Vistra Corp is the largest competitive power generator in the United States, with approximately 40.7 GW of generation capacity across natural gas, nuclear, coal, solar, and battery storage. The company is also one of the largest competitive retail electricity providers in the country, serving approximately 5 million customers under brands including TXU Energy, Ambit Energy, and Homefield Energy across 20 states and the District of Columbia. CEO Jim Burke has led the company since December 2020. Vistra is a Fortune 500 company and joined the S&P 500 in 2024.
Vistra emerged from bankruptcy in October 2016 as the successor to the competitive generation and retail businesses of Energy Future Holdings (EFH), itself the renamed remnant of TXU Corp after one of the most consequential private equity failures in history. In 2007, KKR, TPG, and Goldman Sachs acquired TXU in a $45 billion leveraged buyout — the largest LBO ever completed at the time — betting that natural gas prices would stay elevated and that coal and gas power plants in Texas would generate strong cash flows. The shale revolution destroyed that thesis. Natural gas prices collapsed, the generation fleet's economics deteriorated, and EFH accumulated over $40 billion in debt it could not service. The company filed Chapter 11 in April 2014. The reorganization separated the regulated transmission and distribution business (Oncor, now owned by Sempra) from the competitive generation and retail operations, which emerged as Vistra in October 2016 with roughly $24 billion in first-lien debt converted to equity and approximately $33.8 billion in total obligations discharged.
The company that emerged from bankruptcy has been substantially transformed by the March 2024 acquisition of Energy Harbor, which added approximately 4,000 MW of nuclear generation in Ohio and Pennsylvania and approximately one million retail customers. Combined with Vistra's pre-existing Comanche Peak nuclear plant in Texas (approximately 2,400 MW), the acquisition made Vistra the second-largest owner of competitive nuclear capacity in the United States after Constellation Energy. The Energy Harbor deal, the IRA's nuclear production tax credits under Section 45U, and rising power demand from data centers drove a dramatic rerating of Vistra's stock — from approximately $25 per share in early 2023 to over $140 at its 2025 peak.
Vistra's retail business sells electricity directly to residential, commercial, and industrial customers in deregulated markets. TXU Energy is the flagship brand and the leading competitive electricity provider in Texas, where ERCOT deregulation gives customers the ability to choose their electricity supplier. Ambit Energy, acquired separately, adds approximately 1.1 million customers through a direct-selling model using independent consultants and is the largest energy-focused direct seller in the country. Together with Homefield Energy, legacy Dynegy retail operations, and other brands, the portfolio serves customers across 20 states and DC. The retail business is strategically integrated with Vistra's generation fleet: selling power to its own retail customers reduces the company's net exposure to spot wholesale price volatility, because a price spike that hurts retail gross margin is simultaneously offset by higher generation revenues. This natural hedge is central to how Vistra manages risk in the uncapped ERCOT market.
Vistra's generation fleet spans natural gas (~59% of capacity, approximately 24 GW), coal (~21%, approximately 8.5 GW), nuclear (~16%, approximately 6.4 GW), and solar plus battery storage (~5%). Natural gas combined-cycle and peaking plants are concentrated in Texas (roughly 19.6 GW in ERCOT) and the PJM interconnection. The coal fleet is a legacy position that Vistra has been winding down over time as individual units reach the end of their economic lives. Battery storage capacity of approximately 1,020 MW makes Vistra the second-largest battery storage operator in the United States; its Moss Landing Energy Storage Facility in California, at 400 MW and 1,600 MWh, is among the largest in the world. Vistra has a pending acquisition of Cogentrix Energy, which would add approximately 5,500 MW of natural gas capacity across 10 modern facilities and bring the total fleet toward 50,000 MW.
Vistra Vision is a subsidiary holding company formed to consolidate the company's nuclear generation, clean energy assets, and associated retail operations. The nuclear fleet includes Comanche Peak Nuclear Power Plant in Glen Rose, Texas (approximately 2,400 MW, two AP-1000 pressurized water reactors), and the three facilities acquired from Energy Harbor: Perry Nuclear Power Plant in Ohio (approximately 1,254 MW), Davis-Besse Nuclear Power Station in Ohio (approximately 908 MW), and Beaver Valley Power Station in Pennsylvania (approximately 1,872 MW across two units). Vistra Vision also holds the company's solar portfolio and the Vistra Zero clean energy development platform, which is building out renewable generation and battery storage capacity. Long-term nuclear power purchase agreements signed with Amazon Web Services and Meta commit Vistra's zero-carbon output to hyperscale data center operators, following the model established by Constellation Energy's Microsoft deal.
Energy Harbor was the competitive generation and retail subsidiary that emerged from the FirstEnergy Solutions bankruptcy in 2020. Its nuclear plants — Perry, Davis-Besse, and Beaver Valley — had been on the brink of closure in 2018 and 2019 due to low power prices and the economic challenge of running nuclear plants in competitive markets against cheap natural gas. The plants were saved by Ohio House Bill 6, which established a customer surcharge to subsidize their operation, though that legislation subsequently became mired in a major bribery scandal involving Ohio utility lobbyists and state officials. Despite the political controversy, the plants continued operating under FERC oversight.
Vistra announced the acquisition of Energy Harbor on March 6, 2023, and closed the transaction on March 1, 2024, following FERC approval. The deal structure was $3.0 billion in cash plus a 15% equity interest in the newly formed Vistra Vision subsidiary — an implied total deal value of approximately $6.8 billion. Energy Harbor's private equity owners received the 15% Vistra Vision stake rather than cash for that portion, giving them ongoing exposure to the nuclear assets' future upside.
The timing of the acquisition was well-calibrated. The IRA's Section 45U nuclear production tax credit, enacted in August 2022, provides up to 1.5 cents per kilowatt-hour for zero-emission nuclear generation through 2032. For Vistra's approximately 6.4 GW nuclear fleet operating at high capacity factors, the credit is worth hundreds of millions of dollars annually and materially changes the economics of owning competitive nuclear assets. Vistra acquired Energy Harbor knowing those credits would apply, and the earnings trajectory reflected in Vistra's FY2026 EBITDA guidance of $6.8 to $7.6 billion is substantially shaped by the nuclear PTC flowing through the fleet.
Vistra's primary financial metric is ongoing operations adjusted EBITDA, which management uses to capture normalized earnings from the generation and retail businesses while excluding mark-to-market movements on hedges and other non-recurring items. FY2024 ongoing operations adjusted EBITDA was $5.66 billion, up approximately 37% from $4.14 billion in FY2023 and beating Vistra's own guidance by approximately $856 million. GAAP net income was $2.81 billion. The FY2024 result reflected a full year of Energy Harbor contribution (the deal closed March 1, 2024), strong ERCOT power prices, and the initial benefit of Section 45U nuclear production tax credits.
Cash generation has been substantial. Operating cash flow was $4.56 billion in FY2024, and Vistra has used its cash flows aggressively for capital return to shareholders. The company committed approximately $3.75 billion to share repurchases across 2024 and 2025, with an ongoing program targeting at least $1 billion in annual buybacks. Annual dividends are targeted at $300 million. Net leverage is targeted below 3.0x, and Vistra repurchased approximately 98% of the beneficial interests in its Tax Receivable Agreement — a legacy structure from the bankruptcy reorganization — simplifying the capital structure and eliminating a significant future cash obligation.
For FY2025, Vistra has guided to ongoing operations adjusted EBITDA of $5.7 to $5.9 billion. For FY2026, the company has initiated guidance of $6.8 to $7.6 billion — a step-up driven by the full-year contribution of nuclear PTC credits, contracted data center power agreements, and continued ERCOT fleet optimization. Adjusted free cash flow before growth investment is guided to $3.3 to $3.5 billion in FY2025 and $3.9 to $4.7 billion in FY2026.
Vistra's strategy centers on three converging trends: the retirement of coal and aging gas plants reducing available dispatchable generation; surging electricity demand from data centers and AI infrastructure; and the IRA's financial support for zero-emission nuclear generation. The company's integrated retail-generation model is designed to capture value across the full supply chain from fuel to electron to customer, with the ERCOT market as the primary arena. Vistra has committed to adding over 2,000 MW of new capacity in Texas between 2024 and 2028, primarily through advanced natural gas combined-cycle units at existing sites, which can be permitted and constructed faster than greenfield locations.
The data center opportunity is central to Vistra's medium-term case. Long-term power purchase agreements with Amazon Web Services and Meta for nuclear output establish the template: hyperscale data center operators need 24/7 carbon-free power for Scope 2 emissions accounting, nuclear provides exactly that, and Vistra's competitive nuclear fleet can contract directly without going through regulated utilities or PJM capacity auctions. Management projects 5 to 6% annual load growth in ERCOT through 2030, driven substantially by data center expansion in Texas. If that growth materializes, it supports both higher wholesale power prices and direct contracted load for Vistra's fleet.
ERCOT price volatility is the most direct earnings risk Vistra faces. Texas operates without a capacity market and without a price cap above $5,000 per MWh, meaning wholesale electricity prices during heat waves, cold snaps, or periods of tight supply can spike dramatically. The February 2021 winter storm (Uri) created both windfall earnings for some generators and catastrophic losses for others depending on their hedge positions and fuel supply arrangements. Vistra's integrated retail-generation model mitigates but does not eliminate this exposure: unhedged generation capacity of 2 to 2.5 GW is directly exposed to spot prices, and the retail book's cost basis can diverge sharply from spot in extreme events. Regulatory responses to extreme ERCOT pricing events — including potential market reforms, price cap changes, or reliability requirements — are an ongoing policy risk.
The IRA's Section 45U nuclear production tax credit is material to Vistra's current earnings and the FY2026 guidance step-up. The credit runs through 2032 and is subject to a phase-out at higher power prices. Any legislative change, court ruling, or regulatory interpretation that reduces the credit's value would directly affect Vistra's nuclear fleet economics and the earnings trajectory embedded in current guidance. The nuclear fleet also carries operational risk: unplanned outages at any of the five nuclear stations reduce generation output and PTC earnings simultaneously, and the plants require continuous heavy maintenance investment and regulatory compliance to maintain operating licenses. How Vistra manages the balance between aggressive capital return to shareholders and the reinvestment required to keep the nuclear fleet running reliably over the coming decade is a key question for the long-term investment case.
