Fiscal Year

References to years (2025, 2024, etc.) in this Annual Report on Form 10-K for the fiscal year ended September 30, 2025 are to TVA's fiscal years ending September 30 except for references to years in the biographical information about directors and executive officers in Part III, Item 10, Directors, Executive Officers, and Corporate Governance, as well as to years that are preceded by "CY," which references are to calendar years.

Notes

References to "Notes" are to the Notes to Consolidated Financial Statements contained in Part II, Item 8, Financial Statements and Supplementary Data in this Annual Report.

Property

TVA generally does not own real property or real property interests (collectively, "real property"). TVA typically acquires real property in the name of the United States ("U.S."), and legal title in such real property is entrusted to TVA as the agent of the U.S. to accomplish the purposes of the TVA Act. TVA acquires personal property in the name of TVA. Accordingly, unless the context indicates the reference is to TVA's personal property, any statement in this Annual Report referring to TVA property shall be read as referring to the real property of the U.S. that has been entrusted to TVA as its agent.

TVA's SEC filings are available to the public at www.tva.com, free of charge, as soon as reasonably practicable after such reports are electronically filed with or furnished to the SEC.
