Business Details

The company operates the manufacture and sale of Stationary Gas Detection & Alarm Equipment, Portable Gas Detection & Alarm Equipment, and Other Measuring Equipment, along with After-sales Maintenance Service, as a single segment. Major customers include domestic and overseas industries such as semiconductors, petrochemicals, shipbuilding, and gas. In FY2026 (ending March 2026), the domestic sales ratio was 52.7% and overseas 47.3% (Asia 24.3%, North America 18.3%, Europe 3.9%). The company operates globally through 8 consolidated subsidiaries (Taiwan, China, the U.S., Singapore, Germany, etc.). Against a backdrop of expanding semiconductor demand for generative AI and data centers and strong performance of portable equipment in North America, the company achieved increased revenue and profit.

Recent Overview

Driven by semiconductor and North American demand, the company achieved substantial growth with revenue up 12.6% and operating profit up 16.8%

In FY2026 (ending March 2026), against a backdrop of expanding semiconductor investment for generative AI and data centers, both categories saw increased sales, with Stationary equipment reaching ¥33,616 million (up 7.8% year on year) and Portable equipment reaching ¥20,238 million (up 22.6% year on year). North American sales expanded to ¥9,634 million (from ¥8,184 million in the prior period), and the overseas sales ratio rose to 47.3% (from 44.0% in the prior period). The recording of a foreign exchange gain of ¥512 million (versus a loss of ¥249 million in the prior period) also boosted ordinary profit, which increased 24.1% to ¥13,443 million. Order backlog increased by ¥5,250 million from the end of the previous fiscal year to ¥18,426 million, providing a favorable carryover into the next fiscal year. The year-end dividend was increased from ¥25 to ¥30, bringing the annual dividend to ¥55 (up from ¥45 in the prior period). For FY2027 (ending March 2027), the company forecasts revenue of ¥60,000 million (up 8.7% year on year) and operating profit of ¥12,700 million (up 2.2% year on year).

Key Products

product
Stationary Gas Detection & Alarm Equipment

Sales to the semiconductor industry were strong, driven by increased demand for generative AI and data centers. Sales to the gas industry and shipbuilding industry, as well as domestic replacement demand, were also solid. Including After-sales Maintenance Service, sales in FY2026 (ending March 2026) were ¥33,616 million (up 7.8% year on year). Order backlog stood at ¥8,319 million.

product
Portable Gas Detection & Alarm Equipment

Sales expanded domestically mainly to the petrochemical and shipbuilding industries, and overseas to a broad range of industries in North America. After-sales Maintenance Service also performed steadily. Sales in FY2026 (ending March 2026) grew strongly to ¥20,238 million (up 22.6% year on year). Order backlog increased by ¥4,718 million from the end of the previous fiscal year to ¥9,328 million, becoming the largest category, accounting for 50.6% of the total order backlog.

product
Other Measuring Equipment

The product has a track record of use across a wide range of industries and academic fields. Sales in FY2026 (ending March 2026) were nearly flat at ¥1,356 million (up 0.6% year on year). The company continues to develop the market by expanding into providing solutions for realizing a decarbonized society and preventing global warming.

service
After-sales Maintenance Service

Performance remained steady for both Stationary and Portable Gas Detection & Alarm Equipment. It forms a value-provision system integrated with product sales, meeting customers' quality and delivery requirements. It serves as a stock-type revenue source that contributes to earnings stability.

Growth Drivers

  • Continued robust demand for Stationary Gas Detection & Alarm Equipment for the semiconductor industry, driven by expanding semiconductor investment for generative AI and data centers
  • Expanded sales of the Portable Gas Detection & Alarm Equipment 'GX-3R Series' to a broad range of industries, mainly in North America (up 22.6% year on year in FY2026, ending March 2026)
  • Expanded market share through strengthened development and sales of multi-point tape-type gas detection and alarm equipment for the overseas semiconductor market
  • Continued expansion of the overseas sales ratio (from 44.0% to 47.3%) and strengthened sales structure in the North American and Asian markets
  • Cumulative effect on next-period performance from an order backlog of ¥18,426 million (up ¥5,250 million from the end of the previous fiscal year)
  • Steady accumulation of stock-type revenue driven by solid performance of After-sales Maintenance Service
  • Maintaining and enhancing competitiveness through continued development of advanced detection technologies, including gas visualization

Risks

  • Risk of sudden changes in demand from major customers due to fluctuations in the semiconductor industry's capital investment cycle
  • Risk of intensifying trade friction due to U.S. trade and tariff policy, leading to deterioration of the business environment in the North American and Asian markets
  • Foreign exchange risk (a foreign exchange gain of ¥512 million was recorded in FY2026, ending March 2026, but a reversal could pressure ordinary profit)
  • Risk of rising costs due to increases in labor costs (salaries and allowances of ¥4,051 million, up ¥223 million year on year) and raw material prices
  • Impact on the supply chain and demand from geopolitical risks such as the situations in the Middle East and Ukraine
  • Risk of impact on sales to East Asia (China sales of ¥6,759 million) due to uncertainty in the Chinese economy
  • For FY2027 (ending March 2027), the company forecasts declines in ordinary profit (down 3.3% year on year) and net profit (down 3.6% year on year), making the maintenance of profitability a challenge
