Item 2.06            Material Impairments
​
On June 19, 2024, a subsidiary of Transocean Ltd. (the "Company") entered into an agreement (the "purchase agreement") with a third party pursuant to which the Company agreed to sell the fifth generation ultra-deepwater floater
Deepwater Nautilus
and associated assets for $53.5 million. As part of our ongoing efforts to dispose of non-strategic assets, the Company decided on June 17, 2024, to authorize the sale of the rig and associated equipment, which the Company expects will result in an estimated non-cash charge for the second quarter 2024 ranging between $140 million and $150 million associated with the impairment of such assets. The Company expects to close the transaction contemplated by the purchase agreement in the third quarter of 2024.

Forward-Looking Statements
​
The statements described herein that are not historical facts are forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. These statements could contain words such as "possible," "intend," "will," "if," "expect," or other similar expressions. Forward-looking statements are based on management's current expectations and assumptions, and are subject to inherent uncertainties, risks and changes in circumstances that are beyond our control, and many cases, cannot be predicted. As a result, actual results could differ materially from those indicated by these forward-looking statements. Factors that could cause actual results to differ materially include, but are not limited to, estimated duration of customer contracts, contract dayrate amounts, future contract commencement dates and locations, planned shipyard projects and other out-of-service time, sales of drilling units, the cost and timing of mobilizations and reactivations, operating hazards and delays, risks associated with international operations, actions by customers and other third parties, the fluctuation of current and future prices of oil and gas, the global and regional supply and demand for oil and gas, the intention to scrap certain drilling rigs, the effects of the spread of and mitigation efforts by governments, businesses and individuals related to contagious illnesses, and other factors, including those and other risks discussed in the company's most recent
Annual Report on Form 10-K for the year ended December 31, 2023
, and in the company's other filings with the SEC, which are available free of charge on the SEC's website at: www.sec.gov. Should one or more of these risks or uncertainties materialize, or should underlying assumptions prove incorrect, actual results may vary materially from those indicated. All subsequent written and oral forward-looking statements attributable to us or to persons acting on our behalf are expressly qualified in their entirety by reference to these risks and uncertainties. You should not place undue reliance on forward-looking statements. Each forward-looking statement speaks only as of the date of the particular statement. We expressly disclaim any obligations or undertaking to release publicly any updates or revisions to any forward-looking statement to reflect any change in our expectations or beliefs with regard to the statement or any change in events, conditions or circumstances on which any forward-looking statement is based, except as required by law. All non-GAAP financial measure reconciliations to the most comparative GAAP measure are displayed in quantitative schedules on the company's website at: www.deepwater.com.
