**FORWARD-LOOKING INFORMATION**

This Quarterly Report contains forward-looking statements relating to future events and future performance. All statements other than those that are purely historical may be forward-looking statements. In certain cases, forward-looking statements can be identified by the use of words such as "may," "will," "should," "expect," "anticipate," "believe," "intend," "project," "plan," "predict," "assume," "forecast," "estimate," "objective," "possible," "probably," "likely," "potential," "speculate," "aim," "aspiration," "goal," "seek," "strategy," "target," the negative of such words, or other similar expressions.

Although the Tennessee Valley Authority ("TVA") believes that the assumptions underlying any forward-looking statements are reasonable, TVA does not guarantee the accuracy of these statements. Numerous factors could cause actual results to differ materially from those in any forward-looking statements. These factors include, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Significant additional costs for TVA to manage and operate its coal combustion residuals ("CCR") facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The cost of complying with known, anticipated, or new environmental requirements, some of which could render continued operation of many of TVA's aging coal-fired generation units not cost-effective or result in their removal from service, perhaps permanently;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Federal legislation aimed specifically at curtailing TVA's activities, including legislation that may require the divestiture of TVA or the sale of certain of TVA's assets; restrict access to its United States Department of the Treasury ("U.S. Treasury") account; eliminate its sole authority to set rates; restrict its authority to manage the Tennessee River system; lower the debt ceiling on bonds, notes, or other evidences of indebtedness (collectively, "Bonds") specified in the Tennessee Valley Authority Act of 1933, as amended ("TVA Act"); or limit its ability to pay its Chief Executive Officer or other employees competitive salaries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• New, existing, or amended laws, regulations, executive orders ("EOs"), or administrative orders or interpretations, including those related to climate change and other environmental matters, and the costs of complying with these laws, regulations, EOs, or administrative orders or interpretations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Loss of TVA's protected service territory if the Federal Energy Regulatory Commission ("FERC") were to limit the application of the anti-cherrypicking provision, or if Congress were to eliminate the anti-cherrypicking provision, without corresponding legislative modifications to the territorial limitations imposed by the fence;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Additional federal reliability standards set forth by the North American Electric Reliability Corporation ("NERC") and approved by FERC and the costs of complying with these new standards;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The failure of TVA's generation, transmission, navigation, flood control, and related assets and infrastructure, including CCR facilities, dams, and spent nuclear fuel storage facilities, to operate as anticipated, resulting in health, safety, or environmental problems, lost revenues, damages, or other costs that are not reflected in TVA's financial statements or projections, including due to aging, technological issues, or extreme weather conditions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Significant delays and additional costs, public opposition, and/or inability to obtain necessary regulatory approvals, licenses, or permits, for major projects, including for assets that TVA needs to serve its existing and future load and to meet its carbon reduction aspirations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Risks associated with the operation of nuclear facilities or other generation and related facilities, including CCR facilities and dams;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Events at a nuclear facility, whether or not operated by or licensed to TVA, which, among other things, could lead to increased regulation or restriction on the construction, ownership, operation, or decommissioning of nuclear facilities or on the storage of spent fuel, obligate TVA to pay retrospective insurance premiums, reduce the availability and affordability of insurance, increase the costs of operating TVA's existing nuclear units, or cause TVA to forego future construction at these or other facilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The inaccuracy of certain assumptions about the future, including economic forecasts, anticipated energy and commodity prices, cost estimates, construction schedules, power demand forecasts, potential regulatory environments, and the appropriate generation mix to meet demand;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Circumstances that cause TVA to change its determinations regarding the appropriate mix of generation assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inability to continue to operate certain assets, especially nuclear facilities, including due to the inability to obtain, or loss of, regulatory approval for the operation of assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Physical attacks, threats, or other interference causing damage to TVA's facilities or interfering with TVA's operations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Unforeseeable occurrences negatively impacting TVA assets or their supporting infrastructure;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Events at TVA facilities, which, among other things, could result in loss of life, damage to the environment, damage to or loss of the facility, or damage to the property of others;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Disruption of supplies of fuel, purchased power, or other critical items or services, which may result from, among other things, economic conditions, weather conditions, physical or cyber attacks, political developments, international trade restrictions or tariffs, legal actions, mine closures or reduced mine production, increases in fuel exports, environmental regulations affecting TVA's suppliers, transportation or delivery constraints, shortages of raw materials, supply chain difficulties, labor shortages, force majeure events, forced outages, intentional defaults, strikes, inflation, or similar events and which may, among other things, hinder TVA's ability to operate its assets, complete projects on time and on budget, and meet its contractual obligations to deliver power;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Global conflicts, terrorist activities, or military actions by the United States ("U.S.") government and its allies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Cyber attacks on TVA's assets or the assets of third parties upon which TVA relies, which may become more frequent and sophisticated due to advances in artificial intelligence ("AI");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The failure of TVA's information technology systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Lower future demand for electricity than TVA currently expects or is financially planning for, which would lead to unexpected revenue constraints that could negatively impact TVA's ability to meet financial obligations, including those associated with financing of projects to meet the anticipated demand;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Higher future demand for electricity than TVA can address through execution of its current asset strategy, which could require TVA to purchase additional generation or capacity at rates higher than TVA can produce electricity itself, take emergency measures to curtail load, raise rates, and/or waitlist prospective industrial or commercial customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failure to attract or retain an appropriately qualified workforce;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Changes in the membership of the TVA Board of Directors ("TVA Board") or TVA senior management, which may impact how TVA operates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inability to adapt to meet changing business conditions as a result of the recent loss of quorum of the TVA Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Weather conditions, including changing weather patterns, extreme weather conditions, and other events such as flooding, droughts, wildfires, heat waves, and snow or ice storms that may result from climate change, which may hamper TVA's ability to supply power, cause customers' demand for power to exceed TVA's then-present power supply, pose health, safety, or environmental risks, or otherwise negatively impact TVA's operations or financial condition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Events affecting the supply or quality of water from the Tennessee River system or Cumberland River system, or elsewhere, which could interfere with TVA's ability to generate power;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Ineffectiveness of TVA's financial control system to control issues and instances of fraud or to prevent or detect errors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inability to use regulatory accounting for certain costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inability of TVA to implement its business strategy successfully, including due to the increased use in the public of distributed energy resources or energy-efficiency programs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inability of TVA to achieve or maintain its cost reduction goals, including pursuant to its Enterprise Transformation Program ("ETP"), which may require TVA to increase rates and/or issue more debt than planned;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failure of TVA's organizational structure to adequately support TVA's anticipated business needs or enable it to meet the needs of its current or potential customers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Inability of TVA to adapt its business model to changes in the utility industry and customer preferences and to remain cost competitive;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reliability or creditworthiness of counterparties including but not limited to customers, suppliers, renewable resource providers, and financial institutions;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Costs or liabilities that are not anticipated in TVA's financial statements for third-party claims, natural resource damages, environmental cleanup activities, or fines or penalties associated with unexpected events such as failures of a facility or infrastructure;

**1. Summary of Significant Accounting Policies** 

*General*

The Tennessee Valley Authority ("TVA") prepares its consolidated interim financial statements in conformity with accounting principles generally accepted in the United States of America ("GAAP") for consolidated interim financial information. Accordingly, TVA's consolidated interim financial statements do not include all of the information and notes required by GAAP for annual financial statements. As such, they should be read in conjunction with the audited financial statements for the year ended September 30, 2024, and the notes thereto, which are contained in TVA's Annual Report on Form 10-K for the year ended September 30, 2024 (the "Annual Report"). In the opinion of management, all adjustments (consisting of items of a normal recurring nature) considered necessary for fair presentation are included on the consolidated interim financial statements.

*Fiscal Year*

TVA's fiscal year ends September 30. Years (2025, 2024, etc.) refer to TVA's fiscal years unless they are preceded by "CY," in which case the references are to calendar years.

*Basis of Presentation*

The accompanying consolidated interim financial statements, which have been prepared in accordance with GAAP, include the accounts of TVA and variable interest entities ("VIEs") of which TVA is the primary beneficiary. See Note 10 — *Variable Interest Entities*. Intercompany balances and transactions have been eliminated in consolidation.

*Use of Estimates*

The preparation of financial statements requires TVA to estimate the effects of various matters that are inherently uncertain as of the date of the consolidated financial statements. Although the consolidated financial statements are prepared in conformity with GAAP, TVA is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses, reported during the reporting period. Each of these estimates varies in regard to the level of judgment involved and its potential impact on TVA's financial results. Estimates are considered critical either when a different estimate could have reasonably been used, or where

------

**<u>[Ta](#i474611c3326c4e3381fecd9b884e27f6_10)[ble of Contents](#i474611c3326c4e3381fecd9b884e27f6_10)</u> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Draft 4.0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;07/24/2025 5:00 PM**

changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact TVA's financial condition, results of operations, or cash flows.

*Cash, Cash Equivalents, and Restricted Cash* 

Cash includes cash on hand, non-interest bearing cash, and deposit accounts. All highly liquid investments with original maturities of three months or less are considered cash equivalents. Cash and cash equivalents that are restricted, as to withdrawal or use under the terms of certain contractual agreements, are recorded in Other long-term assets on the Consolidated Balance Sheets. Restricted cash and cash equivalents include cash held in trusts that are currently restricted for TVA economic development loans and for certain TVA environmental programs in accordance with agreements related to compliance with certain environmental regulations.

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

---

|:---|:---|:---|
| **Cash, Cash Equivalents, and Restricted Cash**<br>(in millions) | **Cash, Cash Equivalents, and Restricted Cash**<br>(in millions) | **Cash, Cash Equivalents, and Restricted Cash**<br>(in millions) |
| | **At June 30, 2025** | **At September 30, 2024** |
| Cash and cash equivalents | $501 | $502 |
| Restricted cash and cash equivalents included in Other long-term assets | 21 | 21 |
| Total cash, cash equivalents, and restricted cash | $522 | $523 |

---

*Allowance for Uncollectible Accounts* 

TVA recognizes an allowance that reflects the current estimate for credit losses expected to be incurred over the life of the financial assets based on historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amounts. The appropriateness of the allowance is evaluated at the end of each reporting period.

To determine the allowance for trade receivables, TVA considers historical experience and other currently available information, including events such as customer bankruptcy and/or a customer failing to fulfill payment arrangements by the due date. TVA's corporate credit department also performs an assessment of the financial condition of customers and the credit quality of the receivables. In addition, TVA reviews other reasonable and supportable forecasts to determine if the allowance for uncollectible amounts should be further adjusted in accordance with the accounting guidance for Current Expected Credit Losses.

To determine the allowance for loans receivables, TVA aggregates loans into the appropriate pools based on the existence of similar risk characteristics such as collateral types and internal assessed credit risks. In situations where a loan exhibits unique risk characteristics and is no longer expected to experience similar risks to the rest of its pool, the loan will be evaluated separately. TVA derives an annual loss rate based on historical loss and then adjusts the rate to reflect TVA's consideration of available information on current conditions and reasonable and supportable future forecasts. This information may include economic and business conditions, default trends, and other internal and external factors. For periods beyond the reasonable and supportable forecast period, TVA uses the current calculated long-term average historical loss rate for the remaining life of the loan portfolio.

The allowance for uncollectible accounts was $10 million and less than $1 million at June 30, 2025, and September 30, 2024, respectively, for trade accounts receivable. At June 30, 2025, the allowance for uncollectible accounts included $8 million related to one local power company customer ("LPC"). Additionally, loans receivable of $114 million and $105 million at June 30, 2025, and September 30, 2024, respectively, are included in Accounts receivable, net and Other long-term assets, for the current and long-term portions, respectively. Loans receivables are reported net of allowances for uncollectible accounts of $2 million at both June 30, 2025, and September 30, 2024.

*Pre-Commercial Plant Operations*

As part of the process of completing the construction of a generating unit, the electricity produced is used to serve the demands of the electric system. TVA estimates revenues earned during pre-commercial operations at the fair value of the energy delivered based on TVA's hourly incremental dispatch cost. Pre-commercial plant operations began on Paradise combustion turbine ("CT") Units 5-7 in the first quarter of 2024, and the units became operational on December 29, 2023. Estimated revenue of $3 million related to this project was capitalized to offset project costs for the nine months ended June 30, 2024, all of which was recognized in the three months ended December 31, 2023. TVA also capitalized related fuel costs for this project of $3 million for the nine months ended June 30, 2024, all of which was recognized in the three months ended December

31, 2023. Pre-commercial plant operations began on Johnsonville Aeroderivative CT Units 21-30 during the nine months ended June 30, 2025, and Units 21-25 and 27-30 became operational on May 6, 2025. Estimated revenue of $1 million and $3 million related to this project was capitalized to offset project costs for the three and nine months ended June 30, 2025, respectively.

TVA also capitalized related fuel costs for this project of $2 million and $6 million for the three and nine months ended June 30, 2025, respectively.

*Depreciation*&nbsp;&nbsp;&nbsp;&nbsp;

TVA accounts for depreciation of its properties using the composite depreciation convention of accounting. Under the composite method, assets with similar economic characteristics are grouped and depreciated as one asset. Depreciation is generally computed on a straight-line basis over the estimated service lives of the various classes of assets. The estimation of asset useful lives requires management judgment, supported by external depreciation studies of historical asset retirement experience. Depreciation rates are determined based on external depreciation studies that are updated approximately every five years, with the latest study implemented during the first quarter of 2022. Depreciation expense was $484 million and $463 million for the three months ended June 30, 2025 and 2024, respectively. Depreciation expense was $1.4 billion for both the nine months ended June 30, 2025 and 2024. See Note 7 — *Plant Closures* for a discussion of the impact of plant closures.

 **2. Impact of New Accounting Standards and Interpretations** &nbsp;&nbsp;&nbsp;&nbsp;

The following accounting standards or rules have been issued but as of June 30, 2025, were not effective and have not been adopted by TVA:

---

| | |
|:---|:---|
| **Improvements to Reportable Segment Disclosures** | **Improvements to Reportable Segment Disclosures** |
| **Description** | This guidance improves reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. The amendments require a public entity to disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit and loss. It also requires a public entity that has a single reportable segment to provide all of the disclosures required by the amendments and all existing segment disclosures. The amendments are effective for public entities for fiscal years beginning after December 15, 2023, and interim periods in fiscal years beginning after December 15, 2024. Upon adoption, a public entity should apply the amendments retrospectively to all prior periods presented in the financial statements. |
| **Effective Date for TVA** | Annual disclosures to be adopted for the fiscal year ending September 30, 2025 and interim period disclosures to be adopted beginning October 1, 2025. |
| **Effect on the Financial Statements or Other Significant Matters** | The adoption of this standard will result in TVA including the additional required disclosures, and TVA does not expect an impact on its financial condition, results of operations, or cash flows. |

---

| | |
|:---|:---|
| **Enhancement and Standardization of Climate-Related Disclosures for Investors** | **Enhancement and Standardization of Climate-Related Disclosures for Investors** |
| **Description** | In March 2024, the Securities and Exchange Commission ("SEC") adopted its climate-related final rule (SEC Release No. 34-99678, The Enhancement and Standardization of Climate-Related Disclosures for Investors). In April 2024, the SEC voluntarily stayed the new rule as a result of pending legal challenges, in March 2025, the SEC withdrew its legal defense of the rule, and in April 2025, the United States Court of Appeals for the Eighth Circuit suspended the litigation over the validity of the rule. The new rule, if implemented as adopted, will require registrants to provide certain climate-related information in their annual reports and registration statements and will also require the dollar impact of severe weather events and other natural conditions, as well as amounts related to carbon offsets and renewable energy credits or certificates, to be disclosed in the audited financial statements in certain circumstances. If the new rule is implemented as adopted, the disclosure requirements will begin phasing in for fiscal years beginning on or after January 1, 2027 for non-accelerated filers. |
| **Effective Date for TVA** | Fiscal year beginning October 1, 2027. |
| **Effect on the Financial Statements or Other Significant Matters** | TVA is currently evaluating the impact of the rule on its disclosures. |
| **Disaggregation of Income Statement Expenses** | **Disaggregation of Income Statement Expenses** |
| **Description** | This guidance improves the disclosures about a public entity's expenses in the notes to the financial statements and requires disclosure of specified information about certain costs and expenses. The amendments require a public entity to disclose, on an annual and interim basis, purchases of inventory, employee compensation, depreciation, intangible asset amortization, and depletion for each income statement line item that contains those expenses. Specified expenses, gains, or losses that are already disclosed under existing US GAAP are required to be included in the disaggregated income statement expense line item disclosures, and any relevant remaining amounts need to be described qualitatively. Separate disclosures of total selling expenses and an entity's definition of those expenses are also required. The amendments are effective for public entities for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027. Upon adoption, a public entity can apply the amendments prospectively or apply them retrospectively to all prior periods presented in the financial statements. |
| **Effective Date for TVA** | Fiscal year beginning October 1, 2027, and interim periods beginning October 1, 2028. |
| **Effect on the Financial Statements or Other Significant Matters** | The adoption of this standard will result in TVA including the additional required disclosures, and TVA does not expect an impact on its financial condition, results of operations, or cash flows. |

**3. Restructuring**

TVA's demand continues to grow, driving the need for significant future capital investment. TVA must continue to drive efficiencies and cost savings across the enterprise to provide affordable, reliable electricity, while funding the capital investment needed to meet growing demand. This effort has evolved into an Enterprise Transformation Program ("ETP") focused on improving financial health, enhancing asset performance, automating processes, optimizing third-party spend through supply chain, and making the workforce more efficient. As part of these efforts, certain employees are eligible for severance payments. These amounts are recognized in Operating and maintenance expense on TVA's Consolidated Statement of Operations in the period incurred. Severance costs that have been incurred but not paid are included in Accounts payable and accrued liabilities on TVA's Consolidated Balance Sheets. The table below summarizes the activity related to severance costs:

---

| | |
|:---|:---|
| **Severance Cost Liability Activity**<br>(in millions) | **Severance Cost Liability Activity**<br>(in millions) |

<u>Note</u>

(1) To determine the allowance for trade receivables, TVA considers historical experience and other currently available information, including events such as customer bankruptcy and/or a customer failing to fulfill payment arrangements by the due date, among other considerations. See Note 1 — *Summary of Significant Accounting Policies — Allowance for Uncollectible Accounts*. At June 30, 2025, the allowance for uncollectible accounts included $8 million related to one LPC customer.

*Commodity Contract Derivative Assets.* See Note 14 *— Risk Management Activities and Derivative Transactions — Derivatives Not Receiving Hedge Accounting Treatment — Commodity Derivatives* and *— Commodity Derivatives under the FHP* for a discussion of TVA's commodity contract derivatives.

**7. Plant Closures** 

*Background*

TVA must continuously evaluate all generating assets to ensure an optimal energy portfolio that provides safe, clean, and reliable power while maintaining flexibility and fiscal responsibility to the people of the Tennessee Valley. In January 2023, TVA issued its Record of Decision to retire the two coal-fired units at Cumberland Fossil Plant ("Cumberland") by the end of CY 2026 and CY 2028. In April 2024, TVA issued its Record of Decision to retire the nine coal-fired units at Kingston Fossil Plant ("Kingston") by CY 2027. TVA is evaluating the impact of retiring the balance of the coal-fired fleet by 2035, and that evaluation includes environmental reviews, public input, and TVA Board of Directors ("TVA Board") approval. TVA is also reviewing how recent executive orders impact supply and planning needs related to its coal-fired fleet.

*Financial Impact*

TVA's policy is to adjust depreciation rates to reflect the most current assumptions, ensuring units will be fully depreciated by the applicable retirement dates. TVA's decision to retire the two units at Cumberland is estimated to result in approximately $16 million of additional depreciation quarterly, which does not include any potential impact from additions or retirements to net completed plant. The cumulative impact approximates $160 million of additional depreciation since January 2023, related to this decision. In addition, TVA's decision to retire the nine units at Kingston is estimated to result in approximately $9 million of additional depreciation quarterly, which does not include any potential impact from additions or retirements to net completed plant. The cumulative impact approximates $45 million of additional depreciation since April 2024, related to this decision.

TVA also recognized $12 million and $11 million in operating and maintenance expense during the nine months ended June 30, 2025 and 2024, respectively, related to additional inventory reserves and write-offs related to TVA's coal-fired fleet, including Kingston and Cumberland. Of these amounts, $4 million was recognized during both the three months ended June 30, 2025 and 2024.

| EnergyRight<sup>®</sup> receivables, net | 44 | 44 |
| Commodity contract derivative assets | 17 | 2 |
| Other | 85 | 88 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total other long-term assets | $490 | $344 |

---

*Loans and Other Long-Term Receivables*. At June 30, 2025, and September 30, 2024, the carrying amount of the loans receivable, net of discount, reported in Accounts receivable, net was $3 million and $21 million, respectively. Loans receivables are reported net of allowances for uncollectible accounts. See Note 1 — *Summary of Significant Accounting Policies* — *Allowance for Uncollectible Accounts*.

The allowance components, which consist of a collective allowance and specific loans allowance, are based on the risk characteristics of TVA's loans. Loans that share similar risk characteristics are evaluated on a collective basis in measuring credit losses, while loans that do not share similar risk characteristics with other loans are evaluated on an individual basis.

*Cloud Assets.* At June 30, 2025, and September 30, 2024, the carrying amount of the cloud assets reported in Other current assets was $3 million and $13 million, respectively.

*Prepaid Long-Term Service Agreements*. At June 30, 2025, and September 30, 2024, prepayments of $16 million and $7 million, respectively, were recorded in Other current assets.

*EnergyRight*<sup>®</sup> *Receivables*. In association with the EnergyRight<sup>®</sup> program, TVA's LPCs offer financing to end-use customers for the purchase of energy-efficient equipment. Depending on the nature of the energy-efficiency project, loans may have a maximum term of five years or 10 years. TVA purchases the resulting loans receivable from its LPCs. The loans receivable are then transferred to a third-party bank with which TVA has agreed to repay in full any loans receivable that have been in default for 180 days or more or that TVA has determined are uncollectible. Given this continuing involvement, TVA accounts for the transfer of the loans receivable as secured borrowings. The current and long-term portions of the loans receivable are reported in Accounts receivable, net and Other long-term assets, respectively, on TVA's Consolidated Balance Sheets. At both June 30, 2025, and September 30, 2024, the carrying amount of the loans receivable, net of discount, reported in Accounts receivable, net was $12 million. See Note 11 — *Other Long-Term Liabilities* for information regarding the associated financing obligation.

*Commodity Contract Derivative Assets.* See Note 14 *— Risk Management Activities and Derivative Transactions — Derivatives Not Receiving Hedge Accounting Treatment — Commodity Derivatives* and *— Commodity Derivatives under the FHP* for a discussion of TVA's commodity contract derivatives.

 **9. Regulatory Assets and Liabilities** 

TVA records certain assets and liabilities that result from the regulated ratemaking process that would not be recorded under GAAP for non-regulated entities. As such, certain items that would generally be reported in earnings or that would impact the Consolidated Statements of Operations are recorded as regulatory assets or regulatory liabilities. Regulatory assets generally represent incurred costs that have been deferred because such costs are probable of future recovery in customer rates. Regulatory liabilities generally represent obligations to make refunds to customers for previous collections for costs that are not likely to be incurred or deferral of gains that will be credited to customers in future periods. Components of regulatory assets and regulatory liabilities are summarized in the table below.

**10. Variable Interest Entities** 

A variable interest entity ("VIE") is an entity that either (i) has insufficient equity to permit the entity to finance its activities without additional subordinated financial support or (ii) has equity investors who lack the characteristics of owning a controlling financial interest. When TVA determines that it has a variable interest in a VIE, a qualitative evaluation is performed to assess which interest holders have the power to direct the activities that most significantly impact the economic performance of the entity and have the obligation to absorb losses or receive benefits that could be significant to the entity. The evaluation considers the purpose and design of the business, the risks that the business was designed to create and pass along to other entities, the activities of the business that can be directed and which party can direct them, and the expected relative impact of those activities on the economic performance of the business through its life. TVA has the power to direct the activities of an entity when it has the ability to make key operating and financing decisions, including, but not limited to, capital investment and the issuance of debt. Based on the evaluation of these criteria, TVA has determined it is the primary beneficiary of certain entities and as such is required to account for the VIEs on a consolidated basis.

*John Sevier VIEs*

In 2012, TVA entered into a $1.0 billion construction management agreement and lease financing arrangement with John Sevier Combined Cycle Generation LLC ("JSCCG") for the completion and lease by TVA of the John Sevier Combined Cycle Facility ("John Sevier CCF"). JSCCG is a special single-purpose limited liability company formed in January 2012 to finance the John Sevier CCF through a $900 million secured note issuance (the "JSCCG notes") and the issuance of $100 million of membership interests subject to mandatory redemption. The membership interests were purchased by John Sevier Holdco LLC ("Holdco"). Holdco is a special single-purpose entity, also formed in January 2012, established to acquire and hold the membership interests in JSCCG. A non-controlling interest in Holdco is held by a third party through nominal membership interests, to which none of the income, expenses, and cash flows are allocated.

The membership interests held by Holdco in JSCCG were purchased with proceeds from the issuance of $100 million of secured notes (the "Holdco notes") and are subject to mandatory redemption pursuant to a schedule of amortizing, semi-annual payments due each January 15 and July 15, with a final payment due in January 2042. The payment dates for the mandatorily redeemable membership interests are the same as those of the Holdco notes. The sale of the JSCCG notes, the membership interests in JSCCG, and the Holdco notes closed in January 2012. The JSCCG notes are secured by TVA's lease payments, and the Holdco notes are secured by Holdco's investment in, and amounts receivable from, JSCCG. TVA's lease payments to JSCCG are equal to and payable on the same dates as JSCCG's and Holdco's semi-annual debt service payments. In addition to the lease payments, TVA pays administrative and miscellaneous expenses incurred by JSCCG and Holdco. Certain agreements related to this transaction contain default and acceleration provisions.

Due to its participation in the design, business activity, and credit and financial support of JSCCG and Holdco, TVA has determined that it has a variable interest in both of these entities. Based on its analysis, TVA has concluded that it is the primary beneficiary of JSCCG and Holdco and, as such, is required to account for the VIEs on a consolidated basis. Holdco's membership interests in JSCCG are eliminated in consolidation.

*Southaven VIE*

In 2013, TVA entered into a $400 million lease financing arrangement with Southaven Combined Cycle Generation LLC ("SCCG") for the lease by TVA of the Southaven Combined Cycle Facility ("Southaven CCF"). SCCG is a special single-purpose limited liability company formed in June 2013 to finance the Southaven CCF through a $360 million secured notes issuance (the "SCCG notes") and the issuance of $40 million of membership interests subject to mandatory redemption. The membership interests were purchased by Southaven Holdco LLC ("SHLLC"). SHLLC is a special single-purpose entity, also formed in June 2013, established to acquire and hold the membership interests in SCCG. A non-controlling interest in SHLLC is held by a third party through nominal membership interests, to which none of the income, expenses, and cash flows of SHLLC are allocated.

The membership interests held by SHLLC were purchased with proceeds from the issuance of $40 million of secured notes (the "SHLLC notes") and are subject to mandatory redemption pursuant to a schedule of amortizing, semi-annual payments due each February 15 and August 15, with a final payment due on August 15, 2033. The payment dates for the mandatorily redeemable membership interests are the same as those of the SHLLC notes, and the payment amounts are sufficient to provide returns on, as well as returns of, capital until the investment has been repaid to SHLLC in full. The rate of return on investment to SHLLC is seven percent, which is reflected as interest expense in the Consolidated Statements of Operations. SHLLC is required to pay a pre-determined portion of the return on investment to Seven States Southaven, LLC on each lease payment date as agreed in SHLLC's formation documents (the "Seven States Return"). The current and long-term portions of the Membership interests of VIE subject to mandatory redemption are included in Accounts payable and accrued liabilities and Other long-term liabilities, respectively.

The payment dates for the mandatorily redeemable membership interests are the same as those of the SHLLC notes. The SCCG notes are secured by TVA's lease payments, and the SHLLC notes are secured by SHLLC's investment in, and amounts receivable from, SCCG. TVA's lease payments to SCCG are payable on the same dates as SCCG's and SHLLC's semi-annual debt service payments and are equal to the sum of (i) the amount of SCCG's semi-annual debt service payments, (ii) the amount of SHLLC's semi-annual debt service payments, and (iii) the amount of the Seven States Return. In addition to the lease payments, TVA pays administrative and miscellaneous expenses incurred by SCCG and SHLLC. Certain agreements related to this transaction contain default and acceleration provisions.

In the event that TVA were to choose to exercise an early buy out feature of the Southaven facility lease, in part or in whole, TVA must pay to SCCG amounts sufficient for SCCG to repay or partially repay on a pro rata basis the membership interests held by SHLLC, including any outstanding investment amount plus accrued but unpaid return. TVA also has the right, at any time and without any early redemption of the other portions of the Southaven facility lease payments due to SCCG, to fully repay SHLLC's investment, upon which repayment SHLLC will transfer the membership interests to a designee of TVA.

TVA participated in the design, business activity, and financial support of SCCG and has determined that it has a direct variable interest in SCCG resulting from risk associated with the value of the Southaven CCF at the end of the lease term. Based on its analysis, TVA has determined that it is the primary beneficiary of SCCG and, as such, is required to account for the VIE on a consolidated basis.

*Johnsonville VIE*

In October 2024, TVA entered into an $800 million construction management agreement and lease financing arrangement with Johnsonville Aeroderivative Combustion Turbine Generation LLC ("JACTG") for the completion and lease by TVA of the Johnsonville Aeroderivative Combustion Turbine Facility ("Johnsonville Facility"). JACTG is a special single-purpose limited liability company formed in September 2024 to finance the Johnsonville Facility through a $720 million secured note issuance (the "JACTG notes") and the issuance of $80 million of membership interests subject to mandatory redemption. The membership interests were purchased by Johnsonville Holdco LLC ("JHLLC"). JHLLC is a special single-purpose entity, also formed in September 2024, established to acquire and hold the membership interests in JACTG. A non-controlling interest in JHLLC is held by a third-party through nominal membership interests, to which none of the income, expenses, and cash flows are allocated.

The membership interests held by JHLLC in JACTG were purchased with proceeds from the issuance of $80 million of secured notes (the "JHLLC notes") and are subject to mandatory redemption pursuant to a schedule of amortizing, semi-annual payments due each April 1 and October 1, with a final payment due in October 2054. The payment dates for the mandatorily redeemable membership interests are the same as those of the JHLLC notes. The sale of the JACTG notes, the membership interests in JACTG, and the JHLLC notes closed in October 2024. The JACTG notes are secured by TVA's lease payments, and the JHLLC notes are secured by JHLLC's investment in, and amounts receivable from, JACTG. TVA's lease payments to JACTG are equal to and payable on the same dates as JACTG's and JHLLC's semi-annual debt service payments. In addition to the lease payments, TVA pays administrative and miscellaneous expenses incurred by JACTG and JHLLC. Certain agreements related to this transaction contain default and acceleration provisions.

&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;Due to its participation in the design, business activity, and credit and financial support of JACTG and JHLLC, TVA has determined that it has a variable interest in both of these entities. Based on its analysis, TVA has concluded that it is the primary beneficiary of JACTG and JHLLC and, as such, is required to account for the VIEs on a consolidated basis. JHLLC's membership interests in JACTG are eliminated in consolidation.

<u>Note</u>

(1) Includes $316 million and $283 million at June 30, 2025, and September 30, 2024, respectively, in Current liabilities.

Revisions in non-nuclear estimates decreased the liability balance by $24 million for the nine months ended June 30, 2025. The decrease was primarily attributable to a change in closure liabilities of $34 million at Paradise Fossil Plant based on scope changes, new vendor bids, and updated cost estimates for activities associated with final closure. The decrease was partially offset by increased revisions in estimates of $16 million related to the final legacy coal combustion residual rule ("Legacy CCR Rule").

The interest rate on any borrowing under these facilities varies based on market factors and the rating of TVA's senior unsecured, long-term, non-credit-enhanced debt. TVA is required to pay an unused facility fee on the portion of the total $2.7 billion that TVA has not borrowed or committed under letters of credit. This fee, along with letter of credit fees, may fluctuate depending on the rating of TVA's senior unsecured, long-term, non-credit-enhanced debt. At June 30, 2025, and September 30, 2024, there were $517 million and $566 million, respectively, of letters of credit outstanding under these facilities, and there were no borrowings outstanding. TVA's letters of credit are primarily posted as collateral under TVA's interest rate swaps. See Note 14 — *Risk Management Activities and Derivative Transactions* — *Other Derivative Instruments* — *Collateral.* TVA may also post collateral for TVA's currency swaps, for commodity derivatives under the Financial Hedging Program ("FHP"), or for certain transactions with third parties that require TVA to post letters of credit.

The following table provides additional information regarding TVA's funding available under the four revolving credit facilities:

TVA and the United States ("U.S.") Department of the Treasury ("U.S. Treasury"), pursuant to the Tennessee Valley Authority Act of 1933, as amended ("TVA Act"), have entered into a memorandum of understanding under which the U.S. Treasury provides TVA with a $150 million credit facility. This credit facility was renewed for 2025 with a maturity date of September 30, 2025. Access to this credit facility or other similar financing arrangements with the U.S. Treasury has been

available to TVA since the 1960s. TVA can borrow under the U.S. Treasury credit facility only if it cannot issue bonds, notes, or other evidences of indebtedness (collectively, "Bonds") in the market on reasonable terms, and TVA considers the U.S. Treasury credit facility a secondary source of liquidity. The interest rate on any borrowing under this facility is based on the average rate on outstanding marketable obligations of the U.S. with maturities from date of issue of 12 months or less. There were no outstanding borrowings under the facility at June 30, 2025. The availability of this credit facility may be impacted by how the U.S. government addresses the possibility of approaching its debt limit.

**14. Risk Management Activities and Derivative Transactions** 

TVA is exposed to various risks related to commodity prices, investment prices, interest rates, currency exchange rates, and inflation as well as counterparty credit and performance risks. To help manage certain of these risks, TVA has historically entered into various derivative transactions, principally commodity option contracts, forward contracts, swaps, swaptions, futures, and options on futures.

*Overview of Accounting Treatment*

TVA recognizes certain of its derivative instruments as either assets or liabilities on its Consolidated Balance Sheets at fair value. The accounting for changes in the fair value of these instruments depends on (1) whether TVA uses regulatory accounting to defer the derivative gains and losses, (2) whether the derivative instrument has been designated and qualifies for hedge accounting treatment, and (3) if so, the type of hedge relationship (for example, cash flow hedge).

The following tables summarize the accounting treatment that certain of TVA's financial derivative transactions receive:

<u>Note</u>

(1) There were no amounts excluded from effectiveness testing for any of the periods presented. Based on forecasted foreign currency exchange rates, TVA expects to reclassify approximately $1 million of loss from AOCI to Interest expense within the next 12 months to offset amounts anticipated to be recorded in Interest expense related to the forecasted exchange gains on the debt.

<u>Notes</u>

(1) All of TVA's derivative instruments that do not receive hedge accounting treatment have unrealized gains (losses) that would otherwise be recognized in income but instead are deferred as regulatory assets and liabilities. As such, there were no related gains (losses) recognized in income for these unrealized gains (losses) for the three and nine months ended June 30, 2025 and for the three and nine months ended June 30, 2024.

*Cash Flow Hedging Strategy for Currency Swaps*

To protect against exchange rate risk related to British pound sterling denominated Bond transactions, TVA entered into foreign currency hedges at the time the Bond transactions occurred. TVA had two currency swaps outstanding at June 30, 2025, with total currency exposure of £400 million and expiration dates in 2032 and 2043.

When the dollar strengthens against the British pound sterling, the exchange gain on the Bond liability and related accrued interest is offset by an equal amount of loss on the swap contract that is reclassified out of AOCI. Conversely, the exchange loss on the Bond liability and related accrued interest is offset by an equal amount of gain on the swap contract that is reclassified out of AOCI. All such exchange gains or losses on the Bond liability and related accrued interest are included in Long-term debt, net and Accrued interest, respectively. The offsetting exchange losses or gains on the swap contracts are recognized in AOCI. If any gain (loss) were to be incurred as a result of the early termination of the foreign currency swap contract, the resulting income (expense) would be amortized over the remaining life of the associated Bond as a component of Interest expense. The values of the currency swap liabilities are included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets.

*Derivatives Not Receiving Hedge Accounting Treatment* 

*Interest Rate Derivatives*. Generally TVA uses interest rate swaps to fix variable short-term debt to a fixed rate, and TVA uses regulatory accounting treatment to defer the mark-to-market ("MtM") gains and losses on its interest rate swaps. The net deferred unrealized gains and losses are classified as regulatory liabilities or assets on TVA's Consolidated Balance Sheets and are included in the ratemaking formula when gains or losses are realized. The values of these derivatives are included in Accounts payable and accrued liabilities, Accrued interest, and Other long-term liabilities on the Consolidated Balance Sheets, and realized gains and losses, if any, are included on TVA's Consolidated Statements of Operations. For the three months ended June 30, 2025 and 2024, the changes in fair market value of the interest rate swaps resulted in the reduction in unrealized losses of $6 million and $32 million, respectively. For the nine months ended June 30, 2025 and 2024, the changes in fair market value of the interest rate swaps resulted in the reduction in unrealized losses of $141 million and the increase in unrealized losses of $63 million, respectively. TVA may hold short-term debt balances lower than the notional amount of the interest rate swaps from time to time due to changes in business conditions and other factors. While actual balances vary, TVA generally plans to maintain average balances of short-term debt equal to or in excess of the combined notional amount of the interest rate swaps.

*&nbsp;&nbsp;&nbsp;&nbsp;*

*Commodity Derivatives*. TVA enters into certain derivative contracts for natural gas that require physical delivery of the contracted quantity of the commodity. TVA may also enter into power purchase agreements ("PPAs") that provide an option to financially settle contracted power deliveries. This option creates an embedded derivative in the hosting PPA. TVA marks to market these contracts and defers the unrealized gains (losses) as regulatory liabilities (assets). At June 30, 2025, TVA's natural gas contract derivatives had terms of up to 10 years.

*Commodity Derivatives under the FHP.* Currently, TVA is hedging exposure to the price of natural gas under the FHP. There is no Value at Risk aggregate transaction limit under the current FHP structure, but the TVA Board reviews and authorizes the use of tolerances and measures annually. TVA's FHP policy prohibits trading financial instruments under the FHP for speculative purposes. At June 30, 2025, TVA's natural gas swap contracts under the FHP had remaining terms of up to five years.

| Total derivatives subject to master netting or similar arrangement | $794 | $1122 |

---

<u>Notes</u>

(1) Offsetting amounts include counterparty netting of derivative contracts. Except as discussed below, there were no other material offsetting amounts on TVA's Consolidated Balance Sheets at either June 30, 2025, or September 30, 2024.

(2) At June 30, 2025, the gross derivative asset and gross derivative liability were $54 million and $55 million, respectively, with offsetting amounts for each totaling $30 million. At September 30, 2024, the gross derivative asset and gross derivative liability were $4 million and $165 million, respectively, with offsetting amounts for each totaling $4 million.

(3) Letters of credit of $411 million and $535 million were posted as collateral at June 30, 2025, and September 30, 2024, respectively, to partially secure the liability positions of one of the interest rate swaps in accordance with the collateral requirements for this derivative.

*Other Derivative Instruments* 

*Investment Fund Derivatives*. Investment funds consist primarily of funds held in the Nuclear Decommissioning Trust ("NDT"), the Asset Retirement Trust ("ART"), the Supplemental Executive Retirement Plan ("SERP"), the Deferred Compensation Plan ("DCP"), and the Restoration Plan ("RP"). See Note 15 — *Fair Value Measurements* — *Investment Funds* for a discussion of the trusts, plans, and types of investments. The NDT and ART may invest in derivative instruments which may include swaps, futures, options, forwards, and other instruments. At June 30, 2025, and September 30, 2024, the NDT held investments in forward contracts to purchase debt securities. The fair values of these derivatives were in net asset positions totaling $18 million and $11 million at June 30, 2025, and September 30, 2024, respectively.

*Collateral*. TVA's interest rate swaps, currency swaps, and commodity derivatives under the FHP contain contract provisions that require a party to post collateral (in a form such as cash or a letter of credit) when the party's liability balance under the agreement exceeds a certain threshold. At June 30, 2025, the aggregate fair value of all derivative instruments with credit-risk related contingent features that were in a liability position was $794 million. TVA's collateral obligations at June 30, 2025, under these arrangements were $439 million, for which TVA had posted $411 million in letters of credit. These letters of credit reduce the available balance under the related credit facilities. TVA's assessment of the risk of its nonperformance includes a reduction in its exposure under the interest rate swap contracts as a result of this posted collateral.

For all of its derivative instruments with credit-risk related contingent features:

&nbsp;&nbsp;&nbsp;&nbsp;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If TVA remains a majority-owned U.S. government entity but S&P Global Ratings ("S&P") or Moody's Investors Service, Inc. ("Moody's") downgrades TVA's credit rating to AA or Aa2, respectively, TVA's collateral obligations would likely increase by $22 million, and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If TVA ceases to be majority-owned by the U.S. government, TVA's credit rating would likely be downgraded and TVA would be required to post additional collateral.

*Counterparty Risk* 

TVA may be exposed to certain risks when a counterparty has the potential to fail to meet its obligations in accordance with agreed terms. These risks may be related to credit, operational, or nonperformance matters. To mitigate certain counterparty risk, TVA analyzes the counterparty's financial condition prior to entering into an agreement, establishes credit limits, monitors the appropriateness of those limits, as well as any changes in the creditworthiness of the counterparty, on an ongoing basis, and when required, employs credit mitigation measures, such as collateral or prepayment arrangements and

master purchase and sale agreements.

*Customers*. TVA is exposed to counterparty credit risk associated with trade accounts receivable from delivered power sales to LPCs, and from industries and federal agencies directly served, all located in the Tennessee Valley region. Of the $1.8 billion and $1.7 billion of receivables from power sales outstanding at June 30, 2025, and September 30, 2024, respectively, nearly all of the counterparties were rated investment grade. The majority of the obligations of these customers that are not investment grade are secured by collateral. TVA is also exposed to risk from exchange power arrangements with a small number of investor-owned regional utilities related to either delivered power or the replacement of open positions of longer-term purchased power or fuel agreements. TVA believes its policies and procedures for counterparty performance risk reviews have generally protected TVA against significant exposure related to market and economic conditions. See Note 1 — *Summary of Significant Accounting Policies* — *Allowance for Uncollectible Accounts,* Note 4 — *Accounts Receivable, Net,* and Note 8 — *Other Long-Term Assets*.

TVA had revenue from two LPCs that collectively accounted for 16 percent of total operating revenues for both the nine months ended June 30, 2025 and 2024.

*Suppliers*. TVA assesses potential supplier performance risks, including procurement of fuel, purchased power, parts, and services. If suppliers are unable or unwilling to perform under TVA's existing contracts, if TVA is unable to obtain similar services or supplies from other vendors, or if there are significant changes to tariffs impacting suppliers, TVA could experience delays, disruptions, additional costs, or other operational outcomes that may impact generation, maintenance, and capital programs. If certain fuel or purchased power suppliers fail to perform under the terms of their contract with TVA, TVA might lose the money that it paid to the supplier under the contract and have to purchase replacement fuel or power on the spot market, perhaps at a significantly higher price than TVA was entitled to pay under the contract. In addition, TVA might not be able to acquire replacement fuel or power in a timely manner and thus might be unable to satisfy its own obligations to deliver power. TVA continues evaluating potential supplier performance risks and supplier impact but cannot determine or predict the duration of such risks/impacts or the extent to which such risks/impacts could affect TVA's business, operations, and financial results or cause potential business disruptions.

TVA continues to experience impacts due to inflation, supply chain material challenges, and labor availability. This has led to project delays, limited availability, and/or price increases for supplies and labor. TVA has been able to manage these challenges with limited business disruptions at this time; however, should pressures continue long term, TVA could experience more significant disruptions and pressure to further increase power rates.

<u>Natural Gas and Fuel Oil</u>. TVA purchases a significant amount of its natural gas requirements through contracts with a variety of suppliers and purchases substantially all of its fuel oil requirements on the spot market. TVA delivers to its gas fleet under firm and non-firm transportation contracts on multiple interstate natural gas pipelines. TVA contracts for storage capacity that allows for operational flexibility and increased supply during peak gas demand scenarios or supply disruptions. TVA uses contracts of various lengths and terms to meet the projected natural gas needs of its natural gas fleet. TVA also maintains on-site, fuel oil backup to operate at the majority of the CT sites in the event of major supply disruptions. In the event a supplier experiences an incident that limits its ability to fulfill its firm contractual obligations to supply TVA with natural gas, TVA intends to leverage its storage and balancing services and/or replace the volume with a third party to ensure reliability of generation.

<u>Coal</u>. To help ensure a reliable supply of coal, TVA had coal contracts with multiple suppliers as of June 30, 2025. The contracted supply of coal is sourced from several geographic regions of the U.S. and is delivered via barge and rail. As a result of emerging technologies, environmental regulations, industry trends, and natural gas market volatility over the past few years, coal suppliers are facing increased financial pressure, which has led to relatively poor credit ratings and bankruptcies, restructuring, mine closures, or other scenarios. A long-term continued decline in demand for coal could result in more consolidations, additional bankruptcies, restructuring, mine closures, or other scenarios.

<u>Nuclear Fuel</u>. Nuclear fuel is obtained predominantly through long-term uranium concentrate supply contracts, contracted conversion services, contracted enrichment services, or a combination thereof, and contracted fuel fabrication services. The supply markets for uranium concentrates and certain nuclear fuel services are subject to price fluctuations and availability restrictions. Supply market conditions may make procurement contracts subject to credit risk related to the potential nonperformance of counterparties. In the event of nonperformance by these or other suppliers, TVA believes that replacement uranium concentrate and nuclear fuel services can be obtained, although at prices that may be unfavorable when compared to the prices under the current supply agreements.

<u>Purchased Power</u>. TVA acquires power from a variety of power producers through long-term and short-term PPAs as well as through spot market purchases. Because of the reliability risk of purchased power, TVA requires that the PPAs contain certain counterparty performance assurance requirements to help insure counterparty performance during the term of the agreements.

<u>Other Suppliers</u>. Solar supply chain constraints, commodity price increases, legislative changes, trade policy issues, and investigations into and affecting solar panel imports have created challenges for the U.S. solar industry. TVA's existing solar PPA portfolio is not immune from these challenges. Similar to the experience of the rest of the industry, the majority of TVA's

contracted PPAs from previous requests for proposals that are not yet online have been impacted by project delays and price increases.

*Derivative Counterparties*. TVA has entered into physical and financial contracts that are classified as derivatives for hedging purposes, and TVA's NDT, ART, and qualified defined benefit plan ("pension plan") have entered into derivative contracts for investment purposes. If a counterparty to one of the physical or financial derivative transactions defaults, TVA might incur costs in connection with entering into a replacement transaction. If a counterparty to the derivative contracts into which the NDT, the ART, or the pension plan have entered for investment purposes defaults, the value of the investment could decline significantly or perhaps become worthless. TVA has concentrations of credit risk from the banking, coal, and gas industries because multiple companies in these industries serve as counterparties to TVA in various derivative transactions. At June 30, 2025, all of TVA's commodity derivatives under the FHP, currency swaps, and interest rate swaps were with counterparties whose Moody's credit ratings were A2 or higher. TVA classifies forward natural gas contracts as derivatives. At June 30, 2025, the forward natural gas contracts were with counterparties whose ratings ranged from B1 to A1.

**15. Fair Value Measurements** 

Fair value is determined based on the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the asset or liability's principal market, or in the absence of a principal market, the most advantageous market for the asset or liability in an orderly transaction between market participants. TVA uses market or observable inputs as the preferred source of values, followed by assumptions based on hypothetical transactions in the absence of market inputs.

*Valuation Techniques*

The measurement of fair value results in classification into a hierarchy by the inputs used to determine the fair value as follows:

---

| | |
|:---|:---|
| Level 1 | Unadjusted quoted prices in active markets accessible by the reporting entity for identical assets or liabilities. Active markets are those in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing. |
| Level 2 | Pricing inputs other than quoted market prices included in Level 1 that are based on observable market data and that are directly or indirectly observable for substantially the full term of the asset or liability. These include quoted market prices for similar assets or liabilities, quoted market prices for identical or similar assets in markets that are not active, adjusted quoted market prices, inputs from observable data such as interest rate and yield curves, volatilities and default rates observable at commonly quoted intervals, and inputs derived from observable market data by correlation or other means. |
| Level 3 | Pricing inputs that are unobservable, or less observable, from objective sources. Unobservable inputs are only to be used to the extent observable inputs are not available. These inputs maintain the concept of an exit price from the perspective of a market participant and should reflect assumptions of other market participants. An entity should consider all market participant assumptions that are available without unreasonable cost and effort. These are given the lowest priority and are generally used in internally developed methodologies to generate management's best estimate of the fair value when no observable market data is available. |

---

A financial instrument's level within the fair value hierarchy (where Level 1 is the highest and Level 3 is the lowest) is based on the lowest level of input significant to the fair value measurement.

The following sections describe the valuation methodologies TVA uses to measure different financial instruments at fair value. Except for gains and losses on SERP, DCP, and RP assets, all changes in fair value of these assets and liabilities have been recorded as changes in regulatory assets, regulatory liabilities, or AOCI on TVA's Consolidated Balance Sheets and Consolidated Statements of Comprehensive Income (Loss). Except for gains and losses on SERP and DCP assets, there has been no impact to the Consolidated Statements of Operations or the Consolidated Statements of Cash Flows related to these fair value measurements.

*Investment Funds* 

At June 30, 2025, Investment funds were comprised of $5.3 billion of equity securities and debt securities classified as trading measured at fair value. Equity and trading debt securities are held in the NDT, ART, SERP, DCP, and RP. The NDT holds funds for the ultimate decommissioning of TVA's nuclear power plants. The ART holds funds primarily for the costs related to the future closure and retirement of TVA's other long-lived assets. The balances in the NDT and ART were $3.5 billion and $1.6 billion, respectively, at June 30, 2025.

TVA established a SERP to provide benefits to selected employees of TVA which are comparable to those provided by competing organizations. The DCP is designed to provide participants with the ability to defer compensation to future periods.

**<u>[Ta](#i474611c3326c4e3381fecd9b884e27f6_10)[ble of Contents](#i474611c3326c4e3381fecd9b884e27f6_10)</u> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Draft 4.0&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;07/24/2025 5:00 PM**

The RP is a non-qualified excess 401(k) plan designed to allow certain eligible employees whose contributions to the 401(k) plan are limited by Internal Revenue Service ("IRS") rules to save additional amounts for retirement and receive non-elective and matching employer contributions. The NDT, ART, SERP, DCP, and RP funds are invested in portfolios of securities generally designed to achieve a return in line with overall equity and debt market performance.

The NDT, ART, SERP, DCP, and RP are composed of multiple types of investments and are managed by external institutional investment managers. Most U.S. and international equities, U.S. Treasury inflation-protected securities, and real estate investment trust securities and certain derivative instruments are measured based on quoted exchange prices in active markets and are classified as Level 1 valuations. Fixed-income investments, high-yield fixed-income investments, currencies, and most derivative instruments are non-exchange traded and are classified as Level 2 valuations. These measurements are based on market and income approaches with observable market inputs. Cash equivalents and other short-term investments are highly liquid securities with maturities of less than three months and 12 months, respectively. These consist primarily of discount securities such as repurchase agreements and U.S. Treasury bills. These securities may be priced at cost, which approximates fair value due to the short-term nature of the instruments. These securities are classified as Level 2. Active market pricing may be utilized for U.S. Treasury bills, which are classified as Level 1.

Private equity limited partnerships, private real asset investments, and private credit investments may include holdings of investments in private real estate, venture capital, buyout, mezzanine or subordinated debt, restructuring or distressed debt, and special situations through funds managed by third-party investment managers. These investments generally involve a three-to-four-year period where the investor contributes capital, followed by a period of distribution, typically over several years. The investment period is generally, at a minimum, 10 years or longer. The NDT had unfunded commitments related to private equity limited partnerships of $368 million, private real assets of $128 million, and private credit of $119 million at June 30, 2025. The ART had unfunded commitments related to limited partnerships in private equity of $143 million, private real assets of $77 million, and private credit of $58 million at June 30, 2025. These investments have no redemption or limited redemption options and may also impose restrictions on the NDT's and ART's ability to liquidate their investments. There are no readily available quoted exchange prices for these investments. The fair value of these investments is based on information provided by the investment managers. These investments are valued on a quarterly basis. Private equity limited partnerships, private real asset investments, and private credit investments are valued at net asset value ("NAV") as a practical expedient for fair value. TVA classifies its interest in these types of investments as investments measured at NAV in the fair value hierarchy.

Commingled funds represent investment funds comprising multiple individual financial instruments. The commingled funds held by the NDT, ART, SERP, DCP, and RP consist of either a single class of securities, such as equity, debt, or foreign currency securities, or multiple classes of securities. All underlying positions in these commingled funds are either exchange traded or measured using observable inputs for similar instruments. The fair value of commingled funds is based on NAV per fund share (the unit of account), derived from the prices of the underlying securities in the funds. These commingled funds can be redeemed at the measurement date NAV and are classified as Commingled funds measured at NAV in the fair value hierarchy.

Realized and unrealized gains and losses on equity and trading debt securities are recognized in current earnings and are based on average cost. The gains and losses of the NDT and ART are subsequently reclassified to a regulatory asset or liability account in accordance with TVA's regulatory accounting policy. See Note 1 — *Summary of Significant Accounting Policies* of the Notes to Consolidated Financial Statements in the Annual Report and Note 9 — *Regulatory Assets and Liabilities*. TVA recorded unrealized gains and losses related to its equity and trading debt securities held during each period as follows:

<u>Notes</u>

(1) The unrealized gains for the RP were less than $1 million for both the three and nine months ended June 30, 2025 and for both the three and nine months ended June 30, 2024, and therefore were not represented in the table above.

(2) Includes $41 million and $7 million of unrealized gains related to NDT equity securities (excluding commingled funds) for the three months ended June 30, 2025 and 2024, respectively. Includes $12 million of unrealized losses and $70 million of unrealized gains related to NDT equity securities (excluding commingled funds) for the nine months ended June 30, 2025 and 2024, respectively.

(3) Includes $10 million and $1 million of unrealized gains related to ART equity securities (excluding commingled funds) for the three months ended June 30, 2025 and 2024, respectively. Includes $5 million of unrealized losses and $24 million of unrealized gains related to ART equity securities (excluding commingled funds) for the nine months ended June 30, 2025 and 2024, respectively.

*Currency and Interest Rate Swap Derivatives*

See Note 14 — *Risk Management Activities and Derivative Transactions* — *Cash Flow Hedging Strategy for Currency Swaps* and *Derivatives Not Receiving Hedge Accounting Treatment* for a discussion of the nature, purpose, and contingent features of TVA's currency swaps and interest rate swaps. These swaps are classified as Level 2 valuations and are valued based on income approaches using observable market inputs for similar instruments.

*Commodity Contract Derivatives and Commodity Derivatives under the FHP*

*Commodity Contract Derivatives.* Most of these derivative contracts are valued based on market approaches, which utilize short-term and mid-term market-quoted prices from an external industry brokerage service. These contracts are classified as Level 2 valuations.

*Commodity Derivatives under the FHP.* Swap contracts are valued using a pricing model based on New York Mercantile Exchange inputs and are subject to nonperformance risk outside of the exit price. These contracts are classified as Level 2 valuations.

See Note 14 — *Risk Management Activities and Derivative Transactions* — *Derivatives Not Receiving Hedge Accounting Treatment* — *Commodity Derivatives* and — *Commodity Derivatives under the FHP*.

*Nonperformance Risk*

The assessment of nonperformance risk, which includes credit risk, considers changes in current market conditions, readily available information on nonperformance risk, letters of credit, collateral, other arrangements available, and the nature of master netting arrangements. TVA is a counterparty to currency swaps, interest rate swaps, commodity contracts, and other derivatives which subject TVA to nonperformance risk. Nonperformance risk on the majority of investments and certain exchange-traded instruments held by TVA is incorporated into the exit price that is derived from quoted market data that is used to mark the investment to market.

Nonperformance risk for most of TVA's derivative instruments is an adjustment to the initial asset/liability fair value. TVA adjusts for nonperformance risk, both of TVA (for liabilities) and the counterparty (for assets), by applying credit valuation adjustments ("CVAs"). TVA determines an appropriate CVA for each applicable financial instrument based on the term of the instrument and TVA's or the counterparty's credit rating as obtained from Moody's. For companies that do not have an observable credit rating, TVA uses internal analysis to assign a comparable rating to the counterparty. TVA discounts each financial instrument using the historical default rate (as reported by Moody's for CY 1983 to CY 2024) for companies with a similar credit rating over a time period consistent with the remaining term of the contract. The application of CVAs resulted in no change in the fair value of assets and a less than $3 million decrease in the fair value of liabilities at June 30, 2025.

*Fair Value Measurements*

The following tables set forth by level, within the fair value hierarchy, TVA's financial assets and liabilities that were measured at fair value on a recurring basis at June 30, 2025, and September 30, 2024. Financial assets and liabilities have been classified in their entirety based on the lowest level of input that is significant to the fair value measurement. TVA's assessment of the significance of a particular input to the fair value measurement requires judgment and may affect the determination of the fair value of the assets and liabilities and their classification in the fair value hierarchy levels.

*Other Financial Instruments Not Recorded at Fair Value*

<sup>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;</sup>

TVA uses the methods and assumptions described below to estimate the fair value of each significant class of financial instruments. The fair value of the financial instruments held at June 30, 2025, and September 30, 2024, may not be representative of the actual gains or losses that will be recorded when these instruments mature or are called or presented for early redemption. The estimated values of TVA's financial instruments not recorded at fair value at June 30, 2025, and September 30, 2024, were as follows:

The carrying values of Cash and cash equivalents, Restricted cash and cash equivalents, Accounts receivable, net, and Short-term debt, net approximate their fair values.

The fair value for loans and other long-term receivables is estimated by determining the present value of future cash flows using a discount rate equal to lending rates for similar loans made to borrowers with similar credit ratings and for similar remaining maturities, where applicable. The fair value of long-term debt and membership interests of VIEs subject to mandatory redemption is estimated by determining the present value of future cash flows using current market rates for similar obligations, giving effect to credit ratings and remaining maturities.

**16. Revenue** 

*Revenue from Sales of Electricity* 

TVA's revenue from contracts with customers is primarily derived from the generation and sale of electricity to its customers and is included in Revenue from sales of electricity on the Consolidated Statements of Operations. Electricity is sold primarily to LPCs for distribution to their end-use customers. In addition, TVA sells electricity to directly served industrial companies, federal agencies, and others.

---

| | |
|:---|:---|
| **LPC sales** | Approximately 91 percent and 92 percent of TVA's Revenue from sales of electricity for the three and nine months ended June 30, 2025, and the three and nine months ended June 30, 2024, respectively, was from LPCs, which then distribute the power to their customers using their own distribution systems. Power is delivered to each LPC at delivery points within the LPC's service territory. TVA recognizes revenue when the customer takes possession of the power at the delivery point. For power sales, the performance obligation to deliver power is satisfied in a series over time because the sales of electricity over the term of the customer contract are a series of distinct goods that are substantially the same and have the same pattern of transfer to the customer. TVA has no continuing performance obligations subsequent to delivery. Using the output method for revenue recognition provides a faithful depiction of the transfer of electricity as customers obtain control of the power and benefit from its use at delivery. Additionally, TVA has an enforceable right to consideration for energy delivered at any discrete point in time and will recognize revenue at an amount that reflects the consideration to which TVA is entitled for the energy delivered. <br>The amount of revenue is based on contractual prices approved by the TVA Board. Customers are invoiced monthly for power delivered as measured by meters located at the delivery points. The net transaction price is offset by certain credits available to customers that are known at the time of billing. Credits are designed to achieve objectives of the TVA Act and include items such as hydro preference credits for residential customers of LPCs, economic development credits to promote growth in the Tennessee Valley, wholesale bill credits to maintain long-term partnerships with LPCs, and demand response credits allowing TVA to reduce industrial customer usage in periods of peak demand to balance system demand. Payments are typically due within approximately one month of invoice issuance. |
| **Directly served customers** | Directly served customers, including industrial customers, federal agencies, and other customers, take power for their own consumption. Similar to LPCs, power is delivered to a delivery point, at which time the customer takes possession and TVA recognizes revenue. For all power sales, the performance obligation to deliver power is satisfied in a series over time since the sales of electricity over the term of the customer contract are a series of distinct goods that are substantially the same and have the same pattern of transfer to the customer. TVA has no continuing performance obligations subsequent to delivery. Using the output method for revenue recognition provides a faithful depiction of the transfer of electricity as customers obtain control of the power and benefit from its use at delivery.

*Other Revenue*

Other revenue consists primarily of wheeling and network transmission charges, sales of excess steam that is a by-product of power production, delivery point charges for interconnection points between TVA and the customer, Renewable Energy Certificate sales, and certain other ancillary goods or services.

TVA and LPCs continue to work together to meet the changing needs of consumers around the Tennessee Valley. In 2019, the TVA Board approved a partnership agreement option that better aligns the length of LPC power contracts with TVA's long-term commitments. Under the partnership arrangement, the LPC power contracts automatically renew each year and have a 20-year termination notice. The partnership arrangements can be terminated under certain circumstances, including TVA's failure to limit rate increases to no more than 10 percent during any consecutive five-fiscal-year period, as more specifically described in the agreements. Participating LPCs receive benefits including a 3.1 percent wholesale bill credit in exchange for their long-term commitment, which enables TVA to recover its long-term financial commitments over a commensurate period. The total wholesale bill credits to LPCs participating in the Partnership Agreement were $53 million and $51 million for the three months ended June 30, 2025 and 2024, respectively. The total wholesale bill credits to LPCs participating in the Partnership Agreement were $164 million and $152 million for the nine months ended June 30, 2025 and 2024, respectively. In 2020, TVA

provided participating LPCs a flexibility option, named Generation Flexibility, that allows them to locally generate or purchase up to approximately five percent of their average total hourly energy sales over a certain time period in order to meet their individual customers' needs. Revised flexibility agreements were made available to LPCs in 2023 which permit projects to be located anywhere in TVA's service area, either connected to the LPC distribution system or TVA's transmission system, and make it easier for LPCs to partner in projects. As of June 30, 2025, 148 LPCs had signed the Partnership Agreement with TVA, and 107 LPCs had signed a Power Supply Flexibility Agreement.

The number of LPCs by contract arrangement, the revenues derived from such arrangements for the three and nine months ended June 30, 2025, and the percentage those revenues comprised of TVA's total operating revenues for the same period, are summarized in the tables below:

---

---

<u>Note</u>

(1) Ordinarily, the LPCs and TVA have the same termination notice period; however, in a contract with one of the LPCs with a five-year termination notice, TVA has a 10-year termination notice (which becomes a five-year termination notice if TVA loses its discretionary wholesale rate-setting authority). Certain LPCs have five-year termination notices or a shorter period if any act of Congress, court decision, or regulatory change requires or permits that election.

Certain LPCs have five-year termination notices or a shorter period if any act of Congress, court decision, or regulatory change requires or permits that election.

TVA's two largest LPCs — Memphis Light, Gas and Water Division ("MLGW") and Nashville Electric Service ("NES") — have contracts with a five-year and a 20-year termination notice period, respectively. Sales to MLGW and NES each accounted for eight percent of TVA's total operating revenues for both the nine months ended June 30, 2025 and the nine months ended June 30, 2024.

*Contract Balances*

Contract assets represent an entity's right to consideration in exchange for goods and services that the entity has transferred to customers. TVA did not have any material contract assets at June 30, 2025.

Contract liabilities represent an entity's obligations to transfer goods or services to customers for which the entity has received consideration (or an amount of consideration is due) from the customers. These contract liabilities are primarily related to upfront consideration received prior to the satisfaction of the performance obligation. See *Economic Development Incentives* below and Note 11 — *Other Long-Term Liabilities* — *Long-Term Deferred Revenue*.

*Economic Development Incentives.* Under certain economic development programs, TVA offers incentives to existing and potential power customers in targeted business sectors that make multi-year commitments to invest in the Tennessee Valley. TVA records those incentives as reductions of revenue. Incentives recorded as a reduction to revenue were $80 million for both the three months ended June 30, 2025 and 2024. Incentives recorded as a reduction to revenue were $248 million and $233 million for the nine months ended June 30, 2025 and 2024, respectively. Incentives that have been approved but have not been paid are recorded in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. At June 30, 2025, and September 30, 2024, the outstanding unpaid incentives were $197 million and $187 million, respectively. Incentives that have been paid out may be subject to claw back if the customer fails to meet certain program requirements.

**18. Supplemental Cash Flow Information** 

Construction in progress and nuclear fuel expenditures included in Accounts payable and accrued liabilities at June 30, 2025 and 2024, were $961 million and $703 million, respectively, and are excluded from the Consolidated Statements of Cash Flows for the nine months ended June 30, 2025 and 2024 as non-cash investing activities. ARO project accruals included in Accounts payable and accrued liabilities at June 30, 2025 and 2024, were $41 million and $46 million, respectively, and are excluded from the Consolidated Statements of Cash Flows for the nine months ended June 30, 2025 and 2024, as non-cash operating activities.

Cash flows from swap contracts that are accounted for as hedges are classified in the same category as the item being

hedged or on a basis consistent with the nature of the instrument.

**19. Benefit Plans** 

TVA sponsors a pension plan that covers most of its full-time employees hired before July 1, 2014, a qualified defined contribution plan ("401(k) plan") that covers most of its full-time employees, two unfunded post-retirement health care plans that provide for non-vested contributions toward the cost of eligible retirees' medical coverage, other post-employment benefits, such as workers' compensation, the SERP, and the RP. The pension plan and the 401(k) plan are administered by a separate legal entity, the TVA Retirement System ("TVARS"), which is governed by its own board of directors.

(2) Special/contractual termination benefits for certain eligible employees related to TVA's restructuring activities. See Note 3 — *Restructuring.* 

TVA's minimum required pension plan contribution for 2025 is $300 million. TVA contributes $25 million per month to TVARS and as of June 30, 2025, had contributed $225 million. The remaining $75 million will be contributed by September 30, 2025. For the nine months ended June 30, 2025, TVA also contributed $19 million (net of $4 million in rebates) to the other post-retirement plans and $10 million to the SERP. In addition, TVA recognized 401(k) contribution costs of $95 million for the nine months ended June 30, 2025.

**20. Collaborative Arrangement**

In 2023, TVA, Ontario Power Generation, BWRX TCA sp. z.o.o., and GE Hitachi Nuclear Energy ("GEH") entered into a multi-party collaborative arrangement to advance the global deployment of the GEH BWRX-300 small modular reactor. GEH is responsible for standard design development. Under the agreement, TVA will contribute up to $93 million for design costs incurred by GEH through 2026. At the time feasibility is determined, TVA will have the right to use the design and may receive additional economic benefits.

Payments pursuant to the agreement are recorded as research and development expense, which is reflected as Operating and maintenance expense on TVA's Consolidated Statement of Operations in the period incurred. TVA recorded no expenses related to this agreement for the three months ended June 30, 2025 and $12 million of expenses for the three months ended June 30, 2024. TVA recorded $10 million and $29 million of expenses related to this agreement for the nine months ended June 30, 2025 and 2024, respectively. TVA also had a $6 million letter of credit posted under this arrangement at June 30, 2025.

 **21. Contingencies and Legal Proceedings** 

*Contingencies* 

*Nuclear Insurance*. Section 170 of the Atomic Energy Act, commonly known as the Price-Anderson Act, provides a layered framework of financial protection to compensate for liability claims of members of the public for personal injury and property damages arising from a nuclear incident in the U.S. This financial protection consists of two layers of coverage. The primary level is private insurance underwritten by American Nuclear Insurers and provides public liability insurance coverage of $500 million for each nuclear power plant licensed to operate. If this amount is not sufficient to cover claims arising from a nuclear incident, the second level, Secondary Financial Protection, applies. Within the Secondary Financial Protection level, the licensee of each nuclear reactor has a contingent obligation to pay a retrospective premium, equal to its proportionate share of the loss in excess of the primary level, regardless of proximity to the incident of fault, up to a maximum of approximately $166 million per reactor per incident. With TVA's seven reactors, the maximum total contingent obligation per incident is $1.2 billion. This retrospective premium is payable at a maximum rate currently set at approximately $25 million per year per nuclear incident per reactor. Currently, 95 reactors are participating in the Secondary Financial Protection program.

In the event that a nuclear incident results in public liability claims, the primary level provided by American Nuclear Insurers combined with the Secondary Financial Protection should provide up to $16.3 billion in coverage.

Federal law requires that each Nuclear Regulatory Commission ("NRC") power reactor licensee obtain property insurance from private sources to cover the cost of stabilizing and decontaminating a reactor and its station site after an accident. TVA carries property, decommissioning liability, and decontamination liability insurance from Nuclear Electric Insurance Limited ("NEIL") and European Mutual Association for Nuclear Insurance. The limits available for a loss are up to $2.1 billion for two of TVA's nuclear sites and up to $2.8 billion for the remaining site. Some of this insurance may require the payment of retrospective premiums up to a maximum of approximately $122 million.

TVA purchases accidental outage (business interruption) insurance for TVA's nuclear sites from NEIL. In the event that an accident covered by this policy takes a nuclear unit offline or keeps a nuclear unit offline, NEIL will pay TVA, after a waiting period, an indemnity (a set dollar amount per week) with a maximum indemnity of $490 million per unit. This insurance policy may require the payment of retrospective premiums up to a maximum of approximately $50 million, but only to the extent the retrospective premium is deemed necessary by the NEIL Board of Directors to pay losses unable to be covered by NEIL's surplus.

*Decommissioning Costs.* TVA recognizes legal obligations associated with the future retirement of certain tangible long-lived assets related primarily to nuclear generating plants, coal-fired generating plants, hydroelectric generating plants/dams, transmission structures, and other property-related assets. See Note 12 — *Asset Retirement Obligations*.

<u>Nuclear Decommissioning</u>. Provision for decommissioning costs of nuclear generating units is based on options authorized by the NRC procedures to dismantle and decontaminate the facilities to meet the NRC criteria for license termination. At June 30, 2025, $3.9 billion, representing the discounted value of future estimated nuclear decommissioning costs, was included in nuclear AROs. The actual decommissioning costs may vary from the derived estimates because of, among other things, changes in current assumptions, such as the assumed dates of decommissioning, changes in regulatory requirements, changes in technology, and changes in the cost of labor, materials, and equipment. Utilities that own and operate nuclear plants are required to use different procedures in calculating nuclear decommissioning costs under GAAP than those that are used in calculating nuclear decommissioning costs when reporting to the NRC. The two sets of procedures produce different estimates for the costs of decommissioning primarily because of differences in the underlying assumptions. TVA bases its nuclear decommissioning estimates on site-specific cost studies. The most recent study was approved and implemented in September 2022. Site-specific cost studies are updated for each of TVA's nuclear units at least every five years.

TVA maintains an NDT to provide funding for the ultimate decommissioning of its nuclear power plants. See Note 15 — *Fair Value Measurements* — *Investment Funds*. TVA monitors the value of its NDT and believes that, over the long term and before cessation of nuclear plant operations and commencement of decommissioning activities, adequate funds from investments and additional contributions, if necessary, will be available to support decommissioning. TVA's operating nuclear power units are licensed through various dates between 2033 - 2055, depending on the unit. It may be possible to extend the operating life of some of the units with approval from the NRC. See Note 9 — *Regulatory Assets and Liabilities* and Note 12 — *Asset Retirement Obligations*.

<u>Non-nuclear Decommissioning</u>. At June 30, 2025, $7.0 billion, representing the discounted value of future estimated non-nuclear decommissioning costs, was included in non-nuclear AROs. This decommissioning cost estimate involves estimating the amount and timing of future expenditures and making judgments concerning whether or not such costs are considered a legal obligation. Estimating the amount and timing of future expenditures includes, among other things, making projections of the timing and duration of the asset retirement process and how costs will escalate with inflation. The actual decommissioning costs may vary from the derived estimates because of changes in current assumptions, such as the assumed dates of decommissioning, changes in regulatory requirements, changes in technology, and changes in the cost of labor, materials, and equipment. TVA updates its underlying assumptions for non-nuclear decommissioning AROs at least every five years. However, material changes in underlying assumptions that impact the amount and timing of undiscounted cash flows are continuously monitored and incorporated into ARO balances in the period identified.

TVA maintains an ART to help fund the ultimate decommissioning of its non-nuclear power assets. See Note 15 — *Fair Value Measurements* — *Investment Funds*. Estimates involved in determining if additional funding will be made to the ART include inflation rate, rate of return projections on the fund investments, and the planned use of other sources to fund decommissioning costs. See Note 9 — *Regulatory Assets and Liabilities* and Note 12 — *Asset Retirement Obligations*.

*Environmental Matters.* TVA's generation activities, like those across the utility industry and in other industrial sectors, are subject to federal, state, and local environmental laws and regulations. Major areas of regulation affecting TVA's activities include air quality control, greenhouse gas ("GHG") emissions, water quality control, and management and disposal of solid and hazardous wastes. Regulations in these major areas have become more stringent in recent years and have had a particular emphasis on climate change, renewable generation, and energy efficiency.

TVA has incurred, and expects to continue to incur, substantial capital and operating and maintenance costs to comply with evolving environmental requirements primarily associated with, but not limited to, the operation of TVA's coal-fired and natural gas-fired generating units in general and emissions of pollutants from those units. Failure to comply with environmental and safety requirements can result in enforcement actions and litigation, which can lead to the imposition of significant civil liability, including fines and penalties, criminal sanctions, and/or temporary or permanent closure of non-compliant facilities*.* Historical non-compliance can also lead to difficulty in renewing existing permits, as well as difficulty in obtaining permits to bring new generation facilities online. Other obstacles to renewal or permitting of new facilities include a proliferation of non-government organizations seeking to use litigation tools to drive up costs associated with, and delay or prevent permitting of, new fossil fuel facilities and related infrastructure in favor of renewable energy projects.

Compliance with the Environmental Protection Agency's ("EPA") 2015 CCR Rule, as revised ("2015 CCR Rule") required implementation of a groundwater monitoring program, additional engineering, evaluation of authorized closure methods, coordination with certain state authorities, and ongoing analysis at each TVA CCR unit. As further analyses are performed, including evaluation of monitoring results, there is the potential for additional costs for investigation and/or remediation. In addition, on May 8, 2024, EPA published its Legacy CCR Rule, which expands the scope of the existing regulatory requirements of the 2015 CCR Rule to include two additional classes of CCR units: Legacy Surface Impoundments and Coal Combustion Residual Management Units. As a result of the enactment of the final rule, during 2024, TVA recorded additional estimated AROs and recorded a corresponding regulatory asset due to AROs being associated with closed sites and asset retirement costs having been fully depreciated. However, the amounts recorded are subject to various uncertainties, and actual amounts may differ materially based upon a number of factors, including, but not limited to, the outcome of legal challenges to the Legacy CCR Rule, ongoing evaluations of the number and scope of newly regulated units, determinations on final closure requirements and performance standards, and possible changes to the Legacy CCR Rule by EPA.

In May 2024, EPA also published (1) a final rule that establishes more stringent technology-based effluent limitations for four wastewater streams from coal-fired plants, (2) a rule that strengthens and updates the Mercury and Air Toxics Standards for electric generating units to reflect recent developments in control technologies, and (3) a rule that establishes GHG emission guidelines for existing coal-fired plants and GHG performance standards for new natural gas-fired power plants. These rules are all currently being reconsidered by EPA and are also all subject to legal challenges. If these rules move forward as written and the challenges are not successful, TVA would incur substantial costs to comply with the rules.

On March 12, 2025, the EPA Administrator announced that EPA will reconsider 31 rules, including (1) regulations on power plants, (2) Mercury and Air Toxics Standards, (3) steam electric effluent limitation guidelines, (4) National Ambient Air Quality Standards for particulate matter, (5) regulations regarding regional haze, (6) the Good Neighbor Plan, and (7) CCR regulations. TVA cannot predict the outcome of such reevaluations or their impact on TVA's financial results or operations. See Part I, Item 1, Business — *Environmental Matters* in the Annual Report.

Liability for releases, natural resource damages, and required cleanup of hazardous substances is primarily regulated by the federal Comprehensive Environmental Response, Compensation, and Liability Act ("CERCLA"), the Resource Conservation and Recovery Act ("RCRA"), and other federal and parallel state statutes. In a manner similar to many other governmental entities, industries, and power systems, TVA has generated or used hazardous substances over the years. TVA operations at some facilities have resulted in releases of contaminants that TVA has addressed or is addressing consistent with state and federal requirements. At June 30, 2025, and September 30, 2024, TVA's estimated liability for required cleanup and similar environmental work for those sites for which sufficient information is available to develop a cost estimate was $10 million and $15 million, respectively, on a non-discounted basis, and was included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. Additionally, the potential inclusion of new hazardous substances under CERCLA and RCRA jurisdiction could significantly affect TVA's future liability for remediating historical releases.

In August 2015, the Tennessee Department of Environment and Conservation ("TDEC") issued an order that includes an iterative process through which TVA and TDEC will identify and evaluate any CCR contamination risks and, if necessary, respond to such risks. TVA is also following a similar process pursuant to a consent order. At June 30, 2025, and September 30, 2024, TVA's estimated liability for costs associated with environmental remediation activities for the sites covered by these orders for which sufficient information is available to develop a cost estimate was approximately $313 million and $215 million, respectively, on a non-discounted basis and was included in Accounts payable and accrued liabilities and Other long-term liabilities on the Consolidated Balance Sheets. The current estimated time frame for work related to these remediation activities for which TVA has a cost estimate is through 2044.

*Legal Proceedings* 

From time to time, TVA is party to or otherwise involved in lawsuits, claims, proceedings, investigations, and other legal matters ("Legal Proceedings") that have arisen in the ordinary course of conducting TVA's activities. There have been no material changes to the Legal Proceedings described in Note 22 — *Commitments and Contingencies* — *Legal Proceedings* of the Annual Report, except as described below.

*Case Involving Johnsonville Aeroderivative Combustion Turbine Project.* On December 22, 2022, the Southern Environmental Law Center filed a lawsuit in the U.S. District Court for the Middle District of Tennessee on behalf of the Sierra Club, alleging that TVA violated the National Environmental Policy Act ("NEPA") in deciding to build a new aeroderivative combustion turbine project at its Johnsonville facility. Both parties moved for summary judgment, and on September 30, 2024, the court granted TVA's motion for summary judgment and dismissed the lawsuit. The Sierra Club did not file an appeal within 60 days from the date of the decision, so this litigation has now ended. See Note 22 — *Commitments and Contingencies* — *Legal Proceedings — Case Involving Johnsonville Aeroderivative Combustion Turbine Project* in the Annual Report.

*Case Involving Kingston Gas-Fired Plant.* On October 10, 2024, Appalachian Voices, the Center for Biological Diversity, and the Sierra Club filed a lawsuit in the U.S. District Court for the Eastern District of Tennessee alleging that TVA violated NEPA and TVA's least-cost planning obligations in deciding to build a gas plant at its Kingston Facility. TVA filed its answer on December 16, 2024. The plaintiffs filed a motion to compete the administrative record on June 30, 2025. TVA cannot predict the outcome of this litigation. See Note 22 — *Commitments and Contingencies* — *Legal Proceedings* — *Case Involving Kingston Gas-Fired Plant* in the Annual Report.

*Challenge to Kingston Construction Permit.* On December 16, 2024, the Southern Environmental Law Center filed an appeal on behalf of Appalachian Voices challenging the construction permit that the Technical Secretary acting on behalf of the Tennessee Air Pollution Control Board issued to TVA on November 15, 2024, for the construction of natural gas generation at Kingston. Appalachian Voices alleges that TDEC unlawfully issued a construction permit that would allow TVA to construct the plant without meeting the requirements set forth in the Tennessee Air Quality Act's and Federal Clean Air Act's Prevention of Significant Deterioration program. Among other things, Appalachian Voices is requesting that the Tennessee Air Pollution Control Board stay the effectiveness of the permit and order TDEC to revoke the permit. On January 7, 2025, TVA filed a petition to intervene in the administrative proceeding, which was granted on January 15, 2025. The parties filed competing motions for summary judgement on March 14, 2025, and oral argument on these motions was held on June 24, 2025. TVA cannot predict the outcome of this litigation.

*Challenge to Certificate for Cumberland Pipeline.* On April 29, 2024, the Southern Environmental Law Center, on behalf of the Sierra Club and Appalachian Voices, filed a petition with the United States Court of Appeals for the District of Columbia Circuit ("D.C. Circuit") challenging the Federal Energy Regulatory Commission's ("FERC's") issuance of a certificate of public convenience for the pipeline that will need to be constructed in order for TVA to operate the Cumberland Combined Cycle Plant (the "Cumberland Pipeline"). The petitioners allege that they and their members have been and will be aggrieved by the approval, construction, and operation of the Cumberland Pipeline and are asking the D.C. Circuit to review and set aside FERC's order approving the pipeline. The D.C. Circuit heard oral arguments on the merits on March 4, 2025, but has not yet issued a ruling. TVA, the Tennessee Valley Public Power Association, and Tennessee Gas Pipeline Company, L.L.C., which has contracted with TVA to build and operate the pipeline, have intervened in the proceeding. TVA cannot predict the outcome of this litigation.

**ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

The Management's Discussion and Analysis of Financial Condition and Results of Operations ("MD&A") explains the results of operations and general financial condition of the Tennessee Valley Authority ("TVA"). The MD&A should be read in conjunction with the accompanying unaudited consolidated financial statements and TVA's Annual Report on Form 10-K for the year ended September 30, 2024 (the "Annual Report").

**Executive Overview**

TVA's operating revenues were $9.8 billion and $8.8 billion for the nine months ended June 30, 2025 and 2024, respectively. Operating revenues increased for the nine months ended June 30, 2025, as compared to the same period of the prior year, primarily as a result of higher effective fuel rates, higher effective base rates, and increased sales volume. Higher effective fuel rates were due primarily to using higher cost coal and natural gas generation due to less availability of nuclear generation as compared to the same period of the prior year. Effective base rates were higher primarily due to the TVA Board of Directors ("TVA Board") action to approve a 5.25 percent wholesale base rate increase effective October 1, 2024. The increased sales volume was primarily driven by higher sales to residential and small commercial and industrial customers as well as increases within the data processing, hosting, and related services sector, partially offset by a decrease in cooling degree days.

Total operating expenses increased $743 million for the nine months ended June 30, 2025, as compared to the nine months ended June 30, 2024. Fuel and purchased power expense increased $490 million for the nine months ended June 30, 2025, as compared to the same period of the prior year, primarily due to higher demand for purchased power as a result of less availability of nuclear generation and higher effective fuel rates. There was a $100 million increase in Operating and maintenance expense primarily due to increases in payroll and benefit costs related to severance costs associated with Enterprise Transformation Program ("ETP") efforts and labor escalation for cost of living increases and an increase in nuclear outage days. In addition, Depreciation and amortization expense increased $98 million primarily as a result of increases in the amortization expense of finance leases and amortization expense of decommissioning costs recovered in rates, the decision to retire Kingston Fossil Plant ("Kingston"), and additions to net completed plant.

Pre-commercial plant operations began on Johnsonville Aeroderivative combustion turbine ("CT") Units 25-28 in the first quarter of 2025 and began on Units 21-24 and 29-30 in the second quarter of 2025. Units 21-25 and 27-30 became operational on May 6, 2025.

On January 22, 2025, TVA reached an all-time record high peak power demand of approximately 35,430 megawatts ("MW"). This peak was over 800 MW greater than TVA's previous all-time peak set in January 2024.

**Results of Operations** 

*Sales of Electricity*

Sales of electricity were 39,751 million and 39,342 million kilowatt hours ("kWh") for the three months ended June 30, 2025 and 2024, respectively. Sales of electricity were 120,527 million and 117,313 million kWh for the nine months ended June 30, 2025 and 2024, respectively. The total sales of electricity during the nine months ended June 30, 2025 included 94 thousand kWh of pre-commercial generation at Johnsonville Aeroderivative CT Units 21-30, of which 35 thousand kWh was recognized in the three months ended June 30, 2025. The total sales of electricity during the nine months ended June 30, 2024 included 137 thousand kWh of pre-commercial generation at Paradise CT Units 5-7, all of which was recognized in the three months ended December 31, 2023. TVA sells power at wholesale rates to local power company customers ("LPCs") that then resell the power to their customers at retail rates. TVA also sells power to directly served customers, consisting primarily of federal agencies and customers with large or nonstandard loads. In addition, power exceeding TVA's system needs is sold under exchange power arrangements with certain other power systems.

The following charts compare TVA's sales of electricity by customer type for the periods indicated:

Sales of electricity increased one percent for the three months ended June 30, 2025, as compared to the same period of the prior year. The increased sales volume was primarily driven by higher sales to residential and small commercial and industrial customers as well as increases within the data processing, hosting, and related services sector. Partially offsetting the increased sales volume was a 12.5 percent decrease in cooling degree days compared to the same period of the prior year.

Sales of electricity increased three percent for the nine months ended June 30, 2025, as compared to the same period of the prior year. The increased sales volume was primarily driven by higher sales to residential and small commercial and industrial customers as well as increases within the data processing, hosting, and related services sector. Partially offsetting the increased sales volume was an 8.2 percent decrease in cooling degree days compared to the same period of the prior year.

<u>Note</u>

(1) Represents revenue capitalized during pre-commercial operations at Johnsonville Aeroderivative CT Units 21-30 in the three and nine months ended June 30, 2025 and Paradise CT Units 5-7 in the nine months ended June 30, 2024, all of which was recognized in the three months ended December 31, 2023.

TVA's two largest LPCs — Memphis Light, Gas and Water Division ("MLGW") and Nashville Electric Service ("NES") — have contracts with a five-year and a 20-year termination notice period, respectively. Sales to both MLGW and NES accounted for eight percent of TVA's total operating revenues for both the nine months ended June 30, 2025 and the nine months ended June 30, 2024.

TVA's rate structure uses pricing signals to indicate seasons and hours of higher cost to serve its customers and to capture a portion of TVA's fixed costs in fixed charges. The structure includes three base revenue components: time of use demand charges, time of use energy charges, and a grid access charge ("GAC"). The demand charges are based upon the customer's peak monthly usage. The energy charges are based on time differentiated kWh used by the customer. Both of these components can be significantly impacted by weather. The GAC captures a portion of fixed costs and is offset by a corresponding reduction to the energy rates. The GAC also reduces the impact of weather variability to the overall rate structure.

&nbsp;&nbsp;&nbsp;&nbsp;

TVA has a Partnership Agreement option that better aligns the length of LPC power contracts with TVA's long-term commitments. Under the partnership arrangement, the LPC power contracts automatically renew each year and have a 20-year termination notice. The partnership arrangements can be terminated under certain circumstances, including TVA's failure to limit rate increases to no more than 10 percent during any consecutive five-fiscal-year period, as more specifically described in the

agreements. Participating LPCs receive benefits including a 3.1 percent wholesale bill credit in exchange for their long-term commitment, which enables TVA to recover its long-term financial commitments over a commensurate period. As of June 30, 2025, 148 LPCs had signed the 20-year Partnership Agreement with TVA.

&nbsp;&nbsp;&nbsp;&nbsp;

In addition to base revenues, the rate structure includes a separate fuel rate that includes the costs of natural gas, fuel oil, purchased power, coal, emission allowances, nuclear fuel, and other fuel-related commodities; realized gains and losses on derivatives purchased to hedge the costs of such commodities; and payments to states and counties in lieu of taxes ("tax equivalents") associated with the fuel cost adjustments.

TVA is required to charge rates for power that will produce gross revenues sufficient to cover various costs as discussed in Part I, Item I, Business — *Rates* of the Annual Report. In August 2024, the TVA Board approved a 5.25 percent wholesale base rate increase (excluding fuel) effective October 1, 2024, primarily due to additional capacity needs and rising costs. This rate adjustment is estimated to produce an additional $495 million of revenue during 2025.

(2) Represents revenue capitalized during pre-commercial operations at Johnsonville Aeroderivative CT Units 21-30 in the three and nine months ended June 30, 2025 and Paradise CT Units 5-7 in the nine months ended June 30, 2024, all of which was recognized in the three months ended December 31, 2023.

&nbsp;&nbsp;&nbsp;&nbsp;

Operating revenues increased $427 million for the three months ended June 30, 2025, as compared to the same period of the prior year, primarily due to a $302 million increase in fuel cost recovery revenue. The $302 million increase in fuel cost recovery revenue was driven by a $296 million increase attributable to higher effective fuel rates and a $6 million increase attributable to higher sales volume. The higher effective fuel rates were due primarily to using higher cost coal and natural gas generation due to less availability of nuclear generation as compared to the same period of the prior year. In addition, there was a $130 million increase in base revenue driven by a $104 million increase attributable to higher effective base rates and a $26 million increase attributable to higher sales volume. The increase in effective base rates was primarily due to the TVA Board action to approve a 5.25 percent wholesale base rate increase effective October 1, 2024. The higher sales volume was driven primarily by higher sales to residential and small commercial and industrial customers as well as increases within the data processing, hosting, and related services sector, partially offset by a decrease in cooling degree days.

Operating revenues increased $960 million for the nine months ended June 30, 2025, as compared to the same

period of the prior year, primarily due to a $492 million increase in base revenue. The $492 million increase in base revenue was driven by a $262 million increase attributable to higher effective base rates and a $230 million increase attributable to higher sales volume. The increase in effective base rates was primarily due to the TVA Board action to approve a 5.25 percent wholesale base rate increase effective October 1, 2024. The higher sales volume was driven primarily by higher sales to residential and small commercial and industrial customers as well as increases within the data processing, hosting, and related services sector, partially offset by a decrease in cooling degree days. In addition, there was a $469 million increase in fuel cost recovery revenue driven by a $401 million increase attributable to higher effective fuel rates and a $68 million increase attributable to higher sales volume. The higher effective fuel rates were due primarily to using higher cost coal and natural gas generation due to less availability of nuclear generation as compared to the same period of the prior year.

*Three Months Ended June 30, 2025, Compared to Three Months Ended June 30, 2024*

Fuel expense increased $165 million for the three months ended June 30, 2025, as compared to the same period of the prior year. This increase was primarily driven by an increase in fuel cost recovery of $127 million due to the collection of significant fuel costs from the previous quarter that were the result of higher than expected coal and natural gas prices due to colder than average temperatures. Additionally, fuel expense increased $53 million primarily due to higher effective fuel rates related to using higher cost coal and natural gas generation due to less availability of nuclear generation as compared to the same period of the prior year. Partially offsetting this increase was a decrease of $15 million due to less availability of nuclear generation and more availability of hydro generation as compared to the same period of the prior year.

Purchased power expense increased $142 million for the three months ended June 30, 2025, as compared to the same period of the prior year. This increase was primarily due to an increase of $82 million from higher purchased power market prices compared to the same period of the prior year. Additionally, purchased power expense increased $52 million due to higher demand for energy with less availability of TVA nuclear generation. Purchased power expense also increased $8 million

due to the recovery of purchased power costs from the previous quarter that were the result of higher than expected purchased power prices due to colder than average temperatures.

Operating and maintenance expense increased $7 million for the three months ended June 30, 2025, as compared to the same period of the prior year. This increase was primarily due to a $19 million increase in outage expense primarily due to an increase in nuclear outage days.

Depreciation and amortization expense increased $30 million for the three months ended June 30, 2025, as compared to the same period of the prior year. The increase was primarily driven by a $9 million increase in amortization expense of finance leases and amortization expense of decommissioning costs recovered in rates, as well as an increase due to depreciation of additions to net completed plant.

Tax equivalents expense increased $25 million for the three months ended June 30, 2025, as compared to the same period of the prior year. This change is primarily driven by an increase in TVA's revenue from sales of electricity in 2024, which is used as the basis for calculating tax equivalent expense.

*Nine Months Ended June 30, 2025, Compared to Nine Months Ended June 30, 2024*

Fuel expense increased $113 million for the nine months ended June 30, 2025, as compared to the same period of the prior year. An increase of $192 million was due primarily to higher effective fuel rates related to using higher cost coal and natural gas generation due to less availability of nuclear generation as compared to the same period of the prior year. Partially offsetting this increase was a decrease of $42 million due to less availability of nuclear generation and more availability of hydro generation as compared to the same period of the prior year. Additionally, fuel expense decreased $37 million related to the deferral of unplanned coal and gas costs due to less availability of nuclear generation.

Purchased power expense increased $377 million for the nine months ended June 30, 2025, as compared to the same period of the prior year. This increase was primarily due to higher demand for energy and less availability of TVA nuclear generation, resulting in an increase of $358 million.

Operating and maintenance expense increased $100 million for the nine months ended June 30, 2025, as compared to the same period of the prior year. This increase was primarily due to $113 million of increased payroll and benefit costs primarily due to severance costs associated with ETP efforts and labor escalation for cost of living increases. In addition, there was a $36 million increase in outage expense primarily due to an increase in nuclear outage days. Partially offsetting these increases was a $27 million decrease in expenditures related to project contract labor primarily due to higher power operations performance activities and other natural gas project work in the prior year.

Depreciation and amortization expense increased $98 million for the nine months ended June 30, 2025, as compared to the same period of the prior year. The increase was primarily driven by an increase of $33 million related to amortization expense of finance leases and amortization expense of decommissioning costs recovered in rates and an increase in depreciation expense of $18 million related to the decision in April 2024 to retire Kingston. Additionally, there was an increase due to depreciation of additions to net completed plant.

Tax equivalents expense increased $55 million for the nine months ended June 30, 2025, as compared to the same period of the prior year. This change is primarily driven by an increase in TVA's revenue from sales of electricity in 2024, which is used as the basis for calculating tax equivalent expense.

<u>Notes</u>

(1) Includes amortization of debt discounts, issuance, and reacquisition costs, net.

(2) Includes average balances of long-term power bonds, debt of variable interest entities ("VIEs"), and discount notes.

(3) Includes interest on long-term power bonds, debt of VIE, and discount notes.

Total interest expense increased $40 million for the three months ended June 30, 2025, as compared to the same period of the prior year. This increase was primarily driven by a $32 million increase from higher average balances and rates on long-term debt, and a $17 million increase in interest on other financing leases, primarily the new lease financing arrangement with Johnsonville Aeroderivative Combustion Turbine Generation LLC ("JACTG"). This increase was partially offset by a $9 million decrease in interest on short-term debt primarily due to lower average balances and rates.

Total interest expense increased $85 million for the nine months ended June 30, 2025, as compared to the same period of the prior year. This increase was primarily driven by a $54 million increase from higher average balances and rates on long-term debt, and a $41 million increase in interest on other financing leases, primarily the new lease financing arrangement with JACTG. This increase was partially offset by a $10 million decrease in interest on short-term debt primarily due to lower average balances and rates.

**Liquidity and Capital Resources** 

*Sources of Liquidity*

TVA depends on various sources of liquidity to meet cash needs and contingencies. TVA's primary sources of liquidity are cash from operations and proceeds from the issuance of short-term debt in the form of discount notes, along with periodic issuances of long-term debt. TVA's balance of short-term debt typically changes frequently as TVA issues discount notes to meet short-term cash needs and pay scheduled maturities of discount notes and long-term debt. TVA's next significant power bond maturity is $1.4 billion in November 2025. The periodic amounts of short-term debt issued are determined by near-term expectations for cash receipts, cash expenditures, and funding needs, while seeking to maintain a target range of cash and cash equivalents on hand. TVA may hold higher cash balances from time to time in response to potential market volatility or other business conditions. In addition, cash balances may include collateral received from counterparties.

In addition to cash from operations and proceeds from the issuance of short-term and long-term debt, TVA's sources of liquidity include four revolving credit facilities totaling $2.7 billion, a $150 million credit facility with the United States Department of the Treasury ("U.S. Treasury"), and proceeds from other financings. See Note 13 *— Debt and Other Obligations* — *Credit Facility Agreements.* The TVA Board authorized TVA to issue power bonds and enter into other financing arrangements in an aggregate amount not to exceed $4.0 billion during 2025. In the second quarter of 2025, TVA issued $1.25 billion of power bonds maturing in February 2055. In the third quarter of 2025, TVA issued $1.5 billion of power bonds maturing in May 2035. Other financing arrangements may include, but are not limited to, lease financings, energy prepayments from customers, and other similar agreements. TVA may also engage in other alternative forms of financing such as sales of receivables, or loans, from time to time.

The Tennessee Valley Authority Act of 1933, as amended ("TVA Act"), authorizes TVA to issue bonds, notes, or other evidences of indebtedness (collectively, "Bonds") in an amount not to exceed $30.0 billion outstanding at any time. Bonds outstanding, excluding unamortized discounts and premiums and net exchange gains from foreign currency transactions, at June 30, 2025, were $21.1 billion (including current maturities). The balance of Bonds outstanding directly affects TVA's capacity to meet operational liquidity needs and to strategically use Bonds to fund certain capital investments as management and the TVA Board may deem desirable. Other options for financing not subject to the limit on Bonds, including lease financings, could provide supplementary funding if needed. Currently, TVA expects to utilize a combination of Bonds, other financings, and

potentially additional power revenues through power rate increases to meet its ongoing operational liquidity needs while making planned capital investments through the decade. TVA may also utilize available funding through the Inflation Reduction Act of 2022 ("IRA") and the Bipartisan Infrastructure Law ("BIL"), other federal funding opportunities, or other third-party financing arrangements. See *Lease Financings* below, *Key Initiatives and Challenges* — *Executive Actions,* Note 10 *— Variable Interest Entities*, and Note 13 *— Debt and Other Obligations* for additional information.

TVA may from time to time seek to retire or purchase its outstanding debt through cash purchases and/or exchanges for securities, in open market purchases, privately negotiated transactions, or otherwise. Such repurchases or exchanges, if any, will depend on prevailing market conditions, TVA's liquidity requirements, contractual restrictions, and other factors. The amounts involved may be material.

*Debt Securities*. TVA's Bonds are not obligations of the U.S., and the U.S. does not guarantee the payments of principal or interest on Bonds. TVA's Bonds consist of power bonds and discount notes. Power bonds have maturities of between one and 50 years. At June 30, 2025, the average maturity of long-term power bonds was 14.62 years, and the weighted average interest rate was 4.92 percent. Discount notes have maturities of less than one year. Power bonds and discount notes have a first priority and equal claim of payment out of net power proceeds. Net power proceeds are defined as the remainder of TVA's gross power revenues after deducting the costs of operating, maintaining, and administering its power properties and tax equivalents, but before deducting depreciation accruals or other charges representing the amortization of capital expenditures, plus the net proceeds from the sale or other disposition of any power facility or interest therein. In addition to power bonds and discount notes, TVA had long-term debt associated with certain VIEs outstanding at June 30, 2025. See *Lease Financings* below, Note 10 *— Variable Interest Entities*, and Note 13 *— Debt and Other Obligations* for additional information.

TVA's rated senior unsecured Bonds are currently rated Aa1, AA+, and AA+, by Moody's Investors Service, Inc. ("Moody's"), Fitch Ratings, Inc. ("Fitch"), and S&P Global Ratings ("S&P"), respectively. TVA's short-term discount notes are not rated. TVA and the owners of TVA securities could be impacted by any downgrades of TVA's credit ratings. TVA Bonds are not obligations of the U.S.; however, because TVA is a wholly-owned corporate agency and instrumentality of the U.S. government, TVA's ratings may be impacted if the sovereign credit ratings of the U.S. are downgraded. On November 10, 2023, Moody's revised the outlook on the U.S. government's credit ratings from stable to negative, and subsequently determined on November 13, 2023, to revise the outlook on TVA's ratings from stable to negative due to the change in the government rating outlook. On May 16, 2025, Moody's downgraded the U.S. government's credit rating from Aaa to Aa1, and on May 19, 2025, Moody's subsequently downgraded TVA's rating from Aaa to Aa1, and the outlook was revised to stable. TVA was not required to post additional collateral due to the downgrade. The outlook on the ratings of TVA is also currently stable with Fitch and S&P. See Part I, Item 1A, Risk Factors *— Financial, Economic, and Market Risks — TVA, together with owners of TVA securities, may be impacted by downgrades of TVA's credit ratings* in the Annual Report.

*Lease Financings*. TVA has entered into certain leasing transactions with special purpose entities ("SPEs") to obtain third-party financing for its facilities. These SPEs are sometimes identified as VIEs of which TVA is determined to be the primary beneficiary. TVA is required to account for these VIEs on a consolidated basis. See Note 10 — *Variable Interest Entities*.

*Summary Cash Flows* 

A major source of TVA's liquidity is operating cash flows resulting from the generation and sale of electricity. Cash, cash equivalents, and restricted cash totaled $522 million and $521 million at June 30, 2025 and 2024, respectively. A summary of cash flow components for the nine months ended June 30, 2025 and 2024, follows:

&nbsp;&nbsp;&nbsp;&nbsp;Cash provided by (used in):

![5430](tve-20250630_g10.jpg)![5431](tve-20250630_g11.jpg)![5432](tve-20250630_g12.jpg)

*Operating Activities*. TVA's cash flows from operations are primarily driven by sales of electricity, fuel expense, and operating and maintenance expense. The timing and level of cash flows from operations can be affected by the weather, changes in working capital, commodity price fluctuations, outages, and other project expenses.

Net cash flows provided by operating activities increased $137 million for the nine months ended June 30, 2025, as compared to the same period of the prior year. The increase was primarily due to higher revenue collections. Revenue collections increased primarily due to the increase in the 2025 wholesale base rate in addition to higher sales volume and higher effective fuel rates. This increase was partially offset by higher payroll and benefit-related payments in addition to higher fuel and purchased power payments as compared to the same period of the prior year.

&nbsp;&nbsp;&nbsp;&nbsp;

*Investing Activiti*es. The majority of TVA's investing cash flows are due to investments to acquire, upgrade, or maintain generating and transmission assets, including environmental projects and the purchase of nuclear fuel.

Net cash flows used in investing activities increased $1.1 billion for the nine months ended June 30, 2025, as compared to the same period of the prior year, driven by increased expenditures for capacity expansion projects, primarily related to natural gas plant builds and upgrades to the nuclear fleet.

*Financing Activities*. TVA's cash flows provided by or used in financing activities are primarily driven by the timing and level of cash flows provided by operating activities, cash flows used in investing activities, and net issuance and redemption of debt instruments to maintain a strategic balance of cash on hand.

Net cash provided by financing activities increased $944 million for the nine months ended June 30, 2025, as compared to the same period of the prior year, primarily due to higher debt issuances and proceeds from debt of variable interest entities. Higher net cash flows provided by operating activities were offset by higher net cash used in investing activities which resulted in the need for net debt issuances to maintain targeted cash balance levels during the period. TVA anticipates a need to increase debt in the coming years as it continues to invest in power system assets, which may result in positive net cash flows provided by financing activities in future periods.

*&nbsp;&nbsp;&nbsp;&nbsp;Contractual Obligations*

TVA has certain obligations and commitments to make future payments under contracts. TVA's contractual obligations are discussed in the Annual Report in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Liquidity and Capital Resources*, Note 8 — *Leases,* Note 10 — *Variable Interest Entities*, Note 14 — *Debt and Other Obligations*, Note 20 — *Benefit Plans*, and Note 22 — *Commitments and Contingencies*.

&nbsp;&nbsp;&nbsp;&nbsp;During the nine months ended June 30, 2025, TVA's fuel purchase obligations increased $862 million primarily due to new and/or extended contracts for natural gas, natural gas storage, coal, and nuclear fuel. Natural gas commitments increased $145 million as a result of entering into multiple natural gas contracts with new commitments from 2025 to 2035, of which $120 million is estimated to be paid during the remainder of 2025. Natural gas storage commitments increased $285 million as a result of entering into three new contracts and extending three contracts, which increased commitments from 2025 through 2034, of which $7 million is estimated to be paid during the remainder of 2025. Coal commitments increased by $369 million due primarily to entering into three new coal contracts with new commitments from 2025 through 2029, of which $64 million is estimated to be paid during the remainder of 2025. Nuclear fuel commitments increased $118 million due primarily to three new

nuclear fuel contracts with new commitments from 2028 through 2035. In addition, TVA entered into a new power purchase agreement ("PPA") totaling $293 million with commitments from 2025 to 2028, of which $23 million is estimated to be paid during the remainder of 2025, and three new long-term service agreements totaling $200 million with commitments from 2025 to 2045, of which less than $1 million is estimated to be paid during the remainder of 2025.

**Key Initiatives and Challenges** 

There have been no material changes to the key initiatives and challenges described in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations *— Key Initiatives and Challenges* of the Annual Report, except as described below.

*Cost Reduction Initiatives*

TVA's demand continues to grow, driving the need for significant capital investments in its power system. TVA must continue to drive efficiencies and cost savings across the enterprise to provide low-cost, reliable power, while funding the capital investment needed to meet growing demand. TVA has undertaken a cost optimization initiative designed to reduce planned cost increases by approximately $950 million during the three-year period from 2024 to 2026. TVA met its reduction target for 2024 and has plans to meet the targets set for 2025 and 2026. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Optimum Energy Portfolio* in the Annual Report.

This effort has evolved into an Enterprise Transformation Program ("ETP") designed to enable TVA to deliver at least $500 million of sustainable reductions to planned cost increases in 2026 and beyond to support future fleet investments needed to meet growing demand. TVA's ETP is focused on improving financial health, enhancing asset performance, automating processes, optimizing third-party spend through supply chain, and making the workforce more efficient. As part of these efforts, certain employees will be eligible for severance payments. As of June 30, 2025, TVA had accrued $14 million related to estimated future severance payments. The ETP is ongoing, and any potential future severances costs are uncertain at this time.

*Optimum Energy Portfolio*

Additional load growth for the foreseeable future is expected, and new capacity will be needed to support this load growth and replace retiring and expiring capacity. In April of 2025, TVA released a request for proposals for up to 2,250 MW of new build energy resources for potential PPAs. Energy resources that may participate in this RFP are utility-scale natural gas, battery energy storage systems ("BESS"), solar plus BESS, and solar generation that demonstrate the ability to be commercially operable by CY 2031. TVA is currently evaluating these proposals.

TVA worked with stakeholders and the public on the 2025 Integrated Resource Plan ("IRP"), a comprehensive plan that will help shape TVA's energy system through 2050. The final IRP was expected to be published in 2025; however, publication of the final IRP has been delayed.

*Natural Gas-Fired Units.* TVA continues to evaluate adding flexible lower carbon-emitting gas plants as a strategy

to maintain reliability. Pre-commercial plant operations began on Johnsonville Aeroderivative CT Units 25-28 in the first quarter of 2025 and began on Units 21-24 and 29-30 in the second quarter of 2025. Units 21-25 and 27-30 became operational on May 6, 2025.

TVA is replacing generation for one unit at Cumberland Fossil Plant with a 1,450 MW combined cycle plant that is expected to be operational by the end of CY 2026. As of June 30, 2025, TVA had spent $1.7 billion on this project. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Natural Gas-Fired Units* in the Annual Report.

To operate the Cumberland Combined Cycle Plant, TVA has contracted for the transportation of gas from a gas pipeline that will need to be constructed. To construct the pipeline, the pipeline company, Tennessee Gas Pipeline Company, L.L.C. ("Tennessee Gas"), obtained permits from various state and federal agencies and a certificate of public convenience and necessity from the Federal Energy Regulatory Commission ("FERC"). Challenges to two permits were brought in the United States Court of Appeals for the Sixth Circuit ("Sixth Circuit"), and on October 11, 2024, the Sixth Circuit issued orders staying the permits until the court could review the merits of these cases. On April 4, 2025, the Sixth Circuit denied the petitions for review in both cases, and on April 15, 2025, the Sixth Circuit lifted the temporary stay. A challenge to the FERC certificate is pending before the United States Court of Appeals for the District of Columbia Circuit ("D.C. Circuit"). The D.C. Circuit heard oral arguments on the merits on March 4, 2025, but has not yet issued a ruling. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Optimum Energy Portfolio* — *Natural Gas-Fired Unit*s in the Annual Report and Note 21 — *Contingencies and Legal Proceedings* — *Legal Proceedings* — *Challenge to Certificate for Cumberland Pipeline* in this Quarterly Report.

TVA is constructing 1,500 MW of natural gas generation at TVA's Kingston site that is expected to be operational by the end of CY 2027. As of June 30, 2025, TVA had spent $1.5 billion on this project. In addition, in March 2025, TVA issued a

request for proposal for battery storage related to the Kingston energy complex. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Natural Gas-Fired Units* in the Annual Report for additional information regarding this project and Note 21 — *Contingencies and Legal Proceedings* — *Legal Proceedings* — *Challenge to Kingston Construction Permit* in this Quarterly Report for information about a challenge to the Kingston construction permit.

In 2024, TVA made available to the public a draft environmental impact statement ("EIS") to assess the impacts associated with the construction and operation of a 500 MW simple cycle CT at New Caledonia on TVA land. The final EIS was published in January 2025, and TVA documented its final decision with the Record of Decision on February 13, 2025. As of June 30, 2025, TVA had spent $214 million on the New Caledonia project and could spend up to an additional $648 million.

TVA is also exploring a 200 MW aeroderivative CT project at TVA's Allen site, and the draft EIS was made available for public comment in March 2025. In addition, TVA is exploring a 350 MW CT project at TVA's Lagoon Creek site. As of June 30, 2025, TVA had spent less than $1 million on the project at Lagoon Creek and could spend up to an additional $670 million. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Optimum Energy Portfolio* — *Natural Gas-Fired Unit*s in the Annual Report.

*Hydroelectric Pumped-Storage.* TVA is exploring alternatives for a potential future pumped-storage facility, and the draft EIS was made available for public comment in May 2025.

*Renewable Power Purchase Agreements*. TVA issued a carbon-free RFP in 2022, and in the second quarter of 2025, TVA signed one power purchase agreement for 150 MW of solar generation. In total, TVA signed seven power purchase agreements totaling 1,141 MW of solar generation and 220 MW of battery storage capacity from the carbon-free RFP which are expected to come online by the end of CY 2028. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations *— Key Initiatives and Challenges — Renewable Power Purchase Agreements* in the Annual Report.

*Self-Directed Solar.* TVA has elected to pursue a competitive selection process with third parties for the development of a photovoltaic solar facility and plans to enter into a long-term PPA to purchase the energy generated by the facility. An RFP was issued to this effect in 2024, and selection of the awardee is anticipated by the end of CY 2025. In addition, a draft EIS was made available for public comment in January 2025. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Optimum Energy Portfolio* — *Self-Directed Solar* in the Annual Report.

*Small Modular Reactors.* In January 2025, TVA and a consortium of co-applicants applied for a U.S. Department of Energy ("DOE") grant to support the potential development and future deployment of a small modular reactor ("SMR") at TVA's Clinch River site. The potential development and any future deployment of an SMR at the Clinch River site are subject to TVA Board approval. TVA is following a structured planning process that advances the Clinch River project in phases at which the TVA Board will evaluate and consider approving any next steps. This funding could support not only the deployment of this first-of-a-kind technology, but also help establish the supply chain for advanced nuclear and support future deployment of the reactor across the United States. In April 2025, TVA and the consortium of co-applicants submitted a revised application to address new DOE guidance regarding the grant.

In the second quarter of 2025, TVA requested public comment on a draft Supplemental Environmental Impact Statement that addresses the potential environmental effects associated with site preparation, construction, operation, and decommissioning of one SMR, the GE Hitachi Nuclear Energy BWRX-300, at the Clinch River site. In the third quarter of 2025, TVA submitted a construction permit application to the Nuclear Regulatory Commission ("NRC") for a BWRX-300 reactor at the Clinch River Nuclear Site. In July 2025, the NRC completed the acceptance review of the application and accepted the application. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Optimum Energy Portfolio* — *Small Modular Reactors* in the Annual Report.

*Automated Energy Exchange Platform.* In July 2023, the D.C. Circuit remanded FERC's approval of the Southeast Energy Exchange Market ("SEEM"), sending the matter back to FERC for additional proceedings. On March 14, 2025, after further review of the record, FERC affirmed its approval of SEEM. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Optimum Energy Portfolio* — *Automated Energy Exchange Platform* in the Annual Report.

*Extreme Flooding Preparedness*

Since 2009, TVA has performed further hydrology modeling of portions of the TVA watershed using updated modeling tools. TVA submitted updated hydrology models to the NRC incorporating an approved methodology for Watts Bar Nuclear Plant Units 1 and 2 in December 2023. The new hydrologic analysis was approved by the NRC in May 2025.

*Sequoyah Nuclear Plant Unit 2*

Sequoyah Unit 2 tripped on July 30, 2024, due to failure of the main generator. As a result, the project to restack and rewind the main generator was pulled forward in the Nuclear Life Extension plan. In June 2025, the unit returned to service and, as of June 30, 2025, TVA had spent $133 million related to this project and expects to spend an additional $8 million. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Sequoyah Nuclear Plant Unit 2* in the Annual Report.

*Hurricane Helene*

In late September 2024, Hurricane Helene caused significant damage in communities in East Tennessee and Western

North Carolina. TVA completed inspections at numerous dams, finding no substantial impacts. In July 2025, TVA completed debris cleanup at Douglas Reservoir to aid major disaster declarations with the Federal Emergency Management Agency ("FEMA"). TVA is receiving reimbursement from FEMA for this work. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Hurricane Helene* in the Annual Report.

*Coal Combustion Residuals*

TVA is pursuing a programmatic approach to address environmental impacts related to the previous storage and disposal of its CCR in accordance with applicable law ("CCR Program"). Under the CCR Program, TVA performed stability remediation of all at-risk facilities, completed the conversion of all operational coal-fired plants to dry CCR storage, and ceased operation of wet CCR storage facilities.

As of June 30, 2025, TVA had spent approximately $3.3 billion on its CCR Program. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Coal Combustion Residuals* in the Annual Report.

*Real Property Portfolio*

TVA engages in ongoing Tennessee Valley-wide real property portfolio evaluations of buildings, structures, and land as

part of the strategic real estate program, which focuses on reducing cost, right-sizing the portfolio, and aligning real estate

holdings with TVA's strategic direction. In February 2025, the TVA Board voted to surplus the Missionary Ridge and Blue Ridge buildings at the Chattanooga Office Complex, subject to Chief Executive Officer ("CEO") determination of disposal. Subject to such further CEO determination, these buildings will remain in operation until the system operations center becomes fully operational, which is expected in CY 2026. See Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* — *Real Property Portfolio* in the Annual Report.

*Corporate Governance*

*Board.* The terms of Beth H. Harwell and Brian E. Noland as members of the TVA Board ended January 3, 2025, with the adjournment of the most recent session of Congress. Although their terms of office expired May 18, 2024, the TVA Act permitted them to continue to serve as Directors until the end of this session of Congress.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;L. Michelle Moore's, Joe H. Ritch's, and Beth P. Geer's appointments as members of the TVA Board ended March 27, 2025, April 1, 2025, and June 10, 2025, respectively, at the direction of the President of the United States. With the departure of Mr. Ritch in April, Director William J. Renick assumed the role of Board Chair pursuant to the TVA Board's decision on February 13, 2025, nominating Mr. Renick as chair-elect of the TVA Board.

The TVA Board now has three members and, thus, is without a quorum. The TVA Board continues to have all authorities as described in Section 1.6 of the TVA Bylaws to "continue to exercise those powers of the Board which are necessary to assure continuity of operations of [TVA] along the lines established while [TVA] was guided by a quorum of the Board, but shall not have the authority to direct [TVA] into new areas of activity, to embark on new programs, or to change [TVA's] existing direction" ("Section 1.6 Authority"). On July 15, 2025, the TVA Board delegated its Section 1.6 Authority to the CEO, provided that the delegation will become effective only in the event the TVA Board ceases to have any members and, once effective, will extend until the TVA Board regains at least one member, and provided further that the CEO will not have any authority to make decisions affecting the compensation of the CEO.

*Management.* On January 13, 2025, TVA announced that Thomas C. Rice had been appointed as TVA's new Senior Vice President and Chief Financial Officer, effective January 27, 2025. In his new position, Mr. Rice is responsible for directing all of TVA's financial functions, including treasury, risk management, accounting, financial operations and performance, financial planning, and investor relations. He succeeded John M. Thomas, III, who, on December 2, 2024, announced his retirement from TVA effective March 7, 2025. Until his retirement, Mr. Thomas served as Executive Vice President and Advisor to the CEO and assisted with the transition of his responsibilities. Mr. Rice's title changed to Executive Vice President and Chief Financial Officer, effective July 28, 2025.

On January 29, 2025, Jeffrey J. Lyash, TVA's President and CEO, notified his executive leadership team, and the TVA Board, of his intention to retire no later than October 2, 2025. On March 31, 2025, TVA announced that Donald A. Moul had been appointed as TVA's new President and CEO, effective April 9, 2025. Mr. Lyash continued to serve until April 30, 2025, to support the transition.

In his new position, Mr. Moul will be entitled to the compensation set forth in his offer letter accepted as of March 25, 2025, and the most significant elements of his compensation are described below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Moul's salary will increase from $844,052 to $1,200,000.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Moul will continue to be a participant in TVA's Executive Annual Incentive Plan ("EAIP"), and his target annual incentive opportunity will increase from 80 percent to 110 percent of his annual salary. For the year ending September 30, 2025, Mr. Moul's EAIP award will be prorated based on time spent in his two roles. The EAIP award is contingent upon continued employment through September 30, 2025, and is subject to achievement of performance goals.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Mr. Moul will continue to be a participant in TVA's Long-Term Incentive Plan ("LTIP").

–Under the long-term performance ("LTP") component of the LTIP, Mr. Moul's target grant opportunity for the performance cycle ending on September 30, 2025, will remain $1,425,000, and his target grant opportunity for the performance cycle ending on September 30, 2026 will be $2,450,000. Except as described below in Item 5, LTP awards will vest upon the completion of the three-year performance cycles, contingent upon continued employment through the vesting dates and subject to achievement of performance goals.

–Under the long-term retention component of the LTIP, Mr. Moul's aggregate grant opportunity for the year ending on September 30, 2025, will be $961,667, and his aggregate grant opportunity for the year ending on September 30, 2026 will be $1,050,000. Except as described below in Item 5, Mr. Moul will receive these amounts if he remains employed by TVA through the end of the retention periods.

Effective April 2, 2025, David B. Fountain's tenure as TVA's Executive Vice President, General Counsel and Corporate Secretary ended. Mr. Fountain's no-fault separation from TVA was finalized on April 7, 2025.

On July 14, 2025, Tim Rausch, TVA's Executive Vice President and Chief Nuclear Officer, informed TVA's CEO of his intention to separate from service no later than March 1, 2026, and executed a separation and release agreement.

*Executive Actions*

On January 20, 2025, President Trump issued an executive order ("EO") that revoked a number of EOs, including several EOs relating to environmental matters. See *Environmental Matters* — *General* below. See also *Environmental Matters* — *Clean Air Act Programs and Regulations* — *Mercury and Air Toxics Standards for Electric Utility Units* for a discussion of a proclamation issued on April 8, 2025. On January 20, 2025, President Trump also issued EO 14154, "Unleashing American Energy," which in part instructed agencies to pause the disbursement of funds appropriated under the IRA and BIL. On January 21, 2025, the Office of Management and Budget issued Memorandum M-25-11, which clarified that EO 14154 requires agencies to pause disbursement of funds appropriated under the IRA or the BIL only for programs that are inconsistent with the policy of section 2 of EO 14154, related to the Green New Deal, including consumer mandates on electric vehicles and appliances. While the IRA and BIL funding freeze under EO 14154 likely does not apply to funding that TVA is seeking, other governmental actions and funding restrictions may delay any award of grants for which TVA has applied under these acts. Furthermore, President Trump and the Administration have taken a number of other actions that may impact TVA, and multiple court decisions may affect the implementation of these actions. TVA is currently reviewing these actions and related court decisions to evaluate the impact to TVA and is updating its policies and programs as appropriate.

On July 4, 2025, the President signed into law the budget reconciliation bill referred to as the One Big Beautiful Bill Act ("Act"). Among other things, the Act introduces significant changes to a range of federal tax credit programs under the IRA, many of which are directly relevant to TVA's ongoing and planned energy initiatives. These changes include terminations, modifications, and new restrictions on various clean energy and efficiency credits and could directly affect the financial viability of clean-energy alternatives and the cost or availability of power acquired through solar PPAs. TVA continues to evaluate its energy portfolio to actively develop long-term plans to take into consideration these changes, which may impact future decisions related to the mix of energy sources TVA utilizes. TVA is currently evaluating the impact of these legislative changes.

**Environmental Matters**

There have been no material changes to the environmental matters described in Part I, Item 1, Business — *Environmental Matters* of the Annual Report, except as described below.

*General*

On January 20, 2025, President Trump issued an EO that revoked a number of EOs, including the following EOs discussed in Part I, Item 1, Business — *Environmental Matters — Climate Change — Executive Actions* in the Annual Report: (1) EO 13990, "Protecting Public Health and the Environment and Restoring Science To Tackle the Climate Crisis"; (2) EO 14008, "Tackling the Climate Crisis at Home and Abroad"; (3) EO 14030, "Climate-Related Financial Risk"; (4) EO 14057, "Catalyzing Clean Energy Industries and Jobs Through Federal Sustainability"; (5) EO 14082, "Implementation of the Energy and Infrastructure Provisions of the Inflation Reduction Act of 2022"; and (6) EO 14096, "Revitalizing Our Nation's Commitment to Environmental Justice for All."

On March 12, 2025, the Environmental Protection Agency ("EPA") Administrator announced that EPA will reconsider 31 rules, including (1) regulations on power plants, (2) Mercury and Air Toxics Standards, (3) steam electric effluent limitation guidelines, (4) National Ambient Air Quality Standards for particulate matter, (5) regulations regarding regional haze, (6) the Good Neighbor Plan, and (7) CCR regulations. TVA cannot predict the outcome of such reevaluations or their impact on TVA's financial results or operations. See Part I, Item 1, Business — *Environmental Matters* in the Annual Report.

*Clean Air Act Programs and Regulations*

*Regional Haze Program.* In February 2025, the TVA Board approved funding of $233 million to construct scrubbers at two additional units at Shawnee Fossil Plant by the end of 2028. Inclusive of the costs for these two scrubbers, at June 30, 2025, TVA's estimated potential expenditures on Clean Air Act control projects are $48 million, $98 million, and $216 million for the remainder of 2025, 2026, and 2027 - 2029, respectively.

*Mercury and Air Toxics Standards for Electric Utility Units.* On April 8, 2025, the President issued a proclamation exempting certain coal-fired power plants for two years from compliance with the updated Mercury and Air Toxics Standards that EPA published in May 2024. The President has exempted TVA's Cumberland, Gallatin, Kingston, and Shawnee fossil plants for the period beginning July 8, 2027 and concluding July 8, 2029. These plants must continue to comply with the Mercury and Air Toxics Standards that were in effect prior to the May 2024 update. These exemptions are currently subject to legal challenge.

*Climate Change*

*Emissions.* Emissions of nitrogen oxides ("NOx") and sulfur dioxide ("SO2") began being regulated in 1995 and 1977, respectively. Emissions of NOx and SO2 have been reduced by 97 percent and 99 percent, respectively, since their initial year of regulation.

|:---|:---|:---|
| **Emissions and Intensity Rates** <sup>(1)</sup> | **CY 2024** | **CY 2023** |
| **Nitrogen Oxides (NOx)**<sup>(2)</sup> | | |
| &nbsp;&nbsp;&nbsp;&nbsp;Total NOx Emissions (MT) | 14743 | 13221 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total NOx Emissions Intensity (MT/Net MWh) | 0.000107 | 0.000098 |
| **Sulfur Dioxide (SO2)**<sup>(2)</sup> |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Total SO2 Emissions (MT) | 19992 | 17736 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total SO2 Emissions Intensity (MT/Net MWh) | 0.000145 | 0.000131 |
| **Mercury (Hg)** |  |  |
| &nbsp;&nbsp;&nbsp;&nbsp;Total Hg Emissions (kg) | 49.1 | 47.4 |
| &nbsp;&nbsp;&nbsp;&nbsp;Total Hg Emissions Intensity (kg/Net MWh) | 0.0000004 | 0.0000004 |

---

<u>Notes</u>

(1) Intensity rates are calculated based on generation from TVA's most recent fiscal year for years indicated and emissions data from the most recent CYs.

(2) Emissions data is consistent with Edison Electric Institute Environmental, Social, Governance, and Sustainability Report standards, which are based on metric tons ("MTs"), whereas overall CO2 emission rates and baseline reductions from historical levels are based on short tons.

For CY 2024, TVA's emissions of carbon dioxide ("CO2") from its owned and operated units, including purchased power and Renewable Energy Certificate retirement adjustments which reduce the reportable CO2 emissions, were 54 million tons, resulting in a TVA system average, as delivered, CO2 emission rate of 680 lbs/MWh. This represents a 53 percent and 49 percent reduction in mass carbon emissions and TVA's carbon emission rate, respectively, from 2005 levels.

*Cleanup of Solid and Hazardous Wastes*

*Coal Combustion Residuals.* In August 2015, TDEC issued an order that includes an iterative process through which TVA and TDEC will investigate, assess, and remediate any unacceptable risks resulting from coal combustion residuals ("CCR") management and disposal at TVA CCR units in the State of Tennessee. As part of this process, TVA has submitted environmental assessment reports ("EARs") to TDEC, and after the EARs are approved, TVA will submit Corrective Action/Risk Assessment ("CARA") Plans that will identify the unacceptable risks and TVA's proposed remediation. TDEC will review the CARA Plans and provide comments, and TVA will make revisions to address TDEC's comments until TDEC approves a final CARA Plan for each site. The public also will have an opportunity to review and comment on each CARA Plan prior to TDEC's approval of the final plan. TDEC approved the EAR for Bull Run Fossil Plant ("Bull Run") on November 15, 2024, and TVA submitted the initial draft of the Bull Run CARA Plan to TDEC in January 2025. TDEC approved the EAR for Johnsonville Fossil Plant ("Johnsonville") on March 31, 2025, and TVA submitted the initial draft of the Johnsonville CARA Plan to TDEC in May 2025. In July 2025, TDEC approved the final CARA plan for John Sevier Fossil Plant. See Part I, Item I, Business — *Environmental Matters* — *Cleanup of Solid and Hazardous Wastes* — *Coal Combustion Residuals* in the Annual Report.

On July 22, 2025, EPA issued a direct final rule that extends deadlines for CCR management unit ("CCRMU") requirements. The rule allows the two parts of the CCRMU facility evaluation reports to be prepared concurrently so long as both reports are submitted no later than February 8, 2027. In addition, the rule extends the deadline for owners or operators of CCRMU to comply with the groundwater monitoring provisions by 15 months, to no later than August 8, 2029. Since the facility evaluation reports and groundwater monitoring requirements are prerequisites for other CCRMU requirements, the rule also makes conforming changes to the remaining CCRMU compliance deadlines. TVA is still evaluating the rule and its potential impact on TVA's operations. See Part I, Item I, Business — *Environmental Matters* — *Cleanup of Solid and Hazardous Wastes* — *Coal Combustion Residuals* in the Annual Report.

**Legal Proceedings**

From time to time, TVA is party to or otherwise involved in lawsuits, claims, proceedings, investigations, and other legal matters ("Legal Proceedings") that have arisen in the ordinary course of conducting its activities. As of June 30, 2025, TVA had accrued $10 million with respect to Legal Proceedings. No assurance can be given that TVA will not be subject to significant additional claims and liabilities. If actual liabilities significantly exceed the estimates made, TVA's results of operations, liquidity, and financial condition could be materially adversely affected.

For a discussion of certain current material Legal Proceedings, see Note 21 *— Contingencies and Legal Proceedings — Legal Proceedings*, which discussions are incorporated into this Part I, Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations*.*

**Critical Accounting Estimates**

The preparation of financial statements requires TVA to estimate the effects of various matters that are inherently uncertain as of the date of the financial statements. Although the financial statements are prepared in conformity with accounting principles generally accepted in the U.S., TVA is required to make estimates and assumptions that affect the reported amounts of assets and liabilities, the disclosure of contingent assets and liabilities, and the amounts of revenues and expenses reported during the reporting period. Each of these estimates varies in regard to the level of judgment involved and its potential impact on TVA's financial results. Estimates are deemed critical either when a different estimate could have reasonably been used, or where changes in the estimate are reasonably likely to occur from period to period, and such use or change would materially impact TVA's financial condition, results of operations, or cash flows. TVA's critical accounting estimates and policies are discussed in Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Critical Accounting Estimates* and Note 1 — *Summary of Significant Accounting Policies* of the Notes to Consolidated Financial Statements in the Annual Report.

**New Accounting Standards and Interpretations**

For a discussion of new accounting standards and interpretations, see Note 2 — *Impact of New Accounting Standards and Interpretations*, which discussion is incorporated into this Part I, Item 2, Management's Discussion and Analysis of Financial Condition and Results of Operations.

**Legislative and Regulatory Matters**

For additional discussion on legislative and regulatory matters, including a discussion of environmental legislation and regulation, see *Environmental Matters* and *Key Initiatives and Challenges* above. Also, see Part I, Item 1, Business — *Environmental Matters* and Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Key Initiatives and Challenges* of the Annual Report.

TVA does not engage, and does not control any entity that is engaged, in any activity listed under Section 13(r) of the Securities Exchange Act of 1934 (the "Exchange Act"), which requires certain issuers to disclose certain activities relating to Iran involving the issuer and its affiliates. Based on information supplied by each such person, none of TVA's directors and executive

officers are involved in any such activities. While TVA is an agency and instrumentality of the U.S., TVA does not believe its disclosure obligations, if any, under Section 13(r) extend to the activities of any other departments, divisions, or agencies of the U.S.

**ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

There are no material changes related to market risks disclosed under Part II, Item 7, Management's Discussion and Analysis of Financial Condition and Results of Operations — *Risk Management Activities* in the Annual Report. See Note 14 — *Risk Management Activities and Derivative Transactions* for additional information regarding TVA's derivative transactions and risk management activities.

**ITEM 4. CONTROLS AND PROCEDURES**

**Disclosure Controls and Procedures**

TVA maintains disclosure controls and procedures designed to ensure that information required to be disclosed by TVA in reports that it files or submits under the Exchange Act is recorded, processed, summarized, and reported, within the time periods specified in the Securities and Exchange Commission's rules and forms, and is accumulated and communicated to TVA's management, as appropriate, to allow timely decisions regarding required disclosure. TVA's management, including the President and CEO, the Senior Vice President and Chief Financial Officer, and members of the Disclosure Control Committee, including the Vice President and Controller (Principal Accounting Officer) (collectively "management"), evaluated the effectiveness of TVA's disclosure controls and procedures (as defined in Rule 13a-15(e) under the Exchange Act) as of June 30, 2025. Based on this evaluation, management concluded that TVA's disclosure controls and procedures were effective as of June 30, 2025.

**Changes in Internal Control over Financial Reporting**

During the quarter ended June 30, 2025, there were no changes in TVA's internal control over financial reporting that materially affected, or are reasonably likely to materially affect, TVA's internal control over financial reporting.

**PART II - OTHER INFORMATION**

**ITEM 1. LEGAL PROCEEDINGS**

From time to time, the Tennessee Valley Authority ("TVA") is party to or otherwise involved in lawsuits, claims, proceedings, investigations, and other legal matters ("Legal Proceedings") that have arisen in the ordinary course of conducting its activities. While the outcome of the Legal Proceedings to which TVA is a party cannot be predicted with certainty, any adverse outcome to a Legal Proceeding involving TVA may have a material adverse effect on TVA's financial condition, results of operations, and cash flows.

For a discussion of certain current material Legal Proceedings, see Note 21 — *Contingencies and Legal Proceedings* — *Legal Proceedings*, which discussions are incorporated by reference into this Part II, Item 1, Legal Proceedings.

**ITEM 1A. RISK FACTORS**

There are no material changes related to risk factors from the risk factors disclosed in Part I, Item 1A, Risk Factors in the Annual Report, except as described below.

**The recent loss of a quorum of the TVA Board of Directors could limit TVA's ability to adapt to changing business conditions.**

Under the TVA Act, a quorum of the TVA Board of Directors ("TVA Board") is five members. On April 1, 2025, the TVA Board lost a quorum, and it currently has three members. Without a quorum, the TVA Board may not have authority to direct TVA into new areas of activity, to embark on new programs, or to change TVA's existing direction. As such, the loss of a quorum for an extended period of time may have a negative impact on TVA's ability to change the rates TVA charges for power, change long-term objectives, plans, and policies, and respond to significant changes in technology, the regulatory environment, or the industry overall and, in turn, negatively affect TVA's cash flows, results of operations, financial condition, and reputation. TVA believes that the actions taken by the TVA Board since April 1, 2025, are authorized under its bylaws or otherwise. Becoming a member of the TVA Board requires confirmation by the U.S. Senate following appointment by the President. This process has been and could again in the future be subject to extended delays. TVA cannot predict when the TVA Board will again have a quorum or whether any challenges will arise associated with its operations in the interim and any consequences as a result. See Part I, Item 1A, Risk Factors — *Human Capital and Management Risks* — *Loss of a quorum of the TVA Board could limit TVA's ability to adapt to changing business conditions* in the Annual Report.

**ITEM 5. OTHER INFORMATION**

**Insider Trading Arrangements and Policies**

During the three months ended June 30, 2025, no director or officer of TVA notified TVA of the adoption or termination of a "Rule 10b5-1 trading arrangement" or "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408(a) of Regulation S-K.

**Compensation Actions**

On July 23, 2025, the TVA Board took several actions related to compensation. The TVA Board (1) established 2026 performance measures and goals for the Enterprise Scorecard for the Winning Performance Team Incentive Plan ("WPTIP") and Executive Annual Incentive Plan ("EAIP") and (2) established performance measures and goals for the 2026 – 2028 performance cycle under the Long-Term Incentive Plan ("LTIP"). Each of these items is discussed in more detail below.

**2026 Enterprise Scorecard for WPTIP and EAIP**

The Board established the following performance measures and goals for the Enterprise Scorecard for both the WPTIP and the EAIP for 2026:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Performance Measure** | **Weight** | **Threshold** | **Target** | **Stretch** |
| **SBU Controllable O&M and Base Capital Spend** <sup>(1)</sup> | 40% | 2% SBU O&M /<br>4% Capital Over Budget | 2026 Budget | 2% SBU O&M /<br>4% Capital Under Budget |
| **Serious Injury Incident Rate** <sup>(2)</sup> | 15% | 0.03 | 0.01 | 0.00 |
| **Transmission Performance Indicator** <sup>(3)</sup> | 15% | 50 | 100 | 200 |
| **Generation Performance Indicator** <sup>(4)</sup> | 15% | 50 | 100 | 200 |
| **Nuclear Performance Indicator** <sup>(5)</sup> | 15% | Equidistant from Target | 2% | Comparable Fleet Top Quartile 24-month average as of September 2025 |

---

<u>Notes</u>

(1) Strategic Business Unit ("SBU") Controllable Operating & Maintenance ("O&M") and Base Capital Spend equals the total Non-Fuel O&M and Base Capital expenses for corporate and operational SBU organizations (excludes Board of Directors).

(2) The Serious Injury Incident Rate is a mathematical calculation used by Edison Electric Institute that quantifies the extent of injury for serious injuries and fatalities from events within the control of the employee and/or the employer.

(3) Transmission Performance Indicator is an aggregate measure of the overall reliability of TVA's transmission system.

(4) The Generation Performance Indicator is an aggregate measure of the overall reliability of TVA's power operations generation fleet based on key performance measures in Gas, Hydro, and Coal that are intended to ensure that TVA's fleet of power operations generation assets are available and reliable to meet system demand.

(5) The Nuclear Performance Indicator is the Annualized Online Reliability Loss Factor, which is the 12-month ratio of all generation losses minus refueling outage ("RFO") and exempt losses to reference energy generation minus RFO and exempt losses in a normal fuel cycle period, per standard industry guidelines. This measure monitors performance between refueling outages to obtain high unit and energy production reliability.

|:---|:---|:---|:---|:---|
| **Transmission Performance Indicator** | **Weight** | **Threshold** | **Target** | **Stretch** |
| **Load Not Served** <sup>(1)</sup> | 60% | 4.4 | 3.7 | 3.0 |
| **Outages per Hundred Miles per Year** <sup>(2)</sup> | 20% | 2.87 | 2.61 | 2.35 |
| **Connection Point Interruption Frequency** <sup>(3)</sup> | 20% | 0.64 | 0.53 | 0.42 |

---

<u>Notes</u>

(1) Load Not Served ("LNS") is a measure of the magnitude and duration of transmission system outages that affect TVA customers expressed in system minutes. TVA manages this critical indicator to reduce the impact of customer outages. An automatic customer interruption with a duration of one minute or greater is tracked as an LNS event. LNS events caused by TVA on a distributor system will also count as a TVA event even if the TVA system remains energized. LNS excludes interruptions due to declared major events, variances, verified tornadoes, gunfire, vandalism, ice formation, and foreign object/vehicle (DUI, DWI, hit and run, or suicide).

(2) Outages per Hundred Miles per Year ("OHMY") is the number of automatic interruptions (sustained and momentary) to lines greater than or equal to 100-kV per 100 miles of transmission line per year. OHMY excludes interruptions due to declared major events, variances, verified tornadoes, gunfire, vandalism, ice formation, foreign object/vehicle (DUI, DWI, hit and run, or suicide), and nested interruptions.

(3) Connection Point Interruption Frequency ("CPIF") measures reliability from the customer's perspective. CPIF tracks interruptions of power, including momentary interruptions, at connection points caused by the transmission system. CPIF includes automatic and emergency forced outages and excludes prearranged (scheduled or planned) and operational outages as well as interruptions due to declared major events, variances, verified tornadoes, gunfire, vandalism, ice formation, and foreign object/vehicle (DUI, DWI, hit and run, or suicide).

<u>Notes</u>

(1) Combined Cycle Equivalent Forced Outage Rate ("EFOR") measures the generation lost due to forced events as a percentage of time the unit would have been scheduled to run for TVA-operated combined cycle generating assets, based on Generating Availability Data System ("GADS") event reporting guidelines for megawatt hour losses. Combined Cycle EFOR excludes GADS events classified as outside management control and variances.

(2) Hydro EFOR reflects the percentage of time over a given period that a generating unit is in forced outage. This measure includes startup failures and is based on GADS event reporting guidelines for megawatt hour losses. Hydro EFOR excludes GADS events classified as outside management control and variances.

(3) Coal EFOR reflects the percentage of time over a given period that a generating unit is in forced outage. This measure includes startup failures and is based on GADS event reporting guidelines for megawatt hour losses. Coal EFOR excludes GADS events classified as outside management control and variances.

(4) Combustion Turbine ("CT") Economic Starting Reliability reflects the percentage of successful attempts to start up a unit for generation, performance testing, or black start over a given period that a generating unit was available for TVA-operated CT assets. Total unit performance tests demonstrate that a unit will start and perform as intended. Black start tests demonstrate that a unit will start without relying on external power and perform as intended. CT Economic Starting Reliability excludes GADS events classified as outside management control and variances.

**LTIP Performance Measures and Goals for the 2026 - 2028 Performance Cycle**

The Board approved LTIP performance measures and goals for the 2026 - 2028 performance cycle. These performance measures, along with their associated weights and goals, are as follows:

---

| | | | | |
|:---|:---|:---|:---|:---|
| **Long-Term Incentive Measures** | **Weight** | **Threshold** | **Target** | **Stretch** |
| **Total Spend** <sup>(1)</sup> | 60% | 2% Non-Fuel O&M, Inventory, and Cloud Spend / 4% Capital Spend Over Budget | 2026 - 2028 Cumulative Total Spend Based on the 2026 Budget | 2% Non-Fuel O&M, Inventory, and Cloud Spend / 4% Capital Spend Under Budget |
| **Carbon-Free Performance Indicator** <sup>(2)</sup> | 20% | 50 | 100 | 200 |
| **Powerful Partnerships Survey** <sup>(3)</sup> | 20% | 75 | 79 | 83 |

---

<u>Notes</u>

(1) Total Spend represents total Non-Fuel O&M, Capital, Non-Fuel Inventory, and Cloud Implementation expenses for corporate and operational SBU organizations (excluding the Board of Directors). This measure will support the overall TVA goal of maintaining costs and managing rates based on spending levels approved by TVA management and the Board.

(2) Carbon-Free Performance Indicator measures renewable MW added to the TVA system, energy program savings GWh and capacity MW provided by energy programs, and the ability to meet TVA's operational needs through demand response event performance. This measure supports the evolution of TVA's reliable and clean energy supply into the energy system of the future as well as helps manage the impact of TVA's identified enterprise risk related to planning and execution of the power system.

(3) The Powerful Partnerships Survey is conducted among customers, elected officials, business/economic development leaders, and the general public in the TVA service area to assess the strength of various stakeholder relationships with TVA. This measure supports the effective management of TVA's reputation and ability to achieve desired outcomes and deliver on strategic priorities with stakeholders.

David Fountain

505 Market St, Unit #702

Knoxville, TN 37901

Dear Mr. Fountain,

This Separation and Release Letter Agreement (this "<u>Agreement</u>") is to confirm the understanding that was reached on April 2, 2025, regarding your employment with TVA. The Administrator of TVA's Executive Severance Plan, Amended and Restated as of May 9, 2024, has determined that you are eligible for benefits in accordance with the terms of that plan based on the circumstances of your separation from service and your execution of this Agreement. Your separation from service decision is irrevocable as of the Effective Date of this Agreement, and you will actually separate from TVA service no later than June 1, 2025 (the "<u>Termination Date</u>"). TVA appreciates your valuable service during your tenure with TVA.

<u>No Other Amounts / Benefits Owed</u>. You will be entitled to your current salary, as well as any accrued annual leave, through the effective date of your separation from service (collectively, the "<u>Accrued Benefits</u>"). You agree that, prior to the execution of this Agreement and except for the Accrued Benefits, you were not entitled to receive any further payments or benefits from TVA, and the only payments and benefits that you are entitled to receive from TVA in the future are those specified in this Agreement; provided that your separation will not affect your rights to pension benefits in accordance with the rules of the Tennessee Valley Authority Retirement System or to the balance of your 401(k) account accrued during, and as a result of, your period of service as a TVA employee.

<u>Severance</u>. Subject to your execution and continued compliance with this Agreement, TVA will pay or provide to you, as applicable, the payments and benefits set forth in that certain Executive Severance Plan of TVA, Amended and Restated as of May 9, 2024, a copy of which is attached hereto, at the times and in the manner set forth therein, less applicable taxes and withholdings (the "<u>Severance</u>"). To the extent that there is any conflict between the terms of this Agreement and the Executive Severance Plan of TVA (or any other compensation plans offered by TVA for which you are or were a participant), the terms of the plan(s) control.

<u>Confidentiality and Non-Disparagement</u>. Because of the nature of your position, you have had access to business sensitive information. You agree, except as required by law, not to disclose or use TVA business sensitive information in the future. You also agree that you will make no comments or statements adverse or critical of TVA, its directors, its management, its employees, or any of its programs. Similarly, TVA agrees not to make any comments or statements adverse or critical of you.

<u>Post-Employment Restrictions</u>. You agree that you have received and read a copy of the Summary of Post-Employment Restrictions document which outlines the post-employment guidelines all former TVA employees must follow.

<u>Voluntary Entry</u>. You agree that you understand the provisions of this Agreement and that you voluntarily enter into it and accept it as full and final resolution of all matters related to your TVA employment.

------

<u>Exhibit 10.4</u>

<u>Release</u>. In consideration for receiving the Severance, and for other good and valuable consideration, the sufficiency of which you hereby acknowledge, you hereby expressly release and waive to the maximum extent permitted by applicable law any and all claims or causes of action, whether known or unknown, against TVA and/or its successors, past or present subsidiaries, affiliated companies, branches, or related entities (collectively, including TVA, the "<u>Entities</u>") and/or the Entities' respective past, present, or future directors, officers, agents, employees, insurers, attorneys, assigns, and employee benefit plans (collectively with the Entities, the "<u>Released Parties</u>"), with respect to any matter, including, without limitation, any matter related to your employment with TVA or the termination of that employment relationship (including any claims under Title VII of the Civil Rights Act, the Equal Pay Act, and the Family and Medical Leave Act, but not including any claims under the Federal Employees Compensation Act).

This waiver and release includes, without limitation, claims to wages, including overtime or minimum wages, bonuses, incentive compensation, vacation pay, or any other compensation or benefits; any claims for failure to provide accurate itemized wage statements, failure to timely pay final pay, or failure to provide meal or rest breaks; claims for any loss, cost, damage, or expense arising out of any dispute over the non-withholding or other tax treatment or employment classification; claims for attorneys' fees or costs; claims for penalties; claims of wrongful discharge, constructive discharge, emotional distress, defamation, invasion of privacy, fraud, breach of contract, and breach of the covenant of good faith and fair dealing; any claims of discrimination, harassment, or retaliation based on sex, age, race, national origin, disability, or any other protected basis; any claims under any applicable law prohibiting discrimination, harassment, and/or retaliation; and claims under all other laws, ordinances, and regulations. You covenant not to sue the Released Parties for any of the claims released above, agree not to participate in any class, collective, representative, or group action that may include any of the claims released above, and will affirmatively opt out of any such class, collective, representative, or group action.

<u>Limited Indemnification</u>. TVA agrees to continue to defend and indemnify you against claims that result from your performance of your TVA duties prior to the Termination Date under the terms set out in TVA-SPP-25.1 Legal Representation.

<u>Agreement Confidential</u>. You further agree to treat this matter as confidential and not to discuss the terms of your separation from TVA service except with your family and financial advisor, or as required by law.

<u>Exceptions</u>. This waiver and release covers only those claims that arose prior to your execution of this Agreement and does not apply to (a) the Accrued Benefits, (b) your rights under this Agreement, including to the Severance, or (c) any claim which, as a matter of law, cannot be released by private agreement. Nothing in this Agreement is intended to prevent, restrict, or otherwise discourage you from providing TVA or the Nuclear Regulatory Commission ("<u>NRC</u>") with any information about actual or potential nuclear safety concerns or violations, or from responding to requests for information from the NRC. Section 211 of the Energy Reorganization Act ("<u>ERA</u>") and NRC regulations (10 CFR 50.7) also protect employees from any adverse employment action as a result of their engaging in such protected activities. By your signature below, you confirm that you have already informed TVA management of any nuclear safety concerns you may have in connection with the construction, maintenance, operation, and security of any TVA facilities, including nuclear plants. You also confirm that no adverse employment action is being taken, in any part, as a result of your engaging in protected activities as defined in Section 211 of the ERA or NRC regulations.

Nothing in this Agreement is intended to prevent, restrict, or otherwise discourage you from providing the Office of the Inspector General ("<u>OIG</u>") with any information or from responding to requests for information from the OIG or otherwise precludes you from participating in any investigation or proceeding before any government agency or body or from reporting possible violations of federal or state law or regulation to any governmental agency or entity, legislative body, or self-regulatory organization, or making other disclosures that are protected under the whistleblower provisions of federal or state law or regulation, nor are you required to notify TVA regarding any such reporting, disclosure, or cooperation with the

<u>Exhibit 10.4</u>

government. However, while you may file a charge and participate in any such proceeding, by signing this Agreement, you waive any right, to the extent permitted under applicable law, to bring a lawsuit against the Released Parties and to any individual monetary recovery in any such proceeding or lawsuit.

You acknowledge that the U.S. Defend Trade Secrets Act of 2016 ("<u>DTSA</u>") provides that an individual shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that is made (a) (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and (ii) solely for the purpose of reporting or investigating a suspected violation of law, or (b) in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. In addition, the DTSA provides that an individual who files a lawsuit for

retaliation by an employer for reporting a suspected violation of law may disclose the trade secret to the attorney of the individual and use the trade secret information in the court proceeding, if the individual (i)

files any document containing the trade secret under seal and (ii) does not disclose the trade secret, except pursuant to court order.

<u>Section 409A</u>. The Severance is intended to be exempt from, or comply with, Section 409A of the Internal Revenue Code of 1986, as amended ("<u>Section 409A</u>"). To the extent necessary to prevent the imposition of taxes and penalties under Section 409A, if the Severance could, due to the timing of the Termination Date, be paid in either of two calendar years, such Severance shall be paid in the later such calendar year.

<u>Governing Law</u>. If any provision of the waiver and release contained in this Agreement is found to be unenforceable, it shall not affect the enforceability of the remaining provisions and a court shall enforce all remaining provisions to the fullest extent permitted by law. TVA is a corporate agency and instrumentality of the United States, and this Agreement shall be governed by and construed under federal law. In the event federal law does not provide a rule of decision for any matter or issue under this Agreement, the law of the State of Tennessee shall apply, without taking into account conflict of law principles. You agree that the jurisdiction for any action with respect to this Agreement shall lie in the United States District Court for the Eastern District of Tennessee.

<u>ADEA Waiver</u>. You acknowledge that you are knowingly and voluntarily waiving and releasing any rights you may have under the Federal Age Discrimination in Employment Act ("<u>ADEA Waiver</u>") and that the consideration given for the ADEA Waiver is in addition to anything of value to which you are already entitled. You further acknowledge that: (a) your ADEA Waiver does not apply to any claims that may arise after you sign this Agreement; (b) you are advised to consult an attorney before signing this Agreement; (c) you have 21 calendar days from the date of receipt of this letter (such final date, the "<u>Deadline</u>") to consider this Agreement before you sign it, but you may sign it at any time during the 21 days); (d) if you sign this Agreement, you may cancel it within seven days thereafter; and (e) this Agreement will not be effective until the eighth day after you sign it, provided that you have not cancelled it (the "<u>Effective Date</u>"). Any such cancellation must be in writing and signed by you and must be delivered to me by close of business on the seventh calendar day after you sign this Agreement. If you do not cancel this Agreement, this Agreement will become effective on the eighth calendar day after the date of your signature below. If you cancel this Agreement, it will become null, and void and TVA will not implement any of its terms. You agree that any modifications, material or otherwise, made to this Agreement do not restart or affect in any manner the original 21-day consideration period provided in this section. The offer described in this Agreement will be automatically withdrawn if you do not sign this Agreement within the 21-day consideration period.

<u>Exhibit 10.4</u>

If the provisions which I have set forth above accurately describe the terms of our agreement, please sign this letter at the place indicated below no later than the Deadline and return it to me. This Agreement shall become effective on the Effective Date.
