Constellation Energy Stock vs Vistra Stock: Which AI Power Play Has More Upside? - TIKR.com

📊 TIKR's financial model targets a 15% annualized IRR for Constellation Energy (CEG) compared to only 1% for Vistra (VST).

🏗️ CEG closed its acquisition of Calpine in early 2026, adding roughly 21,000 megawatts of capacity and nearly doubling quarterly revenue to $11.1 billion.

💰 Constellation Energy's FY2026 revenue is estimated at $38.8 billion with approximately $2 per share of earnings accretion from the Calpine deal.

📈 Wall Street analysts imply 40% upside for CEG and 47% for VST, but TIKR favors CEG even in its low-case scenarios.

🏭 CEG operates the largest US nuclear fleet and has submitted 5,000 megawatts of new capacity into PJM's interconnection queue.

🤝 Vistra signed long-term power purchase agreements with Meta for approximately 2,600 megawatts at its PJM nuclear sites.

📉 CEG stock trades at roughly 22x FY2026 estimated earnings after pulling back 36% from its 52-week high.

🚀 Management projects base earnings growth exceeding 20% for CEG through 2029 supported by inflation-linked nuclear tax credits.

💵 Vistra posted record Q1 EBITDA of $1.5 billion but faces limited forward upside after a five-year run from $18 to $154.

📉 TIKR's model values CEG at approximately $499 by 2030 (90% total upside) versus $160 for Vistra (5% total upside).

🔋 CEG expects $8.4 billion in free cash flow across 2026 and 2027, rising to $11.5-$13 billion by 2029.

📉 Vistra's consensus estimates exclude contributions from the pending Cogentrix acquisition and Meta nuclear PPAs.

Bullish Signals
  • CEG's Calpine acquisition adds roughly $2 per share of earnings accretion and nearly doubles quarterly revenue to $11.1 billion.
  • Management projects base earnings growth exceeding 20% through 2029 for CEG, supported by nuclear production tax credits that grow with inflation.
  • CEG operates the largest fleet of nuclear power plants in the US, providing clean, firm electricity ideal for AI data centers.
  • Constellation Energy has a commercial platform serving over 80% of the Fortune 100 and signed long-term data center offtakes.
  • Vistra posted record first quarter EBITDA of $1.5 billion with normalized EPS up 315% from the prior year quarter.
  • CEG stock trades at roughly 22x FY2026 estimated earnings, leaving significant distance between current price and model value.
  • Analyst consensus for CEG includes 19 analysts with a mean target of $368, implying 40.4% upside from the current close.
  • Vistra's generation segment delivered $1.43 billion of segment EBITDA in Q1 despite record mild weather pressuring retail margins.
  • CEG has submitted approximately 5,000 megawatts of new capacity into PJM's interconnection queue to capture incremental demand.
  • TIKR's model projects a 90% total return for CEG by the end of 2030 based on current operating income trajectories.
Risk Factors
  • Vistra's stock has already appreciated 746% over five years, leaving minimal forward room in the TIKR model.
  • Vistra's consensus estimates currently exclude any contribution from the pending Cogentrix acquisition or Meta nuclear PPAs.
  • Vistra trades at roughly 14x forward earnings on a lower absolute multiple with the AI power premium largely absorbed by the market.
  • The high target for Vistra ($320) versus the low target ($99) indicates a wider spread and higher uncertainty compared to CEG.
Full Analysis
This article compares Constellation Energy (CEG) and Vistra (VST) as investment plays in the AI data center power sector, arguing that CEG offers significantly more upside potential despite Wall Street's slightly higher implied targets for Vistra. The core thesis rests on TIKR's financial model, which projects a 15% annualized return for CEG versus just 1% for Vistra. This divergence is attributed to CEG's recent acquisition of Calpine, which nearly doubled its quarterly revenue and added substantial earnings accretion, while Vistra's stock price has already absorbed much of its historical growth from $18 to $154. Constellation Energy operates the largest US nuclear fleet and recently closed the Calpine deal in early 2026, adding 21,000 megawatts of natural gas and geothermal capacity. This integration pushed FY2026 revenue estimates to roughly $38.8 billion and added approximately $2 per share in earnings. Management projects base earnings growth exceeding 20% through 2029, supported by nuclear production tax credits, long-term data center contracts with major tech firms like Meta, and a commercial platform serving over 80% of the Fortune 100. Vistra combines a smaller nuclear fleet with a large natural gas portfolio and a retail electricity franchise across 40 states. While Vistra posted record Q1 EBITDA of $1.5 billion and signed significant power purchase agreements with Meta, the article notes its stock has already appreciated 746% over five years, leaving minimal forward room in the model. The piece concludes that while both companies are high-quality, CEG is undervalued relative to its scale and growth trajectory, whereas Vistra appears fairly valued after its massive run-up.
