SK Hynix Explores $3 Billion Stake Sale in Chongqing Plant as It Pivots to AI Memory

What the Chongqing Plant Does

The Chongqing facility is a back-end semiconductor packaging and testing plant focused on NAND flash memory products . It handles downstream assembly, packaging, and testing — not front-end wafer fabrication. SK Hynix operates its front-end DRAM fabs in Wuxi and NAND fabs in Dalian (acquired via Intel's NAND business), while Chongqing serves as the finishing hub for general-purpose NAND . The plant is SK Hynix's largest overseas packaging base, established in 2014 .

Why SK Hynix Is Considering a Sale

Three main factors are driving the exploration of a stake sale:

1. AI-Focused Strategic Pivot

SK Hynix is redirecting capital toward high-margin HBM chips, its key product for Nvidia. The company announced a massive KRW 54 trillion (≈$38 billion) investment in new DRAM and HBM fabs in Yongin and Cheongju, South Korea . The Chongqing plant handles legacy general-purpose NAND packaging, which carries lower margins and does not align with the AI memory growth strategy .

2. US-China Export Control Pressure

The plant has lost US equipment waivers under tightening semiconductor export controls, making it harder to upgrade or maintain advanced equipment at the China site . This adds operational and regulatory risk, and makes continued investment in Chongqing less attractive.

3. Cost Efficiency Restructuring

SK Hynix is reorganizing its global production system, prioritizing cost efficiency in general-purpose back-end operations and considering shifting some of that footprint outside China or to partners . The company is increasing operational efficiency in back-end processes for general-purpose memory while focusing investments on advanced packaging technologies like HBM .

Valuation and Deal Structure

Reports citing Bloomberg sources value the facility at approximately US$3 billion (about KRW 4 trillion) for a potential stake sale . SK Hynix is considering bringing in external investors or selling an ownership stake, rather than an outright full exit. Potential buyers include Chinese investment funds and local semiconductor companies . The company may retain a minority stake in the plant even if a transaction proceeds .

Strategic and Market Challenges

A potential deal faces several significant hurdles:

Valuation Gap with Buyers

Chinese funds and local semiconductor firms are seen as likely bidders, but analysts warn that geopolitical risks and the facility's focus on low-margin NAND packaging could make it difficult to achieve the ~$3 billion price tag . Buyers may push for a lower valuation.

Regulatory and CFIUS-Style Hurdles

Any deal involving a Chinese buyer for a foreign-owned semiconductor asset with US-linked technology faces potential scrutiny from both US and South Korean authorities, especially given the export control environment . This could complicate or delay any transaction.

Uncertainty Over Scope

SK Hynix has publicly stated that it is "reviewing various measures to strengthen competitiveness" but that no decision has been made and nothing is finalized . The company pushed back against media reports suggesting an imminent sale, telling the Korea Exchange it is only exploring options . SK Hynix said it will provide additional disclosure either when concrete details are confirmed or within one month of its August 10, 2026 filing .

Not a Full China Exit

Analysts note that SK Hynix maintains significant front-end DRAM and NAND capacity in Wuxi and Dalian, and China still accounts for about 30–35% of its DRAM capacity and 35–40% of its NAND capacity in 2026, according to TrendForce . The Chongqing review is part of a targeted production reset, not a wholesale withdrawal from China .
