Founded in 1967, DH Autonex has a long corporate history; formerly known as Dayou Plus, it entered court-led rehabilitation in November 2023 after being affected by the collapse of its former parent, the Dayou Winia group, before joining DH Group in 2024 and adopting its current name in 2025.
The company operates three segments: an information and communications division covering network solutions and telecom equipment, an energy business division making EV chargers, and an automotive parts division producing LPG vehicle fuel tanks, hydrogen frames, and automotive haptic motors.
It entered the auto parts industry in 1998 with LPG fuel tank design and production, and using welding- and press-based manufacturing technology it supplies parts to Hyundai Motor, Kia, GM, and Hyundai Mobis, among other domestic and overseas automakers.
More recently, it has been expanding into future mobility components through development of ultra-low-temperature liquid hydrogen storage vessels and a product lineup based on carbon nanotube planar heating element technology.
The company's major shareholder group includes DH Global and other DH Group affiliates along with Chairman Lee Jeong-kwon of DH Group as related parties, and it is commercially linked to group affiliates such as steering-wheel maker DH Autolead.
The company has also been raising liquidity by divesting non-core assets, agreeing in early 2026 to sell land and a building in Chungju, North Chungcheong Province for KRW 7.6bn, with proceeds earmarked for future core business investment. This divested asset represented 11.5% of the company's total assets.
The rehabilitation process included the suspension of its Gwangju division's operations, but after the rehabilitation plan was approved the company retained its three-pillar business structure of communications, energy, and automotive parts.
