(Operating Results for the current fiscal year)

For the current fiscal year (from April 1, 2025 to March 31, 2026), the global economic outlook remained uncertain amid the continued impact of various policies by the U.S. administration, including reciprocal tariffs, increasing geopolitical risks due to the prolonged Russia-Ukraine situation and rising tensions in the Middle East, as well as ongoing volatility in foreign exchange markets.

In the major industries related to the Group's products, the consumer IT market remained firm for the full fiscal year, although concerns emerged from the second half regarding the impact of soaring memory prices. In the automotive market, while the competitive environment in the Chinese market intensified, production volumes remained solid due to the progress of electrification. In the market for optical transceivers for data centers, demand remained strong against the backdrop of the widespread adoption of generative AI. Under these business conditions, the Group worked to expand a business portfolio less susceptible to changes in the business environment in accordance with its Mid-Term Management Plan. In growth domains, shipment volumes of products for optical transceivers for data centers and telecommunication equipment increased in the photonics business. In the automotive business, although customers' sales volumes declined due to intensifying competition in the Chinese automotive market, net sales increased slightly owing to an increase in the number of models adopting Anti-reflection films (ARF) and the expansion of display sizes. In existing domains, although sales of Phosphor films were terminated by the end of the first half of the previous fiscal year, sales of high-value-added products expanded, particularly camera module-related products for high-end smartphones, such as Pre-cut Anisotropic Conductive Films (ACF).

As a result, for the current fiscal year, net sales were ¥113,832 million (up 3.1% year-on-year), business profit was ¥39,352 million (up 3.4% year-on-year), operating profit was ¥38,097 million (down 4.1% year-on-year), and profit attributable to owners of parent was

¥28,009 million (up 1.0% year-on-year).

The performance of each segment is as follows.

(Millions of yen)

(Note) Net sales include inter-segment transactions.

Regarding net sales, in Anti-reflection films (ARF), products for laptop PC displays performed strongly through the first half, supported by replacement demand for end products that had continued since the second half of the previous fiscal year. However, demand stabilized in the second half, and sales decreased slightly due to a decline in sales volumes of certain adopted models in the fourth quarter. On the other hand, sales of products for automotives increased slightly owing to an increase in the number of adopted models and the expansion of display sizes, resulting in overall net sales remaining flat.

In Smart precision Adhesives, products for high-end smartphones remained firm due to increased sales volumes of adopted models. On the other hand, for the segment, net sales amounted to ¥47,971 million (down 5.3% year-on-year), due to the impact of the termination of sales of Phosphor films at the end of the first half of the previous fiscal year.

Regarding profit, despite the positive impact from increased sales of Smart precision Adhesives, business profit amounted to ¥14,308 million (down 1.7% year-on-year), mainly due to the impact of decreased sales of high value-added products such as Anti-reflection films (ARF) for laptop PC displays.
