Fitch Ratings has assigned a 'BBB-' with a Recovery Rating of 'RR1' to Vistra Operations Company, LLC's (Vistra Ops) proposed senior secured notes.
Expected use of proceeds is partial funding of the announced acquisition of Cogentrix assets and general corporate purposes, including existing indebtedness repayment.
Fitch has affirmed the Long-Term Issuer Default Ratings (IDRs) of Vistra Corp. (Vistra) and Vistra Ops at 'BB+'. The Rating Outlook for both is Positive. This follows Fitch's 'Corporate Rating Criteria' and 'Sector Navigators Addendum to the Corporate Rating Criteria' update on Jan. 9, 2026.
The proposed notes are expected to have security fall-away provisions, similar to existing secured notes at Vistra Ops, that release collateral if Vistra Ops's senior unsecured notes attain investment-grade status from any two of Fitch, S&P, and Moody's. Accordingly, if Fitch upgrades Vistra's IDR to 'BBB-', Vistra Ops' secured debt would remain unchanged at 'BBB-' to reflect expected collateral fall-away.
Key Rating Drivers
Improved Business Profile: Vistra has significantly improved its business profile through successfully contracting a portion of its existing capacity with strong creditworthy counterparties. Vistra recently announced that it has entered into 20-year PPAs with Meta for more than 2 GW of existing generation. The recently completed acquisition of 2.6 GW of power assets from Lotus Infrastructure Partners and announced acquisition of Cogentrix assets further expands Vistra's scale and geographic diversity.
Stronger Leverage Metrics: Pro forma for the announced and completed acquisitions in 2025, Fitch expects Vistra's gross leverage to improve and remain within the 3.0x-3.5x range from 2026 to 2027, driven by higher wholesale generation EBITDA and strong retail performance. A highly hedged generation portfolio in 2026, improving power prices in Texas, and strong PJM capacity auction results should support wholesale EBITDA growth. Fitch gross debt calculation includes non-recourse debt at Vistra Zero, forward repurchase obligation for acquisition of Vistra Vision's minority interest and reflects 50% equity credit to preferred stock.
Capital Allocation is Key: Fitch expects Vistra to generate more than $3 billion of FCF annually on a run rate basis. Fitch's FCF calculation includes dividends paid to shareholders and capex, including growth capex for already announced new renewable generation, gas fleet uprates in Texas and two natural gas projects in Texas. The substantial FCF affords management flexibility for capital allocation, even after Fitch's assumption of $1 billion annual share repurchases. Fitch expects management to pursue a balanced capital allocation policy that continues to target net leverage below 3.0x.
Tightening Power Markets: Vistra is well positioned to benefit from strong market fundamentals in its largest markets, ERCOT and PJM, as both are experiencing high power demand. ERCOT's peak power demand outlook and forward power curves have strengthened. In PJM, the recently concluded capacity auction cleared at the ceiling price of $333.44/MW-day.
Strong Retail Platform: Vistra's retail business provides revenue stability with relatively high renewal rates and stable margins. Retail margins in the commercial and industrial segments generally remain range-bound during commodity cycles, and residential retail margins are usually countercyclical, given the length and stickiness of the customer contracts. TXU Energy Company LLC, Vistra's largest retail electricity operation in Texas, has demonstrated strong brand recognition, tailored customer offerings and effective customer service, which are driving high customer retention and growth.
Mitigation of Extreme Weather Risks: Vistra has addressed gas deliverability and fuel handling issues, which contributed to sizable financial losses during winter storm Uri in February 2021. Measures include weatherizing its generation fleet, enhancing coal fuel handling, installing dual fuel capabilities at gas steam units, increasing fuel oil inventory at dual fuel sites, contracting additional natural gas storage, and maintaining greater generation length during peak periods. Its fleet demonstrated resilience during recent events such as winter storms Elliot and Heather in December 2022 and January 2024, respectively.
Peer Analysis
Vistra is well positioned relative to NRG Energy Inc. (BB+/Stable) and Calpine Corporation (BBB/Stable) in terms of size, scale and geographic and fuel diversity. Vistra's 44 GW of generation fleet is well diversified by fuel, compared with Calpine's 28 GW, natural gas-heavy portfolio and NRG's 25 GW generation fleet (including the recent acquisition). However, Vistra's portfolio is less diversified geographically, with 57% of its consolidated EBITDA coming from operations in Texas, while Calpine's fleet is more geographically diversified across PJM, Texas and California.
NRG's business profile benefits from its ownership of Vivint, a home security business, which diversifies its revenue stream compared to Vistra. Like Vistra, NRG benefits from its ownership of large and well-entrenched retail electricity businesses in Texas. However, unlike Vistra, NRG has fewer generation assets and serves its retail load from sources other than its own generation. The generation fleet for both NRG and Calpine bears less operational and environmental risk compared to Vistra's portfolio which also has nuclear and coal generation assets.
Fitch projects Vistra's leverage to remain within the 3.0x-3.5x range in 2026-2027, which compares favorably to Calpine's pre-acquisition leverage of around 5.0x and is comparable to NRG's forecast leverage of 3.0x-3.5x.

RATING SENSITIVITIES
Factors that Could, Individually or Collectively, Lead to Negative Rating Action/Downgrade
Vistra and Vistra Ops
Gross debt/EBITDA above 4.0x on a sustained basis;
Weaker power demand and/or higher than expected supply depressing wholesale power prices and capacity auction outcomes in its core regions;
Unfavorable changes in regulatory constructs and markets;
An aggressive growth strategy that diverts a significant proportion of FCF toward merchant generation assets and/or overpriced retail acquisitions.
Factors that Could, Individually or Collectively, Lead to Positive Rating Action/Upgrade
Vistra and Vistra Ops
Demonstrated EBITDA leverage lower than 3.5x on a sustainable basis coupled with a track record of stable EBITDA generation and continued emphasis on an integrated wholesale-retail platform.
Liquidity and Debt Structure
In Fitch's view, Vistra's liquidity is adequate. As of Sept. 30, 2025, the company had approximately $3.7 billion of liquidity, consisting of $602 million cash on hand and $3.1 billion available under revolving facilities. There were no cash borrowings under the commodity-linked facility as of Sept. 30, 2025. Vistra's revolving credit facility agreement has a $3.44 billion commitment expiring in October 2029.
Vistra Ops' first lien secured debt benefits from upstream guarantees from asset subsidiaries under Vistra Ops, which comprise a substantial portion of property, assets and rights owned by Vistra Ops. The secured notes include a security fall-away provision under which collateral securing the notes will be released if Vistra Ops' senior unsecured notes obtain investment-grade ratings from at least two of the three major rating agencies. The fall-away provision will be reinstated if those investment-grade ratings are withdrawn or downgraded below investment grade.
Issuer Profile
Vistra is the largest U.S. independent power generator with 44 GW of capacity. Vistra Retail provides retail electric service to 5 million customers. Its Vistra Zero unit holds a 1.4 GW portfolio of six solar generation and energy storage assets.

ESG Considerations
The highest level of ESG credit relevance is a score of '3', unless otherwise disclosed in this section. A score of '3' means ESG issues are credit-neutral or have only a minimal credit impact on the entity, either due to their nature or the way in which they are being managed by the entity. Fitch's ESG Relevance Scores are not inputs in the rating process; they are an observation on the relevance and materiality of ESG factors in the rating decision.
