Transocean Ltd. Reports Third Quarter 2026 Results

November 2, 2026

STEINHAUSEN, Switzerland, Nov. 02, 2026 (GLOBE NEWSWIRE) -- Transocean Ltd. (NYSE: RIG) today reported financial results for the third quarter of 2026. The Company will host a conference call and webcast at 9 a.m. EST, 3 p.m. CET, on Tuesday, November 3, 2026, with participation details included in this release. Supplemental schedules have been posted to the Investors section of the Company’s website at www.deepwater.com.

THIRD QUARTER 2026 KEY POINTS

Contract drilling revenues were $937 million with strong revenue efficiency⁽¹⁾ of 96.8%.
Net income was $26 million or $0.02 per diluted share.
Adjusted EBITDA was $313 million, implying a 33.4% margin.
Net cash provided by operating activities was $174 million; net of capital expenditures of $43 million, free cash flow was $131 million.
Ended the period with total liquidity of $1.3 billion, including the existing $510 million undrawn revolving credit facility.
Added $2.0 billion in contract backlog⁽²⁾ at a weighted average dayrate of about $423,000.

“Since our last report, we delivered solid operating results and significantly strengthened forward contract visibility,” said Keelan Adamson, Transocean’s CEO. “Strong cash flow enabled us to retire the remaining $200 million of debt associated with the Deepwater Aquila notes, ahead of schedule. New deepwater and harsh-environment awards increased our backlog to approximately $8.0 billion and improved 2027 contract coverage to approximately 95%.

“Our priorities remain safe and reliable customer service, maximizing conversion of backlog into cash flow, and reducing debt. With all regulatory approvals now in hand and the Valaris closing expected on December 1, we are focused on integration planning and capturing $200 million in identified annual synergies.”

Contract drilling revenues were lower sequentially, primarily due to an expected decrease in rig utilization.

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 difficult to predict. As a result, actual results could differ materially from those indicated in these forward-looking statements. Factors that could cause actual results to differ materially include, but are not limited to, the level of activity in offshore oil and gas exploration and development, exploration success by producers, 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 our expectations regarding the timing, completion and anticipated benefits of the proposed business combination with Valaris Limited, an exempted company limited by shares incorporated under the laws of Bermuda, and those and other risks discussed in the Company's most recent Annual Report on Form 10-K for the year ended December 31, 2025, 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.

NOTES

(1)	Revenue efficiency is defined as actual operating revenues, excluding revenues for contract terminations and reimbursements, for the measurement period divided by the maximum revenue calculated for the measurement period, expressed as a percentage. Maximum revenue is defined as the greatest amount of contract drilling revenues the drilling unit could earn for the measurement period, excluding revenues for incentive provisions, reimbursements and contract terminations. See the accompanying schedule entitled “Revenue Efficiency.”

(2)	Contract backlog is defined as the maximum contractual operating dayrate multiplied by the number of days remaining in the firm contract period, including certain performance-based provisions for which achievement is probable, and excluding provisions for mobilization, demobilization, contract preparation, other incentive provisions or reimbursement revenues, which are not expected to be material to our contract drilling revenues. The contract backlog represents the maximum contract drilling revenues that can be earned considering the reported operating dayrate in effect during the firm contract period.
