The proposed $85 billion merger between Union Pacific (UP) and Norfolk Southern (NS), two of America's largest Class I railroads, has hit a significant regulatory obstacle. The Surface Transportation Board (STB), the federal agency overseeing rail mergers, rejected the application citing incomplete information, casting uncertainty over the potential industry-altering consolidation.
STB's Unanimous Decision
The STB issued a unanimous determination that the December merger application failed to meet the agency's requirements for comprehensive disclosure. The board emphasized this procedural rejection doesn't constitute judgment on the merger's merits, but rather reflects deficiencies in the submitted materials.
Key Application Deficiencies
The STB identified multiple shortcomings in the filing:
- Incomplete system impact analysis: The application lacked detailed projections of post-merger market share, specific revenue data, and comprehensive traffic impact assessments required to evaluate competitive effects.
- Missing merger agreement documents: The filing omitted complete contractual documentation needed for full regulatory review.
- Insufficient market share forecasts: While predicting traffic growth and line transfers, the application provided only current combined market share without post-merger projections accounting for growth, diversion, and other market dynamics.
- Misclassification of St. Louis terminal control: The request to control the Terminal Railroad Association of St. Louis was improperly designated as a "non-significant" transaction.
Regulatory Process Continues
The STB clarified this decision doesn't terminate the merger process. UP and NS may submit a revised application, triggering new review procedures. The railroads must inform the STB by February 17 about their timeline for resubmission.
Industry Analyst Perspectives
TD Cowen analyst Jason Seidl noted the decision aligns with industry expectations about the application's deficiencies. "We anticipate Union Pacific will accelerate revisions, but acknowledge this setback requires additional analysis," Seidl wrote, projecting a final decision timeline extending into 2027.
Independent rail analyst Tony Hatch characterized the rejection as procedural rather than substantive. "The STB essentially agreed with complainants about missing information without ruling on the competitive enhancement claims," Hatch observed. "This will likely be addressed during substantive merger discussions rather than application review."
Competitor Opposition
Before the STB decision, competing railroads BNSF and Canadian National (CN) filed motions demanding greater disclosure from the merging parties:
- CN criticized the lack of transparency regarding potential competitive harms, stating the railroads failed to meet heightened standards for major mergers.
- BNSF argued the merger would reshape the industry for decades while the applicants avoided fundamental disclosure obligations about internal assessments of competitive impacts.
Potential Industry Impacts
If ultimately approved, the merger could transform North American rail transportation:
- Market concentration: Reducing Class I railroads from seven to six may raise antitrust concerns about reduced competition.
- Service improvements: Network consolidation could eliminate redundancies and improve efficiency, potentially enhancing reliability and coverage.
- Competitive responses: Rivals may pursue their own mergers or strategic investments to maintain competitiveness.
- Shipper effects: Impacts would vary by commodity and route, with some benefiting from improved service while others facing potential rate increases.
The STB will conduct rigorous review of any resubmitted application, balancing potential benefits against competitive concerns before determining whether the merger serves the public interest.
