Constellation Energy Corporation: Shares Consolidate After Earnings Beat

Constellation reported adjusted EPS of $1.91, beating the $1.84 consensus estimate, while GAAP EPS came in at $2.67. Revenue hit $6.10 billion, surpassing expectations, and the company reaffirmed full-year guidance of $8.90 to $9.60 per share.

The quarter was boosted by strong performance in its zero-carbon nuclear fleet, favorable clean energy credits, and rising demand from corporate buyers. Notably, Constellation secured a 20-year power agreement with Meta Platforms ((META Quick QuoteMETA - Free Report) ), reinforcing its status as a top utility provider to large tech companies and AI-intensive infrastructure.

Vistra: Profit Dips, But Stock Price Momentum Picks Up

Vistra’s adjusted EBITDA came in at $1.35 billion, slightly below last year’s $1.41 billion, while revenue rose about 10% year-over-year to $4.25 billion, though it came in light versus consensus. GAAP net income declined due to higher interest and operating costs, but the company reaffirmed full-year guidance and raised its 2026 EBITDA outlook above $6.8 billion.

A notable development this quarter was Vistra’s announcement that it executed a definitive agreement to acquire seven natural gas facilities totaling ~2,600 MW of capacity from Lotus Infrastructure Partners. This acquisition will further diversify Vistra’s natural gas fleet geographically and play a critical role in meeting the rising electricity demand from AI data centers and hyperscale infrastructure.

In addition to its nuclear footprint, Vistra’s growing natural gas portfolio positions it as a reliable, dispatchable power provider in a market that increasingly needs stability to support 24/7 AI workloads.

Despite the bottom-line dip, shares of Vistra are up nearly 4% on the day, as investors looked past near-term pressures and focused on its longer-term growth trajectory.
