The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Fair Value of the Preferred Distribution Rate Reset Option

As described in Note 12 to the consolidated financial statements, the Preferred Distribution Rate Reset Option of the Plains All American Pipeline, L.P.

(PAA) Series A preferred units was an embedded derivative that was bifurcated from the related host contract and recorded at fair value.

The fair value on the settlement date was $131 million, which resulted in a gain of $58 million recognized in other income.

Management determined the fair value based on a Monte Carlo valuation model that estimated the fair value of the Series A preferred units with and without the Preferred Distribution Rate Reset Option.

This model relied on assumptions for forecasts for the ten-year U.S.

Treasury rate, the PAA common unit price, and default probabilities which impacted timing estimates as to when the option will be exercised.

The principal considerations for our determination that performing procedures relating to the fair value of the Preferred Distribution Rate Reset Option is a critical audit matter are the significant judgment by management when developing the fair value estimate of the Preferred Distribution Rate Reset Option using the Monte Carlo valuation model.

This in turn led to a high degree of auditor judgment, subjectivity, and effort in performing procedures and evaluating the Monte Carlo valuation model and management’s significant assumption related to forecasts for the ten-year U.S.

Treasury rate.

Also, the audit effort involved the use of professionals with specialized skill and knowledge.

Revenue Recognition – Crude Oil Sales

As described in Note 3 to the consolidated financial statements, revenue from sales of crude oil 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.

The Partnership recognized crude oil sales of $47,036 million for the year ended December 31, 2024.

The principal consideration for our determination that performing procedures relating to revenue recognition for crude oil sales is a critical audit matter is a high degree of auditor effort in performing procedures related to the Partnership’s revenue recognition.

Addressing the matter involved performing procedures and evaluating audit evidence in connection with forming our overall opinion on the consolidated financial statements.

These procedures included testing the effectiveness of controls relating to the fair value of the Preferred Distribution Rate Reset Option, including the appropriateness of the Monte Carlo valuation model, the significant assumption, and data used in developing the fair value estimate.

These procedures also included, among others (i) testing the completeness and accuracy of the contractual information from the Series A preferred unit agreement that is used in the valuation model, (ii) evaluating the reasonableness of, and testing the accuracy of, inputs used to estimate the fair value of the Preferred Distribution Rate Reset Option, and (iii) the involvement of professionals with specialized skill and knowledge to assist in evaluating the reasonableness of management’s estimate by developing (a) an independent Monte Carlo valuation model and (b) an independent range of fair values using independently developed forecasts for the ten-year U.S.

Treasury rate and comparing the independent range of fair values to management’s estimate.

These procedures included testing the effectiveness of controls relating to the revenue recognition process for crude oil sales.

These procedures also included, among others (i) testing revenue recognized for a sample of crude oil sales revenue transactions by obtaining and inspecting source documents, such as contracts, settlement statements, invoices, and payment receipts and (ii) confirming a sample of outstanding customer invoice balances as of December 31, 2024, and for confirmations not returned, obtaining and inspecting source documents, such as contracts, settlement statements, invoices, and subsequent payment receipts.

In addition, when we evaluate property and equipment and other long-lived assets for recoverability, it may also be necessary to review related depreciation estimates and methods.

We did not recognize any material impairments during the year ended December 31, 2023.

During the fourth quarter of 2024, we recognized approximately $ 140 million of non-cash charges related to the write-down of certain of our long-lived U.S.

based NGL terminal assets included in our NGL segment due to asset impairments and accelerated depreciation.

Such charges are reflected in “(Gains)/losses on asset sales, asset impairments and other, net” on our Consolidated Statement of Operations.

We have experienced a decrease in demand for our services at certain of our terminals within two asset groups related to changing market conditions specific to their locations, which was a triggering event that required us to assess the recoverability of carrying value of such long-lived assets.

As a result of our impairment review, we wrote-off the portion of the carrying amount of these long-lived assets that exceeded their fair value.

Our estimated fair value was based on the determination that a portion of the long-lived assets had no residual value.

We consider such inputs to be a Level 3 input in the fair value hierarchy.

Further, we determined that an acceleration of depreciation was appropriate for another portion of the long-lived assets.

We did not recognize any material asset impairments during the year ended December 31, 2023.

During the third quarter of 2022, we temporarily ceased service on a crude oil pipeline in California as a precautionary measure following a routine inspection and initiated a program of additional tests and inspections.

As a result of our impairment review, we wrote off the portion of the carrying amount of these long-lived assets that exceeded their fair value.

We recognized a non-cash loss of approximately $ 330 million, which amount is reflected in “ (Gains)/losses on asset sales and asset impairments, net ” on our Consolidated Statement of Operations.

We recognized a non-cash loss of approximately $ 330 million, which amount is reflected in “ (Gains)/losses on asset sales, asset impairments and other, net ” on our Consolidated Statement of Operations.

Our estimated fair values (which we consider a Level 3 measurement in the fair value hierarchy) were based upon a discounted cash flow approach utilizing various assumptions and the application of a discount rate of approximately 15 %, which represents our estimate of the cost of capital of a theoretical market participant for the asset group.

Such assumptions included (but were not limited to) (i) future commodity volumes (consistent with historical information and estimates of future drilling and completion activity), (ii) tariff rates, (iii) estimated fixed and variable costs, (iv) the length of time the assets operate and (v) the amount for which assets in the asset group could be sold.

During the year ended December 31, 2021, we recognized approximately $ 220 million of non-cash impairment losses related to certain crude oil storage terminal assets included in our Crude Oil segment.

This amount is reflected in “ (Gains)/losses on asset sales and asset impairments, net ” on our Consolidated Statements of Operations.

Decreased demand for our services related to changing market conditions resulted in decreases in expected future cash flows for certain of our assets, which was a triggering event that required us to assess the recoverability of our carrying value of such long-lived assets.

As a result of our impairment review, we wrote off the portion of the carrying amount of these long-lived assets that exceeded their fair value.

Our estimated fair value (which we consider a Level 3 measurement in the fair value hierarchy) was primarily based upon an assumption for the amount for which the relevant assets and land could be sold.

Other Acquisitions

In January 2025, we acquired Ironwood Midstream Energy Partners II, LLC, which owns a gathering system in the Eagle Ford Basin, for approximately $ 475 million from EnCap Flatrock Midstream.

In January 2025, in a separate transaction, we also repurchased from EnCap Flatrock Midstream, approximately 18 % of our outstanding Series A preferred units, which equated to less than 2 % of our outstanding common units and Series A preferred units combined (our “common unit equivalents”).

EnCap Flatrock Midstream is affiliated with EnCap Investments, L.P., an entity that is associated with a member of the board of directors of our general partner.

See Note 11 for additional information.

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 $ 161 million (approximately $ 105 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.

EMG Medallion 2 Holdings was a portfolio company of The Energy & Minerals Group (“EMG”), which is associated with a member of the board of directors of our general partner.

During the year ended December 31, 2024, we also completed the following acquisitions:

• the acquisition in December 2024 of the remaining 50 % interest in Midway Pipeline LLC (“Midway”) for approximately $ 90 million.

As a result of this transaction, we now own 100 % of Midway and reflect such entity as a consolidated subsidiary in our Consolidated Financial Statements.

The remeasurement of our previously-held investment in Midway to fair value resulted in a gain of approximately $ 15 million.

This gain is reflected in “Gain on investments in unconsolidated entities, net” on our Consolidated Statement of Operations.

• the acquisition of additional interests in certain unconsolidated entities, including (i) the acquisition in August 2024 of an additional approximate 0.67 % interest in Wink to Webster Pipeline LLC (increasing our ownership interest from 16 % to 17 %) for $ 20 million and (ii) the acquisition in March 2024 of an additional 10 % interest in Saddlehorn Pipeline Company, LLC (increasing our ownership interest from 30 % to 40 %) for $ 91 million.

See Note 8 for additional information about our investments in unconsolidated entities.

• the acquisition in the second and third quarters of 2024 of pipeline and terminal assets within our asset footprint for approximately $ 32 million.

In November 2023, we acquired a crude oil gathering system in the Northern Delaware Basin from a subsidiary of LM Energy Partners for approximately $ 135 million (approximately $ 88 million net to our 65 % interest in the Permian JV), subject to certain adjustments.

As a result of this transaction, we now own 100 % of Advantage and its subsidiaries and such entities are reflected as consolidated subsidiaries in our Consolidated Financial Statements.

• the acquisition in October 2022 of an additional ownership interest in certain straddle plants included in our NGL segment in a non-cash transaction whereby we agreed to provide processing capacity over a 50-year term at specified terms and conditions.

This transaction was accounted for as an asset acquisition.

The fair value of the straddle plant assets acquired and liabilities assumed was approximately $ 122 million, and we recognized an equally offsetting contract liability that will be amortized on a straight-line basis into “Services revenue” over the 50-year term of the agreement.

Asset Exchange

In June 2021, we closed on an asset exchange agreement (the “Asset Exchange”) with Inter Pipeline Ltd., through which we acquired additional interests in two straddle plants included in our NGL segment that we currently operate, in exchange for a pipeline and related storage and truck offload facilities previously included in our Crude Oil segment and cash consideration of $ 32 million, including working capital and other adjustments.

We recognized a gain of $ 106 million on the divestiture of the pipeline and related storage and truck offload facilities, which is included in “(Gains)/losses on asset sales and asset impairments, net” on our Consolidated Statement of Operations, based on the difference between the fair value of the divested assets and their carrying value.

Joint Venture Transaction

In October 2021, we and Oryx Midstream completed the merger, in a cashless, debt-free transaction, of our respective Permian Basin assets, operations and commercial activities into a newly formed joint venture, the Permian JV.

The Permian JV includes all of Oryx Midstream’s Permian Basin assets and, with the exception of our long-haul pipeline systems and certain of our intra-basin terminal assets, the vast majority of our assets located within the Permian Basin.

We own 65 % of the Permian JV, operate the combined assets and reflect the Permian JV as a consolidated subsidiary in our consolidated financial statements.

The formation of the joint venture was accounted for as a business combination using the acquisition method of accounting.

As the majority owner and the controlling entity, we are considered the acquirer and the transfer of our predecessor business to the joint venture was accounted for at historical cost, while the Oryx Midstream predecessor business was recorded based on the fair value of the assets acquired and liabilities assumed.

In accordance with applicable accounting guidance, the fair value of Oryx Midstream’s ownership interest in the joint venture following the formation of $ 3.230 billion is utilized as the consideration transferred for the purchase price allocation.

The combination of the historical cost and fair value, discussed above, resulted in net assets of the joint venture of approximately $ 7.529 billion upon formation.

Oryx Midstream’s 35 % interest in the net assets of the Permian JV was recognized as noncontrolling interest in partners’ capital.

The difference between such amount and the fair value of Oryx Midstream’s assets acquired and liabilities assumed was recorded as an increase to partners’ capital attributable to our Class A shareholders and noncontrolling interests in PAA and AAP in proportion to their respective ownership interests.

NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS

The following table presents the amounts recognized in partners’ capital associated with this transaction (in millions):

Recognized Amount

Oryx Midstream’s 35 % interest in the Permian JV

Increase to partners’ capital attributable to noncontrolling interests in PAA and AAP 432

Noncontrolling interests $ 3,067

Class A shareholders 163

Total partners’ capital $ 3,230

The fair value of the $ 3.230 billion consideration is a Level 3 measurement in the fair value hierarchy and was determined by valuing both the enterprise value of Oryx Midstream’s Permian Basin business and the enterprise value of our Permian Basin assets that were contributed to the joint venture.

The enterprise value of Oryx Midstream’s Permian Basin business was calculated by weighting the results of (i) a discounted cash flow approach and (ii) a guideline public company method (“GPCM”).

The value of our Permian Basin assets that were contributed to the joint venture was based on a GPCM.

The discounted cash flow approach utilized a discount rate of 12 %, based on our estimate of the risk that a theoretical market participant would assign to the business.

The projection of future crude volumes gathered and transported was also a key assumption in the discounted cash flow approach and was based on projected rig activity on the associated acreage.

The GPCM applies market multiples to estimated earnings to derive the fair value.

The GPCM values for Oryx Midstream’s Permian Basin business and for our Permian Basin assets that were contributed to the joint venture assumed market multiples ranging from 9.5 to 11.0 , which were derived from assumptions of market multiples for similar businesses.

The determination of the fair value of the assets acquired and liabilities assumed was estimated in accordance with the applicable accounting guidance.

The analysis was performed based on estimates that are reflective of market participant assumptions.

The following table reflects our determination of the fair value of those assets and liabilities (in millions):

Identifiable Assets Acquired and Liabilities Assumed Estimated Useful Lives

(in years) Recognized Amount

Property and equipment 3 - 30

Intangible assets 20 1,247

Investment in unconsolidated entities N/A 103

Working capital and other assets and liabilities N/A ( 6 )

The fair value of the tangible assets is a Level 3 measurement in the fair value hierarchy and was determined using a cost approach based on costs incurred on similar recent construction projects.

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 16 %, based on our estimate of the risk that a theoretical market participant would assign to the respective intangible assets.

The projection of future crude oil volumes gathered and transported was also a key assumption in the valuation of the intangible assets and was based on projected rig activity on the associated acreage.

The fair value of intangible assets is comprised of customer relationships that will be amortized over their useful lives, which have a remaining weighted average life of approximately 20 years.

The value assigned to such intangible assets will be amortized to earnings under the declining balance method of amortization.

Amortization expense was approximately $ 138 million, $ 142 million and $ 28 million during the years ended December 31, 2023, 2022 and 2021, respectively, and the future amortization expense through 2026 is estimated as follows (in millions):

During the year ended December 31, 2021, we incurred approximately $ 17 million of transaction-related costs associated with the joint venture formation transaction.

Such costs are reflected as a component of “General and administrative expenses” on our Consolidated Statements of Operations.

Distributions of available cash from the Permian JV to PAA and Oryx Midstream are subject to a tiered modified sharing arrangement (“MSA”) for up to ten years .

Pursuant to the terms of the governing documents for the Permian JV, the MSA will terminate in October 2031, or sooner if Oryx Midstream exercises its right to terminate the MSA at any time by delivery of written notice to PAA.

Upon termination of the MSA, monthly distributions of available cash will be paid 65 % to PAA and 35 % to Oryx.

Through the third quarter of 2022, the Permian JV made quarterly distributions, but starting in December 2022, the Permian JV began making monthly distributions to the members after renegotiation of the MSA.

Under the MSA, distributions will be allocated as follows (in millions):

Available Cash Distributions Percentages

1 Up to $300 50 % 50 %

2 $300 - $428 100 % —%

3 $428 - $815 65 % 35 %

4 $815 and above 70 % 30 %

Oryx Midstream is a portfolio company of Stonepeak Infrastructure Partners (“Stonepeak”).

Affiliates of Stonepeak own approximately 8.9 % of PAA’s outstanding Series A preferred units, which equates to less than 1 % of PAA’s outstanding common units and Series A preferred units (PAA’s “common unit equivalents”) combined.

Pro Forma and Other Financial Results

Financial results of the Permian JV have been included in the results of operations within the Crude Oil segment since the date of the formation.

Disclosure of the revenues and earnings from the Oryx Midstream predecessor business for the period subsequent to the joint venture formation is not practicable as it is not being operated as a standalone subsidiary.

Our other related parties include (i) entities in which we hold investments and account for under the equity method of accounting (see Note 8 for information regarding such entities) and (ii) principal owners and their affiliated entities.

We recognize as our principal owners entities that have a designated representative on the board of directors of PAGP GP and/or own greater than 10 % of the limited partner interests in AAP.

Such limited partner interests in AAP translate into a significantly smaller indirect ownership interest in PAA.

As the “responsible party” for the Line 901 incident we are liable for various costs and for certain natural resource damages under the Oil Pollution Act.

In this regard, following the Line 901 incident, we entered into a cooperative Natural Resource Damage Assessment (“NRDA”) process with the federal and state agencies designated or authorized by law to act as trustees for the natural resources of the United States and the State of California (collectively, the “Trustees”).

Additionally, various government agencies sought to collect civil fines and penalties under applicable state and federal regulations.

On March 13, 2020, the United States and the People of the State of California filed a civil complaint against Plains All American Pipeline, L.P.

and Plains Pipeline L.P.

along with a pre-negotiated settlement agreement in the form of a Consent Decree (the “Consent Decree”) that was signed by the United States Department of Justice, Environmental and Natural Resources Division, the United States Department of Transportation, Pipeline and Hazardous Materials Safety Administration, the EPA, CDFW, the California Department of Parks and Recreation, the California State Lands Commission, the California Department of Forestry and Fire Protection’s Office of the State Fire Marshal, Central Coast Regional Water Quality Control Board, and Regents of the University of California.

The Consent Decree was approved and entered by the Federal District Court for the Central District of California on October 14, 2020.

Pursuant to the terms of the Consent Decree, Plains paid $ 24 million in civil penalties and $ 22.325 million as compensation for injuries to, destruction of, loss of, or loss of use of natural resources resulting from the Line 901 incident.

The Consent Decree, which resolved all regulatory claims related to the incident, also contains requirements for implementing certain agreed-upon injunctive relief, as well as requirements for potentially restarting Line 901 and the Sisquoc to Pentland portion of Line 903.

On October 13, 2022, Plains sold Line 901 and the Sisquoc to Pentland portion of Line 903 to Pacific Pipeline Company, an indirect wholly owned subsidiary of Exxon Mobil Corporation.

As required by the terms of the Consent Decree, such purchaser assumed responsibility for compliance with the Consent Decree as it relates to the future ownership and operation of Line 901 and the Sisquoc to Pentland portion of Line 903.

Following an investigation and grand jury proceedings, in May of 2016, PAA was charged by a California state grand jury, pursuant to an indictment filed in California Superior Court, Santa Barbara County (the “May 2016 Indictment”), with alleged violations of California law in connection with the Line 901 incident.

Fifteen charges from the May 2016 Indictment were the subject of a jury trial in California Superior Court in Santa Barbara County, and the jury returned a verdict on September 7, 2018, pursuant to which we were (i) found guilty on one felony discharge count and eight misdemeanor counts (which included one reporting count, one strict liability discharge count and six strict liability animal takings counts) and (ii) found not guilty on one strict liability animal takings count.

The remaining counts were subsequently dismissed by the Court.

On April 25, 2019, PAA was sentenced to pay fines and penalties in the aggregate amount of just under $ 3.35 million for the convictions covered by the September 2018 jury verdict (the “2019 Sentence”).

The fines and penalties imposed in connection with the 2019 Sentence have been paid.

In September 2021, the Superior Court concluded a series of hearings on the issue of whether there were any “direct victims” of the spill that are entitled to restitution under applicable criminal law.

Through a series of final orders issued at the trial court level and without affecting any rights of the claimants under civil law, the Court dismissed the vast majority of the claims and ruled that the claimants were not entitled to restitution under applicable criminal laws.

The Court did award an aggregate amount of less than $ 150,000 to a handful of claimants and we settled with approximately 40 claimants before the hearings for aggregate consideration that is not material.

The prosecution and certain separately represented claimants have appealed the Court’s rulings.

We also received several individual lawsuits and claims from companies, governmental agencies and individuals alleging damages arising out of the Line 901 incident.

Several pending or recently resolved lawsuits and claims were filed by companies, governmental agencies and individuals alleging damages arising out of the Line 901 incident.

These lawsuits and claims generally seek restitution, compensatory and punitive damages, and/or injunctive relief.

The majority of these lawsuits have been settled or dismissed by the court.

In addition to the other lawsuits disclosed herein, the following lawsuits remain:

(i) a lawsuit filed in the United States District Court for the Central District of California that was remanded to the California Superior Court in Santa Barbara County for lost revenue or profit asserted by a former oil producer that declared bankruptcy and shut in its offshore production platform following the Line 901 incident;

(ii) a lawsuit filed by the California State Land Commission in California Superior Court in Santa Barbara County seeking lost royalties following the shut-down of Line 901, as well as costs related to the decommissioning of such platform, and (iii) lawsuits filed in California Superior Court in Santa Barbara County by various companies and individuals who provided labor, goods, or services associated with oil production activities they claim were disrupted following the Line 901 incident.

We are vigorously defending these remaining lawsuits and believe we have strong defenses.

Furthermore, shortly following the Line 901 incident, we established a claims line and encouraged any parties that were damaged by the release to contact us to discuss their damage claims.

We received a number of claims through the claims line and we have processed those claims and made payments as appropriate.

Most of these lawsuits have been settled or dismissed by the court.

We recently settled the following two lawsuits (the “2024 Settlements”):

(i) a lawsuit in California Superior Court in Santa Barbara County for lost revenue or profit asserted by a former oil producer that declared bankruptcy and shut in its offshore production platform following the Line 901 incident;

and (ii) a lawsuit filed by the California State Land Commission in California Superior Court in Santa Barbara County seeking lost royalties following the shut-down of Line 901, as well as costs related to the decommissioning of such platform.

In connection with the 2024 Settlements, we recognized additional costs related to the Line 901 incident of $ 120 million.

Our remaining Line 901 lawsuits include various lawsuits filed in California Superior Court in Santa Barbara County by (x) companies and individuals who provided labor, goods, or services associated with oil production activities they claim were disrupted following the Line 901 incident and (y) a landowner on an adjacent pipeline alleging property damage from the “stigma” of the Line 901 incident.

We are vigorously defending these remaining lawsuits, which have not yet been set for trial, and believe we have strong defenses.

The ultimate outcome of such matters is uncertain, and an unfavorable resolution could have a material impact on our results of operations.

Additionally, a class action lawsuit was filed against us in United States District Court for the Central District of California in which the class plaintiffs seek a declaratory judgment that Plains’ right-of-way agreements would not allow Plains to lay a new pipeline to replace Line 901 and/or the non-operating segment of Line 903 without paying additional compensation.

The purchaser of Line 901 and the Sisquoc to Pentland portion of Line 903 has assumed liability for these claims with respect to its interest in such acquired pipelines and Plains has been dismissed from this portion of the lawsuit.

In the same proceeding, a small subset of plaintiffs are also claiming damages to compensate them for the alleged diminished value of their properties due to the stigma of the oil spill.

We are vigorously defending against these stigma damages claims.

In a separate class action lawsuit that was pending in United States District Court for the Central District of California, the plaintiffs claimed two different classes of claimants were damaged by the release:

(i) commercial fishermen who landed fish in certain specified fishing blocks in the waters off the coast of Southern California or persons or businesses who resold commercial seafood caught in those areas;

and (ii) owners and lessees of residential beachfront properties, or properties with a private easement to a beach, where plaintiffs claim oil from the spill washed up.

In 2022, in order to fully and finally resolve all claims and litigation for both classes, we reached an agreement to settle this case in exchange for a payment of $ 230 million (the “Class Action Settlement”).

The Class Action Settlement was formally approved by the trial court on September 20, 2022, and we made the $ 230 million settlement payment on October 27, 2022 and the lawsuit was subsequently dismissed.

Plains formally submitted claims for reimbursement of the Class Action Settlement to our insurance carriers on November 7, 2022.

To date, we have received payment of approximately $ 3.6 million from one insurer, which represents the final payment obligation of such insurer and brings the total amount collected from all insurers under such program to $ 275 million of the $ 500 million policy limits as of December 31, 2023.

Insurers responsible for $ 185 million of the remaining $ 225 million of coverage formally communicated a denial of coverage for the Class Action Settlement generally alleging that some or all damages encompassed by the Class Action Settlement are not covered by their policies and that all or some portion of the $ 275 million for which Plains has already received insurance reimbursement does not properly exhaust the underlying policies that paid those sums.

The insurer responsible for the final $ 40 million of coverage under such insurance program has not formally responded to our reimbursement demands.

We have initiated final and binding arbitration proceedings against the insurers responsible for $ 175 million of coverage and intend to vigorously pursue recovery from our insurers of all amounts for which we have claimed reimbursement.

We believe that our claim for reimbursement from our insurers of the Class Action Settlement payment is strong and that our ultimate recovery of such amounts is probable.

Our belief is based on:

(i) our analysis of the terms of the underlying insurance policies as applied to the facts and circumstances that comprise our claim for reimbursement, (ii) our experience with the cost submissions and timely collection of claims for the $ 275 million collected to date for this incident under the same insurance program as the denied claims, including from some of the same insurers who are now denying claims, (iii) our extensive legal review and assessment of the insurer’s claimed basis for denial of coverage, which review and assessment includes the advice of external legal counsel experienced in these type of matters and solidly supports our belief that our insurers are required to provide coverage based on the terms of the policies and the nature of our claims, and (iv) the financial strength of the insurance carriers as determined by an independent credit ratings agency.

Various factors could impact the timing and amount of recovery of our insurance receivable, including future developments that adversely impact our assessment of the strength of our coverage claims, the outcome of any dispute resolution proceedings with respect to our coverage claims and the extent to which insurers may become insolvent in the future.

An unfavorable resolution could have a material impact on our results of operations.

In November 2022, we submitted claims to several of our insurance carriers seeking reimbursement for a $ 230 million payment made in October of 2022 to settle a class action lawsuit stemming from the Line 901 incident (the “Class Action Settlement”).

We had previously received payment of approximately $ 3.6 million from one insurer, which represented the final payment obligation of such insurer and brought the total amount collected from all insurers under such program to $ 275 million of the $ 500 million policy limits.

In response to denials of coverage or other failures to timely tender payment, we initiated final and binding insurance arbitration proceedings against the insurers responsible for the remaining $ 225 million of coverage.

Such insurers generally alleged that some or all damages encompassed by the Class Action Settlement were not covered by their policies and that all or some portion of the $ 275 million for which we had already received insurance reimbursement did not, for purposes of determining whether their policies were triggered, properly exhaust the underlying policies that paid those sums.

As of December 31, 2023, we believed that our claim for reimbursement was probable of recovery despite the ongoing arbitration proceedings.

Our belief at that time was based on:

(i) our analysis of the terms of the underlying insurance policies as applied to the facts and circumstances that comprised our claim for reimbursement, (ii) our experience with the cost submissions and timely collection of claims for the $ 275 million previously collected for this incident under the same insurance program as the denied claims, including from some of the same insurers who were then denying claims, (iii) our extensive legal review and assessment of the insurer’s claimed basis for denial of coverage, which review and assessment included the advice of external legal counsel experienced in these type of matters that supported our belief that our insurers were required to provide coverage based on the terms of the policies and the nature of our claims, and (iv) the financial strength of the insurance carriers as determined by an independent credit ratings agency.

However, at that time we also noted that various factors could impact the timing and amount of recovery of our insurance receivable, including future developments that adversely impacted our assessment of the strength of our coverage claims, the outcome of any dispute resolution proceedings with respect to our coverage claims (including arbitration proceedings) and the extent to which insurers may become insolvent in the future.

A binding arbitration hearing with respect to our insurance claim against insurers representing $ 175 million of our total $ 225 million reimbursement claim concluded in early October 2024, and the arbitration panel’s final and binding decision was returned in January 2025.

The panel ruled that a substantial portion of our claims subject to the proceeding were not covered under the applicable policy and therefore we were not entitled to reimbursement of our $ 175 million claim against the applicable insurers.

With respect to our remaining $ 50 million claim against different insurance carriers, we now regard collection of those claims as being less than “probable.” As a result, we have written off the entire $ 225 million receivable and will recognize any future collections as and if they are received.

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 excluding future claims and lawsuits 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.

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 years ended December 31, 2023, 2022 and 2021, we recognized costs, net of amounts probable of recovery from insurance carriers, of $ 10 million, $ 95 million and $ 15 million, respectively.

During the years ended December 31, 2024, 2023 and 2022, we recognized costs, net of amounts probable of recovery from insurance (as applicable), of $ 345 million, $ 10 million, and $ 95 million, respectively.

As of December 31, 2024 and 2023, we had a remaining undiscounted gross liability of approximately $ 5 million and $ 94 million, respectively, related to the Line 901 incident, which aggregate amounts are reflected in “Current liabilities” on our Consolidated Balance Sheet.

As discussed above, we maintain insurance coverage, which is subject to certain exclusions and deductibles, in the event of such liabilities.

As of December 31, 2023, our incurred costs for the Line 901 incident have exceeded our insurance coverage limit of $ 500 million related to our 2015 insurance program applicable to the Line 901 incident by $ 250 million.

Through December 31, 2023, we had collected, subject to customary reservations, approximately $ 280 million out of the $ 505 million of release costs that we believe are probable of recovery from insurance carriers (including the 2015 insurance program and our directors and officers (D&O) insurance policies), net of deductibles.

Therefore, as of December 31, 2023, we have recognized a long-term receivable of approximately $ 225 million for the portion of the release costs that we believe is probable of recovery from insurance, net of deductibles and amounts already collected.

We anticipate that the process to enforce our coverage claims with respect to the Class Action Settlement will take time and, accordingly, have recognized such amount as a long-term asset in “Other assets” on our Consolidated Balance Sheet.

As of December 31, 2023, we had recognized a receivable of approximately $ 225 million for the portion of the release costs that we believed were probable of recovery from insurance, net of deductibles and amounts already collected (approximately $ 280 million out of the $ 505 million submitted, including the 2015 insurance program and our directors and officers (D&O) insurance policies).

Of this amount, we had classified $ 175 million as a short-term asset in “Trade accounts receivable and other receivables, net” with the remaining $ 50 million recognized as a long-term asset in “Other long-term assets, net” on our Consolidated Balance Sheet as of December 31, 2023.

Following the arbitration panel ruling discussed above, we wrote off the full $ 225 million insurance receivable in the fourth quarter of 2024.

Therefore, as of December 31, 2024, we no longer have any amounts recorded as receivables related to the Line 901 incident recognized on our Consolidated Balance Sheet.

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.

We believe the claims are without merit and that the outcome of the lawsuit will not have a material adverse effect on our financial condition, results of operations or cash flows.

We intend to vigorously defend against the claims asserted in this lawsuit.

We have entered into a confidential settlement agreement and anticipate that in connection with the settlement, all of Hartree’s claims will be dismissed with prejudice and without any admission of wrongdoing by Plains.

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 24 th 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 damages in an unspecified amount.

Our subsidiary owned and operated a pipeline in the vicinity of the refuge from 2006 through 2016.

The damages have not been quantified and are not yet reasonably estimable, but we believe the claims in the lawsuit lack merit and intend to vigorously defend this lawsuit in coordination with the other Defendants.

3 unchanged sentences

Our crude oil and NGL marketing activities are included in the respective reporting segments as their 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 each of our segments.

Our CODM (our Chief Executive Officer) evaluates segment performance based on measures including Segment Adjusted EBITDA (as defined below) and maintenance capital.

The measure of Segment Adjusted EBITDA forms the basis of our internal financial reporting and is the primary performance measure 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) purchases and related costs, (b) field operating costs and (c) segment general and administrative expenses, plus (d) our proportionate share of the depreciation and amortization expense (including write-downs related to cancelled projects and impairments) of unconsolidated entities, further adjusted (e) 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 (f) to exclude the portion of all preceding items that is attributable to noncontrolling interests in consolidated joint venture entities (“Segment amounts attributable to noncontrolling interests in consolidated joint ventures”).

Our CODM (our Chief Executive Officer) evaluates segment performance based on measures including Segment Adjusted EBITDA (as defined below).

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.
