Constellation Energy (CEG) is back in focus after affirming a quarterly dividend of $0.4265 per share and announcing plans for a multi billion dollar buyback alongside guidance for double digit earnings growth through 2029.

The recent dividend affirmation and larger buyback plan come after a sharp run, with a 10.14% 1 month share price return and a very large 3 year total shareholder return. However, the year to date share price return of a 15.96% decline suggests some momentum may be cooling, even as the latest news keeps attention on growth and risk expectations.

If you are looking beyond Constellation Energy to other ways to position around the power demand story, it may be worth reviewing 91 nuclear energy infrastructure stocks.

With CEG trading at US$307.81, supported by a very large 3-year total return and currently indicating a 37% intrinsic discount plus around 20% upside to analyst targets, is there still a buying opportunity here, or is future growth already fully reflected in the price?

Most Popular Narrative: 17% Undervalued

With Constellation Energy’s fair value estimate at about $370.58 against a last close of $307.81, the prevailing narrative frames current pricing as a discount that depends heavily on how long dated nuclear cash flows and data center demand play out.

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 what earnings trajectory, margin lift, and end state profit multiple are baked into that fair value and long term contract story? The key inputs are more aggressive than you might expect for a regulated heavy nuclear operator, and the gap between optimistic and cautious analyst cases is wide enough to matter for anyone treating that discount as a clear signal.

Result: Fair Value of $370.58 (UNDERVALUED)

However, this depends on nuclear heavy assets remaining economically attractive and on big data center customers maintaining long term contracts rather than shifting preferences or locations.

Another View: Rich P/E Keeps The Debate Open

The earlier fair value work points to CEG trading at a discount, yet the current P/E of 48.1x sits well above the US Electric Utilities industry at 22x, the peer average at 22.7x, and even the fair ratio of 42.1x. That premium can signal confidence, but how comfortable are you paying up for it?
