[***]

Dear Mr. Moul,

This Separation and Release Agreement (this “Agreement”) is to confirm the understanding that was reached between Donald Moul (“you” or “your”) and the Board of Directors of the Tennessee Valley Authority (the “Board”) on April 3, 2026, regarding your employment with TVA. The Board, in its role as Administrator of TVA’s Executive Severance Plan, Amended and Restated as of April 3, 2025, 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 July 1, 2026 (the “Termination Date”). TVA appreciates your valuable service during your tenure with TVA.

No Other Amounts / Benefits Owed. 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 “Accrued Benefits”). You agree that, prior to the execution of this Agreement and except for the Accrued Benefits and the benefits described in the paragraph titled Prorated Plan 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, however, that your separation will not affect your rights to benefits in accordance with provisions of TVA’s Supplemental Executive Retirement Plan (“SERP”), the Rules and Regulations of the Tennessee Valley Authority Retirement System (“TVARS”), or the TVA Savings and Deferral Retirement Plan (“SDRS”), if any. Nothing in this Agreement will affect your rights to benefits under the SERP, TVARS, or SDRS, as determined under the terms and provisions of those plans.

Prorated Plan Benefits. Subject to your execution and continued compliance with this Agreement, TVA will pay or provide to you, as applicable, the payments and benefits to which you are entitled under TVA’s Executive Annual Incentive Plan (“EAIP”) and Long-Term Incentive Plan (“LTIP”), in accordance with the terms of any grants that were awarded to you under each plan prior to the Effective Date. In calculating the payments due under any EAIP and LTIP performance grants referenced in the preceding sentence, you will be entitled to receive the greater of, with respect to any prorated EAIP for the performance period ending on September 30, 2026, the Target EAIP Payout or the EAIP Award (not to exceed a payout at 138.2% performance), and, with respect to any prorated LTIP performance award payment for the performance cycle ending on September 30, 2026, the greater of the target Long-Term Performance Incentive Award or the actual Long-Term Performance Incentive Award (not to exceed a payout at 155.0% performance). With respect to any prorated LTIP performance award payments for the performance cycles ending on September 30, 2027, and September 30, 2028, you will be entitled to the target Long-Term Performance Incentive Award only, in the amounts set forth in the Executive Compensation Illustration for Donald Moul, which is incorporated in this Agreement by reference (the “Severance Illustration”). The total amount of prorated EAIP and LTIP performance awards for the performance cycles ending on September 30, 2026, will not result in the total amount of payments made to you under this agreement exceeding a total of $10,398,388 (the “Severance Cap”) (see row titled “Total of all

Donald Moul

Estimated Payments If Leaving Under Executive Severance Plan” in the Severance Illustration), and the Board will only exercise its discretion with respect to prorated EAIP and LTIP payments for the performance cycles ending on September 30, 2026, in the event that the calculation of your total payments under this Agreement would exceed the Severance Cap because the actual payout percentages would result in exceeding the Severance Cap. Otherwise, the Board will not exercise any negative discretion with respect to your prorated payouts under EAIP and LTIP, nor shall any action by the Board after the date of this Agreement to modify, amend, alter, or cancel either the EAIP or LTIP impact the payments due to you under the terms of this Agreement. To the extent that there is any conflict between the terms of this Agreement and the terms of the EAIP or LTIP, the terms of this Agreement will control.

Severance. 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 April 3, 2025, a copy of which is attached hereto, at the times and in the manner set forth therein, less applicable taxes and withholdings (the “Severance”). For avoidance of doubt, the Cash Separation Payment to be paid to you is in the amount set forth in the Severance Illustration. The section of this Agreement titled Prorated Plan Benefits specifically modifies your rights with respect to In-Progress Annual Incentive Awards, as that term is defined in the Executive Severance Plan. Otherwise, to the extent there is any conflict between the terms of this Agreement and the Executive Severance Plan of TVA, the terms of the plan controls with respect to your Severance.

Policy for the Recovery of Erroneously Awarded Compensation. You acknowledge that TVA adopted a policy, effective November 9, 2023, known as the Policy for the Recovery of Erroneously Awarded Compensation (“Recovery Policy”) and that the Recovery Policy provides for the recovery, in the event of a required accounting restatement, of incentive-based compensation received by current or former executive officers to the extent that the compensation is based on the erroneously reported financial information. You acknowledge that, during your employment with TVA, you have received performance compensation (and that you may receive compensation as outlined in the section of this Agreement titled Prorated Plan Benefits) that may be subject to the Recovery Policy and that TVA may be required to recover from you erroneously paid compensation in the event of a financial restatement as addressed in that policy. You agree that, if TVA is required to recover erroneously awarded compensation in accordance with the Recovery Policy, TVA will take any means necessary, including withholding payments owed to you under the Supplemental Executive Retirement Plan or the Prorated Plan Benefits section of this Agreement and applying TVA’s right of setoff or offset, as applicable, to meet TVA’s recovery obligations under the Recovery Plan and as otherwise consistent with applicable laws and regulations existing at the time of the recovery. You hereby waive any right you have to future payments from TVA, as outlined in this Agreement, to the extent those payments are used to satisfy TVA’s obligations under the Recovery Policy.

Confidentiality and Non-Disparagement. Because of the nature of your position, you have had access to confidential or business sensitive information. You agree, except as required by law, not to disclose or use TVA confidential or business sensitive information in the future. TVA generally, and you specifically, further agree that you and TVA will use reasonable and good faith efforts to ensure that neither party engages in any disparagement of the other, and shall refrain from making any false, negative, or critical statements, implied or expressed, concerning the other. You and TVA further agree to do nothing to damage the other’s business reputation or good will. For purpose of this provision, TVA includes TVA and all current or former TVA Board members, executives, employees and contractors.

Post-Employment Restrictions. 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, and you will comply with all applicable Post-Employment Restrictions as outlined in the Summary and as otherwise required by law.

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.

Limited Indemnification. 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.

Section 211 of the Energy Reorganization Act (“ERA”) 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 (“OIG”) 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 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.
