Disclaimer Statement This Presentation contains certain statements that are, or may be deemed to be, "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements other than statements of historical fact contained in this presentation, including statements regarding the future results of operations and financial position of NextDecade Corporation and its subsidiaries (collectively, the "Company"), its strategy and plans, its expectations for future operations and transactions, environmental, regulatory and legislative matters and future demand and supply affecting liquefied natural gas ("LNG") and general energy markets, are forward-looking statements. The words "anticipate," "assume," "budget," "contemplate," "estimate," "expect," "forecast," "project," "potential," "plan," "initial," "intend," "believe," "may," "might," "will," "would," "could," "should," "can have," "likely," "continue," "design" and other words and terms of similar expressions, are intended to identify forward-looking statements. The Company has based these forward-looking statements largely on its current expectations and projections about future events and trends that it believes may affect its financial condition, results of operations, strategy, short-term and long-term business operations, and objectives and financial needs. Although the Company believes that the expectations reflected in its forward-looking statements are reasonable, actual results could differ from those expressed in its forward-looking statements. The Company's future financial position and results of operations as well as any forward-looking statements are subject to change and inherent risks and uncertainties. You should consider the Company's forward-looking statements in light of a number of factors that may cause actual results to vary from its forward-looking statements regarding general business activities or its LNG and carbon capture and storage ("CCS") business lines including, but not limited to: the Company's progress in the development of its LNG liquefaction and export projects and CCS projects and the timing of that progress; the timing and cost of the development, construction and operation of the first three liquefaction trains and related common facilities ("Phase 1") of the multi-plant integrated natural gas and liquefaction and LNG export terminal facility to be located at the Port of Brownsville in southern Texas (the "Terminal"); the availability and frequency of cash distributions available to the Company from its joint venture owning Phase 1 of the Terminal; the timing and cost of the development of Trains 4 and 5 at the Terminal; the ability to generate sufficient cash flow to satisfy significant debt service obligations of Rio Grande LNG, LLC ("RGLNG"), the entity owning Phase 1 of the Terminal, or to refinance such obligations ahead of their maturity; restrictions imposed by Rio Grande's debt agreements that limit flexibility in operating its business; increases in interest rates governing RGLNG's variable rate indebtedness increasing the cost of servicing RGLNG's substantial indebtedness; reliance on third-party contractors to successfully complete the Terminal, the pipeline to supply gas to the Terminal and any CCS projects; ability to develop NEXT Carbon Solutions' business though implementation of CCS projects; ability to comply with the terms of the debt and commercial agreements related to the Terminal; ability to secure additional debt and equity financing in the future on commercially acceptable terms; accuracy of estimated costs for the Terminal and CCS projects; ability to achieve operational characteristics of the Terminal and CCS projects, when completed, including liquefaction capacities and amount of CO2 captured and stored, and any differences in such operational characteristics from expectations; development risks, operational hazards and regulatory approvals applicable to the Company's development, construction and operation activities and those of its third- party contractors and counterparties; technological innovation which may lessen the Company's anticipated competitive advantage or demand for its offerings; global demand for and price of LNG; availability of LNG vessels worldwide; changes in legislation and regulations relating to the LNG and CCS industries, including environmental laws and regulations that impose significant compliance costs and liabilities; scope of implementation of carbon pricing regimes aimed at reducing greenhouse gas emissions; global development and maturation of emissions reduction credit markets; adverse changes to existing or proposed carbon tax incentive regimes; global pandemics, including the 2019 novel coronavirus pandemic, the Russia-Ukraine conflict, other sources of volatility in the energy markets and their impact on the Company's business and operating results, including any disruptions in its operations or development of the Terminal and the health and safety of its employees, and on its customers, the global economy and the demand for LNG; risks related to doing business in and having counterparties in foreign countries; the Company's ability to maintain the listing of our securities on the Nasdaq Capital Market or another securities exchange or quotation medium; changes adversely affecting the businesses in which the Company is engaged; management of growth; general economic conditions; ability to generate cash; and the result of future financing efforts and applications for customary tax incentives. Additional factors that you should consider are set forth in detail in the "Risk Factors" section of the Company's most recent Annual Report on Form 10-K as well as other filings the Company has made and will make with the Securities and Exchange Commission which, after their filing, can be found on the Company's website, www.next-decade.com. Financial forecasts, estimates, or other forward-looking financial information included in this presentation is meant for illustrative purposes only and does not purport to show estimates of actual future financial performance over any particular period. The information on such slides has not been reviewed by the Company's independent auditor and the Company's independent auditor expresses no opinion with respect to such information. The information on such slides assumes the completion of certain commercial, financing, and other transactions. Such transactions may not be completed on the terms we assume or at all. Actual commodity prices and the terms of commercial and financing arrangements may vary materially from those assumed for the purposes of the illustrative financial performance information. Should one or more of the foregoing risks or uncertainties materialize in a way that negatively impacts the Company, or should its underlying assumptions prove incorrect, its actual results may vary materially from those anticipated in its forward-looking statements and, its business, financial condition and results of operations could be materially and adversely affected. You should not rely upon forward-looking statements as predictions of future events. In addition, neither the Company nor any other person assumes responsibility for the accuracy and completeness of any of these forward- looking statements. The Company cautions readers that the information contained in this presentation is only current as of the date of this presentation and, therefore, except as required by applicable law, the Company does not undertake any obligation to publicly correct or update any forward-looking statement. This Presentation contains forecasts of Distributable Cash Flow, which is a non-GAAP measure. Due to the high variability and difficulty in making accurate forecasts and projections of Distributable Cash Flow, together with some of the excluded information not being ascertainable or accessible, the Company is unable to quantify certain amounts that would be required to be included in the most directly comparable GAAP financial measure without unreasonable effort. Consequently, no disclosure of estimated comparable GAAP measure is included, and no reconciliation of the forward-looking non- GAAP financial measure is included. This presentation is not an offer to purchase or sell, or a solicitation of an offer to purchase or sell, any securities.
