Dear Fellow Plains Investors,

We are grateful for your investment in Plains, and we are pleased to invite you to join us for our May 24, 2023 annual meeting.

2022 represented a critical inflection point for Plains. We exited the year in a position of financial strength and well positioned to continue delivering strong operating and financial results. Throughout the year, we executed on our goals and initiatives in a dynamic macro environment.

Our integrated business model, flexible asset base and strong execution allowed us to capture increasing volumes from production growth and capitalize on commercial opportunities. As a result, we exceeded our financial guidance while also achieving record health, safety and environmental performance by meeting or exceeding 20% reduction targets in our key metrics. Overall achievements from 2022 include:

•

Delivered $2.51 billion in Adjusted EBITDA attributable to PAA and Implied Distributable Cash Flow per Common Unit and Common Unit Equivalent of $2.26, exceeding our initial February targets of $2.2 billion and $2.00, respectively;

•

Generated $1.61 billion in Free Cash Flow, returned approximately $658 million to common equity holders via distributions and unit repurchases, invested approximately $500 million of investment and maintenance capital, repaid $774 million of total debt and achieved a year-end leverage ratio (total debt/adjusted EBITDA) of 3.7x approximately one year earlier than originally planned;

•

Completed and/or announced several win-win strategic transactions, all of which further optimized our asset base and streamlined our operations; and

•

Announced multi-year capital allocation framework prioritizing Free Cash Flow generation, financial flexibility and targeting increasing return of capital to equity holders.

As we look ahead, we remain constructive on the long-term fundamentals that underpin our business and the need for North American energy, with recent events serving as a reminder that all forms of energy are needed to satisfy growing global energy demand. Underlying supply and demand fundamentals, together with realistic assumptions regarding the growth of various sources of energy, support our belief that hydrocarbons will remain an essential part of the world economy for decades to come. Energy from hydrocarbons will play a key role in supporting a growing global population, reducing poverty, extending longevity and improving overall quality of life.

With our network of strategically located North American midstream assets and our focus on the long-term positioning and optimization of our business, we believe we are very well positioned to play a critical role in the delivery of energy across North America and globally. As we do so, we will remain focused on generating meaningful multi-year free cash flow and maintaining a balanced approach to capital allocation that includes debt reduction and increasing returns of capital to equity holders through distribution increases and opportunistic repurchases. We believe the execution of our plan will deliver strong performance and enhanced value for our investors over the long term.

We appreciate your continued investment and support and we look forward to your participation in our 2023 annual meeting in May.

Sincerely,

Willie Chiang
Chairman of the Board & CEO

INFORMATION ABOUT THE PAGP AND PAA ANNUAL MEETINGS

PAGP will hold an annual meeting of its Class A, Class B and Class C shareholders (the “PAGP Annual Meeting”) immediately following the PAA Annual Meeting. At the PAGP Annual Meeting, PAGP shareholders will be asked to approve proposals 1, 2 and 3 described below. Each PAGP shareholder will be entitled to one vote for each Class A, Class B and Class C share owned for Proposals 1, 2 and 3. On March 27, 2023, 194,407,642 Class A shares, 46,594,786 Class B shares and 528,478,046 Class C shares were issued and outstanding. PAA owns all of the issued and outstanding Class C shares, which serve as a pass-through voting mechanism allowing eligible PAA Unitholders to vote indirectly at the PAGP Annual Meeting by instructing PAA how to vote the Class C shares on their behalf.

At the PAA Annual Meeting, PAA Unitholders (other than Plains AAP) will vote on a pass-through basis on proposals 1, 2 and 3 described below by instructing PAA how to vote the PAGP Class C shares that it owns on such proposals at the PAGP Annual Meeting. PAA will vote (or refrain from voting) the Class C shares at the PAGP Annual Meeting on behalf of and according to the direction of PAA’s Unitholders (excluding Plains AAP) with respect to proposals 1, 2 and 3.

See pages 9-11 for additional information with respect to our ownership and voting structure.

TABLE OF CONTENTS

QUESTIONS AND ANSWERS ABOUT THE PAA ANNUAL MEETING

The following questions and answers are intended to briefly address some commonly asked questions regarding the PAA Annual Meeting. These questions and answers may not address all questions that may be important to you as a Unitholder. Please refer to the additional information contained elsewhere in this proxy statement and the documents referred to in this proxy statement.

What is the purpose of these proxy materials?

The Board is soliciting your proxy to vote at the PAA Annual Meeting because you were a Unitholder at the close of business on March 27, 2023, the record date for the PAA Annual Meeting (the “Record Date”), and you are therefore entitled to receive notice regarding the PAA Annual Meeting, and to attend and vote at the PAA Annual Meeting. This proxy statement summarizes the information that you need to know in order to cast your vote at the PAA Annual Meeting. Your vote is very important and the Board strongly encourages you to exercise your right to vote. You do not need to attend the PAA Annual Meeting to vote your units, and we encourage you to vote even if you are unable to attend the PAA Annual Meeting in person. If you are unable to attend the PAA Annual Meeting in person, you may vote by Internet, by telephone or by signing and returning the attached proxy card in the envelope provided. See “How do I vote?” below.

What is the recommendation of the Board?

The Board unanimously recommends that you vote in the following manner:

•

FOR the election of each of Willie Chiang, Ellen DeSanctis, Alexandra Pruner and Lawrence Ziemba as a Class I director of the Board to serve until the 2026 annual meeting;

•

FOR the ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023; and

•

FOR the approval, on a non-binding advisory basis, of our 2022 named executive officer compensation.

When and where is the PAA Annual Meeting?

The PAA Annual Meeting will be held on May 24, 2023, at 10:00 a.m. Central Time, in the Texas Room located on the 19th Floor of Three Allen Center, 333 Clay Street, Houston, Texas 77002. Only Unitholders of record as of the close of business on March 27, 2023 are entitled to vote and ask questions at the PAA Annual Meeting. If you are not a Unitholder of record but hold units in “street name” through a brokerage firm, bank, dealer or other similar organization, trustee, or nominee (generally referred to in this proxy statement as a “broker”), you may attend the PAA Annual Meeting as a guest. Please note that if you hold units in “street name” through a broker and desire to vote your units or ask questions during the PAA Annual Meeting, you must request and obtain a valid “legal proxy” from your broker and register to attend the PAA Annual Meeting as a Unitholder with American Stock Transfer & Trust Company, LLC (“AST”).

Information on who can vote and ask questions during the PAA Annual Meeting is discussed immediately below.

Who can vote and ask questions at the PAA Annual Meeting?

You are entitled to vote and ask questions at the PAA Annual Meeting if you were a Unitholder of record as of the close of business on March 27, 2023, the Record Date for the PAA Annual Meeting.

Unitholder of Record: Units Registered in Your Name. You are a Unitholder of record if your units were registered directly in your name with our transfer agent, AST, at the close of business on March 27, 2023. As a Unitholder of record, you may vote and ask questions during the PAA Annual Meeting. Whether or not you plan to attend the PAA Annual Meeting, we urge you to submit a proxy to ensure your vote is counted. See page 4 for detailed instructions on how to vote your units.

TABLE OF CONTENTS

Beneficial Owner: Units Registered in the Name of Broker. If your units were held in an account at a broker at the close of business on March 27, 2023, then you are the beneficial owner of units held in “street name” and the broker holding your account is considered to be the Unitholder of record for purposes of voting at the PAA Annual Meeting. As a beneficial owner, you have the right to direct your broker regarding how to vote the units in your account. You are also invited to attend the PAA Annual Meeting as a guest. Because you are not the Unitholder of record, you may not vote your units or ask questions at the PAA Annual Meeting unless you request and obtain a valid legal proxy from the organization that holds your units giving you the right to vote the units and ask questions at the PAA Annual Meeting. Follow the instructions provided by your broker or bank, or contact your broker or bank to request a legal proxy form.

After obtaining a valid legal proxy from your broker, bank or other agent, in order to vote and ask questions at the PAA Annual Meeting, you must register to attend the PAA Annual Meeting as a Unitholder by submitting to AST proof of your legal proxy reflecting the number of your units along with your name and email address. Requests for registration should be directed to proxy@astfinancial.com or to facsimile number 718-765-8730. Written requests can be mailed to:

American Stock Transfer & Trust Company, LLC
Attn: Proxy Tabulation Department
6201 15th Avenue | Brooklyn, NY 11219

Requests for registration must be labeled as “Legal Proxy” and be received no later than 5:00 p.m., Eastern Time, on May 17, 2023.

You will receive a confirmation of your registration by email after we receive your registration materials. Once registered, you may attend the PAA Annual Meeting, submit questions and vote your units during the meeting.

Who is soliciting my proxy?

The Board is sending or otherwise providing you access to this proxy statement in connection with its solicitation of proxies for use at the PAA Annual Meeting.

Who is entitled to vote at the PAA Annual Meeting?

All holders of record of our common units and Series A preferred units as of the close of business on the Record Date are entitled to receive notice of the PAA Annual Meeting and to vote the common units and Series A preferred units that they held on the Record Date at the PAA Annual Meeting as described below.

Each common unitholder (other than Plains AAP) is entitled to one vote for each common unit owned on all matters to be considered at the PAA Annual Meeting. The Series A preferred unitholders will vote on an as-converted basis, with each Series A preferred unit entitled to one vote on all matters to be considered at the PAA Annual Meeting. As of March 27, 2023, 698,390,006 common units and 71,090,468 Series A preferred units were issued and outstanding. As of March 27, 2023, Plains AAP owned 241,002,428 common units, and, as noted above, it is not entitled to vote such common units on proposals 1, 2 or 3. The following table provides the number of common units entitled to vote on each proposal:

TABLE OF CONTENTS

	Proposal			Common Units Entitled to Vote (including Series A Preferred Units on an as-converted basis)			Explanation
	Proposals 1, 2 and 3			528,478,046			Excludes common units held by Plains AAP as of the Record Date. The number of common units owned by Plains AAP is, by design, equivalent to the number of outstanding PAGP Class A and Class B shares. PAGP Class A and Class B shareholders will vote on proposals 1, 2 and 3 directly at the PAGP Annual Meeting. Therefore, excluding common units held by Plains AAP from the “pass-through” vote prevents double voting on these proposals within the overall capital structure of PAGP, Plains AAP and PAA. See pages 9-11 for additional information regarding our ownership and voting structure.

How do I vote?

If you are a Unitholder of record at the close of business on the Record Date, you may vote your units by any of the following methods:

•

Voting online before the meeting. You may vote online by visiting the Internet address listed on your proxy card. Internet voting procedures have been established to verify your identity and to confirm your voting instructions. Please have your proxy card available when you visit the Internet address.

•

Voting by telephone before the meeting. You may vote by telephone by calling the toll-free number listed on your proxy card. Telephone voting procedures have been established to verify your identity, to allow you to provide proxy voting instructions and to confirm that your instructions were accurately recorded. Please have your proxy card available when you call.

•

Voting by mail before the meeting. You may vote by mail by returning your completed, signed and dated proxy card in the enclosed postage-paid return envelope. However, in order to ensure that your vote is received in a timely manner, we recommend that you vote online or by telephone as described above.

•

Voting during the meeting. If you were a Unitholder of record as of the close of business on the Record Date, you may attend the PAA Annual Meeting, ask questions and vote during the meeting. If you are a beneficial owner of units held in street name, you must be registered to attend the PAA Annual Meeting as a Unitholder and must have a valid legal proxy in order to ask questions and vote during the meeting. Please read the “Beneficial Owner: Units Registered in the Name of Broker” answer under the question “Who can vote and ask questions at the PAA Annual Meeting?” above for instructions on how to register to attend the PAA Annual Meeting and obtain a legal proxy.

Internet and telephone voting will be available to eligible Unitholders 24 hours a day until 11:59 p.m. Eastern Time on May 23, 2023, the night before the PAA Annual Meeting. If you use the Internet or the toll-free telephone number to provide your proxy voting instructions, you do not need to mail

TABLE OF CONTENTS

in your proxy card. If you mail in your proxy card, it must be received by PAA before the voting polls close at the PAA Annual Meeting.

Even if you plan to attend the PAA Annual Meeting, please vote your units by proxy in advance of the PAA Annual Meeting (either online, by telephone or by mail as described above) as soon as possible so that your units will be represented at the PAA Annual Meeting if for any reason you are unable to attend.

What do I do if I want to change my vote after I have already voted by proxy?

If you were a Unitholder of record as of the close of business on the Record Date, you may change your vote at any time before the voting polls close at the PAA Annual Meeting by:

•

submitting a proxy with new voting instructions using the Internet or telephone voting system (please note that the deadline for voting online or by telephone is 11:59 p.m. Eastern Time on May 23, 2023);

•

delivering a later-dated, executed proxy card or written notice of revocation of your proxy to American Stock Transfer & Trust Company, LLC, 6201 15th Avenue, Brooklyn, New York 11219 on or prior to the close of business on May 23, 2023; or

•

attending the PAA Annual Meeting and voting during the PAA Annual Meeting pursuant to the instructions above. Please note that attendance at the PAA Annual Meeting will not by itself (i.e., without also voting) revoke a previously granted proxy.

If you were a beneficial owner of common units held in street name as of the close of business on the Record Date and you have instructed your broker or other nominee to vote your units, you must follow the procedure your broker or other nominee provides to change those instructions. You may also vote during the PAA Annual Meeting if you obtain a legal proxy from your broker or other nominee and register to attend the PAA Annual Meeting pursuant to the instructions above.

What is a broker non-vote?

A broker non-vote occurs when units held by a broker, bank or other nominee on behalf of a beneficial owner are not voted with respect to a particular matter because the broker lacks discretionary authority to vote the units and has not received voting instructions from the beneficial owner. Brokers, banks and other nominees only have discretionary authority to vote on routine proposals; they are prohibited from voting on non-routine proposals without instructions from the beneficial owner. The ratification of the independent auditor (Proposal 2) is the only routine matter on which brokers, banks and other nominees may vote in their discretion on behalf of beneficial owners who have not provided voting instructions. The election of directors (Proposal 1) and the advisory vote to approve our 2022 named executive officer compensation (Proposal 3) are non-routine matters. If a broker returns a proxy with a voting choice selected for a routine proposal but with no voting choice selected for a non-routine proposal, the result is a broker non-vote. Broker non-votes are counted as present and entitled to vote for purposes of determining a quorum at the meeting, but are not considered votes cast and will have no impact on non-routine matters. Accordingly, we do not expect there to be any broker non-votes for Proposal 2 and broker non-votes will not be counted as votes either “FOR” or “AGAINST” Proposals 1 and 3.

What constitutes a quorum?

The holders of a majority of the outstanding common units and Series A preferred units (on an as-converted basis) entitled to vote and represented in person or by proxy, considered together, shall constitute a quorum at the PAA Annual Meeting. Your units will be counted as present (i.e., entitled to vote and represented in person or by proxy) at the PAA Annual Meeting if:

•

you are present and vote at the meeting; or

•

you, or your broker if you are a beneficial owner of units held in street name, have submitted a properly executed proxy.

TABLE OF CONTENTS

Executed proxies received but marked as abstentions and broker non-votes will be counted as present for purposes of determining the presence of a quorum.

What will I be voting on and what vote is required to approve the proposals discussed in this proxy statement?

Unitholders (other than Plains AAP) will be casting a “pass-through” vote on Proposals 1, 2 and 3 by instructing PAA how to vote its PAGP Class C shares on such proposals at PAGP’s annual meeting. PAA will vote (or refrain from voting) its Class C shares on each matter submitted to PAGP’s shareholders in the same proportion as the votes received from or withheld by the Unitholders with respect to such matter. The proposals that will be voted upon and the required vote for approval of such proposals is set forth in the following table:

Proposal

Voting Options

Vote Required for Approval of
Proposal at the
PAGP Annual Meeting

The election of four Class I directors to serve on the Board until the 2026 annual meeting.

You may vote “FOR”, or you may “WITHHOLD” authority to vote for, all, some or none of the nominees for director.

Directors will be elected by a plurality of the votes cast, in person or by proxy, by the holders of the Class A, Class B and Class C shares present and entitled to vote, voting as a single class. Broker non-votes are not considered votes cast and will have no effect on the election of directors.

The ratification of the appointment of PricewaterhouseCoopers LLP as PAGP’s and PAA’s independent registered public accounting firm for the fiscal year ending December 31, 2023.

You may vote “FOR” or “AGAINST” the proposal, or you may “ABSTAIN” from voting.

In order for this proposal to be approved, it must receive a majority of the votes cast, in person or by proxy, by the holders of the Class A, Class B and Class C shares present and entitled to vote, voting as a single class. Abstentions will be counted as votes present and entitled to vote and will have the same effect as votes “AGAINST” this proposal. We do not expect there to be any broker non-votes for this proposal.

The approval, on a non-binding advisory basis, of our 2022 named executive officer compensation.

You may vote “FOR” or “AGAINST” the proposal, or you may “ABSTAIN” from voting.

In order for this non-binding proposal to be approved, it must receive a majority of the votes cast, in person or by proxy, by the holders of the Class A, Class B and Class C shares present and entitled to vote, voting as a single class. Abstentions will be counted as votes present and entitled to vote and will have the same effect as votes “AGAINST” this proposal. Broker non-votes are not considered votes cast and will have no effect on the outcome of this proposal.

Who covers the expense of the proxy solicitation?

The expense of preparing, printing and mailing this proxy statement and the proxies solicited hereby will be borne by us. In addition to the use of the mail, proxies may be solicited by PAGP

TABLE OF CONTENTS

GP’s directors and officers, as well as by employees of GP LLC, without additional remuneration, by mail, phone, fax or in person. We will also request brokerage firms, banks, nominees, custodians and fiduciaries to forward proxy materials to the beneficial owners of our units as of the close of business on the Record Date and will provide reimbursement for the cost of forwarding the proxy materials in accordance with customary practice. Your cooperation in promptly voting your units electronically, via the Internet or by telephone, or by signing and returning the enclosed proxy card will help to avoid additional expenses. We have hired Georgeson LLC to solicit proxies for a fee of $10,500 plus reasonable expenses for additional services.

What if I do not mark a voting choice for some of the matters listed on my proxy card?

If you return a signed proxy card without indicating your voting choice, your units will be voted in accordance with the Board’s recommendation for each proposal with respect to which a voting choice is not indicated.

Who will tabulate and certify the vote?

AST will tabulate and certify the vote, and a representative of AST will act as the independent inspector of elections for the PAA Annual Meeting.

CORPORATE GOVERNANCE AND RELATED MATTERS

Summary of Recent Changes

Investors have voiced a preference for certain governance practices, and over the course of the last several years, our board and governance structure has evolved and changed in ways that we believe are meaningfully beneficial to investors. Highlights of some of the key changes are as follows:

2016

•

Replaced our dual board structure for PAA and PAGP with a unified governance structure that resulted in the Board being solely responsible for the governance of PAA and PAGP;

•

Amended our governing documents to enfranchise all shareholders of PAGP and all public common unitholders and Series A preferred unitholders of PAA by providing for shareholder elections of directors commencing in 2018 (on a staggered three-year rolling basis);

2017

•

Added Asian American director to the Board (subsequently became Chairman of the Board in January 2020);

2018

•

Held first annual meeting for the election of directors;

•

Added new independent female director to the Board;

2019

•

Amended our governing documents to require that a majority of our Board satisfy applicable stock exchange independence requirements, despite the fact that as a limited partnership we are exempt from such requirements (nine out of 12 (75%) of our current Board members have been assessed by the Board and determined to be independent);

•

Amended our governing documents to create a strong lead independent director role in connection with the retirement of our former Chairman and the re-combination of the roles of Chairman and CEO;

•

With the assistance of our Governance Committee, initiated a comprehensive board assessment, refreshment and succession planning process that includes a periodic skills and needs assessment, the development and maintenance of a formal board succession plan and annual director performance evaluations;

2020

•

Added new independent director to the Board;

•

Appointed independent chairman to Compensation Committee;

•

Adopted Equity Ownership Guidelines and Clawback Policy;

2021

•

Established a new committee, the Health, Safety, Environmental and Sustainability (“HSES”) Committee, to assist the Board in its oversight of various HSES matters and facilitate the efforts of management to further strengthen our focus on sustainability and ESG matters;

•

Mandated that the members of all Board committees be independent;

•

Amended our governing documents to increase the number of directors subject to public election by adding the three directors who are current or former members of management;

•

Amended our governing documents to eliminate the lone remaining legacy director designation right, resulting in all Board members being subject to public election, and all non-management directors serving on the same basis in terms of rights, duties and obligations of directors; and

TABLE OF CONTENTS

2022

•

Added new independent female director to the Board.

As described in the summary above, since 2016, the Board has taken numerous meaningful steps to provide PAGP shareholders and PAA unitholders the right to vote for members of the Board. At a special meeting of PAGP shareholders held in November 2016 in connection with our simplification transaction (the “Simplification Transaction”), PAGP shareholders overwhelmingly approved the following changes to our governing documents, among others:

•

the implementation of a unified governance structure for PAA and PAGP that resulted in the Board being solely responsible for the governance of PAGP and PAA; and

•

the division of the Board into three classes and the commencement of director elections by class starting in 2018, with the participation and enfranchisement of all shareholders of PAGP and all public common unitholders and Series A preferred unitholders of PAA.

These features distinguish us from many of our midstream master limited partnership peers. Together with the alignment of interests among investors that was created through the elimination of PAA’s incentive distribution rights in connection with the Simplification Transaction, the Board has put in place an overall governance structure that vastly improves the governance rights of our investors and which we believe is regarded by many as a structure that, together with other factors, produces a degree of alignment with our investors that places us at the top of our master limited partnership peers for the midstream sector regarding governance structure and voting rights. The Board believes that the continued implementation of the modified governance structure as approved by PAGP’s shareholders, together with the governance enhancements made in recent years, is consistent with the desires and expectations of investors in PAA and PAGP.

Our Management and Governance

Our operations and activities are managed by GP LLC, which employs our management and operational personnel (other than our Canadian personnel, who are employed by Plains Midstream Canada ULC). GP LLC is the general partner of Plains AAP, which is the sole member of our general partner. PAGP is the sole member of GP LLC, and PAGP GP is the general partner of PAGP. PAGP does not directly own any operating assets or have any operating activities apart from those conducted by PAA. The Board of PAGP GP has responsibility for managing the business and affairs of PAGP and PAA.

Our Unitholders are limited partners and do not directly or indirectly participate in our management or operation. Unlike holders of common stock in a corporation, our Unitholders have only limited voting rights on matters affecting our business or governance, subject in all cases to any specific unitholder rights contained in our partnership agreement. In connection with the Simplification Transaction completed in November 2016, we expanded the voting rights of our Unitholders to include the election of directors and, in 2018, we began holding annual meetings for this purpose.

Our Ownership and Voting Structure

The Simplification Transaction completed in November 2016 resulted in a structure that includes two public companies (PAA and PAGP) governed by a single Board. The Board is located at PAGP’s general partner, PAGP GP. The Simplification Transaction also provided that the equity holders of both PAA and PAGP would be afforded the right to vote in the election of directors.

PAGP has three classes of voting equity, as follows:

•

PAGP Class A shares, which are listed on Nasdaq;

•

PAGP Class B shares, which represent non-economic limited partner voting interests and are privately held by certain legacy investors and management; and

•

PAGP Class C shares, which are also non-economic limited partner voting interests. The PAGP Class C shares are held by PAA solely for the purpose of creating a mechanism through which PAA equity holders (other than Plains AAP) can participate in the election of directors of PAGP GP.

TABLE OF CONTENTS

With respect to the election of directors, the PAGP Class A, Class B and Class C shares vote together as a single class. PAGP equity holders vote directly at the PAGP Annual Meeting. PAA equity holders (which include holders of PAA’s publicly held Common units and Series A preferred units) vote indirectly by instructing PAA how to vote the Class C shares that it owns on their behalf at the PAGP Annual Meeting. In order to receive voting instructions from PAA voting equity holders, PAA holds its annual meeting immediately prior to the PAGP Annual Meeting. The voting instructions received at the PAA annual meeting are “passed through” by PAA by virtue of its voting of the Class C shares at the PAGP Annual Meeting in accordance with such instructions.

On a combined basis, as of the Record Date, the voting rights of PAGP and PAA equity holders in connection with the election of directors were allocated as follows:

Board Leadership

Mr. Chiang serves as Chairman of the Board and as CEO, and Mr. Shackouls serves as Lead Director. Our governing documents require that for so long as the Board Chair and CEO roles are held by the same person, one of our independent directors must serve as the Lead Director, and such governing documents also clearly delineate the respective responsibilities of the Board Chair and the Lead Director. The Lead Director is responsible for, among other things, developing and communicating the agenda for, and presiding at, meetings of the non-management directors, collaborating with the Board Chair on Board meeting agendas, working with the Board Chair to establish parameters for the quality, amount and timeliness of the information flow between management and the Board, and generally acting as a liaison between the non-management directors and the Board Chair. The Board has no set policy with respect to the separation of the offices of Board Chair and CEO; rather the Board believes it is in the best interests of PAA and PAGP for the Board to review ongoing conditions and circumstances and make an appropriate determination to separate, or maintain as combined, the CEO and Board Chair roles at the time a new CEO succeeds the current CEO, or upon a significant change in circumstances. The Board Chair/CEO regularly communicates with the Lead Director to make sure the Board is receiving the information it needs and has the opportunity to provide feedback and input to management, in each case as required for the Board to discharge its oversight role.

Board Role in Risk Oversight

With respect to the management of enterprise-level risk (ELR), which is the process of identifying, managing and monitoring events that present opportunities and risks with respect to the operation of our business and the creation of value for our unitholders, the Board has delegated primary responsibility to management while retaining oversight responsibility. Management provides a formal ELR assessment to the Board at least once every year and provides updates on other areas of potential risk on at least a quarterly basis.

We believe that our Board leadership and committee structure supports the Board’s risk oversight function by facilitating open and regular communication between management and the directors, which allows informed oversight of management’s processes for identifying and managing significant risks

TABLE OF CONTENTS

and their impact on PAA’s business. The Board’s various committees (Audit, Governance, Compensation and HSES) assist the Board with respect to its oversight of risks related to the specific areas of focus for each committee.

Non-Management Executive Sessions and Shareholder Communications

Non-management directors meet in executive session in connection with each regular Board meeting. These sessions are presided over by the Lead Director. As circumstances warrant, non-management directors may also meet in executive sessions of special meetings of the Board.

Interested Unitholders can communicate with non-management directors regarding PAA’s business and affairs by mail in care of the General Counsel and Secretary or in care of the Vice President of Internal Audit at Plains All American Pipeline, L.P., 333 Clay Street, Suite 1600, Houston, Texas 77002. Commercial solicitations or communications will be disregarded.

Independence Determinations

Because we are a limited partnership, the listing standards of Nasdaq do not require that we or our general partner have a majority of independent directors on the Board. Nonetheless, the PAGP GP LLC Agreement was amended in 2019 to require that our Board have a majority of directors who are independent as defined in applicable Nasdaq and SEC rules. To be considered independent under Nasdaq listing standards, our Board must determine that a director has no relationship with us that would interfere with the exercise of independent judgement in carrying out his or her responsibilities as a director. The applicable Nasdaq and SEC rules specify the criteria by which the independence of directors must be determined, including guidelines for directors and their immediate family members with respect to employment or affiliation with us or with our independent public accountants. The Board has assessed the independence of the nine directors who are not current or former members of management (Messrs. Burk, McCarthy, Petersen, Raymond, Shackouls, Temple and Ziemba, Ms. DeSanctis and Ms. Pruner) and has concluded that all of such directors are independent under applicable Nasdaq and SEC standards.

Audit Committee

Our Audit Committee reviews our external financial reporting, engages our independent auditors, and reviews the adequacy of our internal accounting controls. The charter of our Audit Committee is available on our website. See “— Meetings and Other Information” for information on how to access or obtain copies of this charter. The Board has determined that each member of our Audit Committee (Messrs. Burk (chair) and Ziemba, Ms. DeSanctis and Ms. Pruner) is (i) independent under applicable Nasdaq and SEC rules, and (ii) financially literate. The Board has also determined that each of Mr. Burk and Ms. Pruner qualifies as an Audit Committee Financial Expert as that term is defined in Item 407 of Regulation S-K.

Compensation Committee; Compensation Committee Interlocks and Insider Participation

Although not required by Nasdaq listing standards, we have a Compensation Committee that reviews and makes recommendations to the Board regarding the compensation for our executive officers and administers our long-term equity incentive plans for officers and key employees. The Compensation Committee has delegated limited authority to the CEO to administer our long-term incentive plans with respect to employees and non-Section 16 officers below the Senior Vice President level. The charter of our Compensation Committee is available on our website. See “— Meetings and Other Information” for information on how to access or obtain copies of this charter. The Compensation Committee currently consists of Messrs. Raymond (chair), Petersen and Temple. Under applicable Nasdaq rules, none of the members of our Compensation Committee are required to be independent; however, the charter of our Compensation Committee requires that all members of the committee be independent and the Board has determined that all of the current members of the Compensation Committee are independent under applicable Nasdaq and SEC standards. The Compensation Committee has the sole authority to retain any compensation consultants to assist the committee. Since 2019, the Compensation Committee

TABLE OF CONTENTS

has engaged Meridian Compensation Partners, LLC (“Meridian”) to conduct independent annual reviews and benchmark studies of our executive compensation program and practices.

During 2022, none of the members of the Compensation Committee was an officer or employee of ours or any of our subsidiaries, or served as an officer of any company with respect to which any of our executive officers served on such company’s board of directors. In addition, none of the members of the Compensation Committee are former employees of ours or any of our subsidiaries. Mr. Raymond is associated with The Energy & Minerals Group (“EMG”) and Mr. Petersen is associated with EnCap Investments LP (“EnCap”). We have ordinary course business relationships with entities affiliated with EMG and EnCap; however, the Board has determined that these relationships do not impact Mr. Raymond’s or Mr. Petersen’s independence. See “Certain Relationships and Related Transactions.”

Governance Committee

Although not required by Nasdaq listing standards, we also have a Governance Committee that periodically reviews our governance structure, policies and principles, oversees the Board’s annual self-assessment and committee evaluation process, and assists with succession planning and other governance-related activities, including identifying and assessing director nominees. See “Proposal 1 — Election of Class I Directors — Director and Nominee Experience and Qualifications” for additional information regarding activities of our Governance Committee. The charter of our Governance Committee is available on our website. See “— Meetings and Other Information” for information on how to access or obtain copies of this charter. The Governance Committee currently consists of Messrs. Shackouls (chair), McCarthy and Petersen and Ms. Pruner. Under applicable Nasdaq rules, none of the members of our Governance Committee are required to be independent; however, the charter of our Governance Committee requires that all members of the committee be independent and the Board has determined that all of the current members of the Governance Committee are independent under applicable Nasdaq and SEC standards.

HSES Committee

In February 2021, the Board established the HSES Committee to assist the Board in its evaluation and oversight of our (i) management of HSES matters, including compliance with applicable laws and regulations; (ii) management of systems and plans to protect the health and safety of employees, contractors, customers, the environment, the communities where we operate, our assets, and our reputation; and (iii) plans to adjust to HSES trends and related risks to more effectively achieve our long-term business and sustainability objectives. Through the discharge of its oversight responsibilities, the HSES Committee facilitates the efforts of management to further strengthen our focus on sustainability and ESG matters. The charter of our HSES Committee is available on our website. See “— Meetings and Other Information” for information on how to access or obtain copies of this charter. The HSES Committee currently consists of Messrs. Ziemba (chair) and Temple and Ms. DeSanctis. The Board has determined that all of the current members of the HSES Committee are independent under applicable Nasdaq and SEC standards.

Meetings and Other Information

During 2022, our Board had six meetings, our Audit Committee had ten meetings, our Compensation Committee had two meetings, our Governance Committee had one meeting and our HSES Committee had six meetings. In addition, members of our Compensation Committee and Governance Committee held numerous conference calls and discussions throughout the year on various compensation and governance-related matters. All directors have access to members of management, and a substantial amount of information transfer and informal communication occurs between meetings. In 2022, all of our directors attended all meetings of the Board and applicable committees of the Board on which the director served, other than two directors who each missed one Board meeting, and another director who missed one committee meeting. Board members are encouraged, but not required, to attend our annual meetings; five Board members attended our annual meeting in 2022.

All of our standing committees have charters. Our committee charters and governance guidelines, as well as our Code of Business Conduct (which describes our Core Values) and our Code of Ethics

TABLE OF CONTENTS

for Senior Financial Officers (which applies to our principal executive officer, principal financial officer and principal accounting officer), are available under the Structure and Governance tab in the Investor Relations section of our Internet website at http://www.plains.com. We intend to disclose any amendment to or waiver of the Code of Ethics for Senior Financial Officers and any waiver of our Code of Business Conduct on behalf of an executive officer or director either on our Internet website or in an 8-K filing. We regularly post important information on our website, including information regarding our sustainability efforts.

Conflicts Committee/Fiduciary Duties

Our partnership agreement allows for the establishment or activation of a conflicts committee as circumstances warrant to review conflicts of interest between us and our general partner or its owners. Such committee will typically consist of a minimum of two independent, non-employee members of the Board. Our partnership agreement provides that any matters approved by the conflicts committee will be conclusively deemed to be fair and reasonable to us, approved by all of our partners, and not a breach by our general partner of any duties owed to us or our Unitholders. See “Certain Relationships and Related Transactions — Review, Approval or Ratification of Transactions with Related Persons.”

Our partnership agreement limits any fiduciary duties our general partner might owe to our Unitholders. Our general partner is liable for all of our debts (to the extent not paid from our assets), except for indebtedness or other obligations that are made specifically non-recourse to it. Our general partner has the sole discretion to incur indebtedness or other obligations on our behalf on a non-recourse basis to the general partner. Our general partner has in the past exercised such discretion, in most instances involving payment liability, and may exercise such discretion again in the future.

PROPOSAL 1 — ELECTION OF CLASS I DIRECTORS

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE ELECTION OF EACH OF WILLIE CHIANG, ELLEN DESANCTIS, ALEXANDRA PRUNER AND LAWRENCE ZIEMBA TO SERVE AS A CLASS I DIRECTOR ON OUR GENERAL PARTNER’S BOARD OF DIRECTORS UNTIL THE 2026 ANNUAL MEETING.

Board Structure

General Overview and Board Makeup. Our Board has responsibility for managing the business and affairs of PAGP and PAA. The Board currently has 12 members, including the CEO, who currently serves as Chairman of the Board. As contemplated by our governing documents, because the roles of CEO and Board Chair are held by the same person, the Board has designated one of our independent directors (Bobby Shackouls) to serve as Lead Director. Our governing documents also require that at least a majority of directors must meet the independence requirements of the national securities exchange on which the securities of PAA and PAGP are listed (currently Nasdaq).

The Board is divided into three staggered classes such that the terms for the directors within each class expire on a rotating three-year basis, as set forth below. The Board (excluding directors whose terms are expiring) and, subject to certain ownership and notice requirements, holders of common units have the right to nominate individuals to stand for election at an annual meeting. For a description of such ownership and notice requirements, see “Director Nominations and Unitholder Proposals for the 2024 Annual Meeting” on page 78.

Individuals elected at an annual meeting will serve for a term of three years, subject to their earlier resignation, death or removal. If an individual is elected to the Board to fill a vacancy, that director will have the same remaining term as his or her predecessor. All directors standing for election at the PAA and PAGP Annual Meetings were nominated by the Board (excluding the vote of the directors whose terms are expiring); to our knowledge, no holder of our common units met the required ownership threshold and thus no nominations were received from holders of our common units.

Director and Nominee Experience and Qualifications

With respect to any director nominations made by the Board in connection with annual director elections or in the event of a vacancy on the Board, in each case to the extent requested by the Chairman of the Board, the Governance Committee assists in identifying and screening potential candidates. The Governance Committee makes its recommendations based on an assessment of the skills, experience and characteristics of the candidate in the context of the needs of the Board. It is the policy and practice of the Governance Committee and the Board to consider diversity (including diversity of gender, race and ethnicity) in connection with the process of identifying and assessing potential Board candidates.

Our board assessment, refreshment and succession planning process involves (i) the periodic assessment of the skills, background and experience of our directors, which is used to identify potential enhancement areas relative to the ideal mix of skills, background and experience for our board, (ii) the development and maintenance of a board succession plan that identifies near and longer-term actions and includes succession plans for each board committee, and (iii) the annual evaluation by each director of the performance of every other director in a variety of categories that directly impact overall board performance and effectiveness. Board succession planning efforts and director evaluations are updated on a regular basis with assistance and oversight of the Governance Committee. The Governance Committee also oversees the Board’s annual self-assessment process as well as the process by which the Board assesses the effectiveness of its various committees.

In evaluating director nominees and in reviewing the qualifications and experience of the directors continuing in office, the Governance Committee and Board consider a variety of factors, including independence, financial literacy, personal and professional accomplishments, diversity and experience in light of the needs of the Board. For incumbent directors, factors also include past performance on the Board. The Board has determined that it is beneficial to have individuals on the Board with the following skills, experiences, and characteristics (See the Director Skills Matrix below for an overview of the skills, experiences and characteristics of our current Board members):

EXECUTIVE COMPENSATION

Compensation Committee Report

The Compensation Committee reviews and makes recommendations to the Board regarding the compensation for our executive officers and directors. In fulfilling its oversight responsibilities, the Compensation Committee reviewed and discussed the following Compensation Discussion and Analysis (sometimes referred to as “CD&A”) with management and, based on such review and discussion, has recommended to the Board that the Compensation Discussion and Analysis be included in this proxy statement.

John T. Raymond, Chair
Gary R. Petersen
Christopher M. Temple

Compensation Discussion and Analysis

For 2022, our Named Executive Officers (sometimes referred to as “NEOs”) include our CEO, our President, our CFO, and the three most highly compensated executive officers (other than our CEO and CFO). Our NEOs for 2022 include the following individuals:

		Named Executive Officer				Title
		Willie Chiang				Chairman and Chief Executive Officer
		Harry Pefanis				President
		Al Swanson				EVP and Chief Financial Officer
		Richard McGee				EVP, General Counsel and Secretary
		Chris Chandler				EVP and Chief Operating Officer
		Jeremy Goebel				EVP and Chief Commercial Officer

2022 Executive Compensation Highlights

The discussion set forth below in this Compensation Discussion and Analysis describes our current approach to executive compensation and elaborates upon the various actions taken and adjustments made with respect to our executive compensation program. Highlights for 2022 include the following:

•

Continued Investor Engagement: During 2022, we continued our practice of engaging with our unitholders regarding key executive compensation issues and incorporating their feedback into the decisions we make. For example, with respect to key actions taken during 2022 regarding adjustments to the annual compensation elements for our NEOs and certain long term incentive plan matters, we incorporated feedback received from our investors during our 2021 engagement effort (for more information, see sections below titled “Unitholder Engagement,” “2022 Independent Benchmark Study of Executive Compensation” and “Adjustment of Certain Pre-Pandemic Long Term Incentive Awards”).

•

Adjustments to Annual Compensation Elements: In order to enhance retention and the competitive positioning of our NEO compensation relative to peers, and taking updated benchmark studies and individual situations into account, base salaries and other compensation elements for our NEOs were adjusted in February 2022. The goal of these adjustments was to enhance our competitiveness with respect to compensation and achieve what we believe are appropriate total compensation levels based on updated benchmark studies.

•

Annual Bonus: Due to above-target financial and safety/environmental performance in 2022, NEO bonuses paid out above target, with our CEO earning a bonus at 180% of target and our other NEOs earning bonuses at 184% of target on average.

TABLE OF CONTENTS

•

Long-Term Incentive Matters: We granted equity incentives to our NEOs, 50% in the form of time-based units and 50% in the form of performance-based units that can be earned based upon TSR and DCF results over a cumulative three-year performance period. In addition, after considerable and careful consultation with our unitholders as a part of our investor engagement effort during 2021, we adjusted the performance metric under two special long-term incentive/retention grants that were issued prior to the COVID-19 pandemic to our COO and CCO. See “Adjustment of Certain Pre-Pandemic Long Term Incentive Awards” for more details.

Executive Compensation General Philosophy and Approach

Our executive compensation philosophy emphasizes pay for performance, at both an individual and entity level, and places a significant portion of each Named Executive Officer’s compensation at risk. We believe this approach aligns the interests of our executive officers with the interests of our equity holders and at the same time allows us to attract, motivate and retain key executives. The table below highlights some of the key features of our executive compensation program:

		What We Do				What We Don’t Do
		✓ We emphasize pay for performance ✓ Our compensation program is structured to emphasize variable, at-risk compensation (over 80% of target NEO compensation is at risk) ✓ Our annual bonus program is 100% performance based with payout based on a formulaic framework ✓ 50% of NEO long-term equity incentives are performance based, requiring performance over a multi-year period ✓ Compensation program design mitigates against excessive risk taking ✓ Independent compensation consultant ✓ Regular investor engagement on compensation and other matters ✓ Equity Ownership Guidelines for executive officers and directors ✓ Clawback Policy that applies to performance based cash and equity compensation				No guaranteed bonuses No excise tax gross ups Directors and officers are prohibited from hedging or pledging company securities Our equity plan prohibits backdating or repricing of options No significant perquisites for our executive officers No single-trigger change in control protections in our long-term incentive plan grants

Unitholder Engagement

98% Say on Pay
Support in 2022

At our last annual meeting, over 98% of our voting equity holders approved our executive compensation program. Although this “say on pay” vote is advisory and non-binding, our Compensation Committee and Board value the opinions of our unitholders and carefully consider the results of “say on pay” votes and direct feedback received from investors, among a variety of other factors, when making future compensation decisions for our Named Executive Officers.

Our investor relations team and members of our senior management team regularly meet with investors and other stakeholders to seek input and feedback on a wide range of topics, including executive compensation. On an annual basis, as part of our ongoing investor outreach and engagement process, we actively solicit feedback from investors regarding our executive compensation programs

TABLE OF CONTENTS

and other important matters, including our evolving governance practices and sustainability efforts. In connection with this process during 2022, we reached out to 21 of our largest unaffiliated investors representing, as of December 31, 2022, approximately 37% of our outstanding voting equity (excluding executive officers and Directors who collectively hold approximately 10% of our outstanding voting equity). Members of our executive and investor relations teams ultimately held individual meetings with 15 unaffiliated investors representing approximately 29% of our outstanding voting equity.

Outreach to 21
Largest
Shareholders in
2022

The series of engagement meetings we held during 2021 and 2022 are a good example of what we refer to as the “feedback loop” that we have developed with our investors regarding our executive compensation program. During our 2021 engagement meetings, we previewed and sought advance feedback from our investors on two key areas of focus at that time for our Compensation Committee, namely:

(i)

the need to make adjustments to our NEOs’ annual compensation elements to achieve or maintain competitive compensation levels given that such pay had not been adjusted for several years, and

(ii)

the need to identify the most “investor friendly” way to restore an appropriate level of incentive and retentive value to the performance-based portion of certain special, long-term (seven year) equity grants issued to certain NEOs prior to the COVID-19 pandemic (the “Special Pre-Pandemic Grants”).

The Compensation Committee focused on the Special Pre-Pandemic Grants because the performance metrics for such grants were based on pre-pandemic forecasts and had been rendered effectively unachievable as a result of the impact of the pandemic on the midstream industry generally and Plains’ business specifically. Taking into account the feedback received from our investors on both of these topics during our 2021 engagement meetings, in early 2022, the Compensation Committee recommended, and the Board approved:

(i)

adjustments to our NEOs’ 2022 target annual compensation opportunities, as further described herein, based on an updated benchmark compensation study prepared by Meridian, targeting more appropriately competitive compensation, including 50th percentile compensation for the CEO, and

(ii)

changing the performance metric under the Special Pre-Pandemic Grants issued in 2019 to the COO and CCO to a total shareholder return (“TSR”) metric with a payout structure capped at 100% (See “Adjustment of Certain Pre-Pandemic Long-Term Incentive Awards” for more information).

To complete the “feedback loop” on these issues, during our 2022 engagement meetings, we reported back to our investors on the specific actions that had been taken by the Compensation Committee with respect to each issue, recapping for them the prior discussions we had, the rationale for the changes, and the manner in which their feedback had been incorporated. As we strive for continuous improvement, we believe that receiving and incorporating investor feedback into our decision-making process through this “feedback loop” is critical.

Overall, the design of our 2022 executive compensation program did not materially change relative to 2021, other than market-based adjustments to elements of NEO compensation. Investor feedback gathered during 2022 was supportive of our 2022 program and of the changes implemented in response to feedback gathered during our 2019 - 2021 investor outreach effort. The Compensation Committee and our management team are constantly reviewing the design of our programs to ensure that they remain aligned with investor interests and evolving best practices. We will continue to seek direct input from our investors as part of that process. The table below summarizes the key feedback we have received from our investors over the past several years and the changes we made to our executive compensation program in response to such feedback and related considerations:

TABLE OF CONTENTS

		What We Heard				What We Did
		No concerns with periodic adjustments to annual compensation elements for executive officers to maintain competitive pay as long as adjustments are based on appropriate compensation benchmark studies.				Implemented adjustments to annual compensation elements for our executive officers for first time in several years in order to improve competitive positioning relative to peers; adjustments were based on benchmark study prepared by Compensation Committee’s independent consultant, Meridian. Compensation Committee also indicated it would consider adjustments on a more frequent basis (i.e., annually or biennially) in order to avoid “lumpy” changes associated with less frequent adjustments.
		With respect to the issue of the loss of retentive and incentive value of the performance portion of the Special Pre-Pandemic Grants, (i) general understanding of and appreciation for the need to restore an appropriate level of retentive and incentive value to such awards, coupled with (ii) a strong preference for doing so in a manner that aligns the interests of the recipients with investor interests going forward and does not allow the recipients to “claw-back” or recover value degradation equivalent to that experienced by unitholders during the period between the original grant date and the date of any changes.				After carefully considering alternatives and taking investor feedback into account, the Board and Compensation Committee changed the performance metric under the Special Pre-Pandemic Grants issued in 2019 to the COO and CCO to a TSR metric with a payout structure that caps the maximum potential payout at 100% of the number of performance units that could have been earned under the original grants. The Board and Compensation Committee regarded this approach as the best way to restore an appropriate level of incentive and retentive value while ensuring investor alignment going forward and making sure that the value of any performance units earned would reflect the same value degradation experienced by unitholders since the original grant date. (See “Adjustment of Certain Pre-Pandemic Long-Term Incentive Awards” for more information). Nevertheless, no changes were made to the 2018 CEO promotion award in 2022, which was consistent with the desires of our CEO.
		Concern that DCF/CUE performance metric in long-term equity incentive awards did not require performance throughout the three-year vesting period and allowed too long of a period (4 years) to achieve target.				Beginning in 2020, the DCF/CUE performance metric in our long-term equity incentive awards requires performance over a full 12-quarter period vs. any trailing 4-quarter period, and the performance period is three years vs. four years.
		Concern that DCF/CUE performance metric in long-term equity incentive awards could incentivize management to inappropriately increase leverage to meet targets.				Beginning in 2020, our long-term equity incentive awards include a leverage modifier to mitigate this concern. Payout on cumulative three-year DCF/CUE performance metric in the 2020 and 2021 awards is subject to increase or decrease based on comparison of leverage ratio at end of three-year measurement period to the target leverage ratio established at time of grant. Payout on the DCF/CUE performance metric in the 2022 awards is subject to decrease if our leverage ratio (as defined in the LTIP grant agreements) at the end of the three-year measurement period exceeds 3.5x.
		Investor desire for use of a relative, returns-based performance metric in our equity incentive program.				Beginning in 2020 and continuing since then, our regular annual long-term equity incentive awards have included a relative TSR metric with an absolute TSR modifier.

TABLE OF CONTENTS

Our Commitment to Pay for Performance

Our executive compensation philosophy is focused on a long-term pay for performance culture designed to attract and retain key management talent in a competitive industry and market. Our program combines relatively low base pay (as a percentage of total rewards) with higher variable, at-risk compensation opportunities based on objective and transparent performance requirements. As demonstrated in the graphic below, in 2022, at target, approximately 89% of our CEO’s compensation and approximately 82% of our other NEOs’ compensation consisted of at-risk compensation.

Majority of NEO Pay At-Risk and Performance-Based

The “Other NEOs” graphic excludes Mr. Pefanis. Mr. Pefanis is a co-founder and substantial equity owner and for the last several years has requested to not participate in the long-term incentive program, which results in an at-risk compensation percentage for Mr. Pefanis of 67%.

At-risk compensation is typically tied to the achievement of one or more performance metrics that measure value creation over both the near and longer term, as well as service period requirements. The primary short-term financial metrics are annual earnings and cash flow levels as represented by Adjusted EBITDA1 attributable to PAA and distributable cash flow (“DCF”) per common unit equivalent (“CUE”). The primary long-term performance measures included in our equity incentive grants are DCF per CUE over a 3-year period (with a leverage modifier) and relative TSR over a 3-year period. We believe our short- and long-term performance metrics are consistent with our overall financial strategy of reducing our leverage and generating attractive unitholder returns.

We believe our pay-for-performance approach aligns the interests of our executive officers with the interests of our equity holders. We also believe that our pay-for-performance approach helps us achieve the overall objectives of our executive compensation program, which are to:

Earnings before interest, taxes, depreciation and amortization (including our proportionate share of depreciation and amortization, including write-downs related to canceled projects and impairments, of unconsolidated entities), gains and losses on asset sales and asset impairments, goodwill impairment losses and gains or losses on and impairments of investments in unconsolidated entities, adjusted for certain selected items impacting comparability.

Compensation Elements and Objectives

We use three primary elements of compensation in combination with competitive benefits to achieve our executive compensation program objectives — salary, annual cash incentive awards and long-term equity incentive awards. Our mix of compensation elements is designed to reinforce near-term and long-term business and strategic objectives, recognize and reward performance, motivate long-term value creation and align the interests of our executives with those of our equity holders.

2022 Independent Benchmark Study of Executive Compensation

With respect to our 2022 executive compensation program, our Compensation Committee engaged Meridian to provide independent counsel, including a benchmarking review of our executive officer compensation. In connection with its engagement of Meridian, the Compensation Committee evaluated and confirmed Meridian’s independence relative to existing PAA or PAGP relationships or potential conflicts, in line with Nasdaq requirements.

Business consolidation and unique operating models create some challenges in identifying directly comparable peer companies. Accordingly, we take a broad view of comparability to include organizations that are similar to ours and that we believe we compete with for attracting and retaining executive talent. Our compensation benchmarking peer group for 2022 included 11 companies across a wide range of revenues, asset values and enterprise values that are primarily engaged in the midstream business in the United States (the entities in the benchmarking peer group are listed in the table below).

Meridian utilized publicly available information to analyze compensation practices of the companies in the benchmarking peer group, including how pay is divided among long-term incentives, annual incentives, base pay and other forms of compensation. Meridian also compared the amount and structure of compensation for our executive officers to the benchmarking peer group. Meridian’s benchmark study was first completed and presented to the Compensation Committee in August 2021 and subsequently discussed and reviewed by the Compensation Committee in December 2021 and February 2022.

The Compensation Committee also considered similar information from a broader sample of companies in the energy sector, including upstream, refining and regulated utilities, although the benchmarking peer group listed in the table below served as the primary source of external comparative information.

The results of Meridian’s study validated our view that our 2021 NEO base salary and long-term incentive target levels were significantly lower than the median of our peer group and that each component of our CEO’s 2021 compensation was at or significantly below median, with total CEO compensation falling at approximately the 25th percentile.

In response to these study results and considering individual situations and investor feedback, the Compensation Committee recommended, and the Board approved, increases to NEO base salaries and adjustments to other elements of our executive compensation program in February 2022. In August 2022, the Compensation Committee had Meridian prepare an updated executive compensation benchmark study. As confirmed by Meridian’s August 2022 benchmark study, the 2022 NEO compensation adjustments resulted in the following:

•

Total target compensation for all NEOs on average falls within the middle range of our peers; and

•

Total target compensation for the CEO ranks slightly below median relative to peers.

For a portion (25%) of the long-term incentive awards granted to our executive officers in 2022, we included relative TSR as a performance metric for the three-year performance period ending June 30, 2025. The entities in our 2022 compensation benchmarking peer group and the entities and indices in our TSR Comparator Peer Group for the 2022 long-term incentive awards include the following:

Additional Information Regarding Compensation Practices and Processes

Set forth below is additional information regarding our compensation practices and processes as they relate to the elements of our compensation program:

Base Salary. Historically, we have not made regular annual adjustments to the base salaries of our Named Executive Officers (prior to 2022, the most recent across the board adjustments were made in 2017), but we have made salary adjustments in connection with promotions or the assumption of increased responsibilities. In order to enhance retention and our competitive positioning relative to peers, and taking individual situations into account, base salaries were increased in 2022.

Annual Cash Incentive Awards. Annual cash incentive awards (or bonuses) are determined within a formulaic framework that includes an annual bonus target for each Named Executive Officer, expressed as a percentage of base salary, and the determination of an actual payout as a percentage of such target amount based on company performance relative to specific goals, and individual contributions. Annual company goals typically include financial, safety, environmental and other specified goals, and each goal, as well as the individual performance component, is assigned a weighting or percentage share of the total payout opportunity. Annual goals and objectives, as well as weightings and potential payout ranges (expressed as a percentage of target) are established at the beginning of each year and are discussed and reviewed with the Board in conjunction with the review and approval of our annual plan. Payout percentages relative to achievement of specified goals may range from 0 – 200% of an individual’s target opportunity. The final amounts that are paid may be adjusted by the Compensation Committee and the Board based on factors it deems relevant. Such adjustments may be positive or negative depending on the circumstances.

TABLE OF CONTENTS

2022 Annual Bonus Formula

At the end of each year, the CEO assesses the Company’s performance relative to goals and objectives established at the beginning of the year. The CEO’s written analysis of our performance examines accomplishments and shortfalls relative to established goals and objectives and also assesses overall performance against opportunities and challenges, taking into account controllable and non-controllable factors encountered during the year. The CEO also assesses the individual performance and contributions of each NEO (other than himself) towards the satisfaction of the various goals and objectives established at the beginning of the year. The CEO submits his report and the supporting detail to the Compensation Committee and Board for review and comment. Based on the conclusions set forth in the annual performance assessment, the CEO submits the results of the formulaic bonus calculations along with any recommendations for adjustments to the Compensation Committee for all Named Executive Officers other than himself. In connection with his assessment of Company and individual performance, the CEO also considers various factors, including:

•

whether or not we achieved the goals established for the year and any notable shortfalls relative to expectations;

•

the level of difficulty associated with achieving such objectives based on the opportunities and challenges encountered during the year;

•

current year operating and financial performance relative to both public guidance and prior year’s performance;

•

significant transactions or accomplishments for the period not included in the goals for the year;

•

our relative prospects at the end of the year with respect to future growth and performance; and

•

our equity price performance and returns during the year and our positioning at the end of the year with respect to our targeted leverage metrics and credit profile.

The Compensation Committee may adjust the CEO’s recommendations upward or downward in its discretion. The Compensation Committee’s recommendations are then submitted to the Board for final review and approval.

As noted above, the CEO does not make a recommendation with respect to his own bonus. The Compensation Committee assesses the CEO’s performance and contributions toward meeting the goals and objectives established at the beginning of the year, and then recommends to the Board a total bonus payout for the CEO that it believes to be commensurate with such performance and contributions.

Long-Term Incentive Awards. We use performance and time-based phantom unit grants issued under our Long-Term Incentive Plans to incentivize and retain our executive officers and encourage and reward timely achievement of targeted metrics designed to align the long-term interests of the Named Executive Officers with those of our unitholders.

TABLE OF CONTENTS

2022 Annual LTIP Award; Determination of Units for Annual Grants

NEOs are eligible to receive an annual grant of phantom units based on a formula tied to salary and PAA’s unit price. The size of the annual grant for a specified individual is based on a designated target percentage of their base salary that takes into account their expected contribution in respect of longer term performance objectives.

Annual equity grants typically require minimum service periods of three years in order to encourage long-term retention. A phantom unit grant provides the holder with the right to receive, upon the satisfaction of vesting criteria specified in the grant, a PAA common unit (or cash equivalent). We do not use options as a form of incentive compensation. Terms of phantom unit grants may vary, but generally phantom units vest upon the later of achievement of designated performance thresholds and continued employment for a full three-year period. Phantom unit grants for the Named Executive Officers typically include DERs, and for awards granted in 2022, DERs on the performance-based portion of such awards accrue from the grant date and will be payable only if and to the extent the underlying phantom units vest at the end of the three-year performance period. DERs on the time-based portion of such awards accrue for the first year following the grant date, with such accrued amount being paid out on the first anniversary of the grant date, and then are paid on a quarterly basis thereafter.

Qualitative Goals

•

Financial: strengthen financial positioning and flexibility; complete asset sales of $150 million; achieve a total debt to Adjusted EBITDA ratio of 4.25x or lower by year end; deliver $678 million of free cash flow after distributions (excluding proceeds from asset sales); and return up to 25% of free cash flow after distributions to unitholders.

•

Investment: maintain capital discipline by limiting capital expenditures to no more than $275 million; advance key projects, including emerging energy opportunities, that will support future growth and returns; and optimize existing assets.

•

Operations and Management: advance and complete key programs and initiatives, including convergence efforts, designed to improve the efficiency and scalability of our operations and accounting processes and information systems; progress sustainability goals; and advance key initiatives related to talent development/management, diversity and inclusion, succession planning, employee wellness and performance management.

(1)

Adjusted EBITDA attributable to PAA and Implied DCF are non-GAAP financial measures. Information regarding these non-GAAP financial measures, including a reconciliation to the most directly comparable GAAP measures, is included under the caption “Non-GAAP Financial Measures” beginning on page 72 of PAA’s Annual Report on Form 10-K for the year ended December 31, 2022 as filed with the SEC.

Set forth below are some highlights regarding our 2022 performance relative to our goals and objectives for the year:

•

With respect to Adjusted EBITDA attributable to PAA, we exceeded our goal by 14% driven primarily by volume growth, higher commodity prices and operating performance.

•

In addition to the results set forth in the table above, we also reported Free Cash Flow after Distributions of approximately $828 million (vs. our goal for the year of $678 million).

•

We reduced our debt by $774 million and returned approximately $658 million to common equity holders via distributions and unit repurchases. We exited the year with a leverage ratio of 3.7x, achieving the low end of our target range approximately one year earlier than originally planned. We also ended the year with approximately $3.0 billion of committed liquidity.

•

With respect to our stated goals regarding safety and environmental metrics, we achieved a 35% reduction in federally reportable releases and an 18% reduction in safety-related total recordable injury rate, in each case relative to 2020 results. Notably, over the last six years, we have reduced our federally reportable releases by 74% and our total recordable injuries by 78%.

TABLE OF CONTENTS

In developing his annual bonus compensation recommendations, our CEO primarily considered the quantitative factors and context described above. Other factors noted by our CEO as being relevant to his assessment of our 2022 performance included the following:

•

We substantially completed the integration of the legacy Oryx assets in connection with the October 2021 formation of the Plains Oryx Permian JV (“POP JV”);

•

We added additional dedicated acres to the POP JV and captured additional tariff volumes vs. plan, with a meaningful increase in long-haul volumes;

•

We announced a multi-year capital allocation framework that prioritizes the generation of Free Cash Flow, continued improvement of financial flexibility, and increasing returns of capital to equity holders;

•

We acquired additional interests in the Cactus II and Advantage pipelines;

•

We advanced several debottlenecking projects at our NGL facilities designed to improve efficiencies;

•

We signed agreements to sell our minority interest in the Keyera Ft. Sask JV (this transaction closed in February 2023);

•

We restructured our Empress Joint Venture, which will allow us to improve operating efficiency at our Empress straddle plants;

•

We completed the convergence of our U.S. and Canada Operations Management System; and

•

We advanced several emerging energy projects and continued to make meaningful progress on our efforts to plan for the future and continue to improve effectiveness and efficiency in a variety of areas, including employee development and succession planning, internal systems and processes, safety, integrity, environmental stewardship and sustainability.

2022 Compensation Elements

For 2022, the elements of compensation were applied as described below.

Base Salary. In February 2022, the Compensation Committee recommended, and the Board approved, increases to the base salaries of our Named Executive Officers to maintain competitive pay levels and retain talent. These were the first base salary adjustments since 2017 (other than adjustments in connection with promotions or the assumption of increased responsibility). Following the February 2022 increases, the annual base salaries for the NEOs were as follows:

Named Executive Officer	Annual Base Salary
Willie Chiang		$	800,000
Harry Pefanis		$	600,000
Al Swanson		$	550,000
Richard McGee		$	550,000
Chris Chandler		$	600,000
Jeremy Goebel		$	600,000

Annual Cash Incentive Awards. Annual bonus targets, expressed as a percentage of base salary, were also adjusted in February 2022. Following the February 2022 adjustments, annual bonus targets for the Named Executive Officers, expressed as a percentage of base salary, were as follows:

TABLE OF CONTENTS

Named Executive Officer	Annual Bonus Target (as a Percentage of Base Salary)
Willie Chiang		250%
Harry Pefanis		200%
Al Swanson		150%
Richard McGee		150%
Chris Chandler		150%
Jeremy Goebel		150%

The goals (and weightings) for 2022 cash incentive awards established at the beginning of the year were company performance (67% overall weighting allocated among Adjusted EBITDA attributable to PAA (40%), DCF per common unit and CUE (40%) and safety/environmental (20%)) and individual performance (33% weighting). The minimum and maximum payout levels of 0% and 200%, respectively, for Adjusted EBITDA attributable to PAA and DCF per common unit and CUE were set at 92.5% and 110%, respectively, of the applicable target with linear interpolation between those points, while the minimum and maximum payout levels of 0% and 200%, respectively, for safety and environmental metrics were set at 10% improvement and 30% improvement, respectively, over 2020 results with linear interpolation between those points (2020 results were used as the benchmark for reductions given that 2021 results for each metric were higher than our 2020 results). Individual performance metric payouts were determined by the Compensation Committee based on its assessment of individual contributions towards our 2022 goals and objectives.

The tables below reflect the weighting, payout range and actual results for each company performance metric. Individual performance scores and payout calculations are set forth below under “— Individual Performance.”

Company Performance Payout Thresholds & Ranges: (interpolate between points)

(67% weighting)	Threshold		Target		Max		2022 Formulaic Payout Calculation

Environmental (DOT releases)		10%			15			14			12			11		200%		20%
Company Performance Subtotal																		188.4%

Individual Performance

As noted above, individual performance accounts for 33% of the annual bonus opportunity for our Named Executive Officers. Each officer’s individual contributions toward satisfaction of company goals and objectives is evaluated and payouts may range from 0-200% of target. During 2022, the executive leadership team executed well in an uncertain and volatile environment allowing Plains to successfully capture multiple upsides in the business and deliver results that exceeded plan. The individual payout scores for our NEOs for 2022 are set forth in the table below and take these factors into account, together with the specific items described for each NEO in the table.

Based on a volume weighted average price per unit for the 10-trading day period beginning five days before and ending five days after the ex-dividend date for the August 2022 distribution ($10.91).

(2)

Annual LTIP grants were not awarded to Mr. Pefanis as he requested to not participate in the 2022 long-term incentive program.

The 2022 time-vested phantom units will vest (become payable 1-for-1 in PAA common units) on the August 2025 distribution date. The performance-vested phantom units will potentially vest on the August 2025 distribution date at a scaled payout range of between 0% to 200% based on:

(i)

50% Relative TSR with Negative TSR Modifier: PAA’s TSR measured over the three-year period ending June 30, 2025 compared to the TSR of the TSR Comparator Peer Group identified on page 34 (if PAA’s relative TSR results in a payout of over 100%, but actual TSR is negative, the payout on this portion of the award will be reduced by 25 gross percentage points, but not below 100%); and

(ii)

50% DCF per CUE with Leverage Modifier: PAA achieving cumulative DCF per CUE of $7.05 over the three-year period ending June 30, 2025 (payout may be decreased by 25 basis points if PAA’s leverage ratio as of June 30, 2025 is greater than 3.5x).

DERs associated with the time-vested phantom units will accrue for the first year and such accrued amount will be paid in cash in a lump sum on the August 2023 distribution date; beginning in November 2023, DERs on such time-vested phantom units will be paid quarterly until the associated

TABLE OF CONTENTS

phantom units vest. DERs associated with the performance-vested phantom units will accrue during the three-year performance period and be paid in cash in a lump sum on the August 2025 distribution date with respect to the number of such phantom units, if any, that vest on such date. See the “Grants of Plan Based Awards Table” below for additional information regarding the 2022 annual grants.

Adjustment of Certain Pre-Pandemic Long-Term Incentive Awards

On February 24, 2022, the Board approved, upon the recommendation of the Compensation Committee, amendments to the performance-based portion of long-term incentive awards originally granted in November 2019 to Messrs. Chandler and Goebel (the “2019 Special Grants”). The original terms of the 2019 Special Grants provided as follows:

(i)

50% of the award (250,000 phantom units for each of Messrs. Goebel and Chandler) would vest on the August 2026 distribution date (the “time-based portion”);

(ii)

25% of the award (125,000 phantom units for each of Messrs. Goebel and Chandler) would vest on the later of the August 2026 distribution date and the first distribution date following PAA’s achievement of DCF per CUE of $2.80 on a trailing four quarter basis; and

(iii)

The vesting thresholds for the performance-based portion of the awards (a total of 250,000 phantom units for each of Messrs. Goebel and Chandler) were based on PAA’s pre-pandemic outlook for its business. The pandemic triggered a “reset” of the North American production outlook, which in turn fundamentally changed the key forecasts and outlook upon which such performance metrics were based. As a result, the Compensation Committee and Board decided that the retentive and incentive benefit of the performance-based portion of the 2019 Special Grants had effectively been eliminated. Given the Board’s view that Messrs. Goebel and Chandler are critical to the future leadership of the company, the Board concluded that it would be prudent to reestablish an appropriate amount of retentive and incentive value for these grants, but to do so in a manner that further aligns the interests of these executive officers with the interests of our equity holders. In order to identify a solution that struck this balance, we sought input from our investors during our 2021 engagement effort. We discussed various alternatives with our investors and taking their feedback and input into account, the Compensation Committee and Board ultimately concluded that replacing the original DCF/CUE targets with a relative TSR metric was the most “investor-friendly” way to restore an appropriate amount of retentive and incentive value to the performance-based portion of the 2019 Special Grants. The key features of the amended performance-based portion of the 2019 Special Grants are as follows:

•

Vesting of the performance-based portion of the awards is based on the TSR ranking of PAA relative to a designated comparator group from January 1, 2022 through June 30, 2026, an approximate four and one-half year measurement period with an end date that represents the quarter-end date closest in time to the vesting date for the time-based portion of the original grants;

•

The comparator group is the same comparator group that was used for the TSR metric included in the regular annual equity grants issued by PAA to its NEOs in August 2021, which includes 14 midstream peers, the S&P 500 index, the AMNA index and PAA; and

•

Payout is based on the numeric ranking of PAA’s TSR over the designated performance period relative to the TSR for the various members of the comparator group, with payout capped at 100% (i.e., a performance ranking at the midpoint or in the top half of the comparator group will pay out at 100% and performance in the bottom half will be scaled from 100% payout down to 0% payout). Not allowing a payout above 100% was an important feature based on our engagement discussions with investors as it insured that the maximum payout in terms of the number of performance units remained unchanged from the original grant, thus eliminating the opportunity

for the holders of the 2019 Special Grants to recoup the degradation of value experienced by all unitholders since the 2019 grant date.

Although Mr. Chiang received a pre-pandemic performance-based grant in 2018 that was 100% based on DCF/CUE targets reflecting PAA’s pre-pandemic outlook for its business, the Compensation Committee and the Board elected not to make any changes to such award, which was consistent with Mr. Chiang’s desires. The Compensation Committee and Board also elected not to make any changes to the performance-based portion of the regular annual phantom unit awards that were granted to the NEOs in August 2019; these awards also include DCF/CUE targets based on PAA’s pre-pandemic outlook. See “Outstanding Equity Awards at Fiscal Year End” for a description of the terms of Mr. Chiang’s 2018 promotion grant and the August 2019 annual NEO grants.

Other Compensation Related Matters

Equity Ownership. Our Named Executive Officers and directors collectively own substantial equity interests in PAA and PAGP including unvested long-term equity awards. As of March 27, 2023, the Named Executive Officers beneficially owned, in the aggregate, approximately 12.0 million units of equity interests in PAA and/or PAGP with an approximate market value of $144 million, and all executive officers and directors beneficially owned, in the aggregate, approximately 80.0 million units of equity interests in PAA and/or PAGP with an approximate market value of $963 million.

Equity Ownership Guidelines. In November 2020, the Board adopted Equity Ownership Guidelines to further align the interests of our executive officers and directors with the interests of our unitholders by requiring each to achieve and maintain a minimum equity ownership level. Under these guidelines, each executive officer and director is expected to continuously own PAA and/or PAGP securities with a value equal to a specified multiple of his or her base salary or annual cash retainer as follows:

Title	Multiple of Base Salary or Annual Cash Retainer
CEO		6x
President		5x
EVP		3x
SVP		1x
Director		5x

Executive officers and directors are expected to meet these guidelines within five years after the later of becoming subject to the guidelines or the date of adoption of the guidelines. The compliance date for current executive officers and directors is November 2025, except for Mr. McCarthy whose compliance date is August 2026 and Ms. DeSanctis whose compliance date is August 2027. All current executive officers and directors are on track to meet the applicable guidelines on their respective compliance dates. Executive officers and directors are required to hold 100% of units/shares acquired upon vesting of phantom units or phantom shares until ownership guidelines are met (“hold until met” requirement).

Anti-Hedging and Pledging Policies. We have policies and procedures in place that prohibit our directors and officers, including our Named Executive Officers, from using puts, calls, options or other derivative securities to hedge the economic risk of their equity ownership in us, and from engaging in other types of hedging transactions, including prepaid variable forwards, equity swaps, collars and exchange funds. Our policies also prohibit pledging company securities or holding such securities as marginable securities in a margin account.

Clawback Policy. In November 2020, the Board also adopted a Clawback Policy to further align the interests of our executive officers with the interests of our unitholders, incentivize appropriate behaviors and discourage excessive risk taking. The Clawback Policy covers all executive officers and includes the following clawback triggers and related recoveries:

•

Fraud or intentional/unlawful conduct that contributes to a material financial restatement that results in over-payment of performance-based compensation (Company may seek recovery of any excess compensation awarded or paid); and

TABLE OF CONTENTS

•

Detrimental conduct that results in significant financial, reputational or other harm to the Company (Company may seek recovery or forfeiture of any performance-based compensation or unvested time-based equity awards granted or paid during the 3-year period prior to discovery of the misconduct).

Change in Control Triggers. Our long-term incentive plan grants provide for accelerated vesting upon a change of control (as defined in such agreements), but such vesting becomes operative only if the change in control is accompanied by a “change in status” (which includes the termination of employment by GP LLC without cause and certain other circumstances involving a voluntary separation or retirement). We believe this “double trigger” arrangement is appropriate because it provides assurance to the executive, but does not offer a windfall to the executive when there has been no real change in employment status. In addition, the provisions in Mr. Pefanis’ legacy employment agreement provide for a severance payment if he terminates employment within three months following a change in control. Mr. Pefanis agreed to a conditional waiver of these provisions with respect to all prior qualifying transactions. See “— Potential Payments Upon Termination or Change-in-Control.” The provision of severance or equity acceleration for certain terminations and change of control transactions helps to create a retention tool by assuring the executive that the benefit of the employment arrangement will be at least partially realized despite the occurrence of an event that could materially alter the employment arrangement.

Section 162(m). With respect to the deduction limitations under Section 162(m) of the Internal Revenue Code, we are a limited partnership and do not fall within the definition of a “corporation” under Section 162(m).

Relation of Compensation Policies and Practices to Risk Management

Our compensation policies and practices are designed to provide rewards for short-term and long-term performance, both on an individual basis and at the entity level. In general, optimal financial and operational performance, particularly in a competitive business, requires some degree of risk-taking. Accordingly, the use of compensation as an incentive for performance can foster the potential for management and others to take unnecessary or excessive risks to reach targeted performance thresholds. For us, such risks would primarily attach to certain commercial merchant activities as well as to the execution of investment capital projects and acquisitions and the realization of associated returns.

From a risk management perspective, our policy is to conduct our commercial activities within pre- defined risk parameters that are closely monitored and are structured in a manner intended to control and minimize the potential for unwarranted risk-taking. We also routinely monitor and measure the execution and performance of investment capital projects and acquisitions relative to expectations.

Our compensation arrangements contain a number of design elements that serve to minimize the incentive for unwarranted risk-taking to achieve short-term, unsustainable results, including splitting the awards into a number of tranches and delaying the vesting date for various tranches, in addition to subjecting such awards to forfeiture for terminations related to violations of our risk management policies and practices or of our Code of Business Conduct. In addition, the vesting criteria for long-term incentive awards are typically based on the passage of time and performance thresholds associated with achieving specified long-term financial goals. Also, the fact that we utilize a variety of metrics in connection with our incentive arrangements (both short and long term), including a leverage modifier in the case of our long-term incentive plan grants, provides a structural mitigant against excessive risk taking to achieve performance targets.

In combination with our risk-management practices and the processes employed by the Compensation Committee and the Board, we believe there is an adequate level of oversight with respect to the degree of risk being taken by management to achieve short- and long-term performance goals and we believe that risks arising from our compensation policies and practices for employees are not reasonably likely to have a material adverse effect on us.

Grant date fair values are presented for (i) phantom unit grants awarded to Messrs. Chiang, Swanson, McGee, Chandler and Goebel in August 2020, 2021 and 2022, and (ii) a portion of phantom unit grants awarded to Messrs. Chandler and Goebel in November 2019, which were amended in February 2022. Dollar amounts in the table represent the aggregate fair value of phantom units awarded based on the probable outcome of underlying performance conditions pursuant to FASB ASC Topic 718. See Note 18 to our Consolidated Financial Statements included in our 2022 Annual Report for further discussion regarding the calculation of grant date fair values.

For phantom unit grants awarded to Messrs. Chandler and Goebel in November 2019, 50% were deemed probable of vesting on the grant date. The probability-based fair value of the phantom unit grants awarded in November 2019 was $3,901,500; the maximum fair value of phantom unit grants awarded in November 2019, assuming that the highest level of performance conditions will

be met, was $6,865,000 for each of Messrs. Chandler and Goebel. The November 2019 phantom unit grants were amended in February 2022 to replace the original DCF/CUE metric in the performance-based portion of the award with a relative TSR metric. As a result of the amendment, 100% of the grants were deemed probable of vesting on the amendment date. The amounts presented for each of Messrs. Chandler and Goebel for 2022 include aggregate incremental fair value of $2,486,671 resulting from the amendment of the performance-based portion of the November 2019 awards. The incremental fair value represents the net increase in fair value of the amended awards relative to the fair value on the original grant date.

For phantom unit grants awarded in August 2020, 75% were deemed probable of vesting on the grant date. The maximum fair value of phantom unit grants awarded in August 2020, assuming that the highest level of performance conditions will be met, was $4,494,363 for Mr. Chiang and $1,797,793 for each of Messrs. Swanson, McGee, Chandler and Goebel.

For phantom unit grants awarded in August 2021, 75% were deemed probable of vesting on the grant date. The maximum fair value of phantom unit grants awarded in August 2021, assuming that the highest level of performance conditions will be met, was $2,738,466 for Mr. Chiang and $1,095,022 for each of Messrs. Swanson, McGee, Chandler and Goebel.

For phantom unit grants awarded in August 2022, 75% were deemed probable of vesting on the grant date. The maximum fair value of phantom unit grants awarded in August 2022, assuming that the highest level of performance conditions will be met, was $7,854,000 for Mr. Chiang, $2,474,010 for each of Messrs. Swanson and McGee, and $3,189,795 for each of Messrs. Chandler and Goebel.

As referenced previously, Mr. Pefanis is a co-founder and substantial equity owner and for the last several years, despite being eligible for equity awards, has requested to not participate in the long-term incentive program.

Represents the performance-vested portion of phantom units granted in August 2022. These phantom units will potentially vest on the August 2025 distribution date at a scaled payout range of between 0% and 200% based on: (i) with respect to 50% of the performance-vested award, PAA’s TSR over the three-year period ending June 30, 2025 compared to the TSR of the TSR Comparator Peer Group described on page 34 (payout may be reduced if absolute TSR is negative); and (ii) with respect to the other 50% of the performance-vested award, PAA achieving cumulative DCF per CUE of $7.05 over the three-year period ending June 30, 2025 (payout may be decreased by 25 basis points if PAA’s leverage ratio as of June 30, 2025 is greater than 3.5x). DERs associated with the performance-vested portion will accrue during the three-year performance period and be paid in cash in a lump sum on the August 2025 distribution date with respect to the number of such phantom units, if any, that vest on such date.

(2)

Represents the time-vested portion of phantom units granted in August 2022. These phantom units will vest on the August 2025 distribution date. DERs associated with the time-vested portion will accrue for the first year and such accrued amount will be paid in cash in a lump sum on the August 2023 distribution date; beginning in November 2023, DERs on such time-vested portion will be paid quarterly until the associated phantom units vest.

TABLE OF CONTENTS

(1)

Market value of phantom units reported in these columns is calculated by multiplying the closing market price ($11.76) of PAA’s common units at December 30, 2022 (the last trading day of the fiscal year) by the number of units. No discount is applied for remaining performance threshold or service period requirements.

(2)

Represents phantom units granted to Mr. Chiang in August 2018. These phantom units, which were granted in connection with Mr. Chiang’s promotion to CEO, will vest as follows: (i) 25% will vest upon the later of October 1, 2023 and the first distribution date on which PAA will have generated DCF per common unit of at least $3.00 on a trailing four quarter basis, and (ii) 75% will vest upon the later of October 1, 2023 and the first distribution date on which PAA will have generated DCF per common unit of at least $3.50 on a trailing four quarter basis, in both cases with the initial performance-related measurement period beginning on or after January 1, 2021. Upon vesting, the phantom units are payable on a one-for-one basis in PAA common units. Any phantom units or DERs that have not vested by October 1, 2025 will expire at that time. The phantom units have associated DERs that have vested or will vest as follows: (i) one-third vested on the May 2019 distribution date as a result of PAA generating DCF per common unit of at least $2.50 on a trailing four quarter basis, (ii) one-third will vest on the first distribution date on which PAA generates DCF per common unit of at least $2.60 on a trailing four quarter basis, and (iii) one-third will vest on the first distribution date on which PAA generates DCF per common unit of at least $2.80 on a trailing four quarter basis; provided that in the case of the performance thresholds described in clauses (ii) and (iii) immediately preceding, the applicable trailing four quarter period must begin on or after January 1, 2020.

(3)

Represents 50% of phantom units granted in August 2019 that will vest on the first distribution date following PAA’s achievement of DCF per common unit of at least $2.65 on a trailing four quarter basis. The applicable trailing four quarter period for determining whether the requisite DCF per common unit has been achieved for vesting of such phantom units may not begin until after December 31, 2020. The associated DERs will vest on the first distribution date following January 1, 2021 on which PAA achieves DCF per common unit of at least $2.50 on a trailing four quarter basis. Any phantom units and associated DERs that have not vested by the August 2024 distribution date will expire at that time.

Represents the applicable portion of one-time special retention phantom unit awards granted in November 2019. The original terms of these phantom units provided that they would vest (i) 50% on the August 2026 distribution date, (ii) 25% on the later of the August 2026 distribution date and the first distribution date following PAA’s achievement of DCF per common unit and CUE of at least $2.80 on a trailing four quarter basis, and (iii) 25% on the later of the August 2026 distribution date and the first distribution date following PAA’s achievement of DCF per common unit and CUE of at least $3.15 on a trailing four quarter basis. Vesting of a portion of the associated DERs was also tied to PAA’s achievement of specified DCF per common unit and CUE levels. The vesting terms with respect to the performance-based portion of these phantom units (50% of the amount awarded) were amended in February 2022. As amended, the November 2019 phantom unit awards will vest as follows: (i) 50% will vest on the August 2026 distribution date (this is unchanged from the original terms), and (ii) up to 50% will potentially vest at a scaled payout range of between 0% and 100% based on the TSR ranking of PAA relative to a designated comparator group as measured over a four and one-half year period beginning on January 1, 2022 and ending on June 30, 2026. The unvested DERs associated with the November 2019 phantom unit awards that were originally tied to achievement of DCF/CUE targets were also amended such that they began accruing on January 1, 2022 and will be paid in cash in a lump sum on the August 2026 distribution date with respect to the number of phantom units, if any, that vest on such date.

DERs will accrue during the three-year vesting period and be paid in cash in a lump sum on the August 2023 distribution date with respect to the number of phantom units, if any, that vest on such date. Any phantom units and associated DERs that have not vested by the August 2023 distribution date will expire at that time.

(8)

DERs will accrue during the three-year performance period and be paid in cash in a lump sum on the August 2024 distribution date with respect to the number of phantom units, if any, that vest on such date. Any phantom units and associated DERs that have not vested by the August 2024 distribution date will expire at that time.

The letter evidencing the August 2018 phantom unit grant to Mr. Chiang provides that in the event of his death or disability after the second anniversary of the date of the applicable grant, all of his then outstanding phantom units awarded under such grants will be deemed nonforfeitable and will vest on the next following distribution date (and any associated DERs shall not be forfeited but shall vest, be payable and expire according to the terms of the applicable phantom unit grant letter).

The letters evidencing the August 2019, August 2020, August 2021 and August 2022 phantom unit grants awarded to Messrs. Chiang, Swanson, McGee, Chandler and Goebel provide that in the event of their death or disability after the first anniversary of the date of the applicable grant, all of their then outstanding phantom units awarded under such grants will be deemed nonforfeitable and will vest on the next following distribution date (and any associated DERs shall not be forfeited but shall vest, be payable and expire according to the terms of the applicable phantom unit grant letter).

The letter evidencing the December 2017 phantom unit grant awarded to Mr. Goebel provides that in the event of his death or disability, all of his then outstanding phantom units awarded under such grant will be deemed nonforfeitable and will vest on the next following distribution date (and any associated DERs shall not be forfeited but shall vest, be payable and expire according to the terms of the phantom unit grant letter).

The letters evidencing the November 2019 phantom unit grants awarded to Messrs. Chandler and Goebel, as amended, provide that in the event of their death or disability after the second anniversary of the date of grant, all of their then outstanding phantom units awarded under such

TABLE OF CONTENTS

grants and associated DERs will be deemed nonforfeitable, and will vest on the next distribution date (assuming a TSR payout percentage of 100% with respect to the performance-based portion of the award).

For these purposes, “disability” means a physical or mental infirmity that impairs the ability substantially to perform duties for a period of eighteen (18) months or that the general partner otherwise determines constitutes a disability.

Assuming death or disability occurred on December 31, 2022, (A) all of the phantom units and associated DERs held by Messrs. Chiang, Swanson, McGee, Chandler and Goebel pursuant to their August 2019, August 2020 and August 2021 grant letters, all of the phantom units and associated DERs held by Mr. Chiang pursuant to his August 2018 grant letter, all of the phantom units and associated DERs held by Mr. Goebel pursuant to his 2017 grant letter, and all of the phantom units and associated DERs held by Messrs. Chandler and Goebel pursuant to their November 2019 grant letters would have become nonforfeitable as of such date and would have vested on the February 2023 distribution date, and (B) all of the phantom units and associated DERs held by Messrs. Chiang, Swanson, McGee, Chandler and Goebel pursuant to their August 2022 grant letters would have been forfeited. The dollar value given is based on the market value of PAA’s common units on December 30, 2022 ($11.76 per unit).

(2)

Other than as described below, pursuant to the grant letters for the currently outstanding phantom unit grants awarded to the NEOs, if GP LLC terminated their employment other than for cause (as defined in footnote 3 below), all of their unvested phantom units awarded under such grants and associated DERs shall be deemed nonforfeitable on the date of such termination and shall vest on the next following distribution date.

The phantom units granted to Messrs. Chandler and Goebel in November 2019, as amended, provide that if their employment is terminated other than for cause (as defined in footnote 3 below), a portion of the unvested phantom units will be deemed nonforfeitable and will vest on the next following distribution date, with the size of the portion starting at 40% for a termination prior to November 21, 2022, and increasing by 20% per year thereafter such that 100% of the unvested phantom units would be deemed nonforfeitable following a termination other than for cause on or after November 21, 2024.

The phantom units granted to Messrs. Chiang, Swanson, McGee, Chandler and Goebel in August 2020, August 2021 and August 2022 provide that if their employment is terminated other than for cause prior to the first anniversary of the applicable date of grant, all of their unvested phantom units will be forfeited as of the date of such termination. If such termination occurs after the first anniversary of the applicable date of grant, a pro rata portion of the unvested phantom units (based on the portion of the three-year vesting period that has elapsed since the grant date and assuming a payout at target for any performance-based phantom units) will be deemed nonforfeitable and will vest on the next following distribution date.

Mr. Chiang’s August 2018 phantom unit grant provides that if his employment is terminated other than for cause (as defined in footnote 3 below) a portion of the unvested phantom units will be deemed nonforfeitable and will vest on the next following distribution date, with the size of the portion starting at 20% for a termination prior to October 1, 2019, and increasing to 40% for a termination other than for cause between October 1, 2019 and October 1, 2020, 60% for a termination other than for cause between October 1, 2020 and October 1, 2021 and 100% for a termination other than for cause on or after October 1, 2021.

Assuming our Named Executive Officers were terminated without cause on December 31, 2022, (i) all of the phantom units covered by the August 2019 phantom unit grants held by Messrs. Chiang, Swanson, McGee, Chandler and Goebel, approximately 79% of the phantom units covered by the August 2020 phantom unit grants held by Messrs. Chiang, Swanson, McGee, Chandler and Goebel, all of the phantom units covered by the December 2017 phantom unit grant held by Mr. Goebel, 46% of the phantom units covered by the August 2021 phantom unit grants held by Messrs. Chiang, Swanson, McGee, Chandler and Goebel, 60% of the phantom units covered by the November 2019 phantom unit grants held by Messrs. Chandler and Goebel and 100% of the phantom units covered by the August 2018 phantom unit grant held by Mr. Chiang would have vested on the February 2023 distribution date, and (ii) all remaining phantom units held by our Named

TABLE OF CONTENTS

Executive Officers would have become automatically forfeited as of such date of termination. The dollar value given is based on the market value of PAA’s common units on December 30, 2022 ($11.76 per unit).

(3)

The letters evidencing phantom unit grants awarded to the Named Executive Officers provide that in the event of a change in status (as defined below), all of the then outstanding phantom units awarded under such grants and associated DERs will be deemed nonforfeitable, and such phantom units will vest in full (i.e., the phantom units will become payable in the form of one common unit per phantom unit) upon the next following distribution date. Assuming that a change in status occurred on December 31, 2022, all outstanding phantom units awarded under such grants and the associated DERs would have become nonforfeitable as of December 31, 2022, and such phantom units would vest on the February 2023 distribution date. The dollar value given is based on the market value of PAA’s common units on December 30, 2022 ($11.76 per unit).

The phrase “change in status” means, with respect to a Named Executive Officer, (A) during the period (“protected period”) beginning two and a half months prior to and ending one year following a change of control (as defined below), the termination of employment by GP LLC other than a termination for cause (as defined below), (B) during the protected period, the termination of employment by the Named Executive Officer due to the occurrence, without the Named Executive Officer’s written consent, of (i) any material diminution in the Named Executive Officer’s authority, duties or responsibilities, (ii) any material reduction in the Named Executive Officer’s base salary or (iii) any other action or inaction that would constitute a material breach of the applicable grant letter by GP LLC, or (C) the termination of employment as a result of retirement on terms and timing that are approved by the CEO (or the Board in the case of the CEO).

The phrase “change of control” is defined in phantom unit grants awarded in 2017 to mean, and is deemed to have occurred upon the occurrence of, one or more of the following events: (i) the Persons who owned member interests in PAGP GP immediately following the closing of PAGP’s initial public offering, including PAGP, and the respective Affiliates of such Persons (such owners and Affiliates being referred to as the “Owner Affiliates”), cease to own directly or indirectly at least 50% of the membership interests of such entity; (ii) (x) a “person” or “group” other than the Owner Affiliates becomes the “beneficial owner” directly or indirectly of 25% or more of the member interest in the general partner of PAGP, and (y) the member interest beneficially owned by such “person” or “group” exceeds the aggregate member interest in the general partner of PAGP beneficially owned, directly or indirectly, by the Owner Affiliates; or (iii) a direct or indirect transfer, sale, exchange or other disposition in a single transaction or series of transaction (whether by merger or otherwise) of all or substantially all of the assets of PAGP or PAA to one or more Persons who are not Affiliates of PAGP (“third party or parties”), other than a transaction in which the Owner Affiliates continues to beneficially own, directly or indirectly, more than 50% of the issued and outstanding voting securities of such third party or parties immediately following such transaction.

The phrase “change of control” is defined in the outstanding phantom unit grants awarded in 2018, 2019, 2020, 2021, 2022 to mean, and is deemed to have occurred upon the occurrence of, one or more of the following events: (i) any Person (other than 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 PAGP GP; (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; (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 PAA; or (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 PAA 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 “Exchange Act”).

TABLE OF CONTENTS

“Cause” is defined in the 2017, 2018, 2019, 2020, 2021 and 2022 phantom unit grant agreements as (i) failure to perform the duties and responsibilities of a position at an acceptable level as reasonably determined in good faith by the CEO of GP LLC (or by the Board in the case of the CEO), (ii) the 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 GP LLC’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 in writing.

(4)

Mr. Pefanis’ employment agreement provides that if (i) his employment is terminated as a result of his death, (ii) he terminates his employment (a) because of a disability (as defined in Section 409A of the Code) or (b) for good reason (as defined below), or (iii) GP LLC terminates his employment without cause (as defined below), he is entitled to a lump-sum amount equal to the product of (1) the sum of his (a) highest annual base salary paid prior to his date of termination and (b) highest annual bonus paid or payable for any of the three years prior to the date of termination, and (2) the lesser of (i) two or (ii) the number of days remaining in the term of his employment agreement divided by 360. The amount provided in the table assumes a termination date of December 31, 2022 with two years remaining on the term of his agreement, and also assumes a highest annual base salary of $600,000 and highest annual bonus of $2,105,000.

Mr. Pefanis’ employment agreement defines “cause” as (i) willfully engaging in gross misconduct, or (ii) conviction of a felony involving moral turpitude. Notwithstanding, no act, or failure to act, on his part is “willful” unless done, or omitted to be done, not in good faith and without reasonable belief that such act or omission was in the best interest of GP LLC or otherwise likely to result in no material injury to GP LLC. However, Mr. Pefanis will not be deemed to have been terminated for cause unless and until there is delivered to him a copy of a resolution of the Board at a meeting held for that purpose (after reasonable notice and an opportunity to be heard), finding that Mr. Pefanis was guilty of the conduct described above, and specifying the basis for that finding. If Mr. Pefanis were terminated for cause, GP LLC would be obligated to pay base salary through the date of termination, with no other payment obligations triggered by the termination under the employment agreement or other employment arrangement.

Mr. Pefanis’ employment agreement defines “good reason” as the occurrence of any of the following circumstances: (i) removal by GP LLC from, or failure to re-elect him to, the position to which Mr. Pefanis was appointed pursuant to his employment agreement, except in connection with his termination for cause (as defined above); (ii) (a) a reduction in his rate of base salary (other than in connection with across-the-board salary reductions for all executive officers of GP LLC) to an amount which is less than 85% of his current base salary, (b) a material reduction in his fringe benefits, or (c) any other material failure by GP LLC to comply with its obligations under the employment agreement to pay his annual salary and bonus, reimburse his business expenses, provide for his participation in certain employee benefit plans and arrangements, furnish him with suitable office space and support staff, or allow him no less than 15 business days of paid vacation annually; or (ii) the failure of GP LLC to obtain the express assumption of the employment agreement by a successor entity (whether direct or indirect, by purchase, merger, consolidation or otherwise) to all or substantially all of the business and/or assets of GP LLC.

(5)

Pursuant to his employment agreement, if Mr. Pefanis terminates his employment with GP LLC within three months of a Change in Control (as defined below), he is entitled to a lump-sum payment in an amount equal to the product of (i) three and (ii) the sum of (a) his highest annual base salary previously paid to him and (b) his highest annual bonus paid or payable for any of the three years prior to the date of such termination. The amount provided in the table assumes a Change in Control and termination date of December 31, 2022, and also assumes a highest annual base salary of $600,000 and highest annual bonus of $2,105,000.

In conjunction with events occurring in 2005, 2010 and 2013, Mr. Pefanis executed various agreements waiving his right to terminate his employment and receive separation benefits under his employment agreement. In connection with such waivers, the definition of “Change in Control” in Mr. Pefanis’ employment agreement was modified to mean, and will be deemed to occur upon, one or more of the following events: (i) any person (other than PAGP or its wholly owned subsidiaries),

TABLE OF CONTENTS

including any partnership, limited partnership, syndicate or other group deemed a “person” for purposes of Section 13(d) or 14(d) of the Exchange Act becomes the beneficial owner, directly or indirectly, of 50% or more of the membership interest in GP LLC or 50% or more of the outstanding limited partnership interest of PAGP; (ii) any person (other than PAGP or its wholly owned subsidiaries), including any partnership, limited partnership, syndicate or other group deemed a “person” for purposes of Section 13(d) or 14(d) of the Exchange Act, becomes the beneficial owner, directly or indirectly, of 50% or more of the membership interest in PAGP GP; (iii) PAGP ceases to beneficially own, directly or indirectly, more than 50% of the membership interest in GP LLC; (iv) the “Owner Affiliates”, as defined in the 2013 waiver agreement, cease to beneficially own, directly or indirectly, more than 50% of the membership interest in PAGP GP; or (v) there has been a direct or indirect transfer, sale, exchange or other disposition in a single transaction or series of transactions (whether by merger or otherwise) of all or substantially all of the assets of PAGP or PAA to one or more persons who are not affiliates of PAGP (“third party” or “parties”), other than a transaction in which the Owner Affiliates continue to beneficially own, directly or indirectly, more than 50% of the issued and outstanding voting securities of such third party or parties immediately following such transaction.

(6)

Pursuant to his employment agreement, if Mr. Pefanis is terminated other than (i) for cause (as defined in footnote 4 above), (ii) by reason of death or (iii) by resignation (unless such resignation is due to a disability or for good reason (each as defined in footnote 4 above)), then he is entitled to continue to participate, for a period which is the lesser of two years from the date of termination or the remaining term of the employment agreement, in such health and accident plans or arrangements as are made available by GP LLC to its executive officers generally. The amounts provided in the table assume a termination date of December 31, 2022 with two years remaining on the term of his agreement.

(7)

If Messrs. Chiang, Pefanis, Swanson, McGee, Chandler or Goebel were terminated for cause, GP LLC would be obligated to pay base salary through the date of termination, with no other payment obligation triggered by the termination under any employment arrangement.

Mr. Pefanis has agreed to maintain the confidentiality of PAA information for a period of one year following the termination of his employment. Messrs. McGee and Chandler have each agreed to maintain the confidentiality of certain information and not to solicit customers for a period of two years after termination of their employment.

A list was prepared of all individuals, excluding the CEO, who were employed by PAA on December 31, 2022. We included all U.S. and Canadian employees.

•

Basic wage data for each U.S. employee was extracted from Form W-2 information provided to the Internal Revenue Service for calendar year 2022. Basic wage data for each Canadian employee was extracted from Form T4 information provided to the Canada Revenue Agency for

calendar year 2022 and converted to U.S. dollars. This information was then sorted and the median employee was identified.

The median employee’s annual total compensation for 2022 was determined using the same methodology we used for determining the annual total compensation for the Named Executive Officers as set forth in the 2022 Summary Compensation Table.

Pay Versus Performance

As required by Item 402(v) of Regulation S-K, we are providing the following information about the relationship between executive compensation actually paid (“CAP”) and PAA’s financial performance for the periods presented. The CAP dollar amounts shown in the table below have been calculated in accordance with SEC rules; however, meaningful amounts included as CAP (e.g., approximately two-thirds of CAP for our PEO in 2022) do not represent compensation actually paid or earned during the applicable years. This is due to the fact that CAP includes, in addition to base salary, bonus, the value of equity awards that vested during the year and DERs (“realized value”), the value of outstanding equity awards that could potentially vest in future years (“potentially realizable future value”). With respect to our principal executive officer (“PEO”) for 2022, ~34.5% of the ~$14.5 million of CAP (or ~$5 million) represents the “realized value” of amounts actually paid to or earned by our PEO and ~65.5% (or ~$9.5 million) represents “future potentially realizable value” of outstanding equity awards. With respect to our other NEOs (“Non-PEO NEOs”) for 2022, ~43% of the ~$8.1 million of average CAP (or ~$3.5 million) represents the “realized value” of amounts actually paid to or earned by our non-PEO NEOs and ~57% (or ~$4.6 million) represents “future potentially realizable value” of outstanding equity awards.

Tabular Disclosure of Compensation Actually Paid versus Performance

The following table discloses information on CAP to our PEO and, on average, to our Non-PEO NEOs during the specified years alongside TSR, net income, and the Company-selected measure of Adjusted EBITDA Attributable to PAA. Adjusted EBITDA Attributable to PAA was identified by the Company as the most important financial performance measure used to link CAP to Company performance.

The dollar amounts shown in these columns reflect CAP as calculated in accordance with SEC rules. As required, the dollar amounts include (among other items) values for unvested equity compensation that may or may not be realized in future periods, and as such, the dollar amounts shown do not necessarily represent the actual amount of compensation earned or paid during the applicable years.

TSR figures assume an initial investment of $100 in PAA on December 31, 2019. The peer group referenced for purposes of the TSR comparison is the group of companies included in the Alerian Midstream Energy Index, which is the same index used for purposes of Item 201(e) of Regulation S-K.

Mr. Armstrong served as Senior Advisor to the CEO during 2022 and received a salary of $250,000 and other compensation of $15,840 (comprising 401(k) plan matching contributions and premium payments for group term life insurance) for his services as an employee. Pursuant to his employment agreement, Mr. Armstrong will serve as a director and will also serve as Senior Advisor to the CEO until the date of the 2024 annual meeting and will receive an annual salary of $250,000 for these services. Mr. Armstrong does not hold any LTIP awards.

(3)

Ms. DeSanctis joined the Board in August 2022; amounts shown in the table above reflect compensation for a partial year of service.

Cash Retainers and Expense Reimbursement

Our non-employee directors receive an annual retainer fee of $115,000. In addition to their annual retainer, each committee chairman (other than the Audit Committee chairman) receives an additional retainer of $15,000, the Audit Committee chairman receives an additional retainer of $30,000, each other member of the Audit Committee receives an additional retainer of $15,000, and the Lead Director receives an additional retainer of $35,000. The foregoing amounts reflect increases in annual retainer and non-audit committee chair fees that were implemented in the second quarter of 2022 to maintain competitive positioning among peers. Fee payment amounts shown in the table above reflect blended rates.

Non-employee directors are reimbursed for reasonable travel, lodging and other out-of-pocket expenses related to meeting attendance or otherwise related to service on the Board (including, without limitation, reimbursement for continuing education expenses).

Messrs. Armstrong, Chiang and Pefanis are otherwise compensated for their services as employees and therefore receive no separate compensation for their services as directors.

Long-Term Equity Awards

Our non-employee directors receive annual LTIP awards as part of their compensation. Such LTIP awards consist of PAGP phantom Class A shares having a market value on the date of grant equal to approximately $125,000 (based on a volume weighted average price for the 10-trading day period beginning five days before and ending five days after the ex-dividend date immediately preceding the date of grant). The annual LTIP awards granted in 2022 will vest (become payable in PAGP Class A shares on a one-for-one basis) on the August 2023 distribution date, and include associated DERs. Outstanding director LTIP awards granted prior to 2022 will vest four years after the date of grant.

All director LTIP awards vest in full upon the next following distribution date after the death or disability (as determined in good faith by the Board) of the director. The awards also vest in full if a director (i) retires (no longer with full-time employment and no longer serving as an officer or director of any public

company) or (ii) is removed from the Board or is not reelected to the Board, unless such removal is for “Cause,” as defined in the PAGP GP LLC Agreement.

Reimbursement of Expenses of Our General Partner and its Affiliates

We do not pay our general partner a management fee, but we do reimburse our general partner for all direct and indirect costs of services provided to us, incurred on our behalf, including the costs of employee, officer and director compensation and benefits allocable to us, as well as all other expenses necessary or appropriate to the conduct of our business, allocable to us. We record these costs on the accrual basis in the period in which our general partner incurs them. Our partnership agreement provides that our general partner will determine the expenses that are allocable to us in any reasonable manner determined by our general partner in its sole discretion.

The 2021 Long-Term Incentive Plan (the “2021 Plan”), which was approved by our unitholders in May 2021, amended, restated and renamed the 2013 Long-Term Incentive Plan (the “2013 Plan” or “prior plan”). The 2021 Plan contemplates the issuance or delivery of up to 28,786,102 common units to satisfy awards under the plan, which amount is net of 9,063,516 common units previously issued under the prior plan. The number of units presented in column (a) assumes that all outstanding grants will be satisfied by the issuance of new units upon vesting unless such grants are by their terms payable only in cash. Some portion of the phantom units may be settled in cash or will be withheld for taxes. Any units not issued upon vesting will become “available for future issuance” under column (c).

(2)

Phantom unit awards under the 2021 Plan and PNG Successor Plan (defined below) vest without payment by recipients.

(3)

In accordance with Item 201(d) of Regulation S-K, column (c) excludes the securities disclosed in column (a). However, as discussed in footnotes (1) and (4), any phantom units represented in column (a) that are not satisfied by the issuance of units become “available for future issuance.”

(4)

In December 2013, in connection with the PNG Merger, we adopted and assumed the PAA Natural Gas Storage, L.P. 2010 Long Term Incentive Plan (the “PNG Legacy Plan”), and all outstanding awards of PNG phantom units were converted into comparable awards of PAA phantom units by applying the merger exchange ratio of 0.445 PAA common units for each PNG common unit and rounding down for any fractions. The GP LLC board of directors amended and restated the PNG Legacy Plan, which is now known as the PNG Successor Long-Term Incentive Plan (the “PNG Successor Plan”). The PNG Successor Plan contemplates the issuance or delivery of up to 1,319,983 units to satisfy awards under the plan, which amount is net of 15,017 common units previously issued under the PNG Legacy Plan. The number of units presented in column (a) assumes that all outstanding grants will be satisfied by the issuance of new units upon vesting unless such LTIPs are by their terms payable only in cash. Some portion of the phantom units may be settled in cash or will be withheld for taxes. Any units not issued upon vesting will become “available for future issuance” under column (c).

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Our General Partner

Our operations and activities are managed, and our officers and personnel are employed, by our general partner (or, in the case of our Canadian operations, Plains Midstream Canada ULC). We do not pay our general partner a management fee, but we do reimburse our general partner for all expenses incurred on our behalf (other than expenses related to the AAP Management Units). Total costs reimbursed by us to our general partner for the year ended December 31, 2022 were approximately $476 million.

Our general partner owns a non-economic general partner interest in us and, as of March 27, 2023, owned approximately 241.0 million common units (representing approximately 31% of our outstanding common units and Series A preferred units combined). This limited partner interest entitles our general partner to receive quarterly distributions at the same rate as other common unitholders; however, these units are not entitled to vote in the election of directors.

Equity-Based Long-Term Incentive Plans

General

In May 2021, our unitholders approved the adoption of the 2021 Plan, which amended, restated and renamed the 2013 Plan. In December 2013, in connection with the PNG Merger, we adopted and assumed the PNG Legacy Plan, and all outstanding awards of PNG phantom units were converted into comparable awards of PAA phantom units by applying the merger exchange ratio of 0.445 PAA common units for each PNG common unit and rounding down for any fractions. The Board amended and restated the PNG Legacy Plan, which is now known as the PNG Successor Plan (together with the 2021 Plan, the “Plans”). The provisions of the PNG Successor Plan are substantially the same as the 2013 Plan, except that new awards under the PNG Successor Plan may only be made to employees hired after the date of the PNG Merger. Awards contemplated by the Plans include phantom units, unit appreciation rights, restricted units, options, DERs and cash awards. The 2021 Plan authorizes the grant of awards covering an aggregate of 28,786,102 common units deliverable upon vesting or exercise (as applicable) of such awards. The PNG Successor Plan authorizes the grant of awards covering an aggregate of 1,319,983 common units deliverable upon vesting or exercise (as applicable) of such awards.

The Plans are administered by the Compensation Committee or other Board committee appointed to administer the Plans, or by the Board. The plan administrator has the right to terminate or amend the Plans from time to time, including, subject to any applicable Nasdaq listing requirements, increasing the number of common units available for awards under the Plans. No change may be made to any outstanding grant that would materially reduce the benefits of the holder of such grant without the consent of such holder.

Common units to be delivered upon the vesting and settlement of awards may be common units acquired in the open market, newly issued common units, common units acquired from us, any of our affiliates or any other person, or any combination of the foregoing. Our general partner will be entitled to reimbursement by us for the cost incurred in acquiring common units. When we issue new common units upon vesting and settlement of grants, the total number of common units outstanding increases.

Pursuant to the terms of the 2021 Plan, if any Award is forfeited, canceled, exercised or otherwise terminated without the actual delivery of common units pursuant to such Award, or if any common units under an Award are held back to cover tax withholding, then, in either such case, any common units that are so forfeited, canceled, exercised or otherwise terminated without the actual delivery of common units or held back to cover tax withholding (excluding Restricted Unit Awards) shall be available to satisfy future Awards under the 2021 Plan. Units tendered or withheld in payment of any exercise or purchase price of an Award, units that were subject to an option or unit appreciation right but were

TABLE OF CONTENTS

not issued or delivered as a result of the net settlement of such Award, and units repurchased on the open market with the proceeds of an option’s exercise price, will not, in each case, be available for future Awards under the 2021 Plan.

As of December 31, 2022, grants of approximately 10,726,985 and 400,335 unvested phantom units were outstanding under the 2021 Plan and PNG Successor Plan, respectively, and approximately 17,321,618 and 3,049 remained available for future grant, respectively. The plan administrator may, in the future, make additional grants under the Plans to employees and directors containing such terms as the plan administrator shall determine.

Awards

Phantom Units. A phantom unit entitles the grantee to receive, upon the vesting of the phantom unit, a common unit (or cash equivalent, depending on the terms of the grant). The issuance of the common units upon vesting of phantom units is primarily intended to serve as a means of incentive compensation for performance. Therefore, no consideration is paid to us by the plan participants upon receipt of the common units.

Unit Appreciation Rights. A unit appreciation right is an award that, upon exercise, entitles the holder to receive the excess, if any, of the fair market value of a common unit on the exercise date over the grant price of the unit appreciation right. The excess may be paid in cash and/or common units as determined by the plan administrator in its discretion, provided that unit appreciation rights may not have an exercise price that is less than the fair market value of the common units on the date of grant. No unit appreciation rights have been granted under the Plans to date.

Restricted Unit Awards. A restricted unit is a common unit that is subject to a risk of forfeiture, restrictions on transferability, and any other restrictions that may be imposed by the plan administrator in its discretion. No restricted unit awards have been granted under the Plans to date.

Options. Options may be granted to purchase a specific number of common units at a set exercise price. The exercise price of each option granted under the Plan will be determined by the plan administrator at the time the option is granted, provided no each option may have an exercise price that is less than the fair market value of the common units on the date of grant. No options have been granted under the Plans to date.

Distribution Equivalent Rights. Awards granted under the Plans (other than Restricted Unit Awards) may include DERs. DERs entitle the grantee to a cash payment, either while the Award is outstanding or upon vesting, equal to the cash distributions paid on a unit while the Award is outstanding.

Cash Awards. Cash Awards may be granted on a free-standing basis or as an element of, as a supplement to, or in lieu of any other Award granted under the 2021 Plan.

Other Provisions

Tax Withholding. Our General Partner or one of its affiliates are authorized to withhold from any Award, from any payment due or transfer made under any Award or from any compensation or other amount owing to a plan participant, the amount (in cash, common units, other securities or other property) of any applicable taxes payable with respect to the grant of an Award, its exercise, the lapse of restrictions applicable to an Award or in connection with any payment relating to an Award or the transfer of an Award and to take such other actions as may be necessary to satisfy any tax withholding obligations with respect to an Award.

Change of Control. Except to the extent specifically provided in an Award agreement, vesting of an Award shall not occur solely upon a change of control.

Minimum Vesting Requirement. The 2021 Plan provides that Awards that must or may be settled in units shall vest no earlier than the first anniversary of the date the Award is granted. Notwithstanding the foregoing, Awards that result in the issuance of an aggregate of up to 5% of the units available

TABLE OF CONTENTS

for issuance under the 2021 Plan may be granted to one or more plan participants without regard to this minimum vesting requirement.

Equity Ownership Guidelines. The plan administrator retains the discretion under the 2021 Plan to impose a holding period with respect to an Award or the units received in connection with an Award. Pursuant to the Equity Ownership Guidelines adopted by our Board in November 2020, our executive officers and Directors will be required to hold 100% of any units acquired upon vesting of Awards until the applicable ownership requirements are met.

Clawback Policy. The 2021 Plan provides that all Awards granted thereunder are subject to any written clawback policies that we may adopt, including any policy adopted to conform to the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules promulgated thereunder. Pursuant to the Clawback Policy adopted by our Board in November 2020, the Company may seek from our executive officers (i) recovery of any excess performance-based compensation awarded or paid in the event of fraud or intentional or unlawful conduct that contributes to a material financial restatement that results in over-payment of performance-based compensation, and (ii) recovery or forfeiture of any performance-based compensation or unvested time-based equity awards granted or paid during the three-year period prior to discovery of detrimental conduct that results in significant financial, reputational or other harm to the Company.

Transferability of Awards. Options and unit appreciation rights are only exercisable by the plan participant during the plan participant’s lifetime, or by the person to whom the plan participant’s rights pass by will or the laws of descent and distribution. No Award or right granted under the 2021 Plan may be assigned, alienated, pledged, attached, sold or otherwise transferred or encumbered and any such purported transfer shall be void and unenforceable. Notwithstanding the foregoing, the plan administrator may, in its discretion, allow a plan participant to transfer an option or a unit appreciation right without consideration to an immediate family member or a related family trust, limited partnership, or similar entity on the terms and conditions established by the plan administrator from time to time, provided that no Award may be transferred to a third-party financial institution for value.

Anti-Dilution Adjustments. Upon the occurrence of any “equity restructuring” event that could result in an additional compensation expense under FASB ASC Topic 718 if adjustments to Awards with respect to such event were discretionary, the plan administrator will equitably adjust the number and type of common units covered by each outstanding Award and the terms and conditions of such Award to equitably reflect the restructuring event, and the plan administrator will adjust the number and type of common units with respect to which future Awards may be granted under the 2021 Plan. Upon the occurrence of a similar event that would not result in a FASB ASC Topic 718 accounting charge if adjustments to Awards were discretionary, the plan administrator shall have complete discretion to adjust Awards in the manner it deems appropriate. In the event the plan administrator makes any such adjustments, a corresponding and proportionate adjustment shall be made with respect to the maximum number of common units available under the 2021 Plan and the kind of units or other securities available for grant under the 2021 Plan.

Omnibus Agreement

In connection with the Simplification Transactions completed in November 2016, we entered into an omnibus agreement (the “Omnibus Agreement”) with PAGP, PAGP GP, Plains AAP, PAA GP LLC and GP LLC (collectively with us, the “Plains Entities”), which provides, among other things, that all direct or indirect expenses of any of the Plains Entities will be paid by us, other than income taxes, if any, of PAGP GP, PAGP, GP LLC, Plains AAP and PAA GP LLC. Such direct or indirect expenses include, but are not limited to (i) compensation and expense reimbursements for the directors of PAGP GP, (ii) director and officer liability insurance, (iii) listing exchange fees, (iv) investor relations expenses, and (v) fees related to legal, tax, financial advisory and accounting services. We paid $4.4 million of such expenses in 2022.

Other

During 2022, we purchased approximately $8.2 million of petroleum products from companies affiliated with EMG. These ordinary course transactions were conducted at prices that we believe

TABLE OF CONTENTS

approximate market. Based on our knowledge, the amounts received during 2022 from PAA by companies affiliated with EMG ($8.2 million) did not exceed 5% of EMG’s consolidated gross revenues.

During 2022, we purchased approximately $65 million of petroleum products from companies affiliated with EnCap. These ordinary course transactions were conducted at prices that we believe approximate market. Based on our knowledge, the amounts received during 2022 from PAA by companies affiliated with EnCap ($65 million) did not exceed 5% of EnCap’s consolidated gross revenues.

An employee in our marketing department, who has been with PAA for approximately 15 years, is the daughter of Willie Chiang, our Chief Executive Officer. Mr. Chiang’s daughter’s total compensation for 2022 was approximately $200,000.

Review, Approval or Ratification of Transactions with Related Persons

Pursuant to our Governance Guidelines, a director is expected to bring to the attention of the CEO or the Board any conflict or potential conflict of interest that may arise between the director or any affiliate of the director, on the one hand, and PAGP GP, PAA, PAGP or their respective affiliates, on the other. The resolution of any such conflict or potential conflict should, at the discretion of the Board in light of the circumstances, be determined by a majority of the disinterested directors.

If a conflict or potential conflict of interest arises between PAA and its limited partners, on the one hand, and our general partner and its owners and affiliates, on the other, the resolution of any such conflict or potential conflict should be addressed by the Board in accordance with the applicable provisions of the partnership agreements of PAA and PAGP. At the discretion of the Board in light of the circumstances, the resolution may be determined by the Board or by a “conflicts committee” meeting the definitional requirements for such a committee under the partnership agreements.

Pursuant to our Code of Business Conduct, any executive officer must avoid conflicts of interest unless approved by the Board.

In the case of any sale of equity by the Partnership in which an owner or affiliate of an owner of our general partner participates, our practice would be to obtain Board approval for the transaction. The Board typically delegates authority to set the specific terms to a pricing committee, consisting of the CEO and one independent director. Actions by the pricing committee require unanimous approval of such committee.

TABLE OF CONTENTS

REPORT OF THE AUDIT COMMITTEE

The Audit Committee of our Board oversees the Partnership’s financial reporting process on behalf of the Board. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls.

In fulfilling its oversight responsibilities, the Audit Committee reviewed and discussed with management the audited financial statements contained in our Annual Report on Form 10-K for the year ended December 31, 2022.

The Partnership’s independent registered public accounting firm, PricewaterhouseCoopers LLP, is responsible for expressing an opinion on the conformity of the audited financial statements with accounting principles generally accepted in the United States of America. The Audit Committee reviewed with PricewaterhouseCoopers LLP the firm’s judgment as to the quality, not just the acceptability, of the Partnership’s accounting principles and such other matters as are required to be discussed with the Audit Committee under generally accepted auditing standards.

The Audit Committee discussed with PricewaterhouseCoopers LLP the matters required to be discussed under applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”). The Audit Committee received written disclosures and the letter from PricewaterhouseCoopers LLP required by applicable requirements of the PCAOB regarding PricewaterhouseCoopers LLP’s communications with the Audit Committee concerning independence, and has discussed with PricewaterhouseCoopers LLP its independence from management and the Partnership.

Based on the reviews and discussions referred to above, the Audit Committee recommended to the Board that the audited financial statements be included in the Annual Report on Form 10-K for the year ended December 31, 2022 for filing with the SEC.

Pre-Approval Policy

Our Audit Committee reviews our external financial reporting, engages our independent auditors and reviews the adequacy of our internal accounting controls. Our Audit Committee performs similar functions on PAGP’s behalf. All services provided by our independent auditor to us or to PAGP are subject to pre-approval by our Audit Committee. The Audit Committee has instituted policies that describe certain pre-approved non-audit services. We believe that the descriptions of services are designed to be sufficiently detailed as to particular services provided, such that (i) management is not required to exercise judgment as to whether a proposed service fits within the description and (ii) the Audit Committee knows what services it is being asked to pre-approve. The Audit Committee is informed of each engagement of the independent auditor to provide services under the respective policy. All services provided by our independent auditor during the years ended December 31, 2022 and 2021 were approved in advance by our Audit Committee.

PROPOSAL 2 — RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT YOU VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF PRICEWATERHOUSECOOPERS LLP AS OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM FOR THE FISCAL YEAR ENDING DECEMBER 31, 2023.

The second proposal item to be voted on at the PAA Annual Meeting is ratification of the appointment of PricewaterhouseCoopers LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2023. Votes cast on this proposal by our Unitholders will be “passed through” as instructions to PAA as to how PAA should vote the PAGP Class C shares that it owns at the PAGP Annual Meeting on ratification of the appointment of PricewaterhouseCoopers LLP as our and PAGP’s independent registered public accounting firm for 2023.

The Audit Committee of the Board has appointed PricewaterhouseCoopers LLP to continue to act as our and PAGP’s independent registered public accounting firm for the fiscal year ending December 31, 2023. The Board has directed that such appointment be submitted to our Unitholders for ratification at the PAA Annual Meeting.

Ratification of the appointment of PricewaterhouseCoopers LLP as our and PAGP’s independent registered public accounting firm is not required. The Board, however, is submitting the appointment to our Unitholders for ratification as a good corporate governance practice. Representatives of PricewaterhouseCoopers LLP are expected to be present at the PAA Annual Meeting and will have an opportunity to make a statement if they so desire. They will also be available to respond to appropriate questions.

PROPOSAL 3 — ADVISORY VOTE TO APPROVE OUR 2022 NAMED EXECUTIVE OFFICER COMPENSATION

THE BOARD UNANIMOUSLY RECOMMENDS THAT YOU VOTE, ON A NON-BINDING ADVISORY BASIS, “FOR” THE RESOLUTION APPROVING THE 2022 COMPENSATION OF THE NAMED EXECUTIVE OFFICERS AS DESCRIBED IN THIS PROXY STATEMENT.

This proposal, commonly known as a “say-on-pay” proposal, provides our Unitholders with the opportunity to cast a pass-through advisory vote on the approval of the compensation of our Named Executive Officers.

The Board recognizes that executive compensation is an important matter for our Unitholders. As described in detail in the “Executive Compensation” section and elsewhere in this proxy statement, the Compensation Committee is tasked with the implementation of our executive compensation philosophy, and the core of that philosophy has been, and continues to be, to pay our executive officers based on performance. In particular, the Compensation Committee strives to attract, retain and motivate exceptional executives, to reward past performance measured against established goals and provide incentives for future performance, and to align executives’ long-term interests with the interests of our Unitholders. To do so, the Compensation Committee uses a combination of short- and long-term incentive compensation to reward near-term performance and to encourage executives’ commitment to our long-range, strategic business goals. It is the intention of the Compensation Committee that our executive officers be compensated competitively and consistently with our strategy, sound corporate governance principles and Unitholder interests and concerns.

As described in the Compensation Discussion and Analysis section of this proxy statement, we believe our compensation program is effective, appropriate and strongly aligned with the long-term interests of our Unitholders and that the total compensation provided to the Named Executive Officers (including potential payouts upon a termination or change of control) is reasonable and not excessive. As you consider this Proposal 3, we urge you to read the Compensation Discussion and Analysis section of this proxy statement for additional details on executive compensation, including the more detailed information about our compensation philosophy and objectives, and to review the tabular disclosures regarding Named Executive Officer compensation together with the accompanying narrative disclosures in the Executive Compensation section of this proxy statement.

The Dodd-Frank Wall Street Reform and Consumer Protection Act of 2012, as well as Section 14A of the Exchange Act, and the rules promulgated thereunder, enables our Unitholders the opportunity to express their views, on an advisory basis, on the compensation of the Named Executive Officers. This vote is not intended to address any specific item of compensation, but rather the overall compensation of the Named Executive Officers and the philosophy, policies and practices described in this proxy statement.

As an advisory vote, this Proposal 3 is not binding on the Board or the Compensation Committee, will not overrule any decisions made by the Board or the Compensation Committee or require the Board or the Compensation Committee to take any action. Although the vote is non-binding, the Board and the Compensation Committee value the opinions of our Unitholders and will carefully consider the outcome of the vote when making future compensation decisions for executive officers. In particular, to the extent there is any significant vote against the Named Executive Officers’ compensation as disclosed in this proxy statement, we will consider our Unitholders’ concerns, and the Compensation Committee will evaluate whether any actions are necessary to address those concerns.

For the reasons set forth above, the following resolution will be submitted for approval at the PAA Annual Meeting:

“RESOLVED, that the compensation paid to the Named Executive Officers during and with respect to the calendar year ended December 31, 2022, as disclosed pursuant to Item 402 of Regulation S-K in PAA’s proxy statement for its 2023 Annual Meeting of Unitholders, including the Compensation Discussion and Analysis, compensation tables and accompanying narrative discussion, is hereby approved.”

TABLE OF CONTENTS

OTHER MATTERS FOR THE PAA ANNUAL MEETING

We know of no matters to be acted upon at the PAA Annual Meeting other than the proposals included in the accompanying notice and described in this proxy statement. If any other matter requiring a vote of Unitholders arises, including a question of adjourning the PAA Annual Meeting, the persons named as proxies in the proxy card will have the discretion to vote thereon according to their best judgment of what they consider to be in the best interests of PAA. The proxy card confers discretionary authority to take action with respect to any additional matters that may come before the meeting or any adjournment thereof.

DIRECTOR NOMINATIONS AND UNITHOLDER PROPOSALS FOR THE 2024 ANNUAL MEETING

PAGP GP Director Nominations

Pursuant to Section 13.13 of our partnership agreement, any eligible Unitholder who owns common units equal in number to 10% or more of the outstanding Class A, Class B and Class C shares of PAGP, taken together as a single class, is entitled to direct our general partner to cause us to nominate one person for election as a PAGP Eligible Director in accordance with Section 13.4(c)(ii) of PAGP’s partnership agreement. Eligible Unitholders who wish to submit a director nomination for our 2024 annual meeting must deliver written notice thereof to our principal executive offices in care of the Corporate Secretary by mail to 333 Clay Street, Suite 1600, Houston, Texas 77002 no later than the close of business on February 24, 2024, nor earlier than the close of business on January 25, 2024. In the event that the date of the 2024 annual meeting is changed by more than 30 days before or more than 60 days after the one-year anniversary of the 2023 annual meeting, Unitholder notice of a director nomination must be received no earlier than the close of business on the 120th day prior to the 2024 annual meeting and not later than the close of business on the date that is the later of the (i) 90th day prior to the 2024 annual meeting or (ii) if the first public announcement of the 2024 annual meeting is less than 100 days prior to such meeting, the 10th day following the day on which public announcement of the date of the 2024 annual meeting is first made.

The written notice must comply with Section 13.13 of our partnership agreement and the procedures set forth in Section 13.4(c)(ii) of PAGP’s partnership agreement, including the informational requirements included in Section 13.4(c)(ii)(A)(3). We will not entertain any nomination at the PAA Annual Meeting that does not meet the requirements set forth in our partnership agreement and PAGP’s partnership agreement. Our partnership agreement is filed as Exhibit 3.1 to our Current Report on Form 8-K filed on October 12, 2017, and PAGP’s partnership agreement is filed as Exhibit 3.2 to our Current Report on Form 8-K filed on November 21, 2016.

In addition to satisfying the requirements under our partnership agreement and PAGP’s partnership agreement as described in the immediately preceding paragraph, to comply with the universal proxy rules under the Exchange Act, any eligible Unitholder who intends to solicit proxies in support of director nominees other than our nominees must provide written notice that sets forth the information required by Rule 14a-19 under the Exchange Act no later than March 25, 2024. However, if the date of the 2024 annual meeting is more than 30 days before or after the anniversary of the date of the 2023 annual meeting, then such written notice must be delivered by the later of (i) the tenth day following the public announcement of the date of the 2024 annual meeting is first made and (ii) the date that is 60 days prior to the date of the 2024 annual meeting.

Unitholder Proposals

Any Unitholder who, in accordance with Rule 14a-8 under the Exchange Act, wishes to submit a proposal for inclusion in our proxy statement for the 2024 annual meeting must submit their proposal in writing, along with proof of eligibility, to our principal executive offices in care of the Corporate Secretary by mail to 333 Clay Street, Suite 1600, Houston, Texas 77002. Proposal submissions must be received no later than the close of business (5:00 p.m. Central Time) on December 16, 2023, to be considered timely. SEC rules set forth standards as to what proposals are required to be included in a proxy statement for a meeting. In no event are Unitholders allowed to vote on matters that would cause the Unitholders to be deemed to take part in the management and control of our business and affairs so as to jeopardize

TABLE OF CONTENTS

such Unitholder’s limited liability under the Delaware limited partnership act or the law of any other state in which we are qualified to do business.

HOUSEHOLDING MATTERS

In some cases, Unitholders who share a single address will receive only one annual report and one proxy statement at that address unless we have received instructions to the contrary from any Unitholder at that address. This practice, known as “householding,” is designed to reduce our printing and postage costs. However, if a Unitholder of record residing at such an address wishes to receive a separate copy of our annual report or proxy statement or future annual reports or proxy statements (as applicable), he or she may contact our Corporate Secretary at (713) 646-4100, or write to Plains All American Pipeline, L.P., 333 Clay Street, Suite 1600, Houston, Texas 77002, attention: Corporate Secretary. We will deliver separate copies of our annual report or proxy statement promptly upon written or oral request. If you are a Unitholder of record receiving multiple copies of our annual report or proxy statement, you can request householding by contacting us in the same manner. If you own your Units through a bank, broker or other Unitholder of record, you can request additional copies of the annual report or proxy statement or request householding by contacting the Unitholder of record (i.e., your bank or broker).
