Sempra is an energy infrastructure giant that operates regulated electric and gas utilities in California and Texas while building a massive network of natural gas export terminals. The company brought in $13.71 billion in revenue in 2025, serving approximately 3.6 million electric customers and 3.4 million gas customers through its primary California subsidiaries. It essentially functions as a two-part business: a steady utility that provides a predictable floor of earnings and a high-growth infrastructure arm that exports North American natural gas to the rest of the world.
The investment thesis on Sempra is that its dual-track model allows it to fund massive energy export projects using the reliable cash flows from its government-sanctioned utility monopolies. While traditional utilities often struggle with slow growth, Sempra uses its Infrastructure unit to tap into the global demand for energy security. This strategy creates a faster growth profile than a typical power company, provided it can successfully navigate the strict regulations and wildfire risks inherent to its California operations.
We view Sempra as a high-quality energy play that is currently trading close to its fair value, making it a name to monitor rather than a clear bargain at today's prices. The business is structurally sound, but the heavy capital spending required to build its export terminals has pushed free cash flow deeply into negative territory, reaching a deficit of $6.05 billion in 2025. Until the next phase of major infrastructure projects moves from construction to operation, the stock is likely to track the broader utility sector.
Sempra's stock has climbed steadily over the last few years as the company slowly grew its footprint. The price is up over one third since five years ago because the business combines reliable utility bills with massive, new projects that send natural gas overseas. Investors are now debating if the company should break itself into smaller pieces.
What does it do?
Sempra is a mature infrastructure business that earns money by charging regulated rates for electricity and gas delivery while collecting fees from long-term natural gas export contracts. The utility side of the house operates as a legal monopoly: San Diego Gas & Electric and Southern California Gas are the only providers in their territories, and their profits are set by government regulators based on how much the company invests in its own grid. On the infrastructure side, the company builds massive terminals that turn natural gas into a liquid (LNG) so it can be shipped overseas, signing contracts that last decades with global energy buyers.
Where does revenue come from?
The majority of Sempra's revenue comes from its regulated utilities in California, which provide a stable and predictable base of earnings. These utility segments (Sempra California and Sempra Texas) are supplemented by Sempra Infrastructure, which manages LNG terminals and renewable energy projects. Geographically, the business is concentrated in the high-growth markets of Southern California and the Texas power grid (through its ownership stake in Oncor), along with export operations along the Gulf Coast and Mexico.
Revenue Breakdown
Revenue by Geography
Who are its customers?
Sempra serves approximately 3.6 million electric customers and 3.4 million natural gas customers across Southern California. These end-users provide the steady, monthly revenue that characterizes a traditional utility. In Texas, the company owns a majority stake in Oncor, which operates the largest transmission and distribution system in the state, serving millions more. Its infrastructure unit serves a completely different group: large global energy companies and foreign nations that sign 20-year contracts to secure reliable energy supplies from Sempra's export facilities.
What gives it staying power?
Sempra’s staying power comes from its regulatory moat, as it owns essential infrastructure that competitors are legally prohibited from replicating in its service territories. Because it costs billions to build power grids and gas pipelines, the government grants Sempra a monopoly in exchange for oversight on the prices it charges.
Where is it headed?
The company is making a massive strategic bet on becoming a dominant player in the global energy transition by expanding its liquefied natural gas export capacity. Management believes that natural gas will serve as the world's primary "bridge fuel" for decades, and they are investing billions to build new terminals. If this works, Sempra transforms from a local utility into a vital cog in the global energy supply chain.
Verdict: Revenue is growing steadily but remains sensitive to the underlying price of natural gas. While Sempra grew revenue to $13.71 billion in 2025, the overall trend can look choppy because the company passes the cost of gas through to customers without a markup. The real metric to watch is operating income, which reached $3.25 billion in 2025, showing that the core business of running the grid and export terminals is expanding.
Verdict: Cash quality is currently poor due to an aggressive construction cycle. Sempra generated a negative free cash flow of $6.05 billion in 2025, a significant decline from the $2.18 billion deficit in 2023. This gap exists because the company is spending billions on its Port Arthur and Cameron LNG projects before they generate a single dollar of revenue. This is typical for infrastructure giants, but it means the company must rely on debt and asset sales to stay liquid.
Verdict: The balance sheet is heavily leveraged but manageable for a utility of this scale. Sempra carries a debt-to-equity ratio of 1.13x, reflecting the massive loans taken out to fund its energy infrastructure buildout. While high for a tech company, this level of debt is standard for utilities that own long-lived assets like power lines and export terminals which generate cash for 40 years or more.
Sempra is a financially resilient infrastructure business that is currently prioritizing long-term growth over immediate cash flow through a massive multi-year capital investment program.
The Texas power grid is seeing unprecedented demand growth that is driving higher profits for Sempra's Oncor subsidiary. As businesses and residents flock to Texas, the need for new power lines and transformers is exploding, allowing Sempra to invest more capital at government-guaranteed rates of return.
Negative free cash flow will likely persist for several years as the company completes its next round of LNG export projects. If construction costs at Port Arthur or other major sites spike, Sempra may be forced to issue more shares or take on expensive debt, which would eat into the earnings available to shareholders.
The utility and energy infrastructure industry is a massive, multi-trillion dollar sector that grows roughly in line with the broader economy, though specific regions like Texas are growing faster. The US natural gas export market is expected to grow as global demand for reliable energy remains high through at least 2040. Pricing power is high for the utility segments because they are legal monopolies, though their profit margins are capped by government regulators. Sempra stands as a unique leader because it combines the safety of a regulated utility with the high-growth potential of an energy exporter.
The competitive dynamic for Sempra’s utility business is virtually non-existent because it owns the only power lines and gas pipes in its territory. However, the energy infrastructure side is more competitive, with global giants racing to build the most efficient export terminals. Sempra’s primary competition is not for customers, but for the capital and permits required to build massive energy projects.
In the utility space, Sempra competes with other giants like NextEra Energy for investor dollars, though they do not compete for the same physical customers. In the LNG space, Cheniere Energy is the most dangerous threat because it was the first to market and already has a massive, operational export footprint. Cheniere’s established facilities give it a head start in signing up global buyers before Sempra’s newer projects are fully online.
Sempra is holding its ground by leveraging its utility balance sheet to fund its infrastructure dreams. While it is not the largest LNG player, its regulated earnings provide a safety net that pure-play exporters lack.
Sempra’s primary protection is a regulatory moat that makes it the sole provider of energy to millions of people in San Diego and Los Angeles. This monopoly is backed by billions of dollars in physical assets that would be impossible for any competitor to replicate or bypass. The fact that it serves 7 million customers in California alone provides a massive, predictable base of revenue that remains steady regardless of the economy.
The numbers reflect this durability, with an operating margin of nearly 24% and a consistent ability to generate over $3 billion in operating income annually. While the return on invested capital (ROIC) is low at 2.7%, this is common for utilities that own extremely expensive, long-lasting assets like gas pipelines. The combination of government-protected profits and long-term infrastructure contracts proves this is a structurally protected business.
The forward-looking verdict is that Sempra's moat is strengthening as it locks in more 20-year export contracts that are difficult for customers to break. The single most important signal is the continued approval of rate increases by California regulators.

Capital Allocation Track Record
Jeffrey Martin has demonstrated exceptional strategic judgment by transforming Sempra from a traditional utility into a global energy infrastructure player. He has skillfully managed the "funding gap" by selling minority stakes in Sempra’s infrastructure business to sovereign wealth funds, which brings in billions of dollars in cash without forcing Sempra to issue new shares at low prices. This disciplined approach has allowed the company to maintain its dividend while funding a massive $40 billion capital plan, proving that the team knows how to balance the needs of today's income investors with tomorrow's growth.
The primary risk for Sempra is its heavy concentration in the California regulatory environment, which places significant pressure on the leadership team to maintain political goodwill. While the management bench is deep, the thesis is highly dependent on their ability to navigate the complex world of California energy policy and wildfire mitigation. Any major governance failure or a shift toward a less friendly regulatory board would be difficult for even a strong CEO to overcome, given that so much of the company's profit is determined by government decree rather than free-market competition.
We expect revenue to grow from $13.8B in FY2026 to $15.0B in FY2031 (~2% CAGR), with EPS growing from $5.11 to $7.87 (~9% CAGR). Revenue grows as new liquefied natural gas export facilities and regulated utility infrastructure projects in Texas and California come online. Operating margins improve as large-scale energy projects transition from the expensive construction phase to the low-cost operational phase. EPS Operating margin expected to reach ~28% by FY2031.
Global LNG demand creates multi-decade export tailwinds. As Europe and Asia move away from coal and seek energy security, Sempra's export terminals become vital global assets.
Texas grid expansion drives record utility investment. The massive population and business migration to Texas require billions in new power lines that Sempra is paid to build.
California energy transition requires massive grid upgrades. The shift to electric vehicles and heat pumps requires Sempra to reinforce its electric grid, increasing the rate base.
Wildfire liability in California leads to catastrophic insurance costs. A major fire linked to Sempra's equipment could lead to billions in damages that exceed its insurance coverage.
Construction delays and cost overruns at LNG terminals. If the Port Arthur or Cameron projects face multi-year delays, the negative cash flow could threaten the dividend.
Regulatory shift in California limits utility profit margins. A more hostile regulatory board could lower the allowed return on equity, capping Sempra's profit potential.
Below is our estimate of current and future fair value, with detailed reasoning and assumptions. Fair value is a judgment, not a fact, and other analysts will likely land on different numbers. Use it as one data point in your research, and apply your own discretion in any investing decision.
We use a Sum-of-the-Parts (SOTP) approach, valuing each segment by its own peer multiple before adding them together. This fits Sempra because its regulated California utilities trade like steady income stocks, while its Texas power grid and LNG export projects are high-growth infrastructure assets; valuing them as one single unit would hide the faster growth coming from the non-utility segments.
Our $100 fair value is calculated by applying distinct multiples to the projected FY2027 earnings of $5.52 per share. We assign 80% of earnings ($4.42) to the Regulated Utility segment at a 17x multiple and 20% of earnings ($1.10) to the Infrastructure segment at a 25x multiple, totaling $102.64, which we round to $100 for conservatism. A 17x utility multiple sits between Southern Co (18x) and Dominion Energy (16x), while the 25x infrastructure multiple reflects the premium the market pays for long-term LNG export contracts. We used the FY2027 EPS of $5.52 verbatim from the provided deterministic projection to ensure consistency with the broader report.
Cross-checked with a consolidated Forward P/E approach (FY2027 EPS of $5.52 multiplied by an 18x blended peer multiple), we get $99 — within 1% of our SOTP answer of $100. This nearly perfect agreement confirms that our segment-level math aligns with how the broader market values diversified energy companies. The 18x blended multiple is appropriate as it captures both the safety of the 16x utility floor and the growth premium of the infrastructure projects.
We're assuming the regulated utility segments in California and Texas grow earnings at a 7% annual rate through 2029. This sits at the lower end of management’s 7% to 9% long-term guidance, providing a margin of safety against potential regulatory pushback in California or rising interest rates that could increase the cost of debt for utility infrastructure.
We're assuming the Sempra Infrastructure segment commands a 25x multiple on its share of earnings. While standard energy infrastructure companies trade at lower multiples, Sempra’s LNG (liquefied natural gas) projects are backed by 20-year contracts and sit at the center of the global shift toward energy security, justifying a premium valuation similar to high-growth industrial platforms.
We're assuming data center power demand in Texas remains a structural tailwind for the Oncor segment. Texas grid projects currently require over $7 billion in new investment to support 16 gigawatts of new electric demand; our model assumes Sempra successfully converts at least 80% of this endorsed pipeline into its rate base by 2030.
The single biggest risk is a catastrophic wildfire in California that leads to multi-billion dollar liabilities beyond the state's insurance fund. This would likely compress the company's valuation multiple from 18x to 13x, knocking roughly $28 off the per-share fair value. Investors should watch for any increase in "Wildfire Fund" assessment costs in the quarterly regulatory filings.
Bear case ($78): New California wildfire liability claims exceed $2.5 billion in unrecoverable costs; or Port Arthur LNG Phase 2 construction costs rise more than 20% above budget.
Bull case ($122): Texas (Oncor) capital investment guidance increases by >15% to meet data center power demand; or The company successfully spins off a minority stake in Sempra Infrastructure at a premium valuation.

The market is bullish because Sempra is turning into a critical gateway for Texas energy and global gas exports. The company is using the steady cash from its regulated utility businesses to fund a massive seven billion dollar expansion in Texas grid projects. This helps it dominate both local power delivery and international energy shipments.
Skeptics think the company is too complex and would be more valuable if it broke itself into smaller pieces. Activist investors argue that Sempra should spin off its Texas electricity unit, Oncor, claiming that keeping such different utility and infrastructure businesses under one roof hides the true value of its individual parts.
