Indenture financial
"The terms of the Notes are governed by the Indenture, dated as of May 18, 2011"
An indenture is a legal agreement between a company that borrows money by issuing bonds and the people who buy those bonds. It explains the rules the company must follow, like paying back the money and keeping certain financial promises. This document helps both sides understand their rights and responsibilities.
Senior Notes financial
"completed the public offering of $700,000,000 aggregate principal amount of 5.700% Senior Notes due 2036"
Senior notes are a type of loan that a company borrows from investors, promising to pay it back with interest. They are called "senior" because in case the company faces financial trouble, these lenders are paid back before others. This makes senior notes safer for investors compared to other types of loans or bonds.
revolving credit facility financial
"if any of WES Operating’s subsidiaries becomes a borrower or guarantor under, or grants any lien to secure any obligations pursuant to, WES Operating’s revolving credit facility"
A revolving credit facility is a type of loan that a business can borrow from whenever it needs money, up to a set limit. It’s like having a credit card for companies—allowing them to borrow, pay back, and borrow again as needed, providing flexibility for managing cash flow or funding short-term expenses.
sale and leaseback transactions financial
"limit the ability of WES Operating and certain of its subsidiaries to create liens on its principal properties, engage in sale and leaseback transactions"
events of default financial
"The Indenture also contains customary events of default, including, among other things"
Events of default are specific breaches or failures listed in a loan, bond, or credit agreement that give lenders the right to act, such as demanding immediate repayment, raising interest rates, or taking secured assets. They matter to investors because triggering one is like setting off a financial alarm: it raises the chance of foreclosure, restructuring, or bankruptcy and can sharply reduce the value of a company’s stock or bonds and increase borrowing costs.
Underwriting Agreement financial
"entered into an Underwriting Agreement (the “Underwriting Agreement”) with TD Securities (USA) LLC, Barclays Capital Inc."
An underwriting agreement is a contract where a company selling new stocks or bonds hires financial firms to buy those securities and resell them to investors. It matters because the agreement sets the offering price, number of securities, fees and which party bears the risk if sales fall short—think of it as a promise that the sale will happen and a roadmap investors can use to understand how the new securities reach the market.

Item 1.01 Entry Into a Material Definitive Agreement.

On June 25, 2026, Western Midstream Operating, LP (“WES Operating”), a subsidiary of Western Midstream Partners, LP (NYSE: WES) (“WES”), completed the public offering of $700,000,000 aggregate principal amount of 5.700% Senior Notes due 2036 (the “Notes”).

The terms of the Notes are governed by the Indenture, dated as of May 18, 2011 (the “Base Indenture”), by and among WES Operating, the subsidiary guarantors named therein and Computershare Trust Company, National Association (successor to Wells Fargo Bank, National Association), as trustee (the “Trustee”), as supplemented by the Sixteenth Supplemental Indenture (the “Supplemental Indenture”), dated as of June 25, 2026, by and between WES Operating and the Trustee, setting forth the specific terms applicable to the Notes (the Base Indenture, as supplemented by the Supplemental Indenture, the “Indenture”). Interest on the Notes will accrue from June 25, 2026, and will be payable semi-annually on January 1 and July 1 of each year, with the initial interest payment being due on January 1, 2027. The Notes will mature on July 1, 2036, unless redeemed prior to maturity. The Notes are senior unsecured obligations of the Partnership.

WES Operating may redeem all or some of the Notes, in whole or in part, at any time prior to their maturity at the redemption price as set forth in the Indenture. The Notes rank equally in right of payment with all of WES Operating’s existing and future senior indebtedness and senior to any subordinated indebtedness that WES Operating may incur.

The Indenture contains covenants that will limit the ability of WES Operating and certain of its subsidiaries to create liens on its principal properties, engage in sale and leaseback transactions, merge or consolidate with another entity or sell, lease or transfer substantially all of its properties or assets to another entity. Initially, the Notes will not be guaranteed by any of WES Operating’s subsidiaries. In the future, however, if any of WES Operating’s subsidiaries becomes a borrower or guarantor under, or grants any lien to secure any obligations pursuant to, WES Operating’s revolving credit facility, then that subsidiary will, jointly and severally, fully and unconditionally guarantee WES Operating’s payment obligations under the Notes so long as such subsidiary has any guarantee obligation under WES Operating’s revolving credit facility.

The Indenture also contains customary events of default, including, among other things, (i) default for 30 days in the payment when due of interest on the Notes; (ii) default in payment when due of principal of or premium, if any, on the Notes at maturity, upon redemption or otherwise; (iii) failure by WES Operating for 60 days after notice to comply with any of the other agreements in the Indenture; and (iv) certain events of bankruptcy or insolvency with respect to WES Operating. If an event of default occurs and is continuing with respect to any series of the Notes, the Trustee or the holders of not less than 25% in principal amount of such series of outstanding Notes may declare the principal amount of such Notes and all accrued and unpaid interest to be due and payable. Upon such a declaration, such principal amount will become due and payable immediately. If an event of default relating to certain events of bankruptcy, insolvency or reorganization with respect to WES Operating occurs and is continuing, the principal amount of such Notes outstanding will become immediately due and payable without any declaration or other act on the part of the Trustee or any holders of such Notes.

Other material terms of the Notes, the Base Indenture and the Supplemental Indenture are described in the prospectus supplement relating to the Notes, dated June 22, 2026, as filed by WES Operating with the Securities and Exchange Commission on June 23, 2026. The foregoing description of the Supplemental Indenture is qualified in its entirety by reference to the full text of the Supplemental Indenture, a copy of which is filed as Exhibit 4.1 to this Current Report on Form 8-K, and is incorporated herein by reference.
