FRANKFURT (Reuters) – Daimler AG (DE:)’s truck business, the world’s largest, has seen the supply of crucial chips tighten further in recent weeks, the division’s chief executive said in a Frankfurter Allgemeine Sonntagszeitung report.

Martin Daum stated to the weekly newspaper that “the situation has intensified once again” since the summer months. This had also affected the production in Germany as well as the United States.

The interview was excerpted on Friday and published on Sunday.

Daum stated that orders books had been filled, but stockpiles were rising due to shortages which hit major carmakers.

There are large inventories of vehicles that have been produced, but the essential components are not available. These vehicles are urgently needed by our customers. While we’d love to be able to supply the vehicles, we still need them.

Daum indicated that tightening supply may have an impact on third-quarter unit sales. However, he said there were no signs of rapid recovery. The issue will remain in place for the sector for a while.

Daimler (OTC) Truck Holding AG will become separate from Daimler in the latter part of this year. Shareholders are expected to vote at an extraordinary general assembly on October 1. Daimler will then be renamed Mercedes-Benz Group AG.
