IntercontinentalExchange, Inc, based in Atlanta, is the new owner.
There will be dual headquarters in New York and Atlanta and ICE will open an office in Manhattan. NYSE CEO Duncan Niederauer will become president of the combined company and CEO of NYSE Group.
ICE said that the tie-up will create a top exchange operator covering a diverse lineup of markets and boosting efficiency.
“We believe the combined company will be better positioned to compete and serve customers across a broad range of asset classes by uniting our global brands, expertise and infrastructure,” said IntercontinentalExchange Chairman and CEO Jeffrey Sprecher. “With a track record of growth and returns, clearing and M&A integration, we are well positioned to transform our combined companies into a premier global exchange operator that remains a leader in market evolution.”
