Union Pacific and Norfolk Southern cleared a hurdle as the U.S. Surface Transportation Board said Thursday it would accept their revised filing on the planned $85 billion merger, but put the case on pause. The board told the rail firms they have to provide more information by July 27 before the main review can begin.
Deal is still on the table, but the move puts off the launch of the first coast-to-coast freight rail network in the U.S. If regulators sign off, Union Pacific would take over Norfolk Southern, bringing their routes together for roughly 50,000 miles of track across 43 states.
STB has pushed the case from a basic completeness check into a full merits review. Now the companies need to prove the merger is good for the public and improves competition. The regulator said it doesn’t back rail mergers that lower shipper options unless the public gains are clear and significant.
STB says its acceptance of the revised filing is just procedural. The Board said sections of the latest version are “unclear or underdeveloped” and warned that setting a schedule now could put an unfair burden on those needing to comment without getting more detail. Surface Transportation Board
Union Pacific and Norfolk Southern put in a revised application to the STB on April 30, following the board’s January decision to reject the original as incomplete. The latest order from the agency puts the environmental review on hold and will keep it paused until the board decides if the new details meet its requirements.
The Board requested extra information on competition, market-share forecasts, service plans, car supply and downstream impacts, which would include effects on other railroads, shippers and possible future merger pressure. The Board also wanted more details about the impacts on passenger rail.
STB says the environmental side is significant. The board plans to do a full environmental impact statement—a federal review of possible impacts. That will include at least 12 in-person public meetings and a handful of virtual meetings when the process restarts.
The shares dropped after the ruling. Union Pacific slipped 4.2% Thursday, Norfolk Southern was off 5.4%, according to Reuters. RBC’s Walter Spracklin said the delay probably doesn’t shift the approval odds, calling the news “neutral to sentiment.” Reuters
Union Pacific CEO Jim Vena said the merger promises “more reliable and lower-cost transportation options” for businesses. Norfolk Southern CEO Mark George said both companies felt better about the proposal after submitting a more detailed amended application. UP
The companies project the merged railroad will move around 2.1 million truckloads to rail a year, cut shipping costs for customers by $3.5 billion annually, and create about 1,200 net union jobs in the third year post-merger. They note over 2,000 letters backing the deal from customers, labor unions, short-line railroads, ports and business groups.
Railroad rivalry is already intense. Norfolk Southern and CSX move much of the freight in the East. BNSF and Union Pacific handle the West, with CPKC stretching its lines through Canada, the U.S., and Mexico. BNSF CEO Katie Farmer called the merger “driven by Wall Street” and claims it would “eliminate competition.” Union Pacific says the deal wouldn’t shift the overall freight market much. AP News
Union Pacific faces new risks if a pause drags out. The STB might attach conditions, slow the timetable, or kill the deal. Under the merger agreement, Norfolk Southern gets a $2.5 billion breakup fee if it collapses, and Union Pacific can walk if needed concessions top $750 million, AP reported.
After the companies file more information, the STB is likely to issue a new timeline. Reuters said the Board would get a year to review the case, plus three months to decide. The companies now see the deal closing around mid-2027.
