## Summary

Sempra (SRE) reported ~$17.1B revenue in FY2024. Major utility holding company owning SoCal Gas, SDG&E, and growing LNG export infrastructure in Texas and Louisiana. HQ: San Diego.

## Company Overview

Sempra is a leading energy infrastructure holding company with regulated utility operations in California and international liquefied natural gas (LNG) export infrastructure. The company's two California utilities — Southern California Gas Company (SoCalGas, the nation's largest natural gas distribution utility) and San Diego Gas & Electric (SDG&E, serving the San Diego region with both electricity and gas) — provide the regulated earnings base, while Sempra Infrastructure owns and operates LNG export facilities on the Gulf Coast (Energia Costa Azul in Baja California and Port Arthur LNG in Texas).

Sempra reported approximately $17.1 billion in revenue in FY2024, with regulated utility earnings from SoCalGas and SDG&E representing the majority. The California utility business provides steady regulated returns through approved rate cases, though it faces increasing wildfire liability risk (particularly SDG&E, whose service territory includes high-fire-risk areas) and regulatory pressure from California's aggressive decarbonization mandates requiring gas distribution infrastructure to transition. SoCalGas is navigating this challenge by developing hydrogen blending infrastructure and investing in renewable natural gas (RNG) projects.

Sempra Infrastructure's LNG business is a significant long-term growth catalyst: the Cameron LNG export facility in Louisiana (in which Sempra holds a stake) is operational, and Port Arthur LNG in Texas represents one of the largest LNG export projects under development in North America. With global LNG demand driven by Europe's energy security imperative and Asia's clean energy transition, Sempra's Gulf Coast LNG position could be a transformative earnings contributor over the next decade.

## Frequently Asked Questions

### What does Sempra own?
Sempra owns Southern California Gas (nation's largest natural gas utility), San Diego Gas & Electric (electricity and gas for San Diego), and Sempra Infrastructure (LNG export facilities including Cameron LNG and Port Arthur LNG in development).

### What is SoCalGas?
Southern California Gas Company is the nation's largest natural gas distribution utility, delivering gas to 22 million customers across a 24,000 square mile service territory in central and Southern California. It is a key Sempra subsidiary and regulated earnings anchor.

### What is Sempra's ticker?
Sempra trades on the NYSE under the ticker SRE.

### What is Port Arthur LNG?
Port Arthur LNG is Sempra Infrastructure's LNG export terminal under development in Port Arthur, Texas — one of the largest planned LNG export projects in North America. It will liquefy domestic natural gas for export to Europe and Asia.

### How does Sempra's LNG business work?
Sempra Infrastructure liquefies natural gas at its Cameron LNG facility in Louisiana and the developing Port Arthur LNG project in Texas, loading it onto specialized tankers for export to European and Asian buyers. LNG (liquefied natural gas) enables global natural gas trade that would be impossible via pipeline, linking US production to global demand.

### What is SDG&E and what makes it unique?
San Diego Gas & Electric is an integrated electric and gas utility serving 3.7 million customers in San Diego and southern Orange County. SDG&E has one of the highest penetrations of rooftop solar in the US and has been an innovation leader in demand response, distributed energy integration, and wildfire mitigation technology.

### How does Sempra manage wildfire risk at SDG&E?
SDG&E has invested over $1B in wildfire mitigation since the 2007 San Diego wildfires, deploying the largest network of weather stations and high-definition cameras of any US utility, installing covered conductor in high-risk areas, and implementing public safety power shutoffs. SDG&E is considered an industry leader in utility wildfire risk management.

### What is Sempra's earnings growth strategy?
Sempra targets 6–8% annual earnings per share growth driven by regulated utility rate base investment at SoCalGas and SDG&E, and LNG infrastructure development at Sempra Infrastructure. The LNG business provides higher-growth exposure than regulated utilities, but with greater capital commitment and longer development timelines before earnings contribution.
