Corporate Updates

NextDecade is a development company focused on delivering liquefied
natural gas (LNG) from projects in the State of Texas to partners and
customers around the world. Among its portfolio of projects is Rio
Grande LNG, a 27 mtpa project on a 1,000-acre site in the Port of
Brownsville. NextDecade is a leader among the second wave of U.S.
project sponsors. Rio Grande LNG represents a low-cost, reliable LNG
solution for customers around the world. Significant competitive
advantages are listed below.

• NextDecade is using proven liquefaction technology from Air Products
  (C3MR) to develop one of the lowest cost U.S. LNG facilities. The
  Company’s engineering, procurement, and construction (EPC) cost
  estimate is $478-502 per ton; NextDecade is targeting further
  improvements to reduce EPC costs to as low as $450 per ton, working
  closely with Chicago Bridge & Iron (EPC contractor) and BakerHughes, a
  GE Company (partner for processing equipment and a NextDecade
  shareholder). NextDecade is in the process of finalizing detailed
  negotiations for its lump-sum turnkey (LSTK) EPC contract with CB&I.
• Rio Grande LNG is located in close proximity to low-cost gas reserves
  in the Permian Basin and Eagle Ford Shale. Multiple midstream
  companies have already announced significant pipeline projects from
  Waha to Agua Dulce, where NextDecade’s twin 42-inch pipelines (Rio
  Bravo) will originate. NextDecade’s Rio Grande LNG project can be
  viewed as a pipeline to the world for U.S. E&P companies who require
  an outlet for associated gas, in particular, from the Permian Basin.
• NextDecade can take a final investment decision (FID) on the Rio
  Grande LNG project for as few as two trains (approximately 9 mtpa).
  The project is scalable up to 6 trains (27 mtpa). NextDecade intends
  to develop the full 6-train plant at Rio Grande LNG, but does not need
  to develop the full-scale facility in order to offer customers
  significant cost advantages, environmental benefits, and reliable LNG
  supply.
• NextDecade is advancing through the Federal Energy Regulatory
  Commission (FERC) process. NextDecade expects to receive a notice of
  schedule for its Rio Grande LNG project in the near future, and to
  receive a final authorization in the second half of 2018.
• NextDecade has a seasoned leadership team with marketing and
  development experience to execute its projects, and strong
  partnerships in the institutional asset management community.
