CSX Corporation's fourth-quarter 2025 results fell short of expectations, with earnings per share at 39 cents, below the anticipated 42 cents, and total revenues of $3.51 billion missing the $3.55 billion target. Declines in merchandise and coal revenues contributed to a year-over-year drop in operating income to $1.11 billion, while long-term debt increased to $18.2 billion. Despite a 7% rise in intermodal revenues, the company's financial outlook remains cautious, predicting low single-digit revenue growth amid broader market volatility and geopolitical uncertainties.
