CSX combines an irreplicable Eastern rail duopoly and improving operating execution, but at 23.7x FY 2026 earnings its long-term upside depends on sustained intermodal conversion and disciplined capital returns.
Overview
CSX is a Class I freight railroad with approximately 19,500 route miles across 23 eastern U.S. states, the District of Columbia, Ontario, and Quebec. Its network connects industrial centers, more than 240 short lines, and over 70 ports, creating a difficult-to-replicate asset and an Eastern duopoly with Norfolk Southern. FY 2025 revenue was $14.09 billion, led by merchandise at $8.80 billion; intermodal, coal, and Quality Carriers trucking diversify the mix. After FY 2025 revenue declined 3.1%, Q2 2026 showed a sharp recovery: revenue increased 10.1% to $3.94 billion, diluted EPS rose 22.7% to $0.54, and operating margin expanded 240 basis points to 38.3%. Management raised FY 2026 guidance to mid-to-high-single-digit revenue growth, more than 350 basis points of operating-margin expansion, and over 80% FCF growth, with capex below $2.4 billion. **The investment case rests on an irreplicable network and improving productivity**, augmented by truck-to-rail conversion, Howard Street Tunnel, and the CPKC SMX corridor. At $47.43, the shares trade at 23.7x FY 2026 EPS, a premium to historical rail valuations. **The principal near-term catalysts are sustained margin gains and intermodal growth;** the five-year probability-weighted target is $53.81 before dividends.
