Third Quarter 2010 Results

HOUSTON, November 4, 2010 – Exterran Holdings, Inc. (NYSE: EXH) and Exterran Partners, L.P. (NASDAQ: EXLP) today reported financial results for the third quarter 2010.

Exterran Holdings, Inc. Financial Results

Exterran Holdings reported a net loss attributable to Exterran stockholders for the third quarter 2010 of $18.0 million, or $0.29 per diluted share, compared to net income attributable to Exterran stockholders for the second quarter 2010 of $17.5 million, or $0.28 per diluted share, and net income attributable to Exterran stockholders for the third quarter 2009 of $18.2 million, or $0.30 per diluted share.

Net loss from continuing operations attributable to Exterran stockholders for the third quarter 2010 was $15.2 million, or $0.25 per diluted share, excluding after-tax impairment charges of $1.4 million.  Net loss from continuing operations for the second quarter 2010 attributable to Exterran stockholders, excluding charges, was $20.6 million, or $0.33 per diluted share, and net income from continuing operations for the third quarter 2009 attributable to Exterran stockholders, excluding charges, was $24.8 million, or $0.38 per diluted share.

Revenue was $625.6 million for the third quarter 2010, compared to $643.8 million for the second quarter 2010 and $679.7 million for the third quarter 2009.  EBITDA, as adjusted (as defined below), was $109.7 million for the third quarter 2010, compared to $117.8 million for the second quarter 2010 and $161.1 million for the third quarter 2009.

Ernie L. Danner, Exterran Holdings’ President and Chief Executive Officer, said, “Third quarter highlights include increased operating horsepower levels in our North America contract operations business and improved operating results in our fabrication segment. As expected, operating results of our international contract operations business declined sequentially primarily due to the previously announced early termination of a project in Brazil in the second quarter 2010.

New business development activity was mixed during the quarter, as an improved level of compression and production and processing fabrication bookings in North America contrasted with a muted overall level of contract awards in international markets.  With a leading market position in our compression and production and processing business lines, we believe that we are well-positioned to capture growth opportunities particularly related to North America shale plays and international energy infrastructure development in 2011 and beyond.

Our capital position was enhanced during the quarter as Exterran Holdings sold 5.3 million common units representing limited partner interests in Exterran Partners in September 2010 for net proceeds to Exterran Holdings of approximately $109 million.  We expect net capital expenditures in 2010 of $200 million to $220 million, as compared to previous guidance of $225 million to $250 million.”

Exterran Partners, L.P. Financial Results

Exterran Partners reported revenue of $62.7 million for the third quarter 2010, compared to $53.8 million for the second quarter 2010 and $41.3 million for the third quarter 2009.  Net income was $0.1 million for the third quarter 2010, or a loss of $0.01 per diluted limited partner unit, compared to a net loss of $1.3 million, or $0.07 per diluted limited partner unit, for the second quarter 2010, and net income of $2.0 million, or $0.09 per diluted limited partner unit, for the third quarter 2009.

Exterran Partners’ EBITDA, as further adjusted (as defined below), totaled $28.0 million for the third quarter 2010, compared to $22.9 million for the second quarter 2010 and $18.4 million for the third quarter 2009.  Distributable cash flow (as defined below) totaled $19.3 million for the third quarter 2010, compared to $12.8 million for the second quarter 2010 and $10.6 million for the third quarter 2009.

“Our distributable cash flow and credit profile were enhanced by the acquisition of assets representing approximately 255,000 horsepower of compression capacity from Exterran Holdings in August 2010.  Further, Exterran Partners increased operating horsepower during the quarter as a result of improved customer activity,” commented Mr. Danner, Chairman, President and Chief Executive Officer of Exterran Partners’ managing general partner.  “We are pleased with Exterran Holdings’ sale of Exterran Partners common units in September 2010, which has led to increased daily trading volumes and enhanced overall liquidity of the market for Exterran Partners units.  Looking ahead, we remain committed to growing the partnership through acquisitions and organic growth, and increasing distribut ions to unitholders over time.”

On October 29, 2010, Exterran Partners announced a third quarter 2010 cash distribution of $0.4675 per limited partner unit, or $1.87 per limited partner unit on an annualized basis.   This distribution will be paid on November 12, 2010 to unitholders of record as of the close of business on November 9, 2010.

The distribution to be paid in November 2010 is $0.005 higher than the second quarter 2010 and third quarter 2009 distributions of $0.4625 per limited partner unit.

(1) Management believes disclosure of EBITDA, as further adjusted, diluted earnings (loss) per limited partner unit, excluding charge, and Gross Margin, as adjusted, non-GAAP measures, provides 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, diluted earnings (loss) per limited partner unit, excluding charge, 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.
