Volkswagen, Porsche, BMW, Mercedes-Benz and Ford are among auto makers that have been forced to cut production at their factories in Germany after supplies of wire harnesses, which form a key part of a car's electrical system, dried up.
"It is both impressive and moving how our employees are determined not to let the situation get the best of them but stand up for their country and for their way of life. Their safety and their lives are a top priority for us," Kamper said.
Wire harnesses are produced with plastic and rubber to organize and distribute wires throughout vehicles. Berlin-based Leoni has plants in Kolomyia, near the Romanian border, and Nezhukhiv, south of Lviv.
Some production is being relocated to Leoni plants in countries including Romania, Serbia, Slovakia, Tunisia, Egypt and Morocco, but the company and its automaker clients are committed to keeping Ukraine as a supplier, Kamper said.
Western Ukraine, with its low-cost, highly skilled work force and proximity to Europe's car factories and a wealth of raw materials, has grown into a major production hub for wire harnesses, with Japan's Fujikura and France's Nexans among those producing there, along with Leoni.
Leoni has 7,000 employees in Ukraine and 2,000 in Russia, and had expected to bring in a little less than $441 million in revenue from the two countries this year.
The company, which grew its revenue and earnings before interest and taxes last year despite rising logistics costs in the second half, expects lower revenue and earnings this year due to the impact of the war and wider supply chain disruptions.
Up to 15 percent of European auto production could be at risk because of shutdowns at wire-harness factories in Ukraine after the Russian invasion, Colin Langan, an auto analyst at Wells Fargo, said earlier this month.
