As of June 30, 2025, the Partnership had no amount drawn under its $600.0 million accounts receivable securitization facility (the “Securitization Facility”), resulting in $600.0 million of remaining availability. In July 2025, the Partnership amended the Securitization Facility to, among other things, extend the facility termination date to August 31, 2026.

We guarantee all of the Partnership’s outstanding senior unsecured notes.

In June 2025, we completed an underwritten public offering of (i) $750.0 million aggregate principal amount of our 4.900% Senior Unsecured Notes due 2030 and (ii) $750.0 million aggregate principal amount of our 5.650% Senior Unsecured Notes due 2036, resulting in net proceeds of approximately $1.5 billion. The net proceeds were initially used to reduce borrowings under the Securitization Facility and Commercial Paper Program as reflected on the balance sheet as of June 30, 2025. A conditional notice of redemption of all of the Partnership’s 6.500% Senior Unsecured Notes due 2027 was issued in June 2025, resulting in the classification of the notes within Current debt obligations on our Consolidated Balance Sheets as of June 30, 2025. In July 2025, we used borrowings under the Securitization Facility and Commercial Paper Program to fund the redemption of all of the Partnership’s 6.500% Senior Unsecured Notes due 2027.

In February 2025, we entered into a new $3.5 billion TRGP senior revolving credit facility (the “TRGP Revolver”), which matures in February 2030. In connection with our entry into the TRGP Revolver, we terminated our previous TRGP senior revolving credit facility (the “Previous TRGP Revolver”). We maintain an unsecured commercial paper note program (the “Commercial Paper Program”), the borrowings of which are supported through maintaining a minimum available borrowing capacity under the TRGP Revolver equal to the aggregate amount outstanding under the Commercial Paper Program at any one time not to exceed $3.5 billion. The TRGP Revolver had no borrowings outstanding and the Commercial Paper Program had $667.0 million of borrowings outstanding, resulting in approximately $2.8 billion of available liquidity as of June 30, 2025, after accounting for outstanding letters of credit.

In February 2025, we completed an underwritten public offering of (i) $1.0 billion aggregate principal amount of our 5.550% Senior Unsecured Notes due 2035 and (ii) $1.0 billion aggregate principal amount of our 6.125% Senior Unsecured Notes due 2055, resulting in net proceeds of approximately $2.0 billion.

As of June 30, 2025, we were in compliance with the covenants contained in our various debt agreements.

In February 2025, we entered into a Credit Agreement with Bank of America, N.A., as the Administrative Agent and Swing Line Lender, the letter of credit issuers party thereto and the other lenders party thereto. The TRGP Revolver provides for a revolving credit facility in an initial aggregate principal amount up to $3.5 billion (with an option to increase such maximum aggregate principal amount by up to $500.0 million in the future, subject to the terms of the TRGP Revolver) and a swing line sub-facility of up to $150.0 million. We recorded $8.9 million of debt issuance costs related to the TRGP Revolver in Other long-term assets on our Consolidated Balance Sheets. The TRGP Revolver matures on February 18, 2030. We will be able to extend the maturity date, subject to the required lenders’ consent, by one year up to two times. In connection with our entry into the TRGP Revolver, we terminated the Previous TRGP Revolver. As a result of the termination of the Previous TRGP Revolver, we recorded a loss due to debt extinguishment of $0.6 million.

In February 2025, we completed an underwritten public offering of (i) $1.0 billion aggregate principal amount of our 5.550% Senior Unsecured Notes due 2035 (the “5.550% Notes due 2035”) and (ii) $1.0 billion aggregate principal amount of our 6.125% Senior Unsecured Notes due 2055 (the “6.125% Notes due 2055”) (collectively, the “February 2025 Senior Unsecured Notes”), resulting in net proceeds of approximately $2.0 billion. The February 2025 Senior Unsecured Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by our subsidiaries that guarantee the TRGP Revolver, so long as such subsidiary guarantors satisfy certain conditions. The February 2025 Senior Unsecured Notes were issued pursuant to the Indenture, dated as of April 6, 2022, as supplemented by that certain Tenth Supplemental Indenture, dated as of February 27, 2025, among us, each subsidiary guarantor and U.S. Bank Trust Company, National Association, as trustee. In connection with the offering, we recorded debt issuance costs of $20.4 million and discount of $6.1 million as reductions to the carrying value of the February 2025 Senior Unsecured Notes in Long-term debt on our Consolidated Balance Sheets. We used the net proceeds from the debt issuance to fund the Badlands Transaction and the remaining net proceeds for general corporate purposes, including to repay borrowings under the Commercial Paper Program.

In June 2025, we completed an underwritten public offering of (i) $750.0 million aggregate principal amount of our 4.900% Senior Unsecured Notes due 2030 (the “4.900% Notes due 2030”) and (ii) $750.0 million aggregate principal amount of our 5.650% Senior Unsecured Notes due 2036 (the “5.650% Notes due 2036”) (collectively, the “June 2025 Senior Unsecured Notes”), resulting in net proceeds of approximately $1.5 billion. The June 2025 Senior Unsecured Notes are fully and unconditionally guaranteed, jointly and severally, on a senior unsecured basis by our subsidiaries that guarantee the TRGP Revolver, so long as such subsidiary guarantors satisfy certain conditions. The June 2025 Senior Unsecured Notes were issued pursuant to the Indenture, dated as of April 6, 2022, as supplemented by that certain Eleventh Supplemental Indenture, dated as of June 18, 2025, among us, each subsidiary guarantor and U.S. Bank Trust Company, National Association, as trustee. In connection with the offering, we recorded debt issuance costs of $13.5 million and discount of $3.2 million as reductions to the carrying value of the June 2025 Senior Unsecured Notes in Long-term debt on our Consolidated Balance Sheets. The net proceeds were initially used to reduce borrowings under the Securitization Facility and Commercial Paper Program as reflected on the balance sheet as of June 30, 2025. In July 2025, we used borrowings under the Securitization Facility and Commercial Paper Program to fund the redemption of all of the Partnership’s 6.500% Senior Unsecured Notes due 2027 (the “6.500% Notes due 2027”).

A conditional notice of redemption of all of the 6.500% Notes due 2027 was issued in June 2025, with the redemption conditioned on completion of the June 2025 Senior Unsecured Notes issuance, resulting in the classification of the 6.500% Notes due 2027 within Current debt obligations on our Consolidated Balance Sheets as of June 30, 2025. In July 2025, we completed the redemption of all of the Partnership’s 6.500% Notes due 2027 and recorded a debt extinguishment loss of $1.9 million due to a write-off of debt issuance costs in the third quarter.

In July 2025, the Partnership amended the Securitization Facility to, among other things, extend the facility termination date to August 31, 2026.
