Constellation Energy (CEG), through its Calpine unit, just signed a 380-megawatt power and infrastructure deal with data center operator CyrusOne in Texas, plus an exclusive option for another 380 MW.

That CyrusOne agreement lands while Constellation Energy’s shares trade at US$288.43, with a 7 day share price return of 10.33%, a 30 day share price return of 12.70% and a 3 year total shareholder return of about 2.5x, which together indicate long term strength but more recent fading momentum.

With CEG trading around US$288.43 after a sharp multi year run and a recent pullback, current metrics hint at some discount to analyst targets. This raises the question of whether there is still an entry point here, or if potential future growth is already reflected in the price.

Most Popular Narrative: 27.9% Undervalued

With Constellation Energy last closing at $288.43 against a narrative fair value of about $399.93, the current gap puts the data center power story into sharper focus.

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.

Curious how a utility gets priced like a growth story? This narrative leans on steadier revenue, firmer margins, and a richer future earnings multiple. The numbers behind that jump are worth a closer look.

Result: Fair Value of $399.93 (UNDERVALUED)

However, this growth story can wobble if nuclear regulatory costs climb faster than expected, or if data center power deals slip, shrink, or take longer to close.

Another View: Expensive On Earnings

That 27.9% gap to a $399.93 fair value sits beside a much tougher message from the market. Constellation Energy trades on a P/E of 38.2x, versus 22.4x for the US electric utilities industry and a fair ratio of 33.1x that our model suggests the market could move toward.

If earnings or sentiment cool, that richer P/E leaves less room for error than the narrative fair value implies. Which signal do you put more weight on today: the cash flow story, or what current buyers are willing to pay?
