Earnings Release

Greenbrier Reports Strong First Quarter Results

Q1 Diluted EPS of $1.72 and aggregate gross margin of 19.8%

Affirms FY 2025 guidance

Renews $100 million share repurchase authorization

The Greenbrier Companies, Inc. (NYSE: GBX) (“Greenbrier”), a leading international supplier of equipment and services to global freight transportation markets, today reported financial results for its first fiscal quarter ended November 30, 2024.

First Quarter Highlights

“Greenbrier achieved impressive results in the first quarter of fiscal 2025, delivering exceptional bottom-line performance and ROIC within our long-term range. The ongoing expansion of the lease fleet and the resulting recurring revenue is very encouraging. Our strong aggregate gross margin for the quarter was driven by a product mix weighted to more profitable railcar types and continued optimization in our manufacturing processes and capacity. We continue to streamline our business with the combination of our Manufacturing and Maintenance Services segments into one reportable segment, part of a strategic organizational alignment that commenced one year ago.” said Lorie L. Tekorius, CEO and President.

“While we observe demand easing slightly for certain railcar types and in some markets, we are affirming our full-year guidance and expect demand to increase as 2025 progresses. We are dedicated to executing our strategy to deliver strong performance, reduced cyclicality, and enhanced long-term shareholder value. Our results demonstrate our ability to thrive even in less than optimal business conditions. With a leading market position, a healthy backlog of new railcar orders, increasing predictability in growing areas of our business, and a continued focus on operational efficiencies, we anticipate sustainable results across various market conditions,” Tekorius concluded.

Business Update & Outlook

Effective September 1, 2024, the Company combined the Maintenance Services and Manufacturing segments into a single reportable segment, Manufacturing, to better reflect the Company’s comprehensive operations that allow it to streamline production processes and resources to better serve customers. Additionally, the Company renamed the Leasing & Management Services reportable segment to Leasing & Fleet Management to reflect the realignment of the Company’s organizational and reporting structure. These changes had no impact on the Company’s consolidated results of operations or financial position. Prior period segment results have been recast to reflect the Company’s new reportable segments.

Based on current trends and production schedules, Greenbrier is affirming its Operating Metric guidance and updating Capital Expenditure guidance for fiscal 2025:

SUPPLEMENTAL LEASING INFORMATION

(In millions, except owned fleet, unaudited)

Greenbrier’s leasing strategy provides an additional “go to market” element to Greenbrier’s Commercial strategy of direct sales, partnerships with operating leasing companies, and origination of leases for syndication partners as well as providing a platform for further growth at scale. Investing in leasing assets also provides a recurring stream of revenue and tax-advantaged cash flows, however in the short-term it reduces Greenbrier’s Manufacturing revenue and margin as a result of deferring revenue recognition.

During the April 2023 Investor Day, Greenbrier provided a long-term target to more than double recurring revenue from leasing and management fees by investing up to $300 million net annually for the next five years. Recurring revenue is defined as Leasing & Fleet Management revenue excluding the impact of syndication activity, which is more transactional in nature.

Forward-Looking Statements

This press release may contain forward-looking statements, including statements that are not purely statements of historical fact. Greenbrier uses words, and variations of words, such as “affect,” “anticipate,” “approximately,” “are,” “backlog,” “believe,” “drive,” “estimate,” “expect,” “grow,” “may,” “ongoing,” “position,” “recurring,” “result,” “schedule,” “strategy,” “strong,” “sustainable,” “target,” and similar expressions to identify forward-looking statements. These forward-looking statements include, without limitation, statements about our guidance and outlook, backlog and other orders, leasing performance, leasing strategy, financing, cash flow, tax treatment, and other information regarding future performance and strategies and appear throughout this press release. These forward-looking statements are not guarantees of future performance and are subject to certain risks and uncertainties that could cause actual results to differ materially from the results contemplated by the forward-looking statements. Factors that might cause such a difference include, but are not limited to, the following: an economic downturn and economic uncertainty; inflation (including rising energy prices, interest rates, wages and other escalators) and policy reactions thereto (including actions by central banks); disruptions in the supply of materials and components used in the production of our products; increased tariffs or import duties; labor disputes; loss of market share to other modes of freight shipment; and the war in Ukraine and related events. Our backlog of railcar units and other orders not included in backlog are not necessarily indicative of future results of operations. Certain orders in backlog are subject to customary documentation which may not occur. More information on potential factors that could cause our results to differ from our forward-looking statements is included in the Company’s filings with the SEC, including in the “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of the Company’s most recently filed periodic report on Form 10-K and subsequent Quarterly Reports on Form 10-Q. Except as otherwise required by law, the Company assumes no obligation to update any forward-looking statements or information, which speak as of their respective dates. Readers are cautioned not to place undue reliance on these forward-looking statements, which reflect management’s opinions only as of the date hereof.

Financial Metric Definitions

EBITDA is not a financial measure under generally accepted accounting principles (GAAP). This metric is a performance measurement tool used by rail supply companies and Greenbrier. You should not consider this metric in isolation or as a substitute for other financial statement data determined in accordance with GAAP. In addition, because this metric is not a measure of financial performance under GAAP and is susceptible to varying calculations, the measure presented may differ from and may not be comparable to similarly titled measures used by other companies.

We define EBITDA as Net earnings before Interest and foreign exchange, Income tax expense, Depreciation and amortization. We believe the presentation of EBITDA provides useful information as it excludes the impact of financing, foreign exchange, income taxes and the accounting effects of capital spending. These items may vary for different companies for reasons unrelated to the overall operating performance of a company’s core business. We believe this assists in comparing our performance across reporting periods.

ROIC is calculated by dividing the trailing four quarters of net operating profit after tax by the average trailing five quarters of total invested capital. Net operating profit after tax is defined as Earnings from operations, plus Earnings from unconsolidated affiliates, excluding the impact associated with items we do not believe are indicative of our core business or which affect comparability, less cash paid for income taxes, net. Total invested capital is defined as Revolving notes, plus Notes payable, plus Total equity, less cash in excess of $40 million. We believe ROIC is useful to investors as it quantifies how efficiently we generated operating income relative to the capital we have invested in the business.

These items may vary for different companies for reasons unrelated to the overall operating performance of a company’s core business. We believe this assists in comparing our performance across reporting periods.
