Stonepeak Raises $2.5 Billion in Private Bonds Tied to LNG Plant

In a clear signal of strong institutional appetite for U.S. Gulf Coast LNG infrastructure, alternative investment firm Stonepeak has raised approximately $2.5 billion in private bonds to refinance debt linked to its investment in the Louisiana LNG export terminal project.

The bonds were issued by Stonepeak Wallaby I Acquiror LP, the dedicated holding company for Stonepeak’s stake in the project. The transaction was arranged by Mizuho Financial Group and RBC as a true private placement.

Background on Stonepeak’s Louisiana LNG Investment

Stonepeak acquired a 40% interest in Louisiana LNG Infrastructure LLC from Woodside Energy Group Ltd (ASX: WDS, NYSE: WDS) in June 2025, following the project’s Final Investment Decision (FID) in April 2025.

As part of the deal, Stonepeak committed to contributing $5.7 billion toward the foundation phase capital expenditures on an accelerated basis (75% of capex in both 2025 and 2026), in addition to its equity stake. Woodside retains the remaining 60% and continues to operate the facility.

The project is located in Calcasieu Parish, Louisiana (near Lake Charles), in the heart of the U.S. Gulf Coast LNG corridor. The foundation development includes three liquefaction trains with a combined capacity of 16.5 million tonnes per annum (Mtpa). The site has a total permitted capacity of 27.6 Mtpa across five trains. Bechtel serves as the engineering, procurement, and construction (EPC) contractor.

Financing History and the Latest Refinancing

Stonepeak closed a $6.04 billion acquisition financing package in mid-2025 to fund its entry into the project.

In October 2025, the company executed a $2 billion private placement (under Section 4(a)(2)) partial refinancing of the original bank facility, with noteholders advised by Milbank and participation from investors including Apollo and Apterra Infrastructure Capital.

The new $2.5 billion issuance in June 2026 represents a further step in optimizing the capital structure at the holdco level by replacing or extending portions of the earlier debt with longer-term private bonds.Project Status (as of mid-2026)

Construction is underway following the groundbreaking in September 2025. As of early 2026 reporting, the foundation phase had reached approximately 22% completion, with Train 1 slightly ahead of schedule. First LNG production is targeted for 2029, with full foundation capacity online around 2031. The U.S. Department of Energy has granted extensions for export authorizations.

Commercialization (offtake) is ongoing. At the time of FID, only a modest portion of capacity was under long-term contract, which is lower than typical for sanctioned LNG projects; Woodside and partners continue marketing efforts.

What This Means for Potential Investors

For institutional bond buyers / private credit investors:
This transaction underscores the depth and liquidity of private markets for high-quality U.S. energy infrastructure. Private placements like this typically target sophisticated investors (pension funds, insurance companies, endowments, sovereign wealth funds, and specialized credit funds) seeking attractive yields backed by long-duration, tangible assets. Once operational, LNG export terminals generate relatively stable, contracted cash flows from global energy demand. The refinancing signals progress on construction milestones and lender/investor confidence in the sponsors (Stonepeak’s infrastructure expertise + Woodside’s operating track record).Key considerations and risks:

• Construction and timeline risk remain material until the first cargo (target 2029).
• Offtake coverage is still developing compared to many peers.
• Broader sector factors include U.S. natural gas supply dynamics, global LNG demand (especially in Europe and Asia), regulatory/tariff developments, and environmental considerations.
• Private bonds offer potentially higher yields than public markets but come with limited liquidity and disclosure.

For Stonepeak and its fund investors:
The ability to refinance bank debt into longer-term private bonds at the project holdco level is positive. It can lower the overall cost of capital, extend debt maturity, improve liquidity, and support better risk-adjusted returns on the equity investment. It demonstrates Stonepeak’s strong access to capital markets for its portfolio companies.

Broader market implications:
The deal reflects continued institutional capital flowing into U.S. LNG despite policy volatility, tariffs, and energy transition debates. It highlights how private credit is playing an increasingly important role in bridging the gap between traditional bank construction financing and long-term project debt. Similar activity has been seen at other Gulf Coast LNG facilities.

Overall, the transaction reinforces Louisiana LNG as a major sanctioned project moving forward with credible sponsorship and access to deep pockets of private capital.
