Business

Rinnai Corporation is a heat appliance specialist manufacturer founded in 1920, engaged in manufacturing and sales across 7 regions including Japan, the United States, Australia, China, South Korea, and Indonesia, centered on water heating equipment, kitchen equipment, and air conditioning equipment. The group as a whole, including 50 consolidated subsidiaries and 2 affiliated companies, recorded net sales of ¥470,392 million (FY2026 (ending March 2026)). Domestically, the company's main customers are city gas companies, homebuilders, and pipe and building materials distributors, while overseas it follows a policy of "business rooted in local communities," with manufacturing and sales conducted basically through local subsidiaries. Guided by the founding philosophy that "quality is our life," the company supplies high-value-added products globally under the themes of "heat and living" and "health and living."

Business Model

In Japan, the company sells directly to city gas companies, homebuilders, and others (with some OEM supply), while overseas, local subsidiaries handle manufacturing and sales under a locally-produced, locally-consumed model. The company has a structure that enhances profitability through a combination of product mix improvement—raising the sales ratio of high-value-added products such as Gas Clothes Dryers, Air Bubble Products, and hybrid water heaters—and cost reduction activities through local development and production. Research and development expenses amounted to ¥15,939 million (FY2026 (ending March 2026)), continuously strengthening core technologies in combustion, heat transfer, IoT, and heat pumps.

Company Strengths

Water heaters equipped with Air Bubble Technology surpassed cumulative sales of 150,000 units as of September 2025. The company has expanded deployment by installing Ultra Fine Bubble technology in commercial water heaters for the first time. With 2,267 patents held (as of end-March 2026) and 129 patents registered during the fiscal year under review, the company's extensive technological accumulation has enabled product differentiation that is difficult for competitors to replicate in the short term.

Starting with entry into Australia in 1971, the company established local subsidiaries in South Korea, the United States, Indonesia, China, and other countries, building a global production and sales system over more than 50 years. The overseas sales ratio reached approximately 56% in FY2026 (ending March 2026), and the company has established a strong sales foundation in each region, including a high market share and strong brand recognition in the local gas stove market in Indonesia.

As of the end of FY2026 (ending March 2026), the equity ratio stood at 67.3%, and interest-bearing debt was ¥18,746 million, reflecting a high degree of financial soundness. The company held cash and cash equivalents of ¥134,506 million and secured operating cash flow of ¥49,298 million. It possesses the financial strength to fund both shareholder returns, based on a policy of progressive dividends, and growth investments from its own resources.

ENVALITH's Perspective

The company achieved the revenue and profit targets of its previous mid-term plan in FY2026 (ending March 2026), and under the new plan "accelerate 2030" it has set FY2030 targets of consolidated revenue of ¥620,000 million, operating profit of ¥70,000 million, an operating margin of 11.3%, ROE of 10%, and ROIC of 15%. The forecast for FY2027 (ending March 2027) calls for revenue of ¥500,000 million (up 6.3% year on year) and operating profit of ¥50,500 million (down 0.1% year on year), implying flat profit, and the fact that tariff impacts and Middle East risk have not been factored into the earnings forecast warrants close attention as a downside risk.

The China segment recorded revenue of ¥60,682 million (down 11.5% year on year) and operating profit of ¥9,415 million (down 6.7% year on year) in FY2026 (ending March 2026), marking a second consecutive year of declining revenue and profit. The chilling of consumer sentiment amid the economic slowdown has continued, and the company has indicated that consumption is expected to remain sluggish due to economic stagnation in FY2027 (ending March 2027) as well. On the other hand, the operating margin has been maintained at around 15%, and the high-profitability structure achieved through agile production adjustments and cost control deserves recognition. Reducing dependence on China and offsetting this through other regions remain challenges.

As an external factor, the tightening of carbon neutrality regulations centered on North America, Oceania, and Europe serves as a tailwind boosting demand for Heat Pump Water Heaters, while U.S. trade policy (tariffs) pushed down the United States segment's operating profit by 12.8% year on year in FY2026 (ending March 2026). The company has not factored the impact of the Middle East situation into its FY2027 (ending March 2027) forecast, and the downside risk to earnings remains high should geopolitical risks materialize in the form of rising parts procurement costs. The pace of expanding the electrified product lineup will be a key factor determining differentiation from competitors.

Growth Strategy

Under the new mid-term management plan "accelerate 2030," the company is accelerating the expansion of electrification products, the creation of new value, and the development of growth markets.

In anticipation of energy policies in various countries, the company is making a full-scale entry into the electrification market by leveraging its core technologies and sales network cultivated in gas equipment, centered on Heat Pump Water Heaters. In Australia, sales of Heat Pump Water Heaters were strong in FY2026 (ending March 2026), achieving a 20.3% year-on-year increase in revenue. In North America, the company is also focusing on expanding its electrification product lineup and sales. FY2030 target: 1.5x increase in sales of quality-of-life-enhancing products and environmentally contributing products (versus FY2025).

In October 2025, the company made MT Industrial Corporation (sales, installation, and maintenance of water heaters and kitchen equipment for the Latin American market) a subsidiary at an acquisition cost of ¥11,176 million, promoting the expansion of business scale in the Latin American region. Goodwill of ¥4,518 million (amortized equally over 9 years) was recorded. The estimated impact on sales, had the company been consolidated from the beginning of the fiscal year, is calculated at ¥11,140 million. The company will continue to leverage existing technologies and sales channels in growth markets where population and income growth are expected.

In Japan, the company continues to expand sales of "ECO ONE," Gas Clothes Dryers, and Air Bubble Products (Ultra Fine Bubble / Micro Bubble), along with strategic new product launches. In China, the company maintains a high profit margin (approximately 15% level) through agile production adjustments, fixed cost management, and productivity improvements. In South Korea, operating profit increased 17.7% year-on-year due to growth in Boiler Equipment sales. FY2030 target: Consolidated operating margin of 11.3% (improved from 10.7% achieved in FY2026, ending March 2026).

In FY2026 (ending March 2026, the final year of the plan), the company achieved net sales of ¥470,392 million and operating profit of ¥50,531 million, meeting both the sales and profit targets set forth in the mid-term management plan as planned. The growth of high-value-added products, the effects of increased revenue, and cost reduction activities all contributed to this success.
