Cautionary Note Regarding Forward-Looking Statements
This Current Report on Form 8-K 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. Any statements about UMB’s, El Dorado’s or the combined company’s 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,” “trend,” “objective,” “continue,” 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. Such forward-looking statements include but are not limited to statements about the benefits of the Merger, including future financial and operating results, the combined company’s plans, objectives, expectations and intentions, and other statements that are not historical facts.
These forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially from those projected. In addition to factors previously disclosed in UMB’s reports filed with the SEC, the following factors, among others, could cause actual results to differ materially from forward-looking statements or historical performance: the occurrence of any event, change, or other circumstance that could give rise to a right to terminate the Merger Agreement; the outcome of any legal proceedings that may be instituted against UMB or El Dorado; the possibility that the Merger does not close when expected or at all because required regulatory, stockholder, or other approvals and other conditions to closing are not received or satisfied on a timely basis or at all
(and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of the Merger); the risk that the benefits from the Merger may not be fully realized or may take longer to realize than expected, including as a result of changes in, or problems arising from, general economic and market conditions, interest and exchange rates, monetary policy, laws and regulations and their enforcement, and the degree of competition in the geographic and business areas in which UMB and El Dorado operate; instability in global economic conditions and geopolitical matters and impacts related to or resulting from instability in the Middle East and Russia’s military action in Ukraine; changes in U.S. trade policies, including the imposition of tariffs and retaliatory tariffs; the impact of pandemics and other catastrophic events or disasters on the global economy and financial market conditions and UMB’s business, results of operations, and financial condition; the impacts related to or resulting from bank failures and other volatility, including potential increased regulatory requirements and costs, such as Federal Deposit Insurance Corporation (the “FDIC”) special assessments, long-term debt requirements and heightened capital requirements, and potential impacts to macroeconomic conditions, which could affect the ability of depository institutions, including UMB Bank, to attract and retain depositors and to borrow or raise capital; unexpected outflows of uninsured deposits which may require UMB to sell investment securities at a loss; changing interest rates which could negatively impact the value of UMB’s portfolio of investment securities; the loss of value of UMB’s investment portfolio which could negatively impact market perceptions of UMB and could lead to deposit withdrawals; the effects of social media on market perceptions of UMB and banks generally; cybersecurity risks; uncertainty in U.S. fiscal and monetary policy, including the interest rate policies of the Board of Governors of the Federal Reserve System (the “Federal Reserve”); volatility and disruptions in global capital, foreign exchange and credit markets; movements in interest rates; changes in policies and standards for regulatory review of bank mergers; the nature, extent, timing, and results of governmental actions, examinations, reviews, reforms, regulations, and interpretations, including those related to the Dodd-Frank Wall Street Reform and Consumer Protection Act and the Basel III regulatory capital reforms, as well as those involving the SEC, the Office of the Comptroller of the Currency, the Federal Reserve, the FDIC, the Consumer Financial Protection Bureau and state-level regulators; the ability to promptly and effectively integrate the businesses of UMB and El Dorado; the possibility that the Merger may be more expensive to complete than anticipated, including as a result of unexpected factors or events; reputational risk and potential adverse reactions of UMB’s or El Dorado’s customers, employees or other business partners, including those resulting from the announcement or completion of the Merger; the dilution caused by UMB’s issuance of additional shares of its capital stock in connection with the Merger; and the diversion of management’s attention and time from ongoing business operations and opportunities to merger-related matters.
These factors are not necessarily all of the factors that could cause UMB’s, El Dorado’s or the combined company’s actual results, performance, or achievements to differ materially from those expressed in or implied by any of the forward-looking statements. Other factors, including unknown or unpredictable factors, also could harm UMB’s, El Dorado’s or the combined company’s results.
All forward-looking statements attributable to UMB or persons acting on UMB’s behalf are expressly qualified in their entirety by the cautionary statements set forth above. Forward-looking statements speak only as of the date they are made, and UMB does not undertake or assume any obligation to update publicly any of these statements to reflect actual results, new information or future events, changes in assumptions, or changes in other factors affecting forward-looking statements, except to the extent required by applicable law. If UMB updates one or more forward-looking statements, no inference should be drawn that UMB will make additional updates with respect to those or other forward-looking statements. Further information regarding UMB and factors which could affect the forward-looking statements contained herein can be found in UMB’s Annual Report on Form 10-K for the fiscal year ended December 31, 2025 (available at https://www.sec.gov/Archives/edgar/data/101382/000119312526076496/umbf-20251231.htm) and its other filings with the SEC.

The combination of companies will significantly strengthen UMB’s physical and brand presence on the West Coast.
“This milestone is a significant leap forward for our retail footprint and overall presence in California and expands our UMB branch network into Nevada,” said UMB Financial Corporation Chairman and CEO Mariner Kemper. “Since growing our California presence with the HTLF acquisition in 2025, the region’s vibrancy, complementary customer needs and overall business growth opportunities have made it incredibly compelling for our next phase of expansion.”

Under the terms of the agreement, which were unanimously approved by the boards of directors of each company, El Dorado shareholders will receive a fixed exchange ratio of 13.553 shares of UMBF common stock, plus an additional $1,958.88 in cash for each outstanding share of El

Dorado stock. Following completion of this contemplated transaction, former El Dorado shareholders are expected to collectively own approximately 2% of the combined company.
UMB is deeply invested in the communities in which it does business, providing support through products, services, and investments as well as corporate and associate giving.
