Atlanta-based Intercontinental Exchange (ICE), a leading operator of global exchanges and clearing houses and provider of data and listings services, has completed its previously announced acquisition of the Chicago Stock Exchange (CHX), ICE announced on Wednesday.

Financial terms of the transaction were not disclosed.

“The financial impact of the acquisition is not material to ICE and will not impact capital return plans,” ICE says in a news release.

CHX will continue to operate as a registered securities exchange. It will also adopt the New York Stock Exchange’s trading technology, which will provide added functionality for institutional equity brokers in Chicago, ICE says.
