1. Qualitative Information related to Consolidated Financial Results (1) Explanation of Consolidated Financial Results In the automotive market, one of the main business fields of the Group, the production volume in Japan was 2,029 thousand units, up 3.7% from the same period last year, while in North America (U.S. and Canada), 3,021 thousand units were manufactured, down 0.2% from the same period last year. In China, 6,912 thousand units were manufactured, down 6.9% from the same period last year, and in Thailand, 384 thousand units were manufactured, up 4.3% from the same period last year. (All calculations are based on the figures of each region at the end of the quarter.) In the data communications market, the Group’s other main business field, the total demand for suspensions, the Group’s main product, increased due to an increase in demand for high-capacity HDDs (Hard Disk Drives) for data centers, in addition to a year-on-year increase in global HDD shipments. As a result of the business environment mentioned above, the Group recorded net sales of 216,159 million yen (up 8.1% year-on-year), operating profit of 14,356 million yen (up 30.0% year-on-year), ordinary profit of 20,644 million yen (up 71.7% year-on-year), and profit attributable to owners of parent of 15,726 million yen (up 75.2% year-on-year). Results by segment are as follows: [Automotive Suspension Springs Business] In the automotive suspension springs business, although sales translated into yen at overseas subsidiaries increased, due to the impact of U.S. tariffs and the recognition of one-time costs, etc., net sales increased by 3.8% year-on-year to 43,421 million yen, and operating loss was 510 million yen (compared to an operating profit of 272 million yen in the same period last year). [Automotive Seating Business] In the automotive seating business, due to increased sales translated into yen at overseas subsidiaries and changes in vehicle model and product mix, etc., net sales increased by 0.6% year-on-year to 74,075 million yen, and operating profit increased by 0.4% year-on-year to 1,793 million yen. [Precision Springs and Components Business] In the precision springs and components business, due to an increase in production volumes of automotive components and HDD mechanical components, etc., net sales increased by 8.8% year-on-year to 28,062 million yen, and operating profit increased by 26.2% year-on-year to 1,304 million yen. [DDS Business] In the DDS (Disk Drive Suspension) business, sales volumes of HDD suspensions increased year-on-year due to continued growth in demand for high-capacity HDDs for data centers . As a result, net sales increased by 24.0% year-on-year to 37,637 million yen, and operating profit increased by 43.1% year-on- year to 9,057 million yen.

[Industrial Machinery and Equipment, and Other Operations Business] In the industrial machinery and equipment, and other operations business, due to an increase in production volumes of semiconductor process components and metal substrates , net sales increased by 16.2% year-on-year to 32,962 million yen, and operating profit increased by 66.7% year-on-year to 2,711 million yen. (2) Explanation of Consolidated Financial Position Total assets increased by 16,832 million yen from the end of the previous consolidated fiscal year to 755,282 million yen, mainly due to an increase in cash and deposits, as well as an increase in investment securities due to the market valuation of listed shares held. Liabilities increased by 1,400 million yen from the end of the previous consolidated fiscal year to 286,815 million yen, mainly due to increases in the provision for bonuses and electronically recorded obligations - facilities, despite decreases in long-term borrowings and income taxes payable. Net assets increased by 15,431 million yen from the end of the previous consolidated fiscal year to 468,466 million yen, mainly due to an increase in retained earnings resulting from profit attributable to owners of parent and an increase in valuation difference on available-for-sale securities. (3) Explanation Regarding Future Projection Including Consolidated Financial Forecasts The consolidated earnings forecasts for the full year ending March 31, 2027 remain unchanged from those announced on May 11, 2026. However, the earnings forecasts for each business segment have been revised as follows.
