Earnings Release Highlights

• GAAP first quarter 2026 Net Income of $1,029 million, including an unrealized gain from hedges expected to settle in future years of $723 million, and Ongoing Operations Adjusted EBITDA¹ of $1,494 million.
• Reaffirmed 2026 Ongoing Operations Adjusted EBITDA¹ and Ongoing Operations Adjusted FCFbG¹ guidance ranges of $6.8 billion to $7.6 billion and $3.925 billion to $4.725 billion, respectively.³
• Vistra's corporate issuer credit rating upgraded to Investment Grade at second major credit rating agency.

IRVING, Texas, May 7, 2026 /PRNewswire/ -- Vistra Corp. (NYSE: VST) today reported its first quarter 2026 financial results and other highlights.

"Vistra had an exciting start to 2026, powered by the talent of our people, the capabilities of our generation portfolio, our commitment to our customers, and our ability to grow strategically," said Jim Burke, president and CEO of Vistra. "The first week of the year brought announcements of our plans to acquire the 5,500-MW Cogentrix natural gas generation portfolio, which we continue to target closing in the second half of the year, followed by our signing of long-term power purchase agreements with Meta at our PJM nuclear sites. Vistra performed well, with the fleet delivering strong performance during an extended period of volatile weather including Winter Storm Fern, while the retail business experienced one of the mildest first quarters in Texas history. Finally, Fitch's recent upgrade of our corporate credit rating to Investment Grade, following S&P's action last year, reflects the progress we've made in strengthening our balance sheet and providing visibility into the longer-term earnings power of the company."

"Looking ahead, we remain focused on operational execution and preparing our fleet for the upcoming summer months. Load growth remains strong across our primary markets, and we believe a large, diversified, and dispatchable generation fleet like ours is essential in meeting demand and supporting market reliability. Our integrated model and focus on disciplined execution position us well to deliver reliable power to our customers and create long-term value for our stakeholders."

For the quarter ended March 31, 2026, Vistra reported Net Income of $1,029 million and Ongoing Operations Adjusted EBITDA¹ of $1,494 million. Net Income for the first quarter 2026 increased $1,297 million compared to the first quarter 2025, driven primarily by unrealized mark-to-market gains on derivative positions, with an increase of $1,290 million, as well as higher realized capacity prices and three months contribution from the plants acquired in the Lotus acquisition. Ongoing Operations Adjusted EBITDA for the first quarter 2026 increased by $254 million compared to the first quarter 2025, driven primarily by higher realized energy and capacity prices and three months contribution from the plants acquired in the Lotus acquisition, partly offset by unfavorable results in our retail segment primarily driven by mild weather.

As of May 1, 2026, Vistra had hedged approximately 98% of its expected generation volumes for 2026, approximately 89% for 2027, and approximately 65% for 2028. The company's comprehensive hedging program supports the reaffirmed 2026 guidance ranges and the previously announced Ongoing Operations Adjusted EBITDA midpoint opportunity² range of $7.4 billion to $7.8 billion for 2027.³ The ranges exclude any potential benefits from the pending acquisition of Cogentrix and the recently signed power purchase agreements with Meta, part of which are expected to begin contributing to our Adjusted EBITDA in 2027.

Share Repurchase Program

As of May 1, 2026:

• Vistra executed ~$6.3 billion in share repurchases since November 2021.
• Vistra had ~337 million shares outstanding, representing a ~30% reduction of the amount of the shares outstanding on Nov. 2, 2021.
• ~$1.5 billion dollars of the share repurchase authorization remained available, which we expect to complete by year end 2027.

Liquidity

As of March 31, 2026, Vistra had total available liquidity of approximately $4,173 million, including cash and cash equivalents of $634 million, $2,126 million of availability under its corporate revolving credit facility, and $1,413 million availability under its commodity-linked revolving credit facility. Available capacity under the commodity-linked revolving credit facility reflects the borrowing base of $1,413 million and excludes $337 million of commitments under the facility that were not available to be drawn as of March 31, 2026.

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), "Net Income (Loss) from Ongoing Operations" (net income less net income 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. Vistra uses Net Income (Loss) from Ongoing Operations as a non-GAAP measure that is most comparable to the GAAP measure Net Income in order to illustrate the company's Net Income excluding the effects of the Asset Closure segment, as well as a measure to compare to Ongoing Operations Adjusted EBITDA. 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.
