Tennessee Valley Authority

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 $1.0 billion in February 2027. 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 other sources of potential liquidity include three revolving credit facilities totaling $2.5 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 of Directors ("TVA Board") authorized TVA to issue power bonds and enter into other financing arrangements in an aggregate amount not to exceed $3.0 billion during 2026. Other financing arrangements may include, but are not limited to, lease financings, transactions supported by certain power purchase agreements, energy prepayments from customers, and other similar agreements. TVA may also engage from time to time in other alternative forms of financing such as sales of receivables or loans.

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, 2026, were $21.2 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 could provide supplementary funding if needed. Currently, TVA expects to utilize a combination of Bonds, other financings, or potentially additional power revenues through power rate increases to meet its ongoing operational liquidity needs while making planned capital investments. TVA may also receive funding by filing for credits available under the IRA, by applying for grants or other funding available under the Bipartisan Infrastructure Law ("BIL"), from other federal funding opportunities, or from other third-party financing arrangements. See Lease Financings below, Key Initiatives and Challenges — Funding Opportunities, 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, in 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 United States ("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, 2026, the average maturity of long-term power bonds was 13.99 years, and the weighted average interest rate was 4.74 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, 2026. See Lease Financings below, Note 10 — Variable Interest Entities, and Note 13 — Debt and Other Obligationsfor additional information.

The following table provides additional information regarding TVA's short-term borrowings:

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. 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 ratingsin 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 $1.5 billion and $522 million at June 30, 2026 and 2025, respectively. A summary of cash flow components for the nine months ended June 30, 2026 and 2025, follows:

Cash provided by (used in):

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 decreased $193 million for the nine months ended June 30, 2026, as compared to the same period of the prior year. The decrease was primarily due to higher fuel and purchased power payments, the termination of the distributor prepayment program at the end of 2025, and an increase in refunds of transmission interconnection related deposits as compared to the same period of the prior year. The distributor prepayment program allowed customers to prepay their invoices and receive interest credits. These decreases were partially offset by higher customer collections as a result of increased sales volume.

Investing Activities. 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 decreased $629 million for the nine months ended June 30, 2026, as compared to the same period of the prior year. The decrease was driven by less spend related to capacity expansion projects, primarily related to the Cumberland natural gas project nearing completion and higher spend on the Kingston natural gas project in the prior year. In addition, during the nine months ended June 30, 2026, TVA received cash related to insurance proceeds for property recovery and IRA tax credits related to capital assets.

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 decreased $527 million for the nine months ended June 30, 2026, as compared to the same period of the prior year. The decrease is primarily due to a decrease in power bond issuances combined with the use of cash on hand to pay bond maturities. The decrease was partially offset with proceeds from debt of variable interest entities and higher net short-term debt issuance, as compared to the same period of the prior year. 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.

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 and Note 9 —Leases, Note 12 —Variable Interest Entities, Note 15 —Debt and Other Obligations, Note 21 —Benefit Plans, and Note 23 —Commitments and Contingenciesof the Notes to the Consolidated Financial Statements in the Annual Report.

During the nine months ended June 30, 2026, TVA's power purchase obligations increased $1.2 billion primarily due to TVA signing two battery energy storage system agreements which are expected to commence by the summer of 2029. The terms of the agreements are 20 years and capacity payments over the terms of the agreements are expected to total over

$1.3 billion. Both agreements include a lease component. TVA's fuel purchase obligations also increased $574 million primarily due to new and/or extended contracts for nuclear fuel and increased contract costs for natural gas transportation. Nuclear fuel commitments are from 2026 to 2037 and natural gas transportation commitments are from 2026 to 2056. In addition, TVA entered into a new lease financing arrangement during the nine months ended June 30, 2026. See Note 10 —Variable Interest Entities.
