Houston, Texas (October 19, 2021) - Summit Midstream Partners, LP (NYSE: SMLP) (the "Partnership") announced today that Summit Midstream Holdings, LLC, a Delaware limited liability company ("Summit Holdings"), and Summit Midstream Finance Corp., a Delaware corporation (together with Summit Holdings, the "Co-Issuers"), which are subsidiaries of the Partnership, priced a private offering (the "Offering") of $700,000,000 aggregate principal amount of 8.50% Senior Secured Second Lien Notes due 2026 (the "Notes") at a price of 98.5% of their face value. The Notes will pay interest semi-annually on April 15 and October 15 of each year, commencing on April 15, 2022, and will be jointly and severally guaranteed, on a senior second-priority secured basis, by the Partnership and each restricted subsidiary of the Partnership (other than the Co-Issuers) that is an obligor under the credit agreement by and among Summit Holdings, as borrower, Bank of America, N.A., administrative agent and trustee and the several lenders and other agents party thereto (the "ABL Credit Agreement"), which Summit Holdings expects to enter into on or about the date on which the Notes are issued, or under the Co-Issuers' 5.75% Senior Notes due 2025 (the "2025 Notes") on the issue date of the Notes.

The Notes will mature on October 15, 2026; provided that, if the outstanding amount of the 2025 Notes is greater than or equal to $50.0 million on January 14, 2025, which is 91 days prior to the scheduled maturity date of the 2025 Notes, then the Notes will mature on January 14, 2025. The Offering is expected to close on November 2, 2021, subject to customary closing conditions.

The Co-Issuers intend to use the net proceeds from the Offering, together with cash on hand and borrowings under the ABL Credit Agreement to (i) repay in full all of Summit Holdings' obligations under the Third Amended and Restated Credit Agreement, dated as of May 26, 2017 (as amended or otherwise modified from time to time), among Summit Holdings, the lenders from time to time party thereto and Wells Fargo Bank, National Association, as administrative agent and collateral agent (the "Revolving Credit Facility"), (ii) fund the previously announced conditional redemption of all of the $234,047,000 in aggregate principal amount outstanding of the Co-Issuers' 5.50% Senior Notes due 2022 (the "2022 Notes"), (iii) pay accrued and unpaid interest on the Revolving Credit Facility and 2022 Notes and (iv) for general corporate purposes, including fees and expenses associated with the Offering.

The Co-Issuers intend to redeem all of the 2022 Notes at a redemption price equal to 100.0% of the principal amount of the 2022 Notes, plus accrued and unpaid interest on November 12, 2021. The Co-Issuers expect net cash proceeds from the Offering, together with cash on hand and borrowings under the ABL Credit Agreement, after repayment of the Revolving Credit Facility, to be sufficient to pay the redemption price, all accrued and unpaid interest and all other amounts owing under the indenture governing the 2022 Notes.

The Notes and related guarantees are being offered only to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act of 1933, as amended (the "Securities Act"), or to persons other than "U.S. persons" outside the United States in compliance with Regulation S under the Securities Act. The Notes and related guarantees have not been registered under the Securities Act or the securities laws of any other jurisdiction and may not be offered or sold in the United States absent registration or an applicable exemption from the registration requirements. This press release does not constitute an offer to sell any security, including the Notes, nor a solicitation for an offer to purchase any security, including the Notes, and shall not constitute an offer, solicitation or sale in any jurisdiction in which such offering, solicitation or sale would be unlawful.
