Entry into a Material Definitive Agreement.

On September 24, 2025, Transocean Ltd. (the “ Company”) entered into an underwriting agreement (the “ Underwriting Agreement”) with Citigroup Global Markets Inc. and Morgan Stanley & Co. LLC, as representatives of the several underwriters named therein (the “ Underwriters”), relating to the previously announced underwritten public offering of 125,000,000 shares, par value $0.10 (the “ Offering”), of the Company.

Under the terms of the Underwriting Agreement, the Company agreed to issue and sell the shares to the Underwriters at a public offering price of $3.05 per share. In addition, the Company granted the Underwriters a 30-day option to purchase up to an additional 18,750,000 of the Company’s shares at the public offering price, less underwriting discounts and commissions, which was exercised in full by the Underwriters on September 25, 2025.

The Underwriting Agreement contains customary representations and warranties, agreements and obligations, closing conditions and termination provisions. The Company has agreed to indemnify the Underwriters against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “ Securities Act”), and to contribute to any payment that the Underwriters may be required to make because of any of those liabilities. The Offering was registered under the Securities Act pursuant to an effective registration statement on Form S-3/ASR (Registration Statement No. 333-280617), as previously filed with and deemed automatically effective by the Securities and Exchange Commission (the “ SEC”), a base prospectus included as part of the registration statement, and a final prospectus supplement filed with the SEC pursuant to Rule 424(b) under the Securities Act.

The Offering is expected to close on September 26, 2025. The Company intends to use the net proceeds from the Offering for the repayment or redemption of indebtedness, including the repayment or redemption of a portion of the $655 million aggregate principal amount of the 8.00% Senior Notes due February 2027 issued by Transocean International Limited, a wholly owned subsidiary of the Company, to the extent such principal is not otherwise refinanced, repaid or redeemed. Any proceeds from the Offering that are not used promptly for such purposes will be used for general corporate purposes.

The foregoing summary of the Underwriting Agreement does not purport to be complete and is qualified in its entirety by reference to the full
