"Negative effects from cost inflation for key inputs.... as well as energy and logistics... are becoming significantly more material," the supplier said in a statement on preliminary first-quarter results.
"In the event the geopolitical situation, in particular in Eastern Europe, remains tense or worsens, it could result in further lasting consequences for production, supply chains and demand," the supplier said.
Continental reported a first-quarter earnings margin of 4.7 percent, down from 8.5 percent last year, even as consolidated sales rose to 9.3 billion euros from 8.6 billion in the first quarter of 2021.
The supplier said it expected industry-wide production of passenger cars and light commercial vehicles to increase by just 4-6 percent year on year in 2022, down from its forecast of 6-9 percent in March.
As such, it expected its earnings margin for the year to be around 4.7-5.7 percent, down from its previous forecast of 5.5-6.5 percent.
Continental said on Tuesday it had temporarily resumed tire production for passenger cars at its plant in Russia on Tuesday after suspending it in early March following Russia's invasion of Ukraine, to protect local workers who could otherwise face criminal charges.
Continental, based in Hanover, Germany, ranks No. 6 on the Automotive News list of top 100 global suppliers, with 2020 sales to automakers of $29.7 billion.
