SK Hynix Suspends Solidigm U.S. IPO Review, Citing Market Volatility and Regulatory Scrutiny

SK Hynix said on Friday, October 23, 2026, that it had suspended its review of a U.S. initial public offering for Solidigm, its American NAND flash memory and solid-state drive subsidiary, citing financial market volatility and share price trends, Reuters reported. The decision came days after South Korea's financial regulators said a listing could conflict with the country's rules on separate listings of parent companies and subsidiaries.

What the company said

"This decision does not reflect any change in Solidigm's growth prospects or investment needs," SK Hynix said in a statement. The South Korean chipmaker said it would continue to explore ways to fund Solidigm's expansion and enhance shareholder value, including reviewing the timing, scale and financing of future investments.

The company said increased market volatility and a broader correction in semiconductor stocks had prompted it to reconsider the listing despite strong business performance at both SK Hynix and Solidigm. It said a listing could have raised external capital to fund new production facilities while supporting shareholder returns through dividends, buybacks and share cancellations, and could have helped investors recognize Solidigm's growth potential, which it said was not fully reflected in the parent's valuation.

Size of the shelved deal

People familiar with the plans had said the share sale could have raised $15 billion and valued Solidigm at $150 billion, according to Reuters. A listing had been under consideration to help fund a new U.S. factory and meet demand for memory chips used in AI data centers. Earlier market speculation, reported by The Korea Times on October 19, had put a potential raise at $10 billion and a valuation of up to $100 billion. Reports that Solidigm had appointed IPO underwriters and set up a government affairs team had added to expectations of a listing, the newspaper said.

Solidigm, based in Rancho Cordova, California, was created through SK Hynix's $9 billion acquisition of Intel's NAND flash memory business.

Regulatory concerns in Seoul

Financial Supervisory Service Governor Lee Chan-jin told a National Assembly audit on Monday, October 19, that both the Financial Services Commission and the FSS considered the potential listing to conflict with rules governing parent-subsidiary listings, The Korea Times reported. Those dual-listing restrictions were tightened in July to strengthen shareholder protection, according to Reuters. Because overseas subsidiaries fall outside the Korea Exchange's review of such listings, the FSC was awaiting an interpretation of whether Solidigm would be subject to Korean securities filing requirements, Lee said.

The concern centered on dilution: Solidigm's earnings currently go entirely to SK Hynix, and issuing new shares to outside investors would give them a share of future earnings. The Korea Corporate Governance Forum, an independent body, welcomed the decision and said SK Hynix could instead inject capital into Solidigm, citing brokerage estimates that SK Hynix's cash holdings could reach 456 trillion won, or about $344 billion, by the end of 2027, Reuters reported.

Share performance

SK Hynix shares had fallen 31% since news of the potential listing emerged in late September, compared with a 20% decline in the benchmark KOSPI over the same period, according to Reuters. On Friday, the stock rose 1.4% in afternoon trading in Seoul while the KOSPI fell 1.4%. The company's U.S.-traded shares, which debuted on the Nasdaq in July, jumped more than 4% in midday trading in New York, CNBC reported.

U.S. investment talks

Reuters said it was not immediately clear how the decision would be received by the Trump administration, which has pressed foreign chipmakers to build U.S. plants. According to people familiar with the matter, SK Hynix has sought to link a potential U.S. factory to hoped-for approval from Washington for exports of U.S. chipmaking equipment to its operations in China, the news agency reported.
