Business
Toagosei Co., Ltd. was founded in 1942 and listed on the Tokyo Stock Exchange in 1949 as a comprehensive chemical manufacturer. The Group consists of the Company, 24 subsidiaries, and 11 affiliated companies, operating six segments: Basic Chemicals (Electrolytic Products, Acrylic Monomer), Polymer & Oligomer, Adhesive Materials ("Aron Alpha" brand), High-Performance Materials (High-Purity Inorganic Chemicals), Resin Processed Products (environmental infrastructure and nursing care products), and Other (trading and transportation). The Group has overseas operations in Singapore, Thailand, Vietnam, China, Taiwan, India, and the United States, and positions semiconductors, mobility, environmental infrastructure, and medical as focus areas. Consolidated net sales for FY2025 (ending December 2025) were ¥162,312 million.
Business Model
The Basic Chemicals Business (Electrolytic Products and Acrylic Monomer), accounting for 44.2% of net sales, serves as the earnings foundation, while the Polymer & Oligomer Business (22.3%), Resin Processed Products Business (17.4%), Adhesive Materials Business (8.4%), and High-Performance Materials Business (6.3%) form the high-value-added segments. The company adopts a make-to-forecast production system and continuously invests in R&D expenses (4% or more of net sales) to accumulate proprietary technology. The proportion of high-value-added product sales rose to 45.6% in FY2025 (ending March 2025), and the company is advancing the sophistication of its earnings structure by expanding sales of products for growth areas such as semiconductors and mobility.
Company Strengths
In 1960, the company became Japan's first to commercialize acrylic acid esters, and in 1963 began production of the instant adhesive "Aron Alpha," reflecting a long accumulation of proprietary technology. R&D expenses for FY2025 (ended December 2025) reached ¥6,708 million (approximately 4.1% of net sales), and the company continues to strengthen its development structure, including the opening of the Kawasaki Frontiers R&D Center and increases in research personnel.
The company operates manufacturing and sales bases in Singapore, Thailand, Vietnam, China (Zhangjiagang, Shanghai, Shenzhen, Zhuhai), Taiwan, India, and the United States. New bases were established in Vietnam in 2024 and India in 2025, accelerating expansion into emerging markets. Overseas sales reached ¥29.4 billion in FY2025 (expanded compared to the previous medium-term management plan).
The equity ratio stood at a high 74.3% at the end of FY2025 (ended December 2025), reflecting strong financial soundness, with operating cash flow secured at ¥22,294 million. The interest coverage ratio was an extremely high 128.9 times, indicating ample capacity to cover interest payments. The company has a financial foundation capable of funding its ¥59,000 million capital expenditure plan for the three years from 2026 to 2028 primarily through internal funds.
ENVALITH's Perspective
Performance Trend
Revenue for Q1 FY2026 (ending December 2026) (January-March) was ¥38,634 million (down 3.0% year on year), and operating profit was ¥3,206 million (down 4.7%). The Basic Chemicals Business saw a significant decline in revenue and profit due to the discontinuation of Acrylic Monomer sales and price declines, while the High-Performance Materials Business (expanding demand for AI and memory applications), Polymer Business (profitability improvement), and Resin Processed Products Business (infrastructure demand) saw profit increases. Ordinary profit was ¥3,201 million (up 0.2%), essentially flat. Net profit attributable to owners of the parent was ¥2,774 million (up 38.7%), but this was the result of extraordinary income of ¥1,216 million, including a gain on sale of fixed assets of ¥879 million, and the underlying strength of the core business has followed the flat trend seen over the past five fiscal periods. The full-year forecast remains unchanged at revenue of ¥167,000 million and operating profit of ¥14,500 million. As an external factor, the surge in raw material and fuel prices driven by the situation in the Middle East continues to be a factor pressuring earnings.
Growth Strategy
Focused investment in four priority segments and profitability correction aimed at achieving net sales of ¥180,000 million and an operating margin of 10% by 2028
Capturing expanding demand for AI-related semiconductors and memory, the company continues to invest in expanding production capacity for High-Purity Inorganic Chemicals. Operating profit for Q1 of FY2026 (ending December 2026) surged approximately threefold, up 200.7% year on year, and capital investment is being accelerated as a priority area under the new medium-term plan.
The company is promoting increased sales volume of Acrylic Polymer for automotive, pharmaceutical, and semiconductor applications, together with overall profitability correction. Operating profit for Q1 of FY2026 (ending December 2026) improved to ¥878 million (up 39.1% year on year), with improvement becoming evident. Expansion of sales channels leveraging the multi-site overseas structure in Thailand, Vietnam, and elsewhere is also continuing.
Following the dissolution of the US joint venture, price revisions led to higher sales in Instant Adhesive (Household Use), but operating profit for Q1 of FY2026 (ending December 2026) fell sharply to ¥25 million (down 83.3% year on year) due to increased fixed costs associated with sales promotion in the US. Expansion into emerging markets through the establishment of a new base in India continues as a medium- to long-term initiative.
Against a backdrop of demand for countermeasures against aging infrastructure, particularly related to sewerage systems, sales volume of Environmental Infrastructure System Products increased. Operating profit for Q1 of FY2026 (ending December 2026) was strong at ¥669 million (up 33.6% year on year). Under the new medium-term plan, the environmental infrastructure field is positioned as a priority area, with continued investment planned.
The company has implemented a review of its business portfolio, including the discontinuation of sales of certain Acrylic Monomer products. Electrolytic Products saw increased sales due to price pass-through of rising costs. In response to soaring raw material and fuel costs driven by the situation in the Middle East, the company is promoting alternative procurement, securing inventory, and optimizing production plans, prioritizing stable product supply above all else.
