HANOVER COMPRESSOR REPORTS FOURTH QUARTER AND FULL
YEAR 2004 FINANCIAL RESULTS

HOUSTON, February 18, 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 processing and transportation applications, today reported financial results for the quarter and year ended December 31, 2004.

Summary
Fourth quarter 2004 revenue increased to $310.1 million, an 18% increase over fourth quarter 2003 revenue of $262.2 million.

EBITDA from continuing operations (consolidated income (loss) from continuing operations before interest expense, leasing expense, provision for (benefit from) income taxes, depreciation and amortization, and goodwill impairment) for the fourth quarter 2004 was $67.4 million, a 14% increase over fourth quarter 2003 EBITDA of $58.9 million. Due primarily to the weakening of the U.S. Dollar relative to the Euro, the company’s fourth quarter 2004 EBITDA included approximately $4.5 million in foreign currency translation gains related to the re-measurement of the company’s subsidiaries’ dollar denominated inter-company debt. In addition, the company’s production and processing equipment fabrication margin was negatively impacted by approximately $1.7 million due primarily to the weakening of the U.S. Dollar relative to the Euro and Canadian Dollar. Included in fourth quarter 2003 EBITDA was a $2.7 million non-cash charge to provide for the estimated cost of the securities-related litigation settlement.

Net loss for the fourth quarter 2004 was $20.2 million, or $0.24 per share compared with a net loss of $36.4 million, or $0.45 per share in the fourth quarter 2003. The company’s provision for income taxes for the fourth quarter of 2004 and 2003 did not include a full tax benefit for the company’s tax loss in the U.S. and certain international jurisdictions. The fourth quarter 2003 net loss also included $7.5 million in pre-tax charges for the estimated cost of securities-related litigation settlement, the write-off of deferred financing costs and the write-down of the company’s investment in discontinued operations.

For the year ended December 31, 2004, revenue increased to $1,188.6 million, an 11% increase over 2003 revenue of $1,075.1 million. EBITDA for 2004 increased to $293.0 million, a 31% increase over 2003 EBITDA of $223.1 million. For the year, Hanover recorded a net loss of $44.0 million, or $0.52 per share, compared to a net loss of $208.3 million, or $2.57 per share in 2003. Included in the 2004 net loss was a $4.0 million gain on the early cancellation of the note

that was issued as part of the securities-related litigation settlement. The net loss for 2003 included $250.6 million in pre-tax charges.

“While the fourth quarter 2004 was an improvement over the fourth quarter 2003, we are still not where we want to be in terms of operating performance” said John Jackson, President and Chief Executive Officer of Hanover. “In 2004, we continued to make progress in improving our operating performance as evidenced by our increased revenue and EBITDA and demonstrated capital discipline which allowed us to reduce leverage by approximately $149 million during the year. Going into 2005, we are focused on improving our operating margins and fleet utilization, reducing interest costs through continued debt reduction, and growing the business prudently, all with a focus on improving our return on capital deployed.”

Fourth quarter 2004 and the full year 2004 international rental revenue and gross profit increased, compared to the same periods a year earlier, due to increased compression and plant rental activity, primarily in Argentina, Brazil and Mexico. Hanover’s 2003 revenue and gross margin included approximately $2.7 million in fourth quarter 2002 revenue that was not recognized until 2003 due to concerns about the ultimate receipt as a result of the strike by workers of the national oil company in Venezuela.

Parts, service and used equipment revenue and gross profit for the fourth quarter 2004 was slightly lower than the same period a year earlier due primarily to lower used equipment sales partially offset by increased parts and service activity in the U.S. Parts, service and used equipment revenue includes two business components: parts and service; and used rental equipment and installation sales. For the fourth quarter 2004, parts and service revenue was $42.2 million with a gross margin of 22%, compared to $35.7 million and 26%, respectively, for the same period a year ago. Used rental equipment and installation sales revenue in the fourth quarter was $3.6 million with a gross margin of (17)%, compared to $11.3 million at a 3% gross margin 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 start of new projects by customers.

For the full year 2004, parts, service and used equipment revenue was higher than 2003 results due primarily to increased demand as a result of strong industry conditions. Parts and service revenue was $139.3 million with a gross margin of 24% for 2004, compared to $125.5 million in revenue with a gross margin of 29% in 2003. The decrease in margin in parts and service was primarily due to a decrease in margin in the company’s U.S. parts and service business, which has not performed as anticipated, and continues to be an area where the company is working to improve results. Used rental equipment and installation sales revenue was $41.1 million with a gross margin of 27% compared to $39.4 million with a gross margin of 14% in 2003.

For the fourth quarter and full year 2004, compression fabrication revenue and gross profit increased, compared to 2003, due primarily to increased sales activity. Gross margin in the fourth quarter 2004 was lower than the same period a year earlier due primarily to increased warranty expense.

Production and processing equipment fabrication revenue and gross profit for the fourth quarter 2004 increased over fourth quarter 2003 due to increased activity. Included in production and processing equipment fabrication revenue and expense for the fourth quarter 2004 was $36.9 million in revenue and $34.9 million in expense for Belleli, compared to $22.7 million in revenue and $19.8 million in expense for Belleli in the fourth quarter 2003. Production and processing equipment gross margin during the fourth quarter 2004 was negatively impacted by approximately $1.7 million due primarily to the weakening of the U.S. Dollar, relative to the Euro and the Canadian Dollar.

2004 production and processing equipment revenue was higher than 2003 revenue because of increased revenue at Belleli. Included in 2004 was $137.6 million in revenue and $124.2 million in expense for Belleli, compared to $116.8 million in revenue and $105.3 million in expense in 2003.

Selling, general, and administrative expense (“SG&A”) for the fourth quarter 2004 was $46.9 million, compared to $41.5 million in the fourth quarter 2003. Fourth quarter 2004 SG&A expense was negatively impacted by approximately $3.0 million in additional auditing and consulting expense for the implementation of Sarbanes-Oxley 404 and increased severance expense of $1.6 million during the quarter.

As a percentage of revenue, SG&A expense for 2004 was 15%, flat compared to 2003. SG&A expense in 2004 was $173.1 million compared to $159.9 million in 2003. The increase in SG&A expense for the year was due primarily to increased auditing and consulting expense for Sarbanes-Oxley of approximately $6.4 million, increased severance expense of approximately $2.3 million, and increased relocation and office start up expenses for new offices and personnel in Russia and increased municipal taxes due to increased business activity, primarily in Latin America.

Depreciation and amortization expense for the quarter increased to $46.4 million, compared to $44.8 million for the same period a year ago. Depreciation and amortization expense in the fourth quarter 2003 included $2.5 million to write-off deferred financing costs associated with the company’s old bank credit facility and compression equipment lease obligations that were refinanced in December 2003. Fourth quarter 2004 depreciation and amortization increased, compared to the same period a year ago, primarily due to increased depreciation expense due to additions to the rental fleet, including maintenance capital, placed in service during the year.

Depreciation and amortization expense for 2004 was $175.3 million, compared to $169.2 million in 2003. 2003 depreciation and amortization expense included a $14.3 million non-cash charge to write-down a portion of the company’s compression rental fleet. Depreciation and amortization expense increased in 2004, in comparison to 2003, due to additions to the rental

fleet, including maintenance capital, placed in service during the year and a full year of depreciation for the company’s ERP information system, which the company began depreciating in July 2003.

The company’s effective tax rate for the fourth quarter 2004 was (47)% compared to (130)% for the fourth quarter 2003. For 2004, Hanover’s effective tax rate was (84)%, compared to (3)% in 2003. Due to the company’s recent tax losses in certain jurisdictions (primarily U.S.), Hanover cannot reach the conclusion that it is “more likely than not” that certain of it’s deferred tax assets will be realized in the near future. Accordingly, the company’s provision for income taxes for the fourth quarter of 2004 did not include a full tax benefit for the company’s tax loss in the U.S. and certain international jurisdictions.

Financial results for the full year 2004 reflect the operations and the impact of the previously announced sale of the company’s Canadian compression rental assets and ownership interest in Collicut Energy Services Ltd. (“Collicut”) as discontinued operations. Prior period results have been reclassified to conform to the 2004 financial statement classification. The company sold its Canadian compression rental fleet, which as of September 30, 2004 consisted of approximately 84,000 horsepower. For the nine months ended September 30, 2004 this operation had approximately $14.9 million of revenue, EBITDA of approximately of $8.2 million and depreciation of approximately $2.7 million. The sale of the Canadian compression rental fleet and the company’s interest in Collicut resulted in a $2.1 million gain, net of tax.

Liquidity and Other
Hanover had capital expenditures of approximately $33 million in the fourth quarter 2004, compared to approximately $37 million for the same period last year. For 2004, Hanover had capital expenditures of approximately $90 million compared to $142 million in 2003. At December 31, 2004, the company had approximately $1.64 billion in debt and compressor lease obligations, including approximately $7 million outstanding under its $350 million bank credit facility and had approximately $38 million in cash on its balance sheet.

Total compression horsepower at December 31, 2004 was approximately 3,309,000, including approximately 2,551,000 horsepower in the United States and approximately 758,000 horsepower internationally. Hanover’s compression horsepower utilization rate as of December 31, 2004, on a total horsepower basis, was approximately 81.9%, an increase over utilization of approximately 81.5% at September 30, 2004 and 80.9% at December 31, 2003. U.S. and international utilization at December 31, 2004 was approximately 77.2% and 97.5%, respectively, compared to approximately 76.4% and 95.9%, respectively, at September 30, 2004, and approximately 76.1% and 94.4%, respectively, at December 31, 2003. Utilization percentages for periods prior to December 31, 2004 include the company’s Canadian compression rental fleet.

At December 31, 2004, Hanover’s third-party fabrication backlog, excluding Belleli, was approximately $141 million, a 204% increase from fourth quarter 2003 levels. Compared to the third quarter 2004, the company’s backlog, excluding Belleli, increased by approximately 22%. Backlog for Belleli at December 31, 2004 was approximately $150 million, compared to approximately $142 million at September 30, 2004 and $107 million at December 31, 2003.

(1) EBITDA from continuing operations consists of consolidated income (loss) from continuing operations before interest expense, leasing expense, provision for (benefit from) income taxes, depreciation and amortization and goodwill impairment. 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, 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.
