Lee Chan-jin (이찬진), head of South Korea\'s Financial Supervisory Service, said SK hynix\'s plan to list its U.S. unit Solidigm could conflict with rules on duplicate listings. He told a parliamentary audit that both the Financial Services Commission and the FSS judge the move may breach the duplicate listing framework. Authorities are awaiting a formal interpretation on whether Solidigm is subject to domestic securities filing requirements and said they would take steps where possible.

More than a month after South Korea began enforcing guidelines that ban duplicate listings in principle while allowing exceptions, some long-delayed listing reviews have resumed and IPO supply in September is expected to increase. Investor appetite for IPOs remains weak, with most newly listed firms in August trading below their offer prices. New rules impose duties on parent boards and require subsidiary independence, while market watchers cite softer demand in bookbuilding and subscriptions.
