HOUSTON, May 9 /PRNewswire-FirstCall/ -- Universal Compression Holdings, Inc. (NYSE: UCO) and Universal Compression Partners, L.P. (Nasdaq: UCLP) today reported earnings for the first quarter of 2007.

Universal Compression Holdings, Inc. Financial Results

Universal Compression Holdings reported net income of $14.3 million, or $0.46 per diluted share, in the three months ended March 31, 2007, including a charge of $1.4 million on a pretax basis for merger-related expenses. Excluding this charge, earnings per diluted share would have been $0.49. Net income was $20.0 million, or $0.64 per diluted share, in the three months ended December 31, 2006, including a charge of $1.1 million on a pretax basis related to debt extinguishment costs. Excluding this charge, earnings per diluted share would have been $0.67 in the fourth quarter of 2006. Net income was $20.9 million, or $0.68 per diluted share, in the prior year period.

Revenue was $239.4 million in the three months ended March 31, 2007, compared to $253.0 million in the three months ended December 31, 2006 and $229.1 million in the prior year period. EBITDA, as adjusted (as defined below), was $72.3 million in the three months ended March 31, 2007, as compared to $76.5 million in the three months ended December 31, 2006 and $76.0 million in the comparable period of the prior year.

"We continued to experience solid demand in each of our business segments in the first quarter although, as expected, field and administrative cost pressures continued to be a challenge," commented Stephen A. Snider, Universal Compression Holdings' Chairman, President and Chief Executive Officer. "With our ongoing investment in people and infrastructure, such as our October 2006 IPO of Universal Compression Partners and January 2007 acquisition of BT Engineering, we believe we are building a solid foundation to continue the growth of our company. Our business outlook remains optimistic due to existing market conditions, healthy overall company activity levels, including the scheduled completion of significant fabrication projects in the second quarter, ongoing initiatives to improve field operating efficiencies and our proposed merger with Hanover Compressor Company."

Merger Update

On March 27, 2007, Universal Compression Holdings and Hanover Compressor Company jointly announced that they had received a request for additional information from the Antitrust Division of the U.S. Department of Justice regarding the proposed merger between the companies. Universal is cooperating with the government with respect to that request and continues to expect the transaction to close in the third quarter of 2007.

Universal Compression Partners, L.P. Financial Results

Universal Compression Partners reported revenue of $17.6 million and net income of $2.3 million in the three months ended March 31, 2007, compared to revenue of $13.5 million and net income of $2.7 million in the three months ended December 31, 2006. Universal Compression Partners commenced operations in October 2006 upon the contribution of certain domestic contract compression assets from Universal Compression Holdings in connection with the initial public offering of Universal Compression Partners. EBITDA, as further adjusted (as defined below), totaled $9.5 million in the three months ended March 31, 2007 compared to $7.3 million in the three months ended December 31, 2006. Distributable cash flow (as defined below) totaled $6.0 million in the three months ended March 31, 2007 compared to $5.2 million in the three months ended December 31, 2006. Because Universal Compression Partners completed its initial public offering on October 20, 2006, the three month period ended December 31, 2006 only included results from operations from that date. Universal Compression Partners' results for the three months ended March 31, 2007 included its first complete quarter of operations.

On April 30, 2007, Universal Compression Partners announced a cash distribution of $0.35 per unit, which reflected the partnership's minimum quarterly distribution, compared to its previous cash distribution of $0.278, which represented a cash distribution of $0.35 per unit per quarter pro rated to cover the time period from the closing of the initial public offering through December 31, 2006. The distributable cash flow generated in the first quarter is approximately 1.3 times the amount of the cash distribution to unitholders.

"We are pleased with the results and operations of Universal Compression Partners," commented Mr. Snider, Universal Compression Partners' Chairman, President and Chief Executive Officer. "We are excited about growth opportunities due to favorable market conditions and the large pool of domestic contract compression customers and equipment that can be offered for sale from Universal Compression Holdings 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, and Gross Margin, as adjusted, 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, and Gross Margin, as adjusted, 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, 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.
