Vistra Posts 30% EBITDA Growth in Q2, Reaffirms Guidance as Data Center Demand Surges
The power generation giant delivered $1.77 billion in second-quarter adjusted EBITDA and announced a $1 billion commitment to new digital infrastructure venture Helix.
Strong Quarter Amid Record Peak Demand
Vistra Corp. reported second-quarter adjusted EBITDA of $1.767 billion, representing a more than 30% increase compared to $1.35 billion in the same period last year (earnings call, 2026-08-07). The results came as both PJM and ERCOT hit new all-time summer peak loads in July, with PJM reaching over 168 gigawatts and ERCOT exceeding 91 gigawatts.
The company's generation business contributed approximately $994 million of adjusted EBITDA in the quarter, up from $593 million a year earlier, driven by favorable hedging activity and higher capacity revenues in PJM. Retail operations added $773 million, compared to $756 million in the prior-year quarter.
President and CEO Jim Burke attributed the performance to the company's "7,000 team members across the organization" and noted that the fleet achieved "commercial availability of over 97% across the entire fleet" during recent heat waves (earnings call, 2026-08-07).
Guidance Maintained Despite ERCOT Softness
Vistra reaffirmed its 2026 adjusted EBITDA guidance range of $6.8 billion to $7.6 billion and adjusted free cash flow before growth guidance of $3.925 billion to $4.725 billion. CFO Kris Moldovan said the company is "confident in our ability to deliver at or above the midpoint of these ranges" given first-half performance.
For 2027, the company maintained its adjusted EBITDA midpoint opportunity range of $7.4 billion to $7.8 billion, despite "meaningfully lower" ERCOT forward curves compared to late 2025. Moldovan cited offsetting factors including higher PJM prices, hedging programs, and nuclear production tax credit protections. The 2027 range excludes contributions from the pending Cogentrix acquisition and premium pricing from Meta power purchase agreements.
Helix Partnership and Growth Strategy
Vistra announced a partnership with KKR, NVIDIA, and the Kuwait Investment Authority as a founding investor in Helix Digital Infrastructure, a new platform focused on providing integrated power and infrastructure solutions for data centers. The company committed up to $1 billion to be invested over time, with amounts above $500 million subject to milestone achievements.
Under the arrangement, Vistra will serve as the "preferred power partner" for Helix development projects while retaining "significant optionality to develop projects" independently (earnings call, 2026-08-07).
Burke characterized demand trends as "structurally improved," estimating annual load growth of "at least 4% to 6% in ERCOT and 2% to 3% in PJM through 2030." He noted that data center development represents only part of the growth story, with "industrial reshoring, increasing electrification, population growth" and economic expansion also driving demand.
Capital Allocation Accelerates
Moldovan reported that since initiating its buyback program in November 2021, Vistra has retired approximately 171 million shares at an average cost of about $38 per share. The company has returned over $6.5 billion to shareholders through repurchases through August 3, exceeding its original target of $6 billion by year-end 2026.
The company expects to generate more than $10 billion of available cash in 2026 and 2027, with approximately $3 billion allocated to equity holders through repurchases and dividends, and $4.5 billion to $5 billion earmarked for growth investments.
