ONCOR REPORTS FIRST QUARTER 2026 RESULTS

DALLAS, May 7, 2026 /PRNewswire/ -- Oncor Electric Delivery Company LLC ("Oncor") today reported net income of $212 million for the three months ended March 31, 2026, compared to net income of $181 million in the three months ended March 31, 2025. The increase in net income of $31 million was driven by overall higher revenues primarily attributable to an increase in revenues recognized related to the Unified Tracker Mechanism ("UTM") and the System Resiliency Plan ("SRP"), updated interim rates to reflect increases in invested capital, and customer growth, partially offset by lower customer consumption, primarily attributable to milder weather, 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.

"We remain focused on meeting the needs of our customers as we execute our capital plan, which supports the continued expansion of Texas. Constructive legislative and regulatory frameworks are helping enable these investments, and we look forward to continuing our work with customers and stakeholders as we invest in the safe, reliable, and affordable electric service our growing state depends on. This is an important time in the history of our company, and I am proud of our team's commitment to meeting this moment," said Oncor CEO Allen Nye. "I also want to thank our employees and contractors for the continued work that is underway to prepare our system for the spring storm season and another Texas summer."

Operational Highlights
In 2026, Oncor is executing a capital expenditure budget of approximately $9.0 billion, representing an increase of roughly 25% compared to its actual capital expenditures in 2025, as the company continues to respond to sustained load growth and expanding system needs. In the first quarter of 2026, Oncor built, rebuilt, or upgraded nearly 700 circuit miles of transmission and distribution lines and increased its premise count by approximately 13,400, reflecting ongoing population and business growth in Texas. Active transmission point-of-interconnection ("POI") requests increased 19% year over year. As of May 6, 2026, Oncor held approximately $4.0 billion in customer collateral for active generation and Large Commercial and Industrial ("LC&I") transmission POI requests. This collateral is intended to reduce the risk of rate payers bearing costs for projects that are cancelled after Oncor has expended funds toward building the infrastructure.

As of March 31, 2026, Oncor had 565 active generation POI requests in queue, composed of approximately 47% storage, 40% solar, 8% wind, and 5% gas. In addition, Oncor's active transmission LC&I interconnection queue included 697 requests at the end of the first quarter of 2026. Those requests included approximately 271 gigawatts from data centers and over 18 gigawatts of load from various other industrial sectors, demonstrating broad-based industrial growth within Oncor's service territory.

On April 1, 2026, Oncor submitted 122 gigawatts of large load forecast data and 5.2 gigawatts of medium load forecast data through 2036 for inclusion in the Electric Reliability Council of Texas' ("ERCOT") 2026 Regional Transmission Plan ("RTP"). Oncor is also deeply engaged with ERCOT stakeholders around the development of a batch study process to review transmission capacity needs for large load interconnections. In addition, Oncor continues to advance significant transmission projects necessary to serve new large loads through the ERCOT Regional Planning Group process. For example, on April 20, 2026, the ERCOT board of directors endorsed transmission upgrades for the south Dallas – Fort Worth ("DFW") region to enable approximately 4 gigawatts of new load and address other reliability issues. Oncor expects to be responsible for a majority of these DFW projects, which have anticipated in-service dates between 2026 and 2032.

Progress on the Permian Basin Reliability Plan ("PBRP") remains on track, with consistent advancement toward targeted in-service dates through 2030. Coordination with suppliers, ERCOT, and other industry stakeholders is ongoing. Oncor has now submitted approximately two-thirds of the total Certificates of Convenience and Necessity ("CCN") applications required for its PBRP projects, including all CCNs required for Oncor's 765 kV PBRP import path projects. Construction is underway on PBRP local projects, with two already complete. Construction of the 765 kV PBRP import transmission infrastructure is planned to begin in the second quarter of 2026 with the grading of a 765 kV switching station. In addition to the PBRP, construction continues on other Permian Basin-area projects.

Regulatory Update
On April 17, 2026, the Public Utility Commission of Texas ("PUCT") issued an order resolving Oncor's comprehensive base rate review proceeding in PUCT Docket No. 58306. The order, which approved an unopposed settlement agreement among the parties, provides for:

• An increase of approximately $560 million over Oncor's 2024 test year adjusted annualized revenues (an increase of approximately 8.7%);
• A regulatory capital structure ratio of 56.5% debt to 43.5% equity;
• An authorized return on equity of 9.75%, and a 4.94% authorized cost of debt.

Oncor estimates the approved rates will result in an increase to residential customer bills of approximately 3% per month based on 1,000 kWh/month usage at an average retail electric price of $0.15/kWh. The order provides for new rates to take effect on June 1, 2026.

Under a prior interim rates agreement, Oncor's existing rates became interim rates for the period from January 1, 2026 through the implementation date of the new rates. Oncor is permitted to surcharge the difference between the new rates and the interim rates. Oncor anticipates filing that surcharge request in June, shortly after the effective date of the new billing rates. Oncor will begin recognizing accounting impacts of the base rate order in the second quarter of 2026. Oncor currently estimates that the effects of incremental revenues and expenses from the PUCT order related to the first quarter of 2026, when recognized, will increase second quarter 2026 earnings by approximately $70 million.

On April 22, 2026 Oncor made its distribution and transmission tracker filings under the new UTM process with the PUCT, requesting an interim rate update to reflect approximately $4.4 billion in eligible transmission and distribution net capital investment costs incurred from January 1, 2025 to December 31, 2025. If approved as requested, we expect the application would result in a net revenue increase of approximately $550 million. The UTM also updates customer allocations to reflect continued growth among LC&I customers. Oncor estimates the request would result in an average monthly increase of approximately $3.85 over current rates for a residential customer using 1,000 kWh of electricity per month at an average retail electric price of $0.15/kWh, an approximate 2.5% increase. Oncor anticipates a final order and updated rates in the second half of 2026.

During the first quarter, Oncor filed seven new CCN applications for needed transmission projects, including PBRP CCN applications, and received regulatory approval of three previously filed CCN applications, continuing the momentum of efficient and timely regulatory approvals.

Liquidity and Credit Update
As of May 6, 2026, Oncor's available liquidity totaled approximately $3.3 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.

Positive regulatory and legislative outcomes in Texas have continued to support Oncor's credit metrics. Moody's Investors Service, Inc. recently revised its credit ratings outlook for Oncor from negative to stable.
