Vistra Stock Looks Cheap: Can AI Power Demand Unlock VST’s Upside?
Vistra offers exposure to rising AI power demand at a modest valuation. Meta and AWS contracts support growth, but spending needs and Moss Landing risks complicate the outlook.
Mikirduit — Vistra Corp. (NYSE: VST) offers investors a potentially discounted way to invest in America’s growing appetite for electricity. Its power plants already generate substantial cash, while long-term agreements with Meta Platforms and Amazon promise greater visibility into future sales.
3 Key Takeaways
- Vistra’s first-half 2026 adjusted EBITDA rose 26%, while accounting effects from hedging obscured stronger underlying performance.
- Meta and AWS contracts cover roughly 3.8 GW of nuclear power, with deliveries ramping through 2034. Contract prices remain undisclosed.
- Mikirduit’s base-case valuation suggests roughly 15% upside, balanced against expansion costs, power-market volatility and continuing Moss Landing liabilities.
The question is how much of that opportunity will translate into higher earnings—and how much investors should pay before it does.
Vistra operates roughly 44 gigawatts of generating capacity across natural gas, nuclear, coal, solar and battery storage. Its retail business serves approximately 5 million customers.
For a company of that scale, growth depends on more than rising electricity demand. Additional generating capacity, stronger realized power prices and better operating margins all matter.
Falling Revenue Masks Stronger Operating Results
Vistra’s second-quarter 2026 results initially look underwhelming. Reported revenue fell 5.5% to approximately $4.02 billion, while net income attributable to Vistra declined 6.7% to $305 million.
Revenue from contracts with customers, however, rose 17.3% to $4.40 billion.
The distinction reflects Vistra’s accounting for hedging and other revenue items. Reported revenue includes those adjustments, including changes in the value of commodity derivatives, which can obscure the performance of the underlying electricity business.
For the first half of 2026, reported revenue increased 18% to approximately $9.66 billion. Ongoing operations adjusted earnings before interest, taxes, depreciation and amortization rose 26% to $3.26 billion.
Vistra also disclosed $7.13 billion of remaining performance obligations tied to fixed capacity payments. These payments compensate the company for making generating capacity available, rather than solely for the electricity it produces.
The recognition schedule includes approximately $966 million in the remainder of 2026, $1.71 billion in 2027, $733 million in 2028, $215 million in each of 2029 and 2030, and $3.29 billion in 2031 and beyond.
That provides a measure of revenue visibility, although it does not represent Vistra’s entire contracted electricity-sales backlog.
Three Ways Data Centers Could Drive Growth
The first—and most visible—opportunity comes from direct contracts with technology companies.
Vistra’s 20-year agreements with Meta Platforms (NASDAQ: META) cover 2,176 megawatts of existing nuclear capacity and another 433 MW of planned capacity increases.
Deliveries from the existing capacity are expected to begin in part in late 2026 and reach full delivery by the end of 2027. The additional capacity is expected to begin contributing in 2031, with full delivery by the end of 2034.
Separately, Vistra has a 20-year agreement with Amazon Web Services, part of Amazon.com Inc. (NASDAQ: AMZN), for 1,200 MW from its Comanche Peak nuclear plant. Deliveries are expected to begin in the fourth quarter of 2027 and reach full capacity by 2032. The agreement includes extension options.
The documents reviewed do not disclose the electricity prices under these contracts. To illustrate their potential scale, Mikirduit assumes:
- A 90% capacity factor across the combined 3,809 MW.
- An electricity price of $60 to $100 per megawatt-hour.
Those assumptions imply approximately 30 million MWh of annual generation and $1.8 billion to $3 billion in annual electricity sales once all contracted capacity is fully delivering.
On the stated schedule, 2035 would be the first full calendar year after the final capacity additions reach full delivery.
That estimate requires an important qualification: it is an illustration of gross electricity sales, not disclosed contract value or entirely incremental revenue. Much of the electricity would come from existing plants that already sell power.
The financial benefit therefore depends on contract pricing relative to previous sales, greater revenue certainty and the contribution from additional generating capacity.
The second opportunity comes from tighter electricity markets.
Data centers increase demand for both energy and dependable generating capacity. Vistra could benefit through stronger wholesale prices, more favorable plant utilization and capacity payments, even when it does not supply a data center directly.
The third opportunity comes through new investments.
Vistra has committed up to $1 billion to Helix, including an initial $500 million commitment. An additional $500 million is linked to commercial milestones, although Vistra can elect to invest it regardless of whether those milestones are met.
The investment could create opportunities for new power contracts. It also requires capital, and its future revenue contribution remains uncertain.

What Vistra’s Valuation Implies
At the September 24, 2026 reference price of $137.94, Mikirduit’s analysis considers four valuation approaches.
The first is a comparison with other electricity and energy-related companies.
Mikirduit’s screen places Vistra’s enterprise-value-to-adjusted-EBITDA multiple at approximately 9.6 times, the lowest in its selected group. That group includes GE Vernova (GEV), NextEra Energy (NEE), Southern Co. (SO), Constellation Energy (CEG), Duke Energy (DUK), American Electric Power (AEP), Dominion Energy (D), Entergy (ETR) and Xcel Energy (XEL).
The comparison is a starting point rather than a definitive ranking. The group spans equipment suppliers, regulated utilities and competitive generators, whose business models and risks differ substantially.
The second approach compares Vistra with its own history.
Against Mikirduit’s cited five-year average of 9.7 times EV/EBITDA, the current 9.6 times represents only a modest discount. That comparison alone offers limited evidence of substantial undervaluation.
The third approach is discounted cash flow.
Mikirduit’s DCF estimate places fair value at $162.28 a share, implying approximately 17.6% upside from the reference price. That estimate depends on the model’s cash-flow, discount-rate and terminal-value assumptions.
The fourth approach uses EBITDA scenarios informed by management’s outlook.
Vistra’s 2026 adjusted EBITDA guidance is $6.8 billion to $7.6 billion. Management has also identified a potential 2027 EBITDA range of $7.4 billion to $7.8 billion, although that is an opportunity estimate rather than formal guidance.
| Scenario | EBITDA Assumption | EV/EBITDA Assumption | Estimated Share Value | Change From $137.94 |
|---|---|---|---|---|
| Bear case | $6.8 billion | 8.5× | About $105 | −24% |
| Base case | $7.6 billion | 10× | About $159 | +15% |
| Bull case | $7.8 billion | 11× | About $188 | +36% |
These are analytical scenarios, not company price targets. They use the previously assessed capital structure and share count and do not incorporate the full pro forma effects of the pending Cogentrix acquisition.
The base case suggests meaningful, but not overwhelming, upside. A stronger outcome would require both earnings delivery and investors’ willingness to assign a higher valuation.
The Risks Behind the Discount
Vistra’s first challenge is protecting margins.
Higher electricity demand does not automatically produce higher profits. The company’s earnings depend on the spread between realized power prices and production costs.
Natural gas is a major part of its generating portfolio. Strong demand combined with favorable fuel costs can support gas-plant margins, but cheaper gas can also pull wholesale electricity prices lower. The relationship between fuel costs and power prices matters more than either variable alone.
The second challenge is the cost and availability of equipment and labor.
Vistra says supply-chain constraints and labor shortages have increased procurement times and maintenance costs. Its review of project economics has led to the deferral or abandonment of some planned spending on solar and battery projects.
Separately, the company recorded approximately $68 million of impairment charges in the second quarter of 2025 for development projects it no longer planned to complete.
The filing does not identify those projects or explicitly attribute the entire charge to equipment and labor constraints. It should not be confused with the losses associated with Moss Landing.
The third challenge is timing.
The Meta and AWS agreements offer long-term revenue visibility, but the full contracted capacity will take years to come online. Contributions should build progressively, while investment spending and execution risks arrive earlier.
The fourth challenge is the continuing fallout from the Moss Landing battery fire.
On January 16, 2025, a fire broke out at Vistra’s 300-MW battery storage facility in California. According to the Environmental Protection Agency, approximately 55% of the roughly 100,000 battery modules were damaged. Vistra subsequently wrote off approximately $400 million of the facility’s book value.
The site experienced another flare-up in February 2025. On September 18, 2026, fire again emerged in the previously damaged Moss 300 building while cleanup remained underway. Authorities reported that the incident had stabilized by September 19.
The latest incident does not automatically imply another asset write-off equal to the original loss. It does, however, reinforce the risk of additional cleanup costs, delays and legal expenses.
Lawsuits related to the original incident have already been filed. Further costs and uncertainty could weigh on cash flow and investor sentiment.
Vistra’s appeal rests on a substantial operating business with room to benefit from growing electricity demand. Its long-term technology contracts strengthen that case. At the current valuation, however, investors are still relying on management to turn those opportunities into higher cash flow per share while containing the costs of expansion and legacy liabilities.
The numbers are only the beginning.
