Supply chain impacts could also be seen, with deliveries from suppliers in Ukraine being limited. The lack of critical car parts has already forced Volkswagen, along with other German carmakers, to curtail production at some plants, while exports to Russia have been halted. The course of the war and the impact on Volkswagen "cannot be predicted with sufficient certainty" but risked having a "negative impact" on the Wolfsburg-based group. Volkswagen also said it delivered some 500,000 fewer cars in the first quarter of 2022 than in the previous year, a 22-percent drop. The continued impact of the coronavirus pandemic, which has recently led to widespread lockdowns in China, a key market, also loomed over the auto manufacturer's future performance. As did the possibility of further disruption to supply chains "especially for semiconductors", a key component in both conventional and electric vehicles. The two effects already conspired to make business difficult for Volkswagen in 2021.
