(a) Credit Facility

Antero Midstream Partners, an indirect, wholly owned subsidiary of Antero Midstream Corporation, as borrower (the “Borrower”), has a senior secured revolving credit facility with a consortium of banks, the Credit Facility. On October 26, 2021, the Company entered into an amended and restated senior secured revolving credit facility, the New Credit Facility. As of December 31, 2021, lender commitments under the New Credit Facility were $1.25 billion and matures on October 26, 2026; provided that if on November 17, 2025 any of the 2026 Notes (as defined below) are outstanding, the New Credit Facility will mature on such date.

The Credit Facility contains certain covenants including restrictions on indebtedness, and requirements with respect to leverage and interest coverage ratios. The Credit Facility permits distributions to the holders of the Borrower’s equity interests in accordance with the cash distribution policy, provided that no event of default exists or would be caused thereby, and only to the extent permitted by the Borrower’s organizational documents. The Borrower was in compliance with all of the financial covenants under the Credit Facility as of December 31, 2020 and 2021.

The Prior Credit Facility provides for borrowing under either the Base Rate or the Eurodollar Rate (as each term is defined in the Prior Credit Facility), and the New Credit Facility provides for borrowing under either Adjusted Term Secured Overnight Financing Rate (“SOFR”) or the Base Rate (as each term is defined in the New Credit Facility). Principal amounts borrowed are payable on the maturity date with such borrowings bearing interest that is payable with respect to (i) base rate loans, quarterly and (ii) Eurodollar Rate Loans or SOFR Loans at the end of the applicable interest period if three months (or shorter, if applicable), or every three months if the applicable interest period is longer than three months. Interest is payable at a variable rate based on (i) LIBOR or the base rate, determined by election at the time of borrowing, plus an applicable margin rate under the Prior Credit Facility or (ii) SOFR or the base rate, determined by election at the time of borrowing, plus an applicable margin rate under the New Credit Facility. Interest at the time of borrowing is determined with reference to the Borrower’s then-current leverage ratio subject to certain exceptions. Commitment fees on the unused portion of the Credit Facility are due quarterly at rates ranging from 0.25% to 0.375% subject to certain exceptions based on the leverage ratio then in effect.

As of December 31, 2020, the Borrower had outstanding borrowings under the Prior Credit Facility of $614 million with a weighted average interest rate of 1.66%. As of December 31, 2021, the Borrower had outstanding borrowings under the New Credit Facility of $547 million with a weighted average interest rate of 1.81%. No letters of credit under the Credit Facility were outstanding as of December 31, 2020 and 2021.
