The company's nuclear output reached 46,477 GWhs for the quarter, achieving a 96.8% capacity factor while total outage days plummeted to just 28 from 57 in Q3 2024, a operational improvement that underpinned the rise in adjusted net income to $952 million. GAAP results told a murkier story, with net income falling to $930 million from $1.2 billion, pressured by mark-to-market adjustments and a higher tax rate. Management responded to the strong execution by narrowing full-year 2025 guidance to $9.05–$9.45 per share, a tighter band that signals confidence heading into the anticipated Q4 close of the Calpine acquisition, a deal that has already prompted significant investor attention. The company also secured a $1 billion DOE loan guarantee to restart the Crane Clean Energy Center, adding further fuel to its long-term growth trajectory.
