The takeaway: SK Hynix says it has yet to build a U.S. semiconductor factory for Solidigm as rising demand for AI memory strains the subsidiary’s production capacity. But a possible initial public offering that could have helped finance the expansion has been put on hold. The decision shows how the need to expand chip production can conflict with the financial conditions required for financing.
A new facility would support Solidigm’s high-capacity enterprise SSD business. The existing production capacities barely cover the forecast demand, so additional production is a priority for the parent company SK hynix.
Due to the cancellation of the IPO, the expansion plans remain in place, but the financing remains unclear. SK Hynix has stopped exploring both an initial public offering and a pre-IPO funding round, citing market volatility and a correction in semiconductor stocks. The company says it will continue to explore other financing options.
Solidigm plans to expand production of floating gate 3D QLC NAND memory for its high-performance data center SSDs. QLC stores four bits per memory cell, while the three-dimensional architecture stacks cells to increase storage density. Solidigm uses both technologies in enterprise storage drives.
The increasing use of AI infrastructures is increasing the demand for high-capacity storage and straining production. To keep up, Solidigm needs to expand its production capacity, not just expand its product range.
A new US factory would increase production to support this growth and expand SK Hynix’s American manufacturing footprint. SK Hynix has not said when the factory will open or how much it will produce. The scope of the project also remains unclear. Building a modern 3D NAND factory can cost tens of billions of dollars.
SK Hynix considered direct investment, pre-IPO financing and a public offering to finance additional capacity. An IPO would have raised outside capital without additional debt and given Solidigm a separate market valuation from the parent company. SK hynix believes that the share price does not fully reflect Solidigm’s value, but weak market conditions would result in the subsidiary being undervalued.
SK Hynix hasn’t said how it will pay the factory. It could use internally generated cash, loans, or a combination of both. Solidigm and SK hynix together hold 21.1% of the booming enterprise SSD market. However, their combined share does not reveal Solidigm’s profitability as a sole proprietorship or how much money it could contribute to building the factory.
