Union Pacific and Norfolk Southern submit merger data

• Union Pacific and Norfolk Southern submitted their initial phase of regulatory data to the Surface Transportation Board.
• The federal filing addresses regional railroad interchange control concerns, holding up the pending transaction review.
• Both partners offered to divest localized rail stakes to preserve logistical market neutrality and secure antitrust clearances.

Union Pacific (NYSE:UNP) and Norfolk Southern (NYSE:NSC) submitted the first portion of informational data requested by the Surface Transportation Board to advance their pending $85 billion railroad merger.

The regulatory transaction update follows an administrative delay that stalled the formal evaluation and environmental review of the multi-billion dollar logistics combination.

"In particular, for the TRRA, the filing provides clear evidence that the other Class I railroads who are vocally opposing the merger are using the TRRA as a pawn in their efforts to stop or delay the merger," the companies stated in a joint corporate release.

The initial submission directly addresses administrative questions regarding independent control over localized shipping networks, including the Terminal Railroad Association of St. Louis and Kansas City Terminal Railway.

Following the announcement, Union Pacific's share price was up at $283.07.

The partnership reiterated that it remains committed to executing structural integration strategies to achieve a targeted mid-2027 completion of the transaction.

The multi-carrier consolidation plan was originally logged inside federal registers during the initial filing phase completed back in December 2025.
