Kioxia announced plans to build its third wafer fab in Japan, partnering with SanDisk to expand NAND flash memory production.

Kioxia Holdings announced the construction of its third wafer fab in Iwate Prefecture, Japan, in partnership with manufacturing partner SanDisk to expand NAND flash memory production capacity in order to meet the surge in storage demand driven by artificial intelligence.

According to a Bloomberg report on August 27, sources familiar with the matter revealed that the new factory will be located at Kioxia's existing manufacturing base in Iwate Prefecture, primarily producing the latest generation of high-density 3D NAND flash chips designed to handle the massive data workloads generated by AI services . Kioxia plans to officially announce this expansion plan later today, and Kioxia CEO Hiroo Ota and SanDisk CEO David Goeckeler will jointly meet with Japanese Prime Minister Sanae Takaichi on the same day. Following the announcement, Kioxia's stock price rose by as much as 6.9% during trading.

This capacity expansion reflects the real pressure of a tight global memory chip supply. Memory and storage prices continue to rise globally, impacting profit margins across multiple industries, from Nvidia to automakers and mobile device manufacturers. Nvidia executives also warned of supply bottlenecks and profit margin pressures during the earnings briefing. Furthermore, Kioxia and SanDisk will apply for subsidies from the Japanese government for this project.

AI demand is driving up demand for increased production capacity, leading to a surge in global storage prices.

The global memory chip market is facing a structural supply-demand imbalance. As the core carrier of AI infrastructure, data centers are experiencing a continuous expansion in their demand for memory and storage. Large technology companies such as Google and Meta are signing multi-year contracts to secure the storage resources needed for their data centers, triggering a wave of massive capital expenditures.

Kioxia's South Korean competitors, Samsung Electronics and SK Hynix, have both announced large-scale capacity expansion plans. Kioxia's follow-up move is interpreted by the market as its proactive positioning in the high-end memory market.

The new plant in Iwate Prefecture will focus on producing high-end NAND chips for data centers. Kioxia's other major manufacturing base in Yokkaichi, Mie Prefecture, will continue to focus on chips used in consumer electronics such as smartphones, creating a differentiated division of labor between the two bases.

Long-term contracts lock in demand, and strong financial resources support investment.

Market analysts are positive about the expansion. Kazuyoshi Saito, senior analyst at Cosmo Securities, said that Kioxia's move likely indicates that it has already secured favorable long-term contracts with customers, guaranteeing future growth, "which is an extremely positive sign."

In a report, Citigroup analyst Takero Fujiwara noted that Kioxia's cash reserves are fully capable of supporting multi-billion dollar capital expenditures. He believes this investment decision signifies that the company has secured long-term contracts covering at least 2028, indicating high demand visibility. " While the company has historically been cautious with capital expenditures, we believe it has demonstrated a willingness to invest aggressively when necessary. "

Kioxia just started shipping its stacked 10th generation BiCS flash memory chips last month, and the construction of new production capacity will further strengthen its competitive position in the high-end storage market.

It is worth noting that despite the news of capacity expansion boosting its stock price, Kioxia still faces dual pressures from market competition and cyclical risks.

Meanwhile, market concerns that Kioxia might invest heavily during peak demand and subsequently face oversupply have continued to weigh on its stock price – Kioxia's stock price has fallen by about 50% since its June high.

Analysts believe that whether this capacity expansion can truly translate into long-term value largely depends on the sustainability of AI storage demand and whether Kioxia can secure a stable customer base through long-term contracts.

Japanese government subsidies accelerate the revival of the semiconductor industry.

Kioxia and SanDisk will apply for subsidies from the Japanese government for their new plant in Iwate Prefecture, continuing the policy of Japan's strong support for domestic semiconductor manufacturing in recent years.

Japan has provided substantial financial support to chip companies with factories within its borders, benefiting companies including TSMC, Sony Group, and Micron Technology. The Japanese government's strategic aim is to revitalize its domestic semiconductor industry and regain its former leading position in the global chip landscape.

If Kioxia receives government subsidies for this expansion, it will further reduce investment costs and strengthen Japan's strategic position as a major global memory chip production base.
