Union Materials

Union Materials was established in 2000 and listed on the KOSPI in 2009 as a specialized materials company producing ferrite magnets and fine ceramics. Its business consists of two main segments: the ferrite magnet business and the ceramics business.

Ferrite magnets are used in automotive electronics motors, home appliance motors, and compressors, serving as a substitute for rare-earth magnets, and the company has strengthened its position as a global first-tier supplier through in-house development and mass production, earning multiple awards from Bosch and Brose.

The ceramics business manufactures and sells industrial ceramic components including cutting tools, magnetron stems, and water valve discs. Its subsidiaries include Union Tooltech in China and Union Materials Vietnam, which serve as overseas production bases.

More recently, the company has been expanding into renewable energy and eco-friendly industrial fields through the development of solid oxide fuel cells, power semiconductor modules, and petrochemical-use ceramic parts. The controlling shareholder is Union Co.

(KOSPI: 000910), which operates cement and environmental machinery businesses and held roughly a 40% stake before the consolidation.

The ferrite magnet industry for automotive motors carries entry barriers such as lengthy durability testing and strict supply and quality requirements, which constrains the competitive landscape.

Consolidated revenue in 2025 was KRW 101.9 billion, slightly down from KRW 108.4 billion in 2024, while operating profit reached KRW 5.43 billion, reversing from an operating loss of KRW 16.5 billion the prior year.

Owners' net income also turned positive at KRW 2.46 billion, recovering from a large net loss of KRW 46.5 billion in 2024.

This turnaround masked significant quarter-to-quarter volatility: the company posted an operating loss of KRW 251 million and a net loss of KRW 795 million in the third quarter of 2025, before swinging to operating profit of KRW 3.60 billion and net income of KRW 5.04 billion in the fourth quarter, which drove the full-year result.

In the first and second quarters of 2026, operating profit was KRW 1.05 billion and KRW 714 million, with net income of KRW 463 million and KRW 322 million respectively—smaller than the fourth-quarter 2025 peak but still profitable.

Recently disclosed first-half 2026 results show ferrite revenue of KRW 31.3 billion, down 6.0% year over year from KRW 33.3 billion, and ceramics revenue of KRW 20.5 billion, down 1.6%, while first-half operating profit fell 15.0% year over year to KRW 1.8 billion.

In contrast, first-half net income turned positive at KRW 800 million versus a net loss in the prior-year period, with foreign-currency translation and exchange gains contributing significantly to the improvement.

Total equity fell from KRW 83.8 billion in 2022 to KRW 15.4 billion in 2024 after large losses in 2023 and 2024, before recovering modestly to KRW 19.6 billion in 2025. The debt ratio surged from 193.6% in 2023 to 796.4% in 2024 before easing to 594.9% in 2025, though liabilities relative to equity remain heavy.

Operating cash flow improved markedly to KRW 11.85 billion in 2025 from a net outflow of KRW 12.1 billion in 2022.

The ferrite magnet industry is an essential materials sector for automotive electronics motors and home appliance motors and compressors, characterized by large capital investment requirements and lengthy reliability qualification periods.

In particular, ferrite magnets used in automotive motors must pass extended durability testing and stringent quality requirements from automakers and parts suppliers, making new entry difficult.

As automotive electronics motors trend toward electrification, miniaturization, and higher efficiency, demand for high-performance ferrite magnets is expected to continue, while the home appliance motor market shows relatively greater demand volatility.

Because the company supplies ferrite magnets as a substitute for rare-earth magnets, it tends to draw market attention when rare-earth pricing or supply chain issues come into focus.

The ceramics business centers on industrial parts such as cutting tools and magnetron stems with relatively stable demand, more closely tied to broader industrial capital spending than to automotive market conditions.

At the same time, the company is expanding into renewable energy and eco-friendly materials such as solid oxide fuel cells and power semiconductor modules, an effort to reduce its historical dependence on the automotive and appliance end markets.

The company has pursued profitability improvement through cost reduction and productivity gains across both the ferrite magnet and ceramics businesses, which underpinned the return to annual profit in 2025 and the maintenance of profit in the first half of 2026.

Amid expectations for growing demand for high-performance ferrite magnets driven by miniaturization and efficiency trends in automotive and appliance motors, the pace at which newer development items such as solid oxide fuel cells, power semiconductor modules, and petrochemical-use ceramic parts reach commercialization is a variable that will shape the medium-term direction.

In the near term, a 5-for-1 share consolidation is underway, under which outstanding shares will be reduced from 42 million to 8.4 million and par value adjusted from KRW 500 to KRW 2,500, a move interpreted as a response to the risk of administrative-issue designation from the stock trading below KRW 1,000.

However, the consolidation itself does not bring new cash into the company or improve core profitability, and the KOSPI market capitalization listing maintenance threshold, rising from KRW 30 billion to KRW 50 billion starting next year, remains a separate challenge.

Whether controlling shareholder Union Co.'s recent additional share purchases are followed by further ownership actions and balance-sheet improvement plans is also worth monitoring.

Given the increased short-term borrowing burden, whether the company improves its funding structure or pursues additional financing also warrants attention.
