Fourth Quarter 2013

Global Wealth Management

For the quarter ended December 31, 2013, the Global Wealth Management segment generated record pre-tax operating income of $79.0 million, compared with $68.7 million in the fourth quarter of 2012 and $72.1 million in the third quarter of 2013. Net revenues for the quarter were a record $292.8 million, compared with $253.8 million in the fourth quarter of 2012, and $274.7 million in the third quarter of 2013. The increase in net revenues from the fourth quarter of 2012 is primarily attributable to (1) growth in asset management and service fees; (2) an increase in commission revenues; and (3) increased net interest revenues.

Institutional Group

For the quarter ended December 31, 2013, the Institutional Group segment generated record pre-tax operating income of $48.6 million, compared with $21.7 million in the fourth quarter of 2012 and $35.0 million in the third quarter of 2013. Net revenues for the quarter were a record $267.3 million, compared with $160.7 million in the fourth quarter of 2012 and $205.1 million in the third quarter of 2013. The increase in net revenues from the fourth quarter of 2012 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 fourth quarter of 2012. Net revenue growth, on a year-over-year basis, is attributable to the acquisitions of KBW and the Knight Capital Fixed Income business and, to a lesser extent, Miller Buckfire.

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 and twelve months ended December 31, 2013. 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 compensation expense related to the granting of stock awards with no continuing service requirement issued as retention as part of the acquisitions of the Knight Capital Fixed Income business and KBW and certain compensation and non-compensation operating expenses associated with the acquisitions of KBW, Miller Buckfire, the Knight Capital Fixed Income business, and the U.S. tax benefit arising out of the Company’s investment in SN Canada.

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 and twelve months ended December 31, 2013 to the aforementioned expenses on a non-GAAP basis for the same period.
