“PAA ended the year on another strong note, delivering adjusted EBITDA that exceeded the midpoint of our fourth-quarter guidance by $50 million and the mid-point of our 2013 beginning-of-the-year guidance by over $265 million,” stated Greg L. Armstrong, Chairman and CEO of Plains All American Pipeline.  “These results were underpinned by solid performance in our fee-based Facilities segment and above baseline performance in our Supply and Logistics segment.”

“PAA’s 2013 results and our 2014 guidance for our fee-based Transportation and Facilities segments continue to reflect the benefits of our ongoing expansion capital program.  Aggregate adjusted segment profit from our Transportation and Facilities segments increased 12% in 2013 over 2012 results, and the midpoint of our guidance range anticipates a year-to-year increase of approximately 15% in 2014,” said Armstrong. “Guidance for our Supply and Logistics segment incorporates a return to baseline-type performance; however, as in prior years, the partnership remains well positioned to outperform guidance if market conditions remain favorable.”

“We have targeted to grow PAA’s distributions per unit by approximately 10% in 2014, while continuing to maintain solid distribution coverage.” Armstrong stated that the partnership’s 2014 expansion capital program increased to $1.7 billion, which reflects a $300 million increase from PAA’s preliminary targeted range. Armstrong also noted that PAA is well positioned financially to both execute its expansion capital program as well as capitalize on potential acquisition opportunities.

The following table summarizes selected PAA financial information by segment for the fourth quarter and full year of 2013:

Fourth-quarter 2013 Transportation adjusted segment profit increased 8% versus comparable 2012 results. This increase was primarily driven by the benefit of higher crude oil pipeline volumes   associated with recently completed organic growth projects, partially offset by the sale of our refined products pipelines and lower volumes on our Canadian crude oil pipelines due to the impact of rail and proration on downstream pipelines.

Fourth-quarter 2013 Facilities adjusted segment profit increased 20% over comparable 2012 results, primarily due to increased crude oil rail activities.

Fourth-quarter 2013 Supply and Logistics adjusted segment profit exceeded our guidance, but decreased by approximately 22% relative to comparable 2012 results. This decrease was primarily related to less favorable crude oil market conditions during the fourth quarter of 2013, particularly narrower crude oil differentials in the Permian Basin and Gulf Coast regions, partially offset by stronger net margins in the NGL business.

Plains GP Holdings

PAGP’s sole assets are its ownership interest in PAA’s general partner and incentive distribution rights.  As the control entity of PAA, PAGP consolidates PAA’s results into its financial statements, which are reflected more fully in the condensed consolidating balance sheet and income statement included at the end of this release.  Information regarding PAGP’s distributions is reflected below:

(1) Distribution per share declared based on prorated distribution received by PAGP from PAA’s general partner, Plains AAP, L.P. (“AAP”), for the partial quarter of ownership following the closing of PAGP’s initial public offering (“IPO”).

(2) Reflects a full fourth quarter 2013 distribution per Class A share (before proration), assuming PAGP’s current ownership interest in AAP for the full fourth quarter of 2013.

Non-GAAP Financial Measures and Selected Items Impacting Comparability

To supplement our financial information presented in accordance with GAAP, management uses additional measures that are known as “non-GAAP financial measures” (such as adjusted EBITDA and implied 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 performance and results of operations because these measures, when used in conjunction with related GAAP financial measures, (i) provide additional information about our core operating performance 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. These measures may exclude, for example, (i) charges for obligations that are expected to be settled with the issuance of equity instruments, (ii) the mark-to-market of derivative instruments that are related to underlying activities in another period (or the reversal of such adjustments from a prior period), (iii) items that are not indicative of our core operating results and business outlook and/or (iv) other items that we believe should be excluded in understanding our core operating performance. We have defined all such items as “selected items impacting comparability.”  We consider an understanding of these selected items impacting comparability to be material to the 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, exchange rates, mechanical interruptions, acquisitions and numerous other factors. These types of variations are not separately identified in this release, but will be discussed, as applicable, in management’s discussion and analysis of operating results in our Annual Report on Form 10-K.

Adjusted EBITDA and other non-GAAP financial measures are reconciled to the most comparable GAAP measures 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, PAA maintains on its website (www.plainsallamerican.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 “Plains All American Pipeline, L.P.” under the “Investor Relations” link on the home page, select the “Guidance & Non-GAAP Reconciliations” link and navigate to the “Non-GAAP Reconciliations” tab.
