Backlog as of the February 2025 Fleet Status Report	$	8.3 billion

STEINHAUSEN, Switzerland, Feb. 17, 2025 (GLOBE NEWSWIRE) -- Transocean Ltd. (NYSE:RIG) today reported net income attributable to controlling interest of $7 million, or loss of $0.11 per diluted share, for the three months ended December 31, 2024.

Fourth quarter results included $20 million, $0.02 per diluted share, discrete tax items, net. After consideration of these unfavorable items, fourth quarter 2024 adjusted net income was $27 million, or loss of $0.09 per diluted share.

Contract drilling revenues for the three months ended December 31, 2024, increased sequentially by $4 million to $952 million, primarily due to increased utilization for one rig that returned to work after undergoing a special periodic survey in the third quarter and higher reimbursement revenues, partially offset by lower revenue efficiency across the fleet.

Operating and maintenance expense was $579 million, compared with $563 million in the prior quarter. The sequential increase was the result of higher in-service maintenance costs across our fleet, partially offset by a settlement with insurance carriers.

General and administrative expense was $56 million, up from $47 million in the third quarter due primarily to increased legal and professional fees.

Interest expense net of capitalized amounts was $152 million, compared to $154 million in the prior quarter, excluding the favorable adjustment of $61 million and $74 million in the fourth and third quarter, respectively, for the fair value of the bifurcated exchange feature related to the 4.625% exchangeable bonds. Interest income was $10 million, compared to $11 million in the prior quarter.

The Effective Tax Rate⁽²⁾ was 89.0%, up from 6.0% in the prior quarter. The increase was primarily due to higher income and increases in valuation allowance. The Effective Tax Rate excluding discrete items was 56.7% compared to 22.5% in the previous quarter.

Cash provided by operating activities was $206 million during the fourth quarter of 2024, representing an increase of $12 million compared to the prior quarter. The sequential increase was primarily due to timing of interest payments and decreased payments for accounts payable, partially offset by reduced collections from customers.

Fourth quarter 2024 capital expenditures of $29 million, compared to $58 million in the prior quarter, were related to capital upgrades for certain rigs in our fleet.

"In 2024, we continued to advance our position as the technological leader in offshore drilling by, among other things, executing the first two 20K subsea completions in the history of the industry," said Chief Executive Officer Jeremy Thigpen. "We also introduced and implemented other technologies that enhance our operational performances and further differentiate our fleet. This commitment to innovation, along with our reputation for delivering safe, reliable, and efficient operations, is clearly recognized by our customers, as demonstrated by the $2.4 billion in backlog we secured during the year."

Thigpen continued, "With industry-leading contract coverage well into 2026, our primary objective will be strong operational execution and an intense focus on cost control to ensure we maximize the conversion of our backlog to cash, enabling us to continue de-leveraging our balance sheet."

Full Year 2024

For the year ended December 31, 2024, net loss attributable to controlling interest totaled $512 million, $0.76 per diluted share. Full year results included $458 million, $0.50 per diluted share, net unfavorable items as follows:

$755 million, $0.82 per diluted share, loss on impairment of assets; and
$5 million, $0.01 per diluted share, loss on impairment of our investments in unconsolidated affiliates; partially offset by,
$161 million, $0.18 per diluted share, gain on retirement of debt; and
$141 million, $0.15 per diluted share, related to discrete tax items, net.

After consideration of these net unfavorable items, adjusted net loss for 2024 was $54 million, $0.26 per diluted share.

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 Adjusted Contract Drilling Revenues, EBITDA, Adjusted EBITDA and Adjusted Net Income, 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.
