SK hynix cancels Solidigm IPO to self-fund new U.S. plant

SK hynix will build a new fabrication plant in the United States for its enterprise solid-state drive business using its own capital. The company announced on Friday, October 23, that it is abandoning plans to take its U.S. subsidiary, Solidigm, public. Management cited unfavorable stock market conditions and recent declines in semiconductor share prices as the primary reasons for the decision.

The move alters the funding strategy for a facility designed to meet rising demand for high-capacity data center storage. SK hynix had previously considered three paths to finance the expansion: direct investment, a pre-IPO funding round, or a full public listing. An offering would have provided outside capital without increasing debt. It might also have allowed the company to distribute proceeds to shareholders through dividends or buybacks. The company has now ended its review of both the financing round and the listing.

Solidigm specializes in floating gate 3D QLC NAND memory for enterprise drives. The subsidiary holds a 21.1% share of the global enterprise SSD market alongside its parent. Demand for these high-capacity units is climbing as artificial intelligence infrastructure expands. Current manufacturing capacity is nearly maxed out relative to expected future needs. A new American factory would increase output and strengthen SK hynix's domestic production footprint.

The company has not yet disclosed the size of the new facility, its total cost, or a construction timeline. Building a modern 3D NAND plant typically requires tens of billions of dollars in investment. This creates a significant capital strain, particularly because enterprise SSD demand is at a record high and projected to grow over the next two years.

Analysts note that the decision may reflect Solidigm's strong profitability. Micron's enterprise storage division recently reported a non-GAAP gross margin of 90%. Solidigm may achieve similar or higher margins by selling exclusive products. If these profit levels hold for the next two or three years, the subsidiary could generate substantial cash flow. This would allow SK hynix to fund the expansion through a mix of internal cash and debt while retaining full ownership.

The parent company stated that current market volatility prevents Solidigm from earning a valuation that fairly reflects its growth outlook. By keeping the subsidiary private, SK hynix avoids selling a stake at a price it considers too low. The company will continue to evaluate other methods to fund the project, though it has not specified which alternatives remain under consideration.
