Business
Kioxia Holdings traces its technological origins to the invention of the world's first NAND-type flash memory in 1987, and is now a flash memory pure-play group comprising 22 consolidated subsidiaries. The company manufactures flash memory chips at two sites—the Yokkaichi Plant (Mie Prefecture) and the Kitakami Plant (Iwate Prefecture)—and sells SSDs, Embedded Memory, and retail products worldwide. Its major customers include global smartphone makers led by the Apple group (20.4% of revenue), data center operators, and enterprise customers, and through a manufacturing joint venture with the Sandisk group (sharing approximately 80% of production capacity), the company holds a global share of approximately 29% on a bit production basis.
Business Model
Built around its proprietary BiCS FLASH™ technology, the company manufactures flash memory at its large-scale Yokkaichi and Kitakami plants and sells it worldwide as SSDs, embedded memory, and retail products. The manufacturing joint venture with the Sandisk group has been converted into a contract under which the company will receive a total of US$1,165 million in manufacturing service consideration from 2026 through 2029. While also utilizing government subsidies (¥56,396 million in FY2026 (ending March 2026)), the company disciplined capital investment, aiming to maximize profitability by reducing cost per gigabyte and expanding shipment volume.
Company Strengths
Including the joint venture with the SanDisk group, the company holds a global share of approximately 29% on a bit production basis, and has established an integrated production system at the Yokkaichi Plant, connecting six fabrication buildings via inter-building transport. The second fabrication building (K2) at the Kitakami Plant began operations in September 2025. The company has achieved high production efficiency through smart factory initiatives leveraging AI and big data.
The company is in mass production of 8th-generation BiCS FLASH™, which employs CBA (CMOS directly Bonded to Array) and OPS (On Pitch SGD) technologies. It has launched the "CM9 series" enterprise SSD, which achieves approximately 65% improvement in random write performance and approximately 95% improvement in sequential write performance compared to the previous generation, achieving both cost competitiveness and product competitiveness underpinned by technological capability.
Sales to the Apple group accounted for 20.4% of revenue in FY2026 (ending March 2026), up from 17.6% in the previous fiscal year, deepening the relationship with its largest customer. In the smartphone segment, the company has built strong relationships with major global companies over many years, with a track record of providing high-quality products and support that meet cutting-edge technology needs.
ENVALITH's Perspective
Performance Trend
For FY2026 (ending March 2026), revenue reached ¥2,337,628 million (up 37.0% year on year), operating profit reached ¥870,369 million (up 92.7% year on year), and profit attributable to owners of parent reached ¥554,490 million (up 103.6% year on year), setting record highs across all metrics. The primary external factor was a sharp rise in average selling prices and an increase in shipment volumes driven by expanding demand for data centers, particularly for generative AI applications. The revenue-to-operating-profit margin improved substantially to 37.2% (from 26.5% in the prior period). By application, SSD & Storage generated ¥1,362,638 million (up 37.5% year on year) and Smart Devices generated ¥759,978 million (up 51.7% year on year), with both segments driving growth. For Q1 FY2027 (ending March 2027), revenue is forecast at ¥1,750,000 million (up 74.5% quarter on quarter) and operating profit at ¥1,298,000 million (up 117.5% quarter on quarter), indicating continued acceleration.
Growth Strategy
Continuing to capture AI demand through mass production of 8th-generation BiCS FLASH™ and expansion of data center SSD market share
Advancing mass production of 8th-generation BiCS FLASH™ employing CBA (CMOS Bonded Array) and OPS technology, achieving reductions in cost per bit and higher density. This will strengthen competitiveness of high-value-added SSD products for data centers and enterprise applications.
Against a backdrop of increased server demand driven by generative AI applications, revenue in the SSD & Storage segment reached ¥1,362,638 million in FY2026 (ending March 2026), up 37.5% year-on-year. Strong demand for data center applications is expected to continue in Q1 FY2027 (ending March 2027), with revenue and profit both projected to increase.
In July 2025, ¥322,996 million of non-convertible preferred shares were redeemed, streamlining the capital structure. Newly issued US dollar-denominated unsecured ordinary bonds of ¥326,656 million to diversify funding sources. Early repayment of borrowings and termination of related agreements are scheduled for April and May 2026, promoting reductions in financing costs and improved financial flexibility.
Kioxia Corporation completed the acquisition of shares in Nanya Technology Corporation on April 8, 2026 (acquisition consideration of ¥78,208 million). This aims to strengthen the strategic partnership and expand the business foundation in the memory business.
