Constellation Energy Raises Outlook as Data Center Power Deals Fuel Stock Rally

Strong Earnings and Power Contracts Reassure Investors

Constellation Energy (CEG) shares jumped more than 10% on Monday, November 9, after the electricity producer reported better-than-expected third-quarter results and raised its full-year earnings outlook for the second time in 2026.

The rally followed a difficult week for power and AI infrastructure stocks, when concerns about potential data center restrictions following the U.S. midterm elections weighed on the sector. Constellation's results and expanding portfolio of long-term electricity agreements showed that major customers continue securing power despite regulatory uncertainty.

Key Points

• Earnings and guidance strengthen: Constellation reported adjusted third-quarter earnings of $5.06 per share and raised its 2026 adjusted earnings outlook to $12.50–$12.80 per share.
• Long-term electricity demand remains strong: The company has secured more than 8,500 megawatts of long-term agreements this year, including major arrangements with Google and Amazon.
• Regulatory concerns remain in focus: The results helped ease fears about data center restrictions following the midterm elections, although uncertainty surrounding future development and electricity costs persists.

Constellation's Earnings Beat Supports a Higher 2026 Outlook

Constellation Energy delivered a strong third quarter, with adjusted operating earnings rising to $5.06 per share from $3.04 a year earlier. Revenue increased approximately 45% to $9.55 billion, exceeding Wall Street expectations. The improvement was driven largely by the contribution from Calpine, acquired earlier this year, alongside favorable commercial performance and higher capacity prices in the PJM electricity market. These benefits were partially offset by lower nuclear production tax credit revenue and unfavorable interest-related factors.

Operational performance was also strong. Constellation's nuclear fleet achieved a 97.2% capacity factor during the quarter, representing the proportion of its potential electricity output that was actually generated. Performance averaged 99.2% during the summer months, reflecting consistently high output from the company's nuclear facilities.

Following the results, management raised its full-year adjusted operating earnings guidance to $12.50–$12.80 per share, compared with its previous forecast of $11.50–$12.50. The revised range exceeded analysts' expectations and marked the company's second guidance increase this year. The stronger outlook helped lift Constellation shares, with the stock trading near $274 during Monday's session after gaining more than 4% on Friday. The positive reaction extended to other electricity and infrastructure companies, including Vistra (VST), GE Vernova (GEV), Bloom Energy (BE) and Vertiv (VRT).

Why Are Constellation's Long-Term Power Agreements Important?

Beyond its quarterly performance, Constellation's expanding portfolio of electricity contracts was central to Monday's market reaction. The company secured approximately 4,560 megawatts of long-term agreements with three customers during the third quarter, bringing its total for the year to more than 8,500 megawatts. Major technology companies are increasingly seeking dependable electricity supplies for data centers and artificial intelligence infrastructure, and Constellation's nuclear and natural gas generation portfolio positions it to serve customers requiring substantial amounts of power over extended periods.

Among its recent agreements is a 20-year arrangement with Amazon (AMZN) covering 690 megawatts, expected to support more than $3 billion in investment at the Calvert Cliffs Clean Energy Center, including an expansion of generating capacity. Constellation also announced a 20-year power purchase agreement with Alphabet (GOOGL) subsidiary Google, supporting more than $4.3 billion in investments across nuclear facilities in Illinois, Pennsylvania and New Jersey. The agreement is expected to add approximately 890 megawatts of generation capacity, with the first upgrades beginning in 2028. A separate 15-year agreement with Google covers 2,700 megawatts of electricity in the PJM market. Constellation also signed its first 20-year agreement through its Peak+ offering, covering 270 megawatts from its existing nuclear fleet while addressing growing electricity demand and potential grid requirements.

These agreements extend the company's revenue visibility well beyond the current year. According to Evercore ISI analyst Nicholas Amicucci, long-term contracts now support approximately 45% of Constellation's expected clean baseload generation in 2032, referring to electricity production capable of providing a dependable supply over extended periods. Constellation continues to target annualized base earnings growth exceeding 20% from 2026 through 2029, with several agreements expected to begin contributing in 2028 and beyond. The company has also received a conditional federal loan commitment that could provide up to $5 billion in financing for nuclear capacity upgrades, subject to a final agreement.

Can Data Center Regulation Slow Constellation's Growth?

Despite Monday's strong earnings reaction, regulatory uncertainty remains an important issue for the electricity sector. Power and infrastructure stocks experienced substantial selling following the November 3 midterm elections, when Democratic victories raised concerns about tighter oversight of data center development. Texas has become a particular focus, with Governor-elect Gina Hinojosa indicating plans to restrict new data center permits until additional protections addressing electricity costs and grid reliability are established. Those proposals have raised questions about future infrastructure projects and electricity demand, contributing to Constellation's sharp decline during the preceding week.

Management pushed back against concerns that regulatory changes would fundamentally undermine its growth plans. CEO Joe Dominguez emphasized that Constellation's new agreements are designed to expand electricity supply without imposing additional costs on existing customers. The company's position reflects a broader debate over who should pay for infrastructure supporting large data centers. President Donald Trump has urged lawmakers to advance permitting legislation that would accelerate energy infrastructure development while requiring data centers to cover their own electricity needs. Although the legislation remains uncertain, the issue is already influencing discussions among utilities, regulators and technology companies.

Wall Street analysts remain divided over the implications. KeyBanc analyst Sophie Karp has highlighted policy uncertainty following the Texas election, warning of potential consequences for power producers. Morgan Stanley, meanwhile, argues that the recent sector selloff may have been excessive, with restrictions potentially delaying some projects rather than derailing the broader investment cycle. The firm favors Constellation's exposure to the Mid-Atlantic and PJM electricity markets, which it views as having a more stable regulatory backdrop than Texas, and maintains an Overweight rating with a $391 price target. Evercore ISI remains constructive as well, maintaining an Outperform rating and a $380 target. These assessments highlight the distinction between potential delays in future construction and the value of electricity contracts already secured.

What It Means for Investors

Constellation Energy's latest results highlight the difference between near-term political uncertainty and longer-term demand for reliable electricity. Its earnings growth, higher guidance and expanding contract portfolio provide evidence of continued commercial activity despite concerns about data center regulation. However, several major agreements involve capacity expansions and investments scheduled to begin contributing in 2028 or later, making regulatory decisions, construction schedules and electricity market conditions important factors in determining when that growth translates into earnings.

Valuation is another consideration. Before Monday's rebound, Constellation traded at approximately 21 times forward earnings, below its three-year average of 26 times but above levels seen in late 2023. That comparison reflects a market reassessing the company's growth potential alongside uncertainty surrounding future power demand. The central question is whether Constellation can continue converting large electricity agreements into dependable earnings while navigating changing regulatory requirements.

Conclusion

Constellation Energy's third-quarter results offered a counterpoint to recent concerns about AI-related electricity demand. Higher earnings guidance, expanding long-term contracts and continued investment in nuclear generation supported a sharp rebound in its shares, while agreements with Google, Amazon and other customers indicated that large electricity buyers remain active.

Although regulatory uncertainty and the timing of future capacity additions remain risks, the company's latest report provides greater visibility into its contracted growth opportunities without resolving the broader debate over data center development.
