Presentation of Interim Information
Presentation of Interim Information	1. Presentation of Interim Information First Savings Financial Group, Inc. (the “Company”) is a financial holding company and the parent of First Savings Bank (the “Bank”). The Bank, which is a wholly-owned Indiana-chartered commercial bank subsidiary of the Company, provides a variety of banking services to individuals and business customers through 16 locations in southern Indiana. The Bank attracts deposits primarily from the general public and uses those funds, along with other borrowings, primarily to originate commercial mortgage, residential mortgage, construction, commercial business and consumer loans, and to a lesser extent, to invest in mortgage-backed securities, municipal bonds and other investment securities. The Bank has three wholly-owned subsidiaries: Q2 Business Capital, LLC(“Q2”), an Indiana limited liability company that specializes in the origination and servicing of U.S. Small Business Administration (“SBA”) loans, First Savings Investments, Inc., a Nevada corporation that manages a securities portfolio, and Southern Indiana Financial Corporation, which is currently inactive. First Savings Insurance Risk Management, Inc. (the “Captive”), which was a wholly-owned insurance subsidiary of the Company, was a Nevada corporation that provided property and casualty insurance to the Company, the Bank and the Bank’s active subsidiaries. In addition, the Captive provided reinsurance to 11 other third-party insurance captives for which insurance may not be currently available or economically feasible in the insurance marketplace.Effective September 30, 2023, the Captive was dissolved and is no longer in existence. During the three-month period ended December 31, 2023, the Bank ceased its national originate-to-sell mortgage banking operation. The Bank continues to originate residential mortgage loans in its local southern Indiana market and first-lien home equity lines of credit from its loan production office in Franklin, Tennessee. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments considered necessary to present fairly the financial position as of December 31, 2024, the results of operations for the three-month periods ended December 31, 2024 and 2023, and the cash flows for the three-month periods ended December 31, 2024 and 2023. All of these adjustments are of a normal, recurring nature. Such adjustments are the only adjustments included in the unaudited condensed consolidated financial statements. Interim results are not necessarily indicative of results for a full year. The unaudited condensed consolidated financial statements and notes have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial statements, conform to general practices within the banking industry and are presented as permitted by the instructions to Form 10-Q. Accordingly, they do not contain certain information included in the Company’s audited consolidated financial statements and related notes for the year ended September 30, 2024 included in the Company’s Annual Report on Form 10-K. The unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All material intercompany balances and transactions have been eliminated in consolidation. Loans and Allowance for Credit Losses Loans Held for Investment Loans are stated at unpaid principal balances, less net deferred loan fees and the allowance for credit losses. Loan origination and commitment fees, as well as certain direct costs of underwriting and closing loans, are deferred and amortized as a yield adjustment to interest income over the lives of the related loans using the interest method. Amortization of deferred loan fees is discontinued when a loan is placed on nonaccrual status. Nonaccrual Loans The recognition of income on a loan is discontinued and previously accrued interest is reversed when interest or principal payments become 90 days past due unless, in the opinion of management, the outstanding interest remains collectible and is well secured and in process of collection. Past due status is determined based on contractual terms. Generally, by applying the cash receipts method, interest income on nonaccrual loans is subsequently recognized only as received until the loan is returned to accrual status. The cash receipts method is used when the likelihood of further loss on the loan is remote. Otherwise, the Company applies the cost recovery method and applies all payments as a reduction of the unpaid principal balance until the loan qualifies for return to accrual status. A loan is restored to accrual status when all principal and interest payments are brought current and the borrower has demonstrated the ability to make future payments of principal and interest as scheduled, which generally requires that the borrower demonstrate a period of performance of at least six consecutive months. Loan Charge-Offs For portfolio segments other than consumer loans, the Company’s practice is to charge-off any loan or portion of a loan when the loan is determined by management to be uncollectible due to the borrower’s failure to meet repayment terms, the borrower’s deteriorating or deteriorated financial condition, depreciation of the underlying collateral or for other reasons. A partial charge-off is recorded on a loan when the uncollectibility of a portion of the loan has been confirmed, such as when a loan is discharged in bankruptcy, the collateral is liquidated, a loan is restructured at a reduced principal balance, or other identifiable events that lead management to determine the full principal balance of the loan will not likely be repaid. A specific reserve is recognized as a component of the allowance for estimated losses on loans individually evaluated for impairment. Consumer loans not secured by real estate are typically charged off at 90 days past due, or earlier if deemed uncollectible, unless the loans are in the process of collection. Overdrafts are charged off after 45 days past due. Charge-offs are typically recorded on loans secured by real estate when the property is foreclosed upon when the carrying value of the loan exceeds the property’s fair value, less estimated costs to sell. Allowance for Credit Losses – Loans The allowance for credit losses (ACL) is a valuation account that is deducted from the loans’ amortized cost basis to present the net amount expected to be collected on the loans. The ACL is increased by provision expense and decreased by charge-offs, net of recoveries of amounts previously charged off. The Company follows its nonaccrual policy by reversing contractual interest income in the income statement when the Company places a loan on nonaccrual status. Therefore, management excludes the accrued interest receivable balance from the amortized cost basis in measuring expected credit losses on the portfolio and does not record an allowance for credit losses on accrued interest receivable. Management considers forward-looking information in estimating expected credit losses. For the contractual term that extends beyond the reasonable and supportable forecast period, the Company reverts to the long term average of historical factors using a four-quarter forecast with immediate reversion to historical losses. Management estimates the ACL balance using relevant available information from both internal and external sources, relating to past events, current conditions and reasonable and supportable forecasts. Historical credit loss experience paired with economic forecasts provides the basis for the quantitatively modeled estimates of expected credit losses. The Company adjusts its quantitative model, as necessary, to reflect conditions not already considered by the quantitative model. The adjustments are commonly known as the Qualitative Framework. The ACL model for each segment is adjusted for (1) changes in the Company’s lending policy, (2) changes in international, national, regional and local economic conditions, (3) changes in the nature and volume of the portfolio and terms of loans, (4) changes in the experience, depth and ability of lending management, (5) changes in the volume and severity of past due loans and other similar conditions, (6) changes in the quality of the Company’s loan review system, (7) changes in the value of underlying collateral, (8) the existence and effect of any concentrations of credit and changes in the levels of such concentrations and (9) the effect of other external factors such as competition, legal and regulatory requirements. The ACL is measured on a collective (pool) basis when similar risk characteristics exist utilizing a weighted average remaining maturity loss methodology.The ACL utilizes historical charge off rates that were internally calculated as well as peer charge off data. In many cases, the peer data, which showed higher loss rates, was utilized due to representing a better approximation of management’s estimate of the expected losses on the loan segments. For loans evaluated on a pool basis, the Company applies an average historical loss rate to the pool over its estimated remaining life assuming a constant attrition rate. Loans that do not share risk characteristics are evaluated on an individual basis. The Company maintains a net book balance threshold of $500,000 for individually evaluated loans unless further analysis in the future suggests a change is needed to this threshold based on the credit environment at that time. For collateral dependent financial assets where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the financial asset to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral and the amortized cost basis of the asset as of the measurement date. When repayment is expected to be from the operation of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the present value of expected cash flows from the operation of the collateral. When repayment is expected to be from the sale of the collateral, expected credit losses are calculated as the amount by which the amortized cost basis of the financial asset exceeds the fair value of the underlying collateral less estimated cost to sell. The allowance for credit losses may be zero if the fair value of the collateral at the measurement date exceeds the amortized cost basis of the financial asset. If the loan is not collateral dependent, the measurement of loss is based on the difference between the expected and contractual future cash flows of the loan. Management measures expected credit losses over the contractual term of a loan. When determining the contractual term, the Company considers expected prepayments but is precluded from considering expected extensions, renewals or modifications, unless the Company reasonably expects it will execute a loan modification with a borrower. In the event of a reasonably expected loan modification, the Company factors the reasonably-expected loan modification into the current expected credit losses estimate. The Company has identified the following portfolio segments and measures and adjusts the ACL using the following methods: Residential real estate The residential real estate ACL model is adjusted for forecasted changes in the housing price indices at both the national and local level, the Case-Schiller Home Price Index, the national unemployment rate, Consumer Price Index (“CPI”) and Real Gross Domestic Product (“Real GDP”). Commercial real estate, single tenant net lease and multifamily The Company offers multi-family mortgage loans that are generally secured by properties in our primary market area. Multi-family loans are secured by first mortgages and generally are originated with a maximum loan-to-value ratio of 80% and generally require specified debt service coverage ratios depending on the characteristics of the project. The Company offers single tenant net lease loans, which are derived from a commercial real estate lending program that is focused on loans to high net worth individuals and that are secured by low loan-to-value, single-tenant commercial properties that are generally leased to investment grade national-brand retailers, the borrowers and collateral properties for which are outside of our primary market area (“NNN Finance Program”). This program is designed to diversify the Company’s geographic and credit risk profile given the geographic dispersion of the loans and collateral, and the investment grade credit of the national-brand lessees. The terms of the loans are generally consistent with the aforementioned terms of in-market commercial real estate loans; however, these cannot exceed 70% loan-to-value and loan maturities cannot exceed the expiration of the underlying leases. The commercial real estate, single tenant net lease and multi-family ACL models are adjusted for changes in the Commercial Real Estate Price Index, which is a time series of commercial property values prepared by the Board of Governors of the Federal Reserve System, and the national unemployment rate, CPI and Real GDP. SBA commercial real estate and SBA commercial business The SBA commercial real estate ACL model is adjusted for the Commercial Real Estate Price Index. Both the SBA commercial real estate ACL model and the SBA commercial business model are adjusted for the national unemployment rate, CPI and Real GDP. Residential and commercial construction The construction ACL model is adjusted for forecasted changes in the housing price indices, the Case-Schiller Home Price Index, the national unemployment rate, CPI and Real GDP. Land and land development The land and land development ACL model is adjusted for forecasted changes in the housing price indices, the Case-Schiller Home Price Index, the national unemployment rate, CPI and Real GDP. Commercial business The commercial business ACL model is adjusted for changes in the national unemployment level, CPI and Real GDP. Consumer The ACL model for consumer loans is adjusted for forecasted changes in the housing price indices, the Case-Schiller Home Price Index, the national unemployment rate, CPI and Real GDP. Allowance for Credit Losses – Unfunded Commitments The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit. 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 their estimated lives consistent with the Company’s ACL methodology for loans. Collateral Dependent Loans Loans on nonaccrual status which management believes the likely source of repayment to be operation or sale of the collateral are considered collateral dependent. Factors considered by management in determining collateral dependency include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Individually evaluated loans are measured on a loan-by-loan basis by either the present value of expected future cash flows discounted at the loan’s effective interest rate, the loan’s obtainable market price, or the fair value of the collateral if the loan is collateral dependent. Values for collateral dependent loans are generally based on appraisals obtained from independent licensed real estate appraisers, with adjustments applied for estimated costs to sell the property, estimated costs to complete unfinished or repair damaged property, and other known defects. New appraisals are generally obtained for all significant properties when a loan is identified as collateral dependent. Generally, a property is considered significant if the value of the property is estimated to exceed $250,000. Subsequent appraisals are obtained as needed or if management believes there has been a significant change in the market value of a collateral property securing a collateral dependent loan. In instances where it is not deemed necessary to obtain a new appraisal, management would base its allowance for credit loss on the original appraisal with adjustments for current conditions based on management’s assessment of market factors and management’s inspection of the property. Financial Difficulty Modifications Financial difficulty modifications (FDMs) may result when a borrower is in financial distress, and may be in the form of principal forgiveness, an interest rate reduction, a term extension a payment delay that is other-than-insignificant or any combination thereof. The Company’s credit department evaluates modifications and identifies any FDMs on a quarterly basis. Allowance for Credit Losses – Held to Maturity (HTM) Securities The Company measures expected credit losses on HTM securities on a collective basis by major security type with each type sharing similar risk characteristics. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The Company has made the election to exclude accrued interest receivable on HTM securities from the estimate of credit losses and report accrued interest separately on the condensed consolidated balance sheets. See Note 2 – Investment Securities, for additional information related the Company’s allowance for credit losses on HTM securities. Allowance for Credit Losses – Available for Sale (AFS) Securities For AFS securities in an unrealized loss position, the Company first evaluates whether it intends to sell, or whether it is more likely than not that it will be required to sell, the security before recovery of its amortized cost basis, which may be at maturity. If either of these criteria regarding intent or requirement to sell is met, the AFS security amortized cost basis is written down to fair value through income. If the criteria is not met, the Company is required to assess whether the decline in fair value has resulted from credit related factors. If the assessment indicates 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. If the present value of cash flows expected to be collected is less than the amortized cost basis, a credit loss exists, and an allowance for credit loss is recorded through income as a component of provision for credit loss expense. If the assessment indicates that a credit loss does not exist, the Company records the decline in fair value through other comprehensive income, net of related income tax effects. The Company has made the election to exclude accrued interest receivable on AFS securities from the estimate of credit losses and report accrued interest separately on the condensed consolidated balance sheets. Changes in the allowance for credit losses are recorded as provision for (or reversal of) credit loss expense. Losses are charged against the allowance when management believes the uncollectibility of an AFS security is confirmed or when either of the criteria regarding intent or requirement to sell is met. See Note 2 – Investment Securities, for additional information related to the Company’s allowance for credit losses on AFS securities.

Investment Securities	2. Investment Securities U.S. agency bonds and notes, agency mortgage-backed securities and agency collateralized mortgage obligations (“CMO”) include treasury notes issued by the U.S. government; securities issued by the Government National Mortgage Association (“GNMA”), a U.S. government agency; and securities issued by the Federal National Mortgage Association (“FNMA”), the Federal Home Loan Mortgage Corporation (“FHLMC”) and the Federal Home Loan Bank (“FHLB”), which are U.S. government sponsored enterprises. The Company holds municipal bonds issued by municipal governments within the U.S. The Company also holds pass-through asset-backed securities guaranteed by the SBA representing participating interests in pools of long term debentures issued by state and local development companies certified by the SBA. Privately issued CMO and asset-backed securities (“ABS”) are complex securities issued by non-government special purpose entities that are collateralized by residential mortgage loans and residential home equity loans. The Company also holds subordinated debt of a regional financial institution. Investment securities have been classified as either available for sale or held to maturity according to management’s intent. At this time, the Company does not intend to sell, and it is not more likely than not that the Company will be required to sell, debt securities in an unrealized loss position prior to maturity or recovery of the recorded value. The Company recorded a $6,000 credit for credit losses on investment securities for the three-month period ended December 31, 2024. The Company recorded no provision for credit losses on investment securities for the three-month period ended December 31, 2023. The Company’s held to maturity (“HTM”) debt securities consist of two agency mortgage-backed securities and two municipal bonds. The agency mortgage-backed securities carry an explicit and/or implicit guarantee of the U.S. government, are widely considered as “risk free” and have a long history of zero credit loss. The two HTM municipal bonds are unrated, but have performed as agreed and are not considered to be credit impaired. The carrying value of HTM debt securities totaled $1.0 million at December 31, 2024. There were no HTM securities on nonaccrual status or past due as of December 31, 2024 Debt Securities Available for Sale and Held to Maturity The following tables provide a summary of debt securities available for sale and held to maturity: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Gross ​ Allowance ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ for Credit ​ Fair ​ Cost Gain Losses Losses Value ​ ​ (In thousands) December 31, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debt securities available for sale: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury notes ​ $ 29,761 ​ $ — ​ $ 3,883 ​ $ — ​ $ 25,878 Agency mortgage-backed ​ ​ 27,805 ​ ​ 1 ​ ​ 3,436 ​ ​ — ​ ​ 24,370 Agency CMO ​ 16,420 ​ — ​ 1,072 ​ ​ — ​ 15,348 Privately-issued CMO ​ 280 ​ 3 ​ 17 ​ ​ 15 ​ 251 Privately-issued ABS ​ 273 ​ 9 ​ — ​ ​ — ​ 282 SBA certificates ​ 11,919 ​ — ​ 380 ​ ​ — ​ 11,539 Municipal bonds ​ 175,707 ​ 267 ​ 13,942 ​ ​ — ​ 162,032 Other ​ ​ 2,000 ​ ​ — ​ ​ 70 ​ ​ — ​ ​ 1,930 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total debt securities available for sale ​ $ 264,165 ​ $ 280 ​ $ 22,800 ​ $ 15 ​ $ 241,630 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debt securities held to maturity: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Agency mortgage-backed ​ $ 28 ​ $ — ​ $ — ​ $ — ​ $ 28 Municipal bonds ​ 976 ​ 7 ​ — ​ ​ — ​ 983 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total debt securities held to maturity ​ $ 1,004 ​ $ 7 ​ $ — ​ $ — ​ $ 1,011 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Gross Gross Allowance ​ ​ ​ ​ Amortized ​ Unrealized ​ Unrealized ​ for Credit ​ Fair ​ Cost Gain Losses ​ Losses ​ Value ​ ​ (In thousands) ​ ​ ​ September 30, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debt securities available for sale: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ U.S. Treasury notes ​ $ 30,031 ​ $ — ​ $ 2,620 ​ $ — ​ $ 27,411 Agency mortgage-backed ​ ​ 28,425 ​ ​ 8 ​ ​ 2,157 ​ ​ — ​ ​ 26,276 Agency CMO ​ ​ 15,700 ​ ​ — ​ ​ 774 ​ ​ — ​ ​ 14,926 Privately-issued CMO ​ 295 ​ 2 ​ 16 ​ 21 ​ ​ 260 Privately-issued ABS ​ 301 ​ 12 ​ — ​ — ​ ​ 313 SBA certificates ​ 11,993 ​ — ​ 67 ​ — ​ ​ 11,926 Municipal bonds ​ 174,132 ​ 1,048 ​ 9,493 ​ — ​ ​ 165,687 Other ​ ​ 2,000 ​ ​ — ​ ​ 120 ​ ​ — ​ ​ 1,880 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total debt securities available for sale ​ $ 262,877 ​ $ 1,070 ​ $ 15,247 ​ $ 21 ​ $ 248,679 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Debt securities held to maturity: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Agency mortgage-backed ​ $ 29 ​ $ — ​ $ — ​ $ — ​ $ 29 Municipal bonds ​ 1,011 ​ 12 ​ — ​ — ​ 1,023 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total debt securities held to maturity ​ $ 1,040 ​ $ 12 ​ $ — ​ $ — ​ $ 1,052 ​ The amortized cost and fair value of investment securities as of December 31, 2024 by contractual maturity are shown below.

All debt securities available for sale with unrealized losses are reviewed quarterly. For debt securities available for sale in an unrealized loss position, the Company first assesses whether it intends to sell or it is more likely than not that it will be required to sell the security before recovery of its amortized cost basis, which may be at maturity. If either of the criteria regarding intent or requirement to sell is met, the security’s amortized cost basis is written down to fair value through the income statement. For debt securities available for sale in an unrealized loss position that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from credit deterioration or other factors. In making this assessment, management considers the extent to which fair value is less than amortized cost, any changes to the rating of the security by a rating agency and adverse conditions specifically related to the security, among other factors. 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. If the present value of cash flows expected to be collected is less than the amortized cost basis for the security, a credit loss exists and an allowance for credit losses is recorded, limited to the amount that the fair value of the security is less than its amortized cost basis. The total debt securities available for sale in loss positions at December 31, 2024, which consisted of U.S. Treasury notes, agency mortgage-backed securities, agency CMOs, privately-issued CMOs, municipal bonds, SBA certificates and other securities represented 90% of total debt securities available for sale at December 31, 2024. All of the municipal securities are issued by municipal governments and are generally secured by first mortgage loans and municipal project revenues. The Company evaluates the existence of a potential credit loss component related to the decline in fair value of the privately issued CMO and ABS portfolios each quarter using an independent third party analysis. At December 31, 2024, the Company held three privately-issued CMO and ABS securities, acquired in a 2009 bank merger, with an aggregate amortized cost of $321,000 and fair value of $308,000 that have been downgraded to a substandard regulatory classification due to the securities credit quality rating by various rating agencies. At December 31, 2024, two privately-issued CMO securities and one privately-issued ABS were in a loss position, and had depreciated approximately 5.1% from the Company’s carrying value and were collateralized by residential mortgage loans. These securities had a total fair value of $324,000 and a total unrealized loss of $17,000 at December 31, 2024. Based on the independent third party analysis of the expected cash flows, no credit loss was recognized during the three months ended December 31, 2024 and 2023. A total of two securities had credit losses totaling $15,000 as of December 31, 2024. While the Company does not anticipate additional credit-related impairment losses at December 31, 2024, additional deterioration in market and economic conditions may have an adverse impact on the credit quality of the portfolio, and therefore, require a credit related impairment charge in the future. The unrealized losses on U.S. Treasury bills and notes, agency mortgage-backed securities, agency CMOs, SBA certificates and municipal bonds relate principally to changes in current interest rates for similar types of securities. In analyzing an issuer’s financial condition, management considers whether the securities are issued by the federal government, its agencies, or other governments, whether downgrades by bond rating agencies have occurred, and the results of reviews of the issuer’s financial condition. Because the Company does not intend to sell the investments and it is not more likely than not the Company will be required to sell the investments before recovery of its amortized cost bases, which may be at maturity, the Company has not recorded an allowance for credit losses at December 31, 2024. During the three-month periods ended December 31, 2024 and 2023, there were no sales of debt securities available for sale. At December 31, 2024 and September 30, 2024, available for sale debt securities with a total fair value of $51.2 million and $54.2 million, respectively, were pledged to secure FHLB borrowings. At December 31, 2024 and September 30, 2024, available for sale debt securities with a total fair value of $60.7 million and $62.8 million, respectively, were pledged to secure Federal Reserve Discount Window borrowings.

extension or a significant payment delay. In some cases, the Company may provide multiple types of modifications for a single loan. One type of modification, such as payment delay, may be granted initially. However, if the borrower continues to experience financial difficulty, another modification, such as term extension and/or interest rate reduction may be granted. Additionally, modifications with a term extension or interest rate reduction are intended to reduce the borrower’s monthly payment, while modifications with a payment delay, which typically allow borrowers to make monthly payments or interest only payments for a period of time, are structured to cure the payment defaults by making delinquent payments due at maturity. There were no new FDMs made or modifications of existing FDMs during the three months ended December 31, 2024 and 2023. SBA Loan Servicing Rights The Company originates loans to commercial customers under the SBA 7(a) program and other programs, and typically sells the guaranteed portion of the SBA loans with servicing rights retained. Loan servicing rights on originated SBA loans that have been sold are initially recorded at fair value. Capitalized SBA servicing rights are then amortized in proportion to and over the period of estimated net servicing income. Impairment of SBA servicing rights is assessed using the present value of estimated future cash flows. The aggregate fair value of SBA loan servicing rights approximates its carrying value. A valuation model employed by an independent third party calculates the present value of future cash flows and is used to estimate fair value at the date of sale and on a quarterly basis for impairment analysis purposes. Management periodically compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. Key assumptions used to estimate the fair value of the SBA loan servicing rights include the discount rate and prepayment speed assumptions. For purposes of impairment, risk characteristics such as interest rate, loan type, term and investor type are used to stratify the SBA loan servicing rights. Impairment is recognized through a valuation allowance to the extent that fair value is less than the carrying amount. Changes in the valuation allowance are reported in other noninterest income in the consolidated statements of income. The unpaid principal balance of SBA loans serviced for others was $193.9 million, $194.4 million and $211.3 million at December 31, 2024, September 30, 2024 and December 31, 2023, respectively. Contractually specified late fees and ancillary fees expensed on SBA loans were $11,000 for the three-month period ended December 31, 2024 compared to a credit of $9,000 for the three-month period ended December 31, 2023. Net servicing income (contractually specified servicing fees offset by direct servicing expenses) related to SBA loans was $430,000 and $464,000 for the three-month periods ended December 31, 2024 and 2023, respectively. Net servicing income and costs related to SBA loans are included in other noninterest income in the consolidated statements of income. ​ An analysis of SBA loan servicing rights for the three-month periods ended December 31, 2024 and 2023 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2024 2023 ​ ​ (In thousands) ​ ​ ​ Balance, beginning of period ​ $ 2,687 ​ $ 2,950 Servicing rights capitalized ​ 202 ​ 257 Amortization ​ (133) ​ (143) Direct write-offs ​ ​ (162) ​ ​ (217) Change in valuation allowance ​ 5 ​ 60 Balance, end of period ​ $ 2,599 ​ $ 2,907 ​ There was no valuation allowance related to SBA loan servicing rights at December 31, 2024. There was a valuation allowance of $5,000 related to SBA loan servicing rights at September 30, 2024. Mortgage Servicing Rights (“MSRs”) The Company originated residential mortgage loans for sale in the secondary market and retained servicing for certain of these loans when they were sold. MSRs retained for originated loans that have been sold are accounted for at fair value. The fair value of MSRs are determined using the present value of estimated expected net servicing income using assumptions about expected mortgage loan prepayment rates, discount rate, servicing costs, and other economic factors, which are determined based on current market conditions. Changes in these underlying assumptions could cause the fair value of MSRs to change significantly in the future. Changes in fair value of MSRs are recorded in mortgage banking income in the accompanying consolidated statements of income. MSRs are subject to changes in value from, among other things, changes in interest rates, prepayments of the underlying loans and changes in the credit quality of the underlying loans. During the quarter ended December 31, 2023, the Company sold substantially all of the Company’s residential MSRs. Additionally, the Company sold the remaining residential MSRs during the quarter ended March 31, 2024. There was no unpaid principal balance of residential mortgage loans serviced for others at December 31, 2024 and September 30, 2024 due to the sale of all of the Company’s residential MSRs during the six-month period ended March 31, 2024, which also resulted in the elimination of custodial escrow balances. There were no custodial escrow balances maintained in connection with loan servicing and other liabilities at December 31, 2024. ​ Changes in the carrying value of MSRs accounted for at fair value for the three-month period ended December 31, 2023 were as follows: ​ ​ ​ ​ ​ ​ 2023 ​ ​ (In thousands) Fair value, beginning of period ​ $ 59,768 Servicing rights capitalized ​ ​ 509 Changes in fair value related to: ​ ​ ​ Loan repayments ​ ​ (666) Sales ​ ​ (58,765) Change in valuation model inputs or assumptions ​ ​ (137) Balance, end of period ​ $ 709 ​ Nonresidential MSRs The Company also periodically sells single tenant net lease loans with servicing rights retained. Loan servicing rights on these nonresidential mortgage loans are initially recorded at fair value and are then amortized in proportion to and over the period of estimated net servicing income. Impairment of nonresidential MSRs is assessed using the present value of estimated future cash flows. The aggregate fair value of nonresidential MSRs approximates its carrying value. A valuation model employed by management calculates the present value of future cash flows and is used to estimate fair value at the date of sale and on a quarterly basis for impairment analysis purposes. Management periodically compares the valuation model inputs and results to published industry data in order to validate the model results and assumptions. Key assumptions used to estimate the fair value of the nonresidential MSRs include the discount rate and prepayment speed assumptions. Impairment is recognized through a valuation allowance to the extent that fair value is less than the carrying amount. Changes in the valuation allowance are reported in other noninterest income in the consolidated statements of income. The unpaid principal balance of nonresidential mortgage loans serviced for others was $34.8 million, $35.0 million and $40.3 million at December 31, 2024, September 30, 2024 and December 31, 2023, respectively. Contractually specified servicing fees, late fees and other ancillary fees related to nonresidential mortgage loans serviced for others were $2,000 and $4,000 for the three-month periods ended December 31, 2024 and 2023, respectively. Contractually specified servicing fees on nonresidential mortgage loans serviced for others are included in other noninterest income in the consolidated statements of income. ​ An analysis of nonresidential MSRs for the three-month periods ended December 31, 2024 and 2023 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ 2024 2023 ​ ​ (In thousands) Balance, beginning of period ​ $ 67 ​ $ 101 Servicing rights capitalized ​ — ​ — Amortization ​ (5) ​ (6) Direct write-offs ​ — ​ — Change in valuation allowance ​ — ​ ​ — Balance, end of period ​ $ 62 ​ $ 95 ​ There was no valuation allowance related to nonresidential MSRs at December 31, 2024 and September 30, 2024.

Fair Value Measurements and Disclosures about Fair Value of Financial Instruments	6. Fair Value Measurements and Disclosures about Fair Value of Financial Instruments FASB Accounting Standards Codification (“ASC”) Topic 820 , Fair Value Measurements, Level 1: Inputs to the valuation methodology are quoted prices, unadjusted, for identical assets or liabilities in active markets. A quoted market price in an active market provides the most reliable evidence of fair value and shall be used to measure fair value whenever available. Level 2: Inputs to the valuation methodology include quoted market prices for similar assets or liabilities in active markets; quoted market prices for identical or similar assets or liabilities in markets that are not active; or inputs that are derived principally from or can be corroborated by observable market data by correlation or other means. Level 3: Inputs to the valuation methodology are unobservable and significant to the fair value measurement. Level 3 assets and liabilities include financial instruments whose value is determined using discounted cash flow methodologies, as well as instruments for which the determination of fair value requires significant management judgment or estimation. A description of the valuation methodologies used for instruments measured at fair value, as well as the general classification of such instruments pursuant to the valuation hierarchy, is set forth below. The tables below present the balances of financial assets and liabilities measured at fair value on a recurring and nonrecurring basis as of December 31, 2024 and September 30, 2024. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying Value ​ Level 1 Level 2 Level 3 Total ​ ​ (In thousands) December 31, 2024: ​ ​ ​ ​ Assets Measured – Recurring Basis: ​ ​ ​ ​ Securities available for sale: ​ ​ ​ ​ U.S. Treasury bills and notes ​ $ 25,878 ​ $ — ​ $ — ​ $ 25,878 Agency mortgage-backed ​ ​ — ​ ​ 24,370 ​ ​ — ​ ​ 24,370 Agency CMO ​ — ​ 15,348 ​ — ​ 15,348 Privately-issued CMO ​ — ​ 20 ​ 231 ​ 251 Privately-issued ABS ​ — ​ 204 ​ 78 ​ 282 SBA certificates ​ — ​ 11,508 ​ 31 ​ 11,539 Municipal bonds ​ — ​ 162,032 ​ — ​ 162,032 Other ​ ​ — ​ ​ — ​ ​ 1,930 ​ ​ 1,930 Total securities available for sale ​ $ 25,878 ​ $ 213,482 ​ $ 2,270 ​ $ 241,630 Equity securities (included in other assets) ​ $ 204 ​ $ 525 ​ $ — ​ $ 729 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets Measured – Nonrecurring Basis: ​ ​ ​ ​ Collateral dependent loans: ​ ​ ​ ​ Residential real estate ​ $ — ​ $ — ​ $ 1,579 ​ $ 1,579 SBA commercial real estate ​ ​ — ​ ​ — ​ ​ 1,156 ​ ​ 1,156 Commercial business ​ ​ — ​ ​ — ​ ​ 675 ​ ​ 675 SBA commercial business ​ — ​ — ​ 951 ​ 951 Consumer ​ ​ — ​ ​ — ​ ​ 4 ​ ​ 4 Total collateral dependent loans ​ $ — ​ $ — ​ $ 4,365 ​ $ 4,365 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Carrying Value ​ Level 1 Level 2 Level 3 Total ​ ​ (In thousands) September 30, 2024: ​ ​ ​ ​ ​ ​ ​ ​ Assets Measured – Recurring Basis ​ ​ ​ ​ Securities available for sale: ​ ​ ​ ​ U.S. Treasury notes ​ $ 27,411 ​ $ — ​ $ — ​ $ 27,411 Agency mortgage-backed ​ ​ — ​ ​ 26,276 ​ ​ — ​ ​ 26,276 Agency CMO ​ — ​ 14,926 ​ — ​ 14,926 Privately-issued CMO ​ — ​ 20 ​ 240 ​ 260 Privately-issued ABS ​ — ​ 235 ​ 78 ​ 313 SBA certificates ​ — ​ 11,896 ​ 30 ​ 11,926 Municipal bonds ​ — ​ 165,687 ​ — ​ 165,687 Other ​ ​ — ​ ​ — ​ ​ 1,880 ​ ​ 1,880 Total securities available for sale ​ $ 27,411 ​ $ 219,040 ​ $ 2,228 ​ $ 248,679 Equity securities (included in other assets) ​ $ 194 ​ $ 456 ​ $ — ​ $ 650 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Assets Measured – Nonrecurring Basis ​ ​ ​ ​ Collateral dependent loans: ​ ​ ​ ​ Residential real estate ​ $ — ​ $ — ​ $ 1,100 ​ $ 1,100 Commercial real estate ​ ​ — ​ ​ — ​ ​ 120 ​ ​ 120 SBA real estate ​ ​ — ​ ​ — ​ ​ 1,763 ​ ​ 1,763 Commercial business ​ — ​ — ​ 768 ​ 768 SBA commercial business ​ ​ — ​ ​ — ​ ​ 1,183 ​ ​ 1,183 Consumer ​ ​ — ​ ​ — ​ ​ 4 ​ ​ 4 Total collateral dependent loans ​ $ — ​ $ — ​ $ 4,938 ​ $ 4,938 SBA loan servicing rights ​ $ — ​ $ — ​ $ 2,687 ​ $ 2,687 ​ Fair value is based upon quoted market prices where available. If quoted market prices are not available, fair value is based on internally developed models or obtained from third parties that primarily use, as inputs, observable market-based parameters or a matrix pricing model that employs the Bond Market Association’s standard calculations for cash flow and price/yield analysis and observable market-based parameters. Valuation adjustments may be made to ensure that financial instruments are recorded at fair value, or at the lower of cost or fair value. These adjustments may include unobservable parameters. Any such valuation adjustments have been applied consistently over time. The Company’s valuation methodologies may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. While management believes the Company’s valuation methodologies are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different estimate of fair value at the reporting date. There have been no changes in the valuation techniques and related inputs used for assets measured at fair value on a recurring and nonrecurring basis during the three-month period ended December 31, 2024. Debt Securities Available for Sale and Equity Securities. Derivative Financial Instruments The fair value of interest rate lock commitments is also obtained from an independent third party and is based on investor prices for the underlying loans or current secondary market prices for loans with similar characteristics, less estimated costs to originate the loans and adjusted for the anticipated funding probability (pull-through rate). The fair value of interest rate lock commitments is classified as Level 3 in the fair value hierarchy. Due to the wind down of the Company’s national Mortgage Banking operation, and the resulting low level of mortgage loan originations and sales, there were no interest rate lock commitments or forward mortgage loan sale commitments as of December 31, 2024. The table below presents a reconciliation of derivative assets and liabilities (interest rate lock commitments) measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three-month periods ended December 31, 2024 and 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ December 31, (In thousands) 2024 2023 ​ ​ ​ ​ ​ ​ ​ Beginning balance ​ $ — ​ $ 268 Unrealized gains (losses) recognized in earnings, net of settlements ​ — ​ (268) ​ ​ ​ ​ ​ ​ ​ Ending balance ​ $ — ​ $ — ​ The realized and unrealized gains recognized in earnings in the table above are included in mortgage banking income on the accompanying consolidated statements of income. There were no unrealized gains recognized in earnings for the three-month periods ended December 31, 2024 and 2023 attributable to Level 3 derivative assets and liabilities held at the balance sheet date. There were no interest rate lock commitments as of December 31, 2024. ​ Collateral Dependent Loans Collateral may be real estate and/or business assets, including equipment, inventory and/or accounts receivable, and its fair value is generally determined based on real estate appraisals or other independent evaluations by qualified professionals. The appraisals are then discounted to reflect management’s estimate of the fair value of the collateral given the current market conditions and the condition of the collateral. At December 31, 2024 and September 30, 2024, the significant unobservable inputs used in the fair value measurement of collateral dependent loans were as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Range of Inputs ​ ​ ​ Significant ​ (Weighted Average) ​ Range of Inputs (Weighted ​ ​ Unobservable ​ December 31, ​ Average) September 30, Financial Instrument ​ Inputs ​ 2024 ​ 2024 Collateral dependent loans Discount from appraised value 0.0% - 100.0% (16.43%) 0.0% - 100.0% (18.42%) ​ Estimated costs to sell 9.0% - 9.0% (9.00%) 6.0% - 6.0% (6.00%) ​ During the three-month periods ended December 31, 2024 and 2023, the Company recognized provisions for credit losses on individually evaluated loans of $437,000 and $691,000, respectively.

The Company reversed impairment charges of $5,000 and $60,000 on SBA loan servicing rights for the three-month periods ended December 31, 2024 and 2023, respectively. There were no transfers into or out of the Company’s Level 3 financial assets of the fair value hierarchy for the three-month period ended December 31, 2024. At December 31, 2024. the Company had one available for sale other investment security (subordinated debt in another financial institution) in Level 3 in the fair value hierarchy.

Financial Instruments Recorded Using Fair Value Option. Prior to the winddown of the Company’s national mortgage banking operation, the Company had elected the fair value option for a portion of its residential mortgage loans held for sale. However, at December 31, 2024, there were no mortgage loans held for sale carried at fair value. The Company had no residential mortgage loans held for sale as of September 30, 2024. The table below presents gains and losses and interest included in earnings related to financial assets measured at fair value under the fair value option for the three-month periods ended December 31, 2024 and 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ December 31, (In thousands) 2024 2023 ​ ​ ​ ​ ​ ​ ​ Gains (losses) – included in mortgage banking income ​ $ — ​ $ (1,029) Interest income ​ — ​ 293 ​ ​ ​ ​ ​ ​ ​ ​ ​ $ — ​ $ (736) ​ GAAP requires disclosure of fair value information about financial instruments for interim reporting periods, whether or not recognized in the consolidated balance sheet. In cases where quoted market prices are not available, fair values are based on estimates using present value or other valuation techniques. Those techniques are significantly affected by the assumptions used, including the discount rate and estimates of future cash flows. In that regard, the derived fair value estimates cannot be substantiated by comparison to independent markets and, in many cases, could not be realized in immediate settlement of the instruments. Accordingly, the aggregate fair value amounts presented do not represent the underlying value of the Company.

Employee Stock Ownership Plan	7. Employee Stock Ownership Plan On October 6, 2008, the Company established a leveraged employee stock ownership plan (“ESOP”) covering substantially all employees. The ESOP trust acquired 610,089 shares of Company common stock at a cost of $3.33 per share (both as adjusted for the three-for-one stock split effective September 15, 2021) financed by a term loan with the Company. The ESOP loan was repaid in full during the quarter ended December 31, 2015 and all shares have been allocated to participants in the plan; therefore, no compensation expense was recognized for the three-month periods ended December 31, 2024 and 2023. The ESOP trust held 263,667 and 262,176 shares of Company common stock at December 31, 2024 and September 30, 2024, respectively.

Stock Based Compensation Plans
Stock Based Compensation Plans	8. Stock Based Compensation Plans The Company maintains three equity incentive plans under which stock options and restricted stock have been or may be granted, the 2010 Equity Incentive Plan (“2010 Plan”), approved by the Company’s shareholders in February 2010, the 2016 Equity Incentive Plan (“2016 Plan”), approved by the Company’s shareholders in February 2016, and the 2021 Equity Incentive Plan (“2021 Plan”) approved by the Company’s shareholders in February 2021. At December 31, 2024, there were no remaining shares of the Company’s common stock available for issuance under the 2010 Plan or the 2021 Plan. The aggregate number of shares of the Company’s common stock available for issuance under the 2016 Plan may not exceed 264,000 shares, consisting of 198,000 stock options and 66,000 shares of restricted stock. At December 31, 2024, 2,700 shares of the Company’s common stock were available for issuance under the 2016 Plan, all of which were available for stock options. In November 2024, the Company granted 21,075 stock options and 6,090 restricted shares to directors, officers and key employees which will vest over a one-year or five-year period. The Company generally issues new shares under 2016 and 2021 Plans from its authorized but unissued shares. The Company accounts for any forfeitures as they occur, and any previously recognized compensation cost for an award is reversed in the period the award is forfeited. Stock Options Under the plans, the Company may grant both non-statutory and incentive stock options that may not have a term exceeding ten years. In the case of incentive stock options, the aggregate fair value (determined at the time the incentive stock options are granted) which are first exercisable during any calendar year shall not exceed $100,000. Exercise prices may not be less than the fair market value of the underlying stock at the date of the grant. The terms of the plans also include provisions whereby all unearned options and restricted shares become immediately exercisable and fully vested upon a change in control. Stock options granted generally vest ratably over five years and are exercisable in whole or in part for a period up to ten years from the date of the grant. Compensation expense is measured based on the fair market value of the options at the grant date and is recognized ratably over the period during which the shares are earned (the vesting period). The fair market value of stock options granted is estimated at the date of grant using a binomial option pricing model. Expected volatilities are based on historical volatility of the Company’s stock. The expected term of options granted represents the period of time that options are expected to be outstanding. The risk free rate for the expected life of the options is based on the U.S. Treasury yield curve in effect at the grant date. The fair value of options granted during the three-month periods ended December 31, 2024 and 2023 were determined using the following assumptions: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ 2024 2023 ​ Expected dividend yield ​ ​ 2.55 % ​ 3.74 % Risk-free interest rate ​ 4.36 % ​ 4.44 % Expected volatility ​ 29.70 % ​ 28.36 % Expected life of options ​ 6.9 years ​ ​ 6.9 years ​ Weighted average fair value at grant date ​ $ 8.44 ​ $ 3.55 ​ ​ A summary of stock option activity as of December 31, 2024, and changes during the three-month period then ended is presented below. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ ​ ​ ​ ​ ​ ​ ​ Average ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Remaining ​ ​ ​ ​ ​ ​ ​ Weighted ​ Contractual ​ Aggregate ​ ​ Number of ​ Average ​ Term ​ Intrinsic ​ ​ Shares ​ Exercise Price ​ (Years) ​ Value ​ ​ (Dollars in thousands, except exercise price data) ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Outstanding at beginning of period 459,547 ​ $ 20.09 ​ ​ ​ ​ ​ Granted 21,075 ​ ​ 29.00 ​ ​ ​ Exercised (26,907) ​ 16.15 ​ ​ ​ Forfeited or expired — ​ — ​ ​ ​ Outstanding at end of period 453,715 ​ $ 19.39 4.2 ​ $ 2,010 Exercisable at end of period 297,971 ​ $ 20.16 4.8 ​ $ 1,922 ​ There were 26,907 stock options exercised during the three-month period ended December 31, 2024. There were no stock options exercised during the three-month period ended December 31, 2023. The Company recognized compensation expense related to stock options of $84,000 and $75,000 for the three-month periods ended December 31, 2024 and 2023, respectively. At December 31, 2024, there was $803,000 of unrecognized compensation expense related to nonvested stock options. The compensation expense is expected to be recognized over a weighted average period of 3.11 years. There was $396,000 in cash received and $26,000 in tax benefit from the exercise of stock options during the three-month period ended December 31, 2024. There was no cash received and no tax benefit from exercise during the three-month period ended December 31, 2023 due to no options being exercised during the period. Restricted Stock The vesting period of restricted stock granted under the plans is generally five years beginning one year after the date of grant of the awards. Compensation expense is measured based on the fair market value of the restricted stock at the grant date and is recognized ratably over the vesting period. Compensation expense related to restricted stock recognized for the three-month periods ended December 31, 2024 and 2023 was $105,000 and $97,000, respectively. A summary of the Company’s nonvested restricted shares activity as of December 31, 2024 and changes during the three-month period then ended is presented below. ​ ​ ​ ​ ​ ​ ​ ​ ​ Weighted ​ ​ Number ​ Average ​ ​ of ​ Grant Date ​ ​ Shares ​ Fair Value Nonvested at October 1, 2024 57,433 ​ $ 21.64 Granted 6,090 ​ $ 29.00 Vested (17,903) ​ $ 21.80 Forfeited — ​ ​ — Nonvested at December 31, 2024 45,620 ​ $ 22.55 ​ There were 17,903 restricted shares vested during the three-month period ended December 31, 2024 with a total fair value of $244,000.

Derivative Financial Instruments
Derivative Financial Instruments	9. Derivative Financial Instruments Prior to the winddown of the Company’s national mortgage banking division, the Company entered into commitments to originate loans whereby the interest rate on the loan is determined prior to funding (i.e., rate lock commitment). The Company also entered into forward mortgage loan commitments to sell loans to various investors to protect itself against exposure to various factors and to reduce sensitivity to interest rate movements. Both the interest rate lock commitments and the related forward mortgage loan sales contracts are considered derivatives and are recorded on the accompanying consolidated balance sheets at fair value in accordance with FASB ASC 815, Derivatives and Hedging Certain financial instruments, including derivatives, may be eligible for offset in the balance sheet when the “right of setoff” exists or when the instruments are subject to an enforceable master netting agreement, which includes the right of the non-defaulting party or non-affected party to offset recognized amounts, including collateral posted with the counterparty, to determine a net receivable or net payable upon early termination of the agreement. Certain of the Company’s derivative instruments are subject to master netting agreements. However, the Company has not elected to offset such financial instruments in the consolidated balance sheets. The Company may be required to post margin collateral to derivative counterparties based on agreements with the dealers. Cash collateral related to derivative contracts is recorded in interest-bearing deposits with banks or other assets in the consolidated balance sheets. At December 31, 2024 and September 30, 2024, the Company had no cash collateral posted with derivative counterparties against its derivative obligations. As of December 31, 2024 and September 30, 2024, the Company had no derivative financial instruments due to the wind down of the national mortgage banking operation. ​ Income (loss) related to derivative financial instruments included in mortgage banking income in the accompanying consolidated statements of income for the three-month periods ended December 31, 2024 and 2023 is as follows: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Three Months Ended ​ ​ December 31, (In thousands) 2024 2023 ​ ​ ​ ​ ​ ​ ​ Interest rate lock commitments ​ $ — ​ $ (268) Forward mortgage loan sale contracts ​ — ​ 354 ​ ​ ​ ​ ​ ​ ​ ​ ​ $ — ​ $ 86 ​

Regulatory Capital

Regulatory Capital
Regulatory Capital	10. Regulatory Capital The Bank is subject to various regulatory capital requirements administered by the federal banking agencies. Failure to meet minimum capital requirements can initiate certain mandatory and possibly additional discretionary actions by regulators that, if undertaken, could have a direct material effect on the Company’s consolidated financial statements. Under capital adequacy guidelines and the regulatory framework for prompt corrective action, the Bank must meet specific capital guidelines that involve quantitative measures of the Bank’s assets, liabilities, and certain off-balance-sheet items as calculated under regulatory accounting practices. The 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 (set forth in the table below) of total, Tier 1 and common equity Tier 1 capital (as defined in the regulations) to risk-weighted assets (as defined), and Tier 1 capital (as defined) to average assets (as defined). The final rules implementing the Basel Committee on Banking Supervision’s capital guidelines for U.S. banks (“Basel III rules”) became effective for the Bank on January 1, 2015, with full compliance with all of the requirements being phased in over a multi-year schedule through 2019. Under the Basel III rules, the Bank must hold a conservation buffer above the adequately capitalized risk-based capital ratios disclosed in the table below. The capital conservation buffer was 2.50% for 2024 and 2023. The Bank met all capital adequacy requirements to which it was subject as of December 31, 2024 and September 30, 2024. As of December 31, 2024, the most recent notification from the Federal Reserve Bank 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 total risk-based, Tier 1 risk-based, common equity Tier 1 risk-based and Tier 1 leverage ratios as set forth in the table below. There are no conditions or events since that notification that management believes have changed the Bank’s category. The Company’s and Bank’s actual capital amounts and ratios are also presented in the table. The Company is not subject to the Federal Reserve Bank’s consolidated capital requirements because it has less than $3 billion in total consolidated assets. However, management has elected to disclose the Company’s capital amounts and ratios in addition to the Bank’s required disclosures in the table below. No amount was deducted from capital for interest-rate risk at either date. ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Minimum To Be Well ​ ​ ​ ​ ​ ​ ​ Minimum ​ Capitalized Under ​ ​ ​ ​ ​ ​ ​ For Capital ​ Prompt Corrective ​ ​ Actual ​ Adequacy Purposes: ​ Action Provisions: ​ Amount Ratio Amount Ratio Amount Ratio ​ ​ (Dollars in thousands) ​ As of December 31, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital (to risk-weighted assets): ​ ​ ​ ​ Consolidated ​ $ 245,524 12.83 % $ 153,138 8.00 % ​ N/A N/A ​ Bank ​ 248,937 13.01 ​ 153,094 8.00 ​ $ 191,367 10.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 184,317 9.63 % $ 114,854 6.00 % N/A N/A ​ Bank ​ 228,372 11.93 ​ 114,820 6.00 ​ $ 153,094 8.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common equity tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 184,317 9.63 % $ 86,140 4.50 % N/A N/A ​ Bank ​ 228,372 11.93 ​ 86,115 4.50 ​ $ 124,389 6.50 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 capital (to average adjusted total assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 184,317 7.53 % $ 97,904 4.00 % N/A N/A ​ Bank ​ 228,372 9.33 ​ 97,889 4.00 ​ $ 122,361 5.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ As of September 30, 2024: ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Total capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 244,214 12.53 % $ 155,976 8.00 % ​ N/A N/A ​ Bank ​ 242,041 12.42 ​ 155,946 8.00 ​ $ 194,932 10.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 179,325 9.20 % $ 116,982 6.00 % N/A N/A ​ Bank ​ 221,755 11.38 ​ 116,959 6.00 ​ $ 155,946 8.00 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Common equity tier 1 capital (to risk-weighted assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 179,325 9.20 % $ 87,737 4.50 % N/A N/A ​ Bank ​ 221,755 11.38 ​ 87,720 4.50 ​ $ 126,706 6.50 % ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Tier 1 capital (to average adjusted total assets): ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Consolidated ​ $ 179,325 7.42 % $ 96,607 4.00 % N/A N/A ​ Bank ​ 221,755 9.18 ​ 96,590 4.00 ​ $ 120,737 5.00 % ​

Recent Accounting Pronouncements	11. Recent Accounting Pronouncements The following are summaries of recently issued or adopted accounting pronouncements that impact the accounting and reporting practices of the Company: In June 2022, the FASB issued ASU No. 2022-03, Fair Value Measurements (Topic 820), Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions . The ASU clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. It also clarifies that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. For public business entities, the ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted and the amendments in the ASU should be applied prospectively with any adjustments from the adoption of the amendments recognized in earnings and disclosed on the date of adoption. The adoption of the ASU did not have a material impact on the Company’s consolidated financial position or results of operations. 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 allows an entity to elect to use the proportional amortization method to account for qualifying equity investments in tax credit structures that meet specified criteria, without regard to the underlying tax credit program. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Company invested in a partnership that generates low-income housing tax credits and has accounted for this under proportional amortization with investment amortization expense recorded as a component of income tax expense. The Company’s early adoption of this ASU effective October 1, 2023 did not result in any one-time cumulative-effect adjustment to retained earnings, have a material impact on the Company’s consolidated financial position or results of operations, or impact prior periods. In November 2023, the FASB issued ASU 2023-07, Segment Reporting: Improvements to Reportable Segment Disclosures, which requires public entities to disclose information about their reportable segments’ significant expenses on an interim and annual basis. Public entities are required to disclose significant expense categories and amounts for each reportable segment. Significant expense categories are derived from expenses that are regularly reported to an entity’s chief operating decision-maker (“CODM”), and included in a segment’s reported measures of profit or loss. Public entities are also required to disclose the title and position of the CODM and explain how the CODM uses the reported measures of profit or loss to assess segment performance. The ASU requires interim disclosures of certain segment-related disclosures that previously were only required annually. The ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted and the ASU should be applied prospectively. The adoption of the ASU is not expected to have a material impact on the Company’s consolidated financial position or results of operations. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures The Company has determined that all other recently issued accounting pronouncements will not have a material impact on the Company’s consolidated financial statements or do not apply to its operations.

Segment Reporting
Segment Reporting	12. Segment Reporting The Company’s operations include two primary segments: core banking and SBA lending. Prior to September 30, 2023, the Company also operated a mortgage banking segment. However, the mortgage banking segment was wound down during the quarter ended December 31, 2023. The core banking segment originates residential, commercial and consumer loans and attracts deposits from its customer base. Net interest income from loans and investments that are funded by deposits and borrowings is the primary revenue for the core banking segment. The SBA lending segment originates loans guaranteed by the SBA, subsequently selling the guaranteed portion to outside investors. Net gains on sales of loans, net servicing income and net interest income are the primary sources of revenue for the SBA lending segment. The mortgage banking segment originated residential mortgage loans and sold them in the secondary market. Net gains on the sales of loans, net servicing income, income from derivative financial instruments and net interest income were the primary sources of revenue for the mortgage banking segment. The core banking segment is comprised primarily by the Bank and First Savings Investments, Inc., while the SBA lending segment’s revenues are comprised primarily of net interest income and gains on the sales of SBA loans generated by Q2. The mortgage banking segment operated as a separate division of the Bank. The following segment financial information has been derived from the internal financial statements of the Company which are used by management to monitor and manage financial performance. The accounting policies of the three segments are the same as those of the Company (dollars in thousands). ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Core ​ SBA ​ Consolidated ​ Banking Lending Totals Three Months Ended December 31, 2024: ​ ​ ​ ​ ​ ​ Net interest income ​ $ 13,756 ​ $ 1,706 ​ $ 15,462 Provision (credit) for credit losses – loans ​ (746) ​ 255 ​ (491) Provision (credit) for unfunded lending commitments ​ ​ (75) ​ ​ 121 ​ ​ 46 Credit for credit losses – securities ​ (6) ​ — ​ (6) Total provision (credit) for credit losses ​ ​ (827) ​ ​ 376 ​ ​ (451) Net interest income after provision ​ 14,583 ​ 1,330 ​ 15,913 Net gains on sales of loans, SBA ​ — ​ 711 ​ 711 Mortgage banking income ​ 78 ​ — ​ 78 Noninterest income ​ 5,253 ​ 850 ​ 6,103 Noninterest expense ​ 12,574 ​ 2,369 ​ 14,943 Income (loss) before taxes ​ 7,262 ​ (189) ​ 7,073 Income tax expense (benefit) ​ 893 ​ (45) ​ 848 Segment profit (loss) ​ 6,369 ​ (144) ​ 6,225 Non-cash items: ​ ​ ​ ​ ​ ​ Depreciation and amortization ​ 584 ​ 1 ​ 585 Segment assets at December 31, 2024 ​ 2,285,090 ​ 103,645 ​ 2,388,735 ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ ​ Core ​ SBA ​ Mortgage ​ Consolidated ​ Banking Lending Banking Totals Three Months Ended December 31, 2023: ​ ​ ​ ​ ​ ​ ​ ​ ​ Net interest income (loss) ​ $ 13,113 ​ $ 1,003 ​ $ (3) ​ $ 14,113 Provision (credit) for credit losses ​ (49) ​ 461 ​ ​ — ​ 412 Net interest income (loss) after provision ​ 13,162 ​ 542 ​ ​ (3) ​ 13,701 Net gains on sales of loans, SBA ​ — ​ 834 ​ ​ — ​ 834 Mortgage banking income ​ 11 ​ — ​ ​ 78 ​ 89 Noninterest income ​ 1,679 ​ 1,003 ​ ​ 100 ​ 2,782 Noninterest expense ​ 10,252 ​ 2,146 ​ ​ 3,641 ​ 16,039 Income (loss) before taxes ​ 4,589 ​ (601) ​ ​ (3,544) ​ 444 Income tax expense (benefit) ​ 541 ​ (131) ​ ​ (886) ​ (476) Segment profit (loss) ​ 4,048 ​ (470) ​ ​ (2,658) ​ 920 Non-cash items: ​ ​ ​ ​ ​ ​ ​ ​ ​ Depreciation and amortization ​ 593 ​ 2 ​ ​ 13 ​ 608 Segment assets at December 31, 2023 ​ 2,214,573 ​ 87,429 ​ ​ 6,090 ​ 2,308,092 ​
