Disclaimer Forward-Looking Statements This presentation may contain “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995 that involve significant risks, assumptions, and uncertainties, including statements relating to the market opportunity and future business prospects of Stifel Financial Corp., as well as Stifel, Nicolaus & Company, Incorporated and its subsidiaries (collectively, “SF” or the “Company”). These statements can be identified by the use of the words “may,” “will,” “should,” “could,” “would,” “plan,” “potential,” “estimate,” “project,” “believe,” “intend,” “anticipate,” “expect,” and similar expressions. All statements not dealing with historical results are forward-looking and are based on various assumptions. The forward-looking statements are subject to risks and uncertainties that could cause actual results to differ materially from those expressed in or implied by the statements. For information about the risks and important factors that could affect the Company’s future results, financial condition and liquidity, see “Risk Factors” in Part I of the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. Forward-looking statements speak only as to the date they are made. The Company disclaims any intent or obligation to update forward-looking statements to reflect circumstances or events that occur after the date the forward-looking statements are made. Use of Non-GAAP Financial Measures The Company prepares its Consolidated Financial Statements using accounting principles generally accepted in the United States (U.S. GAAP). The Company may disclose certain “non-GAAP financial measures” in the course of its earnings releases, earnings conference calls, financial presentations and otherwise. The Securities and Exchange Commission defines a “non-GAAP financial measure” as a numerical measure of historical or future financial performance, financial position, or cash flows that is subject to adjustments that effectively exclude, or include, amounts from the most directly comparable measure calculated and presented in accordance with U.S. GAAP. Non-GAAP financial measures disclosed by the Company are provided as additional information to analysts, investors and other stakeholders in order to provide them with greater transparency about, or an alternative method for assessing the Company’s financial condition or operating results. These measures are not in accordance with, or a substitute for U.S. GAAP, and may be different from or inconsistent with non-GAAP financial measures used by other companies. Whenever the Company refers to a non-GAAP financial measure, it will also define it or present the most directly comparable financial measure calculated and presented in accordance with U.S. GAAP, along with a reconciliation of the differences between the non-GAAP financial measure it references and such comparable U.S. GAAP financial measure.
