Enplus

ENPlus was founded in 1980 as a fire-fighting machinery maker and changed its name to the current one in 2020 while expanding into the secondary battery business.

The company built a leading position at home and abroad as a specialized fire-truck manufacturer with proprietary technologies such as a water-pressure control system for fire trucks.

More recently it has extended into battery materials and components based on thermal-electrode technology, operating through four unlisted subsidiaries.

In 2022 the company secured a patent, developed jointly with Sogang University's technology holding company, for a carbon-silicon composite electrode material combining silicon nanoparticles with a porous carbon structure, laying a technical foundation for next-generation silicon anode materials.

It has also announced development of two new battery thermal-management materials that can be applied to AI semiconductors, along with a 'battery foundry' concept modeled on the semiconductor foundry structure, under which it would contract-manufacture everything from electrodes to finished cells.

Subsidiary Yulho is tasked with securing upstream battery raw materials through a waste-battery recycling business and mine development in Tanzania, Africa. The fire-truck segment tends to be heavily influenced by government budget allocations, and revenue has fallen in periods of budget cuts.

As a result, the company currently runs a transitional business structure straddling its legacy fire-equipment operations and its newer secondary-battery ventures.

On an annual basis, revenue rose from KRW 26.895 billion in 2022 to KRW 44.888 billion in 2023 and KRW 58.314 billion in 2024, before falling back to roughly half that level at KRW 29.504 billion in 2025.

Operating losses were large for three straight years — KRW -13.175 billion in 2022, KRW -23.921 billion in 2023, and KRW -22.385 billion in 2024 — before narrowing markedly to KRW -2.826 billion in 2025, with the operating margin improving from a range of roughly -38% to -53% in 2022-2024 to -9.6% in 2025.

Net income attributable to owners was KRW -36.295 billion, -58.085 billion, and -77.457 billion in 2022, 2023, and 2024 respectively, before turning positive at KRW 0.811 billion in 2025. Quarterly trends, however, show substantial volatility.

In 2025Q2 revenue was KRW 0.550 billion with an operating loss of KRW 0.260 billion and a net loss of KRW 5.002 billion; revenue then jumped to KRW 5.993 billion in Q3, turning operating income positive at KRW 0.701 billion while the net loss narrowed to KRW 0.031 billion.

In Q4, revenue reached KRW 13.098 billion with operating income of KRW 0.868 billion — a second straight quarter of operating profit — yet the net loss widened again to KRW 9.176 billion, suggesting a large non-operating item unrelated to core operations.

In 2026, revenue fell back (KRW 6.303 billion in Q1, KRW 2.243 billion in Q2), pushing operating results back into loss at KRW -0.638 billion and KRW -1.155 billion respectively, with net losses of KRW 0.608 billion and KRW 1.221 billion.

As a result, the sum of net income attributable to owners over the latest four quarters (2025Q3-2026Q2) was KRW -11.037 billion, a very different picture from the positive full-year 2025 figure.

On the balance sheet, equity attributable to owners plunged from KRW 78.502 billion in 2023 to KRW 9.854 billion in 2024, pushing the debt ratio up to 1,243.9%, before recovering to KRW 14.152 billion in equity and a debt ratio of 200.5% in 2025, likely related to capital raises and balance-sheet restructuring carried out during that period.

The secondary battery materials industry has expanded alongside EV demand growth, but a recent demand slowdown has intensified price competition and oversupply concerns among anode and copper-foil material makers.

Graphite, a core anode material input, is a mineral with heavy reliance on China, with both natural and artificial graphite imports reportedly exceeding 90% dependence on China.

As a result, domestic and global battery and materials companies are competing to secure non-China supply chains, and silicon anode materials are seen as a next-generation material that multiple large companies are pursuing commercially due to expected energy-density improvements over graphite.

Silicon anode materials still face technical challenges such as volume-expansion control and cost, so the pace of commercialization varies by company.

Domestic materials major POSCO Future M invested KRW 460 billion to build a 13,000-ton artificial graphite anode plant, an example of far larger capital and production capacity than ENPlus currently commands.

Compared with such large incumbents, ENPlus can be classified as a small, later-stage entrant still closer to the development and patent-securing stage than to full commercial production.

Mineral resource development through subsidiaries (Tanzania nickel/graphite) and waste-battery recycling align with the trend toward raw-material supply-chain diversification, but early-stage exploration and drilling projects generally require substantial time and additional investment before reaching commercialization.

The company is running its legacy fire-truck business alongside newer secondary-battery ventures, and has recently unveiled several new business concepts in succession.

Notably, it has proposed a 'battery foundry' business modeled on the semiconductor foundry structure, under which it would contract-manufacture everything from electrodes to finished cells, and has said it secured a new plant site within a free-trade zone in Gimje, North Jeolla Province, in cooperation with local government.

Subsidiary Yulho has said it secured exploration rights for nickel and graphite mines in Tanzania and plans to move from exploration to drilling once exploration is complete, and it was also selected for a government-backed critical minerals supply chain expansion support project.

The company has also mentioned a policy of prioritizing domestic supply of low-grade nickel ore, positioning itself as a contributor to the domestic battery materials supply chain.

It continues to expand its materials portfolio, saying it developed two new battery thermal-management materials that can also be applied to AI semiconductors.

However, most of these new ventures remain at an early stage prior to construction, drilling, or mass production, and the timing and scale of any eventual revenue contribution have not yet been confirmed.

Given that multiple capital raises and a change of largest shareholder took place in 2025, a key point to watch going forward will be how much of that capital is actually deployed into these new ventures and whether it translates into results.
