BANGALORE, July 7 (Reuters) - Greenbrier Cos Inc (GBX.N) posted a surprise quarterly profit, but said key customer GE (GE.N) had begun taking fewer railcar deliveries and added that it would furlough 550 more workers as it stops production at a Mexico facility.
Through Sept. 30, General Electric will accept 414 lesser railcars than what was agreed, Greenbrier said, adding that it believes GE to be in breach of its obligations under their existing contract.
"GE asserts that in subsequent periods they will accept for delivery an even smaller number of railcars. The seriousness of this problem to us accelerates during each fiscal quarter of fiscal 2010 and 2011," Greenbrier said.
GE intends to accept no more than 25 tank cars and 10 covered hopper cars per month from October 2009 to June 2010.
"Based on the production schedule originally proposed..., this is 95 fewer tank cars per month and 105 fewer covered hopper cars per month," Greenbrier said.
However, Greenbrier said the contract "contains adequate protection" and both the contract and law "provide effective legal and equitable remedies." It said it was attempting to work with GE to find a mutually acceptable solution.
Earlier this year, GE's Railcar Services Corp had indicated that it "desires to substantially reduce, delay or otherwise cancel railcar deliveries" under an eight-year contract to buy 11,900 railcars worth about $1.0 billion.
Greenbrier had said it would be forced to cut jobs if GE trimmed orders and had also called on members of the U.S. Congress for support, citing the potential job losses.
A contract termination would cost GE a significant settlement amount, hurt at least a thousand jobs and eat into more than three-fourth of Greenbrier's new railcar manufacturing backlog.
The employee count at Greenbrier, which said it would furlough the 550 workers mainly at its Concarril facility, is down to about 2,500 from a peak of about 5,000, Chief Financial Officer Mark Rittenbaum said on a conference call.
As of Aug. 31, 2008, it had 4,174 full-time employees, according to Greenbrier's 2008 annual report.
For the third quarter ended May. 31, Greenbrier reported a net loss of $50.5 million, or $3.00 per share, compared with a profit of $8.1 million, or 49 cents a share, a year ago.
However, excluding charges, it earned 3 cents a share.
Revenue fell 36 percent to $244.4 million.
Analysts on average expected third-quarter loss of 6 cents a share, before items, on revenue of $277.2 million, according to Reuters Estimates.
Greenbrier's new railcar manufacturing backlog as of May 31 was 14,100 units valued at $1.25 billion, sequentially down from 15,100 units at the end of the second quarter. About 11,800 units in backlog are subject to the GE contract.
"I'm skeptical about a quick recovery," Chief Executive William Furman said on a conference call about the railcar manufacturing business.
Railcar makers like Greenbrier and Trinity Industries (TRN.N), hit by declining freight volumes and falling demand in a weak economy, are depending on other businesses like aftermarket repair and wind tower manufacturing to survive.
"I think the car builders who don't have other diversified revenue bases are going to really feel the pain, because... our analysis is that most of the (industry railcar) backlog will be running out by the end of 2009," Furman added.
Shares of the Lake Oswego, Oregon-based company pared initial losses to trade down 6 percent at $6.50 in afternoon trade on the New York Stock Exchange. They had dropped almost 12 percent to a low of $6.11 earlier in the day. (Reporting by Eric Yep in Bangalore; Editing by Himani Sarkar)
