Business
Ishihara Sangyo Kaisha, Ltd., founded in 1920, is a diversified chemical manufacturer built on two core pillars: the Organic Chemicals Business, centered on Agrochemicals (Herbicides, Insecticides, Fungicides), veterinary pharmaceuticals, and pharmaceuticals; and the Inorganic Chemicals Business, centered on Titanium Dioxide, functional colorants, electronic materials, and fine chemicals. The Group comprises the Company together with 34 subsidiaries and 5 affiliated companies, supplying products to markets worldwide, including Europe, the Americas, and Asia. Its major customers span a wide range, including agricultural producers, agrochemical distributors, electronic component manufacturers, and cosmetics manufacturers, and it operates a manufacturing and sales network domestically and overseas, with the Yokkaichi Plant (Mie Prefecture) as its main production base.
Business Model
In the Organic Chemicals Business, agrochemicals and veterinary pharmaceuticals created at the company's own central research laboratory are registered in countries around the world and formulated and sold through regional subsidiaries in Europe, the Americas, and Asia (such as ISK BIOSCIENCES EUROPE N.V.). In the Inorganic Chemicals Business, functional colorants, electronic materials, and fine chemicals are manufactured based on titanium dioxide technology and sold directly or indirectly to electronic component, cosmetics, and paint manufacturers both domestically and internationally. With continued investment of ¥11,245 million in R&D expenses (FY2026, ending March 2026), this is a research and development-driven business model that continues to renew earnings through the commercialization of new agrochemicals and new functional materials.
Company Strengths
The Organic Chemicals Business achieved net sales of ¥82,619 million and an operating margin of 22.2% in FY2026 (ending March 2026). The company has established specialized sales subsidiaries in Europe, the Americas, and Asia, and has registered and launched growth-strategy agents such as the herbicide tolpyralate, insecticide cyclaniliprole, and fungicide isofetamid in multiple regions. The global rollout of proprietary in-house developed products has enabled the company to maintain a high profit margin.
In the Inorganic Chemicals Business, leveraging its long-standing titanium dioxide manufacturing technology, the company has developed high value-added products such as high-purity titanium dioxide for MLCCs, the bismuth sulfide black pigment "LUSHADE® BLACK," and fine copper particles. In September 2023, it established MF Material Co., Ltd., a joint venture with Murata Manufacturing, strengthening its business foundation in the electronic materials field.
R&D expenses for FY2026 (ending March 2026) totaled ¥11,245 million (¥10,062 million for the Organic Chemicals Business and ¥997 million for the Inorganic Chemicals Business). The company maintains a diverse pipeline, including the creation of new agrochemicals using cutting-edge methods such as AI-driven drug discovery, expansion of indications for the veterinary pharmaceutical PANOQUELL®, and development of biological products, driving continuous commercialization of new products.
ENVALITH's Perspective
Performance Trend
Net sales increased for five consecutive fiscal years, rising from ¥110,955 million in FY2022 (ended March 2022) to ¥154,897 million in FY2026 (ending March 2026). Operating profit fell to ¥8,631 million in FY2023 (ended March 2023) before reaching a record high of ¥19,077 million in FY2026 (ending March 2026). The improvement in FY2026 (ending March 2026) was driven by strong agrochemical sales in the Organic Chemicals Business, including weather-related factors in Europe (segment profit of ¥18,330 million, up ¥5.8 billion year-on-year), and the recording of foreign exchange gains of ¥2,145 million. Cost of sales decreased by ¥434 million year-on-year, improving the gross profit margin to 32.1% (from 27.2% in the previous period). On the other hand, for FY2027 (ending March 2027), a substantial decline in operating profit to ¥14,200 million (down 25.6% year-on-year) is forecast, due to the disappearance of the special European demand, increased joint development expenses for new agrochemical agents, higher R&D expenses associated with the delayed approval of PANOQUELL, and the impact of the fire at Fuji Titanium Industry's Kobe plant, among other factors. This leaves challenges regarding the sustainability of growth.
Growth Strategy
Advancing global agrochemical expansion, structural reform of the Inorganic Chemicals Business, and ROIC-focused management under Vision 2030 Stage II
Continuing to obtain and maintain agrochemical registrations in Europe, the Americas, and Asia, while accelerating market development of growth strategy products (herbicides, etc.). In FY2026 (ending March 2026), herbicides in the Americas, fungicides in Europe, and insecticides in Asia each grew, achieving Organic Chemicals Business net sales of ¥82,619 million (up ¥8.2619 billion year on year). Joint development of new agrochemical products with other companies is also being pursued.
Aiming for expanded sales following full approval in the US and rollout to major countries worldwide. At present, full approval is delayed, and R&D expenses are expected to increase. Once approval is obtained, this has significant potential to contribute to revenue diversification within the Organic Chemicals Business.
Shifting the portfolio from general-purpose Titanium Dioxide toward higher value-added products such as electronic component materials and functional colorants. In FY2026 (ending March 2026), domestic sales of electronic materials grew significantly, achieving Inorganic Chemicals Business segment profit of ¥4,972 million (up ¥3.3 billion year on year). However, the fire accident at Fuji Titanium Industry's Kobe Plant (April 2026) remains an operational risk.
The medium-term management plan "Vision 2030 Stage II" positions ROIC-focused management as a key priority to improve capital efficiency. In FY2026 (ending March 2026), ROE reached 13.7%, exceeding the target of 10% or more. An annual dividend of ¥120 (up ¥35 year on year) was implemented, with ¥130 planned for the next fiscal year. The policy of a DOE floor of 3% and a dividend payout ratio target of 40% continues.
