(a) | Commercial Paper
On June 16, 2026, Antero Resources established a commercial paper program (the “Commercial Paper Program”) pursuant to which Antero Resources may issue short-term, unsecured commercial paper notes (the “Commercial Paper”). The Commercial Paper may be issued and redeemed from time to time, with the aggregate face or principal amount of the notes outstanding under the Commercial Paper Program at any time not to exceed $1.65 billion. The Commercial Paper 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 Commercial Paper may vary, but shall not exceed 397 days from the date of issuance. Antero Resources’ Credit Facility (defined below) will serve as a liquidity backstop for any issuances under the Commercial Paper Program, and therefore, Antero Resources intends to maintain available capacity under the Credit Facility in an amount at least equal to the aggregate outstanding borrowings under the Commercial Paper Program. During the second quarter of 2026, Antero Resources utilized the Commercial Paper Program to fund various short-term working capital requirements. As of June 30, 2026, Antero Resources had $182 million of outstanding Commercial Paper maturing at various dates in July 2026 with a weighted average interest rate of 4.4%.
(b) | Credit Facility
On July 30, 2024, Antero Resources entered into an amendment and restatement of its senior revolving credit facility with a syndicate of bank lenders (as amended to date, the “Credit Facility”). Borrowings are unsecured and are not guaranteed by any of Antero Resources’ subsidiaries. The Credit Facility was scheduled to mature on July 30, 2030, provided that Antero Resources could request one one-year extension of this maturity date, subject to satisfaction of certain conditions and consent of the extending lenders. However, on July 28, 2026 (the “First Amendment Effective Date”), Antero Resources entered an amendment to the Credit Facility to extend the scheduled maturity date (the “Maturity Date”) to July 30, 2031. Antero Resources may request two one-year extensions of the Maturity Date after the First Amendment Effective Date, subject to satisfaction of certain conditions and consent of the extending lenders. Commitments under the Credit Facility may be increased by up to $500 million subject to the agreement of Antero Resources, the increasing lenders, and with respect to the addition of new lenders, the consent of the Administrative Agent under the Credit Facility and the lenders with commitments to issue letters of credit under the Credit Facility. The Credit Facility contains one financial covenant requiring Antero Resources to maintain a ratio on a consolidated basis of total indebtedness to capitalization of 65% or less at the end of each fiscal quarter and other affirmative and negative covenants applicable to Antero Resources and its subsidiaries that are customary for credit facilities of this type, including, among other things, limitations on: fundamental changes such as mergers, consolidations, liquidations and dissolutions; liens; certain indebtedness; restricted payments such as dividends, distributions and equity repurchases; and material non-arms’-length transactions with its affiliates. Antero Resources was in compliance with the financial covenant under the Credit Facility as of December 31, 2025 and June 30, 2026. The Credit Facility provides for borrowing at Secured Overnight Financing Rate (“SOFR”) or an Alternate Base Rate, in each case, plus an Applicable Rate (each as defined in the Credit Facility). The Credit Facility does not amortize. Interest under the Credit Facility is payable at a variable rate based on SOFR or the Alternate Base Rate, determined by election at the time of borrowing and at the end of each applicable interest period in respect of a borrowing, plus an Applicable Rate. The Applicable Rate is determined with reference to Antero Resources’ then-current senior unsecured long-term debt rating ranging from 1.125% to 2.00% for SOFR loans. Commitment fees on the unused portion of the Credit Facility are due quarterly at rates ranging from 0.125% to 0.300%, determined with reference to Antero Resources’ then-current senior unsecured long-term debt ratings. The proceeds of the loans made under the Credit Facility may be used (i) to pay fees and expenses incurred in connection with the transactions related thereto and the refinancing of the Secured Credit Facility (defined below), (ii) to finance working capital needs and (iii) for other general corporate purposes, in each case of Antero Resources and its subsidiaries. As of December 31, 2025, Antero Resources had an outstanding balance under the Credit Facility of $439 million, with a weighted average interest rate of 5.3%, and outstanding letters of credit of $12 million. As of June 30, 2026, Antero Resources had an outstanding balance under the Credit Facility of $3 million, with a weighted average interest rate of 7.3%, and outstanding letters of credit of $12 million.
(c) | Term Loans
In connection with the signing of the HG Acquisition, Antero Resources entered into a debt commitment letter dated December 5, 2025 with a syndicate of banks (collectively, the “Banks”), pursuant to which the Banks committed, subject to satisfaction of certain customary terms and conditions, to provide Antero Resources with an unsecured 364-day term loan facility in an aggregate principal amount of $800 million (the “Term Loan Bridge Facility”) and an unsecured 3-year term loan facility in an aggregate principal amount of $1.5 billion (the “Term Loan”). As of December 31, 2025, Antero Resources had not entered into definitive agreements with respect to either of the Term Loan Bridge Facility or the Term Loan. In connection with the issuance of the 2036 Notes on January 28, 2026, Antero Resources and the Banks terminated the commitments with respect to the Term Loan Bridge Facility. On February 3, 2026, substantially concurrently with the consummation of the HG Acquisition, Antero Resources entered into the Term Loan. The Term Loan is unsecured and is not guaranteed by any of Antero Resources’ subsidiaries. The proceeds of the loans made under the Term Loan were used to (i) finance a portion of the consideration for the HG Acquisition and (ii) to pay fees and expenses incurred in connection with the transactions related thereto. On February 3, 2026, Antero Resources borrowed $1.5 billion in a single borrowing to partially fund the HG Acquisition. The Term Loan is scheduled to mature on February 3, 2029. The Term Loan contains the same financial covenant as our Credit Facility requiring Antero Resources to maintain a ratio on a consolidated basis of total indebtedness to capitalization of 65% or less at the end of each fiscal quarter and other affirmative and negative covenants applicable to Antero Resources that are substantially the same as those covenants in our Credit Facility and otherwise customary for term loans of this type, including, among other things, limitations on: fundamental changes such as mergers, consolidations, liquidations and dissolutions; liens; certain indebtedness; restricted payments such as dividends, distributions and equity repurchases; and material non-arms’-length transactions with its affiliates. Antero Resources was in compliance with the financial covenant under the Term Loan as of June 30, 2026. The Term Loan provides for borrowings at Term SOFR or an Alternate Base Rate at our option, in each case, plus the Applicable Rate (each, as defined in the Term Loan). There is a 0.10% credit adjustment spread on SOFR and a 0.00% floor. The Term Loan does not amortize. Interest under the Term Loan is payable at a variable rate based on SOFR or the Alternate Base Rate, determined by election at the time of borrowing and at the end of each applicable interest period in respect of a borrowing, plus the Applicable Rate. The Applicable Rate is determined with reference to Antero Resources’ then-current senior unsecured long-term debt rating, ranging from 1.125% to 2.00% for Term SOFR loans. As of June 30, 2026, Antero Resources had an outstanding balance under the Term Loan of $1.1 billion, with a weighted average interest rate of 5.2%.

If Antero Resources undergoes a change of control followed by a rating decline, the holders of the 2030 Notes will have the right to require Antero Resources to repurchase all or a portion of the notes at a price equal to 101% of the principal amount of the 2030 Notes, plus accrued and unpaid interest. ​
