Forward-looking Statements and Additional Information This communication contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 including, but not limited to, KeyCorp’s expectations or predictions of future financial or business performance or conditions. 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, 2022, Quarterly Report on Form 10-Q for the quarter ended March 31, 2023, 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” and “cash efficiency ratio.” 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 47 of our Form 10-Q dated March 31, 2023. Certain income or expense items may be expressed on a per common share basis. This is done for analytical and decision-making purposes to better discern underlying trends in total consolidated earnings per share performance excluding the impact of such items. When the impact of certain items is disclosed separately, the after-tax amount is computed using the marginal tax rate, with this then being the amount used to calculate the earnings per share equivalent.
