EMnI

EM&I was founded in 1999 and listed on KOSDAQ in 2008, with its core business being the development, manufacturing, and sale of organic emitting materials for OLED displays.

More recently the company has been expanding into secondary battery and renewable energy-related new businesses, with particular focus on oxide-based solid electrolyte materials for solid-state batteries.

This effort is led through subsidiary EmergeLabs (46% owned), a materials R&D specialist combining sol-gel based oxide electrolyte synthesis technology with AI-simulation-based materials design to improve ionic conductivity and optimize mass-production processes.

EmergeLabs signed a joint next-generation battery electrolyte development agreement with Nasdaq-listed AI materials simulation firm Schrodinger and was also selected for the Ministry of SMEs and Startups' Global TIPS program.

Another new-business pillar is heavy water, a strategic material used in semiconductor and display processes, battery materials, and cosmetics/bio research, for which the company has secured import-purpose confirmations from the Ministry of Trade, Industry and Energy and the Nuclear Safety and Security Commission.

Overseas, the company signed a lithium-ion cell supply agreement with Indian battery firm ADVANTEX Battery LLP, leveraging its network in the Indian market.

Following a recent change of control, a new majority shareholder—an edtech-focused investment fund led by a former Megastudy-affiliated executive—has taken over, and is reportedly reviewing a next-generation edtech platform business that combines a major domestic education content partner with the company's existing AI and robotics technology infrastructure.

As such, the company is in a transition period, simultaneously pursuing business realignment across its legacy OLED materials business, heavy water, solid-state battery materials, and now potentially edtech.

Annual results have shown pronounced swings.

In 2022 revenue was KRW 34.47 billion with operating profit of KRW 0.69 billion (operating margin 2.0%), though net income was slightly negative at KRW -0.12 billion; in 2023 revenue fell to KRW 26.31 billion with an operating loss of KRW -1.29 billion (margin -4.9%), a net loss of KRW -0.39 billion, and cash flow from operations (CFO) deteriorating to KRW -1.39 billion.

In 2024 revenue rebounded to KRW 29.70 billion, operating profit turned positive at KRW 0.34 billion (margin 1.1%), net income improved to KRW 1.49 billion, and CFO improved to KRW 0.94 billion.

However, in 2025 revenue dropped sharply to KRW 18.38 billion year-on-year, the operating loss widened to KRW -1.93 billion (margin -10.5%), the net loss attributable to owners expanded to KRW -4.62 billion, and CFO turned negative again at KRW -0.47 billion.

By quarter, Q2 2025 revenue was KRW 6.29 billion with a temporary operating profit of KRW 0.21 billion, but Q3 2025 revenue fell sharply to KRW 3.00 billion with an operating loss of KRW -0.48 billion (Q4 2025 figures are not yet finalized and are excluded from this analysis).

In Q1 2026, revenue fell further to KRW 1.73 billion and the operating loss widened sharply to KRW -1.27 billion, with an owners' net loss of KRW -0.96 billion; according to a Seoul Economic Daily report dated May 15, 2026, this reflected weak sales in the core OLED supply model combined with non-recurring legal costs tied to the ownership dispute and R&D spending at EmergeLabs on solid-state battery materials.

Subsequently in Q2 2026, revenue rose substantially to KRW 4.41 billion from the Q1 level and the operating loss narrowed to KRW -0.27 billion, showing a directional improvement, though the owners' net loss remained at KRW -0.55 billion.

Some data suggests the OLED emitting materials market could grow at roughly a 7% compound annual rate through 2027, driven by expanding OLED adoption in AI smartphones, mid-tier models, automotive displays, and premium notebooks, though EM&I's own recent quarterly revenue trend has moved in the opposite direction with sharp declines.

Solid-state batteries, which use solid rather than liquid electrolytes to reduce fire and explosion risk, are seeing expanding application areas beyond electric vehicles into energy storage systems, urban air mobility, drones, humanoid robots, and smart wearable devices.

Solid electrolytes are categorized by material into oxide-based, sulfide-based, and polymer-based types; EM&I is focused on the oxide-based variant, and the company has indicated that initial commercialization is expected to occur first in wearables and IT devices before spreading to the US-centered electric vehicle market.

Heavy water, valued for its high thermal and chemical stability, is used across semiconductor and display processes, battery materials, and cosmetics/bio research as a strategic material with a constrained global supply chain, making it subject to government approval processes.

In terms of competitive positioning, the OLED materials segment is a mature industry competing against larger established materials makers, whereas the solid-state battery materials and heavy water businesses are still in early stages, where establishing mass-production capability first could confer an advantage.

The company has stated that final manufacturing and mass-production system construction for its oxide-based solid electrolyte is in its final stages, with major production equipment being brought in sequentially starting in July, and sample production for mass production planned to begin in September following equipment installation and trial runs.

Production targets are set to scale in stages, aiming for over 100kg of solid electrolyte this year and expanding the target to 600kg next year.

On the financing side, the company completed payment for its 15th round of convertible bonds worth KRW 1.5 billion, to be used for building a heavy water concentration plant and purchasing heavy water, and stated that its core heavy water concentration facility, with the largest processing capacity domestically, is scheduled for completion this year.

The heavy water business has cleared government approval by securing import-purpose confirmations from the Ministry of Trade, Industry and Energy and the Nuclear Safety and Security Commission, with the company indicating revenue was expected to begin in the first half of 2026.

In India, the company signed a lithium-ion cell supply agreement worth approximately $650,000 with ADVANTEX Battery LLP.

On the ownership front, the sale of control to an edtech-focused investment fund appears to have concluded in early August, with the executive leading the acquisition reportedly reviewing the construction of a next-generation edtech platform combining AI and robotics technology in partnership with one of Korea's three major education companies.

CEO Ko Chang-hoon stated in a shareholder letter that he intends to restore corporate value by leveraging technological competitiveness and new business initiatives.
