Business Details

Comprised of Torex Semiconductor Ltd. and Phenitec Semiconductor Corporation. The former develops and sells Analog Power ICs (DC/DC Converter, Regulator, Detector, etc.), while the latter is responsible for front-end wafer manufacturing and sales of Discrete products (transistors, diodes, IGBTs, etc.). The Japan segment also manages outsourced manufacturing partners, building a structure that leverages the advantages of both the fabless model and in-house manufacturing. In FY2026 (ending March 2026), increased sales for industrial equipment applications drove a turnaround to profitability from a substantial loss in the prior period.

Recent Overview

Increased sales for industrial equipment applications drove a turnaround to profitability from a substantial loss in the prior period.

In FY2026 (ending March 2026), Japan segment sales were ¥17,373 million (up 4.8% year on year), and segment profit was ¥837 million (versus a segment loss of ¥863 million in the prior period), a substantial improvement. The main driver was increased sales for industrial equipment applications. The impairment loss of ¥1,116 million recorded in the prior period was zero in the current period, normalizing the earnings structure. In addition, the company has entered into an agreement to transfer a 95% equity stake in TOREX VIETNAM SEMICONDUCTOR CO., LTD. for the purpose of a business alliance with PANJIT INTERNATIONAL INC., and procedures are underway. At Phenitec Semiconductor, an update to core systems is being advanced (software in progress increased by ¥657 million).

Key Products

product
DC/DC Converter (DCDC)

Available in a wide variety of types, including step-down, step-up, and step-up/step-down, efficiently converting voltage to a desired value. Consolidated sales for FY2026 (ending March 2026) were ¥3,466 million (down 8.1% year on year), the only product category to see a decline in sales.

product
Voltage Regulator (VR)

Consolidated sales for FY2026 (ending March 2026) grew steadily to ¥4,714 million (up 8.5% year on year). Demand recovered mainly for industrial equipment and automotive equipment applications.

product
Voltage Detector (VD)

Consolidated sales for FY2026 (ending March 2026) recorded the highest growth rate at ¥1,811 million (up 14.7% year on year). Demand is expanding on the back of needs for miniaturization and power savings.

product
Discrete (Phenitec Semiconductor)

Phenitec Semiconductor Corporation handles front-end wafer manufacturing and sales at domestic plants. Consolidated sales for FY2026 (ending March 2026) were ¥14,315 million (up 6.5% year on year), the group's largest product category. Efforts toward the power semiconductor business are being advanced through a joint project with Torex.

product
Others (Sensors, Multi-Chip Modules, etc.)

Consolidated sales for FY2026 (ending March 2026) were ¥764 million (down 6.2% year on year). This includes module products equipped with multiple ICs and various sensors.

Growth Drivers

  • Expansion of sales of high-value-added products for the three priority fields of industrial equipment, automotive equipment, and medical equipment (tailwinds from IoT, automation, and EV trends)
  • Synergy effects with Phenitec Semiconductor (joint efforts in the power semiconductor business, cost reduction, and quality improvement collaboration)
  • Increase in foundry outsourcing orders from Asian companies due to the China-plus-one strategy
  • Gradual recovery of the semiconductor market as inventory adjustments are largely resolved (boosting demand for industrial and medical equipment)
  • Improvement of earnings structure and operating margin through continued cost control (reduction of SG&A expenses)

Risks

  • Continued risk of procurement constraints for PC, smartphone, and consumer equipment components due to memory supply-demand tightness amid growing AI-related demand
  • Risk of rising manufacturing costs due to soaring material costs, including gold (a challenge across the semiconductor manufacturing sector)
  • Risk of additional impairment losses on fixed assets such as Phenitec Semiconductor plants (concern about recurrence of the ¥1,116 million recorded in the prior fiscal year)
  • Risk of delayed recovery in demand for Asia due to continued weakness in the Chinese market
  • Risk of adverse effects on the real economy and downside risk to semiconductor demand due to geopolitical risks (Middle East situation, changes in trade policy)
  • Risk of increased investment burden and operational transition risk associated with the core system update (Phenitec Semiconductor)
