The chief executive of NYSE Euronext said that European Union antitrust regulators' analysis of his company's planned merger with Deutsche Börse was "fundamentally flawed," after regulators recommended blocking the deal.

Competition authorities that have come to view a planned combination of the two exchange groups' futures markets as a monopoly on European futures and options trade have ignored competing markets in off-exchange derivatives and overseas platforms, NYSE Euronext chief executive Duncan Niederauer said in a video message to his employees.
