Note 10—Debt

Debt consisted of the following (in millions):

(1)PAA classified these commercial paper notes as short-term as of December 31, 2024 and 2023, as these notes were primarily designated as working capital borrowings, were required to be repaid within one year and were primarily for hedged NGL and crude oil inventory and NYMEX and ICE margin deposits.

(2)As of December 31, 2023, PAA classified its $750 million,3.60% senior notes due November 2024 as long-term based on its ability and intent to refinance these notes on a long-term basis at that time. PAA redeemed these senior notes on November 1, 2024.

(3)As of December 31, 2024, PAA classified its $1 billion,4.65% senior notes due October 2025 as long-term based on its ability and intent to refinance these notes on a long-term basis.

(4)PAA’s fixed-rate senior notes had a face value of approximately $7.2 billion and $7.3 billion at December 31, 2024 and 2023, respectively. We estimated the aggregate fair value of these notes to be approximately $6.7 billion and $6.9 billion at December 31, 2024 and 2023, respectively. PAA’s fixed-rate senior notes are traded among institutions, and these trades are routinely published by a reporting service. Our determination of fair value is based on reported trading activity near the end of the reporting period. We estimate that the carrying value of outstanding borrowings under PAA’s commercial paper program approximates fair value as interest rates reflect current market rates. The fair value estimates for the PAA senior notes and commercial paper program are based upon observable market data and are classified in Level 2 of the fair value hierarchy.

PAA Commercial Paper Program

PAA has a commercial paper program under which it may issue (and have outstanding at any time) up to $2.7 billion in the aggregate of privately placed, unsecured commercial paper notes. Such notes are backstopped by the PAA senior unsecured revolving credit facility and the PAA senior secured hedged inventory facility; as such, any borrowings under the PAA commercial paper program reduce the available capacity under these facilities.

Credit Agreements

PAA senior secured hedged inventory facility. PAA has a credit agreement that provides for a senior secured hedged inventory facility with a committed borrowing capacity of $1.35 billion. Subject to obtaining additional or increased lender commitments and other terms and conditions, the committed capacity of the facility may be increased to $1.9 billion. The credit agreement provides for the issuance of letters of credit of up to $400 million. Proceeds from the facility are primarily used to finance purchased or stored hedged inventory, including NYMEX and ICE margin deposits. Such obligations under the committed facility are secured by the financed inventory and the associated accounts receivable and are repaid from the proceeds of the sale of the financed inventory. Borrowings accrue interest based, at our election, on certain floating rate indices as defined in the credit agreement, in each case plus a margin based on our credit rating at the applicable time. The amended credit agreement also provides forone or moreone-year extensions, subject to applicable approval and other terms and conditions. In August 2024, PAA amended the facility agreement to, among other things, extend the maturity date of the facility to August 2027 for each extending lender. The maturity date with respect to the non-extending lender (which represents a commitment of approximately $64 million out of total commitments of $1.35 billion from all lenders) remains August 2026.

PAA senior unsecured revolving credit facility. PAA has a credit agreement that provides for a senior unsecured revolving credit facility with a committed borrowing capacity of $1.35 billion, of which $400 million is available for the issuance of letters of credit. Subject to obtaining additional or increased lender commitments and other terms and conditions, the committed capacity may be increased to $2.1 billion. Borrowings accrue interest based, at our election, on certain floating rate indices as defined in the credit agreement, in each case plus a margin based on our credit rating at the applicable time. The credit agreement provides forone or moreone-year extensions, subject to applicable approval and other terms and conditions. In August 2024, PAA amended the facility agreement to, among other things, extend the maturity date of the facility to August 2029 for each extending lender. The maturity date with respect to the non-extending lender (which represents a commitment of approximately $64 million out of total commitments of $1.35 billion from all lenders) remains August 2027.

PAA Senior Notes

PAA’s senior notes are co-issued, jointly and severally, by Plains All American Pipeline, L.P. and a 100%-owned consolidated finance subsidiary (neither of which have independent assets or operations) and are unsecured senior obligations of such entities and rank equally in right of payment with existing and future senior indebtedness of the issuers. PAA may, at its option, redeem any series of senior notes at any time in whole or from time to time in part, prior to maturity, at the redemption prices described in the indentures governing the senior notes. PAA’s senior notes are not guaranteed by any of its subsidiaries.

PAA Senior Notes Issuances. The table below summarizes PAA’s issuances of senior unsecured notes during the three years ended December 31, 2024 (in millions):

In January 2025, PAA also completed the offering of $1 billion,5.95% senior notes due June 2035 at a public offering price of 99.761%. Interest payments are due on June 15 and December 15 of each year, commencing on June 15, 2025.

PAA Senior Notes Repayments. During the three years ended December 31, 2024, PAA repaid the following senior unsecured notes in full (in millions):

(1)PAA repaid these senior notes with proceeds from its 5.70% senior notes issued in June 2024, cash on hand and borrowings under its commercial paper program.

(2)PAA repaid these senior notes with cash on hand and borrowings under its commercial paper program.

Maturities

The weighted average maturity of PAA’s senior notes outstanding at December 31, 2024 was approximately 10 years. The following table presents the aggregate contractually scheduled maturities of such senior notes for the next five years and thereafter. The amounts presented exclude unamortized discounts and debt issuance costs.

Covenants and Compliance

The credit agreements for PAA’s revolving credit facilities (which impact the ability to access the PAA commercial paper program because they provide the financial backstop that supports PAA’s short-term credit ratings) and the indentures governing PAA’s senior notes contain cross-default provisions. PAA’s credit agreements prohibit declaration or payments of distributions on, or purchases or redemptions of, units if any default or event of default is continuing. In addition, PAA’s agreements contain various covenants limiting PAA’s ability to, among other things:

•grant liens on certain property;

•incur indebtedness, including finance leases;

•sell substantially all of its assets or enter into a merger or consolidation;

•engage in certain transactions with affiliates; and

•enter into certain burdensome agreements.

The credit agreements for the PAA senior unsecured revolving credit facility and senior secured hedged inventory facility treat a change of control as an event of default and also require PAA to maintain a debt-to-EBITDA coverage ratio that, on a trailing four-quarter basis, will not be greater than 5.00 to 1.00 (or 5.50 to 1.00 on all outstanding debt during an acquisition period (generally, the period consisting of three fiscal quarters following an acquisition greater than $150 million)). For covenant compliance purposes, Consolidated EBITDA may include certain adjustments, including those for material projects and certain non-recurring expenses. Additionally, letters of credit and borrowings to fund hedged inventory and margin requirements are excluded when calculating the debt coverage ratio.

A default under PAA’s credit agreements or indentures would permit the lenders to accelerate the maturity of the outstanding debt. As long as PAA is in compliance with the provisions contained in its credit agreements, PAA’s ability to make distributions of available cash is not restricted. As of December 31, 2024, PAA was in compliance with the covenants contained in its credit agreements and indentures.

Borrowings and Repayments

Total borrowings under PAA’s credit facilities and commercial paper program for the years ended December 31, 2024, 2023 and 2022 were approximately $28.1 billion, $18.1 billion and $25.0 billion, respectively. Total repayments under PAA’s credit facilities and commercial paper program were approximately $28.1 billion, $17.7 billion and $25.0 billion for the years ended December 31, 2024, 2023 and 2022, respectively. The variance in total gross borrowings and repayments is impacted by various business and financial factors including, but not limited to, the timing, average term and method of general partnership borrowing activities.

Letters of Credit

In connection with our merchant activities, we provide certain suppliers with irrevocable standby letters of credit to secure our obligation for the purchase and transportation of crude oil and NGL. Our liabilities with respect to these purchase obligations are recorded in accounts payable on our balance sheet in the month the crude oil or NGL is purchased. Generally, these letters of credit are issued for periods of up toseventy days and are terminated upon completion of each transaction. Additionally, we issue letters of credit to support insurance programs, derivative transactions, including hedging-related margin obligations, and construction activities. At December 31, 2024 and 2023, we had outstanding letters of credit of $90 million and $205 million, respectively.

Debt Issuance Costs

Costs incurred in connection with the issuance of senior notes are recorded as a direct deduction from the related debt liability and are amortized using the straight-line method over the term of the related debt. Use of the straight-line method does not differ materially from the “effective interest” method of amortization.
