CSX

CSX is a high-quality Class I franchise — 32.1% operating margin, 20.5% net margin and 22.0% ROE still mark it as one of the better businesses in any sector. But the trajectory is what matters, and it is clearly negative. Revenue has slid for three straight years from the 2022 peak ($14.9B → $14.7B → $14.5B → $14.1B), and FY2025's $14.1B was down 3.1%. Profitability is deteriorating faster than the top line: net income fell 16.7% to $2.89B (down from $4.11B in 2022) and diluted EPS dropped 14% to $1.54. Management's own 2025 highlights spell out the squeeze — expenses rose 3% to $9.6B even as revenue fell 3%, dragging operating margin down a full 400bps to 32.1% from 36.1%. That is operating deleverage, not a one-off.

The valuation does not reflect any of this. At $45.63 the stock trades at 29.6x trailing EPS and 6.0x sales — multiples you pay for a compounding grower, not a railroad whose earnings are shrinking. Cash generation is also tightening: operating cash flow fell 12.1% to $4.61B while capex climbed 14.7% to $2.90B, compressing free cash flow to roughly $1.7B, and the company responded by cutting buybacks 37.6% to $1.40B. Cash on hand fell 28.2% to $670M. None of this is distress — leverage at 2.32x liabilities/equity is normal for a capital-intensive rail and equity grew 5.2% — but it removes the support a premium multiple needs.
