~ Record fiscal year revenue and earnings ~

Lake Oswego, Oregon, November 1, 2012 – The Greenbrier Companies (NYSE: GBX) today reported results for its fiscal fourth quarter and fiscal year ended August 31, 2012.

Fourth Quarter and Fiscal Year Highlights

William A. Furman, president and chief executive officer, said, “In fiscal 2012, our manufacturing operations responded well to strong demand for new railcars and our leasing operation significantly enhanced its syndication and management services model, leading to record revenue and earnings for the full year. While we realized positive momentum during the year in both of these operations, our fourth quarter earnings were well below our expectations. This was principally due to lower than anticipated new railcar deliveries, a high tax rate for the quarter, and certain employee related costs.”

Mark Rittenbaum, chief financial officer, noted, “New railcar deliveries to two customers totaling 560 railcars, with an aggregate value of nearly $50 million that we expected to occur by year-end, were postponed due to delays in a lease syndication transaction and one customer’s acceptance of certain railcars. All of these deliveries occurred subsequent to quarter end. Additionally, our actual tax rate for the quarter of 51% was significantly higher than our expected tax rate of around 34%. This difference was primarily due to a change in our geographic mix of earnings. Also, we incurred certain severance costs of nearly $1 million after-tax during the quarter. Finally, gain on disposition of equipment was only $.1 million pre-tax for the quarter, whereas the average gain for the prior three quarters was nearly $3 million per quarter.”

Furman concluded, “In fiscal 2013, we expect less business visibility than in fiscal 2012, as a result of global economic and geopolitical uncertainty. We will focus on four key areas beyond basic execution of our operating plan. First, we will expand capacity in higher margin railcar types, such as tank cars, to respond to market demand. Second, we will continue to expand our product offerings in the businesses that are related to the oil, gas and chemical industries and in other high-growth areas. Third, we will continue to improve our working capital position, increase free cash flow and pay down debt. Lastly, we will continue to seek diversification and growth opportunities in the rail freight marketplace, especially in leasing.”

Financial Summary

Segment Summary

Business Outlook

Given global economic and geopolitical uncertainty, Greenbrier currently has less business visibility and more variability now than it had in fiscal 2012. Based on current business trends and industry forecasts, management currently anticipates the Company’s new railcar deliveries in 2013 to be between 11,500 – 13,000 units. Approximately 7,300 of these units are in firm backlog as of August 31, 2012, with the balance of deliveries expected to come from additional orders received during the year. While the range of deliveries is below the 15,000 deliveries for fiscal 2012, the Company anticipates the product mix will include railcars with higher average selling prices. Currently, management anticipates that at the upper end of the delivery guidance range, fiscal 2013 revenue, adjusted EBITDA and earnings per share will be similar to fiscal 2012, with the second half of the year being stronger than the first half of the year.

Adjusted EBITDA is not a financial measure under generally accepted accounting principles (GAAP). We define Adjusted EBITDA as earnings attributable to Greenbrier before loss on extinguishment of debt, interest and foreign exchange, income tax expense, depreciation and amortization. Adjusted EBITDA is a performance measurement tool commonly used by rail supply companies and Greenbrier. You should not consider Adjusted EBITDA in isolation or as a substitute for other financial statement data determined in accordance with GAAP. In addition, because Adjusted EBITDA is not a measure of financial performance under GAAP and is susceptible to varying calculations, the Adjusted EBITDA measure presented may differ from and may not be comparable to similarly titled measures used by other companies.

Economic EPS is not a financial measure under GAAP. Economic EPS is used to measure the current economic impact of our Convertible Bonds due in 2018 that have a conversion strike price of $38.05/share, which exceeds our current stock price. We define Economic EPS as net earnings attributable to Greenbrier divided by the sum of weighted average basic common shares outstanding, plus the dilutive effect of warrants. This calculation excludes the dilutive effect of the shares underlying the 2018 bonds under the “if converted” method, which is included in the calculation of Diluted EPS. You should not consider Economic EPS in isolation or as a substitute for other financial statement data determined in accordance with GAAP. In addition, because Economic EPS is not a measure of financial performance under GAAP and is susceptible to varying calculations, the Economic EPS measure presented may differ from and may not be comparable to similarly titled measures used by other companies.
