According to media reports on May 8, boy group HALO's contract with their label Hi-Star Media recently came to an end back in April. 

HALO, who debuted back in 2014, are made up of 6-members including Ooon, Dino, Jaeyong, Heechun, Inhaeng, and Yoondong. For the past 5 years, the group promoted with tracks such as "Fever", "While You're Sleeping", "Mariya", and most recently, with "O.M.G" released back in May of 2018.

Despite the end of their contract with Hi-Star Media, HALO will reportedly choose to continue on as a group rather than disbanding. Member Dino enlisted as an active duty soldier back in August of last year, and thus, the group will seek to promote as 5-members for the time being. 

[UPDATE] Hi-Star Media has since released an official statement regarding HALO's contract expiration. The label stated, "The contracts of HALO members Ooon, Dino, Jaeyong, Heechun, Inhaeng, and Yoondong have come to an end as of April, 2019, and we are currently in the process of discussing the members' future paths, including the path of Dino who is currently in the military."
