Western Gas Partners Announces Second-Quarter 2009 Results

Western Gas Partners, LP (NYSE: WES) today announced second-quarter 2009 financial and operating results.

Net income available to limited partners for the second quarter of 2009 totaled $17.8 million, or $0.32 per limited partner unit (diluted). The Partnership’s second-quarter Adjusted EBITDA⁽¹⁾ was $24.9 million and distributable cash flow⁽¹⁾ was $22.8 million, resulting in a coverage ratio of 1.30 times for the period.

"We reported strong performance during the second quarter, primarily as a result of stable throughput and continued progress on cost-reduction initiatives with respect to both operating expenses and capital expenditures,” said Western Gas Partners’ President and Chief Executive Officer Robert Gwin. "In addition, we continue to deliver upon our growth strategy, as evidenced by the recent closing of another acquisition from Anadarko Petroleum Corporation (NYSE: APC) and the recent increase in our quarterly distribution.”

Total throughput for the second quarter of 2009 averaged 1,060 MMcf/d, essentially flat compared to the prior quarter, and approximately 6 percent below the second quarter of 2008.

Capital expenditures totaled approximately $5.2 million during the second quarter of 2009. Of this amount, maintenance capital expenditures were approximately $4.5 million, or 18 percent of Adjusted EBITDA.

The Partnership previously declared a quarterly distribution of $0.31 per unit for the second quarter of 2009, payable on August 14, 2009 to unitholders of record at the close of business on July 31, 2009, representing an approximately 3-percent increase over the prior quarter.

Western Gas Partners believes that its expectations are based on reasonable assumptions. No assurance, however, can be given that such expectations will prove to have been correct.

Reconciliation of GAAP to Non-GAAP Measures

Below are reconciliations of Distributable Cash Flow and Adjusted EBITDA (non-GAAP) to Net Income (GAAP) as required under Regulation G of the Securities Exchange Act of 1934. Management believes that the presentation of Distributable Cash Flow and Adjusted EBITDA provides information useful in assessing the Partnership’s financial condition and results of operations and that Distributable Cash Flow and Adjusted EBITDA are widely accepted financial indicators of a company’s ability to incur and service debt, fund capital expenditures and make distributions. Distributable Cash Flow and Adjusted EBITDA, as defined by the Partnership, may not be comparable to similarly titled measures used by other companies. Therefore, the Partnership’s consolidated Distributable Cash Flow and Adjusted EBITDA should be considered in conjunction with net income and other performance measures, such as operating income or cash flow from operating activities.

Distributable Cash Flow

The Partnership defines Distributable Cash Flow as Adjusted EBITDA, plus interest income, less net cash paid for interest expense, maintenance capital expenditures and income taxes.

Reconciliation of GAAP to Non-GAAP Measures, continued

Adjusted EBITDA

The Partnership defines Adjusted EBITDA as net income (loss), plus distributions from equity investee, non-cash share-based compensation expense, interest expense, income tax expense and depreciation and impairment, less income from equity investment, interest income, income tax benefit and other income.
