FOR IMMEDIATE RELEASE

Plains All American Pipeline, L.P. Reports

Third-Quarter 2012 Results

(Houston — November 5, 2012) Plains All American Pipeline, L.P. (NYSE: PAA) today reported net income attributable to Plains for the third quarter of 2012 of $165 million, or $0.27 per diluted limited partner unit.  These results include the impact of non-cash asset impairment charges totaling $125 million, primarily related to the Partnership’s determination not to proceed with the development of the Pier 400 terminal project in California.  Such results compare to net income attributable to Plains of $281 million, or $0.74 per diluted limited partner unit for the third quarter of 2011.  The Partnership reported earnings before interest, taxes, depreciation and amortization (“EBITDA”) of $470 million for the third quarter of 2012, compared to reported EBITDA of $421 million for the third quarter of 2011.

The Partnership’s reported results include the impact of items that affect comparability between reporting periods.   The impact of items impacting comparability are excluded from adjusted results, as detailed in the table below. Accordingly, the Partnership’s third-quarter 2012 adjusted net income attributable to Plains, adjusted net income per diluted limited partner unit and adjusted EBITDA were $322 million, $0.73 and $502 million, respectively.  The comparable amounts for the third quarter of 2011 were $274 million, $0.71 and $414 million. (See the section of this release entitled “Non-GAAP Financial Measures” and the attached tables for discussion of EBITDA and other non-GAAP financial measures and their reconciliation to the most directly comparable GAAP measures.)

“Continuing a multi-quarter trend, PAA delivered strong adjusted results for the third quarter of 2012,” said Greg L. Armstrong, Chairman and CEO of Plains All American.  “The environment for crude oil production growth in North America remains very favorable and we continue to experience strong demand for our assets and services. As a result, we have increased our midpoint guidance for adjusted EBITDA to slightly over $2 billion for the full year of 2012, representing a 7% increase over our previous guidance midpoint for 2012.

“We are also expanding our asset base to meet the growing needs of our customers.  Thus far in 2012, we have invested approximately $2.5 billion in organic growth projects and acquisitions and expect to incrementally invest over $1 billion in organic growth projects through the end of 2013.  These investments provide meaningful visibility for increased baseline cash flow and distributions to unitholders.”

Armstrong added, “In addition to delivering solid operating and financial results, we ended the quarter with a strong balance sheet, credit metrics favorable to our targets and approximately $2.4 billion of committed liquidity.  As a result, we are well positioned to finance our growth while maintaining a solid financial position.”

The following table summarizes selected items that the Partnership believes impact comparability of financial results between reporting periods (amounts in millions, except per unit amounts):

(1)             Per-unit amounts are presented as adjusted for the two-for-one unit split effected on October 1, 2012.

(2)             Certain of our non-GAAP financial measures may not be impacted by each of the selected items impacting comparability.

(3)             Includes mark-to-market gains and losses resulting from derivative instruments that are related to underlying activities in future periods or the reversal of mark-to-market gains and losses from the prior period net of inventory valuation adjustments.

(4)    Asset impairments are reflected in “Depreciation and amortization” on our Consolidated Statements of Operations and do not impact the comparability of EBITDA.

(5)             Equity compensation expense for the three and nine months ended September 30, 2012 and 2011 excludes the portion of equity compensation expense represented by grants under our Long-term Incentive Plans (“LTIPs”) that, pursuant to the terms of the grant, will be settled in cash only and have no impact on diluted units.

Adjusted Transportation segment profit in the third quarter of 2012 increased by 23% over comparable 2011 results.  This increase was primarily driven by higher revenues from acquisitions completed late in 2011 and early in 2012, organic growth capacity expansions, increased pipeline volumes and higher average pipeline tariffs.  These increases in revenue were partially offset by higher operating and general and administrative expenses, commensurate with the growth of the business.

Adjusted Facilities segment profit in the third quarter of 2012 increased 48% over comparable 2011 results.  This increased profitability is primarily related to capacity additions from the BP NGL acquisition and recently completed organic growth projects.

Adjusted Supply and Logistics segment profit in the third quarter of 2012 increased 5% over comparable 2011 results.  This increase was primarily due to favorable crude oil market conditions and increased crude oil lease gathering and NGL sales volumes.

The Partnership’s basic weighted average units outstanding for the third quarter of 2012 was 329 million units (331 million diluted) as compared to 299 million units (300 million diluted) in last year’s third quarter.  At the end of the third quarter, the Partnership had approximately 331.6 million units outstanding. These amounts have been adjusted for the two-for-one unit split effected on October 1, 2012.  The Partnership had long-term debt of approximately $5.8 billion and a long-term debt-to-total capitalization ratio of 46% at the end of the third quarter.

The Partnership has declared a quarterly distribution of $0.5425 per unit ($2.17 per unit on an annualized basis) payable November 14, 2012, on its outstanding limited partner units.  This distribution represents an increase of approximately 9.0% over the quarterly distribution paid in November 2011 and an increase of approximately 1.9% over the quarterly distribution paid in August 2012.

The Partnership will hold a conference call at 9:00 AM (Central) on November 6, 2012 (see details below).  Prior to this conference call, the Partnership will furnish a current report on Form 8-K, which will include material in this press release and financial and operational guidance for the fourth-quarter and full-year 2012 as well as preliminary financial guidance for 2013.  A copy of the Form 8-K will be available on the Partnership’s website at www.paalp.com.

Non-GAAP Financial Measures

To supplement our financial information presented in accordance with GAAP, management uses additional measures that are known as “non-GAAP financial measures” in its evaluation of past performance and prospects for the future. These measures include adjusted EBITDA and implied distributable cash flow (“DCF”).  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.” These additional financial measures are reconciled from the most directly comparable measures as reported in accordance with GAAP, and should be viewed in addition to, and not in lieu of, our consolidated financial statements and footnotes.

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. A full analysis of 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 Quarterly Report on Form 10-Q.
