Letter from the Board of Directors
April 4, 2025
Dear Fellow Shareholders,
We invite you to participate in Northrop Grumman Corporation’s 2025 Annual Meeting of Shareholders on Wednesday, May 21, 2025, beginning at 8 a.m. ET. The accompanying Proxy Statement explains more about the matters to be voted on at the Annual Meeting, proxy voting instructions and other information regarding participation.

At Northrop Grumman, we remain steadfast in our mission to deliver cutting-edge technologies and game-changing innovations that are paramount to our national security. More than ever before, the solutions we deliver for our customers help achieve our customers’ goal of peace through strength. We are driven each day to perform at the highest level, knowing that our products and services are contributing to a safer world and brighter future.

We continue to execute our long-term business strategy, creating value for our customers and shareholders. Our strategy is underpinned by maintaining technology leadership, a laser focus on performance, and deploying capital in value creating ways. We’ve invested over $3.5 billion in capex over the past two years to position the Company for future success, while returning $3.7 billion, or over 100% of free cash flow*, to shareholders in 2024.

Proof that our strategy is working is reflected in our strong 2024 financial results. We achieved a new record backlog in 2024 of $91.5 billion, driven by continued strong demand for our products and services. Our annual sales grew by 4.4 percent to $41 billion, and have now increased by 30% organically over the past five years. Strong program performance led to an increase in operating income, and we generated $4.4 billion of operating cash flow with free cash flow* growing by 25 percent to $2.6 billion.

Looking ahead, our team, strategy and culture strengthen our position for the future. With 97,000 of the world’s best problem solvers united around our values, our actions demonstrate to our customers, suppliers and communities, every day, that we uphold our promises, do the right thing and commit to shared success.

With a talented team, robust portfolio and strong business strategy, we are confident we will continue to lead our industry and deliver for our customers and shareholders.

Shareholder Engagement
At Northrop Grumman, we believe that regular, ongoing engagement with our shareholders is a critical component of our corporate governance framework. We have an extensive shareholder outreach program that provides us with important feedback to understand our shareholders’ top priorities. These discussions include members of our leadership team and Board to ensure we stay well-informed regarding our shareholders' views and to provide our shareholders with an opportunity to hear directly from our key leaders.

Our shareholder outreach program is designed to have ongoing engagement with shareholders throughout the year. This includes attending investor conferences, non-deal roadshows, one-on-one meetings, and site visits. In addition, we seek engagement with our largest shareholders twice a year with a focus on corporate governance related topics.

We have a proven record of adopting provisions or modifying practices as a result of shareholder engagement and feedback. For example, in 2023, after considering shareholder inputs and discussions, we submitted a management proposal at our annual meeting to reduce the threshold required to call a special meeting from 25% to 15%. This proposal was overwhelmingly supported by our shareholders with approximately 99% support. We also adjusted our executive compensation program to include Return on Invested Capital* (ROIC) as a component of our long-term financial metrics. We remain committed to robust, ongoing engagement to ensure continued alignment to shareholder interests and priorities.

Proposal 1: Election of Directors
Our Board has nominated 12 directors for election at the Annual Meeting. Mr. Robinson has decided not to seek re-election to the Board at the Annual Meeting. He will conclude his service on the Board immediately following the Annual Meeting. The Board intends to reduce the number of members of the Board from 13 to 12 directors effective with the Annual Meeting. Each of the director nominees has consented to serve, and we do not know of any reason why any of them would be unable to serve, if elected. If a nominee becomes unavailable or unable to serve before the Annual Meeting (for example, due to serious illness), the Board may determine to leave the position vacant, reduce the number of authorized directors or designate a substitute nominee. In the unanticipated event that a nominee becomes unavailable for election to the Board, the proxyholders will have full discretion and authority to vote, or refrain from voting, for any other nominee in accordance with their judgment.
Vote Required
To be elected, a nominee must receive more votes cast “for” than votes cast “against” his or her election. Abstentions and broker non-votes will have no effect on this proposal. If a nominee is not re-elected, he or she will remain in office until a successor is elected or until his or her earlier resignation or removal. See page 26 for additional information on our Director Election Process.

The assessment focuses on achieving a diverse mix of skills and experiences necessary for effective governance and oversight by the Board as a whole, ultimately advancing the long-term interests of our shareholders. The Committee is dedicated to ensuring a talented and well-rounded board, comprised of members with the requisite skills, experience, and commitment to serve the Company and its shareholders. The Committee provides regular updates to the Board regarding the mix of skills and expertise needed in the future, taking into account the evolving needs of the Company and its businesses and upcoming retirements from the Board.
THE COMMITTEE CONSIDERS A RANGE OF CRITERIA WHEN EVALUATING POTENTIAL CANDIDATES
graphic_check(bg).jpg High personal and professional integrity
graphic_check(bg).jpg Relevant educational and professional background and experience
graphic_check(bg).jpg Diverse and complementary skills and experiences relevant to the Company

CANDIDATE EVALUATION
In evaluating candidates, the Nominating and Corporate Governance Committee considers:

the personal integrity and the professional reputation of the individual;
the education, professional background and particular skills and experience most beneficial to service on our Board;
how the nominee brings diverse and complementary skills, experiences and perspectives valuable to the Company and Board at the time;

Proposal 1: Election of Directors
Shareholder Nominations
Shareholders may recommend director candidates for consideration by the Nominating and Corporate Governance Committee pursuant to our Principles of Corporate Governance. The Nominating and Corporate Governance Committee considers such director candidates recommended by shareholders similarly to other potential director candidates brought to the attention of the Nominating and Corporate Governance Committee. Shareholder recommendations for director candidates under our Principles of Corporate Governance must be addressed to the Nominating and Corporate Governance Committee in care of the Corporate Secretary. In addition, and as discussed immediately below, shareholders may also directly nominate director candidates in accordance with our Bylaws.
Proxy Access
Under the Company’s proxy access bylaws, a shareholder, or a group of up to 20 shareholders, that has maintained continuous ownership of 3% or more of the Company’s outstanding common stock for at least three years may include in the Company’s proxy materials director nominees constituting up to the greater of two nominees or nominees constituting 20% of the number of directors in office. Director nominees may receive compensation from third parties for their candidacy, up to the total annual compensation paid to directors of the Company, as well as reimbursement for reasonable expenses, provided there is full disclosure of such compensation. Under the Company’s bylaw provisions, directors are treated similarly, whether nominated through proxy access or otherwise, and held to the same high fiduciary standards to serve all shareholders.
The Company’s Bylaws provide our shareholders with broad and meaningful access to the Company’s proxy materials while enhancing transparency, protecting the interests of all shareholders and ensuring good governance. The terms of the Company's proxy access bylaw provisions are also broadly consistent with other Fortune 500 companies' terms, reflecting best practices.
Director Election Process
Our Bylaws and Certificate of Incorporation provide for the annual election of directors. Each director will hold office until the next annual meeting of shareholders or until his or her earlier resignation or removal. Generally, in order to be elected, a director must receive more votes cast “for” than “against” his or her election, unless one or more shareholders provide notice of an intention to nominate one or more candidates to compete with the Board’s nominees for election in accordance with the procedures set forth in the Company’s corporate governance documents.
Effect of Failure to Obtain and Retain Security Clearance or Receive the Required Vote
Each director is required to tender a resignation in the event of and effective upon the failure to obtain top secret security clearance within 12 months of election or appointment to the Board, or the failure to retain a top secret security clearance once obtained. If an incumbent director fails to obtain and retain a top secret security clearance, the Nominating and Corporate Governance Committee will consider whether the Board should accept the director’s resignation and will submit a recommendation for prompt consideration by the Board. In addition, each director is required to tender a resignation in the event of and effective upon the failure to receive the required vote at any future meeting at which such director faces re-election. The Nominating and Corporate Governance Committee and the Board will consider relevant facts in deciding whether to accept a resignation, including, without limitation, any harm to the Company that may result from accepting the resignation.

Corporate Governance
Risk Oversight

As noted above, the Board is responsible for overseeing risk management, with a focus on both near and long term significant risks to the Company, our business and our strategy. For each significant risk, the Company identifies a senior executive responsible for its management, alongside a designated Board committee (or the full Board) tasked with providing oversight. The Board's governance framework for risk management allows for clear allocation of responsibilities of risk oversight among the full Board and its committees, leveraging the Board's skills and leadership structure. Our risk oversight framework facilitates regular assessments of the Company’s risk management processes and controls and whether they are functioning at maximum effectiveness.

Corporate Governance
Management's Role in Enterprise Risk Management
Our governance framework has been carefully developed to ensure a comprehensive system of oversight and accountability. The Company's management, under the oversight of the Board, executes the Company's risk management strategies and is the first line of defense in identifying emerging risks.

Enterprise Risk Management Council

The Enterprise Risk Management Council (ERMC), comprised of key members of the Company's management team, plays a vital role in reviewing the significant risks to the enterprise and ensuring effective consideration, mitigation, and management. For each significant risk, the Company identifies a senior executive responsible for its management. During meetings of the ERMC, the Council receives updates from each management lead, with particular focus on any significant changes in the risk profile or necessary mitigations for such risk. During its meetings, the Council also discusses risk mitigation strategies, process enhancements and evolving and emerging risks. The ERMC ensures each risk is reviewed by a cross-functional team and provides a robust system of accountability.

Although not exhaustive, the following is a summary of the briefings and reports the Board and its committees receive from management in connection with the Board's risk oversight function.

Corporate Governance
Board Leadership Structure
Chair of the Board
Our Bylaws provide that our directors will designate a Chair of the Board from among its members. The Chair presides at all Board and shareholder meetings. The Chair interacts directly with all members of the Board and assists the Board to fulfill its responsibilities, including those related to risk oversight. As the Principles of Corporate Governance provide, the Board believes it is in the best interests of the Company and its shareholders for the Board to have flexibility to determine the best director to serve as Chair of the Board at the time, based on consideration of all relevant factors.
At least once every year, the Board considers who will best serve as Chair and whether that person should be an independent director given the environment and needs of the Company. The Board has concluded that having Ms. Warden, our Chief Executive Officer, serve as Chair is the most appropriate leadership structure for the Company at this time, and best positions the Company to be innovative, compete successfully, present one face to our customers and advance shareholder interests in today’s environment. The Board believes that Ms. Warden’s years of experience and her deep understanding of the Company’s business, day-to-day operations, growth opportunities, challenges and risk management practices gained through various leadership positions enable her to provide strong and effective leadership to the Board and to ensure that the Board is informed of important issues facing the Company. The Board consists entirely of independent directors, other than Ms. Warden, and continues to exercise a comprehensive, independent oversight function, with fully independent Board committees and a strong Lead Independent Director with clearly articulated responsibilities. The Board will continue to review and discuss the leadership structure of the Board and determine the leadership structure, including the Chair, that best serves the needs of the Company and its shareholders.
Lead Independent Director
If the Chair is not independent, the independent directors will designate annually from among them a Lead Independent Director. Following our 2024 Annual Meeting, the independent directors designated Ms. Kleiner as Lead Independent Director.
Our Principles of Corporate Governance explicitly prescribe a strong role for our Lead Independent Director, describing in detail significant responsibilities with respect to the operation and functioning of the Board and reflecting our commitment to robust corporate governance. The specific duties and responsibilities of the Lead Independent Director include the following:
serve as the principal advisor to the Chair, including in connection with crisis management;
authority to call, establish the agenda and review all the materials for, and chair all meetings of the Independent Directors, including executive sessions regularly scheduled at each full Board meeting, and special sessions of Independent Directors called in case of an emergency or matter requiring their separate consideration or decision;
chair all other meetings of the Board at which the Chair is not present;
regularly meet and consult with the Chair to provide independent oversight, as well as guidance and requests from Independent Directors; review agendas for upcoming Board and committee meetings, and discuss materials to be provided to Directors; review the results of recent Board meetings and agree to next steps; advise the Chair on decisions made by the Independent Directors in executive session and ensure implementation; and consult with the Chair more broadly to help ensure the Board’s effective exercise of governance, risk and oversight responsibilities;
consult with the Chair on the topics to be considered during Board and committee meetings and approve the schedule of Board and committee meetings to ensure there is significant opportunity for the Board to consider properly all necessary agenda items;
serve as a liaison between the Chair and the Independent Directors;
meet with shareholders and other stakeholders as appropriate;
meet with senior management outside of Board meetings periodically and as requested;
interview, along with the Chair and the Chair of the Nominating and Corporate Governance Committee, Board candidates and make recommendations to the Nominating and Corporate Governance Committee and the Board, helping to prioritize the specific skill sets, diverse perspectives, experience and values that candidates for consideration should possess;
coordinate with the Chair on the structure of committee membership and leadership;
support the Chair to help facilitate succession planning and management development;
lead the annual evaluation of the Chair and CEO;

Corporate Governance
evaluate, along with the Chair, Nominating and Corporate Governance Committee (or Chair of the Board, as appropriate) whether a Board member's service on another company's board would interfere with such Board member's duties and responsibilities as a member of the Board;
oversee, along with the Chair, Nominating and Corporate Governance Committee, the evaluation of the performance of the Board and meet with independent directors to discuss results of director peer evaluations; and
perform such other duties as may be assigned by the Board.
Our Lead Independent Director plays a critical role in reviewing director feedback received through the annual director evaluation process and providing feedback to each director on their individual performance.

Corporate Governance
Board Meetings and Executive Sessions
The Board meets no fewer than nine times each year (including via telephonic meetings). Special meetings of the Board may be called from time to time as appropriate. On an annual basis, the Board holds an extended meeting to review our long-term strategy.
The Board often holds its meetings at Company locations other than our corporate headquarters to provide the directors with a first-hand view of different elements of our business and an opportunity to interact with local management and employees at various levels.
The Board meets in executive session (with the directors only and then with the independent directors only) following each in-person Board meeting and on other occasions as needed. The Lead Independent Director presides over the executive sessions of the independent directors. The Audit and Risk Committee meets in executive session at least four times each year, and regularly requests separate executive sessions with representatives of our independent auditor and our senior management, including our Chief Financial Officer, General Counsel and our Vice President, Internal Audit. The Compensation and Human Capital Committee also meets in executive session from time to time and regularly receives a report from the Compensation and Human Capital Committee’s independent compensation consultant. The Nominating and Corporate Governance and Policy Committees also meet in executive session as they deem necessary.
Meeting Attendance
In 2024, the Board held nine meetings. Each director serving in 2024 attended 75% or more of the meetings of the Board and the committees on which he or she served during 2024, with the average attendance for all Board and committee meetings being over 97%. Board members are expected to attend each annual meeting, except where the failure to attend is due to unavoidable circumstances. All of our directors attended our 2024 Annual Meeting.
Director Orientation and Continuing Education
Our comprehensive director orientation, continuing education initiatives and site visits help strengthen our Board's oversight function by ensuring that each of our directors have a deep understanding of our Company, our shareholders and the trends that impact our business.
NEW DIRECTOR
ORIENTATION
All new directors to the Board receive in-person orientation and training that is individually tailored, taking into account the director’s experience, background, education and committee assignments. The orientation program is led by members of senior management and covers a review of our strategy and operating plans, financial statements, corporate governance and key policies and practices, as well as the roles and responsibilities of our directors.
All directors receive regular in-person training regarding our Company policies and procedures, including the Standards of Business Conduct, and broad exposure to our operations and teams. Members of senior management review with the Board the operating plan for each of our business sectors and the Company as a whole.
CONTINUING
DIRECTOR EDUCATION
AND SITE VISITS
Directors attend outside director and other continuing education programs to assist them in staying current on developments in corporate governance, our industry, the global environment and issues critical to the operation of public company boards.
The Board also conducts periodic site visits to our facilities as part of its regularly scheduled Board meetings, and during “Sector Days,” when our directors visit our business operations to meet with local employees and management. These visits allow directors to interact with a broader group of our executives and employees and gain firsthand insights into our operations.

Corporate Governance
Director Independence
The Board and the Nominating and Corporate Governance Committee annually review the relevant relationships or arrangements between the Company and our directors or parties related to the directors in determining whether such directors are independent. No director is considered independent unless the Board has determined that the director meets the independence requirements under applicable New York Stock Exchange (NYSE) and SEC rules and under our categorical independence standards, which are described in our Principles of Corporate Governance. For a director to be considered independent, the Board must determine that a director has no material relationship with the Company other than as a director.
Our Principles of Corporate Governance provide that a director may be found not to qualify as an independent director if the director:
has within the prior three years been a director, executive officer or trustee of a charitable organization that received annual contributions from the Company exceeding the greater of $1 million or 2% of the charitable organization’s annual gross revenues, where the gifts were not normal matching charitable gifts, did not go through normal corporate charitable donation approval processes or were made “on behalf of” a director;
has, or has an immediate family member who has, within the prior three years been employed by, a partner in or otherwise affiliated with any law firm or investment bank in which the director’s or the immediate family member’s compensation was contingent on the services performed for the Company or in which the director or the immediate family member personally performed services for the Company and the annual fees paid by the Company during the preceding fiscal year exceeded the greater of $1 million or 2% of the gross annual revenues of such firm; or
has, or has an immediate family member who has, within the prior three years owned, either directly or indirectly as a partner, shareholder or officer of another company, more than 5% of the equity of an organization that has a material business relationship with (including as a significant purchaser or supplier of goods or services), or more than 5% ownership in, the Company.
Independence Determination
In connection with their annual independence review, the Board and Nominating and Corporate Governance Committee considered certain relationships with organizations to which we have made payments or from which we have received payments in the usual course of our business in 2024. The Board of Directors considered that Mr. Abney, Ms. Brown, Ms. Fudge, Mr. Krishna, Mr. Robinson, Ms. Ross, Adm. Roughead, Mr. Schoewe, Mr. Turley, Gen. Welsh and Ms. Winston served as members of the board of directors or trustees and/or employees or executive officers of companies with which we do business or have made payments in the ordinary course.
The Board of Directors considered that Ms. Ross, Adm. Roughead and Mr. Turley served as members of the boards of organizations to which the Company made contributions during 2024 in the usual course of our charitable contributions program, or in connection with our matching gifts program (which limits the contributions to $10,000 per year per director). The amounts paid were below the applicable thresholds under NYSE rules and our Principles of Corporate Governance.
Following its review and the recommendation of the Nominating and Corporate Governance Committee, the Board affirmatively determined that all of the directors, except Ms. Warden, are independent. The independent directors constitute approximately 92% of the members of our Board.

Corporate Governance
Our Culture
Our strong culture — founded on our values; reflecting our commitment to ethics and integrity; enabling our employees to feel respected, included, and that they belong so they can perform at their best; and focused on enduring performance, innovation, agility and accountability — enables our success and long-term sustainable growth. Culture is critical to who we are and how we do business. Our values guide our Company and provide the foundation for our culture. Our culture is critical to our ability to do business, to attract and retain talent, to perform, to earn trust, to serve our customers and to deliver long-term value for our shareholders. Our entire Company shares the responsibility to maintain and enhance it.
We are proud of our long-standing service to our communities and the progress we have driven across the various aspects of sustainability. Corporate responsibility and sustainability help us drive long-term value creation for our shareholders, customers, employees and suppliers, and the communities we serve.
Management establishes and reinforces the Company’s culture, and our Board is actively engaged in providing oversight. The Board is committed to sustaining and enhancing the Company’s strong culture. For example:
The Company conducts an annual employee experience survey, which gives our employees the opportunity to provide feedback on our Company culture and the environment that enables their success. This survey is managed by a third-party vendor to encourage candor and solicit feedback on many aspects of the employee experience, including ethical climate, career development, enablement, team culture, manager effectiveness, belonging and well-being. The results of this survey are reported to and discussed with the full Board annually.
The Board meets regularly with employees at all levels to reaffirm the health of our culture. The Board meets with employees during site visits that are a critical part of Board meetings, and also during “Sector Days,” when our directors visit the operations across our four business sectors.
Members of our Board often share their time by generously participating as speakers in Company leadership programs.
The Board’s committees oversee elements of the Company’s culture associated with their respective area of responsibility. For example:
The Audit and Risk Committee reviews and discusses the Company’s global compliance programs and policies with our General Counsel and CECO, including the Company’s Standards of Business Conduct and related business conduct policies, and the tone set by leaders throughout the organization, and they meet periodically with our CECO to receive a report on matters that are communicated through the Company's OpenLine reporting system.
The Compensation and Human Capital Committee reviews with the CHRO the Company’s human capital management, oversees policies and practices with respect to employee experience and engagement and reviews a risk assessment of the Company’s compensation programs.
The Nominating and Corporate Governance Committee provides the Board oversight of the Company’s corporate culture and governance-related risks.
The Policy Committee reviews and provides oversight of the Company's policies and programs with respect to sustainability and environmental matters, human rights, health and safety, and corporate social responsibility, including support of charitable organizations.

Corporate Governance
Board Memberships and External Relationships
While the Company recognizes the importance of having directors with significant experience in other businesses and activities, directors are required to ensure that other commitments, including, for example, other board memberships, employment, partnerships and consulting arrangements, do not interfere with their duties and responsibilities as members of the Board. Under our Principles of Corporate Governance, directors are required to provide notice to the General Counsel prior to accepting an invitation to serve on the board of any other organization or agreeing to other new commitments that could interfere with their duties and responsibilities as a member of our Board. The General Counsel then advises the Chair of the Nominating and Corporate Governance Committee (or the Chair of the Board, if notice is from the Chair of the Nominating and Corporate Governance Committee) and the Lead Independent Director. Our policies provide that a director should not accept the new commitment until advised by the Chair of the Nominating and Corporate Governance Committee (or Chair of the Board, as appropriate) that such engagement will not unacceptably create conflicts of interest or regulatory issues, conflict with Company policies or otherwise interfere with the director’s duties and responsibilities as a member of our Board. Directors are also required to promptly inform the General Counsel if an actual or potential conflict of interest arises, or they are concerned that a conflict may arise or circumstances exist that could otherwise interfere with their duties and responsibilities as a director. Directors are required to seek to avoid even an appearance of an improper conflict of interest.
Additionally, when a director’s principal occupation or business association changes substantially during his or her tenure as a director, our policies provide that the Board expects the director to tender his or her resignation for consideration by the Nominating and Corporate Governance Committee, which subsequently will recommend to the Board what action to take.
Director Overboarding
The Board regularly reviews the ability of our directors to devote the necessary time and resources to their service on the Board. At least annually, the Board considers the outside time commitments of all directors, including their service on other public company boards, as well as committee assignments and any leadership roles on those boards. Additionally, as part of the Board's annual self-assessment process, each non-employee director completes an individual director evaluation for each of the other non-employee directors. This evaluation includes an assessment as to whether each director commits sufficient time to the Board.
Our Board seeks to ensure that each director has the time and ability to engage fully to fulfill their responsibilities to our Company, provide effective oversight and advance the long-term interests of our shareholders.
In furtherance of this goal, our policies provide that independent directors may not serve on more than three other boards of publicly traded companies in addition to our Board, and a director who is a full-time employee of our Company may not serve on the board of more than one other public company, absent special approval.
Further, as discussed above, the Board and the Nominating and Corporate Governance Committee also have a robust process for assessing whether a director’s service on another board could create conflicts or otherwise potentially interfere with their responsibilities as a Northrop Grumman director, before the director accepts service on such other board.
In 2024, the Board conducted its regular review of directors’ other commitments and determined each director was in compliance with applicable policies.

Corporate Governance
Annual Self-Assessment Process
Each year, the Board conducts thorough self-assessment processes at each of the full Board level, within each committee, and at the individual director level. These processes are designed to ensure and enhance the effective operation of the Board. These evaluations also assist the Nominating and Corporate Governance Committee with its recommendation for directors to be renominated for election to the Board of Directors.
BOARD
EVALUATION
The self-assessment of the full Board is overseen by the Nominating and Corporate Governance Committee. As part of this assessment, the Lead Independent Director and Chair of the Nominating and Corporate Governance Committee facilitate a broad discussion of Board performance, held in executive session. Among other topics, the Board considers:
the Board’s effectiveness in evaluating and monitoring the Company’s business plan, long-term strategy and risks;
whether strategic and critical issues are being addressed by the Board in a timely manner;
whether the Board’s expectations and concerns are openly communicated to and discussed with the Chief Executive Officer;
whether there is adequate contact between the Board and members of senior management;
whether the directors collectively operate effectively as a Board;
whether the individual directors have the appropriate mix of attributes and skills to fulfill their duties as directors of the Company;
whether there are adequate opportunities to raise questions and comments on issues, both inside and outside of Board meetings;
whether the Board has focused adequately on succession planning; and
whether the Board is adequately responsive to shareholder communication.
Following this review, the Board discusses the results and identifies opportunities for improvement, including any necessary steps to implement such improvements.
COMMITTEE
EVALUATION
Each of the Committees also conducts an annual self-assessment. During an executive session led by the Committee chair, each Committee considers, among other topics: whether the quality of participation and discussion at the Committee meetings is effective in facilitating the Committee’s fulfillment of its obligations under its charter; whether the Committee has sufficient opportunity to engage in strategic discussion; and whether the Committee is covering the right topics in the right amount of detail. Following this discussion, the Committee develops and implements a list of action items, as appropriate.
INDIVIDUAL
DIRECTOR
EVALUATION
Also as part of the annual self-assessment process, each non-employee director completes an individual director evaluation for each of the other non-employee directors. These evaluations address various aspects of how each director contributes to the Board and serves our shareholders. The evaluation results are compiled and provided directly to the Chair, the Lead Independent Director and the Chair of the Nominating and Corporate Governance Committee. These assessments include, among other topics, each non-employee director’s:
understanding of the Company’s overall business and risk profile and its significant financial opportunities and plans;
engagement during meetings and ability to commit sufficient time to the Board;
analysis of benefits and risks of courses of action considered by the Board; and
appropriate respect for the views of other Board members.
The Lead Independent Director or the Chair of the Nominating and Corporate Governance Committee meets with each non-employee director individually to discuss the results of his or her assessment, including comments provided by other non-employee directors, and opportunities for growth.
SELF-ASSESSMENT
FEEDBACK
The Lead Independent Director or the Chair of the Nominating and Corporate Governance Committee reports generally on the overall results of these discussions to the Board in executive session. These evaluations also assist the Nominating and Corporate Governance Committee with its recommendation for directors to be renominated for election to the Board of Directors.

Corporate Governance
Succession Planning
The Board believes that providing for strong and effective continuity of leadership is critical to the success of our Company. The Board commits significant resources to ongoing succession planning, with processes in place for the Board:
to evaluate the Chief Executive Officer annually based on a specific set of performance objectives;
to work with the Chief Executive Officer to support and ensure the development of potential succession candidates for the Chief Executive Officer and other leadership positions;
to discuss with the Chief Executive Officer annually an assessment of persons considered potential successors to various senior management positions; and
robustly to consider, plan for and ensure successful transitions of leadership.
Additionally, the Nominating and Corporate Governance Committee continuously assesses the composition of the Board and its future needs. The Committee regularly reviews the background, experience, engagement, skills, values and other attributes of current and potential future directors, considering the Company’s requirements for an effective Board and identifying potential current and future gaps.
Communications with the Board of Directors
Any interested person may communicate with any of our directors, our Board as a group, our non-employee directors as a group or our Lead Independent Director through the Corporate Secretary by writing to the following address: Office of the Corporate Secretary, Northrop Grumman Corporation, 2980 Fairview Park Drive, Falls Church, Virginia 22042. The Corporate Secretary will forward correspondence to the director or directors to whom it is addressed, except for job inquiries, surveys, business solicitations or advertisements and other inappropriate material. The Corporate Secretary may forward certain correspondence elsewhere within our Company for review and possible response.
The Board has met with, and looks forward to the opportunity to meet with, interested shareholders to address concerns and to receive input.
Interested persons may also report any concerns relating to accounting matters, internal accounting controls or auditing matters to non-management directors (including anonymously) by writing to the Chair of the Audit and Risk Committee, Northrop Grumman Board of Directors c/o Corporate Ethics and Compliance Office, 2980 Fairview Park Drive, Falls Church, Virginia 22042.

Retainer fees are paid in arrears on a quarterly basis at the end of each quarter.
To encourage directors to have a direct and material investment in shares of our common stock, non-employee directors are awarded an annual equity grant of $182,500 in the form of deferred stock units (Automatic Stock Units).
The Compensation and Human Capital Committee, with the assistance of its independent compensation consultant, is responsible for reviewing and recommending for Board approval the compensation of the non-employee directors. At the request of the Compensation and Human Capital Committee, the independent compensation consultant prepares annually a comprehensive benchmarking of our non-employee director compensation program against the compensation programs offered by our Target Industry Peer Group (the same peer group against which executive compensation is compared). Consistent with this benchmarking, the overarching approach for non-employee director compensation is to target approximately the 50th percentile of the Target Industry Peer Group and to align our director compensation with our shareholders’ interests.

Compensation of Directors
Awards to non-employee directors are made pursuant to the Northrop Grumman Corporation Equity Grant Program for Non-Employee Directors (the Director Program). The Director Program was amended and restated effective January 1, 2016 (the Amended Director Program). Non-employee directors received an annual equity grant of Automatic Stock Units on May 17, 2023 which vested on May 17, 2024. The Director Program was again amended and restated effective May 15, 2024, consistent with the shareholder-approved 2024 Long-Term Incentive Stock Plan (the Restated Director Program). Non-employee directors received an annual equity grant of Automatic Stock Units on July 31, 2024 which will vest on May 15, 2025. Under the Amended Director Program and Restated Director Program, directors may elect to have all or any portion of their Automatic Stock Units paid on (A) the earlier of (i) the beginning of a specified calendar year after the vesting date or (ii) their separation from service as a member of the Board, or (B) the vesting date. Directors may elect to defer to a later year all or a portion of their remaining cash retainer or committee retainer fees into a stock unit account as Elective Stock Units or in alternative investment options. Elective Stock Units are awarded on a calendar quarterly basis. Directors may elect to have all or a portion of their Elective Stock Units paid on the earlier of (i) the beginning of a specified calendar year or (ii) their separation from service as a member of the Board. Stock units awarded under the Amended Director Program and Restated Director Program will be paid out in an equivalent number of shares of our common stock. Deferral elections are made prior to the beginning of the year for which the retainer fees will be paid. Directors are credited with dividend equivalents in connection with the accumulated stock units until the shares of common stock related to such stock units are issued.
Non-employee directors are eligible to participate in our Matching Gifts Program for Education. Under this program, the Northrop Grumman Foundation matches director contributions, up to $10,000 per year per director, to eligible educational programs in accordance with the program.
Stock Ownership Requirements
Non-employee directors are required to own common stock of the Company in an amount equal to five times the annual cash retainer, with such ownership to be achieved within five years of the director’s election to the Board. Deferred stock units and Company stock owned outright by the director count towards this requirement.
Anti-Hedging and Pledging Policy
Company policy prohibits our directors, NEOs, other elected and appointed officers, designated employees who are subject to specific preclearance procedures under the Company’s insider trading policy and any other employees who receive performance-based compensation, from engaging in hedging, pledging or other specified transactions. Specifically, this policy prohibits such persons from: engaging in hedging or derivative transactions, such as “cashless” collars, forward contracts, equity swaps or other similar or related transactions; entering into margin transactions involving Company stock; pledging Company securities as collateral for loans or other transactions; trading in puts, calls, options, warrants or other similar derivative instruments involving Company securities; or engaging in short sales of Company securities.
None of the shares of Company common stock held by our directors are pledged or subject to any hedging transaction.

Proposal 2: Advisory Vote on Compensation of Named Executive Officers
Consistent with Section 14A of the Exchange Act, we are providing our shareholders with the opportunity to cast a non-binding, advisory vote on the compensation of our NEOs. This advisory vote, commonly known as “say-on-pay,” gives our shareholders the opportunity to express their views on our 2024 executive compensation programs and policies for our NEOs. The vote does not address any specific item of compensation and is not binding on the Board; however, as an expression of our shareholders’ views, the Compensation and Human Capital Committee seriously considers the vote when making future executive compensation decisions. The Board has adopted a policy of providing for annual advisory votes on the compensation of our NEOs.
We believe our compensation programs reflect responsible, measured practices that effectively incentivize our executives to dedicate themselves fully to value creation for our shareholders, customers and employees. Our pay practices are aligned with our shareholders’ interests and with leading industry practice and are governed by a set of strong policies. Examples include:
Double-trigger provisions for change in control situations, and no excise tax gross-ups for payments upon termination after a change in control;
A recoupment policy applicable to cash and equity incentive compensation payments;
Stock ownership guidelines of 7x base salary for the CEO and 3x base salary for other NEOs, and stock holding requirements of three years from the date paid for 50% of all net after-tax shares received; and
Prohibitions on hedging or pledging of Company stock.
For a more extensive list of our best practices, refer to page 53 of this Proxy Statement. In addition, our Compensation Discussion and Analysis (CD&A) provides a detailed discussion of our performance-based approach to executive compensation. We encourage you to read the CD&A, the rest of this Proxy Statement and our 2024 Form 10-K, which describes our business and 2024 results in more detail.
Recommendation
The compensation of our executives is aligned to performance, is sensitive to shareholder returns, appropriately motivates and retains our executives, and is a competitive advantage in attracting and retaining the high caliber talent necessary to drive our business forward and build sustainable value for our shareholders. Accordingly, the Board recommends that shareholders approve the following resolution:
“RESOLVED, that, as an advisory matter, the shareholders of Northrop Grumman Corporation approve the compensation paid to the Company’s named executive officers as disclosed in this Proxy Statement pursuant to Item 402 of Regulation S-K, including the CD&A, compensation tables and narrative discussion.”
Vote Required
Approval of this proposal requires that the votes cast “for” the proposal exceed the votes cast “against” the proposal. Abstentions and broker non-votes will have no effect on this proposal.

Executive Leadership Changes
In May 2024, the Company announced changes within the Company’s executive leadership team stemming from the retirements of two leaders.
Roshan Roeder, who most recently served as Corporate Vice President and President, Defense Systems, succeeded Mark Caylor as Corporate Vice President and President of Mission Systems effective July 1, 2024. Mr. Caylor retired from the Company on July 26, 2024, after many significant contributions, key roles and more than 20 years with the Company.
In addition, Kenneth Crews was elected Corporate Vice President and Chief Financial Officer, effective October 1, 2024. Mr. Crews joined Northrop Grumman in 2004 and has held several key financial roles in multiple sectors throughout the Company, including as the CFO of the Space Systems sector and Mission Systems sector. Most recently he served as Vice President, Corporate Finance working directly with former Chief Financial Officer, David Keffer, to facilitate a successful transition. Mr. Keffer retired on February 21, 2025, after five years with the Company. During this time, Mr. Keffer played a key role in guiding the Company's financial strategy, increasing shareholder value and strategically positioning the Company for future growth and success. Mr. Keffer remained an employee of the Company and advisor to Ms. Warden and Mr. Crews until his retirement. As a former Chief Financial Officer, Mr. Keffer's inclusion in this Compensation Discussion and Analysis (CD&A) is required by SEC rules.
These transitions demonstrate the Company’s commitment to thoughtful and well-executed succession planning.

Executive Compensation

Compensation Philosophy and Objectives
We provide attractive, flexible and market-based total compensation programs tied to performance and aligned with the interests of our shareholders. Our objective is to recruit and retain the caliber of executives and other key employees capable of achieving top performance and generating value for our shareholders, customers and employees.
Our goal is to lead our industry in sustainable performance and build on our strong, enduring values. For our performance-based plans, we select metrics that drive shareholder value and benchmark our performance against peers, the market and our long-range strategic plan (LRSP). Our executive compensation and benefit programs are guided by the following principles:
pg_49_icon_PayPerf.jpg
Pay for Performance
Our incentive plans are based on peer performance and benchmarks, the market and our LRSP.
Above-target incentive payouts are awarded when we outperform our peers, market and LRSP benchmarks.
pg_49_icon_LeadRecruit.jpg
Leadership Recruitment, Retention and Succession
Compensation is designed to be competitive with our peers and retain top talent.
Programs are structured to attract, motivate and reward NEOs for delivering strong operational and strategic performance over time.
icon_ExecutiveComp_option3.jpg
Sustainable Performance
Our Annual Incentive Plan includes both financial and non-financial metrics to ensure we are building a strong foundation for long-term sustainable performance and shareholder value creation, and we are consistent with our commitment to sustainability.
pg_50_icon_Alignment.jpg
Alignment with Shareholder Interests
Our compensation structure places an appropriate amount of compensation at risk based on annual and long-term results.
At-risk compensation is based on financial and non-financial performance measures and relative Total Shareholder Return (rTSR). Payouts under the rTSR portion of the plan are capped at target if the Company’s TSR is negative over the three-year performance period.
A significant portion of compensation is delivered in equity, the vesting and value of which provides alignment with shareholder returns.
Stock ownership guidelines, holding requirements for vested equity awards and our recoupment policy further align executive and shareholder interests.
pg_50_icon_Benchmark.jpg
Benchmarking
Our compensation programs’ provisions and financial objectives are evaluated on an annual basis and modified in accordance with industry and business conditions (e.g., divestitures, unforeseen impacts, etc.).
Benchmarks are set using a hybrid approach of peer, market and LRSP data.
We seek to outperform our peers (a group of top global defense companies identified as the Performance Peer Group on page 55 ).
We use a Target Industry Peer Group (TIPG) (identified on page 55 ) for broader market executive compensation analyses that includes comparisons to companies that reflect the labor market for executive talent.

Consideration of Say-On-Pay Vote
The Company annually asks shareholders to approve, on an advisory basis, the compensation paid to our NEOs. We regularly engage with our shareholders to address their questions regarding executive compensation and emphasize our philosophy and competitive pay practices. The Compensation and Human Capital Committee annually reviews and discusses the results of the say-on-pay vote. In 2024, our executive compensation programs continued to receive strong support from shareholders with 94% approval at our 2024 Annual Meeting of Shareholders. Based on its review and feedback from shareholder engagement, the Compensation and Human Capital Committee determined that our programs are effective and aligned with shareholder interests, and no substantive changes were required.

Executive Compensation
Use of Competitive Data
Our Compensation and Human Capital Committee uses three separate peer groups to set our performance targets and evaluate performance, measure TSR and benchmark executive compensation practices, respectively. The three peer groups are outlined below.
PERFORMANCE PEER GROUP: SET PERFORMANCE TARGETS AND EVALUATE PERFORMANCE
The Compensation and Human Capital Committee uses the Performance Peer Group and LRSP (our five-year strategic operating and financial plan) data for the purpose of setting performance targets and evaluating performance of our AIP and LTIP. The Performance Peer Group encompasses the largest global defense companies by government revenues within the aerospace and defense market space. In 2024, the Compensation and Human Capital Committee used the peer group data from The Boeing Company, General Dynamics Corporation, L3Harris Technologies, Inc., Lockheed Martin Corporation and RTX Corporation for the purpose of setting performance targets.
TSR PEER GROUP: 2022-2024 LONG-TERM INCENTIVE AWARDS
Earned awards from the 2022-2024 performance cycle were contingent on our ranking compared to the S&P Industrials and the following TSR peer group:
2022 TSR PEER GROUP
BAE Systems L3Harris Technologies, Inc.
RTX Corporation
The Boeing Company Leidos Holdings, Inc. Thales Group
General Dynamics Corporation Leonardo
Huntington Ingalls Industries, Inc.
Lockheed Martin Corporation

TARGET INDUSTRY PEER GROUP (TIPG): BENCHMARK EXECUTIVE COMPENSATION PRACTICES
The Compensation and Human Capital Committee benchmarks our executive compensation levels and practices against the TIPG of 22 companies, including a subset containing six direct peers. Prior to the beginning of the year, the Compensation and Human Capital Committee sets the TIPG based on recommendations from the Independent Compensation Consultant. The TIPG is used to benchmark compensation for the following year. To identify peer companies for compensation benchmarking purposes, the Independent Compensation Consultant employs an objective criteria-based methodology where:
the peer company was identified as part of a subset of direct peers with strong alignment to the aerospace and defense industry;
the peer company was identified as a Global Industry Classification Standard company, with a prioritization of technology, manufacturing and engineering companies;
revenues, total employees and market capitalization of the peer company were broadly similar to those of the Company; and
the peer company participated in an annual third party compensation study.

The Compensation and Human Capital Committee reviews the TIPG annually with the Independent Compensation Consultant. The companies that comprise the 2023 TIPG used for 2024 compensation decisions are listed in the following table:

Number of Employees

It is the Company’s pay philosophy to provide the CEO a compensation package that includes competitive elements of base salary and target variable pay relative to the TIPG and the direct six peers noted in the table above.
Another element of the Company’s pay philosophy is to tie a significant portion of the CEO’s pay to performance. As a result, the CEO’s actual compensation may differ from the market median based on the Company’s actual performance.
In determining the base salary and target variable pay elements for the other NEOs, the Compensation and Human Capital Committee establishes the TIPG median as the benchmark. The Compensation and Human Capital Committee also considers several factors in determining their compensation, including executive compensation levels and practices of the TIPG, NEO individual experience, growth in job as demonstrated through sustained performance, leadership impact, retention and pay relative to the CEO. Actual annual incentive awards and long-term incentive award opportunities reflect these factors, as well as Company performance.

Key Components of Our Executive Compensation Programs
Base Salary
The Compensation and Human Capital Committee believes that competitive base salaries are necessary to attract and retain our NEOs. Base salaries are evaluated each year and determined by level of responsibility, competitive market pay assessment and individual performance. The table below reflects each NEO currently serving and their annual base salary as an elected officer, effective as of December 31 for the respective year, and year-over-year change if an NEO for two consecutive years.

Annual Incentive Compensation
Our NEOs are eligible to receive annual cash bonuses under our 2006 Annual Incentive Plan and Incentive Compensation Plan, as amended and restated effective January 1, 2024 (AIP). We use a balance of financial and non-financial performance metrics aligned with our long-term strategy.
TARGET AWARD LEVELS FOR 2024 AIP
The Compensation and Human Capital Committee approves the annual incentive compensation target payout percentage for each NEO, other than the CEO. For the CEO, such percentage is approved by the independent directors of the Board.
The target incentive award (target bonus) represents a percentage of each NEO’s base salary. Following the completion of the fiscal year, the target bonus is used by the Compensation and Human Capital Committee, together with its assessment of Company and individual performance against established performance criteria, to determine the final bonus award amount. The table below reflects each NEO currently serving and their annual target bonus as an elected officer, effective as of December 31, 2024.
Name Target Bonus (% of Base Salary)
Kathy J. Warden 195 %
Kenneth B. Crews 100 %
Robert J. Fleming 100 %
Thomas H. Jones 100 %
Roshan S. Roeder 100 %
Final bonus awards for each NEO were determined by multiplying the Northrop Grumman Company Performance Factor (CPF) by the target bonus. The CPF can range from 0% to 200%.

(1) The CPF, which is capped at 200%, is comprised of two components, the Company Metrics Score (financial and non-financial), which can range from 0% to 200%, and a Strategic and Operational Assessment, which can range from 80% to 120%. The Strategic and Operational Assessment allows for broader application of business results not formally reflected in the core financial or non-financial metrics.
Annual performance evaluations are conducted by the Compensation and Human Capital Committee for the CEO, and by the CEO for each other NEO with review by the Compensation and Human Capital Committee. The Compensation and Human Capital Committee considers this performance information as well as the comparison to market data.
2024 AIP METRICS
For the 2024 AIP, and as in prior years, we used a mix of financial and non-financial metrics to measure our performance. Our AIP metrics reflect our commitment to investing for and achieving long-term profitable growth, maintaining alignment with shareholders’ interests, and incentivizing top performance against our industry peers.
Financial Metrics (90% Weight)
For 2024, the Compensation and Human Capital Committee determined the financial metrics would be Adjusted Cash Flow from Operations*and Segment Operating Income* Growth, each weighted at 35% and Pension-Adjusted OM Rate* weighted at 20%. The financial metrics are defined as follows:
Financial Metrics
Weighting
Rationale
Calculation
ADJUSTED CASH FLOW FROM OPERATIONS*
35%
Emphasizes the importance of generating cash for strategy execution. The metric incentivizes management to make capital investment decisions that support long-term profitable growth.
Net cash provided by operating activities, including adjustments as approved by the Compensation and Human Capital Committee.
SEGMENT OPERATING
INCOME* GROWTH
35% Incentivizes management to focus on profitable growth and enables management to evaluate the financial performance and operational trends of our sectors.
The combined operating income of our four segments, less the operating income associated with intersegment sales.
PENSION-ADJUSTED OM RATE*
20% Establishes high program performance expectations for the Company and incentivizes sound core operational business strategies. Operating income before FAS/CAS operating adjustment and excluding unallocated state tax impacts reflected within unallocated corporate income (expense) and other approved adjustments, divided by sales.
* This metric is a non-GAAP financial measure. For more information, see “Appendix A - Use of Non-GAAP Financial Measures.”

Non-Financial Metrics (10% Weight)

Payout Levels
Our AIP provides for payout levels from 0% to 200% of target. The minimum, target and maximum performance levels are derived based on an analysis of the historical and forecasted performance of our Performance Peer Group, and LRSP data for the Adjusted Cash Flow from Operations*, Segment Operating Income* Growth, and Pension-Adjusted OM Rate* metrics. The non-financial metrics’ performance levels are determined by specific goals approved by the Compensation and Human Capital Committee. Specific values are identified for each metric at selected points in the range between minimum and maximum and other values are determined by linear interpolation between these points. No payout is made if performance is below the minimum. Above-target payouts can be earned only if the Company’s performance exceeds the performance threshold noted in the table on the following page. The maximum payout of 200% is achieved if the Company’s performance is above the approximate top quartile performance target. This structure aligns above-target payouts with superior performance and provides reduced awards for below-target performance.

2024 AIP PERFORMANCE RESULTS
In determining the CPF, both financial and non-financial performance against goals are assessed. The 2024 Company Metrics Score based on the financial and non-financial metrics, was determined to be 148%. The Strategic and Operational Assessment was determined to be 100%, resulting in an overall CPF of 148%.
As approved by the Compensation and Human Capital Committee, 2024 Company performance calculations were adjusted, as applicable, to exclude the impact of net operating FAS/CAS, deferred state tax expense (benefit), CAS pension recoveries, and other adjustments to account for business conditions and certain costs unanticipated at the time the goals were established. All adjustments were made by the Compensation and Human Capital Committee using its discretion, as provided in our plan, to measure annual incentive performance while maintaining flexibility to provide equitable adjustments that address the impact of material non-operational and unforeseen events. Details are outlined in Appendix A - Use of Non-GAAP Financial Measures.

Executive Compensation
Compensation and Human Capital Committee Discretion
The Compensation and Human Capital Committee approves bonus amounts for all NEOs except the CEO, whose annual bonus is recommended by the Compensation and Human Capital Committee to the independent directors of the Board for approval. The Compensation and Human Capital Committee has discretion to make adjustments to the annual bonus payouts for NEOs, other than the CEO, if it determines such adjustment is warranted due to unforeseen or unusual events. In 2024, the Compensation and Human Capital Committee made no additional adjustments to the recommended CPF or individual AIP participants’ awards.
2024 NEO AIP PAYOUTS
In consideration of both the financial and non-financial performance, the 2024 Company Performance Factor (CPF) was determined to be 148%.
In February 2025, the Compensation and Human Capital Committee recommended, and the independent directors of the Board approved, a 2024 annual incentive award of $5,194,800 for our CEO, Ms. Warden. Based on the CPF and individual performance, Ms. Warden recommended, and the Compensation and Human Capital Committee approved, the other NEOs’ annual incentive awards.

(2) Mr. Crews was elected Corporate Vice President and Chief Financial Officer effective October 1, 2024. His target and actual payout under the AIP are prorated to reflect time served as an elected and appointed officer at the Corporate Office and as an appointed officer at the Space Systems Sector. The AIP metrics are enterprise-wide and measured at both the Company and Sector level.
Long-Term Incentive Compensation
In 2024, the Compensation and Human Capital Committee granted awards in the form of Restricted Performance Stock Rights (RPSRs) and Restricted Stock Rights (RSRs). The awards were comprised of 70% RPSRs and 30% RSRs. The Compensation and Human Capital Committee determined this long-term incentive mix would appropriately motivate and reward the NEOs to achieve our long-term objectives and further reinforce the link between their interests and the interests of our shareholders.
pg64_piechart_RPSR.jpg
Restricted Performance Stock Rights (RPSRs)
The RPSRs ensure sustainability and achievement of business goals over time. The RPSRs will vest and be distributed following the completion of the three-year performance period (commencing January 1, 2024, and ending December 31, 2026) if goals are met.
pg64_piechart_RSR.jpg
Restricted Stock Rights (RSRs)
The RSRs provide retentive value and generally vest 100% after three years.
Earned RPSRs and RSRs may be paid in shares, cash or a combination of shares and cash at the Compensation and Human Capital Committee’s discretion. An executive generally must remain employed through the vesting period to earn an award. Vesting for termination due to death, disability, retirement or change in control is discussed in the “Termination Payments and Benefits” section on page 79 . Dividend equivalents accrue on both RPSR and RSR awards earned and will be paid upon distribution of the RPSRs and RSRs. Following the distribution, 50% of all net after-tax shares received are subject to a three-year mandatory holding requirement.

RESTRICTED PERFORMANCE STOCK RIGHTS
The Compensation and Human Capital Committee evaluates RPSR performance requirements each year to ensure they are aligned with our business objectives. For the 2024 RPSR grant, the Compensation and Human Capital Committee determined that for the NEOs, performance metrics would be Adjusted Cumulative FCF*, Return on Invested Capital* (ROIC) and Relative Total Shareholder Return, each equally weighted at 1/3. The current metrics and weightings reflect the Company’s continued emphasis on operational performance directly impacted by management decisions and behaviors, while maintaining strong alignment with shareholder interests. Based on the performance against these metrics, shares earned for 2024 RPSR grants can vary from 0% to 200% of the rights awarded.
2024 RPSR Performance Measures
RPSR Metrics Weighting Rationale Calculation
ADJUSTED CUMULATIVE FCF* 1/3 Focuses on cash generation to create shareholder value after investing in the business through capital expenditures.
Adjusted Cumulative FCF* focuses on cash generation after capital investments and is calculated as the aggregate Adjusted Free Cash Flow Before After-Tax Total Pension Funding*, adjusted to exclude total CAS pension recovery and other approved adjustments over a three year period.
RETURN ON INVESTED CAPITAL* 1/3 Focuses on effective and profitable deployment of Invested Capital* resources Return on Invested Capital* is calculated as the three-year average of Pension-Adjusted Net Operating Profit After-Tax* (Pension-Adjusted NOPAT*) divided by the three-year average of Invested Capital*.
RELATIVE TOTAL SHAREHOLDER RETURN 1/3 Aligns the interests of executives with shareholders. Relative TSR (rTSR) is measured by comparing cumulative stock price appreciation with reinvestment of dividends over the three-year period to the TSR Peer Group (50% of rTSR portion of award) and to the S&P Industrials (50% of rTSR portion of award), which comprises companies within the S&P 500 classified as Industrials, reflecting the range of similar investment alternatives available to our shareholders. To smooth volatility in the market, the TSR calculation is based on the average of the three-year returns for each of the 30 calendar days, starting from the grant date, to the last 30 days of the performance period. The maximum rTSR payout is capped at 100% of target shares if the absolute TSR is negative, even if the rTSR would have resulted in a higher score.
* This metric is a non-GAAP financial measure. For more information, see “Appendix A - Use of Non-GAAP Financial Measures.”

Recently Completed RPSR Performance Period (2022-2024)
In February 2022, when granting RPSRs to NEOs who were elected officers at the time of the grant, the Compensation and Human Capital Committee selected Adjusted Cumulative FCF*, Return on Invested Capital* and rTSR, equally weighted at 1/3, as the performance metrics for the awards and established the performance criteria for the awards as set forth in the table below. Based on the performance against these metrics, shares earned for 2022 RPSR grants can vary from 0% to 200% of the rights awarded.

* This metric is a non-GAAP financial measure. For more information, see “Appendix A - Use of Non-GAAP Financial Measures.”
** As approved by the Compensation and Human Capital Committee, Adjusted Cumulative FCF* and Return on Invested Capital* metrics for the 2022 RPSRs were adjusted, as applicable, to neutralize the impact of business conditions and certain costs unforeseen at the time of grant setting. Adjustments include the removal of CAS pension recovery, the IT services divestiture, impacts related to international trade restrictions, assumptions regarding tax legislation related to research credits, plan-based differences in free cash flow related to unanticipated costs on the B-21 program, the impact of a charge associated with the low-rate initial production phase of the B-21 program, the gain on sale of a minority investment in an international business and the loss on divestiture of a small international subsidiary. All adjustments were made by the Committee using its discretion, as provided in our plan, to measure 2022-2024 performance while maintaining flexibility to provide equitable adjustments that address the impact of material non-operational and unforeseen events. Details are outlined in Appendix A - Use of Non-GAAP Financial Measures.
In February 2025, the Compensation and Human Capital Committee reviewed performance for the January 1, 2022 to December 31, 2024 RPSR performance period. The combined weighted score for the metrics generated an overall performance score of 107%.
In February 2025, the NEOs received payouts in stock with respect to the outstanding RPSR awards that were granted in February 2022 for the three-year performance period ending December 31, 2024 (as described further in footnote three of the Outstanding Equity Awards Table on page 73 ).

Executive Compensation
Other NEO Benefits
This section describes other benefits the NEOs receive. These benefits are not performance related and are designed to provide a competitive package for purposes of attracting and retaining the executive talent needed to achieve our business objectives. These benefits include retirement benefits, certain perquisites and severance arrangements.
Retirement Benefits
We maintain tax-qualified retirement plans (both defined benefit pension plans and defined contribution savings plans) that cover most of our workforce, including the NEOs. We also maintain nonqualified retirement plans that are available to our NEOs, which are designed to restore benefits that were limited under the tax-qualified plans or to provide supplemental benefits. Compensation, age and years of service factor into the amount of benefits provided under the plans. Thus, the plans are structured to reward and retain employees of long service and recognize higher performance levels as evidenced by increases in annual pay. The nonqualified supplemental defined benefit plans in which our NEOs participate were frozen as to pay and service as of December 31, 2014.
The Compensation and Human Capital Committee assesses aggregate benefits available to the NEOs and has previously imposed an overall cap, generally limited to no more than 60% of final average pay on pension benefits for the NEOs. Additional information about these retirement plans and the NEO benefits under these plans can be found in the Pension Benefits Table and Nonqualified Deferred Compensation Table, on pages 75 and 78 , respectively.
Perquisites
Our NEOs are eligible for certain limited executive perquisites that include financial planning and income tax preparation, physical exams and personal liability insurance. The Compensation and Human Capital Committee believes these perquisites are common within the competitive market for total compensation packages for executives and are useful in attracting, retaining and motivating talented executives. Perquisites provided to the NEOs in 2024 are detailed in the Summary Compensation Table on page 70 .
Security Arrangements
Given the nature of our business, we maintain a study-based security program. Executive protection, including residential and/or travel, is based on a risk assessment and may change based on the individual’s profile. These security requirements are continuously assessed for each member and provided to the Board for informational purposes generally every three years. In selecting the level and form of protection, we and the Board consider security risks faced by those in our industry in general and security risks specific to our Company and its individuals. Based on security threat information obtained and an ongoing dialogue with law enforcement and security specialists, the Board has required that Ms. Warden and other NEOs receive varying levels of residential and travel protection.
Since we require this protection under a study-based security program and it is not designed to provide a personal benefit (other than the intended security), we do not view these security arrangements as compensation to the individuals. We report these security arrangements as perquisites as required under applicable SEC rules. In addition, we report them as taxable compensation to the individuals if they are not excludable from income as working condition fringe benefits under Section 132 of the Internal Revenue Code.
The Board has determined that the CEO should avoid traveling by commercial aircraft for purposes of security, rapid availability and communications connectivity during travel, and should use Company-provided aircraft for all air travel. If, as a result, the CEO uses Company-provided aircraft for personal travel, the costs of such travel are imputed as income and are subject to the appropriate tax reporting according to Internal Revenue Code regulations.
We regularly review the nature of the security threat and associated vulnerabilities with law enforcement and security specialists and will continue to adapt our security program as appropriate.
Severance Benefits
We maintain the Severance Plan for Elected and Appointed Officers of Northrop Grumman Corporation (Severance Plan), which is available to Ms. Warden and other NEOs who qualify and are approved to receive such benefits. The purpose of the Severance Plan is to help bridge the gap in an executive’s income and health coverage during a period of unemployment following a qualified termination, and to ensure certain benefits for the Company.
We do not maintain any change in control (CIC) severance plans. In addition, we do not provide excise tax gross-ups for any payments received upon termination after a change in control.
2025 Proxy Statement

Executive Compensation
Upon a “qualifying termination” (defined below) the Company may provide severance benefits to eligible NEOs under the Severance Plan. Provided the NEO signs a release and agrees to certain restrictions, he or she may receive: (i) a lump sum severance benefit equal to 1.5x annual base salary and target bonus, (ii) a prorated performance bonus for the year of termination, (iii) continued medical and dental coverage for the 18-month severance period, (iv) income tax preparation/financial planning fees for the year of termination and the following year and (v) outplacement expenses up to 15% of salary, all subject to management approval. The cost of providing continued medical and dental coverage is based upon current premium costs. The cost of providing income tax preparation and financial planning is capped for the year of termination and for the year following termination. The annual cap for the CEO is $30,000 and for the rest of the NEOs is $18,500.
A “qualifying termination” includes one of the following:
involuntary termination, other than for cause or mandatory retirement; or
election to terminate in lieu of accepting a downgrade to a non-officer position (i.e., good reason).
Change in Control Benefits
We do not maintain separate CIC programs or agreements. The only CIC benefits available to the NEOs are those described in the terms and conditions of the grants under the 2011 Long-Term Incentive Stock Plan (2011 Plan) and the 2024 Long-Term Incentive Stock Plan (2024 Plan).

Policies and Procedures
Stock Ownership Guidelines
We maintain stock ownership guidelines for our NEOs to further promote alignment of management and shareholder interests. These guidelines require that NEOs own Company stock with a value denominated as a multiple of their annual salaries, which can be accumulated over a five-year period from the date of hire or promotion into an elected officer position.
The guidelines are as follows:
Position Stock Value as a Multiple of Base Salary
Chair and Chief Executive Officer
pg68_StockOwnershipCEO.jpg
Other NEOs
pg68_StockOwnershipNEOs.jpg
Shares that satisfy the stock ownership guidelines include:
Company stock owned outright;
unvested RSRs; and
the value of shares held in the Northrop Grumman Savings Plan or Northrop Grumman Financial Security and Savings Program.
Unvested RPSRs are not included in calculating ownership until they are converted to actual shares owned. Unexercised stock options are excluded.
The Compensation and Human Capital Committee reviews compliance with our stock ownership guidelines on an annual basis. As of December 31, 2024, all NEOs were in compliance with the ownership guidelines or on track to meet the requirement by the end of the five-year period referenced above. The Compensation and Human Capital Committee continues to monitor compliance and will conduct a full review again in 2025.
Stock Holding Requirements
We have holding period requirements for payouts from long-term incentive grants, further emphasizing the importance of sustainable performance and appropriate risk-management behaviors. Under this policy, NEOs who received grants as an elected officer are required to hold, for a period of three years, 50% of their net after-tax shares received from RPSR and RSR distributions. These restrictions generally continue following termination and retirement; however, shares acquired from RPSR distributions more than one year after separation from the Company are not subject to the holding requirement.

Insider Trading and Anti-Hedging and Anti-Pledging Policy
The Company's insider trading policy governs the purchase and sale of the Company's securities by directors, officers and other employees subject to the policy and is reasonably designed to promote compliance with insider trading laws, rules and regulations and the listing standards of the NYSE. Company policy prohibits our NEOs and other elected officers from hedging or entering into margin transactions involving Company stock, and pledging Company securities as collateral for loans or other transactions. Additional information about our policy can be found in “Compensation of Directors - Stock Ownership Requirements and Anti-Hedging and Pledging Policy” on page 44 . Additionally, the Company's insider trading policy is filed as Exhibit 19 to our 2024 Form 10-K.

Recoupment Policy
The Company’s recoupment policy generally provides that:
if the Company is required to restate its financial results, the Company will attempt to recover reasonably promptly from each executive officer the amount of any erroneously awarded compensation that was received by such officer;
the Board has discretion to recoup performance-based annual, or performance-based and time-based long-term cash or equity, incentive payments (collectively, "incentive compensation") paid to an elected officer in the event of a restatement or if an elected officer engages in illegal conduct that causes significant financial or reputational harm to the Company;
the Board has discretion to recoup incentive compensation paid to the elected officer in the event the elected officer fails to report misconduct of another, or is grossly negligent in fulfilling his or her supervisory responsibilities to prevent such misconduct; and
the CEO has discretion to recoup under similar circumstances incentive compensation provided to non-elected officers or other employees.
The Company’s recoupment policy includes a three-year look back for recovery of the erroneously awarded compensation or other incentive compensation. It also provides for certain disclosure in the event of recoupment, consistent with SEC and other legal requirements. The Company's Recoupment Policy is filed as Exhibit 97 to our 2024 Form 10-K.
Risk Management
The Compensation and Human Capital Committee annually reviews our compensation programs and together with the Independent Compensation Consultant assesses potential compensation-related risks to the Company. Based on this assessment for 2024, the Compensation and Human Capital Committee determined that the risk profile is appropriate and substantial risk management features are incorporated into our compensation programs. This determination reflects the following conclusions from the detailed risk assessment:
there is appropriate balance to mitigate compensation-related risk in the executive compensation programs’ designs between fixed and variable pay, cash and stock components, annual and long-term measures, financial and non-financial measures and formulaic and discretionary decisions;
there are appropriate policies in place to mitigate compensation-related risk, including the Compensation and Human Capital Committee’s and its advisor’s independence, transparent disclosure, officer stock ownership guidelines and holding period requirements, and hedging and recoupment policies; and
there are no incentive or commission arrangements below the executive level that potentially encourage excessive risk-taking behavior.
Tax Deductibility of Pay
Section 162(m) of the Internal Revenue Code generally limits the annual tax deduction to $1 million per person for compensation paid to the Company’s ”covered employees,” defined to include the CEO, CFO, and the next three highest-paid NEOs excluding the CEO and CFO. The limitation also applies to individuals who were covered employees in any year after 2016.

Compensation Tables
(4) These amounts relate solely to the increased present value of the NEO’s pension plan benefits using mandatory SEC assumptions (see the descriptions of these plans under the Pension Benefits Table on page 75 ). The amount accrued in each year differs from the amount accrued in prior years due to an increase in age, service and pay (salary and bonus). The change in pension value is also highly sensitive to changes in the interest rate used to determine the present value of the payments to be made over the life of the executive.
In 2024, the aggregate change in actuarial present value of pension benefits is a negative amount for Mr. Crews (-$3,821), due primarily to increased interest rates. In accordance with SEC rules, the negative amount is reported as $0 in the above table.
Mr. Jones and Mr. Keffer were hired after the Company’s defined benefit pension plans were closed to new entrants, and as a result, they do not participate in any defined benefit pension plans.
There were no above-market earnings in the nonqualified deferred compensation plans (see the descriptions of these plans under the Nonqualified Deferred Compensation Table on page 78 ).
(5)    Amounts include, as applicable, (a) the value of perquisites and personal benefits, (b) basic life insurance premiums, (c) matching contributions through the Northrop Grumman Foundation made to eligible educational institutions and to non-profit organizations under a Company program, (d) Company contributions to defined contribution and deferred compensation plans, and (e) with respect to Dr. Fleming, a one-time tax gross-up of $71,889 to cover costs incurred in connection with a Company-required relocation in accordance with our relocation policy. Where the value of the items reported in a particular category for an NEO exceeded $10,000 in 2024 (other than perquisites and personal benefits, which are subject to different thresholds as described below), those items are identified and quantified below.
Perquisites and Personal Benefits – Perquisites and other personal benefits provided to certain NEOs are as follows: security, travel-related perquisites (including use of Company aircraft and ground transportation services for personal travel and incidental expenses for family members if accompanying the NEO while on business travel), financial planning/income tax preparation services, insurance premiums paid by the Company on the NEO’s behalf, executive physicals and other nominal perquisites or personal benefits. We determine the incremental cost for perquisites and personal benefits based on costs or charges incurred by the Company for the benefits.
As discussed in “Key Components of Our Executive Compensation Programs - Security Arrangements,” the Company provides NEOs with certain residential and travel security protection due to the nature of our business and security threat information. The amounts reflected in the “All Other Compensation” column include expenses for certain residential and travel security that we treat as perquisites under relevant SEC guidance, even though the need for such expenses arises from the risks associated with their positions with the Company. The Company calculates the cost of travel security coverage based on the hourly rates and overhead fees charged directly to the Company by the firms providing security personnel. If Company security personnel are used, their hourly rates are used to calculate the cost of coverage. The Company calculates the value of personal use of Company aircraft based on the incremental cost of each element. Fixed costs that would be incurred in any event to operate Company aircraft (e.g., aircraft purchase costs, maintenance not related to personal trips and flight crew salaries) are not included.
The cost of any category of the listed perquisites and personal benefits did not exceed the greater of $25,000 or 10% of total perquisites and personal benefits for any NEO in 2024, except for the following:
i. Ms. Warden: costs attributable to security protection ($415,952), which includes personal travel on Company aircraft consistent with the Company’s security program ($252,182); and
ii. Dr. Fleming: costs attributable to relocation ($115,541).
Contributions to Plans – In 2024, we made the following Company contributions to the defined contribution and deferred compensation plans:

(1) Mr. Jones and Mr. Keffer were hired after the Company’s defined benefit pension plans were closed to new entrants and as a result, they do not participate in any defined benefit pension plans.
(2) Each NEO’s actual service is as follows: Ms. Warden: 16.3 years, Mr. Crews: 20.3 years, Dr. Fleming: 19.1 years and Ms. Roeder: 22.8 years.
(3) Amounts are calculated using the following assumptions:
the NEO retires on the earliest date he/she could receive an unreduced benefit under each plan;
the form of payment is a single life annuity; and
the discount rate is 5.72% for the Pension Plan, 5.75% for Retirement Plan B and 5.73% for all other plans. The mortality table is the Pri-2012 White Collar mortality table projected generationally with an adjusted version of Scale MP-2021 for all plans.
Pension Plans and Descriptions
Most of the pension plans were closed to new hires in 2008. Prior to that time, the Company consolidated the pension plan provisions from diverse Heritage Formulas to a Cash Balance Formula. Over time, the Company also transitioned officers, including NEOs, from supplemental executive retirement plans to a deferred compensation plan, called the Officers Retirement Account Contribution Plan (ORAC). In addition, all final average pay formulas were frozen as of December 31, 2014.
The pension plans in which NEOs participate are listed below.
ERISA 2 is the ERISA Supplemental Program 2. This plan makes participants whole for benefits they lose under the Pension Plan due to certain Internal Revenue Code limits.
Litton Restoration Plan is the Litton Industries, Inc. Restoration Plan 2. This plan makes participants whole for benefits they lose under the Retirement Plan B due to certain Internal Revenue Code limits.
OSERP II is the Officers Supplemental Executive Retirement Program II. This plan provides a pension benefit for certain Company officers.
Pension Plan is the Northrop Grumman Pension Plan. This is a tax qualified pension plan covering a broad base of Company employees.
Retirement Plan B is the Northrop Grumman Retirement Plan “B”. This is a tax qualified pension plan covering a broad base of Company employees.

Compensation Tables
Pension Plan and Retirement Plan B (Tax Qualified Plans)
The Pension Plan has a heritage (non-cash balance) pension formula that applies to Ms. Roeder (Heritage Formula). This is described in detail in the Heritage Formula table that follows. Prior to 2004, the Company transitioned all the heritage formulas in this plan to a Cash Balance Formula. The Cash Balance Formula is a percentage of pay credited to a hypothetical account, which grows with interest. At retirement, the Cash Balance Account is converted to a monthly pension benefit (further information is included in the Cash Balance Formulas section below). The final benefit from this plan is the sum of the two formulas: the Heritage Formula benefit plus the Cash Balance Formula benefit.
Mr. Crews and Dr. Fleming have pension benefits under a Cash Balance Formula in the Pension Plan and Retirement Plan B, respectively.
Ms. Roeder has pension benefits under two subplans of the Pension Plan due to her transfer between business units. She receives a benefit under the Heritage Formula and a Cash Balance Formula in the Northrop Grumman Electronic Systems Pension Plan, a subplan of the Pension Plan (ES Subplan) based on her employment in this subplan. She also receives a benefit under the Northrop Grumman Retirement Value Plan (RVP Subplan) Cash Balance Formula.
Heritage Formula
The following table summarizes the key features of the Heritage Formula applicable to the eligible NEO.
Feature
ES Subplan
Benefit Formula Eligible Pay x 2%
Eligible Pay (limited by Internal Revenue Code section 401(a)(17)) Salary plus bonus paid while participating in this subplan
Normal Retirement Age 65
Early Retirement Age 58 with 30 years of service or age 60 with 10 years of service
Early Retirement Reduction (for retirements occurring between Early Retirement and Normal Retirement) Benefits are reduced for commencement prior to age 65
Cash Balance Formulas
The RVP Subplan Cash Balance Formula in the Pension Plan is a hypothetical account balance consisting of pay credits plus interest. It has the following features:
pay credits are a percentage of pay that vary based on an employee’s points (age plus service) and are credited monthly. The percentage applicable to Ms. Roeder as of her transfer from the RVP Subplan was 4.5%.
interest is credited at the 30-year U.S. Treasury bond rate. The December 31, 2024 interest credit rate was 4.15%.
eligible pay is salary plus bonus, as limited by Internal Revenue Code section 401(a)(17).
after termination of employment, a participant's vested RVP Subplan Cash Balance benefit may be distributed immediately, regardless of age, in a variety of actuarially equivalent monthly annuities or as a lump sum.

The Cash Balance formula in the Pension Plan and the Retirement Plan B is a hypothetical account balance consisting of pay credits plus interest. It has the following features:
pay credits are a percentage of pay that vary based on an employee’s points (age plus service) and are credited monthly. The range of percentages applicable to the NEOs on December 31, 2024 was 5.5% - 6.5%.
interest is credited at the 30-year U.S. Treasury bond rate subject to a minimum annual interest rate of 2.25%. The December 31, 2024 interest credit rate was 4.15%.
eligible pay is salary plus bonus, as limited by Internal Revenue Code section 401(a)(17).
eligibility for early retirement occurs at age 55 with 10 years of service. Benefits may be reduced if commenced prior to Normal Retirement Age (65).

Compensation Tables
The Potential Termination Payments Table provides estimated payments and benefits that the Company would have provided to each NEO if his or her employment had terminated on December 31, 2024 for the reasons set forth in the table below. The Company stock price is assumed to be $469.29, the closing market price on December 31, 2024, the last trading day of the year. These payments and benefits are payable based on:
the Severance Plan; and
the 2011 Plan and the 2024 Plan and the terms and conditions of equity awards made pursuant to the plan.
Due to the many factors that affect the nature and amount of any benefits provided upon termination events, actual amounts paid or distributed to NEOs may be different from the values shown in the table. Factors that may affect these amounts include timing during the year of the occurrence of the event, our stock price, the NEO’s age and the terms and circumstances of the event. The amounts described below are in addition to an NEO’s benefits described in the Pension Benefits and Nonqualified Deferred Compensation Tables on pages 75 and 78 , respectively, as well as benefits generally available to our employees such as distributions under our savings plan, disability or life insurance benefits and accrued vacation.

Compensation Tables
(1) Mr. Keffer is not included because his last day of employment was February 21, 2025. All of Mr. Keffer's outstanding RSRs and RPSRs were forfeited upon his voluntary termination.
(2) Similar treatment provided for certain “good reason” terminations, as described in “Key Components of Our Executive Compensation Programs - Severance Benefits” found on page 65 ; however, there would be no termination payment in the event of an involuntary termination for cause.
(3) The amounts assume full acceleration, which, as discussed above, may not occur to the extent that it would result in an excise tax that decreases the after-tax value of the awards to an NEO.
(4) Long-term incentive awards result in a benefit under Voluntary Termination and Involuntary Termination Not for Cause only if eligible for retirement treatment under the terms and conditions of the grants.
(5) Represents the following benefits under the Severance Plan, assuming a termination date of December 31, 2024: (i) cash severance equivalent to 1.5x the sum of the annual base salary and target annual bonus, (ii) continued medical/dental coverage for the severance period, (iii) financial planning/income tax preparation fees for the year following termination and (iv) outplacement services up to 15% of salary.

2024 CEO Pay Ratio
We are providing the following information about the relationship of the annual total compensation of our median employee and the annual total compensation of our CEO, Ms. Warden, as of our fiscal year ended December 31, 2024. The pay ratio included in this information is a reasonable estimate calculated in a manner consistent with Item 402(u) of Regulation S-K under the Securities Exchange Act of 1934, as amended (the "Exchange Act").
In accordance with SEC rules, we used the same median employee in 2024 who we identified in the prior year's proxy statement. There were no changes to our global employee population or our compensation plans that would result in a significant change to our pay ratio.
We calculated the median employee’s annual total compensation in the same manner as the CEO’s annual total compensation as calculated in the Summary Compensation Table on page 70 . The median employee’s annual total compensation was $109,782, which includes other forms of compensation such as financial and wellness benefits. The CEO’s annual total compensation was $24,359,199. Based on this information, for 2024 the ratio of the annual total compensation of the CEO to the annual total compensation of the median employee was 222:1.

The following table provides five years of the Company’s compensation and performance history prepared in accordance the Exchange Act and does not necessarily reflect value actually realized by the executives or how our Compensation and Human Capital Committee evaluates compensation decisions in light of Company or individual performance. For information on how our Compensation and Human Capital Committee aligns pay with performance when making compensation decisions, please review the CD&A beginning on page 48 .
Based on the data shown in the table there is general alignment between the ”compensation actually paid” (CAP), as defined by the SEC, and the included metrics. While the CAP calculation includes important compensation elements, it does not reflect the executives ”earned” compensation.

(3) Key components that factor into the amount reported as CAP (in accordance with the SEC definition) are the Company’s year-end stock value and equity awards. Executives receive the value of their equity grants only upon vesting. The value reflected for unvested grants, as calculated in CAP, does not reflect value actually received or realized by the executives during the covered year. The equity component of CAP for fiscal years 2024, 2023, 2022, 2021 and 2020 are further detailed in the table below. The equity values were calculated in accordance with the SEC methodology for determining CAP for each year shown.
The amounts deducted or added in calculating the equity award adjustments are as follows:

The fair value of the grants awarded in the respective years generally correlates with the movement in the Company’s stock price, which is a key driver in the amount of, and change in, CAP. As of the December 31, 2024 measurement date, the fair value of the grants of unvested awards remained relatively consistent compared to the prior year.
T he Company’s relative TSR and operational metrics score determine the number of performance shares that vest for each three-year cycle, ranging from 0 % to 200 % for the 2024, 2023, 2022 and 2021 RPSR grants, and 0 % to 150 % for the RPSR grants awarded in 2020, 2019 and 2018. The executive RPSR performance scores were 107 %, 141 %, 135 %, 122 % and 105 %, in 2024 , 2023, 2022, 2021, and 2020, respectively, which contributed to the incremental change in CAP year-over-year, along with the change in stock price.
Mr. Bedingfield terminated his employment in 2020 and was not retirement eligible. He forfeited nearly $8 million in equity value. The average non-PEO NEO CAP in 2020 was greatly impacted by the forfeited awards. Additional details included in footnote seven.

Pay Versus Performance
(6) Adjusted Cash Flow from Operations*, as defined on page 104 , is the Company Selected Measure (CSM), linking performance for the most recently completed fiscal year to CAP for the PEO and non-PEO NEOs. The selected measure focuses on cash generation for strategy execution and enables management to make capital investment decisions that support long-term profitable growth. For more information, including how the measure is calculated, see “Appendix A - Use of Non-GAAP Financial Measures” on page 104 .
(7) Mr. Bedingfield was the Corporate Vice President and Chief Financial Officer in 2019. He stepped down from his position effective February 17, 2020 and left the Company February 21, 2020. On February 6, 2020 the Company filed a Form 8-K which included, as an exhibit, the Separation Agreement with Mr. Bedingfield. A significant portion of Mr. Bedingfield's LTI awards were forfeited upon termination, amounting in a loss of about $8 million. With Mr. Bedingfield excluded, the average CAP for non-PEO NEOs is $4.5 million.
Tabular List of Performance Measures
In 2024, the greatest impact on the compensation of our PEO and non-PEO NEOs was from the Company’s LTI plan, particularly our performance against the metrics for our RPSRs, which comprise 70% of the LTI award and approximately half of the total direct compensation for our PEO and non-PEO NEOs. The RPSR metrics reflect the Company’s continued emphasis on operational performance directly impacted by management decisions and behaviors, and are set to motivate and reward the PEO and non-PEO NEOs to achieve our long-term objectives. The metrics reinforce the link between the Company’s interests and the interests of our shareholders. For more detail, see the “Key Components of Our Executive Compensation Programs” section. These performance measures align to the Company’s “Compensation Philosophy and Objectives” as described in the CD&A, on page 49 .
In addition, absolute TSR, which reflects our Company's stock value, is another important measure because it has a significant impact on our executives’ required CAP calculation. It is important to note, if absolute TSR is negative, the relative TSR (rTSR) RPSR metric is capped at 100%. Lastly, Adjusted Cash Flow from Operations*, the CSM, focuses on generating cash for strategy execution and enables leaders to make capital investment decisions that support long-term growth. The metric is an important driver for assessing the Company's AIP performance.
These key financial performance measures are as follows:
Performance Measures Type
Adjusted Cumulative FCF* RPSR Metric
Relative TSR RPSR Metric
Return on Invested Capital* (ROIC) RPSR Metric
Absolute TSR Value of LTI
Adjusted Cash Flow from Operations* CSM/AIP Metric
* This metric is a non-GAAP financial measure. For more information, see “Appendix A - Use of Non-GAAP Financial Measures.”

Pay Versus Performance
Relationship Between CAP and Financial Performance Measures
As shown in the chart below, the Company’s three-year cumulative TSR outperformed the companies included in the S&P A&D Index. The PEO and other non-PEO NEOs’ CAP amounts are aligned with the Company’s TSR. This is due primarily to the Company’s use of equity incentives, which are tied directly to stock price in addition to the Company’s financial performance.
1649267454347
Adjusted Cash Flow from Operations * was selected as the CSM to focus on an annual metric, per SEC guidance. This metric emphasizes the importance of generating cash for strategy execution and enables management to make capital investment decisions, which were impacted by lower net tax payments in 2024 as compared to 2023. Since it has a stronger focus on our annual performance rather than long-term performance, the impact of Adjusted Cash Flow from Operations* on CAP is moderate compared to the LTI plan metrics.
While the Company is required to include net income as a metric in the Pay Versus Performance table, we do not believe the metric is an appropriate selection for analyzing CAP, as defined by the SEC. Net income is not used to measure compensation due to the non-operational impacts of the annual mark-to-market pension and other postretirement benefits “OPB“ adjustments, which include actuarial gains and losses that can vary significantly from year to year.

Proposal 3: Ratification of Appointment of Independent Auditor
The Audit and Risk Committee believes that the appointment of Deloitte & Touche LLP (Deloitte) is in the best interests of the Company and its shareholders, and proposes and recommends that the shareholders ratify the Audit and Risk Committee’s appointment of Deloitte as our independent auditor for 2025.
Deloitte served as our independent auditor for 2024, and Deloitte or its predecessors have served as the independent auditor for the Company (including certain of its predecessor companies) since 1975. The Audit and Risk Committee is responsible for the appointment, compensation, retention, oversight, evaluation and termination, if necessary, of our independent auditor. In determining whether to retain Deloitte or engage another independent registered public accounting firm as the Company’s independent auditor, at least annually the Audit and Risk Committee, with management and our internal auditors, reviews and evaluates Deloitte’s performance and independence. As part of its review, the Audit and Risk Committee may consider, among other things, the following:
the quality and efficiency of Deloitte’s current and historical services provided to the Company;
Deloitte’s capability, expertise and efficiency in handling the breadth and complexity of the Company’s global businesses and operations;
the quality and candor of Deloitte’s communications with the Audit and Risk Committee;
Deloitte’s independence from the Company;
the appropriateness of Deloitte’s fees; and
Deloitte’s tenure as our independent auditor (including its knowledge of the Company and its operations, accounting policies and practices and internal controls).
Based on its evaluation, the Audit and Risk Committee believes that Deloitte is independent and well-qualified to serve as the Company’s independent auditor in 2025.
The Audit and Risk Committee also reviews the performance of Deloitte’s lead audit partner, and the Audit and Risk Committee and its Chair oversee the rotation of Deloitte’s lead audit partner and are involved in the selection and approval of the lead audit partner. The lead audit partner rotates every five years in accordance with regulatory requirements. In addition, the Audit and Risk Committee is responsible for reviewing and pre-approving audit and non-audit services and related fees for the independent auditor.
Although ratification is not required by our Bylaws or otherwise, the Audit and Risk Committee is submitting the selection of Deloitte to shareholders as a matter of good corporate governance. If the shareholders fail to ratify the appointment of Deloitte, the Audit and Risk Committee will consider this in its selection of auditor for the following year. A representative from Deloitte will attend the Annual Meeting and will have the opportunity to make a statement and respond to appropriate questions.

Audit fees for 2024 and 2023 also include $1,850,000 and $1,925,000, respectively, for foreign statutory audits. Fees for foreign statutory audits are reported in the year in which the audits are performed. For example, foreign statutory audit fees reported in 2024 relate to audits of the Company’s foreign entities for the fiscal year ended 2023. The remaining 2024 audit fees primarily relate to audit services associated with the Company’s Form 8-K filing in connection with its debt offering in January 2024, the Company’s Form S-8 filing in July 2024 and testing procedures associated with the Company's implementation of the S/4HANA enterprise resource planning system and international general IT controls.

(2) Audit-related fees reflect fees for services that are reasonably related to the performance of the audit or review of the Company’s financial statements. There were no additional audit-related fees in 2024 or 2023. Audit-related fees exclude fees related to benefit plan audits, which are paid for by the plans, that totaled $1,538,000 for 2024 and $1,496,000 for 2023.
(3) Tax-related fees during 2024 and 2023 reflect fees of $418,000 and $363,000, respectively, for services concerning foreign income tax compliance, foreign Value Added Tax compliance and other tax matters.
(4) All other fees during 2024 reflect fees of $25,000 for services concerning the Company's allocation of hydrofluorocarbon allowances.
Policy on Audit and Risk Committee Pre-Approval of Audit and Permissible Non-Audit Services
It is the Audit and Risk Committee’s policy to pre-approve all audit and permitted non-audit services provided by our independent auditor in order to provide reasonable assurance that the provision of these services does not impair the auditor’s independence. Pre-approval may be given at any time. The Audit and Risk Committee has delegated pre-approval authority for any individual project up to $1 million to the Chair of the Audit and Risk Committee.
The decisions of the Chair to pre-approve a permitted service are reported to the Audit and Risk Committee at its next meeting. The independent auditor is required to periodically report to the full Audit and Risk Committee regarding the extent of services provided by the independent auditor in accordance with this pre-approval policy, as well as the fees for the services performed to date.
The Audit and Risk Committee approved all audit and non-audit services provided by Deloitte, the member firms of Deloitte Touche Tohmatsu Limited and their respective affiliates during 2024 and 2023, in each case before being engaged to provide those services.
Audit and Risk Committee Report
The Audit and Risk Committee of the Board of Directors is responsible for assisting the Board of Directors in fulfilling its oversight responsibilities over the Company’s accounting, auditing and financial reporting processes and financial risk assessment and management process, and for monitoring compliance with certain regulatory and compliance matters. The Audit and Risk Committee’s written charter describes the Audit and Risk Committee’s responsibilities and has been approved by the Board of Directors.

Proposal 3: Ratification of Appointment of Independent Auditor
Deloitte & Touche LLP (Deloitte), the Company’s independent auditor, is responsible for performing an independent audit of the Company’s consolidated financial statements and expressing an opinion on the conformity of the financial statements with accounting principles generally accepted in the United States of America, and on the effectiveness of the Company’s internal control over financial reporting.
In connection with the preparation of the Company’s financial statements as of and for the year ended December 31, 2024, the Audit and Risk Committee reviewed and discussed the audited financial statements with the Company’s Chief Executive Officer, Chief Financial Officer, Chief Accounting Officer and Deloitte. The Audit and Risk Committee also discussed with Deloitte the communications required under applicable requirements of the Public Company Accounting Oversight Board (PCAOB) and the SEC, including the matters required to be discussed by Auditing Standard No. 1301, Communications with Audit Committees, as adopted by the PCAOB, and, with and without management present, discussed and reviewed the results of Deloitte’s examination of the financial statements. Additionally, the Audit and Risk Committee discussed with the Company’s internal auditors the results of their audits completed during 2024.
The Audit and Risk Committee received the written disclosures and the letter from Deloitte required by the applicable requirements of the PCAOB regarding the independent auditor’s communications with the Audit and Risk Committee concerning independence. In addition, the Audit and Risk Committee discussed with Deloitte that firm’s independence from the Company.
Based on the Audit and Risk Committee’s review and discussions described in this report, the Audit and Risk Committee recommended to the Board of Directors and the Board of Directors approved that the audited financial statements for the year ended December 31, 2024 be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 for filing with the SEC.

Proposal 4: Shareholder Proposal
Mr. John Chevedden, 2215 Nelson Avenue, No. 205, Redondo Beach, California 90278, a beneficial owner of 20 shares of common stock of the Company, has stated that he intends to present the following proposal at the Annual Meeting. The proposal and supporting statement, for which the Board accepts no responsibility, has been reproduced below without modification. The Board opposes the shareholder proposal for the reasons stated below.

Proposal 4 - Support Improved Clawback Policy regarding Unearned Executive Pay
Chevedden Image.jpg

Shareholders ask the Board of Directors to amend the Company Policy on recoupment of incentive pay to apply to the each Named Executive Officer and to state that conduct or negligence - not merely misconduct - shall trigger mandatory application of that policy. Also the Board shall report to shareholders in each annual meeting proxy the results of any deliberations regarding the policy, including the Board's reasons for not applying the policy after specific deliberations conclude, about whether or not to cancel or seek recoupment of unearned compensation paid, granted or awarded to NEOs under this policy.

This improved clawback policy shall at least be included in the Governess Guidelines of the Company or similar document and be easily accessible on the Company website.

The current Clawback Policy is incomplete and can be difficult for shareholders to access.

Wells Fargo offers a prime example of why Northrop Grumman (NOC) needs a stronger policy. After 2016 Congressional hearings, Wells Fargo agreed to pay $185 million to resolve claims of fraudulent sales practices. The Wells Fargo Board then moved to claw back $136 million from 2 top executives. Wells Fargo unfortunately concluded that the CEO had only turned a blind eye to the practice of opening fraudulent accounts and thus failed to attempt any clawback and left $136 million on the table.

At minimum this proposal alerts NOC shareholders that NOC executives can now be richly rewarded even when they are negligent. This is the wrong incentive for NOC executives at a time when the best incentives for NOC executives should be adopted.

Please vote yes:
Support Improved Clawback Policy regarding Unearned Executive Pay -

Proposal 4: Shareholder Proposal
Board of Directors’ Statement in Opposition to Proposal 4
The Board of Directors recommends that shareholders vote against Proposal 4. We believe that implementation of this proposal is unnecessary given the Company’s comprehensive recoupment policy which promotes executive accountability and protects shareholder interests and is fully compliant with the required recoupment provisions under NYSE and SEC rules.
Our current recoupment policy is comprehensive and effectively protects the interests of our shareholders.
Northrop Grumman has a comprehensive Policy Regarding the Recoupment of Certain Incentive Compensation Payments (Company Recoupment Policy) 1 . The Company Recoupment Policy requires the Company to attempt to recover certain incentive compensation from executive officers, regardless of the executive officer’s personal culpability, in the event the Company is required to prepare an accounting restatement due to, among other things, the material noncompliance of the Company with any financial reporting requirement under U.S. federal securities laws . This ensures that all executive officers, including the named executive officers, are held accountable for material inaccuracies in previously issued financial statements without the burden of proving fault – a lower threshold than the “conduct or negligence” threshold requested by the proposal. As mentioned above, these provisions meet the required recoupment provisions under NYSE and SEC rules.
The Company Recoupment Policy goes beyond the required recoupment provisions by also permitting the Board to seek recovery of incentive payments from all elected officers, not just NEOs, due to certain conduct, including fraud, bribery or illegal acts that caused significant financial or reputational harm to the Company. In addition, the Company Recoupment Policy further provides for the right to recover incentive payments from elected officers for certain instances of gross negligence in failing to supervise other employees and failure to report certain misconduct of others. Finally, the Company Recoupment Policy permits the CEO to require reimbursement of incentive payments made to non-executive employees in certain circumstances. These provisions, along with the no-fault provision described above, provide a comprehensive system of accountability that addresses a broad range of actions by executive officers and other employees and provide a framework that we believe is better for our Company and shareholders than the provisions proposed in Proposal 4.
Implementation of Proposal 4 could also result in actions that would not be in the best interests of shareholders. Proposal 4 seeks to amend the Company Recoupment Policy to trigger recoupment of incentive pay whenever an NEO has engaged in “conduct or negligence” – terms that are incredibly broad and subject to any number of interpretations with no guidance from the proposal as to how this should be implemented. By mandating recoupment for almost any conduct by an NEO, even neutral conduct or conduct beneficial to the Company and its shareholders, Proposal 4 could discourage executive officers from exercising the business judgment necessary to evaluate complex business decisions and deliver shareholder value, causing a chilling effect on the executive decision-making necessary to deliver the best results for our shareholders. In addition, given the overly broad and uncertain terms used in the proposal, such as “conduct” and “negligence”, confusion in the application of the resulting recoupment policy could also harm the Company’s ability to attract and retain qualified executives.
The Company Recoupment Policy is carefully designed to promote clarity around the circumstances under which the recoupment of incentive compensation may be warranted, while providing the Board with the necessary authority and discretion to act in the best interests of the Company and its shareholders by taking into account particular facts and circumstances. Mandating prescriptive measures, as suggested in the proposal, would inhibit the Board’s ability to exercise sound judgment in the complex situations surrounding recovery of incentive compensation. Proposal 4 risks creating a one-size-fits-all approach to executive accountability, which creates risk that recoupment would be triggered when such action is not warranted.
We are dedicated to maintaining a reputation for the highest levels of ethics, integrity and transparency.
We are dedicated to maintaining high standards of corporate governance and strive to maintain a culture of accountability in which ethical conduct is encouraged and rewarded and improper conduct is appropriately addressed. In addition to the Company Recoupment Policy, we also maintain Standards of Business Conduct, which define our expectations for ethical decision-making, responsibility and accountability and apply to all employees, including our executive officers.
With respect to transparency surrounding recoupment efforts, the Company is committed to disclosing the aggregate amount recovered if the underlying event has previously been disclosed by the Company in its filings with the SEC or otherwise, and disclosure is permitted. Therefore, the proposal’s request that the Board “report to shareholders in each annual meeting proxy the results of any deliberations regarding the policy…about whether or not to cancel or seek recoupment…” is unnecessary. The Company’s commitment to ethical conduct, accountability and transparency is rooted in our culture. Our executives seek to embody our values and act with integrity in all that they do. Together with our Company Recoupment

Proposal 4: Shareholder Proposal
Policy, we believe our policies and practices address the issues of proper business conduct and appropriate accountability for our executives in a way that protects shareholder interests.
In summary, the Board of Directors recommends that shareholders vote against Proposal 4. Our Company Recoupment Policy already provides a comprehensive mechanism for accountability and implementing the proposal would therefore be unnecessary and would also create confusion and complexity which would result in outcomes that may not be in the best interests of shareholders.
Vote Required
Approval of this proposal requires that the votes cast “for” the proposal exceed the votes cast “against” the proposal. Abstentions and broker non-votes will have no effect on this proposal.

Transactions with Related Persons and Control Persons
Related Person Transactions
The Company has a written policy approved by the Board, for the review, approval and ratification of transactions between our Company and our directors, executive officers and other related persons. A copy of the policy is available on the Investor Relations section of our website ( www.northropgrumman.com ). The policy provides for related person transactions to be reviewed in advance and approved or ratified, as applicable, by the Board of Directors, the Nominating and Corporate Governance Committee or the Chair of the Nominating and Corporate Governance Committee. A related person transaction may be approved if, after reviewing the relevant facts and circumstances, the reviewing party concludes that approving the related person transaction is in the best interests of the Company and its shareholders.
The policy defines a related person transaction as any transaction in which the Company was, is or will be a participant, where the amount involved exceeds $120,000, and in which a related person had, has or is expected to have a direct or indirect material interest. A “related person” includes:
any of our directors, nominees for director or executive officers;
any person who is known to be the beneficial owner of more than 5% of our common stock; or
an immediate family member of any such persons.
Under exceptional circumstances, if a related person transaction has not been approved in advance, the Nominating and Corporate Governance Committee will recommend to the Board of Directors such action as the Nominating and Corporate Governance Committee deems appropriate, including ratification, amendment or termination of the transaction.
The policy requires each director and executive officer to complete an annual questionnaire to identify his or her related interests and to notify the Corporate Secretary of any changes in their information.
During 2024, the Company employed one family member of an executive officer who received compensation in excess of the reporting threshold. The spouse of our Corporate Vice President and President, Defense Systems, Ben Davies, was employed by the Company as a Senior Manager, Electronics Engineering, in our Mission Systems sector. She received cash compensation of approximately $182,400 and participated in the Company’s benefit plans, commensurate with her position at the Company.
State Street Corporation (State Street), acting in various fiduciary capacities, filed a Schedule 13G/A with the SEC reporting that as of December 31, 2023, State Street and certain of its subsidiaries collectively were the beneficial owners of more than 5% of our outstanding common stock. A subsidiary of State Street is the trustee for various Northrop Grumman defined benefit and defined contribution plan trusts. Two other State Street subsidiaries provide investment management services. During 2024, those State Street subsidiaries received approximately $5.6 million for such services, all of which was paid by the plan trusts.
BlackRock, Inc. (BlackRock) filed a Schedule 13G/A with the SEC reporting that as of September 30, 2024, BlackRock and certain of its subsidiaries collectively were the beneficial owners of more than 5% of our outstanding common stock. A subsidiary of BlackRock provides investment management services for certain assets within various Northrop Grumman defined benefit plan trusts. During 2024, the trusts paid that BlackRock subsidiary approximately $230,000 for such services.
Indemnification Agreements
Our Bylaws require us generally to indemnify our directors and executive officers to the fullest extent permitted by Delaware law. Additionally, as permitted by Delaware law, we have entered into indemnification agreements with each of our directors and elected officers. Under the indemnification agreements, we have agreed to hold harmless and indemnify each indemnitee, generally to the fullest extent permitted by Delaware law, against expenses, liabilities and loss incurred in connection with threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative to which the indemnitee is made a party by reason of the fact that the indemnitee is or was a director or officer of the Company or any other entity at our request, provided however, that the indemnitee acted in good faith and in a manner reasonably believed to be in the best interests of our Company.

Questions and Answers About
the Annual Meeting
How do I attend the Annual Meeting?
The Annual Meeting will be held exclusively online via live webcast at www.virtualshareholdermeeting.com/NOC2025 on May 21, 2025. To be admitted to the Annual Meeting via the website, shareholders must enter the 16-digit voting control number found on their proxy card, voting instruction form, notice of internet availability of proxy materials, or email notification. You may begin to log into the website beginning at 7:45 AM Eastern Daylight Time. The meeting will begin promptly at 8:00 AM Eastern Daylight Time. If you encounter any technical difficulties, please call the number posted to the online webcast (it will be available starting at 7:45 AM Eastern Daylight Time and remain available for the duration of the meeting). We will disclose additional details about the Annual Meeting or changes to the process on the Investor Relations section of our website (w ww.northropgrumman.com ) and/or in a public filing with the SEC, as appropriate.
Why did I receive a “Notice of Internet Availability of Proxy Materials” but not a full set of proxy materials?
We distribute our proxy materials to shareholders via the internet under the “Notice and Access” approach permitted by the rules of the SEC. This approach reduces the environmental impact of the Annual Meeting and our distribution costs, while providing a timely and convenient method of accessing the proxy materials and voting. On April 4, 2025, we mailed a “Notice of Internet Availability of Proxy Materials” to participating shareholders, containing instructions on how to access the proxy materials.
Who is entitled to vote at the Annual Meeting?
You may vote your shares of our common stock if you owned your shares as of the close of business on March 25, 2025 (Record Date). As of the Record Date, there were 144,138,702 shares of our common stock outstanding. You may cast one vote for each share of common stock you hold as of the Record Date on all matters presented.
How many votes must be present to hold the Annual Meeting?
The presence virtually or by proxy of the holders of a majority of the shares entitled to vote at the Annual Meeting will constitute a quorum at the Annual Meeting. Persons returning executed proxy cards will be counted as present for purposes of establishing a quorum even if they abstain from voting on any or all proposals. Shares held by brokers who vote such shares on any proposal and broker non-votes will be counted as present for purposes of establishing a quorum.
How can I receive a paper copy of the proxy materials?
Instead of mailing a printed copy of this Proxy Statement and accompanying materials to each shareholder of record, we have elected to provide a Notice of Internet Availability of Proxy Materials (Notice) as permitted by the rules of the SEC. The Notice instructs you as to how you may access and review all of the proxy materials and how you may provide your proxy. If you would like to receive a printed or electronic copy of this Proxy Statement and accompanying materials, you must follow the instructions for requesting such materials included in the Notice.
Will I have an opportunity to ask questions before or during the Annual Meeting?
Shareholders entitled to vote will be able to submit questions relevant to the business of the meeting during the meeting via www.virtualshareholdermeeting.com/NOC2025 by typing the question into the "Ask a Question" box and clicking “Submit.” In order to ask a question, shareholders will need to have a valid voting control number. You may also submit a question in advance of the meeting at www.proxyvote.com by logging in with the 16-digit voting control number found on your proxy card, voting instruction form, Notice, or email notification. Once you are past the login screen, click on “Questions for Management,” type in your question and click “Submit.” All questions should relate to the official business of the meeting, and management and shareholder proposals in particular. Management will seek to answer questions at the relevant time, when the proposal or matter is up for consideration.

Questions and Answers About the Annual Meeting

Abstentions

Shareholder Proposal to Support Improved Clawback Policy regarding Unearned Executive Pay
(Proposal 4)
AGAINST Majority of votes cast No effect No effect Voted “AGAINST“
What is a broker non-vote?
Brokers who hold shares of common stock for the accounts of their clients may vote these shares either as directed by their clients or in their own discretion if permitted by the stock exchanges or other organizations of which they are members. Members of the New York Stock Exchange (NYSE) are permitted to vote their clients’ proxies in their own discretion on certain matters if the clients have not furnished voting instructions within ten days of the meeting. However, NYSE Rule 452 defines various matters as “non-routine,” and brokers who have not received instructions from their clients do not have discretion to vote their client’s shares on such “non-routine” matters, resulting in a “broker non-vote.”
If you are a beneficial owner whose shares are held of record by a broker, your broker has discretionary voting authority under NYSE rules to vote your shares, without instructions from you, on the ratification of the appointment of Deloitte & Touche LLP as independent auditor. However, your broker does not have discretionary authority to vote your shares, without instructions from you, on the election of directors, the advisory vote to approve the compensation of our NEOs, or the shareholder proposal , in which case a broker non-vote will occur and your shares will not be voted on these matters.
How do I vote my shares if they are registered directly in my name?
If your shares are registered directly in your name with our transfer agent, Computershare Trust Company, N.A., you are considered the “registered shareholder” of those shares, and you may vote by proxy prior to the Annual Meeting, as discussed below, or you may vote online during the Annual Meeting. Shares represented by a properly executed proxy will be voted at the Annual Meeting in accordance with the shareholder’s instructions. If no instructions are given, the shares will be voted according to the recommendations of the Board. Registered shareholders may go to www.proxyvote.com to view this Proxy Statement and the Annual Report.

DURING THE ANNUAL MEETING
Registered shareholders may vote during the Annual Meeting online at www.virtualshareholdermeeting.com/NOC2025 . If you have already voted online, by telephone, by QR code or by mail, your vote during the Annual Meeting will supersede your earlier vote.
If any other matters are properly brought before the Annual Meeting, the proxy card gives discretionary authority to the proxyholders named on the card to vote the shares in their best judgment. A shareholder who executes a proxy may revoke it at any time before its exercise by delivering a written notice of revocation to the Corporate Secretary or by delivering a valid, later-dated proxy, or a later-dated vote by telephone or on the internet, in a timely manner. In addition, a shareholder attending the Annual Meeting may revoke the proxy by voting during the meeting.
How do I vote my shares if they are held by a bank, broker or other nominee?
If your shares are held in a stock brokerage account or by a bank or other nominee (that is, in street name), you are considered the “beneficial owner” of the shares that are registered in the street name. You are able to vote those shares, to attend the Annual Meeting as a shareholder, and to ask questions at the meeting. You will need to instruct the bank, broker or other nominee how to vote these shares using the procedure identified by the bank, broker or other nominee. You should receive voting instruction forms from your bank, broker or other nominee. We expect most banks, brokers and other nominees to enable beneficial owners to provide voting instructions by telephone or on the internet. Beneficial owners may view this Proxy Statement and the Annual Report on the internet by logging on to www.proxyvote.com .
Beneficial owners who hold shares in “street name” may revoke a proxy or change a vote by submitting a new, later-dated voting instruction form, contacting the bank, broker or other nominee or by voting during the Annual Meeting. If the Notice or voting instruction form that you received does not indicate that you may vote your shares through the www.proxyvote.com website, you should contact your bank, broker, or other nominee (preferably at least five days before the meeting) and obtain your 16-digit control number that will allow you to attend, participate in, and vote at the meeting.
How do I vote my shares held under a Northrop Grumman savings plan?
If shares are held on an individual’s behalf under any of our savings plans, the proxy will serve to provide confidential instructions to the plan Trustee or Voting Manager who then votes the participant’s shares in accordance with the individual’s instructions. For those participants who do not vote their plan shares, the applicable Trustee or Voting Manager will vote their plan shares in the same proportion as shares held under the plan for which voting directions have been received, unless the Employee Retirement Income Security Act requires a different procedure.
Savings plan participants may submit their voting instructions by the same methods as registered shareholders (see “How do I vote my shares if they are registered directly in my name?” above) but voting instructions from savings plan participants must be received by the applicable plan Trustee or Voting Manager by 11:59 p.m. Eastern Daylight Time on May 18, 2025 in order to be used by the plan Trustee or Voting Manager to determine the votes cast with respect to plan shares.

not earlier than December 5, 2025 and not later than January 4, 2026, if the nomination is submitted pursuant to the Bylaws, but not pursuant to our proxy access provision, in which case we are not required to include the nomination in our proxy materials (except as may be required in our proxy card pursuant to Rule 14a-19). If the 2026 Annual Meeting is convened more than 30 days prior to or delayed by more than 30 days after the one-year anniversary of the Annual Meeting, our Bylaws provide different notice requirements.

Householding Information
Some banks, brokers and other nominee record holders may be participating in the practice of “householding.” This means that only one copy of the Notice of Internet Availability of Proxy Materials may have been sent to multiple shareholders in a household. We will promptly deliver a separate copy to a shareholder upon written or oral request to the Corporate

Cost of Soliciting Proxies
We will pay all costs of soliciting proxies. We have made arrangements with brokerage houses and other custodians, nominees and fiduciaries to make proxy materials available to beneficial owners. We will, upon request, reimburse them for reasonable expenses incurred. We have retained D.F. King & Co., Inc. of New York at an estimated fee of $22,500, plus reasonable disbursements to solicit proxies on our behalf. Our officers, directors and regular employees may solicit proxies personally, by means of materials prepared for shareholders and employee-shareholders or by telephone or other methods to the extent deemed appropriate by the Board.
No additional compensation will be paid to such individuals for this activity. The extent to which this solicitation will be necessary will depend upon how promptly proxies are received. We therefore urge shareholders to give voting instructions without delay.

Appendix A – Use of Non-GAAP Financial Measures
This Proxy Statement contains non-GAAP (accounting principles generally accepted in the United States of America) financial measures, as defined by SEC Regulation G and indicated by an asterisk in this Proxy Statement. While we believe investors and other users of our financial statements may find these non-GAAP financial measures useful in evaluating our financial performance and operational trends, they should be considered as supplemental in nature, and therefore, should not be considered in isolation or as a substitute for financial information prepared in accordance with GAAP. Definitions for the non-GAAP financial measures contained in this Proxy Statement are provided below and the reconciliations of non-GAAP financial measures presented in this Proxy Statement are located on pages 107 to 108 of this Appendix A. Other companies, including companies in our industry, may define these measures differently or may utilize different non-GAAP financial measures, limiting the usefulness of those measures for comparative purposes between companies.
Certain non-GAAP financial measures below are used as internal measures for performance-based compensation decisions, as further discussed in the “Key Components of Our Executive Compensation Programs” section of the Compensation Discussion and Analysis. The Compensation and Human Capital Committee has discretion to make adjustments to these measures in instances where the Company’s performance has been impacted by unforeseen or unusual events. For 2024, 2023 and 2022, the Compensation and Human Capital Committee adjusted the calculation of certain measures in order to exclude the impact of certain events or transactions that were not contemplated when the performance metrics were established.
Cash Flow Metrics : We use cash flow metrics as internal measures of financial performance and for performance based compensation decisions. We also use these measures as a key factor in our planning for, and consideration of, acquisitions, payments of dividends and share repurchases. The following cash flow metrics may be useful to investors and other users of our financial statements as supplemental measures of our cash performance, but should not be considered in isolation, as measures of residual cash flow available for discretionary purposes, or as alternatives to operating results presented in accordance with GAAP. All cash flow metrics are reconciled below.
Free Cash Flow : Net cash provided by operating activities, less capital expenditures. We use free cash flow as a key factor in our planning for, and consideration of, acquisitions, the payment of dividends and stock repurchases.
Adjusted Free Cash Flow (Adjusted FCF) : Net cash provided by operating activities, less capital expenditures, plus proceeds from the sale of equipment to a customer (not otherwise included in net cash provided by or used in operating activities) and the after-tax impact of discretionary pension contributions, if any. Adjusted Free Cash Flow includes proceeds from the sale of equipment to a customer as such proceeds were generated in a customer sales transaction. It also includes the after-tax impact of discretionary pension contributions for consistency and comparability of financial performance.
Adjusted Free Cash Flow Before After-Tax Total Pension Funding : Adjusted Free Cash Flow, as defined above, before the after-tax impact of required pension funding, as approved by the Compensation and Human Capital Committee.
Adjusted Cumulative Free Cash Flow (Adjusted Cumulative FCF) : The aggregate Adjusted Free Cash Flow Before After-Tax Total Pension Funding, as defined above, over a three-year period and after cash flow adjustments, as approved by the Compensation and Human Capital Committee, to adjust for unanticipated impacts to this measure for each three-year period since initial grant setting. As approved by the Compensation and Human Capital Committee, the 2022 grant excludes CAS pension recovery over the three-year period, the impact of unanticipated cash expenditures on a Space Systems program due to international trade restrictions, federal and state tax impacts associated with the sale of a minority investment in an international business, plan-based differences in free cash flow related to unanticipated costs on the B-21 program, and assumptions regarding tax legislation related to research credits at initial grant setting.
Adjusted Cash Flow from Operations : Net cash provided by operating activities, adjusted to include proceeds from sale of equipment to a customer (not otherwise included in net cash provided by operating activities) and to exclude transaction costs as well as federal and state income taxes associated with the IT services divestiture, the after-tax impact of discretionary pension contributions, if any, and other cash flow adjustments as approved by the Compensation and Human Capital Committee. Adjusted Cash Flow from Operations includes proceeds from the sale of equipment to a customer as such proceeds were generated in a customer sales transaction. It excludes the after-tax impact of discretionary pension contributions for consistency and comparability of financial performance. As approved by the Compensation and Human Capital Committee, the 2024 metric has been adjusted to exclude CAS pension recovery. As approved by the Compensation and Human Capital Committee, the 2023 metric has been adjusted to exclude CAS pension recovery, cash received from certain federal and state tax settlements, and the federal and state tax impacts of

the sale of a minority investment in an international business. As approved by the Compensation and Human Capital Committee, the 2022 metric has been adjusted to exclude CAS pension recovery, assumptions regarding tax legislation related to research credits at the time of grant setting, unanticipated costs related to a Space Systems program due to international trade restrictions, and certain delayed costs related to the IT services divestiture.
Pension-Adjusted Metrics : For financial statement purposes, we account for our employee pension plans in accordance with GAAP (FAS). However, the cost of these plans is charged to our contracts in accordance with the Federal Acquisition Regulation (FAR) and the related U.S. Government Cost Accounting Standards (CAS) that govern such plans. We use pension-adjusted metrics as internal measures of financial performance and for performance-based compensation decisions.
The FAS/CAS operating adjustment referred to below reflects the difference between CAS pension expense included as cost in segment operating income and the service cost component of FAS expense included in total operating income. The total net FAS/CAS pension adjustment referred to below reflects the combined FAS/CAS operating adjustment and Non-operating FAS pension benefit. The following pension-adjusted measures may be useful to investors and other users of our financial statements in evaluating our performance based upon the pension costs charged to our contracts. All pension-adjusted metrics are reconciled below.
Pension-Adjusted Operating Income : Operating income before the FAS/CAS operating adjustment as defined above and excluding unallocated state tax impacts reflected within unallocated corporate income (expense). As approved by the Compensation and Human Capital Committee, this metric has been adjusted to exclude Orbital ATK intangible asset amortization and property, plant and equipment (PP&E) step-up depreciation.
Pension-Adjusted Operating Margin (OM) Rate : Pension-Adjusted Operating Income as defined above, divided by sales.
Segment Operating Income and Segment Operating Margin Rate: Segment Operating Income and Segment Operating Margin Rate (Segment Operating Income divided by sales) reflect the combined operating income of our four segments less the operating income associated with intersegment sales. Segment Operating Income includes pension expense allocated to our sectors under FAR and CAS and excludes FAS pension service expense and unallocated corporate items. These measures may be useful to investors and other users of our financial statements as supplemental measures in evaluating the financial performance and operational trends of our sectors. These measures should not be considered in isolation or as alternatives to operating results presented in accordance with GAAP.
MTM-Adjusted Net Earnings : Net earnings excluding MTM expense and related tax impacts. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the Company’s underlying financial performance by presenting the Company’s operating results before the non-operational impact of pension and OPB actuarial gains and losses. This measure is also consistent with how management views the underlying performance of the business as the impact of MTM accounting is not considered in management’s assessment of the Company’s operating performance or in its determination of incentive compensation awards.
MTM-Adjusted EPS : Diluted earnings per share excluding the per share impact of MTM benefit (expense) and related tax impacts. This measure may be useful to investors and other users of our financial statements as a supplemental measure in evaluating the company’s underlying financial performance per share by presenting the company’s diluted earnings per share results before the non-operational impact of pension and OPB actuarial gains and losses.
Pension-Adjusted Net Operating Profit After-Tax (Pension-Adjusted NOPAT) : MTM-Adjusted Net Earnings, as defined above, adjusted to exclude interest expense, Orbital ATK intangible asset amortization and PP&E step-up depreciation and net FAS/CAS pension adjustment, as defined above, after taxes and other earnings adjustments as approved by the Compensation and Human Capital Committee. For the 2022 grant, this metric has been adjusted to exclude unanticipated impacts to this measure for each three-year period since initial grant setting. Approved adjustments include a charge on the low-rate initial production phase of the B-21 program (including the related federal and state tax impacts), the gain on sale of a minority investment in an international business, the loss on divestiture of a small international subsidiary, as well as the federal tax impacts of each sale.
Return on Invested Capital (ROIC ) : The three-year average of Pension-Adjusted NOPAT, as defined above, divided by the three-year average of invested capital, as defined below.
Invested Capital : Shareholder’s equity plus total long-term debt, net of cash and cash equivalents. As approved by the Compensation and Human Capital Committee, Invested Capital excludes the impact on retained earnings related to accumulated other comprehensive income (loss) (AOCI/(AOCL), cumulative MTM benefits (expenses) from 2021 onward after federal and state taxes, and the 2021 IT services divestiture, including the gain on sale of the business, associated federal and state income tax expenses, transaction costs, and the make-whole premium for early debt redemption. Approved adjustments also include impacts resulting from the charge on the low-rate initial production phase of the B-21 program (including the related federal and state tax impacts), plan-based differences in free cash flow related to unanticipated costs on the B-21 program, assumptions regarding tax legislation related to research credits at the time of grant setting, the gain

(1) MTM expense is expected to be deductible on our future state tax returns. The deferred state tax benefit was calculated using the Company’s blended state tax rate of 5.25 percent and included in Unallocated corporate (income) expense within operating income.
(2) The federal tax impact in each period was calculated by subtracting the deferred state tax impact from MTM benefit (expense) and applying the 21 percent federal statutory r ate.
