NextDecade Prices $3.5B in Senior Secured Notes for Rio Grande LNG Construction
According to Rigzone, NextDecade Corp has priced a series of senior secured notes totaling $3.5 billion to fund the under-construction Rio Grande LNG project in Brownsville, Texas, with proceeds designated to repay a portion of existing credit facility borrowings.
A Major Financing Move on an $18 Billion Project
The debt offering is structured across four tranches. The first, totaling $1 billion, carries a 5.25% interest rate and matures in 2031. A $500 million tranche follows at 5.5%, due 2034. The largest tranche, $1.25 billion, matures in 2036 at 5.75%. A final $750 million tranche due 2041 carries a 6.15% rate.
Phase 1 of Rio Grande LNG, covering liquefaction trains 1 through 3, carries a total estimated investment of $18 billion. NextDecade noted in its Q1 2026 filing that Phase 1 has refinanced more than $1.85 billion of its original $11.1 billion term loan facilities since July 2023. The new notes rank equally with existing term loan facilities and other secured debt instruments at the project level.
The project’s scope continues to grow. NextDecade greenlighted trains 4 and 5 last year, each estimated at $6.7 billion and each adding roughly 6 million metric tons per annum (MMtpa) of capacity. Total capacity under construction now stands at approximately 30 MMtpa. Trains 6 through 8 are in permitting, and the site has space for up to 10 trains. On June 12, 2026, the Department of Energy approved an export authorization increase from 27 MMtpa to approximately 30 MMtpa for free trade agreement countries. A pending court challenge over FERC’s construction approval for the first five trains remains active at a DC court, according to the Q1 2026 filing.
What It Means for Subcontractors
- Active construction financing signals ongoing work demand. With $3.5 billion in fresh debt raised and an $18 billion Phase 1 budget in motion, Rio Grande LNG remains one of the largest active LNG construction sites in the US. Subcontractors in South Texas should be tracking procurement and subcontract releases tied to trains 1 through 3.
- Trains 4 and 5 represent future contract opportunity. Each train is estimated at $6.7 billion. Field service companies, specialty contractors, and equipment suppliers should be positioning now for work packages on these trains as engineering and procurement advance.
- Project scale favors pre-qualified vendors. Projects of this size typically require extensive prequalification. Mechanical, piping, electrical, instrumentation, civil, and specialty subcontractors operating in the Brownsville and lower Rio Grande Valley area should ensure they are registered with prime contractors active on site.
- Watch the regulatory risk. The pending DC court challenge on FERC’s construction approval is a variable worth monitoring. Any disruption to the approval status of trains 1 through 5 could affect work schedules and subcontract timing.
