[Business Results and Financial Conditions]

1. Analysis of business results

1. Summary

   In the three-month period ended March 31, 2026 ("2026Q1"), the global economy recovered moderately overall, although concerns remained regarding the impact of the situation in the Middle East. The semiconductor industry experienced steady growth, particularly in advanced applications such as AI. The Japanese economy also showed signs of recovery in personal consumption and corporate capital investment, and recovered moderately overall.

   Revenue for 2026Q1 increased from the same period last year ("2025Q1") in four segments -Semiconductor and Electronic Materials, which continued to perform strongly driven mainly by advanced semiconductor applications, as well as Mobility, Innovation Enabling Materials, and Chemicals- while Crasus Chemical segment recorded a decrease in revenue due to the impact of large-scale periodic shutdown maintenance conducted once every four years. In addition, affected by the impact of the business transfer of FIAMM Energy Technology S.p.A. included in Others (not included in reportable segments), overall revenue decreased to ¥307,892 million.

   Core operating profit decreased in Crasus Chemical segment due to lower revenue, while the four segments including Semiconductor and Electronic Materials recorded increases in profit and reductions in losses, resulting in overall profit of ¥33,616 million.

   Operating profit increased to ¥22,144 million, as the increase in core operating profit more than offset the rise in non-recurring items, including losses associated with the revision of the retirement benefit plan.

   As a result of the increase in operating profit and other factors, quarterly profit attributable to owners of the parent amounted to ¥15,283 million.

   (Unit: millions of yen)

   	2025 1Q Jan.-Mar.	2026 1Q Jan.-Mar.	Increase/ decrease	Increase/ decrease rate
   Revenue	321,122	307,892	(13,230)	(4.1)%
   Core operating profit	14,848	33,616	18,768	126.4%
   Operating profit	13,982	22,144	8,162	58.4%
   Profit attributable to owners of the parent	8,754	15,283	6,529	74.6%

2. A breakdown of revenue and core operating profit by segment (January 1 - March 31, 2026)

[Semiconductor and Electronic Materials]

In this segment, revenue from Front-end Semicondutor Materials increased due to a gradual recovery in memory market conditions. Revenue from Back-end Semiconductor Materials increased, mainly reflecting higher sales volumes for advanced semiconductors used in applications such as AI. In Device Solutions, although demand for data centers in HD media remained firm, revenue was in line with the same period of the previous fiscal year, affected by inventory adjustments in SiC epitaxial wafers.

As a result, this segment achieved increases in both revenue and core operating profit compared with 2025Q1.

(Unit: millions of yen)

[Mobility]

In this segment, revenue and core operating profit increased compared with 2025Q1, mainly due to the recovery of the automotive market in Thailand and increased demand from certain customers.

(Unit: millions of yen)

[Innovation Enabling Materials]

While there were differences in performance among products, the segment as a whole performed solidly, leading to higher revenue and core operating profit compared with 2025Q1.
