Business Details

Provides an integrated offering of construction materials such as Post-installed Anchors, drills, and fasteners, spanning planning and development through manufacturing, sales, and installation tools. Also handles seismic reinforcement projects, various maintenance and repair projects, construction management for solar-related projects, and the manufacture and sale of Electro-hydraulic Tools (rebar cutters, benders, etc.). In FY2026 (ending March 2026), the company made Kofu Seibyo Co., Ltd. and KOHBYO (THAILAND) Co., Ltd. subsidiaries, strengthening its micro components manufacturing capabilities. This core segment accounts for approximately 79% of group sales, with the construction, civil engineering, and infrastructure markets as its primary customers.

Recent Overview

Net sales down 1.6% year on year, but profit up 11.0% owing to a profitability focus; Kofu Seibyo made a subsidiary

In the Fastening Business for FY2026 (ending March 2026), sales of Post-installed Anchors were slightly below the prior year, and completed construction revenue also fell below the prior year. Meanwhile, sales related to Electro-hydraulic Tools trended firmly, and thorough implementation of a profitability-focused order-taking policy led to a significant improvement in segment profit to ¥2,628 million (up 11.0% year on year). The profit margin improved to 15.2%. In addition, with a deemed acquisition date of March 31, 2026, the company made Kofu Seibyo Co., Ltd. and KOHBYO (THAILAND) Co., Ltd. subsidiaries, recording a gain on negative goodwill of ¥284 million as extraordinary income (the allocation of acquisition cost is provisional).

Growth Drivers

  • Improved profit margin through continuation of a profitability-focused order-taking policy (achieving a segment profit margin of 15.2% in FY2026 (ending March 2026))
  • Continued solid demand from public investment centered on infrastructure development (public investment based on national resilience planning, etc.)
  • Enhanced micro components manufacturing capabilities and group synergies through the acquisition of Kofu Seibyo Co., Ltd. and KOHBYO (THAILAND) Co., Ltd. as subsidiaries
  • Promotion of "human capital development," "overall optimization," and "new business creation" under the new medium-term management plan "S.T.G Vision2026"
  • Continued firm sales of Electro-hydraulic Tools

Risks

  • Risk of construction delays and reduced completed construction revenue due to a shortage of skilled construction workers (the "2024 Problem")
  • Cost pressure from continued elevated steel prices
  • Rising raw material and energy costs due to the continuation of a weak yen trend
  • Risk of continued sluggish sales volumes of Post-installed Anchors (year-on-year decline again in FY2026 (ending March 2026))
  • Risk of changes in accounting treatment pending finalization of the acquisition cost allocation for the Kofu Seibyo group (currently provisional)
  • Risk of global political and economic turmoil spreading due to the foreign policy of the Trump administration in the United States and other factors
