Reports emerged that SK Hynix plans to upgrade its Dalian, China factory to produce NAND flash memory chips stacked 240 layers or more — a move aimed squarely at fending off fast-rising Chinese competitors and capturing surging AI-driven demand. Shares on Frankfurt's exchange traded at €866.00, up 0.9% on the session but still down roughly 12% from just a week earlier, raising the question of whether this investment can stabilize a stock that has been under pressure. SK Hynix Plans a Dalian NAND Upgrade — but Is It Playing Catch-Up in China or Building a Launchpad for Solidigm's IPO?
Shares of SK Hynix edged up 0.9% to €866.00 on Frankfurt's exchange, adding to a broader chip-sector bounce after strong Super Micro results calmed nerves about AI server demand. But the company's own catalyst was more specific: SK Hynix confirmed it has been installing equipment at its Dalian, China factory to produce NAND chips with 240 layers or more, up from the 192 layers it manufactures there today.
• China's Homegrown Rival Is Already Winning the Local Market. The upgrade is defensive as much as ambitious. China's YMTC captured 38.5% of China's NAND market in Q2 2026, overtaking Samsung's 33.5% and leaving SK Hynix at just 17%.
YMTC held roughly 28% for full-year 2025 — meaning it gained more than ten points in months. More layers per chip means more storage density and lower costs , so staying on older technology in China is a recipe for further share loss.
• The Solidigm IPO Rides on This Factory. Solidigm — the U.S.-based NAND unit SK Hynix created from its 2021 acquisition of Intel's flash business — manufactures all its NAND at Dalian, and is preparing for an IPO potentially valued at up to $150 billion, with Goldman Sachs and Morgan Stanley as lead banks.
If Washington revokes or restricts equipment licenses for Dalian, Solidigm's entire manufacturing base becomes legally precarious — a risk that prospective IPO investors will price carefully.
• Washington Holds the Key, and the Door Isn't Fully Open. The U.S. Bureau of Industry and Security previously said it "would not permit capacity expansions and technology upgrades" at these plants, but has since granted both SK Hynix and Samsung annual licenses covering 2026 for chipmaking equipment shipments.
SK Hynix is authorized to make chips up to 240 layers and may seek permission to research 300-plus-layer chips at Dalian — work that could also support a planned new U.S. NAND factory.
• The Stock's Rebound Has a Long Way to Go. Despite this week's gains, shares have dropped roughly 12% from €988 just nine days ago. No binding production start date and no defined earnings contribution can be derived from the Dalian report.
Q3 results arrive October 28 , giving investors a hard data point within days. Until then, the Dalian upgrade signals strategic intent — not yet delivered profit.
