Forward looking statements & non-GAAP Forward looking statements: This presentation contains estimates, predictions, opinions, projections and other "forward-looking statements" as that phrase is defined in the Private Securities Litigation Reform Act of 1995. Such statements include, without limitation, references to the Company's predictions or expectations of future business or financial performance as well as its goals and objectives for future operations, financial and business trends, business prospects, and management's outlook or expectations for earnings, revenues, expenses, capital levels, liquidity levels, asset quality or other future financial or business performance, strategies or expectations. The words “believe,” “expect,” “anticipate,” “plan,” “estimate,” “target,” “project” and similar expressions, among others, generally identify forward-looking statements. Such forward- looking statements are based on various assumptions (some of which may be beyond the Company's control) and are subject to significant risks and uncertainties (which change over time) and other factors, including the impacts related to or resulting from bank failures and other economic and industry volatility, including potential increased regulatory requirements and costs and potential impacts to macroeconomic conditions, the uncertain effects of geopolitical instability, armed conflicts, public health crises, inflation, interest rates and actions taken in response thereto on our business, results of operations, capital and liquidity, which could cause actual results to differ materially from those currently anticipated. Such risks and uncertainties are discussed in detail in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, and other documents filed by the Company with the Securities and Exchange Commission from time to time. We caution readers not to place undue reliance on any such forward-looking statements, which speak only as of the date on which they are made, and the Company disclaims any duty to revise or update any forward-looking statement, whether written or oral, that may be made from time to time by or on behalf of the Company for any reason, except as specifically required by law. As used in this presentation, the terms "WSFS", "the Company", "registrant", "we", "us", and "our" mean WSFS Financial Corporation and its subsidiaries, on a consolidated basis, unless the context indicates otherwise. Non-GAAP financial measures: This presentation contains financial measures determined by methods other than in accordance with accounting principles generally accepted in the United States (“GAAP”). These non-GAAP measures include core earnings per share (“EPS”), core efficiency ratio, pre-provision net revenue (“PPNR”), PPNR to average assets ratio, core PPNR to average assets ratio, core net revenue, core PPNR, core return on assets (“ROA”), core net interest income, core noninterest expense, tangible common book value (“TBV”), TBV excluding AOCI, tangible common equity (“TCE”), tangible assets, tangible equity, return on tangible common equity (“ROTCE”), core ROTCE, core fee revenue, core fee revenue ratio, effective AOCI, and coverage ratio including the estimated remaining credit marks and excluding HTM securities. The Company’s management believes that these non-GAAP measures provide a greater understanding of ongoing operations, enhance comparability of results of operations with prior periods and show the effects of significant gains and charges in the periods presented. The Company’s management believes that investors may use these non-GAAP measures to analyze the Company’s financial performance without the impact of unusual items or events that may obscure trends in the Company’s underlying performance. This non-GAAP data should be considered in addition to results prepared in accordance with GAAP, and is not a substitute for, or superior to, GAAP results. For a reconciliation of these non-GAAP measures to their comparable GAAP measures, see the Appendix. 2
