German exchange group Deutsche Boerse AG is denying that it is contemplating yet another trans-Atlantic merger effort.

The exchange issued a statement Monday insisting that it is not in merger negotiations with the Chicago-based derivatives trading firm, CME Group.

Deutsche Boerse says its primary strategic focus is on organic growth, “mainly by expanding its business into growth regions in Asia, extending its services for unsecured and unregulated markets, and expanding its combined market data and IT business.”

Last year, European regulators blocked its proposed merger with NYSE Euronext on market share concerns. Several years ago, its bid for a deal with the New York Stock Exchange also failed.
