Sempra (SRE)

Overview

Sempra is a San Diego, California-based energy infrastructure holding company and one of the largest regulated utility groups in North America. It operates in the utilities sector, controlling electric and natural gas distribution networks in Southern California and Texas, along with a growing portfolio of LNG export and energy infrastructure projects tied to Mexico and the Gulf Coast. For fiscal year 2025, Sempra reported revenue of roughly $13.7 billion and employed about 16,000–28,000 people across its consolidated and equity-method subsidiaries (headcount varies by reporting convention, since Oncor and Sempra Infrastructure are only partly owned). Collectively, Sempra's utilities and infrastructure businesses serve tens of millions of consumers, making it a systemically important supplier of gas and electricity in two of the country's largest state economies.

What They Do & How They Make Money

Sempra makes money primarily as a regulated utility holding company: its subsidiaries own the poles, wires, pipelines, and storage facilities that deliver electricity and natural gas to homes and businesses, and state regulators (the California Public Utilities Commission and the Public Utility Commission of Texas) set the rates those utilities are allowed to charge, guaranteeing a regulated return on the capital they invest in grid and pipeline infrastructure. This "rate base" model means Sempra's earnings grow largely by investing capital in infrastructure upgrades, grid modernization, and reliability projects, which regulators then allow the company to recover, plus a return, through customer rates over time. Beyond traditional utility ratemaking, Sempra Infrastructure earns revenue from long-term, contracted agreements to liquefy and export natural gas (LNG) to global buyers, as well as from pipelines, energy marketing, and renewable and clean-energy infrastructure — providing a faster-growing, more commercially oriented complement to the stable, regulated utility base.

Business Segments

Sempra reports results across three primary segments:

Sempra California — Encompasses San Diego Gas & Electric (SDG&E) and Southern California Gas Company (SoCalGas). SDG&E provides electric and natural gas service to roughly 3.6–3.7 million consumers in San Diego and southern Orange counties, while SoCalGas is the largest natural gas distribution utility in the United States, serving approximately 22 million consumers across central and Southern California. This segment is Sempra's largest source of stable, rate-regulated earnings and is investing heavily in wildfire mitigation, grid hardening, and emerging hydrogen infrastructure (e.g., the proposed Angeles Link hydrogen pipeline).
Sempra Texas Utilities — Consists primarily of Sempra's approximately 80% economic interest in Oncor Electric Delivery, the largest electric transmission and distribution utility in Texas, serving about 13 million people across a service territory that includes Dallas-Fort Worth. Oncor's rapid rate-base growth, driven by data-center and industrial demand growth and broader Texas grid buildout, has made this segment an increasingly important growth driver for Sempra.
Sempra Infrastructure — Develops, owns, and operates LNG liquefaction and export terminals (such as Cameron LNG and Port Arthur LNG), natural gas pipelines, and clean-energy infrastructure primarily serving Mexico and global LNG markets. This is Sempra's most capital-intensive growth segment and the one most exposed to global commodity markets, project execution risk, and long-term offtake contracts rather than traditional utility ratemaking.

Sempra periodically evaluates and has explored partial monetizations (minority equity stake sales) of both Sempra Infrastructure and Sempra Texas assets to fund its multi-year capital plan, which has exceeded $10 billion in annual capital expenditures in recent years.

Competitors

Regulated utility peers: Duke Energy, Dominion Energy, American Electric Power (AEP), Southern Company, Exelon, Edison International (parent of Southern California Edison, a direct SDG&E-adjacent competitor for California policy influence though not a direct customer competitor), Consolidated Edison, and NextEra Energy — all large, multi-state regulated electric and gas holding companies competing for capital, regulatory favor, and investor attention as "yield plus growth" utility stocks.
Texas transmission peers: CenterPoint Energy and other Texas-regulated transmission and distribution utilities operating under ERCOT.
LNG and energy infrastructure competitors: Cheniere Energy, Freeport LNG, Venture Global LNG, Kinder Morgan, and Williams Companies compete with Sempra Infrastructure for LNG export capacity, offtake customers, and pipeline development opportunities.
Natural gas distribution: Other large gas utilities such as Southwest Gas and regional distribution companies compete indirectly for regulatory and policy influence, though gas and electric utilities are generally geographic monopolies rather than head-to-head competitors for the same customers.

Competitive Position

Sempra's core competitive advantage is structural rather than commercial: as a regulated utility monopoly in its California and Texas service territories, it faces no direct competition for delivering electricity or gas to its existing customer base, and its earnings are largely insulated from commodity price swings because regulators allow cost pass-throughs and guaranteed returns on prudent capital investment. Its scale — spanning the two largest and fastest-growing state economies in the U.S. — gives it exposure to structurally rising electricity demand from data centers, electrification, and population growth, particularly through Oncor's Texas growth. Its Infrastructure segment further diversifies earnings toward global LNG demand, positioning Sempra to benefit from North America's expanding role as a global gas exporter.

Key risks include California wildfire liability exposure (a major concern for California utilities generally, following costly wildfire litigation across the sector), regulatory and rate-case risk in both California and Texas, the execution risk and capital intensity of large LNG projects (cost overruns, permitting delays, and offtake contract risk), interest-rate sensitivity given Sempra's heavy reliance on debt-financed capital spending, and political/regulatory uncertainty around clean-energy transition mandates in California. Sempra's dependence on continued constructive regulatory outcomes and its high multi-year capital expenditure plan (which requires ongoing external financing, including potential equity stake sales in its subsidiaries) are also watched closely by credit rating agencies and investors.
