  1. 2026-05-12MaterialisedEarnings

    「Initial deliveries of heating equipment progressed steadily as distribution inventories returned to appropriate levels compared with the previous year, and exports of oil-fired heating equipment also performed steadily. However, heating equipment overall fell below the previous fiscal year, partly because temperatures during the demand season remained high nationwide.」

  2. FY2026-H1MaterialisedAnnual report

    「Sales of air-conditioning and household electrical appliances were ¥11,008 million, down 9.1% from the previous interim consolidated accounting period. Although window-mounted room air conditioners, which do not require installation work, performed well, sales of split-type units fell below the previous interim consolidated accounting period due in part to intensified competition among manufacturers. Dehumidifier sales also struggled, affected in part by the early end of the rainy season, and total sales of air-conditioning and household electrical appliances fell below the previous interim consolidated accounting period.」
