Business
Sanko Gosei Ltd. is a plastics engineering company founded in 1944. The Group consists of 21 subsidiaries including the Company, with its main business being the manufacture and sale of plastic molded products (Parts for Information & Communication Equipment, automotive parts, and home appliance parts) and Molds for Plastic Molding. The Group operates in four segments—Japan, Europe, Asia, and North America—and has production and sales bases worldwide, including in the UK, Czech Republic, Thailand, Indonesia, China, India, the Philippines, Mexico, and the United States. Its main customers are automobile manufacturers, and in FY2025 (ended May 2025), sales in the vehicle segment amounted to ¥63,367 million, accounting for 69.6% of total sales.
Business Model
The company has built an integrated production system spanning product design, mold making, molding, painting, assembly, and labor-saving equipment production. Leveraging its proprietary mold technology, it secures orders for high-value-added molded products and ensures cost competitiveness through globally optimized production. Its revenue structure rests on two pillars: Molded Products (83.5% of net sales) and Molds (16.5% of net sales), forming an integrated upstream-downstream business model in which mold orders lead to continuous orders for molded products.
Company Strengths
In FY2025 (ended May 2025), the company achieved net sales of ¥91,101 million (down 2.9% year on year), while operating profit rose to ¥5,656 million (up 36.9% year on year) and net income attributable to owners of parent reached ¥3,857 million (up 47.6% year on year). The operating profit margin improved to 6.2% (up 1.8 points year on year), and ROE improved to 12.4% (up 3.0 points year on year), reflecting a notable qualitative improvement in the earnings structure.
The company has established a four-region structure comprising Japan (net sales of ¥30,210 million), Europe (¥12,110 million), Asia (¥29,654 million), and North America (¥19,125 million). Even as Europe and Asia trended toward production cuts, Japan and North America maintained revenue growth, and profit increased in all segments. This geographic diversification contributes to the stability of business performance.
The company is advancing a wide range of R&D initiatives, including plastic resource circulation technology development adopted by NEDO, processing technology for carbon fiber composite materials (CFRP and CFRTP), mold fabrication utilizing 3D printers, and development of proprietary molded product deformation simulation software. R&D expenses for FY2025 (ended May 2025) totaled ¥874 million. New product development is also underway through a capital and business alliance with Futaba Corporation.
ENVALITH's Perspective
Performance Trend
Revenue recovered from a slight decline in FY2025 (¥91,101 million) to ¥97,979 million in FY2026 (up 7.6% year on year), while operating income rose to ¥7,091 million (up 25.4% year on year), achieving improvement for the fifth consecutive fiscal year, with the operating margin rising to 7.2%. However, as ¥3,599 million in settlement-related expenses was recorded as an extraordinary loss, income before income taxes and other adjustments was limited to ¥2,607 million, and net income attributable to owners of parent fell sharply to ¥758 million (down 80.3% year on year). As an external factor, a gradual economic recovery driven by improving employment and income conditions provided a tailwind, while surging crude oil prices, rising prices in general, U.S. tariff policy, and rising long-term interest rates acted as headwinds. The North America segment recorded the highest growth rate in both revenue and profit, driving the overall increase in revenue and profit.
Growth Strategy
Aiming for sustainable profit growth through global expansion of sales of high-value-added products and molds, combined with strengthening of the earnings structure
The company is selectively strengthening orders for high-value-added products, primarily Vehicle Interior/Exterior Parts (Molded Products), and combining this with cost reduction activities to continuously improve profitability. The operating margin of 7.2% in FY2026 (ending May 2026) represents an improvement of 1.0 percentage point year on year, demonstrating the effect of these initiatives in the numbers.
In North America, property, plant and equipment increased significantly to ¥12,803 million (from ¥9,256 million in the previous period), while in Asia, ¥1,607 million was invested in fixed assets. The company aims to strengthen the earnings base in each region by capturing local demand and improving production efficiency. Investing cash flow expenditure in FY2026 (ending May 2026) was ¥6,481 million, up 22.0% year on year.
In August 2026, the company newly appointed an executive officer in charge of the Indian mold market, beginning full-scale deployment of mold technology into the rapidly growing Indian automotive market. Through global expansion of sales in the mold business, the company aims to build an order base of new customers and regions through synergy with the molded products business.
Reflecting on the sharp decline in net income for FY2026 due to the recording of ¥3,599 million in settlement-related expenses, the company aims to strengthen its management fundamentals, including legal risk management. For FY2027, a substantial recovery to net income of ¥4,500 million is projected, with the focus on demonstrating core business earning power once one-time expenses are excluded.
