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, our 2024 Guidance, and statements related to future loss/income (including projected non-interest income) of solar tax equity investments. These forward-looking statements are subject to known and unknown risks, uncertainties and other factors, many of which are beyond our control and 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: • uncertain conditions in the banking industry and in national, regional and local economies in our core markets, which may have an adverse impact on our business, operations and financial performance; • deterioration in the financial condition of borrowers resulting in significant increases in loan losses and provisions for those losses • 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; • changes in our deposits, including an increase in uninsured deposits; • unfavorable conditions in the capital markets, which may cause declines in our stock price and the value of our investments; • 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 our borrowers and consumer spending habits, which may affect, among other things, the level of non- performing assets, charge-offs and provision expense; • the rate of growth (or lack thereof) in the economy and employment levels, as well as general business and economic conditions, coupled with the risk that adverse conditions may be greater than anticipated in the markets that we serve; • continued fluctuation of the interest rate environment including changes in net interest margin or changes that affect the yield curve on investments; • potential deterioration in real estate collateral values • changes in legislation, regulation, public policies, or administrative practices impacting the banking industry, including increased regulation and FDIC assessments in the aftermath of the Silicon Valley and Signature Bank failures • the outcome of any legal proceedings that may be instituted against us • fluctuations or unanticipated changes in interest rates on loans or deposits or that affect the yield curve; • our inability to maintain the historical growth rate of our loan portfolio; • changes in loan underwriting, credit review or loss reserve policies associated with economic conditions, examination conclusions, or regulatory developments; • the impact of competition with other financial institutions, many of which are larger and have greater resources, and fintechs, as well as changes in the competitive environment; • any matter that would cause us to conclude that there was impairment of any asset, including intangible assets; • the risk that the preliminary financial information reported herein and our current preliminary analysis could be different when our review is finalized; • increased competition for experienced members of the workforce including executives in the banking industry; • our ability to meet heightened regulatory and supervisory requirements; • our ability to grow and retain low-cost core deposits and retain large, uninsured deposits; • inability to comply with regulatory capital requirements, including those resulting from changes to capital calculation methodologies, required capital maintenance levels or regulatory requests or directives; • risks associated with litigation, including the applicability of insurance coverage; • the risk of not achieving anticipated cost savings related to reduction in the number of branch locations and other expense areas; • a failure in or breach of our 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; • a downgrade in our credit rating; • increased political opposition to Environmental, Social and Governance (“ESG”) practices; • recessionary conditions; • the ongoing economic effects of the COVID-19 pandemic • volatile credit and financial markets both domestic and foreign; • unexpected challenges related to our executive officer retention; and • physical and transitional risks related to climate change as they impact our business and the businesses that we finance. Additional factors which could affect the forward-looking statements can be found in our Annual Report 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 www.sec.gov/. We disclaim any obligation to update or revise any forward-looking statements contained in this presentation, which speak only as of the date hereof, or to update the reasons why actual results could differ from those contained in or implied by such statements, 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.
