On April 3 KST, SM Entertainment announced Mark’s official departure from NCT.

“Hello, this is SM Entertainment.

We are always grateful to the fans for their unwavering support toward NCT. 

After a lengthy and serious discussion with Mark about the future direction activities, it has been mutually agreed that Mark’s exclusive contract will come to an end on April 8 KST.

As a result, Mark will conclude his activities as a member of NCT, NCT 127, and NCT Dream.

We would like to sincerely thank Mark for that precious time, and we also cheer him on as he prepares to embark on a new beginning. 

Moving forward, NCT 127 will promote as a 7-member group with Johnny, Taeyong, Yuta, Doyoung, Jaehyun, Jungwoo, and Haechan. NCT Dream will promote as a 6-member group with Renjun, Jeno, Haechan, Jaemin, Chenle, and Jisung. 

SM Entertainment promises to continue fully supporting the members of NCT in all their activities, and we will also do our best for the fans who love NCT with unchanging devotion.

Thank you.”
