Elcomtec, founded in 1991 and listed on KOSDAQ, historically operated three business segments: handset camera module lenses, LED lighting, and EMS (electronics manufacturing services).
In June 2025, however, the company announced through a regulatory filing that it would discontinue production and sale of handset camera lenses, citing weak industry conditions and intensifying price competition among rivals.
At the time, the company explained that lens revenue had been declining every year while the EMS segment had been growing, so the impact of halting the lens business would be limited.
Following this, the business structure was reorganized around EMS, with the flagship product being LED light sticks used at concerts and fan meetings, small electronic devices combining LED light sources, wireless control modules, and circuit boards.
As of the first quarter of 2026, EMS accounted for 85.7% of total revenue. Industry observers widely believe the specific customer driving this growth is HYBE, whose revenue from Elcomtec grew 3.7 times quarter over quarter.
Manufacturing is carried out through the Pyeongtaek headquarters and plant, a China Yantai subsidiary, and a Vietnam injection-molding supply chain, with in-house capability spanning mold-making, injection molding, surface-mount technology (SMT), and assembly and inspection, an advantage cited in the cost-competitive EMS industry.
The largest shareholder is KOSDAQ-listed component maker Partron, and the company is pursuing diversification into automotive electronics components in collaboration with its parent, while also conducting resource development through affiliate AGM Mining in Mongolia, including gold and copper exploration.
