Vistra

An American power producer: it runs gas, coal and nuclear plants, sells the electricity to 5 million homes and businesses, and uses each side to hedge the other.

The scores
The profile · 1-4
Growth3/4 ↑

Ongoing Operations Adjusted EBITDA is up over 30% YoY, but a material part is Energy Harbor/Lotus/Cogentrix M&A and hedge/price timing, not pure organic volume growth.

Business quality3/4 →

Irreplaceable licensed nuclear/coal plus an integrated retail hedge command real premiums, but untested by the emerging behind-the-meter substitution wave.

Financial position3/4 →

Investment-grade at two of three agencies with $6.3B of liquidity, but net debt rose about $3B in six months as acquisitions and buybacks ran together.

Execution record3/4 →

Guidance held through an ERCOT pullback and the buyback target was hit early, but the post-2021 restructured entity's clean record is still short.

Per share capture4/4 →

171 million shares retired against one small Cogentrix-related issuance - buybacks dominate the share-count trend by a wide margin.

Potential3/4 ↑

A large upside on observable steps - Batch Zero, Cogentrix, uprates - with one piece, the Meta PPA, already committed and in progress.

Risk profile3/4 →

A real regulatory dependency (Batch Zero, PJM tariff filings) and hedge-driven earnings volatility, but diversified across ERCOT/PJM/other ISOs and survivable if either resolves unfavorably.

Valuation3/4 →

EV/TTM Adjusted EBITDA near 10.0x sits below VST's own five-year median and only modestly above the peer GAAP-basis reading, once distortion is accounted for.

Evidence quality3/4 →

Central claims are mostly primary filings and transcript, cross-checked externally, but the cohort is thin and the TTM EBITDA figure is hand-computed, not filed.

The Verdict

We rate Vistra attractive. It runs gas, coal and nuclear plants that nobody can build again soon, and sells their power both wholesale and to its own retail customers, a solid business. Its reported profit swings because hedging contracts are revalued every quarter, but the cash business underneath grew over 30% last quarter. On that underlying profit the shares cost less than their own five-year norm, so the price is fair, needing only the forecast, with the AI demand close to free. The view hinges on management holding its 2027 profit aim as Texas power prices soften.

The long caseAI data centres, factories and a growing population are raising power demand in Texas and the eastern grid faster than in decades, and Vistra's existing plants sell into it.

Vistra maintained its 2027 Adjusted EBITDA midpoint opportunity of $7.4-7.8B despite ERCOT forward curves falling versus the October 2025 basis, citing PJM strength, hedging and the nuclear PTC as offsets; the range excludes Cogentrix and Meta PPA contributions.
against this

ERCOT day-ahead prices have run near half of the prior year's level for parts of 2026 per management's own commentary, and the 12-15 GW of realistic new ERCOT load Vistra is banking on (C29) is itself a management estimate rather than a filed figure.

derivedC09 and C10; the 11.51x prior-period median is the vendor market-tier figure (S16).
against this

The comparison leans on a vendor-reported five-year prior-period median (11.51x) that the pack itself does not fully audit the way it audits current-period figures, and on a hand-computed TTM Adjusted EBITDA (C09) rather than a single disclosed number.

The vendor-reported cohort EV/EBITDA multiple for VST of 21.1x is a GAAP figure and is inflated by unrealized hedge mark-to-market losses embedded in the trailing GAAP EBITDA base it is struck on.
derivedC06 and C07 show GAAP operating results carrying large unrealized hedge marks that Ongoing Operations Adjusted EBITDA excludes; the vendor cohort figure (S16) is computed on GAAP, not Adjusted, EBITDA.
against this

The vendor's separate top-level market-tier EV/EBITDA of 10.07x (S16) is close to the hand-computed Adjusted figure (C11), so not every vendor EBITDA field is equally distorted - the cohort-specific 21.1x figure appears to draw on a different, more GAAP-exposed quarter mix than the smoothed top-level ratio.

The company

Vistra's fleet is 62% gas, 20% coal, 15% nuclear and 3% solar and batteries, selling into six American wholesale power markets, mainly Texas's grid, ERCOT, and PJM in the mid-Atlantic and Midwest.

It also sells electricity and gas directly to about 5 million homes and businesses in 18 states and Washington, DC. A buyer who does not use Vistra buys from a rival generator on the same grid, or builds its own plant.

How it makes money

It earns the gap between what it costs to run its plants and what power sells for. Owning both the plants and the customers lets it lock in prices years ahead: when wholesale prices fall, retail margins cushion the blow. The contracts that do that are revalued every quarter, which is why reported profit jumps around while cash does not.

Who runs it

Jim Burke has run Vistra since 2022, after years as its finance and operations chief; Kris Moldovan, a company veteran, has run the money since the same year. On their watch Vistra bought more power plants, signed long nuclear contracts with big tech buyers and beat its own profit forecast. Insiders own under 1% of the company. Bonuses ride on adjusted profit and cash flow; long-term shares on cash flow per share and the stock against the market.

Why it wins, and who could beat it

Why customers come back

Its six nuclear reactors, 6,448 MW licensed to run into the 2030s and beyond, cannot be copied: no large reactor is under construction anywhere in the United States, and only two were finished in the past decade.

That scarcity is why a technology company wanting steady, carbon-free power for decades came to Vistra's existing plants, at a price the finance chief called above market, instead of waiting for someone to build new ones.

The threat

Data-centre owners are starting to build their own power. About 2 GW of off-grid generation was running by mid-2026, most of it gas turbines at xAI's sites, and Microsoft and Oracle are pursuing on-site power too. Every data centre powered that way is demand that never reaches Vistra's grid.

The evidence under this - 1 claim
C35factmedium confidence
Behind-the-meter, off-grid generation for data centers is scaling: about 2 GW was online by mid-2026, the vast majority of it xAI's Colossus gas-turbine sites, with other hyperscalers including Microsoft and Oracle (via a large Bloom Energy contract) separately pursuing on-site power for new capacity.
against this

Behind-the-meter capacity (about 3 GW by year-end 2026) remains a small fraction of the 12-15 GW of realistic new ERCOT load alone (C29), and cannot serve Vistra's 5-million-customer retail book or offer investment-grade counterparty risk transfer the way a PPA does (machine.threat.not_substituted).

How big it could get

How big this could get

Demand is rising after decades of flat growth. Texas's grid peaked at 83.7 GW in 2025 and above 91 GW in July 2026, and its planners point to about 152 GW by 2030.

The queue of requests to connect large new users there is reported near 410 GW, mostly data centres. Vistra's own chief executive thinks only 12 GW to 15 GW of that is realistic by 2030.

This 12-15 GW figure is Vistra's own filtering of the queue and is not independently verifiable; ERCOT and the Public Utility Commission of Texas's own Batch Zero audit (C32) exists precisely because nobody outside the generators has published a verified conversion rate from queue to real load (see machine.prize.composed_route).

What growth costs

Running Vistra gets no cheaper as it grows: office and selling costs rise in step with sales. Growth costs capital instead, buying plants and spending more each year upgrading them, so whether growing makes it more profitable depends on what those plants earn, which the reported figures, swung by hedging gains and losses, do not yet show.

  • The 2025 pay plan's total-cost metric missed its threshold, on growth projects, the Martin Lake 1 repair and integration costs (S20), so costs outside SG&A did rise faster than planned.

Operating profit
per dollar of sales

The June 2026 quarter looked like a miss: earnings per share of $0.76 against the $1.61 analysts expected, and revenue well short. It was not an operating miss.

A $472M paper loss on contracts protecting future prices went through the accounts. Underlying profit, the company's own measure without those swings, rose to $1,767M from $1,349M, over 30%. Management kept its 2026 forecast of $6.8B to $7.6B and its $7.4B to $7.8B aim for 2027, even as Texas power prices for future delivery fell.

What it did to the thesisIt supported the Attractive case: the earnings miss came from paper losses on hedges, while the company's own measure of underlying profit grew strongly and both forecasts held. What it left open is whether those forecasts survive weaker Texas power prices.

The price, and where we disagree

In short. Fair. Cheap on the profit the business actually makes, as long as the forecast holds; the AI demand comes close to free.

rivals' middle 14.1

Most coverage calls Vistra an AI-power play, and the standard price-to-earnings figure makes it look expensive. That figure is struck on the distorted reported profit. On the underlying profit the shares are cheaper than their own history.

The next test is the November 5 results: whether management holds its 2027 aim with Texas power prices softer.

The vendor-reported cohort EV/EBITDA multiple for VST of 21.1x is a GAAP figure and is inflated by unrealized hedge mark-to-market losses embedded in the trailing GAAP EBITDA base it is struck on.
derivedC06 and C07 show GAAP operating results carrying large unrealized hedge marks that Ongoing Operations Adjusted EBITDA excludes; the vendor cohort figure (S16) is computed on GAAP, not Adjusted, EBITDA.
against this

The vendor's separate top-level market-tier EV/EBITDA of 10.07x (S16) is close to the hand-computed Adjusted figure (C11), so not every vendor EBITDA field is equally distorted - the cohort-specific 21.1x figure appears to draw on a different, more GAAP-exposed quarter mix than the smoothed top-level ratio.

Vistra maintained its 2027 Adjusted EBITDA midpoint opportunity of $7.4-7.8B despite ERCOT forward curves falling versus the October 2025 basis, citing PJM strength, hedging and the nuclear PTC as offsets; the range excludes Cogentrix and Meta PPA contributions.
against this

ERCOT day-ahead prices have run near half of the prior year's level for parts of 2026 per management's own commentary, and the 12-15 GW of realistic new ERCOT load Vistra is banking on (C29) is itself a management estimate rather than a filed figure.

How we read the multiple

Counting its debt, the whole company costs about $66B, roughly 10 times last year's underlying profit before interest, tax and depreciation of about $6.6B, and about 9.2 times this year's forecast.

On reported profit, which paper losses on hedges pull down, it is about 21 times. So the price mainly asks that the forecast arrives. It pays little for signed data-centre demand beyond Meta, which is where the upside sits.

Against its own history. Below its own normal on underlying profit. The reported figure makes it look dear, but that comes from paper losses on hedges, not the business.

Enterprise value is approximately $65,955M: market cap $45,928M plus net debt of approximately $20,027M (long-term debt $19,595M, AR financing $300M, forward repurchase obligation $613M, less cash $435M and restricted cash $46M).
derived10-Q balance sheet (S02) and market-tier market capitalisation (S16).
against this

Net debt is a snapshot at 2026-06-30 and has already risen roughly $3B in six months (C16); using a post-Cogentrix-close balance sheet instead would show meaningfully more leverage against the same EBITDA base, making the multiple look more expensive than this snapshot does.

TTM Ongoing Operations Adjusted EBITDA through Q2 2026 is approximately $6,584M, computed as FY2025 ongoing-ops EBITDA ($5,912M) minus H1 2025 ($2,589M) plus H1 2026 ($3,261M).

against this

This is a hand-computed TTM figure, not a single filed number - it depends on H1 2025/H1 2026 Ongoing Operations figures being genuinely comparable across two different guidance vintages and any quarterly restatement between them would move it without a corresponding filing to flag it.

The middle of the other 2 is 14.1. Vistra Corp. is dearest of 3.

Rivals' figures come from a data provider, so read the spread of the group rather than any single pair.

The rivals' figures are struck on reported profit, which the hedges distort, so the comparison proves little either way and cannot move our view.

Where we disagree with the market

The market believes

An AI-power story, with a high price-to-earnings figure showing the market has already paid up for it.

We believe

The reported swings are mostly hedge accounting. On what the business actually earns, the market has not paid for the AI story at all.

The gap sits in a reconciliation table few people read, and even the data vendor's comparison with rivals uses the distorted figure.

The case against us: most AI demand is unsigned, Texas power prices for future delivery have softened, and data centres can build their own plants. A cut to the 2027 aim, rather than softer words, would prove us wrong.

What could go wrong, and how we would know

The risks

  • Demand that routes around it. Data-centre owners building their own gas turbines or fuel cells never need to buy from Vistra's grid.
  • Softer Texas prices. Battery buildout and a market redesign have lowered Texas power prices, and forecasts for 2026 demand growth were cut.
  • Debt and buybacks together. Borrowing rose $2.6B in six months while buybacks and a $2.3B acquisition continue.
  • A paused connection queue. A Texas audit has paused reviews of large new users, and it has already run longer than management expected.
