IRVING, Texas — Nov. 6, 2026 — Vistra Corp. (NYSE: VST) today reported its third quarter 2026 financial results and other highlights.

"I am proud of the results the Vistra team delivered this quarter, " said Jim Burke, president and CEO of Vistra. "Through one of the hottest calendar third quarters on record, our generation team kept the fleet running safely and reliably while our retail team delivered for our customers. At the same time, our people moved forward a significant amount of commercial and development work. I want to thank each one of our team members for their hard work and dedication - it's what truly sets Vistra apart."

"That effort shows in our results, with Ongoing Operations Adjusted EBITDA up more than 50% year over year. This summer brought record weather across our markets, including the new all-time peak demand records in July in both ERCOT and PJM. Through that period, our fleet achieved commercial availability of nearly 95%. Our disciplined approach to spring maintenance paid off when our customers and communities needed reliable power most. With the Cogentrix acquisition now closed, we've added approximately 5,500 MW of new natural gas-fueled generation to our portfolio, and we continue to be well positioned for the growing demand ahead."

Burke concluded, "We also made significant progress on our growth strategy this quarter. We began commercial operations at our Pulaski and Deer Creek facilities, and signed a 20-year agreement with New Era at our Odessa plant. As the power landscape evolves, we continue to see more of these opportunities. Our team remains focused on delivering safe, reliable, and affordable electricity to our customers, and we look forward to finishing the year strong."

Summary of Financial Results for the Three and Nine Months Ended September 30, 2026 and 2025

(Unaudited) (Millions of Dollars)

For the quarter ended September 30, 2026, Vistra reported Net Income of $1,140 million and Ongoing Operations Adjusted EBITDA1 of $2,378 million. Net Income for the third quarter 2026 increased $488 million compared to the third quarter 2025, driven primarily by higher EBITDA and an increase in unrealized mark-to-market gains of $375 million on derivative positions, partly offset by higher depreciation and amortization expense driven primarily by three months' contribution from the plants acquired from Lotus, the partial impairment of the Moss Landing 350 facility, and higher taxes. Ongoing Operations Adjusted EBITDA for the third quarter 2026 increased by $797 million compared to the third quarter 2025, driven primarily by higher realized energy and capacity prices, three months' contribution from the plants acquired from Lotus, and the return of Martin Lake Unit 1 to operational status.

Guidance

As of Oct. 30, 2026, Vistra had hedged approximately 100% of its expected generation volumes for 2026, approximately 98% for 2027, and approximately 78% for 2028.

• Vistra had ~339 million shares outstanding, representing a ~30% reduction of the amount of the shares outstanding on Nov. 2, 2021.

Available capacity under the commodity-linked revolving credit facility reflects the borrowing base of $1,466 million and excludes $284 million of commitments under the facility that were not available to be drawn as of September 30, 2026. Total available liquidity at such date excluded $1,375 million of capacity under Vistra's accounts receivable financing facilities.

About Non-GAAP Financial Measures and Items Affecting Comparability

"Adjusted EBITDA" (EBITDA as adjusted for unrealized gains or losses from hedging activities, transition and merger expenses, non-cash compensation expenses, nuclear decommissioning trust income, asset retirement obligation expenses, and certain other items described from time to time in Vistra’s earnings releases), "Adjusted Free Cash Flow before Growth" (or "Adjusted FCFbG") (cash from operating activities excluding changes in margin deposits and working capital and adjusted for maintenance capital expenditures, other net investment activities, and other items described from time to time in Vistra’s earnings releases), "Ongoing Operations Adjusted EBITDA" (adjusted EBITDA less adjusted EBITDA from Asset Closure segment), and "Ongoing Operations Adjusted Free Cash Flow before Growth" or "Ongoing Operations Adjusted FCFbG" (adjusted free cash flow before growth less cash flow from operating activities from Asset Closure segment before growth) are "non-GAAP financial measures." A non-GAAP financial measure is a numerical measure of financial performance that excludes or includes amounts so as to be different than the most directly comparable measure calculated and presented in accordance with GAAP in Vistra’s consolidated statements of operations, comprehensive income, changes in stockholders’ equity and cash flows. Non-GAAP financial measures should not be considered in isolation or as a substitute for the most directly comparable GAAP measures. Vistra’s non-GAAP financial measures may be different from non-GAAP financial measures used by other companies.

Vistra uses Adjusted EBITDA as a measure of performance and believes that analysis of its business by external users is enhanced by visibility to both Net Income prepared in accordance with GAAP and Adjusted EBITDA. Vistra uses Adjusted Free Cash Flow before Growth as a measure of liquidity and performance, and believes that analysis of capital available to allocate for debt service, growth, and return of capital to stockholders is supported by disclosure of both cash provided by (used in) operating activities prepared in accordance with GAAP as well as Adjusted Free Cash Flow before Growth. Vistra uses Ongoing Operations Adjusted EBITDA as a measure of performance and Ongoing Operations Adjusted Free Cash Flow before Growth as a measure of liquidity and performance, and Vistra’s management and board of directors have found it informative to view the Asset Closure segment as separate and distinct from Vistra’s ongoing operations. The schedules attached to this earnings release reconcile the non-GAAP financial measures to the most directly comparable financial measures calculated and presented in accordance with U.S. GAAP.
