Cautionary Statement Cautionary Statement Regarding Forward-Looking Statements This presentation contains “forward-looking statements” for purposes of the federal securities laws. All statements, other than statements of historical fact included in this presentation, regarding the proposed transaction with EnVen, including our ability to satisfy the conditions to closing and the expected timing and benefits of the transaction, our strategy, future operations, the impact of regulatory changes, financial position, estimated capital expenditures, production, revenues and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this presentation, the words “could,” “believe,” “anticipate,” “intend,” “estimate,” “expect,” “project” and similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on our current expectations and assumptions about future events and are based on currently available information as to the outcome and timing of future events. We caution you that these forward-looking statements are subject to numerous risks and uncertainties, most of which are difficult to predict and many of which are beyond our control. These risks include, but are not limited to, the success of our carbon capture and sequestration projects; commodity price volatility due to the continued impact of the coronavirus disease 2019 (“COVID-19), including any new strains or variants, and governmental measures related thereto on global demand for oil and natural gas and on the operations of our business; the lack of a resolution to the war in Ukraine and its impact on certain commodity markets; the ability or willingness of the Organization of Petroleum Exporting Countries (“OPEC”) and non-OPEC countries, such as Saudi Arabia and Russia, to set and maintain oil production levels and the impact of any such actions, lack of transportation and storage capacity as a result of oversupply, government regulations and actions or other factors, sustained inflation and the impact of central bank policy responses thereto, lack of availability of drilling and production equipment and services, environmental risks, drilling and other operating risks, regulatory changes, the uncertainty inherent in estimating reserves and in projecting future rates of production, cash flow and access to capital, the timing of development expenditures, the possibility that the anticipated benefits of recent or proposed acquisitions (including the proposed transaction discussed herein) are not realized when expected or at all, including as a result of the impact of, or problems arising from, the integration of such acquisitions, our ability to satisfy the conditions to closing to the proposed EnVen transaction as well as other factors discussed under the heading “Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2021, Quarterly Report on Form 10-Q for the period ended June 30, 2022 and other filings with the SEC. Should one or more of these risks or uncertainties occur, or should underlying assumptions prove incorrect, our actual results and plans could differ materially from those expressed in any forward-looking statements. All forward-looking statements, expressed or implied, are expressly qualified in their entirety by this cautionary statement. This cautionary statement should also be considered in connection with any subsequent written or oral forward-looking statements that we or persons acting on our behalf may issue. All forward-looking statements speak only as of the date hereof. Except as otherwise required by applicable law, we disclaim any duty to update any forward-looking statements, to reflect events or circumstances after the date of this presentation. Reserve Information Reserve engineering is a process of estimating underground accumulations of oil, natural gas and NGLs. The accuracy of any reserve estimate depends on the quality of available data, the interpretation of such data and price and cost assumptions made by reserve engineers. In addition, the results of drilling, testing and production activities may justify revisions upward or downward of estimates that were made previously. If significant, such revisions would change the schedule of any further production and development drilling. Accordingly, reserve estimates may differ significantly from the quantities of oil, natural gas and NGLs that are ultimately recovered. Investors are urged to consider closely the disclosures and risk factors in the reports we file with the SEC. Estimates for our future production volumes are based on assumptions of capital expenditure levels and the assumption that market demand and prices for oil and gas will continue at levels that allow for economic production of these products. The production, transportation and marketing of oil and gas are subject to disruption due to transportation and processing availability, mechanical failure, human error, hurricanes, global political and macroeconomic events and numerous other factors. Our estimates are based on certain other assumptions, such as well performance, which may vary significantly from those assumed. Therefore, we can give no assurance that our future production volumes will be as estimated. Use of Non-GAAP Financial Measures This presentation includes the use of certain measures that have not been calculated in accordance with U.S. generally acceptable accounting principles (GAAP), including EBITDA, Adjusted EBITDA, Net Debt, Free Cash Flow and Leverage. Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for analysis of our results as reported under GAAP. Use of Projections This presentation contains projections, including production volumes, capital expenditures, Adjusted EBITDA, Free Cash Flow and cost-savings via synergies. Our independent auditors have not audited, reviewed, compiled, or performed any procedures with respect to the projections for the purpose of their inclusion in this presentation, and accordingly, have not expressed an opinion or provided any other form of assurance with respect thereto for the purpose of this presentation. These projections are for illustrative purposes only and should not be relied upon as being indicative of future results. The assumptions and estimates underlying the projected information are inherently uncertain and are subject to a wide variety of significant business, economic and competitive risks and uncertainties that could cause actual results to differ materially from those contained in the projected information. Even if our assumptions and estimates are correct, projections are inherently uncertain due to a number of factors outside our control. Accordingly, there can be no assurance that the projected results are indicative of our future performance after completion of the transaction or that actual results will not differ materially from those presented in the projected information. Inclusion of the projected information in this presentation should not be regarded as a representation by any person that the results contained in the projected information will be achieved. Industry and Market Data; Trademarks and Trade Names This presentation has been prepared by us and includes market data and other statistical information from sources we believe to be reliable, including independent industry publications, governmental publications or other published independent sources. Some data is also based on our good faith estimates, which are derived from our review of internal sources as well as the independent sources described above. Although we believe these sources are reliable, we have not independently verified the information and cannot guarantee its accuracy and completeness. We own or have rights to various trademarks, service marks and trade names that we use in connection with the operation of our businesses. This presentation also contains trademarks, service marks and trade names of third parties, which are the property of their respective owners.
