Shares of SKHX, a 2x daily leveraged ETF tracking SK Hynix, plunged 7.2% to $16.92 after reports surfaced that the South Korean memory giant is weighing a U.S. IPO for Solidigm, its NAND flash storage subsidiary. The news rattled investors less for what it revealed about Solidigm and more for what it implied about the parent company's tangled corporate structure. SK Hynix's Solidigm IPO Plan Rattles Investors — Is Carving Out a Crown Jewel a Smart Play or a Governance Red Flag?

Shares of SKHX, a 2x leveraged ETF tied to SK Hynix, tumbled 7.2% to $16.92 Monday after reports that SK Hynix is preparing to list its U.S. data-storage subsidiary Solidigm on American exchanges as early as 2027. The move could create the largest semiconductor IPO in history — but investors are punishing the stock over fears it may dilute their claim on a key growth asset.

• A $9 Billion Acquisition Could Now Float at Up to $150 Billion SK Hynix created Solidigm in 2021 after acquiring Intel's NAND flash storage and SSD business for about $9 billion.

Reuters reported the subsidiary could now be valued at up to $150 billion, with Solidigm holding pitch meetings this week with investment banks competing for IPO roles.

The company could raise $15 billion in the offering. That's a staggering return on paper — but SK Hynix shareholders won't fully benefit if the parent sells down its stake.

• The "Grandchild Company" Problem Worries Governance Watchdogs SK Group's semiconductor ownership runs from SK Inc. → SK Square → SK Hynix → AI Company → Solidigm — a five-layer chain. The Korea Corporate Governance Forum, a nonprofit of investment professionals, urged SK Hynix in August to drop the plan entirely, arguing that an IPO would deepen the group's pyramid ownership structure. In plain terms: profits from the booming AI storage business could flow to new Solidigm shareholders instead of trickling back up to SK Hynix holders.

• Selling a Piece of the AI Storage Boom Carries Real Cost Solidigm gives SK Hynix exposure to enterprise SSDs and data-center storage, complementing its strength in DRAM and high-bandwidth memory.

If a portion of profits from the NAND business flows to Solidigm investors as dividends, the economic share that SK Hynix shareholders indirectly enjoy could shrink. For SKHX holders, who get twice the daily move, that earnings dilution risk hits doubly hard.

• Nothing Is Final, but the Process Is Already Underway The plans remain at an early stage and could change depending on market conditions. Still, former SK Hynix president Roh Jong-won has already set up a U.S. private equity firm to invest in a future Solidigm IPO, and institutional investors including UAE sovereign wealth fund Mubadala are reportedly interested through Goldman Sachs. That suggests momentum is building beyond mere speculation. The news lands less than three months after SK Hynix itself began trading on Nasdaq at $149, with shares subsequently hitting a post-listing record of $198.63. The question now: will spinning off Solidigm unlock value — or export it?
