Railroad equipment supplier Greenbrier Cos Inc posted third-quarter results well below market estimates, hurt by a temporary shortage of castings in North America and a delay in certification of railcars in Europe.

Greenbrier, however, said it remains on track to achieve its fiscal 2011 targets and forecast higher revenue and EBITDA in the fourth quarter, compared with the third quarter.

For the third quarter, net loss attributable to Greenbrier was $3.3 million, or 14 cents a share, compared with net earnings of $4.6 million, or 23 cents a share, a year ago.

On an adjusted basis, it earned 10 cents a share.

Quarterly sales rose to $317.3 million from $207.4 million.

Analysts, on average, were expecting earnings of 21 cents a share, before special items, on revenue of $370.6 million, according to Thomson Reuters I/B/E/S.
