SM Bexel is an SM Group manufacturing affiliate operating both an automotive parts segment and a battery segment. According to a 2026Q1 disclosure, the automotive segment accounted for roughly 53.6% of revenue and the battery segment about 46.4%, splitting the business nearly evenly.
The automotive segment's main products are water pumps, auto parts, aluminum cylinder heads, and TCCM, with Hyundai Motor, Kia, Hyundai Mobis, and Hyundai Wia as key customers.
The battery segment is led by alkaline cells, followed by manganese cells and small-format ampoule cells used in defense applications, supplied to customers including Korea Defense Industry (KDI), Seobwon, Coupang, the military welfare unit, Emart, and Lotte Mart.
Since 2024 the company has supplied miniature ampoule cells for the Cheonmu unguided rocket system to KDI, completing the first phase of that supply by 2026Q1.
More recently, the company has expanded into lithium-ion battery packs and smart battery management systems (BMS) targeting drones, robots, and mobility, partnering with drone maker Volorand on delivery and agricultural spraying drone battery packs and supplying main and backup power packs for Soombi's cargo air vehicle (CAV).
The automotive segment is exposed to cost and pricing pressure typical of OEM parts supply, while the battery segment is pursuing differentiation through defense and specialty-use cells.
Because the two segments contribute similarly to revenue, both the auto production cycle and defense/specialty battery order flow affect overall results simultaneously.
