Priscilla Sims Brown, President and Chief Executive Officer, commented, “We are achieving our results because our banking model is flexible. We have many levers we can pull to drive performance and that creates reliability and predictability for our shareholders, customers, and employees.” Second Quarter Earnings Net income was $26.0 million, or $0.84 per diluted share, compared to $25.0 million, or $0.81 per diluted share, for the prior quarter. The $1.0 million increase during the quarter was primarily driven by a scheduled $2.6 million increase in non- core income related to solar tax equity investments, a $2.3 million increase in net interest income, and a $1.1 million decrease in non-interest expense. This was partially offset by a $4.3 million increase in provision for credit losses, the effect from a $0.8 million net valuation gain on residential loans sold during the previous quarter, and a $0.4 million increase in losses on sales of securities and other assets compared to the linked quarter. Core net income1 was $27.0 million, or $0.88 per diluted share, compared to $27.1 million, or $0.88 per diluted share for the prior quarter. Excluded from core net income for the quarter, pre-tax, was $1.0 million of losses on the sale of securities and other assets, $0.3 million of scheduled accelerated depreciation from solar tax equity investments, $0.1 million of severance costs, and $0.1 million of ICS One-Way Sell fee income. Excluded from core net income for the first quarter of 2025, pre-tax, was $2.9 million of accelerated depreciation from solar tax equity investments, a $0.8 million net valuation gain from residential loans sold during the quarter, and $0.7 million of losses on the sale of securities. Net interest income was $72.9 million, compared to $70.6 million for the prior quarter. Loan interest income increased $0.9 million and loan yields increased 5 basis points despite a $35.6 million decrease in average loan balances, primarily due to completion of a residential loan pool sale in the prior quarter. In addition, commercial loan originations were offset by paydowns and payoffs on lower-yielding commercial and residential loans. Interest income on securities increased $2.0 million driven by an increase in the average balance of securities of $141.2 million despite a slight decline in securities yields of 4 basis points. Interest expense on total interest-bearing deposits increased $1.7 million driven primarily by an increase in the average balance of total interest-bearing deposits of $201.0 million, while interest-bearing deposits cost remained flat. Net interest margin was 3.55%, the same as the prior quarter largely due to a higher average balance of interest-bearing deposits as noted above, which resulted in a slightly higher blended cost of funds. This offset the interest income generated by the higher average balance of securities and modestly higher loan yields. Additionally, income from prepayment penalties had a one basis point impact on net interest margin in the current quarter, compared to no impact in the prior quarter. Provision for credit losses was an expense of $4.9 million, compared to an expense of $0.6 million in the prior quarter. The increase in the second quarter was primarily driven by a $2.3 million increase in reserve for one syndicated commercial and industrial loan as well as the macroeconomic forecasts used in the CECL model, primarily related to the consumer solar loan portfolio, which can be volatile. Non-interest income was $8.0 million, compared to $6.4 million in the prior quarter. Excluding all non-core income adjustments noted above, core non-interest income1 was $9.3 million, compared to $9.1 million in the prior quarter. The increase was primarily related to higher commercial banking fees, partially offset by lower income from Trust fees. Non-interest expense was $40.6 million, a decrease of $1.1 million from the prior quarter. Core non-interest expense1 was $40.4 million, also a decrease of $1.1 million from the prior quarter. This was mainly driven by a $1.5 million decrease in professional fees, partially offset by a $0.4 million increase in advertising expense. Provision for income tax expense was $9.5 million, compared to $9.7 million for the prior quarter. The effective tax rate was 26.7%, compared to 28.0% in the prior quarter. The California single-sales factor apportionment law was adopted 2

during the quarter which resulted in an increase in the California state tax rate. A discrete tax benefit was recognized during the current quarter for the remeasurement of deferred tax assets reducing the quarterly effective tax rate. Going forward, the tax rate is expected to be 27.3%. The prior quarter effective tax rate was impacted by discrete tax items related to a city and state tax examination. Adjusted, the current quarter effective tax rate was 27.3% compared to 27.0% for the prior quarter. Balance Sheet Quarterly Summary Total assets were $8.6 billion at June 30, 2025, a $336.1 million or a 4% increase compared to $8.3 billion at March 31, 2025. On the last day of the quarter, the balance sheet was impacted by $112.3 million of temporary pension funding deposits that were withdrawn the following day. Adjusted, total assets were $8.5 billion, in line with our target for the quarter. Notable changes within individual balance sheet line items include a $177.6 million increase in securities and a $35.5 million increase in net loans receivable. On the liabilities side, on-balance sheet deposits increased by $321.2 million or $208.9 million when adjusted for the temporary deposits noted above. Off-balance sheet deposits decreased by $173.1 million in the quarter. Equity grew by $18.0 million. Total net loans receivable at June 30, 2025 were $4.7 billion, an increase of $35.5 million, or 0.8% for the quarter. A balanced increase in loans was primarily driven by a $34.2 million increase in multifamily loans, a $13.5 million increase in commercial and industrial loans, and a $13.1 million increase in commercial real estate loans, all in our identified growth portfolios. This was partially offset by a $11.0 million decrease in consumer solar loans, and a $11.8 million decrease in residential loans, both being non-growth portfolios. During the quarter, criticized or classified loans increased $13.9 million, largely related to the downgrades of four commercial and industrial loans totaling $9.7 million, the downgrade of one multifamily loan totaling $2.8 million, additional downgrades of small business loans totaling $1.0 million, and an increase of $2.1 million in residential and consumer substandard loans. This was partially offset by charge-offs of small business loans totaling $1.1 million, and an upgrade of one $0.1 million small business loan. Total on-balance sheet deposits at June 30, 2025 were $7.7 billion, an increase of $321.2 million, or 4.3%, during the quarter. Including accounts currently held off-balance sheet, deposits held by politically active customers, such as campaigns, PACs, advocacy-based organizations, and state and national party committees were $1.2 billion as of June 30, 2025, an increase of $136.5 million during the quarter. Non-interest-bearing deposits represented 38% of average total deposits and 36% of ending total deposits for the quarter, contributing to an average cost of total deposits of 162 basis points. Super-core deposits1 totaled approximately $4.2 billion, had a weighted average life of 18 years, and comprised 54% of total deposits. Total uninsured deposits were $3.9 billion, comprising 50% of total deposits. Nonperforming assets totaled $35.2 million, or 0.41% of period-end total assets at June 30, 2025, an increase of $1.3 million, compared with $33.9 million, or 0.41% on a linked quarter basis. The increase in nonperforming assets was primarily driven by a $2.4 million increase in residential non-accrual loans, partially offset by a $0.3 million decrease in commercial and industrial nonaccrual loans, a $0.3 million decrease in consumer solar nonaccrual loans, and a $0.5 million decrease in nonaccrual loans held for sale compared to the prior quarter. 3

During the quarter, the allowance for credit losses on loans increased $1.3 million to $59.0 million. The ratio of allowance to total loans was 1.25%, an increase of 2 basis points from 1.23% in the first quarter of 2025. This is primarily due to an increase of $2.3 million in reserves for one commercial and industrial loan, along with increases in provision related to the macroeconomic forecasts used in the CECL model. The loan associated with the increased reserve is a commercial and industrial business loan to an originator of consumer loans for renewable energy efficiency improvements. During the quarter, $2.5 million of debtor-in-possession (“DIP”) financing was put in place, a portion of which was advanced and increased our outstanding exposure from $8.3 million to $9.3 million as of June 30, 2025. Additionally, during the third quarter, the remainder of the DIP financing was advanced bringing the total exposure to $10.8 million as of the date of this earnings release. While there remains collateral value, the situation with this loan is fluid and could result in further reserves as the workout progresses. Capital Quarterly Summary As of June 30, 2025, the Common Equity Tier 1 Capital ratio was 14.13%, the Total Risk-Based Capital ratio was 16.43%, and the Tier 1 Leverage Capital ratio was 9.22%, compared to 14.27%, 16.61% and 9.22%, respectively, as of March 31, 2025. Stockholders’ equity at June 30, 2025 was $754.0 million, an increase of $18.0 million during the quarter. The increase in stockholders’ equity was primarily driven by $26.0 million of net income for the quarter and a $4.3 million improvement in accumulated other comprehensive loss due to the tax-effected mark-to-market on available for sale securities, offset by $9.7 million in share buybacks and $4.4 million in dividends paid at $0.14 per outstanding share. Tangible book value per share1 was $24.33 as of June 30, 2025 compared to $23.51 as of March 31, 2025. Tangible common equity1 improved to 8.60% of tangible assets, compared to 8.73% as of March 31, 2025.

2 Safe Harbor Statements FORWARD-LOOKING STATEMENTS Statements included in this presentation that are not historical in nature are intended to be, and are hereby identified as, forward-looking statements within the meaning of the Private Securities Litigation Reform Act, Section 21E of the Securities Exchange Act of 1934, as amended. Forward- looking statements generally can be identified through the use of forward-looking terminology such as “may,” “will,” “anticipate,” “aspire,” “should,” “would,” “believe,” “contemplate,” “expect,” “estimate,” “continue,” “in the future,” “may” and “intend,” as well as other similar words and expressions of the future. Forward-looking statements are subject to known and unknown risks, uncertainties and other factors, any or all of which could cause actual results to differ materially from the results expressed or implied by such forward-looking statements. These risks and uncertainties include, but are not limited to: 1. uncertain conditions in the banking industry and in national, regional and local economies in core markets, which may have an adverse impact on business, operations and financial performance; 2. deterioration in the financial condition of borrowers resulting in significant increases in credit losses and provisions for those losses; 3. deposit outflows and subsequent declines in liquidity caused by factors that could include lack of confidence in the banking system, a deterioration in market conditions or the financial condition of depositors; 4. changes in deposits, including an increase in uninsured deposits; 5. ability to maintain sufficient liquidity to meet deposit and debt obligations as they come due, which may require that the Company sell investment securities at a loss, negatively impacting net income, earnings and capital; 6. unfavorable conditions in the capital markets, which may cause declines in stock price and the value of investments; 7. negative economic and political conditions that adversely affect the general economy, housing prices, the real estate market, the job market, consumer confidence, the financial condition of borrowers and consumer spending habits, which may affect, among other things, the level of non- performing assets, charge-offs and provision expense; 8. fluctuations or unanticipated changes in the interest rate environment including changes in net interest margin or changes in the yield curve that affect investments, loans or deposits; 9. the general decline in the real estate and lending markets, particularly in commercial real estate in the Company’s market areas, and the effects of the enactment of or changes to rent-control and other similar regulations on multi-family housing; 10. potential implementation by the current presidential administration of a regulatory reform agenda that is significantly different from that of the prior presidential administration, impacting the rule making, supervision, examination and enforcement of the banking regulation agencies; 11. changes in U.S. trade policies and other global political factors beyond the Company’s control, including the imposition of tariffs, which raise economic uncertainty, potentially leading to slower growth and a decrease in loan demand; 12. the outcome of legal or regulatory proceedings that may be instituted against us; 13. inability to achieve organic loan and deposit growth and the composition of that growth; 14. composition of the Company’s loan portfolio, including any concentration in industries or sectors that may experience unanticipated or anticipated adverse conditions greater than other industries or sectors in the national or local economies in which the Company operates; 15. inaccuracy of the assumptions and estimates the Company makes and policies that the Company implements in establishing the allowance for credit losses; 16. changes in loan underwriting, credit review or loss reserve policies associated with economic conditions, examination conclusions, or regulatory developments; 17. any matter that would cause the Company to conclude that there was impairment of any asset, including intangible assets; 18. limitations on the ability to declare and pay dividends; 19. the impact of competition with other financial institutions, including pricing pressures and the resulting impact on results, including as a result of compression to net interest margin; 20. increased competition for experienced members of the workforce including executives in the banking industry; 21. a failure in or breach of operational or security systems or infrastructure, or those of third party vendors or other service providers, including as a result of unauthorized access, computer viruses, phishing schemes, spam attacks, human error, natural disasters, power loss and other security breaches; 22. increased regulatory scrutiny and exposure from the use of “big data” techniques, machine learning, and artificial intelligence; 23. a downgrade in the Company’s credit rating; 24. “greenwashing claims” against the Company and environmental, social, and governance ("ESG") products and increased scrutiny and political opposition to ESG and diversity, equity, and inclusion ("DEI") practices; 25. any unanticipated or greater than anticipated adverse conditions (including the possibility of earthquakes, wildfires, and other natural disasters) affecting the markets in which the Company operates; 26. physical and transitional risks related to climate change as they impact the business and the businesses that the Company finances; 27. future repurchase of the Company’s shares through the Company’s common stock repurchase program; and 28. descriptions of assumptions underlying or relating to any of the foregoing. Additional factors which could affect the forward-looking statements can be found in the Company’s Annual Reports on Form 10-K, Quarterly Reports on Form 10-Q, and Current Reports on Form 8-K filed with the SEC and available on the SEC's website at https://www.sec.gov/. The Company disclaims any obligation to update or revise any forward-looking statements contained in this release, which speak only as of the date hereof, whether as a result of new information, future events or otherwise, except as required by law. NON-GAAP FINANCIAL MEASURES This presentation contains certain non-GAAP financial measures including, without limitation, “Core Operating Revenue,” “Core Non-interest Expense,” “Tangible Common Equity,” “Average Tangible Common Equity,” “Core Efficiency Ratio,” “Core Net Income,” “Core ROAA,” and “Core ROATCE.” We believe these non-GAAP financial measures provide useful information to management and investors that is supplementary to our financial condition, results of operations and cash flows computed in accordance with GAAP. Specifically, we believe these non-GAAP financial measures (a) allow management and investors to better assess our performance by removing volatility that is associated with discrete items that are unrelated to our core business, and (b) enable a more complete understanding of factors and trends affecting our business. Non-GAAP financial measures, however, have inherent limitations, are not required to be uniformly applied, and are not audited. Accordingly, these non-GAAP financial measures should not be considered as substitutes for GAAP financial measures, and we strongly encourage investors to review the GAAP financial measures included in this presentation and not to place undue reliance on any single financial measure. In addition, because non-GAAP financial measures are not standardized, it may not be possible to compare the non-GAAP financial measures presented in this presentation with other companies’ non-GAAP financial measures having the same or similar names. As such, you should not view these disclosures as a substitute for results determined in accordance with GAAP, and they are not necessarily comparable to non-GAAP financial measures that other companies use. Reconciliations of non-GAAP financial disclosures to what we believe to be the most directly comparable GAAP measures found in this presentation are set forth in the final pages of this presentation and also may be viewed on the bank’s website, amalgamatedbank.com. You should assume that all numbers presented are unaudited unless otherwise noted.
