TUI, a publicly owned company headquartered in Germany, was founded in 1923 and employs approximately 35,340 individuals. Functioning as a multinational leisure, travel, and tourism company, it operates as an integrated tourism business. Originally established as Preussag AG, a state-owned German mining and industrial conglomerate, the enterprise divested its heavy industry assets in the late 1990s to pivot into the service and hospitality sectors. The group controls an end-to-end holiday supply chain that spans source-market travel agencies, digital booking platforms, and physical holiday assets.
