HOUSTON, Texas, USA (May 28, 2019) — NextDecade Corporation (NextDecade) (NASDAQ: NEXT) announced today that it has signed two contracts with Bechtel Oil, Gas and Chemicals (Bechtel) for the engineering, procurement, and construction (EPC) of NextDecade’s Rio Grande LNG project in Brownsville, Texas. The fully wrapped lump-sum turnkey (LSTK) EPC contracts include cost, schedule, and performance guarantees.

The EPC contracts are for the first phase of
the Rio Grande LNG project, which consists of three liquefaction trains, two
180,000 cubic meter storage tanks and two marine berths totaling $9.565
billion. Each liquefaction train is expected to have capacity up to 5.87 million
tons per annum of LNG, which would generate an EPC cost of approximately $543
per ton for the first three trains.

“We are pleased to be working with Bechtel, who is responsible for constructing about 30 percent of the world’s LNG capacity,” said Matt Schatzman, NextDecade’s President and Chief Executive Officer. “Bechtel’s extensive experience developing LNG projects on the U.S. Gulf Coast, along with our advantaged site and technology choices, including Air Products C3MR and Baker Hughes GE rotating equipment, is expected to enable NextDecade – in just the first three trains – to have the lowest cost per ton greenfield LNG project built on the U.S. Gulf Coast under a fully wrapped lump-sum turnkey EPC contract.”

“Throughout our competitive EPC process, Bechtel
has demonstrated a steadfast commitment to safety, reliability, and efficiency,”
said Ivan Van der Walt, NextDecade’s Senior Vice President of Engineering and
Construction. “Bechtel’s track record building LNG projects on the U.S. Gulf
Coast is unrivaled. Our global LNG customers, feed gas suppliers, and other
stakeholders can have the utmost confidence in the on-time and on-budget delivery
of our Rio Grande LNG project.”

The EPC contracts include full site
preparation activities, which are expected to further reduce the costs per ton of
the remaining trains to below the first phase cost of $543 per ton. In
addition, the EPC contracts provide NextDecade the ability to have Bechtel commence
construction of the first phase of Rio Grande LNG with either two or three
trains. Bechtel will perform limited notice to proceed activities from June 1,
2019 until January 1, 2020 and has agreed to accept up to $15 million in
NextDecade common stock in consideration for certain activities.

“We are honored to be selected by NextDecade
to deliver their facility using our fully integrated engineering, procurement
and direct-hire construction model,” said Alasdair Cathcart, President of Oil,
Gas and Chemicals for Bechtel. “Bechtel has a proud history of successfully
developing lump-sum turnkey LNG projects around the world, having delivered 14
large-scale LNG Trains in just the last four years.”

Pending the achievement of further commercial
milestones and receipt of final regulatory approvals, NextDecade anticipates
making a positive final investment decision on up to three trains of the Rio
Grande LNG project as early as the end of the third quarter of 2019 and commencing
operations in 2023.
