AMERICAN RAILCAR INDUSTRIES, INC. REPORTS RECORD REVENUE — NET
EARNINGS TO COMMON SHAREHOLDERS DOUBLE VERSUS FIRST QUARTER 2006

     St. Charles, MO, May 2, 2007 – American Railcar Industries, Inc. (“ARI” or the “Company”) [NASDAQ: ARII] today reported its first quarter 2007 financial results.

     For the three months ended March 31, 2007, revenues were $187.3 million and the net earnings attributable to common shareholders were $13.5 million or $0.63 per diluted share. In comparison, for the three months ended March 31, 2006, the Company had revenues of $178.7 million and net earnings attributable to common shareholders of $6.7 million or $0.35 per diluted share. Net earnings attributable to common shareholders for the first quarter of 2007 increased 102% over the same quarter in 2006.

     EBITDA was $24.9 million in the first quarter of 2007 compared to $14.3 million in the first quarter of 2006. Adjusted EBITDA was $25.5 million in the first quarter of 2007 compared to $17.9 million in the first quarter of 2006. The adjustment to EBITDA in the first quarter reflects $0.6 million of stock based compensation expense in 2007 compared to $3.6 million of stock based compensation expense in the first quarter of 2006.

     The increases in net earnings, EBITDA and Adjusted EBITDA in 2007 compared to 2006 resulted primarily from increased gross profit for our manufacturing operations, a decrease in selling, administrative and other expenses and a decrease in net interest expense. A reconciliation of the Company’s net earnings to EBITDA and Adjusted EBITDA (both non-GAAP financial measures) is set forth in the supplemental disclosure attached to this press release.

     Revenues increased in the first quarter of 2007 compared to the same period in 2006 primarily due to overall price increases and a shift in mix towards more expensive railcars. ARI shipped 1,921 railcars in the first quarter of 2007 compared to 1,980 in the first quarter of 2006. First quarter 2007 shipments were comprised of 1,177 covered hopper railcars and 744 tank railcars. In the first quarter of 2006, shipments were comprised of 1,527 covered hopper railcars and 453 tank railcars. The Company’s increase in tank railcar shipments in the first quarter of 2007 was primarily due to an increase in capacity at the Company’s Marmaduke tank railcar production complex as a result of a recently completed expansion. The Company experienced a decrease in covered hopper railcar shipments in the first quarter of 2007 primarily because of an increase in finished goods inventory of covered hopper railcars built against firm orders. These railcars are expected to ship in the second quarter of 2007.

     “The Company had a very strong quarter, achieving record financial results,” said James J. Unger, President and CEO of ARI. “Our substantial backlog of unfilled orders for new railcars totaled 14,623 railcars at March 31, 2007, which is approximately even with the backlog of 14,596 railcars we had at March 31, 2006, but down from the backlog of 16,473 railcars at December 31, 2006. Our tank railcar lines are fully booked into early 2009 but we currently have capacity available to satisfy covered hopper railcar demand in the second half of 2007.”

     ARI will host a webcast and conference call on Thursday May 3, 2007 at 10:00 am (Eastern Time) to discuss the Company’s first quarter financial results.

Forward Looking Statement Disclaimer

     This press release contains statements relating to our expected financial performance and/or future business prospects, events and plans that are “forward–looking statements” as defined under the Private Securities Litigation Reform Act of 1995. Forward-looking statements represent the Company’s estimates and assumptions only as of the date of this press release. Such statements include, without limitation, statements regarding estimated future production rates, estimated future manufacturing capacity and statements regarding any implication that the Company’s backlog may be indicative of future sales. These forward-looking statements are subject to known and unknown risks and uncertainties that could cause actual results to differ materially from the results described in or anticipated by our forward-looking statements. Estimated backlog reflects the total sales attributable to the backlog reported at the end of the particular period as if such backlog were converted to actual sales. Estimated backlog does not reflect potential price increases or decreases under our customer contracts that provide for variable pricing based on changes in the cost of certain raw materials and railcar components or the possibility that contracts may be canceled or railcar delivery dates delayed, and does not reflect the effects of any cancellation or delay of railcar orders that may occur. Other potential risks and uncertainties include, among other things: the cyclical nature of the railcar manufacturing business; adverse economic and market conditions; fluctuating costs of raw materials, including steel and railcar components, and delays in the delivery of such raw materials and components; ARI’s ability to maintain relationships with its suppliers of railcar components and raw materials; ARI’s ability to complete construction of its new flexible railcar plant in Marmaduke on a timely basis and with budget; fluctuations in the supply of components and raw materials ARI uses in railcar manufacturing; the highly competitive nature of the railcar manufacturing industry; the risk of further damage to our primary railcar manufacturing facilities or equipment; our reliance upon a small number of customers that represent a large percentage of our revenues; the variable purchase patterns of our customers and the timing of completion, delivery and acceptance of customer orders; our dependence on key personnel; the risks of labor shortage in light of our recent growth; the risk of lack of acceptance of our new railcar offerings by our customers; and the additional risk factors described in our filings with the Securities and Exchange Commission. We expressly disclaim any duty to provide updates to any forward-looking statements made in this press release, whether as a result of new information, future events or otherwise.

     EBITDA represents net earnings before income tax expense, interest expense (income), net of depreciation of property, plant and equipment. We believe EBITDA is useful to investors in evaluating our operating performance compared to that of other companies in our industry. In addition, our management uses EBITDA to evaluate our operating performance. The calculation of EBITDA eliminates the effects of financing, 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 business. EBITDA is not a financial measure presented in accordance with U.S. generally accepted accounting principles, or U.S. GAAP. Accordingly, when analyzing our operating performance, investors should not consider EBITDA in isolation or as a substitute for net earnings, cash flows from operating activities or other statements of operations or statements of cash flow data prepared in accordance with U.S. GAAP. Our calculation of EBITDA is not necessarily comparable to that of other similarly titled measures reported by other companies.

     Adjusted EBITDA represents EBITDA before elimination of stock based compensation expense related to a restricted stock grant and stock options. We believe that Adjusted EBITDA is useful to investors evaluating our operating performance compared to that of other companies in our industry. In addition, these charges are excluded from our calculation of EBITDA under our unsecured senior notes. Management also uses Adjusted EBITDA in evaluating our operating performance. Adjusted EBITDA is not a financial measure presented in accordance with U.S. GAAP. Accordingly, when analyzing our operating performance, investors should not consider Adjusted EBITDA in isolation or as a substitute for net earnings, cash flows from operating activities or other statements of operations or statements of cash flow data prepared in accordance with U.S. GAAP. Our calculation of Adjusted EBITDA is not necessarily comparable to that of other similarly titled measures reported by other companies.
