Business

Toho Chemical Industry, founded in 1938, is a chemical manufacturer operating four segments: Surfactants, Resins, Chemical Products, and Specialty Chemicals. Multi-application surfactants such as Cosmetic Raw Materials, Agrochemical Adjuvants, and Civil Engineering & Construction Chemicals constitute the company's largest business, accounting for approximately 47.5% of net sales, followed by Specialty Chemicals—which includes photosensitive Resins for Fine Processing used in semiconductors—at approximately 30.9%. In addition to four domestic plants (Oppama, Chiba, Kashima, and Yokkaichi), the company has production and sales bases in China (Shanghai and Guangdong Province) and Thailand, building a global manufacturing and sales network. Major customers span a wide range of industries, including semiconductor and electronic component manufacturers, construction and civil engineering contractors, and agrochemical and cosmetics manufacturers. The company's management policy is to be "a mid-tier chemical manufacturer of excellence centered on fine chemicals that shine even though small."

Business Model

A vertically integrated model in which technology development originating from the company's own research laboratories (Oppama and Chiba) leads to the manufacture of functional chemicals at domestic and overseas company-owned plants, which are then sold directly to various industries. The company invests 3.5% of net sales (¥1,885 million) in R&D expenses, seeking differentiation through the continuous development of high-value-added products. It pursues improved profitability by combining cost competitiveness secured through its Chinese subsidiary with a focus on producing high-value-added products at domestic plants.

Company Strengths

Since installing electronic information materials manufacturing equipment at the Chiba Plant in 1999, the company has continuously expanded facilities in 2008, 2012, 2017, 2019, and 2021. Specialty Chemicals sales in FY2026 (ending March 2026) reached ¥16,558 million, up 5.0% year on year, and the company has also begun development of photosensitive fine processing resins for next-generation semiconductors.

The company offers Surfactants for a wide range of applications including Cosmetic Raw Materials, Agrochemical Adjuvants, Civil Engineering & Construction Chemicals, Textile Auxiliaries, and Paper & Pulp Chemicals. In FY2026 (ending March 2026), Surfactants sales were ¥25,460 million, accounting for approximately 47.5% of total company sales. Despite a 3.2% year-on-year decrease in sales, changes in the sales mix (a shift toward higher-margin products) allowed segment profit to increase by ¥54 million year on year to ¥791 million.

The company has production and sales bases in Shanghai, Guangdong Province (Huaiji and Huizhou), and Thailand. In FY2026 (ending March 2026), the expansion of pressurized reaction equipment at Toho Chemical (Shanghai) Co., Ltd. was completed, with operations starting in March 2026. The two Shanghai bases combined have recorded operating profit of around ¥400 million for two consecutive fiscal years, and sales to overseas markets continue to expand steadily.

ENVALITH's Perspective

Consolidated operating profit for FY2026 (ending March 2026) was ¥2,088 million (up 15.0% year on year), returning to the ¥2 billion range for the first time in 6 fiscal periods. However, as total income taxes increased from ¥425 million to ¥550 million, profit attributable to owners of parent turned to a slight decline, coming in at ¥1,527 million (down 1.0% year on year). Net sales were nearly flat (up 0.0%), and the profit increase was mainly driven by improvement in sales mix and improved profitability in Chemical Products, indicating that top-line growth remains limited.

The effective blockade of the Strait of Hormuz resulting from the military conflict between the US/Israel and Iran at the end of February 2026 has led to difficulty in procuring petrochemical raw materials and a sharp rise in prices. While the impact on the current period's results is said to be minor, the earnings forecast for the next fiscal period (FY2027, ending March 2027) has been left undetermined, described as "reasonably difficult to calculate." Both risks—reduced production volume due to raw material shortages and deteriorating profitability due to higher raw material costs—have become apparent, and investors should closely monitor the situation, including the risk of delays in earnings disclosure.

The equity ratio improved for the fourth consecutive fiscal period, rising from 26.0% in FY2023 (ended March 2023) to 33.9% in FY2026 (ended March 2026), reflecting continued strengthening of the financial structure. Meanwhile, interest-bearing debt (total of bonds and borrowings) remains at a high level, though the ratio of cash flow to interest-bearing debt improved to 6.2 years (from 8.1 years in the prior period) and the interest coverage ratio improved to 10.0x (from 8.4x in the prior period), both showing an improving trend. The structure in which capital expenditure (acquisition of property, plant and equipment of ¥4,391 million) consumes almost all of operating cash flow (¥4,400 million) continues, and the capacity to generate free cash flow will determine the sustainability of the financial improvement.

Growth Strategy

Establishing electronic information materials as a core business and upgrading the earnings structure through utilization of the Shanghai base

Toho Chemical (Shanghai) Co., Ltd. is currently carrying out building reinforcement work in preparation for the expansion of pressurized reaction equipment. In FY2026 (ending March 2026), the temporary suspension of some equipment operations due to the construction work resulted in a decrease in operating profit at the Shanghai subsidiary compared with the previous fiscal year; however, upon completion, the company aims to significantly expand supply capacity and increase sales of electronic information materials. Expenditures for the acquisition of tangible fixed assets increased substantially to ¥4,391 million from ¥2,846 million in the previous fiscal year, reflecting an ongoing investment phase.

In the Surfactants segment, while net sales decreased by ¥847 million year on year, segment profit increased by ¥54 million year on year to ¥791 million, driven by margin improvement resulting from changes in the sales mix, among other factors. In the Chemical Products segment as well, improved profitability of Petroleum Additives led to a ¥223 million year-on-year increase in profit to ¥302 million. The portfolio shift from general-purpose products to higher value-added products is contributing to margin improvement.

Following the blockade of the Strait of Hormuz at the end of February 2026, the company is reviewing its production plans in light of the raw material procurement situation, revising sales plans, and reviewing its profit and loss plans to incorporate rising raw material costs and the pass-through of these costs to selling prices. In the Specialty Chemicals segment, delays in passing on the increase in the cost of imported raw materials caused by the yen's depreciation have led to a temporary decline in profit margins, making faster pass-through of price increases a key challenge.
