Business Details
Manufactures and sells transistors, diodes, SiC/Si Power Devices, Light Emitting Diodes (LED), and Semiconductor Lasers. Primary customers are in the automotive market (SiC Power Devices for xEV), industrial equipment market, and computer & storage market. Due to slowing growth in the BEV market, a large-scale impairment was recorded primarily on SiC fixed assets, but sales are on a recovery trend, up 9.7% year on year. This is a strategically core segment accounting for the majority of the group's overall capital expenditure, and structural reforms are underway.
Recent Overview
Recorded a large-scale impairment of ¥191,648 million on SiC fixed assets, while sales recovered, up 9.7% year on year
In FY2026 (ending March 2026), it became clear that the medium-term growth rate of the BEV market would fall below previous forecasts, leading to an impairment loss of ¥191,648 million (a significant increase from ¥17,605 million in the prior period) recorded primarily on fixed assets in the SiC business. As a result, segment assets decreased significantly from ¥377,428 million to ¥225,178 million. On the other hand, sales recovered to ¥205,263 million (up 9.7% year on year), and the segment loss improved to ¥22,704 million (versus a loss of ¥45,899 million in the prior period). The change in depreciation method from the declining-balance method to the straight-line method had the effect of reducing the segment loss by ¥7,833 million. Capital expenditure was also significantly reduced to ¥69,099 million (from ¥111,255 million in the prior period), reflecting a shift toward restraining increases in fixed costs.
Key Products

Business Details
The Modules segment consists of two businesses: Print Heads and Optical Modules. Print Heads are used mainly in office equipment and payment terminals, while automotive LED modules are the main product in Optical Modules. Even as the overall group posted a net loss for two consecutive periods, this segment maintained profitability, with segment profit of ¥3,522 million in FY2026 (ending March 2026). Although its sales scale is small at approximately 6.6% of the group's overall total, it has a notable presence in terms of earnings stability.
Recent Overview
Sales down 3.0% year on year, but profit up 30.9% year on year on improved margin
In the Modules segment for FY2026 (ending March 2026), sales decreased to ¥31,589 million (down 3.0% year on year) due to the impact of lower sales of automotive LED modules. On the other hand, in addition to increased sales of Print Heads for office equipment, the change in depreciation method from the declining-balance method to the straight-line method (increasing segment profit by ¥290 million) contributed to a significant increase in segment profit, which rose to ¥3,522 million (up 30.9% year on year). The profit margin improved from 8.3% to 11.2%.
