Forward-looking statements are typically identified by words such as “believe,” “seek,” “expect,” “anticipate,” “intend,” “target,” “estimate,” “continue,” “positions,” “plan,” “predict,” “project,” “forecast,” “guidance,” “goal,” “objective,” “prospects,” “possible,” “potential,” “strategy,” “opportunities,” or “trends,” by future conditional verbs such as “assume,” “will,” “would,” “should,” “could” or “may”, or by variations of such words or by similar expressions. These forward-looking statements are based on assumptions that involve risks and uncertainties, which are subject to change based on various important factors (some of which are beyond KeyCorp’s control.) Actual results may differ materially from current projections. Actual outcomes may differ materially from those expressed or implied as a result of the factors described under “Forward-looking Statements” and “Risk Factors” in KeyCorp’s Annual Report on Form 10-K for the year ended December 31, 2021, and in other filings of KeyCorp with the Securities and Exchange Commission (the “SEC”). Such forward-looking statements speak only as of the date they are made, and we undertake no obligation to update any forward-looking statement to reflect events or circumstances after that date or to reflect the occurrence of unanticipated events. For additional information regarding KeyCorp, please refer to our SEC filings available at www.key.com/ir. Annualized, pro forma, projected and estimated numbers are used for illustrative purpose only, are not forecasts and may not reflect actual results. This presentation also includes certain non-GAAP financial measures related to “tangible common equity,” “cash efficiency ratio,” and “pre-provision net revenue.” Although Key has procedures in place to ensure that these measures are calculated using the appropriate GAAP or regulatory components, they have limitations as analytical tools and should not be considered in isolation, or as a substitute for analysis of results under GAAP. For more information on these calculations and to view the reconciliations to the most comparable GAAP measures, please refer to the appendix of this presentation, or page 42 of our Form 10-Q dated March 31, 2022.
