Proxy Statement & Notice of Annua Meeting



A Message from Charles M. Sledge, our Board Chair

Dear Fellow Shareholders,

On behalf of the entire Board of Directors (the "Board") of Noble Corporation plc (the "Company" or "Noble"), we invite you to attend our 2026 Annual General Meeting on Wednesday, April 29, 2026. 2025 marked further exciting growth for the Company with the completed integration of Diamond Offshore Drilling, Inc. ("Diamond Offshore") and a notably strong year of commercial wins enhancing our backlog and our industry leadership position. Through our comprehensive strategic fleet transformation - formed by landmark M&A transactions (Diamond 2024, Maersk Drilling 2022, Pacific Drilling 2021), as well as the prudent retirement of cold stacked equipment and disposal of non-core jackups - Noble has become a market leader in high specification deepwater and ultra-harsh environment rigs. To underscore the sweeping extent of this transformation, 24 of the 29 rigs (excluding two rigs held for sale) in our fleet today have come via strategic acquisitions since 2021.

While our strategic activities have been vigorous, the men and women of Noble have maintained uncompromising standards of HSE, operational excellence and financial performance. In the face of cyclical oil market headwinds and softening offshore drilling market conditions in 2025, Noble generated yearly growth in adjusted EBITDA and significant yearly improvement in free cash flow. Additionally, we achieved a highly differentiated 15% yearly increase in contract backlog during 2025 ($7.0 billion at 12/31/2025 vs. $6.1 billion at 12/31/2024) amid a backdrop of broader industry backlog decline. These achievements are a strong testament to the success of our First Choice Offshore efforts across the organization.

While overall contracting activity industry-wide remains relatively subdued compared to the recent record levels witnessed in 2022-2023, there are emerging signs of improving industry utilization at the outset of 2026. Over the medium to longer term, as the world continues to rely on offshore and deepwater hydrocarbon production as a critical energy source, we believe in a positive fundamental outlook for our industry and Noble's strong competitive position.

Executing on our Strategy

Noble remains committed to our First Choice Offshore ambition for employees, customers and shareholders. Our intentional and selective fleet optimization strategy - driven by M&A and refined by non-core asset disposals - has formed a fleet of high specification deepwater and ultra-harsh environment offshore rigs which represents one of the most modern, capable, and highly utilized fleets in the industry.

Our customer and workforce strategy are founded upon Noble's exceptional organizational strength and culture which have been enriched by the integration and onboarding of world class talent and best practices from our recent strategic combinations. We seek to empower and develop our highly talented and committed employees around the world to build meaningful careers and to align themselves with the success of Noble and our customers. We pursue and incentivize exacting standards for HSE, innovation and efficiency in order to manage our customers' most technically challenging and high-risk operations with unwavering reliability. It is this reliability that ultimately drives our commercial success over the long run.

Our First Choice Offshore proposition for shareholders rests on a straightforward financial strategy: to maintain a sound balance sheet and maximize equity value by generating and returning free cash flow to shareholders via dividends and share repurchases. During calendar year 2025, Noble executed on this financial strategy by distributing $320 million in dividends (following $278 million in 2024) and returning an additional $20 million via share repurchases (following $300 million in 2024).

Board Composition is a Key Asset

Our Board reflects the diverse background and perspectives from the legacy Noble, Maersk Drilling and Diamond Offshore boardrooms, as further complemented and enhanced by the addition of the skillsets and experiences brought by the proposed addition of Erik Bergöö, a director nominee standing for election at the 2026 Annual General Meeting of the Company, and H. Keith Jennings, who joined in 2023. Our highly qualified directors are deeply engaged and committed to Noble's success, with each director offering unique and critical expertise from a range of energy and external industrial and public sector settings. Importantly, the strategic planning and execution of our successive business integrations have been greatly enhanced by the collaborative efforts and leadership of this group. I am grateful to each of our directors for their invaluable contributions and ask for your support for all nominees on this year's ballot.

A message from Charles M. Sledge, our Board Chair

Ongoing Commitment to Shareholder Engagement

Maintaining an active, open dialogue with our shareholders continues to be a top priority of the Board. Over the past year, in addition to investor conferences and non-deal roadshows, we have reached out to shareholders representing 61% of our outstanding shares as part of our seasonal shareholder outreach in order to solicit feedback on governance topics, Executive Compensation Program and our previous proxy statement, and members of our Board and management team had the pleasure of meeting with shareholders representing approximately 44% of our shares as part of this outreach initiative. These discussions have spanned a wide variety of topics, including capital allocation, governance, sustainability initiatives, our strategy for growth and long-term value creation and compensation matters such as selection of performance metrics. Shareholder concerns and advice on these and other topics are vital to our planning, and we remain committed to an open dialogue with shareholders in order to maximize value for the Company.

On behalf of the full Board, we thank you for your continued support and investment in the Company. We encourage you to vote for the proposals set forth in this proxy statement.

Sincerely,

Charles M. Sledge

Chairman of the Board of Directors

Explanatory Note

As discussed in greater detail below, we have undertaken corporate actions and entered transactions that have affected our corporate structure. As a result, Noble is a successor issuer to Noble Cayman (as defined below), which is itself a successor issuer to Legacy Noble (as defined below). As used in this proxy statement, when discussing time periods including and after the Effective Date of the Business Combination (each as defined below), the terms "we," "us," "our," and the "Company" refer to Noble and, as appropriate, its subsidiaries, the terms "Board" and "Compensation Committee" refer to the board of directors of Noble and the compensation committee of the board of directors of Noble, and the terms "share," "shares," or "shareholders" refer to Noble's class A ordinary shares ("Ordinary Shares") and shareholders.

When discussing time periods prior to the Effective Date of the Business Combination (each as defined below), the terms "we," "us," "our," and the "Company" refer to Noble Cayman and, as appropriate, its subsidiaries, the terms "Board of Directors" and "Compensation Committee" refer to the board of directors of Noble Cayman and the compensation committee of the board of directors of Noble Cayman, and the terms "share," "shares," or "shareholders" refer to Noble Cayman's ordinary shares and shareholders; provided that to the extent we discuss periods prior to February 5, 2021, the terms "we," "us," "our," and the "Company" refer to Legacy Noble and, as appropriate, its subsidiaries, the terms "Board of Directors" and "compensation committee" refer to the board of directors of Legacy Noble and the compensation committee of the board of directors of Legacy Noble, and the terms "share," "shares," or "shareholders" refer to Legacy Noble's ordinary shares and shareholders.

Emergence from bankruptcy in 2021. On July 31, 2020, our former parent company, Noble Holding Corporation plc (formerly known as Noble Corporation plc), a public limited company incorporated under the laws of England and Wales ("Legacy Noble"), and certain of its subsidiaries filed voluntary petitions in the United States Bankruptcy Court for the Southern District of Texas seeking relief under chapter 11 of title 11 of the United States Code. In connection with these chapter 11 proceedings, on and prior to the Emergence Date (as defined below), Legacy Noble and certain of its subsidiaries effected certain restructuring transactions pursuant to which Legacy Noble formed Noble Corporation, an exempted company incorporated in the Cayman Islands with limited liability ("Noble Cayman"), as an indirect wholly-owned subsidiary of Legacy Noble and transferred to Noble Cayman substantially all of the subsidiaries and other assets of Legacy Noble. On February 5, 2021 (the "Emergence Date"), Noble Cayman and its subsidiaries emerged from the chapter 11 proceedings, and Noble Cayman became the new parent company.

Business Combination with Maersk Drilling in 2022. On September 30, 2022 (the "Effective Date"), as a result of certain intercompany transactions relating to the Business Combination (as defined below), Noble became the ultimate parent of Noble Cayman and its respective subsidiaries, and the Ordinary Shares of Noble began trading on the New York Stock Exchange (the "NYSE") under the symbol "NE." On October 3, 2022 (the "Closing Date"), Noble completed a voluntary tender exchange offer to the shareholders of The Drilling Company of 1972 A/S, a Danish public limited liability company ("Maersk Drilling") (the "Offer" and, together with other transactions, the "Business Combination"). Upon consummation of the Offer, because Noble had acquired more than 90% of the issued and outstanding shares of Maersk Drilling, Noble redeemed all remaining Maersk Drilling shares not exchanged in the Offer under Danish law by way of a compulsory purchase (the "Compulsory Purchase"). Upon completion of the Compulsory Purchase, Maersk Drilling became a wholly owned subsidiary of Noble.

Acquisition of Diamond Offshore Drilling in 2024. On June 9, 2024, Noble entered into an agreement and plan of merger (the "Diamond Merger Agreement") with Diamond Offshore Drilling, Inc. ("Diamond"), Dolphin Merger Sub 1, Inc., and Dolphin Merger Sub 2, Inc., under which Noble would acquire Diamond in a stock plus cash transaction (the "Diamond Transaction"). On September 4, 2024, Noble completed its acquisition of Diamond. Pursuant to the terms and conditions set forth in the Diamond Merger Agreement, Diamond shareholders received 0.2316 shares of Noble, plus cash consideration of $5.65 per share for each share of Diamond.

‌About Noble

Noble Corporation plc ("Noble") is a leading offshore drilling contractor for the oil and gas industry. We provide contract drilling services to the international oil and gas industry with our global fleet of mobile offshore drilling units. We focus on a high-specification fleet of floating and jackup rigs and the deployment of our drilling rigs in oil and gas basins around the world. Noble and its predecessors have been engaged in the contract drilling of oil and gas wells since 1921. As of the date of this proxy statement, our fleet of 31 drilling rigs consisted of 25 floaters and 6 jackups.



‌Business Strategy



Mission Vision

Our mission is Drilling to Power the World Responsibly.

We strive to be the leading offshore driller by being the first choice for employees, customers and investors.

Our business strategy is centered around providing efficient, reliable and safe offshore drilling services to our customers. Our strategic initiatives over the past five years have created one of the highest specification fleets in the industry, with global scale and diversification and industry-leading backlog.

Our fleet consists predominately of technologically advanced units, equipped with sophisticated systems and components prepared to execute our customers' increasingly complicated offshore drilling programs safely and with greater efficiency. We are primarily focused on the ultra-deepwater market and the ultra-harsh environment jackup markets, which typically are more technically challenging markets in which to operate.

We emphasize safe operations, environmental stewardship, and superior performance through a structured management system, the employment of qualified and well-trained crews and onshore support staff, the care of our surroundings and the neighboring communities where we operate, and other activities advancing our sustainability, social responsibility, and good governance. We also manage rig operating costs through the implementation and ongoing improvement of innovative systems and processes, which includes the use of data analytics and predictive maintenance technology.

Our organization prioritizes financial discipline, cash flow generation and returning cash to shareholders. Management plans to continue to evaluate our balance sheet and focus on enabling our fleet of floating and jackup rigs to meet the demands of increasingly complex drilling programs required by our customers.

About Noble

We are committed to ongoing improvement and a sustainable energy future, supported by our efforts to protect the environment throughout our operations and safely provide reliable and efficient services to allow access to resources essential for human and economic prosperity. We actively look to collaborate with our customers to evaluate economic alternatives for reducing the carbon footprint of our drilling rigs. Oversight of our sustainability is at the Board level, with the safety and sustainability committee of the Board (the "Safety & Sustainability Committee") assisting in that oversight role with respect to the Company's sustainability policies and practices.

Noble - First Choice Offshore

The Company's strategy has been focused on delivering industry-leading shareholder returns, including executing on, and integrating, inorganic growth opportunities. The Company's performance highlights for 2025 include:

  • Leadership position in shareholder returns in the offshore drilling sector, with $320 million in dividends paid and $20 million of share repurchases.

  • Differentiated Backlog Growth

    • Expanded backlog by 30% year-on-year to $7.5 billion as of February 2026, while the combined backlog of our three largest peers declined by 9% over the comparable period.

    • Significant backlog expansion was underpinned by long-term contract awards for six deepwater rigs with Shell, TotalEnergies and bp throughout the United States Gulf of America and Suriname basins with an average duration of three years per rig.

  • Customer Satisfaction proven by high satisfaction scores (ranging from 6.2 to 6.6 out of 7) from January 1, 2023 through to December 31, 2025 and averaging 6.5 out of 7 in 2025.

  • Seamless operation integration highlighted by 96.9% revenue efficiency and strong Health, Safety and Environment (HSE) performance across the fleet.

‌Sustainability

As a responsible drilling contractor with a comprehensive approach to sustainability, Noble remains committed to building on the Company's strategy of enabling long-term sustainable value creation. Noble's sustainability mission is to help provide affordable energy efficiently, safely and sustainably, by leveraging longstanding customer relationships and unique innovation capabilities. Noble continues leveraging sustainability as a driver of business resilience and value creation, helping to ensure that our approach to sustainability reporting not only meets regulatory expectations but also supports sustainable growth and long-term shareholder returns.

In 2025, in alignment with Noble's First Choice Offshore strategy, we continued to place strong priority on advancing energy efficiency and lowering fuel consumption within our broader sustainability efforts. We anticipate progressing a clear roadmap toward a 20% carbon-intensity reduction by 2030, and we believe these efforts to support customer value and competitive positioning. Taken together, these initiatives are intended to lower well delivery costs and strengthen our competitive differentiation by linking efficiency gains to tangible value for our customers and shareholders.

‌2025 Highlights

In 2025, Noble has progressed on several sustainability initiatives. Highlights for 2025 are listed below according to the Noble's sustainability framework pillars.

SUSTAINABLE ENERGY FUTURE



  • Energy Efficiency Progress

    Noble advanced its energy-efficiency goals by deploying an Energy Management System, expanding real-time digital dash-boards, and accelerating crew-driven initiatives within EnergyWise (i.e., Noble's sustainable behavior program focused on identifying and implementing ways to build energy efficiency operations offshore, officially launched in 2024) to reduce fuel use and energy waste across the fleet.

  • ISO 14001 Achievement

    Noble Stanley Lafosse achieved ISO 14001 certification on its first attempt with zero major nonconformities, advancing Noble's environmental leadership and expanding fleetwide certification efforts.

    CARING FOR PEOPLE



  • Workforce Training Enhancement

    Noble enhanced employee development through LinkedIn Learning, global Learning Lab knowledge-sharing, and Noble Offshore Readiness Training Hub (NORTH) training for over 300 new hires across nine countries.

  • Future Talent Development

    Noble strengthened future talent development through hands-on U.S. and Poland internships and the University of Texas Co-Innovation Challenge, engaging nearly 100 students and generating 15 innovative industry concepts.

    RESPONSIBLE BUSINESS



  • Charitable Giving Governance

    Noble adopted a Charitable Contributions Policy, setting eligibility criteria and approval process under Charitable Contributions Committee oversight to strengthen governance, ensure ethical compliance, and direct funds toward measurable, impact-focused outcomes.

  • Verified GHG Reporting

Noble's 2023-2024 GHG inventory successfully underwent independent verification. Noble is focused on transparent reporting, sustainability and continuous improvement, and its reporting is aligned with recognized reporting criteria.

Beneficial holders of shares (i.e., those who are not shareholders of record but hold shares through a shareholder of record as further described below) are only entitled to instruct their bank, broker, or other holder of record how to vote at the Meeting if they held their book entry interest as at 5:00 p.m. Eastern Time on March 6, 2026. For shareholders of record, the record date in respect of entitlement to notice of, and to attend and vote at, the Meeting will also be 5:00 p.m. Eastern Time on March 6, 2026.

At 5:00 p.m. Eastern Time on the record date, there were 159,473,433 Ordinary Shares of Noble outstanding and entitled to vote at the Meeting. Each Ordinary Share is entitled to one vote.

Procedure to Access Proxy Materials Over the Internet

Your Notice of Internet Availability of Proxy Materials, or (if you received paper copies of the proxy materials) your proxy card or voting instruction form, will contain instructions on how to view our proxy materials on the Internet for the Meeting.

Our proxy materials are also available at www.proxyvote.com and at https://noblecorp.com/2026-Annual-General-meeting.

Shareholders of Record and "Street Name"

Shareholder of Record. If your Ordinary Shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered a "shareholder of record" with respect to those shares, and you are receiving these proxy materials directly from us. As the shareholder of record, you have the right to mail your proxy card directly to us or to vote in person at the Meeting.

Street Name Shareholder. If your shares are held in a stock brokerage account, by a bank or other holder of record (commonly referred to as being held in "street name"), you are the "beneficial owner" with respect to those shares and these proxy materials are being forwarded to you by that custodian.

As a street name holder, you have the right to direct your broker, bank or other nominee how to vote your shares and you are also invited to attend the Meeting. However, since you are not the shareholder of record, you may not vote these shares in person at the Meeting unless you obtain a signed legal proxy from the shareholder of record giving you the right to attend and vote the shares. Should you wish to vote your shares but not attend the Meeting in person, your broker, bank or other nominee has provided voting instructions for you to use in directing the broker, bank or other shareholder of record how to vote your shares. If you fail to provide sufficient instructions to your broker, bank or other shareholder of record, the shareholder of record may be prohibited from voting your shares as discussed elsewhere in this proxy statement.

How to Vote

The Board encourages you to exercise your right to vote. Your vote is important. Beneficial holders can vote by providing a voting instruction to their relevant broker, bank or other shareholder of record on how to vote their shares at the Meeting. Providing your voting instruction means you authorize nominated representatives to vote your shares at the Meeting in the manner you direct.

If you are a shareholder of record (as described above), there are two ways to vote your shares:

  • By Internet-You may vote over the Internet at www.proxyvote.com by following the instructions in the Notice of Internet Availability or, if you received your proxy materials by mail, by following the instructions on the proxy card.

  • By mail-If you received proxy materials by mail, you may appoint a proxy and provide voting instructions by mail by marking, dating, signing, and returning the proxy form in the postage-paid envelope.

    If you are a beneficial holder (as described above), there are generally three ways to vote your shares:

  • By Internet-You may vote over the Internet at www.proxyvote.com by following the instructions in the Notice of Internet Availability or, if you received your proxy materials by mail, by following the instructions on the voting instruction form.

  • By telephone-Street name holders located in the United States that receive proxy materials by mail may vote by telephone by calling 1-800-454-8683 and following the instructions on the voting instruction form.

  • By mail-If you received proxy materials by mail, you may provide voting instructions by mail by marking, dating, signing, and returning the voting instruction form in the postage-paid envelope.

    Appointment of proxies via telephone (for street name holders only) and internet will be available 24 hours a day, and appointment or revocation of proxies will close at 11:59 p.m. Eastern Time on April 27, 2026.

    Appointing a proxy will not limit the right of a shareholder of record to vote at the Meeting if they decide to attend in person. The Board recommends that you appoint a proxy or provide voting instructions because most shareholders do not choose to attend the Meeting in person.

    If you are a beneficial holder, you will receive instructions from the bank, broker or other shareholder of record of your shares. You must follow the instructions of such bank, broker or other shareholder of record in order for your shares to be voted. If such instructions differ from those outlined above, you should follow the instructions provided by the bank, broker or other shareholder of record of your shares. If you attend the Meeting in person, to vote shares held in the name of a bank, broker or other shareholder of record, you must obtain a legal proxy, executed in your favor, from the applicable bank, broker or other shareholder of record to be able to vote at the Meeting.

    Proxy Statement

    The shares represented by all valid proxies received will be voted in the manner specified. Where specific choices are not indicated, the shares represented by all valid proxies will be voted:

    • for the nominees for directors named in Resolutions 1-7;

    • for the resolutions relating to the ratification of the appointment of PricewaterhouseCoopers LLP (US) as the independent registered public accounting firm, the appointment of PricewaterhouseCoopers LLP (UK) as UK statutory auditor, and the authority to set the compensation of PricewaterhouseCoopers LLP (UK) as set forth in Resolutions 8-10;

    • for the approval of the advisory resolutions on executive compensation and director remuneration as set forth in

      Resolutions 11 and 12;

    • for the approval of the directors' remuneration policy as set forth in Resolution 13;

    • for the authorization of the Board to allot shares under section 551 of the UK Companies Act 2006 ("UK Companies Act") as set forth in Resolution 14;

    • for the authorization of the Board to allot shares without rights of pre-emption as set forth in Resolution 15; and

    • if any other matters are properly presented at the Meeting (including any motion to adjourn the Meeting), at the direction of the Chair of the Meeting.

    How to Change Your Vote; Revocability of Proxy

    If you are a shareholder of record, you may later revoke your proxy appointment by:

  • sending a written statement to that effect to the Corporate Secretary at the address listed on page 71 of this proxy statement;

  • appointing a proxy again by the Internet (only the last vote cast and the last proxy appointed will be treated as valid), provided that you do so before 11:59 p.m. Eastern Time on April 27, 2026;

  • submitting a properly signed proxy with a later date; or

  • voting in person at the Meeting.

    If you are a street name holder, you may later revoke your voting instructions by following the procedures provided by your bank, broker or other nominee.

    Quorum

    In order for us to hold our Meeting, holders of a majority of the shares issued and outstanding and entitled to vote at the Meeting must be present in person or by proxy at the Meeting.

    This is referred to as a quorum. Abstentions and "broker non-votes" will be counted as present for purposes of determining a quorum.

    Routine and Non-Routine Matters; Abstentions and Broker Non-Votes

    The New York Stock Exchange ("NYSE") permits brokers to vote their customers' shares held in street name on certain routine matters when the brokers have not received voting instructions from their customers. The NYSE does not, however, allow brokers to vote their customers' shares held in street name on non-routine matters unless they have received voting instructions from their customers. Generally, in such cases, the uninstructed shares that the broker is unable to vote are called "broker non-votes." Even with respect to routine matters, some brokers are choosing not to exercise discretionary voting authority. As a result, we urge you to direct the bank, broker or other shareholder of record that holds your shares how to vote your shares on all proposals to ensure that your vote is counted.

    Abstentions and "broker non-votes," to the extent any, will be considered as present for quorum purposes, but will not be considered as votes cast and, thus, will not be counted in the votes "for" or "against" a resolution.

    Vote Required for Each Resolution

    Subject to disenfranchisement in accordance with applicable law and/or the Company's Articles of Association, each of the resolutions shall be decided on a poll in accordance with the Company's Articles of Association whereby each shareholder of record present in person or by proxy is entitled to one vote for every share held.

    Approval of all resolutions, except for Resolution 15, requires the affirmative vote of a simple majority of the votes cast on such resolution at the Meeting in person or by proxy. With respect to the non-binding advisory votes on Resolutions 11 and 12, the Board values the opinions of the Company's shareholders as expressed through their advisory votes on such non-binding resolutions. Accordingly, the Board will review and consider the voting results on such resolutions.

    Resolution 15 will be proposed as a special resolution and requires the affirmative vote of at least 75% of the votes cast, whether in person or by proxy, at the Meeting on Resolution 15.

    Abstentions and "broker non-votes," to the extent any, have no effect on any of the resolutions and will not be counted in the votes "for" or "against" a resolution.

    Proxy Solicitation

    Noble is making this solicitation and will pay the entire cost of preparing, assembling, printing, mailing, and distributing the notices and these proxy materials and soliciting votes. In addition to sending you these materials or otherwise providing you access to these materials, some of our directors and officers as well as management and non-management employees may contact you by telephone, mail, e-mail, or in person. You may also be solicited by means of press releases issued by the Company, postings on our website at https://www.noblecorp.com, advertisements in periodicals, or other media forms. None of our officers or employees will receive any extra compensation for soliciting you. We will also reimburse banks, nominees, fiduciaries, brokers, and other custodians for their costs of sending the proxy materials to the beneficial owners of our shares. In addition, to assist us with our solicitation efforts, we have retained the services of Georgeson for a fee of approximately $17,500, plus out-of-pocket expenses.

    Tabulation

    Representatives of Broadridge will tabulate and certify the vote at the Meeting.

    Results of the Vote

    We will announce the preliminary voting results at the Meeting and disclose the final voting results in a current report on Form 8-K filed with the SEC within four business days of the date of the Meeting unless only preliminary voting results are available at the time of filing the Form 8-K, in which case, to the extent necessary, we will file an amended report on Form 8-K to disclose the final voting results within four business days after the final voting results are known. You may access or obtain a copy of these and other reports free of charge on the Company's website at www.noblecorp.com. Also, the referenced Form 8-K, any amendments thereto and other reports we file with the SEC are available to you over the Internet at the SEC's website at www.sec.gov. Additionally we will announce final results of the Meeting and publish them on our website.

    Householding

    We participate, and some brokers, banks, trustees, custodians, and other nominees may be participating, in the practice of "householding" proxy materials. This procedure allows multiple shareholders residing at the same address the convenience of receiving a single proxy statement and Annual Report on Form 10-K and Notice of Internet Availability. If you receive a single set of proxy materials as a result of householding and you would like to have separate copies of our proxy statement and Annual Report on Form 10-K or Notice of Internet Availability mailed to you, please submit a request to imacpherson@noblecorp.com or call our Investor Relations department at 713-239-6019, and we will promptly send you the requested materials. You can also contact our Investor Relations department if you received multiple copies of the proxy materials and would prefer to receive a single copy in the future, or if you would like to opt out of householding for future mailings.

    If shareholders received one set of materials due to householding, they may revoke their consent for future mailings at any time by contacting Broadridge via:

  • Phone Number: 1-866-540-7095.

  • Mail: Broadridge Householding department, 51 Mercedes way, Edgewood, NY, 11717.

    Summary of Director Nominee Skills, Experience and Characteristics

    The director skills matrix assists the Board in considering the appropriate balance of experience, skills and attributes required of a director and to be represented on the Board as a whole. The skills matrix was developed after considering the Company's near and long-term strategies and is intended to identify skills and attributes that will assist the Board in exercising its oversight function. The skills matrix assists in determining whether a potential Board member's skills would complement the skills of the current Board members. The matrix is a summary of key skills; it does not include all of the skills, experiences and qualifications that each director nominee offers, and the fact that a particular experience, skill or qualification is not listed does not mean that a director does not possess it.

    Our Board reflects the variety of experiences, perspectives and skillsets of a highly qualified group of professionals, with each director offering unique, critical and complementary expertise from a range of varied sectors relevant to the Company and its business, including, among others, energy and energy exploration, offshore industry, oilfield services, and external industrial settings. The productive engagement and leadership of this group, deeply committed to the Company's success, have fostered collaborative alignment on the Company's key goals and execution against our objectives. While we continuously assess the composition of our Board through our refreshment practices and nomination guidelines, as described in more detail below, we strongly believe that the director nominees reflect the right Board composition to capitalize on the strategic positioning of the Company and deliver against our plans. Among our director nominees, one director is a woman and one director is African American, and the nominees collectively represent four different nationalities.

In addition, we review SEC filings made by beneficial owners of more than five percent of any class of our voting securities to determine whether information relating to transactions with such persons needs to be included in our proxy statement or annual report. There were no related-party transactions in 2025 that were required to be reported pursuant to the applicable disclosure rules of the SEC, except as described herein.

‌Corporate Governance

‌Board Independence

Our Board has determined that:

  • each of Ms. Douglas, Mr. Hemmingsen, Mr. Hirshberg, Ms. Holth, Mr. Jennings, and Mr. Sledge qualifies as an "independent" director under the NYSE corporate governance rules and the Company's corporate governance guidelines.

  • each of Mr. Jennings (Chair), Ms. Douglas, Ms. Holth, and Mr. Sledge, constituting all the members of the audit committee of the Board (the "Audit Committee"), qualifies as "independent" under Rule 10A-3 of the Exchange Act; and

  • each of Mr. Hirshberg (Chair), Ms. Douglas, and Mr. Sledge, constituting all the members of the compensation committee of the Board (the "Compensation Committee"), qualifies as

    • "independent" under Rule 10C-1(b)(1) under the Exchange Act and the applicable rules of the NYSE; and

    • a "non-employee director" for purposes of Rule 16b-3 under the Exchange Act.

      Independent non-management directors comprise in full the membership of each committee described below under "-Board Committees, Meetings and Other Governance Matters."

      Additionally, our Board determined that each of Alastair Maxwell and Ann Pickard qualified as an "independent" director under the NYSE corporate governance rules and the Company's corporate governance guidelines for the portion of 2025 that they served on the Board.

      Mr. Eifler and Mr. Bergöö are not independent.

      In order for a director to be considered independent under the NYSE rules, our Board must affirmatively determine that the director has no material relationship with the Company other than in his or her capacity as a director of the Company.

      The Company's corporate governance guidelines provide that a director will not be independent if,

  • the director is, or during the preceding three years, was employed by the Company;

  • an immediate family member of the director is, or during the preceding three years, was an executive officer of the Company;

  • the director or an immediate family member of the director received, within any 12-month period during the preceding three years, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service);

  • the director is a current partner or employee of the Company's internal or external auditor;

  • an immediate family member of the director is a current partner of the Company's internal or external auditor;

  • an immediate family member of the director is currently employed by the Company's internal or external auditor and personally works on the Company's audit;

  • the director or an immediate family member of the director was, during the preceding three years, a partner or employee of the Company's internal or external auditor and personally worked on the Company's audit within that time;

  • the director or an immediate family member of the director is, or, during the preceding three years was, employed as an executive officer of another company where any of the Company's present executive officers serves or served on that company's Compensation Committee at the same time; or

  • the director currently is an executive officer or an employee, or an immediate family member of the director currently is an executive officer, of a company that made payments to, or received payments from, the Company for property or services in an amount which, in any single fiscal year within the last three fiscal years, exceeded the greater of $1 million or two percent of such other company's consolidated gross revenues.

    Corporate Governance

    The following will not be considered by our Board to be a material relationship that would impair a director's independence: If a director is an executive officer of, or beneficially owns in excess of 10 percent equity interest in, another company

  • that does business with the Company, and the amount of the annual payments to the Company is less than five percent of the annual consolidated gross revenues of the Company;

  • that does business with the Company, and the amount of the annual payments by the Company to such other company is less than five percent of the annual consolidated gross revenues of the Company; or

  • to which the Company was indebted at the end of its last fiscal year in an aggregate amount that is less than five percent of the consolidated assets of the Company.

    For relationships not covered by the guidelines in the immediately preceding paragraph, the determination of whether the relationship is material or not, and therefore whether the director would be independent or not, is made by our directors who satisfy the independence guidelines described above. These independence guidelines used by our Board are set forth in our corporate governance guidelines, which are published under the governance section of the Company's website at https://www.noblecorp.com.

    In addition, in order to be independent for the purposes of serving on the Audit Committee, a director may not, other than in his or her capacity as a member of the Audit Committee, the Board, or any other board committee:

  • accept, directly or indirectly, any consulting, advisory, or other compensatory fee from the Company or one of our subsidiaries (other than certain retirement benefits for prior service with the Company); or

  • be affiliated with the Company, one of our subsidiaries, or an affiliate of one of our subsidiaries.

    Further, in order to determine the independence of any director who will serve on the Compensation Committee, the Board must consider all factors specifically relevant to determining whether a director has a relationship to the Company that is material to that director's ability to be independent from management in connection with the duties of a Compensation Committee member, including, but not limited to:

  • the source of compensation of such director, including any consulting, advisory or other compensatory fee paid by the Company to such director; and

  • whether such director is affiliated with the Company, one of our subsidiaries or an affiliate of one of our subsidiaries.

In accordance with the Company's corporate governance guidelines, the non-management directors have chosen an independent Chair of the Board to preside at regularly scheduled executive sessions of our Board held without management present. Mr. Sledge currently serves as our independent Chair.

‌Board Committees, Meetings and Other Governance Matters

The Company has standing Audit, Compensation, Nominating & Governance, and Safety & Sustainability Committees of our Board. Each of these committees operates under a written charter that has been adopted by the respective committee and by our Board. The charters are published under the governance section of the Company's website at www.noblecorp.com and are available in print to any shareholders who request them. Our Code of Business Ethics is published under the governance section of the Company's website at www.noblecorp.com. We intend to disclose future amendments to certain provisions of the Code of Business Ethics, and waivers of the Code of Business Ethics granted to executive officers and directors, on the website within four business days following the date of the amendment or waiver.

Board Refreshment

We recognize the importance of board refreshment, and the Nominating & Governance Committee regularly considers board composition and how directors change over time. To assist our board refreshment efforts, our corporate governance guidelines provide for a mandatory retirement age of 72, without exception. Further, under the Relationship Agreement entered in connection with the Business Combination, one of our non-management directors has been designated by a former shareholder of Maersk Drilling. See "-Director Designation Rights," above at page 14, for further information on this agreement. At the conclusion of the Business Combination in the fall of 2022 our Board reflected the diverse background and perspectives from each of the legacy Noble and Maersk Drilling boardrooms. In November of 2023, in our first director appointment to the Board since the Business Combination, we appointed H. Keith Jennings. Subsequently, in connection with
