Forward-Looking Statements This presentation and our other communications may contain forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Rule 175 promulgated thereunder, and Section 21E of the Securities Exchange Act of 1934, as amended, and Rule 3b-6 promulgated thereunder, which statements involve inherent risks and uncertainties. Forward-looking statements convey our expectations, intentions, or forecasts about future events, circumstances, results, or aspirations. All forward-looking statements are subject to assumptions, risks, and uncertainties, which may change over time and many of which are beyond our control. You should not rely on any forward-looking statement as a prediction or guarantee about the future. Our actual future objectives, strategies, plans, prospects, performance, condition, or results may differ materially from those set forth in any forward-looking statement. Some of the factors that may cause actual results or other future events, circumstances, or aspirations to differ from those in forward-looking statements are described in annual, quarterly and other applicable documents that are filed or furnished with the U.S. Securities and Exchange Commission (“SEC”). In addition to such factors that have been disclosed previously: risks related to current or future tariffs or trade restrictions, sanctions and other trade policies and the impact to UMB or its customers; macroeconomic and adverse developments and uncertainties related to the collateral effects of the collapse of, and challenges for, domestic and international banks, including the impacts to the U.S. and global economies; sustained levels of high inflation and the potential for an economic recession; and impacts related to or resulting from instability with respect to geopolitical developments, including in Venezuela, the Middle East and Russia’s military action in Ukraine, such as the broader impacts to financial markets and the global macroeconomic and geopolitical environments, may also cause actual results or other future events, circumstances, or aspirations to differ from our forward-looking statements. Any forward-looking statement made by us or on our behalf speaks only as of the date that it was made. We do not undertake to update any forward-looking statement to reflect the impact of events, circumstances, or results that arise after the date that the statement was made, except to the extent required by applicable securities laws. You, however, should consult disclosures (including disclosures of a forward-looking nature) that we may make in any subsequent documents that are filed or furnished with the SEC. Any statements about UMB Financial Corporation’s (“UMB”) plans, objectives, expectations, strategies, beliefs, or future performance or events constitute forward-looking statements. Such statements are generally identified as those that include words or phrases such as “believes,” “expects,” “anticipates,” “plans,” “objective,” or similar expressions or future or conditional verbs such as “will,” “would,” “should,” “could,” “might,” “may,” or similar expressions. Forward-looking statements involve known and unknown risks, uncertainties, assumptions, estimates, and other important factors that change over time and could cause actual results to differ materially from any results, performance, or events expressed or implied by such forward-looking statements. These forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those projected. Further information regarding UMB and factors which could affect the forward-looking statements contained herein can be found in UMB’s Form 10-K for the year ended December 31, 2025 (and which is available on the SEC’s archive site, here) and its other filings with the SEC.

Non-GAAP Reconciliations The following are non-GAAP measures used from time to time. To the extent a non-GAAP measure is used in this presentation, a reconciliation to such measure’s closest GAAP equivalent is provided below. This information supplements the results that are reported according to GAAP and should not be viewed in isolation from, or as a substitute for, GAAP results. UMB believes that these measures may be useful to investors because they adjust for items that management does not believe reflect the Company’s fundamental operating performance. Definition and calculation for each metric shown below tables. Net Operating Income Available to Common Shareholders Net operating income available to common shareholders is defined as GAAP net income available to common shareholders, adjusted to exclude acquisitions and severance expenses, Day 1 acquisition provision expense, if any, the FDIC special assessment, and the cumulative tax impact of these adjustments.
