BUCYRUS INTERNATIONAL, INC. ANNOUNCES SUMMARY OPERATING RESULTS FOR THE THREE AND SIX MONTHS ENDED JUNE 30, 2007

______________________________________________________________________

South Milwaukee, Wisconsin – August 2, 2007 - Bucyrus International, Inc. (NASDAQ: BUCY), one of the world's leading manufacturers of large-scale excavation equipment used in surface mining, and a leading designer, manufacturer and marketer of high technology system solutions for underground coal mining as a result of its recent acquisition of DBT GmbH (“DBT”), announced today its summary unaudited results for the three and six months ended June 30, 2007. Bucyrus acquired DBT on May 4, 2007 for $710 million in cash, subject to certain post-closing adjustments, and 471,476 shares of Bucyrus’ common stock with a market value of $21.8 million.

Second Quarter Operating Results

The net assets acquired and results of operations of DBT since the date of acquisition are included in Bucyrus’ financial information presented below which, as a result of the shortened reporting period, may not be indicative of future results.

Sales for the second quarter of 2007 were $374.8 million, an increase of $193.0 million, or 106.2%, from $181.8 million for the second quarter of 2006. Original equipment sales were $189.0 million, an increase of $135.2 million, or 251.6%, from $53.8 million for the second quarter of 2006. Aftermarket parts and service sales were $185.8 million, an increase of $57.8 million, or 45.1%, from $128.0 million for the second quarter of 2006. Sales for the six months ended June 30, 2007 were $565.2 million, an increase of $217.7 million, or 62.7% from $347.5 million for the six months ended June 30, 2006. Original equipment sales were $267.4 million, an increase of $160.2 million, or 149.4%, from $107.2 million for the six months ended June 30, 2006. Aftermarket parts and service sales were $297.8 million, an increase of $57.5 million, or 23.9%, from $240.3 million for the six months ended June 30, 2006. Surface mining sales for second quarter of 2007 were $213.6 million, an increase of $31.8 million, or 17.5%, from $181.8 for the second quarter of 2006. Surface mining original equipment sales were $85.7 million, an increase of $31.9 million, or 59.5%, from $53.8 million for the second quarter of 2006, and aftermarket parts and service sales were $127.9 million, a decrease of $.1 million, or .1%, from $128.0 million for the second quarter of 2006. Surface mining sales for the six months ended June 30, 2007 were $404.0 million, an increase of $56.5 million, or 16.3%, from $347.5 million for the six months ended June 30, 2006. Surface mining original equipment sales were $164.1 million, an increase of $56.9 million, or 53.1%, from $107.2 million for the six months ended June 30, 2006, and aftermarket parts and service sales were $239.9 million, a decrease of $.4 million, or .2%, from $240.3 million for the six months ended June 30, 2006. The overall increase in surface mining sales is the result of sustained demand and increased prices of commodities that are surface mined by Bucyrus machines. Capacity constraints continue to have an impact on surface mining sales. The ongoing expansion of Bucyrus’ South Milwaukee facilities is expected to be completed by the first quarter of 2008. Underground mining sales for the second quarter and first six months of 2007 were $161.2 million and consisted of $103.3 million and $57.9 million of original equipment and aftermarket parts and service sales, respectively. Underground mining sales were at the level expected when DBT was acquired.

Gross profit for the second quarter of 2007 was $96.3 million, or 25.7% of sales, compared with $46.9 million, or 25.8% of sales, for the second quarter of 2006. Gross profit for the six months ended June 30, 2007 was $148.4 million, or 26.3% of sales, compared with $87.8 million, or 25.3% of sales, for the six months ended June 30, 2006. Gross profit for the second quarter and first six months of 2007 was reduced by $6.2 million of amortization of purchase accounting adjustments as a result of the acquisition of DBT. Excluding this amortization, the gross profit percentage for the second quarter and first six months of 2007 in each case would have been 27.3%. The increases in gross profit were primarily due to the acquisition of DBT and increased surface mining original equipment sales, as well as improved gross margins on both surface mining original equipment and aftermarket parts and services.

Selling, general and administrative expenses for the second quarter of 2007 were $42.9 million, or 11.5% of sales, compared with $18.1 million, or 9.9% of sales, for the second quarter of 2006. Selling, general and administrative expenses for the six months ended June 30, 2007 were $64.1 million, or 11.3% of sales, compared with $33.5 million, or 9.7% of sales, for the six months ended June 30, 2006. The increase in selling, general and administrative expenses was primarily due to the acquisition of DBT. Excluding the impact of the acquisition of DBT, the dollar amount of selling, general and administrative expenses in the second quarter of 2007 approximated the dollar amount of selling, general and administrative expenses recognized in recent quarters.

Operating earnings were $44.3 million for the second quarter of 2007, an increase of 74.7% from $25.4 million for the second quarter of 2006. Operating earnings for the six months ended June 30, 2007 were $72.2 million, an increase of 49.2% from $48.4 million for the six months ended June 30, 2006. Included in second quarter and first six months operating earnings for 2007 was $11.5 million related to the operations of DBT, which is net of $10.5 million of purchase accounting adjustments. In addition to operating earnings related to DBT operations, operating earnings for the quarter and six months ended June 30, 2007 increased primarily due to increased gross profit resulting from increased sales volume.

Interest expense was $7.0 million for the second quarter of 2007 compared with $.6 million for the second quarter of 2006. Interest expense for the six months ended June 30, 2007 was $8.4 million compared with $1.2 million for the six months ended June 30, 2006. The increase in interest expense in 2007 was due to increased debt levels related to the financing of the acquisition of DBT.

Income tax expense for the second quarter of 2007 was $11.0 million compared with $3.2 million for the second quarter of 2006. Income tax expense for the six months ended June 30, 2007 was $19.6 million compared with $11.0 million for the six months ended June 30, 2006. The effective rate for the second quarter of 2007 was 28.3%, which is lower than the statutory rate as a result of the implementation of the financing structure and certain one-time adjustments related to the acquisition of DBT. Income tax expense for the second quarter of 2006 was reduced by a net income tax benefit of approximately $3.7 million related to foreign tax credits. The foreign tax credits resulted from the completion of Bucyrus’ evaluation of its potential to claim additional foreign tax credits generated in previous tax periods.

Net earnings for the second quarter of 2007 were $27.8 million, or $.81 per share, compared with $21.6 million, or $0.69 per share, for the second quarter of 2006. Net earnings for the six months ended June 30, 2007 were $45.6 million, or $1.39 per share, compared with $36.1 million, or $1.15 per share, for the six months ended June 30, 2006.

EBITDA for the second quarter of 2007 was $57.7 million, an increase of 98.4% from $29.1 million for the second quarter of 2006. As a percent of sales, EBITDA for the second quarter of 2007 was 15.4% compared to 16.0% for the second quarter of 2006. EBITDA for the six months ended June 30, 2007 was $89.8 million, an increase of 61.3% from $55.7 million for

the six months ended June 30, 2006. As a percent of sales, EBITDA for the six months ended June 30, 2007 was 15.9% compared to 16.0% for the six months ended June 30, 2006. Included in second quarter and first six months EBITDA for 2007 was $20.3 million related to the operations of DBT. EBITDA is defined as net earnings before interest income, interest expense, income taxes, depreciation and amortization. EBITDA includes the impact of non-cash stock compensation expense, severance expenses, loss on sales of fixed assets and the inventory fair value purchase accounting adjustment charged to cost of products sold as set forth in the following tables. EBITDA is a measurement not recognized in accordance with accounting principles generally accepted in the United States of America (GAAP) and should not be viewed as an alternative to GAAP measures of performance. For a reconciliation of net earnings as shown in the Unaudited Consolidated Statements of Earnings to EBITDA and a reconciliation of net cash provided by operating activities as shown in the Unaudited Consolidated Statements of Cash Flows to EBITDA, see the tables below.

Capital expenditures for the first six months of 2007 were $35.6 million, which included $16.8 million related to Bucyrus’ previously announced ongoing expansion of its South Milwaukee facilities. The remaining capital expenditures consisted primarily of production machinery at its main manufacturing facility.

As of June 30, 2007, total backlog was $1.46 billion, $1.13 billion of which was expected to be recognized within the subsequent 12 months. This represents a 63.6% and 90.8% increase from the December 31, 2006 total backlog of $894.7 million and 12-month backlog of $593.8 million, respectively. Included in backlog at June 30, 2007 was $994.6 million related to surface mining operations, $667.4 million of which was expected to be recognized within the subsequent 12 months, and $469.1 million related to underground mining operations, $465.5 million of which was expected to be recognized within the subsequent 12 months. New orders related to surface mining operations for the first six months of 2007 were $298.5 million and $205.3 million for original equipment and aftermarket parts and service sales, respectively. New orders related to underground mining operations for the first six months of 2007 were $127.3 million and $62.2 million for original equipment and aftermarket parts and service sales, respectively. Included in surface mining original equipment orders for the second quarter of 2007 was the sale of a dragline and related equipment with a price in excess of $100.0 million to be delivered by 2010. Since Bucyrus recognizes revenue on a percentage of completion basis, the impact of this order will be recognized over a period of several years.

__________________

(1)

EBITDA is defined as net earnings before interest income, interest expense, income tax expense, depreciation and amortization. EBITDA is presented because (i) management uses EBITDA to measure the company’s liquidity and financial performance and (ii) management believes EBITDA is frequently used by securities analysts, investors and other interested parties in evaluating the performance and enterprise value of companies in general, and in evaluating the liquidity of companies with significant debt service obligations and their ability to service their indebtedness. The EBITDA calculation is not an alternative to operating earnings under accounting principles generally accepted in the United States of America, or GAAP, as an indicator of operating performance or of cash flows as a measure of liquidity. Additionally, EBITDA is not intended to be a measure of free cash flow for management’s discretionary use, as it does not consider certain cash requirements such a interest payments, tax payments and debt service requirements. Because not all companies use identical calculations, this presentation of EBITDA may not be comparable to other similarly titled measures of other companies. The following table reconciles net earnings and net cash provided by operating activities..

(2)	Reflects non-cash stock compensation expense related to Bucyrus’ equity incentive plans.

(3)	Reflects severance expenses for personnel changes in the ordinary course.

(4)	Reflects losses on the sale of fixed assets in the ordinary course.

(5)	In connection with the acquisition of DBT, inventories purchased were adjusted to estimated fair value. This adjustment is being charged to cost of products sold as the inventory is sold.
