Other companies like Duke Energy Corporation (DUK - Free Report) and The Southern Company (SO - Free Report) have declined 5.7% and 6.7%, respectively, during the same period.
Duke Energy is also actively pursuing nuclear energy expansion as part of its long-term clean energy strategy, particularly in the Carolinas. Southern Company is another major U.S. electric utility serving the fast-growing Southeast, benefiting from rising electricity demand, regulated investments and a diversified generation portfolio.
Given the current gain in prices, should you consider adding Constellation Energy to your portfolio? Let’s examine the key factors and assess their investment prospects.
Key Factors Powering CEG Stock’s Performance
Constellation Energy is benefiting from rising clean-energy demand through the diversified generation portfolio, led by its extensive nuclear fleet. Its nuclear assets achieved a 93% capacity factor in the second quarter of 2026, underscoring strong reliability and zero-carbon generation capabilities.
The company is also securing long-term clean-energy agreements with major customers. Constellation Energy’s 15-year nuclear power agreement with Walmart will supply nearly 176 MW from the Dresden Clean Energy Center beginning in 2029 and 2030, supporting planned uprates, grid reliability and its long-term growth strategy.
Its capital plan remains focused on sustaining fleet reliability and funding projects that extend asset lives or add output. The company expects capital expenditures of about $5.7 billion in 2026 and $4.7 billion in 2027. Spending includes nuclear fuel inventory, uprates, license renewals and plant upgrades.
The Calpine acquisition, completed in January 2026, expanded Constellation Energy’s generation portfolio with natural gas, oil, geothermal, battery storage and solar assets. The deal also strengthened Constellation Energy’s competitive retail business, increasing its nationwide customer base to approximately 2.5 million accounts. Calpine’s contribution to second-quarter 2026 adjusted operating earnings demonstrates that the acquisition is already supporting Constellation Energy’s financial performance and is likely to contribute to its performance over the long term.
Risks to Constellation Energy’s Growth
Constellation Energy faces operational and regulatory risks tied to its large nuclear fleet, including unplanned outages, maintenance needs, fuel-supply constraints and potential policy changes. The company’s earnings are also influenced by weather conditions, fluctuations in wholesale power and fuel markets, and the growing adoption of customer-owned energy solutions that may temper long-term demand growth.
The Calpine acquisition has also increased debt levels and integration challenges. Moreover, uncertainty over nuclear tax credits and changing wholesale power market conditions could pressure profitability and overall financial performance.
Constellation Energy’s Earnings Estimates Moving North
The Zacks Consensus Estimate for Constellation Energy’s 2026 and 2027 earnings per share indicates a year-over-year increase of 28.01% and 7.96%, respectively.

CEG’s Debt Usage Is Lower Than Industry Peers
The total debt-to-capital of Constellation Energy is 43.32% compared with its industry’s 54.07%. The ratio indicates CEG is utilizing much lower debt compared with its peers to run operations. The declining interest rate will be beneficial for the company, as it will further reduce long-term interest expenses.

Wrapping Up
Constellation Energy is well-positioned to capitalize on rising clean-energy demand across its service territories. Supported by a robust generation portfolio, the company is equipped to meet growing energy needs in a reliable and efficient manner.
Constellation Energy’s rising estimates, strong ROE and lower debt usage make this Zacks Rank #3 (Hold) stock attractive. However, given CEG’s lower net margin compared with the industry, prospective investors may find it prudent to wait for a more attractive entry point.
