STIFEL REPORTS FIRST QUARTER 2014 FINANCIAL RESULTS

ST. LOUIS, May 8, 2014 – Stifel Financial Corp. (NYSE: SF) today reported net income from continuing operations of $48.0 million, or $0.63 per diluted common share on net revenues of $546.7 million for the three months ended March 31, 2014, compared with net income from continuing operations of $14.9 million, or $0.22 per diluted common share, on net revenues of $438.6 million for the first quarter of 2013.

For the three months ended March 31, 2014, the Company reported non-GAAP net income from continuing operations of $52.0 million, or $0.69 per diluted common share. These non-GAAP results exclude merger-related expenses associated with the Company’s recent acquisitions for a total of $4.1 million (after-tax). A reconciliation of the Company’s GAAP results to these non-GAAP measures is discussed below under “Non-GAAP Financial Measures.”

Chairman’s Comments

“During the first quarter we delivered solid results. Contributions from Global Wealth Management and Institutional Group drove a 25% year-over-year increase in total net revenues. We continue to attract experienced financial advisors, and total client assets reached a record $168 billion. Investment banking produced nice results driven by both advisory and equity transactions. In the quarter, we continued to benefit from our expansion in the Institutional Group,” said Ronald J. Kruszewski, Chairman, President, and CEO of Stifel Financial Corp.

Kruszewski continued, “On April 3, 2014 we closed the previously announced acquisition of De La Rosa & Co., a California-based public finance investment banking boutique. We have integrated this impressive group into our current platform and are excited about their contribution to Stifel’s fixed income capabilities going forward.”

“Furthermore, today we announced the acquisition of Oriel Securities, which will significantly expand Stifel’s depth, expertise, and reach in London, a vital global financial center. We are excited to partner with Oriel to grow our business internationally.”

The increase in net revenues from the first quarter of 2013 is primarily attributable to (1) growth in asset management and service fees; (2) increased net interest revenues; and (3) an increase in commission revenues, offset primarily by (1) a decrease in investment gains (included in other revenues); and (2) a decline in principal transaction revenues.

The increase in net revenues from the first quarter of 2013 was primarily attributable to (1) an

increase in advisory fees; (2) an increase in equity capital raising revenues; and (3) higher institutional brokerage revenues, offset by a reduction in other revenues as a result of gains recorded on the investment in Knight Capital during the first quarter of 2013.

Non-GAAP Financial Measures

The Company utilized non-GAAP calculations of presented net revenues, compensation and benefits, non-compensation operating expenses, income before income taxes, provision for income taxes, net income, compensation and non-compensation operating expense ratios, pre-tax margin and diluted earnings per share as additional measures to aid in understanding and analyzing the Company’s financial results for the three months ended March 31, 2014. 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. These non-GAAP amounts exclude certain compensation and non-compensation operating expenses associated with the recent acquisitions.

A limitation of utilizing these non-GAAP measures of net revenues, compensation and benefits, non-compensation operating expenses, income before income taxes, provision for income taxes, net income, compensation and non-compensation operating expenses ratios, pre-tax margin and diluted earnings per share is that the GAAP accounting effects of these merger-related 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 of net revenues, compensation and benefits, non-compensation operating expenses, income before income taxes, provision for income taxes, net income, compensation and non-compensation operating expense ratios, pre-tax margin and diluted earnings per share and the same respective non-GAAP measures of the Company’s financial performance should be considered together.

The following table provides details with respect to reconciling net revenues, compensation and benefits, non-compensation operating expenses, income before income taxes, provision for income taxes, net income, compensation and non-compensation operating expense ratios, pre-tax margin and diluted earnings per share on a GAAP basis for the three months ended March 31, 2014 to the aforementioned expenses on a non-GAAP basis for the same period.
