Cenotec

Founded in 1999, Cenotec is South Korea's sole domestic producer to have successfully mass-produced ceramic beads. Its business consists of four segments: grinding and dispersion ceramic beads, ceramic powder, ceramic carriers, and secondary battery additives.

Its main customers span MLCC and battery material manufacturing, mining, paper/ink/paint, marine welding, hydrogen industry, and petrochemicals. Ceramic beads for electronics and mining/paper applications are the core products, alongside flux, ceramic powder, and catalyst carriers.

Since 2024 the company has built a cathode material additive business aimed at reducing reliance on China, achieving localization and beginning full-scale supply from Q1 2025. This new business has passed quality audits at three domestic cathode material makers, with roughly six approved products.

In November 2025 it signed an MOU with global battery materials company Umicore for cobalt business cooperation, and in February 2026 completed its first mass shipment of cobalt hydroxide additive.

The controlling shareholder is E&F Marble Holdings, a special-purpose vehicle of environmental-focused private equity firm E&F PE, which took control in 2017 and has since shifted the business mix away from mining dependence toward electronics and battery materials.

A high proportion of raw materials such as alumina and zirconia are sourced from China, making supply diversification an ongoing management priority.

Consolidated 2025 revenue rose to KRW 35.64 billion from KRW 31.55 billion in 2024, while operating profit surged to KRW 3.17 billion from KRW 0.95 billion, lifting the operating margin from 3.0% to 8.9%.

Net income attributable to owners swung from a loss of KRW 2.53 billion in 2024 to a profit of KRW 1.35 billion in 2025.

In 2023 the company posted revenue of KRW 31.11 billion with an operating loss of KRW 1.06 billion, and in 2022 it recorded an operating profit of KRW 1.13 billion but still a small net loss of about KRW 72 million.

On a quarterly basis, 2025 Q2 revenue was KRW 9.09 billion with operating profit of KRW 0.96 billion despite a net loss of KRW 0.31 billion, while Q3 revenue reached KRW 10.01 billion with operating profit of KRW 0.73 billion and net profit of KRW 0.26 billion.

Q4 2025 revenue was KRW 9.07 billion with operating profit jumping to KRW 1.32 billion and net profit expanding to KRW 2.02 billion.

Q1 2026 revenue was KRW 10.46 billion with operating profit softening to KRW 0.55 billion, before Q2 2026 revenue rebounded to KRW 12.83 billion with operating profit of KRW 1.57 billion and net profit of KRW 1.16 billion.

Over the trailing four quarters from Q3 2025 through Q2 2026, net income attributable to owners totaled roughly KRW 3.76 billion, a full recovery from the 2024 annual net loss.

The debt-to-equity ratio climbed to 161.1% in 2023 before easing to 152.7% in 2024 and 118.2% in 2025, and operating cash flow jumped to about KRW 8.2 billion in 2025 from roughly KRW 1.4 billion in both 2024 and 2023, indicating the profitability recovery is translating into stronger cash generation.

Ceramic beads serve as consumable materials across mining ore grinding, nano-processing of MLCC and battery materials, semiconductors, and precision polishing applications. Demand for mining-grade beads is reportedly growing, centered on large Australian mines and new South American projects.

Beads for electronics are growing on the back of expanded supply to MLCC and battery material producers. In the battery additive market, the company's utilization rate rose from 22% last year to 69% in the first half of this year, suggesting the new business is gaining traction.

On the raw material side, dependence on Chinese-sourced alumina and zirconia remains high, prompting the company to diversify sourcing beyond South Africa and Australia into India and other South Asian regions while pursuing rare-earth recycling technology.

Competitively, the company holds a unique position as the only domestic mass producer of ceramic beads, though in battery additives it must compete against larger global materials companies.

Supply chain realignment driven by U.S. de-risking policies away from China is cited as a potential opportunity for a company with a domestic production base.

To meet growing demand for battery additives, the company said it plans to roughly double its production lines in the second half of this year versus the first half, and more than double them again next year.

In May 2026 it signed a KRW 4.6 billion battery cathode additive supply contract with domestic and overseas cathode material makers, running through December 31, 2026.

In March 2026 it signed a business cooperation agreement with Chinese bead mill maker INFOR and is pursuing a grinding technology center at its Haman headquarters, expanding technical collaboration.

On the governance side, controlling shareholder E&F PE reportedly attempted a sale in 2024 that fell through over price disagreements, and is said to be pursuing another exit built on the momentum of the battery materials business.

The company continues a debt-reduction policy to strengthen its balance sheet, and has stated it plans to redeem convertible bond obligations using its own cash rather than additional borrowing.

With new customer expansion in battery additives and geographic diversification of the legacy ceramic bead business proceeding in parallel, how stably these two growth engines mesh will be a key watch point for future results.
