Talen Energy is trading 4.27% up at $343.94 after investors reassessed its August 5 earnings release and higher outlook.

  • Management raised 2026 Adjusted EBITDA guidance to $2,025–$2,225 million and free-cash-flow guidance to $1,200–$1,350 million.
  • The higher outlook is supported by Cornerstone integration and stronger power-market fundamentals.
  • The catalyst outweighed concerns about the $2.00-per-share GAAP loss; shares had recovered 2.2% after-hours following the initial earnings reaction.
