Constellation Energy (NasdaqGS:CEG) has closed its acquisition of Calpine, expanding its US power generation portfolio.
The company has agreed long term renewable power deals with Microsoft and Meta to supply energy for AI focused data centers.
Regulators have extended licenses for several Constellation nuclear plants, while recent government decisions have affected certain tech related nuclear power agreements.
Constellation Energy now sits at the center of several big themes for investors, from AI driven power demand to the role of nuclear and renewables in the US grid. The stock trades at $280.68, with a 3 year return that is very large, while the 30 day return shows a 20.5% decline and the year to date move stands at a 23.4% decline.

The Calpine acquisition and fresh agreements with Microsoft and Meta could reshape Constellation’s revenue mix and exposure to long term contracts, while nuclear license extensions may support the company’s clean energy profile. At the same time, shifts in government decisions around tech related nuclear deals highlight the role of policy risk for Constellation’s future project pipeline.

Why Constellation Energy could be great value
For investors, the Calpine deal and 20 year power purchase agreements with Microsoft and Meta tighten the link between Constellation Energy and long-duration AI data center demand. The combination of a larger gas and geothermal fleet with the largest US nuclear fleet gives Constellation a mix of carbon free and dispatchable capacity that can appeal to hyperscalers that need 24/7 power, which sets it apart from peers like NextEra Energy and Duke Energy that are more tilted to regulated utilities and renewables.
The new contracts and plant license extensions line up closely with existing bullish narratives that focus on long term, higher margin agreements for carbon free power and capacity additions from restarts and uprates. At the same time, the regulatory pushback on a separate Big Tech nuclear deal and the focus on Calpine integration tie into the more cautious views that highlight execution risk, concentration in a few large customers and the importance of policy support for nuclear-heavy portfolios.
