Joosung Corporation was established via corporate spin-off in 2009 and diversified its business through absorption mergers with Winitech in 2017 and RF Window in 2021, and the company trades on the KOSPI.
Historically the firm commercialized the world's first ICS mobile repeater and has supplied equipment to domestic carriers KT and LG Uplus as well as Japanese partners NTT DOCOMO and Denki Kogyo.
Its operations span three segments: telecom network (repeaters, UPS, MUX), customer products (vehicle black boxes, VPN security gear), and logistics (international freight forwarding).
In December 2023, Park Jin-su, a representative with 20 years of experience in international logistics, took control of the company through his family firm BNP Joosung, redirecting the business toward freight forwarding as a new growth pillar; this change of controlling shareholder was formally disclosed on August 10, 2026.
In 2024 the company also divested all five of its unlisted equity holdings as part of a selection-and-focus restructuring. As a result, the logistics forwarding segment's revenue share climbed to 84.5% as of the third quarter of 2025, giving the company a revenue structure that resembles a logistics firm in substance.
However, its official industry classification remains telecom and broadcasting equipment manufacturing, which observers say creates confusion between sector-based peer comparisons and the company's actual business mix.
In 2026 the company moved to internalize logistics revenue further by agreeing to acquire the parent's core freight-forwarding unit (annual revenue of about KRW 18.2 billion, roughly 21.3% of group sales) for KRW 20 billion.
