CIX are bringing their run to a close. C9 Entertainment confirmed on 29 April that the group will cease all team activities, with members' contracts expiring across the next five weeks in a staggered wind-down that leaves little ambiguity about what comes next.

In a statement posted to the group's official fan café, the agency said that over the past several months it had held thorough discussions with the members about the group's future. The conclusion was unambiguous: under the current circumstances, suspending operations as a team was unavoidable.

BX and Seunghun's contracts conclude on 30 April. Yonghee, who has applied for voluntary early enlistment, will enter a military training centre on 11 May – his contract ending the same day. C9 confirmed it is preparing a small fan gathering so FIX can say goodbye to him before he reports for duty. Hyunsuk, currently in the middle of filming a drama with the company's full support, will see his contract run to 31 May.

The news marks the end of a group that debuted in July 2019 with the EP Hello Chapter 1: Hello, Stranger and lead single "Movie Star" – a release that sold 70,000 copies within two months and saw CIX win on The Show within a week of their showcase. They built a dedicated international fanbase through a run of releases including "Numb," "Cinema," and "WAVE," and were C9 Entertainment's first ever boy group.

The ending had been signalled. In August 2024, C9 announced Bae Jinyoung's departure after his contract expired on 1 August. Their last release as a quintet had been the single album 0 or 1 in January 2024. The remaining four members pressed on, and in September 2025 released GO Chapter 1: GO Together – their eighth EP and the opening instalment of a planned trilogy. The series was designed to complete the narratives running through their earlier HELLO and OK album arcs, with BX describing the new direction as a story of receiving salvation and heading toward the group's own version of heaven. That trilogy will now remain unfinished. For now, GO Chapter 1 is where the story stops.

The EP's title track "WONDER YOU" reached eight million YouTube views within four days of release. At the time, Yonghee said the phrase "GO Together" was chosen after the four members had talked at length about moving forward as a quartet, and agreed to give their best side by side against whatever came next. Seven months later, this is what came next.

C9 did not rule out a return entirely. The statement closed with the agency expressing hope that the name CIX may one day come back with its own unique music – standard preservation language, though delivered with what read as genuine regret rather than formality. Both the members and the company, the statement said, had always approached CIX with genuine dedication across every aspect of what the group did. Whether that amounts to anything more than a goodbye remains to be seen.
