PAA Natural Gas Storage, L.P. : PAA Natural Gas Storage Reports Second-Quarter 2013 Results

PAA Natural Gas Storage, L.P. (NYSE: PNG) reported second-quarter 2013 results as summarized below:

"PNG reported second-quarter adjusted EBITDA that exceeded the high end of our guidance range," said Dean Liollio, President of PAA Natural Gas Storage. "Our results were underpinned by our fee-based firm storage contracts, with over performance generated by merchant storage revenues previously expected to be realized later in the year and higher than forecasted oil revenues associated with liquids removal activities at our Bluewater facility."

"Although market conditions for natural gas storage have weakened considerably over the last few months, we are pleased with the performance of our assets and our team through the first half of 2013 as well as our positioning for the remainder of the year. Our organic growth projects remain on time and on budget, and we continue to execute our disciplined business strategy while maintaining a solid balance sheet and liquidity."

The following table summarizes selected financial data for the second quarter and first half of 2013:

Second-quarter 2013 adjusted EBITDA increased 3.1% over comparable 2012 results. This increase was primarily related to the realization of merchant storage revenues previously expected in the later portion of this year and higher than forecasted oil revenues associated with liquids removal activities at Bluewater, partially offset by higher field operating costs and G&A expenses.

The Partnership's common units and Series A subordinated units outstanding as of June 30, 2013 totaled 72.6 million. An additional 13.5 million Series B subordinated units (which are not currently entitled to receive distributions) are outstanding and do not convert to Series A subordinated units unless certain performance conditions are met.

Non-GAAP Financial Measures, Segment Financial Measures and Selected Items Impacting Comparability

To supplement our financial information presented in accordance with GAAP, management uses adjusted EBITDA and distributable cash flow in its evaluation of past performance and prospects for the future. Management believes that the presentation of such additional financial measures provides useful information to investors regarding our financial condition and results of operations because these measures, when used in conjunction with related GAAP financial measures, (i) provide additional information about our core operations and ability to generate and distribute cash flow, (ii) provide investors with the financial analytical framework upon which management bases financial, operational, compensation and planning decisions and (iii) present measurements that investors, rating agencies and debt holders have indicated are useful in assessing us and our results of operations. Adjusted EBITDA and/or distributable cash flow may exclude, for example, the impact of unique and infrequent items, items outside of management's control and/or items that are not indicative of our core operating results and business outlook, which we define as "selected items impacting comparability." We consider an understanding of these selected items impacting comparability to be material to our evaluation of our operating results and prospects.

Although we present selected items that we consider in evaluating our performance, you should also be aware that the items presented do not represent all items that affect comparability between the periods presented. Variations in our operating results are also caused by changes in volumes, prices, mechanical interruptions, acquisitions and numerous other factors. These types of variations are not fully identified and discussed in this release, but will be discussed, as applicable, in management's discussion and analysis of operating results in our Quarterly Report on Form 10-Q.

Adjusted EBITDA and other non-GAAP financial measures are reconciled to net income, the most comparable GAAP measure, for the periods presented in the tables attached to this release, and should be viewed in addition to, and not in lieu of, our consolidated financial statements and notes thereto. In addition, the Partnership maintains on its website (www.pnglp.com) a reconciliation of adjusted EBITDA and certain commonly used non-GAAP financial information to the most comparable GAAP measures. To access the information, investors should click on the "Investor Relations" link on the Partnership's home page and then the "Non-GAAP Reconciliations" link on the Investor Relations page.
