SK hynix abandons Solidigm IPO to self-fund new US storage facility

The global semiconductor industry continues to see major shifts in capital strategy. SK hynix announced on Friday morning, October 23, that it will not pursue an initial public offering for Solidigm, its American subsidiary for enterprise solid-state drives.

Company officials stated that unfavorable stock market conditions and recent trends in semiconductor share prices made a public listing unattractive. SK hynix confirmed it intends to build a new fabrication plant in the United States to meet rising demand for enterprise SSDs. The company has not disclosed the facility size, total cost, or construction timeline.

Solidigm specializes in high-capacity data center SSDs using floating gate 3D QLC NAND memory. Demand for this storage is climbing as artificial intelligence infrastructure expands. Current manufacturing capacity is barely sufficient for projected needs. A new US plant would also expand SK hynix's domestic manufacturing footprint.

The company previously evaluated several funding routes, including direct investment and a pre-IPO financing round. A full listing would have allowed SK hynix to raise outside capital without adding debt. Management believed the subsidiary's true value was not fully reflected in the parent company's market capitalization. Proceeds from a sale could have funded dividends, share buybacks, and share cancellations.

SK hynix decided against the IPO due to increased market volatility and a correction in chip stocks. The company concluded that current conditions would prevent Solidigm from achieving a valuation that matches its growth outlook. It has ended its review of both the pre-IPO financing and the listing but will continue exploring other funding methods.

The decision comes as enterprise SSD demand reaches record levels. Modern 3D NAND fabs often cost tens of billions of dollars. Outside funding could have reduced pressure on SK hynix's balance sheet. However, Solidigm holds 21.1% of the enterprise SSD market and sells exclusive products. Micron's enterprise storage division recently reported a 90% non-GAAP gross margin, suggesting Solidigm may achieve similar profitability.

SK hynix may fund the US expansion using internal cash and debt while retaining full ownership. This approach avoids selling a stake in a profitable unit at a valuation the company considers too low. The firm will keep evaluating funding options as it moves forward with the new American build.
