Antero Resources Announces Launch of $500 Million Offering of Senior Notes

Denver, Colorado, January 11, 2021—Antero Resources Corporation (NYSE: AR) (“Antero Resources”) announced today that, subject to market conditions, it intends to offer $500 million in aggregate principal amount of senior unsecured notes due 2029 (the “Notes”) in a private placement to eligible purchasers.

Antero Resources intends to use a portion of the net proceeds from the offering to fund the redemption of all $310.5 million aggregate principal amount of its 5.125% senior notes due 2022 (the “2022 Notes”) not previously called for redemption at par plus accrued interest and to use the remaining net proceeds to repay borrowings under its credit facility. The redemption of all 2022 Notes not previously called for redemption is expected to be conditioned on the completion of the offering of the Notes. The offering of the Notes is not contingent upon the completion of such redemption.

The Notes to be offered have not been registered under the Securities Act of 1933, as amended (the “Securities Act”), or any state securities laws, and unless so registered, 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 securities laws. The Notes will be offered only to persons reasonably believed to be qualified institutional buyers in reliance on Rule 144A under the Securities Act and outside the United States pursuant to Regulation S under the Securities Act.

This press release is neither an offer to sell nor a solicitation of an offer to buy the Notes or any other securities and shall not constitute an offer to sell or a solicitation of an offer to buy, or a sale of, the Notes or any other securities in any jurisdiction in which such offer, solicitation or sale is unlawful. This press release shall not constitute a notice of redemption of the 2022 Notes.
