Kioxia Slips as Memory Sector Jitters Overshadow Applied Materials Alliance
Published on 10/07/2026 at 14:13 | Editorial boerse-global.de
Kioxia shares fell 4.2% to EUR 99.71 on Thursday, extending a pullback that began the previous session when the stock closed at EUR 104.06. The decline is not tied to any company-specific disclosure; instead, it reflects a broad wave of weakness sweeping across the memory technology segment.
At the heart of the selling pressure are reports that Toshiba plans to roughly double its nearline hard disk drive capacity by fiscal 2027. The prospect of future oversupply — and the persistent pricing pressure that would accompany it — weighed on several memory manufacturers. Sentiment in the NAND space has also cooled, with concerns mounting over a potential slowdown in artificial intelligence investment and the steady capacity expansion by Chinese NAND producers.
Tokyo's Chip Names Retreat in Tandem
The trend was visible in Kioxia's home market, where semiconductor and AI-related stocks retreated across the board even as leading US indices pushed higher. Japanese market reports noted that six of seven tracked semiconductor and AI names lost ground. Kioxia was unable to sidestep the downdraft affecting its domestic peers.
The setback did not emerge from a vacuum. Memory has historically been a cyclical business, and when doubts surface about cooling enterprise storage demand or the long-term margin impact of Chinese competition, investors are quick to hit the brakes. Those doubts carry extra weight for a stock that has still posted a staggering 448% gain since the start of the year. At such elevated valuations, any minor crack in the sector backdrop invites profit-taking — a correction of overheated expectations rather than a structural break in the growth story, by most accounts.
Should investors sell immediately? Or is it worth buying Kioxia?
Strategic Bets on Next-Generation Memory
Away from the market-wide swings, Kioxia is pressing ahead with strategic work on future technology generations. On September 29, Applied Materials and Kioxia announced an innovation partnership at Applied Materials' EPIC Center in Silicon Valley. The joint research and development effort targets advanced memory structures, multi-chip stacking, and new material solutions for memory chips in the AI era.
The move underscores that Kioxia is investing precisely where future margins will be generated. While standard NAND capacity from China may pressure pricing in the volume business, leadership in complex chip architectures cannot be replicated overnight.
On the operational front, subsidiary Kioxia Iwate secured platinum status in a Responsible Business Alliance audit on October 1.
Earnings Will Put the Thesis to the Test
Hard data on the actual business trajectory is due soon. Kioxia Holdings has scheduled the release of its financial results for the second quarter of fiscal 2026 for October 30 at 18:45 Japan time.
Those figures should shed light on how the current pricing environment and memory demand are flowing through the company's books. Until then, nervousness is likely to persist. For investors watching the company, tolerance for cyclical swings remains essential — the fundamental positioning in high technology still holds.
