SK hynix Pays Cash for New U.S. SSD Plant

Micron’s enterprise storage division recently reported a non-GAAP gross margin of 90 percent. That figure provides context for a major strategic shift announced by SK hynix early on Friday, October 23. The South Korean chipmaker decided against listing its U.S.-based enterprise SSD subsidiary, Solidigm, on public stock markets.

SK hynix stated that unfavorable stock market conditions and recent trends in semiconductor share prices made a listing unattractive. Despite cancelling the initial public offering, the company confirmed it still intends to build a new fabrication plant in the United States. This facility will produce high-capacity data center SSDs built on floating gate 3D QLC NAND memory.

The company has not disclosed the size of the new facility, its total cost, or a specific timeline for construction. Solidigm currently holds 21.1 percent of the enterprise SSD market. Demand for high-capacity storage is rising as artificial intelligence infrastructure rollouts accelerate. Solidigm's current manufacturing capacity is barely sufficient to cover these expected increases in orders.

SK hynix previously weighed several funding routes, including direct investment, a pre-IPO funding round, and a full listing. An offering would have allowed the company to bring in outside capital without adding debt. It would also have highlighted what SK hynix regards as the true value of the subsidiary, which it believes is not properly reflected in its own market capitalization. Proceeds might additionally have gone toward dividends, share buybacks, and share cancellations.

The reversal occurred because greater market volatility and an ongoing correction in chip stocks reduced the appeal of an IPO. SK hynix argued that present conditions would stop Solidigm from earning a valuation that fairly reflects its growth outlook. The company has ended its review of both a pre-IPO financing round and a listing. It will keep looking at other ways to fund the project.

The decision raises questions about balance sheet strain, given that modern 3D NAND fabs can cost tens of billions of dollars. However, Solidigm’s strong profitability may allow SK hynix to fund the U.S. expansion through a mix of internal cash and debt. This approach would let the parent company retain full ownership of the subsidiary rather than selling a stake at a valuation it considers too low.
