Kioxia

Kioxia and SanDisk today announced extensive plans for expanding their flash memory production in Japan. The two partners intend to invest around five trillion yen (approximately 31 billion US dollars) by 2032. The company is thus responding to the massively increasing demand for NAND memory chips, which is primarily driven by applications in artificial intelligence (AI) and modern data centers. The focus is on expanding the sites in Yokkaichi and Kitakami, with implementation partly dependent on government support from Japan. As part of the cooperation, Kioxia bears 60 percent of the investment sum, while SanDisk takes over the remaining 40 percent.

A central component of the project is the construction of the so-called K3 factory, whose production start is planned for fiscal year 2029. 8 trillion yen is allocated for this complex alone.

Kioxia thus signals its ability to expand, which should strengthen its negotiating position in long-term supply contracts with large cloud providers. The goal of the capacity expansion is an increase in monthly production from the current 350,000 to up to 550,000 wafers.

The investment offensive comes during a phase of intensified competition. In the second quarter of 2026, Chinese competitor YMTC succeeded for the first time in overtaking Kioxia in terms of shipment volume and securing third place in the global NAND market. YMTC also plans an IPO in the fourth quarter of 2026 and aims for market leadership by the end of 2027. In parallel, SK Hynix CEO Kwak Noh-jung today warned of a persistent shortage of memory chips that could last until 2030. SK Hynix is closely connected with Kioxia through shareholdings and is also considering an IPO for its subsidiary Solidigm.

The industry is responding to the transformation towards custom AI chips with these measures. 15 billion euros. Despite the ambitious expansion course, the stock price shows short-term weakness and is trading 24 percent below its 50-day average. Nevertheless, the long-term performance remains remarkable, as the value has shown a gain of 360 percent since the beginning of the year.
