STEINHAUSEN, Switzerland, Oct. 29, 2025 (GLOBE NEWSWIRE) — Transocean Ltd. (NYSE: RIG) today reported a net loss attributable to controlling interest of $1.92 billion, $2.00 per diluted share, for the three months ended September 30, 2025.
Third quarter results included net unfavorable items of $1.985 billion, $2.06 per diluted share, as follows:
$1.908 billion, $1.98 per diluted share, loss on impairment of assets, net of tax;
$75 million, $0.08 per diluted share, loss on conversion of debt to equity; and
$2 million of other unfavorable items, net.
After consideration of these net unfavorable items, third quarter 2025 adjusted net income was $62 million, $0.06 earnings per diluted share.
Contract drilling revenues for the three months ended September 30, 2025, increased sequentially by $40 million to $1.03 billion, primarily due to higher revenues associated with improved rig utilization, improved revenue efficiency, an additional day in the quarter, and an increase in dayrate for one rig, partially offset by lower revenues generated by one rig that was idle between contracts.
Operating and maintenance expense was $584 million, compared to $599 million in the prior quarter. The sequential decrease was primarily due to lower expenses on a rig that completed a special periodic survey during the second quarter.
Interest expense was $140 million, compared with $141 million in the prior quarter, excluding the effect of the bifurcated exchange feature of the 4.625% exchangeable bonds due 2029, which represented an unfavorable adjustment of $14 million and a favorable adjustment of $29 million in the third and second quarter, respectively. Interest income was $12 million, compared to $10 million in the prior quarter.
The Effective Tax Rate(2) was (1.4)%, down from 14.2% in the prior quarter. The decrease was primarily due to losses on rig impairments and changes in the internal ownership of certain rigs. Excluding discrete items, the Effective Tax Rate was 34.8% compared to 70.0% in the previous quarter. In the third quarter, cash paid for taxes was $11 million.
Cash provided by operating activities was $246 million during the third quarter, representing an increase of $118 million compared to the prior quarter. The sequential increase was primarily due to a reduction of working capital.
Third quarter 2025 capital expenditures were $11 million, compared to $24 million in the prior quarter.
“In addition to delivering an outstanding quarter of operational performance and Free Cash Flow generation, we took decisive steps to accelerate debt reduction and improve our financial flexibility,” said President and Chief Executive Officer, Keelan Adamson. “Along with meeting scheduled maturities, these transactions are expected to, respectively, reduce total debt by approximately $1.2 billion by the end of 2025; annual interest expense by approximately $83 million; and restricted cash by $52 million.”
Adamson concluded, “As a result, we have also significantly improved our debt maturity profile over the next several years and believe these actions will further enhance shareholder value.”
Non-GAAP Financial Measures
We present our operating results in accordance with accounting principles generally accepted in the U.S. (“U.S. GAAP”). We believe certain financial measures, such as EBITDA, Adjusted EBITDA, Adjusted Net Income and Free Cash Flow, which are non-GAAP measures, provide users of our financial statements with supplemental information that may be useful in evaluating our operating performance. We believe that such non-GAAP measures, when read in conjunction with our operating results presented under U.S. GAAP, can be used to better assess our performance from period to period and relative to performance of other companies in our industry, without regard to financing methods, historical cost basis or capital structure. Such non-GAAP measures should be considered as a supplement to, and not as a substitute for, financial measures prepared in accordance with U.S. GAAP.
All non-GAAP measure reconciliations to the most comparative U.S. GAAP measures are displayed in quantitative schedules on the company's website at: www.deepwater.com.

(1) Our estimates change as we file tax returns, settle disputes with tax authorities, or become aware of changes in laws, operational changes and rig movements that have an effect on our (a) deferred taxes, (b) valuation allowances on deferred taxes and (c) other tax liabilities.
(2) Our effective tax rate is calculated as income tax expense or benefit divided by income or loss before income taxes.
(3) Our effective tax rate, excluding discrete items, is calculated as income tax expense or benefit, excluding various discrete items (such as changes in estimates and tax on items excluded from income before income taxes), divided by income or loss before income taxes, excluding gains and losses on sales and similar items pursuant to the accounting standards for income taxes related to estimating the annual effective tax rate.
