MAN SE is the third-biggest truck maker in Europe and the company has recently predicted its earnings margins and revenue would fail to soar this year because of a delivery slump triggered by financial trouble in its key markets. According to the Munich-based truckmaker, a division under the guidance of parent company Volkswagen AG - the second largest automaker in the world and the biggest in Europe - said that forecasted quotas of commercial vehicles and power-engineering orders would "slightly" dip below the sales level seen last year.
