"A buyback could send a signal that management views the stock as oversold," said Ikuo Mitsui, a fund manager at Aizawa Securities, capturing the mood as Kioxia's shares plunged. Since hitting a peak of ¥112,700 on June 22, the Japanese memory chipmaker’s stock has plunged 65%, wiping out about $245 billion in market value. At its peak, Kioxia briefly surpassed Toyota Motor to become Japan's most valuable company, but the rapid decline reversed much of that gains.
Kioxia’s listing on the Tokyo Stock Exchange in late 2024 was followed by a surge fueled by soaring demand for NAND flash memory, especially from data centers expanding AI infrastructure. The stock skyrocketed more than 500% in 2025 alone, driven by tight supply pushing profits higher. Yet, by July, a broad selloff in AI-related equities hit Kioxia hard. Investors grew cautious amid fears of overextended positions and increased competition from Chinese NAND manufacturers ramping up capacity. This raised concerns about Kioxia’s ability to maintain pricing power, dragging down the stock along with South Korean rivals SK Hynix and Samsung, which also saw double-digit drops.
Against this backdrop, speculation is mounting that Kioxia might accelerate shareholder returns through dividends and share buybacks. At its investor day in June, the company emphasized dividends as a priority but left the door open for buybacks depending on market conditions. A spokesperson confirmed Kioxia is still evaluating buybacks but has not committed to a plan. Analysts like SK Kim from Daiwa Securities note that solid cash flow backed by long-term supply contracts and steady data center demand gives the firm room to maneuver. Enhanced shareholder returns could lure in value investors who might have been sidelined during the rally.
The situation remains fluid. As Kioxia’s stock trades significantly lower than its recent highs, any move toward buybacks or increased dividends would test whether management is confident the selloff has overshot. Investors will be watching closely for signals that the company is ready to stabilize its valuation amid a shifting memory chip landscape.
