SK Hynix Inc (KS:000660) said on Thursday that it has commenced shipping samples of its advanced high bandwidth memory, delivering 12-high HBM4E units to major customers. The move was met positively by investors, sending the company's shares to a new record high.
Shares of SK Hynix climbed nearly 5% to a peak of 2,642,000 won, contributing noticeably to the KOSPI index, which rose by 0.7% on the session. Company officials indicated they will work closely with customers to move from sampling to mass production, a step they framed as important given elevated demand coming from the artificial intelligence industry.
HBM is an essential memory component for AI processors, and HBM4E represents the most advanced iteration currently in the industry. SK Hynix is among a limited set of companies able to produce HBM at scale - a group that includes Samsung Electronics Co Ltd (KS:005930) and Micron Technology Inc (NASDAQ:MU).
In a related commercial move, SK Hynix recently signed an agreement to supply memory chips to NVIDIA Corporation (NASDAQ:NVDA) for the latter's most advanced AI processors, reinforcing the company's role in the AI hardware supply chain.
What the announcement means
- SK Hynix has moved from development to sample deliveries for its 12-high HBM4E product, signaling progress toward commercialization.
- The share-price reaction reflects investor confidence in SK Hynix's positioning within the high-end memory market and the near-term revenue potential from AI-related demand.
- The company plans further collaboration with customers to scale to mass production, acknowledging the need for alignment before broad commercial supply.
Market context and positioning
The company emphasized its role as one of the few mass producers of advanced HBM technology. With HBM4E targeted at AI processors, the product sits squarely at the intersection of semiconductor supply chains and the AI hardware market. The recent supply agreement with NVIDIA underscores customer uptake among AI platform providers.
Investor takeaways
- SK Hynix's sample shipments of HBM4E mark a tangible step toward commercial production for a high-end product used in AI processors.
- Share-price strength following the announcement suggests market optimism about demand and SK Hynix's execution prospects.
