Amended and Restated Revolving Loan and Letter of Credit Facility Agreement

On February 14, 2025, we amended and restated our existing credit facility (the "Prior Facility") by entering into the $2,200,000,000 Fourth Amended and Restated Revolving Loan and Letter of Credit Facility Agreement (the "Amended Credit Facility") dated as of February 14, 2025 among us, BNP Paribas, as Administrative Agent, and other lenders party thereto.

The Amended Credit Facility extends the maturity date to February 17, 2028 and increases the size of the facility to $2.2 billion. The Amended Credit Facility contains customary financial and restrictive covenants, including a debt-to-capitalization ratio that cannot exceed 0.60 to 1.00, a limitation on the aggregate amount of debt of the greater of $750 million or €750 million for our subsidiaries, and a minimum liquidity threshold, as defined in the Amended Credit Facility, of $1.175 billion, which may be reduced to $1.00 billion upon the repayment of debt. The minimum liquidity threshold was reduced from $1.25 billion in the Prior Facility. The other restrictive covenants are unchanged from the covenants in the Prior Facility.

The foregoing description of the amendments made to the Prior Facility through the execution of the Amended Credit Facility does not purport to be complete and is qualified in its entirety by reference to the complete text of the Amended Credit Facility, a copy of which will be filed as an exhibit to our Form 10-Q for the quarter ended March 31, 2025.
