Key highlights:
- South Korean financial officials are worried that Solidigm, SK Hynix’s subsidiary, might break rules if it lists in the US while SK Hynix is already on the local stock exchange.
- Solidigm may launch its IPO as early as 2027, possibly reaching a value of $150 billion.
- In July 2026, South Korea set stricter dual-listing rules to better protect minority shareholders.
- The Financial Services Commission still needs an official ruling on whether Solidigm’s IPO would require registration in South Korea.
South Korea’s push for better shareholder protection is causing uncertainty about Solidigm’s plans to enter the US stock market. At a parliamentary hearing on October 19, Lee Chan-jin, head of the Financial Supervisory Service, said regulators are checking if Solidigm’s IPO clashes with South Korea’s dual-listing restrictions. His comments make it clear regulators are still asking questions as discussions about the IPO continue.
The debate mainly focuses on what happens when a subsidiary tries to list separately while its parent company is already publicly traded. With Solidigm possibly looking at a $150 billion valuation, the IPO puts SK Hynix investors’ rights in the spotlight. Regulators are examining what conditions could apply, and SK Hynix said it’s thinking about ways to protect its shareholders.
Regulators Examine Whether Solidigm’s US Listing Would Breach Domestic Rules
Speaking before lawmakers on October 19, Lee said both the Financial Services Commission (FSC) and Financial Supervisory Service (FSS) believe Solidigm’s IPO could break dual-listing rules. He answered a question about how officials plan to protect SK Hynix’s minority shareholders if Solidigm lists in the US.
But the regulatory review isn’t finished yet, and not all requirements for the IPO are clear. Lee mentioned the FSC is still waiting for an official interpretation to see if domestic securities registration rules apply.
This detail matters because it could affect what Solidigm and SK Hynix need to do next. Regulators are asking how current restrictions would work and what kind of protection SK Hynix shareholders should get.
Lee’s October 19 comments mean the IPO faces closer scrutiny, but they don’t mean the deal is cancelled. What happens next depends on how officials interpret the rules and apply them to Solidigm’s plan.
July 2026 Rules Put Minority Shareholder Consent at the Centre
South Korea made dual-listing rules tougher in July 2026 to protect minority shareholders. Now, boards must get minority shareholders’ approval before listing subsidiaries in Korea or elsewhere.
These rules matter for Solidigm because it wants to list in the US, while SK Hynix is already listed in Korea. Regulators are checking if the plans match up with these restrictions and whether investors will be protected.
Minority shareholders now play a bigger role in this discussion. SK Hynix investors might worry a separate Solidigm listing could affect their stake in the parent company. So, regulators are focusing not just on where the IPO happens, but also on what safeguards should protect those investors.
SK Hynix said earlier in October it’ll look at ways to protect shareholders if Solidigm moves ahead with its IPO. The company confirmed it’s thinking about shareholder protection, but hasn’t given more details.
Potential $150 Billion Valuation Draws Attention to IPO Plans
Reuters reported in September that Solidigm is considering an IPO as early as next year, possibly valuing the US unit at $150 billion. That puts the potential listing in 2027, though there’s no official date yet.
Such a high valuation means the IPO matters a lot financially, but regulatory questions leave the process uncertain. What the Financial Services Commission decides will be key in setting the terms.
SK Hynix didn’t comment on October 19. For now, the IPO is under review, with authorities focused on dual-listing rules, possible registration requirements, and minority shareholder protection as they figure out what will happen next.
