## Description

Union Pacific filed an $85 billion merger application with the Surface Transportation Board on Dec. 19, 2025, seeking to acquire Norfolk Southern and create the first transcontinental railroad since the 19th century. The STB rejected the initial application as incomplete on Jan. 16, 2026. UP plans to refile a revised application by April 30. If accepted for review, the combined railroad would create 10,000 single-line service lanes and claims it would divert 2 million truckloads annually from highway to rail. The STB has set a June 22, 2026 deadline for any refiled application.

## Resolution criteria

Resolves YES if the Surface Transportation Board formally accepts the revised Union Pacific-Norfolk Southern merger application and initiates a full substantive review proceeding (i.e., sets a procedural schedule for merits review) by December 31, 2026. Resolves NO if the application is rejected again, withdrawn, or no accepted application enters substantive review by year-end.

## Market note

While STB accepted the companies' merger application, it said May 28 that it would put further review on hold until additional information is submitted. UP and NS have until July 27 to address.
