Business

S.T.CORPORATION is a daily necessities manufacturer founded in 1946, offering a product lineup spanning 7 categories, including deodorizers/air fresheners (Air Care), mothballs/insect repellents (Clothing Care), dehumidifiers (Moisture Care), cat litter products (Pet Care), gloves (Hand Care), and body warmers (Thermo Care). The company owns highly recognized brands such as "Shu-Shu Power (Shoshu-Riki)," "Musheeda," "Dry Pet," and "Nyan-tomo Seiketsu Toilet," with domestic general consumers as its primary customer base. Production and sales are conducted across the group, including 8 subsidiaries and 1 affiliate, and the company also maintains overseas bases in Thailand, South Korea, and Taiwan. Net sales for FY2026 (ending March 2026) totaled ¥48,492 million. The company is listed on the Prime Market of the Tokyo Stock Exchange.

Business Model

Core products are manufactured at in-house plants (Saitama, Kyushu, Tochigi, etc.) and by outsourced partners, then sold to retailers through wholesalers such as PALTAC Corporation and Arata Corporation. The top two wholesale customers account for approximately 61% of net sales. The structure aims to restore the operating margin by combining the cultivation of high-value-added products (such as the Premium Aroma series) and gross margin improvement through price increases with cost containment via review of procurement sources. Annual R&D expenditure of ¥1,035 million is invested to maintain product differentiation through core technologies such as odor science.

Company Strengths

The Air Care category formed the company's largest category with FY2026 (ending March 2026) net sales of ¥21,602 million (44.5% of total company sales), with the "Shoshu-Riki" brand maintaining the No.1 market share. High-value-added products such as the "Shoshu-Riki Premium Aroma" series and the new product "Shoshu-Riki DeoPita for Toilets" grew, achieving a 2.3% year-on-year increase. The brand recognition built through years of market development is a unique asset that is difficult for competitors to imitate in a short period.

The company operates across seven categories—Air Care (Deodorizers & Air Fresheners), Clothing Care (Mothballs/Insect Repellents), Moisture Care (Dehumidifiers), Pet Care (Cat Litter Products), Home Care (Food Care, Cleaners, etc.), Thermo Care (Body Warmers), and Hand Care (Gloves)—diversifying dependence on any specific category. In FY2026 (ending March 2026), while Clothing Care, Moisture Care, and Thermo Care saw decreased sales, Air Care, Pet Care, Home Care, and Hand Care saw increased sales, and the overall portfolio secured net sales of ¥48,492 million (up 0.8% year on year).

At the end of FY2026 (ending March 2026), the equity ratio stood at 73.1% (up 2.1 percentage points year on year), with cash and cash equivalents of ¥10,119 million. Interest-bearing debt remained at only ¥549 million, maintaining virtually debt-free management. This high level of financial soundness underpins the company's capacity for growth investments such as M&A and capital expenditures, enabling agile business expansion such as the acquisition of the pet care business in June 2024 and the absorption-type merger with Chardan in September 2024.

ENVALITH's Perspective

Net income attributable to owners of parent for FY2026 (ending March 2026) decreased significantly to ¥1,615 million (down 43.0% year on year), mainly due to the fall-off of the ¥1,101 million gain on negative goodwill and ¥551 million gain on sale of fixed assets recorded in the previous fiscal year. Ordinary income improved to ¥2,416 million (up 16.0% year on year), indicating that underlying profitability actually improved, so the decline in net income should not be viewed with excessive pessimism. However, the forecast for net income of ¥1,800 million (up 11.5% year on year) for the next fiscal year does not assume a recurrence of extraordinary gains, and attention should be paid to the gap between this and the ordinary income forecast of ¥2,700 million.

Clothing Care (Mothballs/Insect Repellents) declined 2.7% year on year (¥6,650 million) due to market stagnation stemming from diversification of storage styles; Moisture Care (Dehumidifiers) declined 9.4% year on year (¥2,503 million) due to reduced store visibility from a dry rainy season, intense summer heat, and lingering heat; and Thermo Care (Body Warmers) declined 3.0% year on year (¥3,971 million) due to a warm winter and delayed product rollout, resulting in simultaneous revenue declines across three categories. These stem from external factors such as climate change and lifestyle shifts, leaving uncertainty regarding the recovery outlook for the next fiscal year. Attention should be paid to the structural concentration risk whereby overall company revenue growth depends on the growth of Air Care (Deodorizers & Air Fresheners) and Pet Care (Cat Litter Products).

The consolidated earnings forecast for FY2027 (ending March 2027) is net sales of ¥52,000 million (up 7.2% year on year), operating income of ¥2,500 million (up 25.8% year on year), ordinary income of ¥2,700 million (up 11.7% year on year), and net income of ¥1,800 million (up 11.5% year on year). This is a bullish plan anticipating revenue growth across all categories, but the risk of surging energy and raw material prices amid Middle East tensions has not been reflected in the earnings forecast. In addition, research and development expenses are set to expand to ¥1,035 million, up ¥140 million year on year, and the balance between cost increase pressures and the effects of revenue growth will be key to achieving the operating income target. Continued monitoring is also needed regarding the decline in the interest coverage ratio, from 573.9x in FY2022 (ended March 2022) to 76.6x in FY2026 (ended March 2026).

Growth Strategy

Under SMILE 2027, the company is pursuing growth led by Air Care (Deodorizers & Air Fresheners) and Pet Care (Cat Litter Products) while simultaneously advancing a company-wide profit structure reform.

Expanding the existing market through the enlargement of the "Shoshuriki Premium Aroma" series and the launch of new products such as "Shoshuriki DeoPita for Toilets." The company aims to expand market share by appealing to younger consumers through diverse media channels. In FY2026 (ending March 2026), sales increased 2.3% year on year to ¥21,602 million, and further growth is expected in the next fiscal year.

Centered on "Nyantomo Seiketsu Toilet," the company is launching new products such as "Deodorizing & Antibacterial Chips for Multiple Cats" and "Shoshu Professional Beads" to raise brand awareness and accelerate sales channel expansion. The business is being cultivated as a core category in the wellness domain, offering total wellness solutions for families and their pets. In FY2026 (ending March 2026), sales increased 5.1% year on year to ¥3,778 million.

The company is improving its cost structure through supplier reviews, loss reduction, and supply chain restructuring, building a system that recycles the resulting resources into growth investments. Through the absorption-type merger of S.T. Business Support Corporation (effective July 1, 2025), the company is restructuring its logistics and supply chain to improve operational efficiency and productivity.

As part of optimizing the business structure in the Hand Care (Gloves) category, the company has withdrawn from the hand care manufacturing business of its consolidated subsidiary S.T. (Thailand). Business structure improvement expenses of ¥50 million were already recorded in FY2026 (ending March 2026). Domestically, the company continues to expand sales of commercial-use gloves and to cultivate the new product "Family Vinyl Medium-Thick Life Design."

R&D expenses increased 15.6% year on year, from ¥895 million in FY2025 (ended March 2025) to ¥1,035 million in FY2026 (ended March 2026). The company continues strategic investment in capital expenditure, R&D, and human capital for its core categories, laying the foundation for sales growth through the continuous launch of new products.
