Business

SUMINOE Co., Ltd. (formerly Sumitomo Textile Co., Ltd.) is a comprehensive interior materials manufacturer founded in 1930, forming a group with 29 consolidated subsidiaries and 1 affiliated company. Its two main pillars are the Interior Business (net sales of ¥38,264 million), which handles carpets, curtains, wallpaper, and other products, and the Automotive & Vehicle Interior Business (net sales of ¥63,478 million), which manufactures and sells interior materials for automobiles, railways, and buses both domestically and internationally. The company has production and sales bases in the United States, Mexico, China, Thailand, Vietnam, Indonesia, and India, building a global supply system. In December 2024, the company changed its name to "SUMINOE Co., Ltd." and is promoting full-scale overseas expansion and strengthening of its non-fiber business areas. Its main customers include interior demand from office buildings, commercial facilities, and residences, as well as Japanese and foreign automakers, and public transportation operators such as railway and bus companies.

Business Model

The group vertically integrates manufacturing (Suminoe Techno Co., Ltd., etc.), sales (Suminoe Interior Products Co., Ltd., etc.), logistics (Suminoe Logistics Co., Ltd.), and installation (CPO Co., Ltd.) within the group, providing consistent support from product planning and development through to delivery. Automotive interior materials are mainly supplied BtoB to domestic and overseas automakers, with local production at overseas bases diversifying foreign exchange risk while securing cost competitiveness. In the Interior Business, the company is pursuing profitability improvement through price revisions and higher value-added offerings through the Space Design Business (CPO Co., Ltd.). R&D expenses amounted to ¥1,115 million (up 5.3% year on year), continuing efforts to differentiate environmental and functional products.

Company Strengths

"ECOS" (mass production began in 2011) is a horizontally circulating recyclable tile carpet that promotes the use of recycled materials and CO2 reduction. In FY2025 (ending May 2025), the number of delivered projects for office buildings increased 4.1% year on year, earning high acclaim both domestically and internationally. Riding the tailwind of tightening environmental regulations, it functions as a key axis for differentiation from competitors.

The company holds production and sales bases in the United States, Mexico, China, Thailand, Vietnam, Indonesia, and India. In November 2024, it established a new base in Mexico for seat skin laminate processing. The Automotive & Vehicle Interior Business generated net sales of ¥63,478 million, forming the largest segment within the group, and serves as a profit base earning segment profit of ¥4,094 million.

The group encompasses manufacturing (Suminoe Techno Co., Ltd.), sales (Suminoe Interior Products Co., Ltd., Suminoe Teijin Techno Co., Ltd.), installation (CPO Co., Ltd.), logistics (Suminoe Logistics Co., Ltd.), and testing/inspection (Kansai Laboratory Co., Ltd.), building a system capable of handling everything from product planning to delivery and quality assurance in an integrated manner. The company is listed on the Prime Market of the Tokyo Stock Exchange.

ENVALITH's Perspective

Operating profit for FY2026 (ending March 2026, note: source states May) was ¥2,369 million, down 21.1% year on year. The main cause was that production system development at the Mexico synthetic leather plant failed to keep pace with an increase in new orders, resulting in lower production efficiency. The company itself acknowledges that improvement activities, including technical support, did not produce results, and has set "stabilization of the mass-production system at the North/Central America base" as the top priority issue for FY2027 as well. As an external factor, uncertainty over US trade policy is causing automakers to change their production plans, and the timing of improvement remains uncertain.

Net loss attributable to owners of the parent for the fiscal year was ¥340 million (versus profit of ¥669 million in the previous period). The breakdown consists of the disappearance of the gain on sale of investment securities (¥383 million) recorded in the prior period, the recording of income tax adjustment (¥923 million) associated with the write-down of deferred tax assets, and an increase in profit attributable to non-controlling interests (¥833 million), which overlapped in the same period. Ordinary profit improved to ¥2,764 million, up 10.0% year on year, indicating that the net loss was mainly driven by one-off tax and extraordinary income/loss factors rather than a structural deterioration in earnings. However, the write-down of deferred tax assets also occurred on a non-consolidated basis, requiring a cautious assessment of taxable income outlook.

The company forecasts net sales of ¥106,500 million (down 1.1% year on year), operating profit of ¥3,500 million (up 47.7%), and net profit attributable to owners of the parent of ¥1,450 million for FY2027. While a slight decline in sales is expected, a significant profit recovery is assumed, premised on earnings improvement through strengthened production management, quality control, and local management systems at the Mexico site. Improved profitability in the Interior Business (segment profit margin of 3.7% in FY2026) and continued inbound demand are tailwinds, but risks from US trade policy and rising raw material and energy costs due to yen depreciation remain sources of uncertainty regarding plan achievement.

Growth Strategy

In FY2027 (ending May 2027), the final year of STEP II, the Company will pursue profitability recovery and margin improvement as its top priorities

Strengthening production management, quality control, and local management systems at the Mexico synthetic leather plant to build a stable earnings foundation capable of responding to increased new orders. In FY2026 (ending May 2026), improvement activities were advanced but did not yet produce results, making FY2027 (ending May 2027) a critical turning point.

Promoting mass-production operations for automotive carpets and car mats at the Vietnam plant, and improving profitability through reorganization of the production system. This contributed to the Functional Materials Business turning profitable in FY2026 (ending May 2026) (segment profit of ¥54 million). The Company will continue strengthening the globally optimized supply system.

With the launch of the Custom Order Rug Series "Epilogue" targeting the mid-to-high-end segment, the lineup covering the mid-to-high-end segment—together with "itten" and "RĒI"—has been completed. The Company is promoting greater sales of environmentally friendly products centered on "ECOS®" and expanding orders for large-scale projects in the Space Design Business (CPO Co., Ltd.) (+12.5% year on year), driving improved recognition of the SUMINOE brand.

Newly launched spring/summer items such as cooling mats to diversify the seasonal concentration risk centered on Hot Carpet (Fiber-Based Heating Products). In FY2027 (ending May 2027), the Company will focus on securing orders and expanding sales channels for these items, while actively promoting proposal-based development sales that leverage stronger collaboration with other businesses to expand the Group's proprietary materials and technologies into new industries.

Strengthening the capability to propose total interior space design encompassing not only seat skin materials but also flooring materials and curtains. The Company is advancing the development of products that meet the growing needs of railway operators for enhanced safety and disaster-prevention measures, steadily capturing the recovery in demand for railway renewal work that had been postponed due to the COVID-19 pandemic. In FY2026 (ending May 2026), sales for both railway and bus applications exceeded the previous year's levels.
