• Total volume up 5%, with intermodal volume increasing by 7%

JACKSONVILLE, Fla. – October 21, 2026 – CSX Corp. (NASDAQ: CSX) today announced third quarter 2026 operating income of $1.57 billion and net earnings of $1.05 billion, or $0.57 per diluted share.⁵ In the third quarter of 2025, the company reported operating income of $1.09 billion and net earnings of $694 million, or $0.37 per diluted share.⁹ Excluding a non-cash goodwill impairment of $164 million in last year's results, third quarter 2025 adjusted operating income, net earnings, and EPS were $1.25 billion, $818 million, and $0.44, respectively.¹⁰ On a year-over-year basis and compared to adjusted results, operating income increased 25%, net earnings increased 29%, and EPS increased 30%.

Total volume of 1.69 million units for the quarter was 5% higher than third quarter 2025.⁷ Revenue totaled $4.02 billion for the quarter, increasing 12% year-over-year, due to increased fuel surcharge revenue together with higher volume and pricing across merchandise, intermodal, and coal.⁸

"CSX delivered strong earnings growth in the third quarter as disciplined execution helped us move more freight, for more customers, while maintaining our high standards for safety and service," said Steve Angel, president and chief executive officer. "The hard work of our railroaders has positioned us well as we enter the fourth quarter, and we look forward to making continued progress toward best-in-class performance in 2027."
