Semiconductor Strategy: SK hynix Scraps Solidigm Listing to Self-Fund U.S. Plant

SK hynix announced early Friday, October 23, that it will no longer pursue an initial public offering for its U.S.-based enterprise solid-state drive unit, Solidigm. The company cited unfavorable stock market conditions and a recent decline in semiconductor share prices as the primary reasons for the decision.

The move halts a review process that included both a pre-IPO financing round and a full public listing. Management stated that current market volatility would prevent Solidigm from achieving a valuation that fairly reflects its growth outlook. The company confirmed it will continue exploring other funding methods, though the specific timeline for the new facility remains undefined.

SK hynix maintains its plan to construct a new fabrication plant for Solidigm in the United States. The facility aims to meet rising demand for high-capacity data center drives used in artificial intelligence infrastructure. The company has not disclosed the plant's size, total cost, or expected start date for construction.

Solidigm produces high-capacity SSDs using floating gate 3D QLC NAND memory. The unit, along with its parent company, holds a 21.1% share of the enterprise SSD market. Demand for this technology is currently at a record level and is expected to grow over the next two to three years.

The decision to self-fund the expansion may be driven by Solidigm's high profitability. Micron, a competitor, recently reported a non-GAAP gross margin of 90% for its enterprise storage division. Analysts suggest Solidigm may earn similar or higher margins due to its exclusive products. These profits could generate substantial cash flow for the parent company.

Building a modern 3D NAND fab typically costs tens of billions of dollars. By retaining full ownership of Solidigm, SK hynix avoids diluting its equity and keeps control over a highly profitable asset. The company can now fund the U.S. expansion using a mix of internal cash and debt, without relying on external capital markets.
