Oncor (Sempra Texas) (SRE) Q1 2026 earnings review
Data Center Boom and Favorable Regulation Drive Double-Digit Growth
Oncor is capitalizing on the Texas infrastructure boom. Driven by a staggering 271 GW data center interconnection queue, the company is ramping its 2026 capital budget to $9.0 billion. Crucially, favorable regulatory outcomes—including a new base rate approval adding $560 million and a Unified Tracker Mechanism (UTM) filing—are ensuring that this massive capital deployment translates directly to the bottom line. Net Income accelerated 17% YoY to $212 million, overcoming a sharp drop in residential volumes caused by mild winter weather.
🐂 Bull Case
The PUCT approved an unopposed base rate settlement (+8.7% revenue boost) starting June 1, 2026. Coupled with the new UTM filings, Oncor is converting capital investments into cash flow faster than ever.
With 697 active transmission requests—including 271 GW from data centers—Oncor has secured a multi-decade runway for guaranteed capital deployment.
🐻 Bear Case
Funding a $9.0 billion CapEx plan requires immense leverage. Q1 interest expense jumped 23% YoY to $227 million. If interest rates remain elevated, financing costs will severely drag down profitability.
Despite overall growth, residential volumes actually fell 10.4% YoY due to a 38% drop in heating degree days, proving earnings are still highly susceptible to uncontrollable climate factors.
⚖️ Verdict: 🟢
Bullish. While negative free cash flow and rising debt are notable, Oncor's ability to seamlessly pass costs to ratepayers via constructive Texas regulation makes the $9 billion capital plan a guaranteed earnings engine.
Key Themes
Data Centers Accelerating the Transmission Queue
The macro AI narrative is directly hitting Oncor's physical grid. The active transmission Large Commercial & Industrial (LC&I) queue surged to 697 requests. Of this, 271 GW is exclusively from data centers. For context, this data center queue has accelerated from 156 GW a year ago, forcing ERCOT and Oncor to develop a new 'batch study process' specifically to handle hyper-scaler capacity needs.
Base Rate Review Settled
Accelerating. The PUCT issued an order on April 17 approving an unopposed settlement that increases Oncor's base revenues by ~$560 million (an 8.7% bump over the 2024 test year). It locks in a 9.75% authorized ROE and a 56.5% debt to 43.5% equity structure. This takes the guesswork out of Oncor's near-term profitability.
Unified Tracker Mechanism (UTM) Execution
Accelerating. The UTM legislation passed last year is working exactly as intended. Oncor filed to update interim rates to reflect $4.4 billion in 2025 net capital investments. If approved, this single filing will generate a net revenue increase of ~$550 million, drastically reducing the regulatory lag that historically plagued utility earnings.
Weather Masks Underlying Residential Weakness
Reversing. A specific data point contradicts the broad growth narrative: Residential electric volumes collapsed 10.4% YoY (10,086 GWh down from 11,253 GWh). Management blames milder weather, citing a drop in heating degree days from 572 to 355. While commercial volume (+8.5%) offset this, it highlights that a significant portion of base revenues remains at the mercy of seasonal weather patterns.
Ballooning Interest Expense
Decelerating profitability profile. Oncor's aggressive expansion relies heavily on debt markets. In Q1 alone, the company issued $1.6 billion in new senior secured notes. Consequently, Q1 interest expense surged 23% YoY to $227 million. As the $9.0 billion CapEx plan executes throughout the year, interest burdens will continue to swell, eating into operating income gains.
CapEx Execution and Supply Chain Risk
Deploying $9.0 billion in a single year (a 25% YoY increase) presents immense logistical hurdles. Oncor built/upgraded nearly 700 circuit miles in Q1 and is beginning 765 kV import transmission grading for the Permian Basin Reliability Plan (PBRP) in Q2. Securing high-voltage transformers, switchgear, and skilled labor at this scale introduces tangible schedule and cost overrun risks.
Other KPIs
Accelerating. Up massively from $194 million in 25Q1. The increase was driven by higher net income, $98M in UTM regulatory asset recoveries, and a significant $202M influx of customer deposits (up from an outflow of $17M a year prior), largely tied to collateral for the massive interconnection queue.
Accelerating. Up 51% YoY compared to $1.35 billion in 25Q1. This massive outlay outstripped operating cash flow by $1.5 billion, underscoring Oncor's intense reliance on external debt financing to fund the Texas grid expansion.
Guidance
Accelerating. Represents a roughly 25% increase over 2025 actual CapEx. Management explicitly attributes this surge to sustained load growth and system needs, cementing Oncor's position in a multi-year super-cycle.
Accelerating. Management expects the newly approved PUCT base rate order to increase second-quarter 2026 earnings directly by approximately $70 million, offering high visibility into near-term margin expansion.
Stable. Requested in April 2026 to cover $4.4 billion of 2025 capital investments. A final order and updated rates are anticipated in the second half of 2026.
Key Questions
Supply Chain Preparedness
With the 2026 CapEx budget ramping by 25% to $9.0 billion, what specific long-term commitments or vendor agreements are in place to ensure availability of 765 kV equipment and high-voltage transformers?
Collateral and Stranded Asset Risk
Oncor holds $4.0 billion in customer collateral for active POI requests. If a hyper-scaler or data center developer cancels a project midway through transmission construction, how effectively does this collateral cover the actual physical stranded asset risk?
Weather-Normalized Residential Demand
Reported residential volumes fell 10.4% YoY due to a mild winter. Can you quantify what the underlying, weather-normalized volume growth for the residential segment was in Q1?
