In the advanced plastics category, revenue and operating profit both declined due to lower sales of polyvinylidene fluoride (PVDF) for lithium-ion secondary battery binders, polyphenylene sulfide (PPS), and processed polyglycolic acid (PGA) products used in shale oil and gas extraction. Additionally, gains from the reversal of inventory valuation losses on PGA products were smaller than in the previous fiscal year.

In the carbon products category, although sales of bead-shaped activated carbon increased, revenue and operating profit both declined due to lower sales of heat insulating materials for high-temperature furnaces.

In the agrochemicals and pharmaceuticals category, revenue and operating profit both declined due to lower sales of agricultural and horticultural fungicides as well as Kremezin, a treatment for chronic renal failure.

In the industrial chemicals category, revenue and operating profit also declined due to reduced sales of both inorganic and organic chemicals.

In the consumer goods category, although sales of Seaguar fluorocarbon fishing lines increased, revenue and operating profit both declined due to lower sales of New Krewrap plastic wrap for household use.

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.

In Construction, revenue increased due to growth in both public and private-sector construction projects; however, operating profit declined as a result of changes in the sales mix.

In the environmental engineering category, revenue and operating profit both increased due to higher volumes of waste processing. In other businesses, revenue was on par with the previous year, but operating profit increased due to improved bed occupancy rates in the hospital operations.
