NextDecade's Rio Grande LNG Project 67.8% Complete

Developments: Construction and Commissioning - Under the engineering, procurement, and construction ("EPC") contracts with Bechtel Energy, as of March 2026: The overall project completion percentage for Trains 1 and 2 and the common facilities at the Rio Grande LNG Facility was 67.8%. Early electrical commissioning of Train 1 continues, and we expect first gas into the Rio Grande LNG Facility in the second half of 2026 and first LNG production from Train 1 in the first half of 2027. Strategic and Commercial - In early 2026, we began the marketing of early cargoes that we expect to produce in 2027 and 2028 prior to the commencement of our long-term LNG Sale and Purchase Agreements. In February 2026, we entered into LNG sales agreements for the sale of over 175 TBtu of LNG on a free-on-board basis, with fixed liquefaction fees that are expected to achieve a cargo margin, calculated as the FOB LNG sales price less our expected costs of natural gas feedstock and fuel, of over $3.00 per MMBtu. This volume represents 33% of our expected portfolio volumes from 2027 through early 2029. NextDecade is constructing and developing the Rio Grande LNG Facility on the north shore of the Brownsville Ship Channel in south Texas. Construction commenced on Phase 1 at the Rio Grande LNG Facility in July 2023, on Train 4 in September 2025, and on Train 5 in October 2025, in each case following a positive final investment decision and the closing of project financing by the Company's subsidiaries. Construction will be completed by Bechtel under fully wrapped, lump-sum turnkey EPC contracts, and the liquefaction trains will utilize Honeywell AP-C3MR liquefaction technology, which is a predominant liquefaction technology utilized globally.
