(a) Credit Facility

Antero Resources has a senior revolving credit facility with a consortium of bank lenders. References to the (i) “Secured Credit Facility” (defined below) refer to the credit facility in effect for periods prior to July 30, 2024, (ii) “Unsecured Credit Facility” (defined below) refer to the credit facility in effect on or after July 30, 2024 and (iii) “Credit Facility” refer to the Secured Credit Facility and Unsecured Credit Facility, collectively.

Senior Unsecured Revolving Credit Facility

On July 30, 2024, Antero Resources entered into an amendment and restatement of its senior revolving credit facility with a consortium of bank lenders (“Unsecured Credit Facility”). Borrowings are unsecured and are not guaranteed by any of Antero Resources’ subsidiaries. As of September 30, 2024, the Unsecured Credit Facility had lender commitments of $1.65 billion and available borrowing capacity of $1.0 billion. The Unsecured Credit Facility matures on July 30, 2029 (the “Maturity Date”), provided that Antero Resources may request two one-year extensions of the Maturity Date, subject to satisfaction of certain conditions and consent of the extending lenders. Commitments under the Unsecured Credit Facility may be increased by up to $500 million subject to the agreement of Antero Resources and its lenders.

The Unsecured Credit Facility contains a financial maintenance covenant with respect to Antero Resources’ total indebtedness to capitalization ratio not to exceed 65% at the end of any fiscal quarter, and certain covenants, including restrictions on its ability to incur liens or debt, subject in each case to certain significant exceptions. Antero Resources was in compliance with the financial covenant under the Unsecured Credit Facility as of September 30, 2024.

The Unsecured Credit Facility provides for borrowing at either an Adjusted Term Secured Overnight Financing Rate (“SOFR”), an Adjusted Daily Simple SOFR or an Alternate Base Rate, in each case, plus an Applicable Margin (each as defined in the Unsecured Credit Facility). The Unsecured Credit Facility provides for interest only payments until maturity at which time all outstanding borrowings are due. Interest is payable at a variable rate based on SOFR or the Alternate Base Rate, determined by election at the time of borrowing, plus an Applicable Margin under the Unsecured Credit Facility. The Applicable Margin is determined with reference to Antero Resources’ then-current credit ratings ranging from 1.125% to 2.00% for SOFR loans. Commitment fees on the unused portion of the Unsecured Credit Facility are due quarterly at rates ranging from 0.125% to 0.300% with respect to the Unsecured Credit Facility, determined with reference to Antero Resources’ then-current credit ratings.

The proceeds of the loans made under the Unsecured 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) and (ii) to finance working capital needs, and for other general corporate purposes, of Antero Resources and its subsidiaries.

As of September 30, 2024, Antero Resources had an outstanding balance under the Unsecured Credit Facility of $527 million, with a weighted average interest rate of 6.47%, and outstanding letters of credit of $120 million.

Senior Secured Revolving Credit Facility

On October 26, 2021, Antero Resources entered into an amended and restated senior secured revolving credit facility (the “Credit Facility”) with a consortium of bank lenders (“Secured Credit Facility”). Borrowings were secured by substantially all of the assets of Antero Resources and certain of its subsidiaries, were subject to borrowing base limitations based on the collateral value of Antero Resources’ assets and were subject to regular semi-annual redeterminations. As of December 31, 2023, the Secured Credit Facility had a borrowing base of $3.5 billion with lender commitments of $1.6 billion. The borrowing base was re-affirmed in the semi-annual redetermination in April 2024. The Secured Credit Facility was refinanced in full and terminated upon the closing of the Unsecured Credit Facility on July 30, 2024.

The Secured Credit Facility contained requirements with respect to leverage and current ratios, and certain covenants, including restrictions on our ability to incur debt and limitations on our ability to pay dividends unless certain customary conditions are met, in each case, subject to customary carve-outs and exceptions. Antero Resources was in compliance with all of the financial covenants under the Secured Credit Facility as of December 31, 2023.

The Secured Credit Facility provided for borrowing at either an Adjusted Term SOFR, an Adjusted Daily Simple SOFR or an Alternate Base Rate, in each case, plus an Applicable Margin (each as defined in the Secured Credit Facility). The Secured Credit Facility provided for interest only payments until maturity at which time all outstanding borrowings would be due. Interest was payable at a variable rate based on SOFR or the Alternate Base Rate, determined by election at the time of

borrowing, plus an Applicable Margin under the Secured Credit Facility. The Applicable Margin was determined with reference to Antero Resources’ then-current leverage ratio subject to certain exceptions, which for SOFR loans ranged from 1.75% to 2.75% during a non-investment grade period (based on utilization of the Secured Credit Facility) and 1.25% and 1.875% during an investment grade period (based on a ratings grid). Commitment fees on the unused portion of the Secured Credit Facility were due quarterly at rates ranging from 0.375% to 0.500% with respect to the Secured Credit Facility, determined with reference to borrowing base utilization, subject to certain exceptions based on the leverage ratio then in effect. The Secured Credit Facility included fall away covenants, lower interest rates and reduced collateral requirements that Antero Resources could elect if Antero Resources was assigned an Investment Grade Rating (as defined in the Secured Credit Facility).

As of December 31, 2023, Antero Resources had an outstanding balance under the Secured Credit Facility of $417 million, with a weighted average interest rate of 7.71%, and outstanding letters of credit of $501 million.
