In the advanced materials category, although sales of polyvinylidene fluoride (PVDF) resin for lithium-ion secondary battery binders declined, sales of processed polyglycolic acid (PGA) resin products for shale oil and gas drilling applications and polyphenylene sulfide (PPS) resin increased. Combined with falling raw material prices, these factors resulted in increases in both revenue and operating profit in this category.

In the carbon products category, sales of spherical activated carbon increased, resulting in increases in both revenue and operating profit.

In the agrochemicals and pharmaceuticals category, although sales of Kremezin, a therapeutic agent for chronic kidney disease, declined, sales of agricultural and horticultural fungicides increased, resulting in increases in both revenue and operating profit in this category.

In the industrial chemicals category, revenue declined due to reduced sales of organic chemicals; however, operating profit increased as a result of falling raw material prices.

In the consumer goods category, higher sales of New Krewrap plastic wrap for household use and Seaguar fluorocarbon fishing lines led to increases in both revenue and operating profit in this segment.

In the commercial food packaging materials category, revenue and operating profit both declined following the discontinuation of heat-shrink multilayer film sales during the first half of the fiscal year.

Both revenue and operating profit increased as large-scale projects progressed steadily in both public and private sector constructions.

In the environmental engineering category, revenue and operating profit both declined due to lower volumes of waste processing.
In other businesses, both revenue and operating profit declined.
