DY A was founded in 1960, changed its name to Dayou A-tech in 2010, and later renamed itself DY A; it is a KOSPI-listed automotive seat specialist.
Its Gwangju seat division exclusively supplies seats for the Sportage, Seltos, EV5 and Bongo truck to Kia's Gwangju plant, while also supplying Casper seats to Gwangju Global Motors (GGM).
New vehicle awards for the PV7 and the next-generation Kona are prompting the company to expand its business into the Insan and Ulsan plants.
The company carried out a 5-for-1 share consolidation on August 27, 2026, adjusting the share counts held by largest shareholder Park Young-woo, executives, relatives, and affiliates TPC, Dayou Haneul and Youngil, while their combined stake held steady at 45.24%.
In the past, the company sat at the core of the Dayou Winia Group's auto-parts lineup, spanning aluminum wheel materials, steering wheels and plastic parts through affiliates, but during the group's 2023 liquidity crisis it fully divested stakes in loss-making subsidiaries to restructure its business.
A notable example was the sale of a 37.66% stake in steering-wheel maker Dayou AP to DH Global. Following this slimming-down, the company is now a more focused seat-and-pad manufacturer.
Because its customer base is concentrated in Kia's Gwangju plant and GGM—itself tied to the Hyundai-Kia group—earnings are closely linked to automaker production plans and new-model allocations.
