Samsung Stock Surges as Chipmaker Beats Micron in HBM4 Race

TLDR

• Samsung Electronics stock climbed 4.9% to 6.4% after announcing mass production of HBM4 memory chips starting this month.
• The Korean chipmaker will supply HBM4 chips to Nvidia by mid-February for Vera Rubin AI accelerators.
• Samsung’s production timeline puts it ahead of Micron Technology, which plans HBM4 rollout in Q2 2026.
• Micron stock still rose 3.08% as analysts expect the company to hold its 20%-25% HBM market share.
• AI chip makers are adopting three-supplier strategies, creating space for Samsung, SK Hynix, and Micron.

Samsung Electronics shares popped on Monday following reports that the company will kick off mass production of next-generation memory chips this month. The stock gained between 4.9% and 6.4% depending on the source.

Samsung Electronics Co., Ltd. (005930.KS)

Industry insiders told South Korea’s Yonhap news agency that Samsung will begin producing HBM4 chips in late February. These high-bandwidth memory chips are critical components for artificial intelligence processors.

The company plans to ship these advanced semiconductors to Nvidia by mid-February. The chips will power Nvidia’s upcoming Vera Rubin AI accelerators, which represents a key win for Samsung in the AI supply chain race.

Nvidia stock jumped 7.87% on the news. SK Hynix, another South Korean memory chip manufacturer, saw shares rise 5.72%.

Race Against Micron Intensifies

Samsung’s announcement puts it in direct competition with Micron Technology for AI chip market share. Micron has seen its stock more than quadruple over the past year thanks to HBM chip demand.

Micron shares rose 3.08% despite the competitive pressure. The company plans to ramp up its own HBM4 production during the second quarter of 2026.

That timeline puts Micron roughly one quarter behind Samsung’s production schedule. Micron CEO Sanjay Mehrotra outlined the company’s HBM4 plans during the most recent earnings call.

Samsung’s stock has nearly tripled in the past 12 months. The memory chip boom has lifted valuations across the entire sector.

Wall Street Sees Room for Multiple Winners

Analysts aren’t overly concerned about market share battles between the three major HBM suppliers. Demand remains strong enough to support all players.

UBS analyst Timothy Arcuri noted that AI accelerator vendors are moving toward three-supplier sourcing strategies. Companies previously relied on just two suppliers for their HBM needs.

This shift benefits Micron. Analysts estimate the company can maintain the 20%-25% market share it captured last year despite increased competition.

HBM chips command higher profit margins than standard memory components. The lucrative margins make the market attractive for Samsung, Micron, and SK Hynix.

Financial Position Remains Strong

Samsung’s market capitalization sits at $694.62 billion. The company reported revenue of $223.32 billion with a 7% growth rate over three years.

The chipmaker maintains a current ratio of 2.63 and a debt-to-equity ratio of 0.04. These metrics indicate solid liquidity and low leverage.

Samsung’s gross margin stands at 36.65% with an operating margin of 9.51%. The Altman Z-Score of 7.78 suggests strong financial health.

The company’s P/E ratio of 32.73 sits near its one-year high. Technical indicators show an RSI of 100, suggesting the stock may be overbought.

Samsung didn’t immediately respond to requests for comment. The company’s HBM4 production represents a major milestone in the ongoing AI chip race.
