SK hynix scraps Solidigm IPO

SK hynix ended its review of an initial public offering for Solidigm, its U.S. storage subsidiary, on Friday, October 23. The company stated that unfavorable stock market conditions and recent trends in semiconductor share prices made a listing unattractive. Despite canceling the stock sale, SK hynix confirmed it will still build a new manufacturing facility in the United States for Solidigm.

The new plant aims to meet rising demand for enterprise solid-state drives. SK hynix has not yet disclosed the facility's size, total cost, or construction timeline. The decision to self-fund the project leaves the expansion dependent on the company's internal resources rather than outside capital. This shift removes a potential avenue for shareholders to gain direct exposure to Solidigm's growth.

Solidigm specializes in high-capacity data center SSDs built on floating gate 3D QLC NAND memory. Demand for this technology is climbing as artificial intelligence infrastructure rollouts accelerate. The company's current manufacturing capacity is barely sufficient to cover its projected needs. A new American plant would also expand SK hynix's physical manufacturing presence in the U.S., aligning with the current push toward domestic production.

SK hynix previously considered direct investment, a pre-IPO funding round, and a full listing to pay for the expansion. An offering would have allowed the company to bring in outside capital without adding debt. It could also have established a market valuation for the subsidiary that SK hynix believes is not properly reflected in its own market capitalization. Proceeds from such a sale might have gone toward dividends, share buybacks, or share cancellations.

The company cited greater market volatility and an ongoing correction in chip stocks as the primary reasons for the reversal. In its view, present conditions would prevent Solidigm from earning a valuation that fairly reflects its growth outlook. The firm has ended its review of both a pre-IPO financing round and a listing but will continue looking at other ways to fund the project.

Micron's enterprise storage division recently reported a non-GAAP gross margin of 90%. Solidigm holds 21.1% of the enterprise SSD market alongside its parent. If similar margins persist for the next two or three years, the unit could significantly lift SK hynix's consolidated profits. This strong profitability may allow SK hynix to fund the U.S. expansion through a mix of internal cash and debt without giving up ownership.

Enterprise SSD demand is currently at a record level and is expected to rise further over the next couple of years. A modern 3D NAND fab can cost tens of billions of dollars. Outside funding could have eased the strain on SK hynix's balance sheet and left capital free for other projects. The company now proceeds with the U.S. build using its own financial resources.
