Kioxia Holdings stock climbed to 74,250 JPY on June 02, pushing the company’s market value past 40 trillion JPY. The rally follows the company’s announcement of wafer-bonding technology that delivers faster memory performance than Samsung’s offerings. Data center demand for AI processing is driving memory prices higher, and Goldman Sachs upgraded Kioxia to Buy with a 93,000 JPY price target.

New Technology Shifts Competition Away From Capacity

Kioxia commercialized chip-stacking technology called CBA (chip bonding architecture) ahead of Samsung and SK Hynix. The technology prioritizes speed over storage layers, addressing a fundamental shift in memory demand. AI systems require fast data access rather than maximum capacity, making Kioxia’s approach valuable for data center operators building AI infrastructure.

Goldman Sachs Raises Price Target to 93,000 JPY

Goldman Sachs upgraded Kioxia from Neutral to Buy and raised its price target from 48,000 JPY to 93,000 JPY. The upgrade reflects expectations that NAND memory will remain undersupplied through 2028. Goldman forecasts NAND average selling prices will rise 283% year-over-year in 2026 and 33% in 2027, benefiting all major memory makers but particularly those with advanced technology.

Earnings Growth Accelerates on AI Demand

Kioxia reported operating profit of 870.4 billion JPY for the year ending March 2026, up 92.7% from the prior year. Sales reached 2.34 trillion JPY, up 37% year-over-year. The company generated 616.5 billion JPY in operating cash flow, enabling 281.1 billion JPY in capital investment while reducing debt. Data center customers paid higher prices for memory as AI infrastructure buildout intensified.

At the current stock price of 74,250 JPY, Kioxia trades at a forward price-to-earnings ratio of roughly 13 times based on consensus 2027 earnings estimates of 5,700 JPY per share. Institutional investors view this valuation as attractive given the company’s 51.9% return on equity and the durability of the memory upcycle. The company plans to present its technology roadmap at an investor briefing on June 02.

Final Thoughts

Kioxia’s wafer-bonding technology and Goldman Sachs’ Buy rating with a 93,000 JPY target signal confidence in sustained memory demand through 2028. At a forward P/E of 13x, the stock offers room to run if earnings growth continues.

FAQs
