Hyundai Mobis operates in two broad areas: modules and core parts (electrification, parts manufacturing, module assembly) and aftermarket parts distribution.
In the provisional Q2 2026 results released on 24 July 2026, aftermarket revenue was KRW 3.430tn and module/core-parts revenue was KRW 12.894tn, showing that most sales come from modules and core parts while the aftermarket generates the profit.
The company has explained that in 2025 margin improvement was led by the aftermarket business, while the module and core-parts business, comprising electrification, parts manufacturing and module assembly, supported growth through higher sales and a swing back to an operating profit.
The customer base is centred on Hyundai Motor and Kia, but non-captive expansion is the strategic core: at its 2024 CEO Investor Day the company said it had won overseas brands including Volkswagen, Stellantis, BYD and Mahindra as customers, with parts-manufacturing orders rising from USD 1.8bn in 2020 to about USD 9.2bn in 2024.
In Europe, the Kecskemet module plant in Hungary began operating in March 2026 to supply chassis modules for Mercedes-Benz electrified models, and a new battery system (BSA) plant was built in Navarra, Spain for Volkswagen electric vehicles.
Product pillars are electrification components such as battery systems and PE systems, electronics including integrated controllers and infotainment, and chassis/safety products such as electronic braking and steering.
Restructuring is running in parallel: in January 2026 the company signed an MOU with France-based OPmobility for a transaction covering its lamp business, and reports also point to a review of the bumper business sale, the sale of a Gyeongju logistics centre, and discussions on selling Ohio battery-system facilities to customer Stellantis.
One analysis noted that parts businesses such as lamps and bumpers accounted for roughly 23.3% (KRW 14.213tn) of 2025 total revenue of KRW 61.118tn, so the scale of the reshuffle is not trivial.
Competition centres on non-captive order contests with global mega-suppliers such as Bosch, Denso, Continental and Magna, with a newer axis in mass supply of actuators for Boston Dynamics humanoid robots and an SDV/ADAS partnership with Qualcomm.
