NOTES TO CONDENSED FINANCIAL STATEMENTS

**1.**BASIS OF PRESENTATION

The accompanying unconsolidated condensed balance sheets, statements of net loss and cash flows present results of operations and cash flows of Vistra Corp. (Parent). Certain information and footnote disclosures normally included in financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to the rules of the SEC. Because the unconsolidated condensed financial statements do not include all of the information and footnotes required by U.S. GAAP, they should be read in conjunction with the financial statements and related notes of Vistra Corp. and Subsidiaries included in the annual report on Form 10-K for the year ended December 31, 2025. Vistra Corp.'s subsidiaries have been accounted for under the equity method. All dollar amounts in the financial statements and tables in the notes are stated in millions of U.S. dollars unless otherwise indicated.

Parent files a consolidated U.S. federal income tax return. Consolidated tax expenses or benefits and deferred tax assets or liabilities have been allocated to the respective subsidiaries in accordance with the accounting rules that apply to separate financial statements of subsidiaries.

**2.**RESTRICTIONS ON SUBSIDIARIES

The Vistra Operations Credit Agreement generally restricts the ability of Vistra Operations to make distributions to any direct or indirect parent unless such distributions are expressly permitted thereunder. As of December 31, 2025, Vistra Operations can distribute approximately $11.2 billion to Parent without the consent of any party. The amount available for distribution has been reduced by distributions made by Vistra Operations to Parent of approximately $1.625 billion, $1.705 billion, and $1.625 billion during the years ended December 31, 2025, 2024 and 2023, respectively. Additionally, Vistra Operations may make distributions to Parent in amounts sufficient for Parent to make any payments required under the TRA or the Tax Matters Agreement or, to the extent arising out of Parent's ownership or operation of Vistra Operations, to pay any taxes or general operating or corporate overhead expenses. As of December 31, 2025, all of the restricted net assets of Vistra Operations may be distributed to Parent.

VISTRA CORP.

**3.**GUARANTEES

Parent has entered into contracts that contain guarantees to unaffiliated parties that could require performance or payment under certain conditions. As of December 31, 2025, there are no material outstanding claims related to guarantee obligations of Parent, and Parent does not anticipate it will be required to make any material payments under these guarantees in the near term.

**4.**DIVIDEND RESTRICTIONS

Under applicable law, Parent is prohibited from paying any dividend to the extent that immediately following payment of such dividend there would be no statutory surplus or Parent would be insolvent.

Parent received $1.625 billion, $1.705 billion, and $1.625 billion in dividends from its consolidated subsidiaries in the years ended December 31, 2025, 2024 and 2023, respectively.
