Business

Fine Sinter Co., Ltd., founded in 1950, is a specialized powder metallurgy manufacturer that develops three businesses—Automotive Sintering Business, Railway Sintering Business, and Hydraulic Equipment Products Business—centered on sintering technology, which hardens metal powder through compression and heating. The company maintains a global operating structure with six domestic and overseas manufacturing subsidiaries (in Thailand, the U.S., China, Indonesia, etc.), with Toyota Motor Corporation and Denso as its principal customers. The Automotive Sintering Business accounts for approximately 91% of net sales, while the Railway Sintering Business, which handles Contact Strips for Shinkansen and Brake Linings for Shinkansen (with a profit margin exceeding 27%), and the Hydraulic Equipment Products Business, which produces small hydraulic equipment for dental chairs (with a profit margin of approximately 24%), complement it as high-profitability pillars. The company is listed on both the Tokyo and Nagoya Stock Exchanges.

Business Model

The company adopts an integrated manufacture-to-direct-sales model covering metal powder forming, sintering, and finishing. In the Automotive Sintering Business, it pursues economies of scale through mass-production, made-to-order manufacturing, while in the railway and hydraulic equipment businesses it operates a high-margin business leveraging high technical barriers to entry and strong customer lock-in. In recent years, the company has been shifting from selling individual components toward higher-value-added unit products (integrated from design through production), aiming to upgrade its earnings structure. R&D expenses amounted to ¥596 million (FY2026 (ending March 2026)), funding continued development of Inverter Components for Hybrid Vehicles and next-generation magnetic material products.

Company Strengths

For Inverter Components for Hybrid Vehicles (Reactor Cores), the company added a mass-production line for a new product model, with production starting in FY2026 (ending March 2026). The line has reached a planned scale sufficient to cover 5.2 million HEV units, and the installation of mass-production equipment for high-value-added unit products handled in-house from design through production is also nearly complete. It can be confirmed that electrification-related products drove the increase in both revenue and profit in the Automotive Sintering Business.

The Railway Sintering Business, with Contact Strips for Shinkansen and Brake Linings for Shinkansen as its core products, achieved a segment profit margin of 27.1% in FY2026 (ending March 2026). While order levels remained at the same level as the previous fiscal year, cost improvements progressed, resulting in segment profit of ¥646 million, up 24.7% year on year. The core technology, which balances current collection performance and wear resistance, forms an entry barrier that is difficult for competitors to replicate in a short period.

The second Thai Fine Sinter plant began full-scale production in November 2024, and sales of drivetrain components have been trending favorably. Sales in the Automotive Sintering Business for FY2026 (ending March 2026) reached ¥41,895 million (up 8.9% year on year), contributing to the achievement of a record-high sales figure. The company has built a supply system with six locations globally, positioned close to customers' production sites.

ENVALITH's Perspective

FY2026 (ending March 2026) saw net sales of ¥46,206 million (up 8.2% year-on-year, a record high) and operating profit of ¥1,195 million (up 75.0% year-on-year), clearly indicating improved business earning power. However, as a result of recording an impairment loss on fixed assets of ¥2,191 million (AFS, Shiga, Yamashina plants, etc.) and an inventory valuation loss of ¥473 million as extraordinary losses in connection with the restructuring of global production bases, net loss attributable to owners of the parent expanded significantly to ¥2,414 million, compared to the previous period's loss of ¥207 million. While the impairment represents a positive step in structural reform, the scale and continuity of the losses require continued close monitoring.

At the Board of Directors meeting held on April 28, 2026, a resolution was passed to discontinue the business of AFS (Ohio, USA; capital of US$64,624 thousand; a wholly owned subsidiary of the Company), with plans to phase out operations and transfer them to other locations by the end of March 2028. AFS was a problem site that recorded an impairment loss exceeding ¥1,804 million in FY2026 (ending March 2026), and details of the additional losses and withdrawal costs associated with the business discontinuation are currently being scrutinized. The FY2027 (ending March 2027) earnings forecast (net sales of ¥44,500 million, operating profit of ¥1,200 million) partially reflects the impact of the AFS discontinuation, but uncertainty remains high.

The equity ratio at the end of FY2026 (ending March 2026) improved slightly to 30.9% (from 29.5% in the previous period), and cash flow from operating activities improved significantly to ¥4,759 million (from ¥814 million in the previous period). The balance of cash and cash equivalents at period-end also increased to ¥5,537 million (from ¥4,119 million in the previous period). On the other hand, the total of short-term and long-term borrowings remains at a high level of ¥17,318 million (short-term borrowings of ¥8,228 million + current portion of long-term borrowings due within one year of ¥3,650 million + long-term borrowings of ¥5,440 million), and uncertainty over U.S. trade policy and automotive electrification remains a key risk to medium-term performance.

Growth Strategy

Strengthening underlying earning power through production site restructuring, combined with focused investment in three growth areas: magnetic materials, railway, and hydraulics

The business of AFS (Ohio), a U.S. subsidiary that has continued to underperform, will be phased out by the end of March 2028, with production transferred to other sites within the group. Fixed cost reduction and improved asset efficiency aim to enhance medium- to long-term earning power and strengthen the financial structure.

As of May 30, 2025, additional equity in Jingmi Shaojie Hejin (Wuxi) Co., Ltd. (Precision Sintered Alloy (Wuxi) Co., Ltd.) was acquired, making it a wholly owned subsidiary. Capital surplus increased by ¥1,276 million. The residual value of fixed assets was also revised (from 10% to 1% of acquisition cost), establishing an asset management structure that better reflects actual conditions.

Achieved the start of production of new inverter components for hybrid vehicles (reactor cores, etc.). Under the medium-term management plan, magnetic materials are positioned, together with unit product handling, as a key growth area, with the aim of further enhancing added value and profit margins.

Management resources are being prioritized toward the highly profitable Railway Sintering Business (profit margin of 27.1%) and the Hydraulic Equipment Products Business (profit margin of 23.6%). Continued cost improvement for Shinkansen-related products and expansion of North American customers and new orders in the hydraulic business are being pursued to reduce dependence on the automotive business.

Continued efforts include optimizing sales prices for unprofitable products, passing on rising raw material and energy prices to sales prices, and reflecting prior-year raw material price fluctuations in pricing. The gross profit margin for FY2026 (ending March 2026) improved to 14.2% (13.5% in the previous fiscal year).
