4 terms

Memorandum of Understanding regulatory

"the signing of a binding Memorandum of Understanding that will strengthen rail service"

A memorandum of understanding (MOU) is a formal agreement between two or more parties that outlines their shared intentions and plans to work together. It acts like a handshake in writing, clarifying each side’s roles and expectations before any official contract is signed. For investors, an MOU signals that parties are serious about collaboration, which can influence future business opportunities and potential growth.

operating rights technical

"provides Union Pacific with expanded operating rights over CN’s Elgin, Joliet & Eastern Railway corridor"

A legal permission or contract that allows a company to run and manage a specific asset, operation, or service—such as a power plant, pipeline, toll road, or mining site—under defined terms, conditions, and time limits. It matters to investors because these rights determine who collects revenue, who bears operating costs and regulatory obligations, and how long control lasts; think of it like a lease that grants the keys, rules, and responsibilities for running a business asset.

forward-looking statements regulatory

"constitute “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.

Elgin, Joliet & Eastern Railway (EJ&E) corridor technical

Forward-Looking Statements

Certain statements by CN and Union Pacific included in this news release constitute “forward-looking statements” within the meaning of the United States Private Securities Litigation Reform Act of 1995 and under Canadian securities laws. By their nature, forward-looking statements involve risks, uncertainties and assumptions. The companies caution that their assumptions may not materialize and that current economic conditions render such assumptions, although reasonable at the time they were made, subject to greater uncertainty. Forward-looking statements may be identified by the use of terminology such as “believes,” “expects,” “anticipates,” “assumes,” “outlook,” “plans,” “targets,” or other similar words. Forward-looking statements reflect information as of the date on which they are made. The companies assume no obligation to update or revise forward-looking statements to reflect future events, changes in circumstances, or changes in beliefs, unless required by applicable securities laws.
