Japanese memory chip maker Kioxia Holdings has seen its market value fall to roughly one-third of the peak it reached about four months ago, according to Nikkei Asia. The NAND flash specialist briefly became Japan's most valuable listed company at its June peak, a milestone that now looks increasingly distant.
Two forces are behind the slide. Rising interest rates are threatening the business model of the data centers that buy Kioxia's memory, while Chinese NAND competitors are closing the gap. The company's April-September earnings, due out Oct. 30, are still expected to show a historic profit gain, setting up a sharp contrast between past results and future risk.
Why Kioxia's Market Value Is Falling
Kioxia's fortunes are tied closely to the data center boom that has driven demand for NAND flash memory used in servers and AI infrastructure. That boom has been financed partly by debt, and as borrowing costs rise, the economics of building and operating large data centers come under pressure.
At the same time, Chinese memory makers are emerging as serious rivals in NAND flash. Their advance threatens to erode the pricing power that has supported Kioxia and its peers during the recent memory upcycle.
- Kioxia's market value has dropped to about one-third of its June peak, per Nikkei Asia.
- The company had become Japan's most valuable listed company at that peak.
- Rising interest rates are putting data center business models at risk.
- Chinese NAND rivals are closing in on the memory supplier.
