Vistra Corp. VST used its second-quarter 2026 earnings call to reinforce a power-demand outlook driven by data centers and broader load growth, while acknowledging softer ERCOT pricing.
Management sharpened 2027 framing, expanded on Helix and emphasized capital-allocation flexibility.
VST Maintains Its 2026 Outlook
Executive vice president and CFO Kristopher Moldovan reaffirmed 2026 adjusted EBITDA guidance of $6.8 billion to $7.6 billion and adjusted free cash flow before growth of $3.925 billion to $4.725 billion. He expects results at or above both midpoints.
President and CEO James Burke highlighted second-quarter adjusted EBITDA of $1.767 billion, up more than 30% year over year. Fleet commercial availability exceeded 97% during recent heat in Texas and PJM.
VST’s second-quarter 2026 earnings of $1.80 per share topped the Zacks Consensus Estimate of $1.54. However, revenues of $4.02 billion missed the Zacks Consensus Estimate of $6.29 billion.
Vistra Sees Data Center Demand Holding
The CEO maintained Vistra's view of annual load growth of at least 4% to 6% in ERCOT and 2% to 3% in PJM through 2030. He expects data centers to become a larger driver from 2028.
A Wells Fargo analyst pressed management on Texas data center audits and Batch Zero delays. CEO Burke said reviews could pause for a few months, but Vistra does not expect its late-2027 Comanche Peak project to be affected.
Chief strategy and sustainability officer Stacey Dore said Vistra remains in active discussions across multiple ERCOT and PJM sites. She added that customers are still willing to contract before every regulatory detail is settled.
VST Flags a Softer 2027 ERCOT Setup
CFO Kristopher Moldovan said current ERCOT forward curves are meaningfully below levels used for Vistra's 2027 midpoint opportunity range of $7.4 billion to $7.8 billion. Higher PJM prices, hedges and nuclear production tax credit protection support maintaining the range.
A Wolfe Research analyst asked about the 2027 bias. Moldovan clarified that those offsets do not fully cover the ERCOT headwind and said Vistra is trending toward the lower end of the range.
Cogentrix and the Meta power purchase agreements remain excluded. The CFO said prior disclosures support roughly $700 million of additional midpoint opportunity from those items before other impacts. He expects a 2026 and 2027 guidance update on the third-quarter call, subject to Cogentrix's closing timetable.
Vistra Uses Helix To Expand Its Deal Funnel
CEO James Burke described Helix as an added channel for data center opportunities, not a required route. Vistra has committed up to $1 billion, with funding above $500 million tied to milestones, and will serve as Helix's preferred power partner.
Wolfe Research and Morgan Stanley analysts asked about Helix's pipeline and economics. Chief strategy and sustainability officer Stacey Dore said the platform can draw from Vistra's sites and bring new inbound customer opportunities.
Dore said any Vistra power project pursued through Helix must meet the company's mid-teens return targets. Helix can also take a different capital-risk profile where Vistra does not provide the power.
VST Keeps Capital Allocation Flexible
CFO Moldovan said Vistra expects more than $10 billion of available cash across 2026 and 2027. About $3 billion is allocated to equity holders and $4.5 billion to $5 billion to growth, leaving $2 billion to $2.5 billion for further allocation.
A Goldman Sachs analyst asked about faster buybacks. Moldovan said the remaining $1.2 billion authorization should be exhausted no later than year-end 2027 and management has flexibility to seek additional authorization.
The CFO also reiterated Vistra's goal of mid-investment-grade ratings at three major agencies. He said disciplined EBITDA growth is the primary path, with debt reduction available when appropriate.
Vistra Keeps Focus on Execution
CEO Burke closed by emphasizing reliable fleet performance, disciplined development and a realistic view of power-market supply and demand as policy debates continue.
Management paired confidence in long-term load growth with caution around ERCOT pricing, regulatory timing and the pace at which data center demand converts into contracted load.
