first mortgage. If the Company does not hold the first mortgage, these loans are underwritten with a higher interest rates and a lower maximum loan to value ratio of 65.0%. Consumer- Retail loans generally consisting of direct loans on new and used automobiles, personal loans that are secured or unsecured, and other consumer installment loans, consisting of passbook loans, unsecured home improvement loans and recreational vehicle loans. Repayment is primarily dependent on borrowers’ primary income source. Economic conditions, as well as specific personal skill sets, can influence a borrower’s ability to maintain adequate employment to finance these loans. Commercial- Commercial purpose loans that are generally secured by the assets other than real estate of borrowers’ businesses. Repayment is primarily the successful operation of the borrower’s business. Business assets may have significant variations in collateral values, and the value that may be realized by the Company, should the need to liquidate arise. Commercial loans are generally underwritten for terms not to exceed 20 years and depend primarily on the creditworthiness and cash flow of the borrower and any guarantors. Management estimates the allowance for credit losses on loans by using relevant information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts that affect the collectability of loans. Historical loss experience was considered by the Company for estimating expected credit losses and determined the need to use peer data, with similar risk profiles, to develop and calculate the ACL on loan models. Historical credit loss experience for the Company and peer losses by loan segments, provide a foundation for estimating an expected credit loss. The observed credit losses are converted to probability of default (“PD”) rate curves through the use of loss given default (“LGD”) risk factors that converts default rates to estimated loss for each loan segment. This is based on industry-level, observed relationships between the PD and LGD variables for each segment. The historical PD curves correspond to economic variables through historical economic cycles, which establishes a quantitative relationship between forecasted economic conditions and loan performance. Using the historical quantitative relationship between economic conditions and loan performance, management developed a model, using selected external economic forecasts that is highly correlated for each loan segment. These forecasts are then applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line methodology. The allowance for credit losses on loans is measured on a collective basis, when similar risk characteristics are present, with both a quantitative and qualitative analysis that is applied on a quarterly basis. The respective quantitative reserve for each segment is calculated using a PD/LGD modeling methodology with segment-specific regression models. The discounted cash flow methodology uses expected credit losses estimated over the effective life of each loan by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level stated interest rate. Management applies a qualitative adjustment for each segment as of the balance sheet date. The qualitative adjustments include limitations inherent in the quantitative model; changes in lending policies and procedures; changes in international, national, regional, and local economic conditions; changes in the nature and volume of the portfolio and terms of loans; the experience, ability and depth of lending management and staff; changes in the volume and severity of past due loans; changes in value of underlying collateral; existence and effect of any concentrations of credit and changes in the levels of such concentrations; and the effect of external factors; such as competition, legal and regulatory requirements. Allowance for Credit Losses on Unfunded Commitments The Company estimates expected credit losses over the contractual period in which the Company has exposure to a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments exposure is recognized in other liabilities and is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over the estimated contractual life. The Company considers the following segments of unfunded commitments exposure; home equity line of credits, commercial line of credits, consumer loans, residential and commercial real estate loans committed but not closed and the unfunded portion of the construction loans. The probable funding amount by segment is multiplied by the respective reserve percentage calculated in the allowance for credit losses on loans to calculate a reserve on unfunded commitments. Accrued Interest Receivable Accrued interest receivable balances are presented separately on the consolidated statements of financial condition and are not included in amortized cost when determining the allowance for credit losses. Accrued interest receivable balances have been excluded from the amortized cost basis of loans and investment securities, and related disclosures. Accrued interest receivable that is deemed uncollectible is written off timely. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore, the amount of such write offs are immaterial. Historically, the Company has not experienced uncollectible accrued interest receivable on investment securities. Foreclosed Real Estate (“FRE”) Foreclosed real estate consists of properties acquired through mortgage loan foreclosure proceedings, deed in lieu of foreclosure or in full or partial satisfaction of loans. FRE is recorded at the estimated fair value of the property less estimated costs to dispose at the time of acquisition to establish a new carrying value. Write downs from the carrying value of the loan to estimated fair value, which are required at the time of foreclosure, are charged to the allowance for credit losses. Subsequent adjustments to the carrying value of such properties resulting from declines in fair value result in the establishment of a valuation allowance and are charged to operations in the period in which the declines occur. Premises and Equipment Land is carried at cost, while buildings, equipment, leasehold improvements and furniture are stated at cost less accumulated depreciation and amortization. Depreciation is computed using principally the straight-line method over the estimated useful lives of the related assets, which range from 15 to 50 years for buildings and from 3 to 10 years for equipment and furniture. Amortization of leasehold improvements and leased equipment is recognized using the straight-line method over the shorter of the lease term or the estimated life of the asset. Maintenance and repairs are typically charged to expense when incurred. Gains and losses from sales or other dispositions of premises and equipment are included in consolidated results of operations. Leases Leases are classified as operating or finance leases. Lease right-of-use (“ROU”) assets and lease liabilities for operating leases are recognized at commencement date based on the present value of lease payments over the lease term, discounted using the Company’s incremental borrowing rate. Operating lease ROU assets are recorded in prepaid expenses and other assets while operating lease liabilities are recorded in other liabilities. The Company has not entered into any finance leases. Options to renew or terminate the lease are recognized as part of ROU assets and liabilities when it is reasonably certain the options will be exercised. The Company has lease agreements that contain both lease and non-lease components, such as maintenance costs, which are accounted for separately. Operating lease expense for fixed lease payments is recognized on a straight-line basis over the lease term. Variable lease payments for real estate taxes, insurance, maintenance and utilities which are generally based on a pro rata share of the total property, are not included in the measurement of the ROU assets or lease liabilities and are expensed as incurred. In addition, the Company does not recognize ROU assets or lease liabilities for short-term leases with a term of 12 months or less, which are also expensed as incurred. Bank Owned Life Insurance The Company has purchased bank-owned life insurance (“BOLI”) as an investment vehicle, on certain current and former officers and executive officers. BOLI is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the cash surrender value are recorded in non-interest income. Treasury Stock Common stock repurchases are recorded at cost and then held as treasury stock. From time to time, the Company may repurchase shares of common stock under an approved plan if, in its judgment, such shares are an attractive investment, in view of the current price at which the common stock is trading relative to the Company’s earnings per share, book value per share and general market and economic factors. On September 17, 2019, the Board of Directors of the Company adopted a stock repurchase program. Under the repurchase program, the Company may repurchase up to 400,000 shares of its common stock. Repurchases are made at management’s discretion at prices management considers to be attractive and in the best interests of both the Company and its stockholders, subject to the availability of stock, general market conditions, the trading price of the stock, alternative uses for capital, and the Company’s financial performance. As of June 30, 2025, the Company had repurchased a total of 48,800 shares of the 400,000 shares authorized by the repurchase program. Federal Home Loan Bank Stock Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost. FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. Impairment of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following: its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position. After evaluating these considerations, the Company concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no impairment charge was recorded during the years ended June 30, 2025 and 2024. Revenue Recognition Revenue from Contracts with Customers (Topic 606), does not apply to the majority of the Company’s revenue-generating transactions, including revenue generated from financial instruments, such as loans and investment securities which are presented in our consolidated statements of income as components of net interest income. All of the Company's revenue from contracts with customers in the scope of Topic 606 is recognized within non-interest income, with the exception of net gains and losses from sales of foreclosed real estate, which is recognized within non-interest expense. The following is a summary of revenues subject to Topic 606 for the years ended June 30, 2025 and 2024. Service Charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are recognized at the time the maintenance occurs. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance. Debit Card Interchange Fee Income: The Company earns interchange fees from debit cardholder transactions conducted through the Visa DPS payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to cardholder. E-commerce Income: The Company earns fees for merchant transaction processing services provided to its business customers by a third-party service provider. The fees represent a percentage of the monthly transaction activity net of related costs, and are received from the service provider on a monthly basis. Investment Services Income: The Company earns fees from investment brokerage services provided to its customers by a third-party service provider. The Company receives commissions from the third-party service provider on a monthly basis based upon customer activity for the month. The Company (i) acts as an agent in arranging the relationship between the customer and the third-party service provider and (ii) does not control the services rendered to the customers. Investment brokerage fees are presented net of related costs. Net Gains/Losses on Sales of Foreclosed Real Estate: The Company records a gain or loss from the sale of foreclosed real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of foreclosed real estate to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the foreclosed real estate asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain or loss on sale if a significant financing component is present. Advertising The Company follows a policy of charging the costs of advertising to expense as incurred. Advertising costs included in advertising and promotion expenses were $486,000 and $445,000 for the years ended June 30, 2025 and 2024, respectively. Derivatives The Company enters into interest rate swap agreements that are not designated as hedges for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not present any material exposure to the Company’s consolidated statements of income. The Company records its interest rate swap agreements at fair value and they are presented on a gross basis within other assets and other liabilities on the consolidated statements of financial condition, as applicable. Changes in the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statements of income. Transfers of Financial Assets Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity. Off-Balance Sheet Credit Related Financial Instruments In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under lines of credit. Such financial instruments are recorded when they are funded. In the normal course of business, the Company utilizes risk participation agreements, which are guarantees issued by the Company to other parties for a fee, whereby the Company agrees to participate in the credit risk of a derivative customer of the other party. Under the terms of these agreements, the “participating bank” receives a fee from the “lead bank” in exchange for the guarantee of reimbursement if the customer defaults on an interest rate swap. The interest rate swap is transacted such that any and all exchanges of interest payments (favorable and unfavorable) are made between the lead bank and the customer. In the event that an early termination of the swap occurs and the customer is unable to make a required close out payment, the participating bank assumes that obligation and is required to make this payment. Income Taxes Provisions for income taxes are accounted for under the asset and liability method and based on taxes currently payable or refundable and deferred income taxes on temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements. Deferred tax assets and liabilities are reported at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled. The Company uses the proportional amortization method for solar tax credit investments, whereby the associated tax credits are recognized as a reduction to tax expense. Certain federal tax credits that are non-refundable and transferable under applicable regulations are accounted for as government grants and recorded as a reduction to the amortized cost or net investment in the applicable asset generating the credit, generally within “other assets.” Amounts are amortized through depreciation or as an adjustment to yield over the estimated life of the asset. Any gain or loss on the transfer of a tax credit is recorded within “other operating income.” Earnings Per Share Basic Earnings Per Share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is computed in a manner similar to that of basic EPS except that the weighted-average number of common shares outstanding is increased to include the number of incremental common shares that would have been outstanding under the treasury stock method if all potentially dilutive common shares (such as stock options) issued became vested during the period. Unallocated common shares held by the ESOP are not included in the weighted-average number of common shares outstanding for either the basic or diluted EPS calculations. See Note 11, Earning Per Share, of this Annual Report. Comprehensive Income (Loss) Comprehensive income (loss) represents net income plus other comprehensive income (loss), which consists primarily of the net change in unrealized gains (losses) on AFS debt securities for the period and changes in the funded status of the Company’s defined benefit pension plan, net of the related tax effect. Impact of Recent Accounting Pronouncements Recent Adopted Accounting Standards In March 2023, the FASB issued ASU 2023-02, Investments – Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures using the Proportional Amortization Method, which permits reporting entities to elect to account for their tax equity investments, regardless of their tax credit program from which the income tax credits are received. The election can be made for each qualifying tax credit investment. Under the proportional amortization method, the initial cost of an investment is amortized in proportion to the amount of tax credits and other tax benefits received, with the amortization and tax credits recognized as a component of income tax expense. To qualify for the proportional amortization method, all of the following conditions must be met: (1) It is probable that the income tax credits allocated to the tax equity investor will be available; (2) The tax equity investor does not have the ability to excise significant influence over the operating and financial policies of the underlying project; (3) Substantially all of the projected benefits are from income tax credits and other income tax benefits; (4) The tax equity investor’s projected yield is based solely on the cash flows from the income tax credits and other income tax benefits is positive; and (5) The tax equity investor is a limited liability investor in the limited liability entity for legal and tax purposes, and the tax equity investor’s liability is limited to its capital investment. A reporting entity that applies the proportional amortization method to qualifying tax equity investments must account for the receipt of the investment tax credits using the flow-through method under Topic 740, Income Taxes. The amendments also require the application of the delayed equity contribution guidance to all tax equity investments, and require specific disclosures that must be applied to all investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method in accordance with Subtopic 323-740. Under the proportional amortization method, the investment shall be tested for impairment when events or changes in circumstances indicate that is more likely than not that the carrying amount of the investment will not be realized. An impairment loss shall be measured as the amount by which the carrying amount of the investment exceeds its fair value. A previously recognized impairment loss shall not be reversed. The Company adopted ASU 2023-02 during the quarter ended September 30, 2024. The Company’s adoption of this standard did not have a material impact on the consolidated financial statements. In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures, to improve the reportable segment disclosures by requiring disclosure of incremental segment information on an annual and interim basis. In addition, the amendments will enhance interim disclosure requirements, clarify circumstances in which an entity can disclose multiple segment measures of profit or loss, provide new segment disclosure requirements for entities with a single reportable segment and contain other disclosure requirements. The amendments in this ASU are effective for annual periods beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company adopted ASU 2023-07 during the year ended June 30, 2025. The Company’s adoption of this standard did not have a material impact on the consolidated financial statements. Accounting Standards Issued Not Yet Adopted In October 2023, the FASB issued ASU 2023-06, Disclosure Improvements, which amends the disclosure or presentation requirements related to various subtopics in the FASB Accounting Standards Codification. The ASU was issued in response to the SEC’s August 2018 final rule that updated and simplified disclosure requirements that the SEC believed were redundant, duplicative, overlapping, outdated, or superseded. The new guidance is intended to align GAAP requirements with those of the SEC. The ASU will become effective on the earlier of the date on which the SEC removes its disclosure requirements for the related disclosure or June 30, 2027. Early adoption is not permitted. The adoption is not expected to have a material impact on the consolidated financial statements. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures, which will require public entities to disclose annually a tabular rate reconciliation, including specific items such as state and local income tax, tax credits, nontaxable or nondeductible items, among others, and a separate disclosure requiring disaggregation of reconciling items as described above which equal or exceed 5.0% of the product of multiplying income from continuing operations by the applicable statutory income tax rate. The ASU is effective for annual periods beginning after December 31, 2024. The adoption is not expected to have a material impact on the consolidated financial statements.

The consolidated financial statements include the accounts of certain Variable Interest Entities (“VIE(s)”). In accordance with the applicable accounting guidance for consolidations, the Company consolidates a VIE if it has (i) a variable interest in the entity; (ii) the power to direct activities of the VIE that most significantly affect the entity’s economic performance; and (iii) the obligation to absorb losses of the entity or the right to receive benefits from the entity that could potentially be significant to the VIE (i.e., we are considered to be the primary beneficiary).

The Company uses the equity method to account for unconsolidated investments in VIEs if it has significant influence over the entity’s operating and financing decision. Unconsolidated investments in VIEs in which the Company does not have significant influence, are carried at a cost measurement alternative. See Note 14, Variable Interest Entities for information on our involvement with VIEs.

The Company’s primary business is the ownership and operation of its subsidiaries. At June 30, 2025, the Company operated 18 full-service banking offices, lending centers, an operations center, customer call center, administration center, and a wealth management center located in its market area consisting of the Hudson Valley and Capital District Regions of New York State. The Bank is primarily engaged in the business of attracting deposits from the general public in the Bank’s market area, and investing such deposits, together with other sources of funds, in loans and investment securities. The Commercial Bank’s primary business is to attract deposits from and provide banking services to local municipalities. Greene Property Holdings, Ltd. was formed as a New York corporation that has elected under the Internal Revenue Code to be a real estate investment trust. Currently, certain mortgages and loan notes held by the Bank are transferred and beneficially owned by Greene Property Holdings, Ltd. The Bank continues to service these loans.

The Company and its parent mutual holding company, Greene County Bancorp, MHC (the “MHC”) are federally chartered and regulated and examined by the Federal Reserve Board. The Bank, the subsidiary of the Company, is also federally chartered and is regulated and examined by the Office of the Comptroller of the Currency (the “OCC”).

As a federal savings association, the Bank must satisfy the qualified thrift lender, or “QTL”, requirement by meeting one of two tests: the Home Owners’ Loan Act (“HOLA”) QTL test or the Internal Revenue Service (IRS) Domestic Building and Loan Association (DBLA) test. The federal savings association may use either test to qualify and may switch from one test to the other.

Under the HOLA QTL test, the Bank must maintain at least 65.0% of its “portfolio assets” in “qualified thrift investments” in at least nine of the most recent 12-month period. “Portfolio assets” generally means total assets of a savings institution, less the sum of specified liquid assets up to 20.0% of total assets, goodwill and other intangible assets, and the value of property used in the conduct of the savings association’s business.

“Qualified thrift investments” include various types of loans made for residential and housing purposes, investments related to such purposes, including certain mortgage-backed and related securities, and loans for personal, family, household and certain other purposes up to a limit of 20.0% of portfolio assets. “Qualified thrift investments” also include 100.0% of an institution’s credit card loans, education loans and small business loans.

Under the IRS DBLA test, the Bank must meet the business operations test and the 60.0% of assets test. The business operations test requires that the federal savings association’s business consists primarily of acquiring the savings of the public (75.0% of its deposits, withdrawable shares, and other obligations must be held by the general public) and investing in loans (more than 75.0% of its gross income consists of interest on loans and government obligations and various other specified types of operating income that federal savings associations ordinarily earn). For the 60.0% of assets test, the Bank must maintain at least 60.0% of its total in “qualified investments” as of the close of the taxable year or, at the option of the taxpayer, may be computed on the basis of the average assets outstanding during the taxable year.

In accordance with ASU 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures, the Company operates as a single operating segment, banking, providing financial services to retail, municipal and commercial customers in its market area, consisting of the Hudson Valley and Capital District Regions of New York State. The Company derives the majority of its revenue from banking operations within the local market.

The Company’s Chief Executive Officer (“CEO”) is designated as the Company’s Chief Operating Decision Maker (“CODM”). The CODM evaluates financial performance and allocates resources by reviewing the consolidated financial statements of the Company, analyzing revenue, expenses, capital levels and budget to actual variances.

The Company has classified its investments in debt securities as either available-for-sale or held-to-maturity and equity securities. Securities available-for-sale are reported at fair value, with net unrealized gains and losses reflected in the accumulated other comprehensive loss component of shareholders’ equity, net of applicable income taxes. Securities held-to-maturity are those debt securities which management has the intent and the ability to hold to maturity and are reported at amortized cost. Equity securities are recorded at fair value, with net unrealized gains and losses recognized in income. The Company does not have trading securities in its portfolio.

Realized gains or losses on security transactions are reported in earnings and computed using the specific identification cost basis. Fair values of securities are based on quoted market prices, where available. Valuation of securities is further described in Note 18, Fair Value Measurements and Fair Value of Financial Instruments, of this Annual Report. Amortization of bond premiums and accretion of bond discounts are amortized over the expected life of the securities using the interest method. Dividend and interest income are recognized when collected.

The Company is required to utilize the CECL approach to estimate expected credit losses. Management measures expected credit losses on HTM debt securities on a collective basis by major security types that share similar risk characteristics. Management classifies the HTM portfolio into the following major security types: U.S. Treasury securities, state and political subdivisions, mortgage-backed securities-residential, mortgage-backed securities-multi-family, corporate debt securities and other securities.

Expected losses are calculated on a pooled basis using a probability of default/loss given default (PD/LGD) model, based on historical credit loss data from a reliable source. Management utilizes municipal and corporate default and loss rates which provide decades of data across all municipal and corporate sectors and geographies. Management may exercise discretion to make adjustments based on environmental factors. The model calculates the expected loss for each security over the contractual life. If the risk of a HTM debt security no longer matches the collective assessment pool, it is removed and individually assessed for credit deterioration.

U.S. Treasury and mortgage-backed securities are issued by U.S. government entities and agencies. These securities are either explicitly and/or implicitly guaranteed by the U.S. government as to timely repayment of principal and interest, are highly rated by major rating agencies, and have a long history of zero credit losses. Therefore, the Company determined a zero credit loss assumption and did not calculate or record an allowance for credit loss for these securities.

The credit loss model for AFS debt securities requires credit losses to be presented as an allowance rather than a direct write-down of debt securities. AFS debt securities continue to be recorded at fair value with changes in fair value reflected in other comprehensive income. When the fair value of an AFS debt security falls below the amortized cost basis it is evaluated to determine if any of the decline in value is attributable to credit loss. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. The cash flows are estimated using information relevant to the collectability of the security, including information about past events, current conditions and reasonable and supportable forecasts. Decreases in fair value attributable to credit loss are recorded directly to earnings with a corresponding allowance for credit losses, limited to the amount that the fair value is less than the amortized cost basis. If the credit quality subsequently improves, the allowance is reversed up to a maximum of the previously recorded credit losses. When the Company intends to sell an impaired AFS debt security, or if it is more likely than not that the Company will be required to sell the security prior to recovering the amortized cost basis, the entire fair value adjustment will immediately be recognized in earnings with no corresponding allowance for credit losses.

Investments in Federal Home Loan Bank (“FHLB”) stock are required for membership and are carried at cost since there is no market value available. The FHLB New York continues to pay dividends and repurchase stock. As such, the Company has not recognized any credit loss on its holdings of FHLB stock.

Loans are stated at their amortized basis, which is the amount of unpaid principal balance net of deferred loan origination fees and costs. An accounting policy election was made to exclude accrued interest receivable from the amortized cost basis of loans. Interest on loans is accrued and credited to income based upon the principal amount outstanding. Unearned discount or premium on installment loans is recognized as income or expense over the term of the loan, principally using a method that approximates the effective yield method. Nonrefundable loan fees and related direct costs are deferred and amortized over the life of the loan as an adjustment to loan yield using the effective interest method.

The Company generally places a loan on non-accrual status when principal and interest is delinquent for 90 days or more. Any unpaid interest previously accrued on these loans is reversed from income. When a loan is specifically determined to be non-performing, collection of interest and principal are generally applied as a reduction to principal outstanding until the collection of the remaining balance is reasonably assured. Interest income on all non-accrual loans is recognized on a cash basis.

Once a loan modification is determined to meet the afore-mentioned criteria, a determination is made as to whether the modification represents the continuation of an existing loan, or a new loan. The Company considers a loan modification to represent the establishment of a new loan if the resulting terms are at least as favorable to the Company as the terms made to other borrowers with similar risk profiles. If a modification is determined to represent a new loan, all unamortized deferred fees and costs are to be recognized through interest income at the time the modification is granted. Modifications that do not meet this criteria shall be considered a continuation of an existing loan, and all unamortized deferred fees and costs will be carried forward as part of the modified loan’s basis.

The Accounting Standards Update (“ASU”) 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“CECL”), “including all subsequent amendments,” approach requires an estimate of the credit losses expected over the life of a loan (or pool of loans). The allowance is a valuation account that is deducted from, the loans’ amortized cost basis to present the net, lifetime amount expected to be collected on the loans. Loan losses are charged off against the allowance when management believes a loan balance is confirmed to be uncollectible. Expected recoveries do not exceed the aggregate of amounts previously charged-off and amounts expected to be charged-off.

Collateral dependent loans that are on non-accrual status with a balance of $250,000 or greater are evaluated on an individual basis and excluded from the pooled loan evaluation. The fair value of collateral for collateral dependent loans less selling costs will be compared to the loan balance to determine if an allowance for credit losses on loans is required. When management determines that foreclosure is probable, expected credit losses are based on the fair value of the collateral at the reporting date, adjusted for selling costs.

The loan portfolio is segmented based on the level at which the Company develops and documents a systematic methodology to determine its allowance for credit losses. Management developed the following segments for estimating loss based on type of borrower and collateral which is generally based upon federal call report segmentation and have been combined as needed to ensure loans of similar risk profiles are appropriately pooled: residential real estate, commercial real estate, home equity, consumer, and commercial loans.

Residential real estate- Residential mortgage and residential construction loans are generally secured by primary liens on the borrower’s residential property. Repayment is primarily dependent on the borrowers’ primary source of income. Significant risk factors include localized economic conditions that may impact the collateralized property’s value, as well as employment prospects for borrowers, regulatory risks specific to housing that may inhibit the Company’s ability to pursue means of repayment, and the accuracy of the estimate of the property’s value at the completion of construction.

Commercial real estate- Commercial mortgage and commercial construction loans generally are secured by property either occupied and maintained by the borrower or non-owner occupied, rented to a third-party tenant and managed by the borrower. Repayment cash flow includes rental income from the property, cash flows from the operation of the borrower’s and tenant businesses, and other income sources from the borrower. Significant risks factors include the borrower’s ability to attract and maintain tenants, the borrower’s industry, the successful operation of the borrower’s and tenant businesses, and the accuracy of the estimate of the property’s value at the completion of construction and estimated cost and duration of construction.

Home equity- Retail loans that are generally secured by secondary lien positions on 1-4 family residential real estate. Repayment sources primarily rely on the borrowers’ primary source of income and are determined based on the borrower’s equity position in the collateralized property. Default risks are greater, as a borrower is likely to prioritize payments on any outstanding indebtedness on the primary lien position. Additionally, home equity loans are exposed to greater market risk in the event of foreclosure and therefore are more sensitive to changes in underlying collateral valuations. To mitigate this risk the Company, generally does not underwrite terms exceeded 25 years with a loan to value of 85.0% when the Company holds the first mortgage. If the Company does not hold the first mortgage, these loans are underwritten with a higher interest rates and a lower maximum loan to value ratio of 65.0%.

Consumer- Retail loans generally consisting of direct loans on new and used automobiles, personal loans that are secured or unsecured, and other consumer installment loans, consisting of passbook loans, unsecured home improvement loans and recreational vehicle loans. Repayment is primarily dependent on borrowers’ primary income source. Economic conditions, as well as specific personal skill sets, can influence a borrower’s ability to maintain adequate employment to finance these loans.

Commercial- Commercial purpose loans that are generally secured by the assets other than real estate of borrowers’ businesses. Repayment is primarily the successful operation of the borrower’s business. Business assets may have significant variations in collateral values, and the value that may be realized by the Company, should the need to liquidate arise. Commercial loans are generally underwritten for terms not to exceed 20 years and depend primarily on the creditworthiness and cash flow of the borrower and any guarantors.

Management estimates the allowance for credit losses on loans by using relevant information, from internal and external sources, related to past events, current conditions, and reasonable and supportable forecasts that affect the collectability of loans. Historical loss experience was considered by the Company for estimating expected credit losses and determined the need to use peer data, with similar risk profiles, to develop and calculate the ACL on loan models.

Historical credit loss experience for the Company and peer losses by loan segments, provide a foundation for estimating an expected credit loss. The observed credit losses are converted to probability of default (“PD”) rate curves through the use of loss given default (“LGD”) risk factors that converts default rates to estimated loss for each loan segment. This is based on industry-level, observed relationships between the PD and LGD variables for each segment. The historical PD curves correspond to economic variables through historical economic cycles, which establishes a quantitative relationship between forecasted economic conditions and loan performance.

Using the historical quantitative relationship between economic conditions and loan performance, management developed a model, using selected external economic forecasts that is highly correlated for each loan segment. These forecasts are then applied over a period that management has determined to be reasonable and supportable. Beyond the period over which management can develop or source a reasonable and supportable forecast, the model will revert to long-term average economic conditions using a straight-line methodology.

The allowance for credit losses on loans is measured on a collective basis, when similar risk characteristics are present, with both a quantitative and qualitative analysis that is applied on a quarterly basis. The respective quantitative reserve for each segment is calculated using a PD/LGD modeling methodology with segment-specific regression models. The discounted cash flow methodology uses expected credit losses estimated over the effective life of each loan by measuring the difference between the net present value of modeled cash flows and amortized cost basis. Contractual cash flows over the contractual life of the loans are the basis for modeled cash flows, adjusted for modeled defaults and expected prepayments and discounted at the loan-level stated interest rate.

Management applies a qualitative adjustment for each segment as of the balance sheet date. The qualitative adjustments include limitations inherent in the quantitative model; changes in lending policies and procedures; changes in international, national, regional, and local economic conditions; changes in the nature and volume of the portfolio and terms of loans; the experience, ability and depth of lending management and staff; changes in the volume and severity of past due loans; changes in value of underlying collateral; existence and effect of any concentrations of credit and changes in the levels of such concentrations; and the effect of external factors; such as competition, legal and regulatory requirements.

The Company estimates expected credit losses over the contractual period in which the Company has exposure to a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company. The allowance for credit losses on unfunded commitments exposure is recognized in other liabilities and is adjusted as an expense in other noninterest expense. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over the estimated contractual life. The Company considers the following segments of unfunded commitments exposure; home equity line of credits, commercial line of credits, consumer loans, residential and commercial real estate loans committed but not closed and the unfunded portion of the construction loans. The probable funding amount by segment is multiplied by the respective reserve percentage calculated in the allowance for credit losses on loans to calculate a reserve on unfunded commitments.

Accrued interest receivable balances are presented separately on the consolidated statements of financial condition and are not included in amortized cost when determining the allowance for credit losses. Accrued interest receivable balances have been excluded from the amortized cost basis of loans and investment securities, and related disclosures. Accrued interest receivable that is deemed uncollectible is written off timely. For loans, write off typically occurs upon becoming over 90 to 120 days past due and therefore, the amount of such write offs are immaterial. Historically, the Company has not experienced uncollectible accrued interest receivable on investment securities.

Foreclosed real estate consists of properties acquired through mortgage loan foreclosure proceedings, deed in lieu of foreclosure or in full or partial satisfaction of loans. FRE is recorded at the estimated fair value of the property less estimated costs to dispose at the time of acquisition to establish a new carrying value. Write downs from the carrying value of the loan to estimated fair value, which are required at the time of foreclosure, are charged to the allowance for credit losses. Subsequent adjustments to the carrying value of such properties resulting from declines in fair value result in the establishment of a valuation allowance and are charged to operations in the period in which the declines occur.

Land is carried at cost, while buildings, equipment, leasehold improvements and furniture are stated at cost less accumulated depreciation and amortization. Depreciation is computed using principally the straight-line method over the estimated useful lives of the related assets, which range from 15 to 50 years for buildings and from 3 to 10 years for equipment and furniture. Amortization of leasehold improvements and leased equipment is recognized using the straight-line method over the shorter of the lease term or the estimated life of the asset. Maintenance and repairs are typically charged to expense when incurred. Gains and losses from sales or other dispositions of premises and equipment are included in consolidated results of operations.

Leases are classified as operating or finance leases. Lease right-of-use (“ROU”) assets and lease liabilities for operating leases are recognized at commencement date based on the present value of lease payments over the lease term, discounted using the Company’s incremental borrowing rate. Operating lease ROU assets are recorded in prepaid expenses and other assets while operating lease liabilities are recorded in other liabilities. The Company has not entered into any finance leases. Options to renew or terminate the lease are recognized as part of ROU assets and liabilities when it is reasonably certain the options will be exercised. The Company has lease agreements that contain both lease and non-lease components, such as maintenance costs, which are accounted for separately. Operating lease expense for fixed lease payments is recognized on a straight-line basis over the lease term. Variable lease payments for real estate taxes, insurance, maintenance and utilities which are generally based on a pro rata share of the total property, are not included in the measurement of the ROU assets or lease liabilities and are expensed as incurred. In addition, the Company does not recognize ROU assets or lease liabilities for short-term leases with a term of 12 months or less, which are also expensed as incurred.

The Company has purchased bank-owned life insurance (“BOLI”) as an investment vehicle, on certain current and former officers and executive officers. BOLI is recorded at the amount that can be realized under the insurance contracts at the balance sheet date, which is the cash surrender value adjusted for other charges or other amounts due that are probable at settlement. Changes in the cash surrender value are recorded in non-interest income.

Common stock repurchases are recorded at cost and then held as treasury stock. From time to time, the Company may repurchase shares of common stock under an approved plan if, in its judgment, such shares are an attractive investment, in view of the current price at which the common stock is trading relative to the Company’s earnings per share, book value per share and general market and economic factors. On September 17, 2019, the Board of Directors of the Company adopted a stock repurchase program. Under the repurchase program, the Company may repurchase up to 400,000 shares of its common stock. Repurchases are made at management’s discretion at prices management considers to be attractive and in the best interests of both the Company and its stockholders, subject to the availability of stock, general market conditions, the trading price of the stock, alternative uses for capital, and the Company’s financial performance. As of June 30, 2025, the Company had repurchased a total of 48,800 shares of the 400,000 shares authorized by the repurchase program.

Federal law requires a member institution of the Federal Home Loan Bank (“FHLB”) system to hold stock of its district FHLB according to a predetermined formula. This stock is restricted in that it can only be sold to the FHLB or to another member institution, and all sales of FHLB stock must be at par. As a result of these restrictions, FHLB stock is carried at cost. FHLB stock is held as a long-term investment and its value is determined based on the ultimate recoverability of the par value. Impairment of this investment is evaluated quarterly and is a matter of judgment that reflects management’s view of the FHLB’s long-term performance, which includes factors such as the following: its operating performance; the severity and duration of declines in the fair value of its net assets related to its capital stock amount; its commitment to make payments required by law or regulation and the level of such payments in relation to its operating performance; the impact of legislative and regulatory changes on the FHLB, and accordingly, on the members of the FHLB; and its liquidity and funding position. After evaluating these considerations, the Company concluded that the par value of its investment in FHLB stock will be recovered and, therefore, no impairment charge was recorded during the years ended June 30, 2025 and 2024.

Revenue from Contracts with Customers (Topic 606), does not apply to the majority of the Company’s revenue-generating transactions, including revenue generated from financial instruments, such as loans and investment securities which are presented in our consolidated statements of income as components of net interest income. All of the Company's revenue from contracts with customers in the scope of Topic 606 is recognized within non-interest income, with the exception of net gains and losses from sales of foreclosed real estate, which is recognized within non-interest expense. The following is a summary of revenues subject to Topic 606 for the years ended June 30, 2025 and 2024.

Service Charges on Deposit Accounts: The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payment charges, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer's request. Account maintenance fees, which relate primarily to monthly maintenance, are recognized at the time the maintenance occurs. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer's account balance.

Debit Card Interchange Fee Income: The Company earns interchange fees from debit cardholder transactions conducted through the Visa DPS payment network. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to cardholder.

E-commerce Income: The Company earns fees for merchant transaction processing services provided to its business customers by a third-party service provider. The fees represent a percentage of the monthly transaction activity net of related costs, and are received from the service provider on a monthly basis.

Investment Services Income: The Company earns fees from investment brokerage services provided to its customers by a third-party service provider. The Company receives commissions from the third-party service provider on a monthly basis based upon customer activity for the month. The Company (i) acts as an agent in arranging the relationship between the customer and the third-party service provider and (ii) does not control the services rendered to the customers. Investment brokerage fees are presented net of related costs.

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

The Company enters into interest rate swap agreements that are not designated as hedges for accounting purposes. As the interest rate swap agreements have substantially equivalent and offsetting terms, they do not present any material exposure to the Company’s consolidated statements of income. The Company records its interest rate swap agreements at fair value and they are presented on a gross basis within other assets and other liabilities on the consolidated statements of financial condition, as applicable. Changes in the fair value of assets and liabilities arising from these derivatives are included, net, in other operating income in the consolidated statements of income.

Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of the right) to pledge or exchange the transferred assets, and (3) the Company does not maintain effective control over the transferred assets through an agreement to repurchase them before their maturity.

In the ordinary course of business, the Company has entered into commitments to extend credit, including commitments under lines of credit. Such financial instruments are recorded when they are funded. In the normal course of business, the Company utilizes risk participation agreements, which are guarantees issued by the Company to other parties for a fee, whereby the Company agrees to participate in the credit risk of a derivative customer of the other party. Under the terms of these agreements, the “participating bank” receives a fee from the “lead bank” in exchange for the guarantee of reimbursement if the customer defaults on an interest rate swap. The interest rate swap is transacted such that any and all exchanges of interest payments (favorable and unfavorable) are made between the lead bank and the customer. In the event that an early termination of the swap occurs and the customer is unable to make a required close out payment, the participating bank assumes that obligation and is required to make this payment.

Provisions for income taxes are accounted for under the asset and liability method and based on taxes currently payable or refundable and deferred income taxes on temporary differences between the tax basis of assets and liabilities and their reported amounts in the consolidated financial statements. Deferred tax assets and liabilities are reported at currently enacted income tax rates applicable to the period in which the deferred tax assets and liabilities are expected to be realized or settled.

The Company uses the proportional amortization method for solar tax credit investments, whereby the associated tax credits are recognized as a reduction to tax expense. Certain federal tax credits that are non-refundable and transferable under applicable regulations are accounted for as government grants and recorded as a reduction to the amortized cost or net investment in the applicable asset generating the credit, generally within “other assets.” Amounts are amortized through depreciation or as an adjustment to yield over the estimated life of the asset. Any gain or loss on the transfer of a tax credit is recorded within “other operating income.”

Basic Earnings Per Share (“EPS”) is computed by dividing net income by the weighted average number of common shares outstanding during the period. Diluted EPS is computed in a manner similar to that of basic EPS except that the weighted-average number of common shares outstanding is increased to include the number of incremental common shares that would have been outstanding under the treasury stock method if all potentially dilutive common shares (such as stock options) issued became vested during the period. Unallocated common shares held by the ESOP are not included in the weighted-average number of common shares outstanding for either the basic or diluted EPS calculations. See Note 11, Earning Per Share, of this Annual Report.

Comprehensive income (loss) represents net income plus other comprehensive income (loss), which consists primarily of the net change in unrealized gains (losses) on AFS debt securities for the period and changes in the funded status of the Company’s defined benefit pension plan, net of the related tax effect.

In March 2023, the FASB issued ASU 2023-02, Investments – Equity Method and Joint Ventures (Topic 323), Accounting for Investments in Tax Credit Structures using the Proportional Amortization Method, which permits reporting entities to elect to account for their tax equity investments, regardless of their tax credit program from which the income tax credits are received. The election can be made for each qualifying tax credit investment. Under the proportional amortization method, the initial cost of an investment is amortized in proportion to the amount of tax credits and other tax benefits received, with the amortization and tax credits recognized as a component of income tax expense. To qualify for the proportional amortization method, all of the following conditions must be met: (1) It is probable that the income tax credits allocated to the tax equity investor will be available; (2) The tax equity investor does not have the ability to excise significant influence over the operating and financial policies of the underlying project; (3) Substantially all of the projected benefits are from income tax credits and other income tax benefits; (4) The tax equity investor’s projected yield is based solely on the cash flows from the income tax credits and other income tax benefits is positive; and (5) The tax equity investor is a limited liability investor in the limited liability entity for legal and tax purposes, and the tax equity investor’s liability is limited to its capital investment.

A reporting entity that applies the proportional amortization method to qualifying tax equity investments must account for the receipt of the investment tax credits using the flow-through method under Topic 740, Income Taxes. The amendments also require the application of the delayed equity contribution guidance to all tax equity investments, and require specific disclosures that must be applied to all investments that generate income tax credits and other income tax benefits from a tax credit program for which the entity has elected to apply the proportional amortization method in accordance with Subtopic 323-740.

Under the proportional amortization method, the investment shall be tested for impairment when events or changes in circumstances indicate that is more likely than not that the carrying amount of the investment will not be realized. An impairment loss shall be measured as the amount by which the carrying amount of the investment exceeds its fair value. A previously recognized impairment loss shall not be reversed.
