## Geographic presence

Sempra is headquartered in San Diego, California. Its California utilities serve distinct parts of the state: San Diego Gas & Electric’s approximately 4,100-square-mile service territory covers San Diego County and part of Orange County, while Southern California Gas serves an approximately 24,000-square-mile area across Southern California and parts of central California. SoCalGas’s territory excludes San Diego County, Long Beach and a desert area of San Bernardino County. [22](https://app.finbar.com/go?id=T1471668)[23](https://app.finbar.com/go?id=P72704132)[24](https://app.finbar.com/go?id=P93410447)

In Texas, Sempra’s Oncor investment has transmission and distribution assets in more than 120 counties and 400 municipalities; its Sharyland investment includes south Texas transmission assets and a connection to Mexico. Sempra Infrastructure has assets in both the United States and Mexico. Its LNG facilities and projects include sites in Hackberry, Louisiana; near Port Arthur, Texas; and Baja California, Mexico. Its Mexican operations also include natural-gas distribution zones in Mexicali, Chihuahua and La Laguna-Durango, as well as refined-products storage in several states. The reported revenue breakdown is by business segment rather than by country or state.

## Business segments

Sempra reports three business segments: Sempra California, Sempra Texas Utilities and Sempra Infrastructure. Sempra California comprises its regulated utilities SDG&E, which provides electricity and natural gas service, and SoCalGas, which provides natural gas service. Together they serve customers across much of Southern California. [33](https://app.finbar.com/go?id=P63339346)[34](https://app.finbar.com/go?id=P101242803)[23](https://app.finbar.com/go?id=P72704132)[24](https://app.finbar.com/go?id=P93410447)

Sempra Texas Utilities holds equity-method interests in Oncor Holdings and Sharyland Holdings. Their underlying utilities primarily transmit and distribute electricity in Texas; Oncor also operates an extensive distribution network. Sempra Infrastructure develops, operates and invests in energy infrastructure, principally LNG facilities, natural gas networks and lower-carbon energy projects in the U.S. and Mexico. [35](https://app.finbar.com/go?id=P22702452)[36](https://app.finbar.com/go?id=P12002042)[25](https://app.finbar.com/go?id=P62718668)[2](https://app.finbar.com/go?id=P60603707)[37](https://app.finbar.com/go?id=P90372870)

Measured by reported segment assets at year-end 2025, the approximate mix was **54% California, 16% Texas Utilities and 30% Infrastructure**. On a different measure, their shares of total *segment earnings before parent-level items* were approximately **52%, 22% and 26%**, respectively, in 2024. Texas Utilities’ equity-method accounting means its contribution is more meaningfully reflected in earnings and assets than in consolidated segment revenue. [38](https://app.finbar.com/go?id=T8716545)[39](https://app.finbar.com/go?id=T7386412)[35](https://app.finbar.com/go?id=P22702452)

## Company history

Sempra Energy was formed in 1998 through the merger of Pacific Enterprises, parent of Southern California Gas, and Enova Corporation, parent of San Diego Gas & Electric. The combination brought the two Southern California utilities under one holding company. [40](https://www.sec.gov/Archives/edgar/data/1032208/000008652198000002/0000086521-98-000002.txt) Sempra subsequently expanded beyond those utilities into energy trading and infrastructure. In 2010, it agreed to acquire natural-gas pipeline and infrastructure assets in Mexico, and in 2013 its Mexican subsidiary, IEnova, launched an initial public offering. [41](https://investor.sempra.com/static-files/b17377e4-0dbb-45b7-bfc5-fd98b4eded70)[42](https://www.sec.gov/Archives/edgar/data/1032208/000008652113000018/ex991.htm)

In 2018, Sempra acquired a majority stake in Oncor, a Texas electric transmission and distribution utility, substantially expanding its U.S. regulated-utility holdings. [43](https://www.sempra.com/sempra-energy-completes-acquisition-majority-stake-oncor) It sold its utility businesses in Peru and Chile in 2020, then brought its LNG and Mexican energy businesses together under the Sempra Infrastructure platform in 2021.
