‌Summary of Consolidated Financial Results for 1Q FY3/26

Accounting Period of 1Q FY3/26

JCU (non-consolidated): April 1 to June 30, 2025

Overseas subsidiaries: January 1 to March 31, 2025

For electronic

components

Chemicals Business

China: Demand for PWBs and semiconductor package substrates for various high-performance electronic devices such as smartphones and PCs remained strong, resulting in a substantial year-over-year increase in sales of chemicals.
Taiwan: Demand for semiconductor package substrates for high-performance electronic devices such as smartphones and
servers moderately expanded. As a result, sales of chemicals increased year over year.
South Korea: Due to the bottoming out of the semiconductor market and the progress in inventory adjustment by customers, demand for semiconductor package substrates continued a moderate recovery. As a result, sales of chemicals increased year over year.
For
decoration

Japan: Demand for chemicals declined due to changes in design trends. As a result, sales of chemicals decreased year over year.
Machine Business
China: Despite increases in automobile production due to the effect of various policy measures boosting demand, demand for automobile parts which is subject to our business decreased. As a result, sales of chemicals stayed flat year over year.
Sales increased thanks to the ordered projects progressing on schedule. However, orders received and order backlog decreased due to a decline in new orders for large projects.
