Constellation Energy Tops Q1 Forecasts, Keeps 2026 Guidance After Calpine Deal

Investor caution reflects questions about how fast new scale will translate into growth.

Overview

  • Constellation posted stronger Q1 results Monday, with adjusted EPS of $2.74 and revenue of $11.12 billion.
  • Shares gave back early gains after the company reaffirmed full‑year earnings guidance at $11 to $12 per share.
  • The January purchase of Calpine expanded the fleet, with April startups at the 105 MW Pastoria Solar project in California and the 460 MW Pin Oak Creek plant in Texas.
  • Constellation advanced a Texas data‑center plan through a net‑metering approval tied to a CyrusOne agreement that could scale to 760 MW.
  • Execution faces timing risks from a required 4.4 GW asset sale to LS Power plus reports of grid bottlenecks that could slow a Three Mile Island restart.
