MINEBEA MITSUMI Inc.

Business Details

Core products include Ball Bearings (holding a globally high share in miniature small-diameter bearings with outer diameters of 22mm or less), Rod End Bearings, mechanical parts such as HDD Pivot Assemblies, and Aircraft Screws. With server demand for data centers, aircraft-related demand, and HDD-related demand as its main customer base, the segment achieves high profitability through a globally vertically integrated production system spanning Japan, Thailand, Singapore, China, Cambodia, the United States, and Europe.

Recent Overview

Achieved higher revenue and profit on solid data center and aircraft demand, maintaining an operating margin above 22%

In FY2026 (ending March 2026), revenue reached ¥281,151 million (up ¥25,449 million, or 10.0%, year on year) and operating profit reached ¥62,245 million (up ¥6,549 million, or 11.8%, year on year), achieving higher revenue and profit. The main driver was solid performance in both server demand for data centers and aircraft demand for the core Ball Bearings product. The operating profit margin improved to 22.1% from 21.8% in the prior period, maintaining the highest profitability level within the group. Impairment losses were zero (compared to ¥621 million in the prior period).

Key Products

Growth Drivers

• Continued increase in demand for Ball Bearings used in servers and Fan Motors amid expanding data center investment
• Increased sales of Rod End Bearings and Aircraft Screws driven by the recovery and expansion of aircraft-related demand
• Steady trend in demand for HDD Pivot Assemblies
• High price competitiveness and cost reduction through ultra-precision machining technology and a vertically integrated production system
• Risk diversification and supply stability through a global multi-site production system (Thailand, Singapore, China, Cambodia, the U.S., and Europe)

Risks

• Risk of demand fluctuation due to uncertainty in the global economic outlook against the backdrop of reciprocal tariff increases by the United States
• Risk of a sharp decline in Ball Bearings demand due to fluctuations in the data center investment cycle
• Risk of structural decline in Pivot Assembly demand due to the long-term shrinking trend in the HDD market
• Geopolitical and natural disaster risks associated with concentration of production sites in Thailand, China, and other parts of Asia
• Foreign exchange risk (major production sites are overseas, and the majority of sales are to overseas customers)
