Constellation Energy (CEG) is back in focus after securing long-term agreements to supply emissions-free nuclear power to Walmart and Meta, highlighting how large corporates are sourcing clean energy at scale.

Despite the long-term nuclear supply deals and recent index inclusions, Constellation Energy’s share price has come under pressure, with the stock down 35.43% on a year to date share price return and 22.47% on a 1 year total shareholder return. However, the 3 year total shareholder return of 161.96% still points to strong longer term momentum.

So, with Constellation Energy trading well below recent highs despite long-dated nuclear contracts with Walmart and Meta, as well as a wide gap to analyst price targets, is this a mispriced clean power leader or is the market already discounting future growth?

Most Popular Narrative: 34.3% Undervalued

Constellation Energy’s most followed narrative pegs fair value at $360.24 versus the latest close at $236.50, framing a sizable gap that hinges on long dated nuclear and AI power demand assumptions.

Strategic investments and progress in nuclear plant restarts (Crane Clean Energy Center), upgrades (900MW in engineering), and selective M&A (Calpine acquisition) provide visible avenues for substantial capacity additions and operational synergies, enhancing EBITDA and free cash flow over the medium to long term.

Want to see what turns those nuclear restarts and AI power deals into a much higher fair value? The narrative leans on faster revenue expansion, higher margins, and a richer future earnings multiple than many utilities typically command.

Result: Fair Value of $360.24 (UNDERVALUED)

However, Constellation Energy’s reliance on large nuclear assets and long duration data center contracts could backfire if regulatory costs rise or hyperscaler demand shifts.

Another View: What Constellation Energy’s P/E Is Telling You

The earlier narrative leans heavily on fair value models that suggest Constellation Energy is trading well below intrinsic worth. Yet on a simple P/E basis, the stock looks slightly expensive versus the US Electric Utilities industry at 22.3x vs 22x. It is still below a fair ratio of 29.8x that the market could move toward. That mix of mild premium today and potential headroom later raises a practical question for you: is this more margin of safety or valuation risk if expectations change?
