**PART I**

**ITEM 1. BUSINESS**

**OVERVIEW**

Old Dominion Electric Cooperative was incorporated under the laws of the Commonwealth of Virginia in 1948 as a not-for-profit wholesale power supply cooperative. We are organized for the purpose of supplying the power our member distribution cooperatives require to serve their customers on a cost-effective basis. We serve their power requirements pursuant to long-term, all-requirements wholesale power contracts, with limited exceptions. Through our member distribution cooperatives, we served approximately 650,000 retail electric customers (meters), representing a total population of approximately 1.5 million people in 2025.

We supply our member distribution cooperatives' power requirements, consisting of demand requirements and energy requirements, through a portfolio of resources including owned generating facilities, power purchase contracts, and spot market energy purchases. Our generating facilities are fueled by a mix of natural gas, nuclear, coal, and fuel oil. We are a member of a regional transmission organization, PJM, and we participate in its energy, capacity, and transmission services markets to serve our member distribution cooperatives. See "Power Supply Resources" below and "Properties" in Item 2 for a description of these resources.

We are owned entirely by our members, which are the primary purchasers of the power we sell. We have two classes of members. Our Class A members are customer-owned electric distribution cooperatives that supply the power requirements of their retail customers. Our sole Class B member is TEC, a taxable corporation owned by our member distribution cooperatives. Our member distribution cooperatives primarily serve rural, suburban, and recreational areas of the mid-Atlantic region. See "Members—Service Territories and Customers" below.

We are a power supply cooperative. In general, a cooperative is a business organization owned by its members, that are also either the cooperative's wholesale or retail customers. Cooperatives are organized to give their members the opportunity to satisfy their collective needs in a particular area of business more effectively than if the members acted independently. As not-for-profit organizations, cooperatives are intended to provide services to their members on a cost-effective basis, in part by eliminating the need to produce profits or a return on equity in excess of required margins. Margins earned by a cooperative that are not distributed to its members constitute patronage capital, a cooperative's principal source of equity. Patronage capital is held for the account of the members without interest and returned when the board of directors of the cooperative deems it appropriate to do so.

Electric distribution cooperatives form power supply cooperatives to acquire power supply resources, typically through the construction of generating facilities or the acquisition of other power purchase arrangements, at a lower cost than if they were acquiring those resources alone.

We are a not-for-profit wholesale power supply cooperative and currently are exempt from federal income taxation under IRC Section 501(c)(12). We maintain a website at *www.odec.com*. Information contained on our website is not incorporated by reference into and should not be considered to be part of this annual report on Form 10-K.

**MEMBERS**

**Member Distribution Cooperatives**

**General**

Our member distribution cooperatives provide electric services, consisting of power supply, transmission services, and distribution services (including metering and billing services) to residential, commercial, and industrial customers. We have eleven member distribution cooperatives that serve customers in 70 counties in Virginia, Delaware, and Maryland. The member distribution cooperatives' distribution business involves the operation of substations, transformers, and electric lines that deliver power to their customers.

------

Eight of our member distribution cooperatives provide electric services on the Virginia mainland:

BARC Electric Cooperative

Community Electric Cooperative

Mecklenburg Electric Cooperative

Northern Neck Electric Cooperative

Prince George Electric Cooperative

Rappahannock Electric Cooperative

Shenandoah Valley Electric Cooperative

Southside Electric Cooperative

Three of our member distribution cooperatives provide electric services on the Delmarva Peninsula:

A&N Electric Cooperative in Virginia

Choptank Electric Cooperative, Inc. in Maryland

Delaware Electric Cooperative, Inc. in Delaware

The member distribution cooperatives are not our subsidiaries, but rather our owners. We have no interest in their assets, liabilities, equity, revenues, expenses, or margins.

The rates we charge our member distribution cooperatives are regulated by FERC and FERC has granted us authority to charge our member distribution cooperatives utilizing both a formula rate and market-based rates. In accordance with our wholesale power contracts with our member distribution cooperatives, we sell power to them utilizing a formula rate. An exception in the formula rate allows our member distribution cooperatives to elect to utilize market-based rates for new and expanding loads that meet certain criteria.

Revenues from our member distribution cooperatives and the percentage each contributed to total revenues from sales to our member distribution cooperatives in 2025 were as follows:

| &nbsp;&nbsp;&nbsp;&nbsp;Total | $1117.9 | $153.8 | $1271.7 | 100.0% |

---

In 2025, no individual customer of our member distribution cooperatives constituted more than 1.4% of our total revenues from sales to our member distribution cooperatives under the formula rate. In 2025, our member distribution cooperatives elected to utilize market-based rates for five customers. See "Members—Service Territories and Customers" below.

**Service Territories and Customers** 

The territories served by our member distribution cooperatives cover large portions of Virginia, Delaware, and Maryland. These service territories range from the extended suburbs of Washington, D.C. to the North

------

Carolina border and from the Atlantic shores of Virginia, Delaware, and Maryland to the Appalachian Mountains.

Our member distribution cooperatives' service territories encompass primarily rural, suburban, and recreational areas. Our member distribution cooperatives' customers' requirements for capacity and energy generally are seasonal and increase in winter and summer as home heating and cooling needs increase and then decline in the spring and fall as the weather becomes milder. Our member distribution cooperatives also serve major industries which include manufacturing, poultry, telecommunications and data centers, agriculture, forestry and wood products, health care, and recreation.

There is increasing interest by entities with substantially large load requirements, primarily data centers, to locate in the service territories of our member distribution cooperatives, which will likely increase customer concentration. Both the number and size of data centers that are being considered for development and construction in the service territories of our member distribution cooperatives have increased in recent years and we anticipate they will continue to increase substantially over the next several years, thereby materially increasing the aggregate power requirements of our member distribution cooperatives. Our member distribution cooperatives have generally elected to utilize market-based rates to charge data centers for their power requirements. Additionally, there is a provision in the wholesale power contract that permits a member distribution cooperative to purchase power from other suppliers following approval by our board of directors. On February 18, 2025, the VSCC issued an order granting approval for REC to provide power to potential customers with substantially large load requirements through an affiliate of REC. See "Wholesale Power Contracts" and "Regulation of Member Distribution Cooperatives" below, and "Risk Factors" in Item 1A.

Our member distribution cooperatives' sales of energy in 2025 totaled approximately 14,900,000 MWh. These sales were divided by customer class as follows:

![img51645654_0.jpg](img51645654_0.jpg)![img51645654_1.jpg](img51645654_1.jpg)

From 2020 through 2025, our eleven member distribution cooperatives experienced a compound annual growth rate of 1.3% and 5.2% in the number of customers (meters) and energy sales measured in MWh, respectively. The increase in the energy sales measured in MWh is primarily a result of load growth related to data centers. We currently anticipate continued growth in energy sales related to data centers.

Our eleven member distribution cooperatives' average number of customers per mile of energized line is approximately ten customers per mile. The average service density for all electric distribution cooperatives in the United States is approximately eight customers per mile.

The laws of each state grant utilities, including our member distribution cooperatives, the exclusive right to provide transmission and distribution (including metering and billing) services and to be the default providers of power to their customers in service territories certified by their respective state public service commissions. Delaware and Maryland each grant all retail customers the right to choose their power supplier. Virginia currently grants some large retail customers the right to choose their power suppliers and then only in very limited circumstances. See "Regulation of Member Distribution Cooperatives" and "Competition" below, and "Risk Factors" in Item 1A.

------

**Wholesale Power Contracts** 

Our financial relationships with our member distribution cooperatives are based primarily on our contractual arrangements for the supply of power and related transmission and ancillary services. These arrangements are set forth in our wholesale power contracts with our member distribution cooperatives that are effective until January 1, 2079, and beyond this date unless either party gives the other at least three years notice of termination. The wholesale power contracts are all-requirements contracts. Each contract obligates us to sell and deliver to a member distribution cooperative, and obligates that member distribution cooperative to purchase and receive from us, all power that it requires for the operation of its system, with some exceptions, to the extent that we have the power and facilities available to do so.

An exception to the all-requirements obligations of our member distribution cooperatives relates to the ability of our eight mainland Virginia member distribution cooperatives to purchase hydroelectric power allocated to them from SEPA, a federal power marketing administration. Purchases under this exception constituted less than 1% of our member distribution cooperatives' total energy requirements in 2025.

There are two additional exceptions to the all-requirements nature of our wholesale power contracts.

One exception permits each of our member distribution cooperatives, with 180 days prior written notice, to receive up to the greater of 5% of its demand and associated energy or 5 MW of demand and associated energy from its owned generation or other suppliers. The member distribution cooperative may return this load with proper notice. If all of our member distribution cooperatives elected to fully utilize this exception, we estimate the current impact on our load requirements would be a reduction of approximately 183 MW of demand and associated energy. As of December 2025, approximately 16 MW of demand and associated energy had been removed under this provision. We do not anticipate that the current or potential full utilization of this exception or the return of all removed load by our member distribution cooperatives would have a material impact on our results of operations, financial condition, or cash flows.

The second exception permits a member distribution cooperative to purchase power from other suppliers following approval by our board of directors. In this case, if an opportunity is presented to a member distribution cooperative to purchase a component of its all-requirements service from another supplier in excess of the first exception described above, the member distribution cooperative must offer that opportunity to us. If we decline the opportunity or we are otherwise unable to agree on an acceptable contract with the supplier, then the member distribution cooperative may purchase that component of service from the other supplier, subject to our ability to eliminate other purchases and a determination by our board of directors that use of the exception will not materially adversely affect us or our other member distribution cooperatives. Beginning in 2024, opportunities to purchase the power requirements to serve substantially large loads were presented to us, and we declined these opportunities. We continue to evaluate these opportunities as they arise.

Each member distribution cooperative is required to pay us monthly for the power we furnish under its wholesale power contract in accordance with our formula rate or under a market-based rate that a member distribution cooperative may elect in lieu of the formula rate for certain new and expanding loads. The formula rate, which has been filed with and accepted by FERC, is designed to recover our total cost of service and create a firm equity base. See "Regulation—Rate Regulation" below and "Management's Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Results—Formula Rate" in Item 7.

More specifically, the formula rate is intended to meet all of our costs, expenses, and financial obligations associated with our ownership, operation, maintenance, repair, replacement, improvement, modification, retirement, and decommissioning of our generating plants, transmission system, or related facilities; services provided to the member distribution cooperatives; and the acquisition and transmission of power or related services, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•payments of principal and premium, if any, and interest on all our indebtedness (other than payments resulting from the acceleration of the maturity of the indebtedness);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any additional cost or expense, imposed or permitted by any regulatory agency; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•additional amounts necessary to meet the requirement of any rate covenant with respect to coverage of principal and interest on our indebtedness contained in any indenture or contract with holders of our indebtedness.

The rates established under the wholesale power contracts are designed to enable us to comply with financing, regulatory, and governmental requirements that apply to us from time to time.

In accordance with the wholesale power contracts, our board of directors will review our formula rate at least every three years to determine if it reflects and recovers all costs and expenses indicated above, and if it represents the best way to allocate these costs and expenses among our member distribution cooperatives. In making this review, our board of directors will consider if the formula rate results in the proper price signals to our member distribution cooperatives. Due to changes in the energy sector generally and PJM specifically, the review of our formula rate often identifies new or changing bases for the costs we incur. We will not modify our formula rate in any manner that would result in a failure to recover all of our costs and other amounts described above.

**Regulation of Member Distribution Cooperatives** 

Eight of our eleven member distribution cooperatives currently participate in RUS loan or guarantee programs. These member distribution cooperatives have executed loan documents with RUS that we understand contain affirmative and negative covenants, including provisions related to accounting, issuances of securities, rates and charges for the sale of power, construction or acquisition of facilities, and the purchase and sale of power. In addition, we understand financial covenants in these member distribution cooperatives' loan documents require them to design rates to achieve certain interest and debt service coverage ratios. Finally, we understand that for our member distribution cooperatives that do not participate in RUS loan or guarantee programs, their principal loan documentation contains similar covenants.

Our member distribution cooperatives in Virginia are subject to rate regulation by the VSCC for the provision of electric distribution services to their customers, but they have the ability to pass through to their customers changes in their wholesale power costs, including the demand and energy costs we charge our member distribution cooperatives. Our Virginia member distribution cooperatives also may adjust their rates for distribution service without approval by the VSCC provided the adjustment does not result in a cumulative net increase or decrease in excess of 5% in any three-year period. Additionally, the member distribution cooperatives may adjust their rates to collect the fixed costs of owning and operating their distribution systems through a new or modified fixed monthly charge rather than through volumetric charges associated with energy usage, as long as those adjustments are revenue neutral.

Each of our member distribution cooperatives may enter into agreements with customers with substantially large load requirements, subject to compliance with its wholesale power contract with us. See "Wholesale Power Contracts" above. For our Virginia member distribution cooperatives, the terms of those agreements, and any related tariffs made part of the agreements, are subject to VSCC regulation. For Virginia member distribution cooperatives, the VSCC must approve any tariff governing the rates and terms of service between the member distribution cooperative and the substantially large load customer. REC petitioned the VSCC for approval to provide power to 13 potential customers with substantially large load requirements through an affiliate of REC and on February 18, 2025, the VSCC issued an order granting approval of REC's petition. The order states that the approval is for a term of three years from the approval date and is limited to the 13 potential customers with substantially large load requirements identified in the petition. See "Risk Factors" in Item 1A.

The electric distribution rates of our Delaware and Maryland member distribution cooperatives, including wholesale power costs that are a pass-through to their customers, are not regulated by their respective public service commissions.

We, and our member distribution cooperatives, are not subject to any RPS. DEC has voluntarily committed to comply with the Delaware RPS, which it meets through purchases of renewable energy credits, and owned and purchased resources pursuant to the 5% or 5 MW exception in its wholesale power contract with us. See "Wholesale Power Contracts" above.

------

**Competition**

Delaware and Maryland each have laws unbundling the power component (also known as the generation component) of electric service to retail customers, while maintaining regulation of transmission and distribution services. All retail customers in Delaware, including customers of DEC, are permitted to purchase power from a registered supplier only after DEC approves the supplier's ability to do business in its service territory. All retail customers in Maryland, including customers of CEC, are permitted to purchase power from the registered supplier of their choice. As of March 1, 2026, no retail customer of DEC or CEC had switched to an alternative power supplier.

In Virginia, retail choice in the selection of a power supplier is available to customers that consume at least 5 MW of power individually or in the aggregate (with aggregation subject to the approval of the VSCC) and that do not account for more than 1% of the incumbent utility's peak load during the past year. Retail choice is also available to any Virginia customer whose noncoincident peak demand exceeds 90 MW. Additionally, all Virginia retail customers may select an alternative power supplier that provides 100% renewable energy if their incumbent utility, such as one of our member distribution cooperatives, does not offer this same option. Currently, all of our Virginia member distribution cooperatives provide an option to supply a customer with 100% of its requirements from renewable energy. As of March 1, 2026, three retail customers of our Virginia member distribution cooperatives with a total load of approximately 22 MW have switched to an alternative power supplier.

Currently, we do not anticipate that any of these rights to retail choice of our member distribution cooperatives' customers, individually or in the aggregate, will have a material impact on our results of operations, financial condition, or cash flows.

**TEC**

TEC is owned by our member distribution cooperatives and currently is our only Class B member. We have a power sales contract with TEC under which we may sell to TEC power that we do not need to meet the needs of our member distribution cooperatives. TEC then sells this power to third parties under market-based rate authority granted by FERC. In 2025 and 2024, we had no sales to TEC and TEC had no sales to third parties. In 2023, we sold excess power to TEC, and TEC had sales to third parties. Additionally, we have a separate contract under which we may purchase natural gas from TEC; however, we have not purchased natural gas from TEC in 2025, 2024, 2023. TEC does not engage in speculative trading.

**POWER SUPPLY RESOURCES**

**General**

We provide power to our members through a combination of our interests in Wildcat Point, a natural gas-fired combined cycle generation facility; North Anna, a nuclear power station; Clover, a coal-fired generation facility; two natural gas-fired combustion turbine facilities (Louisa and Marsh Run); diesel-fired distributed generation facilities; and physically-delivered forward power purchase contracts and spot market energy purchases. Our energy supply resources for the past three years were as follows:

<sup>(1)</sup> Includes purchases for formula rate and market-based rates sales.

<sup>(2)</sup> Related to our contracts from renewable facilities from which we obtain renewable energy credits. We may sell these renewable energy credits to our member distribution cooperatives and non-members.

In 2025, our generating facilities satisfied approximately 81.0% of our weighted average PJM capacity obligation of approximately 2,932 MW. For a description of our generating facilities, see "Properties" in Item 2. In 2025, we satisfied the remainder of our PJM capacity obligation through the PJM RPM capacity auction process and purchased capacity contracts. See "PJM" below. The energy requirements not met by our owned generating facilities were obtained from multiple suppliers under various long-term and short-term physically-delivered forward power purchase contracts and spot market purchases. See "Power Purchase Contracts" below.

------

Our total available energy and total PJM capacity obligation resources by fuel type and purchase type for 2025 are detailed below:

![img51645654_2.jpg](img51645654_2.jpg)![img51645654_3.jpg](img51645654_3.jpg)

We plan to continue purchasing energy in the future by utilizing a combination of physically-delivered forward power purchase contracts, as well as spot market purchases. As we have done in the past, we expect to adjust our portfolio of power supply resources to reflect our projected power requirements and changes in the market. To assist us in these efforts, we engage ACES, an energy trading and risk management company. Specifically, ACES assists us in negotiating power purchase contracts, evaluating the credit risk of counterparties, modeling our power requirements, bidding and dispatch of the generating facilities that we operate, and executing and settling energy transactions. See "Market Price Risk" in Item 7A.

**Power Supply Planning and CO2 Emission Goals** 

By utilizing various long-term and short-term planning processes and models, we continually evaluate power supply options available to us to meet the needs of our member distribution cooperatives. We have policies that establish targets that define how our projected power needs will be met. One of the ways we manage these targets is the utilization of hedging. We use hedging instruments, including forwards, futures, financial transmission rights, and options, to manage our power and fuel market price risks. These hedging instruments have varying time periods ranging from one month to multiple years in advance. We also evaluate other power supply options including the acquisition, development, or disposition of generating facilities.

As part of our ongoing power supply planning process, on February 3, 2021, we announced a goal to achieve net zero CO2 emissions by 2050 and set an interim goal to reduce our carbon intensity (pounds of CO2 emitted per MWh) by 50% (from 2005 levels) by 2030. As of December 31, 2025, we have reduced our carbon intensity by approximately 41% from 2005 levels. In addition to including carbon emissions related to our owned generating facilities, we impute carbon emissions for our market purchases using the PJM system average emission rate. We do not impute carbon emissions for any renewable power purchases for which we do not retire the renewable energy credits. We will continue to evaluate and monitor industry practices with respect to the calculation of carbon intensity and we may adjust our calculations accordingly.

**PJM** 

**General**

PJM is an RTO that coordinates the transmission of wholesale electricity in all or parts of 13 states in the eastern United States and the District of Columbia. As a federally regulated RTO, PJM must act independently and impartially in managing the regional transmission system and the wholesale electricity market. PJM is primarily responsible for ensuring the reliability of the largest centrally dispatched energy market in North America. PJM coordinates the continuous buying, selling, and delivery of wholesale electricity throughout its members' service territories. PJM system operators continuously conduct dispatch operations and monitor the status of the transmission grid. PJM also oversees a regional planning process for transmission expansion to ensure the continued reliability of the PJM electric system. PJM coordinates and establishes policies for the generation, purchase, and sale of capacity and energy in the control areas of its members.

------

All of our member distribution cooperatives' service territories are located in four transmission zones within PJM. As a member of PJM, we are subject to the operations of PJM, and our generating facilities are under dispatch direction of PJM. We transmit power to our member distribution cooperatives through the transmission facilities subject to operational control of PJM, including a limited amount of transmission facilities we own. See "PJM Transmission" below and "Transmission" in Item 2.

PJM balances its members' power requirements with the power resources available to supply those requirements. Based on this evaluation of supply and demand, PJM schedules and directs the dispatch of available generating facilities throughout its region in a manner intended to meet the demand for energy in the most reliable and cost-effective manner. Thus, PJM directs the dispatch of these facilities even though it does not own them. When the most economical generating facilities cannot be dispatched due to transmission constraints, PJM will direct the dispatch of more expensive generating facilities to meet the required power requirements. PJM members whose power requirements cause the redispatch are obligated to pay the additional costs to dispatch the more expensive generating facilities. These additional costs are commonly referred to as congestion costs. PJM conducts auctions of financial transmission rights for future periods to provide members an opportunity to hedge these congestion costs. PJM also utilizes reliability must run agreements to keep certain power plants operating past their planned retirement dates in order to mitigate reliability concerns. Typically, these facilities are requested to remain operational until transmission upgrades are completed and the costs incurred beyond the planned retirement date to operate these facilities are collected through PJM's transmission rates. For the years ending December 31, 2025, 2024, and 2023, we incurred expenses of $8.4 million, $14.8 million, and $16.2 million, respectively, related to reliability must run costs included in transmission expense.

**PJM Energy Market**

The PJM energy market consists of day-ahead and real-time markets. PJM's day-ahead market is a forward market in which hourly locational marginal prices are calculated for the following day based on the prices at which the owners of generating facilities, including ODEC, offer to run their facilities to meet the requirements of energy customers. PJM's real-time market is a spot market in which current locational marginal prices are calculated at five-minute intervals for generating facilities and hourly for load serving entities.

**PJM Capacity Obligations**

PJM rules require that load serving entities, such as ODEC, meet certain minimum capacity obligations to support reliability of the energy market. These obligations can be met through a combination of owned generation resources and purchases under bilateral agreements and from forward capacity auctions under PJM's capacity rules, known as RPM. PJM compensates us for the capacity of our generating facilities made available for dispatch when called upon. If PJM does not call upon our generating facilities for dispatch, we are still compensated by PJM for capacity. The purpose of PJM's capacity rules is to develop a longer-term pricing program for capacity resources, to provide localized pricing for capacity, and to reduce the resulting investment risk to owners of generating resources, thus encouraging new investment in generating facilities. The pricing is designed to increase significantly when the system has less capacity than the reliability requirement. To address the significant pricing volatility in the capacity market due to decreased reliability margin as a result of ongoing and projected significant load growth, PJM has implemented a price collar that provides a floor and ceiling for capacity auction prices. The value of capacity resources can vary by location and the RPM provides for the recognition of the locational value.

The PJM tariff includes a component referred to as capacity performance, which is intended to improve the reliability of the power grid by increasing the availability of generating units, especially during emergency conditions. Generation owners, such as ODEC, are exposed to significant non-performance charges if their generating units do not operate when dispatched during emergency conditions. Conversely, if generation owners do operate their generating units in excess of their capacity obligation during emergency conditions, they may be eligible for capacity performance bonus payments.

**PJM Transmission**

We have agreements with PJM that provide us with access to transmission facilities under PJM's operational control to deliver energy to our member distribution cooperatives. Transmission costs charged to us under these agreements are the costs associated with moving power from generation facilities to distribution

------

systems, and include costs related to transmission infrastructure and upgrades to that infrastructure. We operate in four transmission zones in PJM, and each zone allocates costs based upon annual peaks or other usage factors within that zone, which impacts the transmission costs we are charged by PJM.

**Power Purchase Agreements**

We purchase significant amounts of power in the market through long-term and short-term physically-delivered forward power purchase contracts. We also purchase power in the spot energy market. This approach to meeting our member distribution cooperatives' energy requirements is not without risks. See "Risk Factors" in Item 1A. To mitigate these risks, we attempt to match our energy purchases with our energy needs to reduce our spot market purchases of energy and sales of excess energy. Additionally, we utilize policies, procedures, and various hedging instruments to manage our power market price risks. These policies and procedures, developed in consultation with ACES, are designed to strike an appropriate balance between minimizing costs and reducing energy cost volatility. See "Market Price Risk" in Item 7A.

**Renewables** 

We have power purchase contracts for approximately 330 MW from wind and solar facilities that are operational. Development of solar projects, including those for which we may contract for in the future, are being impacted by delays and costs related to the regulatory approval and interconnection approval processes, increased financing and labor costs, tariffs, and supply chain issues. We do not have any power purchase contracts for wind or solar facilities that are under development or construction. See "Risk Factors" in Item 1A.

Our contracts for renewables allow us to buy output, including renewable energy credits, from the renewable facilities typically at predetermined prices. We may sell these renewable energy credits to our member distribution cooperatives and non-members. We do not own or operate any of these facilities and are not responsible for their operational costs or performance.

**Fuel Supply**

**Natural Gas** 

We are responsible for procuring the natural gas to be used by all of our units at Wildcat Point, Louisa, and Marsh Run, all of which are located adjacent to natural gas transmission pipelines, and have developed and utilize a natural gas supply strategy. The strategy includes securing transportation contracts and incorporating the ability to use No. 2 distillate fuel oil as a backup fuel for Louisa and Marsh Run. We have identified our primary natural gas suppliers and have negotiated contracts to procure physical natural gas. We also utilize contracts to financially hedge our natural gas costs to mitigate our exposure to natural gas price volatility. We take steps intended to ensure that we have sufficient supplies of natural gas available in the future to support the operation of Wildcat Point and our combustion turbine facilities, but several factors can affect the availability and delivery of natural gas including significant price volatility, prioritization of natural gas distribution, increased reliance on natural gas for power generation in the industry, and reliability issues related to natural gas. See "Risks Factors" in Item 1A and "Market Price Risk" in Item 7A.

**Nuclear**

Virginia Power, an investor-owned utility and the operating agent of North Anna, has the sole authority and responsibility to procure nuclear fuel for the facility. Virginia Power advises us that it primarily uses long-term contracts to support North Anna's nuclear fuel requirements and that worldwide market conditions are continuously evaluated to ensure a range of fuel supply options at reasonable prices, which are dependent upon the market environment. We are not a direct party to any of these procurement contracts and we do not control their terms, conditions, or duration. Virginia Power advises us that current agreements, inventories, and spot market availability are expected to support North Anna's current and planned fuel supply needs for the near term and that additional fuel is purchased as required to attempt to ensure optimal cost and inventory levels.

------

**Coal**

Virginia Power, as operating agent of Clover, has the sole authority and responsibility to procure coal for the facility. We are not a direct party to any of these procurement contracts and we do not control their terms, conditions, or duration. As of December 31, 2025 and December 31, 2024, based on Clover running at full capacity, there was a 29-day and a 70-day supply of coal, respectively. The availability of coal can be impacted by the reduced production of coal, transportation issues, and exports of coal. See "Risk Factors" in Item 1A.

**REGULATION**

**General**

We are subject to regulation by FERC and, to a limited extent, state public service commissions. Some of our operations also are subject to regulation by the Virginia Department of Environmental Quality, the Maryland Department of the Environment, the DOE, the NRC, and other federal, state, and local authorities. Compliance with future laws or regulations may increase our operating and capital costs by requiring, among other things, changes in the design, operation, or maintenance of our generating facilities.

**Rate Regulation**

The rates we charge our member distribution cooperatives are regulated by FERC and FERC has granted us authority to charge our member distribution cooperatives utilizing both a formula rate and market-based rates. The VSCC, the DPSC, and the MPSC do not have jurisdiction over our rates, charges, or services.

Our formula rate is intended to permit us to collect revenues, which, together with revenues from all other sources, including revenues collected under market-based rates, are equal to all of our costs and expenses, plus a targeted amount equal to 20% of our total interest charges, plus additional equity contributions as approved by our board of directors. See "Management's Discussion and Analysis of Financial Condition and Results of Operations—Factors Affecting Results—Formula Rate" in Item 7.

FERC may review our rates upon its own initiative or upon complaint and order a reduction of any rates determined to be unjust, unreasonable, or otherwise unlawful and order a refund for amounts collected during such proceedings in excess of the just, reasonable, and lawful rates.

Our charges to TEC are established under our market-based sales tariff filed with FERC.

**Other Regulation**

In addition to its jurisdiction over rates, FERC also regulates the issuance of securities and assumption of liabilities by us, as well as mergers, consolidations, the acquisition of securities of other utilities, and the disposition of property under FERC jurisdiction. Under FERC regulations, we are prohibited from selling, leasing, or otherwise disposing of the whole of our facilities subject to FERC jurisdiction, or any part of such facilities having a value in excess of $10 million without FERC approval. We are also required to seek FERC approval prior to merging or consolidating our facilities with those of any other entity having a value in excess of $10 million.

The VSCC, the DPSC, and the MPSC oversee the siting of our utility facilities in their respective jurisdictions.

**Environmental** 

We are subject to federal, state, and local laws and regulations, and permits designed to both protect human health and the environment and to regulate the emission, discharge, or release of pollutants into the environment. We believe that we are in material compliance with all current requirements of such environmental laws and regulations and permits. However, as with all electric utilities, the operation of our generating units could be affected by future changes in environmental laws and regulations. We continue to monitor activity related to changes in environmental laws and regulations, including new requirements that could apply to our operations. Capital expenditures and increased operating costs required to comply with any future regulations could be

------

significant. See "Risk Factors" in Item 1A. Our capital expenditures for environmental improvements at our generating facilities were approximately $3.0 million and $0.8 million in 2025 and 2024, respectively.

**Clean Air Act ("CAA")**

Currently, the most significant environmental law affecting our operations is the CAA. The CAA requires, among other things, that owners and operators of fossil fuel-fired generating facilities limit emissions of SO2, particulate matter, mercury, and NOx. Additionally, regulatory programs are in place for new units and for major modifications of existing generating facilities and are being proposed for existing units to limit emissions of CO2 and other GHG. Discussed below are certain standards and regulations under the CAA that impact us.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Cross-State Air Pollution Rule ("CSAPR")

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•This rule requires power plants to reduce SO2 and NOx emissions that contribute to ozone and fine particle pollution in downwind states.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Based upon published allocations/new source set-aside allowances for Virginia and Maryland, we currently anticipate that we will continue to be able to purchase NOx allowances and a limited number of SO2 allowances to maintain compliance under the CSAPR program for Wildcat Point, Clover, Louisa, and Marsh Run.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In 2022, the EPA published a proposed federal implementation plan rule, the "Good Neighbor Plan" rule, that included revised CSAPR ozone season NOx allowances as well as emission rate limits for coal-fired units. The plan was designed to address the CAA "Good Neighbor" requirements related to the 2015 ozone national ambient air quality standards in 23 states. The final rule became effective in 2023; however, there were legal challenges from several states. In 2024, the United States Supreme Court granted emergency applications seeking a stay of the Good Neighbor Plan, pending judicial review. Later that year, the EPA issued a third interim final rule responding to the United States Supreme Court's order by further temporarily amending the Good Neighbor Plan to administratively stay the effectiveness of its requirements for covered facilities in the remaining 11 states (which include Virginia and Maryland). In July 2025, the EPA issued a status update regarding the stay and reconsideration of the Good Neighbor Plan and we currently anticipate a proposed rule will be published during 2026 and a final rule will be effective by the end of 2026. For the 2025 and 2026 ozone seasons, we currently anticipate that there will be sufficient allowances related to the operation of Clover. We continue to follow the legal proceedings and this rulemaking and the potential impact on the operation of Clover.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Acid Rain Program

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•This program requires fossil fuel-fired plants to have SO2 allowances equal to the number of tons of SO2 they emit into the atmosphere annually.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Clover receives an annual allocation of SO2 allowances at no cost based on its baseline operations because it is a facility that was built before the Acid Rain Program commenced.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Wildcat Point, Louisa, and Marsh Run need to obtain allowances under the Acid Rain Program. Because they are primarily gas-fired generating facilities, the number of SO2 allowances these facilities must obtain is typically minimal and can be supplied from any excess SO2 allowances allocated to Clover.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Greenhouse Gas Prevention of Significant Deterioration Permitting

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•These regulations set thresholds for GHG emissions that define when permits are required for new sources, as well as modifications to existing industrial facilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Future renewal of certain permits for Wildcat Point, Clover, Louisa, and Marsh Run may be affected.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•CAA Performance Standards for GHGs for New and Existing Electric Generating Facilities

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In 2023, the EPA proposed performance standards under the CAA for both new (Section 111(b)) and existing (Section 111(d)) generating units for reducing CO2 emissions. The proposed standards included emissions guidelines that would set limits for new gas-fired combustion turbines, existing coal, oil, and gas-fired steam generating units, and certain existing gas-fired combustion turbines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•In 2024, the final rule, which contains requirements to either retrofit existing coal units with carbon controls or retire the asset became effective. Multiple lawsuits were filed against the EPA seeking judicial review of the final regulation and multiple petitions were filed seeking to stay implementation of the rule. Later that year, the United States Court of Appeals for the District of Columbia Circuit and the United States Supreme Court denied requests to stay the rule.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•On June 17, 2025, the EPA published a proposed rule in the Federal Register to repeal a rule that became effective on July 8, 2024, that established performance standards under the CAA for both new (Section 111(b)) and existing (Section 111(d)) generating units for reducing CO2 emissions. The performance standards required owners of new and existing facilities emitting CO2 to either retrofit existing coal units with carbon controls or retire the asset. The EPA's proposed rule contained two alternative proposals. The primary proposal would repeal all existing greenhouse gas emissions standards for fossil-fuel fired electric generating units. The alternative proposal would repeal all carbon capture-related requirements for existing coal and natural gas units and the natural gas co-firing requirements for medium term coal units. Non-carbon capture emissions limits for new natural gas units are proposed to be retained as outlined in the 2024 rule.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•We are continuing to monitor these performance standards as they relate to our generating facilities, particularly Clover. We will be able to determine our compliance strategies after state implementation plans have been developed either related to the 2024 rule or a new rule based upon the proposed repeal. Based on the uncertainties associated with the state implementation plans, we cannot yet determine whether the final rule will have a material adverse effect on our results of operations, financial condition, or cash flows in future periods. There was no material impact on our results of operations, financial condition, or cash flows for the period ending December 31, 2025.

Certain other environmental laws that affect our operations are discussed below.

**Regional Greenhouse Gas Initiative ("RGGI")** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•RGGI, as implemented under the laws of participating northeastern and Mid-Atlantic States, currently including Delaware and Maryland, provides the framework for and administers a cap-and-trade program to regulate and reduce CO2 emissions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Virginia joined RGGI in 2021 pursuant to the 2019 regulation that established an emission limitation program to reduce CO2 from electric power facilities (see "Virginia Clean Economy Act" below). During 2022, the Virginia Department of Environmental Quality took steps to repeal the existing regulation and withdraw from RGGI. In 2023, the repeal became effective which removed Virginia

------

from RGGI at the end of the 2023 reporting year. Legal challenges to the repeal were filed. In 2024, the Circuit Court of Floyd County issued an opinion that found the repeal was unlawful. On March 6, 2025, the Circuit Court of Floyd County ruled to suspend the 2024 judgment, pending appeal. On February 20, 2026, the governor of Virginia signed a budget which includes a requirement for Virginia to rejoin RGGI. On March 5, 2026, the appeal was withdrawn. We are continuing to monitor this process and anticipate that Virginia will rejoin RGGI in 2026 or 2027.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•We are required to purchase RGGI CO2 allowances for each ton of CO2 emitted by Wildcat Point, which is located in Maryland. When Virginia rejoins RGGI, we will also be required to purchase RGGI CO2 allowances for Clover, Louisa, and Marsh Run, which are located in Virginia.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•RGGI finalized its most recent periodic program review and on July 3, 2025, released an updated CO2 model rule. The results of this model rule, which did not include Virginia participation in the modeling scenarios, include significant changes to the annual emissions cap and other program market aspects. From 2027 through 2033, the emissions cap would be reduced by 10.5% annually, and from 2034 through 2037, the emissions cap would be reduced by 3% annually. Setting a regional cap beyond 2037 is expected to be addressed in the next periodic program review currently scheduled to begin in 2028. Additionally, the model rule specifies the amounts and price triggers for the cost containment reserves. We continue to project that there will be an adequate supply of CO2 allowances available for purchase through RGGI auctions or in the secondary market to support our generating facilities. We are continuing to monitor this process, as well as the future inclusion of other adjoining states, to determine any potential impacts on allowance procurement and operational costs.

**Virginia Clean Economy Act**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The act requires that the VAPCB establish rules by 2025 to reduce CO2 emissions from the electric generating sector between 2031 and 2050 and specifies that no emission allowances will be issued in 2050 or future years.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The act requires that substantially all investor-owned utility generating facilities that emit CO2 as a by-product of combustion close by December 31, 2045, including Clover, which we co-own with Virginia Power. However, if the reliability or security of providing electric service to customers is threatened, a petition may be made by Virginia Power to the VSCC requesting relief from the closure requirement.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•We will continue to be engaged in the implementation of the Virginia Clean Economy Act.

**Clean Water Act** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•This act regulates water intake structures, discharges of cooling water, storm water runoff, and other wastewater discharges at generating facilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Our water permits are subject to periodic review and renewal proceedings.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•We do not currently expect a significant impact on our facility operations and will continue to follow revised rulemaking requirements to determine potential future impacts related to our facilities.

**Resource Conservation and Recovery Act**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Rules under this act impose requirements relating to the disposal of CCRs generated by coal combustion at electric generating facilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•These requirements include establishing technical requirements for CCR landfills and surface impoundments, and for monitoring and cleanup of affected soil or groundwater.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•We do not currently expect the operations at Clover to be significantly affected and will continue to monitor the implementation of the CCR rules and the potential impact on the operations at Clover.

**Future Regulation**

New legislative and regulatory proposals are frequently introduced on both the federal and state levels that modify the environmental regulatory programs applicable to our facilities. Changing regulatory requirements can increase our capital and operating costs and adversely affect the ability to operate our existing facilities, as well as restrict the construction of new facilities.

We anticipate that the most material new regulations are likely to arise under the CAA. Pending regulatory proceedings could result in modifications to certain National Ambient Air Quality Standards, the effect of which can ultimately include stricter emissions requirements on new or existing facilities.

There also may be further developments relating to GHG emissions reporting, control, and facility permitting. The EPA has continued to work to further regulate GHGs from fossil-fired generating units, which could result in limitations on the operations of our generating facilities and/or adversely affect our results of operations, financial condition, or cash flows.

We cannot predict the outcome of these or similar events relating to the regulation of our business, any of which could result in a material adverse impact on our results of operations, financial condition, or cash flows. See "Risk Factors" in Item 1A below.

**Human Capital**

Our success depends upon the skills and collective strengths of all of our employees. We focus on the health, safety, and well-being of our employees. We attract and retain our employees by offering competitive compensation and benefits packages, including healthcare, a defined-benefit pension plan, a 401(k) plan, paid time off, and other benefits. We promote educational development of our employees with an education and tuition reimbursement program and encourage employees to participate in related trade associations.

Included in our benefits, is our wellness program. We reimburse our employees for monthly membership fees to a health club of their choice as well as provide regular wellness events at our facilities for our employees.

We promote a safe and healthy work environment at all of our facilities. In addition to safety requirements associated with the operation or maintenance of our facilities, we have programs and procedures designed to improve our safety performance and provide educational information to our employees.

We are committed to being a positive influence in the communities we serve. We encourage our employees to volunteer where they live and work and provide our employees with the opportunity to use working hours to volunteer and support programs that positively impact the quality of life within these communities.

Our workforce is composed of operational staff at our generating facilities and headquarters staff. We are not a party to any collective bargaining agreement. As of March 1, 2026, we had 142 employees, including 52 employees at our generating facilities and 90 employees at our headquarters office. The average tenure of our employees is ten years.

**ITEM 1A. RISK FACTORS**

*The following risk factors and all other information contained in this report should be considered carefully when evaluating ODEC. These risk factors could affect our actual results and cause these results to differ materially from those expressed in any forward-looking statements of ODEC. Other risks and uncertainties, in addition to those that are described below, may also impair our business operations. We consider the risks listed below to be material, but you may view risks differently than we do and we may omit a risk that we consider immaterial but you consider important. An adverse outcome of any of the following risks could materially affect our business or financial condition. These risk factors should be read in conjunction with the other detailed information set forth elsewhere in this report, including "Management's Discussion and Analysis of Financial Condition and Results of Operations", including "Caution Regarding Forward-looking Statements", in Item 7 and "Notes to Consolidated Financial Statements" in Item 8.*

***FINANCIAL, MARKET, AND ECONOMIC RISKS***

***Our financial condition is largely dependent upon our member distribution cooperatives.*** 

Our financial condition is largely dependent upon our member distribution cooperatives satisfying their obligations to us under their wholesale power contracts. In 2025, 73.4% of our revenues from sales to our member distribution cooperatives were received from our four largest members, REC, MEC, SVEC, and DEC. The wholesale power contracts require our member distribution cooperatives to pay us for power furnished to them in accordance with our FERC formula rate or a market-based rate that a member distribution cooperative may elect in lieu of the formula rate for certain new and expanding loads. See "Members—Member Distribution Cooperatives—Wholesale Power Contracts" in Item 1, and "Factors Affecting Results—Formula Rate" in Item 7. Our board of directors, which is composed of representatives of our members, can approve changes in the rates we charge to our member distribution cooperatives without seeking FERC approval, with limited exceptions.

The formula rate is intended to allocate our costs based on how they are incurred. As the circumstances impacting our costs change with the evolving energy sector and PJM market, the potential increases for disagreements with or among our member distribution cooperatives about cost allocation. When changes are necessary, we apply to FERC to modify our formula rate. As a result, one or more of our member distribution cooperatives, or its customers, could challenge the proposed modifications. Such a challenge likely would not cause us to fail to recover all of our costs and other amounts to be collected under the wholesale power contracts, but it could interfere with our ability to work as effectively as an organization as otherwise would be the case if disagreements with or among our member distribution cooperatives did not exist.

Changes occurring in our member distribution cooperatives' service territories and operations and our member distribution cooperatives' response to these changes could erode their financial stability and negatively impact their creditworthiness. This in turn could impact ODEC's financial stability and creditworthiness. We do not oversee our member distribution cooperatives' financial condition and thus we may not be aware of any pending challenges to their financial condition or liquidity.

Our member distribution cooperatives' ability to collect their costs from their members may have an impact on our financial condition. Economic conditions may make it difficult for some customers of our member distribution cooperatives to pay their power bills in a timely manner, which could ultimately affect the financial health of the member distribution cooperatives and the timeliness of payments to us.

***We rely on purchases and delivery of power and fuel from other suppliers that exposes us to market price risk and could increase our operating costs.***

We supply our member distribution cooperatives with all of their power (energy and demand) requirements, with limited exceptions. Our costs to provide this energy and demand are passed through to our member distribution cooperatives under our wholesale power contracts. We obtain the power to serve their requirements from our generating facilities and purchases of power from other power suppliers.

------

Purchasing power helps us mitigate high fixed costs related to the ownership of generating facilities but exposes us to significant market price risk because energy prices can fluctuate substantially. When we enter into long-term power purchase contracts or agree to purchase energy at a date in the future, we utilize our judgment and assumptions in our models. Our judgment and assumptions relate to factors such as future demand for power and market prices of energy and the price of commodities, such as natural gas, used to generate electricity. Our models cannot always accurately predict what will actually occur and our results may vary materially from what our models forecast, which may in turn impact our resulting costs to our members. Our models become less reliable the further into the future that the estimates are made. Although we have developed strategies to attempt to meet our power requirements in an economical manner and we have implemented a hedging strategy intended to limit our exposure to variability in market prices, we still may purchase energy at a price that is higher than other utilities' costs of generating energy or future market prices of energy. For further discussion of our market price risk, see "Market Price Risk" in Item 7A.

We are subject to changes in fuel costs and delivery constraints for our generating facilities, which could increase the cost of generating power. We are also exposed to changes in purchased power costs. Increases in fuel costs and purchased power costs increase the cost to our member distribution cooperatives.

Factors that could influence fuel and purchased power costs include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•weather;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•supply and demand for these commodities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the availability of competitively priced alternative energy sources;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•constraints related to the transportation of fuels;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•price competition among fuels used to produce electricity, including natural gas, coal, and oil;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•availability, dispatch, and efficient operation of our generating facilities and generating facilities owned by others;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•transmission constraints;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the impact of adoption of new technologies in the power industry, such as energy storage technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•federal, state, and local energy and environmental regulation and legislation, including increased regulation of the extraction or burning of natural gas and coal; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•war, acts and threats of terrorism, sabotage, natural disasters, pandemics, and other catastrophic events.

In 2025, we purchased approximately 55.3% of our energy resources. These purchases consisted of a combination of purchases under physically-delivered forward contracts and purchases of energy in the spot market to serve our member distribution cooperatives sales under the formula rate and market-based rates. Purchases of energy from other suppliers will continue in the future and could increase because of growth related to substantially large loads and the risks associated with the operation of our generating facilities, including changes in their dispatch, shutdown, or breakdown or failure of equipment.

***Substantially large loads considered for development and construction in the service territories of our member distribution cooperatives could impact our financial condition and liquidity.*** 

Our member distribution cooperatives serve a variety of major industries, including data centers that have large load requirements. Both the number and size of data centers that are being considered for development and construction in the service territories of our member distribution cooperatives have increased in recent years and we anticipate they will continue to increase substantially over the next several years with the growth of artificial intelligence and other factors, thereby potentially materially increasing the aggregate power requirements of our member distribution cooperatives. Our need to serve the power requirements of these data

------

centers, which could be thousands of MWs over the next decade, has the potential to create several material risks.

The wholesale power contract we have with each of our member distribution cooperatives obligates us to sell and deliver to the member distribution cooperative, and obligates that member distribution cooperative to purchase and receive from us, all power that it requires for the operation of its system, with some exceptions, to the extent that we have the power and facilities available to do so. The rates we charge our member distribution cooperatives are regulated by FERC and FERC has granted us authority to charge our member distribution cooperatives utilizing both a formula rate and market-based rates. In accordance with our wholesale power contracts with our member distribution cooperatives, we sell power to them utilizing a formula rate. An exception in the formula rate allows our member distribution cooperatives to elect to utilize market-based rates for new and expanding loads that meet certain criteria. Under market-based rates, we purchase from PJM the power requirements of data centers (including purchases of energy, capacity, transmission, and ancillary services), and we are financially responsible to PJM for these purchases.

The increased power purchases related to new data centers in our member distribution cooperatives' service territories likely would increase the collateral we are required to post with PJM. These collateral requirements could result in the need to provide additional credit support in the form of cash or standby letters of credit within a short amount of time based on market conditions. Our ability to access additional credit may be limited and our liquidity may be materially impacted in these circumstances. Constraints on our collateral resources could make it more expensive for us to do business with others or risk a potential downgrade of our credit ratings that could increase future borrowing and operating costs.

These adverse consequences also could arise if a data center fails to pay its power bill to our member distribution cooperatives. Any security provided by a data center may not be sufficient to permit our member distribution cooperative to meet its payment obligations under the wholesale power contract. Depending on the amount of the non-payment, our member distribution cooperative may find it difficult to meet its financial obligations to us and others in a timely manner. As a result, we could be subject to credit rating downgrades, increased collateral requirements, and liquidity impairments.

State laws relating to the provision of electric services to large commercial customers may result in other utilities supplying the power requirements of these new data centers, even if our member distribution cooperatives provide distribution services to them. Under Virginia law, our member distribution cooperatives generally are the default providers of power to customers in their respective certificated service territories, but an exception exists for some large retail customers to select their power supplier. This exception may apply to the new data centers being considered in Virginia. Delaware and Maryland grant all retail customers the right to choose their power supplier. In these cases, the retail customer controls the exercise of the right to obtain power supply from a non-incumbent power supplier, with some limitations.

We continue to evaluate the potential impacts of the development, construction, and operation of data centers in our member distribution cooperatives' service territories and will continue to evaluate potential mitigants to these risks. Still, we cannot predict whether the data centers under consideration will ever commence operations, the size and duration of the power requirements of those that do become operational, whether they will seek to be served by a power supplier other than our member distribution cooperatives, and their ability or willingness to pay their financial obligations in a timely manner. For these and other reasons, there can be no assurance that these developments will not have a material adverse effect on our business, results of operations, financial condition, or cash flows.

***Counterparties under energy purchase and natural gas arrangements may fail to perform their obligations to us resulting in default.***

Because we rely substantially on the purchase of energy and natural gas from other suppliers, we are exposed to the risk that counterparties will default in performance of their obligations to us. On an on-going basis, we analyze and monitor the default risks of counterparties and other credit issues related to these purchases, and we may require our counterparties to post collateral with us; however, defaults may still occur. Defaults may take the form of failure to physically deliver the purchased energy or natural gas. If a default occurs, we may be forced to enter into alternative contractual arrangements or purchase energy or natural gas in

------

the forward or spot markets at then-current market prices that may exceed the prices previously agreed upon with the defaulting counterparty. We cannot be assured that the defaulting counterparty will compensate us for any damages resulting from the breach of their obligations.

***The use of hedging instruments could impact our liquidity.***

We use various hedging instruments, including forwards, futures, financial transmission rights, and options, to manage our power market and natural gas price risks. These hedging instruments generally include collateral requirements that require us to deposit funds or post letters of credit with counterparties when their credit exposure to us is in excess of agreed upon credit limits. When commodity prices decrease below the levels where we have hedged future costs, we may be required to use a material portion of our cash or available commitments under our revolving credit facility to cover these collateral requirements. Volatility in the power and natural gas markets impacts our available liquidity and may cause us to change our cash management and liquidity strategies.

***Adverse changes in our credit ratings may require us to provide credit support for some of our obligations and could negatively impact our liquidity and our ability to access capital.***

S&P, Moody's, and Fitch currently rate our outstanding obligations issued under our Indenture at "A+," "A1," and "A+," respectively. Additionally, we have an issuer credit rating of "A+" from S&P, and an implied senior unsecured rating of "A+" from Fitch. If these agencies were to downgrade our ratings, particularly below investment grade, we may be required to deposit funds or post letters of credit related to our power purchase arrangements. To the extent that we would have to provide additional credit support as a result of a downgrade in our ratings, our ability to access additional credit may be limited and our liquidity may be materially impaired. Also, we may be required to pay higher interest rates on borrowings under our revolving credit facility and financings that we undertake in the future, and our potential pool of future investors and funding sources could decrease.

***Poor market performance will affect the asset values in our nuclear decommissioning trust and our defined benefit retirement plans, which may increase our costs.***

We are required to maintain a funded trust to satisfy our future obligation to decommission North Anna. A decline in the market value of those assets due to poor investment performance or other factors may increase our funding requirements for these obligations which would increase our costs.

We participate in the NRECA Retirement Security Plan and the Deferred Compensation Pension Restoration Plan. The cost of these plans is funded by our payments to NRECA. Poor performance of investments in these benefit plans may increase our costs to make up our allocable portion of any underfunding.

***REGULATORY AND LEGISLATIVE RISKS***

***Our generating assets and costs to serve our load may be impacted by regulatory changes and risks in PJM.*** 

PJM, an RTO regulated by FERC, coordinates and establishes policies for the generation, purchase, and sale of capacity and energy in the control areas of its members. We are a member of PJM and we participate in its energy, capacity, and transmission markets to serve our member distribution cooperatives. All of our member distribution cooperatives' service territories are located in PJM. As a member of PJM, we are subject to the operations of PJM, the risks in PJM, and our generating facilities are under dispatch direction of PJM. These risks include potential future market volatility associated with shrinking PJM reserve margins as well as transmission costs and transmission system infrastructure. Material regulatory changes by FERC impacting the operations of PJM, including the design of the wholesale markets or its interpretation of market rules, or changes to pricing rules or rules involving revenue calculations, could adversely impact our costs or operations. See "Power Supply Resources—PJM" in Item 1.

------

***Environmental legislation or regulation may limit our operations or increase our costs or both.***

We are required to comply with numerous federal, state, and local laws and regulations, relating to the protection of the environment. We believe that we have obtained all material environmental approvals currently required to own and operate our existing facilities or that necessary approvals have been applied for and will be issued in a timely manner. We may incur significant additional costs because of compliance with these requirements. Failure to comply with environmental laws and regulations could have a material effect on us, including potential civil or criminal liability and the imposition of fines or expenditures of funds to bring our facilities into compliance. Delay in obtaining, or failure to obtain and maintain in effect, any environmental approvals, or the delay or failure to satisfy any applicable environmental regulatory requirements related to the operation of our existing facilities or the sale of energy from these facilities could result in significant additional cost to us.

Legislation, regulation, and governmental administration priorities can change over time. We cannot predict the cost, effect, or duration of any future environmental legislation or regulation. New environmental laws or regulations, the modification or reinterpretation of existing environmental laws or regulations, or penalties imposed for non-compliance with existing environmental laws or regulations may require us to incur additional expenses and could have a material adverse effect on the cost of power we supply our member distribution cooperatives. Also, the uncertainty related to changes in environmental laws and regulation poses risks related to long-term planning for generation assets and related decisions about future capital expenditures. See "Regulation—Environmental" in Item 1.

***Failure to comply with regulatory reliability standards, and other regulatory requirements could subject us to substantial monetary penalties.***

As a result of the Energy Policy Act of 2005, as amended, owners, operators, and users of bulk electric systems, including ODEC, are subject to mandatory reliability standards enacted by NERC and its regional entities, and enforced by FERC. We must follow these standards, which are in place to require that proper functions are performed to ensure the reliability of the bulk power system. Although the standards are developed by the NERC Standards Committee, which includes representatives of various electric energy sectors, and must be just and reasonable, the standards are legally binding and compliance may require increased capital expenditures and costs to provide electricity to our member distribution cooperatives under our wholesale power contracts. If we are found to be in non-compliance with any mandatory reliability standards, we could be subject to sanctions, including potentially substantial monetary penalties. New, revised, or reinterpreted laws or regulations related to reliability standards or participation in wholesale power markets could also result in substantial monetary penalties if ODEC is found to have violated or failed to comply with applicable standards, laws, and regulations.

***OPERATIONAL RISKS***

***We may have operational deficiencies or catastrophic events related to our generating or transmission facilities.***

The operation of our generating or transmission facilities involves risks, including the breakdown or failure of power generation equipment, transmission lines, piping or other equipment or processes, and performance below expected levels of output or efficiency. The occurrence of any of these events could result in:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•substantial charges assessed by PJM as a result of the expectation that generating facilities would operate if called upon to be dispatched;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significant additional capital expenditures to repair or replace the affected facilities; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the purchase of potentially more costly replacement power on the open market.

------

***We are subject to fuel procurement and delivery risks.***

The operation of our generating facilities involves risks, including the procurement and delivery of an adequate supply of fuel to operate our facilities. Also, there could be substantial price risks due to constraints in the availability or delivery of fuel.

The operation of our natural gas fueled facilities involves risks including the physical availability and delivery of an adequate supply of natural gas to operate our facilities to meet the requirements of PJM. The physical delivery of natural gas has been and may continue to be impacted by reliability issues related to the transportation of natural gas as well as the lack of reliability standards for natural gas suppliers. This can result in constrained delivery or failure to deliver natural gas, which can cause the diminished ability or inability of our generating facilities to operate.

The operation of our coal generating facility involves risks, including the procurement and delivery of an adequate supply of coal to operate the facility and to meet the requirements of PJM. The availability of coal has been and may continue to be impacted by the reduced production of coal due to the closure of mines on the East Coast, transportation issues, and exports of coal to other countries which further reduces the available supply for domestic consumption.

***Construction of new, or expansion of existing, generating and transmission facilities may not result in the anticipated value to our power supply resource portfolio.*** 

Construction projects, such as investments in generating and transmission assets, carry with them the risk that decisions made today can have implications well into the future. Unanticipated market, technology, and regulatory risks regarding particular capital assets can impact their cost to operate and value in the future. Construction carries with it risks relating to timely completion and operational effectiveness. We may not be able to complete construction or expansion projects on time or at all as a result of weather conditions, delays in obtaining or failure to obtain regulatory approvals, delays in obtaining key materials, labor difficulties, other construction delays, difficulties with partners, contractors, or suppliers, or other factors beyond our control. Even if the construction and expansion projects are completed, the total costs of the projects including the impact of tariffs and supply chain issues may be higher than anticipated, the operational performance of the projects may not meet expectations, and we may not be able to timely and effectively integrate these projects into our operations. Any of these or other factors could adversely affect our ability to realize the anticipated benefits from construction and expansion projects.

***We are subject to risks associated with owning an interest in a nuclear generating facility.***

We have an 11.6% undivided ownership interest in North Anna, which provided approximately 10.7% of our energy requirements in 2025. Ownership of an interest in a nuclear generating facility involves risks, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•potential liabilities relating to harmful effects on the environment and human health resulting from the operation of the facility and the storage, handling, and disposal of radioactive materials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•significant capital expenditures relating to maintenance, operation, and repair of the facility, including repairs required by the NRC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•limitations on the amounts and types of insurance commercially available to cover losses that might arise in connection with operation of the facility;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•liability for damages resulting from nuclear incidents at facilities owned by others pursuant to the Price-Anderson Act of 1988, which can result in retroactive nuclear insurance premiums; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•uncertainties regarding the technological and financial aspects of decommissioning a nuclear plant at the end of its licensed life.

------

The NRC has broad authority under federal law to impose licensing and safety-related requirements for the operation of North Anna. If the facility is not in compliance, the NRC may impose fines or shut down the units until compliance is achieved, or both depending upon its assessment of the situation. Revised safety requirements issued by the NRC have, in the past, necessitated substantial capital expenditures at other nuclear generating facilities. North Anna's operating and safety procedures may be subject to additional federal or state regulatory scrutiny as a result of worldwide events related to nuclear facilities. In addition, if a serious nuclear incident at North Anna did occur, it could have a material but presently indeterminable adverse effect on our operations or financial condition. Further, any unexpected shut down at North Anna as a result of regulatory non-compliance or unexpected maintenance will require us to purchase replacement energy.

***Failure to attract and retain a qualified workforce could have an adverse effect on our operations.*** 

We are dependent upon our staff at our generating facilities and headquarters to operate our business. We have an aging workforce and there is increased competition for skilled workforce to replace these individuals. Additionally, the change in the workforce environment expectations by current and potential employees may lead to increased retirements and resignations, as well as a decreased number of potential applicants to fill vacant positions. These challenges could result in loss of institutional knowledge, lower initial productivity, failure to hire adequately qualified replacements, and future availability and cost of contract labor. All of these factors may result in increased costs and adversely affect our operations.

***TECHNOLOGY, CYBERSECURITY RISKS, AND OTHER THREATS*** 

***If we are unable to protect our information systems against service interruption, misappropriation of data, or breaches of security, our operations could be disrupted and our reputation may be damaged.*** 

We operate in a highly regulated industry that requires the continued operation of advanced information technology systems and network infrastructure. We rely on networks, information systems, and other technology, including the internet and third-party hosted servers, to support a variety of business processes and activities. We could be impacted by various events, including deliberate or unintentional cybersecurity incidents (including ransomware). We have been targeted by cyber attacks in the past and likely may be targeted in the future. These attacks may have been carried out, or in the future could be carried out, by individuals, groups, or nation states. Additionally, as technology becomes more prevalent in energy infrastructure, our infrastructure may be subject to increased cyber vulnerability in the future, including through the improper use of or flaws in the application of artificial intelligence and machine learning technologies. Artificial intelligence technologies are complex and rapidly evolving and present challenges and unintended consequences. We may face costs and risks in implementing cyber safeguards in response to new artificial intelligence technologies or complying with any new regulations concerning artificial intelligence. Any of these events could directly or indirectly compromise our information related to the operation or maintenance of our generating or transmission facilities and could adversely affect our ability to effectively operate or manage our facilities. There is also the potential for a significant financial impact on our operations. Additionally, any of these events could impact the ability of Virginia Power, as operator of North Anna and Clover, to operate those facilities.

We also use third parties to electronically process some of our business transactions. Information systems, both ours and those of third-party information processors, are vulnerable to cybersecurity breach and have been attacked in the past. These incidents may be caused by failures during routine operations such as system upgrades or user errors, as well as network or hardware failures, malicious or disruptive software, computer hackers, rogue employees or contractors, cyber attacks by criminal groups or activist organizations, geopolitical events, natural disasters, failures or impairments of telecommunications networks, or other catastrophic events. We cannot be certain that the security measures utilized, including those security measures by third-party vendors, will be adequate against cyber threats and cyber attackers. In addition, cyber incidents could result in unauthorized disclosure of material confidential information, including personal information or sensitive business information.

If our technology systems are breached or otherwise fail, we may be unable to fulfill critical business functions, including the operation of our generating or transmission facilities, our ability to effectively maintain certain internal controls over financial reporting, and loss of assets. Further, our generating facilities rely on an

------

integrated transmission system, a disruption of which could negatively impact our ability to deliver energy to our member distribution cooperatives. A major cyber incident for us or third-party vendors we utilize could result in significant business disruption and expense to repair security breaches or system damage and could lead to litigation, regulatory action, including penalties or fines, and an adverse effect on our reputation. We also may have future compliance obligations related to new mandatory and enforceable NERC reliability standards, and physical security risks to the reliable operation of the bulk power system.

***Technological advancements and other changes impacting power requirements of our member distribution cooperatives' customers may alter energy and demand requirements for power from us.***

Technological advancements are occurring in the electric industry, including advancements related to self-generation and distributed energy technologies. Distributed energy technologies include fuel cells, batteries, microturbines, wind turbines, and solar cells. The increased adoption of distributed energy and energy efficiency technologies, the impact of regional economic conditions and government mandates relating to renewable resources, and changes in our member distribution cooperatives' customer base could change our member distribution cooperatives' demand for power from us and our long-term load expectations.

***War, acts and threats of terrorism, sabotage, natural disasters, extreme weather events, pandemics, and other catastrophic events could adversely affect our operations.***

We cannot predict the impact that any future terrorist attack, sabotage, natural disaster, extreme weather event, or pandemic may have on the energy sector in general, or on our business in particular. Infrastructure facilities, such as electric generating, transmission, and distribution facilities, and RTOs, could be direct targets of, or indirect casualties of, an act of terror or sabotage. The physical compromise of our facilities could adversely affect our ability to effectively operate or manage our facilities and result in increased costs. Additionally, any military strikes or sustained military campaign may affect our business in unpredictable ways, such as changes in financial markets, and disruptions of fuel supplies and energy markets. Instability in financial markets as a result of war, terrorism, sabotage, natural disasters, extreme weather events, pandemics, credit crises, recession, or other factors could have a significant negative effect on the United States economy, affect the availability or delivery of parts or materials that we need to operate our business, or increase the cost of financing and insurance coverage, which could negatively impact our results of operations and financial condition.

**ITEM 1C. CYBERSECURITY**

**Cybersecurity Risk Management**

We operate in a highly regulated industry that requires the continued operation of advanced information technology systems and network infrastructure and we recognize the importance of assessing, identifying, and managing material risks associated with cybersecurity threats. We manage these risks from cybersecurity threats through our enterprise risk management process which is overseen by our board of directors through an enterprise risk management policy. This policy requires a risk management committee, which is chaired by our President and CEO and includes our other executive officers, and which is responsible for managing our risks including cybersecurity. The risk management committee meets on a monthly basis, and can be convened as needed to address any time-sensitive matters arising between scheduled meeting dates.

To protect our information systems from cybersecurity threats, we use various security tools that help prevent, identify, investigate, resolve, remediate, and recover from identified vulnerabilities and security incidents in a timely manner. To address potential material cybersecurity risk in association with the use of third-party providers, we require they meet minimum security requirements. We regularly assess risks from cybersecurity and technology threats and monitor our information systems for potential vulnerabilities.

------

We identify and address cybersecurity threats through a multi-faceted approach including internal IT assessments and procedures, third-party assessments, internal audits, governance, and risk and compliance reviews. Identifying and assessing cybersecurity risk is integrated into our overall risk management processes.

We conduct proactive cybersecurity reviews of our systems and applications, audit applicable processes and applications, perform testing on our security controls, conduct exercises to simulate cybersecurity incidents, conduct employee training, and monitor emerging laws and regulations related to data protection and information security. We evaluate the results and responses to these efforts and implement appropriate changes to improve our security measures.

In accordance with our board policy for incident management and business continuity planning, we have implemented security incident response plans and security incident response teams. These teams include members from multiple functional areas of our organization that identify, investigate, respond, and resolve cybersecurity incidents. Cybersecurity incidents are evaluated and ranked by severity and prioritized for response. We also evaluate the need to include the use of third parties to assist us in the response to a cybersecurity incident. Our Senior Vice President and COO leads the security response teams, and the activities of the security response teams are overseen by our senior management team. Based on the severity of an incident, members of the senior management team determine whether the incident requires immediate escalation to our board of directors.

In the last three fiscal years, we have not experienced any material cybersecurity incidents and the expenses we have incurred from cybersecurity incidents have been immaterial. This includes penalties and settlements, of which there were none. For a description of whether and how risks from identified cybersecurity threats, including as a result of any previous cybersecurity incidents, have materially affected or are reasonably likely to materially affect us, including our business operations and financial condition, see "Risk Factors" in Item 1A.

**Cybersecurity Governance**

Our board of directors oversees our biennial enterprise risk assessment process that we utilize to assess key risks within the company, including security and technology risks and cybersecurity threats. The audit committee of our board of directors oversees our internal control over financial reporting, including with respect to financial reporting-related information systems. The audit committee receives internal audit reports conducted by an independent audit firm on various cybersecurity matters. In addition, our risk management committee reviews and evaluates reports monthly, and as needed, related to cybersecurity activity and incidents.

**ITEM 2. PROPERTIES**

Our principal properties consist of our interest in five electric generating facilities, additional distributed generation facilities across our member distribution cooperatives' service territories, and a limited amount of

<sup>(1)</sup> Net capacity entitlement represents (a) the projected maximum dependable capacity in summer conditions for Wildcat Point, (b) an approximation of our entitlement to the maximum dependable capacity in summer conditions for North Anna and Clover, and (c) a nominal average of summer and winter capacities for Louisa and Marsh Run.

<sup>(2)</sup> We purchased our 11.6% undivided ownership interest in North Anna in December 1983.

<sup>(3)</sup> The units at this facility also operate on No. 2 distillate fuel oil as an alternate fuel source.

**Wildcat Point**

Wildcat Point is a combined-cycle generation facility that consists of two combustion turbines, two heat recovery steam generators, and one steam turbine generator. We are responsible for the operation and maintenance of Wildcat Point and we supply all services, goods, and materials required to operate and maintain the facility, including arranging for the transportation and supply of the natural gas required by the facility.

**North Anna**

Virginia Power is responsible for operating and procuring nuclear fuel for North Anna. See "Power Supply Resources—Fuel Supply—Nuclear" in Item 1. We are entitled to 11.6% of the power generated by North Anna. We are responsible for and must fund 11.6% of all post-acquisition date additions and operating costs associated with North Anna, as well as a pro-rata portion of Virginia Power's administrative and general expenses directly attributable to North Anna. In addition, we separately fund our pro-rata portion of the decommissioning costs of North Anna. ODEC and Virginia Power also bear pro-rata any liability arising from ownership of North Anna, except for liabilities resulting from the gross negligence of the other.

In 2024, the NRC renewed the operating licenses for an additional 20 years for both units at North Anna. The operating licenses now extend through April 1, 2058, and August 21, 2060, for North Anna Unit 1 and Unit 2, respectively.

**Clover**

Virginia Power, the co-owner of Clover, is responsible for operating, and procuring and arranging for the transportation of the fuel required to operate Clover. See "Power Supply Resources—Fuel Supply—Coal" in Item 1. ODEC and Virginia Power are each entitled to half of the power generated by Clover. We are

------

responsible for and must fund half of all additions and operating costs associated with Clover, as well as half of Virginia Power's administrative and general expenses directly attributable to Clover. When Clover was constructed in 1995, it was intended to operate as a baseload generating facility. As changes in the industry have occurred, Clover now serves us principally as a capacity resource with on-site storage of fuel. In this role, Clover is dispatched by PJM when it is economical or required for reliability.

The Virginia Clean Economy Act requires that substantially all investor-owned utility generating facilities that emit CO2 as a by-product of combustion close by December 31, 2045, which would include Clover. However, if the reliability or security of providing electric service to customers is threatened, a petition may be made by Virginia Power to the VSCC requesting relief from the closure requirement.

In 2024, the EPA published a final rule containing performance standards for both new and existing generating units for reducing CO2 emissions. The rule, which is subject to legal challenges, includes emissions guidelines that set limits for new gas-fired combustion turbines, existing coal, oil, and gas-fired steam generating units, and certain existing gas-fired combustion turbines. On June 17, 2025, the EPA published a proposed rule to repeal a rule that became effective on July 8, 2024. The EPA's proposed rule contained two alternative proposals. The EPA requested comments on the 2025 proposed rule by August 7, 2025. For further discussion, see "Regulation—Environmental—Clean Air Act ("CAA")—CAA Performance Standards for GHGs for New and Existing Electric Generating Facilities" in Item 1.

**Combustion Turbine Facilities**

**Louisa**

Louisa consists of five combustion turbines. We are responsible for the operation and maintenance of Louisa and we supply all services, goods, and materials required to operate and maintain the facility, including arranging for the transportation and supply of the natural gas and No. 2 distillate fuel oil required by the facility.

**Marsh Run**

Marsh Run consists of three combustion turbines. We are responsible for the operation and maintenance of Marsh Run and we supply all services, goods, and materials required to operate and maintain the facility, including arranging for the transportation and supply of the natural gas and No. 2 distillate fuel oil required by the facility.

**Distributed Generation Facilities**

We have six distributed generation facilities in our member distribution cooperatives' service territories primarily to enhance our system's reliability. We have 14 MW and 12 MW of distributed generation to serve our member distribution cooperatives on the Virginia mainland and the Virginia portion of the Delmarva Peninsula, respectively.

**Transmission**

We own approximately 110 miles of transmission lines on the Virginia portion of the Delmarva Peninsula. As a transmission owner in PJM, we have relinquished operational control of these transmission facilities to PJM and contracted with third parties to monitor and maintain them.

**Indenture**

The Indenture grants a lien on substantially all of our real property and tangible personal property and some of our intangible personal property in favor of the trustee, with limited exceptions. The obligations outstanding under the Indenture, including all of our long-term indebtedness, are secured equally and ratably by the trust estate under the Indenture.

**AND RESULTS OF OPERATIONS**

**Caution Regarding Forward-looking Statements**

Management's Discussion and Analysis of Financial Condition and Results of Operations contains forward-looking statements regarding matters that could have an impact on our business, financial condition, and future operations. These statements, based on our expectations and estimates, are not guarantees of future performance and are subject to risks, uncertainties, and other factors. These risks, uncertainties, and other factors include, but are not limited to: general business conditions; demand for energy; change in load requirements; federal and state legislative and regulatory actions, and legal and administrative proceedings; changes in and compliance with environmental laws and regulations; general credit and capital market conditions; weather conditions; the cost and availability of commodities used in our industry; disruption due to cybersecurity threats or incidents; and unanticipated changes in operating expenses and capital expenditures. Our actual results may vary materially from those discussed in the forward-looking statements as a result of these and other factors. Any forward-looking statement speaks only as of the date on which the statement is made, and we undertake no obligation to update any forward-looking statement or statements to reflect events or circumstances after the date on which the statement is made even if new information becomes available or other events occur in the future.

**Overview** 

We are a not-for-profit power supply cooperative owned entirely by our eleven Class A member distribution cooperatives and a Class B member, TEC. We supply our member distribution cooperatives' energy and demand requirements through a portfolio of resources including generating facilities, long-term and short-term physically-delivered forward power purchase contracts, and spot market energy purchases. We also supply the transmission services necessary to deliver this power to our member distribution cooperatives.

Our results from operations for the year ended December 31, 2025, as compared to 2024, were primarily impacted by the increase in total revenues from sales to our member distribution cooperatives, increases in purchased power expense, fuel expense, and transmission expense, the decrease in deferred energy expense, and an additional equity contribution.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total revenues from sales to our member distribution cooperatives, which is comprised of sales to our member distribution cooperatives - formula rate and sales to our member distribution cooperatives - market-based rates, increased 18.3%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total revenues from sales to our member distribution cooperatives - formula rate increased 9.0%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Formula rate demand revenues increased 12.2%, substantially due to increases in PJM charges for network transmission services and capacity, and an additional equity contribution of $38.5 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Formula rate energy revenues increased 6.1%, primarily due to the 5.2% increase in energy sales in MWh. The weather was colder in 2025 as compared to 2024 and contributed to the increase in 2025 energy sales in MWh.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Total revenues from sales to our member distribution cooperatives - market-based rates increased 210.8% due to load growth related to increased member distribution cooperative sales to data centers.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Purchased power expense, which includes the cost of purchased energy and capacity, increased 50.0%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Purchased energy costs increased 52.0%, due to the increase in the average cost of purchased energy and the increase in the volume of purchased energy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The average cost of purchased energy increased 36.4%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The volume of purchased energy increased 11.5%, primarily due to the increase in purchased energy in MWh for market-based rates sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Purchased capacity costs increased 33.3%, primarily due to the increase in purchased capacity for market-based rates sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Fuel expense increased 41.4% due to the 21.3% increase in the average cost of fuel and the 16.6% increase in generation from our owned facilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Transmission expense increased 14.5%, primarily due to changes in PJM charges for network transmission services and costs related to the increase in market-based rates sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred energy expense, which represents the difference between energy revenues and energy expenses, decreased $111.9 million, primarily as a result of changes implemented to our total energy rate. In 2025, we under-collected $41.8 million and in 2024, we over-collected $70.1 million. Our deferred energy balance was an over-collection of $59.0 million and $100.8 million, as of December 31, 2025 and 2024, respectively.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Our net margin increased $37.0 million from 2024, primarily as a result of an additional equity contribution of $38.5 million.

**Basis of Presentation**

The accompanying financial statements reflect the consolidated accounts of ODEC and TEC. See "Note 1—Summary of Significant Accounting Policies—General" in Item 8.

**Critical Accounting Policies and Estimates**

The preparation of our financial statements in conformity with generally accepted accounting principles requires that our management make estimates and assumptions that affect the amounts reported in our financial statements. We base these estimates and assumptions on information available as of the date of the financial statements. We consider the following accounting policies to be critical accounting policies due to the estimation involved in each.

**Accounting for Regulated Operations**

We are a rate-regulated entity and, as a result, are subject to the accounting requirements of Accounting for Regulated Operations. In accordance with Accounting for Regulated Operations, certain of our revenues and expenses can be deferred at the discretion of our board of directors, which has budgetary and rate setting authority, if it is probable that these amounts will be collected or returned through our formula rate in future periods. Regulatory assets represent costs that we expect to collect from our member distribution cooperatives based on rates approved by our board of directors in accordance with our formula rate. Regulatory liabilities represent probable future reductions in our revenues associated with amounts that we expect to return to our member distribution cooperatives based on rates approved by our board of directors in accordance with our formula rate. See "Factors Affecting Results—Formula Rate" below. Regulatory assets are generally included in deferred charges and other assets, and regulatory liabilities are generally included in deferred credits and other liabilities. Deferred energy, which can be either a regulatory asset or regulatory liability, is included in current assets or current liabilities, respectively. We recognize regulatory assets and liabilities as expenses or as a reduction in expenses, respectively, concurrent with their collection or return through rates.

**Deferred Energy** 

In accordance with Accounting for Regulated Operations, we use the deferral method of accounting to recognize differences between our energy revenues collected from our member distribution cooperatives and our energy expenses. Deferred energy on our Consolidated Statements of Revenues, Expenses, and Patronage Capital represents the difference between energy revenues, which are based upon energy rates approved by our board of directors, and energy expenses, which are based upon actual energy costs incurred. The deferred energy balance on our Consolidated Balance Sheet represents the net accumulation of any under- or over-collection of

------

energy costs. Under-collected energy costs appear as an asset and will be collected from our member distribution cooperatives in subsequent periods through our formula rate. Conversely, over-collected energy costs appear as a liability and will be returned to our member distribution cooperatives in subsequent periods through our formula rate.

In January and February of 2026, the PJM region experienced extremely cold weather, which increased our member distribution cooperatives' customers' requirements for power as well as increased our purchased power and fuel expenses. As a result, our deferred energy balance changed from an over-collection of energy costs to an under-collection of energy costs. We currently anticipate that our deferred energy balance as of February 28, 2026, will be an under-collection of energy costs of approximately $100 million. To address the under-collection of energy costs, our board of directors approved an increase of 24.1% to our total energy rate, effective May 1, 2026.

**Margin Stabilization**

Margin Stabilization allows us to review our actual demand-related costs of service and demand revenues and adjust revenues from our member distribution cooperatives to meet our financial coverage requirements and accumulate additional equity as approved by our board of directors. Our formula rate allows us to collect and return amounts utilizing Margin Stabilization. We record all adjustments, whether increases or decreases, in the year affected and allocate any adjustments to our member distribution cooperatives based on power sales during that year. We collect these increases from our member distribution cooperatives, or offset decreases against amounts owed by our member distribution cooperatives to us, generally in the succeeding calendar year. We adjust operating revenues and accounts receivable–members or accounts payable–members, as appropriate, to reflect these adjustments. These adjustments are treated as due, owed, incurred, and accrued for the year to which the adjustment relates. See "Factors Affecting Results—Formula Rate" below. The following table details the reduction in revenues utilizing Margin Stabilization for the past three years:

---

| | | | |
|:---|:---|:---|:---|

|  | (in thousands) | (in thousands) | (in thousands) |
| Margin Stabilization adjustment | $14544 | $8349 | $3298 |

**Accounting for Asset Retirement and Environmental Obligations**

Accounting for Asset Retirement and Environmental Obligations requires legal obligations associated with the retirement of long-lived assets to be recognized at fair value when incurred and capitalized as part of the related long-lived asset. In the absence of quoted market prices, we estimate the fair value of our asset retirement obligations using present value techniques, in which estimates of future cash flows associated with retirement activities are discounted using a credit-adjusted risk-free rate. Asset retirement obligations currently reported on our Consolidated Balance Sheet were measured during a period of historically low interest rates. The impact on measurements of new asset retirement obligations using different rates in the future may be significant. Our estimated liability could change significantly if actual costs vary from assumptions or if governmental regulations change significantly.

A significant portion of our asset retirement obligations relates to our share of the future costs to decommission North Anna. As of December 31, 2025 and 2024, our share of North Anna's nuclear decommissioning asset retirement obligation totaled $188.9 million, or 87.1%, of our total asset retirement obligations, and $183.2 million, or 87.3%, of our total asset retirement obligations, respectively. Periodically, a new decommissioning study for North Anna is performed by third-party experts. The third-party experts provide us with periodic site-specific "base year" cost studies in order to estimate the nature, cost, and timing of planned decommissioning activities for North Anna. These cost studies are based on relevant information available at the time they are performed; however, estimates of future cash flows for extended periods are by nature highly uncertain and may vary significantly from actual results. In addition, these estimates are dependent on subjective factors, including the selection of cost escalation rates, which we consider to be a critical assumption. Our current estimate is based on a study that was performed in 2024 and adopted effective December 31, 2024. See "Note 3—Accounting for Asset Retirement and Environmental Obligations" in Item 8.

------

We determine cost escalation rates, which represent projected cost increases over time, due to both general inflation and increases in the cost of specific decommissioning activities. The following table details the weighted average cost escalation rates used by the study:

---

| | |
|:---|:---|
| **Year Study<br>Performed** | **Weighted<br>Average Cost<br>Escalation Rate** |
| 2002 | 3.27% |
| 2005 | 2.42 |
| 2009 | 2.30 |
| 2014 | 2.04 |
| 2019 | 1.85 |
| 2024 | 2.33 |

---

The weighted average cost escalation rate was applied if the cash flows increased as compared to the previous study. The original weighted average cost escalation rate was applied if the cash flows decreased as compared to the previous study. The use of alternative rates would have been material to the liabilities recognized. For example, had we increased the cost escalation rates by 0.5%, the amount recognized as of December 31, 2025, for our asset retirement obligations related to nuclear decommissioning would have been $47.5 million higher.

**Accounting for Derivatives and Hedging** 

We primarily purchase power under both long-term and short-term physically-delivered forward contracts to supply power to our member distribution cooperatives. These forward purchase contracts meet the accounting definition of a derivative; however, a majority of these forward purchase derivative contracts qualify for the normal purchases/normal sales accounting exception under Accounting for Derivatives and Hedging. As a result, these contracts are not recorded at fair value. We record a liability and purchased power expense when the power under the physically-delivered forward contract is delivered. We also purchase natural gas futures generally for five years or less to hedge the price of natural gas for our facilities which utilize natural gas. These derivatives do not qualify for the normal purchases/normal sales accounting exception.

For all derivative contracts that do not qualify for the normal purchases/normal sales accounting exception, we defer all unrealized gains and losses on a net basis as a regulatory liability or regulatory asset, respectively, in accordance with Accounting for Regulated Operations. See "Accounting for Regulated Operations" above. These amounts are subsequently reclassified as purchased power or fuel expense on our Consolidated Statements of Revenues, Expenses, and Patronage Capital as the power or fuel is delivered and/or the contract settles.

Generally, derivatives are reported at fair value on our Consolidated Balance Sheet in other assets and other liabilities. The measurement of fair value is based on actively quoted market prices, if available. Otherwise, we seek indicative price information from external sources, including broker quotes and industry publications. For individual contracts, the use of differing assumptions could have a material effect on the contract's estimated fair value.

**Factors Affecting Results**

**Margins** 

We operate on a not-for-profit basis and, accordingly, seek to generate revenues sufficient to recover our cost of service and produce margins sufficient to establish reasonable reserves, meet financial coverage requirements, and accumulate additional equity approved by our board of directors. Revenues in excess of expenses in any year are designated as net margin attributable to ODEC on our Consolidated Statements of Revenues, Expenses, and Patronage Capital. We designate retained net margins attributable to ODEC on our Consolidated Balance Sheet as patronage capital, which we assign to each of our members on the basis of its class of membership and business with us.

------

**Formula Rate**

Our power sales are comprised of two power products – energy and demand. Energy is the physical electricity delivered through transmission and distribution facilities to customers. We must have sufficient committed energy available to us for delivery to our member distribution cooperatives to meet their maximum energy needs at any time, with limited exceptions. This committed available energy at any time is referred to as demand.

The rates we charge our member distribution cooperatives are regulated by FERC and FERC has granted us authority to charge our member distribution cooperatives utilizing both a formula rate and market-based rates. In accordance with our wholesale power contracts with our member distribution cooperatives, we sell power to them utilizing a formula rate. An exception in the formula rate allows our member distribution cooperatives to elect to utilize market-based rates for new and expanding loads that meet certain criteria.

The rates we charge our member distribution cooperatives under the formula rate are intended to permit collection of revenues which will equal the sum of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all of our costs and expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•20% of our total interest charges (margin requirement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•additional equity contributions approved by our board of directors.

The formula rate identifies the cost components that we can collect through rates, but not the actual amounts to be collected. With limited minor exceptions, we can change our rates periodically to match the costs we have incurred and we expect to incur without seeking FERC approval.

Energy costs, which are primarily variable costs, such as natural gas, nuclear, and coal fuel costs, and the energy costs under our power purchase contracts with third parties, are recovered through two separate rates, the base energy rate and the energy adjustment rate (collectively referred to as the total energy rate). The base energy rate is developed annually to collect energy costs as estimated in our budget including amounts in the deferred energy account from the prior year. As of January 1 of each year, the base energy rate is reset in accordance with our budget and the energy adjustment rate is reset to zero. We can revise the energy adjustment rate during the year if it becomes apparent that the total energy rate is over-collecting or under-collecting our actual and anticipated energy costs. Any revision to the energy adjustment rate requires board approval and that the resulting change to the total energy rate is at least 2%.

Demand costs, which are primarily fixed costs, such as capacity costs under power purchase contracts with third parties, transmission costs, administrative and general expenses, depreciation expense, interest expense, margin requirement, and additional equity contributions approved by our board of directors, are recovered through our demand rates. The formula rate allows us to change the actual demand rates we charge as our demand-related costs change, without FERC approval, with the exception of decommissioning cost, which is a fixed number in the formula rate that requires FERC approval prior to any adjustment. FERC approval is also needed to change account classifications currently in the formula or to add accounts not otherwise included in the current formula. Additionally, depreciation studies are required to be filed with FERC for its approval if they would result in a change in our depreciation rates. We collect our total demand costs through the following three separate rates:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•transmission service rate – designed to collect transmission-related and distribution-related costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•RTO capacity service rate – designed to collect capacity costs in PJM that PJM allocates to ODEC and other PJM members; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•remaining owned capacity service rate – designed to collect all remaining demand costs not billed and/or recovered under the transmission service and RTO capacity service rates.

As stated above, our margin requirement and additional equity contributions approved by our board of directors are recovered through our demand rates. We establish our demand rates to produce a net margin attributable to ODEC equal to 20% of our budgeted total interest charges, plus additional equity contributions approved by our board of directors. The formula rate permits us to adjust revenues from the member distribution

------

cooperatives to equal our actual total demand costs incurred, including a net margin attributable to ODEC equal to 20% of actual interest charges, plus additional equity contributions approved by our board of directors. We make these adjustments utilizing Margin Stabilization. See "Critical Accounting Policies and Estimates—Margin Stabilization" above.

We may revise our budget at any time to the extent that our current budget does not accurately reflect our costs and expenses or estimates of our sales of power. Increases or decreases in our budget automatically amend the energy and/or the demand components of our formula rate, as necessary. If at any time our board of directors determines that the formula does not recover all of our costs and expenses or determines a change in cost allocation methodology among our member distribution cooperatives is appropriate, it may adopt a new formula to meet those costs and expenses, subject to any necessary regulatory review and approval.

**Indenture**

In addition to the requirements of our formula rate, our Indenture obligates us to establish and collect rates for service to our member distribution cooperatives, which are reasonably expected to yield a margins for interest ratio for each fiscal year equal to at least 1.10, subject to any necessary regulatory or judicial approvals. The Indenture requires that these amounts, together with other moneys available to us, provide us moneys sufficient to remain in compliance with our obligations under the Indenture. We calculate the margins for interest ratio by dividing our margins for interest by our interest charges.

Margins for interest under the Indenture equal:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•our net margins;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•plus revenues that are subject to refund at a later date, which were deducted in the determination of net margins;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•plus non-recurring charges that may have been deducted in determining net margins;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•plus total interest charges (calculated as described below);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•plus income tax accruals imposed on income after deduction of total interest for the applicable period.

In calculating margins for interest under the Indenture, we factor in any item of net margin, loss, income, gain, earnings or profits of any of our affiliates or subsidiaries, only if we have received those amounts as a dividend or other distribution from the affiliate or subsidiary, or if we have made a contribution to, or payment under a guarantee or like agreement for an obligation of, the affiliate or subsidiary. Any amounts that we are required to refund in subsequent years do not reduce margins for interest as calculated under the Indenture for the year the refund is paid. The margins for interest ratio was 2.20, 1.27, and 1.27, for the years ended December 31, 2025, 2024, and 2023, respectively.

Interest charges under the Indenture equal our total interest charges (other than capitalized interest) related to (1) all obligations under the Indenture, (2) indebtedness secured by a lien equal or prior to the lien of the Indenture, and (3) obligations secured by liens created or assumed in connection with a tax-exempt financing for the acquisition or construction of property used by us, in each case including amortization of debt discount and expense or premium.

------

**Recognition of Revenue** 

Our operating revenues reflect the actual demand-related costs we incurred plus the energy costs that we collected. Estimated demand-related costs are collected during the period through the demand components of our formula rate. In accordance with Margin Stabilization, these costs, as well as operating revenues, are adjusted at the end of each reporting period to reflect actual demand-related costs incurred during that period. See "Critical Accounting Policies and Estimates—Margin Stabilization" above. Estimated energy costs are collected during the period through the energy components of our formula rate. Operating revenues are not adjusted at the end of each reporting period to reflect actual energy costs incurred during that period. The difference between actual energy costs incurred and energy costs collected during each period is recorded as deferred energy expense, which may be a positive or negative number. See "Critical Accounting Policies and Estimates—Deferred Energy" above.

We bill energy to each of our member and non-member customers based on the total MWh delivered to them each month. We bill demand costs through three separate rates: a transmission service rate, an RTO capacity service rate, and a remaining owned capacity service rate. See "Formula Rate" above. The transmission service rate is billed to each of our member distribution cooperatives based on its contribution to the single zonal coincident peak (the hour of the month the need for energy is highest) for the prior year within each of the PJM transmission zones. The RTO capacity service rate is billed to each of our member distribution cooperatives based on its contribution to the average of the five hourly PJM coincident peaks in the prior year, subject to add-backs for participation in PJM demand response programs. The remaining owned capacity service rate is billed based on the average hourly demand in the prior 12-month period from September 1 to August 31.

**Member Distribution Cooperatives' Requirements for Power**

Changes in the number of customers and those customers' requirements for power significantly affect our member distribution cooperatives' requirements for power. Factors affecting our member distribution cooperatives' requirements for power include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Weather* – Weather affects the demand for energy. Relatively higher or lower temperatures tend to increase the demand for energy to use air conditioning and heating systems, respectively. Mild weather generally reduces the demand for energy because heating and air conditioning systems are operated less. Weather also plays a role in the price of energy through its effects on the market price for fuel, particularly natural gas.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Heating and cooling degree days are measurement tools used to quantify the need to utilize heating or cooling, respectively, for a building. Heating degree days are calculated as the number of degrees below 60 degrees in a single day. Cooling degree days are calculated as the number of degrees above 65 degrees in a single day. In a single calendar day, it is possible to have multiple heating degree and cooling degree days.

The heating and cooling degree days for the past three years were as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Commercial growth* – The amount, size, and usage of electronics and machinery and the expansion of operations among our member distribution cooperatives' existing and new commercial and industrial customers, including data centers, impact the requirements for power. There is increasing interest by entities with substantially large load requirements to locate in the service territories of our member distribution cooperatives. See "Risk Factors—Financial, Market, and Economic Risks" in Item 1A for a description of factors associated with potential service to entities with substantially large load requirements that could impact our financial condition and liquidity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Economy* – General economic conditions have an impact on the rate of growth of our member distribution cooperatives' requirements for power.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Residential growth* – Residential growth in our member distribution cooperatives' service territories and increases in consumption levels increase the requirements for power.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•*Behind-the-meter (distributed generation) resources* – Growth in the number of consumers who serve all or a portion of their electricity requirements from resources behind-the-meter, such as solar panels or local micro-grids, reduces the requirements for power.

For additional discussion of our member distribution cooperatives' customers, see "Members—Member Distribution Cooperatives—Service Territories and Customers" in Item 1.

**Power Supply Resources**

In an attempt to provide stable power costs to our member distribution cooperatives, we utilize a combination of our owned generating resources and purchases from the market. We also regularly evaluate options for future power sources, including additional owned generation and power purchase contracts.

Market forces influence the structure and price of new power supply contracts into which we enter. When we enter into long-term power purchase contracts or agree to purchase energy at a date in the future, we rely on models based on our judgment and assumptions of factors such as future demand for power and market prices of energy and the price of commodities, such as natural gas, used to generate electricity. Our actual results may vary from what our models predict, which may in turn impact our resulting costs to our members. Additionally, our models become less reliable the further into the future that the estimates are made. See "Risk Factors" in Item 1A.

In 2025, our generating facilities satisfied approximately 81.0% of our PJM capacity obligation and 44.7% of our energy requirements. We obtained the remainder of our PJM capacity obligation through the PJM RPM capacity auction process and purchased capacity contracts. Although we expect that capacity costs in PJM will increase, we expect that the corresponding generation capacity credits we receive from PJM will also increase. The energy requirements not met by our owned generating facilities were obtained from multiple suppliers under various long-term and short-term physically-delivered forward power purchase contracts and spot market purchases. See "Power Supply Resources" in Item 1 and "Properties" in Item 2.

**PJM** 

PJM is an RTO that serves all of Delaware and Maryland, and most of Virginia, as well as other areas outside our member distribution cooperatives' service territories. We are a member of PJM and are therefore subject to the operations of PJM. PJM coordinates and establishes policies for the generation, purchase, and sale of capacity and energy in the control areas of its members, including all of the service territories of our member distribution cooperatives. As a result, our generating facilities are under dispatch direction of PJM.

PJM balances its members' power requirements with the power resources available to supply those requirements. Based on this evaluation of supply and demand, PJM schedules and directs the dispatch of available generating facilities throughout its region in a manner intended to meet the demand for energy in the most reliable and cost-effective manner. Thus, PJM directs the dispatch of these facilities even though it does not own them. When the most economical generating facility cannot be dispatched due to transmission constraints, PJM will direct the dispatch of more expensive generating facilities to meet power requirements. For these reasons, actions by PJM may materially affect our operating results. PJM compensates us for the capacity of our generating facilities made available without regard to whether our generating facilities are dispatched. See "Power Supply Resources—PJM" in Item 1.

We transmit power to our member distribution cooperatives through the transmission facilities subject to PJM operational control, including a limited amount of transmission facilities we own. We have agreements with PJM which provide us with access to transmission facilities under PJM's control as necessary to deliver energy to our member distribution cooperatives. See "Transmission" in Item 2.

Transmission owners within PJM have made significant investments in their transmission systems. Because transmission rates are established to recover the cost of investment plus a return on the investment, PJM's rates for network transmission services have increased significantly in recent years. Our transmission costs are impacted each year by billing determinants, which are based on our usage during either the peak hour

------

of the year or the peak hour of each month, depending upon the transmission zone. See "Results of Operations—Operating Expenses" below.

**Generating Facilities**

Our operating expenses, and consequently our rates to our member distribution cooperatives, are significantly affected by the operations of our generating facilities, which are under dispatch direction of PJM. See "PJM" above.

**Operational Availability**

The operational availability of our owned generating resources for the past three years was as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | **Year Ended December 31,** | **Year Ended December 31,** | **Year Ended December 31,** |
|  | **2025** | **2024** | **2023** |
| Wildcat Point | 87.6% | 88.8% | 88.6% |
| North Anna | 89.2 | 94.8 | 94.3 |
| Clover | 60.8 | 67.9 | 75.5 |
| Louisa | 95.7 | 93.3 | 93.6 |
| Marsh Run | 93.5 | 90.1 | 90.8 |

---

The operational availability is impacted by planned maintenance outages as well as unplanned outages.

**Capacity Factor**

The output of Wildcat Point, North Anna, and Clover for the past three years as a percentage of maximum dependable capacity rating of each facility, was as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | **Year Ended December 31,** | **Year Ended December 31,** | **Year Ended December 31,** |
|  | **2025** | **2024** | **2023** |
| Wildcat Point | 38.9% | 34.6% | 51.8% |
| North Anna | 90.5 | 96.4 | 95.5 |
| Clover | 22.1 | 12.3 | 3.3 |

---

Each unit at North Anna is scheduled for refueling approximately every 18 months. While only one unit is refueled at a time, this refueling schedule typically results in both units being off-line for refueling during the same calendar year once every three years. During 2025, both units at North Anna were off-line for refueling. During 2024 and 2023, one unit at North Anna was off-line for refueling.

There has been an increase in the capacity factor for Clover due to Virginia's withdrawal from RGGI at the end of 2023. See "Regulation—Environmental—Regional Greenhouse Gas Initiative ("RGGI")" in Item 1. Clover continues to be a reliable component of our power supply resources portfolio.

**Changing Environmental Legislation and Regulation**

We are subject to extensive federal and state regulation regarding environmental matters. This regulation is becoming increasingly stringent through amendments to federal and state statutes and the development of regulations authorized by existing law. Future federal and state legislation and regulations present the potential for even greater obligations to limit the impact on the environment from the operation of our generating and transmission facilities. The impact of these developments can have a material adverse effect on our results of operations, financial condition, or cash flows, depending on the final terms of new regulations and how those rules are implemented. See "Regulation—Environmental" in Item 1 and "Risk Factors" in Item 1A.

**Taxable Status**

We are a not-for-profit wholesale power supply cooperative and currently are exempt from federal income taxation under IRC Section 501(c)(12). In order to maintain our tax-exempt status, we must receive at least 85%

------

of our income from our members on an annual basis. We maintained our tax-exempt status as of December 31, 2025.

**Zero-emission Nuclear Power Production Tax Credit**

The Inflation Reduction Act of 2022 provides for the zero-emission nuclear power production tax credit for electricity produced at a qualified nuclear power facility, including North Anna, and sold to an unrelated third party beginning in 2024. In November 2025, we filed a claim for $24.3 million in zero-emission nuclear power production tax credit and elected direct pay reimbursement for tax year 2024 based on existing guidance. Additionally, we recorded $19.2 million in zero-emission nuclear power production tax credit for tax year 2025 for which we expect to seek direct pay reimbursement to be reflected on our 2025 tax return. We have established a receivable as well as a regulatory liability for $43.5 million. The ultimate zero-emission nuclear power production tax credit realized by us may vary significantly based on future IRS guidance.

**Results of Operations** 

**Operating Revenues** 

Our operating revenues are derived from sales of power and renewable energy credits to our member distribution cooperatives and non-members. ODEC sells excess purchased and generated energy not needed to meet the actual needs of our member distribution cooperatives to PJM, TEC, or other counterparties. Our financial statements represent the consolidated financial statements of ODEC and TEC and through the consolidation process, all intercompany balances and transactions have been eliminated and TEC's sales are reflected as non-member revenues. Our operating revenues and energy sales in MWh by type of purchaser for the past three years were as follows:

<sup>(2)</sup> Includes renewable energy credit sales of $24.2 million, $24.9 million, and $24.3 million for the years ended December 31, 2025, 2024, and 2023, respectively.

**Member Distribution Cooperatives** 

The rates we charge our member distribution cooperatives are regulated by FERC and FERC has granted us authority to charge our member distribution cooperatives utilizing both a formula rate and market-based rates. In accordance with our wholesale power contracts with our member distribution cooperatives, we sell

------

power to them utilizing a formula rate. An exception in the formula rate allows our member distribution cooperatives to elect to utilize market-based rates for new and expanding loads that meet certain criteria.

**Formula Rate**

Our operating revenues from sales to member distribution cooperatives - formula rate for the past three years were as follows:

---

In 2025, total formula rate revenues increased $92.0 million, or 9.0%, as compared to 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Formula rate demand revenues increased $59.8 million, or 12.2%, substantially due to increases in PJM charges for network transmission services and capacity, and an additional equity contribution of $38.5 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Formula rate energy revenues increased $32.5 million, or 6.1%, primarily due to the 5.2% increase in energy sales in MWh. The weather was colder in 2025 as compared to 2024 and contributed to the increase in 2025 energy sales in MWh.

The following table summarizes the changes to our total energy rate since 2023, which were implemented to address the differences in our realized as well as projected energy costs. See "Factors Affecting Results—Formula Rate" above.

| &nbsp;&nbsp;&nbsp;&nbsp;Total Operating Expenses | $1233842 | $1067001 | $1017294 |

---

Our operating expenses are comprised of the costs that we incur to generate and purchase power to meet the needs of our member distribution cooperatives, and the costs associated with any sales of power to non-members. Our energy costs generally are variable and include fuel expense, the energy portion of our purchased power expense, and the variable portion of operations and maintenance expense. Our demand costs generally are fixed and include the capacity portion of our purchased power expense, transmission expense, the fixed portion of operations and maintenance expense, administrative and general expense, and depreciation and amortization expense. Additionally, all non-operating expenses and income items, including investment income, and interest charges, net, are components of our demand costs. See "Factors Affecting Results—Formula Rate" above.

In 2025, total operating expenses increased $166.8 million, or 15.6%, as compared to 2024, primarily as a result of increases in purchased power expense, fuel expense, and transmission expense, partially offset by the decrease in deferred energy expense and the amortization of regulatory asset/(liability), net.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Purchased power expense, which includes the cost of purchased energy and capacity, increased $181.0 million, or 50.0%.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Purchased energy costs increased $167.9 million, or 52.0%, due to the increase in the average cost of purchased energy and the increase in the volume of purchased energy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The average cost of purchased energy increased 36.4%.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•The volume of purchased energy increased 11.5%, primarily due to the increase in purchased energy in MWh for market-based rates sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;▪Purchased capacity costs increased $13.1 million, or 33.3%, substantially due to the increase in purchased capacity for market-based rates sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Fuel expense increased $79.9 million, or 41.4%, due to the 21.3% increase in the average cost of fuel and the 16.6% increase in generation from our owned facilities.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Transmission expense increased $28.2 million, or 14.5%, primarily due to changes in PJM charges for network transmission services and costs related to the increase in market-based rates sales.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred energy expense, which represents the difference between energy revenues and energy expenses, decreased $111.9 million, primarily as a result of changes implemented to our total energy rate. In 2025, we under-collected $41.8 million and in 2024 we over-collected $70.1 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Amortization of regulatory asset/(liability), net expense decreased $25.2 million due to changes in the nuclear decommissioning trust. See "Other Items—Investment (Expense)/Income, Net" below.

**Other Items**

**Investment (Expense)/Income, Net**

In 2025, investment (expense)/income, net changed $26.1 million as compared to 2024, primarily due to a change in investments in the nuclear decommissioning trust during 2025, which resulted in a realized loss. As a rate-regulated entity, we account for certain revenues and expenses in accordance with Accounting for Regulated Operations, which allows certain of our revenues and expenses to be deferred. We deferred this realized loss through amortization of regulatory asset/(liability), net expense, resulting in no impact on net margin attributable to ODEC on the consolidated statements of revenues, expenses, and patronage capital. See "Critical Accounting Policies and Estimates—Accounting for Regulated Operations" above.

**Interest Charges, Net**

The primary factors affecting our interest charges, net are issuances of indebtedness, scheduled payments of principal on our indebtedness, interest charges related to our revolving credit facility (including fees), and interest paid to our member distribution cooperatives on prepayment balances, which is included in other interest. The major components of interest charges, net for the past three years were as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | **Year Ended December 31,** | **Year Ended December 31,** | **Year Ended December 31,** |
|  | **2025** | **2024** | **2023** |
|  | (in thousands) | (in thousands) | (in thousands) |
| Interest on long-term debt | $(44235) | $(46260) | $(49064) |
| Interest on revolving credit facility | (3213) | (7046) | (7061) |
| Other interest | (3728) | (5552) | (6640) |
| &nbsp;&nbsp;&nbsp;&nbsp;Total interest charges | (51176) | (58858) | (62765) |
| Allowance for borrowed funds used during construction | 3295 | 2332 | 1433 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Interest charges, net | $(47881) | $(56526) | $(61332) |

---

**Net Margin Attributable to ODEC**

In 2025, net margin attributable to ODEC, which is a function of our total interest charges plus any additional equity contributions approved by our board of directors, increased $37.0 million as compared to 2024. Our board of directors approved an additional equity contribution of $38.5 million that was collected in 2025. Additional equity contributions are collected through rates charged to our member distribution cooperatives and are used to fund future capital expenditures. Our board of directors also approved an additional equity contribution of $27.5 million to be collected in 2026. See "Factors Affecting Results—Formula Rate" above.

**Discussion of Results of Operations Comparing 2024 to 2023**

For discussion of our financial results comparing 2024 to 2023, see "Results of Operations" in Item 7 of our 2024 Annual Report on Form 10-K, filed with the Securities and Exchange Commission on March 18, 2025.

**Financial Condition**

The principal changes in our financial condition from December 31, 2024 to December 31, 2025, were caused by the increases in long-term debt, regulatory liabilities, nuclear decommissioning trust, accounts receivable, and accounts receivable–members, and decreases in revolving credit facility, accounts payable–members, and deferred energy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Long-term debt increased $199.8 million due to the $250 million issuance of long-term debt on December 16, 2025, partially offset by scheduled long-term debt payments.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Regulatory liabilities increased $88.6 million primarily due to the $55.0 million change in the unrealized gain on the nuclear decommissioning trust and the establishment of a $43.5 million regulatory liability for the zero-emission nuclear power production tax credit, partially offset by the deferral of the realized loss on a change in investments in the nuclear decommissioning trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Nuclear decommissioning trust increased $47.9 million primarily due to the unrealized gain on securities owned in the nuclear decommissioning trust, partially offset by the $13.8 million realized loss on a change in investments in the nuclear decommissioning trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Accounts receivable increased $45.5 million primarily due to the $43.5 million receivable established related to the zero-emission nuclear power production tax credit. A regulatory liability was established to record the offset to the receivable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Accounts receivable–members increased $37.9 million due to the $24.8 million increase in wholesale power invoices for December 2025 as compared to December 2024, and the $13.1 million increase in member distribution cooperatives extended payment balances, in accordance with the member power bill payment plan. See "Note 1—Summary of Significant Accounting Policies—Member Power Bill Payment Plan" in Item 8.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Revolving credit facility decreased $65.0 million due to the payment of borrowings under this facility with funds from the $250 million debt issuance in 2025. See "Liquidity and Capital Resources—Financings" below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Accounts payable–members decreased $52.0 million primarily due the $57.6 million decrease in member distribution cooperatives prepayments, slightly offset by the $6.2 million increase in amounts owed to our member distribution cooperatives utilizing Margin Stabilization. See "Note 1—Summary of Significant Accounting Policies—Member Power Bill Payment Plan" in Item 8.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred energy decreased $41.8 million as a result of the under-collection of our energy costs in 2025. Our deferred energy balance was an over-collection of $59.0 million and $100.8 million as of December 31, 2025 and 2024, respectively.

**Equity Ratio** 

Our equity ratio was 32.8% and 33.6%, as of December 31, 2025 and 2024, respectively. Equity ratio equals patronage capital divided by the sum of our long-term debt, borrowings outstanding under our revolving credit facility, long-term debt due within one year, and patronage capital.

**Liquidity and Capital Resources**

**Sources**

Cash generated by our operations, periodic borrowings under our revolving credit facility, and occasional issuances of long-term indebtedness provide our sources of liquidity and capital.

------

**Operations**

In 2025 and 2024, our operating activities provided cash flows of $85.3 million and $257.4 million, respectively. In 2023, our operating activities used cash flows of $16.3 million.

**Revolving Credit Facility**

We maintain a revolving credit facility to cover our short-term and medium-term funding needs that are not met by cash from operations or other available funds. The $400 million in aggregate commitments under the credit agreement mature on December 7, 2028, unless earlier terminated in accordance with the agreement. As of December 31, 2025, we did not have any borrowings outstanding under this facility. As of December 31, 2024, we had outstanding under this facility $65.0 million in borrowings at a blended interest rate of 5.61%. As of December 31, 2025 and 2024, we did not have any letters of credit outstanding under this facility.

The credit agreement contains customary conditions to borrowing or the issuance of a letter of credit, representations and warranties and covenants. The credit agreement obligates us to maintain a debt to capitalization ratio of no more than 0.85 to 1.00 and to maintain a margins for interest ratio of no less than 1.10 times interest charges (calculated in accordance with our Indenture as currently in effect). Obligations under the credit agreement may be accelerated following, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the failure to pay outstanding principal when due or other amounts, including interest, within five days after the due date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a material misrepresentation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a cross-payment default or cross-acceleration under specified indebtedness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•failure by us to perform any obligation relating to the credit agreement following, in some cases, specified cure periods;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•bankruptcy or insolvency events;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•invalidity of the credit agreement and related loan documentation or our assertion of invalidity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a failure by our member distribution cooperatives to pay amounts in excess of an agreed threshold owing to us beyond a specified cure period.

**Financings**

We fund the portion of our capital expenditures that we are not able to fund from operations through borrowings under our revolving credit facility and issuances of debt in the capital markets. These capital expenditures consist primarily of the costs related to the development, construction, acquisition, expansion, or improvement of our owned generating and transmission facilities. We continue to evaluate the issuance of additional long-term indebtedness to fund capital expenditures related to our existing generating and transmission facilities. Additionally, we are evaluating the need to construct new or expand existing generating facilities, which could result in the issuance of additional long-term indebtedness. We believe our cash from operations, funds available from our revolving credit facility, and issuances of additional long-term indebtedness, will be sufficient to meet our currently anticipated future operational and capital requirements.

On December 16, 2025, we issued $250 million of long-term debt in a private placement transaction. The issuance consisted of $250 million first mortgage bonds due 2052 under the Indenture and proceeds were used to pay amounts outstanding under our revolving credit facility and for other general corporate purposes.

**Uses**

Our uses of liquidity and capital relate to funding our working capital needs, investment activities, and financing activities. Substantially all of our investment activities relate to capital expenditures in connection with our generating facilities. Additionally, we have asset retirement obligations in the future that are significantly offset by the nuclear decommissioning trust, which as of December 31, 2025, had a balance of $340.6 million. Our future contingent obligations primarily relate to power purchase and natural gas contracts, and we have no off-balance sheet obligations. Some of our power purchase contracts obligate us to provide

------

credit support if our obligations issued under the Indenture are rated below specified thresholds by S&P and Moody's. We currently anticipate that cash from operations, borrowings under our revolving credit facility, and potential issuances of long-term indebtedness will be sufficient to meet our liquidity needs for the near term, including planned capital expenditures, asset retirement obligations, and our contingent obligations as described above.

**Capital Expenditures** 

We regularly forecast our capital expenditures as part of our long-term business planning activities. We review these projections periodically in order to update our calculations to reflect changes in our future plans, projects currently under consideration, construction costs, market factors, and other items affecting our forecasts. Our actual capital expenditures could vary significantly from these projections. The table below summarizes our actual and projected capital expenditures on a cash flow basis, including capitalized interest, for 2023 through 2028:

| &nbsp;&nbsp;&nbsp;&nbsp;Total | $52.9 | $55.7 | $98.9 | $191.0 | $149.5 | $191.6 |

---

Nearly all of our capital expenditures consist of additions to electric plant and equipment. Capital expenditures for North Anna include $41.8 million, $34.4 million, and $29.2 million, for 2026, 2027, and 2028, respectively, for costs related to license extension. Projected capital expenditures for transmission include costs related to transmission facility upgrades in accordance with PJM planning processes. Projected capital expenditures for combustion turbine facilities include costs related to uprate projects. Projected capital expenditures for Clover for 2026 include costs related to the project to rebuild the main generator for Unit 2. We intend to use our cash flow from operations, funds from our 2025 debt issuance, borrowings under our revolving credit facility, and, if needed, issuances of additional debt in the capital markets to fund all of our currently projected capital requirements through 2028.

**Power Purchase and Natural Gas Agreements**

Under the terms of most of our power purchase and natural gas agreements, we typically agree to provide collateral under certain circumstances and require comparable terms from our counterparties. The collateral we may be required to post with a counterparty, and vice versa, is normally a function of the collateral thresholds we negotiate with a counterparty relative to a range of credit ratings as well as the value of our transaction(s) under a contract with a respective counterparty. As of December 31, 2025, we were not required to post collateral with counterparties pursuant to the power purchase and natural gas agreements we have in place.

Typically, collateral thresholds under our contracts are zero once an entity is rated below investment grade by S&P or Moody's (i.e., "BBB-" or "Baa3," respectively). As of December 31, 2025, if our credit ratings had been below investment grade we estimate we would have been obligated to post between $25 million and $75 million of collateral with our counterparties. This calculation is based on power and natural gas prices on December 31, 2025, and delivered power and natural gas for which we had not yet paid. Depending on the difference between the price of power and natural gas under our agreements and the price of power and natural gas in the market at the time of the calculation, this amount could increase or decrease. S&P, Moody's, and Fitch currently rate our outstanding obligations issued under our Indenture at "A+," "A1," and "A+,"

------

respectively. Additionally, we have an issuer credit rating of "A+" from S&P, and an implied senior unsecured rating of "A+" from Fitch.

PJM requires that we provide collateral to support our obligations in connection with certain PJM transactions and as of December 31, 2025, we had posted collateral totaling $7.6 million. In accordance with its credit policy, PJM subjects each member of PJM to a credit evaluation. A material change in our financial condition, including the downgrading of our credit rating by any rating agency, could cause PJM to re-evaluate our creditworthiness and require that we provide additional collateral. As of December 31, 2025, if PJM had determined that we needed to provide additional collateral to support our obligations as a result of our creditworthiness, PJM could have asked us to provide up to approximately $26.5 million.

**ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

The operation of our business exposes us to several common market risks, including changes in market prices for power and fuel, and interest rates and equity prices.

**Market Price Risk**

We are exposed to market price risk by purchasing power to supply the power requirements of our member distribution cooperatives that are not met by our owned generation. See "Power Supply Resources" in Item 1. In addition, the purchase of fuel to operate our generating facilities also exposes us to market price risk.

The fair value of the hedging instruments we use to mitigate market price risk is impacted by changes in market prices. As of December 31, 2025, we estimate that the fair value of our purchased power agreements, forward purchases of natural gas, and renewable energy credits held for sale was between $1.6 billion and $1.7 billion. Approximately 49% of the fair value of this portfolio is estimable using observable market prices. The remaining 51% of the fair value of this portfolio is related to less liquid products and the fair values of these products are not directly estimable using observable market prices. In the absence of observable market prices, the valuation of the 51% of this portfolio that relates to less liquid products involves management judgment, the use of estimates, and the underlying assumptions in our portfolio model. As a result, changes in estimates and underlying assumptions or use of alternate valuation methods could affect the estimated fair value of this portfolio. As an example of our portfolio's exposure to market price risk, we estimate that a 10% change in the price of the commodities hedged by the portion of this portfolio with observable market prices would have changed the fair value of this portion of the portfolio by approximately $81.2 million as of December 31, 2025. To the extent all or portions of our portfolio are liquidated above or below our original cost, these gains or losses are factored into the costs billed to our member distribution cooperatives pursuant to our formula rate. See "Factors Affecting Results—Formula Rate" in Item 7.

We have formulated policies and procedures to manage the risks associated with these market price fluctuations. Additionally, we use various hedging instruments, including forwards, futures, financial transmission rights, and options, to manage our power market price risks. ACES assists us in managing our market price risks by:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•maintaining a portfolio model that identifies our power producing resources (including our power purchase contract positions and generating capacity, and fuel supply, transportation, and storage arrangements) and analyzing the optimal use of these resources in light of costs and market risks associated with using these resources;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•modeling our power obligations and assisting us with analyzing alternatives to meet our member distribution cooperatives' power requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•selling excess power as our agent; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•executing hedge trades to stabilize the cost of fuel requirements, primarily natural gas used to operate our generating facilities.

------

We also are subject to market price risk relating to purchases of fuel for North Anna and Clover. We manage these risks indirectly through our participation in the management arrangements for these facilities. However, Virginia Power, as operator of these facilities, has the sole authority and responsibility to procure nuclear fuel and coal for North Anna and Clover, respectively.

**Interest Rate Risk and Equity Price Risk**

In 2025, all of our outstanding long-term debt accrued interest at fixed rates.

We maintain a revolving credit facility. See "Liquidity and Capital Resources—Sources—Revolving Credit Facility" in Item 7. Any amounts we borrow under this facility will accrue interest at a variable rate. As of December 31, 2025, we did not have any borrowings outstanding under this facility; however, the effective interest rate for any borrowings would have been 4.89%. As of December 31, 2024, we had outstanding under this facility $65.0 million in borrowings at a blended interest rate of 5.61%. As of December 31, 2025 and 2024 we did not have any letters of credit outstanding under this facility. We estimate that a 10% change in the weighted average interest rate would not have had a material effect on our interest expense as of December 31, 2025.

We accrue decommissioning costs over the expected service life of North Anna and have made periodic deposits to a trust so that the trust balance will cover the estimated costs to decommission North Anna at the time of decommissioning. As of December 31, 2025, $238.3 million and $101.9 million, were invested in equity securities and debt securities, respectively. The value of these debt and equity securities will be impacted by changes in interest rates and price fluctuations in debt and equity markets. To minimize adverse changes in the aggregate value of the trust, we actively monitor our portfolio by measuring the performance of the investments against market indices and by maintaining and reviewing established target allocation percentages of assets in the trust to various investment options. We believe the trust's exposure to changes in interest rates and price fluctuations in debt and equity markets will not have a material impact on our financial results.

Report of Management on ODEC's Internal Control over Financial Reporting

Management of Old Dominion Electric Cooperative ("ODEC") has assessed ODEC's internal control over financial reporting as of December 31, 2025, based on criteria for effective internal control over financial reporting described in the "2013 Internal Control – Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management believes that as of December 31, 2025, our system of internal control over financial reporting was properly designed and operating effectively based upon the specified criteria.

Management of ODEC is responsible for establishing and maintaining adequate internal control over financial reporting. ODEC's internal control over financial reporting is comprised of policies, procedures, and reports designed to provide reasonable assurance to ODEC's management and board of directors that the financial reporting and the preparation of the financial statements for external reporting purposes have been handled in accordance with accounting principles generally accepted in the United States. Internal control over financial reporting includes those policies and procedures that (1) govern records to accurately and fairly reflect the transactions and dispositions of assets of ODEC; (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 ODEC are being made only in accordance with authorizations of the management and directors of ODEC; and (3) provide reasonable safeguards against or timely detection of material unauthorized acquisition, use or disposition of ODEC's assets.

Internal controls over financial reporting may not prevent or detect all misstatements. Accordingly, even effective internal control can provide only reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with United States generally accepted accounting principles.

Report of Independent Registered Public Accounting Firm

To the Board of Directors and Members of Old Dominion Electric Cooperative

**Opinion on the Financial Statements**

We have audited the accompanying consolidated balance sheets of Old Dominion Electric Cooperative (the Cooperative) as of December 31, 2025 and 2024, the related consolidated statements of revenues, expenses, and patronage capital and cash flows for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Cooperative at December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

**Basis for Opinion**

These financial statements are the responsibility of the Cooperative's management. Our responsibility is to express an opinion on the Cooperative's financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Cooperative 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. The Cooperative is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Cooperative's internal control over financial reporting. Accordingly, we express no such opinion.

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 the critical audit matter does not alter in any way our opinion on the consolidated 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.

|:---|:---|
|  | &nbsp;&nbsp;***Accounting for Asset Retirement and Environmental Obligations*** |
| &nbsp;&nbsp;*Description of the Matter* | &nbsp;&nbsp;At December 31, 2025 the Cooperative's nuclear asset retirement obligation ("ARO") at North Anna totaled $188.9 million. As described in Note 3 to the consolidated financial statements, the Cooperative's ARO associated with the legal obligation to retire North Anna Unit 1 and Unit 2 is recognized at fair value when incurred and capitalized as part of the related long-lived asset. The ARO is based on estimates and assumptions including the cost and method of decommissioning and the timing of the related cash flows, and the license period of the nuclear plant. New decommissioning studies are performed periodically or whenever factors indicate that there could be a material change to the estimate. The Cooperative, with the assistance of third-party experts, performed an updated decommissioning study in 2024. The Cooperative is not aware of any events that have occurred since the 2024 study that would materially impact the ARO estimate.  |
| &nbsp;&nbsp;*Description of the Matter* | &nbsp;&nbsp; <br>Auditing the Cooperative's ARO was complex and highly judgmental due to the significant estimation required by management to determine the estimated present value of the legal obligation associated with the Cooperative's nuclear facility at North Anna. For example, the estimate was sensitive to significant assumptions including the estimated cost of decommissioning, the method of decommissioning and timing of related cash flows. Significant changes in management's estimate could have a material effect on the Cooperative's results of operations. |
| &nbsp;&nbsp;*How We Addressed the Matter in Our Audit* | &nbsp;&nbsp; <br>To test the ARO estimate, our audit procedures included testing the significant assumptions described above and the completeness and accuracy of the underlying data used by the Cooperative in its estimate. For example, we compared current year regulatory requirements and recent market data to the information used by the Cooperative. We involved a specialist to assist in our evaluation of the factors discussed above that could impact the Cooperative's retirement obligation.  |

**OLD DOMINION ELECTRIC COOPERATIVE**

**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**NOTE 1—Summary of Significant Accounting Policies**

**General**

The accompanying financial statements reflect the consolidated accounts of Old Dominion Electric Cooperative and TEC. In accordance with Consolidation Accounting, TEC is considered a variable interest entity for which we are the primary beneficiary. We have eliminated all intercompany balances and transactions in consolidation. The assets and liabilities, and non-controlling interest of TEC are recorded at carrying value and the consolidated assets were $6.9 million and $6.8 million, as of December 31, 2025 and December 31, 2024, respectively. The income taxes reported on our Consolidated Statements of Revenues, Expenses, and Patronage Capital relate to the tax provision for TEC, which is a taxable corporation. As TEC is 100% owned by our Class A members, its equity is presented as a non-controlling interest on our consolidated financial statements. Our non-controlling, 50% or less, ownership interest in other entities for which we have significant influence is recorded using the equity method of accounting. We have a power sales contract with TEC under which we may sell to TEC, power that we do not need to meet the needs of our member distribution cooperatives. TEC then sells this power to the market under market-based rate authority granted by FERC. During 2025 and 2024, we did not sell excess power to TEC. During 2023, we sold excess power to TEC, and TEC had sales to third parties. Additionally, we have a separate contract under which we may purchase natural gas from TEC; however, we have not purchased natural gas from TEC in recent years. TEC does not engage in speculative trading.

We are a not-for-profit wholesale power supply cooperative, incorporated under the laws of the Commonwealth of Virginia in 1948. We have two classes of members. Our eleven Class A members are customer-owned electric distribution cooperatives engaged in the retail sale of power to customers located in Virginia, Delaware, and Maryland. Our sole Class B member is TEC. Our board of directors is composed of two representatives from each of the member distribution cooperatives and one representative from TEC. Our rates are set periodically by a formula that was accepted for filing by FERC, and are not regulated by the public service commissions of the states in which our member distribution cooperatives operate.

We comply with the Uniform System of Accounts prescribed by FERC. In conformity with GAAP, the accounting policies and practices applied by us in the determination of rates are also employed for financial reporting purposes. The preparation of our consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported therein. Actual results could differ from those estimates. We did not have any other comprehensive income for the periods presented.

**Electric Plant**

Electric plant is stated at original cost when first placed in service. Such cost includes contract work, direct labor and materials, allocable overhead, an allowance for borrowed funds used during construction, and asset retirement costs. Upon the partial sale or retirement of plant assets, the original asset cost and current disposal costs less sale proceeds, if any, are charged or credited to accumulated depreciation. In accordance with industry practice, no profit or loss is recognized in connection with normal sales and retirements of property units.

Maintenance and repair costs are expensed as incurred. Replacements and renewals of items considered to be units of property are capitalized to the property accounts.

------

**Depreciation** 

We use the group method of depreciation and periodically conduct depreciation studies and update rates, if necessary. Our depreciation rates for the past three years were as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | **Depreciation Rates** | **Depreciation Rates** | **Depreciation Rates** |
| **Generating Facility** | **2025** | **2024** | **2023** |
| Wildcat Point | 3.1% | 3.1% | 3.1% |
| North Anna | 3.3 | 3.3 | 3.3 |
| Clover | 1.9 | 1.9 | 1.9 |
| Louisa | 3.1 | 3.1 | 3.1 |
| Marsh Run | 3.0 | 3.0 | 3.0 |

---

**Nuclear Fuel**

Nuclear fuel is amortized on a unit of production basis sufficient to fully amortize the cost of fuel over its estimated service life and is recorded in fuel expense.

Virginia Power, as operating agent of North Anna, has the sole authority and responsibility to procure nuclear fuel for the facility. Virginia Power advises us that it primarily uses long-term contracts to support North Anna's nuclear fuel requirements and that worldwide market conditions are continuously evaluated to ensure a range of fuel supply options at reasonable prices, which are dependent upon the market environment. We are not a direct party to any of these procurement contracts and we do not control their terms, conditions, or duration. Virginia Power advises us that current agreements, inventories, and spot market availability are expected to support North Anna's current and planned fuel supply needs for the near term and that additional fuel is purchased as required to attempt to ensure optimal cost and inventory levels.

Under the Nuclear Waste Policy Act of 1982, the DOE is required to provide for the permanent disposal of spent nuclear fuel produced by nuclear facilities, such as North Anna, in accordance with contracts executed with the DOE. The DOE did not begin accepting spent fuel in 1998 as specified in its contract with Virginia Power. As a result, Virginia Power sought reimbursement for certain spent nuclear fuel-related costs incurred and in 2012 signed a settlement agreement with the DOE. By mutual agreement of the parties, the settlement agreement is extendable to provide for resolution of damages. In December 2025, the DOE provided notification that it intends to extend the settlement agreement to provide for periodic payments for damages incurred through December 31, 2028, and future additional extensions are contemplated by the settlement agreement. We continue to recognize receivables for certain spent nuclear fuel-related costs. We believe the recovery of these costs from the DOE is probable. As of December 31, 2025 and 2024, we had an outstanding receivable of $3.2 million and $3.7 million, respectively.

**Fuel, Materials, and Supplies**

Fuel, materials, and supplies is primarily composed of fuel and spare parts for our generating assets, renewable energy credits, and emission allowances, all of which are recorded at cost. Fuel consists primarily of coal and No. 2 fuel oil.

**Allowance for Borrowed Funds Used During Construction**

Allowance for borrowed funds used during construction is defined as the net cost of borrowed funds used for construction purposes during the construction period and a reasonable rate on other funds when so used. We capitalize interest on borrowings for significant construction projects. Interest capitalized in 2025, 2024, and 2023, was $3.3 million, $2.3 million, and $1.4 million, respectively.

**Income Taxes** 

We are a not-for-profit wholesale power supply cooperative and currently are exempt from federal income taxation under IRC Section 501(c)(12). In order to maintain our tax-exempt status, we must receive at least 85%

------

of our income from our members on an annual basis. We maintained our tax-exempt status as of December 31, 2025.

TEC is a taxable corporation and its provision for income taxes was immaterial for the years ended December 31, 2025, 2024, and 2023.

**Zero-emission Nuclear Power Production Tax Credit**

The Inflation Reduction Act of 2022 provides for the zero-emission nuclear power production tax credit for electricity produced at a qualified nuclear power facility, including North Anna, and sold to an unrelated third party beginning in 2024. In November 2025, we filed a claim for $24.3 million in zero-emission nuclear power production tax credit and elected direct pay reimbursement for tax year 2024 based on existing guidance. Additionally, we recorded $19.2 million in zero-emission nuclear power production tax credit for tax year 2025 that we expect to seek direct pay reimbursement to be reflected on our 2025 tax return. We have established a receivable as well as a regulatory liability for $43.5 million. The ultimate zero-emission nuclear power production tax credit realized by us may vary significantly based on future IRS guidance.

**Operating Revenues**

Our operating revenues are derived from sales of power and renewable energy credits to our members and non-members. We supply power requirements (energy and demand) to our eleven member distribution cooperatives subject to substantially identical wholesale power contracts with each of them. We bill our member distribution cooperatives monthly and each member distribution cooperative is required to pay us monthly for power furnished under its wholesale power contract. See Note 5—Wholesale Power Contracts. We transfer control of the electricity over time and our member distribution cooperatives simultaneously receive and consume the benefits of the electricity. The amount we invoice our member distribution cooperatives on a monthly basis corresponds directly to the value to the member distribution cooperatives of our performance, which is determined by our formula rate included in the wholesale power contract. We sell excess energy and renewable energy credits to non-members at prevailing market prices as control is transferred.

ODEC sells excess purchased and generated energy not needed to meet the actual needs of our member distribution cooperatives to PJM, TEC, or other counterparties. Our financial statements represent the consolidated financial statements of ODEC and TEC and through the consolidation process, all intercompany balances and transactions have been eliminated and TEC's sales are reflected as non-member revenues.

The rates we charge our member distribution cooperatives are regulated by FERC and FERC has granted us authority to charge our member distribution cooperatives utilizing both a formula rate and market-based rates.

---

<sup>(1)</sup> TEC did not have sales to non-members in 2025 and 2024. TEC's sales to non-members were $8.9 million for the year ended December 31, 2023.

**Formula Rate**

Our power sales are comprised of two power products – energy and demand. Energy is the physical electricity delivered through transmission and distribution facilities to customers. We must have sufficient committed energy available to us for delivery to our member distribution cooperatives to meet their maximum energy needs at any time, with limited exceptions. This committed available energy at any time is referred to as demand.

The rates we charge our member distribution cooperatives are regulated by FERC and FERC has granted us authority to charge our member distribution cooperatives utilizing both a formula rate and market-based rates. In accordance with our wholesale power contracts with our member distribution cooperatives, we sell power to them utilizing a formula rate. An exception in the formula rate allows our member distribution cooperatives to elect to utilize market-based rates for new and expanding loads that meet certain criteria.

The rates we charge our member distribution cooperatives under the formula rate are intended to permit collection of revenues which will equal the sum of:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•all of our costs and expenses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•20% of our total interest charges (margin requirement); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•additional equity contributions approved by our board of directors.

The formula rate identifies the cost components that we can collect through rates, but not the actual amounts to be collected. With limited minor exceptions, we can change our rates periodically to match the costs we have incurred and we expect to incur without seeking FERC approval.

Energy costs, which are primarily variable costs, such as natural gas, nuclear, and coal fuel costs, and the energy costs under our power purchase contracts with third parties, are recovered through two separate rates, the base energy rate and the energy adjustment rate (collectively referred to as the total energy rate). The base

------

energy rate is developed annually to collect energy costs as estimated in our budget including amounts in the deferred energy account from the prior year. As of January 1 of each year, the base energy rate is reset in accordance with our budget and the energy adjustment rate is reset to zero. We can revise the energy adjustment rate during the year if it becomes apparent that the total energy rate is over-collecting or under-collecting our actual and anticipated energy costs. Any revision to the energy adjustment rate requires board approval and that the resulting change to the total energy rate is at least 2%.

Demand costs, which are primarily fixed costs, such as capacity costs under power purchase contracts with third parties, transmission costs, administrative and general expenses, depreciation expense, interest expense, margin requirement, and additional equity contributions approved by our board of directors, are recovered through our demand rates. The formula rate allows us to change the actual demand rates we charge as our demand-related costs change, without FERC approval, with the exception of decommissioning cost, which is a fixed number in the formula rate that requires FERC approval prior to any adjustment. FERC approval is also needed to change account classifications currently in the formula or to add accounts not otherwise included in the current formula. Additionally, depreciation studies are required to be filed with FERC for its approval if they would result in a change in our depreciation rates. We collect our total demand costs through the following three separate rates:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•transmission service rate – designed to collect transmission-related and distribution-related costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•RTO capacity service rate – designed to collect capacity costs in PJM that PJM allocates to ODEC and other PJM members; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•remaining owned capacity service rate – designed to collect all remaining demand costs not billed and/or recovered under the transmission service and RTO capacity service rates.

As stated above, our margin requirement and additional equity contributions approved by our board of directors are recovered through our demand rates. We establish our demand rates to produce a net margin attributable to ODEC equal to 20% of our budgeted total interest charges, plus additional equity contributions approved by our board of directors. The formula rate permits us to adjust revenues from the member distribution cooperatives to equal our actual total demand costs incurred, including a net margin attributable to ODEC equal to 20% of actual interest charges, plus additional equity contributions approved by our board of directors. We make these adjustments utilizing Margin Stabilization. See "Margin Stabilization" below.

We may revise our budget at any time to the extent that our current budget does not accurately reflect our costs and expenses or estimates of our sales of power. Increases or decreases in our budget automatically amend the energy and/or the demand components of our formula rate, as necessary. If at any time our board of directors determines that the formula does not recover all of our costs and expenses or determines a change in cost allocation methodology among our member distribution cooperatives is appropriate, it may adopt a new formula to meet those costs and expenses, subject to any necessary regulatory review and approval.

**Margin Stabilization**

Margin Stabilization allows us to review our actual demand-related costs of service and demand revenues and adjust revenues from our member distribution cooperatives to meet our financial coverage requirements and accumulate additional equity as approved by our board of directors. Our formula rate allows us to collect and return amounts utilizing Margin Stabilization. We record all adjustments, whether increases or decreases, in the year affected and allocate any adjustments to our member distribution cooperatives based on power sales during that year. We collect these increases from our member distribution cooperatives, or offset decreases against amounts owed by our member distribution cooperatives to us, generally in the succeeding calendar year. We adjust operating revenues and accounts receivable–members or accounts payable–members, as appropriate, to reflect these adjustments. These adjustments are treated as due, owed, incurred, and accrued for the year to which the adjustment relates. The following table details the reduction in revenues utilizing Margin Stabilization for the past three years:

------

---

| | | | |
|:---|:---|:---|:---|
|  | **Year Ended December 31,** | **Year Ended December 31,** | **Year Ended December 31,** |
|  | **2025** | **2024** | **2023** |
|  | (in thousands) | (in thousands) | (in thousands) |
| Margin Stabilization adjustment | $14544 | $8349 | $3298 |

**Member Power Bill Payment Plan**

We maintain a program which allows our member distribution cooperatives to prepay or extend payment on their monthly power bills. Under this program, we pay interest on prepayment balances at a blended investment and short-term borrowing rate, and we charge interest on extended payment balances at a blended prepayment and short-term borrowing rate. Amounts prepaid by our member distribution cooperatives are included in accounts payable–members and as of December 31, 2025 and 2024, were $0.8 million and $58.4 million, respectively. Amounts extended to our member distribution cooperatives are included in accounts receivable–members and as of December 31, 2025 and 2024, were $29.1 million and $16.0 million, respectively.

**Regulatory Assets and Liabilities**

We account for certain revenues and expenses as a rate-regulated entity in accordance with Accounting for Regulated Operations. This allows certain of our revenues and expenses to be deferred at the discretion of our board of directors, which has budgetary and rate setting authority, if it is probable that these amounts will be collected or returned through our formula rate in future periods. Regulatory assets represent costs that we expect to collect from our member distribution cooperatives based on rates approved by our board of directors in accordance with our formula rate. Regulatory liabilities represent probable future reductions in our revenues associated with amounts that we expect to return to our member distribution cooperatives based on rates approved by our board of directors in accordance with our formula rate. See "Formula Rate" above. Regulatory assets are generally included in deferred charges and other assets, and regulatory liabilities are generally included in deferred credits and other liabilities. Deferred energy, which can be either a regulatory asset or a regulatory liability, is included in current assets or current liabilities, respectively. See "Deferred Energy" below. We recognize regulatory assets and liabilities as expenses or as a reduction in expenses, respectively, concurrent with their collection or return through rates.

**Debt Issuance Costs**

Capitalized costs associated with the issuance of long-term debt totaled $5.2 million and $4.0 million as of December 31, 2025 and 2024, respectively, and are included as a direct reduction to long-term debt. Capitalized costs associated with our revolving credit facility totaled $0.4 million and $0.5 million as of December 31, 2025 and 2024, respectively, and are recorded in other assets. These costs are being amortized using the effective interest method over the life of the respective long-term debt issuances and revolving credit facility, and are included in interest charges, net.

**Deferred Energy**

In accordance with Accounting for Regulated Operations, we use the deferral method of accounting to recognize differences between our energy revenues collected from our member distribution cooperatives and our energy expenses. The deferred energy balance represents the net accumulation of any under- or over-collection of energy costs. Under-collected energy costs appear as an asset and will be collected from our member distribution cooperatives in subsequent periods through our formula rate. Conversely, over-collected energy costs appear as a liability and will be returned to our member distribution cooperatives in subsequent periods through our formula rate. As of December 31, 2025 and 2024, we had an over-collected deferred energy balance of $59.0 million and $100.8 million, respectively.

The following table summarizes the changes to our total energy rate since 2023, which were implemented to address the differences in our realized as well as projected energy costs:

------

---

| | |
|:---|:---|
| **Effective Date of Rate Change** | **% Change** |
| January 1, 2023 | (1.5) |
| August 1, 2023 | (14.8) |
| January 1, 2024 | (7.0) |
| July 1, 2024 | (3.5) |
| January 1, 2025 | (6.4) |
| June 1, 2025 | 16.4 |
| January 1, 2026 | (1.1) |

---

**Financial Instruments (including Derivatives)**

Investments included in the nuclear decommissioning trust are carried at fair value. Unrealized gains and losses on investments held in the nuclear decommissioning trust are deferred as a regulatory liability or a regulatory asset, respectively, until realized.

Unrestricted investments in debt securities that we have the positive intent and ability to hold to maturity are recorded at amortized cost. Non-marketable equity investments, which are accounted for under the equity method, are included in other investments and recorded at cost. Equity securities in other investments are recorded at fair value. See Note 8—Investments.

We primarily purchase power under both long-term and short-term physically-delivered forward contracts to supply power to our member distribution cooperatives. These forward purchase contracts meet the accounting definition of a derivative; however, a majority of these forward purchase derivative contracts qualify for the normal purchases/normal sales accounting exception under Accounting for Derivatives and Hedging. As a result, these contracts are not recorded at fair value. We record a liability and purchased power expense when the power under the physically-delivered forward contract is delivered. We also purchase natural gas futures generally for five years or less to hedge the price of natural gas for our facilities which utilize natural gas. These derivatives do not qualify for the normal purchases/normal sales accounting exception.

For all derivative contracts that do not qualify for the normal purchases/normal sales accounting exception, we defer all unrealized gains and losses on a net basis as a regulatory liability or regulatory asset, respectively, in accordance with Accounting for Regulated Operations. See "Regulatory Assets and Liabilities" above. These amounts are subsequently reclassified as purchased power or fuel expense as the power or fuel is delivered and/or the contract settles.

Generally, derivatives are reported at fair value in other assets and other liabilities. The measurement of fair value is based on actively quoted market prices, if available. Otherwise, we seek indicative price information from external sources, including broker quotes and industry publications. For individual contracts, the use of differing assumptions could have a material effect on the contract's estimated fair value.

**Patronage Capital**

We are organized and operate as a cooperative. Patronage capital represents our retained net margins, which have been allocated to our members based upon their respective power purchases in accordance with our bylaws. Any distributions of patronage capital are subject to the discretion of our board of directors and the restrictions contained in our Indenture. See Note 10—Long-term Debt for discussion of the restrictions contained in the Indenture.

We operate on a not-for-profit basis and, accordingly, seek to generate revenues sufficient to recover our cost of service and produce margins sufficient to establish reasonable reserves, meet financial coverage requirements, and accumulate additional equity approved by our board of directors. Revenues in excess of expenses in any year are designated as net margin attributable to ODEC on our Consolidated Statements of Revenues, Expenses, and Patronage Capital. We designate retained net margins attributable to ODEC on our Consolidated Balance Sheet as patronage capital, which we assign to each of our members on the basis of its class of membership and business with us.

------

Our board of directors approved an additional equity contribution of $38.5 million that was collected in 2025, and an additional equity contribution of $27.5 million that will be collected in 2026. Additional equity contributions are collected through rates charged to our member distribution cooperatives and are used to fund future capital expenditures.

**Concentrations of Credit Risk**

Financial instruments that potentially subject us to concentrations of credit risk consist of cash equivalents, investments, derivatives, and receivables arising from sales to our members and non-members. Concentrations of credit risk with respect to receivables arising from sales to our member distribution cooperatives as reflected by accounts receivable–members were $156.1 million and $118.2 million, as of December 31, 2025 and 2024, respectively.

**Segment**

We are organized for the purpose of supplying the power our member distribution cooperatives require to serve their customers on a cost-effective basis. Our President and CEO serves as our chief decision-maker who manages and reviews our operating results as one operating, and therefore one reportable, segment. We supply our member distribution cooperatives' energy and demand requirements through a portfolio of resources including generating facilities, physically-delivered forward power purchase contracts, and spot market energy purchases.

**Cash and Cash Equivalents**

For purposes of our Consolidated Statements of Cash Flows, we consider all unrestricted highly liquid debt instruments purchased with an original maturity of three months or less to be cash equivalents.

**NOTE 2—Electric Plant**

Our net electric plant was composed of the following as of December 31, 2025:

**Wildcat Point**

We own Wildcat Point, a 980 MW (net capacity entitlement) natural gas-fueled combined cycle generation facility.

**North Anna**

We hold an 11.6% undivided ownership interest in North Anna, a two-unit, 1,892 MW (net capacity entitlement) nuclear power generation facility operated by Virginia Power, which owns the balance of the plant. We are responsible for and must fund 11.6% of all post-acquisition date additions and operating costs associated with North Anna, as well as a pro-rata portion of Virginia Power's administrative and general expenses directly attributable to North Anna. Our portion of assets, liabilities, and operating expenses associated with North Anna are included on our consolidated financial statements in accordance with proportionate consolidation accounting. As of December 31, 2025 and 2024, we had an outstanding accounts payable balance of $13.3 million and $10.7 million, respectively, due to Virginia Power for operation, maintenance, and capital investment at North Anna.

**Clover**

We hold a 50% undivided ownership interest in Clover, a two-unit, 877 MW (net capacity entitlement) coal-fired generation facility operated by Virginia Power, which owns the balance of the plant. We are responsible for and must fund half of all additions and operating costs associated with Clover, as well as half of Virginia Power's administrative and general expenses directly attributable to Clover. Our portion of assets, liabilities, and operating expenses associated with Clover are included on our consolidated financial statements in accordance with proportionate consolidation accounting. As of December 31, 2025 and 2024, we had an outstanding accounts payable balance of $16.3 million and $10.7 million, respectively, due to Virginia Power for operation, maintenance, and capital investment at Clover.

**Combustion Turbine Facilities**

We own two combustion turbine facilities, Louisa and Marsh Run, each 504 MW, that are primarily fueled by natural gas.

**Other**

We also own six distributed generation facilities, and approximately 110 miles of transmission lines on the Virginia portion of the Delmarva Peninsula.

**NOTE 3—Accounting for Asset Retirement and Environmental Obligations**

We account for our asset retirement obligations in accordance with Accounting for Asset Retirement and Environmental Obligations. This requires that legal obligations associated with the retirement of long-lived assets be recognized at fair value when incurred and capitalized as part of the related long-lived asset. Over time, the liability is accreted to its present value each period, and the capitalized asset is depreciated over the useful life of the long-lived asset.

In the absence of quoted market prices, we estimate the fair value of our asset retirement obligations using present value techniques, in which estimates of future cash flows associated with retirement activities are discounted using a credit-adjusted risk-free rate. Our estimated liability could change significantly if actual costs vary from assumptions or if governmental regulations change significantly.

A significant portion of our asset retirement obligations relates to our share of the future costs to decommission North Anna. As of December 31, 2025 and 2024, our share of North Anna's nuclear decommissioning asset retirement obligation totaled $188.9 million and $183.2 million, respectively. Periodically, a new decommissioning study for North Anna is performed by third-party experts. A new study was performed in 2024, and we adopted it effective December 31, 2024, which resulted in an additional layer related to the asset retirement obligation associated with North Anna. The additional layer resulted in an increase to our asset retirement cost and our asset retirement obligation of $6.8 million. The increase is related to costs associated with spent fuel as a result of the DOE delay for acceptance of spent fuel, as well as the change in the

------

market risk premium and inflation rates utilized to calculate our costs. We are required to maintain a funded trust to satisfy our future obligation to decommission the North Anna facility. See Note 8—Investments.

The following represents changes in our asset retirement obligations for the years ended December 31, 2025 and 2024 (in thousands):

---

| | |
|:---|:---|
| Asset retirement obligations as of December 31, 2023 | $196747 |
| &nbsp;&nbsp;&nbsp;&nbsp;Accretion expense | 6289 |
| &nbsp;&nbsp;&nbsp;&nbsp;Increase in asset retirement obligations - new layer | 6836 |
| Asset retirement obligations as of December 31, 2024 | $209872 |
| &nbsp;&nbsp;&nbsp;&nbsp;Accretion expense | 6919 |
| Asset retirement obligations as of December 31, 2025 | $216791 |

---

The cash flow estimates for North Anna's asset retirement obligation are based upon the life of Unit 1 to April 1, 2058, and the life of Unit 2 to August 21, 2060. Virginia Power, the co-owner of North Anna, submitted an application to the NRC in August 2020 for this additional 20-year operating license extension for North Anna and in August 2024 the NRC granted the license extensions reflected above. Given the life extension, the nuclear decommissioning trust was, and currently is, estimated to be adequate to fund North Anna's asset retirement obligation and no additional funding was, or is, currently required. We ceased collection of decommissioning expense in August 2003 with the approval of FERC. As we are not currently collecting decommissioning expense in our rates, we are deferring the difference between the earnings on the nuclear decommissioning trust and the total asset retirement obligation related depreciation and accretion expense for North Anna as part of our asset retirement obligation regulatory liability. See Note 9—Regulatory Assets and Liabilities.

**NOTE 4—Power Purchase Agreements** 

In 2025, 2024, and 2023, our owned generating facilities together furnished approximately 44.7%, 43.6%, and 52.5%, respectively, of our energy requirements. The remaining needs were satisfied through purchases of power in the market through long-term and short-term physically-delivered forward power purchase contracts. We also purchased power in the spot energy market. This approach to meeting our member distribution cooperatives' energy requirements is not without risks. To mitigate these risks, we attempt to match our energy purchases with our energy needs to reduce our spot market purchases of energy and sales of excess energy. Additionally, we utilize policies, procedures, and various hedging instruments to manage our power market price risks. These policies and procedures, developed in consultation with ACES, an energy trading and risk management company, are designed to strike an appropriate balance between minimizing costs and reducing energy cost volatility. We are required to post collateral from time to time due to changes in power prices. As of December 31, 2025 and 2024, we were not required to post collateral with counterparties. Additionally, PJM requires that we provide collateral to support our obligations in connection with certain PJM transactions. As of December 31, 2025 and 2024, we had posted $7.6 million and $13.1 million, respectively.

Our purchased power expense, which includes the cost of purchased energy and capacity, for 2025, 2024, and 2023 was $543.3 million, $362.3 million, and $312.8 million, respectively.

As of December 31, 2025, our power purchase obligations under the various agreements were as follows:

---

| | |
|:---|:---|
| **Year Ended December 31,** | **Capacity and Energy<br>Obligations** |
|  | (in millions) |
| 2026 | $143.6 |
| 2027 | 104.1 |
| 2028 | 32.9 |
|  | $280.6 |

**NOTE 5—Wholesale Power Contracts** 

Our financial relationships with our member distribution cooperatives are based primarily on our contractual arrangements for the supply of power and related transmission and ancillary services. These arrangements are set forth in our wholesale power contracts with our member distribution cooperatives that are effective until January 1, 2079, and beyond this date unless either party gives the other at least three years notice of termination. The wholesale power contracts are all-requirements contracts. Each contract obligates us to sell and deliver to a member distribution cooperative, and obligates that member distribution cooperative to purchase and receive from us, all power that it requires for the operation of its system, with some exceptions, to the extent that we have the power and facilities available to do so.

An exception to the all-requirements obligations of our member distribution cooperatives relates to the ability of our eight mainland Virginia member distribution cooperatives to purchase hydroelectric power allocated to them from SEPA, a federal power marketing administration. Purchases under this exception constituted less than 1% of our member distribution cooperatives' total energy requirements in 2025.

There are two additional exceptions to the all-requirements nature of our wholesale power contracts.

One exception permits each of our member distribution cooperatives, with 180 days prior written notice, to receive up to the greater of 5% of its demand and associated energy or 5 MW of demand and associated energy from its owned generation or other suppliers. The member distribution cooperative may return this load with proper notice. If all of our member distribution cooperatives elected to fully utilize this exception, we estimate the current impact on our load requirements would be a reduction of approximately 183 MW of demand and associated energy. As of December 31, 2025, approximately 16 MW of demand and associated energy had been removed under this provision. We do not anticipate that the current or potential full utilization of this exception or the return of all removed load by our member distribution cooperatives would have a material impact on our results of operations, financial condition, or cash flows.

The second exception permits a member distribution cooperative to purchase additional power from other suppliers following approval by our board of directors. In this case, if an opportunity is presented to a member distribution cooperative to purchase a component of its all-requirements service from another supplier in excess of the first exception described above, the member distribution cooperative must offer that opportunity to us. If we decline the opportunity or we are otherwise unable to agree on an acceptable contract with the supplier, then the member distribution cooperative may purchase that component of service from the other supplier, subject to our ability to eliminate other purchases and a determination by our board of directors that use of the exception will not materially adversely affect us or our other member distribution cooperatives. Beginning in 2024, opportunities to purchase the power requirements to serve substantially large loads were presented to us, and we declined the opportunities. We continue to evaluate these opportunities as they arise.

Each member distribution cooperative is required to pay us monthly for the power we furnish under its wholesale power contract in accordance with our formula rate or under a market-based rate that a member distribution cooperative may elect in lieu of the formula rate for certain new and expanding loads. The formula rate, which has been filed with and accepted by FERC, is designed to recover our total cost of service and create a firm equity base. See Note 1—Summary of Significant Accounting Policies—Formula Rate.

More specifically, the formula rate is intended to meet all of our costs, expenses, and financial obligations associated with our ownership, operation, maintenance, repair, replacement, improvement, modification, retirement, and decommissioning of our generating plants, transmission system, or related facilities; services provided to the member distribution cooperatives; and the acquisition and transmission of power or related services, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•payments of principal and premium, if any, and interest on all our indebtedness (other than payments resulting from the acceleration of the maturity of the indebtedness);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•any additional cost or expense, imposed or permitted by any regulatory agency; and

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•additional amounts necessary to meet the requirement of any rate covenant with respect to coverage of principal and interest on our indebtedness contained in any indenture or contract with holders of our indebtedness.

The rates established under the wholesale power contracts are designed to enable us to comply with financing, regulatory, and governmental requirements that apply to us from time to time.

In accordance with the wholesale power contracts, our board of directors will review our formula rate at least every three years to determine if it reflects and recovers all costs and expenses indicated above, and if it represents the best way to allocate these costs and expenses among our member distribution cooperatives. In making this review, our board of directors will consider if the formula rate results in the proper price signals to our member distribution cooperatives. Due to changes in the energy sector generally and PJM specifically, the review of our formula rate often identifies new or changing bases for the costs we incur. We will not modify our formula rate in any manner that would result in a failure to recover all of our costs and other amounts described above.

Revenues from our member distribution cooperatives for the past three years were as follows:

**NOTE 6—Fair Value Measurements**

The fair value hierarchy gives the highest priority to quoted prices in active markets (Level 1) and the lowest priority to unobservable data (Level 3). In some cases, the inputs used to measure fair value might fall in different levels of the fair value hierarchy. The lowest level input that is significant to a fair value measurement in its entirety determines the applicable level in the fair value hierarchy. Assessing the significance

------

of a particular input to the fair value measurement in its entirety requires judgment, considering factors specific to the asset or liability.

The following table summarizes our financial assets and liabilities measured at fair value on a recurring basis as of December 31, 2025 and 2024:

<sup>(1)</sup> For additional information about our nuclear decommissioning trust, see Note 8—Investments.

<sup>(2)</sup> Nuclear decommissioning trust includes investments measured at net asset value per share (or its equivalent) as a practical expedient and these investments have not been categorized in the fair value hierarchy. The fair value amounts presented in this table are intended to permit reconciliation of the fair value hierarchy to the amounts presented in the Consolidated Balance Sheet.

<sup>(3)</sup> Unrestricted investments and other includes investments that are related to equity securities.

<sup>(4)</sup> Derivatives - gas and power represent natural gas futures contracts (Level 1 and Level 2) and financial transmission rights (Level 3). Level 1 are indexed against NYMEX. Level 2 are valued by ACES using observable market inputs for similar transactions. Level 3 are valued by ACES using unobservable market inputs, including situations where there is little market activity. Sensitivity in the market price of financial transmission rights could impact the fair value. For additional information about our derivative financial instruments, see Note 1—Summary of Significant Accounting Policies—Financial Instruments (including Derivatives).

------

**NOTE 7—Derivatives and Hedging**

We are exposed to market price risk by purchasing power to supply the power requirements of our member distribution cooperatives that are not met by our owned generation. In addition, the purchase of fuel to operate our generating facilities also exposes us to market price risk. To manage this exposure, we utilize derivative instruments. See Note 1—Summary of Significant Accounting Policies—Financial Instruments (including Derivatives).

Changes in the fair value of our derivative instruments accounted for at fair value are recorded as a regulatory asset or regulatory liability. The change in these accounts is included in the operating activities section of our Consolidated Statements of Cash Flows.

Outstanding derivative instruments, excluding contracts accounted for as normal purchase/normal sale, were as follows:

| Regulatory Liabilities included in Current Liabilities: |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Deferred energy | $59025 | $100806 |

---

The regulatory assets will be recognized as expenses concurrent with their collection through rates and the regulatory liabilities will be recognized as reductions to expenses concurrent with their return through rates.

Regulatory assets included in deferred charges and other assets are detailed as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Unamortized losses on reacquired debt are the costs we incurred to purchase our outstanding indebtedness prior to its scheduled retirement. These losses are amortized over the life of the original indebtedness and will be fully amortized in 2028.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred asset retirement costs reflect the cumulative effect of change in accounting principle for the Clover and distributed generation facilities as a result of the adoption of Accounting for Asset Retirement and Environmental Obligations. These costs will be fully amortized in 2034.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•NOVEC contract termination fee reflects the amount allocated to the contract value of the payment to NOVEC in 2008 as part of the termination agreement. The wholesale power contract with NOVEC was scheduled to expire in 2028, thus the contract termination fee will be amortized ratably through 2028.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Interest rate hedge. To mitigate a portion of our exposure to fluctuations in long-term interest rates related to the debt we issued in 2011, we entered into an interest rate hedge. This will be amortized over the life of the 2011 debt and will be fully amortized in 2050.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred net unrealized losses on derivative instruments will be matched and recognized in the same period the expense is incurred for the hedged item.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred transmission costs were amortized in 2025.

Regulatory liabilities included in deferred credits and other liabilities are detailed as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•North Anna asset retirement obligation deferral is the cumulative effect of change in accounting principle as a result of the adoption of Accounting for Asset Retirement and Environmental Obligations plus the deferral of subsequent activity primarily related to accretion expense offset by interest income on the nuclear decommissioning trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•North Anna nuclear decommissioning trust unrealized gain (net of losses) reflects the unrealized gain on the investments in the nuclear decommissioning trust.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred net unrealized gains on derivative instruments will be matched and recognized in the same period the expense is incurred for the hedged item.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred zero-emission nuclear power production tax credit reflects the deferred tax credits totaling $43.5 million. See Note 1—Summary of Significant Accounting Policies—Zero-emission Nuclear Power Production Tax Credit.

Regulatory liabilities included in current liabilities are detailed as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Deferred energy represents the net accumulation of over-collection of energy costs. We use the deferral method of accounting to recognize differences between our energy revenues collected from our member distribution cooperatives and our energy expenses. Over-collected deferred energy balances are returned to our member distribution cooperatives in subsequent periods.

As of December 31, 2025 and 2024, deferred gains and losses on reacquired debt totaled a net loss of approximately $0.3 million and $0.4 million, respectively. Deferred gains and losses on reacquired debt are deferred under regulatory accounting. See Note 9—Regulatory Assets and Liabilities.

Maturities of long-term debt for the next five years and thereafter are as follows:

---

| | |
|:---|:---|
| **Year Ended December 31,** | (in thousands) |
| 2026 | $49041 |
| 2027 | 49041 |
| 2028 | 49041 |
| 2029 | 36542 |
| 2030 | 36542 |
| 2031 and thereafter | 908666 |
|  | $1128873 |

---

The aggregate fair value of long-term debt was $1,038.3 million and $825.3 million as of December 31, 2025 and 2024, respectively, based on current market prices. For debt issues that are not quoted on an exchange, interest rates currently available to us for issuance of debt with similar terms and remaining maturities are used to estimate fair value.

------

All of our long-term debt is secured under our Indenture. Substantially all of our real property and tangible personal property and some of our intangible personal property are pledged as collateral under the Indenture. Under the Indenture, we may not make any distribution, including a dividend or payment or retirement of patronage capital, to our members if an event of default exists under the Indenture. Otherwise, we may make a distribution to our members if (1) after the distribution, our patronage capital as of the end of the most recent fiscal quarter would be equal to or greater than 20% of our total long-term debt and patronage capital, or (2) all of our distributions for the year in which the distribution is to be made do not exceed 5% of the patronage capital as of the end of the most recent fiscal year. For this purpose, patronage capital and total long-term debt do not include any earnings retained in any of our subsidiaries or affiliates or the debt of any of our subsidiaries or affiliates.

Additionally, we maintain a revolving credit facility. See Note 11—Liquidity Resources.

**NOTE 11—Liquidity Resources**

We maintain a revolving credit facility to cover our short-term and medium-term funding needs that are not met by cash from operations or other available funds. The $400 million in aggregate commitments under the credit agreement mature on December 7, 2028, unless earlier terminated in accordance with the agreement. As of December 31, 2025, we did not have any amounts outstanding under this facility; however the interest rate would have been 4.89%. As of December 31, 2024, we had outstanding under this facility $65.0 million in borrowings at a blended interest rate of 5.61%. As of December 31, 2025 and 2024, we did not have any letters of credit outstanding under this facility.

The credit agreement contains customary conditions to borrowing or the issuance of a letter of credit, representations and warranties and covenants. The credit agreement obligates us to maintain a debt to capitalization ratio of no more than 0.85 to 1.00 and to maintain a margins for interest ratio of no less than 1.10 times interest charges (calculated in accordance with our Indenture as currently in effect). Obligations under the credit agreement may be accelerated following, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the failure to pay outstanding principal when due or other amounts, including interest, within five days after the due date;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a material misrepresentation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a cross-payment default or cross-acceleration under specified indebtedness;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•failure by us to perform any obligation relating to the credit agreement following, in some cases, specified cure periods;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•bankruptcy or insolvency events;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•invalidity of the credit agreement and related loan documentation or our assertion of invalidity; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•a failure by our member distribution cooperatives to pay amounts in excess of an agreed threshold owing to us beyond a specified cure period.

As of December 31, 2025, we were in compliance with the credit agreement.

**NOTE 12—Employee Benefit Plans**

Substantially all of our employees participate in the NRECA Retirement Security Plan, a noncontributory, defined benefit pension plan qualified under Section 401 and tax-exempt under Section 501(a) of the IRC. It is considered a multi-employer plan under accounting standards. The legal name of the plan is the NRECA Retirement Security Plan; the employer identification number is 53–0116145, and the plan number is 333. Plan information is available publicly through the annual Form 5500, including attachments. The plan year is January 1 through December 31. In total, the NRECA Retirement Security Plan was over 80% funded on January 1, 2025 and 2024, based on the PPA funding target and PPA actuarial value of assets on those dates. The cost of the plan is funded annually by payments to NRECA to ensure that annuities in amounts established by the plan will be available to individual participants upon their retirement. There has been no funding improvement plan or rehabilitation plan implemented nor is one pending, and we did not pay a surcharge to the plan for 2025.

------

Our required contribution to the NRECA Retirement Security Plan totaled $4.3 million, $4.3 million, and $4.1 million in 2025, 2024, and 2023, respectively. In each of these years, our contributions represented less than 5% of the total contributions made to the plan by all participating employers.

Beginning in 2019, we adopted the Executive Benefit Restoration Plan, which is intended to provide a supplemental benefit for employees who would have a reduction in their pension benefit from the NRECA Retirement Security Plan because of the IRC limitations. As of December 31, 2025 and December 31, 2024, we have recorded a liability of $1.1 million and $0.6 million, respectively, in other liabilities.

Pension expense, inclusive of administrative fees, was $5.1 million, $4.7 million, and $3.6 million for 2025, 2024, and 2023, respectively. In 2023, pension expense included a credit of $1.0 million to remove the accrued benefit related to the Executive Pension Restoration Plan for our previous former President and CEO, Mr. Marcus M. Harris, which was forfeited upon his resignation in September 2023.

We have a defined contribution 401(k) retirement plan and we match up to the first 2% of each participant's base salary. Our matching contributions were $0.4 million in 2025, and $0.3 million in 2024 and 2023.

**NOTE 13—Supplemental Cash Flows Information** 

Cash paid for interest, net of amounts capitalized, in 2025, 2024, and 2023, was $47.0 million, $56.7 million, and $59.8 million, respectively. Cash paid for income taxes was immaterial in 2025, 2024, and 2023. Accrued capital expenditures in 2025, 2024, and 2023 were $24.2 million, $9.7 million, and $11.2 million, respectively.

**NOTE 14—Commitments and Contingencies**

**Environmental**

We are subject to federal, state, and local laws and regulations, and permits designed to both protect human health and the environment and to regulate the emission, discharge, or release of pollutants into the environment. We believe we are in material compliance with all current requirements of such environmental laws and regulations and permits. However, as with all electric utilities, the operation of our generating units could be affected by future changes in environmental laws and regulations, including new requirements. Capital expenditures and increased operating costs required to comply with any future regulations could be significant.

**Insurance** 

The Price-Anderson Amendments Act of 1988 provides the public up to $16.3 billion of liability protection on a per site, per nuclear incident basis, via obligations required of owners of nuclear power plants, and allows for an inflationary provision adjustment every five years. During the first quarter of 2024, the total liability protection per nuclear incident available to all participants in the secondary financial protection program increased from $16.2 billion to $16.3 billion. This increase does not impact Virginia Power or our responsibility per active unit under the Price-Anderson Amendments Act of 1988. Owners of nuclear facilities could be assessed up to $166 million for each of their licensed reactors not to exceed $25 million per year per reactor. There is no limit to the number of incidents for which this retrospective premium can be assessed. Virginia Power is responsible for operating North Anna. Under several of the nuclear insurance policies procured by Virginia Power to which we are a party, we are subject to retrospective premium assessments in any policy year in which losses exceed the funds available to the insurance companies.

As a joint owner of North Anna, we are a party to the insurance policies that Virginia Power procures to limit the risk of loss associated with a possible nuclear incident at the station, as well as policies regarding general liability and property coverage. All policies are administered by Virginia Power, which charges us for our proportionate share of the costs.

Our share of the maximum retrospective premium assessments for the coverage assessments described above is estimated to be a maximum of $41.3 million as of December 31, 2025.

**ITEM 9A. CONTROLS AND PROCEDURES**

**Evaluation of Effectiveness of Disclosure Controls and Procedures**

As of the end of the period covered by this report, our management, including the President and CEO, and the Senior Vice President and CFO, conducted an evaluation of the effectiveness of our disclosure controls and procedures. Based upon that evaluation, the President and CEO, and the Senior Vice President and CFO, concluded that our disclosure controls and procedures are effective in ensuring that all material information required to be filed in this report has been made known to them in a timely manner. We have established a disclosure assessment committee composed of members of our senior and middle management to assist in this evaluation.

**Management's Annual Report on Internal Control over Financial Reporting**

Our management has assessed our internal control over financial reporting as of December 31, 2025, based on criteria for effective internal control over financial reporting described in "2013 Internal Control – Integrated Framework" issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on this assessment, management believes that as of December 31, 2025, our system of internal control over financial reporting was properly designed and operating effectively based upon the specified criteria. We have not identified any material weaknesses in our internal control over financial reporting.

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is composed of policies, procedures, and reports designed to provide reasonable assurance to our management and board of directors that the financial reporting and the preparation of the financial statements for external reporting purposes has been handled in accordance with accounting principles generally accepted in the United States. Internal control over financial reporting includes those policies and procedures that (1) govern records to accurately and fairly reflect the transactions and dispositions of assets; (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 our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable safeguards against or timely detection of material unauthorized acquisition, use, or disposition of our assets.

**Changes in Internal Control over Financial Reporting** 

There were no material changes that occurred during the last fiscal year that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**Inherent Limitations on Internal Control**

Inherent limitations exist with respect to the effectiveness of any system of internal control over financial reporting. No control system can provide absolute assurance that all control issues and instances of error or fraud, if any, have been detected. Even the best designed system can only provide reasonable assurance that the objectives of the control system have been met. Because of these inherent limitations, our internal control over financial reporting may not prevent or detect all misstatements. Additionally, projections as to the effectiveness

------

of internal control in future periods are subject to the risk that internal control may not continue to operate at its current effectiveness levels due to changes in personnel or in our operating environment.

**ITEM 9B. OTHER INFORMATION**

During the quarter ended December 31, 2025, none of our directors or officers informed us of the adoption or termination of a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as those terms are defined in Item 408 of Regulation S-K. We have debt securities but no equity securities outstanding because we are a cooperative. See "Business—Overview" in Item 1.

**ITEM 9C. DISCLOSURE REGARDING FOREIGN JURISDICTIONS THAT PREVENT INSPECTIONS** 

Not Applicable.

**PART III**

**ITEM 10. DIRECTORS, EXECUTIVE OFFICERS AND CORPORATE GOVERNANCE**

**Directors**

We are governed by a board of 23 directors, consisting of two representatives from each of our member distribution cooperatives and one representative from TEC. Pursuant to our bylaws, each of our eleven member distribution cooperatives, in good standing, may recommend candidates that meet director qualifications to the nominating committee of our board of directors. At the annual meeting of the members, the nominating committee nominates candidates for election to our board of directors. At least one candidate from each member distribution cooperative must be a director of that member distribution cooperative. The other candidate must be either a director or employee of the member distribution cooperative. Currently and historically, this other candidate is the CEO of that member distribution cooperative. As a result, each of the candidates for director on our board has a developed understanding of the issues affecting electric cooperatives and the provision of electric services based on many years of industry experience. The candidates for director are elected to our board of directors by a majority vote of the voting delegates from our members. Each member has one voting delegate. We do not control who the member distribution cooperative recommends to the nominating committee. As a result, our board of directors has not developed criteria for the composition of our board, such as diversity, for use in identifying nominees to our board of directors. One director currently serves as a director on behalf of a member distribution cooperative and TEC. Each elected candidate is authorized to represent that member for a renewable term of one year. Our board of directors sets policy and provides direction to our President and CEO. Our board of directors meets approximately eleven times each year.

**ITEM 11. EXECUTIVE COMPENSATION**

**COMPENSATION DISCUSSION AND ANALYSIS**

**General Philosophy**

Our compensation philosophy has four objectives:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•attract and retain a qualified, diverse workforce through a competitive compensation program;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•provide equitable and fair compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•support our business strategy; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•ensure compliance with applicable laws and regulations.

**Named Executive Officers**

For fiscal year 2025, our named executive officers ("NEOs") include the following six individuals:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Christopher F. Cosby, President and Chief Executive Officer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Bryan S. Rogers, Senior Vice President and Chief Financial Officer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•John M. Robb, III, Senior Vice President and Chief Legal Officer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Andrew M. Vehorn, Senior Vice President of Member Engagement

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Michael C. Wise, Senior Vice President and Chief Operating Officer

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•John C. Lee, Jr., Former President and Chief Executive Officer

**Compensation**

**Total Compensation Package**

We compensate our President and CEO and other executive officers through the use of a total compensation package, which includes base salary, competitive benefits, and the potential of a bonus. Historically, our President and CEO's base salary is derived from salary data provided by a third party through a national compensation survey. The national compensation survey data includes data from the labor market for positions with similar responsibilities. Mr. Lee was compensated utilizing a consulting services agreement during his engagement as President and CEO.

**Targeted Overall Compensation** 

Our compensation program utilizes detailed job descriptions for all of our employees including executive officers, with the exception of the President and CEO, as an instrument to establish benchmarked positions. The market compensation information for each position is derived from salary data provided by third parties through national compensation surveys and includes salary data for positions within the determined competitive labor market. Our job descriptions are reviewed annually and include job responsibilities, required knowledge, skills and abilities, and formal education and experience necessary to accomplish the requirements of the position which in turn helps us achieve operational goals. Utilizing this information, our human resources department determines a market-based salary for each position. A third-party consultant reviews the market-based salary data we compiled for reasonableness annually. We have defined market-based salary as approximately the 50<sup>th</sup> percentile of the market. Another third-party consultant created a performance appraisal instrument for the President and CEO position.

------

**Process for Determining NEO Compensation**

We have a committee of our board of directors, the executive committee, which recommends all compensation for our President and CEO to the entire board of directors. The entire board of directors then approves the compensation arrangements for the President and CEO. Our board of directors has delegated to our President and CEO, the authority to establish and adjust compensation for all employees other than himself. The compensation for all other employees, including executive officers other than the President and CEO, is approved by our President and CEO based upon market-based salary data. On an annual basis our board of directors reviews the performance and compensation of our President and CEO, and our President and CEO reviews the performance and compensation of the remaining executive officers. Our board of directors determined the compensation payable under the consulting services agreements for our former President and CEO.

**Base Salaries**

We are an electric cooperative and do not have any stock and as a result, we do not have equity-based compensation programs. For this reason, substantially all of our compensation to our executive officers is provided in the form of base salary. We want to provide our executive officers with a level of assured cash compensation in the form of base salary that is commensurate with the duties and responsibilities of their positions. These salaries are determined based on market data for positions with similar responsibilities.

**Cash Bonuses**

Our practice has been to, on infrequent occasions, award cash bonuses related to a specific event, such as the consummation of a significant transaction. At the discretion of our board of directors, a bonus may be awarded to our President and CEO. At the discretion of our President and CEO, bonuses may be awarded to the other executive officers.

**Severance Benefits**

We believe that companies should provide reasonable severance benefits to the President and CEO. With respect to our President and CEO, these severance benefits reflect the fact that it may be difficult to find comparable employment within a short period of time. Our President and CEO's contractual rights to severance have been set forth in an employment agreement. See "Employment Agreement" below. Other than our President and CEO, none of our executive officers have any contractual severance or termination benefits other than what is provided for under the retirement plans in which they participate and any unused vacation.

**Plans**

**Retirement Plans**

We participate in the NRECA Retirement Security Plan, a noncontributory, defined benefit pension plan qualified under Section 401 and tax-exempt under Section 501(a) of the IRC. This plan is available to all employees, with limited exceptions, who work at least 1,000 hours per year. It is considered a multi-employer plan under accounting standards. Benefits, which accrue under the plan, are based upon the employee's base annual salary as of November of the previous year. During his engagement as President and CEO, Mr. Lee was not an employee of ODEC and did not participate in benefit plans available to employees.

We also have a defined contribution 401(k) retirement plan that is available to all employees in regular positions. Under the 401(k) plan for 2025, employees could elect to have up to 100% or $23,500, whichever is less, of their salary withheld on a pre-tax basis, subject to Internal Revenue Service limitations, and invested on their behalf. We match up to the first 2% of each participant's base salary. Also, there are two catch-up contribution limits available for participants in the plan. Once a participant attains age 50, there is a maximum catch-up contribution for 2025 of $7,500. Once a participant is between ages 60-63, there is a maximum catch-up contribution for 2025 of $11,250.

In addition, we have a non-qualified executive deferred compensation plan (the "Deferred Compensation Plan"). Our board of directors, at its discretion, determines who may participate in the Deferred Compensation Plan as well as an annual contribution for the benefit of our President and CEO, if any, up to the maximum amount permitted under IRC Section 457(b). Employees with the title of Vice President and above may

------

participate in this plan. We made a $23,500 contribution to the plan for the benefit of our President and CEO in 2025. See "Deferred Compensation Plan" below.

**Pension Restoration Plan**

We participate in the Executive Benefit Restoration Plan to provide a supplemental benefit for executive officers who would have a reduction in the pension benefit from the NRECA Retirement Security Plan because of IRC limitations. Our President and CEO, Senior Vice President and CFO, Senior Vice President and CLO, Senior Vice President of Member Engagement, and Senior Vice President and COO, are currently the only participants in this plan.

**Perquisites and Other Benefits**

Our board of directors reviews the perquisites that our President and CEO receives during contract discussions. Mr. Lee, our former President and CEO, in accordance with his consulting services agreement, was provided temporary housing and a monthly automobile allowance of $1,500 during 2025. Beginning in February 2025, Mr. Cosby, our President and CEO, received a monthly automobile allowance of $1,500 in accordance with his employment contract.

The executive officers, other than Mr. Lee, participate in our other benefit plans on the same terms as other employees. These plans include the defined benefit pension plan, the 401(k) plan, medical insurance, life insurance and accidental death and dismemberment, long-term disability, medical reimbursement and dependent care flexible spending accounts, health savings account, fitness facility membership, vacation, holiday, and sick leave. Relocation benefits are reimbursed for all employees who transfer to another location at the request or convenience of ODEC in accordance with our relocation policy. We believe these benefits are customary for similar employers.

**Change in Control**

We have no arrangements with any other NEOs that increase or decrease any amounts payable to him as a result of a change in control.

------

The following table sets forth information concerning compensation awarded to, earned by or paid to our NEOs for services rendered to us in all capacities during each of the last three fiscal years. The table also identifies the principal capacity in which each of these executives served.

<sup>(1)</sup> For Mr. Cosby, includes automobile allowance.

<sup>(2)</sup> Mr. Lee did not participate in any ODEC employee benefit plans. Perquisites includes temporary housing of $5,022 and an automobile allowance of $18,000.

**Potential Payments upon Termination or Change in Control** 

Except for Mr. Cosby, our current President and CEO, and Mr. Lee, our former President and CEO and current Senior Advisor to ODEC, none of our NEOs have any contractual termination benefits other than as provided under the retirement plans in which they participate and none of our NEOs have any change in control benefits.

In accordance with his consulting services agreement, as amended, Mr. Lee received a monthly compensation of $125,000 and a monthly automobile allowance of $1,500 until December 31, 2025.

**Employment Agreement** 

Except for our current President and CEO, we do not have employment agreements with our NEOs or Vice President and Controller.

On December 10, 2024, ODEC entered into a three year employment agreement with Christopher F. Cosby, our President and CEO as of February 1, 2025, with an effective date of February 1, 2025. The agreement provides that he will receive an annual base salary of $1,150,000, effective as of February 1, 2025. Salary increases shall be considered at each year end and may be awarded at the discretion of the board of directors. In addition to his annual compensation, Mr. Cosby is eligible to participate in the Deferred Compensation Plan. The employment agreement also provides for a $1,500 monthly automobile allowance. Mr. Cosby is also entitled to participate in all benefit plans available to the employees of ODEC.

Under the agreement, during the contract term, if Mr. Cosby voluntarily terminates his employment following material breach by us or we terminate his employment without specified cause, we will pay Mr. Cosby compensation at the rate in effect on the date of termination for one additional year from the date of termination, plus medical insurance benefits for one year, with limited exceptions. In addition, Mr. Cosby is entitled to receive any benefits that he otherwise would have been entitled to receive including benefits under our 401(k) plan, pension plan, and supplemental retirement plans, although those benefits will not be increased or accelerated, and any unused vacation.

------

However, if Mr. Cosby becomes employed in any capacity during the one-year period immediately following the date of termination, ODEC's obligation to pay Mr. Cosby's salary at the rate in effect on the date of termination shall be reduced by the amount of his salary that he receives from his new employer. Also, the medical insurance benefits will cease if he becomes eligible for medical insurance coverage by virtue of his employment with another company.

Based upon a hypothetical termination date of December 31, 2025, under Mr. Cosby's employment contract as President and CEO, in addition to any benefits that he otherwise would have been entitled to receive including benefits under our 401(k) plan, pension plan, supplemental retirement plans, and any unused vacation, Mr. Cosby would have been entitled to receive the following:

---

| | |
|:---|:---|
| Cash severance | $1150000 |
| Medical Insurance | 29997 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total | $1179997 |

---

Under our employment contract with Mr. Cosby "cause" is defined as (1) gross incompetence, insubordination, gross negligence, willful misconduct in office or breach of a material fiduciary duty, which includes a breach of confidentiality; (2) conviction of a felony, a crime of moral turpitude or commission of an act of embezzlement or fraud against ODEC or any subsidiary or affiliate thereof; (3) the President and CEO's material failure to perform a substantial portion of his duties and responsibilities under the employment contract, but only after ODEC provides the President and CEO written notice of such failure and gives him 30 days to remedy the situation; (4) deliberate dishonesty of the President and CEO with respect to ODEC or any of its subsidiaries or affiliates; or (5) a violation of one of ODEC's written policies which, if curable, is not cured within 30 days after written notice of such violation is provided to the President and CEO, or such violation reoccurs after written notice and an opportunity to cure has been provided.

The President and CEO may terminate his employment with or without good reason by written notice to the board of directors effective 60 days after receipt of such notice by the board of directors. If the President and CEO terminates his employment for good reason, then the President and CEO is entitled to the salary specified above in the "without cause" paragraph. The President and CEO will not be required to render any further services. Upon termination of employment by the President and CEO without good reason, the President and CEO is not entitled to further compensation. Under our employment contract with Mr. Cosby, "good reason" is defined as ODEC's failure to maintain compensation or ODEC's material breach of any provision of the employment contract, which failure or breach continued for more than 30 days after the date on which the board of directors received such notice.

**Other Executive Officers**

Based upon a hypothetical termination date of December 31, 2025, Mr. Rogers, Mr. Robb, Mr. Vehorn, and Mr. Wise would only be entitled to the benefits accrued under the retirement plans in which they participate, and any unused vacation. See "Plans" above and "Defined Benefit Plans" below for more information as to the benefits that would be paid under the retirement plans in which they participate. Mr. Lee did not participate in any of these plans.

**Defined Benefit Plans**

The following table lists the estimated values under the NRECA Retirement Security Plan and the Executive Benefit Restoration Plan as of December 31, 2025. As a result of changes in Internal Revenue Service

------

regulations, the base annual salary used in determining benefits was limited to $350,000, effective January 1, 2025.

<sup>(1)</sup> Numerical amounts in this table were computed as of December 31, 2025, and the present value amounts were determined using the same assumptions used for financial reporting purposes.

<sup>(2)</sup> Mr. Vehorn became an executive officer in December 2024. Mr. Vehorn participated in the NRECA Retirement Security Plan with a former employer and earned 8.50 years of credited service with his former employer and began earning years of credited service as an ODEC employee beginning in 2025.

<sup>(3)</sup> Mr. Lee resigned as President and CEO of ODEC effective February 1, 2025, and served as Senior Advisor from February 1, 2025 to December 31, 2025. He served as President and CEO of ODEC from February 6, 2024 to February 1, 2025; and served as Interim President and CEO of ODEC, from September 8, 2023, to February 5, 2024. Mr. Lee was an independent contractor of ODEC and was not eligible to participate in any benefit plans available to employees of ODEC.

The pension benefits indicated above are the estimated amounts payable by the plan, and they are not subject to any deduction for social security or other offset amounts. For employees hired before January 1, 2022, the participant's annual pension at his or her normal retirement date, currently age 62 under the plan, is equal to the product of his or her years of benefit service times final average salary times the multiplier in effect during years of benefit service, and the multiplier was 1.7% commencing January 1, 1992. For employees hired on or after January 1, 2022, the participant's annual pension at his or her normal retirement date, currently age 65 under the plan, is equal to the product of his or her years of benefit service times final average salary times the multiplier in effect during years of benefit service, and the multiplier was 1.5% commencing January 1, 2022. The number of years of credited service is as of the end of the current year for each of the named executives. The present value of accumulated benefit is calculated assuming that the executive retires at the normal retirement age per the plan, but using current number of years of credited service, and that he or she receives a lump sum. The lump sum amounts are calculated using the 30-year Treasury rate (4.04% for 2025) and the PPA three segment yield rates (4.17%, 4.76%, and 5.25% for 2025) and the required Internal Revenue Service mortality table for lump sum payments (Group Annuity Reserving 1994, projected to 2002, blended 50%/50% for unisex mortality in combination with the 30-year Treasury rates and PPA Retirement Plan 2000 at 2025 combined unisex 50%/50% mortality in combination with the PPA rates). Lump sums at normal retirement age are then discounted to the last day of the appropriate year using these same assumptions shown for the respective stated interest rates.

------

The Executive Benefit Restoration Plan is intended to provide a supplemental benefit for employees who would have had a reduction in their pension benefit because of IRC limitations.

**Deferred Compensation Plan**

In 2006, we adopted the Deferred Compensation Plan, a non-qualified plan, for the purposes of allowing participants to defer their compensation and providing supplemental deferred compensation within the statutory maximums permitted under IRC Section 457(b). Our board of directors determined that, beginning in 2019, employees with the title of Vice President and above may participate in this plan. In 2025, Mr. Cosby and Mr. Rogers were the only NEOs who participated in the plan. Under the Deferred Compensation Plan, annual deferrals cannot exceed the lesser of 100% of a participant's annual compensation or $23,500 for 2025, adjusted by and subject to specified tax laws, during any year in which we are exempt from federal income taxation. Amounts credited to the participants under the Deferred Compensation Plan will be credited with earnings or losses equal to those made by an investment in one or more funds of a specified regulated investment company designated by the participant.

The following table sets forth the non-qualified deferred compensation paid to our NEOs in 2025:

**Board of Directors Compensation** 

It is our policy to compensate the members of our board of directors who are not employed by one of our member distribution cooperatives ("outside directors"). During 2025, our outside directors were compensated with a monthly retainer of $4,200 and beginning January 1, 2026, they are compensated with a monthly retainer of $4,500. They were also paid for meetings and other official activities at a per diem rate of $700 per full day and $350 per partial day and for teleconferences, if such meetings or other official activities occurred outside the normal board of directors meeting dates. Our directors receive no other compensation from us. We do not provide our directors pension benefits, non-equity incentive plan compensation, or other perquisites and because

------

we are a cooperative, we do not have stock or other equity options. The following table sets forth the compensation we paid to our outside directors in 2025:

**Compensation Committee Interlocks and Insider Participation**

As described above, the executive committee of our board of directors establishes and the full board of directors approves all compensation and awards paid to our President and CEO. Our board of directors has delegated to our President and CEO, the authority to establish and adjust compensation for all employees other than himself. Other than the exception noted below, no member of our board of directors is or previously was an officer or employee of ODEC or is or has engaged in transactions with ODEC. Mr. John C. Lee, Jr. was an employee of ODEC from 1992 to 2007 when he left his position as Vice President of Member and External Relations to become the President and CEO of Mecklenburg Electric Cooperative, one of our member distribution cooperatives. Mr. Lee served as ODEC's Interim President and CEO from September 2023 to February 6, 2024, when he was appointed ODEC's President and CEO. Mr. Lee resigned as President and CEO of ODEC effective February 1, 2025. All of our directors are employees or directors of our member distribution cooperatives.

Under our executive committee charter, the executive committee's duties and responsibilities include (1) recommending all compensation for ODEC's President and CEO to the board of directors for its approval and (2) serving as the compensation committee of the board of directors to review and discuss with management the contents of the Compensation Discussion and Analysis section of the Annual Report on Form 10-K and to recommend to the board of directors inclusion of the Compensation Discussion and Analysis section in the Annual Report on Form 10-K each year.

**CEO Pay Ratio** 

The annual total compensation of Mr. Cosby, our President and CEO, for 2025 was $1,275,917. Based on reasonable estimates, the median annual total compensation of all of our employees, excluding our President and CEO, was $291,677 for 2025. Accordingly, for 2025, the ratio of the total compensation of our President and CEO to the median of the annual total compensation of all of our other employees was 4.4 to 1.

We identified our median employee based on salary earned in 2025 by each individual who was employed by us on November 15, 2025. We annualized the salary of all permanent employees who were not employed through the entire year.

------

**Compensation Committee Report**

The executive committee serves as the compensation committee of the board of directors and has reviewed and discussed with the management of ODEC the contents of the Compensation Discussion and Analysis section and, based on such review and discussion, has recommended to the board of directors its inclusion in this Annual Report on Form 10-K.

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

Not Applicable.

**ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE**

Because we are a cooperative, all of our directors are representatives of our members. Our members include our member distribution cooperatives, which are our principal customers, and TEC. Due to the extent of the payments by each member distribution cooperative to us, our directors are not independent based on the definition of "independence" of the New York Stock Exchange listing standards.

There are no related person transactions in 2025 that the SEC would require to be reported under its rules. In accordance with our code of ethics, all directors are prohibited from participating in any activity or association that creates or appears to create a conflict between their personal interest and our business interests unless approved after full and fair disclosure of the relevant facts. Directors must obtain approval from the board of directors for any such transactions.

**ITEM 14. PRINCIPAL ACCOUNTANT FEES AND SERVICES**

Ernst & Young LLP served as our independent registered public accounting firm during 2025. The following table presents fees for services provided by Ernst & Young LLP for the two most recent fiscal years. All Audit, Audit-Related, and Tax Fees shown below were pre-approved by the audit committee in accordance with its established procedures.

**Audit Committee Preapproval Process for the Engagement of Auditors**

All audit, tax, and other services to be performed by Ernst & Young LLP for us must be pre-approved by the audit committee. The audit committee reviews the description of the services and an estimate of the anticipated costs of performing those services. Pre-approval is granted usually at regularly scheduled meetings. During 2025 and 2024, all services performed by Ernst & Young LLP were pre-approved by the audit committee in accordance with this policy.

**Section 2.4** **<u>Optional Redemption at Par</u>**. The 2025 Series A Bonds are subject to redemption at the Company's option, in whole and not in part, within 90 days prior to the final maturity of the 2025 Series A Bonds at a Redemption Price equal to 100% of the principal amount, together with accrued interest to the Redemption Date. From and after such Redemption Date, interest on such principal amount being redeemed shall cease to accrue.

Upon receipt of a notice from the Company of its intent to effect an optional redemption of the 2025 Series A Bonds pursuant to this Section, the Trustee shall cause written notice of such redemption to be given to each 2025 Series A Holder of the 2025 Series A Bonds then Outstanding not less than 30 days and not more than 60 days prior to the Redemption Date. The notice of redemption shall specify the Redemption Date, that interest, if any accrued to the Redemption Date will be paid as specified in such notice and that on and after such date interest thereon shall cease to accrue. Any 2025 Series A Bond redeemed in full shall be surrendered to the Company reasonably promptly after payment is made in full in accordance with Section 11 of the Bond Purchase Agreement and cancelled and shall not be reissued, and no 2025 Series A Bond shall be issued in lieu of any redeemed principal amount of any such cancelled 2025 Series A Bond.

**Section 2.5** **<u>Optional Redemption With Make-Whole Amount.</u>** The Company may, at its option, upon notice as provided below, redeem at any time all, or from time to time any part of, the 2025 Series A Bonds in an amount not less than 3% of the aggregate principal amount of the 2025 Series A Bonds then outstanding in the case of a partial redemption, at 100% of the principal amount so redeemed, and the Make-Whole Amount determined for the redemption date with respect to such principal amount. The Company will give each 2025 Series A Holder written notice of each optional redemption under this Section 2.5 not less than 30 days and not more than 60 days prior to the date fixed for such redemption. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the 2025 Series A Bonds to be redeemed on such date, the principal amount of each 2025 Series A Bond held by such 2025 Series A Holder to be redeemed (determined in accordance with Section 2.6 herein), and the interest to be paid on the redemption date with respect to such principal amount being redeemed, and shall

------

be accompanied by an Officer's Certificate as to the estimated Make-Whole Amount due in connection with such redemption (calculated as if the date of such notice were the date of the redemption), setting forth the details of such computation. Two Business Days prior to the date fixed for such redemption, the Company shall deliver to each 2025 Series A Holder an Officer's Certificate specifying the calculation of such Make-Whole Amount as of the specified redemption date. The Company shall contemporaneously deliver a copy of such notice and Officer's Certificate to the Trustee.

**Section 2.6** **<u>Allocation of Partial Redemptions.</u>** In the case of each partial redemption of the 2025 Series A Bonds pursuant to Section 2.3 or 2.5 hereof, the principal amount of the 2025 Series A Bonds to be redeemed shall be allocated among all of the 2025 Series A Bonds at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for redemption.

**Section 2.7** **<u>Payment of Make-Whole Amount Upon Acceleration.</u>** Upon the occurrence of an Event of Default, if the outstanding principal amount of the 2025 Series A Bonds shall have been declared or otherwise become due and payable immediately pursuant to and in accordance with the Indenture then, in addition to paying each 2025 Series A Holder the entire unpaid principal amount of its 2025 Series A Bonds and all accrued and unpaid interest thereon (including, but not limited to, interest accrued thereon at the applicable Default Rate), the Company shall calculate and pay to each 2025 Series A Holder (to the full extent permitted by applicable law) an amount equal to the Make-Whole Amount determined in respect of such principal amount. The Company acknowledges that each 2025 Series A Holder has the right to maintain its investment in the 2025 Series A Bonds free from repayment by the Company (except as herein and in the Indenture specifically provided for), and that the provision for payment of a Make-Whole Amount by the Company in the event that the 2025 Series A Bonds are redeemed or are accelerated as a result of an Event of Default is intended to provide compensation for the deprivation of such right under such circumstances.

**Section 2.8** **<u>Maturity; Surrender; Etc.</u>** In the case of each redemption of 2025 Series A Bonds pursuant to this Article 2, the principal amount of each 2025 Series A Bond to be redeemed shall mature and become due and payable on the date fixed for such redemption (which shall be a Business Day), together with interest on such principal amount accrued to such date and the applicable Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any 2025 Series A Bond redeemed in full shall be surrendered to the Company and cancelled and shall not be reissued, and no 2025 Series A Bond shall be issued in lieu of any redeemed principal amount of any such cancelled 2025 Series A Bond.

**Section 2.9** **<u>Purchase of 2025 Series A Bonds</u>.** The Company will not, and will not permit any Affiliate to, purchase, redeem, prepay or otherwise acquire, directly or indirectly, any of the outstanding 2025 Series A Bonds except (a) upon the payment, redemption or prepayment of the 2025 Series A Bonds in accordance with the terms of the Original Indenture and the 2025 Series A Bonds or (b) pursuant to an offer to purchase made by the Company or an Affiliate *pro rata* to the 2025 Series A Holders of all 2025 Series A Bonds at the time outstanding upon the same terms and conditions. Any such offer shall provide each 2025 Series A Holder with sufficient

------

information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 30 Business Days. If the 2025 Series A Holders of more than 51% of the principal amount of the 2025 Series A Bonds then outstanding accept such offer, the Company shall promptly notify the remaining 2025 Series A Holders of such fact and the expiration date for the acceptance by 2025 Series A Holders of such offer shall be extended by the number of days necessary to give each such remaining 2025 Series A Holder at least 10 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all 2025 Series A Bonds acquired by it or any Affiliate pursuant to any payment, redemption, prepayment or purchase of 2025 Series A Bonds pursuant to any provision of this Fifth Supplemental Indenture and no 2025 Series A Bonds may be issued in substitution or exchange for any such 2025 Series A Bonds.

**Section 2.10** **<u>Make-Whole Amount.</u>**

*"Make-Whole Amount"* means, with respect to any 2025 Series A Bond, an amount equal to the excess, if any, of the Discounted Value of the Remaining Scheduled Payments with respect to the Called Principal of such 2025 Series A Bond over the amount of such Called Principal, *provided* that the Make-Whole Amount may in no event be less than zero. For the purposes of determining the Make-Whole Amount with respect to any 2025 Series A Bond the following terms have the following meanings:

*"Called Principal"* means, with respect to any 2025 Series A Bond, the principal of such 2025 Series A Bond that is to be redeemed pursuant to Section 2.5 hereof or has become or is declared to be immediately due and payable pursuant to the Indenture, as the context requires.

*"Discounted Value"* means, with respect to the Called Principal of any 2025 Series A Bond, the amount obtained by discounting all Remaining Scheduled Payments with respect to such Called Principal from their respective scheduled due dates to the Settlement Date with respect to such Called Principal, in accordance with accepted financial practice and at a discount factor (applied on the same periodic basis as that on which interest on the 2025 Series A Bonds is payable) equal to the Reinvestment Yield with respect to such Called Principal.

*"Reinvestment Yield"* means, with respect to the Called Principal of any 2025 Series A Bond, the sum of 0.50% plus the yield to maturity implied by the yields reported as of 10:00 A.M. (New York City time) on the second Business Day preceding the Settlement Date with respect to such Called Principal, on the display designated as "Page PX1" (or such other display as may replace Page PX1) on Bloomberg Financial Markets for the most recently issued actively traded on-the-run U.S. Treasury securities ("*Reported*") having a maturity equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there are no such U.S. Treasury securities Reported having a maturity equal to such Remaining Average Life, then such implied yield to maturity will be determined by (a) converting U.S. Treasury bill quotations to bond equivalent yields in accordance with accepted financial practice and (b) interpolating linearly between the yields Reported for the applicable most recently issued actively traded on-the-run U.S. Treasury securities with the maturities (1) closest to and greater than such Remaining Average Life and (2) closest to and less than such Remaining Average Life. The Reinvestment Yield shall

------

be rounded to the number of decimal places as appears in the interest rate of the 2025 Series A Bond.

If such yields are not Reported or the yields Reported as of such time are not ascertainable (including by way of interpolation), then "Reinvestment Yield" means, with respect to the Called Principal of any 2025 Series A Bond, 0.50% over the yield to maturity implied by the U.S. Treasury constant maturity yields reported, for the latest day for which such yields have been so reported as of the second Business Day preceding the Settlement Date with respect to such Called Principal, in Federal Reserve Statistical Release H.15 (or any comparable successor publication) for the U.S. Treasury constant maturity having a term equal to the Remaining Average Life of such Called Principal as of such Settlement Date. If there is no such U.S. Treasury constant maturity having a term equal to such Remaining Average Life, such implied yield to maturity will be determined by interpolating linearly between (1) the U.S. Treasury constant maturity so reported with the term closest to and greater than such Remaining Average Life and (2) the U.S. Treasury constant maturity so reported with the term closest to and less than such Remaining Average Life. The Reinvestment Yield shall be rounded to the number of decimal places as appears in the interest rate of the 2025 Series A Bond.

*"Remaining Average Life"* means, with respect to any Called Principal, the number of years obtained by dividing (i) such Called Principal into (ii) the sum of the products obtained by multiplying (a) the principal component of each Remaining Scheduled Payment with respect to such Called Principal by (b) the number of years, computed on the basis of a 360-day year composed of twelve 30-day months and calculated to two decimal places, that will elapse between the Settlement Date with respect to such Called Principal and the scheduled due date of such Remaining Scheduled Payment.

*"Remaining Scheduled Payments"* means, with respect to the Called Principal of any 2025 Series A Bond, all payments of such Called Principal and interest thereon that would be due after the Settlement Date with respect to such Called Principal if no payment of such Called Principal were made prior to its scheduled due date; *provided* that if such Settlement Date is not a date on which interest payments are due to be made under the terms of the 2025 Series A Bonds, then the amount of the next succeeding scheduled interest payment will be reduced by the amount of interest accrued to such Settlement Date and required to be paid on such Settlement Date pursuant to Section 2.5 or Section 2.7 above.

*"Settlement Date"* means, with respect to the Called Principal of any 2025 Series A Bond, the date on which such Called Principal is to be redeemed pursuant to Section 2.5 above or has become or is declared to be immediately due and payable pursuant to the Indenture, as the context requires.

**Section 2.11** **<u>Use of Proceeds.</u>** The Company shall use the proceeds of the loan evidenced by the 2025 Series A Bonds for the repayment of indebtedness and general corporate purposes.

------

**ARTICLE III** **<br>Outstanding Secured Obligations**

**Section 3.1** **<u>Principal Amount Presently to Be Outstanding.</u>** The total aggregate principal amount of Obligations of the Company issued and Outstanding on the date hereof prior to any principal payments on such date and presently to be issued and Outstanding under the provisions of and secured by the Indenture is One Billion One Hundred Seventy-Seven Million Nine Hundred Fourteen Thousand Dollars ($1,177,914,000.00) consisting of: Fifty Million Dollars ($50,000,000.00) principal amount of First Mortgage Bonds, 2002 Series B; Forty-One Million Six Hundred Sixty-Four Thousand Dollars ($41,664,000.00) principal amount of First Mortgage Bonds, 2003 Series A; Forty-Eight Million Dollars ($48,000,000.00) principal amount of First Mortgage Bonds, 2011 Series A; One Hundred Thirty-Two Million Dollars ($132,000,000.00) principal amount of First Mortgage Bonds, 2011 Series B; Sixty-One Million Seven Hundred Fifty Thousand Dollars ($61,750,000.00) principal amount of First Mortgage Bonds, 2011 Series C; Fifty Million Dollars ($50,000,000.00) principal amount of First Mortgage Bonds, 2013 Series A; Fifty Million Dollars ($50,000,000.00) principal amount of First Mortgage Bonds, 2013 Series B; Two Hundred Sixty Million Dollars ($260,000,000.00) principal amount of First Mortgage Bonds, 2015 Series A; Seventy-Two Million Dollars ($72,000,000.00) principal amount of First Mortgage Bonds, 2015 Series B; One Hundred Sixty-Two Million Five Hundred Thousand Dollars ($162,500,000) principal amount of First Mortgage Bonds, 2017 Series A; and Two Hundred Fifty Million Dollars ($250,000,000.00) principal amount of First Mortgage Bonds, 2025 Series A to be issued pursuant to this Fifth Supplemental Indenture upon compliance by the Company with the provisions of the Indenture.

**EXHIBIT A**

**FORM OF 2025 Series A BONDS**

**THIS 2025 SERIES A BOND HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND MAY NOT BE SOLD OR OTHERWISE TRANSFERRED IN THE ABSENCE OF SUCH REGISTRATION OR AN APPLICABLE EXEMPTION THEREFROM EXCEPT UNDER CIRCUMSTANCES WHERE NEITHER SUCH REGISTRATION NOR SUCH EXEMPTION IS REQUIRED BY LAW.** 

**OLD DOMINION ELECTRIC COOPERATIVE** 

**FIRST MORTGAGE Bonds, 2025 Series A due December 1, 2052**

**<br>NO. [_______] iSSUANCE DATE: [_________]<br>$[__________] PPN: [_____]<br>**

<br> FOR VALUE RECEIVED, the undersigned, OLD DOMINION ELECTRIC COOPERATIVE (herein called the *"Company"*), a Virginia utility aggregation cooperative, hereby promises to pay to [_____], or registered assigns, the principal sum of [_____] Dollars (or so much thereof as shall not have been prepaid) on December 1, 2052, with interest computed on the basis of a 360-day year of twelve 30-day months (a) on the unpaid balance hereof at a rate of 5.37% per annum (plus, upon the occurrence and during the continuation of an Interest Rate Adjustment Event (as hereinafter defined), an additional 2.00% per annum) from the earlier of the date hereof or the most recent Interest Payment Date to which interest has been paid or duly provided for, payable semi-annually on the 1st day of June and December, commencing on June 1, 2026, until the principal hereof shall have become due and payable, and (b) to the extent permitted by law, on any overdue payment (including any overdue prepayment) of principal, any overdue payment of interest, any overdue payment of any Make-Whole Amount (as defined in the Fifth Supplemental Indenture referred to below), payable semiannually as aforesaid (or, at the option of the registered Holder hereof, on demand), at the Default Rate (as defined in the Fifth Supplemental Indenture referred to below). Immediately upon the cessation or waiver of an Interest Rate Adjustment Event this Bond shall cease to bear the additional 2.00% per annum interest rate referenced in clause (a) above.

*"Interest Rate Adjustment Event"* means the occurrence of any of the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) the Company defaults in the performance of Section 7.1(a) or (b) or Section 7.2 of the Bond Purchase Agreement (as defined below); or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) any representation or warranty made in writing by or on behalf of the Company or by any officer of the Company in the Bond Purchase Agreement (as defined below) or in any writing furnished in connection with the transactions

------

contemplated by the Fifth Supplemental Indenture (referred to below) proves to have been false or incorrect in any material respect on the date as of which made and, with respect to representations and warranties made after the date hereof, for which accurate information has not since been provided in writing to the Holder of this Bond;

*provided*, that, in either case, an Interest Rate Adjustment Event shall not be deemed to have occurred or be continuing with respect to any portion of the 2025 Series A Bonds for which the Default Rate is then applicable.

Subject to Section 11 of the Bond Purchase Agreement (defined below), payments of principal of, interest on, and any Make-Whole Amount with respect to this Bond are to be made in lawful money of the United States of America in accordance with the terms of the Indenture.

This Bond is one of the 2025 Series A Bonds (herein called the *"Bonds"*) issued pursuant to the Fifth Supplemental Indenture, dated as of December 1, 2025 (as from time to time amended, the *"Fifth Supplemental Indenture"*), between the Company and the Trustee named therein which amends and supplements the Second Amended and Restated Indenture of Mortgage and Deed of Trust, dated as of January 1, 2011 (as amended and supplemented from time to time, the *"Indenture"*), and is entitled to the benefits thereof and the Bond Purchase Agreement dated as of December 16, 2025, between the Company and the purchasers listed in Schedule A thereto (the *"Bond Purchase Agreement"*). Each Holder of this Bond will be deemed, by its acceptance hereof, to have (i) agreed to the confidentiality provisions set forth in Section 18 of the Bond Purchase Agreement and (ii) made the representations set forth in Section 6 of the Bond Purchase Agreement. Unless otherwise indicated, capitalized terms used in this Bond shall have the respective meanings ascribed to such terms in the Fifth Supplemental Indenture.

This Bond shall be registered in the name of the Holder hereof. This Bond is transferable, as provided in the Indenture, only upon the registration books of the Company maintained by the Obligation Registrar, which shall be the Trustee, kept at its principal office, upon presentation at said office of this Bond with the written request of the registered owner hereof or his attorney duly authorized in writing, and a written instrument of transfer satisfactory to the Obligation Registrar duly executed by the registered owner or his duly authorized attorney.

The Bonds shall be issued as fully registered Bonds without coupons and in minimum denominations of $1.00 and any integral multiple of $1.00 in excess thereof. The Trustee may impose a charge sufficient to reimburse the Company or the Trustee for any tax, fee or other governmental charge required to be paid with respect to such exchange or any transfer of a Bond. The cost, if any, of preparing each new Bond issued upon such exchange or transfer, and any other expenses of the Company or the Trustee incurred in connection therewith, shall be paid by in accordance with Section 3.06 of the Indenture.

The Company will make mandatory redemptions of principal on the dates and in the amounts specified in the Fifth Supplemental Indenture. This Bond is also subject to optional redemption and may be the subject of an offer to purchase at the times and on the terms specified in the Fifth Supplemental Indenture, but not otherwise.

------

If an Event of Default under the Indenture occurs and is continuing, the principal of this Bond may be declared or otherwise become due and payable in the manner, at the price (including any applicable Make-Whole Amount) and with the effect provided in the Indenture. In the event that the principal of this Bond shall have been declared or otherwise become due and payable as described in the preceding sentence, then, in addition to paying the Holder hereof the entire unpaid principal amount of this Bond and all accrued and unpaid interest hereon (including, but not limited to, interest accrued hereon at the Default Rate), the Company shall pay to the Holder hereof (to the full extent permitted by applicable law) an amount equal to the Make-Whole Amount determined in respect of such principal amount.

The Holder of this Bond shall have no right to enforce the provisions of the Indenture, or to institute action to enforce the covenants therein, or to take any action with respect to any default under the Indenture, or to institute, appear in or defend any suit or other proceeding with respect thereto, except as provided in the Indenture and the Bond Purchase Agreement.

All acts and proceedings required by law and by the Articles of Incorporation and Bylaws of the Company necessary to make the 2025 Series A Bonds issued under the Indenture, when executed by the Company, authenticated and delivered by the Trustee and duly issued, the valid, binding and legal obligations of the Company, in accordance with its terms, have been done and taken.

It is the intention of the Holder to comply with the usury laws of the Commonwealth of Virginia and of the United States of America. This Bond is hereby expressly limited such that in no contingency or event whatsoever, whether by reason of acceleration, prepayment, or otherwise, shall the amount of interest contracted for, charged or received by the Holder for the use, forbearance, or detention of the principal indebtedness or interest hereof, which remains unpaid from time to time, exceed the highest maximum rate permitted by applicable law. If fulfillment of any provisions hereof, at the time of performance of such provisions shall be due, shall involve transcending the valid limits prescribed by applicable law, then, ipso facto, the obligation to be fulfilled shall be reduced to the maximum rate allowed by applicable law. If any Holder receives as interest an amount which will exceed the maximum rate allowed by applicable law, such amount shall be applied to the reduction of the principal amount owing hereunder or on account of any other principal indebtedness owed to Holder and not to the payment of interest, or if such excessive interest exceeds the unpaid balance of principal hereof and such other indebtedness, such excess shall be refunded. To the extent not prohibited by applicable law, determination of the maximum rate allowed by applicable law shall at all times be made by amortizing, prorating, allocating and spreading in equal parts during the full term of this Bond, all interest at any time contracted for, charged or received from the Company in connection with this Bond, so that the actual rate of interest on account of such indebtedness is uniform throughout the term of this Bond. The terms of this paragraph shall control and supersede any other provisions of this Bond.

This Bond shall be construed in accordance with and governed by the law of the Commonwealth of Virginia.

No covenant or agreement contained in this Bond, the Indenture or the Fifth Supplemental Indenture shall be deemed to be a covenant or agreement of any official, officer, agent or employee of the Company in his individual capacity, and no officer of the Company executing this Bond shall be liable personally on this Bond or be subject to any personal liability or accountability by

------

reason of the issuance of this Bond.

This Bond shall not be entitled to any benefit under the Indenture or be valid until this Bond shall have been authenticated by the execution by the Trustee, or its successor as Trustee, of the Certificate of Authentication inscribed hereon.

## Exhibit 31.1

**Exhibit 31.1**

**CERTIFICATIONS**

I, Christopher F. Cosby, certify that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. I have reviewed this annual report on Form 10-K of Old Dominion Electric Cooperative;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Based on my knowledge, this annual report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this annual report;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Based on my knowledge, the financial statements, and other financial information included in this annual report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this annual report;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The registrant's other certifying officer and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and we have:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a) designed such disclosure controls and procedures or caused such disclosure controls to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in which this annual report is being prepared;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b) designed such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, 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;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(c) evaluated the effectiveness of the registrant's disclosure controls and procedures and presented in this report our conclusions about the effectiveness of the disclosure controls and procedures as of the end of the period covered by this report based on such evaluation; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d) disclosed in this report any change in the registrant's internal control over financial reporting that occurred during the registrant's most recent fiscal quarter (the registrant's fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect the registrant's internal control over financial reporting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.
