Lake Oswego, Oregon, October 31, 2013 – The Greenbrier Companies, Inc. (NYSE: GBX) today reported financial results for its fourth quarter and fiscal year ended August 31, 2013.

Fourth Quarter Highlights

Fiscal Year 2013 Highlights

Progress on Strategic Initiatives

William A. Furman, president and chief executive officer, said, “Our business performed well in 2013, notwithstanding weak markets for certain products such as double stack intermodal cars and marine barges, as well as other events, such as a low grain harvest due to drought. We hit our stride in Manufacturing, improved our Leasing model and took initial steps to address difficult conditions in our Wheels, Repair & Parts unit in order to achieve a record fourth quarter. In addition, we made meaningful progress on our previously announced strategic initiatives to enhance margins and liberate capital, which will grow return on invested capital (ROIC) and enhance shareholder value.”

“In Manufacturing, where we are improving margins, we continue to ramp tank car production for this high margin product and are approaching our goal of producing 16 units a day to meet strong demand. While we continue to benefit from participation in the energy markets, we remain focused on product diversification. This is reflected by the broad range of railcar types in backlog. More than half of our new railcar orders during the year were for non-energy uses, and in the fourth quarter, 22% of orders were for automotive-related products, including Multi-Max, our proprietary railcar featuring adjustable auto decks. “

“Our Leasing & Services business continues to deliver enhanced performance within our integrated business model. Through refinements to our leasing model, we are steadily increasing

transaction volumes through lease syndication and asset management. We are also reducing the permanent capital invested in this business, and increasing fee income. In the fourth quarter we realized proceeds of nearly $35 million from the sale of assets from our lease fleet, while retaining management of these assets. In the first quarter of 2014, we will continue this trend through the sale of additional lease fleet assets that we will continue to manage. Going forward, we will make further refinements to this business.”

“Improvements in operational efficiencies and margins in our Wheels, Repair & Parts segment represent a clear opportunity in 2014. We closed or sold four locations in 2013 and plan to close several more. The remaining underperforming facilities are implementing operational improvements, and we have negotiated more balanced commercial terms with select business partners. While fourth quarter results for this segment do not yet reflect these efforts, we expect to demonstrate better results in 2014. Overall, we are on-track to liberate $25 million of capital from this segment,” Furman continued.

Business Outlook

“The decisive actions we took to strengthen our operational performance and business strategy in 2012 and 2013 position us for growth in 2014. We have substantially met our capital efficiency goal of liberating at least $100 million of capital by February 2014 with more to come, and we are on track to improve gross margins to at least 13.5% by the fourth quarter of 2014,” Furman concluded.

Greenbrier believes its diverse product mix and integrated business model places the Company in a superior position during the current railcar cycle as overall transportation dynamics continue to improve. Based on current business trends and industry forecasts, in 2014 Greenbrier believes its:

Similar to previous years, financial results in the second half of the year are expected to be stronger than the first half. Also, while gross margins are expected to increase overall, management does not believe its track will be linear. Beginning next quarter, Greenbrier will disclose segment operating income.

Stock Repurchase Program

Greenbrier today announced that its Board of Directors has approved a $50 million share repurchase program to be executed over the next 18 months. Repurchases under the program will be made through open market transactions or through privately negotiated transactions from time-to-time, based on market conditions, legal and regulatory limitations and other factors. The Company is confident its balance sheet and liquidity will support this program, while it also continues to de-lever and take advantage of growth opportunities.

Net earnings excluding goodwill impairment and restructuring charges, Adjusted EBITDA, Adjusted weighted average diluted common shares outstanding and Diluted earnings per share excluding goodwill impairment and restructuring charges are not financial measures under generally accepted accounting principles (GAAP). We define Net earnings excluding goodwill impairment and restructuring charges as Net earnings (loss) attributable to Greenbrier before goodwill impairment (after-tax) and restructuring charges (after-tax). We define Adjusted EBITDA as earnings (loss) attributable to Greenbrier before interest and foreign exchange, income tax expense, goodwill impairment, restructuring charges and depreciation and amortization. We define Adjusted weighted average diluted common shares outstanding as Weighted average diluted common shares outstanding plus the dilutive effect of common stock equivalents related to warrants, restricted stock, restricted stock units and convertible notes to the extent that they are considered dilutive in the Diluted earnings per share excluding goodwill impairment and restructuring charges calculation. We define Diluted earnings per share excluding goodwill impairment and restructuring charges as Net earnings excluding goodwill impairment and restructuring charges before interest and debt issuance costs (net of tax) on convertible notes divided by Adjusted weighted average diluted common shares outstanding. Net earnings excluding goodwill impairment and restructuring charges, Adjusted EBITDA, Adjusted weighted average diluted common shares outstanding and Diluted earnings per share excluding goodwill impairment and restructuring charges are performance measurement tools used by Greenbrier. You should not consider Net earnings excluding goodwill impairment and restructuring charges, Adjusted EBITDA, Adjusted weighted average diluted common shares outstanding and Diluted earnings per share excluding goodwill impairment and restructuring charges in isolation or as a substitute for other financial statement data determined in accordance with GAAP. In addition, because Adjusted EBITDA and Diluted earnings per share excluding goodwill impairment and restructuring charges are not measures of financial performance under GAAP and are susceptible to varying calculations, the Adjusted EBITDA and Diluted earnings per share excluding goodwill impairment and restructuring charges measures presented may differ from and may not be comparable to similarly titled measures used by other companies.

Reconciliation of common shares outstanding and diluted earnings per share

The shares used in the computation of the Company’s basic and diluted earnings per common share and Diluted earnings per share excluding goodwill impairment and restructuring charges are reconciled as follows:

Diluted earnings per share excluding goodwill impairment and restructuring charges for the three months and year ended August 31, 2013 and the three months ended May 31, 2013 was calculated using the more dilutive of two approaches. The first approach includes the dilutive effect of outstanding warrants and shares underlying the 2026 Convertible notes in the share count using the treasury stock method. The second approach supplements the first by including the “if converted” effect of the 2018 Convertible notes issued in March 2011. Under the “if converted method” debt issuance and interest costs, both net of tax, associated with the convertible notes are added back to net earnings and the share count is increased by the shares underlying the convertible notes. The 2026 Convertible notes would only be included in the calculation of both approaches if the current stock price is greater than the initial conversion price of $48.05 using the treasury stock method.
