EXHIBIT 99.1

### TRANSOCEAN LTD. REPORTS first QUARTER 2026 RESULTS
STEINHAUSEN, Switzerland, May 4, 2026—Transocean Ltd. (NYSE: RIG) today reported financial results for the first quarter of 2026. The Company will host a conference call and webcast at 9 a.m. EDT, 3 p.m. CEST, on Tuesday, May 5, 2026, with participation details included in this release. In addition, supplemental schedules have been posted to the Investors section of the Company's website at www.deepwater.com.

#### first quarter 2026 Key points
&nbsp;&nbsp;&nbsp;&nbsp;● Contract drilling revenues were $1.08 billion due in part to strong revenue efficiency <sup>(1)</sup> of 97.3%.

&nbsp;&nbsp;&nbsp;&nbsp;● Net income was $71 million or $0.06 per diluted share.

&nbsp;&nbsp;&nbsp;&nbsp;● Adjusted EBITDA was $440 million, with adjusted EBITDA margin exceeding 40%.

&nbsp;&nbsp;&nbsp;&nbsp;● Net cash provided by operating activities was $164 million; net of capital expenditures of $28 million, Free Cash Flow was $136 million.

&nbsp;&nbsp;&nbsp;&nbsp;● Accelerated retirement of $358 million remaining principal amount of the 8.375% Senior Secured Notes due 2028 (the *Deepwater Titan* Notes), reducing interest to maturity by nearly $40 million.

&nbsp;&nbsp;&nbsp;&nbsp;● Ended the period with total liquidity of $1.125 billion, including the undrawn revolving credit facility.

&nbsp;&nbsp;&nbsp;&nbsp;● Added $1.6 billion in contract backlog <sup>(2)</sup> at a weighted average dayrate of about $410,000.

"The Transocean team delivered exceptional performance to start the year," said Keelan Adamson, President and Chief Executive Officer. "During the quarter, we executed new or extended contracts on five rigs increasing our total backlog to $7.1 billion which, reflecting demand for our differentiated assets, contains an implied average dayrate of over $450,000. We also exceeded our revenue expectations for the quarter and achieved a strong adjusted EBITDA margin above 40%. We continued to enhance our financial flexibility by accelerating debt retirement, reducing interest expense and simplifying our balance sheet.

"Recent global events clearly underscore the importance of secure and reliable hydrocarbon supply. We continue to believe that we are in the early days of a multi-year upcycle with increasing demand for offshore exploration and development drilling services. Transocean is very well-positioned to play a key role in developing these offshore resources and creating long-term shareholder value."

---

&nbsp;&nbsp;&nbsp;&nbsp;● Favorable contract drilling revenues were primarily related to improved rig utilization, higher revenue efficiency and increased average daily revenues across the fleet.

&nbsp;&nbsp;&nbsp;&nbsp;● Interest expense, excluding the $153 million effect of the bifurcated exchange feature of the 4.625% Exchangeable Bonds due 2029, was $123 million.

&nbsp;&nbsp;&nbsp;&nbsp;● Net cash provided by operating activities was $164 million reflecting timing of payments from customers and increased payroll obligations in the period.

&nbsp;&nbsp;&nbsp;&nbsp;● Cash taxes paid in the period were $11 million.

&nbsp;&nbsp;&nbsp;&nbsp;● The Company early retired the *Deepwater Titan* Notes in full on March 20, 2026. The outstanding principal amount of $358 million, plus a call premium and accrued but unpaid interest, was settled with cash on hand and funds from the associated debt service reserve account.

#### Fleet Status Report and contract backlog
&nbsp;&nbsp;&nbsp;&nbsp;● The Company today issued its Fleet Status Report. Since the February 2026 report, we added five new fixtures with an aggregate incremental backlog of approximately $1.6 billion and a weighted average dayrate of about $410,000.

&nbsp;&nbsp;&nbsp;&nbsp;● As of May 4, 2026, the total backlog is approximately $7.1 billion.

#### 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.

#### Notes
&nbsp;&nbsp;&nbsp;&nbsp;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."

&nbsp;&nbsp;&nbsp;&nbsp;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, 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.

&nbsp;&nbsp;&nbsp;&nbsp;3. Effective Tax Rate is defined as income tax expense or benefit divided by income or loss before income taxes. See the accompanying schedule entitled "Supplemental Effective Tax Rate Analysis."

| **Fleet Classifications**. Transocean uses classifications for its drillships and semisubmersibles as follows: "Ultra-Deepwater" are the latest generation of drillships and semisubmersible rigs and are capable of drilling in water depths equal to or greater than 7,500 feet; "Harsh Environment" are premium rigs equipped for year-round operations in harsh environments. |
| **Stacking**. An "Idle" rig is primarily between contracts, readily available for operations, and operating costs are typically at or near normal levels. A "Stacked" rig, on the other hand, is primarily manned by a reduced crew or unmanned and typically has reduced operating costs and is (i) preparing for an extended period of inactivity, (ii) expected to continue to be inactive for an extended period, or (iii) completing a period of extended inactivity. However, stacked rigs will continue to incur operating costs at or above normal operating costs for approximately 30 days following initiation of stacking. |
