1. Overview of operating results, etc

   1. Overview of operating results during the period

      During the third quarter of the fiscal year ending March 31, 2026 (April 1, 2025 through December 31, 2025), the economic environment saw progress in forming agreements on trade policies among major countries, reducing the uncertainty that had previously prevailed. In the United States, although concerns over persistently high inflation remained, the Federal Reserve Board (FRB) implemented three consecutive interest rate cuts since September in response to a slowdown in employment conditions, which eased financial conditions and supported personal consumption and capital investment. In Europe, defense-related spending and investments in the IT sector helped mitigate economic deterioration, while recovery in manufacturing industries such as automobiles continues to be sluggish. In China, the government's continued implementation of a trade-in program to promote the replacement of consumer goods supported personal consumption, and demand for semiconductors and IT-related products remained strong. Additionally, exports routed through Southeast Asian countries to circumvent U.S. tariffs continue to show an upward trend. In Japan, business sentiment improved, and capital investment plans were revised upward, indicating resilient corporate confidence. However, cautious stance is evident in forward-looking assessments, with concerns over geopolitical risks and rising costs persisting.

      Under these circumstances, in the key markets of Nitto Group (the "Group"), production units of IT devices and high-end smartphones exceeded expectations, leading to increased demand for our products. In oligonucleotide contract manufacturing business, a project related to major diseases progressed from the clinical stage to the commercialization stage, contributing to improved profitability. Separately, the yen's exchange rate against the U.S. dollar for the third quarter ended December 31, 2025, was 148.6 yen to the dollar, a 2.6% appreciation of the yen compared with the same period of the previous year, and the effect of the stronger yen decreased operating profit by 8.8 billion yen.

      As a result of the above, revenue increased by 1.0% from the same period of the previous year (changes hereafter are given in comparison with the same period of the previous year) to 786,195 million yen. Operating profit decreased by 3.3% to 147,860 million yen, profit before income taxes decreased by 2.7% to 148,682 million yen, net profit decreased by 2.8% to 105,735 million yen, and net profit attributable to owners of the parent company decreased by 2.7% to 105,703 million yen.

      Summary of results by segment

      ① Industrial Tape

      In Functional Base Products, revenue increased from the same period of the previous year. Demand for assembly materials used in high-end smartphones increased due to the expansion of models adopting battery bonding electrical release tape. In addition, demand for process materials used in the production of semiconductor memories and ceramic capacitors increased. Revenue for automotive materials decreased due to the decline in the number of automotive unit production by Japanese manufacturers in China.

      As a result of the above, revenue increased by 3.0% to 275,074 million yen and operating profit increased by 3.0% to 38,847 million yen.

      ② Optronics

      In Information Fine Materials, revenue did not reach the level of the same period of the previous year. Demand for optical films increased as production units of high-end laptop PCs and tablets remained strong. On the other hand, revenue decreased due to the strategic withdrawal from optical films for LCD smartphones and price reductions resulting from material rationalization of process protection films.

      In Circuit Materials, revenue did not reach the level of the same period of the previous year. Demand for high-precision circuits increased due to the strong production of high-end smartphones. On the other hand, demand for Circuit Integrated Suspension (CIS) used in Hard Disk Drives (HDDs) remained at the same level as in the same period of the previous year, during which the HDD market experienced a rapid recovery in demand.

      As a result of the above, revenue decreased by 2.4% to 412,000 million yen and operating profit decreased by 12.6% to 120,506 million yen.

      ③ Human Life

      In Life Science, revenue increased from the same period of the previous year. Demand for oligonucleotide contract manufacturing and nucleic acid synthesis materials (NittoPhaseTM) used within the manufacturing process increased. Additionally, production for the large-scale project expected to be commercialized in the future began in the second quarter of the current fiscal year. In nucleic acid drug discovery, Phase 1 clinical trial of intractable cancer drug was completed in the first quarter of the previous fiscal year and the Group continues to work toward out-licensing its pipeline.

      In Membrane (high-polymer separation membrane), revenue did not reach the level of the same period of the previous year. While demand for Zero Liquid Discharge (ZLD) contributing to the complete reduction of industrial wastewater and effluent remained strong in China due to the tightening of environmental regulations relating to wastewater, demand for high-polymer separation membrane for various industrial applications decreased.

      In Personal Care Materials, revenue increased from the same period of the previous year. The Group promoted our new products in hygiene materials for diapers and environmentally friendly products using biodegradable technologies. Separately, the Group recorded an impairment loss on fixed assets of 1,436 million yen in the third quarter of the current fiscal year.

      As a result of the above, revenue increased by 8.0% to 106,922 million yen and operating loss amounted to 2,535 million yen. (operating loss of 5,723 million yen was reported in the same period of the previous year)

      ④ Others

      Please note that this segment includes new products that have not generated sufficient revenue yet. The Group is concentrating our management resources on themes that are candidates for PlanetFlags/HumanFlags in areas of next generation semiconductors, environmental solutions, and digital health, with the aim of commercializing them as early as possible.

      As a result of the above, revenue increased by 184.5% to 10 million yen and operating loss amounted to 5,333 million yen. (operating loss of 10,484 million yen was reported in the same period of the previous year)
