Kioxia Holdings Corporation (ISIN JP3236330001) was upgraded to BBB from BBB- with a positive outlook on October 13, 2026, while its euro quotation stood at EUR 73.32 at Lang & Schwarz on October 15, 2026 at 11:00 a.m. CEST. The rating action gives investors a fresh measure of how the artificial intelligence memory cycle is changing the company profile.

Credit quality rises with earnings

S&P Global Ratings said on October 13, 2026 that Kioxia's earnings over the next two years could exceed its previous assumptions. The agency projects adjusted EBITDA of JPY 7 trillion to JPY 8 trillion for fiscal 2026 ending March 31, 2027, followed by about JPY 9 trillion for fiscal 2027.

The forecast compares with adjusted EBITDA of JPY 1.185 trillion in fiscal 2025 in the same S&P assessment. That implies a sharp change in scale, although memory pricing, competition and data-center investment remain material variables for the forecast.

Cooling targets AI servers

Kioxia announced direct liquid cooling models for its CM9 enterprise SSD series on October 13, 2026. The E3.S products support capacities up to 30.72 terabytes for read-intensive use and 25.6 terabytes for mixed-use endurance, with sampling under way for selected customers, according to Business Wire. The products are designed for high-performance environments where server power density is increasing.

Kioxia's investor-relations page identifies the shares as TSE Prime ticker 285A and lists the second-quarter fiscal 2026 results for October 30, 2026 at 6:45 p.m. Japan time. The same page records the October 13 credit-rating release, linking the rating event with the company's upcoming reporting date.

Tokyo valuation reflects the risk

The primary-market quotation was last at JPY 12,880 on the Tokyo Stock Exchange on October 15, 2026 at 3:30 p.m. JST, according to the finance snapshot. Its market capitalization was JPY 21.1 trillion at that time, while the reported 52-week range was JPY 1,950 to JPY 37,566.67. The large spread shows why the stronger earnings outlook does not remove the memory cycle risk.
