November 10, 2021

Dear Noble team members:

Today, we announced that Noble Corporation and Maersk Drilling have entered into a definitive business combination agreement. This exciting announcement creates a leading drilling contractor with attractive scale and diversification across asset classes, geographic regions and basins. It will boast a modern, high-end fleet comprising 20 floaters and 19 jack-up rigs across benign and harsh environments serving a diversified portfolio of great customers. A few other highlights of the transaction include:

• Ownership of combined company will be split 50/50 between Noble and Maersk Drilling shareholders

• Combined company will be named Noble Corporation with headquarters in Houston, and I will serve as CEO

• Charles M. (Chuck) Sledge will become chairman of the Board of Directors

• Creates the youngest and highest specification floater and jackup fleet

• Upholds shared commitment to safety and operational excellence

• Expands customer relationships and geographic footprint

• Ensures financial stability through a solid balance sheet

The combination of Noble and Maersk Drilling brings together two industry leading brands with strong operational platforms and complimentary cultures sharing common values in prioritizing our people, providing best-in-class capabilities, leading safety processes, and operational excellence.

Noble and Maersk Drilling will continue to operate business normally as separate companies until the transaction closes. The transaction is expected to close in mid-2022 at which time our leadership team will be working to integrate the two companies as quickly as practical. All Noble employees should remain focused on our operations. It is your daily efforts expended toward operational excellence and the associated results that make exciting growth opportunities like this possible for the company.

Noble Corporation is a Cayman Islands exempted company with limited liability with company number MC-368504 and registered office at

P.O. Box 309, Ugland House, S. Church Street, Grand Cayman KY1-1104, Cayman Islands

I know you will have additional questions about this transaction, and our intent is to be as open and transparent as possible. The press release found on the Noble website (www.noblecorp.com/investors/news/) provides some further details, including call-in details for an investor call. I invite you to join that call to hear the leaders of both companies explain the strategic rationale and benefits of this historic combination.

Throughout the process, I will continue to provide information on the transaction through various communications including the podcast. If you have any questions that are not covered in the attached Q&As, please email inquiries@noblecorp.com.

The most important goal of every day is to keep our employees and our environment SAFE, while delivering operational excellence as we do every day.

Sincerely,

Questions & Answers

November 10, 2021

As part of our commitment to be open and transparent with our communications throughout the transaction, we have provided anticipated questions and answers below.

In some cases, we are too early in the process to answer all questions but remain committed to sharing information with you as soon as it becomes available.

Q: When do you expect the integration process to be fully completed?

A: We anticipate the two companies will be fully integrated within two years following completion of the transaction.

Q: The HQ of the combined company will be in Texas, and the Noble CEO will take over as CEO for the combined company. Will there be any Maersk Drilling people in the executive management team of the combined company?

A: We will evaluate talent from each organization for selected positions within the leadership team of the combined company.

Q: What will be the name of the combined company?

A: The combined company will be named Noble Corporation.

Q: Will all offshore employees be retained to operate the rigs?

A: To maintain our high level of utilization, safety performance, and customer satisfaction, offshore-based employees will have the opportunity to be retained following the completion of the transaction.

Q: When will employees know whether they still have a job?

A: Employee selection decisions will be announced in a phased approach with planned executive leadership announced prior to completion and the full organization announced after transaction completion. There will be no workforce reductions related to the combination before transaction completion. Following the completion of the transaction, we expect there will be some workforce reductions as a result of integration to achieve our cost synergy targets. Nevertheless, we anticipate longer-term employment opportunity growth because this transaction better positions both companies strategically and financially to pursue growth in ways that would not be achievable on a stand-alone basis.

Q: What can I say publicly about this transaction?

A: Your best response is to refer inquiries to publicly available information, such as the Noble website and press releases. Prior to making any public statements, employees should refer to the Public Relations and Communications Policy in P2R or speak with line management for guidance.

Q: Where will employees be located?

A: The combined entity will operate in global office locations with three main operational regions – Western Hemisphere Benign, Eastern Hemisphere Benign, and the Harsh Environment – and satellite operational hubs across the globe. Employees will remain at their existing work locations, unless otherwise communicated. As part of on-going initiatives or integration planning, any modifications to work locations will be communicated following the completion of the transaction or as information becomes available.

Q: How do I stay updated on the latest information as it becomes available?

A: Please be sure that both your personal and your business (if applicable) email addresses are updated in Workday or with HR for the most efficient communication. The latest information will be posted and maintained on the Announcement Page on the intranet and periodic updates will also be posted in Workday.

Q: Who do I speak with regarding the additional questions I have?

A: We expect that you will have questions that are not answered here, and that new questions will come to light as the transaction process progresses. To make sure we are addressing what is most important to you, please send your questions to inquiries@noblecorp.com. Please note that we may not be able to answer all questions at this point, and that some information will be confidential due to the strict financial disclosure rules that we must comply with during this process.
