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.

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 at on the SEC’s archive site, here,) and its other filings with the SEC.
