​PROXY STATEMENT SUMMARY

COMPANY OVERVIEW AND 2025 PERFORMANCE

Transocean is a leading international provider of offshore contract drilling services for oil and gas wells. We specialize in technically demanding sectors of the global offshore drilling business with a particular focus on ultra-deepwater and harsh environment drilling services. Our drilling fleet is one of the most versatile fleets in the world, consisting of drillships and semisubmersible floaters.

Transocean’s fleet of 27 mobile offshore drilling units consists of 20 ultra-deepwater floaters and seven harsh environment floaters. The graphic below shows the global market presence of our operating fleet as of our Fleet Status Report issued on February 19, 2026.

With the offshore industry’s largest high-specification floating fleet, and a relentless focus on incident-free operations and superior well construction, we believe that we are best-positioned to support our customers in the delivery of their operational and business objectives, which will ultimately translate into superior returns for our shareholders.

In 2025, we achieved exceptional operational performance. Importantly, we delivered a company-best total recordable incident rate (“TRIR”) of 0.19, below our established objective of 0.20. We also delivered uptime of 97.7% across our global fleet of floaters that are focused on ultra-deepwater and harsh environment operations, which present the most challenging operational conditions.

We believe hydrocarbons will continue to be a critical source of energy for the foreseeable future. Many policy makers are prioritizing energy security, resulting in a diverse and resilient supply portfolio of energy, which we expect will support sustained, long-term demand for oil and natural gas.
