ONCOR REPORTS SECOND QUARTER 2025 RESULTS

DALLAS (August 7, 2025) — Oncor Electric Delivery Company LLC (Oncor) today reported net income of $259 million for the three months ended June 30, 2025, compared to net income of $251 million in the three months ended June 30, 2024. The increase in net income of $8 million was driven by overall higher revenues primarily attributable to updated interim rates to reflect increases in invested capital, an increase in other regulated revenues recognized related to Oncor’s system resiliency plan (SRP) and the unified tracker mechanism (UTM) established by Texas House Bill 5247, and customer growth, partially offset by higher interest expense and depreciation expense associated with increases in invested capital, and higher operation and maintenance expense. Financial and operational results are provided in Tables A, B, C, D, and E below.

“As we move through the peak summer season, our team remains steadfast in its commitment to safely delivering reliable power to the more than 13 million Texans we serve,” said Oncor CEO Allen Nye. “We work year-round to strengthen and modernize our system to meet the growing demands across our expanding service territory. This past quarter, Oncor filed a rate case to recover historical storm-related costs, support the recruitment, training, and safety of our large and active workforce, and secure materials and equipment at an unprecedented scale. A constructive outcome, combined with supportive legislation passed during the 89th Texas Legislature, will enhance our financial strength and position Oncor to raise the capital necessary to serve our customers and the State during this period of exceptional growth in Texas.”

Oncor also reported net income of $440 million for the six months ended June 30, 2025, compared to net income of $476 million in the six months ended June 30, 2024. The decrease in net income of $36 million was driven by higher interest expense and depreciation expense associated with increases in invested capital and higher operation and maintenance expense, partially offset by overall higher revenues primarily attributable to updated interim rates to reflect increases in invested capital, customer growth, an increase in other regulated revenues recognized related to the SRP and the establishment of the UTM, and higher customer consumption primarily attributable to weather.

Operational Highlights

During the second quarter, Oncor continued work on its company record $7.1 billion annual capital expenditure plan for 2025. Key operational updates during the second quarter included implementation of important components of Oncor’s SRP, such as, enhanced wildfire risk modeling, completion of approximately 2,000 miles of resiliency assessments (primarily in wildfire mitigation zones), and the acquisition of approximately 20,000 miles of LiDAR data and 2,800 miles of drone imagery.

Additionally, Oncor’s team has been hard at work on planning and other pre-construction work related to the 765 kV Electric Reliability Council of Texas, Inc. (ERCOT) Strategic Transmission Expansion Plan (STEP), including Oncor’s import lines in the Permian Basin Reliability Plan (PBRP), and submitting the remainder of the 765 kV Eastern portion of STEP to the ERCOT Regional Planning Group in conjunction with other utilities. The joint filings for the Eastern portion of STEP outline approximately $10 billion of projects. The joint filings did not address the remaining lower voltage transmission system upgrades and new transmission facilities needed, which ERCOT estimates will have a cost of $8 – $10 billion. Oncor anticipates it will be responsible for building a significant amount of the total Eastern portion of STEP. During the quarter Oncor filed four new Certificates of Convenience and Necessity (CCNs) for needed transmission projects building on the seven CCNs filed in the first quarter of 2025. Four previously filed projects also received regulatory approvals in the second quarter, clearing the way for new substations and line upgrades to proceed.

In the second quarter of 2025, Oncor built, rebuilt, or upgraded approximately 590 circuit miles of transmission and distribution lines and increased premises by nearly 20,000, reflecting ongoing population and business growth in Texas. Active transmission point-of-interconnection (POI) requests continued to rise in the second quarter, remaining well above year-ago levels. As of June 30, 2025, Oncor’s active large commercial and industrial (LC&I) interconnection queue was approximately 38% higher than at the same time last year. As of June 30, 2025, Oncor’s active LC&I interconnection queue had 552 requests, which includes approximately 186 gigawatts from data centers and over 19 gigawatts of load from diverse industrial sectors demonstrating broad-based industrial growth within Oncor’s service territory. Of the 570 active generation POI requests in queue at June 30, 2025, approximately 49% were storage, 40% were solar, 7% were wind, and 4% were gas.

Oncor is currently in the process of updating its annual capital plan, including assessing the impact of accelerated timelines for critical transmission infrastructure and system upgrades. The company previously announced a $36.1 billion capital plan for the 2025–2029 period and now anticipates that incremental capital expenditures over that timeframe could exceed $12 billion, particularly in the later years of the plan.

Oncor expects to present an initial view of its new five-year capital plan for 2026–2030 to its Board of Directors in October, with a public announcement of the final updated plan anticipated in the first quarter of 2026.

Legislative Outcomes

The Texas Legislature concluded its regular session on June 2, 2025, with several key legislative outcomes that Oncor believes will positively impact the company and its customers. In particular, Oncor believes Texas House Bill 5247 provides benefits to many of its stakeholders. This bill allows qualifying electric utilities such as Oncor to record costs to a regulatory asset arising from eligible capital investment and apply for interim rate adjustments through an annual UTM filing. The UTM is expected to benefit residential customers by ensuring that new large load customers coming to the Oncor system have costs allocated to them appropriately. The UTM also provides deadlines for the timely completion of PBRP and, by combining six annual filings into one as well as extending the deadline for review by the Public Utility of Commission of Texas (PUCT), should reduce the workload for the PUCT.

Oncor plans to make its first UTM filing in the first half of 2026, after the completion of its rate case. In the meantime, Oncor has begun recognizing revenues associated with qualifying investments for eligible transmission and distribution infrastructure placed in service after December 31, 2024.

The Texas Legislature also passed several new laws and approved significant funding to reduce the risks of wildfires and better prepare the state and local governments to rapidly respond to a wildfire, including a requirement in Texas House Bill 145 that utilities file a wildfire mitigation plan with the PUCT. The PUCT has initiated a rule-making to implement Texas House Bill 145, and Oncor plans to submit its wildfire mitigation plan for approval upon the completion of the PUCT’s rule-making.

Regulatory Update

On June 26, 2025, Oncor filed a comprehensive base rate review request with the PUCT and the 210 cities in its service territory that have retained original jurisdiction over rates to adjust electric delivery rates (PUCT Docket No. 58306). The primary drivers of the rate increase requested in the filing are increased storm restoration expenses, rising material and labor costs, higher insurance premiums, and other inflationary pressures experienced by Oncor since 2021, the historical test year of its last rate review, as well as modifications to support Oncor’s ongoing capital investment program and maintain reliable service amid rapid customer and infrastructure growth. Oncor expects a regulatory decision in the first quarter of 2026. On July 8, 2025, Oncor filed a request for a partial interim adjustment of rates to begin to recover some of the increased costs while the case is pending, subject to refund or surcharge to the extent the interim rates differ from the final rates approved by the PUCT.

Liquidity and Credit Update

As of August 6, 2025, Oncor’s available liquidity totaled approximately $3.9 billion, consisting of cash on hand and available borrowing capacity under its credit facilities, commercial paper programs, and accounts receivable facility. Oncor anticipates these resources, combined with projected cash flows from operations and future financing activities, will be sufficient to meet capital expenditures, maturities of long-term debt, and other operational needs for at least the next twelve months.

On July 29, 2025, S&P Global Ratings (S&P) downgraded Oncor’s issuer credit rating from “A“ to “A-,” citing elevated wildfire risk as a result of changing climate conditions and the absence of liability caps or affirmative legal defenses in Texas. S&P also revised Oncor’s outlook from “negative” to “stable.” In its press release, S&P noted that it expects Oncor’s financial measures to benefit from ratemaking changes implemented under Texas House Bill 5247. S&P also noted that its base case assumes that Oncor receives a constructive rate case order.

Sempra Internet Broadcast Today

(a)

SAIDI is the average number of minutes electric service is interrupted per consumer in a twelve-month period. SAIFI is the average number of electric service interruptions per consumer in a twelve-month period. CAIDI is the average duration in minutes per electric service interruption in a twelve-month period. In each case, our non-storm reliability performance reflects electric service interruptions of one minute or more per customer. Each of these results excludes outages during significant storm events.

(b)

Degree days are measures of how warm or cold it is throughout our service territory. A degree day compares the average of the hourly outdoor temperatures during each day to a 65° Fahrenheit standard temperature. The more extreme the outside temperature, the higher the number of degree days. A high number of degree days generally results in higher levels of energy use for space cooling or heating.

(a)

Distribution base revenues from residential customers are generally based on actual monthly consumption (kWh). On a weather-normalized basis, distribution base revenues from residential customers increased 11.8% in the three months ended June 30, 2025 as compared to the three months ended June 30, 2024 and increased 8.8% in the six months ended June 30, 2025 as compared to the six months ended June 30, 2024.

(b)	Depending on size and annual load factor, distribution base revenues from large commercial & industrial customers are generally based either on actual monthly demand (kilowatts) or the greater of actual monthly demand (kilowatts) or 80% of peak monthly demand during the prior 11 months.

(c)	Includes distribution base revenues from small business customers whose billing is generally based on actual monthly consumption (kWh), lighting sites and other miscellaneous distribution base revenues.

(d)

The 7.7% increase in distribution base revenues in the three months ended June 30, 2025 as compared to the three months ended June 30, 2024 (9.6% increase on a weather-normalized basis) primarily due to incremental interim distribution cost recovery factor (DCRF) rates to reflect increases in invested capital and customer growth; partially offset by lower customer consumption, primarily attributable to milder weather. The 9.3% increase in distribution base revenues in the six months ended June 30, 2025 as compared to the six months ended June 30, 2024 (8.2% increase on a weather-normalized basis) primarily reflects updated interim DCRF rates, increase in customer growth, and increase due to higher customer consumption, primarily attributable to weather.

(e)

Includes revenues recognized in the second quarter of 2025, which were recognized for recoverable UTM eligible transmission and distribution capital investments put into service during the period from January 1, 2025 through June 30, 2025, including depreciation expenses, carrying costs on unrecovered balances and related taxes.
