- Jensen Huang, Nvidia’s CEO, is set to arrive in South Korea this week for meetings with Samsung, LG, and leading Korean technology firms.
- The company started delivering samples of its newest HBM4E high-bandwidth memory chips to clients, gaining ground on competitors.
- Approximately 48,000 unionized employees voted to accept a new compensation package, with 74% approval preventing a major work stoppage.
- LG Electronics shares surged to their 29.9% daily trading limit for consecutive sessions, while Naver climbed 16% on anticipated executive discussions with Huang.
Shares of Samsung Electronics (005930) reached an unprecedented closing price on Monday, soaring 10.1% as three powerful catalysts aligned simultaneously. The anticipated arrival of Nvidia’s CEO Jensen Huang in South Korea, a significant advancement in advanced memory chip technology, and the resolution of potential labor disruption combined to produce one of the company’s most impressive single-session gains in recent memory.

The rally propelled Samsung’s total market capitalization beyond the 2,000 trillion won threshold when including preferred shares — a significant benchmark that highlights the dramatic shift in how investors now value the Korean semiconductor giant within the artificial intelligence investment landscape.
Huang’s arrival in Seoul is anticipated later this week, with confirmed meetings scheduled with LG Group’s Chairman Koo Kwang-mo alongside other prominent Korean business leaders. Nvidia has also organized a “Korean Partner Night” event during the COMPUTEX technology conference in Taipei, where representatives from both Samsung and SK Hynix are expected to attend.
“Jensen’s visit to Korea has a major implication. Nvidia needs Korea,” said Jeff Kim, analyst at KB Securities.
This isn’t a ceremonial stopover. Last year, Nvidia pledged to deliver over 260,000 of its cutting-edge AI accelerators to South Korea’s government entities and major corporations, counting Samsung and Hyundai Motor Group among the recipients.
HBM4E Memory Breakthrough Shifts Competitive Landscape
On the technology front, Samsung announced it has commenced shipping the industry’s first 12-layer HBM4E sample chips to significant worldwide clients. HBM4E represents the next evolution of high-bandwidth memory technology — specialized chips positioned adjacent to sophisticated AI processors to deliver data at exceptional speeds.
This development carries weight because Samsung has lagged behind SK Hynix in the high-bandwidth memory market throughout the majority of the artificial intelligence expansion cycle. The HBM4E sample distribution announcement prompted investors to consider whether Samsung might finally be narrowing that competitive disadvantage.
“Samsung has been valued at a discount to SK Hynix due to its weaker competitiveness in HBM, but the news appears to be supporting share price gains,” said BNK Investment & Securities analyst Lee Min-hee.
Nvidia’s most powerful processing units require dependable HBM supply chains. While a CEO’s visit to a memory chip manufacturer doesn’t guarantee a contract — it clearly signals where critical supply constraints exist.
Labor Agreement Eliminates Major Uncertainty
Contributing to the cascade of positive developments, Samsung also cleared a substantial labor uncertainty that had been pressuring investor sentiment. Roughly 48,000 union members ratified a revised compensation and incentive agreement, eliminating the threat of an 18-day work stoppage. The agreement secured approximately 74% member support.
The settlement incorporates a performance-based bonus framework, allocating 10.5% of semiconductor division operating profits for special distributions to chip manufacturing employees.
For market participants, the primary concern centered less on workplace relations and more on production continuity. Samsung’s semiconductor manufacturing facilities represent critical nodes in global memory chip supply networks, and any operational disruption would have struck the company during a particularly inopportune moment.
A judicial decision had previously mitigated the risk of complete production halts by mandating minimum staffing levels at certain facilities during any potential labor action. The formal vote approval eliminated the final remaining uncertainty.
The optimistic sentiment rippled throughout South Korean technology equities. LG Electronics shares hit their 29.9% daily maximum limit for the second consecutive trading session, also achieving a new record peak. Naver shares advanced 16% following announcements that senior executives would meet with Huang on Friday.
South Korea’s semiconductor shipments abroad jumped to record levels in May, contributing to the nation’s overall export growth registering its largest increase in more than four decades.
