Management Comments

• Vistra is a leader in transforming the energy landscape, with an unyielding focus on reliability, affordability, and sustainability.
• The company safely operates a reliable, efficient power generation fleet of natural gas, nuclear, coal, solar, and battery energy storage facilities while taking an innovative, customer-centric approach to its retail business.

Industry Context

This agreement highlights a growing trend in the energy sector towards long-term, stable contracts for carbon-free power, driven by corporate sustainability goals and the broader energy transition. It positions Vistra favorably in the competitive landscape by securing a significant portion of its nuclear output with a creditworthy counterparty, providing revenue stability in a volatile market.

Comparison to Industry Standards

• The 20-year term with options for an additional 20 years is a robust long-term contract, providing greater revenue certainty compared to shorter-term market-based sales common in the industry.
• Securing an investment-grade customer for 1,200 MW of nuclear power is a significant achievement, demonstrating strong demand for reliable, carbon-free baseload generation, which is often sought after by large corporations for their ESG commitments.
• While specific comparable projects are not detailed in the filing, long-term PPAs for large-scale carbon-free generation, such as those seen with major tech companies or industrial users, typically command premium pricing or provide enhanced revenue stability compared to merchant power sales.

Stakeholder Impact

• Shareholders: Expected positive financial impact through increased Adjusted Free Cash Flow before Growth and enhanced revenue stability.
• Customers: The large, investment-grade customer secures a long-term supply of carbon-free power, supporting their sustainability goals.
• Employees: Stable operations at the Comanche Peak Nuclear Power Plant are supported by this long-term contract.
• Environment: The agreement promotes the use of carbon-free nuclear power, contributing to decarbonization efforts.

Next Steps

• Begin power delivery in the fourth quarter of 2027.
• Ramp power delivery to full capacity by 2032.

Key Dates

Recommendation

The 20-year power purchase agreement for 1,200 MW of carbon-free nuclear power with a large, investment-grade customer significantly de-risks Vistra's future revenue streams and provides substantial financial accretion (8-10% incremental Adjusted Free Cash Flow before Growth). This long-term contract enhances the company's stability, aligns with growing demand for sustainable energy, and positions Vistra favorably for consistent performance, making it a strong buy for investors seeking long-term value and stability in the energy sector.
