Does mild Q1 weather shift ERCOT expectations? How do ERCOT forwards reflect load growth and energy storage impacts?

Mild Q1 weather impacted retail, but the diversified business model provided offsets. ERCOT forwards don't reflect the expected 5-6% compounding load growth, partly due to market focus on near-term weather and the impact of batteries. Management believes the physical world develops slower than market expectations. “I don't even think the market forwards reflect 5% or 6% compounding load. So I think there is a wide disparity in view out there because I think the market had a view that it was going to compound a lot faster than this.”

Has Vistra seen a pause from customers due to PJM regulatory uncertainty (e.g., RBP), similar to Constellation's comments?

The activity level remains high, and discussions are consistent. Customers seek clarity on regulatory issues like RBP and "connect and manage" but know they can't wait. Vistra helps customers navigate complexities, and the pace of engagement is as expected. “The activity level has remained as high as we've ever seen in this. So I don't see a change there. We'd all want clarity. They want clarity, and we're all going to work hard to get it.”

Could you elaborate on the "bridge power" and "distributed gen" options for customers seeking faster time to power?

Bridge power is a workaround when quick grid connection isn't possible. Discussions involve various technologies, but increasingly lean towards gas solutions. The goal is to help customers get started, with the ultimate aim of connecting to the existing grid, which has ample generation capacity. “More of our conversations have been leaning towards the use of gas in these bridge power solutions. And obviously, that's something we're comfortable with. But the customers ultimately are looking to scale up. And so it's more about how do you get started.”

Executive summary

Vistra Corp. Q1 FY26 — Record Adjusted EBITDA and Strategic Growth Initiatives

Vistra delivered a record first quarter, driven by strong generation performance and strategic acquisitions, despite mild weather impacting retail. The company is actively pursuing organic development opportunities and remains confident in its outlook, supported by hedging and disciplined capital allocation. Management is focused on navigating regulatory complexities and meeting growing customer demand, particularly from hyperscalers, through flexible and cost-effective solutions.

Highlights

Achieved record Q1 adjusted EBITDA of $1.5 billion, up 20% YoY.
Natural gas fleet performed at 97% commercial availability and nuclear fleet at 100% during Winter Storm Fern.
Accelerated share repurchases, deploying approximately $525 million in the first four months of the year.
Received investment-grade rating upgrade from Fitch Ratings, triggering lien fallaway provisions.
Secured 5,500 MW Cogentrix natural gas generation portfolio acquisition and 2,600 MW long-term PPAs with Meta.

Concerns

Extremely mild weather in ERCOT during Q1, the second warmest first quarter since 1950, partially offsetting retail performance.
ERCOT forward curves do not fully reflect Vistra's load growth expectations of 5-6% CAGR through 2030.
Uncertainty around FERC PJM colocation rules and the ERCOT batch process for load interconnection queues.

Risks & headwinds

Mild weather impact on retail segment Q1 2026

ERCOT Q1 was the second warmest since 1950.

Mitigation:Diversified integrated business model (generation offsets retail impact).

ERCOT forward curves not reflecting load growth Near-term future periods

Forwards do not reflect 5-6% compounding load growth.

Mitigation:Management believes the market will eventually catch up as physical development progresses.

Regulatory uncertainty in PJM (colocation rules, RBP) Ongoing

FERC PJM colocation rules require tariff work and clarification; RBP uncertainty.

Mitigation:Engaging with policymakers and customers to clarify rules; contracting around uncertainties; advocating for faster load interconnection.

ERCOT load interconnection queue inefficiencies Through 2030

Batch 0 could be as large as 100 GW, while real data center growth is estimated at 10-15 GW by 2030.

Mitigation:Advocating for higher commitment requirements in the load queue to prioritize real projects and speed up connections.

Q&A highlights

Will FERC's PJM colocation rules open up more Meta-like deals, impact combining new/existing capacity, and extend beyond nuclear?

Management is encouraged by FERC's clear directive for PJM to support colocation. While tariff details are being sorted, customer discussions are ongoing for both gas and nuclear sites. Colocation is seen as crucial for speed to power and meeting demand, and FERC is expected to act quickly to clarify rules.

“FERC's colocation order in December made it very clear that colocation is something that PJM must support. And so the filings are now just trying to sort through what the rules of the road are, and we do expect FERC to be motivated to act quickly on that.”

Detailed narrative

Q1 Performance and Market Volatility

Vistra achieved a record $1.5 billion in adjusted EBITDA for Q1 2026, a 20% increase year-over-year. This strong performance was driven by the generation segment, which contributed $1.426 billion, benefiting from high realized revenues and PJM capacity revenues. The quarter saw volatile weather, including a mild ERCOT period (second warmest Q1 since 1950) interrupted by Winter Storm Fern, during which the natural gas fleet maintained 97% commercial availability and the nuclear fleet 100%.

Load Growth and Market Fundamentals

The company observes a structurally improved demand environment with elevated load growth, particularly from hyperscalers and increased industrial activity. ERCOT is projected to experience at least 5-6% annual load growth through 2030, and PJM 2-3%. Management believes overall load growth will outpace peak demand, leading to higher utilization of existing infrastructure and supporting lower unit costs for customers, as fixed costs are spread over more volumes.

Organic Development Opportunities

Vistra has approximately 4,500 MW of organic development opportunities recently completed or in process, including contracted renewables (Oak Hill 1 & 2, Pulaski, Newton), thermal additions (coal-to-gas conversions at Coleto Creek and Miami Fort), Texas gas expansions, and a PJM nuclear uprate supported by Meta PPAs.

These projects are expected online by 2028 and represent cost-effective capacity additions, with additional gigawatts in the pipeline, including uprates at Comanche Peak (>200 MW) and PJM gas sites (~300 MW).

Capital Allocation and Shareholder Returns

The company expects to generate over $10 billion in cash from 2026-2027. Approximately $3 billion is allocated to equity holders (share repurchases, dividends) and $4 billion to accretive growth investments (Cogentrix, Permian gas, PJM nuclear uprate, Oak Hill 2). Vistra accelerated share repurchases in the first four months of the year, deploying $525 million, and has $1.475 billion remaining in authorization.

The company also achieved investment-grade ratings from Fitch and S&P, triggering lien fallaway provisions on senior secured debt.

PJM Colocation and Regulatory Clarity

Vistra is encouraged by FERC's colocation order in PJM, which mandates support for colocation with existing and new generation to meet demand. While tariff work and rule clarification are ongoing, customer discussions for bilateral contracts continue in parallel. The company emphasizes that colocation offers a speed-to-power advantage and helps address affordability and resource adequacy by utilizing existing capacity.

ERCOT Load Queue and Forwards

Management acknowledges the mild Q1 weather in ERCOT and its impact on retail, but notes the integrated model's resilience. They believe ERCOT forwards do not fully reflect the expected 5-6% compounding load growth, partly due to market focus on near-term weather and the impact of battery additions.

Vistra advocates for higher commitment bars in the load queue to ensure real projects are prioritized and transmission is allocated efficiently.

Bridge Power and Flexible Solutions

To address the need for speed to power, Vistra is engaging in discussions with customers regarding "bridge power" solutions, often involving gas-based technologies, to provide interim power while awaiting grid connections. The company notes that customers are increasingly willing to consider flexible solutions, and regulatory processes need to catch up to customer needs to facilitate faster connections and product choices that match flexibility criteria.
