AOI ELECTRONICS CO.,LTD.

Business Details

The AOI Electronics Group's core business is the manufacture and sale of Integrated Circuits (ICs, optical sensors, wafer-level packages, LEDs, etc.) and Functional Components (thermal print heads, various sensors, etc.). Its major customers are Nichia Corporation, MITSUMI ELECTRIC CO., LTD., and Nisshinbo Micro Devices Inc., resulting in high customer concentration. The group comprises three consolidated subsidiaries (High Components Aomori, Ome Electronics, and Hayama Kogyo) and one equity-method affiliate (Vinex). The company is actively pursuing capital investment for advanced fields at its Taki Plant in Mie Prefecture.

Recent Overview

Net sales rose 9.6%, but operating profit fell 30.2% due to soaring raw material costs and expanded upfront investment

In FY2026 (ending March 2026), the company achieved higher sales of ¥38,323 million (up 9.6% year on year), but operating profit fell to ¥306 million (down 30.2% year on year) due to soaring prices of raw materials, including precious metals, and increased R&D expenses for advanced fields. Ordinary profit rose substantially to ¥728 million (up 73.8% year on year), supported by non-operating income including technical royalty income of ¥238 million and foreign exchange gains of ¥102 million. On the other hand, profit for the period was limited to ¥70 million (down 60.6% year on year) due to the recognition of an impairment loss of ¥252 million. Long-term borrowings increased sharply due to capital investment at the Taki Plant in Mie Prefecture (acquisition of property, plant and equipment of ¥11,359 million), and the equity ratio declined from 83.2% to 69.0%. For FY2027 (ending March 2027), the company plans to change its depreciation method from the declining-balance method to the straight-line method (with an effect of reducing depreciation expense by ¥1,430 million), and forecasts net sales of ¥44,000 million and net profit of ¥230 million.

Key Products

Growth Drivers

• Increased orders for Integrated Circuits used in mobile information devices and consumer equipment (Integrated Circuits sales of ¥33,874 million, up 10.4% year on year)
• Recovery in orders for Functional Components driven by progress in inventory adjustment for thermal print heads (Functional Components sales of ¥4,445 million, up 4.2% year on year)
• Solid demand in data center and advanced semiconductor-related fields, supported by the spread of generative AI and advances in AI technology
• Active promotion of capital investment and R&D investment in new business fields such as advanced packaging at the Taki Plant in Mie Prefecture
• Reduction effect of ¥1,430 million in depreciation expense from the change in depreciation method (declining-balance to straight-line) starting FY2027 (ending March 2027)
• Contribution to ordinary profit from a significant increase in technical royalty income received (from ¥22 million to ¥238 million)

Risks

• Upward pressure on cost of sales ratio due to soaring prices of raw materials, including precious metals (cost of sales ratio of 84.1%)
• Risk of sales fluctuation due to customer concentration in Nichia Corporation, MITSUMI ELECTRIC CO., LTD., and Nisshinbo Micro Devices Inc.
• Continued weakness in automotive components due to slowing demand growth in the electric vehicle (EV) market
• Uncertainty in the business environment due to heightened geopolitical risk and supply chain restructuring
• Increased financial leverage and decline in equity ratio (from 83.2% to 69.0%) due to a sharp rise in long-term borrowings (from ¥474 million to ¥9,471 million) associated with expanded upfront investment
• Risk of profit pressure from increased depreciation and R&D expenses associated with large-scale upfront investment at the Taki Plant in Mie Prefecture (construction in progress of ¥8,978 million)
• Risk of recognizing impairment losses (¥252 million recognized in the current period)
