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 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: progress and timing in the development of and final investment decision ("FID") in the construction and operation of a LNG terminal at the Port of Brownsville in southern Texas (the "Terminal"); the successful completion of the Terminal by third-party contractors and a pipeline to supply gas to the Terminal being developed by a third-party (the "Pipeline"); the Company's ability to develop its CCS business line through deployment and operation of CCS processes that capture and store carbon dioxide ("CO2") emissions at third-party facilities and at the Terminal (the "CCS project"); the accuracy of estimated costs for the Terminal, the CCS project, and implementation of the CCS processes at third-party facilities; operational characteristics of the Terminal, the CCS project, and the CCS processes, when completed or implemented, including amounts of liquefaction capacities or amount of CO2 captured and stored; the development risks, operational hazards, and regulatory approvals applicable to the Company's LNG and CCS development, construction, and operations activities; the global demand for and price of LNG; the 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 that reasonably price emission costs; global development and maturation of emissions reduction credit/offset markets; adverse changes to existing and planned CCS tax incentive regimes; global pandemics, including the 2019 novel coronavirus pandemic, and their impact on the Company's business and operating results, including any disruptions in the Company's operations or development activities and the health and safety of the Company's employees, and on the Company's customers, the global economy, the demand for LNG, and number and scale of implemented CCS projects; risks related to doing business in and having counterparties in foreign countries; technological innovation which may lessen the Company's anticipated competitive advantages; the Company's ability to secure additional corporate and/or project debt and equity financing in the future at levels required to execute its business plans; the Company's ability to maintain the listing of its securities on a securities exchange or quotation medium; changes adversely affecting the business in which the Company is engaged; management of growth; general economic conditions; the Company's ability to generate cash; compliance with environmental laws and regulations; and the result of future financing efforts and applications for customary tax incentives.
