A UBS forecast (2026-07-04) projected DDR contract prices to rise QoQ +32% in Q3 2026 (+18% in Q4) and NAND to rise +30% in Q3 (+12% in Q4) — rising memory contract prices are a variable that directly feeds into the company's average selling price (ASP). SK hynix's 2026 HBM revenue is projected at KRW 41.2 trillion with shipment volume of 19.2 billion Gb, and the share of volume destined for Nvidia is projected to decline from 72% in 2025 to 63% in 2026 (E, compiled from SK hynix Newsroom · Newdaily).

News Timeline

DateEvent
2026-06-25Recorded an intraday all-time high of KRW 2,987,000, driven by speculation of an earlier Nasdaq ADR listing schedule and continued foreign net buying (A/E mixed)
2026-07-02-14.57% (closed at KRW 2,187,000), a record single-day decline, as news of Meta's entry into the cloud business spread doubts about the memory-shortage narrative
2026-07-10Listed American Depositary Shares (SKHY) on the Nasdaq, issuing approximately 178 million ADSs (equivalent to approximately 17.8 million common shares)
2026-07-13~16Sharp swings for 4 consecutive trading days (-10.37%/-8.67%/+11.60%/-11 to -13%), with repeated breaches and recoveries of the KRW 2 million and KRW 1.7 million levels. Driven by resurfacing concerns over a slowdown in AI infrastructure investment (citing Morgan Stanley commentary)
2026-07-21 (as-of date)+1.68% (authoritative figure), driven by strong semiconductor exports (semiconductor exports for July 1-20 up +180.6% YoY) and a rebound in the Philadelphia Semiconductor Index

Reports indicate that the July share price swings stemmed not from confirmed Q2 results (scheduled for release on July 29) but from repeated overlapping sentiment and supply/demand factors — supply pressure from the new Nasdaq ADR issuance, shifting overseas narratives around the continuation or slowdown of AI infrastructure investment, and geopolitical and interest-rate concerns (Herald Economy · Daum News, compiled).

Risk Factors

  • US-China export controls: As of 2025, approximately 68.8% of revenue passed through US-based sales subsidiaries and 19.7% through China-based ones; starting in 2026, VEU (Verified End User) benefits were revoked, requiring case-by-case individual approval for equipment imports to the Wuxi and Dalian plants in China (Korea Economic Daily, 2026-06-25).
  • Intensifying HBM market competition: From 2026, the HBM4 market shifts to a three-way competition among SK hynix, Samsung Electronics, and Micron, and HBM market share fell from 69% a year earlier to 56-58% in Q1 2026 (A/E mixed).
  • Cyclicality of the memory semiconductor industry: SK hynix has a precedent of a downcycle, having posted an operating loss of KRW 7.7303 trillion in 2023 (A).
  • US export controls restrict the import of the latest EUV equipment to China-based plants, which may constrain process node shrinkage and productivity gains (Korea Economic Daily, 2026-06-25).
  • Details related to the Yongin semiconductor cluster were not confirmed in research and remain unconfirmed.
