1. Overview of Operating Results, etc. (1) Business Results During the first half of the fiscal year ending March 31, 2026 (April 1 to September 30, 2025), concerns over geopolitical risks persisted due to ongoing developments in the Middle East and Ukraine, as well as the global focus on tariff policies involving the United States and other countries. In the high-tech market, rapid technological advancements and active investments were observed across a wide range of fields related to generative AI. Working within this business environment, while the next-generation high-speed communications-related business remained at a high level, weaker market conditions were observed in the automobile- and semiconductor-related businesses. As a result, consolidated net sales for the first half of the fiscal year ending March 31, 2026, decreased by 4.9% year on year to 33,115 million yen, operating profit decreased by 15.2% to 10,843 million yen, and ordinary profit decreased by 7.3% to 11,123 million yen. Net profit attributable to owners of the parent decreased by 12.2% year on year to 7,413 million yen. For the full year, we expect a recovery trend in the automobile and semiconductor-related businesses starting from the third quarter. In addition, supported by the growth of the generative AI market, the telecommunication-related business is projected to see accelerated growth from the fourth quarter onward, driven by the full-scale launch of a successor model for next- generation high-speed communication. Based on the above, we expect to achieve record-high results for the full year, with net sales of 75,100 million yen and operating profit of 27,000 million yen. The annual dividend for the fiscal year ending March 31, 2026, is planned to be 102 yen per share, an increase of 8 yen from the previous fiscal year. Sales and profits by segment are as follows. (Ceramic Components Business) In this segment, while the telecommunication-related business remained firm, the semiconductor- and automobile-related businesses experienced weaker market conditions. As a result, net sales for the first half of the fiscal year ending March 31, 2026, decreased by 5.8% year on year to 28,950 million yen, and segment profit decreased by 16.0% year on year to 10,945 million yen. For the full year, we expect a recovery trend in the automobile and semiconductor-related businesses, while growth in the telecommunication-related business is projected to accelerate with the full-scale launch of a successor model for next- generation high-speed communication, resulting in increases in both sales and profits. (Lighting Equipment Business) This segment saw steady performance, mainly in high-end lighting products, supported by increasing demand for LEDs due to Japan’s upcoming policy to phase out fluorescent lamp production by 2027 and the expansion of the high-end new condominium market in metropolitan area. As a result, net sales for the first half of the fiscal year ending March 31, 2026, increased by 1.5% year on year to 4,164 million yen, while segment profit rose by 42.4% year on year to 702 million yen. For the full year, we expect business performance to remain solid, mainly driven by high-end lighting for the high-end new condominium market in metropolitan area. (2) Financial Conditions (Assets) Current assets at the end of the first half of the fiscal year ending March 31, 2026, totaled 99,535 million yen, a decrease of 754 million yen from the end of the previous fiscal year, primarily due to a reduction in accounts receivable. Non-current assets increased by 6,384 million yen to 48,380 million yen. As a result, total assets amounted to 147,915 million yen, an increase of 5,630 million yen from the end of the previous fiscal year. (Liabilities) Current liabilities at the end of the first half of the fiscal year ending March 31, 2026, decreased by 1,893 million yen to 12,039 million yen. Non-current liabilities increased by 17 million yen to 515 million yen. As a result, total liabilities decreased by 1,876 million yen to 12,555 million yen. (Net Assets) Net assets at the end of the first half of the fiscal year ending March 31, 2026, increased by 7,506 million yen to 135,360 million yen, primarily due to the recording of 7,413 million yen in interim net profit attributable to owners of the parent. As a result, the equity ratio was 91.5% (89.9% at the end of the previous fiscal year).

(3) Future Outlook Based on the results for the first half, we have revised our consolidated full-year forecast for the fiscal year ending March 31, 2026, which was initially announced on April 25, 2025. For the second half, growth is expected to accelerate due to increased production for next-generation high-speed communication. For the full fiscal year, we continue to expect increases in both revenue and profit. Current outlook by segment is as follows. In the telecommunication-related business, progress is expected to exceed the initial forecast. With the full-scale launch of a successor model for next-generation high-speed communication, end-user demand has further strengthened, and we expect continued growth in the next fiscal year. In the automobile-related business, growth for new energy vehicles has slowed due to market conditions. However, we anticipate a recovery from inventory adjustments. For medium- to long-term growth, we will continue to strengthen profitability through automation and yield improvement. In the semiconductor-related business, although the market recovery in demand for general-purpose memory has been slow, a steady recovery is underway. Demand related to generative AI remains strong, and with the expansion of differentiated high- purity SiC products for SPE, sales are expected to grow from the second half of the fiscal year. In the industrial equipment-related business, demand for power modules has slowed due to market conditions, but demand for new medical-related products is increasing. In the lighting equipment-related business, high-end lighting products continue to perform steadily, supported by increasing LED demand due to Japan’s upcoming policy to phase out fluorescent lamp production by 2027 and the expansion of the high- end new condominium market in metropolitan areas. On the earnings front, we will continue to enhance profitability through further factory automation and improved yields on new products. Regarding profit figures below ordinary profit, it is difficult to provide forecasts at this time due to the potential volatility caused mainly by exchange rate fluctuations. As part of our medium-term plan, we aim to achieve net sales of 100 billion yen in the fiscal year ending March 31, 2029, and we are pleased to report that steady progress is being made toward this goal, even taking into account ongoing changes in the EV market environment. The assumed exchange rate for the full-year consolidated earnings forecast remains unchanged from the initial forecast at 144 yen per U.S. dollar.
