[Summary]
Kioxia Holdings (285A) is attracting a lot of attention in the market due to demand for AI data centers, improving NAND flash memory market conditions, inclusion in the Nikkei Stock Average, and announcement of preparations for listing American Depositary Shares (ADS).
In the fiscal year ending March 2026, sales revenue was 2,337.6 billion yen, operating profit was 870.4 billion yen, and profit attributable to owners of the parent company was 554.5 billion yen. The forecast for the first quarter of the fiscal year ending March 2027 is also at a high level, but the rate of change in the report is a "comparison with the previous quarter," so caution should be taken when expressing a simple year-on-year change.
The focus in the second half of 2026 will be the continuation of AI storage demand, the sustainability of NAND market conditions, competitors' stance on increasing production, common stock dividend policy, and the progress of ADS listing preparations.
First, the conclusion
When looking at Kioxia, it is important not to simply view it as an "AI-related stock."
More precisely,
“NAND market stocks benefiting from AI storage demand”
need to be viewed as such.
Currently, demand for data centers and enterprises, including those for AI applications, is pushing up performance. On the other hand, prices of NAND flash memory fluctuate significantly due to supply increases and inventory adjustments. Therefore, the second half of 2026 is likely to be a period where "growth expectations" and "silicon cycle caution" are likely to be factored in at the same time.
Three factors that supported the rapid rise
Demand and performance recovery for AI data centers
In the financial results for the fiscal year ending March 2026 announced on May 15, 2026, sales revenue was 2,337.6 billion yen, operating profit was 870.4 billion yen, and profit attributable to the parent company was 554.5 billion yen.
The company explains that in the flash memory market, in addition to a recovery in demand for smartphones and PCs, demand for servers in data centers and enterprises for AI applications is increasing.
The forecast for the first quarter of the fiscal year ending March 2027 is as follows.
| Item | 1Q forecast for the fiscal year ending March 2027 | Change rate |
|---|---|---|
| Revenue | 1.75 trillion yen | +74.5% |
| Non-GAAP operating income | 1.3 trillion yen | +117.0% |
| Operating income | 1,298 billion yen | +117.5% |
| Non-GAAP quarterly profit attributable to parent company | 870 billion yen | +112.2% |
| Quarterly profit attributable to parent company | 869 billion yen | +113.1% |
This rate of increase/decrease is compared to the previous quarter in the short report. It is true that this is a strong forecast, but if you read it only in terms of a multiple of the previous year's figure, you may be misreading the comparison.
Changes in supply and demand due to Nikkei average adoption
KIOXIA was included in the Nikkei Stock Average from the start of trading on April 1, 2026.
Adopting an index tends to generate rebalancing demand for funds that track the Nikkei 225 average. Although this could be a factor in supply and demand, it cannot be concluded that it will permanently support stock prices. Actual stock prices fluctuate depending on business performance, index supply and demand, overall market risk tolerance, and expectations for the semiconductor sector.
Announcement of ADS listing preparations
On May 15, 2026, the company announced that it is preparing to list American Depositary Shares (ADS) of its common stock on the US stock exchange.
The company says it aims to expand its investor base and improve corporate value. However, this is subject to approval from the relevant authorities, and the expected timing, market, and method have not yet been determined. Since it is clearly stated that there is a possibility that the stock may not be listed depending on the results of the review, it should be treated as "material that requires progress confirmation" rather than a confirmed event.
Valuation level of market capitalization of 24 trillion yen
Simply multiplying the closing price of 44,450 yen on May 15, 2026 by the number of outstanding shares of 546,086,290 shares at the end of the fiscal year ending March 2026, the market capitalization is approximately 24.3 trillion yen.
This is a very large scale even in the Japanese stock market, and in order for stock prices to rise further, it will not only be thematic, but also the sustainability of profit levels, cash generation, return policy to common stock, and the appropriateness of valuations from the perspective of global investors.
For stocks that have experienced a sharp rise, favorable factors may already have been factored into the stock price to a considerable extent. Even if financial results are strong, stock prices can fall if they fall short of expectations.
Focus on shareholder returns
KIOXIA's common stock dividend was 0 yen per year for both the fiscal year ending March 2025 and the fiscal year ending March 2026.
The forecast for the fiscal year ending March 2027 is that the dividend at the end of the second quarter will be 0 yen, and the year-end dividend and annual dividend are undetermined. The company says it will promptly disclose the dividend forecast once it has decided on it.
Therefore, it cannot be said that "the start of dividends has been decided" at this point. Investors should check the next financial results,
- Common stock dividend policy
- Presence or absence of stock buybacks
- Balance with capital investment
- Trends in interest-bearing debt and cash balance
- Is the return level sustainable even when market conditions deteriorate?
is shown.
Silicon cycle to be wary of
Increase in supply due to increased production by competitors
Prices of NAND flash memory tend to rise when demand is strong, but it also tends to be oversupplied when competitors resume investment or increase production.
The investment stance of Samsung, SK hynix, Micron, Western Digital, YMTC, etc. will affect Kioxia's profit margin. If competitors rush to increase NAND production, downward pressure on prices could increase from the second half of 2026 to 2027.
Performance peak out warning
Stock markets try to factor in not only current business performance but also changes over the next six months to a year.
Precisely because the forecasts for the first quarter of the fiscal year ending March 2026 and the fiscal year ending March 2027 are strong, the market is asking whether this profit margin will be sustainable. Even after good financial results are achieved, if growth in NAND prices and shipments slows, profit-taking and valuation adjustments may occur.
Indicators to watch in the second half of 2026
Stock prices are not the only indicators you want to check.
| Indicators to look at | Meanings to check |
|---|---|
| NAND spot price | Direction of unit sales price |
| eSSD demand | Sustainability of demand for AI data centers |
| Competitive CAPEX | Oversupply Risk |
| Number of outstanding shares and market capitalization | Weight of valuation |
| Operating CF | Turning profits into cash |
| Dividend policy | Evaluation materials for medium- to long-term investors |
| Preparation for ADS listing | Progress in expanding investor base |
Summary
In the second half of 2026, Kioxia's tailwind from demand for AI data centers will collide head-on with the risk of a reversal in NAND market conditions.
The adoption of the Nikkei Stock Average and preparations for ADS listing are important factors in terms of supply and demand and the investor base, but they are not guarantees that stock prices will move in one direction. Considering the current size of the market capitalization, sustainability of profit margins, cash generation, and return policy to common stock will be more important than themes.
When making investment decisions, it is important to check not only the strength of financial results, but also the NAND price, competitive investments, dividend policy, and the progress of ADS listing preparations.
