Vistra Corp. Achieves Investment-Grade Status with Fitch Following S&P
Vistra Corp. announced on Tuesday that Fitch Ratings has upgraded its long-term solvency rating to investment-grade (BBB-), marking the second endorsement from a major credit agency following an upgrade by S&P Global Ratings in December 2025.
Rationale Behind Fitch's Upgrade
Fitch Ratings justified its upgrade of Vistra's long-term solvency rating to BBB- by pointing to the company's improved business profile, strong credit metrics, favorable capital allocation policy, and enhanced market fundamentals. This upgrade follows that of S&P Global Ratings, which had elevated Vistra's solvency rating to investment-grade status on December 2, 2025. CEO Jim Burke stated that these upgrades reflect 'the consistent execution of our strategy and our ongoing focus on balance sheet strength.'
Strengthening of Vistra's Credit Profile
The enhancement of Vistra's credit profile is based on four main elements: sustained generation of free cash flow in all market conditions, disciplined capital allocation and reduction of balance sheet leverage, an increasingly geographically and energetically diversified production portfolio with a significant dispatchable component, and increased visibility and stability of the earnings profile, supported by recently announced long-term power purchase agreements (PPAs) with Amazon and Meta. Vistra anticipates that the investment-grade ratings from S&P and Fitch will strengthen its access to capital markets and progressively reduce its borrowing costs.
