Vistra (VST) Gets $4.2 Billion DOE Nuclear Loan Offer

The US Department of Energy (DOE) has offered Vistra (VST) a loan of up to $4.2 billion to raise the output of three of its nuclear plants. DOE announced the offer on 5 October 2026. It is a conditional commitment, so no money has been lent yet.

Bloomberg first reported the plan on 2 October. Vistra shares rose 19.1% between the 2 October and 7 October 2026 closes. Other nuclear power stocks rose by similar amounts over the same days.

DOE's Office of Energy Dominance Financing, its lending arm, set out the offer in a press release dated 5 October 2026. It is a conditional loan commitment of up to $4.2 billion. Vistra must first meet technical, legal, environmental and financial conditions. Only then will DOE sign final loan documents and lend the money.

The loan would pay for uprates and modernisation at Beaver Valley in Pennsylvania, plus Davis-Besse and Perry in Ohio. An uprate is a rise in a reactor's licensed power. It needs approval from the Nuclear Regulatory Commission (NRC), the US nuclear regulator. The offer also includes an option to fund future uprates at Comanche Peak in Texas.

DOE says the work adds 433 MW of new nuclear capacity. DOE adds that it preserves nearly 4 gigawatts (GW) of baseload power. Baseload power is steady output that runs day and night. DOE says the work also supports running the plants for 20 years beyond their existing licences.

Vistra had not published its own release on the loan by the morning of 8 October 2026.

The 433 MW is already sold. In January 2026 Vistra agreed 20-year power sales to Meta Platforms, the owner of Facebook, covering the uprate output of the same three plants.

Bloomberg's report came during trading on 2 October 2026. Vistra closed that day at $140.02. The shares rose 3.5% on 5 October, to $144.89.

Vistra rose 10.8% on 6 October and 3.9% on 7 October, to $166.72. On 6 October Constellation Energy (CEG), a US nuclear plant owner, announced a power deal with Google, Reuters reported. Constellation shares rose 12.2% that day. Talen Energy (TLN), another nuclear plant owner, rose 12.4%.

From the 2 October close to the 7 October close, Constellation rose 16.4% and Talen 17.9%. Vistra rose 19.1%.

The dashed line marks 5 October, the day of the DOE offer. The bars under the price show the shares traded each day.

A moving average is the mean closing price over a set number of days. The 7 October close of $166.72 was 16.4% above the 50-day average of $143.20. It was 8.0% above the 200-day average of $154.33.

The Relative Strength Index (RSI) runs from 0 to 100. It compares gains with losses over the last 14 days. At the 7 October close Vistra's RSI stood at 75.6, above the 70 line that marks a stretched reading, one where gains have far outweighed losses.

The grey bars on the right show how many shares traded at each price, called the volume profile. The busiest band was $157 to $161. The 7 October close sat above it.

The next chart zooms in on the last three months. Each candle is one day. The thick body runs from the open to the close, while the thin line spans the high and low. Green means it closed above its open, red below.

On 5 October the shares opened at $144.04, ranged from $140.90 to $146.94 and closed at $144.89. The candle is green, as the close was above the open.

On these figures the loan is small next to Vistra's market value. The week's rise in market value was already larger than the loan.

A loan must be repaid with interest, so its value to shareholders depends on its terms. DOE has not published the loan's interest rate.

Vistra's market value was $56.0 billion at the 7 October close. The $4.2 billion equals 7.5% of it.

At 30 June 2026 Vistra had $19.6 billion of debt and $435 million of cash. That gives net debt of $19.2 billion. The loan equals 21.9% of it.

Vistra expects 2026 earnings before interest, tax, depreciation and amortisation (EBITDA) of $6.8 billion to $7.6 billion. It calls this Ongoing Operations Adjusted EBITDA. It is a non-GAAP measure, meaning it falls outside US accounting rules (GAAP).

Net debt is 2.7 times the $7.2 billion midpoint. The ratio shows how many years of these earnings the debt equals. The full loan would lift it to 3.2 times, all else equal.

The 433 MW equals 6.7% of Vistra's 6,448 MW of nuclear capacity. It equals 1.0% of Vistra's whole 43,641 MW fleet at the end of 2025. Vistra expects full output by the end of 2034.

Vistra's market value rose $9.0 billion over the same days. That is 2.1 times the loan itself.

DOE and Vistra must still sign final loan documents. Neither had given a date by the morning of 8 October 2026.

Vistra reports third-quarter 2026 results on 6 November 2026. The uprates also need NRC approval. Vistra plans to apply for Perry in the second half of 2029, Power magazine reported, with Beaver Valley and Davis-Besse to follow by 2032.

The DOE offer could help fund uprates whose power Meta has already agreed to buy. It is still a conditional loan. Vistra's 19.1% rise came alongside similar gains at Constellation and Talen.

Good places to start on the website:

The rise came in a week of nuclear power news. DOE offered Vistra a conditional loan of up to $4.2 billion on 5 October. Constellation Energy announced a power deal with Google on 6 October. Vistra rose 19.1% between the 2 October and 7 October closes. Two other nuclear plant owners, Constellation and Talen Energy, rose 16.4% and 17.9%.

No. DOE's 5 October 2026 announcement is a conditional commitment of up to $4.2 billion. DOE says Vistra must first meet technical, legal, environmental and financial conditions. Only then will DOE sign final documents and lend the money. Neither DOE nor Vistra had given a date for closing the loan by 8 October 2026.

Vistra owns six nuclear reactors at four plants, with 6,448 MW of net capacity at the end of 2025. Comanche Peak in Texas has two units, as does Beaver Valley in Pennsylvania. Perry and Davis-Besse in Ohio have one each. The DOE loan covers uprates at the three plants outside Texas, with an option for Comanche Peak.
