ITEM 7.01. Regulation FD Disclosure

On May 9, 2012, FTI Consulting, Inc. (“FTI Consulting”) held a conference call relating to the press release issued on May 9, 2012 announcing financial results for the first quarter ended March 31, 2012. The full text of the transcript of the conference call is furnished as Exhibit 99.1 hereto and incorporated by reference herein.

The transcript includes information regarding adjusted EBITDA, adjusted segment EBITDA and adjusted earnings per diluted share. We define adjusted EBITDA as consolidated operating income before depreciation, amortization of intangible assets and special charges (“Adjusted EBITDA”). We define adjusted segment EBITDA as a segment’s share of consolidated operating income before depreciation, amortization of intangible assets and special charges (“Adjusted Segment EBITDA”). We define adjusted earnings per diluted share as earnings per diluted share excluding the per share net impact of any special charges and any loss on early extinguishment of debt that were incurred in that period (“Adjusted EPS”). Although Adjusted EBITDA, Adjusted Segment EBITDA and Adjusted EPS are not measures of financial condition or performance determined in accordance with generally accepted accounting principles (“GAAP”), we believe that these measures can be a useful operating performance measure for evaluating our results of operations as compared from period-to-period and as compared to our competitors. Adjusted EBITDA, Adjusted Net Income and Adjusted EPS are common alternative measures of operating performance which may be used by investors, financial analysts and rating agencies to value and compare the financial performance of companies in our industry. We use Adjusted EBITDA and Adjusted Segment EBITDA to evaluate and compare the operating performance of our segments. Adjusted EBITDA, Adjusted Segment EBITDA and Adjusted EPS are not defined in the same manner by all companies and may not be comparable to other similarly titled measures of other companies unless the definition is the same. These non-GAAP measures should be considered in addition to, but not as a substitute for or superior to, the information contained in our statements of income. Reconciliations of operating income to Adjusted EBITDA, segment operating income to Adjusted Segment EBITDA and earnings per diluted share to Adjusted EPS are included in the financial tables that accompanied FTI Consulting’s press release, which was filed as Exhibit 99.1 to the Current Report on Form 8-K dated and filed with the Securities and Exchange Commission on May 10, 2012.

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.
