Union Pacific Corporation shares fell 0.6% to close at $233.11 on Tuesday, as investors digested fresh pushback from rival railroads seeking to derail the company’s merger application with Norfolk Southern on procedural grounds. Yahoo Finance+1
The filings matter because the merger is entering a gatekeeping phase at the U.S. Surface Transportation Board, the federal regulator that oversees freight-rail competition and approves major rail combinations. If the board decides the application is incomplete, the review clock effectively resets. Surface Transportation Board+1
That timing risk is front and center for Union Pacific, whose proposed tie-up with Norfolk Southern would create what the companies call the first U.S. coast-to-coast freight railroad — a strategic bet that could reshape routing options for shippers and competitive dynamics across the sector.

Canadian Pacific Kansas City, CSX and other major rail rivals urged the STB to reject the filing as incomplete, arguing it lacks required detail on competition impacts and other disclosures. Trains
Rivals highlighted the absence of the full merger agreement in the public record and said the application does not provide enough information to test the companies’ claims about benefits and competitive effects. Trains
CSX, in its submission, argued the application leans heavily on truck-to-rail arguments while not fully explaining how the deal would increase “rail-to-rail” competition — meaning competition among rail carriers themselves. Trains
Canadian Pacific Kansas City also criticized what it called missing underlying data behind the companies’ projections, including a claim that the merger would move more than 2 million truckloads a year from highways to rail, the Trains report said. Trains+1
The STB’s current step is a “completeness” review — a procedural check on whether the application contains required information, not a decision on whether the merger should be approved. The board said applicants may reply by noon ET on Jan. 2, 2026, and it will then decide whether to accept or reject the application as incomplete. Surface Transportation Board
Union Pacific Chief Executive Jim Vena signaled he expects additional requests from regulators. “There’s probably something we missed or something they need a little more information on,” he told Trains in an interview cited in the report. Trains
The stock’s decline came as U.S. equities ended slightly lower in thin, year-end trading after Federal Reserve meeting minutes underscored internal debate over the policy outlook. The S&P 500 fell 0.14% on Tuesday, Reuters reported. Reuters+1
Separately, Union Pacific said it will release fourth-quarter 2025 results on Tuesday, Jan. 27, 2026, with a conference call and webcast scheduled for 8:45 a.m. ET. Investors typically focus on volume trends, pricing, labor and fuel costs, and any merger-related expenses or timing updates. Up
Before the next session, investors will track whether Union Pacific and Norfolk Southern respond to rivals’ filings ahead of the STB’s Jan. 2 deadline and whether the board signals it wants additional data before moving to a merits schedule. Surface Transportation Board+1
Stocks are set for a full regular session on Wednesday, Dec. 31, with U.S. markets closed on Thursday, Jan. 1, for New Year’s Day; the bond market is expected to close early at 2 p.m. ET on Dec. 31, according to SIFMA’s holiday schedule. Nasdaq+1
On the chart, Union Pacific traded between $232.93 and $234.63 on Tuesday, leaving traders watching the $233 area as a near-term support zone and the mid-$234s as the first resistance level heading into year-end positioning. Yahoo Finance
