3 Safe Harbor Statements cont. NON-GAAP FINANCIAL MEASURES This presentation refers to certain non-GAAP financial measures including, without limitation, “Core operating revenue,” “Core non-interest expense,” “Core non-interest income,” “Core net income,” “Tangible common equity,” “Average tangible common equity,” “Core return on average assets,” “Core return on average tangible common equity,” and “Core efficiency ratio.” Our management utilizes this information to compare our operating performance for December 31, 2023 versus certain periods in 2023 and 2022 and to prepare internal projections. We believe these non-GAAP financial measures facilitate making period-to-period comparisons and are meaningful indications of our operating performance. In addition, because intangible assets such as goodwill and other discrete items unrelated to our core business, which are excluded, vary extensively from company to company, we believe that the presentation of this information allows investors to more easily compare our results to those of other companies. The presentation of non-GAAP financial information, however, is not intended to be considered in isolation or as a substitute for GAAP financial measures. We strongly encourage readers to review the GAAP financial measures included in this release and not to place undue reliance upon 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 in this presentation with other companies’ non-GAAP financial measures having the same or similar names. Reconciliations of non-GAAP financial disclosures to comparable GAAP measures found in this release are set forth in the final pages of this presentation and also may be viewed on our website, amalgamatedbank.com. You should assume that all numbers presented are unaudited unless otherwise noted.
