On June 16, 2026, Antero Resources Corporation (the “Company”) established a commercial paper program (the “Program”) pursuant to which the Company may issue short-term, unsecured commercial paper notes (the “Notes”) pursuant to the exemption from registration requirements of the Securities Act of 1933, as amended (the “Securities Act”) contained in Section 4(a)(2) thereof. Notes under the Program may be issued and redeemed from time to time, with the aggregate face or principal amount of the Notes outstanding under the Program at any time not to exceed $1.65 billion, unless such amount is increased in accordance with the terms of each Commercial Paper Dealer Agreement (as defined herein). The net proceeds of the issuances of the Notes are expected to be used for general corporate purposes, including but not limited to, funding working capital, capital expenditures, acquisitions and repayment of other indebtedness.

The Notes will be sold under customary market terms in the U.S. commercial paper market at a discount from par or at par and bear interest at rates determined at the time of issuance. The maturities of the Notes may vary, but shall not exceed 397 days from the date of issuance. It is expected that the Company’s senior unsecured revolving credit facility will serve as a liquidity backstop for any issuances under the Program. The Company intends to maintain available capacity under its senior unsecured revolving credit facility in an amount at least equal to the aggregate outstanding borrowings under the Program. As of the date of this Current Report on Form 8-K, the Company has not issued any Notes.

One or more commercial paper dealers will each act as a dealer under the Program (each, a “Dealer” and collectively, the “Dealers”) pursuant to the terms and conditions of the respective commercial paper dealer agreement entered into between the Company and each Dealer (each, a “Commercial Paper Dealer Agreement” and collectively, the “Commercial Paper Dealer Agreements”). A national bank will act as the issuing and paying agent under the Program, pursuant to the terms of an issuing and paying agent agreement.

Each Commercial Paper Dealer Agreement provides the terms under which the respective Dealer will either purchase from the Company or arrange for the sale by the Company of the Notes. Each Commercial Paper Dealer Agreement contains customary representations, warranties, covenants and indemnification provisions. The foregoing description of the Commercial Paper Dealer Agreements is not complete and is subject to and qualified in its entirety by reference to the form of Commercial Paper Dealer Agreement, a copy of which is included as Exhibit 10.1 to this Current Report on Form 8-K and is incorporated herein by reference.

From time to time, the Dealers and certain of their respective affiliates have provided, and may in the future provide, lending, commercial banking, investment banking and other financial advisory services to the Company and its affiliates for which such Dealers have received or will receive customary fees and expenses.

The Notes have not been, and will not be, 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 the registration requirements of the Securities Act and applicable state securities laws. The information contained in this Current Report on Form 8-K is neither an offer to sell nor a solicitation of an offer to buy any Notes.

The information contained in Item 1.01 is incorporated by reference into this Item 2.03.
