The Additional Notes will have the same terms and conditions as the $1,025,000,000 aggregate principal amount of senior secured notes due 2028, which were issued on November 7, 2023 (the "Original 2028 Notes"). The Additional Notes mature on November 15, 2028. The Additional Notes will be treated as additional notes under the indenture and will be issued bearing the same ISIN and common codes as the Original 2028 Notes, and will be fully fungible and constitute a single series with the Original 2028 Notes.

The proceeds from the offering are intended to be used for general corporate purposes, which may include, among other things, capital expenditures, including delivery costs for newbuild rigs on order, costs in connection with activations of these rigs, optimization of the shipyard newbuild financing currently in place and select asset additions, or funding of our working capital.

Settlement of the notes offering is expected on or about March 12, 2024, and is subject to customary closing conditions.
