CIX’s contract termination schedule has been confirmed, bringing the group’s official team activities to a close after nearly seven years. C9 Entertainment announced through the group’s official fan cafe on April 29, 2026, that CIX will stop operating as a team, with each remaining member’s exclusive contract ending on a separate timeline.1
The development has been widely framed as a CIX disbandment, though the agency left open the possibility of future communication with the members about activities under the CIX name. The immediate facts are that BX, Seunghun, Yonghee, and Hyunsuk are all set to leave C9 Entertainment as their contracts expire, while Yonghee’s military enlistment is also scheduled for May 11.2
CIX Contract Termination Schedule

C9 Entertainment said the group will halt team activities after months of discussions with the members. In its notice, the agency stated, “CIX will now stop group activities,” and another reported version of the statement said that “halting group activities is unavoidable” at this point.13
The contract end dates are staggered. BX and Seunghun’s exclusive contracts are set to expire on April 30, 2026. Yonghee’s contract will end when he enlists on May 11, 2026, and Hyunsuk’s contract will end on May 31, 2026, after agency support for the drama he is currently filming.12
| Member | Contract status | Relevant date | Additional detail |
|---|---|---|---|
| BX | Exclusive contract ends | April 30, 2026 | Leaves C9 Entertainment as group activities stop |
| Seunghun | Exclusive contract ends | April 30, 2026 | Leaves C9 Entertainment as group activities stop |
| Yonghee | Contract ends with enlistment | May 11, 2026 | Set to enter active-duty military service/basic military training |
| Hyunsuk | Exclusive contract ends | May 31, 2026 | Company support continues through current drama filming |
The Korea JoongAng Daily reported that all four remaining members will leave C9 Entertainment as the contracts end.2 Sports Kyunghyang’s English-language report also said the agency informed fans through the official fan cafe that CIX’s team activities would conclude, with the same contract dates for BX, Seunghun, Yonghee, and Hyunsuk.4
Yonghee’s Enlistment and Member Timelines
Yonghee’s enlistment is a key part of the timing. News1 reported that he is scheduled to enlist as an active-duty soldier on May 11, 2026, and that there will be no separate official event on the day of enlistment.5 Sports Kyunghyang separately reported that C9 Entertainment was preparing a separate opportunity for Yonghee to greet fans before enlistment.4
Hyunsuk’s timeline is different from the others because of an acting schedule. Multiple reports said C9 Entertainment will continue supporting the drama he is currently filming before his contract ends on May 31.13 The available source material does not name the drama or provide further production details.
For BX and Seunghun, the contract termination date is the earliest among the four remaining members: April 30, 2026. Reports did not provide separate future agency plans for either member in the source material provided, beyond the conclusion of their exclusive contracts with C9 Entertainment.
Nearly Seven Years After Debut
CIX debuted in 2019 and is ending team activities roughly seven years later, News1 reported.5 The group had already undergone a lineup change before the latest announcement. TenAsia reported that Bae Jinyoung left CIX in August 2024 when his exclusive contract ended, after which the group continued as a four-member act and released its seventh and eighth mini albums.6
The April 29 announcement therefore concerns the remaining four-member lineup: BX, Seunghun, Yonghee, and Hyunsuk. TenAsia reported earlier on April 29 that CIX appeared likely to conclude four-member activities ahead of the group’s seventh anniversary, connecting the timing to Yonghee’s enlistment and the contract renewal period.6
C9 Entertainment’s statement also did not fully close the door on the CIX name. Reports said the agency would continue communicating with the members so that they may be able to return with music under the CIX brand in the future.13 That wording leaves the future brand possibility separate from the confirmed end of current team operations and exclusive contracts.

The confirmed status is that CIX’s official group activities under C9 Entertainment are ending, with all remaining members’ contracts scheduled to conclude between April 30 and May 31, 2026. While the agency has referred to possible future communication about CIX’s music, the current contract termination plan marks the end of the group’s active team operations at C9 Entertainment.
