Business
Osaka Yuka Kogyo Co., Ltd. was founded in 1949 as a contract processing company specializing exclusively in precision distillation. Its core technology utilizes slight differences in evaporation temperatures of chemical substances to separate and purify target substances from mixtures, providing high-purity purification services for the pharmaceutical, agrochemical, electronic materials, and aerospace industries. Major customers include Dow-Toray Co., Ltd. (net sales of ¥356 million, 30.3% of composition), Sumisho Chemical Co., Ltd. (¥186 million, 15.8%), ENEOS Corporation (¥141 million, 11.9%), and other major chemical and materials companies. Through its consolidated subsidiary Yuka Engineering Co., Ltd., the company also handles the design, sales, and maintenance of distillation equipment (Design, Sales, Technical Support) and filtration equipment, having built a system that provides integrated solutions from Contract Distillation Business through to plant sales.
Business Model
In the Contract Distillation Business, which accounts for approximately 93% of revenue, the company adopts a processing-fee model in which it receives raw materials from customers and refines and delivers them using its own distillation equipment. This has achieved a highly profitable structure with a segment profit margin of 42.5%. In the Plant Business, the company designs and sells distillation equipment and filtration equipment based on its own technology and test data, and generates ongoing revenue through maintenance services after delivery. A key differentiating factor is the ability to provide comprehensive support to customers from the R&D stage through to mass-production transition, by leveraging the technology and know-how of both businesses in combination.
Company Strengths
As a result of over 70 years of specialization in precision distillation since its founding in 1949, the company has accumulated advanced technical capabilities that enable it to accept orders that other companies cannot handle. In FY2025 (ending September 2025), the Contract Distillation Business segment achieved a profit margin of 42.5% (profit of ¥467 million), establishing a high-value-added model built on specialized focus.
In FY2025 (ending September 2025), transactions with Dow Toray Co., Ltd. expanded to ¥356 million (up 26.6% year-on-year), while Sumitomo Corporation Chemical Co., Ltd. (¥186 million) and ENEOS Corporation (¥141 million) newly emerged as major clients accounting for over 10% of sales, advancing the diversification of the customer portfolio.
As of the end of FY2025 (ending September 2025), total net assets stood at ¥1,647 million and total liabilities at ¥209 million, reflecting extremely low financial leverage, with interest-bearing debt at virtually zero. The company held cash and cash equivalents of ¥873 million, giving it a stable financial foundation capable of funding capital expenditure and business expansion through equity capital alone.
ENVALITH's Perspective
Performance Trend
The recovery trend has continued since bottoming out in FY2024 (ending September 2024) (revenue of ¥987 million, operating profit of ¥19 million). A sharp recovery followed in FY2025 (ending September 2025) (revenue of ¥1,178 million, operating profit of ¥139 million), and the first half of FY2026 (ending September 2026) showed substantial improvement, with revenue of ¥727 million (up 23.2% year on year), operating profit of ¥149 million (up 31.6% year on year), and profit attributable to owners of parent for the first half of ¥113 million (compared to a net loss of ¥34 million in the same period of the previous year). The net loss in the same period of the previous year was mainly due to one-off extraordinary losses, namely TOB-related expenses of ¥114 million and impairment losses of ¥9 million. In the current first half, revenue growth was driven by a concentration of equipment deliveries in the Plant Business, while the Contract Distillation Business declined 2.3% year on year due to a plateau in demand from the semiconductor and electronic materials sectors. As an external factor, raw material procurement risk and cost increases associated with the situation in Iran represent an uncertainty for the second half. The full-year forecast remains unchanged at revenue of ¥1,240 million and operating profit of ¥140 million (up 0.7% year on year).
Growth Strategy
Dual-axis growth strategy combining steady growth in Contract Distillation with the accumulation of a track record in the Plant Business
Inquiries related to resources and energy have remained consistently strong, and the company is working to deepen customer relationships in both Contract Processing and R&D Support. R&D Support expanded 21.0% year on year in the current interim period, with revenue accumulation progressing in high-value-added areas.
The company is promoting proprietary distillation equipment and wastewater treatment equipment through exhibitions and active public relations activities to acquire new customers. In the current interim period, it delivered one distillation unit and four wastewater treatment units, achieving a turn to profitability. It is also proceeding in parallel with building up recurring revenue through Maintenance & Consumables Sales.
The company merged its consolidated subsidiary Kaiko into Yuka Engineering through absorption, integrating the design, manufacturing, and maintenance functions of the Plant Business. Through organizational efficiency gains and strengthened technical collaboration, it aims to differentiate itself by providing seamless, end-to-end services in conjunction with the Contract Distillation Business.
In December 2025, the company acquired 197,000 shares for ¥461 million and retired 226,800 shares, significantly reducing the number of shares outstanding. It aims to improve earnings per share while continuing shareholder returns by maintaining an annual dividend of ¥46 (interim dividend of ¥23).
