DALLAS (November 3, 2022) — Oncor Electric Delivery Company LLC (“Oncor”) today reported three months ended September 30, 2022 net income of $318 million compared to net income of $258 million in the three months ended September 30, 2021. Oncor’s quarter-over-quarter net income improvement was driven by increases in revenues from higher customer consumption attributable primarily to significantly warmer weather in the third quarter of 2022 as compared to the third quarter of 2021, updates to base transmission and distribution rates to reflect increases in invested capital, an annual energy efficiency program performance bonus approved in the third quarter of 2022 compared to the prior year’s annual energy efficiency program performance bonus being approved in the fourth quarter of 2021, and customer growth, partially offset by increases in costs associated with additional investments (primarily depreciation, property taxes and borrowing costs) and higher operation and maintenance expense.

“The Oncor team turned in yet another strong financial and operational quarter, focused on meeting the needs of our customers,” said Oncor CEO Allen Nye. “We’re in a very unique time at Oncor. The Oncor service territory, and the entire state of Texas more broadly, is experiencing tremendous – and in many places record – levels of growth. This growth continues despite ongoing supply chain impacts on builders, higher interest rates, and signals

of a national recession. The employees and contractors of Oncor continue to work safely and efficiently to meet the needs of our customers and the ERCOT market. Our work has also included lending a hand to utilities outside of ERCOT after major outages. Recently, Oncor sent more than 500 mutual assistance personnel to Florida to help with power restoration efforts in the wake of Hurricane Ian. I’m so proud of our team and all they do to help power the state of Texas and beyond.”

Oncor’s reported net income of $741 million in the nine months ended September 30, 2022 compared favorably to net income of $595 million in the nine months ended September 30, 2021. Oncor’s period-over-period net income improvement was driven by increases in revenues from updates to base transmission and distribution rates to reflect increases in invested capital, higher customer consumption attributable primarily to significantly warmer weather as compared to the same period in 2021, an annual energy efficiency program performance bonus approved in the third quarter of 2022 compared to the prior year’s annual energy efficiency program performance bonus being approved in the fourth quarter of 2021, and customer growth, partially offset by increases in costs associated with additional investment (primarily depreciation, property taxes and borrowing costs) and higher operation and maintenance expense.

Oncor’s total distribution base revenues in the three months ended September 30, 2022 as compared to the three months ended September 30, 2021 increased 9.2% (2.3% increase on a weather normalized basis). The change in Oncor’s total distribution base revenues in the third quarter of 2022 included a 12.6% increase in distribution base revenues from residential customers (0.7% increase on a weather normalized basis) and a 5.6% increase in distribution base revenues from large commercial and industrial customers. Oncor’s total distribution base revenues in the nine months ended September 30, 2022 as compared to the nine months ended September 30, 2021 increased 10.5% (5.4% increase on a weather normalized basis). The change in Oncor’s total distribution base revenues in the nine months ended September 30, 2022 included a 14.4% increase in distribution base revenues from residential customers (4.5% increase on a weather normalized basis) and a 7.3% increase in distribution base revenues from large commercial and industrial customers. Financial and operational results are provided in Tables A, B, C and D below.

Oncor Service Territory Growth

Oncor’s service territory continues to be one of the fastest growing areas of the country, and Oncor continues to support that growth with new projects, including projects designed to increase reliability for the Electric Reliability Council of Texas, Inc. (“ERCOT”) market.  Oncor connected approximately 14,000 new premises to the ERCOT grid in the third quarter of 2022, as compared to approximately 13,000 in the third quarter of 2021.

At September 30, 2022, Oncor had approximately 565 active transmission point-of-interconnection (“POI”) requests in queue, representing an approximately 52% increase in active POI requests compared to September 30, 2021. Of the active generation requests in queue, approximately 52% are solar, 35% are storage, 10% are

wind and 3% are gas. Through the nine months ended September 30, 2022, Oncor had approximately 230 new POI requests as compared to approximately 160 new POI requests during the same period of 2021. If new requests continue at this pace for the rest of the year, Oncor anticipates it will set a company record for new annual transmission interconnection requests in 2022.

The continued growth across Oncor’s service territory required the construction or upgrading of approximately 300 miles of power lines and included two major substation projects being placed in service in the third quarter of 2022. While the third quarter is generally considered a lighter in-service quarter for transmission projects due to ERCOT summer clearance constraints, Oncor placed $80 million of transmission projects into service in the third quarter of 2022. Also, Oncor expects a significant number of projects to be completed in the fourth quarter of 2022.

Operational Highlights

During the third quarter of 2022, Texas continued to experience significantly higher than normal temperatures. ERCOT’s record peak demand set in June, was broken several times in July reaching a new all-time record peak demand of over 80,000 megawatts on July 20, 2022. Throughout the heat wave experienced in the second and third quarters of 2022, Oncor’s system performed well and Oncor remains on pace to meet its reliability goals for 2022.

In September, Oncor answered the call of mutual assistance partners and deployed more than 500 employees and contractors to Florida as mutual assistance support to Florida utilities, prepositioning personnel and other resources to help restore power in the aftermath of Hurricane Ian.

In early October, an independent third party ESG ratings company improved its rating of Oncor, ranking Oncor in the top 3 percent of electric utilities rated by that agency.

Oncor’s commitment to Diversity, Equity & Inclusion continues to expand. In September 2022, Oncor rolled out an “I Belong” initiative to encourage employees to verify, or update as needed, their demographics. The goal of the initiative is to enable Oncor to enhance its culture and create new initiatives to help ensure that it is supporting all employees.

Capital Expenditure Plans

In the nine months ended September 30, 2022, Oncor’s capital expenditures totaled $2.2 billion and Oncor is on track to meet its $3.0 billion capital plan for 2022. Oncor has and expects to continue to review future capital expenditure plans with its board of directors. However, given the number of uncertainties at this stage in the capital expenditure planning process, particularly continued record growth in Texas, high inflation and a pending rate case, Oncor management recommended that its board of directors delay approval of a 2023 capital expenditure budget until a future board meeting. As a result, Oncor will not be updating its future capital plans at this time, but expects to announce a new five-year capital plan by the end of the first quarter of 2023.

Base Rate Review

Oncor’s base rate case before the Public Utility Commission of Texas (“PUCT”) continues to progress. The rate review includes a request for an average annual revenue requirement increase over current adjusted rates of 4.5%, and, if approved as requested, would result in an aggregate annual revenue requirement increase of approximately $251 million. The rate review also requests a revised regulatory capital structure ratio of 55% debt to 45% equity and an authorized return on equity of 10.3%. Oncor’s current authorized regulatory capital structure ratio is 57.5% debt to 42.5% equity and its current authorized return on equity is 9.8%. A hearing on the merits was held before the State Office of Administrative Hearings from September 26, 2022 to October 4, 2022, and a proposal for decision is expected from the administrative law judges to the PUCT for its consideration by December 27, 2022. Resolution of the rate review requires issuance of a final order by the PUCT, which is expected by the end of the first quarter of 2023, and new rates would go into effect following issuance of that order.

Liquidity

As of November 3, 2022, Oncor’s available liquidity, consisting of cash on hand and available credit facility and commercial paper program capacity, totaled approximately $2.2 billion. Oncor expects cash flows from operations combined with long-term debt issuances and term loan credit agreements as well as availability under its credit facility and commercial paper program to be sufficient to fund current obligations, projected working capital requirements, maturities of long-term debt and capital expenditures for at least the next 12 months.
