Business
Toho Acetylene, founded in 1955, is an industrial gas specialist group comprising the Company, 15 consolidated subsidiaries, 3 equity-method affiliates, and others. In its core Gas-Related Business, the group manufactures and sells Dissolved Acetylene, Industrial Gases (Oxygen, Nitrogen, Argon), Hydrogen Gas, and Liquefied Petroleum Gas (LPG), supplying industrial, medical, and household customers through a network of affiliated companies with a strong sales foundation in Tohoku, Hokkaido, and Kanto. In addition, the group operates the Espuma-Related Business, which handles Espuma gas for restaurants and Food-Related Equipment; the Instruments & Equipment Business, covering Welding Materials and Welding & Cutting Equipment; the Automotive Equipment-Related Business; the Ice Machine-Related Business, which is responsible for the design and installation of Ice-Making & Refrigeration Machinery; and Other businesses such as construction work and medical equipment, thereby building a diversified business portfolio centered on industrial gas.
Business Model
The company combines production at its own factories (Tagajo Plant, Toho Sakata Hydrogen, etc.) with external procurement, supplying customers and distributors directly through branches, sales offices, and affiliated companies in the Tohoku, Hokkaido, and Kanto regions. The Gas-Related Business, accounting for approximately 60% of net sales, serves as the core business, while the Espuma-Related Business (operating margin of 29.2%) complements earnings as a high-profitability niche. Capital expenditures are funded mainly from internal resources, and liquidity on hand is ample, with cash and cash equivalents of ¥9,443 million against interest-bearing debt of ¥3,749 million.
Company Strengths
As sales companies, the Group has Toso Co., Ltd., Toho Co., Ltd., Shonai Gas Co., Ltd., Taihei Yozai Co., Ltd., Toho Iwate Co., Ltd., Toho Fukushima Co., Ltd., Toho Hokkaido Co., Ltd. and others, operating branches and sales offices across the Tohoku, Hokkaido, and Kanto regions. This community-based, multi-layered sales network, which is difficult for competitors to replicate in a short period of time, forms a stable customer base.
The Espuma-Related Business, centered on Nitrous Oxide for Food Additives, achieved net sales of ¥1,787 million and operating income of ¥521 million (operating margin of 29.2%) in FY2026 (ending March 2026). A nationwide sales network based in the Tokyo and Osaka branch offices, together with proprietary food-grade gas filling technology, forms a barrier to entry and lifts the profitability of the Group as a whole.
As of the end of FY2026 (ending March 2026), cash and cash equivalents stood at ¥9,443 million against interest-bearing debt (including borrowings and lease obligations) of ¥3,749 million. With net assets of ¥21,318 million, and under a capital expenditure policy centered primarily on internal funds, the Group is positioned to execute growth investments, such as the installation of new hydrogen generation equipment (capital expenditure of ¥1,527 million), while maintaining financial soundness.
ENVALITH's Perspective
Performance Trend
Revenue was ¥34,576 million (down 0.7% year on year), operating profit was ¥1,900 million (down 0.8%), ordinary profit was ¥2,109 million (down 2.8%), and profit attributable to owners of parent was ¥1,287 million (roughly flat year on year). Following a peak in FY2024 (ended March 2024), the company posted declines in both revenue and profit for two consecutive periods. External factors—falling selling prices due to fluctuations in LPG import prices, the disappearance of spot demand for oxygen and nitrogen, and reduced demand for welding materials for the construction industry—weighed on revenue. On the other hand, the absence of the large-scale periodic maintenance at the Tagajo Plant that took place in the previous period reduced cost of sales, leading to an increase in gross profit (from ¥10,974 million to ¥11,242 million); however, higher personnel and transportation costs pushed up SG&A expenses (from ¥9,059 million to ¥9,342 million), squeezing operating profit. The one bright spot was an increase in large-scale projects in the Ice Machine-Related Business. The forecast for FY2027 (ending March 2027) calls for revenue of ¥35,000 million (up 1.2%) and operating profit of ¥1,900 million (flat), indicating only limited recovery momentum.
Growth Strategy
Advancing capacity expansion in hydrogen and food-use gases along with profitability improvement under the new medium-term management plan
A new hydrogen generation unit was installed at the Tagajo Plant and began operation from FY2026 (ending March 2026). The company is strengthening hydrogen supply capacity, primarily for quartz processing applications, aiming to capture industrial hydrogen demand. This has been a major factor behind the increase in tangible fixed assets (up ¥763 million year on year), with the focus going forward on recouping the capital investment.
Leveraging the highly profitable position of the Espuma-Related Business, the company is constructing a new filling plant for food additive gas. Construction is proceeding with completion targeted within FY2026, after which increased supply capacity and expanded sales channels are expected to drive sales growth.
Following the conclusion of the previous medium-term management plan (FY2022–FY2025), which ended without achieving its numerical targets, the company plans to announce a new medium-term management plan in June 2026. The plan's pillars are stated to be improving productivity and strengthening functions in core businesses, accelerating the development of growth businesses, and practicing human capital management and sustainability management.
In the design and installation business for ice-making and refrigeration machinery for fishery cooperatives and food manufacturers, both sales and operating profit increased 54.7% year on year in FY2026 (ending March 2026), driven by an increase in large-scale projects. The company continues to develop new customers in the chemical industry, food processing, and leisure industry sectors, aiming for stable order acquisition.
