Recent Overview
Sharp increases in both revenue and operating profit driven by full-scale operation of new domestic lines, continued North American demand, and the start of wick sheet mass production.
In FY2026 (ending March 2026), full-scale operation of new domestic production lines and continued automotive demand in the North American market, combined with increased sales at overseas subsidiaries, contributed to results. In addition, the start of full-scale mass production of the new Wick Sheets for Smartphone Vapor Chambers product also contributed, resulting in net sales to external customers of ¥25,721 million (up 12.4% year on year) and operating profit of ¥1,877 million (up 269.0% year on year), representing substantial increases in both revenue and profit. Capital expenditures expanded significantly to ¥5,735 million from ¥2,946 million in the prior period, reflecting continued active investment aimed at increasing production capacity going forward.
