See the section of this release entitled “Non-GAAP Financial Measures and Selected Items Impacting Comparability” and the tables attached hereto for information regarding certain selected items that PAA believes impact comparability of financial results between reporting periods, as well as for information regarding non-GAAP financial measures (such as adjusted EBITDA) and their reconciliation to the most directly comparable measures as reported in accordance with GAAP.


⁽²⁾	Prior period amounts have been recast to conform to certain changes made in the fourth quarter of 2016.

“Our first quarter results reflect in-line performance from our fee-based Transportation and Facilities segments as well as our margin-based crude oil marketing activities, but were adversely impacted by weaker than anticipated performance from our NGL marketing activities, which are included in our Supply and Logistics segment,” said Greg Armstrong, Chairman and CEO. “NGL margins were negatively impacted by warmer weather and tighter differentials between Canada and our US demand markets among other factors. To address these issues in future periods, we are modifying the way we manage our inventory and implementing contractual provisions that will reduce earnings volatility and the quantity of seasonal NGL inventory we store, in exchange for partially limiting our upside potential.

“In February, we shared our view that the first six to nine months of the current year would prove challenging but that we expected to see strong improvement toward the end of 2017 as several multi-year capital projects are completed and volume growth in the Permian advances. Although our cautious outlook for the near term is proving accurate, we definitely like the way the industry is shaping up for the latter part of 2017 and beyond.

“Producer activity levels in almost every area are ahead of levels included in our outlook at the beginning of the year, especially with respect to the Permian Basin. Well productivity is increasing as new wells are coming in stronger than previously modeled. Our outlook continues to incorporate an increasing time lag between increased drilling activity and increased production volumes as producers shift to multi-well pad operations. Accordingly, we continue to expect our transportation volumes to ramp up in the second half of this year.

“Consistent with our outlook, we are seeing increased interest from potential shippers for pipeline space currently available on our existing assets as well as for incremental pipeline capacity at rates that provide us an attractive return. All of this reinforces our outlook and confidence in a back-end weighted improvement during 2017 in our fee based growth and that we remain on-course for a meaningful increase in year-over-year performance in 2018 and beyond.”

Segment adjusted EBITDA for the first quarter of 2017 is presented below:

Summary of Selected Financial Data by Segment ⁽¹⁾ (unaudited)

(in millions)



	Three Months Ended March 31, 2017									Three Months Ended March 31, 2016
	Transportation			Facilities			Supply and Logistics			Transportation		Facilities		Supply and Logistics
Segment adjusted EBITDA	$	273		$	188		$	51		$	281	$	167	$	184
Percentage change in segment adjusted EBITDA versus 2016 period	(3		)%	13		%	(72		)%


⁽¹⁾	During the fourth quarter of 2016, we modified our primary segment performance measure to segment adjusted EBITDA from segment profit and also modified our definition of adjusted EBITDA to exclude our proportionate share of depreciation and amortization expense associated with equity method investments. Prior period segment amounts have been recast to reflect these changes.

First-quarter 2017 Transportation segment adjusted EBITDA decreased by 3% versus comparable 2016 results. This decrease was primarily driven by the impact of non-core asset sales and other volume decreases in the Rocky Mountain region primarily associated with pipeline downtime. These decreases were partially offset by increases on certain of our Permian Basin pipelines due largely to increased Delaware Basin production impacting our Basin pipeline and contributions from our Alpha Crude Connector gathering system which we acquired in February 2017.

First-quarter 2017 Facilities segment adjusted EBITDA increased by 13% versus comparable 2016 results. This increase was primarily due to contributions from the Canadian NGL assets we acquired in August 2016, higher fees at certain of our NGL storage and fractionation facilities and contributions from ongoing expansion projects at our Fort Saskatchewan facility. These increases were partially offset by lower U.S. rail terminal activity, lower utilization of our West Coast terminals, and the impact of non-core asset sales.

First-quarter 2017 Supply and Logistics segment adjusted EBITDA decreased by 72% relative to comparable 2016 results. This decrease was primarily driven by lower results from our NGL activities due to the impact of competition and continued margin compression, and unusually warm weather, as well as margin compression from our crude oil gathering and marketing activities caused by continued intense competition.

See the section of this release entitled “Non-GAAP Financial Measures and Selected Items Impacting Comparability” and the Financial Data Reconciliations table attached hereto for information regarding non-GAAP financial measures. For the historical 2015 and 2016 periods, please visit our website at www.plainsallamerican.com (in particular the section under “Financial Information” entitled “Non-GAAP Reconciliations” within the “Investor Relations” tab), for a reconciliation to the most directly comparable measures as reported in accordance with GAAP. We do not provide a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures on a forward-looking basis as it is impractical to forecast certain items that we have defined as “Selected Items Impacting Comparability” without unreasonable effort, due to the uncertainty and inherent difficulty of predicting the occurrence and financial impact of and the periods in which such items may be recognized. Thus, a reconciliation of non-GAAP financial measures to the equivalent GAAP financial measures could result in disclosure that could be imprecise or potentially misleading.

Non-GAAP Financial Measures and Selected Items Impacting Comparability

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. The primary additional measures used by management are earnings before interest, taxes, depreciation and amortization (including our proportionate share of depreciation and amortization of unconsolidated entities) and adjusted for certain selected items impacting comparability (“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 to supplement related GAAP financial measures, (i) provide additional information about our core operating performance and ability to fund distributions to our unitholders through cash generated by our operations and (ii) provide investors with the same financial analytical framework upon which management bases financial, operational, compensation and planning/budgeting decisions. We also present these and additional non-GAAP financial measures, including adjusted net income attributable to PAA and basic and diluted adjusted net income per common unit, as they are measurements that investors, rating agencies and debt holders have indicated are useful in assessing us and our results of operations. These non-GAAP measures may exclude, for example, (i) charges for obligations that are expected to be settled with the issuance of equity instruments, (ii) gains or losses on derivative instruments that are related to underlying activities in another period (or the reversal of such adjustments from a prior period), the mark-to-market related to our Preferred Distribution Rate Reset Option, gains and losses on derivatives that are related to investing activities (such as the purchase of linefill) and inventory valuation adjustments, as applicable, (iii) long-term inventory costing adjustments, (iv) items that are not indicative of our core operating results and business outlook and/or (v) other items that we believe should be excluded in understanding our core operating performance. These measures may further be adjusted to include amounts related to deficiencies associated with minimum volume commitments whereby we have billed

the counterparties for their deficiency obligation and such amounts are recognized as deferred revenue in “Accounts payable and accrued liabilities” on our Condensed Consolidated Financial Statements. Such amounts are presented net of applicable amounts subsequently recognized into revenue. Furthermore, the calculation of these measures contemplates tax effects as a separate reconciling item, where applicable. We have defined all such items as “selected items impacting comparability.” Due to the nature of the selected items, certain selected items impacting comparability may impact certain non-GAAP financial measures, referred to as adjusted results, but not impact other non-GAAP financial measures. We do not necessarily consider all of our selected items impacting comparability to be non-recurring, infrequent or unusual, but we believe that an understanding of these selected items impacting comparability is material to the evaluation of our operating results and prospects.

Although we present selected items impacting comparability that management considers 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, expansion projects 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 Quarterly Report on Form 10-Q.

Our definition and calculation of certain non-GAAP financial measures may not be comparable to similarly-titled measures of other companies. Adjusted EBITDA, Implied DCF and other non-GAAP financial performance measures are reconciled to Net Income (the most directly comparable measure as reported in accordance with GAAP) for the historical periods presented in the tables attached to this release, and should be viewed in addition to, and not in lieu of, our Condensed Consolidated Financial Statements and notes thereto. In addition, we encourage you to visit our website at www.plainsallamerican.com (in particular the section under “Financial Information” entitled “Non-GAAP Reconciliations” within the Investor Relations tab), which presents a reconciliation of our commonly used non-GAAP and supplemental financial measures.

Forward-Looking Statements

Except for the historical information contained herein, the matters discussed in this release consist of forward-looking statements that involve certain risks and uncertainties that could cause actual results or outcomes to differ materially from results or outcomes anticipated in the forward-looking statements. These risks and uncertainties include, among other things, declines in the volume of crude oil and NGL shipped, processed, purchased, stored, fractionated and/or gathered at or through the use of our assets, whether due to declines in production from existing oil and gas reserves, reduced demand, failure to develop or slowdown in the development of additional oil and gas reserves, whether from reduced cash flow to fund drilling or the inability to access capital, or other factors; the effects of competition; market distortions caused by producer over-commitments to new or recently constructed infrastructure projects, which impacts volumes, margins, returns and overall earnings; unanticipated changes in crude oil market structure, grade differentials and volatility (or lack thereof); environmental liabilities or events that are not covered by an indemnity, insurance or existing reserves; maintenance of our credit rating and ability to receive open credit from our suppliers and trade counterparties; fluctuations in refinery capacity in areas supplied by our mainlines and other factors affecting demand for various grades of crude oil, refined products and natural gas and resulting changes in pricing conditions or transportation throughput requirements; the occurrence of a natural disaster, catastrophe, terrorist attack (including eco-terrorist attacks) or other event, including attacks on our electronic and computer systems; failure to implement or capitalize, or delays in implementing or capitalizing, on expansion projects, whether due to permitting delays, permitting withdrawals or other factors; tightened capital markets or other factors that increase our cost of capital or limit our ability to obtain debt or equity financing on satisfactory terms to fund additional acquisitions, expansion projects, working capital requirements and the repayment or refinancing of indebtedness; the successful integration and future performance of acquired assets or businesses and the risks associated with operating in lines of business that are distinct and separate from our historical operations; the currency exchange rate of the Canadian dollar; continued creditworthiness of, and performance by, our counterparties, including financial institutions and trading companies with which we do business; inability to recognize current revenue attributable to deficiency payments received from customers who fail to ship or move more than minimum contracted volumes until the related credits expire or are used; non-utilization of our assets and facilities; increased costs, or lack of availability, of insurance; weather interference with business operations or project construction, including the impact of extreme weather events or conditions; the availability of, and our ability to consummate, acquisition or combination opportunities; the effectiveness of our risk management activities; shortages or cost increases of supplies, materials or labor; the impact of current and future laws, rulings, governmental regulations, accounting standards and statements, and related interpretations; fluctuations in the debt and equity markets, including the price of our units at the time of vesting under our long-term incentive plans; risks related to the development and operation of our assets, including our ability to satisfy our contractual obligations to our customers; factors affecting demand for natural gas and natural gas storage services and rates; general economic, market or

Diluted net income per common unit	$	0.58		$	0.07

⁽¹⁾

We calculate net income allocated to common unitholders based on the distributions pertaining to the current period’s net income. After adjusting for the appropriate period’s distributions, the remaining undistributed earnings or excess distributions over earnings (“undistributed loss”), if any, are allocated to the general partner, common unitholders and participating securities in accordance with the contractual terms of our partnership agreement in effect for the period and as further prescribed under the two-class method. The Simplification Transactions, which closed on November 15, 2016, simplified our governance structure and permanently eliminated our IDRs and the economic rights associated with our 2% general partner interest. As such, beginning with the distribution pertaining to the fourth quarter of 2016, our general partner is no longer entitled to receive distributions on these interests.


⁽²⁾	The possible conversion of our Series A preferred units was excluded from the calculation of diluted net income per common unit for the three months ended March 31, 2016 as the effect was antidilutive.

⁽³⁾

Our Long-term Incentive Plan (“LTIP”) awards that contemplate the issuance of common units are considered dilutive unless (i) vesting occurs only upon the satisfaction of a performance condition and (ii) that performance condition has yet to be satisfied. LTIP awards that are deemed to be dilutive are reduced by a hypothetical unit repurchase based on the remaining unamortized fair value, as prescribed by the treasury stock method in guidance issued by the FASB.

⁽¹⁾

During the fourth quarter of 2016, we modified our primary segment performance measure to segment adjusted EBITDA from segment profit. Segment adjusted EBITDA forms the basis of our internal financial reporting and is the primary measure used by our Chief Operating Decision Maker (“CODM”) in assessing performance and allocating resources among our operating segments. Prior period segment amounts have been recast to reflect this change.


⁽²⁾	Includes intersegment amounts.


⁽³⁾	Field operating costs and Segment general and administrative expenses exclude equity-indexed compensation expense, which is presented separately in the table above.


⁽⁴⁾	Segment general and administrative expenses reflect direct costs attributable to each segment and an allocation of other expenses to the segments. The proportional allocations by segment require judgment by management and are based on the business activities that exist during each period.


⁽⁵⁾	Represents adjustments utilized by our CODM in the evaluation of segment results. Many of these adjustments are also considered selected items impacting comparability when calculating consolidated non-GAAP financial measures such as Adjusted EBITDA. See the “Selected Items Impacting Comparability” table on the following page for additional discussion.

Impact to basic net income per common unit	$	0.32		$	(0.38	)
Impact to diluted net income per common unit	$	0.31		$	(0.38	)


⁽¹⁾	Certain of our non-GAAP financial measures may not be impacted by each of the selected items impacting comparability.

⁽²⁾

We use derivative instruments for risk management purposes and our related processes include specific identification of hedging instruments to an underlying hedged transaction. Although we identify an underlying transaction for each derivative instrument we enter into, there may not be an accounting hedge relationship between the instrument and the underlying transaction. In the course of evaluating our results of operations, we identify the earnings that were recognized during the period related to derivative instruments for which the identified underlying transaction does not occur in the current period and exclude the related gains and losses in determining adjusted results. In addition, we exclude gains and losses on derivatives that are related to investing activities, such as the purchase of linefill. We also exclude the impact of corresponding inventory valuation adjustments, as applicable, as well as the mark-to-market adjustment related to our Preferred Distribution Rate Reset Option.

⁽³⁾

We carry crude oil and NGL inventory comprised of minimum working inventory requirements in third-party assets and other working inventory that is needed for our commercial operations. We consider this inventory necessary to conduct our operations and we intend to carry this inventory for the foreseeable future. Therefore, we classify this inventory as long-term on our balance sheet and do not hedge the inventory with derivative instruments (similar to linefill in our own assets). We treat the impact of changes in the average cost of the long-term inventory (that result from fluctuations in market prices) and writedowns of such inventory that result from price declines as a selected item impacting comparability.

⁽⁴⁾

We have certain agreements that require counterparties to deliver, transport or throughput a minimum volume over an agreed upon period. Substantially all of such agreements were entered into with counterparties to economically support the return on our capital expenditure necessary to construct the related asset. Some of these agreements include make-up rights if the minimum volume is not met. We record a receivable from the counterparty in the period that services are provided or when the transaction occurs, including amounts for deficiency obligations from counterparties associated with minimum volume commitments. If a counterparty has a make-up right associated with a deficiency, we defer the revenue attributable to the counterparty’s make-up right and subsequently recognize the revenue at the earlier of when the deficiency volume is delivered or shipped, when the make-up right expires or when it is determined that the counterparty’s ability to utilize the make-up right is remote. We include the impact of amounts billed to counterparties for their deficiency obligation, net of applicable amounts subsequently recognized into revenue, as a selected item impacting comparability. We believe the inclusion of the contractually committed revenues associated with that period is meaningful to investors as the related asset has been constructed, is standing ready to provide the committed service and the fixed operating costs are included in the current period results.

⁽⁵⁾

Our total equity-indexed compensation expense includes expense associated with awards that will or may be settled in units and awards that will or may be settled in cash. The awards that will or may be settled in units are included in our diluted net income per unit calculation when the applicable performance criteria have been met. We consider the compensation expense associated with these awards as a selected item impacting comparability as the dilutive impact of the outstanding awards is included in our diluted net income per unit calculation and the majority of the awards are expected to be settled in units. The portion of compensation expense associated with awards that are certain to be settled in cash is not considered a selected item impacting comparability.


⁽⁶⁾	During the periods presented, there were fluctuations in the value of the Canadian dollar to the U.S. dollar, resulting in gains and losses that were not related to our core operating results for the period and were thus classified as a selected item impacting comparability.


⁽⁷⁾	Includes acquisition-related expenses associated with the Alpha Crude Connector acquisition.

⁽¹⁾

We calculate adjusted net income allocated to common unitholders based on the distributions pertaining to the current period’s net income. After adjusting for the appropriate period’s distributions, the remaining undistributed earnings or excess distributions over earnings (“undistributed loss”), if any, are allocated to the general partner, common unitholders and participating securities in accordance with the contractual terms of our partnership agreement in effect for the period and as further prescribed under the two-class method. The Simplification Transactions, which closed on November 15, 2016, simplified our governance structure and permanently eliminated our IDRs and the economic rights associated with our 2% general partner interest. As such, beginning with the distribution pertaining to the fourth quarter of 2016, our general partner is no longer entitled to receive distributions from these interests.


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

⁽³⁾


⁽⁴⁾	The possible conversion of our Series A preferred units was excluded from the calculation of diluted adjusted net income per common unit for the three months ended March 31, 2017 and 2016 as the effect was antidilutive.
