(AP) – Harley-Davidson announced a two-week suspension of vehicle assembly and most shipments, citing a regulatory compliance issue with one of its suppliers.

Shares tumbled almost 8% Thursday.

The decision was made Wednesday “out of an abundance of caution” after the company received information from a supplier of one of its component parts, Harley-Davidson said. The company did not name the supplier or provide details on the part in question and said the assembly and shipping suspension would not affect its LiveWire electric motorcycle.

The company, like most global manufacturers, was already struggling with supply issues. It reported in April that its profit was trimmed by rising costs and chip shortages, which hurt sales in North America.

Harley-Davidson shares have lost nearly one-third of their value in the past year and Thursday, stock in the Milwaukee company fell $2.76 to $32.97.

A Harley-Davidson spokesperson referred abc27 to the company’s original statement when asked about the York plant’s status.
