Sempra is an energy company that owns utilities and builds gas pipelines and power infrastructure to deliver electricity and natural gas to millions of people.
Sempra is an energy holding company, a collection of businesses that own the poles, wires, pipes, and gas plants that deliver power and heat to homes and buildings. Most of its money comes from regulated utilities — mainly San Diego Gas & Electric in Southern California and Oncor in Texas — which earn a set, government-approved return for keeping the lights on and the gas flowing. Regulators let these utilities raise prices to cover costs plus a profit, so the business is steady rather than boom-and-bust.
Owning a utility is a bit like owning the toll road rather than the cars on it. Sempra spends billions building and maintaining the wires, poles, and pipes, and then collects a predictable fee from every customer who uses them. That is why utilities are popular with investors who want slow, reliable growth and a dividend instead of wild swings. Sempra also has a big infrastructure arm that builds and owns natural gas pipelines and power plants, including pipelines stretching down into Mexico, plus a liquefied natural gas (LNG) export business on the Gulf Coast that cools gas into a liquid and ships it overseas. The LNG piece is the growth story and the risky one. Sempra has been expanding its Cameron LNG plant in Louisiana and a planned site in Texas, betting that the world — especially Europe and Asia — will keep paying for American gas to replace other fuels. That bet ties part of the company to global energy prices it cannot control, which is a very different business from the safe, regulated utility side. On the utility side, Sempra has been selling off non-core assets to simplify the company and focus on its Texas and California utilities, which is where most of its steady earnings now come from.
In 1998, two big Southern California utilities, Southern California Gas and San Diego Gas & Electric, joined under one roof in a six-billion-dollar merger, creating a company called Sempra. Overnight it became one of the largest regulated utility businesses in the country, serving about 21 million consumers. The idea was simple: two regulated utilities with steady, predictable profits could fund bigger ambitions. The stock started trading on the New York Stock Exchange at just over 28 dollars a share.
The merged company struggled early. Less than two years in, the stock was trading around 17 dollars, far below its debut price, and Sempra responded by cutting its quarterly dividend and launching a plan to buy back up to 36 million shares. Translation: management was trying to steady a ship that had lost its way.
Sempra's bet on a new kind of business took shape when Energía Costa Azul, a terminal on Mexico's Baja California coast, began commercial operations. Its job was to receive liquefied natural gas — gas chilled into a liquid so it can be shipped across oceans on tankers — and turn it back into gas for delivery. Able to process up to a billion cubic feet a day, it became a core growth platform for the company.
Sempra's Mexican subsidiary, IEnova, went public in March 2014, making it one of the first private companies to invest in Mexico's energy sector after reforms opened the market. That same spring, Sempra's stock crossed 100 dollars for the first time. The message was clear: the patient bet on infrastructure was starting to pay.
The bad news arrived with the company's fourth-quarter 2024 results. Revenue missed estimates, Sempra cut its 2025 earnings guidance, and it blamed higher interest and operating costs, mild weather and regulatory headaches. Investors reacted hard: the stock dropped about 19% in a single day, closing near 70 dollars and making Sempra the worst performer in the S&P 500 that day.
Later in 2025, Sempra agreed to sell a 45% stake in its Sempra Infrastructure unit to KKR for 10 billion dollars, valuing the whole unit at about 22 billion. The point was a big pivot: Sempra wanted to focus its money on regulated utilities in Texas and California, and by 2027 it expected roughly 95% of earnings to come from those steady U.S. utility businesses.
As the KKR deal neared its close, Sempra shuffled its leadership. CFO Karen Sedgwick was named CEO of Southern California Gas, Sempra Infrastructure CEO Justin Bird became Sempra's CFO, and Bob Patel, former CEO of LyondellBasell, was named incoming CEO of Sempra Infrastructure as the consortium took a 65% stake, leaving Sempra with 25%.
Sempra Infrastructure kept growing its LNG business, signing a 20-year deal to sell about 0.8 million tonnes of LNG a year to Petrobras from Port Arthur LNG Phase 2 — its first South American customer. The project, sanctioned in 2025, is expected to add about 13 million tonnes of capacity, with the first trains running in 2030 and 2031. Behind it all is a roughly 65-billion-dollar capital plan, powered by Texas grid demand and long-term contracted LNG.
Sempra is headquartered in San Diego, and its Oncor utility in Texas has become one of its most valuable pieces, serving a fast-growing slice of the state. The main thing to understand is the split personality: a boring, dependable regulated utility that keeps the cash flowing, and a more volatile infrastructure and LNG business that offers upside but also exposure to energy markets and politics. Sempra pays a dividend and pours most of its cash back into building new pipelines and power lines, because in the utility world, spending money on the network is how you earn a bigger regulated profit later.
