CEG Constellation Energy
Elite nuclear franchise, but 18x book prices peak AI-power returns as permanent.
The story
Constellation owns the largest US nuclear fleet, now joined with Calpine's gas fleet. It is a merchant and contracted generator, not a rate-base utility, so its returns follow power prices and capacity auctions rather than an allowed ROE. Trailing ROE of about 24% comes from peak capacity prices and scarcity pricing driven by AI demand. The nuclear PTC floor and 20-year hyperscaler PPAs (Microsoft, Meta) lock in part of the upside, but earnings in the 2021-22 range were near zero. Price is about 18x book, which assumes peak returns last indefinitely.
No facts changed since August. The price is down about 5% and the news flow (EFOF/fleet performance, sector hype) is noise, so I keep the drivers. A 16% normalized ROE credits the PPAs and the PTC floor but mean-reverts from the 24% peak. Beta of 0.8 sits above the 0.55 regulated anchor because CEG carries merchant commodity exposure, and 3.5% terminal growth stays below the 5.11% risk-free rate.

Key risks
- PJM capacity price cap/reform and power-price mean reversion compress merchant margins
- Calpine integration, gas-fleet commodity exposure and added leverage
- FERC/state pushback on behind-the-meter co-location deals; nuclear outage or regulatory event
Catalysts
- Additional long-dated hyperscaler PPAs at premium prices that lift normalized ROE
- Calpine synergies and buybacks, plus uprates/restarts (Crane) that grow contracted book
