Constellation Energy (Nasdaq: CEG) and NextEra Energy (NYSE: NEE) both missed Q3 2025 revenue expectations, but the stories reveal fundamentally different business models competing for the AI-driven energy boom.
Constellation posted $6.57 billion in revenue and $3.04 per share in adjusted earnings, both below Wall Street targets.

The company secured a $1 billion government loan to restart the Three Mile Island reactor, backed by a Microsoft power purchase agreement.
NextEra delivered $7.97 billion in revenue but beat on earnings at $1.13 per share versus the $1.05 estimate. The company added 3 gigawatts to its renewables backlog and announced a 25-year nuclear supply deal with Google to power Iowa data centers. Florida Power & Light contributed $1.46 billion in net income, providing the stable regulated base that funds NextEra Energy Resources’ renewable expansion. Management maintained 2025 earnings guidance of $3.45 to $3.70 per share and projected roughly 10% annual dividend growth through 2026.
