Why did Kioxia clear a trillion yen with profit up 28-fold and still miss the market?
Kioxia's April to June operating profit came to 1.27 trillion yen, 28 times the 44.9 billion yen it earned a year earlier. The number the market was waiting for was 1.3701 trillion yen, and the company's own guidance of 1.3 trillion yen was not met either.
Kioxia quarterly operating profit tops 1 trillion yen, misses estimates (Seoul Economic Daily English, 2026-07-31)Both revenue and profit came in under consensus, and profit missed by more. Revenue cleared the company's own 1.75 trillion yen guidance while operating profit fell short of the 1.3 trillion guidance. The shortfall is not in how much was sold but somewhere between the sale and the profit line.

Why this company reads differently
Samsung and SK hynix make both DRAM and NAND. When one price falls the other holds them up, which makes it hard to read the NAND market off their results. Kioxia makes NAND and nothing else. So its quarterly numbers show where NAND pricing sits in the least blended form available.
What made that fourfold revenue
The slide deck carries the two numbers that split the revenue line. Bit shipments grew by a low single-digit percentage, and the average selling price rose about 70%. Bit shipments are the total storage capacity sold. So the company sold roughly the same amount as the prior quarter, and revenue quadrupling came almost entirely from price. Selling the same volume at a higher price sends margin up sharply. Non-GAAP operating margin came in at 75%. That it still missed consensus means the market had already booked a bigger price increase than the one that arrived.
What the company sees next quarter
July to September guidance is revenue of 2.39 trillion yen, up 35.2% sequentially, and operating profit of 1.89 trillion yen, up 48.8%. Management expects demand to exceed supply in 2027 as well. Over the same period it repaid 407.5 billion yen of senior loans in full and swung to a net cash position of 186.7 billion yen. Gross capital spending was 52.4 billion yen, with a separate 78.2 billion yen placed into Nanya Technology for next-generation stacked NAND capacity.
So what settles it
The question comes down to one thing. Whether this miss is the first sign of prices turning, or expectations having run ahead of them. Next quarter's average selling price settles it. If price keeps rising through the September quarter and operating profit reaches the 1.89 trillion the company guided, what ran ahead was expectation, and if the price increase flattens, this miss was the first signal. Price rallies in NAND have always ended when volume followed. This time volume has barely moved. While bit shipments sit in the low single digits, price is moving alone.
- Kioxia's April to June operating profit reached 1.27 trillion yen, 28 times what it earned a year earlier.
- On the surface it is an overwhelming quarter for a NAND maker riding AI demand.
- But revenue missed consensus by 3.7% and operating profit by 7.3%, and that fourfold revenue came almost entirely from a roughly 70% rise in price rather than volume.
What happened next
Awaiting gradingScore on Kioxia's fiscal Q2 2026 results for July to September. If operating profit reaches the 1.89 trillion yen the company guided, this miss was expectations running ahead, and if the average selling price increase flattens and profit falls well short, it was the first sign of prices turning.
