1. Overview of Operating Results, etc.

(1) Business results

During the third quarter of the fiscal year ending March 31, 2026 (April 1 to December 31, 2025), concerns over geopolitical risks persisted due to developments in the Middle East and Ukraine, as well as heightened attention to monetary policies in various countries and 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.

In our business, working within this business environment, while the next-generation high-speed communications-related business continued to remain at a high level, a recovery was observed in the automobile- and semiconductor-related businesses, which had experienced weaker market conditions during the first half of the fiscal year.

As a result, consolidated net sales for the third quarter of the fiscal year ending March 31, 2026, decreased by 1.7% year on year to 52,225 million yen, operating profit decreased by 13.2% to 17,124 million yen, ordinary profit decreased by 10.0% to 18,029 million yen, and quarterly net profit attributable to owners of the parent decreased by 11.7% year on year to 12,332 million yen.

From the fourth quarter onward, growth in the telecommunication-related business is expected to accelerate due to a significant increase in production for next-generation high-speed communication. In the next fiscal year, we expect a full-scale recovery in the automobile- and semiconductor-related businesses. Toward achieving our medium-term plan targeting net sales of 100 billion yen in the fiscal year ending March 31, 2029, we will continue to steadily focus on strengthening our business foundation.

Sales and profits by segment are as follows.

(Ceramic Components Business)

In this segment, while the next-generation high-speed communications-related business continued to remain at a high level, a recovery was observed in the automobile- and semiconductor-related businesses, which had experienced weaker market conditions during the first half of the fiscal year.

As a result, net sales for the third quarter of the fiscal year ending March 31, 2026, decreased by 3.4% year on year to 45,023 million yen, and segment profit decreased by 15.5% year on year to 16,906 million yen.

(Lighting Equipment Business)

This segment performed solidly, supported by strong demand for lighting products for the high-end new condominium market, as well as steady progress in public LED lighting installation projects.

As a result, net sales for the third quarter of the fiscal year ending March 31, 2026, increased by 9.8% year on year to 7,201 million yen, while segment profit increased by 61.9% year on year to 1,418 million yen.

(2) Financial conditions

(Assets)

Current assets at the end of the third quarter of the fiscal year ending March 31, 2026, totaled 100,691 million yen, an increase of 401 million yen from the end of the previous fiscal year, primarily due to an increase in accounts receivable. Non-current assets amounted to 51,979 million yen, an increase of 9,983 million yen from the end of the previous fiscal year, mainly attributable to an increase in construction in progress.

As a result, total assets amounted to 152,670 million yen, an increase of 10,384 million yen from the end of the previous fiscal year.

(Liabilities)

Current liabilities at the end of the third quarter of the fiscal year ending March 31, 2026, amounted to 11,306 million yen, a decrease of 2,626 million yen from the end of the previous fiscal year, primarily due to a decrease in income taxes payable. Non-current liabilities amounted to 528 million yen, an increase of 30 million yen from the end of the previous fiscal year, mainly due to an increase in deferred tax liabilities.

As a result, total liabilities amounted to 11,835 million yen, a decrease of 2,596 million yen from the end of the previous fiscal year.

(Net Assets)

Net assets at the end of the third quarter of the fiscal year ending March 31, 2026, amounted to 140,835 million yen, an increase of 12,981 million yen from the end of the previous fiscal year, primarily due to the recording of 12,332 million yen in quarterly net profit attributable to owners of the parent.

As a result, the equity ratio was 92.2% (89.9% at the end of the previous fiscal year).

(3) Future outlook

There are no changes to the consolidated earnings forecast for the fiscal year ending March 31, 2026, which was announced on November 5, 2025.

Current outlook by segment is as follows.

In the telecommunication-related business, growth is expected to accelerate, driven by a significant increase in production from the fourth quarter onward following the full-scale launch of a successor model for next-generation high-speed communication. As end-user demand has further strengthened, we expect continued growth in the next fiscal year.

In the automobile-related business, inventory adjustments related to new energy vehicles have been completed, and the business has entered a recovery phase. From the next fiscal year, the business is expected to return to a growth phase. For medium- to long-term growth, we will continue to strengthen profitability through automation and yield improvement.

In the semiconductor-related business, demand related to generative AI remains strong, and differentiated high-purity SiC products have also begun to expand from the second half of the fiscal year. While a full-scale recovery in demand for general-purpose memory has been delayed, a steady recovery is underway. Toward a full market recovery in the next fiscal year, we will focus on strengthening production capacity at our new plant.

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.
