Oncor (Sempra) (SRE) Q2 2026 earnings review
Blowout Q2 Masked by Surcharge Amid Explosive AI Load Demand
Oncor's Q2 headline numbers are optically phenomenal—Revenue accelerated by 25% to $2.06B, and Net Income surged 65% to $428M. However, earnings quality is distorted by a one-time $181M revenue catch-up from a retroactive base rate implementation. Stripping this out, core operating income was effectively flat YoY, weighed down by rising depreciation and O&M expenses. The real story lies off the income statement: Oncor is executing an unprecedented infrastructure buildout to support a staggering 282 GW data center queue. CapEx has spiked 47% YoY to $4.15B in H1, driving massive negative free cash flow. While the long-term utility growth thesis remains bulletproof—backed by $5.9B in customer collateral—the near-term reality is a severe capital burn that requires flawless operational execution and parent Sempra's ongoing asset sales to fund.
🐂 Bull Case
The new Unified Tracker Mechanism (UTM) and a 9.75% authorized ROE base rate are actively printing cash, with UTM alone generating $102M in Q2, up 436% YoY.
Holding $5.9B in customer collateral protects the balance sheet from stranded asset risk, bridging the gap between theoretical AI hype and regulated utility reality.
🐻 Bear Case
A staggering $4.15B in H1 CapEx against merely $652M in operating cash flow demands massive external funding, heavily relying on Sempra's pending M&A.
Without the retroactive $181M surcharge, core operating leverage is absent as operating and maintenance costs (+24%) outpace organic volume growth.
⚖️ Verdict: ⚪
Neutral to Bullish. The sheer volume of load growth guarantees long-term rate base expansion, but the severe cash burn and artificially inflated Q2 net income warrant caution in the immediate term.
Key Themes
AI Load Transitioning from Queue to Construction
The massive data center hype is beginning to materialize into physical infrastructure. Oncor's LC&I queue reached a staggering 737 requests, including 282 GW specifically from data centers. To manage this unprecedented load without breaking the ERCOT grid, a new system-wide 'Batch Zero' engineering sequence has been approved by the PUCT, targeting 44 GW of eligible large-load requests. This represents a critical technological and planning pivot from theoretical queue numbers to engineered grid integration.
Headline Blowout Contradicted by Surcharge Masking
Management's narrative of a 65% jump in Net Income requires heavy discounting. The PUCT-approved base rate settlement resulted in a $181 million retroactive surcharge recognized entirely in Q2. If we strip out this one-time revenue infusion, Oncor's adjusted operating income sits at approximately $437 million—virtually flat compared to the $432 million printed in 25Q2. Rising depreciation ($352M vs $290M) and O&M expenses completely consumed the organic volume growth.
Unified Tracker Mechanism (UTM) Printing Cash
The implementation of HB5247 is fundamentally transforming Oncor's cash cycle. The Unified Tracker Mechanism (UTM) allowed Oncor to recognize $102 million in Q2, a massive acceleration from just $19 million a year ago. This structural change permits annual interim rate adjustments, effectively erasing the historical regulatory lag that previously suppressed returns during high-capex cycles.
Extreme Capital Intensity Pressuring Free Cash Flow
Oncor's status as a premier growth engine comes at a severe cash cost. H1 2026 CapEx spiked to $4.15 billion against merely $652 million in operating cash flow, driving an implied free cash flow deficit of nearly $3.5 billion. This staggering burn rate required $1.85 billion in parent contributions. Sempra's ability to fund this without shareholder dilution hinges entirely on the successful Q2/Q3 closure of its Sempra Infrastructure stake sale to KKR.
Financial Fortressing via $5.9B in Collateral
The primary bear argument against utility AI infrastructure is stranded asset risk if data centers abruptly cancel projects. Oncor has systematically de-risked this by hoarding $5.9 billion in customer collateral for active generation and LC&I transmission requests. This functions as an aggressive financial fortress, ensuring ratepayers and the balance sheet are protected from speculative vaporware.
Macro Reality: ERCOT Peak Constraints
As ERCOT set new peak demand records this summer, the macro challenge shifted from financial capacity to physical reality. The addition of 44 GW in the Batch Zero process alone exceeds the entire grid capacity of many regional operators. While Oncor successfully placed the 165-mile Delaware Basin Stage 2 project in service, coordinating the build-out of new IPP generation with massive high-voltage transmission lines introduces severe logistical, labor, and supply chain execution risks.
Other KPIs
Accelerating. Up 23.6% YoY from $368M in 25Q2. This sharp increase reflects the intense physical labor and maintenance required to operate an rapidly expanding network during record summer demand, offsetting much of the organic top-line margin expansion.
Accelerating. Jumped 31% YoY from $387M, aided by a combination of new base rates, population growth (16,200 new premises in Q2), and an 8% increase in cooling degree days. Weather normalization still showed an impressive 35.4% YoY distribution base revenue gain.
Guidance
Decelerating. Out of the $212 million deferred revenue surcharge awarded by the PUCT, $181 million was front-loaded into Q2. This implies sharp sequential deceleration for Q3 and Q4 top-line growth as the artificial base rate catch-up boost fades.
Accelerating. The $4.15 billion deployed in H1 implies an annualized run rate of $8.3 billion. To hit the $9.0 billion target established in previous quarters, Oncor will need to meaningfully accelerate its capital deployment in the back half of the year, which carries execution risk amidst tight labor markets.
Key Questions
Normalized Run-Rate Visibility
With $181M of the surcharge artificially inflating Q2, how should investors model normalized operating margins for H2 2026 now that both the new base rates and the UTM are simultaneously running?
Grid Reality Check
The LC&I queue boasts 282 GW of data center load. Given ERCOT's physical generation constraints and the 'Batch Zero' limits, what percentage of this queue do you realistically expect to reach commercial operation by 2030?
Funding Contingencies
CapEx outpaced operating cash flow by $3.5 billion in H1. If Sempra's Infrastructure stake sale to KKR faces extended regulatory delays beyond Q3, what is the exact contingency plan for funding Oncor's $9.0 billion annual capital budget?
