**Note 1—Organization and Basis of Consolidation and Presentation**

***Organization***

Plains All American Pipeline, L.P. ("PAA") is a Delaware limited partnership formed in 1998. Our operations are conducted directly and indirectly through our primary operating subsidiaries. As used in this Form 10-Q and unless the context indicates otherwise, the terms "Partnership," "we," "us," "our," "ours" and similar terms refer to PAA and its subsidiaries.

Our business model integrates large-scale supply aggregation capabilities with the ownership and operation of critical midstream infrastructure systems that connect major producing regions to key demand centers and export terminals. As one of the largest crude oil midstream service providers in North America, we own an extensive network of pipeline transportation, terminalling, storage and gathering assets in key crude oil producing basins (including the Permian Basin) and transportation corridors and at major market hubs in the United States and Canada. Our assets and the services we provide are primarily focused on and conducted through two operating segments: Crude Oil and Natural Gas Liquids ("NGL"). See Note 11 for further discussion of our operating segments.

Our non-economic general partner interest is held by PAA GP LLC ("PAA GP"), a Delaware limited liability company, whose sole member is Plains AAP, L.P. ("AAP"), a Delaware limited partnership. In addition to its ownership of PAA GP, as of September 30, 2025, AAP also owned a limited partner interest in us through its ownership of approximately 233.0 million of our common units (approximately 31% of our total outstanding common units and Series A preferred units combined). Plains All American GP LLC ("GP LLC"), a Delaware limited liability company, is AAP's general partner. Plains GP Holdings, L.P. ("PAGP") is the sole and managing member of GP LLC, and, at September 30, 2025, owned an approximate 85% limited partner interest in AAP. PAA GP Holdings LLC ("PAGP GP") is the general partner of PAGP.

As the sole member of GP LLC, PAGP has responsibility for conducting our business and managing our operations; however, the board of directors of PAGP GP has ultimate responsibility for managing the business and affairs of PAGP, AAP and us. GP LLC employs our domestic officers and personnel; our Canadian officers and personnel are employed by our subsidiary, Plains Midstream Canada ULC.

References to our "general partner," as the context requires, include any or all of PAGP GP, PAGP, GP LLC, AAP and PAA GP. References to "Plains entities," as the context requires, include any or all of PAA and its subsidiaries and our general partner.

***Basis of Consolidation and Presentation***

The accompanying unaudited condensed consolidated interim financial statements and related notes thereto should be read in conjunction with our 2024 Annual Report on Form 10-K. The accompanying condensed consolidated financial statements include the accounts of PAA and all of its wholly owned subsidiaries and those entities that it controls. Investments in entities over which we have significant influence but not control are accounted for by the equity method. We apply proportionate consolidation for pipelines and other assets in which we own undivided joint interests. The financial statements have been prepared in accordance with the instructions for interim reporting as set forth by the SEC. The condensed consolidated balance sheet data as of December 31, 2024 was derived from audited financial statements, but does not include all disclosures required by GAAP. The results of operations for the three and nine months ended September 30, 2025 should not be taken as indicative of results to be expected for the entire year. All adjustments (consisting only of normal recurring adjustments) that in the opinion of management were necessary for a fair statement of the results for the interim periods have been reflected. All significant intercompany balances and transactions have been eliminated in consolidation, and certain reclassifications have been made to information from previous years to conform to the current presentation. These reclassifications had no impact on net income or total partners' capital.

**NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

*Pending Sale of Canadian NGL Business*

On June 17, 2025, we entered into a definitive Share Purchase Agreement ("SPA") with Keyera Corp. ("Keyera"), an Alberta corporation, pursuant to which Keyera agreed to acquire all of the issued and outstanding shares of Plains Midstream Canada ULC, our wholly-owned subsidiary that owns substantially all of our NGL business in Canada (the "Canadian NGL Business"), for cash consideration of approximately CAD$5.15 billion (approximately $3.75 billion), subject to certain post-closing adjustments, as defined in the SPA. This transaction is expected to close in the first quarter of 2026, subject to the satisfaction or waiver of customary closing conditions, including receipt of regulatory approvals.

We determined that in conjunction with entering into the SPA, the operations of the Canadian NGL Business meet the criteria for classification as held for sale and for discontinued operations reporting, as the sale will represent a strategic shift that will have a major effect on our operations and financial results. Accordingly, the assets and liabilities of the Canadian NGL Business have been classified as held for sale, and the balance sheet, results of operations and cash flows of the Canadian NGL Business have been presented as discontinued operations in our condensed consolidated financial statements. Unless otherwise indicated, the disclosures included within the accompanying notes to the condensed consolidated financial statements relate to our continuing operations and exclude amounts related to discontinued operations. These changes have been applied retrospectively to all periods presented. Discontinued operations are not presented separately within our Condensed Consolidated Statements of Comprehensive Income, Condensed Consolidated Statements of Changes in Accumulated Other Comprehensive Income/(Loss) or the Condensed Consolidated Statements of Changes in Partners' Capital. See Note 2 for additional information regarding discontinued operations. All significant intercompany balances and transactions between the Canadian NGL Business and our continuing operations have been eliminated.

While we will divest the Canadian NGL Business as part of the sale, we will retain substantially all NGL assets in the United States and will also retain all crude oil assets in Canada. Prior to its classification as held for sale and presentation as discontinued operations, the Canadian NGL Business was part of our NGL reportable segment.

In June 2025, we entered into a forward currency instrument to hedge currency exchange risk associated with anticipated proceeds from the pending sale of our Canadian NGL Business. See Note 8 for additional information.

In connection with and contingent upon closing of the pending sale, we and Keyera entered into an agreement for certain hedging arrangements and payments relating to the differential between the price of natural gas and the extracted NGL commodities ("Frac Spread") for a twelve-month period commencing the first month after the closing date. As a result of this arrangement, we will guarantee a minimum Frac Spread margin on certain volumes. The recognition of an asset or liability will be dependent upon the terms of the specific contracts transferred as part of the sale of the Canadian NGL Business and the market conditions at that time the sale closes. We do not expect any liability we might recognize as a result of this agreement to have a material adverse effect on our consolidated financial condition, results of operations or cash flows; for example, if the sale closed during the first quarter of 2026, based on existing contracts to be transferred and current market conditions as of September 30, 2025, we would recognize a liability of approximately $45 million.

***Subsequent Events***

Subsequent events have been evaluated through the financial statements issuance date and have been included in the following footnotes where applicable.

***Recent Accounting Pronouncements, Disclosure Rules and Other Legislation***

Except as discussed in our 2024 Annual Report on Form 10-K, there have been no new accounting pronouncements that have become effective or have been issued during the nine months ended September 30, 2025 that are of significance or potential significance to us.

**Note 2*—* Discontinued Operations**

The operations of the Canadian NGL Business meet the criteria for classification as held for sale and for discontinued operations reporting. The Canadian NGL Business disposal group is recorded at its historical carrying value, as the fair value of the disposal group, less estimated costs to sell, is greater than the carrying value of the Canadian NGL Business disposal group. Depreciation and amortization on the long-lived assets of the Canadian NGL Business disposal group ceased upon meeting the criteria to be classified as assets held for sale. See Note 1 for information regarding the pending sale of the Canadian NGL Business.

The following table summarizes the carrying amounts of major classes of assets and liabilities of discontinued operations (in millions):

**NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

*Sales Revenues.* Revenues from sales of crude oil and NGL are recognized at the time title to the product sold transfers to the purchaser, which occurs upon delivery of the product to the purchaser or its designee. The consideration received under these contracts is variable based on commodity prices. Inventory exchanges under buy/sell transactions are excluded from sales revenues in our Condensed Consolidated Statements of Operations.

*Transportation Revenues.* Transportation revenues include revenues from transporting crude oil on pipelines and trucks. Revenues from pipeline tariffs and fees are associated with the transportation of crude oil at a published tariff. We primarily recognize pipeline tariff and fee revenues over time as services are rendered, based on the volumes transported. As is common in the pipeline transportation industry, our tariffs incorporate a loss allowance factor. We recognize the allowance volumes collected as part of the transaction price and record this non-cash consideration at fair value, measured as of the contract inception date.

*Terminalling, Storage and Other Revenues.* Revenues in this category include (i) fees that are generated when we receive liquids from one connecting source and deliver the applicable product to another connecting carrier, (ii) fees from storage capacity agreements, (iii) fees from loading and unloading services at our terminals and (iv) fees from natural gas and condensate processing services. We generate revenue through a combination of month-to-month and multi-year agreements and processing arrangements. Storage fees are typically recognized in revenue ratably over the term of the contract regardless of the actual storage capacity utilized as our performance obligation is to make available storage capacity for a period of time. Terminal fees (including throughput and loading/unloading fees) are recognized as the liquids enter or exit the terminal and are received from or delivered to the connecting carrier or third-party terminal, as applicable. We recognize loading and unloading fees when the volumes are delivered or received.

*Reconciliation to Total Revenues of Reportable Segments.* The following disclosures only include information regarding revenues associated with consolidated entities; revenues from entities accounted for by the equity method are not included. The following tables present the reconciliation of our revenues from contracts with customers to total revenues of reportable segments and total revenues as disclosed in our Condensed Consolidated Statements of Operations (in millions):

**Note 4—Net Income Per Common Unit**

We calculate basic and diluted net income per common unit by dividing income from continuing operations attributable to PAA (after deducting amounts allocated to the preferred unitholders and participating securities) and income from discontinued operations by the basic and diluted weighted average number of common units outstanding during the period.

The diluted weighted average number of common units is computed based on the weighted average number of common units plus the effect of potentially dilutive securities outstanding during the period, which include (i) our Series A preferred units and (ii) our equity-indexed compensation plan awards. See Note 11 and Note 17 to our Consolidated Financial Statements included in Part IV of our 2024 Annual Report on Form 10-K for a discussion of our Series A preferred units and equity-indexed compensation plan awards. When applying the if-converted method prescribed by FASB guidance, on a weighted-average basis, for the three and nine months ended September 30, 2025, the possible conversion of approximately 58 million and 60 million Series A preferred units, respectively, and for each of the three and nine months ended September 30, 2024, the possible conversion of approximately 71 million Series A preferred units were excluded from the calculation of diluted net income per common unit as the effect was antidilutive. Our equity-indexed compensation plan awards that contemplate the issuance of common units are considered potentially dilutive unless (i) they become vested only upon the satisfaction of a performance condition and (ii) that performance condition has yet to be satisfied. Equity-indexed compensation plan awards that are deemed to be dilutive during the period are reduced by a hypothetical common unit repurchase based on the remaining unamortized fair value, as prescribed by the treasury stock method in guidance issued by the FASB.

<sup>(1)</sup> We repurchased approximately 12.7 million Series A preferred units on January 31, 2025. See Note 7 for additional information. The difference between the cash we paid for the repurchase of such units and their carrying value on our balance sheet is considered a return to Series A preferred unitholders for the calculation of net income allocated to common unitholders.

<sup>(2)</sup> We calculate net income from continuing operations 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 (i.e., undistributed loss), if any, are allocated to the 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.

<sup>(3)</sup> Net income from discontinued operations allocated to common unitholders is Income from discontinued operations, net of tax as presented on our Condensed Consolidated Statements of Operations.

<sup>(1)</sup> We classified these commercial paper notes as short-term as of December 31, 2024, as these notes were primarily designated as working capital borrowings, were required to be repaid within one year and were primarily for hedged inventory and NYMEX and ICE margin deposits.

<sup>(2)</sup> As of December 31, 2024, we classified our $1.0 billion, 4.65% senior notes due October 2025 as long-term based on our ability and intent to refinance the notes on a long-term basis at that time. We redeemed these senior notes on October 3, 2025.

<sup>(3)</sup> Our fixed-rate senior notes had a face value of approximately $9.4 billion and $7.2 billion as of September 30, 2025 and December 31, 2024, respectively. We estimated the aggregate fair value of these notes as of September 30, 2025 and December 31, 2024 to be approximately $9.2 billion and $6.7 billion, respectively. Our fixed-rate senior notes are traded among institutions, and these trades are routinely published by a reporting service. Our determination of fair value is based on reported trading activity near the end of the reporting period. We estimate that the carrying value of outstanding borrowings under our commercial paper program approximates fair value as interest rates reflect current market rates. The fair value estimates for our senior notes and commercial paper program are based upon observable market data and are classified in Level 2 of the fair value hierarchy.

***Senior Notes***

In January 2025, we completed the offering of $1.0 billion, 5.95% senior notes due June 2035 at a public offering price of 99.761%. Interest payments are due on June 15 and December 15 of each year, commencing on June 15, 2025.

In September 2025, we completed the offering of $700 million, 4.70% senior notes due January 2031 and $550 million, 5.60% senior notes due January 2036 at a public offering price of 99.865% and 99.798%, respectively. Interest payments on these notes are due on January 15 and July 15 of each year, commencing on January 15, 2026.

***Borrowings and Repayments***

Total borrowings under our commercial paper program for the nine months ended September 30, 2025 and 2024 were approximately $38.7 billion and $20.7 billion, respectively. Total repayments under our commercial paper program were approximately $39.1 billion and $21.1 billion for the nine months ended September 30, 2025 and 2024, respectively. The variance in total gross borrowings and repayments is impacted by various business and financial factors including, but not limited to, the timing, average term and method of general partnership borrowing activities.

***Repurchase of Series A Preferred Units***

On January 31, 2025, we repurchased approximately 12.7 million of our outstanding Series A preferred units from EnCap Flatrock Midstream at the issue price of $26.25 per unit for a purchase price of approximately $333 million, plus accrued and unpaid distributions through January 30, 2025 of approximately $10 million. EnCap Flatrock Midstream is affiliated with EnCap Investments, L.P., an entity that is associated with a member of the board of directors of PAGP GP. The repurchase also resulted in a reduction to the related Preferred Distribution Rate Reset Option liability. See Note 12 to our Consolidated Financial Statements included in Part IV of our 2024 Annual Report on Form 10-K for additional information regarding the Preferred Distribution Rate Reset Option. The difference between the cash we paid for the repurchase of such units and their carrying value on our balance sheet was $43 million. Such amount was considered a return to Series A preferred unitholders and thus reduced amounts attributable to our common unitholders in our Condensed Consolidated Statement of Changes in Partners' Capital and the calculation of net income per common unit.

**Note 8—Derivatives and Risk Management Activities**

We identify the risks that underlie our core business activities and use risk management strategies to mitigate those risks when we determine that there is value in doing so. We use various derivative instruments to manage our exposure to commodity price risk, interest rate risk, and currency exchange rate risk. Our commodity price risk management policies and procedures are designed to help ensure that our hedging activities address our risks by monitoring our derivative positions, as well as physical volumes, grades, locations, delivery schedules and storage capacity. Our interest rate risk and currency exchange rate risk management policies and procedures are designed to monitor our derivative positions and ensure that those positions are consistent with our objectives and approved strategies. Our policy is to use derivative instruments for risk management purposes and not for the purpose of speculating on changes in commodity prices or interest rates. When we apply hedge accounting, our policy is to formally document all relationships between hedging instruments and hedged items, as well as our risk management objectives for undertaking the hedge. This process includes specific identification of the hedging instrument and the hedged transaction, the nature of the risk being hedged and how the hedging instrument's effectiveness will be assessed. At the inception of the hedging relationship, we assess whether the derivatives employed are highly effective in offsetting changes in cash flows of anticipated hedged transactions. Throughout the hedging relationship, retrospective and prospective hedge effectiveness is assessed on a qualitative basis.

------

<u>[**Table of Contents**](#i29a905161dd64cdb968dbc606bd49e76_7)</u> 

**PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES**

**NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

We record all open derivatives on the balance sheet as either assets or liabilities measured at fair value. Changes in the fair value of derivatives are recognized currently in earnings unless specific hedge accounting criteria are met. For derivatives designated as cash flow hedges, changes in fair value are deferred in AOCI and recognized in earnings in the periods during which the underlying hedged transactions are recognized in earnings. Derivatives that are not designated in a hedging relationship for accounting purposes are recognized in earnings each period. Cash settlements associated with our derivative activities are classified within the same category as the related hedged item in our Condensed Consolidated Statements of Cash Flows.

Our financial derivatives, used for hedging risk, are governed through ISDA master agreements and clearing brokerage agreements. These agreements include stipulations regarding the right of set off in the event that we or our counterparty default on performance obligations. If a default were to occur, both parties have the right to net amounts payable and receivable into a single net settlement between parties.

At September 30, 2025 and December 31, 2024, none of our outstanding derivatives contained credit-risk related contingent features that would result in a material adverse impact to us upon any change in our credit ratings. Although we may be required to post margin on our exchange-traded derivatives transacted through a clearing brokerage account, as described below, we do not require our non-cleared derivative counterparties to post collateral with us.

***Commodity Price Risk Hedging***

Our core business activities involve certain commodity price-related risks that we manage in various ways, including through the use of derivative instruments. Our policy is to (i) only purchase inventory for which we have a sales market, (ii) structure our sales contracts so that price fluctuations do not materially affect our operating income and (iii) not acquire and hold material physical inventory or derivatives for the purpose of speculating on commodity price changes. The material commodity-related risks inherent in our business activities are described below.

In the normal course of our operations, we purchase and sell commodities. We use derivatives to manage the associated risks and, in certain circumstances, to optimize profits. As of September 30, 2025, net derivative positions related to these activities included:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A net long position of 9.4 million barrels associated with our crude oil purchases, which will be unwound ratably through December 2025 to match monthly average pricing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A net short time spread position of 2.1 million barrels, which hedges a portion of our anticipated crude oil lease gathering purchases through April 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A net crude oil basis spread position of 2.5 million barrels at multiple locations through December 2026. These derivatives allow us to lock in grade and location basis differentials.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A net short position of 5.7 million barrels through December 2029 related to anticipated net sales of crude oil inventory.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A net long position of 0.5 TWh through December 2030 related to anticipated power supply requirements.

Physical commodity contracts that meet the definition of a derivative but are ineligible, or not designated, for the normal purchases and normal sales scope exception are recorded on the balance sheet at fair value, with changes in fair value recognized in earnings. We have determined that substantially all of our physical commodity contracts qualify for the normal purchases and normal sales scope exception.

Our accounting policy is to offset derivative assets and liabilities executed with the same counterparty when a master netting arrangement exists. Accordingly, we also offset derivative assets and liabilities with amounts associated with cash margin. Our exchange-traded derivatives are transacted through clearing brokerage accounts and are subject to margin requirements as established by the respective exchange. On a daily basis, our account equity (consisting of the sum of our cash balance and the fair value of our open derivatives) is compared to our initial margin requirement resulting in the payment or return of variation margin.

***Interest Rate Risk Hedging***

We use interest rate derivatives to hedge the benchmark interest rate associated with interest payments occurring as a result of debt issuances. The derivative instruments we use to manage this risk consist of forward starting interest rate swaps and treasury locks. These derivatives are designated as cash flow hedges. As such, changes in fair value are deferred in AOCI and are reclassified to interest expense as we incur the interest expense associated with the underlying debt.

| Anticipated interest payments | 8 forward starting swaps<br>(30-year) | $200 | 6/15/2026 | 3.09% | Cash flow hedge |

---

During the three months ended September 30, 2025, we terminated $200 million of notional hedging instruments for proceeds of $7 million, which was recorded in AOCI. As of September 30, 2025, there was a net loss of $31 million deferred in AOCI. The deferred net loss recorded in AOCI is expected to be reclassified to future earnings contemporaneously with interest expense accruals associated with underlying debt instruments. We estimate that substantially all of the remaining deferred loss will be reclassified to earnings through 2056 as the underlying hedged transactions impact earnings. A portion of these amounts is based on market prices as of September 30, 2025; thus, actual amounts to be reclassified will differ and could vary materially as a result of changes in market conditions.

The following table summarizes the net unrealized gain/(loss) recognized in AOCI for derivatives (in millions):

At September 30, 2025, the net fair value of our interest rate hedges, which was included in "Other current assets" on our Condensed Consolidated Balance Sheet, totaled $29 million. At December 31, 2024, the net fair value of our interest rate hedges, which was included in "Other long-term assets, net" on our Condensed Consolidated Balance Sheet, totaled $27 million.

***Currency Exchange Rate Risk Hedging***

In connection with the pending sale of the Canadian NGL Business, we entered into a forward currency instrument (CAD$4.5 billion notional amount) to hedge currency exchange risk. The instrument is contingent upon the sale occurring and will settle at closing. The cost of the deal-contingent structure is embedded in the hedge rate. As of September 30, 2025, the sale of the Canadian NGL Business is probable and the fair value of the instrument is a $41 million asset, presented in "Other current assets" on our Condensed Consolidated Balance Sheet. For the three and nine months ended September 30, 2025, we recognized the gains of $90 million and $41 million, respectively, which was included in "(Gains)/losses on asset sales, net" on our Condensed Consolidated Statements of Operations. As of September 30, 2025, for the periods covered by the instrument, the average fixed USD to CAD rate of the instrument is $1.37 and the average forward USD to CAD rate is $1.38. See Note 1 for additional information regarding the pending sale of the Canadian NGL Business.

<sup>(1)</sup> Derivative assets and liabilities are presented above on a net basis but do not include related cash margin deposits.

***Level 1***

Level 1 of the fair value hierarchy includes exchange-traded commodity derivatives and over-the-counter commodity contracts such as futures and swaps. The fair value of exchange-traded commodity derivatives and over-the-counter commodity contracts is based on unadjusted quoted prices in active markets.

***Level 2***

Level 2 of the fair value hierarchy includes exchange-cleared commodity derivatives, over-the-counter commodity, foreign exchange and interest rate derivatives that are traded in observable markets with less volume and transaction frequency than active markets. In addition, it includes certain physical commodity contracts. The fair values of these derivatives are corroborated with market observable inputs.

**Note 9—Related Party Transactions**

See Note 16 to our Consolidated Financial Statements included in Part IV of our 2024 Annual Report on Form 10-K for a complete discussion of related parties, including the determination of our related parties and nature of involvement with such related parties.

***Promissory Notes with our General Partner***

In February 2025, a consolidated subsidiary issued an additional unsecured promissory note to PAGP with a face value of CAD$473 million (approximately $330 million). Concurrently, PAGP issued an unsecured promissory note to us for the same face value amount. These notes are due June 2035 and bear interest at a rate of 5.75% per annum, payable semi-annually. The interest rate for such notes was determined in accordance with the arm's-length principle set forth in the OECD Guidelines and the transfer pricing provisions of Section 247 of Canada's Income Tax Act. In connection with the issuance of these related party notes, we received cash from PAGP of approximately $330 million, which is reflected in "Proceeds from the issuance of related party notes" (a component of cash flows from financing activities), and we paid an equal and offsetting amount of cash to PAGP, which is reflected in "Investments in related party notes" (a component of cash flows from investing activities) on our Condensed Consolidated Statement of Cash Flows.

Accrued and unpaid interest receivable/payable was $7 million and $27 million as of September 30, 2025 and December 31, 2024, respectively. Interest income/expense on the related party notes totaled $23 million and $65 million for the three and nine months ended September 30, 2025, respectively, and $16 million and $31 million for the three and nine months ended September 30, 2024, respectively.

As of September 30, 2025 and December 31, 2024, our outstanding related party notes receivable and related party notes payable balances were as follows (in millions):

| Related party notes receivable <sup>(1)</sup> | $1321 | $948 |
| Related party notes payable <sup>(1)</sup> | $1321 | $948 |

---

<sup>(1)</sup> We have elected to present our related party notes with the same counterparty on a net basis on our Condensed Consolidated Balance Sheet because there is a legal right to offset and we intend to offset with the counterparty.

***Loss Contingencies — General***

To the extent we are able to assess the likelihood of a negative outcome for a contingency, our assessments of such likelihood range from remote to probable. If we determine that a negative outcome is probable and the amount of loss is reasonably estimable, we accrue an undiscounted liability equal to the estimated amount. If a range of probable loss amounts can be reasonably estimated and no amount within the range is a better estimate than any other amount, then we accrue an undiscounted liability equal to the minimum amount in the range. In addition, we estimate legal fees that we expect to incur associated with loss contingencies and accrue those costs when they are material and probable of being incurred.

We do not record a contingent liability when the likelihood of loss is probable but the amount cannot be reasonably estimated or when the likelihood of loss is believed to be only reasonably possible or remote. For contingencies where an unfavorable outcome is reasonably possible and the impact would be material to our consolidated financial statements, we disclose the nature of the contingency and, where feasible, an estimate of the possible loss or range of loss.

***Legal Proceedings — General***

In the ordinary course of business, we are involved in various legal proceedings including those arising from regulatory and environmental matters. In connection with determining the probability of loss associated with such legal proceedings and whether any potential losses associated therewith are estimable, we take into account what we believe to be all relevant known facts and circumstances, and what we believe to be reasonable assumptions regarding the application of those facts and circumstances to existing agreements, laws and regulations. Although we are insured against various risks to the extent we believe it is prudent, there is no assurance that the nature and amount of such insurance will be adequate, in every case, to fully protect us from losses arising from current or future legal proceedings.

**NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

Accordingly, we can provide no assurance that the outcome of the various legal proceedings that we are currently involved in, or will become involved with in the future, will not, individually or in the aggregate, have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

***Environmental — General***

We currently own or lease, and in the past have owned and leased, properties where hazardous liquids, including hydrocarbons, are or have been handled. These properties and the hazardous liquids or associated wastes disposed thereon may be subject to the U.S. federal Comprehensive Environmental Response, Compensation and Liability Act, as amended, and the U.S. federal Resource Conservation and Recovery Act, as amended, as well as state and Canadian federal and provincial laws and regulations. Under such laws and regulations, we could be required to remove or remediate hazardous liquids or associated wastes (including wastes disposed of or released by prior owners or operators) and to clean up contaminated property (including contaminated groundwater). Assets we have acquired or will acquire in the future may have environmental remediation liabilities for which we are not indemnified or insured.

Although we have made significant investments in our maintenance and integrity programs, we have experienced (and likely will experience future) releases of hydrocarbon products into the environment from our pipeline, rail, storage and other facility operations. These releases can result from accidents or from unpredictable man-made or natural forces and may reach surface water bodies, groundwater aquifers or other sensitive environments. We also may discover environmental impacts from past releases that were previously unidentified. Damages and liabilities associated with any such releases from our existing or future assets could be significant and could have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

We record environmental liabilities when environmental assessments and/or remedial efforts are probable and the amounts can be reasonably estimated. Generally, our recording of these liabilities coincides with our completion of a feasibility study or our commitment to a formal plan of action. We do not discount our environmental remediation liabilities to present value. We also record environmental liabilities assumed in business combinations based on the estimated fair value of the environmental obligations caused by past operations of the acquired company. We record receivables for amounts we believe are recoverable from insurance or from third parties under indemnification agreements in the period that we determine the costs are probable of recovery.

Environmental expenditures that pertain to current operations or to future revenues are expensed or capitalized consistent with our capitalization policy for property and equipment. Expenditures that result from the remediation of an existing condition caused by past operations and that do not contribute to current or future profitability are expensed.

Our estimated undiscounted reserves for environmental liabilities (excluding liabilities related to the Line 901 incident, as discussed further below) were reflected on our Condensed Consolidated Balance Sheets as follows (in millions):

---

| | | |
|:---|:---|:---|
| | **September 30,<br>2025** | **December 31,<br>2024** |
| Other current liabilities | $15 | $11 |
| Other long-term liabilities and deferred credits | 73 | 69 |
| &nbsp;&nbsp;Total | $88 | $80 |

---

In some cases, the actual cash expenditures associated with these liabilities may not occur for several years. Our estimates used in determining these reserves are based on information currently available to us and our assessment of the ultimate outcome. Among the many uncertainties that impact our estimates are the necessary regulatory approvals for, and potential modification of, our remediation plans, the limited amount of data available upon initial assessment of the impact of soil or water contamination, changes in costs associated with environmental remediation services and equipment and the possibility of existing or future legal claims giving rise to additional liabilities. Therefore, although we believe that our reserves are adequate, actual costs incurred (which may ultimately include costs for contingencies that are currently not reasonably estimable or costs for contingencies where the likelihood of loss is currently believed to be only reasonably possible or remote) may be in excess of such reserves and may potentially have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

***Specific Legal, Environmental or Regulatory Matters***

*Line 901 Incident*. In May 2015 we experienced a release of crude oil from our Las Flores to Gaviota Pipeline (Line 901) in Santa Barbara County, California. Effective as of September 30, 2025, we estimate that the aggregate total costs we have incurred or will incur with respect to the Line 901 incident will be approximately $870 million, which includes actual emergency response and clean-up costs, natural resource damage assessments, fines and penalties incurred, certain third-party claims settlements, and estimated costs associated with our remaining Line 901 lawsuits and claims as described below, as well as estimates for certain legal fees and statutory interest where applicable. We accrue such estimates of aggregate total costs to "Field operating costs" in our Condensed Consolidated Statements of Operations. This estimate considers our prior experience in environmental investigation and remediation matters and available data from, and in consultation with, our environmental and other specialists, as well as currently available facts and presently enacted laws and regulations. We have made assumptions for (i) the resolution of certain third-party claims and lawsuits, but excluding claims and lawsuits with respect to which losses are not probable and reasonably estimable, and (ii) the nature, extent and cost of legal services that will be required in connection with all lawsuits, claims and other matters requiring legal or expert advice associated with the Line 901 incident. Our estimate does not include any lost revenue associated with the shutdown of Line 901 or 903 and does not include any liabilities or costs that are not reasonably estimable at this time or that relate to contingencies where we currently regard the likelihood of loss as being only reasonably possible or remote. We believe we have accrued adequate amounts for all probable and reasonably estimable costs; however, this estimate is subject to uncertainties associated with the assumptions that we have made. For example, with respect to potential losses that we regard as only reasonably possible or remote, we have made assumptions regarding the strength of our legal position based on our assessment of the relevant facts and applicable law and precedent; if our assumptions regarding such matters turn out to be inaccurate (i.e., we are found to be liable under circumstances where we regard the likelihood of loss as being only reasonably possible or remote), we could be responsible for significant costs and expenses that are not currently included in our estimates and accruals. In addition, for any potential losses that we regard as probable and for which we have accrued an estimate of the potential losses, our estimates regarding damages, legal fees, court costs and interest could turn out to be inaccurate and the actual losses we incur could be significantly higher than the amounts included in our estimates and accruals. Also, the amount of time it takes for us to resolve all of the current and future lawsuits and claims that relate to the Line 901 incident could turn out to be significantly longer than we have assumed, and as a result the costs we incur for legal services could be significantly higher than we have estimated. Accordingly, our assumptions and estimates may turn out to be inaccurate and our total costs could turn out to be materially higher; therefore, we can provide no assurance that we will not have to accrue significant additional costs in the future with respect to the Line 901 incident.

During the nine months ended September 30, 2025, we did not recognize any costs related to the Line 901 incident. During the nine months ended September 30, 2024, we recognized costs, net of amounts probable of recovery from insurance (as applicable) of $120 million. As of September 30, 2025 and December 31, 2024, we had a remaining undiscounted gross liability of approximately $3 million and $5 million, respectively, related to the Line 901 incident, which aggregate amounts are reflected in "Current liabilities" on our Condensed Consolidated Balance Sheet.

We maintain insurance coverage, which is subject to certain exclusions and deductibles, in the event of such liabilities. To date, we have collected approximately $275 million of the $500 million available under our 2015 insurance program. We have submitted insurance claims seeking reimbursement for additional legal fees and settlements relating to the Line 901 incident. Such claims, in the aggregate, exceed the $215 million of insurance coverage remaining under the 2015 program. Since we lack certainty at this time as to if or when these claims will be reimbursed by the carriers, we have elected not to accrue for a receivable in connection with these claims. As such, with respect to the Line 901 incident, we do not have any amounts recorded as receivables that are recognized on our Condensed Consolidated Balance Sheets as of September 30, 2025 and December 31, 2024.

**NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

We have completed the required clean-up and remediation work with respect to the Line 901 incident; however, we expect to make payments for additional legal and professional costs during future periods. During the second quarter of 2025, we agreed to confidential settlement terms for various lawsuits filed in California Superior Court in Santa Barbara County by companies and individuals who provided labor, goods, or services associated with oil production activities they claim were disrupted following the Line 901 incident, the agreed aggregate settlement amount has been factored into our Line 901 total cost estimate. The only other remaining Line 901 lawsuit is pending in California Superior Court in Santa Barbara County, in which a landowner on an adjacent pipeline is alleging property damage from the "stigma" of the Line 901 incident. We are vigorously defending this remaining lawsuit, which has not yet been set for trial, and believe we have strong defenses. Taking into account the costs that we have included in our total estimate of costs for the Line 901 incident and considering what we regard as very strong defenses to the claims made in our remaining Line 901 lawsuits, we do not believe the ultimate resolution of such remaining lawsuit will have a material adverse effect on our consolidated financial condition, results of operations or cash flows.

*L48 Pipeline Release.* In March of 2025, our subsidiary, Pacific Pipeline System LLC, experienced a crude oil release of approximately 125 barrels on a segment of the Line 48 pipeline in Carson, California. Clean-up and remediation activities were conducted in cooperation with applicable state and federal regulatory agencies. An investigation by the California Office of the State Fire Marshall is not complete. To date no charges, fines or penalties have been assessed against us with respect to this release; however, it is possible that charges, fines or penalties may be assessed against us in the future. We provided notification to our applicable insurance carriers and intend to pursue reimbursement of any costs incurred in excess of our $10 million self-insured retention. We estimate that the aggregate cost to clean-up and remediate the site will be approximately $20 million. Through September 30, 2025, we incurred $12 million in connection with clean-up and remediation activities.

*Other Litigation Matters: Hartree.* On July 19, 2022, Hartree Natural Gas Storage, LLC ("Hartree") filed a lawsuit under seal in the Superior Court for the State of Delaware asserting claims against PAA Natural Gas Storage, L.P. and PAA arising out of a Membership Interest Purchase Agreement relating to the 2021 sale of the Pine Prairie Energy Center natural gas storage facility to Hartree. In early 2025, we entered into a settlement agreement with Hartree; the terms of the settlement are confidential and the amount paid is not material to our operations. All of Hartree's claims were dismissed with prejudice and without any admission of wrongdoing by Plains.

*Louisiana Coastal Erosion Lawsuit.* Various coastal parishes, the State of Louisiana and some of its departments have filed lawsuits in Louisiana against a number of energy companies seeking damages for coastal erosion in connection with oil and gas operations in Louisiana. One of our subsidiaries has been named in such a lawsuit filed by The Louisiana Department of Wildlife and Fisheries ("LADWF"). LADWF filed a lawsuit in the 24th Judicial District Court of Jefferson Parish, Louisiana on October 30, 2023 against our subsidiary, Plains Pipeline, L.P., Chevron Pipe Line Company, BP Oil Pipeline Company and Arrowhead Gulf Coast Pipeline, LLC (collectively, "Defendants"), as the former and current parties to certain pipeline right of way agreements ("ROWs") in the vicinity of the Elmer Island Wildlife Refuge. LADWF alleges that the Defendants breached the terms of the ROWs by failing to prevent erosion and seeks restoration of the Wildlife Refuge or alternatively monetary compensatory damages including restoration costs, legal fees and disgorgement of profits derived from the alleged trespass. Our subsidiary owned and operated a pipeline in the vicinity of the refuge from 2006 through 2016. In October 2025, the court limited the time period for which LADWF may pursue damages to the period of its ownership of the subject property, which began in 2014. We believe the claims in the lawsuit lack merit and intend to vigorously defend this lawsuit in coordination with the other Defendants.

**Note 11—Segment Information**

Our operating segments, Crude Oil and NGL, which are also our reportable segments, are organized by product as our Crude Oil and NGL businesses are generally impacted by different market fundamentals and require the use of different assets and business strategies. The Crude Oil segment includes our crude oil pipelines, crude oil storage and marine terminals and related crude oil marketing activities. Our crude oil marketing activities are included in our Crude Oil reporting segment as its primary purpose is to support the utilization of our assets by entering into transactions that facilitate increased volumes handled by our assets, resulting in additional earnings for the segment. The NGL segment includes our four NGL assets located in the United States.

Our CODM (our Chief Executive Officer) evaluates segment performance based on measures including Segment Adjusted EBITDA (as defined below). The measure of Segment Adjusted EBITDA forms the basis of our internal financial reporting and is the primary performance measure of segment profit/(loss) used by our CODM in assessing performance and allocating resources among our operating segments. We define Segment Adjusted EBITDA as revenues and equity earnings in unconsolidated entities less (a) significant segment expenses including: (i) purchases and related costs, (ii) field operating costs and (iii) segment general and administrative expenses, plus (b) our proportionate share of the depreciation and amortization expense (including write-downs related to cancelled projects and impairments) of unconsolidated entities, further adjusted (c) for certain selected items including (i) gains and losses on derivative instruments that are related to underlying activities in another period (or the reversal of such adjustments from a prior period), gains and losses on derivatives that are either related to investing activities (such as the purchase of linefill) or purchases of long-term inventory, and inventory valuation adjustments, as applicable, (ii) long-term inventory costing adjustments, (iii) charges for obligations that are expected to be settled with the issuance of equity instruments, (iv) amounts related to deficiencies associated with minimum volume commitments, net of the applicable amounts subsequently recognized into revenue and (v) other items that our CODM believes are integral to understanding our core segment operating performance and (d) to exclude the portion of all preceding items that is attributable to noncontrolling interests ("Segment amounts attributable to noncontrolling interests").

Our CODM uses Segment Adjusted EBITDA to evaluate the performance of each segment, including analyzing actual results compared to budget and guidance, to assess investment opportunities and to optimize and align assets to maximize returns to stakeholders.

Segment Adjusted EBITDA excludes depreciation and amortization. As an MLP, we make quarterly distributions of our "available cash" (as defined in our partnership agreement) to our unitholders. We look at each period's earnings before non-cash depreciation and amortization as an important measure of segment performance. The exclusion of depreciation and amortization expense could be viewed as limiting the usefulness of Segment Adjusted EBITDA as a performance measure because it does not account in current periods for the implied reduction in value of our capital assets, such as pipelines and facilities, caused by age-related decline and wear and tear. We compensate for this limitation by recognizing that depreciation and amortization are largely offset by repair and maintenance investments, which act to partially offset the aging and wear and tear in the value of our principal fixed assets. These maintenance investments are a component of field operating costs included in Segment Adjusted EBITDA or in maintenance capital, depending on the nature of the cost. Capital expenditures made to expand the existing operating and/or earnings capacity of our assets are classified as investment capital. Capital expenditures made to replace and/or refurbish partially or fully depreciated assets in order to maintain the operating and/or earnings capacity of our existing assets are classified as maintenance capital, which is deducted in determining "available cash." Maintenance capital is reviewed by our CODM on a segment basis. Repair and maintenance expenditures incurred in order to maintain the day to day operation of our existing assets are charged to expense as incurred. Assets are not reviewed by our CODM on a segmented basis; therefore, such information is not presented.

**NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

<sup>(4)</sup> 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, we identify differences in the timing of earnings from the derivative instruments and the underlying transactions and exclude the related gains and losses in determining Segment Adjusted EBITDA such that the earnings from the derivative instruments and the underlying transactions impact Segment Adjusted EBITDA in the same period. In addition, we exclude gains and losses on derivatives that are related to (i) investing activities, such as the purchase of linefill, and (ii) purchases of long-term inventory. We also exclude the impact of corresponding inventory valuation adjustments, as applicable.

<sup>(5)</sup> We carry crude oil and NGL inventory that is 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 exclude the impact of changes in the average cost of the long-term inventory (that result from fluctuations in market prices) and write-downs of such inventory that result from price declines from Segment Adjusted EBITDA.

<sup>(6)</sup> We, and certain of our equity method investees, 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 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 or equity earnings, as a selected item impacting comparability. Our CODM views the inclusion of the contractually committed revenues associated with that period as meaningful to Segment Adjusted EBITDA 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.

<sup>(7)</sup> Our total equity-indexed compensation expense includes expense associated with awards that will be settled in units and awards that will be settled in cash. The awards that will be settled in units are included in our diluted net income per unit calculation when the applicable performance criteria have been met. We exclude compensation expense associated with these awards in determining Segment Adjusted EBITDA as the dilutive impact of the outstanding awards is included in our diluted net income per unit calculation, as applicable. The portion of compensation expense associated with awards that will be settled in cash is not excluded in determining Segment Adjusted EBITDA. See Note 17 to our Consolidated Financial Statements included in Part IV of our 2024 Annual Report on Form 10-K for a discussion regarding our equity-indexed compensation plans.

<sup>(8)</sup> During the periods presented, there were fluctuations in the value of CAD to USD, resulting in the realization of foreign exchange gains and losses on the settlement of foreign currency transactions as well as the revaluation of monetary assets and liabilities denominated in a foreign currency. These gains and losses are not integral to our core operating performance and were therefore excluded in determining Segment Adjusted EBITDA.

<sup>(9)</sup> Primarily related to acquisitions completed during the first nine months of 2025. See Note 12 for information regarding these transactions.

<sup>(10)</sup> Reflects amounts attributable to noncontrolling interests in the Permian JV, Cactus II and Red River.

<sup>(11)</sup> Investment capital and acquisition capital expenditures, including investments in unconsolidated entities.

<sup>(12)</sup> These amounts combined represent total capital expenditures.

<sup>(13)</sup> Includes costs recognized during the period related to the Line 901 incident that occurred in May 2015, net of amounts we believe are probable of recovery from insurance. See Note 10 for additional information regarding the Line 901 incident.

**Note 12*—* Acquisitions**

***Ironwood Midstream***

*Ironwood Midstream*. On January 31, 2025, we acquired Ironwood Midstream Energy Partners II, LLC ("Ironwood Midstream"), which owns a gathering system in the Eagle Ford Basin, for approximately $481 million in cash from EnCap Flatrock Midstream. The Ironwood Midstream acquisition is accounted for in our Crude Oil segment. In January 2025, in a separate transaction, we also repurchased from EnCap Flatrock Midstream, a portion of our outstanding Series A preferred units. EnCap Flatrock Midstream is affiliated with EnCap Investments, L.P., an entity that is associated with a member of the board of directors of PAGP GP. See Note 7 for additional information.

The Ironwood Midstream acquisition was accounted for as a business combination using the acquisition method of accounting. In accordance with applicable accounting guidance, the fair value of the assets acquired and liabilities assumed following the acquisition was utilized as the consideration transferred for the purchase price allocation. The determination of the fair value of the assets and liabilities assumed was estimated in accordance with applicable accounting guidance. The analysis was performed based on estimates that are reflective of market participant assumptions. The following table reflects our preliminary determination of the fair value of the Ironwood Midstream acquisition assets and liabilities (in millions):

---

| | | |
|:---|:---|:---|
| **Identifiable Assets Acquired and Liabilities Assumed:** | **Estimated Useful Lives <br>(in years)** | **Recognized Amount** |
| Property and equipment | 3-30 | $435 |

**PLAINS ALL AMERICAN PIPELINE, L.P. AND SUBSIDIARIES**

**NOTES TO THE UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

The fair value of the tangible asset is a Level 3 measurement in the fair value hierarchy and was determined using a cost approach for tangible assets, which was based on costs incurred on similar recent construction projects, and a market approach for rights-of-way. A Level 3 measurement is one for which there are no observable market inputs. The fair value of the intangible assets is also a Level 3 measurement in the fair value hierarchy and was determined by applying a discounted cash flow approach. Such approach utilized a discount rate of 18%, based on our estimate of the risk that a theoretical market participant would assign to the intangible asset. The projection of future crude oil volumes transported and the estimated tariff rates for transportation were also key assumptions in the valuation of the intangible assets. Projected future volumes and estimated tariff rates were based on current contracts in place with assumptions for forecasted rate increases and contract renewals.

The fair value of intangible asset is comprised of customer relationships that will be amortized over their useful lives, which have a remaining weighted average life of approximately 16 years. The value assigned to such intangible asset will be amortized to earnings under the declining balance method of amortization. Amortization expense was approximately $1 million and $3 million during the three and nine months ended September 30, 2025, respectively, and the future amortization expense for the remainder of 2025 through 2029 is estimated as follows (in millions):

---

| | |
|:---|:---|
| Remainder of 2025 | $1.0 |
| 2026 | $5.0 |
| 2027 | $4.0 |
| 2028 | $3.0 |
| 2029 | $3.0 |

Pro forma financial information assuming the acquisition had occurred as of the beginning of the calendar year prior to the year of the acquisition, as well as the revenues and earnings generated during the period since the acquisition date, were not material for disclosure purposes.

***Other Acquisitions***

*Medallion Midstream*. In January 2025, we acquired EMG Medallion 2 Holdings, LLC and its subsidiaries, which own a crude oil gathering and transportation business in the Delaware Basin, for $163 million (approximately $106 million net to our 65% interest in the Permian JV), subject to certain adjustments. A cash deposit of approximately $16 million was paid upon signing in December 2024. The Medallion Midstream acquisition is accounted for in our Crude Oil segment. EMG Medallion 2 Holdings, LLC was a portfolio company of The Energy & Minerals Group ("EMG"), which is associated with a member of the board of directors of PAGP GP.

*Cheyenne Pipeline*. In February 2025, through a non-monetary transaction, we acquired the remaining 50% interest in Cheyenne Pipeline LLC ("Cheyenne") in exchange for the termination of certain obligations. The transaction resulted in a net gain of approximately $31 million, which represents the difference between the fair value of the entity and the historical book value of our investment. This gain is reflected in "Gain on investments in unconsolidated entities, net" on our Condensed Consolidated Statement of Operations. Prior to this transaction, our 50% interest in Cheyenne was accounted for as an equity method investment, reported in our Crude Oil segment.

*Black Knight Midstream.* During the second quarter of 2025, we acquired Black Knight Midstream, LLC ("Black Knight Midstream"), which owns a crude oil gathering business in the Permian Basin, for $59 million (approximately $38 million net to our 65% interest in the Permian JV), subject to certain adjustments. The Black Knight Midstream assets are accounted for in our Crude Oil segment.

*BridgeTex Pipeline*. In July 2025, we acquired an additional 20% interest in BridgeTex Pipeline Company, LLC ("BridgeTex") for approximately $180 million. As a result of this transaction, we now own a 40% interest in BridgeTex and continue to account for our interest in BridgeTex, which is reported in our Crude Oil segment, as an equity method investment.

*EPIC Pipeline*. On October 31, 2025, we purchased an aggregate 55% equity interest in EPIC Crude Holdings, LP ("EPIC Crude Holdings"), which owns the EPIC Crude Oil Pipeline ("EPIC Pipeline"), from subsidiaries of Diamondback Energy, Inc. and Kinetik Holdings Inc., for approximately $1.57 billion, subject to certain adjustments and inclusive of approximately $600 million of debt assumed. We also agreed to a potential earnout payment of $193 million contingent upon the formal sanctioning before the end of 2027 of one or more expansions of EPIC Pipeline that in the aggregate will increase the capacity of the pipeline to at least 900,000 barrels per day. In a separate transaction, effective November 1, 2025, we acquired the remaining 45% equity interest in EPIC Crude Holdings from a portfolio company of Ares Private Equity funds for approximately $1.33 billion, subject to certain adjustments and inclusive of approximately $500 million of debt assumed. We also agreed to a potential earnout payment to the seller of up to $157 million depending on the timing and amount of incremental expansion capacity up to 300,000 barrels per day in excess of 650,000 barrels per day that is formally sanctioned before the end of 2028.

Subsequent to these two transactions (collectively, the "EPIC acquisition"), we now own 100% of EPIC Crude Holdings and are the operator of record for the EPIC Pipeline, which provides long-haul crude oil takeaway from the Permian and Eagle Ford basins to the Gulf Coast market at Corpus Christi. We believe this acquisition is highly synergistic and strategic to our existing footprint. The EPIC acquisition will be accounted for in our Crude Oil segment.

**Item 2.&nbsp;&nbsp;&nbsp;&nbsp;MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

**Introduction**

The following discussion is intended to provide investors with an understanding of our financial condition and results of our operations and should be read in conjunction with our historical Consolidated Financial Statements and accompanying notes and Management's Discussion and Analysis of Financial Condition and Results of Operations as presented in our 2024 Annual Report on Form 10-K. For more detailed information regarding the basis of presentation for the following financial information, see the Condensed Consolidated Financial Statements and related notes that are contained in Part I, Item 1 of this Quarterly Report on Form 10-Q.

Our discussion and analysis includes the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Executive Summary

**Executive Summary** 

***Company Overview***

Our business model integrates large-scale supply aggregation capabilities with the ownership and operation of critical midstream infrastructure systems that connect major producing regions to key demand centers and export terminals. As one of the largest crude oil midstream service providers in North America, we own an extensive network of pipeline transportation, terminalling, storage and gathering assets in key crude oil producing basins (including the Permian Basin) and transportation corridors and at major market hubs in the United States and Canada. Our assets and the services we provide are primarily focused on crude oil and, to a lesser extent, NGL.

*Pending Sale of Canadian NGL Business*

On June 17, 2025, we entered into a definitive SPA with Keyera, pursuant to which Keyera agreed to acquire all of the issued and outstanding shares of Plains Midstream Canada ULC, our wholly-owned subsidiary that owns substantially all of the Canadian NGL Business. This transaction supports our strategic objective to focus on our core midstream crude oil operations and to reduce exposure to commodity price fluctuations and seasonality. While we will divest the Canadian NGL Business as part of the sale, we will retain substantially all NGL assets in the United States and will also retain all crude oil assets in Canada. This transaction is expected to close in the first quarter of 2026, subject to the satisfaction or waiver of customary closing conditions, including receipt of regulatory approvals. We determined that in conjunction with entering into the SPA, the operations of the Canadian NGL Business meet the criteria for classification as held for sale and for discontinued operations reporting, as the sale will represent a strategic shift that will have a major effect on our operations and financial results. We have applied these changes retrospectively to all periods presented. See Note 1 and Note 2 to our Condensed Consolidated Financial Statements for additional information.

Unless otherwise indicated, the discussion below relates to our continuing operations and excludes amounts related to discontinued operations.

***Overview of Operating Results***

We recognized net income attributable to PAA of $1.093 billion for the nine months ended September 30, 2025 compared to net income attributable to PAA of $736 million for the first nine months of 2024. See the "Results of Operations" section below for discussion of significant drivers of our results from continuing operations.

***Continuing Operations***

The following discussion of our results of operations focuses on our continuing operations.

**Revenues and Purchases**

Fluctuations in our revenues and purchases and related costs are primarily associated with our merchant activities and are generally explained by changes in commodity prices and the impact of gains and losses related to derivative instruments used to manage our commodity price exposure. Because both product sales revenues and purchases and related costs are generally based off of the same pricing indices, the market price of the commodities will not necessarily have an impact on the absolute margins related to those sales and purchases.

A majority of our crude oil sales and purchases are indexed to the prompt month price of the NYMEX Light, Sweet crude oil futures contract ("NYMEX Price"). The following table presents the range of the NYMEX Price over the last two years (in dollars per barrel):

---

| | | | |
|:---|:---|:---|:---|
| | **NYMEX Price** | **NYMEX Price** | **NYMEX Price** |
| | **Low** | **High** | **Average** |
| Three Months Ended September 30, 2025 | $62 | $70 | $65 |
| Three Months Ended September 30, 2024 | $66 | $84 | $75 |
| Nine Months Ended September 30, 2025 | $57 | $80 | $67 |
| Nine Months Ended September 30, 2024 | $66 | $87 | $78 |

---

Product sales revenues (including the impact of derivative mark-to-market valuations) and purchases decreased for the three and nine months ended September 30, 2025 compared to the same periods in 2024 primarily due to lower commodity prices in the 2025 periods, partially offset by higher crude oil sales volumes in the 2025 periods.

Services revenues for the nine months ended September 30, 2025 increased compared to the same period in 2024 primarily due to higher pipeline volumes and tariff escalations, as well as the impact of recently completed acquisitions, partially offset by the impact from lower commodity prices in the 2025 period.

See further discussion of our net revenues (defined as revenues less purchases and related costs) in the "—Analysis of Operating Segments" section below.

**Field Operating Costs**

See discussion of field operating costs in the "—Analysis of Operating Segments" section below.

**General and Administrative Expenses**

The increase in general and administrative expenses for the nine months ended September 30, 2025 compared to the same periods in 2024 was primarily due to transaction costs associated with our recent acquisitions, partially offset by lower information systems costs due to the completion of certain systems conversion and integration work, which was also the primarily driver of the decrease in general and administrative expenses for the comparative three-month period.

**Depreciation and Amortization**

The increase in depreciation and amortization for the nine months ended September 30, 2025 compared to the same periods in 2024 was largely driven by acquisitions.

------

<u>[**Table of Contents**](#i29a905161dd64cdb968dbc606bd49e76_7)</u> 

**Gains/Losses on Asset Sales, Net**

In connection with the pending sale of the Canadian NGL Business, we entered into a deal-contingent forward currency instrument to hedge the currency exchange risk associated with the sale in CAD. The 2025 periods were impacted by the mark-to-market of this instrument. See Note 8 to our Condensed Consolidated Financial Statements for additional information regarding this instrument and our derivatives and hedging activities. See Note 1 to our Condensed Consolidated Financial Statements for additional information regarding the pending sale of the Canadian NGL Business.

**Equity Earnings**

See discussion of Equity earnings in unconsolidated entities in the "—Analysis of Operating Segments" section below.

**Gain on Investments in Unconsolidated Entities, Net**

We recognized a net gain of $31 million related to our acquisition of the remaining 50% interest in Cheyenne in the first quarter of 2025. See Note 12 to our Condensed Consolidated Financial Statements for additional information regarding this transaction.

**Interest Expense, Net and Other Income, Net**

For the three and nine months ended September 30, 2025 and 2024, "Interest expense, net" and "Other income, net" each include interest expense and interest income associated with promissory notes payable and receivable by and among us and certain Plains entities. These amounts are excluded from our non-GAAP performance measures Adjusted EBITDA and Implied DCF. As such, the interest expense and interest income associated with these notes are presented on a net basis in the reconciliation of these metrics to Net Income. See the "—Non-GAAP Financial Measures" section below.

The following table summarizes the components impacting Interest expense, net (in millions):

---

| | | | | |
|:---|:---|:---|:---|:---|
| | **Three Months Ended<br>September 30,** | **Three Months Ended<br>September 30,** | **Nine Months Ended<br>September 30,** | **Nine Months Ended<br>September 30,** |
| | **2025** | **2024** | **2025** | **2024** |
| Interest expense on third-party borrowings <sup>(1)</sup> | $116 | $99 | $339 | $294 |
| Interest expense on related party promissory notes <sup>(2)</sup> | 23 | 16 | 65 | 31 |
| Capitalized interest | (4) | (2) | (9) | (7) |
|  | $135 | $113 | $395 | $318 |

---

<sup>(1)</sup> The increase in interest expense for the three-month 2025 period compared to the same period in 2024 was primarily driven by the issuances of (i) $1.0 billion, 5.95% senior notes in January 2025 and (ii) $700 million, 4.70% senior notes and $550 million, 5.60% senior notes in September 2025, partially offset by the repayment of (iii) $750 million, 3.60% senior notes in November 2024. The increase for the nine-month comparative period was further impacted by the issuance of $650 million, 5.70% senior notes in June 2024. See Note 6 to our Condensed Consolidated Financial Statements for additional information regarding our senior notes.

<sup>(2)</sup> Represents interest expense associated with promissory notes by and among us and certain Plains entities, as described above.

<sup>(1)</sup> Represents interest income associated with promissory notes by and among us and certain Plains entities, as described above.

<sup>(2)</sup> Primarily includes interest income from other sources and gains and losses on foreign revaluation related to the impact from the change in the CAD to USD exchange rate on the portion of our intercompany net investment that is not long-term in nature.

**Income Tax Expense**

The net favorable income tax variance for the nine months ended September 30, 2025 compared to the same period in 2024 was primarily due to the impact of (i) lower income tax expense in 2025 associated with Canadian withholding tax on dividends from our Canadian entities to other Plains entities, partially offset by (ii) higher year-over-year income within our Canadian operations as impacted by fluctuations of derivative mark-to-market valuations.

***Non-GAAP Financial Measures***

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 and to assess the amount of cash that is available for distributions, debt repayments, common equity repurchases and other general partnership purposes. The primary additional measures used by management are Adjusted EBITDA, Adjusted EBITDA attributable to PAA, Implied distributable cash flow ("DCF"), Adjusted Free Cash Flow and Adjusted Free Cash Flow after Distributions.

Our definition and calculation of certain non-GAAP financial measures may not be comparable to similarly-titled measures of other companies. Adjusted EBITDA, Adjusted EBITDA attributable to PAA and Implied DCF are reconciled to Net Income, and Adjusted Free Cash Flow and Adjusted Free Cash Flow after Distributions are reconciled to Net Cash Provided by Operating Activities, the most directly comparable measures as reported in accordance with GAAP, and should be viewed in addition to, and not in lieu of, our Condensed Consolidated Financial Statements and accompanying notes. See "—Liquidity and Capital Resources—Non-GAAP Financial Liquidity Measures" for additional information regarding Adjusted Free Cash Flow and Adjusted Free Cash Flow after Distributions.

**Non-GAAP Financial Performance Measures**

Adjusted EBITDA is defined as earnings from continuing operations and discontinued operations before (i) interest expense, (ii) income tax (expense)/benefit from continuing operations and discontinued operations, (iii) depreciation and amortization (including our proportionate share of depreciation and amortization, including write-downs related to cancelled projects and impairments, of unconsolidated entities) from continuing operations and discontinued operations, (iv) gains and losses on asset sales, asset impairments and other, net from continuing operations and discontinued operations, (v) gains on investments in unconsolidated entities, net and (vi) interest income on promissory notes by and among us and certain Plains entities, and (vii) adjusted for certain selected items impacting comparability. Adjusted EBITDA attributable to PAA excludes the portion of Adjusted EBITDA that is attributable to noncontrolling interests.

Management believes that the presentation of Adjusted EBITDA, Adjusted EBITDA attributable to PAA and Implied DCF 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 operating performance and ability to fund distributions to our unitholders through cash generated by our operations, (ii) provide investors with the same financial analytical framework upon which management bases financial, operational, compensation and planning/budgeting decisions and (iii) present measures that investors, rating agencies and debt holders have indicated are useful in assessing us and our results of operations. These non-GAAP financial performance measures may exclude, for example, (i) charges for obligations that are expected to be settled with the issuance of equity instruments, (ii) gains and losses on derivative instruments that are related to underlying activities in another period (or the reversal of such adjustments from a prior period), gains and losses on derivatives that are either related to investing activities (such as the purchase of linefill) or purchases of long-term inventory, and inventory valuation adjustments, as applicable, (iii) long-term inventory costing adjustments, (iv) items that are not indicative of our operating results and/or (v) other items that we believe should be excluded in understanding our 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 "Other current liabilities" in our Condensed Consolidated Financial Statements. We also adjust for amounts billed by our equity method investees related to deficiencies under minimum volume commitments. Such amounts are presented net of applicable amounts subsequently recognized into revenue. We have defined all such items as "selected items impacting comparability." 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, divestitures, investment capital projects and numerous other factors as discussed, as applicable, in "—Analysis of Operating Segments."

*Discontinued Operations.* Management believes that the presentation of certain Non-GAAP financial performance measures, such as Adjusted EBITDA, Adjusted EBITDA attributable to PAA, Implied DCF, and certain Non-GAAP financial liquidity measures, such as Adjusted Free Cash Flow and Adjusted Free Cash Flow (Excluding Changes in Assets & Liabilities), on a consolidated basis (e.g., the aggregate of continuing operations and discontinued operations) provides more relevant and useful information regarding our performance and results of operations than presenting such metrics only on a continuing operations or discontinued operations basis. In addition, as the potential sale of the Canadian NGL Business is not anticipated to close until the first quarter of 2026, management continues to view the Canadian NGL Business as a component of our overall company performance and ability to fund distributions to our unitholders in the near term.

***Analysis of Operating Segments***

We manage our operations through two operating segments: Crude Oil and NGL. Our CODM (our Chief Executive Officer) evaluates segment performance based on measures including Segment Adjusted EBITDA. See Note 11 to our Condensed Consolidated Financial Statements for our definition of Segment Adjusted EBITDA and a reconciliation of Segment Adjusted EBITDA to Income from Continuing Operations, Net of Tax. See Note 19 to our Consolidated Financial Statements included in Part IV of our 2024 Annual Report on Form 10-K for our definition of maintenance capital.

**Crude Oil Segment**

Our Crude Oil segment operations generally consist of gathering and transporting crude oil using pipelines (including gathering systems), trucks and, at times, on barges or railcars, in addition to providing terminalling, storage and other related services utilizing our integrated assets across the United States and Canada. Our assets provide services to third parties as well as to our merchant activities. Our merchant activities include the purchase of crude oil supply and the movement of this supply on our assets or third-party assets to sales locations, including our terminals, third-party connecting carriers, regional hubs or to refineries. Our merchant activities are governed by our risk management policies.

Our Crude Oil segment generates revenue through a combination of tariffs, pipeline capacity agreements and other transportation fees, month-to-month and multi-year storage and terminalling agreements and the sale of gathered and bulk-purchased crude oil. Tariffs and other fees on our pipeline systems are typically based on volumes transported and vary by receipt point and delivery point. Fees for our terminalling and storage services are based on capacity leases and throughput volumes. Generally, results from our merchant activities are impacted by (i) increases or decreases in our lease gathering crude oil purchases volumes and (ii) volatility in commodity price differentials, particularly grade and location differentials, as well as time spreads. The segment results also include the direct fixed and variable field costs of operating the crude oil assets, as well as an allocation of indirect operating and general and administrative costs.

*Segment Adjusted EBITDA*

Crude Oil Segment Adjusted EBITDA for the three and nine months ended September 30, 2025 increased versus comparable results for the three and nine months ended September 30, 2024. The benefit to the 2025 period from higher tariff volumes on our pipelines, tariff escalations and contributions from recently completed acquisitions was largely offset by fewer market-based opportunities.

The following is a more detailed discussion of the significant factors impacting Segment Adjusted EBITDA for the three and nine months ended September 30, 2025 compared to the same periods in 2024.

*Net Revenues and Equity Earnings.* Our results were favorably impacted by (i) volume growth across our pipeline systems largely driven by increased production in the Permian Basin region, (ii) contributions from recently completed acquisitions in the Permian Basin and South Texas regions and (iii) the benefit of tariff escalations. These favorable impacts were partially offset by (iv) fewer market-based opportunities, (v) lower commodity prices, which resulted in lower revenues from pipeline loss allowance in the 2025 periods, and (vi) the impact from certain Permian long-haul contract rates resetting to market in the third quarter of 2025.

*Field Operating Costs.* The decrease in field operating costs for the three and nine months ended September 30, 2025 compared to the same periods in 2024 was primarily due to the recognition in the third quarter of 2024 of costs associated with settlements related to the Line 901 incident that occurred in May 2015 (which impact field operating costs, but are excluded from Segment Adjusted EBITDA, and thus are reflected as an "Adjustment" in the table above). This was partially offset by higher expenses resulting from acquisitions and higher volumes in the 2025 periods. In addition, the nine-month period was further impacted by higher expenses associated with (i) environmental remediation costs and (ii) property taxes.

*Maintenance Capital*

The decrease in maintenance capital spending for the three and nine months ended September 30, 2025 compared to the same periods in 2024 was primarily due to lower costs resulting from timing of certain pipeline integrity activities.

<u>[**Table of Contents**](#i29a905161dd64cdb968dbc606bd49e76_7)</u> 

**NGL Segment**

Our NGL segment operations involve NGL storage and terminalling from our four NGL assets located in the United States, namely our Bumstead, Shafter, San Pedro and Tampa facilities. Our NGL segment revenues are primarily derived from (i) providing storage and/or terminalling services at these facilities to third-party customers for a fee and (ii) the transport, storage and sale of specification NGL products. The segment results also include the direct fixed and variable field costs of operating our four NGL facilities, as well as an allocation of indirect operating costs and general and administrative expenses.

The following table sets forth our operating results from our NGL segment:

<sup>(1)</sup> Revenues and costs and expenses include intersegment amounts.

<sup>(2)</sup> Field operating costs and segment general and administrative expenses include certain costs that are part of the overhead of continuing operations.

<sup>(3)</sup> 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.

*Segment Adjusted EBITDA*

The Segment Adjusted EBITDA loss for all periods presented is largely driven by costs that are part of the overhead of our NGL activities and are included in continuing operations as they are not related to contracts or arrangements that will be included in the sale of the Canadian NGL Business. These costs include information technology, insurance and other shared services costs.

**Liquidity and Capital Resources**

***General***

Our primary sources of liquidity are (i) cash flow from operating activities and (ii) borrowings under our credit facilities or commercial paper program. In addition, we may supplement these primary sources of liquidity with proceeds from asset sales, and in the past have utilized funds received from sales of equity and debt securities. Our primary cash requirements include, but are not limited to, (i) ordinary course of business uses, such as the payment of amounts related to the purchase of crude oil, NGL and other products, payment of other expenses and interest payments on outstanding debt, (ii) investment and maintenance capital activities, (iii) acquisitions of assets or businesses, (iv) repayment of principal on our long-term debt and (v) distributions to our unitholders and noncontrolling interests. In addition, we may use cash for repurchases of common equity. We generally expect to fund our short-term cash requirements through cash flow generated from operating activities and/or borrowings under our credit facilities or commercial paper program. In addition, we generally expect to fund our long-term needs, such as those resulting from investment capital activities, acquisitions or refinancing our long-term debt, through a variety of sources, which may include any or a combination of the sources listed above.

Usage of our credit facilities, and, in turn, our commercial paper program, is subject to ongoing compliance with covenants. The credit agreements for our revolving credit facilities (which impact our ability to access our commercial paper program because they provide the financial backstop that supports our short-term credit ratings) and the indentures governing our senior notes contain cross-default provisions. A default under our credit agreements or indentures would permit the lenders to accelerate the maturity of the outstanding debt. As long as we are in compliance with the provisions in our credit agreements, our ability to make distributions of available cash is not restricted. We were in compliance with the covenants contained in our credit agreements and indentures as of September 30, 2025.

We believe that we have, and will continue to have, the ability to access our commercial paper program and credit facilities, which we use to meet our short-term cash needs. We believe that our financial position remains strong and we have sufficient liquid assets, cash flow from operating activities and borrowing capacity under our credit agreements to meet our financial commitments, debt service obligations, contingencies and anticipated capital expenditures. We are, however, subject to business and operational risks that could adversely affect our cash flow, including extended disruptions in the financial markets and/or energy price volatility resulting from current macroeconomic and geopolitical conditions, including actions by the Organization of Petroleum Exporting Countries (OPEC). A prolonged material decrease in our cash flows would likely produce an adverse effect on our borrowing capacity and cost of borrowing. Our borrowing capacity and borrowing costs are also impacted by our credit rating. See Item 1A. "Risk Factors" included in our 2024 Annual Report on Form 10-K for further discussion regarding risks that may impact our liquidity and capital resources.

***Non-GAAP Financial Liquidity Measures***

Management uses the non-GAAP financial liquidity measures Adjusted Free Cash Flow and Adjusted Free Cash Flow after Distributions to assess the amount of cash that is available for distributions, debt repayments, common equity repurchases and other general partnership purposes. Adjusted Free Cash Flow is defined as Net cash provided by operating activities, less Net cash provided by/(used in) investing activities, which primarily includes acquisition, investment and maintenance capital expenditures, investments in unconsolidated entities and related party notes and the impact from the purchase and sale of linefill, net of proceeds from the sales of assets and further impacted by distributions to and contributions from noncontrolling interests and proceeds from the issuance of related party notes. Adjusted Free Cash Flow is further reduced by cash distributions paid to our preferred and common unitholders to arrive at Adjusted Free Cash Flow after Distributions. Also see "Results of Operations–Non-GAAP Financial Measures" above for more information about our non-GAAP measures.

***Cash Flow from Operating Activities***

For a comprehensive discussion of the primary drivers of cash flow from operating activities, including the impact of varying market conditions and the timing of settlement of our derivatives, see Item 7. "Liquidity and Capital Resources—Cash Flow from Operating Activities" included in our 2024 Annual Report on Form 10-K.

Net cash provided by operating activities from continuing operations for the first nine months of 2025 and 2024 was $1.836 billion and $1.597 billion, respectively, and primarily resulted from earnings from our operations.

<u>[**Table of Contents**](#i29a905161dd64cdb968dbc606bd49e76_7)</u> 

*2025 Investment and Maintenance Capital.* Total investment capital for the year ending December 31, 2025 is projected to be approximately $600 million ($490 million net to our interest), which includes approximately $110 million related to discontinued operations. Approximately half of our projected investment capital expenditures are expected to be invested in the Permian JV assets. Additionally, maintenance capital for 2025 is projected to be approximately $230 million ($215 million net to our interest), which includes approximately $70 million related to discontinued operations.

**Ongoing Activities Related to Strategic Transactions** 

We are continuously engaged in the evaluation of potential transactions that support our current business strategy. In the past, such transactions have included the acquisition of assets that complement our existing footprint, the sale of non-core assets, the sale of partial interests in assets to strategic joint venture partners, and large investment capital projects. With respect to a potential acquisition or divestiture, we may conduct an auction process or participate in an auction process conducted by a third-party or we may negotiate a transaction with one or a limited number of potential sellers (in the case of an acquisition) or buyers (in the case of a divestiture). Such transactions could have a material effect on our financial condition and results of operations.

We typically do not announce a transaction until after we have executed a definitive agreement. In certain cases, in order to protect our business interests or for other reasons, we may defer public announcement of a transaction until closing or a later date. Past experience has demonstrated that discussions and negotiations regarding a potential transaction can advance or terminate in a short period of time. Moreover, the closing of any transaction for which we have entered into a definitive agreement may be subject to customary and other closing conditions, which may not ultimately be satisfied or waived. Accordingly, we can give no assurance that our current or future efforts with respect to any such transactions will be successful, and we can provide no assurance that our financial expectations with respect to such transactions will ultimately be realized. See Item 1A. "Risk Factors—Risks Related to Our Business—Acquisitions and divestitures involve risks that may adversely affect our business" included in our 2024 Annual Report on Form 10-K.

**Related Party Promissory Notes**

In February 2025, promissory notes with a face value of CAD$473 million (approximately $330 million) were issued by and among us and certain Plains entities. The cash outflow associated with our investment in promissory notes issued by PAGP to us has an equal and offsetting cash inflow associated with proceeds from the issuance by our consolidated subsidiary of promissory notes to PAGP for the same face value amount, which is included as a component of financing activities. See Note 9 to our Condensed Consolidated Financial Statements for additional information on our related party notes.

***Financing Activities***

Our financing activities primarily relate to funding investment capital projects, acquisitions and refinancing of our debt maturities, as well as short-term working capital (including borrowings for NYMEX and ICE margin deposits) and hedged inventory borrowings related to our NGL business and contango market activities, and the payment of distributions to our unitholders and noncontrolling interests.

**Borrowings and Repayments Under Credit Agreements**

During the nine months ended September 30, 2025, we had net repayments under our commercial paper program of $393 million. The net repayments resulted primarily from cash flow from operating activities and proceeds from the issuance of $1.25 billion aggregate principal amount of senior notes in September 2025, which offset borrowings during the period related to funding needs for capital investments, inventory purchases and other general partnership purposes.

During the nine months ended September 30, 2024, we had net repayments under our commercial paper program of $433 million. The net repayments resulted primarily from cash flow from operating activities and proceeds from the issuance of $650 million, 5.70% senior notes in June 2024, which offset borrowings during the period related to funding needs for capital investments, inventory purchases and other general partnership purposes.

**Senior Notes**

In January 2025, we completed the offering of $1.0 billion, 5.95% senior notes due June 2035 at a public offering price of 99.761%. Interest payments are due on June 15 and December 15 of each year, commencing on June 15, 2025. We used the net proceeds from this offering of approximately $988 million, after deducting the underwriting discount and offering expenses, to (i) fund the acquisitions completed during the nine months ended September 30, 2025, (ii) fund the repurchase of approximately 12.7 million Series A preferred units in January 2025 and (iii) repay outstanding borrowings under our credit facilities and commercial paper program and for general partnership purposes.

In September 2025, we completed the offering of $1.25 billion aggregate principal amount of senior notes, consisting of $700 million, 4.70% senior notes due January 2031 and $550 million, 5.60% senior notes due January 2036 at a public offering price of 99.865% and 99.798%, respectively. Interest payments on these notes are due on January 15 and July 15 of each year, commencing on January 15, 2026. We used the net proceeds from this offering of approximately $1.2 billion, after deducting the underwriting discount and offering expenses, to (i) redeem on October 3, 2025 the principal amount of our $1.0 billion, 4.65% senior notes due October 2025 and (ii) fund a portion of the purchase price for the EPIC Pipeline acquisition.

See Note 7 and Note 12 to our Condensed Consolidated Financial Statements for additional information regarding our Series A preferred units and our recently completed and pending acquisitions, respectively.

**Common Equity Repurchase Program**

We repurchased 0.5 million common units under the Common Equity Repurchase Program (the "Program") through open market purchases that settled during the nine months ended September 30, 2025, for a total purchase price of $8 million, including commissions and fees. The repurchased common units were canceled immediately upon acquisition, as were the PAGP Class C shares held by us associated with the repurchased common units. There were no repurchases under the Program during the nine months ended September 30, 2024. At September 30, 2025, the remaining available capacity under the Program was $190 million. See Note 11 to our Consolidated Financial Statements included in Part IV of our 2024 Annual Report on Form 10-K for additional information regarding the Program.

**Registration Statements** 

We periodically access the capital markets for both equity and debt financing. We have filed with the SEC a universal shelf registration statement that, subject to effectiveness at the time of use, allows us to issue up to a specified amount of debt or equity securities ("Traditional Shelf"), under which we had approximately $1.1 billion of unsold securities available at September 30, 2025. We did not conduct any offerings under our Traditional Shelf during the nine months ended September 30, 2025. We also have access to a universal shelf registration statement ("WKSI Shelf"), which provides us with the ability to offer and sell an unlimited amount of debt and equity securities, subject to market conditions and our capital needs. The offerings of $1.0 billion, 5.95% senior notes in January 2025, $700 million, 4.70% senior notes and $550 million, 5.60% senior notes in September 2025 were conducted under our WKSI Shelf.

**Series A Preferred Unit Repurchase**

On January 31, 2025, we repurchased approximately 12.7 million units, or 18%, of our outstanding Series A preferred units at the issue price of $26.25 per unit for a purchase price of approximately $333 million, plus accrued and unpaid distributions through January 30, 2025 of approximately $10 million. We used a portion of the net proceeds from our January 2025 senior notes offering to fund this repurchase. See Note 7 to our Condensed Consolidated Financial Statements for more information regarding our Series A preferred units.

**Distributions to Our Unitholders**

*Series A preferred unitholders.* On November 14, 2025, we will pay a quarterly cash distribution of approximately $0.615 per unit to Series A preferred unitholders of record at the close of business on October 31, 2025 for the period from July 1, 2025 through September 30, 2025.

*Series B preferred unitholders.* On November 17, 2025, we will pay a quarterly cash distribution of approximately $21.93 per unit to Series B preferred unitholders of record at the close of business on November 3, 2025 for the period from August 15, 2025 through November 14, 2025.

*Common Unitholders*. On November 14, 2025, we will pay a quarterly cash distribution of $0.38 per common unit ($1.52 per unit on an annualized basis) to common unitholders of record at the close of business on October 31, 2025 for the period from July 1, 2025 through September 30, 2025.

See Note 7 to our Condensed Consolidated Financial Statements for details of distributions paid during or pertaining to the first nine months of 2025, including distributions to our preferred unitholders.

**Distributions to Noncontrolling Interests**

Distributions to noncontrolling interests represent amounts paid on interests in consolidated entities that are not owned by us. As of September 30, 2025, noncontrolling interests in our subsidiaries consisted of (i) a 35% interest in the Permian JV, (ii) a 30% interest in Cactus II and (iii) a 33% interest in Red River. See Note 7 to our Condensed Consolidated Financial Statements for details of distributions paid to noncontrolling interests during the nine months ended September 30, 2025.

**Related Party Promissory Notes**

In February 2025, promissory notes with a face value of CAD$473 million (approximately $330 million) were issued by and among us and certain Plains entities. The cash inflow associated with proceeds from the issuance by our consolidated subsidiary of promissory notes to PAGP has an equal and offsetting cash outflow associated with our investment in promissory notes issued by PAGP to us for the same face value amount, which is included as a component of investing activities. See Note 9 to our Condensed Consolidated Financial Statements for additional information on our related party notes.

***Contingencies***

For a discussion of contingencies that may impact us, see Note 10 to our Condensed Consolidated Financial Statements.

***Commitments***

*Purchase Obligations.* In the ordinary course of doing business, we purchase crude oil from third parties under contracts, the majority of which range in term from thirty-day evergreen to five years, with a limited number of contracts with remaining terms extending up to 10 years. We establish a margin for these purchases by entering into various types of physical and financial sale and exchange transactions through which we seek to maintain a position that is substantially balanced between purchases on the one hand and sales and future delivery obligations on the other. We do not expect to use a significant amount of internal capital to meet these obligations, as the obligations will be funded by corresponding sales to entities that we deem creditworthy or who have provided credit support we consider adequate.

------

<u>[**Table of Contents**](#i29a905161dd64cdb968dbc606bd49e76_7)</u> 

The following table includes our best estimate of the amount and timing of these payments as of September 30, 2025 (in millions):

---

| | | | | | | | |
|:---|:---|:---|:---|:---|:---|:---|:---|
| | **Remainder of 2025** | **2026** | **2027** | **2028** | **2029** | **2030 and Thereafter** | **Total** |
| Crude oil and other purchases <sup>(1)</sup> | $6546 | $20496 | $18425 | $16159 | $15072 | $35624 | $112322 |

---

<sup>(1)</sup> Amounts are primarily based on estimated volumes and market prices based on average activity during September 2025. The actual physical volume purchased and actual settlement prices will vary from the assumptions used in the table. Uncertainties involved in these estimates include levels of production at the wellhead, weather conditions, changes in market prices and other conditions beyond our control.

*EPIC Acquisition.* Through two separate transactions completed in the fourth quarter of 2025, we acquired 100% of the entity that owns the EPIC Pipeline for aggregate consideration of approximately $2.9 billion, inclusive of approximately $1.1 billion of debt assumed. We initially funded the EPIC acquisition by assuming the $1.1 billion of existing debt and funding the $1.8 billion equity portion through a combination of commercial paper and credit facility borrowings and cash on hand. See Note 12 to our Condensed Consolidated Financial Statements for additional information regarding the EPIC acquisition.

*Letters of Credit.* In connection with our merchant activities, we provide certain suppliers with irrevocable standby letters of credit to secure our obligation for the purchase and transportation of crude oil, NGL and natural gas. Our liabilities with respect to these purchase obligations are recorded in accounts payable on our balance sheet in the month the product is purchased. Generally, these letters of credit are issued for periods of up to seventy days and are terminated upon completion of each transaction. Additionally, we issue letters of credit to support insurance programs, derivative transactions, including hedging-related margin obligations, and construction activities. At September 30, 2025 and December 31, 2024, we had outstanding letters of credit of approximately $70 million and $90 million, respectively.

**FORWARD-LOOKING STATEMENTS**

All statements included in this report, other than statements of historical fact, are forward-looking statements, including but not limited to statements incorporating the words "anticipate," "believe," "estimate," "expect," "plan," "intend" and "forecast," as well as similar expressions and statements regarding our business strategy, plans and objectives for future operations. The absence of such words, expressions or statements, however, does not mean that the statements are not forward-looking. Any such forward-looking statements reflect our current views with respect to future events, based on what we believe to be reasonable assumptions. Certain factors could cause actual results or outcomes to differ materially from the results or outcomes anticipated in the forward-looking statements. The most important of these factors include, but are not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• declines in global crude oil demand and/or crude oil prices or other factors that correspondingly lead to a significant reduction of North American crude oil and NGL production (whether due to reduced producer cash flow to fund drilling activities or the inability of producers to access capital, or both, the unavailability of pipeline and/or storage capacity, the shutting-in of production by producers, government-mandated pro-ration orders, or other factors), which in turn could result in significant declines in the actual or expected volume of crude oil and NGL shipped, processed, purchased, stored, fractionated and/or gathered at or through the use of our assets and/or the reduction of the margins we can earn or the commercial opportunities that might otherwise be available to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fluctuations in refinery capacity and other factors affecting demand for various grades of crude oil and NGL and resulting changes in pricing conditions or transportation throughput requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability of, and our ability to consummate, acquisitions, divestitures, joint ventures or other strategic opportunities and realize benefits therefrom, including the Canadian NGL Business divestiture and the EPIC acquisition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the successful operation of joint ventures and joint operating arrangements we enter into from time to time, whether relating to assets operated by us or by third parties, and the successful integration and future performance of acquired assets or businesses, including the EPIC acquisition;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• environmental liabilities, litigation or other events that are not covered by an indemnity, insurance or existing reserves;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• negative societal sentiment regarding the hydrocarbon energy industry and the continued development and consumption of hydrocarbons, which could influence consumer preferences and governmental or regulatory actions that adversely impact our business;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the occurrence of a natural disaster, catastrophe, terrorist attack (including eco-terrorist attacks) or other event that materially impacts our operations, including cyber or other attacks on our or our service providers' electronic and computer systems;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• weather interference with business operations or project construction, including the impact of extreme weather events or conditions (including hurricanes, floods, wildfires and drought);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• negative impacts on production levels in the Permian Basin or elsewhere due to issues associated with (or laws, rules or regulations relating to) hydraulic fracturing and related activities (including wastewater injection or disposal), including earthquakes, subsidence, expansion or other issues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the pace of development of natural gas or other infrastructure and its impact on expected crude oil production growth in the Permian Basin;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the refusal or inability of our customers or counterparties to perform their obligations under their contracts with us (including commercial contracts, asset sale agreements and other agreements), whether justified or not and whether due to financial constraints (such as reduced creditworthiness, liquidity issues or insolvency), market constraints, legal constraints (including governmental orders or guidance), the exercise of contractual or common law rights that allegedly excuse their performance (such as force majeure or similar claims) or other factors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• loss of key personnel and inability to attract and retain new talent;

**Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

We are exposed to various market risks, including commodity price risk, interest rate risk and currency exchange rate risk. We use various derivative instruments to manage such risks and, in certain circumstances, to realize incremental margin during volatile market conditions. Our risk management policies and procedures are designed to help ensure that our hedging activities address our risks by monitoring our exchange-cleared and over-the-counter positions, as well as physical volumes, grades, locations, delivery schedules and storage capacity. We have a risk management function that has direct responsibility and authority for our risk policies, related controls around commercial activities and certain aspects of corporate risk management. Our risk management function also approves all new risk management strategies through a formal process. The following discussion addresses each category of risk.

**Commodity Price Risk**

We use derivative instruments to hedge price risk associated with the following commodities:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• <u>Crude oil</u>*

We utilize crude oil derivatives to hedge commodity price risk inherent in our pipeline, terminalling and merchant activities. Our objectives for these derivatives include hedging changes in inventory positions associated with our lease gathering activities, anticipated purchases and sales, stored inventory and basis differentials. We manage these exposures with various instruments including futures, forwards, swaps and options.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• <u>Power</u>*

We utilize power derivatives to hedge anticipated operational requirements related to our crude oil pipelines. We manage these exposures with various instruments including futures, swaps and options.

See Note 8 to our Condensed Consolidated Financial Statements for further discussion regarding our hedging strategies and objectives.

The fair value of our commodity derivatives and the change in fair value as of September 30, 2025 that would be expected from a 10% price increase or decrease is shown in the table below (in millions):

---

| | | | |
|:---|:---|:---|:---|
| | **Fair Value** | **Effect of 10%<br>Price Increase** | **Effect of 10%<br>Price Decrease** |
| Crude oil | $1 | $27 | $(27) |
| Power | (5) | $2 | $(2) |
| &nbsp;&nbsp;&nbsp;Total fair value | $(4) |  |  |

---

The fair values presented in the table above reflect the sensitivity of the derivative instruments only and do not include the effect of the underlying hedged commodity. Price-risk sensitivities were calculated by assuming an across-the-board 10% increase or decrease in price regardless of term or historical relationships between the contractual price of the instruments and the underlying commodity price. In the event of an actual 10% change in near-term commodity prices, the fair value of our derivative portfolio would typically change less than that shown in the table as changes in near-term prices are not typically mirrored in delivery months further out.

**Interest Rate Risk**

*Debt*. Our use of variable rate debt and any forecasted issuances of fixed rate debt expose us to interest rate risk. Therefore, from time to time, we use interest rate derivatives to hedge interest rate risk associated with anticipated interest payments and, in certain cases, outstanding debt instruments. All of our senior notes are fixed rate notes and thus are not subject to interest rate risk. We did not have any variable rate debt outstanding at September 30, 2025. The average interest rate on variable rate debt that was outstanding during the nine months ended September 30, 2025 was approximately 4.7%, based upon rates in effect during such period. The fair value of our interest rate derivatives was a net asset of $29 million as of September 30, 2025. A 10% increase in the forward SOFR curve as of September 30, 2025 would have resulted in an increase of $13 million to the fair value of our interest rate derivatives. A 10% decrease in the forward SOFR curve as of September 30, 2025 would have resulted in a decrease of $13 million to the fair value of our interest rate derivatives. See Note 8 to our Condensed Consolidated Financial Statements for a discussion of our interest rate risk hedging activities.

*Series B Preferred Units*. Distributions on the Series B preferred units accumulate and are payable quarterly in arrears on the 15th day of February, May, August and November. Distributions on the Series B preferred units accumulate based on the applicable three-month SOFR, plus certain adjustments. Based upon the Series B preferred units outstanding at September 30, 2025 and the liquidation preference of $1,000 per unit, a change of 100 basis points in interest rates would increase or decrease the annual distributions on the Series B preferred units by approximately $8 million. See Note 11 to our Consolidated Financial Statements included in Part IV of our 2024 Annual Report on Form 10-K for additional information regarding our Series B preferred unit distributions.

**Currency Exchange Rate Risk**

We use foreign currency derivatives to hedge foreign currency exchange rate risk associated with our exposure to fluctuations in the USD-to-CAD exchange rate. The fair value of our foreign currency derivatives was an asset of $41 million as of September 30, 2025. A 10% increase in the exchange rate (USD-to-CAD) would have resulted in an increase of $325 million to the fair value of our foreign currency derivatives. A 10% decrease in the exchange rate (USD-to-CAD) would have resulted in a decrease of $325 million to the fair value of our foreign currency derivatives. See Note 8 to our Condensed Consolidated Financial Statements for additional information regarding our currency exchange rate risk hedging.

**Item 4. CONTROLS AND PROCEDURES**

***Disclosure Controls and Procedures***

We maintain written disclosure controls and procedures, which we refer to as our "DCP." Our DCP is designed to ensure that information required to be disclosed by us in reports that we file under the Securities Exchange Act of 1934 (the "Exchange Act") is (i) recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and (ii) accumulated and communicated to management, including our Chief Executive Officer and Chief Financial Officer, to allow for timely decisions regarding required disclosure.

Applicable SEC rules require an evaluation of the effectiveness of our DCP. Management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of our DCP as of September 30, 2025, the end of the period covered by this report, and, based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our DCP is effective.

***Changes in Internal Control over Financial Reporting***

We substantially completed the implementation of our new Enterprise Resource Planning ("ERP") system during the quarter ended September 30, 2025. The implementation of our ERP system (i) resulted in changes to controls that are reliant upon system configurations, integrations and outputs, and (ii) is expected to, among other things, improve user access security and enable convergence of accounting, back office and reporting processes and activities. Except for the implementation of our new ERP system and corresponding changes to controls reliant upon system configurations, integrations and outputs, there was no change in our internal control over financial reporting that occurred during the third quarter of 2025 that materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

**Item 1A. RISK FACTORS**

For a discussion of our risk factors, see Item 1A. of our 2024 Annual Report on Form 10-K. Those risks and uncertainties are not the only ones facing us and there may be additional matters of which we are unaware or that we currently consider immaterial. All of those risks and uncertainties could adversely affect our business, financial condition and/or results of operations.

**Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS**

*Sales of Unregistered Securities*

The Omnibus Agreement, entered into as part of the Simplification Transactions, which closed on November 15, 2016, provides for the mechanics by which (i) the total number of PAGP's outstanding Class A shares will equal the number of AAP units held by PAGP, and (ii) the total number of our common units held by AAP will equal the sum of the number of outstanding Class A units of AAP ("AAP units") and the number of AAP units that are issuable to the holders of vested and earned Class B units of AAP ("AAP Management Units"). As such, we are obligated to issue common units to AAP in connection with PAGP's issuance of Class A shares upon PAGP LTIP award vestings. During the three months ended September 30, 2025, we issued 144,500 common units to AAP in connection with PAGP LTIP award vestings. This issuance was exempt from the registration requirements of the Securities Act of 1933, as amended, pursuant to Section 4(a)(2) thereof.

*Issuer Purchases of Equity Securities*

None.

&nbsp;&nbsp;&nbsp;&nbsp;

**Item 3. DEFAULTS UPON SENIOR SECURITIES**

None.

**Item 4. MINE SAFETY DISCLOSURES**

Not applicable.

**Item 5. OTHER INFORMATION**

During the quarter ended September 30, 2025, none of our directors or officers (as defined in Rule 16a-1(f) of the Securities Exchange Act of 1934) adopted or terminated any Rule 10b5-1 trading arrangement or any non-Rule 10b5-1 trading arrangement (as defined in Item 408 of Regulation S-K).

5.<u>Access to Certain Information; Confidentiality Obligations.</u> 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)During the Term and for a period of two years following the Term, except to the extent not permitted by applicable law or the terms of any agreements entered into by any member of the Company Group with third party service or information providers, the Company agrees that Armstrong shall have the right to (i) receive copies of any materials and analyses prepared by the Company's market fundamentals group (together with Company personnel performing similar functions, the "Fundamentals Group") and (ii) request special research or analyses from the Fundamentals Group; it being understood and agreed that (A) the Fundamentals Group shall give priority to research and analysis requested or required by any member of the Company Group, (B) special research and

------

analyses requests by Armstrong may not be unduly burdensome, and (C) any information or materials provided by the Fundamentals Group to Armstrong shall be and remain the property of the Company Group and shall be subject to the confidentiality obligations referenced in Section 5(b) immediately below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)Armstrong acknowledges and agrees that (i) the confidentiality and non-disclosure obligations set forth in Section 6 of the Original Agreement are incorporated herein by reference and shall remain in full force and effect during the Term and for a period of five years following the Termination Date and (ii) any information or materials provided by the Fundamentals Group to Armstrong pursuant to Section 5(a) above shall constitute "confidential information" obtained by Armstrong that is subject to such confidentiality and non-disclosure obligation (including the exceptions therefrom set forth in the proviso clause of Section 6 of the Original Agreement) until the fifth anniversary of the Termination Date.

6.<u>Cooperation with Litigation.</u> Armstrong agrees to render reasonable assistance to the Company in connection with any litigation or investigation relating to the business of the Company Group.

This Agreement supersedes any and all oral agreements and can only be modified by the Parties in a writing signed by both Parties expressly stating a specific intent to modify this Agreement. This Agreement shall be governed by and construed in accordance with the laws of the State of Texas without giving effect to any choice of law or conflict of law provision or rule (whether of the State of Texas or any other jurisdiction) that would cause the application of the laws of any jurisdiction other than the State of Texas. The Parties hereby submit to the exclusive jurisdiction of the state courts of Texas, located in Harris County.

------

9.<u>Section 409A Compliance</u>. This Agreement shall be interpreted and administered in a manner so that any amount or benefit payable hereunder shall be paid or provided in a manner that is either exempt from or compliant with the requirements of Section 409A of the Internal Revenue Code and applicable Internal Revenue Service guidance and Treasury Regulations issued thereunder ("Section 409A"). If the Parties determine that any payments or benefits to be made or provided hereunder do not comply with Section 409A, the Parties agree to interpret or amend this Agreement or take such other actions as reasonably necessary or appropriate to either (i) remove such payments or benefits from the ambit of Section 409A or (ii) render such payments or benefits compliant thereunder, in any case while preserving to the extent possible the economic agreement of the Parties. Notwithstanding any provision in this Agreement to the contrary, if any payment or benefit provided for herein would be subject to additional taxes and interest under Section 409A if the Employee's receipt of such payment or benefit is not delayed until the Section 409A Payment Date, then such payment or benefit shall not be provided to the Employee (or the Employee's estate, if applicable) until the Section 409A Payment Date. The term "Section 409A Payment Date" means the earlier of (a) the date of the Employee's death or (b) the date that is six months after the date of the Employee's separation from service with the Company (as determined in accordance with Section 409A).

**<u>Section 16 Officers</u>**

«Section 16 Officer»

«Address»

Re:&nbsp;&nbsp;&nbsp;&nbsp;Grant of Phantom Units

Dear «Salutation»:

I am pleased to inform you that, subject to the terms hereof, you have been granted a target number of Phantom Units equal to «LTIP_Grant» as of the above date pursuant to the Company's «LTIP_Plan» Long-Term Incentive Plan (the "Plan"). In addition, in tandem with each Phantom Unit you have been granted a distribution equivalent right (a "DER"). A DER represents the right to receive a cash payment equivalent to the amount, if any, paid in cash distributions on one Common Unit of Plains All American Pipeline, L.P. ("PAA" or the "Partnership") to the holder of such Common Unit. The terms and conditions of this grant are as set forth below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Subject to the further provisions hereof, your Phantom Units shall vest (become payable in the form of one Common Unit of PAA for each Phantom Unit that vests) as set forth below. With respect to Tranche 2 and Tranche 3 below, the actual number of Phantom Units that vest may be lower or higher than the percentage of target Phantom Units associated with such Tranche.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.50% of your Phantom Units ("Tranche 1") will vest on the August 2028 Distribution Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.25% of your Phantom Units ("Tranche 2") will vest pursuant to the terms and conditions described in Exhibit A attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.25% of your Phantom Units ("Tranche 3") will vest pursuant to the terms and conditions described in Exhibit B attached hereto.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.Any Tranche 2 or Tranche 3 Phantom Units that are determined not to have vested as of the August 2028 Distribution Date shall expire effective as of such date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Subject to the further provisions hereof, your DERs shall vest (become payable in cash) as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.The DERs associated with Tranche 1 will begin accruing on the November 2025 Distribution Date and will continue to accrue until the August 2026 Distribution Date, on which date such accrued but unpaid DERs will vest and

**333 Clay Street, Suite 1600 (77002)&nbsp;&nbsp;&nbsp;&nbsp; ■ P.O. Box 4648 ■ Houston, Texas 77210-4648 ■ 713-646-4100**

------

«Section 16 Officer»

August 14, 2025

be paid in a lump sum. Beginning on the November 2026 Distribution Date, such vested DERs will be paid quarterly until the associated Phantom Units vest or are forfeited pursuant to the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.The DERs associated with Tranches 2 and 3 will begin accruing on the November 2025 Distribution Date and will continue to accrue until the associated Phantom Units vest or are forfeited pursuant to the terms hereof. Until such time as a final determination has been made regarding the number of Phantom Units that have vested for Tranche 2 and Tranche 3, such accruals will be based on the assumption that the final "Payout Percentage" as determined pursuant to Exhibit A or Exhibit B, as applicable, equals 100%. Once the final Payout Percentages and the final number of Phantom Units vesting for Tranche 2 and Tranche 3 have been determined, such accrued amounts shall be adjusted upward or downward, as applicable, so that they equal the total amount that would have been accrued in respect of the DERs associated with such vested Phantom Units had the accrual been based on such number of vested Phantom Units commencing on the November 2025 Distribution Date. Unless the Phantom Units subject to this award are forfeited or vest prior to the August 2028 Distribution Date pursuant to paragraphs 5, 6, 7 or 8 below, all accrued and unpaid DERs associated with Tranche 2 and Tranche 3 shall be paid on the August 2028 Distribution Date or as soon thereafter as is administratively practicable.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.The number of Phantom Units and DERs subject to this award, and with respect to the Phantom Units comprising Tranche 3, the distributable cash flow level required for vesting of such Phantom Units, shall be proportionately reduced or increased for any split or reverse split, respectively, of PAA Common Units, or any event or transaction having a similar effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.Upon vesting of any Phantom Units, an equivalent number of DERs will expire. Any such DERs that are payable on the Distribution Date on which the Phantom Units vest, shall be payable on such Distribution Date prior to their expiration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.In the event of the termination of your employment with the Company and its Affiliates for any reason (other than in connection with a Change in Status, Retirement or by reason of your death or "disability," as defined in paragraph 6 below), all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination; provided, however, that if the Company or its Affiliates terminate your employment other than as a result of a Termination for Cause, the following provisions shall apply: (i) if such termination takes place prior to the first anniversary of the date of this grant, all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination; and (ii)

------

«Section 16 Officer»

August 14, 2025

if such termination takes place after the first anniversary of the date of this grant, a "pro rata portion" of the target number of your then outstanding Phantom Units and DERs shall be deemed nonforfeitable on the date of termination and shall vest on the next following Distribution Date. The "pro rata portion" of Phantom Units vesting pursuant to clause (ii) immediately preceding shall be determined by multiplying the target number of your then outstanding Phantom Units by a fraction equal to the number of days between the grant date and the date of termination divided by the number of days between the grant date and the August 2028 Distribution Date (1,096). If the resulting amount includes a fraction, it will be rounded down to the nearest whole number.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.In the event of the termination of your employment with the Company and its Affiliates by reason of your death or your "disability" (a physical or mental infirmity that impairs your ability substantially to perform your duties for a period of eighteen months or that the Company otherwise determines constitutes a "disability"), the following provisions shall apply: (i) if such termination takes place prior to the first anniversary of the date of this grant, all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination; and (ii) if such termination takes place on or after the first anniversary of the date of this grant, (x) all of your then outstanding Phantom Units (which shall be equal to the target number of Phantom Units specified in the first paragraph hereof) shall be deemed nonforfeitable on the date of termination and shall vest on the next following Distribution Date, and (y) any DERs associated with such unvested, nonforfeitable Phantom Units shall not be forfeited on the date of termination, but shall be payable and shall expire on the next following Distribution Date. As soon as administratively practicable after the vesting of any Phantom Units pursuant to this paragraph 6, payment will be made in cash in an amount equal to the Market Value of the number of Phantom Units vesting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.In the event of a Change in Status, (i) all of your then outstanding Phantom Units (which shall be equal to the target number of Phantom Units specified in the first paragraph hereof, except that the Compensation Committee shall have the discretion to adjust the payout level for any Tranche 2 or Tranche 3 Phantom Units based on the performance of the Company under the applicable performance metric taking into account such Change of Control transaction, in each case as reasonably determined by the Compensation Committee) shall be deemed nonforfeitable on such date and shall vest on the next following Distribution Date, and (ii) any DERs associated with such unvested, nonforfeitable Phantom Units shall not be forfeited on such date, but shall be payable and shall expire on the next following Distribution Date.

------

«Section 16 Officer»

August 14, 2025

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.In the event of the termination of your employment with the Company and its Affiliates due to your Retirement, the following provisions shall apply: (i) if such termination takes place prior to the first anniversary of the date of this grant, all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination; and (ii) if such termination takes place on or after the first anniversary of the date of this grant, (x) all of your then outstanding Phantom Units (which shall be equal to the target number of Phantom Units specified in the first paragraph hereof) shall be deemed nonforfeitable on the date of termination and shall vest on the next following Distribution Date, and (y) any DERs associated with such unvested, nonforfeitable Phantom Units shall not be forfeited on the date of termination, but shall be payable and shall expire on the next following Distribution Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.Upon payment pursuant to a DER, the Company will withhold any taxes due from your compensation as required by law. Upon vesting of a Phantom Unit, the Company will withhold any taxes due from your compensation as required by law, which (in the sole discretion of the Company) may include withholding a number of Common Units otherwise payable to you.

As used herein, (i) the "Company" refers to Plains All American GP LLC; (ii) "Distribution Date" means the day in February, May, August or November in any year (as context dictates) that is 45 days after the end of the most recently completed calendar quarter (or, if not a business day, the closest previous business day); (iii) "Market Value" means the average of the closing sales prices for a Common Unit on Nasdaq for the five trading days preceding the then most recent "ex dividend" date for payment of a distribution by the Partnership; and (iv) "Retirement" means termination from full-time employment on terms and timing as approved by the CEO (or by the Board in the case of the CEO).

The phrase "Change in Status" means (A) the termination of your employment by the Company other than a Termination for Cause, within two and a half months prior to or one year following a Change of Control (the "Protected Period"), or (B) the termination of your employment by you due to the occurrence during the Protected Period, without your written consent, of (i) any material diminution in your authority, duties or responsibilities, (ii) any material reduction in your base salary, or (iii) any other action or inaction that constitutes a material breach of this Agreement by the Company. A termination by you pursuant to (B) above shall not be a Change in Status unless (1) you provide written notice to the Company of the condition in (B)(i), (ii) or (iii) that would constitute a Change in Status within 90 days of the initial existence of the condition, and (2) the Company fails to remedy the condition within the 30-day period following such notice.

------

«Section 16 Officer»

August 14, 2025

The phrase "Change of Control" means, and shall be deemed to have occurred upon the occurrence of, one or more of the following events:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)any Person (other than Plains GP Holdings, L.P. ("PAGP") and any affiliate of PAGP that is controlled by PAGP) becomes the beneficial owner, directly or indirectly (in one transaction or a series of related transactions and whether by merger or otherwise), of 50% or more of the membership interest in PAA GP Holdings LLC, a Delaware limited liability company ("PAGP GP")<sup>1</sup>;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)any Person (other than PAGP GP, PAGP or any affiliate of PAGP that is controlled by PAGP) acquires (in one transaction or a series of related transactions and whether by merger or otherwise) direct or indirect control of the general partner interest of PAGP;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)PAGP ceases to retain direct or indirect control (in one transaction or a series of related transactions and whether by merger or otherwise) of the general partner of the Partnership; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)the consummation of a reorganization, merger or consolidation with, or any direct or indirect sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Partnership to, one or more Persons (other than PAGP or any affiliates of PAGP that are controlled by PAGP).

As used in this definition, "Person" shall include any "partnership, limited partnership, syndicate or other group" constituting a "person" within the meaning of such terms pursuant to Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended.

The phrase "Termination for Cause" shall mean severance of your employment with the Company or its Affiliates based on your (i) failure to perform the duties and responsibilities of your position at an acceptable level as reasonably determined in good faith by the CEO of the Company, (ii) conviction of or guilty plea to the committing of an act or acts constituting a felony under the laws of the United States or any state thereof (or Canada or any province thereof) or any misdemeanor involving moral turpitude, or (iii) violation of the Company's Code of Business Conduct (unless waived in accordance with the terms thereof), in the case of clauses (i) and (iii), with the specific failure or violation described to you in writing.

Terms used herein that are not defined herein shall have the meanings set forth in the Plan or, if not defined in the Plan, in the Seventh Amended and Restated Agreement of Limited Partnership of Plains All American Pipeline, L.P., as amended (the "Partnership Agreement").

<sup>1</sup> For the avoidance of doubt, the ownership by a Person of PAGP Class A or Class B shares (or combination thereof) that represent 50% or more of the outstanding Class A and B shares of PAGP (in the aggregate) constitutes indirect ownership of 50% or more of the membership interests in PAGP GP for so long as PAGP directly owns 50% or more of such membership interests in PAGP GP.

**Exhibit A**

**Tranche 2 Vesting Terms<br>(Total Shareholder Return)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.*<u>General</u>*. Consistent with the Company's pay for performance philosophy and in order to more closely align the interests of management with the interests of investors, a portion of your Phantom Units will vest based on PAA's total shareholder return ("TSR") compared to the TSR of a peer group as described below. TSR, which will be calculated using data from Bloomberg, is a primary long-term measure of PAA's performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.*<u>Vesting and Payout</u>*. As soon as administratively feasible following the close of the three-year period ending on June 30, 2028 (the "Performance Period"), the Compensation Committee shall determine and certify the TSR Payout Percentage (as defined below). The Compensation Committee shall make such determination based on a scaled payout range of between 0% and 200% as provided in the table below (the specific payout percentage is referred to as the "TSR Payout Percentage") based on PAA's TSR ranking at the end of the Performance Period compared to the TSR ranking of the various companies and/or indices included in the PAA Peer Group described below. If PAA's absolute TSR is within 50 basis points of the TSR of one or more peer group comparators (i.e., 50 basis points higher or lower), PAA and such comparator(s) shall be deemed to have the same rank and the TSR Payout Percentage shall be equal to the average of the TSR Payout Percentages associated with the relevant rankings as set forth in the table below. If PAA's absolute TSR at the end of the Performance Period is less than 0% and the TSR Payout Percentage is greater than 100%, (i) a TSR Payout Percentage equal to or greater than 125% will be reduced by 25 gross percentage points, and (ii) a TSR Payout Percentage between 100% and 125% will be reduced to 100%. The number of Tranche 2 Phantom Units vesting will be determined by multiplying your target number of Tranche 2 Phantom Units by the TSR Payout Percentage as certified by the Compensation Committee. If the resulting amount includes a fraction, it will be rounded down to the nearest whole number.

In the event any member of the PAA Peer Group files for bankruptcy, liquidates or reorganizes under the United States Bankruptcy Code or other applicable bankruptcy law, such entity shall remain in the PAA Peer Group but shall be deemed to have a TSR of -100% for purposes of calculating the TSR Payout Percentage. In all cases involving the acquisition, merger, reorganization or other material change in ownership, legal structure or business operations of any member of the PAA Peer Group before the end of the Performance Period, the Compensation Committee shall have authority to retain, remove or replace such member, as applicable, for purposes of calculating the TSR Payout Percentage. In connection with any change to the PAA Peer Group, the Compensation Committee shall also have authority to make related adjustments to the rankings and TSR Payout Percentages.

**Exhibit B**

**Tranche 3 Vesting Terms<br>(Cumulative DCF with Leverage Modifier)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.*<u>General</u>*. Consistent with the Company's pay for performance philosophy and in order to more closely align the interests of management with the interests of investors, a portion of your Phantom Units will vest based on PAA's cumulative distributable cash flow ("DCF") per common unit equivalent ("CUE") over a three-year period as described below. PAA's ability to sustain and increase DCF is a primary long-term measure of PAA's performance and is consistent with PAA's overall financial strategy. The final payout calculation will be subject to modification based on leverage levels at the end of the Performance Period; the purpose of the potential leverage modifier is to insure that DCF performance remains tied to leverage levels assumed in PAA's long term plan as of the grant date (the "Grant Date Plan").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.*<u>Vesting and Payout</u>*. As soon as administratively feasible following the close of the three-year period ending on June 30, 2028 (the "Performance Period"), the Compensation Committee shall determine and certify the DCF Payout Percentage (as defined below). The Compensation Committee shall make such determination based on a scaled payout range between 0% and 200% as provided in the table below (the specific payout percentage is referred to as the "DCF Payout Percentage") based on PAA's cumulative DCF per CUE over the Performance Period. If PAA's cumulative DCF per CUE at the end of the Performance Period is between any two of the stated amounts in the table below, the DCF Payout Percentage will be interpolated between the two levels. In addition, the DCF Payout Percentage will be reduced by 25 gross percentage points (the "Leverage Modifier") if PAA's "Leverage Ratio" (long-term debt to adjusted EBITDA as calculated pursuant to PAA's senior unsecured revolving credit facility, modified to include customary adjustments deemed appropriate by the Compensation Committee (for example, a "net debt" adjustment to account for certain cash balances reflected on PAA's balance sheet as of the applicable measurement date)) as of June 30, 2028 is higher than the Leverage Ratio that equals the upper end of PAA's then applicable target Leverage Ratio range (the "Threshold Leverage Ratio") (such range is 2.5x to 3.0x as of the date hereof); if PAA's Leverage Ratio as of June 30, 2028 is equal to or lower than the Threshold Leverage Ratio, there will be no adjustment to the DCF Payout Percentage.

---

| | |
|:---|:---|
| **Cumulative DCF Per CUE Over the Performance Period** | **DCF Payout Percentage** |
| $9.24 (110% of target) | 200% |
| $9.03 | 175% |
| $8.82 | 150% |
| $8.61 | 125% |
| $8.40 (target) | 100% |
| $8.19 | 75% |
| $7.98 | 50% |
| $7.77 | 25% |
| $7.56 (90% of target) | 0% |

---

Note: Both the cumulative DCF per CUE targets set forth in the table above and the initial Threshold Leverage Ratio referenced above are based on the Grant Date Plan, excluding the earnings and leverage impacts of potential asset sales (other than asset sales under contract as of the grant date). Accordingly, when calculating the DCF Payout Percentage, the following adjustments will be made:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)the cumulative DCF per CUE target for the Performance Period as set forth in the table above will be adjusted downward to account for the loss of earnings assumed in the Grant Date Plan for any divested

B-B-1

------

assets, net of avoided interest expense allocable to the divested assets (calculated based on an assumption that 100% of the net sales proceeds from such divestitures are used to reduce debt); and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)with respect to any divested assets that were included as divestitures in the Grant Date Plan, the Threshold Leverage Ratio target will be adjusted to reflect the leverage impact of any such divested assets based on the assumptions originally set forth in the Grant Date Plan.

In addition, for the Leverage Modifier, the Leverage Ratio calculation will be adjusted up or down as appropriate to neutralize the impact on leverage of any DCF per CUE over or under performance that has already been taken into account in determining the final amount of cumulative DCF per CUE during the Performance Period (with the goal of isolating the balance sheet impact of other actions such as timing and amount of asset sales, amount of capital expenditures, etc.). In addition, the Compensation Committee shall have the ability to make adjustments to the Leverage Ratio calculation to the extent deemed appropriate in connection with leverage attributable to a transaction or project approved by the Company's Board of Directors (including, without limitation, transactions involving changes to the Company's capital structure). The number of Tranche 3 Phantom Units vesting will be determined by multiplying your target number of Tranche 3 Phantom Units by the DCF Payout Percentage as certified by the Compensation Committee. If the resulting amount includes a fraction, it will be rounded down to the nearest whole number.

Illustrative Examples (based on an assumed target number of Tranche 3 Phantom Units of 1,000 and based on an assumed Threshold Leverage Ratio of 3.0x, which is the Leverage Ratio that is equal to the upper end of PAA's current target Leverage Ratio range of 2.5x to 3.0x):

Re:&nbsp;&nbsp;&nbsp;&nbsp;Grant of Phantom Units

Dear [Name]:

I am pleased to inform you that, subject to the terms hereof, you have been granted [Number] Phantom Units as of the above date pursuant to the Company's 2021 Long-Term Incentive Plan (the "Plan"). In addition, in tandem with each Phantom Unit you have been granted a distribution equivalent right (a "DER"). A DER represents the right to receive a cash payment equivalent to the amount, if any, paid in cash distributions on one Common Unit of Plains All American Pipeline, L.P. ("PAA" or the "Partnership") to the holder of such Common Unit. The terms and conditions of this grant are as set forth below.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1.Subject to the further provisions hereof, your Phantom Units shall vest (become payable in the form of one Common Unit of PAA for each Phantom Unit that vests) on the August 2030 Distribution Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2.Subject to the further provisions hereof, your DERs shall vest (become payable in cash) as follows:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;a.20% of the DERs will begin accruing on the November 2025 Distribution Date and will continue to accrue until the August 2026 Distribution Date, on which date such accrued but unpaid DERs will vest and be paid in a lump sum. Beginning on the November 2026 Distribution Date, such vested DERs will be paid quarterly until the associated Phantom Units vest or are forfeited pursuant to the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b.An additional 20% of the DERs will vest on the August 2026 Distribution Date, and, beginning on the November 2026 Distribution Date, such vested DERs will be paid quarterly until the associated Phantom Units vest or are forfeited pursuant to the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;c.An additional 20% of the DERs will vest on the August 2027 Distribution Date, and, beginning on the November 2027 Distribution Date, such vested DERs will be paid quarterly until the associated Phantom Units vest or are forfeited pursuant to the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;d.An additional 20% of the DERs will vest on the August 2028 Distribution Date, and, beginning on the November 2028 Distribution Date, such vested DERs will be paid quarterly until the associated Phantom Units vest or are forfeited pursuant to the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;e.An additional 20% of the DERs will vest on the August 2029 Distribution Date, and, beginning on the November 2029 Distribution Date, such vested DERs will be paid quarterly until the associated Phantom Units vest or are forfeited pursuant to the terms hereof.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3.The number of Phantom Units and DERs subject to this award shall be proportionately reduced or increased for any split or reverse split, respectively, of PAA Common Units, or any event or transaction having a similar effect.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4.Upon vesting of any Phantom Units, an equivalent number of DERs will expire. Any such DERs that are payable on the Distribution Date on which the Phantom Units vest, shall be payable on such Distribution Date prior to their expiration.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5.In the event of the termination of your employment with the Company and its Affiliates for any reason (other than in connection with a Change in Status, Retirement or by reason of your death or "disability," as defined in paragraph 6 below), all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination; provided, however, that if the Company or its Affiliates terminate your employment other than as a result of a Termination for Cause, the following provisions shall apply: (i) if such termination takes place prior to the first anniversary of the date of this grant, all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination; and (ii) if such termination takes place after the first anniversary of the date of this grant, a "pro rata portion" of your then outstanding Phantom Units and DERs shall be deemed nonforfeitable on the date of termination and shall vest on the next following Distribution Date. The "pro rata portion" of Phantom Units vesting pursuant to clause (ii) immediately preceding shall be determined by multiplying the number of your then outstanding Phantom Units by a fraction equal to the number of days between the grant date and the date of termination divided by the number of days between the grant date and the August 2030 Distribution Date (1,826). If the resulting amount includes a fraction, it will be rounded down to the nearest whole number.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;6.In the event of the termination of your employment with the Company and its Affiliates by reason of your death or your "disability" (a physical or mental infirmity that impairs your ability substantially to perform your duties for a period of eighteen months or that the Company otherwise determines constitutes a "disability"), the following provisions shall apply: (i) if such termination takes place prior to the first

As soon as administratively practicable after the vesting of any Phantom Units pursuant to this paragraph 6, payment will be made in cash in an amount equal to the Market Value of the number of Phantom Units vesting.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;7.In the event of a Change in Status, (i) all of your then outstanding Phantom Units shall be deemed nonforfeitable on such date and shall vest on the next following Distribution Date, and (ii) any DERs associated with such unvested, nonforfeitable Phantom Units shall not be forfeited on such date, but shall be payable and shall expire on the next following Distribution Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;8.In the event of the termination of your employment with the Company and its Affiliates due to your Retirement, the following provisions shall apply: (i) if such termination takes place prior to the first anniversary of the date of this grant, all of your then outstanding Phantom Units and DERs shall automatically be forfeited as of the date of termination; and (ii) if such termination takes place on or after the first anniversary of the date of this grant, (x) all of your then outstanding Phantom Units shall be deemed nonforfeitable on the date of termination and shall vest on the next following Distribution Date, and (y) any DERs associated with such unvested, nonforfeitable Phantom Units shall not be forfeited on the date of termination, but shall be payable and shall expire on the next following Distribution Date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;9.Upon payment pursuant to a DER, the Company will withhold any taxes due from your compensation as required by law. Upon vesting of a Phantom Unit, the Company will withhold any taxes due from your compensation as required by law, which (in the sole discretion of the Company) may include withholding a number of Common Units otherwise payable to you.

"Retirement" means termination from full-time employment on terms and timing as approved by the CEO (or by the Board in the case of the CEO).

The phrase "Change in Status" means (A) the termination of your employment by the Company other than a Termination for Cause, within two and a half months prior to or one year following a Change of Control (the "Protected Period"), or (B) the termination of your employment by you due to the occurrence during the Protected Period, without your written consent, of (i) any material diminution in your authority, duties or responsibilities, (ii) any material reduction in your base salary, or (iii) any other action or inaction that constitutes a material breach of this Agreement by the Company. A termination by you pursuant to (B) above shall not be a Change in Status unless (1) you provide written notice to the Company of the condition in (B)(i), (ii) or (iii) that would constitute a Change in Status within 90 days of the initial existence of the condition, and (2) the Company fails to remedy the condition within the 30-day period following such notice.

The phrase "Change of Control" means, and shall be deemed to have occurred upon the occurrence of, one or more of the following events:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i)any Person (other than Plains GP Holdings, L.P. ("PAGP") and any affiliate of PAGP that is controlled by PAGP) becomes the beneficial owner, directly or indirectly (in one transaction or a series of related transactions and whether by merger or otherwise), of 50% or more of the membership interest in PAA GP Holdings LLC, a Delaware limited liability company ("PAGP GP")<sup>1</sup>;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(ii)any Person (other than PAGP GP, PAGP or any affiliate of PAGP that is controlled by PAGP) acquires (in one transaction or a series of related transactions and whether by merger or otherwise) direct or indirect control of the general partner interest of PAGP;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iii)PAGP ceases to retain direct or indirect control (in one transaction or a series of related transactions and whether by merger or otherwise) of the general partner of the Partnership; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(iv)the consummation of a reorganization, merger or consolidation with, or any direct or indirect sale, lease, exchange or other transfer (in one transaction or a series of related transactions) of all or substantially all of the assets of the Partnership to, one or more Persons (other than PAGP or any affiliates of PAGP that are controlled by PAGP).

<sup>1</sup> For the avoidance of doubt, the ownership by a Person of PAGP Class A or Class B shares (or combination thereof) that represent 50% or more of the outstanding Class A and B shares of PAGP (in the aggregate) constitutes indirect ownership of 50% or more of the membership interests in PAGP GP for so long as PAGP directly owns 50% or more of such membership interests in PAGP GP.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. I have reviewed this quarterly report on Form 10-Q of Plains All American Pipeline, L.P. (the "registrant");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

The registrant's other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Designed such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that material information relating to the registrant, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in which this report is being prepared;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(d)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Disclosed in this report any change in the registrant's internal control over financial reporting that occurred during the registrant's most recent fiscal quarter (the registrant's fourth fiscal quarter in the case of an annual report) that has materially affected, or is reasonably likely to materially affect, the registrant's internal control over financial reporting; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;5. The registrant's other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the registrant's auditors and the audit committee of the registrant's board of directors (or persons performing the equivalent functions):

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(a)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; All significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to adversely affect the registrant's ability to record, process, summarize and report financial information; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(b)&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; Any fraud, whether or not material, that involves management or other employees who have a significant role in the registrant's internal control over financial reporting.
