PART I

Items 1. and 2. BUSINESS AND PROPERTIES

References in this report to “we,” “our,” “us” and “the company” are to Oncor and/or its subsidiaries as apparent in the context. See “Glossary” starting on page 4 for the definition of terms and abbreviations.

Overview of Oncor

We are a regulated electricity transmission and distribution company that provides the essential service of delivering electricity safely, reliably and economically to end-use consumers through our electrical systems, as well as providing transmission grid connections to merchant generation facilities and interconnections to other transmission grids in Texas. We are a direct, majority-owned subsidiary of Oncor Holdings, which is indirectly and wholly owned by Sempra. Oncor Holdings owns 80.25% of our membership interests and Texas Transmission owns 19.75% of our membership interests. Since 2007, various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with ownership interests in Oncor or Oncor Holdings. See “—Ring Fencing Measures” below for a discussion of those measures. We are a limited liability company organized under the laws of the State of Delaware, formed in 2007 as the successor entity to Oncor Electric Delivery Company, a corporation formed under the laws of the State of Texas in 2001.

The company is managed as an integrated business; consequently, there is only one reportable segment.

We operate the largest transmission and distribution system in Texas, delivering electricity to nearly 4.0 million homes and businesses and operating more than 143,000 circuit miles of transmission and distribution lines at December 31, 2023.

We provide:

wholesale transmission services to our electricity distribution business, as well as to non-affiliated electricity distribution companies, electric cooperatives and municipally-owned utilities, and

distribution services, consisting of retail delivery services to REPs that sell electricity to end-use customers, as well as wholesale delivery services to electric cooperatives and municipally-owned utilities.

Our transmission and distribution rates are regulated by the PUCT and certain cities, and in certain limited instances, by the FERC. We are not a seller of electricity, nor do we purchase electricity for resale. The majority of consumers of the electricity we deliver through our distribution business are free to choose their electricity supplier from REPs who compete for their business.

Our transmission and distribution assets are located principally in the north-central, eastern, western and panhandle regions of Texas, in over 120 counties and more than 400 incorporated municipalities. We deliver electricity across a distribution service territory that has an estimated population of approximately 13 million, including the cities of Dallas and Fort Worth and the surrounding suburbs, as well as Waco, Wichita Falls, Odessa, Midland, Tyler, Temple, Killeen and Round Rock, among others.

Our website address is www.oncor.com. The information on our website or available by hyperlink from the website shall not be deemed a part of, or incorporated by reference into, this Annual Report on Form 10-K.

Ring-Fencing Measures

Since 2007, various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with ownership interests in Oncor or Oncor Holdings. These ring-fencing measures serve to mitigate the Oncor Ring-Fenced Entities’ credit exposure to Sempra and its affiliates and any other direct or indirect owners of Oncor and Oncor Holdings, and to reduce the risk that the assets and liabilities of the Oncor Ring-Fenced Entities would be substantively consolidated with the assets and liabilities of any Sempra entity or any other direct or indirect owners of Oncor and Oncor Holdings in connection with a bankruptcy of any such entities. These measures include the November 2008 sale of 19.75% of Oncor’s equity interests to Texas Transmission.

7

In March 2018, Sempra indirectly acquired Oncor Holdings in the Sempra Acquisition. That transaction was approved by the PUCT in the Sempra Order, which order outlines certain ring-fencing measures, governance mechanisms and restrictions that apply to Oncor Holdings and Oncor after the Sempra Acquisition. As a result of these ring-fencing measures, Sempra does not control Oncor, and the ring-fencing measures limit Sempra’s ability to direct the management, policies and operations of Oncor, including the deployment or disposition of Oncor’s assets, declarations of dividends, strategic planning and other important corporate issues and actions. Our LLC Agreement requires PUCT approval of certain revisions to the agreement, including, among other things, revisions to our governance structure and other various ring-fencing measures.

None of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or obligations of any Sempra entity or any other direct or indirect owner of Oncor or Oncor Holdings. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of any Sempra entities and any other direct or indirect owner of Oncor or Oncor Holdings. We do not bear any liability for debt or contractual obligations of Sempra and its affiliates or any other direct or indirect owner of Oncor or Oncor Holdings, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from Sempra and its affiliates and any other direct or indirect owner of Oncor or Oncor Holdings.

Oncor is a limited liability company governed by a board of directors, not its members. The Sempra Order and our LLC Agreement require that the board of directors of Oncor consist of thirteen members, constituted as follows:

seven Disinterested Directors, who (i) shall be independent directors in all material respects under the rules of the New York Stock Exchange in relation to Sempra or its subsidiaries and affiliated entities and any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, and (ii) shall have no material relationship with Sempra or its subsidiaries or affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, currently or within the previous ten years;

two members designated by Sempra (through Oncor Holdings);

two members designated by Texas Transmission; and

two current or former officers of Oncor (each, an Oncor Officer Director).

Until March 9, 2028, in order for a current or former officer of Oncor to be eligible to serve as an Oncor Officer Director, the officer cannot have worked for Sempra or any of its subsidiaries or affiliated entities (excluding Oncor Holdings and Oncor) or any other entity with a direct or indirect ownership interest in Oncor or Oncor Holdings in the ten-year period prior to the date on which the officer first became employed by Oncor. Oncor Holdings, at the direction of STIH, has the right to nominate and/or seek the removal of the Oncor Officer Directors, subject to approval by a majority of the Oncor board of directors.

In addition, the Sempra Order provides that Oncor’s board of directors cannot be overruled by the board of directors of Sempra or any of its subsidiaries on dividend policy, the issuance of dividends or other distributions (except for contractual tax payments), debt issuance, capital expenditures, operation and maintenance expenditures, management and service fees, and appointment or removal of members of the board of directors, provided that certain actions may also require the additional approval of the Oncor Holdings board of directors. The Sempra Order also provides that any changes to the size, composition, structure or rights of the board of directors must first be approved by the PUCT. In addition, if Sempra acquires Texas Transmission’s interest in Oncor, the two board of director positions on Oncor’s board of directors that Texas Transmission is entitled to appoint will be eliminated and the size of Oncor’s board of directors will be reduced by two.

Additional regulatory commitments, governance mechanisms and restrictions provided in the Sempra Order and our LLC Agreement to ring-fence Oncor from its owners include, among others:

A majority of the Disinterested Directors of Oncor and the directors designated by Texas Transmission that are present and voting (of which at least one must be present and voting) must approve any annual or multi-year budget if the aggregate amount of capital expenditures or operation and maintenance expenditures in such budget is more than a 10% increase or decrease from the corresponding amounts of such expenditures in the budget for the preceding fiscal year or multi-year period, as applicable;

Oncor may not pay any dividends or make any other distributions (except for contractual tax payments) if a majority of its Disinterested Directors or either of the two directors appointed by Texas Transmission determines that it is in the best interests of Oncor to retain such amounts to meet expected future requirements;

8

At all times, Oncor will remain in compliance with the debt-to-equity ratio established by the PUCT from time to time for ratemaking purposes, and Oncor will not pay dividends or other distributions (except for contractual tax payments) if such payment would cause its debt-to-equity ratio to exceed the debt-to-equity ratio approved by the PUCT;

If the credit rating on Oncor’s senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), Oncor will suspend dividends and other distributions (except for contractual tax payments), unless otherwise allowed by the PUCT;

Without the prior approval of the PUCT, neither Sempra nor any of its affiliates (excluding Oncor) will incur, guaranty or pledge assets in respect of any indebtedness that is dependent on the revenues of Oncor in more than a proportionate degree than the other revenues of Sempra or on the membership interests of Oncor, and there will be no debt at STH or STIH at any time following the closing of the Sempra Acquisition;

Neither Oncor nor Oncor Holdings will lend money to, borrow money from, or share credit facilities with, Sempra or any of its affiliates (other than Oncor subsidiaries), or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings; and

There must be maintained certain “separateness measures” that reinforce the legal and financial separation of Oncor from its owners, including a requirement that dealings between Oncor, Oncor Holdings and their subsidiaries with Sempra, any of Sempra’s other affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, must be on an arm’s-length basis, limitations on affiliate transactions, separate recordkeeping requirements and a prohibition on Sempra or its affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings pledging Oncor assets or membership interests for any entity other than Oncor.

Oncor’s Market (ERCOT statistics below were derived from information published by ERCOT and/or the PUCT)

We are a member utility and operate within the ERCOT market. This market represents approximately 90% of the electricity consumption in Texas. ERCOT is the regional reliability coordinating organization for member electricity systems in Texas and the Independent System Operator (ISO) of the interconnected transmission grid for those systems. ERCOT is subject to oversight by the PUCT and the Texas Legislature. ERCOT is responsible for ensuring reliability, adequacy and security of the electric systems, as well as nondiscriminatory access to transmission service by all wholesale market participants in the ERCOT region. ERCOT’s membership consists of corporate and associate members, including electric cooperatives, municipal power agencies, independent generators, independent power marketers, transmission service providers, distribution services providers, independent REPs and consumers.

Wholesale transactions within the ERCOT market are generally not subject to regulation by the FERC. The ERCOT market has limited interconnections to other markets in the U.S. and Mexico, which limits potential electricity imports into and exports out of the ERCOT market.

The ERCOT market operates under reliability standards set by NERC. The PUCT has primary jurisdiction over the ERCOT market to ensure the adequacy and reliability of power supply across Texas’ main interconnected transmission grid. We, along with other owners of transmission and distribution facilities in Texas, assist the ERCOT ISO in its operations. We have planning, design, construction, operation and maintenance responsibility for the portion of the transmission grid and the load-serving substations we own, primarily within our certificated distribution service area. We participate with the ERCOT ISO and other ERCOT utilities in obtaining regulatory approvals and planning, designing, constructing and upgrading transmission lines in order to remove existing constraints and interconnect generation on the ERCOT transmission grid. The transmission line projects are necessary to meet reliability needs, support energy production and increase bulk power transfer capability.

In August 2023, ERCOT recorded a historical peak hourly demand of 85,508 MW, reflecting a 6.7% (5,360 MW) increase over the previous year’s historical peak hourly demand recorded in July 2022.

Oncor’s Strategies

We focus on delivering electricity in a safe, reliable, and cost-effective manner, minimizing service interruptions, investing in our transmission and distribution infrastructure to maintain our system, serving our customers with a modernized grid, providing interconnections to other transmission systems in Texas, and supporting energy production through transmission grid connections to merchant generation facilities.

9

Our organic growth strategies include constructing transmission and distribution facilities and investing in reliability measures and technology upgrades to support the needs of our growing customer base, the state of Texas, and the ERCOT market. Our five-year capital plan reflects significant expected investments and growth, and the majority of our capital investments are anticipated to be eligible for recovery in rates through interim TCOS rate adjustments or interim DCRF rate adjustments, which we refer to as capital trackers. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Relating to Future Earnings and Results of Operations—Revenue, Rate Regulation and Cost Recovery” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition—Liquidity and Capital Resources” for more information on our historical and projected capital expenditures and our cost recovery mechanisms for capital investments.

We emphasize operating in a cost-effective manner, and we believe that building upon opportunities to scale capital projects across our existing infrastructure enables us to create value by minimizing duplicative costs, creating efficiencies of scale, managing supply costs more efficiently, and building and standardizing distinctive process expertise.

We also believe there are opportunities for growth arising from customer efforts to decrease their respective carbon footprints through electrification efforts in the ERCOT market. Increased electrification efforts in the ERCOT market, particularly through oil and gas producers electrifying their operations and continued adoption of electric vehicles, could result in further increased demand within the ERCOT system. In addition, we believe demand in ERCOT could be significantly increased as a result of large load customers utilizing growing computing power needs related to cryptocurrency mining, artificial intelligence technology, data storage and other technological needs and advances. Such increased demand could result in higher electricity volumes delivered by us as well as obligations for additional capital investments to interconnect sources to the ERCOT grid and meet service reliability needs. Legislation and regulation to combat climate change could also have an impact on operations and demand in the ERCOT market that require additional capital investments by us or impact electricity volumes delivered. For instance, the Inflation Reduction Act of 2022 contains provisions designed to encourage renewable energy production, which could incentivize construction of additional renewable energy capacity in Texas. Such additional renewable energy capacity could in turn require new capital construction projects from us to connect those generation sources to the ERCOT grid. In addition to organic growth strategies, we also regularly evaluate opportunities to make selective strategic acquisitions involving regulated assets.

Oncor’s Operations

Electricity Transmission — Our electricity transmission business is responsible for the safe and reliable operations of our transmission network and substations. These responsibilities consist of the construction, operation, maintenance, and security of transmission facilities and substations and the monitoring, controlling and dispatching of high-voltage electricity over our transmission facilities in coordination with ERCOT.

As an ERCOT member utility, our transmission business, with applicable regulatory approval, also participates with ERCOT and other member utilities to plan, design, construct and operate new transmission lines to maintain reliability, interconnect to merchant generation facilities, increase bulk power transfer capability and/or minimize limitations and constraints on the ERCOT transmission grid.

Transmission revenues, also known as TCOS revenues or network transmission revenues, are provided under tariffs approved by either the PUCT or, to a small degree related to limited interconnections to other markets, the FERC. Network transmission revenues compensate us for delivery of electricity over our transmission facilities operating at 60kV and above and are collected from load serving entities benefitting from our transmission system. Other services we offer through our transmission business that we classify as other miscellaneous revenues include system impact studies, facilities studies, transformation service and maintenance of transformer equipment, substations and transmission lines owned by other parties.

PUCT rules allow us to file up to two interim TCOS rate adjustment applications in a calendar year to reflect changes in our invested transmission capital. This interim TCOS rate adjustment is a capital tracker provision that encourages investment in the transmission system to help ensure reliability and efficiency by helping to shorten the time period between a utility’s investment in transmission infrastructure and its ability to start recovering and earning a return on such investments. All investments included in a capital tracker are ultimately subject to prudence review by the PUCT in the next base rate review after such assets are put into service. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for more information on interim TCOS rate adjustment applications.

3,969,000 approximate number of points of delivery, an increase of approximately 73,000 over the number of points of delivery at December 31, 2022, and

1.92% average growth per year over the past five years in the number of distribution system points of delivery we serve, excluding lighting sites.

In general, distribution revenues from residential and small business users are based on actual monthly consumption (kWh), and, depending on size and annual load factor, revenues from large commercial and industrial users are based either on actual monthly demand (kilowatts) or the greater of actual monthly demand (kilowatts) or 80% of peak monthly demand during the prior eleven months.

PUCT rules allow utilities to file, under certain circumstances, interim DCRF rate adjustment applications to recover distribution investments. In June 2023, legislation was enacted by the Texas Legislature that increased the number of interim DCRF rate adjustment applications that may be filed by utilities in a year from one application to up to two applications per year. As with interim TCOS rate adjustments, interim DCRF rate adjustments are a capital tracker, with all investments included in the capital tracker ultimately subject to prudence review by the PUCT in the next base rate review

11

after such assets are put into service. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations” for more information on interim DCRF rate adjustment applications.

Properties — Most of our power lines have been constructed over lands of others pursuant to easements or along public highways, streets and rights-of-way pursuant to permits, public utility easements, franchise or other agreements or as otherwise permitted by law. In addition to power lines and related assets in our transmission and distribution system, we also own or lease land, offices, facilities, equipment, and vehicles to operate our business. Certain of our transmission and distribution assets, including certain real property assets, are subject to a first priority lien pursuant to our Deed of Trust. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition—Liquidity and Capital Resources” for more information on our Deed of Trust.

Customers — Our transmission business customers consist of municipally-owned utilities, electric cooperatives and other distribution companies. At December 31, 2023, our distribution business customers primarily consisted of over 100 REPs that sell electricity we distribute to consumers in our certificated service area. Revenues from REP subsidiaries of Vistra and NRG Energy, Inc., our two largest customers, collectively represented 25% and 23%, respectively, of our total operating revenues for the year ended December 31, 2023, 26% and 24%, respectively, of our total operating revenues for the year ended December 31, 2022 and 25% and 23%, respectively, of our total operating revenues for the year ended December 31, 2021. No other customer represented more than 10% of our total operating revenues during such periods. The majority of consumers of the electricity we deliver through our distribution business are free to choose their electricity supplier from REPs who compete for their business.

Competition — Oncor operates in certificated areas designated by the PUCT. The majority of Oncor’s service territory is singularly certificated, with Oncor as the sole certificated transmission and distribution provider. However, in multi-certificated areas of Texas, Oncor competes with certain municipal utilities and electric cooperatives for the right to serve end-use customers. In addition, the electric industry is undergoing rapid technological change, and third-party DER and virtual power plants and other technologies may increasingly compete with our traditional transmission and distribution infrastructure for meeting customers’ electricity needs. See “Item 1A. Risk Factors—The growth of DER and similar technologies or actions that decrease demand or consumption of electricity delivered by us may significantly adversely impact our business, including by limiting future infrastructure investments and reducing our ability to timely recover the cost of our investment in, and earn a reasonable return on, our electricity delivery facilities.”

Seasonality — Our revenues and results of operations are subject to seasonality, weather conditions and other electricity usage drivers, with distribution revenues being highest in the summer.

Regulation and Rates — As our operations are wholly within Texas, we believe we are not a public utility as defined in the Federal Power Act and, as a result, are generally not subject to FERC regulation under the act. However, we are subject to reliability standards adopted and enforced by Texas RE and NERC (including critical infrastructure protection) under the Federal Power Act.

The PUCT has original jurisdiction over wholesale transmission rates and services and retail rates and services in unincorporated areas and in those municipalities that have ceded original jurisdiction to the PUCT and has exclusive appellate jurisdiction to review the retail rates, retail services, and ordinances of municipalities. Generally, PURA prohibits the collection of any rates or charges by a public utility (as defined by PURA) that does not have the prior approval of the appropriate regulatory authority (i.e., the PUCT or the municipality with original jurisdiction).

At the state level, PURA requires utility owners or operators of transmission facilities to provide open-access wholesale transmission services to third parties at rates and terms that are nondiscriminatory and comparable to the rates and terms of the utility’s own use of its system. The PUCT has adopted rules implementing the state open-access requirements for all utilities, including us, that are subject to the PUCT’s jurisdiction over transmission services.

As a regulated utility, our business is subject to extensive governmental regulations and compliance obligations, which could greatly impact our business. See “Item 1A. Risk Factors—Our business is subject to ongoing complex governmental regulations and legislation that have impacted, and will continue in the future to impact, our business and results of operations” and “Item 1A. Risk Factors—We are subject to various mandatory regulatory standards and requirements, including with respect to service quality, reliability, and weatherization of facilities. Efforts to comply with those standards could subject us to higher operating costs and/or increased capital expenditures, and non-compliance with applicable standards or expectations could have a material adverse effect on our business.” as well as “Item 7.

12

Management’s Discussion and Analysis of Financial Condition and Results of Operations” and Notes 2 and 7 to Financial Statements for a discussion of certain regulatory matters and commitments and the material effects of compliance with regulations on our business.

Investing in Infrastructure — In 2023, we invested approximately $3.8 billion in our transmission and distribution system to upgrade the transmission system and associated facilities, to extend the distribution infrastructure and to pursue certain initiatives in infrastructure, including investments to support system growth, reliability and resiliency. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition—Liquidity and Capital Resources” for more information on our capital expenditures, including our projected capital expenditures for the next five years.

Environmental Regulations and Related Considerations — The TCEQ and the EPA have jurisdiction over water discharges (including storm water) from facilities in Texas. We believe our facilities are presently in material compliance with applicable state and federal requirements relating to water discharges. We believe we hold all required wastewater discharge permits from the TCEQ for facilities in operation and have applied for or obtained necessary permits for facilities under construction. We also believe we can satisfy the requirements necessary to obtain any required permits or renewals. There are also federal rules pertaining to Spill Prevention, Control and Countermeasure (SPCC) plans for oil-filled electrical equipment and bulk storage facilities for oil that affect certain of our facilities. We have implemented SPCC plans as required for those substations, work centers and distribution systems, and believe we are currently in material compliance with these rules.

Treatment, storage and disposal of solid waste and hazardous waste are regulated at the state level under the Texas Solid Waste Disposal Act and at the federal level under the Resource Conservation and Recovery Act of 1976, as amended, and the Toxic Substances Control Act. The EPA has issued regulations under the Resource Conservation and Recovery Act of 1976, as amended, and the Toxic Substances Control Act, and the TCEQ has issued regulations under the Texas Solid Waste Disposal Act applicable to our facilities. We are in material compliance with applicable solid and hazardous waste regulations.

Our capital expenditures for environmental matters totaled $80 million in 2023 and are expected to total approximately $101 million in 2024.

Human Capital Management — At December 31, 2023, we had 4,774 employees, including 819 employees covered under a collective bargaining agreement that expires in October 2026. As of December 31, 2023, the average length of service among all employees was 12.7 years, and over 99% of our employees were employed on a full-time basis. In addition, at December 31, 2023, we had 60 interns serving in full-time or part-time internships.

Attracting, retaining, and developing high quality talent is key to our human capital management strategy. We employ a multi-faceted recruiting strategy to recruit a diverse, high quality talent pool, including leveraging several higher education and high school partnerships established across our service territory and helping higher education and technical institutions develop linemen schools and courses. In 2023, we implemented a mentorship program designed to help retain, develop and mentor employees who participate in our employee resource groups (ERGs). Our ERGs are voluntary, employee-led networks open to all employees. We also believe market-competitive compensation and benefits packages are necessary to attract and retain talent, and we annually conduct a market assessment using third party benchmark salary and benefit data to determine the competitiveness of our compensation and benefit programs against utility/energy services companies and general industry companies. We also continuously monitor the competitive labor market and macroeconomic conditions with a view toward adjusting compensation and benefit practices as needed in advance of the annual market assessment to attract, develop, and retain talent. We strive to provide competitive packages that include performance-based compensation that rewards organizational achievement as well as individual efforts. Oncor’s benefits package includes, among other things, retirement savings plans, paid vacation time, and parental leave. Oncor also offers employees the ability to participate in benefit plans for medical, dental and vision insurance, health savings and spending accounts, group term life insurance and accidental death and disability insurance, as well as certain other health and welfare benefits. The physical and mental health of our workforce are also priorities, and as such, we hosted various mental health awareness programming and activities in 2023 and updated our vacation policy effective January 1, 2023 to provide additional vacation time to regular, full-time employees. For the year ended December 31, 2023, we experienced an annual employee turnover rate of approximately 6.1%, including approximately 2.1% that was attributable to retirements.

13

Our workplace culture is central to our efforts to attract, retain, and develop talent. We strive to create a workplace culture that emphasizes the following key areas:

Safety — Safety is a key priority of the company and our human capital management strategy. Employees are regularly educated and trained on safety issues and receive regular safety communications, particularly in field locations. We have established an annual safety plan, which outlines our yearly safety programs and initiatives. In January 2023, we hosted a two-day safety conference for our transmission and distribution employees which included presentations by our senior management, covered a variety of safety topics, and outlined our safety priorities, initiatives, and expectations for the upcoming year. Our safety procedures are continually improving and adapting to the ever-changing events that our workforce encounters. Employees are encouraged to propose improvements to our safety procedures and are recognized for their innovations and contributions to safety improvements. For example, during the hotter than normal temperatures experienced in the summer of 2023, our safety teams proactively implemented measures to keep our workforce sufficiently hydrated in order to minimize heat stroke exposure and other heat-related health concerns. We regularly track our safety performance and benchmark it against industry peers, and achievement of significant safety milestones are recognized and celebrated. In addition, a safety performance metric is included in our annual and long-term incentive programs to further promote safety among employees. As a company, we’ve further committed to the importance of safety by including a safety-related performance metric in the $2B Credit Facility.

Ethical Conduct — Ethical conduct is a core value of the company, and every employee is required to complete code of conduct training upon joining Oncor and annually thereafter. We also maintain an ethics and compliance hotline monitored by an independent, third-party service, where employees may anonymously report any suspected unethical behavior or policy violations. Our compliance leadership team meets quarterly to review employee code of conduct compliance-related matters, and the company’s code of conduct compliance program and activities are reviewed with the audit committee of our board of directors (the Audit Committee) on at least an annual basis.

Collaboration and Innovation — Our company-wide “One Oncor” initiative emphasizes cross-functional collaboration, particularly to spur innovation. An innovation and improvement council, made up of management-level employees, focuses on enhancing innovation and continuous improvement throughout the company. We have also instituted an innovation and continuous improvement initiative, Power On Deliver Strong, and developed a framework based on Lean Six Sigma that enables and encourages employees to identify and execute improvement opportunities to our services, business processes, and systems, including an annual internal Innovation Week campaign. In addition, we offer various training opportunities to employees to encourage innovation, and maintain a portal for all employees to submit innovation and improvement ideas and success stories. All employees are also required to complete continuous improvement training.

Diversity, Equity, and Inclusion — We are committed to maintaining a culture of diversity, equity, and inclusion (DEI), and fostering an environment that gives each employee a sense of belonging and inclusion to achieve their full potential. Our Vice President of Diversity, Equity & Inclusion and officer-level steering committee for DEI have instituted and supported various initiatives to promote this effort across the company. Our employees may participate in one or more of our eight ERGs. ERGs focus on leveraging diverse perspectives of our workforce, increasing networking and professional development opportunities for our employees, while strengthening our business culture of inclusion and belonging. ERG participation continues to grow across the company, with approximately 20% of employees participating in at least one employee resource group as of December 31, 2023 as compared to 17% as of December 31, 2022.

Healthy Lifestyles — We have established various health and wellness initiatives to encourage employees to adopt healthy living habits, including an incentive program that promotes exercise, healthy eating, and healthy lifestyles. Our health and wellness programs focus on physical, financial, and mental health, and we offer employees various resources to enhance their overall well-being, including an employee assistance program that offers mental and behavioral health resources. We also maintain programs that fund Oncor employee participation in eligible community non-profit fitness events, including community non-profit fitness events across our service territory.

Community Involvement — We promote various community initiatives and non-profit partnerships and encourage employee volunteerism and participation in community events, including grants supporting eligible non-profits for which employees provide volunteer hours. These volunteer councils identify local community organizations and causes to support and coordinate volunteer opportunities and fundraisers to benefit those nonprofits and causes. In addition, we maintain a 501(c)(3) private foundation, the Oncor Cares Foundation, to help expand our charitable giving and support for the many communities where we work and live.

Employee Engagement — How engaged our workforce is and how committed our employees are to their work and the company are important to Oncor. We recognize that the more engaged employees are, the more

14

productive they are and the more likely they are to remain with the company. As a result of our annual company-wide employee engagement survey, we continued to initiate various efforts in 2023 to enhance employee engagement at both the local and corporate levels, including manager and supervisor trainings on the survey results. We conducted our third annual company-wide employee engagement survey in late 2023, which indicated an increase in the number of engaged employees versus prior year results, and are using the results of that survey to continue to develop and implement our employee engagement strategy.

Talent Development — We maintain various leadership and workforce training and development programs to engage employees and promote continued professional growth. In addition, our board of directors annually reviews our talent management strategy, including talent development programs, and our executive officer talent pipeline. Our executive officers also conduct regular ongoing succession planning with respect to other members of management. In addition, we are actively focused on attracting and developing employees at all levels to replace employees likely to retire in the next few years.

Item 1A. RISK FACTORS

Risks Related to Regulatory and Legislative Matters

Our business is subject to ongoing complex governmental regulations and legislation that have impacted, and will continue in the future to impact, our business and results of operations.

As a regulated electricity transmission and distribution company, our business is subject to numerous local, state, and federal laws (including PURA, certain provisions of the Federal Power Act, the Public Utility Regulatory Policies Act of 1978, the Energy Policy Act of 2005, the Code and ERISA), executive orders issued by the President of the U.S. and the Governor of Texas, governmental policies, regulations, and administrative actions by the PUCT and other governmental authorities (including NERC, Texas RE, the TCEQ, the FERC, the EPA, and the SEC). As an ERCOT member utility, we are also subject to ERCOT rules, guidelines, directives, and protocols for transmission and distribution utilities operating in ERCOT. We must continually adapt to any new or revised or reinterpreted laws, policies, regulations, rules, guidelines, directives, and protocols and administrative actions, any of which could expose us to increased costs, expenses, and employee time and effort needed to comply, and have a material and adverse effect on our business, cash flows, liquidity, financial condition, results of operations and/or business prospects.

In addition, if it is determined that we did not comply with applicable laws, statutes, regulations, rules, directives, tariffs or orders and we are ordered to pay a material amount in penalties, customer/rate payer refunds, or other amounts, our financial condition, results of operations, cash flows and our reputation could be materially and adversely affected. For example, under the Energy Policy Act of 2005, the FERC can impose penalties (up to $1 million per day per violation) for failure to comply with mandatory electric reliability standards, including standards to protect the power system against potential disruptions from cyber and physical security breaches. In addition, the PUCT may impose penalties on us if it finds that we violated PURA or any PUCT rule or order adopted under PURA. The PUCT has the authority to impose penalties of up to $1 million per day for failure to meet certain weatherization requirements and up to $25,000 per day per violation for other violations.

Negative public perception of us or our industry could also result in laws, regulations, governmental/regulatory investigations, and administrative actions that could have a material adverse effect on us. The Texas Legislature operates under a biennial system and meets in regular session in every odd-numbered year and during special sessions called by the Governor of Texas. During any regular or special session, the Texas Legislature may hold hearings relevant to our business and bills may be introduced that, if adopted, could materially and adversely affect our business and our business prospects. In 2023, the Texas Legislature passed various legislation impacting the electric industry that could have a significant impact on our business, financial condition, and results of operations. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Regulation and Rates—State Legislation” for more information on this legislation. However, there can be no assurance that any anticipated impacts of such legislation will be at, or near, the levels anticipated by management, or realized at all, or in the anticipated timeframes.

Our business is subject to rate regulation, and the regulatory review process could materially adversely impact our financial condition, cash flows, and results of operations, including by limiting our ability to fully recover costs, reducing the rate we earn on invested capital, or negatively impacting the timing and amount of assets we can recover in rates.

15

The rates we charge are regulated by the PUCT and certain cities and are subject to cost-of-service regulation and earnings oversight. This regulatory treatment does not provide assurance as to achievement of earnings levels or recovery of actual costs. Our rates are based on an analysis of our costs and capital structure in a designated historical test year, as reviewed and approved in a regulatory proceeding. As a result, the rates we are allowed to charge will generally not exactly match our costs at a given point in time, which is often referred to as regulatory lag, and which could materially and adversely affect our financial condition, cash flows, and results of operations.

Interim DCRF and TCOS rate adjustments, also known as capital trackers, have been implemented to help reduce regulatory lag and allow us to recover the cost of certain distribution and transmission investments, respectively, before the investments are considered for prudency in a base rate review. In June 2023, legislation was enacted by the Texas Legislature that increased the number of interim DCRF rate adjustment applications that may be filed by utilities in a single year for certain distribution-related investments from one application to up to two applications per year, shortened the administrative process for the proceedings to 60 days, which deadline the PUCT may extend by up to an additional 15 days, and removed or modified certain restrictions on when a utility may file a DCRF application. Under PUCT rules, we can file up to two interim TCOS rate adjustment applications in a calendar year to reflect changes in our invested transmission capital. These interim rate applications, however, are subject to a regulatory proceeding and PUCT approval, and we can make no assurance that interim rate updates will result in full cost recovery. Investments included in capital trackers are also subject to prudence review by the PUCT in the next base rate review following such adjustments, with a potential for the PUCT to also order refunds of previously collected amounts if a particular investment is found to be imprudent or inappropriately included in an interim rate adjustment. In addition, while these interim rate adjustments help reduce regulatory lag, they do not fully eliminate the regulatory lag between when a capital investment goes into service and when we begin to start recovering the costs of such investment in rates.

Also in June 2023, legislation was enacted by the Texas Legislature permitting an electric utility to file a plan to increase the resiliency of its transmission and distribution system and provided for additional recovery options for certain of those costs, including through deferral of distribution-related costs to regulatory assets. The PUCT adopted rules to implement the legislation in January 2024 that, among other things, outline the required elements of a resiliency plan and details of the cost recovery options. Under the rules adopted by the PUCT, implementation of a resiliency plan is subject to review and approval by the PUCT. Utilities may also apply for a specific rider to recover certain resiliency-related costs in rates, or, upon approval of a plan, utilities may defer all or a portion of distribution-related resiliency costs as a regulatory asset, with recovery of the regulatory asset through the interim DCRF rate adjustment mechanism or a base-rate proceeding. Implementation of a resiliency plan is subject to review and approval or modification of the specific plan by the PUCT. While we currently anticipate filing a plan in the first half of 2024, we can make no assurance that the PUCT will approve our plan or that the available cost recovery mechanisms will result in full recovery of all costs in our plan or a reduction of regulatory lag compared to existing recovery mechanisms.

In accordance with PUCT rules, we must file a comprehensive base rate review within four years of the last order in our most recent comprehensive rate proceeding, unless an extension is otherwise approved by the PUCT. Pursuant to these rules, our next comprehensive base rate review is required to be filed by June 2027. However, the PUCT or any city retaining original jurisdiction over rates may direct Oncor to file a base rate review, or Oncor may voluntarily file a base rate review, any time prior to that deadline.

While rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital, there can be no assurance that the PUCT in a base rate review will judge all of our costs, including invested capital and costs included in a regulatory asset reported on the balance sheet, to have been prudently incurred and therefore fully recoverable. The approved levels of recovery could be significantly less than our requested levels, and the approved timing for recovery of regulatory assets could differ from our proposed timelines. There can also be no assurance that the PUCT will approve any other items requested by us in any rate proceeding. Intervening parties in our rate proceedings (including, but not limited to, governmental agencies, cities in our service territory, customers, and consumer groups) can challenge, and have in the past challenged, various portions of our rate proceedings, and such challenges, as well as any recommendations from the administrative law judges overseeing proceedings, could influence the PUCT’s decisions in those proceedings. Failure to receive approval of our requests in any rate proceeding could adversely impact our financial condition, results of operations, cash flows, liquidity and/or business prospects, and those impacts, could be material.

In addition, because our rates are set based on a historical test year, there can be no assurance that the rates set in any base rate review will produce full recovery of our actual post-test year costs and/or the full return on invested capital

16

allowed by the PUCT, particularly during periods of increased capital spending by us, high inflation or increases in general interest rates resulting in increased costs incurred by us relative to our most recent base rate review. In recent years, we have not in fact earned our full regulatory authorized return on invested capital.

To the extent the regulatory process limits our ability to recover our costs in a timely manner, it could also materially and adversely impact our financial condition, results of operations, cash flows, liquidity and/or business prospects. The regulatory process by which rates are determined is subject to change as a result of the legislative process or rulemaking. Changes to interim adjustment mechanisms or the base rate review process could increase regulatory lag and otherwise impact our ability to recover our costs in a timely manner.

We are subject to various mandatory regulatory standards and requirements, including with respect to service quality, reliability, and weatherization of facilities. Efforts to comply with those standards could subject us to higher operating costs and/or increased capital expenditures, and non-compliance with applicable standards or expectations could have a material adverse effect on our business.

As a regulated transmission and distribution utility, our operations are subject to multiple regulatory standards and requirements. The PUCT has jurisdiction with respect to ensuring the service quality and reliability of the delivery of electricity to retail customers by electric utilities and has established various operational standards, including reliability standards and weatherization requirements, which apply to each utility. The FERC has jurisdiction with respect to ensuring the reliability of electric transmission service, including transmission facilities owned by utilities within ERCOT. The FERC has designated NERC to establish and enforce reliability standards (including cybersecurity and physical security standards), under the FERC’s oversight, for all owners, operators and users of electric transmission services. The FERC has approved the delegation by NERC of compliance and enforcement authority for reliability in the ERCOT region to Texas RE. 

Compliance with mandatory regulatory standards, such as those relating to service quality, reliability and weather preparedness, is subject to regular reporting, reviews and audits. We cannot predict the outcome of any such reviews and audits or related potential enforcement actions. We must report to the PUCT concerning our performance with respect to the applicable reliability standards on an annual basis. We are also required to file declarations certified by our chief executive addressing our weather preparedness with ERCOT twice a year, regarding our compliance with the PUCT’s winter weather preparedness and summer weather preparedness measures, respectively. In addition, the PUCT requires that ERCOT conduct inspections of our transmission facilities to determine compliance with weather preparation measures and report deficiencies to the PUCT. Also, as a NERC registered entity, we are subject to periodic audits by Texas RE of our compliance with operations and critical infrastructure protection standards, including reliability standards. These audits will occur as designated by Texas RE at a minimum of once every three years. While we expect to recover costs and expenditures from customers through regulated rates related to such compliance costs, there can be no assurance that the PUCT will approve full recovery of such costs or the timing of any such recovery. If we were found to be noncompliant with applicable reliability/service quality standards or weatherization requirements, we could be subject to sanctions, including monetary penalties. Penalties imposed by the PUCT, Texas RE, the FERC and/or NERC would not be recoverable from customers through regulated rates and could have a material adverse impact on our financial condition, results of operations and cash flows.

To maintain compliance with mandatory service quality, reliability and weatherization standards/requirements, or to meet our reliability goals, we may be subjected to higher-than-expected operating costs (including related to additional employee and contractor resources needed to support compliance efforts) and/or increased capital expenditures to construct, operate, and maintain transmission and distribution infrastructure. Texas has been experiencing significant and rapid population and business growth in recent years and we believe that such growth will continue in future years, requiring additional electricity delivery facilities to serve the increased electricity demand on our system. Increased growth on our system and the pace of that growth could impact reliability of service. While our capital expenditure plans include projects to address reliability, there can be no guarantee that such projects will address all customer reliability expectations, and failure to meet such customer expectations could adversely impact our reputation.

Risks Related to Our Business and Operations

Cyber-attacks on us or our third-party vendors could disrupt business operations, initiate the loss or disclosure of critical operating or confidential data, have an adverse impact on our reputation, and expose us to significant liabilities.

17

As an owner and operator of critical infrastructure assets, we are subject to cybersecurity threats from domestic and foreign threat actors who wish to disrupt our electricity delivery operations and/or the ERCOT bulk power grid. In particular, U.S. government warnings have indicated that infrastructure assets such as electric transmission and distribution systems may be specifically targeted by both foreign and domestic actors, including as a result of increased worldwide conflict and domestic extremism.

We are subject to evolving cyber risks related to adversaries attacking our technology infrastructure and platforms and the technology infrastructure and platforms of third-party vendors. With the proliferation of computing and telecommunications technologies and various digital tools used by us in our business and engagement with our customers, cyber risk arises in multiple areas of our operations. While we have not experienced a cybersecurity incident to date that has had a material impact on Oncor, we have experienced, and expect to continue to experience, threats and attempted intrusions into our technology systems and platforms. Our third-party vendors have been subject, and will likely continue to be subject, to acts that disrupt or attempt to disrupt the services they provide to us. We face various cyber threats, including malware intrusion, computer viruses, unauthorized access attempts, ransomware attacks, social engineering attacks, hacktivism and insider threats. Certain of these cyber threats have seen changes, and we expect to continue to see changes, in sophistication with the advancement of technology, including the adoption of artificial intelligence. As domestic and global cyber threats are on-going and increasing in sophistication, magnitude and frequency, our transmission, distribution and technology infrastructure may be targets of state-sponsored attacks, terrorist activities, or other threats, including attacks designed to collect ransoms or inflict large-scale harm on us, our customers or our service territory. Geopolitical events could increase those cyber threats. Any breach of cyber/data security measures could result in a material and adverse impairment of our ability to operate, monitor and control our technology, transmission and distribution assets (which could impact the stability of the ERCOT power grid), conduct our normal operations, process customer information, and comply with regulatory and disclosure obligations. A cybersecurity breach could limit or disable communications, including communications within our technology platforms and between our technology platforms and systems operated by third parties. In the ordinary course of business, we also collect and retain information that could be sensitive in nature, including customer information and personal information about employees, and a cybersecurity breach could result in the release of such confidential information.

Some of the technology systems, hardware, software, and technical applications and platforms used in our business are managed, hosted, provided or used by third parties to assist in our business operations. Our third-party vendors have been subject, and will likely continue to be subject, to acts that disrupt or attempt to disrupt the services they provide to us. Threat actors could also attempt to use our third-party vendors as a conduit to attack us. In addition, our operations in ERCOT also require communication with certain third-party systems, and disruptions in those systems could impact our operations. If our third-party vendors or any third-party systems integral to operations in the ERCOT market are impacted by cyber-attacks or are otherwise unable to perform the services they provide to us, our operations could be impacted, which could negatively affect our results of operations, financial condition and/or reputation. In addition, the theft, damage, or improper disclosure of sensitive data held by these third parties may subject us to further harm.

Any loss of control of our critical infrastructure, including control or disruption of our technology platforms, or loss of confidential or proprietary data through a cybersecurity breach, including a breach involving one of our third-party vendors, could adversely affect our reputation, expose us to material legal and regulatory claims and fines, require compliance with notification and monitoring regulations, expose us to significant remediation and compliance costs, impair our ability to execute on business strategies and/or materially adversely impact our results of operations, financial condition, liquidity and/or cash flows.

We develop and maintain systems and processes aimed at identification, protection, detection, response and recovery from cybersecurity incidents, which require significant investment, maintenance, and ongoing monitoring and updating as threats, technologies and regulatory requirements change. There can be no assurance that these systems and processes will be successful in mitigating all risks relating to cybersecurity incidents. Systems and processes are also subject to vulnerabilities related to social engineering and insider threats. In addition, due to the nature of cybersecurity incidents, and the evolving threat landscape, updates and enhancements to such systems and processes may require complex solutions that could require significant time and resources. We are also subject to various laws and regulatory standards relating to our operations and information disclosure, including required compliance with NERC cybersecurity standards. Additional cybersecurity requirements could also be applied to us in the future. Changes in existing standards or the imposition of new standards could increase our compliance costs and our exposure to the potential risk of violations of such standards.

18

While we maintain insurance, including cyber liability insurance, this insurance is limited in scope and subject to exceptions, conditions and coverage limitations and may not cover any or all of the costs associated with the consequences of any cybersecurity breach. Likewise, our ability to obtain insurance at rates we believe are commercially reasonable, and the cost of and coverage provided by such insurance, could be affected by events outside our control. In addition, should a cybersecurity breach result in regulatory fines or penalties due to non-compliance with a mandatory security standard, such fines or penalties would not be recoverable through rates.

Severe weather, natural disasters, wildfires and other emergency events could adversely impact us.

Our electric delivery facilities and other assets are located in over 120 counties in Texas and could be, and have in the past been, damaged or impacted by severe weather events, such as significant storms, as well as natural disasters, wildfires or other emergency events. Our service territory covers a highly variable range of geographic, climatic, and vegetative regions, and weather conditions can vary significantly across our service territory. Any such events that cause extensive damage on our system or that affect the reliability of the ERCOT grid and market generally (including the amount of generation capacity available for delivery by us to our customers) could have a material adverse impact on us, including causing disruptions in our ability to provide electricity delivery services, negatively impacting the reliability of our electricity delivery services, increasing our operation and maintenance expenses or our capital expenditures to repair or replace damaged facilities or equipment, and causing disruptions in planned projects, property damage, decreased volumes of electricity delivered, and personal injuries or loss of life for which we could face legal actions or risks, negative public perception, and regulatory, legislative, or legal actions. In addition, wildfires caused, or allegedly caused, by our transmission and distribution assets or our operation or maintenance practices, could expose us to costs, fines, penalties, reputational harm, and other liabilities, including for economic damages, personal injury, loss of life, or property damage. Any costs and liabilities relating to severe weather events, natural disasters, wildfires or other emergency events may not be fully covered by our insurance policies and may not be fully recovered in rates, and any rate recovery may be delayed.

Effects of climate change, including natural disasters, severe weather and other related phenomena, and regulatory and legislative developments related to climate change, including mandatory reporting requirements, may have a material adverse effect on our business, financial condition, results of operations and cash flows.

Natural disasters, severe weather, and other related phenomena could become more prevalent and unpredictable as a result of climate change or other factors, which could negatively affect our business and financial condition to the extent such events occur in or impact our service territory or lead to constraints in our supply chain. Customer energy needs vary with weather conditions, primarily due to fluctuations in temperature and humidity. To the extent weather conditions are affected by climate change, customer energy use could increase or decrease depending on the duration and magnitude of the changes. Weather conditions also impact transmission and distribution system operations. For example, exceptionally warm weather conditions for a long duration, which generally would result in increased customer energy usage, would also result in increased operational risks for transmission and distribution infrastructure, such as the risk of equipment malfunction due to continuous operation. Hot, dry weather conditions such as that experienced in Texas during the summer of 2023 could also increase the risk of wildfires, and such conditions could worsen as a result of climate change. Severe weather events, natural disasters or other related phenomena could also cause disruptions in our ability to provide service and lead to outages. Prolonged power outages to customers and business interruptions from outages could damage our reputation and have a material adverse effect on our business, financial condition, results of operations and cash flows.

Moreover, local, state, or federal legislative or regulatory initiatives may attempt to control or limit the causes of climate change, including greenhouse gas emissions, such as carbon dioxide and methane. Legislation or regulation of emissions, including mandatory reporting requirements, could subject us to increased litigation risks and materially increase costs to our operations as well as to our customers and suppliers. They could also provide a cost advantage to alternative energy sources or result in other costs or requirements, such as costs associated with the adoption of new infrastructure and technology to respond to new mandates. Developing and implementing plans for compliance with voluntary or mandatory climate commitments can also lead to additional capital, personnel and operation and maintenance expenditures. Increased costs related to these compliance activities could adversely affect our business, financial condition, results of operations and cash flows.

Legislation, regulation, or customer initiatives to combat climate change could also have an impact on operations and demand in the ERCOT market, which could in turn impact us. For instance, increased electrification in the ERCOT market, particularly through oil and gas producers electrifying their operations and widespread electrification of vehicles, could result in significant increased demand on the ERCOT system. Such increased demand could create operational and

19

reputational risks to meet customer reliability expectations. Increased electric infrastructure spend across the country as a result of climate change initiatives could also impact our supply chain by increasing the costs and/or decreasing the availability of equipment and materials necessary for transmission and distribution operations.

As an owner and operator of electricity delivery facilities, we face significant operational risks, including the risk of physical attacks on our infrastructure, that could adversely affect our results of operations and financial condition, and insurance may not fully cover any losses resulting from such risks.

The construction, ownership, operation and maintenance of electricity delivery facilities involves many operational risks, including equipment breakdown, failure of facilities, lack of sufficient capital and unexpected costs to maintain the facilities, replacement or refurbishment of aging infrastructure, equipment interruptions, design or construction flaws in equipment or facilities, supply chain disruptions, inflation, fires, explosions, impact of unusual or adverse weather conditions or other natural events, human operation errors, and interrupted or degraded service on key technology platforms, as well as the risk of performance below expected levels of efficiency or reliability, the occurrence of any of which could result in lost revenues, regulatory penalties for failure to meet reliability or other standards, and/or increased expenses that may not be recoverable through rates. There are also many hazards associated with the ownership, operation, and construction of electricity transmission and distribution assets, and these hazards expose us to risk of personal injury and loss of life, damage or destruction of property, or environmental damage, any of which could result in liabilities to our business.

In addition, we face threats from threat actors who wish to disrupt the ERCOT bulk power grid or electricity delivery operations in our service territory by physically damaging our transmission and distribution assets. We also face threats related to vandalism, theft, trespassing and acts of civil disobedience that could result in interruptions to our operations. In recent years, physical attacks on utility assets have increased in frequency and severity across the nation. In 2023, in response to the rise of such incidents, the Texas Legislature passed legislation implementing criminal penalties for certain incidents involving damaging or vandalizing critical electric infrastructure facilities. A physical attack on our assets could also interfere with normal business operations and affect our ability to control our transmission and distribution system. Certain of the various internal systems we use to conduct our businesses are highly integrated. Consequently, a breach in any one key physical asset could potentially impact other areas of our system. A physical security breach could adversely affect our reputation, expose us to material regulatory penalties and/or materially affect our results of operations, liquidity and financial condition.

A significant number of our facilities were constructed many years ago; older transmission and distribution equipment, even if maintained in accordance with good engineering practices, may require significant expenditures to keep operating at peak efficiency or reliability. A risk of increased maintenance and capital expenditures arises from damage to facilities due to storms and other severe weather events, natural disasters, wildfires, wars, accidents, terrorist or criminal acts, cyber-attacks, and other catastrophic events. Further, our ability to successfully and timely complete capital improvements to existing facilities or other capital projects is contingent upon many variables and subject to substantial risks. Should any such efforts be unsuccessful, we could be subject to additional costs that may not be recoverable through rates and/or the write-off of our investment in the capital project or improvement.

Insurance, warranties or performance guarantees may not cover all or any of the lost revenues or increased expenses that could result from the risks discussed above. Likewise, our ability to obtain insurance at rates we believe are commercially reasonable, and the cost of and coverage provided by such insurance, could be affected by events outside our control, including the willingness of insurers to provide such coverage. In addition, costs incurred in connection with the hazards associated with the operation and maintenance of electricity delivery facilities may not be fully recovered through rates. If the amount of insurance is insufficient or otherwise unavailable, and if we are unable to fully recover in rates the costs of uninsured losses, our financial condition, results of operations, or cash flows could be materially affected.

Our business could be adversely affected by health epidemics and pandemics.

We face risks related to health epidemics and pandemics, which could lead to the disruption of our business operations by impacting the global economy and our employees, REPs, end-users, wholesale customers, network transmission customers, service providers, vendors and suppliers. These effects could also have a variety of adverse impacts on us, including reduced demand for electricity, delayed or delinquent customer payments to us (including as a result of end use customer failures to pay REPs and/or any state or national moratoriums on customer disconnections), slowed growth in our service territory, reduced availability or productivity of our workforce, constraints on our supply

20

chain, increased supplier, labor and contractor costs, reduced labor or contractor availability, impairment of goodwill or long-lived assets, increased pension funding requirements due to a decline in pension asset values, impairment of our ability to develop, construct and/or operate electricity delivery facilities, and impairment of our ability to access funds from financial institutions and capital markets.

We operate within the ERCOT market, and significant changes to the ERCOT market structure or within the ERCOT market, including the economic environment in the ERCOT market, could adversely impact our business.

Our business is built around the ERCOT market and, as a result, significant changes within ERCOT or to the ERCOT market structure that impact transmission and distribution utilities, including additional regulatory requirements or oversight, could materially and adversely impact our business, operations, financial condition, results of operations, and/or business prospects.

ERCOT is subject to oversight by the PUCT and the Texas Legislature, and either entity could impose changes to the ERCOT market that could impact us. Since February 2021, when winter storm Uri resulted in insufficient generation in the ERCOT market and prolonged power outages, the PUCT and the Texas Legislature have instituted various measures relating to operations in the ERCOT market. Both the PUCT and the Texas Legislature continue to actively review the operations, as well as the overall design, of the ERCOT market. Electric industry and electric grid related matters were heavily discussed during the 2023 regular session of the Texas Legislature, and significant changes to the ERCOT market were adopted. We cannot predict whether, or to what extent, the decisions by the PUCT to implement these changes and/or any additional legislation or regulations relating to the ERCOT market will impact our business.

We derive substantially all of our revenues from operations in the ERCOT market, which represents approximately 90% of the electricity consumption in the State of Texas. Economic weakness in the ERCOT market could lead to reduced demand for electricity in the ERCOT market and slowing growth in our service territory, which could have a material adverse impact on our results of operations, financial condition, cash flows, and capital expenditure projections.

Our capital deployment plan may not be executed as planned, which could adversely impact our reputation, reliability, financial condition and results of operations.

There can be no guarantee that the execution of our capital plan will be successful or done in accordance with current anticipated spend amounts, and there can be no assurance that the capital investments we currently intend to make in connection with our electricity delivery business will be implemented as contemplated or at all, or, if implemented, produce the desired improvements to service and reliability or cost management. Furthermore, there can be no guarantee that our capital investments will ultimately be recoverable through rates. For more information regarding the limitation on recovering the value of investments using rates, see “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Key Factors Relating to Future Earnings and Results of Operations.”

While our capital expenditure plans include projects to successfully maintain or replace our aging infrastructure and address the expected growth of electricity demand in our service territory, particularly as a result of increased commercial and industrial demand and electrification goals of customers, there can be no assurance that any such projects will be completed in a timely manner or at all, or fully meet all customer requirements at all times. Projects to construct, upgrade, or maintain transmission and distribution infrastructure are subject to various additional uncertainties, including regulatory approvals, land/easement acquisition (including requirements and constraints relating to eminent domain), labor and contractor availability, volatile commodity prices, supply chain disruptions and inflation, costs of materials and labor, and forecasts of future electric load needs. Execution of our capital plan could also be impacted by capital availability, macroeconomic conditions, regulations, ERCOT policies or directives, ERCOT grid needs, weather, natural disasters, wildfires, emergency events, equipment malfunction or failure, accidents, terrorist attacks, cybersecurity events, failure of technology platforms, or other events outside of our control. Failure to execute on our capital deployment program as planned could adversely impact service reliability as well as our reputation, financial condition, and results of operations.

21

The litigation environment in which we operate poses a significant risk to our business.

We are involved in the ordinary course of business in a number of lawsuits arising out of our business operations, including personal injury litigation and litigation relating to power outages, among other matters. For example, lawsuits have been filed against various market participants, including us, relating to the power outages resulting from winter storm Uri in February 2021. The litigation is currently consolidated in Texas state court in Harris County, Texas, as part of a multi-district litigation proceeding. We cannot predict whether or to what extent any of such litigation will impact our business. Judges and juries in the State of Texas have demonstrated a willingness to grant large verdicts, including punitive damages, to plaintiffs in personal injury, property damage and business tort cases. We use appropriate means to contest litigation threatened or filed against us, but the litigation environment in the State of Texas poses a business risk.

Our revenues are concentrated in and collected through a small number of customers and a significant delay or default in payment could adversely affect our cash flows, liquidity, financial condition and/or results of operations.

Our revenues from each of the transmission and distribution operations of our business are concentrated in a small number of customers. As of December 31, 2023, our revenues from our distribution operations are primarily collected from over 100 REPs that sell the electricity we distribute to end-use consumers in our certificated service area. REPs are generally noninvestment grade. Revenues from REP subsidiaries of our two largest customers, collectively represented 25% and 23%, respectively, of our total operating revenues for the year ended December 31, 2023 and 26% and 24%, respectively, of our total operating revenues for the year ended December 31, 2022. We collect network transmission revenues from approximately 40 different customers, consisting primarily of distribution companies, cooperatives and municipally-owned utilities. Currently, the majority of this network transmission customer revenue comes from customers who are investment grade and, as a result, generally considered low credit risk. PUCT rules allow for the recovery of uncollectible amounts due from REPs (but not network transmission customers) through rates. Adverse economic conditions, structural problems in the market served by ERCOT or the financial difficulties of one or more customers could adversely impact the credit quality of our customers, impair the ability of these customers to pay for our services or could cause them to delay such payments. We depend on these customers to timely remit these revenues to us. Delays or defaults in payment from customers could materially and adversely affect our cash flows, liquidity, financial condition and/or results of operations, particularly in the event of any moratoriums on the ability of REPs to disconnect customers for nonpayment or other regulatory actions that impact our receipt of electricity delivery charges owed to us.

We are dependent upon a limited number of suppliers and service providers for certain of our operations. If any of these suppliers or service providers fails to perform on their agreements with us or became unable to perform on expected or acceptable terms, it could disrupt our business and have an adverse effect on our cash flows, liquidity, financial condition and/or results of operations.

We rely on suppliers and service providers to provide us with certain specialized materials and services, including for construction, maintenance and repair of electricity delivery facilities and power lines, information technology and customer operations. In certain instances, our operations are dependent upon a limited number of suppliers and service providers, and we often compete with other companies both in our industry and outside of our industry for materials and services from certain suppliers and service providers. The financial condition of our suppliers and service providers or their ability to perform has been or may be adversely affected by local, national and global events, including health epidemics or pandemics, climate change, severe weather events, natural disasters, supply chain issues, demand, wars, terrorist attacks, regulations, or general economic conditions, such as credit risk, commodity availability and pricing, inflation, labor availability and cost, and turbulent macroeconomic events. We have seen and expect to continue to see increased pricing from service providers as a result of the contractor labor market and competition for equipment and materials. Because many of the tasks of these suppliers and service providers require specialized electric industry knowledge and equipment, if any of these parties fail to perform or otherwise fully satisfy their contractual obligations, choose not to renew contracts, go out of business or otherwise become unable to perform on terms acceptable to us, or unexpectedly delay performance or increase the cost of performance, we may not be able to transition to substitute suppliers or service providers in a timely manner, on terms acceptable to us, or at all. This could delay our construction and improvement projects, increase our costs and/or disrupt our operations, which could negatively impact our business, financial condition, results of operations, cash flows, liquidity, reputation and/or business prospects. In addition, we could be subject to fines or penalties in the event a delay resulted in a violation of a PUCT or other regulatory order.

22

Disruptions in our supply chain, including as a result of competition for materials, the contractor labor market and inflation, could negatively impact our operations and corporate strategy.

Our operations and business plans depend on the domestic and global supply chain to procure the equipment, materials and other resources necessary to build and maintain transmission and distribution infrastructure and provide electricity delivery services in a safe and reliable manner. The delivery of components, materials, equipment and other resources that are critical to our business operations and corporate strategy has been, and may continue to be in the future, restricted by domestic and global supply chain challenges. In addition, we have seen and expect to continue to see increased competition for certain equipment, goods and materials necessary for our transmission and distribution operations, resulting in increased pricing, decreasing availability of certain materials and longer lead times for delivery. Reduced availability of necessary materials and delays in delivery has, and could continue to delay maintenance, repair and construction projects, which could have an adverse impact on our reputation, capital plan, cash flows, liquidity, financial condition and/or results of operations. International tensions as well as a decline in the manufacturing workforce could further exacerbate supply chain challenges. Increasing cost and availability of labor and inflation have also contributed to supply chain disruptions and higher construction and operating costs. Higher than anticipated costs in the future could have an adverse impact on our business, financial condition, results of operations, liquidity, and cash flows.

Our future success is dependent on our ability to attract and retain qualified personnel and identify and develop talent, and failure to attract and retain a highly qualified workforce, particularly in senior management as well as operational roles, could adversely impact our operations.

Our future success will depend on our ability to continue to attract and retain highly qualified personnel. We compete for such personnel with many other companies, both in and outside our industry, as well as government entities and other organizations. Our workforce strategy to attract, develop, reward and retain a qualified workforce includes a market competitive total reward strategy along with talent development and succession planning to retain key talent and build succession strength for future leadership roles. However, we may not be successful in retaining our current personnel or in hiring or retaining qualified personnel, particularly in certain highly technical or specialized roles, in the future. In addition, we have incurred, and may continue to incur, increased costs in order to remain a competitive employer in a highly competitive labor market. Further tightening of the labor markets may adversely affect our ability to attract new personnel and retain existing personnel, which could adversely impact our operations. In addition, because of our reliance on the expertise of our senior management team, our future success depends in part on our ability to identify, retain and develop talent to succeed our senior management. Senior management succession planning is, and we expect it will continue to be, critically important to the successful implementation of our strategies.

Approximately 15% of our employee population is retirement eligible. Failure to adequately replace those retiring employees could impact our productivity and reputation. Failure to transfer significant internal historical knowledge and expertise to new employees may adversely affect our ability to manage and operate our business. In addition, limited availability of contract resources, a mismatch of existing skillsets to future needs, and an aging workforce without appropriate replacements could lead to operating challenges such as a lack of resources, loss of internal historical knowledge or a lengthy time period associated with highly technical or specialized skill development. Our costs, including costs to replace employees, productivity costs, safety costs, and cost of contract labor, may rise and affect our ability to manage and operate our business.

Our revenues and results of operations are seasonal and significantly impacted by weather events and other electricity usage drivers.

A significant portion of our revenues is derived from rates that we collect from REPs based on the amount of electricity we distribute to end-use customers on behalf of such REPs. Deliveries of electricity to residential and commercial customers are influenced by time of year, fluctuations in temperature and other weather events. Thus, our revenues and results of operations are subject to seasonality, weather events and other electricity usage drivers, with revenues being highest in the summer. Unusual weather patterns, including as a result of climate change or other factors, could significantly impact revenues.

The costs of providing pension benefits and OPEB and related funding requirements may have a material adverse effect on our financial condition, results of operations and cash flows.

23

We offer certain pension and health care and life insurance benefits to eligible employees and their eligible dependents upon the retirement of such employees through pension plans and OPEB plans, and also have contractual obligations related to certain pension and OPEB benefits of eligible retirees of our former affiliates. See Note 9 to Financial Statements for more information regarding pension and OPEB obligations.

Our costs or share of the costs of providing pension and OPEB benefits and related funding requirements are dependent upon numerous factors, assumptions and estimates and are subject to changes in these factors, assumptions and estimates, including the market value of the assets funding the pension plans and OPEB plans and future benefit costs for pension plans and OPEB plans. Benefits costs and related funding requirements could also increase or decrease due to changes in employee demographics (including but not limited to age, compensation levels and years of accredited service), the level of contributions made to retiree plans, mortality assumptions, expected and actual earnings on plan assets, general interest rates, and the discount rates used in determining the projected benefit obligation. Changes made to the provisions of the plans may also impact current and future benefit costs. Significant unplanned increases in benefit costs could have an adverse impact on our financial condition, results of operations, and/or cash flows. See Note 9 to Financial Statements, “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates—Defined Benefit Pension Plans and OPEB Plans” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition—Liquidity and Capital Resources—Pension and OPEB Plans Funding” for further information regarding pension and OPEB funding.

PURA provides for our recovery of pension and OPEB costs related to the regulated utility service of our employees as well as certain employees of our former affiliates, and we are authorized to establish a regulatory asset or liability for the difference between the amounts of pension and OPEB costs approved in current billing rates and the actual amounts that would otherwise have been recorded as charges or credits to earnings related to recoverable service. Amounts in these regulatory assets are ultimately subject to regulatory approval, and disallowance of any of these regulatory assets could have an adverse effect on our financial condition, results of operations and/or cash flows. At December 31, 2023 and 2022, we had recorded net regulatory assets (after taking into account related regulatory liabilities) totaling $291 million and $346 million, respectively, related to pension and OPEB costs, including amounts related to deferred expenses as well as amounts related to unfunded liabilities that otherwise would be recorded as other comprehensive income. See Note 2 to Financial Statements for further information regarding these regulatory assets.

We regularly evaluate opportunities to make selective strategic acquisitions involving regulated assets. Acquisitions involve various risks, and we may not be able to realize the anticipated benefits of any such acquisitions.

We regularly evaluate opportunities to make selective strategic acquisitions involving regulated assets. Additional equity or debt capital may be required to complete any acquisition. In addition, any acquisition may be structured in such a manner that could result in the assumption of secured or unsecured debt and other liabilities. Any such transaction may require PUCT and other regulatory approvals. An acquisition may involve risks relating to the combination of assets and facilities, the diversion of management’s attention and the impact on our credit ratings.

Insufficient electric capacity within ERCOT or disruptions at power generation facilities that supply power within ERCOT could interrupt and/or negatively impact our transmission and distribution services.

The electricity we transmit and distribute to REPs, electricity distribution companies, electric cooperatives and municipally-owned utilities is obtained by these entities from electricity generation facilities. We do not own any generation facilities. Electricity generation capacity and the mix of generation resources within ERCOT is not within our control. Electricity demand in ERCOT has increased in recent years and is expected to continue to increase. Demand may be further increased during periods of extreme weather, such as during the hotter than normal temperatures experienced in the summer of 2023, when ERCOT set ten new peak demand records and issued several requests to Texans to conserve power to avoid a power-supply emergency. In addition, the risk of insufficient generation capacity during extreme and prolonged cold temperatures continues to threaten reliability in the ERCOT market. In November 2023, NERC issued its winter reliability assessment and noted an increased risk of reserve shortage for the 2023-2024 winter season in the ERCOT market as compared to the previous winter due primarily to the increased load growth in ERCOT and lack of a corresponding growth in dispatchable generation resources. In the event insufficient generation capacity results in power outages, public perception of our industry as well as economic development in ERCOT could be adversely impacted. In addition, if electricity generation is disrupted or if power generation capacity is inadequate, our electricity delivery services may be diminished or interrupted, which could have an adverse impact on our reputation, results of operations, financial condition, and cash flows. In addition, we are subject to ERCOT directives with respect to the flow of power on the electric

24

grid. In the event of extreme weather or other emergency events that impact power availability within ERCOT, ERCOT could require us to reduce demand on the grid. If we are required by ERCOT to institute outages, it could negatively impact our reputation, our revenues from transmission and distribution services may be diminished or interrupted, and our results of operations, financial condition and cash flows may be materially and adversely affected.

The growth of DER and similar technologies or actions that decrease demand or consumption of electricity delivered by us may significantly adversely impact our business, including by limiting future infrastructure investments and reducing our ability to timely recover the cost of our investment in, and earn a reasonable return on, our electricity delivery facilities.

The electric industry is undergoing significant technological change, particularly regarding development and availability of DER, alternatives to traditional transmission and distribution solutions such as distributed generation (including solar panels and microgrids), batteries and other energy storage, energy efficiency technologies, demand response technologies (such as electric vehicle-to-grid or vehicle-to-home solutions) and other grid management solutions. Research and development activities are ongoing to improve existing and alternative technologies and services to produce and store electricity, and it is possible that advances in these or other technologies will reduce the costs of electricity production from these technologies to a level that will make these technologies more attractive to customers than relying on traditional sources of electricity. Such changes in technology, as well as public perception of DER and legislation or regulations relating to DER, could also alter the channels through which retail customers buy and receive electricity. For instance, the PUCT has instituted various projects reviewing the regulatory framework regarding DER and other non-traditional technologies, and in 2023 the first virtual power plants, which are multiple customer DER aggregated by a REP that coordinates the operation of those customers’ individual devices to collectively reduce demand on the grid or export power to the grid under an ERCOT instruction, were approved by the PUCT to offer and provide energy and ancillary services to ERCOT. As DER usage continues to grow, it could reduce the amount of or alter the nature of electricity delivery usage and demand on our system, complicate the operation of our delivery system (such as by increased multi-directional power flow), negatively impact the reliability of our system, or make investments in transmission and distribution infrastructure less desirable. Regulatory decisions made with respect to DER, including with respect to ERCOT market rules and transmission and distribution utilities’ ability to invest in non-traditional electricity delivery solutions, could adversely impact our costs, revenues, and operations. To the extent DER controlled by entities other than Oncor (including behind the meter alternatives and private use networks) become a more cost-effective or otherwise preferred option for certain customers, our revenues, financial condition, results of operations, cash flows, capital expenditures, and business prospects could be materially adversely impacted.

Also, electricity demand and usage could be reduced or modified by advances in technology that lower or alter the demand for electricity, governmental actions to require or incentivize reductions in electricity consumption, and other conservation or customer demand management efforts, which, absent regulatory changes related to how Oncor recovers investments in rates, could likewise significantly reduce our ability to timely recover the cost of our investment and earn a reasonable return on our electricity delivery facilities. Effective energy conservation or demand management by our customers could result in significantly reduced electricity demand and usage, or significantly slow the growth in demand and usage. Such a reduction, absent regulatory changes related to how Oncor recovers investments in rates, could materially adversely impact our revenues, financial condition, results of operations and cash flows.

Goodwill that we have recorded is subject to at least annual impairment evaluations, and as a result, we could be required to write off some or all of this goodwill, which may adversely impact our reported financial condition and results of operations.

In accordance with accounting standards, recorded goodwill is not amortized but is reviewed for impairment annually, or more frequently if certain conditions exist. Any reduction in or impairment of the value of goodwill will result in a charge against earnings, which may adversely impact our reported results of operations and financial condition. See Note 1 to Financial Statements for more information on our goodwill impairment assessment and testing.

25

Risks Related to Financial and Market Matters

Adverse actions with respect to our credit ratings could negatively affect our cost of debt and our ability to access capital.

Our access to capital markets and our cost of debt could be directly affected by changes in our credit ratings. Regulatory impacts, particularly in the ERCOT market, changes in our financial performance, liquidity needs, as well as unfavorable conditions in the capital markets, among other things, could result in credit agencies changing our credit ratings. In addition, specific regulatory decisions with respect to us could also have an impact on our credit ratings. Any adverse action with respect to our credit ratings could generally cause debt issuance and borrowing costs to increase and the potential pool of investors and funding sources to decrease. Our Credit Facilities also provide that interest rates charged for borrowings and commitment fees on undrawn amounts may be adjusted based on our credit ratings. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition—Liquidity and Capital Resources—Credit Rating Provisions and Material Debt Covenants—Material Debt Credit Rating, Financial, and Cross-Default Covenants” for more information on material credit rating covenants in our Credit Facilities and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Regulation and Rates” for more information on our base rate review.

In addition, most of our large suppliers and counterparties require an expected level of creditworthiness in order for them to enter into transactions with us. If our credit ratings decline, the costs to operate our business could increase because counterparties could require the posting of collateral in the form of cash-related instruments, or counterparties could decline to do business with us. In addition, if any adverse credit rating action takes place and causes our borrowing costs to increase, we may not be able to recover such increased costs if they exceed our cost of debt as approved by the PUCT in our most recent base rate review or subsequent base rate reviews.

Our credit ratings are currently higher than those of Sempra, our indirect majority equity owner. If credit rating agencies were to change their views of our independence from Sempra and its affiliates (other than the Oncor Ring-Fenced Entities), our credit ratings could decline. Despite our ring-fencing measures, rating agencies have in the past taken, and could in the future take, an adverse action with respect to our credit ratings in response to activities involving financing and liability management activities by our indirect majority equity owner.

Market volatility may impact our business and financial condition in ways that we currently cannot predict.

Because our business is capital intensive, we expect to rely on access to financial markets as a significant source of funding for capital requirements not satisfied by cash-on-hand, operating cash flows, our Credit Facilities, CP Program, or our AR Facility. It is likely we will incur additional debt in connection with our large capital expenditure projections, which include continuing significant investments in transmission and distribution infrastructure. Our ability to access the capital, credit, or commercial paper markets may be severely restricted, or limited entirely, due to market conditions at a time when we would like, or need, to access those markets, which could have an impact on our flexibility to react to changing economic and business conditions. Any such adverse market conditions could be due to circumstances completely outside of our control, such as a recession, depressed economic conditions, interest rates, political instability, pandemics, inflation, war, terrorism, sanctions, bank failures, or extreme volatility. In addition, the cost of debt financing may be materially and adversely impacted by changes in general interest rates. In 2023, we saw increased borrowing costs due to increases in general interest rates. In addition, bank failures and banking regulations have in the past created, and could in the future create, instability in the banking industry and the financial markets. Disruptions in the banking sector could increase the cost of capital and reduce our access to capital, lines of credit, and certain financing options. Even if we are able to obtain debt financing, we may be unable to recover in rates some or all of the costs of such debt financing if they exceed our cost of debt as approved by the PUCT in our most recent base rate review or subsequent base rate reviews, which could adversely affect our earnings and cash flows. The PUCT-approved cost of debt in our most recent base rate review, which was based on a 2021 test year and is reflected in our current base rates, is lower than our actual average cost of debt for the year 2023. We do not anticipate a change in our PUCT-approved cost of debt prior to a subsequent base rate review proceeding. Fluctuations in actual market returns as well as changes in general interest rates may also result in increased or decreased employee/retiree benefit costs in future periods. Additionally, disruptions in the capital, credit, and commercial paper markets could have a broader impact on the economy in general in ways that could lead to reduced electricity usage, slowing growth in our service territory, payment defaults by REPs or other customers, or failure by our suppliers to perform their contractual obligations, which could have a negative impact on our revenues, financial condition

26

or results of operations, or have an impact on our customers, counterparties and/or lenders, causing them to fail to meet their obligations to us.

Our ring-fencing measures may not work as planned, which may result in a bankruptcy court subjecting Oncor to the claims of its affiliates’ creditors.

Various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with a direct or indirect ownership interest in Oncor or Oncor Holdings. These enhancements are intended to minimize the risk that a court would order any of the Oncor Ring-Fenced Entities’ assets and liabilities to be substantively consolidated with those of Sempra or any of its affiliates or any other direct or indirect owners of Oncor or Oncor Holdings or their affiliates in connection with a bankruptcy of any such entities. Substantive consolidation is an equitable remedy in bankruptcy that results in the pooling of the assets and liabilities of the debtor and one or more of its affiliates solely for purposes of the bankruptcy case, including for purposes of distributions to creditors and voting on and treatment under a reorganization plan. Bankruptcy courts have broad equitable powers, and as a result, outcomes in bankruptcy proceedings are inherently difficult to predict. To the extent a bankruptcy court were to determine that substantive consolidation is appropriate under the facts and circumstances, then the assets and liabilities of any Oncor Ring-Fenced Entity that is subject to the substantive consolidation order would be available to help satisfy the debt or contractual obligations of the affiliated entity that is a debtor in bankruptcy and subject to the same substantive consolidation order. If any Oncor Ring-Fenced Entity were included in such a substantive consolidation order, the secured creditors of Oncor would retain their liens and priority with respect to Oncor’s assets.

See Note 1 to Financial Statements and “Items 1. and 2. Business and Properties-Ring-Fencing Measures” for additional information on our ring-fencing measures.

In the future, we could have capital needs that could be difficult to satisfy under some circumstances, including existing limitations on our ability to incur indebtedness and uncertain financial market conditions.

Our operations are capital intensive. We expect to rely on access to financial markets as a significant source of funding for capital requirements not satisfied by cash-on-hand, operating cash flows, our Credit Facilities, CP Program, or our AR Facility. We have also historically retained earnings that could have been distributed to our members and invested them in the business. In addition, from time to time we have received capital contributions from our members and could seek member capital contributions in the future to address capital needs. However, our LLC Agreement provides that no member may be required to make any additional capital contributions to us.

The inability to raise capital on favorable terms or access liquidity facilities, particularly during times of uncertainty, could adversely impact our ability to sustain and grow our business and would likely increase capital costs that may not be recoverable through rates. Accordingly, there can be no assurance that the capital, credit, and commercial paper markets will continue to be a reliable or acceptable source of short-term or long-term financing for us. Our access to the capital, credit, and commercial paper markets, our Credit Facilities and AR Facility, and the pricing and terms we receive in the financial markets, could be adversely impacted by various factors, such as:

changes in financial markets that reduce available credit or the ability to obtain or renew liquidity facilities on acceptable terms;

perceived risks related to the industry in which we operate;

economic weakness in the ERCOT market;

changes in interest rates;

a deterioration of our credit or a reduction in our credit ratings;

a deterioration of the credit or insolvency or financial distress of one or more lenders under our Credit Facilities or our AR Facility that affects the ability of the lender(s) to make loans to us;

a deterioration of the credit of Sempra or its affiliates (other than the Oncor Ring-Fenced Entities) or a reduction in the credit ratings of Sempra or such affiliates that is perceived to potentially have an adverse impact on us despite the ring-fencing of the Oncor Ring-Fenced Entities from Sempra and such affiliates;

changes that impact accounts receivables from REPs and related rights resulting in a change to eligible receivables under our AR Facility;

a material breakdown in our risk management procedures; and

changes that restrict our ability to access our Credit Facilities or our AR Facility.

27

We are also subject to certain limitations on our ability to incur indebtedness. We are required to maintain a regulatory capital structure at or below the debt-to-equity ratio established periodically by the PUCT for ratemaking purposes. Currently, our authorized regulatory capital structure set by the PUCT is 57.5% debt to 42.5% equity. At December 31, 2023, our regulatory capital structure was 55.8% debt to 44.2% equity. Our ability to incur additional long-term debt is limited by our authorized regulatory capital structure and we are able to issue future long-term debt only to the extent that such issuance would not cause our capital structure to exceed the authorized regulatory debt-to-equity ratio. In addition, certain of our debt agreements contain debt-to-capital ratio covenants that effectively limit our ability to incur indebtedness in the future. At December 31, 2023, we were in compliance with these covenants. See “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financial Condition—Liquidity and Capital Resources—Credit Rating Provisions and Material Debt Covenants—Material Debt Credit Rating, Financial, and Cross-Default Covenants” for more information on these covenants. Also, because the $2B Credit Facility provides liquidity support to our CP Program, we treat CP Notes outstanding as a reduction to the available $2B Credit Facility borrowing capacity. See Note 5 to Financial Statements for further information regarding the $2B Credit Facility and CP Program.

Item 1C.CYBERSECURITY

Maintaining a robust cybersecurity strategy to safeguard and protect the confidentiality, integrity and availability of our critical infrastructure assets as well as all other information systems and the information residing in them is critically important to our business. We face various cyber threats, including malware intrusion, computer viruses, unauthorized access attempts, ransomware attacks, social engineering attacks, hacktivism and insider threats. In addition to the cybersecurity threats faced by any business with a cyber presence, as an owner and operator of critical infrastructure assets, we are subject to cybersecurity threats from domestic and foreign threat actors who wish to disrupt our electricity delivery operations and/or the ERCOT bulk power grid. With an ever-increasing share of our operational and administrative activity being dependent on our information systems, we strive to create a company-wide culture of cyber safety that continually monitors risk.

Our Cybersecurity Strategy

Our cybersecurity strategy is built on “defense-in-depth” as recommended by the National Institute of Standards and Technology. We have processes in place to identify, assess, and manage material risks from cybersecurity threats. We have developed and implemented, and we continue to develop and implement, protective measures to reduce risk, manage incidents, and sustain our security posture. For example, in our efforts to lower the risk of ransomware attacks, we have increased our cybersecurity operations by strengthening our defense-in-depth approach to protections and controls, operational resiliency, cyber hygiene and monitoring. Specific steps include tool deployments to mitigate ransomware threats and impacts, as well as implementation of practices and enhancements to minimize the risk of ransomware launching and spreading across the organization. An additional protective measure to reduce risk with respect to the unauthorized access to confidential and sensitive data in Oncor’s possession includes our data risk management (DRM) program. Our DRM program focuses on data loss prevention, including as the result of unauthorized access or acquisition, by taking proactive steps to limit confidential and sensitive information from being managed or distributed electronically in an unsecure manner. Led by our executive leadership team, as well as a governance committee and operational stakeholders, our DRM group provides formal guidance, including policies and standards, to reduce our data risk. We continue to participate, review, assess and adjust our mix of activities to improve our grid operations, digital perimeter security and information security.

We have policies and procedures in place to identify, protect, detect, respond and recover from cybersecurity incidents. The life cycle of our incident response includes: (i) preparation through employee training and drills, including regular simulation exercises that include management from various departments in addition to representatives from our information technology security team; (ii) detection and analysis of the cybersecurity incident; (iii) assembling the appropriate response team and escalating the incident to the appropriate parties internally and externally; (iv) containment, eradication, recovery and monitoring; and (v) post incident activity to document the root cause and discuss areas of improvement.

In accordance with our policies and procedures, we investigate any technological, computer, or network security event or incident within our networks or involving confidential and sensitive data maintained by Oncor, including events or incidents involving third-party vendors that interface with our networks or otherwise hold confidential and sensitive data maintained by Oncor. With respect to certain of our third-party vendors, we may also require such third-party vendors to notify us of any cybersecurity incident that may impact our operations or involve confidential and sensitive data maintained by Oncor. Multiple security operations centers monitor our digital environment at all times for anomalies, threats, and indicators of compromise. We have a variety of tests performed by internal and external parties related to the integrity of our networks, cyber protections and policies and procedures. Third-party security tests of our network, applications, perimeter, physical equipment and other areas of security are used to test cybersecurity readiness. When a cybersecurity threat either newly materializes or escalates, we elevate communication both internally and externally to ensure situational intelligence is both known and shared to help in defending against that threat.

We are also subject to mandatory and enforceable regulatory standards for critical infrastructure protection, which include cybersecurity-related standards. We are subject to periodic audits by Texas RE of our compliance with critical infrastructure protection standards.

29

We also participate in, and work with, multiple federal, state, industry, and academic groups dedicated to cybersecurity, such as the U.S. Department of Homeland Security’s Cybersecurity & Infrastructure Security Agency, the Federal Bureau of Investigations’ InfraGard, an ERCOT critical infrastructure protection working group, the Electricity Information Sharing and Analysis Center, and the Texas Information Sharing and Analysis Organization. This includes information-sharing and coordination with ERCOT, the PUCT, and other ERCOT market participants with a view toward protecting and enhancing the ERCOT grid from cyber and physical attacks and response preparation. In addition, we participate on various technical and advisory boards, such as the advisory board of the Energy Sector Security Consortium, Inc., a nonprofit organization that supports energy sector organizations with the security of their critical technology infrastructures, and the Electricity Subsector Coordinating Council. We believe that our participation and membership within these groups and organizations contributes to security improvements that directly impact our cyber operations.

We believe that cyber safety is everyone’s responsibility at Oncor. We take proactive steps to train, re-train, educate and test our workforce on cyber safety practices and work to strengthen the cyber community within our company. We require an annual cybersecurity training of all credentialled individuals and in October 2023 we held our 2nd annual cyber awareness month, which included informational events, speakers and additional training resources to increase our workforce’s engagement in cyber safety.

While we have not experienced a cybersecurity incident to date that has had a material impact on Oncor, we have experienced, and expect to continue to experience, threats and attempted intrusions into our technology systems and platforms. Our third-party vendors have been subject, and will likely continue to be subject, to acts that disrupt or attempt to disrupt the services they provide to us. Threat actors could also attempt to use our third-party vendors as a conduit to attack us. We are subject to evolving cyber risks related to adversaries attacking our technology infrastructure and platforms and the technology infrastructure and platforms of third-party vendors. See “Item 1A. Risk Factors—Cyber-attacks on us or our third-party vendors could disrupt business operations, initiate the loss or disclosure of critical operating or confidential data, have an adverse impact on our reputation, and expose us to significant liabilities.” A future cybersecurity incident could potentially have a material impact on our business, operations and financial condition. In addition, non-compliance with electric industry specific regulations or violation of laws could have financial penalties, as well as impact our reputation, which could materially impact our results of operations or financial condition. Cybersecurity risk has also contributed to, and is expected to continue to contribute to, increased capital expenditures and operation and maintenance expenses, including as a result of the need for additional hardware, software, equipment, personnel, training and third-party service providers, as well as increased cyber insurance costs.

Our Cybersecurity Team

Our management is responsible for assessing, managing and mitigating all risks relative to our business, including material risks from cybersecurity threats. Within our management team, assessment, management, and mitigation of cybersecurity threats is primarily overseen by our technology group, which has extensive experience in cybersecurity, technology, and digital grid operations. Our technology group is led by Joel Austin, our senior vice president and chief digital officer, and Malia Hodges, our senior vice president and chief information officer. Mr. Austin has over 34 years of technology operations, utility industry, and leadership experience, including more than 15 years of cybersecurity oversight experience. Ms. Hodges has 25 years of technology operations, utility industry, and leadership experience, including six years as our chief information officer, with responsibility in that role for management of Oncor’s technology function, including cybersecurity. Both Mr. Austin and Ms. Hodges are long-time members of the Edison Electric Institute security and technology policy committee, which focuses on working with federal agencies on cybersecurity risks relevant to the electric industry. Mr. Austin has testified on cybersecurity issues facing the State of Texas and the electric utility industry in front of multiple Texas legislative sub-committees and been asked to discuss cybersecurity risks with members of the US Congress. Mr. Austin and Ms. Hodges also work closely and regularly with PUCT staff and PUCT commissioners on cybersecurity risks and mitigations. We also have a designated chief information security officer who has over 42 years of experience in cybersecurity, a master’s degree in cybersecurity and a doctorate degree in cybersecurity/information assurance. Within our technology group, we maintain a dedicated cybersecurity group and 24/7/365 team that responds to and protects against cybersecurity risks. Our collective cybersecurity staff consists of a group of employees and contractors located inside and outside the state of Texas with a wide range of specialized skills and experience, including through service in the United States military and federal agencies, cybersecurity-related certifications, membership and advisory and board positions with industry groups and non-profit organizations focused on cybersecurity, and training in the cyber defense tools and methods we deploy, as well as various higher education degrees related to cybersecurity.

30

Governance

Cybersecurity risk is considered a significant corporate risk by management. Our technology security team provides our management with a weekly cyber update that discusses cybersecurity threats impacting Oncor. Management of our cybersecurity risks begins at the individual employee level, with each employee having responsibility for operating in a cyber safe manner, and flows up to our board of directors, which has overall oversight over Oncor’s corporate risk management efforts. The board of directors has delegated its risk management oversight to the Audit Committee, whose charter provides that it is responsible for discussing with management our major risk exposure, and the steps management takes to monitor and control such exposure, including our risk assessment and risk management process, guidelines, policies and practices.

Our senior leadership team, which includes Mr. Austin and Ms. Hodges, has established a risk management framework to actively manage, mitigate and report on the various risks faced by Oncor. Pursuant to that framework, as frequently as necessary, but not less than quarterly, our chief risk officer, members of our senior leadership team and additional members of management meet to review and assess various operational, functional, legal and other types of risks facing the company, including risks related to cybersecurity. Discussions at these risk management forums include mitigation strategies and actions to provide oversight and assign responsibility for ongoing treatment and monitoring each specific risk. Risk management information collected at these meetings is then distributed at least quarterly to the Audit Committee of our board of directors as well as our full board of directors. In addition, our chief risk officer reports on these risk management efforts, including risks related to cybersecurity, to the Audit Committee and/or the full board of directors at least quarterly. In addition, Mr. Austin and Ms. Hodges also provide separate written reports on cybersecurity risks and activities to both the Audit Committee and the full board of directors, with specific discussion time devoted to cybersecurity at the Audit Committee and/or the full board of directors at least quarterly.

Item 7.MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis of our financial condition and results of operations for the fiscal years ended December 31, 2023 and 2022 should be read in conjunction with our audited consolidated financial statements and the notes to those statements as well as “Item 1A. Risk Factors.”

Our Annual Report on Form 10-K for the year ended December 31, 2022 includes a discussion and analysis of our financial condition and results of operations for the year ended December 31, 2021 in “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

All dollar amounts in the tables in the following discussion and analysis are stated in U.S. dollars in millions unless otherwise indicated.

BUSINESS

We are a regulated electricity transmission and distribution company that provides the essential service of delivering electricity safely, reliably and economically to end-use consumers through our electrical systems, as well as providing transmission grid connections to merchant generation facilities and interconnections to other transmission grids in Texas. Our transmission and distribution rates are regulated by the PUCT and certain cities, and in certain limited instances, by the FERC. We are not a seller of electricity, nor do we purchase electricity for resale. We are a direct, majority-owned subsidiary of Oncor Holdings, which is indirectly and wholly owned by Sempra. Oncor Holdings owns 80.25% of our membership interests and Texas Transmission owns 19.75% of our membership interests. We are managed as an integrated business; consequently, there is only one reportable segment.

Ring-Fencing Measures

Various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with a direct or indirect ownership interest in Oncor or Oncor Holdings. These ring-fencing measures serve to mitigate the Oncor Ring-Fenced Entities’ credit exposure to Sempra and its affiliates and any other direct or indirect owners of Oncor and Oncor Holdings, and to reduce the risk that the assets and liabilities of the Oncor Ring-Fenced Entities would be substantively consolidated with the assets and liabilities of any Sempra entity or any other direct or indirect owners of Oncor and Oncor Holdings in connection with a bankruptcy of any such entities. Such measures include, among other things: the 19.75% equity interest held by Texas Transmission; maintenance of separate books and records for the Oncor Ring-Fenced Entities; and our board of directors being comprised of a majority of Disinterested Directors. As a result, none of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or obligations of any Sempra entity or any other direct or indirect owner of Oncor or Oncor Holdings. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of any Sempra entities and any other direct or indirect owner of Oncor or Oncor Holdings. We do not bear any liability for debt or contractual obligations of Sempra and its affiliates or any other direct or indirect owner of Oncor or Oncor Holdings, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from Sempra and its affiliates and any other

32

direct or indirect owner of Oncor or Oncor Holdings. For more information on the ring-fencing measures, see “Items 1. and 2. Business and Properties—Ring-Fencing Measures.”

Significant Activities and Events

Base Rate Review (PUCT Docket No. 53601) — On April 6, 2023, the PUCT issued a final order in our comprehensive base rate review proceeding. The base rate review test year was based on calendar year 2021 results with certain adjustments. We estimate that the final order resulted in an average increase over 2021 test year adjusted annualized revenue of 1.4%, and resulted in an aggregate annualized revenue increase over the 2021 test year of approximately $79 million. The final order set our authorized return on equity at 9.7%, a decrease from our prior authorized return on equity of 9.8%. As a result of certain rate base disallowances in the final order, in the first quarter of 2023, we recognized a charge against income for the effects of a $69 million ($54 million after-tax) write-off, consisting of a $55 million ($43 million after-tax) write-off of disallowed capitalized property, plant and equipment reflected in operating expenses and a $14 million ($11 million after-tax) write-off of non-operating disallowances. New rates implementing the terms of the final order went into effect May 1, 2023. In September 2023, we filed an appeal in Travis County District Court requesting judicial review of certain of the rate base disallowances. On February 22, 2024, the court dismissed the appeal. We are currently evaluating whether to appeal that ruling. See “—Regulation and Rates—Matters with the PUCT” below for further discussion of our base rate review proceeding.

Capital Tracker Proceedings — See Note 2 to Financial Statements for a discussion of other significant PUCT matters, including applications for interim DCRF and TCOS rate updates.

State Legislation — See “—Regulation and Rates—State Legislation” below for a discussion of state legislation enacted into law in 2023 that we believe could significantly impact our business, financial condition, and results of operations, including legislation expected to decrease regulatory lag on recovery of certain distribution-related investments, legislation providing greater regulatory certainty on recovery of certain employee compensation and benefit expenses, and legislation permitting utilities to file plans to enhance the resiliency of their transmission and distribution systems, and providing cost recovery mechanisms for such plans.

Debt-Related Activities — See “—Financial Condition—Liquidity and Capital Resources” below, and Notes 5 and 6 to Financial Statements for information regarding our debt-related activities.

KEY FACTORS RELATING TO FUTURE EARNINGS AND RESULTS OF OPERATIONS

Our past earnings and results of operations are not necessarily indicative of our future earnings and results of operations. The magnitude of our future earnings and results of our operations will depend on or be affected by numerous factors including certain key risks and challenges facing management discussed below. For additional information concerning risks related to our business, see “Item 1A. Risk Factors” in this report.

Regulation, Rates and Cost Recovery

The rates we charge for our electricity delivery services are set pursuant to tariffs approved by the PUCT and certain cities and, in the case of transmission service related to limited interconnections to other markets, the FERC. Our rates are subject to regulatory rate-setting processes and earnings oversight. This regulatory treatment does not provide assurance as to achievement of earnings levels or recovery of actual costs. Our rates are based on an analysis of our costs and capital structure in a designated historical test year, as reviewed and approved in a regulatory proceeding. While rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital, there can be no assurance that the PUCT in a base rate review will judge all of our costs, including invested capital and costs included in a regulatory asset reported on the balance sheet, to have been prudently incurred and therefore fully recoverable. For example, the charge against income for the effects of a $69 million ($54 million after-tax) write-off that we recorded in the first quarter of 2023 was due to certain rate base disallowances in our most recent comprehensive base rate review proceeding. The approved levels of recovery could be significantly less than our requested levels, and the approved timing for recovery of regulatory assets could differ from our proposed timelines. There can also be no assurance that the PUCT will approve any other items requested by us in any rate proceeding. For instance, in our most recent comprehensive base rate review, we did not receive our requested capital structure and return on equity. In addition, there is also no assurance that the historical test year regulatory process in which rates are determined will result in rates that will produce full

33

recovery of our actual post-test year costs and/or the full return on invested capital allowed by the PUCT, particularly during periods of increased capital spending, high inflation or increases in general interest rates resulting in increased costs incurred by us relative to our most recent base rate review.

We are required by PUCT rules to file a comprehensive base rate review within four years of the last order in our most recent comprehensive rate proceeding, unless an extension is otherwise approved by the PUCT. However, the PUCT or any city retaining original jurisdiction over rates may direct Oncor to file a base rate review, or Oncor may voluntarily file a base rate review, any time prior to that deadline. Pursuant to these rules, our next comprehensive base rate review is required to be filed by June 2027. The PUCT issued an order in our most recent comprehensive base rate proceeding in April 2023, and rates implementing that order went into effect in May 2023. See “—Regulation and Rates—Matters with the PUCT” for additional discussion on the base rate review.

In between base rate reviews, we are eligible to file interim DCRF and TCOS rate adjustment applications that help shorten the regulatory lag associated with recovery of transmission and distribution investments through regulated rates. These capital trackers allow us to recover, subject to reconciliation, the cost of certain transmission and distribution investments before the investments are considered for prudency in a base rate review. In June 2023, legislation was enacted by the Texas Legislature that increased the number of interim DCRF rate adjustment applications that may be filed by utilities in a single year for certain distribution-related investments from one application to up to two applications per year. Also, under PUCT rules, we can file up to two interim TCOS rate adjustment applications in a calendar year to reflect changes in our invested transmission capital. These interim rate applications are subject to a regulatory proceeding and PUCT approval. Investments included in these capital trackers are also subject to prudence review by the PUCT in the next base rate review following such adjustments, with a potential for the PUCT to also order refunds of previously collected amounts if a particular investment is found to be imprudent or inappropriately included in an interim rate adjustment.

Capital tracker rate adjustment applications include related updates of billing units arising from changes in customer growth and demand, whether positive or negative. Distribution billing units reflect the electricity demand or delivery volumes of our distribution end-use customers and transmission billing units reflect certain changes in average ERCOT-wide peak electricity demand. Regardless of whether a DCRF or TCOS capital tracker is filed, billing unit changes will result in a variation of transmission and distribution base revenues and such changes in annual billing units could mitigate the need to file capital tracker applications. For instance, we anticipate that increased transmission billing units in 2024 as a result of the significant peak load growth in ERCOT during 2023 will result in increased transmission revenues and mitigate the need to file at least one of the two interim TCOS rate adjustment applications we are eligible to file in 2024.

The rate-setting and cost-recovery process is intended to provide revenues to recover the cost of providing electricity delivery service and a return on and recovery of our investment in rate base assets. As a result, management closely monitors our regulatory rate base and the capital expenditure budget which historically has increased our rate base. Our capital expenditure projections through 2028 are largely tied to the expected population growth in our service territory and related increases in residential, commercial and industrial premises, as well as generation interconnections and measures to maintain reliability on the system. The amounts we earn, particularly with respect to retail delivery services, are heavily impacted by the amount of electricity we deliver. Management monitors various drivers that could impact electricity consumption or demand on our system. Such drivers include weather (discussed in more detail below), population and business growth, ERCOT electricity demand growth, number of end use customers, and average customer usage and demand. In recent years Texas has seen increasing population and business growth, and we have experienced an increase in electricity consumption as a result. During 2023, the number of premises (electric points of delivery) increased by 1.9%. We expect the growth in the communities we serve to continue as Texas business and residential growth continues.

Except in certain instances, we are required to file an earnings report annually with the PUCT that includes our estimated regulatory rate base at the end of the previous calendar year. Our regulatory rate base as reported in these filings as of December 31, 2022 and 2021 was $20.7 billion and $18.9 billion, respectively. As calculated on a similar basis, our estimated regulatory rate base at December 31, 2023 was $23.1 billion. The incremental investments included in any calculation of regulatory rate base since the test year in our last base rate review (which test year was 2021 in our most recent base rate review) are subject to PUCT review in our next base rate review.

In addition to rate regulation and earnings oversight as discussed above, our business is subject to numerous other complex governmental regulations and legislation, which has materially impacted our business in the past and could materially impact our business in the future. In addition, public perception regarding us, our industry and our business priorities could influence regulations, administrative actions and legislation. See “Item 1A. Risk Factors—Our business is

34

subject to ongoing complex governmental regulations and legislation that have impacted, and will continue in the future to impact, our business and results of operations.” and “Item 1A. Risk Factors—We are subject to various mandatory regulatory standards and requirements, including with respect to service quality, reliability, and weatherization of facilities. Efforts to comply with those standards could subject us to higher operating costs and/or increased capital expenditures, and non-compliance with applicable standards or expectations could have a material adverse effect on our business.”

See “—Regulation and Rates” below for further information on legislative and regulatory matters.

Weather

Weather is a significant driver of distribution base revenues, as increased cooling and heating needs generally result in higher electricity consumption. As a result, management closely monitors weather and its potential impact on our financial performance. The exact amount of revenue variation due to weather is difficult to measure due to other electricity usage drivers that contribute to revenues. With continued growth in our transmission and distribution system and unusual weather patterns, including those that may be impacted as a result of climate change and other factors, we cannot predict how much the variation to our distribution base revenues due to weather could be in the future. See “—Results of Operations” below for information on volumes of electricity delivered, heating and cooling degree days and a discussion of distribution base revenues and revenues contributing to earnings and “Item 1A. Risk Factors—Our revenues and results of operations are seasonal and significantly impacted by weather events and other electricity usage drivers.”

Significant storms and other emergency events that cause extensive damage on our system or affect electric capacity in the ERCOT market could result in unexpected challenges, including negative public perception, disruptions in our ability to provide electricity delivery services, regulatory and legislative actions, and increased maintenance expenses or capital expenditures. See “Item 1A. Risk Factors—Severe weather, natural disasters, wildfires and other emergency events could adversely impact us” and “Item 1A. Risk Factors—Effects of climate change, including natural disasters, severe weather and other related phenomena, and regulatory and legislative developments related to climate change, including mandatory reporting requirements, may have a material adverse effect on our business, financial condition, results of operations and cash flows” for discussion of the impact of significant storms on our business. Storm related costs are generally recorded as a regulatory asset and our ability to recover any amounts included in those regulatory assets in rates as well as the time period for such recovery is subject to PUCT review and approval.

Capital Availability and Cost

Our business is capital intensive and we expect to rely on access to financial markets as a significant source of funding. Our access to the capital, credit, or commercial paper markets and cost of any such debt could be directly affected by our credit ratings and financial market conditions. Any adverse action with respect to our credit ratings could generally cause borrowing costs to increase and the potential pool of investors and funding sources to decrease. Our credit ratings are currently higher than those of Sempra. If credit rating agencies were to change their views of our independence from Sempra and its affiliates (other than the Oncor Ring-Fenced Entities), our credit ratings could change. We believe this risk is substantially mitigated by the ring-fencing measures as described in Note 1 to Financial Statements. See “Item 1A. Risk Factors—Adverse actions with respect to our credit ratings could negatively affect our cost of debt and our ability to access capital” and “Item 1A. Risk Factors—In the future, we could have capital needs that could be difficult to satisfy under some circumstances, including existing limitations on our ability to incur indebtedness and uncertain financial market conditions.”

In addition, we may be unable to recover in rates some or all of the costs of any such debt financing if they exceed our cost of debt approved by the PUCT in our most recent base rate review or subsequent base rate reviews, which could adversely affect our earnings and cash flows. In 2023, we saw increased borrowing costs due primarily to increases in debt outstanding and to increases in general interest rates. The PUCT-approved cost of debt of 4.39% in our most recent comprehensive base rate review, which was based on a 2021 test year, is reflected in our current base rates and is lower than our actual average cost of debt for the 2023 fiscal year. We do not anticipate a change in our PUCT-approved cost of debt prior to a subsequent base rate review proceeding.

CRITICAL ACCOUNTING ESTIMATES

Our significant accounting policies are discussed in Note 1 to Financial Statements. We prepare our financial statements in accordance with GAAP governing rate-regulated operations. Application of these accounting policies in the preparation of our consolidated financial statements requires management to make estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and revenues and expenses during the periods covered. The following is a summary of certain critical accounting estimates that are impacted by judgments and uncertainties and under which different amounts might be reported using different assumptions or estimation methodologies.

Accounting for the Effects of Certain Types of Regulation

We are subject to rate regulation and our financial statements reflect regulatory assets and liabilities in accordance with GAAP related to the effect of certain types of regulation. Regulatory assets and liabilities represent probable future revenues that will be recovered from or refunded to customers through the ratemaking process based on PURA and/or the PUCT’s orders, precedents or substantive rules. Rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital subject to PUCT review for reasonableness. Regulatory decisions can have an impact on the rate earned on invested capital and the timing and amount of the recovery of assets and other costs through rates. See Note 2 to Financial Statements for more information regarding regulatory assets and liabilities and “—Regulation and Rates—Matters with the PUCT—Base Rate Review (PUCT Docket No. 53601)” below for more information on our base rate review.

Accounting for the Effects of Income Taxes

Our tax sharing agreement with Oncor Holdings, STH and Texas Transmission provides for the calculation of amounts related to income taxes for each of Oncor Holdings and Oncor substantially as if these entities were taxed as corporations and requires payments to the members determined on that basis (without duplication for any income taxes paid by a subsidiary of Oncor Holdings).

We are a partnership for U.S. federal income tax purposes. Accordingly, while partnerships are not subject to income taxes, in consideration of the presentation of our financial statements as an entity subject to cost-based regulatory rate-setting processes with such costs historically including income taxes and the tax sharing agreement, the financial statements present amounts determined under the tax sharing agreement as “provision in lieu of income taxes” and “liability in lieu of deferred income taxes.” Such amounts are determined in accordance with the provisions of the accounting guidance for income taxes and accounting standards that provide interpretive guidance for accounting for uncertain tax positions and thus differences between the book and tax bases of assets and liabilities are accounted for as if we were a stand-alone corporation. In the event such amounts are not paid under the tax sharing agreement, it is probable that this regulatory liability will continue to be included in Oncor’s rate setting processes.

Our expense amounts related to income taxes and related balance sheet amounts are recorded pursuant to our tax sharing agreement, as discussed above. Recording of such amounts involves significant management estimates and judgments, including judgments and estimates of the timing and probability of recognition of income and deductions by taxing authorities. In assessing the likelihood of realization of assets related to income taxes, management considers estimates of the amount and character of future taxable income. Actual amounts related to income taxes could vary from estimated amounts due to the future impacts of various items, including changes in income tax laws, our forecasted financial condition and results of operations in future periods, as well as final review of filed tax returns by taxing authorities. Our income tax returns, as well as the STH Texas margin tax returns in which we are consolidated filers, are regularly subject to examination by applicable tax authorities. In management’s opinion, any liability recorded pursuant to income tax accounting guidance related to uncertain tax positions reflects future amounts that may be owed as a result of any examination. There were no significant changes in estimates or assumptions in the accounting for the effects of income taxes during 2023.

Amounts payable to and receivable from our members related to income taxes on our balance sheet reflect our tax provision net of quarterly estimated tax payments required by the tax sharing agreement that are trued up the following year when the annual tax return is filed.

Impairment of Long-Lived Assets and Goodwill

We evaluate long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. The evaluation of our goodwill and other long-lived assets for which uncertainty exists regarding the recoverability of the carrying value of such assets involves the assessment of future cash flows and external market conditions and other subjective factors that could impact the estimation of future cash flows including, but not limited to, the amount and timing of future cash flows, future growth rates and the discount rate. Unforeseen events and changes in circumstances or market conditions could adversely affect these estimates, which could result in an impairment charge in the event regulatory recovery is not allowed.

We also evaluate goodwill for impairment annually on October 1 and whenever events or changes in circumstances indicate that an impairment may exist. The determination of the existence of these and other indications of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows.

For our annual goodwill impairment testing, we generally have the option to directly perform a quantitative assessment or first make a qualitative assessment of whether it is more likely than not that our estimated enterprise fair value is less than our enterprise carrying value before applying the quantitative assessment. If we elect to perform the qualitative assessment, we evaluate relevant events and circumstances, including but not limited to, macroeconomic conditions, industry and market considerations, cost factors and our overall financial performance. If, after assessing these qualitative factors, we determine that it is more-likely-than-not that our estimated enterprise fair value is less than our enterprise carrying book value, then we perform a quantitative assessment. If, after performing the quantitative assessment, we determine that goodwill is impaired, we record the amount of goodwill impairment as the excess of enterprise carrying book value over estimated enterprise fair value, not to exceed the carrying amount of goodwill.

For our annual goodwill impairment testing as of October 1, 2023, we elected to make a qualitative assessment of whether it is more likely than not that our estimated enterprise fair value is less than our enterprise carrying value. We concluded that our estimated enterprise fair value was more likely than not greater than our enterprise carrying book value. As a result, no quantitative assessment for impairment was required and no impairment was recognized in 2023. For our annual goodwill impairment testing as of October 1, 2022, we elected to perform a quantitative assessment. We estimated our enterprise fair value by weighting results from a market-based approach and an income-based approach. Key assumptions in the valuation methodologies for goodwill included terminal value, discount rates, and comparable multiples from publicly traded companies in our industry. Based on our analysis, we determined that our estimated enterprise fair value was in excess of our enterprise carrying book value, indicating none of our goodwill was impaired and no impairment was recognized in 2022.

Goodwill totaling $4.740 billion was reported on our balance sheet at each of December 31, 2023 and 2022.

Defined Benefit Pension Plans and OPEB Plans

We offer certain pension, health care and life insurance benefits to eligible employees (and certain eligible former employees of our former affiliates whose service was partially assigned to Oncor in connection with the deregulation and disaggregation of the Texas electric market in 2002) and their eligible dependents upon the retirement of such employees as we discuss in Note 9 to Financial Statements. We are authorized to establish a regulatory asset or liability for the difference between the amounts of pension and OPEB costs reflected in our PUCT-approved billing rates and the actual amounts that would otherwise have been recorded as charges or credits to earnings related to recoverable service. Accordingly, we recognize (principally as a regulatory asset or property) additional recoverable pension and OPEB costs consistent with PURA. Net regulatory assets related to our pension and OPEB costs decreased $55 million during 2023. Amounts deferred are ultimately subject to regulatory approval.

Benefit costs are impacted by actual and actuarial estimates of employee demographics (including but not limited to age, compensation levels and years of accredited service), future health care costs, the level of contributions made to retiree plans, expected and actual earnings on plan assets and the discount rates used in determining the projected benefit obligation. Actuarial assumptions are reviewed and updated annually based on current economic conditions and trends. Changes made to the provisions of the plans may also impact current and future benefit costs. Fluctuations in actual equity

37

market returns as well as changes in general interest rates may result in increased or decreased benefit costs in future periods.

In accordance with accounting rules, changes in benefit obligations associated with factors discussed above may be immediately recognized as a regulatory asset if related to recoverable service or in other comprehensive income and reclassified as a current cost in future years. As such, significant portions of benefit costs recorded in any period may not reflect the actual level of cash benefits provided to plan participants.

See Note 9 to Financial Statements regarding other disclosures related to obligations of our pension plans and OPEB plans.

(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.

(c)In general, distribution revenues from residential and small business users are based on actual monthly consumption (kWh), and, depending on size and annual load factor, revenues from large commercial and industrial users are based either on actual monthly demand (kilowatts) or the greater of actual monthly demand (kilowatts) or 80% of peak monthly demand during the prior eleven months.

Financial Results ─ Year Ended December 31, 2023 Compared to Year Ended December 31, 2022

Total operating revenues increased $343 million, or 7%, to $5.586 billion in 2023. Revenue is billed under tariffs approved by the PUCT.

Revenues contributing to earnings increased $204 million to $4.235 billion in 2023. The net increase reflected the following components:

An Increase in Distribution Base Revenues — Distribution base revenues increased $181 million to $2.628 billion in 2023. The increase in distribution base revenues primarily reflects:

o$105 million increase due to a higher distribution-related revenue component in the new base rates implemented May 1, 2023,

o$59 million increase due to updated interim DCRF rates implemented in 2023 to reflect increases in invested capital, and

o$39 million increase due to growth in points of delivery,

Partially offset by

o$24 million decrease due to lower consumption attributable primarily to milder weather.

Distribution base rates are set periodically in a base rate review docket initiated by either us or the PUCT, and effective May 1, 2023, new base rates implementing the final order in PUCT Docket No. 53601 went into effect. PUCT rules allow utilities to file, under certain circumstances, up to two interim DCRF rate adjustment applications per year between comprehensive base rate reviews to recover distribution investments.

See the Interim DCRF Filings Table below for a listing of recent interim DCRF rate adjustment applications impacting revenues for 2023 and 2022, as well as filings anticipated to impact revenues for the year ending December 31, 2024.

(b)Reflects distribution capital investments generally put into service during the period from January 1, 2023 through June 30, 2023.

(c)Reflects distribution capital investments generally put into service during the period from January 1, 2022 through December 31, 2022.

(d)Reflects distribution capital investments generally put into service during the period from January 1, 2020 through December 31, 2020.

An Increase in Transmission Base Revenues — TCOS revenues increased $26 million to $1.498 billion in 2023. The increase in TCOS revenues primarily reflects:

o$60 million increase due to increases in transmission billing units as a result of certain increases in average ERCOT peak-demand, and

o$13 million increase due to updated interim TCOS rates implemented in 2023 to reflect increases in invested capital,

partially offset by

o$ 45 million in lower revenues primarily due to the effects of a lower transmission-related revenue component included in the new base rates implemented May 1, 2023.

TCOS revenues are collected from load serving entities benefitting from our transmission system. REPs serving customers in our service territory are billed through the TCRF mechanism discussed below, while other load serving entities are billed directly. PUCT rules allow utilities to file up to two interim TCOS rate adjustment applications in a calendar year to reflect changes in their invested transmission capital.

40

Transmission billing units are updated to reflect certain changes in average ERCOT-wide peak electricity demand. We anticipate that increases in annual transmission billing units applicable in 2024 will mitigate the need to file at least one of the two interim TCOS rate adjustment applications that we are eligible to file in 2024.

See the Interim TCOS Filings Table below for a listing of recent interim TCOS filings impacting revenues for 2023 and 2022, as well as filings anticipated to impact revenues for the year ending December 31, 2024.

(d)Reflects transmission capital investments generally put into service during the period from January 1, 2021 through June 30, 2021.

A Decrease in Other Miscellaneous Revenues — Other miscellaneous revenues decreased $3 million to $109 million in 2023. The decrease was primarily due to a $7 million decrease in the annual energy efficiency program performance bonus approved in 2023 compared to 2022, offset by higher revenues from discretionary services, including increased facilities studies related to connecting customer facilities to the electric grid, provided in connection with our electricity delivery services pursuant to our tariffs.

Revenues collected for pass-through expenses increased $139 million to $1.351 billion in 2023. While changes in these pass-through tariffs affect revenues and the timing of cash flows, they do not impact operating income and do not contribute to earnings. The increase reflected the following components:

An Increase in TCRF – third-party wholesale transmission service (TCRF Third-Party) — TCRF Third-Party revenues increased $129 million to $1.291 billion in 2023 due to an increase in TCRF Third-Party provider billings.

TCRF is a reconcilable distribution rate charged to REPs to recover fees we pay to TCRF Third-Party providers under their TCOS rates and the retail portion of our own TCOS rate described above. Changes in our TCRF Third-Party revenue are to pass through changes in TCRF Third-Party expense. PUCT rules require us to update the TCRF component of our retail delivery rates on March 1 and September 1 each year, as well as upon implementation of new base rates resulting from a comprehensive base rate review.

41

See the TCRF Filings Table below for a listing of recent TCRF filings impacting revenues for 2023 and 2022, as well as filings anticipated to impact revenues for the year ending December 31, 2024.

52175	May 2021	September 2021 – February 2022	$	149

____________

(a)The TCRF effective March 1, 2023 in Docket No. 54388 was updated as a result of Oncor’s comprehensive base rate review (PUCT Docket No. 53601 and Compliance Docket No. 54817) on May 1, 2023. The base rate case update included a reduction of the revenue requirement to be collected over the six-month period beginning March 2023.

An Increase in EECRF and Other Revenues — EECRF and other revenues increased $10 million to $60 million in 2023. The increase was primarily due to higher EECRF revenues to cover higher energy efficiency program expenses and higher rate case expense rider revenues to cover deferred rate case expense amortization. These revenues were generally offset in operation and maintenance expense.

Other revenues include amounts collected through the rate case expense rider, a reconcilable rate designed to recover rate case expenses approved in our most recent comprehensive rate base review proceeding. EECRF is a reconcilable rate designed to recover current energy efficiency program costs and annual performance bonuses earned by exceeding PUCT targets in prior years and to refund or recover any over/under recovery of our costs in prior years. We recognize the annual performance bonuses in other miscellaneous revenues upon approval by the PUCT. PUCT rules require us to file an annual EECRF tariff update by the first business day in June of each year for implementation on March 1 of the next calendar year.

See the EECRF Filings Table below for a listing of recent EECRF filings impacting revenues for 2023 and 2022, as well as filings that will impact revenues for the year ending December 31, 2024.

EECRF Filings Table

PUCT Docket No.	Filed	Effective	Monthly Charge per Residential Customer (a)		Program Costs		Performance Bonus		(Over)-/ Under- Recovery and Other
55074	May 2023	March 2024	$	1.23	$	49	$	21	$	2
53671	May 2022	March 2023	$	1.23	$	52	$	28	$	3

50886	May 2020	March 2021	$	1.03	$	53	$	14	$	(2)

____________

(a)Monthly charges are for a residential customer using an assumed 1,200 kWh.

Wholesale transmission service expense increased $129 million to $1.291 billion in 2023. The increase was due to higher fees paid to third-party transmission entities. Wholesale transmission service expense is a reconcilable expense that is offset with TCRF Third-Party revenues as discussed above.

Operation and maintenance expense increased $95 million to $1.150 billion in 2023. The increase was primarily due to $56 million in higher regulatory assets amortization (including $4 million related to amortization of expenses incurred for our most recent comprehensive base rate review), a $32 million increase in the accrual recovery amount for our self-insurance reserve as a result of the new base rates that went into effect on May 1, 2023 (which new rates

42

implemented a five-year regulatory asset amortization period for certain regulatory assets and an increased annual accrual recovery amount for our self-insurance reserve pursuant to the PUCT’s final order in our comprehensive base rate review), $11 million in higher labor and contractor related costs and $5 million in higher energy efficiency program expenses, partially offset by $8 million in lower vegetation management costs. We expect to continue to experience higher operation and maintenance expenses, including amounts related to labor and contractor costs.

Depreciation and amortization increased $74 million to $978 million in 2023. The increase was primarily attributable to ongoing investments in property, plant and equipment and higher depreciation and amortization rates as a result of implementing the final order in PUCT Docket No. 53601 in 2023.

Provision in lieu of income taxes netted to $177 million (including an $8 million benefit related to non-operating income) in 2023 compared to $191 million (including a $10 million benefit related to non-operating income) in 2022. The decrease is primarily due to the decrease in net income driven in part by the tax benefits associated with the write-off of rate base disallowances in the first quarter of 2023.

The effective income tax rate was 17.0% and 17.4% for 2023 and 2022, respectively. The effective tax rate on pretax income differs from the U.S. federal statutory rate of 21% primarily due to the amortization of the regulatory liability for excess deferred taxes as a result of the Federal Tax Cuts and Jobs Act of 2017 and the research and development credits resulting from filing amended federal income tax returns for 2019 through 2021, partially offset by the effects of the Texas margin tax.

Taxes other than amounts related to income taxes decreased $9 million to $552 million in 2023. The decrease was primarily due to lower property taxes attributable to lower property tax rates enacted by the Texas Legislature in 2023, partially offset by increases in local franchise taxes payable by us to municipalities.

Other (income) and deductions - net was $51 million favorable in 2023 compared to 2022. The variance was primarily due to $24 million in lower reconcilable employee retirement benefit expense, which was offset in operating revenues, a $15 million favorable change in the value of certain compensation plan rabbi trust assets, which was generally offset in compensation expense and $14 million higher AFUDC – equity income.

Interest expense and related charges increased $91 million to $536 million in 2023. The increase was primarily due to higher average borrowings attributable to ongoing investments in property, plant and equipment and higher average interest rates on the borrowings.

Write-off of rate base disallowances was recorded in the amount of $69 million in the first quarter of 2023, as a result of the final order issued by the PUCT in April 2023 in our comprehensive base rate review, which excluded from rate base certain employee benefit and compensation related costs. The write-off includes a $55 million ($43 million after-tax) write-off of disallowed capitalized property, plant and equipment reflected in operating expenses and a $14 million ($11 million after-tax) write-off of non-operating disallowances related to these disallowed employee benefit and compensation related costs. See Note 2 to Financial Statements for more information.

Net income decreased $41 million to $864 million in 2023. The decrease was driven by:

higher costs associated with increases in invested capital (primarily borrowing costs and depreciation),

higher operation and maintenance expense, and

the write-off of rate base disallowances recorded in the first quarter of 2023 resulting from the PUCT’s final order in our comprehensive base rate review,

partially offset by

higher revenues primarily attributable to:

oupdated interim rates to reflect increases in invested capital,

oincreases in transmission billing units as a result of certain increases in average ERCOT peak demand,

othe new base rates implemented May 1, 2023, and

ocustomer growth.

43

OTHER COMPREHENSIVE (LOSS) INCOME

During the first quarter of 2023, we reclassified $20 million related to certain employee retirement liabilities previously recorded in regulatory assets to other comprehensive income, as a result of the final order in our comprehensive base rate review disallowing rate recovery of those costs.

In November 2023, we entered into interest rate hedge transactions hedging the variability of benchmark bond rates used to determine the interest rates on the anticipated issuance of ten-year senior secured notes. The hedges were terminated in November 2023 upon the issuance of our 5.65% Senior Secured Notes due November 15, 2033, and a $4 million ($3 million after-tax) loss was reported in other comprehensive income. We expect approximately $3 million of the amount reported in accumulated other comprehensive loss at December 31, 2023 related to the November 2023 interest rate hedges, as well as interest rate hedges from prior years, to be reclassified into net income as an increase to interest expense within the next 12 months.

(a)Issued under a note purchase agreement entered into on March 29, 2023 (March 2023 NPA) with the purchasers named therein.

(b)Issued under an existing indenture.

Our fixed rate senior secured notes are secured equally and ratably by a first priority lien on all property acquired or constructed by Oncor for use in our electricity transmission and distribution business, subject to certain exceptions. The property is mortgaged under the Deed of Trust. The Deed of Trust permits us to secure indebtedness with the lien of the Deed of Trust up to the aggregate of (i) the amount of available bond credits, and (ii) 85% of the lower of the fair value or cost of certain property additions that could be certified to the Deed of Trust collateral agent. At December 31, 2023, the amount of available bond credits was $2.585 billion and the amount of future debt we could secure with property additions, subject to those property additions being certified to the Deed of Trust collateral agent, was $4.928 billion. See Note 6 to Financial Statements for a listing of all of our fixed rate senior notes secured by the Deed of Trust.

AR Facility — On April 28, 2023, Oncor and Receivables LLC established the AR Facility, a three-year $500 million revolving accounts receivable securitization facility secured by accounts receivable from REPs and related rights. Oncor has access to the AR Facility, under which Receivables LLC may borrow at any one time an amount equal to the borrowing base. The borrowing base is defined under the receivables financing agreement as an amount equal to the lesser of (i) the facility limit of $500 million and (ii) the amount calculated based on the outstanding balance of eligible REP receivables held as collateral at a particular time, subject to certain reserves, concentration limits, and other limitations.

At December 31, 2023, the borrowing base for the AR Facility was $500 million and no borrowings were outstanding under the AR Facility.

The following table summarizes the borrowings and repayments under our AR Facility from its April 28, 2023 inception date through December 31, 2023:

	Amounts
Aggregate borrowings (a)	$	600
Aggregate repayments		(600)
Balance at December 31, 2023	$	-

(a)Borrowings under the AR Facility bore interest at the daily cost of asset-backed commercial paper issued by the conduit lenders to fund the loans, plus related dealer commissions and note issuance costs. Additional borrowings under the AR Facility could bear interest, if funded by the committed lenders, at a rate per annum equal to SOFR calculated based on term SOFR for a one-month interest period, plus an adjustment of 0.10% (the SOFR Adjustment). Receivables LLC also pays a used and unused fee in connection with the AR Facility.

____________

(a)Borrowings under this unsecured term loan credit agreement, which was entered into January 24, 2023, bore interest at a rate per annum equal to SOFR calculated based on term SOFR for a one-month interest period as of a specified date, plus the SOFR Adjustment, plus a spread of 0.85%.

(b)Borrowings under this unsecured term loan credit agreement, which was entered into March 22, 2023, bore interest at a rate per annum equal to SOFR calculated based on term SOFR for a one-month interest period as of a specified date, plus a spread of 0.95%.

(c)Borrowings under this unsecured term loan credit agreement, which was entered into July 6, 2022 (July 2022 Term Loan Credit Agreement), bore interest at a rate per annum equal to SOFR calculated based on term SOFR for a one-month interest period as of a specified date, plus the SOFR Adjustment plus a spread of 0.60%.

Long-Term Debt-Related Activities in 2024

Subsequent Borrowings under AR Facility

On January 30, 2024, we borrowed $300 million aggregate principal amount under the AR Facility.

$500M Credit Facility

On February 21, 2024, we entered into our new unsecured revolving $500M Credit Facility. The $500M Credit Facility has a borrowing capacity of $500 million and a maturity date of February 21, 2027. The $500M Credit Facility gives us the option to request an increase in our borrowing capacity of up to $500 million in $100 million minimum increments, subject to certain conditions, including lender approvals. The $500M Credit Facility also provides us with the option to request that each lender extend the term of its commitment for up to two additional one-year periods, subject to certain conditions, including lender approvals. See Note 6 to Financial Statements for more information on the $500M Credit Facility.

On February 23, 2024, we submitted an irrevocable borrowing request under the $500M Credit Facility for a $220 million borrowing to be made on February 28, 2024. We intend to use the proceeds from the borrowing for general corporate purposes, including to repay outstanding CP Notes. Following the borrowing, $280 million will be available for future borrowings under the $500M Credit Facility.

47

Short-Term Debt-Related Activities in 2023

Our unsecured revolving $2B Credit Facility has a borrowing capacity of $2.0 billion and a maturity date of November 9, 2028. We have the option to request an increase in our borrowing capacity of up to $400 million in $100 million minimum increments, subject to certain conditions, including lender approvals. The $2B Credit Facility includes sustainability-linked pricing metrics related to specific environmental and employee health and safety sustainability objectives.

We have also established a CP Program, under which we may issue unsecured CP Notes on a private placement basis up to a maximum aggregate amount outstanding at any time of $2.0 billion and with maturity dates not exceeding 397 days from the date of issuance. To the extent any CP Notes are issued with maturity dates of over one year, we anticipate those would be classified as long-term debt. The CP Program obtains liquidity support from the $2B Credit Facility. As a result, the aggregate principal amount outstanding under both the CP Program and the $2B Credit Facility cannot exceed $2.0 billion.

As of December 31, 2023 and December 31, 2022, we had $282 million and $198 million of CP Notes outstanding, respectively. The weighted average interest rate for CP Notes was 5.54% and 4.58% at December 31, 2023 and December 31, 2022, respectively. All outstanding CP Notes at December 31, 2023 and December 31, 2022 had maturity dates of less than one year.

See Note 5 to Financial Statements for additional information regarding the $2B Credit Facility and CP Program.

Available Liquidity and Liquidity Needs, Including Capital Expenditures

Capital Expenditures — Our board of directors has approved a capital expenditures budget of approximately $4.5 billion for 2024. We currently contemplate that our aggregate capital expenditures plan over the five-year period 2024-2028 will total approximately $24.2 billion, plus additional amounts attributable to capital expenditures associated with system resiliency plans pursuant to Texas House Bill 2555 and related rules promulgated by the PUCT. System resiliency plans are required to cover a minimum three-year period, and we currently target filing our first three-year system resiliency plan with the PUCT in the first half of 2024. Texas House Bill 2555 contemplates that the PUCT will review and approve, modify, or deny a filed plan within 180 days. See “— Regulation and Rates—State Legislation” below for more information on Texas House Bill 2555.

The increase in our five-year capital plan compared to our prior five-year capital plan is due primarily to continued projected growth and expansion of our system, particularly on the transmission side of our business as a result of the large volume of customer interconnection requests and generator interconnection requests that we have received through 2023 and expect to continue to receive. The increase is also partially driven by price increases of materials due to tightening supply chains. We anticipate cost increases related to materials to continue over time due to constrained supply and increasing demand. Our increased capital plan also reflects continued anticipated cost increases relating to labor and contractor costs. In addition, we also anticipate significant potential capital investment opportunities incremental to our five-year capital plan may be available as a result of continued growth in ERCOT, particularly on the transmission side of our business due to increased customer demand, and additional distribution-related reliability and resiliency needs. 

Long-Term Debt Maturities and Interest — As of December 31, 2023, our obligations related to long-term debt and related interest payments are as follows:

	2024		2025		2026		2027		2028		Thereafter		Total
Principal amounts	$	500	$	974	$	238	$	-	$	1,250	$	10,483	$	13,445
Interest payments		571		556		537		533		514		5,945		8,656
Total	$	1,071	$	1,530	$	775	$	533	$	1,764	$	16,428	$	22,101

See Note 6 to Financial Statements for more information regarding long-term debt.

Pension Plans and OPEB Plans Funding — Based on funding considerations in the latest actuarial projections, including applicable minimum funding requirements, our future funding for the pension plans and the OPEB Plans is

48

expected to total $91 million and $23 million, respectively, in 2024 and approximately $549 million and $135 million, respectively, in the five-year period 2024 to 2028. Future funding estimates for our pension plans and OPEB Plans are dependent on a variety of variables and assumptions, including investment returns on plan assets, market interest rates, and levels of discretionary contributions over minimum funding requirements, which we continue to monitor. Financial market volatility and its effects on the returns on our plan assets and liability valuations could significantly change our anticipated future funding amounts. We may also elect to make additional discretionary contributions based on market and/or business conditions. In 2023, we made cash contributions to the pension plans and OPEB Plans of $5 million and $24 million, respectively. See Note 9 to Financial Statements for additional information regarding pension plans and OPEB Plans.

Additional Liquidity Needs — In addition to the items discussed above, other material contractual obligations and commitments arising in the normal course of business primarily consist of purchase obligations under outsourcing agreements and operating lease obligations. See Note 7 to Financial Statements for information regarding leases. As of December 31, 2023, our purchase obligations under outsourcing agreements total $142 million in the five-year period from 2024 to 2028. In addition, we regularly evaluate opportunities to make selective strategic acquisitions involving regulated assets, which could potentially impact our liquidity and capital expenditures. See “Item 1A. Risk Factors—We regularly evaluate opportunities to make selective strategic acquisitions involving regulated assets. Acquisitions involve various risks, and we may not be able to realize the anticipated benefits of any such acquisitions.”

Available Liquidity — Our primary source of liquidity, aside from operating cash flows, is our ability to issue CP Notes and borrow under our Credit Facilities and AR Facility. The following table summarizes available liquidity at December 31, 2023 and 2022:

	At December 31,				Increase
	2023		2022		(Decrease)
Cash and cash equivalents	$	19	$	10	$	9
Available unused credit under the $2B Credit Facility and CP Program		1,718		1,802		(84)
Available borrowing capacity under AR Facility (a)		500		-		500
Available liquidity – Total (b)	$	2,237	$	1,812	$	425

____________

(a)On January 30, 2024, we borrowed $300 million aggregate principal amount under the AR Facility.

(b)On February 21, 2024, we entered into our new $500M Credit Facility. On February 23, 2024, we submitted an irrevocable borrowing request under the $500M Credit Facility for a $220 million borrowing to be made on February 28, 2024.

We expect cash flows from operations combined with long-term debt issuances and credit agreements as well as availability under our existing Credit Facilities, the CP Program and the AR Facility to be sufficient to fund current obligations, projected working capital requirements, maturities of long-term debt, capital expenditures, minimum funding requirements for pension plans and OPEB Plans, operating lease obligations and purchase obligations under outsourcing agreements for at least the next twelve months. Should additional liquidity or capital requirements arise, we may need to seek member capital contributions or preserve equity through reductions or suspension of distributions to members. In addition, we may also consider repurchases, exchange offers, accounts receivable financing arrangements, and other transactions in order to refinance or manage our debt and manage our liquidity and capital requirements.

Over both the short term and the long term, we expect to rely on access to financial markets as a significant source of funding not satisfied by cash-on-hand, operating cash flows, or our Credit Facilities, CP Program and AR Facility. The inability to raise capital on favorable terms or failure of counterparties to perform under credit or other financial agreements, particularly during any uncertainty in the financial markets, could impact our ability to sustain and grow the business and would likely increase capital costs that may not be fully recoverable through rates. See “Item 1A. Risk Factors—Market volatility may impact our business and financial condition in ways that we currently cannot predict.”

Capitalization and Return on Equity

The PUCT has the authority to determine what types of debt and equity are included in a utility’s debt-to-equity ratio. For purposes of this ratio, debt is calculated as long-term debt including any finance leases plus unamortized gains on reacquired debt less unamortized issuance expenses, premiums and losses on reacquired debt. Equity is calculated as

49

membership interests determined in accordance with GAAP, excluding accumulated other comprehensive loss and the effects of acquisition accounting from a 2007 transaction.

We have committed to the PUCT to maintain a regulatory capital structure at or below the debt-to-equity ratio established periodically by the PUCT for ratemaking purposes. Our current authorized regulatory capital structure is 57.5% debt to 42.5% equity. At December 31, 2023, our regulatory capitalization was 55.8% debt to 44.2% equity. Our authorized return on equity is 9.7%, which went into effect on May 1, 2023 in connection with the effectiveness of new base rates implementing the terms of the PUCT’s final order in PUCT Docket No. 53601. Prior to May 1, 2023, our authorized return on equity was 9.8%. Our ability to incur additional long-term debt is limited by our authorized regulatory capital structure, as we are able to issue future long-term debt only to the extent that the issuance of such debt would not cause us to exceed the authorized regulatory debt-to-equity ratio.

Our GAAP capitalization ratios were 48.3% debt to 51.7% equity and 45.3% debt to 54.7% equity at December 31, 2023 and 2022, respectively.

Member Contributions and Distributions

Contributions — On February 16, 2024, we received cash capital contributions from our members totaling $240 million. During 2023, we received the following cash capital contributions from our members:

Receipt Dates	Amounts
February 13, 2023	$	106
April 27, 2023	$	115
July 27, 2023	$	115
October 26, 2023	$	116

Distributions — The Sempra Order and our LLC Agreement set forth various restrictions on distributions to our members. Among those restrictions is the commitment that we will make no distributions (other than contractual tax payments) to our members that would cause us to exceed our debt-to-equity ratio authorized by the PUCT. The distribution restrictions also include the ability of a majority of our Disinterested Directors, or either of the two member directors designated by Texas Transmission, to limit distributions to the extent each determines it is necessary to meet expected future requirements of Oncor (including continuing compliance with the PUCT debt-to-equity ratio commitment). At December 31, 2023, we had $714 million available to distribute to our members.

On February 14, 2024, our board of directors declared a cash distribution of $125 million, which was paid to our members on February 15, 2024. During 2023, our board of directors declared, and we paid, the following cash distributions to our members:

Declaration Dates	Payment Dates		Amounts
February 14, 2023	February 15, 2023	$	106
April 25, 2023	April 26, 2023	$	149
July 25, 2023	July 26, 2023	$	149
October 24, 2023	October 25, 2023	$	148

Credit Rating Provisions and Material Debt Covenants

Impact on Liquidity of Credit Ratings — The rating agencies assign credit ratings to certain of our debt securities. Our access to capital markets and cost of debt could be directly affected by our credit ratings. Any adverse action with respect to our credit ratings could generally cause borrowing costs to increase and the potential pool of investors and funding sources to decrease. In particular, a decline in credit ratings would increase the cost of our Credit Facilities (as discussed below). In the event any adverse action with respect to our credit ratings takes place and causes borrowing costs to increase, we may not be able to recover such increased costs if they exceed our PUCT-approved cost of debt determined in our most recent comprehensive base rate review or subsequent base rate reviews.

Most of our large suppliers and counterparties require an expected level of creditworthiness in order for them to enter into transactions with us. If our credit ratings decline, the costs to operate our business could increase because

50

counterparties could require the posting of collateral in the form of cash-related instruments, or counterparties could decline to do business with us.

Presented below are the credit ratings assigned for our debt securities at February 27, 2024.

Credit Rating Agency	Senior Secured	Commercial Paper
S&P	A+	A-1
Moody’s	A2	Prime-2
Fitch	A	F2

A rating reflects only the view of a rating agency, and is not a recommendation to buy, sell or hold securities. Ratings can be revised upward or downward at any time by a rating agency if such rating agency decides that circumstances warrant such a change.

Material Debt Credit Rating, Financial, and Cross-Default Covenants — Each of our Credit Facilities contains terms pursuant to which the interest rates and commitment fee charged under the agreement may be adjusted depending on our credit ratings. A decline in our credit ratings would increase the cost of borrowings and the commitment fees on undrawn amounts under our Credit Facilities and likely increase the cost of our CP Program and any future debt issuances and additional credit facilities. Based on our current debt ratings as of February 27, 2024, under each Credit Facility the commitment fee will be 0.10% and the applicable margin for SOFR-based borrowings would be 1.00% and alternate base rate borrowings would be 0.00%. The CP Program requires prompt notice to the dealers of any notice of intended or potential downgrade of our credit ratings. See Note 5 to Financial Statements for additional information regarding our each of our Credit Facilities and CP Program.

The $2B Credit Facility includes sustainability-linked pricing metrics related to specific environmental and employee health and safety sustainability objectives. The $2B Credit Facility provides that the applicable margin and commitment fee may be increased, decreased or have no change depending on our annual performance on the two sustainability-linked pricing metrics. Based on our 2023 performance on those two sustainability-linked pricing metrics in 2023, in which we met the employee health and safety target, but due to supply chain constraints were unable to meet the environmental threshold objective of securing a certain number of lower-emissions bucket trucks, we anticipate an increase to the applicable margin and commitment fee during 2024 of +.005% and +.025%, respectively. The maximum pricing adjustment in any given year is +/- 0.01% on the commitment fee and +/- 0.05% on the applicable margin.

Our Credit Facilities, AR Facility, and note purchase agreements each contain a financial covenant that requires maintenance of a consolidated senior debt-to-capitalization ratio of no greater than 0.65 to 1.00. For purposes of this ratio, senior debt is calculated as indebtedness defined in the applicable agreement (principally, the sum of long-term debt, any capital leases (referred to as finance leases under current accounting literature), short-term debt and debt due currently in accordance with GAAP). Capitalization under the Credit Facilities, the AR Facility and the March 2023 NPA is calculated as membership interests determined in accordance with GAAP plus debt described above. Capitalization under our note purchase agreement dated May 6, 2019 (May 2019 NPA) is calculated as membership interests plus liabilities for indebtedness maturing more than 12 months from the date of determination, with capitalization determined in accordance with GAAP and practices applicable to our type of business. The ratio under the May 2019 NPA is calculated as total debt (all debt of Oncor and its subsidiaries on a consolidated basis) divided by the sum of total debt plus capitalization. At December 31, 2023, we were in compliance with this covenant and all other covenants under the $2B Credit Facility, AR Facility, and note purchase agreements.

Certain of our financing arrangements contain provisions that may result in an event of default if there was a failure under other financing arrangements to meet payment terms or to observe other covenants that could result in an acceleration of payments due. Such provisions are referred to as “cross default” provisions.

Under the Credit Facilities, May 2019 NPA and the AR Facility, a default by us or any subsidiary in respect of indebtedness in a principal amount in excess of $100 million or any judgments for the payment of money in excess of $100 million that are not discharged or stayed within 60 days may cause the maturity of outstanding balances under those facilities to be accelerated or, in the case of the May 2019 NPA, may cause the notes issued thereunder to be declared due and payable.

51

Under the Deed of Trust, an event of default under our indentures or, after all applicable notices have been given and all applicable grace periods have expired, under the note purchase agreements, would permit the holders of our secured debt under the indentures or the note purchase agreements to exercise their remedies under the Deed of Trust.

Guarantees

At December 31, 2023, we did not have any material guarantees.

COMMITMENTS AND CONTINGENCIES

CHANGES IN ACCOUNTING STANDARDS

See Note 1 to Financial Statements for discussion of changes in accounting standards.

REGULATION AND RATES

Matters with the PUCT

Base Rate Review (PUCT Docket No. 53601) — On April 6, 2023, the PUCT issued a final order in our comprehensive base rate review filed in May 2022 with the PUCT and the cities in our service territory that have retained original jurisdiction over rates. New base rates implementing the final order went into effect on May 1, 2023. The base rate review test year was based on calendar year 2021 results with certain adjustments. We estimate that the final order results in an average increase over 2021 test year adjusted annualized revenue of 1.4%, and would result in an aggregate annualized revenue increase over the 2021 test year of approximately $79 million. Key findings made by the PUCT in the final order include setting our authorized return on equity at 9.7% (a decrease from our prior authorized return on equity of 9.8%), maintaining our regulatory capital structure at 57.5% debt to 42.5% equity, approving our requested regulatory asset amortization period of five years, changing depreciation rates and lives of certain depreciable assets, and approving our requested increase for our annual self-insurance reserve accrual primarily associated with storm related costs. In addition, the final order excluded from rates an acquisition premium and its associated amortization costs relating to certain plant facilities acquired by Oncor in 2019, as well as certain employee benefit and compensation related costs that we had previously capitalized during the period of 2017 through 2021. As a result, we recognized a $69 million ($54 million after-tax) write-off in the three months ended March 31, 2023 for the effects of that disallowance, including an additional charge against income due to certain similar employee benefit and compensation related costs that were capitalized during 2022.

On June 30, 2023, the PUCT issued an order on rehearing in response to the motions for rehearing filed by us and certain intervening parties in the proceeding. The order on rehearing made certain technical and typographical corrections to the final order, but otherwise affirmed the material provisions of the final order and did not require modification of the rates that went into effect on May 1, 2023. On September 22, 2023, we filed an appeal in Travis County District Court. The appeal sought judicial review of certain of the order on rehearing’s rate base disallowances (the disallowed 2019 acquisition premium and its associated amortization costs as well as certain of the disallowed employee benefit and compensation related costs that we had previously capitalized) and related expense effects of those disallowances. On February 22, 2024, the court dismissed the appeal for lack of jurisdiction. We are currently evaluating whether to appeal that ruling.

Capital Trackers— See Note 2 to Financial Statements for a discussion of interim DCRF and TCOS rate adjustment applications.

State Legislation

The Texas Legislature operates under a biennial system and meets in regular session in every odd-numbered year and during special sessions called by the Governor of Texas. The Texas Legislature convened its regular session in January 2023, which concluded May 29, 2023, and in 2023 the Governor of Texas called four special sessions following the end of the regular session.

52

During any regular or special session, the Texas Legislature may hold hearings relevant to our business and bills may be introduced that, if adopted, could materially and adversely affect our business and our business prospects.

In 2023, the Texas Legislature passed various legislation impacting the electric industry, including the following bills that have now been enacted into law that we anticipate could have a significant impact on our business, financial condition, and results of operations, particularly through reduction of regulatory lag and increased regulatory certainty regarding recovery of certain costs:

Senate Bill 1015 allows utilities to file up to two interim DCRF rate update applications each year at any time during the year (with certain exceptions if a base rate proceeding is pending) and shortens the administrative process for the proceedings to 60 days, which deadline the PUCT may extend by up to an additional 15 days. Prior to this legislation taking effect, utilities were only permitted to file one DCRF application per year, and were required to make that filing during the first eight days of April (unless otherwise extended by the PUCT). In addition, utilities were previously not permitted to file an interim DCRF rate update application during, or within a certain number of days before, a base rate proceeding. The legislation permits filing an application during a base rate proceeding, provided that filing is made at least 185 days after the commencement of the base rate proceeding. As a result of Senate Bill 1015, we were able to file two interim DCRF rate update applications during 2023. See “—Results of Operations—Financial Results—Year Ended December 31, 2023 Compared to Year Ended December 31, 2022—Interim DCRF Filings Table” for more information on the interim DCRF rate update applications filed in 2023.

Senate Bill 1016 creates a presumption that employee compensation and benefit costs (other than pension, OPEBs, or certain incentive compensation for officers) are reasonable and necessary if the costs are consistent with market compensation studies issued within three years of the rate proceeding.

House Bill 2555 authorizes an electric utility, following rulemaking proceedings by the PUCT, to file for approval of a plan to increase the resiliency of its transmission and distribution system and provides recovery options for certain of those costs, including through deferral to regulatory assets. The bill requires that the PUCT finalize rules to implement the legislation, and the PUCT has opened a rulemaking proceeding for that purpose in PUCT Project No. 55250. The PUCT adopted rules to implement the legislation in January 2024 that, among other things, outline the required elements of a resiliency plan and details of the cost recovery options. Under the rules adopted by the PUCT, implementation of a resiliency plan is subject to review and approval by the PUCT. Utilities may also apply for a specific rider to recover certain resiliency-related costs in rates, or, upon approval of a plan, utilities may defer as a regulatory asset all or a portion of distribution-related resiliency costs, including depreciation expense and carrying costs of resiliency-related distribution capital and other distribution costs, with recovery of the regulatory asset through the interim DCRF rate adjustment mechanism or a base-rate proceeding. Implementation of a resiliency plan is subject to review and approval or modification of the specific plan by the PUCT. We are targeting filing a system resiliency plan for PUCT approval in the first half of 2024 and, upon approval of a plan, intend to defer as a regulatory asset distribution-related resiliency costs as permitted by the rules.

Other state legislation enacted recently that could impact our business and operations include legislation reducing property taxes, legislation shortening the time period for certain approvals relating to transmission projects, legislation expanding and clarifying the uses of mobile generation leased by utilities for use during power outages, and legislation directing ERCOT and the PUCT to develop plans for transmission projects to serve certain high growth areas of the state, including the Permian Basin.

Summary

We cannot predict future regulatory or legislative actions or any changes in economic and financial market conditions. Such actions or changes could significantly alter our financial position, results of operations, or cash flows.

Item 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk

Market risk is the risk that we may experience a loss in value as a result of changes in market conditions such as interest rates that occur in the ordinary course of business. From time to time, we transact in financial instruments to hedge interest rate risk related to our forecasted issuances of debt. There were no such hedges in place at December 31, 2023 or

53

December 31, 2022. For information on the interest rate hedges we entered into and terminated in November 2023, see Note 6 to Financial Statements.

At December 31, 2023, all of our long-term debt carried fixed interest rates. At December 31, 2022, all of our long-term debt, other than the July 2022 Term Loan Credit Agreement borrowings, carried fixed interest rates. The following table presents our long-term debt maturities and related information.

	Expected Maturity Date
	2024		2025		2026		2027		2028		There-after		2023 Total Carrying Amount		2023 Total Fair Value		2022 Total Carrying Amount		2022 Total Fair Value
	(dollars in millions and percent)
Long-term debt (including current maturities):
Fixed rate debt amount (a)	$	500	$	974	$	238	$	-	$	1,250	$	10,483	$	13,445	$	12,798	$	11,245	$	10,398
Weighted average interest rate (b)		1.15%		2.00%		5.24%		-		3.99%		4.61%		4.25%		-		4.15%		-

____________

(a)Excludes unamortized premiums, discounts and debt issuance costs. See Note 6 to Financial Statements for a discussion of changes in long-term debt obligations.

(b)Based on annualized interest rates for each outstanding series of fixed rate notes.

(c)On January 9, 2023, we repaid the remaining $100 million principal amount outstanding under the July 2022 Term Loan Credit Agreement. At the time of repayment and as of December 31, 2022, the interest rate on this variable rate debt was 5.02%.

Borrowings of short-term debt under the Credit Facilities bear interest on a floating rate basis. At December 31, 2023 and December 31, 2022, there were no borrowings outstanding under the $2B Credit Facility. Borrowings under the AR Facility also bear interest on a floating rate basis. At December 31, 2023, no borrowings were outstanding under the AR Facility. On January 30, 2024, we borrowed $300 million aggregate principal amount under the AR Facility. On February 23, 2024, we submitted an irrevocable borrowing request under the $500M Credit Facility for a $220 million borrowing to be made on February 28, 2024.

At December 31, 2023, we had no floating rate debt outstanding. Based on the amount of floating rate debt outstanding as of December 31, 2022, a hypothetical 100 basis point change (up or down) in interest rates would not have a material impact on our results of operations or financial condition. For more information on our borrowings and interest rates charged, see Notes 5 and 6 to Financial Statements.

Credit Risk

Credit risk relates to the risk of loss associated with nonperformance by counterparties. Our distribution business customers consist primarily of REPs. As a prerequisite for obtaining and maintaining certification, a REP must meet the financial resource standards established by the PUCT. Meeting these standards does not guarantee that a REP will be able to perform its obligations. REP certificates granted by the PUCT are subject to suspension and revocation for significant violation of PURA and PUCT rules. Significant violations include failure to timely remit payments for invoiced charges to a transmission and distribution utility pursuant to the terms of tariffs approved by the PUCT. We believe PUCT rules that allow for the recovery of uncollectible amounts due from REPs through rates significantly reduce our credit risk. At December 31, 2023 and December 31, 2022, we had accrued $7 million and $8 million, respectively, in a regulatory asset with respect to amounts deemed uncollectible from REPs.

54

Our exposure to credit risk associated with accounts receivable totaled $958 million and $897 million at December 31, 2023 and December 31, 2022, respectively. The accounts receivable balance is before the allowance for uncollectible accounts, which totaled $14 million and $13 million at December 31, 2023 and December 31, 2022, respectively. The exposure at December 31, 2023 and December 31, 2022 includes accounts receivable from REPs totaling $640 million and $587 million, respectively, which are generally noninvestment grade, and from transmission customers totaling $157 million and $31 million at December 31, 2023 and December 31, 2022, respectively, which primarily include investment grade distribution companies, as well as cooperatives and municipally-owned utilities, which are generally considered low credit risk. The accounts receivable balance from REP subsidiaries of Vistra and NRG Energy, Inc., our two largest customers, collectively represented 22% and 20%, respectively, of our accounts receivable balance at December 31, 2023 and 23% and 20%, respectively, of our accounts receivable balance at December 31, 2022. No other customers during such periods represented 10% or more of the total accounts receivable balance. We view our exposure to these customers to be within an acceptable level of risk tolerance considering PUCT rules and regulations; however, this concentration increases the risk that a default could have a material effect on cash flows, liquidity, financial position and/or results of operation.

Our net exposure to credit risk associated with accounts receivable from affiliates was zero at both December 31, 2023 and 2022.

In the ordinary course of our business, we may also mitigate risk by requiring counterparties to provide us with security. For instance, we require customers who do not meet certain credit quality thresholds to provide security before we commence construction on certain customer-requested construction projects for generation interconnection or new/expanded electricity delivery system facilities. This process helps us to mitigate the risk of our expending funds on construction projects that are not put into service due to customer cancellation of the project. Customers may provide the required security in the form of cash, letters of credit, or, at Oncor’s discretion, through a parent/affiliate guaranty. Such customer-provided security is subject to return in accordance with PUCT rules, ERCOT requirements or our tariffs, and any cash received as such security is held in an escrow account and classified as restricted cash.

Item 8.FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Members of Oncor Electric Delivery Company LLC

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Oncor Electric Delivery Company LLC and subsidiaries (the “Company”) as of December 31, 2023 and 2022, the related consolidated statements of income, comprehensive income, cash flows, and membership interests, for each of the three years in the period ended December 31, 2023, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company’s internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated February 27, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Regulatory Matters –Refer to Notes 1 and 2 to the financial statements

Critical Audit Matter Description

The Company is subject to rate regulation by the Public Utility Commission of Texas (the “PUCT”), which has jurisdiction with respect to the rates of electric transmission and distribution companies in Texas. Management has determined it meets the requirements under accounting principles generally accepted in the United States of America to prepare its financial statements applying the specialized rules to account for effects of cost-based rate regulation.

57

The economic effects of regulation can result in regulated companies recording costs that have been, or are deemed probable to be, allowed in the ratemaking process in a period different from the period in which the costs would be charged to expense by an unregulated enterprise. When this occurs, costs are deferred as regulatory assets and recorded as expenses in the periods when those same amounts are reflected in rates. Additionally, regulators can impose liabilities upon a regulated company for amounts previously collected from customers and for amounts that are expected to be refunded to customers (regulatory liabilities). The PUCT’s regulation of rates is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital. While the Company has indicated it expects to recover costs from customers through regulated rates, there is a risk that the PUCT will not approve: (1) full recovery of the costs of providing utility service or (2) full recovery of all amounts invested in the utility business and a reasonable return on that investment.

We identified the impact of rate regulation as a critical audit matter due to the significant judgments made by management in assessing whether the regulatory assets are probable of future recovery and the regulatory liabilities properly reflect all expected amounts of refund to customers by considering factors such as changes in the regulatory environment and recent rate orders. Auditing these judgments required specialized knowledge of accounting for rate regulation due to its inherent complexities.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to regulatory matters and accounting for the impacts of rate regulation included the following, among others:

We tested the effectiveness of management’s internal controls over the evaluation of the likelihood of (1) the recovery in future rates of costs deferred as regulatory assets, and (2) a refund or a future reduction in rates that should be reported as regulatory liabilities, including management’s controls over the initial recognition of amounts deferred as regulatory assets or liabilities and the monitoring and evaluation of regulatory developments that may affect reported balances.

We read relevant regulatory orders issued by the PUCT for the Company, applicable new legislation enacted in Texas, and other publicly available information to assess management’s judgments regarding the likelihood of recovery or refunds in future rates, including consideration of precedents of the PUCT’s treatment of similar costs under similar circumstances. We also evaluated this external information and compared to management’s recorded regulatory asset and liability balances for completeness.

For regulatory matters in process, we inspected the Company’s filings with the PUCT and the filings with the PUCT by intervenors and others that may impact regulatory assets and liabilities, for any evidence that might contradict management’s assertions.

We evaluated the Company’s disclosures related to the impacts of rate regulation, including the balances recorded and regulatory developments.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES

Description of Business

References in this report to “we,” “our,” “us” and “the company” are to Oncor and/or its subsidiaries as apparent in the context. See “Glossary” for the definition of terms and abbreviations.

We are a regulated electricity transmission and distribution company that provides the essential service of delivering electricity safely, reliably and economically to end-use consumers through our electrical systems, as well as providing transmission grid connections to merchant generation facilities and interconnections to other transmission grids in Texas. Our transmission and distribution rates are regulated by the PUCT and certain cities, and in certain limited instances, by the FERC. We are not a seller of electricity, nor do we purchase electricity for resale. We are a direct, majority-owned subsidiary of Oncor Holdings, which is indirectly and wholly owned by Sempra. Oncor Holdings owns 80.25% of our membership interests and Texas Transmission owns 19.75% of our membership interests. We are managed as an integrated business; consequently, there is only one reportable segment.

Ring-Fencing Measures

Since 2007, various ring-fencing measures have been taken to enhance our credit quality and the separateness between the Oncor Ring-Fenced Entities and entities with ownership interests in Oncor or Oncor Holdings. These ring-fencing measures serve to mitigate the Oncor Ring-Fenced Entities’ credit exposure to Sempra and its affiliates and any other direct or indirect owners of Oncor and Oncor Holdings, and to reduce the risk that the assets and liabilities of the Oncor Ring-Fenced Entities would be substantively consolidated with the assets and liabilities of any Sempra entity or any other direct or indirect owners of Oncor and Oncor Holdings in connection with a bankruptcy of any such entities. These measures include the November 2008 sale of 19.75% of Oncor’s equity interests to Texas Transmission.

In March 2018, Sempra indirectly acquired Oncor Holdings in the Sempra Acquisition. That transaction was approved by the PUCT in the Sempra Order, which order outlines certain ring-fencing measures, governance mechanisms and restrictions that apply to Oncor Holdings and Oncor after the Sempra Acquisition. As a result of these ring-fencing measures, Sempra does not control Oncor, and the ring-fencing measures limit Sempra’s ability to direct the management, policies and operations of Oncor, including the deployment or disposition of Oncor’s assets, declarations of dividends, strategic planning and other important corporate issues and actions. Our LLC Agreement requires PUCT approval of certain revisions to the agreement, including, among other things, revisions to our governance structure and other various ring-fencing measures.

None of the assets of the Oncor Ring-Fenced Entities are available to satisfy the debt or obligations of any Sempra entity or any other direct or indirect owner of Oncor or Oncor Holdings. The assets and liabilities of the Oncor Ring-Fenced Entities are separate and distinct from those of any Sempra entities and any other direct or indirect owner of Oncor or Oncor Holdings. We do not bear any liability for debt or contractual obligations of Sempra and its affiliates or any other direct or indirect owner of Oncor or Oncor Holdings, and vice versa. Accordingly, our operations are conducted, and our cash flows are managed, independently from Sempra and its affiliates and any other direct or indirect owner of Oncor or Oncor Holdings.

Oncor is a limited liability company governed by a board of directors, not its members. The Sempra Order and our LLC Agreement require that the board of directors of Oncor consist of thirteen members, constituted as follows:

seven Disinterested Directors, who (i) shall be independent directors in all material respects under the rules of the New York Stock Exchange in relation to Sempra or its subsidiaries and affiliated entities and any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, and (ii) shall have no material relationship with Sempra or its subsidiaries or affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, currently or within the previous ten years;

two members designated by Sempra (through Oncor Holdings);

two members designated by Texas Transmission; and

two current or former officers of Oncor (each, an Oncor Officer Director).

63

Until March 9, 2028, in order for a current or former officer of Oncor to be eligible to serve as an Oncor Officer Director, the officer cannot have worked for Sempra or any of its subsidiaries or affiliated entities (excluding Oncor Holdings and Oncor) or any other entity with a direct or indirect ownership interest in Oncor or Oncor Holdings in the ten-year period prior to the date on which the officer first became employed by Oncor. Oncor Holdings, at the direction of STIH, has the right to nominate and/or seek the removal of the Oncor Officer Directors, subject to approval by a majority of the Oncor board of directors.

In addition, the Sempra Order provides that Oncor’s board of directors cannot be overruled by the board of directors of Sempra or any of its subsidiaries on dividend policy, the issuance of dividends or other distributions (except for contractual tax payments), debt issuance, capital expenditures, operation and maintenance expenditures, management and service fees, and appointment or removal of members of the board of directors, provided that certain actions may also require the additional approval of the Oncor Holdings board of directors. The Sempra Order also provides that any changes to the size, composition, structure or rights of the board of directors must first be approved by the PUCT. In addition, if Sempra acquires Texas Transmission’s interest in Oncor, the two board of director positions on Oncor’s board of directors that Texas Transmission is entitled to appoint will be eliminated and the size of Oncor’s board of directors will be reduced by two.

Additional regulatory commitments, governance mechanisms and restrictions provided in the Sempra Order and our LLC Agreement to ring-fence Oncor from its owners include, among others:

A majority of the Disinterested Directors of Oncor and the directors designated by Texas Transmission that are present and voting (of which at least one must be present and voting) must approve any annual or multi-year budget if the aggregate amount of capital expenditures or operation and maintenance expenditures in such budget is more than a 10% increase or decrease from the corresponding amounts of such expenditures in the budget for the preceding fiscal year or multi-year period, as applicable;

Oncor may not pay any dividends or make any other distributions (except for contractual tax payments) if a majority of its Disinterested Directors or either of the two directors appointed by Texas Transmission determines that it is in the best interests of Oncor to retain such amounts to meet expected future requirements;

At all times, Oncor will remain in compliance with the debt-to-equity ratio established by the PUCT from time to time for ratemaking purposes, and Oncor will not pay dividends or other distributions (except for contractual tax payments) if such payment would cause its debt-to-equity ratio to exceed the debt-to-equity ratio approved by the PUCT;

If the credit rating on Oncor’s senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), Oncor will suspend dividends and other distributions (except for contractual tax payments), unless otherwise allowed by the PUCT;

Without the prior approval of the PUCT, neither Sempra nor any of its affiliates (excluding Oncor) will incur, guaranty or pledge assets in respect of any indebtedness that is dependent on the revenues of Oncor in more than a proportionate degree than the other revenues of Sempra or on the membership interests of Oncor, and there will be no debt at STH or STIH at any time following the closing of the Sempra Acquisition;

Neither Oncor nor Oncor Holdings will lend money to, borrow money from, or share credit facilities with, Sempra or any of its affiliates (other than Oncor subsidiaries), or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings; and

There must be maintained certain “separateness measures” that reinforce the legal and financial separation of Oncor from its owners, including a requirement that dealings between Oncor, Oncor Holdings and their subsidiaries with Sempra, any of Sempra’s other affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings, must be on an arm’s-length basis, limitations on affiliate transactions, separate recordkeeping requirements and a prohibition on Sempra or its affiliates or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings pledging Oncor assets or membership interests for any entity other than Oncor.

Basis of Presentation

Our consolidated financial statements have been prepared in accordance with GAAP governing rate-regulated operations. We also apply the guidance of ASC 810, Consolidations, to determine when an entity that is insufficiently capitalized or not controlled through its voting interests, referred to as a VIE, should be consolidated. All dollar amounts in the financial statements and tables in the notes are stated in U.S. dollars in millions unless otherwise indicated.

Use of Estimates

Preparation of our financial statements requires management to make estimates and assumptions about future events that affect the reporting of assets and liabilities at the balance sheet dates and the reported amounts of revenue and expense during the period. These estimates include, but are not limited to, the effects of regulation; recovery of long-lived assets; certain assumptions made in accounting for pension and OPEB; asset retirement obligations; income and other taxes; valuation of certain financial assets and liabilities; and accounting for contingencies. In the event estimates and/or assumptions prove to be different from actual amounts, adjustments are made in subsequent periods to reflect more current information.

Accounting for the Effects of Certain Types of Regulation

We are subject to rate regulation and our financial statements reflect regulatory assets and liabilities in accordance with accounting standards related to the effect of certain types of regulation. Regulatory assets and liabilities represent probable future revenues that will be recovered from or refunded to customers through the ratemaking process based on PURA and/or the PUCT’s orders, precedents or substantive rules. Rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital subject to PUCT review for reasonableness. Regulatory decisions can have an impact on the recovery of costs, the rate earned on invested capital and the timing and amount of assets to be recovered by rates. See Note 2 for more information regarding regulatory assets and liabilities.

Revenue Recognition

Oncor’s revenue is billed under tariffs approved by the PUCT and the majority of revenues are related to providing electric delivery service to consumers. Tariff rates are designed to recover the cost of providing electric delivery service including a reasonable rate of return on invested capital. Revenues are generally recognized when the underlying service has been provided in an amount prescribed by the related tariff. See Note 3 for additional information regarding revenues.

Interest Rate Derivatives, Hedge Accounting and Mark-to-Market Accounting

We are exposed to interest rates primarily as a result of our current and expected use of financing. We may, from time to time, utilize interest rate derivative instruments typically designated as cash flow hedges, to lock in interest rates in anticipation of future financings. We may designate an interest rate derivative instrument as a cash flow hedge if it effectively converts anticipated cash flows associated with interest payments to a fixed dollar amount. Designating interest rate derivative instruments as cash flow hedges is dependent on the business context in which the instrument is being used, the effectiveness of the instrument in offsetting the risk that the future cash flows of interest payments may vary, and other criteria. In accounting for cash flow hedges, derivative assets and liabilities are recorded on the balance sheet at fair value with an offset to other comprehensive income (loss). Amounts remain in AOCI and are reclassified into net income as the interest expense on the related debt affects net income.

The fair value of an interest rate derivative instrument is recognized on the balance sheet as a derivative asset or liability and changes in the fair value are recognized in net income if the criteria for cash flow hedge accounting are not met or if the instrument is not designated as a cash flow hedge. This recognition is referred to as “mark-to-market” accounting.

Impairment of Long-Lived Assets and Goodwill

We evaluate long-lived assets (including intangible assets with finite lives) for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable.

65

We also evaluate goodwill for impairment annually on October 1 and whenever events or changes in circumstances indicate that an impairment may exist. The determination of the existence of these and other indications of impairment involves judgments that are subjective in nature and may require the use of estimates in forecasting future results and cash flows.

For our annual goodwill impairment testing, we generally have the option to directly perform a quantitative assessment or first make a qualitative assessment of whether it is more likely than not that our estimated enterprise fair value is less than our enterprise carrying value before applying the quantitative assessment. If we elect to perform the qualitative assessment, we evaluate relevant events and circumstances, including but not limited to, macroeconomic conditions, industry and market considerations, cost factors and our overall financial performance. If, after assessing these qualitative factors, we determine that it is more-likely-than-not that our estimated enterprise fair value is less than our enterprise carrying book value, then we perform a quantitative assessment. If, after performing the quantitative assessment, we determine that goodwill is impaired, we record the amount of goodwill impairment as the excess of enterprise carrying book value over estimated enterprise fair value, not to exceed the carrying amount of goodwill.

For our annual goodwill impairment testing as of October 1, 2023, we elected to make a qualitative assessment of whether it is more likely than not that our enterprise fair value is less than our enterprise carrying value. We concluded that our estimated enterprise fair value was more likely than not greater than our enterprise carrying book value. As a result, no quantitative assessment for impairment was required and no impairment was recognized in 2023. For our annual goodwill impairment testing as of October 1, 2022, we elected to perform a quantitative assessment. We estimated our enterprise fair value by weighting results from a market-based approach and an income-based approach. Key assumptions in the valuation methodologies for goodwill included terminal value, discount rates, and comparable multiples from publicly traded companies in our industry. Based on our analysis, we determined that our estimated enterprise fair value was in excess of our enterprise carrying book value, indicating none of our goodwill was impaired and no impairment was recognized in 2022.

Goodwill totaling $4.740 billion was reported on our balance sheet at both December 31, 2023 and 2022.

Provision in Lieu of Income Taxes

Our tax sharing agreement with Oncor Holdings, Texas Transmission and STH provides for the calculation of amounts related to income taxes for each of Oncor Holdings and Oncor substantially as if these entities were taxed as corporations and requires payments to the members determined on that basis (without duplication for any income taxes paid by a subsidiary of Oncor Holdings).

We are a partnership for U.S. federal income tax purposes. Accordingly, while partnerships are not subject to income taxes, in consideration of the presentation of our financial statements as an entity subject to cost-based regulatory rate-setting processes, with such costs historically including income taxes, the financial statements present amounts determined under the tax sharing agreement as “provision in lieu of income taxes” and “liability in lieu of deferred income taxes”. Such amounts are determined in accordance with the provisions of the accounting guidance for income taxes and accounting standards that provide interpretive guidance for accounting for uncertain tax positions and thus differences between the book and tax bases of assets and liabilities are accounted for as if we were a stand-alone corporation. In the event such amounts are not paid under the tax sharing agreement, it is probable that this regulatory liability will continue to be included in Oncor’s rate setting processes.

We classify any interest and penalties expense related to uncertain tax positions as current provision in lieu of income taxes as discussed in Note 4.

Defined Benefit Pension Plans and OPEB Plans

We have liabilities under pension plans that offer benefits based on either a traditional defined benefit formula or a cash balance formula and OPEB Plans that offer certain health care and life insurance benefits to eligible employees and their eligible dependents upon the retirement of such employees. Costs of pension and OPEB Plans are dependent on numerous factors, assumptions and estimates. See Note 9 for additional information regarding pension and OPEB Plans.

66

System of Accounts

Our accounting records have been maintained in accordance with the FERC Uniform System of Accounts as adopted by the PUCT.

Property, Plant and Equipment

Property, plant and equipment is stated at original cost. The cost of self-constructed property additions includes materials and both direct and indirect labor and applicable overhead and AFUDC.

Depreciation of property, plant and equipment is calculated on a straight-line basis over the estimated service lives of the properties based on depreciation rates approved by the PUCT. As is common in the industry, depreciation expense is recorded using composite depreciation rates that reflect blended estimates of the lives of major asset groups as compared to depreciation expense calculated on a component asset-by-asset basis. Depreciation rates include plant removal costs as a component of depreciation expense, consistent with regulatory treatment. Actual removal costs incurred are charged to accumulated depreciation. Accrued removal costs in excess of incurred removal costs are reclassified as a regulatory liability to retire assets in the future.

Franchise Taxes

Franchise taxes are assessed to us by local governmental bodies, based on kWh delivered and are a principal component of taxes other than amounts related to income taxes as reported in the income statement. Franchise taxes are not a “pass through” item. The rates we charge customers are intended to recover the franchise taxes, but we are not acting as an agent to collect the taxes from customers.

Allowance for Funds Used During Construction

AFUDC is a regulatory cost accounting procedure whereby both interest charges on borrowed funds and a return on equity capital used to finance construction are included in the recorded cost of utility plant and equipment being constructed. AFUDC is capitalized on eligible projects involving construction periods lasting greater than thirty days. The interest portion of capitalized AFUDC is accounted for as a reduction to interest expense and the equity portion of capitalized AFUDC is accounted for as other income. See Note 11 for detail of amounts reducing interest expense and increasing other income.

Cash, Cash Equivalents and Restricted Cash

For purposes of reporting cash and cash equivalents, highly liquid investments with original maturities of three months or less at the date of purchase are considered to be cash equivalents.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported on the Consolidated Balance Sheets to the sum of such amounts reported on the Statements of Consolidated Cash Flows:

	At December 31,
	2023		2022
Cash, cash equivalents and restricted cash
Cash and cash equivalents	$	19	$	10
Restricted cash, current (a)		24		16
Restricted cash, noncurrent (a)		108		72
Total cash, cash equivalents and restricted cash on the statements of consolidated cash flows	$	151	$	98

____________

(a)Restricted cash represents amounts deposited with Oncor for customer advances for construction that are subject to probable return in accordance with PUCT rules, ERCOT requirements or our tariffs relating to generation interconnection and construction and/or extension of electric delivery system facilities. We maintain these amounts in separate escrow accounts.

67

Fair Value of Nonderivative Financial Instruments

The carrying amounts for financial assets classified as current assets and the carrying amounts for financial liabilities classified as current liabilities approximate fair value due to the short maturity of such instruments. The fair values of other financial instruments, for which carrying amounts and fair values have not been presented, are not materially different than their related carrying amounts. The following discussion of fair value accounting standards applies primarily to our determination of the fair value of assets in the pension plans’ and OPEB Plans’ trusts (see Note 9) and long-term debt (see Note 6).

Accounting standards related to the determination of fair value define fair value as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. We use a “mid-market” valuation convention (the mid-point price between bid and ask prices) as a practical expedient to measure fair value for the majority of our assets and liabilities subject to fair value measurement on a recurring basis. We primarily use the market approach for recurring fair value measurements and use valuation techniques to maximize the use of observable inputs and minimize the use of unobservable inputs.

We categorize our assets and liabilities recorded at fair value based upon the following fair value hierarchy:

Level 1 valuations use quoted prices in active markets for identical assets or liabilities that are accessible at the measurement date. An active market is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2 valuations use inputs that, in the absence of actively quoted market prices, are observable for the asset or liability, either directly or indirectly. Level 2 inputs include: (a) quoted prices for similar assets or liabilities in active markets, (b) quoted prices for identical or similar assets or liabilities in markets that are not active, (c) inputs other than quoted prices that are observable for the asset or liability such as interest rates and yield curves observable at commonly quoted intervals and (d) inputs that are derived principally from or corroborated by observable market data by correlation or other means. Our Level 2 valuations utilize over-the-counter broker quotes, quoted prices for similar assets or liabilities that are corroborated by correlations or other mathematical means and other valuation inputs.

Level 3 valuations use unobservable inputs for the asset or liability. Unobservable inputs are used to the extent observable inputs are not available, thereby allowing for situations in which there is little, if any, market activity for the asset or liability at the measurement date. We use the most meaningful information available from the market combined with internally developed valuation methodologies to develop our best estimate of fair value.

We utilize several different valuation techniques to measure the fair value of assets and liabilities, relying primarily on the market approach of using prices and other market information for identical and/or comparable assets and liabilities for those items that are measured on a recurring basis.

The fair value of certain investments is measured using the NAV per share as a practical expedient. Such investments measured at NAV are not required to be categorized within the fair value hierarchy.

Contingencies

Our financial results may be affected by judgments and estimates related to contingencies. For loss contingencies, we accrue the loss if an event has occurred on or before the balance sheet date, and:

information available through the date we file our financial statements indicates it is probable that a loss has been incurred, given the likelihood of uncertain future events; and

the amount of the loss can be reasonably estimated.

We do not accrue contingencies that might result in gains. We continuously assess contingencies for litigation claims, environmental remediation and other events. See Note 7 for a discussion of contingencies.

Accounting Standards Updates (ASU)

ASU 2023-07 Segment reporting (ASC 280)

In November 2023, the Financial Accounting Standards Board (FASB) issued ASU 2023-07, which expands reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. This ASU requires that a public entity disclose, on an annual and interim basis, significant segment expenses that are regularly provided to an entity's chief operating decision maker (CODM), a description of other segment items by reportable segment, and any additional measures of a segment's profit or loss used by the CODM when deciding how to allocate resources. A public entity that has a single reportable segment is also required to provide all the disclosures required by this ASU and all existing segment disclosures in ASC 280.

Annual disclosures are required for fiscal years beginning after December 15, 2023. Interim disclosures are required for periods within fiscal years beginning after December 15, 2024. Retrospective application is required for all prior periods presented, and early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures.

ASU 2023-09 Improvements to Income Tax Disclosures (ASC 740)

In December 2023, the FASB issued ASU 2023-09, which expands income tax disclosure requirements to include additional information related to the rate reconciliation of our effective tax rates to statutory rates, as well as additional disaggregation of taxes paid. This ASU also removed disclosures related to certain unrecognized tax benefits and deferred taxes. ASU 2023-09 is effective for fiscal years beginning after December 15, 2024. This ASU may be applied prospectively or retrospectively, and early adoption is permitted. We are currently assessing the impact of the requirements on our consolidated financial statements and disclosures.

All other newly issued accounting pronouncements not yet effective have been deemed either immaterial or not applicable.

2. REGULATORY MATTERS

Rate Proceedings

Base Rate Review (PUCT Docket No. 53601)

On April 6, 2023, the PUCT issued a final order in our comprehensive base rate review filed in May 2022 with the PUCT and the cities in our service territory that have retained original jurisdiction over rates. New base rates implementing the final order went into effect on May 1, 2023. Key findings made by the PUCT in the final order include setting our authorized return on equity at 9.7% (a decrease from our prior authorized return on equity of 9.8%), maintaining our regulatory capital structure at 57.5% debt to 42.5% equity, approving our requested regulatory asset amortization period of five years, changing depreciation rates and lives of certain depreciable assets, and approving our requested increase for our annual self-insurance reserve accrual primarily associated with storm related costs. In addition, the final order excluded from rates an acquisition premium and its associated amortization costs relating to certain plant facilities acquired by Oncor in 2019, as well as $65 million of certain employee benefit and compensation related costs that we had previously capitalized primarily to property, plant and equipment during the period of 2017 through 2021. As a result, we recognized a charge against income in the first quarter of 2023 for the effects of that $65 million disallowance, as well as an additional $4 million charge against income due to certain similar employee benefit and compensation related costs that were capitalized during 2022. The total $69 million ($54 million after-tax) write-off consisted of a $55 million ($43 million after-tax) write-off of disallowed capitalized property, plant and equipment reflected in operating expenses and a $14 million ($11 million after-tax) write-off of non-operating cost disallowances related to these disallowed employee benefit and compensation related costs.

On June 30, 2023, the PUCT issued an order on rehearing in response to the motions for rehearing filed by us and certain intervening parties in the proceeding. The order on rehearing made certain technical and typographical corrections to the final order, but otherwise affirmed the material provisions of the final order and did not require modification of the rates that went into effect on May 1, 2023. On September 22, 2023, we filed an appeal in Travis County District Court. The appeal sought judicial review of certain of the order on rehearing’s rate base disallowances (the disallowed 2019

69

acquisition premium and its associated amortization costs as well as certain of the disallowed employee benefit and compensation related costs that we had previously capitalized) and related expense effects of those disallowances. On February 22, 2024, the court dismissed the appeal for lack of jurisdiction. We are currently evaluating whether to appeal that ruling.

Capital Trackers

Interim DCRF and TCOS rate adjustments, also known as capital trackers, allow us to recover, subject to reconciliation, the cost of certain distribution and transmission investments, respectively, before the investments are considered for prudency in a base rate review. In June 2023, legislation was enacted by the Texas Legislature that increased the number of interim DCRF rate adjustment applications that may be filed by utilities in a single year for certain distribution-related investments from one application to up to two applications per year. Also, under PUCT rules, we can file up to two interim TCOS rate adjustment applications in a calendar year to reflect changes in our invested transmission capital. These interim rate applications are subject to a regulatory proceeding and PUCT approval. Investments included in these capital trackers are also subject to prudence review by the PUCT in the next base rate review following such adjustments, with a potential for the PUCT to also order refunds of previously collected amounts if a particular investment is found to be imprudent or inappropriately included in an interim rate adjustment.

TCOS revenues are also impacted by transmission billing units, which are updated to reflect certain changes in average ERCOT-wide peak electricity demand.

In 2023, Oncor filed the following interim rate update applications with the PUCT:

Filing Type	PUCT Docket No.	Investment Through	Filed	Effective Date	Annual Revenue Impact (a)
DCRF	55525	June 2023 (b)	September 2023	December 2023	$	53
TCOS	55282	June 2023 (c)	July 2023	September 2023	$	42
DCRF	55190	December 2022 (d)	June 2023	September 2023	$	153

____________

(a)Annual revenue impact represents the incremental annual revenue impact, after taking into account revenue effects of prior applicable rate adjustments.

(b)Reflects distribution capital investments generally put into service during the period from January 1, 2023 through June 30, 2023.

(c)Reflects transmission capital investments generally put into service during the period from January 1, 2022 through June 30, 2023.

(d)Reflects distribution capital investments generally put into service during the period from January 1, 2022 through December 31, 2022.

Regulatory Assets and Liabilities

We are subject to rate regulation and our financial statements reflect regulatory assets and liabilities in accordance with accounting standards related to the effect of certain types of regulation. Regulatory assets and liabilities represent probable future revenues that will be recovered from or refunded to customers through the ratemaking process based on PURA and/or the PUCT’s orders, precedents or substantive rules. Rate regulation is premised on the full recovery of prudently incurred costs and a reasonable rate of return on invested capital subject to PUCT review for reasonableness. Regulatory decisions can have an impact on the recovery of costs, the rate earned on invested capital and the timing and amount of assets to be recovered by rates.

On May 1, 2023, as part of the implementation of new base rates reflecting the final order in our comprehensive base rate review (PUCT Docket No. 53601), we commenced a five-year amortization period for certain regulatory assets and liabilities accrued through the end of the December 31, 2021 test year.

70

The following table presents components of our regulatory assets and liabilities and their remaining recovery periods in effect at December 31, 2023.

3. REVENUES

General

Our revenue is billed monthly under tariffs approved by the PUCT and the majority of revenues are related to providing electric delivery service to consumers. Tariff rates are designed to recover the cost of providing electric delivery service to customers including a reasonable rate of return on invested capital. As the volumes delivered can be directly measured, our revenues are recognized when the underlying service has been provided in an amount prescribed by the related tariff. We recognize revenue in the amount that we have the right to invoice. Substantially all of our revenues are from contracts with customers except for alternative revenue program revenues discussed below.

Reconcilable Tariffs

The PUCT has designated certain tariffs (primarily TCRF, EECRF, rate case expense riders and mobile generation riders) as reconcilable, which means the differences between amounts billed under these tariffs and the related incurred costs are deferred as either regulatory assets or regulatory liabilities. Accordingly, at prescribed intervals, future tariffs are adjusted to either collect regulatory assets or refund regulatory liabilities.

Alternative Revenue Program

The PUCT has implemented an incentive program allowing us to earn energy efficiency program performance bonuses by exceeding PURA-mandated energy efficiency program targets. This incentive program and the related performance bonus revenues are considered an “alternative revenue program” under GAAP. Annual performance bonuses are recognized as revenue when approved by the PUCT, typically in the third or fourth quarter each year. The PUCT approved annual energy efficiency program performance bonuses of $21 million and $28 million in 2023 and 2022, respectively, that we recognized in other miscellaneous revenues.

Disaggregation of Revenues

The following table reflects electric delivery revenues disaggregated by tariff:

	Years Ended December 31,
	2023		2022		2021
Operating revenues
Revenues contributing to earnings:
Distribution base revenues	$	2,628	$	2,447	$	2,217

Total operating revenues	$	5,586	$	5,243	$	4,764

72

Customers

At December 31, 2023, our distribution business customers primarily consisted of over 100 REPs that sell electricity we distribute to end-use consumers in our certificated service area. The majority of consumers of the electricity we deliver through our distribution business are free to choose their electricity supplier from REPs who compete for their business. Our network transmission revenues are collected from load serving entities benefitting from our transmission system. Our transmission business customers consist of municipally-owned utilities, electric cooperatives and other distribution companies. Revenues from REP subsidiaries of our two largest customers, collectively represented 25% and 23%, respectively, of our total operating revenues for the year ended December 31, 2023, 26% and 24%, respectively, of our total operating revenues for the year ended December 31, 2022 and 25% and 23%, respectively, of our total operating revenues for the year ended December 31, 2021. No other customer represented more than 10% of our total operating revenues during such periods.

Variability

Our revenues and cash flows are subject to seasonality, timing of customer billings, weather conditions and other electricity usage drivers, with revenues being highest in the summer. Payment of customer billings is due 35 days after invoicing. Under a PUCT rule relating to the Certification of Retail Electric Providers, write-offs of uncollectible amounts owed by REPs are recoverable as a regulatory asset.

Pass-through Expenses

Revenue equal to expenses that are allowed to be passed-through to customers (primarily third-party wholesale transmission service and energy efficiency program costs) are recognized at the time the expense is recognized. Franchise taxes are assessed by local governmental bodies, based on kWh delivered and are not a “pass-through” item. The rates we charge customers are intended to recover the franchise taxes, but we are not acting as an agent to collect the taxes from customers; therefore, franchise taxes are reported as a principal component of “taxes other than amounts related to income taxes” instead of a reduction to “revenues” in the income statement.

The net amounts of $2.320 billion and $2.182 billion reported in the balance sheets at December 31, 2023 and 2022, respectively, as liability in lieu of deferred income taxes include amounts previously recorded as net deferred tax liabilities. In connection with the sale of equity interests to Texas Transmission in 2008, we became a partnership for U.S. federal income tax purposes, and the temporary differences that gave rise to the deferred taxes will, over time, become taxable to the equity holders. Under a tax sharing agreement among us and our equity holders (see Note 1), we make payments to the equity holders related to income taxes when amounts would have become due to the I.R.S. if Oncor was taxed as a corporation. Accordingly, as the temporary differences become taxable, we will pay the equity holders. In the event such amounts are not paid under the tax sharing agreement, it is probable that this regulatory liability will continue to be included in Oncor’s rate setting processes.

Accounting For Uncertainty in Provision in Lieu of Income Taxes

For federal income tax purposes, the statute of limitations is open for partnership tax returns for the years beginning after December 31, 2019. We filed refund claims for the tax years ending December 31, 2018 and 2019, but no additional

74

tax may be assessed for these tax years. We have also filed refund claims for the tax years ending December 31, 2020 and 2021. 

Texas margin tax returns are still open for tax years beginning after 2018. We have filed refund claims for the tax year ending December 31, 2018 (2019 report year), but no additional tax may be assessed for 2018.

We are not a member of another entity’s consolidated tax group and assess our liability for uncertain tax positions in our partnership returns. The following table represents the changes to the uncertain tax positions reported in other noncurrent liabilities in our consolidated balance sheets for the years ended December 31, 2023 and 2022:

	Years Ended December 31,
	2023		2022
Balance at January 1, excluding interest and penalties	$	1	$	-
Additions based on tax positions related to prior years		2		1
Balance at December 31, excluding interest and penalties	$	3	$	1

Noncurrent liabilities included $1 million of accrued interest related to uncertain tax positions at December 31, 2023 and negligible amounts at December 31, 2022 and 2021, respectively. There was $1 million recorded related to interest and penalties in the year ended December 31, 2023 and negligible amounts in the years ended December 31, 2022 and 2021, respectively. The federal income tax benefit on the interest accrued on uncertain tax positions, if any, is recorded as liability in lieu of deferred income taxes.

5. SHORT-TERM BORROWINGS

The following table reflects our outstanding short-term borrowings and available unused credit under the $2B Credit Facility and CP Program at December 31, 2023 and 2022:

	At December 31,
	2023		2022
Total $2B Credit Facility borrowing capacity	$	2,000	$	2,000
$2B Credit Facility outstanding borrowings		-		-
Commercial paper outstanding (a)		(282)		(198)
Letters of credit outstanding		-		-
Available unused credit	$	1,718	$	1,802

____________

(a)The weighted average interest rate for CP Notes was 5.54% and 4.58% at December 31, 2023 and December 31, 2022, respectively. All outstanding CP Notes at December 31, 2023 and December 31, 2022 had maturity dates of less than one year.

$2B Credit Facility

Our unsecured revolving $2B Credit Facility has a borrowing capacity of $2.0 billion and a maturity date of November 9, 2028. We have the option to request an increase in our borrowing capacity of up to $400 million in $100 million minimum increments, subject to certain conditions, including lender approvals. Borrowings under the $2B Credit Facility, if any, are classified as short-term on the balance sheet.

Borrowings under the $2B Credit Facility bear interest at a per annum rate equal to, at our option, (i) term SOFR for the interest period relevant to such borrowing, plus an adjustment of 0.10% (the SOFR Adjustment), plus an applicable margin of between 0.875% and 1.50%, depending on certain credit ratings assigned to us, or (ii) an alternate base rate (equal to the greatest of (1) the prime rate as quoted by The Wall Street Journal on such date, (2) the greater of the federal funds effective rate or the overnight bank funding rate, plus 0.50%, and (3) term SOFR for a one-month interest period on such date, plus the SOFR Adjustment, plus 1.0%), plus, in the case of clauses (1) through (3), an applicable margin of between 0.00% and 0.50%, depending on certain credit ratings assigned to our debt. The $2B Credit Facility also provides for an alternative rate of interest upon the occurrence of certain events related to the current rate of interest benchmark.

75

A commitment fee is payable quarterly in arrears and upon termination or commitment reduction at a rate per annum equal to between 0.075% and 0.225%, depending on certain credit ratings assigned to us, of the commitments under the $2B Credit Facility. Letter of credit fees under the $2B Credit Facility are payable quarterly in arrears and upon termination at a rate per annum equal to the applicable margin for adjusted term SOFR under the $2B Credit Facility. Fronting fees in an amount as separately agreed by Oncor and any fronting bank that issues a letter of credit are also payable quarterly in arrears and upon termination to each such fronting bank.

The $2B Credit Facility includes sustainability-linked pricing metrics related to specific environmental and employee health and safety sustainability objectives. The $2B Credit Facility provides that the applicable margin and commitment fee may be increased, decreased or have no change depending on our annual performance on the two sustainability-linked pricing metrics set forth in the facility. The maximum pricing adjustment in any given year is +/- 0.01% on the commitment fee and +/- 0.05% on the applicable margin.

The $2B Credit Facility requires that we maintain a maximum consolidated senior debt to consolidated total capitalization ratio of 0.65 to 1.00 and observe certain customary reporting requirements and other affirmative covenants. At December 31, 2023, we were in compliance with these covenants.

The $2B Credit Facility also contains customary events of default for facilities of this type, the occurrence of which would allow the lenders to accelerate all outstanding loans and terminate their commitments, including certain changes in control of Oncor that are not permitted transactions under the $2B Credit Facility and cross-default provisions in the event Oncor or any of its subsidiaries defaults on indebtedness in a principal amount in excess of $100 million or receives judgments for the payment of money in excess of $100 million that are not discharged or stayed within 60 days.

CP Program

We maintain the CP Program under which we may issue unsecured CP Notes (with a maturity date not exceeding 397 days from the date of issuance) on a private placement basis up to a maximum aggregate face or principal amount outstanding at any time of $2.0 billion. The proceeds of CP Notes issued under the CP Program are used for working capital and general corporate purposes. The CP Program obtains liquidity support from the $2B Credit Facility discussed above. We may utilize either the CP Program or the $2B Credit Facility, at our option, to meet our funding needs.

Deed of Trust

Our long-term senior secured notes are secured equally and ratably by a first priority lien on all property acquired or constructed by us for use in our electricity transmission and distribution business, subject to certain exceptions. The property is mortgaged under the Deed of Trust. The Deed of Trust permits us to secure indebtedness with the lien of the Deed of Trust up to the aggregate of (i) the amount of available bond credits, and (ii) 85% of the lower of the fair value or cost of certain property additions that could be certified to the Deed of Trust collateral agent.

Long-Term Debt-Related Activities in 2023

Senior Secured Notes

March 2023 Note Purchase Agreement

On March 29, 2023, we entered into a note purchase agreement (March 2023 NPA) with the purchasers named therein, which provided for the issuance by us of certain senior secured notes. Pursuant to the March 2023 NPA, on March 29, 2023, we sold $200 million aggregate principal amount of 5.50% Senior Secured Notes, Series C, due May 1, 2026 (Series C Notes), $72 million aggregate principal amount of 5.34% Senior Secured Notes, Series D, due May 1, 2031 (Initial Series D Notes) and $80 million aggregate principal amount of 5.45% Senior Secured Notes, Series E, due May 1, 2036 (Initial Series E Notes), and on April 26, 2023, we sold an additional $28 million aggregate principal amount of 5.34% Senior Secured Notes, Series D, due May 1, 2031 (Additional Series D Notes and, together with the Initial Series D Notes, the Series D Notes) and an additional $20 million aggregate principal amount of 5.45% Senior Secured Notes, Series E, due May 1, 2036 (Additional Series E Notes and together with the Initial Series E Notes, Series E Notes). The senior secured notes issued under the March 2023 NPA are secured pursuant to the Deed of Trust.

The March 2023 NPA provides for optional prepayment and make-whole payments with respect to any series of notes issued under the March 2023 NPA. The March 2023 NPA also contains customary covenants, restricting us, subject to certain exceptions, from among other things, entering into mergers and consolidations, and sales of substantial assets. In addition, the March 2023 NPA requires that we maintain a consolidated senior debt to consolidated total capitalization ratio of no greater than 0.65 to 1.00 and observe certain customary reporting requirements and other affirmative covenants.

The March 2023 NPA contains customary events of default, including the failure to pay principal or interest when due, among others. If any such event of default occurs and is continuing, among other remedies provided in the March 2023 NPA, the outstanding principal of the notes issued under the March 2023 NPA may be declared due and payable.

We used the proceeds from the sale of the senior secured notes under the March 2023 NPA for general corporate purposes, including repayment of outstanding CP Notes.

The Series C Notes bear interest at a rate of 5.50% per annum and mature on May 1, 2026. The Series D Notes bear interest at a rate of 5.34% per annum and mature on May 1, 2031. The Series E Notes bear interest at a rate of 5.45% per annum and mature on May 1, 2036. Interest on the senior secured notes issued on March 29, 2023 was accrued beginning from March 29, 2023. Interest on the senior secured notes issued on April 26, 2023 was accrued beginning from April 26, 2023. All interest will be payable semi-annually on May 1 and November 1 of each year, beginning on November 1, 2023.

Issuance of Senior Secured Notes Under Indenture (2028 Notes and 2052 Notes)

On May 11, 2023, we issued $600 million aggregate principal amount of 4.30% Senior Secured Notes due May 15, 2028 (2028 Notes) and $400 million aggregate principal amount of 4.95% Senior Secured Notes due September 15, 2052 (2052 Notes). The 2052 Notes constitute an additional issuance of our 4.95% Senior Secured Notes due 2052, $500 million of which we previously issued on September 8, 2022. The 2028 Notes and 2052 Notes were issued under one of our existing indentures and are secured pursuant to the Deed of Trust.

We used the proceeds (net of the initial purchasers’ discount fees, expenses and accrued interest) of approximately $970 million from the sale of the 2028 Notes and 2052 Notes for general corporate purposes, including to repay on May 11, 2023, the full amount of $625 million outstanding under our unsecured term loan credit agreement, dated January 24,

78

2023, the full amount of $150 million outstanding under our unsecured term loan credit agreement, dated March 22, 2023, and the then-full amount of $100 million outstanding under our AR Facility.

The 2028 Notes bear interest at a rate of 4.30% per annum and mature on May 15, 2028. The 2052 Notes bear interest at a rate of 4.95% per annum and mature on September 15, 2052. Interest on the 2028 Notes accrued from May 11, 2023 and will be payable semi-annually on May 15 and November 15 of each year, beginning on November 15, 2023. Interest on the 2052 Notes accrued from March 15, 2023, and will be payable semi-annually on March 15 and September 15 of each year, beginning on September 15, 2023. Prior to April 15, 2028 in the case of the 2028 Notes and March 15, 2052 in the case of the 2052 Notes, we may redeem such notes at any time, in whole or in part, at a price equal to 100% of their principal amount, plus accrued and unpaid interest and a “make-whole” premium. On and after April 15, 2028 in the case of the 2028 Notes and March 15, 2052 in the case of the 2052 Notes, we may redeem them at any time, in whole or in part, at a redemption price equal to 100% of the principal amount of such notes, plus accrued and unpaid interest.

Issuance of Senior Secured Notes Under Indenture (2033 Notes)

On November 13, 2023, we issued $800 million aggregate principal amount of 5.65% Senior Secured Notes due November 15, 2033 (2033 Notes). The 2033 Notes were issued under one of our existing indentures and are secured pursuant to the Deed of Trust.

We used the proceeds (net of the initial purchasers’ discount fees and expenses) of approximately $791 million from the sale of the 2033 Notes for general corporate purposes, including to repay the then-full amount of $500 million outstanding under our AR Facility.

The 2033 Notes bear interest at a rate of 5.65% per annum and mature on November 15, 2033. Interest on the 2033 Notes accrued from November 13, 2023 and will be payable semi-annually on May 15 and November 15 of each year, beginning on May 15, 2024. Prior to August 15, 2033, we may redeem such notes at any time, in whole or in part, at a price equal to 100% of their principal amount, plus accrued and unpaid interest and a “make-whole” premium. On and after August 15, 2033, we may redeem them at any time, in whole or in part, at a redemption price equal to 100% of the principal amount of such notes, plus accrued and unpaid interest.

AR Facility

On April 28, 2023, we and our bankruptcy-remote special purpose entity Receivables LLC, a wholly-owned subsidiary of Oncor, established the AR Facility, a revolving accounts receivable securitization facility. Under the terms of the AR Facility, Oncor sells or contributes all of its existing and future accounts receivable from REPs and certain related rights to Receivables LLC as contemplated by the terms of the AR Facility. Receivables LLC then pledges those REP receivables and related rights to the lenders under the AR Facility as collateral for borrowings. Oncor serves as servicer of the AR Facility and receives a fee from Receivables LLC equal to 1.00% per annum of the aggregate unpaid balance of receivables as of the last day of each settlement period.

Receivables LLC’s sole business consists of the purchase or acceptance through capital contributions of the receivables and related rights from Oncor and the subsequent retransfer of or granting of a security interest in such receivables and related rights to the administrative agent for the benefit of the lenders pursuant to the receivables financing agreement. Receivables LLC is a separate legal entity with its own separate creditors who will be entitled, upon its liquidation, to have amounts owed to them be satisfied out of Receivables LLC’s assets prior to any assets or value in Receivables LLC becoming available to Receivables LLC’s equity holder. The assets of Receivables LLC are not available to pay creditors of Oncor or any affiliate thereof.

Receivables LLC is considered a VIE. See Note 11 for more information related to our consolidated VIE.

Oncor has access to the AR Facility, under which Receivables LLC may borrow at any one time an amount equal to the borrowing base. The borrowing base is defined under the receivables financing agreement as an amount equal to the lesser of (i) the facility limit of $500 million and (ii) the amount calculated based on the outstanding balance of eligible receivables held as collateral at a particular time, subject to certain reserves, concentration limits, and other limitations.

79

At December 31, 2023, the borrowing base for the AR Facility was $500 million and no borrowings were outstanding under the AR Facility.

The agreements relating to the AR Facility contain customary representations and warranties, affirmative and negative covenants, and events of default, including but not limited to those providing for the acceleration of amounts owed under the AR Facility if, among other things, Receivables LLC fails to pay interest or other amounts due, Receivables LLC becomes insolvent or subject to bankruptcy proceedings or certain judicial judgments or breaches of certain representations and warranties and covenants. The AR Facility will terminate at the earlier of (i) April 28, 2026, (ii) the date on which the termination date is declared or deemed to have occurred upon the exercise of remedies by the administrative agent, or (iii) the date that is 30 days after notice by Receivables LLC. Subject to the consent of the administrative agent and the lenders, Receivables LLC may, 30 days prior to each anniversary date of the receivables financing agreement, extend the AR Facility in one-year increments subject to lender approvals.

Term Loan Credit Agreement Activity

On January 9, 2023, we repaid the remaining $100 million principal amount outstanding under a term loan credit agreement, dated July 6, 2022, that was due to mature on August 30, 2023. Following such repayment, no borrowings remained outstanding and the term loan credit agreement ceased to be in effect.

 On January 24, 2023, we entered into an unsecured term loan credit agreement with a commitment equal to an aggregate principal amount of $625 million. The term loan credit agreement had a maturity date of February 28, 2024. On January 27, 2023, we borrowed $500 million and on February 27, 2023, we borrowed the remaining $125 million under the term loan credit agreement. The proceeds from the borrowings were used for general corporate purposes, including repayment of outstanding CP Notes. Loans under the term loan credit agreement bore interest at a rate per annum equal to SOFR calculated based on term SOFR for a one-month interest period as of a specified date, plus the SOFR Adjustment, plus a spread of 0.85%. On May 11, 2023, we repaid the full $625 million aggregate principal amount outstanding under the term loan credit agreement. As a result of the repayment, no borrowings remained outstanding and the term loan credit agreement ceased to be in effect.

On March 22, 2023, we entered into an unsecured term loan credit agreement with a commitment equal to an aggregate principal amount of $150 million. The term loan credit agreement had a maturity date of April 30, 2024. On March 23, 2023, we borrowed $150 million under the term loan credit agreement. The proceeds from the borrowing were used for general corporate purposes, including repayment of outstanding CP Notes. Loans under the term loan credit agreement bore interest at a rate per annum equal to SOFR calculated based on term SOFR for a one-month interest period as of a specified date plus a spread of 0.95%. On May 11, 2023, we repaid the full $150 million aggregate principal amount outstanding under the term loan credit agreement. As a result of the repayment, no borrowings remained outstanding and the term loan credit agreement ceased to be in effect.

Interest Rate Hedge Transactions

In November 2023, we entered into interest rate hedge transactions hedging the variability of benchmark bond rates used to determine the interest rates on the anticipated issuance of ten-year senior secured notes. The hedges were terminated in November 2023 upon the issuance of our 2033 Notes, and a $4 million ($3 million after-tax) loss was reported in other comprehensive income. We expect approximately $3 million of the amount reported in accumulated other comprehensive loss at December 31, 2023 related to interest rate hedges entered into in November 2023, as well as interest rate hedges entered into in prior years to be reclassified into net income as an increase to interest expense within the next 12 months.

Long-Term Debt-Related Activities in 2024

Subsequent Borrowings under AR Facility

On January 30, 2024, we borrowed $300 million aggregate principal amount under the AR Facility.

$500M Credit Facility

On February 21, 2024, we entered into our new unsecured revolving $500M Credit Facility. The $500M Credit Facility has a borrowing capacity of $500 million and a maturity date of February 21, 2027. The $500M Credit Facility gives us the option to request an increase in our borrowing capacity of up to $500 million in $100 million minimum increments, subject to certain conditions, including lender approvals. The $500M Credit Facility also provides us with the option to request that each lender extend the term of its commitment for up to two additional one-year periods, subject to certain conditions, including lender approvals.

Borrowings under the $500M Credit Facility bear interest at a per annum rate equal to, at our option, (i) term SOFR for the interest period relevant to such borrowing, plus an adjustment of 0.10% (the SOFR Adjustment), plus an applicable margin of between 0.875% and 1.50%, depending on certain credit ratings assigned to us, or (ii) an alternate base rate (equal to the greatest of (1) the prime rate publicly announced from time to time by the administrative agent as its prime rate, (2) the federal funds effective rate, plus 0.50%, and (3) term SOFR for a one-month interest period on such date, plus the SOFR Adjustment, plus 1.0%), plus, in the case of clauses (1) through (3), an applicable margin of between 0.00% and 0.50%, depending on certain credit ratings assigned to our debt. The $500M Credit Facility also provides for an alternative rate of interest upon the occurrence of certain events related to the current rate of interest benchmark.

A commitment fee is payable quarterly in arrears and upon termination or commitment reduction at a rate per annum equal to between 0.075% and 0.625% of the commitments under the $500M Credit Facility, depending on certain credit ratings assigned to us and the utilization percentage. The utilization percentage is determined by dividing the aggregate principal amount of loans outstanding under the $500M Credit Facility by the total commitments.

On February 23, 2024, we submitted an irrevocable borrowing request under the $500M Credit Facility for a $220 million borrowing to be made on February 28, 2024. We intend to use the proceeds from the borrowing for general corporate purposes, including to repay outstanding CP Notes. Following the borrowing, $280 million will be available for future borrowings under the $500M Credit Facility.

7.COMMITMENTS AND CONTINGENCIES

Leases

General

A lease exists when a contract conveys the right to control the use of an identified asset for a period of time in exchange for consideration. As lessee, our leased assets primarily consist of our vehicle fleet and real estate leased for company offices and service centers. Our leases are accounted for as operating leases for GAAP purposes. At December 31, 2023 and 2022, we had $4 million and $5 million, respectively, in GAAP operating leases for temporary emergency electric energy facilities that are treated as capital leases solely for rate-making purposes as required by PURA. We generally recognize operating lease costs on a straight-line basis over the lease term in operating expenses. We are not a lessor to any material lease contracts.

As of the lease commencement date, we recognize a lease liability for our obligation to make lease payments, which we initially measure at present value using our incremental borrowing rate at the date of lease commencement, unless the rate implicit in the lease is readily determinable. We determine our incremental borrowing rate based on the rate of interest that we would have to pay to borrow an amount equal to the lease payments on a collateralized basis over a similar term in a similar economic environment. We also record a ROU asset for our right to use the underlying asset, which is initially equal to the lease liability and adjusted for any lease payments made at or before lease commencement, lease incentives and any initial direct costs.

Some of our lease agreements contain nonlease components, which represent items or activities that transfer a good or service. We separate lease components from nonlease components, if any, for our fleet vehicle and real estate leases for purposes of calculating the related lease liability and ROU asset.

Certain of our leases include options to extend the lease terms for up to 20 years, while others include options to terminate early. Our lease liabilities and ROU assets are based on lease terms that may include such options to extend or terminate the lease when it is reasonably certain that we will exercise that option.

Short-term Leases

Some of our contracts are short-term leases, which have a lease term of 12 months or less at lease commencement. As allowed by GAAP, we do not recognize a lease liability or ROU asset arising from short-term leases for all existing classes of underlying assets. We recognize short-term lease costs on a straight-line basis over the lease term.

Sales and Use Tax Audits

We are subject to sales and use tax audits in the normal course of business. As of December 31, 2023, the Texas State Comptroller’s office was conducting three sales and use tax audits for audit periods covering January 2010 through June 2013, July 2013 through December 2017, and January 2018 through December 2022.

In January 2024, we reached a settlement agreement with the Texas State Comptroller’s office for the sales and use tax audit for the January 2010 through June 2013 audit period that results in a total refund of $63 million, net of consulting fees. The effects of the net refund will be recorded in the first quarter of 2024. No other audit reports have been issued. While the outcome of the ongoing audits is uncertain, based on our analysis, we do not expect the ultimate resolution of these audits will have a material adverse effect on our financial position, results of operations, or cash flows.

83

Energy Efficiency Spending

We are required to annually invest in programs designed to improve customer electricity demand and consumption efficiencies to satisfy ongoing regulatory requirements. The requirement for the year 2024 is $49 million, which is recoverable through EECRF rates.

Legal/Regulatory Proceedings

On April 6, 2023, the PUCT issued a final order in our comprehensive base rate review filed in May 2022 with the PUCT and the cities in our service territory that have retained original jurisdiction over rates. New base rates implementing the final order went into effect on May 1, 2023. See Note 2 above for additional information regarding these proceedings. We are also involved in other legal and administrative proceedings in the normal course of business, the ultimate resolution of which, in the opinion of management, should not have a material effect upon our financial position, results of operations, or cash flows.

Labor Contracts

At December 31, 2023, approximately 17% of our full-time employees were represented by a labor union and covered by a collective bargaining agreement that expires in October 2026.

Environmental Contingencies

We must comply with environmental laws and regulations applicable to the handling and disposal of hazardous waste. We are in compliance with all current laws and regulations. The impact, if any, of changes to existing regulations or the implementation of new regulations is not determinable. The costs to comply with environmental regulations can be significantly affected by the following external events or conditions:

changes to existing state or federal regulation by governmental authorities having jurisdiction over control of toxic substances and hazardous and solid wastes, and other environmental matters, and

the identification of additional sites requiring clean-up or the filing of other complaints in which we may be asserted to be a potential responsible party.

We have not identified any significant potential environmental liabilities at this time.

8. MEMBERSHIP INTERESTS

Contributions

On February 16, 2024, we received cash capital contributions from our members totaling $240 million. During 2023, we received the following cash capital contributions from our members.

Receipt Dates	Amounts
February 13, 2023	$	106
April 27, 2023	$	115
July 27, 2023	$	115
October 26, 2023	$	116

Distributions

The Sempra Order and our LLC Agreement set forth various restrictions on distributions to our members. Among those restrictions is the commitment that we will make no distributions (other than contractual tax payments) to our members that would cause us to exceed our debt-to-equity ratio authorized by the PUCT. The distribution restrictions also include the ability of a majority of our Disinterested Directors, or either of the two member directors designated by Texas Transmission, to limit distributions to the extent each determines it is necessary to meet expected future requirements of Oncor (including continuing compliance with the PUCT debt-to-equity ratio commitment). In addition, the distribution restrictions also require us to suspend dividends and other distributions (except for contractual tax payments) if the credit

84

rating on our senior secured debt by any of the three major rating agencies falls below BBB (or the equivalent), unless otherwise allowed by the PUCT.

Our current authorized regulatory capital structure is 57.5% debt to 42.5% equity. The PUCT has the authority to determine what types of debt and equity are included in a utility’s regulatory debt-to-equity ratio. For purposes of this ratio, debt is calculated as long-term debt including any finance leases plus unamortized gains on reacquired debt less unamortized issuance expenses, premiums and losses on reacquired debt. Equity is calculated as membership interests determined in accordance with GAAP, excluding accumulated other comprehensive loss and the effects of acquisition accounting from a 2007 transaction. At December 31, 2023, our regulatory capitalization was 55.8% debt to 44.2% equity and as a result we had $714 million available to distribute to our members.

On February 14, 2024, our board of directors declared a cash distribution of $125 million, which was paid to our members on February 15, 2024. During 2023, our board of directors declared, and we paid, the following cash distributions to our members:

Declaration Dates	Payment Dates		Amounts
February 14, 2023	February 15, 2023	$	106
April 25, 2023	April 26, 2023	$	149

9. EMPLOYEE BENEFIT PLANS

Regulatory Recovery of Pension and OPEB Costs

PURA provides for our recovery of certain pension and OPEB costs related to the regulated utility service of our employees (and their eligible dependents) and the regulated utility service of certain employees (and their eligible dependents) of our former affiliated companies for periods prior to the deregulation and disaggregation of the Texas

85

electric market in 2002 (recoverable service). Accordingly, in 2005, we entered into an agreement with a former affiliate of us whereby we assumed responsibility for applicable pension and OPEB costs related to those personnel’s recoverable service. We subsequently entered into an agreement with a Vistra affiliate regarding provision of these benefits. Pursuant to that agreement, we currently sponsor an OPEB plan that provides certain retirement healthcare and life insurance benefits to eligible former employees of Oncor and Vistra (or their predecessors or affiliates) for whom both Oncor and Vistra bear a portion of the benefit responsibility. See “OPEB Plans” below for more information.

We are authorized to establish a regulatory asset or liability for the difference between the amounts of pension and OPEB costs approved in current billing rates and the actual amounts that would otherwise have been recorded as charges or credits to earnings related to recoverable service. Amounts deferred are ultimately subject to regulatory approval. At December 31, 2023 and 2022, we had recorded net regulatory assets totaling $291 million and $346 million, respectively, related to pension and OPEB costs, including amounts related to deferred expenses as well as amounts related to unfunded liabilities that otherwise would be recorded as other comprehensive income.

We have also assumed primary responsibility for pension benefits of a closed group of retired and terminated vested plan participants not related to our regulated utility business (non-recoverable service) in a 2012 transaction. Any retirement costs associated with non-recoverable service are not recoverable through rates.

Pension Plans

We sponsor the Oncor Retirement Plan and also have liabilities related to the Vistra Retirement Plan, both of which are qualified pension plans under Section 401(a) of the Code, and are subject to the provisions of ERISA. Employees do not contribute to either plan. These pension plans provide benefits to participants under one of two formulas: (i) a Cash Balance Formula under which participants earn monthly contribution credits based on their compensation and a combination of their age and years of service, plus monthly interest credits or (ii) a Traditional Retirement Plan Formula based on years of service and the average earnings of the three years of highest earnings. The interest component of the Cash Balance Formula is variable and is determined using the yield on 30-year Treasury bonds. The weighted-average interest crediting rate assumption for the Cash Balance Formula was 3.0% for 2023. Under the Cash Balance Formula, future increases in earnings will not apply to prior service costs.

All eligible employees hired after January 1, 2001 participate under the Cash Balance Formula. Certain employees, who, prior to January 1, 2002, participated under the Traditional Retirement Plan Formula, continue their participation under that formula. It is Oncor’s policy to fund its plans on a current basis to the extent required under existing federal tax and ERISA regulations.

We also maintain the Supplemental Retirement Plan for certain employees whose retirement benefits cannot be fully earned under the qualified retirement plan. Supplemental Retirement Plan amounts are included in the reported pension amounts below.

At December 31, 2023, the pension plans’ projected benefit obligation included a net actuarial loss of $63 million attributable primarily to a decrease in discount rates due to changes in the corporate bond markets, actuarial assumption updates to reflect recent demographic experience and 2023 market conditions, and plan experience different than expected.

OPEB Plans

We currently sponsor two OPEB Plans. One plan covers our eligible current and future retirees whose services are 100% attributed to the regulated business. Effective January 1, 2018, we established a second plan to cover eligible retirees of Oncor and Vistra (or their predecessors or affiliates) whose employment services were assigned to both Oncor (or a predecessor regulated utility business) and the non-regulated business of Vistra. Vistra is solely responsible for its portion of the liability for retiree benefits related to those retirees.

Oncor’s contribution policy for the OPEB Plans is to place in irrevocable external trusts dedicated to the payment of OPEB expenses an amount at least equal to the OPEB expense recovered in rates.

At December 31, 2023, the OPEB Plans’ projected benefit obligation included a net actuarial gain of $2 million attributable primarily to updates to health care assumptions and plan experience different than expected, partially offset by losses attributable to decreasing discount rates due to changes in the corporate bond markets.

86

Pension and OPEB Costs Recognized as Expense

Pension and OPEB amounts provided herein include amounts related only to our obligations with respect to the various plans based on actuarial computations and reflect our employee and retiree demographics as described above.

The calculated value method is used to determine the market-related value of the assets held in the trust for purposes of calculating our pension costs. Realized and unrealized gains or losses in the market-related value of assets are included over a rolling four-year period. Each year, 25% of such gains and losses for the current year and for each of the preceding three years is included in the market-related value. Each year, the market-related value of assets is increased for contributions to the plan and investment income and is decreased for benefit payments and expenses for that year.

The fair value method is used to determine the market-related value of the assets held in the trust for purposes of calculating OPEB cost.

Pension Plans and OPEB Plans Investment Strategy and Asset Allocations

Our investment objective for the retirement plans is to invest in a suitable mix of assets to meet the future benefit obligations at an acceptable level of risk, while minimizing the volatility of contributions. Equity securities are held to achieve returns in excess of passive indexes by participating in a wide range of investment opportunities. International equity, real estate securities and credit strategies (high yield bonds, emerging market debt and bank loans) are used to further diversify the equity portfolio. International equity securities may include investments in both developed and emerging international markets. Fixed income securities include primarily corporate bonds from a diversified range of companies, U.S. Treasuries and agency securities and money market instruments. Our investment strategy for fixed income investments is to maintain a high-grade portfolio of securities, which assists us in managing the volatility and magnitude of plan contributions and expense while maintaining sufficient cash and short-term investments to pay near-term benefits and expenses.

The Oncor Retirement Plan’s investments are managed in two pools: one pool associated with the regulated utility service portion of plan obligations related to Oncor’s regulated utility business, and a second pool associated with the service portion of plan obligations not related to Oncor’s regulated utility business. Each pool is invested in a broadly diversified portfolio as shown below. The second pool represents 25% of total investments at December 31, 2023.

The target asset allocation ranges of the pension plans’ investments by asset category are as follows:

	Target Allocation Ranges
Asset Category	Regulated Utility Service Pool	Non-Regulated Service Pool
International equities	8% - 16%	5% - 11%
U.S. equities	17% - 25%	11% - 17%
Real estate	7% - 11%	3% - 7%
Credit strategies	3% - 7%	3% - 7%
Fixed income	48% - 58%	65% - 75%

Our investment objective for the OPEB Plans primarily follows the objectives of the pension plans discussed above, while maintaining sufficient cash and short-term investments to pay near-term benefits and expenses. The actual amounts at December 31, 2023 provided below are consistent with the asset allocation targets.

Expected Long-Term Rate of Return on Assets Assumption

The retirement plans’ strategic asset allocation is determined in conjunction with the plans’ advisors and utilizes a comprehensive Asset-Liability modeling approach to evaluate potential long-term outcomes of various investment strategies. The modeling incorporates long-term rate of return assumptions for each asset class based on historical and future expected asset class returns, current market conditions, rate of inflation, current prospects for economic growth, and taking into account the diversification benefits of investing in multiple asset classes and potential benefits of employing active investment management.

(a)The 2024 expected long-term rate of return for the nonregulated portion of the Oncor Retirement Plan is 5.75%, and for Oncor’s obligations with respect to the Vistra Retirement Plan is 6.29%.

Significant Concentrations of Risk

The plans’ investments are exposed to risks such as interest rate, capital market and credit risks. We seek to optimize return on investment consistent with levels of liquidity and investment risk which are prudent and reasonable, given prevailing capital market conditions and other factors specific to participating employers. While we recognize the importance of return, investments will be diversified in order to minimize the risk of large losses unless, under the circumstances, it is clearly prudent not to do so. There are also various restrictions and guidelines in place including limitations on types of investments allowed and portfolio weightings for certain investment securities to assist in the mitigation of the risk of large losses.

Assumed Discount Rate

For the Oncor Retirement Plan at December 31, 2023, we selected the assumed discount rate using the Aon AA-AAA Bond Universe yield curve, which is based on corporate bond yields and at December 31, 2023 consisted of 1,193 corporate bonds with an average rating of AA and AAA using Moody’s, S&P and Fitch ratings. For Oncor’s obligations with respect to the Vistra Retirement Plan and the OPEB Plans at December 31, 2023, we selected the assumed discount rate using the Aon AA Above Median yield curve, which is based on corporate bond yields and at December 31, 2023 consisted of 509 corporate bonds with an average rating of AA using Moody’s, S&P and Fitch ratings.

Future Pension Plans and OPEB Plans Cash Contributions

Based on applicable minimum funding requirements and the latest actuarial projections, our future funding for the pension plans and the OPEB Plans, is expected to total $91 million and $23 million, respectively, in 2024 and approximately $549 million and $135 million, respectively, in the five-year period 2024 to 2028. We may also elect to make additional discretionary contributions based on market and/or business conditions.

Future Benefit Payments

Estimated future benefit payments to participants are as follows:

	2024		2025		2026		2027		2028		2029-33
Pension plans	$	181	$	184	$	186	$	187	$	188	$	920

Thrift Plan

Our employees are eligible to participate in a qualified savings plan, the Oncor Thrift Plan, which is a participant-directed defined contribution plan subject to the provisions of ERISA and intended to qualify under Section 401(a) of the Code, and to meet the requirements of Code Sections 401(k) and 401(m). Under the plan, employees may contribute, through pre-tax salary deferrals and/or after-tax applicable payroll deductions, a portion of their regular salary or wages as permitted under law. Employer matching contributions are made in an amount equal to 100% of the first 6% of employee contributions for employees who are covered under the Cash Balance Formula of the Oncor Retirement Plan, and 75% of the first 6% of employee contributions for employees who are covered under the Traditional Retirement Plan Formula of the Oncor Retirement Plan. Employer matching contributions are made in cash and may be allocated by participants to any of the plan’s investment options. Our contributions to the Oncor Thrift Plan totaled $29 million, $26 million and $24 million for the years ended December 31, 2023, 2022 and 2021, respectively.

10. RELATED-PARTY TRANSACTIONS

The following represents our significant related-party transactions and related matters.

We are not a member of another entity’s consolidated tax group, but our owners’ federal income tax returns include their portion of our results. Under the terms of a tax sharing agreement among us, Oncor Holdings, Texas Transmission and STH, we are generally obligated to make payments to our owners, pro rata in accordance with their respective membership interests, in an aggregate amount that is substantially equal to the amount of federal income taxes that we would have been required to pay if we were filing our own corporate income tax return. STH will file a combined Texas margin tax return which includes our results and our share of Texas margin tax payments, which are accounted for as income taxes and calculated as if we were filing our own return. See discussion in Note 1 under “Provision in Lieu of Income Taxes.” Under the “in lieu of” tax concept, all in lieu of tax assets and tax liabilities represent amounts that will eventually be settled with our members. In the event such amounts are not paid under the tax sharing agreement, it is probable that these regulatory amounts will continue to be included in Oncor’s rate setting processes.

Amounts payable to (receivable from) members related to income taxes under the agreement and reported on our balance sheet consisted of the following:

Pursuant to the PUCT order in Docket No. 48929 relating to Oncor’s 2019 acquisition of InfraREIT, Inc., we entered into an operation agreement with Sharyland under which we provide certain operations services to Sharyland at cost with no markup or profit. Sempra owns an indirect 50% interest in the parent of Sharyland. Sharyland provided wholesale transmission service to us in the amount of $16 million, $11 million and

$10 million in the years ended December 31, 2023, 2022 and 2021, respectively. We provided certain operation services to Sharyland in the amount of $659,000, $639,000 and $592,000 in the years ended December 31, 2023, 2022 and 2021, respectively.

MANAGEMENT’S ANNUAL REPORT ON

The management of Oncor Electric Delivery Company LLC is responsible for establishing and maintaining adequate internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934) for the company. Oncor Electric Delivery Company LLC’s internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in condition or the deterioration of compliance with procedures or policies.

The management of Oncor Electric Delivery Company LLC performed an evaluation as of December 31, 2023 of the effectiveness of the company’s internal control over financial reporting based on the Committee of Sponsoring Organizations of the Treadway Commission’s (COSO’s) Internal Control - Integrated Framework (2013). Based on the review performed, management believes that as of December 31, 2023, Oncor Electric Delivery Company LLC’s internal control over financial reporting was effective.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Members of Oncor Electric Delivery Company LLC

Opinion on Internal Control over Financial Reporting

We have audited the internal control over financial reporting of Oncor Electric Delivery Company LLC and subsidiaries (the “Company”) as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO). In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by COSO.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB) and in accordance with auditing standards generally accepted in the United States of America, the consolidated financial statements as of and for the year ended December 31, 2023, of the Company and our report, dated February 27, 2024, expressed an unqualified opinion on those financial statements.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management’s Annual Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB and in accordance with auditing standards generally accepted in the United States of America. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Mr. Martin and Mr. Bird were each designated to serve on our board of directors by Sempra (through Oncor Holdings) and Ms. Newell and Mr. Zucchet were each designated to serve on our board of directors by Texas Transmission. Directors designated by Sempra and Texas Transmission are referred to as member directors. Oncor Holdings, at the direction of STIH, has the right, pursuant to the terms of our LLC Agreement, to nominate each Oncor Officer Director, subject to approval of any such nomination by a majority of the Oncor board of directors. Mr. Shapard and Mr. Nye each serve as an Oncor Officer Director.

Our LLC Agreement provides that seven of our directors will be Disinterested Directors under the standards set forth in our LLC Agreement. See “Item 13. Certain Relationships and Related Transactions, and Director Independence—Director Independence” for a discussion of the director qualifications. We have determined that Messrs. Estrada, Gary, Mack, Saenz and Walker and Mses. Keliher and Rodriguez are Disinterested Directors. Disinterested Directors are designated at the direction of the nominating committee of Oncor Holdings’ board of directors subject to the approval by a majority of the Disinterested Directors of Oncor Holdings’ board of directors. The nominating committee of Oncor Holdings is required to consist solely of Disinterested Directors. The Sempra Order and our LLC Agreement provide that the Disinterested Directors of Oncor at the time of the Sempra Acquisition, who are referred to as initial Disinterested Directors, would serve, if willing and able, for a term of three years from the closing of the Sempra Acquisition (subject to continuing to meet the Disinterested Director requirements). Thereafter, the Sempra Order and our LLC Agreement require that two of these initial Disinterested Directors roll off our board of directors beginning March 2021 and continuing every two years until no initial Disinterested Director remains on our board of directors, with the nominating committee of Oncor Holdings (subject to approval by a majority of the Disinterested Directors of the Oncor Holdings board of directors) determining the order of departure of these directors. As a result, two of our initial Disinterested Directors were required to roll off our board of directors prior to March 9, 2023 and two new Disinterested Directors were required to be appointed as their successors. In connection with the requirements of the Sempra Order and our LLC Agreement, on March 7, 2023, William T. Hill, Jr. submitted a letter of resignation and on March 8, 2023, Thomas M. Dunning, submitted a letter of resignation, each resigning from our board of directors effective as of March 8, 2023.

The Oncor Holdings designation was made pursuant to the direction of the Oncor Holdings nominating committee with the approval of a majority of the Disinterested Directors of Oncor Holdings. Our LLC Agreement provides that each Disinterested Director, other than the initial Disinterested Directors, will be appointed for a four-year term, which is able to be renewed for only one additional term of four years, and will be appointed consistent with a mandatory retirement age of 75. To the extent any Disinterested Director is removed, retires or is otherwise unable to or unwilling to serve, a replacement new Disinterested Director will be chosen by the nominating committee of Oncor Holdings subject to approval by a majority vote of the Disinterested Directors of Oncor Holdings’ board of directors. Any change to the size, composition, structure or rights of our board of directors must first be approved by the PUCT.

Our LLC Agreement provides that until March 9, 2028, in order for a current or former officer of Oncor to be eligible to serve as an Oncor Officer Director, the officer cannot have worked for Sempra or any of its subsidiaries or affiliated entities (excluding Oncor Holdings and Oncor) or any other entity with a direct or indirect ownership interest in Oncor or Oncor Holdings in the ten-year period prior to the date on which the officer first became employed by Oncor. In addition to Oncor Holdings’ right to nominate Oncor Officer Directors, Oncor Holdings, at the direction of STIH, has the right to seek the removal of the Oncor Officer Directors, subject to approval by a majority of the Oncor board of directors.

Item 11.EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

Overview

In this Compensation Discussion and Analysis, we describe our executive compensation philosophy and the elements of our executive compensation program. We also discuss how the executive officers named in the Summary Compensation Table (our Named Executive Officers) were compensated in 2023. In 2023, our Named Executive Officers, as well as their current titles, were:

Name	Title
E. Allen Nye, Jr.	Chief Executive (CEO)
Don J. Clevenger	Senior Vice President and Chief Financial Officer
Deborah L. Dennis	Senior Vice President, Chief Customer Officer and Chief HR Officer
James A. Greer	Executive Vice President and Chief Operating Officer
Matthew C. Henry	Senior Vice President, General Counsel and Secretary

Role of the Organization and Compensation Committee

Our board of directors has designated an Organization and Compensation Committee of the board of directors (O&C Committee) to establish, administer, and assess our executive compensation policies, which include participation in various employee benefit programs. The O&C Committee met five times in 2023.

The responsibilities of the O&C Committee include:

Determining and overseeing executive compensation programs, including making recommendations to our board of directors, when and if board of director approval is required, with respect to the adoption, amendment or termination of incentive compensation, equity-based compensation and other executive compensation and benefit plans, policies and practices;

Establishing, reviewing and approving corporate goals and objectives relevant to executive compensation, evaluating the performance of our CEO and other executive officers in light of those goals and objectives and ultimately approving executive compensation based on those evaluations; and

Advising our board of directors with respect to the compensation of our Disinterested Directors and non-executive Chairman of the board of directors.

The O&C Committee conducts reviews of the level of individual compensation elements as well as total direct compensation (base salary, annual incentives and long-term incentives) for our executive officers, from time to time as it deems appropriate. The O&C Committee conducted such compensation reviews in the fourth quarter of 2023. In determining the total direct compensation of our executive officers, the O&C Committee considers the performance and responsibilities of the executives and both the competitive market analysis and peer group comparisons of executive compensation provided by a compensation consultant engaged by the O&C Committee. The O&C Committee evaluates the CEO’s performance and obtains the input of the CEO on the performance of executive officers other than the CEO. The CEO assesses the performance of each executive in light of the executive’s business unit and function and presents a performance evaluation and total direct compensation recommendation for each of these individuals to the O&C Committee. The CEO also reviews and considers the competitive market analysis and peer group comparisons in making his recommendations to the O&C Committee. The O&C Committee determines the total direct compensation, including base salary, annual incentive awards and long-term incentive awards, for each of our executive officers as it deems appropriate.

Following the completion of each fiscal year, the O&C Committee (1) approves corporate goals and objectives under our annual and long-term incentive programs for our executive officers for awards for the current fiscal year, and (2) certifies the performance results for incentive payments for performance periods that ended on December 31 of the previous fiscal year. In connection with the annual determination of the incentive awards to be paid to our executive officers other than the CEO, the CEO conducts an annual performance review of each executive officer and evaluates each executive’s performance for the recently completed fiscal year relative to the corporate goals and objectives for such fiscal year set by the O&C Committee. The CEO then makes recommendations to the O&C Committee with respect to these

114

individuals regarding whether an individual performance modifier should be applied to such executive officer’s annual incentive compensation. The O&C Committee also annually evaluates the CEO’s performance in light of the goals and objectives set by the O&C Committee for the CEO for the previous fiscal year. After considering this evaluation, as well as the CEO’s recommendations with respect to the other executive officers, the O&C Committee determines any individual performance modifiers to be applied to the annual incentive award payout for each executive officer.

Compensation Philosophy

Our compensation philosophy, principles and practices are intended to compensate our executives appropriately for their contribution to the attainment of key strategic objectives and to strongly align the interests of our executives, owners, and customers through both short-term and long-term performance goals. We believe that:

Levels of executive compensation should be based upon an evaluation of the performance of our business (particularly through operational metrics) and the individual executive, as well as a comparison to compensation levels of persons with comparable responsibilities in business enterprises of similar size, scale, complexity, risk, industry and performance to us;

Compensation plans should balance both short-term and long-term objectives; and

The overall compensation program should emphasize variable compensation elements that have a direct link to company and individual performance.

Objectives of Compensation Philosophy

Our compensation philosophy is designed to meet the following objectives:

Attracting and retaining high performers;

Rewarding company and individual performance by providing compensation levels consistent with the level of contribution and degree of accountability;

Aligning performance measures with company goals and allocating a significant portion of compensation to incentive compensation in order to drive the performance of our business;

Basing incentive compensation largely on the satisfaction of company operational metrics with the goal of motivating performance towards improving the services we provide our customers; and

Creating value for our owners and promoting the long-term performance of the company.

Elements of Compensation

In an effort to achieve our compensation objectives, we have established a compensation program for our executives that principally consists of:

Base salary;

Short-term incentives through the opportunity to earn an annual performance bonus pursuant to the Oncor Electric Delivery Company LLC Ninth Amended and Restated Executive Annual Incentive Plan (Executive Annual Incentive Plan);

Long-term incentives through awards under the Oncor Electric Delivery Company LLC Long-Term Incentive Plan as amended and restated effective December 31, 2022 (Long-Term Incentive Plan);

Deferred compensation and retirement plans through (1) the opportunity to participate in a participant-directed defined contribution qualified savings plan (thrift plan) and a salary deferral program (Salary Deferral Program) and receive certain company matching contributions, (2) a defined benefit retirement plan and a supplemental retirement plan, and (3) an employer-paid subsidy for health care coverage upon the executive’s retirement from Oncor for executives hired prior to January 1, 2002;

Perquisites and other benefits;

Contingent payments through an executive change of control policy and an executive severance plan; and

In certain instances, discretionary bonuses and retention agreements.

For more information about the incentive and other benefit plans available to our executives see “—Compensation Elements” below and the compensation tables and the accompanying narratives immediately following this “Compensation Discussion and Analysis.”

Compensation Consultant

The O&C Committee engaged PricewaterhouseCoopers LLP (PricewaterhouseCoopers) as its compensation consultant from 2014 to July 2023 to advise and report to the O&C Committee on executive compensation and certain director fee matters. PricewaterhouseCoopers and its affiliates also provide consulting and related services to Oncor with respect to human resources, tax, internal audit, compliance and other matters. In mid-2023, the O&C Committee initiated a competitive request for proposal process for compensation consultants. Following the completion of that process, the O&C Committee engaged Meridian Compensation Partners, LLC (Meridian) as its new compensation consultant beginning in August 2023 to advise and report on executive compensation and compensation with respect to our Disinterested Directors and non-executive Chairman of the board of directors, including providing an analysis of competitive market survey data and a peer group comparison to the O&C Committee, as discussed in more detail under “—Compensation Benchmarking and Market Data” below. Meridian also provides consulting services to Oncor related to non-executive officer compensation.

Compensation Benchmarking and Market Data

While we try to ensure that the greater part of an executive officer’s compensation is directly linked to the executive’s individual performance and Oncor’s operational performance, we also seek to set our executive compensation program in a manner that is competitive with both the competitive market analysis and peer group comparisons prepared for the O&C Committee by the O&C Committee’s compensation consultant in order to promote retention of key personnel and to attract high-performing executives from outside our company. As a result, the O&C Committee annually conducts a compensation benchmarking review of our executive officers.

October 2022 Competitive Market Analysis and Peer Group Comparison

In the fourth quarter of 2022, the O&C Committee assessed total direct compensation of our executives against a number of companies in the utility industry, including transmission/distribution utilities and fully integrated utilities, using both competitive market survey data and peer group comparisons prepared by PricewaterhouseCoopers. For purposes of the 2022 assessment, PricewaterhouseCoopers completed a competitive market analysis of executive compensation for the O&C Committee in October 2022. This competitive market analysis involved a review of competitive market survey data from a nationally recognized energy services executive compensation report for 2022 using our size (based on our 2021 annual revenues) and our industry (utilities; energy sector), and a review of each of our executives’ total direct compensation against similarly situated executives within that competitive market survey group. For purposes of the competitive market analysis, PricewaterhouseCoopers adjusted the competitive market survey data upward or downward as they deemed appropriate to reflect the increased or decreased scope of duties of certain Oncor executives as compared to similarly situated executives within the competitive market survey group, including upward adjustments to the survey data applied to each of Messrs. Clevenger and Henry and Ms. Dennis to reflect their additional responsibilities versus comparable positions. In addition, to better reflect our competitive position versus the market, the long-term incentive competitive market survey data was adjusted by PricewaterhouseCoopers to include a premium to approximate the value difference after three years between the cash long-term incentives we offer our executives and the equity long-term incentives offered by most of our peers. The competitive market survey data was also aged from the reporting date to January 1, 2023, using an annual rate of 4.0%, which was the projected increase factor for 2022 for officers and executives based on a nationally recognized salary budget survey. The PricewaterhouseCoopers competitive market analysis compared the compensation elements for each of our executives to the 50^th percentile of the adjusted competitive market survey data with respect to base salary, target total cash compensation (base salary and target cash annual incentives) and target total direct compensation (base salary, target cash annual incentives and long-term incentives). The PricewaterhouseCoopers competitive market analysis also compared the target cash annual incentives and long-term incentives for each of our executives to the 50^th and 75^th percentiles of the adjusted competitive market survey data.

In addition to the competitive market analysis for utilities in the national marketplace, PricewaterhouseCoopers also provided publicly available data for a subset of these utilities, a peer group of transmission/distribution utility companies as well as fully integrated utility companies based on relevant industry classification codes and filters identifying companies similar to Oncor based on business operations, revenue, and other objective criteria, including potential competition for talent. PricewaterhouseCoopers recommended keeping the companies from the 2021 peer group for the 2022 peer group. Oncor’s size, based on 2021 revenues, was in the 47^th percentile of this peer group. PricewaterhouseCoopers provided information on base salary, target annual incentives, target total cash compensation, long-term incentives and target total direct compensation with respect to the chief executive officer, chief financial officer, chief operating officer, general

116

counsel and three highest paid executives (excluding the chief executive officer and chief financial officer) at each of the 2022 peer group companies (to the extent such data was available), along with comparisons of each such executive to the comparable Oncor executive using regression analysis based on Oncor’s revenue size, the addition of a premium to reflect the value difference between the cash long-term incentives we offer our executives and the equity long-term incentives offered by most of our peers, and the addition of a premium on the general counsel role to reflect the additional scope of responsibilities held by our general counsel. For purposes of the peer group review, one-time payments granted pursuant to an offer letter and one-time retention bonuses were disregarded. The peer group consisted of 15 companies, all of which were used in PricewaterhouseCoopers’ 2021 study:

Alliant Energy	Cleco Power LLC	IdaCorp Inc.
Ameren Corp.	CMS Energy Corp.	ITC Holdings Corp.
American Electric Power Co., Inc.	Consolidated Edison, Inc.	OGE Energy Corp.
Avangrid Inc.	Evergy Inc.	Pinnacle West Capital
CenterPoint Energy, Inc.	Eversource Energy	Portland General Electric Co.

The O&C Committee reviewed and considered both the 2022 peer group data and the competitive market analysis, along with individual performance and responsibilities, when determining total direct compensation, as well as each element of total direct compensation. For each executive, the O&C Committee targeted total direct compensation, including target payouts under annual and long-term incentive awards, at approximately the 50th percentile of the adjusted competitive market survey data for that executive’s position. With respect to long-term incentives, the O&C Committee also considered the cost of equity differential between Oncor’s long-term incentive program, which offers cash awards, versus equity-based long-term incentive awards, which are more common among the peer group. The competitive market analysis indicated that the aggregate target total direct compensation of certain of our executives (including Messrs. Nye, Greer and Henry) was generally below the 50^th percentile of the adjusted competitive market survey data, with all individual Named Executive Officers within 4% above or 4% below the 50^th percentile.

After consideration of the PricewaterhouseCoopers studies and each executive’s individual performance and responsibilities, in October 2022 the O&C Committee increased the base salaries of all Named Executive Officers effective November 26, 2022. No changes were made to the target annual incentives of our Named Executive Officers under the Executive Annual Incentive Plan or the long-term incentives target percentages for our Named Executive Officers effective January 1, 2023.

October 2023 Competitive Market Analysis and Peer Group Comparison

In the fourth quarter of 2023, the O&C Committee assessed total direct compensation of our executives using a competitive market analysis prepared by Meridian. The competitive market analysis included (i) a review of publicly-available market data from a custom group of peer utilities (peer group comparison), (ii) a review of 2023 survey data from a nationally recognized data provider based on organizations in the energy sector with annual revenues between $3 billion and $6 billion (the energy survey data), and (iii) a review of 2023 survey data from the same nationally recognized data provider based on organizations from all industries with annual revenues between $3 billion and $6 billion (the general industry survey data), and, to the extent available for each, a review of each of our executives’ total direct compensation against similarly situated executives within each survey group.

The approach to the peer group selection was based on (i) global industry classification standards, (ii) companies similar to Oncor based on revenues, assets, operating income and number of employees, and (iii) other operational attributes, including regulated entities, number of customers, number of states serviced, capital expenditures, public pay disclosure and organizational structure. Meridian recommended removing two companies (American Electric Power Co., Inc. and Cleco Power LLC) that were included in our 2022 peer group from the 2023 peer group. In addition, Meridian recommended adding four additional companies to the 2023 peer group (Atmos Energy Corporation, Entergy Corporation, PPL Corporation and Puget Sound Energy). The addition of these new peers adds additional companies similarly-sized to Oncor that represent Oncor’s competition for executive talent. Oncor’s size, based on 2022 revenues, was in the 47^th percentile of this peer group. Meridian provided information on base salary, target annual incentives, target total cash compensation, long-term incentives and target total direct compensation at each of the 2023 peer group companies (to the extent such data was available) with respect to the chief executive officer, chief financial officer, general counsel, and rank matches for the second and fifth highest paid executive officers. Rank matches, reflecting roles at peer group companies similarly situated in terms of being the second highest paid executive, in the case of Mr. Greer, and the fifth highest paid

117

executive, in the case of Ms. Dennis, were used due to the small sample size of reported data for chief operating officer and chief human resources officer roles by our peer group. The peer group consisted of 17 companies for 2023:

Alliant Energy	Consolidated Edison, Inc.	OGE Energy Corp.
Ameren Corp.	Entergy Corporation	Pinnacle West Capital
Atmos Energy Corporation	Evergy Inc.	Portland General Electric
Avangrid Inc.	Eversource Energy	PPL Corporation
CenterPoint Energy, Inc.	IdaCorp Inc.	Puget Sound Energy
CMS Energy Corp.	ITC Holdings Corp.

For purposes of the competitive market analysis, Meridian adjusted the energy survey data and general industry survey data, collectively, the survey data, upward or downward as they deemed appropriate to reflect the increased or decreased scope of duties of certain Oncor executives as compared to similarly situated executives within the applicable survey group, including upward adjustments to the survey data applied to Ms. Dennis and Mr. Henry to reflect their additional responsibilities versus comparable positions. The survey data for all participants was regressed to $5.336 billion in annual revenue and was also aged from the reporting date to January 1, 2024, using an annual rate of 4.0%, which was the projected increase factor for 2024 for officers and executives based on a nationally recognized salary budget survey. The peer group comparison was unadjusted.

The Meridian competitive market analysis compared the compensation elements for each of our executives to the 25^th, 50^th and 75^th percentiles of the adjusted survey data, to the extent available, with respect to base salary, target annual incentives, target total cash compensation (base salary and target annual incentives), long-term incentives and target total direct compensation (base salary, target annual incentives and long-term incentives). The Meridian competitive market analysis also compared Oncor’s compensation that is considered “at-risk” (annual incentives and long-term incentives) to general market data provided by Meridian.

The O&C Committee reviewed and considered the 2023 competitive market analysis, along with individual performance and responsibilities, when determining total direct compensation, as well as each element of total direct compensation. For each executive, the O&C Committee considered total direct compensation, including target payouts under annual and long-term incentive awards, at the 25^th, 50^th and 75^th percentiles of the energy survey data and the peer group comparison, to the extent available, for that executive’s position.

As described further below, after consideration of the Meridian studies and each executive’s individual performance and responsibilities, in October 2023 the O&C Committee increased the base salaries of all Named Executive Officers effective November 26, 2023. In December 2023, the O&C Committee increased short-term and long-term target incentive percentages of all Named Executive Officers for performance periods beginning on or after January 1, 2024, reflecting consideration of the Meridian studies and each executive’s individual performance. These target incentive changes did not impact awards previously granted or awards earned in 2023, including awards payable in 2024.

Compensation Elements

A significant portion of each executive officer’s compensation is variable, at-risk and directly linked to achieving company performance objectives set by the O&C Committee, which are intended to strongly align the interests of our executives, owners, and customers (both our direct customers and the communities we serve) in order to promote the long-term success of our company. Other factors impacting compensation include individual performance, scope of responsibilities, retention risk, and market compensation data. None of these other factors are assigned individual weights, but are considered together. The company has no policies or formula for allocating compensation among the various elements. The following is a description of the principal compensation components provided to our executives.

Base Salary

We believe that base salary should be commensurate with the scope and complexity of each executive’s position, the level of responsibility required, and demonstrated performance. We also believe that a competitive level of base salary is required to attract and retain qualified talent.

As part of its review of total direct compensation for our executive officers, the O&C Committee reviews and determines executive officers’ base salaries periodically as it deems appropriate. The periodic review includes the O&C Committee’s review of the most recent competitive market analysis of our executive compensation and comparison to our

118

peer group. Our CEO also reviews this analysis, along with the performance and level of responsibility of each executive officer, and makes recommendations to the O&C Committee regarding any salary changes for those individuals. The O&C Committee may also approve salary increases as a result of an executive’s performance, promotion or a significant change in an executive’s responsibilities.

The 2023 competitive market analysis prepared by Meridian indicated that the base salary of Ms. Dennis was below the 50th percentile of the adjusted energy survey data for her position. For Ms. Dennis and Mr. Henry, whose roles involve responsibilities in addition to the duties traditionally associated with the chief human resources officer and general counsel, respectively, the energy survey data included the addition of a premium to address their respective additional responsibilities. These additional responsibilities consist of chief customer officer duties for Ms. Dennis and oversight of regulatory affairs, risk, and environmental, social, and governance matters for Mr. Henry. The base salaries of Messrs. Nye, Greer, Clevenger, and Henry were near the 50^th percentile of the adjusted energy survey data for their respective positions. After considering the results of the 2023 competitive market analysis and individual performance and responsibilities, the O&C Committee increased the base salary of each of our Named Executive Officers, effective November 26, 2023, as described below.

Annual Base Salary for Named Executive Officers

The annual base salaries of our Named Executive Officers at December 31, 2023 were as follows:

Name	Current Title	At December 31, 2023 (1)
E. Allen Nye, Jr.	Chief Executive	$1,202,000
Don J. Clevenger	Senior Vice President and Chief Financial Officer	$ 685,000
Deborah L. Dennis	Senior Vice President, Chief Customer Officer and Chief HR Officer	$ 509,000
James A. Greer	Executive Vice President and Chief Operating Officer	$ 697,000
Matthew C. Henry	Senior Vice President, General Counsel and Secretary	$ 684,000

__________

(1)Annual base salaries were increased effective November 26, 2023 as follows: Mr. Nye increased from $1,145,000 to $1,202,000; Mr. Clevenger increased from $652,000 to $685,000; Ms. Dennis increased from $476,000 to $509,000; Mr. Greer increased from $664,000 to $697,000; and Mr. Henry increased from $651,000 to $684,000.

Executive Annual Incentive Plan

The O&C Committee and our CEO are responsible for administering the Executive Annual Incentive Plan. The award targets under the Executive Annual Incentive Plan are established on a company-wide basis and the O&C Committee seeks to set these targets at performance challenging levels. The O&C Committee determines annual target award percentages for executives based on executive responsibilities and performance goals, an evaluation of the most recent competitive market analysis conducted by the O&C Committee’s compensation consultant at such time (with respect to the 2023 plan year, PricewaterhouseCoopers, and the 2024 plan year, Meridian), and, with respect to executives other than our CEO, recommendations from our CEO. In making his recommendations to the O&C Committee regarding target award percentages, our CEO assesses the performance of each executive against the goals of the executive’s business unit and function and reviews the competitive market analysis. Executive Annual Incentive Plan awards are based on a target payout, which is set as a percentage of a participant’s annualized base salary and is based on both the performance of Oncor and individual participant performance. The annual incentive target payout for each executive for 2023 plan year awards was based on the O&C Committee’s review of the executive’s responsibilities and consideration of the 50^th percentile of the target total direct compensation of executives with similar responsibilities from the 2022 competitive market analysis and, where available, peer group comparison provided to the O&C Committee by the O&C Committee’s compensation consultant.

For 2023, the O&C Committee used five metrics to determine a final funding percentage. The metrics the O&C Committee established for 2023 reflect its belief that annual incentives should be based on achievement of metrics that are strategic to the company and also benefit our customers. The purpose of these metrics is to promote enhancement of our services to customers. The table below sets forth these metrics in further detail.

119

Metric	Description	Purpose
Safety	Number of employee injuries using a Days Away, Restricted or Transferred (DART) rate with a modifier for fatalities resulting from a safety violation.	Promotes the health and welfare of our employees. Lowering the number of accidents also reduces our operating costs, which in turn contributes to lower rates for our customers.
Reliability	Non-storm System Average Interruption Duration Index (SAIDI), which measures the average number of minutes electric service is interrupted per customer in a year. Since weather can greatly impact reliability and is outside of our control, the reliability metric measures SAIDI on a non-storm, weather-normalized basis. Our non-storm reliability performance reflects electric service interruptions of one minute or more per customer.	Promotes our commitment to minimizing service interruptions to our customers, as the lower the SAIDI level for the year, the greater our customers’ service level and satisfaction.
Operational Efficiency	Based on the achievement of targeted operation and maintenance expense (O&M) and sales, general and administrative expense (SG&A) levels determined on a per customer cost basis.	Promotes lower rates for our customers by keeping O&M and SG&A low. For executives, this metric also promotes operating within annual O&M and SG&A budgets.
Infrastructure Readiness	Measured by a metric based on capital expenditure per three-year average kW peak; expressed as a cumulative percentage.	Promotes enhanced service to our customers by focusing on the improvement of our facilities through achievement of the capital plan. For executives, this metric also promotes operating in a disciplined fashion to achieve the capital expenditure budget.
Net Income Growth	Measures the actual percentage of net income growth on a weather-normalized basis, excluding certain items outside of the ordinary course of business	Promotes financially disciplined growth across our company.

Safety and reliability metrics are measured based on company performance as compared generally to certain utility industry operating companies, operational efficiency is measured based on operating within the annual O&M and SG&A budgets, and infrastructure readiness is measured based on making the requisite capital expenditures per kW in accordance with the budgeted amount. The O&C Committee set the safety and reliability performance threshold and superior levels as amounts to be calculated based on industry performance in order to better accomplish Oncor’s goal of being an industry leader in these areas, with an aspirational safety goal set to reflect goals management would like the company to strive to achieve. The O&C Committee included a net income growth metric for 2023 measuring the actual percentage of net income growth (weather normalized and excluding certain items outside of the ordinary course of business as approved by the O&C Committee) during the year, using the adjusted net income for the 2022 fiscal year as the baseline value and the adjusted net income for the 2023 fiscal year as the ending value. The net income metric promotes financially disciplined growth across our company and is sometimes referred to as a net income growth adder. For additional information regarding the weighting of these metrics, see the narrative immediately following the Grants of Plan-Based Awards – 2023 table below.

For 2023, the final funding percentage was 132.8% based on the performance levels achieved for these metrics. For more information on this calculation and the performance under each metric, see the narrative immediately following the Grants of Plan-Based Awards – 2023 table below.

To calculate an executive officer’s actual award amount, the executive officer’s target award, which is computed as a percentage of annualized base salary, is multiplied by the final funding percentage and any individual performance modifier the O&C Committee elects to apply to an executive. An individual performance modifier is based on reviews and evaluations of the executive officer’s performance by the CEO and the O&C Committee (or solely the O&C Committee in

120

the case of our CEO) and may adjust an award upward or downward. The individual performance modifier is determined on a subjective basis. Factors used in determining individual performance modifiers may include new or unexpected responsibilities, company achievement of operational or other measures, company objectives, individual management and other goals, specific job objectives and competencies, the demonstration of team building and support attributes and general demeanor and behavior. The CEO and the O&C Committee (or solely the O&C Committee in the case of our CEO) do not assign these factors individual weights, but consider them together. Each executive officer’s individual performance modifier is set by the O&C Committee within a range determined in its discretion. The O&C Committee did not apply any individual performance modifiers to Named Executive Officers for 2023 plan year awards. The final funding percentage for awards under the plan cannot exceed 150% for 2023 plan year awards, and 200% for plan years beginning in 2024. It is the intent of the O&C Committee to administer the plan so that application of any individual performance modifiers (which under the plan may be plus or minus 50%) would not result in payouts of more than 150% of target award for 2023 plan year awards and 200% for 2024 plan year awards. However, the O&C Committee has discretion in how it administers the plan and could adjust payout maximums as it deems necessary.

The following table provides a summary of the 2023 targets and actual awards for each Named Executive Officer. All awards under the Executive Annual Incentive Plan are made in the form of lump sum cash payments to participants by March 15 of the year following the plan year to which the award relates.

2023 Annual Incentives (Payable in 2024) for Named Executive Officers

Name	Target Payout Opportunity (% of Base Salary)	Target Award ($ Value)	Actual Award ($)(1)	Actual Award (% of Target)
E. Allen Nye, Jr.	100%	1,149,750	1,526,868	132.8%
Don J. Clevenger	65%	425,587	565,180	132.8%

James A. Greer	65%	433,387	575,538	132.8%
Matthew C. Henry	65%	424,937	564,316	132.8%

__________

(1)Actual awards reflect the applicable target award multiplied by the final funding percentage of 132.8%. The O&C Committee did not apply any individual performance modifiers to Named Executive Officers for 2023 plan year awards.

Long-Term Incentives

The purpose of our long-term incentive program, which currently consists of the Long-Term Incentive Plan, is to promote the long-term interests and growth of Oncor by attracting and retaining management and other key personnel. Our long-term incentive program was developed to enable us to be competitive in our compensation practices. It was also developed to reflect our belief that the opportunity to benefit from the positive long-term performance of the company motivates our management to work towards the long-term success of our business and align management’s interests with those of our customers and owners.

The Long-Term Incentive Plan encourages retention of executive officers and other key employees by stipulating performance periods of generally 36 months. We believe that these multi-year performance periods encourage participants to strive for the long-term, sustained success of the company. The nature of the performance targets also ensures that participants strive towards the applicable performance goals.

Our board of directors delegated administration of the Long-Term Incentive Plan to the O&C Committee. Our executive officers and any other key employees of the company or its subsidiaries designated by the O&C Committee are eligible to participate. The plan provides for cash awards to be paid after completion of a performance period based on achievement of certain stated performance goals. A performance period under the Long-Term Incentive Plan is the 36-month period beginning each January 1, unless otherwise determined by the O&C Committee in its sole discretion. The initial participants for each performance period shall be determined by the O&C Committee within a reasonable period of time after the commencement date of a performance period, but in no event later than six months after the commencement date of such performance period; although additional participants for a performance period may be determined by the O&C Committee after the selection of initial participants for that performance period. Performance goals consist of one or more specific performance objectives established by the O&C Committee in its discretion within a reasonable period of time after the commencement date of a performance period, but in no event later than six months after the commencement of the applicable performance period. Performance goals may be designated with respect to the company as a whole or one or more operating units. Performance goals may also be determined on an absolute basis or on the basis of internal goals,

121

levels attained in prior years, other companies or indices, or as ratios expressing relationships between two or more performance goals. For 2023 grants, the O&C Committee set the performance targets on a company-wide basis and at levels it believes are performance challenging.

The long-term incentive target payout for each executive for awards granted in 2023 was set so that the target total direct compensation was near the 50th percentile of the target total direct compensation for executives with similar responsibilities among the 2022 competitive market analysis group (with a 25% premium included in the 2022 competitive market survey data to reflect the approximate value difference between our cash grants and the long-term equity grants issued by most of our peer group).

The O&C Committee determined that the performance goals used for the Long-Term Incentive Plan awards granted in 2023 for the 2023-2025 performance period consist of: (1) the aggregate weighted operational performance goal percentage consisting of (a) a safety metric based on the number of employee injuries using a DART rate with a modifier for fatalities as a result of a safety violation, and (b) a reliability metric measured by non-storm SAIDI, added to (2) a net income growth metric measuring the actual percentage of net income growth (weather normalized and excluding certain items outside of the ordinary course of business as approved by the O&C Committee) during the performance period, using the adjusted net income for the 2022 fiscal year as the baseline value and the adjusted net income of the final year of the three year performance period as the ending value. The safety and reliability metrics are sometimes referred to as the operational metrics or operational performance goals, and the net income growth metric is sometimes referred to as the net income growth adder. For additional information regarding the weighting of the operational metrics, see the narrative immediately following the Grants of Plan-Based Awards – 2023 table below.

The O&C Committee set the safety and reliability performance threshold and superior levels based on industry performance, with an aspirational safety goal set to reflect management’s goals, as it believed performance over the measurement period for those metrics is consistent with the company’s strategic objectives. The achievement of threshold, superior and/or aspirational levels, where applicable, results in funding for a specific operational metric of 50%, 150% and 200%, respectively. Once the threshold level has been achieved, actual results between each level result in a funding percentage based on the percentage of the next, higher level achieved, determined on a straight-line interpolation basis. Based on the weighting for each of the safety and reliability metric, an aggregate weighted operational performance goal percentage is determined.

The final funding percentage for long-term incentive awards granted in 2023 is the sum of the aggregate weighted operational performance goal percentage and the net income growth adder. The amount of each Long-Term Incentive Plan award granted is then determined based on the product of the final funding percentage, multiplied by the target opportunity dollar amount stated in each individual award letter.

The plan also gives the O&C Committee the discretion to adjust long-term awards to prevent unintended dilution or enlargement as a result of certain extraordinary events. For each operational metric, the O&C Committee may set threshold, superior and aspirational levels of attainment and the manner of calculating the award amounts at each level (such as a specified dollar amount or a percentage or multiple of base salary).

For a more detailed description of the Long-Term Incentive Plan, including the long-term incentive awards granted in 2021 and the actual performance levels achieved for the 2021-2023 performance period, refer to the narrative that follows the Grants of Plan-Based Awards – 2023 table below.

Long-Term Incentive Awards Granted in 2021 with a 2021 – 2023 Performance Period (Payable in 2024)

In February 2024, the O&C Committee certified the level of attainment of performance goals established for long-term incentive awards granted in 2021 with a performance period that ended on December 31, 2023. Pursuant to the terms of the 2021 long-term incentive awards, the amount of each award was determined based on the product of the final funding percentage for long-term incentive awards granted in 2021 certified by the O&C Committee in February 2024 and the target opportunity dollar amount stated in the award agreement granted to each individual. The final funding percentage is the sum of the aggregate weighted operational performance goal percentage and the net income growth adder. For long-term incentive awards granted in 2021, this final funding percentage was 138.2%, resulting in the long-term incentive awards as set forth below for the Named Executive Officers. See “—Compensation Tables—Long-Term Incentive Plan—2021 Grants of Long-Term Incentive Awards” for a discussion of the performance metrics and the performance goals achieved for the 2021-2023 performance period that were certified by the O&C Committee.

2021 - 2023 Performance Period Long-Term Incentive Awards (Payable in 2024) for Named Executive Officers in Office at December 31, 2023

Don J. Clevenger	1,390,638

James A. Greer	1,511,010
Matthew C. Henry	1,177,862

In accordance with the terms of the plan, these amounts will be paid to the Named Executive Officers prior to April 1, 2024.

For a more detailed description of the Long-Term Incentive Plan, refer to the narrative that follows the Grants of Plan-Based Awards – 2023 table below.

Deferred Compensation and Retirement Plans

Our executive compensation package includes the ability to participate in the Salary Deferral Program, Oncor’s thrift plan, the Oncor Retirement Plan and the Supplemental Retirement Plan, and, for executives hired before January 1, 2002, subsidized retiree health care coverage. We believe that these programs, which are common among companies in the utility industry, are important to attract and retain qualified executives.

Salary Deferral Program

Oncor executive officers are eligible to participate in a Salary Deferral Program that allows employees to defer a portion of their salary and annual incentive award and to receive a matching award based on their salary deferrals. Executives can currently defer up to 50% of their base salary and up to 85% of any annual incentive award. At the executive officer’s option, the deferral period can be set for seven years, until retirement or a combination of both. Oncor generally matches 100% of deferrals up to 8% of base salary deferred under the program. Oncor does not match deferred annual incentive awards. Matching contributions vest at the earliest of seven years after the deferral date, termination without cause, retirement at the age of 62 or later, death, disability or termination for good reason following a change in control of Oncor (as defined in the Salary Deferral Program). The program encourages employee retention as, generally, participants who terminate their employment with us prior to the seven-year vesting period forfeit our matching contribution to the program.

123

Additionally, Oncor, at the direction of the O&C Committee, can make additional discretionary contributions into a Salary Deferral Program participant’s account. Discretionary contributions made into a Salary Deferral Program participant’s account by Oncor vest as determined by the O&C Committee.

Refer to the narrative that follows the Nonqualified Deferred Compensation – 2023 table below for a more detailed description of the Salary Deferral Program.

Thrift Plan

All eligible employees of Oncor may contribute a portion of their regular salary or wages to the thrift plan and Oncor matches a portion of an employee’s contributions. This matching contribution is 75% of the employee’s contribution up to 6% of the employee’s base salary for employees covered under the traditional defined benefit component of the Oncor Retirement Plan, and 100% of the employee’s contribution up to 6% of the employee’s base salary for employees covered under the cash balance component of the Oncor Retirement Plan. All matching contributions are invested in thrift plan investments as directed by the participant and are immediately vested. For a more detailed description of the thrift plan, see Note 9 to Financial Statements.

Retirement Plan

All Oncor employees are eligible to participate in the Oncor Retirement Plan, which is qualified under applicable provisions of the Code. The Oncor Retirement Plan contains both a traditional defined benefit component and a cash balance component. Effective January 1, 2002, the defined benefit plan changed from a traditional final average pay design to a cash balance design. This change was made to better align the retirement program with competitive practices. All participants were extended an opportunity to remain in the traditional program component or transition to the cash balance component. Ms. Dennis and Mr. Greer elected to remain in the traditional program. All employees employed after January 1, 2002 who have completed one year of service with the company are eligible to participate only in the cash balance component. As a result, Messrs. Nye, Clevenger, and Henry participate under the cash balance component. For a more detailed description of the Oncor Retirement Plan, refer to the narrative that follows the Pension Benefits table below and Note 9 to Financial Statements.

Supplemental Retirement Plan

Oncor executives participate in the Supplemental Retirement Plan. The Supplemental Retirement Plan provides for the payment of retirement benefits that:

would otherwise be capped by the Code’s statutory limits for qualified retirement plans;

include Executive Annual Incentive Plan awards in the definition of earnings (for participants in the traditional program component only); and/or

Oncor is obligated to pay under contractual arrangements.

For a more detailed description of the Supplemental Retirement Plan, refer to the narrative that follows the Pension Benefits table below.

Retiree Health Care

Employees hired by Oncor (or a predecessor) prior to January 1, 2002 are generally entitled to receive an employer-paid subsidy for retiree health care coverage upon their retirement from Oncor. As such, Ms. Dennis and Mr. Greer will be entitled to receive a subsidy from Oncor for retiree health care coverage upon their retirement from Oncor. Messrs. Nye, Clevenger, and Henry were hired after January 1, 2002 and are not eligible for the employer subsidy.

Perquisites and Other Benefits

Perquisites provided to our executive officers are intended to serve as part of a competitive total compensation program and to enhance our executives’ ability to conduct company business. Perquisites do not include personal use of company property or services for which we are reimbursed for the incremental cost to the company of personal use. In addition, Oncor offers its executive officers the ability to participate in benefit plans for medical, dental and vision

124

insurance, group term life insurance and accidental death and disability insurance, as well as certain other health and welfare benefits, which are generally made available to all employees at the company. We also provide automatic medical contributions of up to $500 for any employee who participates in an Oncor medical plan option, as well as wellness incentives for employees and their spouses completing certain health and wellness-related activities and challenges, up to an aggregate amount of $2,300 in 2023. These contributions and wellness incentives are made available to all employees at the company and as a result are not included in the Summary Compensation Table.

The following is a summary of benefits offered to our executive officers that are not available to all employees. For a description of the total incremental cost to the company of perquisites for each of our Named Executive Officers, refer to Footnote 3 in the Summary Compensation Table below.

Executive Financial Planning: All executive officers are eligible to receive executive financial planning services. These services are intended to support them in managing their financial affairs, which we consider especially important given the high level of time commitment and performance expectation required of our executives. Furthermore, these services help ensure greater accuracy and compliance with individual tax regulations.

Executive Physical Health Exam: All executive officers are also eligible to receive an annual physical examination. We recognize the importance of the health of our senior management team and the vital leadership role they play in directing and operating the company. Our executive officers are important assets of the company and this benefit is designed to help ensure their health and long-term ability to serve the company.

Country Club/Luncheon Club Membership: Certain executive officers are entitled to reimbursement of country club or luncheon club memberships if the company determines that a business need exists for the executive’s memberships, as such clubs provide those officers with a setting for cultivating business relationships and interacting with key community leaders and officials.

Travel and Security: We may pay travel and security expenses for executives related to service on certain third-party boards of directors or, in rare instances of personal travel or personal security, when we believe necessary for the health, safety and welfare of the executive. These expenses could include personal security, including at their personal residence, and non-commercial aircraft flights when we deem there to be a heightened safety or security risk and/or to enhance an executive’s ability to conduct Oncor business. The incremental cost to Oncor of personal security consists of actual invoiced amounts to Oncor for security provided to the executives. The incremental cost to Oncor of non-commercial flights consists of actual invoiced incremental costs for each flight pursuant to Oncor’s contracts with non-commercial aircraft providers minus any amounts reimbursed or reimbursable by the executive or a third party. From time to time an executive’s spouse and/or children may accompany the executive on a business trip. To the extent the spouse’s travel results in an incremental cost to the company, we may pay the incremental costs for the executive’s spouse to travel with the executive, if their presence contributes to the business purpose. However, any incremental costs incurred by Oncor with respect to expenses for an executive’s children to accompany the executive must be fully reimbursed by the executive.

Event Tickets and Recreational Activities: We lease a suite at a sports arena and purchase sponsorships and season and other tickets to sporting, entertainment, and cultural events for business purposes. From time to time, employees, including our executive officers, may have personal use of the suite and/or these tickets, and in most instances such personal use results in no incremental cost to Oncor. In limited instances we may pay the incremental costs associated with personal use of additional tickets or other costs associated with sporting, entertainment and cultural events outside of our existing suite lease, sponsorship, or season ticket arrangements. In limited situations we may also reimburse certain executives for personal recreational activities.

Compensatory Agreements and Discretionary Bonuses

The O&C Committee has from time to time approved retention and performance bonus agreements for certain executives. No such agreements were in effect during 2023. In addition to the Executive Annual Incentive Plan and the Long-Term Incentive Plan, the O&C Committee also has the ability to award discretionary bonuses to executives in its discretion to recognize individual achievements. No such discretionary bonuses were awarded to our Named Executive Officers with respect to performance for the year ended December 31, 2023.

Contingent Payments

Change in Control Policy

Oncor maintains an Amended and Restated Executive Change in Control Policy, as amended from time to time (Change in Control Policy).

The Change in Control Policy provides for the payment of transition benefits to eligible executives if the executive is terminated without cause or resigns for good reason within 24 months following a change in control.

Refer to “—Potential Payments upon Termination or Change in Control—Change in Control Policy” for the definition of the terms “change in control,” “without cause” and “good reason” as used in the Change in Control Policy.

We believe these payments, to be triggered upon meeting the criteria above, provide incentive for executives to fully consider potential changes that are in the best interest of Oncor and our owners, even if those changes would result in the executives’ termination. We also believe it is important to have a competitive change in control program to attract and retain the caliber of executives that our business requires and to foster an environment of relative security within which we believe our executives will be able to focus on achieving company goals.

Refer to “—Potential Payments upon Termination or Change in Control—Change in Control Policy” for detailed information about payments and benefits that our executive officers are eligible to receive under the Change in Control Policy.

128

Severance Plan

Oncor also makes available a Severance Plan (Severance Plan) to provide certain benefits to eligible executives. The purpose of the Severance Plan is to provide benefits to eligible executives who are not eligible for severance pursuant to another plan or agreement (including an employment agreement) and whose employment is involuntarily terminated for reasons other than:

Cause (as defined in the Severance Plan);

Disability of the employee, if the employee is a participant in our long-term disability plan; or

A transaction involving the company or any of its affiliates in which the employee is offered employment with a company involved in, or related to, the transaction.

We believe it is important to have a severance plan in place to attract and retain the caliber of executives that our business requires and to foster an environment of relative security within which we believe our executives will be able to focus on achieving company goals. Refer to “—Potential Payments upon Termination or Change in Control” for detailed information about payments and benefits that our executive officers are eligible to receive under the Severance Plan.

________________

(1)The amounts reported reflect the threshold, target, and maximum amounts available under the Executive Annual Incentive Plan. The O&C Committee set performance levels and metrics for the plan and individual target amounts in April 2023 and final award payout amounts were determined by the O&C Committee in February 2024. The actual awards for the 2023 plan year will be paid in March 2024 and are reported in the Summary Compensation Table under the heading “Non-Equity Incentive Plan Compensation.” Threshold payout amounts for the Executive Annual Incentive Plan reflect the minimum final funding percentage of 50% multiplied by the target award. Maximum payout amounts for the Executive Annual Incentive Plan reflect a final funding percentage of 150% multiplied by the target award. The O&C Committee did not apply any individual performance modifiers to Named Executive Officers for 2023 plan year awards. The Executive Annual Incentive Plan provides that the final funding percentage for awards under the plan cannot exceed 150%. It is the intent of the O&C Committee to administer the plan so that application of any individual performance modifiers (which under the plan may be plus or minus 50%) would not result in payouts of more than 150% of target award. However, the O&C Committee has discretion in how it administers the plan and could adjust payout maximums as it deems necessary.

(2)The amounts reported reflect the threshold, target, and maximum amounts available for award grants made in 2023 under the Long-Term Incentive Plan. Target amounts for each Named Executive Officer were determined by the O&C Committee in April 2023 and any final awards will be payable on or before April 1, 2026 based on achievement of performance goals for the 2023-2025 performance period, as discussed in more detail below under “—Long-Term Incentive Plan.” Under the Long-Term Incentive Plan, threshold payout amounts reflect the minimum final funding percentage of 50% multiplied by the target award. Under the Long-Term Incentive Plan, maximum payout amounts are limited to 150% of the target award. Actual awards for the 2021-2023 performance period will be paid on or before April 1, 2024 and are reported in the Summary Compensation Table under the heading “Non-Equity Incentive Plan Compensation.”

Executive Annual Incentive Plan 2023 Awards

The Executive Annual Incentive Plan is a cash bonus plan intended to provide a performance-based annual award for the successful attainment of certain annual performance goals and business objectives that are established by the O&C Committee. Officers of the company and other specified key employees are eligible to participate in the Executive Annual Incentive Plan provided they are employed by us for a period of at least three full months during a January 1 to December 31 plan year. The O&C Committee and our CEO are responsible for administering the Executive Annual Incentive Plan. Participants who die, become disabled or retire during a plan year are eligible to receive prorated awards under the plan for that plan year provided they completed at least three full months of employment in such plan year.

For 2023, the O&C Committee used the five metrics set forth below to determine a final funding percentage. The metrics the O&C Committee established for 2023 reflect its belief that annual incentives should be based on achievement of metrics that are strategic to the company and also benefit our customers. The purpose of these metrics is to promote enhancement of our services to customers. The table below sets forth these metrics in further detail.

Metrics	Description
Safety	Number of employee injuries using a DART rate with a modifier for fatalities resulting from a safety violation
Reliability	Non-storm SAIDI, which measures the average number of minutes electric service is interrupted per customer in a year on a non-storm, weather normalized basis
Operational Efficiency	Based on the achievement of targeted O&M and SG&A levels determined on a per customer cost basis
Infrastructure Readiness	Measured by a metric based on capital expenditure per three-year average kW peak; expressed as a cumulative percentage
Net Income Growth	Measures the actual percentage of net income growth on a weather-normalized basis, excluding certain items outside of the ordinary course of business

For further information on the metrics, see “—Compensation Elements—Executive Annual Incentive Plan.”

The O&C Committee determined the weighting of each of those metrics within the final funding percentage and, where applicable, the threshold, target, superior, and/or aspirational performance goals for each metric. The achievement of certain threshold, target, superior and aspirational performance levels, where applicable, results in funding for a specific metric of 50%, 100%, 150%, and 200%, respectively. For determining the achievement of the metrics in the foregoing manner, failure to achieve the threshold level, if applicable, for any metric results in 50% funding for that specific metric. Once the threshold level has been achieved, actual results between each level result in a funding percentage based on the percentage of the next, higher level achieved, determined on a straight-line interpolation basis (up to 150% for achievement of the superior performance level and, where applicable, 200% for achievement of the aspirational performance level). The O&C Committee included the net income growth metric measuring the actual percentage of net income growth (weather normalized and excluding certain items outside of the ordinary course of business as approved by the O&C Committee) during the year, using the adjusted net income for the 2022 fiscal year as the baseline value and the adjusted net income of 2023 fiscal year as the ending value. The net income metric promotes financially disciplined growth across our company. The Executive Annual Incentive Plan provides that the final funding percentage will not be greater than 150% nor less than 50%. It is the intent of the O&C Committee to administer the Executive Annual Incentive Plan so that application of any individual performance modifiers (which under the plan may be plus or minus 50%) would not result in payouts of more than 150% of target award. However, the O&C Committee has discretion in how it administers the Executive Annual Incentive Plan and could adjust payout maximums as it deems necessary.

For 2023, the weighting, actual results and funding percentages under the Executive Annual Incentive Plan were as follows:

Goal	Weighting		Threshold(1)		Target(2)		Superior(3)	Aspirational(4)	Actual Results	Funding Percentage(5)
Safety
DART(6)	40%		0.92		N/A		0.32	0.00	0.35	58.0%
Reliability (measured in minutes)
Non-storm SAIDI (minutes)(7)	40%		96.3		N/A		64.8	N/A	70.0	53.4%
Operational Efficiency – O&M Cost Per Customer (measured in $ per customer)
O&M and SG&A Per Customer(8)	10%		$220.85		$216.61		<=$212.36	N/A	$219.27	6.9%

				Final Funding Percentage							132.8%

________________

(1)Achievement up to the threshold metric level results in funding of 50% of the available funding percentage for that specific metric.

(2)Achievement of the target metric level results in funding of 100% of the available funding percentage for that specific metric.

(3)Achievement of the superior metric level results in funding of 150% of the available funding percentage for that specific metric.

(4)Achievement of the aspirational metric level results in funding of 200% of the available funding percentage for that specific metric.

(5)Funding percentage is calculated using actual results and taking into account any applicable modifiers.

(6)DART threshold, superior and aspirational performance goals were set by the O&C Committee in April 2023 as industry average, industry top quartile, and 0.00, respectively. In February 2024, the O&C Committee certified the threshold and superior performance goal amounts, with the amounts being calculated based on a projected linear trend utilizing certain industry DART rates for 2018-2022.

(7)Non-storm SAIDI threshold and superior goals were set by the O&C Committee in April 2023 as the Oncor service area 2023 PUCT reliability standard in accordance with 16 Texas Administrative Code § 25.52 and the midpoint between the 2023 top quartile and 2023 top decile industry non-storm SAIDI performance, respectively. In February 2024, the O&C Committee certified the threshold and superior performance goal amounts, with the superior amount being calculated based on a projected linear trend utilizing certain industry non-storm SAIDI performance for 2018-2022.

(8)In its calculations of this metric, the O&C Committee excluded from both goals and results regulatory mandated cost of service expenses, energy efficiency expenses, third-party network transmission fees (which are recovered through tariff adjustments), excess costs of grid studies and services (which are recovered from requesting third parties), and a one-time write-off resulting from the PUCT’s final order in our comprehensive base rate review.

(9)For purposes of the net income growth adder, the 2022 baseline set by the O&C Committee was our 2022 net income adjusted for weather and excludes certain pension and OPEB costs, special project costs, certain spending that was accelerated into 2022 to offset expense pressure anticipated in 2023 and the tax effect of certain adjusted items. The 2023 net income approved by the O&C Committee was adjusted for weather, excludes certain pension and OPEB costs and a one-time write-off resulting from the PUCT’s final order in our comprehensive base rate review, and includes a downward adjustment to reflect the effects of an initiative to accelerate spending in 2022 to offset expense pressure in 2023.

To calculate an executive officer’s actual award amount, the executive officer’s target award, which is computed as a percentage of annualized base salary, is multiplied by the final funding percentage and any individual performance modifier the O&C Committee elects to apply to an executive. An individual performance modifier is based on reviews and evaluations of the executive officer’s performance by the CEO and the O&C Committee (or solely the O&C Committee in the case of our CEO) and may adjust an award upward or downward. The individual performance modifier is determined on a subjective basis. Factors used in determining individual performance modifiers may include new or unexpected responsibilities, company achievement of operational measures, company objectives, individual management and other goals, specific job objectives and competencies, the demonstration of team building and support attributes and general demeanor and behavior. The CEO and the O&C Committee (or solely the O&C Committee in the case of our CEO) do not assign these factors individual weights, but consider them together. Each executive officer’s individual performance modifier is set by the O&C Committee within a range determined in its discretion. The O&C Committee did not apply any individual performance modifiers to Named Executive Officers for 2023 plan year awards.

133

Long-Term Incentive Plan

The Long-Term Incentive Plan is intended to promote the long-term interests and growth of Oncor by attracting and retaining management and other key personnel. Administration of the Long-Term Incentive Plan has been delegated to the O&C Committee by our board of directors. Our executive officers and any other key employees of the company or its subsidiaries designated by the O&C Committee are eligible to participate. The plan provides for cash awards to be paid after completion of a performance period based on achievement of certain stated performance goals. A performance period under the Long-Term Incentive Plan is the 36-month period beginning each January 1, unless otherwise determined by the O&C Committee in its sole discretion. The initial participants for each performance period shall be determined by the O&C Committee within a reasonable period of time after the commencement date of a performance period, but in no event later than six months after the commencement date of such performance period; although additional participants for a performance period may be determined by the O&C Committee after the selection of initial participants for that performance period. Performance goals consist of one or more specific performance objectives established by the O&C Committee in its discretion within a reasonable period of time after the commencement date of a performance period, but in no event later than six months after the commencement of the applicable performance period. Performance goals may be designated with respect to the company as a whole or one or more operating units. Performance goals may also be determined on an absolute basis or on the basis of internal goals, levels attained in prior years, other companies or indices, or as ratios expressing relationships between two or more performance goals.

2023 Grants of Long-Term Incentive Awards

The O&C Committee determined that the performance goals used for the Long-Term Incentive Plan awards granted in 2023 for the 2023-2025 performance period consist of: (1) the aggregate weighted operational performance goal percentage consisting of (a) a safety metric based on the number of employee injuries using a DART rate with a modifier for fatalities as a result of a safety violation, and (b) a reliability metric measured by non-storm SAIDI, added to (2) a net income growth metric measuring the actual percentage of net income growth (weather normalized and excluding extraordinary items outside of the ordinary course of our business as approved by the O&C Committee) during the performance period, using the adjusted net income for the 2022 fiscal year as the baseline value and the adjusted net income of the final year of the three year performance period as the ending value.

134

The safety metric promotes the health and welfare of our employees, and lowering the number of accidents also reduces our operating costs, which in turn contributes to lower rates for our customers. The reliability metric promotes our commitment to minimizing service interruptions to our customers, as the lower the SAIDI level for the year, the greater our customers’ service level and satisfaction. The net income growth adder serves to measure our company growth over the performance period. The safety and reliability metric performance achievement are each subject to a 45% weighting, and then added to the actual net income growth adder percentage, as set forth below.

2023 - 2025 Performance Period (awards granted in 2023, payable in 2026)
Weighting	Performance Metric	Performance Goal(1)(2)
45%	Safety – measured by DART (average rate)	Threshold:	Industry Average
		Superior:	Industry Top Quartile
		Aspirational:	0.00
45%	Reliability - measured by non-storm SAIDI (minutes)	Threshold:	Oncor’s PUCT System Reliability Standard –288.9
		Superior:	Midpoint between Top Quartile and Top Decile SAIDI
		Aspirational:	N/A
Plus:
Actual %	Net Income Growth Adder – Growth Rate ‘22-‘25(3)
		2022 Baseline:	$844.3 million

__________

(1)For the years 2023 and 2024 in the performance period, industry performance will be determined by the O&C Committee using industry performance data for each respective year. For 2025, industry performance will be calculated based on a projected linear trend utilizing industry rates for 2020-2024.

(2)The achievement of threshold, superior and/or aspirational levels, where applicable, results in funding for a specific operational metric of 50%, 150% and 200%, respectively.

(3)The net income growth adder is calculated as the actual percentage in net income growth from the 2022 baseline through 2025, weather-normalized and excluding extraordinary items outside of the ordinary course of our business as approved by the O&C Committee. The 2022 net income set by the O&C Committee was adjusted for weather and excludes certain pension and OPEB costs, special project costs, certain spending that was accelerated into 2022 to offset expense pressure anticipated in 2023 and the tax effect of certain adjusted items.

The final funding percentage for long-term incentive awards granted in 2023 is the sum of the aggregate weighted operational performance goal percentage and the net income growth adder percentage. The amount of each Long-Term Incentive Plan award is then determined based on the product of the final funding percentage, multiplied by the target opportunity dollar amount stated in each individual award letter.

Certification of performance goal amounts and performance goal achievement will be determined by the O&C Committee in the first quarter of 2026.

2021 Grants of Long-Term Incentive Awards

The O&C Committee determined that the performance goals used for the Long-Term Incentive Plan awards granted in 2021 for the 2021-2023 performance period consist of: (1) the aggregate weighted operational performance goal percentage consisting of (a) a safety metric based on the number of employee injuries using a DART rate with a modifier for fatalities as a result of a safety violation, and (b) a reliability metric measured by non-storm SAIDI, added to (2) a net income growth metric measuring the actual percentage of net income growth (weather normalized and excluding extraordinary items outside of the ordinary course of business as approved by the O&C Committee) during the performance period, using the adjusted net income for the 2020 fiscal year as the baseline value and the adjusted net income of the final year of the three year performance period as the ending value.

In February 2024, the O&C Committee certified the performance goal amounts and the level of attainment of performance goals established for long-term incentive awards granted in 2021 with a performance period that ended on

135

December 31, 2023. The performance goals achieved for the 2021-2023 performance period was certified by the O&C Committee as follows:

2021 - 2023 Performance Period (awards granted in 2021, payable in 2024)
Weighting	Performance Metric	Performance Goal(3)		Actual	Achievement(4)
45%	Safety – measured by DART; (average rate)(1)	Threshold:	0.89	0.32	68.2%
		Superior:	0.33
		Aspirational:	0.00
45%	Reliability - measured by non-storm SAIDI (minutes)(2)	Threshold:	288.9	223.5	54.6%
		Superior:	197.4
		Aspirational:	N/A
Plus:
Actual %	Net Income Growth Adder – Growth Rate ‘20-‘23(5)
		2020 Baseline:	$754.8 million	$870.8	15.4%
Final Funding Percentage					138.2%

__________

(1)DART threshold, superior, and aspirational performance goals were set by the O&C Committee in February 2021 as industry average, industry top quartile, and 0.00, respectively. For the years 2021 and 2022 in the performance period, industry performance for the performance goals was determined using actual industry results for each respective year. For 2023, industry performance for the performance goals was calculated based on a projected linear trend utilizing industry rates for 2018-2022. In February 2024, the O&C Committee certified the threshold and superior performance goal amounts.

(2)Non-storm SAIDI threshold and superior performance goals were set by the O&C Committee in February 2021 as the Oncor service area 2021-2023 PUCT reliability standard in accordance with 16 Texas Administrative Code § 25.52 and the sum of the average of the annual industry non-storm SAIDI top quartile performance and the annual industry non-storm SAIDI top decile performance for each of 2021-2023, respectively. For the years 2021 and 2022 in the performance period, industry performance for the performance goals was determined using actual industry results for each respective year. For 2023, industry performance for the performance goals was calculated based on a projected linear trend utilizing industry rates for 2018-2022. In February 2024, the O&C Committee certified the superior performance goal amount.

(3)The achievement of threshold, superior and/or aspirational levels, where applicable, results in funding for a specific operational metric of 50%, 150% and 200%, respectively.

(4)Achievement reflects actual performance after taking into account applicable modifiers.

(5)For purposes of the net income growth adder, the 2020 baseline set by the O&C Committee was our 2020 net income adjusted for weather and excludes certain pension and OPEB costs, special project costs and the tax effect of certain adjusted items. The 2023 net income approved by the O&C Committee was adjusted for weather, excludes certain pension and OPEB costs and a one-time write-off resulting from the PUCT’s final order in our comprehensive base rate review, and includes a downward adjustment to reflect the effects of an initiative to accelerate spending in 2022 to offset expense pressure in 2023.

For the awards payable to each Named Executive Officer, see “—Compensation Elements—Long-Term Incentives.”

Other Terms of the Long-Term Incentive Plan

The Long-Term Incentive Plan encourages retention of executive officers and key employees by stipulating performance periods of generally 36 months. Participants must be continuously employed by us through the last day of the performance period in order to receive a long-term incentive award for that performance period. If a participant is employed by us on the last day of the performance period but his or her employment terminates for any reason other than by us for cause prior to the payment of the award for that performance period, the participant will be entitled to receive payment of the award. In the event a participant is terminated by us for cause, the participant will forfeit any unpaid Long-Term Incentive Plan award. Cause has the definition assigned to such term in any employment agreement or change-in-control agreement in effect between the participant and us or any other surviving entity in any change in control transaction or any affiliate thereof which employs the participant at the time of and/or following a change in control (Surviving Entity). If no such agreement exists, cause is defined as (i) the participant engaging in conduct in carrying out his or her employment duties to the Surviving Entity that constitutes (a) a breach of fiduciary duty to the Surviving Entity or its equity holders, (b) gross neglect, or (c) gross misconduct resulting in material and objectively determinable damage to the business of the Surviving Entity, or (ii) the indictment of the participant for, or the participant’s plea of nolo contendere to,

136

a felony or misdemeanor involving moral turpitude. In addition, the Long-Term Incentive Plan provides that a termination shall not constitute a termination for cause for a participant unless the participant has received written notice specifying the alleged misconduct constituting cause, the participant has been given an opportunity to be heard by the board of directors of the Surviving Entity, as applicable, and following such hearing, the applicable board of directors determines in good faith and by at least a two-thirds vote that the termination for cause is appropriate under the circumstances.

The Long-Term Incentive Plan defines a change in control as any one or more of the following events: (i) the acquisition, in one transaction or a series of transactions, of direct or indirect ownership of the equity of Oncor or Sempra that, together with the equity held by such person or group, constitutes more than 50% of the total fair market value, total direct or indirect voting power, or the direct or indirect beneficial ownership of Oncor or Sempra, other than any acquisition of Oncor equity by a wholly-owned subsidiary of Sempra; (ii) the acquisition, during any 12-month period, by any person or group, in one transaction or a series of transactions, of direct or indirect equity of Oncor or Sempra that constitutes 30% or more of the total fair market value, the total direct or indirect voting power, or the direct or indirect beneficial ownership of Oncor or Sempra, other than any acquisition of Oncor equity by a wholly-owned subsidiary of Sempra; (iii) any sale, lease, exchange or other transfer (in one transaction or in a series of transactions) of all, or substantially all, of Oncor’s assets, other than to a wholly-owned subsidiary of Sempra; (iv) the consummation of a transaction for which the PUCT approved a transfer or change of control (operational or otherwise) of Oncor; or (v) a material change to the terms of the Approved Ring Fence (as defined in the LLC Agreement).

The Long-Term Incentive Plan defines good reason to mean any of the following events or actions taken without the express, voluntary consent of the participant: (i) a material reduction in the participant’s base salary or incentive compensation opportunity, other than a broad-based reduction of base salaries or incentive compensation of all similarly situated employees of the Surviving Entity, unless such broad-based reduction only applies to former employees of Oncor; (ii) a material reduction in the aggregate type, level or value of benefits for which the participant is eligible, immediately prior to the change in control, other than a broad-based reduction applicable to all similarly situated employees of the Surviving Entity, unless such reduction only applies to former employees of Oncor; (iii) a material reduction in the participant’s authority, duties or responsibilities, including an adverse change in (a) the participant’s title, reporting level, reporting line or structure, scope of responsibilities, or management authority, or (b) the scope or size of the business, entity, or budget for which the participant had responsibility, in each case as in effect immediately prior to the effective time of the change in control; (iv) the participant’s primary work location is relocated, resulting in an increase in the participant’s work commute in excess of thirty-five miles more than the participant’s work commute immediately prior to the change in control; (v) a material breach by the Surviving Entity of the terms of any employment agreement with the participant; (vi) the failure of Oncor to obtain an agreement by the Surviving Entity, if such entity is not Oncor, to fully assume and perform the provisions of the Long-Term Incentive Plan; or (vii) the participant is asked or required to resign in connection with a change in control and does so resign. In order to constitute a resignation with good reason, however, (x) the participant must provide written notice to the Surviving Entity describing the event or condition constituting good reason within a period of not more than 90 days from the initial occurrence of such event or circumstance, (y) if the applicable event or circumstance is capable of being cured, the Surviving Entity fails or refuses to fully remedy such event or circumstance within a 30-day cure period following the receipt of such notice, and (z) the participant terminates the participant’s employment within two years following the initial existence of one or more of the preceding events or actions.

If a participant’s employment is terminated for reasons other than death, disability, retirement or following a change in control prior to the last day of the performance period, all of such participant’s outstanding and unpaid Long-Term Incentive Plan awards will be cancelled. Upon a termination due to death, disability or retirement, for each outstanding Long-Term Incentive Plan unpaid award, the participant (or his or her beneficiary in the case of death) will be entitled to receive, on the same date as awards are paid for that period to other participants, an award equal to the product of (i) a fraction, the numerator of which is the number of days in the performance period up to and including the date of the separation of service and the denominator of which is the number of days in the entire performance period, and (ii) the Long-Term Incentive Plan award for such performance period based on actual performance of Oncor during the performance period. In the event of a separation from service within two years following a change in control that is initiated by the Surviving Entity for any reason other than for cause, or initiated by the participant for good reason, a participant shall be entitled to receive an award equal to the product of (i) a fraction, the numerator of which is the number of days in the performance period up to and including the date of the separation of service and the denominator of which is the number of days in the entire performance period, and (ii) the Long-Term Incentive Plan award for such performance period based on target performance, which amount will be paid at the same time as paid to current participants, unless the applicable change in control meets certain change in ownership or control provisions of Section 409A(a)(2)(A)(v) of the Code, in which case the amounts will be payable within 60 days following the participant’s separation from service.

137

As the administrator of the Long-Term Incentive Plan, the O&C Committee has the authority to prescribe, amend and rescind rules and regulations relating to the plan, determine the terms and conditions of any awards and make all other determinations deemed necessary or advisable for the administration of the plan. The O&C Committee has broad discretion under the plan and may delegate to one or more officers of the company the authority to grant Long-Term Incentive Plan awards to employees who are not executive officers. The O&C Committee may at any time terminate, alter, amend or suspend the Long-Term Incentive Plan and any awards granted pursuant to it, subject to certain limitations. In the event of a change in control, the O&C Committee may, in its discretion, terminate the plan and cancel all outstanding and unpaid awards, except that in the event of a termination of the plan in connection with a change in control, participants will be entitled to receive the payout as described above. Payments under the Long-Term Incentive Plan are separate from, and would be in addition to, any payments available under the Change in Control Policy or Severance Plan.

(1)Accredited service for each of the plans is determined based on an employee’s age and hire date. Employees hired by Oncor or certain affiliates prior to January 1, 1985 became eligible to participate in the plan the month after their completion of one year of service and attainment of age 25. Employees hired after January 1, 1985 became eligible to participate in the plan on the first day of the month coincident with, or next following, the date on which they complete at least one year of service and attain age 21.

(2)While no payments were made to the Named Executive Officers under the Supplemental Retirement Plan in 2023, distributions were made from Messrs. Nye, Clevenger and Henry’s accounts in December 2023 to pay required Federal Insurance Contributions Act (FICA) taxes with respect to the participant’s respective accrued benefit in the cash balance component of the plan. Those FICA taxes were paid directly to the taxing authorities through payroll withholding and thus are not reported here.

The Oncor Retirement Plan contains both a traditional defined benefit component and a cash balance component. Only employees hired before January 1, 2002 may participate in the traditional defined benefit component. All new employees hired after January 1, 2002 participate in the cash balance component. In addition, the cash balance component covers employees previously participating in the traditional defined benefit component who elected to convert the actuarial equivalent of their accrued traditional defined benefit to the cash balance component during a special one-time election opportunity effective in 2002. The employees that participate in the traditional defined benefit component do not participate in the cash balance component.

Annual retirement benefits under the traditional defined benefit component, which applied during 2023 to Ms. Dennis and Mr. Greer, are computed as follows: for each year of accredited service up to a total of 40 years, 1.3% of the first $7,800, plus 1.5% of the excess over $7,800, of the participant’s average annual earnings (base salary) during his or her three years of highest earnings. Under the cash balance component, which covers Messrs. Nye, Clevenger, and Henry, a hypothetical account is established for participants and credited with monthly contribution credits equal to a percentage of the participant’s compensation (3.5%, 4.5%, 5.5% or 6.5% depending on the participant’s combined age and years of accredited service), plus interest credits based on the average yield of the 30-year Treasury bond for the 12 months ending November 30 of the prior year. Benefits paid under the traditional defined benefit component of the Oncor Retirement Plan are not subject to any reduction for Social Security payments but are limited by provisions of the Code.

138

The Supplemental Retirement Plan provides for the payment of retirement benefits, which would otherwise be limited by the Code or the definition of earnings under the Oncor Retirement Plan, including any retirement compensation required to be paid pursuant to contractual arrangements. Under the Supplemental Retirement Plan, retirement benefits are calculated in accordance with the same formula used under the Oncor Retirement Plan, except that, with respect to calculating the portion of the Supplemental Retirement Plan benefit attributable to service under the traditional defined benefit component of the Oncor Retirement Plan, earnings also include Executive Annual Incentive Plan awards. The amount of earnings attributable to the Executive Annual Incentive Plan awards is reported under the Non-Equity Incentive Plan Compensation column of the Summary Compensation Table.

The table set forth above illustrates the present value on December 31, 2023 of each Named Executive Officer’s Oncor Retirement Plan benefit and benefits payable under the Supplemental Retirement Plan, based on his or her years of service and remuneration through December 31, 2023. Benefits accrued under the Supplemental Retirement Plan after December 31, 2004 are subject to Section 409A of the Code. Accordingly, certain provisions of the Supplemental Retirement Plan have been and may continue to be modified to address the applicable requirements under Section 409A of the Code and related guidance.

The present value of accumulated benefits for the traditional defined benefit component of the Oncor Retirement Plan and the Supplemental Retirement Plan was calculated based on the executive’s annuity payable at the earliest age that unreduced benefits are available under either the Oncor Retirement Plan or Supplemental Retirement Plan (generally age 62). Unmarried executives are assumed to elect a single life annuity. For married executives, it is assumed that 55% will elect a 100% joint and survivor annuity and 45% will elect a single life annuity. Post-retirement mortality was based on the Pri-2012 amounts weighted mortality table projected generationally from 2012 with scale MP-2021. A discount rate of 4.76% was applied and no pre-retirement mortality or turnover was reflected.

The present value of accumulated benefits for the cash balance component of the Oncor Retirement Plan and the Supplemental Retirement Plan was calculated as the value of the executive’s cash balance account projected to age 65 at an assumed growth rate of 3.5% and then discounted back to December 31, 2023, at 4.76%. For married executives, it is assumed that 90% will elect a lump sum, 5% will elect a joint and survivor annuity and 5% will elect a single life annuity. Post-retirement mortality for annuity recipients was based on the Pri-2012 amounts-weighted mortality table projected generationally from 2012 with scale MP-2021. No pre-retirement mortality or turnover assumptions were applied.

The present values of accumulated benefits for the Supplemental Retirement Plan as of December 31, 2023 for Messrs. Nye, Clevenger and Henry were offset by permissible distributions made on December 30, 2023 to taxing authorities to satisfy FICA taxes.

Early retirement benefits under the Oncor Retirement Plan are available to our employees covered in the traditional defined benefit component upon their attainment of age 55 and achievement of 15 years of accredited service. Early retirement results in a retirement benefit payment reduction of 4% for each full year (and 0.333% for each additional full calendar month) between the date the participant retires and the date the participant would reach age 62. As Mr. Greer has achieved age 62 and has over 15 years of service, he is eligible for retirement and his retirement benefits would not be subject to any retirement benefit payment reduction. As Ms. Dennis has achieved age 65, she is eligible for normal retirement and her full retirement benefits. Participants in the cash balance component of the Oncor Retirement Plan can receive their benefit upon retirement or upon separation of service with the company.

Benefits under the Supplemental Retirement Plan are tied to a participant’s coverage under the Oncor Retirement Plan. For participants in the cash balance program of the Oncor Retirement Plan, Supplemental Retirement Plan benefits are generally payable upon the later of (i) a fully vested participant’s separation from service or (ii) the date a fully vested participant would have achieved ten years of accredited service if the participant had remained in continuous employment and not experienced a separation of service. For participants in the traditional defined benefit component of the Oncor Retirement Plan, Supplemental Retirement Plan benefits are generally payable in an annuity on the later of (i) the first day of the second month after a participant’s separation from service or (ii) the earliest date the participant would be eligible to commence benefits under the Oncor Retirement Plan. However, for either traditional defined benefit component or cash balance component participants, Supplemental Retirement Plan benefits are payable as soon as reasonably practical and within 90 days following a separation of service if the lump sum present value of the participant’s total vested benefit amount is less than the dollar amount under the applicable provision of the Code ($22,500 in 2023). Benefits under the Supplemental Retirement Plan are only available to our executive officers and other specified key employees.

Salary Deferral Program

Under the Salary Deferral Program, each employee of Oncor, who is in a designated job level and whose annual salary is equal to or greater than an amount established under the Salary Deferral Program ($152,240 for the program year beginning January 1, 2023) may elect to defer up to 50% of annual base salary and/or up to 85% of any bonus or incentive award. This deferral (including any vested matching contributions, as described below) may be made for a period of seven years, for a period ending with the retirement of such employee, or for a combination thereof, at the election of the employee. Oncor makes a matching award, subject to forfeiture under certain circumstances, equal to 100% of up to the first 8% of base salary deferred under the Salary Deferral Program. Oncor does not match deferred bonus or incentive awards. Matching contributions vest at the earliest of seven years after the deferral date, termination without cause, retirement at the age of 62 or later, death, disability or termination for good reason following a change in control of Oncor. The definitions of “cause,” “change in control,” and “good reason” are substantially consistent with the same definitions in the Change in Control Policy, see “—Potential Payments upon Termination or Change in Control—Change in Control Policy.” Deferrals are credited with earnings or losses based on the performance of investment alternatives under the Salary Deferral Program selected by each participant.

Additionally, Oncor, at the direction of the O&C Committee, can make additional discretionary contributions into a Salary Deferral Program participant’s account. Discretionary contributions made into a Salary Deferral Program participant’s account by Oncor vest as determined by the O&C Committee.

At the end of the applicable account maturity period (seven years or retirement, as elected by the participant or, in the case of company discretionary contributions, as determined by the O&C Committee) the trustee for the Salary Deferral Program distributes the deferrals and the applicable earnings in cash as a lump sum or in annual installments at the participant’s election made at the time of deferral. Oncor is financing the retirement option of the Salary Deferral Program through the purchase of corporate-owned life insurance on lives of some participants. The proceeds from such insurance are expected to allow us to fully recover the cost of the retirement option.

Potential Payments upon Termination or Change in Control

The tables and narrative below provide information for payments to Oncor’s Named Executive Officers (or, as applicable, enhancements to payments or benefits) in the event of termination of employment including due to retirement, voluntary, for cause, death, disability, without cause, or termination after a change in control of Oncor for good reason or without cause. The amounts shown below for our current Named Executive Officers assume that such a termination of employment and/or change in control occurred on December 31, 2023.

In 2023, all of our executive officers were eligible to receive benefits under the terms of the Change in Control Policy and the Severance Plan, as more fully described following the tables below. In addition to the provisions of those plans, the Salary Deferral Program provides that all company-matching awards will become automatically vested in the event of a termination without cause, death, disability, retirement at the age of 62 or later, or termination for good reason following a change in control. The amounts listed in the tables below regarding the Salary Deferral Program only represent the immediate vesting of company matching contributions resulting from termination without cause, death, disability, retirement at the age of 62 or later or a termination for good reason following the occurrence of a change in control. Contributions made to such plan by each Named Executive Officer are disclosed in the Nonqualified Deferred Compensation – 2023 table above. For a more detailed discussion of the Salary Deferral Program, see the Nonqualified Deferred Compensation – 2023 table and the narrative following such table.

Messrs. Nye, Clevenger and Henry participate in the cash balance component of the Oncor Retirement Plan and as a result can elect to receive their Oncor Retirement Plan benefits as a lump sum upon separation of service with the company. In addition, since Messrs. Nye, Clevenger and Henry are fully vested, each would receive their Supplemental Retirement Plan benefits as a lump sum upon such separation of service. Ms. Dennis and Mr. Greer participate in the traditional defined benefit component of the Oncor Retirement Plan, and both are eligible to retire upon termination of employment as a result of meeting the age and service requirements, without their retirement benefits being subject to any payment reduction.

No additional potential payments will be triggered by any termination of employment or change in control, and as a result no amounts are reported in the tables below for such retirement plans. For a more detailed discussion of the terms of the Oncor Retirement Plan and Supplemental Retirement Plan, see the Pension Benefits table above and the narrative following the Pension Benefits table.

All our Named Executive Officers participate in benefit plans for group term life insurance and accidental death and disability. Any benefits received under these policies are paid to the beneficiary by a third-party provider.

Change in Control Policy

Oncor maintains the Change in Control Policy for our senior leadership team, which consists of our executive officers.

The Change in Control Policy provides for the payment of transition benefits to eligible executives if the executive is terminated without cause or resigns for good reason within 24 months following a change in control.

The Change in Control Policy provides that cause has the definition assigned to such term in any employment agreement or change-in-control agreement in effect between the executive and Oncor or any other surviving entity in any change in control transaction or any affiliate thereof which employs the executive at the time of and/or following the change in control (Surviving Company) at the time of termination of employment. If no such agreement exists, cause is defined as (i) the executive engaging in conduct in carrying out his or her employment duties to the Surviving Company that constitutes (a) a breach of fiduciary duty to the Surviving Company or its equity holders, (b) gross neglect, or (c) gross misconduct resulting in material and objectively determinable damage to the business of the Surviving Company, or (ii) the indictment of the executive for, or the executive’s plea of nolo contendere to, a felony or misdemeanor involving moral turpitude. In addition, the Change in Control Policy provides that a termination shall not constitute a termination for cause unless the executive has received written notice specifying the alleged misconduct constituting cause, the executive has been given an opportunity to be heard by the board of directors of the Surviving Company, as applicable, and following such hearing, the applicable board of directors determines in good faith and by at least a two-thirds vote that the termination for cause is appropriate under the circumstances.

The Change in Control Policy defines good reason to mean any of the following events or actions taken without the express, voluntary consent of the executive: (i) a material reduction in the executive’s base salary or incentive compensation opportunity, other than a broad-based reduction of base salaries or incentive compensation of all similarly situated executives of the Surviving Company, unless such broad-based reduction only applies to former executives of Oncor; (ii) a material reduction in the aggregate type, level or value of benefits for which the executive is eligible, immediately prior to the change in control, other than a broad-based reduction applicable to all similarly situated executives of the Surviving Company, unless such reduction only applies to former executives of Oncor; (iii) a material reduction in the executive’s authority, duties or responsibilities, including an adverse change in (a) the executive’s title, reporting level, reporting line or structure, scope of responsibilities, or management authority, or (b) the scope or size of the business, entity, or budget for which the executive had responsibility, in each case as in effect immediately prior to the effective time of the change in control; (iv) the executive’s primary work location is relocated, resulting in an increase in the executive’s work commute in excess of thirty-five miles more than the executive’s work commute immediately prior to the change in control; (v) a material breach by the Surviving Company of the terms of any employment agreement with the executive; (vi) the failure of Oncor to obtain an agreement by the Surviving Company, if such entity is not Oncor, to fully assume and perform the provisions of the Change in Control Policy; or (vii) the executive is asked or required to resign in connection with a change in control and does so resign. In order to constitute a resignation with good reason, however, (x) the executive must provide written notice to the Surviving Company describing the event or condition constituting good reason within a period of not more than 90 days from the initial occurrence of such event or circumstance, (y) if the applicable event or circumstance is capable of being cured, the Surviving Company fails or refuses to fully remedy such event or circumstance within a 30-day cure period following the receipt of such notice, and (z) the executive terminates their employment within two years following the initial existence of one or more of the preceding events or actions.

The Change in Control Policy defines a change in control as any one or more of the following events: (i) the acquisition, in one transaction or a series of transactions, of direct or indirect ownership of the equity of Oncor or Sempra that, together with the equity held by such person or group, constitutes more than 50% of the total fair market value, total direct or indirect voting power, or the direct or indirect beneficial ownership of Oncor or Sempra, other than any acquisition of Oncor’s equity by a wholly-owned subsidiary of Sempra; (ii) the acquisition, during any 12-month period, by any person or group, in one transaction or a series of transactions, of direct or indirect equity of Oncor or Sempra that constitutes 30% or more of the total fair market value, the total direct or indirect voting power, or the direct or indirect beneficial ownership of Oncor or Sempra, other than any acquisition of Oncor equity by a wholly-owned subsidiary of Sempra; (iii) any sale, lease, exchange or other transfer (in one transaction or in a series of transactions) of all, or substantially all, of Oncor’s assets, other than to a wholly-owned subsidiary of Sempra; (iv) the consummation of a transaction for which the PUCT approved a transfer or change of control (operational or otherwise) of Oncor; or (v) a material change to the terms of the Approved Ring Fence (as defined in the LLC Agreement).

147

Our executive officers are eligible to receive the following under the Change in Control Policy:

A one-time lump sum cash severance payment in an amount equal to the greater of (i) a multiple (three times for our chief executive, executive vice presidents, chief financial officer and general counsel (Messrs. Nye, Clevenger, Greer, and Henry), and two times for each other executive officer) of the sum of the executive’s (a) annualized base salary and (b) target annual incentive award for the year of termination or resignation, or (ii) the amount determined under Oncor’s severance plan for non-executive employees (which pays two weeks of an employee’s pay for every year of service up to the 20^th year of service, and three-weeks’ pay for every year of service above 20 years of service);

A cash bonus in an amount equal to a pro rata portion of the executive’s target annual incentive award for the year of termination;

Continued coverage at our or the Surviving Company’s expense, as applicable, under our health care benefit plans for the applicable COBRA period with the executive’s contribution for such plans being at the applicable employee rate for 18 months (unless and until the executive becomes eligible for benefits with another employer) and, if the executive is covered under our healthcare plans through the end of such period, at the end of such continued coverage the executive may continue participation in our health care plans at the applicable COBRA rate for 18 months, in the case of the CEO, or six months, in the case of each other executive, and Oncor or the Surviving Company, as applicable, will reimburse the executive the monthly difference between the applicable employee rate for such coverage and the COBRA rate paid by the executive for such period;

Outplacement assistance at our expense for 18 months, in the case of the CEO, or one year, in the case of the other executive officers, up to a maximum of $40,000 for the CEO, and $25,000 for other executives;

Reimbursement of reasonable legal fees and expenses incurred by an executive in disputing in good faith the benefits under the Change in Control Policy, up to a maximum of $250,000 for each executive;

Any vested, accrued benefits to which the executive is entitled under any of our employee benefits plans; and

If any of the severance benefits described in the Change in Control Policy or any other payments to be received by the executive shall result in an excise tax pursuant to Code Sections 280G or 4999 (excess parachute payments), payable by the executive, then depending on the amounts of any such payments, either (i) a tax gross-up payment will be made to the executive to cover such additional taxes or (ii) a reduction of benefits will be made pursuant to the Change in Control Policy to bring total applicable amounts payable to the executive under the Change in Control Policy and any other payments below the excise tax threshold.

The Change in Control Policy attaches a form of an agreement and release that each executive is required to sign prior to receipt of benefits under the Change in Control Policy, and such form of agreement and release contains a one-year non-solicitation period and provisions regarding confidentiality and non-disparagement. For a period of one year after a termination contemplated by the policy, a participant may not recruit, solicit, induce, encourage or in any way cause any employee, consultant or contractor engaged by Oncor or any affiliate to terminate his or her relationship with Oncor. The Change in Control Policy may be amended by our board of directors or a duly authorized committee of our board of directors at any time, except that any amendments that adversely affects the benefits available to eligible participants cannot be made within 24 months of a change in control or while the company is in the process of negotiating a potential transaction or event which, if consummated, would constitute a change in control.

Severance Plan

We maintain the Severance Plan for our executive team, which consists of our executive officers and certain non-executive vice presidents. The purpose of the Severance Plan is to provide benefits to eligible executives who are not eligible for severance pursuant to another plan or agreement (including an employment agreement) and whose employment is involuntarily terminated for reasons other than:

Cause, which is defined as either (a) the definition in any executive’s applicable employment agreement or change in control agreement or, (b) if there is no such employment or change in control agreement, cause exists: (i) if, in carrying out his or her duties to the company, an executive engages in conduct that constitutes (A) a breach of his or her fiduciary duty to Oncor, its subsidiaries or shareholders (including a breach or attempted breach of the restrictive covenants under the Severance Plan), (B) gross neglect or (C) gross misconduct resulting in material economic harm to Oncor or its subsidiaries, taken as a whole, or (ii) upon the indictment of the executive, or the plea of guilty or nolo contendere by the executive to a felony or a misdemeanor involving moral turpitude;

Participation in our employee long-term disability plan or any successor plan; or

A transaction involving the company or any of its affiliates in which the executive is offered employment with a

148

company involved in, or related to, the transaction.

Our executive officers are eligible to receive the following under the Severance Plan:

For covered executives other than our CEO, a one-time lump sum cash severance payment in an amount equal to the greater of (i) the covered executive’s annualized base salary in effect immediately before the termination, plus the covered executive’s target annual incentive award for the year of the termination, or (ii) the amount determined under Oncor’s severance plan for non-executive employees;

For our CEO, a one-time lump sum cash severance payment in an amount equal to the greater of: (i) (a) a multiple of two times base salary in effect immediately before the termination plus a multiple of two times the target annual incentive award for the year of termination, plus (b) the target annual incentive award for the year of the termination, or (ii) the amount determined under the Oncor’s severance plan for non-executive employees;

Continued coverage at our expense under our health care benefit plans for 18 months, with the executive’s contribution for such plans being at the applicable employee rate (unless and until the executive becomes eligible for coverage for benefits through employment with another employer, at which time the executive’s required contribution shall be the applicable COBRA rate) and, if the executive is covered under our healthcare plans through the end of such period, at the end of such continued coverage the executive may continue participation in our health care plans at the applicable COBRA rate for 18 months, in the case of the CEO, or six months, in the case of each other executive, and Oncor will reimburse the executive the monthly difference between the applicable employee rate for such coverage and the COBRA rate paid by the executive for such period;

Outplacement assistance at the company’s expense for 18 months, in the case of the CEO, or one year, in the case of other executive officers, up to a maximum of $40,000 for the CEO, and $25,000 for other executives; and

Any vested accrued benefits to which the executive is entitled under Oncor’s employee benefits plans.

In order to receive benefits under the plan, a participant must enter into an agreement and release within 45 days of being notified by us of such participant’s eligibility to receive benefits under the plan. The Severance Plan also provides that for a period of one year after a termination contemplated by the plan, a participant may not recruit, solicit, induce or in any way cause any employee, consultant or contractor engaged by Oncor to terminate his or her relationship with Oncor. The Severance Plan also contains provisions relating to confidentiality and non-disparagement.

CEO Pay Ratio for Fiscal Year 2023

Pay Ratio

Our CEO to median employee pay ratio has been calculated in accordance with the rules under the Dodd-Frank Wall Street Reform and Consumer Protection Act and is calculated in a manner consistent with Item 402(u) of Regulation S-K. Mr. Nye’s annual total compensation for 2023, as shown in the Summary Compensation Table above, was $8,040,621.

The median Oncor employee’s annual total compensation in 2023 (other than Mr. Nye) was $181,514, calculated using the same methodology as used in the calculation of the Summary Compensation Table, consisting of base salary, bonus, non-equity incentive plan compensation, change in pension value and non-qualified deferred compensation earnings, and all other compensation (for the median employee, all other compensation consisted of the Oncor thrift plan company match). As a result, the ratio of Mr. Nye’s annual total compensation in 2023 to the median annual total compensation of all Oncor employees (other than Mr. Nye) in 2023 was 44:1, when calculated in a manner consistent with Item 402(u) of Regulation S-K.

Identification of Median Employee

We identified a median employee in 2021, Because there have been no meaningful changes to our employee population or employee compensation arrangements that we reasonably believe would significantly affect the pay ratio disclosure, we have used the same median employee identified in 2021. For purposes of determining the median Oncor employee in 2021, we evaluated all employees, other than Mr. Nye, employed by Oncor as of October 31, 2021 and calculated each such employee’s total cash compensation received through October 31, 2021. Total cash compensation consists of base pay, any incentive compensation, bonuses, and any other cash payments, including, without limitation, any overtime adjustments, overtime meals, taxable reimbursable expenses, holiday pay, and salary deferral program payouts. We did not make any material assumptions, adjustments, or estimates with respect to total cash compensation and we did not annualize the compensation for any full-time employees that were not employed by us for all of 2021. The total compensation of each employee other than Mr. Nye was then ranked lowest to highest to determine the median employee.

Annual Total Compensation

After identifying the median employee based on total cash compensation, as described above, we calculated annual total compensation for such employee using the same methodology we use for our Named Executive Officers as set forth in the Summary Compensation Table above.

Risk Assessment of Compensation Policies and Practices

The O&C Committee reviews the compensation policies and practices applicable to Oncor’s employees (both executive and non-executive) annually during the first quarter of the year in order to determine whether such compensation policies and practices create risks that are reasonably likely to have a material adverse effect on Oncor. In February 2024, the O&C Committee concluded that current compensatory policies and practices do not create risks that are reasonably likely to have a material adverse effect on Oncor. In arriving at this conclusion, the O&C Committee discussed with management the various compensation policies and practices of the company and the compensation payable pursuant to each, and evaluated whether the compensation payable under each plan or policy could result in (i) incenting employees to take risks that could result in a material adverse effect to Oncor, or (ii) payments by the company significant enough to cause a material adverse effect to Oncor.

We believe that the following factors in our employee compensation program limit risks that could be reasonably likely to have a material adverse effect on the company:

Our compensation program is designed to provide a mix of base salary, annual cash incentives and (for eligible employees) long-term cash incentives, which we believe motivates employees to perform at high levels while mitigating any incentive for short-term risk-taking that could be detrimental to our company’s long-term best interests.

We base both annual and long-term incentive compensation largely on the satisfaction of company operational metrics with the goal of motivating performance towards improving the services we provide our customers.

150

Our annual cash incentive programs for both executives and non-executives are subject to maximum payout levels, which help avoid excessive total compensation and reduce the incentive to engage in unnecessarily risky behavior.

We place an emphasis on individual, non-financial performance metrics in determining individual compensation amounts through annual incentive performance modifiers that can adjust awards upward or downward, which provides management (in the case of non-executive employees) and the O&C Committee (in the case of executive employees) the discretion in certain situations to adjust compensation downward if behaviors are not consistent with Oncor’s business values and objectives.

Long-term incentives for eligible employees under the Long-Term Incentive Plan are measured over three years to ensure employees have significant value tied to the long-term performance of the company.

We have internal controls over financial reporting and other financial, operational and compliance policies and practices designed to keep our compensation programs from being susceptible to manipulation by any employee, including our executive officers. These policies and practices include having the O&C Committee acting as the plan administrator for both the Executive Annual Incentive Plan and the Long-Term Incentive Plan.

Director Compensation

The O&C Committee determines compensation for members of our board of directors. Directors who are current officers of Oncor and the member directors designated by each of Sempra (through Oncor Holdings) and Texas Transmission to serve on our board of directors do not receive any fees for their service as a director. See “Item 10. Directors, Executive Officers and Corporate Governance—Director Appointments” for information regarding the designation of member directors. Oncor reimburses all directors for reasonable expenses incurred in connection with their services as directors.

The table below sets forth information regarding the aggregate compensation paid to the members of our board of directors during the fiscal year ended December 31, 2023, other than E. Allen Nye, Jr., whose compensation from Oncor is discussed in “—Compensation Discussion and Analysis” and “—Compensation Tables.” Mr. Nye did not receive any compensation for his service on our board of directors.

In October 2023, the O&C Committee reviewed Meridian’s competitive market analysis of the fees received by our Disinterested Directors, our non-executive Chairman, and our committee chairs using the same peer group used in the October 2023 analysis of executive compensation. See “—Overview—Compensation Benchmarking and Market Data— October 2023 Competitive Market Analysis and Peer Group Comparison” for a description of this peer group. As a result of this review, the O&C Committee increased the fee received by (i) the Disinterested Directors and our non-executive

153

Chairman to $66,250 per quarter, (ii ) the chair of the Governance and Sustainability Committee to $5,000 per quarter, and (iii) the chair of the O&C Committee to $5,000 per quarter to reflect the 50^th percentile of fees paid by companies in the peer group, effective as of the quarter beginning October 1, 2023.

Our LLC Agreement provides that each of Sempra and Texas Transmission has the right to designate two member directors to serve on our board of directors. None of those four member director positions receives compensation from us for service as a director. Mr. Nye, our CEO, does not receive compensation for his service as a director.

Item 12.SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

Equity Compensation Plan Information

As of December 31, 2023, Oncor had no compensation plans in place that authorized the issuance of equity securities of Oncor.

Security Ownership of Equity Interests of Oncor by Certain Beneficial Owners and Management

The following table lists the number of limited liability company membership interests (LLC Units) of Oncor beneficially owned at February 26, 2024 by the holders of more than 5% of our LLC Units (based on information made available to Oncor), our current directors and the Named Executive Officers listed in “Item 11. Executive Compensation—Summary Compensation Table.” See also “Items 1 and 2. Business and Properties—Ring-Fencing Measures” and Note 1 to Financial Statements for a discussion of the various ring-fencing measures that have been taken to enhance the separateness between us and entities with ownership interests in us. As a result of these measures, holders of our LLC Units do not control us, and the ring-fencing measures limit their ability to direct our management, policies and operations.

The amounts and percentages of LLC Units beneficially owned are reported on the basis of SEC regulations governing the determination of beneficial ownership of securities. Under SEC rules, a person is deemed to be a “beneficial owner” of a security if that person has or shares voting power or investment power, which includes the power to dispose of or to direct the disposition of such security. A person is also deemed to be a beneficial owner of any securities of which that person has a right to acquire beneficial ownership within 60 days. Securities that can be so acquired are deemed to be outstanding for purposes of computing such person’s ownership percentage, but not for purposes of computing any other person’s percentage. Under these rules, more than one person may be deemed to be a beneficial owner of the same securities and a person may be deemed to be a beneficial owner of securities as to which such person has no economic interest.

Item 13.CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

Our board of directors has adopted a written policy regarding related person transactions as part of our corporate governance guidelines. Under this policy, a related person transaction shall be consummated or shall continue only if:

1.the Audit Committee of our board of directors approves or ratifies such transaction in accordance with the policy and if the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party;

2.the transaction is approved by the Disinterested Directors; or

3.the transaction involves compensation approved by the O&C Committee of the board of directors.

157

For purposes of this policy, the term “related person” means any related person pursuant to Item 404 of Regulation S-K of the Securities Act, except for transactions with Sempra and its affiliates (other than the Oncor Ring-Fenced Entities), which transactions are subject to restrictions set forth in our LLC Agreement.

A “related person transaction” is a transaction between us and a related person (including any transactions requiring disclosure under Item 404 of Regulation S-K under the Securities Act, if applicable), other than the types of transactions described below, which are deemed to be pre-approved by the Audit Committee:

1.any compensation paid to an executive officer or director if the compensation is reported (or would have been reported, in the case of executive officers that are not named executive officers) under Item 402 of Regulation S-K of the Securities Act, provided that such executive officer or director is not an immediate family member of an executive officer or director and provided that the board of directors or the O&C Committee has approved such compensation;

2.any transaction with another company at which a related person’s only relationship is as a director or beneficial owner of less than 10% of that company’s (other than a partnership) ownership interests;

3.any charitable contribution, grant or endowment by us to a charitable organization, foundation or university at which a related person’s only relationship is as an employee (other than an executive officer) or director;

4.any transaction with a partnership in which a related person’s only relationship is as a limited partner, and the related person is not a general partner and does not hold another position in the partnership, and all related persons have an interest of less than 10% in the partnership;

5.transactions where the related person’s interest arises solely from the ownership of Oncor’s equity securities and all holders of that class of equity securities received the same benefit on a pro rata basis;

6.transactions involving a related party where the rates or charges involved are determined by competitive bids;

7.any transaction with a related party involving the rendering of services as a common or contract carrier, or public utility, as rates or charges fixed in conformity with law or governmental authority;

8.any transaction with a related party involving services as a bank depositary of funds, transfer agent, registrar, trustee under a trust indenture, or similar service;

9.transactions available to all employees or customers generally (unless required to be disclosed under Item 404 of Regulation S-K of the Securities Act, if applicable);

10.transactions involving less than $100,000 when aggregated with all similar transactions;

11.transactions between Oncor and its subsidiaries or between subsidiaries of Oncor;

12.transactions not required to be disclosed under Item 404 of Regulation S-K of the Securities Act; and

13.open market purchases of Oncor or its subsidiaries’ debt or equity securities and interest payments on such debt securities.

Our board of directors has determined that it is appropriate for its Audit Committee to review and approve or ratify related person transactions. In unusual circumstances, we may enter into related person transactions in advance of receiving approval, provided that such related person transactions are reviewed and ratified as soon as reasonably practicable by the Audit Committee of the board of directors. If the Audit Committee determines not to ratify such transactions, we shall make all reasonable efforts to cancel or otherwise terminate such transactions.

The related person transactions policy described above also does not apply to Sempra and its subsidiaries and affiliates (other than the Oncor Ring-Fenced Entities), which are subject to restrictions set forth in our LLC Agreement. Our LLC Agreement requires that we maintain an arm’s-length relationship with the Sempra and its affiliates (other than the Oncor Ring-Fenced Entities) or any other direct or indirect equity holders of Oncor or Oncor Holdings, consistent with the PUCT’s rules applicable to Oncor, and only enter into transactions with Sempra and its affiliates (other than the Oncor Ring-Fenced Entities) that are both (i) on a commercially reasonable basis, and (ii) if such transaction is material, approved

158

by (a) a majority of the members of our board of directors, and (b) prior to a Trigger Event (as defined in our LLC Agreement), the directors appointed by Texas Transmission, at least one of whom must be present and voting in order to approve the transaction.

Related Party Transactions

Operation Agreement With Sharyland

Pursuant to the PUCT order in Docket No. 48929 relating to Oncor’s 2019 acquisition of InfraREIT, Inc., we entered into an operation agreement with Sharyland pursuant to which we provide certain operation services to them at cost with no markup or profit. We provided Sharyland with approximately $659,000 worth of services pursuant to this agreement in 2023. Sempra holds an indirect 50% indirect in Sharyland Holdings, L.P., the parent of Sharyland.

Our LLC Agreement requires that any material transactions with Sempra and its subsidiaries and affiliates (other than the Oncor Ring-Fenced Entities) be approved by a majority of our board of directors and the directors appointed by Texas Transmission present and voting, provided that at least one director appointed by Texas Transmission must be present and voting. The operation agreement was approved by our board of directors, including the directors appointed by Texas Transmission, who were both present and voting.

Tax Sharing Arrangements

We are not a member of another entity’s consolidated tax group, but our owners’ federal income tax returns include their portion of our results. Under the terms of a tax sharing agreement among us, Oncor Holdings, Texas Transmission, and STH, we are generally obligated to make payments to our owners, pro rata in accordance with their respective membership interests, in an aggregate amount that is substantially equal to the amount of federal income taxes that we would have been required to pay if we were filing our own corporate income tax return. STH will file a combined Texas margin tax return which includes our results and our share of Texas margin tax payments, which are accounted for as income taxes and calculated as if we were filing our own return. See discussion in Note 1 to Financial Statements under “Provision in Lieu of Income Taxes.” Under the “in lieu of” tax concept, all in lieu of tax assets and tax liabilities represent amounts that will eventually be settled with our members. In the unlikely event such amounts are not paid under the tax sharing agreement, it is probable that they would be reimbursed to rate payers.

At December 31, 2023, we had $23 million net payables to members under the agreement. It consisted of a current Texas margin tax payable to Sempra totaling $27 million and federal income taxes receivable totaling $4 million ($3 million receivable from Sempra and $1 million receivable from Texas Transmission).

We made net in lieu of income tax payments of $137 million (including $87 million and $22 million in federal income tax-related payments to Sempra and Texas Transmission, respectively, and $28 million in Texas margin tax-related payments to Sempra) in the year ended December 31, 2023.

LLC Agreement of Oncor

In March 2018, in connection with the closing of the Sempra Acquisition, Oncor’s LLC Agreement was amended and restated in its entirety as set forth in the LLC Agreement. The LLC Agreement of Oncor among other things, sets out the members’ respective governance rights in respect of their ownership interests in Oncor. Among other things, the LLC Agreement provides for the management of Oncor by a board of directors consisting of 13 members, including seven Disinterested Directors, two directors designated by Texas Transmission (subject to certain conditions), two directors designated indirectly by Sempra and two directors that are current or former officers of Oncor. Texas Transmission also has the right to designate one non-voting observer to the board of directors, who is entitled to attend all meetings of the board of directors (subject to certain exceptions) and receive copies of all notices and materials provided to the board of directors.

The LLC Agreement prohibits Oncor and its subsidiaries from taking certain material actions outside the ordinary course of business without prior approvals by the members, some or all of the Disinterested Directors and/or the directors designated by one or more of the members. The LLC Agreement also sets forth certain separateness undertakings to ensure Oncor’s legal and financial separateness from Sempra and its direct and indirect subsidiaries (other than the Oncor Ring-

159

Fenced Entities). Additionally, the LLC Agreement contains provisions regulating capital accounts of members, allocations of profits and losses and tax allocation and withholding.

The LLC Agreement describes Oncor’s procedures and limitations on declaring and paying distributions to members. Pursuant to the LLC Agreement, we cannot make any distributions to members (other than contractual tax payments) that would cause us to exceed the PUCT’s authorized debt-to-equity ratio. The distribution restrictions also include the ability of a majority of the Disinterested Directors, or either of the two member directors designated to serve on our board of directors by Texas Transmission, to limit distributions (other than contractual tax payments) to the extent each determines it is necessary to meet expected future requirements of Oncor (including continuing compliance with the PUCT debt-to-equity ratio commitment). In addition, the LLC Agreement provides that if Oncor’s senior secured debt credit rating by any one of S&P, Moody’s or Fitch falls below BBB (Baa2) we must suspend distributions (other than contractual tax payments) until otherwise permitted to do so by the PUCT, and requires that Oncor notify the PUCT if either the credit rating of either Sempra or Oncor falls below its then current level. Distributions also cannot be made to the extent they would violate any applicable laws or regulations. Our LLC Agreement requires that any changes to such procedures and limitations be approved by Oncor Holdings and Texas Transmission and a majority of our board of directors present and voting, which must include (i) a majority of the Disinterested Directors, (ii) both directors appointed to serve on our board of directors by Sempra (through Oncor Holdings), (iii) both directors that are current or former officers of Oncor, and (iv) the directors designated to serve on our board of directors by Texas Transmission who are present and voting, provided that at least one such director must be present and voting in order to approve such matter.

In addition, any annual or multi-year budget with an aggregate amount of capital or operating and maintenance expenditures that are greater than or less than 10% of the capital or operating and maintenance expenditures in the annual budget for the immediately prior fiscal year or multi-year period, as applicable, must be approved by (i) a majority of the Disinterested Directors and (ii) the Texas Transmission director(s) present and voting, provided that at least one Texas Transmission director must be present and voting in order to approve such action. Also, any acquisition of or investment in any third party which involves the purchase of or investment in assets located outside the State of Texas for consideration in an amount greater than $1.5 billion must be approved by (a) a majority of the Disinterested Directors and (b) the Texas Transmission director(s) present and voting, provided that at least one Texas Transmission director must be present and voting in order to approve such action.

Registration Rights Agreement

In November 2008, we entered into a registration rights agreement (Registration Rights Agreement) by and among us, Oncor Holdings, Texas Transmission and STH. The Registration Rights Agreement grants customary registration rights to certain of our members. Subject to certain limitations set forth in the Registration Rights Agreement, these rights include the following: (i) the right of Oncor Holdings and Texas Transmission to demand that we register a specified amount of membership interests in accordance with the Securities Act; (ii) the right of both Oncor Holdings and Texas Transmission to demand registration of a specified amount of membership interests following an initial public offering; and (iii) the right of all members that are parties to the Registration Rights Agreement to have their membership interests registered if we propose to file a registration statement relating to an offering of membership interests (with certain exceptions).

Subject to certain exceptions, whenever we are required to effect the registration of any membership interests pursuant to the Registration Rights Agreement, we have agreed to use our best efforts to cause the applicable registration statement to become effective, and to keep each such registration statement effective until the earlier of (a) at least 180 days (or two years for a shelf registration statement) or (b) the time at which all securities registered under such registration statement have been sold.

Investor Rights Agreement

The investor rights agreement dated as of November 5, 2008, by and among Oncor, Oncor Holdings, Texas Transmission, STH and any other persons that subsequently become a party thereto (Investor Rights Agreement) governs certain rights of certain members of Oncor and STH arising out of their direct or indirect ownership of Oncor membership interests, including, without limitation, transfers of Oncor membership interests and restrictions thereon. Texas Transmission may transfer its Oncor membership interests under a registration statement or pursuant to applicable securities laws. The Investor Rights Agreement also grants Texas Transmission certain “tag-along” rights in relation to certain sales of Oncor membership interests by Oncor Holdings. Subject to certain conditions, these “tag-along” rights allow Texas Transmission to sell a pro-rata portion of its Oncor membership interests in the event of a sale of Oncor

160

membership interests by Oncor Holdings on the same terms as Oncor Holdings would receive for its Oncor membership interests. The agreement further provides that under certain offerings of equity securities occurring before an initial public offering of Oncor, Texas Transmission and Oncor Holdings will receive preemptive rights to purchase their pro-rata share of the equity securities to be sold pursuant to such offerings. The Investor Rights Agreement also provides STH and Sempra with a right of first refusal to purchase any Oncor membership interests to be sold in a permitted sale by Texas Transmission or its permitted transferees.

Additionally, STH, Sempra, certain of Sempra’s subsidiaries and Oncor Holdings have certain “drag-along” rights in relation to offers from third-parties to purchase their directly or indirectly owned membership interests in Oncor, where the resulting sale would constitute a change of control of Oncor. These “drag-along” rights compel Texas Transmission and all other members of Oncor to sell or otherwise transfer their membership interests in Oncor on substantially the same terms as STH, Sempra or Oncor Holdings (as applicable). Pursuant to the Investor Rights Agreement, all members of Oncor that have entered into such agreement must cooperate with Oncor in connection with an initial public offering of Oncor.

Transactions with Affiliates and Portfolio Companies of Certain of our Beneficial Owners

The beneficial owners of Texas Transmission include various entities and funds who make equity investments in various companies (Portfolio Companies) in the ordinary course of their business. We have in the past entered into, and may continue to enter into, transactions with Portfolio Companies or their affiliates in the ordinary course of business on an arm’s-length basis, which may indirectly result in revenues to beneficial owners of Texas Transmission.

Director Independence

Our LLC Agreement provides that seven members of our board of directors must be Disinterested Directors. For a director to be deemed a Disinterested Director, our board of directors must affirmatively determine that (i) such director has not had within the previous ten years, nor currently has, a material relationship with Sempra or its subsidiaries or affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings and (ii) that such director meets the independence standards in Section 303A of the New York Stock Exchange Listed Company Manual in all material respects in relation to Sempra or its subsidiaries and affiliated entities or any entity with a direct or indirect ownership interest in Oncor or Oncor Holdings.

Our board of directors considers which of its members qualify as Disinterested Directors annually, in part by reviewing relevant relationships with organizations with which our directors are affiliated. Our board of directors has determined that each of Messrs. Estrada, Gary, Mack, Saenz and Walker and Mses. Keliher and Rodriguez qualify as both independent directors under the New York Stock Exchange independence standards and as Disinterested Directors under the standards in our LLC Agreement. Prior to their resignations from our board of directors in March 2023, Messrs. Dunning and Hill were also determined to qualify as both independent directors under the New York Stock Exchange independence standards and as Disinterested Directors under the standards in our LLC Agreement.

In connection with its review and determination of independence under the New York Stock Exchange independence standards, our board of directors considered what it viewed as certain non-material relationships and transactions involving our directors, including that Oncor is a dues paying member and has served as a corporate sponsor of the annual meeting of the Dallas Citizens Council, a 501(c)(6) nonprofit organization where Mr. Walker serves as the chief executive officer and Oncor’s chief executive serves on its board of directors.

Mr. Shapard is our Chairman of our board of directors and presides at all meetings of our board of directors. He was appointed non-executive Chairman of our board of directors effective upon the closing of the Sempra Acquisition in March 2018. Mr. Shapard served as our Chief Executive until the closing of the Sempra Acquisition and retired from Oncor effective April 1, 2018.

Our board of directors has designated an Audit Committee, Governance and Sustainability Committee and O&C Committee to exercise certain powers and authorities of the board of the directors. Members of these committees are not required by our LLC Agreement or board of directors to meet any independence standards. Mr. Zucchet, who was designated to serve on our board of directors by Texas Transmission in November 2008, has served on the O&C Committee since May 2010 and the Governance and Sustainability Committee since February 2011. Ms. Newell, who was designated to serve on our board of directors by Texas Transmission in July 2019, has served on the Audit Committee since such date. Mr. Martin, who was designated to serve on our board of directors by Sempra (through Oncor Holdings) in

161

March 2018, has served on the O&C Committee since April 2020. Mr. Mihalik served on our board of directors until January 1, 2024. Mr. Mihalik, who was designated to serve on our board of directors by Sempra (through Oncor Holdings) in March 2020, served on the Audit Committee and the Governance and Sustainability Committee from April 2020 to January 2024. Mr. Bird, who was designed to serve on our board of directors by Sempra (through Oncor Holdings) in January 2024, has served on the Audit Committee and the Governance and Sustainability Committee since January 2024. None of Messrs. Bird, Martin, Mihalik, or Zucchet or Ms. Newell qualifies as independent under the New York Stock Exchange independence standards or as a Disinterested Director for purposes of our LLC Agreement.
