Talen Energy's stock plummeted 6.67% during intraday trading on Friday, following the release of disappointing financial results and guidance.

The power producer reported a net loss attributable to stockholders of $363 million for the fourth quarter, a significant reversal from a profit of $82 million in the same period a year earlier. Furthermore, the company forecast its 2026 adjusted EBITDA to be in the range of $1.75 billion to $2.05 billion, which fell below analysts' estimates of $2.07 billion.

These weaker-than-expected financial metrics, highlighting both a recent quarterly loss and a cautious profit outlook for the coming year, were the primary drivers behind the stock's sharp decline in the session.
