The Company reviews its position quarterly and has asserted that at December 31, 2022, the declines outlined in the above table represent temporary declines and the Company would not be required to sell the above securities before their anticipated recovery in market value. The Company has concluded that any impairment of its investment securities portfolio is not other than temporary but is the result of interest rate changes that are not expected to result in the non-collection of principal and interest during the period.

Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral and financial condition of the borrowers. Specific loan loss allowances are established for identified losses based on a review of such information. A loan evaluated for impairment is considered to be impaired when, based on current information and events, it is probable that we will be unable to collect all amounts due according to the contractual terms of the loan agreement. All loans identified as impaired are evaluated independently. The Company does not aggregate such loans for evaluation purposes. Impairment is measured on a loan-by-loan basis for commercial and construction loans by 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. Large groups of smaller balance homogeneous loans are collectively evaluated for impairment. Accordingly, the Company does not separately identify individual consumer and residential mortgage loans for impairment disclosures, unless such loans are part of a larger relationship that is impaired or are classified as a troubled debt restructuring (“TDR”). A loan is considered to be a TDR loan when the Company grants a concession to the borrower that it would not otherwise consider because of the borrower’s financial condition. Such concessions include the reduction of interest rates, forgiveness of principal or interest, or other modifications of interest rates that are less than the current market rate for new obligations with similar risk. TDR loans that are in compliance with their modified terms and that yield a market rate at the time of modification may be removed from TDR status after one year of performance.

The first six categories are considered not criticized and are aggregated as Pass-rated. The criticized rating categories utilized by management generally follow bank regulatory definitions. The Special Mention category includes assets that are fundamentally sound yet exhibit potentially unacceptable credit risk or deteriorating trends or characteristics which, if left uncorrected, may result in deterioration of the repayment prospects for the asset or in the Company’s credit position at some future date. Loans in the Substandard category have well-defined weaknesses that jeopardize the liquidation of the debt and have a distinct possibility that some loss will be sustained if the weaknesses are not corrected. All loans that are 90 or more days past due are considered Substandard. Loans in the Doubtful category have all the weaknesses inherent in loans classified as Substandard with the added characteristic that their weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans in the Loss category are considered uncollectible and of little value that their continuance as bankable assets is not warranted. Certain residential real estate loans, construction loans, home equity loans and lines of credit, auto loans and other consumer loans are underwritten and structured using standardized criteria and characteristics, primarily payment performance, and are normally risk rated and monitored collectively on a monthly basis. These are typically loans to individuals in the consumer categories and are delineated as either performing or non-performing. To help ensure that risk ratings are accurate and reflect the present and future capacity of borrowers to repay a loan as agreed, the Bank has a structured loan rating process with several layers of internal and external oversight. Generally, consumer and residential mortgage loans are included in the Pass categories unless a specific action, such as bankruptcy, repossession, or death occurs to raise awareness of a possible credit event. The Bank’s commercial loan officers are responsible for the timely and accurate risk rating recommendation for the loans in their portfolios at origination and on an ongoing basis. The Bank’s commercial loan officers perform an annual review of all commercial relationships $750,000 or greater. Confirmation of the appropriate risk grade is included in the review on an ongoing basis. The Bank engages an external consultant to conduct loan reviews on at least a semi-annual basis. Generally, the external consultant reviews commercial relationships greater than $1,000,000 and/or all criticized relationships. Detailed reviews, including plans for resolution, are performed on loans classified as Substandard on a quarterly basis. Loans in the Special Mention and Substandard categories that are collectively evaluated for impairment are given separate consideration in the determination of the allowance.

The allowance for loan losses is maintained at a level necessary to absorb loan losses that are both probable and reasonably estimable. Management, in determining the allowance for loan losses, considers the losses inherent in its loan portfolio and changes in the nature and volume of loan activities, along with the general economic and real estate market conditions. The allowance for loan losses consists of two elements: (1) an allocated allowance, which comprises allowances established on specific loans and class allowances based on historical loss experience and current trends, and (2) an unallocated allowance based on general economic conditions and other risk factors in our markets and portfolios. We maintain a loan review system, which allows for a periodic review of our loan portfolio and the early identification of potential impaired loans. Such system takes into consideration, among other things, delinquency status, size of loans, type and market value of collateral and financial condition of the borrowers. General loan loss allowances are based upon a combination of factors including, but not limited to, actual loan loss experience, composition of the loan portfolio, current economic conditions, management’s judgment and losses which are probable and reasonably estimable. The allowance is increased through provisions charged against current earnings and recoveries of previously charged-off loans. Loans that are determined to be uncollectible are charged against the allowance. While management uses available information to recognize probable and reasonably estimable loan losses, future loss provisions may be necessary, based on changing economic conditions. Payments received on impaired loans generally are either applied against principal or reported as interest income, according to management’s judgment as to the collectability of principal. The allowance for loan losses as of December 31 , 2022 was maintained at a level that represents management’s best estimate of losses inherent in the loan portfolio, and such losses were both probable and reasonably estimable. In addition, the FDIC and the Pennsylvania Department of Banking and Securities, as an integral part of their examination process, have periodically reviewed our allowance for loan losses. The banking regulators may require that we recognize additions to the allowance based on its analysis and review of information available to it at the time of its examination. Management reviews the loan portfolio on a quarterly basis using a defined, consistently applied process in order to make appropriate and timely adjustments to the allowance for loan losses (“ALL”). When information confirms all or part of specific loans to be uncollectible, these amounts are promptly charged off against the ALL. The following table summarizes changes in the primary segments of the ALL during the three months ended December 31, 2022 and 2021 (in thousands): Home Obligations of Equity States and Loans and Real Estate Loans Commercial Political Lines of Other Residential Construction Commercial Loans Subdivisions Credit Auto Loans Loans Unallocated Total ALL balance at September 30, 2022 $ 5,122 $ 319 $ 10,754 $ 698 $ 283 $ 361 $ 22 $ 22 $ 947 $ 18,528 Charge-offs - - - - - - (21 ) - - (21 ) Recoveries 2 - 1 - - 51 30 - - 84 Provision 162 9 439 350 (8 ) (40 ) (17 ) - (745 ) 150 ALL balance at December 31, 2022 $ 5,286 $ 328 $ 11,194 $ 1,048 $ 275 $ 372 $ 14 $ 22 $ 202 $ 18,741 ALL balance at September 30, 2021 $ 4,114 $ 187 $ 10,470 $ 1,041 $ 393 $ 318 $ 232 $ 21 $ 1,337 $ 18,113 Charge-offs (6 ) - - - - - (6 ) - - (12 ) Recoveries 72 - 1 - - 2 34 - - 109 Provision (82 ) 54 136 183 (128 ) (23 ) (64 ) - (76 ) - ALL balance at December 31, 2021 $ 4,098 $ 241 $ 10,607 $ 1,224 $ 265 $ 297 $ 196 $ 21 $ 1,261 $ 18,210 During the three months ended December 31, 2022, the Company recorded provision expense for the residential real estate loans, construction real estate loans, commercial real estate loans and commercial loans segments due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Credit provisions were recorded for loan loss for the obligations of states and political subdivisions, home equity loans and lines of credit and auto loans due to either decreased loan balances, improved asset quality, changes in the loan mix within the pool, and/or decreased charge-off activity in those segments. During the three months ended December 31, 2021, the Company recorded provision expense for the construction real estate loans, commercial real estate loans and commercial loans segments, due to either increased loan balances, changes in the loan mix within the pool, and/or charge-off activity in those segments. Provision expense was also recorded for possible loan losses due to the economic slowdown caused by COVID-19 restrictions. Credit provisions were recorded for loan loss for the residential real estate loans, obligations of states and political subdivisions, home equity loans and lines of credit and auto loans segments due to either decreased loan balances, changes in the loan mix within the pool, and/or decreased charge-off activity in those segments. The following table summarizes the primary segments of the ALL, segregated into two categories, the amount required for loans individually evaluated for impairment and the amount required for loans collectively evaluated for impairment as of December 31, 2022 and September 30, 2022 (in thousands): Home Obligations of Equity States and Loans and Real Estate Loans Commercial Political Lines of Other Residential Construction Commercial Loans Subdivisions Credit Auto Loans Loans Unallocated Total Individually evaluated for impairment $ 11 $ - $ 420 $ 249 $ - $ - $ - $ - $ - $ 680 Collectively evaluated for impairment 5,275 328 10,774 799 275 372 14 22 202 18,061 ALL balance at December 31, 2022 $ 5,286 $ 328 $ 11,194 $ 1,048 $ 275 $ 372 $ 14 $ 22 $ 202 $ 18,741 Individually evaluated for impairment $ 12 $ - $ 301 $ 38 $ - $ - $ - $ - $ - $ 351 Collectively evaluated for impairment 5,110 319 10,453 660 283 361 22 22 947 18,177 ALL balance at September 30, 2022 $ 5,122 $ 319 $ 10,754 $ 698 $ 283 $ 361 $ 22 $ 22 $ 947 $ 18,528 The allowance for loan losses is based on estimates, and actual losses will vary from current estimates. Management believes that the granularity of the homogeneous pools and the related historical loss ratios and other qualitative factors, as well as the consistency in the application of assumptions, result in an ALL that is representative of the risk found in the components of the portfolio at any given date. Despite the above allocations, the allowance for loan losses is general in nature and is available to absorb losses from any loan segment. There were no new troubled debt restructurings granted during the three months ended December 31, 2021. The following is a summary of troubled debt restructuring granted during the three months ended December 31, 2022 (dollars in thousands): For the Three Months Ended December 31, 2022 Number of Contracts Pre-Modification Outstanding Recorded Investment Post-Modification Outstanding Recorded Investment Troubled Debt Restructurings Real estate loans: Residential 1 $ 51 $ 54 Construction — — — Commercial — — — Commercial — — — Obligations of states and political subdivisions — — — Home equity loans and lines of credit — — — Auto loans — — — Other — — — Total 1 $ 51 $ 54 For the three months ended December 31, 2022 and 2021, no loans defaulted on a restructuring agreement within one year of modification.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]
Equity Incentive Plan	9 . Equity Incentive Plan The Company previously maintained the ESSA Bancorp, Inc. 2007 Equity Incentive Plan (the “Plan”). The Plan provided for a total of 2,377,326 shares of common stock for issuance upon the grant or exercise of awards. Of the shares that were available under the Plan, 1,698,090 were available to be issued in connection with the exercise of stock options and 679,236 were available to be issued as restricted stock. The Plan allowed for the granting of non-qualified stock options (“NSOs”), incentive stock options (“ISOs”), and restricted stock. Options granted under the plan were granted at no less than the fair value of the Company’s common stock on the date of the grant. As of the effective date of the 2016 Equity Incentive Plan (detailed below), no further grants will be made under the Plan and forfeitures of outstanding awards under the Plan will be added to the shares available under the 2016 Equity Incentive Plan. The Company replaced the 2007 Equity Incentive Plan with the ESSA Bancorp, Inc. 2016 Equity Incentive Plan (the “2016 Plan”) which was approved by shareholders on March 3, 2016. The 2016 Plan provides for a total of 250,000 shares of common stock for issuance upon the grant or exercise of awards. The 2016 Plan allows for the granting of restricted stock, restricted stock units, ISOs and NSOs. The Company classifies share-based compensation for employees and outside directors within “Compensation and employee benefits” in the Consolidated Statement of Operations to correspond with the same line item as compensation paid. Restricted stock shares outstanding at December 31, 2022 vest over periods ranging from 4 to 45 months. The product of the number of shares granted and the grant date market price of the Company’s common stock determines the fair value of restricted shares under the Company’s restricted stock plan. The Company expenses the fair value of all share based compensation grants over the requisite service period. For the three months ended December 31, 2022 and 2021, the Company recorded $295,000 and $262,000 of share-based compensation expense, respectively, comprised of restricted stock expense. Expected future compensation expense relating to the restricted shares outstanding at December 31, 2022 is $829,000 over the remaining vesting period of 3.75 years. The following is a summary of the status of the Company’s restricted stock as of December 31, 2022, and changes therein during the three month period then ended: Number of Restricted Weighted- average Grant Date Fair Value Nonvested at September 30, 2022 35,639 $ 14.88 Granted 31,696 19.06 Vested (625 ) 15.34 Forfeited — — Nonvested at December 31, 2022 66,710 $ 16.84

Fair Value Disclosures [Abstract]
Fair Value	10. Fair Value The following disclosures show the hierarchal disclosure framework associated within the level of pricing observations utilized in measuring assets and liabilities at fair value. The definition of fair value maintains the exchange price notion in earlier definitions of fair value but focuses on the exit price of the asset or liability. The exit price is the price that would be received to sell the asset or paid to transfer the liability adjusted for certain inherent risks and restrictions. Expanded disclosures are also required about the use of fair value to measure assets and liabilities. Assets and Liabilities Required to be Measured and Reported at Fair Value on a Recurring Basis The following tables provide the fair value for assets and liabilities required to be measured and reported at fair value on a recurring basis on the Consolidated Balance Sheet as of December 31, 2022 and September 30, 2022 by level within the fair value hierarchy (in thousands). Recurring Fair Value Measurements at Reporting Date December 31, 2022 Assets Level I Level II Level III Total Investment securities available for sale: Mortgage backed securities $ - $ 107,749 $ - $ 107,749 Obligations of states and political subdivisions - 9,958 - 9,958 U.S. government agencies - 9,338 - 9,338 Corporate obligations - 63,355 7,199 70,554 Other debt securities - 7,589 - 7,589 Total debt securities $ - $ 197,989 $ 7,199 $ 205,188 Equity securities- financial services 38 - - 38 Derivatives and hedging activities - 22,510 - 22,510 Liabilities Derivatives and hedging activities $ - $ 8,371 $ - $ 8,371 September 30, 2022 Assets Level I Level II Level III Total Investment securities available for sale: Mortgage backed securities $ - $ 110,160 $ - $ 110,160 Obligations of states and political subdivisions - 9,920 - 9,920 U.S. government agencies - 9,330 - 9,330 Corporate obligations - 63,745 7,374 71,119 Other debt securities - 8,118 - 8,118 Total debt securities $ - $ 201,273 $ 7,374 $ 208,647 Equity securities-financial services 36 - - 36 Derivatives and hedging activities - 24,481 - 24,481 Liabilities: Derivatives and hedging activities $ - $ 9,176 $ - $ 9,176 The following table presents a summary of changes in the fair value of the Company’s Level III investments for the three month periods ended December 31, 2022 and 2021 (in thousands). Fair Value Measurement Using Significant Unobservable Inputs (Level III) Three Months Ended December 31, 2022 December 31, 2021 Beginning balance $ 7,374 $ 11,112 Purchases, sales, issuances, settlements, net - — Total unrealized (loss) gain: Included in earnings - — Included in other comprehensive (loss) income (175 ) (175 ) Transfers in and/or out of Level III - - $ 7,199 $ 10,937 Each financial asset and liability is identified as having been valued according to a specified level of input, 1, 2 or 3. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Fair values determined by Level 2 inputs utilize inputs other than quoted prices included in Level 1 that are observable for the asset, either directly or indirectly. Level 2 inputs include quoted prices for similar assets in active markets, and inputs other than quoted prices that are observable for the asset or liability. Level 3 inputs are unobservable inputs for the asset, and include situations where there is little, if any, market activity for the asset or liability. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy, within which the fair value measurement in its entirety falls, has been determined based on the lowest level input that is significant to the fair value measurement in its entirety. The Company’s assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment and considers factors specific to the asset. The measurement of fair value should be consistent with one of the following valuation techniques: market approach, income approach, and/or cost approach. The market approach uses prices and other relevant information generated by market transactions involving identical or comparable assets or liabilities (including a business). For example, valuation techniques consistent with the market approach often use market multiples derived from a set of comparable. Multiples might lie in ranges with a different multiple for each comparable. The selection of where within the range the appropriate multiple falls requires judgment, considering factors specific to the measurement (qualitative and quantitative). Valuation techniques consistent with the market approach include matrix pricing. Matrix pricing is a mathematical technique used principally to value debt securities without relying exclusively on quoted prices for the specific securities, but rather by relying on a security’s relationship to other benchmark quoted securities. Most of the securities classified as available for sale are reported at fair value utilizing Level 2 inputs. For these securities, the Company obtains fair value measurements from an independent pricing service. The fair value measurements consider observable data that may include dealer quoted market spreads, cash flows, the U.S. Treasury yield curve, live trading levels, trade execution data, market consensus prepayment speeds, credit information and the bond’s terms and conditions, among other things. Securities reported at fair value utilizing Level 1 inputs are limited to actively traded equity securities whose market price is readily available from the New York Stock Exchange or the NASDAQ exchange. A few securities are valued using Level 3 inputs, all of these are classified as available for sale and are reported at fair value using Level 3 inputs. Assets and Liabilities Required to be Measured and Reported on a Non-Recurring Basis The following tables provide the fair value for assets required to be measured and reported at fair value on a non-recurring basis on the Consolidated Balance Sheet as of December 31, 2022 and September 30, 2022 by level within the fair value hierarchy: Non-Recurring Fair Value Measurements at Reporting Date (in thousands) December 31, 2022 Level I Level II Level III Total Foreclosed real estate $ - $ - $ 26 $ 26 Impaired loans - - 13,685 13,685 September 30, 2022 Level I Level II Level III Total Foreclosed real estate $ - $ - $ 29 $ 29 Impaired loans - - 14,151 14,151 The following tables present additional quantitative information about assets measured at fair value on a nonrecurring basis and for which the Company has utilized Level 3 inputs to determine fair value: Quantitative Information about Level 3 Fair Value Measurements (dollars in thousands) Fair Value Estimate Valuation Techniques Unobservable Input Range (Average) December 31, 2022 Impaired loans $ 13,685 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 35% (20.6%) Foreclosed real estate owned 26 Appraisal of collateral (1) Appraisal adjustments (2) 35% (35.0%) Quantitative Information about Level 3 Fair Value Measurements (dollars in thousands) Fair Value Estimate Valuation Techniques Unobservable Input Range (Average) September 30, 2022 Impaired loans $ 14,151 Appraisal of collateral (1) Appraisal adjustments (2) 0% to 35% (20.6%) Foreclosed real estate owned 29 Appraisal of collateral (1) Appraisal adjustments (2) 20% (20.0%) (1) Fair value is generally determined through independent appraisals of the underlying collateral, which generally include various level 3 inputs which are not identifiable. (2) Appraisals may be adjusted by management for qualitative factors such as economic conditions and estimated liquidation expenses. The range of liquidation expenses and other appraisal adjustments are presented as a percent of the appraisal. Foreclosed real estate is measured at fair value, less cost to sell at the date of foreclosure, valuations are periodically performed by management and the assets are carried at the lower of carrying amount or fair value, less cost to sell. Income and expenses from operations and changes in valuation allowance are included in the net expenses from foreclosed real estate. Impaired loans are reported at fair value utilizing level three inputs. For these loans, a review of the collateral is conducted and an appropriate allowance for loan losses is allocated to the loan. At December 31, 2022, 48 impaired loans with a carrying value of $14.4 million were reduced by specific valuation allowance totaling $680,000 resulting in a net fair value of $13.7 million based on Level 3 inputs. At September 30, 2022, 49 impaired loans with a carrying value of $14.5 million were reduced by a specific valuation totaling $351,000 resulting in a net fair value of $14.1 million based on Level 3 inputs. Assets and Liabilities not Required to be Measured and Reported at Fair Value The following tables provide the carrying value and fair value for certain financial instruments that are not required to be measured or reported at fair value on the Consolidated Balance Sheet at December 31, 2022 and September 30, 2022 by level within the fair value hierarchy: December 31, 2022 (in thousands) Carrying Level I Level II Level III Total Fair Value Financial assets: Investment securities held to maturity $ 56,025 $ - $ 47,253 $ - $ 47,253 Loans receivable, net 1,504,400 - - 1,405,406 1,405,406 Mortgage servicing rights 776 - - 1,350 1,350 Financial liabilities: Deposits $ 1,369,844 $ 1,163,222 $ - $ 200,998 $ 1,364,220 Short term borrowings 305,582 — — 290,528 290,528 September 30, 2022 (in thousands) Carrying Level I Level II Level III Total Fair Value Financial assets: Investment securities held to maturity $ 57,285 $ - $ 47,546 $ - $ 47,546 Loans receivable, net 1,435,783 - - 1,351,823 1,351,823 Mortgage servicing rights 788 - - 1,390 1,390 Financial liabilities: Deposits $ 1,380,021 $ 1,246,353 $ - $ 128,533 $ 1,374,886 Short-term borrowings 230,810 - - 215,287 215,287

Derivative Instruments And Hedging Activities Disclosure [Abstract]
Derivatives and Hedging Activities	12. Derivatives and Hedging Activities Risk Management Objective of Using Derivatives The Company is exposed to certain risks arising from both its business operations and economic conditions. The Company principally manages its exposures to a wide variety of business and operational risks through management of its core business activities. The Company manages economic risks, including interest rate, liquidity, and credit risk, primarily by managing the amount, sources, and duration of its assets and liabilities and through the use of derivative financial instruments. Specifically, the Company enters into derivative financial instruments to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. The Company’s derivative financial instruments are used to manage differences in the amount, timing, and duration of the Company’s known or expected cash receipts and its known or expected cash payments principally related to certain variable rate borrowings. Fair Values of Derivative Instruments on the Consolidated Balance Sheet The table below presents the fair value of the Company’s derivative financial instruments as of December 31, 2022 and September 30, 2022 (in thousands). Fair Values of Derivative Instruments Asset Derivatives As of December 31, 2022 As of September 30, 2022 Hedged Item Notional Amount Fair Value Notional Amount Fair Value FHLB Advances $ 225,000 $ 14,143 $ 225,000 $ 15,310 Commercial Loans 76,804 8,367 79,602 9,171 Total $ 301,804 $ 22,510 $ 304,602 $ 24,481 Fair Values of Derivative Instruments Liability Derivatives As of December 31, 2022 As of September 30, 2022 Hedged Item Notional Amount Fair Value Notional Amount Fair Value Commercial Loans $ 108,669 $ 8,371 $ 111,668 $ 9,176 Total $ 108,669 $ 8,371 $ 111,668 $ 9,176 Cash Flow Hedges of Interest Rate Risk The Company’s objectives in using interest rate derivatives are to add stability to interest income and expense and to manage its exposure to interest rate movements. To accomplish this objective, the Company has entered into interest rate swaps as part of its interest rate risk management strategy. These interest rate swaps are designated as cash flow hedges and involve the receipt of variable rate amounts from a counterparty in exchange for the Company making fixed payments. As of December 31, 2022, the Company had ten interest rate swaps with a notional principal amount of $225.0 million associated with the Company’s cash outflows associated with various FHLB advances and $185.5 million associated with associated with various commercial loans. For derivatives designated as cash flow hedges, the effective portion of changes in the fair value of the derivative is initially reported in other comprehensive income (outside of earnings), net of tax, and subsequently reclassified to earnings when the hedged transaction affects earnings, and the ineffective portion of changes in the fair value of the derivative is recognized directly in earnings. The Company assesses the effectiveness of each hedging relationship by comparing the changes in cash flows of the derivative hedging instrument with the changes in cash flows of the designated hedged transactions. The Company did not recognize any hedge ineffectiveness in earnings during the periods ended December 31, 2022 and 2021. Amounts reported in accumulated other comprehensive income (loss) related to derivatives that will be reclassified to interest income/expense as interest payments are made/received on the Company’s variable-rate assets/liabilities. During the three months ended December 31, 2022, the Company had $1.8 million of gains, which resulted in a decrease to interest expense. During the three months ended December 31, 2021, the Company had $236,000 of losses which resulted in an increase to interest expense. During the next twelve months, the Company estimates that $8.7 million will be reclassified as a decrease to interest expense. The table below presents the effect of the Company’s cash flow hedge accounting on Accumulated Other Comprehensive Income (Loss) for the three month periods ended December 31, 2022 and 2021 (in thousands).

The Company also has agreements with certain of its derivative counterparties that contain a provision where if the Company fails to maintain its status as a well / adequately capitalized institution, then the counterparty could terminate the derivative positions and the Company would be required to settle its obligations under the agreements. As of December 31, 2022 and September 30, 2022, the Company had no derivatives in a net liability position and was not required to post collateral against its obligations under these agreements. If the Company had breached any of these provisions at December 31, 2022 and September 30, 2022, it could have been required to settle its obligations under the agreements at the termination value.

Commitments And Contingencies Disclosure [Abstract]
Contingent Liabilities	13. Contingent Liabilities Legal Proceedings The Company and its subsidiaries are subject to various legal actions arising in the normal course of business. In the opinion of Management, the resolution of these legal actions is not expected to have a material adverse effect on the Company’s results of operations. The Company and its subsidiary, ESSA Bank and Trust (“ESSA B&T”) were named as defendants, among others, in an action commenced on December 8, 2016 by one plaintiff who sought to pursue the suit as a class action on behalf of the entire class of people similarly situated. The plaintiff alleged that a bank previously acquired by the Company received unearned fees and kickbacks in the process of making loans, in violation of the Real Estate Settlement Procedures Act. In an order dated January 29, 2018, the district court granted the defendants’ motion to dismiss the case. The plaintiff appealed the court’s ruling. In an opinion and order dated April 26, 2019, the appellate court reversed the district court’s order dismissing the plaintiff’s case against the Company and remanded the case to the district court in order to continue the litigation. The litigation is now proceeding before the district court. On December 9, 2019, the court permitted an amendment to the complaint to add two new plaintiffs to the case asserting similar claims. On May 21, 2020, the court granted the plaintiffs’ motion for class certification. The case is currently in the expert witness discovery phase and the Company and ESSA B&T will continue to vigorously defend against plaintiffs’ allegations. To the extent that this matter could result in exposure to the Company and/or ESSA B&T, the amount or range of such exposure is not currently estimable but could be substantial. On May 29, 2020, the Company and ESSA B&T were named as defendants in a second action commenced by three plaintiffs who also seek to pursue this action as a class action on behalf of the entire class of people similarly situated. The plaintiffs allege that a bank previously acquired by the Company received unearned fees and kickbacks from a different title company than the one involved in the previously discussed litigation in the process of making loans. The original complaint alleged violations of the Real Estate Settlement Procedures Act, the Sherman Act, and the Racketeer Influenced and Corrupt Organizations Act (“RICO”). The plaintiffs filed an Amended Complaint on September 30, 2020 that dropped the RICO claim, but they are continuing to pursue the Real Estate Settlement Procedures Act and Sherman Act claims. The defendants moved to dismiss the Sherman Act claim on October 14, 2020, and that motion was denied on April 2, 2021. The case is currently in the fact discovery phase and plaintiffs have moved to have the court certify the matter as a class action. The Company and ESSA B&T intend to vigorously defend against plaintiffs’ allegations. To the extent that this matter could result in exposure to the Company and/or ESSA B&T, the amount or range of such exposure is not currently estimable but could be substantial.

Revenue From Contract With Customer [Abstract]
Revenue Recognition	14. Management determined that the primary sources of revenue associated with financial instruments, including interest income on loans and investments, along with certain noninterest revenue sources including investment security gains, loan servicing charges, gains on the sale of loans, and earnings on bank owned life insurance are not within the scope of Topic 606. Noninterest income within the scope of Topic 606 are as follows: Trust and Investment Fees Trust and asset management income is primarily comprised of fees earned from the management and administration of trusts and other customer assets. The Company’s performance obligation is generally satisfied over time and the resulting fees are recognized monthly, based upon the month-end market value of the assets under management and the applicable fee rate. Payment is generally received a few days after month end through a direct charge to customer’s accounts. The Company does not earn performance-based incentives. Optional services such as real estate sales and tax return preparation services are also available to existing trust and asset management customers. The Company’s performance obligation for these transactional-based services is generally satisfied, and related revenue recognized, at a point in time ( i.e. as incurred). Payment is received shortly after services are rendered. Service Charges on Deposit Accounts Service charges on deposit accounts consist of account analysis fees (i.e. net fees earned on analyzed business and public checking accounts), monthly service fees, check orders, and other deposit account related fees. The Company’s performance obligation for account analysis fees and monthly service fees is generally satisfied, and the related revenue recognized, over the period in which the service is provided. Check orders and other deposit account related fees are largely transactional based, and therefore, the Company’s performance obligation is satisfied, and related revenue recognized, at a point in time. Payment for service charges on deposit accounts is primarily received immediately or in the following month through a direct charge to customers’ accounts. Fees, Exchange, and Other Service Charges Fees, interchange, and other service charges are primarily comprised of debit card income, ATM fees, cash management income, and other services charges. Debit card income is primarily comprised of interchange fees earned whenever the Company’s debit cards are processed through card payment networks such as Mastercard. ATM fees are primarily generated when a Company cardholder uses a non-Company ATM or a non-Company cardholder uses a company ATM. Other service charges include revenue from processing wire transfers, bill pay service, cashier’s checks, and other services. The Company’s performance obligation for fees, exchange, and other service charges are largely satisfied, and related revenue recognized when the services are rendered or upon completion. Payment is typically received immediately or in the following month. Insurance Commissions Insurance income primarily consists of commissions received on product sales. The Company acts as an intermediary between the Company’s customer and the insurance carrier. The Company’s performance obligation is generally satisfied upon the issuance of the policy. Shortly after the policy is issued, the carrier remits the commission payment to the Company, and the Company recognizes the revenue.

Leases [Abstract]
Leases	15. A lease is defined as a contract, or part of a contract, that conveys the right to control the use of identified property, plant or equipment for a period of time in exchange for consideration. For the Company, Topic 842 primarily affects the accounting treatment for operating lease agreements in which the Company is the lessee. Lessee Accounting Substantially all of the leases in which the Company is the lessee are comprised of real estate property for branches, ATM locations, and office space with terms extending through 2044. In accordance with Topic 842, operating lease agreements are required to be recognized on the Consolidated Balance sheet as a right-of-use (“ROU”) asset and a corresponding lease liability. The following table presents the Consolidated Balance Sheet classification of the Company’s ROU assets and lease liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the Consolidated Balance sheet. (in thousands) December 31, 2022 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 5,841 Total Lease Right-Of-Use Assets $ 5,841 (in thousands) December 31, 2022 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 6,053 Total Lease Liabilities $ 6,053 (in thousands) September 30, 2022 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 6,075 Total Lease Right-Of-Use Assets $ 6,075 (in thousands) September 30, 2022 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 6,275 Total Lease Liabilities $ 6,275 The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term.

Summary of Balance Sheet Operating Lease Right-of-Use Assets and Lease Liabilities	The following table presents the Consolidated Balance Sheet classification of the Company’s ROU assets and lease liabilities. The Company elected not to include short-term leases (i.e., leases with initial terms of twelve months or less), or equipment leases (deemed immaterial) on the Consolidated Balance sheet. (in thousands) December 31, 2022 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 5,841 Total Lease Right-Of-Use Assets $ 5,841 (in thousands) December 31, 2022 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 6,053 Total Lease Liabilities $ 6,053 (in thousands) September 30, 2022 Lease Right-of-Use Assets Classification Operating lease right-of-use assets Other assets $ 6,075 Total Lease Right-Of-Use Assets $ 6,075 (in thousands) September 30, 2022 Lease Liabilities Classification Operating lease Liabilities Other liabilities $ 6,275 Total Lease Liabilities $ 6,275
Summary of Lease Term and Discount Rate	The calculated amount of the ROU assets and lease liabilities in the table above are impacted by the length of the lease term and the discount rate used to present value the minimum lease payments. The Company’s lease agreements often include one or more options to renew at the Company’s discretion. If at lease inception, the Company considers the exercising of a renewal option to be reasonably certain, the Company will include the extended term in the calculation of the ROU asset and lease liability. Regarding the discount rate, Topic 842 requires the use of the rate implicit in the lease whenever this rate is readily determinable. As this rate is rarely determinable, the Company utilizes its incremental borrowing rate at lease inception, on a collateralized basis, over a similar term. December 31, 2022 Weighted average remaining lease term Operating leases 12.2 years Weighted average discount rate Operating leases 2.39 %
Summary of Components of Lease Cost	The following table represents lease costs and other lease information. As the Company elected, for all classes of underlying assets, not to separate lease and non-lease components and instead to account for them as a single lease component, the variable lease cost primarily represents variable payments such as common area maintenance and utilities. Lease Costs (in thousands) Three Months Ended December 31, 2022 Operating lease cost $ 238 Variable lease cost 52 Net lease cost $ 290 Lease Costs (in thousands) Three Months Ended December 31, 2021 Operating lease cost $ 261 Variable lease cost 79 Net lease cost $ 340
