What Happened?
Constellation Energy Corporation (CEG) stock slipped 1.6% last week as investors weighed a negative project update against a still-strong long-term power demand story. The biggest headline came on March 26, when a company executive said PJM had told Constellation that the restarted Crane Clean Energy Center, formerly Three Mile Island Unit 1, may not be able to reconnect to the grid until 2031. That is later than the company’s original 2027 target, and Reuters reported the stock fell about 3% on the news.
That mattered because the Crane restart is tied to a 20-year power purchase agreement with Microsoft. In plain language, Constellation wants to bring an idled nuclear plant back to serve large data-center demand, but grid interconnection timing now looks like a real constraint. Investors had been treating nuclear power as a scarce asset in the AI buildout, so a delay naturally pressured sentiment.
There was also a deal-related overhang in the background. On March 18, Constellation agreed to sell a 4.4-gigawatt PJM generation portfolio to LS Power for $5 billion as part of regulatory commitments tied to its Calpine acquisition. The sale helps clear the merger process, but it also reminds investors that integration and regulatory remedies can reshape the earnings mix.
The weekly move came even though the broader operating story has stayed solid. In its February results, Constellation said full-year 2025 adjusted operating earnings rose to $9.39 per share from $8.67.
CEO Joe Dominguez said the company entered 2026 “well positioned to meet the nation’s growing demand for reliable, clean electricity.” So last week looked more like a reset around project timing and execution risk than a reversal in underlying demand.

Is CEG Stock Undervalued?
Under valuation model assumptions realized through 12/31/28, the stock is modeled using:
- Revenue growth (CAGR): 9.7%
- Operating Margins: 16%
- Exit P/E Multiple: 24.7x
Based on these inputs, the model estimates a target price of $400.94, implying 34.3% total upside from the current share price and a 11.3% annualized return over the next 2.7 years.
The valuation case looks reasonable, but not effortless. An 11.3% annualized return is attractive enough to matter, yet it depends on Constellation holding elevated earnings power after a huge run in nuclear-related expectations. The stock already trades at about 40.4x LTM earnings and 24.6x LTM EV/gross profit, so the market is still assigning a premium to its clean power portfolio and data-center optionality.
That premium is tied to real business strength. Constellation generated $25.5 billion of revenue in 2025, produced $5.6 billion of EBITDA, and ended the year with LTM net debt of about $5.9 billion, or roughly 1.0x EBITDA. That balance-sheet position matters because it gives the company more room to invest in nuclear uprates, plant life extensions, and large customer contracts than a more leveraged utility might have.
The earnings quality story is also better than the GAAP decline might suggest. Full-year GAAP EPS fell to $7.40 from $11.89, but adjusted operating EPS increased to $9.39 from $8.67 because market conditions, higher Illinois ZEC revenues, and favorable outage performance helped offset weaker nuclear PTC portfolio results. For investors, that means the core fleet still performed well even as accounting and market mark-to-market items moved around.
So the key question is not whether Constellation owns valuable assets. It is whether nuclear demand, commercial execution, and the Calpine integration can support mid-to-high single-digit revenue growth and mid-teens margins over time. If those pieces hold, the valuation can work, but the stock is likely to stay sensitive to each new project update.
What’s Driving CEG Stock Going Forward?
The next near-term catalyst is management’s 2026 Business and Earnings Outlook call on March 31. Investors will be listening for fresh guidance, comments on Calpine integration, and any clarification on the Crane restart timeline after last week’s PJM headline. Because the stock has cooled from its highs, precise guidance matters more now.
Data-center power demand remains the biggest strategic driver. Constellation said its expanded fleet is serving accelerating demand driven by “electrification and the data economy,” and Dominguez highlighted long-term agreements with Microsoft, Meta, and CyrusOne. Those deals matter because they can turn power scarcity into contracted revenue, not just spot-market upside.
Nuclear execution is the second driver. The company said its nuclear fleet produced 45,459 GWh in the fourth quarter, while owned nuclear capacity factor excluding Salem and STP was 93.1% in the quarter and 94.7% for the full year. For a generator like Constellation, high uptime is critical because every additional day online supports both earnings and the credibility of future customer contracts.
Investors should also watch how Constellation balances growth and capital intensity. Free cash flow turned positive to about $1.3 billion in 2025 after several negative years, but nuclear restarts, decommissioning contributions, and integration work still require meaningful cash.
That is why future stock moves will likely depend on three things at once: contract wins, grid and regulatory execution, and evidence that growth projects are translating into durable cash generation.
