MILAN (Reuters) - Italy's Leonardo said its former sub-contractor Manufacturing Processes Specification (MPS) did not provide it with components for Airbus' programmes.
Shares of the Italian state-controlled conglomerate fell more than 7% on Thursday after Boeing said parts supplied by Leonardo sourced from the sub-contractor had been improperly manufactured.
MPS is listed as an Airbus approved supplier in a document available on the planemaker's website.
Leonardo shares were volatile on Friday on the Milan stock exchange. They were rising 1% at 1255 GMT, underperforming Italy's blue-chip index FTSE MIB, up 0.8%.
