What is Vistra's view on long-term contracting, new build costs (e.g., '90% range'), and potential premiums for existing generation?

Jim Burke highlighted the dilemma of current ERCOT wholesale prices ($30/MWh year-to-date) being too low to incentivize new builds, while equipment costs have doubled or tripled. He noted that large load customers are contracting with existing assets at a premium because it's still a discount to new build costs. Vistra sees continued interest from customers for both new and existing capacity solutions. “Year-to-date, ERCOT wholesale prices have been $30 a megawatt hour. They were $30 a megawatt hour last year. $30 is not going to get new stuff built. That's part of the dilemma.”

How do the PJM and ERCOT markets compare in terms of contract discussions and regulatory maturity for large load customers?

Jim Burke explained that ERCOT is currently less tight than PJM, with ERCOT taking a more deliberate approach to study processes. Stacey Dore added that both markets have regulatory uncertainties, but customers are still highly interested in expanding in both. She noted that customers don't need 'perfect clarity' to contract and are using contractual provisions to manage risks. “The 2 markets are starting in slightly different places. So as you know, with Texas and you can see it in the forwards, you can see it in the real-time settles. The Texas market is just a lot less tight at the moment than the PJM market.”

What are Vistra's thoughts on the FERC IRAS proposal, particularly regarding data center flexibility and potential mandates?

Jim Burke stated Vistra prefers a 'carrot approach' with incentives for customer flexibility rather than a 'stick approach' that risks disconnection or requires curtailment before paid curtailment. Stacey Dore added that Vistra does not support 'bring your own new capacity mandates' and believes the market should drive incentives. She noted concerns about the proposal but also that it might drive more interest in co-location with existing resources. “Some of these dockets and we understand why go much more to a stick approach, and it effectively says if you don't do these things, you're at risk of disconnection. I think that's a much more blunt instrument.”

Risks & headwinds

Softening ERCOT power prices near-term

ERCOT forward curves are meaningfully lower and year-to-date ERCOT wholesale prices have been $30 a megawatt hour.

Mitigation:Comprehensive hedging program and downside protection afforded by the nuclear PTC (for 2027 guidance). Long-term fundamentals expected to improve.

Texas data center audit and interconnection delays near term

Audit is going to probably pause some of the reviews for a couple of months.

Mitigation:Vistra supports thinning the queues for realistic development; Comanche Peak project not expected to be affected (energizing end of 2027). Policymakers are motivated to get the audit done timely.

Insufficient power prices for new generation builds current

ERCOT wholesale prices have been $30 a megawatt hour... $30 is not going to get new stuff built.

Mitigation:Large load customers are contracting with existing assets at a premium; Vistra has existing base load position.

FERC's proposed Interconnection and Transmission Planning (IRAS) rule upcoming

Concerns about it (potential for 'stick approach' and required curtailment before paid curtailment).

Mitigation:Vistra will weigh in on the proposal, advocating for incentives for flexibility; potential to drive more interest in co-location with existing resources.

What to watch in Q3 FY26

Texas data center audit outcome

next quarter

Current Audit expected to pause reviews for a couple of months; no moratorium currently

Target Clarity on audit timeline and impact on interconnection queue

Why it matters

The audit will determine the pace and scale of data center load additions in ERCOT, impacting future demand and Vistra's project timelines.

I do think in the near term, I think the audit is going to probably pause some of the reviews for a couple of months. We don't know exactly the time frame.

Q&A highlights

How do Texas data center audits impact Vistra's projects and the broader market, especially given current ERCOT forward curve impacts?

Jim Burke stated that Vistra's long-term ERCOT load forecast (115-120 GW by 2030) remains unchanged despite queue growth. He believes the audit will pause reviews for a few months but doesn't expect it to affect their Comanche Peak project (energizing end of 2027). Vistra supports thinning the queues to ensure realistic projects move forward, as the current 400 GW queue is overstated.

“I do think in the near term, I think the audit is going to probably pause some of the reviews for a couple of months. We don't know exactly the time frame. The key project that we have in our portfolio at Comanche Peak, we're looking to energize at the end of 2027. We don't see that being affected at this point.”

Detailed narrative

Market Demand and Operational Excellence

Vistra is observing a structurally improved demand environment in PJM and ERCOT, with both markets hitting new all-time summer peak loads in July (PJM over 168 GW, ERCOT over 91 GW). The company successfully completed its annual spring maintenance cycle, including planned refueling outages for 3 nuclear units and 92 planned outages for gas and coal fleets, achieving over 97% commercial availability during recent heat waves.

Data Center Growth and Strategy

Data center development activity remains strong, with Vistra actively negotiating with large load customers. The company believes its diversified fleet, development capabilities, retail franchise, and commercial team position it well to capitalize on these opportunities. Vistra supports policymakers' efforts to thin ERCOT's data center queues to ensure realistic development and grid reliability, noting that current ERCOT wholesale prices ($30/MWh year-to-date) are insufficient for new builds.

Helix Digital Infrastructure Partnership

Vistra announced a partnership with KKR, NVIDIA, and the Kuwait Investment Authority to form Helix Digital Infrastructure. Vistra will commit up to $1 billion over time, with $500 million subject to milestones, and will serve as the preferred power partner.

This platform aims to provide a 'rack to grid' solution for data centers, leveraging Vistra's expertise and generation capabilities, while retaining optionality for Vistra to develop projects independently.

Capital Allocation and Shareholder Returns

Vistra expects to generate over $10 billion of available cash in 2026 and 2027. Approximately $3 billion is allocated to equity holders through share repurchases and dividends, with $1.2 billion of share repurchase authorization remaining, expected to be exhausted by end of 2027. The company has returned over $6.5 billion to shareholders since November 2021, exceeding its $6 billion target by year-end 2026.

Growth Investments and Credit Ratings

Vistra plans to allocate $4.5 billion to $5 billion to accretive growth investments, including the Cogentrix acquisition, Permian gas units, PJM Nuclear uprates with Meta PPAs, Oak Hill 2 solar facility, and the Helix commitment. The company aims to achieve mid-investment-grade credit ratings from all three major agencies, primarily through disciplined EBITDA growth, and will consider debt paydown as necessary.

Regulatory Landscape and Market Dynamics

Vistra is actively engaged in regulatory processes in its key markets, supporting efforts to ensure grid reliability and affordability. The company notes that while ERCOT power prices have softened due to increased supply (including batteries) and weather, long-term growth fundamentals remain on track, driven by industrial reshoring, electrification, population growth, and broader economic expansion, in addition to data centers.
