CAUTIONARY STATEMENT REGARDING FORWARD-LOOKING STATEMENTS This report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act and Section 21E of the Exchange Act. “Forward-looking statements” are statements related to 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 expected future business and financial performance, and often contain words such as “could,” “believe,” “would,” “anticipate,” “intend,” “estimate,” “expect,” “may,” “should,” “continue,” “plan,” “predict,” “potential,” “project,” “hypothetical,” “forecasted” and similar expressions that are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. Forward-looking statements in this report include, among other things, statements about the anticipated timing of closing the Acquisitions. Actual results and future events could differ materially from those anticipated in such statements, and such forward-looking statements may not prove to be accurate. These forward-looking statements involve certain risks and uncertainties, including, but not limited to, the following risks and uncertainties related to the Acquisitions: the ability of the parties to consummate the Acquisitions in the anticipated timeframe or at all; risks related to the satisfaction or waiver of the conditions to closing the Acquisitions in the anticipated timeframe or at all; risks related to obtaining the requisite regulatory approvals; disruption from the Acquisitions making it more difficult to maintain business and operational relationships; significant transaction costs associated with the Acquisitions; the risk of litigation and/or regulatory actions related to the Acquisitions; other business effects, including the effects of industry, market, economic, political or regulatory conditions; and the other factors which could cause actual results to differ materially from those anticipated or implied in the forward-looking statements. Matador may not succeed in addressing these and other risks. For further discussions of risks and uncertainties, you should refer to Matador’s filings with the SEC, including the “Risk Factors” section of Matador’s most recent Annual Report on Form 10-K and any subsequent Quarterly Reports on Form 10-Q. Matador undertakes no obligation to update these forward-looking statements to reflect events or circumstances occurring after the date of this report, except as required by law, including the securities laws of the United States and the rules and regulations of the SEC. Investors are cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date of this report. All forward-looking statements are qualified in their entirety by this cautionary statement. Item 9.01 Financial Statements and Exhibits.
