SEOUL - Hybe’s shares tumbled on April 26 as internal strife between the K-pop giant and Ador, the Hybe-owned label behind popular girl group NewJeans, deepened.

The company, which manages artists including BTS and Seventeen via more than 10 labels in South Korea and overseas, dropped as much as 5.8 per cent in early Seoul trading. A total of 1.2 trillion won (S$1.2 billion) of market value has been wiped out since the saga started earlier this week.

On April 22, Hybe said Min Hee-jin, chief executive officer of label Ador, faced an internal inquiry over an alleged attempt to seize control of the label, along with other Ador executives.

Ms Min held a two-hour press conference on April 25 denying allegations that she had tried to take control of Ador and accusing Hybe of mismanaging the label. The event was streamed live on YouTube and attracted significant public attention in South Korea.

Following the presser, Hybe refuted Ms Min’s arguments and urged her to resign immediately. A forthcoming album from NewJeans - one of Hybe’s most popular bands, whose work Ms Min produces - will launch as planned, Hybe said in a statement on April 26.

Hybe owns 80 per cent of shares in Ador, while Ms Min holds an 18 per cent stake. The parent company’s probe examines allegations that Ador executives sought to raise new funds reducing Hybe’s stake in the label and consulted with external investors and analysts.

“Regardless of whether her claims are true, suspicions about Hybe’s management ability of [its] multi-label system will become dominant,” said Yoon Joonwon, a fund manager at DS Asset Management.

Ador contributed 5 per cent of Hybe’s consolidated sales last year, said Ahn Doyoung, an analyst at Korea Investment & Securities. BLOOMBERG
