We believe this metric is meaningful as it provides information on loan yields excluding the impacts of hedge-related interest rate risk management programs GAAP to Non-GAAP Reconciliation 18

(1) Favorable (unfavorable) impact; (2) Impact to EPS reflected on a fully diluted basis; (3) In November 2023, the FDIC issued a final rule implementing a special assessment on insured depository institutions to recover the loss to the FDIC’s deposit insurance fund (DIF) associated with protecting uninsured depositors following the 2023 closures of Silicon Valley Bank and Signature Bank. KeyCorp recorded the initial loss estimate related to the special assessment during the fourth quarter of 2023. Amounts reflected in this table represent adjustments from initial estimates based on quarterly invoices received from the FDIC; (4) Earnings per share may not foot due to rounding Selected Items Impact on Earnings $ in millions, except per share amounts After-tax at marginal rate(1) Quarter to date results Pretax(1) Amount Net Income EPS(2)(4) Three months ended September 30, 2026 No items $ — $ — $ — Three months ended June 30, 2026 No items — — — Three months ended March 31, 2026 No items — — — Three months ended December 31, 2025 FDIC special assessment (other expense)(3) 21 16 0.01 Three months ended September 30, 2025 FDIC special assessment (other expense)(3) 5 4 — Year to date results Nine months ended September 30, 2026 No items $ — $ — $ — Nine months ended September 30, 2025 FDIC special assessment (other expense)(3) 5 4 — Selected Items Impact on Earnings 19

This presentation 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, 2025, 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. Non-GAAP Measures. This presentation 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 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). Forward-Looking Non-GAAP Measures. From time to time we may discuss forward-looking non-GAAP financial measures. We are unable to provide a reconciliation of forward-looking non-GAAP financial measures to their most directly comparable GAAP financial measures because we are unable to provide, without unreasonable effort, a meaningful or accurate calculation or estimation of amounts that would be necessary for the reconciliation due to the complexity and inherent difficulty in forecasting and quantifying future amounts or when they may occur. Such unavailable information could be significant for future results. Annualized Data. 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. Taxable-Equivalent. 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. Earnings Per Share Equivalent. 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, unless otherwise specified, with this then being the amount used to calculate the earnings per share equivalent.
