Q&A

Disclaimer 17 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, 2020. 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. Statements about the effects of the COVID-19 pandemic on the Company’s business, results, financial position and liquidity may constitute forward-looking statements and are subject to the risk that the actual impact may differ, possibly materially, from what is currently expected. Use of Non-GAAP Financial Measures The Company utilized certain non-GAAP calculations as additional measures to aid in understanding and analyzing the Company’s financial results for the three and nine months ended September 30, 2021. Specifically, the Company believes that the non-GAAP measures provide useful information by excluding certain items that may not be indicative of the Company’s core operating results and business outlook. The Company believes that these non-GAAP measures will allow for a better evaluation of the operating performance of the business and facilitate a meaningful comparison of the Company’s results in the current period to those in prior and future periods. Reference to these non-GAAP measures should not be considered as a substitute for results that are presented in a manner consistent with GAAP. These non-GAAP measures are provided to enhance investors' overall understanding of the Company’s current financial performance. The non-GAAP financial information should be considered in addition to, not as a substitute for or as being superior to, operating income, cash flows, or other measures of financial performance prepared in accordance with GAAP. These non-GAAP measures primarily exclude expenses which management believes are, in some instances, non-recurring and not representative of ongoing business. A limitation of utilizing these non-GAAP measures is that the GAAP accounting effects of these charges do, in fact, reflect the underlying financial results of the Company’s business and these effects should not be ignored in evaluating and analyzing its financial results. Therefore, the Company believes that GAAP measures and the same respective non-GAAP measures of the Company’s financial performance should be considered together.
