Funded utility growth faces near term execution delays

01 Running thesis

Execution risks reappear

Sempra hit speed bumps in the middle of 2026. While ECA LNG Phase 1 successfully exported its first cargo, the facility required a shutdown after damage was found in its refrigerant compressors. Management pushed expected substantial completion to the fourth quarter of 2026. This delay brings customer termination rights back into view if the fix takes longer than expected.

The funding plan also saw a minor delay. The sale of a 45% stake in SI Partners for $9.99B is now expected to close near the end of the third quarter of 2026. The record $65B five-year capital plan still relies on those proceeds so it needs no new common equity.

The bull case relies on steadier growth from California and Texas utilities. Oncor is being helped by data center load growth and the new Unified Tracker Mechanism. Oncor also benefits from a favorable April 2026 rate order with a 9.75% authorized return on equity.

The bear case gains ground from the ECA LNG compressor issue and new regulatory concerns. Other utilities claimed large amounts from the California Wildfire Fund related to the LA Fires. Sempra warns those claims could materially reduce or exhaust the fund, which removes a key layer of safety for SDG&E.

Aug 2026▼Q2 2026 revealed execution setbacks. ECA LNG Phase 1 suffered compressor damage, delaying substantial completion to Q4 2026. The SI Partners sale timeline moved to late Q3 2026, and wildfire fund depletion risks rose.
May 2026▲Q1 2026 strengthened the thesis. ECA LNG Phase 1 is receiving feedgas, management expects first LNG in June 2026, and the $65B five-year capital plan was reaffirmed with no new common equity needed.
May 2026▲The Q1 2026 Form 10-Q added support for the Texas growth case. Oncor received a favorable April 2026 rate order with a 9.75% authorized return on equity, while the SI Partners sale was still expected to close in Q2 or Q3 2026.
Feb 2026▲The 2025 Form 10-K confirmed Sempra's shift toward a core regulated U.S. utility. The planned $9.99B SI Partners sale reduced financing risk, while tariffs became a clearer cost risk for LNG construction.
Nov 2025▲Sempra reached final investment decision and started construction on Port Arthur LNG Phase 2. The SI Partners sale agreement also clarified the capital recycling plan, but it reduced Sempra's future control of the infrastructure business.
Aug 2025→ECA LNG Phase 1 timing shifted toward summer 2026, while Port Arthur construction continued after the fatal site incident. The core debate stayed focused on LNG execution.
May 2025▼A fatal construction incident at Port Arthur LNG Phase 1 raised execution and legal risk. New tariff disclosures and Mexico energy policy changes also made the bear case more concrete.
Feb 2025→The first thesis framed Sempra as a mix of stable regulated utilities and higher-risk LNG growth. The key balance was predictable utility returns against wildfire, regulatory, and LNG project risks.
02 Business model

Monopoly wires and contracted gas exports

Sempra makes most of its money by owning regulated energy networks. In California, SDG&E and SoCalGas deliver electricity and natural gas. In Texas, Sempra owns most of Oncor, the largest power transmission and distribution system in the state.

Regulated utilities work differently from normal businesses. They spend money on poles, wires, pipes, and safety projects. Regulators then allow them to earn a set return on that capital if the spending is approved. That can make earnings steadier, but it also means regulators can cut or delay recovery.

Sempra Infrastructure is the higher risk growth arm. It builds LNG export plants, pipelines, storage, and renewable power assets. LNG plants usually sell capacity under long-term contracts, which can make cash flow more predictable once a plant is built. The hard part is getting huge projects finished on time and on budget.

After the SI Partners sale closes, Sempra is expected to own a 25% non-controlling stake in that business. That should reduce funding stress, but it also means Sempra will have less control over a major growth platform.

03 Product portfolio

What Sempra actually owns

Steady

SDG&E electric and gas utility

SDG&E serves electric customers in San Diego and southern Orange counties and gas customers in San Diego County. It is regulated, so allowed returns matter more than market prices.

Cash cow

SoCalGas natural gas utility

SoCalGas provides natural gas distribution, transmission, and storage service to much of Southern California. It faces long-term policy pressure in the state.

Growth engine

Oncor Texas power grid

Oncor serves over 4 million homes and businesses and is seeing faster growth from large power users, including data centers. The new Unified Tracker Mechanism helps support grid investment recovery.

Steady

Sharyland Utilities

Sempra owns a 50% stake in Sharyland, a regulated Texas electric transmission utility. It is smaller than Oncor but fits the same regulated grid theme.

Growth engine

ECA LNG Phase 1

ECA LNG Phase 1 exported its first cargo in July 2026. Compressor damage has delayed expected substantial completion to the fourth quarter of 2026.

Option

Port Arthur LNG

Port Arthur LNG is Sempra Infrastructure's big long-term LNG build in Texas. Phase 1 is expected to start commercial operations near the end of 2027 and in 2028.

Steady

Pipelines and Mexico renewables

Sempra Infrastructure also owns natural gas pipelines, storage, and renewable generation assets, including assets in Mexico.

05 Risk factors

What can still break

ECA LNG compressor remediation

High impact · Medium odds

ECA LNG Phase 1 suffered compressor damage after exporting its first cargo. Substantial completion is delayed to the fourth quarter of 2026. If the delay extends further, customers might exercise their termination rights.

We watchWatch root cause investigation updates, remediation costs, and any customer termination notices.

California Wildfire Fund depletion

High impact · Medium odds

Other utilities recently filed claims expected to exceed $2 billion for LA Fires. Sempra warns this could materially reduce or exhaust the Wildfire Fund, leaving SDG&E with less protection against future claims.

We watchWatch California wildfire claims, fund balances, and legislative responses.

Port Arthur LNG build risk

High impact · Medium odds

Port Arthur LNG is a large construction project with years left before full cash flow. Management says Phase 1 remains on time, with Train 1 near the end of 2027 and Train 2 in 2028. Construction delays would hit future cash flow assumptions.

We watchWatch Port Arthur Phase 1 schedule updates and Bechtel construction progress.

SI Partners sale delay

High impact · Low odds

The $9.99B sale of a 45% stake in SI Partners is central to the no new equity funding claim. Sempra expects closing near the end of the third quarter of 2026. A delay or worse terms would bring back financing concerns.

We watchWatch for closing of the SI Partners sale and details on use of proceeds.

Tariffs raise LNG costs

Medium impact · Medium odds

Sempra warns that new and higher U.S. tariffs on imported materials could raise costs across LNG projects. That matters most for Port Arthur, where even small percentage overruns can mean large dollar changes.

We watchWatch management's quantified tariff impact on Port Arthur Phase 1 and Phase 2 capital budgets.

Texas load boom disappoints

Medium impact · Medium odds

Oncor's growth case depends on connecting large new loads, especially data centers. If ERCOT approvals, transmission projects, or customer commitments slow, the earnings lift could arrive later than hoped.

We watchWatch ERCOT approvals and Oncor disclosures on the timeline to connect large load requests.
06 Quick answers

In one breath

Is Sempra mainly a utility or an LNG company?

Sempra is mainly a regulated utility holding company, with major gas and electric networks in California and Texas. It also owns LNG and pipeline assets through Sempra Infrastructure, but its planned SI Partners sale makes the company look more utility-heavy.

Why does the SI Partners sale matter?

Sempra agreed to sell a 45% stake in SI Partners for $9.99B. Management says that deal helps fund the $65B five-year capital plan without issuing new common equity.

What is the biggest near-term catalyst for Sempra?

ECA LNG Phase 1 is a key catalyst. It exported its first cargo but compressor damage delayed substantial completion to the fourth quarter of 2026.

What is Oncor's role in the Sempra story?

Oncor is Sempra's Texas grid business and a key growth engine. Data centers and other large power users are driving demand, while the Unified Tracker Mechanism and a 9.75% authorized return on equity improve the regulatory setup.
