Kureha's core growth segment, encompassing PPS Resin, Polyvinylidene Fluoride Resin, PGA, and carbon products.
| Period | Current | Previous | Change |
|---|---|---|---|
| Revenue (FY2026, ending March 2026, full year) | ¥61,279 million | ¥57,372 million | ↑ |
| Operating income/loss (FY2026, ending March 2026, full year) | ¥2,134 million (operating income) | △¥1,991 million (operating loss) | ↑ |
| Impairment loss (FY2026, ending March 2026) | ¥33,996 million | - | ↓ |
Business Details
Main products include PPS Resin, Polyvinylidene Fluoride Resin, PGA (Polyglycolic Acid) Resin Processed Products, carbon fiber, and Spherical Activated Carbon. The segment offers Polyvinylidene Fluoride Resin for lithium-ion secondary battery binders, PGA Resin Processed Products for shale oil and gas drilling, and PPS Resin for automotive and electronic components, with manufacturing and sales bases both in Japan and overseas supplying globally. The EV and ESS markets are positioned as medium- to long-term growth drivers.
Recent Overview
Polyvinylidene Fluoride Resin declined due to the EV market slowdown, but PGA, PPS, and Spherical Activated Carbon drove increased revenue and a return to profitability.
Revenue for FY2026 (ending March 2026) increased 6.8% year on year to ¥61,279 million, and operating profit/loss turned positive, moving from a loss of ¥1,991 million in the prior period to income of ¥2,134 million. Sales of Polyvinylidene Fluoride Resin declined due to the continued slowdown in the EV market. On the other hand, increased sales of PGA Resin Processed Products and PPS Resin, together with lower raw material prices, contributed positively. The carbon products field also saw increased profit driven by higher sales of Spherical Activated Carbon. However, following a review of future earnings plans for the Polyvinylidene Fluoride Resin business, an impairment loss of ¥33,996 million on fixed assets was recorded (included in consolidated adjustments).

| Period | Current | Previous | Change |
|---|---|---|---|
| Revenue (external customers) | ¥29,487 million | ¥30,677 million | ↓ |
| Operating profit | ¥1,350 million | ¥592 million | ↑ |
| Operating profit margin | 4.6% | 1.9% | ↑ |
Business Details
In the agrochemicals and pharmaceuticals field, the company manufactures and sells Agricultural & Horticultural Fungicides and Kremezin (Agent for Chronic Renal Failure). In the industrial chemicals field, it manufactures and sells Inorganic Chemicals (Caustic Soda, Hydrochloric Acid, Sodium Hypochlorite) and Organic Chemicals (Monochlorobenzene, Paradichlorobenzene, etc.). Kureha Corporation itself serves as the core of manufacturing and sales, with sales also conducted through Kureha Trading Co., Ltd. This segment accounts for approximately 18% of the Group's consolidated revenue (FY2026, ending March 2026).
Recent Overview
Despite lower revenue, operating profit rose 128% year on year on higher agrochemical sales and lower raw material prices; an impairment loss was recorded on chronic renal failure treatment equipment
Revenue for FY2026 (ending March 2026) decreased 3.9% year on year to ¥29,487 million. In the agrochemicals and pharmaceuticals field, increased sales of Agricultural & Horticultural Fungicides offset the decline in Kremezin, resulting in increased revenue and profit for the field overall. In the industrial chemicals field, despite a decline in organic chemical sales, operating profit increased due to lower raw material prices. Meanwhile, an impairment loss of ¥2,504 million was recorded on manufacturing equipment for the chronic renal failure treatment agent, reflecting the emergence of new treatment drugs and drug price reductions (recorded as an adjustment outside the segment). Segment operating profit was ¥1,350 million, up 128.0% year on year.
