Shares of Kioxia Holdings surged to ¥94,720 on June 16, extending a breathtaking rally that has seen the stock climb 34% in just five trading days as AI-driven memory demand reshapes global semiconductor economics. The company's market capitalization recently hit ¥44 trillion ($275 billion), with its stock price soaring 56-fold in the 18 months since its December 2024 Tokyo listing — a rise that has left even bullish analysts scrambling to catch up.
Record Profits Fueled by AI Storage Hunger
Kioxia's fiscal year ended March 2026 delivered net profit surging 103.6% year-on-year to ¥554.4 billion (roughly $3.5 billion), driven by SSD and storage demand from generative AI.
Revenue hit ¥2.34 trillion, up 37% from the prior year. But the real shock was forward guidance: Kioxia said it expects operating profit for the April–June quarter alone to reach ¥1.3 trillion ($8.2 billion) — a single quarter rivaling what most chip firms earn in a full year. That kind of trajectory is what pushed Goldman Sachs to nearly double its price target from ¥48,000 to ¥93,000 and upgrade to Buy.
A Structural Shortage Is Doing the Heavy Lifting The stock isn't rising on hype alone. Industry data shows NAND demand in 2026 growing 20–22% year-on-year while supply rises only 15–17%, widening the gap.
New fab capacity from major producers won't reach volume production until 2027 at the earliest.
TrendForce expects sharp contract-price increases in Q2 2026, while Omdia says supply relief is unlikely until well into 2027. For Kioxia, tighter supply means stronger pricing power — the ability to charge more per chip — which flows directly to the bottom line.
Valuation Looks Cheap, but the Memory Cycle Cuts Both Ways
Despite the stock's rapid ascent, analysts note Kioxia's price-to-earnings ratio remains below 10, suggesting investors still anticipate further earnings growth.
Several analysts have reportedly raised targets above ¥100,000. Yet memory chips are notoriously cyclical — prices can crash as fast as they climb. The aggressive capacity buildout of Chinese NAND manufacturers could contribute to oversupply, eroding prices. And Morningstar pegs the stock at a 764% premium to its fair-value estimate , a stark reminder that the market is pricing in perfection.
The Bigger Question: Can Storage Stay as Hot as Compute? AI's hunger for data storage — not just processing power — is the thesis underpinning this rally. Data centers now consume an estimated 70% of all memory chips produced worldwide. If that demand plateaus, Kioxia's earnings could reverse as violently as they expanded. For now, the shortage is real, the profits are record-setting, and the stock is priced as if this cycle never ends.
