ITEM 1. BUSINESS

OVERVIEW

PART I

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,”
the  “Company,”  “we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas
wells.  As of February 14, 2024, we owned or had partial ownership interests in and operated 37 mobile offshore drilling units,
consisting of 28 ultra-deepwater floaters and nine harsh environment floaters.  Additionally, as of February 14, 2024, we were
constructing one ultra-deepwater drillship.

We  provide,  as  our  primary  business,  contract  drilling  services  in  a  single  operating  segment,  which  involves
contracting  our  mobile  offshore  drilling  rigs,  related  equipment  and  work  crews  to  drill  oil  and  gas  wells.   We  specialize  in
technically  demanding  regions  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 used in support of offshore drilling activities and offshore support services on a worldwide basis.

Transocean  Ltd.  is  a  Swiss  corporation  with  its  registered  office  in  Steinhausen,  Canton  of  Zug  and  with  principal
executive  offices  located  at  Turmstrasse  30,  6312  Steinhausen,  Switzerland.    Our  telephone  number  at  that  address  is
+41 41 749-0500.  Our shares are listed on the New York Stock Exchange under the ticker symbol “RIG.”  For information
about the revenues, operating income, assets and other information related to our business and the geographic areas in which we
operate, see “Part  II.  Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations” and
“Part  II.  Item  8.  Financial  Statements  and  Supplementary  Data—Notes  to  Consolidated  Financial  Statements—Note  1—
Business, Note 5—Revenues and Note 7—Long-Lived Assets.”

DRILLING FLEET

Overview—We  provide  contract  drilling  services  using  our  fleet  of  mobile  offshore  drilling  units,  including  both
drillships and semisubmersibles, broadly referred to as floaters.  Floaters are designed to operate in locations away from port for
extended periods of time and have living quarters for the crews, a helicopter landing deck and storage space for drill pipe, riser
and  drilling  supplies.    Our  drilling  units  and  related  equipment  are  suitable  for  both  exploration  and  development,  and  we
engage in both types of activities.

Drillships are floating vessels that are shaped like conventional ships, generally self-propelled and considered to be the
most mobile of the major rig types.  Drillships typically have greater deck load and storage capacity than semisubmersible rigs,
which provides logistical and resupply efficiency benefits for customers.  Drillships are generally better suited to operations in
calmer sea conditions and typically do not operate in areas considered to be harsh environments.  All of our high-specification
drillships  are  equipped  with  dynamic  positioning  thruster  systems,  which  allows  them  to  maintain  position  without  anchors
through the use of onboard propulsion and station-keeping systems.  We have two ultra-deepwater drillships that are equipped
with  an  industry-leading,  1,700  short  ton  hoisting  capacity.    We  have  23  ultra-deepwater  drillships  that  are,  and  one  ultra-
deepwater  drillship  under  construction  that  will  be,  equipped  with  our  patented  dual-activity  technology.    Dual-activity
technology  employs  structures,  equipment  and  techniques  using  two  drilling  stations  within  a  dual  derrick  to  allow  these
drillships  to  perform  simultaneous  drilling  tasks  in  a  parallel,  rather  than  a  sequential  manner,  which  reduces  critical  path
activity and improves efficiency in both exploration and development drilling.

Semisubmersibles are floating vessels that can be partially submerged by means of a water ballast system such that the
lower column sections and pontoons are below the water surface during drilling operations.  Semisubmersibles are known for
stability, making them well suited for operating in rough sea conditions.  Semisubmersible floaters are capable of maintaining
their position over a well either through dynamic positioning or the use of mooring systems.  Although most semisubmersible
rigs are relocated with the assistance of tugs, some units are self-propelled and move between locations under their own power
when afloat on pontoons.  Four of our 12 semisubmersibles are equipped with dual-activity technology and also have mooring
capability.  Two of these four dual-activity units are custom-designed, high-capacity semisubmersible drilling rigs, equipped for
year-round operations in harsh environments, such as those of the Norwegian continental shelf and sub-Arctic waters.

Our fleet consists of ultra-deepwater drillships and semisubmersibles and harsh environment semisubmersibles that are
designed  with  high-specification  capabilities  to  operate  in  the  technically  demanding  regions  of  the  global  offshore  drilling
business.  Ultra-deepwater floaters are equipped with high-pressure mud pumps and are capable of drilling in water depths of
4,500  feet  or  greater.    Harsh  environment  floaters  are  capable  of  drilling  in  harsh  environments  in  water  depths  between
1,500 and 10,000 feet and typically have greater displacement than other semisubmersibles, which offers larger variable load
capacity, more useable deck space and better motion characteristics.

Fleet status—Depending on market conditions, we may idle or stack our non-contracted rigs.  An idle rig is between
drilling  contracts,  readily  available  for  operations,  and  operating  costs  are  typically  at  or  near  normal  operating  levels.    A
stacked  rig  typically  has  reduced  operating  and  maintenance  costs,  is  staffed  by  a  reduced  crew  or  has  no  crew  and  is
(a)  preparing  for  an  extended  period  of  inactivity,  (b)  expected  to  continue  to  be  inactive  for  an  extended  period,  or
(c) completing a period of extended inactivity.  Stacked rigs will continue to incur operating costs at or above normal operating
levels for approximately 30 days following initiation of stacking.  Some idle rigs and all stacked rigs require additional costs to
return to service.  The actual cost to return to service, which in many instances could be significant and could fluctuate over
time, depends upon various factors, including the availability and cost of shipyard facilities, the cost of

- 2 -

Table of Contents

equipment  and  materials,  the  extent  of  repairs,  maintenance  and  commercial  upgrades  that  may  ultimately  be  required,  the
length  of  time  a  rig  has  spent  in  stacking  mode  and  the  time  and  cost  of  assembling  and  training  crew.    We  consider  these
factors, together with market conditions, length of contract, dayrate and other contract terms, when deciding whether to return a
stacked rig to service.  We may not return some stacked rigs to work for drilling services.

Drilling units—The following tables, presented as of February 14, 2024, provide certain specifications for our rigs.
 Unless otherwise noted, the stated location of each rig indicates either the current drilling location, if the rig is operating, or the
next operating location, if the rig is in shipyard with a follow-on contract.  The dates provided represent the expected time of
completion, the year placed into service, and, if applicable, the year of the most recent upgrade.  As of February 14, 2024, we
owned  all  of  the  drilling  rigs  in  our  fleet  noted  in  the  tables  below,  except  for  the  following:  (1)  the  ultra-deepwater  floater
Petrobras  10000,  which  is  subject  to  a  finance  lease  through  August  2029  and  (2)  the  harsh  environment  floater
Transocean Norge, which is owned through our noncontrolling equity ownership interest in Orion Holdings (Cayman) Limited
(together with its subsidiary, “Orion”).

DRILLING CONTRACTS

Our offshore drilling services contracts are individually negotiated and vary in their terms and conditions.  We obtain
most of our drilling contracts through bidding processes in competition against other drilling services contractors and through
direct negotiations with operators.  Drilling contracts generally provide for payment on a dayrate basis, typically with higher
rates  for  periods  when  drilling  operations  are  optimized  and,  conversely,  lower  or  zero  rates  for  periods  during  which  the
drilling unit is not mobilized or when drilling operations are interrupted or restricted, whether due to equipment breakdowns,
adverse  environmental  conditions,  regulatory  approvals  or  otherwise.    A  dayrate  drilling  contract  generally  extends  over  a
period of time either covering the drilling of a single well or group of wells or covering a stated term.  At December 31, 2023,
our  contract  backlog  was  approximately  $9.25  billion,  representing  an  increase  of  11  percent  and  40  percent,  respectively,
compared to the contract backlog at December 31, 2022 and 2021, which was $8.34 billion and $6.60 billion, respectively.  See
“Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations—Performance and
Other Key Indicators.”

Certain of our drilling contracts may be cancelable for the convenience of the customer, typically with payment of an
early termination fee.  Such payments, however, may not fully compensate us for the loss of the contract.  Drilling contracts
also  customarily  provide  for  either  automatic  termination  or  termination  at  the  option  of  the  customer,  typically  without
payment of any termination fee, under various circumstances such as non-performance, in the event of extended downtime or
impaired  performance  due  to  equipment  or  operational  issues  or  extended  downtime  due  to  force  majeure  events.    Many  of
these events are beyond our control.  The contract term in some instances may be extended by the customer exercising options
for the drilling of additional wells or for additional periods of time.  Our contracts also typically include a provision that allows
the customer to extend the contract to finish drilling a well-in-progress.  During periods of depressed market conditions, our
customers may seek to renegotiate drilling contracts or options to reduce the term of their obligations or the average dayrate
through term extensions or may seek to early terminate or repudiate their contracts.  Suspension of drilling contracts will result
in the reduction in or loss of dayrate for the period of the suspension.  If customers cancel some of our contracts and we are
unable to secure new contracts on a timely basis and on substantially similar or more favorable terms, if some of our contracts
are  suspended  for  an  extended  period  of  time  or  if  a  number  of  our  contracts  are  renegotiated  on  less  favorable  terms,  our
consolidated financial position, results of operations or cash flows may be adversely affected.  See “Item 1A. Risk Factors—
Risks  related  to  our  business—Our  drilling  contracts  may  be  terminated  due  to  a  number  of  events,  and,  during  depressed
market conditions, our customers may seek to repudiate or renegotiate their contracts.”

Under dayrate drilling contracts, consistent with standard industry practice, our customers, as the operators, generally
assume, and grant indemnity for, subsurface and well control risks, and their consequential damages.  Under all of our current
drilling  contracts,  our  customers  indemnify  us  for  pollution  damages  in  connection  with  reservoir  fluids  stemming  from
operations under the contract, and we indemnify our customers for pollution that originates above the surface of the water from
the rig for substances in our control, such as diesel used or other fluids stored onboard the rig.  Also, our customers indemnify
us for consequential damages they incur, damage to the well or reservoir, loss of subsurface oil and gas and costs to bring the
well  under  control.    However,  because  our  drilling  contracts  are  individually  negotiated,  the  degree  of  indemnification  we
receive  from  our  customers  for  such  risks  and  related  costs  may  vary  from  contract  to  contract  based  on  market  conditions,
customer  requirements  existing  when  the  contract  was  negotiated  or  other  factors.    In  some  instances,  we  have  contractually
agreed upon certain limits to our indemnification rights and can be responsible for certain damages up to a specified maximum
dollar  amount.    The  nature  of  our  liability  and  the  prevailing  market  conditions,  among  other  factors,  can  influence  such
contractual terms.  Notwithstanding a contractual indemnity from a customer, there can be no assurance that our customers will
be financially able to indemnify us or will otherwise honor their contractual indemnity obligations.

The  interpretation  and  enforceability  of  a  contractual  indemnity  depends  upon  the  specific  facts  and  circumstances
involved, as governed by applicable laws, and may ultimately need to be decided by a court or other proceeding, which would
need  to  consider  the  specific  contract  language,  the  facts  and  applicable  laws.    Applicable  laws  often  consider  contractual
indemnity for criminal fines and penalties to be against public policy.  Many courts also restrict indemnification for criminal
fines  and  penalties.    The  inability  or  other  failure  of  our  customers  to  fulfill  their  indemnification  obligations,  or  the
unenforceability of all of our contractual protections could have a material adverse effect on our consolidated financial position,
results  of  operations  or  cash  flows.    See  “Item  1A.  Risk  Factors—Risks  related  to  our  business—Our  business  involves
numerous  operating  hazards,  and  our  insurance  and  indemnities  from  our  customers  may  not  be  adequate  to  cover  potential
losses from our operations.”

MARKETS

Our operations are geographically dispersed in oil and gas exploration and development areas throughout the world.
 We operate in a single, global offshore drilling market, as our drilling rigs are mobile assets and can be moved according to
prevailing market conditions.  We may mobilize our drilling rigs between regions for a variety of reasons, including to respond
to  customer  contracting  requirements  or  to  capture  observed  market  demand.    Consequently,  we  cannot  predict  the  future
percentage of our revenues that will be derived from particular geographic areas.  As of February 14, 2024, the drilling units in
our  fleet,  including  stacked  and  idle  rigs,  but  excluding  rigs  under  construction,  were  located  in  the  U.S.  Gulf  of  Mexico
(ten  units),  Greece  (seven  units),  Brazil  (five  units),  the  Norwegian  North  Sea  (four  units),  Malaysia  (three  units),  Australia
(two units), Angola (one unit), Aruba (one unit), Canada (one unit), Cyprus (one unit), India (one unit) and the United Kingdom
(the “U.K.”) North Sea (one unit).

We  categorize  the  sectors  of  the  floater  market  in  which  we  operate  as  follows:  (1)  ultra-deepwater  and  deepwater,
(2) harsh environment and (3) midwater.  We typically employ our ultra-deepwater floaters to service the ultra-deepwater and
deepwater  sector,  and  we  employ  our  harsh  environment  floaters  to  service  all  three  sectors.    We  generally  view  the  ultra-
deepwater and deepwater market sector as water depths beginning at 4,500 feet and extending to the maximum water depths in
which rigs are capable of drilling, which is currently up to 12,000 feet.  The midwater market sector includes water depths from
approximately  300  feet  to  approximately  4,500  feet.    The  harsh  environment  market  sector  includes  regions  that  are  more
challenged by lower temperatures, harsher weather conditions and water currents.

The market for offshore drilling rigs and related services reflects  our  customers’  demand  for  equipment  for  drilling
exploration, appraisal and development wells and for performing maintenance on existing production wells.  Activity levels of
energy  companies,  including  integrated  energy  companies,  independent  energy  companies  and,  to  a  lesser  extent,  national
energy companies are largely driven by the worldwide  demand  for  energy,  including  crude  oil  and  natural  gas.    Worldwide
energy  supply  and  demand  drives  oil  and  natural  gas  prices,  which,  in  turn,  impact  energy  companies’  ability  to  fund
investments in exploration, development and production activities.

See  “Part  II.  Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of  Operations—

Outlook.”

CUSTOMERS

We provide our offshore drilling services to most of the leading integrated energy companies or their affiliates, as well
as for many government-owned or government-controlled energy companies and other independent energy companies.  For the
year  ended  December  31,  2023,  our  most  significant  customers  were  Shell  plc  (together  with  its  affiliates,  “Shell”),
Equinor  ASA  (together  with  its  affiliates,  “Equinor”),  TotalEnergies  SE  (together  with  its  affiliates,  “TotalEnergies”)  and
Petróleo Brasileiro S.A. (together with its affiliates, “Petrobras”), representing approximately 27 percent, 16 percent, 12 percent
and 11 percent, respectively, of our consolidated operating revenues.  No other customers accounted for 10 percent or more of
our  consolidated  operating  revenues  in  the  year  ended  December  31,  2023.    Additionally,  as  of  February  14,  2024,  the
customers with the most significant aggregate amount of contract backlog associated with our drilling contracts were Petrobras,
Shell and Chevron Corporation (together with its affiliates, “Chevron”), representing approximately 31 percent, 25 percent and
10 percent, respectively, of our total contract backlog.  See “Item  1A.  Risk  Factors—Risks  related  to  our  business—We  rely
heavily on a relatively small number of customers and the loss of a significant customer or a dispute that leads to the loss of a
customer could have an adverse effect on our business.”

HUMAN CAPITAL RESOURCES

Worldwide workforce—As  of  December  31,  2023,  we  had  a  global  workforce  of  approximately  5,800  individuals,
including  approximately  370  contractors,  representing  53  nationalities.    At  December  31,  2023,  our  global  workforce  was
geographically distributed in 22 countries across six continents as follows: 38 percent in North America, 25 percent in Europe,
23 percent in South America, six percent in Asia, five percent in Africa and three percent in Australia.

FIRST Shared Values and corporate culture—Our FIRST Shared Values serve as the foundation for our corporate
culture and guide us to act ethically and responsibly as we strive to deliver value for our stakeholders and to maintain a safe and
respectful work environment for our people.

Code of Integrity and Human Rights—We maintain a Code of Integrity and Human Rights Policy that applies to all
our board members, executives, employees and business partners, including contractors, suppliers, vendors, investees and joint
venture partners.  We demonstrate our respect of human rights by maintaining a healthy and safe work environment, observing
fair employment practices and providing competitive employment terms.  Practices such as modern slavery, child labor, forced
or indentured servitude, and other human rights abuses are strictly prohibited.

Labor  rights—We  respect  the  labor  rights  of  all  individuals  in  our  workforce,  including  the  right  to  collective
bargaining.   As  of  December  31,  2023,  approximately  42  percent  of  our  total  workforce,  working  primarily  in  Norway  and
Brazil, are represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially
all  of  which  are  subject  to  annual  salary  negotiation.    Negotiations  over  annual  salary  or  other  labor  matters  could  result  in
higher  personnel  or  other  costs  or  increased  operational  restrictions  or  disruptions.    The  outcome  of  any  such  negotiation
generally affects the market for all offshore employees, not only union members.  A failure to reach an agreement on certain key
issues could result in strikes, lockouts or other work stoppages.

innovation, local knowledge and experience required of the world’s premier offshore drilling contractor.  We seek to maintain
our  competitive  advantage  while  benefitting  our  local  communities  by  offering  regionally  competitive  compensation  and
benefits packages, a technically challenging work environment, global opportunities, and rotational development programs.  We
continually assess and adapt our offerings and our policies, based on evolving social and technological practices, to provide a
modern work environment, which is essential to attract and retain top talent, and a respectful and inclusive work environment in
which our global workforce can thrive.  Our focus on the quality of our workforce is designed to maximize the quality of our
work performance and ultimately, the value we deliver to our stakeholders.

Training—We  invest  in  our  workers  by  providing  them  with  the  transferrable  skill  sets  essential  to  advancing  their
professional  development.    To  optimize  the  competitive  position  of  our  business,  we  maintain  a  rigorous  competency-based
training program.  Our internal training board maintains and regularly updates our training matrix to meet or exceed industry
standards,  and  it  oversees  our  competency  assurance  management  system,  which  is  accredited  by  the  Offshore  Petroleum
Industry Training Organization.  We provide various offshore training formats designed to encompass all learning styles through
on-the-job, e-learning, customer-specific training, certifications, and leadership and licensing programs.  Setting us apart from
our competitors, we also offer unique simulation-based education, augmented by digital twin modeling, enabling our workforce
to  more  accurately  visualize  equipment  performance  and  target  efficiencies.    We  clearly  articulate  to  our  workforce  the
certifications,  skills  and  competencies  needed  for  each  role,  and  workers  are  required  to  successfully  complete  the  relevant
training and attain necessary certifications prior to taking on new roles.

Wellness and benefits—We offer our workforce regionally competitive medical and financial benefits, tailored to our
workforce  demographics.   We  design  our  wellness  and  benefits  strategy  under  four  pillars  consisting  of  physical  well-being,
financial well-being, emotional well-being and social well-being, including our globally available employee assistance program.

Safety—Our safety vision is to conduct our operations in an incident-free workplace, all the time, everywhere.  As a
socially responsible company, we prioritize the protection of everyone aboard our rigs and in our facilities, the environment and
our  property  at  all  work  locations  and  during  all  operations.    We  require  compliance  with  all  local  regulations  and  a
comprehensive set of internal requirements that govern our operations.  With regular competency and effectiveness assessments,
our  highly  trained  crews  are  equipped  to  protect  our  operational  integrity  with  the  process-driven  management  of  hazards  to
prevent and mitigate major accidents.  We measure our safety performance in terms of widely accepted ratios with the use of
industry standards, including (a) the total recordable incident rate (“TRIR”), which represents the number of recordable work-
related injuries or illnesses for every 200,000 hours worked, and (b) the lost time incident rate (“LTIR”), which measures the
number of incidents that result in lost time due to work-related injuries or illnesses for every 200,000 hours worked.  In the year
ended December 31, 2023, our TRIR was 0.23 and our LTIR was 0.02, both calculations of which were based on 11.3 million
labor hours.

ENVIRONMENTAL RESPONSIBILITY

We  strive  to  deliver  services  in  a  manner  that  both  minimizes  the  impact  our  business  has  on  the  environment  and
supports the interests of our stakeholders.  We continuously seek new ways to advance our commitment to safely performing
operations  while  simultaneously  safeguarding  the  environment.    We  maintain  a  global  Environmental  Management  System
(“EMS”) standard that is applied to our rigs, offices and facilities.  The EMS is aligned to ISO 14001 and provides a framework
to ensure that our worldwide operations are managed consistently and continuously in an environmentally responsible manner.
 We regularly assess the environmental impact of operations, focusing on the reduction of greenhouse gas emissions, operational
discharges,  water  use  and  waste.    Accordingly,  we  intend  to  reduce  our  greenhouse  gas  operating  emissions  intensity  by
40 percent from 2019 levels by 2030.  Achieving these targets will require investments over time that result in the development
and  implementation  of  new  technologies,  reduced  fuel  consumption  and  other  initiatives  that  enable  us  to  optimize  power
management capabilities.

TECHNOLOGICAL INNOVATION

We have a long history of technological innovation, including the first dynamically positioned drillship, the first rig to
drill year-round in the North Sea, the first semisubmersible rig for year-round sub-Arctic operations, the first 10,000-ft. water
depth  rated  ultra-deepwater  drillship  and  numerous  water  depth  world  records  over  the  past  several  decades.    Twenty-
three drillships and two semisubmersibles in our existing fleet are, and our drillship under construction will be, equipped with
our  patented  dual-activity  technology,  which  allows  our  rigs  to  perform  simultaneous  drilling  tasks  in  a  parallel  rather  than
sequential manner, reducing well construction critical path activities and, thereby, improving efficiency in both exploration and
development drilling.

We  develop  and  deploy  industry-leading  technology  in  the  pursuit  of  delivering  safer,  more  efficient  and
environmentally  responsible  drilling  services.   Two  of  our  drillships  are  equipped  with  1,700  short  ton  hoisting  capacity  and
20,000  psi  blowout  preventers.    Seven  of  our  drillships  and  our  drillship  under  construction  include  hybrid  energy  storage
systems for enhanced drill floor equipment reliability, fuel and emissions savings as well as advanced generator protection for
power plant reliability.  Twelve drillships in our existing fleet are outfitted with dual blowout preventers and triple liquid mud
systems.    Five  drillships  in  our  existing  fleet  are  designed  to  accept  20,000  psi  blowout  preventers  in  the  future.    We  also
continue  to  develop  and  invest  in  technologies  designed  to  optimize  our  performance,  deliver  ever  improving  operational
integrity and reduce our greenhouse gas emissions.

Table of Contents

Seven of our harsh environment semisubmersibles are designed and constructed specifically to provide highly efficient
performance in harsh environments.  We have installed automated drilling control systems on six harsh environment floaters,
which materially improves our ability to safely and efficiently deliver wells to our customers.

We  utilize  technology  and  employ  a  data-driven  approach,  augmented  by  the  size  of  our  fleet,  to  expand  our
knowledge framework for sustainable process optimization.  In 2020, we deployed our smart equipment analytics tool, which
delivers real-time data feeds from equipment to monitor equipment health, inferred emissions and energy consumption while
identifying  performance  trends  that  allow  us  to  systematically  optimize  equipment  maintenance  and  achieve  higher  levels  of
reliability, operational efficiency and sustainability.

Driven  by  our  continued  focus  on  safety,  we  developed  and,  on  eight  of  our  drilling  units,  deployed  our  patented
HaloGuard℠  system,  which  alarms,  notifies  and,  if  required,  halts  equipment  to  avoid  injury  to  personnel  who  move  into
danger  zones.    In  2022,  we  deployed  the  first  unit  of  Enhanced  Drilling’s  EC-Monitor  system  to  an  offshore  installation,
enabling highly accurate understanding of well fluid dynamics and improving the efficiency and accuracy of flow-checking and
detecting  flow  anomalies.    Additionally,  since  2021,  we  deployed  on  two  of  our  ultra-deepwater  drillships  the  first  kinetic
blowout stopper, a step-changing technology that promotes operations integrity and enterprise risk reduction through unrivaled
shearing capability.  Since 2022, we deployed an offshore robotic riser bolting tool on three of our ultra-deepwater drillships,
improving our ability to deliver safe and efficient operations to our customers.

We  believe  our  efforts  to  continuously  improve,  and  effectively  use,  innovative  technologies  to  meet  or  exceed  our
customers’  requirements  is  critical  to  maintaining  our  competitive  position  within  the  contract  drilling  services  industry  by
ensuring the safety of our crews, drilling more efficient wells, building greater resilience into our critical operating systems and
reducing fuel consumption and emissions.

JOINT VENTURE, AGENCY AND SPONSORSHIP RELATIONSHIPS AND OTHER INVESTMENTS

In some areas of the world, local customs and practice or governmental requirements necessitate the formation of joint
ventures  with  local  participation  since  local  laws  or  customs  in  those  areas  effectively  mandate  the  establishment  of  a
relationship  with  a  local  agent  or  sponsor.    When  appropriate  in  these  areas,  we  may  enter  into  agency  or  sponsorship
agreements.    We  also  invest  in  certain  companies  for  operational  and  strategic  purposes.    Some  of  these  companies  or  joint
ventures in which we are an investor are involved in researching and developing technology to improve efficiency, reliability,
sustainability and safety for our drilling and other activities or are involved in businesses developed to support renewable or
other energy alternatives.  We may or may not control these partially owned companies.  At December 31, 2023, we held partial
ownership interests in companies organized in Belgium, the Cayman Islands, the U.S., Norway, Canada and other countries.  At
December  31,  2023,  among  other  equity  investments,  we  held  noncontrolling  equity  ownership  interests  in  (1)  Global  Sea
Mineral Resources NV, an unconsolidated Belgian company and leading developer of nodule collection technology, which is
engaged  in  the  development  and  exploration  of  deep-sea  polymetallic  nodules  that  contain  metals  critical  to  the  growing
renewable  energy  market,  and  (2)  Orion,  an  unconsolidated  Cayman  Islands  exempted  company  that  owns  the  harsh
environment semisubmersible Transocean Norge.

GOVERNMENTAL REGULATIONS

Our  operations  are  subject  to  a  variety  of  international,  national,  regional,  state  and  local  government  regulations,
including  environmental  regulations.    We  monitor  our  compliance  with  such  government  regulations  in  each  country  of
operation and, notwithstanding increases in governmental regulations, particularly general environmental regulations, we have
made and will continue to make the required expenditures to comply with current and future government requirements.  To date,
we have not incurred material costs to comply with such governmental regulations, and we do not expect to make any material
capital  expenditures  to  support  our  continued  compliance  in  the  year  ending  December  31,  2024,  or  any  other  period
contemplated at this time.  We do not believe that our compliance with such requirements will have a material adverse effect on
our competitive position, consolidated results of operations or cash flows.  We incorporate by reference herein the disclosures

ITEM 1A.RISK FACTORS

RISKS RELATED TO OUR BUSINESS

OUR  BUSINESS  DEPENDS  ON  THE  LEVEL  OF  ACTIVITY  IN  THE  OFFSHORE  OIL  AND  GAS  INDUSTRY,
WHICH IS SIGNIFICANTLY AFFECTED BY VOLATILE OIL AND GAS PRICES AND OTHER FACTORS.

Our business depends on oil and gas exploration, development and production in offshore areas where we are capable
of operating.  Demand for our services depends on these activities and related expenditure levels that are directly affected by
trends in oil and, to a lesser extent, natural gas prices.  Oil and gas prices are extremely volatile and are affected by numerous
factors, including the following:

◾ worldwide  demand  for  oil  and  gas,  including  economic  activity  in  the  U.S.,  other  large  energy-consuming  markets  and  in

developing and emerging markets;

◾ the  ability  of  the  Organization  of  the  Petroleum  Exporting  Countries  (“OPEC”)  to  set  and  maintain  production  levels,

productive spare capacity and pricing among its members;

◾ the level of production in non-OPEC countries;
◾ inventory levels, and the cost and availability of storage and transportation of oil, gas and their related products;
◾ the policies, laws and regulations of various governments regarding exploration and development of their oil and gas reserves
and environmental matters, including those addressing alternative energy sources and the risks of global climate change;

◾ international sanctions on oil-producing countries, or the lifting of such sanctions;
◾ advances in exploration, development and production technology;
◾ the development, exploitation and market acceptance of alternative energy sources;
◾ the further development of shale technology to exploit oil and gas reserves;
◾ the discovery rate of new oil and gas reserves and the rate of decline of existing oil and gas reserves;
◾ accidents, adverse weather conditions, natural disasters and other similar incidents relating to the oil and gas industry; and
◾ the worldwide security and political environment, including uncertainty or instability resulting from an escalation or outbreak

of armed hostilities, civil unrest, acts of terrorism, public health threats or other crises.

Demand for our services is particularly sensitive to the level of exploration, development and production activity of,
and the corresponding capital spending by, energy companies, including national energy companies.  Prolonged reductions in oil
and natural gas prices could depress the immediate levels of exploration, development and production activity.  Perceptions of
longer-term  lower  oil  and  natural  gas  prices  by  energy  companies,  or  a  perception  that  the  demand  for  hydrocarbons  will
significantly  decrease  in  the  medium  to  long  term,  could  similarly  reduce  or  defer  major  expenditures  given  the  long-term
nature  of  many  large-scale  development  projects  and  capital  reinvestment  policies.    Lower  levels  of  activity  result  in  a
corresponding  decline  in  the  demand  for  our  services,  which  could  have  a  material  adverse  effect  on  our  revenue  and
profitability.  Oil and gas prices and market expectations of potential changes in these prices significantly affect this level of
activity.  However, increases in near-term commodity prices do not necessarily translate into increased offshore drilling activity
since  customers’  expectations  of  longer-term  future  commodity  prices  and  expectations  regarding  future  demand  for
hydrocarbons typically have a greater impact on demand for our rigs.  Consistent with this dynamic, customers may delay or
cancel many exploration and development programs, resulting in reduced demand for our services.  Also, increased competition
for customers’ drilling budgets could come from, among other areas, land-based energy markets and renewable energy projects
worldwide.  The availability of quality drilling prospects, exploration success, relative production costs, the stage of reservoir
development and political and regulatory environments also affect customers’ drilling campaigns.  Worldwide military, political
and economic events have often contributed to oil and gas price volatility and are likely to do so in the future.

THE OFFSHORE DRILLING INDUSTRY IS HIGHLY COMPETITIVE AND CYCLICAL, WITH INTENSE PRICE
COMPETITION.

The offshore contract drilling industry is highly competitive with numerous industry participants, none of which has a
dominant  market  share.    Drilling  contracts  are  traditionally  awarded  on  a  competitive  bid  basis.    Although  rig  availability,
service quality and technical capability are drivers of customer contract awards, bid pricing and intense price competition are
often key determinants for which a qualified contractor is awarded a job.

The  offshore  drilling  industry  is  highly  cyclical  and  is  impacted  by  oil  and  natural  gas  price  levels  and  volatility.
  Periods  of  high  customer  demand,  limited  rig  supply  and  high  dayrates  have  been  followed  by  periods  of  low  customer
demand,  excess  rig  supply  and  low  dayrates.    Changes  in  commodity  prices  can  have  a  dramatic  effect  on  rig  demand,  and
periods of excess rig supply may intensify competition in the industry and result in the idling of older and less technologically
advanced equipment.  We have idled and stacked rigs, and may in the future idle or stack additional rigs or enter into lower
dayrate drilling contracts in response to market conditions.  Idled or stacked rigs may remain out of service for extended periods
of  time.    During  prior  periods  of  high  dayrates  and  rig  utilization  rates,  we  and  other  industry  participants  responded  to
increased customer demand by increasing the supply of rigs through ordering the construction of new units.  The introduction of
new units delivered without contracts, combined with an increased number of rigs in the global market completing contracts and
becoming idle, may intensify price competition.  During periods of low oil and natural gas price levels, new construction has
resulted  in  an  oversupply  of  rigs  and  has  caused  a  subsequent  decline  in  dayrates  and  rig  utilization  rates,  sometimes  for
extended periods of time.  In

an  oversupplied  market,  we  may  have  limited  bargaining  power  to  negotiate  on  more  favorable  terms.   Additionally,  lower
market dayrates and intense price competition may drive customers to seek to renegotiate existing contracts to reduce dayrates
in  exchange  for  longer  contract  terms.    Lower  dayrates  and  rig  utilization  rates  could  adversely  affect  our  revenues  and
profitability.

As  of  February  14,  2024,  we  have  13  uncontracted  rigs,  of  which  six  have  been  out  of  service  for  greater  than
five years, and these rigs may remain out of service for extended periods of time.  If we are unable to obtain drilling contracts
for our uncontracted rigs, whether due to a prolonged offshore drilling market downturn, a delayed or muted recovery of such
market or otherwise, it may have an adverse effect on our results of operations and cash flows.

WE  MAY  NOT  BE  ABLE  TO  RENEW  OR  OBTAIN  NEW  DRILLING  CONTRACTS  FOR  RIGS  WHOSE
CONTRACTS ARE EXPIRING OR OBTAIN DRILLING CONTRACTS FOR OUR STACKED AND IDLE RIGS.

The offshore drilling markets in which we compete experience fluctuations in the demand for drilling services.  Our
ability  to  renew  expiring  drilling  contracts  or  obtain  new  drilling  contracts  depends  on  the  prevailing  or  expected  market
conditions.  As of February 14, 2024, we have 13 stacked or idle rigs.  We also have three existing drilling contracts for our rigs
that  are  currently  operating,  which  are  scheduled  to  expire  before  December  31,  2024.   We  may  be  unable  to  obtain  drilling
contracts for our rigs that are currently operating upon the expiration or termination of such contracts, and there may be a gap in
the operation of the rigs between the current contracts and subsequent contracts.  When oil and natural gas prices are low or it is
expected that such prices will decrease in the future, we may be unable to obtain drilling contracts at attractive dayrates or at all.
 We may not be able to obtain new drilling contracts with the terms or dayrates sufficient to support a reactivation of a cold-
stacked  rig.    Likewise,  we  may  not  be  able  to  obtain  new  drilling  contracts  in  direct  continuation  with  existing  contracts,  or
depending  on  prevailing  market  conditions,  we  may  enter  into  drilling  contracts  at  dayrates  substantially  below  the  existing
dayrates or on terms otherwise less favorable compared to existing contract terms, which may have an adverse effect on our
financial position, results of operations or cash flows.

OUR CURRENT BACKLOG OF CONTRACT DRILLING REVENUES MAY NOT BE FULLY REALIZED.

At February 14, 2024, our contract backlog was approximately $9.01 billion.  This amount represents the maximum
contractual operating dayrate multiplied by the number of days remaining in the firm contract period, excluding revenues for
mobilization,  demobilization,  contract  preparation,  other  incentive  provisions  or  reimbursement  revenues,  which  are  not
expected  to  be  significant  to  our  contract  drilling  revenues.    Our  contract  backlog  includes  amounts  associated  with  our
one  contracted  newbuild  unit  that  is  currently  under  construction.   The  contractual  operating  dayrate  may  be  higher  than  the
actual dayrate we ultimately receive or an alternative contractual dayrate, such as waiting on weather rate, repair rate, standby
rate or force majeure rate, may apply under certain circumstances.  The contractual operating dayrate may also be higher than
the  actual  dayrate  we  ultimately  receive  due  to  a  number  of  factors,  including  rig  downtime  or  suspension  of  operations.
  Several  factors  could  cause  rig  downtime  or  a  suspension  of  operations,  including:  equipment  breakdowns  and  other
unforeseen engineering problems, labor strikes and other work stoppages, shortages of material and skilled labor, surveys by
government and maritime authorities, periodic classification surveys, severe weather or harsh operating conditions, and force
majeure events.

In certain drilling contracts, the dayrate may be reduced to zero if, for example, repairs extend beyond a stated period
of time.  Our contract backlog includes only firm commitments, which are represented by signed drilling contracts or, in some
cases, other definitive agreements awaiting contract execution.  We may not be able to realize the full amount of our contract
backlog  due  to  events  beyond  our  control.    In  addition,  some  of  our  customers  have  experienced  liquidity  issues  in  the  past,
including  some  recently,  and  these  liquidity  issues  could  be  experienced  again  if  commodity  prices  decline  for  an  extended
period of time.  Liquidity issues and other market pressures could lead our customers to seek bankruptcy protection or to seek to
repudiate, cancel or renegotiate these agreements for various reasons (see “—Our drilling contracts may be terminated due to a
number  of  events,  and,  during  depressed  market  conditions,  our  customers  may  seek  to  repudiate  or  renegotiate  their
contracts”).    Our  inability  to  realize  the  full  amount  of  our  contract  backlog  may  have  an  adverse  effect  on  our  financial
position, results of operations or cash flows.

WE  MUST  MAKE  SUBSTANTIAL  CAPITAL  AND  OPERATING  EXPENDITURES  TO  REACTIVATE  OUR
STACKED  OR  IDLE  FLEET  AND  TO  MAINTAIN  OUR  ACTIVE  FLEET,  AND  WE  MAY  BE  REQUIRED  TO
MAKE SIGNIFICANT CAPITAL EXPENDITURES TO MAINTAIN OUR COMPETITIVENESS AND TO COMPLY
WITH  LAWS  AND  APPLICABLE  REGULATIONS  AND  STANDARDS  OF  GOVERNMENTAL  AUTHORITIES
AND ORGANIZATIONS.

We must make substantial capital and operating expenditures to maintain our active fleet or to reactivate our stacked or
idle  fleet.    These  expenditures  could  increase  as  a  result  of  changes  in  the  cost  of  labor  and  materials,  requirements  of
customers, the size of our fleet, the cost of replacement parts for existing rigs, the geographic location of the rigs and the length
of  drilling  contracts.    Changes  in  offshore  drilling  technology,  customer  requirements  for  new  or  upgraded  equipment  and
competition  within  our  industry  may  require  us  to  make  significant  capital  expenditures  in  order  to  maintain  our
competitiveness  and  to  achieve  our  intention  to  reduce  our  greenhouse  gas  emission  intensity.    Changes  in  governmental
regulations, including environmental requirements, and changes in safety or other equipment standards, as well as compliance
with standards imposed by maritime self-regulatory organizations, may cause our capital expenditures to increase or require us
to  make  additional  unforeseen  capital  expenditures.   As  a  result  of  these  factors,  we  may  be  required  to  take  our  rigs  out  of
service for extended periods of time, with corresponding losses of revenues, in order to make such alterations or to add such
equipment.  In the future, market conditions may not justify these expenditures or enable us to operate our older rigs profitably
during the remainder of their economic lives.

Table of Contents

If  we  are  unable  to  fund  capital  expenditures  with  our  cash  flows  from  operations  or  proceeds  from  sales  of  non-
strategic  assets,  we  may  be  required  to  either  incur  additional  borrowings  or  raise  capital  through  the  sale  of  debt  or  equity
securities, or additional financing arrangements with banks or other capital providers.  Our ability to access the capital markets
may be limited by our financial condition at the time, perceptions of us or our industry, by changes in laws and regulations or
interpretation thereof and by adverse market conditions resulting from, among other things, general economic conditions and
contingencies and uncertainties that are beyond our control.  If we raise funds by issuing equity securities or other securities that
are  convertible  into  equity  securities,  existing  shareholders  may  experience  dilution.    Our  failure  to  obtain  the  funds  for
necessary future capital expenditures could have a material adverse effect on our business and on our financial position, results
of operations and cash flows.

OUR OPERATING AND MAINTENANCE COSTS WILL NOT NECESSARILY FLUCTUATE IN PROPORTION TO
CHANGES IN OUR OPERATING REVENUES.

Our operating and maintenance costs will not necessarily fluctuate in proportion to changes in our operating revenues
and  are  affected  by  many  factors,  including  inflation.    Costs  for  operating  a  rig  are  generally  fixed  or  only  semi-variable
regardless of the dayrate being earned.  To the extent a drilling contract provides for escalations attributable to inflation in our
costs,  those  adjustments  will  lag  the  impact  of  inflationary  pressures  and  may  not  reflect  the  full  impact  to  us  of  any  cost
inflation.   As  drilling  contracts  with  such  provisions  expire  or  are  terminated,  there  can  be  no  assurance  that  future  drilling
contracts will contain similar provisions, which may reduce our margins in inflationary environments.  In addition, should our
rigs incur unplanned downtime while on contract or idle time between drilling contracts, we will not always reduce the staff on
those rigs because we could use the crew to prepare the rig for its next contract.  During times of reduced activity, reductions in
costs may not be immediate because portions of the crew may be required to prepare rigs for stacking, after which time the crew
members may be reassigned to active rigs or released.  As our rigs are mobilized from one geographic location to another, the
labor and other operating and maintenance costs can vary significantly.  In general, labor costs increase primarily due to higher
salary levels and inflation.  Equipment maintenance costs fluctuate depending upon the type of activity the unit is performing
and the age and condition of the equipment, and these costs could increase for short or extended periods as a result of regulatory
or  customer  requirements  that  raise  maintenance  standards  above  historical  levels.    The  amount  of  contract  preparation  and
reactivation costs vary based on the scope and length of the contract preparation or reactivation project, and the recognition of
such costs varies depending on the duration of the firm contractual period and other contract terms.

Certain of our drilling contracts are partially payable in local currency.  The amounts, if any, of local currency received
under these drilling contracts may exceed our local currency needs to pay local operating and maintenance costs, leading to an
accumulation  of  excess  local  currency  balances,  which,  in  certain  instances,  may  be  subject  to  either  restrictions  or  other
difficulties  in  converting  to  U.S.  dollars,  our  functional  currency,  or  to  other  currencies  of  the  locations  where  we  operate.
 Excess amounts of local currency may also be exposed to the risk of currency exchange losses.

CHANGING  SENTIMENT  TOWARDS  CLIMATE  CHANGE,  FOSSIL  FUELS  AND  OTHER  ESG  MATTERS
COULD  ADVERSELY  AFFECT  OUR  BUSINESS,  COST  OF  CAPITAL  AND  THE  PRICE  OF  OUR  STOCK  AND
OTHER SECURITIES.

Changing  sentiment  among  the  public,  regulators  and  non-governmental  organizations  concerning  fossil  fuels  has
prompted  efforts  aimed  in  part  at  the  investment  community,  including  investment  advisors,  sovereign  wealth  funds,  public
pension funds, universities and other groups, to discourage initial investments in and promote the divestment of shares of energy
companies, as well as to pressure lenders and other financial services companies to limit or curtail activities with certain energy
companies.    If  such  efforts  are  successful,  the  market  price  of  our  shares  and  our  ability  to  access  capital  markets  may  be
negatively impacted.

Members  of  the  investment  community  are  also  increasing  their  focus  on  environmental,  social  and  governance
(“ESG”)  practices  and  disclosures,  including  those  related  to  greenhouse  gas  emissions  and  climate  change,  in  the  energy
industry in particular, and diversity and inclusion among public companies more generally.  We may be subject in the future to
additional  reporting  requirements  that  are  developing  in  response  to  such  increased  focus  and,  as  a  result,  we  may  face
increasing pressure regarding our ESG disclosures and practices.

Additionally,  members  of  the  investment  community  may  screen  companies  such  as  ours  for  ESG  sustainability
performance before investing in our stock.  As a result, there has been a proliferation of ESG focused investment funds seeking
ESG oriented investment products.  If we or our securities are unable to meet the sustainability ESG standards or investment
criteria set by these investors and funds, we may lose investors or investors may allocate a portion of their capital away from us.
 As a result, our cost of capital may increase, the market price of our shares or of our publicly traded debt securities may be
negatively impacted and our reputation may also be negatively affected.

PUBLIC  HEALTH  THREATS  HAVE  HAD,  AND  MAY  CONTINUE  TO  HAVE,  SIGNIFICANT  ADVERSE
CONSEQUENCES FOR GENERAL ECONOMIC, FINANCIAL AND BUSINESS CONDITIONS, AS WELL AS FOR
OUR BUSINESS AND OPERATIONS.

Public  health  threats,  including  pandemics  and  epidemics,  severe  influenza,  coronaviruses  and  other  highly
communicable viruses or diseases, have impacted and may continue to impact our operations directly or indirectly, including by
disrupting the operations of our business partners, suppliers and customers in ways that adversely impact our operations.  Such
impacts may include, among others:

◾ causing a temporary shut-down of operations in case of an outbreak on one or more of our rigs;

- 10 -

Table of Contents

◾ disrupting or restricting the ability of our suppliers, manufacturers and service providers to supply parts, equipment labor or

services in the jurisdictions in which we operate or conduct shipyard activities including newbuild construction;

◾ causing us to incur increased costs, inefficiencies, and labor shortages as a result of precautionary measures taken to counteract

a potential or actual outbreak, including testing and quarantining of offshore personnel; and

◾ being negatively affected by various actions by governmental authorities around the world designed to prevent or reduce the
spread  of  an  outbreak,  such  as  imposing  mandatory  closures  of  all  business  facilities  deemed  to  be  non-essential,  seeking
voluntary  closures  of  such  facilities  and  imposing  restrictions  on,  or  issuing  advisories  with  respect  to,  travel,  business
operations and public gatherings or interactions.

As a result, we may experience significant adverse consequences in our ability to meet our commitments to customers,
including  due  to  increased  operating  costs  and  increased  risk  of  rig  downtime  or  contract  termination,  which  may  result  in
substantial  adverse  consequences  for  our  business  and  results  of  operations.    In  addition,  public  health  threats  may  result  in
significantly reduced global or regional economic activity, which could result in a sharp reduction in the demand for oil and an
associated decline in oil prices, as occurred during 2020.  Such conditions may result in, reductions to our customers’ drilling
and production expenditures and delays or cancellations of projects, which may cause a decrease in demand for our services and
an increase in the risk that our customers may seek to terminate or renegotiate pricing or other terms for our existing contracts
or that more of our rigs may become idle, stacked or retired from our fleet.

The  magnitude  and  duration  of  potential  social,  economic  and  labor  instability  resulting  from  such  public  health
threats,  including  the  speed  at  which  national  economies  can  recover,  or  whether  any  recovery  will  ultimately  experience  a
reversal or other setbacks, are uncertain and cannot be estimated as such effects depend on future events that would be largely
out of our control.

WE  RELY  HEAVILY  ON  A  RELATIVELY  SMALL  NUMBER  OF  CUSTOMERS  AND  THE  LOSS  OF  A
SIGNIFICANT CUSTOMER OR A DISPUTE THAT LEADS TO THE LOSS OF A CUSTOMER COULD HAVE AN
ADVERSE EFFECT ON OUR BUSINESS.

We engage in offshore drilling services for most of the leading integrated energy companies or their affiliates, as well
as for many government-owned or government-controlled energy companies and other independent energy companies.  For the
year ended December 31, 2023, our most significant customers were Shell, Equinor, TotalEnergies and Petrobras, representing
approximately 27 percent, 16 percent, 12 percent and 11 percent, respectively, of our consolidated operating revenues.  As of
February 14, 2024, the customers with the most significant aggregate amount of contract backlog associated with our drilling
contracts were Petrobras, Shell and Chevron, representing approximately 31 percent, 25 percent and 10 percent, respectively, of
our total contract backlog.  The loss of any of these customers or another significant customer, or a decline in payments under
any of our drilling contracts, could, at least in the short term, have an adverse effect on our business.

OUR BUSINESS INVOLVES NUMEROUS OPERATING HAZARDS, AND OUR INSURANCE AND INDEMNITIES
FROM  OUR  CUSTOMERS  MAY  NOT  BE  ADEQUATE  TO  COVER  POTENTIAL  LOSSES  FROM  OUR
OPERATIONS.

Our operations are subject to the usual hazards inherent in the drilling of oil and gas wells, such as, blowouts, reservoir
damage, loss of production, loss of well control, lost or stuck drill strings, equipment defects, craterings, fires, explosions and
pollution.  Contract drilling requires the use of heavy equipment and exposure to hazardous conditions, which may subject us to
liability  claims  by  employees,  customers  and  other  parties.    These  hazards  can  cause  personal  injury  or  loss  of  life,  severe
damage  to  or  destruction  of  property  and  equipment,  pollution  or  environmental  or  natural  resource  damage,  claims  by  third
parties or customers and suspension of operations.  Our offshore fleet is also subject to hazards inherent in marine operations,
either while on site or during mobilization, such as capsizing, sinking, grounding, collision, piracy, damage from severe weather
and marine life infestations.

The  U.S.  Gulf  of  Mexico,  the  South  China  Sea  and  the  Northwest  Coast  of  Australia  are  areas  subject  to  typhoons,
hurricanes  or  other  extreme  weather  conditions  on  a  relatively  frequent  basis,  and  our  drilling  rigs  in  these  regions  may  be
exposed to damage or total loss by these storms, some of which may not be covered by insurance.  The occurrence of these
events could result in the suspension of drilling operations, damage to or destruction of the equipment involved and injury to or
death of rig personnel.  Some experts believe global climate change could increase the frequency and severity of these extreme
weather conditions.  Operations may also be suspended because of machinery breakdowns, abnormal drilling conditions, failure
of subcontractors to perform or supply goods or services, or personnel shortages.  We customarily provide contract indemnity to
our customers for certain claims that could be asserted by us relating to damage to or loss of our equipment, including rigs, and
claims that could be asserted by us or our employees relating to personal injury or loss of life.

Damage to the environment or natural resources could also result from our operations, particularly through spillage of
hydrocarbons, fuel, lubricants or other chemicals and substances used in drilling operations, or extensive uncontrolled fires.  We
may also be subject to property damage, environmental indemnity and other claims by energy companies or other third parties.
 Drilling involves certain risks associated with the loss of control of a well, such as blowout, cratering, the cost to regain control
of  or  redrill  the  well  and  remediation  of  associated  pollution.    Our  customers  may  be  unable  or  unwilling  to  indemnify  us
against such risks.  In addition, a court may decide that certain indemnities in our current or future drilling contracts are not
enforceable.  The law generally considers contractual indemnity for criminal fines and penalties to be against public policy, and
the enforceability of an indemnity as to other matters may be limited.

Our insurance policies and drilling contracts contain rights to indemnity that may not adequately cover our losses, and
we do not have insurance coverage or rights to indemnity for all risks.  We have two main types of insurance coverage: (1) hull
and machinery coverage for physical damage to our property and equipment and (2) excess liability coverage, which generally
covers  offshore  risks,  such  as  personal  injury,  third-party  property  claims,  and  third-party  non-crew  claims,  including  wreck
removal and pollution.  We generally have no hull and machinery insurance coverage for damages caused by named storms in
the U.S. Gulf of Mexico.  We maintain per occurrence deductibles

- 11 -

Table of Contents

that  generally  range  up  to  $10  million  for  various  third-party  liabilities,  and  we  self-insure  $50  million  of  the  $750  million
excess liability coverage through our wholly owned captive insurance company.  We also retain the risk for any liability that
exceeds our excess liability coverage.  However, pollution and environmental risks generally are not completely insurable.

If  a  significant  accident  or  other  event  occurs  that  is  not  fully  covered  by  our  insurance  or  by  an  enforceable  or
recoverable  indemnity,  the  occurrence  could  adversely  affect  our  financial  position,  results  of  operations  or  cash  flows.   The
amount of our insurance may also be less than the related impact on enterprise value after a loss.  Our insurance coverage will
not in all situations provide sufficient funds to protect us from all liabilities that could result from our drilling operations.  Our
coverage  includes  annual  aggregate  policy  limits.   As  a  result,  we  generally  retain  the  risk  for  any  losses  in  excess  of  these
limits.    We  generally  do  not  carry  insurance  for  loss  of  revenue,  and  certain  other  claims  may  also  not  be  reimbursed  by
insurance carriers.  Any such lack of reimbursement may cause us to incur substantial costs.  In addition, we could decide to
retain  more  risk  in  the  future,  resulting  in  higher  risk  of  losses,  which  could  be  material.    Moreover,  we  may  not  be  able  to
maintain  adequate  insurance  in  the  future  at  rates  that  we  consider  reasonable  or  be  able  to  obtain  insurance  against  certain
risks.

OUR  DRILLING  CONTRACTS  MAY  BE  TERMINATED  DUE  TO  A  NUMBER  OF  EVENTS,  AND,  DURING
DEPRESSED  MARKET  CONDITIONS,  OUR  CUSTOMERS  MAY  SEEK  TO  REPUDIATE  OR  RENEGOTIATE
THEIR CONTRACTS.

Certain of our drilling contracts with customers may be cancelable at the option of the customer upon payment of an
early  termination  payment.    Such  payments  may  not,  however,  fully  compensate  us  for  the  loss  of  the  contract.    In  the
third quarter of 2023, as the most recent example, Development Driller III concluded the activities contemplated in its drilling
contract  prior  to  the  end  of  the  contract’s  firm  term  that  was  previously  expected  early  in  the  fourth  quarter  of  2023.    The
termination  payment  associated  with  the  drilling  contract  would  not  fully  compensate  us  for  the  early  termination  of  the
contract.    Drilling  contracts  also  customarily  provide  for  either  automatic  termination  or  termination  at  the  option  of  the
customer,  typically  without  the  payment  of  any  termination  fee,  under  various  circumstances  such  as  non-performance,  as  a
result  of  significant  downtime  or  impaired  performance  caused  by  equipment  or  operational  issues,  or  sustained  periods  of
downtime due to force majeure events, many of which are beyond our control.  Certain customers who seek to terminate our
drilling  contracts  may  attempt  to  defeat  or  circumvent  our  protections  against  certain  liabilities.    Our  customers’  ability  to
perform their obligations under their drilling contracts, including their ability to fulfill their indemnity obligations to us, may
also be negatively impacted by an economic downturn.  Our customers, which include national energy companies, often have
significant  bargaining  leverage  over  us.    If  our  customers  cancel  some  of  our  contracts,  and  we  are  unable  to  secure  new
contracts on a timely basis and on substantially similar terms, or if contracts are suspended for an extended period of time or if a
number  of  our  contracts  are  renegotiated  on  terms  that  are  not  as  favorable  as  current  terms,  it  could  adversely  affect  our
financial position, results of operations or cash flows.

During periods of depressed market conditions, such as we have recently experienced, we are subject to an increased
counterparty risk, as our customers may seek to repudiate their contracts, including through claims of non-performance in order
to reduce their capital expenditures.  Our customers may no longer need a drilling rig that is currently under contract or may be
able to obtain a comparable drilling rig at a lower dayrate.  We have experienced, and are at continued risk of experiencing,
early contract terminations when there is a weak commodity price environment.  The ability of each of our counterparties to
perform its obligations under a contract with us, including indemnity obligations, will depend on a number of factors that are
beyond our control and may include, among other things, general economic conditions, the condition of the offshore drilling
industry, prevailing prices for oil and natural gas, the overall financial condition of the counterparty, the dayrates received and
the level of expenditures necessary to maintain drilling activities.  Should a counterparty fail to honor its obligations under an
agreement with us, we could sustain losses, which could have an adverse effect on our business and on our financial position,
results of operations or cash flows.

FAILURE TO RECRUIT AND RETAIN PERSONNEL COULD HURT OUR OPERATIONS.

We depend on the continuing efforts of key members of our management, as well as other highly skilled personnel, to
operate  and  provide  technical  services  and  support  for  our  business  worldwide.    Historically,  competition  for  the  personnel
required for drilling operations has intensified as the number of rigs activated, added to worldwide fleets or under construction
increased,  leading  to  shortages  of  qualified  personnel  in  the  industry  and  creating  upward  pressure  on  wages  and  higher
turnover.  We may experience a reduction in the experience level of our personnel as a result of any increased turnover, which
could  lead  to  higher  downtime  and  more  operating  incidents,  which  in  turn  could  decrease  revenues  and  increase  costs.    If
increased competition for qualified personnel were to intensify in the future we may experience increases in costs or limits on
operations.

OUR  LABOR  COSTS  AND  THE  OPERATING  RESTRICTIONS  UNDER  WHICH  WE  OPERATE  COULD
INCREASE  AS  A  RESULT  OF  COLLECTIVE  BARGAINING  NEGOTIATIONS  AND  ADDITIONAL
UNIONIZATION EFFORTS.

As of December 31, 2023, approximately 42 percent of our total workforce, working primarily in Norway and Brazil,
are represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially all of
which  are  subject  to  annual  salary  negotiation.    Negotiations  over  annual  salary  or  other  labor  matters  could  result  in  higher
personnel  or  other  costs  or  increased  operational  restrictions  or  disruptions.   The  outcome  of  any  such  negotiation  generally
affects  the  market  for  all  offshore  employees,  not  only  the  union  members.   A  failure  to  reach  an  agreement  on  certain  key
issues  could  result  in  strikes,  lockouts,  or  other  work  stoppages.    Legislation  has  been  introduced  in  the  U.S.  Congress  that
could encourage additional unionization efforts in the U.S., as well as increase the chances that such efforts succeed.  Additional
unionization efforts, if successful, new collective bargaining agreements or work stoppages could materially increase our labor
costs and operating restrictions.

OUR SHIPYARD PROJECTS AND OPERATIONS ARE SUBJECT TO DELAYS AND COST OVERRUNS.

We have a variety of shipyard projects underway, at any given time, for our existing rigs at any given time, and as of
February  14,  2024,  we  were  constructing  one  ultra-deepwater  drillship.    These  shipyard  projects  are  subject  to  the  risks  of
delays or cost overruns inherent in any such complex projects resulting from numerous factors, including the following:

◾ shipyard availability, failures and difficulties;
◾ shortages of equipment, materials or skilled labor;
◾ failure  or  delayed  deliveries  of  significant  materials  or  equipment  for  various  reasons,  including  due  to  supplier  shortages,

constraints, disruption or quality issues;

◾ design and engineering problems, including those relating to the commissioning of newly designed equipment;
◾ latent damages or deterioration to hull, equipment and machinery in excess of engineering estimates and assumptions;
◾ unanticipated actual or purported change orders;
◾ disputes with shipyards and suppliers;
◾ availability of suppliers to recertify equipment for enhanced regulations;
◾ strikes, labor disputes and work stoppages;
◾ customer acceptance delays or delays in providing customer-supplied engineering, approvals or equipment;
◾ adverse weather conditions, including damage caused by such conditions;
◾ terrorist acts, war, piracy and civil unrest;
◾ complications  arising  from  pandemics  and  epidemics,  such  severe  influenza,  coronaviruses  and  other  highly  communicable
viruses  or  diseases,  and  associated  government  orders  in  the  country  where  the  rigs  are  being  constructed  or  serviced  and
elsewhere;

◾ unanticipated cost increases; and
◾ difficulties in obtaining necessary permits or approvals or in completing necessary importation procedures.

These factors may contribute to cost variations and delays in the delivery of rigs undergoing shipyard projects or any
future newbuild units.  Cost variations may result in, among other things, disputes with the shipyards that construct or service
our drilling units.  In addition, delayed delivery of our newbuild units or other rigs undergoing shipyard projects would impact
contract commencement, resulting in a loss of revenues we could earn, and may also cause customers to terminate or shorten
the term of the drilling contract for the rig pursuant to applicable late delivery clauses.  In the event of termination of any of
these drilling contracts, we may not be able to secure a replacement contract on as favorable terms, if at all.

Our operations rely on a significant supply of capital and consumable spare parts and equipment to maintain and repair
our  fleet.    We  also  rely  on  the  supply  of  ancillary  services,  including  supply  boats  and  helicopters.    Our  reliance  on  our
suppliers, manufacturers and service providers to secure equipment, parts, components and sub-systems used in our operations
exposes  us  to  volatility  in  the  quality,  prices  and  availability  of  such  items.    Certain  parts  and  equipment  that  we  use  in  our
operations may be available only from a small number of suppliers, manufacturers or service providers, or in some cases must
be sourced through a single supplier, manufacturer or service provider.  Some parts and equipment require long lead times to
obtain, and an unplanned failure or other need to replace any such parts and equipment may result in a longer than usual time to
obtain  them  or  require  us  to  pay  higher  costs  to  obtain  them  on  an  expedited  basis.   A  disruption  in  the  deliveries  from  our
suppliers,  manufacturers  or  service  providers,  capacity  constraints,  production  disruptions,  price  increases,  quality  control
issues, recalls or other decreased availability of parts and equipment or ancillary services could adversely affect our ability to
meet our commitments to customers, adversely impact our operations, increase our operating costs and result in increases in rig
downtime and delays in the repair and maintenance of our fleet.

AS  PART  OF  OUR  BUSINESS  STRATEGIES,  WE  MAY  PURSUE  OPPORTUNITIES  TO  STRENGTHEN  AND
BROADEN OUR BUSINESS THAT INCLUDE ACQUISITIONS OF BUSINESSES OR DRILLING RIGS, MERGERS
OR JOINT VENTURES OR OTHER INVESTMENTS, AND SUCH TRANSACTIONS WOULD PRESENT VARIOUS
RISKS AND UNCERTAINTIES.

We  may  pursue  transactions  that  involve  the  acquisition  of  businesses  or  assets,  mergers  or  joint  ventures  or  other
investments  that  we  believe  will  enable  us  to  further  strengthen  or  broaden  our  business.    Any  such  transaction  would  be
evaluated  on  a  case-by-case  basis,  and  the  consummation  thereof  would  be  dependent  upon  several  factors,  including
identifying  suitable  companies,  businesses  or  assets  that  align  with  our  business  strategies,  reaching  agreement  with  the
potential counterparties on acceptable terms, the receipt of any applicable regulatory and other approvals, and other conditions.
 These transactions involve various risks, including among others, (i) difficulties related to integrating or managing applicable
parts  of  an  acquired  business  or  joint  venture  and  unanticipated  changes  in  customer  and  other  third-party  relationships
subsequent  to  closing,  (ii)  diversion  of  management's  attention  from  day-to-day  operations,  (iii)  failure  to  realize  anticipated
benefits, such as cost savings, revenue enhancements or strengthening or broadening our business, (iv) potentially substantial
transaction costs associated with acquisitions, joint ventures or investments if we or a transaction counterparty seeks to exit or
terminate an interest in the joint venture or investment, and (v) potential accounting impairment or actual diminution or loss of
value of our investment if future market, business or other conditions ultimately differ from our assumptions at the time of such
transaction is consummated.

FAILURE  TO  EFFECTIVELY  AND  TIMELY  ADDRESS  THE  TRANSITION  TO  RENEWABLE  OR  OTHER
ALTERNATIVE ENERGY SOURCES, OR TO RESPOND TO OTHER CLIMATE RELATED BUSINESS TRENDS,
COULD ADVERSELY AFFECT OUR BUSINESS, RESULTS OF OPERATIONS AND CASH FLOWS.

Our  long-term  success  will  be  impacted  by  our  ability  to  effectively  address  the  transition  to  renewable  and  other
alternative energy sources, and our ability to respond to other climate-related business trends that could adversely impact the
long-term demand for oil and

- 13 -

Table of Contents

natural  gas  and,  ultimately,  the  demand  for  our  services  and  products  from  our  services.   Addressing  increased  focus  on  the
development  of  additional  alternative  energy  sources  and  other  climate-related  business  trends  has  required  and  will  further
require adapting certain parts of our operations to changing government requirements and customer preferences.

We continue to engage with existing and potential customers and suppliers to develop or implement solutions designed
to reduce or decarbonize oil and gas operations, or to advance renewable and other alternative energy sources.  Nonetheless, as
it is not possible at this time to predict the timing, scope and effect of the development of and transition to renewable or other
alternative  energy  sources,  any  such  developments,  such  as  the  declining  cost  of  renewable  energy  generation  technologies,
could adversely impact the long-term global demand for oil and natural gas and, ultimately, the demand for our services and
products  from  our  services.    If  the  transition  to  alternative  energy  sources  or  other  climate-related  trends  change  faster  than
anticipated  or  develop  in  a  manner  that  we  do  not  anticipate,  our  business,  results  of  operations  and  cash  flows  could  be
adversely affected.  If we do not or are perceived to not effectively implement a strategy that incorporates alternative energy
sources, or if investors or financial institutions shift funding away from companies in fossil fuel-related industries, our access to
capital or the market for our securities could be negatively impacted.

OUR ASPIRATIONS, GOALS, COMMITMENT TARGETS AND INITIATIVES RELATED TO SUSTAINABILITY,
INCLUDING  EMISSIONS  REDUCTION,  AND  OUR  PUBLIC  STATEMENTS  AND  DISCLOSURES  REGARDING
THEM, EXPOSE US TO NUMEROUS RISKS.

We have developed, and will continue to develop and set, goals, targets, and other objectives related to sustainability
matters, including our commitment target to reduce greenhouse gas emissions operating intensity.  Statements related to these
goals,  commitment  targets  and  objectives  reflect  our  current  intentions  and  do  not  constitute  a  guarantee  that  they  will  be
achieved.  Our efforts to research, establish, accomplish, and accurately report on these goals, commitment targets, and other
objectives expose us to numerous operational, reputational, financial, legal, and other risks.  Our ability to achieve any stated
goal, commitment target, or objective, including with respect to emissions intensity reduction, is subject to numerous factors
and conditions, many of which are outside of our control.

Our business may face increased scrutiny from investors and other stakeholders related to our sustainability activities,
including  the  goals,  commitment  targets,  and  other  objectives  that  we  announce,  and  our  methodologies  and  timelines  for
pursuing  them.    If  our  sustainability  assumptions  or  practices  do  not  meet  investor  or  other  stakeholder  expectations  and
standards,  which  continue  to  evolve,  our  reputation,  our  ability  to  attract  or  retain  employees,  and  our  attractiveness  as  an
investment or business partner could be negatively affected.  Similarly, our failure or perceived failure to pursue or fulfill our
sustainability-focused goals, targets, and objectives, to comply with ethical, environmental, or other standards, regulations, or
expectations, or to satisfy various reporting standards with respect to these matters, within the timelines we announce, or at all,
could adversely affect our business or reputation, as well as expose us to government enforcement actions and private litigation.

RISKS RELATED TO OUR INDEBTEDNESS

WE  HAVE  A  SUBSTANTIAL  AMOUNT  OF  DEBT,  INCLUDING  SECURED  DEBT,  AND  WE  MAY  LOSE  THE
ABILITY TO OBTAIN FUTURE FINANCING AND SUFFER COMPETITIVE DISADVANTAGES.

At December 31, 2023, our total debt was $7.41 billion, of which $2.34 billion was secured.  We have a bank credit
agreement  (as  amended,  the  “Secured  Credit  Facility”),  which  is  currently  undrawn,  the  borrowings  under  which  would  be
secured and guaranteed by certain of our subsidiaries.  This substantial level of debt and other obligations could have significant
adverse consequences on our business and future prospects, including the following:

◾ we may be unable to obtain financing in the future to refinance our existing debt or for working capital, capital expenditures,

acquisitions, debt service requirements, distributions, share repurchases, or other purposes;

◾ we may be unable to use operating cash flows in other areas of our business because we must dedicate a substantial portion of

these funds to service the debt;

◾ we could become more vulnerable to general adverse economic and industry conditions, including increases in interest rates,

particularly given our substantial indebtedness, some of which bears interest at variable rates;

◾ we may be unable to meet financial ratios in the agreements governing certain of our debt facilities and finance lease or satisfy
certain  other  covenants  and  conditions  included  in  our  debt  agreements,  which  could  result  in  our  inability  to  meet
requirements for borrowings under the Secured Credit Facility or a default under such agreements, impose restrictions with
respect to our access to certain of our capital, and trigger cross default provisions in our other debt instruments;

◾ if  we  default  under  the  terms  of  our  secured  financing  arrangements,  the  secured  debtholders  may,  among  other  things,

foreclose on the collateral securing the debt, including the applicable drilling units;

◾ we  may  be  unable  to  obtain  new  investment  or  financing  given  recent  ESG-influenced  trends  among  many  financial
intermediaries, investors and other capital markets participants in reducing, or ceasing, lending to, or investing in, companies
that operate in industries with higher perceived environmental exposure; and

◾ we  may  be  less  able  to  take  advantage  of  significant  business  opportunities  and  to  react  to  changes  in  market  or  industry

conditions than our less levered competitors.

CREDIT  RATING  AGENCIES  HAVE  RATED  OUR  DEBT  BELOW  INVESTMENT  GRADE,  WHICH  COULD
LIMIT OUR ACCESS TO CAPITAL AND HAVE AN ADVERSE EFFECT ON OUR BUSINESS AND FINANCIAL
CONDITION.

The ratings assigned to our debt securities by certain credit rating agencies (our “Debt Ratings”) are below investment
grade.  Our Debt Ratings could have adverse consequences for our business and future prospects and could cause the following:

◾ limitations on our ability to access debt markets, including for the purpose of refinancing our existing debt and replacing or

extending our Secured Credit Facility;

◾ less favorable terms and conditions on any refinancing arrangements, debt issuances or bank credit agreements, some of which

could require collateral and restrict, among other things, our ability to pay distributions or repurchase shares;

◾ increases  to  certain  fees  under  our  Secured  Credit  Facility  and  interest  rates  under  the  indentures  governing  certain  of  our

senior notes;

◾ reduced willingness of current and prospective customers, suppliers and creditors to transact business with us;
◾ requirements from creditors, suppliers or customers for additional insurance, guarantees and collateral;
◾ limitations on our access to bank and third-party guarantees, surety bonds and letters of credit; and
◾ reductions to or eliminations of the level of credit suppliers and financial institutions may provide through payment terms or
intraday funding when dealing with us thereby increasing the need for higher levels of cash on hand, which would decrease
our ability to repay debt balances.

Our Debt Ratings have caused some of the effects listed above, and any further downgrades may cause or exacerbate,

any of the effects listed above and could have an adverse effect on our business and financial condition.

WORLDWIDE  FINANCIAL,  ECONOMIC  AND  POLITICAL  CONDITIONS  COULD  RESTRICT  OUR  ABILITY
TO ACCESS THE CAPITAL MARKETS, REDUCE OUR FLEXIBILITY TO REACT TO CHANGING ECONOMIC
AND BUSINESS CONDITIONS AND REDUCE DEMAND FOR OUR SERVICES.

Worldwide financial and economic conditions could restrict our ability to access the capital markets at a time when we
would like, or need, to access such markets, which could have an impact on our flexibility to react to changing economic and
business  conditions.   Worldwide  economic  conditions  have  in  the  past  impacted,  and  could  in  the  future  impact,  the  lenders
participating  in  our  credit  facilities  and  our  customers,  causing  them  to  fail  to  meet  their  obligations  to  us.    If  economic
conditions  preclude  or  limit  financing  from  banking  institutions  participating  in  our  credit  facilities,  we  may  not  be  able  to
obtain similar financing from other institutions.  A slowdown in economic activity could reduce worldwide demand for energy
and reverse or worsen the recovery from low oil and natural gas prices.  These potential developments, or market perceptions
concerning  these  and  related  issues,  could  adversely  affect  our  financial  position,  results  of  operations  or  cash  flows.    In
addition,  turmoil  and  hostilities  in  the  Middle  East,  Eastern  Europe,  North  Africa  and  other  geographic  areas  and  countries
present  incremental  risk.    An  extended  period  of  negative  outlook  for  the  world  economy  could  further  reduce  the  overall
demand for oil and natural gas and for our services.  A further decline in oil and natural gas prices or an extension of the current
low oil and natural gas prices could reduce demand for our drilling services and have an adverse effect on our financial position,
results of operations or cash flows.

RISKS RELATED TO LAWS, REGULATIONS AND GOVERNMENTAL COMPLIANCE

IMPACT OF INCREASINGLY STRINGENT ENVIRONMENTAL AND SAFETY LAWS AND OUR COMPLIANCE
WITH OR BREACH OF SUCH LAWS CAN BE COSTLY, EXPOSE US TO LIABILITY AND COULD LIMIT OUR
OPERATIONS.

Our  business  is  affected  by  laws  and  regulations  relating  to  the  energy  industry  and  the  environment  and  safety,
including international conventions and treaties, and regional, national, state, and local laws and regulations.  Our business also
depends  on  demand  for  services  from  the  oil  and  gas  exploration  and  production  industry,  and,  accordingly,  we  are  directly
affected  by  the  adoption  of  laws  and  regulations  that,  for  economic,  environmental  or  other  policy  reasons,  curtail,  delay  or
impose  additional  compliance  costs  and  obligations  related  to  the  exploration  and  development  drilling  for  oil  and  gas.
  Offshore  drilling  in  certain  areas  has  been  curtailed  and,  in  certain  cases,  prohibited  because  of  environmental  or  safety
concerns.    In  addition,  compliance  with  environmental  and  safety  laws,  regulations  and  standards,  where  applicable,  may
require us to make significant capital expenditures, such as the installation of costly equipment or implementation of operational
changes, and may affect the resale values or useful lives of our rigs.  We may also incur additional costs in order to comply with
other  existing  and  future  regulatory  obligations  or  industry  standards,  including,  but  not  limited  to,  costs  relating  to  air
emissions,  including  greenhouse  gases,  the  management  of  ballast  waters,  maintenance  and  inspection,  development  and
implementation of emergency procedures and maintenance of insurance coverage or other financial assurance of our ability to
address pollution incidents.  In the last decade, enhanced governmental safety and environmental requirements applicable to our
operations  were  adopted  by  U.S.  federal  agencies  for  drilling  in  the  U.S.  Gulf  of  Mexico.    These  requirements  have  caused
increased compliance costs and may in the future increase the risk of environmental or safety enforcement cases and litigation
and cause operators to have difficulties obtaining drilling permits in the U.S. Gulf of Mexico.  The Bureau of Ocean Energy
Management  (the  “BOEM”)  has  also  proposed  changes  regarding  when  oil,  gas  and  sulfur  lessees  and  certain  other  parties
operating in the offshore Outer Continental Shelf must post additional bonds or other supplemental financial assurance, which
could, if finalized, increase bonding requirements for some of our customers.

The  oil  and  gas  industry  has  adopted  equipment  and  operating  standards,  such  as  the  American  Petroleum  Institute
Standard  53,  related  to  the  installation  and  testing  of  well  control  equipment.   A  failure  to  comply  with  applicable  laws  and
regulations  may  result  in  administrative  and  civil  penalties,  criminal  sanctions  or  the  suspension  or  termination  of  our
operations.   Additionally,  our  customers  may  elect  to  voluntarily  comply  with  any  non-mandatory  laws,  regulations  or  other
standards.    Any  such  safety,  environmental  and  other  regulatory  restrictions  or  standards,  including  voluntary  customer
compliance  with  respect  thereto,  could  decrease,  disrupt  or  delay  operations,  decrease  demand  for  offshore  drilling  services,
increase operating costs and compliance costs or penalties, increase out-of-service time,

- 15 -

Table of Contents

decrease dayrates, or reduce the area of operations for drilling rigs in the U.S. and non-U.S. offshore areas.  Any such effects
could have an adverse effect on our financial position, results of operations or cash flows.

To the extent new laws are enacted, existing laws are changed or other governmental actions are taken that prohibit or
restrict offshore drilling or impose additional environmental protection and safety requirements that result in increased costs to
the oil and gas industry, in general, or the offshore drilling industry, in particular, our business or prospects could be materially
and  adversely  affected.    The  operation  of  our  drilling  rigs  will  require  certain  governmental  approvals,  some  of  which  may
involve public hearings and costly undertakings on our part.  We may not obtain such approvals or such approvals may not be
obtained in a timely manner.  If we fail to timely secure the necessary governmental approvals or permits, our customers may
have the right to terminate or seek to renegotiate their drilling contracts to our detriment.  The amendment or modification of
existing  laws  and  regulations  or  the  adoption  of  new  laws  and  regulations  curtailing  or  further  regulating  exploratory  or
development  drilling  or  production  of  oil  and  gas  and  compliance  with  any  such  new  or  amended  legislation  or  regulations
could have an adverse effect on our business or on our financial position, results of operations or cash flows.

As  a  contract  driller  with  operations  in  certain  offshore  areas,  we  may  be  liable  for  damages  and  costs  incurred  in
connection with oil spills or disposal of wastes related to those operations, and we may also be subject to significant fines and
other liabilities in connection with spills.  For example, an oil spill could result in significant liability, including fines, penalties
and criminal liability and remediation, restoration or compensation costs for environmental or natural resource damages, as well
as third-party damages, to the extent that the contractual indemnification provisions in our drilling contracts are not enforceable
or  otherwise  sufficient,  or  if  our  customers  are  unwilling  or  unable  to  contractually  indemnify  us  against  these  risks.
 Additionally, we may not be able to obtain such indemnities in our future drilling contracts, and our customers may not have
the financial capability to fulfill their contractual obligations to us.  Also, these indemnities may be held to be unenforceable in
certain  jurisdictions,  as  a  result  of  public  policy  or  for  other  reasons.    See  “—Our  business  involves  numerous  operating
hazards,  and  our  insurance  and  indemnities  from  our  customers  may  not  be  adequate  to  cover  potential  losses  from  our
operations.”

Environmental  and  safety  laws  and  regulations  protecting  the  environment  have  become  increasingly  stringent  and
may in some cases impose strict liability on facility or vessel owners or operators, rendering a person liable for environmental
damage without regard to negligence.  These laws and regulations may expose us to liability for the conduct of, or conditions
caused by, others or for acts that were in compliance with all applicable laws at the time they were performed.  The application
of these requirements or the adoption of new requirements or measures could have an adverse effect on our financial position,
results of operations or cash flows.

REGULATORY AND VARIOUS OTHER RISKS, INCLUDING LITIGATION, ASSOCIATED WITH GREENHOUSE
GAS  EMISSIONS,  OTHER  EMISSIONS  AND  CLIMATE  CHANGE  COULD  HAVE  AN  ADVERSE  IMPACT  ON
OUR BUSINESS AND DEMAND FOR OUR SERVICES.

Scientific studies have suggested that emissions of certain gases, including greenhouse gases, such as carbon dioxide
and methane, contribute to warming of the earth’s atmosphere and other climatic changes.  In response to such studies, the issue
of climate change and the effect of greenhouse gas emissions, in particular emissions from the fossil fuel industry, has attracted
and continues to attract considerable political and social attention worldwide.  The attention to climate change has led, and we
expect  it  to  continue  to  lead,  to  additional  regulations  designed  to  reduce  greenhouse  gas  emissions  domestically  and
internationally.  In August 2022, for example, the U.S. enacted the Inflation Reduction Act of 2022, which contains hundreds of
billions  of  dollars  in  incentives  for  the  development  of  renewable  energy,  clean  hydrogen,  clean  fuels,  electric  vehicles  and
supporting infrastructure and carbon capture and sequestration, amongst other provisions.  Additionally, at the United Nations
Climate Change Conference in the United Arab Emirates in December 2023, more than 190 governments reached a non-binding
agreement to transition away from fossil fuels and encourage the growth and expansion of renewable energy.  Such attention
could  also  result  in  other  adverse  impacts  for  the  oil  and  gas  industry,  including  further  restrictions  or  bans  imposed  by
lawmakers, lawsuits by governments or third-parties seeking recoveries for damages resulting from the combustion of fuels that
may  contribute  to  climate  change  effects,  decreased  demand  for  goods  and  services  that  produce  significant  greenhouse  gas
emissions, or reduced interest from investors if they elect in the future to shift some or all of their investments to non-fossil fuel
related sectors.  To the extent financial markets view climate change and greenhouse emissions as a financial risk, this could
negatively  impact  our  cost  of  or  access  to  capital.    Because  our  business  depends  on  the  level  of  activity  in  the  oil  and  gas
industry,  existing  or  future  laws,  regulations,  treaties  or  international  agreements  related  to  greenhouse  gases  and  climate
change,  or  related  political,  litigation  or  financial  risks,  including  incentives  to  conserve  energy  or  use  alternative  energy
sources, could have a negative impact on our business if such laws, regulations, treaties or international agreements reduce the
worldwide demand for oil and gas or limit drilling opportunities.  In addition, such laws, regulations, treaties or international
agreements or related risks could result in increased compliance costs or additional operating restrictions, which may have an
adverse effect on our business.  Further, some experts believe global climate change could increase the frequency and severity
of extreme weather conditions, the impacts of which could interfere with our operations, cause damage to our equipment as well
as cause other financial and operational impacts, including those that could result from any impact of such conditions on our
customers.

We could also face increased climate-related litigation with respect to our operations both in the U.S. and around the
world.  Governmental and other entities in various U.S. states, such as California and New York, have filed lawsuits against
coal, gas oil and petroleum companies.  These suits allege damages as a result of climate change, and the plaintiffs are seeking
unspecified damages and abatement under various tort theories.  Similar lawsuits may be filed in other jurisdictions both in the
U.S. and globally.  Though we are not currently a party to any such lawsuit, these suits present a high degree of uncertainty
regarding the extent to which energy companies,

- 16 -

Table of Contents

including offshore drillers, face an increased risk of liability stemming from climate change, which risk would also adversely
impact the oil and gas industry and impact demand for our services.

ANY  RESTRICTIONS  ON  OIL  AND  NATURAL  GAS  OPERATIONS  ON  THE  U.S.  OUTER  CONTINENTAL
SHELF  (“OCS”)  COULD  HAVE  AN  ADVERSE  IMPACT  ON  OUR  BUSINESS  AND  DEMAND  FOR  OUR
SERVICES.

The U.S. Department of the Interior (“DOI”) administers the submerged lands, subsoil, and seabed, lying between the
seaward extent of the states’ jurisdiction and the seaward extent of federal jurisdiction, and the U.S. government has the power
to limit oil and gas activities on this area, known as the OCS.  Under the Outer Continental Shelf Lands Act, as amended, the
BOEM within the DOI must prepare and maintain forward-looking five-year plans—referred to as national programs or five-
year programs—to schedule proposed oil and gas lease sales on the OCS.  On July 1, 2022, BOEM announced the availability
of  the  Proposed  Program  for  the  2023-2028  timeframe  for  public  comments.   The  Proposed  Program  includes  no  more  than
ten potential lease sales in the U.S. Gulf of Mexico.  Inclusion of an area in the Proposed Program is not a final indication that it
will be included in the approved 2023-2028 National OCS Program or offered in a lease sale.  In addition, the U.S. previously
placed a moratorium on new oil and natural gas leases on federal lands and waters, including the federal OCS.  Future actions
taken by the U.S. to limit the availability of new oil and gas leases on the OSC would adversely impact the offshore oil and gas
industry and impact demand for our services.

THE GLOBAL NATURE OF OUR OPERATIONS INVOLVES ADDITIONAL RISKS.

We  operate  in  various  regions  throughout  the  world,  which  may  expose  us  to  political  and  other  uncertainties,

including risks of:

◾ terrorist acts, war, piracy and civil unrest;
◾ seizure, expropriation or nationalization of our equipment or of our customers’ property;
◾ customs delays or disputes;
◾ repudiation or nationalization of contracts;
◾ imposition of trade or immigration barriers;
◾ import-export quotas;
◾ wage and price controls;
◾ changes in law and regulatory requirements, including changes in interpretation and enforcement;
◾ involvement in judicial proceedings in unfavorable jurisdictions;
◾ damage to our equipment or violence directed at our employees, including kidnappings;
◾ complications associated with supplying, repairing and replacing equipment in remote locations;
◾ public  health  threats,  including  pandemics  and  epidemics,  severe  influenza,  coronaviruses  and  other  highly  communicable

viruses or diseases;

◾ the inability to move income or capital; and
◾ currency exchange fluctuations and currency exchange restrictions, including exchange or similar controls that may limit our

ability to convert local currency into U.S. dollars and transfer funds out of a local jurisdiction.

Our  non-U.S.  contract  drilling  operations  are  subject  to  various  laws  and  regulations  related  to  economic  and  trade
sanctions in certain countries in which we operate, including laws and regulations relating to the import and export, equipment
and  operation  of  drilling  units,  currency  conversions  and  repatriation,  oil  and  gas  exploration  and  development,  taxation  and
social  contributions  of  offshore  earnings  and  earnings  of  expatriate  personnel.    We  are  also  subject  to  the  U.S.  Treasury
Department’s  Office  of  Foreign  Assets  Control  (“OFAC”)  and  other  U.S.  and  non-U.S.  laws  and  regulations  governing  our
international operations.  In addition, various state and municipal governments, universities and other investors have proposed
or  adopted  divestment  and  other  initiatives  regarding  investments  including,  with  respect  to  state  governments,  by  state
retirement systems in companies that do business with countries that have been designated as state sponsors of terrorism by the
U.S. State Department.  Failure to comply with applicable laws and regulations, including those relating to sanctions and export
restrictions, may subject us to criminal sanctions or civil remedies, including fines, denial of export privileges, injunctions or
seizures of assets.  Investors could view any potential violations of OFAC regulations negatively, which could adversely affect
our reputation and the market for our shares.

Governments  in  some  countries  have  become  increasingly  active  in  regulating  and  controlling  the  ownership  of
concessions and companies holding concessions, the exploration for oil and gas and other aspects of the oil and gas industries in
their  countries,  including  local  content  requirements  for  participating  in  tenders  for  certain  drilling  contracts.    Many
governments favor or effectively require the awarding of drilling contracts to local contractors or require nonlocal contractors to
employ citizens of, or purchase supplies from, a particular jurisdiction or require use of a local agent.  In addition, government
action,  including  initiatives  by  OPEC,  may  continue  to  cause  oil  or  gas  price  volatility.    In  some  areas  of  the  world,  this
governmental activity has adversely affected the amount of exploration and development work by major energy companies and
may continue to do so.

The shipment of goods, services and technology across international borders subjects us to extensive trade laws and
regulations.  Our import and export activities are governed by unique customs and export control laws and regulations in each
of  the  countries  where  we  operate.    Moreover,  many  countries,  including  the  U.S.,  control  the  import  and  export  of  certain
goods, services and technology and impose related import and export recordkeeping and reporting obligations.  Governments
also  may  impose  economic  sanctions  against  certain  countries,  persons  and  other  entities  that  may  restrict  or  prohibit
transactions involving such countries, persons and entities, and we are also subject to the U.S. anti-boycott laws.

Table of Contents

The  laws  and  regulations  concerning  import  and  export  activity,  recordkeeping  and  reporting,  import  and  export
control and economic sanctions are complex and constantly changing.  These laws and regulations may be enacted, amended,
enforced  or  interpreted  in  a  manner  materially  impacting  our  operations.    Ongoing  economic  challenges  may  increase  some
governments’ efforts to enact, enforce, amend or interpret laws and regulations as a method to increase revenue.  Shipments can
be delayed and denied import or export for a variety of reasons, some of which are outside our control and some of which may
result from failure to comply with existing legal and regulatory regimes.  Shipping delays or denials could cause unscheduled
operational downtime.

Our  results  are  directly  affected  by  the  applicability  of  certain  customs  duties  and  importation  tax  relief  programs
under customs regimes for the exportation and importation of goods and equipment, including rigs, related to the oil and gas
sector.  Among other incentives, such programs grant full suspension of certain import taxes, resulting in reduced tax burdens
from operations.  If unprecedented interpretations are applied by the customs and tax authorities governing  such programs and
regimes, including those that would deny us the use of such incentives granted historically in the ordinary course, and assuming
we are unable to successfully challenge such interpretation or otherwise able to recover any amounts pursuant to the contractual
provisions of the applicable drilling contract, then the amount of the applicable tariff, which would depend on many factors,
could reasonably be expected to increase our operating costs.

Our  ability  to  operate  worldwide  depends  on  our  ability  to  obtain  the  necessary  visas  and  work  permits  for  our
personnel to travel in and out of, and to work in, the jurisdictions in which we operate.  Governmental actions in some of the
jurisdictions  in  which  we  operate  may  make  it  difficult  for  us  to  move  our  personnel  in  and  out  of  these  jurisdictions  by
delaying or withholding the approval of these permits.  If we are not able to obtain visas and work permits for the employees we
need to conduct our operations on a timely basis, we might not be able to perform our obligations under our drilling contracts,
which could allow our customers to cancel the contracts.  If our customers cancel some of our drilling contracts, and we are
unable to secure new drilling contracts on a timely basis and on substantially similar terms, it could have a material adverse
effect on our business and on our financial position, results of operations or cash flows.

FAILURE  TO  COMPLY  WITH  ANTI-BRIBERY  STATUTES,  SUCH  AS  THE  U.S.  FOREIGN  CORRUPT
PRACTICES  ACT  AND  THE  U.K.  BRIBERY  ACT  2010,  COULD  RESULT  IN  FINES,  CRIMINAL  PENALTIES,
DRILLING CONTRACT TERMINATIONS AND AN ADVERSE EFFECT ON OUR BUSINESS.

The U.S. Foreign Corrupt Practices Act (“FCPA”), the U.K. Bribery Act 2010 (“Bribery Act”) and similar anti-bribery
laws  in  other  jurisdictions,  generally  prohibit  companies  and  their  intermediaries  from  making  improper  payments  for  the
purpose of obtaining or retaining business.  We operate in many parts of the world that have experienced corruption to some
degree and, in certain circumstances, strict compliance with anti-bribery laws may conflict with local customs and practices.  If
we  are  found  to  be  liable  for  violations  under  the  FCPA,  the  Bribery  Act  or  other  similar  laws,  either  due  to  our  acts  or
omissions or due to the acts or omissions of others, including our partners in our various joint ventures and of the current or
former officers, directors or employees of any companies we have acquired, we could suffer from civil and criminal penalties or
other sanctions, which could have a material adverse effect on our business or our financial position, results of operations or
cash flows.  In addition, investors could negatively view potential violations, inquiries or allegations of misconduct under the
FCPA, the Bribery Act or similar laws, which could adversely affect our reputation and the market for our shares.

We could also face fines, sanctions and other penalties from authorities in relevant jurisdictions, including prohibition
of  our  participating  in  or  curtailment  of  business  operations  in  those  jurisdictions  and  the  seizure  of  rigs  or  other  assets.
 Additionally,  our  business  and  results  of  operations  could  be  adversely  affected  as  a  result  of  claims  by  customers,  agents,
shareholders,  debt  holders,  other  interest  holders,  current  or  former  employees  or  other  constituents  of  our  company  who,  in
connection  with  alleged  or  actual  noncompliance  with  antibribery  and  related  laws,  may  seek  to  impose  penalties,  seek
remedies, terminate drilling contracts or take other actions adverse to our interests.  Our business and results of operations may
be  adversely  affected  if  we  are  required  to  dedicate  significant  time  and  resources  to  investigate  and  resolve  allegations  of
misconduct,  regardless  of  the  merit  of  such  allegations.    Further,  disclosure  of  the  subject  matter  of  any  investigation  could
adversely affect our reputation and our ability to obtain new business with potential customers, to retain existing business with
our current customers, to attract and retain employees and to access the capital markets.

WE ARE SUBJECT TO INVESTIGATIONS AND LITIGATION THAT, IF NOT RESOLVED IN OUR FAVOR AND
NOT SUFFICIENTLY INSURED AGAINST, COULD HAVE A MATERIAL ADVERSE EFFECT ON US.

We are subject to a variety of disputes, investigations and litigation.  Certain of our subsidiaries are subject to and have
been  involved  in  litigation  with  certain  of  our  customers  and  other  constituents.    Certain  of  our  subsidiaries  are  named  as
defendants in numerous lawsuits alleging personal grievances or injury, including as a result of exposure to asbestos or toxic
fumes  or  resulting  from  other  occupational  diseases,  such  as  silicosis,  and  various  other  medical  issues  that  can  remain
undiscovered for a considerable amount of time.  Some of these subsidiaries that have been put on notice of potential liabilities
have  no  assets.    Certain  subsidiaries  are  subject  to  litigation  relating  to  environmental  damage.    Our  patent  for  dual-activity
technology has been successfully challenged in certain jurisdictions.  We are also subject to a number of significant tax disputes.
 We cannot predict the outcome of these investigations and cases or the potential costs to resolve them.  Insurance may not be
applicable or sufficient in all cases, insurers may not remain solvent and policies may not be located.  Suits against non-asset-
owning subsidiaries have and may in the future give rise to alter ego or successor-in-interest claims against us and our asset-
owning subsidiaries to the extent a subsidiary is unable to pay a claim or insurance is not available or sufficient to cover the
claims.  To the extent that one or more pending or future investigations or litigation matters is not resolved in our favor and is
not  covered  by  insurance,  which  could  have  a  material  adverse  effect  on  our  financial  position,  results  of  operations  or  cash
flows.

WE  ARE  SUBJECT  TO  CYBERSECURITY  RISKS  AND  THREATS  AS  WELL  AS  INCREASING  REGULATION
OF DATA PRIVACY AND SECURITY.

We depend on data and digital technologies to conduct our offshore and onshore operations, to collect payments from
customers and to pay vendors and employees.  Our data protection measures and measures taken by our customers and vendors
may not prevent unauthorized access of information technology systems, and when such unauthorized access occurs, we, our
customers or vendors may not detect the incident in time to prevent harm or damage.  Threats to our information technology
systems,  and  the  systems  of  our  customers  and  vendors,  associated  with  cybersecurity  risks  and  cyber-incidents  or  attacks
continue to grow.  Such threats may derive from human error, fraud or malice, social engineering on the part of employees or
third  parties,  or  may  result  from  accidental  technological  failure.    In  addition,  breaches  to  our  systems  and  systems  of  our
customers and vendors could go unnoticed for some period of time.  Risks associated with these threats include disruptions of
certain systems on our rigs; other impairments of our ability to conduct our operations; loss or ransom of intellectual property,
proprietary  information,  personal  identifiable  information  or  customer  and  vendor  data;  disruption  of  our  customers’  and
vendors’  operations;  misappropriation  of  assets;  loss  or  damage  to  our  customer  and  vendor  data  delivery  systems;  and
increased costs to prevent, respond to or mitigate cybersecurity events.  A breach could also originate from, or compromise, our
customers’  and  vendors’  or  other  third-party  networks  outside  of  our  control.   A  breach  may  also  result  in  legal  claims  or
proceedings against us by our shareholders, employees, customers, vendors and governmental authorities, both U.S. and non-
U.S.  If such a cyber-incident were to occur, it could have a material adverse effect on our business or on our financial position,
results of operations or cash flows.

In  addition,  data  privacy  and  the  unauthorized  disclosure  of  personal  data  and  confidential  information  pose
increasingly  complex  compliance  challenges  and  have  the  potential  to  elevate  our  costs  under  various  laws  and  regulations,
including privacy regulations that have been adopted or may in the future be adopted by, or be applicable from time to time to,
countries, states, and other jurisdictions or authorities.  Any failure by us to comply with these laws and regulations, including
as a result of a security or privacy breach, could result in significant penalties, litigation and liabilities for us.  Additionally, if
we acquire a company that has violated or is not in compliance with applicable data protection laws, we may incur significant
liabilities and penalties as a result.

ACTS  OF  TERRORISM,  PIRACY  AND  POLITICAL  AND  SOCIAL  UNREST  COULD  AFFECT  THE  MARKETS
FOR DRILLING SERVICES.

Acts of terrorism and social unrest, brought about by world political events or otherwise, have caused instability in the
world’s financial and insurance markets in the past and may occur in the future.  Such acts could be directed against companies
such as ours.  In addition, acts of terrorism, piracy and social unrest could lead to increased volatility in prices for crude oil and
natural  gas  and  could  affect  the  markets  for  drilling  services.    Insurance  premiums  could  increase  and  coverage  may  be
unavailable in the future.  Government regulations may effectively preclude us from engaging in business activities in certain
countries.  These regulations could be amended to cover countries where we currently operate or where we may wish to operate
in the future.  Our drilling contracts do not generally provide indemnification against loss of capital assets or loss of revenues
resulting from acts of terrorism, piracy or political or social unrest.  We have limited insurance for our assets providing coverage
for  physical  damage  losses  resulting  from  certain  risks,  such  as  terrorist  acts,  piracy,  vandalism,  sabotage,  civil  unrest,
expropriation and acts of war, and we do not carry insurance for loss of revenues resulting from such risks.

RISKS RELATED TO TAXES

A CHANGE IN TAX LAWS, TREATIES OR REGULATIONS, OR THEIR INTERPRETATION, OF ANY COUNTRY
IN  WHICH  WE  HAVE  OPERATIONS,  ARE  INCORPORATED  OR  ARE  RESIDENT  COULD  RESULT  IN  A
HIGHER  EFFECTIVE  TAX  RATE  ON  OUR  CONSOLIDATED  EARNINGS  AND  INCREASE  OUR  CASH  TAX
PAYMENTS.

We are subject to changes in applicable tax laws, treaties or regulations in the jurisdictions in which we operate and
earn income, and such changes could include laws or policies directed toward companies organized in jurisdictions with low tax
rates with the intent to increase the tax burden.  Several jurisdictions have implemented or are expected to implement in the
future, the Organization for Economic Co-operation and Development Pillar 2 or other tax related provision that are aimed at
preventing  base  erosion  and  profit  shifting,  ensuring  income  is  subject  to  a  minimum  level  of  taxation  and  preventing  treaty
misuse.    The  application  of  these  provisions  is  not  always  certain,  and  jurisdictions  are  still  developing  their  rules  and
interpretations with regard to same.

As  such,  any  material  change  to  tax  laws,  treaties,  regulations  or  policies,  their  interpretation  or  application,  or  the
adoption of new interpretations of existing laws and rulings, in any of the jurisdictions in which we operate, are incorporated or
resident, could result in a higher effective tax rate on our worldwide earnings and such change could have a significant adverse
effect on our financial position, results of operations or cash flows.

A  LOSS  OF  A  MAJOR  TAX  DISPUTE  OR  A  SUCCESSFUL  TAX  CHALLENGE  TO  OUR  OPERATING
STRUCTURE,  INTERCOMPANY  PRICING  POLICIES  OR  THE  TAXABLE  PRESENCE  OF  OUR  KEY
SUBSIDIARIES  IN  CERTAIN  COUNTRIES  COULD  RESULT  IN  A  HIGHER  EFFECTIVE  TAX  RATE  ON  OUR
CONSOLIDATED EARNINGS AND INCREASE OUR CASH TAX PAYMENTS.

We are subject to tax laws, treaties and regulations in the countries in which we operate and earn income.  Our income
taxes are based on the applicable tax laws and tax rates in effect in the countries in which we operate and earn income as well as
upon  our  operating  structures  in  these  countries.    Our  income  tax  returns  are  subject  to  review  and  examination  in  these
jurisdictions, and we do not recognize the benefit of income tax positions we believe are more likely than not to be disallowed
upon challenge by a tax authority.  If any tax authority successfully challenges our operational structure, intercompany pricing
policies or the taxable presence of our key subsidiaries in certain

- 19 -

Table of Contents

countries; or if the terms of certain income tax treaties are interpreted in a manner that is adverse to our structure; or if we lose a
material  tax  dispute  in  any  country,  our  effective  tax  rate  on  our  worldwide  earnings  could  increase  substantially  and  our
earnings and cash flows from operations could be materially adversely affected.  For example, we believe that neither we nor
our non-U.S. subsidiaries, other than those that report a U.S. trade or business or a U.S. permanent establishment, were or are
engaged in a trade or business in the U.S. or, if applicable, maintained or maintain a permanent establishment in the U.S.  The
determination  of  the  aforementioned,  among  other  things,  involves  considerable  uncertainty.    If  the  U.S.  Internal  Revenue
Service were to disagree, then we could be subject to additional U.S. corporate income and branch profits taxes on the portion
of our earnings effectively connected to such U.S. business or, if applicable, attributable to such U.S. permanent establishment
during the period in which this was considered to have occurred.  If this occurs, our effective tax rate on worldwide earnings for
that period could increase substantially, we could be subject to assessments in previously filed returns that remain open to audit
and our earnings and cash flows from operations for that period could be adversely affected.

RISKS RELATED TO OUR JURISDICTION OF ORGANIZATION AND GOVERNING DOCUMENTS

AS A SWISS CORPORATION, OUR FLEXIBILITY MAY BE LIMITED WITH RESPECT TO CERTAIN ASPECTS
OF CAPITAL MANAGEMENT AND SWIFT IMPLEMENTATION OF CERTAIN INITIATIVES OR STRATEGIES.

Under Swiss law, our shareholders may approve a general share capital authorization, referred to under Swiss law as a
capital band, that allows the board of directors to issue new shares without additional shareholder approval within a period of up
to  five  years  and  for  up  to  a  maximum  of  50  percent  of  a  company’s  issued  share  capital.    The  general  share  capital
authorization  approved  by  our  shareholders  at  the  May  2023  annual  general  meeting  will  expire  on  May  11,  2024.    Our
currently available authority under this general share capital authorization is equivalent to approximately 17.5 percent of our
issued share capital as of February 14, 2024.  Accordingly, shareholders at our annual general meeting in May 2024 may be
requested to approve a renewal and increase of our general share capital authorization for an additional term.  Subject to certain
exceptions, Swiss law also grants preemptive rights to existing shareholders to subscribe for new issuances of shares.  Further,
Swiss law does not provide as much flexibility in the various terms that can attach to different classes of shares as the laws of
some  other  jurisdictions.    Swiss  law  also  reserves  for  shareholder  approval  certain  corporate  actions,  such  as  approval  of
dividends,  over  which  a  board  of  directors  would  have  authority  in  some  other  jurisdictions.   These  Swiss  law  requirements
relating to our capital management may limit our flexibility to swiftly implement certain initiatives or strategies, and situations
may arise where greater flexibility would have provided substantial benefits to our shareholders.

We are required, from time to time, to evaluate the carrying amount of our investments in affiliates, as presented on our
Swiss standalone balance sheet.  If we determine that the carrying amount of any such investment exceeds its fair value, we may
conclude that such investment is impaired.  Any recognized loss associated with such a non-cash impairment could result in our
net assets no longer covering our statutory share capital and statutory capital reserves.  Under Swiss law, if our net assets cover
less than 50 percent of our statutory share capital and the non-distributable part of the statutory capital and profit reserves, the
board  of  directors  must  take  appropriate  measures  or,  to  the  extent  such  measures  fall  within  the  competence  of  the  general
meeting  of  shareholders,  convene  a  general  meeting  of  shareholders,  and  propose  measures  to  remedy  such  a  capital  loss.
 Appropriate measures depend on the relevant circumstances and the magnitude of the recognized loss and may include seeking
shareholder  approval  for  offsetting  the  aggregate  loss,  or  a  portion  thereof,  with  our  statutory  capital  reserves,  including
qualifying additional paid-in capital otherwise available for distributions to shareholders, or raising new equity.  Depending on
the circumstances, we may also need to use qualifying additional paid-in capital available for distributions in order to reduce
our  accumulated  net  loss  and  such  use  might  reduce  our  ability  to  make  distributions  without  subjecting  our  shareholders  to
Swiss withholding tax.

Distributions  to  shareholders  in  the  form  of  a  par  value  reduction  and  dividend  distributions  out  of  qualifying
additional  paid-in  capital  are  currently  not  subject  to  the  35  percent  Swiss  federal  withholding  tax.    However,  the  Swiss
withholding  tax  rules  could  be  changed  in  the  future,  and  any  such  change  may  adversely  affect  us  or  our  shareholders.    In
addition, over the long term, the amount of par value available for us to use for par value reductions or the amount of qualifying
additional paid-in capital available for us to pay out as distributions is limited.  If we are unable to make a distribution through a
reduction in par value, or out of qualifying additional paid-in capital as shown on Transocean Ltd.’s standalone Swiss statutory
financial statements, we may not be able to make distributions without subjecting our shareholders to Swiss withholding taxes.

Under  Swiss  tax  law,  repurchases  of  shares  for  the  purposes  of  capital  reduction  are  treated  as  a  partial  liquidation
subject to a 35 percent Swiss withholding tax based on the difference between the repurchase price and the related amount of
par  value  and  the  related  amount  of  qualifying  additional  paid-in  capital,  if  any.   At  our  2009  annual  general  meeting,  our
shareholders  approved  the  repurchase  of  up  to  CHF  3.50  billion  of  our  shares  for  cancellation  under  the  share  repurchase
program.    If  we  repurchase  shares,  we  expect  to  use  an  alternative  procedure  pursuant  to  which  we  repurchase  shares  via  a
“virtual second trading line” from market players, such as banks and institutional investors, who are generally entitled to receive
a  full  refund  of  the  Swiss  withholding  tax.    The  use  of  such  “virtual  second  trading  line”  with  respect  to  share  repurchase
programs is subject to the approval of the competent Swiss tax and other authorities.  We may not be able to repurchase as many
shares as we would like to repurchase for purposes of capital reduction on the “virtual second trading line” without subjecting
the selling shareholders to Swiss withholding taxes.

WE ARE SUBJECT TO ANTI-TAKEOVER PROVISIONS.

Our articles of association and Swiss law contain provisions that could prevent or delay an acquisition of the company
by means of a tender offer, a proxy contest or otherwise.  Actions taken under such provisions may adversely affect prevailing
market prices for our shares, and could, among other things:

◾ provide that the board of directors is authorized to issue a specified number of shares, which under our current general share
capital authorization as of February 14, 2024 is approximately 17.5 percent of the share capital registered in the commercial
register,  and  to  limit  or  withdraw  the  preemptive  rights  of  existing  shareholders  in  various  circumstances.    Pursuant  to  the
terms of the current general share capital authorization, the board’s authority to issue new shares expires on May 11, 2024,
subject to shareholders approving a renewal or increase of this authorization in accordance with the current company practice;
◾ provide  for  a  conditional  share  capital  that  authorizes  the  issuance  of  additional  shares  up  to  a  maximum  amount  of
approximately 16.9 percent of the share capital registered in the commercial register as of February 14, 2024 without obtaining
additional  shareholder  approval  through:  (1)  the  exercise  of  conversion,  exchange,  option,  warrant  or  similar  rights  for  the
subscription  of  shares  granted  in  connection  with  bonds,  options,  warrants  or  other  securities  newly  or  already  issued  in
national or international capital markets or new or already existing contractual obligations by or of any of our subsidiaries; or
(2) in connection with the issuance of shares, options or other share-based awards;

◾ provide that any shareholder who wishes to propose any business or to nominate a person or persons for election as director at

any annual meeting may only do so if we are given advance notice;

◾ provide that directors can be removed from office only by the affirmative vote of the holders of at least 66 2/3 percent of the

shares entitled to vote;

◾ provide  that  a  merger  or  demerger  transaction  requires  the  affirmative  vote  of  the  holders  of  at  least  66  2/3  percent  of  the
shares represented at the meeting and provide for the possibility of a so-called cash-out or squeeze-out merger if the acquirer
controls 90 percent of the outstanding shares entitled to vote at the meeting;

◾ provide  that  any  action  required  or  permitted  to  be  taken  by  the  holders  of  shares  must  be  taken  at  a  duly  called  annual  or

extraordinary general meeting of shareholders;

◾ limit the ability of our shareholders to amend or repeal some provisions of our articles of association; and
◾ limit transactions between us and an “interested shareholder,” which is generally defined as a shareholder that, together with its
affiliates and associates, beneficially, directly or indirectly, owns 15 percent or more of our shares entitled to vote at a general
meeting.

ITEM 1C.CYBERSECURITY

RISK MANAGEMENT AND STRATEGY

Our  approach  to  managing  cybersecurity  risk  and  safeguarding  information  across  our  organization  embeds  data
protection  and  cybersecurity  risk  management  throughout  our  enterprise  and  daily  operations.    We  maintain  processes  for
identifying,  assessing  and  managing  material  risks,  including  such  risks  from  cybersecurity  threats,  and  such  processes  are
integrated into our overall risk management system.  Our enterprise risk register inventories significant risks to our company,
including significant cybersecurity risks, and we maintain a separate functional risk register, specifically focusing on potential
cybersecurity risks.  Within these risk registers, we record each identified risk, describe its likelihood of occurrence and assess
its  potential  impact,  including  the  materiality  thereof.    As  part  of  this  exercise,  mitigating  measures  are  planned  and
implemented into action as necessary.  As an additional feature of our cybersecurity risk management process, we have engaged
an external third-party service provider to support our cybersecurity team and perform certain periodic external evaluations in
addition to the assessments and network penetration tests we perform internally.

We undertake to align our cybersecurity program, which encompasses both enterprise security and operational security,
with the standards of the National Institute of Standards and Technology Cybersecurity Framework.  We maintain continuous
cyber  threat-detection  systems  and  have  established  an  incident  response  plan,  which  contains  playbooks  for  addressing  and
recovering from potential material cyberattacks and breaches of data security.  In addition to security measures for third-party
vendors,  we  require  onboarding  orientation  and  periodic  training  covering  cybersecurity  and  information  management  for  all
employees and board members and conduct regular cybersecurity awareness campaigns.

As of the date of our filing of this report, we are not aware of any cybersecurity incident that has had or is reasonably
likely  to  have  a  material  impact  on  our  business  operations.    Given  the  rapid  evolution  of  cyber-related  attack  techniques,
cybersecurity risks associated with our information technology systems and the systems of our customers and vendors continue
to  grow.    Notwithstanding  our  cybersecurity  management  processes,  a  future  cybersecurity  incident  could  have  a  material
adverse effect on our business or on our financial position, results of operations or cash flows.  See “Item 1A. Risk Factors—
Risks related to laws, regulation, and governmental compliance—We are subject to cybersecurity risks and threats as well as
increasing regulation of data privacy and security.”

Table of Contents

GOVERNANCE

We  involve  multiple  levels  of  oversight  as  a  part  of  our  approach  to  cybersecurity  risk  management.    Our  board  of
directors oversees our enterprise risk register and cybersecurity program, including related policies and procedures.  As part of
this oversight, the audit committee of our board of directors receives regular status reports and updates from our management
team and conducts periodic executive sessions with our Chief Information Officer.  Such status reports and executive sessions
cover cybersecurity matters, such as developments to our program, key risk indicators, emerging risks, and identified incidents.

In addition, our Chief Information Officer, who has more than 40 years of industry experience and over 20 years of
experience  with  the  development,  training  and  controls  of  effective  global  enterprise  cybersecurity  programs,  oversees  the
implementation  and  compliance  of  our  cybersecurity  program  and  mitigation  of  information  security  related  risks.    Such
oversight includes (i) reviewing our enterprise risk register, (ii) maintaining adequate processes to manage the identified risks
under our cybersecurity program, (iii) regularly analyzing logs of cybersecurity threats and vulnerabilities and (iv) overseeing
prevention, detection, mitigation and remediation efforts in general, including the development and maintenance of the above-
mentioned  incident  response  plan.   Additionally,  we  maintain  an  experienced  information  technology  team  at  the  employee
level  that  supports  our  Chief  Information  Officer  in  implementing  our  cybersecurity  program  and  internal  reporting,  security
and mitigation functions.

ITEM 2. PROPERTIES

The description of our property included under “Item 1. Business” is incorporated by reference herein.  We maintain
offices, land bases and other facilities worldwide, most of which we lease, including principal executive offices in Steinhausen,
Switzerland,  and  corporate  offices  in  Houston,  Texas,  and  the  Cayman  Islands.   We  maintain  additional  offices  and  bases  in
various countries in North America, Europe, South America, Asia, Africa and Australia.

ITEM 3. LEGAL PROCEEDINGS

We  have  certain  actions,  claims  and  other  matters  pending  as  discussed  and  reported  in  “Part  II.  Item  8.  Financial
Statements  and  Supplementary  Data—Notes 
to  Consolidated  Financial  Statements—Note  13—Commitments  and
Contingencies” and “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations
—Other  Matters—Regulatory  Matters”  in  our  annual  report  on  Form  10-K.    We  are  also  involved  in  various  tax  matters  as
described  in  “Part  II.  Item  8.  Financial  Statements  and  Supplementary  Data—Notes  to  Consolidated  Financial  Statements—
Note 11—Income Taxes” and in “Part II. Item 7. Management’s Discussion and Analysis of Financial Condition and Results of
Operations—Other Matters—Tax matters” in this annual report on Form 10-K.  All such actions, claims, tax and other matters
disclosed therein are incorporated herein by reference.

As of December 31, 2023, we were involved in a number of other lawsuits, regulatory matters, disputes and claims,
asserted and unasserted, all of which constitute ordinary routine litigation incidental to our business and for which we do not
expect the liability, if any, to have a material adverse effect on our consolidated financial position, results of operations or cash
flows.    We  cannot  predict  with  certainty  the  outcome  or  effect  of  any  of  the  matters  referred  to  above  or  of  any  such  other
pending, threatened or possible litigation or legal proceedings.  We can provide no assurance that our beliefs or expectations as
to the outcome or effect of any lawsuit or claim or dispute will prove correct, and the eventual outcome of these matters could
materially differ from management’s current estimates.

On  December  17,  2021,  Transocean  Offshore  Deepwater  Drilling  Inc.  (“TODDI”),  our  wholly  owned  subsidiary,
received a letter from the U.S. Department of Justice (the “DOJ”) related to alleged violations by our subsidiary of its Clean
Water Act (“CWA”) National Pollutant Discharge Elimination System permit for the western Gulf of Mexico (“Permit”).  The
alleged  violations,  involving  seven  of  our  drillships,  were  identified  by  the  U.S.  Environmental  Protection  Agency  (“EPA”)
following an initial inspection in 2018 of our compliance with the Permit and the CWA and relate to deficiencies with respect to
administrative monitoring and reporting obligations.  In connection with the initial EPA inspection, we initiated modifications to
our Permit and CWA compliance processes and maintained a dialogue with the EPA regarding the design and implementation of
enhancements to these processes.  At the DOJ’s invitation, in an effort to resolve the matter, we initiated settlement discussions
with  the  DOJ,  which  concluded  with  the  execution  of  a  civil  consent  decree  by  and  between  the  DOJ,  EPA,  and  TODDI,
effective January 6, 2024 (the “Consent Decree”), that resolved the claims of the DOJ based upon the alleged violations of our
Permit and the CWA.  Pursuant to the Consent Decree, we agreed to pay an immaterial monetary civil penalty, and we further
agreed  (i)  to  take  or  continue  to  take  certain  corrective  actions  to  ensure  current  and  future  Permit  and  CWA  compliance,
including implementing certain procedures and submitting reports and other information, in each case according to the timelines
and as described in the Consent Decree, (ii) to appoint an independent auditor to review, audit and report on our compliance
with certain of our obligations thereunder, and (iii) to certain non-exclusive stipulated monetary penalties if we fail to comply
with  applicable  provisions  of  the  Consent  Decree.    We  may  request  termination  of  the  Consent  Decree  after  we  have
(x)  completed  timely  the  civil  penalty  payment  and  any  accrued  stipulated  penalty  requirements  of  the  Consent  Decree,  and
(y) maintained continuous satisfactory compliance with the Consent Decree for at least three years.  We do not believe that the
enforcement  of  the  Consent  Decree  would  have  a  material  adverse  effect  on  our  consolidated  financial  position,  results  of
operations or cash flows.

In addition to the legal proceedings described above, we may from time to time identify other matters that we monitor
through our compliance program or in response to events arising generally within our industry and in the markets where we do
business.  We evaluate

Table of Contents

matters  on  a  case-by-case  basis,  investigate  allegations  in  accordance  with  our  policies  and  cooperate  with  applicable
governmental authorities.  Through the process of monitoring and proactive investigation, we strive to ensure no violation of
our policies, Code of Integrity or law has occurred, or will occur; however, we can provide no assurance as to the outcome of
these matters.

PART II
ITEM 5. MARKET FOR REGISTRANT’S COMMON EQUITY, RELATED SHAREHOLDER MATTERS

AND ISSUER PURCHASES OF EQUITY SECURITIES

MARKET FOR SHARES OF OUR COMMON EQUITY

Our shares are listed on the New York Stock Exchange under the ticker symbol “RIG.”  On February 14, 2024, we had

809,030,846 shares outstanding and 4,694 holders of record of our shares.

SHAREHOLDER MATTERS

Swiss tax consequences to our shareholders

Overview—The  tax  consequences  discussed  below  are  not  a  complete  analysis  or  listing  of  all  the  possible  tax
consequences that may be relevant to our shareholders.  Shareholders should consult their own tax advisors in respect of the tax
consequences related to receipt, ownership, purchase or sale or other disposition of our shares and the procedures for claiming a
refund of withholding tax.

Swiss income tax on dividends and similar distributions—A non-Swiss holder is not subject to Swiss income taxes
on  dividend  income  and  similar  distributions  in  respect  of  our  shares,  unless  the  shares  are  attributable  to  a  permanent
establishment or a fixed place of business maintained in Switzerland by such non-Swiss holder.  However, dividends and similar
distributions are subject to Swiss withholding tax, subject to certain exceptions.  See “—Swiss withholding tax on dividends
and similar distributions to shareholders.”

Swiss wealth tax—A non-Swiss holder is not subject to Swiss wealth taxes unless the holder’s shares are attributable

to a permanent establishment or a fixed place of business maintained in Switzerland by such non-Swiss holder.

Swiss capital gains tax upon disposal of shares—A non-Swiss holder is not subject to Swiss income taxes for capital
gains  unless  the  holder’s  shares  are  attributable  to  a  permanent  establishment  or  a  fixed  place  of  business  maintained  in
Switzerland by such non-Swiss holder.  In such case, the non-Swiss holder is required to recognize capital gains or losses on the
sale of such shares, which are subject to cantonal, communal and federal income tax.

Swiss  withholding  tax  on  dividends  and  similar  distributions  to  shareholders—A  Swiss  withholding  tax  of
35 percent is due on dividends and similar distributions to our shareholders from us, regardless of the place of residency of the
shareholder, subject to the exceptions discussed under “—Exemption” below.  We will be required to withhold at such rate and
remit  on  a  net  basis  any  payments  made  to  a  holder  of  our  shares  and  pay  such  withheld  amounts  to  the  Swiss  federal  tax
authorities.

Exemption—Distributions to shareholders in the form of a par value reduction or out of qualifying additional paid-in
capital for Swiss statutory purposes are exempt from Swiss withholding tax.  On December 31, 2023, the aggregate amount of
par value of our outstanding shares was CHF 80.9 million, equivalent to approximately $96.2 million, and the aggregate amount
of  qualifying  additional  paid-in  capital  of  our  outstanding  shares  was  CHF  14.4  billion,  equivalent  to  approximately
$17.1  billion.    Consequently,  we  expect  that  a  substantial  amount  of  any  potential  future  distributions  may  be  exempt  from
Swiss withholding tax.

Refund available to Swiss holders—A Swiss tax resident, corporate or individual, can recover the withholding tax in
full if such resident is the beneficial owner of our shares at the time the dividend or other distribution becomes due and provided
that  such  resident  reports  the  gross  distribution  received  on  such  resident’s  income  tax  return,  or  in  the  case  of  an  entity,
includes the taxable income in such resident’s income statement.

Refund  available  to  non-Swiss  holders—If  the  shareholder  that  receives  a  distribution  from  us  is  not  a  Swiss  tax
resident,  does  not  hold  our  shares  in  connection  with  a  permanent  establishment  or  a  fixed  place  of  business  maintained  in
Switzerland,  and  resides  in  a  country  that  has  concluded  a  treaty  for  the  avoidance  of  double  taxation  with  Switzerland  for
which the conditions for the application and protection of and by the treaty are met, then the shareholder may be entitled to a
full or partial refund of the withholding tax described above.  Switzerland has entered into bilateral treaties for the avoidance of
double  taxation  with  respect  to  income  taxes  with  numerous  countries,  including  the  United  States  (“U.S.”),  whereby  under
certain circumstances all or part of the withholding tax may be refunded.  The procedures for claiming treaty refunds, and the
time frame required for obtaining a refund, may differ from country to country.

Refund available to U.S. residents—The Swiss-U.S. tax treaty provides that U.S. residents eligible for benefits under
the treaty can seek a refund of the Swiss withholding tax on dividends for the portion exceeding 15 percent, leading to a refund
of 20 percent, or a 100 percent refund in the case of qualified pension funds.  As a general rule, the refund will be granted under
the treaty if the U.S. resident can show evidence of the following: (a) beneficial ownership, (b) U.S. residency and (c) meeting
the U.S.-Swiss tax treaty’s limitation on benefits requirements.  The claim for refund must be filed with the Swiss federal tax
authorities (Eigerstrasse 65, 3003 Bern, Switzerland), not later than December 31 of the third year following the year in which
the dividend payments became due.  The relevant Swiss tax form is Form 82C for companies, 82E for other entities and 82I for
individuals.    These  forms  can  be  obtained  from  any  Swiss  Consulate  General  in  the  U.S.  or  from  the  Swiss  federal  tax
authorities at the above address or can be downloaded from the webpage of the Swiss federal tax administration.  Each form
must be completed in triplicate, with each copy duly completed and signed before a notary public in the U.S.  Evidence that the
withholding tax was withheld at the source must also be included.

Table of Contents

Stamp  duties  in  relation  to  the  transfer  of  shares—The  purchase  or  sale  of  our  shares  may  be  subject  to  Swiss
federal stamp taxes on the transfer of securities irrespective of the place of residency of the purchaser or seller if the transaction
takes place through or with a Swiss bank or other Swiss securities dealer, as those terms are defined in the Swiss Federal Stamp
Tax Act and no exemption applies in the specific case.  If a purchase or sale is not entered into through or with a Swiss bank or
other  Swiss  securities  dealer,  then  no  stamp  tax  will  be  due.   The  applicable  stamp  tax  rate  is  0.075  percent  for  each  of  the
two parties to a transaction and is calculated based on the purchase price or sale proceeds.  If the transaction does not involve
cash consideration, the transfer stamp duty is computed on the basis of the market value of the consideration.

Share repurchases

Overview—Shares  repurchased  for  the  purpose  of  capital  reduction  are  treated  as  a  partial  liquidation  subject  to  a
35 percent Swiss withholding tax based on the difference between the repurchase price and the related amount of par value and
the related amount of qualifying additional paid-in capital, if any.  We would be required to remit on a net basis the purchase
price with the Swiss withholding tax deducted to a holder of our shares and pay the withholding tax to the Swiss federal tax
authorities.  However, for such repurchased shares, the portions of the repurchase price that are attributable to the par value and
the qualifying additional paid-in capital for Swiss statutory reporting purposes are not subject to the Swiss withholding tax.

If we repurchase shares, we expect to use an alternative procedure pursuant to which we repurchase our shares via a
"virtual second trading line" from market players, such as banks and institutional investors, who are generally entitled to receive
a  full  refund  of  the  Swiss  withholding  tax.    The  use  of  such  “virtual  second  trading  line”  with  respect  to  share  repurchase
programs is subject to approval of the competent Swiss tax and other authorities.  We may not be able to repurchase as many
shares as we would like to repurchase for purposes of capital reduction on the “virtual second trading line” without subjecting
the selling shareholders to Swiss withholding taxes.  The repurchase of shares for purposes other than for cancellation, such as
to retain as treasury shares for use in connection with stock incentive plans, convertible debt or other instruments within certain
periods,  are  not  generally  subject  to  Swiss  withholding  tax.    In  addition,  in  December  2022,  the  U.S.  Department  of  the
Treasury  released  proposed  regulations  under  the  Inflation  Reduction  Act,  whereby  an  excise  tax  of  one  percent  would  be
imposed on stock repurchases in the event one of our U.S. subsidiaries funds the stock repurchase.

Under Swiss corporate law, the right of a company and its subsidiaries to repurchase and hold its own shares is limited.
 A company may repurchase its shares to the extent it has freely distributable reserves as shown on its Swiss statutory balance
sheet in the amount of the purchase price and if the aggregate par value of all shares held by the company as treasury shares
does not exceed 10 percent of the company’s share capital recorded in the Swiss Commercial Register, whereby for purposes of
determining  whether  the  10  percent  threshold  has  been  reached,  shares  repurchased  under  a  share  repurchase  program  for
cancellation purposes authorized by the company’s shareholders are disregarded.  As of February 14, 2024, Transocean Inc., our
wholly owned subsidiary, held as treasury shares 4.11 percent of our issued shares.  Our board of directors could, to the extent
freely  distributable  reserves  are  available,  authorize  the  repurchase  of  additional  shares  for  purposes  other  than  cancellation,
such as to retain treasury shares for use in satisfying our obligations in connection with incentive plans or other rights to acquire
our shares.  Based on the number of shares held as treasury shares as of February 14, 2024, 5.89 percent of our issued shares
could be repurchased for purposes of retention as additional treasury shares.  Although our board of directors has not approved
such a share repurchase program for the purpose of retaining repurchased shares as treasury shares, if it did so, any such shares
repurchased would be in addition to any shares repurchased under the currently approved program.

Share repurchase program—In May 2009, at our annual general meeting, our shareholders approved and authorized
our board of directors, at its discretion, to repurchase for cancellation any amount of our shares for an aggregate purchase price
of up to CHF 3.50 billion.  On February 12, 2010, our board of directors authorized our management to implement the share
repurchase  program.    At  December  31,  2023,  the  authorization  remaining  under  the  share  repurchase  program  was  for  the
repurchase of our outstanding shares for an aggregate purchase price of up to CHF 3.24 billion, equivalent to $3.85 billion.  We
intend to fund any repurchases using available cash balances and cash from operating activities.  The share repurchase program
could be suspended or discontinued by our board of directors or company management, as applicable, at any time.  We may
decide,  based  on  our  ongoing  capital  requirements,  the  price  of  our  shares,  regulatory  and  tax  considerations,  cash  flow
generation,  the  amount  and  duration  of  our  contract  backlog,  general  market  conditions,  debt  rating  considerations  and  other
factors,  that  we  should  retain  cash,  reduce  debt,  make  capital  investments  or  acquisitions  or  otherwise  use  cash  for  general
corporate purposes.  Decisions regarding the amount, if any, and timing of any share repurchases will be made from time to
time based on these factors.  Any repurchased shares under the share repurchase program would be held by us for cancellation
by the shareholders at a future general meeting of shareholders.

ITEM 6. RESERVED

ITEM 7. MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND

RESULTS OF OPERATIONS

INTRODUCTION

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,”
“we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas  wells.    As  of
February 14, 2024, we owned or had partial ownership interests in and operated 37 mobile offshore drilling units, consisting of
28 ultra-deepwater floaters and nine harsh environment floaters.  Additionally, as of February 14, 2024, we were constructing
one ultra-deepwater drillship.

We  provide,  as  our  primary  business,  contract  drilling  services  in  a  single  operating  segment,  which  involves
contracting  our  mobile  offshore  drilling  rigs,  related  equipment  and  work  crews  to  drill  oil  and  gas  wells.   We  specialize  in
technically  demanding  regions  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 used in support of offshore drilling activities and offshore support services on a worldwide basis.

We  perform  contract  drilling  services  by  deploying  our  high-specification  fleet  in  a  single,  global  market  that  is
geographically dispersed in oil and gas exploration and development areas throughout the world.  Although rigs can be moved
from one region to another, the cost of moving rigs and the availability of rig-moving vessels may cause the supply and demand
balance to fluctuate somewhat between regions.  Still, significant variations between regions do not tend to persist long term
because  of  rig  mobility.    The  location  of  our  rigs  and  the  allocation  of  resources  to  operate,  build  or  upgrade  our  rigs  are
determined by the activities and needs of our customers.

The  information  contained  in  this  section  should  be  read  in  conjunction  with  the  information  contained  in  “Part  I.
Item  1.  Business,”  “Part  I.  Item  1A.  Risk  Factors”  and  the  audited  consolidated  financial  statements  and  the  notes  thereto
included under “Item 8. Financial Statements and Supplementary Data”  elsewhere  in  this  annual  report  on  Form  10-K.   The
following discussion of our results of operations and liquidity and capital resources includes comparisons for the years ended
December 31, 2023 and 2022.  For a discussion, including comparisons, of our results of operations and liquidity and capital
resources  for  the  years  ended  December  31,  2022  and  2021,  see  “Part  II.  Item  7.  Management’s  Discussion  and  Analysis  of
Financial Condition and Results of Operations” of our annual report on Form 10-K for the year ended December 31, 2022, filed
with the United States (“U.S.”) Securities and Exchange Commission on February 23, 2023.

SIGNIFICANT EVENTS

Fleet expansion—In May 2023, we completed the construction of and placed into service the ultra-deepwater floater
Deepwater Titan,  the  first  drillship  equipped  with  two  20,000  psi  blowout  preventers.   Additionally,  in  September  2023,  we
issued 11.9 million Transocean Ltd. shares with an aggregate value of $99 million to acquire the outstanding ownership interests
of Liquila Ventures Ltd. (together with its subsidiaries, “Liquila”), a previously unconsolidated variable interest entity that is
constructing the ultra-deepwater drillship Deepwater Aquila, and as a result, Liquila became our wholly owned subsidiary.  See
“—Liquidity and Capital Resources—Sources and uses of liquidity.”

Secured  debt  issuance—In  January  2023,  we  issued  $525  million  aggregate  principal  amount  of  8.375%  senior
secured notes due February 2028 (the “8.375% Senior Secured Notes”), and we received $516 million aggregate cash proceeds,
net of issue costs.  In January 2023, we issued $1.175 billion aggregate principal amount of 8.75% senior secured notes due
February 2030 (the “8.75% Senior Secured Notes”), and we received $1.148 billion aggregate cash proceeds, net of issue costs.
 In October 2023, we issued $325 million aggregate principal amount of 8.00% senior secured notes due September 2028 (the
“8.00% Senior Secured Notes”), and we received $319 million aggregate cash proceeds, net of issue costs.  See “—Liquidity
and Capital Resources—Sources and uses of liquidity.”

Early  debt  retirement—In  January  2023,  in  connection  with  the  issuance  of  the  8.75%  Senior  Secured  Notes,  we
made  an  aggregate  cash  payment  of  $1.159  billion,  including  a  make-whole  premium,  to  redeem  the  remaining  outstanding
$311 million, $240 million, $250 million, and $336 million aggregate principal amount of the 5.875% senior secured notes due
January 2024, the 7.75% senior secured notes due October 2024, the 6.25% senior secured notes due December 2024  and the
6.125% senior secured notes due August 2025, respectively.  In the year ended December 31, 2023, we made a cash payment of
$243  million  to  redeem  an  equivalent  aggregate  principal  amount  of  the  outstanding  5.375%  senior  secured  notes  due
May 2023.  See “—Liquidity and Capital Resources—Sources and uses of liquidity.”

Exchanged bonds—In the year ended December 31, 2023, holders of the outstanding $238 million aggregate principal
amount of the 2.50% senior guaranteed exchangeable bonds due January 2027 (the “2.50% Senior Guaranteed Exchangeable
Bonds”)  exchanged  such  bonds  under  the  terms  of  the  governing  indenture,  and  as  part  of  the  transactions,  we  delivered
38.6 million Transocean Ltd. shares.  In October 2023, our wholly owned subsidiary, Transocean Inc., entered into individually
negotiated agreements with holders of $60 million and $41 million aggregate principal amount of the 4.00% senior guaranteed
exchangeable  bonds  due  December  2025  (the  “4.00%  Senior  Guaranteed  Exchangeable  Bonds”)  and  the  4.625%  senior
guaranteed exchangeable bonds due September 2029 (the “4.625% Senior Guaranteed Exchangeable Bonds”), respectively and,
as  part  of  the  transactions,  we  delivered  26.5  million  Transocean  Ltd.  shares  to  such  holders.  See  “—Liquidity  and  Capital
Resources—Sources and uses of liquidity.”

Asset  disposal  and  investment  in  unconsolidated  affiliate—In  February  2023,  we  made  a  cash  contribution  of
$10 million and a non-cash contribution of the ultra-deepwater floater Ocean Rig Olympia, and related assets, with an estimated
fair value of $85 million, in exchange for an equity ownership interest in Global Sea Mineral Resources NV (together with its
subsidiaries, “GSR”).  In the year ended December 31, 2023, we recognized a loss of $169 million, which had no tax effect,
associated with the disposal of the rig and related assets.  See “—Operating Results,” “—Liquidity  and  Capital  Resources—
Sources and uses of liquidity”.

Impairment and disposal of assets held for sale—In the year ended December 31, 2023, we recognized an aggregate
loss of $57 million, which had no tax effect, associated with the impairment of the harsh environment floaters Paul B. Loyd, Jr.
and Transocean Leader and related assets, which we determined were impaired at the time that we classified the assets as held
for sale.  On February 15, 2024, we completed the sale of Paul B. Loyd, Jr. and Transocean Leader and related assets.  See “—
Operating Results” and “—Liquidity and Capital Resources—Sources and uses of liquidity.”

OUTLOOK

Drilling market—Our industry outlook is positive based upon underlying economic factors, including numerous long-
term  forecasts  that  indicate  hydrocarbons  will  continue  to  be  a  critical  source  of  energy  for  the  foreseeable  future,  despite
significant relative growth in alternative energy technologies, which remain less economical versus hydrocarbons.  Economic
forecasts  indicate  that  countries  that  are  not  members  of  the  Organization  for  Economic  Co-operation  and  Development  will
continue to experience population growth and improvement in living standards, which will compound the increase in energy
demand for the foreseeable future.  We believe that these factors will contribute to robust demand for oil and gas.

The  existing  supply  of  oil  and  gas  is  depleting  and  requires  replenishment.    The  replacement  of  reserves  remains
critically important given the significant underinvestment during the last several years and the challenges to new exploration
and production investments imposed on many industry participants by investors and the governments of oil and gas producing
nations.  Additionally, energy security will remain an important geopolitical factor across Europe, the U.S. and elsewhere with
the growing understanding that hydrocarbons are not easily displaced by alternatives for much of the world’s energy needs.

With  deepwater  and  harsh  environment  fields  generating  favorable  economic  returns  and  relatively  lower  carbon
intensity than other hydrocarbon sources, we expect a significant portion of the required spending in fossil fuel development
will continue to be allocated to deepwater and harsh environment projects.  Although the price for oil may continue to exhibit
volatility in response to several factors outside of our control, including uncertainty about future output from the major oil and
gas producing countries, interest rate changes, geopolitical events and global economic growth, we nevertheless expect prices to
remain at levels that are robustly supportive of investment in deepwater and harsh environment exploration and development
projects.

Significantly reduced offshore contracting activity during the previous downcycle has also resulted in a much smaller
marketable global fleet of floating rigs available to meet the current upcycle in expected customer demands, specifically with
respect  to  the  highest  specification  drilling  units  preferred  by  many  of  our  customers  for  their  projects.    In  recent  quarters,
marketable  supply  and  demand  for  deepwater  and  harsh  environment  rigs  has  become  more  balanced.    Customers  are  now
planning further into the future to ensure availability of rigs for their drilling programs and are signing contracts with longer
lead times and durations, as well as higher dayrates.  Our customers continue to pursue offshore projects in deepwater and harsh
environments  where  rates  of  return  and  production  volumes  are  anticipated  to  be  very  attractive,  which  is  reflected  in  the
resumption of postponed projects, commencement of new drilling and exploration campaigns and extensions of current drilling
campaigns.

Offshore drilling activity remains robust in every major ultra-deepwater geographic sector.  Several new exploration
and  development  programs  have  commenced  as  our  customers  return  their  focus  to  reserve  replacement.    Consequently,
tendering activity improved meaningfully during 2023 and several multi-year tenders and direct negotiations for work in Brazil,
West Africa, North America and Australia were awarded.  Many tenders remain active and are expected to be awarded in the
first half of 2024.

South  America,  the  Gulf  of  Mexico  and,  increasingly,  Africa  are  key  ultra-deepwater  market  sectors.    In  the  last
two years, we observed sustained increases in dayrates for projects in the U.S. Gulf of Mexico and Brazil.  We continue to see
these trends expand to other deepwater sectors.

In Norway, the largest market for harsh environment rigs, we anticipate demand will accelerate and extend through at
least 2027, primarily due to previously enacted Norwegian tax incentive programs.  Several rigs have departed the region to
work in other emerging harsh environment regions that require high-specification, high-efficiency semisubmersibles.  Contract
durations, including subsequent extensions, on most of these units could make them unavailable to relocate for the foreseeable
future.    We  believe  that  these  and  other  factors  affecting  supply  and  demand  for  drilling  rigs  are  likely  to  have  a  favorable
influence on dayrates and contracting terms as competition increases for high-specification, high-efficiency semisubmersibles.

As we project that this increased demand for both our asset groups will be sustained in the coming years, and as there
are  now  fewer  high-specification  offshore  drilling  rigs  capable  of  operating  in  these  markets,  we  believe  this  demand  may
prompt the reactivation of cold-stacked rigs and the delivery of remaining stranded newbuild assets.

As of February 14, 2024, our contract backlog was $9.01 billion compared to $9.40 billion as of October 18, 2023.
 The risks of drilling project delays, contract renegotiations and contract terminations and cancellations remain low as oil prices
have stayed at levels that are supportive of investment in deepwater and harsh environment projects.

Fleet status—We refer to the availability of our rigs in terms of the uncommitted fleet rate.  The uncommitted fleet
rate is defined as the number of uncommitted days divided by the total number of rig calendar days in the measurement period,
expressed  as  a  percentage.   An  uncommitted  day  is  defined  as  a  calendar  day  during  which  a  rig  is  idle  or  stacked,  is  not
contracted to a customer and is not committed to a shipyard.  The uncommitted fleet rates exclude the effect of priced options.
 As of February 14, 2024, our uncommitted fleet rates for each of the five years in the period ending December 31, 2028 were as
follows:

PERFORMANCE AND OTHER KEY INDICATORS

Contract backlog—We believe our industry leading contract backlog sets us apart from the competition and provides
indicators  of  our  future  revenue-earning  opportunities.    Contract  backlog  is  defined  as  the  maximum  contractual  operating
dayrate  multiplied  by  the  number  of  days  remaining  in  the  firm  contract  period,  excluding  revenues  for  mobilization,
demobilization,  contract  preparation,  other  incentive  provisions  or  reimbursement  revenues,  which  are  not  expected  to  be
significant to our contract drilling revenues.  The contract backlog represents the maximum contract drilling revenues that can
be earned considering the contractual operating dayrate in effect during the firm contract period.  The contract backlog for our
fleet was as follows:

Our  contract  backlog  includes  only  firm  commitments,  including  amounts  associated  with  our  contracted  newbuild
units under construction, which are represented by signed drilling contracts or, in some cases, by other definitive agreements
awaiting contract execution.  It does not include conditional agreements and options to extend firm commitments.

The  average  contractual  dayrate  relative  to  our  contract  backlog  is  defined  as  the  average  maximum  contractual
operating dayrate to be earned per operating day in the measurement period.  An operating day is defined as a day for which a
rig  is  contracted  to  earn  a  dayrate  during  the  firm  contract  period  after  operations  commence.    At  February  14,  2024,  the
contract backlog and average contractual dayrates for our fleet were as follows:

The actual amount of revenues earned and the actual periods in which revenues are earned will differ from the amounts
and periods shown in the tables above due to various factors, including shipyard and maintenance projects, unplanned downtime
and  other  factors  that  result  in  lower  applicable  dayrates  than  the  full  contractual  operating  dayrate.   Additional  factors  that
could  affect  the  amount  and  timing  of  actual  revenues  to  be  recognized  include  customer  liquidity  issues  and  contract
terminations that may be available to our customers under certain circumstances.

The contractual operating dayrate may be higher than the actual dayrate we ultimately receive because an alternative
contractual dayrate, such as a waiting-on-weather rate, repair rate, standby rate or force majeure rate, may apply under certain
circumstances.  The contractual operating dayrate may also be higher than the actual dayrate we ultimately receive because of a
number of factors, including rig downtime or suspension of operations.  In certain contracts, the actual dayrate may be reduced
to zero if, for example, repairs extend beyond a stated period of time.  See “Part I. Item 1A. Risk Factors—Risks related to our
business—Our current backlog of contract drilling revenues may not be fully realized.”

Average daily revenue—We believe average daily revenue provides a comparative measurement unit for our revenue-
earning  performance.   Average  daily  revenue  is  defined  as  operating  revenues,  excluding  revenues  for  contract  terminations,
reimbursements and contract intangible amortization, earned per operating day.  The average daily revenue for our fleet was as
follows:

$  382,300   $  345,500

$  355,500
$  386,200
$  365,600

Our  average  daily  revenue  fluctuates  relative  to  market  conditions  and  our  revenue  efficiency.    The  average  daily
revenue  may  be  affected  by  incentive  performance  bonuses  or  penalties  or  demobilization  fee  revenues.    Revenues  for  a
newbuild unit are included in the calculation when the rig commences operations upon acceptance by the customer.  We remove
a rig from the calculation upon disposal or classification as held for sale, unless we continue to operate the rig, in which case we
remove the rig upon completion or novation of the contract.

Revenue efficiency—We believe revenue efficiency measures our ability to ultimately convert our contract backlog
into  revenues.    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.
 The revenue efficiency rates for our fleet were as follows:

Our revenue efficiency rate varies due to revenues earned under alternative contractual dayrates, such as a waiting-on-
weather rate, repair rate, standby rate, force majeure rate or zero rate, that may apply under certain circumstances.  Our revenue
efficiency rate is also affected by incentive performance bonuses or penalties.  We include newbuilds in the calculation when the
rigs  commence  operations  upon  acceptance  by  the  customer.   We  exclude  rigs  that  are  not  operating  under  contract,  such  as
those that are stacked.

Rig  utilization—We  present  our  rig  utilization  as  an  indicator  of  our  ability  to  secure  work  for  our  fleet.    Rig
utilization is defined as the total number of operating days divided by the total number of rig calendar days in the measurement
period, expressed as a percentage.  The rig utilization rates for our fleet were as follows:

Our  rig  utilization  rate  declines  as  a  result  of  idle  and  stacked  rigs  and  during  shipyard,  contract  preparation  and
mobilization  periods.    We  include  newbuilds  in  the  calculation  when  the  rigs  commence  operations  upon  acceptance  by  the
customer.  We remove a rig from the calculation upon disposal or classification as held for sale, unless we continue to operate
the  rig,  in  which  case  we  remove  the  rig  upon  completion  or  novation  of  the  contract.   Accordingly,  our  rig  utilization  can
increase when we remove idle or stacked units from our fleet.

Contract drilling revenues—Contract drilling revenues increased for the year ended December 31, 2023, compared to
the  year  ended  December  31,  2022,  primarily  due  to  the  following:  (a)  approximately  $210  million  resulting  from  higher
average daily revenues, (b) approximately $190 million resulting from the operations of our newbuild ultra-deepwater floaters
Deepwater Atlas and Deepwater Titan placed into service in the two-year period ended December 31, 2023, (c) approximately
$25  million  resulting  from  slightly  improved  efficiency  for  the  fleet,  (d)  approximately  $25  million  resulting  from  higher
reimbursement  revenues  and  (e)  approximately  $10  million  resulting  from  increased  early  termination  revenues.    These
increases were partially offset by the following: (a) approximately $180 million resulting from reduced utilization, primarily for
our  harsh  environment  floaters  that  were  under  mobilization  or  contract  preparation  for  their  next  contract  and
(b) approximately $25 million resulting from cold stacking Deepwater Nautilus.

Costs  and  expenses—Operating  and  maintenance  costs  and  expenses  increased  for  the  year  ended  December  31,
2023, compared to the year ended December 31, 2022, primarily due to the following: (a) approximately $140 million resulting
from  reactivation  and  contract  preparation,  (b)  approximately  $85  million  resulting  from  our  two  newbuild  ultra-deepwater
floaters placed into service, (c) approximately $55 million resulting from the effect of inflation on personnel and maintenance
costs, (d) approximately $40 million resulting from various litigation, customs duties and indirect taxes and (e) approximately
$25 million resulting from higher reimbursable costs.  These increases were partially offset by the following: (a) approximately
$35 million resulting from cold stacking Deepwater Nautilus and (b) approximately $15 million resulting from the favorable
effect of currency exchange rates on personnel costs.

Depreciation and amortization expense increased for the year ended December 31, 2023, compared to the year ended
December 31, 2022, primarily due to (a) $48 million of increased depreciation associated with our newbuild ultra-deepwater
floaters  and  other  property  and  equipment  placed  into  service  since  December  2022,  partially  offset  by  (b)  $23  million  of
reduced  depreciation  resulting  from  the  disposal  of  one  rig  and  the  classification  of  two  rigs  as  held  for  sale  and
(c) approximately $12 million of reduced depreciation resulting from assets that had reached the end of their useful lives or had
been retired.

General and administrative costs and expenses increased for the year ended December 31, 2023, compared to the year
ended  December  31,  2022,  primarily  due  to  the  following:  (a)  approximately  $16  million  resulting  from  increased  personnel
costs, partially offset by (c) approximately $8 million resulting from reduced innovation costs and (d) approximately $4 million
resulting from reduced legal and professional fees.

Loss on impairment or disposal of assets—In the year ended December 31, 2023, we recognized a loss associated
with the impairment of two harsh environment floaters, which we determined were impaired at the time we classified them as
held for sale.

In the year ended December 31, 2023, we recognized a loss of $169 million associated with our non-cash contribution
of  Ocean  Rig  Olympia  and  related  assets  in  exchange  for  an  equity  ownership  interest  in  GSR.    In  the  years  ended
December 31, 2023 and

- 31 -

    
 
Table of Contents

2022, we recognized an aggregate net loss of $14 million and $10 million, respectively, associated with the disposal of assets
unrelated to rig sales.

Other income and expense—Interest expense, net of amounts capitalized, increased in the year ended December 31,
2023,  compared  to  the  year  ended  December  31,  2022,  primarily  due  to  the  following:  (a)  $189  million  resulting  from  debt
issued in the two-year period ended December 31, 2023 and (b) $34 million resulting from reduced interest costs capitalized for
our newbuild construction program, partially offset by (c) $113 million resulting from debt repaid as scheduled or early retired
and  (d)  $30  million  resulting  from  the  fair  value  adjustment  of  the  bifurcated  compound  exchange  feature  embedded  in  the
indenture governing the 4.625% Senior Guaranteed Exchangeable Bonds.

In the year ended December 31, 2023, we recognized a net loss on retirement of debt, primarily associated with the
early retirement of $1.38 billion aggregate principal amount of our debt securities.  In the year ended December 31, 2022, we
recognized  a  net  gain  on  the  retirement  of  debt,  primarily  associated  with  the  early  retirement  of  $116  million  aggregate
principal amount of our debt securities in connection with exchange and purchase agreements.

Other income net, increased in the year ended December 31, 2023, compared to the year ended December 31, 2022,
primarily  due  to  the  following:  (a)  an  increased  gain  of  $18  million  resulting  from  net  changes  to  currency  exchange  rates,
(b) increased income of $17 million associated with our dual-activity patent and (c) increased income of $8 million related to
the  non-service  components  of  net  periodic  benefit  income,  partially  offset  by  (e)  a  loss  of  $27  million  associated  with  a
payment  of  cash  or  the  issuance  of  additional  shares  to  certain  holders  that  elected  to  exercise  their  exchanges  rights  for  the
4.00%  Senior  Guaranteed  Exchangeable  Bonds  and  the  4.625%  Senior  Guaranteed  Exchangeable  Bonds  in  the  year  ended
December 31, 2023.

Income tax expense—In the years ended December 31, 2023 and 2022, our effective tax rate was (1.4) percent and
(10.4) percent, respectively, based on loss before income tax expense.  In the years ended December 31, 2023 and 2022, the
aggregate  effect  of  discrete  period  tax  items  was  a  net  tax  benefit  of  $74  million  and  $19  million,  respectively.    In  the  year
ended December 31, 2023, such discrete items included settlements and expirations of various uncertain tax positions, changes
to valuation allowances and changes to deferred taxes due to new rig operations.  In the year ended December 31, 2022, such
discrete  items  included  settlement  and  expiration  of  various  uncertain  tax  positions,  changes  to  valuation  allowances,
operational  restructuring  and  gains  due  to  exchange  rate  changes.    In  the  years  ended  December  31,  2023  and  2022,  our
effective tax rate, excluding discrete items, was (13.3) percent and (13.6) percent, respectively, based on loss before income tax
expense.  In the year ended December 31, 2023 compared to the year ended December 31, 2022, our effective tax rate increased
primarily due to changes in the relative blend of income from operations in certain jurisdictions.

Due  to  our  operating  activities  and  organizational  structure,  our  income  tax  expense  does  not  change  proportionally
with our income before income taxes.  Significant decreases in our income before income taxes typically lead to higher effective
tax rates, while significant increases in income before income taxes can lead to lower effective tax rates, subject to the other
factors  impacting  income  tax  expense  noted  above.    With  respect  to  the  effective  tax  rate  calculation  for  the  year  ended
December  31,  2023,  a  significant  portion  of  our  income  tax  expense  was  generated  in  countries  in  which  income  taxes  are
imposed  or  treated  to  be  imposed  on  gross  revenues,  with  the  most  significant  of  these  countries  being  Angola  and  India.
 Conversely, the countries in which we incurred the most significant income taxes during this period that were based on income
before income tax include the U.S., Hungary, Brazil, Cyprus, Australia, Norway and Switzerland.  Our rig operating structures
further complicate our tax calculations, especially in instances where we have more than one operating structure for the taxing
jurisdiction and, thus, more than one method of calculating taxes depending on the operating structure utilized by the rig under
the contract.

LIQUIDITY AND CAPITAL RESOURCES

Sources and uses of cash

In the year ended December 31, 2023, our primary sources of cash were net cash proceeds from issuance of debt and

net cash provided by our operating activities.  Our primary uses of cash were debt repayments and capital expenditures.

Net  cash  provided  by  financing  activities  increased  primarily  due  to  (a)  net  cash  proceeds  from  the  issuance  of
$1.175  billion  aggregate  principal  amount  of  8.75%  Senior  Secured  Notes,  $525  million  aggregate  principal  amount  of
8.375% Senior Secured Notes and $325 million aggregate principal amount of 8.00% Senior Secured Notes in the year ended
December 31, 2023, and (b) decreased cash used to repay debt in scheduled installments, partially offset by (c) early repayments
of $1.38 billion aggregate principal amount of certain of our debt securities in the year ended December 31, 2023 compared to
early repayments of $77 million aggregate principal amount in the prior year.

Sources and uses of liquidity

Overview—We  expect  to  use  existing  unrestricted  cash  balances,  cash  flows  from  operating  activities,  borrowings
under our Secured Credit Facility or proceeds from the disposal of assets or the issuance of debt or shares to fulfill anticipated
near-term obligations, which may include capital expenditures, working capital and other operational requirements, scheduled
debt maturities or other payments.  At December 31, 2023, we had $762 million in unrestricted cash and cash equivalents and
$233  million  in  restricted  cash  and  cash  equivalents.    We  have  generated  positive  cash  flows  from  operating  activities  over
recent years and, although we cannot provide assurances, we expect that such cash flows will continue to be positive over the
next year.  For example, among other factors, if we incur costs for reactivation or contract preparation of multiple rigs or to
otherwise assure the marketability of our fleet or general economic, financial, industry or business conditions deteriorate, our
cash flows from operations may be reduced or negative.

Additionally, we have a bank credit agreement for a credit facility, secured by, among other things, a lien on nine of
our  ultra-deepwater  floaters  and  two  of  our  harsh  environment  floaters  (as  amended  from  time  to  time,  the  “Secured  Credit
Facility”).  Our Secured Credit Facility provides us with a borrowing capacity of $600 million through its scheduled maturity on
June  22,  2025,  and  contains  restrictive  covenants,  including  a  minimum  guarantee  coverage  ratio  of  3.0  to  1.0,  a  minimum
collateral  coverage  ratio  of  2.1  to  1.0  and  a  minimum  liquidity  requirement  of  $500  million,  among  others.    For  more
information about the restrictions in our Secured Credit Facility and maturity triggers thereof, as well as on our scheduled debt
maturities in 2024 and beyond, see Notes to Consolidated Financial Statements—Note 9—Debt.

Although we currently anticipate relying on these sources of liquidity, including cash flows from operating activities
and  borrowings  under  our  Secured  Credit  Facility,  among  others,  we  may  in  the  future  consider  establishing  additional
financing arrangements with banks or other capital providers, including shipyard loans, and subject to market conditions and
other factors, we may be required to provide collateral for any such future financing arrangements.  Additionally, we have from
time  to  time  relied  on  issuances  of  equity  or  equity-linked  securities.    For  more  information  about  our  issuances  of  equity
securities, see Notes to Consolidated Financial Statements—Note 9—Debt and Notes to Consolidated Financial Statements—
Note 14—Equity.

Debt  and  equity  markets—From  time  to  time,  we  seek  to  access  the  capital  markets,  including  with  respect  to
potential  liability  management  transactions.    For  example,  during  the  three-year  period  ended  December  31,  2023,  we
completed  multiple  debt  and  equity  transactions,  including  the  redemption,  exchanges  and  retirement  of  existing  debt,  in
connection with our ongoing efforts to prudently manage our capital structure and improve our liquidity position.  Subject to
then-existing market conditions and our expected liquidity needs, among other factors, we may use existing unrestricted cash
balances,  our  cash  flows  from  operating  activities,  or  proceeds  from  asset  sales  to  pursue  liability  management  transactions,
including among others, purchasing or exchanging any of our debt or equity-linked securities in

Table of Contents

the  open  market,  in  privately  negotiated  transactions,  or  through  tender  or  exchange  offers,  or  by  redeeming  any  of  our
outstanding debt securities pursuant to the terms of the applicable governing document, if applicable.  Any future purchases,
exchanges or other transactions may be on the same terms or on terms that are more or less favorable to holders than the terms
of any prior transaction.  We can provide no assurance as to which, if any, of these alternatives, or combinations thereof, we
may choose to pursue in the future, if at all, or as to the timing with respect to any future transactions.  For more information
about our previous debt repayment, redemption and retirement transactions during the three-year period ended December 31,
2023, see Notes to Consolidated Financial Statements—Note 9—Debt.

Our ability and willingness to access the debt and equity markets is a function of a variety of factors, including, among
others, general economic, industry or market conditions, market perceptions of us and our industry and credit rating agencies’
views of our debt.  General economic or market conditions could have an adverse effect on our business and financial position
and  on  the  business  and  financial  position  of  our  customers,  suppliers  and  lenders  and  could  affect  our  ability  to  access  the
capital  markets  on  acceptable  terms  or  at  all  and  our  future  need  or  ability  to  borrow  under  our  Secured  Credit  Facility.    In
addition  to  our  potential  sources  of  funding,  the  effects  of  such  global  events  could  impact  our  liquidity  or  need  to  alter  our
allocation or sources of capital, implement further cost reduction measures and change our financial strategy.  Additionally, the
rating of our long-term debt is below investment grade, which is causing us to experience increased fees and interest rates under
our Secured Credit Facility and indentures governing certain of our senior notes.  Future downgrades may further restrict our
ability to access the debt market for sources of capital and may negatively impact the cost of such capital at a time when we
would like, or need, to access such markets, which could have an impact on our flexibility to react to changing economic and
business conditions.

Drilling  fleet—From  time  to  time,  we  review  possible  acquisitions  of  businesses  and  drilling  rigs,  as  well  as
noncontrolling  ownership  interests  in  other  companies,  and  we  may  make  significant  future  capital  commitments  for  such
purposes.   We  may  also  consider  investments  related  to  major  rig  upgrades,  new  rig  construction,  or  the  acquisition  of  a  rig
under construction.  Any such acquisition or investment could involve the payment by us of a substantial amount of cash or the
issuance of a substantial number of additional shares or other securities.  Our failure to subsequently secure drilling contracts in
these instances, if not already secured, could have an adverse effect on our results of operations or cash flows.

In  the  years  ended  December  31,  2023  and  2022,  we  made  capital  expenditures  of  $427  million  and  $717  million,
respectively, including $331 million and $669 million, respectively, for our newbuild construction projects.  The historical and
projected capital expenditures and non-cash capital additions for our ongoing newbuild construction projects were as follows:

In  September  2023,  we  acquired  Deepwater  Aquila,  an  ultra-deepwater  drillship  under  construction  for  Liquila,  a  previously
unconsolidated  variable  interest  entity,  by  acquiring  the  outstanding  ownership  interests  in  Liquila.    The  seventh  generation,  high-
specification drillship is designed to be equipped with our patented dual activity, a 1,400 short-ton hookload, large deck space, high load
capacities and will be dual-stack ready.  The rig is expected to commence operations under its drilling contract in mid-2024.

In  May  2023,  we  completed  construction  of  the  ultra-deepwater  drillship  Deepwater  Titan,  and  it  commenced  operations  under  its
drilling contract.  Deepwater Titan is equipped with two 20,000 pounds per square inch blowout preventers and other equipment required
by our customer.

In October 2022, we completed construction of the ultra-deepwater drillship Deepwater Atlas, and it commenced the first of two phases
of  operations  using  a  15,000  pounds  per  square  inch  blowout  preventer.    In  October  2023,  the  rig  completed  installation  of  a
20,000 pounds per square inch blowout preventer and related equipment, and is expected to return to service in the first half of 2024.

The ultimate amount of our capital expenditures is partly dependent upon financial market conditions, the actual level
of  operational  and  contracting  activity,  the  costs  associated  with  the  current  regulatory  environment  and  customer  requested
capital improvements and equipment for which the customer agrees to reimburse us.  As with any major shipyard project that
takes place over an extended period of time, the actual costs, the timing of expenditures and the project completion date may
vary  from  estimates  based  on  numerous  factors,  including  actual  contract  terms,  weather,  exchange  rates,  shipyard  labor
conditions, availability of suppliers to recertify equipment and the market demand for components and resources required for
drilling unit construction.  We intend to fund the cash requirements for our projected capital expenditures by using available
cash  balances,  cash  generated  from  operations  and  asset  sales,  borrowings  under  our  Secured  Credit  Facility  and  financing
arrangements  with  banks  or  other  capital  providers.    Economic  conditions  and  other  factors  could  impact  the  availability  of
these sources of funding.  See “—Sources and uses of liquidity.”

From  time  to  time,  we  may  also  review  the  possible  disposition  of  certain  drilling  assets.    During  the  year  ended
December  31,  2023,  we  made  a  non-cash  contribution  of  an  ultra-deepwater  floater,  together  with  related  assets  and  a  cash
contribution of $10 million, as consideration for an equity ownership interest in an unconsolidated affiliate.  Additionally, on
February  15,  2024,  we  completed  the  sale  of  two  harsh  environment  floaters.    Considering  market  conditions,  we  have
previously committed to plans to sell certain lower specification

- 34 -

 
 
 
  
  
 
Table of Contents

drilling units for scrap value, and we may identify additional lower-specification drilling units to be sold for scrap, recycling or
alternative purposes.  See Notes to Consolidated Financial Statements—Note 7—Long-Lived Assets.

Contractual obligations—We provide additional information about our cash requirements for known contractual and

other obligations on both a short-term and long-term basis in the notes to our consolidated financial statements as follows:

◾ For  additional  information  regarding  our  operating  and  finance  lease  obligations,  see  Notes  to  Consolidated  Financial

Statements—Note 8—Leases.

◾ For  additional  information  regarding  our  debt  obligations  and  scheduled  maturities,  see  Notes  to  Consolidated  Financial

Statements—Note 9—Debt.

◾ For  additional  information  regarding  the  obligations  to  our  employees  under  our  various  postemployment  benefit  plans,  see

Notes to Consolidated Financial Statements—Note 10—Postemployment Benefit Plans.

◾ For additional information regarding our tax obligations, see Notes to Consolidated Financial Statements—Note 11—Income

Taxes.

◾ For  additional  information  regarding  our  obligations  under  long-term  purchase  agreements  and  service  agreements  and  our

material contingencies, see Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies.

Other  commercial  commitments—We  have  other  commercial  commitments,  such  as  standby  letters  of  credit  and
surety bonds that guarantee our performance as it relates to our drilling contracts, insurance, customs, tax and other obligations
in various jurisdictions.  The cash obligations of these commitments, which are primarily geographically concentrated in Brazil,
are not normally called because we typically comply with the underlying performance requirements.  Standby letters of credit
are  issued  under  various  committed  and  uncommitted  credit  lines,  some  of  which  require  cash  collateral.    For  additional
information regarding our standby letters of credit and surety bond guarantees, see Notes to Consolidated Financial Statements
—Note 13—Commitments and Contingencies.

RELATED PARTY TRANSACTIONS

In  April  2023,  Perestroika  AS  (together  with  its  subsidiaries,  “Perestroika”),  an  entity  affiliated  with  one  of  our
directors that beneficially owns approximately 11 percent of our shares, exchanged $213 million aggregate principal amount of
the 2.50% Senior Guaranteed Exchangeable Bonds under the terms of the governing indenture at the applicable exchange rate
of  162.1626  Transocean  Ltd.  shares  per  $1,000  note.    As  part  of  the  transaction  governing  the  exchange,  we  delivered
34.6  million  Transocean  Ltd.  shares  and  additional  immaterial  cash  consideration  to  such  exchanging  holder.   The  director’s
beneficial  ownership  of  our  shares  resulting  from  these  transactions  did  not  change.    See  Notes  to  Consolidated  Financial
Statements—Note 9—Debt.

In  September  2023,  we  issued  11.9  million  Transocean  Ltd.  shares  with  an  aggregate  value  of  $99  million,  which
included  2.0  million  Transocean  Ltd.  shares  with  an  aggregate  value  of  $16.4  million  issued  to  Perestroika,  to  acquire  the
outstanding  ownership  interests  in  Liquila,  and  as  a  result,  Liquila  became  our  wholly  owned  subsidiary.    See  Notes  to
Consolidated Financial Statements—Note 4—Unconsolidated Affiliates.

We engage in certain related party transactions with our unconsolidated affiliates.  Our most significant transactions
with  our  unconsolidated  affiliates  are  under  agreements  with  Orion  Holdings  (Cayman)  Limited  as  follows:  (a)  we  operate,
stack  and  maintain  Transocean  Norge  under  a  management  services  agreement,  (b)  we  market  Transocean  Norge  under  a
marketing  services  agreement  and  (c)  during  operations,  we  lease  Transocean  Norge  under  a  bareboat  charter  agreement.
 Additionally,  we  procure  and  provide  services  and  equipment  from  and  to  other  unconsolidated  affiliates  for  technological
innovation  and  subsea  minerals  exploration.    See  Notes  to  Consolidated  Financial  Statements—Note  4—Unconsolidated
Affiliates.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Overview

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the
U.S., which require us to make estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related
disclosures of contingent assets and liabilities.  These estimates require significant judgments and assumptions.  We evaluate our
estimates on an ongoing basis using historical experience and various other assumptions that we believe are reasonable under
the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities
that are not readily apparent from other sources.  Actual results may differ from these estimates.

We  consider  the  following  to  be  our  critical  accounting  policies  and  estimates  since  they  are  very  important  to  the
portrayal of our financial condition and results and require our most subjective and complex judgments.  We have discussed the
development, selection and disclosure of such policies and estimates with the audit committee of our board of directors.  For
information  about  our  significant  accounting  policies  and  accounting  standards  updates,  see  Notes  to  Consolidated  Financial
Statements—Note 2—Significant Accounting Policies.

Income taxes

Overview—We  provide  for  income  taxes  based  on  expected  taxable  income,  statutory  rates  and  tax  laws  in  the
jurisdictions  in  which  we  operate  or  have  a  taxable  presence.    The  relationship  between  our  provision  for  or  benefit  from
income taxes and our income or loss before income taxes can vary significantly from period to period considering, among other
factors, (a) the overall level of income before income taxes, (b) changes in the blend of income that is taxed based on gross
revenues rather than income before taxes, (c) rig movements

- 35 -

Table of Contents

between  taxing  jurisdictions  and  (d)  our  rig  operating  structures.    Consequently,  our  income  tax  expense  does  not  change
proportionally with our income or loss before income taxes.

Uncertain tax positions—We apply significant judgment to evaluate our tax positions based on the interpretation of
tax laws in various jurisdictions and with the use of estimates and assumptions regarding significant future events, such as the
amount, timing and character of income, deductions and tax credits.  Our tax liability in any given year could be affected by
changes  in  tax  laws,  regulations,  agreements,  and  treaties,  currency  exchange  restrictions  or  our  level  or  profitability  of
operations  in  each  jurisdiction.    The  tax  laws  relating  to  the  offshore  drilling  industry  in  certain  jurisdictions  in  which  we
operate are not well developed, requiring us to apply incremental judgment.  Although we employ the best information available
at  the  time  we  prepare  our  annual  tax  provision,  a  number  of  years  may  elapse  before  the  tax  liabilities  in  the  various
jurisdictions are ultimately determined.

We are undergoing examinations of our tax returns in a number of taxing jurisdictions for various years.  We review
our  liabilities  on  an  ongoing  basis  and,  to  the  extent  audits  or  other  events  cause  us  to  adjust  the  liabilities  accrued  in  prior
periods, we recognize those adjustments in the period of the event.  Our tax liabilities are dependent on numerous factors that
cannot be reasonably projected, including among others, the amount and nature of additional taxes potentially asserted by local
tax  authorities;  the  willingness  of  local  tax  authorities  to  negotiate  a  fair  settlement  through  an  administrative  process;  the
impartiality  of  the  local  courts;  and  the  potential  for  changes  in  the  taxes  paid  to  one  country  that  either  produce,  or  fail  to
produce, offsetting tax changes in other countries.  Consequently, we cannot reasonably estimate the future impact of changes to
the assumptions and estimates related to our annual tax provision.

Unrecognized  tax  benefits—We  establish  liabilities  for  estimated  tax  exposures,  and  the  provisions  and  benefits
resulting  from  changes  to  those  liabilities  are  included  in  our  annual  tax  provision  along  with  related  interest  and  penalties.
  Such  tax  exposures  include  potential  challenges  to  intercompany  pricing,  disposition  transactions,  and  withholding  tax  rates
and their applicability.  These exposures may be affected by changes in applicable tax law or other factors, which could cause us
to  revise  our  prior  estimates,  and  are  generally  resolved  through  the  settlement  of  audits  within  these  tax  jurisdictions  or  by
judicial  means.    At  December  31,  2023  and  2022,  we  had  unrecognized  tax  benefits  of  $458  million  and  $471  million,
respectively, including interest and penalties, against which we recorded net operating loss deferred tax assets of $411 million
and $383 million, respectively, resulting in net unrecognized tax benefits of $47 million and $88 million, respectively, including
interest and penalties, that upon reversal would favorably impact our effective tax rate.

Valuation allowance—We  apply  significant  judgment  to  determine  whether  our  deferred  tax  assets  will  be  fully  or
partially realized.  Our evaluation requires us to consider all available positive and negative evidence, including projected future
taxable  income  and  the  existence  of  cumulative  losses  in  recent  years.    We  continually  evaluate  opportunities  for  the  future
utilization of our deferred tax assets.  When it is estimated to be more likely than not that all or some portion of certain deferred
tax assets, such as foreign tax credit carryovers or net operating loss carryforwards, will not be realized, we establish a valuation
allowance for the amount of the deferred tax assets that is considered to be unrealizable.  During the years ended December 31,
2023 and 2022, in connection with our evaluation of the projected realizability of our deferred tax assets, we determined that
our consolidated cumulative loss incurred over the recent three-year period has limited our ability to consider other subjective
evidence, such as projected contract activity rather than contract backlog.  See Notes to Consolidated Financial Statements—
Note 11—Income Taxes.

Property and equipment

Overview—We apply significant judgment to account for our property and equipment, consisting primarily of offshore
drilling rigs and related equipment, related to estimates and assumptions for cost capitalization, useful lives and salvage values.
 At December 31, 2023 and 2022, the carrying amount of our property and equipment was $16.94 billion and $17.47 billion,
respectively, representing 84 percent and 85 percent, respectively, of our total assets.

Capitalized costs—We capitalize costs incurred to enhance, improve and extend the useful lives of our property and
equipment  and  expense  costs  incurred  to  repair  and  maintain  the  existing  condition  of  our  rigs.    For  newbuild  construction
projects, we also capitalize the initial preparation, mobilization and commissioning costs incurred until the drilling unit is placed
into  service.    Cost  capitalization  affects  our  results  of  operations  by  reducing  expenses  in  the  period  incurred  and  increasing
depreciation expense over the useful life of the asset.

Useful lives and salvage values—We depreciate our assets using the straight-line method over their estimated useful
lives after allowing for salvage values.  We estimate useful lives and salvage values by applying judgments and assumptions
that  reflect  both  historical  experience  and  expectations  regarding  future  operations,  rig  utilization  and  asset  performance.
 Useful lives and salvage values of rigs are difficult to estimate due to a variety of factors, including (a) technological advances
that impact the methods or cost of oil and gas exploration and development, (b) changes in market or economic conditions and
(c) changes in laws or regulations affecting the drilling industry.  Applying different judgments and assumptions in establishing
the useful lives and salvage values would likely result in materially different net carrying amounts and depreciation expense for
our  assets.    We  reevaluate  the  remaining  useful  lives  and  salvage  values  of  our  rigs  when  certain  events  occur  that  directly
impact the useful lives and salvage values of the rigs, including changes in operating condition, functional capability and market
and economic factors.  We may also consider major capital upgrades required to perform certain contracts and the long-term
impact of those upgrades on future marketability.  At December 31, 2023, a hypothetical one-year increase in the useful lives of
all of our rigs would cause a decrease in our annual depreciation expense of approximately $33 million and a hypothetical one-
year decrease would cause an increase in our annual depreciation expense of approximately $13 million.

Table of Contents

Long-lived  asset  impairment—We  review  our  property  and  equipment  for  impairment  when  events  or  changes  in
circumstances  indicate  that  the  carrying  amounts  of  our  assets  held  and  used  may  not  be  recoverable.    Potential  impairment
indicators  include  rapid  declines  in  commodity  prices  and  related  market  conditions,  declines  in  dayrates  or  utilization,
cancellations of contracts or credit concerns of multiple customers.  During periods of oversupply, we may idle or stack rigs for
extended periods of time or we may elect to sell certain rigs for scrap, which could be an indication that an asset group may be
impaired since supply and demand are the key drivers of rig utilization and our ability to contract our rigs at economical rates.
 Our rigs are mobile units, equipped to operate in geographic regions throughout the world and, consequently, we may mobilize
rigs from an oversupplied region to a more lucrative and undersupplied region when it is economical to do so.  Many of our
contracts generally allow our customers to relocate our rigs from one geographic region to another, subject to certain conditions,
and our customers utilize this capability to meet their worldwide drilling requirements.  Accordingly, our rigs are considered to
be interchangeable within classes or asset groups, and we evaluate impairment by asset group.  We consider our asset groups to
be ultra-deepwater floaters and harsh environment floaters.

We  assess  recoverability  of  assets  held  and  used  by  projecting  undiscounted  cash  flows  for  the  asset  group  being
evaluated.  When the carrying amount of the asset group is determined to be unrecoverable, we recognize an impairment loss,
measured as the amount by which the carrying amount of the asset group exceeds its estimated fair value.  To estimate the fair
value of each asset group, we apply a variety of valuation methods, incorporating income, market and cost approaches.  We may
weigh the approaches, under certain circumstances, when relevant data is limited, when results are inconclusive or when results
deviate significantly.  Our estimate of fair value generally requires us to use significant unobservable inputs, representative of
Level 3 fair value measurements, including assumptions related to the long-term future performance of our asset groups, such as
projected revenues and costs, dayrates, rig utilization and revenue efficiency.  These projections involve uncertainties that rely
on assumptions about demand for our services, future market conditions and technological developments.  Because our business
is  cyclical  in  nature,  the  results  of  our  impairment  testing  are  expected  to  vary  significantly  depending  on  the  timing  of  the
assessment  relative  to  the  business  cycle.   Altering  either  the  timing  of  or  the  assumptions  used  to  estimate  fair  value  and
significant  unanticipated  changes  to  the  assumptions  could  materially  alter  an  outcome  that  could  otherwise  result  in  an
impairment loss.  Given the nature of these evaluations and their application to specific asset groups and specific time periods, it
is  not  possible  to  reasonably  quantify  the  impact  of  changes  in  these  assumptions.    See  Notes  to  Consolidated  Financial
Statements—Note 7—Long-Lived Assets.

OTHER MATTERS

Regulatory matters

We occasionally receive inquiries from governmental regulatory agencies regarding our operations around the world,
including  inquiries  with  respect  to  various  tax,  environmental,  regulatory  and  compliance  matters.   To  the  extent  appropriate
under the circumstances, we investigate such matters, respond to such inquiries and cooperate with the regulatory agencies.  See
Notes to Consolidated Financial Statements—Note 13—Commitments and Contingencies.

Tax matters

We conduct operations through our various subsidiaries in countries throughout the world.  Each country has its own
tax  regimes  with  varying  statutory  rates,  deductions  and  tax  attributes,  which  are  subject  to  changes  resulting  from  new
legislation, interpretation or guidance.  From time to time, as a result of these changes, we may revise previously evaluated tax
positions,  which  could  cause  us  to  adjust  our  recorded  tax  assets  and  liabilities.    Tax  authorities  in  certain  jurisdictions  are
examining  our  tax  returns  and,  in  some  cases,  have  issued  assessments.    We  intend  to  defend  our  tax  positions  vigorously.
 Although we can provide no assurance as to the outcome of the aforementioned changes, examinations or assessments, we do
not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial position or results of
operations;  however,  it  could  have  a  material  adverse  effect  on  our  consolidated  statement  of  cash  flows.    See  Notes  to
Consolidated Financial Statements—Note 11—Income Taxes.

ITEM 7A.QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Overview—We  are  exposed  to  interest  rate  risk,  primarily  associated  with  our  long-term  debt,  including  current
maturities.    Additionally,  we  are  exposed  to  equity  price  risk  related  to  certain  of  our  exchangeable  bonds  and  currency
exchange rate risk related to our international operations.

Interest  rate  risk—The  following  table  presents  the  scheduled  installment  amounts  and  related  weighted-average
interest rates of our long-term debt instruments by contractual maturity date.  The expected maturity amounts, presented below,
include both principal and other installments.  The following table presents information as of December 31, 2023, for each of
the five years in the period ending December 31, 2028 and thereafter (in millions, except interest rate percentages):

At  December  31,  2023  and  2022,  the  fair  value  of  our  outstanding  debt  was  $7.31  billion  and  $6.41  billion,
respectively.    During  the  year  ended  December  31,  2023,  the  fair  value  of  our  debt  increased  by  $896  million  due  to  the
following:  (a)  an  increase  of  $2.05  billion  due  to  the  issuance  of  the  8.375%  senior  secured  notes  due  February  2028,
8.00% senior secured notes due September 2028 and the 8.75% senior secured notes due February 2030, (b) a net increase of
$817  million  resulting  from  changes  in  the  market  prices  of  our  outstanding  debt,  partially  offset  by  (c)  a  decrease  of
$1.36 billion due to early retirement of certain notes, (d) a decrease of $380 million due to the exchange of the 2.50% senior
guaranteed exchangeable bonds due January 2027 and partial exchanges of the 4.00% senior guaranteed exchangeable bonds
due  December  2025  and  the  4.625%  senior  guaranteed  exchangeable  bonds  due  September  2029  (the  “4.625%  Senior
Guaranteed Exchangeable Bonds”) and (e) a decrease of $225 million due to scheduled installments.  See Notes to Consolidated
Financial Statements—Note 9—Debt and Notes to Consolidated Financial Statements—Note 19—Risk Concentration.

The  majority  of  our  cash  equivalents  is  subject  to  variable  interest  rates  or  short-term  interest  rates  and  such  cash

equivalents earn commensurately higher rates of return when interest rates increase.

Equity price risk—We are exposed to equity price risk primarily related to the bifurcated compound exchange feature
contained  within  the  4.625%  Senior  Guaranteed  Exchangeable  Bonds.    The  compound  exchange  feature  must  be  bifurcated
from the host debt instrument since it is not considered indexed to our stock.  The market price of our shares is the primary
driver of the fair value of the exchange feature.  At December 31, 2023, the fair value of the bifurcated compound exchange
feature  was  $350  million.   At  December  31,  2023,  a  10  percent  hypothetical  increase  or  decrease  to  the  market  price  of  our
shares  would  result  in  a  $43  million  increase  or  decrease  in  the  carrying  amount  of  the  exchange  feature,  recorded  as  a
component of our debt, and a corresponding adjustment to interest expense.  See Notes to Consolidated Financial Statements—
Note 9—Debt and Notes to Consolidated Financial Statements—Note 19—Risk Concentration.

Currency exchange rate risk—We are exposed to currency exchange rate risk primarily related to contract drilling
revenues,  employee  compensation  costs  and  purchasing  costs  that  are  denominated  in  currencies  other  than  our  functional
currency, the U.S. dollar.  We use a variety of techniques to minimize the exposure to currency exchange rate risk, including the
structuring of customer contract payment terms and occasional use of forward exchange contracts.  Our primary tool to manage
currency  exchange  rate  risk  involves  structuring  customer  contracts  to  provide  for  payment  in  both  U.S.  dollars  and  local
currency.    The  payment  portion  denominated  in  local  currency  is  based  on  anticipated  local  currency  requirements  over  the
contract term.  Due to various factors, including customer acceptance, local banking laws, national content requirements, other
statutory  requirements,  local  currency  convertibility,  local  inflation  and  revenue  efficiency,  actual  local  currency  needs  may
vary from those realized in the customer contracts, resulting in partial exposure to currency exchange rate risk.  The currency
exchange effect resulting from our international operations generally has not had a material impact on our operating results.  See
Notes to Consolidated Financial Statements—Note 19—Risk Concentration.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

Management’s Report on Internal Control Over Financial Reporting

Management of Transocean Ltd. (the “Company,” “we” or “our”) is responsible for the integrity and objectivity of the
financial information included in this annual report.  We have prepared our financial statements in accordance with accounting
principles  generally  accepted  in  the  United  States,  which  require  us  to  apply  our  best  judgement  to  make  estimates  and
assumptions  for  certain  amounts.    We  are  responsible  for  establishing  and  maintaining  a  system  of  internal  controls  and
procedures  to  provide  reasonable  assurance  regarding  the  reliability  of  financial  reporting  and  the  preparation  of  the
consolidated  financial  statements.    Our  internal  control  system  is  supported  by  a  program  of  internal  audits  and  appropriate
reviews  by  management,  written  policies  and  guidelines,  careful  selection  of  qualified  personnel,  and  a  written  Code  of
Integrity.  Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements
and,  even  when  determined  to  be  effective,  can  only  provide  reasonable  assurance  with  respect  to  financial  statement
preparation and presentation.  Also, projections of any evaluation of effectiveness in future periods are subject to the risk that
controls  may  become  inadequate  because  of  changes  in  conditions,  or  that  the  degree  of  compliance  with  the  policies  or
procedures may deteriorate.

Management of the Company is responsible for establishing and maintaining adequate internal control over financial
reporting as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934.  Management assessed the
effectiveness of the Company’s internal control over financial reporting as of December 31, 2023.  In making this assessment,
management  used  the  criteria  set  forth  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission,  as
described in Internal  Control-Integrated  Framework,  as  published  in  2013.    Based  on  this  assessment,  management  believes
that the Company maintained effective internal control over financial reporting as of December 31, 2023.

The Company’s independent auditors, Ernst & Young LLP, a registered public accounting firm, are appointed by the
audit  committee  of  the  Company’s  board  of  directors,  subject  to  ratification  by  our  shareholders.    Ernst  &  Young  LLP  has
audited and reported on the consolidated financial statements of Transocean Ltd. and subsidiaries, and the Company’s internal
control over financial reporting.  The reports of the independent auditors are contained in this annual report.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Transocean Ltd.

Opinion on Internal Control Over Financial Reporting

We have audited Transocean Ltd. and subsidiaries’ internal control over financial reporting as of December 31, 2023, based on
criteria  established  in  Internal  Control—Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the
Treadway Commission (2013 framework) (the COSO criteria).  In our opinion, Transocean Ltd. and subsidiaries (the Company)
maintained, in all material respects, effective internal control over financial reporting as of December 31, 2023, based on the
COSO criteria.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)
(PCAOB),  the  consolidated  balance  sheets  of  the  Company  as  of  December  31,  2023  and  2022,  the  related  consolidated
statements  of  operations,  comprehensive  loss,  equity  and  cash  flows  for  each  of  the  three  years  in  the  period  ended
December 31, 2023, and the related notes and financial statement schedule listed in the Index at Item 15(a) and our report dated
February 20, 2024 expressed an unqualified opinion thereon.

Basis for Opinion

The  Company’s  management  is  responsible  for  maintaining  effective  internal  control  over  financial  reporting  and  for  its
assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report
on Internal Control Over Financial Reporting.  Our responsibility is to express an opinion on the Company’s internal control
over financial reporting based on our audit.  We are a public accounting firm registered with the PCAOB and are required to be
independent  with  respect  to  the  Company  in  accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and
regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the
audit  to  obtain  reasonable  assurance  about  whether  effective  internal  control  over  financial  reporting  was  maintained  in  all
material respects.

Our  audit  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk  that  a  material
weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and
performing  such  other  procedures  as  we  considered  necessary  in  the  circumstances.    We  believe  that  our  audit  provides  a
reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A  company’s  internal  control  over  financial  reporting  is  a  process  designed  to  provide  reasonable  assurance  regarding  the
reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally
accepted accounting principles.  A company’s internal control over financial reporting includes those policies and procedures
that  (1)  pertain  to  the  maintenance  of  records  that,  in  reasonable  detail,  accurately  and  fairly  reflect  the  transactions  and
dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit
preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting  principles,  and  that  receipts  and
expenditures  of  the  company  are  being  made  only  in  accordance  with  authorizations  of  management  and  directors  of  the
company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely  detection  of  unauthorized  acquisition,  use,  or
disposition of the company’s assets that could have a material effect on the financial statements.

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements.   Also,
projections  of  any  evaluation  of  effectiveness  to  future  periods  are  subject  to  the  risk  that  controls  may  become  inadequate
because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Report of Independent Registered Public Accounting Firm

To the Shareholders and the Board of Directors of Transocean Ltd.

Opinion on the Financial Statements

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Transocean  Ltd.  and  subsidiaries  (the  Company)  as  of
December 31, 2023 and 2022, the related consolidated statements of operations, comprehensive loss, equity and cash flows for
each of the three years in the period ended December 31, 2023, and the related notes and financial statement schedule listed in
the Index at Item 15(a) (collectively referred to as the “consolidated financial statements”).  In our opinion, the consolidated
financial  statements  present  fairly,  in  all  material  respects,  the  financial  position  of  the  Company  at  December  31,  2023  and
2022, and the results of its operations and its cash flows for each of the three years in the period ended December 31, 2023, in
conformity with U.S. generally accepted accounting principles.

We  also  have  audited,  in  accordance  with  the  standards  of  the  Public  Company  Accounting  Oversight  Board  (United  States)
(PCAOB),  the  Company's  internal  control  over  financial  reporting  as  of  December  31,  2023,  based  on  criteria  established  in
Internal  Control-Integrated  Framework  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission
(2013 framework), and our report dated February 20, 2024, expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company's management.  Our responsibility is to express an opinion on
the Company’s financial statements based on our audits.  We are a public accounting firm registered with the PCAOB and are
required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable
rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB.  Those standards require that we plan and perform the
audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to
error  or  fraud.    Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the  financial
statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.    Such  procedures  included
examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements.  Our audits also included
evaluating  the  accounting  principles  used  and  significant  estimates  made  by  management,  as  well  as  evaluating  the  overall
presentation of the financial statements.  We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the financial statements that
were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that
are  material  to  the  financial  statements  and  (2)  involved  our  especially  challenging,  subjective  or  complex  judgments.    The
communication of the critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken
as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit
matters or on the accounts or disclosures to which they relate.

Description of the
Matter

Income Taxes

As  discussed  in  Notes  2  and  11  to  the  consolidated  financial  statements,  the  Company  operates  in
multiple  jurisdictions  through  a  complex  operating  structure  and  is  subject  to  applicable  tax  laws,
treaties  or  regulations  in  each  jurisdiction  where  it  operates.    The  Company’s  provision  for  income
taxes is based on the tax laws and rates applicable in each jurisdiction.  The Company recognizes tax
benefits  they  believe  are  more  likely  than  not  to  be  sustained  upon  examination  by  the  taxing
authorities based on the technical merits of the position.

Auditing management’s provision for income taxes and related deferred taxes was complex because of
the  Company’s  multi-national  operating  structure.    In  addition,  a  higher  degree  of  auditor  judgment
was  required  to  evaluate  the  Company’s  deferred  tax  provision  as  a  result  of  the  Company’s
interpretation of tax law in certain jurisdictions across its multiple subsidiaries.

- 41 -

Table of Contents

How We Addressed
the Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls
over  the  Company’s  income  tax  provision  process,  including  controls  over  management’s  review  of
the identification and valuation of deferred income taxes and changes in tax laws and regulations that
may impact the Company’s deferred income tax provision.

Our  audit  procedures  also  included,  among  others,  (i)  obtaining  an  understanding  of  the  Company’s
overall tax structure, evaluating changes in the Company’s tax structure that occurred during the year
as  well  as  changes  in  tax  law,  and  assessing  the  interpretation  of  those  changes  under  the  relevant
jurisdiction’s  tax  law;  (ii)  utilizing  tax  resources  with  appropriate  knowledge  of  local  jurisdictional
laws  and  regulations;  (iii)  evaluating  the  completeness  and  accuracy  of  deferred  income  taxes,  and
(iv)  assessing  the  reasonableness  of  the  Company’s  valuation  allowance  on  deferred  tax  assets,
including  projections  of  taxable  income  from  the  future  reversal  of  existing  taxable  temporary
differences.

Loss on Disposal of Ocean Rig Olympia

As discussed in Notes 4 and 7 to the consolidated financial statements, the Company made a non-cash
contribution of the ultra-deepwater floater Ocean Rig Olympia, and related assets, with an estimated
fair value of $85 million, in exchange for a noncontrolling ownership interest in Global Sea Mineral
Resources  NV.    As  a  result,  the  Company  recognized  a  loss  of  $169  million,  associated  with  the
disposal of the rig and related assets for the year ended December 31, 2023.

Auditing  management’s  estimate  of  the  fair  value  of  Ocean  Rig  Olympia  and  related  assets  was
complex  and  judgmental  due  to  the  estimation  required  in  determining  the  fair  value  of
Ocean  Rig  Olympia.    In  particular,  the  fair  value  estimate  of  Ocean  Rig  Olympia  was  sensitive  to
significant assumptions such as the discount rate, rig utilization, revenue efficiency and dayrates.

Description of the
Matter

How We Addressed
the Matter in Our
Audit

We obtained an understanding, evaluated the design and tested the operating effectiveness of controls
over the Company’s process to determine the fair value of the rig and related loss on disposal of assets
calculation,  including  controls  over  management’s  review  of  the  significant  assumptions  described
above as well as over the underlying data used in the fair value and related loss determination.

To test the estimated fair value of Ocean Rig Olympia we performed audit procedures that included,
among  others,  (i)  assessing  the  valuation  methodologies  utilized  by  management;  (ii)  testing  the
significant assumptions discussed above; (iii) testing the completeness and accuracy of the underlying
data used by the Company in its analysis; and (iv) testing the mathematical accuracy of the fair value
and related loss on disposal of assets calculations.  We involved a valuation specialist to assist in our
evaluation  of  the  Company's  model,  valuation  methodology  and  significant  assumptions.    We
reviewed for contrary evidence related to the determination of the fair value of the rig and related loss
on disposal of assets, including reviewing relevant market data and internal Company forecasts.

NOTE 1—BUSINESS

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Transocean Ltd. (together with its subsidiaries and predecessors, unless the context requires otherwise, “Transocean,”
“we,”  “us”  or  “our”)  is  a  leading  international  provider  of  offshore  contract  drilling  services  for  oil  and  gas  wells.    As  of
December 31, 2023, we owned or had partial ownership interests in and operated a fleet of 37 mobile offshore drilling units,
consisting of 28 ultra-deepwater floaters and nine harsh environment floaters.  As of December 31, 2023, we were constructing
one ultra-deepwater drillship.

We  provide,  as  our  primary  business,  contract  drilling  services  in  a  single  operating  segment,  which  involves
contracting  our  mobile  offshore  drilling  rigs,  related  equipment  and  work  crews  to  drill  oil  and  gas  wells.   We  specialize  in
technically  demanding  regions  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 used in support of offshore drilling activities and offshore support services on a worldwide basis.

We  perform  contract  drilling  services  by  deploying  our  high-specification  fleet  in  a  single,  global  market  that  is
geographically dispersed in oil and gas exploration and development areas throughout the world.  The location of our rigs and
the allocation of our resources to build or upgrade rigs are determined by the activities and needs of our customers.

NOTE 2—SIGNIFICANT ACCOUNTING POLICIES

Accounting estimates—To prepare financial statements in accordance with accounting principles generally accepted
in the United States (“U.S.”), we must make judgments by applying estimates and assumptions that affect the reported amounts
of assets, liabilities, revenues and expenses and the disclosures of contingent assets and liabilities.  On an ongoing basis, we
evaluate  our  estimates  and  assumptions,  including  those  related  to  our  income  taxes,  property  and  equipment,  equity
investments,  contingencies,  allowance  for  excess  materials  and  supplies,  assets  held  for  sale,  intangibles,  postemployment
benefit plans and share-based compensation.  We base our estimates and assumptions on historical experience and other factors
that we believe are reasonable.  Actual results could differ from such estimates.

Fair value measurements—We estimate fair value at an exchange price that would be received to sell an asset or paid
to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between
market participants.  Our valuation techniques require inputs that we categorize using a three-level hierarchy, from highest to
lowest level of observable inputs, as follows: (1) significant observable inputs, including unadjusted quoted prices for identical
assets or liabilities in active markets (“Level 1”), (2) significant other observable inputs, including direct or indirect market data
for  similar  assets  or  liabilities  in  active  markets  or  identical  assets  or  liabilities  in  less  active  markets  (“Level  2”)  and
(3) significant unobservable inputs, including those that require considerable judgment for which there is little or no market data
(“Level 3”).  When a valuation requires multiple input levels, we categorize the entire fair value measurement according to the
lowest level of input that is significant to the measurement even though we may have also utilized significant inputs that are
more readily observable.

Consolidation—We consolidate entities in which we have a majority voting interest and entities that meet the criteria
for  variable  interest  entities  for  which  we  are  deemed  to  be  the  primary  beneficiary  for  accounting  purposes.    We  eliminate
intercompany transactions and accounts in consolidation.  We apply the equity method of accounting for an equity investment in
an unconsolidated entity if we have the ability to exercise significant influence over the entity that (a) does not meet the variable
interest  entity  criteria  or  (b)  meets  the  variable  interest  entity  criteria,  but  for  which  we  are  not  deemed  to  be  the  primary
beneficiary.  We measure other equity investments at fair value if the investment has a fair value that is readily determinable;
otherwise, we measure the investment at cost, less any impairment.  We separately present within equity on our consolidated
balance sheets the ownership interests attributable to parties with noncontrolling interests in our consolidated subsidiaries, and
we  separately  present  net  income  attributable  to  such  parties  on  our  consolidated  statements  of  operations.    See  Note  4—
Unconsolidated Affiliates and Note 14—Equity.

Functional currency—We  consider  the  U.S.  dollar  to  be  the  functional  currency  for  all  of  our  operations  since  the
majority of our revenues and expenditures are denominated in U.S. dollars, which limits our exposure to currency exchange rate
fluctuations.  We recognize currency exchange rate gains and losses in other, net.  In the years ended December 31, 2023, 2022
and 2021, we recognized a net gain of $10 million, a net loss of $8 million and a net loss of $1 million, respectively, related to
currency exchange rates.

Revenues  and  related  pre-operating  costs—We  recognize  revenues  earned  under  our  drilling  contracts  based  on
variable dayrates, which range from a full operating dayrate to lower rates or zero rates for periods when drilling operations are
interrupted or restricted, based on the specific activities we perform during the contract on an hourly, or more frequent, basis.
 Such dayrate consideration is attributed to the distinct time period to which it relates within the contract term, and therefore, is
recognized as we perform the services.  When the operating dayrate declines over the contract term, we recognize revenues on a
straight-line basis over the estimated contract period.  We recognize reimbursement revenues and the corresponding costs as we
provide  the  customer-requested  goods  and  services,  when  such  reimbursable  costs  are  incurred  while  performing  drilling
operations.    Prior  to  performing  drilling  operations,  we  may  receive  pre-operating  revenues,  on  either  a  fixed  lump-sum  or
variable  dayrate  basis,  for  mobilization,  contract  preparation,  customer-requested  goods  and  services  or  capital  upgrades,  for
which we record a contract liability and recognize as revenues on a straight-line basis over the estimated contract period.  We
recognize losses for loss contracts as such losses are incurred.  We recognize revenues for demobilization

- 48 -

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

over  the  contract  period  unless  otherwise  constrained.    We  recognize  revenues  from  contract  terminations  as  we  fulfill  our
obligations and all contingencies have been resolved.  We apply the optional exemption that permits us to exclude disclosure of
the estimated transaction price related to the variable portion of unsatisfied performance obligations at the end of the reporting
period, as our transaction price is typically based on a single performance obligation consisting of a series of distinct hourly, or
more frequent, periods, the variability of which will be resolved at the time of the future services.

To obtain contracts with our customers, we incur pre-operating costs to prepare a rig for contract and mobilize a rig to
the drilling location.  We defer such pre-operating contract preparation and mobilization costs for recognition in operating and
maintenance costs over the estimated contract period on a straight-line basis, consistent with the general pace of activity.  See
Note 5—Revenues.

Income taxes—We  provide  for  income  taxes  based  on  expected  taxable  income,  statutory  rates  and  tax  laws  in  the
jurisdictions in which we operate or have a taxable presence.  We recognize the effect of changes in tax laws as of the date of
enactment.  We recognize potential global intangible low-taxed income inclusions as a period cost.

We maintain liabilities for estimated tax exposures in our jurisdictions of operation, and we recognize the provisions
and  benefits  resulting  from  changes  to  those  liabilities  in  our  income  tax  expense  or  benefit  along  with  related  interest  and
penalties.  Income tax exposure items include potential challenges to permanent establishment positions, intercompany pricing,
disposition transactions, and withholding tax rates and their applicability.  These tax exposures are resolved primarily through
the settlement of audits within these tax jurisdictions or by judicial means, but can also be affected by changes in applicable tax
law or other factors, which could cause us to revise past estimates.

We measure deferred tax assets and liabilities using enacted tax rates that will apply in the years in which the deferred
tax  assets  and  liabilities  are  expected  to  be  recovered  or  paid.    In  evaluating  our  ability  to  realize  deferred  tax  assets,  we
consider all available positive and negative evidence, including projected future taxable income and the existence of cumulative
losses in recent years.  We record a valuation allowance for deferred tax assets when it is more likely than not that some or all of
the benefit from the deferred tax asset will not be realized.  For example, we may record a valuation allowance for deferred tax
assets resulting from net operating losses incurred during the year in certain jurisdictions for which the benefit of the losses will
not be realized or for foreign tax credit carryforwards that may expire prior to their utilization.  See Note 11—Income Taxes.

Cash  and  cash  equivalents—We  consider  cash  equivalents  to  include  highly  liquid  debt  instruments  with  original
maturities of three months or less, such as time deposits with commercial banks that have high credit ratings, U.S. Treasury and
government securities, Eurodollar time deposits, certificates of deposit and commercial paper.  We may also invest excess funds
in  no-load,  open-ended,  management  investment  trusts.    Such  management  trusts  invest  exclusively  in  high-quality  money
market instruments.

Restricted cash and cash equivalents—We maintain restricted cash and cash equivalents that are either pledged for
debt  service  under  certain  bond  indentures,  as  required  under  certain  bank  credit  arrangements,  or  held  in  accounts  that  are
subject  to  restrictions  due  to  legislation,  regulation  or  court  order.    We  classify  such  restricted  cash  and  cash  equivalents  in
current assets if the restriction is expected to expire or otherwise be resolved within one year or if such funds are considered to
offset liabilities that are properly classified as current liabilities. See Note 9—Debt.

Materials and supplies—We record materials and supplies at their average cost less an allowance for excess items.
 We estimate the allowance for excess items based on historical experience and expectations for future use of the materials and
supplies.  At December 31, 2023 and 2022, our allowance for excess items was $198 million and $199 million, respectively.

Property  and  equipment—We  apply  judgment  to  account  for  our  property  and  equipment,  consisting  primarily  of
offshore  drilling  rigs  and  related  equipment,  related  to  estimates  and  assumptions  for  cost  capitalization,  useful  lives  and
salvage  values.    We  base  our  estimates  and  assumptions  on  historical  experience  and  expectations  regarding  future  industry
conditions and operations.  At December 31, 2023, the aggregate carrying amount of our property and equipment represented
approximately 84 percent of our total assets.

We capitalize expenditures for newbuilds, renewals, replacements and improvements, including capitalized interest, if
applicable, and we recognize the expense for maintenance and repair costs as incurred.  For newbuild construction projects, we
also  capitalize  the  initial  preparation,  mobilization  and  commissioning  costs  incurred  until  the  drilling  unit  is  placed  into
service.  Upon sale or other disposition of an asset, we recognize a net gain or loss on disposal of the asset, which is measured
as the difference between the net carrying amount of the asset and the net proceeds received.  We compute depreciation using
the straight-line method after allowing for salvage values.

The estimated original useful life of our drilling units is 35 years, our buildings and improvements range from three to
30 years and our machinery and equipment range from four to 20 years.  We reevaluate the remaining useful lives and salvage
values  of  our  rigs  when  certain  events  occur  that  directly  impact  the  useful  lives  and  salvage  values  of  the  rigs,  including
changes in operating condition, functional capability and market and economic factors.  When evaluating the remaining useful
lives of rigs, we also consider major capital upgrades required to perform certain contracts and the long-term impact of those
upgrades on future marketability.

Long-lived  asset  impairment—We  review  the  carrying  amounts  of  long-lived  assets,  including  property  and
equipment and right-of-use assets, for potential impairment when events occur or circumstances change that indicate that the
carrying amount of such assets may not be recoverable.  For assets classified as held and used, we determine recoverability by
evaluating the estimated undiscounted future net cash flows based on projected dayrates and utilization of the asset group under
review.  We consider our asset groups to be

- 49 -

Table of Contents

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

ultra-deepwater floaters and harsh environment floaters.  When an impairment of one or more of our asset groups is indicated,
we measure an impairment as the amount by which the carrying amount of the asset group exceeds its estimated fair value.  We
measure the fair values of our asset groups by applying a variety of valuation methods, incorporating a combination of income,
market and cost approaches, using projected discounted cash flows and estimates of the exchange price that would be received
for the assets in the principal or most advantageous market for the assets in an orderly transaction between market participants
as  of  the  measurement  date.    For  an  asset  classified  as  held  for  sale,  we  consider  the  asset  to  be  impaired  to  the  extent  its
carrying amount exceeds its estimated fair value less cost to sell.  See Note 7—Long-Lived Assets.

Equity investments and impairment—We review our equity-method investments, and other equity investments for
which  a  readily  determinable  fair  value  is  not  available,  for  potential  impairment  when  events  or  changes  in  circumstances
indicate  that  the  carrying  amount  of  the  investment  might  not  be  recoverable  in  the  near  term.    If  we  determine  that  an
impairment that is other than temporary exists, we recognize an impairment loss, measured as the amount by which the carrying
amount  of  the  investment  exceeds  its  estimated  fair  value.   To  estimate  the  fair  value  of  the  investment,  we  apply  valuation
methods  that  rely  primarily  on  the  income  and  market  approaches.    In  the  years  ended  December  31,  2023  and  2021,  we
recognized  a  loss  of  $5  million  and  $37  million,  respectively,  associated  with  the  other-than-temporary  impairment  of  the
carrying amount of our equity investments.  We amortize the basis difference caused by such impairments using the straight-line
method over the estimated life of the asset.  See Note 4—Unconsolidated Affiliates.

Pension  and  other  postemployment  benefit  plans—We  use  a  measurement  date  of  January  1  for  determining  net
periodic  benefit  costs  and  December  31  for  determining  plan  benefit  obligations  and  the  fair  values  of  plan  assets.    We
determine  our  net  periodic  benefit  costs  based  on  a  market-related  value  of  assets  that  reduces  year-to-year  volatility  by
including  investment  gains  or  losses  subject  to  amortization  over  a  five-year  period  from  the  year  in  which  they  occur.   We
calculate investment gains or losses for this purpose as the difference between the expected return calculated using the market-
related value of assets and the actual return based on the market-related value of assets.  If gains or losses exceed 10 percent of
the greater of plan assets or plan liabilities, we amortize such gains or losses over the average expected future service period of
the employee participants.

We  measure  the  actuarially  determined  obligations  and  related  costs  for  our  defined  benefit  pension  and  other
postemployment  benefit  plans,  retiree  life  insurance  and  medical  benefits,  by  applying  assumptions,  the  most  significant  of
which include long-term rate of return on plan assets, discount rates and mortality rates.  For the long-term rate of return, we
develop our assumptions regarding the expected rate of return on plan assets based on historical experience and projected long-
term investment returns, and we weight the assumptions based on each plan’s asset allocation.  For the discount rate, we base
our assumptions on a yield curve approach using Aa-rated corporate bonds and the expected timing of future benefit payments.
 At  December  31,  2023  and  2022,  the  funded  status  of  our  pension  and  other  postemployment  benefit  plans  represented  an
aggregate  liability  of  $125  million  and  $174  million,  respectively,  and  an  aggregate  asset  of  $31  million  and  $44  million,
respectively.  See Note 10—Postemployment Benefit Plans.

Share-based compensation—To measure the fair values of granted or modified service-based restricted share units,
we use the market price of our shares on the grant date or modification date.  To measure the fair values of granted or modified
performance-based restricted share units subject to market factors, we use an average price at the performance start date and
project  performance  based  on  a  Monte  Carlo  simulation  model  under  a  risk-neutral  approach  and  apply  assumptions  for  the
expected life, risk-free interest rate, expected volatility and dividend yield.  To measure the fair values of granted or modified
performance-based restricted share units that are subject to performance targets, we use the market price of our shares on the
grant date or modification date and adjust the value for the projected performance rate expected to be achieved at the end of the
measurement  period.    We  recognize  share-based  compensation  expense  in  the  same  financial  statement  line  item  as  cash
compensation  paid  to  the  respective  employees  or  non-employee  directors.    We  recognize  such  compensation  expense  on  a
straight-line  basis  over  the  service  period  through  the  date  the  employee  or  non-employee  director  is  no  longer  required  to
provide service to earn the award.  See Note 15—ShareBased Compensation.

Contingencies—We assess our contingencies on an ongoing basis to evaluate the appropriateness of our liabilities and
disclosures for such contingencies.  We establish liabilities for estimated loss contingencies when we believe a loss is probable
and  the  amount  of  the  probable  loss  can  be  reasonably  estimated.    Once  established,  we  adjust  the  carrying  amount  of  a
contingent  liability  upon  the  occurrence  of  a  recognizable  event  when  facts  and  circumstances  change,  altering  our  previous
assumptions with respect to the likelihood or amount of loss.  We recognize corresponding assets for those loss contingencies
that we believe are probable of being recovered through insurance.  We recognize expense for legal costs as they are incurred,
and  we  recognize  a  corresponding  asset  for  such  legal  costs  only  if  we  expect  such  legal  costs  to  be  recovered  through
insurance.

NOTE 3—ACCOUNTING STANDARDS UPDATE

operating  decision-maker.    The  update,  which  permits  early  adoption,  is  effective  for  annual  periods  beginning  after
December 15, 2023 and must be applied retrospectively to all periods presented, unless impracticable.  We continue to evaluate
the requirements and do not expect our adoption to have a material effect on our consolidated statements of financial position,
operations or cash flows or on the disclosures contained in our notes to consolidated financial statements.

Income taxes—Effective no later than January 1, 2025, we will adopt the accounting standards update that requires
significant  additional  disclosures  intended  to  enhance  the  transparency  and  decision-usefulness  of  income  tax  disclosures,
particularly  in  the  rate  reconciliation  table  and  disclosures  about  income  taxes  paid.    The  new  guidance  will  be  applied
prospectively  and  permits,  but  does  not  require,  retrospective  application.    The  update,  which  permits  early  adoption,  is
effective  for  annual  periods  beginning  after  December  15,  2024.    We  continue  to  evaluate  the  requirements.   Although  we
expect our adoption will require us to augment certain disclosures in our notes to consolidated financial statements, we do not
expect our adoption to have a material effect on our consolidated statements of financial position, operations or cash flows.

NOTE 4—UNCONSOLIDATED AFFILIATES

Equity investments

Overview—At December 31, 2023, we hold equity investments in certain unconsolidated companies, including (a) our
16 percent ownership interest in Global Sea Mineral Resources NV (together with its subsidiaries, “GSR”), a Belgian company
and  leading  developer  of  nodule  collection  technology,  which  is  engaged  in  the  development  and  exploration  of  deep-sea
polymetallic nodules that contain metals critical to the growing renewable energy market, (b) our 33 percent ownership interest
in Orion Holdings (Cayman) Limited (together with its subsidiary, “Orion”), a Cayman Islands company that owns the harsh
environment  floater  Transocean  Norge,  (c)  our  19  percent  ownership  interest  in  Ocean  Minerals  LLC  (together  with  its
subsidiaries,  “Ocean  Minerals”),  the  parent  company  of  Moana  Minerals  Ltd.,  a  Cook  Islands  subsea  resource  development
company  that  intends  to  explore  and  collect  polymetallic  nodules,  (d)  our  22  percent  ownership  interest  in  Nauticus
Robotics,  Inc.,  a  publicly  traded  company  that  develops  highly  sophisticated,  ultra-sustainable  marine  robots  and  intelligent
software to power them, and (e) our ownership interests in other companies involved in researching and developing technology
to improve efficiency, reliability, sustainability and safety for drilling and other activities.

In  the  years  ended  December  31,  2023,  2022  and  2021,  we  recognized  a  net  loss  of  $14  million,  $24  million  and
$10 million, respectively, recorded in other income and expense, associated with equity in losses of our equity investments.  At
December  31,  2023  and  2022,  the  aggregate  carrying  amount  of  our  equity  investments  was  $216  million  and  $113  million,
respectively, recorded in other assets.

Contributions—In  February  2023,  we  made  a  cash  contribution  of  $10  million  and  a  non-cash  contribution  of  the
ultra-deepwater floater Ocean Rig Olympia,  which  had  been  cold  stacked,  and  related  assets,  with  an  estimated  fair  value  of
$85 million (see Note  7—Long-Lived  Assets),  in  exchange  for  an  equity  ownership  interest  in  GSR.    We  estimated  the  fair
value  of  the  rig  using  projected  discounted  cash  flows,  and  our  estimate  required  us  to  use  significant  unobservable  inputs,
representative of Level 3 fair value measurements, including assumptions related to the future performance of the rig, projected
demand  for  its  services,  rig  availability  and  dayrates.    In  the  year  ended  December  31,  2022,  we  made  an  aggregate  cash
contribution of $42 million for partial equity ownerships in various companies, including among others, our initial investments
in Liquila Ventures Ltd. (together with its subsidiaries, “Liquila”) and Ocean Minerals.

Impairments—In the years ended December 31, 2023 and 2021, we recognized a loss of $5 million and $37 million,
respectively, which had no tax effect, recorded in other, net, associated with the impairment of certain equity investments upon
determination  that  the  carrying  amount  exceeded  the  estimated  fair  value  and  that  the  impairment  was  other  than  temporary.
  For  the  impairment  in  the  year  ended  December  31,  2021,  we  estimated  the  fair  value  of  our  investment  by  applying  the
income method using significant unobservable inputs, representative of Level 3 fair value measurements, including an assumed
discount rate of 12 percent and assumptions about the future performance of the investment, such as future demand and supply
for harsh environment floaters, rig utilization, revenue efficiency and dayrates.

Related party transactions

Operating activities—We  engage  in  certain  related  party  transactions  with  our  unconsolidated  affiliates.    Our  most
significant transactions with our unconsolidated affiliates are under agreements with Orion as follows: (a) we operate, stack and
maintain  Transocean  Norge  under  a  management  services  agreement,  (b)  we  market  Transocean  Norge  under  a  marketing
services agreement and (c) during operations, we lease Transocean Norge under a bareboat charter agreement.  Additionally, we
procure and provide services and equipment from and to other unconsolidated affiliates for technological innovation and subsea
minerals exploration.

In the years ended December 31, 2023, 2022 and 2021, we incurred costs of approximately $55 million, $54 million
and $24 million, respectively, for Transocean Norge, primarily for contract preparation and upgrade shipyard costs, which are
reimbursable  from  Orion,  the  owner  of  the  rig.    In  the  years  ended  December  31,  2023,  2022  and  2021,  we  received  an
aggregate  cash  payment  of  $49  million,  $40  million  and  $16  million,  respectively,  for  services  and  equipment  provided  to
Orion.  Additionally, in the year ended December 31, 2023, we and Orion agreed to the non-cash net settlement of a balance of
$25 million of accounts receivable and payable.  In the years ended December 31, 2023, 2022 and 2021, we recognized rent
expense of $26 million, $11 million and $12 million, respectively, recorded in

- 51 -

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

operating  and  maintenance  costs,  and  made  an  aggregate  cash  payment  of  $27  million,  $10  million  and  $15  million,
respectively, to charter the rig and rent other equipment from Orion.

In the years ended December 31, 2023, 2022 and 2021, we made an aggregate cash payment of $12 million, $7 million
and  $6  million,  respectively,  to  other  unconsolidated  affiliates  for  research  and  development  and  for  equipment  to  reduce
emissions and improve reliability.  At December 31, 2023 and 2022, our accounts receivable from affiliates was $14 million and
$32 million, respectively, recorded in other current assets, and our accounts payable to affiliates was $4 million and $2 million,
respectively, recorded in accounts payable.

Acquisition—In  November  2022,  we  and  Perestroika  AS  (together  with  its  subsidiaries,  “Perestroika”),  an  entity
affiliated with one of our directors that beneficially owns approximately 11 percent of our shares, each made a cash contribution
of $15 million and $10 million, respectively, to Liquila, a previously unconsolidated variable interest entity, that is constructing
the  ultra-deepwater  floater  Deepwater  Aquila.    Together  with  a  contribution  from  the  holder  of  the  remaining  67  percent
ownership interest, these contributions were used to make the initial payment to the shipyard to acquire the newbuild drillship
for a purchase price of approximately $200 million.  At December 31, 2022, the aggregate carrying amount of our investment in
Liquila was $15 million, recorded in other assets.  On September 15, 2023, we issued 11.9 million Transocean Ltd. shares with
an aggregate value of $99 million, which included 2.0 million Transocean Ltd. shares with an aggregate value of $16.4 million
issued  to  Perestroika,  to  acquire  the  outstanding  ownership  interests  in  Liquila,  and  as  a  result,  Liquila  became  our  wholly
owned subsidiary.  See Note 7—Long Lived Assets and Note 14—Equity.

Debt investments—We  occasionally  invest  in  debt  instruments  of  our  unconsolidated  affiliates.    In  June  2021,  we
made  a  cash  investment  of  $33  million  in  a  $100  million  financing  arrangement  for  Orion  to  refinance  its  shipyard  loans.
 Borrowings under the financing arrangement were secured by Transocean Norge, and outstanding borrowings incurred interest
at the London Interbank Offered Rate plus a margin of 6.50 percent per annum.  At December 31, 2022, the aggregate carrying
amount  of  our  investment  in  the  financing  arrangement  was  $37  million,  recorded  in  other  assets.    In  September  2023,  we
agreed  to  exchange  the  borrowings  under  the  financing  arrangement  for  an  additional  equity  investment  in  Orion,  and  Orion
subsequently entered into a new credit facility with another lender.  At December 31, 2023 and 2022, the aggregate principal
amount due to us under the various financing arrangements with our unconsolidated affiliates was $6 million and $41 million,
respectively, recorded in other assets.

NOTE 5—REVENUES

Overview—We  earn  revenues  primarily  by  performing  the  following  activities:  (i)  providing  our  drilling  rig,  work
crews,  related  equipment  and  services  necessary  to  operate  the  rig  (ii)  delivering  the  drilling  rig  by  mobilizing  to  and
demobilizing from the drill location, and (iii) performing certain pre-operating activities, including rig preparation activities or
equipment modifications required for the contract.  These services represent a single performance obligation under most of our
drilling contracts with customers that is satisfied over time, the duration of which varies by contract.  At December 31, 2023, the
drilling contract with the longest expected remaining duration, excluding unexercised options, extends through July 2029.

Disaggregation—Our  contract  drilling  revenues,  disaggregated  by  asset  group  and  by  country  in  which  they  were

earned, were as follows (in millions):

(a) The aggregate carrying amount of long-lived assets located in other countries that individually represented less than 10 percent

of total long-lived assets.

Because the majority of our assets are mobile, the geographic locations of such assets at the end of the periods are not
necessarily  indicative  of  the  geographic  distribution  of  the  operating  revenues  generated  by  such  assets  during  the  periods
presented.  Our international operations are subject to certain political and other uncertainties, including risks of war and civil
disturbances or other market disrupting events, expropriation of equipment, repatriation of income or capital, taxation policies,
and  the  general  hazards  associated  with  certain  areas  in  which  we  operate.    Although  we  are  organized  under  the  laws  of
Switzerland, we have minimal assets located in Switzerland, and we do not conduct any operations or earn operating revenues
in Switzerland.

In the years ended December 31, 2023, 2022 and 2021, we capitalized interest costs of $39 million, $73 million and

$50 million, respectively, for our construction work in progress.

Acquisition—In  September  2023,  we  acquired  $126  million  of  property  and  equipment  associated  with
Deepwater  Aquila,  an  ultra-deepwater  drillship  under  construction  for  Liquila,  together  with  $7  million  of  cash  and  cash
equivalents, and we assumed $19 million of accounts payable.  See Note 4—Unconsolidated Affiliates and Note 14—Equity.

Disposals—During  the  year  ended  December  31,  2023,  in  connection  with  our  investment  in  a  partial  ownership
interest in GSR, we made a non-cash contribution of the cold-stacked ultra-deepwater floater Ocean Rig Olympia and related
assets.  In the year ended December 31, 2023, we recognized a loss of $169 million ($0.22 per diluted share), which had no tax
effect, associated with the disposal of the rig and related assets (see Note 4—Unconsolidated Affiliates).  During the year ended
December  31,  2021,  in  connection  with  our  efforts  to  dispose  of  non-strategic  assets,  we  completed  the  sale  of  the  harsh
environment floater Leiv Eiriksson and related assets.  In the year ended December 31, 2021, we received net cash proceeds of
$4 million, and recognized an aggregate net loss of $57 million ($0.09 per diluted share), which had no tax effect, associated
with the disposal of the rig and related assets.  In the years ended December 31, 2023, 2022 and 2021, we received aggregate
net cash proceeds of $4 million, $7 million and $5 million, respectively and recognized an aggregate net loss of $14 million,
$10 million and $5 million, respectively, associated with the disposal of assets unrelated to rig sales.

Impairment—In  June  2023,  we  committed  to  the  sale  of  the  harsh  environment  floaters  Paul  B.  Loyd,  Jr.  and
Transocean Leader and related assets for expected aggregate net cash proceeds of $49 million.  In the year ended December 31,
2023, we recognized an aggregate loss of $57 million ($0.07 per diluted share), which had no tax effect, associated with the
impairment of the rigs and related assets, which we determined were impaired at the time that we classified the assets as held
for sale.  We measured the impairment of the rigs and related assets as the amount by which the carrying amount exceeded the
estimated  fair  value  less  costs  to  sell.    We  estimated  the  fair  value  of  the  assets  using  significant  other  observable  inputs,
representative of Level 2 fair value measurements, including a binding contract for the sale of the rigs and related assets.

Assets  held  for  sale—At  December  31,  2023,  the  aggregate  carrying  amount  of  our  assets  held  for  sale,  including

Paul B. Loyd, Jr. and Transocean Leader and related assets, was $49 million, recorded in other current assets.

(f) Transocean Inc. is the issuer of the unregistered notes.  The senior secured notes are fully and unconditionally guaranteed on an unsecured basis

by Transocean Ltd. and on a limited senior secured basis by each of the wholly owned subsidiary owners of the collateral rigs.

Transocean Ltd. and Transocean Inc. are not subject to any significant restrictions on their ability to obtain funds from

their consolidated subsidiaries by dividends, loans or capital distributions.

Indentures—The  indentures  that  govern  our  debt  generally  contain  covenants  that,  among  other  things,  limit  our
ability to incur certain liens on our drilling units without equally and ratably securing the notes, to engage in certain sale and
lease back transactions covering any of our drilling units, to allow our subsidiaries to incur certain additional debt, or to engage
in  certain  merger,  consolidation  or  reorganization  transactions  or  to  enter  into  a  scheme  of  arrangement  qualifying  as  an
amalgamation.

The indentures that govern the 4.00% senior guaranteed exchangeable bonds due December 2025 (the “4.00% Senior
Guaranteed  Exchangeable  Bonds”)  and  the  4.625%  senior  guaranteed  exchangeable  bonds  due  September  2029  (the
“4.625%  Senior  Guaranteed  Exchangeable  Bonds”)  require  such  bonds  to  be  repurchased  upon  the  occurrence  of  certain
fundamental changes and events, at specified prices depending on the particular fundamental change or event, which include
changes  and  events  related  to  certain  (i)  change  of  control  events  applicable  to  Transocean  Ltd.  or  Transocean  Inc.,  (ii)  the
failure of our shares to be listed or quoted on a national securities exchange and (iii) specified tax matters.

The indentures that govern the 6.875% senior secured notes due February 2027, the 8.375% senior secured notes due
February 2028 (the “8.375% Senior Secured Notes”) and the 8.75% senior secured notes due February 2030 (the “8.75% Senior
Secured Notes”) contain covenants that limit the ability of our subsidiaries that own or operate the collateral rigs to declare or
pay dividends to their affiliates.

The indentures that govern our senior secured notes contain certain lien requirements.  At December 31, 2023, we had
restricted  cash  and  cash  equivalents  of  $198  million  deposited  in  restricted  accounts  to  satisfy  debt  service  and  reserve
requirements for the senior secured notes.  At December 31, 2023, the rigs encumbered for the senior secured notes and our
Shipyard  Loans,  including  Deepwater  Aquila,  which  is  under  construction,  Deepwater  Atlas,  Deepwater  Pontus,
Deepwater  Poseidon,  Deepwater  Proteus,  Deepwater  Thalassa,  Deepwater  Titan,  Transocean  Enabler 
and
Transocean Encourage, had an aggregate carrying amount of $6.13 billion.  We will be required to redeem the senior secured
notes at a price equal to 100 percent of the aggregate principal amount without a make-whole premium, upon the occurrence of
certain events related to the respective collateral rigs and related drilling contracts.

Interest  rate  adjustments—At  December  31,  2023,  the  interest  rate  in  effect  for  the  7.35%  senior  notes  due
December 2041 was 9.35 percent, which is subject to adjustment from time to time upon a change to the credit rating of our
non-credit enhanced senior unsecured long-term debt.

Scheduled maturities—At December 31, 2023, the scheduled maturities of our debt, including other installments of

Credit agreements

Secured Credit Facility—As of December 31, 2023, we have a secured revolving credit facility established under a
bank  credit  agreement  (as  amended  from  time  to  time,  the  “Secured  Credit  Facility”),  which  provides  us  with  a  borrowing
capacity of $600 million through its scheduled maturity on June 22, 2025.  We may borrow under the Secured Credit Facility at
a forward looking term rate based on the secured overnight financing rate (“Term SOFR”) plus a margin (the “Secured Credit
Facility  Margin”)  and  a  Term  SOFR  spread  adjustment  of  0.10  percent.   The  Secured  Credit  Facility  is  subject  to  permitted
extensions and certain early maturity triggers, including if on any date the aggregate amount of scheduled principal repayments
of indebtedness, with certain exceptions, due within 91 days thereof is equal to or in excess of $200 million and available cash
is less than $250 million.  The Secured Credit Facility permits us to increase the aggregate amount of commitments by up to
$250  million.    The  Secured  Credit  Facility  is  guaranteed  by  Transocean  Ltd.  and  certain  wholly  owned  subsidiaries.    The
Secured  Credit  Facility  is  secured  by,  among  other  things,  a  lien  on  the  ultra-deepwater  floaters  Deepwater  Asgard,
Deepwater  Corcovado,  Deepwater 
Skyros,

The Secured Credit Facility contains covenants that, among other things, include maintenance of a minimum guarantee
coverage  ratio  of  3.0  to  1.0,  a  minimum  collateral  coverage  ratio  of  2.1  to  1.0,  a  maximum  debt  to  capitalization  ratio  of

and certain of our subsidiaries to, among other things, merge, consolidate or otherwise make changes to the corporate structure,
incur liens, incur additional indebtedness, enter into transactions with affiliates and pay dividends and other distributions.  In
order to utilize the Secured Credit Facility, we must, at the time of the borrowing request, be in full compliance with the terms
and  conditions  of  the  Secured  Credit  Facility  and  make  certain  representations  and  warranties,  including  with  respect  to
compliance with laws and solvency, to the lenders.  Repayment of borrowings under the Secured Credit Facility are subject to
acceleration upon the occurrence of an event of default.  Under the agreements governing certain of our debt and finance lease,
we  are  also  subject  to  various  covenants,  including  restrictions  on  creating  liens,  engaging  in  sale/leaseback  transactions  and
engaging  in  certain  merger,  consolidation  or  reorganization  transactions.    A  default  under  our  public  debt  indentures,  the
agreements governing our senior secured notes, our finance lease contract or any other debt owed to unaffiliated entities that
exceeds $125 million could trigger a default under the Secured Credit Facility and, if not waived by the lenders, could cause us
to lose access to the Secured Credit Facility.  At December 31, 2023, based on the credit rating of the Secured Credit Facility on
that date, the Secured Credit Facility Margin was 2.875 percent and the facility fee was 0.625 percent.  At December 31, 2023,
we  had  no  borrowings  outstanding,  $13  million  of  letters  of  credit  issued,  and  we  had  $587  million  of  available  borrowing
capacity under the Secured Credit Facility.

Shipyard financing arrangement—We have credit agreements that established the Shipyard Loans to finance all or a
portion  of  the  final  payments  owed  to  the  shipyard  upon  delivery  of  the  ultra-deepwater  floaters  Deepwater  Atlas  and
Deepwater Titan.  Borrowings under the Shipyard Loan for Deepwater Atlas are secured by, among other security, a lien on the
rig,  and  borrowings  under  the  Shipyard  Loan  for  Deepwater Titan  are  unsecured.    We  have  the  right  to  prepay  outstanding
borrowings, in full or in part, without penalty.  The Shipyard Loans contain covenants that, among other things, limit the ability
of  the  subsidiary  owners  of  the  drilling  rigs  to  incur  certain  types  of  additional  indebtedness  or  make  certain  additional
commitments or investments.  In June 2022, we borrowed $349 million under the Shipyard Loan for Deepwater Atlas and made
a  cash  payment  of  $46  million  to  satisfy  the  final  milestone  payment  due  upon  delivery  of  the  rig.    In  December  2022,  we
borrowed $90 million under the Shipyard Loan for Deepwater Titan and made a cash payment of $325 million to satisfy the
final milestone payment due upon delivery of the rig.  We recorded each Shipyard Loan, net of imputed interest, with an initial
carrying  amount  of  $300  million  and  $82  million,  respectively,  and  corresponding  non-cash  capital  additions,  recorded  in
property and equipment.  The carrying amount of each Shipyard Loan at inception represented its estimated fair value using
significant other observable inputs, representative of Level 2 fair value measurements, including the terms and credit spreads of
our debt, by applying an estimated discount rate of 9.4 percent and 7.6 percent, respectively.

second business day immediately preceding the maturity date and, at our election, such exchange may be settled by delivering
cash, Transocean Ltd. shares or a combination of cash and shares.  The 4.625% Senior Guaranteed Exchangeable Bonds may be
exchanged by holders at any time prior to the close of business on the second business day immediately preceding the maturity
date  or  redemption  date  and,  at  our  election,  such  exchange  may  be  settled  by  delivering  cash,  Transocean  Ltd.  shares  or  a

The  4.625%  Senior  Guaranteed  Exchangeable  Bonds  contain  a  compound  exchange  feature  that,  in  addition  to  the
exchange terms outlined above, requires us to pay holders a make whole premium of future interest through March 30, 2028, for
exchanges  exercised  during  a  redemption  notice  period.    Such  compound  exchange  feature  must  be  bifurcated  from  the  host
debt  instrument  since  it  is  not  considered  indexed  to  our  stock.   Accordingly,  we  recognize  changes  to  the  liability  for  the
estimated  fair  value  of  the  bifurcated  compound  exchange  feature  with  a  corresponding  adjustment  to  interest  expense.   At
December 31, 2023 and 2022, the carrying amount of the bifurcated compound exchange feature, recorded as a component of
the carrying amount of debt, was $350 million and $295 million, respectively.

Exchanges—In  April  2023,  Perestroika  exchanged  $213  million  aggregate  principal  amount  of  the  2.50%  senior
guaranteed exchangeable bonds due January 2027 (the “2.50% Senior Guaranteed Exchangeable Bonds”) under the terms of the
governing  indenture  at  the  applicable  exchange  rate  of  162.1626  Transocean  Ltd.  shares  per  $1,000  note.    As  part  of  the
transaction  governing  the  exchange,  we  delivered  34.6  million  Transocean  Ltd.  shares  and  additional  immaterial  cash
consideration to such exchanging holder.  The director’s beneficial ownership of our shares resulting from these transactions did
not change.

In  July  2023,  the  holders  of  the  remaining  outstanding  $25  million  aggregate  principal  amount  of  2.50%  Senior
Guaranteed Exchangeable Bonds exchanged such bonds under the terms of the governing indenture at the applicable exchange
rate of 162.1626 Transocean Ltd. shares per $1,000 note.  As part of the transaction, we delivered 4.0 million Transocean Ltd.
shares.

In October 2023, holders of $60 million and $41 million aggregate principal amount of the 4.00% Senior Guaranteed
Exchangeable Bonds and the 4.625% Senior Guaranteed Exchangeable Bonds, respectively, exchanged such bonds under the
terms  of  the  governing  indenture  at  the  applicable  exchange  rate  of  190.4762  and  290.6618  Transocean  Ltd.  shares,
respectively,  per  $1,000  note.    As  part  of  the  transactions,  we  delivered  an  aggregate  26.5  million  Transocean  Ltd.  shares,
including an aggregate 3.1 million additional shares to such holders.

Debt issuance

Senior  secured  notes—In  January  2023,  we  issued  $525  million  aggregate  principal  amount  of  8.375%  Senior
Secured Notes, and we received $516 million aggregate cash proceeds, net of issue costs.  The 8.375% Senior Secured Notes
are secured by the assets and earnings associated with the ultra-deepwater floater Deepwater Titan and the equity of the wholly
owned  subsidiary  that  owns  or  operates  the  collateral  rig.    Additionally,  we  are  required  to  maintain  certain  balances  in  a
restricted  cash  account  to  satisfy  debt  service  requirements.   We  may  redeem  all  or  a  portion  of  the  8.375%  Senior  Secured
Notes  on  or  prior  to  February  1,  2025  at  a  price  equal  to  100  percent  of  the  aggregate  principal  amount  plus  a  make-whole
premium, and subsequently, at specified redemption prices.

In January 2023, we issued $1.175 billion aggregate principal amount of 8.75% Senior Secured Notes, and we received
$1.148 billion aggregate cash proceeds, net of issue costs.  The 8.75% Senior Secured Notes are secured by a lien on the ultra-
deepwater  floaters  Deepwater  Pontus,  Deepwater  Proteus  and  Deepwater  Thalassa  and  the  harsh  environment  floaters
Transocean Enabler and Transocean Encourage, together with certain related assets.  Additionally, we are required to maintain
certain  balances  in  a  restricted  cash  account  to  satisfy  debt  service  requirements.    We  may  redeem  all  or  a  portion  of  the
8.75% Senior Secured Notes on or prior to February 15, 2026 at a price equal to 100 percent of the aggregate principal amount
plus a make-whole premium, and subsequently, at specified redemption prices.

In  October  2023,  we  issued  $325  million  aggregate  principal  amount  of  8.00%  senior  secured  notes  due
September 2028 (the “8.00% Senior Secured Notes”), and we received $319 million aggregate cash proceeds, net of issue costs.
  The  8.00%  Senior  Secured  Notes  are  secured  by  the  assets  and  certain  earnings  associated  with  the  ultra-deepwater  floater
Deepwater  Aquila  as  well  as  the  equity  of  certain  of  the  wholly  owned  subsidiaries  that  own  or  operate  the  collateral  rig.
 Additionally, we are required to maintain certain balances in a restricted cash account to satisfy debt service requirements.  We
may  redeem  all  or  a  portion  of  the  8.00%  Senior  Secured  Notes  on  or  prior  to  September  30,  2025  at  a  price  equal  to
100 percent of the aggregate principal amount plus a make-whole premium, and subsequently, at specified redemption prices.

Senior guaranteed exchangeable bonds—In September 2022, we issued $300 million aggregate principal amount of
4.625%  Senior  Guaranteed  Exchangeable  Bonds  in  connection  with  exchange  and  purchase  agreements.    Pursuant  to  the
exchange and purchase agreements, we exchanged (the “2022 Private Exchange”) (a) $73 million aggregate principal amount of
the 0.50% exchangeable senior bonds due January 2023 (the “0.50% Exchangeable Senior Bonds”) for (i) $73 million aggregate
principal amount of 4.625% Senior Guaranteed Exchangeable Bonds and (ii) 6.7 million warrants to purchase Transocean Ltd.
shares, and (b) $43 million aggregate principal amount of the 7.25% senior notes due November 2025 for $39 million aggregate

Exchangeable Bonds.  In the year ended December 31, 2022, as a result of the 2022 Private Exchange, we recognized a gain of
$6  million  ($0.01  per  diluted  share),  with  no  tax  effect,  associated  with  the  retirement  of  debt.    Additionally,  we  sold
$188  million  aggregate  principal  amount  of  the  4.625%  Senior  Guaranteed  Exchangeable  Bonds  and  issued  15.5  million
warrants to purchase Transocean Ltd. shares for aggregate net cash proceeds of $188 million.  On or after March 30, 2026, we
may  redeem  for  cash  all  or  a  portion  of  the  4.625%  Senior  Guaranteed  Exchangeable  Bonds  at  a  price  equivalent  to  the
aggregate principal amount to be redeemed if the closing price of our shares has been greater than 115 percent of the exchange
price  for  a  period  of  at  least  20  trading  days.    The  initial  carrying  amount  of  the  4.625%  Senior  Guaranteed  Exchangeable
Bonds,  measured  at  the  estimated  fair  value  on  the  date  of  issuance,  was  $281  million.    We  estimated  the  fair  value  of  the
exchangeable debt instrument, including the exchange feature, by employing a binomial lattice model and by using significant
other observable inputs, representative of Level 2 fair value measurements, including the terms and credit spreads of our debt
and expected volatility of the market price for our shares.  See Note 14—Equity.

In February 2021, we issued $294 million aggregate principal amount of the 4.00% Senior Guaranteed Exchangeable
Bonds  and  made  an  aggregate  cash  payment  of  $11  million  in  private  exchanges  (the  “2021  Private  Exchange”)  for
$323 million aggregate principal amount of the 0.50% Exchangeable Senior Bonds.  In the year ended December 31, 2021, as a
result  of  the  2021  Private  Exchange,  we  recognized  a  gain  of  $51  million  ($0.08  per  diluted  share),  with  no  tax  effect,
associated  with  the  retirement  of  debt.    The  initial  carrying  amount  of  the  4.00%  Senior  Guaranteed  Exchangeable  Bonds,
measured at the estimated fair value on the date of issuance, was $260 million.  We estimated the fair value of the exchangeable
debt  instrument,  including  the  exchange  feature,  by  employing  a  binomial  lattice  model  using  significant  other  observable
inputs,  representative  of  Level  2  fair  value  measurements,  including  the  terms  and  credit  spreads  of  our  debt  and  expected
volatility of the market price for our shares.

Debt repayment, redemption, and retirement

Early  retirement—During  the  three  years  ended  December  31,  2023,  we  retired  certain  notes  as  a  result  of
redemptions  or  private  exchanges.    The  aggregate  principal  amounts,  cash  payments  and  recognized  gain  or  loss  for  such
transactions were as follows (in millions):

holders in October 2023.

Scheduled  maturities  and  installments—On  the  scheduled  maturity  date  of  January  30,  2023,  we  made  a  cash
payment  of  $49  million  to  repay  an  equivalent  aggregate  principal  amount  of  the  outstanding  0.50%  Exchangeable  Senior
Bonds.  On the scheduled maturity date of December 15, 2021, we made a cash payment of $38 million to repay an equivalent
aggregate  principal  amount  of  the  outstanding  6.375%  senior  notes  due  December  2021.    In  the  years  ended  December  31,

repay other indebtedness in scheduled installments.

NOTE 10—POSTEMPLOYMENT BENEFIT PLANS

Defined contribution plans

We sponsor defined contribution plans for our employees in most markets in which we operate worldwide, the most
significant  of  which  were  as  follows:  (1)  a  qualified  savings  plan  covering  certain  eligible  employees  working  in  the  U.S.,
(2)  various  savings  plans  covering  eligible  employees  working  in  Norway,  (3)  a  non-qualified  savings  plan  covering  certain
eligible  employees  working  outside  the  U.S.,  the  United  Kingdom  (“U.K.”)  and  Norway  and  (4)  a  qualified  savings  plan
covering certain eligible employees working in the U.K.  In the years ended December 31, 2023, 2022 and 2021, we recognized
expense of $58 million, $61 million and $52 million, respectively, recorded in the same financial statement line item as cash
compensation paid to the respective employees, related to our defined contribution plans.

Defined benefit pension and other postemployment benefit plans

Overview—As  of  December  31,  2023,  we  had  defined  benefit  plans  in  the  U.S.,  including  three  funded  and
three  unfunded  defined  benefit  plans  (the  “U.S.  Plans”),  and  in  the  U.K.,  we  had  one  funded  defined  benefit  plan  (the
“U.K. Plan”).  During the year ended December 31, 2021, as required by local authorities, we terminated our remaining plans in
Norway (together with the U.K. Plan, the “Non-U.S. Plans”).  We also maintain certain unfunded other postemployment benefit
plans (collectively, the “OPEB Plans”), under which benefits to eligible participants diminish during a phase-out period ending
December 31, 2025.  We maintain the benefit obligations under our defined benefit plans until they are fully satisfied.

We  periodically  review  our  investment  policies,  plan  assets  and  asset  allocation  strategies  to  evaluate  performance
relative  to  specified  objectives.    In  determining  our  asset  allocation  strategies  for  the  U.S.  Plans,  we  review  the  results  of
regression  models  to  assess  the  most  appropriate  target  allocation  for  each  plan,  given  the  plan’s  status,  demographics  and
duration.  For the U.K. Plan, the plan trustees establish the asset allocation strategies consistent with the regulations of the U.K.
pension  regulators  and  in  consultation  with  financial  advisors  and  company  representatives.    Investment  managers  for  the
U.S. Plans and the U.K. Plan are given established ranges within which the investments may deviate from the target allocations.

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

We  estimated  the  fair  values  of  the  plan  assets  by  applying  the  market  approach,  as  categorized  above,  using  either
(i) significant observable inputs, representative of Level 1 fair value measurements, including market prices of actively traded
funds, or (ii) significant other observable inputs, representative of Level 2 fair value measurements, including market prices of
the underlying securities in the trust funds.  The U.S. Plans and the U.K. Plan invest in passively and actively managed funds
that are referenced to or benchmarked against market indices.  The plan investment managers have discretion to select securities
within each asset category.  Given this discretion, the plans may occasionally hold either long or short positions in our debt or
equity securities.  Since plan investment managers are required to maintain well diversified portfolios, the actual investment in
our securities would be immaterial relative to asset categories and the overall plan assets.

Funding contributions and benefit payments—In the years ended December 31, 2023, 2022 and 2021, we made an
aggregate  contribution  of  $8  million,  $3  million  and  $10  million,  respectively,  to  the  defined  benefit  pension  plans  and  the
OPEB Plans using our cash flows from operations.  In the year ending December 31, 2024, we expect to make an aggregate
contribution  of  $4  million,  including  $1  million  and  $3  million  to  the  defined  benefit  pension  plans  and  the  OPEB  Plans,
respectively.

The projected benefits payments were as follows (in millions):

Overview—Transocean  Ltd.,  a  holding  company  and  Swiss  resident,  is  subject  to  Swiss  federal,  cantonal  and
communal income tax.  For Swiss income taxes, however, qualifying net dividend income and net capital gains on the sale of
qualifying investments in subsidiaries are exempt from taxation.  Consequently, there is not a direct relationship between our
Swiss earnings before income taxes and our Swiss income tax expense.

Tax provision and rate—The components of our income tax provision (benefit) were as follows (in millions):

Current tax expense (benefit)
Deferred tax expense

In  the  years  ended  December  31,  2023,  2022  and  2021,  our  effective  tax  rate  was  (1.4)  percent,  (10.4)  percent  and
(25.7) percent, respectively, based on loss before income tax expense.  The relationship between our provision for or benefit
from income taxes and our income or loss before income taxes can vary significantly from period to period considering, among
other  factors,  (a)  the  overall  level  of  income  before  income  taxes,  (b)  changes  in  the  blend  of  income  that  is  taxed  based  on
gross  revenues  rather  than  income  before  taxes,  (c)  rig  movements  between  taxing  jurisdictions  and  (d)  our  rig  operating
structures.

A reconciliation of the income tax benefit computed at the Swiss holding company federal statutory rate of 7.83% and

our reported consolidated income tax expense was as follows (in millions):

Income tax benefit at Swiss federal statutory rate
Earnings subject to rates different than the Swiss federal statutory rate
Deemed profits taxes
Withholding taxes
Changes in valuation allowance
Changes in unrecognized tax benefits, net
Swiss Federal Act on Tax Reform and AHV Financing

In  January  2020,  Switzerland  made  effective  the  Federal  Act  on  Tax  Reform  and  AHV  Financing  (“TRAF”).    In
March 2020, we entered into discussions with the Swiss tax authorities regarding the manner by which the TRAF applies to
certain Swiss subsidiaries, which

allows  us  to  access  historic  depreciation  and  costs  related  to  financing  assets  not  previously  deducted  on  Swiss  tax  returns,
which can be apportioned to offset taxable income based on the remaining useful lives of the rigs and financing assets.  In the
three  months  ended  December  31,  2021,  we  reached  an  agreement  with  the  Swiss  Tax  authorities  regarding  the  TRAF
treatment.  At December 31, 2023 and 2022, we had a deferred tax liability of $264 million and $226 million, respectively, and
a deferred tax asset of $1.21 billion and $1.23 billion, respectively, offset with a valuation allowance of $1.10 billion, associated
with TRAF.

We include taxes related to the earnings of all of our subsidiaries since we do not consider the earnings of any of our

subsidiaries to be indefinitely reinvested.

At  December  31,  2023  and  2022,  our  deferred  tax  assets  included  U.S.  tax  credits  of  $4  million  and  $11  million,
respectively, which will expire between 2024 and 2026.  Deferred tax assets related to our net operating losses were generated
in  various  worldwide  tax  jurisdictions.   At  December  31,  2023,  our  net  deferred  tax  assets  related  to  our  net  operating  loss
carryforwards included $585 million, which do not expire, and $855 million, which will expire between 2024 and 2041.

As  of  December  31,  2023,  our  consolidated  cumulative  loss  incurred  over  the  recent  three-year  period  represented
significant objective negative evidence for the evaluation of the realizability of our deferred tax assets.  Because such evidence
has limited our ability to consider other subjective evidence, we evaluate each jurisdiction separately.  We consider objective
evidence, such as contract backlog activity, in jurisdictions in which we have profitable contracts, and the ability to carryback
losses or utilize losses against potential exposures.  If estimated future taxable income changes during the carryforward periods
or if the cumulative loss is no longer present, we may adjust the amount of deferred tax assets that we expect to realize.  At
December 31, 2023 and 2022, due to uncertainty of realization, we had a valuation allowance of $1.88 billion and $1.91 billion,
respectively, on net operating losses and other deferred tax assets due to the uncertainty of realization.

Unrecognized  tax  benefits—The  changes  to  unrecognized  tax  benefits,  excluding  interest  and  penalties  that  we

In the years ended December 31, 2023, 2022 and 2021, we recognized, as a component of our income tax provision,
benefit of $18 million, expense of $6 million and expense of $8 million, respectively, related to interest and penalties associated
with  our  unrecognized  tax  benefits.    As  of  December  31,  2023,  we  have  unrecognized  benefits  of  $458  million,  including
interest and penalties, against which we have recorded net operating loss deferred tax assets of $411 million, resulting in net
unrecognized  tax  benefits  of  $47  million,  including  interest  and  penalties,  that  upon  reversal  would  favorably  impact  our
effective  tax  rate.    During  the  year  ending  December  31,  2024,  it  is  reasonably  possible  that  our  existing  liabilities  for
unrecognized  tax  benefits  may  increase  or  decrease,  primarily  due  to  the  progression  of  open  audits  and  the  expiration  of
statutes  of  limitation.    However,  we  cannot  reasonably  estimate  a  range  of  potential  changes  in  our  existing  liabilities  for
unrecognized tax benefits due to various uncertainties, such as the unresolved nature of various audits.

Tax  positions  and  returns—We  conduct  operations  through  our  various  subsidiaries  in  countries  throughout  the
world.    Each  country  has  its  own  tax  regimes  with  varying  nominal  rates,  deductions  and  tax  attributes  that  are  subject  to
changes  resulting  from  new  legislation,  interpretation  or  guidance.    From  time  to  time,  as  a  result  of  these  changes,  we  may
revise previously evaluated tax positions, which could cause us to adjust our recorded tax assets and liabilities.  Tax authorities
in certain jurisdictions are examining our tax returns and, in some cases, have issued assessments.  We intend to defend our tax
positions vigorously.  Although we can provide no assurance as to the outcome of the aforementioned changes, examinations or
assessments, we do not expect the ultimate liability to have a material adverse effect on our consolidated statement of financial
position or results of operations; however, it could have a material adverse effect on our consolidated statement of cash flows.

Brazil tax investigations—In December 2005, the Brazilian tax authorities began issuing tax assessments with respect
to  our  tax  returns  for  the  years  2000  through  2004.    In  May  2014,  the  Brazilian  tax  authorities  issued  an  additional  tax
assessment  for  the  years  2009  and  2010.    We  filed  protests  with  the  Brazilian  tax  authorities  for  the  assessments  and  are
engaged in the appeals process, and a portion of two cases were favorably closed.  As of December 31, 2023, the remaining
aggregate  tax  assessment,  including  interest  and  penalties,  was  for  corporate  income  tax  of  BRL  698  million,  equivalent  to
approximately  $144  million,  and  indirect  tax  of  BRL  90  million,  equivalent  to  $19  million.    We  believe  our  returns  are
materially  correct  as  filed,  and  we  are  vigorously  contesting  these  assessments.   An  unfavorable  outcome  on  these  proposed
assessments  could  have  a  material  adverse  effect  on  our  consolidated  statement  of  financial  position,  results  of  operations  or
cash flows.

Letters of credit and surety bonds

At December 31, 2023 and 2022, we had outstanding letters of credit totaling $16 million and $8 million, respectively,
issued  under  various  committed  and  uncommitted  credit  lines  provided  by  banks  to  guarantee  various  contract  bidding,
performance activities and customs obligations.  At December 31, 2023 and 2022, we also had outstanding surety bonds totaling
$198  million  and  $161  million,  respectively,  to  secure  customs  obligations  related  to  the  importation  of  our  rigs  and  certain
performance and other obligations.  At December 31, 2023 and 2022, the aggregate cash collateral held by institutions to secure
our letters of credit and surety bonds was $7 million.

Legal proceedings

Asbestos  litigation—In  2014,  several  of  our  subsidiaries  were  named,  along  with  numerous  other  unaffiliated
defendants, in complaints filed in Louisiana.  The plaintiffs, former employees of some of the defendants, generally allege that
the defendants used or manufactured asbestos-containing drilling mud additives for use in connection with drilling operations,
claiming negligence, products liability, strict liability and claims allowed under the Jones Act and general maritime law.  One of
our  subsidiaries  has  been  named  in  similar  complaints  filed  in  Illinois,  Missouri  and  California.    At  December  31,  2023,
seven  plaintiffs  have  claims  pending  in  Louisiana  and  15  plaintiffs  in  the  aggregate  have  claims  pending  in  either  Illinois,
Missouri, or California, in which we have or may have an interest.  We intend to defend these lawsuits vigorously, although we
can provide no assurance as to the outcome.  We historically have maintained broad liability insurance, although we can provide
no assurance as to whether insurance will cover the liabilities, if any, arising out of these claims.  Based on our evaluation of the
exposure  to  date,  we  do  not  expect  the  liability,  if  any,  resulting  from  these  claims  to  have  a  material  adverse  effect  on  our
consolidated statement of financial position, results of operations or cash flows.

One of our subsidiaries was named as a defendant, along with numerous other companies, in lawsuits arising out of the
subsidiary’s manufacture and sale of heat exchangers, and involvement in the construction and refurbishment of major industrial
complexes  alleging  bodily  injury  or  personal  injury  as  a  result  of  exposure  to  asbestos.    As  of  December  31,  2023,  the
subsidiary  was  a  defendant  in  approximately  257  lawsuits  with  a  corresponding  number  of  plaintiffs.    For  many  of  these
lawsuits, we have not been provided sufficient information from the plaintiffs to determine whether all or some of the plaintiffs
have claims against the subsidiary, the basis of any such claims, or the nature of their alleged injuries.  The operating assets of
the subsidiary were sold in 1989.  In December 2021, the subsidiary and certain insurers agreed to a settlement of outstanding
disputes that provide the subsidiary with cash.  An earlier settlement, achieved in September 2018, provided the subsidiary with
cash and an annuity that begins making payments in 2024.  Together with a coverage-in-place agreement with certain insurers
and  additional  coverage  issued  by  other  insurers,  we  believe  the  subsidiary  has  sufficient  resources  to  respond  to  both  the
current lawsuits as well as future lawsuits of a similar nature.  While we cannot predict or provide assurance as to the outcome
of these matters, we do not expect the ultimate liability, if any, resulting from these claims to have a material adverse effect on
our consolidated statement of financial position, results of operations or cash flows.

Other matters—We  are  involved  in  various  regulatory  matters  and  a  number  of  claims  and  lawsuits,  asserted  and
unasserted, all of which have arisen in the ordinary course of our business.  We do not expect the liability, if any, resulting from
these other matters to have a material adverse effect on our consolidated statement of financial position, results of operations or
cash flows.  We cannot predict with certainty the outcome or effect of any of the litigation matters specifically described above
or  of  any  such  other  pending,  threatened,  or  possible  litigation  or  liability.   We  can  provide  no  assurance  that  our  beliefs  or
expectations  as  to  the  outcome  or  effect  of  any  tax,  regulatory,  lawsuit  or  other  litigation  matter  will  prove  correct  and  the
eventual outcome of these matters could materially differ from management’s current estimates.

Environmental matters

We have certain potential liabilities under the Comprehensive Environmental Response, Compensation, and Liability
Act (“CERCLA”) and similar state acts regulating cleanup of hazardous substances at various waste disposal sites, including
those  described  below.    CERCLA  is  intended  to  expedite  the  remediation  of  hazardous  substances  without  regard  to  fault.
 Potentially responsible parties (“PRPs”) for each site include present and former owners and operators of, transporters to and
generators of the substances at the site.  It is difficult to quantify the potential cost of environmental matters and remediation
obligations.  Liability is strict and can be joint and several.

One of our subsidiaries was named as a PRP in connection with a site located in Santa Fe Springs, California, known
as  the  Waste  Disposal,  Inc.  site.    We  and  other  PRPs  agreed,  under  a  participation  agreement  with  the  U.S.  Environmental
Protection Agency (the “EPA”) and the U.S. Department of Justice, to settle our potential liabilities by remediating the site.  The
remedial  action  for  the  site  was  completed  in  2006.    Our  share  of  the  ongoing  operating  and  maintenance  costs  has  been
insignificant, and we do not expect any additional potential liabilities to be material.  Resolutions of other claims by the EPA,
the  involved  state  agency  or  PRPs  are  at  various  stages  of  investigation.    Nevertheless,  based  on  available  information  with
respect to all environmental matters, including all related pending legal proceedings, asserted legal claims and known potential
legal claims that are likely to be asserted, we do not expect the ultimate liability, if any, resulting from such matters, to have a
material adverse effect on our consolidated statement of financial position, results of operations or cash flows.

NOTE 14—EQUITY

Share  issuance—In  September  2023,  we  issued  11.9  million  Transocean  Ltd.  shares  with  an  aggregate  value  of
$99  million  to  acquire  the  outstanding  ownership  interests  of  Liquila  (see  Note  4—Unconsolidated  Affiliates  and  Note  7—
Long-Lived Assets).    In  the  year  ended  December  31,  2023,  we  issued  65.1  million  shares  to  certain  holders  that  elected  to
exchange exchangeable bonds under terms of the governing indentures (see Note 9—Debt).

We maintain an at-the-market equity offering program (the “ATM Program”).  We intend to use the net proceeds from
our  ongoing  ATM  Program  for  general  corporate  purposes,  which  may  include,  among  other  things,  the  repayment  or
refinancing of indebtedness and the funding of working capital, capital expenditures, investments and additional balance sheet
liquidity.  In June 2021, we entered into an equity distribution agreement with a sales agent for the offer and sale of our shares,
with a maximum aggregate net offering price of up to $400 million, under the ATM Program.  In August 2022, we entered into
an equity distribution agreement with a sales agent for the offer and sale of our shares, with a maximum aggregate net offering
price of up to $435 million, under the ATM Program.  In the year ended December 31, 2023, we did not issue any shares under
the ATM Program.  In the years ended December 31, 2022 and 2021, we received aggregate cash proceeds of $263 million and
$158 million, respectively, net of issue costs, for the aggregate sale of 61.0 million shares and 36.1 million shares, respectively,
under the ATM Program.

Warrants—In September 2022, we issued 22.2 million warrants to purchase Transocean Ltd. shares.  The warrants
may be exercised by holders at any time prior to the close of business on March 13, 2026 at an exercise price equal to $3.71 per
share,  subject  to  certain  anti-dilutive  adjustments,  and  at  our  election,  such  exercise  may  be  settled  by  delivering  cash,
Transocean  Ltd.  shares  or  a  combination  of  cash  and  shares.    If  at  any  time  prior  to  expiration,  the  closing  price  of
Transocean Ltd. shares equals or exceeds $10.00 per share, subject to adjustment upon the occurrence of certain events, for a
period of five consecutive trading days, we will have the right to effect an exercise of all, but not less than all, of the warrants
upon notice to holders.  The initial carrying amount of the warrants, recorded in additional paid-in capital and measured at the
estimated fair value on the date of issuance, was $16 million, net of issue costs.  We estimated the fair value of the warrants by
employing  a  binomial  lattice  model  and  by  using  significant  other  observable  inputs,  representative  of  Level  2  fair  value
measurements, including the expected volatility of the market price for our shares.

Shares held by subsidiaries—One of our subsidiaries holds our shares for future use to deliver shares in connection
with sales under the ATM Program and in connection with awards granted under our incentive plans or other rights to acquire
our shares.  At December 31, 2023 and 2022, our subsidiary held 34.7 million and 75.4 million shares, respectively.

NOTE 15—SHARE-BASED COMPENSATION

Overview

We  have  a  long-term  incentive  plan  (the  “Long-Term  Incentive  Plan”)  for  executives,  key  employees  and  non-
employee  directors  under  which  awards  can  be  granted  in  the  form  of  restricted  share  units,  restricted  shares,  stock  options,
stock appreciation rights and cash performance awards.  Awards may be granted as service awards that are earned over a defined
service  period  or  as  performance  awards  that  are  earned  based  on  the  achievement  of  certain  market  factors  or  performance
targets  or  a  combination  of  market  factors  and  performance  targets.    The  compensation  committee  of  our  board  of  directors
determines the terms and conditions of the awards granted under the Long-Term Incentive Plan.  At December 31, 2023, we had
115.7  million  shares  authorized  and  31.2  million  shares  available  to  be  granted  under  the  Long-Term  Incentive  Plan.    At
December  31,  2023,  the  total  unrecognized  compensation  cost  related  to  our  unvested  share-based  awards  was  $42  million,
which we expect to recognize over a weighted-average period of 1.72 years.

Service awards typically vest either in three  equal  annual  installments  beginning  on  the  first  anniversary  date  of  the
grant or in an aggregate installment at the end of the stated vesting period.  Service-based stock options, once fully vested, are
typically exercisable during

- 67 -

Table of Contents

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

a  seven-year  period.    Performance  awards  are  typically  subject  to  a  three-year  measurement  period  and  typically  vest  in
one aggregate installment following the ultimate determination date.

Service awards

Restricted  share  units—A  restricted  share  unit  subject  to  service  requirements  is  a  notional  unit  that  is  equal  to
one share but has no voting rights until the underlying share is issued.  The following table summarizes unvested activity during
the year ended December 31, 2023 for service-based units granted under our incentive plan:

Performance awards

Restricted share units—A restricted share unit subject to performance requirements is a notional unit for which the
awarded  number  of  shares  to  be  issued  per  unit  remains  uncertain  until  quantified  as  of  the  ultimate  determination  date
following  completion  of  the  performance  period.  The  following  table  summarizes  unvested  activity  during  the  year  ended

In the year ended December 31, 2022, we borrowed an aggregate principal amount of $439 million under the
Shipyard Loans to satisfy a portion of the final milestone payments due upon delivery of Deepwater Atlas and
Deepwater Titan and recorded the initial carrying amount, net of imputed interest, with a corresponding entry to
construction in progress, recorded in property and equipment.  See Note 7—Long-Lived Assets and Note 9—

In September 2023, we issued 11.9 million Transocean Ltd. shares to acquire the outstanding ownership interests
in Liquila.  See Note 4—Unconsolidated Affiliates, Note 7—Long-Lived Assets and Note 14—Equity.
In September 2023, we agreed to exchange borrowings due to us under a financing arrangement with Orion for

Cash  and  cash  equivalents—Our  cash  and  cash  equivalents  are  primarily  invested  in  demand  deposits,  short-term
time deposits and money market funds.  The carrying amount of our cash and cash equivalents represents the historical cost,
plus accrued interest, which approximates fair value because of the short maturities of the instruments.

Restricted cash and cash equivalents—Our restricted cash and cash equivalents, which are subject to restrictions due
to collateral requirements, legislation, regulation or court order, are primarily invested in demand deposits and money market
funds.    The  carrying  amount  of  our  restricted  cash  and  cash  equivalents  represents  the  historical  cost,  plus  accrued  interest,
which approximates fair value because of the short maturities of the instruments.

Long-term loans receivable from unconsolidated affiliates—The carrying amount of our long-term loans receivable
from unconsolidated affiliates, recorded in other assets, represents the principal amount of the cash investment.  We estimated
the  fair  value  of  our  long-term  loans  receivable  from  unconsolidated  affiliates  using  significant  unobservable  inputs,
representative of Level 3 fair value measurements, including the terms and credit spreads for the instruments.

TRANSOCEAN LTD. AND SUBSIDIARIES
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS—continued

Total debt—The carrying amount of our total debt represents the principal amount, contractual interest payments of
previously restructured debt and unamortized discounts, premiums and issue costs.  The carrying amount and fair value of our
total debt includes amounts related to certain exchangeable debt instruments (see Note 9—Debt).  We estimated the fair value of
our total debt using significant other observable inputs, representative of Level 2 fair value measurements, including the terms
and  credit  spreads  for  the  instruments  and,  with  respect  to  the  exchangeable  debt  instruments,  the  expected  volatility  of  the
market price for our shares.

NOTE 19—RISK CONCENTRATION

Interest rate risk—We are exposed to the interest rate risk related to our fixed-rate debt when we refinance maturing
debt with new debt or when we early retire debt in open market repurchases, exchanges or other market transactions.  We are
also  exposed  to  interest  rate  risk  related  to  our  restricted  and  unrestricted  cash  equivalents,  as  the  interest  income  earned  on
these investments is based on variable or short-term interest rates, which change with market interest rates.

Equity price risk—We are exposed to equity price risk primarily related to the bifurcated compound exchange feature
contained within the 4.625% Senior Guaranteed Exchangeable Bonds.  The market price of our shares is the primary driver of
the fair value of the exchange feature.  An increase to the market price of our shares yields an increase to the carrying amount of
the exchange feature, recorded as a component of our debt, and a corresponding increase to interest expense.

Currency exchange rate risk—We are exposed to currency exchange rate risk primarily related to contract drilling
revenues,  employee  compensation  costs  and  purchasing  costs  that  are  denominated  in  currencies  other  than  our  functional
currency, the U.S. dollar.  We use a variety of techniques to minimize the exposure to currency exchange rate risk, including the
structuring of customer contract payment terms and occasional use of forward exchange contracts.  Our primary tool to manage
currency  exchange  rate  risk  involves  structuring  customer  contracts  to  provide  for  payment  in  both  U.S.  dollars  and  local
currency.    The  payment  portion  denominated  in  local  currency  is  based  on  anticipated  local  currency  requirements  over  the
contract term.  Due to various factors, including customer acceptance, local banking laws, national content requirements, other
statutory  requirements,  local  currency  convertibility,  local  inflation  and  revenue  efficiency,  actual  local  currency  needs  may
vary from those realized in the customer contracts, resulting in partial exposure to currency exchange rate risk.  The currency
exchange effect resulting from our international operations generally has not had a material impact on our operating results.

Credit risk—We are exposed to concentrations of credit risk primarily related to our restricted and unrestricted cash
and  cash  equivalents  and  customer  receivables,  both  current  and  long-term.    We  generally  maintain  our  restricted  and
unrestricted  cash  and  cash  equivalents  in  time  deposits  at  commercial  banks  with  high  credit  ratings  or  mutual  funds,  which
invest  exclusively  in  high-quality  money  market  instruments,  and  because  we  limit  the  amount  of  exposure  to  any
one institution, we do not believe we are exposed to any significant credit risk.  Our customer receivables, which are dispersed
in  various  countries,  are  due  from  integrated  energy  companies,  government-owned  or  government-controlled  energy
companies  and  other  independent  energy  companies.    For  such  receivables,  we  establish  an  allowance  for  credit  losses  by
applying an expected loss rate based on current and forecasted future and historical experience.  Although we have encountered
only isolated credit concerns related to independent energy companies, we occasionally require collateral or other security to
support customer receivables.  In certain infrequent instances, when we determine that collection is not reasonably assured, we
may offer extended payment terms and recognize revenues associated with the contract on a cash basis.

Labor agreements—At December 31, 2023, we had a global workforce of approximately 5,800 individuals, including
approximately 370 contractors.  Approximately 42 percent of our total workforce, working primarily in Norway and Brazil, are
represented by, and some of our contracted labor work is subject to, collective bargaining agreements, substantially all of which
are subject to annual salary negotiation.  Negotiations over annual salary or other labor matters could result in higher personnel
or other costs or increased operational restrictions or disruptions.  The outcome of any such negotiation generally affects the
market for all offshore employees, not only union members.  A failure to reach an agreement on certain key issues could result
in strikes, lockouts or other work stoppages.

ITEM 9. CHANGES  IN  AND  DISAGREEMENTS  WITH  ACCOUNTANTS  ON  ACCOUNTING  AND

FINANCIAL DISCLOSURE

We  have  not  had  a  change  in  or  disagreement  with  our  accountants  within  24  months  prior  to  the  date  of  our  most

recent financial statements or in any period subsequent to such date.

ITEM 9A.CONTROLS AND PROCEDURES

Disclosure  controls  and  procedures—Our  disclosure  controls  and  procedures  are  designed  to  provide  reasonable
assurance that information required to be disclosed in our reports filed or submitted under the Exchange Act is (1) accumulated
and communicated to our management, including our Chief Executive Officer, who is our principal executive officer, and our
Chief  Financial  Officer,  who  is  our  principal  financial  officer,  to  allow  timely  decisions  regarding  required  disclosure  and
(2)  recorded,  processed,  summarized  and  reported  within  the  time  periods  specified  in  the  U.S.  Securities  and  Exchange
Commission’s rules and forms.  Under the supervision and with the participation of management, including our Chief Executive
Officer and Chief Financial Officer, we performed an evaluation of the effectiveness of our disclosure controls and procedures
as of the end of the period covered by this report.  Based on that evaluation, our Chief Executive Officer and Chief Financial
Officer concluded that our disclosure controls and procedures were effective as of December 31, 2023.

Internal  control  over  financial  reporting—There  were  no  changes  to  our  internal  control  over  financial  reporting
during  the  quarter  ended  December  31,  2023  that  have  materially  affected  or  are  reasonably  likely  to  materially  affect  our
internal  control  over  financial  reporting.    See  “Management’s  Report  on  Internal  Control  Over  Financial  Reporting”  and
“Report of Independent Registered Public Accounting Firm,” included in Item 8 of this annual report.

ITEM 9B.OTHER INFORMATION

On  December  19,  2023,  Keelan  Adamson,  President  and  Chief  Operating  Officer  of  the  Company,  adopted  a
Rule 10b5-1 trading arrangement (as such term is defined under Item 408(a) of Regulation S-K) that is intended to satisfy the
affirmative  defense  of  Rule  10b5-1(c)  for  the  sale  of  up  to  211,308  shares  of  Transocean  Ltd.  (the  “Plan”).    Sales  may  not
commence under the Plan until March 26, 2024 at the earliest and, for certain of the shares, only at specified market prices.
 Unless earlier terminated in accordance with the terms and conditions of the Plan, the Plan expires on December 19, 2024.

As  part  of  Transocean’s  continued  focus  on  a  succession  planning  strategy  to  support  the  Company’s  long-term
growth, on February 20, 2024, Transocean announced a transition of the role of Chief Financial Officer from Mr. Mark Mey to

DESCRIPTION OF TRANSOCEAN LTD.’S SECURITIES
REGISTERED PURSUANT TO SECTION 12 OF THE
SECURITIES EXCHANGE ACT OF 1934

Exhibit 4.1

As  of  December  31,  2023,  Transocean  Ltd.  had  one  class  of  securities  registered  under  Section  12  of  the

Securities Exchange Act of 1934, as amended: registered shares, par value CHF 0.10 per share (“shares”).

Description of the Shares

The following description of the share capital of Transocean Ltd. is a summary and is subject to the complete
text of our Articles of Association, filed as Exhibit 3.1 to our Current Report on Form 8-K (Commission File No. 001-
38373)  filed  on  September  14,  2023  (the  “Articles  of  Association”).  We  encourage  you  to  read  the  Articles  of
Association carefully. In this description, references to “Transocean,” “we,” “our” and “us” mean Transocean Ltd.
Unless otherwise provided herein, the following description of shares is as of February 14, 2024.

General

Issued  Share  Capital.  As  of  February  14,  2024,  the  share  capital  of  Transocean  registered  shares  in  the
Commercial Register of the Canton of Zug (the “commercial register”), which reflects our total issued share capital,
excluding  shares  issued  out  of  our  conditional  share  capital  not  yet  registered  with  the  commercial  register,  was
84,371,527.60  Swiss  francs,  divided  into  843,715,276  registered  shares,  par  value  0.10  Swiss  francs  per  share.  The
total issued share capital of Transocean, including shares issued out of our conditional share capital not yet registered
with the commercial register, was 84,371,585.80 Swiss francs, divided into 843,715, 858 registered shares, par value
0.10 Swiss francs per share. The issued shares are fully paid, non-assessable, and rank pari passu with each other.

Capital  Authorization  (Capital  Band).  Article  5  of  our  Articles  of  Association  provides  for  a  share
authorization within a capital band, ranging from 83,184,490.00 Swiss francs (lower limit) to 102,129,396.70 Swiss
francs  (upper  limit),  which  allows  our  board  of  directors  to  issue  new  shares  for  general  purposes  and  pursuant  to
benefit and incentive plans.

General  Authorization.  Within  the  capital  authorization  described  above,  Article  5  of  our  Articles  of
Association authorizes our board of directors to issue up to 159,449,067 new fully paid-in shares for general corporate
purposes  at  any  time  until  May  11,  2024,  and  thereby  increase  the  stated  share  capital  from  time  to  time.  A  capital
increase  may  further  be  affected  within  the  range  of  the  capital  band  by  way  of  an  increase  of  the  par  value  of  the
shares (but in any event at a maximum of 15,944,906.70 Swiss francs). Article 5 of our Articles of Association does
not  currently  reflect  the  previous  issuance  of  11,870,376  shares  from  our  general  share  authorization  to  one  of  our
wholly  owned  subsidiaries,  which  shares  were  delivered  as  consideration  for  the  purchase  of  the  outstanding  equity
interests of Liquila Ventures Ltd. Accordingly, the remaining authority to issue shares from our general capital band is
limited to a maximum of 147,578,691 shares.

Our  board  of  directors  determines  the  time  of  the  issuance,  the  issue  price,  the  manner  in  which  the  new
shares have to be paid in, the date from which the new shares carry the right to dividends and, subject to the provisions
of our Articles of Association, the conditions for the exercise of the preemptive rights with respect to the issuance and
the allotment of preemptive rights that are not exercised. The board of directors may allow preemptive rights that are
not exercised to expire, or it may place such rights or shares, the preemptive rights in respect of which have not been
exercised, at market conditions or use them otherwise in our interest. For further information on preemptive rights with
respect to our capital authorization for general purposes, see “—Preemptive Rights and Advance Subscription Rights”
below.

An increase of the share capital by means of an offering underwritten by a financial institution, a syndicate of
financial institutions or another third party or third parties, followed by an offer to the then-existing shareholders of
Transocean is permissible.

The shares will be subject to the limitations for registration in the share register pursuant to Articles 7 and 9

of our Articles of Association.

Specific  Authorization.  Within  the  capital  authorization  described  above,  Article  5  of  our  Articles  of
Association authorizes our board of directors to issue, directly or indirectly, up to 30,000,000 new fully paid-in shares
under  our  benefit  or  incentive  plans  to  members  of  our  board  of  directors,  members  of  our  executive  management
team, officers, employees, contractors, consultants or other persons providing services to us or our subsidiaries at any
time  until  May  11,  2028,  and  thereby  increase  the  stated  share  capital  from  time  to  time.  For  such  purposes,  the
preemptive rights of existing shareholders are excluded. Our board of directors determines the time of the issuance, the
issue price (which may be lower than the current market price), the manner in which the new shares have to be paid
and the date from which the new shares carry the right to dividends.

Conditional Share Capital. Article 6 of our Articles of Association provides for a conditional share capital that
allows Transocean to issue up to 142,362,675 shares and thus an increase of the stated share capital by a maximum
amount of 14,236,267.50 Swiss francs. Consistent with applicable Swiss law, Article 6 of our Articles of Association
does  not  currently  reflect  the  previous  issuance  of  582  shares  out  of  conditional  share  capital  following  and  in
connection  with  the  exchange  of  certain  of  our  exchangeable  bonds.  Accordingly,  the  remaining  authority  to  issue
shares  out  of  conditional  share  capital  is  limited  to  a  maximum  of  142,362,093  shares.  These  shares  may  be  issued
through:

● the exercise of conversion, exchange, option, warrant or similar rights for the subscription of shares granted
to  third  parties  or  shareholders  in  connection  with  bonds,  options,  warrants  or  other  securities  newly  or
already issued in national or international capital markets or new or already existing contractual obligations
by or of us or any of our group companies or any of our respective predecessors; or

● in  connection  with  the  issuance  of  shares,  options  or  other  share-based  awards  to  members  of  the  board  of
directors, members of our executive management team, officers, employees, contractors, consultants or other
persons providing services to us or our subsidiaries.

For information on preemptive rights with respect to our conditional share capital, see “—Preemptive Rights

and Advance Subscription Rights” below.

Other  Classes  or  Series  of  Shares  /  Non-Voting  Stock.  The  board  of  directors  may  not  create  shares  with
increased voting powers (Stimmrechtsaktien) without the affirmative vote of shareholders holding at least two-thirds of
the voting rights and an absolute majority of the par value of the shares, each as represented (in person or by proxy) at
a general meeting of the shareholders. The board of directors may create preferred stock (Vorzugsaktien) with the vote
of  a  relative  majority  of  the  votes  cast  at  a  general  meeting  of  our  shareholders  (not  counting  broker  non-votes,
abstentions  and  blank  or  invalid  ballots).  We  have  not  issued  any  non-voting  stock  to  date  (Partizipationsscheine,
Genussscheine).

Preemptive Rights and Advance Subscription Rights

Under  the  Swiss  Code  of  Obligations  (the  “Swiss  Code”),  the  prior  approval  of  a  general  meeting  of
shareholders is generally required to authorize, for later issuance, the issuance of shares, or rights to subscribe for, or
convert into, shares (which rights may be connected to debt instruments or other obligations). In addition, the existing
shareholders will have preemptive rights in relation to such shares or rights in proportion to the respective par values
of their holdings (Bezugsrechte). The shareholders may, with the affirmative vote of shareholders holding two-thirds of
the votes and the absolute majority of the par value of the shares represented at the general meeting, withdraw or limit
the preemptive rights for valid reasons (such as a merger, an acquisition or any of the reasons authorizing the board of
directors to withdraw or limit the preemptive rights of shareholders in the context of an authorized capital increase as
described below).

If  the  general  meeting  of  shareholders  has  approved  the  creation  of  a  capital  band  or  conditional  capital,  it
may withdraw or restrict preemptive and advance subscription rights for valid reasons or delegate such decision to the
board of directors. If delegated, the valid reasons justifying the exclusion of the preemptive right must be stated in the
articles of association. Our Articles of Association provide for this delegation and state the valid reasons with respect
to our capital band and conditional share capital in the circumstances described below under “—Capital Band (Capital
Authorization)” and “—Conditional Share Capital.”

2

Capital  Authorization  (Capital  Band).  At  any  time  until  May  11,  2024,  and  pursuant  to  Article  5  of  our
Articles  of  Association,  our  board  of  directors  is  authorized  to  withdraw  or  restrict  the  preemptive  rights  of  the
shareholders  with  respect  to  a  maximum  of  159,449,067  shares  issued  for  general  purposes  and  to  allot  them  to
individual shareholders, third parties, Transocean or any of its group companies with respect to the issuance of shares
within the capital band if:

● the issue price of the new shares is determined by reference to the market price;

● the shares are issued for raising equity capital in a fast and flexible manner, which would not be possible, or
would  only  be  possible  with  great  difficulty  or  at  significantly  less  favorable  conditions,  without  the
withdrawal of the preemptive rights of existing shareholders;

● the shares are issued in connection with the acquisition of companies, part(s) of companies or participations,
for  the  acquisition  of  products,  intellectual  property  or  licenses  by  or  for  investment  projects  of  the
Transocean or any of its group companies, or the financing or refinancing of any such transactions through a
placement of shares;

● the  shares  are  issued  in  connection  with  the  intended  broadening  of  the  shareholder  constituency  of
Transocean in certain financial or investor markets, for the purposes of the participation of strategic partners,
including  financial  investors,  or  in  connection  with  the  listing  of  the  shares  on  domestic  or  foreign  stock
exchanges; or

● in connection with a placement or sale of shares, the grant of an over-allotment option of up to 20% of the

total number of shares to the initial purchaser(s) or underwriter(s) thereof.

Pursuant  to  Article  5  of  our  Articles  of  Association,  the  preemptive  rights  of  existing  shareholders  are
excluded  with  respect  to  up  to  30,000,000  shares  that  our  board  of  directors  is  authorized  to  issue,  directly  or
indirectly,  within  the  capital  band  under  our  benefit  or  incentive  compensation  plans  to  members  of  our  board  of
directors,  members  of  our  executive  management  team,  employees,  contractors,  consultants  and  other  persons
performing services to us or of any of our subsidiaries.

Conditional  Share  Capital.  In  connection  with  the  issuance  of  bonds,  notes,  options,  warrants  or  other
securities  or  contractual  obligations  convertible  into  or  exercisable  or  exchangeable  for  our  shares,  the  preemptive
rights  of  shareholders  are  excluded  and  the  board  of  directors  is  authorized  to  withdraw  or  limit  the  advance
subscription rights (Vorwegzeichnungsrecht) of shareholders in connection with the issuance of bonds, notes, options,
warrants or other securities or contractual obligations convertible into or exercisable or exchangeable for our shares if
the  issuance  is  for  purposes  of  financing  or  refinancing  the  acquisition  of  an  enterprise  or  business,  parts  of  an
enterprise,  participations  or  investments,  or  if  the  issuance  occurs  in  national  or  international  capital  markets  or
through a private placement.

If the advance subscription rights are withdrawn or limited:

● such securities or contractual obligations will be issued or entered into at market conditions;

● the  conversion,  exchange  or  exercise  price,  if  any,  for  such  securities  or  contractual  obligations  will  be  set
with  reference  to  the  market  conditions  prevailing  at  the  date  on  which  such  securities  or  obligations  are
issued or entered into; and

● such  securities  or  contractual  obligations  may  be  converted,  exercised  or  exchanged  during  a  maximum

period of 30 years.

The preemptive rights and the advance subscription rights of shareholders are excluded with respect to shares,
bonds, notes, options, warrants or other securities or contractual obligations issued from our conditional share capital
under our incentive compensation plans to members of our board of directors, members of our executive management
team, employees, contractors, consultants or other persons providing services to us or any of our subsidiaries.

Dividends and Other Distributions

Under  the  Swiss  Code,  dividends  (including  interim  dividends)  may  be  paid  out  only  if  we  have  sufficient
distributable profits from the previous fiscal year or the current fiscal year, or if we have freely distributable reserves
(including statutory capital contribution reserves, which are also referred to as additional paid-in capital), each as will
be  presented  on  our  audited  annual  stand-alone  statutory  balance  sheet  and  an  audited  interim  stand-alone  statutory
balance  sheet,  respectively.  The  affirmative  vote  of  shareholders  holding  a  relative  majority  of  the  votes  cast  at  a
general meeting of shareholders (not counting broker non-votes, abstentions and blank or invalid ballots) must approve
the distribution of dividends. The board of directors may propose to shareholders that a dividend or other distribution
be paid but cannot itself authorize the distribution.

Payments out of our share capital (in other words, the aggregate par value of our registered share capital) in
the form of dividends are not allowed; however, payments out of registered share capital may be made by way of a par
value  reduction.  Such  a  par  value  reduction  requires  the  approval  of  shareholders  holding  a  relative  majority  of  the
votes  cast  at  the  general  meeting  of  shareholders  (not  counting  broker  non-votes,  abstentions  and  blank  or  invalid
ballots). A special audit report must confirm that claims of our creditors remain fully covered despite the reduction in
the  share  capital  recorded  in  the  commercial  register.  A  licensed  audit  expert  must  prepare  the  audit  report  and  be
present  at  the  general  meeting  of  shareholders  that  adopts  the  resolution.  The  board  of  directors  must  further  give
public notice of the par value reduction resolution in the Swiss Official Gazette of Commerce and notify creditors that
they may request, within one month of the public notice, satisfaction of or security for their claims. The notification
may be given before or after the general meeting of shareholders at which resolutions regarding the par value reduction
were passed.

Under the Swiss Code, if our statutory profit reserves (gesetzliche Gewinnreserve) together with our statutory
capital reserves (gesetzliche Kapitalreserve) amount to less than 20% of our share capital recorded in the commercial
register (i.e., 20% of the aggregate par value of our registered capital), then at least 5% of our annual profit must be
allocated to the statutory profit reserves. The Swiss Code and our Articles of Association permit us to accrue additional
general reserves. In addition, if we acquire our own shares, we are required to account for these shares, if acquired by
our parent company Transocean Ltd., as a negative item in our shareholders’ equity or, if these shares are acquired by
one of our subsidiaries, to create a special reserve, in each case on our audited annual or interim stand-alone statutory
balance  sheet  in  the  amount  of  the  purchase  price  of  the  shares  repurchased  by  our  parent  or  our  subsidiary.  The
negative  item  in  our  shareholders’  equity  or  the  reserve  amount  would  effectively  reduce  our  capacity  to  declare
dividends or effect subsequent repurchases of our shares.

Swiss companies generally must maintain a separate company, stand-alone “statutory” balance sheet for the
purpose of, among other things, determining the amounts available for the return of capital to shareholders, including
by  way  of  a  distribution  of  dividends.  Our  auditor  must  confirm  that  a  proposal  made  by  our  board  of  directors  to
shareholders  regarding  the  appropriation  of  our  available  earnings  or  the  distribution  of  freely  distributable  reserves
conforms  to  the  requirements  of  the  Swiss  Code  and  our  Articles  of  Association.  Dividends  are  usually  due  and
payable  shortly  after  the  shareholders  have  passed  a  resolution  approving  the  payment,  but  shareholders  may  also
resolve  at  the  annual  or  extraordinary  general  meeting  of  shareholders  to  pay  dividends  in  quarterly  or  other
installments. Our Articles of Association provide that dividends that have not been claimed within five years after the
payment  date  become  our  property  and  are  allocated  to  the  general  statutory  reserves.  Dividends  paid  out  of
distributable  profits  or  distributable  general  reserves  are  subject  to  Swiss  withholding  tax,  all  or  part  of  which  can
potentially  be  reclaimed  under  the  relevant  tax  rules  in  Switzerland  or  double  taxation  treaties  concluded  between
Switzerland and foreign countries. Distributions to shareholders in the form of a par value reduction and distributions
out of statutory capital contribution reserves are not subject to the Swiss federal withholding tax.

Dividends, if declared by us, are expected to be declared, subject to applicable limitations under Swiss law, in
U.S. dollars, or in Swiss francs, and shareholders may be given the right to elect to be paid any such dividends in U.S.
dollars  or  Swiss  francs.  Distribution  through  a  reduction  in  the  par  value  of  the  shares  must  be  declared  in  Swiss
francs; however, shareholders may be provided with the option to elect to be paid in U.S. dollars or Swiss francs.

Repurchases of Shares

The Swiss Code limits our ability to hold or repurchase our own shares. We and our subsidiaries may only

repurchase shares if and to the extent that sufficient freely distributable equity capital is available, as described above

4

under  “—Dividends  and  Other  Distributions.”  The  aggregate  par  value  of  all  of  our  shares  held  by  us  and  our
subsidiaries may not exceed 10% of the registered share capital. However, we may repurchase our own shares beyond
the  statutory  limit  of  10%  if  the  shareholders  have  authorized  our  board  of  directors  at  a  general  meeting  of
shareholders  to  repurchase  shares  in  an  amount  in  excess  of  10%  and  the  repurchased  shares  are  dedicated  for
cancellation. Any shares repurchased pursuant to such an authorization will then be cancelled based on a resolution of
shareholders adopted at a general meeting of shareholders subject to the approval of shareholders holding a relative
majority of the votes cast or, if shareholders have adopted a capital band authorizing our board of directors to reduce
the share capital by way of a cancellation of shares, based on a resolution of the board of directors. Repurchased shares
held  by  us  or  our  subsidiaries  do  not  carry  any  rights  to  vote  at  a  general  meeting  of  shareholders  but  are,  unless
otherwise  resolved  by  our  shareholders  at  a  general  meeting,  entitled  to  the  economic  benefits  generally  associated
with the shares.

General Meetings of Shareholders

The  general  meeting  of  shareholders  is  our  supreme  corporate  body.  Ordinary  and  extraordinary  general
meetings  of  shareholders  may  be  held.  Among  other  things,  the  following  powers  will  be  vested  exclusively  in  the
general meeting of shareholders:

● adoption and amendment of our Articles of Association;

● the  annual  election  of  the  chairman  of  the  board  of  directors,  the  members  of  the  board  of  directors,  the
members of the compensation committee of the board of directors, the auditor and the independent proxy;

● approval of the annual management report, the stand-alone statutory financial statements and the consolidated

financial statements;

● appropriation of the annual profit shown on our annual stand-alone statutory balance sheet, in particular the

distribution of any dividends;

● the determination of interim dividends and the approval of interim stand-alone statutory financial statements

required for such purposes;

● the resolution regarding the repayment of the statutory capital reserves;

● the combination of shares (“reverse stock split”);

● discharge  of  the  members  of  the  board  of  directors  and  the  executive  management  team  from  liability  for
business conduct during the previous fiscal year(s) to the extent such conduct is known to the shareholders;

● ratification of the maximum aggregate amounts of compensation of the board of directors and the executive

management team;

● subject to certain exceptions, the approval of a business combination with an interested shareholder (as such

terms are defined in our Articles of Association);

● the delisting of our shares from a stock exchange;

● the approval of the report on non-financial matters pursuant to article 964c of the Swiss Code; and

● any other resolutions that are submitted to a general meeting of shareholders pursuant to law, our Articles of
Association  or  by  voluntary  submission  by  the  board  of  directors  (unless  a  matter  is  within  the  exclusive
competence of the board of directors pursuant to the Swiss Code).

Notice and Proxy Statements

Under the Swiss Code and our Articles of Association, we must hold an annual, ordinary general meeting of

shareholders within six months after the end of our fiscal year for the purpose, among other things, of approving the

5

annual financial statements and the annual management report, the annual election of the chairperson of our board of
directors,  the  members  of  our  board  of  directors,  the  members  of  the  compensation  committee  of  our  board  of
directors,  our  auditor  and  our  independent  proxy,  and  the  ratification  of  the  maximum  aggregate  amounts  of
compensation of the board of directors and the executive management team. The invitation to general meetings must
be  published  in  the  Swiss  Official  Gazette  of  Commerce  at  least  20  calendar  days  prior  to  the  date  of  the  relevant
general meeting of shareholders. The notice of a meeting must state the items on the agenda and the proposals of the
board  of  directors  and  of  the  shareholders  who  requested  that  a  shareholders  meeting  be  held  or  that  an  item  be
included on the agenda and, in case of elections, the names of the nominated candidates. The notice must also include
a short explanation of the items and proposals on the agenda of the general meeting. No resolutions may be passed at a
general meeting of shareholders concerning agenda items for which proper notice was not given. This does not apply,
however, to proposals made during a general meeting of shareholders to convene an extraordinary general meeting of
shareholders,  to  initiate  a  special  investigation  or  to  elect  the  statutory  auditor.  No  previous  notification  will  be
required for proposals concerning items included on the agenda or for debates as to which no vote is taken.

Annual  general  meetings  of  shareholders  are  convened  by  the  board  of  directors  or,  under  certain
circumstances required by law, by the auditor. A general meeting of shareholders can be held anywhere in Switzerland.
A  special  authorizing  provision  in  the  articles  of  association  is  required  to  hold  a  general  meeting  outside  of
Switzerland. Our current articles of association do not include such an authorization. General meetings that are held
only virtually require a special authorization in the articles of association. Our current Articles of Association do not
include such an authorization.

We expect to set the record date for each general meeting of shareholders on a date not more than 20 calendar
days prior to the date of each general meeting and announce the date of the general meeting of shareholders prior to the
record date.

Extraordinary General Meetings of Shareholders

An extraordinary general meeting may be called upon the resolution of the board of directors or, under certain
circumstances  required  by  law,  by  the  auditor.  In  addition,  the  board  of  directors  is  required  to  convene  an
extraordinary general meeting of shareholders if so resolved by the general meeting of shareholders, or if so requested
by shareholders who, in the aggregate, represent at least 5% of the share capital or votes recorded in the commercial
register, specifying the items to be included on the agenda and their proposals. Upon such a shareholder request, the
board of directors must publish the necessary notice to convene a general meeting within 60 calendar days.

If it appears from the annual stand-alone statutory balance sheet that half of the sum of our share capital, the
non-distributable  statutory  capital  reserves  and  the  statutory  profit  reserves  are  not  covered  by  our  assets
(Kapitalverlust), the board of directors is required to take measures to remedy the capital loss situation of the company,
where necessary take further measures to effect a financial restructuring of the company or request the general meeting
of shareholders to approve such measures as are within its authority.

Agenda Requests

Under  our  Articles  of  Association,  any  shareholder  may  request  that  an  item  or  a  proposal  relating  to  an
agenda item be included on the agenda of a general meeting of shareholders. Such shareholder may also nominate one
or more directors for election. A request for inclusion of an item on the agenda or a proposal relating to an agenda item
must be made in writing at least 30 calendar days prior to the anniversary date of the proxy statement in connection
with  our  last  annual  general  meeting  of  shareholders;  provided,  however,  that  if  the  date  of  the  general  meeting  of
shareholders is more than 30 calendar days before or after the anniversary date of the last annual general meeting of
shareholders, such request must instead be made by the tenth calendar day following the date on which we have made
public disclosure of the date of the general meeting of shareholders. The request must specify in writing the relevant
agenda items and proposals, together with evidence of the required shares recorded in the share register, as well as any
other information as would be required to be included in a proxy statement pursuant to the rules of the U.S. Securities
and Exchange Commission.

Under  the  Swiss  Code,  a  general  meeting  of  shareholders  for  which  a  notice  of  meeting  has  been  duly

published may not be adjourned without publishing a new notice of meeting.

6

Our  annual  report,  our  stand-alone  and  consolidated  financial  statements,  the  auditors’  reports  thereon,  our
compensation report pursuant to Swiss law and the auditor’s reports thereon, and our report on non-financial matters
pursuant to article 964c of the Swiss Code (to the extent required by applicable law) must be made available to our
shareholders no later than 20 calendar days prior to the annual general meeting of shareholders. If these documents are
not accessible electronically, each shareholder may request that these documents be promptly sent to it in due course,
free of charge.

Voting

Each of our shares carries one vote at a general meeting of shareholders. Voting rights may be exercised by
shareholders  registered  in  our  share  register  or  by  a  duly  appointed  proxy  of  a  registered  shareholder  (including  the
independent proxy), which proxy need not be a shareholder. Our Articles of Association do not limit the number of
shares that may be voted by a single shareholder. Shareholders wishing to exercise their voting rights who hold their
shares through a bank, broker or other nominee should follow the instructions provided by such bank, broker or other
nominee  or,  absent  instructions,  contact  such  bank,  broker  or  other  nominee  for  instructions.  Shareholders  holding
their shares through a bank, broker or other nominee will not automatically be registered in our share register. If any
such  shareholder  wishes  to  be  registered  in  our  share  register,  such  shareholder  should  contact  the  bank,  broker  or
other nominee through which it holds our shares.

Treasury shares, whether owned by us or one of our majority-owned subsidiaries, will not be entitled to vote

at general meetings of shareholders.

Our Articles of Association do not provide for cumulative voting for the election of directors.

Pursuant to our Articles of Association, the shareholders generally pass resolutions by the affirmative vote of
a relative majority of the votes cast at the general meeting of shareholders (broker non-votes, abstentions and blank
and invalid ballots will be disregarded), unless otherwise provided by law or our Articles of Association. However, our
Articles of Association provide that directors may be elected at a general meeting of shareholders by a plurality of the
votes  cast  by  the  shareholders  present  in  person  or  by  proxy  at  the  meeting.  Our  Corporate  Governance  Guidelines
have  a  majority  vote  policy  that  provides  that  the  board  may  nominate  only  those  candidates  for  director  who  have
submitted  an  irrevocable  letter  of  resignation  which  would  be  effective  upon  and  only  in  the  event  that  (1)  such
nominee fails to receive a sufficient number of votes from shareholders in an uncontested election and (2) the board
accepts the resignation following such failure. If a nominee who has submitted such a letter of resignation does not
receive  more  votes  cast  “for”  than  “against”  the  nominee’s  election,  the  corporate  governance  committee  must
promptly  review  the  letter  of  resignation  and  recommend  to  the  board  of  directors  whether  to  accept  the  tendered
resignation or reject it. The board of directors must then act on the corporate governance committee’s recommendation
within 90 days following the shareholder vote. The board of directors must promptly disclose its decision regarding
whether or not to accept the nominee’s resignation letter.

The  acting  chair  may  direct  that  resolutions  and  elections  be  held  by  use  of  an  electronic  voting  system.

Electronic resolutions and elections are considered equal to resolutions and elections taken by way of a written ballot.

The Swiss Code and/or our Articles of Association require the affirmative vote of at least two-thirds of the
voting  rights  and  the  absolute  majority  of  the  par  value  of  the  shares,  each  as  represented  at  a  general  meeting  to
approve, among other things, the following matters:

● the amendment to or the modification of the purpose clause in our Articles of Association;

● a reverse stock split;

● the creation or cancellation of shares with privileged voting rights;

● the restriction on the transferability of shares or cancellation thereof;

● the restriction on the exercise of the right to vote or the cancellation thereof;

● the introduction of or the amendment to a capital band or conditional share capital;

7

● the change of currency of our share capital;

● the delisting of our shares from a stock exchange;

● an increase in the share capital through (1) the conversion of capital surplus, (2) a contribution in kind, or for

purposes of an acquisition of assets, or (3) a grant of special privileges;

● the limitation on or withdrawal of preemptive rights;

● a change in our registered office;

● the conversion of registered shares into bearer shares and vice versa;

● the introduction of an arbitration agreement in our Articles of Association; and

● our dissolution.

The  same  qualified  voting  requirements  apply  to  resolutions  in  relation  to  transactions  among  corporations
based on Switzerland’s Federal Act on Mergers, Demergers, Transformations and the Transfer of Assets and Liabilities
(the  “Merger  Act”),  including  a  merger,  demerger  or  conversion  of  a  corporation  (other  than  a  cash-out  or  certain
squeeze-out mergers, in which minority shareholders of the company being acquired may be compensated in a form
other than through shares of the acquiring company, for instance, through cash or securities of a parent company of the
acquiring company or of another company—in such a merger, an affirmative vote of 90% of the outstanding shares is
required).  Swiss  law  may  also  impose  this  qualified  voting  requirement  in  connection  with  the  sale  of  “all  or
substantially all of our assets” by us. See “—Compulsory Acquisitions; Appraisal Rights” below.

Our Articles of Association require the affirmative vote of at least two-thirds of the shares entitled to vote at a

general meeting to approve the following matters:

● the removal of a serving member of the board of directors;

● any changes to Article 14, paragraph 1 specifying advance notice of proposal requirements;

● any changes to Article 18 specifying vote requirements for resolutions and elections;

● any changes to Article 20, paragraph 2 specifying qualified vote requirements;

● any changes to Article 21 specifying quorum requirements;

● any changes to Article 22 specifying the number of members of the board of directors;

● any changes to Article 23 specifying the term of the board of directors; and

● any  changes  to  Article  24  specifying  the  organization  of  the  board  of  directors  and  the  indemnification

provisions for directors and officers.

Our Articles of Association require the affirmative vote of holders of the number of our shares at least equal
to the sum of (A) two-thirds of the number of all shares outstanding and entitled to vote at a general meeting, plus (B)
a number of shares outstanding and entitled to vote at the general meeting that is equal to one-third of the number of
shares held by an interested shareholder, for us to engage in any business combination with an interested shareholder
(as those terms are defined in our Articles of Association) and for the amendment of the provisions in our Articles of
Association relating to this shareholder approval requirement.

Quorum for General Meetings

The presence of shareholders, in person or by proxy, holding at least a majority of the shares entitled to vote

at the time when the general meeting proceeds to business is generally the required presence for a quorum for the

8

transaction of business at a general meeting of shareholders. However, the presence of shareholders, in person or by
proxy, holding at least two-thirds of the share capital recorded in the commercial register at the time when the general
meeting proceeds to business is the required presence for a quorum to adopt a resolution to amend, vary, suspend the
operation of or cause any of the following provisions of our Articles of Association to cease to apply:

● Article 18—which relates to proceedings and procedures at general meetings;

● Article 19(j)—which relates to business combinations with interested shareholders;

● Article 20—which sets forth the level of shareholder approval required for certain matters;

● Article  21—which  sets  forth  the  quorum  at  a  general  meeting  required  for  certain  matters,  including  the

removal of a serving member of the board of directors; and

● Articles 22, 23 and 24—which relate to the size and the organization of the board of directors, the term of

directors and the indemnification provisions for directors and officers.

Additionally,  shareholders  present,  in  person  or  by  proxy,  holding  at  least  two-thirds  of  the  share  capital
recorded in the commercial register at the time when the general meeting proceeds to business constitute the required
presence for a quorum at a general meeting to adopt a resolution to remove a serving director.

Under the Swiss Code, the board of directors has no authority to waive quorum requirements stipulated in the

articles of association.

Inspection of Books and Records

Under the Swiss Code, a shareholder has a right to inspect the share register with regard to his, her or its own
shares and otherwise to the extent necessary to exercise his, her or its shareholder rights. No other person has a right to
inspect the share register. Shareholders who hold, alone or together, shares representing at least 5% of the share capital
or  the  votes  may  request  to  inspect  our  books  and  records.  Subject  to  safeguarding  business  secrets  or  other  of  our
material interests, our board of directors may authorize such inspection to the extent necessary to exercise shareholder
rights within four months following receipt of such requests.  At a general meeting of shareholders, any shareholder is
entitled to request information from the board of directors concerning the affairs of the company. Shareholders may
also ask the auditor questions regarding its audit of the company. The board of directors and the auditor must answer
shareholders’  questions  to  the  extent  necessary  for  the  exercise  of  shareholder  rights  and  subject  to  safeguarding
business secrets or other of our material interests.

Special Investigation

If  the  shareholders’  inspection  and  information  rights  as  outlined  above  prove  to  be  insufficient,  any
shareholder may propose to the general meeting of shareholders that a special independent commissioner investigate
specific  facts  in  a  special  investigation.  If  the  general  meeting  of  shareholders  approves  the  proposal,  we  or  any
shareholder may, within 30 calendar days after the general meeting of shareholders, request the court at our registered
office to appoint a special independent commissioner. If the general meeting of shareholders rejects the request, one or
more shareholders representing at least 5% of the share capital or the votes may request, within three months after the
general  meeting,  the  court  to  appoint  a  special  independent  commissioner.  The  court  will  issue  such  an  order  if  the
petitioners can demonstrate prima facie that the board of directors, any member of our board of directors or one of our
officers  infringed  the  law  or  our  Articles  of  Association  and  such  infringements  are  capable  of  causing  damage  the
company or the shareholders. The costs of the investigation would generally be allocated to us and only in exceptional
cases to the petitioners.

Compulsory Acquisitions; Appraisal Rights

Swiss  companies  that  undertake  business  combinations  and  other  transactions  that  are  binding  on  all
shareholders are governed by the Merger Act. A statutory merger or demerger requires that at least two-thirds of the
votes  and  the  absolute  majority  of  the  par  value  of  the  shares,  each  as  represented  at  the  general  meeting  of
shareholders, vote in favor of the transaction. Under the Merger Act, a “demerger” may take two forms:

● a legal entity may divide all of its assets and transfer such assets to other legal entities, with the shareholders
of  the  transferring  entity  receiving  equity  securities  in  the  acquiring  entities  and  the  transferring  entity
dissolving upon deregistration in the commercial register; or

● a  legal  entity  may  transfer  all  or  a  portion  of  its  assets  to  other  legal  entities,  with  the  shareholders  of  the

transferring entity receiving equity securities in the acquiring entities.

If  a  transaction  under  the  Merger  Act  receives  all  of  the  necessary  consents,  all  shareholders  would  be

compelled to participate in the transaction. See “—Voting” above.

Swiss  companies  may  be  acquired  by  an  acquirer  through  the  direct  acquisition  of  the  share  capital  of  the
Swiss company. With respect to corporations limited by shares, such as Transocean, the Merger Act provides for the
possibility of a so-called “cash-out” or “squeeze-out” merger if the acquirer controls 90% of the outstanding shares. In
these  limited  circumstances,  minority  shareholders  of  the  company  being  acquired  may  be  compensated  in  a  form
other than through shares of the acquiring company (for instance, through cash or securities of a parent company of the
acquiring company or of another company). For business combinations effected in the form of a statutory merger or
demerger  and  subject  to  Swiss  law,  the  Merger  Act  provides  that  if  the  equity  rights  have  not  been  adequately
preserved  or  compensation  payments  in  the  transaction  are  unreasonable,  a  shareholder  may  request  the  competent
court to determine a reasonable amount of compensation.

In addition, under Swiss law, the sale of “all or substantially all of our assets” by us may require a resolution
of the general meeting of shareholders passed by holders of at least two-thirds of the votes and the absolute majority of
the par value of the shares, each as represented at the general meeting of shareholders. Whether or not a shareholder
resolution is required depends on the particular transaction, including whether the following test is satisfied:

● the company sells a core part of its business, without which it is economically impracticable or unreasonable

to continue to operate the remaining business;

● the  company’s  assets,  after  the  divestment,  are  not  invested  in  accordance  with  the  company’s  statutory

business purpose; and

● the proceeds of the divestment are not earmarked for reinvestment in accordance with the company’s business
purpose but, instead, are intended for distribution to shareholders or for financial investments unrelated to the
company’s business.

If all of the foregoing apply, a shareholder resolution would likely be required.

Corporate Purpose

Transocean  Ltd.  is  the  parent  holding  company  of  the  Transocean  group.  Pursuant  to  its  Articles  of
Association,  its  business  purpose  is  to  acquire,  hold,  manage,  exploit  and  sell,  whether  directly  or  indirectly,
participations  in  businesses  in  Switzerland  and  elsewhere,  in  particular  in  businesses  that  are  involved  in  offshore
contract drilling services for oil and gas wells, oil and gas drilling management services, drilling engineering services

Duration and Liquidation

Our Articles of Association do not limit our duration. Under Swiss law, we may be dissolved at any time by a
resolution adopted at a general meeting of shareholders, which must be passed by the affirmative vote of holders of at
least two thirds of votes and the absolute majority of the par value of the shares, each as represented (in person or by
proxy) at the general meeting. Dissolution and liquidation by court order is possible if (1) we become bankrupt or (2)
shareholders  holding  at  least  10%  of  our  share  capital  so  request  for  valid  reasons.  Under  Swiss  law,  any  surplus
arising out of liquidation (after the settlement of all claims of all creditors) is distributed in proportion to the paid-up
par value of shares held. The amount exceeding the par value of the share is subject to Swiss withholding tax of 35%.
Our shares carry no privilege with respect to such liquidation surplus.

Uncertificated Shares

Our  shares  have  been  issued  in  uncertificated  form  in  accordance  with  article  973c  of  the  Swiss  Code  as
uncertificated  securities,  which  have  been  registered  with  Computershare,  and  constitute  intermediated  securities
within the meaning of the Swiss Federal Act on Intermediated Securities. In accordance with article 973c of the Code,
Transocean Ltd. maintains a register of uncertificated securities (Wertrechtebuch).

Stock Exchange Listing

Our shares are listed and trade on the New York Stock Exchange under the symbol “RIG.”

No Sinking Fund

The shares have no sinking fund provisions.

No Liability for Further Calls or Assessments

The shares that have been issued to date are duly and validly issued, fully paid and non-assessable.

No Redemption and Conversion

The shares are not convertible into shares of any other class or series or subject to redemption either by us or

the holder of the shares.

Transfer and Registration of Shares

We have not imposed any restrictions applicable to the transfer of our shares, other than the requirement that
an acquirer of shares expressly declares to have acquired the shares in its own name and for its own account. Our share
register  is  maintained  by  Computershare,  which  acts  as  transfer  agent  and  registrar.  The  share  register  reflects  only
record owners of our shares. Swiss law does not recognize fractional share interests.

4. Recovery of Erroneously Awarded Compensation.

a.  The  Chief  Financial  Officer  of  the  Company  shall  promptly  report  to  the

Board any instance in which the Company is required to prepare a Restatement.

b.  Upon  learning  of  a  required  Restatement,  the  Board  shall  determine  the

Restatement Date.

c.  The  Chief  Financial  Officer  (or  another  appropriate  officer  or  third  party
designated by the Administrator) shall promptly calculate the Erroneously Awarded
Compensation  for  each  affected  individual,  which  calculation  shall  be  subject  to
approval by the Administrator.    For  purposes  of  calculating  Erroneously  Awarded
Compensation:

i.

Incentive-based  Compensation  shall  be  deemed  received  in  the
Company’s  fiscal  period  during  which  the  Financial  Reporting
Measure  specified  in  the  Incentive-based  Compensation  award  is
attained,  even  if  the  payment  or  grant  of  the  Incentive-based
Compensation  occurs  after  the  end  of  that  period  (but  shall  not
include grants or payments made prior to the Effective Date).

ii. For Incentive-based Compensation based on (or derived from) stock
price  or  total  shareholder  return,  where  the  amount  of  Erroneously
Awarded Compensation is not subject to mathematical recalculation
directly from the information in a Restatement, it shall be based on a
reasonable  estimate  of  the  effect  of  the  Restatement  on  the  stock
price  or  total  shareholder  return  upon  which  the  Incentive-based
Compensation  was 
received.  The  Company  shall  maintain
documentation of the determination of that reasonable estimate and
provide such documentation to the NYSE.

d. Promptly following the Administrator’s approval of the Erroneously Awarded
Compensation,  the  Administrator  shall  notify  in  writing  each  individual  who
received Erroneously Awarded Compensation and shall demand payment or return,
as applicable, of such Erroneously Award Compensation.

3

e.  The  Company  shall  demand  recovery  and  recover  Erroneously  Awarded
Compensation  in  compliance  with  this  Policy  except  to  the  extent  that  the
Administrator  determines  that  recovery  would  be  impracticable,  and  one  of  the
following conditions applies:

i.

ii.

the  direct  expense  paid  to  a  third  party  to  assist  in  enforcing  this
Policy  would  exceed  the  amount  to  be  recovered;  provided,
however,  that  before  concluding  that  it  would  be  impracticable  to
recover  any  amount  of  Erroneously  Awarded  Compensation  based
on  expense  of  enforcement,  the  Company  must  make  a  reasonable
attempt  to  recover  such  Erroneously  Awarded  Compensation,
document  such  reasonable  attempt(s)  to  recover,  and  provide  that
documentation to the NYSE;

recovery  would  violate  home  country  law  where  that  law  was
adopted prior to November 28, 2022; provided, however, that  before
concluding that it would be impracticable to recover any amount of
Erroneously  Awarded  Compensation  based  on  violation  of  home
country law, the Company must obtain an opinion of home country
counsel, acceptable to the NYSE, that recovery would result in such
a violation, and must provide such opinion to the NYSE; or

iii.

recovery  would  likely  cause  an  otherwise  tax-qualified  retirement
plan, under which benefits are broadly available to employees of the
Company, to fail to meet the requirements of Sections 401(a)(13) or
  411(a)  of  the  Internal  Revenue  Code  of  1986,  as  amended,  and
regulations thereunder.

f. Except as provided in Section 4(e)(i), Section 4(e)(ii) or Section 4(e)(iii), in
no event may the Company accept final repayment from the affected individual of
less  than  the  full  amount  of  the  Erroneously  Awarded  Compensation  received  by
such individual.

g.  The  Administrator  shall  determine,  in  its  sole  discretion,  the  method  of
recovering any Erroneously Awarded Compensation pursuant to this Policy, taking
into account all facts and circumstances (including the time value of money and the
cost to shareholders of delayed recovery), so long as such method complies with the
terms  of  Section  303A.14  of  the  NYSE  Listed  Company  Manual.    If  the
Administrator determines that an appropriate method of recovery is one other than
the prompt repayment by the affected individual in cash or property, the Company
may  offer  to  enter  into  a  repayment  agreement  with  the  affected  individual  (in  a
form  and  with  terms  reasonably  acceptable  to  the  Administrator).  The  Company
may  offset,  or  cause  to  be  offset,  any  amounts  that  the  affected  individual  is
required  to  repay  to  the  Company  pursuant  to  this  Policy  against  any  amounts
otherwise owed by the Company or any of its subsidiaries to the affected individual.

4

h.  If  the  affected  individual  fails  to  repay  to  the  Company  when  due  the  full
amount  of  the  Erroneously  Awarded  Compensation  received  by  such  affected
individual, the Company shall take all actions reasonable and appropriate to recover

term  of  similar  meaning)  under  any  employment  or  compensation  arrangements,
agreements, plans or programs.
