Kioxia H1 FY3/2027 earnings summary

AI datacenter demand lifts every application

Kioxia Holdings Corporation (TSE: 285A) reported consolidated IFRS results for the first half of FY3/2027, April 1 to September 30, 2026, on October 30, 2026. Revenue rose 436.8% to ¥4,247.2 billion from ¥791.1 billion, which the company attributed to strong demand from datacenter customers centred on generative-AI applications, a sharp rise in average selling prices, higher bit shipments and a weaker yen: the average dollar rate was ¥160 against ¥146 a year earlier. By application, SSD & Storage revenue reached ¥2,790.7 billion against ¥462.0 billion, Smart Devices ¥1,314.5 billion against ¥236.3 billion and Other ¥141.9 billion against ¥92.8 billion. Kioxia said smartphone and PC demand was slowing while demand for AI servers kept the market expanding. Gross profit rose to ¥3,433.2 billion, for a gross margin of 80.8% against 24.4%, and the operating margin reached 76.9% against 16.5%. Operating profit absorbed a ¥36.6 billion litigation provision, a special profit-sharing payment to employees and ¥13.0 billion of share-based compensation; excluding such items, Non-GAAP operating profit was ¥3,314.5 billion. Profit before tax was ¥3,203.4 billion and basic earnings per share ¥1,349.33 against ¥36.42, both restated for the three-for-one stock split that took effect on October 1, 2026.

Second quarter beats the company's own guidance

In the second quarter alone, July to September, revenue rose ¥712.9 billion from the first quarter to ¥2,480.0 billion, ahead of the ¥2,390.0 billion Kioxia had guided in July; SSD & Storage contributed ¥1,616.0 billion and Smart Devices ¥788.9 billion. Operating profit was ¥1,994.7 billion against ¥1,270.0 billion in the first quarter and guidance of ¥1,890.0 billion, helped by the absence of a litigation charge and a ¥6.4 billion reversal of share-based compensation. Profit attributable to owners of the parent was ¥1,355.7 billion against guidance of ¥1,270.0 billion.

Flat third quarter, first dividend and ¥800 billion buyback

Kioxia does not publish a full-year plan and guides one quarter at a time. For October to December it expects revenue of ¥2,500.0 billion, up 0.8% on the second quarter, operating profit of ¥1,995.0 billion, Non-GAAP operating profit of ¥2,000.0 billion and profit attributable to owners of ¥1,360.0 billion, for basic earnings per share of ¥851.11: datacenter demand is expected to stay strong, but the company assumes a less favourable dollar rate of ¥157 against ¥161. Cumulative nine-month revenue would be ¥6,747.2 billion, up 405.5%. Having paid no dividend for FY3/2026, Kioxia revised its dividend forecast and declared an interim dividend of ¥90 per share, stated before the stock split, payable from December 8; it gave no year-end forecast. It bought back ¥800.0 billion of its own shares and repaid ¥523.1 billion of long-term borrowings, partly ahead of schedule. Operating cash flow reached ¥2,379.6 billion against ¥175.2 billion and cash rose ¥926.6 billion to ¥1,397.3 billion. Total assets grew to ¥5,883.9 billion from ¥3,690.1 billion and the owners' equity ratio improved to 49.8% from 37.9%.
