Business
KH Neochem Co., Ltd. is a petrochemical manufacturer that operates in three business areas—Functional Materials, Electronic Materials, and Basic Chemicals—centered on its core "oxo technology," which produces aldehydes from olefins and oxo gas as raw materials. The company traces its history to its founding in 1966 as a chemical manufacturing subsidiary of Kyowa Hakko Kogyo, and was listed on the First Section of the Tokyo Stock Exchange (now the Prime Market) in 2016. It operates two main production sites—the Yokkaichi Plant and the Chiba Plant—and has sales subsidiaries in the United States and China. Its principal products include refrigerator oil raw materials (isononanoic acid, octylic acid), cosmetics raw materials (1,3-butylene glycol), high-purity solvents for semiconductors and displays (PM-P, PMA-P), and plasticizer raw materials (octanol, isononyl alcohol), among others. Its main customers are chemical, electronics, automotive, and cosmetics manufacturers both in Japan and overseas, with Idemitsu Kosan (17.5% of net sales) and Miyako Chemical (9.9% of net sales) as key business partners.
Business Model
A manufacturing-and-sales integrated model that leverages proprietary Oxo reaction technology to produce a wide range of chemicals, from general-purpose products to high-value-added specialty products, selling directly to industrial customers both in Japan and overseas. The high-value-added Functional Materials and Electronic Materials segments accounted for approximately 93% of operating profit (FY2025), while Basic Chemicals functions as a stable supply base. The company maintains product competitiveness through capacity expansion and R&D investment, while also expanding its product lineup through a joint venture with Mitsubishi Chemical (J-Plus Co., Ltd.) and a subsidiary (Kurokin Kasei).
Company Strengths
Isononanoic acid and octylic acid are supplied to the global market as refrigerator oil raw materials for environmentally friendly air conditioners. Capacity expansion was completed in 2024, increasing production capacity. The Functional Materials segment generated net sales of ¥56,686 million (49.3% of the total) and operating income of ¥10,931 million (74.6% of the total), forming the core of earnings.
In 2022, a new quality control building equipped with an industry-leading cleanroom was constructed at the Yokkaichi Plant. The introduction of SPC (Statistical Process Control) enables the stable supply of ultra-low-metal, ultra-high-purity products. Against the backdrop of expanding demand for generative AI, operating income in the Electronic Materials segment grew to ¥2,681 million (up 11.4% year on year), with growth accelerating.
The equity ratio at the end of FY2025 remained at a stable level of 53.6%. Cash flow from operating activities was secured at ¥13,783 million (approximately double the previous fiscal year). Interest-bearing debt (excluding leases) stood at ¥16,949 million, and net interest-bearing debt was ¥10,230 million, both at low levels, underpinning a financial base that supports both growth investment and shareholder returns.
ENVALITH's Perspective
Performance Trend
Revenue peaked at ¥117,110 million in FY2021 and has since moved sideways to lower, coming in at ¥115,098 million in FY2025. Cumulative Q1 FY2026 revenue was ¥25,581 million (down 11.2% year on year), representing a decline. Operating profit has also been on a downward trend since ¥19,685 million in FY2021, falling to ¥11,248 million in FY2025, with cumulative Q1 FY2026 operating profit of ¥2,094 million (down 22.6% year on year). External factors—including inventory adjustments in the air conditioner market stemming from U.S. refrigerant regulations, the real estate downturn in China, sluggish housing starts in Japan, and an inflow of imported products—have weighed on earnings. On the other hand, expansion in Electronic Materials (High-Purity Solvents, Cutting-Edge Semiconductor Materials) driven by generative AI demand has provided partial support. The full-year forecast maintains operating profit of ¥13,500 million (up 20.0% year on year), but the Q1 progress rate stands at only 15.5%.
Growth Strategy
Aiming to upgrade the earnings structure through expanded sales of refrigerator oil raw materials and electronic materials, and the creation of new businesses
Capturing quality-enhancement needs driven by generative AI and advancing semiconductor sophistication and miniaturization, while strengthening quality control and stable supply systems. In 1Q FY2026 (ending March 2026), net sales increased 22.5% and operating profit increased 33.0%, progressing at a pace exceeding the plan.
A strategy to capture the medium-term growth of the air conditioner market, primarily in emerging countries, leveraging the production capacity expansion completed in 2024. In 1Q FY2026 (ending March 2026), sales volume declined due to inventory adjustments stemming from U.S. refrigerant regulations and the impact of China's real estate downturn, with the company currently awaiting the resolution of the inventory adjustment.
Working to expand sales domestically and overseas, centered on high-quality grade products. In 1Q FY2026 (ending March 2026), sales expansion activities continued, but the Functional Materials segment overall saw a decline in revenue due to the significant impact of lower sales of refrigerator oil raw materials.
Promoting new business development in polyhydroxybutyrate (PHB) and sugar chains, among others, as well as carbon neutrality initiatives utilizing the CO₂ capture equipment at the Chiba Plant. There has been no specific progress disclosure in the financial results report, and this remains an ongoing medium- to long-term initiative.
