Surface Transportation Board Rejects Union Pacific-Norfolk Southern Merger Application

Overview of the Decision
On January 16, 2026, the U.S. Surface Transportation Board (STB) unanimously rejected Union Pacific's (UP) proposed $85 billion merger with Norfolk Southern (NS), deeming the application incomplete. This decision requires UP and NS to address several deficiencies in their initial 6,692-page filing submitted in December 2025, particularly concerning market-share projections and the inclusion of the complete merger agreement.
Key Deficiencies Identified
The STB's rejection was based on three primary issues:
1. Market-Share Data: The application failed to provide future market share projections that would reflect the anticipated growth and changes post-merger. The board noted that the applicants only included 2023 data, which did not adequately demonstrate the merger's potential impact on competition.
2. Incomplete Merger Agreement: The application omitted critical sections of the merger agreement, specifically terms that would allow UP to withdraw from the transaction. This lack of transparency was deemed a violation of regulatory requirements.
3. Terminal Railroad Association of St. Louis (TRRA): The application mischaracterized the TRRA's control as a minor transaction, while the STB classified it as significant, necessitating a more detailed application.
Regulatory Context
The STB's decision is significant as it marks the first major railroad merger review under stricter regulations established in 2001, which require applicants to demonstrate that their transaction would enhance competition rather than merely preserve it. The board emphasized that its ruling should not be interpreted as a judgment on the merits of a future revised application.
Responses from Stakeholders
Union Pacific's response to the STB's decision was succinct, stating, “Union Pacific will provide the additional information requested by the Surface Transportation Board.” Other Class I railroads, including Canadian National (CN) and BNSF Railway, expressed support for the STB's decision. CN highlighted that the application was missing essential information necessary for a thorough competitive analysis, while BNSF applauded the rejection based on the lack of core information critical to assessing the merger's impact.
Industry Implications
The proposed merger aims to create the first continuous transcontinental railroad, connecting UP's network in the West with NS's tracks along the East Coast. However, industry leaders have raised concerns about potential price increases for customers if the anticipated growth in shipping volume does not materialize. BNSF CEO Katie Farmer questioned the assumption that the merger would lead to significant volume growth, suggesting that it could instead result in higher costs.
What's Next?
UP and NS have until February 17, 2026, to inform the STB of their intentions regarding a revised application, which must be submitted by June 22, 2026. The STB's decision allows for a new review process once a complete application is filed, indicating that the merger's future remains uncertain.
