What Happened?
Constellation Energy (CEG) completed a $16.4 billion acquisition of Calpine on January 7, transforming from a pure nuclear operator into a diversified power provider at $322.85 per share.
On February 24, CEG reported Q4 adjusted EPS of $2.30, beating the $2.23 consensus estimate, while quarterly revenue hit $6.07 billion against a $5.49 billion estimate, a 10.7% surprise.
The company also secured a 380 MW data center agreement with CyrusOne at Calpine’s Freestone Energy Center in Texas, with an exclusive option for an additional 380 MW Phase 2, directly extending Calpine’s commercial value within weeks of closing.
Raymond James raised its price target to $406 while Citigroup cut to $348 and Mizuho cut to $330 on February 25, reflecting genuine disagreement about how quickly Calpine integration costs normalize against surging power demand.
CEO Joe Dominguez stated on the Q4 earnings call that “we’re pairing the grid’s most reliable power with flexible resources to meet accelerating demand driven by electrification and the data economy,” tying directly to the NRC-approved license extensions for Clinton station through 2047 and Dresden reactors through 2051.
With 2026 consensus EPS of $11.65 implying 24.1% growth, a $1 billion DOE loan guarantee backing the Crane Clean Energy Center restart, and a March 31 guidance call ahead, Constellation now controls the most strategically irreplaceable power infrastructure in the AI buildout era.
Wall Street’s Take on CEG Stock
The Calpine acquisition fundamentally changes CEG’s earnings identity, adding natural gas and geothermal capacity that pushes 2026 consensus revenue to $36.6 billion, a 43.3% jump from 2025’s $25.5 billion.
EBITDA margins are forecast to expand from 15.9% in 2025 to 21.4% in 2026, while normalized EPS grows from $9.39 to $11.37, a 21.1% increase grounded in contracted power demand from Microsoft, Meta, and CyrusOne.
18 analysts currently cover CEG with 10 Buys, 4 Outperforms, and 5 Holds against zero Sells, with a mean price target of $393.93 representing 22.0% upside from the current $322.85 close.
The high target of $481.00 reflects full execution on Calpine integration and accelerating data center power contracts, while the low target of $277.00 captures the risk of rising operating expenses, which already jumped 22.3% in Q4 2025.
What Does the Valuation Model Say?
A mid-case valuation model projects a $547.87 target price by December 2030, implying 69.7% total return from current levels. The model’s 11.6% annualized IRR suggests the market is not yet pricing in Calpine’s full earnings contribution.
The market appears to be discounting the compounding effect of CEG’s nuclear license extensions, which now extend Clinton through 2047 and Dresden reactors through 2049 and 2051.
The current P/E of 26x sits well below the three-months-ago level of 38x, despite a materially stronger forward earnings profile driven by the Calpine close and new data center agreements.
Management’s decision to raise the dividend 10% in 2026 while simultaneously guiding for a March 31 outlook call signals internal confidence that Calpine integration is tracking ahead of initial expectations.
The single biggest risk is operating expense inflation, with total Q4 2025 operating costs already rising 22.3% YoY to $5.48 billion, which could compress the forecasted 21.4% EBITDA margin.
The March 31 guidance call represents the clearest moment of truth for this thesis, as management will provide the first formal 2026 outlook incorporating a full quarter of Calpine ownership.
CEG is a structural buy driven by irreplaceable nuclear and now gas capacity in an AI power supercycle; monitor 2026 EBITDA margin execution against the 21.4% consensus target.
