SK Hynix Weighs Stake Sale of Chongqing Packaging Plant Amid AI-Memory Push

Core Development: Potential $3 Billion Stake Sale
South Korean memory-chip maker SK Hynix is reviewing options for its semiconductor packaging and testing facility in Chongqing, China. Bloomberg and multiple Korean and Chinese sources say the company is in early talks with advisers about a possible stake sale valued at roughly $3 billion (about 4 trillion won). Potential buyers include Chinese investment funds and domestic semiconductor firms. SK Hynix may retain a minority interest, but no final decision has been made.
Background & Context: From Front-End Expansion to Back-End Divestiture
SK Hynix operates three major fabs in China: a DRAM wafer plant in Wuxi, a NAND flash wafer plant in Dalian, and the Chongqing back-end hub that handles packaging and testing of NAND products. The Chongqing plant began mass production in July 2014 and has been a key outlet for the company’s NAND flash output. Analysts view the contemplated sale as part of a strategic pivot toward higher-margin AI-focused memory products—particularly high-bandwidth memory (HBM)—and away from lower-margin back-end operations.
Timeline
- July 29, 2026 – SK Hynix reports record Q2 results; shares fall 9.6 % despite strong earnings.
- August 4, 2026 – Bank of America resumes coverage with a “Buy” rating, citing HBM leadership.
- August 7, 2026 – ADRs close at $143.54 after earlier volatility.
- August 10, 2026 – SK Hynix tells the Korea Exchange it is “reviewing options” for its packaging business.
- July 30, 2026 – Chairman Chey Tae-won purchases roughly 4.79 billion KRW of shares.
- September 10, 2026 – Deadline to submit a binding follow-up statement to the Korea Exchange regarding the Chongqing stake.
Data & Statistics
- Valuation: Potential stake sale estimated at $3 billion (? 4 trillion won).
- Capacity Share: About 30–35 % of SK Hynix’s DRAM and 35–40 % of its NAND capacity are located in China.
- Capex: A 54 trillion won (? $38 billion) domestic expansion plan includes a new DRAM fab (Yongin Y2) slated for construction in July 2027 and a NAND fab (Cheongju M17) breaking ground in February 2027.
- Financials: Q2 2026 revenue of 79.32 trillion won, operating profit of 60.54 trillion won, net income of 93.92 trillion won (inflated by a one-off Kioxia stake sale).
Why It Matters: Capital Reallocation and Geopolitical Risk
Divesting the Chongqing back-end asset would free capital for SK Hynix’s AI-memory expansion and reduce exposure to U.S. export controls that limit advanced semiconductor sales to China. The move could, however, affect cost efficiencies in legacy NAND production and draw regulatory attention from Beijing.
Official Statements & Responses
The company has not confirmed any specific transaction structure or timeline beyond the September 10 filing deadline.
Conflicting Reports & Gaps
All sources agree on the approximate $3 billion valuation, but details differ on the transaction structure. Some reports suggest a majority-stake sale with a retained minority interest; others mention only a partial stake sale. No source provides a definitive closing timeline, and the September 10 deadline relates solely to the required exchange statement.
What’s Next: Boardroom Decision and Expansion Rollout
The September 10 deadline will determine whether a sale proceeds, is postponed, or abandoned, influencing investor sentiment and funding for domestic AI-memory fabs. Construction of the Yongin Y2 DRAM fab and the Cheongju M17 NAND fab is scheduled to begin in mid-2027, with cleanrooms expected by mid-2029 and the end of 2028, respectively. These projects are central to SK Hynix’s strategy to strengthen its position in the HBM market.
