Union Pacific (UNP): freight and trade exposure

How global shocks reach UNP

None of the tracked sector channels map to Union Pacific (Road & Rail), so only geography applies. Stories centered on the United States register as exposure, because the company is registered in the United States.

Direction is a tendency across cycles, not a forecast. Sector mapping uses the Finnhub industry classification; geography uses country of registration, not revenue by region.

What actually moves Union Pacific

Union Pacific's existing debt does not reprice with the policy rate. Total debt was $31.81 billion, all fixed, with $1.52 billion due within a year. The rate clock that is actually open is the Norfolk Southern deal. The July 28, 2025 agreement would pay about $20 billion of cash, which means new debt. As of the filing, regulators had not approved the merger. The Surface Transportation Board rejected the first application as incomplete, then accepted a revised one in May 2026. The review was still pending in early October 2026.

Oil looks like the obvious railroad risk and mostly is not, because fuel surcharges pass the cost through, with about a two-month lag. Fuel surcharge revenue was $2.3 billion. The lag can still distort a quarter. Trade is the demand channel. Mexico traffic was $2.9 billion. A significant share of revenue moves goods to and from Mexico, Canada and Southeast Asia, including through West Coast ports. The filing says 2025 import tariffs already hurt demand and raised the cost of some purchases.

Conflict matters when it closes those Asia lanes. The less obvious domestic risk is labor. About 83% of the workforce is in 13 major rail unions.

What Union Pacific sells and where it earns

Union Pacific runs a freight railroad connecting 23 states in the western two-thirds of the country and is the only railroad serving all six major Mexico gateways. Operating revenue in 2025 was $24.51 billion, and $23.22 billion of that was freight. Industrial, covering construction materials, chemicals, plastics, forest products, metals and petroleum, brought in $8.60 billion. Bulk, mainly grain, fertilizer, food, coal and renewables, contributed $7.59 billion. Premium, which is finished vehicles, auto parts and intermodal containers, added $7.03 billion. Freight revenue grew 1%, or 3% excluding fuel. Fuel surcharges generated $2.3 billion of freight revenue, and the filing says they trail fuel price moves by about two months. Every dollar is booked in the U.S., but a significant portion moves to or from Mexico, Canada and Southeast Asia, and Mexico traffic alone was $2.9 billion. About 83% of the workforce belongs to 13 major rail unions. The bigger story is Norfolk Southern. Under a July 28, 2025 merger agreement, each Norfolk Southern share would receive one Union Pacific share plus $88.82 in cash, about $20 billion of cash in total. As of the filing, the STB had rejected the first application as incomplete in January 2026; a revised application was accepted as complete in May 2026, and the review was still pending as of early October 2026.

Customer concentration

The 10-K does not identify any customer as material to revenue. Its concentration point is trade lanes: it warns that "a significant portion of our revenues" involves moving commodities to and from Mexico, Canada and Southeast Asia, including China.

Debt

Total debt was $31.81 billion at December 31, 2025, of which $1.52 billion was due within one year. The filing states that at both December 31, 2025 and 2024 Union Pacific "did not have variable-rate debt," so all of it is fixed rate. The Norfolk Southern deal would add new debt to fund about $20 billion of cash consideration.

Risk factors that moved this year

• The Norfolk Southern merger is new. Completion depends on STB approval. As of the filing, the first application had been rejected as incomplete in January 2026, and either side can walk away if the deal has not closed by January 28, 2028, subject to extension. Since then the STB accepted a revised application in May 2026 and set a review schedule in August 2026 without ruling on the merits.
• Tariffs moved from possibility to fact. The filing says incremental import tariffs adversely affected demand for its services and raised its costs for purchased goods during 2025, may continue to do so in 2026, and could raise the cost of rail purchases.

How this changes the exposure read

Union Pacific looks like a domestic transport name, and oil shocks would seem to be its main risk. They are not, because fuel surcharges pass most fuel cost through, with about a two-month lag that moves quarterly results. Trade/tariff is the real channel: Mexico traffic was $2.9 billion, international intermodal runs through West Coast ports, and the company says 2025 tariffs already hurt demand. Conflict risk matters through those same Asia trade lanes. Chip/export rules barely touch it. Rates/Fed matter for financing the roughly $20 billion cash portion of the Norfolk Southern deal rather than for existing debt, which is all fixed. Credit stress is mild.
