Vistra Stock Rises 10.6% to $124.80 on Results Day, on 1.6 Times Its Usual Volume

1What Vistra reported

Vistra Corp. (NYSE: VST) closed up 10.6% on November 6, 2026, the day it released its third quarter results. The company filed the release with the SEC at 7:01 a.m. ET, before the market opened. Each figure below is for the quarter ended September 30, 2026, with the year earlier figure beside it when the release prints one.

• Net income: $1,140 million, against $652 million a year earlier. Net income is profit after all costs and taxes.
• Sales: operating revenues of $6,347 million, against $4,971 million a year earlier.
• Adjusted profit: Ongoing Operations Adjusted EBITDA of $2,378 million, against $1,581 million a year earlier. This is a profit measure the company adjusts to leave out some costs and gains, and it leaves out the Asset Closure segment, which the company reports separately.
• One time item, hedge gain: net income includes an unrealized gain from hedges of $559 million. Hedges are contracts that lock in future power prices, and the company expects these to settle in future years, so the gain is on paper until then.
• One time item, write-down: the quarter includes an impairment of long-lived assets of $269 million, against $5 million a year earlier. An impairment is a write-down of what the company's books say an asset is worth. The release names a partial impairment of the Moss Landing 350 facility.
• Guidance for 2026: the company raised the midpoint and narrowed the range for 2026 Ongoing Operations Adjusted EBITDA to $7.1 billion to $7.5 billion. Guidance is the company's own stated range for its future results. It did the same for Ongoing Operations Adjusted FCFbG, short for adjusted free cash flow before growth, a cash measure taken before spending on growth, and now gives a range of $4.3 billion to $4.7 billion.
• Guidance for 2027: the company gave its first ranges for the year: Ongoing Operations Adjusted EBITDA of $7.7 billion to $8.5 billion and Ongoing Operations Adjusted FCFbG of $4.3 billion to $5.1 billion.
• Share repurchases: the board authorized an additional $1.5 billion of repurchases, which the company expects to use by year-end 2028. A repurchase is when a company buys its own shares.
• Deal: in October 2026 the company closed its acquisition of Cogentrix Energy, which adds natural gas-fueled power plants to its fleet.
