Analysis
Union Pacific (UNP) experienced significant volume and cost headwinds following the introduction of the April 2025 "Liberation Day" tariffs. The company specifically cited tariff-related uncertainties as a primary driver for declines in key segments, including automotive and iron ore. In the premium segment, automotive freight revenue decreased 2% to $2.4B in FY2025, primarily due to production reductions stemming from trade policy volatility. Similarly, within the industrial segment, Metals & Minerals volumes were pressured by lower iron ore shipments directly attributed to tariff concerns (Annual Report FY-2025).
Input costs also rose as a result of the new trade regime. UNP's purchased services and materials expenses increased by $106M in 2025, with management identifying "tariff-related material expenses" as one of the three major drivers of this inflation. These increased costs were partially offset by company-wide productivity initiatives and improvements in network fluidity, which allowed for a 3% reduction in headcount despite handling a 1% increase in overall carloads.
The company's Mexico business, which represents $2.9B in annual revenue, acted as a partial stabilizer. While grain exports to China were significantly pressured by retaliatory measures, UNP was able to pivot by increasing grain shipments into Mexico. Despite this offset, total Mexico revenue declined 1% year-over-year as core pricing and mix were impacted by the broader global trade environment (Transcript FY-2025).
Looking toward 2026, Union Pacific has issued a more conservative earnings outlook than its long-term targets, projecting mid-single-digit EPS growth compared to its prior goal of high-single to low-double digits. This softer guidance reflects anticipated ongoing "volume and cost headwinds" and deteriorating macroeconomic estimates for industrial production and auto sales, driven in part by continued trade policy uncertainty (Annual Report FY-2025).

Purchased services and materials increased 4% in 2025 compared to 2024 driven by inflation (including tariff-related material expenses).
Automotive volumes declined due to reduced OEM production, driven by softer consumer demand and ongoing quality holds... [and] tariff uncertainties in the first half of 2025.
The retaliatory tariffs on grain southbound into Mexico would certainly be the other piece that comes to my mind [regarding tariff risks].
