SK hynix funds U.S. chip plant with internal cash after dropping Solidigm sale

The semiconductor sector faced renewed volatility this week as major players adjusted their capital strategies. On Friday, October 23, SK hynix announced it would not proceed with an initial public offering for Solidigm, its U.S.-based enterprise solid-state drive subsidiary.

SK hynix attributed the decision to unfavorable stock market conditions and a recent downward trend in semiconductor share prices. The company stated that current market conditions would prevent Solidigm from achieving a valuation that fairly reflects its growth outlook. Consequently, SK hynix ended its review of both a pre-IPO financing round and a full listing.

The parent company confirmed that the cancellation of the listing does not alter its expansion plans. SK hynix intends to build a new fabrication plant for Solidigm in the United States to meet rising demand for enterprise storage. The company has not yet disclosed the facility's size, total cost, or construction timeline.

Solidigm manufactures high-capacity data center drives using floating gate 3D QLC NAND memory. As artificial intelligence infrastructure expands, demand for this storage technology is climbing faster than current production capacity can supply. A new American plant would also expand SK hynix's manufacturing footprint in the U.S., a factor that carries weight in the ongoing push for domestic chip production.

SK hynix previously considered several funding routes, including direct investment and external financing. An offering would have allowed the company to raise capital without adding debt. It could also have signaled the subsidiary's value, which SK hynix believes is not fully reflected in its own market capitalization.

Analysts note that enterprise SSD demand is at a record high, and modern 3D NAND facilities can cost tens of billions of dollars. Outside funding might have eased pressure on SK hynix's balance sheet. However, Solidigm's profitability offers an alternative path. Micron's enterprise storage division recently reported a non-GAAP gross margin of 90%. Solidigm, which holds a 21.1% share of the enterprise SSD market, may earn comparable or higher margins due to exclusive products.

If these high margins persist, the unit could generate substantial cash flow for SK hynix. The company may fund the U.S. expansion through a mix of internal cash and debt. This approach allows SK hynix to retain full ownership of the subsidiary rather than selling a stake at a valuation it considers too low.
