RIKEN KEIKI, a pioneer in gas detection equipment, reported record net sales of 55,212 million yen for the fiscal year ended March 31, 2026 (labeled “FY2025” in the company’s English-language financial results briefing), up 12.6% year on year, and record operating profit of 12,425 million yen, up from 10,642 million yen in FY2024. The company attributes the growth to a higher volume of renewal and construction projects domestically as well as increased overseas sales to North America and China. Both net sales and operating profit exceeded the full-year forecast, and the annual dividend was raised to 55 yen per share, up 10 yen from the previous fiscal year. For the fiscal year ending March 31, 2027, the company forecasts continued net sales growth driven by semiconductor-industry demand tied to generative AI and data centers, while operating profit is expected to decline temporarily due to organizational investment and a pricing strategy aimed at expanding global market share.
Consolidated Results (Full-Year Actual)
Net sales rose 12.6% year on year to 55,212 million yen, exceeding the full-year forecast of 52,000 million yen (achievement rate 106.2%). Operating profit increased to 12,425 million yen from 10,642 million yen a year earlier (116.8% of the FY2024 level), against a forecast of 12,000 million yen (achievement rate 103.5%), with operating profit margin improving to 22.5% from 21.7% a year earlier. The company says the margin improvement reflected enhanced productivity and revised sales prices that offset rising labor costs, raw material prices, and an increase in construction projects with high-cost ratios. Ordinary profit rose to 13,443 million yen from 10,830 million yen (124.1% of the FY2024 level) and net profit rose to 9,957 million yen from 8,007 million yen (124.3% of the FY2024 level), both well ahead of their respective forecasts. Basic earnings per share were 217.32 yen, up from 172.10 yen in FY2024.

For the fiscal year ending March 31, 2027, RIKEN KEIKI forecasts net sales of 60,000 million yen and operating profit of 12,700 million yen.
