Material Changes and Use of Proceeds
The primary material change is the addition of $1.2 billion in long-term senior indebtedness. The net proceeds from the offering are designated for the following purposes:
- Repayment of maturing 4.650% Senior Notes due 2026.
- Repayment of amounts outstanding under the commercial paper program, including borrowings used to fund the cash consideration for the acquisition of Aris Water Solutions, Inc.
- General partnership purposes, including funding capital expenditures.
Management Commentary, Risks, and Covenants
The Notes rank equally with existing senior indebtedness and senior to subordinated debt. The Indenture includes covenants limiting the ability to create liens on principal properties, engage in sale and leaseback transactions, or merge/consolidate without compliance. Initially, the Notes are not guaranteed by subsidiaries, though guarantees may be triggered if subsidiaries become borrowers or guarantors under the revolving credit facility.
Events of default include failure to pay interest or principal, failure to comply with covenants after notice, and bankruptcy or insolvency events. Upon default, the principal and accrued interest may become immediately due and payable.
