Solidigm, the NAND flash subsidiary of South Korean chipmaker SK hynix, is considering a U.S. listing and has met with several investment banks regarding underwriting, investment banking sources revealed on Sunday. Market observers anticipate Solidigm's valuation could reach $150 billion, with a potential fundraising target of $15 billion. This move has sparked debate among investors over whether it will unlock hidden value or dilute existing shareholder equity.
