Cautionary Note about Forward-Looking Statements This presentation includes "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended (the “Securities Act”), and Section 21E of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), that involve uncertainties and risks. Forward-looking statements include statements concerning our plans, objectives, goals, strategies, future events, future revenues, future results and performance, future capital allocations and expenditures, expectations, plans or intentions relating to acquisitions, share repurchases and other matters, business trends, new, or changes to, laws and regulations, including the 2017 U.S. Tax Cuts and Jobs Act (the “2017 Tax Act”), and other information that is not historical, including statements regarding estimates of our future financial results. When used in this presentation, words such as "anticipates," "estimates," "expects," “goals,” "intends," "believes,” "forecasts,” “objectives” and variations of such words or similar expressions are intended to identify forward-looking statements. All forward-looking statements, including, without limitation, estimates of our future financial results, are based upon our expectations at the time we make them and various assumptions. Our expectations, beliefs and projections are expressed in good faith, and we believe there is a reasonable basis for them. However, there can be no assurance that management's expectations, beliefs or estimates will be achieved, and the Company's actual results may differ materially from our expectations, beliefs and estimates. The Company has experienced fluctuating revenues, operating income and cash flow in prior periods and expects that this will occur from time to time in the future. Other factors that could cause such differences include declines in demand for, or changes in, the mix of services and products that we offer, the mix of the geographic locations where our clients are located or where services are performed, fluctuations in the price per share of our common stock, adverse financial, real estate or other market and general economic conditions, and other future events, which could impact each of our segments differently and could be outside our control, the pace and timing of the consummation and integration of past and future acquisitions, the Company's ability to realize cost savings and efficiencies, competitive and general economic conditions, retention of staff and clients, new laws and regulations, or changes thereto, including the 2017 Tax Act, and other risks described under the heading "Part I, Item 1A Risk Factors" in the Company's Annual Report on Form 10-K for the year ended December 31, 2017, filed with the Securities and Exchange Commission (“SEC”) and in the Company's other filings with the SEC, including the risks set forth under "Risks Related to Our Reportable Segments" and "Risks Related to Our Operations.” We are under no duty to update any of the forward-looking statements to conform such statements to actual results or events and do not intend to do so.

End NotesFTI Consulting Non-GAAP Financial Measures In this presentation, we sometimes use information derived from consolidated and segment financial information that may not be presented in our financial statements or prepared in accordance with generally accepted accounting principles ("GAAP"). Certain of these measures are considered “non-GAAP financial measures” under the Securities and Exchange Commission ("SEC") rules. Specifically, we have referred to the following non-GAAP financial measures in this presentation: Total Segment Operating Income Adjusted EBITDA Total Adjusted Segment EBITDA Adjusted EBITDA Margin Adjusted Net Income Adjusted Earnings per Diluted Share Free Cash Flow We have included the definitions of Segment Operating Income (Loss) and Adjusted Segment EBITDA below in order to more fully define the components of certain non-GAAP financial measures in this presentation. We define Segment Operating Income (Loss) as a segment’s share of Consolidated Operating Income. We define Total Segment Operating Income, which is a non-GAAP financial measure, as the total of Segment Operating Income (Loss) for all segments, which excludes unallocated corporate expenses. We use Segment Operating Income (Loss) for the purpose of calculating Adjusted Segment EBITDA. We define Adjusted Segment EBITDA as a segment’s share of Consolidated Operating Income before depreciation, amortization of intangible assets, remeasurement of acquisition-related contingent consideration, special charges and goodwill impairment charges. We use Adjusted Segment EBITDA as a basis to internally evaluate the financial performance of our segments because we believe it reflects current core operating performance and provides an indicator of the segment’s ability to generate cash. We define Adjusted EBITDA Margin as Adjusted EBITDA as a percentage of total revenues. We define Total Adjusted Segment EBITDA, which is a non-GAAP financial measure, as the total of Adjusted Segment EBITDA for all segments, which excludes unallocated corporate expenses. We define Adjusted EBITDA, which is a non-GAAP financial measure, as consolidated net income before income tax provision, other non-operating income (expense), depreciation, amortization of intangible assets, remeasurement of acquisition-related contingent consideration, special charges, goodwill impairment charges and losses on early extinguishment of debt. We believe that the non-GAAP financial measures, which exclude the effects of remeasurement of acquisition-related contingent consideration, special charges, goodwill impairment charges and losses on early extinguishment of debt, when considered together with our GAAP financial results and GAAP measures, provide management and investors with a more complete understanding of our operating results, including underlying trends. In addition, EBITDA is a common alternative measure of operating performance used by many of our competitors. It is used by investors, financial analysts, rating agencies and others to value and compare the financial performance of companies in our industry. Therefore, we also believe that these measures, considered along with corresponding GAAP measures, provide management and investors with additional information for comparison of our operating results with the operating results of other companies. We define Adjusted Net Income and Adjusted Earnings per Diluted Share (“Adjusted EPS”), which are non-GAAP financial measures, as net income and earnings per diluted share ("EPS"), respectively, excluding the impact of remeasurement of acquisition-related contingent consideration, special charges, goodwill impairment charges, losses on early extinguishment of debt and the impact of adopting the 2017 Tax Act. We use Adjusted Net Income for the purpose of calculating Adjusted EPS. Management uses Adjusted EPS to assess total Company operating performance on a consistent basis. We believe that this non-GAAP financial measure, which excludes the effects of the remeasurement of acquisition-related contingent consideration, special charges, goodwill impairment charges, losses on early extinguishment of debt and the impact of adopting the 2017 Tax Act, when considered together with our GAAP financial results, provides management and investors with an additional understanding of our business operating results, including underlying trends. We define Free Cash Flow as net cash provided by operating activities less cash payments for purchases of property and equipment. We believe this non-GAAP financial measure, when considered together with our GAAP financial results, provides management and investors with an additional understanding of the Company’s ability to generate cash for ongoing business operations and other capital deployment. Non-GAAP financial measures are not defined in the same manner by all companies and may not be comparable with 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 our Condensed Consolidated Statements of Comprehensive Income.
