About Sempra

Sempra is a North American energy infrastructure holding company organized around three regulated utility platforms and a majority-owned LNG export business. Its Southern California Gas Company subsidiary is the largest natural gas distribution utility in the United States, serving residential, commercial, and industrial customers across a broad swath of central and southern California. San Diego Gas & Electric provides bundled electric and gas service to San Diego County and southern Orange County. Sempra's Texas platform, Oncor, is one of the largest regulated electric transmission and distribution utilities in the country, serving the Dallas-Fort Worth metroplex and much of the state. Sempra Infrastructure develops and operates liquefied natural gas export terminals, cross-border pipelines, and related energy infrastructure, primarily along the U.S. Gulf Coast and in Mexico.

Investors track the pace and outcome of rate cases at the California Public Utilities Commission and the Public Utility Commission of Texas, since authorized returns on equity and approved capital plans determine earnings growth at the utility segments. Wildfire liability exposure at the California subsidiaries remains a structural concern despite state-level cost-recovery mechanisms. Oncor is not wholly owned, which affects the share of Texas earnings Sempra retains. Sempra Infrastructure's growth rests on long-term take-or-pay LNG offtake contracts and the ability to reach final investment decisions on new liquefaction trains. Capital allocation is dominated by a multi-year utility capital plan requiring substantial external financing, and the company's index membership in major utility benchmarks shapes ownership.

Sempra was formed in 1998 through the merger of Pacific Enterprises, the parent of Southern California Gas, and Enova Corporation, the parent of San Diego Gas & Electric, uniting two long-established California gas and electric utilities under a single holding company headquartered in San Diego. Over the following two decades the company expanded into Mexican energy infrastructure through IEnova, into commodity trading through its former partnership with RBS, and into U.S. LNG export through the Cameron facility in Louisiana. In 2018 Sempra acquired a controlling interest in Oncor after Energy Future Holdings' bankruptcy. The company subsequently divested South American utility holdings, took IEnova private, and consolidated its non-utility businesses into the Sempra Infrastructure platform, bringing in minority partners.

The regulated utilities earn revenue primarily by delivering gas and electricity to captive retail and wholesale customers at rates set by state commissions, with returns tied to approved rate base, authorized capital structure, and allowed return on equity. Decoupling mechanisms in California separate revenue from volumetric sales, while Texas transmission and distribution rates recover approved investment through periodic filings. Sempra Infrastructure earns fees under long-dated contracts with international energy majors, national oil companies, and utilities that reserve liquefaction capacity or pipeline throughput. Competitive position rests on franchise service territories that face no direct utility rival, on the scarcity of permitted LNG export capacity, and on established cross-border pipeline corridors linking Texas gas supply to Mexican demand centers.
