Nasdaq said it has agreed to sell its struggling energy-futures business, NFX, to a unit of German exchange group Deutsche Börse, giving up on its four-year effort to break into commodities.

NFX’s core assets — including its oil, gas, electricity, metals and freight futures markets — will be transferred to Deutsche Börse’s energy arm, EEX Group, by 2020 as part of the transaction, Nasdaq and EEX said in a joint statement Tuesday. The terms of the deal weren’t disclosed.
