AMERICAN RAILCAR INDUSTRIES, INC. REPORTS RECORD REVENUE AND RAILCAR SHIPMENTS FOR SECOND QUARTER 2007

     St. Charles, MO, August 13, 2007 — American Railcar Industries, Inc. (“ARI” or the “Company”) [NASDAQ: ARII] today reported its second quarter 2007 financial results.

     For the three months ended June 30, 2007, revenues were $209.0 million and the net earnings attributable to common shareholders were $11.0 million or $0.52 per diluted share. In comparison, for the three months ended June 30, 2006, the Company had revenues of $151.6 million and net earnings attributable to common shareholders of $10.8 million or $0.51 per diluted share. During the three months ended June 30, 2007, the Company shipped 2,268 railcars compared to 1,734 railcars in the same period of 2006.

     Revenues increased in the second quarter of 2007 compared to the same period in 2006 primarily due to an increase in tank railcar shipments. The increase in shipments was a result of the recovery from low 2006 shipments, which resulted from the tank railcar facility shutdown for repair of tornado damages. This was partially offset by a reduction of covered hopper railcar shipments in the second quarter of 2007 compared to the same quarter of the prior year, reflecting a reduction in the number of covered hopper railcars ordered for delivery in the second quarter of 2007.

     EBITDA was $22.2 million in the second quarter of 2007 compared to $19.4 million in the second quarter of 2006. The increase in EBITDA in the second quarter of 2007 compared to the same period of 2006 resulted primarily from strength in our tank railcar business, partially offset by reduced covered hopper railcar shipments and an increase in selling, administrative and other expenses. A reconciliation of the Company’s net earnings to EBITDA (a non-GAAP financial measure) is set forth in the supplemental disclosure attached to this press release.

     For the six months ended June 30, 2007, revenues were $396.3 million and the net earnings attributable to common shareholders were $24.5 million or $1.15 per diluted share. In comparison, for the six months ended June 30, 2006, the Company had revenues of $330.3 million and net earnings attributable to common shareholders of $17.5 million or $0.87 per diluted share. During the six months ended June 30, 2007, we shipped 4,189 railcars compared to 3,714 railcars in the same period of 2006.

     Revenues increased in the six months ended June 30, 2007 compared to the same period in 2006 primarily due to an increase in tank railcar shipments, which was the result of the recovery from low 2006 shipments, which resulted from the tank railcar facility shutdown for repair of tornado damages, as well as the 2007 tank railcar capacity expansion. This was partially offset by a reduction of covered hopper railcar shipments for the six months ended June 30, 2007 compared to the same period of the prior year, reflecting a reduction in the number of covered hopper railcars ordered for delivery in the first six months of 2007.

     EBITDA was $47.0 million in the six months ended June 30, 2007 compared to $33.7 million in the six months ended June 30, 2006. The increases in net earnings attributable to common shareholders and EBITDA in the six months ended June 30, 2007 compared to the same period of 2006 resulted primarily from increased tank railcar shipments and improved manufacturing efficiencies. A reconciliation of the Company’s net earnings to EBITDA (a non-GAAP financial measure) is set forth in the supplemental disclosure attached to this press release.

     “The Company had a strong quarter, achieving record revenues and railcar shipments,” said James J. Unger, President and CEO of ARI. “Our substantial backlog of unfilled orders for new railcars totaled 14,043 railcars at June 30, 2007, which is down from the 16,473 railcars we had at December 31, 2006, but up from the 12,790 railcars at June 30, 2006. Our tank railcar lines are fully booked through 2008 and we have orders into 2009. The Company is pursuing a number of inquiries to fill our available future capacity for covered hopper railcars.”

     ARI will host a webcast and conference call on August 14, 2007 at 10:00 am (Eastern Time) to discuss the Company’s second quarter financial results. To participate in the webcast, please log on to ARI’s investor relations page through the ARI website

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 within 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, stock options and stock appreciation rights. 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.
