The redemptions are currently expected to be consummated on February 16, 2023, assuming the satisfaction by such date of the conditions thereto. This press release does not constitute a notice of redemption under the optional redemption provisions of the indentures governing the Existing Secured Notes.

The timing of pricing and terms of the Notes are subject to market conditions and other factors. All of the net proceeds from the offering will be used to fund the redemption of all of the outstanding Existing Secured Notes, subject to the satisfaction of the conditions precedent thereto. Transocean Inc. will transfer a portion of the net proceeds from the offering, together with cash on hand to the extent required to complete such redemptions, to each applicable subsidiary issuer of the respective series of Existing Secured Notes, and each such issuer will apply such proceeds to consummate such redemption, subject to the satisfaction of the conditions precedent thereto.
