Hanwha Aerospace, a 10% owner of NextDecade Corporation, purchased 1.65 million shares in open-market transactions on 11 and 12 December 2025, worth $9.4 million. The acquisition is Hanwha's largest single transaction in the past year and brings its direct holdings to 26.4 million shares, valued at approximately $144.3 million. The purchase appears strategically motivated by Hanwha's August memorandum of understanding with Hanwha Energy and Korea Southern Power to develop an integrated LNG value chain. NextDecade, which develops LNG export facilities and carbon capture projects in Texas, currently generates no revenue and recorded $180 million in operating expenses over the first nine months of 2025. The company expects to begin LNG sales from its Rio Grande facility in the early 2030s.

John Wood Group PLC has secured a major ten-year agreement with NextDecade to provide maintenance services at the Rio Grande LNG facility, a large-scale natural gas liquefaction and export project currently under development near Brownsville, Texas. Under the contract, Wood will deliver a full range of maintenance services to help ensure safe, reliable, and efficient operations across the approximately 1,000-acre site. NextDecade anticipates the facility will play a key role in supplying secure and affordable energy through the responsible development and operation of natural gas liquefaction capacity. Wood is already engaged in the execution of mechanical integrity programs for the facility and is providing advisory support on operational readiness. Steve Nicol, Executive President of Operations at Wood, said: "This contract strengthens Wood's presence in the US LNG market and underscores its commitment to supporting the growth of US LNG exports. Drawing on more than 50 years of experience maintaining facilities along the US Gulf Coast, PetropipeFZE will work closely with NextDecade to help deliver safe and dependable LNG production in Texas. "We also share NextDecade's commitment to the Rio Grande Valley communities. As part of this project, we plan to establish a new local office and partner with regional colleges to attract and develop talent through our apprenticeship programs." The contract is expected to create more than 100 new jobs, with an emphasis on local hiring and continued investment in workforce development across the United States.
