Canadian Pacific Kansas City reported Q4 2025 operating ratio of 55.9%, driving full-year OR to 59.9%—the first time the company has operated below 60%. Management guided to 100 basis points of annual OR improvement going forward.

The earnings call disclosed three specific volume drivers for 2026:

Record grain harvest: Canada harvested 85 million metric tons of grain in 2025 versus the previous record of 78 million tons, a 9% increase. Management characterized this as a "strong differentiating base business" providing idiosyncratic volume growth.

Southeast Mexico Express (SMX) launch: CP announced a new intermodal product with CSX targeting Dallas/Atlanta-to-Mexico lanes, claiming 4-day transit time advantage versus truck. Management stated that a single client committed to 80,000 loads in year one, with the product launching within months.

Americold ramp-up: The Kansas City temperature-controlled intermodal facility is operational, with the Saint John facility scheduled to open in July 2026.

Management guided to mid-single-digit revenue ton mile (RTM) growth and low double-digit EPS growth for 2026, with a 5% share buyback program. Capital expenditures will decline 15% to $2.65 billion as merger integration spending completes.

Two disclosed headwinds: tariffs are expected to reduce revenue by $200 million (1-1.5% of revenue/RTMs), concentrated in Q1-Q2, and management spent significant call time discussing the proposed Union Pacific-Norfolk Southern merger. Despite claiming to be "not concerned," the CEO detailed potential competitive threats and emphasized the need for "concessions" and "enforceable relief" in any regulatory approval.

Norfolk Southern's Q4 earnings call independently corroborated CP's competitive positioning, with NSC reporting a 7% decline in intermodal volume attributed to competitive losses to CP and CSX during NSC's merger distraction.

The operating ratio inflection from above 60% to sustained sub-60% levels, combined with quantified new revenue from SMX (80,000 loads at typical intermodal rates of $2,000-3,000 per load implies $160-240 million in year-one revenue) and organic volume growth from record grain harvests, represents margin expansion driven by company-specific execution rather than sector trends.
