Nuclear energy stocks by business role
A nuclear power contract can cover electricity from a plant that already runs or electricity from upgrades that take years to finish. When you compare nuclear energy stocks, find the business that earns the revenue and the event that lets it start.

Find the part of the nuclear supply chain you own
Start with the issuer’s segment disclosures. A generator earns money from supplying electricity or capacity. A fuel supplier sells material and services to the plant, and a reactor developer needs a project to turn a design into equipment or service revenue.

| Business role | Company examples | What to check |
|---|---|---|
| Operating generation | Vistra (VST), Constellation Energy (CEG) | Match the plant to its operating status, contract start date, and the amount of power covered. |
| Plant restart | Constellation Energy (CEG) | Constellation signed a 20-year agreement with Microsoft to support restarting the former Three Mile Island Unit 1. Track restart milestones and the first delivery separately from the signing date. |
| Uranium and fuel services | Cameco (CCJ) | Compare uranium deliveries and realized prices with fuel services and the separately reported results of its Westinghouse investment. |
| Reactor development | NuScale Power (SMR) | NuScale announced U.S. regulatory design approval for its 77 megawatt electric module in 2025. For a specific project, look for separate evidence of licensing, financing, and construction. |
Read the Vistra and Meta deal in two parts
In January 2026, Vistra announced agreements with Meta covering 2,176 megawatts from operating reactors and 433 megawatts of planned output increases at existing plants. Vistra said purchases would begin in late 2026 and additional capacity would come onto the grid through 2034. The company said the plants would continue supplying the grid.
Put the two quantities on separate lines in your notes. For the operating capacity, look for the contract start and the first period of delivery. For the output increases, record when the upgrades are due and look for disclosures that they entered service. This keeps a signed purchase separate from the timing of additional electricity on the grid.
Check the metric that could change your view
For the third quarter of 2026, Cameco reported 3.5 million pounds as its share of uranium production and 5.6 million pounds of uranium concentrate deliveries. Those are different measures because purchases and inventory also help cover deliveries. If your case depends on higher uranium prices, follow the realized prices and deliveries Cameco reports alongside the spot price.
Pick a nuclear energy stock and record the next observable event, the date you expect it, and the disclosure that would confirm it. Then search by ticker to find published research and compare the milestones other investors are watching.
