Leoni made all cables and powercords for Dell and Gateway 2000 during the dot-com boom of the 1990s in their plant in Birr, Offaly, Ireland, which was then moved to Slovakia. In Stryi and Kolomyia, both in Ukraine, the company produces wiring systems for the automotive industry. In 2022, as a result of the Russian invasion of Ukraine, production at these sites was halted, causing widespread production stops at European automobile factories.
