Hanover Compressor Company Reports Significant Improvement
in Operating Results for Second Quarter 2005

Hanover Compressor Company (NYSE: HC), a global market leader in full service natural gas compression and a leading provider of service, fabrication and equipment for oil and natural gas production, processing and transportation applications, today reported financial results for the quarter ended June 30, 2005.

Summary
Second quarter 2005 revenue increased to $344.8 million, an 18% increase over second quarter 2004 revenue of $292.9 million. EBITDA⁽¹⁾ from continuing operations for the second quarter 2005 was $80.3 million, a 6% increase over second quarter 2004 EBITDA of $75.9 million. The company’s second quarter 2005 EBITDA included approximately $5.4 million in foreign currency translation losses primarily related to the re-measurement of the company’s subsidiaries’ dollar-denominated inter-company debt and the strengthening of the U.S. Dollar relative to the Euro.

Earnings before income tax increased by $3.3 million to $154,000. Net loss for the second quarter 2005 was $6.4 million, or $0.07 per share, compared with a net loss of $9.1 million, or $0.11 per share, in the second quarter 2004.

“For the second straight quarter, Hanover’s operating results have improved markedly,” said John Jackson, President and Chief Executive Officer. “I am pleased that we are starting to see the results of our early efforts. Our focus on enhancing our results in the U.S. rental operations and fabrication is beginning to pay off. In the second half of 2005, we hope to expand revenues as we expect several international projects to come on-line. We continue to see attractive growth opportunities in the Latin America and Eastern Hemisphere markets. In the U.S. market, we remain focused on improving our returns on existing assets through operational efficiencies and improved pricing.”

U.S. rental revenue, gross profit and gross margin increased in the second quarter 2005 primarily due to continued improvement in market conditions that led to an improvement in pricing. Gross margin and gross profit also increased due to Hanover’s efforts to reduce maintenance and repair expense and improve pricing.

During the second quarter of 2005, international rental revenue increased, compared to the second quarter of 2004, due to increased rental activity, primarily in Mexico and Nigeria. Gross profit and gross margin decreased primarily due to start-up costs related to two projects in Nigeria and higher maintenance and repair expense. Second quarter 2004 gross profit and gross margin benefited from lower operating costs due to the timing of planned repair and maintenance activities scheduled in the second half of 2004.

Parts, service and used equipment revenue, gross profit and gross margin for the second quarter 2005 were higher than the same period a year earlier due primarily to used rental equipment and installation sales and improving market conditions.

Parts, service and used equipment includes two business components: parts and service; and used rental equipment and installation sales. For the second quarter 2005, parts and service revenue was $38.6 million with a gross margin of 27%, compared to $35.4 million and 28%, respectively, for the same period of 2004. Used rental equipment and installation sales revenue in the second quarter 2005 was $11.9 million with a gross margin of 32%, compared to $6.0 million and 2%, respectively, for the same period a year earlier. The company’s used rental equipment and installation sales and gross margin vary significantly from period to period and are dependent upon the exercise of purchase options on rental equipment by customers and the completion of new installation projects.

For the second quarter 2005, compression fabrication revenue declined due to decreased revenues in our high-spec compression business while gross profit increased, compared to 2004. Gross margin and gross profit improvement was due primarily to improved pricing and our focus on operational efficiencies. As of June 30, 2005, the company had compression and accessory fabrication backlog of approximately $67.5 million compared to $53.9 million at June 30, 2004.

Production and processing equipment fabrication revenue and gross profit for the second quarter 2005 increased over second quarter 2004 due to increased focus on fabrication sales and an improvement in market conditions, primarily in Latin America and the Eastern Hemisphere. The company continues to focus on improving its sales success ratio on new bid opportunities that has resulted in an improvement in our production and processing equipment fabrication revenues and gross profit. Production and processing equipment fabrication gross margin during the second quarter 2005 was positively impacted by approximately $1.7 million due primarily to the strengthening of the U.S. Dollar, relative to the Euro. Gross margin decreased due to the increase in revenues by our fabrication operations in Italy and Dubai, which typically have lower margins. As of June 30, 2005, Hanover had a production and processing equipment fabrication backlog of approximately $192.9 million compared to approximately $211.8 million at June 30, 2004.

Selling, general, and administrative expense (“SG&A”) for the second quarter 2005 was $43.9 million, compared to $41.9 million in the second quarter 2004. As a percentage of revenue, SG&A expense was 13% for the three months ended June 30, 2005 compared to 14% for the three months ended June 30, 2004.

Depreciation and amortization expense for the quarter increased to $45.5 million, compared to $43.3 million for the same period a year ago. Second quarter 2005 depreciation and amortization increased primarily due to additions to property, plant and equipment placed in service since June 30, 2004.

The company recorded a tax provision of $6.1 million for the second quarter of 2005 compared to $6.8 million for the second quarter of 2004. The company’s provision for income taxes for the second quarter of 2005 and 2004 does not include a tax benefit for the company’s tax losses in the U.S. and certain international jurisdictions. The company’s tax provision for the second quarter of 2005 benefited from the reversal of approximately $3.6 million in tax contingency reserves. These reserves were reversed because Hanover no longer believes these taxes will be incurred.

Liquidity and Other
Hanover had capital expenditures of approximately $28 million in the second quarter 2005, compared to approximately $20 million for the same period last year. At June 30, 2005, the company had approximately $1.69 billion in debt and compression equipment lease obligations compared to $1.78 billion at June 30, 2004. At June 30, 2005, borrowings include approximately $77 million outstanding under Hanover’s $350 million bank credit facility. The company had approximately $32 million in cash on its balance sheet at June 30, 2005.

Total compression horsepower at June 30, 2005 was 3,304,000, including 2,512,000 horsepower in the United States and 792,000 horsepower internationally. Hanover’s compression horsepower utilization rate as of June 30, 2005 on a total horsepower basis was approximately 83%, a 1% increase over December 31, 2004. U.S. and international utilization at June 30, 2005 was approximately 79% and 98%, respectively. At December 31, 2004, U.S. and international utilization was approximately 77% and 98%, respectively.

EBITDA from continuing operations consists of consolidated income (loss) from continuing operations before interest expense, provision for (benefit from) income taxes, and depreciation and amortization. We believe that EBITDA is a commonly used measure of financial performance for valuing companies in our industry. EBITDA should not be considered as an alternative to measures prescribed by generally accepted accounting principles and may not be comparably calculated from one company to another. Forward-looking information concerning Hanover’s 2005 net income (loss), which we believe is the most directly comparable GAAP financial measure to Hanover’s EBITDA is unavailable because the following items are significantly uncertain so as to make a 2005 prediction inadvisable: interest expense, foreign currency translation, taxes, depreciation and net results from and proceeds of the sale of our assets held for sale. The ultimate outcome of these uncertain items may have an impact on our net income (loss).
