Business Model
By internalizing everything from mold design and fabrication to precision press processing, plastic molding, and unit assembly, the company responds to customers' diverse specification requirements. Product sales revenue is recognized at the time of shipment, while mold sales are recorded at the time of customer acceptance. Capital expenditures are funded through retained earnings, and the company maintains a financial structure close to debt-free while pursuing continuous cost reduction and quality improvement.
Company Strengths
The company possesses proprietary mold technology, including composite processing that fuses drawing and forging techniques, higher precision shearing processing, and short-term development leveraging simulation. It invested ¥68 million in R&D, continuing to deepen its technology under a two-division structure covering market development and mold development. It has achieved competitive differentiation in large-scale molding and drawing processing.
In FY2026 (ending March 2026), sales to Sumitomo Wiring Systems amounted to ¥5,164 million (28.2% of net sales), and sales to Denso amounted to ¥2,309 million (12.6% of net sales), with these two major automotive parts manufacturers accounting for approximately 41% of net sales combined. Sales of production equipment and molds associated with the start of mass production of new vehicle models have also progressed favorably, and the company maintains deep business relationships with its customers.
As of the end of FY2026 (ending March 2026), net assets stood at ¥16,329 million, while total assets were ¥22,927 million against liabilities of only ¥6,598 million.

ENVALITH's Perspective
Performance Trend
Revenue expanded approximately 30% over five periods, from ¥14,093 million in FY2022 (ending March 2022) to ¥18,289 million in FY2026 (ending March 2026). FY2025 (ending March 2025) saw a slight decline in revenue and a sharp drop in profit, but FY2026 (ending March 2026) recovered strongly with revenue up 8.6% and operating profit up 39.6%, driven by strong HV vehicle sales, the start of mass production of new vehicle models, and progress in sales of production equipment molds for new Automotive-Related Products. Digital Home Appliance-Related Products (up 23.2% year on year) and Other Products (Electronic Components / Industrial Equipment-Related) (up 41.5% year on year) also contributed. However, the FY2027 (ending March 2027) forecast is conservative, projecting revenue of ¥17,800 million (down 2.7% year on year) and operating profit of ¥690 million (down 9.5% year on year), reflecting factored-in risks from US tariff policy and a slowdown in automobile production volumes. As an external factor, foreign exchange losses narrowed to ¥8 million in FY2026 (ending March 2026) from ¥35 million in the previous period, supporting ordinary profit.
Growth Strategy
Diversification of the earnings base through expanded orders for HEV, electrical equipment, and infrastructure applications, coupled with utilization of the Thai subsidiary
A strategy of actively capturing sales of production equipment and molds for new automotive-related products, driven by strong HV sales and the start of mass production of new vehicle models. In FY2026 (ending March 2026), automotive-related sales increased 9.0% year on year, demonstrating results, but FY2027 (ending March 2026) plans are conservative given an expected slowdown in automobile production volumes.
Promoting diversification to reduce dependence on the automotive sector through expansion of Digital Home Appliance-Related Products such as digital cameras (up 23.2% year on year in FY2026 (ending March 2026)) and Other Products (Electronic Components / Industrial Equipment-Related) (up 41.5% year on year). This functions as a hedge against automotive-related risk.
Continuing to expand sales into Asia and optimize production costs through the use of THAI SANKO CO.,LTD. The foreign currency translation adjustment account expanded to ¥747 million at the end of FY2026 (ending March 2026) (from ¥523 million in the prior fiscal year), suggesting an expansion in the scale of overseas operations.
Policy of building up the balance of investment securities to ¥2,149 million at the end of FY2026 (ending March 2026) (up ¥871 million year on year), enhancing financial stability. Financial income such as dividends received and interest on securities substantially boosts ordinary income relative to operating income (FY2026 (ending March 2026): operating income of ¥762 million → ordinary income of ¥906 million).
