SK Hynix weighs U.S. IPO for Solidigm as ownership concerns hit Korean chip stocks

SK Hynix is reviewing a potential U.S. initial public offering for its American NAND Flash subsidiary Solidigm, a move Bloomberg said could value the company at as much as $100 billion and come as early as next year. The report triggered a sharp market reaction in South Korea. SK Hynix fell 5%, marking its biggest one-day drop in nearly two weeks, while its largest shareholder SK Square dropped more than 8% and holding company SK Inc. lost more than 6%. The proposed listing has drawn scrutiny over the group’s layered ownership structure. The Korea Corporate Governance Forum said in August that SK Hynix should abandon the plan, arguing that Solidigm is held indirectly through the U.S. unit AI Company, making it a sub-subsidiary and deepening an already pyramid-style structure if listed separately. That has fueled concerns about duplicate listings and shareholder dilution. Jung In Yun, chief executive of Fibonacci Asset Management Global, said investors should stay cautious rather than panic. In his view, a U.S. listing could unlock Solidigm’s value and raise funds for capacity expansion, but existing SK Hynix shareholders would also give up part of the unit’s future earnings. He said the outcome depends on the final valuation and how the proceeds are used. Rising oil prices have also added pressure, pushing risk-off sentiment higher and weighing on Korean semiconductor names including Samsung Electronics.
