The Issuers intend to use the net proceeds from the offering of the Notes and borrowings under Antero Midstream Partners’ credit facility to redeem of all of their 5.375% senior notes due 2024 (the “2024 Notes”) outstanding on June 8, 2021 at a redemption price of 102.688% of the principal amount thereof, plus accrued and unpaid interest. As of May 21, 2021, there was $650.0 million aggregate principal amount of the 2024 Notes outstanding.

The securities to be offered have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state or jurisdiction securities laws, and unless so registered, the securities may not be offered or sold in the United States except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state or jurisdiction securities laws.
