Thanks to a shortage of memory, Kioxia entered the top 10 most expensive Japanese companies

Kioxia enters the top ten largest Japanese companies by market capitalization

As a result of the global memory chip shortage and rising prices, Kioxia has entered the list of the ten largest Japanese firms by share market value for the first time. At the close of trading its capitalization reached 19.3 trillion yen (≈ $121 billion), moving it up to tenth place – the previous ranking was 43rd.

- Money in shares: within one day, the price rose by 1.7%, helped by a general increase in prices for AI‑related companies.

- Record high: as of now, Kioxia’s market assets have reached an all‑time high since its IPO in December 2024.

Why are memory prices rising?

Global demand for NAND memory used in AI servers has surged sharply. American technology giants are boosting investments in this segment, driving up the stocks of manufacturers such as SanDisk and Samsung. Since the beginning of the year, Kioxia’s share price has more than tripled, surpassing market figures for Mitsubishi Corp., Mizuho Financial Group, and Mitsubishi Heavy Industries.

Financial expectations

Analysts forecast that the company’s net profit for the current fiscal year (ending in March) will rise to 2.5 trillion yen ($15.66 billion), making it Japan’s second‑most profitable company after Toyota.

- The current P/E ratio is below 8, indicating an upward trend.

- Shares are sought after by retail traders and hedge funds due to high volatility.

Thus, Kioxia has not only entered the top ten largest Japanese companies by market capitalization but also demonstrates significant growth in both share price and expected earnings.
