Union Pacific Corporation (NYSE: UNP) and Norfolk Southern Corporation (NYSE: NSC) filed a nearly 7,000-page application with the Surface Transportation Board (STB) on Dec. 19, 2025, seeking approval for a reported $85 billion merger.

STB Review Opens Amid Rival Objections
The companies signed the merger agreement on July 29, 2025, and announced an analyst call for Dec. 19. Their joint filing describes a combined network spanning about 50,000 route miles across 43 states, connecting more than 100 ports. Union Pacific operates in 23 western states, while Norfolk Southern covers 22 eastern states.
The application includes roughly 2,000 stakeholder support letters and cites about 99% shareholder approval. The companies argued the merger would enhance competition, deliver public benefits, strengthen supply chains, and reach underserved markets.
Canadian National challenged the filing, stating it fails to show the merger would improve competition or generate significant public benefits. Canadian Pacific Kansas City said it would review the application for compliance with the STB’s 2001 Major Merger Rules.
The filing and immediate rival objections set the stage for a contested review under the STB’s merger framework, with the companies’ public-benefit case facing competitive and procedural challenges.
