• RGLNG’s EPC process was previously a sole-sourced engagement with McDermott

• Planned to sign lump-sum turnkey (LSTK) EPC contract in 2Q 2018

• NextDecade owns the front-end engineering and design (FEED) work completed in late 2017

• Competitive EPC process launched in August 2018 based on rigorous evaluation criteria

• Three eligible EPC contractors received invitations to bid: Bechtel, Fluor, and McDermott

• McDermott invitation stipulates it shall secure joint venture partner to remain an eligible bidder

• Process underway with interim deliverables due from contractors on a rolling basis

• Invitations to bid require FEED endorsement by year-end 2018 and LSTK EPC bids in 2Q 2019

• Execution of final LSTK EPC contract expected in 3Q 2019 prior to RGLNG final investment decision (FID)

• Deliberate approach to achieve a competitively priced, fully wrapped LSTK EPC contract

• Ensure contractor has technical and financial strength to deliver a project of RGLNG’s size and scope

• Safe, on-time, on-budget delivery of RGLNG is critically important to NextDecade and its stakeholders

• On October 12, 2018, the Federal Energy Regulatory Commission (FERC) issued its draft Environmental Impact Statement (EIS) on the Rio Grande LNG project and the associated Rio Bravo Pipeline

• According to the Notice of Schedule published in August 2018, FERC will issue a final EIS on April 26, 2019

• Recent policy changes to bring safe and expeditious review of – and decisions on – U.S. LNG projects

• FERC’s streamlining of the review process for LNG projects confirms that no single project will have a regulatory advantage, and that regulatory certainty will “help minimize undue administrative burdens”1

Accessing the Permian: Waha to Agua Dulce

• New planned transport from Waha to the Agua Dulce and Katy markets are preferred paths for Permian Basin gas

• RGLNG is the largest planned LNG export facility in the State of Texas, and benefits from its proximity to abundant associated gas in the Permian Basin

• Proposed LNG projects in East Texas and Louisiana face higher transportation costs to source Permian gas

• The Permian Basin offers the deepest inventory of economic resource in the United States

• In the past few years, the Permian Basin has garnered significant attention and capital

• Permian Basin economics are driven by the production of oil – not by gas

• Texas and New Mexico prohibit long-term flaring of natural gas, so Permian producers must find a market for associated gas to enable oil production

• The Permian Basin is estimated to hold nearly 500 Tcf – or more than 50 years –of natural gas at breakevens below $0*

• This represents a major opportunity for LNG buyers transacting with second wave U.S. LNG projects in Texas
