HOUSTON, March 27, 2024 /PRNewswire/ -- Summit Midstream Partners, LP (NYSE: SMLP) ("Summit," "SMLP" or the "Partnership") today announced that Summit Midstream Holdings, LLC ("Holdings") and Summit Midstream Finance Corp. (together with Holdings, the "Issuers"), which are subsidiaries of the Partnership, are commencing a cash tender offer (the "Excess Cash Flow Offer") to purchase up to $19,331,000 aggregate principal amount (the "Excess Cash Flow Offer Amount") of their outstanding 8.500% Senior Secured Second Lien Notes due 2026 (the "Notes") at a purchase price of 100% of the aggregate principal amount thereof, plus accrued and unpaid interest to, but not including, the purchase date.

The Excess Cash Flow Offer is being made pursuant to requirements set forth in the indenture governing the Notes (the "Indenture"), which requires, if the Partnership has Excess Cash Flow (as defined in the Indenture) for the period commencing on January 1 of each fiscal year and ending on December 31 of such fiscal year (the twelve-month period ending on each such date, an "ECF Period"), the Issuers to make an offer to all registered holders (each a "Holder" and collectively, the "Holders") of Notes to purchase the maximum principal amount of Notes that may be purchased with 100% of such Excess Cash Flow for such ECF Period; provided that no such offer is required to be made to the extent that the Excess Cash Flow for such ECF Period is less than $5,000,000 (subject to an aggregate amount of excluded Excess Cash Flow for all ECF Periods of $10,000,000).

The Partnership had Excess Cash Flow exceeding $5,000,000 for the ECF Period ending December 31, 2023.

The Excess Cash Flow Offer will expire at 5:00 p.m., New York City time, on April 24, 2024, unless extended or the Excess Cash Flow Offer is earlier terminated by the Issuers, in their sole discretion. If the Notes in an aggregate principal amount in excess of the Excess Cash Flow Offer Amount are tendered pursuant to the Excess Cash Flow Offer, the Issuers will purchase Notes having an aggregate principal amount equal to the Excess Cash Flow Offer Amount on a pro rata basis from tendering Holders in accordance with the Indenture.

To the extent that the aggregate principal amount of Notes tendered pursuant to the Excess Cash Flow Offer is less than the Excess Cash Flow Offer Amount, the Issuers may use any remaining Excess Cash Flow Offer Amount for any purpose not otherwise prohibited by the Indenture.

The Excess Cash Flow Offer is being made pursuant to an Offer to Purchase, dated the date hereof (the "Offer to Purchase"), which sets forth the complete terms and conditions of the Excess Cash Flow Offer. The Excess Cash Flow Offer is made only by and pursuant to the terms set forth in the Offer to Purchase, and the information in this press release is qualified by reference to such document. Subject to applicable law, the Issuers may amend, extend or terminate the Excess Cash Flow Offer.

This press release is for informational purposes only and is neither an offer to purchase nor a solicitation of an offer to sell any Notes.

THE EXCESS CASH FLOW OFFER IS BEING MADE ONLY PURSUANT TO THE OFFER TO PURCHASE THAT THE ISSUERS WILL DISTRIBUTE TO THEIR NOTEHOLDERS AND NOTEHOLDERS SHOULD READ CAREFULLY THE OFFER TO PURCHASE BECAUSE IT CONTAINS IMPORTANT INFORMATION, INCLUDING THE VARIOUS TERMS OF, AND CONDITIONS TO, THE EXCESS CASH FLOW OFFER.
