Adjusted CET1 ratio is a non-GAAP measure and is calculated based on Common Equity Tier 1 capital, inclusive of the AOCI impact from securities and pension, divided by risk weighted assets. We believe this non-GAAP measure provides useful information in light of the potential for change in the regulatory capital framework; (2) Loan Yields Excluding Impact from Hedges is a non-GAAP metric and is calculated by excluding losses realized on derivatives which hedge the interest rate risk of our loans. We believe this metric is meaningful as it provides information on loan yields excluding the impacts of hedge-related interest rate risk management programs Loan Yields Excluding Impact from Hedges(2) 2Q23 3Q23 4Q23 1Q24 2Q24 Loan Yield 5.26 % 5.41 % 5.51 % 5.61 % 5.66 % Subtract: Loan Yield Impact of Realized Hedge Gains/(Losses) (0.82) % (0.86) % (0.84) % (0.78) % (0.73) % Loan Yield Excluding Impact from Hedges 6.08 % 6.27 % 6.35 % 6.39 % 6.39 %

KeyCorp recorded the initial loss estimate related to the special assessment during the fourth quarter of 2023. In late February 2024, the FDIC provided updated estimates on the uninsured deposit losses and recoverable assets related to the 2023 closures of Silicon Valley Bank and Signature Bank. KeyCorp recorded the additional expense related to the revised special assessment during the first quarter of 2024. In June 2024, Key received its quarterly invoice from the FDIC which included amounts due under the special assessment. As such, Key recorded an additional expense in the second quarter of 2024 to true-up initial estimates to the invoiced amount.

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, 2023, and in subsequent 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. This document contains GAAP financial measures and non-GAAP financial measures where management believes it to be helpful in understanding Key’s results of operations or financial position. Where non-GAAP financial measures are used, the comparable GAAP financial measure, as well as the reconciliation to the comparable GAAP financial measure, can be found in in the appendix to this presentation, the financial supplement, or the press release related to this presentation, all of which can be found on Key’s website (www.key.com/ir). Certain returns, yields, performance ratios, or quarterly growth rates are presented on an “annualized” basis. This is done for analytical and decision-making purposes to better discern underlying performance trends when compared to full-year or year-over-year amounts. Income from tax-exempt earning assets is increased by an amount equivalent to the taxes that would have been paid if this income had been taxable at the federal statutory rate. This adjustment puts all earning assets, most notably tax-exempt municipal securities, and certain lease assets, on a common basis that facilitates comparison of results to results of peers. 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 income or expense 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.
