Item 2.02 and Item 7.01. Results of Operations and Financial Condition; Regulation FD Disclosure

Plains All American Pipeline, L.P. (the “Partnership”) today issued a press release reporting its fourth-quarter and annual 2011 results. We are furnishing the press release, attached as Exhibit 99.1, pursuant to Item 2.02 and Item 7.01 of Form 8-K.  Pursuant to Item 7.01, we are providing first-quarter and full year 2012 detailed guidance for financial performance.  In accordance with General Instruction B.2. of Form 8-K, the information presented herein under Item 2.02 and Item 7.01 shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), nor shall it be deemed incorporated by reference in any filing under the Exchange Act or Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing.

Disclosure of First Quarter and Full Year 2012 Guidance

To supplement our financial information presented in accordance with GAAP, management uses additional measures known as “non-GAAP financial measures” 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.  EBIT and EBITDA (each as defined below in Note 1 to the “Operating and Financial Guidance” table) are non-GAAP financial measures. Net income represents one of the two most directly comparable GAAP measures to EBIT and EBITDA. In Note 10 below, we reconcile net income to EBIT and EBITDA for the 2012 guidance periods presented. Cash flow from operating activities is the other most comparable GAAP measure. We do not, however, reconcile cash flows from operating activities to EBIT and EBITDA, because such reconciliations are impractical for a forecasted period. We encourage you to visit our website at www.paalp.com (in particular the section entitled “Non-GAAP Reconciliations”), which presents a historical reconciliation of EBIT and EBITDA as well as certain other commonly used non-GAAP financial measures. In addition, we have highlighted the impact of (i) equity compensation expense and (ii) acquisition related expenses.  Due to the nature of the selected items, certain of the selected items impacting comparability may impact certain non-GAAP financial measures but not impact other non-GAAP financial measures.

We based our guidance for the three-month period ending March 31, 2012 and twelve-month period ending December 31, 2012 on assumptions and estimates that we believe are reasonable, given our assessment of historical trends (modified for changes in market conditions), business cycles and other reasonably available information. Projections covering multi-quarter periods contemplate inter-period changes in future performance resulting from new expansion projects, seasonal operational changes (such as NGL or LPG sales) and acquisition synergies. Our assumptions and future performance, however, are both subject to a wide range of business risks and uncertainties, so no assurance can be provided that actual performance will fall within the guidance ranges. Please refer to information under the caption “Forward-Looking Statements and Associated Risks” below. These risks and uncertainties, as well as other unforeseeable risks and uncertainties, could cause our actual results to differ materially from those in the following table. The operating and financial guidance provided below is given as of the date hereof, based on information known to us as of February 7, 2012. We undertake no obligation to publicly update or revise any forward-looking statements.

On December 1, 2011 PAA announced it had signed a definitive agreement to acquire BP’s Canadian NGL and LPG business (“BP NGL acquisition”).  For purposes of preparing this guidance we have assumed that the acquisition closes on April 1, 2012 and thus we have included no benefit from the acquisition in our guidance for the three months ending March 31, 2012.  The projections for the acquisition included in this document, including the segment and volume specific detail, are preliminary and may change or be refined after the acquisition closes.

Operating and Financial Guidance

(in millions, except per unit data)

Notes and Significant Assumptions:

1. Definitions.

2.               Operating Segments. We manage our operations through three operating segments: (i) Transportation, (ii) Facilities and (iii) Supply and Logistics. The following is a brief explanation of the operating activities for each segment as well as key metrics.

a.               Transportation. Our transportation segment operations generally consist of fee-based activities associated with transporting crude oil and refined products on pipelines, gathering systems, trucks and barges. We generate revenue through a combination of tariffs, third-party leases of pipeline capacity and transportation fees. Our transportation segment also includes our equity earnings from our investments in the Butte, Frontier and White Cliffs pipeline systems and Settoon Towing, in which we own non-controlling interests.

Pipeline volume estimates are based on historical trends, anticipated future operating performance and assumed completion of internal growth projects. Actual volumes will be influenced by maintenance schedules at refineries, production trends, weather and other natural occurrences including hurricanes, changes in the quantity of inventory held in tanks, and other external factors beyond our control. We forecast adjusted segment profit using the volume assumptions in the table below, priced at forecasted tariff rates, less estimated field operating costs and G&A expenses. Field operating costs do not include depreciation. Actual segment profit could vary materially depending on the level and mix of volumes transported or expenses incurred during the period.

The following table summarizes our total pipeline volumes and highlights major systems that are significant either in total volumes transported or in contribution to total transportation segment profit.

4

(1)           The aggregate of multiple systems in their respective areas.

(2)           Twelve months ending December 31, 2012 reflect the preliminary volume forecast for the BP NGL acquisition with an assumed closing date of April 1, 2012.  Such forecast is preliminary and subject to change as we finalize the applicable segment disclosures and volume/profit drivers.

(3)           Mid-point of guidance.

b.              Facilities. Our facilities segment operations generally consist of fee-based activities associated with providing storage, terminalling and throughput services for crude oil, refined products, NGL, LPG and natural gas, as well as NGL/LPG fractionation and isomerization services. We generate revenue through a combination of month-to-month and multi-year leases and processing arrangements.

Adjusted segment profit is forecasted using the volume assumptions in the table below, priced at forecasted rates, less estimated field operating costs and G&A expenses. Field operating costs do not include depreciation.

(1)          Twelve months ending December 31, 2012 reflect the preliminary volume forecast for the BP NGL acquisition with an assumed closing date of April 1, 2012.  Such forecast is preliminary and subject to change as we finalize the applicable segment disclosures and volume/profit drivers.

(2)          Calculated as the sum of: (i) crude oil, refined products and NGL/LPG storage capacity; (ii) natural gas storage capacity divided by the gas to crude Btu equivalent ratio of 6 mcf of gas to 1 barrel of crude oil; and (iii) NGL/LPG processing volumes (based on estimated utilized capacity), multiplied by the number of days in the period and divided by the number of months in the period.

(3)          Mid-point of guidance.

5

c.               Supply and Logistics. Our supply and logistics segment operations generally consist of the following activities:

·                  the purchase of crude oil at the wellhead, the bulk purchase of crude oil at pipeline and terminal facilities, and the purchase of cargos at their load port and various other locations in transit;

·                  the storage of inventory during contango market conditions and the seasonal storage of NGL/LPG;

·                  the purchase of refined products and NGL/LPG from producers, refiners and other marketers;

·                  the resale or exchange of crude oil, refined products and NGL/LPG at various points along the distribution chain to refiners or other resellers to maximize profits; and

·                  the transportation of crude oil, refined products and NGL/LPG on trucks, barges, railcars, pipelines and ocean-going vessels to our terminals and third-party terminals.

We characterize a substantial portion of the profit generated by our supply and logistics segment as fee equivalent. This portion of the segment profit is generated by the purchase and resale of crude oil production at the wellhead on an index-related basis, which results in us generating a gross margin for such activities.  This gross margin is reduced by the transportation, facilities and other logistical costs associated with delivering the crude oil to market as well as any operating and general and administrative expenses.  The level of profit associated with a portion of the other activities we conduct in the supply and logistics segment is influenced by overall market structure and the degree of volatility in the crude oil market, as well as variable operating expenses. Forecasted operating results for the three-month period ending March 31, 2012 reflect the current market structure and the seasonal, weather-related variations in LPG sales.  Variations in weather, market structure or volatility could cause actual results to differ materially from forecasted results.

We forecast adjusted segment profit using the volume assumptions stated below, as well as estimates of unit margins, field operating costs, G&A expenses and carrying costs for contango inventory, based on current and anticipated market conditions. Actual volumes are influenced by temporary market-driven storage and withdrawal of oil, maintenance schedules at refineries, production declines, weather, and other external factors beyond our control. Field operating costs do not include depreciation. Realized unit margins for any given lease-gathered barrel could vary significantly based on a variety of factors including location, quality, and contract structure. Accordingly, the projected segment profit per barrel can vary significantly even if aggregate volumes are in line with the forecasted levels.

(1)           Twelve months ending December 31, 2012 reflect the preliminary volume forecast for the BP NGL acquisition with an assumed closing date of April 1, 2012.  Such forecast is preliminary and subject to change as we finalize the applicable segment disclosures and volume/profit drivers for the period.  Additionally, it is based on our preliminary forecast of 3rd party sales volumes as a significant portion of the supply from the BP NGL acquisition is anticipated to offset our 3rd party purchases for our existing (pre-acquisition) demand-based LPG business.

(2)           Mid-point of guidance.

3.               Depreciation and Amortization. We forecast depreciation and amortization based on our existing depreciable assets, forecasted capital expenditures and projected in-service dates. Depreciation may vary during any one period due to gains and losses on intermittent sales of assets, asset retirement obligations, asset impairments or foreign exchange rates.

6

4.               Capital Expenditures and Acquisitions.  As stated above, this guidance includes the effect of the pending BP NGL acquisition.  Although acquisitions constitute a key element of our growth strategy, the forecasted results and associated estimates do not include any forecasts for acquisitions that we may commit to after the date hereof. We forecast capital expenditures during calendar 2012 to be approximately $850 million for expansion projects with an additional $130 to $150 million for maintenance capital projects. Such amounts include post-closing capital expenditures associated with the BP NGL acquisition, but do not include acquisition costs of such transaction. Following are some of the more notable projects and forecasted expenditures for the year ending December 31, 2012:

5.               Capital Structure. This guidance is based on our capital structure as of December 31, 2011 and assumes that we access the debt and equity capital markets during the second half of the year to provide long-term funding for the BP NGL acquisition and our expansion capital program.

6.               Interest Expense. Debt balances are projected based on estimated cash flows, estimated distribution rates, estimated capital expenditures for maintenance and expansion projects, funding requirements for the BP NGL acquisition, expected timing of collections and payments and forecasted levels of inventory and other working capital sources and uses. Interest rate assumptions for variable-rate debt are based on the current forward LIBOR curve.

Included in interest expense are commitment fees, amortization of long-term debt discounts or premiums, deferred amounts associated with terminated interest-rate hedges and interest on short-term debt for non-contango inventory (primarily hedged LPG inventory and New York Mercantile Exchange and IntercontinentalExchange margin deposits). Interest expense is net of amounts capitalized for major expansion capital projects and does not include interest on borrowings for inventory stored in a contango market. We treat interest on contango-related borrowings as carrying costs of crude oil and include it in purchases and related costs.

7.              Income Taxes. We expect Canadian income tax expense to be approximately $10 million and $50 million for the three-month and twelve-month periods ending March 31, 2012 and December 31, 2012, respectively, of which approximately $10 million and $55 million, respectively, is classified as current.  For the twelve-month period ending December 31, 2012 we expect to have a deferred tax benefit of $5 million.  All or part of the income tax expense of $50 million may result in a tax credit to our equity holders.

7

8.               Reconciliation of Adjusted EBITDA to Implied DCF. The following table reconciles the mid-point of adjusted EBITDA to implied distributable cash flow for the three-month period ending March 31, 2012 and the twelve-month period ending December 31, 2012.

9.               Equity Compensation Plans. The majority of grants outstanding under our various equity compensation plans contain vesting criteria that are based on a combination of performance benchmarks and service periods. The grants will vest in various percentages, typically on the later to occur of specified vesting dates and the dates on which minimum distribution levels are reached. Among the various grants outstanding as of February 7, 2012, estimated vesting dates range from February 2012 to May 2019 and annualized distribution levels range from $3.75 to $4.80. For some awards, a percentage of any units remaining unvested as of a date certain will vest on such date and all others will be forfeited.

On January 10, 2012, we declared an annualized distribution of $4.10 payable on February 14, 2012 to our unitholders of record as of February 3, 2012. We have made the assessment that a $4.35 distribution level is probable of occurring, and accordingly, for grants that vest at annualized distribution levels of $4.35 or less, guidance includes an accrual over the applicable service period at an assumed market price of $73.00 per unit as well as an accrual associated with awards that will vest on a date certain. The actual amount of equity compensation expense amortization in any given period will be directly influenced by (i) our unit price at the end of each reporting period, (ii) our unit price on the vesting date (iii) the probability assessment regarding distributions, and (iv) new equity compensation award grants. For example, a $3.00 change in the unit price assumption at March 31, 2012 would change the first-quarter equity compensation expense by approximately $4 million and the full-year equity compensation expense by approximately $12 million. Therefore, actual net income could differ materially from our projections.

10.         Reconciliation of Net Income to EBIT and EBITDA. The following table reconciles net income to EBIT and EBITDA for the three-month and twelve-month periods ending March 31, 2012 and December 31, 2012, respectively.

Exhibit 99.1

FOR IMMEDIATE RELEASE

Plains All American Pipeline, L.P. Reports

Fourth-Quarter and Full-Year 2011 Results

(Houston — February 8, 2012) Plains All American Pipeline, L.P. (NYSE: PAA) today reported net income attributable to Plains of $278 million, or $1.37 per diluted limited partner unit, for the fourth quarter of 2011 and net income attributable to Plains of $966 million, or $4.88 per diluted limited partner unit, for the full year 2011.  Net income attributable to Plains for the fourth quarter of 2010 was $142 million, or $0.67 per diluted limited partner unit, and net income attributable to Plains for the full year 2010 was $505 million, or $2.40 per diluted limited partner unit.  The Partnership reported earnings before interest, taxes, depreciation and amortization (“EBITDA”) of $426 million and $1.54 billion for the respective fourth-quarter and full-year 2011 periods compared to reported EBITDA of $277 million and $1.02 billion, for the comparable 2010 periods.

“PAA delivered record level performance for the fourth quarter and full year of 2011 and meaningfully exceeded our public guidance ranges,” said Greg L. Armstrong, Chairman and CEO of Plains All American. “These results are a testament to the strength of PAA’s business model and strategic asset base and the outstanding execution by PAA’s employees during a period of strong fundamentals and favorable market conditions.”

“Looking forward, PAA is well positioned to continue to deliver attractive results. During 2011, we invested $1.9 billion in expansion capital and acquisitions and we plan to invest over $2.5 billion in 2012 through our $850 million expansion capital program and our pending $1.7 billion acquisition of BP’s Canadian NGL business.  PAA is also well positioned to finance this growth while maintaining a solid capital structure and a high level of liquidity.  As a result of our proactive financing activities and cash generated in excess of our distributions, PAA ended the year with a strong balance sheet, over $3.5 billion of committed liquidity and favorably positioned with respect to our targeted credit profile.”

“Based on this positioning and strong industry fundamentals, we are targeting to increase our limited partner distributions by 8% to 9% during 2012, while maintaining attractive distribution coverage levels.”

The Partnership’s reported results include the impact of items that affect comparability between reporting periods.  These items are excluded from adjusted results, as detailed in the table below.  Accordingly, the Partnership’s fourth-quarter 2011 adjusted net income attributable to Plains, adjusted net income per diluted limited partner unit and adjusted EBITDA were $322 million, $1.65 and $471 million, respectively, as compared to fourth-quarter 2010 respective results of $187 million, $0.99 and $322 million.

The Partnership’s adjusted net income attributable to Plains, adjusted net income per diluted limited partner unit and adjusted EBITDA for the full year 2011 were $1.02 billion, $5.24 and $1.60 billion, respectively, as compared to the full-year 2010 respective results of $594 million, $3.03 and $1.11 billion. (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 reconciliations of such measures to the comparable GAAP measures.)

Page 2

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

(2) Equity compensation expense for both the three and twelve months ended December 31, 2011 and 2010 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.

(3) Includes other immaterial selected items impacting comparability, as well as the noncontrolling interests’ portion of selected items.

Page 3

The following tables present certain selected financial information by segment for the fourth-quarter and full-year 2011 and 2010 reporting periods (amounts in millions):

(1) Includes intersegment amounts.

(2) Segment general and administrative expenses (G&A) reflect direct costs attributable to each segment and an allocation of other expenses to the segments based on the business activities that existed at that time.  The proportional allocations by segment require judgment by management and will continue to be based on the business activities that exist during each period. Includes acquisition-related expenses for the 2011 periods.

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

Adjusted segment profit for the Transportation segment for the fourth quarter and full year 2011 increased by approximately 16% and 8%, respectively, over comparable 2010 results.  Increases for both periods were primarily driven by higher pipeline tariffs and volumes, partially offset by higher operating expenses.  Full-year 2011 results include a $31 million negative impact associated with the Rainbow pipeline incident that occurred during the second quarter.

Adjusted segment profit for the Facilities segment for the fourth quarter and full year 2011 increased by approximately 43% and 34%, respectively, over comparable 2010 results primarily due to the Southern Pines gas storage facility acquisition (closed in February 2011) and capacity increases from organic growth capital projects.

Adjusted segment profit for the Supply and Logistics segment for the fourth quarter and full year 2011 increased by approximately 83% and 121%, respectively, over comparable 2010 results primarily due to increased crude oil lease gathering volumes and margins related to high levels of drilling activity in areas that we service, the acquisition of Nexen’s Bakken crude oil business (closed in December 2010) and favorable crude oil market conditions.

Page 4

The Partnership’s basic weighted average units outstanding for the fourth quarter 2011 totaled 152 million (154 million diluted) as compared to 138 million (139 million diluted) in last year’s fourth quarter. On December 31, 2011, the Partnership had approximately 155.4 million units outstanding, long-term debt of approximately $4.5 billion and a long-term debt-to-total capitalization ratio of 43%.

The Partnership has declared a quarterly distribution of $1.025 per unit ($4.10 per unit on an annualized basis) payable February 14, 2012, on its outstanding limited partner units.  This distribution represents an increase of approximately 7.0% over the quarterly distribution paid in February 2011 and an increase of approximately 3.0% over the quarterly distribution paid in November 2011.

The Partnership will hold a conference call at 11:00 AM (Eastern) on February 9, 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 first quarter and full year 2012.  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 Annual Report on Form 10-K.

Conference Call

The Partnership will host a conference call at 11:00 AM (Eastern) on Thursday, February 9, 2012 to discuss the following items:

1.                           The Partnership’s fourth-quarter and full-year 2011 performance;

2.                           The status of major expansion projects;

3.                           Capitalization and liquidity;

4.                           Financial and operating guidance for the first quarter and full year 2012; and

5.                           The Partnership’s outlook for the future.
