Cortis has been named to Billboard's list of young leaders under 21 in the United States.

Billboard recently announced this year's "21 Under 21."

The list selects 21 next-generation artists by considering their industry impact and growth momentum, including album and track sales.

Cortis was the only K-pop boy group to make the list.

Billboard introduced Cortis as one of the fastest-growing acts on the Billboard charts.
