IRVING, Texas, Aug. 7, 2025 — Vistra Corp. (NYSE: VST) today reported its second quarter 2025 financial results and other highlights.

“With power demand rising, our team at Vistra remains steadfast in our commitment to reliably power American homes and businesses, providing a critical foundation for the U.S. economy,” said Jim Burke, president and CEO of Vistra. “This quarter, we solidified several opportunities to expand our generation capacity and capabilities for decades to come, including through the execution of a definitive agreement to acquire a 2,600-MW natural gas generation fleet spanning the PJM, New England, New York, and California electricity markets, and through NRC approval of a license extension through 2046 for our Perry Nuclear Power Plant in Ohio. Now, each of Vistra’s six nuclear reactors are licensed to operate for a total of 60 years.”

“In addition, the team’s focus on our core business operations through our integrated business model resulted in solid second quarter results, throughout a variety of pricing and weather conditions. The performance year-to-date and the forecast we see for the remainder of 2025 provide increasing confidence in our reiterated 2025 guidance ranges and our increased 2026 midpoint opportunity. We look forward to continuing the momentum and executing on the remainder of the year ahead,” Burke concluded.

Net Income for the second quarter 2025 decreased by $(140) million compared to the second quarter 2024, driven primarily by higher plant outage expense, including Martin Lake Unit 1 and Moss Landing, and an increase in depreciation and amortization due primarily to an increase in capital additions. Ongoing Operations Adjusted EBITDA^1^ for the second quarter 2025 decreased by $(63) million compared to the second quarter 2024, driven primarily by higher plant outage costs.

1 Ongoing Operations excludes the Asset Closure segment. Net Income (Loss) from Ongoing Operations, Ongoing Operations Adjusted EBITDA, and Ongoing Operations Adjusted Free Cash Flow before Growth are non-GAAP financial measures. Any reference to “Ongoing Operations Adjusted FCFbG” is a reference to Ongoing Operations Adjusted Free Cash Flow before Growth. See the “Non-GAAP Reconciliation” tables for further detail. Total segment information may not tie due to rounding.

2 Midpoint opportunities are not intended to be guidance and represent only our estimate of potential opportunities for Ongoing Operations Adjusted EBITDA in 2026 based on market curves as of August 1, 2025. Actual results could vary and are subject to a number of risks, uncertainties and factors, including power price market movements and our hedging strategy. We have not provided a quantitative reconciliation of Ongoing Operations Adjusted EBITDA opportunities for 2026 to GAAP net income (loss) because we cannot, without unreasonable effort, calculate certain reconciling items with confidence due to the variability, complexity, and limited visibility of the adjusting items that would be excluded from Ongoing Operations Adjusted EBITDA in such out year periods.

About Non-GAAP Financial Measures and Items AffectingComparability

“Adjusted EBITDA” (EBITDA as adjusted for unrealized gains or losses from hedging activities, tax receivable agreement impacts, reorganization items, 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 capital expenditures (including capital expenditures for growth investments), 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 it is a useful metric to assess current performance in the period and 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 (Loss) in order to illustrate the company’s Net Income (Loss) 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.
