Learn moreSempra (NYSE:SRE) added a long-term customer commitment on September 14, when its infrastructure subsidiary announced a 20-year sales and purchase agreement with Petróleo Brasileiro S.A. - Petrobras (NYSE:PBR). The agreement covers approximately 0.8 million tonnes annually of liquefied natural gas, or LNG.
Supply will come from the subsidiary's contracted liquefaction capacity at Port Arthur LNG Phase 2 in Texas. The project is under construction, with trains 3 and 4 expected to begin commercial operations in 2030 and 2031, respectively. The agreement improves visibility into future sales, while the earnings contribution depends on delivery and contract economics.
Bull Case
Petróleo Brasileiro S.A. - Petrobras (NYSE:PBR) becomes the infrastructure subsidiary's first South American LNG customer. That broadens the geographic base of buyers and establishes a commercial relationship extending over two decades.
For Sempra (NYSE:SRE), the practical benefit is an external buyer for part of the subsidiary's contracted capacity. Securing that relationship before startup could reduce the need to find buyers for the covered volumes as production approaches, while supporting longer-term supply planning.
The annual commitment equals approximately 6.2% of Phase 2's planned 13-million-tonne annual capacity. This provides a measure of scale, although it does not establish the percentage of capacity still available for sale.
The project also has an established development framework. Phase 2 reached a positive final investment decision in September 2025, and Bechtel Energy Inc. received full notice to proceed with construction. Using the same contractor across both phases could support continuity in execution. The new agreement builds on that existing investment and construction program.
Sempra (NYSE:SRE) has agreed to sell a 45% interest in Sempra Infrastructure Partners, retaining 25% after closing. The transaction remained pending in the latest disclosures, with closing expected in the third quarter of 2026. Its participation in future LNG earnings would reflect that smaller ownership stake.
Bear Case
The announcement does not disclose the pricing formula, expected contract margin, or detailed payment and termination provisions. Those terms determine how much commodity-price exposure remains and how reliably contracted volumes translate into earnings. A 20-year duration alone does not establish fixed revenue or protected profitability.
Construction remains a substantial financial commitment. At the September 2025 investment decision, estimated project-level incremental capital expenditure was approximately $12 billion, plus $2 billion for shared facilities.
