BASIS OF PRESENTATION AND CONSOLIDATION	BASIS OF PRESENTATION AND CONSOLIDATION Basis of Accounting and Changes in Significant Accounting Policies In this discussion, unless the context indicates otherwise, references to “we,” “us,” “our” and the “Company” refer to Amalgamated Financial Corp. and Amalgamated Bank. References to the “Bank” refer to Amalgamated Bank. 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. 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 months ended March 31, 2024 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 (the “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, 2023 (the “2023 Annual Report”). A more detailed description of our accounting policies is included in the 2023 Annual Report, which remain significantly unchanged. There have been no other significant changes to our accounting policies, or the estimates made pursuant to those policies as described in our 2023 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 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.

The Company controls and monitors inherent credit risk in its securities portfolio through due diligence, diversification, concentration limits, periodic securities reviews, and by investing in low risk securities. This includes high quality Non-Agency Securities, low loan-to-value ("LTV") PACE assessments and a significant portion of the securities portfolio in GSE obligations. GSEs include the Federal Home Loan Mortgage Corporation (“FHLMC”), the Federal National Mortgage Association (“FNMA”), the Government National Mortgage Association (“GNMA”) and the Small Business Administration (“SBA”). GNMA is a wholly owned U.S. Government corporation whereas FHLMC and FNMA are private. Mortgage-related securities may include mortgage pass-through certificates, participation certificates and CMOs. At March 31, 2024 and March 31, 2023, there were no holdings of securities of any one issuer, other than the U.S. Government and its agencies, in an amount greater than 10% of stockholders' equity. The following summarizes the fair value and unrealized losses for available for sale securities as of March 31, 2024 and December 31, 2023, respectively, segregated between securities that have been in an unrealized loss position for less than twelve months and those that have been in a continuous unrealized loss position for twelve months or longer at the respective dates: March 31, 2024 Less Than Twelve Months Twelve Months or Longer Total (In thousands) Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized Available for sale: Traditional securities: GSE certificates & CMOs $ 13,115 $ 52 $ 394,753 $ 37,980 $ 407,868 $ 38,032 Non-GSE certificates & CMOs — — 186,453 19,908 186,453 19,908 ABS 49,551 33 411,349 17,738 460,900 17,771 Corporate — — 121,373 18,653 121,373 18,653 Other 198 1 3,691 307 3,889 308 Total available for sale $ 62,864 $ 86 $ 1,117,619 $ 94,586 $ 1,180,483 $ 94,672 December 31, 2023 Less Than Twelve Months Twelve Months or Longer Total (In thousands) Fair Value Unrealized Fair Value Unrealized Fair Value Unrealized Available for sale: Traditional securities: GSE certificates & CMOs $ — $ — $ 460,239 $ 40,545 $ 460,239 $ 40,545 Non-GSE certificates & CMOs — — 196,860 21,690 196,860 21,690 ABS 53,133 122 526,868 20,868 580,001 20,990 Corporate — — 120,741 19,297 120,741 19,297 Other — — 3,888 309 3,888 309 Total available for sale $ 53,133 $ 122 $ 1,308,596 $ 102,709 $ 1,361,729 $ 102,831 Available for sale securities As discussed in Note 1, upon adoption of the Current Expected Credit Losses ("CECL") standard, no allowance for credit losses was recorded on available for sale securities. During the three months ended March 31, 2023, the Company charged-off an unrealized loss position of $1.2 million related to a corporate bond related to Silicon Valley Bank following credit concerns over the issuer, and the sale of the security resulted in an immaterial additional loss. As of March 31, 2024, 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 March 31, 2024, 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 March 31, 2024. 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, these 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. There have been no significant losses on PACE assessments that we have invested in 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 March 31, 2024 is primarily due to an increase in interest rates and spreads since the time these investments were acquired.

Commercial real estate Modification added a weighted average 0.5 years to the life of the modified loan. Construction and land development Modifications added a weighted average 0.8 years to the life of the modified loans. In the prior twelve months, ten loan modifications were made to borrowers experiencing financial difficulty. One loan that was modified during this period had a payment default during the three months ended March 31, 2024. 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.

Advance from Federal Home Loan Bank [Abstract]
BORROWED FUNDS	BORROWED FUNDS FHLBNY advances are collateralized by the FHLBNY stock owned by the Bank plus a pledge of other eligible assets comprised of securities and mortgage loans. Assets are pledged to collateral capacity. As of March 31, 2024, the value of the other eligible assets had an estimated market value net of haircut totaling $2.07 billion (comprised of securities of $395.1 million and mortgage loans of $1.67 billion). The fair value of assets pledged to the FHLBNY is required to exceed outstanding advances. There were $9.1 million outstanding FHLB advances as of March 31, 2024 and $4.4 million in outstanding FHLBNY advances as of December 31, 2023. For the three months ended March 31, 2024, and 2023, interest expense on FHLBNY advances was zero and $3.0 million, respectively. In addition to FHLBNY advances, the Company uses other borrowings for short-term borrowing needs. Federal funds lines of credit are extended to the Company by nonaffiliated banks with which a correspondent banking relationship exists. At March 31, 2024, and December 31, 2023 there was no outstanding balance related to federal funds purchased. In addition, following the bank failures in 2023, the Federal Reserve created a new Bank Term Funding Program ("BTFP") as an additional source of liquidity against high-quality securities, offering loans of up to one year to eligible institutions pledging qualifying assets as collateral. At March 31, 2024, there was an outstanding balance of $60.0 million related to the BTFP due in 2024 with a weighted average rate of 4.71%, and an outstanding balance of $230.0 million due in 2024 with a weighted average rate of 4.50% at December 31, 2023. For the three months ended March 31, 2024, and 2023, interest expense on other borrowings was $2.4 million and $0.2 million, respectively.

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 1.4 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, 2023 424,848 Purchases during the three months ended: March 31, 2024 (10,175) Remaining shares available for purchase at March 31, 2024 414,673 The expense related to the discount on purchased shares for the three months ended March 31, 2024 and March 31, 2023 was $37 thousand and $58 thousand, respectively, and is recorded within compensation and employee benefits expense on the Consolidated Statements of Income.

FAIR VALUE OF FINANCIAL INSTRUM

FAIR VALUE OF FINANCIAL INSTRUMENTS	3 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: March 31, 2024 (In thousands) Level 1 Level 2 Level 3 Total Available for sale securities: Traditional securities: GSE certificates & CMOs $ — $ 465,788 $ — $ 465,788 Non-GSE certificates & CMOs — 186,453 — 186,453 ABS — 668,290 — 668,290 Corporate — 121,373 — 121,373 Other 198 3,691 — 3,889 PACE assessments: Residential PACE assessments — — 82,258 82,258 Total assets carried at fair value $ 198 $ 1,445,595 $ 82,258 $ 1,528,051 December 31, 2023 (In thousands) Level 1 Level 2 Level 3 Total Available for sale securities: Traditional securities: GSE certificates & CMOs $ — $ 480,615 $ — $ 480,615 Non-GSE certificates & CMOs — 196,860 — 196,860 ABS — 627,635 — 627,635 Corporate — 120,741 — 120,741 Other 199 3,689 — 3,888 PACE assessments: Residential PACE assessments — — 53,303 53,303 Total assets carried at fair value $ 199 $ 1,429,540 $ 53,303 $ 1,483,042 The table below presents a reconciliation of all assets measured at fair value on a recurring basis using significant unobservable inputs (Level 3) for the three months ended March 31, 2024 and March 31, 2023 : Residential PACE Assessments March 31, 2024 March 31, 2023 (In thousands) Balance of recurring Level 3 assets at January 1 $ 53,303 $ — Amortization included in interest income 261 — Change in unrealized holding gains/losses included in other comprehensive income 536 — Purchases 34,879 — Sales (6,284) — Principal paydowns (437) — Balance of recurring Level 3 assets at March 31 $ 82,258 $ — The fair value of the Company's PACE assessments are determined internally by calculating discounted cash flows using expected conditional prepayment rates, market spreads, and the Treasury yield curve. Qualitative assessments from recent commentary from dealers or investors or issuers, information revealed from secondary market trades of clean energy senior asset-backed securities, and volatility in the marketplace are reviewed and incorporated into the calculations.

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: March 31, 2024 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Fair Value Measurements: Individually analyzed loans $ 1,498 $ — $ — $ 1,498 $ 1,498 $ 1,498 $ — $ — $ 1,498 $ 1,498 At December 31, 2023, there were no individually analyzed collateral-dependent loans. 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, 2023. 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: March 31, 2024 (In thousands) Carrying Value Level 1 Level 2 Level 3 Estimated Fair Value Financial assets: Cash and cash equivalents $ 155,204 $ 155,204 $ — $ — $ 155,204 Held-to-maturity securities 1,673,962 — 571,999 949,622 1,521,621 Loans held for sale 2,137 — — 2,137 2,137 Loans receivable, net 4,359,380 — — 4,026,693 4,026,693 Resell agreements 131,242 — — 131,242 131,242 Accrued interest receivable 53,436 281 13,111 40,044 53,436 Financial liabilities: Deposits payable on demand $ 6,946,272 $ — $ 6,946,272 $ — $ 6,946,272 Time deposits and brokered CDs 359,493 — 357,684 — 357,684 FHLBNY advances 9,135 — 8,818 — 8,818 Other borrowings 60,000 — 59,958 — 59,958 Subordinated debt, net 70,570 — 56,456 — 56,456 Accrued interest payable 6,640 — 6,640 — 6,640 December 31, 2023 (In thousands) Carrying Level 1 Level 2 Level 3 Estimated Financial assets: Cash and cash equivalents $ 90,570 $ 90,570 $ — $ — $ 90,570 Held-to-maturity securities 1,696,834 — 575,418 974,091 1,549,509 Loans held for sale 1,817 — 1,817 1,817 Loans receivable, net 4,345,628 — — 4,029,142 4,029,142 Resell agreements 50,000 — — 50,000 50,000 Accrued interest receivable 55,484 43 12,645 42,796 55,484 Financial liabilities: Deposits payable on demand $ 6,582,321 $ — $ 6,582,321 $ — $ 6,582,321 Time deposits and brokered CDs 429,667 — 428,116 — 428,116 FHLBNY advances 4,381 — 4,381 — 4,381 Other borrowings 230,000 — 229,711 — 229,711 Subordinated debt, net 70,546 — 56,790 — 56,790 Accrued interest payable 12,270 — 12,270 — 12,270

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: March 31, 2024 December 31, 2023 (In thousands) Commitments to extend credit $ 511,509 $ 514,206 Standby letters of credit 31,213 31,678 Total $ 542,722 $ 545,884 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. This allowance, which is included in other liabilities, amounted to approximately $4.9 million as of March 31, 2024, compared to an allowance of $4.2 million as of December 31, 2023. The provision for credit losses related to off balance sheet credit commitments was $0.7 million for the three months ended March 31, 2024, and $0.1 million for the three months ended March 31, 2023. 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 January 2025. As of March 31, 2024, the Company had purchased $753.7 million of these obligations and had an estimated remaining commitment of $119.7 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 VIE projects, we also have commitments to provide financing, which are included in footnote 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 March 31, 2024. 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 Three Months Ended (In thousands) Operating lease cost $ 1,840 $ 1,777 Cash paid for amounts included in the measurement of operating leases liability $ 4,186 $ 2,813 Note: Sublease income and variable income or expense considered immaterial The weighted average remaining lease term on operating leases at March 31, 2024 and March 31, 2023 was 2.9 years and 3.6 years, respectively. The weighted average discount rate used for the operating lease liability was 3.15% and 3.24% at March 31, 2024 and March 31, 2023, 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 March 31, 2024: (In thousands) As of March 31, 2024 2024 $ 8,076 2025 10,797 2026 8,881 2027 747 2028 — Thereafter — Total undiscounted operating lease payments 28,501 Less: present value adjustment 1,251 Total Operating leases liability $ 27,250

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 more likely than not that goodwill was not impaired as of June 30, 2023. During the three months ended March 31, 2024, 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 March 31, 2024 and December 31, 2023, 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 2024 $ 547 2025 574 2026 419 2027 265 2028 111 Thereafter 118 Total $ 2,034 Accumulated amortization of the core deposit intangible was $7.0 million as of March 31, 2024. Amortization expense recognized on the core deposit intangible was $0.2 million and $0.2 million for the three months ended March 31, 2024 and March 31, 2023, respectively.

VARIABLE INTEREST ENTITIES	VARIABLE INTEREST ENTITIES Tax Credit Investments The Company makes investments in unconsolidated entities that construct, own and operate solar generation facilities. An unrelated third party is the managing member and has control over the significant activities of the variable interest entities ("VIE"). 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 March 31, 2024, the Company's maximum exposure to loss is $63.0 million.

Accounting Policies [Abstract]
Basis of Accounting and Changes in Significant Accounting Policies	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 months ended March 31, 2024 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 (the “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, 2023 (the “2023 Annual Report”). A more detailed description of our accounting policies is included in the 2023 Annual Report, which remain significantly unchanged.

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.
