Vistra rises 10.8% after DOE offers $4.2 billion conditional loan to expand nuclear capacity

What happened

Vistra (VST) rose 10.8% on October 6, 2026, after the U.S. Department of Energy offered a conditional $4.2 billion loan to support expansion of the company’s nuclear capabilities, according to The Motley Fool and Zacks Investment Research. The stock closed at $160.50 after opening 4.5% above the previous close. Trading volume was 3.3 times its 20-day average, and the move far outpaced the market: the S&P 500 rose 0.6% and the utilities sector median rose 1.1% on the day.

How big was the move

The gain was 3.7 times a typical daily move for this stock and beat its sector median by 9.7 percentage points on the day. Over the last five sessions the stock rose 14.0% versus the S&P 500’s rise of 1.9% across the same period. The stock’s market sensitivity is elevated with a beta of 1.56, meaning it tends to move more than the market. In the past five years the stock had 6 sessions with a gain of at least 10.8%; twenty trading days later the median result was a gain of 1.1%, and 3 of 6 were higher.

Taken together, the price action looks largely company-specific: the move came after the DOE announcement and far exceeded both the broader market and the utilities sector on the day.

The technical picture

The stock traded 12.6% above its 20-day moving average and 12.2% above its 50-day moving average, while it was 3.7% above its 200-day moving average. The 50-day average is below the 200-day average, a sign of a weak longer-term trend. The Relative Strength Index (14 days) was 72, above 70, a level often called overbought. The stock remained 26.1% below the 52-week high, and its one-year performance fell 20.5%, leaving it 37.0 percentage points behind the S&P 500 over the same period. Volatility was 46% annualized over 60 days, higher than 63% of its own readings over five years.

Shorter-term momentum has been mixed: the stock rose 7.5% over one month and 3.7% over three months, but the longer trend and elevated volatility point to continued sensitivity around major news events.

Fundamentals and valuation

For the four quarters through June 30, 2026, revenue was $15.98 billion, a decline of 28.4% from a year earlier and a further slowing versus the prior quarter’s decline of 25.5%. Diluted earnings per share were $5.94, down 5.4% from a year earlier. Gross margin slid to 13.0% from 40.6% a year earlier and operating margin fell to 2.3% from 33.5%, while free-cash-flow margin was 8.6% and return on invested capital was 0.9%. The balance sheet shows net debt of 3.0 times EBITDA and share count over one year increased by 0.1%.

Valuation metrics show the stock at 27.0 times trailing earnings, which is higher than 57% of its own readings over the past five years; the five-year median is 25.7 times earnings. Price to forward earnings is 18.6 times expected earnings and free-cash-flow yield is 2.9%.

Those figures sketch a company with strained profitability and a hefty historical valuation, even as the DOE loan announcement has driven a near-term re-rating of the shares.

Earnings and analyst expectations

Vistra’s next report is scheduled for November 6, 2026. The last report, on August 7, 2026, showed earnings per share of $0.76 against $1.61 expected, 52.8% below estimates; the stock typically fell 1.6% over a two-day window after recent reports. The company has zero consecutive quarters beating estimates and the average surprise over the last four reports was 6.9% below estimates.

Analysts’ consensus rating is Buy. Of the 23 analysts covering the stock, 91% issued Buy ratings, and the consensus price target is $215.67, 34.4% above the closing price.
