Can Constellation Energy (CEG) Justify Its Valuation Following Data Center Power Deals?

Constellation Energy (CEG) has moved into the spotlight after filing a detailed protest with the Federal Energy Regulatory Commission that challenges PJM’s proposed Interim Resource Adequacy Service and Large Load Registry framework.

Recent trading in Constellation Energy reflects this push and pull between strong nuclear and data center demand tailwinds and fresh regulatory and acquisition headlines. The share price closed at US$262.8, with a 1-day share price return of 1.26%. However, the 7-day share price return declined 8.10% as investors digested the PJM protest, Calpine-related equity overhang and ongoing clean-energy expansion. The longer history shows that short term momentum has cooled, while the 3-year total shareholder return of 143.68% highlights how powerful the earlier run had been relative to this year’s reset. This includes a year-to-date share price return down 28.25% and a 1-year total shareholder return down 18.11%.

Constellation Energy now sits between powerful AI and nuclear tailwinds, and a sharp pullback that reset expectations. After this reset, does the current valuation still tilt the risk reward in buyers’ favor?

Most Popular Narrative: 24.9% Undervalued

Constellation Energy last closed at $262.8 against a narrative fair value of $350. This gap frames the debate around whether the recent pullback has simply reset expectations or opened up a wider margin between price and long term earnings power.

The market is underappreciating how scarce true 24/7 carbon-free baseload has become just as AI data centers and electrification drive the sharpest sustained rise in U.S. power demand in decades. Most investors still treat CEG as a utility with nuclear exposure. It is better understood as the owner of the largest, highest-quality fleet of scarce, dispatchable zero-carbon generation that hyperscalers cannot easily replicate or replace.

See why 16 investors see Constellation Energy as 25% undervalued.

Result: Fair Value of $350 (UNDERVALUED)

Still, if Constellation Energy runs into tougher nuclear regulatory outcomes or weaker long term contracting appetite from hyperscalers, this scarcity driven narrative could reset fast.

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

Constellation Energy looks cheap against the narrative fair value, yet the P/E ratio tells a harder story. At 26.9x earnings, the stock trades well above both the peer average of 19.7x and the US Electric Utilities industry at 20.1x, even though the fair ratio points closer to 31.8x.

One way to read that gap is as follows: the market already prices in a premium for Constellation Energy compared with its sector, but not the full upside implied by the fair ratio. The question for investors is whether that premium is enough compensation for earnings and balance sheet risks if sentiment sours again.
