The Company uses the accrual basis of accounting for financial statement purposes. The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The annualized results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results of operations that may be expected for the entire fiscal year. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All significant inter-company transactions and balances are eliminated in consolidation. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial position and the results of operations as of the dates and for the interim periods presented have been included. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes appearing in the Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”). A more detailed description of our accounting policies is included in the 2022 Annual Report, which remain significantly unchanged except for the Allowance for Credit Losses ("ACL") policy, resulting from the adoption of the Accounting Standard Update ("ASU") No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments and its amendments, (“ASU No. 2016-13”) as of January 1, 2023, as well as the addition of accounting policies related to treasury stock: Treasury stock - Treasury stock is carried at cost. Shares issued out of treasury are valued based on the weighted average cost. There have been no other significant changes to our accounting policies, or the estimates made pursuant to those policies as described in our 2022 Annual Report. Recently Adopted Accounting Standards ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments The Company adopted ASU No. 2016-13 inclusive of subsequent amendments as of January 1, 2023. ASU No. 2016-13 amends guidance on reporting credit losses for assets held on an amortized cost basis and available-for-sale debt securities, as well as off balance sheet credit exposures. For assets held at amortized cost, ASU No. 2016-13 eliminates the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. The amendments in ASU No. 2016-13 replace the incurred loss impairment methodology with a methodology that reflects the measurement of expected credit losses based on relevant information about past events, including historical loss experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of financial assets to present the net amount expected to be collected. For available for sale debt securities, credit losses will be presented as an allowance rather than as a write-down. For the Company, the amendments affected loans, debt securities, off-balance sheet credit exposures, and any other financial assets not excluded from the scope that have the contractual right to receive cash. The Company adopted ASU No. 2016-13 on a modified retrospective basis with a cumulative-effect adjustment to retained earnings as of the adoption date and, accordingly, the Company recorded a net of tax decrease of $17.8 million to retained earnings as of January 1, 2023. The results for prior period amounts continue to be reported in accordance with previously applicable GAAP. The below table illustrates the impact of the adoption of ASU 2016-13. January 1, 2023 Gross Adjustment Tax Impact Net Adjustment to Retained Earnings Assets: Allowance for credit losses on held-to-maturity securities $ 668 $ (184) $ 484 Allowance for credit losses on loans 21,229 (5,849) 15,380 Liabilities: Allowance for credit losses on off-balance sheet credit exposures 2,705 (744) 1,961 Total Day 1 Adjustment for Adoption of ASU 2016-13 $ 24,602 $ (6,777) $ 17,825 Allowance for Credit Losses - Available for Sale Securities: Any available for sale security in an unrealized loss position is assessed for Management's intent to sell, or if it is more likely than not that it will be required to sell before the recovery of its amortized cost basis. If either criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. Accrued interest receivable is excluded from the estimate of expected credit losses, as accrued interest receivable is reversed for securities placed on nonaccrual status. Securities issued by U.S. government entities are either explicitly or implicitly guaranteed by the U.S. government, and are highly rated by major ratings agencies and have a long history of no credit losses. For debt securities that do not meet the aforementioned criteria, the Company evaluates whether the decline in fair value has resulted from expected credit losses or other factors in making this assessment. Management considers the extent in which fair value is less than amortized cost, any changes to the rating of the security by a rating agency, and adverse conditions specifically related to the security, among other factors. If this assessment indicates that a credit loss exists, the present value of cash flows expected to be collected from the security are compared to the amortized cost basis of the security. If the present value of cash flows is expected to be collected is less than the amortized cost basis, a credit loss exists and an allowance for credit losses is recorded for the credit loss, limited by the amount that the fair value is less than the amortized cost basis. Any impairment that has not been recorded through an allowance for credit losses is recognized in other comprehensive income. There was no allowance for credit losses for available for sale securities as of January 1, 2023. Allowance for Credit Losses - Held-to-maturity Securities: Management measures expected credit losses on held-to-maturity securities on a collective basis by security type. The Company’s methodology to measure the allowance for credit losses incorporates both quantitative and qualitative information to assess lifetime expected credit losses. The calculation is based on projected annual default rates, loss severities, and prepayment rates. Expected credit losses are estimated over the contractual term of the securities, adjusted for forecasted prepayments when appropriate. Accrued interest receivable is excluded from the estimate of expected credit losses, as accrued interest receivable is reversed for securities placed on nonaccrual status. The Company has identified the following portfolio segments and measures the allowance for credit losses using the following methods: Mortgage-backed - Certain residential securities held by the Company are issued by U.S. government entities and agencies. These securities are either explicitly or implicitly guaranteed by the U.S. government, and are highly rated by major rating agencies and have a long history of no credit losses. Non-GSE residential and commercial mortgage-backed securities held by the Company are secured by pools of commercial or residential certificates. Asset-backed securities ("ABS") - ABS held by the Company are secured by pools of consumer products such as student loans, consumer loans, and consumer residential solar loans. Property assessed clean energy ("PACE assessments") - PACE assessments held by the Company are secured low loan to value long-term funding for energy efficient and renewable energy projects for residential or commercial projects. Other securities - Other securities held by the Company include corporate securities, municipal securities and small investments community reinvestment act investments secured by loans. Allowance for Credit Losses - Loans: The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of a financial asset or a group of financial assets so that the balance sheet reflects the net amount the Company expects to collect. Amortized cost is the principal balance outstanding, net of purchase premiums and discounts, and deferred fees and costs. Accrued interest receivable on loans is excluded from the estimate of expected credit losses, as accrued interest receivable is reversed for loans placed on nonaccrual status. Subsequent changes (favorable and unfavorable) in expected credit losses are recognized immediately in net income as a credit loss expense or a reversal of credit loss expense. Loans are charged off against the allowance when management believes the uncollectibility of a loan balance is confirmed. Expected recoveries do not exceed the aggregate of amounts previously charged-off and expected to be charged-off. Management calculates the estimation of the allowance for credit losses on loans on a quarterly basis. The Company’s methodology to measure the allowance for credit losses incorporates both quantitative and qualitative information to assess lifetime expected credit losses at the portfolio segment level. The quantitative component of the allowance model calculates future loan level balances by considering the loan segment baseline loss rate based on a peer group and severity rate. Expected credit losses are estimated over the contractual term of the loans, adjusted for forecasted prepayments when appropriate. The baseline loss rate is adjusted for relevant macroeconomic variables by loan segment that consider forecasted economic conditions. The adjusted loss rate is calculated for an eight quarter forecast period then reverts to the historical loss rate on a straight-line basis over four quarters. The loan level cash flows are discounted at the effective interest rate to calculate a loan level allowance which is aggregated at the loan segment level to arrive at the estimated allowance. Economic parameters are developed using available information relating to past events, current conditions, and reasonable and supportable forecasts. Historical credit experience provides the basis for the estimation of expected credit losses, with qualitative adjustments made to loan segments for differences in current loan-specific risk characteristics such as differences in underwriting standards, portfolio mix, delinquency levels and terms, as well as for changes in environmental conditions, such as changes in unemployment rates, property values or other relevant factors. The allowance for credit losses on loans is measured on a collective (pool) basis when similar risk characteristics exist. The Company has identified the following portfolio segments and measures the allowance for credit losses using the methods described above. Commercial and Industrial Loans - Loans in this classification are made to businesses and include term loans, lines of credit, and senior secured loans to corporations. Generally, these loans are secured by assets of the business and repayment is expected from the cash flows of the business. A weakened economy, and resultant decreased consumer and/or business spending, will have an effect on the credit quality in this loan class. Multifamily Mortgage Loans - Loans in this classification include income producing residential investment properties of five or more families. Loans are made to established owners with a proven and demonstrable record of strong performance. Repayment is derived generally from the rental income generated from the property and may be supplemented by the owners’ personal cash flow. Credit risk arises with an increase in vacancy rates, property mismanagement and the predominance of non-recourse loans that are customary in the industry. Commercial Real Estate Loans - Loans in this classification include income producing investment properties and owner-occupied real estate used for business purposes. The underlying properties are located largely in the Company’s primary market area. The cash flows of the income producing investment properties are adversely impacted by a downturn in the economy as evidenced by increased vacancy rates, which in turn, will have an effect on credit quality. In the case of owner-occupied real estate used for business purposes, a weakened economy and resultant decreased consumer and/or business spending will have an adverse effect on credit quality. Construction and Land Development Loans - Loans in this classification primarily include land loans to local individuals, contractors and developers for developing the land for sale or for the purpose of making improvements thereon. Repayment is derived primarily from sale of the lots/units including any pre-sold units. Credit risk is affected by market conditions, time to sell at an adequate price and cost overruns. To a lesser extent, this class includes commercial development projects that the Company finances, which in most cases are interest only during construction, and then convert to permanent financing. Construction delays, cost overruns, market conditions and the availability of permanent financing, to the extent such permanent financing is not being provided by the Bank, all affect the credit risk in this loan class. Residential Real Estate Loans - Loans in this classification are generally secured by owner-occupied residential real estate and repayment is dependent on the credit quality of the individual borrower. Loans in this class are secured by both first liens and second liens. The overall health of the economy, including unemployment rates and housing prices, can have an effect on the credit quality in this loan class. Consumer Solar Loans - Loans in this classification may be either secured or unsecured. This portfolio is comprised of residential solar loans. Repayment is dependent on the credit quality of the individual borrower and, if applicable, sale of the collateral securing the loan. Therefore, the overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this loan class. Consumer and Other Loans - Loans in this classification may be either secured or unsecured. This portfolio is comprised of student loans and other consumer products. Repayment is dependent on the credit quality of the individual borrower and, if applicable, sale of the collateral securing the loan. Therefore, the overall health of the economy, including unemployment rates and housing prices, will have an effect on the credit quality in this loan class. Loans that are determined to have unique risk characteristics are evaluated on an individual basis by Management. Loans evaluated individually are not included in the collective evaluation. Factors that may be considered are borrower delinquency trends and nonaccrual status, probability of foreclosure or note sale, changes in the borrower’s circumstances or cash collections, borrower’s industry, or other facts and circumstances of the loan or collateral. Individually Evaluated Loans with an ACL: For collateral-dependent loans where the Company has determined that foreclosure of the collateral is probable, or where the borrower is experiencing financial difficulty and the Company expects repayment of the loan to be provided substantially through the operation or sale of the collateral, the ACL is measured based on the difference between the fair value of the collateral, less the estimated costs to sell, and the amortized cost basis of the loan as of the measurement date. The fair value of real estate collateral is determined based on recent appraised values. The fair value of non-real estate collateral, may be determined based on an appraisal, net book value per the borrower’s financial statements, aging reports, or by reference to market activity, adjusted or discounted based on management’s historical knowledge, changes in market conditions from the time of the valuation and management’s expertise and knowledge of the borrower and its business. For non-collateral dependent loans, ACL is measured based on the difference between the present value of expected cash flows and the amortized cost basis of the loan as of the measurement date. Allowance for Credit Losses on Off-Balance Sheet Credit Exposures: The Company estimates expected credit losses over the contractual period in which the Company is exposed to credit risk via a contractual obligation to extend credit, unless that obligation is unconditionally cancellable by the Company for its security and loan portfolios. The allowance for credit losses on off-balance sheet credit exposures is recorded in other liabilities on the consolidated statements of financial condition, and adjusted through the credit loss expense which is recorded in the provision for credit losses on the consolidated statements of income. The estimate includes consideration of the likelihood that funding will occur and an estimate of expected credit losses on commitments expected to be funded over its estimated life, which is the same as the expected loss factor as determined based on the corresponding portfolio segment. At January 1, 2023, the Day 1 adjustment to allowance for credit losses on off-balance sheet credit exposures was $2.7 million, of which $2.6 million related to obligations on the loans portfolio, and $0.1 million related to obligations on the securities portfolio. ASU 2022-02, Financial Instruments - Credit Losses (Topic 326) - Troubled Debt Restructurings and Vintage Disclosures On March 31, 2022, the Financial Accounting Standards Board ("FASB") issued ASU 2022-02, which eliminates the troubled debt restructuring ("TDR") accounting model for creditors that have adopted Topic 326, “Financial Instruments – Credit Losses.” Specifically, rather than applying the recognition and measurement guidance for TDRs, this ASU requires entities to evaluate receivable modifications, consistent with the accounting for other loan modifications, to determine whether a modification made to a borrower results is a new loan or a continuation of the existing loan. In addition, under the new ASU, entities are no longer required to use a discounted cash flow ("DCF") method to measure the ACL as a result of a modification or restructuring with a borrower experiencing financial difficulty. If a DCF method is used, the post-modification-derived effective interest rate is to be used, instead of the original interest rate as stipulated under the current GAAP. This ASU also enhances the disclosure requirements related to certain modifications of receivables made to borrowers experiencing financial difficulty. This ASU amends the guidance on “vintage disclosures” to require the disclosure of current-period gross write-offs by year of origination. The Company adopted ASU 2022-02 on January 1, 2023 on a prospective basis. The adoption of the standard did not have a material impact on the financial statements.

During the three months ended March 31, 2023, a Corporate bond related to Silicon Valley Bank was placed on nonaccrual status following credit concerns over the issuer. As a result, Management charged-off the $1.2 million unrealized loss position given Management's intent to sell the Corporate bond and unlikely recovery of the unrealized position. The sale of the security in the second quarter of 2023 resulted in an immaterial additional loss. During the three months ended September 30, 2023, no available for sale securities were charged-off. As of September 30, 2023, none of the Company’s available for sale debt securities were in an unrealized loss position due to credit and therefore no allowance for credit losses on available for sale debt securities was required. The temporary impairment of fixed income securities is primarily attributable to changes in overall market interest rates and/or changes in credit/liquidity spreads since the investments were acquired. In general, as market interest rates rise and/or credit/liquidity spreads widen, the fair value of fixed rate securities will decrease, as market interest rates fall and/or credit spreads tighten, the fair value of fixed rate securities will increase. With respect to the Company’s security investments that are temporarily impaired as of September 30, 2023, management does not intend to sell these investments and does not believe it will be necessary to do so before anticipated recovery. If either criteria regarding intent or requirement to sell is met, the security's amortized cost basis is written down to fair value through income. The Company expects to collect all amounts due according to the contractual terms of these investments. Therefore, the Company does not hold an allowance for credit losses for available for sale securities at September 30, 2023. Held-to-maturity securities Management conducts an evaluation of expected credit losses on held-to-maturity securities on a collective basis by security type. Management monitors the credit quality of debt securities held-to-maturity through reasonable and supportable forecasts, reviews of credit trends on underlying assets, credit ratings, and other factors. Holdings of securities issued by GSEs with unrealized losses are either explicitly or implicitly guaranteed by the U.S. government, and are highly rated by major rating agencies and have a long history of no credit losses. With the exception of PACE assessments, which are generally not rated, our traditional securities were rated investment grade by at least one nationally recognized statistical rating organization with no ratings below investment grade. All issues were current as to their interest payments. We have had insignificant losses on PACE assessments that we have invested in and are not aware of any significant losses in the PACE bonds sector given the low loan-to-value position and the superior lien position on the property. Management considers that the temporary impairment of these investments as of September 30, 2023 is primarily due to an increase in interest rates and spreads since the time these investments were acquired. Accrued interest receivable on securities totaling $28.1 million and $23.2 million at September 30, 2023 and December 31, 2022, respectively, was included in other assets in the consolidated balance sheet and excluded from the amortized cost and estimated fair value totals in the table above.

One loan that was modified had a payment default during the three months ended September 30, 2023, and two loans had a payment default during the nine months ended September 30, 2023. In order to manage credit quality, we view the Company’s loan portfolio by various segments. For commercial loans, we assign individual credit ratings ranging from 1 (lowest risk) to 10 (highest risk) as an indicator of credit quality. These ratings are based on specific risk factors including (i) historical and projected financial results of the borrower, (ii) market conditions of the borrower’s industry that may affect the borrower’s future financial performance, (iii) business experience of the borrower’s management, (iv) nature of the underlying collateral, if any, including the ability of the collateral to generate sources of repayment, and (v) history of the borrower’s payment performance. These specific risk factors are then utilized as inputs in our credit model to determine the associated allowance for credit loss. Non-rated loans generally include residential mortgages and consumer loans. The below classifications follow regulatory guidelines and can be generally described as follows: • pass loans are of satisfactory quality; • special mention loans have a potential weakness or risk that may result in the deterioration of future repayment; • substandard loans are inadequately protected by the current net worth and paying capacity of the borrower or of the collateral pledged (these loans have a well-defined weakness, and there is a distinct possibility that the Company will sustain some loss); and • doubtful loans, based on existing circumstances, have weaknesses that make collection or liquidation in full highly questionable and improbable. In addition, residential loans are classified utilizing an inter-agency methodology that incorporates the extent of delinquency. Assigned risk rating grades are continuously updated as new information is obtained.

Assets are pledged to collateral capacity. As of September 30, 2023, the value of the other eligible assets had an estimated market value net of haircut totaling $1.88 billion (comprised of securities of $367.2 million and mortgage loans of $1.52 billion). The fair value of assets pledged to the FHLBNY is required to exceed outstanding advances. There were $4.4 million outstanding FHLBNY advances as of September 30, 2023 and $580.0 million in outstanding FHLBNY advances as of December 31, 2022. For the three months ended September 30, 2023, and 2022, interest expense on FHLBNY advances was $1.0 million and $24.8 thousand, respectively. For the nine months ended September 30, 2023, and 2022, interest expense on FHLBNY advances was $5.4 million and $24.8 thousand, respectively.

Of the 431,777 unvested RSUs and PSUs on September 30, 2023, the minimum units that will vest, solely due to a service test, are 305,814. The maximum units that will vest, assuming the highest payout on performance and market-based units, are 494,759. Compensation expense attributable to RSUs and PSUs was $1.1 million and $3.1 million for the three and nine months ended September 30, 2023, and $0.5 million and $1.5 million for the three and nine months ended September 30, 2022. Other expenses for directors were $0.1 million and $0.3 million for the three and nine months ended September 30, 2023, and $0.1 million and $0.4 million for the three and nine months ended September 30, 2022.

This expense may increase or decrease depending on the expected number of performance-based shares to be issued. This expense is expected to be recognized over 1.8 years. Employee Stock Purchase Plan On April 28, 2021, the Company's stockholders approved the Amalgamated Financial Corp. Employee Stock Purchase Plan (the "ESPP") which was implemented on March 2, 2022. The aggregate number of shares of common stock that may be purchased and issued under the ESPP will not exceed 500,000 of previously authorized shares. Under the terms of the ESPP, employees may authorize the withholding of up to 15% of their eligible compensation to purchase the Company's shares of common stock, not to exceed $25,000 of the fair market value of such common stock for any calendar year. The purchase price per shares acquired under the ESPP will never be less than 85% of the fair market value of the Company's common stock on the last day of the offering period. The Company's Board of Directors in its discretion may terminate the ESPP at any time with respect to any shares for which options have not been granted. The Compensation Committee of the Board of Directors (the "Committee") has the right to amend the ESPP without the approval of our stockholders; provided, that no such change may impair the rights of a participant with respect to any outstanding offering period without the consent of such participant, other than a change determined by the Committee to be necessary to comply with applicable law. A participant may not dispose of shares acquired under the ESPP until six months following the grant date of such shares, or any earlier date as of which the Committee has determined that the participant would qualify for a hardship distribution from the Company’s 401(k) Plan. Accordingly, the fair value award associated with their discounted purchase price is expensed at the time of purchase. The below following summarizes the shares purchased under the ESPP since the inception of the plan: Number of Shares Shares available for purchase at December 31, 2022 478,081 Purchases during the three months ended: March 31, 2023 (21,919) June 30, 2023 (7,835) September 30, 2023 (7,918) Year-to-date purchases (37,672) Remaining shares available for purchase at September 30, 2023 440,409 The expense related to the discount on purchased shares for the three months ended September 30, 2023 and September 30, 2022 was $20.4 thousand and $25.2 thousand, respectively, and is recorded within compensation and employee benefits expense on the Consolidated Statements of Income. The expense for the nine months ended September 30, 2023 and September 30, 2022 was $97.4 thousand and $77.3 thousand, respectively.

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	9 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE OF FINANCIAL INSTRUMENTS	FAIR VALUE OF FINANCIAL INSTRUMENTS Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assumptions are developed based on prioritizing information within a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. A description of the disclosure hierarchy and the types of financial instruments recorded at fair value that management believes would generally qualify for each category are as follows: Level 1 - Valuations are based on quoted prices in active markets for identical assets or liabilities. Accordingly, valuation of these assets and liabilities does not entail a significant degree of judgment. Examples include most U.S. Government securities and exchange-traded equity securities. Level 2 - Valuations are based on either quoted prices in markets that are not considered to be active or significant inputs to the methodology that are observable, either directly or indirectly. Financial instruments in this level would generally include mortgage-related securities and other debt issued by GSEs, non-GSE mortgage-related securities, corporate debt, certain redeemable fund investments and certain trust preferred securities. Level 3 - Valuations are based on inputs to the methodology that are unobservable and significant to the fair value measurement. These inputs reflect management’s own judgments about the assumptions that market participants would use in pricing the assets and liabilities. Assets Measured at Fair Value on a Recurring Basis Available for sale securities The Company’s available for sale securities are reported at fair value. Investments in fixed income securities are generally valued based on evaluations provided by an independent pricing service. These evaluations represent an exit price or their opinion as to what a buyer would pay for a security, typically in an institutional round lot position, in a current sale. The pricing service utilizes evaluated pricing techniques that vary by asset class and incorporate available market information and, because many fixed income securities do not trade on a daily basis, applies available information through processes such as benchmark curves, benchmarking of available securities, sector groupings and matrix pricing. Model processes, such as option adjusted spread models, are used to value securities that have prepayment features. In those limited cases where pricing service evaluations are not available for a fixed income security, management will typically value those instruments using observable market inputs in a discounted cash flow analysis. The following summarizes those financial instruments measured at fair value on a recurring basis in the Consolidated Statements of Financial Condition as of the dates indicated, categorized by the relevant class of investment and level of the fair value hierarchy: September 30, 2023 (In thousands) Level 1 Level 2 Level 3 Total Available for sale securities: Mortgage-related: GSE residential CMOs $ — $ 353,171 $ — $ 353,171 GSE commercial certificates & CMO — 128,241 — 128,241 Non-GSE residential certificates — 96,751 — 96,751 Non-GSE commercial certificates — 84,877 — 84,877 Other debt: U.S. Treasury 197 — — 197 ABS — 667,402 — 667,402 Trust preferred — 9,319 — 9,319 Corporate — 112,966 — 112,966 Residential PACE assessments — — 38,526 38,526 Total assets carried at fair value $ 197 $ 1,452,727 $ 38,526 $ 1,491,450 December 31, 2022 (In thousands) Level 1 Level 2 Level 3 Total Available for sale securities: Mortgage-related: GSE residential CMOs $ — $ 389,260 $ — $ 389,260 GSE commercial certificates & CMO — 213,786 — 213,786 Non-GSE residential certificates — 107,080 — 107,080 Non-GSE commercial certificates — 97,482 — 97,482 Other debt: U.S. Treasury 192 — — 192 ABS — 862,163 — 862,163 Trust preferred — 10,143 — 10,143 Corporate — 132,370 — 132,370 Total assets carried at fair value $ 192 $ 1,812,284 $ — $ 1,812,476 Assets Measured at Fair Value on a Non-recurring Basis Certain financial assets and financial liabilities are measured at fair value on a non-recurring basis. That is, they are subject to fair value adjustments in certain circumstances. Financial assets measured at fair value on a non-recurring basis include certain individually evaluated loans (or impaired loans prior to the adoption of ASU 2016-13) reported at the fair value of the underlying collateral if repayment is expected solely from the collateral. The following tables summarize assets measured at fair value on a non-recurring basis in the Consolidated Statements of Financial Condition as of the dates indicated, categorized by the relevant class of investment and level of the fair value hierarchy: September 30, 2023 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Fair Value Measurements: Individually analyzed loans $ 3,569 $ — $ — $ 3,569 $ 3,569 December 31, 2022 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Fair Value Measurements: Impaired loans $ 3,315 $ — $ — $ 3,315 $ 3,315 Financial Instruments Not Measured at Fair Value For those financial instruments that are not recorded at fair value in the consolidated statements of financial condition, but are measured at fair value for disclosure purposes, management follows the same fair value measurement principles and guidance as for instruments recorded at fair value. For a description of the methods, factors and significant assumptions utilized in estimating the fair values for significant categories of financial instruments not measured at fair value, refer to footnote 14, Fair Value of Financial Instruments , included in the Annual Report on Form 10-K for the year ended December 31, 2022. An additional category of financial instrument not measured at fair value that was not previously included in the Annual Report on Form 10-K is summarized below: • Other borrowings - Other borrowings are valued using a present value technique that incorporates current rates offered on borrowings of comparable remaining maturity. Other borrowings are categorized as Level 2. There are significant limitations in estimating the fair value of financial instruments for which an active market does not exist. Due to the degree of management judgment that is often required, such estimates tend to be subjective, sensitive to changes in assumptions and imprecise. Such estimates are made as of a point in time and are impacted by then-current observable market conditions; also such estimates do not give consideration to transaction costs or tax effects if estimated unrealized gains or losses were to become realized in the future. Because of inherent uncertainties of valuation, the estimated fair value may differ significantly from the value that would have been used had a ready market for the investment existed and the difference could be material. Lastly, consideration is not given to nonfinancial instruments, including various intangible assets, which could represent substantial value. Fair value estimates are not necessarily representative of the Company’s total enterprise value. The following table summarizes the financial statement basis and estimated fair values for significant categories of financial instruments: September 30, 2023 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Financial assets: Cash and cash equivalents $ 140,219 $ 140,219 $ — $ — $ 140,219 Held-to-maturity securities 1,681,860 — 547,072 930,734 1,477,806 Loans held for sale 2,189 — — 2,189 2,189 Loans receivable, net 4,296,930 — — 3,868,176 3,868,176 Accrued interest receivable 47,745 276 12,675 34,794 47,745 Financial liabilities: Deposits payable on demand $ 6,418,406 $ — $ 6,418,406 $ — $ 6,418,406 Time deposits and brokered CDs 572,448 — 567,275 — 567,275 FHLBNY advances 4,381 — 4,381 — 4,381 Other borrowings 230,000 — 228,658 — 228,658 Subordinated debt, net 70,427 — 57,045 — 57,045 Accrued interest payable 10,215 — 10,215 — 10,215 December 31, 2022 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Financial assets: Cash and cash equivalents $ 63,540 $ 63,540 $ — $ — $ 63,540 Held-to-maturity securities 1,541,301 — 574,609 840,262 1,414,871 Loans held for sale 7,943 — 7,943 7,943 Loans receivable, net 4,060,971 — — 3,718,308 3,718,308 Resell agreements 25,754 — — 25,754 25,754 Accrued interest and dividends receivable 41,441 17 12,197 29,227 41,441 Financial liabilities: Deposits payable on demand $ 6,369,087 $ — $ 6,369,087 $ — $ 6,369,087 Time deposits and brokered CDs 225,950 — 225,805 — 225,805 FHLBNY advances 580,000 — 580,000 — 580,000 Subordinated debt, net 77,708 — 68,966 — 68,966 Accrued interest payable 1,218 — 1,218 — 1,218

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS, CONTINGENCIES AND OFF BALANCE SHEET RISK	COMMITMENTS, CONTINGENCIES AND OFF BALANCE SHEET RISK Credit Commitments The Company is party to various credit related financial instruments with off balance sheet risk. The Company, in the normal course of business, issues such financial instruments in order to meet the financing needs of its customers. These financial instruments include commitments to extend credit and standby letters of credit. Such commitments involve, to varying degrees, elements of credit and interest rate risk in excess of the amounts recognized in the consolidated statements of financial condition. The following financial instruments were outstanding whose contract amounts represent credit risk as of the related periods: September 30, 2023 December 31, 2022 (In thousands) Commitments to extend credit $ 532,259 $ 723,902 Standby letters of credit 30,601 29,568 Total $ 562,860 $ 753,470 Commitments to extend credit are contracts to lend to a customer as long as there is no violation of any condition established in the contract. These commitments have fixed expiration dates and other termination clauses and generally require the payment of nonrefundable fees. Since a portion of the commitments are expected to expire without being drawn upon, the contractual principal amounts do not necessarily represent future cash requirements. The Company’s maximum exposure to credit risk is represented by the contractual amount of these instruments. These instruments represent ultimate exposure to credit risk only to the extent they are subsequently drawn upon by customers. Standby letters of credit are conditional lending commitments issued by the Company to guarantee the financial performance of a customer to a third party. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loan facilities to customers. The balance sheet carrying value of standby letters of credit approximates any nonrefundable fees received but not yet recorded as income. The Company considers this carrying value, which is not material, to approximate the estimated fair value of these financial instruments. The Company reserves for the credit risk inherent in off balance sheet credit commitments. Upon adoption of ASU 2016-13 on January 1, 2023, the Day 1 adjustment to allowance for credit losses on off-balance sheet credit exposures was $2.7 million. This allowance, which is included in other liabilities, amounted to approximately $3.8 million as of September 30, 2023, compared to a reserve of $1.6 million as of December 31, 2022. The provision for credit losses related to off balance sheet credit commitments was a recovery of $1.3 million and $0.4 million for the three and nine months ended September 30, 2023, and the expense related to off balance sheet credit commitments in other non-interest expense was a recovery of $0.2 million and an expense of $0.2 million for the three and nine months ended September 30, 2022. Investment Obligations The Company is a party to agreements with Pace Funding Group LLC, which operates Home Run Financing, for the purchase of PACE assessment securities until December 2023. As of September 30, 2023, the Company had purchased $662.4 million of these obligations and had an estimated remaining commitment of $69.3 million. The PACE assessments have equal-lien priority with property taxes and generally rank senior to first lien mortgages. These investments are currently held in the Company's held-to-maturity investment portfolio. The Company evaluates these obligations for credit risk and the recorded reserve is immaterial. Other Commitments and Contingencies In the ordinary course of business, there are various legal proceedings pending against the Company. Based on the opinion of counsel, management believes that the aggregate liabilities, if any, arising from such actions would not have a material adverse effect on the consolidated financial position or results of operations of the Company. As part of the Company's ongoing investments in variable interest entity ("VIE") projects, we also have commitments to provide financing, which are included in Note 14.

Leases [Abstract]
LEASES	LEASES The Bank as a lessee has operating leases primarily consisting of real estate arrangements where the Company operates its headquarters, branches and business production offices. All leases identified as in scope are accounted for as operating leases as of September 30, 2023. These leases are typically long-term leases and generally are not complicated arrangements or structures. Several of the leases contain renewal options at a rate comparable to the fair market value based on comparable analysis to similar properties in the Bank’s geographies. Real estate operating leases are presented as a right-of-use (“ROU”) asset and a related operating lease liability on the Consolidated Statements of Financial Condition. The ROU asset represents the Company’s right to use the underlying asset for the lease term and the operating lease liabilities represent the obligation to make lease payments arising from the lease. The Company applied its incremental borrowing rate (“IBR”) as the discount rate to the remaining lease payments to derive a present value calculation for initial measurement of the operating lease liability. The IBR reflects the interest rate the Company would have to pay to borrow on a collateralized basis over a similar term for an amount equal to the lease payments. Lease expense is recognized on a straight-line basis over the lease term. The following table summarizes our lease cost and other operating lease information: Three Months Ended Nine Months Ended 2023 2022 2023 2022 (In thousands) Operating lease cost $ 1,814 $ 2,257 $ 5,386 $ 6,765 Cash paid for amounts included in the measurement of operating leases liability $ 2,823 $ 2,714 $ 8,452 $ 7,976 Note: Sublease income and variable income or expense considered immaterial The weighted average remaining lease term on operating leases at September 30, 2023 and September 30, 2022 was 3.2 years and 4.2 years, respectively. The weighted average discount rate used for the operating lease liability was 3.26% and 3.25% at September 30, 2023 and September 30, 2022, respectively. The following table presents the remaining commitments for operating lease payments for the next five years and thereafter, as well as a reconciliation to the discounted operating leases liability recorded in the Consolidated Statements of Financial Condition as of September 30, 2023: (In thousands) As of September 30, 2023 2023 $ 2,842 2024 11,324 2025 10,593 2026 9,200 2027 959 Thereafter — Total undiscounted operating lease payments 34,918 Less: present value adjustment 1,676 Total Operating leases liability $ 33,242

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND INTANGIBLE ASSETS	GOODWILL AND INTANGIBLE ASSETS Goodwill In accordance with GAAP, the Company performs an annual test as of June 30 to identify potential impairment of goodwill, or more frequently if events or circumstances indicate a potential impairment may exist. If the carrying amount of the Company, as a sole reporting unit, including goodwill, exceeds its fair value, an impairment loss is recognized in an amount equal to that excess up to the amount of the recorded goodwill. The Company performed its annual test based upon market data as of June 30, 2023 and estimates and assumptions that the Company believes most appropriate for the analysis. Based on the qualitative analysis performed in accordance with ASC 350, the Company determined it is more likely than not that goodwill was not impaired as of June 30, 2023. During the three and nine months ended September 30, 2023, there were no events or circumstances that would indicate that a potential impairment exists. Changes in certain assumptions used in the Company's assessment could result in significant differences in the results of the impairment test. Should market conditions or management’s assumptions change significantly in the future, an impairment to goodwill is possible. At September 30, 2023 and December 31, 2022, the carrying amount of goodwill was $12.9 million. Intangible Assets The following table reflects the estimated amortization expense, comprised entirely by the Company’s core deposit intangible asset, for the next five years and thereafter: (In thousands) Total 2023 $ 222 2024 730 2025 574 2026 419 2027 265 Thereafter 229 Total $ 2,439 Accumulated amortization of the core deposit intangible was $6.6 million as of September 30, 2023. Amortization expense recognized on the core deposit intangible was $0.2 million and $0.3 million for the three months ended September 30, 2023 and September 30, 2022, respectively, and $0.7 million and $0.8 million for the nine months ended September 30, 2023 and September 30, 2022, respectively.

An unrelated third party is the managing member and has control over the significant activities of the variable interest entities. The Company generates a return through the receipt of tax credits allocated to the projects, as well as operational distributions. The primary risk of loss is generally mitigated by policies requiring that the project qualify for the expected tax credits prior to the Company making its investment. Any loans to the VIE are secured. As of September 30, 2023, the Company's maximum exposure to loss is $67.0 million.

Accounting Policies [Abstract]
Basis of Accounting	The accounting and reporting policies of the Company conform to accounting principles generally accepted in the United States of America, or GAAP and predominant practices within the banking industry. The Company uses the accrual basis of accounting for financial statement purposes.
Consolidation	The accompanying unaudited consolidated financial statements have been prepared in accordance with U.S. generally accepted accounting principles (“GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. The annualized results of operations for the three and nine months ended September 30, 2023 are not necessarily indicative of the results of operations that may be expected for the entire fiscal year. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). All significant inter-company transactions and balances are eliminated in consolidation. In the opinion of management, all adjustments necessary for a fair presentation of the consolidated financial position and the results of operations as of the dates and for the interim periods presented have been included. These unaudited consolidated financial statements should be read in conjunction with the audited consolidated financial statements and related notes appearing in the Annual Report on Form 10-K for the year ended December 31, 2022 (the “2022 Annual Report”).
Treasury stock	Treasury stock - Treasury stock is carried at cost. Shares issued out of treasury are valued based on the weighted average cost.
Recently Adopted Accounting Standards	Recently Adopted Accounting Standards ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326) - Measurement of Credit Losses on Financial Instruments The Company adopted ASU No. 2016-13 inclusive of subsequent amendments as of January 1, 2023. ASU No. 2016-13 amends guidance on reporting credit losses for assets held on an amortized cost basis and available-for-sale debt securities, as well as off balance sheet credit exposures. For assets held at amortized cost, ASU No. 2016-13 eliminates the probable initial recognition threshold in current GAAP and, instead, requires an entity to reflect its current estimate of all expected credit losses. The amendments in ASU No. 2016-13 replace the incurred loss impairment methodology with a methodology that reflects the measurement of expected credit losses based on relevant information about past events, including historical loss experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The allowance for credit losses is a valuation account that is deducted from the amortized cost basis of financial assets to present the net amount expected to be collected. For available for sale debt securities, credit losses will be presented as an allowance rather than as a write-down. For the Company, the amendments affected loans, debt securities, off-balance sheet credit exposures, and any other financial assets not excluded from the scope that have the contractual right to receive cash.
Reclassifications	ReclassificationsCertain reclassifications have been made to prior year amounts to conform to the current year presentation, however such reclassifications did not change stockholders' equity or net income.
Fair Value of Financial Instruments	Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Assumptions are developed based on prioritizing information within a fair value hierarchy that gives the highest priority to quoted prices in active markets and the lowest priority to unobservable data. A description of the disclosure hierarchy and the types of financial instruments recorded at fair value that management believes would generally qualify for each category are as follows: Level 1 - Valuations are based on quoted prices in active markets for identical assets or liabilities. Accordingly, valuation of these assets and liabilities does not entail a significant degree of judgment. Examples include most U.S. Government securities and exchange-traded equity securities. Level 2 - Valuations are based on either quoted prices in markets that are not considered to be active or significant inputs to the methodology that are observable, either directly or indirectly. Financial instruments in this level would generally include mortgage-related securities and other debt issued by GSEs, non-GSE mortgage-related securities, corporate debt, certain redeemable fund investments and certain trust preferred securities.
