Marathon Petroleum Corporation modified six risk factors between its 2025 and 2026 10-K filings while maintaining 38 unchanged risks, indicating selective refinement rather than fundamental shifts in its risk profile. The most notable modifications addressed labor disruption risks from unionized workforce segments and regulatory compliance costs related to evolving environmental policies, particularly regarding potential changes to federal government oversight. These updates reflect Marathon's response to heightened labor market dynamics and regulatory uncertainty rather than the introduction of entirely new risk categories.

Approximately 3,800 of our employees are covered by collective bargaining agreements with expiration dates ranging from 2027 to 2031. Approximately 700 of those hourly represented employees in California are covered by collective bargaining agreements that were set to expire on January 31, 2026. The parties agreed to continue those agreements beyond expiration, subject to a 24-hour termination notice by either party, while successor agreements are negotiated and ratified. These agreements may be renewed at an increased cost to us. In addition, we have experienced in the past, and may experience in the future, work stoppages as a result of labor disagreements. Any prolonged work stoppages disrupting operations could have a material adverse effect on our business, financial condition, results of operations and cash flows. In addition, some states in which we operate require refinery owners to pay prevailing wages to contract craft workers and restrict refiners’ ability to hire qualified employees to a limited pool of applicants. Legislation or changes in regulations could result in labor shortages, higher labor costs, and an increased risk that contract workers become joint employees, which could trigger bargaining issues, and wage and benefit consequences, especially during critical maintenance and construction periods.
