SK Hynix's Triple Play: HBM Lock-In, a Possible $150 Billion Solidigm Listing, and Hard Bargaining at Home

SK Hynix weighs a $150 billion Solidigm IPO, expands HBM4 output as Nvidia, Alphabet and AMD take about 85% of 2027 HBM capacity.

Three themes are converging around SK Hynix as the memory maker heads toward its next earnings report: an HBM order book increasingly dominated by a handful of American tech giants, a potential blockbuster listing of its US NAND subsidiary, and a management team driving a hard bargain on costs and labor back in South Korea.

Analysts Lift the Bar Ahead of Quarterly Results

Expectations for SK Hynix's operating profit have been revised upward in the run-up to the quarterly release. Mirae Asset analyst Park Yeon-joo pointed to faster-than-anticipated global adoption of AI applications, with worldwide semiconductor supply continuing to trail demand. The upcoming figures will nonetheless draw close scrutiny — after a strong run in the share price this year, South Korean memory manufacturers face unusually elevated market expectations. Currency effects from a temporarily firmer won have also prompted modest adjustments to revenue forecasts, though they have not derailed the sector's underlying upward trajectory.

Nvidia, Alphabet and AMD Take the Lion's Share of HBM

High Bandwidth Memory for accelerator cards remains the central growth engine. According to Morgan Stanley Research estimates, Nvidia, Alphabet and AMD together will account for roughly 85 percent of global HBM production capacity in 2027, leaving only a sliver of the worldwide market for all other buyers. Producing these memory generations consumes substantial cleanroom capacity: a single bit of HBM requires about three times the wafer capacity of standard DRAM, a factor that climbs to fourfold for upcoming generations. SK Hynix began series production and shipment of HBM4 in the second quarter of 2026 and has spent recent months negotiating long-term supply agreements with around ten core customers to ease the squeeze.

Capital Spending Scales Up at Home and Abroad

To keep pace with demand, the company is pushing forward multi-billion-dollar investment programs. In August, SK Hynix approved spending of 35.2 trillion won for a second DRAM fab in Yongin and 19.1 trillion won for NAND production in Cheongju — projects designed to expand its domestic manufacturing base substantially by the end of the decade. In North America, management is weighing additional moves. More than $4 billion has already been earmarked for an advanced packaging plant in Indiana, scheduled to process DRAM wafers shipped from South Korea starting in the second half of 2029. Reuters reports that SK Hynix is also evaluating options for wafer fabrication on US soil, including leasing cleanroom space at Intel's Ohio site or forming a joint venture. High US construction costs and the actual scale of government incentives remain open questions before any final decision.

Solidigm IPO Talk Puts a $150 Billion Tag on the NAND Unit

Funding for that expansion could come from a much larger source. According to Reuters, SK Hynix is considering a multi-billion-dollar initial public offering of its US subsidiary Solidigm, which specializes in NAND flash memory. Preliminary talks with investment banks were already held on Friday, though the company has not officially confirmed any listing plans. An offering could come as early as 2027, with discussions centering on a valuation of up to $150 billion and a capital raise of roughly $15 billion. Such a deal would free up considerable resources for SK Hynix, bolstering its financial footing for future technology projects in a fiercely competitive memory market.

Washington Talks and Seoul's Regulatory Lens

Potential US production sites are drawing attention alongside the financing considerations. SK Hynix has stated that no concrete projects have been confirmed. Roughly two weeks ago, preliminary discussions between SK Hynix and Intel about possible US memory manufacturing came to light, covering options such as leasing part of a planned Intel fab in Ohio or a joint venture with cloud providers — again with no final agreement in place. Any such move would also fall under regulatory oversight at home: South Korea's Ministry of Trade, Industry and Energy made clear that US manufacturing plans must be reviewed under the Act on Prevention of Divulgence and Protection of Industrial Technology if national core technologies are involved.

A Cost-Conscious Stance and Labor Peace at Home

Closer to home, management is keeping a tight grip on costs. On September 14, SK Hynix and Samsung Electronics jointly rejected a demand from utility KEPCO for advance payments of 25 trillion won — about $18.7 billion — to supply power to planned semiconductor clusters. Both companies cited uncertainty over long-term semiconductor demand, underscoring the cautious posture of the leading memory makers toward large-scale infrastructure commitments and their reluctance to make significant upfront financial outlays of that magnitude. Operations, meanwhile, have regained clarity after weeks of negotiation: in mid-September, the South Korean union approved a wage agreement with management that raises the cash portion of performance bonuses from 40 percent to 50 percent, with the share paid in stock reduced accordingly.
