Key Terms

surface transportation board, major merger rules, public interest review

3 terms

surface transportation board regulatory

"merger application filed by Union Pacific (UP) and Norfolk Southern (NS) with the Surface Transportation Board (STB)"

A federal agency that oversees and enforces rules for freight railroads and related transport services, acting like a referee for the industry by settling disputes, reviewing rates and service complaints, and approving major changes such as mergers or line abandonments. Investors care because the board’s decisions can change a railroad’s costs, access to markets, and competitive landscape, which in turn can affect revenue, profitability and long-term investment value.

major merger rules regulatory

"Whether it complies with the Board's 2001 Major Merger Rules and provides the STB"

Major merger rules are the government requirements and review steps that large corporate takeovers must meet before they can proceed, like traffic rules for big deals that ensure they won’t harm competition or national interests. Investors care because these rules can delay, change, or block transactions and impose conditions that affect the combined company’s future profits, debt load, and stock value — similar to how a red light or detour can change travel plans and costs.

public interest review regulatory

"its public interest review will entail consideration of a broad and novel array of public interest concerns"

A public interest review is a government or regulator assessment of a proposed corporate action—such as a merger, acquisition, foreign investment, permit or service change—to decide whether it could harm safety, competition, consumers, national security or other community priorities. It matters to investors because the review can delay, block or force changes to a deal or business plan, creating legal uncertainty and potential financial impact; think of it like a safety inspection that can approve, require fixes, or stop a project.

CALGARY, AB, Dec. 19, 2025 /PRNewswire/ - Canadian Pacific Kansas City (TSX: CP) (NYSE: CP) (CPKC) today released the following statement regarding the merger application filed by Union Pacific (UP) and Norfolk Southern (NS) with the Surface Transportation Board (STB) on Dec. 19, 2025:

CPKC has only just obtained the lengthy UP-NS merger application formally filed today and will be thoroughly reviewing it over the coming days. We will be examining the application from at least two perspectives: 

• Whether it complies with the Board's 2001 Major Merger Rules and provides the STB and interested parties an adequate basis for evaluating the public interest consequences of the UP-NS proposal.
• Whether the UP-NS proposal is consistent with the public interest.

The first step in the STB's merger review process calls for the STB to determine, by Jan. 18, 2026, whether to accept the application for consideration or to reject it as incomplete.

If the STB accepts the application, its public interest review will entail consideration of a broad and novel array of public interest concerns. Approval of this merger is not inevitable.

The proposed UP-NS merger, unprecedented in scale and scope, would radically and permanently change the U.S. rail network. If approved, the merger would pose extraordinary and far-reaching risks to customers, rail employees and broader supply chains. We are confident the STB will conduct a vigorous process to assess all of the short- and long-term public interest impacts of the proposed behemoth, including on the competition rail customers have today.

CPKC will remain an active participant in that process. We encourage all interested shippers, receivers, associations, governments and other stakeholders to closely examine the application and file their own comments with the STB. All stakeholders should express their views about how this proposed merger would affect their business, including new limitations on their rail shipping options, new risks of rate pressures, and new risks to service quality. CPKC anticipates submitting comments to the STB in accordance with the procedural schedule the STB adopts in this proceeding.
