“We transport hazardous materials – We transport certain hazardous materials and other materials, including crude oil, ethanol, and toxic inhalation hazard (TIH) materials, such as chlorine, that pose certain risks in the event of a release or combustion. Additionally, U.S. laws impose common carrier obligations on railroads that require us to transport certain hazardous materials regardless of risk or potential exposure to loss.”

“As fuel prices fluctuate, our fuel surcharge programs trail such fluctuations in fuel prices by approximately two months and are from time-to-time a significant source of quarter-over-quarter and year-over-year volatility, particularly in periods of rapidly changing prices.”

“Table of Contents Financial risks We are affected by fluctuating fuel prices – Fuel costs constitute a significant portion of our transportation expenses. Diesel fuel prices can be subject to dramatic fluctuations, and significant price increases could have a material adverse effect on our operating results.”

“Strategic and operational risks We must manage fluctuating demand for our services and network capacity – Significant reductions in demand for rail services with respect to one or more commodities or changes in consumer preferences that affect the businesses of our customers can lead to increased costs associated with resizing our operations, including higher unit operating costs and costs for the storage of locomotives, rail cars, and other equipment; workforce adjustments; and other related activities, which could have a material adverse effect on our results of operations, financial condition, and liquidity.”

Annual report 2025A · The company itself

“If there is significant demand for our services that exceeds the designed capacity of our network or shifts in traffic flow that are contrary to the designed capacity of our network, we can experience challenges, including congestion and reduced velocity, that could compromise the level of service we provide to our customers. This level of demand also can compound the impact of weather and weather-related events on our operations and velocity.”

“A significant portion of our revenues involves transportation of commodities to and from international markets – Although revenues from our operations are attributable to transportation services provided in the U.S., a significant portion of our revenues involves the transportation of commodities to and from international markets, including Mexico, Canada, and Southeast Asia, by various carriers and, at times, various modes of transportation. Significant and sustained interruptions of trade with Mexico, Canada, or countries in Southeast Asia, including China, could adversely affect customers and other entities that, directly or indirectly, purchase or rely on rail transportation services in the U.S. as part of their operations, and any such interruptions, including international armed conflicts, such as the Russia-Ukraine and Israel-Hamas wars, could have a material adverse effect on our results of operations, financial condition, and liquidity.”

“Many movements face product or geographic competition where our customers can use different products (e.g., natural gas instead of coal, sorghum instead of corn) or commodities from different locations (e.g., grain from states or countries that we do not serve, crude oil from different regions). Sourcing different commodities or different locations allows shippers to substitute different carriers, and such competition may reduce our volumes or constrain prices.”

“Severe weather and natural events could result in significant business interruptions and expenditures – As a railroad with a vast network, we are exposed to severe weather conditions and other natural phenomena, including earthquakes, hurricanes, fires, floods, mudslides or landslides, extreme temperatures, avalanches, and significant precipitation, and climate change may cause or contribute to the severity or frequency of such weather conditions. Line outages and other interruptions caused by these conditions have in the past and could in the future adversely affect parts or all of our rail network, potentially negatively affecting revenues, costs, and liabilities, despite efforts we undertake to plan for these events.”

“We have experienced and will likely continue to experience varying degrees of cyber incidents in the normal course of business. There can be no assurance that the resources we devote to protect our technology systems and proprietary data or the systems we have designed to identify, prevent, or limit the effects of cyber incidents will be sufficient to prevent or detect such incidents, or to avoid a material adverse impact on our systems after such incidents do occur. Furthermore, due to the rising numbers and increasing sophistication of cyber-attacks, an increasingly complex information technology supply chain, and the nature of zero-day exploits, we may be unable to anticipate or implement adequate measures to prevent a security breach, including by ransomware or as a result of human error or other cyber-attack methods, from materially affecting our systems or the systems of third-parties upon which we rely.”

“Additionally, we utilize a limited number of steel producers that meet our rail specifications. Rail is critical to our operations for rail replacement programs, maintenance, and for adding additional network capacity, new rail and storage yards, and expansions of existing facilities. This industry similarly has high barriers to entry, and if there is any significant consolidations or mergers in this industry, or one of these suppliers discontinues operations for any reason, including bankruptcy or insolvency, we could experience both significant cost increases for rail purchases and difficulty obtaining sufficient rail for maintenance and other projects.”
