(together with the Partnership, the “Issuers”), intend to offer $350.0 million in aggregate principal amount of senior unsecured notes due 2031 (the “Notes”) in a private placement to eligible purchasers (the “Offering”). In connection with the Offering, the Company is providing certain information regarding the Company to prospective investors in a preliminary offering memorandum, dated January 6, 2026, and such information is furnished as Exhibit 99.1 hereto. The Company intends to use the net proceeds from the Offering, together with cash on hand and borrowings under its revolving credit facility, to redeem all of the Issuers’ outstanding 11.00% Senior Notes due 2026 on or around January 21, 2026 and $275.0 million aggregate principal amount of the Issuers’ outstanding 8.125% Senior Notes due 2027 on or around January 16, 2026.

In accordance with General Instruction B.2 of Form 8-K, the information contained in this Item 7.01, including Exhibit 99.1, shall not be deemed “filed” for the purpose of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall such information and Exhibit 99.1 be deemed incorporated by reference into any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as shall be expressly set forth by specific reference in such filing.

The Notes will not be registered under the Securities Act or any state securities law and may not be offered or sold in the United States absent registration or an applicable exemption from registration under the Securities Act and applicable state securities laws.
