Certain statements made in this presentation may constitute "forward-looking statements" within the meaning of the safe harbor provisions of the United States Private Securities Litigation Reform Act of 1995 — that is, statements related to the future, not past, events. Forward-looking statements are based on current expectations and include any statement that does not directly relate to a current or historical fact. In this context, forward-looking statements often address our expected future business and financial performance, and often contain words such as "anticipate," "believe," "intend," "expect," "plan" or other similar words. Forward-looking statements in this presentation include, without limitation, statements regarding projected revenue, Adjusted EBITDA and Unlevered Free Cash Flow (UFCF) for RigNet. These forward-looking statements involve certain risks and uncertainties that ultimately may not prove to be accurate. Actual results and future events could differ materially from those anticipated in such statements. Factors that could cause actual results to differ materially from those contemplated in our forward-looking statements include, among others: adverse changes in economic conditions in the markets we operate; the extent, timing and overall effects of competition in our industry; the impact of new, emerging or competing technologies; material changes in the communications industry that could adversely affect vendor relationships with equipment and network suppliers and customer relationships with wholesale customers; unfavorable results of litigation or intellectual property infringement claims asserted against us; unanticipated increases or other changes in our future cash requirements; the effects of federal and state legislation, and rules and regulations governing the communications industry; the impact of equipment failure, natural disasters or terrorist acts; and those additional factors set forth under the caption “Risk Factors” and other factors described in our filings with the SEC, including under the section “Management’s Discussion and Analysis of Financial Condition and Results of Operations” in our Form 10-K for the fiscal period December 31, 2016, which is incorporated by reference herein. RigNet undertakes no obligation and does not intend to update these forward-looking statements to reflect events or circumstances occurring after this press release. You are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this press release. All forward-looking statements are qualified in their entirety by this cautionary statement. In addition to U.S. GAAP financials, this presentation includes certain non-GAAP financial measures. These non-GAAP measures are in addition to, not a substitute for or superior to, measures of financial performance prepared in accordance with GAAP. Definitions of these non-GAAP measures and reconciliations between certain GAAP and non-GAAP measures are included in the appendix to this presentation. FORWARD-LOOKING STATEMENTS ALWAYS CONNECTED
