Item 7.01Regulation FD Disclosure.

Transocean Ltd. (NYSE: RIG) (“Transocean”) today announced awards of a contract for a harsh environment semisubmersible in Norway and contract extensions for two ultra-deepwater drillships in Brazil. In aggregate, the fixtures represent approximately $1.0 billion in incremental firm contract backlog, as follows.

The Transocean Barents was awarded a 1,095-day contract with Vår Energi ASA in Norway at a rate of $450,000 per day, excluding additional services. The program is anticipated to commence by the middle of the second quarter of 2027 and is expected to contribute approximately $490 million in backlog, excluding compensation for mobilization and demobilization. The contract also includes options that, if fully exercised, could keep the rig working in Norway into 2034.

The Deepwater Orion was awarded a 1,095-day contract extension with Petrobras in direct continuation of its current activity. The extension is expected to contribute approximately $420 million in incremental backlog and commit the rig through March 2030. Prior to the extension period, from April 1, 2026, until the commencement of the new contract extension in March 2027 (approximately 340 days), the existing backlog will be reduced by approximately $20 million.

The Deepwater Aquila was awarded a 365-day contract extension with Petrobras in direct continuation of its current activity. The extension is expected to contribute approximately $160 million in incremental backlog and commit the rig through June 2028. Prior to the extension period, from April 1, 2026, until the commencement of the new contract extension in June 2027 (approximately 450 days), the existing backlog will be reduced by approximately $10 million.

Separately, Transocean retired the 8.375% Senior Secured Notes due 2028 (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 using cash on hand and funds from the associated debt service reserve account. Interest expense savings to maturity is approximately $39 million. The early retirement of the Titan Notes is consistent with the company’s commitment to accelerate deleveraging, reduce interest expense and simplify the balance sheet.  

Including the retirement of the Titan Notes, and excluding any additional early retirements, Transocean currently expects to retire a total of $0.75 billion of debt in 2026.

A copy of the press release announcing the fixtures referred to above is attached hereto and incorporated herein by reference as Exhibit 99.1.
