STEINHAUSEN, Switzerland, Oct. 15, 2025 (GLOBE NEWSWIRE) -- Transocean Ltd. (NYSE:RIG), a Swiss corporation ("Transocean"), announced the early results, as of 5:00 p.m. New York City time on October 14, 2025 (the "Early Tender Date"), of the previously announced cash tender offer (the "Tender Offer") by Transocean International Limited, a Bermuda exempted company limited by shares (the "Company") and a wholly owned subsidiary of Transocean, to purchase up to an aggregate principal amount of the outstanding 7.35% Senior Notes due December 2041 (the "2041 Notes") and 7.00% Notes due June 2028 (the "2028 Notes" and collectively with the 2041 Notes, the "Notes" and each, a "Series") listed in the table below for a combined aggregate purchase price of up to $50,000,000 (excluding accrued and unpaid interest, which also will be paid to, but excluding, the Settlement Date (as defined herein) and excluding fees and expenses related to the Tender Offer), in the order of priority shown in the table below.

The Company also announced that it has amended the terms of the Tender Offer to increase the combined aggregate purchase price from $50,000,000 to $100,000,000 (excluding accrued and unpaid interest, which also will be paid to, but excluding, the Settlement Date and excluding fees and expenses related to the Tender Offer) (as amended, the "Maximum Tender Offer Amount"). All other terms of the previously announced Tender Offer remain unchanged.

As of the Early Tender Date, according to information provided to the Company by D.F. King & Co., Inc., as Tender Agent and Information Agent for the Tender Offer, $88,998,000 aggregate principal amount of the 2041 Notes (approximately 50.21% of the aggregate principal amount outstanding) was validly tendered and $120,628,000 aggregate principal amount of the 2028 Notes (approximately 46.18% of the aggregate principal amount outstanding) was validly tendered. The Company accepted for payment all such 2041 Notes validly tendered and not validly withdrawn in the Tender Offer. The Company will accept for purchase all such 2028 Notes validly tendered and not validly withdrawn at or prior to the Early Tender Date on a pro rata basis based on the proration procedures described in the Offer to Purchase dated September 30, 2025 (the "Offer to Purchase"). As a result, the proration factor applicable to the 2028 Notes is approximately 13.17%. The Total Tender Offer Consideration (as described herein) plus accrued and unpaid interest for the Notes that were validly tendered and not validly withdrawn in the Tender Offer prior to the Early Tender Date and accepted for purchase by the Company will be paid by the Company in same-day funds on October 16, 2025 (the "Settlement Date").

The terms and conditions of the Tender Offer are described in the Offer to Purchase, which was previously distributed to holders of the Notes. All conditions were satisfied or waived by the Company at the Early Tender Date.

(1) The interest rate currently in effect for the 2041 Notes is 9.35%, which is subject to further adjustment from time to time upon a change to the credit rating of the 2041 Notes, but in no event shall the interest rate be reduced below 7.35% or exceed 9.35%.

(2) As of the date of the Offer to Purchase.

(3) Per $1,000 principal amount of Notes validly tendered and accepted for purchase for each Series. Excludes accrued and unpaid interest, which also will be paid to, but excluding, the Settlement Date.  

(4) Per $1,000 principal amount of Notes validly tendered and accepted for purchase for each Series (the "Early Tender Premium").

(5) Per $1,000 principal amount of Notes validly tendered on or before the Early Tender Date, not validly withdrawn and accepted for purchase for each Series. Includes the Early Tender Premium, but excludes accrued and unpaid interest, which will also be paid to, but excluding, the Settlement Date. Holders of Notes that were validly tendered (and not validly withdrawn) prior to the Early Tender Date will receive the Total Tender Offer Consideration.

(6) The 2028 Notes offered for purchase hereby were issued by Global Marine Inc., a Delaware corporation and a wholly owned indirect subsidiary of Transocean.

The Tender Offer will expire at 5:00 p.m., New York City time, on October 29, 2025, unless extended or earlier terminated. However, because the aggregate principal amount of Notes validly tendered and not validly withdrawn at or prior to the Early Tender Date exceeded the Maximum Tender Offer Amount, the Company does not expect to accept for purchase any Notes validly tendered after the Early Tender Date. As a result, the Company expects that any Notes tendered after the Early Tender Date, together with any Notes tendered at or prior to the Early Tender Date but not accepted for purchase in accordance with proration procedures set forth in the Offer to Purchase, will be returned to the holders thereof as described in the Offer to Purchase.

Holders of Notes subject to the Tender Offer who validly tendered their Notes and did not validly withdraw their Notes on or before the Early Tender Date may no longer withdraw their Notes, except in the limited circumstances described in the Offer to Purchase. Holders of Notes subject to the Tender Offer who tender their Notes after the Early Tender Date may not withdraw their Notes except in the limited circumstances described in the Offer to Purchase.

The Company expects to pay the Total Tender Offer Consideration, up to the Maximum Tender Offer Amount, on all Notes validly tendered, not validly withdrawn, and accepted for purchase with proceeds from the New Notes Offering.
