Net income was $19.6 million, or $0.60 per diluted share, in the prior year period.

Revenue was $253.0 million in the three months ended December 31, 2006, compared to $246.9 million in the three months ended September 30, 2006 and $224.8 million in the prior year period. EBITDA, as adjusted (as defined below), was $76.5 million in the three months ended December 31, 2006, as compared to $84.0 million in the three months ended September 30, 2006 and $74.5 million in the comparable period of the prior year.

For the twelve months ended December 31, 2006, net income was a record $87.7 million, or $2.82 per diluted share, including a charge of $1.1 million on a pretax basis related to debt extinguishment costs and a benefit of $3.2 million on a pretax basis related to employee benefit programs. Excluding these items, earnings per diluted share would have been $2.78 in 2006. For the twelve months ended December 31, 2005, net income was $50.9 million, or $1.56 per diluted share, including charges of $29.1 million on a pretax basis related to debt extinguishment and asset impairment costs.

For the twelve months ended December 31, 2006, revenue was $947.7 million and EBITDA, as adjusted, was $311.8 million, as compared to revenue of $807.3 million and EBITDA, as adjusted, of $262.7 million in the prior year period.

"I am pleased with our performance in 2006, which included record levels of revenue, EBITDA and earnings per share," commented Stephen A. Snider, Universal Compression Holdings' Chairman, President and Chief Executive Officer. "While the performance in each of our four business segments remains strong due to the continuing healthy demand for our products and services, recent labor and other cost increases have negatively impacted our domestic contract compression segment. We are currently addressing many of the issues related to these cost increases and believe that our proposed merger with Hanover Compressor Company will allow us to be in a position to further combat these cost pressures."

"We remain very enthusiastic about the recent announcement for Universal Compression Holdings and Hanover to combine in a merger of equals," added Snider. "We believe the merger will create a global leader in natural gas compression services and production and processing equipment and will enhance value for stockholders of both companies. We recently filed our initial application under the Hart-Scott-Rodino Antitrust Improvements Act, and we continue to expect the merger to close in the third quarter of this year."

"During the fourth quarter, we also pursued several activities of note," said Michael Anderson, Universal Compression Holdings' Senior Vice President and Chief Financial Officer. "We completed the initial public offering of Universal Compression Partners on October 20, 2006, raising in excess of $120 million of net proceeds. In connection with that transaction, we completed the refinancing of a significant amount of Universal Compression Holdings' debt, and put in place financing at Universal Compression Partners that provides a foundation to allow us to pursue our strategy of offering the remainder of our domestic contract compression business to Universal Compression Partners over time. We also completed the repurchase of almost 570,000 shares of Universal Compression Holdings' common stock in the quarter, at an average price of $63.30 per share. This share repurchase of approximately $36.1 million was completed under the $200 million share repurchase program previously authorized by Universal Compression Holdings' Board of Directors."

"Finally, in January 2007, we completed the purchase of B.T. Engineering Pte Ltd, a leading Singapore-based fabricator of oil and gas, petrochemical, marine and offshore equipment, including pressure vessels, FPSO process modules, terminal buoys, turrets, natural gas compression units and related equipment," Anderson continued. "We believe each of these activities has positioned Universal to continue to take advantage of the strong market conditions we see for all of our business segments."

Universal Compression Partners, L.P. Financial Results

For the three months ended December 31, 2006, Universal Compression Partners reported revenue of $13.5 million and net income of $2.7 million. In October 2006, Universal Compression Partners commenced operations upon the transfer of certain domestic contract compression assets from Universal Compression Holdings in connection with the initial public offering of Universal Compression Partners. For the quarter, EBITDA, as further adjusted for operating and selling, general and administrative cost caps provided by Universal Compression Holdings (as defined below), totaled $7.2 million and distributable cash flow (as defined below) totaled $5.0 million.

On February 2, 2007, Universal Compression Partners announced a cash distribution of $0.278 per unit. The distribution reflected the pro rata share of the partnership's minimum quarterly distribution of $0.35 per unit and covered the time period from the closing of the initial public offering through December 31, 2006. Based on this distribution, the distributable cash flow generated in the fourth quarter was approximately 1.40 times the amount of the cash distribution to unitholders. Excluding the effects of the cost caps provided by Universal Compression Holdings, distributable cash flow would have been sufficient to cover cash distributions to unitholders by approximately 1.26 times.

"We are pleased by Universal Compression Partners' successful initial public offering and the results from our first period of operations," commented Snider, Universal Compression Partners' Chairman, President and Chief Executive Officer. "As with the entirety of our contract compression business, our outlook is positive for Universal Compression Partners due to continuing strong demand for our services and sustainable growth prospects. Additionally, we believe that the proposed merger with Hanover will enhance the future growth for Universal Compression Partners as the combination provides a larger pool of domestic contract compression customers and equipment that can be offered for sale to Universal Compression Partners over time."

    (1) Management believes disclosure of EBITDA, as adjusted, and Gross
        Margin, non-GAAP measures, provide useful information to investors
        because, when viewed with our GAAP results and accompanying
        reconciliations, they provide a more complete understanding of our
        performance than GAAP results alone.  Management uses EBITDA, as
        adjusted, and Gross Margin as supplemental measures to review current
        period operating performance, comparability measures and performance
        measures for period to period comparisons.  In addition, EBITDA, as
        adjusted, is used by management as a valuation measure.

    (1) Management believes disclosure of EBITDA, as further adjusted for
        operating and selling, general and administrative cost caps provided
        by UCO, and Gross Margin, as adjusted for operating cost caps provided
        by UCO, non-GAAP measures, provide useful information to investors
        because, when viewed with our GAAP results and accompanying
        reconciliations, they provide a more complete understanding of our
        performance than GAAP results alone. Management uses EBITDA, as
        further adjusted for operating and selling, general and administrative
        cost caps provided by UCO, and Gross Margin, as adjusted for operating
        cost caps provided by UCO, as supplemental measures to review current
        period operating performance, comparability measures and performance
        measures for period to period comparisons.  In addition, EBITDA, as
        further adjusted for operating and selling, general and administrative
        cost caps provided by UCO, is used by management as a valuation
        measure.

    (2) Distributable cash flow, a non-GAAP measure, is a significant
        liquidity metric used by management to compare basic cash flows
        generated by us to the cash distributions we expect to pay our
        partners. Using this metric, management can quickly compute the
        coverage ratio of estimated cash flows to planned cash distributions.
