IRVING, Texas, May 8, 2024 /PRNewswire/ -- Vistra Corp. (NYSE: VST) today reported its first quarter 2024 financial results and other highlights.

"It's been an exciting start to 2024 for Vistra with the team delivering on multiple fronts. I'm proud of our ability to successfully close the acquisition of Energy Harbor within two weeks of receiving FERC approval. Our team hit the ground running on integration and have made significant progress to date. The increase in expected synergies and the identification of sizeable Operational Performance Improvement (OPI) initiatives we are announcing today are a testament to their hard work. We continue to believe that integrating generation and retail businesses is one of Vistra's core competencies and a source of long-term value creation."

Burke continued, "We believe that our integrated model, which combines best-in-class retail and commercial operations with a high-quality portfolio of generation assets enables us to provide our retail customers the electric service they need while delivering consistent financial results for our stakeholders. During another quarter characterized by both winter storms and unseasonably mild weather, Vistra delivered commercial availability of approximately 98% while generating positive profitability and even stronger year-over-year Adj. EBITDA growth, validating the team's approach. We have an incredible team of people who are focused on a safe, high-performance culture, and are eager to perform."

Burke concluded, "Recent power market developments are certainly notable, and we see multiple drivers underlying a projected long-term acceleration in load growth in many of the geographies we serve. The increase in our potential long-term financial expectations reflects the attractive position provided by our integrated business model. We remain focused on advancing our four strategic priorities of delivering strong and stable earnings, executing a disciplined capital allocation strategy, maintaining balance sheet strength, and supporting a sustainable energy future."

For the quarter ended March 31, 2024, Vistra reported Net Income of $18 million, Net Income from Ongoing Operations¹ of $39 million, and Ongoing Operations Adjusted EBITDA¹ of $813 million. Net Income for the first quarter 2024 decreased $680 million from the first quarter 2023, primarily driven by material unrealized mark-to-market gains recognized in 2023. Ongoing Operations Adjusted EBITDA for the first quarter 2024 increased by $259 million compared to the first quarter 2023 driven primarily by the inclusion of one month of results from the acquisition of Energy Harbor and the expiration of contracts which resulted in higher-than-expected migration of customers to default service providers at rates below prevailing wholesale market prices for the three months ended March 31, 2023.

As of May 8, 2024, Vistra has hedged approximately 95% of its expected generation volumes for the balance of 2024, approximately 80% for 2025, and approximately 50% for 2026. Vistra's comprehensive hedging program, as well as recent forward price curves, support the company's combined 2024 guidance ranges, as well as its combined potential Ongoing Operations Adjusted EBITDA midpoint opportunities for 2025 and 2026. Vistra currently estimates potential midpoint opportunities for Ongoing Operations Adjusted EBITDA to be in the range of $5,000 million to $5,500 million for 2025 and more than $6,000 million for 2026. See footnote 2 for a discussion on Non-GAAP reconciliations.

Share Repurchase Program

As of May 3, 2024:

• Vistra executed ~$3.9 billion in share repurchases since November 2021.
• Vistra had ~347.5 million shares outstanding, representing a ~28% reduction of the amount of the shares outstanding on Nov. 2, 2021.

Vistra expects to spend at least $2.25 billion on share repurchases throughout 2024 and 2025.

Clean Energy Investments

Vistra is focused on the reliability, affordability and sustainability of electricity in the markets in which we operate. Vistra continues to grow its fleet of zero-carbon resources, advancing these interests through cost-effective, strategic investments in solar and battery storage developments and through the acquisition of Energy Harbor.

On March 1, 2024 Vistra closed on the acquisition of Energy Harbor, which added more than 4,000 MW of nuclear generation to its portfolio along with approximately 1 million additional retail customers. Together with Vistra's existing 2,400 MW Comanche Peak Nuclear Power Plant, this acquisition brings Vistra's nuclear capacity to more than 6,400 MW. Notably, in 2022, Comanche Peak applied to extend its operating licenses through 2050 and 2053 for the two-unit facility, an additional 20 years beyond the original licenses. Additionally, in 2023, Perry applied to extend its operating license through 2046, also an additional 20 years beyond the original license. Both processes are advancing as expected.

The Inflation Reduction Act is anticipated to provide the opportunity to realize material benefits to Vistra with respect to its renewables and energy storage projects, as well as provide strong price support via the nuclear production tax credit for its nuclear facilities, including those acquired through the Energy Harbor transaction.

Vistra began construction on two of its three larger Illinois combined solar and energy storage projects, part of the Coal to Solar and Energy Storage Initiative, earlier this year. Vistra intends to remain strategic and disciplined with respect to the timing of investments in renewables and energy storage projects.

Liquidity

As of March 31, 2024, Vistra had total available liquidity of approximately $3,000 million, including cash and cash equivalents of $1,070 million, $1,293 million of availability under its corporate revolving credit facility, and $637 million of availability under its commodity-linked revolving credit facility. Available capacity under the commodity-linked revolving credit facility reflects the borrowing base as of March 31, 2024. Available liquidity excludes $438 million of commitments under the commodity-linked revolving credit facility that were not available to be drawn as of March 31, 2024.³

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 Adj. EBITDA in 2025 and 2026 based on market curves as of May 3, 2024. 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 Adjusted EBITDA opportunities for 2025 and 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 Adjusted EBITDA in such out year periods. Midpoint opportunities exclude any potential benefit from nuclear production tax credit.

3 The accounts receivable securitization program facility was amended to add Energy Harbor and increase the aggregate commitments from $750 million to $1,000 million on April 8, 2024. Borrowings remained at $750 million. The repurchase facility limit remained at $125 million. Borrowings under the facility totaled $125 million.

About Non-GAAP Financial Measures and Items Affecting Comparability

"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 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 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.
