CSX Corporation (CSX) Q2 FY2026: Record Revenue $3.94B, Net Income +21%, FCF 3.6x on Base Effects

CSX Corporation, which operates roughly 20,000 miles of rail network across 26 states east of the Mississippi River and ranks as the second-largest eastern freight railroad in the United States, reported Q2 2026 revenue of $3.94 billion, up 10.1% year-over-year. In its July 22 earnings release, the company called this a "quarterly revenue record." Diluted earnings per share came in at $0.54, up 23% — outpacing net income growth of 20.9% as the share count declined through buybacks.

The quality of that growth, however, is more nuanced than the headline suggests. The company's 10-Q filing identifies fuel surcharge revenue — not intermodal — as the primary driver of the 10% revenue increase. Intermodal revenue did surge 26.3%, but volume growth was only +9% (company-wide volume: +6%), with the remainder largely attributable to fuel pass-through. For the same reason, even as fuel costs soared 65.8%, operating income reached $1.51 billion, up 17.4% — meaning the spike in fuel expense and the spike in revenue are largely two sides of the same coin. Net income was $1.00 billion (+20.9%).

First-half free cash flow came in at $1.617 billion, up 3.6x from $444 million a year earlier. The company itself attributes the bulk of the increase to: ① a concentration of deferred income tax payments in the prior-year period, ② the completion of Blue Ridge corridor reconstruction work (approximately $295 million in the prior year), which reduced capex, and ③ earnings growth — in that order. Much of the 3.6x gain is therefore a prior-year base effect, not structural improvement.
