PCSB Financial Corporation and Subsidiaries Notes to Consolidated Financial Statements (unaudited) Note 1. Basis of Presentation Nature of Operations: PCSB Financial Corporation (the “Holding Company” and together with its direct and indirect subsidiaries, the “Company”) is a Maryland corporation organized by PCSB Bank (the “Bank”) for the purpose of acquiring all of the capital stock of the Bank issued in the Bank's conversion to stock ownership on April 20, 2017. At December 31, 2021, the significant assets of the Holding Company were the capital stock of the Bank, cash deposited in the Bank, and a loan to the PCSB Bank Employee Stock Ownership Plan (“ESOP”). The liabilities of the Holding Company were insignificant. The Company is subject to the financial reporting requirements of the Securities Exchange Act of 1934, as amended, and regulation and examination by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) and the New York State Department of Financial Services (the “NYSDFS”). PCSB Bank is a community-oriented financial institution that provides financial services to individuals and businesses within its market area of Putnam, Southern Dutchess, Rockland and Westchester Counties in New York. The Bank is a state-chartered commercial bank, and its deposits are insured up to applicable limits by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”). The Bank’s primary regulators are the FDIC and the NYSDFS. Basis of Presentation: The unaudited consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), and include the accounts of the Holding Company, the Bank and the Bank's two subsidiaries - PCSB Funding Corp. and UpCounty Realty Corp. (formerly PCSB Realty Ltd.). PCSB Funding Corp. is a real estate investment trust that holds certain mortgage assets. UpCounty Realty Corp. is a corporation that holds certain properties foreclosed upon by the Bank. All intercompany transactions and balances have been eliminated in consolidation. The unaudited consolidated financial statements contained herein reflect all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Such adjustments are the only adjustments reflected in the consolidated financial statements contained herein. The results of operations for the current period presented are not necessarily indicative of the results of operations that may be expected for the entire current fiscal year. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended June 30, 2021, included in the Company's Annual Report on Form 10-K. Certain prior period amounts have been reclassified to conform to the current presentation. Reclassifications had no effect on prior period net income or equity. Loans Receivable Held For Sale: Loans receivable held for sale are those loans which management has the intent to sell in the foreseeable future, and are carried at the lower of aggregate cost or market value. Net unrealized losses, if any, are recognized by a valuation allowance through a charge to noninterest income. Realized gains and losses on the sale of loans are recognized on the trade date and are determined by the difference between the sale proceeds and the carrying value of the loans. Loans may be sold with servicing rights released or retained. At the time of the sale, management records a servicing asset for the value of any retained servicing rights, which represents the present value of the differential between the contractual servicing fee and adequate compensation, defined as the fee a sub-servicer would require to assume the role of servicer, after considering the estimated effects of prepayments. Transfers of financial assets are accounted for as sales when control over the assets has been surrendered. Control over transferred assets is deemed to be surrendered when (1) the assets have been isolated from the Company, put presumptively beyond the reach of the transferor and its creditors, even in bankruptcy or other receivership, (2) the transferee obtains the right (free of conditions that constrain it from taking advantage of that right) to pledge or exchange the transferred assets, and (3) the transferor does not maintain effective control over the transferred assets through either (a) an agreement that both entitles and obligates the transferor to repurchase or redeem the assets 9

before maturity or (b) the ability to unilaterally cause the holder to return specific assets, other than through a cleanup call. Assets Held For Sale: Assets held for sale are those assets which management has the intent to sell in the foreseeable future, and are carried at the lower of aggregate cost or fair value, less estimated costs to sell, in the period in which the held for sale criteria are met and every subsequent period until the asset is sold. The carrying amount of the asset is adjusted for subsequent increases or decreases in its fair value, less estimated cost to sell, except that any subsequent increase cannot exceed the cumulative loss previously recognized. Such assets are not depreciated or amortized while they are classified as held for sale. Realized gains and losses on the sale of the asset is recognized when the asset is sold and is determined by the difference between the sale proceeds and the carrying value of the asset. Assets classified as held for sale totaled $1.5 million as of both December 31, 2021 and June 30, 2021 and are included in other assets on the consolidated balance sheet. During the three and six months ended December 31, 2021, the Company sold $398,000 in assets held for sale resulting in gains on sale of $548,000. Risks and Uncertainties: The COVID-19 pandemic has created extensive disruptions to the global and U.S. economies and to the lives of individuals throughout the world. Governments, businesses, and the public have taken unprecedented actions to contain the spread of COVID-19 and to mitigate its effects, including vaccination mandates, quarantines, travel bans, shelter-in-place orders, closures of businesses and schools, fiscal and monetary stimulus, and legislation designed to deliver financial aid and other relief. While the scope, duration, and full effects of COVID-19 on the economy continue to evolve and are not fully known, the pandemic and the efforts to contain it have disrupted global economic activity, adversely affected the functioning of financial markets, impacted market interest rates, increased economic and market uncertainty, and disrupted trade and supply chains. Many of the emergency actions taken to mitigate the effects of the pandemic have since been reduced or eliminated, resulting in an improved local and national economic environment, however the ultimate financial impact of the pandemic on our borrowers, and therefore on our credit quality and financial performance, is still unknown at this time. The pandemic may continue to adversely impact consumers and several industries within our geographic footprint and impair the ability of the Company’s customers to fulfill their contractual obligations to the Company. This could cause the Company to experience a material adverse effect on our business operations, asset valuations, financial condition, and results of operations. Material adverse impacts may include, but are not limited to, the valuation impairments of the Company’s intangible assets, investments, loans receivable, or deferred tax assets. Additionally, it is reasonably possible that the Company’s allowance for loan loss estimate as of December 31, 2021 could change in the near term and could result in a material change to the Company’s provision for loan losses, earnings and capital. Use of Estimates: To prepare financial statements in conformity with GAAP management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. Note 2. Recent Accounting Pronouncements The pronouncements discussed below are not intended to be an all-inclusive list, but rather only those pronouncements that the Company has determined could potentially have a material impact on our financial position, results of operations or disclosures. There were no accounting standards adopted in the current period. Future Application of Accounting Pronouncements Previously Issued In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 which affects entities holding financial assets that are not accounted for at fair value through net income, including loans, debt securities, and other financial assets. The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by recording an allowance for current expected credit losses. In October 2019, the FASB unanimously voted to delay the implementation of the standard for three years for certain companies, including small reporting companies (as defined by the SEC), non-SEC public companies and private companies. The Company currently qualifies as a small reporting company and is subject to the delayed implementation. Therefore, the amendments in this update 10

will be effective for the Company for the fiscal year beginning on July 1, 2023, including interim periods within that fiscal year. The Company is actively working through the provisions of the Update. Management has established a steering committee which is identifying the methodologies and the additional data requirements necessary to implement the Update and has engaged a third-party software service provider to assist in the Company's implementation. Management is currently evaluating the impact that ASU 2016-13 will have on the Company’s consolidated financial position, results of operations and disclosures. The FASB issued ASU 2020-04 “Reference Rate Reform” and ASU 2021-01 “Reference Rate Reform Scope” which collectively address accounting considerations related to the expected discontinuation of LIBOR as a reference rate for financial contracts. These Updates provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform (codified in ASC 848). They include optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables), were not substantial (assets within the scope of ASC 470, Debt) and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases, and other Topics) of the existing contract. They also include optional expedients and exceptions for contract modifications and hedge accounting that apply to derivative instruments impacted by the market-wide discounting transition. The Updates also allow for a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The guidance in these ASUs are effective as of March 12, 2020 through December 31, 2022. The Company has not yet elected to apply the practical expedients contained in these Updates and does not expect significant impact to the consolidated financial statements upon adoption. Note 3.

Non-U.S. government and agency obligations are internally pass rated and are subject to quarterly credit monitoring. There were no securities for which the Company believes it is not probable that it will collect all amounts due according to the contractual terms of the security as of December 31, 2021 or June 30, 2021. Management believes the unrealized losses are primarily a result of changes in market interest rates. The Company has determined that it does not intend to sell, or it is not more likely than not that it will be required to sell, its securities that are in an unrealized loss position prior to the recovery of its amortized cost basis. Therefore, the Company did not consider any securities to be other-than-temporarily impaired as of December 31, 2021 or June 30, 2021. 13

Such loans are excluded because the loans are in pools that are considered performing. The discounts arising from recording these loans at fair value upon acquisition were due in part to credit quality and the accretable yield is being recognized as interest income over the life of the loans based on expected cash flows.

Troubled Debt Restructurings The terms of certain loans have been modified as troubled debt restructurings (“TDR’s”). The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan. All TDRs are considered impaired loans. As of December 31, 2021 and June 30, 2021, the Company had 8 and 12 loans, classified as TDRs totaling $1.6 million and $3.1 million, including $1.2 million and $2.7 million, respectively, of loans still accruing interest. The Company has allocated $119,000 and $121,000, respectively, of specific reserves to customers whose loan terms have been modified in TDRs as of December 31, 2021 and June 30, 2021. As of December 31, 2021, the Company has committed to lend an additional $1,000 to customers with outstanding loans that are classified as TDRs. The Company did not modify any loans during the three or six months ended December 31, 2021 or 2020 that were classified as TDRs. There were no defaults of TDRs occurring in the three or six months ended December 31, 2021 or December 31, 2020 that were modified in the twelve months prior to default. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law. Section 4013 of the CARES Act, “Temporary Relief From Troubled Debt Restructurings,” provides banks the option to temporarily suspend certain requirements under U.S. GAAP related to TDRs for a limited period of time to account for the effects of COVID-19. On December 27, 2020, the Consolidated Appropriations Act 2021 was signed into law. Section 541 of this legislation, “Extension of Temporary Relief From Troubled Debt Restructurings and Insurer Clarification,” extends Section 4013 of the CARES Act to the earlier of January 1, 2022 or 60 days after the termination of the national emergency declared relating to COVID-19. This legislation expired on January 1, 2022. Additionally, on April 7, 2020, the banking agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, issued a statement, “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working With Customers Affected by the Coronavirus (Revised)” (“Interagency Statement”), to encourage banks to work prudently with borrowers and to describe the agencies’ interpretation of how accounting rules under ASC 310-40, “Troubled Debt Restructurings by Creditors,” apply to certain COVID-19-related modifications. During the three and six months ended December 31, 2021, the Company granted or extended loan payment deferrals for 3 and 5 residential mortgage, commercial mortgage, and commercial loans totaling $3.9 million and $5.9 million, respectively. In accordance with either the CARES Act (as amended) or Interagency Statement, these modifications are not considered TDRs. The Company had 7 and 19 loans totaling $13.7 million and $27.3 million on loan payment deferral as of December 31, 2021 and June 30, 2021, respectively. 19

Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company utilizes the same grading process for acquired loans as it does for originated loans. The Company uses the following definitions for risk ratings: Special Mention - Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Substandard - Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful - Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above-described process and loans in groups of homogenous loans are considered to be pass rated loans.

Post-Retirement Benefits Employee Pension Plan The Company maintains a non-contributory defined benefit pension plan that covers employees meeting specific requirements as to age and length of service. The Company’s contributions to this qualified plan are determined on the basis of (i) the maximum amount that can be deducted for federal income tax purposes, and (ii) the amount determined by a consulting actuary as necessary to avoid an accumulated funding deficiency as defined by the Employee Retirement Income Security Act of 1974 (“ERISA”). Contributions are intended to provide for benefits attributed to service to date but also those expected to be earned in the future. On February 15, 2017, the Board of Directors approved the freezing of the defined benefit pension plan effective May 1, 2017. Supplemental Executive Retirement Plans The Company also maintains unfunded and non-qualified supplemental executive retirement plans ("SERP") to provide pension benefits in addition to those provided under the qualified pension plan. 22

Employee Stock Ownership Plan On January 1, 2017, the Company established an Employee Stock Ownership Plan (“ESOP”) to provide eligible employees the opportunity to own Company stock. The ESOP is a tax-qualified retirement plan for the benefit of Company employees. On April 20, 2017, the Holding Company granted a loan to the ESOP in the amount of $14.5 million for the purchase of 1,453,209 shares of the Company’s common stock at a price of $10.00 per share. The loan obtained by the ESOP from the Holding Company to purchase the common stock is payable annually over 15 years at a rate per annum equal to the Prime Rate, reset annually on January 1st (3.25% for 2021). Loan payments are principally funded by cash contributions from the Bank. The loan is secured by the shares purchased, which are held in a suspense account for allocation among participants as the loan is repaid. The balance of the ESOP loan at December 31, 2021 was $9.7 million. Contributions are allocated to eligible participants on the basis of compensation, subject to federal tax limits. The number of shares committed to be released annually is 96,881 through 2032. Dividends on allocated shares increase participant accounts and are used to purchase additional shares of stock. Participants receive the shares at the end of employment. Shares held by the ESOP include the following (dollars in thousands): December 31, 2021 June 30, 2021 Allocated to participants 469,127 417,902 Unearned 968,810 1,017,648 Total ESOP shares 1,437,937 1,435,550 Fair value of unearned shares $ 18,446 $ 18,491 Total compensation expense recognized in connection with the ESOP for the three and six months ended December 31, 2021 was $457,000 and $903,000, respectively, and for the three and six months ended December 31, 2020 was $360,000 and $661,000, respectively. 23

Note 7. Fair Value of Financial Instruments Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as general classification of such instruments pursuant to the valuation hierarchy, is set forth below. While management believes the Company’s valuation methodologies are appropriate and consistent with other financial institutions, 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. Investment Securities: The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs), matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs), or a broker's opinion of value (Level 3 inputs). Impaired Loans: The fair value of collateral-dependent impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. Appraisals are generally obtained annually and may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Management performs a review of all appraisals, including any such adjustments. The fair value of uncollateralized or non-collateral-dependent loans are generally based on discounted cash flows which utilize management’s assumption of discount rates and expected future cash flows, resulting in a Level 3 classification. Foreclosed Real Estate: Assets acquired through or instead of loan foreclosure are initially recorded at fair value, less estimated costs to sell, when acquired, establishing a new cost basis. These assets are subsequently accounted for at the lower of cost or fair value, less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Foreclosed properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Credit Department, as well as a third-party specialist, where deemed appropriate, reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Once appraisals are considered appropriate, management discounts the appraised value for estimated selling costs, such as legal, broker, and property maintenance and insurance costs. The most recent analysis performed indicated discount rates ranging between 10% and 20% should be applied to properties with appraisals performed. Derivatives: The Company’s derivative assets and liabilities consist of transactions undertaken as part of management’s strategy to manage interest rate risk. The valuation of the Company’s interest rate swaps is obtained 24

from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest rate curves. The Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy. Assets and liabilities measured at fair value are summarized below (in thousands): Fair Value Measurements Level 1 Level 2 Level 3 Total December 31, 2021 Measured on a recurring basis: Available for sale securities: U.S. Government and agency obligations $ - $ 10,730 $ - $ 10,730 Corporate - 5,032 3,135 8,167 State and municipal - 6,992 - 6,992 Mortgage-backed securities - residential - 15,284 - 15,284 Mortgage-backed securities - commercial - 2,514 - 2,514 Derivatives - interest rate contracts - 3,824 - 3,824 Total assets at fair value $ - $ 44,376 $ 3,135 $ 47,511 Derivatives - interest rate contracts $ - $ 3,824 $ - $ 3,824 Total liabilities at fair value $ - $ 3,824 $ - $ 3,824 Measured on a non-recurring basis: Impaired loans: Residential mortgages $ - $ - $ 309 $ 309 Home equity lines of credit - - 27 27 Total assets at fair value $ - $ - $ 336 $ 336 Fair Value Measurements Level 1 Level 2 Level 3 Total June 30, 2021 Measured on a recurring basis: Available for sale securities: U.S. Government and agency obligations $ - $ 21,816 $ - $ 21,816 Corporate - 5,058 3,131 8,189 State and municipal - 7,115 - 7,115 Mortgage-backed securities - residential - 17,654 - 17,654 Mortgage-backed securities - commercial - 2,613 - 2,613 Derivatives - interest rate contracts - 4,232 - 4,232 Total assets at fair value $ - $ 58,488 $ 3,131 $ 61,619 Derivatives - interest rate contracts $ - $ 4,232 $ - $ 4,232 Total liabilities at fair value $ - $ 4,232 $ - $ 4,232 Measured on a non-recurring basis: Impaired loans: Residential mortgages $ - $ - $ 312 $ 312 Home equity lines of credit - - 25 25 Total assets at fair value $ - $ - $ 337 $ 337 There were no transfers between levels within the fair value hierarchy during the three and six months ended December 31, 2021 and 2020. 25

Impaired loans in the preceding table had a carrying amount of $455,000 and a remaining valuation allowance of $119,000, at December 31, 2021, as compared to $471,000 and $125,000, respectively, as of June 30, 2021. Impaired loans measured at fair value incurred no net charge-offs and resulted in a credit for loan losses of $3,000 during the six months ended December 31, 2021. Impaired loans measured at fair value as of December 31, 2020 incurred no net charge-offs and resulted in a provision for loan losses of $2,000 during the six months ended December 31, 2020. The following tables present quantitative information about Level 3 fair value measurements for selected financial instruments measured at fair value on a non-recurring basis at December 31, 2021 and June 30, 2021 (dollars in thousands): Valuation Unobservable Range or Fair Value Technique(s) Input(s) Rate Used December 31, 2021 Impaired loans - residential mortgages $ 309 Discounted cash flow Discount rate 5.4% to 6.3% Impaired loans - home equity lines of credit 27 Discounted cash flow Discount rate 5.4% to 6.3% June 30, 2021 Impaired loans - residential mortgages $ 312 Discounted cash flow Discount rate 5.4% to 6.3% Impaired loans - home equity lines of credit 25 Discounted cash flow Discount rate 5.4% to 6.3% The following is a summary of the carrying amounts and estimated fair values of the Company’s financial assets and liabilities, none of which are held for trading purposes (in thousands): Carrying Fair Value Measurements Amount Level 1 Level 2 Level 3 Total December 31, 2021 Financial assets: Cash and cash equivalents $ 120,339 $ 120,339 $ - $ - $ 120,339 Investment securities held to maturity 390,312 - 354,962 34,852 389,814 Investment securities available for sale 43,687 - 40,552 3,135 43,687 Loans receivable, net 1,243,646 - - 1,243,799 1,243,799 Loans receivable held for sale 1,452 - - 1,452 1,452 Accrued interest receivable 6,509 - 1,648 4,861 6,509 FHLB stock 4,167 N/A N/A N/A N/A Derivative assets - interest rate contracts 3,824 - 3,824 - 3,824 Financial liabilities: Demand, NOW, money market deposits and savings accounts 1,168,711 1,168,711 - - 1,168,711 Time deposits 354,356 - 358,819 - 358,819 Mortgage escrow funds 10,880 10,880 - - 10,880 Accrued interest payable 127 1 126 - 127 FHLB advances 58,390 - 59,103 - 59,103 Derivative liabilities - interest rate contracts 3,824 - 3,824 - 3,824 26

Note 8. Regulatory Matters The following is a summary of the Bank’s actual capital amounts and ratios as of December 31, 2021 and June 30, 2021, compared to the required ratios for minimum capital adequacy and for classification as well capitalized (dollars in thousands). To Be Well Capitalized For Capital Under Prompt Adequacy Corrective Action Bank Actual Purposes Provisions Amount Ratio Amount Ratio Amount Ratio December 31, 2021 Leverage (Tier 1) $ 242,523 12.9% $ 75,115 4.0% $ 93,893 5.0% Risk-based: Common Tier 1 242,523 17.7 61,769 4.5 89,222 6.5 Tier 1 242,523 17.7 82,359 6.0 109,812 8.0 Total 250,952 18.3 109,812 8.0 137,265 10.0 June 30, 2021 Leverage (Tier 1) $ 233,944 12.5% $ 74,988 4.0% $ 93,735 5.0% Risk-based: Common Tier 1 233,944 17.9 58,713 4.5 84,807 6.5 Tier 1 233,944 17.9 78,283 6.0 104,378 8.0 Total 241,825 18.5 104,378 8.0 130,472 10.0 In addition to the ratios above, the Basel III Capital Rules have established that community banking institutions must maintain a capital conservation buffer of common equity Tier 1 capital in an amount greater than 2.5% of total risk-weighted assets to avoid being subject to limitations on capital distributions and discretionary bonus payments to executive officers. Management believes that as of December 31, 2021 and June 30, 2021, the Bank met all capital adequacy requirements to which it was subject, including the capital conservation buffer of 2.5%. Further, the most recent 27

FDIC notification categorized the Bank as a well-capitalized institution under the prompt corrective action regulations. There have been no conditions or events since that notification that management believes have changed the Bank’s capital classification. Note 9. Earnings Per Share (“EPS”) Basic EPS is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated in a similar matter, except that the denominator includes the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method. Dilutive financial instruments include stock options and unvested restricted stock. The following table provides factors used in the earnings per share computation. Three Months Ended December 31, Six Months Ended December 31, 2021 2020 2021 2020 (dollars in thousands, except per share data) Net income applicable to common stock $ 4,288 $ 2,694 $ 7,902 $ 5,422 Average number of common shares outstanding 15,217,484 15,966,158 15,280,230 16,184,821 Less: Average unallocated ESOP shares (981,011) (1,077,630) (993,221) (1,089,839) Average number of common shares outstanding used to calculate basic earnings per common share 14,236,473 14,888,528 14,287,009 15,094,982 Effect of equity-based awards 44,759 492 62,263 - Average number of common shares outstanding used to calculate diluted earnings per common share 14,281,232 14,889,020 14,349,272 15,094,982 Earnings per common share: Basic $ 0.30 $ 0.18 $ 0.55 $ 0.36 Diluted $ 0.30 $ 0.18 $ 0.55 $ 0.36 Stock options for 1,314,963 and 1,309,550 shares of common stock were not considered in computing diluted earnings per common share for the three and six months ended December 31, 2021, respectively, because they were antidilutive. Stock options for 1,345,293 and 1,343,695 shares of common stock were not considered in computing diluted earnings per common share for the three and six months ended December 31, 2020, respectively, because they were antidilutive. Note 10. Derivatives and Hedging Derivatives not designated as hedges may be used to manage the Company’s exposure to interest rate movements or to provide service to customers. The Company executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that the Company executes with a third party in order to minimize the net risk exposure resulting from such transactions. The Company presents interest rate swap assets and liabilities in other assets and other liabilities, respectively, in the Consolidated Balance Sheets. These interest rate swap agreements do not qualify for hedge accounting treatment, and therefore changes in fair value are reported in current period earnings. The following table presents summary information about the interest rate swaps as of December 31, 2021 and June 30, 2021 (dollars in thousands). 28

Revenue From Contracts With Customers In accordance with ASC 606, revenue is recognized when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these services. The Company applies the following five steps to properly recognize revenue: 1. Identify the contract with a customer. 2. Identify the performance obligations in the contract. 3. Determine the transaction price. 4. Allocate the transaction price to performance obligations in the contract. 5. Recognize revenue when (or as) the Company satisfies a performance obligation. The following table presents summary information about sources of revenue from contracts with customers for the periods indicated (in thousands). Three Months Ended December 31, Six Months Ended December 31, 2021 2020 2021 2020 Noninterest income: Service charges on deposits $ 199 $ 196 $ 382 $ 358 Interchange fees 164 133 320 264 Other fees and service charges (1) 44 34 106 63 Fees and service charges 407 363 808 685 Gain on sale of premises (1) 548 - 548 - Bank-owned life insurance (1) 191 129 383 261 Net gains on sales of loans receivable (1) 41 - 47 - Swap income (1) - 238 - 367 Other noninterest income (1) 8 13 22 24 Total noninterest income $ 1,195 $ 743 $ 1,808 $ 1,337 (1) Not within the scope of ASC 606. Fees and Service Charges on Deposit Accounts. The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payments, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of the month, representing the period over which the Company satisfied the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. Interchange Income. The Company earns interchange fees from debit cardholder transactions conducted through various payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. 29

Gain on Sales of Foreclosed Real Estate. The Company records a gain or loss from the sale of foreclosed real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of foreclosed real estate to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the foreclosed real estate asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. Note 12. Stock-Based Compensation On October 24, 2018, the Company’s shareholders approved the PCSB Financial Corporation 2018 Equity Incentive Plan (the “Plan”), which permits the grant of stock options and restricted stock and/or restricted stock units. The total number of shares that may be granted under the Plan is 2,543,115, of which 1,816,511 shares may be granted as stock options and 726,604 shares may be granted as restricted stock and restricted stock units. Total compensation cost that has been charged against income for the Plan was $820,000 and $1.6 million for the three and six months ended December 31, 2021 and $822,000 and $1.7 million for the three and six months ended December 31, 2020, respectively. Restricted Stock Awards (“RSAs”) RSAs awarded under the Plan provide for the issuance of shares to both employees and non-employee directors. These awards generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award. All awards were made at the fair value of common stock on the grant date. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at grant date. The fair value of the stock was determined to be the closing price of the stock on the NASDAQ exchange. Total shares available for grant under the Plan are 726,000, of which 549,467 shares were granted as of December 31, 2021. The following table presents a summary of RSA activity during the period ended December 31, 2021. Number of Shares Weighted-Average Grant Date Fair Value Unvested granted shares outstanding at July 1, 2021 322,580 $ 18.95 Shares granted 8,000 17.66 Shares vested (107,130) 18.97 Shares forfeited - - Unvested granted shares at December 31, 2021 223,450 $ 18.89 As of December 31, 2021, there was $3.9 million of total unrecognized compensation cost related to non-vested shares granted under the Plan. The cost is expected to be recognized over a weighted-average period of 2.2 years. Stock Option Awards Stock options awarded to employees under the Plan are considered incentive stock options (ISOs), up to applicable limits. Option awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. Those issued to non-employee directors, as well as those exceeding ISO limitations, are considered non-qualified stock options (NQSOs). Options generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award, however, may not vest more rapidly than over a three-year period, and have a contractual term of 10 years. The Company has a policy of using shares held as a treasury stock to satisfy share option exercises. Currently, the Company has a sufficient number of treasury shares to satisfy the current level of exercisable share options. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatilities of a peer group of publicly traded financial institutions. The expected term of options granted is based on the simplified “mid-point” approach which utilizes the weighted average vesting period and contractual 30

term. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. Total options available for grant under the Plan are 1,816,511, of which 1,320,963 options were granted as of December 31, 2021. The following table presents a summary of activity related to stock options granted under the Plan, and changes during the period then ended: Number of Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Years Aggregate Intrinsic Value (dollars in thousands, except per share data) Options outstanding at July 1, 2021 1,308,963 $ 19.00 7.4 $ 35 Options granted 12,000 17.66 Options expired - - Options forfeited - - Options exercised - - Options outstanding at December 31, 2021 1,320,963 $ 18.98 6.9 $ 389 Exercisable at December 31, 2021 782,978 $ 19.02 6.9 $ 207 As of December 31, 2021, there was $2.3 million of total unrecognized compensation cost related to non-vested stock options granted under the Plan. The cost is expected to be recognized over a weighted-average period of 2.2 years. The fair value of options granted during the six months ended December 31, 2021, was determined using the following weighted-average assumptions as of grant date. Risk-free interest rate 1.00% Expected term (in years) 6.25 Expected stock price volatility 35.91% Dividend yield 1.36% Weighted average fair value of options granted $ 5.50 Note 13. Leases As of December 31, 2021, the Company leases real estate for eleven branch offices and one administrative office, including its corporate headquarters, under various operating lease agreements. The Company’s leases have maturities which range from 2022 to 2041, some of which include lessee options to extend the lease term. The weighted average remaining life of the lease terms for these leases was 9.59 years as of December 31, 2021. The operating lease asset and lease liability are determined at the commencement date of the lease based on the present value of the lease payments. As most of our leases do not provide an implicit rate, the Company used its incremental borrowing rate, the rate of interest to borrow on a collateralized basis for a similar term, at the lease commencement date. The Company utilized a weighted average discount rate of 2.40% in determining the lease liability as of December 31, 2021. The Company made a policy election to exclude the recognition requirements of ASC 842 to short-term leases, those leases with original terms of 12 months or less. Short-term lease payments are recognized in the income statement on a straight-line basis over the lease term. The Company had no short-term lease cost for the three or six months ended December 31, 2021 or 2020. Certain leases may include one or more options to renew. The exercise of lease renewal options is typically at the Company’s discretion and are included in the operating lease liability if it is reasonably certain that the renewal option will be exercised. Certain real estate leases may contain lease and non-lease components, such as common area maintenance charges, real estate taxes, and insurance, which are generally accounted for separately and are not included in the measurement of the lease liability since they are generally able to be segregated. The Company does not sublease any of its leased properties. There were no sale and leaseback 31

transactions, leveraged leases or lease transactions with related parties during the three or six months ended December 31, 2021 or 2020. Total operating lease cost was $505,000 and $1.0 million for the three and six months ended December 31, 2021 and $501,000 and $1.0 million for the three and six months ended December 31, 2020, respectively. The right-of-use asset, included in premises and equipment, net, was $8.8 million and the corresponding lease liability, included in other liabilities was $9.0 million as of December 31, 2021. Future minimum lease payments for the fiscal years ending June 30 and a reconciliation of undiscounted lease cash flows and the lease liability recognized in the consolidated balance sheet as of December 31, 2021 is shown below: (dollars in thousands) 2022 $ 1,017 2023 1,940 2024 1,569 2025 1,276 2026 748 Thereafter 3,802 Total future minimum lease payments (undiscounted) 10,352 Discounting effect on cash flows (1,327) Lease liability (discounted) $ 9,025 Note 14. Subsequent Events Subsequent to December 31, 2021, and through February 2, 2022, the Company repurchased 3,122 shares of common stock, at an average cost of $19.02. 32

Loan Payment Deferrals The COVID-19 pandemic has created extensive disruptions to the local economy and our customers. Through December 31, 2021, the Company has granted loan payment deferrals on 330 consumer and commercial loans whose borrowers have demonstrated financial hardship caused by COVID-19 with loan balances totaling $220.2 million. As of December 31, 2021, 7 loans totaling $13.7 million were still on deferral. Of those loans still on deferral as of December 31, 2021, $10.1 million have resumed payments in January 2022, with the remaining $3.6 million (1 loan) scheduled to resume payments in June 2022. The table below provides additional detail for those loans on deferral as of December 31, 2021 (dollar amounts in thousands): 34

Industry Sector: Number of loans Recorded Investment (1) (2) % secured by real estate collateral Loan-to-Value % (3) Weighted average term of remaining deferral (in months) Consumer 1 $ 91 100.0% 23.2% 2.0 Commercial: Retail 3 11,590 100.0 59.6 1.6 Food service 1 1,696 100.0 44.9 0.0 All other commercial 2 369 50.1 38.9 0.0 Total commercial 6 13,655 98.7 57.4 1.3 Total 7 $ 13,746 98.7% 57.2% 1.4 (1) Includes loans classified as pass-rated, special mention and substandard of $8.3 million, $185,000 and $5.3 million, respectively. (2) Includes $3.6 million of nonaccrual loans. All loans are considered current. (3) Generally based on collateral values upon origination. The table below provides additional detail regarding the type of deferral granted for those loans on deferral as of December 31, 2021 (dollar amounts in thousands): Consumer Commercial Total Principal only $ - $ 8,378 $ 8,378 Principal and interest 91 5,277 5,368 Total $ 91 $ 13,655 $ 13,746 Comparison of Financial Condition at December 31, 2021 and June 30, 2021 Total Assets. Total assets increased $13.2 million, or 0.7%, to $1.89 billion at December 31, 2021 from $1.87 billion at June 30, 2021. The increase is primarily the result of increases of $52.7 million in held to maturity investment securities and $14.2 million in net loans receivable, partially offset by decreases of $39.0 million in cash and cash equivalents and $13.7 million in available for sale investment securities. Cash and Cash Equivalents. Cash and cash equivalents decreased $39.0 million, or 24.5%, to $120.3 million at December 31, 2021 from $159.3 million at June 30, 2021. The decrease is primarily due to a $39.0 million increase in total investment securities, a $14.2 million increase in net loans receivable, an $11.3 million decrease in other liabilities and a $7.6 million decrease in FHLB advances, partially offset by a $31.4 million increase in deposits. Securities Held to Maturity. Total securities held to maturity increased $52.7 million, or 15.6%, to $390.3 million at December 31, 2021 from $337.6 million at June 30, 2021. This increase was primarily due to increases of $29.9 million in municipal securities, $8.5 million in corporate bonds, $8.3 million in mortgage-backed securities, and $6.0 million in U.S. government and agency obligations. Securities Available for Sale. Total securities available for sale decreased $13.7 million, or 23.9%, to $43.7 million at December 31, 2021 from $57.4 million at June 30, 2021. This decrease was primarily due to decreases of $11.0 million in U.S. government and agency obligations, $2.2 million in mortgage-backed securities and a $430,000 decrease in net unrealized gains. Net Loans Receivable. Net loans receivable increased $14.2 million, or 1.2%, to $1.24 billion at December 31, 2021 from $1.23 billion at June 30, 2021. The increase in loans receivable was the result of a $41.0 million increase in commercial mortgages and a $1.7 million increase in construction loans, partially offset by decreases of $15.6 million in commercial loans, $11.5 million in residential mortgage loans and $1.3 million in home equity credit lines. The decrease in commercial loans includes a decrease of $24.3 million in PPP loans, driven by paydowns and forgiveness. 35

Deposits. Total deposits increased $31.4 million, or 2.1%, to $1.52 billion at December 31, 2021 as compared to $1.49 billion at June 30, 2021. This increase primarily reflects increases of $28.5 million in money market accounts, $21.4 million in NOW accounts and $5.5 million in savings accounts, partially offset by decreases of $20.7 million in time deposits and $3.3 million in demand deposits. Federal Home Loan Bank Advances. FHLB advances decreased $7.6 million to $58.4 million at December 31, 2021 as compared to $66.0 million at June 30, 2021. This decrease is due to maturities and principal paydowns of $7.6 million. Total Shareholder’s Equity. Total shareholders’ equity increased $274,000, or 0.1%, to $274.8 million at December 31, 2021 from $274.6 million at June 30, 2021. This increase was primarily due to net income of $7.9 million and $2.5 million of stock-based compensation and reduction in unearned ESOP shares for plan shares earned during the period, partially offset by the repurchase of $8.2 million (440,666 shares) of common stock and $1.7 million of cash dividends declared and paid. On February 3, 2021, a repurchase plan was authorized to repurchase up to 801,856 shares, or 5% of the Company’s then outstanding common stock. As of December 31, 2021, the Company repurchased 679,439 shares of common stock at an average cost of $18.23 per share under this plan. At December 31, 2021, the Bank was considered “well capitalized” under applicable regulatory guidelines. Comparison of Operating Results for the Three Months Ended December 31, 2021 and December 31, 2020 General. Net income increased $1.6 million, or 59.2%, to $4.3 million for the three months ended December 31, 2021 compared to $2.7 million for the same period last year. The increase was primarily due to a $1.7 million increase in net interest income and a $452,000 increase in noninterest income, partially offset by a $298,000 increase in income tax expense, a $157,000 increase in provision for loan losses and a $114,000 increase in non-interest expense. Net Interest Income. Net interest income increased $1.7 million, or 14.8%, to $13.3 million for the three months ended December 31, 2021 compared to $11.6 million for the same period last year. The increase primarily reflects an $81.6 million, or 4.8%, increase in average interest-earning assets and a 27 basis point increase in the tax equivalent net interest margin to 2.97% for the three months ended December 31, 2021 compared to 2.70% for the same period last year. The increase in average interest-earning assets reflects a $114.1 million increase in average investment securities and a $9.6 million increase in average loans receivable, partially offset by a $42.0 million decrease in average other interest-earning assets. Interest and Dividend Income. Interest and dividend income increased $645,000, or 4.5%, to $14.9 million for the three months ended December 31, 2021 compared to $14.2 million for the same period last year. The increase primarily reflects an $81.6 million increase in total average interest-earning assets and a 1 basis point increase in the yield on total interest-earning assets. The increase in the average interest earning assets is primarily due to higher average balances in investment securities and loans receivable. The increase in the average yield on interest earning assets is due to higher prepayment income and PPP loan interest income and origination fee income in the current year quarter, mostly offset by ongoing downward repricing of securities and loans. Interest income on loans receivable increased $469,000, or 3.8%, primarily due to a 12 basis point increase in the average tax equivalent yield on loans receivable to 4.07% for the three months ended December 31, 2021 from 3.95% for the same period last year and a $9.6 million, or 0.8%, increase in the average balance of loans receivable to $1.24 billion for the three months ended December 31, 2021 from $1.23 billion for the same period last year. The increase in the average tax equivalent yield on loans receivable is primarily due to $555,000 of prepayment income and $332,000 of PPP loan interest income and origination fee income recognized by the Company in the current year quarter compared to $73,000 and $159,000, respectively, for the same period last year. Interest income on investment securities increased $198,000, or 10.2%, primarily due to a $114.1 million increase in the average balance of investment securities to $427.9 million for the three months ended December 31, 2021 from $313.8 million for the same period last year, partially offset by a 43 basis point decrease in the average tax equivalent yield on investment securities to 2.08% for the three months ended December 31, 2021 from 2.51% for the same period last year. The increase in the average balance of investment securities is the result of the Company utilizing excess liquidity to fund securities portfolio growth and loan portfolio growth. The decrease in tax equivalent yield is a result of the investment portfolio continuing to re-price downward due to lower market interest rates and $117,000 in prepayment income recognized by the Company in the prior year. 36

Interest income on other interest-earning assets, primarily consisting of cash balances at correspondent banks including the Federal Reserve, decreased $22,000, or 20.0%, primarily due to a $42.0 million decrease in the average balance of other interest-earning assets to $126.6 million for the three months ended December 31, 2021 compared to $168.6 million for the same period last year, partially offset by a 2 basis point increase in the average yield on other interest-earning assets to 0.28% for the three months ended December 31, 2021, from 0.26% for the same period last year. The decrease in average balance of other interest earning assets is due to the Company utilizing funds to purchase investment securities and originate loans. Interest Expense. Interest expense decreased $1.1 million, or 39.8%, to $1.6 million for the three months ended December 31, 2021 compared to $2.7 million for the same period last year. The decrease primarily reflects a 34 basis point decrease in the average cost of interest-bearing liabilities to 0.47% for the three months ended December 31, 2021 from 0.81% for the same period last year, partially offset by a $59.2 million increase in the average balance of interest-bearing liabilities to $1.37 billion for the three months ended December 31, 2021 from $1.31 billion for the same period last year. Interest expense on interest-bearing deposits decreased $866,000, or 40.1%, primarily due to a 32 basis point decrease in the average cost of interest-bearing deposits to 0.39% for the three months ended December 31, 2021 from 0.71% for the same period last year and offset by a $101.4 million increase in the average balance to $1.30 billion for the three months ended December 31, 2021 from $1.20 billion for the same period last year. The decrease in the average rate paid on interest-bearing deposits was primarily caused by a decrease in market interest rates affecting most significantly the average rates paid on time deposits and money market accounts, which decreased 52 and 14 basis points, respectively, when compared to the same period last year. Over the next 12 months, the Company has $40.0 million of wholesale funding maturing, comprised of FHLB advances and brokered time deposits, with a weighted average cost of 2.07%. Interest expense on FHLB advances decreased $200,000, or 38.5%, primarily due to a $42.2 million decrease in the average balance to $63.8 million for the three months ended December 31, 2021 from $106.0 million for the same period last year, partially offset by a 5 basis point increase in the average cost to 1.99% for the three months ended December 31, 2021 from 1.94% for the same period last year. The increase in the cost of FHLB advances is due to the maturity of lower-costing advances. Provision for Loan Losses. The provision for loan losses was $264,000 for the three months ended December 31, 2021, compared to $107,000 for the same period last year. The increase is primarily due to loan portfolio growth. Recoveries, net of charge-offs, were $6,000 for the three months ended December 31, 2021 compared to charge-offs, net of recoveries, of $102,000 for the same period last year. Non-performing loans as a percent of total loans receivable (excluding PPP loans) were 0.64% as of December 31, 2021, an increase from 0.48% compared to June 30, 2021. The increase in non-performing loans over the last 12 months primarily includes three commercial relationships totaling $6.3 million, including $2.7 million of loans secured by multi-family commercial real estate (including 1 relationship consisting of 2 construction loans totaling $1.5 million) with a weighted average loan-to-value ratio of 68.8% and one loan for $3.6 million secured by non-owner-occupied retail commercial real estate with a loan-to-value ratio of 53.9%. Loans on a COVID-19 related payment deferral totaled $13.7 million, or 1.10% of gross loans, as of December 31, 2021, compared to $27.3 million, or 2.21% of gross loans, as of June 30, 2021. Loans on deferral totaling $10.1 million have resumed payments in January 2022, with the remaining $3.6 million (1 loan) scheduled to resume payments in June 2022. Noninterest Income. Noninterest income increased $452,000, or 60.8%, to $1.2 million for the three months ended December 31, 2021 compared to the same period last year. The increase was caused primarily by increases of $548,000 in gains on sale of premises, $62,000 in bank-owned life insurance income, $44,000 in fees and service charges and $41,000 in gains on sale of loans, partially offset by a $238,000 decrease in swap income and a $5,000 decrease in all other noninterest income. During the current quarter, the Company sold a parcel of unused land, resulting in the gain discussed above. The increase in fees and service charges compared to the same period last year was partially the result of the waiver in the prior year of certain overdraft fees, ATM usage fees, wire and CD early withdrawal fees in response to COVID-19, as well an increase in debit card and interchange income in the current year. Noninterest Expense. Noninterest expense increased $114,000, or 1.3%, for the three months ended December 31, 2021 compared to the same period last year. The increase was primarily due to increases of $323,000 in salaries and benefits, $80,000 in communication and data processing, $80,000 in franchise taxes (due to reinstitution of NYS capital tax) and $55,000 in all other noninterest expense, partially offset by decreases of 37

$341,000 in pension costs and $83,000 in professional fees. The increase in salaries and benefits was due to increases of $137,000 in ESOP and other post-retirement benefits and $186,000 in all other salaries and benefits. Income Tax Expense. Income tax expense increased $298,000, or 37.3%, for the three months ended December 31, 2021 compared to the same period last year. The increase was caused by higher pre-tax income, partially offset by a lower effective tax rate. The effective income tax rate was 20.4% for the three months ended December 31, 2021 as compared to 22.9% for the same period last year, with the decrease largely driven by an increase in tax-exempt interest income on municipal investments and bank-owned life insurance income. Comparison of Operating Results for the Six Months Ended December 31, 2021 and December 31, 2020 General. Net income increased $2.5 million, or 45.7%, to $7.9 million for the six months ended December 31, 2021 compared to $5.4 million for the same period last year. The increase was primarily due to a $2.7 million increase in net interest income and a $471,000 increase in noninterest income, partially offset by a $485,000 increase in income tax expense, a $114,000 increase in non-interest expense and a $61,000 increase in provision for loan losses. Net Interest Income. Net interest income increased $2.7 million, or 11.5%, to $25.8 million for the six months ended December 31, 2021 compared to $23.1 million for the same period last year. The increase primarily reflects a $72.2 million, or 4.2%, increase in average interest-earning assets and a 20 basis point increase in the tax equivalent net interest margin to 2.90% for the six months ended December 31, 2021 compared to 2.70% for the same period last year. The increase in average interest-earning assets reflects a $101.7 million increase in average investment securities, partially offset by a $9.8 million decrease in average loans receivable and a $19.7 million decrease in average other interest-earning assets. Interest and Dividend Income. Interest and dividend income increased $344,000, or 1.2%, to $29.1 million for the six months ended December 31, 2021 compared to $28.8 million for the same period last year. The increase primarily reflects a $72.2 million increase in total average interest-earning assets, partially offset by a 9 basis point decrease in the yield on total interest-earning assets. The increase in the average interest earning assets is primarily due to higher average balances in the investment securities portfolio. The decrease in the average tax equivalent yield on interest earning assets is the result of the investment securities and loan portfolios continuing to re-price downward due to lower market rates, partially offset by higher prepayment income and PPP loan interest income and origination fee income in the current year. Interest income on loans receivable increased $29,000, or 0.1%, primarily due to a 3 basis point increase in the average tax equivalent yield on loans receivable to 4.01% for the six months ended December 31, 2021 from 3.98% for the same period last year, partially offset by a $9.8 million, or 0.8%, decrease in the average balance of loans receivable to $1.23 billion for the six months ended December 31, 2021 from $1.24 billion for the same period last year. The increase in the average tax equivalent yield on loans receivable is primarily due to $587,000 of prepayment income and $705,000 of PPP loan interest income and origination fee income recognized by the Company in the current year period compared to $132,000 and $376,000, respectively, for the same period in the prior year. Interest income on investment securities increased $353,000, or 9.3%, primarily due to a $101.6 million increase in the average balance of investment securities to $416.2 million for the six months ended December 31, 2021 from $314.6 million for the same period last year, partially offset by a 36 basis point decrease in the average tax equivalent yield on investment securities to 2.08% for the six months ended December 31, 2021 from 2.44% for the same period last year. The increase in the average balance of investment securities is the result of the Company utilizing excess liquidity to fund investment securities portfolio growth and loan portfolio growth. The decrease in tax equivalent yield is a result of the investment portfolio continuing to re-price downward due to lower market interest rates and $117,000 in prepayment penalties recognized by the Company in the prior year period. Interest income on other interest-earning assets, primarily consisting of cash balances at correspondent banks including the Federal Reserve, decreased $38,000, or 16.2%, primarily due to a $19.7 million decrease in the average balance of other interest-earning assets to $143.6 million for the six months ended December 31, 2021 compared to $163.3 million for the same period last year and a 2 basis point decrease in the average yield on other interest-earning assets to 0.27% for the six months ended December 31, 2021, from 0.29% compared to the same period last year. The decrease in average balance of other interest earning assets is due to the Company utilizing 38

funds to purchase investment securities and originate loans. The decrease in the yield on other interest earning assets is primarily due to changes in asset mix. Interest Expense. Interest expense decreased $2.3 million, or 41.3%, to $3.3 million for the six months ended December 31, 2021 compared to $5.6 million for the same period last year. The decrease primarily reflects a 38 basis point decrease in the average cost of interest-bearing liabilities to 0.48% for the six months ended December 31, 2021 from 0.86% for the same period last year, partially offset by a $56.9 million increase in the average balance of interest-bearing liabilities to $1.37 billion for the six months ended December 31, 2021 from $1.31 billion for the same period last year. Interest expense on interest-bearing deposits decreased $1.9 million, or 42.4%, primarily due to a 36 basis point decrease in the average cost of interest-bearing deposits to 0.40% for the six months ended December 31, 2021 from 0.76% for the same period last year, partially offset by a $98.1 million increase in the average balance to $1.30 billion for the six months ended December 31, 2021 from $1.20 billion for the same period last year. In response to lower market interest rates and increased liquidity levels, deposit rate reductions have been implemented throughout the last two years, the effects of which continue to be realized. The decrease in market interest rates most significantly affected the average rates paid on time deposits and money market accounts, which decreased 58 and 15 basis points, respectively, when compared to the same period last year. Interest expense on FHLB advances decreased $381,000, or 36.7%, primarily due to a $41.2 million decrease in the average balance to $64.9 million for the six months ended December 31, 2021 from $106.1 million for the same period last year, partially offset by a 7 basis point increase in the average cost to 2.01% for the six months ended December 31, 2021 from 1.94% for the same period last year. The increase in the cost of FHLB advances is due to the maturity of lower-costing advances. Provision for Loan Losses. The provision for loan losses was $277,000 for the six months ended December 31, 2021, compared to $216,000 for the same period last year. The increase is primarily due to loan portfolio growth. Recoveries, net of charge-offs, were $271,000 for the six months ended December 31, 2021 compared to charge-offs, net of recoveries, of $178,000 for the same period last year. Noninterest Income. Noninterest income increased $471,000, or 35.2%, to $1.8 million for the six months ended December 31, 2021 compared to the same period last year. The increase was caused primarily by increases of $548,000 in gains on sale of premises, $123,000 in fees and service charges, $122,000 in bank-owned life insurance income and $47,000 in gains on sale of loans, partially offset by a $367,000 decrease in swap income and a $2,000 decrease in all other noninterest income. During the current year, the Company sold a parcel of unused land, resulting in the gain discussed above. The increase in fees and service charges compared to the same period last year was partially the result of the waiver in the prior year of certain overdraft fees, ATM usage fees, wire and CD early withdrawal fees in response to COVID-19, as well an increase in debit card and interchange income in the current year. Noninterest Expense. Noninterest expense increased $114,000, or 0.7%, for the six months ended December 31, 2021 compared to the same period last year. The increase was primarily due to increases of $489,000 in salaries and benefits, $159,000 in franchise taxes and $145,000 in all other noninterest expenses, partially offset by a $589,000 decrease in pension costs and a $90,000 decrease in professional fees. The increase in salaries and benefits was due to increases of $324,000 in ESOP and other post-retirement benefits and $175,000 in all other salaries and benefits. Income Tax Expense. Income tax expense increased $485,000, or 32.2%, for the six months ended December 31, 2021 compared to the same period last year. The increase was caused by higher pre-tax income, partially offset by a lower effective tax rate. The effective income tax rate was 20.1% for the six months ended December 31, 2021 compared to 21.8% for the same period last year, with the decrease largely driven by an increase in tax-exempt interest income on municipal investments and bank-owned life insurance income. 39

Average Balance Sheet and Interest Rates. The following table presents information regarding average balances of assets and liabilities, the total dollar amounts of interest income and dividends from average interest-earning assets, the total dollar amounts of interest expense on average interest-bearing liabilities, and the resulting annualized average tax equivalent yields and costs. The yields and costs for the periods indicated are derived by dividing income or expense by the average balances of assets or liabilities, respectively, for the periods presented. Average balances have been calculated using daily balances. Nonaccrual loans are included in average balances only. Loan fees are included in interest income on loans and are not material (dollars in thousands).

Rate/Volume Analysis. The following table sets forth the effects of changing rates and volumes on our net interest income. The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The net column represents the sum of the prior columns. Changes attributable to changes in both rate and volume that cannot be segregated have been allocated proportionally based on the changes due to rate and the changes due to volume (in thousands).

The majority of our assets and liabilities are monetary in nature. Consequently, our most significant form of market risk is interest rate risk. Our assets, consisting primarily of loans, have longer maturities than our liabilities, consisting primarily of deposits. As a result, a principal part of our business strategy is to manage our exposure to changes in market interest rates. Accordingly, we have established a management-level Asset/Liability Management Committee, which takes initial responsibility for developing an asset/liability management process and related procedures, establishing and monitoring reporting systems and developing asset/liability strategies. On at least a quarterly basis, the Asset/Liability Management Committee reviews asset/liability management with the 42

Investment Asset/Liability Committee of the Board of Directors. This Committee also reviews any changes in strategies as well as the performance of any specific asset/liability management actions that have been implemented previously. On a quarterly basis, an outside consulting firm provides us with detailed information and analysis as to asset/liability management, including our interest rate risk profile. Ultimate responsibility for effective asset/liability management rests with our Board of Directors. We have sought to manage our interest rate risk in order to minimize the exposure of our earnings and capital to changes in interest rates. We have implemented the following strategies to manage our interest rate risk: originating loans with adjustable interest rates; utilizing interest rate swaps, promoting core deposit products; and adjusting the interest rates and maturities of funding sources, as necessary. By following these strategies, we believe that we are better positioned to react to changes in market interest rates. Net Portfolio Value Simulation. We analyze our sensitivity to changes in interest rates through a net portfolio value of equity (“NPV”) model. NPV represents the present value of the expected cash flows from our assets less the present value of the expected cash flows arising from our liabilities. The NPV ratio represents the dollar amount of our NPV divided by the present value of our total assets for a given interest rate scenario. NPV attempts to quantify our economic value using a discounted cash flow methodology while the NPV ratio reflects that value as a form of equity ratio. We estimate what our NPV would be at a specific date. We then calculate what the NPV would be at the same date throughout a series of interest rate scenarios representing immediate and permanent, parallel shifts in the yield curve. We currently calculate NPV under the assumptions that interest rates increase 100 and 200 basis points from current market rates and that interest rates decrease 50 and 100 basis points from current market rates. The following table presents the estimated changes in our NPV that would result from changes in market interest rates at December 31, 2021 and June 30, 2021. All estimated changes presented in the table are within the policy limits approved by our Board of Directors (dollars in thousands). NPV NPV as Percent of Portfolio Value of Assets Basis Point Change in Interest Rates Dollar Amount Dollar Change Percent Change NPV Ratio Change (in bps) December 31, 2021: 200 $ 272,628 $ (38,768) (12.4) % 15.40% (129) 100 298,428 (12,968) (4.2) 16.39 (30) - 311,396 - - 16.70 - (50) 331,242 19,846 6.4 17.49 79 (100) 355,886 44,490 14.3 18.50 181 June 30, 2021: 200 $ 270,679 $ (37,814) (12.3) % 15.21% (122) 100 291,715 (16,778) (5.4) 15.95 (48) - 308,493 - - 16.43 - (50) 324,999 16,506 5.4 17.06 63 (100) 346,539 38,046 12.3 17.94 151 Certain shortcomings are inherent in the methodologies used in the above interest rate risk measurements. Modeling changes require making certain assumptions that may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. The above table assumes that the composition of our interest-sensitive assets and liabilities existing at the date indicated remains constant uniformly across the yield curve regardless of the duration or repricing of specific assets and liabilities. Accordingly, although the table provides an indication of our interest rate risk exposure at a particular point in time, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates on our NPV and will differ from actual results. 43

Liquidity and Capital Resources Liquidity. Liquidity is the ability to meet current and future financial obligations of a short-term nature. Our primary sources of funds consist of deposit inflows, loan repayments and maturities and sales of securities. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows and mortgage prepayments are greatly influenced by general interest rates, economic conditions and competition. We regularly review the need to adjust our investments in liquid assets based upon our assessment of: (1) expected loan demand, (2) expected deposit flows, (3) yields available on interest-earning deposits and securities, and (4) the objectives of our asset/liability management program. Excess liquid assets are invested generally in interest-earning deposits and short- and intermediate-term securities. Our most liquid assets are cash and cash equivalents. The levels of these assets are dependent on our operating, financing, lending and investing activities during any given period. At December 31, 2021, cash and cash equivalents totaled $120.3 million, a decrease from $159.3 million as of June 30, 2021. Unpledged securities classified as available for sale, which provide an additional source of liquidity, totaled $24.0 million at December 31, 2021, a decrease from $28.9 million as of June 30, 2021. We had the ability to borrow up to $372.2 million from the FHLB of New York, at December 31, 2021 of which $58.4 million was outstanding as of December 31, 2021. Additionally, as of December 31, 2021, we had an available line of credit with the FRB of New York’s discount window program of $97.3 million, and $25.0 million of fed funds lines of credit, neither of which had outstanding balances as of December 31, 2021. We have no material commitments or demands that are likely to affect our liquidity other than as set forth below. If loan demand was to increase faster than expected, or any unforeseen demand or commitment was to occur, we could access our borrowing sources detailed above. We had $42.1 million of loan commitments outstanding as of December 31, 2021 and $163.6 million of approved, but unadvanced, funds to borrowers. We also had $3.1 million in outstanding letters of credit at December 31, 2021. Time deposits due within one year of December 31, 2021 totaled $212.6 million. If these deposits do not remain with us, we will be required to seek other sources of funds, including other time deposits and FHLB of New York advances. Depending on market conditions, we may be required to pay higher rates on such deposits or other borrowings than we currently pay on the time deposits at December 31, 2021. We believe, however, based on past experience that a significant portion of our time deposits will remain with us. We have the ability to attract and retain deposits by adjusting the interest rates offered. The Holding Company is a separate legal entity from the Bank and must provide for its own liquidity to pay any dividends to its shareholders, to repurchase shares of its common stock and for other corporate purposes. The Holding Company’s primary source of liquidity is dividend payments it may receive from the Bank. The Bank’s ability to pay dividends to the Holding Company is governed by applicable law and regulations. At December 31, 2021, the Holding Company (on an unconsolidated, stand-alone basis) had liquid assets of $19.7 million. Capital Resources. The Bank is subject to various regulatory capital requirements administered by the NYSDFS and the FDIC. At December 31, 2021, the Bank exceeded all applicable regulatory capital requirements, and the Bank was considered “well capitalized” under applicable regulatory 2021, the Bank exceeded all applicable regulatory capital requirements, and the Bank was considered “well capitalized” under applicable regulatory guidelines.

PCSB Financial Corporation and Subsidiaries Notes to Consolidated Financial Statements (unaudited) Note 1. Basis of Presentation Nature of Operations: PCSB Financial Corporation (the “Holding Company” and together with its direct and indirect subsidiaries, the “Company”) is a Maryland corporation organized by PCSB Bank (the “Bank”) for the purpose of acquiring all of the capital stock of the Bank issued in the Bank's conversion to stock ownership on April 20, 2017. At September 30, 2022, the significant assets of the Holding Company were the capital stock of the Bank, cash deposited in the Bank, and a loan to the PCSB Bank Employee Stock Ownership Plan (“ESOP”). The liabilities of the Holding Company were insignificant. The Company is subject to the financial reporting requirements of the Securities Exchange Act of 1934, as amended, and regulation and examination by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) and the New York State Department of Financial Services (the “NYSDFS”). PCSB Bank is a community-oriented financial institution that provides financial services to individuals and businesses within its market area of Putnam, Southern Dutchess, Rockland and Westchester Counties in New York. The Bank is a state-chartered commercial bank, and its deposits are insured up to applicable limits by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”). The Bank’s primary regulators are the FDIC and the NYSDFS. Basis of Presentation: The unaudited consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), and include the accounts of the Holding Company, the Bank and the Bank's two subsidiaries – PCSB Funding Corp. and UpCounty Realty Corp. (formerly PCSB Realty Ltd.). PCSB Funding Corp. is a real estate investment trust that holds certain mortgage assets. UpCounty Realty Corp. is a corporation that holds certain properties foreclosed upon by the Bank. All intercompany transactions and balances have been eliminated in consolidation. The unaudited consolidated financial statements contained herein reflect all normal recurring adjustments that are, in the opinion of management, necessary for a fair presentation of the results for the interim periods presented. Such adjustments are the only adjustments reflected in the consolidated financial statements contained herein. The results of operations for the current period presented are not necessarily indicative of the results of operations that may be expected for the entire current fiscal year. Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission. The accompanying unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the fiscal year ended June 30, 2022, included in the Company's Annual Report on Form 10-K for the fiscal year ended June 30, 2022. Certain prior period amounts have been reclassified to conform to the current presentation. Reclassifications had no effect on prior period net income or equity. Risks and Uncertainties: In preparing these consolidated financial statements, management is required to make significant estimates and assumptions that affect the reported amounts of assets, liabilities, income, expenses and disclosure of contingent assets and liabilities. Actual results could differ from those estimates based upon changing conditions, including economic conditions and future events, such as continued interest rate volatility, prolonged periods of inflation, continued trade and supply chain disruptions, economic recession and increased unemployment. Such conditions could cause the Company to experience a material adverse effect on our business operations, asset valuations, financial condition, and results of operations. Material adverse impacts may include, but are not limited to, the valuation impairments of the Company’s intangible assets, investments, loans receivable, or deferred tax assets. Additionally, it is reasonably possible that the Company’s allowance for loan loss estimate as of September 30, 2022 could change in the near term and could result in a material change to the Company’s provision for loan losses, earnings and capital. Use of Estimates: To prepare financial statements in conformity with GAAP management makes estimates and assumptions based on available information. These estimates and assumptions affect the amounts reported in the financial statements and the disclosures provided, and actual results could differ. 8

Note 2. Recent Accounting Pronouncements The pronouncements discussed below are not intended to be an all-inclusive list, but rather only those pronouncements that the Company has determined could potentially have a material impact on its consolidated financial position and results of operations or on its disclosures. There were no accounting standards adopted in the current period. Future Application of Accounting Pronouncements Previously Issued In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU 2016-13 “Measurement of Credit Losses on Financial Instruments.” ASU 2016-13 which affects entities holding financial assets that are not accounted for at fair value through net income, including loans, debt securities, and other financial assets. The ASU requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected by recording an allowance for current expected credit losses. In October 2019, the FASB unanimously voted to delay the implementation of the standard for three years for certain companies, including small reporting companies (as defined by the SEC), non-SEC public companies and private companies. The Company currently qualifies as a small reporting company and is subject to the delayed implementation. Therefore, the amendments in this update will be effective for the Company for the fiscal year beginning on July 1, 2023, including interim periods within that fiscal year. The Company is actively working through the provisions of the Update. Management has established a steering committee which is identifying the methodologies and the additional data requirements necessary to implement the Update and has engaged a third-party software service provider to assist in the Company's implementation. On March 31, 2022 the FASB issued ASU 2022-02 "Financial Instruments - Credit Losses (Topic 326), Troubled Debt Restructurings and Vintage Disclosures." The ASU eliminates the current accounting guidance on troubled debt restructurings ("TDRs") for creditors, enhances disclosures for creditors with respect to loan refinancings and restructurings for borrowers experiencing financial difficulty and amends the guidance on vintage disclosures with respect to current period gross charge-offs. For entities that have not yet adopted ASU 2016-13, the amendments in ASU 2022-02 are effective upon the adoption of ASU 2016-13. Management is currently evaluating the impact that ASU 2016-13 and ASU 2022-02 will have on the Company’s consolidated financial position, results of operations and disclosures. The FASB issued ASU 2020-04 “Reference Rate Reform” and ASU 2021-01 “Reference Rate Reform Scope” which collectively address accounting considerations related to the expected discontinuation of LIBOR as a reference rate for financial contracts. These Updates provide optional expedients and exceptions for applying generally accepted accounting principles to contracts, hedging relationships and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform (codified in ASC 848). They include optional expedients related to contract modifications that allow an entity to account for modifications (if certain criteria are met) as if the modifications were only minor (assets within the scope of ASC 310, Receivables), were not substantial (assets within the scope of ASC 470, Debt) and/or did not result in remeasurements or reclassifications (assets within the scope of ASC 842, Leases, and other Topics) of the existing contract. They also include optional expedients and exceptions for contract modifications and hedge accounting that apply to derivative instruments impacted by the market-wide discounting transition. The Updates also allow for a one-time election to sell, transfer, or both sell and transfer debt securities classified as held to maturity that reference a rate affected by reference rate reform and that are classified as held to maturity before January 1, 2020. The guidance in these ASUs are effective as of March 12, 2020 through December 31, 2022. The Company has not yet elected to apply the practical expedients contained in these Updates and does not expect significant impact to the consolidated financial statements upon adoption. 9

Non-U.S. government and agency obligations are internally pass rated and are subject to quarterly credit monitoring. There were no securities for which the Company believes it is not probable that it will collect all amounts due according to the contractual terms of the security as of September 30, 2022 or June 30, 2022. Management believes the unrealized losses are primarily a result of changes in market interest rates. The Company has determined that it does not intend to sell, or it is not more likely than not that it will be required to sell, its securities that are in an unrealized loss position prior to the recovery of its amortized cost basis. Therefore, the Company did not consider any securities to be other-than-temporarily impaired as of September 30, 2022 or June 30, 2022. Note 4.

Such loans are excluded because the loans are in pools that are considered performing. The discounts arising from recording these loans at fair value upon acquisition were due in part to credit quality and the accretable yield is being recognized as interest income over the life of the loans based on expected cash flows. 15

The modification of the terms of such loans included one or a combination of the following: a reduction of the stated interest rate of the loan; an extension of the maturity date at a stated rate of interest lower than the current market rate for new debt with similar risk; or a permanent reduction of the recorded investment in the loan. All TDRs are considered impaired loans. As of both September 30, 2022 and June 30, 2022, the Company had 9 loans, classified as TDRs totaling $1.4 million, including $1.2 million of loans still accruing interest. The Company has allocated $111,000 and $119,000, respectively, of specific reserves to customers whose loan terms have been modified in TDRs as of September 30, 2022 and June 30, 2022. As of September 30, 2022, the Company has no commitments to lend additional funds to customers with outstanding loans that are classified as TDRs. The Company did not modify any loans during the three months ended September 30, 2022 or 2021 that were classified as TDRs. There were no defaults of TDRs occurring in the three months ended September 30, 2022 or 2021 that were modified in the twelve months prior to default. In order to determine whether a borrower is experiencing financial difficulty, an evaluation is performed of the probability that the borrower will be in payment default on any of its debt in the foreseeable future without the modification. This evaluation is performed under the Company’s internal underwriting policy. On March 27, 2020, the Coronavirus Aid, Relief, and Economic Security Act (“CARES Act”) was signed into law. Section 4013 of the CARES Act, “Temporary Relief From Troubled Debt Restructurings,” provides banks the option to temporarily suspend certain requirements under U.S. GAAP related to TDRs for a limited period of time to account for the effects of COVID-19. On December 27, 2020, the Consolidated Appropriations Act 2021 was signed into law. Section 541 of this legislation, “Extension of Temporary Relief From Troubled Debt Restructurings and Insurer Clarification,” extends Section 4013 of the CARES Act to the earlier of January 1, 2022 or 60 days after the termination of the national emergency declared relating to COVID-19. This extension expired as of January 1, 2022. Additionally, on April 7, 2020, the banking agencies, including the Board of Governors of the Federal Reserve System and the Federal Deposit Insurance Corporation, issued a statement, “Interagency Statement on Loan Modifications and Reporting for Financial Institutions Working With Customers Affected by the Coronavirus (Revised)” (“Interagency Statement”), to encourage banks to work prudently with borrowers 16

and to describe the agencies’ interpretation of how accounting rules under ASC 310-40, “Troubled Debt Restructurings by Creditors,” apply to certain COVID-19-related modifications. During the three months ended September 30, 2022, no loan payment deferrals were granted or extended by the Company. During the three months ended September 30, 2021, the Company granted or extended loan payment deferrals for 5 residential mortgage, construction and commercial loans totaling $3.7 million. In accordance with either the CARES Act (as amended) or Interagency Statement, these modifications are not considered TDRs. The Company had no loans on loan payment deferral as of September 30, 2022 nor June 30, 2022. Credit Quality Indicators The Company categorizes loans into risk categories based on relevant information about the ability of borrowers to service their debt such as: current financial information, historical payment experience, credit documentation, public information, and current economic trends, among other factors. The Company analyzes loans individually by classifying the loans as to credit risk. This analysis includes non-homogeneous loans, such as commercial and commercial real estate loans. This analysis is performed on a monthly basis. The Company utilizes the same grading process for acquired loans as it does for originated loans. The Company uses the following definitions for risk ratings: Special Mention – Loans classified as special mention have a potential weakness that deserves management's close attention. If left uncorrected, these potential weaknesses may result in deterioration of the repayment prospects for the loan or of the institution's credit position at some future date. Substandard – Loans classified as substandard are inadequately protected by the current net worth and paying capacity of the obligor or of the collateral pledged, if any. Loans so classified have a well-defined weakness or weaknesses that jeopardize the liquidation of the debt. They are characterized by the distinct possibility that the institution will sustain some loss if the deficiencies are not corrected. Doubtful – Loans classified as doubtful have all the weaknesses inherent in those classified as substandard, with the added characteristic that the weaknesses make collection or liquidation in full, on the basis of currently existing facts, conditions, and values, highly questionable and improbable. Loans not meeting the criteria above that are analyzed individually as part of the above-described process and loans in groups of homogenous loans are considered to be pass rated loans. These loans are monitored based on delinquency and performance. Based on the most recent analysis performed, the risk category of loans by portfolio segment is as follows (in thousands): September 30, 2022 Pass Special Mention Substandard Total Residential mortgages $ 213,581 $ 383 $ 622 $ 214,586 Commercial mortgages 944,482 1,538 7,519 953,539 Construction 22,515 1,679 1,113 25,307 Commercial loans 141,295 145 462 141,902 Home equity lines of credit 22,587 - 368 22,955 Consumer and overdrafts 508 - - 508 Total $ 1,344,968 $ 3,745 $ 10,084 $ 1,358,797 June 30, 2022 Pass Special Mention Substandard Total Residential mortgages $ 212,810 $ 154 $ 1,203 $ 214,167 Commercial mortgages 931,178 1,548 9,404 942,130 Construction 18,104 1,679 1,113 20,896 Commercial loans 135,725 156 423 136,304 Home equity lines of credit 23,220 43 425 23,688 Consumer and overdrafts 594 - - 594 Total $ 1,321,631 $ 3,580 $ 12,568 $ 1,337,779 17

Purchased Credit Impaired Loans The Company has acquired loans for which there was, at acquisition, evidence of deterioration of credit quality since origination and it was probable, at acquisition, that all contractually required payments would not be collected.

Note 6. Post-Retirement Benefits Employee Pension Plan The Company maintains a non-contributory defined benefit pension plan that covers employees meeting specific requirements as to age and length of service. The Company’s contributions to this qualified plan are determined on the basis of (i) the maximum amount that can be deducted for federal income tax purposes, and (ii) the amount determined by a consulting actuary as necessary to avoid an accumulated funding deficiency as defined by the Employee Retirement Income Security Act of 1974 (“ERISA”). Contributions are intended to provide for benefits attributed to service to date but also those expected to be earned in the future. On February 15, 2017, the Board of Directors approved the freezing of the defined benefit pension plan effective May 1, 2017. Supplemental Executive Retirement Plans The Company also maintains unfunded and non-qualified supplemental executive retirement plans ("SERP") to provide pension benefits in addition to those provided under the qualified pension plan. Net periodic benefit cost and other amounts recognized in other comprehensive income for the three months ended September 30, 2022 and 2021 (in thousands): Three Months Ended Three Months Ended September 30, 2022 September 30, 2021 Defined Benefit Plan Supplemental Retirement Plans Defined Benefit Plan Supplemental Retirement Plans Service cost $ - $ 82 $ - $ 131 Interest cost 196 26 149 17 Expected return on plan assets (410 ) - (510 ) - Amortization of prior net loss 141 20 38 16 Settlement charges - - - - Net periodic (benefit) cost $ (73 ) $ 128 $ (323 ) $ 164 The Company made no contributions to the defined benefit plan during the three months ended September 30, 2022. Employee Stock Ownership Plan On January 1, 2017, the Company established an Employee Stock Ownership Plan (“ESOP”) to provide eligible employees the opportunity to own Company stock. The ESOP is a tax-qualified retirement plan for the benefit of Company employees. On April 20, 2017, the Holding Company granted a loan to the ESOP in the amount of $14.5 million for the purchase of 1,453,209 shares of the Company’s common stock at a price of $10.00 per share. The loan obtained by the ESOP from the Holding Company to purchase the common stock is payable annually over 15 years at a rate per annum equal to the Prime Rate, reset annually on January 1st (3.25% for 2022). Loan payments are principally funded by cash contributions from the Bank. The loan is secured by the shares purchased, which are held in a suspense account for allocation among participants as the loan is repaid. The balance of the ESOP loan at September 30, 2022 was $9.7 million. Contributions are allocated to eligible participants on the basis of compensation, subject to federal tax limits. The number of shares committed to be released annually is 96,881 through 2032. Dividends on allocated shares increase participant accounts and are used to purchase additional shares of stock. Participants receive the shares at the end of employment. Shares held by the ESOP include the following (Dollars in thousands): September 30, 2022 June 30, 2022 Allocated to participants 541,097 518,371 Unearned 896,348 920,767 Total ESOP shares 1,437,445 1,439,138 Fair value of unearned shares $ 16,072 $ 17,577 Total compensation expense recognized in connection with the ESOP for the three months ended September 30, 2022 and 2021 was $467,000 and $446,000, respectively. 19

Note 7. Fair Value of Financial Instruments Fair value is the exchange price that would be received for an asset or paid to transfer a liability (exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. There are three levels of inputs that may be used to measure fair values: Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the entity has the ability to access as of the measurement date. Level 2: Significant other observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data. Level 3: Significant unobservable inputs that reflect a reporting entity’s own assumptions about the assumptions that market participants would use in pricing an asset or liability. A description of the valuation methodologies used for assets and liabilities measured at fair value, as well as general classification of such instruments pursuant to the valuation hierarchy, is set forth below. While management believes the Company’s valuation methodologies are appropriate and consistent with other financial institutions, 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. Investment Securities: The fair values of securities available for sale are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs), matrix pricing, which is a mathematical technique widely used in the industry to value debt securities without relying exclusively on quoted prices for the specific securities but rather by relying on the securities’ relationship to other benchmark quoted securities (Level 2 inputs), or a broker's opinion of value (Level 3 inputs). Impaired Loans: The fair value of collateral-dependent impaired loans with specific allocations of the allowance for loan losses is generally based on recent real estate appraisals. Appraisals are generally obtained annually and may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are typically significant and result in a Level 3 classification of the inputs for determining fair value. Management performs a review of all appraisals, including any such adjustments. The fair value of uncollateralized or non-collateral-dependent loans are generally based on discounted cash flows which utilize management’s assumption of discount rates and expected future cash flows, resulting in a Level 3 classification. Foreclosed Real Estate: Assets acquired through or instead of loan foreclosure are initially recorded at fair value, less estimated costs to sell, when acquired, establishing a new cost basis. These assets are subsequently accounted for at the lower of cost or fair value, less estimated costs to sell. Fair value is commonly based on recent real estate appraisals which are updated no less frequently than annually. These appraisals may utilize a single valuation approach or a combination of approaches including comparable sales and the income approach. Adjustments are routinely made in the appraisal process by the independent appraisers to adjust for differences between the comparable sales and income data available. Such adjustments are usually significant and typically result in a Level 3 classification of the inputs for determining fair value. Foreclosed properties are evaluated on a quarterly basis for additional impairment and adjusted accordingly. Appraisals for both collateral-dependent impaired loans and real estate owned are performed by certified general appraisers (for commercial properties) or certified residential appraisers (for residential properties) whose qualifications and licenses have been reviewed and verified by the Company. Once received, a member of the Credit Department, as well as a third-party specialist, where deemed appropriate, reviews the assumptions and approaches utilized in the appraisal as well as the overall resulting fair value in comparison with independent data sources such as recent market data or industry-wide statistics. Once appraisals are considered appropriate, management discounts the appraised value for estimated selling costs, such as legal, broker, and property maintenance and insurance costs. The most recent analysis performed indicated discount rates ranging between 10% and 20% should be applied to properties with appraisals performed. Derivatives: The Company’s derivative assets and liabilities consist of transactions undertaken as part of management’s strategy to manage interest rate risk. The valuation of the Company’s interest rate swaps is obtained from a third-party pricing service and is determined using a discounted cash flow analysis on the expected cash flows of each derivative. The pricing analysis is based on observable inputs for the contractual terms of the derivatives, including the period to maturity and interest 20

rate curves. The Company has determined that the majority of the inputs used to value its interest rate derivatives fall within Level 2 of the fair value hierarchy. Assets and liabilities measured at fair value are summarized below (in thousands): Fair Value Measurements Level 1 Level 2 Level 3 Total September 30, 2022 Measured on a recurring basis: Available for sale debt securities: U.S. Government and agency obligations $ - $ 9,443 $ - $ 9,443 Corporate - 1,997 2,768 4,765 State and municipal - 4,334 - 4,334 Mortgage-backed securities – residential - 11,623 - 11,623 Mortgage-backed securities – commercial - 2,266 - 2,266 Derivatives – interest rate contracts - 14,774 - 14,774 Total assets at fair value $ - $ 44,437 $ 2,768 $ 47,205 Derivatives – interest rate contracts $ - $ 14,774 $ - $ 14,774 Total liabilities at fair value $ - $ 14,774 $ - $ 14,774 Measured on a non-recurring basis: Impaired loans: Residential mortgages $ - $ - $ 242 $ 242 Home equity lines of credit - - 22 22 Total assets at fair value $ - $ - $ 264 $ 264 Fair Value Measurements Level 1 Level 2 Level 3 Total June 30, 2022 Measured on a recurring basis: Available for sale debt securities: U.S. Government and agency obligations $ - $ 9,928 $ - $ 9,928 Corporate - 2,004 2,850 4,854 State and municipal - 4,796 - 4,796 Mortgage-backed securities – residential - 12,712 - 12,712 Mortgage-backed securities – commercial - 2,331 - 2,331 Derivatives – interest rate contracts - 8,223 - 8,223 Total assets at fair value $ - $ 39,994 $ 2,850 $ 42,844 Derivatives – interest rate contracts $ - $ 8,223 $ - $ 8,223 Total liabilities at fair value $ - $ 8,223 $ - $ 8,223 Measured on a non-recurring basis: Impaired loans: Residential mortgages $ - $ - $ 306 $ 306 Home equity lines of credit - - 44 44 Total assets at fair value $ - $ - $ 350 $ 350 There were no transfers between levels within the fair value hierarchy during the three months ended September 30, 2022 or 2021. Impaired loans in the preceding table had a carrying amount of $375,000 and a remaining valuation allowance of $111,000, at September 30, 2022, as compared to $469,000 and $119,000, respectively, as of June 30, 2022. Impaired loans measured at fair value incurred no net charge-offs and resulted in a benefit for loan losses of $2,000 during the three months ended September 30, 2022. Impaired loans measured at fair value as of September 30, 2021 incurred no net charge-offs and resulted in a credit for loan losses of $2,000 during the three months ended September 30, 2021. 21

Note 8. Regulatory Matters The following is a summary of the Bank’s actual capital amounts and ratios as of September 30, 2022 and June 30, 2022, compared to the required ratios for minimum capital adequacy and for classification as well capitalized (Dollars in thousands). To Be Well Capitalized For Capital Under Prompt Adequacy Corrective Action Bank Actual Purposes Provisions Amount Ratio Amount Ratio Amount Ratio September 30, 2022 Leverage (Tier 1) $ 256,469 13.0 % $ 78,658 4.0 % $ 98,323 5.0 % Risk-based: Common Tier 1 256,469 17.3 66,842 4.5 96,549 6.5 Tier 1 256,469 17.3 89,122 6.0 118,829 8.0 Total 265,517 17.9 118,829 8.0 148,537 10.0 June 30, 2022 Leverage (Tier 1) $ 251,144 12.8 % $ 78,490 4.0 % $ 98,112 5.0 % Risk-based: Common Tier 1 251,144 17.2 65,630 4.5 94,799 6.5 Tier 1 251,144 17.2 87,507 6.0 116,676 8.0 Total 260,071 17.8 116,676 8.0 145,845 10.0 In addition to the ratios above, the Basel III Capital Rules have established that community banking institutions must maintain a capital conservation buffer of common equity Tier 1 capital in an amount greater than 2.5% of total risk-weighted assets to avoid being subject to limitations on capital distributions and discretionary bonus payments to executive officers. Management believes that as of September 30, 2022 and June 30, 2022, the Bank met all capital adequacy requirements to which it was subject, including the capital conservation buffer. Further, the most recent FDIC notification categorized the Bank as a well-capitalized institution under the prompt corrective action regulations. There have been no conditions or events since that notification that management believes have changed the Bank’s capital classification. Note 9. Earnings Per Share (“EPS”) Basic EPS is calculated by dividing net income available to common shareholders by the weighted average number of common shares outstanding during the period. Diluted EPS is calculated in a similar matter, except that the denominator includes the number of additional common shares that would have been outstanding if potentially dilutive common shares were issued using the treasury stock method. Dilutive financial instruments include stock options and unvested restricted stock. The following table provides factors used in the earnings per share computation for the three months ended September 30, 2022 and 2021: 2022 2021 (Dollars in thousands, except per share data) Net income applicable to common stock $ 4,776 $ 3,614 Average number of common shares outstanding 15,122,732 15,342,975 Less: Average unallocated ESOP shares (908,419 ) (1,005,432 ) Average number of common shares outstanding used to calculate basic earnings per common share 14,214,313 14,337,543 Effect of equity-based awards 87,287 68,273 Average number of common shares outstanding used to calculate diluted earnings per common share 14,301,600 14,405,816 Earnings per common share: Basic $ 0.34 $ 0.25 Diluted $ 0.33 $ 0.25 Stock options for 1,314,963 and 1,325,935 shares of common stock were not considered in computing diluted earnings per common share for the three months ended September 30, 2022 and 2021, respectively, because they were antidilutive. 23

Note 10. Derivatives and Hedging Derivatives not designated as hedges may be used to manage the Company’s exposure to interest rate movements or to provide service to customers. The Company executes interest rate swaps with commercial lending customers to facilitate their respective risk management strategies. These interest rate swaps with customers are simultaneously offset by interest rate swaps that the Company executes with a third party in order to minimize the net risk exposure resulting from such transactions. The Company presents interest rate swap assets and liabilities in other assets and other liabilities, respectively, in the Consolidated Balance Sheets. These interest rate swap agreements do not qualify for hedge accounting treatment, and therefore changes in fair value are reported in current period earnings. The following table presents summary information about the interest rate swaps as of September 30, 2022 and June 30, 2022 (Dollars in thousands). September 30, 2022 June 30, 2022 Notional amounts $ 287,485 $ 264,462 Weighted average pay rates 4.31 % 3.57 % Weighted average receive rates 4.31 % 3.57 % Weighted average maturity 8.14 years 8.22 years Fair value of combined interest rate swaps $ - $ - Note 11. Revenue From Contracts With Customers In accordance with ASC 606, revenue is recognized when a customer obtains control of promised services. The amount of revenue recognized reflects the consideration to which the Company expects to be entitled to receive in exchange for these services. The Company applies the following five steps to properly recognize revenue: 1. Identify the contract with a customer. 2. Identify the performance obligations in the contract. 3. Determine the transaction price. 4. Allocate the transaction price to performance obligations in the contract. 5. Recognize revenue when (or as) the Company satisfies a performance obligation. The following table presents summary information about sources of revenue from contracts with customers for the periods indicated (in thousands). Three months ended September 30, 2022 2021 Noninterest income: Service charges on deposits $ 234 $ 183 Interchange fees 153 156 Other fees and service charges 66 62 Fees and service charges 453 401 Swap income 141 - Bank-owned life insurance 191 192 Other noninterest income 8 20 Total noninterest income $ 793 $ 613 Not within the scope of ASC 606. Fees and Service Charges on Deposit Accounts. The Company earns fees from its deposit customers for transaction-based, account maintenance, and overdraft services. Transaction-based fees, which include services such as ATM use fees, stop payments, statement rendering, and ACH fees, are recognized at the time the transaction is executed as that is the point in time the Company fulfills the customer’s request. Account maintenance fees, which relate primarily to monthly maintenance, are earned over the course of the month, representing the period over which the Company satisfied the performance obligation. Overdraft fees are recognized at the point in time that the overdraft occurs. Service charges on deposits are withdrawn from the customer’s account balance. 24 (1) (1) (1) (1) (1)

Interchange Income. The Company earns interchange fees from debit cardholder transactions conducted through various payment networks. Interchange fees from cardholder transactions represent a percentage of the underlying transaction value and are recognized daily, concurrently with the transaction processing services provided to the cardholder. Gain on Sales of Foreclosed Real Estate. The Company records a gain or loss from the sale of foreclosed real estate when control of the property transfers to the buyer, which generally occurs at the time of an executed deed. When the Company finances the sale of foreclosed real estate to the buyer, the Company assesses whether the buyer is committed to perform their obligations under the contract and whether collectability of the transaction price is probable. Once these criteria are met, the foreclosed real estate asset is derecognized and the gain or loss on sale is recorded upon the transfer of control of the property to the buyer. In determining the gain or loss on the sale, the Company adjusts the transaction price and related gain (loss) on sale if a significant financing component is present. Note 12. Stock-Based Compensation On October 24, 2018, the Company’s shareholders approved the PCSB Financial Corporation 2018 Equity Incentive Plan (the “Plan”), which permits the grant of stock options and restricted stock and/or restricted stock units. The total number of shares that may be granted under the Plan is 2,543,115, of which 1,816,511 shares may be granted as stock options and 726,604 shares may be granted as restricted stock and restricted stock units. Total compensation cost that has been charged against income for the Plan was $820,000 and $810,000 for the three months ended September 30, 2022 and 2021, respectively. Restricted Stock Awards (“RSAs”) RSAs awarded under the Plan provide for the issuance of shares to both employees and non-employee directors. These awards generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award. All awards were made at the fair value of common stock on the grant date. Compensation expense is recognized over the vesting period of the awards based on the fair value of the stock at grant date. The fair value of the stock was determined to be the closing price of the stock on the NASDAQ exchange. Total shares available for grant under the Plan are 726,000, of which 549,467 shares were granted as of September 30, 2022. The following table presents a summary of RSA activity during the period ended September 30, 2022. Number of Shares Weighted-Average Grant Date Fair Value Unvested granted shares outstanding at July 1, 2022 223,450 $ 18.89 Shares granted - - Shares vested (2,200 ) 16.21 Shares forfeited - - Unvested granted shares at September 30, 2022 221,250 $ 18.92 As of September 30, 2022, there was $2.4 million of total unrecognized compensation cost related to non-vested shares granted under the Plan. The cost is expected to be recognized over a weighted-average period of 1.4 years. Stock Option Awards Stock options awarded to employees under the Plan are considered incentive stock options (ISOs), up to applicable limits. Option awards are generally granted with an exercise price equal to the market price of the Company’s common stock at the date of grant. Those issued to non-employee directors, as well as those exceeding ISO limitations, are considered non-qualified stock options (NQSOs). Options generally vest over a 5-year period, with 20% vesting each year on the anniversary of the award, however, may not vest more rapidly than over a three-year period, and have a contractual term of 10 years. The Company has a policy of using shares held as a treasury stock to satisfy share option exercises. Currently, the Company has a sufficient number of treasury shares to satisfy the current level of exercisable share options. The fair value of each option award is estimated on the date of grant using a closed form option valuation (Black-Scholes) model that uses the assumptions noted in the following table. Expected volatilities are based on the historical volatilities of a peer group of publicly traded financial institutions. The expected term of options granted is based on the simplified 25

“mid-point” approach which utilizes the weighted average vesting period and contractual term. The risk-free interest rate for the expected term of the option is based on the U.S. Treasury yield curve in effect at the time of the grant. Total options available for grant under the Plan are 1,816,511, of which 1,320,963 options were granted as of September 30, 2022. The following table presents a summary of activity related to stock options granted under the Plan, and changes during the period then ended: Number of Options Weighted-Average Exercise Price Weighted-Average Remaining Contractual Years Aggregate Intrinsic Value (Dollars in thousands, except per share data) Options outstanding at July 1, 2022 1,320,963 $ 18.98 6.4 $ 411 Options granted - - Options expired - - Options forfeited - - Options exercised - - Options outstanding at September 30, 2022 1,320,963 $ 18.98 6.1 $ 37 Exercisable at September 30, 2022 786,578 $ 19.00 6.1 $ 14 As of September 30, 2022, there was $1.4 million of total unrecognized compensation cost related to non-vested stock options granted under the Plan. The cost is expected to be recognized over a weighted-average period of 1.4 years. Note 13. Leases As of September 30, 2022, the Company leases real estate for eleven branch offices and one administrative office, including its corporate headquarters, under various operating lease agreements. The Company’s leases have maturities which range from 2023 to 2041, some of which include lessee options to extend the lease term. The weighted average remaining life of the lease terms for these leases was 9.4 years as of September 30, 2022. The operating lease asset and lease liability are determined at the commencement date of the lease based on the present value of the lease payments. As most of our leases do not provide an implicit rate, the Company used its incremental borrowing rate, the rate of interest to borrow on a collateralized basis for a similar term, at the lease commencement date. The Company utilized a weighted average discount rate of 2.49% in determining the lease liability as of September 30, 2022. The Company made a policy election to exclude the recognition requirements of ASC 842 to short-term leases, those leases with original terms of 12 months or less. Short-term lease payments are recognized in the income statement on a straight-line basis over the lease term. The Company had no short-term lease cost for the three months ended September 30, 2022 or 2021. Certain leases may include one or more options to renew. The exercise of lease renewal options is typically at the Company’s discretion and are included in the operating lease liability if it is reasonably certain that the renewal option will be exercised. Certain real estate leases may contain lease and non-lease components, such as common area maintenance charges, real estate taxes, and insurance, which are generally accounted for separately and are not included in the measurement of the lease liability since they are generally able to be segregated. The Company does not sublease any of its leased properties. There were no sale and leaseback transactions, leveraged leases or lease transactions with related parties during the three months ended September 30, 2022 or 2021. Total operating lease cost was $505,000 for the three months ended September 30, 2022 and 2021, respectively. The right-of-use asset, included in premises and equipment, net, was $8.1 million and the corresponding lease liability, included in other liabilities was $8.4 million as of September 30, 2022. Future minimum lease payments for the fiscal years ending June 30th and a reconciliation of undiscounted lease cash flows and the lease liability recognized in the consolidated balance sheet as of September 30, 2022 is shown below (in thousands): 26

Pending Merger With and Into Brookline Bancorp, Inc. On May 23, 2022, the Company and Brookline Bancorp, Inc (“Brookline”), the holding company of Brookline Bank and Bank Rhode Island, entered into an Agreement and Plan of Merger (the “Merger Agreement”). Pursuant to the Merger Agreement, the Company will merge with and into Brookline, with Brookline as the surviving corporation (the “Merger”). Following the Merger, PCSB Bank will operate as a separate bank subsidiary of Brookline. Pursuant to the terms of the Merger Agreement, at the effective time of the Merger, each stockholder of PCSB will receive, at the holder’s election, either $ 22.00 in cash consideration or 1.3284 shares of Brookline common stock for each share of PCSB common stock, subject to allocation procedures to ensure that 60% of the outstanding shares of PCSB common stock will be converted to Brookline common stock. On September 21, 2022, the Company's shareholders approved the Merger Agreement. The consummation of the Merger remains subject to customary closing conditions, including the receipt of regulatory approvals. The Merger is currently expected to be completed in the fourth calendar quarter of 2022. For the three months ended September 30, 2022, the Company recognized $311,000 of merger-related expenses. No merger-related expenses were recognized for the three months ended September 30, 2021. 27

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations. General Management’s discussion and analysis of financial condition at September 30, 2022 and June 30, 2022, and results of operations for the three months ended September 30, 2022 and 2021 is intended to assist in understanding the consolidated financial condition and results of operations of the Company.

Critical Accounting Policies and Critical Accounting Estimates Critical accounting estimates are necessary in the application of certain accounting policies and procedures and are particularly susceptible to significant change. Critical accounting policies are defined as those involving significant judgments, estimates and assumptions by management that could have a material impact on the carrying value of certain assets or on income under different assumptions or conditions. For additional information regarding critical accounting policies, refer to the section captioned “Critical Accounting Policies” in Management’s Discussion and Analysis of Financial Condition and Results of Operations included in the June 30, 2022 Form 10-K. There have been no significant changes in our application of critical accounting policies for the three months ended September 30, 2022. Overview PCSB Financial Corporation (the “Holding Company” and together with its direct and indirect subsidiaries, the “Company”) is a Maryland corporation organized by PCSB Bank (the “Bank”) for the purpose of acquiring all of the capital stock of the Bank issued in the Bank's conversion to stock ownership on April 20, 2017. At September 30, 2022, the significant assets of the Holding Company were the capital stock of the Bank, cash deposited in the Bank, and a loan to the PCSB Bank Employee Stock Ownership Plan (“ESOP”). The liabilities of the Holding Company were insignificant. The Company is subject to the financial reporting requirements of the Securities Exchange Act of 1934, as amended, and regulation and examination by the Board of Governors of the Federal Reserve System (the “Federal Reserve Board”) and the New York State Department of Financial Services (the “NYSDFS”). PCSB Bank is a community-oriented financial institution that provides financial services to individuals and businesses within its market area of Putnam, Southern Dutchess, Rockland and Westchester Counties in New York. The Bank is a state-chartered commercial bank, and its deposits are insured up to applicable limits by the Deposit Insurance Fund of the Federal Deposit Insurance Corporation (“FDIC”). The Bank’s primary regulators are the FDIC and the NYSDFS. The Company's primary market area encompasses all of Putnam and Westchester Counties and parts of Dutchess and Rockland Counties in New York, which are the counties in which our offices are located, and the surrounding areas. It is considered a primary area for growth, particularly for commercial lending and deposit opportunities. Westchester County includes a high concentration of office, medical, retail, industrial, mixed use and multi-family real estate buildings and businesses. Our primary focus in this marketplace is small to middle market businesses in these segments. Rising real estate values and lack of available commercial space in Brooklyn and Manhattan have caused businesses to migrate to central and lower Westchester County, which has increased the demand for flex-industrial and multi-family property loans in our market area. Dutchess, Putnam and Rockland Counties offer similar commercial opportunities to Westchester County, but on a significantly smaller scale, and provide greater opportunities in residential mortgage lending and consumer lending and in retail deposit gathering. The close proximity of Bronx County, New York City, Fairfield County, Connecticut, and Bergen County, New Jersey, to our market area also creates a secondary area of opportunity for office, industrial and multi-family property loans. 29

Non-GAAP Financial Measures The following table is a reconciliations of book value per share (GAAP measure) to tangible book value per share (non-GAAP measure) (Dollars in thousands, except share and per share data). As of September 30, 2022 June 30, 2022 Computation of Tangible Book Value per Common Share Total shareholders' equity (GAAP) $ 281,137 $ 277,162 Adjustments: Goodwill (6,106 ) (6,106 ) Other intangible assets (77 ) (89 ) Tangible common shareholders' equity (Non-GAAP) $ 274,954 $ 270,967 Common shares outstanding 15,334,323 15,334,857 Book value per share (GAAP) $ 18.33 $ 18.07 Adjustments: Effects of intangible assets (0.40 ) (0.40 ) Tangible book value per common share (Non-GAAP) $ 17.93 $ 17.67 Financial Condition Cash and Cash Equivalents. Cash and cash equivalents decreased $67.7 million, or 57.2%, to $50.8 million at September 30, 2022 from $118.5 million at June 30, 2022. The decrease is primarily due to a $33.0 million decrease in deposits, a $20.8 million increase in net loans receivable, and a $20.0 million decrease in FHLB advances, partially offset by an $8.4 million decrease in total investment securities. Investment Securities Portfolio. The following table is a summary of the Company's investment securities portfolio, at carrying value, as of September 30, 2022 and June 30, 2022 (Dollars in thousands): September 30, June 30, Increase / (Decrease) 2022 2022 $ % Available for sale debt securities U.S. Government and agency obligations $ 9,443 $ 9,928 $ (485 ) -4.9 % Corporate 4,765 4,854 (89 ) -1.8 State and municipal 4,334 4,796 (462 ) -9.6 Mortgage-backed securities – residential 11,623 12,712 (1,089 ) -8.6 Mortgage-backed securities – commercial 2,266 2,331 (65 ) -2.8 Total available for sale debt securities $ 32,431 $ 34,621 $ (2,190 ) -6.3 % Held to maturity debt securities U.S. Government and agency obligations $ 59,995 $ 59,995 $ - 0.0 % Corporate 52,068 52,076 (8 ) 0.0 State and municipal 88,490 87,111 1,379 1.6 Mortgage-backed securities – residential 97,886 101,525 (3,639 ) -3.6 Mortgage-backed securities – collateralized mortgage obligations 22,916 24,198 (1,282 ) -5.3 Mortgage-backed securities – commercial 84,895 87,544 (2,649 ) -3.0 Total held to maturity debt securities $ 406,250 $ 412,449 $ (6,199 ) -1.5 % The decrease in investment securities was primarily the result of principal payments in mortgage-backed securities. Loans Receivable Portfolio. The following table is a summary of the Company's loan portfolio, as of September 30, 2022 and June 30, 2022 (Dollars in thousands): 31

September 30, June 30, Increase / (Decrease) 2022 2022 $ % Mortgage loans Residential $ 214,586 $ 214,167 $ 419 0.2 % Commercial 953,539 942,130 11,409 1.2 Construction 25,307 20,896 4,411 21.1 Net deferred loan origination (fees) costs (145 ) (100 ) (45 ) 45.0 Total mortgage loans 1,193,287 1,177,093 16,194 1.4 Commercial and consumer loans: Commercial loans 141,902 136,304 5,598 4.1 Home equity lines of credit 22,955 23,688 (733 ) -3.1 Consumer and overdrafts 508 594 (86 ) -14.5 Net deferred loan origination costs (fees) 593 620 (27 ) -4.4 Total commercial and consumer loans 165,958 161,206 4,752 2.9 Total loans receivable 1,359,245 1,338,299 20,946 1.6 Allowance for loan losses (9,048 ) (8,927 ) (121 ) 1.4 Loans receivable, net $ 1,350,197 $ 1,329,372 $ 20,825 1.6 % Allowance for Loan Losses. The allowance for loan losses is maintained at a level considered adequate by management to provide for probable incurred loan losses inherent in the loan portfolio at the consolidated balance sheet reporting dates. The allowance for loan losses is based on management’s assessment of various factors affecting the loan portfolio, including portfolio composition, delinquent and non-accrual loans, national and local business conditions, loss experience and an overall evaluation of the quality of the underlying collateral. The allowance for loan losses increased $121,000, or 1.4%, to $9.0 million at September 30, 2022 from $8.9 million at June 30, 2022. The increase is primarily due to loan portfolio growth. Non-performing loans as a percent of total loans receivable were 0.59% as of September 30, 2022, a decrease from 0.69% as of June 30, 2022. Deposits. Deposits have traditionally been our primary source of funds for our lending and investment activities. The substantial majority of our deposits are from depositors who reside in our primary market area. Deposits are attracted through the offering of a broad selection of deposit instruments for both individuals and businesses. The following table is a summary of the Company's deposits, as of September 30, 2022 and June 30, 2022 (Dollars in thousands): September 30, June 30, Increase / (Decrease) 2022 2022 $ % Demand $ 227,635 $ 245,297 $ (17,662 ) -7.2 % NOW accounts 253,857 243,006 10,851 4.5 Money market accounts 385,470 399,026 (13,556 ) -3.4 Savings 402,980 411,332 (8,352 ) -2.0 Time deposits 323,324 327,589 (4,265 ) -1.3 Total deposits $ 1,593,266 $ 1,626,250 $ (32,984 ) -2.0 % Federal Home Loan Bank Advances. FHLB advances decreased $20.0 million, or 41.5%, to $28.3 million at September 30, 2022 as compared to $48.3 million at June 30, 2022. This decrease is due to maturities and principal paydowns. Total Shareholders’ Equity. Total shareholders’ equity increased $3.9 million, or 1.4%, to $281.1 million at September 30, 2022 from $277.2 million at June 30, 2022. This increase was primarily due to net income of $4.8 million and $1.3 million of stock-based compensation and reduction in unearned ESOP shares for plan shares earned during the period, partially offset by $1.1 million of other comprehensive losses related primarily to unrealized losses on available for sale investment securities driven by higher market interest rates and $1.0 million of cash dividends declared and paid. We would expect that further increases in market interest rates would lead to additional unrealized losses on available for sale investment securities. At September 30, 2022, the Bank was considered “well capitalized” under applicable regulatory guidelines. 32

Results of Operations for the Three Months Ended September 30, 2022 and September 30, 2021 Net Income. Net income increased $1.2 million, or 32.2%, to $4.8 million for the three months ended September 30, 2022 compared to $3.6 million for the three months ended September 30, 2021. The increase was primarily due to increases of $2.3 million in net interest income and $180,000 in noninterest income, partially offset by increases of $933,000 in noninterest expense, $338,000 in income tax expense and $69,000 in provision for loan losses. Net Interest Income. The following tables present information regarding average balances of assets and liabilities, the total dollar amounts of interest income and dividends from average interest-earning assets, the total dollar amounts of interest expense on average interest-bearing liabilities, and the resulting annualized average tax equivalent yields and costs. The yields and costs for the periods indicated are derived by dividing income or expense by the average balances of assets or liabilities, respectively, for the periods presented. Average balances have been calculated using daily balances. Nonaccrual loans are included in average balances only. Loan fees are included in interest income on loans and are not material (Dollars in thousands). Three Months Ended September 30, 2022 2021 Average Balance Interest/ Dividends Average Rate Average Balance Interest/ Dividends Average Rate Assets: Loans receivable $ 1,346,194 $ 13,849 4.12 % $ 1,223,532 $ 12,107 3.96 % Investment securities 445,231 2,420 2.26 404,565 2,011 2.07 Other interest-earning assets 85,377 487 2.26 160,659 109 0.27 Total interest-earning assets 1,876,802 16,756 3.59 1,788,756 14,227 3.20 Non-interest-earning assets 78,342 76,375 Total assets $ 1,955,144 $ 1,865,131 Liabilities and equity: NOW accounts $ 243,354 250 0.41 $ 182,531 70 0.15 Money market accounts 390,619 376 0.38 350,575 186 0.21 Savings accounts and escrow 422,178 186 0.18 397,292 113 0.11 Time deposits 323,219 852 1.05 367,641 985 1.06 Total interest-bearing deposits 1,379,370 1,664 0.48 1,298,039 1,354 0.41 FHLB advances 46,522 235 2.00 65,935 338 2.03 Total interest-bearing liabilities 1,425,892 1,899 0.53 1,363,974 1,692 0.49 Non-interest-bearing deposits 230,076 207,806 Other non-interest-bearing liabilities 22,180 19,943 Total liabilities 1,678,148 1,591,723 Total shareholders' equity 276,996 273,408 Total liabilities and shareholders' equity $ 1,955,144 $ 1,865,131 Net interest income $ 14,857 $ 12,535 Interest rate spread - tax equivalent 3.06 2.71 Net interest margin - tax equivalent 3.19 2.82 Average interest-earning assets to interest-bearing liabilities 131.62 % 131.14 % Tax exempt yield is shown on a tax equivalent basis for proper comparison using statutory federal income tax rate of 21% for all periods presented. See reconciliation of GAAP to non-GAAP measures in the table below. Net interest rate spread represents the difference between the average yield on average interest-earning assets and the average cost of average interest-bearing liabilities. Net interest margin represents annualized net interest income divided by average interest-earning assets.

The following table presents information regarding tax equivalent adjustment used in the calculation of certain financial metrics (Dollars in thousands). Three Months Ended September 30, 2022 2022 Total interest income $ 16,756 $ 14,227 Total interest expense 1,899 1,692 Net interest income (GAAP) 14,857 12,535 Tax equivalent adjustment 116 89 Net interest income - tax equivalent (non-GAAP) $ 14,973 $ 12,624 Rate/Volume Analysis. The following table sets forth the effects of changing rates and volumes on our net interest income. The rate column shows the effects attributable to changes in rate (changes in rate multiplied by prior volume). The volume column shows the effects attributable to changes in volume (changes in volume multiplied by prior rate). The net column represents the sum of the prior columns. Changes attributable to changes in both rate and volume that cannot be segregated have been allocated proportionally based on the changes due to rate and the changes due to volume (Dollars in thousands). Three Months Ended September 30, 2022 versus 2022 Rate Volume Net Interest income: Loans receivable $ 440 $ 1,302 $ 1,742 Investment securities 224 185 409 Other interest-earning assets 452 (74 ) 378 Total interest-earning assets 1,116 1,413 2,529 Interest expense: NOW accounts 150 30 180 Money market accounts 166 24 190 Savings and escrow accounts 66 7 73 Time deposits (16 ) (117 ) (133 ) FHLB advances (5 ) (98 ) (103 ) Total interest-bearing liabilities 361 (154 ) 207 Net increase in net interest income $ 755 $ 1,567 $ 2,322 Provision for Loan Losses. The provision for loan losses increased for the three months ended September 30, 2022, compared to the same period last year. The increase is primarily due to higher loan portfolio growth in the current period. Recoveries net of charge-offs were $39,000 for the three months ended September 30, 2022, compared to recoveries, net of charge-offs of $265,000 for the same period last year. Noninterest Income. The following table displays noninterest income for the three months ended September 30, 2022 and 2021 (Dollars in thousands). Three Months Ended September 30, Net Change 2022 2021 $ % Fees and service charges $ 453 $ 401 $ 52 13.0 % Bank-owned life insurance 191 192 (1 ) -0.5 % Swap income 141 - 141 100.0 % Other 8 20 (12 ) -60.0 % Total noninterest income $ 793 $ 613 $ 180 29.4 % The increase in fees and service charges for the three months ended September 30, 2022 compared to the same period last year was primarily the result of increases in deposit and loan processing fees. 34

Noninterest Expense. The following table displays noninterest expense for the three months ended September 30, 2022 and 2021 (Dollars in thousands). Three Months Ended September 30, Net Change 2022 2021 $ % Salaries and employee benefits $ 5,985 $ 5,773 $ 212 3.7 % Occupancy and equipment 1,403 1,353 50 3.7 % Communication and data processing 610 527 83 15.7 % Professional fees 335 393 (58 ) -14.8 % Merger-related expenses 311 - 311 100.0 % Postage, printing, stationery and supplies 174 143 31 21.7 % Advertising 128 100 28 28.0 % FDIC assessment 125 125 - 0.0 % Amortization of intangible assets 12 16 (4 ) -25.0 % Other operating expenses 474 194 280 144.3 % Total noninterest expense $ 9,557 $ 8,624 $ 933 10.8 % The increase in salaries and employee benefits for the three months ended September 30, 2022 compared to the same period last year is primarily driven by higher salary and benefit costs. Merger-related expenses associated with the pending Brookline Bancorp merger largely include professional services fees. The increase in other operating expenses for the three months ended September 30, 2022 compared to the same period last year is primarily due to higher pension costs in the current period. Income Tax Expense. The effective income tax rate was 20.5% for the three months ended September 30, 2022 as compared to 19.9% for the same period last year. Management of Market Risk General. The majority of our assets and liabilities are monetary in nature. Consequently, our most significant form of market risk is interest rate risk. Our assets, consisting primarily of loans, have longer maturities than our liabilities, consisting primarily of deposits. As a result, a principal part of our business strategy is to manage our exposure to changes in market interest rates. Accordingly, we have established a management-level Asset/Liability Management Committee, which takes initial responsibility for developing an asset/liability management process and related procedures, establishing and monitoring reporting systems and developing asset/liability strategies. On at least a quarterly basis, the Asset/Liability Management Committee reviews asset/liability management with the Investment Asset/Liability Committee of the Board of Directors. This Committee also reviews any changes in strategies as well as the performance of any specific asset/liability management actions that have been implemented previously. On a quarterly basis, an outside consulting firm provides us with detailed information and analysis as to asset/liability management, including our interest rate risk profile. Ultimate responsibility for effective asset/liability management rests with our Board of Directors. We have sought to manage our interest rate risk in order to minimize the exposure of our earnings and capital to changes in interest rates. We have implemented the following strategies to manage our interest rate risk: originating loans with adjustable interest rates; utilizing interest rate swaps, promoting core deposit products; and adjusting the interest rates and maturities of funding sources, as necessary. By following these strategies, we believe that we are better positioned to react to changes in market interest rates. Net Portfolio Value Simulation. We analyze our sensitivity to changes in interest rates through a net portfolio value of equity (“NPV”) model. NPV represents the present value of the expected cash flows from our assets less the present value of the expected cash flows arising from our liabilities. The NPV ratio represents the dollar amount of our NPV divided by the present value of our total assets for a given interest rate scenario. NPV attempts to quantify our economic value using a discounted cash flow methodology while the NPV ratio reflects that value as a form of equity ratio. We estimate what our NPV would be at a specific date. We then calculate what the NPV would be at the same date throughout a series of interest rate scenarios representing immediate and permanent, parallel shifts in the yield curve. We currently calculate NPV under the assumptions that interest rates increase 100 and 200 basis points from current market rates and that interest rates decrease 50 and 100 basis points from current market rates. 35

The following table presents the estimated changes in our NPV that would result from changes in market interest rates at September 30, 2022 and June 30, 2022 (Dollars in thousands). All estimated changes presented in the table are within the policy limits approved by our Board of Directors. NPV NPV as Percent of Portfolio Value of Assets Basis Point Change in Interest Rates Dollar Amount Dollar Change Percent Change NPV Ratio Change (in bps) September 30, 2022: 200 $ 256,664 $ (47,850 ) (15.7 % ) 15.06 % (188 ) 100 281,394 (23,120 ) (7.6 ) 16.07 (87 ) - 304,514 - - 16.94 - (100) 335,857 31,343 10.3 18.09 115 (200) 366,247 61,733 20.3 19.10 216 June 30, 2022: 200 $ 267,563 $ (50,616 ) (19.9 % ) 14.94 % (187 ) 100 294,042 (24,137 ) (7.6 ) 15.96 (85 ) - 318,179 - - 16.81 - (100) 349,957 31,778 10.0 17.90 109 (200) 382,642 64,463 20.3 18.96 215 Certain shortcomings are inherent in the methodologies used in the above interest rate risk measurements. Modeling changes require making certain assumptions that may or may not reflect the manner in which actual yields and costs respond to changes in market interest rates. The above table assumes that the composition of our interest-sensitive assets and liabilities existing at the date indicated remains constant uniformly across the yield curve regardless of the duration or repricing of specific assets and liabilities. Accordingly, although the table provides an indication of our interest rate risk exposure at a particular point in time, such measurements are not intended to and do not provide a precise forecast of the effect of changes in market interest rates on our NPV and will differ from actual results. Liquidity and Capital Resources Liquidity. Liquidity is the ability to meet current and future financial obligations of a short-term nature. Our primary sources of funds consist of deposit inflows, loan repayments and maturities and sales of securities. While maturities and scheduled amortization of loans and securities are predictable sources of funds, deposit flows and mortgage prepayments are greatly influenced by general interest rates, economic conditions and competition. We regularly review the need to adjust our investments in liquid assets based upon our assessment of: (1) expected loan demand, (2) expected deposit flows, (3) yields available on interest-earning deposits and securities, and (4) the objectives of our asset/liability management program. Excess liquid assets are invested generally in interest-earning deposits and short- and intermediate-term securities. Our most liquid assets are cash and cash equivalents. The levels of these assets are dependent on our operating, financing, lending and investing activities during any given period. At September 30, 2022, cash and cash equivalents totaled $50.8 million, a decrease from $118.5 million as of June 30, 2022. Unpledged securities classified as available for sale, which provide an additional source of liquidity, totaled $9.5 million at September 30, 2022, a decrease from $18.5 million as of June 30, 2022. We had the ability to borrow up to $223.0 million from the FHLB of New York, at September 30, 2022 of which $28.3 million was outstanding as of September 30, 2022. Additionally, as of September 30, 2022, we had an available line of credit with the FRB of New York’s discount window program of $102.8 million, and $25.0 million of fed funds lines of credit, neither of which had outstanding balances as of September 30, 2022. We have no material commitments or demands that are likely to affect our liquidity other than as set forth below. If loan demand was to increase faster than expected, or any unforeseen demand or commitment was to occur, we could access our borrowing sources detailed above. We had $14.4 million of loan commitments outstanding as of September 30, 2022 and $171.2 million of approved, but unadvanced, funds to borrowers. We also had $2.9 million in outstanding letters of credit at September 30, 2022. 36

Time deposits due within one year of September 30, 2022 totaled $203.0 million. If these deposits do not remain with us, we will be required to seek other sources of funds, including other time deposits and FHLB of New York advances. Depending on market conditions, we may be required to pay higher rates on such deposits or other borrowings than we currently pay on the time deposits at September 30, 2022. We believe, however, based on past experience that a significant portion of our time deposits will remain with us. We have the ability to attract and retain deposits by adjusting the interest rates offered. The Holding Company is a separate legal entity from the Bank and must provide for its own liquidity to pay any dividends to its shareholders, to repurchase shares of its common stock and for other corporate purposes. The Holding Company’s primary source of liquidity is dividend payments it may receive from the Bank.

PART II – OTHER INFORMATION Item 1. Legal Proceedings Periodically, there have been various claims and lawsuits against us, such as claims to enforce liens, condemnation proceedings on properties in which we hold security interests, claims involving the making and servicing of real property loans and other issues incident to our business. In addition, the Company has received demand letters from putative stockholders of the Company regarding the pending merger between the Company and Brookline Bancorp, Inc. In addition, on August 25, 2022, a complaint captioned Stephen Bushansky v. PCSB Financial Corporation et al. was filed in the United States District Court, Southern District of New York, naming as defendants the Company and the members of the Company’s board of directors (the “Complaint”). The complaint and the demand letters allege, among other things, that the proxy statement/prospectus contains materially incomplete and misleading information regarding the process that culminated in the merger agreement and the proposed transaction, the valuation analyses performed by the Company’s financial advisor, and potential conflicts of interest in connection with the proposed merger. The relief sought includes enjoining the consummation of the merger unless and until certain additional and allegedly material information is disclosed to the Company’s stockholders, rescinding and setting aside the merger to the extent already implemented, or granting rescissory damages, and awarding the plaintiff the cost of the action, including reasonable attorneys’ and experts’ fees. The Company believes that all allegations in the demand letters and complaint are without merit and intends to defend against them as appropriate. We do not believe that any pending legal proceedings would have a material adverse effect on our consolidated financial condition, results of operations or cash flows. 37
