Canadian Pacific Railway Ltd (CP) said on Saturday it filed a formal objection with a U.S. regulator stating Canadian National Railway Co's near US$30 billion rival bid for Kansas City Southern does not qualify to be exempted from tougher merger rules.
Last week, the U.S. Surface Transportation Board (STB) granted waiver to CP's $25 billion agreed bid for Kansas City Southern, which means the deal would not be subjected to the tougher railroad merger rules the regulator put in place in 2001.
CP won the exemption based on its smaller size and analysts and shareholders have said that STB's ruling reduces the regulatory risk to CP's deal.
CP and larger rival Canadian National (CN) are in race to take over U.S. railroad Kansas City Southern (KCS), which would create the first direct railway linking Canada, U.S. and Mexico.
Either combination is seeking to benefit from the expected pick up in trade after the US-Mexico-Canada Agreement was ratified last year.
In its argument filed with the regulator on Friday, CP said CN's offer to acquire KCS should be cause for concern because of its size.
"A combined CN/KCS would greatly expand the size of the fifth largest U.S. Class 1 railroad, vastly increasing the gap between CN/KCS and ... CP," Canadian Pacific said.
CN and KCS did not immediately respond to a request for comment on CP's filing to the regulator.
CN launched an unsolicited cash-and-stock offer valuing KCS at about $29.55 billion, after CP agreed to buy KCS for about $25 billion in March.
CP has previously said it was not considering to raise its offer. KCS previously said its board has determined that CN's competing offer could be expected to lead to a "superior proposal."
