Kioxia (ISIN JP3236330001) traded at EUR 83.17 at Lang & Schwarz at 12:48 p.m. CEST on October 14, 2026. On October 13, 2026, S&P Global Ratings raised Kioxia Holdings from BBB- to BBB and assigned a positive outlook.

Why the upgrade matters

The rating action links Kioxia's stronger credit profile to NAND flash memory and solid-state drive demand from AI data centers. S&P projects adjusted EBITDA of JPY 7 trillion to JPY 8 trillion in fiscal 2026, rising to JPY 9 trillion in fiscal 2027, while identifying Chinese competition and potential data-center spending cuts as risks.

The agency also said Kioxia reached a net cash position as of June 30, 2026. Its scenario assumes that long-term agreements will cover 50 percent of shipment volumes by 2028, a structure intended to reduce the earnings volatility typical of memory markets.

Quarterly numbers show the leverage

Moat Explorer reported that Kioxia's first-quarter fiscal 2026 revenue reached JPY 1,767.1 billion for the three months ended June 30, 2026, up 415.5 percent from the prior-year quarter. The same period carried a non-GAAP operating margin of 75 percent, showing how sharply pricing conditions affected profitability.

Three dated company signals

Kioxia scheduled its second-quarter fiscal 2026 results for October 30, 2026, after announcing an investment plan with Sandisk on August 27, 2026 and publishing its media-report notice on September 15, 2026. The October 13, 2026 rating upgrade is the latest of these dated signals.

What does the upgrade mean?

The financial picture is improving, but the outlook remains tied to memory pricing and AI infrastructure demand. Kioxia's Tokyo listing is 285A, and its market capitalization was JPY 24.1 trillion on October 14, 2026, while the 52-week range was JPY 1,950.00 to JPY 37,566.67.
