3 Safe Harbor Statements cont. 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.
