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.
