Fiscal Year 2014 Highlights

Strategic Initiatives

William A. Furman, Chairman and CEO, said, “We leveraged our integrated business model to achieve our best annual performance yet and are well positioned to continue to grow in 2015 and beyond. We are obtaining the highest level of new orders in Greenbrier’s history. They are broad-based across many railcar types including tank cars, grain and sand covered hoppers, automotive, intermodal, boxcars, gondolas, and plastic pellet cars, among others. We also achieved record production levels and deliveries, all while improving operating efficiencies and enhancing our footprint in our manufacturing facilities. Our leasing business continues to grow and has been completely transformed into an asset-light model, as we syndicate increased volumes of leased railcars to multiple investors who have access to low-cost capital and who value Greenbrier’s products and services. Our owned lease fleet has contracted by $85 million and railcars under our management have increased by 13,000 units since we announced this strategic initiative in April 2013. Our combined actions produced manufacturing gross margins in the fourth quarter of 17.9%, a nearly six percentage point increase from last year. With a diverse backlog of 31,500 units, of which less than 40% are tank cars, we have good visibility stretching into our fiscal 2016.”

“We have refocused our Wheels, Refurbishment & Parts segment. Our 22 railcar repair shops and Watco’s 16 shops have been moved into GBW, where the scale of a 38-shop network and operational excellence will yield long-lasting competitive advantages. Demand for shop capacity and, in particular, tank car shop capacity to address the need for safe rail transport solutions is robust. The GBW network includes 14 shops specializing in tank car repair. Our wheels and parts business at a combined 13 locations is well positioned to produce growth, as the aftermarket for railcar wheels, parts and related services rises along with an expanding North American railcar fleet.”

“Looking ahead, we will continue our balanced approach to capital allocation among (i) investments needed to drive efficiency and margin improvement through our organization, (ii) growth capital; and, (iii) returning capital to shareholders through dividends and share repurchases. We will accelerate capital investments in 2015, which will drive operational efficiencies and complete previously announced capacity projects at our facilities in Mexico. These projects include the transitioning from one leased facility in Sahagun, Mexico to an owned facility in Tlaxcala, Mexico, a doubling of our tank car capacity with the flexibility to also build other railcar types on these lines and enhance vertical integration.”

“We continue to pioneer efforts to improve safety in the rail industry with our Tank Car of the Future design and investments in capacity at GBW to retrofit older legacy tank cars. Last month we filed comments with the U.S. Department of Transportation (USDOT), which we expect will issue a final rule on tank car standards by year end. We are confident that Washington will recognize Greenbrier’s Tank Car of the Future, as described in the USDOT’s proposed rule, as the best design for safer transportation of crude, ethanol and other flammables in North America and that GBW is well positioned to retrofit older legacy tank cars at an accelerated pace. Swift and appropriate action will help reinforce America’s longstanding priority to protect the public and preserve the natural environment, while taking care not to impede the economic prosperity associated with the energy renaissance in North America.”

“I am proud of our employees, our shared achievements together and our successful completion of the strategic initiatives we announced 18 months ago. I’m confident in the balanced and integrated approach our leaders are taking in each segment of our business in 2015, and that this approach will enhance shareholder value over the long term,” continued Furman.

Business Outlook

Furman concluded, “We ended August with over $505 million of liquidity from cash balances and available borrowings on revolving credit facilities. With a strong backlog, good industry fundamentals and positive outlook, we are investing in capital projects with high returns where we will quickly recoup

our investments. We are also pursuing growth opportunities in areas core to our business that will diversify our revenue base throughout the cycle. The future looks bright for Greenbrier. We remain committed to operational excellence in each of our businesses and enhancing the long-term trajectory of key metrics, such as gross margins, EBITDA and ROIC.”

Based on current business trends and industry forecasts in fiscal 2015, Greenbrier believes:

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.

In addition, the Company has established two new financial goals:

Net earnings excluding gain on contribution to GBW and restructuring charges, Adjusted EBITDA, and Diluted earnings per share excluding gain on contribution to GBW and restructuring charges are not financial measures under generally accepted accounting principles (GAAP). We define Net earnings excluding gain on contribution to GBW and restructuring charges as Net earnings before gain on contribution to GBW (after-tax) and restructuring charges (after-tax). We define Adjusted EBITDA as Net earnings attributable to Greenbrier before interest and foreign exchange, income tax expense, restructuring charges, gain on contribution to GBW and

depreciation and amortization. We define Diluted earnings per share excluding gain on contribution to GBW and restructuring charges as Net earnings excluding gain on contribution to GBW and restructuring charges before interest and debt issuance costs (net of tax) on convertible notes divided by Weighted average diluted common shares outstanding. Net earnings excluding gain on contribution to GBW and restructuring charges, Adjusted EBITDA, and Diluted earnings per share excluding gain on contribution to GBW and restructuring charges are performance measurement tools used by Greenbrier. You should not consider Net earnings excluding gain on contribution to GBW and restructuring charges, Adjusted EBITDA, and Diluted earnings per share excluding gain on contribution to GBW 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 gain on contribution to GBW 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 gain on contribution to GBW 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 gain on contribution to GBW and restructuring charges are reconciled as follows:

Diluted earnings per share 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.
