What Happened?
Constellation Energy (CEG), the nation’s largest private nuclear operator, closed its $16.4 billion acquisition of natural gas and geothermal company Calpine on January 7, reshaping its earnings identity ahead of a March 31 combined-company guidance call that Wall Street is watching closely, with shares at $303.32 against a median analyst price target of $405.
Constellation beat Q4 adjusted EPS at $2.3 versus the $2.23 LSEG consensus, while quarterly operating revenue rose to $6.07 billion from $5.38 billion a year earlier, though 30 non-refueling outage days versus just three in Q4 2024 pressured the quarter and drove Q4 GAAP EPS down to $1.38 from $2.71 a year earlier.
Constellation’s full-year 2025 nuclear capacity factor of 94.7%, roughly 4 percentage points above the industry average, an operational gap CEO Joe Dominguez has described as equivalent to an entire additional reactor’s worth of annual output, delivered FY2025 adjusted EPS of $9.39, beating guidance midpoint for the fourth consecutive year.
A confirmed March 18 agreement to sell 4.4 gigawatts of natural gas capacity in Delaware and Pennsylvania, including the Bethlehem, York 1, York 2, Hay Road, and Edge Moor facilities, to LS Power for $5 billion at $1,142 per kilowatt satisfies the largest required divestiture under the DOJ and FERC conditions attached to the Calpine deal.
Shane Smith, Executive Vice President and CFO, stated in the Q4 2025 earnings release that Constellation delivered full-year earnings exceeding the midpoint of guidance for the fourth consecutive year, a track record now backed by signed hyperscaler contracts with Microsoft, Meta, and CyrusOne covering hundreds of megawatts of dedicated nuclear and gas capacity.
Constellation’s forward runway combines nearly 1,000 megawatts of identified nuclear uprates at LaSalle, Limerick, and Calvert Cliffs, a $14 billion post-Calpine liquidity position, a 10% annual dividend growth commitment, and a $600 million buyback authorization, building a multi-year compounding case that a 26x forward P/E and 37.8% gap to the $405 median price target leave largely unpriced.
Wall Street’s Take on CEG Stock
The Calpine close, which added Calpine’s natural gas and geothermal fleet to Constellation’s nuclear base on January 7, directly expands the combined revenue base to $30.9 billion in FY2026, a 20.9% jump from $25.5 billion in FY2025, and the enlarged platform is what drives the EPS step-change the market has not yet fully priced.
TIKR estimates normalized EPS rising 28.7% to $12.09 in FY2026 and then compounding to $17.22 by FY2028, a trajectory anchored by the Calpine revenue consolidation, the nuclear PTC floor that protects downside earnings, and hyperscaler contracts with Microsoft (MSFT), Meta (META), and CyrusOne that lock in long-duration demand at premium pricing.
NextEra Energy (NEE), the largest U.S. utility by market cap carries a TIKR-estimated normalized EPS growth rate of 8.1% in FY2026, roughly one-third of CEG’s 28.7%, yet NEE trades at a meaningful premium multiple, making Constellation’s 26x forward P/E look structurally cheap against its actual earnings velocity.
Sixteen analysts carry buy or outperform ratings on CEG against just four holds and zero sells, with a mean price target of $399.78 and a high target of $481.00, reflecting broad conviction that the March 31 combined-company guidance call will formalize the Calpine earnings uplift the Street has been modeling in.
The $330.00 low target anchors the bear case to execution risk on the LS Power divestiture and potential regulatory friction, while the $481.00 high target reflects a scenario where the March 31 outlook call delivers guidance well above current consensus and hyperscaler contract momentum accelerates through mid-year.
What Does the Valuation Model Say?
The TIKR mid-case target of $665.36, implying a 119.4% total return and a 17.9% IRR over 4.8 years, rests on a 10.1% revenue CAGR through December 2030 and a net income margin expansion from 11.5% in FY2025 to 15.6% at mid-case, both of which are directly supported by Calpine consolidation revenue and the scaling hyperscaler PPA pipeline.
The market prices CEG at 26x forward earnings, less than half of where it traded three months ago at 38x, yet the underlying EPS is set to grow 28.7% in FY2026 alone, a compression that implies the multiple is punishing the stock for the wrong reasons.
The $5 billion LS Power divestiture of 4.4 gigawatts of PJM natural gas capacity, confirmed March 18 and priced at $1,142 per kilowatt, validates the asset quality of the Calpine portfolio and frees the balance sheet for the $600 million buyback and the TIKR model’s $665.36 target price.
Shane Smith, Executive Vice President and CFO, stated in the Q4 2025 earnings release that Constellation delivered full-year earnings exceeding the midpoint of guidance for the fourth consecutive year, a pattern of execution discipline that makes the March 31 combined-company outlook the single most important near-term signal for the thesis.
A sustained decline in PJM capacity prices, the regulated market that sets the revenue floor for Constellation’s uncontracted nuclear megawatts, would directly compress the EBITDA margin expansion from 15.9% in FY2025 to the modeled 28.7% in FY2026, breaking the TIKR target’s core assumption.
The March 31 combined-company guidance call is the number to watch: if FY2026 adjusted EPS guidance lands at or above $12.00, it confirms the TIKR model’s 28.7% EPS growth assumption is tracking and the 26x multiple is a buying opportunity, not a valuation floor.
