Solidigm is exploring a US initial public offering as early as next year that could value the SK Hynix subsidiary at up to $150 billion and raise as much as $15 billion. The Rancho Cordova, California-based storage company met with investment banks this week in a competitive process for IPO roles, Reuters reported, although the size and timing of a transaction remain uncertain. SK Hynix said Solidigm is reviewing options to strengthen its competitiveness but has not made formal plans. Solidigm produces NAND flash memory and enterprise solid-state drives for servers and data centers, positioning it to benefit from demand for AI-related storage. The potential listing has also renewed concerns in South Korea about overlapping listings within SK Group and the group's ownership structure.
