On March 30, SM Entertainment denied the current rumors about EXO’s comeback dates. They said, “EXO will not be making a comeback in May. Their comeback date has not yet been set.”

They added, “The concert at the end of May is only an encore concert for the tour that they are currently on, not a performance that marks the beginning of a comeback.”

On May 27 and 28, EXO will be performing two encore concerts called “EXO PLANET #3 – The EXO’rDIUM[dot] –” in Seoul, at the Olympic Stadium. They are special concerts to mark the end of their third solo concert tour, “EXO PLANET #3 – The EXO’rDIUM,” which began last July.

Meanwhile, EXO’s next stop on this tour is the Singapore Indoor Stadium on April 2.
