UNP

Union Pacific is a textbook wide-moat franchise operating at peak quality. FY2025 operating margin of 40.2%, net margin of 29.1%, and a 38.7% return on equity are best-in-class for any industrial, and the MD&A confirms the railroad is running well: operating ratio improved 10bps to 59.8%, freight-car velocity rose 8%, terminal dwell fell 8%, and the company logged its best-ever personal-injury (0.68, -24%) and derailment-rate results. Net income of $7.14B (+5.8%) and diluted EPS of $11.98 (+8.0%) were records, driven by 'core pricing gains, strong productivity, and 1% volume growth.' This is a genuinely excellent business.

The problem is the top line. Revenue of $24.5B grew just 1.1% and has effectively flatlined for four years — $24.9B in FY2022, $24.1B in FY2023, $24.3B in FY2024, $24.5B in FY2025 — meaning the 2025 record revenue still sits below the 2022 peak. Volume rose only 1%; the earnings growth is engineered through pricing, productivity, and a shrinking share count (-1.8%) rather than expanding the franchise. That makes EPS growth real but structurally capped: there is limited operating leverage left to harvest once the operating ratio is already sub-60%.
