Nasdaq OMX and IntercontinentalExchange (ICE) dropped their $11.1 billion bid for rival exchange NYSE Euronext after it became clear the deal would not gain approval from U.S. antitrust regulators. The companies first offered to buy the New York Stock Exchange parent on April 1, aiming to curb a proposed friendly merger with Deutsche Boerse that was worth $10.2 billion when first announced in February. Deutsche Boerse responded to the news of the dropped bid by saying it plans to continue to pursue a merger with the Big Board parent.

In other exchange merger news, a consortium of Canadian banks and pension funds launched a $3.7 billion bid for TMX Group in the hopes of keeping Canada’s largest stock exchange from falling under foreign ownership. The bid tops a $3 billion offer for the exchange operator from the London Stock Exchange (LSE). The LSE said it remains committed to its own merger proposal with the TMX despite the higher rival offer, but should its bid fail it could find itself to be a takeover target, analysts said.
