Vistra Corp reported second-quarter adjusted EBITDA of $1.767 billion, up 30% from $1.35 billion a year earlier, as record power demand lifted generation earnings.
"The business continues to perform very well, and we remain on track to achieve another record result in 2026," Chief Executive Officer Jim Burke said.
Generation EBITDA jumped 68% to $994 million on favorable hedging, higher PJM capacity revenues, optimized flexible gas generation and the Martin Lake Unit 1 restart. Retail EBITDA rose 2% to $773 million, while average realized power prices climbed about 5% per megawatt-hour.
The company reaffirmed 2026 adjusted EBITDA guidance of $6.8 billion to $7.6 billion and free cash flow before growth of $3.925 billion to $4.725 billion, expecting to deliver at or above the midpoint. Shares fell 0.56% to $140.59.
Both PJM and ERCOT set new all-time summer peak loads in July, with PJM exceeding 168 gigawatts and ERCOT topping 91 gigawatts. Vistra's diversified fleet achieved more than 97% commercial availability during the heat waves, after completing three nuclear refueling outages and 92 gas and coal planned outages in the spring.
Vistra announced a partnership with KKR, NVIDIA and the Kuwait Investment Authority to launch Helix digital infrastructure, a data center development platform where Vistra will act as preferred power partner. The company will commit up to $1 billion, with amounts above $500 million tied to project milestones.
Management maintained its 2027 adjusted EBITDA midpoint opportunity of $7.4 billion to $7.8 billion, though it is trending toward the lower end because of softer ERCOT forward prices. The Cogentrix acquisition and Meta power purchase agreements, excluded from that range, could add roughly $700 million.
The company plans to allocate $4.5 billion to $5 billion to growth investments through 2027, including Cogentrix, Permian peakers, nuclear power purchase agreements and Helix. With more than $10 billion of available cash in 2026 and 2027, Vistra retains $2 billion to $2.5 billion for additional discretionary allocation. Since November 2021, it has retired about 171 million shares at an average cost of $38 each, returning more than $6.5 billion to shareholders.
Chief Financial Officer Kris Moldovan said the remaining $1.2 billion share repurchase authorization is expected to be exhausted by the end of 2027, with management and the board open to expanding the program if market conditions warrant.
Near-term risks include ERCOT forward price softness from battery additions and regulatory uncertainty around Texas data center audits and PJM market design. Burke said the audit should thin an overstated interconnection queue of more than 400 gigawatts proposed against 12 to 15 gigawatts expected, and that Vistra's Comanche Peak project, targeted for energization at the end of 2027, is not affected.
The results confirm Vistra's position as a primary beneficiary of data center-driven power demand, with the Helix partnership broadening its access to that market. Investors will watch the Q3 earnings call for updated 2027 guidance, including the potential $700 million contribution from the Cogentrix acquisition and Meta power purchase agreements.
