On February 2, 2015, FTI Consulting, Inc. (“FTI Consulting”) issued its press release (the “Press Release”) reporting preliminary unaudited revenues and adjusted fully-diluted earnings per share (“Adjusted EPS”) for the year ended December 31, 2014 and preliminary guidance for the year ending December 31, 2015. The full text of the Press Release is set forth in Exhibit 99.1 and is incorporated by reference herein.

We define “Adjusted Net Income” and Adjusted EPS as net income and adjusted fully-diluted earnings per share, respectively, excluding the impact of remeasurement of acquisition-related contingent consideration, special charges, goodwill impairment charges and losses on early extinguishment of debt. We use Adjusted Net Income for the purpose of calculating Adjusted EPS. Adjusted Net Income and Adjusted EPS are not measures of financial condition or performance determined in accordance with generally accepted accounting principles (“GAAP”). FTI Consulting uses Adjusted EPS to assess total FTI Consulting operating performance on a consistent basis. FTI Consulting believes that this non-GAAP measure, when considered together with its GAAP financial results, provides management and investors with a more complete understanding of its business operating results, including underlying trends, by excluding the effects of remeasurement of acquisition-related contingent consideration, special charges, goodwill impairment charges and losses on early extinguishment of debt. Non-GAAP financial measures are not defined in the same manner by all companies and may not be comparable to other similarly titled measures of other companies. Non-GAAP financial measures should be considered in addition to, but not as a substitute for or superior to, the information contained in FTI Consulting’s Consolidated Statements of Comprehensive Income (Loss). The reconciliation of the GAAP to non-GAAP financial measure is included in the Press Release.

The information included herein, including Exhibit 99.1 furnished herewith, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be incorporated by reference into any filing pursuant to the Securities Act of 1933, as amended, or the Exchange Act, regardless of any incorporation by reference language in any such filing, except as expressly set forth by specific reference in such filing.

99.1 Press Release dated February 2, 2015, of FTI Consulting, Inc.
