Business
Shin-Etsu Chemical Co., Ltd., founded in 1926, is a chemical materials manufacturer operating four segments: Electronics Materials, which handles Semiconductor Silicon (Silicon Wafers), Photoresist / Mask Blanks, and Rare Earth Magnets (for Electronics Industry / General Use); Living Environment Base Materials, centered on Polyvinyl Chloride (PVC) Resin and Caustic Soda; Functional Materials, including Silicone and Cellulose Derivatives; and Processing, Trading & Technical Services, covering resin processing and engineering. The company has 134 subsidiaries and 11 affiliated companies in Japan and overseas, and is a global enterprise with production and sales bases in North America, Europe, and Asia. It supplies products to a broad range of customers, from the semiconductor industry to daily living infrastructure, fulfilling its role as an "essential supplier."
Business Model
Leveraging in-house developed materials technology, the company manufactures and sells high-quality products across the semiconductor, chemical, and functional materials fields. Electronics Materials (operating margin of 33.9%) serves as the earnings pillar, while Living Environment Base Materials (16.8%) and Functional Materials (22.3%) supplement stable earnings. Capital expenditures are funded mainly through internal resources, with total capital expenditure for FY2026 (ending March 2026) at ¥339,706 million. R&D expenses of ¥77,819 million are invested to continue maintaining and expanding technological superiority.
Company Strengths
In FY2026 (ending March 2026), the Electronics Materials business posted net sales of ¥1,015,765 million and an operating margin of 33.9%, a high level. EUV photoresist has already transitioned to mass production for the 2nm generation, with development of next-generation process materials for 1.4nm and below also underway. The product portfolio as a comprehensive advanced electronics materials manufacturer capable of integrated supply of semiconductor silicon wafers, mask blanks, synthetic quartz, and other materials forms a competitive advantage.
The North American vinyl chloride business, centered on Shin-Etsu PVC (Shintech, USA), achieved vertical integration of raw materials by realizing in-house ethylene production in 2020. A new $3.4 billion investment in a raw material manufacturing plant (scheduled for completion by the end of 2030) is also underway. By leveraging a multi-layered sales network spanning North America, Asia, and Europe, the company has built a system capable of optimal sales execution even during periods of market softening.
In FY2026 (ending March 2026), the equity ratio stood at 78.7%, and operating cash flow secured was ¥712,651 million. The total of cash and deposits plus securities (including negotiable certificates of deposit) within current assets was ¥1,667,096 million, indicating high liquidity. The financial capacity to simultaneously execute capital expenditures of ¥339,706 million, treasury stock repurchases of ¥500,006 million, and dividends of ¥203,162 million enables the company to pursue both growth investment and shareholder returns.
ENVALITH's Perspective
Performance Trend
Revenue was roughly flat at ¥2,573,969 million (+0.5% year on year), but operating profit declined to ¥635,204 million (-14.4%) and profit attributable to owners of parent fell to ¥474,459 million (-11.2%), marking the second consecutive year of profit decline. This represents a decline of approximately 36% over three years from the FY2023 (ending March 2023) peak (operating profit of ¥998,202 million). The main causes of the profit decline were deterioration in market conditions for Living Environment Base Materials (sluggish Asian prices for polyvinyl chloride and softening North American demand in the second half) and rising energy and raw material costs stemming from the situation in the Middle East. Electronics Materials achieved higher revenue and profit on the back of expanding AI-related demand, but this was insufficient to offset the sharp drop in operating profit for Living Environment Base Materials (-43%). Operating cash flow remained at a high level of ¥712,651 million, but investing cash flow expanded to -¥544,806 million due to a net increase in time deposits and expanded capital expenditure, causing the cash and cash equivalents balance at fiscal year-end to decline sharply to ¥562,089 million (from ¥882,736 million at the previous fiscal year-end).
Growth Strategy
Pursuing sustainable growth through two pillars: capturing semiconductor/AI-related demand and expanding the scale of Living Environment Base Materials
The Isesaki Plant (exposure materials) began operations during FY2026 (ending March 2026), expanding supply capacity for photoresist and other products. The company is capturing AI and data center-related demand in Semiconductor Silicon (Silicon Wafers), Mask Blanks, and other areas, thereby strengthening its function as a comprehensive advanced electronics materials manufacturer. Capital expenditure for Electronics Materials in FY2026 (ending March 2026) is ¥212,300 million, the largest among all segments.
Shintech Inc. of the United States is investing $3.4 billion to expand its raw material manufacturing plant for Polyvinyl Chloride (PVC) Resin, strengthening vertical integration and cost competitiveness in North America. This is a long-term project targeting completion by the end of 2030, aimed at boosting the earnings base of Living Environment Base Materials over the medium to long term. The investment was announced during FY2026 (ending March 2026).
The company is promoting expansion of Silicone for electrical and electronic applications (for communications and AI) and cellulose products for formulation use. Development of new products such as recyclable thermoplastic silicone continues as well. In FY2026 (ending March 2026), despite a slight decline in net sales, operating income increased slightly (¥100.9 billion, +1%), showing early signs of profitability improvement, with price increase efforts also underway.
In April 2025, the company resolved to conduct a share buyback of up to 200 million shares and ¥500.0 billion, acquiring ¥500,006 million during FY2026 (ending March 2026). An additional buyback of ¥250.0 billion was subsequently announced. While maintaining an annual dividend of ¥106 per share (payout ratio of 41.9%), the company intends to continue stable dividends with a medium- to long-term payout ratio target of around 40%.
Even amid an uncertain environment where earnings forecasts remain undetermined, the company plans capital expenditure of ¥350,000 million for FY2027 (ending March 2027) (an increase from the previous fiscal year's actual results), continuing capital investment aimed at medium- to long-term growth. The company is proactively expanding supply capacity across each segment, including the start of operations at a new plant for Semiconductor Wafer-related Containers.
