HOUSTON, January 7, 2025 /PRNewswire/ -- Summit Midstream Corporation (NYSE: SMC) (“SMC” or the “Company”) announced today that Summit Midstream Holdings, LLC (the “Issuer”), which is a subsidiary of the Company, has commenced an offering (the “Offering”) of $250.0 million in aggregate principal amount of additional 8.625% Senior Secured Second Lien Notes due 2029 (the “Additional Notes”). The Additional Notes will be issued under the same indenture as the Issuer’s $575.0 million in aggregate principal amount of 8.625% Senior Secured Second Lien Notes due 2029 (the “Existing Notes”), will have substantially identical terms as the Existing Notes, other than the issue date and issue price, and will form a single series and vote together with the Existing Notes. The Company intends to use the net proceeds from the Offering to (i) repay a portion of the outstanding borrowings under the Company’s asset-based lending credit facility (the “ABL Facility”) and (ii) for general corporate purposes, including to pay fees and expenses associated with the Offering.

The Additional Notes will be guaranteed on a senior second-priority basis by the Company and certain of the Company’s existing and future subsidiaries and will initially be secured on a second-priority basis by the same collateral that is pledged for the benefit of the Company’s lenders under the ABL Facility.

The Additional Notes and the related guarantees are being offered only to persons reasonably believed to be qualified institutional buyers pursuant to Rule 144A under the Securities Act of 1933, as amended (the “Securities Act”), and to non-U.S. persons outside the United States only in compliance with Regulation S under the Securities Act. The offer and sale of the Additional Notes and the related guarantees have not been registered under the Securities Act or any state securities laws and may not be offered or sold in the United States absent registration or an applicable exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.

This press release does not constitute an offer to sell or the solicitation of an offer to buy any security, nor shall there be any sale of the Additional Notes and the related guarantees or any other security of the Company, in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to the registration or qualification under the securities laws of any such jurisdiction. Any offers of the Additional Notes will be made only by means of a private offering memorandum.
